Description

Technical Field

[0001] This invention belongs to the field of coating and laminating machine technology, specifically relating to an intelligent multi-purpose UV release film high-speed coating and laminating machine and coating method. Background Technology

[0002] Release film is a type of film product made by coating a polymer layer onto the surface of a plastic film. It possesses release force against organic pressure-sensitive adhesives. Release films share the lightweight and wear-resistant properties of ordinary films, providing isolation and protection for product surfaces. Once the release film's function is exhausted, its release force against the organic pressure-sensitive adhesive allows it to be easily peeled off the product surface, reducing the difficulty of removing film from the product and thus improving production efficiency. The coating process involves applying a coating liquid to the surface of the film product using a coating machine to improve its surface adhesion. In the production of release films, simply changing the type of coating liquid in the coating machine allows for the production of different types of release films, which helps reduce production costs and enhances the product's market competitiveness. Currently, release films require nitrogen cooling for preservation after adhesive coating. This causes the release adhesive to solidify into granules, resulting in an uneven and bumpy surface. Furthermore, the release film needs to be manually cut according to requirements after coating, which consumes a lot of manpower and time, thus increasing costs. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides an intelligent, multi-purpose, high-speed UV release film coating and laminating machine and method. It employs a five-roller coating system for improved coating results and a UV-coating and laminating mechanism for even better results. Specifically, an LED-UV lamp and a UV mercury lamp are installed below the pressing device, providing two types of UV curing lamps that can be pulled out and replaced from the side. The base film for the release adhesive is laminated using a second release film, eliminating the need for nitrogen storage as in conventional methods. Furthermore, the laminated product exhibits a glossy finish with the adhesive inside, resolving the surface unevenness and pitting issues inherent in conventional coating methods. Automatic alignment, fully automatic cutting, auxiliary traction, and tension swing unwinding mechanisms further enhance the coating effect. The machine can also be used as a peeling machine; the first unwinding mechanism remains unwinding, the second unwinding mechanism becomes the first winding mechanism, and the winding mechanism becomes the second winding mechanism.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an intelligent multi-purpose UV release film high-speed coating and laminating machine, comprising two oscillating roller-type tension detection automatic correction unwinding machines, an active corona generator, a five-roller release film coating and laminating machine with adjustable gap, an adhesive feeder, transport rollers, a pressing and cooling device, and a disc winding device; the oscillating roller-type tension detection automatic correction unwinding machines are installed on the production line to unwind the release film from a roll shape to a flat, unfolded state; the active corona generator is installed behind the oscillating roller-type tension detection automatic correction unwinding machines to transfer the flat, unfolded release film to the five-roller release film coating and laminating machine with adjustable gap for power output; the adjustable gap release film...

LED-UV lamps and UV mercury lamps are installed below the pressing device, providing two types of UV curing lamps that can be pulled out and replaced from the side. By using a second layer of release film to laminate the base film coated with release adhesive, nitrogen storage is not required, resulting in a glossy appearance of the adhesive inside the laminated product and a smooth, flat coated surface.

Detailed Implementation

[0018] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present invention.

[0019] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an intelligent multi-purpose UV release film high-speed coating and laminating machine includes two oscillating roller type tension detection automatic correction unwinding machines A, an active corona generator C, a five-roller release film coating and laminating machine B with adjustable gap, an adhesive feeder D, a transport roller E, a pressing and cooling device F, and a disc winding device G. The oscillating roller type tension detection automatic correction unwinding machine A is installed on the production line to unwind the release film from a roll shape to a flat, unfolded state. The active corona generator C is installed behind the oscillating roller type tension detection automatic correction unwinding machine A to transfer the flattened release film to the five-roller release film coating and laminating machine B with adjustable gap, providing power output. The five-roller release film coating and laminating machine B with adjustable gap... Installed behind the active corona machine C, it is used to uniformly coat the transferred release film with adhesive; the adhesive feeder D is installed on one side of the five-roller coating machine B with adjustable gap release film coating and laminating machine, and is used to provide adhesive to the five-roller coating machine B with adjustable gap release film coating and laminating machine; the transport roller E is installed behind the five-roller coating machine B with adjustable gap release film coating and laminating machine, and is used to transport the adhesive-coated release film to the pressing and cooling device F; the pressing and cooling device F is installed behind the transport roller E, and is used to press and cool the release film base film coated with release adhesive and the newly placed second layer release film into a composite product; the disc winding device G is installed behind the pressing and cooling device F, and is used to wind up the composite product. Specifically, firstly, the first oscillating roller tension detection automatic correction unwinding machine A flattens and unfolds the first roll of cylindrical release film. The unfolded release film is then transferred from the oscillating roller tension detection automatic correction unwinding machine A to the five-roller release film coating and laminating machine B with adjustable gap via an active corona generator C. The five-roller release film coating and laminating machine B evenly coats the release film with release adhesive, making it a base film (the base film is a release film with release adhesive evenly coated on one side). Then, the base film is transported to the pressing and cooling device F via transport roller E. At this time, the second oscillating roller tension detection... The automatic web-correcting unwinding machine A flattens out the second roll of cylindrical release film to form the second layer of release film, and then transports it to the pressing and cooling device F. The pressing and cooling device F bonds the base film and the second layer of release film together with release adhesive, and then presses and cools them to form a composite product. Finally, the rotary winding device G winds the composite product into a roll for easy storage and transportation. The composite product does not require nitrogen storage, and the release adhesive inside the product is aesthetically pleasing. The surface of the release film is smooth and flat, the coating speed is faster, and the amount of release adhesive on the coating is less and thinner, improving work efficiency.

[0020] Combination Figure 2 and Figure 3As shown, the device includes a base A-1, a mounting frame A-2 on the base A-1, an automatic unwinding device A-3 mounted on the mounting frame A-2, and an automatic correction mechanism A-4, an automatic cutting mechanism A-5, a tension swing mechanism A-6, and an auxiliary traction mechanism A-7 mounted on one side of the automatic unwinding device A-3. The automatic correction mechanism A-4 is installed at the bottom of the mounting frame A-2 and is used to move the mounting frame A-2 left and right to correct the position of the film. The automatic cutting mechanism A-5 is installed at the upper and lower ends of one side of the automatic unwinding device A-3 and is used to cut the length of the film according to specific values. The tension swing mechanism A-6 is installed behind the automatic unwinding device A-3 and is used to adjust the swing angle according to the tension of the film. The auxiliary traction mechanism A-7 is installed above the tension swing mechanism A-6 and is used to pull the film out of the tension swing mechanism A-6 and into the next device. Specifically, when the film begins to unwind on the automatic unwinding device A-3, if the film is not aligned during unwinding, the automatic correction mechanism A-4 moves the mounting device A-2 left or right to align the film on the automatic unwinding device A-3. The film then enters the tension oscillation mechanism A-6, which adjusts the oscillation angle according to the film tension. Finally, the film is pulled by the auxiliary traction mechanism A-7 into the next device for further processing. When the length of the film unwound on the automatic unwinding device A-3 reaches the specified value, the automatic cutting mechanism A-5 automatically cuts the film on the automatic unwinding device A-3, thus cutting the film to obtain the required length. This invention can automatically unwind, automatically correct deviations, automatically cut, provide auxiliary traction, and adjust the tension oscillation, greatly reducing the labor intensity of workers and improving work efficiency.

[0021] Combination Figure 2 , Figure 3 and Figure 4 As shown, the automatic web guiding mechanism A-4 includes a linear guide rail A-2a located at the bottom of the mounting frame A-2. One side of the linear guide rail A-2a is fixedly connected to the output end of the first servo motor A-2b. The linear guide rail A-2a is connected to a lead screw A-1a mounted on the base A-1. Specifically, when the film begins to unwind on the automatic unwinding device A-3, if the film is not aligned, the first servo motor A-2b is activated, causing its output end to push the mounting frame A-2. This allows the linear guide rail A-2a at the bottom of the mounting frame A-2 to slide and adjust along the lead screw A-1a mounted on the base A-1, aligning the automatic unwinding device A-3 with both sides of the film. The entire process eliminates the need for manual adjustment by workers to align the film with the automatic unwinding device A-3, significantly reducing worker workload and improving work efficiency.

[0022] Combination Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the automatic cutting mechanism A-5 includes a first fixed rod A-5a installed at both ends of the automatic unwinding device A-3. A first cylinder A-5b is installed at both ends of the first fixed rod A-5a. The output end of the first cylinder A-5b is connected to a first rotating block A-5c. A rotating roller A-5d is installed on the rotation axis of the first rotating block A-5c. A cutter A-5e is fixedly installed below the rotating roller A-5d. Specifically, when the length of the film released from the automatic unwinding device A-3 reaches a predetermined value, the first cylinder A-5b is activated, causing the rotating roller A-5d connected to its output end to rotate. The rotating roller A-5d drives the first rotating block A-5c, causing the first rotating block A-5c to rotate along the first fixed rod A-5a and move towards the automatic unwinding device A-3. This also causes the cutter A-5e installed below the rotating roller A-5d to cut the film on the automatic unwinding device A-3. The entire process eliminates the need for workers to manually cut the film, thus greatly reducing the labor intensity of workers and improving work efficiency.

[0023] Combination Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the tension swing mechanism A-6 includes a guide roller A-6a installed behind the automatic unwinding device A-3, a tension roller A-6b disposed below the guide roller A-6a, a second rotating block A-6c fixedly connected to both ends of the rotating shaft of the tension roller A-6b, a second fixed rod A-6d installed on the rotating axis of the second rotating block A-6c, and the middle part of the second rotating block A-6c fixedly connected to the output end of the second cylinder A-6e. Specifically, when the film is on the tension oscillation mechanism A-6, the guide roller A-6a moves the film to the tension roller A-6b below it. The second cylinder A-6e is activated, causing the second rotating block A-6c connected to its output end to oscillate along the axis of the second fixed rod A-6d. This, in turn, drives the tension roller A-6b to oscillate along the axis of the second fixed rod A-6d, causing the film to stretch and contract with the oscillation of the tension roller A-6b. An encoder reads the oscillation angle of the tension roller A-6b, detects its rotation angle, and sends a signal to the automatic unwinding device A-3, thereby adjusting the unwinding speed of the automatic unwinding device A-3 and thus controlling the film tension. The entire process requires no manual intervention, greatly reducing the labor intensity of workers and improving work efficiency.

[0024] Combination Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the auxiliary traction mechanism A-7 includes a fixed traction roller A-7a mounted above the tension swing mechanism A-6 and a movable traction mechanism A-7b. A second servo motor A-7c is mounted on one side of the fixed traction roller A-7a. (Combined with...) Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the movable traction mechanism A-7b includes a third cylinder A-7b1 installed below the fixed traction roller A-7a. The output end of the third cylinder A-7b1 is rotatably connected to one end of the third rotating block A-7b2. A third fixed rod A-7b3 is installed on the rotation axis of the third rotating block A-7b2. The movable traction roller A-7b4 is rotatably installed on the other end of the third rotating block A-7b2. Specifically, when the membrane is on the auxiliary traction mechanism A-7, the second servo motor A-7c is activated, causing its output to drive the fixed traction roller A-7a to rotate. At the same time, the third cylinder A-7b1 is activated, causing its output to drive the third rotating block A-7b2 to rotate along the third fixed rod A-7b3. This causes the movable traction roller A-7b4 to press against the fixed traction roller A-7a. Because the fixed traction roller A-7a rotates, the movable traction roller A-7b4 and the fixed traction roller A-7a rotate relative to each other, thus pulling the membrane between the movable traction roller A-7b4 and the fixed traction roller A-7a, allowing the membrane to be pulled into the next device. The entire process requires no manual handling, greatly reducing the labor intensity of workers and improving work efficiency.

[0025] Combination Figure 2 and Figure 3 As shown, an ultrasonic testing probe A-8 is mounted on the mounting bracket A-2. The ultrasonic testing probe A-8 is designed to detect whether the membrane is misaligned, providing a signal to the automatic correction mechanism A-4, which then adjusts the position of the mounting bracket A-2 to achieve the correction effect.

[0026] Combination Figure 2 and Figure 3 As shown, a control system A-9 is installed on the mounting frame A-2. The control system A-9 can control all the servo motors and cylinders in this invention to achieve automatic unwinding, automatic correction, fully automatic cutting, auxiliary traction, and tension adjustment, which greatly reduces the labor intensity of workers and improves work efficiency.

[0027] Combination Figure 8 , Figure 9 and Figure 10As shown, it includes a fixed frame B-1, on which a glue spraying device B-2, a display system B-3, and a coating device B-4 are mounted. The coating device B-4 includes a metering roller B-5 fixedly mounted on the fixed frame B-1. A transfer steel roller B-6 is connected to the metering roller B-5 in parallel contact. A transfer glue roller B-7 is rotatably connected above the transfer steel roller B-6. A coating steel roller B-8 is rotatably connected diagonally above the transfer glue roller B-7. A coating glue roller B-9 is movably connected above the coating steel roller B-8. A gap adjustment device B-5a is installed at the axial end of each metering roller B-5. Specifically, after the coating unit B-4 has been running for a period of time, when the rollers of the coating unit B-4 need to be cleaned due to the solidification of the release adhesive affecting the coating effect, the transfer steel roller B-6 rotates relative to the transfer rubber roller B-7, the transfer rubber roller B-7 rotates relative to the coating steel roller B-8, and the coating steel roller B-8 rotates relative to the coating rubber roller B-9. This allows for direct cleaning of the transfer rubber roller B-7, the coating steel roller B-8, and the coating rubber roller B-9. Since the metering roller B-5 is fixed, cleaning requires removing both the metering roller B-5 and the transfer steel roller B-9. The gap between metering roller B-5 and transfer steel roller B-6 is increased to allow the release adhesive to fall down, making it easier to clean metering roller B-5. Therefore, gap adjustment device B-5a is needed to increase the gap between metering roller B-5 and transfer steel roller B-6. After cleaning, gap adjustment device B-5a needs to readjust the gap between metering roller B-5 and transfer steel roller B-6 back to the working state, so that the adhesive spraying device B-2 can re-spray the release adhesive into the gap between metering roller B-5 and transfer steel roller B-6, thereby allowing the coating laminating machine to continue working and improving work efficiency.

[0028] Combination Figure 9 , Figure 10 and Figure 11As shown, the gap adjustment device B-5a includes a mounting frame B-1a installed on one side of the fixed frame B-1. An adjusting cylinder B-5a1 is fixedly installed on one side of the outer frame of the mounting frame B-1a. The output end of the adjusting cylinder B-5a1 passes through the outer wall of the mounting frame B-1a and is fixedly connected to the end of the axis of the metering roller B-5. A first slide rail B-1a1 is provided at the bottom of the inner frame of the mounting frame B-1a. A first slider B-5b is provided at the bottom of the end of the axis of the metering roller B-5. The first slider B-5b is connected to the first slide rail B-1a1. Specifically, after the coating unit B-4 has been running for a period of time, when the rollers of the coating unit B-4 need to be cleaned due to the solidification of the release adhesive affecting the coating effect, the transfer roller B-7, coating steel roller B-8, and coating roller B-9 all rotate relative to each other, allowing for direct cleaning. Since the metering roller B-5 is stationary, the gap between the metering roller B-5 and the transfer steel roller B-6 needs to be increased during cleaning to allow the release adhesive in the gap to fall down, making it easier to clean the metering roller B-5. Therefore, it is only necessary to activate the adjusting cylinder B-5a1 of the gap adjusting device B-5a. The output end of the adjusting cylinder B-5a1 moves the axial end of the metering roller B-5, thereby driving the rollers located at the bottom of the axial end of the metering roller B-5. The first slider B-5b slides on the first slide rail B-1a1, thereby increasing the gap between the metering roller B-5 and the transfer steel roller B-6. This facilitates cleaning of the metering roller B-5 and the transfer steel roller B-6. After cleaning, the adjusting cylinder B-5a1 is activated, moving the output end of the adjusting cylinder B-5a1 to the axial end of the metering roller B-5. This causes the first slider B-5b, located at the bottom of the axial end of the metering roller B-5, to slide on the first slide rail B-1a1, thereby decreasing the gap between the metering roller B-5 and the transfer steel roller B-6 until it returns to its original working state, thus improving work efficiency.

[0029] Combination Figure 10 , Figure 11 and Figure 12As shown, the gap adjustment device B-5a also includes a handwheel B-1a2 installed at the bottom of the outer frame of the mounting frame B-1a. A lead screw B-1a3 is fixedly installed on the handwheel B-1a2, penetrating the bottom of the outer frame of the mounting frame B-1a. An inclined block B-1a4 is sleeved on the lead screw B-1a3. An abutting wheel B-5c is provided at the end of the axis of the metering roller B-5. The inclined surface of the inclined block B-1a4 abuts against the abutting wheel B-5c. Specifically, after cleaning, the gap between the metering roller B-5 and the transfer steel roller B-6 is adjusted by the adjusting cylinder B-5a1. However, if the gap does not reach its initial working state after adjustment, fine-tuning of the gap between the metering roller B-5 and the transfer steel roller B-6 is required. Since the fine-tuning distance is very small (approximately 0.3mm to 1mm), the handwheel B-1a2 at the bottom of the outer frame of the mounting frame B-1a is used. Rotating the handwheel B-1a2 drives the rotation of the lead screw B-1a3, causing the inclined block B-1a4 on the lead screw B-1a3 to slide. Because the inclined surface of the inclined block B-1a4 abuts against the contact wheel B-5c at the end of the axis of the metering roller B-5, the gap between the metering roller B-5 and the transfer steel roller B-6 can be fine-tuned, greatly reducing the labor intensity of the workers and improving work efficiency.

[0030] Combination Figure 10 , Figure 11 and Figure 12 As shown, a dial indicator B-1a5 is mounted on the outside of the mounting frame B-1a, and an abutment block B-5b1 is fixedly installed on the first slider B-5b. The tip of the dial indicator B-1a5 abuts against the abutment block B-5b1. Specifically, when fine-tuning the gap between the metering roller B-5 and the transfer steel roller B-6, the tip of the dial indicator B-1a5 mounted on the outside of the mounting frame B-1aa abuts against the abutment block B-5b1 fixedly installed on the first slider B-5b. This causes the dial indicator B-1a5 to extend or retract during fine-tuning, thereby changing the value on the dial indicator B-1a5. When the value on the dial indicator B-1a5 reaches the predetermined value, the fine-tuning is completed, improving the adjustment speed and accuracy, and also increasing work efficiency.

[0031] Combination Figure 7 , Figure 8 and Figure 10As shown, the adhesive spraying device B-2 includes a second slide rail B-2a mounted on a fixed frame B-1. A second slider B-2b is movably connected to the second slide rail B-2a. An adhesive spraying nozzle B-2c is fixedly mounted on the second slider B-2b, facing the gap between the metering roller B-5 and the transfer steel roller B-6. Specifically, when the release adhesive consumption on the coating machine decreases or after cleaning the rollers on the coating machine, the release adhesive is sprayed into the gap between the metering roller B-5 and the transfer steel roller B-6 through the adhesive spraying nozzle B-2c. An infrared liquid level sensor detects the liquid level in the gap between the metering roller B-5 and the transfer steel roller B-6, causing the release adhesive to be automatically replenished. The adhesive spraying nozzle B-2c moves left and right on the second slide rail B-2a via the second slider B-2b, ensuring more even spraying of the release adhesive into the gap between the metering roller B-5 and the transfer steel roller B-6. This results in a more uniform application of the release adhesive onto the film during coating, improving work efficiency.

[0032] Combination Figure 7 and Figure 8 As shown, the display system B-3 includes a display screen mounted on the mounting bracket B-1. The display screen on the mounting bracket B-1 allows operators to clearly observe the coating effect of the coating machine, improving work efficiency.

[0033] Combination Figure 8 and Figure 10 As shown, a motor mounting bracket B-1b is installed on one side of the mounting bracket B-1, and a servo motor B-1c is fixedly mounted on the motor mounting bracket B-1b. The operator observes the coating effect of the coating machine through the display screen B-3a, and controls the speed of the transfer steel roller B-6 and the coating roller by controlling the servo motor B-1c to determine the amount pumped out and consumed. (For example: if the glue pump output and glue output are 1.2g, then the roller speed and coating amount are adjusted to 1.2g).

[0034] Combination Figure 7 and Figure 8 As shown, mounting cabinets B-10 are installed on both sides of the mounting bracket B-1. The mounting cabinets B-10 not only protect the coating device B-4, but also contribute to the aesthetics.

[0035] refer to Figure 1As shown, a coating method is applied to the aforementioned intelligent multi-purpose UV release film high-speed coating and laminating machine. The method includes aligning and flattening the release film using a first oscillating roller type tension detection automatic correction unwinding machine A; transferring the flattened release film to a five-roller release film coating and laminating machine B with adjustable gap using an active corona generator C; supplying release adhesive to the five-roller release film coating and laminating machine B via an adhesive feeder D to uniformly coat the release film and obtain a base film; transporting the base film to a pressing and cooling device F via a transport roller E; aligning and flattening a new release film using a second oscillating roller type tension detection automatic correction unwinding machine A and transporting it to the pressing and cooling device F, thereby pressing the base film and the second layer of release film together to form a composite product; cooling the composite product using LED-UV lamps and UV mercury lamps installed on the pressing and cooling device F; and finally, winding the composite product using a disc winding device G. The five-roller coating process results in superior coating performance. The UV-curing mechanism further enhances the coating and lamination effect. Specifically, LED-UV lamps and UV mercury lamps are installed below the curing unit, offering two types of UV curing lamps that can be pulled out and replaced from the side. A second release film is used to laminate the base film coated with the release adhesive. The LED-UV and UV mercury lamps cool the laminated product, eliminating the need for nitrogen storage. Furthermore, the laminated product exhibits a glossy internal adhesive layer, resulting in a smooth and even coated surface. Automatic alignment, fully automatic cutting, auxiliary traction, and tension-oscillating unwinding mechanisms further improve coating results. It can also be used as a peeling machine; the first unwinding mechanism remains unwinding, the second unwinding mechanism becomes the first winding mechanism, and the winding mechanism becomes the second winding mechanism. Coating speed is faster, reaching 400 meters / min, compared to the conventional 200 meters / min. The coating amount is reduced, resulting in a thinner coating of 0.5g-3g. This improves work efficiency and saves production costs.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
