DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0024] See also Figure 1-Figure 5 , a technical solution provided by the utility model:

[0025] A wire drum limiting device for electromagnetic wire production comprises a fixed plate 1, a rotating shaft 2 is rotatably mounted on the fixed plate 1, the rotating shaft 2 is used to sleeve the wire drum, and a fixing mechanism 3 is arranged on the rotating shaft 2 for fixing the wire drum on the rotating shaft 2. A driving motor 4 is fixedly mounted on the fixed plate 1, and the output end of the driving motor 4 is fixedly connected to one end of the rotating shaft 2 for driving the rotating shaft 2 to rotate.

[0026] The traditional method is to lock the wire drum on the rotating shaft 2 by external fasteners, which is laborious and inefficient. To solve this problem, the fixing mechanism 3 in this embodiment includes a plurality of guide rods 31, which are arranged in an equiangular radial shape with the axis of the rotating shaft 2 as the center. One end of the guide rod 31 is fixedly connected to the outer circumference of the rotating shaft 2, and a sliding plate 32 is slidably connected to the surface of the guide rod 31. The sliding plate 32 can slide along the diameter direction of the rotating shaft 2, and a folding plate 33 is fixedly connected to the end of the sliding plate 32 away from the rotating shaft 2. The plurality of folding plates 33 are arranged in an equiangular radial shape, which can buckle the wire drum from multiple angles. The inner wall of the folding plate 33 is provided with an inclined surface, which facilitates the outer edge of the wire drum to enter between the folding plate 33 and the sliding plate 32. The inclined surface is covered with a flexible material to increase the friction between the inner wall of the folding plate 33 and the surface of the wire drum, so that the contact between the two is closer, while preventing the rigid contact from damaging the surface of the wire drum.

[0027] Furthermore, the fixing mechanism 3 further comprises a rotating sleeve 35, which is rotatably sleeved on the rotating shaft 2, and a plurality of inclined grooves 351 are provided on the rotating sleeve 35, and the plurality of inclined grooves 351 are arranged in an equiangular radial shape with the axis of the rotating sleeve 35 as the center, and the number of the inclined grooves 351 is the same as the number of the sliding plates 32. A transmission rod 34 is movably connected to the inner wall of each inclined groove 351, and each transmission rod 34 is fixedly connected to a different sliding plate 32. The transmission direction of the motion can be changed through the inclined grooves 351. When the rotating sleeve 35 rotates relative to the rotating shaft 2, since the transmission rod 34 is fixed on the sliding plate 32, and the sliding plate 32 can only move in a direction perpendicular to the rotating shaft 2 due to the limiting effect of the guide rod 31, the rotating sleeve 35 can simultaneously drive the plurality of transmission rods 34 to approach the rotating shaft 2 through the inclined grooves 351, and then drive the plurality of folding plates 33 to lock the wire coil through the plurality of sliding plates 32.

[0028] In this embodiment, a locking assembly 36 is provided between the rotating sleeve 35 and the rotating shaft 2 to limit the relative rotation between the rotating sleeve 35 and the rotating shaft 2, thereby preventing the transmission rod 34 from moving randomly and improving the stability of the folding plate 33.

[0029] Specifically, the locking assembly 36 includes a connecting ring 361, which is fixedly sleeved on the rotating shaft 2. The outer surface of the connecting ring 361 protrudes from the rotating shaft 2. A groove for the connecting ring 361 to rotate is provided on the inner wall of the rotating sleeve 35. The surface of the connecting ring 361 fits with the groove inside the rotating sleeve 35, which can limit the relative movement between the rotating sleeve 35 and the rotating shaft 2 and prevent the rotating sleeve 35 from falling off the rotating shaft 2. A tooth groove 3611 is provided on the outer circumference of the connecting ring 361, and a tooth block 362 is inserted in the tooth groove 3611. The tooth groove 3611 cooperates with the tooth block 362 to limit the relative rotation between the rotating sleeve 35 and the rotating shaft 2. When the tooth block 362 is separated from the tooth groove 3611, the rotating sleeve 35 can rotate relative to the rotating shaft 2, and the angle of the inclined groove 351 can be adjusted at this time.

[0030] Furthermore, one end of the tooth block 362 away from the connecting ring 361 is fixedly connected to a connecting rod 363, the surface of the connecting rod 363 is slidably connected to the inner wall of the rotating sleeve 35, one end of the connecting rod 363 passes through the rotating sleeve 35 and is fixedly connected to a handle 365, and the connecting rod 363 can be pulled by the handle 365, thereby making the tooth block 362 disengage from the tooth groove 3611. The surface of the tooth block 362 is slidably connected to the inner wall of the rotating sleeve 35, and one end of the tooth block 362 is elastically connected to the inner wall of the rotating sleeve 35 through a spring 364, and the tooth block 362 is pressed by the elastic force of the spring 364, so that the teeth on the tooth block 362 are embedded in the tooth groove 3611, thereby achieving a limiting effect on the rotating sleeve 35.

[0031] See also Figure 5The end of the handle 365 close to the rotating sleeve 35 is fixedly connected to the first magnetic block 367, and the end of the first magnetic block 367 away from the handle 365 is magnetically connected to the second magnetic block 366. The end of the second magnetic block 366 away from the first magnetic block 367 is fixedly connected to the outer surface of the rotating sleeve 35, and the handle 365 is adsorbed on the rotating sleeve 35 by magnetic force, thereby further improving the limiting effect of the tooth block 362 and preventing the tooth block 362 from detaching from the tooth groove 3611.

[0032] When the wire drum limiting device for electromagnetic wire production of the utility model is used, the wire drum is first set on the rotating shaft 2, so that one end of the wire drum is pressed against the sliding plate 32. Then the handle 365 is pulled outward, and the handle 365 drives the tooth block 362 to move through the connecting rod 363, so that the tooth block 362 is disengaged from the tooth groove 3611. Then the rotating sleeve 35 is driven to rotate on the surface of the rotating shaft 2 by the handle 365, and the rotating sleeve 35 drives the transmission rod 34 to move toward the rotating shaft 2 through the inclined groove 351, and the transmission rod 34 drives the folding plate 33 to move through the sliding plate 32, so that the folding plate 33 fastens the edge of the wire drum. Then the handle 365 is released, and the tooth block 362 will automatically reset under the elastic force of the spring 364, and the teeth on the tooth block 362 enter the tooth groove 3611 to lock the rotating sleeve 35, and at the same time, the first magnetic block 367 is adsorbed on the second magnetic block 366 to limit the handle 365, so that the rotating sleeve 35 remains stable. When the wire reel needs to be removed, the handle 365 only needs to be pulled outward and rotated in the opposite direction.
