[0029] More specifically, the upper end of the collection box 5 is also provided with a front laminating roller 13, which will roll off the product that the blanking pin 9 has not completely pressed in. The front laminating roller 13 is provided with a conveying element 6 on the side, which will cooperate with the front laminating roller 13 to send the product to the preset position; at the same time, the front laminating roller 13 is used to assist the material to be laminated to the workbench of the die-cutting machine; such a laminating roller is usually located at the feeding end of the die-cutting machine, and its main functions include: helping positioning: the laminating roller can help to accurately position the sheet material on the workbench of the die-cutting machine, ensuring that the position of the material is accurate; improving precision: by pressing the sheet material with the laminating roller, it can ensure that the material does not shift or shake during the die-cutting process, thereby improving the cutting precision and accuracy; preventing wrinkles: the laminating roller can help the sheet material to be flatly laminated to the workbench, preventing wrinkles or material deformation during the die-cutting process; the use of conveying belts during the sheet die-cutting and waste removal process can bring many benefits, including: automated conveying: the conveying belt can realize automated material conveying, reducing manual handling and improving production efficiency; improving production speed: through the conveying belt, continuous material conveying can be realized, improving production speed and capacity, reducing labor intensity: reducing manual handling reduces the labor intensity of workers and improves the comfort of the working environment; improving safety: through the laminating roller to fix the sheet material, it can reduce the risk of accidents during the die-cutting process and improve the operation safety; after the front laminating roller 13 brings part of the product into the conveying element 6, the product completes the collection.

The cooperation of the material winding roller 23 and the guide disc 14 can make the waste material have an oblique upward movement section; the detection gas tank 15 is installed on the support frame 29 arranged at both ends of the collection box 5, which is used to check whether the product and the waste material are completely separated. Through the detection gas tank 15, the phenomenon of easy leakage in the existing waste removal mode can be reduced.

[0031] Further, the outer wall of the detection gas tank 15 is provided with an air suction cavity 19 and a material lifting cavity 28. The opening end of the air suction cavity 19 is parallel to the waste material upward movement section. The air suction cavity 19 and the material lifting cavity 28 are provided with an air pipe 20. The air pipe 20 can communicate the air suction cavity 19 and the material lifting cavity 28. The material lifting piston 18 is slidingly installed in the interior of the material lifting cavity 28. The material lifting piston 18 can separate the product that is not separated under certain conditions. The upper end of the detection gas tank 15 is provided with an air pump 22. The air pump 22 communicates with the air suction cavity 19. The material rolling roller 23 and the guide disc 14 can pull the waste material upward to form a slope. After the air pump 22 is opened, the air suction cavity 19 starts to suck air. At this time, the waste material is adsorbed at the bottom of the detection gas tank 15. At the same time, a lot of dust will be generated in the process of sheet material cutting and waste material discharge. The dust adsorption has the following advantages: improving the working environment; a large amount of dust will be generated in the process of sheet material cutting and waste material discharge. The dust adsorption can effectively reduce the dust concentration in the air, improve the working environment, and protect the health of employees; the dust may fall on the product surface in the process of sheet material cutting and waste material discharge, which affects the quality and appearance of the product.

The dust adsorption can reduce the failure rate of the equipment and prolong the service life of the equipment.

[0032] Further, the inner wall of the air pipe 20 is slidingly installed with a plug 26. The interior of the plug 26 is provided with an L-shaped cavity 27. The end surface of the air pipe 20 is provided with an air passage cavity 24. When the plug 26 slides to the air suction cavity 19, the L-shaped cavity 27 and the air passage cavity 24 are connected and communicated. The inner wall of the air pipe 20 is installed with a spring seat. The spring seat and the plug 26 are fixedly installed with a balance spring 30. The spring seat does not interfere with the communication relationship of the air pipe 20. Please refer to Figure 8 In this embodiment, the product in contact with the bottom of the air suction cavity 19 will be in close contact with the air suction cavity 19 to form a sealed state. At this time, a negative pressure cavity is formed in the interior of the air suction cavity 19. Under normal conditions, the plug 26 is supported by the balance spring 30 to make the air passage cavity 24 and the L-shaped cavity 27 staggered and not communicated. When the product is in contact with the bottom of the air suction cavity 19, a sealed condition is formed in the interior of the air suction cavity 19. At this time, the negative pressure in the interior of the air suction cavity 19 is increased. When the negative pressure reaches the preset pressure, the balance spring 30 under the negative pressure is compressed to make the plug 26 move to make the air passage cavity 24 and the L-shaped cavity 27 communicated. At this time, the air suction cavity 19 and the material lifting cavity 28 are communicated. At this time, the air suction cavity 19 will suck the air in the interior of the material lifting cavity 28 to make the material lifting piston 18 move to lift the product missed by the waste material to separate and complete the detection.

[0033] Specifically, the balance spring 30 will be compressed to make the air passage cavity 24 and the L-shaped cavity 27 communicated when the negative pressure in the air suction cavity 19 reaches the predetermined value. When the product contacts the bottom of the air suction cavity 19 to make the interior of the air suction cavity 19 reach the sealed condition, the balance spring 30 will be compressed before the product is deformed by suction to make the material lifting piston 18 descend to lift the product.

[0034] Specifically, the inside of the support frame 29 is also provided with a receiving tray 17, which can push the product out of the product pushing piston 18 and fall into the conveying member 6. The outside of the support frame 29 is also provided with a protective cover 21, which protects the roll material roller 23 inside. When the product on the waste material is pushed out by the product pushing piston 18 and separated, the falling product will fall onto the receiving tray 17 provided on the inside of the support frame 29. The receiving tray 17 is provided with an inclined surface, which can fall into the conveying member 6. In the die-cutting machine, the roll material roller 23 is used to collect the die-cutting waste. In order to ensure the normal operation and use of the roll material roller 23, a protective cover 21 is usually provided. The roll material roller 23 usually operates at high speed, and the operator may accidentally touch the roll material roller 23, causing a safety accident. The protective cover 21 can effectively prevent this situation and protect the safety of the operator. Prevent waste from splashing: During the die-cutting process, waste may splash, which may cause pollution and damage to the surrounding environment and equipment. The protective cover 21 can effectively prevent waste from splashing and protect the surrounding environment and equipment.

[0035] More specifically, the conveying member 6 includes an upper conveying belt 7 and a lower conveying belt 8. The upper conveying belt 7 cooperates with the front laminating roller 13 and the receiving tray 17, respectively. The output end of the material collecting cavity 12 is connected to the lower conveying belt 8. The bottom of the material collecting cavity 12 is provided with an inclined surface. In order to make the product fall and slide onto the lower conveying belt 8, the efficiency of manual picking can be reduced.

[0036] Further, the front laminating roller 13 and the guide disc 14 are provided with adjusting blocks 25 at both ends. The adjusting blocks 25 can adjust the height of the front laminating roller 13 and the guide disc 14 according to the thickness of the material. The adjusting block 25 automatically adjusts the tension: by connecting the adjusting motor, the tension of the material pulling roller can be automatically adjusted. The adjusting motor can automatically adjust the position of the material pulling roller to maintain appropriate tension, thereby ensuring the normal operation of the conveying belt. Improve production efficiency: automatic adjustment of tension can reduce manual intervention, reduce maintenance and labor costs, and at the same time improve the stability and reliability of the conveying system and improve production efficiency. Reduce equipment wear and tear: by automatically adjusting the tension, the wear and tear of the conveying belt caused by excessive looseness or tightness can be avoided, prolonging the service life of the conveying belt and related equipment. Improve safety: maintaining appropriate tension helps to reduce the risk of deviation and breakage of the conveying belt, improving the safety of the conveying system.

[0037] Further, the upper end of the movable beam 2 is provided with an upper beam 1, and the lower end of the movable beam 2 is provided with a lower beam 3, and a guide column 4 is arranged between the movable beam 2, the upper beam 1 and the lower beam 3, the movable beam 2, the upper beam 1 and the lower beam 3 are generally used for supporting and transmitting pressure components, and the guide column 4 is used for guiding and supporting these beams, and the functions and uses are as follows: guiding effect: the guide column 4 can ensure that the movable beam 2, the upper beam 1 and the lower beam 3 move vertically during the die cutting process, avoiding the inclination or instability caused by uneven stress; supporting effect: the guide column 4 can provide additional support to help the movable beam 2, the upper beam 1 and the lower beam 3 withstand the pressure and impact during the die cutting process, and ensure the precision and stability of the die cutting; protection effect: the guide column 4 can also protect the movable beam 2, the upper beam 1 and the lower beam 3, reduce the friction and vibration of them during the die cutting process, and prolong the service life.

[0038] Working principle: when the power battery protection sheet die cutting and waste discharging device is used, the material is put into the movable beam 2 below through the die cutting assembly, and after the wood cutter 11 is die cut, the material passes through the separating assembly, at this time the guide disc 14 can compact and position the material to move in one direction, and the compacted and positioned material flow is in a taut state, the discharging ejector pin 9 will descend at the same time each time the movable beam 2 descends, so that the die cut material can be separated from the product and the waste, and when the discharging ejector pin 9 is pressed down, the product will be pressed into the material collecting cavity 12, and after the product falls down, it can slide onto the lower conveying belt 8, and part of the product that is not separated will be brought into the conveying part 6 by the front laminating roller 13, and the product is collected, at this time the separated waste will be collected by the detection air tank 15, and the material winding roller 23 winds up to form an inclined slope, at this time the detection air tank 15 starts to detect whether there is a missed product that is not separated, and after the air pump 22 is opened, the suction cavity 19 starts to suck air, at this time the waste is adsorbed at the bottom of the detection air tank 15, and when the bottom of the suction cavity 19 contacts the product that is not separated, the suction of the suction cavity 19 is blocked, at this time a negative pressure cavity is formed in the suction cavity 19, and the negative pressure in the suction cavity 19 moves the air plug 26 in the air pipe 20 to the inside of the suction cavity 19, and at the same time the suction cavity 19 is communicated with the material ejecting cavity 28, at this time the suction cavity 19 sucks the air in the material ejecting cavity 28 to make the material ejecting piston 18 move to eject the waste and the missed product, and the detection is completed, and after the material ejecting piston 18 moves to eject the waste and the missed product, the falling product falls onto the material receiving disc 17 arranged in the inner side of the supporting frame 29, and the material receiving disc 17 is arranged as an inclined surface to make the product fall into the conveying part 6 for collection.
