Stripping and fixing device of stretching machine

Abstract

An edge peeling and positioning device of a spreading machine belongs to the field of clothing machines. The spreading machine comprises a spreading table, a machine frame is arranged on the spreading table and provided with an upper cloth guiding roller, a lower cloth guiding roller, a cloth pressing roller, a large cloth spreading roller and a lower cloth spreading roller. The edge peeling and positioning device comprises a beam and a pair of toothed belt type edge peeling mechanisms and is characterized by further comprising a front cloth expanding roller, a rear cloth expanding roller and a peeled and expanded cloth edge maintaining roller, wherein the front cloth expanding roller is supported on the machine frame and provided with front cloth expanding threads, the rear cloth expanding roller is provided with rear cloth expanding threads, and the peeled and expanded cloth edge maintaining roller is provided with flanges; the beam is fixedly provided with a pair of belt supporting unit seats, which extend into an edge peeling toothed belt cavity and are fixedly provided with belt supporting units, and the belt supporting units are arranged inside the edge peeling toothed belt cavity and are in contact with the inner side of the edge peeling toothed belt. The edge peeling and positioning device of the spreading machine enables the cloth edges of both sides in the length direction of cloth spread on the spreading table to maintain a trim state, prevents both sides the cloth from moving towards the middle, eliminates the deflection of the edge peeling toothed belt and improves the integral contact effects of the edge peeling toothed belt with the cloth edges.

Description

technical field [0001] The invention belongs to the technical field of garment processing machinery, and in particular relates to an edge stripping and edge fixing device of a stretching machine. Background technique [0002] Spreading machine is also called spreading machine, delaying machine, spreading machine or mopping machine. Its function is to lay the fabric layer by layer on the spreading table in a flat manner according to the process requirements. The process requirements mentioned here are the length of the material, the number of layers of the material, the alignment of the upper and lower layers of the fracture at both ends of the fabric, the alignment of the upper and lower sides of the selvedge, and the flatness of the fabric (no tension), etc. As is well known in the industry, in the garment production process, drawing and cutting play a vital role, because only regular cut pieces can obtain finished garments that meet the specifications, and because if the c...

Problems solved by technology

But there are following shortcomings in this patent application scheme: one, because of the characteristics of curling itself, it is easy to restore the stripped selvage, that is, the curled selvage will immediately recover after going out of the stripping device, so only by stripping It is difficult for the edge device to keep the selvage in a flat state after stripping; secondly, because the pair of edge devices responsible for stripping the selvage do not have the function of stretching (stretching) the cloth from the center of the width direction to both sides , so it is difficult to guarantee the uniformity of the edges on both sides of the long side (that is, the selvedge) laid on the paving table, and there will be defects of different specifications after cutting and even lead to scrapping; The edge-stripping toothed belt of the mechanism (the patent is called the belt) has deflection, so the contact effect with the selvedge is relatively poor, which in turn affects the edge-stripping effect
