Description

Technical Field

[0001] The utility model relates to the technical field of loom equipment, in particular to a driving and transmission component of a cloth cutting mechanism of a loom. Background Art

[0002] During the weaving process, after the fabric is wound to a certain length, it must be cut manually. This process requires the machine to stop, placing a heavy burden on workers and reducing production efficiency. Furthermore, manual cutting cannot be performed to trim the edges, which affects the appearance of the fabric. Therefore, the use of heated wires for high-temperature fabric cutting has gained attention, and the design of the drive and transmission components that drive the heated wires to achieve fabric cutting is particularly important. Utility Model Content

[0003] In view of the shortcomings of the prior art, the main purpose of the present invention is to provide a driving and transmission assembly of a loom cloth cutting mechanism that can stably drive the electric heating wire to perform periodic swing.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a driving and transmission assembly of a cloth cutting mechanism of a loom, comprising an upper wall panel and a lower wall panel, comprising a heating wire support rod for fixing the heating wire, one end of the heating wire support rod is connected to an end bearing seat, the end bearing seat is fixed to the upper wall panel through a support frame, a cloth cutting motor seat is provided on the lower wall panel, a servo motor is fixedly provided on the cloth cutting motor seat, the output shaft of the servo motor is connected to a worm, a heating wire support bearing seat is fixedly provided on the cloth cutting motor seat, the other end of the heating wire support rod passes through the heating wire support bearing seat and is fixedly connected to a worm gear, and the worm gear is meshed with the worm gear.

[0005] Preferably, a front cover shell and a rear cover shell capable of covering the servo motor, the worm and the worm wheel are fixedly connected to the cloth cutting motor seat by bolts.

[0006] Preferably, the heating wire support rod is fixedly connected to the heating wire support bearing seat through a bushing.

[0007] Preferably, the servo motor is fixed to the cloth cutting motor base by four bolts.

[0008] This utility model offers the following advantages over existing technologies: the periodic oscillation of the servo motor's output shaft, through the meshing transmission of the worm gear and worm, changes its direction of rotation and drives the heating wire support rod to oscillate periodically. This oscillation moves the heating wire from a distance from the fabric to contact with it, returning it to its starting point after the fabric is cut. As the heating wire approaches the fabric, it is energized and heated, and upon contact with the fabric, the high temperature is used to sever the fabric. This solution can improve the automation of the fabric cutting process on the loom, reduce the operator's burden, and improve production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The present invention will be further described below with reference to the accompanying drawings.

[0014] like Figure 1 As shown, a driving and transmission assembly of a cloth cutting mechanism of a loom comprises an upper wall panel 1 and a lower wall panel 2, and a heating wire support rod 3 for fixing the heating wire, one end of the heating wire support rod 3 is connected to an end bearing seat 4, and the end bearing seat 4 is fixed to the upper wall panel 1 through a support frame 5, a cloth cutting motor seat 6 is provided on the lower wall panel 2, a servo motor 7 is fixedly provided on the cloth cutting motor seat 6, an output shaft of the servo motor 7 is connected to a worm 8, a heating wire support bearing seat 9 is fixedly provided on the cloth cutting motor seat 6, the other end of the heating wire support rod 3 passes through the heating wire support bearing seat 9 and is fixedly connected to a worm gear 10, and the worm gear 10 is meshed with the worm gear 8.

[0015] The present invention provides a driving and transmission component of a cloth cutting mechanism of a loom, wherein the heating wire support rod 3 is fixedly connected to the heating wire, and the method of fixing the heating wire and the heating wire support rod 3 is not limited in this invention, the worm 8 is fixed to the output shaft of the servo motor 7 by a set screw, the servo motor 7 is fixed to the cloth cutting motor seat 6 by four bolts, the front cover 11 and the rear cover 12 are each fixed to the cloth cutting motor seat 6 by two bolts, and the cloth cutting motor seat 6 is fixed to the lower wall panel 2 of the loom by a combination of two groups of bolts and gaskets; the right side of the heating wire support rod 3 passes through the heating wire support bearing seat 9 and the worm gear 10 in sequence, wherein the worm gear 10 is fixed to the heating wire support rod 3 by a set screw and engages with the worm 8 to form a worm 8 transmission, the heating wire support bearing seat 9 cooperates with the heating wire support rod 3 through the bushing 13, and the heating wire support bearing seat 9 is fixed to the cloth cutting motor seat 6 by four bolts.
