Technical Field

[0001] This utility model relates to the field of die-cutting machine technology, specifically to a debris cleaning mechanism and a die-cutting machine. Background Technology

[0002] When using a laser die-cutting machine to cut irregular materials, traditional laser die-cutting machines use clamps to fix the self-adhesive labels to be cut. For irregular materials such as curved surfaces and wavy shapes, the fixing mechanism is difficult to use. The clamping structure can only fix materials with regular shapes. Irregular materials are prone to displacement due to uneven force. The placement of self-adhesive labels is not convenient enough, and it is impossible to integrate debris cleaning and fixing into one. Therefore, we need to provide a debris cleaning mechanism and a die-cutting machine. Utility Model Content

[0003] The purpose of this utility model is to provide a debris cleaning mechanism and a die-cutting machine. An airflow mechanism is set on the table to place self-adhesive materials on the board. A negative pressure is generated at the top of the board to help adsorb and fix the self-adhesive materials. When it is not necessary to adsorb the self-adhesive materials, the board can be rotated first, and then the top is blown up to help blow the debris off, thus solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a debris cleaning mechanism, comprising: The tabletop, the groove, the plate, and the airflow mechanism are provided. The groove is provided in the tabletop, and the plate is rotatably installed in the groove. The airflow mechanism is provided in the plate to generate air intake and exhaust on the top of the plate, so as to achieve air intake to adsorb and fix the self-adhesive material, and exhaust to clean up the debris on the top of the plate.

The transfer pipe is installed at the bottom of the plate, with its top connected to the main air pipe and its bottom connected to the air frame. A centrifugal fan is connected to one side of the air frame. The centrifugal fan is a small fan, and a protective net is provided at the air inlet end.

[0007] Preferably, the air frame is provided with a filter element, which is used to adsorb and filter the gas generated by laser die cutting, and to intercept impurities and protect the centrifugal fan. The filter element includes a mounting groove, a filter element and a mounting plate.

[0017] 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.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a debris cleaning mechanism, comprising: The table 1, the groove 2, the plate 3 and the airflow mechanism 4 are provided. The groove 2 is opened in the table 1. The plate 3 is rotatably installed in the groove 2. The airflow mechanism 4 is provided in the plate 3 to generate air intake and exhaust on the top of the plate 3, so as to achieve the adsorption and fixation of the self-adhesive material by air intake and the cleaning of debris on the top of the plate 3 by exhaust. Specifically, an airflow mechanism 4 is set on the tabletop 1, which can place the self-adhesive material on the board 3. A negative pressure is generated at the top of the board to help adsorb and fix the self-adhesive material. When it is not necessary to adsorb the self-adhesive material, the board 3 can be rotated first, and then the top is blown up to help blow the debris off. The airflow mechanism 4 is set on the table 1 for processing self-adhesive materials. When adsorbing and fixing, the negative pressure can be applied evenly to the material surface, avoiding deformation and wrinkles caused by uneven local pressure. It has strong adaptability to ultra-thin or flexible self-adhesive materials, which can improve cutting accuracy and reduce scrap rate. At the same time, compared with traditional clamping and fixing, non-contact adsorption does not damage the material surface and protects the structural integrity of the release paper, adhesive layer and other components of the self-adhesive. When cleaning debris, the plate 3 rotates in conjunction with the air blowing design, making the cleaning more efficient and thorough. After rotation, the tilted plate 3 makes it easy for debris to slide off by gravity. The air blowing further enhances the cleaning effect and prevents debris residue from clogging the air holes 41 or adsorption channels, ensuring the long-term stable operation of the airflow mechanism 4.

[0019] The airflow mechanism 4 includes air holes 41, auxiliary air pipes 42, main air pipes 43 and driving components 44. The main air pipe 43 is provided inside the plate body 3. Several auxiliary air pipes 42 are connected to one side of the main air pipe 43. Multiple air holes 41 are connected to the top of the auxiliary air pipes 42. The top of the air holes 41 penetrates the top of the plate body 3. The driving component 44 is installed at the bottom of the plate body 3. The driving component 44 is used to inject gas into the main air pipe 43 and extract gas. Furthermore, the pores 41 are arranged in a matrix on the top surface of the plate 3 to ensure uniform distribution of adsorption force. The plate 3 is made of aluminum alloy, and the internal air pipes are formed by precision CNC machining. The surface is anodized to improve wear resistance. When the drive component 44 draws air, a negative pressure is formed in the main air pipe 43, which is conducted to the pores 41 through the auxiliary air pipe 42 to achieve stable adsorption of thick self-adhesive materials.

[0020] The drive unit 44 includes a transfer pipe 441, an air frame 442 and a centrifugal fan 443. The transfer pipe 441 is installed at the bottom of the plate 3, with its top connected to the main air pipe 43 and its bottom connected to the air frame 442. The centrifugal fan 443 is connected to one side of the air frame 442. The centrifugal fan 443 is a small fan and has a protective net at the air inlet end. It is worth noting that the adapter pipe 441 is connected to the main air pipe 43 and the air frame 442 by a quick-release flange, and a silicone sealing ring is set at the interface to ensure airtightness. The centrifugal fan 443 is a low-noise type (≤65dB), with an air volume of 10-30m³ / h and an air pressure of 500-1500Pa, which meets the requirements of both adsorption and blowing modes. The protective net is made of 304 stainless steel and is installed at the air inlet of the fan to effectively intercept debris and foreign matter.

[0021] The air frame 442 is equipped with a filter element 5. The filter element 5 is used to adsorb and filter the gas generated by laser die cutting, and to intercept impurities and protect the centrifugal fan 443. The filter element 5 includes a mounting groove 51, a filter element 52 and a mounting plate 53. The surface of the air frame 442 is provided with a mounting groove 51 for mounting the filter element 52. The mounting plate 53 is fixedly installed on one side of the filter element 52. It should be noted that the filter element 52 adopts a three-layer composite structure: a primary filter layer of PP cotton, a secondary filter layer of activated carbon, and a high-efficiency filter layer of HEPA. The mounting plate 53 has a nitrile rubber sealing gasket at its edge, which forms an embedded seal with the mounting groove 51 to prevent unfiltered gas from bypassing.

[0022] Two magnetic blocks 6 are fixedly installed on one side of the mounting plate 53, and the air frame 442 is set as a metal frame. Furthermore, the magnetic block 6 uses neodymium iron boron strong magnets with nickel plating for corrosion protection. Magnetic conductive stainless steel sheets are embedded in the corresponding positions of the metal frame to form a closed magnetic circuit with the magnetic block 6, ensuring that the filter element 52 is securely installed and easy to disassemble.

[0023] The bottom of the tabletop 1 is provided with a starter 7, which is used to adjust the rotation of the plate 3. The starter 7 includes a bracket 71 and a cylinder 72. The bracket 71 is fixed to the bottom of the tabletop 1, and the cylinder 72 is hinged to the surface. The extended end of the top of the cylinder 72 is hinged to the bottom of the plate 3. The cylinder 72 is a double-acting type, which ensures that the plate 3 can complete the rotation from 0° (horizontal) to 60° (tilt) within 10 seconds. The cylinder 72 is connected to the bracket 71 and the plate 3 through a fisheye joint.

[0024] A contact plate 8 is fixedly installed on one side of the plate 3, and a baffle strip 9 that fits against the contact plate 8 is fixedly installed on one side of the groove 2. When the top of the contact plate 8 contacts the bottom of the baffle strip 9, the plate 3 is placed horizontally. Furthermore, the contact plate 8 and the baffle strip 9 are made of hard aluminum, and the contact surfaces are ground. A polyurethane buffer pad is attached to the bottom of the baffle strip 9 to reduce the impact noise and wear when the plate 3 is reset.

[0025] A discharge hopper 10 is fixedly installed at the bottom of the table 1. The top of the discharge hopper 10 is connected to the trough 2, and the plate 3 can be rotated into the discharge hopper 10. The bottom of the discharge hopper 10 is sloping. Specifically, the angle of the inclined surface of the discharge hopper 10 is ≥45°, and the inner wall is polished to ensure that the diameter of the debris can slide off on its own. The outlet of the discharge hopper 10 is connected to an external dust collection box.

[0026] A reserved slot 11 for the movement of cylinder 72 is provided on one side of the discharge hopper 10; It is worth noting that the width of the reserved groove 11 is 10-15mm larger than the outer diameter of the cylinder 72, and the height meets the range of motion of the cylinder 72 at its maximum stroke. The edges are rounded with an R5mm radius to prevent scratching the cylinder 72. An accordion-style dust cover made of PVC mesh fabric can be installed in the reserved groove 11. Both ends are fixed with buckles to ensure that debris does not enter the moving area of ​​the cylinder 72.

[0027] A die-cutting machine includes a debris cleaning mechanism. A laser die-cutter 12 and an adjustment table 13 are provided on the top of the table. The laser die-cutter 12 is mounted on the surface of the adjustment table 13. The adjustment table 13 is used to control the multi-directional movement of the laser die-cutter 12. Specifically, the adjustment table 13 adopts an XYZ three-axis linkage structure and is dynamically adjusted by an external PLC controller.

[0028] The centrifugal fan 443, laser die cutter 12, adjustment table 13 and cylinder 72 involved in this application are all implemented using existing mature technologies and are connected to an external PLC controller and power supply. This is a conventional technical means in this field, so their specific circuit connections, control logic and working process will not be described in detail.

[0029] This device places the self-adhesive material to be die-cut on the top of the board 3. The centrifugal fan 443 is activated to extract air from the board 3, allowing external air to enter through multiple air holes 41. The top of the board 3 can adsorb the self-adhesive material, providing auxiliary fixation. The laser die-cutter 12, in conjunction with the adjusting table 13, performs the die-cutting. It also adsorbs some of the fumes generated during laser die-cutting into the board 3, which then enters the air frame 442 through the adapter pipe 441. The fumes are filtered by the filter element 5 in the air frame 442 before being discharged. After cutting, the debris accumulates on the plate 3. The cylinder 72 is started to drive the plate 3 to rotate, and the plate 3 tilts into the discharge hopper 10. The centrifugal fan 443 starts in reverse to supply air into the plate 3. The airflow is discharged through the top of the air hole 41, which helps to blow the debris into the discharge hopper 10. The discharge hopper 10 is inclined, which can guide the debris to be discharged into the external collection bucket. The cylinder 72 has two ends, and the extended end makes the plate 3 horizontally distributed. A contact plate 8 is provided on one side of the plate 3. A baffle strip 9 that fits against the contact plate 8 is provided in the trough 2 to restrict the position of the plate 3.
