A die-cutting machine for labels and stickers and its usage method

Abstract

This invention relates to a die-cutting machine for labels and a method of using the same. The machine includes a main body and an operating table connected to the main body. A die base mechanism is mounted on the main body, comprising a lower die base and an upper die base. The lower die base is fixedly mounted on the main body, and a lifting guide rod is slidably mounted on it. The method involves fixing suction nozzles to both sides of the base. After die-cutting, when the lifting guide rod reaches its highest position, the air guide groove connects to the suction nozzle. The negative pressure provided by the suction nozzle instantly removes dust, preventing it from adhering to the die cutter and causing blade wear, thus ensuring die-cutting quality. A sleeve is connected to the suction nozzle. During suction, negative pressure is generated inside the sleeve, pushing the piston plate and causing the piston rod to rise, lifting the die-cut product and preventing electrostatic adsorption. When the lifting guide rod descends, the air guide groove connects to the adsorption groove, and the negative pressure connects to the suction hole, adsorbing and fixing the label to prevent displacement.

Description

Technical Field

[0001] This invention belongs to the field of die-cutting machine technology, specifically relating to a die-cutting machine for labels and stickers and its usage method. Background Technology

[0002] Label and sticker die-cutting machines are core equipment designed for the precise forming and processing of flexible materials such as labels and stickers. They are widely used in industries such as packaging and printing. Their core working principle is to use preset steel blades and hardware molds, in conjunction with an automated feeding mechanism, to complete the integrated processing of self-adhesive, coated paper, PET, PVC and other substrates according to the design pattern, including creasing, cutting and waste removal, and finally obtain label products with regular shapes and smooth edges.

[0003] In existing equipment, raw materials often cannot be fixed during the die-cutting process, which can easily lead to material displacement and affect die-cutting accuracy. The dust generated during die-cutting is mostly cleaned manually. If the cleaning is not timely or thorough, residual dust can easily wear down the die blade, increasing maintenance costs and reducing efficiency. During the movement of raw materials, static electricity can easily attract them to the template. In this case, excessive pulling of the feeding mechanism can easily damage the raw materials. Summary of the Invention

[0004] The purpose of this invention is to provide a die-cutting machine for label stickers that uses negative pressure to adsorb dust and fix raw materials, and a method for using the same, in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] A die-cutting machine for labels includes a die-cutting machine body and an operating table connected to the die-cutting machine body. A die base mechanism is provided on the die-cutting machine body. The die base mechanism includes a lower die base and an upper die base. The lower die base is fixedly mounted on the die-cutting machine body. A lifting guide rod is slidably mounted on the lower die base. The upper die base is fixedly mounted on the lifting guide rod. An air guide groove is provided on the lifting guide rod. An adjustment connector is provided on the die base mechanism.

[0007] It also includes:

[0008] The suction connector is mounted on the lower mold base and is connected to the air guide groove and the regulating connector.

[0009] An adsorption air groove is provided on the lower mold base. When the lifting guide rod leaves the highest point, the adsorption air groove is connected to the air guide groove.

[0010] A dust collection mechanism is mounted on a lower mold base. The dust collection mechanism includes a dust collection nozzle. When the lifting guide rod rises to its highest position, the dust collection nozzle is connected to the air guide groove.

[0011] A top support mechanism is provided on the lower mold base. The top support mechanism includes a sleeve that is connected to a dust suction nozzle.

[0012] As a further optimization of the present invention, the mold base mechanism further includes a movable base and a reciprocating assembly. The reciprocating assembly includes a bearing seat, which is fixedly mounted on the body of the die-cutting machine. An eccentric wheel is rotatably mounted on the bearing seat, and a connecting rod is rotatably mounted on the eccentric wheel. The connecting rod is rotatably connected to the movable base. The lifting guide rod is fixedly mounted through the four corners of the movable base, and the movable base is slidably mounted on the lower mold base via the lifting guide rod.

[0013] As a further optimization of the present invention, the lower mold base includes a base body, the lifting guide rod is slidably disposed at the four corners of the base body, a base plate is fixedly disposed on the base body, a lower template is disposed on the base plate, and a plurality of air suction holes are opened on the lower template.

[0014] As a further optimization of the present invention, a wear-resistant sleeve is fitted on the lifting guide rod, the wear-resistant sleeve is fixedly mounted on the base body, and multiple air ports are opened on the wear-resistant sleeve. Spring pads are fixedly mounted on both sides of the bearing seat, and the lifting guide rod is slidably mounted through the spring pads. A spring is fitted on the lifting guide rod, and the two ends of the spring are respectively connected to the spring pads and the movable seat.

[0015] As a further optimization of the present invention, the air guide groove includes a vertical groove A, which is always connected to the air intake connector. A horizontal groove is connected to the vertical groove A, and the other end of the horizontal groove is connected to a vertical groove B. The horizontal groove is movably connected to the adsorption air groove and the dust suction nozzle.

[0016] As a further optimization of the present invention, the suction nozzle is fixedly installed on both sides of the base, with a gap between the suction nozzle and the base. A three-way connector is connected to both ends of the suction nozzle, and a connecting pipe A and a connecting pipe B are respectively connected to both ends of the three-way connector. The connecting pipe A is connected to one of the connecting air ports.

[0017] As a further optimization of the present invention, the adsorption gas groove is formed on the base plate, the adsorption gas groove has an L-shaped structure, the adsorption gas groove is connected to an adsorption gas pipe, the adsorption gas pipe is connected to another connecting gas port, and the adsorption gas groove is connected to the suction hole.

[0018] As a further optimization of the present invention, the sleeve is fixedly mounted on the base, a piston rod is slidably mounted through the sleeve, a piston plate is fixedly mounted at the lower end of the piston rod, a spring is connected between the piston plate and the sleeve, a top support air pipe is connected to the sleeve, and the top support air pipe is connected to the connecting pipe B.

[0019] A method for using a die-cutting machine for labels / stickers is as follows:

[0020] S1: The label sticker material is conveyed on the main body of the die-cutting machine via the transport roller, and the position of the material is adjusted so that it passes under the dust suction nozzle;

[0021] S2: Turn on the power of the die-cutting machine and start the equipment operation switch. The eccentric wheel on the bearing seat rotates, which drives the connecting rod to pull the moving seat. The moving seat slides on the lower die seat through the lifting guide rod, thereby driving the upper die seat to move closer to the lower die seat.

[0022] S3: Adjust the air pressure by adjusting the connector. The suction connector is continuously connected to the lifting guide rod. When the lifting guide rod descends away from the highest point, the air guide groove is connected to the suction hole through the adsorption air groove, thereby adsorbing and fixing the label sticker on the lower template. The upper mold base descends with the moving seat to die-cut the label sticker.

[0023] S4: After die-cutting is completed, the lifting guide rod rises to the highest position, and the horizontal groove is connected to the dust suction nozzle through the connecting pipe A. The dust suction nozzle sucks in the dust generated during die-cutting and treats it. At the same time, a negative pressure is generated in the sleeve connected to the dust suction nozzle, which causes the piston rod to rise and lift the die-cut label sticker.

[0024] S5: After the operation is completed, turn off the power to the equipment and disconnect the air circuit.

[0025] The beneficial effects of this invention are as follows:

[0026] 1. Unlike existing technologies, in actual use, by fixing the dust suction nozzle to both sides of the base, after die-cutting, when the lifting guide rod is raised to the highest position, the air guide groove is connected to the dust suction nozzle through the connecting pipe A and the three-way connector. The negative pressure provided by the air suction connector can immediately suck away the dust, preventing it from adhering to the die-cutting blade and causing wear and breakage of the cutting edge, thus extending the die-cutting blade life and ensuring the die-cutting quality.

[0027] 2. Unlike existing technologies, in actual use, the sleeve is connected to the suction nozzle through the top support air pipe and connecting pipe B. When vacuuming, a negative pressure is generated inside the sleeve, which pushes the piston plate and drives the piston rod to rise, lifting the die-cut product and avoiding electrostatic adsorption.

[0028] 3. Unlike existing technologies, in actual use, the adsorption air groove is connected to the connecting air port of the wear-resistant sleeve and the air suction hole of the lower template through the adsorption air pipe. When the lifting guide rod descends, the air guide groove is connected to the adsorption air groove, and the negative pressure is connected to the air suction hole to adsorb and fix the label sticker in all directions and avoid displacement.

[0039] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0040] Example 1, such as Figure 1 - Figure 9As shown, a die-cutting machine for labels includes a die-cutting machine body 1, an operating table 11 connected to the die-cutting machine body 1, and a feeding mechanism. A control module is installed in the operating table 11 and is electrically connected to the feeding mechanism. A die base mechanism 2 is installed on the die-cutting machine body 1. The die base mechanism 2 includes a lower die base 21 and an upper die base 22. The lower die base 21 is fixedly installed on the die-cutting machine body 1, and a lifting guide rod 3 is slidably installed on the lower die base 21. The upper die base 22 is fixedly installed on the lifting guide rod 3. A die-cutting cutter is installed at the bottom of the upper die base 22. An air guide groove 31 is provided on the lifting guide rod 3. An adjustment connector 8 is provided on the die base mechanism 2, and an air suction connector 7 is provided on the lower die base 21. The air suction connector 7 is connected to... The air guide groove 31 and the regulating connector 8 are connected. The regulating connector 8 is connected to an external air source. An adsorption air groove 6 is provided on the lower mold base 21. When the lifting guide rod 3 is away from the highest position, the adsorption air groove 6 is connected to the air guide groove 31. A dust collection mechanism 5 is provided on the lower mold base 21. The dust collection mechanism 5 includes a dust collection nozzle 51. When the lifting guide rod 3 rises to the highest position, the dust collection nozzle 51 is connected to the air guide groove 31. A top support mechanism 4 is provided on the lower mold base 21. The top support mechanism 4 includes a sleeve 41. The sleeve 41 is connected to the dust collection nozzle 51. The die-cutting machine body 1 provides the installation foundation for the entire equipment and ensures the stable operation of each component. The operating table 11 is convenient for operators. Its internal control module can accurately control the feeding mechanism to ensure feeding. The material speed is matched with the die-cutting rhythm; the lower die base 21 is fixed to ensure stability during die-cutting, and the upper die base 22 slides with the lifting guide rod 3 to realize the up and down die-cutting action; the air guide groove 31 on the lifting guide rod 3 is the key channel for air circulation, which can realize the switching between adsorption and dust collection functions; the regulating connector 8 can adjust the air pressure to meet the adsorption and dust collection needs under different die-cutting scenarios; the suction connector 7 provides a stable air source input for the air path; the adsorption air groove 6 is always connected to the air guide groove 31 when the lifting guide rod 3 leaves the highest point and during the descent, providing an air path for the adsorption and fixation of labels and stickers; the dust suction nozzle 51 is connected to the air guide groove 31 when the lifting guide rod 3 rises to the highest point, which can clean up die-cutting waste in time; the sleeve 41 and The suction nozzle 51 is connected and can drive the top support mechanism 4 to move using the negative pressure of the air path. In the subsequent die-cutting process, the control module will first control the feeding mechanism to transport the label sticker material to the designated position. Then, when the lifting guide rod 3 descends away from the highest position, the air source input by the suction connector 7 will be adsorbed onto the lower mold base 21 through the air guide groove 31 and the adsorption air groove 6 to prepare for die-cutting. After die-cutting is completed, the lifting guide rod 3 rises to the highest position, and the air source enters the suction nozzle 51 through the air guide groove 31 to clean up the waste. At the same time, negative pressure is generated in the sleeve 41, which drives the top support mechanism 4 to lift the die-cut label sticker. The regulating connector 8 adjusts the air path pressure throughout the process to ensure that the adsorption, suction and top support actions are stable and reliable.

[0041] like Figure 2 - Figure 5As shown, the die base mechanism 2 also includes a movable seat 23 and a reciprocating assembly 24. The reciprocating assembly 24 includes a bearing seat 241, which is fixedly mounted on the die-cutting machine body 1. An eccentric wheel 242 is rotatably mounted on the bearing seat 241 and is connected to a servo motor, which is electrically connected to a control module. A connecting rod 243 is rotatably mounted on the eccentric wheel 242 and is rotatably connected to the movable seat 23. A lifting guide rod 3 is fixedly mounted through the four corners of the movable seat 23. The movable seat 23 is slidably mounted on the lower die base 21 via the lifting guide rod 3. The lower die base 21 includes a seat body 211, and the lifting guide rod 3 is slidably mounted at the four corners of the seat body 211. A base plate 212 is fixedly installed on the upper part of the mold base 212, and a lower template 213 is installed on the base plate 212. Multiple suction holes 214 are opened on the lower template 213. An adsorption groove 6 is opened on the base plate 212 and has an L-shaped structure. An adsorption pipe 61 is connected to the adsorption groove 6. The suction holes 214 correspond to and communicate with the upper openings of the adsorption groove 6. The movable seat 23 serves as the mounting carrier for the lifting guide rod 3, enabling it to drive the lifting guide rod 3 and the upper mold base 22 to move synchronously. Lifting guide rods 3 are installed at the four corners to ensure smooth movement of the movable seat 23 and prevent the upper mold base 22 from tilting. The reciprocating assembly 24 is the core component driving the reciprocating motion of the movable seat 23. The bearing seat 241 provides stable support for the eccentric wheel 242, preventing it from tilting. The eccentric wheel 242, in conjunction with the servo motor, converts the motor's rotational motion into the reciprocating motion of the connecting rod 243. The servo motor, controlled by the control module, can precisely adjust the speed and stroke to meet different die-cutting requirements. The connecting rod 243 transmits power between the eccentric wheel 242 and the moving seat 23. The seat 211 provides sliding support for the lifting guide rod 3, ensuring stable movement of the lifting guide rod 3. The base plate 212 provides installation space for the adsorption air groove 6. The L-shaped structure of the adsorption air groove 6 optimizes the air path layout, ensuring uniform transmission of adsorption force. The lower template 213 is the bearing surface for label die-cutting. Multiple suction holes 214 ensure that the adsorption force is evenly applied to the label, avoiding localized uneven application. Adsorption causes die-cutting displacement; the adsorption air groove 6 connects the adsorption air pipe 61 and the suction hole 214, providing a channel for the air path. After the equipment is started, the control module controls the servo motor to run, which drives the eccentric wheel 242 on the bearing seat 241 to rotate. The eccentric wheel 242 pulls the moving seat 23 through the connecting rod 243. The moving seat 23 slides on the seat body 211 with the help of the lifting guide rods 3 at the four corners, thereby driving the upper die seat 22 to move closer to or away from the lower die seat 21. During die-cutting, the negative pressure in the adsorption air groove 6 is transmitted to the suction hole 214 of the lower template 213 through the adsorption air pipe 61, firmly adsorbing the label sticker onto the lower template 213, ensuring that the raw material position is stable when the upper die seat 22 presses down for die-cutting, and improving the die-cutting accuracy.

[0042] like Figure 4 - Figure 5 and Figure 7As shown, a wear-resistant sleeve 33 is fitted onto the lifting guide rod 3, and the wear-resistant sleeve 33 is fixedly mounted on the base 211. Multiple air ports 331 are opened on the wear-resistant sleeve 33. Spring pads 32 are fixedly mounted on both sides of the bearing seat 241. The lifting guide rod 3 is slidably mounted on the spring pads 32. A spring 321 is fitted onto the lifting guide rod 3, and both ends of the spring 321 are connected to the spring pads 32 and the movable seat 23, respectively. The air guide groove 31 includes a vertical groove A311, which is always connected to the suction connector 7. A horizontal groove 312 is connected to the vertical groove A311, and the other end of the horizontal groove 312 is connected to a vertical groove B313. The horizontal groove 312 is movably connected to the adsorption air groove 6 and the dust suction nozzle 51. The wear-resistant sleeve 33 can reduce the friction between the lifting guide rod 3 and the base. The direct friction of 211 reduces component wear and extends the service life of the lifting guide rod 3 and the base 211. The fixed setting of the wear-resistant sleeve 33 ensures its stable position and does not affect the sliding of the lifting guide rod 3. Multiple connecting air ports 331 can be connected to different air circuit components respectively. The spring pad 32 provides fixed support for the spring 321, ensuring the stable installation of the spring 321. The vertical groove A311 of the air guide groove 31 is always connected to the suction connector 7 to ensure a continuous supply of air. The horizontal groove 312 can be connected to the adsorption air groove 6 and the dust suction nozzle 51 respectively according to the position change of the lifting guide rod 3, realizing the automatic switching of adsorption and dust suction functions. The vertical groove B313 is always connected to the adsorption air pipe 61 during the descent of the lifting guide rod 3 to assist the air circuit and ensure the air circuit is unobstructed.

[0043] like Figure 4 and Figure 8 As shown, the suction nozzles 51 in the suction mechanism 5 are fixedly installed on both sides of the base 211, with a gap between the suction nozzles 51 and the base 211. A three-way connector 511 is connected to both ends of the suction nozzles 51, with connecting pipes A52 and B53 connected to each end. Connecting pipe A52 is connected to one of the connecting air ports 331, and the adsorption air pipe 61 is connected to the other connecting air port 331. The adsorption air pipe 61 is connected to the suction hole 214 through the adsorption air groove 6. The suction nozzles 51 are fixed on both sides of the base 211, fully covering both sides of the die-cutting area, thus allowing for cleaning of the raw material surface before and after die-cutting. The gap between the suction nozzles 51 and the base 211 facilitates... Label sticker material conveying; the three-way connector 511 can simultaneously connect the suction nozzle 51 to the connecting pipe A52 and the connecting pipe B53, so that the air path can provide negative pressure for suction and top support at the same time, simplifying the air path structure; the connecting pipe A52 connects the suction nozzle 51 to the air guide groove 31, ensuring that the air source can smoothly enter the suction nozzle 51; the connecting pipe B53 connects the suction nozzle 51 to the top support mechanism 4, so that the suction and top support actions can be carried out synchronously; the adsorption air pipe 61 connects to the air guide groove 31 through the connecting air port 331 and connects to the suction hole 214, providing an air path channel for label sticker adsorption, and uses different connecting air ports 331 from the connecting pipe A52 to avoid air path interference.

[0044] like Figure 8 - Figure 9 As shown, sleeve 41 is fixedly mounted on base 211. A piston rod 42 is slidably mounted through sleeve 41. A piston plate 421 is fixedly mounted at the lower end of piston rod 42. A spring 43 connects piston plate 421 and sleeve 41. A top support air pipe 411 is connected to sleeve 41 and is connected to connecting pipe B53. Sleeve 41 is fixed on base 211, providing installation and movement space for piston rod 42 and piston plate 421, ensuring the overall stability of top support mechanism 4. Piston rod 42 can slide inside sleeve 41, and its highest point can directly contact the die-cut label. The sticker contacts the sleeve to initiate the lifting action; the piston plate 421 engages with the inner wall of the sleeve 41 to form a sealed space. When negative pressure is generated inside the sleeve 41, it can drive the piston plate 421 to move upward, and the piston rod 42 fixed on the piston plate 421 moves synchronously; the second spring 43 has a reset function. After the negative pressure inside the sleeve 41 disappears, it can push the piston plate 421 and the piston rod 42 to reset, preparing for the next lifting action; the lifting air pipe 411 connects the sleeve 41 with the connecting pipe B53, so that the negative pressure at the suction nozzle 51 can be transmitted to the sleeve 41 to drive the lifting mechanism 4 to move.

[0045] It should be noted that the die-cutting machine for this label sticker operates as follows:

[0046] S1: The label sticker material is conveyed on the die-cutting machine body 1 by the conveyor roller. The position of the material is adjusted so that it passes under the dust suction nozzle 51. The specific process is as follows: Before the equipment is started, the label sticker material is conveyed to the operating table 11 of the die-cutting machine body 1 by the conveyor roller and the position of the material is adjusted to ensure that it passes precisely under the dust suction nozzle 51 and directly above the lower template 213.

[0047] S2: Turn on the power to the die-cutting machine and start the equipment operation switch. The eccentric wheel 242 on the bearing seat 241 rotates, driving the connecting rod 243 to pull the moving seat 23. The moving seat 23 slides on the lower die seat 21 through the lifting guide rod 3, thereby driving the upper die seat 22 to move closer to the lower die seat 21. The specific process is as follows: After turning on the power and starting the operation switch, the servo motor drives the eccentric wheel 242 on the bearing seat 241 to start rotating. Since the center of the eccentric wheel 242 is not concentric with the rotating shaft, during its rotation, it will pull the moving seat 23 to move up and down reciprocally through the rotating connecting rod 243. At this time, the lifting guide rods 3 fixed at the four corners of the moving seat 23 will slide in the wear-resistant sleeves 33 at the four corners of the seat body 211. The wear-resistant sleeves 33 can reduce the direct friction between the lifting guide rods 3 and the seat body 211 and extend the service life of the components. Meanwhile, the spring 321 fitted on the lifting guide rod 3 will be compressed or extended under the drive of the moving seat 23, using elasticity to provide buffer for the reciprocating motion of the moving seat 23 and ensure the smoothness of the motion.

[0048] S3: The air pressure is adjusted by adjusting connector 8, and the suction connector 7 is continuously connected to the lifting guide rod 3. When the lifting guide rod 3 descends away from the highest position, the air guide groove 31 is connected to the suction hole 214 through the adsorption air groove 6, thereby adsorbing and fixing the label sticker onto the lower template 213. The upper mold base 22 descends with the moving base 23 to die-cut the label sticker. The specific process is as follows: First, the overall air pressure is adjusted by adjusting connector 8, and the suction connector 7 is continuously connected to the vertical groove A311 inside the lifting guide rod 3 to provide a stable air source for adsorption and subsequent dust collection. When the lifting guide rod 3 descends away from the highest position, its internal vertical groove B313 will be connected to the adsorption air pipe 61. The adsorption air groove 6 is an L-shaped structure opened on the base plate 212. It is connected to one of the connecting air ports 331 on the wear-resistant sleeve 33 through the adsorption air pipe 61, thereby forming an air passage with the vertical groove B313. Since the adsorption air pipe 61 is also connected to the suction hole 214 on the lower template 213 through the adsorption air groove 6, the negative pressure generated by the air source will be transmitted sequentially through the vertical groove A311, the horizontal groove 312, the vertical groove B313, the adsorption air pipe 61, and the adsorption air groove 6 to the suction hole 214, firmly adsorbing and fixing the label sticker above the lower template 213, preventing the material from shifting during the die-cutting process and causing a decrease in die-cutting accuracy. During this process, as the lifting guide rod 3 continues to move downward, the vertical groove B313 will always remain connected to the adsorption air pipe 61 to ensure the continuous stability of the adsorption force. After the label sticker is fixed on the lower template 213 by the adsorption force of the suction hole 214, the moving seat 23 continues to drive the lifting guide rod 3 to move downward, thereby pushing the upper mold base 22 fixed at the highest point of the lifting guide rod 3 to continuously approach the lower mold base 21. When the lower template 213 on the lower mold base 21 contacts the die-cutting tool on the upper mold base 22, the pressure of the upper mold base 22 is used to complete the die-cutting process of the label sticker. Because the movement of the moving seat 23 is precisely controlled by the eccentric wheel 242 and the connecting rod 243 throughout the process, and the label sticker is stably adsorbed, the accuracy of the die-cutting size and the flatness of the cut can be effectively guaranteed.

[0049] S4: After die-cutting, the lifting guide rod 3 rises to its highest position, and the transverse groove 312 is connected to the dust suction nozzle 51 through the connecting pipe A52. The dust suction nozzle 51 sucks in the dust generated during die-cutting. At the same time, a negative pressure is generated in the sleeve 41 connected to the dust suction nozzle 51, causing the piston rod 42 to rise and lift the die-cut label sticker. The specific process is as follows: After die-cutting, the eccentric wheel 242 continues to rotate, and the moving seat 23 and the lifting guide rod 3 are pulled upward to reset through the connecting rod 243. The raw material is transported again. When the lifting guide rod 3 rises to its highest position, the connection between the transverse groove 312 inside it and the adsorption air groove 6 is disconnected, and it is connected to the dust suction nozzle 51 to form an air passage. The suction nozzle 51 is fixed on both sides of the base 211, with a gap between it and the base 211 for the raw materials to pass through. Its two ends are connected to the connecting pipe A52 and the connecting pipe B53 respectively through the three-way connector 511. The connecting pipe A52 is connected to another connecting air port 331 on the wear-resistant sleeve 33, thereby realizing the connection with the transverse groove 312. At this time, the negative pressure provided by the suction connector 7 is transmitted to the suction nozzle 51 through the vertical groove A311, the horizontal groove 312, the connecting pipe A52, and the three-way connector 511, sucking the waste material generated during die-cutting into the suction nozzle 51, completing the immediate cleaning of waste material and preventing waste material accumulation from affecting subsequent processing. At the same time, the connecting pipe B53 connected to the three-way connector 511 transmits the negative pressure to the sleeve 41 of the top support mechanism 4. Under the action of negative pressure, the piston plate 421 in the sleeve 41 moves upward, driving the piston rod 42 to extend upward out of the sleeve 41, lifting the die-cut label sticker on the lower template 213, facilitating continuous transportation and preventing the raw material from adhering to the lower template 213 due to static electricity. When the lifting guide rod 3 descends again, since the sleeve 41 is connected to the suction nozzle 51, the negative pressure in the sleeve 41 quickly disappears, and the piston plate 421 will reset under the elastic force of the spring 43, driving the piston rod 42 to retract into the sleeve 41, preparing for the next die-cutting cycle.

[0050] S5: After the operation is completed, turn off the power to the equipment and disconnect the air circuit connection. The specific process is as follows: After a batch of label die-cutting operations is completed, turn off the power to the equipment, disconnect the connection between the control connector 8 and the external air source, and at the same time disconnect the air circuit control of the control connector 8 to the suction connector 7 to complete the shutdown and reset of the equipment.
