Description

Technical Field

[0001] The utility model relates to the technical field of yarn bobbin holders, in particular to a yarn bobbin holder with auxiliary limiting function. Background Technique

[0002] The bobbin holder is a component of the warping machine, mainly used for installing the bobbin cores around which yarns are wound. Among them, the warping machine includes a yarn feeding structure, a yarn dividing structure, a tensioning structure, a yarn guiding structure and a yarn collecting structure, and the bobbin holder is an important part of the yarn feeding structure. During operation, under the traction of the yarn collecting mechanism of the warping machine, the yarn bobbin rotates to unwind the yarn. After the yarn passes through the yarn dividing structure, the tensioning structure and the yarn guiding structure, it is finally collected by the yarn collecting structure, so as to realize the warping process of the yarn.

[0003] At present, the existing bobbin holders generally consist of a frame body and bobbin cores for supporting the yarn bobbins. When in use, the yarn bobbins are sleeved on the bobbin cores. When the yarn bobbins are normally winding yarn, the yarn bobbins rotate to unwind the yarn. Since the sizes of the bobbin cores and the yarn bobbins are not completely matched, during the rotation of the yarn bobbins, the yarn bobbins are prone to jumping, resulting in poor stability during the rotation of the yarn bobbins and prone to falling off. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a yarn bobbin holder with auxiliary limiting function to solve the technical problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A yarn bobbin holder with auxiliary limiting function, including a frame body. A plurality of connecting frames are arranged on one side of the frame body. One side of each of the plurality of connecting frames is provided with a limiting mechanism. The limiting mechanism includes a first guiding groove, a second guiding groove and a rotating motor. A fixing frame is arranged on the side of the connecting frame away from the frame body. A rotating shaft is rotatably connected to the inside of the fixing frame through a bearing. A rotating plate welded to the rotating shaft is arranged inside the fixing frame. A limiting column penetrates through the inside of the fixing frame and the rotating plate. A limiting plate is arranged on the side of the limiting column away from the fixing frame.

[0006] Preferably, a rotating motor connected to the rotating shaft through a coupling is installed on the side of the fixing frame close to the frame body. Six limiting columns are arranged at equal angles with the fixing frame as the center, and the six limiting columns form a bobbin core.

[0007] Preferably, first guiding grooves are opened at both ends of the fixing frame, and a second guiding groove is opened inside the rotating plate. The limiting column forms a sliding structure with the fixing frame and the rotating plate through the first guiding groove and the second guiding groove respectively.

[0008] Preferably, a ball groove is formed on the outer surface of the limit post, and a ball is rotatably connected inside the ball groove.

[0009] Preferably, a locking mechanism is arranged on one side of the fixed frame, and the locking mechanism is composed of a gear, a rack, an electric push rod and a mounting plate.

[0010] Preferably, the gear is sleeved on the outer surface of the rotating shaft, the mounting plate is welded to one end of the fixed frame, the electric push rod is installed at one end of the mounting plate close to the gear, and a rack meshed with the gear is arranged at one end of the electric push rod.

[0011] Preferably, symmetrically arranged guide plates are welded to one side of the rack, a vertical plate is welded to one end of the fixed frame, and the rack and the fixed frame form a sliding structure through the guide plates and the vertical plate.

[0012] In summary, the main beneficial effects of the present utility model are as follows:

[0013] When the existing creel is in use, since the sizes of the core and the yarn bobbin are not completely adapted, the stability of the yarn bobbin during rotation is poor, and it is easy to fall off. By providing a limiting mechanism and a limiting plate, when the rotating motor works, the output end of the rotating motor drives the rotating shaft and the rotating plate to rotate. Since the limit posts are slidably connected to the rotating plate and the fixed frame through the second guide groove and the first guide groove respectively, multiple limit posts move away from or close to each other simultaneously, so as to adjust the size of the core to make it adapted to the yarn bobbin, prevent the supported yarn bobbin from jumping during rotation, so as to increase the stability, and at the same time cooperate with the limiting plate to realize the auxiliary limitation of the yarn bobbin to prevent the yarn bobbin from falling off;

[0014] By providing a locking mechanism, since the rack and the fixed frame are slidably connected through the guide plates and the vertical plate, when the electric push rod works and extends, the rack moves towards the gear and meshes with the gear, so as to position the rotating shaft and prevent the adjusted limit post from loosening, so as to increase the stability during use.

[0021] 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. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0022] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model.

[0023] A yarn bobbin rack capable of assisting in limiting, as Figure 1 , Figure 3 and Figure 4 shown, includes a frame body 1. A plurality of connecting frames 7 are provided on one side of the frame body 1. Six of the limiting columns 206 form a bobbin core, and a yarn bobbin is sleeved on the outer surface of the bobbin core, and at the same time, the bobbin core is adapted to the yarn bobbin. At this time, under the traction of the winding mechanism of the warping machine, the yarn bobbin can be rotated to unwind the yarn.

[0024] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4It can be seen that a limiting mechanism 2 is provided on one side of each of the plurality of connecting frames 7. The limiting mechanism 2 includes a first guiding groove 202, a second guiding groove 204 and a rotating motor 207. A fixing frame 201 is provided on the side of the connecting frame 7 away from the frame body 1. A rotating shaft 205 is rotatably connected to the inside of the fixing frame 201 through a bearing. A rotating plate 203 welded to the rotating shaft 205 is provided on the inner side of the fixing frame 201. A limiting column 206 penetrates through the inner sides of the fixing frame 201 and the rotating plate 203. A limiting plate 3 is provided on the side of the limiting column 206 away from the fixing frame 201. A rotating motor 207 connected to the rotating shaft 205 through a coupling is installed on the side of the fixing frame 201 close to the frame body 1. Six limiting columns 206 are arranged at equal angles with the fixing frame 201 as the center. First guiding grooves 202 are formed at both ends of the fixing frame 201. A second guiding groove 204 is formed inside the rotating plate 203. The limiting column 206 forms a sliding structure with the fixing frame 201 and the rotating plate 203 through the first guiding groove 202 and the second guiding groove 204 respectively. The second guiding groove 204 is arranged in an arc shape and is inclined;

[0025] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 It can be seen that when the rotating motor 207 works, the output end of the rotating motor 207 drives the rotating shaft 205 and the rotating plate 203 to rotate. Since the limiting column 206 is slidably connected to the rotating plate 203 and the fixing frame 201 through the second guiding groove 204 and the first guiding groove 202 respectively, the plurality of limiting columns 206 move away from or close to each other simultaneously, so as to realize the adjustment of the core size, make it adapt to the yarn bobbin, prevent the supported yarn bobbin from jumping during rotation, increase the stability, and at the same time cooperate with the limiting plate 3 to realize the auxiliary limitation of the yarn bobbin to prevent the yarn bobbin from falling off.

[0026] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 It can be seen that a locking mechanism 4 is provided on one side of the fixing frame 201. The locking mechanism 4 is composed of a gear 401, a toothed plate 402, an electric push rod 403 and a mounting plate 404. The gear 401 is sleeved on the outer surface of the rotating shaft 205. The mounting plate 404 is welded to one end of the fixing frame 201. The electric push rod 403 is installed at one end of the mounting plate 404 close to the gear 401. A toothed plate 402 meshed with the gear 401 is provided at one end of the electric push rod 403;

[0027] Refer to Figure 2 , Figure 3 and Figure 5It can be seen that since the toothed plate 402 and the fixed frame 201 are slidably connected through the guide plate 5 and the vertical plate 6, during the operation and extension of the electric push rod 403, the toothed plate 402 moves towards the gear 401 and meshes with the gear 401, thereby realizing the positioning of the rotating shaft 205, preventing the adjusted limit post 206 from loosening, and increasing the stability during use.

[0028] Refer to Figure 5 It can be seen that symmetrically arranged guide plates 5 are welded to one side of the toothed plate 402, and a vertical plate 6 is welded to one end of the fixed frame 201. The toothed plate 402 and the fixed frame 201 form a sliding structure through the guide plate 5 and the vertical plate 6, which can play a role in supporting and limiting, and can increase the stability of the toothed plate 402 during the sliding process.

[0029] Refer to Figure 3 and Figure 4 It can be seen that a ball groove 9 is formed on the outer surface of the limit post 206, and balls 8 are rotatably connected inside the ball groove 9, which can reduce the friction between the yarn bobbin and the limit post 206 and make the rotation of the yarn bobbin smooth.

[0030] The working principle of the present utility model is as follows: when using the yarn bobbin holder capable of assisting in limiting, the yarn bobbin is sleeved on the outer surfaces of a plurality of limit posts 206. At the same time, the rotation motor 207 is started, so that the output end of the rotation motor 207 drives the rotating shaft 205 and the rotating plate 203 to rotate. Then, a plurality of limit posts 206 approach the yarn bobbin simultaneously under the action of the first guide groove 202 and the second guide groove 204, so that the bobbin core is adapted to the yarn bobbin. At this time, under the traction of the winding mechanism of the warping machine, the yarn bobbin rotates to unwind the yarn. During this process, it is possible to prevent the yarn bobbin supported by the bobbin core from jumping during rotation, so as to increase the stability. At the same time, the limit plate 3 is cooperated to realize the auxiliary limit of the yarn bobbin to prevent the yarn bobbin from falling off.
