Description
Technical Field
[0001] The utility model belongs to the technical field of particle granulators, in particular to a plastic particle granulator. Background Art
[0002] The plastic pellet granulator can process waste plastic or plastic raw materials into high-quality, uniform-sized particles for further production and use. After the pellet granulator extrude the plastic raw materials, a screening device is required to separate the qualified particles from the unqualified particles. Most traditional screening devices directly knock the bottom of the screen plate by rotating the cam, so that the screen plate moves up and down to screen the plastic particles on the screen plate. After the screen plate is knocked by the cam for a long time, the contact surface between the cam and the screen plate wears more severely, and the screen plate is easily damaged. The staff needs to replace the screen plate regularly, which increases the cost of maintenance and replacement.
[0003] For example, the utility model with announcement number CN221774974U discloses a plastic particle granulator. In the technical solution of this patent, a screening plate is provided inside the lower end of the granulation box, and a rotating column is rotatably provided at the lower end of the screening plate. A cam is provided in the middle of the rotating column. The cam drives the vibration rod to move up and down, thereby knocking the lower end of the screening plate through the vibration rod, causing the screening plate to swing up and down, thereby screening the particles on the screening plate. After the screening plate is knocked by the vibration rod for a long time, the bottom of the screening plate is easily worn, shortening the service life of the screening plate. The staff needs to regularly inspect and replace the screening plate, which increases the maintenance cost and affects the overall production efficiency of the equipment. Utility Model Content

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a plastic particle granulator includes a box body, a feed port is provided at the upper end of the box body, a feed hopper is provided at the feed port, a granulation mechanism is provided in the middle of the box body, and a screening mechanism is provided at the lower end of the granulation mechanism.

[0007] As a further improvement of the present invention, the granulation mechanism includes a rotating column symmetrically arranged at the upper end of the interior of the box body, and a granulation roller is provided on the rotating column. The positions of the two granulation rollers are adapted to each other. The front end of the box body is provided with a driving member 2 for driving the rotating column to rotate. The driving member 2 includes an installation box arranged at the front end of the box body. The two rotating columns are connected with gears through the side wall of the box body.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0010] First, by setting up a screening mechanism and starting the telescopic push rod, the adjustment plate is driven to slide back and forth along the slide seat, and then the roller is moved back and forth up and down along the adjustment plate. The roller drives the slide rod to move back and forth up and down, so that the screen plate constantly fluctuates up and down, enhancing the vibration effect of the screen plate, thereby separating the particles that meet the requirements from the particles that do not meet the requirements through the sieve holes, thereby improving the screening efficiency.
[0011] Secondly, by setting up the second driving part, the motor drives the gear to rotate, and the gear drives the corresponding rotating cylinder to rotate synchronously.

[0012] Third, several support bases are set at the bottom of the box, and anti-slip stripes are opened on the bottom outer wall of the support base. The anti-slip stripes can significantly increase the friction between the support base and the ground, preventing the equipment from sliding due to vibration or external force during operation, thereby improving the stability of the equipment.
[0013] Fourthly, by setting the guide plate 1, the plastic raw materials can be guided between the granulation rollers, reducing the waste of raw materials and ensuring that each batch of raw materials can be fully utilized. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figure 2 、 3 As shown, the driving member 1 includes a slide 207 fixedly arranged inside the fixed frame 203, and an adjustment plate 208 that conflicts with the roller 206 is slidably provided on the upper end of the slide 207. A telescopic push rod 209 is provided at the left end of the fixed frame 203, and the telescopic end of the telescopic push rod 209 is connected to the rear side wall of the adjustment plate 208. When the telescopic push rod 209 is started, the adjustment plate 208 is driven to slide back and forth along the slide 207, and then the roller 206 is moved up and down reciprocatingly along the adjustment plate 208. The roller 206 drives the slide 202 to move up and down reciprocatingly, so that the screen plate 104 is constantly fluctuating, thereby enhancing the vibration effect of the screen plate 104, thereby separating the particles that meet the requirements from the particles that do not meet the requirements through the sieve holes, and improving the screening efficiency.
