Description

Technical Field

[0001] This application relates to the field of printing production technology, specifically a die-cutting device for printing production. Background Technology

[0002] In the existing die-cutting process of printing production, the operation steps are as follows: First, the printed substrates (such as paper, cardboard, etc.) are stacked on the feeding table. The conveying mechanism transports the substrates one by one to the guiding station. The staff adjusts the position of the guiding components to perform preliminary positioning of the substrates. Then, the substrates are transported to the die-cutting station. The die-cutting blades are driven by the drive mechanism to apply downward pressure and cooperate with the pressure plate below to complete the die-cutting of the substrates. After the cutting is completed, the printed products are transported to the receiving area by the unloading mechanism, and the single-segment die-cutting operation is completed.

[0003] However, in the process of cutting the substrate, some existing die-cutting devices usually rely on the single downward pressure of the die-cutting blade assembly to achieve cutting, lacking a clamping structure that can simultaneously apply stable pressure from above the substrate. As a result, when the die-cutting blade assembly contacts the substrate and cuts downward, the substrate is prone to upward warping due to uneven local stress. For example, thin paper or flexible film substrates are prone to edge wrinkles and central bulging. Therefore, it is necessary to provide a die-cutting device for printing production to solve the above problems. Utility Model Content

[0004] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a die-cutting device for printing production, which solves the problem that some existing die-cutting devices lack a clamping structure that applies stable pressure synchronously from above the substrate, resulting in uneven local stress on the substrate during cutting, causing upward warping, edge wrinkles, and central bulging.

[0012] Furthermore, the spring causes the first circular plate and the positioning plate to maintain a downward motion tendency.

[0013] Furthermore, the adjustment assembly includes a transition plate mounted on the intermediate plate, a drive motor mounted on the transition plate, a bidirectional lead screw coaxially mounted on the output end of the drive motor, two sets of bidirectional sliders sleeved on the shaft of the bidirectional lead screw, two sets of sliding grooves opened on the transition plate, and a transition frame that can slide within the sliding groove is mounted on the bidirectional slider.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0030] like Figure 1and Figure 2 As shown, this application provides a die-cutting apparatus for printing production, including a conveying assembly 1 for conveying the substrate and providing material transfer for subsequent die-cutting processes. The conveying assembly 1 includes a conveying frame 11, which serves as a support structure for the entire conveying assembly 1 and provides an installation base for other components.

[0031] A conveyor motor 12 is bolted to one end of the conveyor frame 11. The conveyor motor 12 is the power source for the conveying process. After being powered on, it can drive the relevant components to rotate through the corresponding controller, thereby realizing the conveying of the printed material. The output end of the conveyor motor 12 passes through the conveyor frame 11 and is coaxially mounted with an active roller 13. The active roller 13 rotates under the drive of the conveyor motor 12.

[0032] A driven roller 14 is rotatably connected to the other end of the conveyor frame 11. Two conveyor belts 15 are fitted on the roller bodies of both the driving roller 13 and the driven roller 14. When the driving roller 13 rotates, it drives the conveyor belts 15 fitted on their roller bodies to move through cooperation with the driven roller 14. The two conveyor belts 15 can more stably carry the printing substrate and reduce the offset of the printing substrate during the conveying process.

[0033] like Figures 1 to 3 As shown, a pressure-bearing component 2 is installed on the conveyor frame 11. The pressure-bearing component 2 is used to support the substrate during die cutting and cooperates with the subsequent die cutting components to complete the cutting. The pressure-bearing component 2 includes an assembly plate 21 that is bolted to the conveyor frame 11. The assembly plate 21 provides an installation platform for other components of the pressure-bearing component 2.

[0034] A main electric push rod 22 is bolted to the center of the lower end of the assembly plate 21. After the main electric push rod 22 is powered on, it is started by the corresponding controller to adapt to the die-cutting requirements of substrates of different thicknesses. The output end of the main electric push rod 22 passes through the assembly plate 21 and is bolted to a pressure plate 23. The pressure plate 23 is in direct contact with the substrate and provides a stable support surface for the substrate. Slide rods 24 are bolted to the four corners of the lower part of the pressure plate 23. The slide rods 24 can slide along the body of the assembly plate 21. The slide rods 24 provide guidance for the lifting and lowering of the pressure plate 23, ensuring that the pressure plate 23 remains stable during the lifting and lowering process and is not prone to tilting, thereby ensuring the support stability of the substrate during die-cutting.

[0035] The pressure plate 23 is used to lift the substrate upwards and move it away from the conveyor belt 15. During the substrate cutting process, the pressure plate 23 remains stationary.

[0036] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, a positioning component 3 is installed on the conveyor frame 11. The positioning component 3 can apply stable pressure from above the substrate and assist in positioning. The positioning component 3 includes an assembly frame 31 that is bolted to the conveyor frame 11. The assembly frame 31 provides installation space and support for the various components of the positioning component 3. Two sets of auxiliary electric push rods 32 are bolted to the upper part of the assembly frame 31. The output end of the auxiliary electric push rod 32 passes through the assembly frame 31 and is bolted to an intermediate plate 33. When the auxiliary electric push rod 32 is energized, it can drive the intermediate plate 33 to rise and fall by activating the corresponding controller, thereby moving the positioning part closer to or away from the substrate, realizing the pressing or releasing of the substrate.

[0037] Brackets 34 are bolted to both ends of the intermediate plate 33. Guide rods 35 are slidably connected to both sides of the brackets 34. The guide rods 35 provide guidance for the movement of the positioning component, ensuring that the positioning part can smoothly approach or move away from the substrate, so that the pressure of the positioning part on the substrate is more even. A first circular plate 36 is fixedly installed at one end of the guide rod 35. A positioning plate 37 is bolted to the first circular plate 36. The positioning plate 37 is used to apply pressure to the substrate from above to prevent it from warping during die cutting.

[0038] A second circular plate 361 is fitted onto the other end of the guide rod 35. The second circular plate 361 is bolted to the bracket 34. A spring 362 is fixedly installed on the second circular plate 361. One end of the spring 362 is fixedly connected to the first circular plate 36. The spring 362 keeps the first circular plate 36 and the positioning plate 37 moving downwards. The spring 362 has a buffering effect. When the positioning plate 37 contacts the substrate, the spring 362 can extend and retract to a certain extent according to the thickness of the substrate. This ensures that sufficient pressure is applied to the substrate to prevent warping, and also prevents excessive pressure from damaging the substrate, thus improving the positioning and pressing effect of the substrate.

[0039] The positioning plate 37 is located below the cutting blade 48. During the cutting process of the substrate, the positioning plate 37 first comes into contact with the substrate.

[0040] like Figures 3 to 6As shown, an adjustment assembly 4 is installed on the intermediate plate 33. The adjustment assembly 4 is used to adjust the position of the cutting part to adapt to different die-cutting requirements and improve the versatility of the device. The adjustment assembly 4 includes a transition plate 41 that is bolted to the intermediate plate 33. The transition plate 41 provides an installation platform for other components of the adjustment assembly 4. A drive motor 42 is bolted to one end of the transition plate 41. A bidirectional lead screw 43 is coaxially mounted on the output end of the drive motor 42. Two sets of bidirectional sliders 44 are sleeved on the body of the bidirectional lead screw 43. When the drive motor 42 is powered on and started by the corresponding controller, it drives the bidirectional lead screw 43 to rotate. Under the action of thread engagement, the two sets of bidirectional sliders 44 will move in opposite or the same direction on the bidirectional lead screw 43, thereby realizing position adjustment.

[0041] Two sets of sliding grooves 45 are provided on the adapter plate 41. An adapter frame 46 that can slide in the sliding groove 45 is installed on the bidirectional slider 44. The sliding groove 45 provides a track for the sliding of the adapter frame 46 to ensure the smooth movement of the adapter frame 46. An adjusting plate 47 is installed at one end of the adapter frame 46 by bolts. A cutting blade 48 is installed on the adjusting plate 47 by bolts.

[0042] Specifically, the cutting blade 48 is used to die-cut the substrate. By adjusting the position of the cutting blade 48, substrates of various sizes can be die-cut. Limiting rods 49 are fixedly installed on both sides of the middle plate 33. The adjusting plate 47 can slide on the body of the limiting rod 49. The limiting rod 49 plays a limiting and guiding role in the movement of the adjusting plate 47, ensuring that the adjusting plate 47 remains stable during the movement, thereby ensuring the positional accuracy of the cutting blade 48 and improving the die-cutting quality.

[0043] Working principle: When in use, the substrate to be die-cut is first placed on the conveyor belt 15 of the conveyor assembly 1. Then, the conveyor motor 12 is started. The operation of the conveyor motor 12 drives the drive roller 13 to rotate. The drive roller 13, through cooperation with the driven roller 14, causes the conveyor belt 15 sleeved on their roller bodies to start moving, thereby conveying the substrate to the die-cutting station.

[0044] When the substrate arrives at the die-cutting station, the main electric push rod 22 is powered on and started. Its output end pushes the pressure plate 23 to rise. Under the guidance of the slide rod 24, the pressure plate 23 rises smoothly until it contacts the substrate, providing a stable support surface for the substrate.

[0045] Next, the auxiliary electric push rod 32 is activated. The output end of the auxiliary electric push rod 32 drives the intermediate plate 33 to descend. The positioning plate 37 on the intermediate plate 33 also moves downward. Under the buffering effect of the spring 362, the positioning plate 37 contacts the substrate. The spring 362 applies stable and appropriate pressure to the substrate to prevent the substrate from warping during the subsequent die-cutting process.

[0046] Before starting the auxiliary electric push rod 32, the drive motor 42 is started according to the die-cutting requirements of the substrate. The drive motor 42 drives the bidirectional lead screw 43 to rotate. Under the guidance of the thread engagement, the slide groove 45 and the limit rod 49, the two sets of bidirectional sliders 44 move along the bidirectional lead screw 43. The adjustment plate 47 is moved through the adapter frame 46, thereby adjusting the position of the cutting blade 48 so that it is aligned with the part of the substrate that needs to be die-cut.

[0047] After the position is adjusted, the cutting blade 48 moves downward under the drive of the auxiliary electric push rod 32, and cooperates with the pressure plate 23 to complete the die-cutting of the substrate;

[0048] After die-cutting is completed, the auxiliary electric push rod 32 drives the middle plate 33 to rise, the positioning plate 37 separates from the substrate, the main electric push rod 22 drives the pressure plate 23 to fall and reset, and finally, the conveyor motor 12 continues to run, and the conveyor belt 15 transports the die-cut substrate to the receiving area to complete one die-cutting operation.

[0049] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
