Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically to a jacquard fine-tuning device for a large circular knitting machine. Background Technology

[0002] "Circular knitting machine" is a common name for a core production equipment in the knitting industry. Its formal name is usually single-sided circular knitting machine or double-sided circular knitting machine. Sometimes it is also directly called a circular knitting machine. It is used to continuously and efficiently produce tubular knitted fabrics. The knitting disc (also called needle disc or large disc) of the circular knitting machine is one of the core components of the circular knitting machine (circular weft knitting machine). It is responsible for fixing the knitting needles, controlling the movement trajectory of the needles, and cooperating with the loop forming system to complete the knitting of the fabric. When using the circular knitting machine, sometimes in order to obtain a denser or looser jacquard structure, it is necessary to adjust the angle of the knitting disc to obtain different jacquard effects on the fabric.

[0003] Although the existing technologies mentioned above can solve the corresponding technical problems, they still have certain drawbacks: the existing adjustment methods adjust the rotation angle by directly twisting the knitting disc. Although the angle can be controlled to a certain extent, it is difficult to accurately control the rotation range by visual observation during adjustment. The accuracy of the angle adjustment is often poor, and additional tools such as measuring rulers are required to judge the adjustment distance, which is very inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a large circular knitting jacquard fine-tuning device that is easy to observe and adjust with high precision.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a jacquard fine-tuning device for a circular knitting machine, comprising a fixed base and a collar whose outer wall is attached to one side of the fixed base and can slide relative to each other, wherein the collar is fitted and fixed to the bottom outer wall of the knitting disc of the circular knitting machine.

[0006] A further improvement is that the fixing base includes a fixing block and an observation port integrally formed on the fixing block.

[0007] A further improvement is that the side wall of the fixed seat is provided with a stopping device that fits against the outer wall of the collar.

[0008] A further improvement is that the stopping device includes a base disposed on one side of the fixed seat and an integrally formed threaded hole that penetrates the base, wherein a fixing bolt is engaged in the threaded hole.

[0009] A further improvement is that the fixing bolt includes a bolt post that engages with a threaded hole and an elastic pressure block disposed at the top of the bolt post.

[0010] A further improvement is that a hexagonal screw block is provided at the bottom end of the bolt column.

[0011] A further improvement is that the ring includes a ring body and several scale marks integrally formed on the ring body.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are as follows: When using this utility model, the loop can be fitted onto the bottom outer wall of the knitting disc, and the elastic pressure block at the top of the loop can be pressed against the loop by screwing in the fixing bolt. The loop is fixed by friction and will not rotate, thus fixing the loop together with the knitting disc. When it is necessary to adjust the angle of the knitting disc, the fixing bolt is screwed out in the opposite direction and the loop is rotated. At the same time, the scale marks on the loop can be observed through the observation port to accurately control the rotation angle. After adjusting to the appropriate angle, the fixing bolt can be screwed in again for fixation. When adjusting the angle, it can be conveniently observed through the observation port and the scale marks. The angle adjustment is controllable and highly accurate. There is no need to use measuring tools or other tools for adjustment, making it convenient to use. Attached Figure Description

[0018] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0019] See Figure 1-4As shown, the technical solution adopted in this specific embodiment is: a jacquard fine-tuning device for a circular knitting machine, including a fixed base 1 and a collar 4 whose outer wall is attached to one side of the fixed base 1 and can slide against each other. The collar 4 includes a collar body 41 and several scale lines 42 integrally formed on the collar body 41. The collar 4 is fitted and fixed to the bottom outer wall of the knitting disc of the circular knitting machine. The fixed base 1 includes a fixing block 11 and an observation port 12 integrally formed on the fixing block 11. In use, the collar body 41 of the collar 4 is fitted into the knitting disc fixed below the circular knitting machine. The circular knitting machine and the knitting disc of the circular knitting machine are existing technologies and will not be described in detail here. The outer wall of the collar body 41 is attached to one side of the fixing block 11 of the fixed base 1. The fixing block 11 has a groove with the same curvature as the groove on the side that is attached to it, thereby making the collar body 41 fit against the fixing block 11. The loop body 41 can fit fully against one side of the fixing block 11. When it is necessary to adjust the angle of the knitting disc, simply rotate the knitting disc and make the loop body 41 fixed on the knitting disc rotate synchronously. During the rotation of the knitting disc, observation can be made through the observation port 12. Several scale marks 42 formed on the outer wall of the loop body 41 can be easily observed through the observation port 12. During the rotation, the rotation angle can be judged by observing the scale marks 42, thereby accurately controlling the rotation angle. After adjusting to the appropriate angle, stop the rotation and fix the knitting disc. When adjusting the angle, it can be easily observed through the observation port 12 and the scale marks 42. The angle adjustment is controllable and highly accurate. There is no need to use measuring tools or other tools for adjustment, making it convenient to use.

[0020] The side wall of the fixed base 1 is provided with a stopping device that fits against the outer wall of the collar 4. The stopping device includes a base 21 set on one side of the fixed base 1 and a threaded hole integrally formed and penetrating the base 21. A fixing bolt 2 is engaged in the threaded hole. The fixing bolt 2 includes a bolt post 23 that engages with the threaded hole and an elastic pressure block 24 set on the top of the bolt post 23. After the angle adjustment is completed, the fixing bolt 2 can be screwed into the threaded hole, so that the elastic pressure block 24 on its top fits against the collar body 41. The elastic pressure block 24 can be a rubber block structure with a roughened surface. The pressure generated by screwing in the bolt post 23 can form a strong friction force on the outer wall of the collar body 41, thereby quickly locking the collar body 41 and preventing it from shifting or shaking. Thus, after the angle adjustment is completed, the collar body 41 and the knitting disc can be fixed together to prevent them from shaking and affecting the accuracy of the angle adjustment. At the same time, the fixing operation is simple and convenient.

[0021] The bottom end of the bolt post 23 is also provided with a hexagonal screw block 22, which makes it easier to screw the bolt post 23 in through the hexagonal screw block 22, and can be used with a wrench to make the bolt post 23 exert greater compressive force on the elastic pressure block 24.

[0022] The working principle of this utility model is as follows: When using this utility model, the loop body 41 of the loop 4 is inserted under the knitting disc of the circular knitting machine, and the outer wall of the loop body 41 is made to fit against one side of the fixing block 11 of the fixing base 1. The fixing block 11 has a groove with the same curvature as the loop body 41 on the side that fits against the loop body 41, so that the loop body 41 can fit fully against one side of the fixing block 11. When it is necessary to adjust the angle of the knitting disc, simply rotate the knitting disc, and the loop body 41 fixed on the knitting disc will rotate synchronously. During the rotation of the knitting disc, observation can be made through the observation port 12. Several scale marks 42 formed on the outer wall of the loop body 41 can be easily observed through the observation port 12. During the rotation, the rotation angle is determined by observing the scale marks 42, thereby accurately controlling the rotation angle. After adjusting to the appropriate angle, the rotation is stopped and the knitting disc is fixed. When adjusting the angle, the observation port 12 and the scale marks 42 can be used for convenient observation. The angle adjustment is controllable and highly accurate. No measuring tools are required for adjustment, making it convenient to use.
