Technical Field

the invention relates to auxiliary facilities in the textile industry, in particular to a driving device of a weaving beam for parallel yarn pulling of a leasing machine.

Background

The function of the leasing machine is to divide the warp yarns with higher density into a plurality of layers through leasing equipment so as to carry out the subsequent drafting process. Before leasing, the warp yarns on the beam are pulled apart and pulled to a leasing machine in parallel, and the process is called yarn pulling. In the prior art, the yarn pulling is realized by withdrawing the yarn of a driving shaft, placing the yarn on the ground and pulling the yarn to a leasing machine in parallel, and the warp yarn of the driving shaft must roll when withdrawing, so that the withdrawn yarn is contacted with the ground to generate stains, and the yarn is difficult to be parallel to the leasing machine after the driving shaft rolls.

disclosure of Invention

The invention aims to solve the technical problem of providing a driving device of a weaving shaft for parallel yarn pulling of a leasing machine, which can prevent the warp yarn from being polluted in the unwinding process and is beneficial to ensuring the parallelism of the yarn and the leasing machine.

In order to solve the technical problem, the driving device of the weaving shaft for parallel yarn pulling of the leasing machine comprises an open box body, wherein the upper parts of the front side plate and the rear side plate of the box body are respectively cut into bearing plates along the horizontal direction, the width of the bearing plates along the horizontal direction is smaller than that of the box body, two groups of bayonets are arranged on the bearing plates, and the driving device also comprises two groups of rolling shaft assemblies arranged on the bayonets, wherein the two groups of rolling shaft assemblies are parallel to the front axis and the rear axis of the box body;

the upper end surface of the box body is provided with a left cover plate and a right cover plate along the front and back axial directions, and an upper opening is formed between the left cover plate and the right cover plate; support columns are arranged between the two cover plates and the bottom plate of the box body;

The roller component comprises a roller, and rollers are movably arranged on the roller through bearings at two ends; the shaft end of the rolling shaft is clamped with the bayonet; the upper surface of the cover plate is not higher than the upper edge of the roller; the rollers are not interfered with the box body and the supporting columns and can freely rotate;

The bottom plate of the box body is provided with a plurality of fixing holes, and the expansion bolts fix the box body on the floor through the fixing holes.

the cover plate is provided with a plurality of upper convex blocks, and a plurality of slots are formed in the bottom plate of the box body in a matched milling control mode. Under the condition that the height is not enough, two box bodies can be combined for use, and 2 box bodies are simultaneously fixed on the floor through the lengthened expansion bolts through the fixing holes, so that the use mode is flexible.

The advantages of the above technology are reflected in: A. the device can control the beam at a fixed position and keep the beam at the shortest distance from the lease machine, and the beam is overhead and separated from the ground during operation, so that warp yarns can not fall to the ground, and the warp yarns can be prevented from being polluted; B. the device is combined for use, the two ends of the beam are synchronously rotated after the beam is erected, namely, the beam only rotates and does not deflect in the operation process, and the parallelism of the warp and the leasing machine is favorably kept.
