[0028] The winding device is arranged at the end of the second table, and the winding device comprises a winding shaft 2, a notch 3 arranged in the winding shaft 2, and a fixing device arranged in the notch 3 and used for fixing the waste plate, in particular, the fixing device comprises a first plate body 34 and a second plate body 35, the first plate body 34 and the second plate body 35 are both slidingly connected in the winding shaft 2, further, the first plate body 34 is vertically connected in the notch 3, the second plate body 35 is horizontally connected in the notch 3, and the first plate body 34 and the second plate body 35 are matched by a slope, the second plate body 35 can move downward after moving away from the first plate body 34, that is, the first plate body 34 is connected in the winding shaft 2 by a pressure spring 36, the second plate body 35 is connected by a stretching spring 37, and the elastic force of the stretching spring 37 is greater than that of the pressure spring 36, that is, the first plate body 34 can be arranged away from the notch 3 in a state without external force, and when the waste plate enters the notch 3 and continuously pushes the second plate body 35, the waste plate is fixed in the notch 3 under the action of the pressure spring 36.

[0029] The winding shaft 2 needs to be matched with the movement of the waste plate to rotate, and therefore, a first gear 10 is arranged at one side of the winding shaft 2, and a first rack 11 is arranged in matching with the first gear 10, in particular, the first rack 11 is connected with the first moving block 7, that is, when the first moving block 7 moves, the first rack 11 moves to drive the first gear 10 to rotate and wind the winding shaft 2.

[0030] Therefore, the auxiliary linear module can realize that the winding shaft 2 is matched to rotate to wind the waste plate on the winding shaft 2 after the first moving block 7 moves, the first moving block 7 repeatedly moves upward in the first guide rail 5, therefore, the first gear 10 is arranged on the winding shaft 2 by a one-way bearing, when the first moving block 7 moves toward the winding shaft 2, the first gear 10 drives the winding shaft 2 to rotate, when the first moving block 7 moves away from the winding shaft 2, the first gear 10 cannot drive the winding shaft 2 to rotate, and the first rack 11 and the first moving block 7 are connected by a connecting rod.

[0031] Because the waste plate has a protruding area after being punched, which is not conducive to winding, a straightening device is arranged between the winding device and the workbench 1, the straightening device comprises a first straightening roller 27 and a second straightening roller 28, the straightening rollers are rotationally connected to the base by assembly, the first straightening roller 27 is arranged above the second straightening roller 28, therefore, the first straightening roller 27 is arranged on the base by a lifting sliding block 29, a compression spring 31 is arranged at the bottom of the sliding block 29, a screw rod 30 is arranged at the top of the sliding block 29 in abutment, and the screw rod 30 is matched and connected in the base, when the screw rod 30 moves downward, the two groups of straightening rollers are close to each other, and the thickness of the matched plate can be changed.

[0032] At the same time, in order to realize the timely replacement when the thickness of the plate around the shaft 2 reaches the set threshold value, a cutting device is arranged on one side of the support frame 4, the cutting device comprises a second rod body 32 and a movable blade 33, the blade 33 is slidingly arranged in the support frame 4, the second rod body 32 is arranged in parallel with the normally working notch 3, when the blade 33 moves towards the second rod body 32, the plate is cut off, in order to realize the lifting of the blade 33, the two ends of the blade 33 are connected through a micro cylinder, when the piston rod of the micro cylinder completes the extension and retraction, the blade 33 completes one extension and retraction, and the cutting is realized.

[0033] The separated waste plate needs to be further separated, specifically, a plurality of shafts 2 are arranged in the support frame 4, the shafts 2 are slidingly arranged in the support frame 4 through the mounting piece 44, and an extension device is arranged in the support frame 4 for temporarily fixing the position of the shaft 2, specifically, the extension device comprises a cam 24, a motor and a first spring 25, movable clamping blocks 26 are arranged on both sides of the mounting piece 44, when the clamping blocks 26 are located below the mounting piece 44, the mounting piece 44 and the shaft 2 are fixed, at the same time, after the clamping blocks 26 are located in the support frame 4, the mounting piece 44 and the shaft 2 move downward, in order to control the position of the clamping blocks 26, the motor is arranged in the support frame 4, the motor is connected with the cam 24, the cam 24 abuts against the clamping blocks 26, the clamping blocks 26 pass through the first spring 25, the first spring 25 is arranged between the clamping blocks 26 and the support frame 4, so that when the clamping blocks 26 are pushed out by the cam 24, the clamping blocks 26 are restored under the action of the first spring 25 when they are not pushed, when the cam 24 rotates one circle, the shafts 2 correspondingly move downward one step.

[0034] Control blocks are arranged on the two groups of linear modules, first and second switches 22 and 23 are arranged on both sides of the first electromagnet, the first and second switches 22 and 23 are elastic buttons, a first control block 20 is arranged on the left side of the linear module, when the first switch 22 of the first electromagnet contacts the first control block 20, the first electromagnet is started, and the clamping block 18 clamps the plate, and in the same way, when the second switch 23 of the first electromagnet contacts the second control block 21 on the right side, the second electromagnet 42 is closed, and the clamping block 18 does not clamp the plate.

[0035] Because the replacement of the winding shaft 2 needs a certain time, in order to match the time, the first gear 10 is connected with the servo motor 38 through the fixed block 9, when the winding shaft 2 is replaced, the second rack 39 is arranged on the other side of the first rack 11, the length of the second rack 39 is shorter than the first rack 11, the servo motor 38 is started to realize that the first rack 11 rotates 180 degrees, then the second rack 39 acts on the first gear 10, at the same time, the second control block 21 is sleeved in the sleeve 40, the second control block 21 is connected in the sleeve 40 through the second spring 41, the second electromagnet 42 arranged in the sleeve 40 is started, the control block is magnetically adsorbed on the electrified second electromagnet 42, the elastic force of the second switch 23 is greater than the second spring 41, when the second electromagnet 42 is not electrified, the second switch 23 is triggered only after overcoming the elastic force of the second spring 41.

[0036] The auxiliary linear module and the feeding linear module realize the control of the distance of the sliding block and the moving block through the control device, therefore, when the winding shaft 2 is replaced, the distance of the sliding block and the moving block moving towards the winding shaft 2 is increased to be equivalent to the distance of the second control block 21 moving, in the lengthened moving distance, it is ensured that the winding shaft 2 is replaced, the inductive switch 43 is arranged in the support frame 4, when the plate material is wound around the inductive switch 43, the moving block contacts the second control block 21, then the cutting device is started, the telescopic device is started to replace the winding shaft 2.

[0038] When the plate around the shaft 2 reaches the position of the inductive switch 43, and the moving block and the slider just contact the second control block 21, and then move to the first control block 20, the cutting device starts, the shaft 2 separates, at the same time, on the one hand, the telescopic device starts, that is, the motor drives the cam 24 to rotate a circle, the shaft 2 moves down a layer to complete the replacement, on the other hand, in order to increase the distance of the plate movement, the servo motor 38 drives the first rack 11 to rotate, the second electromagnet 42 is de-energized, and the distance of the moving block increases, when the plate re-enters the slot 3, the second plate body 35 moves, the plate is fixed on the shaft 2, at this time, the second gear rotates and the first gear 10 contacts to drive the shaft 2 to rotate, realizing the rotation of the reel during feeding, until the second switch 23 and the second control block 21 trigger, the moving block and the slider move away from the shaft 2, the second electromagnet 42 starts, the moving distance of the moving block and the second slider 15 returns to the initial setting, and the servo motor 38 rotates to the first rack 11 to act on the first gear 10, so that the winding device can work normally and automatically replace.
