Manufacturing method of plastic pellet Gravimetric blender
【Technical Field】
[0001] The present invention relates to the technical field of mixer design, in particular to a plastic pellet Gravimetric blender.
【Background technique】
[0002] In the plastic injection molding process, the plastic parts used for injection molding are usually mixed by a variety of plastic pellets of different compositions. In order to ensure that the injection molded plastic parts can achieve the expected physical and chemical properties, it must be based on The production process strictly controls the weight ratio of the different components of the plastic pellets, so the plastic pellets should be weighed before mixing. Since most of the traditional methods use manual weighing, manual weighing will cause various errors. The weight ratio of each component Failure to meet the requirements of the production process results in the injection molded plastic parts not meeting the requirements of the relevant technical standards. Therefore, it is necessary to solve the above-mentioned problems.

[Summary of the invention]

[0003] In order to overcome the shortcomings of the prior art, the present invention provides a plastic pellet Gravimetric blender capable of automatic weighing.
[0004] The technical solutions adopted by the present invention are:

[0005] As an improvement of the above technical solution, the number of the feed hopper is four, and the feed hopper is equipped with a suction machine that supplies material to the feed hopper.
[0006] As a further improvement of the above technical solution, the weighing device includes a weighing container with a weight sensor, a baffle plate is provided at the lower part of the weighing container, and a cylinder is connected to the baffle plate.
[0007] Further, the stirring device includes a stirring barrel and a stirring baffle connected to the stirring barrel, and a rotating shaft with stirring blades is installed in the stirring barrel, and a motor is connected to the rotating shaft.
[0008] Further, an organic seat plate is installed at the upper end of the discharge hopper, and the chassis is fixed on the machine seat plate through a connecting flange.
[0009] Further, the chassis is also provided with a chassis door.
[0010] The beneficial effect of the present invention is: because a weighing device is provided in the cabinet, the weight of the plastic pellets of different components in each hopper can be accurately measured, which improves the accuracy of the distribution ratio of each component in the plastic product, and makes the product The chemical properties of the materials meet the requirements of relevant technical standards to ensure product quality and improve the level of large-scale production of products.
[0011] The present invention will be further described below in conjunction with embodiments.

【Detailed ways】
[0013] The description of this part combined with the attached embodiments is limited to exemplary and explanatory categories. The present invention can also be implemented in other ways different from those described here. Therefore, the scope of protection of the present invention is not disclosed below. Limitations of the embodiment.
[0014] A plastic pellet Gravimetric blender, comprising a chassis 1, a plurality of feed hoppers 2 are installed at the upper end of the chassis 1, a discharge hopper 3 with a foot stand 31 is connected to the lower end of the chassis 1, and an inner cavity of the chassis 1 The upper part of the case 1 is provided with a weighing device for measuring the incoming material of the hopper 2, and the lower part of the inner cavity of the case 1 is provided with a stirring device for mixing plastic pellets. The outer wall of the case 1 is equipped with a weighing device and a stirring device Connected control panel 11.
[0015] Specifically, the number of the feed hopper 2 is four, the feed hopper 2 is equipped with a suction machine 21 that supplies the feed hopper 2, and the feed hopper 2 is provided with a hopper cover 22, and the suction machine 21 is installed on the mounting hole on the hopper cover 22. The suction machine 21 inputs plastic pellets of different compositions into different feeding hoppers 2. The side wall of the feeding hopper 2 is also provided with a window, through which the feeding situation of the plastic pellets can be observed from the outside, so as to adjust the feeding parameters in a timely manner.
[0016] The weighing device includes a weighing container 4 with a weight sensor, the lower part of the weighing container 4 is provided with a baffle plate 42, which is connected with a cylinder 41. The plastic pellets conveyed from the hopper 2 enter the weighing container 4. When the weight reaches a certain set value, the weight sensor will send a feedback signal. Under the instruction of the control panel 11, the air cylinder 41 pushes the baffle plate 42 to open. The plastic pellets enter the mixing tank 5. The weighing device makes it possible to accurately measure the weight of the plastic pellets of different components in each hopper 2 and improve the accuracy of the distribution ratio of each component in the plastic product, so that the chemical properties of the product meet the requirements of relevant technical standards and ensure product quality.
