Description

Technical Field

[0001] This utility model belongs to the field of polymer material processing technology, specifically a pulverizing device for polymer material processing. Background Technology

[0002] Polymer materials are materials based on polymer compounds. They are materials composed of compounds with relatively high molecular weights, including rubber, plastics, fibers, coatings, adhesives, and polymer-based composites. Polymers are a form of life. Polymer materials include plastics, rubber, fibers, films, adhesives, and coatings. Among them, plastics, synthetic fibers, and synthetic rubber, known as the three major modern synthetic polymer materials, have become essential materials for national economic construction and people's daily lives. In the production and processing of polymer materials, raw materials need to be crushed by crushing equipment. Existing crushing equipment easily generates a large amount of heat when crushing polymer materials. If heat dissipation is not provided, the polymer materials are prone to thermal melting, causing the molten polymer materials to adhere to the crushing blades, affecting the crushing and cutting capabilities. Summary of the Invention

[0003] To overcome the above-mentioned defects, this utility model provides a crushing device for processing polymer materials, which solves the problem that the crushing device easily generates a lot of heat when crushing polymer materials. If the polymer materials are not cooled, they are prone to thermal melting, and the molten polymer materials adhere to the crushing blades, affecting the crushing and cutting of polymer materials.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a pulverizing device for processing polymer materials, comprising a pulverizing chamber, a first motor mounted on the top of one side of the pulverizing chamber, a transmission belt structure provided through the output shaft of the first motor, two cams mounted on the transmission belt structure passing through the pulverizing chamber, six sliding rods fixedly connected to the top of the pulverizing chamber, a first spring provided at the bottom of each sliding rod, the same movable frame slidably connected to the six sliding rods, the first springs connected to the movable frame, a processing cylinder fixedly connected below the movable frame, two ventilation screens installed outside the processing cylinder, a ventilation frame provided on one side of the pulverizing chamber, a fan fixedly connected inside the ventilation frame, and an exhaust screen installed on the side of the pulverizing chamber away from the ventilation frame.

[0005] As a further embodiment of this utility model: a feed pipe is installed on the crushing box, and a second motor is fixedly connected to the top of the crushing box. The second motor is equipped with a transmission rod through its output shaft.

[0006] As a further embodiment of this utility model: several crushing blades are installed on the surface of the transmission rod that passes through the crushing box and is located inside the processing cylinder, and a crushing seat is provided at the bottom of the transmission rod.

[0007] As a further embodiment of this utility model: a through groove is provided on one side of the crushing box, and two mounting frames are fixedly connected to the inner wall of the crushing box, with several limiting rods installed between the mounting frames.

[0008] As a further embodiment of this utility model: a placement frame is slidably connected to the limiting rod, and second springs are respectively installed on the surfaces of the limiting rod on both sides of the placement frame.

[0009] As a further embodiment of this utility model: a screening plate is slidably connected to the inner wall of the placement frame, and a collection box is provided at the bottom of the crushing box.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This pulverizing device for processing polymer materials comprises a first motor, a cam, a fan, and a ventilation screen. The first motor drives the cam to rotate via a transmission belt structure, causing the cam on the movable frame to press against the movable frame. This causes the movable frame to move the processing cylinder up and down outside the slide rod, thereby moving the polymer material inside the processing cylinder and allowing the crushing blades to cut it. Simultaneously, the fan drives air to flow into the processing cylinder, allowing the air to pass through the ventilation screen outside the processing cylinder and enter the cylinder to dissipate heat from the moving polymer material, preventing the polymer material from melting and adhering to the crushing blades, thus ensuring the device's pulverizing efficiency for polymer materials.

[0012] This crushing device for processing polymer materials incorporates a transmission belt structure, a screening plate, a limiting rod, and a second spring. A first motor drives the transmission belt structure via its output shaft, which in turn drives a cam on a placement frame to rotate. The cam continuously presses against the placement frame, causing the placement frame to push against the second spring outside the limiting rod and rebound. This causes the placement frame to vibrate the screening plate, which in turn screens the crushed polymer material, thus improving the crushing quality of the device. Attached Figure Description

[0017] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0018] like Figure 1-3 As shown, this utility model provides a technical solution: a crushing device for processing polymer materials, including a crushing box 1, a feeding pipe 13 installed on the crushing box 1, a second motor 14 fixedly connected to the top of the crushing box 1, a transmission rod 15 set on the output shaft of the second motor 14, and by setting the feeding pipe 13, the raw material can be directly introduced into the processing cylinder 8 for crushing and processing by pouring the raw material into the feeding pipe 13.

[0019] The transmission rod 15 passes through the crushing box 1 and is mounted on the surface inside the processing cylinder 8. Several crushing blades 16 are installed on the surface. A crushing seat 17 is provided at the bottom of the transmission rod 15. By setting the crushing seat 17, the transmission rod 15 can drive the crushing blades 16 to crush the raw materials inside the processing cylinder 8, while the transmission rod 15 can drive the crushing seat 17 to rotate, thereby realizing the grinding of the raw materials, refining the crushing and grinding process, and improving the fineness of the raw materials.

[0020] A through groove 18 is provided on one side of the crushing box 1. Two mounting frames 19 are fixedly connected to the inner wall of the crushing box 1. Several limiting rods 20 are installed between the mounting frames 19. By setting the limiting rods 20, when the cam 4 drives the placement frame 21 to move, the placement frame 21 slides outside the limiting rods 20, so that the limiting rods 20 can limit the placement frame 21.

[0021] A placement frame 21 is slidably connected to the outside of the limiting rod 20. Second springs 22 are respectively installed on the surfaces of the limiting rod 20 on both sides of the placement frame 21. A screening plate 23 is slidably connected to the inner wall of the placement frame 21. A collection box 24 is set at the bottom of the crushing box 1. By setting the collection box 24, the processed polymer material can be collected, which facilitates the unified handling of the polymer material.

[0022] A first motor 2 is installed on the top side of the crushing box 1. The first motor 2 is equipped with a transmission belt structure 3 through the output shaft. The transmission belt structure 3 passes through the crushing box 1 and is equipped with two cams 4. Six slide rods 5 are fixedly connected to the top inside the crushing box 1. By setting the slide rods 5, when the first motor 2 drives the cams 4 to rotate and drive the movable frame 6 to move, the slide rods 5 can limit the movement of the movable frame 6.

[0023] Each slide bar 5 has a first spring 7 at its bottom. The six slide bars 5 are slidably connected to the same movable frame 6. The first spring 7 is connected to the movable frame 6. A processing cylinder 8 is fixedly connected to the bottom of the movable frame 6. Two ventilation screens 9 are installed on the outside of the processing cylinder 8. A ventilation frame 10 is provided on one side of the crushing box 1. A fan 11 is fixedly connected inside the ventilation frame 10. An air outlet screen 12 is installed on the side of the crushing box 1 away from the ventilation frame 10. By setting the ventilation frame 10, the ventilation frame 10 can ensure the normal circulation of air between the inside of the crushing box 1 and the outside, thereby facilitating the fan 11 to drive the airflow for heat dissipation.

[0024] The working principle of this utility model is as follows:

[0025] In operation, the raw material is poured into the feed pipe 13, allowing it to enter the processing cylinder 8. The first motor 2 is then started, driving the transmission belt structure 3 via its output shaft. This causes the two cams 4 on one side of the transmission belt structure 3 to rotate together. The upper cam 4 presses against the movable frame 6, causing it to move downwards and compress the first spring 7, generating a relative elastic force. This elastic force then causes the movable frame 6 to shake, which in turn causes the processing cylinder 8 to shake. The raw material inside the processing cylinder 8 moves with the shaking of the cylinder 8. The second motor 14 is then started, allowing the raw material to move within the processing cylinder 8. The second motor 14 can drive the crushing blades 16 and the crushing seat 17 outside the transmission rod 15 to crush the raw materials. At the same time, the blower 11 is started, which drives the air to flow into the processing cylinder 8. The air passes through the ventilation net 9 to dissipate heat inside the processing cylinder 8. The crushed raw materials in the processing cylinder 8 fall onto the screening plate 23. The transmission belt structure 3 drives the cam 4 below to squeeze the placement frame 21, causing the placement frame 21 to move down and squeeze the second spring 22. The second spring 22 drives the screening plate 23 to vibrate through the placement frame 21 to screen the raw materials. The screened raw materials fall into the collection box 24, completing the crushing process of the raw materials.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
