Description

Technical Field

[0001] The present invention relates to the field of textile machinery, in particular to a high-speed weaving machine. Background Art

[0002] like Figure 1 and 2 The above-mentioned technical solution is a prior application of the applicant (Patent No.: 201911098547.9), which discloses a braiding machine capable of achieving twisted weaving, comprising two heald frames, a front and rear heald frame, an opening drive box for driving the front heald frame to move left and right, and a starting heald box for driving the two heald frames to move up and down. The above-mentioned solution has the following defects:

[0003] 1. The heald box includes a gear transmission and speed change structure for changing the speed of the loom's main drive motor and transmitting it to the swing mechanism in the heald box. The swing mechanism is used to drive the two heald rods to rotate and swing back and forth within a certain range, and then drive the front and rear heald frames to achieve up and down movement through adapters. However, in the above solution, the swing mechanism and the heald rods are arranged in the same plane, which makes the heald box occupy a large area as a whole and is not conducive to being integrated with the loom frame. At the same time, in the above solution, the translational motion of the output rod in the swing mechanism is converted into reciprocating rotation of the heald rods, and then the rotation is converted into up and down motion through the adapter, resulting in an indirect output of the driving force.

[0004] 2. The power transmission structure between the loom's main drive motor, shedding drive box, and heald box is relatively complex, which leads to time-consuming installation, high maintenance frequency, and high costs.

[0005] 3. The loom is equipped with a take-up roller and an elastic roller. These two rollers work together through speed changes to adjust the tightness of the fabric during weaving and conveying. However, the power of the existing take-up roller and elastic roller is provided by the loom's main drive motor. Since the loom main drive also needs to provide power to the shedding drive box, heald box, etc., the transmission structure has the defects of complex design and difficult speed change. As the loom speed continues to increase, the transmission and speed change structure of the take-up roller and elastic roller no longer meets the requirements of new looms.
