Offcut and scrap recycling system

Abstract

The invention discloses an offcut and scrap recycling system. The system is used for a plastic woven belt production line, wherein the plastic woven belt production line comprises a feeding system, adischarging cooling groove, a traction device, a cutting comb and a winding assembly, wherein the feeding system, the discharging cooling groove, the traction device, the cutting comb and the windingassembly are arranged in the discharging direction, the winding assembly comprises a winding drum, a winding shaft, a material guide pipe, guide wheels and a traction wheel, the guide wheel is provided with a wire guide groove perpendicular to an axis, the guide wheels are arranged at the two ends of the winding shaft and are arranged on the winding shaft in a sleeve mode, the traction wheel is provided with a wire pulling groove perpendicular to the axis, the traction wheel is arranged above the feeding system, the material guide pipe is arranged on the same plane with the wire pulling grooveand the wire guide groove, and the rotating speed of the wire pulling groove is synchronous with the speed of the traction device. The system has the advantages that the structure is simple, manual carrying is not needed, the labor intensity is reduced, and manual setting is reduced.

Description

technical field [0001] The invention relates to a production equipment for producing plastic braided belts, in particular to a recycling system for side material waste. Background technique [0002] In the prior art, the raw material for the production of plastic woven bags or plastic woven cloth—the plastic woven belt is cut from plastic film, and the plastic film is made of polypropylene series plastic and calcium carbonate powder filler after being melted at a high temperature of 220°C, extruded and stretched. become. During the stretching process, it needs to be pulled by the traction roller before entering the cutting process. However, in the process of stretching and traction, a film with too large a size will easily cause the thickness on both sides of its cross-section to be greater than the thickness of the middle part, resulting in the plastic film obtained by cutting the plastic film. The thickness of the braid is uneven, which affects the product quality. Theref...

Problems solved by technology

During the stretching process, it needs to be pulled by the traction roller before entering the cutting process. However, in the process of stretching and traction, a film with too large a size will easily cause the thickness on both sides of its cross-section to be greater than the thickness of the middle part, resulting in the plastic film obtained by cutting the plastic film. The uneven thickness of the braid affects product quality, so the parts on both sides of the cross-section of the plastic film itself need to be removed and recycled into the raw material trough of the production line
