Description

Technical Field

[0001] This utility model relates to the field of rapier loom technology, specifically a traction device for rapier looms. Background Technology

[0002] Rapier looms, as the most widely used shuttleless looms, are characterized by high speed, high automation, and high-efficiency production. Their active weft insertion method can adapt to various types of yarns, offering significant advantages in multi-color weft weaving, capable of producing yarn-dyed products with up to 16 weft colors. As shuttleless looms gradually replace shuttle looms, rapier looms are playing an increasingly important role in woven fabric production.

[0003] Publication No. 202421431842.8 discloses a traction device for a rapier loom, including a positioning plate. Sliding blocks are arranged on both the front and rear sides of one side of the positioning plate. A first lead screw is threaded onto the bottom of each sliding block, and a first knob is fixedly installed on the bottom of the first lead screw. A fixing frame is fixedly installed between the sides of the sliding blocks. In the above-disclosed patent, when the springs are used for a long time, they are prone to fatigue and damage. When different specifications of springs need to be replaced according to different working conditions, extensive disassembly of the entire equipment is often required. This is not only cumbersome and time-consuming, but also may damage other parts of the equipment due to frequent disassembly, increasing maintenance costs and equipment downtime, and reducing production efficiency. Therefore, this traction device for a rapier loom is proposed to solve the above problems. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please refer to Figure 1-3 As shown, this utility model provides a traction device for a rapier loom, including a mounting plate 1 and a connecting plate 2. The connecting plate 2 is disposed at the lower end of the mounting plate 1. Through holes are opened at both ends of the surface of the mounting plate 1. Slide rods 12 are installed at both ends of the upper surface of the connecting plate 2. The upper end of the slide rods 12 extends upward through the through holes opened on the surface of the mounting plate 1. An adjustment component is installed on the upper surface at the center of the connecting plate 2. A limit component is provided on the outer side of the slide rods 12.

[0019] Specifically, when a spring is completely damaged and needs to be replaced, this device only requires unscrewing the hex socket bolt 10 and nut 8, removing the pressure plate 3, and then easily removing and replacing the first spring 4 and the second spring 5. This reduces the overall disassembly of the equipment, minimizes damage to other components, saves maintenance costs and downtime, and improves production efficiency. When the springs become fatigued or lack elasticity, there is no need for complicated disassembly. By pressing down the pressure plate 3, rotating the nut 8, and changing the screw position of the hex socket bolt 10, the elasticity of the first spring 4 and the second spring 5 can be quickly increased. The operation is simple, efficient, and saves time.

[0020] The limiting component includes a pressure plate 3, socket head cap screws 10, and threaded holes 11. Multiple sets of threaded holes 11 are arranged on the surfaces of the upper ends of the two sets of slide rods 12. Multiple sets of socket head cap screws 10 are threaded into the interior of the threaded holes 11. The pressure plate 3 is located on the outside of the two sets of slide rods 12 and is slidable. It is located at the lower end of the socket head cap screws 10. By unscrewing the socket head cap screws 10 from the threaded holes 11 and re-tightening them in another set of threaded holes 11, the pressure plate 3 and the two sets of slide rods 12 can be limited.

[0021] The adjusting component includes a screw 9 and a nut 8. The lower end of the screw 9 is fixedly installed on the upper surface of the mounting plate 1, and the upper end of the screw 9 extends upward through the pressure plate 3 and can slide inside the pressure plate 3. The nut 8 is threadedly connected to the surface of the screw 9 and is set at the upper end of the pressure plate 3. By pressing down the pressure plate 3, the first spring 4 and the second spring 5 are squeezed from below. Then, rotating the nut 8 can quickly increase the elasticity of the first spring 4 and the second spring 5. The operation is simple, efficient and time-saving.

[0022] Among them: a first spring 4 is installed on the outside of the screw 9. The upper end of the first spring 4 rests on the lower surface of the pressure plate 3, and its lower end rests on the lower surface of the mounting plate 1. A second spring 5 is provided on the outside of the two sets of slide rods 12. The upper end of the second spring 5 rests on the lower surface of the pressure plate 3, and its lower end rests on the lower surface of the mounting plate 1. The first spring 4 and the second spring 5 can increase the buffering effect during traction.

[0023] Wherein: a slot 13 is provided on one side of the connecting plate 2, a card plate 6 is installed inside the slot 13, and a connecting hook 7 is installed on the lower surface of the card plate 6. The connection between the slot 13 and the card plate 6 facilitates quick assembly and disassembly of the connecting hook 7.

[0024] Working principle: This utility model is a traction device for a rapier loom. First, when the springs become fatigued and lack elasticity, the first spring 4 and the second spring 5 can be squeezed by pressing down the pressure plate 3. Then, the nut 8 is rotated so that its lower end is tightly attached to the upper surface of the pressure plate 3. Then, the hexagonal socket bolt 10 is taken out from the inside of a set of threaded holes 11 and then tightened into another set of threaded holes 11 at the upper end of the pressure plate 3. This increases the elasticity of the first spring 4 and the second spring 5 and reduces costs. When the springs are completely damaged and need to be replaced, the hexagonal socket bolt 10 is unscrewed from the inside of the threaded holes 11, and then the nut 8 is unscrewed from the surface of the screw 9. Then, the pressure plate 3 is removed from the slide bar 12 and the clamping plate 6, and then the first spring 4 and the second spring 5 installed on its outside are taken out and replaced.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
