Description

Technical Field

[0001] The utility model relates to the technical field of silk thread processing, and particularly relates to a silk thread warp knitting device. Background Art

[0002] Silk thread warp knitting refers to a textile process in which yarns or woven fabrics are formed into various knitting structures and patterns through techniques such as knitting, crochet, and stringing. It is an important technology and handicraft in the textile industry and is widely used in fields such as clothing, furniture supplies, and industrial products.

[0003] During the processing of the silk thread warp knitting device, the roller shafts of the device can control the tension of the silk thread by adjusting the spacing. However, this method can only be operated and controlled outside the silk thread processing process. During the processing, the silk thread may change in tension due to factors such as static electricity. The existing silk thread warp knitting devices cannot automatically adapt to the tension of the silk thread for adjustment, which affects the knitting effect of the silk thread and is very inconvenient. Summary of the Utility Model

[0004] Based on the above description, the utility model provides a silk thread warp knitting device to solve the problem that the existing silk thread warp knitting devices cannot automatically adapt to the tension of the silk thread for adjustment.

[0005] The technical solution for the utility model to solve the above technical problems is as follows: A silk thread warp knitting device includes a base and first roller shaft members installed at both ends of the surface of the base. A connecting member is arranged outside the base, and a second roller shaft member that rotates and moves is arranged inside the connecting member. A torsion spring is installed between the second roller shaft member and the connecting member. The second roller shaft member automatically adjusts the unfolding angle through the transmission tension of the surface silk thread in cooperation with the torsion spring. A bolt is arranged inside the connecting member, and a third roller shaft member that moves vertically along the inside of the connecting member is installed outside the bolt.

[0006] Based on the above technical solution, the utility model can be further improved as follows.

[0007] Further, the connecting member is composed of a mounting seat. The mounting seat is installed in the center of the surface of the base and is parallel to the two first roller shaft members. A notch is opened at the center of the end of the mounting seat away from the base.

[0008] Further, sliding grooves are opened on both sides of the inner wall of the notch away from each other. An activity groove is opened on one side of the surface of the mounting seat, and the side of the inner wall of the activity groove close to the base is inclined outward.

[0009] Furthermore, an axle is installed between the two ends of the inner wall of the movable groove, the second roller shaft is installed on the outside of the axle, the torsion spring is inserted on the outside of the axle, and installed between the side of the inner wall of the second roller shaft close to the base and the inner wall of the movable groove.

[0010] Furthermore, the bolt is installed at the center of the inner wall of the slot close to the base, and the outer end of the bolt close to the base is provided with a rod body distributed in a ring shape with equal distances and extending to the outside of the mounting seat.

[0011] Furthermore, the third roller component is installed on the inner side of the slot, a threaded hole is provided on the side of the third roller component close to the base, and the third roller component is installed on the outer side of the bolt through the threaded hole, and sliders slidably connected to the slide groove are provided at both ends of the third roller component.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0013] The utility model uses a shaft rod and a second roller member, in cooperation with a torsion spring, and the torsion spring causes the second roller member to expand and unfold toward the base in a natural state through torsion force. When the silk thread passes around the second roller member, the second roller member can, under the influence of the silk thread tensioning force, transmit the external force generated by different tensioning forces to the torsion spring, so that the torsion spring and the second roller member are subjected to forces to unfold at different angles. When the silk thread is relatively loose, the unfolding angle of the torsion spring and the second roller member is large, which is adapted to the tensioning of the silk thread. When the silk thread is tight, the torsion spring and the second roller member are subjected to force, resulting in a small unfolding angle that is adapted to the tensioning of the silk thread. During the process, the second roller member can automatically adjust the unfolding angle through the force of the torsion spring to adapt to the tensioning of the silk thread, thereby ensuring the warp knitting effect of the silk thread and reducing the influence of factors such as static electricity on the change of the tension of the silk thread.

[0020] To facilitate the understanding of the present application, the present application will be described more comprehensively below with reference to the relevant drawings. Embodiments of the present application are given in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the description of the present application in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0022] Please refer to Figures 1-4 , a silk warp knitting device of the present utility model, comprising a base 1 and first roller shaft members 2 installed at both ends of the surface of the base 1. A connecting member is provided on the outer side of the base 1, and a rotatably movable second roller shaft member 5 is provided on the inner side of the connecting member. A torsion spring 6 is installed between the second roller shaft member 5 and the connecting member. The second roller shaft member 5 automatically adjusts the unfolding angle through the transmission tension of the surface silk in cooperation with the torsion spring 6. A bolt 7 is provided on the inner side of the connecting member, and a third roller shaft member 8 that moves vertically along the inner side of the connecting member is installed on the outer side of the bolt 7.

[0023] Please refer to Figure 3 , the connecting member is composed of a mounting seat 3. The mounting seat 3 is installed in the center of the surface of the base 1 and is parallel to the two first roller shaft members 2. A notch 32 is opened at the center of the end of the mounting seat 3 away from the base 1. Slide grooves 33 are opened on both sides of the inner wall of the notch 32 away from each other. A movable groove 31 is opened on one side of the surface of the mounting seat 3. The side of the inner wall of the movable groove 31 close to the base 1 is inclined outward. The inclined setting at one end of the movable groove 31 can increase the rotation angle of the second roller shaft member 5 and facilitate the second roller shaft member 5 to cooperate with the loose silk for tension adjustment.

[0024] Please refer to Figure 2, a shaft rod 4 is installed between the two ends of the inner wall of the movable slot 31. The second roller shaft member 5 is installed outside the shaft rod 4. The torsion spring 6 is inserted outside the shaft rod 4 and installed between the inner wall of the second roller shaft member 5 close to the base 1 and the inner wall of the movable slot 31. In the natural state, the torsion spring 6 will cause the second roller shaft member 5 to unfold towards the base 1. When the silk thread bypasses the second roller shaft member 5 from the first roller shaft member 2, under the action of the tension force, the silk thread will pull the second roller shaft member 5 to rotate outside the shaft rod 4, causing the torsion spring 6 to be stressed. The second roller shaft member 5 and the torsion spring 6 move towards the mounting seat 3, and the torsion spring 6 is in a compressed state. The generated resilience can make the second roller shaft member 5 react on the silk thread, ensuring that the silk thread is in a taut state. When the silk thread is affected by static electricity and the tension changes and becomes slack, the resilience of the torsion spring 6 will push the second roller shaft member 5 to continue to rotate towards the base 1, stretching the silk thread so that it still remains in a taut state. After the silk thread is taut to the extreme, the resilience of the torsion spring 6 cannot act on the second roller shaft member 5 to continue stretching the silk thread, and the second roller shaft member 5 remains fixed for the silk thread to be transmitted. During the process, the transmission angle between the second roller shaft member 5 and the silk thread is related to the force received by the torsion spring 6. The torsion spring 6 can automatically adjust the angle of the second roller shaft member 5 under the influence of the tension force of the silk thread, so as to adapt to the transmission tension of the silk thread and ensure the warp knitting effect of the silk thread.

[0025] Please refer to Figure 4 , a bolt 7 is installed at the center of the inner wall of the notch 32 close to one side of the base 1. One end of the bolt 7 close to the base 1 is provided with rod bodies arranged at equal intervals in a ring shape and extending to the outside of the mounting seat 3. The third roller shaft member 8 is installed inside the notch 32. A threaded hole 81 is opened on one side of the third roller shaft member 8 close to the base 1, and the third roller shaft member 8 is installed outside the bolt 7 through the threaded hole 81. Sliders 9 are arranged at both ends of the third roller shaft member 8 and are slidably connected in the chute 33. The connection between the slider 9 outside the third roller shaft member 8 and the chute 33 limits the movement state and direction of the third roller shaft member 8. The third roller shaft member 8 can only move vertically inside the notch 32. Cooperating with the bolt 7 connected to the third roller shaft member 8, when the bolt 7 is rotated, affected by the threaded connection between the threaded hole 81 and the bolt 7, the third roller shaft member 8 can move vertically up and down along the notch 32 under the influence of the rotation direction of the bolt 7, adjusting the distance from the second roller shaft member 5, and can adjust the tension of the silk thread before warp knitting.
