A plurality of second gears 8 which can be meshed with the first gear 5 and whose diameters increase sequentially from left to right are fixed coaxially on the outer side of the shaft.

In order to realize the support of the reeling roller 1 , a support frame 9 is provided below the reeling roller 1 , and the mandrels at both ends of the reeling roller 1 are detachably mounted on the support frame 9 .

In order to facilitate the forward and backward movement of the baffle 2 and the synchronous forward and backward movement of the drive motor 6 following the baffle plate, a first support platform 10 is provided below the support rod 3 , and the upper end surface of the first support platform 10 is provided with a first slideway in the front and rear directions. 11. The lower end surface of the support rod 3 is fixed with a first slider 12 that can slide in the first slideway 11; a second support platform 13 is provided below the drive motor 6, and the upper end surface of the second support platform 13 is provided with front and rear directions. The lower end surface of the driving motor 6 is fixed with a second sliding block 15 slidable in the second slideway 14 .

In order to realize that the baffle 2 can move forward and can be reset back, the rear end of the support rod 3 is connected with a second compression spring 16, one end of the second compression spring 16 is fixed on the support rod 3, and the other end is fixed with the first compression spring 16. on the support platform 10 .

In order to facilitate the baffle 2 to squeeze the cable, the baffle 2 is shaped such that the middle is a plane and the left and right ends are respectively tilted forward.

In order to realize that the first gear 5 can rotate synchronously with the rotating shaft 4 while sliding left and right, the first gear 5 and the rotating shaft 4 are connected by splines.

In order to realize the fixing of the plurality of second gears 8, the plurality of second gears 8 are coaxially mounted on a transmission shaft, a bracket is provided below the plurality of second gears 8, and the right end of the transmission shaft is connected to the coil through the coupling. Line roll 1 mandrel connection.

The specific working process of the utility model is as follows: when the device is in use, the mandrels at both ends of the reel 1 are placed on the support frame 9 so that the left end of the mandrel is exposed to the support frame 9. At this time, the mandrel and the first The transmission shafts on the two gears 8 are connected, and the first gear 5 is moved to the left so that the first gear 5 meshes with the second gear 8 at the leftmost end. During this process, the first compression spring 7 is compressed and has a tendency to rebound and elastic potential energy. At this time, the baffle 2 is in contact with the roller body of the winding roller 1, and at the same time, one end of the cable is first fixed and wound around the winding roller 1 to ensure that the rotation of the winding roller 1 can drive the cable to be repeatedly wound on the winding roller 1. .

Turn on the rotation of the drive motor at 6 points to drive the first gear 5 to rotate, the first gear 5 meshes with the second gear 8 with the smallest diameter to rotate, the second gear 8 rotates through the transmission shaft and drives the reel 1 to rotate, and the reel 1 starts to drive the cable Winding on it, as the number of winding turns of the cable increases, the cable wound on the winding roller 1 starts to push the baffle 2 to move forward, and the baffle 2 moves forward while squeezing the second compression spring 16 and making it It has a tendency to rebound and elastic potential energy. At the same time, the forward movement of the baffle plate 2 makes the first slider 12 slide in the first slideway 11, and at the same time, under the action of rotation, the second slider 15 will also slide in the second slider 15. The slideway 14 slides inside, so that the drive motor 6 moves forward and backward with the baffle 2. With the forward movement of the baffle 2, the rotating shaft 4 moves forward, and the first gear 5 moves forward. During this process, the first gear 5 and the The former second gear 8 disengages, moves to the right under the action of the first compression spring 7 with a tendency to reset, and meshes with the next second gear 8 with a slightly larger diameter, thereby realizing the deceleration of the winding roller 1 .

By analogy, as the cable on the winding roller 1 increases, the baffle 2 drives the rotating shaft 4 to move forward, and the diameter of the second gear 8 meshing with the first gear 5 increases gradually, thereby realizing the lowering of the winding roller 1. speed.

The obvious advantages of this device: the device is arranged to be close to the winding roller 1 by setting the baffle 2, and according to the winding thickness of the cable on the winding roller 1, the baffle 2 is driven to move forward, and through the movement of the baffle 2, the first The gear 5 meshes with the second gear 8 whose diameter gradually increases, so as to reduce the angular velocity of the winding roller 1 under the principle that the angular velocity does not change when the number of cables wound on the winding roller 1 increases, and the angular velocity of the winding roller 1 is reduced. The linear velocity always maintains a relatively stable value.

The utility model has novel conception, ingenious structure and strong practicability. By gradually reducing the angular velocity of the reeling roller, it solves the problem of excessively fast winding of the cable caused by the increase of the wire speed of the reeling roller when the amount of the cable wound on the reeling roller increases.
