Spreading machine for hard fabric

Abstract

A spreading machine for hard fabric comprises a working table. A spreading device, a cutter cloth pressing device and a pneumatic clamp device are installed on the working table. The cutter cloth pressing device comprises a cloth sliding plate and a movable plate. The pneumatic clamp device comprises a chuck assembly. A first comb tooth structure is formed on the lateral side of the side, facing the pneumatic clamp device, of the movable plate. The chuck assembly comprises a lower clamping plate and an upper clamping plate. The lower clamping plate is of a second comb tooth structure. In the state that the cutter cloth pressing device moves to be connected with the pneumatic clamp device, comb teeth of the movable plate and comb teeth of the lower clamping plate are inserted in and matched with each other. Comb teeth of the upper clamping plate and comb teeth of the movable plate are completely staggered with each other in the vertical direction. Because the comb tooth structures matched with each other are formed between the movable plate and the lower clamping plate of the spreading machine for hard fabric and the comb teeth of the upper clamping plate and the comb teeth of the movable plate are completely staggered with each other in the vertical direction, after the movable plate and the lower clamping plate are in comb tooth fit, the pneumatic clamp cannot clamp the comb teeth of the movable plate while clamping cloth, and the cutter cloth pressing device can smoothly retreat.

Description

technical field [0001] The invention relates to a fabric spreading machine, in particular to a fabric spreading machine for hard fabrics. Background technique [0002] In the garment production industry, cloth drawing and cutting play a vital role. Only regular cut pieces have the opportunity to sew clothes that meet the specifications. If the cut pieces are irregular, even the best sewing machine and the best sewing It is also difficult for workers to sew high-quality clothes. Rabbing is the first process of garment making, and the quality of rabbing determines the quality of the entire production. The cloth stretching machine is an important cloth spreading and stacking tool, which can save a lot of manpower. It is mainly used for cloth stretching and cutting, so that the whole roll of cloth can be pulled out to an appropriate length, and then cut into a suitable The size of the cloth, and can achieve automatic feeding and automatic edge. When the existing stretching ma...

AI Technical Summary

Problems solved by technology

Since the edge of the existing movable plate is in a straight line, the cloth must protrude outward from the edge of the movable plate and fall into the lower splint in order to make the chuck of the pneumatic clamp device not press the movable plate while clamping the cloth. However, the cloth protruding from the movable plate is not conducive to the smooth operation of the cloth clamping due to the loss of the support of the movable plate

[0004] In addition, the existing pneumatic clamp devices are mainly fixed by moving. Since this kind of clamp is relatively heavy, two people need to lift it up to move to the corresponding fixed position when moving, which is very inconvenient to move. Moreover, this pneumatic clamp After the jig moves to the corresponding fixed position, the height of the chuck part of the jig cannot be adjusted. Therefore, when it cooperates with the cutter and press device of the stretching machine, it is easy to cause the height position of the movable plate to not match the lower splint. The cloth clamping effect is not good, which affects the subsequent cloth cutting operation
