Description

Technical Field

[0001] This utility model belongs to the field of tension adjustment technology for warping machines, and specifically relates to an automatic tension adjustment device for warping machines. Background Technology

[0002] Warping machines are an important piece of equipment in the textile industry. They are mainly used to remove yarn from spindles or bobbins and arrange it neatly on warp beams or weaving beams to prepare for the subsequent weaving process. The main function of a warping machine is to wind a certain number of warp yarns parallel to each other on a warp beam or weaving beam according to a specified length and width, so that the warp yarns have uniform tension and are tightly wound on the warping beam in parallel, thus making preliminary preparations for the formation of the weaving beam.

[0003] Currently, warping machines are often equipped with tensioning devices to adjust the tension of the warp threads, reducing quality problems such as thread breakage and fuzz caused by unstable tension, thereby reducing downtime and improving production efficiency. However, the tensioning devices on current warping machines can only be kept in a fixed position, and the fasteners need to be removed before the position can be reselected for installation, which is complicated and inefficient.

[0022] 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.

[0023] Please see Figures 1 to 4 As shown, this utility model embodiment provides an automatic tension adjustment device for a warping machine, including a fixed platform 1 fixed to the upper surface of the warping machine. Fixed plates 2 are bolted to the left and right sides of the top of the fixed platform 1. Small cylinders 3 are mounted on opposite sides of the fixed plates 2, and a moving rod 4 is fixed to one end of the output shaft of each small cylinder 3. Adjusting rods 5 are hinged to the upper and lower sides of the moving rod 4. Tensioning rod bodies 7 are provided above and below the fixed plates 2, and mounting blocks 6 are rotatably connected to both ends of the tensioning rod bodies 7. A fixing groove 8 is formed on the top surface of the fixed platform 1, and an adjusting structure 9 is movably connected inside the fixing groove 8. Support frames 10 are fixed to the front and rear sides above the adjusting structure 9. A first antistatic fan 11 is fixed between the support frames 10, and a second antistatic fan 12 is provided on both the front and rear sides of the first antistatic fan 11. Specifically, in this embodiment, during use, the operator passes the warp thread through the tension rod bodies 7 on both sides and connects it to the warping machine below. When the operator needs to adjust the tension of the warp thread, they only need to open the small cylinders 3 on both sides. The output shaft of the small cylinders 3 pushes the moving rod 4 to move, thereby causing the adjusting rod 5 to move. The mounting block 6 drives the tension rod body 7 to move, and the upper and lower tension rod bodies 7 move in opposite directions, thereby adjusting the tension of the warp thread. If the operator needs to clean the dust on the surface of the tension rod body 7 after processing, they can turn on the motor 91 on one side and turn on the first antistatic fan 11 and the second antistatic fan 12. The first antistatic fan 11 and the second antistatic fan 12 move left and right below the tension rod body 7 to perform antistatic operation on the surface of the upper and lower tension rod bodies 7. Through the antistatic operation, the adsorption effect of static electricity on dust and impurities can be reduced, making it easier to clean the dust on the surface of the tension rod body 7, thereby improving cleaning efficiency.

[0024] Please see Figures 1 to 4 As shown, the adjusting rod 5 is inclined, with the end of the adjusting rod 5 away from the moving rod 4 hinged to the surface of the mounting block 6. A guide plate 13 is fixed to one side of the mounting block 6, and guide wheels 14 are rotatably connected to both the front and rear sides of the guide plate 13. Guide grooves 15 are provided on both the front and rear sides of the opposite side surface of the fixed plate 2, and the guide wheels 14 are rolled in connection with the inner wall of the guide grooves 15. When the small cylinder 3 is opened, the output shaft of the small cylinder 3 will drive the moving rod 4 to move left and right, causing the adjusting rod 5 to move. Through the arrangement of the guide plate 13, guide wheels 14 and guide grooves 15, the tensioning rod body 7 is guided, increasing the stability of the tensioning rod body 7 when adjusting the tension.

[0025] Please see Figures 1 to 4 As shown, the adjustment structure 9 includes a motor 91, a lead screw 92, and a moving block 93. The motor 91 is fixed to the right side of the fixed platform 1, and the output shaft of the motor 91 passes through the interior of the fixed groove 8. The lead screw 92 is rotatably connected inside the fixed groove 8. The right end of the lead screw 92 is fixedly connected to the output shaft of the motor 91. The moving block 93 is slidably connected to the middle of the inner wall of the fixed groove 8. The lead screw 92 passes through the moving block 93 and is threadedly connected to the moving block 93. The lower part of the support frame 10 is fixedly connected to the top of the moving block 93. Limiting grooves 16 are provided on the lower sides of the front and rear sides of the inner wall of the fixed groove 8. Limiting blocks 17 are fixed on the front and rear sides of the moving block 93. The limiting blocks 17 are located inside the limiting grooves 16 and are slidably connected to the inner wall of the limiting grooves 16. After the motor 91 is turned on, the output shaft of the motor 91 will drive the lead screw 92 to rotate, thereby causing the moving block 93 to move inside the fixed groove 8. The limiting blocks 17 also move inside the limiting grooves 16 to limit the moving block 93, so that the moving block 93 drives the first antistatic fan 11 and the second antistatic fan 12 to move left and right to perform antistatic operation on the tension rod body 7 above, so that the staff can clean the surface of the tension rod body 7 later.

[0026] In this embodiment, the top surface of the support frame 10 is inclined, and the second antistatic fan 12 is fixed on the inclined surface of the top of the support frame 10. The first antistatic fan 11 can perform antistatic operation on the surface of the tension rod body 7 located below, while the second antistatic fan 12, which is inclined on both sides, can perform antistatic operation on the surface of the tension rod body 7 above, so as to clean the tension rod body 7.
