[0036] The following is combined with Figures 1-8 This application is described in further detail.

[0037] The embodiment of the present application discloses a high-efficiency die-cutting device. Figure 1 and Figure 2The high-efficiency die-cutting device includes a die-cutting system 1, which includes a mounting platform 11, an upper die base 12, a lower die base 13, a cutter die 14 and a hydraulic cylinder 15. The hydraulic cylinder 15 is fixedly arranged on the mounting platform 11, the upper die base 12 is fixed on the piston rod of the hydraulic cylinder 15, the cutter die 14 is arranged on the upper die base 12, and the lower die base 13 is arranged on the mounting platform 11; when die-cutting the material, the material is pulled to the top of the sliding seat 132, and the hydraulic cylinder 15 is started. The hydraulic cylinder 15 drives the upper die group and the cutter die 14 to move toward the material to die-cut the material. While the upper die base 12 descends, under the action of the first driving member 2, the sliding seat 132 is driven to move upward. The upward movement of the sliding seat 132 drives the material to move toward the upper die base 12 so that the cutter die 14 contacts the material for die-cutting.

[0038] Reference Figure 1 and Figure 2 In order to improve the die-cutting efficiency of the material, the lower die base 13 includes a rectangular frame 131 fixedly set on the mounting table 11 and a sliding seat 132 set in the rectangular frame 131. The sliding seat 132 is slidably set in the rectangular frame 131. The sliding direction of the sliding seat 132 is parallel to the sliding direction of the upper die base 12. The initial position of the sliding seat 132 is flush with the surface of the mounting table 11. The sliding seat 132 is used to receive the material to be die-cut. The mounting table 11 is provided with a first driving member 2. The first driving member 2 is used to As the die base 12 moves downward, it simultaneously drives the slide base 132 upward, shortening the stroke of the upper die base 12. As the upper die base 12 moves toward the lower die base 13, the first drive member 2 drives the slide base 132 upward, allowing the cutter die 14 to contact the material and perform die-cutting. When the die-cutting material has two cutter dies 14, A and B are fixed to the upper die base 12 and the slide base 132, respectively. Furthermore, a corresponding cutter pad is provided on the slide base 132 to extend the service life of the cutter die 14. Furthermore, as the slide base 132 moves upward, the stroke of the piston rod of the hydraulic cylinder 15 is adjusted, so that after the cutter die 14 has die-cut the material, the piston rod of the hydraulic cylinder 15 immediately returns, allowing the next die-cutting process to proceed.

[0039] Reference Figure 1 and Figure 2In the embodiment of the present application, the first driving member 2 includes a driving rod 21, a connecting rod 22, a wedge block 23 and a wedge-shaped inclined surface 24. The driving rod 21 is fixedly arranged at the bottom of the upper mold base 12. The length direction of the driving rod 21 is perpendicular to the bottom wall of the upper mold base 12 and perpendicular to the top surface of the mounting platform 11. The driving rod 21 is slidably arranged in the mounting platform 11. The driving rod 21 slides in a direction perpendicular to the top surface of the mounting platform 11. The connecting rod 22 is slidably arranged in the mounting platform 11 and is perpendicular to the driving rod 21. The mounting platform 11 is provided with a mounting groove 3. The area of ​​the seat 12 is smaller than the opening area of ​​the mounting groove 3. The lower mold seat 13 is arranged in the mounting groove 3. The wedge block 23 is slidably arranged in the mounting groove 3 and fixedly arranged on the connecting rod 22. The side surface of the wedge block 23 is inclined in the direction away from the bottom of the mounting groove 3. The wedge-shaped inclined surface 24 is opened on the side wall of the sliding seat 132 and is adapted to the wedge block 23. The first driving member 2 also includes a transmission member, which is used to drive the rod 21 to slide and push the connecting rod 22 to move. The movement of the connecting rod 22 pushes the wedge block 23 to move and drives the sliding seat 132 to move.

[0040] When the upper die base 12 moves driven by the hydraulic cylinder 15, the upper die base 12 drives the driving rod 21 to move toward the inside of the mounting platform 11. At this time, under the action of the transmission part, the connecting rod 22 is pushed to move, and the connecting rod 22 moves to push the wedge block 23 to move. The wedge block 23 moves to lift the sliding seat 132, and the sliding seat 132 lifts the material to perform die cutting. The operation is simple and convenient.

[0041] Reference Figure 2 and Figure 3 When the upper die seat 12 moves up and returns, in order to facilitate the sliding seat 132 to move down and return to its initial position, a positioning rod 4 is fixedly provided at the bottom of the sliding seat 132. The positioning rod 4 is perpendicular to the bottom wall of the mounting groove 3. The mounting platform 11 is located at the bottom wall of the mounting groove 3 and is provided with a positioning groove 5 for the sliding insertion of the positioning rod 4. The positioning rod 4 is sleeved with a second spring 6. The second spring 6 drives the sliding seat 132 to have a sliding tendency toward the deep end of the mounting groove 3 so that the side of the sliding seat 132 is pressed against the wedge block 23. Under the action of the positioning rod 4 and the positioning groove 5, the sliding direction of the sliding seat 132 is limited, so that The sliding seat 132 only moves in the vertical direction, which facilitates the die-cutting of the material; under the action of the second spring 6, the upper die seat 12 pulls the sliding seat 132 down when returning, and ensures that the sliding seat 132 is pressed against the wedge block 23 to facilitate the die-cutting of the next procedure; at the same time, under the action of the second spring 6, the sliding seat 132 is pressed against the wedge block 23, so that the sliding seat 132 and the wedge block 23 are always in contact, thereby reducing the possibility of the wedge block 23 impacting the sliding seat 132, reducing the possibility of damage to the wedge block 23 and the sliding seat 132, and reducing the generation of noise during the processing.

[0042] Reference Figure 2In the embodiment of the present application, the transmission member includes a rack 25, a gear 26, a cam 27 and a first spring 28. The rack 25 is fixedly arranged on the driving rod 21 and is parallel to the driving rod 21. The gear 26 is rotatably arranged in the mounting platform 11 and meshes with the rack 25. The cam 27 is coaxially arranged on the gear 26. The end of the connecting rod 22 abuts the peripheral wall of the cam 27. The first spring 28 is arranged in the mounting platform 11 and one end is fixedly arranged on the connecting rod 22. The first spring 28 drives the connecting rod 22 to have a sliding tendency toward the direction of the cam 27 so that the connecting rod 22 abuts the peripheral wall of the cam 27.

[0043] When the upper mold base 12 moves, the upper mold base 12 drives the driving rod 21 and the rack 25 to move, the rack 25 moves and drives the gear 26 to rotate, the gear 26 rotates and drives the cam 27 to rotate synchronously, the cam 27 rotates and drives the connecting rod 22 to move, the connecting rod 22 moves and drives the wedge block 23 and the sliding seat 132 to move, the operation is simple and convenient; under the action of the first spring 28, the connecting rod 22 is driven to fit the peripheral wall of the cam 27, which makes it easier for the cam 27 to drive the connecting rod 22 to move; at the same time, in this process, the transmission noise is reduced and the impact of the driving rod 21 on the connecting rod 22 is reduced.

[0044] Reference Figure 4 and Figure 5 In an embodiment of the present application, the die-cutting device also includes an adjusting member 7, which is used to make the material on the mounting table 11 parallel to the sliding seat 132 when the sliding seat 132 lifts the material; after the sliding seat 132 lifts the material, the material is leveled to reduce the possibility of material wrinkles, thereby improving the die-cutting effect of the material.

[0045] Reference Figure 4 and Figure 5In the embodiment of the present application, the adjusting member 7 includes a lower pressing roller 71 provided on the rectangular frame 131. Two lower pressing rollers 71 are provided and are located on both sides of the sliding seat 132. The length direction of the lower pressing roller 71 is parallel to the width direction of the material. After the material passes between the rectangular frame 131 and the lower pressing roller 71, it enters the upper part of the sliding seat 132. The lower pressing roller 71 is rotatably provided on the rectangular frame 131. The rotation direction of the lower pressing roller 71 is opposite to the material conveying direction. When the material is lifted by the sliding seat 132, the lower pressing roller 71 rotates to apply a pulling force opposite to the conveying direction to the material, thereby causing the die-cutting part of the material to be pressed. The material is flatly laid on the sliding seat 132. The rotation speed of the lower pressure roller 71 is slower than that of the material conveying roller. The material conveying roller reels the material and drives it forward. When the sliding seat 132 lifts the material, there is a possibility of excess material being fed in front of the sliding seat 132, resulting in a large amount of material above the sliding seat 132. At this time, the lower pressure roller 71 rotates. Because the rotation direction of the lower pressure roller 71 is opposite to the direction of material travel, when the sliding seat 132 is lifted, it pulls the material in the opposite direction, causing the material to be laid flat on the sliding seat 132, thereby improving the material die-cutting effect. At the same time, when the material is lifted, the lower pressure rollers 71 on both sides apply a pulling force parallel to the conveying direction and toward both sides to the material, causing the material to tend to be stretched. During the stretching process, the die-cutting marks of the material are deformed, facilitating the subsequent waste removal operation.

[0046] Reference Figure 4 When the sliding seat 132 lifts the material, the edge of the material is pressed against the corner of the sliding seat 132, which can easily cause damage to the material. Therefore, in the embodiment of the present application, a rounded corner 8 is provided on the side of the sliding seat 132 so that the material fits on the rounded corner 8 when the sliding seat 132 lifts the material; the material is in a taut state due to the lifting of the sliding seat 132 and fits on the rounded corner 8 of the sliding seat 132, thereby reducing the possibility of the material being damaged.

[0047] Reference Figure 4 and Figure 5, when the deformation of the die-cutting material is small, the material is difficult to deform during the lifting process of the sliding seat 132, or the deformation of the material is easily damaged. Under this background, in order to facilitate the die-cutting operation of the material, in the embodiment of the present application, a mounting frame 72 is provided on the rectangular frame 131, and the lower pressure roller 71 is rotatably arranged in the mounting frame 72, and a driving motor 73 for driving the lower pressure roller 71 to rotate is provided on the mounting frame 72; a receiving roller 74 is provided in the mounting frame 72 and below the lower pressure roller 71, and the receiving roller 74 is parallel to the lower pressure roller 71, and the material passes between the receiving roller 74 and the lower pressure roller 71 and enters the top of the sliding seat 132, and the mounting frame 72 is slidably set on the rectangular frame 131 , the mounting frame 72 slides vertically; when the deformation of the die-cutting material is small or the amount of stretching is small, the material is passed through the receiving roller 74 and the lower pressing roller 71, and then the height of the mounting frame 72 is adjusted according to the lifting height of the sliding seat 132, so that the material is consistent with the height after the sliding seat 132 is lifted, and then the die-cutting operation is carried out; under the action of the mounting frame 72, the use range of the die-cutting device is improved; at the same time, for specific materials, such as materials that are easily scratched, after the material is lifted by the mounting frame 72, the material and the sliding seat 132 are in a separated state. When the material moves forward, the possibility of contact with the sliding seat 132 is reduced, thereby reducing the possibility of scratching the material.

[0048] Reference Figure 4 、 Figure 5 and Figure 6 The second driving member 75 includes a rotating rod 75, an electric push rod 76 and a balance rod 78. One end of the rotating rod 75 is hinged to the bottom wall of the mounting frame 72, and the other end is slidably arranged in the accommodating groove 9. The electric push rod 76 is arranged in the accommodating groove 9 and the rotating rod 75 is fixedly arranged on the output shaft of the electric push rod 76. There are two electric push rods 76 and they are opposite to each other. The balance rod 78 is fixedly arranged at the bottom of the mounting frame 72 and slidably penetrates the rectangular frame 131. When the height of the receiving roller 74 and the lower pressure roller 71 is adjusted, the electric push rod 76 is started, and the electric push rod 76 pushes the rotating rod 75 to slide in the accommodating groove 9. The rotating rod 75 rotates during the sliding process, thereby adjusting the height of the mounting frame 72. The operation is simple and convenient. Under the action of the balance bar 78, the mounting frame 72 is kept in a horizontal state, which reduces the possibility of the receiving roller 74 and the lower pressure roller 71 tilting.

[0049] Reference Figure 7Furthermore, after the height of the mounting frame 72 is adjusted, in order to ensure that the mounting frames 72 on both sides of the sliding seat 132 are at the same height, a laser pen 10 is provided on one of the mounting frames 72, and an identification frame 16 is provided on the other mounting frame and located opposite the laser pen 10. The identification frame 16 includes two mutually perpendicular identification rods, and the laser emitted by the laser pen 10 is facing the intersection of the identification rods; through the cooperation of the laser pen 10 and the identification rods, the adjusted heights of the mounting frames 72 on both sides are compared, and then corresponding adjustments are made, so that the mounting frames 72 on both sides are flush, thereby improving the die-cutting effect of subsequent materials.

[0050] Reference Figure 4 and Figure 5 In the embodiment of the present application, the receiving roller 74 is slidably set in the mounting frame 72, and the receiving roller 74 slides vertically along the mounting frame 72. The receiving roller 74 slides close to the lower pressure roller 71 to press the material. Slide blocks 79 are set on both sides of the receiving roller 74, and the receiving roller 74 is rotatably set on the sliders 79. The vertical side wall of the mounting frame 72 is rotatably set with an adjusting screw 710, and the slider 79 is threadedly connected to the adjusting screw 710; the position of the slider 79 on the adjusting screw 710 is adjusted by rotating the adjusting screw 710, and the distance between the receiving roller 74 and the lower pressure roller 71 is adjusted to facilitate the pressing of the material.

[0051] The implementation principle of a high-efficiency die-cutting device in the embodiment of the present application is as follows:

[0052] When die-cutting materials with good toughness and good elongation, the materials are passed between the receiving roller 74 and the lower pressing roller 71. At this time, the receiving roller 74 is located below the receiving groove 9, and the bottom of the lower pressing roller 71 is flush with the mounting platform 11. Then the hydraulic cylinder 15 is started, and the hydraulic cylinder 15 drives the upper die base 12 to move toward the lower die base 13. The upper die base 12 drives the driving rod 21 to move toward the inside of the mounting platform 11. The driving rod 21 and the rack 25 move synchronously. The rack 25 moves and drives the gear 26 to rotate, and the gear 26 rotates. The movement drives the cam 27 to rotate synchronously, and the rotation of the cam 27 drives the connecting rod 22 to move. The movement of the connecting rod 22 drives the wedge block 23 and the sliding seat 132 to move. The sliding seat 132 is lifted out of the mounting table 11 and drives the material to be lifted, thereby reducing the running stroke of the upper die seat 12 and thus improving the die-cutting efficiency of the material; when the upper die seat 12 returns, under the action of the first spring 28 and the second spring 6, the sliding seat 132 and the connecting rod 22 return to their initial positions and prepare for the next die-cutting operation.

[0053] When die-cutting materials with higher hardness and relatively normal elongation, the electric push rod 76 is first started, and the electric push rod 76 pushes the rotating rod 75 to slide in the receiving groove 9. The rotating rod 75 rotates during the sliding process, thereby adjusting the height of the mounting frame 72, and thus adjusting the height of the lower pressing roller 71 and the receiving roller 74, so that the space between the lower pressing roller 71 and the receiving roller 74 is located at the maximum stroke of the sliding seat 132, and the material is clamped between the receiving roller 74 and the lower pressing roller 71 and flush with the sliding seat 132, and then the hydraulic cylinder 15 is started, and the hydraulic cylinder 15 drives the lower pressing roller 71 to move upward. The movable upper die base 12 moves toward the lower die base 13, and the upper die base 12 drives the driving rod 21 to move toward the inside of the mounting platform 11. The driving rod 21 and the rack 25 move synchronously. The rack 25 moves and drives the gear 26 to rotate. The rotation of the gear 26 drives the cam 27 to rotate synchronously. The rotation of the cam 27 drives the connecting rod 22 to move. The movement of the connecting rod 22 drives the wedge block 23 and the sliding seat 132 to move. The sliding seat 132 is lifted out of the mounting platform 11 and drives the material to be lifted, thereby reducing the operating stroke of the upper die base 12 and improving the die-cutting efficiency of the material.

[0055] The implementation principle of a die-cutting flat knife machine in the embodiment of the present application is as follows:
