The driving half gear 601 is installed in the mounting bracket 6 at the bottom end of the rack mechanism 1, and is in engagement with the toothed row assembly 5014 at the bottom end of the front moving assembly 5011. The driving half gear 601 rotates to push the toothed row assembly 5014 to move, thereby driving the moving assembly 5011 to slide in the transverse slot of the guide rail mechanism 5. The spring rod 5012 of the built-in spring structure fixedly arranged inside the guide rail mechanism 5 is connected with the moving assembly 5011, and provides a reset force when the moving assembly 5011 moves, so as to ensure stable movement of the moving assembly 5011. The side plate assembly 501 at the top end of the moving assembly 5011 drives the scraper assembly 5013 inside to move synchronously. The scraper assembly 5013 moves above the conveying belt 1012 to scrape the plastic particles on the conveying belt 1012, so that the plastic particles are evenly distributed on the conveying belt 1012, facilitating subsequent process for the quantitative processing of the particles.

[0064] The support mechanism 3 fixedly arranged in a front-rear symmetry outside the rack mechanism 1 is fixedly connected with the flow converging assembly 301 inside. The air extraction pipe 3011 at the top end of the flow converging assembly 301 is connected with an external vacuum pump. After the vacuum pump is started, the flow converging assembly 301 is air-extracted, so that a negative pressure is formed inside the flow converging assembly 301. The dust generated during the conveying of the plastic particles is sucked into the flow converging assembly 301 and then discharged through the air extraction pipe 3011, so as to collect the dust in the processing environment and improve the working environment.
