[0024] Preferred embodiments, in combination Figures 7-11 As shown, the gripping component 4 includes a mounting frame 401, suction components 5, a driving component 402, and a fourth hydraulic cylinder 403. The mounting frame 401 is connected to the lifting platform 2 and has multiple working positions 404 for mounting suction components. The outer walls of the multiple suction components 5 are respectively connected to the working positions 404 to form a rotating shaft connection. The suction components 5 are provided with multiple suction cup areas 501. The tail end of the suction component 5 is provided with a connecting pipe 502 fixedly connected to the mounting frame 401. The connecting pipe 502 is connected to the negative pressure device and forms a sleeve with the tail end pipeline of the suction component 5, so as to ensure the connection without affecting the axial displacement and circumferential rotation of the suction component 5. One end of the driving component 402 is connected to the mounting frame 401, and the other end is provided with an assembly that connects to the multiple suction components 5. 405. The driving component 402 can adopt a hydraulic cylinder structure. The assembly 405 includes a straight rod and a vertical arm. One side of the straight rod has multiple first short shafts, and the other side has a second short shaft connected to the driving component 402. One end of the vertical arm is sleeved with the first short shaft, and the other end is fixedly connected to the adsorption component 5. Thus, under the push of the driving component 402, the adsorption component 5 can rotate circumferentially to adjust the angle of the cardboard. The fourth hydraulic cylinder 403 is fixed in front of the mounting frame 401. The push rod of the fourth hydraulic cylinder 403 has a horizontal plate 406 connected to the adsorption component 5. The horizontal plate 406 and the adsorption component 5 are connected by a rotating shaft. By pushing and pulling the fourth hydraulic cylinder 403, the axial adjustment of the adsorption component 5 can be realized, which is convenient for adsorbing the cardboard or adjusting the position of the cardboard. Preferred embodiments, in combination Figures 8-11As shown, a stabilizing sleeve 503 is fitted onto the adsorption component 5. The inner wall of the stabilizing sleeve 503 is slidably connected to the adsorption component 5, and the outer wall of the stabilizing sleeve 503 is pivotally connected to the working position 404. A detachable auxiliary frame 504 is provided on the stabilizing sleeve 503. If a screw connection is used, the stability of the cardboard after being gripped can be enhanced. In addition, during cutting, it can support the upper and lower edges of the cardboard, improve the stability of the cardboard, and prevent local deformation of the cardboard during cutting. Specifically, after the adsorption component 5 grips the cardboard, it moves slightly axially by a certain distance so that the cardboard enters the auxiliary frame 504. The width of the upper and lower edges of the auxiliary frame 504 should be less than the thickness of the cardboard. Furthermore, the detachable auxiliary frame 504 can be selectively adjusted according to the cardboard specifications, enhancing practicality.

[0025] In a preferred embodiment, to ensure stability and reliability during long-term angle adjustments, the following is combined: Figures 10-12 As shown, by providing an angle limiting component 6 at the working position 404, and symmetrically providing limiting rods 505 connected to the angle limiting component 6 on the stabilizing sleeve 503, the rotation direction can be limited, specifically as follows: The angle limiting component 6 includes a control console 7, a control sleeve 8, and a sliding rack 601. The control console 7 contains a positioning disk assembly 9 that contacts the limiting rod 505. The positioning disk assembly 9 provides rotation space for the limiting rod 505 at a certain angle. An inner moving part 701 is located on the right side of the control console 7. A magnetic layer 702 is located inside the control console 7, which uses its own magnetic force to maintain the stability of the positioning disk assembly 9 during adjustment. The control sleeve 8 is slidably connected to the control console 7, with its left end connected to the positioning disk assembly 9 and its right end connected to the inner moving part 701. A first gear 801 is located at the right end. The sliding rack 6... 01 is slidably connected to the mounting bracket 401, and its lower surface is meshed with the first gear 801. The mounting bracket 401 is equipped with an adjustment motor 407, which is meshed with the upper surface of the sliding rack 601. By driving the control sleeve 8 through the inner moving part 701 for fine adjustment, the positioning disk assembly 9 can be separated and snapped at a designated position. This allows for separate adjustment of the two endpoints of the rotation space. The structure is stable and ingenious. At the same time, a protective part 11 is added at the driving part 402. By reserving a safety position and cooperating with the rotation space, the stability and reliability of the angle adjustment can be guaranteed.

[0026] Combination Figure 16As shown, the protective component 11 has a force-bearing rod 1102 inside. The end of the force-bearing rod 1102 is fixedly connected to the push rod of the driving component 402. At the same time, two balance springs 1101 are installed inside the protective component 11, which contact the two sides of the force-bearing rod 1102 to form a balance support. The top of the protective component 11 is fixedly connected to the top of the push rod of the driving component 402. By increasing its own stroke through the driving component 402, such as a displacement of 5 cm to achieve the specified angle adjustment, and increasing it to a displacement of 6 cm, a certain stable distance is reserved, thereby ensuring the stability of angle adjustment under long-term operation, enhancing the reliability of processing, effectively improving product quality, and overcoming the situation of reduced accuracy caused by frequent reciprocating rotation after long-term operation when using a motor to adjust the angle.

[0027] Preferred embodiments, in combination Figures 11-14 As shown, the positioning disk assembly 9 includes a first turntable 901 and a second turntable 902. Positioning channels 903 are symmetrically provided on both the first turntable 901 and the second turntable 902. Engaging holes 904 are provided on the inner circumference of both the first turntable 901 and the second turntable 902, providing engagement positions with the control sleeve 8. The first turntable 901 is connected to the control console 7 and located near the suction element 5. The second turntable 902 is rotatably connected to the control sleeve 8, and a pressure pad 905 is provided on the side near the first turntable 901. The inner moving element 701 can drive the second turntable 902 to move axially, thereby releasing the restriction on the first turntable 901. Subsequently, the control sleeve 8 engages with either the first turntable 901 or the second turntable 902 to achieve circumferential adjustment, thus adjusting the rotation space. Furthermore, the design of the pressure pad 905 increases the friction between it and the first turntable 901 after compression, improving stability. The material can be rubber.

[0028] Combination Figure 17 The control sleeve 8 is provided with a first positioning post 802 and a second positioning post 803 inside, and has a liquid distribution chamber, a liquid inlet pipe and a liquid outlet pipe inside. The two positioning posts can be pushed to extend or retract by hydraulic oil, so as to realize the separate connection of the two turntables and achieve the purpose of separate adjustment. At the same time, the design of the first positioning post requires that it can only be connected to the snap-fit ​​hole 904 after being axially displaced to a specified position. In a preferred embodiment, since the snap-fit ​​hole 904 is in a fixed position, the rotational precision requirement for the control sleeve 8 is too high. If it is not aligned, a snap-fit ​​connection cannot be formed. To address this, a new connection method is provided: the snap-fit ​​hole 904 is removed from the inner circles of both the first turntable 901 and the second turntable 902, and an anti-slip layer is laid on the top of the first positioning post 8020 and the second positioning post 803. After contacting the inner circle, the angle adjustment is achieved by overcoming the magnetic force through friction braking. This is more convenient and reliable. Once the angle of one turntable is adjusted, the other positioning post can be changed to continue the adjustment in the opposite direction.

[0029] Combination Figure 18 As shown, the right side of the control console 7 also has a liquid dispensing chamber, a liquid inlet pipe, and a liquid outlet pipe. The inner moving part 701 is slidably connected to the liquid dispensing chamber, and the hydraulic oil is used to make fine adjustments to the inner moving part, so as to control the control sleeve 8.

[0030] Combination Figure 19 As shown, in order to further improve the positioning stability of the first turntable 901 and the second turntable 902, a brake pressure plate 703 structure is added to the inside of the left side of the control console 7 to clamp the outer circles of the first turntable 901 and the second turntable 902, thereby enhancing stability. At the same time, the piston rod 704 on the brake pressure plate 703 is slidably connected to the internal liquid distribution chamber and is also driven by hydraulic oil to achieve internal control, which is simple and convenient to operate. Preferred embodiments, in combination Figure 14 and Figure 20 As shown, the brake pressure plate 703 has uniformly toothed patterns on its surface, and the first turntable 901 and the second turntable 902 are respectively provided with toothed grooves, which further improves the reliability after clamping.

[0031] Combination Figure 1 , Figure 6 and Figure 15 As shown, in order to facilitate the collection of the cut cardboard, a conveyor belt 10 is added at the lifting platform 2. At the same time, a tail frame 408 structure is added between the mounting frame 401 and the sliding arm 205. The tail frame 408 and the mounting frame 401 are connected by a rotating shaft. The tail frame 408 is equipped with a fifth hydraulic cylinder 409 connected to the mounting frame 401. The fifth hydraulic cylinder 409 can control the mounting frame 401 to rotate counterclockwise by 90 degrees, so that the cut cardboard is placed horizontally on the conveyor belt 10 to achieve the purpose of collection and conveying.

[0032] Combination Figure 2 As shown, a top pressure plate can be added above the limiting plate 105. The pressure plate is slidably connected to the frame 1, and the pressure plate has an adjustment rod that can adjust the extension length of the pressure plate. By cooperating with the limiting plate 105, a gap can be reserved according to the thickness of the cardboard, thereby preventing the cardboard behind from being misaligned during the gripping process.

[0033] Working principle: The cardboard is placed into the discharge area 101 in sequence, and the push plate 104 keeps the cardboard in a vertical position. Then, the lifting platform 2 operates the gripping component 4 to grip the cardboard, and after gripping, it moves back a certain distance and rises to contact the cutting component 3 to complete the cutting of the corners or edges. When cutting the corners, the suction component 5 drives the cardboard to adjust the angle. The cutting edge only needs to be moved upward (when all four edges need to be cut, the auxiliary frame 504 needs to be removed). Then, the position of the cardboard is adjusted again, and the downward movement is performed again. The cutting process can be achieved by moving up and down. The cutting waste falls off under the blowing of the upper air outlet 102 and is collected. Then, the finished cardboard is placed and the above actions are repeated.

[0034] This device adopts a multi-station design, which can process multiple cardboards in one up and one down position, greatly improving processing efficiency. The overall structural design allows waste materials to fall downwards for collection and sorting with the cardboard. Furthermore, the structural design of components such as the gripping component 4 and the angle limiting component 6 improves adjustment accuracy and ensures the quality of the finished product.

[0035] Application Example: A device with three discharge zones (101) was put into actual production by an electronic packaging company for trimming the four corners of 160mm×100mm×2.0mm cardboard. Application results showed that the device significantly improved processing efficiency and product consistency, with a daily processing capacity of 6,800 pieces, a 518% increase compared to traditional manual methods. The cutting angle control accuracy reached ±0.3°, and the pass rate increased from 80% to 99.5%. The edge residue rate decreased from 10.2% to 0.8%, significantly reducing rework requirements. The equipment adopts a multi-station collaborative design, allowing for simultaneous processing... This device processes multiple sheets of cardboard in just 6.8 seconds per cycle, enabling efficient continuous operation. The angle limit component 6 works in conjunction with the drive system to ensure high repeatability of rotational positioning and good consistency in finished product dimensions. Cutting waste is automatically collected by gravity through the air outlet 102, ensuring thorough waste removal without manual intervention. The machine operates stably with an average mean time between failures (MTBF) of over 300 hours, resulting in low maintenance costs. Compared to manual operation, this device reduces the number of operators by 50%, eliminates safety accidents, and increases annual comprehensive benefits by approximately 176,000 yuan. The investment payback period is approximately 2.7 years, demonstrating significant economic viability and promotional value.
