DETAILED DESCRIPTION OF THE INVENTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0020] Embodiment: As Figure 1-7 shown, the present utility model provides a feeding device for a slitting machine, including a bottom plate 1. A slitting mechanism 11 is fixedly arranged on the upper surface of the bottom plate 1. A winding mechanism 12 is fixedly arranged on the upper surface of one end of the bottom plate 1 close to the slitting mechanism 11. A fixing plate 2 is fixedly arranged on the upper surface of the other end of the bottom plate 1 far from the winding mechanism 12. A rotating cylinder 21 is rotatably arranged on one side of the fixing plate 2. A plurality of uniformly distributed adjusting disks 22 are rotatably arranged inside the rotating cylinder 21. A plurality of adjusting grooves 23 distributed in an annular array are respectively formed in the adjusting disks 22. An adjusting block 24 is slidably arranged in each adjusting groove 23. One end of each adjusting block 24 is fixedly provided with an adjusting plate 25. The end of the adjusting plate 25 far from the adjusting block 24 slidably penetrates through one side wall of the rotating cylinder 21 and is located outside. An expanding plate 26 is fixedly arranged at the end of the adjusting plate 25 far from the adjusting block 24. A transmission rod 210 is fixedly inserted into the adjusting disks 22 together. The transmission rod 210 is rotatably installed on the inner wall of the rotating cylinder 21.

[0021] Vertical plates 3 distributed in a mirror image are fixedly arranged on the upper surface of one end of the bottom plate 1 close to the fixing plate 2. A screw rod 31 is rotatably arranged in each vertical plate 3. A lifting block 32 is threadedly sleeved on the outside of each screw rod 31. A stretching roller 33 is rotatably arranged on the side of the lifting blocks 32 close to each other.

[0022] A rotating shell 220 is rotatably arranged on the outer wall of the side of the fixing plate 2 far from the rotating cylinder 21. A worm gear 230 is rotatably arranged in the rotating shell 220. A worm 240 is meshed with one side of the worm gear 230. One end of the transmission rod 210 rotatably penetrates through one side wall of the rotating cylinder 21 and is located outside. The end of the transmission rod 210 far from the rotating cylinder 21 rotatably penetrates through one side wall of the fixing plate 2 and the rotating shell 220. The end of the transmission rod 210 far from the rotating cylinder 21 is fixedly installed on one side wall of the worm gear 230. One end of the worm 240 is fixedly provided with a handle 250. The end of the handle 250 rotatably penetrates through one side wall of the rotating shell 220 and is located outside.

[0023] On one side wall of the worm gear 230 away from the transmission rod 210, a first stabilizing rod 260 is fixedly installed. One end of the first stabilizing rod 260 away from the worm gear 230 is rotatably installed on the inner wall of the rotating shell 220. One end of the worm 240 away from the handle 250 is fixedly provided with a second stabilizing rod 270. One end of the second stabilizing rod 270 away from the handle 250 is rotatably installed on the inner wall of the rotating shell 220. By setting the first stabilizing rod 260, the worm gear 230 can be stably moved. By setting the second stabilizing rod 270, the worm 240 can be stably rotated.

[0024] The adjusting plates 25 are distributed in two groups. A limiting member 280 is slidably sleeved outside each group of adjusting plates 25. The limiting member 280 is fixedly installed on the inner wall of the rotating cylinder 21. The transmission rod 210 rotatably penetrates through the limiting member 280. By setting the limiting member 280, the effect of limiting the adjusting plates 25 is achieved, so that the adjusting plates 25 can move stably.

[0025] At the bottom ends of the screw rods 31, connecting rods 310 are fixedly installed. The bottoms of the connecting rods 310 rotatably penetrate through the bottom plate 1. Synchronous wheels 320 are fixedly installed outside one ends of the connecting rods 310. A belt 330 is provided for transmission between the synchronous wheels 320.

[0026] A motor 340 is provided at the bottom end of one of the connecting rods 310. One of the connecting rods 310 is coaxially and fixedly installed with the driving end of the motor 340.

[0027] On the outer walls on both sides of the lifting block 32, guiding blocks 350 are fixedly installed. Guide rods 360 are slidably inserted into the guiding blocks 350. The top ends of the guide rods 360 are fixedly installed on the inner upper surface of the vertical plate 3. The bottom ends of the guide rods 360 are fixedly installed on the upper surface of the bottom plate 1. By setting the guiding blocks 350 and the guide rods 360, the effect of limiting the lifting block 32 is achieved, so that the lifting block 32 can move stably.

[0028] Working principle: First, during use, place the large roll of tape on the outside of the plurality of expanding plates 26. Subsequently, drive the handle 250 to rotate. During the rotation of the handle 250, the operator fixes the rotating cylinder 21 to prevent the rotating cylinder 21 from rotating during the rotation of the handle 250. The handle 250 drives the worm 240 to rotate. The worm 240 drives the worm gear 230 to rotate. The worm gear 230 drives the transmission rod 210 to rotate. The transmission rod 210 drives the adjusting disc 22 to rotate. During the rotation of the adjusting disc 22, it drives the adjusting groove 23 to perform a circular motion. During the circular motion of the adjusting groove 23, it drives the adjusting plate 25 to move. The adjusting plate 25 drives the expanding plate 26 to move. When the expanding plate 26 is in close contact with the inner wall of the tape roll, remove the driving force on the handle 250 to complete the fixation of the large roll of tape.

[0029] Subsequently, the motor 340 is started. The motor 340 drives one of the connecting rods 310 to rotate. One of the connecting rods 310 drives the other connecting rod 310 to rotate through the synchronous pulley 320 and the belt 330. The connecting rod 310 drives the screw rod 31 to rotate. During the rotation of the screw rod 31, the lifting block 32 is driven to move. The lifting block 32 drives the stretching roller 33 to move. During the movement of the stretching roller 33, the tape between the expansion plate 26 and the winding mechanism 12 is straightened. When the stretching roller 33 moves to a position where the tape does not sag, the motor 340 is turned off.

[0030] Obviously, those skilled in the art can make various modifications and variations to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these modifications and variations.
