In order to make the technical means, creative features, goals and functions achieved by the utility model clearer and easier to understand, the utility model is further explained below in conjunction with the drawings and specific implementations:

As shown in Figure 1 and Figure 2, the present invention proposes a mixing device with an automatic weighing device 2, which includes: a mixing box 1 with a cavity for loading materials to be mixed; a weighing device 2. It includes: weighing device 21, support table 22, discharge pipe 23 and funnel 3. A weighing device 21 is installed on the top of the mixing box 1, and a support table 22 is supported on the weighing device 21, and the support table 22 is fixed On the discharge pipe 23, the discharge pipe 23 is connected to the cavity after passing through the weigher 21 and the mixing box 1, the top of the discharge pipe 23 is connected to the small end of the funnel 3; the stirring device 4 is installed in the mixing box 1 and extend into the cavity; and an opening adjustment device 5, which is installed on the discharge pipe 23, and the opening adjustment device 5 is used to adjust the opening of the discharge pipe 23.

In order to design the opening adjustment device 5 with a simple structure, the opening adjustment device 5 includes an opening and closing piece 51 and a limiting component 52. The opening and closing piece 51 extends into the discharge pipe 23, and the opening and closing piece 51 can be opposite to the discharge pipe. 23 moves in the horizontal direction, and a limit component 52 is installed on the opening and closing piece 51. The limit component 52 functions with the discharge pipe 23 or the supporting table 22. The limit component 52 is used to restrict the opening and closing piece 51 relative to the discharge pipe 23. Moving, the opening and closing piece 51 is used to open and close the discharge pipe 23. The position of the opening and closing piece 51 is closely related to the opening of the discharge pipe 23, so that the position of the opening and closing piece 51 can be moved to realize the function of adjusting the opening of the discharge pipe 23. The subsequent design of the limit assembly 52 is to stabilize the opening The adjusted position of the closing piece 51 avoids the need to manually control the position of the opening and closing piece 51, which may cause the phenomenon of manipulation of the energy.

In order to design the limit assembly 52 with a simple structure, the limit assembly 52 includes a first rack 521, a mounting plate 522, a limit pin 523, and a first spring 524. A first rack 521 is installed on the top surface of the support table 22, The first rack 521 and the opening and closing plate 51 are parallel to the moving direction of the discharge pipe 23. The mounting plate 522 is fixed to the opening and closing plate 51. The installation plate 522 exposes the discharge pipe 23. A limit pin 523 is installed on the installation plate 522 to limit the position. The pin 523 is perpendicular to the first rack 521. The limiting pin 523 can move relative to the mounting plate 522. The limiting pin 523 is fixed to one end of the first spring 524, and the other end of the first spring 524 is fixed to the mounting plate 522. The limit pin 523 can be kept engaged with the rack under the elastic force. The mounting plate 522 provides an installation foundation for the installation of the limit pin 523 and the first spring 524. The cooperation of the first rack 521 and the limit pin 523 realizes the limit of the position of the opening and closing plate 51, avoiding the opening and closing plate 51. Move at will, and set the first spring 524 at the same time to realize the state of keeping the limit pin 523 engaged with the first rack 521 under the elastic force of the first spring 524, and also allow the limit pin 523 and the first tooth under the action of external force. Strip 521 is far away.

In order to realize that one hand can hold the auxiliary push block 525 and the mounting plate 522 at the same time to keep the limit pin 523 away from the rack and move the position of the opening and closing piece 51, which facilitates the operation and realizes that only one hand can be used. The positioning assembly 52 further includes an auxiliary pushing block 525, which is located below the mounting plate 522, the auxiliary pushing block 525 is fixed to the limiting pin 523, and the auxiliary pushing block 525 is parallel to the top of the mounting plate 522.

In order to facilitate the movement of the opening and closing piece 51, the movement of the opening and closing piece 51 can be realized by only dragging the mounting plate 522. A blocking component 53 is installed at the connection between the limit pin 523 and the mounting plate 522, and the blocking component 53 is used to allow or limit the limit. The bit pin 523 is close to the rack.

In order to design the blocking component 53 with a simple structure, the limit pin 523 can be automatically limited after the limit pin 523 is moved and the opening and closing piece 51 is dragged. The blocking component 53 includes: a support plate 531, a rotating rod 532, For the eccentric wheel 533 and the coil spring 534, a rotating rod 532 is mounted on the mounting plate 522, and an eccentric wheel 533 is mounted on the rotating rod 532. The center line of the eccentric wheel 533 and the center line of the rotating rod 532 are not in a straight line. The inner end of the coil spring 534 is fixed to the rotating rod 532, the outer end of the coil spring 534 is fixed to the mounting plate 522, and a support plate 531 is fixed at the top end of the limit pin 523. The eccentric wheel 533 can be maintained under the elastic force of the coil spring 534 to support the support plate 531.

In order to realize that the opening and closing plate 51 automatically closes the discharge pipe 23, the mounting plate 522 is connected to one end of the second spring 54 and the other end of the second spring 54 is fixed to the discharge pipe 23, which can hold the opening and closing plate 51 under the elastic force of the second spring 54 Close the discharge pipe 23.

In order to maintain the stability of the opening and closing piece 51 when the discharge pipe 23 is closed, a release assembly 55 is installed at the blocking assembly 53, and the release assembly 55 is used to make the blocking assembly 53 release the limiting pin 523.

In order to design a simple structure of the release assembly 55, the release assembly 55 includes: a gear 551 and a second rack 552, the gear 551 is fixed to the rotating rod 532, the center line of the gear 551 and the center line of the rotating rod 532 are in a straight line, and The gear 551 engages with a second rack 552. When the opening and closing plate 51 closes the discharge tube 23 under the elastic force of the second spring 54, the second rack 552 acts with the gear 551 to move the eccentric 533 away from the support plate 531.

The working principle of this embodiment: when the opening and closing plate 51 is at the position to close the discharge pipe 23, the second rack 552 restricts the rotation of the gear 551 to keep the coil spring 534 in a deformed state, and the eccentric wheel 533 is away from the support plate 531 , That is, the position of the eccentric wheel 533 does not affect the support plate 531 ascending and descending with the limit pin 523, keeping the limit pin 523 engaged with the first rack 521 under the elastic force of the first spring 524, and the second spring 54 also keeps the opening and closing plate 51 is located at the position where the discharge pipe 23 is closed.

When the discharge pipe 23 is opened for the first time, first, move the auxiliary push block 525 close to the mounting plate 522, and the limit pin 523 separates from the first rack 521, so as to prevent the first rack 521 from restricting the mounting plate 522 and the mounting plate 522 through the limit pin 523. The movement of the opening and closing plate 51 maintains this state; then, the auxiliary push block 525 and the mounting plate 522 are pulled together, so that the opening and closing plate 51 opens the discharge pipe 23. At this time, due to the rotation restriction effect of the rack on the gear 551, rigid When starting to move the opening and closing piece 51, the eccentric wheel 533 will not rotate to the position of the supporting support plate 531, so the limit pin 523 will not be restricted by the eccentric wheel 533. If the subsequent opening and closing piece 51 makes the discharge tube 23 open more Large, under the elastic force of the coil spring 534, the eccentric wheel 533 can be supported under the support plate 531, and the limit pin 523 will not mesh with the first rack 521. Therefore, the gear 551 needs to be manually rotated to make the gear 551 separate from the second rack. The restriction of 552 makes the eccentric wheel 533 deviate from the position of the support plate 531 to release the limiting pin 523, so that the limiting pin 523 clamps the first rack 521 and stabilizes the position of the opening and closing piece 51.

When you finally want to close the opening and closing plate 51, first, you need to rotate the rotating rod so that the eccentric wheel 533 will not hinder the lifting of the limit pin 523 and maintain this state; then, move the auxiliary push block 525 to move the limit pin 523 away The first rack 521; and then, the rotation rod 532 is realized. Under the elastic force of the coil spring 534, the eccentric wheel 533 is in a position to block the limit pin 523, and the limit pin 523 is away from the first rack 521; finally, in the second spring 54 Under elastic force, the opening and closing piece 51 is pulled to close the discharge pipe 23, and the second rack 552 drives the gear 551 to rotate. Because only a small part of the eccentric wheel 533 cannot support the support plate 531, only when the opening and closing piece 51 closes the discharge pipe 23 The eccentric wheel 533 is far away from the support plate 531, and under the elastic force of the first spring 524, the limiting pin 523 engages with the first rack 521 to maintain the position where the opening and closing plate 51 closes the discharge pipe 23.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model and not to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the utility model can be Modification or equivalent replacement of the technical solution does not deviate from the purpose and scope of the technical solution of the present utility model, which shall be covered by the scope of the claims of the present utility model.[Gravimetric blender]
