[0002] Utility model patent CN217189913U discloses a raw material crusher for preparing polyvinyl chloride paste resin, specifically relating to the field of raw material crushers. The invention includes a housing. This utility model, by incorporating a ring plate, locking blocks, locking grooves, recesses, and buffer pads, facilitates the connection between the inner wall of the ring plate and the outer wall of the connecting column. The connection continues until the locking block at the bottom of the ring plate engages with the corresponding locking groove at the top of the top plate. The invention also includes a slider, sliding groove, adhesive plate, locking column, and limiting groove. This allows the slider, fixedly connected to the bottom of the adhesive plate, to move with the corresponding sliding groove at the top of the ring plate, enabling the adhesive plate to move at the top of the ring plate until one side of the adhesive plate is tightly fitted against the outer wall of the connecting column. This effectively improves the stability of the ring plate and connecting column installation, enhancing the stability of the connection column and top plate installation during the raw material crushing process inside the connecting column.

[0003] However, the device lacks a screening function, resulting in a large difference in the size of the pulverized particles. At the same time, raw materials will stick to the pulverizing rod during the pulverizing process, affecting the pulverizing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a polytetrafluoroethylene propylene resin raw material pulverizer with a screening function, which solves the problems of the lack of screening function in the device, resulting in large differences in particle size after pulverization, and the fact that raw materials adhere to the pulverizing rod during the pulverization process, affecting the pulverization efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a poly(fluoroethylene propylene) resin raw material pulverizer with screening function, comprising a shell, a pulverizing roller rotatably connected inside the shell, a motor fixedly installed at the front end of the shell, the output end of the motor passing through the shell and rotatably connected to the shell, the output end of the motor being fixedly connected to the pulverizing roller, a cleaning mechanism provided on the shell, a filter cover slidably connected inside the shell, a baffle bar fixedly connected inside the shell and in contact with the filter cover, and a vibration mechanism provided on the shell.

[0006] Preferably, the cleaning mechanism includes a motor, which is fixedly connected to the housing. The motor's shaft passes through the housing and is rotatably connected to it. A screw is fixedly connected to the rear end of the motor's shaft, and the screw is rotatably connected to the housing. A connecting block is threadedly connected to the outer side of the screw. A sliding plate is fixedly connected to the surface of the connecting block and slidably connected to the housing. A square rod is slidably connected inside the sliding plate. A support plate is fixedly connected to the upper end of the square rod. A spring is provided on the outer side of the square rod. A scraper is fixedly connected to the upper end of the support plate and slidably connected to the crushing roller. The motor drives the screw to rotate and the connecting block to perform threaded movement, thereby causing the sliding plate to move and driving the scraper to move back and forth, scraping and cleaning the groove of the crushing roller to ensure the crushing effect of the crushing roller. At the same time, the elasticity of the spring allows the scraper to move up and down, avoiding interference with the rotation of the crushing roller.

[0007] Preferably, one end of the spring is fixedly connected to the slide plate, and the other end of the spring is fixedly connected to the support plate. By providing the spring, the support plate can be easily reset.

[0008] Preferably, the vibration mechanism includes a servo motor. The servo motor is fixedly mounted on the right end of the housing. The drive shaft of the servo motor passes through the housing and is rotatably connected to it. A slide block is fixedly connected to the left end of the servo motor. A top block is slidably connected inside the slide block, and a compression spring is provided inside the slide block. By driving the slide block to rotate through the servo motor, the top block rotates and collides with the filter cover, allowing the filter cover to slide inside the housing. This allows the filter cover to sieve the pulverized polytetrafluoroethylene propylene resin while preventing filter cover clogging.

[0009] Preferably, a sliding pin is fixedly connected to the surface of the top block, and the sliding pin is slidably connected to the slide block. The sliding pin guides the movement of the top block.

[0010] Preferably, one end of the compression spring is fixedly connected to the slide, and the other end of the compression spring is fixedly connected to the top block. By setting the compression spring, the top block can automatically extend and retract within the slide.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses an electric motor to drive the screw to rotate and the connecting block to make a threaded movement, which in turn causes the sliding plate to move and drive the scraper to move back and forth, scraping and cleaning the inside of the crushing roller groove to ensure the crushing effect of the crushing roller. At the same time, through the elastic action of the spring, the scraper can move up and down to avoid interfering with the rotation of the crushing roller.

[0013] 2. This utility model uses a servo motor to drive the slide to rotate, which in turn causes the top block to rotate and collide with the filter cover, allowing the filter cover to slide inside the housing. This allows the filter cover to screen the crushed polytetrafluoroethylene propylene resin while preventing the filter cover from clogging. Attached Figure Description

The shaft of the motor 41 passes through the housing 1 and is rotatably connected to it. A screw 42 is fixedly connected to the rear end of the shaft of the motor 41. The screw 42 is rotatably connected to the housing 1. A connecting block 43 is threadedly connected to the outside of the screw 42. A sliding plate 44 is fixedly connected to the surface of the connecting block 43. The sliding plate 44 is slidably connected to the housing 1. A square rod 45 is slidably connected inside the sliding plate 44. A support plate 46 is fixedly connected to the upper end of the square rod 45. A spring 47 is provided on the outside of the square rod 45. One end of the spring 47 is connected to the sliding plate 44. The spring 47 is fixedly connected to the other end of the support plate 46. The spring 47 makes it easy for the support plate 46 to reset. The upper end of the support plate 46 is fixedly connected to the scraper 48, which is slidably connected to the crushing roller 2. The motor 41 drives the screw 42 to rotate and the connecting block 43 to make threaded movement, which in turn causes the slide plate 44 to move and drive the scraper 48 to move back and forth, scraping and cleaning the inside of the crushing roller 2, ensuring the crushing effect of the crushing roller 2. At the same time, the elasticity of the spring 47 allows the scraper 48 to move up and down, avoiding interference with the rotation of the crushing roller 2.

This allows the filter cover 5 to screen the pulverized polytetrafluoroethylene propylene resin while preventing the filter cover 5 from clogging.

[0023] The specific implementation process of this utility model is as follows: In use, polytetrafluoroethylene propylene resin is placed into the outer casing 1. The motor 3 is started, driving the crushing roller 2 to rotate, causing the crushing roller 2 to crush the polytetrafluoroethylene propylene resin. Then, the motor 41 is started, driving the screw 42 to rotate and the connecting block 43 to perform threaded movement, thereby causing the sliding plate 44 to move, driving the scraper 48 to move back and forth, scraping and cleaning the inside of the crushing roller 2's groove, ensuring the crushing effect of the crushing roller 2. Simultaneously, through the elastic action of the spring 47... This allows the scraper 48 to move up and down, avoiding interference with the rotation of the crushing roller 2. The crushed polytetrafluoroethylene propylene resin falls onto the filter cover 5, where it is screened and filtered.
