Description

Technical Field

[0001] This utility model relates to the field of die-cutting machine technology, and in particular to a self-adhesive separation mechanism for die-cutting machines. Background Technology

[0002] Self-adhesive labels are composite materials made of paper, film, or special materials as the face stock, coated with adhesive on the back, and with silicone-coated release paper as the backing paper. Die-cutting machines can die-cut the face stock into specific shapes for easy use. Currently, some self-adhesive labels, after being die-cut by a die-cutting machine, have their face stock cut into multiple small discs, and the portion of the face stock without the small discs needs to be peeled off from the backing paper. This application provides a self-adhesive label separation mechanism to peel off the portion of the face stock without the small discs (hereinafter referred to as waste face stock) from the backing paper. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a self-adhesive separation mechanism for a die-cutting machine, addressing the aforementioned technical deficiencies.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a self-adhesive separation mechanism for a die-cutting machine, including a frame, drive rollers driven by a first motor are rotatably connected to the left and right sides of the frame, a pressure roller is rotatably connected to the frame above the drive rollers, a lifting plate is provided in the middle of the frame, the lifting plate is inclined to the plane containing the axes of the two drive rollers, guide columns with the same inclination direction as the lifting plate are provided on the front and rear sides of the frame, slide blocks are slidably connected to the guide columns, a spring is provided between the slide block and one end of the guide column, the two ends of a second guide roller are rotatably connected to the two slide blocks respectively, a winding shaft driven by a second motor is rotatably connected to the upper part of the middle of the frame, and a first guide roller is rotatably connected to the frame below the winding shaft.

[0005] To further optimize this technical solution, a sprocket is provided at one end of each of the two drive rollers, and the chain is connected to the two sprockets for transmission.

[0006] To further optimize this technical solution, the end of the guide post away from the lifting plate is provided with a threaded part, and a nut is connected to the threaded part.

[0007] To further optimize this technical solution, a winding cylinder is provided on the winding shaft.

[0008] Compared with the prior art, this utility model has the following advantages: Roller groups consisting of drive rollers and pressure rollers are provided on both the left and right sides of the frame, and a lifting plate is provided in the middle of the frame. The waste fabric passes through the lifting plate, the second guide roller and the first guide roller in sequence and is wound on the winding shaft, thereby separating the waste fabric from the base paper. Since the slide can move relative to the guide column, the second guide roller can move to buffer and prevent damage to the base paper due to excessive tension. Attached Figure Description

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Detailed implementation method: combined with Figure 1 As shown, a self-adhesive label separating mechanism for a die-cutting machine includes a frame 1. Drive rollers 3, driven by a first motor, are rotatably connected to both the left and right sides of the frame 1. A pressure roller 2 is rotatably connected to the frame 1 above the drive rollers 3. The self-adhesive label passes between the drive rollers 3 and the pressure roller 2. Rotation of the drive rollers 3 causes the self-adhesive label to move. A lifting plate 4 is provided in the middle of the frame 1. The lifting plate 4 is inclined to the plane containing the axes of the two drive rollers 3, i.e., inclined to the length direction of the self-adhesive label and parallel to the width direction of the self-adhesive label. Lifting plates inclined to the lifting plate 4 are provided on the front and rear sides of the frame 1. Guide columns 9 are aligned in the same direction, and slide blocks 8 are slidably connected to the guide columns 9. A spring is provided between the slide blocks 8 and the end of the guide columns 9 near the lifting plate 4. The two ends of the second guide roller 7 are rotatably connected to the two slide blocks 8 respectively. The axis of the second guide roller 7 is parallel to the axis of the drive roller 3. A winding shaft 5 driven by a second motor is rotatably connected above the middle of the frame 1 (the speed of the second motor can decrease accordingly as the winding thickness on the winding shaft 5 increases, i.e., the number of rotations increases, which is existing technology). A first guide roller 6 is rotatably connected to the frame 1 below the winding shaft 5. This device also includes a controller, which can be installed in the same control cabinet as the controller of the die-cutting machine.

[0013] Furthermore, each of the two drive rollers 3 has a sprocket at one end. The two sprockets are of the same specification and are connected to the chain for transmission. One of the drive rollers 3 is connected to the first motor for transmission, so that the two drive rollers 3 can rotate synchronously.

[0014] Furthermore, the end of the guide post 9 away from the lifting plate 4 is provided with a threaded part, which is connected to a nut. The nut can prevent the slide 8 from falling off the guide post 9, and the nut can play a positioning role. In the natural state, the slide 8 is in contact with the nut under the action of the spring.

[0015] Furthermore, a winding drum is provided on the winding shaft 5, on which waste fabric can be wound, and the winding drum can be unloaded from the winding shaft 5. The presence of the winding drum eliminates the need for the waste fabric to be directly wound onto the winding shaft 5.

[0016] When using, combine Figure 1 As shown, the die-cut self-adhesive (at this point, the backing paper is basically undamaged while multiple small round pieces are cut out of the fabric) passes through two sets of rollers consisting of drive roller 3 and pressure roller 2 from right to left. The waste fabric (with multiple round holes on it) passes through the peeling plate 4 to the right, under the second guide roller 7, and then upward and leftward, passing under the first guide roller 6. After that, it is wound upward onto the winding drum. The backing paper with multiple small round pieces of fabric pasted on it extends to the left continuously so that it can be collected by the subsequent mechanism. As shown in the figure, the round holes on the waste fabric are arranged in rows. Along the length direction, the adhesion between the parts of the waste fabric with and without round holes and the backing paper differs significantly. When the part of the waste fabric without round holes moves to the left side of the peeling plate 4, due to the greater adhesion between the waste fabric and the backing paper, it will move a further distance to the left before being peeled off. At this time, the second guide roller 7 is pulled to move a distance to the lower left along the guide post 9 for buffering, to prevent damage to the backing paper. When the part of the waste fabric with round holes is peeled off the backing paper, the second guide roller 7 returns to its original position. Preferably, the waste fabric on both sides of the second guide roller 7 is parallel to each other, so that after the second guide roller 7 is moved, the change in the angle between the waste fabric and the second guide roller 7 will not increase the force required for the second guide roller 7 to continue moving to the lower left along the guide post 9 (this increased force will lead to increased tension on the waste fabric and the backing paper), thus preventing it from being superimposed on the increased force due to the compression of the spring.

[0017] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
