Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to a yarn bobbin fixing structure of a twisting machine. Background Art

[0002] A twisting machine is a textile machinery equipment that twists multiple strands of fine yarn into one strand. Its function is to process yarn or plied yarn products into linear products for use in weaving and knitting.

[0003] After retrieval, the prior art with the publication number CN206502907U discloses a yarn bobbin fixing structure of a twisting machine, which includes a base. A bobbin shaft is vertically installed upward on the base. A damping member is installed on the bobbin shaft, and the damping member is in contact connection with the inner wall of the yarn bobbin. In the natural state, the damping member fixes the yarn bobbin through friction for normal wire drawing. When suddenly acted upon by the pulling force of the wire, the yarn bobbin can rotate against the resistance exerted by the damping member, and this utility model uses the yarn bobbin fixing for normal yarn output. When being pulled, it can rotate to avoid breaking the yarn, thereby ensuring that the quality of the yarn is not affected.

[0004] However, although the yarn bobbin fixing structure of this utility model can ensure that the quality of the yarn is not affected, there is no limit structure provided at both sides of the yarn bobbin. When the yarn moves, it may lack a limit structure and cannot be effectively fixed tightly to the outer side of the yarn bobbin, and may fall off. Therefore, a yarn bobbin fixing structure of a twisting machine is proposed to solve the problems raised above. Content of the Utility Model

[0006] To achieve the above object, the utility model provides the following technical solution: A yarn bobbin fixing structure of a twisting machine includes two fixing plates. A connecting rod is fixedly connected between the two fixing plates. Two moving plates are slidably connected inside the fixing plates. One side of the two moving plates away from the fixing plates is respectively fixedly connected with an upper yarn bobbin and a lower yarn bobbin. Two limit structures are arranged on the outer sides of the upper yarn bobbin and the lower yarn bobbin;

[0007] The limit structure includes two upper limit plates sleeved on the outer side of the upper yarn bobbin, a threaded rod sleeved on one side of the upper limit plate, a lower limit plate threadedly connected to the lower outer wall of the threaded rod, a limit rod integrally connected to the side of the lower limit plate away from the threaded rod, and a rubber pad bonded to the opposite sides of the upper limit plate and the lower limit plate.

[0008] Furthermore, a spacing adjustment device is provided on one side of the connecting rod. The spacing adjustment device includes a fixed box fixedly connected to one side of the connecting rod, a rotating shaft sleeved at one end of the fixed box, a first bevel gear sleeved on the side of the rotating shaft close to the fixed box, a second bevel gear meshed and connected to the lower side of the first bevel gear, a second threaded rod sleeved on the inner wall of the second bevel gear, a threaded sleeve threadedly connected to the outside of the second threaded rod, and a limiting and assisting structure provided on the side surface of the threaded sleeve. The top of the threaded sleeve is fixedly connected to the inner wall surface of the upper yarn bobbin.

[0009] Furthermore, the limiting and assisting structure includes a connecting block fixedly connected to the side surface of the threaded sleeve, a spring fixedly connected to the side of the connecting block away from the threaded sleeve, a clamping block fixedly connected to the side of the spring away from the connecting block, and two vertical plates fixedly connected to the inside of the fixed box.

[0010] Furthermore, the two vertical plates are fixedly arranged on the side surface of the threaded sleeve in a symmetrical structure, and a plurality of grooves adapted to the clamping block are formed on the opposite sides of the two vertical plates.

[0011] Furthermore, a chute adapted to the moving plate is formed inside the fixed disk, and the outer wall of the moving plate is slidably connected in the chute.

[0012] Furthermore, the side of the moving plate away from the connecting rod is respectively vertically fixed inside the upper yarn bobbin and the lower yarn bobbin.

[0013] Furthermore, two telescopic support rods are fixedly connected to the outside of the left side of the connecting rod.

[0014] Furthermore, the ends of the two telescopic support rods away from the connecting rod are respectively vertically connected to the opposite surfaces of the upper yarn bobbin and the lower yarn bobbin.

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment 1:

[0027] Please refer to Figures 1 to 6 , a yarn bobbin fixing structure of a twisting machine in this embodiment includes two fixed disks 3. A connecting rod 5 is fixedly connected between the two fixed disks 3. Two moving plates 4 are slidably connected inside the fixed disks 3. One sides of the two moving plates 4 away from the fixed disks 3 are respectively fixedly connected with an upper yarn bobbin 1 and a lower yarn bobbin 2. Two limiting structures 7 are arranged outside the upper yarn bobbin 1 and the lower yarn bobbin 2. The limiting structure 7 includes two upper limiting plates 18 sleeved outside the upper yarn bobbin 1, a threaded rod 22 sleeved on one side of the upper limiting plate 18, a lower limiting plate 19 threadedly connected to the lower outer wall of the threaded rod 22, a limiting rod 20 integrally connected to the side of the lower limiting plate 19 away from the threaded rod 22, and a rubber pad 21 bonded to the opposite sides of the upper limiting plate 18 and the lower limiting plate 19.

[0028] Among them, a spacing adjustment device 6 is provided on one side of the connecting rod 5. The spacing adjustment device 6 includes a fixed box 8 fixedly connected to one side of the connecting rod 5, a rotating shaft 17 sleeved on one end of the fixed box 8, a first bevel gear 9 sleeved on the side of the rotating shaft 17 close to the fixed box 8, a second bevel gear 10 meshed and connected to the lower side of the first bevel gear 9, a second threaded rod 11 sleeved on the inner wall of the second bevel gear 10, a threaded sleeve 12 threadedly connected to the outer side of the second threaded rod 11, and a limit and auxiliary structure provided on the side surface of the threaded sleeve 12. The top of the threaded sleeve 12 is fixedly connected to the inner wall surface of the upper yarn bobbin 1. The limit and auxiliary structure includes a connecting block 13 fixedly connected to the side surface of the threaded sleeve 12, a spring 14 fixedly connected to the side of the connecting block 13 away from the threaded sleeve 12, a clamping block 15 fixedly connected to the side of the spring 14 away from the connecting block 13, and two vertical plates 16 fixedly connected to the inside of the fixed box 8. The two vertical plates 16 are symmetrically fixed to the side surface of the threaded sleeve 12. A plurality of grooves adapted to the clamping block 15 are provided on the opposite sides of the two vertical plates 16. A sliding groove adapted to the moving plate 4 is provided inside the fixed disk 3. The outer wall of the moving plate 4 is slidably connected in the sliding groove. The side of the moving plate 4 away from the connecting rod 5 is vertically fixed inside the upper yarn bobbin 1 and the lower yarn bobbin 2 respectively.

[0029] Embodiment 2:

[0030] Please refer to Figure 1 , on the basis of Embodiment 1, two telescopic support rods are fixedly connected to the outside of the left side of the connecting rod 5. The ends of the two telescopic support rods away from the connecting rod 5 are respectively vertically connected to the opposite surfaces of the upper yarn bobbin 1 and the lower yarn bobbin 2.

[0031] By adopting the above technical solution, when the spacing adjustment device 6 adjusts the spacing between the upper yarn bobbin 1 and the lower yarn bobbin 2, the telescopic support rods can effectively cooperate with the spacing adjustment device 6 to support the other ends of the upper yarn bobbin 1 and the lower yarn bobbin 2.

[0032] The working principle of the above embodiment is as follows:

[0033] The yarn is wound around the outer sides of the upper yarn bobbin 1 and the lower yarn bobbin 2. Rotating the rotating shaft 17 meshes the first bevel gear 9 with the second bevel gear 10, driving the threaded sleeve 12 on the outer side of the second threaded rod 11, and pushing the upper yarn bobbin 1 to separate from the upper side of the lower yarn bobbin 2, enabling better control of the arrangement and tightness of the yarn, improving the overall quality of the yarn. During the movement of the threaded sleeve 12, the connecting block 13 on the side elastically changes the position of the clamping block 15 through the spring 14 to move in the grooves with different heights opened on the vertical plate 16, playing a limiting role to prevent the yarn from falling off the outer sides of the upper yarn bobbin 1 and the lower yarn bobbin 2 when the yarn rotates. It is also necessary to take out two groups of upper limit plates 18 and lower limit plates 19, respectively sleeve them from the outer sides of the upper yarn bobbin 1 and the lower yarn bobbin 2 and abut against both ends of the yarn on both sides. Rotating the threaded rod 22 on one side of the upper limit plate 18 drives the upper limit plate 18 to approach the lower limit plate 19. The limit rod 20 of the other lower limit plate 19 is inserted into the upper limit plate 18 until the rubber pads 21 inside the upper limit plate 18 and the lower limit plate 19 are attached to the surfaces of the upper yarn bobbin 1 and the lower yarn bobbin 2, then the rotation can be stopped to achieve the limiting effect on the sides of the yarn.
