Description

Technical Field

[0001] This utility model relates to the field of adjustment device technology, and in particular to a yarn tension adjustment device for a warping machine. Background Technology

[0002] Warping machines are key pieces of equipment in the textile industry used to wind yarn parallel to the warp beam. Their yarn tension adjustment devices directly affect the quality of the yarn and production efficiency. During the warping process, the yarn needs to maintain appropriate tension to ensure uniform winding and avoid slack or excessive tightness. If the tension is too high, the yarn is prone to breakage, leading to machine downtime for maintenance and material waste. If the tension is insufficient, the yarn is prone to pilling or tangling, affecting the quality of subsequent weaving.

[0003] The existing yarn tension adjustment devices for warping machines have poor flexibility in tension adjustment. The existing adjustment devices are usually fixed on the support frame and control the tension force by a single spring or lever. It is difficult to make fine adjustments according to different yarn types (such as cotton yarn and chemical fiber yarn) or process requirements, which leads to the tension not being able to adapt to changes. The yarn is prone to breakage due to excessive tension, which affects continuous production. Therefore, this needs to be improved. Utility Model Content

[0065] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a yarn tension adjustment device for a warping machine.

[0066] A yarn tension adjustment device for a warping machine includes a support frame 1 and a transmission roller 2, the transmission roller 2 being fixedly connected to the support frame 1; it also includes: a take-up roller 3, disposed on and fixedly connected to the support frame 1; a control box 4, disposed on and fixedly connected to the support frame 1; a support frame 5, disposed on and fixedly connected to the support frame 1; a lifting mechanism, disposed on the support frame 5, for squeezing the yarn; a lifting groove 6, formed on the support frame 5; a lifting block 7, disposed within the lifting groove 6 and slidably connected to the lifting groove 6; a lifting plate 8, fixedly connected to the lifting block 7; and two sets of elastic mechanisms, symmetrically arranged on the lifting plate 8, for adjusting the yarn tension.

[0067] Reference Figure 5In a preferred embodiment, the lifting mechanism includes: a lifting frame 9, which is disposed on the support frame 5 and fixedly connected to the support frame 5; a lifting motor 10, which is fixedly connected to the lifting frame 9; a lifting shaft 11, which is fixedly connected to the output end of the lifting motor 10 and rotatably connected to the support frame 5; and a sliding component, which is disposed on the support frame 5.

[0068] When in operation, the lifting motor 10 is started, which drives the lifting shaft 11, which is fixedly connected to the output end of the lifting motor 10, to rotate.

[0069] Reference Figure 2 and Figure 5 In a preferred embodiment, the sliding component includes: a sliding groove 12, which is formed on the support frame 5; two sliding blocks 13, which are symmetrically arranged in the sliding groove 12, slidably connected to the sliding groove 12, and threadedly connected to the lifting shaft 11; and a rotating component, which is disposed on the sliding blocks 13.

[0070] During operation, the sliding block 13, which is threadedly connected to the lifting shaft 11, rotates, causing the sliding block 13 to slide within the sliding groove 12, so that the sliding blocks 13 come into contact with each other.

[0071] Reference Figure 5 In a preferred embodiment, the rotating component includes: a first rotating shaft 14, which is disposed on the sliding block 13 and fixedly connected to the sliding block 13; a rotating plate 15, which is rotatably connected to the first rotating shaft 14; a second rotating shaft 16, which is disposed on the rotating plate 15 and rotatably connected to the rotating plate 15; and a rotating frame 17, which is fixedly connected to the second rotating shaft 16 and fixedly connected to the lifting plate 8.

[0072] During operation, the rotating plate 15, which is rotatably connected to the first rotating shaft 14, rotates, causing the rotating frame 17, which is fixedly connected to the second transmission shaft 24, to move closer to the support frame 1. This causes the lifting plate 8, which is fixedly connected to the rotating frame 17, to move, so that the lifting block 7, which is fixedly connected to the lifting plate 8, slides in the lifting groove 6, causing the rotating cylinder 31 to move closer to the surface of the yarn.

[0073] Reference Figure 4 In a preferred embodiment, the elastic mechanism includes: an elastic frame 18, disposed on the lifting plate 8 and fixedly connected to the lifting plate 8; a first elastic block 19, disposed on the lifting plate 8 and fixedly connected to the lifting plate 8; an elastic spring 20, disposed on the first elastic block 19 and fixedly connected to the first elastic block 19; a second elastic block 21, fixedly connected to the elastic spring 20; and a transmission component disposed on the first elastic block 19.

[0074] When in operation, the second elastic block 21 moves closer to the first elastic block 19, causing the elastic spring 20 to be compressed and generating elastic potential energy.

[0075] Reference Figure 4 In a preferred embodiment, the transmission component includes: two first transmission shafts 22, which are symmetrically arranged on and fixedly connected to the first elastic block 19; two first transmission plates 23, which are symmetrically arranged on and rotatably connected to the first transmission shafts 22; a second transmission shaft 24, which is rotatably connected to the first transmission plates 23; two third transmission shafts 25, which are symmetrically arranged on and fixedly connected to the second elastic block 21; a second transmission plate 26, one end of which is rotatably connected to the second transmission shaft 24 and the other end of which is rotatably connected to the third transmission shaft 25; and a connecting component disposed on the second transmission shaft 24.

[0076] During operation, the second transmission plate 26, which is rotatably connected to the second transmission shaft 24, rotates around the axis of the third transmission shaft 25, causing the first transmission plate 23, which is rotatably connected to the first transmission shaft 22, to rotate.

[0077] Reference Figure 4 In a preferred embodiment, the connecting component includes: a connecting frame 27, which is disposed on the second drive shaft 24 and fixedly connected to the second drive shaft 24; a connecting spring 28, one end of which is fixedly connected to the connecting frame 27 and the other end of which is fixedly connected to the elastic frame 18; and a rotating component, which is disposed on the second elastic block 21.

[0078] During operation, the connecting frame 27, which is fixedly connected to the second drive shaft 24, moves, causing the connecting spring 28, which is fixedly connected to the connecting frame 27, to be stretched, generating elastic potential energy.

[0079] Reference Figure 4 In a preferred embodiment, the rotating component includes: a rotating frame 29, which is disposed on the second elastic block 21 and fixedly connected to the second elastic block 21; a rotating shaft 30, which is fixedly connected to the rotating frame 29; a rotating cylinder 31, which is rotatably connected to the rotating shaft 30; and a pressure sensor 32, which is disposed on the rotating cylinder 31 and fixedly connected to the rotating cylinder 31.

[0080] During operation, the rotating drum 31 rotates around the axis of the rotating shaft 30, allowing the pressure sensor 32 on the rotating drum 31 to monitor the tension of the yarn in real time.

[0081] Working principle: In use, the yarn is first passed through the transmission roller 2 and placed on the take-up roller 3. Then, the lifting motor 10 is started, which drives the lifting shaft 11, which is fixedly connected to the output end of the lifting motor 10, to rotate. This causes the sliding block 13, which is threadedly connected to the lifting shaft 11, to rotate. The sliding block 13 slides in the sliding groove 12, causing the sliding blocks 13 to move closer to each other. This causes the rotating plate 15, which is rotatably connected to the first rotating shaft 14, to rotate. This causes the rotating frame 17, which is fixedly connected to the second transmission shaft 24, to move closer to the support frame 1. This causes the lifting plate 8, which is fixedly connected to the rotating frame 17, to move. This causes the lifting block 7, which is fixedly connected to the lifting plate 8, to slide in the lifting groove 6. This causes the rotating cylinder 31 to move closer to the surface of the yarn, thereby achieving the compression and tensioning of the yarn.

[0082] Then, when the rotating drum 31 contacts the yarn surface, it drives the rotating frame 29 to move closer to the elastic frame 18, causing the second elastic block 21, which is fixedly connected to the rotating frame 29, to move closer to the first elastic block 19. This causes the elastic spring 20 to be compressed, generating elastic potential energy. This causes the second transmission plate 26, which is rotatably connected to the second transmission shaft 24, to rotate around the axis of the third transmission shaft 25, causing the first transmission plate 23, which is rotatably connected to the first transmission shaft 22, to rotate. This causes the connecting frame 27, which is fixedly connected to the second transmission shaft 24, to move, causing the connecting spring 28, which is fixedly connected to the connecting frame 27, to be stretched, generating elastic potential energy. When the yarn is being wound up, it drives the rotating drum 31 to rotate around the axis of the rotating shaft 30, allowing the pressure sensor 32 on the rotating drum 31 to monitor the tension of the yarn in real time, thereby adjusting the tension of the yarn and preventing yarn breakage.

[0083] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
