Description

Technical Field

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

[0002] In the field of printing processing technology, die-cutting is a crucial step in the post-processing of printed materials. With the continuous development of the printing industry, the demands for both the quality and production efficiency of printed materials are constantly increasing.

[0003] To improve the wear resistance, water resistance, protection, and aesthetics of printed materials, patches, and decorative patches, they are often laminated before being die-cut into a predetermined shape. However, existing die-cutting equipment has significant shortcomings in practical applications. Residual laminating material remains on the surface of the finished product after die-cutting, and traditional separation methods often rely on manual tearing or simple peeling devices. This method is not only inefficient but also prone to scratches and damage to the finished product surface, affecting product quality. Furthermore, if the residual laminating material is not cleaned up promptly, it may entangle equipment parts during subsequent production, causing equipment malfunctions and reducing production efficiency. In addition, the recycling of the separated finished product and residual laminating material lacks a systematic design, often resulting in mixed storage or random stacking, increasing subsequent sorting costs and hindering material recycling.

[0004] Therefore, it is necessary to propose a new technical solution to address the above problems. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figure 1-2 In this embodiment of the utility model, a die-cutting device for printing production is composed of a frame 1, a feeding assembly 3, a die-cutting assembly 4, a separation assembly 5, a film coating waste recycling assembly 6, and a finished product recycling assembly 7.

[0036] The frame 1 is equipped with a workbench 2, which serves as the supporting foundation for the entire device, bearing and fixing other components. A feeding assembly 3 is installed on the feeding side of the workbench 2 to convey the coated sheet. A die-cutting assembly 4 is positioned on the workbench 2 and along the discharge path of the feeding assembly 3, die-cutting the coated sheet from the feeding assembly 3 into a preset shape. A separating assembly 5 is installed on the discharge side of the workbench 2, along the discharge path of the die-cutting assembly 4, responsible for separating and conveying the die-cut finished product from the coating residue. A coating residue recovery assembly 6 is installed on one side of the upper part of the frame 1, above the separating assembly 5, for recovering the separated coating residue. A finished product recovery assembly 7 is installed on one side of the lower part of the frame 1, below the separating assembly 5, for collecting the separated finished product.

[0037] In one embodiment, the feeding assembly 3 is installed on the feeding side of the workbench 2 for conveying the coated sheet. Its core structure may include an unwinding mechanism and a guiding conveying structure. The unwinding mechanism consists of an unwinding roller and a tension adjusting device. The unwinding roller is mounted on the frame 1 via bearings and connected to a torque motor, and can unwind the sheet into a roll. The tension adjusting device, through a sensor and a damper, controls the sheet conveying tension in real time to prevent slack or stretching deformation. The guiding conveying structure includes multiple sets of parallel guide rollers 14. Some of the guide rollers 14 can be driven by a motor as active rollers, while the rest are driven rollers, which together guide the sheet to be smoothly fed to the die-cutting assembly 4 along a preset path, ensuring accurate conveying direction.

[0038] In one embodiment, the die-cutting assembly 4 is mounted on the worktable 2 and located in the discharge path of the feeding assembly 3, used to die-cut the coated sheet into a preset shape. It mainly consists of a die-cutting tool, a drive unit 12, and a pressure regulating mechanism. The die-cutting tool includes a punch and a die, with the blade profile designed according to the finished product shape. The material is mostly hardened metal to improve wear resistance. The drive unit 12 uses a hydraulic system or an electric push rod, powered by a servo motor or hydraulic pump, to push the punch towards the die to complete the stamping and cutting. The pressure regulating mechanism integrates a pressure sensor and an adjustment knob, which can monitor the die-cutting pressure in real time and adjust it as needed, avoiding abnormal pressure that could damage the sheet or result in incomplete cutting. Some die-cutting assemblies 4 are also equipped with a waste removal structure, which removes cutting debris through air holes or a waste suction device to ensure a clean process.

[0039] The separation assembly 5 includes two first fixed frames 8 installed on the discharge side of the worktable 2, which provide support and mounting positioning for other components of the separation assembly 5. The two first fixed frames 8 are arranged opposite each other to form a stable frame structure, ensuring the stability of the separation assembly 5 during operation.

[0040] The transfer roller 9 is positioned between two first fixed frames 8 and is driven by a drive device 12. The drive device 12 can be a motor, and the output shaft of the motor is connected to the transfer roller 9, providing rotational power to the transfer roller 9. The function of the transfer roller 9 is to transport the die-cut, coated sheets. During rotation, it works in conjunction with appropriate guiding structures or manual methods to achieve the separation and transport of the sheets. The surface of the transfer roller 9 can be specially treated, such as increasing roughness or adding anti-slip textures, to ensure that the sheets do not slip during transport, thus guaranteeing the stability and accuracy of the transport.

[0041] The first pressing structure 10 is arranged circumferentially along the conveyor roller 9 and corresponds to the die-cutting assembly 4, employing an elastic roller pressing structure. This structure includes a roller shaft and an elastic sleeve fitted around the outside of the roller shaft. Both ends of the roller shaft are mounted to the first fixed frame 8 via spring-loaded connectors. The elasticity of the springs allows the first pressing structure 10 to apply a certain pressure to the die-cut, coated sheet, guiding it smoothly into the conveyor roller 9. By adjusting the spring compression, the pressing force of the first pressing structure 10 on the sheet can be controlled to accommodate sheets of different thicknesses and materials. During sheet transport, the first pressing structure 10 also plays a role in flattening the sheet, preventing wrinkles and other defects.

[0042] The second fixed frame 13 is fixed inside the first fixed frame 8 and longitudinally connected to it. The second fixed frame 13 includes an integral fixing part 16 and a connecting part 17. The fixing part 16 has an elongated hole 18, and the inner side of the first fixed frame 8 has a corresponding threaded hole. Bolts or other connecting parts pass through the elongated hole 18 and engage with the threaded hole to connect the second fixed frame 13 to the first fixed frame 8. This connection method allows the installation position of the second fixed frame 13 on the first fixed frame 8 to be finely adjusted along the direction of the elongated hole 18 to adapt to different working requirements. The connecting part 17 has several spaced connecting holes 15 along the longitudinal direction.

[0043] The guide roller 14 is rotatably connected between two second fixed frames 13, and its end is rotatably connected to any of the connecting holes 15. The guide roller 14 can rotate freely around its own axis. When the die-cut sheet is conveyed to the guiding mechanism, the coating waste changes its conveying direction under the action of the guide roller 14 and is guided to the coating waste recycling assembly 6. By selecting different connecting holes 15 to install the guide roller 14, the tilt angle of the guide roller 14 can be adjusted, thereby precisely controlling the guiding direction of the coating waste and ensuring that the coating waste can accurately enter the recycling assembly.

[0044] The second pressing structure 11 corresponds to the finished product recycling component 7 and is also an elastic roller pressing structure. Its structure is similar to the first pressing structure 10, including a roller shaft, an elastic sleeve, and a spring-loaded connector mounted on the first fixed frame 8. The second pressing structure 11 applies pressure to the separated finished product, guiding it to the finished product recycling component 7. During the transfer of the finished product to the recycling component, the second pressing structure 11 further compacts the finished product, maintaining its regular shape for easy subsequent collection and storage. Simultaneously, the elastic structure can adapt to finished products of different thicknesses, ensuring effective guidance and compaction of the finished product.

[0045] The film coating waste recycling assembly 6 is installed on one side of the upper part of the frame 1 and above the separation assembly 5. It includes a first crossbeam 19 connected to one side of the upper part of the frame 1, which supports and secures other components. A film coating waste drive device 20 is mounted on the first crossbeam 19. This drive device 12 can be a motor, and the motor's output shaft is connected to the film coating waste take-up roller 21. The film coating waste drive device 20 drives the film coating waste take-up roller 21 to rotate, thus recycling the film coating waste separated by the separation assembly 5. During the take-up process, the rotational speed and torque of the drive device 12 can be controlled to ensure that the film coating waste is evenly and tightly wound onto the take-up roller, facilitating subsequent processing and resource reuse.

[0046] The finished product recycling assembly 7 is installed on one side of the lower part of the frame 1 and below the separation assembly 5. It includes a second crossbeam 22 connected to the lower part of the frame 1, which provides support for other components of the assembly. A finished product recycling drive device 23, which can also be a motor, is mounted on the second crossbeam 22, with its output shaft connected to the finished product winding roller 24. The finished product recycling drive device 23 drives the finished product winding roller 24 to rotate, collecting the finished product separated by the separation assembly 5. During the collection process, the operating parameters of the drive device 12 can be adjusted according to the characteristics and requirements of the finished product, ensuring that the finished product is neatly and orderly wound onto the finished product winding roller 24, facilitating subsequent handling, storage, and further processing.

[0047] When the die-cut sheet is conveyed to the guiding mechanism, the operator manually separates the coating residue from the finished product (e.g., peels the coating residue off the sheet surface). The separated coating residue, guided by the guide roller 14, changes its conveying direction and is transported along the surface of the guide roller 14 to the coating residue recycling assembly 6. Simultaneously, the separated finished product continues to rotate with the conveyor roller 9. Driven by the conveyor roller 9, the finished product is conveyed to the second pressing structure 11. The second pressing structure 11 applies pressure to the finished product, making it tightly adhere to the surface of the conveyor roller 9, and guides the finished product along a preset path to the finished product recycling assembly 7 located at the lower part of the frame 1. The finished product recycling drive device 23 drives the finished product winding roller 24 to rotate, winding and collecting the finished product.

[0048] During this process, the drive unit 12 of the coating waste recycling component 6 and the drive unit 12 of the finished product recycling component 7 operate synchronously. By controlling the rotation speed of the coating waste take-up roller 21 and the finished product take-up roller 24, a stable tension is formed on the transmission path of the coating waste and the finished product. This tension ensures that the separated coating waste and the finished product are wound up in an orderly manner, avoiding loosening, wrinkling, or entanglement, thus realizing the automated and systematic recycling of materials after die-cutting.

[0049] Through the above design, this utility model has the following beneficial effects:

[0050] Through the synergistic action of the transfer roller 9, the first pressing structure 10, the guiding mechanism and the second pressing structure 11 in the separation component 5, the directional separation and transfer of the die-cut finished product and the film-coated waste material is realized, avoiding the inefficiency and damage problems of traditional manual tearing and improving production efficiency.

[0051] The guide roller 14 of the guide mechanism can be tilted at an adjustable angle through the connection hole 15 of the second fixed frame 13, and the second fixed frame 13 and the first fixed frame 8 can be finely adjusted in position through the long hole 18 and the threaded hole, which can adapt to the separation and guidance requirements of sheets of different specifications and enhance the applicability of the device.

[0052] The film coating waste recycling component 6 and the finished product recycling component 7 are respectively installed on the upper and lower sides of the frame 1 via the first crossbeam 19 and the second crossbeam 22. The drive device 12 drives the winding roller to wind synchronously, realizing the classified recycling of the separated materials and avoiding mixed placement and subsequent sorting costs.

[0053] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
