An automatic transport system for the recovery and circulation of defective particles and its application

Abstract

The invention discloses an automatic conveying system for the recycling and circulation of defective particles and its application. The system includes a material-feeding collection device, a screw conveying device and a lifting conveying device. The material-feeding collection device makes the plastic particles Slide along the screen to the connected coarse material outlet and fine material outlet, so that the defective products are collected into the hopper of the corresponding screw conveying device below, and the screw conveying device sends the coarse and fine mixed materials of the defective products to the corresponding In the conveyor belt of the above-mentioned lifting conveying device, the defective granular material is finally transported into the hopper of the granulator, and the top side wall of the hopper is provided with a spray head for spraying the antistatic agent. The invention reduces the frictional static generated by the plastic granules during the mixing process, makes the mixing of defective granules faster and more uniform, improves the efficiency of the screw conveying device, and effectively improves the pass rate and product quality of secondary processed products.

Description

technical field [0001] The invention belongs to the field of automatic conveying equipment, and in particular relates to an automatic conveying system for the recycling and circulation of defective plastic particles; in particular, it relates to an automatic conveying system for the recycling and recycling of defective online plastic particles and its application. Background technique [0002] The main production method of plastic granulation is to produce granular raw materials on the extrusion granulation unit. In the process of granulation production, defective particles of different thicknesses will be produced. The existing processing method is to manually discharge materials from different vibrating screens. The defective granules are picked up by hand, and then manually poured into the hopper of the granulator. First of all, the above method not only consumes a lot of man-hours, but also the coarse material and fine material defective products produced by the granulat...

Problems solved by technology

Although the above technical solution solves the problem of automatic conveying of raw materials, it does not solve the problem of automatic recycling and conveying of defective products, and cannot evenly mix coarse and fine materials

[0004] CN111497169A discloses a kind of on-line plastic granulation particle defective recycling automatic conveying system, the system includes: a feeding collection device, a screw conveying device and a lifting conveying device; the feeding collecting device makes the plastic The particles slide down along the screen to the connected coarse material outlet and fine material outlet, so that the defective products are collected into the corresponding hopper of the screw conveying device below. Point signal response, associated with the screw conveyor and the lifting conveyor to start or stop, the screw conveyor sends the defective coarse and fine mixture to the conveyor belt of the corresponding lifting conveyor, and finally the defective particles The material is transported to the hopper of the granulator; this realizes the automatic circulation of the defective product recovery of the online granulation, which reduces the labor cost and improves the production efficiency. Static electricity leads to plastic bonding, affects the mixing effect, and leads to uneven quality of the final product
