Yarn dyeing pipe outer surface filter layer coating machine

Abstract

The invention discloses a yarn dyeing pipe outer surface filter layer coating machine. The yarn dyeing pipe outer surface filter layer coating machine comprises a rack, a coating rotating disc, an ultrasonic welding machine, a filter layer placing frame, a filter layer feeding mechanism as well as a driving part and a control part of the filter layer feeding mechanism. The coating rotating disc is installed on the rack through a bearing base and on the front side of the rack. A rotating disc driver connected with the coating rotating disc is on the back portion of the rack. Bearing shafts are installed on the coating rotating disc, perpendicularly connected with the coating rotating disc through bearings and connected in a driving mode. The filter layer feeding mechanism comprises a horizontal bracket fixed to the rack, a feeding clamp installed on the horizontal bracket, and a clipping device installed on the feeding clamp. A welding head of the ultrasonic welding machine is vertically aligned with the highest busbar of the bearing shafts. The yarn dyeing pipe outer surface filter layer coating machine is simple in structure; full-automatic control is achieved; the efficiency is high; and in addition, a filter layer can be orderly, smoothly and reliably coated on a yarn dyeing pipe.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a filter layer coating machine for the outer surface of a dyeing tube, which is used for coating the filter layer on the outer surface of the dyeing tube. Background technique [0002] In the dyeing process of the general textile industry, dyes in a dye solution are dyed onto textile fiber yarns through exhaust dyeing, so that they become the desired color before weaving the fabric. At present, the most common dyeing machine is used for dyeing operations. The dyeing machine has a plurality of dyeing rods, and each dyeing rod is equipped with a plurality of dyeing tubes. A plurality of nozzle holes are formed in a net-like hollow, and the fiber yarn is wound around the dyeing tube to form a fixation. When dyeing, use the high-pressure pump of the dyeing machine to pressurize the dyeing liquid, the pressurized dyeing liquid will be sprayed out from the nozzle hole, an...

Problems solved by technology

However, since the yarn dyeing bobbins need to bear longitudinal pressure and radial twisting force during the dyeing process, and also bear a certain temperature, the existing dyeing bobbins have the following disadvantages after thermal denaturation: 1. .After the longitudinal deformation, it cannot shrink longitudinally, causing the dyeing tube to bulge and affect the dyeing; 2. The radial deformation makes the dyeing tube twisted, similar to a twist, causing the fiber yarn to wind on the dyeing tube; 3. After being heated, the fiber yarn The thread adheres to the outer wall of the dyeing tube
