Improved structure of rapier machine

Abstract

The invention discloses an improved structure of a rapier machine, comprising a rapier machine body, wherein the yarn inlet side of the rapier machine body is provided with a yarn tension adjusting device, the yarn tension adjusting device comprises a frame body on which a yarn running roller, an adjusting roller and a middle roller are arranged, yarn is inputted from the upper end of the adjusting roller after sequentially passing around the yarn running roller, the middle roller and the adjusting roller, the outer annular surface of the adjusting roller is provided with a rubber layer, a height adjusting mechanism of the adjusting roller is connected to the frame body, and a tension inducing device corresponding to each strand of yarn is sleeved on the adjusting roller or the middle roller and is connected in series to a control circuit of the rapier machine. The improved structure has a good tension adjustment function on the yarn at the inlet side of the rapier machine, improves the weaving quality of fabrics, is concise and ingenious, has low cost, and can also sensitively and rapidly induce whether the yarn is broken or not, and if the yarn is broken, the rapier machine can stop running immediately, thereby reducing the scrapping proportion of products.

Description

technical field [0001] The present invention relates to rapier machines. Background technique [0002] In the existing rapier machine, the yarn sent from the creel enters through a large-diameter yarn roller located on the inlet side of the creel. This structure plays a certain role in tensioning the yarn, but the yarn is relatively Yarn jumping is prone to occur, which affects the weaving quality of the fabric, and the adjustment effect needs to be improved. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an improved structure of the rapier machine, which has a good tension adjustment effect on the yarn on the inlet side of the rapier machine, improves the weaving quality of the fabric, has a simple and ingenious structure, and is low in cost. Sensitive and fast sensing whether the yarn is broken, if there is a broken thread, it will stop immediately, reducing the proportion of product scrap. [0004] In order...
