Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, and in particular to a composite punching mold for multi-material hot melt adhesive tape. Background Technology

[0002] Hot melt adhesive tape, as an adhesive made of thermoplastic polymers, is solid at room temperature and is easy to store and transport. As the application scenarios demand higher material performance, multi-material hot melt adhesive tape has been developed. It is composed of multiple functional materials and can meet more complex usage needs. Composite die-cutting molds for multi-material hot melt adhesive tape are important tools in production.

[0003] The composite die for multi-material hot melt adhesive tape is a precision tooling device that integrates composite and die-cutting functions. It uses heating or pressurizing devices to precisely composite hot melt adhesive materials with different properties with the substrate. At the same time, it uses high-precision die cutting edges and die-cutting mechanisms to accurately cut the required specifications according to the preset shape. This ensures both a strong composite between multiple materials and small dimensional errors in the cut tape.

[0004] Although composite die-cutting molds for multi-material hot melt adhesive tapes can quickly cut the tapes, the waste generated from multi-material cutting contains fragments of different materials. Traditional waste troughs or ejection devices are difficult to separate the waste efficiently. The hot melt adhesive waste will adhere to the inner wall of the waste trough, accumulate and block the channel, affecting production continuity. The existing solution is to design a composite waste discharge device that combines magnetic attraction and pneumatics. The magnetic force attracts the metal waste, while the pneumatic device blows away the non-metallic waste, thus separating waste of different materials. It can also increase the waste collection chamber and periodically discharge the waste in the collection chamber. However, for hot melt adhesive waste with strong adhesion, magnetic attraction and pneumatic methods cannot completely remove it. Some waste still adheres to the mold surface or waste channel. Moreover, the capacity of the waste collection chamber is limited. When the production volume is large, frequent shutdowns for cleaning are still required, affecting production efficiency.

[0033] 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.

[0034] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a composite punching die for multi-material hot melt adhesive tape, including a fixed frame 1, a top plate 2, and a punching blade 10. The punching blade 10 punches the adhesive tape. The outer wall of the fixed frame 1 is provided with a waste collection mechanism 3 for collecting waste. The top of the punching blade 10 is provided with an installation mechanism 6 for mounting the punching blade 10 to an installation block 5. The bottom of the top plate 2 is fixedly connected with multiple guide posts 4, which can guide the installation block 5 when it moves up and down. The outer walls of the multiple guide posts 4 are slidably connected to the same installation block 5, which facilitates the installation of the cutting tool. The top of the top plate 2 is provided with a hydraulic mechanism 7, which provides power for the up and down movement of the cutting blade.

[0035] The waste collection mechanism 3 includes a vacuum pump 301, which provides power for waste collection. The front of the vacuum pump 301 is fixedly connected to the rear of the mounting frame 1. A negative pressure adsorption tube 302 is connected to the top of the vacuum pump 301, which guides the suction force. A suction shell 303 is fixedly connected to the rear top of the mounting frame 1, which collects the waste generated by the device. Multiple electromagnetic adsorption plates 304 are fixedly connected to the inner wall of the suction shell 303, which can prevent smaller pieces of waste from escaping. A collection box 305 is fixedly connected to the left rear end of the mounting frame 1, which is used for centralized processing of waste. The left side of the inner wall of the collection box 305 is fixedly connected to... The system includes a filter screen 306, which concentrates waste material in the collection box 305. An air blowing pipe 307 is connected to the left side of the collection box 305. The air blowing pipe 307 filters and reuses the suction force generated by the vacuum pump 301 to blow the cutting platform. A high-pressure nozzle 308 is fixedly connected to the rear end of the air blowing pipe 307. The high-pressure nozzle 308 is used to spray gas after high-pressure treatment. A steering component 309 is provided on the top front side of the mounting bracket 1. The steering component 309 guides the orientation of the high-pressure nozzle 308. A waste treatment component 310 is provided on the inner wall of the collection box 305. The waste treatment component 310 automatically discharges waste material when there is too much waste material in the collection box 305.

[0036] The steering assembly 309 includes two electrically operated telescopic rods 3091, which provide power for changing the orientation of the high-pressure nozzle 308. The bottom of each of the two electrically operated telescopic rods 3091 is fixedly connected to the top of the mounting bracket 1, and the top of each of the two electrically operated telescopic rods 3091 is fixedly connected to a universal joint 3092, which facilitates the change of orientation of the high-pressure nozzle 308.

[0037] The waste processing assembly 310 includes two electric push rods 3101. The front sides of the two electric push rods 3101 are fixedly connected to the front side of the inner wall of the collection box 305. The rear ends of the two electric push rods 3101 are fixedly connected to the same push plate 3102. The electric push rods 3101 drive the push plate 3102, thereby pushing the waste. The rear side of the inner wall of the collection box 305 is rotatably connected to a recycling door 3103. The automatic opening and closing of the recycling door 3103 can prevent the waste from escaping during collection.

[0038] Specifically, after the punching blade 10 completes the punching of the rubber strip, the waste material is drawn into the suction shell 303 through the negative pressure adsorption pipe 302 under the suction drive of the vacuum pump 301. Multiple electromagnetic adsorption plates 304 on the inner wall of the suction shell 303 can adsorb smaller waste materials, preventing them from escaping. Subsequently, the waste material continues to enter the collection box 305, where the filter screen 306 intercepts it, achieving centralized collection. Simultaneously, the suction generated by the vacuum pump 301, after being filtered by the air blowing pipe 307, is ejected by the high-pressure nozzle 308 to sweep and clean the cutting platform and the steering assembly. The two electric telescopic rods 3091 in component 309, together with the universal joint 3092, can flexibly adjust the orientation of the high-pressure nozzle 308 to ensure comprehensive cleaning of waste. When there is too much waste in the collection box 305, the waste treatment component 310 is activated. The two electric push rods 3101 drive the push plate 3102 to move backward, pushing the waste towards the recycling door 3103, which is rotatably connected to the rear side of the inner wall of the collection box 305. The recycling door 3103 automatically opens to discharge the waste and automatically closes after cleaning is completed. This achieves complete cleaning of waste and avoids the accumulation of waste.

[0039] Reference Figure 2 , Figure 5 and Figure 6 The mounting mechanism 6 includes two connecting blocks 601, the bottom of which is fixedly connected to the top of the punching blade 10. The bottom of the mounting block 5 has two connecting grooves 602, and the connecting blocks 601 and the connecting grooves 602 are slidably connected. The front and rear sides of the mounting block 5 are provided with slots 603, and the inner walls of the two slots 603 are slidably connected with fixing blocks 604. The fixing blocks 604 and the slots 603 are slidably connected. The inner walls of the two slots 603 are fixedly connected with springs 605. The springs 605 enable the fixing blocks 604 to automatically return to their original position after being pulled outward, so that the fixing blocks 604 are always slidably connected to the inner walls of the slots 603. The adjacent sides of the two springs 605 are fixedly connected with limit plates 606, which can prevent the fixing blocks 604 from disengaging from the slots 603. The top of the punching blade 10 is provided with a reinforcing component 607, which is used to reinforce the connection between the connecting blocks 601 and the connecting grooves 602.

[0040] The reinforcement component 607 includes two magnetic blocks 6071. The bottom of the two magnetic blocks 6071 is fixedly connected to the top of the two connecting blocks 601. The top of the inner wall of the two connecting grooves 602 is fixedly connected to magnetic blocks 6072. The reinforcement is achieved by the magnetic attraction between the magnetic blocks 6071 and the magnetic blocks 6072.

[0041] Specifically, when installing the punching cutter 10, first align the two connecting blocks 601 with the connecting grooves 602 at the bottom of the mounting block 5, and slowly insert them upwards. At this time, the connecting blocks 601 press against the fixing block 604 in the slot 603, causing the fixing block 604 to slide into the slot 603 against the elastic force of the spring 605. When the connecting blocks 601 are fully inserted into the connecting groove 602, a gap appears in the corresponding position of the fixing block 604. The spring 605 pushes the fixing block 604 to automatically pop out and lock into the corresponding groove of the connecting block 601, achieving initial... While the connecting block 601 is fixed, the magnetic block 6071 on the top of the connecting block 601 is close to the magnetic block 6072 on the top of the inner wall of the connecting groove 602. The magnetic attraction force tightly attracts the connecting block 6071, further strengthening the connection between the punching blade 10 and the mounting block 5, ensuring the stability during punching operations. When disassembling the punching blade 10, simply pull the fixing block 604 outward manually to compress the spring 605, so that the fixing block 604 is disengaged from the groove of the connecting block 601, and the punching blade 10 can be removed from the mounting block 5, making the installation and removal of the punching blade 10 convenient and quick.

[0042] Reference Figure 1 and Figure 2 The hydraulic mechanism 7 includes a hydraulic cylinder 701. The bottom of the hydraulic cylinder 701 is fixedly connected to the top of the top plate 2. A slide rod 702 is slidably connected to the bottom of the hydraulic cylinder 701. The hydraulic cylinder 701 drives the slide rod 702, causing the mounting block 5 and the punching blade 10 to move up and down. A pressurizing assembly 703 is provided on the top of the top plate 2. The pressurizing assembly 703 provides power to the hydraulic cylinder 701. The pressurizing assembly 703 includes an oil tank 7031, which is used to store hydraulic oil. The bottom end of the oil tank 7031 is fixedly connected to the top left side of the top plate 2. A hydraulic pump 7032 is fixedly connected to the top right side of the top plate 2. The hydraulic pump 7032 can draw hydraulic oil and pressurize it. Two monitors 8 are fixedly connected to the top of the mounting bracket 1. The monitors 8 are used to detect the status of the device. A buzzer 9 is fixedly connected to each adjacent side of the two monitors 8. When the device is abnormal, the buzzer 9 will sound an alarm.

[0043] Specifically, when using hydraulic mechanism 7, hydraulic oil is first drawn from oil tank 7031 by hydraulic pump 7032, pressurized and injected into hydraulic cylinder 701. The high-pressure hydraulic oil pushes slide rod 702 downward, causing mounting block 5 and punching blade 10 to move down, completing the punching action. When hydraulic pump 7032 stops pressurizing and switches the oil circuit direction, hydraulic oil in hydraulic cylinder 701 flows back, and slide rod 702 slides upward under the change of hydraulic oil pressure, causing punching blade 10 to reset. During the operation of the device, monitor 8 monitors the status of the device in real time. When an abnormality is detected, buzzer 9 is immediately triggered and an alarm is issued to remind the operator to stop the machine in time for inspection, ensuring the safe operation of the equipment.

[0044] Working principle: The hot melt adhesive tape is cut by the punch cutter 10, generating waste material. Under the suction of the vacuum pump 301, the waste material is quickly introduced into the suction shell 303 through the negative pressure adsorption tube 302. The electromagnetic adsorption plate 304 on the inner wall of the suction shell 303 uses magnetic force to adsorb the tiny waste materials, preventing them from escaping. Subsequently, the waste material enters the collection box 305, where the filter screen 306 intercepts the waste material, completing the centralized collection of waste material. At the same time, the suction force generated by the vacuum pump 301 is filtered through the air blowing pipe 307 and then sprayed by high pressure. The head 308 is reused to blow and cut the platform. In the steering component 309, the electric telescopic rod 3091, together with the universal joint 3092, can flexibly adjust the nozzle angle to ensure that the waste is completely cleaned. When the collection box 305 is full of waste, the waste treatment component 310 is activated, so that the electric push rod 3101 pushes the push plate 3102 to squeeze the waste to the recycling door 3103. The recycling door 3103 opens under force to discharge the waste, and then closes automatically after cleaning, realizing efficient waste treatment throughout the entire process and avoiding waste accumulation and blockage.

[0045] Furthermore, during the installation of the punching blade 10, the sliding engagement between the connecting block 601 and the connecting groove 602 provides guidance. During insertion, the connecting block 601 presses against the fixing block 604, forcing the spring 605 to compress and deform. When the connecting block 601 is fully in place, the spring 605 releases its elastic potential energy, pushing the fixing block 604 into the groove of the connecting block 601, forming a mechanical lock and achieving initial fixation. At the same time, the magnetic attraction blocks 6071 and 6072 generate magnetic attraction, enhancing the stability of the connection and preventing the punching blade 10 from loosening under high-frequency vibration conditions. During disassembly, the fixing block 604 is pulled by external force to compress the spring 605, releasing the mechanical lock of the fixing block 604 on the connecting block 601. Simultaneously, the external force overcomes the magnetic resistance, allowing the punching blade 10 to be quickly separated. The spring 605 and the limiting plate 606 ensure that the fixing block 604 is reset, preparing for the next installation.
