【Explanation】Stabilizing device of weighing mixer
【Technical Field】
[0001] This utility model relates to a stabilizing device, specifically, a stabilizing device for a weighing mixer.
【Background technique】
[0002] Weighing mixers are used in injection molding and extrusion industries, where a variety of raw materials are required to be accurately mixed in proportion. The mixer itself will vibrate when it is working, and the mixer is generally connected to the machinery used in the next process, so that the vibration generated by these machinery is also transmitted to the mixer through the connected parts, and these vibrations will seriously affect the mixer. The accuracy and stability of the machine weighing, thereby reducing the accuracy of the raw material ratio, will ultimately reduce the quality of the product. The vibration of the mixer itself and the vibration transmitted from other machinery are also very likely to resonate, and the effect of the accuracy of the symmetry will be greater, and it will also produce very loud noise.
Utility model content
[0003] The present utility model is designed for the current mixers that are easily affected by vibration, have poor weighing stability, and inaccurate mixing ratios of raw materials, resulting in reduced product quality, prone to resonance, and noise. Stabilizing device for heavy mixer.
[0004] In the stabilizing device of the weighing mixer of the present invention, weight sensors are symmetrically arranged on the left and right sides of the weighing pan of the mixer, and the two weight sensors are used to support the sidewall of the weighing pan to weigh the weighing pan and its For the contents, the lower part of the weighing pan is connected to the mixing barrel. The contents in the weighing pan can fall into the mixing barrel. The opening at the lower end of the mixing barrel is connected to the suction pipe. A bracket supports the fixed plate, and the stabilizing device includes a shock-absorbing device and a counterweight. A shock-absorbing device is installed between each bracket and the fixed plate. The shock-absorbing device is a rubber shock-absorbing pad and a spring shock-absorbing device. Pads or rubber air springs, counterweights are installed on the side walls of either side of the front and rear sides of the weighing pan.
[0005] The beneficial effect of the present invention is that the stabilizing device of the weighing mixer utilizes the damping device between the bracket and the fixed plate to reduce or even eliminate the vibration of the mixing barrel, thereby reducing and eliminating the vibration of the weighing pan, Avoiding the weighing pan from impacting the weight sensor due to vibration improves the accuracy of weighing, thereby improving the accuracy of the mixing ratio of raw materials in the mixer, ensuring the quality of the final product, and reducing the noise of the equipment. According to the load of the weighing pan and the mixing barrel, the damping device can use spring damping pads, rubber air springs and other elastic structures with a large deformation range and small load capacity, or rubber damping pads with a relatively large deformation range. The elastic structure with small and large load capacity, while ensuring the balance of the center of gravity of the weighing pan and the mixing barrel, buffers vibrations in all directions, ensuring the stability of the weighing pan and maintaining the accuracy of weighing. A counterweight is installed on the weighing pan, and the counterweight is not installed on the side with a weight sensor, so that the counterweight increases the mass of the weighing pan and the mixing barrel as a whole, and changes the resonance point of the weighing pan and the mixing barrel as a whole to avoid occurrence Resonance further ensures weighing accuracy and reduces equipment noise. It also ensures the balance of the overall center of gravity of the weighing pan and the mixing barrel, and avoids re-vibration due to the swing of the entire weighing pan and the mixing barrel due to the deviation of the center of gravity.
[0006] Figure 1 is a structural diagram of a stabilizing device for a weighing mixer.
DETAILED DESCRIPTION [0007] The stabilizing device of the weighing mixer of the present invention, as shown in FIG. 1, is symmetrically provided with weight sensors 2 on the left and right sides of the weighing pan I of the mixer, and two weight sensors 2 Weigh the weighing pan I and its contents by supporting the side wall of the weighing pan I.
[0008] The lower part of the weighing pan 1 is connected to the mixing barrel 3. The contents of the weighing pan 1 can fall into the mixing barrel 3. The opening at the lower end of the mixing barrel 3 is connected to the suction pipe 4, and the lower part of the mixing barrel 3 is arranged horizontally. There is a fixed plate 5, and a plurality of fixed brackets 6 support the fixed plate 5.
[0009] The stabilizing device includes a shock absorbing device 7 and a counterweight 8. A shock absorbing device 7 is installed between each bracket 6 and the fixed plate 5. The shock absorbing device 7 is a rubber shock pad, a spring shock pad or rubber The air spring and the counterweight 8 are installed on the side walls of either side of the front and rear sides of the weighing pan.
[0010] When the mixer is used, first add materials to the weighing pan 1, and obtain the weight of the added materials according to the mass change detected by the weight sensor 2, so as to control the amount of the added materials. Each material is added to the weighing pan I in turn. After all the materials are added, the lower part of the weighing pan I is opened, and all the materials are sent to the mixing tank 3 for stirring and mixing.
[0011] In order to improve production efficiency and enhance the continuity of production, the mixing tank 3 stirs the mixed materials, while the lower part of the weighing pan is closed, and a new batch of materials enters the weighing pan 1 for weighing and batching. After the materials in the mixing barrel 3 are completely stirred and mixed, they are sucked away by the suction pipe 4 from the lower opening. After the materials completely leave the mixing tank 3, the materials in the weighing pan I will enter the mixing tank 3, and the new materials will enter the weighing pan I for batching by weighing.
[0012] The mixing barrel 3 has components for mixing materials by rotation. The suction pipe 4 is suspended due to the high opening position of the mixing barrel 3, and the air drawn from the material also causes the suction pipe 4 to vibrate. Therefore, when the material in the mixing barrel 3 is stirred and when the material is drawn from the mixing barrel 3 by the suction pipe 4, vibration will occur, and the vibration generated by the machine in the next process will also be transmitted through the suction pipe 4. , These vibrations will affect the accuracy of weighing pan I. The damping device 7 located between the support 6 and the fixed plate 5 can reduce or even eliminate these vibrations and ensure the accuracy of weighing pan I. The counterweight increases the overall quality of the weighing pan and the mixing barrel and avoids passing through the suction pipe 4 The transmitted vibration resonates with the overall vibration of the weighing pan and the mixing barrel.
