The device includes a slitting mechanism at the output end of the die-cutting machine, an anti-static eliminator on the side of the slitting mechanism away from the die-cutting machine, and a collection box below the anti-static eliminator.

Detailed Implementation
[0028] The present invention will be further described below with reference to the accompanying drawings:
[0029] The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0030] like Figures 1 to 11As shown, an antistatic device for self-adhesive paper coating production includes a die-cutting base 1. The die-cutting base 1 is sequentially fixedly connected to an infeed roller assembly 2, an antistatic seat 3, an outlet roller assembly 4, a constant humidity chamber 5, and a bagging mechanism 6. Below the bagging mechanism 6 is an outlet rack 7 fixedly connected to the die-cutting base 1. The outlet rack 7 has a downward-sloping outlet side to facilitate moving the self-adhesive paper rollers to the outlet for easy transportation and storage. The bagging mechanism 6 includes a first drive device 601 fixedly connected to the die-cutting base 1 and located on one side of the outlet rack 7. The first drive device 601 is a drive motor. A splined shaft 6011 is fixedly connected to the extended end of the first drive device 601. An active column 611 is slidably connected to the periphery of the splined shaft 6011. A telescopic rod 603 is slidably connected to one end of the active column 611. That is, while the active column 611 rotates with the splined shaft 6011, the telescopic rod 603 remains in contact with the active column 611, extending and retracting. On the other side of the discharge rack 7, there is a rotating frame 6066 rotatably connected to the die-cutting seat 1. The rotating frame 6066 is "L"-shaped. A folding frame 606 is fixedly connected to the shorter end of the rotating frame 6066. The folding frame 606 is circular, and multiple ring frames 6061 are fixedly connected to its outer side to facilitate the rotation of the rotating frame 6066. The antistatic bag can be placed on the ring frame 6061. A hollow threaded column is fixedly connected in the middle of the folding frame 606. A threaded rod 609 is threadedly connected to the threaded column. One end of the threaded rod 609 is fixedly connected to a second splined shaft 607, which serves to fix it. The second splined shaft 607 is on the same axis as the first splined shaft 6011. A driven column 608 is slidably connected to the outer periphery of the second splined shaft 607. A magnet is provided on the side of the second splined shaft 607 near the driven column 608. Under normal circumstances, the second splined shaft 607 attracts the driven column 608, keeping it close to one side. A telescopic rod 605 is movably connected to one side of the driven column 608. A fixed rod 6062 is fixedly connected to the shorter end of the rotating frame 6066 near the middle side of the discharge frame 7. A spring 6063 is nested on the outside of the fixed rod 6062. One end of the spring 6063 abuts against the rotating frame 6066, and a baffle 6064 is fixedly connected to the other end of the spring 6063. The baffle 6064 is slidably connected to the fixed rod 6062. An arc-shaped stop head 6065 is fixedly connected to the end of the fixed rod 6062 near the baffle 6064.
[0031] A support frame 503 is fixedly connected to the side of the constant humidity chamber 5 near the bagging mechanism 6. A bidirectional lead screw 604 is rotatably connected to one end of the support frame 503. The bidirectional lead screw 604 is located above the first drive device 601 and is parallel to the axis of the spline shaft 6011. Limiting plates 6042 are fixedly connected to both ends of the bidirectional lead screw 604. A stop block 6041 is fixedly connected to the outer side of the limiting plate 6042 near the folding frame 606. A first servo 602 is fixedly connected to the die-cutting seat 1 above the first drive device 601. The extended end of the first servo 602 is fixedly connected to the bidirectional lead screw 604. Telescopic rod 603 and telescopic rod 605 are threaded to both ends of the bidirectional lead screw 604, respectively. The doubly threaded screw 604 has one less thread thickness than the telescopic rod 605 on the side closest to it, and the thread density on the other side is twice that of the first side. The advantage of this design is that when the doubly threaded screw 604 drives the telescopic rod 605 to rotate outwards, due to the missing thread, when the telescopic rod 605 rotates to the unthreaded position, the stop block 6051 on the telescopic rod 605 abuts against the stop block 6041 on the doubly threaded screw 604, allowing the insert block 6054 to be inserted into the slot 6083. The different thread densities allow for different thread thicknesses on both sides... The telescopic rod 603 and telescopic rod 605 move forward synchronously. The spline shaft 607 attracts the driven column 608 to ensure that the insert 6054 is inserted into the slot 6083. When the double-acting screw 604 drives the telescopic rod 605 to rotate inward, the double-acting screw 604 first rotates a few times, and the stop block 6041 abuts against the other side of the stop block 6051 to move the insert 6054 out of the slot 6083 and insert the insert 6054 into the slot 6083. The main function of the insert 6054 is to facilitate handling when the antistatic bag is damaged, the drawstring comes off, or the hook 6124 slips off.
[0032] Above the discharge rack 7, near the lower side of the discharge port of the constant humidity chamber 5, a second servo 610 is fixedly connected. The extended end of the second servo 610 is fixedly connected to a lead screw 613. One end of the lead screw 613 is rotatably connected to the constant humidity chamber 5. A traction device 612 is threadedly connected to the lead screw 613. The traction device 612 includes a traction block 6121 threadedly connected to the lead screw 613. One end of the traction block 6121 is slidably connected to the constant humidity chamber 5. A hook 6124 is rotatably connected to one side of the other end of the traction block 6121. One end of the hook 6124 abuts against the fixed rod 6062 and the arc-shaped stop 6065. A second spring 6123 is fixedly connected to the other side of the other end of the traction block 6121. One end of the second spring 6123 is fixedly connected to the hook 6124. A cutter head 6122 is fixedly connected above the traction block 6121.
[0033] Inside the driving column 611, there is a second spline groove 6111 that mates with the first spline shaft 6011. On the outer side of the driving column 611, there is a sliding groove 6112, and the sliding groove 6112 is a "convex" - shaped groove. The first telescopic rod 603 includes a first threaded ring 6031 that is threadedly connected to the bidirectional lead screw 604. On the outer side of the first threaded ring 6031, there is a fixedly connected first connecting rod 6032. One end of the first connecting rod 6032 is fixedly connected to an arc plate 6033. The arc plate 6033 is slidably connected with the sliding groove 6112 in a mating manner. That is, when the sliding groove 6112 rotates, the arc plate 6033 can remain stationary, and the arc plate 6033 only drives the driving column 611 to move left and right.
[0034] Inside the driven column 608, there is a first spline groove 6081 that is slidably connected with the second spline shaft 607 in a mating manner. At one end on the outer side of the driven column 608, there is a fixedly connected bearing 6082. At the other end on the outer side of the driven column 608, there is a slot 6083. The second telescopic rod 605 includes a second threaded ring 6052 that is threadedly connected to the bidirectional lead screw 604. On one side of the second threaded ring 6052, there is a fixedly connected second stopper 6051. The second stopper 6051 abuts against the first stopper 6041. At one end on the outer side of the second threaded ring 6052, there is a fixedly connected second connecting rod 6053. One end of the second connecting rod 6053 is fixedly connected to an insertion block 6054. The insertion block 6054 is movably connected with the slot 6083.
[0035] On one side of the static - electricity eliminating seat 3 close to the die - cutting seat 1, there is a fixedly connected static - electricity eliminator 301, which can eliminate most of the static electricity on the self - adhesive paper. On the top of the humidity - constant box 5, there is a fixedly connected water tank 501. The water tank 501 is connected to the humidity - constant box 5. On one side of the humidity - constant box 5, there is a fixedly connected humidity sensor 502 to detect the humidity inside the humidity - constant box 5. When the humidity is low, the water inside the water tank 501 will enter the humidity - constant box 5 to control the humidity inside the humidity - constant box 5, ensuring that the humidity in the humidity - constant box 5 always remains between 40% and 60%.
[0036] In this utility model, the first servo 602 and the second servo 610 used are both servo motors. The advantage of using servo motors is that the control of rotation is more precise, the rotation angle is controllable, and there is no possibility of collision between parts.
[0037] Those skilled in the art can use the existing technologies they master, such as installing corresponding mechanical limit switches or photoelectric sensors to define the specified positions of each executing component in the following action process; to achieve automated operation, this utility model can adopt numerical control technology or PLC to control the actions of each executing component.
[0038] Working process: Rotate the folding frame 606 to one side, place multiple antistatic bags with openings on both sides on the outside of the ring frame 6061, and loop the drawstring on one side of the antistatic bag onto the fixing rod 6062. The bag is held in place by the baffle 6064. Close the folding frame 606, and then place the self-adhesive paper roller between the driven column 608 and the driving column 611. Start the first servo 602 to drive the bidirectional lead screw 604 to rotate. The telescopic rods 603 and 605 on both sides drive the driving column 611 and the driven column 608 to move towards the middle and insert into the middle of the self-adhesive paper roller.
[0039] The first drive unit 601 is activated, driving the spline shaft 6011 to rotate. The spline shaft 6011 drives the drive column 611 to rotate, which in turn drives the self-adhesive paper roller to rotate. The self-adhesive paper roller enters from the infeed roller group 2, and after most of the static electricity is eliminated by the static eliminator 301, it exits from the outfeed roller group 4 and enters the constant humidity chamber 5. When the humidity reaches 40% to 60%, the self-adhesive paper returns to the self-adhesive paper roller. When the thickness of the self-adhesive paper on the self-adhesive paper roller reaches the standard, the second servo 610 is activated, driving the lead screw 613 to rotate. The traction device 612 on the lead screw 613 moves, and when the hook 6124 moves forward, it hooks the frontmost drawstring. Due to the obstruction of the arc-shaped stop 6065, the hook 6124 will retract to one side. After the hook 6124 comes out with the drawstring, it will rebound under the action of the second spring 6123. When the traction block 6121 moves with the drawstring... At this time, the cutter head 6122 at the top of the traction block 6121 will cut the self-adhesive paper, that is, cutting the self-adhesive paper box and bagging the self-adhesive paper roller are carried out simultaneously. When the hook 6124 moves the closing rope from one end of the self-adhesive paper roller to the other end, that is, after the anti-static bag covers the self-adhesive paper roller, the second servo 610 drives the lead screw 613 to reverse, driving the traction device 612 to move backward. The hook 6124 automatically disengages from the closing rope. After disengagement, the first servo 602 drives the bidirectional lead screw 604 to move in the direction. The first telescopic rod 603 and the second telescopic rod 605 each drive the active column 611 and the driven column 608 to move backward. The self-adhesive paper roller falls from above and lands on the discharge rack 7, waiting for the staff to process and store it.
[0040] After completing the above steps, continue placing the self-adhesive roller on the driving column 611 and the driven column 608, and repeat the above steps. Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
