Description

Technical Field

[0001] The utility model relates to the technical field of circular looms, in particular to a servo lifting mechanism of a circular loom. Background Art

[0002] A circular loom refers to an industrial device for weaving tubular fabrics. There are many yarn spindles on the warp beam of the circular loom. According to the width of the woven fabric and the width of the flat yarn, a specified number of warp yarns are used. Before the warp yarns enter the circular loom, the warp yarns are crossed and opened by the heddle frame of the warp yarns. The weft shuttle moves in a circular motion through the crossed opening among the warp yarns to weave into a tubular fabric.

[0003] After consulting the literature, it is known that the currently published patent: a Chinese utility model patent of a top extraction roller mechanism for a circular loom for producing woven bags, CN216809103U, includes a support plate, a driving mechanism, an embossing roller and a rubber roller. The embossing roller and the rubber roller are connected in a split drive. The tubular woven bag woven by the circular loom passes through the gap between the rubber roller and the embossing roller, and then winds around the top of the embossing roller and is conveyed backward to a winding device; the driving mechanism is arranged on the frame and drives the rubber roller to rotate. Both ends of the rubber roller and the embossing roller are installed on the support plate through bearing seats, and the support plate is vertically connected to the frame.

[0004] However, the following problems will still occur during the use of this device: Although the above technology solves the problem of the top extraction roller mechanism of the circular loom for producing woven bags, which is convenient for increasing the friction during the lifting process of woven bag production, preventing the woven bag from slipping, ensuring uniform lifting speed, and improving production efficiency, there are still problems in its actual use. Since in the existing patent, the rubber roller and the embossing roller are driven by a servo motor to rotate during the working process, and the rubber roller and the embossing roller are connected in a meshing manner through gears to rotate synchronously. However, in actual use, since the thickness of the woven fabric that the circular loom can produce is diverse, in order to better adapt to different thicknesses of woven fabrics and ensure the stability of the woven fabric during the lifting and transmission processes, it is necessary to replace the appropriate roller shafts. However, due to the high height of the mounting frame of the circular loom, it may be necessary to stop the machine and the staff climb to a higher place for replacement during actual replacement, which may reduce the efficiency of continuous work and increase the work intensity.

The bottom of the fixed cylinder rotates through the inside of the bottom device box. One side of the fixed cylinder located inside the bottom device box is fixedly connected to a third tapered gear. The end of the bottom rotating rod extending into the bottom device box is rotatably connected to the right inner wall of the bottom device box.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) When the distance between the embossing roller and the rubber roller needs to be adjusted according to the thickness of the woven cloth, the servo lifting mechanism of the circular loom first moves the top device box downward through the moving mechanism. During the movement, the sliding rod synchronously slides into the fixed cylinder, and drives the top rotating rod to move the embossing roller downward and adjust it to a suitable angle. After the top device box is moved, the servo motor works again, and the bottom rubber roller still rotates synchronously with the embossing roller in the opposite direction. Through the above method, the distance between the rubber roller and the embossing roller can be adjusted without affecting the rotation of the two rollers, thereby avoiding the need for workers to go to a high place to replace the roller shaft, thereby improving the production efficiency of the device for uninterrupted processing, reducing the work intensity of the workers, and minimizing the production cost.

[0015] (2) The servo lifting mechanism of the circular loom may generate a lot of flying flowers during the production and processing of the circular loom. When the sleeve rod moves, it drives the two filter plates to move synchronously and block the flying flowers in the air, so as to prevent the flying flowers from entering the cavity and affecting the operation of the motor. When the filter plate slides into the second slide groove, the flying flowers blocked by the filter plate will be scraped off by the inner wall of the groove. In the above manner, the device box and the filter plate are used to minimize the influence of the flying flowers generated during the production process on the operation of the device, thereby improving the stability of the device.

[0030] Please refer to Figure 1-8, the present utility model provides a technical solution: a servo lifting mechanism for a circular loom, including two support frames 1. Between the two support frames 1, two rotating rods 7 are arranged. The two rotating rods 7 are arranged in parallel alignment up and down. An embossing roller 3 is sleeved outside the top rotating rod 7, and a rubber roller 4 is sleeved outside the bottom rotating rod 7. The tubular woven fabric 2 woven by the circular loom passes through the gap between the rubber roller 4 and the embossing roller 3, and then winds around the top of the embossing roller 3 and is conveyed backward to the winding device. The embossing roller 3 and the rubber roller 4 are both existing structures in the existing patent: CN216809103U, and will not be elaborated here. The left end of the bottom rotating rod 7 is rotatably connected to one side of the left support frame 1. A rotation limiting mechanism is arranged on the left support frame 1, and a moving mechanism is arranged on the right support frame 1. On the right side of both rotating rods 7, there are device boxes 5. The inside of the device box 5 is hollow. One side of the rotating rod 7 close to the device box 5 rotates through the inside of the device box 5. The right inner wall of the top device box 5 is fixedly connected with a servo motor 10. The output end of the servo motor 10 is fixedly connected to one end of the top rotating rod 7 located inside the device box 5 on the same side. On the outer surface of one end of the top rotating rod 7 located inside the device box 5 on the same side, a tapered gear 21 is fixedly sleeved. Inside the top device box 5, there is a sliding rod 16. A second tapered gear 22 is fixedly sleeved on the top of the sliding rod 16. The second tapered gear 22 is meshed with the tapered gear 21. The bottom end of the sliding rod 16 rotates through the inside of the top device box 5. Between the two device boxes 5, there is a fixed cylinder 6. Inside the fixed cylinder 6, there are two groups of second limiting mechanisms. The inside of the fixed cylinder 6 is hollow. The bottom end of the sliding rod 16 slides through the inside of the fixed cylinder 6. On the front and rear outer surfaces of the sliding rod 16, there are convex blocks 17 fixedly connected. Inside the fixed cylinder 6, there are two grooves 19 matching the convex blocks 17. The two convex blocks 17 respectively extend into the two grooves 19 and slide with the grooves 19. The bottom of the fixed cylinder 6 rotates through the inside of the bottom device box 5. One side of the fixed cylinder 6 located inside the bottom device box 5 is fixedly connected with a third tapered gear 23. The end of the bottom rotating rod 7 extending into the bottom device box 5 is rotatably connected to the right inner wall of the bottom device box 5. On the outer surface of one end of the bottom rotating rod 7 located inside the bottom device box 5, a fourth tapered gear 24 is fixedly sleeved. The fourth tapered gear 24 and the tapered gear 21 are arranged in relative parallel. The fourth tapered gear 24 is meshed with the third tapered gear 23.During normal operation, the output end of the servo motor 10 in the top device box 5 drives the top rotating rod 7 to rotate, so that the bevel gear 21 drives the sliding rod 16 to rotate through the second bevel gear 22. The protrusion 17 of the sliding rod 16 located in the fixed cylinder 6 is restricted by the groove 19, so that when the sliding rod 16 rotates, it drives the fixed cylinder 6 to rotate synchronously. The fixed cylinder 6 rotates to make the third bevel gear 23 drive the bottom rotating rod 7 to rotate through the fourth bevel gear 24. Since the fourth bevel gear 24 is relatively parallel to the bevel gear 21, the bevel gear 21 and the fourth bevel gear 24 perform circular motion in opposite directions when rotating and keep synchronization. When it is necessary to adjust the distance between the embossing roller 3 and the rubber roller 4 according to the thickness of the woven cloth 2, the top device box 5 is first moved downward by the moving mechanism. During the movement, the sliding rod 16 slides synchronously into the fixed cylinder 6, and drives the top rotating rod 7 to move the embossing roller 3 downward and adjust it to a suitable angle. After the top device box 5 is moved, the servo motor 10 works again, and the bottom rubber roller 4 still rotates synchronously with the embossing roller 3 in the opposite direction.

[0031] Furthermore, the rotation limiting mechanism includes a slide groove 9, which is opened on the side of the left support frame 1 away from the embossing roller 3, and a displacement block 8 is arranged in the slide groove 9. One end of the top rotating rod 7 away from the top device box 5 is rotatably connected to the surface of the displacement block 8.

[0032] Furthermore, two limit grooves 15 are provided in the slide groove 9, and the two limit grooves 15 are respectively arranged on the front and rear sides of the displacement block 8. The side of the displacement block 8 close to the limit groove 15 extends into the limit groove 15 and slides with the limit groove 15. A spring 14 is fixedly connected between the bottom of the side of the displacement block 8 extending into the limit groove 15 and the inner wall of the limit groove 15. When the top device box 5 moves, the top rotating rod 7 drives the displacement block 8 to move synchronously along the slide groove 9, and the limit groove 15 limits the displacement angle of the displacement block 8 to avoid displacement of the displacement block 8 as much as possible when it moves.

[0033] Furthermore, the moving mechanism includes a cavity 26, which is opened inside the right support frame 1. The bottom inner wall of the cavity 26 is fixedly connected to a motor 13, and the output end of the motor 13 is fixedly connected to a threaded rod 12. The other end of the threaded rod 12 is rotatably connected to the top inner wall of the cavity 26, and the outer surface of the threaded rod 12 is threadedly sleeved with a sleeve rod 11.

[0034] Furthermore, a through slot is provided on the right support frame 1, and the left side of the sleeve rod 11 extends into the through slot and is fixedly connected to the right surface of the top device box 5 through the through slot provided on the right support frame 1. When the motor 13 is turned on, the output end of the motor 13 drives the threaded rod 12 to rotate. When the threaded rod 12 rotates, the sleeve rod 11 is restricted by the through slot, so when the threaded rod 12 rotates, it moves horizontally up and down, and when the sleeve rod 11 moves, it drives the top device box 5 to move synchronously.

[0035] Furthermore, two second chutes 25 are provided on the right support frame 1, and the two second chutes 25 are respectively arranged on the upper and lower sides of the sleeve rod 11, and the upper and lower sides of the sleeve rod 11 are fixedly connected with filter plates 27, and the opposite sides of the two filter plates 27 slide through the interior of the right support frame 1, and extend into the second chutes 25 and slide with the second chutes 25. During the production and processing of the circular loom, a lot of flying flowers may be generated. When the sleeve rod 11 moves, the two filter plates 27 are driven to move synchronously, and the flying flowers in the air are blocked, and the flying flowers are prevented from entering the cavity 26 as much as possible to affect the operation of the motor 13. When the filter plate 27 slides into the second chutes 25, the flying flowers blocked by the filter plate 27 will be scraped off by the inner wall of the through groove.

[0036] Furthermore, the two sets of second limiting mechanisms include limiting blocks 18, which are respectively fixedly connected to the left and right outer surfaces of the sliding rod 16, and two limiting grooves 20 are provided in the fixed cylinder 6, which are respectively arranged on the left and right sides of the sliding rod 16 and are kept parallel to the two limiting blocks 18, and the farthest sides of the two limiting blocks 18 extend into the limiting grooves 20 on the same side and slide with the limiting grooves 20. When the sliding rod 16 slides in the fixed cylinder 6, the limiting blocks 18 are driven to slide synchronously along the limiting grooves 20, and the slidable distance of the sliding rod 16 is limited to prevent the sliding rod 16 from sliding out of the fixed cylinder 6.

[0037] Working principle: In normal operation, the output end of the servo motor 10 in the top device box 5 drives the top rotating rod 7 to rotate, so that the bevel gear 21 drives the sliding rod 16 to rotate through the second bevel gear 22. The protrusion 17 of the sliding rod 16 located in the fixed cylinder 6 is restricted by the groove 19, so that when the sliding rod 16 rotates, it drives the fixed cylinder 6 to rotate synchronously. The rotation of the fixed cylinder 6 causes the third bevel gear 23 to drive the bottom rotating rod 7 to rotate through the fourth bevel gear 24. Since the fourth bevel gear 24 is relatively parallel to the bevel gear 21, the bevel gear 21 and the fourth bevel gear 24 perform circular motion in opposite directions when rotating and keep synchronization. When it is necessary to adjust the distance between the embossing roller 3 and the rubber roller 4 according to the thickness of the woven cloth 2, the top device box 5 is first moved downward by the moving mechanism. During the movement, the sliding rod 16 slides synchronously into the fixed cylinder 6, and drives the top rotating rod 7 to move the embossing roller 3 downward and adjust it to a suitable angle. After the top device box 5 is moved, the servo motor 10 works again, and the bottom rubber roller 4 is still with the embossing roller 3. The top device box 5 moves synchronously in the opposite direction. When the top device box 5 moves, the top rotating rod 7 drives the displacement block 8 to move synchronously along the slide groove 9, and the limit groove 15 limits the displacement angle of the displacement block 8 to avoid displacement when the displacement block 8 moves. Turn on the motor 13, and the output end of the motor 13 drives the threaded rod 12 to rotate. When the threaded rod 12 rotates, the sleeve rod 11 is restricted by the through groove, so when the threaded rod 12 rotates, it will move up and down horizontally. When the sleeve rod 11 moves, it drives the top device box 5 to move synchronously. In the production and processing of the circular loom, A lot of flying flowers may be generated. When the sleeve rod 11 moves, the two filter plates 27 are driven to move synchronously and block the flying flowers in the air, trying to prevent the flying flowers from entering the cavity 26 and affecting the operation of the motor 13. When the filter plate 27 slides into the second slide groove 25, the flying flowers blocked by the filter plate 27 will be scraped off by the inner wall of the through groove. When the sliding rod 16 slides in the fixed cylinder 6, the limit block 18 is driven to slide synchronously along the limit groove 20 and limit the sliding distance of the sliding rod 16 to prevent the sliding rod 16 from sliding out of the fixed cylinder 6.

[0038] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
