An upgraded temple device for a shuttleless loom and its adjustment method

Abstract

The invention provides an upgraded temple device of a shuttleless loom and an adjustment method of the upgraded temple device. The upgraded temple device comprises a mounting plate, a rack and a fabric carrying plate; the rack is provided with a hollow cavity, a spring sliding block mechanism is arranged in the hollow cavity and comprises a sliding block located on the lower portion, the top of the sliding block is connected with a screw in a thread fitting mode, a nut is fixedly arranged on the top of the screw, a spring is arranged under the sliding block, the sliding block is perpendicularly and fixedly connected with a long shaft, the long shaft is rotatably connected with licker-in in a sleeved mode, and the licker-in is fixedly sleeved with a plurality of obliquely-arranged thorn rings; the fabric carrying plate is provided with a pressure sensor, a sensing head of the pressure sensor is upwards arranged, a height adjustment assembly is arranged under the pressure sensor and comprises a fixed barrel and a lifting shaft which are connected in a thread fitting mode, the fixed barrel is fixedly mounted on the fabric carrying plate, the top end of the lifting shaft is fixedly connected with the pressure sensor, a pressing plate is fixed to the long shaft, and the pressing plate and the sensing head of the pressure sensor form pressure contact after the long shaft falls.

Description

technical field [0001] The invention belongs to the technical field of weaving, and relates to a shuttleless loom, in particular to an upgraded temple device of the shuttleless loom and an adjustment method thereof. Background technique [0002] In the process of fabric formation, the warp and weft yarns interweave with each other, and the warp and weft yarns buckle due to the tension in the weaving process. The buckling of the weft yarn reduces the width of the fabric, so that there is a difference between the door width and the reed width at the weaving mouth of the loom, that is, a certain shrinkage occurs. And the warp yarn has a larger inclination, which increases the friction between the side warp yarn and the reed sheet, causing the side warp yarn to break easily. Installing the temple device on both sides of the fabric can stretch the fabric to make it reach the predetermined fabric width, and can also prevent the side warp from tilting. The working principle of th...

AI Technical Summary

Problems solved by technology

However, when weaving yarn-dyed, wider or lighter fabrics, due to the lack of lateral tension provided by the temples, the fabric shrinks to a certain extent when it enters the take-up roller, so that it passes through the take-up roller. Obvious shrunken prints appear after removal, which is difficult to remove for colored fabrics, which greatly affects the appearance quality of the product
