Description

Technical Field

[0001] The utility model relates to the field of looms, in particular to a loom heald shaft structure. Background Technique

[0002] A loom is a device for weaving yarns, which can be divided into two categories: weaving and knitting. Weaving looms include primitive shuttle looms and new shuttleless looms. Shuttleless looms mainly include rapier looms, air jet looms, water jet looms and projectile looms.

[0003] The components of a loom are diverse, including the heald shaft. However, during the installation and use of the current heald shaft, it is difficult to adjust the overall length of the heald shaft, and its flexibility is poor when installing and adapting to looms of different specifications. Therefore, there are limitations in the assembly of the heald shaft. For this reason, we propose a loom heald shaft structure to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a loom heald shaft structure to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A loom heald shaft structure includes a heald shaft rod. Two heald shaft covers are slidably connected to the outer surface of the heald shaft rod. Two strip holes are opened on the mutually remote side surfaces of the two heald shaft covers. Fixing screws are arranged inside two groups of strip holes. Two groups of threaded grooves are opened on the outer surface of the heald shaft rod. Card slots are opened at the mutually remote ends of the two heald shaft covers. Internal threaded blocks are arranged inside the two card slots. Bearing seats are fixedly installed at the mutually remote ends of the two internal threaded blocks. Bearing mounting holes are opened on the outer surfaces of the two bearing seats.

[0007] In a further embodiment, threaded holes are opened on the inner walls of the two card slots. Locking screws are threadedly connected to the inner walls of the two threaded holes, and the outer surface of the locking screw is adapted to the inner wall of the internal threaded block.

[0008] In a further embodiment, limit holes are opened on the outer surfaces of the two heald shaft covers. Limit plates are fixedly connected to the outer surfaces of the two bearing seats. The bottom ends of the two limit plates respectively extend into the two limit holes.

[0009] In a further embodiment, a positioning groove is opened on the outer surface of the heald shaft rod. Positioning blocks are fixedly connected to the inner walls of the two heald shaft covers.

[0010] In a further embodiment, one end of each of the two positioning blocks close to each other extends into the interiors of the two positioning grooves respectively, and the outer surfaces of the two positioning blocks are respectively in contact with the inner walls of the two positioning grooves.

[0011] In a further embodiment, a model groove is formed on the outer surface of the heald shaft rod, and the outer surfaces of the two groups of fixing screws are respectively adapted to the inner walls of the two groups of threaded grooves.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] Through the cooperation of the heald shaft rod and the two heald shaft covers, the two heald shaft covers will slide up and down on the surface of the heald shaft rod. At the same time, by using the cooperation of the strip-shaped holes, the fixing screws and the threaded grooves, the heald shaft covers and the heald shaft rod can be firmly locked, and then the overall length of the heald shaft can be adjusted, making it more convenient and flexible to be installed and adapted to looms of different specifications, and improving the flexibility and installation speed of the heald shaft structure during assembly.

[0022] Please refer to Figures 1-4 , in the present utility model, a loom heald shaft structure includes a heald shaft rod 1. Two heald shaft covers 2 are slidably connected to the outer surface of the heald shaft rod 1. Two strip holes 6 are opened on one side surface of each of the two heald shaft covers 2 away from each other. Fixing screws 7 are provided inside both groups of strip holes 6. Two groups of threaded grooves 5 are opened on the outer surface of the heald shaft rod 1. Card slots 8 are opened at one end of each of the two heald shaft covers 2 away from each other. Internal threaded blocks 9 are provided inside both card slots 8. Bearing seats 14 are fixedly installed at one end of each of the two internal threaded blocks 9 away from each other. Bearing mounting holes 15 are opened on the outer surface of both bearing seats 14. Through the cooperation of the bearing seats 14 and the bearing mounting holes 15, the bearing assembly can be installed and it is convenient to assemble and adapt to the loom.

[0023] In a further embodiment, threaded holes 10 are formed in the inner walls of both of the two card slots 8. Locking screws 11 are threadedly connected to the inner walls of the two threaded holes 10, and the outer surface of each locking screw 11 is adapted to the inner wall of the internally threaded clamping block 9. Limiting holes 12 are formed in the outer surfaces of both of the two heddle shaft covers 2. Limiting plates 13 are fixedly connected to the outer surfaces of both of the two bearing seats 14. The bottom ends of the two limiting plates 13 respectively extend into the two limiting holes 12. Through the cooperation of the threaded holes 10 and the locking screws 11, the internally threaded clamping block 9 inside the card slot 8 can be tightly locked and fixed. By utilizing the limiting holes 12 and the limiting plates 13, a role of limiting and guiding is achieved during the installation of the bearing seat 14.

[0024] In a further embodiment, positioning grooves 3 are formed in the outer surface of the heddle shaft rod 1. Positioning blocks 4 are fixedly connected to the inner walls of both of the two heddle shaft covers 2.

[0025] The working principle of the present utility model is as follows: When the heddle shaft is used, first, the bearing seat 14 is taken, and one end of the internally threaded clamping block 9 is inserted into the card slot 8. Then, the locking screw 11 is rotated, and the locking screw 11 will rotate into the internally threaded clamping block 9, enabling quick locking and fixing of the bearing seat 14 during installation. Then, the fixing screw 7 is loosened according to the assembly length of the heddle shaft, and the two heddle shaft covers 2 will slide up and down on the surface of the heddle shaft rod 1. When the length between the heddle shaft cover 2 and the heddle shaft rod 1 is adjusted, the fixing screw 7 is rotated again, and the fixing screw 7 will rotate into the threaded groove 5, enabling firm locking and fixing between the heddle shaft cover 2 and the heddle shaft rod 1.
