Description

Technical Field

[0001] The invention relates to the technical field of warp knitting machines, and in particular to a novel warp knitting machine disc head fixing and locking device. Background Art

[0002] With the development of society, warp knitting machines play a vital role in the textile industry. The warp knitting machine head is mainly used to store and guide yarns and is an important component to ensure the normal operation of the warp knitting machine.

[0003] However, in existing warp knitting machines, as the width increases, the number of yarn heads required also increases. The mass of yarn carried by each head is about 150 to 250 kilograms. In this case, many problems will arise when using traditional bolt locking methods. When the head is heavy, the bolt may not be able to lock it firmly, and when the warp knitting machine is running at high speed, the head is prone to slipping. This will lead to inaccurate yarn delivery during the warp yarn feeding process, which in turn affects the weaving quality of the warp knitting machine, and the produced fabric becomes waste. This will not only cause a huge waste of raw materials and increase production costs, but also reduce production efficiency, affect the product qualification rate, and lead to an increase in equipment maintenance costs, affecting the smooth progress of the entire production process, and causing economic losses to the company.

The first ear plate has four annular fixed connections to the outer wall of the mounting tube, and the second ear plate has four annular fixed connections to the outer wall of the movable shaft. The movable shaft is located at the front end of the mounting tube. The connecting rod has a plurality of movably installed on the top of the first ear plate and the second ear plate in sequence. The outer support block has four movably installed on the inside of the warp shaft.

[0012] Furthermore: the outer walls of the second rotating sleeve and the third rotating sleeve are both provided with anti-slip grooves.

[0013] Further: a shaft head coupling is fixedly installed at the rear end of the warp beam, and a pulley is fixedly installed on the shaft head coupling.

Since its inner wall is threadedly connected with the outer wall of the moving shaft, the moving shaft will be driven to move backward inside the installation tube. During the backward movement of the moving shaft, the second ear plate will move with the moving shaft, so that the first ear plate and the second ear plate are close to each other. Through the connection of the connecting rod, the force is transmitted to the outer support block, so that the outer support block is pushed upward, and the outer wall of the outer support block is in close contact with the inner wall of the disc head, so as to realize the internal locking of the disc head, and the disc head is firmly fixed on the warp shaft from the inside. The firm locking of the disc head from the inside is realized, and during the operation of the warp knitting machine, the internal loosening problem caused by the heavy weight of the disc head can be avoided, the operation stability of the warp knitting machine and the quality of the woven products are improved, the scrap rate is reduced, the production efficiency is improved, and the cost is saved for the enterprise.

[0016] 2. Compared with the prior art, by setting the first rotating sleeve, the conical block, the second rotating sleeve, the mounting block and the bolt, after the internal locking mechanism is installed, washers are installed at both ends of the multiple disc heads, and then the two first rotating sleeves are threadedly installed on the outer wall of the warp shaft, and then the second rotating sleeve is threadedly installed on the outer wall of the first rotating sleeve. Due to the contact and cooperation between the conical block and the conical surface, the conical block of the first rotating sleeve is firmly fixed on both ends of the warp shaft. Finally, the bolt is installed inside the mounting block, and the washer is pushed to move in the direction of the disc head by tightening the bolt. The two washers are used to squeeze the multiple disc heads from both ends to achieve the locking of the disc heads from the outside. The effective locking of the disc heads from the outside is achieved. Under the condition of high-speed operation, the disc heads can be prevented from slipping on the warp shaft through the cooperation of the double conical surfaces and the squeezing effect of the washers pushed by the bolts, which further enhances the fixing effect of the disc heads.

The second ear plate 505 has four annular outer walls fixedly connected to the movable shaft 502. The second ear plate 505 and the first ear plate 504 cooperate with each other. The movable shaft 502 is located at the front end of the mounting tube 501, and a plurality of connecting rods 506 are movably mounted on the top of the first ear plate 504 and the second ear plate 505 in sequence. The connecting rod 506 can be flexibly rotated to facilitate the transmission of force and the linkage of components.

Subsequently, the second rotating sleeve 303 is threadedly installed on the outer wall of the first rotating sleeve 301. Due to the contact and cooperation between the tapered block 302 and the tapered surface 304, the tapered blocks 302 of the first rotating sleeve 301 are firmly fixed on the two ends of the warp shaft 1. Finally, bolts 306 are installed inside the mounting block 305. By tightening the bolts 306, the washers 4 are pushed to move in the direction of the pan heads 2. The multiple pan heads 2 are squeezed from both ends by using the two washers 4 to achieve locking of the pan heads 2 from the outside.
