As shown in fig. 3 to 5, the center lines 3181 of the sector gears 318 of the two sets of reduction gear sets 313 extend in the same direction, so that only one sector gear 318 is meshed with the rack 32 at the same time, as shown in fig. 3 and 4, the sector gear 318 on the left is used for driving the rack 32 to move downwards, and the sector gear 318 on the right is used for driving the rack 32 to move upwards, so that the rack 32 reciprocates up and down to be close to or far from the unwinding rotary shaft 22. The driving mechanism 5 drives the first main gear 314 to rotate through the reduction driving gear 311, the first main gear 314 drives the first auxiliary gear 315 to rotate, the first auxiliary gear 315 rotates synchronously with the second auxiliary gear 316 through the first rotating shaft rod 319, the second auxiliary gear 316 drives the third auxiliary gear 317 to rotate, since the number of teeth of the first auxiliary gear 315 is greater than that of the first main gear 314, and the number of teeth of the third auxiliary gear 317 is greater than that of the second auxiliary gear 316, when the first main gear 314 drives the first auxiliary gear 315 to rotate, the rotating speed of the first auxiliary gear 315 is reduced compared with that of the first main gear 314, the rotating speeds of the first auxiliary gear 315 and the second auxiliary gear 316 are the same, and when the second auxiliary gear 316 drives the third auxiliary gear 317 to rotate, the rotating speed of the third auxiliary gear 316 is reduced compared with that of the second auxiliary gear 316, so that, through two-stage reduction, the rotating speed of the sector gear 318 is reduced compared with that of the rotating shaft 22, thereby the rotating speed of the rack bar 317 is reduced greatly compared with that of the rack bar 32 when moving up and down, and the rack bar 32 is prevented from being subjected to an over-roll movement, thereby preventing the rack bar unwinding movement.
Optionally, the speed reducing mechanism 31 further includes a transition gear 312, and the speed reducing driving gear 311 is meshed with the first main gear 314 through the transition gear 312. As shown in fig. 3 to 5, by providing the transition gear 312, the distance between the sector gears 318 corresponding to the two sets of reduction gear sets 313 can be increased, thereby increasing the width of the rack 32, improving the rigidity of the rack 32, and making the rack 32 not easily damaged.
Specifically, as shown in fig. 1 and 2, a pressing wheel 33 is disposed at one end of the rack 32 close to the unwinding rotating shaft 22, and a rotating shaft of the pressing wheel 33 is parallel to the unwinding rotating shaft 22. After the rack 32 drives the pinch roller 33 to move and press against the circumferential outer wall of the coil 6, the pinch roller 33 can rotate along with the rotation of the coil 6, so that the friction force between the pinch roller and the circumferential outer wall of the coil 6 is reduced.
It should be noted that, as shown in fig. 1 and 2, the first transmission mechanism 21 includes a first driving wheel 211 and a first driven wheel 212, the first driving wheel 211 is fixedly connected with the output shaft of the driving mechanism 5, the first driven wheel 212 is fixedly connected with the unwinding rotating shaft 22, and the first driving wheel 211 is in transmission connection with the first driven wheel 212 through an unwinding transmission belt 213. In this way, the driving mechanism 5 can drive the unwinding rotary shaft 22 to rotate through the first driving wheel 211 and the first driven wheel 212.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, and the scope of protection is still within the scope of the invention.
