Description

Technical Field

[0001] The present invention relates to the technical field of flax yarn winding, in particular to the technical field of a flax yarn winding device. Background Art

[0002] Flax yarn is a kind of yarn made of flax fiber. It is the earliest natural fiber used by humans and the only bundled plant fiber in natural fibers. It is usually processed into products of a certain fineness and used for weaving, rope making, thread making, knitting, embroidery, etc. Because it has excellent moisture absorption, air permeability, anti-corrosion, antibacterial, low static electricity and other characteristics, it is known as the "fiber queen" by people.

[0003] During the processing of yarn, it is usually necessary to wind it up for convenient storage, handling and subsequent use. In the existing yarn winding process, manual winding and packing are carried out, with low efficiency and long working hours. At the same time, due to the high cost of fully automatic equipment, the burden on enterprises is increased.

[0004] To solve the problems raised in the above technology, for example, the yarn winding machine disclosed in Application No. CN201721348704.3 includes a box body. A partition is provided in the box body. A number of through holes are evenly arranged on the partition. A winding shaft is provided in the through holes. The winding shaft is movably arranged in the through holes. A horizontally arranged worm is provided below the partition in the box body. A motor for driving the worm is provided outside the box body. A worm gear is provided at the bottom of the winding shaft. The worm gear meshes with the worm. The yarn passes through the yarn hole on the front wall of the box body, and the yarn is wound around the winding shaft. The motor drives the worm to drive the worm gear, and the worm gear drives the winding shaft to rotate for winding operation, improving work efficiency and reliable operation. When an appropriate amount of yarn is wound around the winding shaft, the winding shaft is taken out to facilitate taking out the yarn, and then the winding shaft is put down to continue winding.

[0005] The above device cannot adjust the tension of the yarn, so it is often easy to cause the phenomenon that the yarn is not wound tightly and orderly during yarn winding, which is not conducive to the efficient winding of the yarn.

[0006] To solve the problems raised in the above technologies, for example, the yarn winding device disclosed in Application No. CN202020979425.2 includes a traction device, a tension adjustment device, a thread passing device, a winding device, and a fixed bottom plate. The traction device, the tension adjustment device, the thread passing device, and the winding device are fixedly installed on the fixed bottom plate from left to right. The traction device includes a first support frame and a traction wheel. The first support frame is fixedly installed on the fixed bottom plate. There are two or more traction wheels arranged in an up-and-down position at the top of the first support frame. The tension adjustment device includes a fixed box and a threaded rod. The fixed box is fixedly installed on the fixed bottom plate. The inside of the fixed box is in a hollow state, which can adjust the tension of the yarn during winding, so as to facilitate the rapid and efficient winding of the yarn. At the same time, it can also effectively prevent the wound yarn from becoming scattered.

[0007] However, the above device still has the following defects: 1. During the production process of linen yarn, there are many fiber particles on its exterior. The fiber particles attached to the surface of the linen yarn will friction and cause wear on the surface of the linen yarn due to the winding problem, resulting in fiber breakage, cutting, or other forms of damage. At the same time, after the fiber particles attach to the dust in the air, it will affect the appearance and cleanliness of the yarn; 2. After the winding is completed, the yarn needs to be cut manually, resulting in a cumbersome operation and time-consuming and laborious problems. Summary of the Invention

The two brackets are respectively installed in parallel on the side walls of the coiling seats. One end of each bracket is connected with a fixed seat. The inside of the fixed seat is of an open structure, and a bidirectional screw is rotatably arranged in the opening. The upper and lower threads of the bidirectional screw have opposite thread directions. The upper and lower outer walls of the bidirectional screw are both threadedly connected with a first moving block. The first moving blocks at the upper end of the bidirectional screw are connected with an upper scraping plate through a support rod, and the first moving blocks at the lower end of the bidirectional screw are connected with a lower scraping plate through a support rod.

[0018] Advantages of the present invention: 1. Through the combined cooperation of the bidirectional screw, the first moving block, the upper scraping plate, the lower scraping plate and the antistatic brush, the present invention can clean the outside of the yarn. After the yarn passes through between the upper scraping plate and the lower scraping plate and is wound on the winding roller, the staff rotates the hand wheel at the same time, thereby driving the bidirectional screw to rotate. After the bidirectional screw rotates, it drives the moving blocks to approach each other, thereby driving the upper scraping plate and the lower scraping plate to approach each other, so that the antistatic brushes on the upper scraping plate and the lower scraping plate are in close contact with the outer surface of the yarn. When the yarn is being wound, the antistatic brush can clean the residual particles on the surface of the yarn, avoiding the friction between the fiber residues and the surface of the yarn during the winding process and causing wear, preventing fiber breakage, cutting or other forms of damage caused by wear, and improving the strength, ductility and durability of the yarn; 2. Through the combined cooperation of the hydraulic cylinder, the piston rod, the cutting tool and the cutting tool seat, the present invention can automatically cut the yarn. After the yarn winding is completed, the hydraulic cylinder is started to drive the piston rod to descend, and the piston rod drives the cutting tool to descend to cut the yarn. At the same time, the cutting tool groove on the cutting tool seat buffers the cutting tool when it falls, avoiding the direct fall of the cutting tool and colliding with the base, and eliminating the need for staff to cut, which saves time and effort.
