[0002] In the existing technical solutions for waste removal of dome-shaped products, manual waste removal or a winding device is used for waste removal. However, after waste removal by a conventional winding device, glue overflows around the product, that is, the product is unqualified. Since the winding speed of the winding machine can only be the same as the tape speed, the stepping speed of the general tape is relatively slow and waste removal can only be carried out vertically, which will cause the product to be taken down together during waste removal, resulting in a high scrap rate.

[0003] Therefore, a tension following waste removal device for dome-shaped die-cut products is designed to solve the technical problem that in the prior art, waste removal can only be carried out vertically, resulting in glue overflow around the product after waste removal and thus the product being unqualified.

[0049] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0050] In the existing technical solutions, for the waste removal of ball-top products, manual waste removal or a winding device is used for waste removal. However, after waste removal by a conventional winding device, glue overflow will occur around the product, that is, the product is unqualified. Since the winding speed of the winding machine can only be the same as the tape speed, and generally the stepping speed of the tape is relatively slow and waste removal can only be performed from the vertical direction, it will cause the product to be taken down together during the waste removal process, resulting in a high rejection rate.

[0051] To solve the above technical problems, in at least one embodiment, as Figure 1 shown, a tensioning and following waste removal device for ball-top die-cutting products is provided, including: a bracket 4, on which a transmission line for ball-top die-cutting products is arranged; a scrap collecting and pulling mechanism 1, arranged on the non-vertical side of the transmission line for ball-top die-cutting products; wherein the scrap collecting and pulling mechanism 1 includes at least two scrap collecting and pulling rollers 15 arranged parallel to each other up and down; and the waste end of the ball-top die-cutting product is adapted to be inserted from the feeding side of the two scrap collecting and pulling rollers 15, and then during the rotation of the two scrap collecting and pulling rollers 15, the waste is collected and pulled from the non-vertical side of the transmission of the ball-top die-cutting product.

[0052] By providing a waste removing device 1 for pulling and winding, in order to achieve a waste removing direction at a specific angle, a universal rotating base 11 is added between the waste removing device 1 for pulling and winding and the bracket 4, so that the waste removing device 1 for pulling and winding can be placed on the non-vertical side of the tape tensioning device 2 to achieve the purpose of waste removing at a specific angle. At the same time, during the winding process of the waste, there will be a front-back change in the separation position, resulting in continuous changes in the winding direction of the waste removing device 1 for pulling and winding. Therefore, the universal rotating base 11 can enable the waste removing device 1 for pulling and winding to follow the continuous change of the waste separation position.

[0053] In some embodiments, as Figure 1a shown (the black arrow in the figure is the moving direction of the waste 50), the ball top die-cut product 5 is passed through the tape tensioning mechanism 2, and the tape tensioning mechanism 2 is used to tension the ball top die-cut product 5 for subsequent waste removal. After the end of the waste 50 of the ball top die-cut product 5 is separated from the ball top body, the end of the waste 50 is inserted into the waste removing device 1 for pulling and winding, and the waste removing device 1 for pulling and winding is used to pull the waste 50. And the waste removing device 1 for pulling and winding is arranged on the non-vertical side of the transmission line of the ball top die-cut product 5. At this time, waste removal starts from the sharp corner of the ball top, effectively avoiding the problem of high rejection rate caused by taking down the ball top die-cut product 5 during the waste removal process.

[0054] As Figure 1b shown (the black arrow in the figure is the moving direction of the waste 50), as the waste removal work progresses, when the ball top die-cut product 5 is transmitted to the end, the transmission of the ball top die-cut product 5 is stopped, and the tape tensioning mechanism 2 is used to clamp the remaining ball top die-cut product 5. At this time, the waste removing device 1 for pulling and winding continues to work to remove the waste of the remaining ball top die-cut product 5. As the length of the unremoved waste decreases, during the waste removal process of the waste removing device 1 for pulling and winding, the orientation of its feeding side will continuously change, that is, during the waste removal process, the universal rotating base 11 will drive the waste removing device 1 for pulling and winding to rotate to change the orientation of the feeding side of the waste removing device 1 for pulling and winding to continuously adapt to the waste removal of the ball top die-cut product 5.

[0055] In some embodiments, as Figure 2 shown, after the end of the waste 50 of the ball top die-cut product 5 is separated from the ball top body, the end of the waste 50 is inserted into the gap opened on the waste limiting plate 14, and the width of the gap is the same as the width of the waste 50, so that the waste 50 can keep moving in the same direction without deviation when passing through the winding roller 15.

[0056] In some embodiments, as Figure 3As shown, when the waste is removed, the motor 18 is started, and its output end drives the synchronous wheel 17 to start, and through the belt transmission, drives the synchronous wheel 17 fixed on the lower pulling roller 15 to rotate, and then drives the lower pulling roller 15 to rotate. At this time, the upper pulling roller 15 rotates synchronously and turns in the opposite direction to the lower pulling roller 15 (for the two pulling rollers 15, driving one pulling roller 15 to drive the other pulling roller 15 to rotate in the opposite direction is a prior art, which will not be repeated here), the end of the waste 50 passes through the gap opened on the limit plate 14 and moves between the two pulling rollers 15. As the two pulling rollers rotate and squeeze, the waste 50 is driven to be transmitted and moved out from the gap on the other waste limit plate 14 to achieve continuous waste removal.

[0057] In some embodiments, Figure 3 As shown, a little space is reserved at the connection between the take-up roller 15 and the take-up fixed plate to prevent direct friction, but it may cause the waste belt or waste debris to be rolled into or stuck in the gap, resulting in jamming. Therefore, an anti-twisting guard plate 12 is added to the side of the take-up fixed plate 16 facing the take-up roller 15 to prevent the material belt from being rolled into the gap.

[0058] In some embodiments, Figure 3 As shown, a motion protection plate 13 is provided on one side of the two synchronous wheels 17 , and the motion protection plate 13 is fixed to one of the retractable fixing plates 16 to protect the transmission of the two synchronous wheels 17 .

[0059] In some embodiments, Figure 4 As shown, the ball-top die-cut products 5 to be discarded are transmitted through the gap between the two tensioning rollers 23 in the material belt tensioning mechanism 2, and the ball-top die-cut products 5 to be discarded are tensioned by the friction between the two tensioning rollers 23 and the ball-top die-cut products 5 to be discarded.

[0060] In some embodiments, Figure 5 As shown, the end of the ball-top die-cut product 5 to be removed passes through the material belt limiting plate 25 and is inserted between the two tensioning rollers 23, and passes through the output ends of the two tensioning rollers 23 to the subsequent workstation. The ball-top die-cut product 5 to be removed is transmitted separately by the transmission device in the prior art. During the transmission process, the two tensioning rollers 23 are respectively abutted against the upper and lower end surfaces of the ball-top die-cut product 5, that is, the two tensioning rollers 23 exert a certain degree of extrusion on the ball-top die-cut product 5, so the two tensioning rollers 23 will rotate with it (for the two tensioning rollers 23, connecting the two tensioning rollers 23 by a belt so that the two rotate synchronously and turn in opposite directions is a prior art and will not be repeated here).

[0061] In some embodiments, Figure 6As shown, if it is necessary to adjust the tension of the dome-shaped die-cut product during the transmission process, simply manually rotate the screw 26 so that it penetrates into the tension fixing plate 22 that is threadedly connected to it. As the screw 26 penetrates deeper, the end of the screw 26 will push the sliding connection between the braking member 21 and the current tension fixing plate 22, and then push the braking member 21 to slide on the current tension fixing plate 22 and approach one of the tension rollers 23. The movement state is as shown in Figure 7 shown (the black straight arrow is the moving direction of the braking member 21, and the black circular arrow is the rotating direction of the tension roller 23). One side of the braking member 21 is arc-shaped. When the braking member 21 moves and abuts against the tension roller 23, a frictional force will be generated between it and the current tension roller 23, thereby reducing the rotation speed of the two tension rollers 23. At this time, the transmission speed of the dome-shaped die-cut product 5 remains unchanged, and thus the tension force of the two tension rollers 23 on the dome-shaped die-cut product 5 is increased, so that the dome-shaped die-cut product 5 remains taut, facilitating subsequent waste removal work.

[0062] In summary, by providing a pulling and waste removing device, in order to achieve a waste removing direction at a specific angle, a universal rotating base is added between the pulling and waste removing device and the bracket, so that the pulling and waste removing device can be placed on the non-vertical side of the tape tensioning device to achieve the purpose of waste removing at a specific angle. At the same time, during the winding process of the waste material, the front and rear positions of the separation position will change, resulting in continuous changes in the winding direction of the pulling and waste removing device. Therefore, the universal rotating base can enable the pulling and waste removing device to follow the changing separation position of the waste material.
