Description
Technical Field
[0001] This utility model relates to the field of warp knitting machine technology, and in particular to a novel warp knitting machine head fixing and locking device. Background Technology
[0002] With social development, warp knitting machines play a vital role in the textile industry, and the warp knitting machine head is mainly used to store and guide yarn, which 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 coils required also increases. Each coil carries approximately 150 to 250 kilograms of yarn. In this case, the traditional bolt-locking method presents numerous problems. When the coils are heavy, the bolts may not be able to securely lock them, and the coils are prone to slippage when the warp knitting machine is running at high speed. This leads to inaccurate yarn feeding during the warp yarn feeding process, which in turn affects the knitting quality of the warp knitting machine, resulting in scrap fabric. This not only causes a significant waste of raw materials and increases production costs, but also reduces production efficiency, affects the product qualification rate, and leads to increased equipment maintenance costs, disrupting the smooth operation of the entire production process and causing economic losses to the enterprise. Summary of the Invention
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a novel warp knitting machine head fixing and locking device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel warp knitting machine head fixing and locking device, comprising a warp beam, wherein multiple heads are fixedly installed on the outer wall of the warp beam, and two symmetrically distributed external locking mechanisms are fixedly installed on the outer wall of the warp beam, wherein the multiple heads are located between the two external locking mechanisms, and an internal locking mechanism is installed inside the warp beam;
[0006] The external locking mechanism includes a first rotating sleeve, a conical block, a second rotating sleeve, and a conical surface. The first rotating sleeve has two threads connected to the outer wall of the warp shaft. The conical block is fixedly connected to the outer wall of the first rotating sleeve. The second rotating sleeve is threadedly connected to the outer wall of the first rotating sleeve. The conical surface is opened inside the second rotating sleeve and fits against the outer wall of the conical block. The inner wall of the conical block is threadedly connected to the outer wall of the warp shaft.
[0007] Furthermore, the outer wall of the warp shaft is fitted with two washers, which are located between the disc head and the first rotating sleeve.
[0008] Furthermore, the external locking mechanism also includes a mounting block and bolts. The mounting block has multiple fixed connections to the outer wall of the first rotating sleeve. The bolts are threaded inside the mounting block, and the washers are located between the pan head and the bolts.
[0009] Further: The internal locking mechanism includes a mounting cylinder, a movable shaft, a first ear plate, a second ear plate, a connecting rod, and an outer support block. The mounting cylinder is fixedly connected inside the warp shaft, and the movable shaft is slidably installed inside the mounting cylinder. Four first ear plates are fixedly connected in a ring to the outer wall of the mounting cylinder, and four second ear plates are fixedly connected in a ring to the outer wall of the movable shaft. The movable shaft is located at the front end of the mounting cylinder. Multiple connecting rods are sequentially and movably installed on the tops of the first and second ear plates. Four outer support blocks are movably installed inside the warp shaft. The tops of the connecting rods are movably installed on the bottoms of the outer support blocks, and the outer wall of the outer support block is in contact with the inner wall of the warp head.
[0010] Furthermore, the internal locking mechanism also includes mounting grooves and sliding grooves. There are four mounting grooves inside the warp shaft, and the first ear plate, the second ear plate, the connecting rod, and the outer support block are all located inside the mounting grooves.
[0011] Furthermore, the internal locking mechanism also includes a third rotating sleeve, an annular movable block, and an annular movable groove. The third rotating sleeve is movably installed at the front end of the mounting cylinder. The inner wall of the third rotating sleeve is threadedly connected to the outer wall of the moving shaft. The rear end of the third rotating sleeve is fixedly connected to the annular movable block. The front end of the mounting cylinder has an annular movable groove, and the annular movable block is located inside the annular movable groove.
[0012] Furthermore, both the second and third rotating sleeves have anti-slip textures on their outer walls.
[0013] Furthermore: a shaft head coupling is fixedly installed at the rear end of the shaft, and a pulley is fixedly installed on the shaft head coupling.
[0014] This utility model has the following beneficial effects:
[0015] 1. Compared with existing technologies, this new method, by setting up an installation cylinder, a moving shaft, a first ear plate, a second ear plate, a connecting rod, an outer support block, a third rotating sleeve, an annular movable block, and an annular movable groove, allows for efficient installation. First, multiple warp heads are installed on the outer wall of the warp beam. Then, the third rotating sleeve is rotated. Since its inner wall is threaded to the outer wall of the moving shaft, the moving shaft moves backward inside the installation cylinder. During this backward movement, the second ear plate moves along with the moving shaft, bringing the first and second ear plates closer together. Through the connecting rod, force is transmitted to the outer support block, causing it to lift upward. The outer wall of the outer support block makes tight contact with the inner wall of the warp head, achieving internal locking and firmly fixing the warp head to the warp beam from the inside. This achieves a secure internal locking of the warp heads, preventing internal loosening caused by the weight of the warp heads during warp knitting machine operation. This improves the operational stability of the warp knitting machine and the quality of the knitted products, reduces the scrap rate, increases production efficiency, and saves costs for enterprises.
[0016] 2. Compared with existing technologies, this method, by setting up a first rotating sleeve, a conical block, a second rotating sleeve, a mounting block, and bolts, and after the internal locking mechanism is installed, washers are installed at both ends of multiple disc heads. Then, two first rotating sleeves are threaded onto the outer wall of the warp shaft, followed by the threaded installation of the second rotating sleeve onto the outer wall of the first rotating sleeve. Due to the contact fit between the conical block and the conical surface, the conical block of the first rotating sleeve is firmly fixed to both ends of the warp shaft. Finally, bolts are installed inside the mounting block. By tightening the bolts, the washers are pushed towards the disc heads, and the two washers compress the multiple disc heads from both ends, achieving external locking of the disc heads. This achieves effective external locking of the disc heads. Under high-speed operation, the double conical surface fit and the compression action of the bolts pushing the washers prevent the disc heads from slipping on the warp shaft, further enhancing the fixing effect of the disc heads.

[0025] Reference Figure 1-6 This utility model provides a novel warp knitting machine head fixing and locking device: It includes a warp beam 1, with multiple heads 2 fixedly installed on the outer wall of the warp beam 1. These heads 2 are important components for storing and conveying yarn. Two symmetrically distributed external locking mechanisms 3 are fixedly installed on the outer wall of the warp beam 1, used to lock the heads 2 from the outside. The multiple heads 2 are located between the two external locking mechanisms 3. An internal locking mechanism 5 is installed inside the warp beam 1, used to lock the heads 2 from the inside. The external locking mechanism 3 includes a first rotating sleeve 301, a conical block 302, a second rotating sleeve 303, and a conical surface 304. The first rotating sleeve 301 has two threads connected to the outer wall of the warp beam 1. The threaded connection between the first rotating sleeve 301 and the warp shaft 1 has a self-locking capability, which can ensure its stable installation. The tapered block 302 is fixedly connected to the outer wall of the first rotating sleeve 301. The shape and size of the tapered block 302 match the tapered surface 304 of the second rotating sleeve 303. The second rotating sleeve 303 is threadedly connected to the outer wall of the first rotating sleeve 301. The tapered surface 304 is opened inside the second rotating sleeve 303. The tapered surface 304 fits against the outer wall of the tapered block 302. This fit between the tapered surface 304 and the tapered block 302 can firmly fix the tapered block 302 of the first rotating sleeve 301 to both ends of the warp shaft 1. The inner wall of the tapered block 302 is threadedly connected to the outer wall of the warp shaft 1, ensuring the tightness of the connection.
[0026] Two washers 4 are fitted on the outer wall of the warp beam 1. The washers 4 are located between the disc head 2 and the first rotating sleeve 301. The washers 4 serve a locking function while also providing cushioning and sealing to prevent wear between components and to prevent damage to the yarn.
[0027] The external locking mechanism 3 also includes a mounting block 305 and a bolt 306. The mounting block 305 has multiple fixed connections to the outer wall of the first rotating sleeve 301. The mounting block 305 provides a mounting base for the bolt 306. The bolt 306 is threaded inside the mounting block 305. The tightening degree of the bolt 306 can be adjusted according to actual needs. The washer 4 is located between the pan head 2 and the bolt 306. Tightening the bolt 306 can push the washer 4 to apply pressure to the pan head 2.
[0028] The internal locking mechanism 5 includes a mounting cylinder 501, a movable shaft 502, a first ear plate 504, a second ear plate 505, a connecting rod 506, and an outer support block 507. The mounting cylinder 501 is fixedly connected to the inside of the shaft 1. The movable shaft 502 is slidably mounted inside the mounting cylinder 501. Four first ear plates 504 are fixedly connected in a ring to the outer wall of the mounting cylinder 501, providing mounting and support for the connecting rod 506. Four second ear plates 505 are fixedly connected in a ring to the outer wall of the movable shaft 502, and the second ear plates 505 and the first ear plates 504 are mutually fitted. The movable shaft 502 is located at the front end of the mounting cylinder 501. Multiple connecting rods 506 are sequentially and movably installed on the top of the first ear plate 504 and the second ear plate 505. The connecting rods 506 can rotate flexibly, which facilitates the transmission of force and the linkage of components. Four outer support blocks 507 are movably installed inside the warp shaft 1. The outer support blocks 507 can move stably inside the warp shaft 1. The top of each connecting rod 506 is movably installed on the bottom of the outer support block 507. The outer wall of the outer support block 507 fits against the inner wall of the pan head 2. The inner wall of the pan head 2 is locked by the support of the outer support block 507.
[0029] The internal locking mechanism 5 also includes mounting grooves 503 and sliding grooves 508. There are four mounting grooves 503 inside the warp shaft 1. The mounting grooves 503 provide installation and movement space for the components of the internal locking mechanism 5. The first ear plate 504, the second ear plate 505, the connecting rod 506 and the outer support block 507 are all located inside the mounting grooves 503, ensuring that the components move in an orderly manner within the specified space and avoiding mutual interference. The sliding groove 508 also provides a guiding function for the movement of the outer support block 507.
[0030] The internal locking mechanism 5 also includes a third rotating sleeve 509, an annular movable block 510, and an annular movable groove 511. The third rotating sleeve 509 is movably installed at the front end of the mounting cylinder 501 and can rotate flexibly at the front end of the mounting cylinder 501. The inner wall of the third rotating sleeve 509 is threadedly connected to the outer wall of the moving shaft 502, and the movement of the moving shaft 502 is realized by the threaded transmission. The rear end of the third rotating sleeve 509 is fixedly connected to the annular movable block 510, which provides limit and guidance for the rotation of the third rotating sleeve 509. The front end of the mounting cylinder 501 is provided with an annular movable groove 511, and the annular movable block 510 is located inside the annular movable groove 511 to ensure the stable rotation of the third rotating sleeve 509.
[0031] The outer walls of both the second rotating sleeve 303 and the third rotating sleeve 509 are provided with anti-slip textures. The anti-slip textures can increase friction and prevent slippage during operation.
[0032] A shaft head coupling 6 is fixedly installed at the rear end of the warp shaft 1. The shaft head coupling 6 is used to connect the warp shaft 1 and the pulley 7 to ensure the transmission of power. The pulley 7 is fixedly installed on the shaft head coupling 6. The pulley 7 can receive external power and drive the warp shaft 1 to rotate.
[0033] Working principle: During operation, multiple disc heads 2 are first installed on the outer wall of the warp shaft 1. Then, the third rotating sleeve 509 is rotated. Since its inner wall is threadedly connected to the outer wall of the moving shaft 502, the moving shaft 502 will move backward inside the mounting cylinder 501. During the backward movement of the moving shaft 502, the second ear plate 505 will move together with the moving shaft 502, so that the first ear plate 504 and the second ear plate 505 will approach each other. Through the connecting rod 506, the force is transmitted to the outer support block 507, causing the outer support block 507 to be pushed upward. The outer wall of the outer support block 507 is in close contact with the inner wall of the disc head 2, thereby locking the disc head 2 internally and fixing the disc head 2 firmly on the warp shaft 1 from the inside.
[0034] Next, washers 4 are installed at both ends of the multiple disc heads 2. Then, two first rotating sleeves 301 are threaded onto the outer wall of the warp shaft 1. Subsequently, second rotating sleeves 303 are threaded onto the outer wall of the first rotating sleeves 301. Due to the contact fit between the conical block 302 and the conical surface 304, the conical block 302 of the first rotating sleeve 301 is firmly fixed to both 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 towards the disc heads 2. The two washers 4 are used to press the multiple disc heads 2 from both ends, thereby locking the disc heads 2 from the outside.
