Description

Technical Field

[0001] This utility model relates to the field of plastic pellet impurity removal technology, specifically to an impurity removal device for plastic pellet production. Background Technology

[0002] Plastic granules are granular industrial raw materials made from high molecular polymers (mainly synthetic resins) as basic raw materials, with the addition of appropriate additives, through processes such as polymerization and granulation. They are the basic materials for the production of plastic products.

[0003] According to patent document CN112171958A, a vibrating screening machine for plastic granules is disclosed. Its structure includes a discharge port, a screen grid, a stacking box, a spring rod, and a support frame. The discharge port is welded to and interconnected with the screen grid. The stacking box is fixed to the upper surface of the screen grid and interconnected with it. The equipment controls the spring rod to vibrate the screen grid, allowing the material to pass through for screening. Uncut filaments are hung on the pressure body, and subsequent material is pressed upwards, creating a certain resistance force on the outer layer. This allows the plastic granules, when uncut and suspended on the screen grid, to expand and break through the downward pressure. The support body is continuously subjected to force, and the clamping blocks provide appropriate space for buffering, ensuring the connection points have sufficient buffer space and force to prevent excessive stress. Under pressure, the machine can swing as a whole, allowing it to easily bear force and move accordingly.

[0004] In the production of plastic granules, impurity removal is a key step in ensuring product quality. Most existing plastic granule impurity removal equipment uses screen filtration to remove larger plastic impurities by utilizing the difference in material particle size. However, this method can only handle blocky foreign objects that are significantly larger than the plastic granules, and it is powerless to deal with fine impurities such as dust and debris attached to the surface of the plastic granules. Therefore, we propose an impurity removal device for plastic granule production. Utility Model Content

By setting up the cleaning structure 2, during operation, the first motor 201 is started by the controller 4. The first motor 201 drives the drive roller 202 to rotate. With the cooperation of the driven roller 204, the mesh belt 203 can be driven to rotate. Then, the material is poured into the feed chute, so that the material falls onto the mesh belt 203. The top of the conveyor belt 203 allows the material to move along with the conveyor belt 203. Simultaneously, the motor 206 is started, driving the turning roller 207 to rotate, thus turning the material. The water pump 210 is started, drawing water from the water tank 208 and spraying it onto the material surface through the nozzle 211, rinsing the surface and separating dust from the material. A rotating shaft is fixedly connected to the inner cavity of the driven roller 204, and both the front and back of the rotating shaft are movably connected to the housing 1 via bearings. By setting the rotating shaft and bearings, the operation of the driven roller 204 is stabilized. 4. Limiting is implemented to ensure the stability of the driven roller 204 during operation; a limit frame 205 is provided on the top of the mesh belt 203, and a fixing rod is fixedly connected to both the front and back of the limit frame 205, and the top of the fixing rod is fixedly connected to the housing 1.
