Most existing masterbatch pelletizers are integrated, which is inconvenient to disassemble and clean, thus affecting the neatness of the device, and after pelletizing, the masterbatch is mixed with powder and is difficult to remove.

[0003] The existing masterbatch pelletizer is equipped with a drainage plate, a screen plate, a collecting box, a partition and a vibration motor, and generally adopts blade cutting or crushing roller rolling. However, blade cutting will cause the raw materials to collide in the chassis, resulting in loud noise, and the crushing roller generally has only one-stage crushing, directly crushing the raw materials to the discharge, which will cause jamming and poor crushing effect during the crushing process.

[0004] Therefore, we propose a plastic strip pelletizer with the function of removing powder and debris to solve the above problems. Utility Model Content

[0020] The embodiment of the utility model provides a plastic material strip pelletizer with a powder removal function, which solves the existing masterbatch pelletizer in the prior art. The pelletizer is provided with a drainage plate, a screen plate, a collection box, a partition and a vibration motor, and generally adopts blade cutting or crushing roller rolling. However, the blade cutting will cause the raw materials to collide in the machine box, making a lot of noise, and the crushing roller generally has only one-stage crushing, which directly crushes the raw materials to the discharge, causing jamming and poor crushing effect during the crushing process. By setting the feed hopper and the crushing mechanism on the outer shell, it is realized that when the staff uses the device to crush the materials , put the material to be processed into the material inlet, start the motor, and when the motor rotates, it drives the crushing roller to rotate, and the crushing roller crushes the material. The crushed material falls on the first screening plate, and the larger material slides out through the first screening plate, and the smaller material falls on the second screening plate. When the gear rotates, the bevel gear 1 connected to the gear rotates, and the bevel gear 1 drives the bevel gear 2 to rotate, so that the turntable coaxially rotating with the bevel gear 2 rotates, and the eccentric cylinder arranged on the turntable drives the connecting rod to reciprocate and drives the second screening plate to reciprocate up and down, so as to realize the shaking and discharging of the material scattered on the second screening plate.

[0021] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] Reference Figure 1-2 A plastic material strip pelletizer with a powder removal function comprises a device housing 1, and a material inlet 2 for adding materials is provided on the top of the housing 1.

[0023] Reference Figure 1-3A lower hopper 8 is fixedly provided at the port of the feed inlet 2. The lower hopper 8 is funnel-shaped with a large top and a small bottom. By setting the lower hopper 8 on the port of the feed inlet 2, the staff can place the material on the lower hopper 8 when adding materials, and the material can move along the inner wall of the lower hopper 8 to the inside of the device.

[0024] The feed inlet 2 is provided with a crushing mechanism for crushing plastic material strips.

[0025] Reference Figure 2-4 The crushing mechanism includes a motor 9 fixedly arranged on a housing 1, and two crushing rollers 10 are rotatably arranged on the housing 1. Gears 11 are fixedly arranged on the shafts of the two crushing rollers 10, and the two gears 11 are meshed with each other. The output end of the motor 9 is fixedly connected to one of the crushing rollers 10, and the motor 9 is provided with a transmission unit for controlling the shaking of the second screening plate 5. Through the motor 9 arranged on the housing 1, when the staff starts the motor 9, one of the crushing rollers 10 is fixedly connected to the output end of the motor 9, and the other crushing roller 10 is driven by the gear 11, so that the two crushing rollers 10 rotate towards each other to crush the plastic material.

[0026] Reference Figure 2-4 The transmission unit includes a bevel gear 12 fixedly arranged at the axis center of one of the gears 11, a bevel gear 2 13 meshing with the bevel gear 12 is rotatably arranged on the housing 1, a turntable 14 is fixedly arranged on the other end of the bevel gear 2 13, a rotating shaft is eccentrically arranged on the turntable 14, a cylinder is fixedly arranged on the second screening plate 5, and the cylinder and the rotating shaft are connected by a connecting rod 15 for transmission. Through the bevel gear 12 arranged at the axial position of the gear 11, when the gear 11 rotates, the bevel gear 12 fixedly connected with the coaxial jaws between the gears 11 rotates, the bevel gear 2 13 meshing with the bevel gear 12 rotates, and the turntable 14 fixedly arranged on the bevel gear 2 13 rotates, and the eccentrically arranged cylinder on the turntable 14 can drive the second screening plate 5 to reciprocate up and down through the connecting rod 15. When the second screening plate 5 shakes, the material on the second screening plate 5 is swung to ensure that the crushed material can slide to the next place of the device.

[0027] A first screening plate 3 is fixedly arranged inside the outer shell 1, and the end of the first screening plate 3 close to the feed port 2 is higher and the vertical position of the end far from the feed port 2 is lower.
