This allows for the movement and adjustment of the stacked sheet material by the individual advancement of the roller.

Description

Technical Field

[0001] This invention relates to the field of die-cutting machine technology, and more particularly to a digital die-cutting machine without printing plates. Background Technology

[0002] Digital die-cutting technology can cut printed materials or other paper products according to pre-designed graphics using die-cutting plates, thus freeing the printed materials from being limited to straight edges and right angles. Digital die-cutting machines utilize steel blades, metal molds, and steel wire, applying pressure through a printing plate to cut printed materials or cardboard into specific shapes. It is an important piece of equipment for post-printing packaging processing. Plateless die-cutting, also known as plateless die-cutting, is a significant improvement over existing die-cutting mechanisms. It uses the interaction of corresponding dies to die-cut cardboard, cartons, etc., greatly improving die-cutting efficiency. During die-cutting, the sheet material to be processed must be manually placed on a conveyor belt. However, because the placement of the sheet material cannot be completely uniform, partial stacking may occur on the conveyor belt, affecting die-cutting. Traditional conveyor components can only move synchronously and cannot move individually to adjust and separate stacked sheet material, reducing die-cutting efficiency. To address these issues, the applicant proposes a digital plateless die-cutting machine. Summary of the Invention

[0009] Furthermore, the bed frame is provided with a chamber, and a second drive motor is installed in the chamber. The output end of the second drive motor is connected to a rotating shaft via a coupling. The end of the rotating shaft away from the second drive motor is connected to the bed frame via a bearing. Multiple first bevel gears are fixedly sleeved on the rotating shaft at equal intervals, and multiple fourth bevel gears are slidably sleeved on the rotating shaft. The outer wall of the rotating shaft is provided with a groove, and the inner wall of the fourth bevel gear is provided with teeth corresponding to the groove. The teeth and grooves are adapted to each other. A first round shaft passes through the interior of the first roller, and the first roller and the first round shaft are connected by an interference fit. One end of the first round shaft is connected to the bed frame via a bearing, and the other end of the first round shaft is connected to a second bevel gear, which meshes with the first bevel gear.

[0010] Furthermore, the adjusting mechanism includes a second roller, a bearing support, and a vertical plate. A second circular shaft passes through the interior of the second roller, and the second roller and the second circular shaft are interference-fitted. One end of the second circular shaft is connected to a bracket via a bearing, and the other end of the second circular shaft is connected to a third bevel gear. A first guide rod passes through the interior of the bracket, and the bracket and the first guide rod are slidably connected. A rectangular plate is connected to the end of the first guide rod away from the bracket. The bottom of the rectangular plate is fixedly connected to the bottom inner wall of the cavity. A first spring is connected between the bracket and the rectangular plate. A reinforcing rod is connected between the bracket and the bearing support. The reinforcing rod does not interfere with the second roller. One end of the third bevel gear is connected to the bearing support via a bearing, and one end of the fourth bevel gear is connected to the bearing support via a bearing.

[0014] The technical solution provided by this invention has the following advantages compared with known public technologies:

[0015] 1. When the folded plate material is conveyed to the adjustment mechanism area, the plate material in front of the stacked part moves forward with the roller by moving the individual roller, while the plate material behind does not move. This achieves automatic separation of the stacked plate material and allows the roller to move and adjust the stacked plate material by moving forward independently.

[0016] 2. By setting up baffles to deal with different stacking conditions of plate-shaped materials, the baffles can intercept the plate-shaped materials at the rear that are piled up at the front and rear, thus preventing the plate-shaped materials at the rear from moving along with them.

[0017] 3. The auxiliary component corresponding to the moved plate material moves along with it to ensure that the plate material comes into contact with the second roller, thereby driving the plate material to move. Another auxiliary plate presses down the material that overlaps with the moved plate material to prevent it from moving along with it, further ensuring the separation of the two plate materials.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] The present invention will be further described below with reference to embodiments.

[0031] Example: Figure 1-9As shown, this invention provides a digital die-cutting machine without printing plates, including a die-cutting machine body 1, a conveying component 5 disposed at one end of the die-cutting machine body 1, and a sheet-like material. It also includes: an extension plate 2 connected to one side of the top of the die-cutting machine body 1; a connecting plate connected to the bed frame 7 of the conveying component 5 at the end of the extension plate 2 away from the die-cutting machine body 1; a die-cutting area 3 disposed inside the die-cutting machine body 1; a die-cutting head 6 installed above the die-cutting area 3; the material undergoes die-cutting processing through the die-cutting head 6; an output conveyor belt 4 installed at one end of the die-cutting machine body 1; the processed material is transported and discharged through the output conveyor belt 4; the conveying component 5 includes a bed frame 7; two sets of scanning mechanisms for detecting paperboard are installed on both sides of the top of the bed frame 7; the scanning mechanisms have the function of scanning and processing sheet-like materials. The system identifies stacked, overlapping plate-shaped materials. Two sets of scanning mechanisms are a first scanner 8 and a second scanner 9, which are symmetrically arranged. Two blocking components 10 for intercepting plate-shaped materials are symmetrically installed on both sides of the bed frame 7. Two auxiliary components 11 for pressing down the plate-shaped materials are arranged on the top of the bed frame 7. The bed frame 7 is equipped with a first roller 30 and an adjustment mechanism 36 for adjusting the spacing of the plate-shaped materials. The adjustment mechanism 36 has several components and includes at least one processor and a memory that communicates with at least one processor. The memory has instructions that can be executed by at least one processor. The instructions are executed by at least one processor so that at least one processor can execute any of the intelligent devices of the scanning mechanism, the blocking component 10, the auxiliary component 11 and the adjustment mechanism 36.

[0032] The bottom of the extension plate 2 is symmetrically provided with rectangular slots 19. There are two rectangular slots 19, and two first drive motors 20 are installed inside the extension plate 2. The rectangular slots 19 are provided with threaded rods 21 and connecting blocks 22. The threaded rods 21 pass through the interior of the connecting blocks 22 and are threadedly connected to the connecting blocks 22. The connecting blocks 22 are adapted to the rectangular slots 19. One end of the threaded rods 21 passes through the rectangular slots 19 and is connected to the first drive motors 20 through a coupling. When the first drive motors 20 are started, they can drive the connecting blocks 22 to move within the rectangular slots 19.

[0033] By adopting the above technical solution, the auxiliary component 11 includes a telescopic rod 12 and an auxiliary plate 16. The top of the telescopic rod 12 is connected to the bottom of the connecting block 22. The movement of the connecting block 22 can drive the auxiliary component 11 to move, so that the auxiliary component 11 moves and stops at an appropriate position. The other end of the telescopic rod 12 is connected to a top plate 13. A pressure sensor 14 is installed between the telescopic rod 12 and the top plate 13. The pressure sensor 14 is set with a rated pressure value to prevent the auxiliary component 11 from being subjected to excessive force on the plate-shaped material, causing deformation of the plate-shaped material. The edge of the plate 13 is connected to a slider 18, and the inner wall of the auxiliary plate 16 is provided with a groove 17. The top plate 13 is located on the auxiliary plate 16, and the slider 18 is slidably connected to the groove 17. A spring plate 15 is provided between the auxiliary plate 16 and the top plate 13. When the telescopic rod 12 extends downward and the pressure of the auxiliary plate 16 in contact with the plate material reaches the rated value of the pressure sensor 14, the telescopic rod 12 stops extending downward. The spring plate 15 provides a rebound space between the auxiliary plate 16 and the top plate 13 to prevent the plate material from being deformed due to excessive force.

[0034] The blocking component 10 includes a housing 23 and a rotating rod 24. One end of the rotating rod 24 is provided with a first gear 27, and the other end of the rotating rod 24 is connected to a reinforcing plate 25. A baffle 26 is connected to the reinforcing plate 25. The height of the baffle 26 is slightly larger than the height of a single plate-shaped material on the bed frame 7. A first electric cylinder 28 is installed inside the housing 23. The output end of the first electric cylinder 28 is connected to a first rack plate 29. The end of the rotating rod 24 with the first gear 27 passes through the housing 23, and the rotating rod 24 is rotatably connected to the housing 23. Next, the first gear 27 meshes with the first rack plate 29. When the rotating rod 24 rotates, the rotation angle of the baffle 26 is 90°. When the blocking component 10 is not working, the baffle 26 is parallel to the bed frame 7. After the blocking component 10 is triggered, the baffle 26 is perpendicular to the bed frame 7. The first electric cylinder 28 works to drive the baffle 26 to rotate 90°, so that the baffle 26 surrounds the front of the two stacked plate materials, preventing the rear plate material from moving synchronously with the front plate material.

[0035] By adopting the above technical solution, a chamber is provided inside the bed frame 7, and a second drive motor 32 is installed inside the chamber. The output end of the second drive motor 32 is connected to a rotating shaft 33 via a coupling. The second drive motor 32 drives the rotating shaft 33 to rotate. The end of the rotating shaft 33 away from the second drive motor 32 is connected to the bed frame 7 via a bearing. A plurality of first bevel gears 34 are fixedly sleeved at equal intervals on the rotating shaft 33, and a plurality of fourth bevel gears 46 are slidably sleeved on the rotating shaft 33. A groove 42 is opened on the outer wall of the rotating shaft 33, and the inner wall of the fourth bevel gears 46 is provided with... The tooth corresponding to the groove 42 is adapted to the groove 42. The first round shaft 31 runs through the inside of the first roller 30 and is interference-fitted with the first round shaft 31. One end of the first round shaft 31 is connected to the bed frame 7 through a bearing, and the other end of the first round shaft 31 is connected to the second bevel gear 35. The second bevel gear 35 meshes with the first bevel gear 34. When the rotating shaft 33 rotates, the first roller 30 rotates synchronously. The plate-shaped material is placed on the first roller 30 at the end of the bed frame 7 away from the die-cutting machine body 1 and fed to the die-cutting machine body 1.

[0036] The adjusting mechanism 36 includes a second roller 37, a bearing support 44, and a vertical plate 49. A second circular shaft 38 passes through the interior of the second roller 37, and the second roller 37 and the second circular shaft 38 are interference-fitted. One end of the second circular shaft 38 is connected to a bracket 39 via a bearing, and the other end of the second circular shaft 38 is connected to a third bevel gear 45. A first guide rod passes through the interior of the bracket 39, and the bracket 39 and the first guide rod are slidably fitted together. A rectangular plate 40 is connected to the end of the first guide rod away from the bracket 39. The bottom of the rectangular plate 40 is fixedly connected to the bottom inner wall of the cavity. The bracket 39 and the rectangular plate 40... A first spring 41 is connected between the bracket 39 and the bearing support 44. A reinforcing rod 43 is connected between the bracket 39 and the bearing support 44. The reinforcing rod 43 and the second roller 37 do not interfere with each other. One end of the third bevel gear 45 is connected to the bearing support 44 through a bearing. One end of the fourth bevel gear 46 is connected to the bearing support 44 through a bearing. The third bevel gear 45 and the fourth bevel gear 46 are connected by meshing. The rotation of the fourth bevel gear 46 drives the third bevel gear 45 and the second roller 37 to rotate. When the fourth bevel gear 46 slides on the rotating shaft 33 through the groove 42, the second roller 37, the bracket 39 and the bearing support 44 are moved synchronously.

[0037] By adopting the above technical solution, a roller 48 is rotatably connected to the lower part of the bearing support 44, and a second guide rod is connected to the vertical plate 49. The second guide rod is slidably connected to the bearing support 44, and a second spring 47 is connected between the vertical plate 49 and the bearing support 44. When the second roller 37 moves, the first guide rod and the second guide rod slide synchronously in the bracket 39 and the bearing support 44 respectively to enhance the stability of the second roller 37. At the same time, the first spring 41 and the second spring 47 are stretched, and the vertical plate 49 is connected to the rotating shaft 33 through a gap. A shaft 50 passes through the lower part of the vertical plate 49, and the vertical plate 49 is rotatably connected to the shaft 50. A cam is connected to one end of the shaft 50. 51, and the other end of the shaft 50 is connected to the second gear 52. The bottom of the second gear 52 is meshed with the second rack plate 54. One end of the second rack plate 54 is equipped with the second electric cylinder 53. The second rack plate 54 is connected to the output end of the second electric cylinder 53. The bottom of the vertical plate 49 is connected to the bottom inner wall of the cavity. The vertical plate 49 is fixed. The second electric cylinder 53 is started to drive the cam 51 to rotate, so that the cam 51 turns and squeezes the roller 48, causing the bearing support 44 and the second roller 37 to move. At the same time, the fourth bevel gear 46 slides on the rotating shaft 33, so that the movement and adjustment of a single roller can be realized, and some rollers can move forward independently to move and adjust a single plate material.

[0038] Cam 51 corresponds to and is adapted to roller 48. Bearing support 44, vertical plate 49, bracket 39 and rectangular plate 40 are all inside the cavity. The bottom of bearing support 44 is connected to a first guide block, and a first guide groove is provided below bearing support 44 to slide and engage with the first guide block. The bottom of bracket 39 is connected to a second guide block, and a second guide groove is provided below bracket 39 to slide and engage with the second guide block. When bearing support 44 and bracket 39 move, the first guide block at the bottom of bearing support 44 and the second guide block at the bottom of bracket 39 slide synchronously in the first guide groove and the second guide groove, respectively, so that the second roller 37 has good stability when moving.

[0039] By adopting the above technical solution, the blocking component 10 is located between the first scanner 8 and the second scanner 9, and between the two auxiliary components 11. When the plate-shaped material is conveyed on the conveying component 5 and passes through the first scanner 8, after the first scanner 8 identifies the stacked plate-shaped material, the processor controls the first electric cylinder 28, the first drive motor 20, the second drive motor 32, the telescopic rod 12, and the second electric cylinder 53 to stop the second drive motor 32 from working and stop the first roller 30 and the second roller 37 from rotating. The baffle 26 pops out to intercept the plate-shaped material that is in the upper position at the rear of the two stacked plate-shaped materials, preventing the rear plate-shaped material from moving. When the scanning mechanism identifies that the tail of the front plate-shaped material is above the head of the rear plate-shaped material, the baffle 26 is not triggered. Then, the two telescopic rods 12 extend downward to the auxiliary plate 16 to contact the front and rear plate-shaped materials and generate a certain pressure. Subsequently, the corresponding adjustment mechanism 36 is adjusted. The second roller 37 moves in the direction of the die-cutting area 3. While the second roller 37 moves the sheet material, the auxiliary component 11 corresponding to the sheet material in front moves synchronously with the second roller 37 to ensure that the sheet material and the second roller 37 make contact and move the sheet material. The auxiliary plate 16 corresponding to and in contact with the sheet material behind presses down the sheet material behind to prevent it from moving. This separates the two partially overlapping sheet materials. If one movement of the second roller 37 on the adjusting mechanism 36 is not enough to achieve the separation effect, the second roller 37 is moved repeatedly until the two sheet materials are completely separated. After the overlapping sheet materials are separated, the conveying component 5 resumes its work and continues to convey and feed the sheet material, so that the sheet material continues to be conveyed in the direction of the die-cutting area 3. The second electric cylinder 53 drives the cam 51 and the second roller 37 to reset. The second roller 37 continues to rotate while resetting, without interfering with the continued transmission of the sheet material behind.

[0040] The second roller 37 is located between the second scanner 9 and the blocking component 10. The intelligent devices include, but are not limited to, the first scanner 8 and the second scanner 9 in the scanning mechanism; the intelligent devices include, but are not limited to, the first electric cylinder 28 in the blocking component 10; the intelligent devices include, but are not limited to, the first drive motor 20 and the pressure sensor 14 in the auxiliary component 11; the control motor or cylinder in the telescopic rod 12; the intelligent devices include, but are not limited to, the second electric cylinder 53 in the adjusting mechanism 36; and the intelligent devices include, but are not limited to, the second drive motor 32 in the bed frame 7.

[0041] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

A first roller (30) and an adjustment mechanism (36) for adjusting the spacing of plate-shaped materials are provided on the bed frame (7). The blocking component is located between the first and second scanners, and also between two auxiliary components. When the sheet material is conveyed on the conveying component and passes the first scanner, after the first scanner identifies the stacked sheet material, the processor controls the first electric cylinder, the first drive motor, the second drive motor, the telescopic rod, and the second electric cylinder to stop the second drive motor from working, causing the first and second rollers to stop rotating. The baffle pops out to intercept the sheet material that is at the rear of the two stacked sheet materials, preventing the rear sheet material from moving. If the scanning mechanism identifies that the tail of the front sheet material is above the head of the rear sheet material, the baffle is not triggered. Then, the two telescopic rods extend downward to the auxiliary plate to contact the front and rear sheet materials and generate a certain pressure.

The auxiliary plate corresponding to and in contact with the sheet material behind presses down the sheet material behind, preventing it from moving with the roller. This separates the two partially overlapping sheet materials. If one movement of the second roller on the adjusting mechanism does not achieve the separation effect, the second roller is moved again until the two sheet materials are completely separated. After the overlapping sheet materials are separated, the conveying component resumes operation and continues to convey and feed the sheet material towards the die-cutting area. The second electric cylinder drives the cam and the second roller to reset. The second roller continues to rotate while resetting, without interfering with the continued transmission of the sheet material behind.
