DETAILED DESCRIPTION

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The X-axis direction is the left-right direction, the Y-axis direction is the front-back direction, and the Z-axis direction is the up-down direction.

[0021] The double-station die-cutting device of the die-cutting machine includes a frame 1, a die-cutting knife group 2 and a die-cutting traction assembly 4; the frame 1 has a first die-cutting station and a second die-cutting station; the coil release station is arranged in front of the first die-cutting station and the second die-cutting station, and the die-cutting traction assembly 4 has two groups, including a first die-cutting traction assembly and a second die-cutting traction assembly, which are respectively arranged in the first die-cutting station and the second die-cutting station, and the two groups of paper feeding traction components move the material left and right, and the die-cutting knife group 2 is connected to the horizontal driving mechanism driving it to move left and right.

[0022] The die-cutting knife group 2 includes a plurality of die-cutting knives and a slide. The number of die-cutting knives matches the number of (a row of) graphics in the Y-axis direction of the material. The slide is provided with a guide rail. The die-cutting knives are adjusted forward and backward on the guide rail. The distance between the die-cutting knives is adjusted according to the spacing of the graphics to be die-cut. The slide is connected to a motor that drives it to move forward and backward. The die-cutting knife group 2 is a prior art. The die-cutting knife group 2 has two groups (a first die-cutting knife component and a second die-cutting knife component), which are respectively arranged at the first die-cutting station and the second die-cutting station. The material to be die-cut enters the die-cutting knife group 2 of the first die-cutting station and the second die-cutting station in turn, and the material is die-cut at the same time. The material has multiple lines of graphics. The die-cutting knife group 2 on the first die-cutting station performs die-cutting on the nth line of graphics of the material, and the die-cutting knife group 2 on the second die-cutting station performs die-cutting on the n+1th line of graphics of the material. The two groups of die-cutting knife groups 2 cooperate to die-cut the material, thereby improving efficiency. The die-cutting traction component 4 is arranged below the die-cutting knife group 2, and the die-cutting traction component 4 includes a paper pulling roller 41 and a paper clamping roller 42, and the paper pulling roller 41 and the paper clamping roller 42 are arranged opposite to each other on the left and right; the paper pulling roller 41 is connected to the first rotating drive component in transmission connection, and the paper clamping roller 42 is connected to the telescopic driving component that drives it to move left and right, and the telescopic driving component drives the paper clamping roller 42 away from or close to the paper pulling roller 41. When the paper clamping roller 42 is away from the paper pulling roller 41, the gap between the paper clamping roller 42 and the paper pulling roller 41 increases, which is convenient for material to enter. During operation, the paper clamping roller 42 approaches the paper pulling roller 41, and the gap between the paper clamping roller 42 and the paper pulling roller 41 decreases. The first rotating drive component drives the paper pulling roller 41 to rotate in both directions, so that the material moves back and forth along the X-axis at the first time to ensure the accuracy of die cutting. When the paper pulling roller 41 rotates forward, the paper clamping roller 42 cooperates with the paper pulling roller 41 to drive the material forward. When the paper pulling roller 41 rotates reversely, the paper clamping roller 42 cooperates with the paper pulling roller 41 to drive the material backward. The transverse driving mechanism drives the die-cutting knife group 2 to move in both directions along the Y axis, and the material is driven by the traction roller 31 to move in both directions along the X axis, so that the die-cutting knife group 2 can adapt to graphics of different shapes, especially special-shaped graphics.

[0023] In order to ensure the cutting accuracy of the material, the material is supported to prevent the material from being deformed during cutting. A support plate 5 is provided on one side of the paper pulling roller 41, and the support plate 5 is used to support the material cut by the die cutting knife group 2.

[0024] In order to ensure the quality of lamination, the feeding end of the first die-cutting station and the discharging end of the second die-cutting station are respectively provided with a lamination assembly 3. In this embodiment, the lamination assembly 3 is respectively arranged on the left and right sides of the frame 1, wherein the lamination assembly 3 includes a traction roller 31 and a paper pressing roller 32, wherein the traction roller 31 and the paper pressing roller 32 are arranged opposite to each other up and down, and the paper pressing roller 32 is arranged above the traction roller 31, and the traction roller 31 is connected to the second rotating driving component driving it to rotate, and the paper pressing roller 32 is connected to the lifting driving component driving the up and down movement, and the lifting driving component drives the paper pressing roller 32 to rise, so as to facilitate the material to enter between the paper pressing roller 32 and the traction roller 31. After the assembly is completed, the lifting driving component drives the paper pressing roller 32 to move downward to cooperate with the lamination.

[0025] In order to ensure the tension balance of the material during the process of the material moving forward or backward, a material storage lifting roller 6 is provided below the die-cutting knife group 2, and a vertical guide rail is provided on the frame 1. The material storage lifting roller 6 is slidably set on the vertical guide rail, and the material storage lifting roller 6 is rotatably set on the mounting seat, and the mounting seat slides up and down on the vertical guide rail. When the material moves forward, the material storage lifting roller 6 is lifted in coordination, and when the material moves backward, the material storage lifting roller 6 is lowered accordingly due to the influence of gravity, ensuring that the tension of the material during the processing process is highly stable.

[0026] The working principle of the utility model is described below in conjunction with the accompanying drawings: when adjusting the machine, the paper pressing roller 32 is away from the traction roller 31, and the paper clamping roller 42 is away from the paper pulling roller 41, so that the material passes through the first film-covering assembly 3, the first die-cutting traction assembly, the first die-cutting tool, the material storage lifting roller 6, the second die-cutting traction assembly, the second die-cutting tool and the second film-covering assembly 3. The first die-cutting traction assembly and the second die-cutting traction assembly cooperate to make the material move forward or backward.

[0027] During die-cutting operation, the die-cutting traction assembly 4 moves the material bidirectionally along the X-axis, and the lateral drive mechanism drives the die-cutting tool to move bidirectionally along the Y-axis to die-cut various different graphics on the support plate 5. The die-cutting knife group 2 on the first die-cutting station die-cuts the nth row of the material, and the die-cutting knife group 2 on the second die-cutting station die-cuts the n+1th row of the material. The two groups of die-cutting knife groups 2 work simultaneously to improve work efficiency. When the material moves forward, the storage lifting roller 6 is lifted in cooperation. When the material moves backward, the storage lifting roller 6 is affected by gravity, and the storage lifting roller 6 drops accordingly to ensure that the tension of the material during the processing is stable.
