[0037] Embodiment 2:

[0038] like Figure 1-Figure 14 As shown, the present invention mainly includes a frame 1, a support plate 2, a first conveying mechanism, a second conveying mechanism and a driving device 5. The frame 1 is the basic supporting structure of the entire die-cutting machine and is made of high-strength steel to ensure the stability of the entire machine. The support plate 2 is fixed to the frame 1 by bolts for mounting other components. The first conveying mechanism and the second conveying mechanism both adopt a belt transmission system, which are respectively located at the feed end and the discharge end of the frame 1. The driving device 5 adopts a variable frequency motor, which is connected to the crankshaft 12 through a reducer.

[0039] The pressing platform 7 is fixedly mounted on the carrier plate 2 through a fine adjustment mechanism 6. The pressing platform 7 can be finely adjusted in the vertical direction to adapt to the surface adhesive material strips of different thicknesses. The surface of the pressing platform 7 is hardened and has good wear resistance and flatness.

[0040] The carrier plate 2 is fixedly mounted with a support plate 8, which is made of steel and has high strength. The support plate 8 is movably mounted with a press frame 10 through a sliding assembly 9. The sliding assembly 9 includes a linear guide rail and a slider to ensure the smooth up and down movement of the press frame 10. The press frame 10 is made of high-strength alloy steel and is fixedly mounted with a cutter die 11. The cutter die 11 is made of steel, which has been heat-treated and precision-processed, and has sharp cutting edges and durability. According to production requirements, cutter dies 11 of different specifications can be replaced to facilitate cutting and producing surface adhesive material sheets of different sizes.

[0041] The bearing plate 2 is movably mounted with a crankshaft 12, which is made of high-quality alloy steel and has a quenched surface to improve wear resistance and service life. The crankshaft 12 is driven and connected to the press frame 10 through a linkage assembly 13. The linkage assembly 13 can convert the rotational motion of the crankshaft 12 into the reciprocating motion of the press frame 10. The driving device 5 is connected to the crankshaft 12 through a belt drive to provide continuous and stable power output.

[0042] The second conveying mechanism is fixedly installed with a film coating mechanism 14 and a material cutting mechanism 15. The film coating mechanism 14 can evenly cover the protective film on the cut surface adhesive material sheet. The material cutting mechanism 15 is located after the film coating mechanism 14 and is used to cut the continuous surface adhesive material strip into sheets of predetermined length.

[0043] The first conveying mechanism is fixedly provided with a waste discharge mechanism 45. The waste discharge mechanism 45 is used for automatically peeling off and collecting the upper film of the surface adhesive material belt, so as to facilitate the cutting die 11 to cut the surface adhesive material belt.

[0044] In actual operation, the adhesive material strip on the surface of the raw material is first transported by the first conveying mechanism, and at the same time, the waste discharge mechanism 45 peels off the upper protective film of the adhesive material strip on the surface of the raw material. Subsequently, the adhesive material strip with the protective film removed enters the area of ​​the press table 7. The driving device 5 drives the crankshaft 12 to rotate, and the press frame 10 reciprocates up and down through the linkage assembly 13. When the press frame 10 is pressed down, the knife die 11 cuts the adhesive material strip on the surface, quickly forming it in one time to form an adhesive material sheet of a predetermined shape. The cut adhesive material sheet is transported to the coating mechanism 14 by the second conveying mechanism, and a new protective film is covered on the surface. Finally, the cutting mechanism 15 cuts the continuous adhesive material strip on the surface into finished sheets of specified length.

[0045] Embodiment three:

[0046] like Figure 1-Figure 14As shown, the fixing mechanism 16 of the present invention includes a first cylinder 17 and an assembly plate 18, and the first cylinder 17 drives the assembly plate 18. The assembly plate 18 is fixedly installed with a snap-on plate 19, and the snap-on plate 19 is used to abut and fix the cutting die 11. In the specific implementation process, the fixing mechanism 16 is symmetrically installed on both sides of the press frame 10. The first cylinder 17 uses a double-acting cylinder, the cylinder body is fixed on the press frame 10, and the cylinder piston rod is connected to the assembly plate 18. The assembly plate 18 is a metal plate. One side of the assembly plate 18 is fixedly connected to the cylinder piston rod, and the other side thereof is fixedly installed with a snap-on plate 19. The snap-on plate 19 is fixedly installed on the lower surface of the assembly plate 18. Under the action of the first cylinder 17, the snap-on plate 19 fixes the cutting die 11 on the press frame 10 to prevent the cutting die 11 from being displaced during the cutting process. When the cutter die 11 needs to be removed, the control system sends a signal to the first cylinder 17, and the cylinder piston rod extends to push the assembly plate 18 downward, so that the buckle plate 19 is separated from the cutter die 11, and the operator can easily remove the cutter die 11. When installing a new cutter die 11, the cutter die 11 is placed at a preset position on the press frame 10, and then the first cylinder 17 is controlled to retract the piston rod so that the buckle plate 19 tightly presses the edge of the cutter die 11 and fixes the cutter die 11 on the press frame 10. The fixing mechanism 16 is also equipped with a safety interlock device. Only when the assembly plate 18 is completely closed and the cutter die 11 is correctly fixed, the die-cutting machine can start the cutting operation. This design effectively prevents safety accidents and processing quality problems that may be caused by improper fixing of the cutter die 11. The design of the fixing mechanism 16 greatly improves the efficiency and convenience of replacing the cutter die 11. The operator can complete the disassembly and assembly of the cutter die 11 without using tools, which reduces downtime and improves production efficiency. At the same time, the pneumatically controlled fixing method ensures the consistency and stability of each installation, which is conducive to maintaining the stability of processing quality. It not only simplifies the operating process and improves production efficiency, but also enhances the flexibility and adaptability of the entire die-cutting machine, enabling it to quickly respond to different production needs and carry out flexible production of multiple varieties and small batches.

[0047] Embodiment 4:

[0048] like Figure 1-Figure 14As shown, the coating mechanism 14 of the present invention includes a first fixed frame 20, a film material roller shaft 21 and a rolling roller shaft 22. The first fixed frame 20 is fixedly installed with the film material roller shaft 21, and the first fixed frame 20 is fixedly installed with the rolling roller shaft 22 through an adjustment component. The adjustment component can adjust the pressure of the rolling roller shaft 22, and the rolling roller shaft 22 puts the protective film close to the surface adhesive material sheet. In the specific implementation process, the coating mechanism 14 is installed on the second conveying mechanism, which is located after the cutting station. The first fixed frame 20 adopts a welded steel structure, which is surface treated to prevent rust and has sufficient strength and rigidity to support the entire coating system. A plurality of mounting holes and slide grooves are provided on the fixed frame to facilitate the installation and adjustment of various components. The film material roller shaft 21 is installed on the upper part of the first fixed frame 20. Bearings 41 are installed at both ends of the film material roller shaft 21 to ensure smooth rotation. A tension adjustment device is provided on the roller shaft, which can adjust the appropriate unwinding tension according to the protective film of different specifications to prevent wrinkles or bubbles from occurring during the coating process. The rolling roller 22 is installed at the lower part of the first fixed frame 20, directly below the film material roller 21. The rolling roller 22 is made of a hard rubber-coated metal core shaft, and the surface has appropriate elasticity and friction coefficient to ensure that the protective film can be evenly and tightly attached to the surface of the surface adhesive material sheet. The two ends of the rolling roller 22 are connected to the first fixed frame 20 through an adjustment assembly. The adjustment assembly consists of a precision screw, a spring 44 and an adjustment knob. One end of the precision screw is connected to the bearing 41 seat of the rolling roller 22, and the other end passes through the threaded hole on the fixed frame. During operation, the protective film is drawn out from the film material roller 21, bypasses the guide roller and enters the contact area between the rolling roller 22 and the surface adhesive material sheet. The second conveying mechanism drives the cut surface adhesive material sheet to move forward, and at the same time, the rolling roller 22 presses the protective film evenly on the surface of the surface adhesive material sheet under pressure. The roller 22 is driven by the movement of the surface sticky material sheet, which avoids the speed mismatch problem that may be caused by active drive. In order to adapt to the surface sticky material sheets of different thicknesses and materials, the adjustment component allows the operator to adjust the height of the roller 22 according to actual needs. The laminating mechanism 14 is also equipped with an anti-static device, including an ion fan and a grounding conductive device, which effectively eliminates static electricity that may be generated during the laminating process, prevents dust adsorption and wrinkles of the protective film. At the same time, the entire laminating area is enclosed with a transparent protective cover to maintain a clean operating environment and protect the operator's safety.

[0049] Embodiment five:

[0050] like Figure 1-Figure 14As shown, the material cutting mechanism 15 of the present invention includes a material cutting mechanism 24 and a clamping mechanism 25. The material cutting mechanism 24 is composed of a second fixed frame 26, a first motor 27 and a moving platform 28. The second fixed frame 26 is made of aluminum alloy profiles, has good strength and lightweight characteristics, and is fixed to the frame 1 of the die-cutting machine by bolts. The first motor 27 is a servo motor with precise speed and position control capabilities, and is fixedly mounted on the second fixed frame 26. The moving platform 28 is composed of high-precision linear guides and sliders to ensure smooth movement during the cutting process.

[0051] The first motor 27 drives the moving platform 28 to move through the screw rod, converting the rotational motion of the motor into the linear motion of the moving platform 28. A cutter 29 is fixedly mounted on the moving platform 28. The cutter 29 is made of steel and has excellent hardness and wear resistance after a special heat treatment process. The installation of the cutter 29 adopts a quick replacement mechanism for easy maintenance and replacement.

[0052] Before cutting begins, the clamping mechanism 25 first clamps the surface adhesive material strip to prevent the material from moving or deforming during the cutting process. After the clamping is completed, the first motor 27 is started to drive the moving table 28 to move horizontally through the screw rod. The moving table 28 drives the cutter 29 to smoothly and quickly pass through the surface adhesive material strip to achieve precise cutting. The travel limit of the moving table 28 is controlled by a photoelectric switch to prevent mechanical damage caused by overtravel.

[0053] In order to further improve the cutting accuracy, a linear grating ruler is installed on the moving table 28 to feed back the position information of the moving table 28 to the control system in real time. The control system adjusts the motor speed in real time according to the feedback information to ensure the accuracy of the cutting position.

[0054] The working process of the cutting mechanism 15 is as follows: First, the surface adhesive material strip is transported to the cutting position after being processed in the previous process. The clamping mechanism 25 is activated to firmly press the surface adhesive material strip on the cutting platform. Then, the control system issues an instruction, and the first motor 27 starts, driving the moving table 28 and the cutter 29 to move horizontally. The cutter 29 cuts through the surface adhesive material strip at a constant speed to form a smooth incision. After the cutting is completed, the moving table 28 returns to the initial position, the clamping mechanism 25 is released, and the cut surface adhesive material sheet is transported to the next process.

[0055] The entire cutting process is managed by the PLC control system, which can automatically adjust cutting parameters such as cutting speed and clamping force according to different specifications of products. The operator inputs the required product specifications through the human-machine interface, and the system can automatically complete the corresponding parameter settings and adjustments, greatly improving production efficiency and flexibility.

[0056] Embodiment six:

[0057] like Figure 1-Figure 14 As shown, the clamping mechanism 25 of the present invention is an important component of the material cutting mechanism 15, which mainly includes a second cylinder 30, a first pressing plate 31 and a second pressing plate 32. These components work together to ensure that the surface adhesive material belt remains stable during the cutting process, thereby improving the cutting accuracy and product quality.

[0058] The second cylinder 30 is a double-acting cylinder. The cylinder body is made of aluminum alloy, which is lightweight and corrosion-resistant. The piston rod of the cylinder is made of high-strength alloy steel, and the surface is hardened to improve wear resistance and service life. The stroke and thrust of the cylinder are accurately calculated to meet the compression requirements of adhesive material strips with different thicknesses. The air inlet and exhaust ports of the cylinder are connected to solenoid valves, and the telescopic action of the cylinder is controlled by the PLC control system.

[0059] The first pressing plate 31 is connected to the piston rod of the second cylinder 30, and moves up and down through the telescopic movement of the cylinder. The first pressing plate 31 is made of high-strength steel. The surface of the pressing plate is precisely processed to ensure the flatness of the contact surface with the surface adhesive material strip. The size of the first pressing plate 31 is slightly larger than the width of the surface adhesive material strip to be cut to ensure the clamping effect. The first pressing plate 31 is provided with a cutting groove 33, the width of which is slightly larger than the thickness of the cutter 29, allowing the cutter 29 to pass smoothly, preventing the cutter 29 from rubbing against the cutting groove 33, and avoiding the cutter 29 from being worn.

[0060] The second pressing plate 32 is located directly below the first pressing plate 31 and is fixedly mounted on the frame 1 of the die-cutting machine. The second pressing plate 32 is made of high-strength alloy steel, and the surface is mirror-polished to reduce friction with the sticky material strip on the surface. The flatness and hardness of the second pressing plate 32 directly affect the cutting quality, so precision processing technology is used in the manufacturing process to ensure that its surface flatness reaches the micron level.

[0061] In the actual working process, when the surface adhesive material strip is conveyed to the designated cutting position, the PLC control system first issues a command to drive the second cylinder 30 to retract. The second cylinder 30 pushes the first pressing plate 31 to move downward, pressing the surface adhesive material strip against the second pressing plate 32. The pressing force is controlled by adjusting the air pressure of the cylinder to adapt to surface adhesive material strips of different thicknesses and hardnesses.

[0062] After the pressing is completed, the cutter 29 starts to move. The cutter 29 passes through the cutting groove 33 on the first pressing plate 31 and accurately cuts the surface adhesive material strip. Since the surface adhesive material strip is firmly pressed between the first pressing plate 31 and the second pressing plate 32, the surface adhesive material strip will not move or deform during the cutting process, ensuring the flatness and accuracy of the cut.

[0063] After the cutting is completed, the PLC control system issues a command to drive the second cylinder 30 to retract. The first pressing plate 31 rises to release the cut surface adhesive material sheet. Subsequently, the conveying mechanism conveys the cut surface adhesive material sheet to the next process, and at the same time moves the new uncut part to the cutting position to prepare for the next cutting operation.

[0064] Embodiment seven:

[0065] like Figure 1-Figure 14 As shown, the fine adjustment mechanism 6 of the present invention is one of the key components in the die cutting machine, which is used to accurately adjust the height of the press table 7 to adapt to the surface adhesive material with different thicknesses. The fine adjustment mechanism 6 includes a second motor 34, a first inclined top 35 and a second inclined top 36. The second motor 34 is fixedly installed with the carrier plate 2, and adopts a stepper motor or a servo motor, which can provide precise rotation control. The output shaft of the motor is connected to the screw rod, and the rotational motion is converted into linear motion through the screw rod nut mechanism.

[0066] The first inclined top 35 is movably mounted on the carrier plate 2 via a slide rail 37. The slide rail 37 adopts a high-precision linear guide rail to ensure that the first inclined top 35 maintains good straightness and stability during movement. The bottom of the first inclined top 35 is connected to the screw nut, and the top forms an inclined surface.

[0067] The second inclined top 36 is fixedly connected to the press table 7. The bottom of the second inclined top 36 also forms an inclined surface that matches the top of the first inclined top 35. The two inclined surfaces contact each other to form a wedge-shaped mechanism.

[0068] The second motor 34 is connected to the first inclined top 35. When the second motor 34 is running, the first inclined top 35 is driven to move horizontally on the slide rail 37 through the screw nut mechanism. Due to the wedge structure between the first inclined top 35 and the second inclined top 36, the horizontal movement of the first inclined top 35 is converted into the vertical movement of the second inclined top 36.

[0069] The first inclined top 35 is movably connected to the second inclined top 36. The contact surface between the two inclined tops is precisely machined and hardened to reduce friction and improve wear resistance. At the same time, a lubrication system is also provided between the two inclined tops to ensure stability and reliability during long-term operation.

[0070] The working process of the fine adjustment mechanism 6 is as follows: when the height of the press table 7 needs to be adjusted, the control system sends a command to the second motor 34. The second motor 34 rotates a specific angle according to the command, and drives the first inclined top 35 to move in the horizontal direction through the screw nut mechanism. The movement of the first inclined top 35 is converted into the vertical movement of the second inclined top 36 through the wedge structure, thereby realizing the lifting and lowering of the press table 7.

[0071] The press platform 7 of the present invention is fixedly installed with a guide rod 43, and the guide rod 43 is made of steel material. One end of the guide rod 43 is fixed to the bottom of the press platform 7 by a thread, and the other end passes through a through hole pre-processed on the support plate 2. The surface of the guide rod 43 is chrome-plated to improve wear resistance and rust resistance. A spring 44 is installed between the guide rod 43 and the support plate 2. The upper end of the spring 44 contacts the bottom of the press platform 7, and the lower end contacts the upper surface of the support plate 2 to form an elastic abutment. Through the cooperation of the spring 44 and the guide rod 43, the press platform 7 is always pressed against the fine-tuning mechanism 6, so that the fine-tuning mechanism 6 and the press platform 7 form a stable active connection relationship, which is convenient for the fine-tuning mechanism 6 to adjust the height of the press platform 7.

[0072] Embodiment eight:

[0073] like Figure 1-Figure 14 As shown, the linkage assembly 13 of the present invention can convert the rotational motion of the crankshaft 12 into the reciprocating motion of the press frame 10, thereby realizing the precise cutting of the surface adhesive material strip. The linkage assembly 13 is mainly composed of a connecting plate 38 and a movable part 39. The connecting plate 38 is made of high-strength alloy steel material and has good rigidity and fatigue resistance. One end of the connecting plate 38 is connected to the movable part 39 through a shaft 40, and the other end is fixedly connected to the press frame 10. The shaft 40 is made of alloy steel that has been quenched and tempered, and the surface is hardened to improve wear resistance and service life.

[0074] The movable part 39 is a key component in the linkage assembly 13, and is movably connected to the crankshaft 12 through the bearing 41. The bearing 41 is a precision spherical roller bearing 41, which can withstand a large radial load and has a certain automatic self-aligning ability, and can compensate for small installation errors and shaft flexural deformation.

[0075] The connecting plate 38 is movably connected to the movable member 39 via the shaft 40. This connection allows the connecting plate 38 to rotate slightly around the shaft 40, thereby converting the circular motion of the crankshaft 12 into the linear reciprocating motion of the press frame 10. High-precision bearings 41 are used at the connection between the shaft 40, the connecting plate 38 and the movable member 39 to reduce friction and wear.

[0076] The crankshaft 12 is made of high-quality alloy steel, and is subjected to quenching and tempering and precision machining to ensure high strength and dimensional accuracy. The eccentric portion of the crankshaft 12 is connected to the movable member 39 through a bearing 41, and the eccentricity determines the movement stroke of the press frame 10. By replacing the crankshaft 12 with different eccentricities, the cutting depth and stroke can be adjusted to meet different processing requirements.

[0077] During operation, the driving device 5 drives the crankshaft 12 to rotate. The rotation of the crankshaft 12 drives the movable member 39 to make a circular motion, and this motion is converted into an up and down reciprocating motion of the press frame 10 through the connecting plate 38. When the press frame 10 moves downward, the cutting die 11 fixed on the press frame 10 cuts the surface adhesive material tape; when the press frame 10 moves upward, a cutting cycle is completed and preparations are made for the next cutting.

[0078] Embodiment nine:

[0079] like Figure 1-Figure 14 As shown, the waste discharge mechanism 45 of the present invention includes a third fixed frame 46, a recovery roller 47 and a flattening roller 48. The fixed frame is fixed to the frame 1 by bolts and is located above the first conveying mechanism. The surface of the recovery roller 47 is anodized to increase wear resistance and rust resistance. Both ends of the recovery roller 47 are mounted on the third fixed frame 46 through bearings 41. The length of the flattening roller 48 is the same as that of the recovery roller 47. The surface of the flattening roller 48 is coated with a layer of silicone. This design can provide sufficient pressure for the surface adhesive material belt without causing damage to its surface. The flattening roller 48 is mounted on the third fixed frame 46 through an adjustable bracket, which allows the flattening roller 48 to be adjusted in the vertical direction to adapt to surface adhesive material belts of different thicknesses. A third motor 49 is fixedly mounted on the third fixed frame 46. The third motor 49 is a servo motor. The motor is connected to the recovery roller 47 through a reducer. When rolling up the upper protective film of the surface sticky material, the material head of the protective film is fixed on the recovery roller 47, and the third motor 49 drives the recovery roller 47 to rotate so that the protective film is rolled up and recovered. In this process, the rotation speed of the recovery roller 47 matches the conveying speed of the surface sticky material belt.

[0080] Embodiment ten:

[0081] like Figure 1-Figure 14 As shown, the frame 1 of the present invention is movably connected to a controller 51 through a connecting rod 50. The controller 51 adopts an industrial-grade touch screen all-in-one machine, adopts capacitive touch technology, and supports multi-touch operation. The connecting rod 50 allows the controller 51 to freely adjust the position and angle in three-dimensional space, which is convenient for the operator to operate and use.
