Description

Technical Field

[0001] The utility model relates to the technical field of knitting machines, in particular to a loop transfer jacquard structure of a knitting machine. Background Technique

[0002] A knitting machine is a device for producing fabrics. In order to improve the aesthetics of the fabrics, loop transfer jacquard operations are required. However, there are still certain defects in the existing loop transfer jacquard structures of knitting machines when in use.

[0003] During the use process, the loop transfer jacquard cam blocks of the knitting machine are directly locked on the sliders in the jacquard machine. The knitting needles rise and fall along the shape of the guide rails on the cam blocks. By adjusting the height of the cam blocks, the thickness of the fabric surface is controlled. After long-term friction between the existing cams and the knitting needles, high temperatures will be generated, and the high temperatures are difficult to dissipate, resulting in serious high-temperature wear of the cams, affecting the needle feeding effect, poor practicability, and reducing the service life of the overall machine;

[0004] In order to overcome the above defects, the prior art 1 (a Chinese patent with the application number CN202020747757.8 and the application date of May 8, 2020) a cam for a knitting machine with strong wear resistance, including a cam body. There are three mounting holes on the top of the cam body, and the three mounting holes are arranged in a triangle on the top of the cam body. By designing the three mounting holes to be arranged in a triangle on the top of the cam body, it is convenient to fix the cam body, and the fixing effect is good. By designing the heat dissipation holes, it is convenient for the heat inside the cam body to dissipate. There is a chute on the top of the cam body, and the chute is a trapezoidal wire groove. There are heat dissipation holes on the right side of the cam body. The heat dissipation holes can accelerate the dissipation of the heat inside the cam body through the air, thereby effectively reducing the temperature of the cam body, avoiding high-temperature wear, and having good wear resistance, so as to achieve the effect of strong wear resistance and solve the problem of poor wear resistance of the existing device;

[0005] Although the prior art can dissipate heat, during the working process, heat dissipation is carried out by arranging heat dissipation holes on the right side of the cam body. Operating the heat dissipation holes on the right side is inconvenient, and it is easy to cause uneven heat dispersion, thereby damaging the cam body, reducing the service life of the cam body, and when the cam body is in use, most of its heat is concentrated inside the needle feeding groove. Therefore, only arranging heat dissipation holes on the right side of the cam, the heat dissipation holes cannot quickly conduct the heat on the needle feeding groove surface, and thus cannot achieve rapid heat dissipation, and the practicability is poor.

[0006] In view of the above problems, it is urgent to innovate on the basis of the original loop transfer jacquard structure of the knitting machine. Therefore, we have proposed a loop transfer jacquard structure of the knitting machine that can well solve the above problems. Summary of the Utility Model

[0007] The utility model aims to provide a knitting machine transfer jacquard structure to solve the problem raised by the above-mentioned background technology that heat dissipation holes are set on the right side of the triangle body in the current market for heat dissipation, the heat dissipation holes on the right side are inconvenient to operate, and easily lead to uneven heat dispersion, thereby causing damage to the triangle body and reducing the service life of the triangle body. When the triangle body is in use, most of the heat is concentrated inside the needle groove. Therefore, only the heat dissipation holes are set on the right side of the triangle, and the heat dissipation holes cannot quickly dissipate the heat on the needle groove surface, thereby failing to achieve rapid heat dissipation and having poor practicality.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a knitting machine transfer jacquard structure, comprising a base, the base is connected to a storage seat through a fixing member;

[0009] A triangle seat is installed at the side end of the storage seat, and the triangle seat includes a needle outlet triangle, a half needle triangle and a flat needle triangle.

[0015] Preferably, an auxiliary seat is installed on the side end of the support seat, a positioning rod is provided on the upper end of the support seat, and a yarn feeding ring is installed on the positioning rod.

[0016] Preferably, a yarn feeding nozzle is connected to the side end of the positioning rod, and the yarn feeding nozzle corresponds to the position of the vertical knitting needles and the horizontal knitting needles.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows: for the loop transfer jacquard structure of this knitting machine, the heat inside the needle rail can be dispersed through the first heat dissipation groove, the second heat dissipation groove, and the third heat dissipation groove, and the first heat dissipation groove, the second heat dissipation groove, and the third heat dissipation groove are communicated with the needle rail, reducing the problem of reduced service life caused by the inability to dissipate heat quickly due to the one-sided opening of heat dissipation holes. The specific content is as follows:

[0018] (1) The stitch cam, half-stitch cam, and plain cam are effectively cooled through the first heat dissipation groove, the second heat dissipation groove, and the third heat dissipation groove penetrating internally, enabling the heat inside the needle rail to be dispersed through the first heat dissipation groove, the second heat dissipation groove, and the third heat dissipation groove, reducing the problem of low heat dissipation efficiency caused by one-sided heat dissipation;

[0019] (2) The needle rails of the stitch cam, half-stitch cam, and plain cam are arranged in a curve, which is smoother, reducing the pressure on the vertical needle shaft of the knitting needle during high-speed operation of the machine. Moreover, the slider on the object placement seat is independently designed, facilitating independent adjustment and movement of the cam holder, improving the overall practicality;

[0020] (3) The object placement seat and the vertical needle cylinder are connected only by the vertical knitting needles and the cam holder, not only reducing the deformation of the precision parts of the machine caused by high temperature, but also reducing the impact wear on the vertical knitting needles during high-speed operation, improving the service life of the vertical knitting needles;

[0021] (4) By arranging and combining the stitch cam, half-stitch cam, and plain cam, the overall jacquard efficiency is greatly improved, reducing the problem of reduced knitting practicality caused by operating with the same cam holder, and facilitating adjustment and installation according to requirements;

[0022] (5) The knitting thread is conveyed through the yarn feeding ring and the yarn feeding nozzle, enabling stable supply of the overall knitting thread for knitting, not only reducing the problem of damage caused by knotting of the knitting thread, improving the overall jacquard quality, but also reducing the inconvenience caused by the need to stop the machine for maintenance.
