Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides an embodiment: a bobbin clamping device for a bobbin rewinding machine, comprising a supporting base 3, a positioning component 1 is symmetrically fixedly installed on the top of the supporting base 3, a wire bobbin 2 is slidably sleeved on the top of the positioning component 1, the positioning component 1 comprises a first positioning device 4 and a second positioning device 5, the first positioning device 4 is fixedly installed on the top of the side end of the second positioning device 5, the first positioning device 4 comprises a positioning turn handle 6, a clamping plate 7, a threaded rod 8 and a threaded barrel 9, the clamping plate 7 is rotatably installed on the outer ring of the positioning turn handle 6, the positioning turn handle 6 is fixedly installed on the top center of the threaded rod 8, and the threaded rod 8 is threadedly inserted in the top center of the threaded barrel 9.

[0021] The second positioning device 5 includes a positioning base plate 10, a supporting sleeve 11, a limiting spring 12, a guide handle 13, a T-shaped sliding key 14 and a plastic block 15. The limiting spring 12 is fixedly installed inside the supporting sleeve 11, the T-shaped sliding key 14 slides through the supporting sleeve 11 and is fixedly connected to one end of the limiting spring 12, the guide handle 13 is fixedly installed at the end of the T-shaped sliding key 14 away from the limiting spring 12, the plastic block 15 is fixedly installed at the top of the side end of the guide handle 13 close to the limiting spring 12, and the positioning base plate 10 is fixedly installed at the bottom end of the plastic block 15. By setting the positioning base plate 10, the bobbin 2 can be prevented from falling.

[0022] The support sleeve 11 is fixedly mounted on both ends of the top of the support base 3, and the threaded tube 9 is fixedly mounted on the side end of the plastic block 15 away from the limiting spring 12, so as to support the clamping plate 7 to perform the limiting work.

[0023] A plastic gasket is fixedly mounted on the bottom end of the clamping plate 7 to prevent the clamping plate 7 from crushing the bobbin 2 .

[0024] The positioning components 1 are respectively arranged at two ends of the top of the support base 3 to enhance the limiting strength of the wire barrel 2 .

[0025] The interior of the support sleeve 11 is hollow, and one end of the T-shaped sliding key 14 close to the limiting spring 12 is in contact with the inner wall of the support sleeve 11 , which ensures that the T-shaped sliding key 14 moves in a straight line.

[0026] Working principle: When in use, first install the support base 3 on the bearing of the rewinding machine so that the support base 3 can rotate freely, then rotate the card plate 7 until the card plate 7 is rotated to face away from the plastic block 15, and at the same time, the guide handle 13 can be pulled toward the end away from the limiting spring 12, so as to drive the two plastic blocks 15 to approach each other, then slide the wire spool 2 onto the plastic block 15, and then release the guide handle 13. At this time, the elasticity of the limiting spring 12 will drive the guide handle 13 and the plastic block 15 to quickly reset until the plastic block 15 is close to one end of the limiting spring 12. The surface of the thread barrel 2 is in contact with the inner wall of the thread barrel 2, and the positioning base plate 10 is located at the bottom end of the plastic block 15, so that the thread barrel 2 can be prevented from falling off the plastic block 15. At the same time, the plastic block 15 is in contact with the inner wall of the thread barrel 2, so that the thread barrel 2 can be temporarily fixed. When the guide handle 13 moves, the T-shaped sliding key 14 is slidably inserted into the center of one end of the supporting sleeve 11 close to the guide handle 13, so that the plastic block 15 can be ensured to move in a straight line, thereby improving the docking accuracy of the plastic block 15 and the inner wall of the thread barrel 2. Afterwards, when the plastic block 15 is in contact with the inner wall of the thread barrel 2, the card can be The plate 7 is rotated to be vertically aligned with the outer ring surface of the wire drum 2, and then the positioning handle 6 is screwed and rotated to allow the clamping plate 7 to move downward until the clamping plate 7 is in contact with the top of the wire drum 2, which can prevent the wire drum 2 from jumping upward when in use, and complete the work of limiting the positioning of the wire drum 2. When the device is in use, the positioning handle 6, clamping plate 7, threaded rod 8 and threaded barrel 9 on the two plastic blocks 15 are arranged to be staggered with each other, so that when the guide handle 13 is pulled toward the end away from the limiting spring 12, the clamping plates 7 and the clamping plates 7 are prevented from interfering with each other, so that the wire drum 2 can slide on the plastic block 15. The outer circle of the rubber block 15, and the clamping plate 7 can be flexibly rotated and adjusted on the positioning handle 6, so that when the bobbin 2 is displaced onto the plastic block 15, the clamping plate 7 and the bobbin 2 are prevented from interfering, thereby completing the positioning of the bobbin 2. Afterwards, when the bobbin 2 needs to be taken out, the positioning handle 6 can be screwed and rotated again until the clamping plate 7 is out of contact with the bobbin 2, and then the clamping plate 7 is rotated to be misaligned with the top end of the bobbin 2, and then the guide handle 13 is pulled toward the end away from the limiting spring 12, so that the plastic block 15 can be out of contact with the bobbin 2, and then the bobbin 2 is pulled upward to complete the removal of the bobbin 2.
