Description

Technical Field

[0001] This utility model relates to the field of aluminum-coated film technology, and in particular to a novel aluminum-coated film slitting machine. Background Technology

[0002] Metallized film slitting machines are widely used in packaging, printing, electronics, and construction industries. In the packaging industry, metallized film is widely used for packaging food, pharmaceuticals, and cosmetics due to its moisture-proof and oxidation-resistant properties. In the electronics industry, metallized film is used as a raw material for electronic components such as capacitors and batteries due to its excellent conductivity. Furthermore, in the construction sector, metallized film is also used for surface protection of building materials to improve their weather resistance and corrosion resistance.

[0003] For example, the aluminum-coated film slitting machine disclosed in Chinese Patent No. CN223028596U works on the following principle: "It includes a blade holder, and a slitting blade is connected to the outer peripheral wall of the blade holder via a sliding member. The slitting blade is hollow, and two connecting blocks are connected to the inner peripheral wall of the slitting blade. The ends of the connecting blocks are constricted, and a return spring is fixedly connected to the inner end of each connecting block." This utility model relates to the technical field of aluminum-coated film slitting. In use, this aluminum-coated film slitting machine allows the slitting blade to be moved via the sliding member, and the connecting member enables the slitting blade to... The blade holder is connected to the slitting blade, allowing the water pump to deliver coolant into the blade. This ensures the slitting blade operates at a constant temperature, thus allowing for adjustment of the distance between the blades while preventing friction from causing the blades to overheat and accelerate the volatilization of organic components in the aluminum-coated film, which could harm the surrounding environment and workers. While a fixed connecting piece delivers coolant to the slitting blade, the rigid connection between the blade and the blade holder limits the blade's movement to a fixed distance, failing to meet the fine-tuning requirements of high-precision slitting operations. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution: A novel aluminum-coated film slitting machine includes a rotating shaft, a slitting wheel movably disposed around the rotating shaft, two symmetrically distributed placement grooves on the rotating shaft, several fixing grooves on the outer wall of the rotating shaft, a liquid storage tank on the inner wall of the rotating shaft, and a water circulation assembly for cooling the slitting wheel disposed inside the liquid storage tank; a fixing block is slidably disposed inside the fixing groove, and a limiting component for fixing the slitting wheel inside the rotating shaft is disposed inside the fixing block.

[0005] As an improvement to the above technical solution, the water circulation component includes a water pump, a connecting pipe, and a telescopic threaded pipe. The water pump is provided at both ends of the liquid storage tank. The water pump is connected to the telescopic threaded pipe provided in the placement tank through the connecting pipe. The cutting wheel is provided with a circulation groove, and the circulation groove is connected to the connecting pipe. One end of the telescopic threaded pipe is connected to the connecting pipe on the cutting wheel.

[0006] As an improvement to the above technical solution, the limiting component includes a bidirectional threaded shaft, a movable plate, and a nut. The bidirectional threaded shaft is rotatably disposed inside the fixed block. The inner ring of the cutting wheel has an annular groove. The movable plate is movably sleeved on both ends of the bidirectional threaded shaft inside the fixed block through a bidirectional thread. The movable plate is movably disposed inside the annular groove. One end of the bidirectional threaded shaft passes through the fixed block, and the end that passes through is threaded. The end that passes through the bidirectional threaded shaft is provided with a nut through the thread.

[0007] As an improvement to the above technical solution, friction strips are provided on the contact surface between the moving plate and the annular groove.

[0008] As an improvement to the above technical solution, a hexagonal groove for rotation is provided at one end of the bidirectional threaded shaft.

[0009] The beneficial effects of this utility model are as follows: the cooling of the slitting wheel is achieved through the liquid storage tank and water circulation component inside the rotating shaft. The coolant achieves closed-loop flow through the water circulation component, effectively absorbing the high temperature generated during the slitting process and preventing the aluminum-coated film from reacting chemically with the slitting blade due to excessive temperature. This prevents damage to the surface of the aluminum-coated film and the generation of toxic gases. At the same time, the limiting component allows the slitting wheel to adjust its axial position on the rotating shaft, ensuring that the cutting speed can be adjusted when the slitting wheel is cutting the aluminum-coated film, thereby improving the slitting accuracy and product quality stability.

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0015] Please see Figure 1-3 This utility model provides a technical solution: a novel aluminum-coated film slitting machine, including a rotating shaft 10, a slitting wheel 11 movably arranged around the rotating shaft 10, two symmetrically distributed placement grooves 12 on the rotating shaft 10, a plurality of fixing grooves 13 opened on the outer wall of the rotating shaft 10, a liquid storage tank 14 arranged on the inner wall of the rotating shaft 10, and a water circulation component for cooling the slitting wheel 11 arranged inside the liquid storage tank 14; a fixing block 23 is slidably arranged inside the fixing groove 13, and a limiting component for fixing the slitting wheel 11 inside the rotating shaft 10 is arranged inside the fixing block 23.

[0016] In this embodiment, the cooling of the slitting wheel 11 is achieved through the liquid storage tank 14 inside the rotating shaft 10 and the water circulation component. The coolant achieves closed-loop flow through the water circulation component, effectively absorbing the high temperature generated during the slitting process, avoiding chemical reaction between the aluminum-coated film and the slitting blade due to excessive temperature, thereby preventing damage to the surface of the aluminum-coated film and the generation of toxic gases. At the same time, the limiting component allows the slitting wheel 11 to adjust its axial position on the rotating shaft 10, ensuring that the cutting speed of the slitting wheel 11 can be adjusted when cutting the aluminum-coated film, thus improving the slitting accuracy and product quality stability.

[0017] Specifically, the water circulation component includes a water pump 20, a connecting pipe 21, and a telescopic threaded pipe 22. The water pump 20 is installed at both ends of the liquid storage tank 14. The water pump 20 is connected to the telescopic threaded pipe 22 installed in the placement tank 12 through the connecting pipe 21. The cutting wheel 11 has a circulation groove inside, and the circulation groove is connected to the connecting pipe 21. One end of the telescopic threaded pipe 22 is connected to the connecting pipe 21 on the cutting wheel 11.

[0018] In this embodiment, the water circulation component uses a telescopic threaded pipe 22 that is directly connected to the circulation groove 25 of the slitting wheel 11. The telescopic threaded pipe 22 can freely extend and retract with the axial movement of the slitting wheel 11, avoiding the problem of coolant leakage or poor flow caused by the adjustment of the position of the slitting wheel 11 in traditional fixed pipes. The closed-loop design of the water pump 20 and the connecting pipe 21 ensures efficient circulation of coolant, makes the temperature of the slitting wheel 11 uniformly distributed, extends the service life of the slitting wheel 11, and reduces the defect rate of aluminum coating film caused by local overheating.

[0019] The telescopic threaded tube 22 is movably set inside the placement groove 12 by a ring to prevent the telescopic threaded tube 22 from twisting and deforming due to centrifugal force, which would affect the stability of coolant flow.

[0020] Specifically, the limiting components include a bidirectional threaded shaft 24, a movable plate 26, and a nut 27. The bidirectional threaded shaft 24 is rotatably mounted inside the fixed block 23. The inner ring of the cutting wheel 11 has an annular groove 25. The movable plate 26 is movably mounted on both ends of the bidirectional threaded shaft 24 inside the fixed block 23 via bidirectional threads. The movable plate 26 is movably mounted inside the annular groove 25. One end of the bidirectional threaded shaft 24 passes through the fixed block 23, and the end that passes through is threaded. The end that passes through the bidirectional threaded shaft 24 is provided with a nut 27 via threads.

[0021] In this embodiment, the limiting component achieves quick fixing and release of the slitting wheel 11 through the bidirectional threaded shaft 24 and the moving plate 26. When the bidirectional threaded shaft 24 is rotated, the moving plates 26 at both ends move synchronously towards or away from each other, engaging or disengaging from the annular groove 25 of the inner ring of the slitting wheel 11. The operation is simple and the fixing force is uniform. The slitting wheel 11 can be disassembled and assembled without complicated tools, which significantly improves the equipment maintenance efficiency and the flexibility of replacing the slitting wheel 11.

[0022] Specifically, friction strips are provided on the contact surface between the movable plate 26 and the annular groove 25.

[0023] In this embodiment, the friction strips provided on the contact surface between the moving plate 26 and the annular groove 25 effectively prevent the slitting wheel 11 from sliding axially when rotating at high speed or under force by increasing the friction coefficient of the contact surface. The elastic material of the friction strips can adapt to the small dimensional deviations of the annular groove 25, ensuring the reliability of the fixation and avoiding problems such as the slitting wheel 11 shifting or the edge of the aluminum-coated film being damaged due to unstable fixation, thereby improving the stability of the slitting process and the finished product qualification rate.

[0024] Specifically, one end of the bidirectional threaded shaft 24 has a hexagonal groove for rotation.

[0025] In this embodiment, the hexagonal groove at one end of the bidirectional threaded shaft 24 can be adapted to a standard hex wrench, enabling rapid rotation of the bidirectional threaded shaft 24. Compared with the traditional thread adjustment method, this simplifies the fixing process of the slitting wheel 11, allowing operators to complete the disassembly, assembly, and position adjustment of the slitting wheel 11 with one hand, reducing labor intensity and improving the ease of use of the equipment.

[0026] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
