Technical Field
[0001] This utility model relates to the field of waste removal technology for die-cutting machines, and specifically to a waste removal mechanism for die-cutting machines. Background Technology
[0002] Die-cutting machines, also known as CNC punching machines, are mainly used for die-cutting (full cut, half cut), creasing, and hot stamping of non-metallic materials, self-adhesive labels, double-sided tapes, electronic components, mobile phone pads, etc. The material strip on a die-cutting machine generally includes a base film and the product to be processed. The product is placed on the base film. After die-cutting, waste material is generated and needs to be removed from the base film. The product remains on the base film for subsequent processing. Based on the relative positions of the product and waste material on the base film, the waste material can generally be divided into inner frame waste and outer frame waste. Inner frame waste is usually discontinuous. The conventional method for removing inner frame waste is to attach waste removal tape to the material strip. Chinese patent CN220840467U discloses a waste removal mechanism for a die-cutting machine that facilitates waste collection. It includes a first conveying unit and a belt conveyor. The first conveying unit includes a support, a drive roller, a driven roller, and guide rollers. The drive roller, driven roller, and guide rollers are all rotatably mounted on the support. The guide rollers are a pair and arranged vertically. The material belt passes sequentially through the upper and lower guide rollers. The cooperation between the driven roller and the guide rollers separates the material belt's travel direction from its feeding direction. The feed end of the belt conveyor is mounted on the drive roller. The beneficial effect of this invention is that after the material belt passes the guide rollers, its travel direction changes. The inner frame waste material on the material belt, due to its rigidity, will lift off the bottom film and continue moving along the material belt's feeding direction, entering the belt conveyor and being discharged. The product follows the material belt along the changed travel direction, ensuring that the inner frame waste is not missed.
[0003] The existing technology has the following shortcomings: In the existing technology, after the material belt passes through the guide roller, the direction of travel changes. Because of its rigidity, the inner frame waste material on the material belt will lift off the bottom film and continue to move along the feeding direction of the material belt, entering the belt conveyor and being discharged. In actual use, this method easily causes the finished product to lift along with the inner frame waste material. Therefore, a waste discharge mechanism for a die-cutting machine is provided to solve the above problems. Utility Model Content
[0004] To solve the technical problems mentioned in the background, the technical solution adopted by this utility model is: a waste removal mechanism for a die-cutting machine, comprising: a die-cutting machine body, first fixing plates symmetrically arranged on both sides of the discharge end of the die-cutting machine body, a guide roller connected to the first fixing plate via a shaft, a fixing block arranged on the outer side of the first fixing plate near the end of the guide roller, a limit roller connected to the fixing block via a shaft, a screw rod connected to one side of the first fixing plate near the fixing block, an arc-shaped guide plate connected through the screw rod, a separating plate connected to one end of the arc-shaped guide plate near the limit roller, and a separating roller connected to the bottom of the separating plate via a shaft.
[0005] As a preferred technical solution of this utility model, the number of the distributing rollers is set to several, and the distance between the distributing rollers is the same. The distributing plate is connected to one end of the arc-shaped guide plate with an insert block. The insert block is inserted into the arc-shaped guide plate and fixed with screws.
[0006] As a preferred embodiment of this utility model, a material belt runs through the guide roller and the arc-shaped guide plate, and the surface of the material belt is adhered with cutting material and inner frame waste.
[0007] As a preferred embodiment of this utility model, the material distribution roller is matched with the material cutter, and the spacing between the plurality of material distribution rollers matches the waste material in the inner frame.
[0008] As a preferred embodiment of this utility model, the screw rod is fitted with a spring between the arc-shaped guide plate and the first fixing plate, and a nut is threaded to one end of the screw rod that passes through the arc-shaped guide plate.
[0009] As a preferred technical solution of this utility model, the main body of the die-cutting machine is symmetrically fixedly connected to the two sides above the first fixed plate. A waste material winding motor is fixedly installed on the outer side of one end of the second fixed plate. The output end of the waste material winding motor passes through the second fixed plate and is connected to a first winding roller. The first winding roller winds the inner frame waste material.
[0010] As a preferred technical solution of this utility model, the main body of the die-cutting machine is fixedly connected to a third fixed plate on one side below the first fixed plate. A finished product winding motor is fixedly installed on the outer side of one end of the third fixed plate, and the output end of the finished product winding motor passes through the third fixed plate and is connected to a second winding roller.
[0011] This utility model has the following advantages: When the material belt is discharged from between the guide roller and the arc-shaped guide plate, the cut material on the material belt is always held in place by the arc-shaped guide plate and the separating roller, effectively preventing the cut material from lifting off the material belt. Since the cut material is held by the separating roller, the inner frame waste is dragged and directly separated from the cut material, thus avoiding the situation where the inner frame waste and the cut material are lifted off the material belt together. This effectively ensures that the cut material will not be lifted off and taken away when discharging waste, thereby ensuring production quality, reducing losses, and having a compact structure and simple operation.

[0020] The present invention will be further described below with reference to the accompanying drawings.
[0021] Please refer to the following: Figures 1-5 This utility model discloses a waste removal mechanism for a die-cutting machine, comprising: a die-cutting machine body 1, with first fixing plates 2 symmetrically arranged on both sides of the discharge end of the die-cutting machine body 1, a guide roller 3 connected to the first fixing plate 2 via a shaft, a fixing block 4 arranged on the outer side of the first fixing plate 2 near the end of the guide roller 3, a limit roller 5 connected to the fixing block 4 via a shaft, a screw rod 6 connected to one side of the first fixing plate 2 near the fixing block 4, an arc-shaped guide plate 7 connected through the screw rod 6, a separating plate 10 connected to one end of the arc-shaped guide plate 7 near the limit roller 5, and a separating roller 11 connected to the bottom of the separating plate 10 via a shaft.
[0022] Combination Figure 3 and Figure 5 As shown, there are several material distribution rollers 11, with equal spacing between them. The material distribution rollers 11 abut against the cutting material 14 inside the inner frame waste 15, ensuring separation of the cutting material 14 from the inner frame waste 15. The material distribution plate 10 is located at one end of the arc-shaped guide plate 7, connected to a plug 12. This facilitates the disassembly or assembly of the material distribution plate 10 and the arc-shaped guide plate 7, allowing for the replacement of different models of material distribution plates 10 according to processing requirements. The plug 12 is inserted into the arc-shaped guide plate 7 and fixed with screws. The guide rollers 3 and the arc-shaped guide plate 7... A material belt 13 runs through the guide plates 7. Cutting material 14 and inner frame waste material 15 are bonded to the surface of the material belt 13. The material distribution roller 11 matches the cutting material 14. The spacing between several material distribution rollers 11 matches the inner frame waste material 15. A screw rod 6 is located between the arc-shaped guide plate 7 and the first fixed plate 2 and a spring 8 is sleeved on it. The screw rod 6 passes through the arc-shaped guide plate 7 and is threaded to one end with a nut 9. The spacing between the arc-shaped guide plate 7 and the guide roller 3 can be adjusted by tightening or loosening the nut 9 on the screw rod 6, which facilitates material feeding and bonding and guiding of materials of different thicknesses.
[0023] The die-cutting machine body 1 is located above the first fixed plate 2 and is symmetrically fixed to two sides with second fixed plates 16. A waste material winding motor 17 is fixedly installed on the outer side of one end of the second fixed plate 16. The output end of the waste material winding motor 17 passes through the second fixed plate 16 and is connected to a first winding roller 18. The first winding roller 18 winds the inner frame waste material 15. The die-cutting machine body 1 is located below the first fixed plate 2 and is fixedly connected to one side with a third fixed plate 19. A finished product winding motor 20 is fixedly installed on the outer side of one end of the third fixed plate 19. The output end of the finished product winding motor 20 passes through the third fixed plate 19 and is connected to a second winding roller 21.
[0024] Specifically, in use of this utility model, firstly, after die-cutting in the main body 1 of the die-cutting machine, the cutting material 14 and the inner frame waste material 15 on the strip 13 are cut off and pass around the guide roller 3 between the arc-shaped guide plate 7 and the guide roller 3. Then, the inner frame waste material 15 is wound upward from the bottom of the limiting roller 5 onto the first take-up roller 18, so that the strip 13 together with the cutting material 14 is wound onto the second take-up roller 21. Subsequently, the first take-up roller 18 is rotated by the waste material take-up motor 17, and the second take-up roller is rotated by the finished product take-up motor 20. 21 rotates, and when the material belt 13 is discharged from between the guide roller 3 and the arc-shaped guide plate 7, the cut material 14 on the material belt 13 is always adhered and limited by the arc-shaped guide plate 7 and the separating roller 11, thereby effectively preventing the cut material 14 from lifting off the material belt 13. When the inner frame waste 15 moves to the separating roller 11, the inner frame waste 15 will be dragged and directly separated from the cut material 14 because the cut material 14 is held by the separating roller 11, thereby preventing the inner frame waste 15 from being lifted off the material belt 13 along with the cut material 14.
[0025] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
