Description

Technical Field

[0001] This utility model relates to the field of textile machinery and equipment, specifically to a head drive device for a double needle bed machine. Background Technology

[0002] In the current context of the continuous development of the textile industry, warp knitting machines, as important textile machinery, have attracted much attention for their technological iteration and product innovation. In recent years, with the significant improvement of residents' living standards, consumers' demands for warp-knitted products have become more refined and personalized, requiring not only high quality but also a wider variety of patterns and colors. Against this backdrop, the differences in warp knitting machines based on the number of needle beds have gradually become more prominent. Compared to single-needle-bed warp knitting machines, double-needle-bed warp knitting machines, with their ability to knit double-sided warp-knitted fabrics, cylindrical fabrics, and various plush fabrics, better meet the increasingly complex and diverse needs of the market with their rich and varied patterns and colors, thus gaining wider application in the industry.

[0003] From the structural composition of a warp knitting machine, the knitting mechanism, comb section traverse mechanism, warp feeding mechanism, take-up and pull-out mechanism, and transmission mechanism together constitute its core system. Among them, the transmission mechanism, as a key part to ensure the stable operation of the warp knitting machine, traditionally adopts a transmission mode composed of a driving pulley, a driven pulley, and a single synchronous belt. This transmission structure has obvious defects in practical applications: on the one hand, the single synchronous belt is prone to elongation and deformation during operation due to the load under different working conditions, which leads to a decrease in transmission accuracy and directly affects the overall operating accuracy of the warp knitting machine; on the other hand, with the long-term operation of the equipment, the wear of the single synchronous belt intensifies, posing a risk of sudden breakage. Once broken, it will not only damage the needles of the equipment and cause production accidents, but also require a complete recalibration of the equipment accuracy after replacing the synchronous belt. The whole process is cumbersome, time-consuming, and labor-intensive, seriously restricting the improvement of production efficiency and the economic benefits of enterprises. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical problems and provide a head drive device for a double needle bed equipment.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a double needle bed machine head transmission device, including a first rotating shaft, a second rotating shaft, a first transmission mechanism, and a second transmission mechanism. The first rotating shaft and the second rotating shaft are arranged opposite to each other, and the first transmission mechanism and the second transmission mechanism are both arranged between the first rotating shaft and the second rotating shaft, and the first transmission mechanism and the second transmission mechanism are arranged opposite to each other at intervals.

[0006] Furthermore, the first transmission mechanism includes a first driving pulley, a first driven pulley, and a first synchronous belt. The first driving pulley is disposed on the first rotating shaft, the first driven pulley is disposed on the second rotating shaft, and the first synchronous belt is sleeved on the first driving pulley and the first driven pulley so that the first driving pulley drives the first driven pulley to rotate.

[0007] Furthermore, the second transmission mechanism includes a second driving pulley, a second driven pulley, and a second synchronous belt. The second driving pulley is disposed on the first rotating shaft, the second driven pulley is disposed on the second rotating shaft, and the second synchronous belt is sleeved on the second driving pulley and the second driven pulley so that the second driving pulley drives the second driven pulley to rotate.

[0008] Furthermore, the first driving pulley, the first driven pulley, the second driving pulley, and the second driven pulley are V-type pulleys, and the first synchronous belt and the second synchronous belt are V-type belts.

[0009] Furthermore, a first pressing mechanism is provided above the first transmission mechanism, wherein the first pressing mechanism includes a first pressure roller, and the first pressure roller presses against the first synchronous belt.

[0010] Furthermore, a second pressing mechanism is provided above the second transmission mechanism.

[0011] Furthermore, the second pressing mechanism includes a second pressing base, a second pressing eccentric shaft, and a second pressing roller. The second pressing eccentric shaft is rotatably disposed on the second pressing base, the second pressing roller is disposed on the second pressing eccentric shaft, and the second pressing roller abuts against the second synchronous belt.

[0012] Furthermore, a tensioning mechanism is provided below the second transmission mechanism.

The tensioning eccentric shaft is rotatably mounted on the tensioning base, and the synchronous pulley is mounted on the tensioning eccentric shaft, with the synchronous pulley pressing against the second synchronous belt.

[0014] As can be seen from the above description of this utility model, compared with the prior art, the double needle bed machine head transmission device provided by this utility model has the following advantages: by setting up a first transmission mechanism and a second transmission mechanism with opposite intervals, a double synchronous belt transmission is realized. Even if one synchronous belt fails, the other can still maintain the operation of the equipment, avoiding sudden shutdown and equipment damage; and by using double synchronous belts to share the load, the elongation and deformation of a single synchronous belt can be reduced, improving transmission stability and accuracy, and ensuring the knitting quality of the warp knitting machine; at the same time, when it is necessary to replace the synchronous belt, one of them can be adjusted or replaced individually without recalibrating the accuracy of the entire equipment, reducing maintenance costs and time.
