[0028] like Figures 1 to 3 A spinning winding tube positioning device shown in the figure includes a transmission shaft 1, an airbag 2, a fixed chuck 3 and a movable chuck 4, one end of the transmission shaft 1 has an opening 11, the interior of the transmission shaft 1 has a hollow cavity connected to the opening 11, the transmission shaft 1 has an outer surface and an inner surface arranged opposite to each other in the thickness direction, and the transmission shaft 1 is provided with a through hole 12 penetrating the outer surface and the inner surface; the airbag 2 is arranged in the hollow cavity, the airbag 2 includes a first end and a second end extended and arranged along a first direction of the transmission shaft 1, the first end and the second end both extend to the edge of the transmission shaft 1, and the first direction is perpendicular to the thickness direction of the transmission shaft 1; the fixed chuck 3 is arranged on the transmission shaft 1; the movable chuck 4 is movably connected to the opening 11, and the movable chuck 4 is provided with a push rod 43 on a side facing the transmission shaft 1.

[0029] The utility model fills the airbag 2 inside the transmission shaft 1. When the movable chuck 4 is connected to the opening 11 of the transmission shaft 1, the push rod 43 squeezes the airbag 2 so that at least a portion of the airbag 2 is exposed from the through hole 12 to contact the inner wall of the wire winding drum, thereby overcoming the defect of looseness or shaking of the wire winding drum caused by the increase in the gap between the wire winding drum and the transmission shaft 1, thereby ensuring the stability of use and product quality.

[0030] In the above embodiment, the movable chuck 4 includes a connecting portion 41 and a limiting portion 42 connected to the connecting portion 41, and the limiting portion 42 protrudes from the surface of the connecting portion 41. Preferably, the opening 11 of the transmission shaft 1 is threadedly connected to the connecting portion 41 of the movable chuck 4. As an example, the opening 11 of the transmission shaft 1 is provided with an external thread, and the connecting portion 41 of the movable chuck 4 is provided with an internal thread adapted to the external thread. When the movable chuck 4 needs to be installed, it is only necessary to screw the movable chuck 4 onto the opening 11 of the transmission shaft 1. Similarly, when the movable chuck 4 needs to be disassembled, it is only necessary to unscrew the movable chuck 4 from the opening 11 of the transmission shaft 1. That is, the transmission shaft 1 and the movable chuck 4 can be quickly disassembled and assembled by only using the threaded connection between the two, thereby facilitating the disassembly and assembly of the wire winding drum.

[0031] Furthermore, a limiting groove 421 is provided on one side of the limiting portion 42 facing the connecting portion 41. When the movable chuck 4 is installed on the opening 11 of the transmission shaft 1, the edge of the wire winding drum sleeved on the transmission shaft 1 is embedded in the limiting groove 421 of the movable chuck 4, thereby fixing and limiting the wire winding drum and effectively reducing the problem of wire winding drum jumping.

[0032] Preferably, the limiting groove 421 of the above-mentioned embodiment can adopt a wedge-shaped limiting groove 421. On the one hand, the wedge-shaped limiting groove 421 can facilitate the edge of the wire winding drum to be better embedded into the limiting groove 421 of the movable chuck 4. On the other hand, the wedge-shaped limiting groove 421 that gradually narrows from the inlet can limit the edge of the wire winding drum well.

[0033] In the above embodiment, the push rod 43 is embedded in the connecting portion 41, one end of the push rod 43 is connected to the limiting portion 42, and the other end of the push rod 43 protrudes from the connecting portion 41, that is, the length of the push rod 43 is greater than the length of the connecting portion 41. When the movable chuck 4 is screwed onto the opening 11 of the transmission shaft 1, as the movable chuck 4 is tightened toward the transmission shaft 1, the push rod 43 squeezes the airbag 2 in the transmission shaft 1 so that at least a portion of the airbag 2 is exposed from the through hole 12 to contact the inner wall of the wire winding drum, so as to compensate for the problem of increased gap between the wire winding drum and the transmission shaft 1 due to wear, and can overcome the defect of looseness or shaking of the wire winding drum caused by the increased gap between the wire winding drum and the transmission shaft 1.

[0034] Furthermore, there are a plurality of through holes 12 , and the plurality of through holes 12 are evenly arranged on the circumferential surface of the transmission shaft 1 to increase the contact area between the extruded airbag 2 and the wire winding drum.

[0035] In the above embodiment, the transmission shaft 1 is provided with a transmission part 13 connected to the power source at one end away from the outlet 11, that is, the transmission part 13 is connected to the power source, and the power source drives the transmission shaft 1 to rotate. This embodiment can be driven by existing driving technology, and this embodiment will not be described in detail here.

[0036] In the above embodiments, the fixing chuck 3 can be fixedly disposed on the transmission shaft 1 by means of bolts and nuts. Preferably, the fixing chuck 3 can be fixedly disposed between the opening 11 of the transmission shaft 1 and the transmission portion 13 .

[0037] The utility model has a simple structure, can overcome the defect that the wire winding drum is loose or shaken due to the increase of the gap between the wire winding drum and the transmission shaft 1, and ensures the stability of use and product quality.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
