[0005] Therefore, a corrugated paper die-cutting machine and a cutting method are proposed. Summary of the invention

[0006] The purpose of the present invention is to solve the problem that corrugated cardboards are manually placed one by one on conveying rollers for conveying, resulting in a large distance difference between adjacent corrugated cardboards, causing the die-cutter to spend a long time to adjust the corrugated cardboard to the processing point, thus making it inconvenient to continuously process the corrugated cardboard, and to propose a corrugated paper die-cutter and cutting method.

[0007] In order to achieve the above object, the present invention adopts the following technical scheme: a corrugated paper die-cutting machine and a cutting method, comprising a die-cutting machine body, a bracket is installed on the side wall of the die-cutting machine body, and a conveyor belt is installed on the bracket relative to the feed inlet of the die-cutting machine body, and also includes: A feeding structure arranged on the side wall of the conveyor belt for uniformly conveying the corrugated cardboard, the feeding structure comprising a support frame fixedly mounted on the side wall of the conveyor belt, a support plate for driving the movement of the corrugated cardboard, a support plate for facilitating the sliding of the corrugated cardboard, a guide plate for making the corrugated cardboard slide obliquely onto the conveyor belt, and a stepping motor for making the support plate move at a uniform speed; A limiting structure is arranged on the upper surface of the support plate and is used to limit the sliding position of the corrugated paperboard. The limiting structure includes a round rod fixedly installed on the upper surface of the support plate and a baffle for guiding the corrugated paperboard; A vibration structure is arranged on the lower surface of the support plate and is used to vibrate the guide plate. The vibration structure includes a guide rod fixedly installed on the lower surface of the support plate, a top plate and a transmission plate that cooperate with each other to drive the guide plate to vibrate.

[0008] The effects achieved by the above components are as follows: by setting a feeding structure, when die-cutting the corrugated cardboard, the stepper motor is used to drive the support plate to move at a uniform speed, so that the corrugated cardboard will fall evenly onto the conveyor belt, thereby reducing the time spent by the subsequent die-cutting machine body to adjust the corrugated cardboard, thereby improving the processing efficiency of the die-cutting machine body; by setting a limiting structure, in the process of the corrugated cardboard sliding along the surface of the support plate, the baffle will resist the corrugated cardboard, and the corrugated cardboard will slide along the surface of the baffle, so that the corrugated cardboard can be automatically adjusted to a suitable position during the movement of the corrugated cardboard, so that the corrugated cardboard falls to a suitable position on the conveyor belt, which is convenient for the subsequent processing of the corrugated cardboard; by setting a vibration structure, in the process of the movement of the support plate, the guide plate will continue to vibrate, thereby accelerating the corrugated cardboard to fall onto the conveyor belt, thereby accelerating the feeding efficiency.

[0010] The effect achieved by the above components is: when die-cutting the corrugated cardboard, first control the output end of the servo motor to rotate, the output end of the servo motor will drive the lead screw to rotate, the lead screw will drive the threaded tube to move in the direction close to the servo motor with the help of the thread, the adjustment frame will move with the threaded tube, at this time the support plate will gradually rotate to a vertical state under the influence of gravity, the rotation of the support plate will drive the pallet to move, the height of the pallet will drop, so as to facilitate the subsequent stacking of the corrugated cardboard on the pallet, after the placement is completed, control the output end of the servo motor to rotate in the opposite direction, the support plate will rotate from a vertical state to an inclined state, after the adjustment is completed, turn off the servo motor and turn on the stepper motor, the output end of the stepper motor will drive the first gear to rotate, the first gear will drive the second gear to rotate, the second gear will drive the sliding frame to slide along the surface of the rack, The sliding of the sliding frame will drive the support plate to slide along the inner wall of the through hole, and the support plate will drive the corrugated cardboard to slide along the smooth surface of the support plate. When the corrugated cardboard moves to the uppermost end of the support plate, the corrugated cardboard will slide to the surface of the guide plate due to the influence of gravity. At this time, the guide plate will support and guide the corrugated cardboard to ensure that the corrugated cardboard is tilted against the surface of the conveyor belt. At this time, the conveyor belt will be turned on, and the conveyor belt will use friction to drive the corrugated cardboard to move until the corrugated cardboard falls on the surface of the conveyor belt and is fed into the feed port of the die-cutting machine body by the conveyor belt. After that, the die-cutting machine body will process the corrugated cardboard. In this process, the support plate is driven to move at a uniform speed by a stepper motor, so the corrugated cardboard will fall evenly onto the conveyor belt, thereby reducing the time spent on the subsequent die-cutting machine body to adjust the corrugated cardboard, thereby improving the processing efficiency of the die-cutting machine body.

[0011] Preferably, a roller is rotatably connected to the surface of the adjustment frame, and the roller abuts against the lower surface of the support plate.

[0012] The effects achieved by the above components are: the adjusting frame causes the roller to squeeze the supporting plate, and the roller achieves the effect of reducing the friction between the adjusting frame and the supporting plate.

[0013] Preferably, a fixing frame is fixedly connected to the surface of the supporting plate, an extension plate is fixedly connected to the circumferential surface of the threaded tube, and the extension plate is slidably connected to the fixing frame.

[0014] The effect achieved by the above components is that the extension plate follows the threaded tube and slides along the inner wall of the fixed frame, and the fixed frame limits the movement path of the extension plate, thereby limiting the movement path of the threaded tube and supporting the threaded tube.

[0015] Preferably, the arc surface of the round rod is rotatably connected to a round tube, the baffle is fixedly assembled on the circumferential surface of the round tube, the upper surface of the support plate is fixedly connected to an L-shaped plate, a bolt is threadedly connected to the L-shaped plate, one end of the bolt is rotatably connected to a pressure plate, the circumferential surface of the round tube is fixedly connected to an arc plate, and a friction strip is fixedly assembled inside the arc plate.

[0016] The effect achieved by the above components is: when it is necessary to adjust the falling position of the corrugated cardboard, turn the bolt, and the bolt will drive the pressure plate to move away from the arc plate with the help of the thread. When the pressure plate is out of contact with the friction strip, the round tube can be rotated to adjust the position of the baffle. After the adjustment is completed, turn the bolt in the opposite direction. When the pressure plate is against the surface of the friction strip, it will limit the position of the arc plate, thereby limiting the position of the baffle. The baffle will resist the corrugated cardboard, and the corrugated cardboard will slide along the surface of the baffle, so that the corrugated cardboard can be automatically adjusted to a suitable position during the movement of the corrugated cardboard, so that the corrugated cardboard falls to a suitable position on the conveyor belt, which is convenient for subsequent processing of the corrugated cardboard.

[0017] Preferably, an angle groove is provided at a position of the support plate relative to the arc-shaped plate.

[0018] The effect achieved by the above components is that the angle groove can easily grasp the adjustment angle of the baffle, thereby facilitating adjustment.

[0019] Preferably, the circumferential surface of the guide rod is slidably sleeved with a strip plate, the circumferential surface of the guide rod is sleeved with a first spring, the two ends of the first spring are respectively fixedly connected to the strip plate and the support plate, the surface of the first gear is coaxially fixedly equipped with a convex plate, the strip plate is fixedly connected to the top plate, the guide plate is fixedly connected to the transmission plate, the side of the top plate close to the transmission plate is a serrated structure, and the transmission plate rests on the serrated surface of the top plate.

[0020] The effects achieved by the above components are as follows: during the movement of the pallet, the first gear will drive the convex plate to rotate, and the convex plate will squeeze the strip plate. The sliding of the strip plate along the arc surface of the guide rod will stretch the first spring and drive the top plate to slide. The serrated surface of the top plate will squeeze the transmission plate, so that the transmission plate drives the guide plate to vibrate. When the convex plate rotates a certain angle, the first spring will contract, so the strip plate will use the elastic force of the first spring to drive the strip plate to slide in the direction close to the support plate, thereby resetting the strip plate. In this process, the top plate can make the guide plate vibrate. Therefore, during the movement of the pallet, the guide plate will continue to vibrate, thereby accelerating the fall of the corrugated cardboard onto the conveyor belt, thereby accelerating the loading efficiency.

[0021] Preferably, the arc surface of the slide rod is sleeved with a second spring, and two ends of the second spring are fixedly connected to the guide plate and the fixing block respectively.

[0022] The effect achieved by the above components is that when the second spring contracts, the guide plate will drive the transmission plate to slide quickly in the direction close to the top plate, thereby ensuring that the transmission plate can be quickly reset to the serrated surface of the top plate.

[0023] Preferably, one end of the sliding rod away from the guide plate is fixedly connected to a connecting plate.

[0024] The effect achieved by the above components is: after the sliding frame slides to a certain position, it will contact the connecting plate, the connecting plate will drive the sliding rod to slide, the sliding rod will drive the guide plate to slide, the guide plate will stretch the second spring, and the second spring will use its own elastic force to delay the sliding speed of the guide plate, thereby buffering and slowing down the sliding frame, making it convenient to stop the movement of the pallet.

[0025] A cutting method for a corrugated paper die-cutting machine comprises the following steps: S1. Before die-cutting the corrugated cardboard, the output end of the servo motor is controlled to rotate, and the support plate will gradually rotate to a vertical state under the influence of gravity, and the corrugated cardboard is stacked on the pallet; S2, control the output end of the servo motor to rotate in the opposite direction, and the support plate will rotate from the vertical state to the inclined state; S3, turn off the servo motor and turn on the stepper motor. With the help of the stepper motor, the pallet moves at a uniform speed, and the corrugated cardboard will fall evenly onto the conveyor belt. The baffle will resist the corrugated cardboard and make it fall to a suitable position on the conveyor belt. The guide plate will continue to vibrate, and the corrugated cardboard will fall onto the conveyor belt faster. S4, turn on the conveyor belt, and the corrugated cardboard falling on the surface of the conveyor belt will be sent to the feed port of the die-cutting machine body by the conveyor belt; S5. Process the corrugated cardboard with the help of the die-cutting machine body.

[0026] Compared with the prior art, the advantages and positive effects of the present invention are: 1. In the present invention, by setting a feeding structure, when the corrugated cardboard is die-cut, the stepping motor is used to drive the support plate to move at a uniform speed, so that the corrugated cardboard will fall onto the conveyor belt evenly, thereby reducing the time spent on the subsequent die-cutting machine body to adjust the corrugated cardboard, thereby improving the processing efficiency of the die-cutting machine body.

[0027] 2. In the present invention, by setting a limiting structure, when the corrugated cardboard slides along the surface of the support plate, the baffle will resist the corrugated cardboard, and the corrugated cardboard will slide along the surface of the baffle, so that the corrugated cardboard can be automatically adjusted to a suitable position during the movement of the corrugated cardboard, so that the corrugated cardboard falls to a suitable position on the conveyor belt, which is convenient for subsequent processing of the corrugated cardboard.

[0028] 3. In the present invention, by providing a vibration structure, the guide plate will continue to vibrate during the movement of the support plate, thereby accelerating the corrugated cardboard to fall onto the conveyor belt, thereby accelerating the efficiency of loading.

[0029] 4. In the present invention, by providing a second spring, the guide plate can be quickly reset with the help of the elastic force of the second spring, and the sliding speed of the guide plate can be slowed down with the help of the elastic force of the second spring, thereby buffering and slowing down the sliding frame and stopping the movement of the support plate.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0034] like Figure 1-Figure 10 As shown, the present invention provides a corrugated paper die-cutting machine and a cutting method, comprising a die-cutting machine body 1, a bracket 2 is installed on the side wall of the die-cutting machine body 1, a conveyor belt 3 is installed on the bracket 2 relative to the feed inlet of the die-cutting machine body 1, and further comprising: a feeding structure 4 arranged on the side wall of the conveyor belt 3 for uniformly conveying corrugated paperboards, the feeding structure 4 comprising a support frame 401 fixedly installed on the side wall of the conveyor belt 3, a support plate 404 for driving the movement of the corrugated paperboard, a support plate 402 for facilitating the sliding of the corrugated paperboard, and a guide plate 419 for making the corrugated paperboard slide obliquely onto the conveyor belt 3. , a stepper motor 406 for moving the support plate 404 at a uniform speed; a limiting structure 5 arranged on the upper surface of the support plate 402 for limiting the sliding position of the corrugated cardboard, the limiting structure 5 includes a round rod 51 fixedly installed on the upper surface of the support plate 402, and a baffle 53 for guiding the corrugated cardboard; a vibration structure 6 arranged on the lower surface of the support plate 402 for vibrating the guide plate 419, the vibration structure 6 includes at least two guide rods 61 fixedly installed on the lower surface of the support plate 402, a top plate 65 and a transmission plate 66 that cooperate with each other to drive the guide plate 419 to vibrate.

[0035] The specific arrangement and functions of the feeding structure 4, the limiting structure 5 and the vibration structure 6 are described in detail below.

[0036] like Figure 2-Figure 10As shown, the upper end of the support plate 402 is rotatably connected to the support frame 401, a through hole 403 is opened on the surface of the support plate 402, and a sliding frame 405 is slidably connected to the inner wall of the through hole 403. The sliding frame 405 is fixedly connected to the support plate 404, and the support plate 404 and the sliding frame 405 are both slidably connected to the support plate 402. The stepper motor 406 is fixedly assembled on the surface of the sliding frame 405, and the output end of the stepper motor 406 is coaxially fixedly assembled with a first gear 407, the first gear 407 is rotatably connected to the sliding frame 405, and the surface of the sliding frame 405 is rotatably connected to a second gear 408, and the second gear 408 is meshed with the first gear 407. The surface of the support plate 402 is fixedly connected to a rack 409, and the rack 409 is meshed with the second gear 408. A servo motor 410 is fixedly connected to the surface of the bracket 2, and a lead screw 411 is coaxially fixedly connected to the output end of the servo motor 410, and a threaded tube 412 is threadedly connected to the arc surface of the lead screw 411, and one end of the threaded tube 412 is fixedly connected to an adjustment frame 413. Two fixed blocks 417 are fixedly connected to the lower surface of the support plate 402, and a slide rod 418 slides through the fixed block 417, and the slide rod 418 is fixedly connected to the guide plate 419. The upper surface of the support plate 402 is a smooth surface. When the corrugated cardboard is die-cut, the output end of the servo motor 410 is first controlled to rotate, and the output end of the servo motor 410 will drive the lead screw 411 to rotate, and the lead screw 411 will drive the threaded tube 412 to move toward the direction close to the servo motor 410 with the help of the thread, and the adjustment frame 413 will move with the threaded tube 412. At this time, the support plate 402 will gradually rotate to a vertical state under the influence of gravity. The rotation of the support plate 402 will drive the pallet 404 to move, and the height of the pallet 404 will drop, so as to facilitate the subsequent stacking of corrugated cardboard on the pallet 404. After the placement is completed, the output end of the servo motor 410 is controlled to rotate in the opposite direction, and the support plate 402 will rotate from a vertical state to a tilted state. After the adjustment is completed, the servo motor 410 is turned off and the stepper motor 406 is turned on. The output end of the stepper motor 406 will drive the first gear 407 to rotate, and the first gear 407 will drive the second gear 408 to rotate. The second gear 408 will drive the sliding frame 405 to slide along the surface of the rack 409, and the sliding of the sliding frame 405 will drive the pallet 4 04 slides along the inner wall of the through hole 403, and the support plate 404 will drive the corrugated cardboard to slide along the smooth surface of the support plate 402. When the corrugated cardboard moves to the uppermost end of the support plate 402, the corrugated cardboard will slide to the surface of the guide plate 419 due to the influence of gravity. At this time, the guide plate 419 will support and guide the corrugated cardboard to ensure that the corrugated cardboard is tilted against the surface of the conveyor belt 3. At this time, the conveyor belt 3 is turned on, and the conveyor belt 3 will use the friction force to drive the corrugated cardboard to move until the corrugated cardboard falls on the surface of the conveyor belt 3 and is fed into the feed port of the die-cutting machine body 1 by the conveyor belt 3. After that, the die-cutting machine body 1 will process the corrugated cardboard. In this process, the support plate 404 is driven to move at a uniform speed by means of the stepper motor 406, so that the corrugated cardboard will fall evenly onto the conveyor belt 3.This reduces the time spent by the subsequent die-cutting machine body 1 to adjust the corrugated cardboard, thereby improving the processing efficiency of the die-cutting machine body 1.

[0037] The surface of the adjusting frame 413 is rotatably connected to a roller 414, and the roller 414 rests against the lower surface of the support plate 402. The adjusting frame 413 will cause the roller 414 to squeeze the support plate 402, and the roller 414 can reduce the friction between the adjusting frame 413 and the support plate 402. The surface of the support plate 404 is fixedly connected to a fixing frame 415, and the circumferential surface of the threaded tube 412 is fixedly connected to an extension plate 416, and the extension plate 416 is slidably connected to the fixing frame 415. The extension plate 416 follows the threaded tube 412 and slides along the inner wall of the fixing frame 415. The fixing frame 415 can limit the moving path of the extension plate 416, thereby limiting the moving path of the threaded tube 412 and supporting the threaded tube 412.

[0038] like Figure 3 and Figure 6 as well as Figure 7 As shown, the arc surface of the round rod 51 is rotatably connected to the round tube 52, the baffle 53 is fixedly assembled on the circumferential surface of the round tube 52, the upper surface of the support plate 402 is fixedly connected to the L-shaped plate 54, the L-shaped plate 54 is internally threaded with a bolt 55, one end of the bolt 55 is rotatably connected to a pressing plate 57, the circumferential surface of the round tube 52 is fixedly connected to an arc plate 56, and a friction strip 58 is fixedly assembled in the arc plate 56. When it is necessary to adjust the falling position of the corrugated cardboard, the bolt 55 is rotated, and the bolt 55 will drive the pressing plate 57 to move away from the arc plate 56 by means of the thread. When the pressing plate 57 is out of contact with the friction strip 58, the position of the round tube 52 relative to the baffle 53 can be rotated. The position of the corrugated cardboard is adjusted. After the adjustment is completed, the bolt 55 is rotated in the opposite direction. When the pressure plate 57 is against the surface of the friction strip 58, the position of the arc plate 56 will be limited, thereby limiting the position of the baffle 53. The baffle 53 will resist the corrugated cardboard, and the corrugated cardboard will slide along the surface of the baffle 53, so that the corrugated cardboard can be automatically adjusted to a suitable position during the movement of the corrugated cardboard, so that the corrugated cardboard falls to a suitable position on the conveyor belt 3, which is convenient for subsequent processing of the corrugated cardboard. The support plate 402 is provided with an angle groove 59 relative to the position of the arc plate 56. The angle groove 59 can facilitate the adjustment angle of the baffle 53, thereby facilitating adjustment.

[0039] like Figure 5 and Figure 8-Figure 10As shown, the circumferential surface of the guide rod 61 is slidably sleeved with a strip plate 62, and the circumferential surface of the guide rod 61 is sleeved with a first spring 63. The two ends of the first spring 63 are respectively fixedly connected to the strip plate 62 and the support plate 402. The surface of the first gear 407 is coaxially fixedly equipped with a convex plate 64. The strip plate 62 is fixedly connected to the top plate 65. The guide plate 419 is fixedly connected to the transmission plate 66. The side of the top plate 65 close to the transmission plate 66 is a serrated structure. The transmission plate 66 is against the serrated surface of the top plate 65. During the movement of the support plate 404, the first gear 407 will drive the convex plate 64 to rotate, and the convex plate 64 will squeeze the strip plate 62. The strip plate 62 slides along the arc surface of the guide rod 61, stretching the first spring 63 and driving the top plate 65 to slide. The serrated surface of the top plate 65 squeezes the transmission plate 66, so that the transmission plate 66 drives the guide plate 419 to vibrate. When the convex plate 64 rotates a certain angle, the first spring 63 contracts. Therefore, the strip plate 62 drives the strip plate 62 to slide in the direction close to the support plate 402 with the elastic force of the first spring 63, so that the strip plate 62 is reset. In this process, the top plate 65 can make the guide plate 419 vibrate. Therefore, during the movement of the support plate 404, the guide plate 419 will continue to vibrate, thereby In order to speed up the falling of the corrugated cardboard onto the conveyor belt 3 and thus speed up the feeding efficiency, the arc surface of the slide bar 418 is sleeved with a second spring 67, and the two ends of the second spring 67 are respectively fixedly connected to the guide plate 419 and the fixed block 417, and the sum of the elastic forces of the second spring 67 is less than the sum of the elastic forces of the first spring 63. When the second spring 67 contracts, the guide plate 419 will drive the transmission plate 66 to slide quickly in the direction close to the top plate 65, thereby ensuring that the transmission plate 66 can quickly return to the serrated surface of the top plate 65. Since the sum of the elastic forces of the second spring 67 is less than the sum of the elastic forces of the first spring 63, the strip plate 62 will use the second spring 67 to The elastic force of a spring 63 drives the strip plate 62 to slide in the direction close to the support plate 402, so that the strip plate 62 can be reset normally. The end of the sliding rod 418 away from the guide plate 419 is fixedly connected to the connecting plate 68. After the sliding frame 405 slides to a certain position, it will contact the connecting plate 68, and the connecting plate 68 will drive the sliding rod 418 to slide, and the sliding rod 418 will drive the guide plate 419 to slide. The guide plate 419 will stretch the second spring 67, and the second spring 67 will use its own elastic force to delay the sliding speed of the guide plate 419, thereby buffering and slowing down the sliding frame 405, making it convenient to stop the movement of the support plate 404.

[0040] like Figure 1-Figure 10 As shown, a cutting method of a corrugated paper die-cutting machine comprises the following steps: S1. Before die-cutting the corrugated paperboard, the output end of the servo motor 410 is controlled to rotate, and the support plate 402 is gradually rotated to a vertical state under the influence of gravity, and the corrugated paperboard is stacked on the support plate 404; S2, controlling the output end of the servo motor 410 to rotate in the opposite direction, so that the support plate 402 rotates from the vertical state to the inclined state; S3, turn off the servo motor 410 and turn on the stepper motor 406, with the help of the stepper motor 406, the support plate 404 moves at a constant speed, the corrugated cardboard will fall evenly onto the conveyor belt 3, the baffle 53 will resist the corrugated cardboard, so that the corrugated cardboard falls to a suitable position on the conveyor belt 3, the guide plate 419 will continue to vibrate, and the corrugated cardboard will fall onto the conveyor belt 3 faster; S4, turn on the conveyor belt 3, and the corrugated cardboard falling on the surface of the conveyor belt 3 will be sent to the feed port of the die-cutting machine body 1 by the conveyor belt 3; S5. Process the corrugated paperboard with the help of the die-cutting machine body 1.

[0041] The overall working principle is that when the corrugated cardboard is die-cut, the output end of the servo motor 410 is first controlled to rotate, and the output end of the servo motor 410 will drive the lead screw 411 to rotate. The lead screw 411 will drive the threaded tube 412 to move toward the servo motor 410 with the help of the thread. The extension plate 416 follows the threaded tube 412 and slides along the inner wall of the fixed frame 415. The fixed frame 415 limits the movement path of the extension plate 416, thereby limiting the movement path of the threaded tube 412 and supporting the threaded tube 412. The adjustment frame 413 follows the threaded tube 412 to drive the roller 414 to move. At this time, the support plate 402 will gradually rotate to a vertical state under the influence of gravity, and the support plate 402 will gradually rotate to a vertical state under the influence of gravity. The rotation of the support plate 402 will drive the support plate 404 to move, and the height of the support plate 404 will decrease, so as to facilitate the subsequent stacking of corrugated cardboard on the support plate 404. After the placement is completed, the output end of the servo motor 410 is controlled to rotate in the opposite direction. At this time, the adjustment frame 413 will cause the roller 414 to squeeze the support plate 402. The roller 414 can reduce the friction between the adjustment frame 413 and the support plate 402, and the support plate 402 will rotate from a vertical state to a tilted state. After the adjustment is completed, the servo motor 410 is turned off and the stepper motor 406 is turned on. The output end of the stepper motor 406 will drive the first gear 407 to rotate, and the first gear 407 will drive the second gear 408 to rotate. 8 will drive the sliding frame 405 to slide along the surface of the rack 409, and the sliding of the sliding frame 405 will drive the support plate 404 to slide along the inner wall of the through hole 403, and the support plate 404 will drive the corrugated cardboard to slide along the smooth surface of the support plate 402. When the corrugated cardboard moves to the uppermost end of the support plate 402, the corrugated cardboard will slide to the surface of the guide plate 419 due to the influence of gravity. At this time, the guide plate 419 will support and guide the corrugated cardboard to ensure that the corrugated cardboard is tilted against the surface of the conveyor belt 3. At this time, the conveyor belt 3 is turned on, and the conveyor belt 3 will use the friction force to drive the corrugated cardboard to move until the corrugated cardboard falls on the surface of the conveyor belt 3 and is fed into the feed port of the die-cutting machine body 1 by the conveyor belt 3. Then the die-cutting machine body 1 will process the corrugated cardboard. During this process, the stepper motor 406 drives the support plate 404 to move at a uniform speed, so the corrugated cardboard will fall evenly onto the conveyor belt 3, thereby reducing the time spent by the subsequent die-cutting machine body 1 to adjust the corrugated cardboard, thereby improving the processing efficiency of the die-cutting machine body 1. After the sliding frame 405 slides to a certain position, it will contact the connecting plate 68, and the connecting plate 68 will drive the sliding rod 418 to slide, and the sliding rod 418 will drive the guide plate 419 to slide, and the guide plate 419 will stretch the second spring 67. The second spring 67 will use its own elastic force to delay the sliding speed of the guide plate 419, thereby buffering and decelerating the sliding frame 405, making it convenient to stop the support plate 404 from moving.

[0042] When the corrugated cardboard slides along the surface of the support plate 402, the corrugated cardboard will contact the baffle 53. At this time, the baffle 53 will resist the corrugated cardboard, and the corrugated cardboard will slide along the surface of the baffle 53, so that the corrugated cardboard can be automatically adjusted to a suitable position during the movement of the corrugated cardboard, so that the corrugated cardboard falls to a suitable position on the conveyor belt 3, which is convenient for subsequent processing of the corrugated cardboard. When it is necessary to adjust the falling position of the corrugated cardboard, the bolt 55 is rotated, and the bolt 55 drives the pressing plate 57 to move away from the arc plate 56 by means of the thread. When the pressing plate 57 is out of contact with the friction strip 58, the round tube 52 can be rotated to adjust the position of the baffle 53. In this process, the angle groove 59 can facilitate the control of the adjustment angle of the baffle 53, thereby facilitating adjustment. After the adjustment is completed, the bolt 55 is rotated in the opposite direction. When the pressing plate 57 is against the surface of the friction strip 58, the position of the arc plate 56 will be limited, thereby limiting the position of the baffle 53.

[0043] During the movement of the support plate 404, the first gear 407 drives the convex plate 64 to rotate, and the convex plate 64 squeezes the strip plate 62. The strip plate 62 slides along the arc surface of the guide rod 61 to stretch the first spring 63 and drive the top plate 65 to slide. The serrated surface of the top plate 65 squeezes the transmission plate 66. The transmission plate 66 first slides away from the top plate 65 and stretches the second spring 67. When the second spring 67 contracts, the guide plate 419 drives the transmission plate 66 to slide quickly in the direction close to the top plate 65, thereby ensuring that the transmission plate 66 can be quickly reset to rest against the top plate 65. 5, when the convex plate 64 rotates a certain angle, the first spring 63 will contract. Since the sum of the elastic forces of the first spring 63 is greater than the sum of the elastic forces of the second spring 67, the strip plate 62 will slide toward the direction close to the support plate 402 with the help of the elastic force of the first spring 63, so that the strip plate 62 is reset. During this process, the top plate 65 can make the guide plate 419 vibrate. Therefore, during the movement of the support plate 404, the guide plate 419 will continue to vibrate, thereby accelerating the corrugated cardboard to fall onto the conveyor belt 3, thereby accelerating the efficiency of feeding.
