Description

Technical Field

[0001] This invention belongs to the technical field of composite film cutting equipment, and specifically relates to a composite film cold cutting equipment. Background Technology

[0002] In the processing of composite films, the slitting process is one of the key steps, and composite film cold cutting equipment is usually used to precisely slit the film material. However, in actual operation, there is unavoidable friction between the film and the blade. Existing blades generate a lot of friction when slitting the film, which in turn generates high temperatures. As a result, the adhesive coating of the composite film is prone to sticking to the cutter during cold cutting, leading to film stringing or blade contamination. This requires frequent machine shutdowns for cleaning, resulting in low production efficiency.

[0003] Therefore, a composite film cold cutting device is needed. Summary of the Invention

[0004] The purpose of this invention is to provide a composite film cold cutting device that can clean the cutting tools without stopping the machine, thus ensuring production efficiency. The specific technical solution is as follows:

The first cutting unit and the second cutting unit are arranged symmetrically in a vertical mirror image. The first cutting plate is positioned directly below the first cutting unit, and the second cutting plate is positioned directly above the second cutting unit. The cutting position of the first cutting unit is on the second cutting plate. The first cutting unit can work alternately with the second cutting unit. The cutting position of the second cutting unit is on the first cutting plate.

[0019] Compared with existing technologies, the present invention has the following advantages:

[0020] This invention provides a composite film cold-cutting device. A first cutting unit is located above a second cutting unit. The first and second cutting units operate alternately. When the first cutting unit is operating, a first power unit controls a first cutting plate to move away from the first cutting unit, while a second power unit controls a second cutting plate to move directly below the first cutting unit. A conveying device transports the composite film between the first and second cutting units. When the first cutting unit cuts, the cutter lands on the composite film and the second cutting plate, cutting the composite film on the second cutting plate. After the first cutting unit has been operating for a certain period, if the user believes that there is adhesive residue on the cutter of the first cutting unit, the second cutting unit is activated. At this time, the second cutting plate moves away from the first cutting unit, while the first cutting plate moves directly above the second cutting unit. The cutter of the second cutting unit lands on the composite film and the first cutting plate. During this process, the cutter of the first cutting unit stops operating for cooling and cleaning. Because the first and second cutting units cut the composite film at the same position, continuous production can be achieved by switching between them without stopping the machine, thus improving production efficiency.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0028] Next, the working principle of this embodiment will be described in detail to enable those skilled in the art to better understand the present invention:

[0029] refer to Figures 1 to 3 This invention provides a composite film cold cutting device, which includes a first cutting unit 1, a second cutting unit 2, a first cutting plate 3, a second cutting plate 4, a first power unit 301, and a second power unit 401. The first cutting unit 1 and the second cutting unit 2 are respectively arranged in a mirror image symmetrically. The first cutting plate 3 is located directly below the first cutting unit 1, and the second cutting plate 4 is located directly above the second cutting unit 2. The cutting position of the first cutting unit 1 is on the second cutting plate 4. The first cutting unit 1 can work alternately with the second cutting unit 2. The cutting position of the second cutting unit 2 is on the first cutting plate 3. The first cutting plate 3 is connected to the first power unit 301 to control the lateral movement of the first cutting plate 3. The second cutting plate 4 is connected to the second power unit 401 to control the lateral movement of the second cutting plate 4.

[0030] The first cutting unit 1 is located above the second cutting unit 2. The first cutting unit 1 and the second cutting unit 2 work alternately. When the first cutting unit 1 is working, the first power unit 301 controls the first cutting plate 3 to move away from the first cutting unit 1, while the second power unit 401 controls the second cutting plate 4 to move directly below the first cutting unit 1. The conveying device transports the composite film between the first cutting unit 1 and the second cutting unit 2. When the first cutting unit 1 is cutting, the cutter falls on the composite film and the second cutting plate 4. That is, the cutting position of the first cutting unit 1 is on the second cutting plate 4, and the composite film is cut on the second cutting plate 4. After the first cutting unit 1 has been working for a certain period of time, if the user believes that there is adhesive residue on the cutter of the first cutting unit 1, the second cutting unit 2 is started. At this time, the second cutting plate 4 moves away from the second cutting unit 2, while the first cutting plate 3 moves directly above the second cutting unit 2. The cutter of the second cutting unit 2 falls on the composite film and the first cutting plate 3. That is, the cutting position of the second cutting unit 2 is on the first cutting plate 3. During this process, the cutter of the first cutting unit 1 stops working for cooling and cleaning. Since the first cutting unit 1 and the second cutting unit 2 cut the composite film at the same position, they can be switched without stopping during production, achieving continuous production and improving production efficiency.

[0031] In this embodiment, the first cutting unit 1 includes a first cylinder 102 and a first cutter 101; the first cutter 101 is located inside the first cylinder 102, and first grooves 302 are provided on the lower parts of both sides of the first cylinder 102. The two ends of the first cutting plate 3 are disposed in the first grooves 302, and the first power unit 301 is disposed on the side wall of the first cylinder 102. The side of the first cutting plate 3 is connected to the first power unit 301 to control the first cutting plate 3 to move along the first grooves 302; the second cutting unit 2 includes a second cylinder 20. 2. Second cutter 201; The second cutter 201 is located inside the second cylinder 202. The upper part of both sides of the second cylinder 202 is provided with a second sliding groove 402. The two ends of the second cutting plate 4 are provided in the second sliding groove 402. The second power unit 401 is provided on the side wall of the second cylinder 202. The side of the second cutting plate 4 is connected to the second power unit 401 to control the second cutting plate 4 to move along the second sliding groove 402. The first cylinder 102 and the second cylinder 202 are respectively provided with a first cleaning device 5 and a second cleaning device 6.

[0032] The first cutter 101 can be partially located within the first cylinder 102 to save material. A first chute 302, located at the lower part of the first cylinder 102, allows for the opening and closing of the first cutter 101. The first power unit 301, such as an electric push rod or lead screw nut, is a horizontally propelling device used to control the movement of the first cutting plate 3 within the first chute 302. The second power unit 401 operates similarly and will not be described in detail here. When the first cutting unit 1 is working, the first power unit 301 retracts, causing the first cutting plate 3 to move away from the first cutter 101, while the second power unit 401 extends, causing the second cutting plate 4 to move directly below the first cutter 101. The opposite occurs when the second cutting unit 2 is working. When the first cutting unit 1 stops working, the first cleaning device 5 removes the adhesive adhering to the first cutter 101 and assists in cooling the first cutter 101. Alternatively, when the second cutting unit 2 stops working, the second cleaning device 6 removes the adhesive adhering to the second cutter 201.

[0033] Furthermore, since the first cutting unit 1 and the second cutting unit 2 work alternately, the first power unit 301 and the second power unit 401 can be electrically connected so that the first power unit 301 and the second power unit 401 work in opposite directions.

[0034] In one implementation of this embodiment, the first cleaning device 5 includes a first roller 502, a first drive unit 501, and a first connector 503. First through grooves 504 are provided on both side walls of the first cylinder 102. Both ends of the first roller 502 are installed in the first through grooves 504. The first drive unit 501 is disposed at both ends of the first roller 502. The first roller 502 is connected to the first cutting plate 3 via the first connector 503. The second cleaning device 6 includes a second roller 602, a second drive unit 601, and a second connector 603. Second through grooves 604 are provided on both side walls of the second cylinder 202. Both ends of the second roller 602 are installed in the second through grooves 604. The second drive unit 601 is disposed at both ends of the second roller 602. The second roller 602 is connected to the second cutting plate 4 via the second connector 603.

[0035] The first drive unit 501 and the second drive unit 601 control the rotation of the first roller 502 and the second roller 602, respectively. They are connected to the first cutting plate 3 via the first connector 503. When the first cutting plate 3 moves, it drives the first roller 502 to move. While the first cutting plate 3 closes the first cylinder 102, the first roller 502 cleans the first cutter 101. Since the first cutting plate 3 is located directly below the first cutter 101, the removed impurities fall onto the first cutting plate 3, thus ensuring the quality of the composite film. On the other hand, when the second cutter 201 stops working, the second roller 602 cleans the second cutter 201. The impurities fall downwards and will not affect the composite film.

[0036] In addition, the first drive unit 501 can be a motor, externally mounted on the first cylinder 102, and moves synchronously with the first roller 502. The second drive unit 601 has the same configuration.

[0037] In the first cleaning device 5, a first liquid storage tank 7 is provided inside the first cylinder 102, located above the first roller 502. A first switch is provided in the first liquid storage tank 7. The first liquid storage tank 7 contains a solvent that can dissolve adhesives. When the first cutter 101 is working, the first roller 502 is located below the first liquid storage tank 7. The solvent flow is controlled by the first switch, which can be a solenoid valve. The solvent dripping onto the cotton-material first roller 502 can be absorbed. When the first roller 502 wipes away impurities on the surface of the first cutter 101, it can help dissolve stubborn adhesives. In another implementation, the first switch includes a guide hole 701 located at the bottom of the first liquid storage tank 7, with the bottom of the first liquid storage tank 7 abutting against the first roller 502. The guide hole 701 is a micro-hole with a small diameter, which prevents leakage by means of the surface tension of the liquid. When the cotton first roller 502 comes into contact with the guide hole 701, the surface tension of the liquid is broken and the solvent flows into the first roller 502. At the same time, the solvent can also be drawn out from the first liquid storage tank 7 by the capillary action of the first roller 502.

[0038] In the second cleaning device 6, a second liquid storage tank 8 is provided inside the second cylinder 202, located below the second roller 602. Taking full advantage of the structural layout of the second cutting unit 2, when the second cutter 201 is working, the second roller 602 is positioned above the liquid storage tank. At this time, solvent can be directly added to the second liquid storage tank 8 to allow solvent to adhere to the second roller 602. Furthermore, a water level regulator 801 is provided in the second liquid storage tank 8 to ensure that the water level in the second liquid storage tank 8 is tangent to the surface of the second roller 602. The water level regulator 801 contains a water storage bag, and through the principle of communication and atmospheric pressure balance, the liquid level in the second water storage tank is maintained at a set height, ensuring that the second roller 602 is in contact with the solvent surface.

[0039] In one embodiment of the present invention, the first cylinder 102 and the second cylinder 202 are connected by a third connector 9. This arrangement allows for modularization of the cold cutting equipment, improves overall integrity, and facilitates installation.
