Description

Technical Field

[0001] The utility model belongs to the technical field of impurity screening and removal of plastic pallet raw materials, and particularly relates to a device for screening and removing impurities from plastic pallet raw material particles. Background Technique

[0002] A plastic pallet is a logistics unit used in conjunction with logistics equipment such as forklifts and shelves. It can be used to store, load, and transport goods. It is one of the essential logistics equipment in modern logistics warehousing. The main materials of plastic pallets are polypropylene (PP) and polyethylene (PE). For the convenience of processing, the raw materials of plastic pallets are generally processed into granular form. Before using the granular raw materials for processing, the granular raw materials are generally screened by a screening device to remove impurities therein.

[0003] At present, most plastic pallet granular raw materials need to be screened before use. When the raw materials enter the screening device, they may accumulate, affecting the screening effect of the raw materials. At this time, the user needs to hold the raw materials by hand and continuously and evenly pour the granular raw materials into the screening device. It is relatively laborious for the user to hold the raw materials by hand and continuously pour them. Therefore, a device for screening and removing impurities from plastic pallet raw material particles is needed, which can make the granular raw materials enter the screening device evenly through the feeding structure, avoid material accumulation inside the screening device, and ensure the screening effect of the screening device. Content of the Utility Model

[0004] The purpose of the utility model is to provide a device for screening and removing impurities from plastic pallet raw material particles, which has the purpose of making the granular raw materials enter the screening device evenly through the feeding structure, avoiding material accumulation inside the screening device, and ensuring the screening effect of the screening device, so as to solve the above-mentioned background technical problems.

A sliding frame is slidably connected to the inner cavity of the storage hopper. Four symmetric limiting rods are fixedly connected to the front and back of the sliding frame. Two symmetric limiting grooves are respectively opened on the front and back of the fixed frame. The limiting rods are adapted to the limiting grooves. A fixed rod is welded to the front of the fixed frame. A sliding groove is opened on the front of the fixed frame. The fixed rod slides in the inner cavity of the sliding groove. A connecting rod is rotatably connected to the surface of the sliding groove. A fixing plate is welded to the top of the linear screen. A rotating disc is rotatably connected to the back of the fixing plate. The other end of the connecting rod is eccentrically rotatably connected to the back of the rotating disc. A motor is fixedly connected to the front of the fixing plate through bolts. The output shaft of the motor penetrates through the fixing plate and is fixedly connected to the rotating disc. A baffle plate is welded to the left side of the sliding frame. An opening is opened at the bottom of the fixed frame.

[0023] Embodiment 2:
