[0002] Plastic masterbatch is a concentrate made by loading a resin with an excessive amount of plastic additives. When manufacturing plastic products, the additives do not need to be added; only the masterbatch containing the excessive amount can be added in a proportional amount. Therefore, plastic masterbatch is a new type of material specifically designed for polymer processing. There are many varieties of plastic masterbatch available. During the production of plastic masterbatches, the pelletized plastic strips may produce oversized, substandard particles due to the cutting process. These substandard particles must be screened out to ensure uniform particle size in the final product.

Two blocks 32 are fixed to the side walls of the screen body 31. The outer surfaces of the two blocks 32 are slidably connected to the slots 33 provided on the inner wall of the device housing 1. The outer surface of the screening box 3 is provided with fixing bolts 34 that are abutted against the screen body 31. Several limiting rods 35 are fixed to the lower end of the screening box 3.

A guide plate 4 is fixed to the right side of the device housing 1, and a support frame 5 is fixed to the lower end of the device housing 1.

[0029] By adopting the above technical solution, before using the high-temperature protective plastic masterbatch development screening box with easy replacement of the screen, the device housing 1 is first placed in a suitable position, and the support frame 5 provided can ensure the overall stability of the device. When in use, the masterbatch to be screened is introduced into the screening box 3. Under the action of the screen body 31, the larger masterbatch can be blocked, thereby achieving the screening effect. The screened masterbatch falls into the screening box 3 and is discharged through the guide plate 4 for collection. Through the limiting hole 36 provided on the mounting frame 2, with the cooperation of the limiting rod 35, the screening box 3 can be removed, and the blocked masterbatch can be poured out for subsequent processing. When it is necessary to screen masterbatch of different diameters, the fixing bolts 34 on the screening box 3 can be unscrewed, thereby releasing the fixation of the screen body 31. With the cooperation of the block 32 and the slot 33, the screen body 31 can be conveniently taken out and replaced, thereby facilitating the screening and use of masterbatch of different diameters.

[0030] Specifically, such as Figure 1 、 Figure 2 and Figure 3 As shown, the auxiliary mechanism includes a stepper motor 6, which is fixed to the left side of the device housing 1 by bolts.

With the cooperation of the fixed bearing 63, the hinged rod 64 can be driven to move horizontally, and then the movable rod 65 is driven to move, so that the movable rod 65 pushes the mounting frame 2 to move horizontally, thereby shaking the screening box 3. By continuously driving the driving disk 61 to rotate, the screening box 3 can be repeatedly moved horizontally, thereby shaking the internal master particles, which can effectively reduce the blockage of the master particles. The linear bearing 66 is set up to ensure the smoothness of the movement of the movable rod 65, and the guide rod 7 is set up to play a guiding role to avoid the displacement of the mounting frame 2 during movement.

[0032] Working principle: The masterbatch to be screened is introduced into the screening box 3. Under the action of the screen body 31, the larger masterbatch can be blocked. The stepper motor 6 drives the driving disk 61 to rotate, thereby driving the connecting rod 62 to move. Under the cooperation of the fixed bearing 63, the hinged rod 64 is driven to move horizontally, and then the movable rod 65 is driven to move, so that the movable rod 65 pushes the mounting frame 2 to move horizontally, thereby shaking the screening box 3. The screening box 3 repeatedly moves horizontally, thereby shaking the masterbatch inside, and the linear bearing 66 is set. , which can ensure the smoothness of the movement of the movable rod 65. The screened masterbatch falls into the screening box 3 and is discharged through the guide plate 4 for collection. Through the limiting hole 36 set on the mounting frame 2, with the cooperation of the limiting rod 35, the screening box 3 can be removed, and the blocked masterbatch can be poured out for subsequent processing. When it is necessary to screen masterbatch of different diameters, the fixing bolts 34 on the screening box 3 can be unscrewed to release the fixation of the screen body 31. With the cooperation of the block 32 and the slot 33, the screen body 31 can be conveniently taken out for replacement.
