Description

Clamping type cloth cutting equipment

Technical Field

The utility model belongs to the technical field of cloth cutting equipment, and particularly relates to clamping type cloth cutting equipment.

Background

When the cloth is cut, the cutting efficiency can be improved by superposing the multi-layer cloth. And when cutting out the cloth, in order to avoid cloth to take place the displacement and lead to cutting out the position inaccurately on the cloth, cut out even to the fretwork position and lead to the fact the cloth piece shape of cutting out to be inconsistent with the requirement, lead to the fact the waste of cloth. Therefore, before the cloth is cut, the cloth needs to be fixed, and after the cloth is fixed, the cloth is cut by a cutting tool. The cloth of the multiple layers can be fixed in a pressing mode, and the cloth is pressed from the upper side by adopting structures such as a pressing plate or a pressing frame, so that the positions of the cloth of each layer are kept unchanged.

However, when the multi-layer cloth is fixed by adopting the structure such as the pressing frame, the pressing frame cannot be used for driving the cloth to move, that is, the cloth cannot move, and at the moment, the cutting tool needs to move relative to the plane of the cloth, so that cutting is performed at different positions of the cloth. After the cutting tool cuts a part of the cloth, the part of the cloth which is not cut needs to be repositioned and fixed, and then the cutting tool can continue cutting work. Therefore, when cutting cloth that needs to be pressed and fixed for multi-layer placement, positioning and pressing operations need to be frequently performed, resulting in low cutting efficiency. And the positioning accuracy of cloth is reduced due to the multiple positioning and pressing operations, and the cutting position offset can be caused by the reduced positioning accuracy, so that the incomplete shape of the cut cloth piece is caused.

Disclosure of utility model

The utility model aims to provide clamping type cloth cutting equipment which is used for solving the problems of low cloth cutting efficiency and low cloth positioning precision.
