Description

Technical Field

[0001] This utility model relates to the field of knitting machine equipment technology, and more specifically to a wear-resistant textile needle cylinder. Background Technology

[0002] Circular knitting machines (or braiding machines) all have a circular needle cylinder. A sinker plate is provided on the upper surface of the needle cylinder and is slidably connected to it. As the sinker plate moves left and right, it moves the yarn, generating pressure and friction against the needle cylinder, easily creating a wear surface on the upper surface. Existing wear-resistant structures typically involve adding wear-resistant steel wire to easily worn areas. However, existing wear-resistant steel wires are usually welded on, and after a period of use, they also wear out. At this point, replacement is either impossible or very troublesome, forcing many companies to replace the entire needle cylinder. This increases production costs and is time-consuming and labor-intensive, increasing the workload for workers. Furthermore, after prolonged operation, lint and rust accumulate on the inner wall of the needle cylinder, affecting its lifespan. Therefore, this invention proposes a wear-resistant textile needle cylinder. This cylinder features detachable wear-resistant protrusions on its upper surface, which are durable and easy to replace. Additionally, the inner side of the needle cylinder is equipped with a lint-removing blade and a lubricating brush to prevent rust and effectively extend the needle cylinder's lifespan.

[0003] To improve the wear resistance of syringes, prevent surface corrosion, and extend service life, Chinese Patent (Authorization Announcement No.: CN219045010U) discloses a wear-resistant double-sided circular knitting machine syringe. This utility model includes a syringe body and a base. A groove is formed at the top of the base, and a rotating mechanism is installed within the groove. A support plate is connected to the rotating mechanism, and multiple positioning rods are mounted on the top of the support plate. Multiple positioning grooves are formed at the bottom of the syringe body, and the positioning rods are movably connected to the positioning grooves. Both the outer and inner layers of the syringe body are provided with wear-resistant layers. The rotating mechanism includes a rotating shaft and a servo motor. The rotating shaft is rotatably installed within the groove and connected to the bottom of the support plate. The servo motor is drive-connected to the rotating shaft, and a drive gear is mounted on the output shaft of the servo motor. A driven gear is sleeved on the outer side of the rotating shaft. This design facilitates the installation and disassembly of the syringe body and allows for convenient rotation of the syringe body, meeting the requirements for rotating operation of the syringe body.

[0004] There are still some deficiencies in the application of this solution. Since sinkers are usually provided on the upper surface of the syringe barrel and are slidably connected to the syringe barrel, the sinkers will drive the yarn to move during the left and right movement, thereby generating pressure and rubbing against the syringe barrel, which is also likely to produce a worn surface on the upper surface of the syringe barrel, resulting in the need to replace the syringe barrel due to wear. At the same time, after the syringe barrel is used for a long time, fluff is likely to adhere to its inner wall and rust appears, which will also affect the service life of the syringe barrel and increase the replacement frequency of the syringe barrel. Therefore, it is necessary to improve the structure of the syringe barrel so that it can avoid wear to the greatest extent, and at the same time has the functions of cleaning and rust prevention, effectively extending the service life and reducing the production cost of enterprises. Summary of the Invention

[0005] The present invention discloses a wear-resistant textile syringe barrel, and its main purpose is to overcome the above-mentioned deficiencies and disadvantages existing in the prior art.

[0006] The technical solution adopted by the present invention is as follows:

[0007] A wear-resistant textile syringe barrel includes a syringe barrel body and wear-resistant ridges. A circular groove is provided at the top of the syringe barrel body. Clamping blocks are provided on the four sides of the circular groove. There are two clamping blocks arranged symmetrically. A spring is provided behind the clamping blocks. The wear-resistant ridges are in an "I" - shaped structure. The lower part of the "I" - shaped structure is adaptively embedded in the circular groove and the middle part is clamped by the clamping blocks. A rotating rod is provided in the middle of the inner side of the syringe barrel body. A cross bar is installed at the top of the rotating rod. Plastic blades and rotating cylinders are respectively installed at the two ends of the cross bar. A sponge ring is wrapped around the outside of the rotating cylinder.

[0008] Furthermore, the circular groove is in a "convex" - shaped structure, and the clamping blocks are arranged on the upper part of the "convex" - shaped structure.

[0009] Furthermore, a hand - push handle is provided at the top of the clamping block, and the clamping block can be掰开 to both sides through the hand - push handle.

[0010] Furthermore, a wear - resistant ceramic sheet is laminated on the top of the wear - resistant ridge, and the wear - resistant ceramic sheet is in sliding contact with the external sinker.

[0011] Furthermore, a rotating motor is installed at the bottom of the rotating rod.

[0012] Furthermore, both the plastic blade and the rotating cylinder are in contact with the inner side wall of the syringe barrel body. An oil injection port is provided at the top of the rotating cylinder and several oil outlet ports are provided on the outer side wall.

The wear-resistant rib is fixed to the top of the syringe body through the clamping block, and a wear-resistant ceramic sheet is fitted on the top of the wear-resistant rib. The wear-resistant ceramic sheet abuts and rubs against the external sinker sheet to replace the direct friction between the upper surface of the existing syringe body and the sinker sheet, which can effectively avoid the wear of the syringe body and improve the service life of the syringe body. Then, when the wear-resistant ceramic sheet on the top of the wear-resistant rib is worn, the clamping block can be掰开 by the hand push handle to replace the wear-resistant rib. The operation is simple and the replacement is convenient, and it can be completed without professional equipment.

[0018] The following further describes the specific embodiments of the utility model by referring to the accompanying drawings.

[0019] As Figures 1 to 3 shown, a wear-resistant textile syringe includes a syringe body 1 and a wear-resistant rib 2. A circular groove 3 is provided at the top of the syringe body 1. Clamping blocks 4 are respectively arranged on the four sides of the circular groove 3. The two clamping blocks 4 are symmetrically arranged. A spring 5 is arranged behind the clamping block 4. The wear-resistant rib 2 has an "I" - shaped structure. The lower part of the "I" - shaped structure is adaptively embedded in the circular groove 3 and the middle part is clamped by the clamping block 4. A rotating rod 6 is arranged in the middle inside the syringe body 1. A cross bar 7 is installed at the top of the rotating rod 6. Plastic blades 8 and rotating cylinders 9 are respectively installed at the two ends of the cross bar 7. A sponge ring 10 is wrapped outside the rotating cylinder 9.

[0020] Furthermore, the circular groove 3 has a "convex" - shaped structure 31, and the clamping block 4 is arranged on the upper part of the "convex" - shaped structure 31.

[0021] Furthermore, a hand push handle 41 is arranged on the top of the clamping block 4, and the clamping block 4 can be掰开 to both sides through the hand push handle 41.

[0022] It should be noted that the word "掰开" in the original text seems to be a wrong or incomplete expression. It might be "opened" in the correct context. The above translation is based on the best understanding of the original text.Furthermore, a layer of wear-resistant ceramic sheet 21 is attached to the top of the wear-resistant ridge 2, and the wear-resistant ceramic sheet 21 slides against the outer settling sheet.

[0023] Furthermore, a rotating motor 61 is installed at the bottom of the rotating rod 6.

[0024] Furthermore, both the plastic blade 8 and the rotating cylinder 9 abut against the inner wall of the syringe body 1, and the rotating cylinder 9 has an oil inlet 11 at the top and several oil outlets on its outer wall.

[0025] [Example]

[0026] First, pry open the clamping blocks 4 on all four sides of the syringe body 1 using the push handle 41, place the wear-resistant protrusion 2 into the circular groove 3, and release the clamping blocks 4. The clamping blocks 4 are then fixed in place by the spring 5 clamping the middle of the wear-resistant protrusion 2. The top of the wear-resistant protrusion 2 is attached to a wear-resistant ceramic sheet 21. When the knitting machine is running, the wear-resistant ceramic sheet 21 of the wear-resistant protrusion 2 abuts against the sinker plate, replacing the existing method of the upper surface of the syringe body 1 directly rubbing against the sinker plate, thus avoiding wear on the upper surface of the syringe body 1. Then, after a period of use, the wear-resistant ceramic sheet on the top of the wear-resistant protrusion 2... After wear, the clamping blocks 4 on the four sides of the circular groove 3 can be pried open by pushing the handle 41, and the wear-resistant protrusion 2 can be taken out and replaced. Finally, after the syringe body 1 has been used for a period of time, lint and rust may appear on its inner wall. At this time, start the rotating motor 61, and drive the crossbar 7 to rotate through the rotating rod 6. The plastic blade 8 on one side of the crossbar 7 scrapes off the lint on the inner wall of the syringe body 1. The sponge ring 10 on the outer side of the rotating cylinder 9 on the other side is filled with lubricating oil, which can be used to brush the inner wall to keep it shiny, prevent rust, and extend its service life.

[0027] As can be seen from the above description of this utility model, compared with the prior art, the advantages of this utility model are as follows:

[0028] This invention firstly features a circular groove at the top of the syringe body, within which a clamping block is installed. The clamping block secures a wear-resistant protrusion to the top of the syringe body. A wear-resistant ceramic sheet is attached to the top of the protrusion, allowing friction between the ceramic sheet and an external settling plate, instead of the direct friction between the syringe body's surface and the settling plate. This effectively prevents wear on the syringe body and extends its service life. Secondly, when the wear-resistant ceramic sheet on the top of the protrusion wears out, the clamping block can be pried open using a push handle to replace the protrusion. The operation is simple and convenient, requiring no specialized equipment. Finally, the inner side of the syringe body includes a rotating motor, a rotating rod, and a crossbar. The crossbar has a plastic blade and a rotating cylinder at each end. The plastic blade scrapes away lint adhering to the inner wall of the syringe body, while the rotating cylinder applies oil to the inner wall, keeping it shiny and rust-free, further extending the syringe body's service life. This invention has a novel structure, ingenious design, and strong practicality, making it suitable for widespread application.

[0029] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial improvements made to this utility model using this concept should be considered as infringing on the protection scope of this utility model.
