Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic production, in particular to a raw material batching device for plastic production. Background Art
[0002] Plastics are not pure substances but rather a combination of many materials. Polymers (also known as synthetic resins) are the primary component of plastics. To improve the properties of plastics, various auxiliary materials are added to the polymers, such as fillers, plasticizers, lubricants, stabilizers, and colorants. Raw material batching equipment plays a crucial role in the plastics production process. These devices not only ensure the accurate proportions of raw materials but also directly impact product quality and production efficiency.
[0003] Some existing batching devices lack stirring and mixing functions when in use and can only realize the automatic feeding function. They are unable to mix the raw materials during the feeding process, which easily leads to uneven distribution of the raw materials in subsequent processing and affects product quality.
[0004] For example, the patent publication number CN217276471U discloses an automatic batching and weighing device for plastic raw materials. The patented automatic batching and weighing device for plastic raw materials can quickly weigh the plastic raw materials by setting a weighing sensor and a display screen. Then, by setting a feed pipe and a conveyor belt, it is conducive to feeding the plastic raw materials after the batching and weighing is completed. There is no need for manual batching and weighing, the weighing accuracy is controllable, the operation is simple, and it is more convenient to use.
[0005] The patented automatic batching and weighing device for plastic raw materials demonstrates high efficiency and accuracy in automatic batching and weighing. However, after the device transports the plastic raw materials from the storage box through the discharge pipe to the conveyor belt, it only realizes the automatic feeding function, but does not include a mechanism for stirring and mixing the raw materials. This means that if the batching requires the mixing of multiple raw materials, the device cannot directly complete the mixing process, which may cause the raw materials to be unevenly distributed in subsequent processing, affecting product quality.
[0006] Therefore, it is necessary to invent a raw material batching device for plastic production to solve the above problems. Utility Model Content

A sinking trough is provided on the top of the workbench 1, and the conveyor 4 is installed on the top of the sinking trough. The mixing mechanism 3 includes a No. 1 support frame 5, which is mounted above the workbench 1, and the bottom of the No. 1 support frame 5 is fixedly connected to the workbench 1. A driving motor 6 is installed on the top of the No. 1 support frame 5, and a loading seat 7 is rotatably connected to the top surface of the No. 1 support frame 5. The output shaft of the driving motor 6 is transmission-connected to the loading seat 7, and a No. 1 electric push rod 17 is installed at the bottom of the loading seat 7, and a sealing cover 8 is installed at the bottom of the No. 1 electric push rod 17. A stirring shaft 9 is installed at the bottom of the sealing cover 8, and a stirring blade 10 is installed on the surface of the stirring shaft 9.
[0036] In one aspect of this embodiment, the feeding mechanism 2 includes a second support frame 11, a storage tank 12 is installed in the middle of the second support frame 11, the bottom discharge port of the storage tank 12 is a funnel-shaped structure, and a spiral weighing feeder 13 is installed at the bottom discharge port of the storage tank 12. The output end of the spiral weighing feeder 13 extends above the conveyor 4, and a limiting mechanism is installed on the top of the conveyor 4. The number of limiting mechanisms is set to multiple, and the multiple limiting mechanisms all extend to the surface of the conveyor 4. Each limiting mechanism is composed of two clamping components. The two clamping assemblies are symmetrically arranged. The clamping assembly includes a No. 2 electric push rod 14 and an arc-shaped clamping plate 15. The No. 2 electric push rod 14 is installed on the surface of the conveyor 4. The arc-shaped clamping plate 15 is installed on the working end of the No. 2 electric push rod 14. The clamping surface of the arc-shaped clamping plate 15 is installed with a rubber anti-slip pad. A temporary storage tank 16 is provided on the top of the conveyor 4. The temporary storage tank 16 is located between the two clamping assemblies. The diameter of the sealing cover 8 is equal to the outer diameter of the temporary storage tank 16. The distance from the stirring blade 10 to the stirring shaft 9 is less than the inner radius of the temporary storage tank 16.
[0037] Working principle of this utility model:
[0038] Refer to the instruction manual Figure 1-6 When using the utility model, first place the empty temporary storage tanks 16 one by one on the conveyor 4, ensuring that each temporary storage tank 16 is accurately located between the two clamping components, and push the arc-shaped clamping plate 15 toward the middle through the second electric push rod 14 on the conveyor 4 until the arc-shaped clamping plate 15 tightly clamps the temporary storage tank 16, and use the rubber anti-slip pad to increase the stability and anti-slip properties of the clamping;
[0039] Start the conveyor 4 and drive the temporary storage tank 16 forward at an appropriate speed. When the temporary storage tank 16 moves to the bottom of the output end of the screw weigh feeder 13 of the first feeding mechanism 2, start the screw weigh feeder 13. Through its precise control, the raw materials in the storage tank 12 are discharged according to the set amount and accurately fall into the temporary storage tank 16.
[0040] As the conveyor 4 continues to move the temporary storage tank 16, when the temporary storage tank 16 reaches the bottom of the first mixing mechanism 3, the No. 1 electric push rod 17 starts to work, pushing the stirring shaft 9 and the stirring blade 10 down into the temporary storage tank 16 until the blocking cover 8 completely covers the top opening of the temporary storage tank 16. At the same time, the drive motor 6 is started, driving the loading base 7, the No. 1 electric push rod 17, the stirring shaft 9 and the stirring blade 10 to rotate together, and the stirring blade 10 fully mixes the raw materials inside the temporary storage tank 16;
[0041] During this mixing process, the next temporary storage tank 16 receives new raw materials at the previous feeding mechanism 2, realizing continuous operation. After the mixing reaches the predetermined time, the driving motor 6 is stopped, the No. 1 electric push rod 17 returns to its original position, the stirring shaft 9 and the stirring blade 10 are withdrawn from the temporary storage tank 16, and the conveyor 4 continues to drive the temporary storage tank 16 where the mixed raw materials are located to move forward and enter the next process;
[0042] Repeat the above steps, that is, the conveyor 4 drives the temporary storage tank 16 to pass through the subsequent feeding mechanism 2 and mixing mechanism 3 in sequence, receiving a fixed amount of raw materials each time it reaches the feeding mechanism 2, and mixing them when it reaches the mixing mechanism 3. In this way, it can be ensured that sufficient stirring is carried out after each addition of new raw materials, thereby achieving uniform mixing of multiple raw materials, which is beneficial to improving the quality and production efficiency of plastic products.
