A cutting and tensioning device for textile fabric production

Abstract

The invention provides a cutting and tensioning device for textile fabric production. A bottom block is fixedly installed on the upper surface of the clip joint, compression springs are fixedly connected to the left and right sides of the bottom block, and the bottom block is slidably installed in the processing chamber. A corresponding ejector rod is arranged above the bottom block, a magnet is arranged inside the top end of the ejector rod, and a corresponding coil is arranged above the magnet and inside the processing chamber. Before the cutting knife is cut, the gear rack and the half gear are meshed and then moved in the movable plate to adjust the resistance value of the variable resistor connected to the circuit, so as to ensure that the magnetic field generated by the coil pushes the magnet and drives the ejector rod to move downward. The rod will drive the mobile frame closer to the inside until it is inserted into the corresponding groove on the top of the bottom block. When the mobile frame presses the bottom block down to ensure that the card joint is vertically downward, it is inserted into the concave hole inside the sticking roller, and the two ends of the textile fabric are aligned. Clamping, the entire structure ensures that the textile fabric is cut when it is in a tensioned state.

Description

technical field [0001] The invention belongs to the technical field of textile processing, in particular to a cutting and tensioning device for textile cloth production. Background technique [0002] Textile fabrics are often made of low-elastic polyester yarns or special-shaped polyester yarns, nylon yarns, cotton yarns, wool yarns, etc., and are woven on various weft knitting machines. During the production of textile fabrics, they need to be rolled into rolls and then cut. In the process of making fashion, fabrics need to be cut into specifications of different lengths. [0003] In the process of cutting textile fabrics, it cannot be cut quickly and efficiently, and the cutting efficiency is low. In addition, when cutting textile fabrics, the fabric is prone to shaking, and the textile fabrics cannot be kept tensioned, resulting in uneven cutting end surfaces and easy damage. Therefore, in view of this, the existing structure and defects are studied and improved, and a c...
