Description

Technical Field

[0001] This utility model relates to the field of pelletizing and crushing machines, and in particular to a PVC particle pelletizing and crushing machine. Background Technology

[0002] The pelletizer is used to pelletize larger PVC particles. It consists of a machine body, feed inlet, crushing rollers, blades, belts, pulley sets, gears, motor, and discharge outlet. When using the pelletizer, the operator starts the motor, which rotates the first pulley. Through belt drive, the second pulley rotates, which in turn rotates the crushing rollers. With the help of a pair of gears, both crushing rollers rotate. The operator pours larger PVC particles into the feed inlet of the machine body, where they are crushed by the blades on the crushing rollers. The operator sets up a collection box at the discharge outlet to collect the crushed PVC particles.

[0003] The inventors discovered in their daily work that some pelletizers do not completely crush PVC particles, causing some PVC particles to fall into the collection box along with the crushed PVC particles without being crushed. In order to crush the incompletely crushed PVC particles a second time, all the PVC in the collection box is poured in for further crushing. This means that the PVC particles that were originally crushed have to be crushed again, which may result in low PVC particle crushing efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in actual use, some pelletizers do not completely crush PVC particles, causing some PVC particles to fall into the collection box without being crushed. In order to re-crush the incompletely crushed PVC particles, all the PVC in the collection box is poured in for re-crushing, which means that the originally completely crushed PVC particles have to be crushed again, which may result in low PVC particle crushing efficiency. Therefore, a PVC particle pelletizer is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a PVC particle pelletizing and crushing machine, comprising a machine body, an inlet fixedly connected to the upper end of the machine body, a screening component provided at the left end of the machine body, a second pulley provided on the front side of the machine body, a motor installed on one side of the machine body, a first pulley fixedly connected to the output end of the motor, a belt provided between the first pulley and the second pulley, a crushing roller rotatably connected to the inner wall of the machine body, the crushing roller being fixedly connected to the second pulley, a protective component, an outlet, and a gear provided on one side of the machine body, the gear being fixed to the crushing roller, the gears on both sides meshing, the screening component including a screen slidably inserted into one side of the machine body, a pull plate slidably inserted into the inner wall of the machine body, a sealing plate inserted into the left end of the machine body, the surface of the sealing plate having protrusions, a connecting rod fixedly connected between the pull plate and the sealing plate, and a handle fixedly connected to the left end of the sealing plate.

[0006] The effect achieved by the above components is as follows: After the PVC particles are crushed by the blades on the crushing roller, they fall onto the screen. Through the swinging mechanism, the screen swings left and right, so that the PVC particles that meet the crushing standard fall out of the screen, while the PVC particles that are not completely crushed remain on the screen. Then, the worker pulls the handle, which pulls the sealing plate and the pull plate connected to the connecting rod, thereby scraping out the PVC particles that are not completely crushed on the screen. The worker collects them in a box, so that only these PVC particles that are not completely crushed need to be crushed again. The PVC particles that are completely crushed are sent to the next process, thereby maximizing the efficiency of PVC particle crushing.

[0007] Preferably, a slide rod is slidably inserted into the left end of the machine body, the two ends of the slide rod are fixed to the screen, a fixing block is fixedly connected to the arc surface of the slide rod, a rotating roller is rotatably connected to the front of the fixing block, a drive groove is opened at the left end of the machine body, and a push plate is slidably connected to the inner wall of the drive groove.

[0008] The effect achieved by the above components is as follows: the push plate in the drive groove moves up and down through the drive mechanism, which pushes the rotating roller on the fixed block, thereby pushing the screen connected to the slide bar. With the cooperation of the reset mechanism, the screen swings left and right.

[0009] Preferably, a return spring is fixedly connected to one side of the screen, the other end of the return spring is fixed to the machine body, and the return spring is sleeved on the slide rod.

[0010] The effect achieved by the above components is to reset the screen by setting a reset spring.

[0011] Preferably, a lead screw is rotatably connected to the inner wall of the drive groove, the lead screw is threadedly connected to the push plate, and the lead screw is driven to rotate by an external motor.

[0012] The effect achieved by the above components is to connect the lead screw to an external motor, allowing it to continuously rotate in both directions, thereby causing the push plate in the drive slot to move up and down.

[0013] Preferably, the protective component includes a mounting frame fixedly connected to the left end of the machine body, and a protective cover is inserted into the left end of the mounting frame.

[0014] The effect achieved by the above components is that the protective cover is inserted into the mounting frame, and the inner wall of the mounting frame is provided with protrusions to fix the protective cover, thereby preventing workers from being accidentally injured by gears when collecting PVC particles.

[0015] Preferably, the inner wall of the mounting frame is slidably connected to an insert block, the insert block is inserted into the protective cover, and the upper end of the insert block is fixedly connected to an operating rod, the operating rod being slidably inserted into the mounting frame.

[0016] The effect achieved by the above components is that the worker drags the operating lever to insert the plug into the protective cover, thereby further fixing the protective cover.

[0017] Preferably, an auxiliary spring is fixedly connected to the lower end of the operating lever, and the other end of the auxiliary spring is fixed to the mounting frame.

[0018] The effect achieved by the above components is that by setting an auxiliary spring, the auxiliary spring pulls the operating rod, thereby assisting in limiting the operation rod.

[0019] Preferably, one side of the insert block has an inclined surface.

[0020] The effect achieved by the above components is that, by setting the inclined surface, the auxiliary insert block is inserted into the protective cover.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] In this invention, by setting up a screening component, after PVC particles are crushed by the blades on the crushing roller, they fall onto the screen. Through a swinging mechanism, the screen swings left and right, so that PVC particles that meet the crushing standard fall out of the screen, while incompletely crushed PVC particles remain on the screen. Then, the worker pulls the handle, which pulls the sealing plate and the connecting plate connected to the connecting rod, thereby scraping out the incompletely crushed PVC particles from the screen. The worker collects them in a box, so that only these incompletely crushed PVC particles need to be crushed again. The fully crushed PVC particles are sent to the next process, thus maximizing the PVC particle crushing efficiency. This solves the problem that some pelletizers do not completely crush PVC particles, causing some PVC particles to fall into the collection box without being crushed. In order to crush the incompletely crushed PVC particles again, all the PVC in the collection box is poured in for re-crushing, which means that the originally fully crushed PVC particles need to be crushed again, which may result in low PVC particle crushing efficiency.

A handle is fixedly connected to the left end of the sealing plate 23. By setting the screening component 2, after the PVC particles are crushed by the blades on the crushing roller 10, they fall onto the screen 21. Through the swinging mechanism, the screen 21 swings left and right, so that the PVC particles that meet the crushing standard fall out of the screen 21, while the PVC particles that are not completely crushed remain on the screen 21. Then, the worker pulls the handle, so that the sealing plate 23 is pulled, and the pull plate 22 connected to the connecting rod 24 is pulled, thereby scraping out the PVC particles that are not completely crushed on the screen 21. The worker collects them in a box, so that only these PVC particles that are not completely crushed need to be crushed again. The completely crushed PVC particles are sent to the next process, thereby maximizing the PVC particle crushing efficiency. Functionally, a slide rod 25 is slidably inserted into the left end of the machine body 1. Both ends of the slide rod 25 are fixed to the screen 21. A fixing block 29 is fixedly connected to the arc surface of the slide rod 25. A rotating roller 210 is rotatably connected to the front of the fixing block 29. A drive groove 26 is opened at the left end of the machine body 1. A push plate 28 is slidably connected to the inner wall of the drive groove 26. Through a drive mechanism, the push plate 28 in the drive groove 26 moves up and down, pushing the rotating roller 210 on the fixing block 29, thus pushing the screen 21 connected to the slide rod 25. This is coordinated with a reset mechanism. The screen 21 swings left and right. A return spring 211 is fixedly connected to one side of the screen 21, and the other end of the return spring 211 is fixed to the machine body 1. The return spring 211 is sleeved on the slide rod 25. By setting the return spring 211, the screen 21 is reset. The inner wall of the drive groove 26 is rotatably connected to the lead screw 27. The lead screw 27 is threadedly connected to the push plate 28. The lead screw 27 is driven to rotate by an external motor. By connecting the lead screw 27 to the external motor, it can be continuously rotated in both directions, causing the push plate 28 in the drive groove 26 to move up and down.

[0032] Reference Figure 5As shown in this embodiment: the protective component 3 includes a mounting frame 31 fixedly connected to the left end of the machine body 1. A protective cover 32 is inserted into the left end of the mounting frame 31. The protective cover 32 is inserted into the mounting frame 31. The inner wall of the mounting frame 31 is provided with protrusions to fix the protective cover 32, thereby preventing workers from being accidentally injured by the gear 11 when collecting PVC particles. An insert block 33 is slidably connected to the inner wall of the mounting frame 31. The insert block 33 is inserted into the protective cover 32. An operating rod 34 is fixedly connected to the upper end of the insert block 33. 4. The sliding installation frame 31 is used. The worker drags the operating rod 34 so that the insert block 33 is inserted into the protective cover 32, thereby further fixing the protective cover 32. An auxiliary spring 35 is fixedly connected to the lower end of the operating rod 34. The other end of the auxiliary spring 35 is fixed to the installation frame 31. By setting the auxiliary spring 35, the auxiliary spring 35 pulls the operating rod 34, thereby assisting in limiting the operation rod 34. A slope 36 is opened on one side of the insert block 33. By setting the slope 36, the auxiliary insert block 33 is inserted into the protective cover 32.

[0033] Working principle:

[0034] When using the pelletizer, the worker starts the motor 5, causing the first pulley 6 to rotate. This, via the belt 8, drives the second pulley 7, which in turn rotates the crushing roller 10. A pair of gears 11 further rotates both crushing rollers 10. Larger PVC particles are then fed into the machine body 1 through the inlet 4 and crushed by the blades on the crushing rollers 10. A collection box at the outlet 9 collects the crushed PVC particles. After being crushed by the blades on the crushing rollers 10, the particles fall onto the screen 21. The lead screw 27 is connected to an external motor, causing it to rotate continuously in both directions. This moves the push plate 28 in the drive groove 26 up and down, pushing the rotating roller 210 on the fixed block 29. This pushes the screen 21, connected to the slide rod 25. A return spring 211 resets the screen 21, causing it to swing left and right. This swinging motion allows the PVC particles that have reached the required crushing standard to fall out of the screen 21. Incompletely crushed PVC particles remain on the screen 21. The worker then pulls the handle, causing the sealing plate 23 to move, which in turn moves the pull plate 22 connected to the connecting rod 24, scraping out the incompletely crushed PVC particles from the screen 21. The worker collects these particles in a box, thus only needing to crush them again. The fully crushed PVC particles are sent to the next process, thereby maximizing the crushing efficiency of PVC particles. The protective cover 32 is inserted into the mounting frame 31. The inner wall of the mounting frame 31 has protrusions to fix the protective cover 32, thus preventing workers from being accidentally injured by the gear 11 when collecting PVC particles. The worker drags the operating rod 34, causing the insert block 33 to be inserted into the protective cover 32, further fixing the protective cover 32. An auxiliary spring 35 is provided to pull the operating rod 34, thereby limiting the operation rod 34. An inclined surface 36 is provided to help the insert block 33 be inserted into the protective cover 32.
