Description

Gripper for gripper head of sample loom

Technical Field

The utility model belongs to the technical field of weaving equipment, especially, relate to a sample loom sword head holder.

Background

The sample loom is also called a sample loom, and the sample loom for making fabric is used in the design of woven fabric product. The weaving machine has two types, namely a manual weaving machine and an automatic weaving machine, is provided with 16 pages of heald frames, and can process fabrics with complex structures but smaller breadth. The former works, except for the warp shedding motion, the fabric formation is done manually. The weft density on the fabric machine is manually controlled, and because the winding quality of a weaving shaft is poor and the warp and weft density of the fabric is not tightly controlled, the processed fabric sample has a large difference from the fabric produced formally, and can only be used for predicting the performance and style of the designed fabric. The warp and weft density and the performance style of the fabric processed by the latter are closer to those of the fabric produced formally.

The rapier gripper is mounted on a sample loom and is matched with a yarn hooking rod to realize the traction of weft yarns, but the size of a gap between the yarn hooking rod and the yarn clamping surface of the existing rapier gripper cannot be adjusted, so that the rapier gripper can only be suitable for the traction of weft yarns with standard thickness, and when weft yarns with special thickness or special thickness are encountered, the rapier gripper cannot provide a proper holding force according to the situation, so that the rapier gripper is difficult to pick up, and a lot of inconvenience is brought to the use of the sample loom.

SUMMERY OF THE UTILITY MODEL

Detailed Description

In order to better understand the purpose, structure and function of the present invention, the gripper for gripper head of sample loom of the present invention is described in detail below with reference to the accompanying drawings.

As shown in fig. 1-3, a gripper for gripper head of sample loom comprises a shell 3, a hook-shaped yarn hooking rod 4 is arranged on the shell 3, a yarn clamping rod 1 is hinged on the yarn hooking rod 4, a reset spring 5 is arranged at the tail end of the yarn clamping rod 1, a fixed clamping surface of a hook part of the yarn hooking rod 4 and a movable clamping surface at the front end of the yarn clamping rod 1 are matched with each other to clamp weft yarn, an adjusting screw 2 is connected to the shell 3 in a threaded manner, the adjusting screw 2 is configured to adjust the minimum distance between the fixed clamping surface and the movable clamping surface, and a reinforcing component is arranged between the movable clamping surface and the fixed clamping surface.

When the sample loom is used, the rapier gripper moves in a reciprocating manner to realize the traction of weft yarns, external force pushes the tail end of the yarn clamping rod 1 to rotate the yarn clamping rod 1, the fixed clamping surface and the movable clamping surface are separated, the weft yarns can be clamped between the fixed clamping surface and the movable clamping surface, then the acting force on the tail end of the yarn clamping rod 1 is cancelled, the yarn clamping rod 1 is reset by the reset spring 5, the weft yarns are clamped by the yarn clamping rod 1 and the yarn hooking rod 4, the adjusting screw 2 is pressed against the tail end of the yarn clamping rod 1 by screwing the adjusting screw 2, the rotating range of the yarn clamping rod 1 is further controlled, the adjustment of the minimum clamping distance between the fixed clamping surface and the movable clamping surface is realized, the gripper can adjust proper clamping force according to the weft yarns with different thicknesses, the application range of the gripper is enlarged, and the fixed clamping surface and the movable clamping surface are rougher by the reinforcing assembly, the reliability of clamping the weft yarns is improved, and the weft yarns are effectively prevented from falling off.
