Description

Technical Field

[0001] The present application relates to the field of die-cutting, and in particular, to a printed matter die-cutting machine and a die-cutting process. Background Art

[0002] Traditional die-cutting refers to a cutting process for the post-processing of printed matter. The die-cutting process can cut printed matter or other paper products into a die-cutting plate according to a pre-designed pattern, so that the shape of the printed matter is no longer limited to straight edges and right angles. In traditional die-cutting production, die-cutting knives are combined into a die-cutting plate according to the pattern required by the product design. Under the action of pressure, the printed matter or other sheet-shaped blanks are rolled and cut into the required shape or cut marks. Its packaging printing needs to be cut by a die-cutting machine.

[0003] In the related art, a Chinese patent with the authorization announcement number CN115503043A discloses a die-cutting machine for packaging printing and its die-cutting process, including an external die-cutting mechanism. The external die-cutting mechanism includes a housing. A cutting tool device is slidably installed at the top left of the housing. A fixed clamping device is movably installed inside the housing. The fixed clamping device includes a fastening component. The fastening component is arranged inside and outside the external die-cutting mechanism. Clamping components are fixedly installed on the inner side of the fastening component and inside the external die-cutting mechanism. The fastening component includes a threaded rod. The threaded rod is arranged on the inner and outer sides of the housing. Moving columns are threadedly connected to the outer wall of the threaded rod. Support blocks are fixedly connected to the front and rear sides of the moving columns and outside the housing. The inner ends of the support blocks are fixedly connected to suction cups. The other side of the suction cup adsorbs on the outer wall of the housing. The other side of the threaded rod and inside the housing are fixedly connected to a first fixing plate. The clamping component includes a fixed block. The fixed block is arranged on the inner side of the first fixing plate. Fixed columns are fixedly connected to the upper and lower sides of the fixed block. Upper clamping plates are movably connected to the outer walls above the fixed columns. Lower clamping plates are movably connected to the outer walls below the fixed columns. A transportation device is movably installed at the bottom right of the external die-cutting mechanism.

[0004] By installing the cutting tool device, it is possible to complete die-cutting of the packaging from left to right in continuous sliding, and the die-cutting speed for one-time completion is faster. By installing the fixed clamping device, according to the model size of the packaging to be die-cut this time, the length of the threaded rod inside the housing is moved, and the distance between the upper clamping plate and the lower clamping plate is adjusted. The four corners of the packaging bag are respectively placed between the upper pressing plate and the lower pressing plate and clamped. By installing the transportation device, it is possible to fix the transportation device during die-cutting and wait for the die-cutting to end. Then, the fixed component can be moved to move the transport vehicle.

[0005] The following defects exist in the above related technologies: Whenever a printed matter is cut, it is necessary to readjust the fixed clamping device, the distance between the movable upper clamping plate and the lower clamping plate, take out the cut printed matter from the housing, and then place a new printed matter to be cut into the housing, and adjust the position of the printed matter and the distance between the upper clamping plate and the lower clamping plate to clamp and fix the printed matter. When there are many printed matters to be cut, the above steps need to be repeated many times, which is inconvenient to operate and affects work efficiency. Therefore, it needs to be improved. Summary of the Invention

[0006] In order to improve the problem that when a large number of printed matters need to be cut, the fixed clamping device needs to be adjusted repeatedly, resulting in low work efficiency, the present application provides a printed matter die-cutting machine and a die-cutting process.

[0007] In a first aspect, a printed matter die-cutting machine provided by the present application adopts the following technical solution:

[0008] A printed matter die-cutting machine for cutting printed matters, comprising:

[0009] A die-cutting box, the top of the die-cutting box is an open structure;

[0010] A telescopic plate, arranged in the die-cutting box and used for supporting the printed matter;

[0011] A cutting knife, located in the die-cutting box and used for cutting the printed matter;

[0012] A mounting rod, slidably connected to the top wall of the die-cutting box, and a motor for driving the cutting knife to rotate is arranged on the mounting rod;

[0013] A plurality of abutting plates are arranged on two opposite inner walls of the die-cutting box, and the plurality of abutting plates are slidably connected to the die-cutting box in the vertical direction. An air suction hole is arranged on one side of the abutting plate close to the bottom wall of the die-cutting box;

[0014] A plurality of air suction pipes are arranged on the outer side wall of the die-cutting box. The air suction pipes are communicated with the air suction holes through hoses. A piston is arranged in the air suction pipes. The circumferential side wall of the piston is in contact with the inner wall of the air suction pipes. The piston is connected with a pull rod, and one end of the pull rod away from the piston extends out of the air suction pipe.

[0015] By adopting the above technical solution, during use, stack a number of printed materials to be cut in the die-cutting box. Then, move several abutting plates downward simultaneously until they abut against the topmost printed material. The printed material blocks the air suction holes. Pull the pull rod to drive the piston to move away from the die-cutting box, thereby extracting the gas in the hose, and then adsorb the topmost printed material on the abutting plate. Then, move the abutting plate upward to drive the topmost printed material to move to be flush with the cutting knife. Next, extend the telescopic plate so that the telescopic plate moves below the upper-layer printed material and abuts against the printed material. Under the action of gravity, the abutting plate presses and fixes the printed material on the telescopic plate, realizing the fixation of the printed material on the telescopic plate. Then, move the mounting rod to drive the cutting knife to slide on the die-cutting box while starting the motor to make the cutting knife rotate, so that the cutting knife cuts the printed material to the specified size. When cutting the next printed material, first move the printed material to separate it from the abutting plate, which is convenient for taking away the cut printed material. Then, reset the telescopic plate. Next, move the abutting plate downward to abut against the next-layer printed material, and repeat the above steps to realize the sequential cutting of the stacked printed materials. It realizes automatic feeding, is convenient to operate, and improves work efficiency.

[0016] Optionally, an air intake assembly is provided in the air suction pipe, and the air intake assembly includes:

[0017] Two baffles are arranged between the piston and the hose. The two baffles are arranged oppositely, and both of the two baffles are connected to the inner wall of the air suction pipe. The end of the baffle away from the connection with the inner wall of the air suction pipe is inclined towards the direction close to the piston;

[0018] Two torsion springs, corresponding to the baffles one by one, are arranged at the connection between the baffle and the inner wall of the air suction pipe, and are used to drive the ends of the two baffles away from the connection with the inner wall of the air suction pipe to fit together;

[0019] An air outlet hole is penetrated through the side wall of the air suction pipe. The air outlet hole is located between the piston and the baffle, and an air outlet one-way valve is arranged in the air outlet hole.

[0020] By adopting the above technical solution, when the piston moves away from the die-cutting box and sucks the air in the hose, the air outlet one-way valve prevents the gas outside the air suction pipe from entering the air suction pipe. Similarly, the air outlet one-way valve also enables the piston to reset. During the air suction process, the airflow applies a force to push the two baffles towards the piston, causing the baffles to rotate, that is, the ends of the two baffles away from the torsion spring are separated, so that the air suction pipe and the hose are communicated, and all the gas in the hose enters the air suction pipe and is located between the piston and the baffle, making the hose in a vacuum state, so as to adsorb the printed matter on the abutting plate. When the pull rod stops moving, the baffle resets under the action of the torsion spring, that is, the ends of the two baffles away from the torsion spring fit together to block the air suction pipe, preventing the gas between the piston and the baffle from entering the hose again, that is, keeping the hose in a vacuum state, thereby increasing the stability of adsorbing the printed matter.

[0021] Optionally, the telescopic plate includes:

[0022] A support sleeve, which is horizontally arranged in the die-cutting box, and one side of the support sleeve is connected to the inner wall of the die-cutting box;

[0023] A support plate, which is horizontally inserted into the support sleeve. An electric push rod is fixed in the support sleeve, and the output end of the electric push rod is connected to the support plate for driving the support plate to move in the support sleeve.

[0024] By adopting the above technical solution, when the abutting plate drives the printed matter to move to be flush with the cutting knife, the electric push rod is started to drive the support plate to move away from the support sleeve, changing the length of the support plate extending out of the support sleeve until the support plate moves below the printed matter and abuts against the printed matter. At this time, the electric push rod is stopped, so that the support plate will not displace and maintains the state of supporting the printed matter, facilitating the subsequent cutting of the printed matter by the cutting knife.

[0025] Optionally, it further includes an adjusting assembly for adjusting the height of the telescopic plate. The adjusting assembly includes:

[0026] An adjusting rod, an adjusting groove is vertically formed on the inner wall of the die-cutting box, and the adjusting rod is vertically arranged in the adjusting groove and can rotate in the adjusting groove;

[0027] An adjusting block, which is fixed on the side wall of the support sleeve. The adjusting block is adaptively inserted into the adjusting groove and can move in the adjusting groove. The adjusting rod passes through the adjusting block and is threadedly connected to the adjusting block.

[0028] By adopting the above technical solution, since the heights of the printed products stacked in the die-cutting box are unequal, the adjusting rod is rotated, and the adjusting block is in threaded cooperation with the adjusting rod, so that the adjusting block drives the support sleeve to move along the length direction of the adjusting groove, so as to change the height of the support plate. When the abutting plate drives one of the printed products to move to a height higher than the stacked printed products, the support plate can move to the corresponding height and support the printed products, with good applicability.

[0029] Optionally, it further includes a conveying assembly for conveying the printed products after cutting. A moving hole for the printed products to move out of the die-cutting box is penetrated and opened on one side of the die-cutting box facing the opening of the support sleeve. The conveying assembly includes:

[0030] A connecting block, fixedly arranged on the output end of the electric push rod;

[0031] A connecting rod, the support plate is hinged to the connecting block through the connecting rod. A connecting groove is opened on the side wall of the support sleeve in the horizontal direction, and the end of the connecting rod is inserted into the connecting groove and can move in the connecting groove.

[0032] By adopting the above technical solution, when the printed products are cut on the support plate, the electric push rod is started to drive the support plate to continue to move away from the support sleeve, that is, the connecting rod moves in the connecting groove, and the inner wall of the connecting groove abuts against the side wall of the connecting rod, playing a role of restricting and guiding the connecting rod, so that the support plate can only move along the length direction of the connecting groove, and at the same time the connecting rod cannot move out of the connecting groove, that is, the support plate will not be completely separated from the support sleeve. When the support plate drives the printed products on the support plate to pass through the moving hole, the connecting rod also moves to the end of the connecting groove. At this time, the support plate completely moves out of the support sleeve, and under the action of gravity, the support plate rotates downward with the connecting rod as the axis, so that the cut printed products slide out of the die-cutting box.

[0033] Optionally, a rubber ring is arranged on one side of the abutting plate close to the bottom wall of the die-cutting box, and the rubber ring is coaxial with the air suction hole.

[0034] By adopting the above technical solution, when the abutting plate drives the rubber ring to abut against the printed products, the air suction pipe extracts the air in the hose, adsorbing the printed products on the rubber ring. The rubber ring plays a protective role, making the surface of the printed products not easy to wear. At the same time, the rubber ring also plays a sealing role, making the printed products adsorbed on the rubber ring more firmly.

[0035] Optionally, a moving rod is arranged on the outside of the die-cutting box, and a plurality of the abutting plates are fixedly connected to the moving rod.

[0036] By adopting the above technical solution, after the printed matter is adsorbed on the rubber ring, the moving rod moves up and down, driving several abutting plates to move synchronously, so that there is no height difference at the points where the printed matter contacts the several abutting plates, that is, the printed matter is not easily subjected to the pulling force in the inclined direction, so that the printed matter is not easily separated from the abutting plate, and the fastening property between the printed matter and the adsorption on the rubber ring is increased.

[0037] Optionally, a guiding block is fixed on the side wall of the moving rod, and a guiding groove is arranged on the outer side wall of the die-cutting box along the vertical direction. The guiding block is inserted into the guiding groove and can move in the guiding groove.

[0038] By adopting the above technical solution, when the moving rod moves, the guiding block moves in the guiding groove, and the inner wall of the guiding groove abuts against the side wall of the guiding block, playing a role in restricting and guiding the guiding block, so that the moving rod can only move along the vertical direction without deviation, so that several abutting plates move simultaneously and always remain on the same horizontal plane.

[0039] Optionally, a sliding rod is slidably connected to the moving rod, a pull rope is connected to the pull rod, and one end of the pull rope far away from the pull rod is fixed to the sliding rod.

[0040] By adopting the above technical solution, when it is necessary to extract the air in the hose, the sliding rod is moved in a direction away from the die-cutting box, driving the pull rope to move, so that several pull rods drive the piston to move in the air suction pipe, so as to realize the simultaneous extraction of the air in several hoses, and there is no need to pull the pull rod in sequence to extract the air in the hose, and the operation is convenient.

[0041] In a second aspect, the present application provides a die-cutting process for a printed matter die-cutting machine, which adopts the following technical solution:

[0042] S1. Stack the printed matter to be cut in the die-cutting box, then move the moving rod downward so that the abutting plate drives the rubber ring to abut against the top wall of the topmost printed matter, and then move the sliding rod in a direction away from the die-cutting box, so that the pull rope pulls the pull rod to move, that is, the piston moves in the air suction pipe in a direction away from the die-cutting box to extract the air in the hose, and further adsorb the topmost printed matter on the rubber ring;

[0043] S2. Move the moving rod upward to drive the printed matter to move upward until it is flush with the bottom wall of the cutting knife, then start the electric push rod, push the support plate in a direction away from the support sleeve until the support plate is located below the printed matter, and remove the force for lifting the moving rod, so that the abutting plate presses and fixes the printed matter on the support plate under the action of gravity;

[0044] S3. Then move the mounting rod, drive the cutting knife to slide on the die-cutting box while starting the motor to make the cutting knife rotate, so that the cutting knife cuts the printed matter to the specified size;

[0045] S4. Then use the pull rod to push the piston to reset, move the abutment plate upward to move the printed product, so that the rubber ring is separated from the printed product, start the electric push rod again, and continue to push the support plate, thereby driving the cut printed product to move in the direction of the moving hole. When the connecting rod moves to the end of the connecting groove, the end of the support plate passes through the moving hole and the entire support plate completely moves out of the support sleeve. At this time, the support plate rotates downward with the connecting rod as the axis under the action of gravity, thereby sending the printed product on the support plate out of the die-cutting box.

[0046] By adopting the above technical solution, when in use, a number of printed products are neatly stacked in the die-cutting box, and then the moving rod is moved down so that the abutment plate drives the rubber ring to abut against the top wall of the printed product on the top layer, and then the sliding rod is moved in the direction away from the die-cutting box, so that the pull rope pulls the pull rod to move, that is, the piston moves in the suction pipe in the direction away from the die-cutting box, extracts the air in the hose, and makes the hose in a vacuum state, so that the printed product on the top layer is adsorbed on the rubber ring. Then the moving rod is moved up, and the printed product on the top layer can be driven to move up together until the printed product moves to be flush with the cutter. Then the electric push rod is started to extend the length of the support plate extending out of the support sleeve until the support plate is located below the printed product and abuts against the printed product. At this time, the abutment plate moves down under the action of gravity, and the gravity of several abutment plates is sufficient to press and fix the printed product on the support plate. Then the mounting rod is moved to drive the cutter to slide on the die-cutting box, and the motor is started at the same time, so that the cutter cuts the printed product. Finally, lift the abutment plate and move the printed product so that it falls off the abutment plate, so that the cut printed products all fall onto the support plate, start the electric push rod, so that the support plate drives the printed product to pass through the moving hole until the connecting rod moves to the end of the connecting groove close to the mounting hole. At this time, the support plate also completely moves out of the support sleeve, and the support plate flips downward under the action of gravity, thereby sending the printed product on the support plate out of the die-cutting box.

[0047] In summary, the present application includes at least one of the following beneficial effects:

[0048] 1. When the abutment plate abuts against the printed product, the printed product blocks the air intake hole, and then the piston is used to move and extract the air in the hose, so that the printed product is adsorbed on the abutment plate. Then the abutment plate is moved to the top of the telescopic plate, and the support plate is pulled out of the support sleeve. Then the gravity of the abutment plate is used to press and fix the printed product on the support plate. Then the motor is started while the mounting rod is moved, so that the cutter rotates and moves along the length direction of the die-cutting box on the printed product to achieve cutting of the printed product.

[0049] 2. Since the heights of the printed materials stacked in the die-cutting box are not equal, the adjusting rod is rotated. The adjusting block is in threaded engagement with the adjusting rod, so that the adjusting block drives the support sleeve to move along the length direction of the adjusting groove, thereby changing the height of the support plate. When the abutting plate drives one of the printed materials to move to a height higher than the stacked printed materials, the support plate can move to the corresponding height and support the printed materials, which has good applicability.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0056] The following Figures 1-5 further elaborates on the present application in detail.

[0057] An embodiment of the present application discloses a printed material die-cutting machine. Refer to Figure 1 and Figure 2, The printing die-cutting machine includes a die-cutting box 10. The top of the die-cutting box 10 is an open structure. One side of the die-cutting box 10 is penetrated with a moving hole 12. A number of abutting plates 20 are arranged on the die-cutting box 10. The number of abutting plates 20 is located on the opposite side walls of the die-cutting box 10. A number of moving grooves are opened vertically on the opposite side walls of the die-cutting box 10. The abutting plates 20 correspond to the moving grooves one by one. The abutting plate 20 is an L-shaped plate. One end of the abutting plate 20 in the horizontal direction penetrates the moving groove and can move up and down in the moving groove. One end of the abutting plate 20 in the vertical direction extends downward. An air suction hole 21 is opened on one side of the abutting plate 20 close to the bottom wall of the die-cutting box 10. A rubber ring 22 is fixed on the bottom wall of the abutting plate 20. The rubber ring 22 is coaxial with the air suction hole 21. The air suction hole 21 is communicated with a hose 60. The hose 60 passes through the abutting plate 20 and is coiled in the die-cutting box 10.

[0058] Referring to Figure 3 and Figure 4 , An air suction pipe 40 is fixed on the outer side wall of the die-cutting box 10. The air suction pipe 40 is horizontally arranged. The connection part between the air suction pipe 40 and the die-cutting box 10 is communicated with one end of the hose 60 far from the abutting plate 20. A piston 50 is arranged in the air suction pipe 40. The circumferential side wall of the piston 50 abuts against the inner wall of the air suction pipe 40. The piston 50 is fixedly connected with a pull rod 51. One end of the pull rod 51 far from the die-cutting box 10 extends out of the air suction pipe 40.

[0059] Referring to Figure 1 and Figure 5 , A telescopic plate 30 is arranged in the die-cutting box 10. The telescopic plate 30 includes a support sleeve 31 and a support plate 32. The support sleeve 31 is horizontally arranged in the die-cutting box 10. One side of the support sleeve 31 is connected with the inner wall of the die-cutting box 10 through an adjusting component 80. One side of the support sleeve 31 close to the moving hole 12 is an open structure. The support plate 32 is inserted into the support sleeve 31 and can move in the support sleeve 31.

[0060] Referring to Figure 1 and Figure 2 , A mounting rod 150 is slidably connected to the top wall of the die-cutting box 10 along the width direction of the die-cutting box 10. A motor 160 is fixed on the mounting rod 150 through a bolt. The output end of the motor 160 is vertically downward and fixedly connected with a rotating bevel gear. The rotating bevel gear meshes with a driving bevel gear. The driving bevel gear is vertically arranged and coaxially fixed with a cutting knife 140.

[0061] During use, stack several printed materials to be cut in the die-cutting box 10. Then, simultaneously move several abutting plates 20 downward until the rubber ring 22 abuts against the topmost printed material, blocking the air suction holes 21. Pull the pull rod 51 to drive the piston 50 to move away from the die-cutting box 10, thereby extracting the gas in the hose 60. The rubber ring 22 plays a sealing role, and then adsorbs the topmost printed material on the abutting plate 20. Then, move the abutting plate 20 upward to drive the topmost printed material to move to be flush with the cutting knife 140. Next, extend the telescopic plate 30 so that the telescopic plate 30 moves below the upper-layer printed material and abuts against the printed material. At this time, the gravity of the abutting plate 20 is sufficient to press and fix the printed material on the telescopic plate 30, realizing the fixation of the printed material on the telescopic plate 30. Then, move the mounting rod 150, drive the cutting knife 140 to slide on the die-cutting box 10 and start the motor 160 at the same time, so that the cutting knife 140 rotates, thereby cutting the printed material to the specified size. When the next printed material needs to be cut, first dial the printed material to separate it from the rubber ring 22, which is convenient for taking away the cut printed material. Then, reset the telescopic plate 30, and then move the abutting plate 20 downward to abut against the next layer of printed material, repeating the above steps to realize the sequential cutting of the stacked printed materials. It realizes automatic feeding, is convenient to operate, and improves work efficiency.

[0062] Refer to Figure 2 and Figure 5 , the adjusting assembly 80 includes an adjusting rod 81 and an adjusting block 82. An adjusting groove 11 is vertically formed on the inner wall of the die-cutting box 10. The adjusting rod 81 is in a vertical state and placed in the adjusting groove 11. The top end of the adjusting rod 81 is driven by a servo motor 160 to rotate in the adjusting groove 11. The adjusting block 82 is adaptively inserted into the adjusting groove 11. The adjusting rod 81 passes through the adjusting block 82 and is threadedly connected to the adjusting block 82. The adjusting block 82 is integrally formed with one side of the support sleeve 31 away from the moving hole 12.

[0063] Since the heights of the printed materials stacked in the die-cutting box 10 are different, rotate the adjusting rod 81. The adjusting block 82 is in threaded cooperation with the adjusting rod 81, so that the adjusting block 82 drives the support sleeve 31 to move along the length direction of the adjusting groove 11 to change the height of the support plate 32.

[0064] Refer to Figure 1, in order to synchronously move several abutting plates 20, so that there is no height difference at the points where the printed matter contacts the several abutting plates 20, that is, the printed matter is not easily subjected to a pulling force in the tilting direction, and the fastening property between the printed matter and the rubber ring 22 adsorbed thereon is increased. A moving rod 110 is arranged on the outer side of the die-cutting box 10. Several abutting plates 20 are fixedly connected to the moving rod 110. A guiding block 120 is integrally formed on the side wall of the moving rod 110. A guiding groove 13 is vertically formed on the outer side wall of the die-cutting box 10. The guiding block 120 is inserted into the guiding groove 13 and can move in the guiding groove 13.

[0065] Refer to Figure 1 , similarly, when several rubber rings 22 are all in contact with the printed matter, in order to be able to simultaneously pull the piston 50 to move without pulling the pull rod 51 one by one, a sliding rod 130 is arranged on the moving rod 110. A sliding hole is formed on the moving rod 110. The sliding rod 130 is inserted into the sliding hole and can move in the sliding hole.

[0066] Refer to Figure 3 and Figure 4 , when the rubber ring 22 is in contact with the printed matter and the suction pipe 40 sucks the hose 60 into a vacuum, in order to prevent air from entering the hose 60, that is, to ensure that the printed matter is adsorbed on the rubber ring 22, an air inlet assembly 70 is arranged in the suction pipe 40. The air inlet assembly 70 includes two baffles 71 and two torsion springs 72. The two baffles 71 are arranged oppositely and are located between the piston 50 and the hose 60. The two sides of the two baffles 71 away from each other are hinged to the inner wall of the suction pipe 40 through a rotating shaft. The end of the baffle 71 away from the rotating shaft is inclined towards the direction close to the piston 50. The torsion spring 72 is sleeved on the rotating shaft, and one end of the torsion spring 72 is connected to the inner wall of the suction pipe 40, and the other end is connected to the baffle 71, and is used to drive the ends of the two baffles 71 away from the connection with the inner wall of the suction pipe 40 to fit together. In order to enable the piston 50 to reset, an air outlet hole 41 is formed through the inner wall of the suction pipe 40. The air outlet hole 41 is located between the piston 50 and the baffle 71. An air outlet one-way valve 411 is arranged in the air outlet hole 41.

[0067] Refer to Figure 1 and Figure 5, To facilitate the movement of the support plate 32 within the support sleeve 31 and ensure that the support plate 32 can stably maintain a corresponding extended length from the support sleeve 31 without easy random change, an electric push rod 312 is fixed within the support sleeve 31 by bolts. The output end of the electric push rod 312 is connected to the support plate 32 and is used to drive the support plate 32 to move in the horizontal direction. To enable the cut printed products to be conveyed out of the die-cutting box 10, a conveying assembly 90 is provided on the support sleeve 31. The conveying assembly 90 includes a connecting block 91 and a connecting rod 92. The connecting block 91 is fixed to the output end of the electric push rod 312. The connecting rod 92 is perpendicular to the moving direction of the support plate 32. The connecting rod 92 passes through the connecting block 91 and the support plate 32. Connecting grooves 311 are horizontally formed on the opposite side walls of the support sleeve 31. The end of the connecting rod 92 is inserted into the connecting groove 311 and can move within the connecting groove 311.

[0068] After the printed product is cut on the support plate 32, the electric push rod 312 is activated to drive the support plate 32 to continue moving away from the support sleeve 31, that is, the connecting rod 92 moves within the connecting groove 311. The inner wall of the connecting groove 311 abuts against the side wall of the connecting rod 92, playing a role in restricting and guiding the connecting rod 92, so that the support plate 32 can only move along the length direction of the connecting groove 311. At the same time, the connecting rod 92 cannot move out of the connecting groove 311, that is, the support plate 32 will not be completely separated from the support sleeve 31. When the support plate 32 drives the printed product located on the support plate 32 to pass through the moving hole 12, the connecting rod 92 also moves to the end of the connecting groove 311. At this time, the support plate 32 completely moves out of the support sleeve 31. Under the action of gravity, the support plate 32 rotates downward with the connecting rod 92 as the axis, so that the cut printed product slides out of the die-cutting box 10.

[0069] The implementation principle of a printed product die-cutting machine according to an embodiment of the present application is as follows: During use, a number of printed products are neatly stacked within the die-cutting box 10. Then, the moving rod 110 is moved downward, so that the abutting plate 20 drives the rubber ring 22 to abut against the top wall of the uppermost printed product. At this time, the printed product blocks the air suction hole 21. Then, the sliding rod 130 is moved away from the die-cutting box 10, so that the pulling rope 511 pulls the pull rod 51 to move, that is, the piston 50 moves away from the die-cutting box 10 within the air suction pipe 40, extracting the air in the hose 60, making the hose 60 in a vacuum state, thereby adsorbing the uppermost printed product on the rubber ring 22.

[0070] Then move the moving rod 110 upward, which can drive the uppermost printed matter to move upward together until the printed matter moves to be flush with the cutting knife 140. Then start the electric push rod 312 to extend the length of the support plate 32 extending out of the support sleeve 31 until the support plate 32 is located below the printed matter and abuts against the printed matter. At this time, the abutting plate 20 moves downward under the action of gravity, and the gravity of several abutting plates 20 is sufficient to press and fix the printed matter on the support plate 32. Then move the mounting rod 150 to drive the cutting knife 140 to slide on the die-cutting box 10, and at the same time start the motor 160 to make the cutting knife 140 cut the printed matter. Finally, lift the abutting plate 20 and then dial the printed matter to make the printed matter fall off the abutting plate 20, so that the cut printed matter all falls on the support plate 32, facilitating the removal of the cut printed matter.

[0071] When cutting the next printed matter, first reset the support plate 32, then move the abutting plate 20 downward to abut against the next layer of printed matter, and repeat the above steps to realize the sequential cutting of the stacked printed matter. It realizes automatic feeding, is convenient to operate, and improves work efficiency.

[0072] The embodiment of the present application also discloses a die-cutting process of a printed matter die-cutting machine.

[0073] A die-cutting process of a printed matter die-cutting machine includes the following steps:

[0074] S1. Stack the printed matter to be cut in the die-cutting box 10. Then move the moving rod 110 downward so that the abutting plate 20 drives the rubber ring 22 to abut against the top wall of the uppermost printed matter. Then move the sliding rod 130 away from the die-cutting box 10, so that the pulling rope 511 pulls the pull rod 51 to move, extract the air in the hose 60, and further adsorb the uppermost printed matter on the rubber ring 22;

[0075] S2. Move the moving rod 110 upward to drive the printed matter to move upward to be flush with the bottom wall of the cutting knife 140. Then start the electric push rod 312 to push the support plate 32 away from the support sleeve 31 until the support plate 32 is located below the printed matter. Remove the force of lifting the moving rod 110, so that the abutting plate 20 presses and fixes the printed matter on the support plate 32 under the action of gravity;

[0076] S3. Then move the mounting rod 150, drive the cutting knife 140 to slide on the die-cutting box 10 and start the motor 160 at the same time to make the cutting knife 140 rotate, so that the cutting knife 140 cuts the printed matter to a specified size;

[0077] S4. Then, use the pull rod 51 to push the piston 50 to reset. The upward movement of the abutting plate 20 toggles the printed matter, causing the rubber ring 22 to separate from the printed matter. Then, start the electric push rod 312 again and continue to push the support plate 32, thereby driving the cut printed matter to move in the direction of the moving hole 12. When the connecting rod 92 moves to the end of the connecting groove 311, the end of the support plate 32 passes through the moving hole 12 and the entire support plate 32 completely moves out of the support sleeve 31. At this time, the support plate 32 rotates downward about the connecting rod 92 under the action of gravity, thereby sending the printed matter on the support plate 32 out of the die-cutting box 10.

[0078] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
