Description

Technical Field

[0001] The invention relates to the technical field of die cutting machines, in particular to a die cutting machine with adjustable cutting blade angle. Background Art

[0002] In the die-cutting industry, traditional die-cutting machines generally rely on a cutter fixed on a die-cutting drum to perform cutting tasks, and the rotation of the drum drives the cutter to cut various materials. However, this fixed cutter configuration exposes technical limitations in certain application scenarios. Specifically, since the cutter is fixed on the die-cutting drum, the angle of the cutter relative to the die-cutting drum remains unchanged during the entire cutting process. For thin or medium-thick materials, this design may still meet basic cutting needs, but when facing thick materials, the pressure applied by the cutter to the upper side of the material increases significantly as the drum rotates after the cutter cuts into the thick material. The upper part of the material is subjected to excessive side extrusion pressure, which not only causes uneven cutting edges, but may also cause deformation of the material itself, thereby affecting the functional integrity and appearance of the product, and ultimately causing a decline in the qualified rate of finished products. Summary of the invention

[0003] In view of the above-mentioned prior art, the present invention provides a die-cutting machine with adjustable cutting blade angle to solve the above-mentioned technical problems.

[0004] To achieve the above object, the technical solution of the embodiment of the present invention is implemented as follows:

[0005] A die-cutting machine with adjustable cutter angle comprises a die-cutting roller, a fixed platform, a swinging platform, a first base, a second base, a first drive assembly and a second drive assembly, wherein the first base and the second base are arranged on the fixed platform, the die-cutting roller is provided with a cutter, the die-cutting roller is rotatably connected to the swinging platform, the swinging platform is provided with rotating wheels on both sides of the bottom, the first base is provided with a guide rail, the rotating wheel rolls along the guide rail, the swinging platform is provided with a sliding slider, the slider is rotatably connected to a swing arm, the swing arm is rotatably connected to the second base, the first drive assembly drives the swing arm to swing back and forth, and the second drive assembly drives the die-cutting roller to rotate.

[0006] Furthermore, the guide rail includes a first arc portion, a second arc portion, a straight portion, a third arc portion and a fourth arc portion which are tangent to each other in sequence, the straight portion is located at the bottom of the guide rail, the second arc portion and the third arc portion are respectively located on the left and right sides of the straight portion, the first arc portion and the third arc portion are concentric, and the center of the third arc portion is tangent to the outer contour of the cutter, the second arc portion and the fourth arc portion are concentric, and the circle of the second arc portion is tangent to the outer contour of the cutter, and when the connecting line of the rotating wheels is in a horizontal state, the center of the rotating wheel on the left side coincides with the center of the second arc portion, and the center of the rotating wheel on the right side coincides with the center of the third arc portion.

[0007] Furthermore, the cutter includes a first blade and a second blade, the first blade is parallel to the axial direction of the die-cutting roller, the second blade is arc-shaped and parallel to the circumference of the die-cutting roller, and the two sides of the two first cutters are respectively connected by the second cutters.

[0008] Furthermore, the first driving mechanism and the second driving mechanism are servo motors.

[0009] Furthermore, a feeding device is provided at both ends of the fixed platform, and the feeding device includes an upper roller, a lower roller and a third motor. The conveyed material is clamped between the upper roller and the lower roller, and the third motor is used to drive the upper roller and the lower roller to rotate.

[0010] Furthermore, the third motor is a servo motor.

[0011] Furthermore, support legs are provided at the bottom of the fixed platform.

[0012] Furthermore, the support legs are connected by a cross bar.

[0013] The beneficial effect of the present invention is that since the angle of the cutter can be adjusted during the cutting process, the extrusion of the material is reduced, so the die-cutting machine can cut materials of greater thickness, broadening its application range. The first drive component drives the swing table to rotate around the roller, so that the cutter can reduce the extrusion of the left and right sides of the material to be cut during the cutting process, thereby improving the cutting accuracy, especially when processing thicker materials. The present invention prevents the die-cutting process from causing product function failure or appearance defects, thereby further improving the finished product yield. The cutter on the die-cutting roller is used for continuous roller cutting, which can maintain high cutting efficiency and is suitable for large-scale, continuous production tasks.

[0025] Please refer to the attached Figures 1 to 7The present application provides a die-cutting machine with adjustable cutter angle, comprising a die-cutting roller 1, a fixed platform 2, a swinging platform 3, a first base 4, a second base 5, a first drive assembly 6 and a second drive assembly 7. The fixed platform 2 is provided with the first base 4 and the second base 5, the die-cutting roller 1 is provided with a cutter 8, the die-cutting roller 1 is rotatably connected to the swinging platform 3, the swinging platform 3 is provided with rotating wheels 9 on both sides of the bottom, the first base 4 is provided with a guide rail 10, the rotating wheel 9 rolls along the guide rail 10, the swinging platform 3 is provided with a sliding slider 11, the slider 11 is rotatably connected to a swing arm 12, the swing arm 12 is rotatably connected to the second base 5, the first drive assembly 6 drives the swing arm 12 to swing back and forth, and the second drive assembly 7 drives the die-cutting roller 1 to rotate. The material to be cut is placed on the fixed platform 2, and the material to be cut can be driven by a feeding mechanism, or the force of the die-cutting roller 1 rotating can be used to drive the material to be cut. The die-cutting cylinder 1 is provided with a cutter 8. When the die-cutting cylinder 1 rotates toward the material to be cut, the cutter 8 gradually cuts into the material to be cut, thereby cutting the material to be cut into a desired shape. The die-cutting cylinder 1 is set on the swing table 3, and the second drive assembly 7 is used to drive the film cutting assembly to rotate. While the die-cutting cylinder 1 rotates, the second drive assembly 7 is used to drive the swing table 3 to rotate, and the swing table 3 drives the second base 5 to swing back and forth around two centers of the circle, so that the die-cutting cylinder 1 performs a combined motion of self-rotation and double circular swinging motion. Specifically, the swing arm 12 is connected to the first driving assembly 6, and the first driving assembly 6 drives the swing arm 12 to swing back and forth, and the swing arm 12 is rotationally connected to the second base 5 and slidably connected to the swing table 3. The swing arm 12 can slide up and down relative to the swing table 3. When the swing arm 12 rotates to the right, it drives the swing table 3 to slide and rotate to the right. Therefore, the swing table 3 swings to the right with the roller on the right side of the bottom as the center. During the swinging process, the roller on the right side of the bottom is attached to the right side of the bottom of the guide rail 10. When the swing arm 12 is reset to the middle position from the middle to the right side, the swing table 3 swings to the left with the roller on the right side of the bottom as the center. During the swinging process, the roller on the right side of the bottom is still attached to the right side of the bottom of the guide rail 10, thereby realizing that the die-cutting roller 1 completes its rotation and reciprocating swings with the right roller as the center. When the swing arm 12 rotates from the middle to the left, the swing table 3 is driven to slide and rotate to the left. Therefore, the swing table 3 swings to the left with the roller on the left bottom as the center. During the swinging process, the roller on the left bottom is attached to the left side of the bottom of the track. When the swing arm 12 is reset to the middle position from the left, the swing table 3 swings to the right with the roller on the left bottom as the center. During the swinging process, the roller on the left bottom is still attached to the left side of the bottom of the track, thereby realizing that the die-cutting roller 1 completes its rotation and reciprocating swings with the right roller as the center.

[0026] The material to be cut moves from the right to the left, and when it enters between the die-cutting roller 1 and the fixed platform 2, the cutter 8 rotates with the die-cutting roller 1 to the material to be cut, and the cutter 8 cuts the material to be cut, and cuts the rectangular outline of the material to be cut. When the cutter 8 of the prior art contacts the material to be cut, the cutter 8 first cuts into the upper part of the material to be cut, and as the depth of the cut increases, the cutter 8 gradually squeezes the upper material on the left side of the material to be cut. However, before or during cutting, the present invention uses the first drive component 6 to drive the swing table 3 to rotate around the roller on the right side, so that the cutter 8 swings a short distance to the right, thereby reducing the extrusion of the cutter 8 on the upper left material of the material to be cut. As the cutter 8 gradually rotates and cuts deeper, the angle of the cutter 8 can be gradually adjusted to make it perpendicular to the material to be cut. After swinging to the right, as the cutter 8 rotates, the first drive assembly 6 also gradually drives the swing table 3 to swing to the left around the roller on the right, so that the die-cutting roller 1 gradually swings to the left and resets. Before the cutter 8 rotates to the bottom, the die-cutting roller 1 swings to the left and resets, ensuring that the cutter 8 can cut to the bottom of the material to be cut. Similarly, in the process of the cutter 8 swinging to the left from the bottom, the first drive assembly 6 drives the swing table 3 to rotate around the roller on the left, so that the cutter 8 swings to the left a short distance, thereby reducing the cutter 8 from squeezing the material on the right side of the upper part of the material to be cut. As the cutter 8 gradually rotates and rises, after the cutter 8 is separated from the material to be cut, the first drive assembly 6 drives the swing table 3 to swing to the right around the roller on the left, driving the die-cutting roller 1 to reset.

[0027] like Figures 6-7 As shown, Figure 6 The dotted arrow in the figure is the trajectory of the swing. Figure 7 As shown, the dotted line in the figure is the rotation trajectory of the die-cutting roller 1 in the prior art, and the solid line is the rotation trajectory of the die-cutting roller 1 of the present invention. The horizontal direction at the bottom is the material to be cut. When the present invention is die-cutting the material to be cut, the extrusion of the material on the left and right sides of the cutter 8 can be reduced, and the material of a larger thickness can be cut to improve the cutting accuracy. The cutter 8 on the die-cutting roller 1 is used to cut the material to be cut, and continuous roller cutting can be performed to improve the cutting efficiency.

[0028] Specifically, the guide rail 10 includes a first arc portion 13, a second arc portion 14, a straight portion 15, a third arc portion 16 and a fourth arc portion 17 which are tangent to each other in sequence, the straight portion 15 is located at the bottom of the guide rail 10, the second arc portion 14 and the third arc portion 16 are respectively located on the left and right sides of the straight portion 15, the first arc portion 13 and the third arc portion 16 are concentric, and the center of the third arc portion 16 is tangent to the outer contour of the cutter 8, the second arc portion 14 and the fourth arc portion 17 are concentric, and the circle of the second arc portion 14 is tangent to the outer contour of the cutter 8, and when the connecting line of the rotating wheel 9 is in a horizontal state, the center of the rotating wheel 9 on the left side coincides with the center of the second arc portion 14, and the center of the rotating wheel 9 on the right side coincides with the center of the third arc portion 16. The distance between the center of the second arc portion 14 and the center of the third arc portion 16 is equal to the distance between the rotation centers of the two rollers. The swing table 3 is located in the middle of the guide rail 10 in the initial state. In the initial state, the roller on the left is in contact with the second arc portion 14, and the roller on the right is in contact with the third roller. When the swing arm 12 rotates from the middle to the right, it pushes the swing table 3 to rotate right. During the rotation, the swing table 3 rotates right with the roller on the right as the axis, and the roller on the left is lifted and rolls upward along the first arc portion 13, so that the die-cutting roller 1 swings to the right. When the swing arm 12 rotates from the right to the left toward the center, it pushes the swing table 3 to rotate left, and the roller on the left rolls downward along the first arc portion 13. The swing table 3 rotates left with the roller on the right as the axis, so that the die-cutting roller 1 swings to the left and resets. Similarly, when the swing arm 12 rotates from the middle to the left, the swing table 3 rotates to the left. During the rotation, the swing table 3 rotates to the left with the roller on the left as the axis, and the roller on the right is lifted and rolls along the second arc portion 14, so that the die-cutting cylinder 1 swings to the left. When the swing arm 12 rotates from the left to the right toward the center, it pushes the swing table 3 to rotate to the right, and the roller on the right rolls downward along the third arc portion 16. The swing table 3 rotates to the right with the roller on the left as the axis, so that the die-cutting cylinder 1 swings to the right and resets.

[0029] Specifically, the cutter 8 includes a first blade 18 and a second blade 19, wherein the first blade 18 is parallel to the axial direction of the die-cutting roller 1, and the second blade 19 is arc-shaped and parallel to the circumference of the die-cutting roller 1, and the two sides of the two first cutters 8 are connected by the second cutters 8 respectively. The cutter 8 includes two first blades 18 and two second blades 19, and the plane where the second blades 19 are located is perpendicular to the axial direction of the die-cutting roller 1. The first cutter 8 and the second cutter 8 are used to cut the material to be cut into a rectangular shape. When die-cutting, the first cutter 8 and the second cutter 8 rotate to cut the material to be cut, and the angle between the first cutter 8 and the die-cutting piece changes continuously with the rotation, while the angle between the second cutter 8 and the material to be cut remains unchanged during the rotation. The first cutter 8 and the second cutter 8 are connected in sequence to form a closed structure, which can cut the material into a regular rectangle.

[0030] Specifically, the first drive mechanism and the second drive mechanism are servo motors. The servo motors are used to accurately control the rotation of the swing arm 12 and the die-cutting cylinder 1. Preferably, in order to keep the two sides of the die-cutting cylinder 1 balanced, the first drive mechanism and the second drive mechanism can be set on one side of the die-cutting cylinder 1, and a counterweight can be set on the other side, or the first drive mechanism and the second drive mechanism can be set on both sides of the die-cutting cylinder 1.

[0031] Specifically, a feeding device 21 is provided at both ends of the fixed platform 2, and the feeding device 21 includes an upper roller 22, a lower roller 23 and a third motor 24. The conveyed material is clamped between the upper roller and the lower roller 23, and the third motor 24 is used to drive the upper roller 22 and the lower roller 23 to rotate. The feeding device 21 is used to assist in the cutting of the material to be cut and improve the stability of material transportation. When working, the motor drives the upper roller 22 and the lower roller 23 to rotate, thereby driving the material to be transported.

[0032] Specifically, the third motor 24 is a servo motor, which can accurately control the conveying of materials.

[0033] Specifically, the bottom of the fixed platform 2 is provided with support legs 25, and the support legs 25 are connected by a cross bar 26. The stability of the fixed platform 2 is improved.
