Description
Technical Field
The invention relates to the technical field of textile machinery, in particular to an automatic yarn pressing roller retracting device suitable for a sizing machine.
Background
The beam pressing is an important role of the sizing machine in the beam winding process, and whether the beam pressing is proper or not affects the flatness of the yarn, the tightness of beam winding, the efficiency of a loom and the quality of finished cloth.
In the process of yarn winding of the sizing machine, the pressure of the loom beam is realized by a pair of yarn pressing rollers, the outer circular surface of each yarn pressing roller presses the yarn, and one end surface of each yarn pressing roller is tightly attached to a disc of the loom beam. After the upper hollow shaft is wound with yarn (as shown in figure 6), a pair of yarn pressing rollers are pressed on the loom shaft and axially move towards opposite directions, so that one end surface of each yarn pressing roller is tightly attached to the disc of the loom shaft. Along with the more and more yarn that winds on the beam, the diameter of winding yarn is bigger and bigger (as figure 4), swing arm, bracket, yarn-pressing roller swing back simultaneously, and the bracket rotates the fine setting on the swing arm and guarantees that every yarn-pressing roller all the time presses on the yarn surface until the beam is full (as figure 5). The cylinder drives the swing arm to swing back, so that the pair of yarn pressing rollers are separated from the surface of the loom beam (as shown in figure 7), and the loom beam can fall down smoothly.
Before replacing a new empty beam, in order to ensure that the yarn pressing roller is smoothly lifted and pressed on the beam, a worker needs to bend the waist, drill the waist below the head of the sizing machine, and retract the yarn pressing roller inwards by hands, so that the collision between the yarn pressing roller and a beam disk in the lifting process is avoided.

The working principle of the scheme is as follows: the motor drives the lead screw to rotate through the coupler, so that the movable support can do reciprocating linear motion along the guide rod, the thruster can push the yarn pressing roller, and the retraction of the yarn pressing roller of the sizing machine is realized. The device is initially positioned by detecting the position sensor and adjusting the position of the headstock moving box body.
The automatic retraction device of the yarn pressing roller comprises a double-acting air cylinder arranged on the inner side vertical surface of a moving box body of a machine head, a thruster arranged at the end part of a piston rod of the air cylinder and a position sensor arranged at the front end of a cylinder body of the air cylinder. The working principle of the scheme is as follows: the reciprocating linear motion of the piston rod of the double-acting cylinder drives the thruster to realize the automatic retraction of the yarn pressing roller of the sizing machine.
The invention has the following beneficial effects:
the device of the invention works after the beam falls down and before the empty beam is replaced, so that the yarn pressing roller automatically retracts, and then the device automatically restores to the position before the work. The automatic retraction device of the invention replaces manual operation, reduces the labor intensity of workers and improves the automation control level.
