It has poor stability to light and heat, no fixed melting point, good mechanical properties, and excellent dielectric properties. PVC is widely used in building materials, industrial products, and daily necessities. During the production of PVC, the raw materials required for production need to be crushed by a crushing device.

[0003] Patent document CN221288033U discloses a raw material crushing device for polyvinyl chloride production. It discloses that "when the hydraulic cylinder of this utility model drives the toothed plate to rise and fall and mesh with the gear, the gear can mesh with the rack, which can drive the rotating plate and the arc plate to rotate. The arc plate will drive the coarse screen or the fine screen to rotate, so that the coarse screen or the fine screen is located at the feed inlet. The coarse screen or the fine screen can be used for screening as needed. There is no need to disassemble the unused screen and then install the required screen, which is more convenient, saves time and effort, and improves work efficiency."

[0004] However, the crushing devices in the aforementioned published documents mainly consider existing crushing devices, which are not convenient for screening raw materials. However, after crushing the raw materials, the crushing equipment cannot guarantee the quality of the crushed materials. If the crushed materials stick together, it will affect the crushing quality.

[0005] In view of this, it is necessary to develop a raw material crushing device for polyvinyl chloride production, which can beat the crushed raw materials to prevent them from sticking together after being discharged. Utility Model Content

[0022] Please see Figure 1 , Figure 2 and Figure 3 A raw material crushing device for polyvinyl chloride production;

[0023] The system includes: a support base 1 and a crushing assembly. The crushing assembly is mounted on the top of the support base 1. The crushing assembly is used to break up the raw materials that have adhered together after crushing. The crushing assembly includes a crushing box 3, a first motor 5, a rotating shaft 6, and a crushing plate 7. The crushing box 3 is mounted on the top of the support base 1. The first motor 5 is mounted on the front of the crushing box 3. The rotating shaft 6 is mounted inside the crushing box 3, and one end of the rotating shaft 6 is connected to the first motor 5. The crushing plate 7 is mounted on the outside of the rotating shaft 6. An inlet 4 is provided on the top of the crushing box 3, and the bottom of the crushing box 3... The discharge shell 8 is installed through the support base 1. The bottom of the discharge shell 8 is installed with the discharge port 9. The support legs 2 are symmetrically installed at the bottom of the support base 1. The crushing box 3 is installed with the crushing box 10 on top. The crushing shaft 11 is symmetrically installed inside the crushing box 10. The front of the crushing box 10 is installed with the gear box 12. The gear 12 is meshed with the transmission gear 13 inside the gear box 12. The transmission gear 13 is connected to the crushing shaft 11. The front of the gear box 12 is installed with the second motor 14, and the output end of the second motor 14 is connected to the transmission gear 13.

[0024] The support base 1 is used to support the crushing component. When the crushed raw material enters the crushing box 3 through the inlet 4, the first motor 5 is started by the controller. After being powered on, the first motor 5 converts electrical energy into kinetic energy, thereby driving the rotating shaft 6 at the output end to rotate. This causes the multiple crushing plates 7 installed on the outside of the rotating shaft 6 to rotate, so that the raw material entering the crushing box 3 can be separated after being hit by the crushing plates 7, ensuring the crushing quality of the raw material. The crushed raw material falls into the discharge shell 8 and is finally discharged through the discharge port 9. Before the raw material enters the crushing box 3, it will first enter the crushing box 10. The second motor 14 drives the transmission gear 13 in the gearbox 12 to rotate, thereby causing the crushing shaft 11 installed inside the crushing box 10 to rotate relative to it. When rotating, the crushing shaft 11 crushes and cuts the raw material.

[0025] Please see Figure 1 and Figure 4 A raw material crushing device for polyvinyl chloride production;

[0026] The crushing box 10 includes a feed inlet 15 and a water tank 19. The feed inlet 15 is installed on the top of the crushing box 10. The top of the feed inlet 15 is installed with a mounting shell 16. The inside of the mounting shell 16 is installed with a fixing pipe 17. The bottom of the fixing pipe 17 is installed with multiple atomizing nozzles 18, and the atomizing nozzles 18 penetrate the top inner wall of the feed inlet 15. The top of the support base 1 is installed with a water tank 19, and the water tank 19 is located on one side of the crushing box 3. The top of the water tank 19 is installed with a transfer pump 20. The output end of the transfer pump 20 is installed with a transfer pipe 21, and one end of the transfer pipe 21 is connected to the fixing pipe 17.

[0027] The feed inlet 15 provides space for the raw materials to enter the interior of the crushing chamber 10. The mounting shell 16 is used to install the fixing pipe 17 and the atomizing nozzle 18, so that the atomizing nozzle 18 can penetrate through the top of the feed inlet 15. The feed inlet 15 provides space for the raw materials to enter the interior of the device. The liquid in the water tank 19 is drawn by the transfer pump 20 and enters the fixing pipe 17 through the transfer pipe 21. Finally, it is sprayed out through the atomizing nozzle 18. The atomized liquid sprayed by the atomizing nozzle 18 makes the surface of the raw materials have water mist, thereby avoiding a large amount of dust from being scattered during the crushing of the raw materials and causing pollution to the working environment.

[0028] The working principle is as follows: First, the device is supported in the required position by the support leg 2. The raw material to be crushed enters the device through the feed port 15. When the raw material enters, water mist is sprayed onto the surface of the raw material through the atomizing nozzle 18 to prevent dust from scattering during crushing. The raw material enters the crushing chamber 10 and is crushed by the rotation of the crushing shaft 11. The crushed raw material enters the crushing chamber 3, where the first motor 5 drives the crushing plate 7 to rotate, so that the raw material that sticks together after crushing can be completely dispersed, making the crushing quality of the device higher.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
