Description

Technical Field

[0001] The utility model relates to the technical field of loom equipment, in particular to a fixing structure for a loom cloth-cutting electric heating wire. Background Art

[0002] The electric heating wire cloth-cutting mechanism of a loom cuts cloth through an electric heating wire. The problem existing in the electric heating wire cloth-cutting structure in the prior art is that the size of the electric heating wire changes before and after being electrified. After being electrified, the electric heating wire becomes longer, resulting in the electric heating wire being in a loose state and the cut cloth being uneven. In addition, for looms with a larger reed width specification, the fixing effect of the electric heating wire is not good. Content of the Utility Model

[0003] Aiming at the deficiencies existing in the prior art, the main purpose of the utility model is to provide an electric heating wire cloth-cutting mechanism that can make the electric heating wire in a tensioned state and can increase the width of the cloth cut by the electric heating wire under the same reed width size requirement.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A fixing structure for a loom cloth-cutting electric heating wire, including an electric heating wire support rod. An end support assembly is arranged at one end of the electric heating wire support rod. The end support assembly is fixedly connected with an electric heating wire. One end of the electric heating wire opposite to the end support assembly is connected with a steel wire rope through a joint fixing assembly. A steering assembly in contact connection with the steel wire rope is arranged at the other end of the electric heating wire support rod. The steering assembly includes a roller in contact with the steel wire rope. An expansion compensation assembly connected with the end of the steel wire rope is also arranged on the electric heating wire support rod.

[0005] Preferably, the expansion compensation assembly includes a spring connected with the end of the steel wire rope and a short clamping plate sleeve sleeved on the electric heating wire support rod. The short clamping plate sleeve is locked on the electric heating wire support rod through a first bolt and a first nut. One end of the spring opposite to the steel wire rope is hooked on the first bolt.

[0006] Preferably, the end support assembly includes an end clamping plate sleeve sleeved on the electric heating wire support rod. The end clamping plate sleeve is locked on the electric heating wire support rod through a second bolt and a second nut. The electric heating wire is clamped and fixed in the middle of the end clamping plate sleeve.

[0007] Preferably, the joint fixing assembly includes a joint bolt, two flat washers sleeved on the joint bolt, and a joint nut connected with the joint bolt. The ends of the electric heating wire and the steel wire rope are respectively clamped and fixed between the two flat washers by the joint bolt and the joint nut.

[0008] Preferably, the steering assembly includes a long splint sleeve sleeved on the heating wire support rod, a third bolt and a third nut. Two splint flat washers and a ball bearing are sleeved on the third bolt. A roller is sleeved and fixed on the outer ring of the ball bearing. The third bolt and the third nut lock and fix the long splint sleeve, the two splint flat washers and the ball bearing.

[0009] Preferably, a wire rope shield, which is also fixed by the third bolt and the third nut, is further arranged on the long splint sleeve. The wire rope shield covers the roller.

[0010] The utility model has the following advantages compared with the prior art. The purpose of using the steering assembly to change the direction of the wire rope is to increase the width of the heating wire for cutting cloth under the same reed width size requirement. The purpose of adding the telescopic compensation assembly is that after the heating wire is electrified and heated, the length dimension increases. The increased length of the heating wire at high temperature is absorbed by the spring. After cooling, the heating wire retracts to the original size, ensuring that the heating wire is always in a tensioned state. For looms with a large reed width specification.

[0018] The present utility model will be further described below in conjunction with the accompanying drawings.

[0019] As Figure 1 shown, a fixing structure for a fabric cutting electric wire of a loom includes an electric wire support rod 1. One end of the electric wire support rod 1 is provided with an end support assembly 2. The end support assembly 2 is fixedly connected with an electric wire 11. One end of the electric wire 11 relative to the end support assembly 2 is connected with a steel wire rope 34 through a joint fixing assembly 3. The other end of the electric wire support rod 1 is provided with a steering assembly 4 in contact connection with the steel wire rope 34. The steering assembly 4 includes a roller 46 in contact with the steel wire rope 34. The electric wire support rod 1 is further provided with a telescopic compensation assembly 5 connected to the end of the steel wire rope 34.

[0020] The purpose of using the steering assembly 4 to change the direction of the steel wire rope 34 is to increase the width of the fabric cut by the electric wire 11 under the same reed width size requirement. The purpose of adding the telescopic compensation assembly 5 is that after the electric wire 11 is energized and heated, its length dimension increases. The increased length of the electric wire 11 at high temperature is absorbed by the spring 51. After cooling, the electric wire 11 retracts to its original size, ensuring that the electric wire 11 is always in a tensioned state. For looms with a larger reed width specification, the present solution uses the section support assembly 2 to fix one end of the electric wire 11.

[0021] Preferably, the telescopic compensation assembly 5 includes a spring 51 connected to the end of the steel wire rope 34 and a short clamping plate sleeve 52 sleeved on the electric wire support rod 1. The short clamping plate sleeve 52 is locked on the electric wire support rod 1 through a first bolt 53 and a first nut 54. One end of the spring 51 relative to the steel wire rope 34 is hooked on the first bolt 53.

[0022] Both ends of the spring 51 are respectively hooked on the steel wire rope 34 and the first bolt 53, and after the spring 51 is heated, it can absorb the increased length of the electric wire 11 after thermal expansion deformation.

[0023] Preferably, the end support assembly 2 includes an end clamping plate sleeve 21 sleeved on the electric wire support rod 1. The end clamping plate sleeve 21 is locked on the electric wire support rod 1 through a second bolt 22 and a second nut 23. The electric wire 11 is clamped and fixed in the middle of the end clamping plate sleeve 21.

[0024] The purpose of setting the end support assembly 2 is to fix the electric wire 11.

[0025] Preferably, the joint fixing assembly 3 includes a joint bolt 31, two flat washers 32 sleeved on the joint bolt 31, and a joint nut 33 connected to the joint bolt 31. The ends of the electric wire 11 and the steel wire rope 34 are respectively clamped and fixed between the two flat washers 32 by the joint bolt 31 and the joint nut 33.

[0026] The joint fixing assembly 3 tightly fixes the wire rope 34 and the heating wire 11, which is convenient to operate and has a good structural fastening effect.

[0027] Preferably, the steering assembly 4 includes a long splint sleeve 41 sleeved on the heating wire support rod 1, a third bolt 42 and a third nut 43. Two splint flat washers 44 and a ball bearing 45 are sleeved on the third bolt 42. A roller 46 is sleeved and fixed on the outer ring of the ball bearing 45. The third bolt 42 and the third nut 43 lock and fix the long splint sleeve 41, the two splint flat washers 44 and the ball bearing 45.

[0028] Preferably, a wire rope shield 47 which is also fixed by the third bolt 42 and the third nut 43 is further arranged on the long splint sleeve 41. The wire rope shield 47 covers the roller 46.

[0029] The wire rope shield 47 is used to protect the wire rope 34 and the roller 46 to prevent foreign objects from entering and causing jamming.

[0030] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
