Description

Technical Field

[0001] The invention relates to the technical field of corrugated paper processing, in particular to a highly efficient and automated corrugated paper cutting and creasing device. Background Art

[0002] Corrugated paper is a plate-like material made of noodle paper and corrugated paper formed by corrugating rollers. It is generally divided into two categories: single corrugated paperboard and double corrugated paperboard. According to the size of the corrugation, it is divided into five types: A, B, C, E, and F. The invention and application of corrugated paper has a history of more than 100 years. It has the advantages of low cost, light weight, easy processing, high strength, excellent printing adaptability, and convenient storage and transportation. More than 80% of corrugated paper can be recycled. Corrugated paper can be used as packaging for food or digital products. It is relatively environmentally friendly and widely used. Corrugated paperboard began in the late 18th century. In the early 19th century, its application increased significantly because of its light weight, low price, wide range of uses, simple production, and recycling and even reuse. By the beginning of the 20th century, it had been fully popularized, promoted and applied for packaging of various commodities. Since packaging containers made of corrugated paperboard have unique properties and advantages in beautifying and protecting the goods inside, they have achieved great success in the competition with various packaging materials. It has become one of the main materials for making packaging containers that has been used for a long time and is showing rapid development.

[0003] For example, the patent with the national authorized patent announcement number CN117001772A discloses a highly efficient and automated corrugated paper cutting and creasing device, which relates to the field of corrugated paper box production technology. The highly efficient and automated corrugated paper cutting and creasing device includes a cutting table, a paper pressing mechanism, a material pushing mechanism, a cutting mechanism and a distance adjusting mechanism. An A motor is fixedly installed on the outer surface of one side of the cutting table, a collecting chamber is provided on one side of the cutting table, and a serrated blade is rotatably installed between the inner walls of both sides of the collecting chamber. The rotating shaft of the A motor is connected to the serrated blade in a transmission manner. The serrated blade passes through the top of the cutting table and extends from the inner part of the collecting chamber to the top of the cutting table. A positioning plate is fixedly installed on the top of the cutting table. The highly efficient and automated corrugated paper cutting and creasing device can adjust and cut according to the different widths of the corrugated paper through the coordinated use of the serrated blade, the A motor, the positioning plate, the paper pressing mechanism and the distance adjusting mechanism, and cooperates with the length cutting of the cutting mechanism to increase the cutting range of the device, and cuts the corrugated paper in place at one time, avoiding the complicated processing flow caused by entering the cutting process twice.

[0004] However, the above-mentioned high-efficiency automatic corrugated paper cutting and indentation device does not have the function of indentation on the corrugated paper while cutting the corrugated paper, and at the same time, it does not have the function of automatically discharging and separating and placing the cut corrugated paper. Operators need additional steps to stack the corrugated paper and separate the stacked corrugated paper, which will increase the complexity and time cost during operation. Moreover, the lack of the indentation function will lead to uneven edges and unsatisfactory folding effects of the corrugated paper, affecting the quality and aesthetics of the final product.

[0022] Preferably, the carrying plate can be pushed out of the slide opening by a third electric push rod.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. Through the design of the storage cylinder, the inclined slide plate, the slide opening, the conveyor belt, the cutting opening, the placing mechanism, the cutting and creasing mechanism and the unloading mechanism, when cutting the corrugated paper, the corrugated paper can be placed on the upper surface of the conveyor belt and conveyed into the cutting opening through the conveyor belt and enter the L-shaped plate, and at the same time, it is on the upper surface of the unloading mechanism and the U-shaped plate. As it is continuously conveyed by the conveyor belt, the corrugated paper can touch one end of the triangular plate at one end of the U-shaped plate, and at the same time, it will be detected by the cutting and creasing mechanism, and the cutting and creasing mechanism can be moved vertically downward, and the creasing end in the cutting and creasing mechanism will preferentially touch the upper surface of the corrugated paper for creasing and pressing operations, and this kind of creasing and pressing operation performed together ensures that the position and stability of the cardboard are accurately controlled before starting to cut, which helps to avoid movement or dislocation during cutting, improves the precision and consistency of cutting, and integrates the functions of creasing and cutting, so that two processes can be completed in one operation, which also saves time and human resources and improves production efficiency;

[0025] With the continuous downward pressure, the cutting end of the cutting and creasing mechanism can cut into the cutting opening, cut the corrugated paper in the U-shaped plate, and place it on the upper surface of the unloading mechanism. Then the unloading mechanism will be pulled and rotated to connect with the inclined slide plate in the storage tube, so that the corrugated paper can be guided into the storage tube and placed on the upper surface of the placing mechanism. After the stacking reaches a certain height, the placing mechanism will slide out from the sliding strip opening, lift up the corrugated paper stacked to a certain height and slide it to the other side. Then the placing mechanism can slide back into the sliding strip opening so that the stacked corrugated paper is on the other side of the storage tube again. Then the placing mechanism can slide back to its original position from the sliding strip opening to receive the cut corrugated paper again. After a certain degree of separation, the paper is moved to the other side again, realizing the function of separating and placing the cut and stacked corrugated paper. The function of automatic separation and placement can quickly and accurately stack the cut corrugated paper in the designated position, reducing the time and labor cost of manual operation, thereby improving the overall production efficiency, and eliminating the need for staff to carry and transfer it multiple times. Staff can carry and transfer multiple groups of stacked corrugated paper at a time, allowing staff to handle multiple groups of corrugated paper at a time, reducing repeated handling and transfer operations, thereby saving human resources and labor costs. Processing multiple groups of corrugated paper at a time means that more workload can be completed in a single operation, significantly improving operating efficiency and production capacity.

[0026] 2. Through the design of the cutting knife, guide block, connecting arm, first electric push rod, connecting tube and ultrasonic sensor, when the conveyor belt transports the corrugated paper and touches one end of the triangle plate at one end of the U-shaped plate, it will be detected by the ultrasonic sensor, and the ultrasonic sensor will send a signal to the controller, and the controller will control the first electric push rod to pull the connecting arm, so that the connecting arm can drive the guide block to slide vertically in the guide groove, and the guide block can drive the cutting knife between them to move vertically downward and slide into the cutting opening to cut the corrugated paper. The position of the corrugated paper is accurately located by this ultrasonic sensor, so that it can ensure that each cutting is carried out in the correct position, thereby improving the cutting accuracy, and the controller automatically starts the first electric push rod according to the signal to vertically pull the cutting knife for cutting. This automated process reduces manual intervention and improves production efficiency.

[0027] 3. Through the design of the indentation plate, the connecting tube, the spring and the pressing column, when the first electric push rod pushes the cutting knife to cut the corrugated paper, the cutting knife will drive the mounting plate at one end to move downward together, and the mounting plate will drive the indentation plate on the lower surface to press on the upper surface of the corrugated paper first, so as to perform the steps of pressing and indenting the corrugated paper. With the continuous downward pressure, the indentation plate can drive the pressing column to slide into the connecting tube and touch one end of the spring at the same time. The spring will apply an elastic force to the pressing column, so that the indentation plate can press on the surface of the corrugated paper through the elastic force, so that it can form an indentation on the surface of the corrugated paper. Through the indentation, an additional longitudinal or transverse support structure can be formed in the middle layer of the corrugated paperboard, which increases the strength and compression resistance of the paperboard. Moreover, through this indentation, the corrugated paper is easier to follow a specific folding line when it needs to be folded or bent, which reduces the damage or poor creases during folding, and improves the operability and appearance of the packaging.

[0028] In addition, the top pressure applied to the corrugated paper by the creasing plate can reduce the deformation or distortion of the corrugated paper during the cutting process, ensuring that the edges after cutting are neat and straight, thereby improving the quality and appearance of the product. In addition, by creasing before cutting, the operational risks caused by the movement or misalignment of the cardboard during cutting can be reduced, the safety and stability of the operation can be improved, and the control accuracy, product quality and production efficiency of the cutting process can be significantly improved.

[0029] 4. Through the design of the extension rod, the second electric push rod, the unloading plate and the docking plate, after the corrugated paper is cut and indented, the controller will control the second electric push rod to pull the docking plate through the piston rod, and the docking plate will drive the unloading plate to be pulled and rotated in the U-shaped plate to be inclined and connected with the inclined slide plate in the storage tube, which can guide the cut corrugated paper on the upper surface of the unloading plate to the storage tube to achieve the purpose of automatic collection. The effect of automatic collection can significantly improve the work efficiency of the production line and reduce manual intervention. The cut corrugated paper can automatically enter the storage tube, speeding up the entire production process.

[0030] 5. Through the design of the linear module, the moving block, the third electric push rod and the bearing plate, when the unloading plate stacks the corrugated paper in the storage tube to a certain thickness, the third electric push rod will push up the bearing plate on the upper surface of the piston rod from the sliding strip opening, so as to lift the stacked corrugated paper. Then, the linear module can drive the bearing plate pushed up on the upper surface of the moving block to move, so as to drive the stacked corrugated paper to move to the other side in the storage tube. Then, the third electric push rod can pull the bearing plate back to the sliding strip opening, so that the linear module can pull the bearing plate on the upper surface of the moving block back to its original position and make it close to the corrugated paper again. The stacked corrugated paper is carried by the machine. If it is stacked to a certain height, the stacked corrugated paper will be moved to the other end for stacking again through the linear module, so that multiple groups of stacked corrugated paper can be stacked in the storage tube for storage, so that the staff can carry and transfer multiple groups of stacked corrugated paper at a time. Handling multiple groups of corrugated paper at a time means that more work can be completed in a single operation, which significantly improves the operating efficiency and production capacity, and reduces the chance of staff frequently carrying corrugated paper, thereby reducing the risk of accidents and human errors and improving work safety.

[0031] When the corrugated paper is guided into the storage tube, if the corrugated paper is skewed, the third electric push rod can be started to push up the corrugated paper through the bearing plate, and the linear module can be used to drive the corrugated paper to lean against the two sides of the inner wall of the storage tube, so that the corrugated paper can be pushed to a neat state. This kind of automated separation and placement can ensure that the corrugated paper is stacked neatly and orderly, avoiding the problem of uneven stacking that may be introduced by manual handling, and improving the consistency and appearance quality of the product.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] See also Figure 1-Figure 11 , this embodiment provides the following technical solutions:

[0046] like Figure 1-Figure 4As shown in the figure, an efficient automatic corrugated paper cutting and indentation device includes: a storage cylinder 1. Four groups of connecting frames 103 are fixedly installed on the upper surface of the storage cylinder 1. A conveyor belt 3 is installed between the four groups of connecting frames 103 in a driving manner. One end of the upper surface of the storage cylinder 1 is fixedly installed with an L-shaped plate 6. A U-shaped plate 106 is fixedly installed on the upper surface of the L-shaped plate 6. A corrugated paper feeding port is formed between the upper surfaces of the U-shaped plate 106 and the L-shaped plate 6. This corrugated paper feeding port is flush with the height of the conveyor belt 3. Guide grooves 108 are opened on both sides inside the U-shaped plate 106. A cutting and indentation mechanism 4 is slidably installed in the guide grooves 108;

[0047] Among them, a discharging mechanism 5 is rotatably installed on the lower surface of the L-shaped plate 6. The discharging mechanism 5 is flush with the cutting and indentation mechanism 4 up and down. One end of the lower surface of the L-shaped plate 6 is fixedly installed with an inclined slide plate 101. The other end of the inclined slide plate 101 is fixedly installed on the upper surface of the storage cylinder 1 and is guided into a square storage bin inside the storage cylinder 1. The discharging mechanism 5 can pull down and rotate the corrugated paper on the upper surface of the discharging mechanism 5 after cutting to align with the inclined slide plate 101 and can guide the corrugated paper into the square storage bin inside the storage cylinder 1;

[0048] Among them, a plurality of slide bar openings 102 are opened on the lower inner surface of the storage cylinder 1. A placing mechanism 2 is fixedly installed on the lower surface of the storage cylinder 1. The bearing end of the placing mechanism 2 slides in the slide bar openings 102 and can protrude from the slide bar openings 102, so that it can push up and move the cut corrugated paper from the square storage bin of the storage cylinder 1.

[0049] A side enclosure plate 104 is fixedly installed on the upper surface of the connecting frame 103. The side enclosure plate 104 is located on both sides of the conveyor belt 3. The conveyor belt 3 can convey the corrugated paper into the corrugated paper feeding port formed between the U-shaped plate 106 and the L-shaped plate 6. One end of the L-shaped plate 6 is fixedly installed with a connecting plate 105. The other end of the connecting plate 105 is对接 with the conveyor belt 3.

[0050] Two triangular plates 107 are fixedly installed at one end of the U-shaped plate 106. The two triangular plates 107 can block the corrugated paper.

[0051] Through the design of the storage tube 1, the inclined slide 101, the slide opening 102, the conveyor belt 3, the cutting opening 109, the placing mechanism 2, the cutting and creasing mechanism 4 and the unloading mechanism 5, when the corrugated paper is cut, the corrugated paper can be placed on the upper surface of the conveyor belt 3 and conveyed into the cutting opening 109 through the conveyor belt 3 and enter the L-shaped plate 6, and at the same time, it is on the upper surface of the unloading mechanism 5 and the U-shaped plate 106. As it is continuously conveyed by the conveyor belt 3, the corrugated paper can touch one end of the triangular plate 107 at one end of the U-shaped plate 106, and at the same time, it will be cut and creasing. When the cutting and creasing mechanism 4 detects the problem, the cutting and creasing mechanism 4 can be moved vertically downward, and the creasing end in the cutting and creasing mechanism 4 will first touch the upper surface of the corrugated paper to perform creasing and pressing operations. Such creasing and pressing operations performed together ensure that the position and stability of the paperboard are accurately controlled before cutting begins, which helps to avoid movement or misalignment during cutting, improves the accuracy and consistency of cutting, and integrates the functions of creasing and cutting, so that two processes can be completed in one operation, which also saves time and human resources and improves production efficiency.

[0052] With continued downward pressure, the cutting end of the cutting and creasing mechanism 4 can cut into the cutting opening 109, cut off the corrugated paper in the U-shaped plate 106, and place it on the upper surface of the unloading mechanism 5. Then the unloading mechanism 5 will be pulled and rotated to connect with the inclined slide plate 101 in the storage tube 1, so that the corrugated paper can be guided into the storage tube 1 and placed on the upper surface of the placing mechanism 2. After the stacking reaches a certain height, the placing mechanism 2 will slide out from the slide opening 102, lift up the corrugated paper stacked to a certain height and slide it to the other side. Then the placing mechanism 2 can slide back into the slide opening 102 to make the stacked corrugated paper be on the other side of the storage tube 1 again. Then the placing mechanism 2 can slide back to its original position from the slide opening 102 to place the cut corrugated paper again. The paper is taken over by the machine, and after being stacked to a certain height, it is moved to the other side again, realizing the function of separating and placing the cut and stacked corrugated paper. The function of automatic separation and placement can quickly and accurately stack the cut corrugated paper in the designated position, reducing the time and labor cost of manual operation, thereby improving the overall production efficiency, and eliminating the need for staff to carry and transfer it multiple times. Staff can carry and transfer multiple groups of stacked corrugated paper at a time, so that staff can handle multiple groups of corrugated paper at one time, reducing repeated handling and transfer operations, thereby saving human resources and labor costs. Moreover, processing multiple groups of corrugated paper at a time means that more workload can be completed in a single operation, significantly improving operating efficiency and production capacity.

[0053] like Figure 5-Figure 6As shown, the cutting and creasing mechanism 4 includes a cutting knife 401, and guide blocks 403 are fixedly installed on both sides of the cutting knife 401. The cutting knife 401 is slidably installed in the guide groove 108 through the guide blocks 403. A connecting arm 404 is fixedly installed on the lower surface of the guide block 403. The connecting arm 404 extends from the guide groove 108 and is connected to the piston rod of the first electric push rod 405. The first electric push rod 405 is fixedly installed on the lower surface of the L-shaped plate 6;

[0054] The cutting blade 401 can cut out from the cutting opening 109 through the first electric push rod 405 , and the cutting opening 109 is opened on the upper surface of the L-shaped plate 6 .

[0055] A mounting plate 402 is fixedly mounted on one end of the cutting knife 401. A sliding groove 410 is provided on the upper surface of the mounting plate 402. A pressing column 411 is slidably mounted in the sliding groove 410. The lower surface of the pressing column 411 slides through the lower surface of the mounting plate 402. An indentation plate 408 is fixedly mounted between the two groups of pressing columns 411. The indentation plate 408 is longer than the cutting knife 401, so that the pressing plate 408 will preferentially touch the upper surface of the corrugated paperboard when cutting the corrugated paper.

[0056] A connecting tube 406 is slidably installed in the sliding groove 410 , and the connecting tube 406 is connected to the sliding groove 410 , so that the top pressure column 411 can slide into the connecting tube 406 for storage, so that the cutting knife 401 can continue to cut into the cutting opening 109 .

[0057] Through the design of the cutting knife 401, the guide block 403, the connecting arm 404, the first electric push rod 405, the connecting tube 406 and the ultrasonic sensor 407, the conveyor belt 3 will be detected by the ultrasonic sensor 407 when it transports the corrugated paper and touches the end of the triangle plate 107 at one end of the U-shaped plate 106. The ultrasonic sensor 407 will send a signal to the controller, and the controller will control the first electric push rod 405 to pull the connecting arm 404, so that the connecting arm 404 can drive the guide block 403 to slide vertically in the guide groove 108, and the guide block 403 can drive the cutting knife 401 to move vertically downward and slide into the cutting opening 109 to cut the corrugated paper. The position of the corrugated paper is accurately located by this ultrasonic sensor 407, so that it can ensure that each cutting is carried out at the correct position, thereby improving the cutting accuracy. The controller automatically starts the first electric push rod 405 according to the signal to vertically pull the cutting knife 401 to perform the cutting operation. This automated process reduces manual intervention and improves production efficiency.

[0058] like Figure 7As shown, a guide column 409 is fixedly installed in the connecting tube 406, and the guide column 409 is slidably inserted in the pressing column 411. A spring 412 is mounted on the outer surface of the guide column 409, and the upper and lower ends of the spring 412 respectively contact between the upper surface of the connecting tube 406 and the lower surface of the pressing column 411.

[0059] An ultrasonic sensor 407 is fixedly installed in the mounting plate 402, and the sensing end of the ultrasonic sensor 407 penetrates from the lower surface of the mounting plate 402 and faces the upper surface of the L-shaped plate 6;

[0060] Among them, the signal output end of the ultrasonic sensor 407 is connected to the signal input end of the controller, and the control output end of the controller is electrically connected to the first electric push rod 405 and the electrical control end of the unloading mechanism 5. The models of the ultrasonic sensor 407 and the controller are LV-MaxSonar-EZ1 and Raspberry Pi respectively.

[0061] Through the design of the indentation plate 408, the connecting tube 406, the spring 412 and the pressing column 411, when the first electric push rod 405 pushes the cutting knife 401 to cut the corrugated paper, the cutting knife 401 will drive the mounting plate 402 at one end to move downward together, and the mounting plate 402 will drive the indentation plate 408 on the lower surface to press on the upper surface of the corrugated paper first, so as to perform the steps of pressing and indenting the corrugated paper, and with the continuous downward pressure, the indentation plate 408 can drive the pressing column 411 to slide into the connecting tube 406 and touch the spring at the same time. 412, and the spring 412 exerts an elastic force on the pressing column 411, so that the indentation plate 408 can be pressed on the surface of the corrugated paper by the elastic force, so that it can form an indentation on the surface of the corrugated paper, and the indentation can form an additional longitudinal or transverse support structure in the middle layer of the corrugated paper, thereby increasing the strength and compression resistance of the paperboard, and through this indentation, the corrugated paper is easier to follow a specific folding line when it needs to be folded or bent, thereby reducing damage or poor creases during folding, and improving the operability and appearance of the package;

[0062] Furthermore, the top pressure applied by the creasing plate 408 to the corrugated paper can reduce the deformation or distortion of the corrugated paper during the cutting process by the cutting knife 401, ensuring that the edges after cutting are neat and straight, thereby improving the quality and appearance of the product. In addition, by creasing before cutting, the operational risks caused by the movement or misalignment of the cardboard during cutting can be reduced, the safety and stability of the operation can be improved, and the control accuracy, product quality and production efficiency of the cutting process can be significantly improved.

[0063] like Figure 8As shown, the unloading mechanism 5 includes a unloading plate 503, which is rotatably mounted between the L-shaped plates 6, the upper surface of the L-shaped plate 6 is flush with the mounting plate 402 and the ultrasonic sensor 407, and a docking plate 504 is fixedly mounted on the lower surface of the unloading plate 503, the docking plate 504 is rotatably connected to the piston rod of the second electric push rod 502, and the other end of the second electric push rod 502 is rotatably mounted in the extension rod 501, and the extension rod 501 is fixedly mounted on one end of the L-shaped plate 6;

[0064] The second electric push rod 502 is also controlled by the controller, and the second electric push rod 502 can pull and rotate the unloading plate 503 to align with the inclined slide plate 101.

[0065] Through the design of the extension rod 501, the second electric push rod 502, the unloading plate 503 and the docking plate 504, after the corrugated paper is cut and indented, the controller will control the second electric push rod 502 to pull the docking plate 504 through the piston rod, and the docking plate 504 will drive the unloading plate 503 to be pulled and rotated in an inclined state in the U-shaped plate 106 and connect with the inclined slide plate 101 in the storage tube 1, so that the cut corrugated paper on the upper surface of the unloading plate 503 can be guided to the storage tube 1 to achieve the purpose of automatic collection. The effect of automatic collection can significantly improve the working efficiency of the production line and reduce manual intervention. The cut corrugated paper can automatically enter the storage tube 1, which speeds up the entire production process.

[0066] like Figure 9-11 As shown, the placement mechanism 2 includes a linear module 201, which is fixedly mounted on the lower surface of the storage tube 1. A third electric push rod 203 is fixedly mounted on both sides of the moving block 202 of the linear module 201. A bearing plate 204 is fixedly mounted on the upper surface of the piston rod of the third electric push rod 203. The bearing plate 204 is located in the slide opening 102 and is flush with the upper surface of the storage tube 1.

[0067] The bearing plate 204 can be pushed out of the slide opening 102 by the third electric push rod 203 .

[0068] Through the design of the linear module 201, the moving block 202, the third electric push rod 203 and the carrying plate 204, when the unloading plate 503 stacks the corrugated paper in the storage tube 1 to a certain thickness, the third electric push rod 203 will push up the carrying plate 204 on the upper surface of the piston rod from the slide opening 102, so as to lift the stacked corrugated paper, and then the linear module 201 can drive the carrying plate 204 pushed up on the upper surface of the moving block 202 to move, so as to drive the stacked corrugated paper to move to the other side in the storage tube 1, and then the third electric push rod 203 can pull the carrying plate 204 back to the slide opening 102, so that the linear module 201 can move the moving block 20 The carrying plate 204 on the upper surface is pulled back to its original position and is used to carry the corrugated paper again. If the stacked corrugated paper reaches a certain height, the stacked corrugated paper will be moved to the other end for stacking by the linear module 201 again, so that multiple groups of stacked corrugated paper can be stacked in the storage cylinder 1 for storage, so that the staff can carry and transfer multiple groups of stacked corrugated paper at one time. Handling multiple groups of corrugated paper at one time means that more work can be completed in a single operation, which significantly improves the operating efficiency and production capacity, and reduces the chance of staff frequently carrying corrugated paper, thereby reducing the risk of accidents and human error operations and improving work safety;

[0069] When the corrugated paper is guided into the storage tube 1, if the corrugated paper is skewed, the third electric push rod 203 can be started to push up the corrugated paper through the supporting plate 204, and the linear module 201 can be used to drive the corrugated paper to lean against the two sides of the inner wall of the storage tube 1, so that the corrugated paper can be pushed to a neat state. This kind of automated separation and placement can ensure that the corrugated paper is stacked neatly and orderly, avoiding the problem of uneven stacking that may be introduced by manual handling, and improving the consistency and appearance quality of the product.

[0070] According to the above technical scheme, the working steps of this scheme are summarized and sorted out: when cutting corrugated paper, the corrugated paper can be placed on the upper surface of the conveyor belt 3 and conveyed into the cutting opening 109 through the conveyor belt 3 and into the L-shaped plate 6, and at the same time it will be on the upper surface of the discharge plate 503, until the corrugated paper is conveyed and touches one end of the triangular plate 107 at one end of the L-shaped plate 106, and it will be detected by the ultrasonic sensor 407, and the ultrasonic sensor 407 will send a signal to the controller, and the controller will control the first electric push rod 405 to pull the connecting arm 404, so that the connecting arm 404 can drive the guide block 403 to slide vertically in the guide groove 108, and the guide block 403 can drive the cutting knife 401 between them to move vertically downward and slide into the cutting The cutter 401 will simultaneously drive the mounting plate 402 at one end to move downward, and the mounting plate 402 will drive the indentation plate 408 on the lower surface to preferentially press against the upper surface of the corrugated paper, so as to perform the steps of pressing and indenting the corrugated paper. With the continuous downward pressure, the indentation plate 408 can drive the pressing column 411 to slide into the connecting tube 406 and simultaneously touch one end of the spring 412, and the spring 412 will apply an elastic force to the pressing column 411, so that the indentation plate 408 can be pressed against the surface of the corrugated paper through the elastic force, so that it can form an indentation on the surface of the corrugated paper, and through this indentation, the corrugated paper can be more easily followed by a specific folding line when it needs to be folded or bent, and the corrugated paper can be pressed and indented. After cutting and creasing, the controller will control the second electric push rod 502 to pull the docking plate 504 through the piston rod, and the docking plate 504 will drive the discharge plate 503 to be pulled and rotated in the U-shaped plate 106 to be inclined and connected with the inclined slide plate 101 in the storage tube 1, so that the corrugated paper cut on the upper surface of the discharge plate 503 can be guided to the storage tube 1 to achieve the purpose of automatic collection. If the corrugated box entering the storage tube 1 is skewed, the third electric push rod 203 can be started to push up the corrugated paper through the supporting plate 204, and the linear module 201 can be used to drive the corrugated paper to lean against the two sides of the inner wall of the storage tube 1, so that the corrugated paper can be pushed to a neat state, and this kind of automatic separation and placement can ensure that the corrugated paper is stacked neatly and orderly. When the corrugated paper is stacked in the storage tube 1 to a certain thickness, the third electric push rod 203 will push the supporting plate 204 on the upper surface of the piston rod from the slide opening 102 to lift the stacked corrugated paper. Then, the supporting plate 204 pushed up on the upper surface of the moving block 202 can be driven to move by the linear module 201, and the stacked corrugated paper can be driven to move to the other side in the storage tube 1. Then, the third electric push rod 203 can pull the supporting plate 204 back to the slide opening 102, so that the linear module 201 can pull the supporting plate 204 on the upper surface of the moving block 202 back to its original position and make it carry the corrugated paper again. If the stacking reaches a certain height, the stacked corrugated paper will be moved to the other end for stacking by the linear module 201 again.The stacked corrugated paper can be stored in the storage tube 1.

[0071] In summary: the efficient and automated corrugated paper cutting and creasing device can perform creasing treatment on the corrugated paper before cutting, and this creasing operation can also press the corrugated paper, so that the position and stability of the cardboard can be accurately controlled before cutting begins, which helps to avoid movement or misalignment during cutting, and improves the cutting accuracy and consistency. After cutting, the cut corrugated paper can also be automatically unloaded and stored and stacked, and the corrugated paper can be separated and placed while stacking. The automatic separation and placement function can quickly and accurately stack the cut corrugated paper in the designated position, reducing the time and labor cost of manual operation, thereby improving the overall production efficiency, and eliminating the need for staff to carry and transfer it multiple times. Staff can carry and transfer multiple groups of stacked corrugated paper at a time, so that staff can handle multiple groups of corrugated paper at one time, reducing repeated handling and transfer operations.
