[0002] In the textile industry, yarn bobbins are widely used as textile accessories, for example, in cotton spinning, silk spinning, synthetic fiber spinning, and blended spinning. When in use, one end is inserted into the shaft of the spinning frame. The shaft rotates at high speed, driving the spindle to rotate, spinning the short fibers into yarn, and then winding the spun yarn onto the yarn bobbin. After the yarn is wound on the bobbin, the bobbin needs to be removed. However, in the existing technology, manual removal is usually used. Each time the machine is removed, it is necessary to temporarily stop working or partially stop the operation of the machine, which leads to low work efficiency and insufficient production capacity to a certain extent. In addition, workers need to stay next to the machine to monitor and remove the bobbin at any time.

DETAILED DESCRIPTION

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0026] The utility model provides a line grabbing and turning device, combined with Figure 1-4 As shown, it includes a lifting and rotating structure 10, the lifting and rotating structure 10 is connected to a support plate 11, a plurality of clamping components 12 are provided on the support plate 11, and the plurality of clamping components 12 are connected to a grabbing drive component 13, a grabbing port 14 is provided in the clamping component 12, and the grabbing drive component 13 can drive the grabbing port 14 in the clamping component 12 to open or tighten.

[0027] In this embodiment, the lifting and rotating structure 10 works to make the support plate 11 move upward with the clamping assembly 12 and the grabbing drive assembly 13. When it moves to the position for grabbing the material, the material extends into the grabbing mouth 14. Then, the grabbing drive assembly 13 is used to make the clamping assembly 12 lock the grabbing mouth to grab the material. Then, the lifting and rotating structure 10 drives the support plate 11 to move back to its position and then rotates to make the clamping assembly 12 rotate. Then, the grabbing drive assembly 13 is used to make the clamping assembly 12 open the grabbing mouth to remove the material, thereby realizing automated material unloading operations, replacing manual methods and improving work efficiency.

[0028] The clamping assembly 12 includes two grabbing grippers 15 , which extend out of the support plate 11 . The grabbing opening 14 is located between the two grabbing grippers 15 , and at least one of the grabbing grippers 15 is connected to the grabbing drive assembly 13 .

[0029] In this embodiment, the material is grasped and unloaded by the two grasping grippers 15 moving closer to and farther from each other, and the grasping drive assembly 13 is used to move one of the grasping grippers 15 or both of the grasping grippers 15 together.

[0030] A synchronous linkage structure is provided between the two corresponding grabbing grippers 15 , and the synchronous linkage structure enables the two grabbing grippers 15 to move closer to or away from each other.

[0031] In this embodiment, the two grabbing grippers 15 are moved synchronously by a synchronous linkage structure, thereby preventing the entire workflow from being stalled due to inconsistent movements of the grabbing grippers 15 and failure to grip materials, and further eliminating the need for workers to participate in the operation.

[0032] The synchronous linkage structure includes a rotating wheel 16 connected to the grabbing gripper 15, and the rotating wheel 16 is rotatably set on the support plate 11. At least one of the rotating wheels 16 is connected to the grabbing drive assembly 13. The rotating wheel 16 is also provided with an engaging ring gear 17, and the engaging ring gears 17 of the two corresponding rotating wheels 16 are engaged and connected.

[0033] In this embodiment, the grabbing grippers 15 are rotatably connected to the support plate 11 via a rotating wheel 16. When the grabbing drive assembly 13 drives one of the rotating wheels 16 to rotate, the two rotating wheels 16 rotate synchronously through the meshing ring gear 17, so that the two grabbing grippers 15 approach each other synchronously to clamp the material.

[0034] The grabbing drive assembly 13 includes a drive plate 18 that is slidingly connected to the support plate 11, the drive plate 18 is connected to the linear drive 31, the turntable 16 is connected to the drive plate 18 through a connecting rotating rod 19, and the drive plate 18 is provided with a plurality of push blocks 20 that correspond one to one with the connecting rotating rod 19. The push blocks 20 are abutted against the end of the connecting rotating rod 19 away from the connecting rotating rod 19, and the connecting rotating rod 19 is also connected to a rebound device.

[0035] In this embodiment, when the grabbing drive assembly 13 is working, the linear drive 31 pushes the drive plate 18 to move laterally, so that the push block 20 pushes the connecting rotating rod 19, and then pushes the rotating wheel 16 to rotate to realize the clamping work. During the unloading process, the linear drive 31 works to make the drive plate 18 move back. Under the elastic force of the rebound device, the connecting rotating rod 19 is prompted to rotate to the initial position when the material is not clamped and resist against the push block 20, so that the grabbing clamps 15 move away from each other to complete the unloading work.

[0036] The rebound device and the push block 20 are located on the same side of the connecting rod 19 . The rebound device includes a rebound spring 21 . Both ends of the rebound spring 21 are connected to the support plate 11 and the connecting rod 19 , respectively.

[0037] In this embodiment, when the connecting rod 19 rotates to clamp the material, the rebound spring 21 is stretched, so that the rebound spring 21 generates a larger elastic force. After the driving plate 18 moves back, the rebound spring 21 pulls the connecting rod 19 to move back.

[0038] The driving plate 18 is provided with a plurality of limiting slots 22 , and a limiting post 23 fixed on the support plate 11 is slidably connected in each limiting slot 22 .

[0039] In this embodiment, the moving distance of the driving plate 18 is limited by the limit column 23. When the driving plate 18 moves to the extreme position, the two grabbing clamps 15 can just grab the material, preventing the driving plate 18 from moving too far and causing the two grabbing clamps 15 to be too close to each other and thus damaging the material.

[0040] The lifting and rotating structure 10 includes a lifting plate 24, at least one support rod 25 is provided in the lifting plate 24, a lifting slot 26 is provided in the support rod 25, a lifting rod 27 is slidably connected in the lifting slot 26, and the lifting rod 27 is fixedly connected to the support plate 11. At least one lifting driver 32 is provided on the lifting plate 24, and the output shaft of the lifting driver 32 is fixedly connected to the support plate 11 through a connecting block 33.

[0041] In this embodiment, the lifting and lowering of the support plate 11 is achieved through the operation of the lifting driver 32 and the sliding connection between the lifting rod 27 and the lifting slot 26 .

[0042] The bottom of the jacking plate 24 is connected to a rotating shaft 28 , and the rotating shaft 28 is rotatably disposed in a support seat 29 . A driving connecting shaft 30 is disposed at one end of the rotating shaft 28 .

[0043] In this embodiment, the driving connecting shaft 30 is connected to an external rotational power source to drive the entire device to rotate.

[0044] The inner walls on both sides of the grabbing opening 14 are curved and are provided on the grabbing grippers 15 .

[0045] In this embodiment, when grabbing materials, the grabbing opening 14 forms a circular cavity shape, and the inner wall of the grabbing opening 14 can be covered with a rubber cushion layer with deformation ability, which has the function of firmly grabbing materials and preventing materials from being clamped and damaged.

[0046] The working principle of the present invention is as follows: the lifting drive 32 works to make the lifting rod 27 move the support plate 11 upward, and the clamping assembly 12 and the grabbing drive assembly 13 move synchronously, so that the material is just located in the grabbing port 14, and then the linear drive 31 works to push the driving plate 18 to move horizontally, so that the pushing block 20 pushes the connecting rotating rod 19, and then drives the rotating wheel 16 to rotate, so that the two grabbing clamps 15 are close to each other to achieve the clamping work. At the same time, the rebound spring 21 is stretched to generate a pulling force on the connecting rotating rod 19, and the lifting drive 32 moves back to make the support plate 11 move back, and then drives the connecting shaft 30 to connect with the external rotating power source to drive the entire device to rotate. At this time, it is in the unloading position, and the linear drive 31 works to move the driving plate 18 back, and the rebound spring 21 will pull the connecting rotating rod 19 back, thereby prompting the connecting rotating rod 19 to rotate to the initial position when the material is not clamped and resist the pushing block 20, and the grabbing clamps 15 move away from each other to complete the unloading work.
