Description

Technical Field

[0001] The present application relates to the technical field of die-cutting machines, and in particular, to a high-efficiency die-cutting device and a full-automatic die-cutting flat-bed machine. Background Art

[0002] A die-cutting machine, also known as a beer machine, a cutting machine, or a numerical control stamping machine, is mainly used for die-cutting (full cut, half cut), indentation, hot stamping, lamination, and automatic waste discharging of some non-metallic materials, self-adhesive labels, EVA, double-sided tape, electronics, mobile phone gaskets, etc. The die-cutting machine uses steel knives, metal molds, steel wires (or templates engraved from steel plates), and applies a certain pressure through an impression plate to cut the printed matter or cardboard into a certain shape, which is an important device for post-printing packaging processing and forming.

[0003] A flat-bed die-cutting machine generally includes a main machine frame, a die-cutting system, a transmission system, a feeding system, and a control system, etc. The die-cutting system includes an upper die base, a lower die base, a die mold, and a hydraulic cylinder, etc. When using a single die mold, the die mold is fixed on the lower die base, and the material to be die-cut is placed between the die mold and the upper die base. Subsequently, the hydraulic cylinder is started to drive the lower die base to move for die-cutting the material; when there are two die molds, the die molds are respectively fixed on the upper die base and the lower die base, and then die-cutting is carried out.

[0004] However, the flat-bed machine adopts a descending-ascending intermittent motion mode, and the time consumption of the die mold in the non-cutting stage (idle stroke) accounts for a relatively high proportion. The reciprocating motion of the tool results in a relatively general die-cutting efficiency. Summary of the Invention

Detailed implementation manners

[0020] The following further elaborates on the present application in conjunction with the attached Figures 1 - 8 For a more detailed description of the present application.

[0021] An embodiment of the present application discloses a high-efficiency die-cutting device. Referring to Figure 1 and Figure 2 , the high-efficiency die-cutting device includes a die-cutting system 1. The die-cutting system 1 includes an installation table 11, an upper die holder 12, a lower die holder 13, a cutting die 14, and a hydraulic cylinder 15. The hydraulic cylinder 15 is fixedly arranged on the installation table 11. The upper die holder 12 is fixed on the piston rod of the hydraulic cylinder 15. The cutting die 14 is arranged on the upper die holder 12. The lower die holder 13 is arranged on the installation table 11. When die-cutting the material, the material is pulled to above the sliding seat 132, and the hydraulic cylinder 15 is started. The hydraulic cylinder 15 drives the upper die set and the cutting die 14 to move towards the material for die-cutting. While the upper die holder 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 towards the upper die holder 12, so that the cutting die 14 contacts the material for die-cutting.

[0022] Referring to Figure 1 and Figure 2, To improve the die-cutting efficiency of materials, the lower die base 13 includes a rectangular frame 131 fixedly arranged on the mounting table 11 and a sliding seat 132 arranged within the rectangular frame 131. The sliding seat 132 is slidably arranged within the rectangular frame 131, and 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 hold the materials to be die-cut. A first driving member 2 is arranged on the mounting table 11. The first driving member 2 is used to drive the sliding seat 132 to move upward while the upper die base 12 moves downward, thereby shortening the stroke of the upper die base 12; when the upper die base 12 moves towards the lower die base 13, the sliding seat 132 is driven by the first driving member 2 to move upward synchronously, so that the cutting die 14 contacts the materials for die-cutting; when there are A and B cutting dies 14 for die-cutting the materials, the A and B cutting dies 14 are respectively fixed on the upper die base 12 and the sliding seat 132; further, corresponding cutting die backing plates are arranged on the sliding seat 132 to extend the service life of the cutting die 14. Further, when the sliding seat 132 moves upward synchronously, the stroke of the piston rod of the hydraulic cylinder 15 is adjusted, so that the piston rod of the hydraulic cylinder 15 immediately returns after the cutting die 14 die-cuts the materials, and the die-cutting of the next process is carried out.

[0023] Referring to Figure 1 and Figure 2 , in 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 inclined surface 24. The driving rod 21 is fixedly arranged at the bottom of the upper die base 12. The length direction of the driving rod 21 is perpendicular to the bottom wall of the upper die base 12 and perpendicular to the top surface of the mounting table 11. The driving rod 21 is slidably arranged within the mounting table 11. The driving rod 21 slides along the direction perpendicular to the top surface of the mounting table 11. The connecting rod 22 is slidably arranged within the mounting table 11 and perpendicular to the driving rod 21. An installation groove 3 is formed on the mounting table 11. The area of the upper die base 12 is smaller than the opening area of the installation groove 3. The lower die base 13 is arranged within the installation groove 3. The wedge block 23 is slidably arranged within the installation groove 3 and fixedly arranged on the connecting rod 22. The side surface of the wedge block 23 is inclined towards the direction away from the bottom of the installation groove 3. The wedge inclined surface 24 is formed on the side wall of the sliding seat 132 and is adapted to the wedge block 23. The first driving member 2 further includes a transmission member. The transmission member is used to drive the driving rod 21 to slide and push the connecting rod 22 to move. The connecting rod 22 moves to push the wedge block 23 to move, and the wedge block 23 moves to drive the sliding seat 132 to move.

[0024] 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 towards the inside of the mounting table 11. At this time, under the action of the transmission member, the connecting rod 22 is pushed to move. 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 materials for die-cutting, and the operation is simple and convenient.

[0025] Referring to Figure 2 and Figure 3, when the upper die holder 12 moves upward and returns, to facilitate the downward movement of the sliding seat 132 back to its initial position, a positioning rod 4 is fixedly arranged at the bottom of the sliding seat 132. The positioning rod 4 is perpendicular to the bottom wall of the installation groove 3. A positioning groove 5 for the sliding insertion of the positioning rod 4 is provided on the mounting table 11 and at the bottom wall of the installation groove 3. A second spring 6 is sleeved on the positioning rod 4. The second spring 6 urges the sliding seat 132 to have a sliding tendency towards the deep part of the installation groove 3, so that the side surface 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 can only move in the vertical direction, which is convenient for die-cutting of materials; under the action of the second spring 6, when the upper die holder 12 returns, it pulls the sliding seat 132 to descend, ensuring that the sliding seat 132 is pressed against the wedge block 23, so as to facilitate die-cutting in the next process; 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, 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 at the same time reducing the generation of noise during the processing process.

[0026] Referring to Figure 2 , in 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 table 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 against the circumferential wall of the cam 27. The first spring 28 is arranged in the mounting table 11 and one end is fixedly arranged on the connecting rod 22. The first spring 28 urges the connecting rod 22 to have a sliding tendency towards the direction of the cam 27, so that the connecting rod 22 abuts against the circumferential wall of the cam 27.

[0027] When the upper die holder 12 moves, the upper die holder 12 drives the driving rod 21 and the rack 25 to move. The movement of the rack 25 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, which is simple and convenient to operate; under the action of the first spring 28, the connecting rod 22 is urged to fit against the circumferential wall of the cam 27, which is convenient for the cam 27 to drive the connecting rod 22 to move; at the same time, during this process, the generation of transmission noise is reduced and the impact of the driving rod 21 on the connecting rod 22 is alleviated.

[0028] Referring to Figure 4 and Figure 5 , in the embodiment of the present application, the die-cutting device further includes an adjusting member 7. When the adjusting member 7 jacks up the material by the sliding seat 132, the material on the mounting table 11 is made parallel to the sliding seat 132; after the sliding seat 132 jacks up the material, the material is leveled, reducing the possibility of material wrinkles, thereby improving the die-cutting effect of the material.

[0029] Referring to Figure 4 and Figure 5 In the embodiment of the present application, the adjusting member 7 includes a pressing roller 71 disposed on the rectangular frame 131. There are two pressing rollers 71 and they are located on both sides of the sliding seat 132. The length direction of the pressing roller 71 is parallel to the width direction of the material. After the material passes between the rectangular frame 131 and the pressing roller 71, it enters above the sliding seat 132. The pressing roller 71 is rotatably disposed on the rectangular frame 131, and the rotation direction of the pressing roller 71 is opposite to the material conveying direction. When the material is lifted by the sliding seat 132, the pressing roller 71 rotates to apply a pulling force opposite to the conveying direction to the material, so that the die-cut part of the material is laid flat on the sliding seat 132. The rotation speed of the pressing roller 71 is less than the rotation speed of the material conveying roller; the material conveying roller winds up the material and drives the material to move forward. When the sliding seat 132 lifts the material, there is a possibility of excessive feeding of the material in front of the sliding seat 132, resulting in more material above the sliding seat 132. At this time, the pressing roller 71 rotates. Since the rotation direction of the pressing roller 71 is opposite to the material traveling direction, when the sliding seat 132 lifts, it pulls the material in the opposite direction, making the material laid flat on the sliding seat 132, thereby improving the die-cutting effect of the material. At the same time, when the material is lifted, since the pressing rollers 71 on both sides apply a pulling force parallel to the conveying direction and towards both sides to the material, the material has a tendency to be stretched. During the stretching process of the material, the die-cut traces of the material are deformed, which is convenient for subsequent waste discharging operations.

[0030] Referring to 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 easily causes 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 when the sliding seat 132 lifts the material, the material fits on the rounded corner 8; the material is in a taut state due to being lifted by 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 by the top.

[0031] Referring to Figure 4 and Figure 5When 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. In this context, 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. 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. The receiving roller 74 is parallel to the lower pressure roller 71. The material passes between the receiving roller 74 and the lower pressure roller 71 and enters the upper part of the sliding seat 132. The mounting frame 72 is slidably arranged on the rectangular frame 131. , the mounting frame 72 slides vertically; when the deformation of the die-cutting material is small or the stretching amount is small, the material passes 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, and when the material moves forward, the possibility of contact with the sliding seat 132 is reduced, thereby reducing the possibility of scratching the material.

[0032] Reference Figure 4 , Figure 5 and Figure 6 In the embodiment of the present application, a second driving member that drives the mounting frame 72 to slide is provided on the rectangular frame 131. A receiving groove 9 is provided on the top surface of the rectangular frame 131. The mounting frame 72 is located in the receiving groove 9. The second driving member 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 receiving groove 9. The electric push rod 76 is arranged in the receiving groove 9 and the rotating rod 75 is fixedly arranged on the output shaft of the electric push rod 76. Two electric push rods 76 are provided and 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 adjusting the height of the receiving roller 74 and the lower pressure roller 71, the electric push rod 76 is 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 the operation is simple and convenient. Under the action of the balance bar 78, the mounting frame 72 is kept in a horizontal state, thereby reducing the possibility of the receiving roller 74 and the lower pressure roller 71 being tilted.

[0033] 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 directly opposite to the laser pen 10. The identification frame 16 includes two mutually perpendicular identification rods, and the laser emitted by the laser pen 10 is directly 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.

[0035] The implementation principle of a high-efficiency die-cutting device in the embodiment of the present application is: When die-cutting materials with good toughness and good elongation, the materials are passed between the receiving roller 74 and the lower pressure roller 71. At this time, the receiving roller 74 is located below the accommodating groove 9, and the bottom of the lower pressure 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 to drive the gear 26 to rotate, and the gear 26 rotates. The movement 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 table 11 and drives the material to be lifted, thereby reducing the running stroke of the upper die seat 12, thereby 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 the initial position, and prepare for the next die-cutting operation.

[0036] When die-cutting materials with high 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, thereby adjusting the height of the lower pressure roller 71 and the receiving roller 74, so that the lower pressure roller 71 and the receiving roller 74 are located at the maximum stroke of the sliding seat 132, and the material is clamped between the receiving roller 74 and the lower pressure roller 71, and is flush with the sliding seat 132, and then the hydraulic cylinder 15 is started, and the hydraulic cylinder 15 drives the hydraulic cylinder 15 to move ... 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, and the driving rod 21 and the rack 25 move synchronously.
