Description
Technical Field
[0001] The present invention belongs to the technical field of UV film coating, and in particular relates to an intelligent UV film coating compound machine and a coating method. Background Art
[0002] UV film coating and laminating machines are widely used in optical films, electronic films, packaging materials, and other fields. Their core function is to evenly apply UV curable adhesive to the surface of the substrate and form a functional coating through UV curing. With the rapid development of new functional film materials, the market has increasingly higher performance requirements for coating equipment, especially in terms of coating accuracy, production efficiency, and process adaptability.
[0003] However, existing UV film coating and laminating machines still have the following technical defects in terms of structural design and functional adaptability: traditional coating machines are usually only equipped with a single coating method, and UV glues of different viscosities have quite different requirements for the coating process. Slit extrusion coating is suitable for high-viscosity glues, but low-viscosity glues are prone to cast problems; micro-gravure coating is suitable for low-viscosity glues, but the transfer rate of high-viscosity glues is low, resulting in uneven coating. Due to the lack of an integrated design of a multi-mode coating head, the coating module needs to be frequently replaced when producing different products, resulting in long downtime and low production efficiency. In addition, when applying high-viscosity UV glue, existing coating machines are prone to glue accumulation, which requires manual disassembly and cleaning, which is time-consuming and labor-intensive, reducing work efficiency.

[0014] The present invention further describes that one end of a connecting shaft is fixedly installed on one side of the lower section of the first motor sleeve, and the other end of the connecting shaft is connected to a roller. A second sliding groove is also provided on the side plate below the rack, and the roller is located in the second sliding groove, and the two are in rolling cooperation.
[0015] The present invention further describes that the fixing teeth are fixedly arranged on the side plate.
[0016] The present invention further describes that a fourth central shaft is provided through the center of the fixed roller, and both ends of the fourth central shaft are respectively connected to the two side plate shaft holes.
[0017] The present invention further describes that the fixed roller, the first adjustment roller and the lifting roller are commonly connected with a UV film to be coated.
[0018] The present invention further describes that the coating method of the intelligent UV film coating compound machine is characterized by comprising:
[0019] When high-viscosity glue is required for coating, the micro-gravure coating module is located below the slit extrusion coating module, the first adjustment roller is located in the third chute at one end close to the slit extrusion coating module, the second telescopic rod is in a shortened state, the lifting platform is not raised, and the UV film to be coated passes along the fixed roller in sequence to between the slit extrusion coating module and the first adjustment roller, and the slit extrusion coating module performs a coating operation on the UV film to be coated;
[0020] When low-viscosity glue needs to be used for coating, the first motor is first started, and the first central shaft and the gear are driven to rotate through the first coupling. The micro-gravure coating module rotates with the rotation of the first central shaft, and the first telescopic rod is shortened to drive the block to be retracted into the blind groove. During this process, the spring is compressed, and at the same time, the first push rod drives the first piston to move downward. According to the principle of communicating vessels, the volume of the chamber below the first piston in the U-shaped cylinder is reduced, and the gas is squeezed into the chamber where the second piston is located, so that the second piston and the second push rod are pushed up, and the second push rod drives the first floating tooth to rise along the fourth slide groove through the connecting rod and be flush with the fixed tooth. At this time, the gear is engaged with the first floating tooth, and the micro-gravure coating module is driven by the first central shaft to slide along the first slide groove to the other end to the fixed tooth and continue to engage and slide with it;
[0021] When the micro-gravure coating module slides to the side of the stopper at the other end, the stopper descends. The adjustment principle is the same as that of the stopper, so that the micro-gravure coating module slides over the stopper. When the micro-gravure coating module slides along the first chute, the roller rolls synchronously along the second chute.
[0022] Next, the first telescopic rod drives the stopper to rise, and the adjustment mechanism operates in the same manner as when the stopper descends, but in the opposite direction of movement, thereby causing the second floating tooth to descend along the fourth chute, disengaging the second floating tooth from the fourth chute, and the lifting platform drags the paint trough upward;
[0023] Afterwards, the second motor is started to drive the first conveyor roller to rotate through the second coupling and the third central shaft, and the first conveyor roller drives the conveyor belt to transmit. The conveyor belt drives the second central shaft and the first adjustment roller to slide to the other end of the third slide groove through the slider. The second motor is turned off. At this time, the first adjustment roller is located above the micro-gravure coating module, and the second telescopic rod is extended to drive the lifting roller to rise through the shaft frame and the fifth central shaft to tension the UV film to be coated. Since the gear is disengaged from the second floating tooth, the first motor drives the micro-gravure coating module to rotate, and at the same time, the coating is dipped from the coating tank below, thereby performing the coating operation.
[0024] While the micro-gravure coating module is performing the coating operation, a cleaning liquid is injected into the flow channel of the slit extrusion coating module to clean it. The used cleaning liquid will fall into the sewage tank from the flow channel of the first adjustment roller. When it is necessary to switch to the slit extrusion coating module for coating operation, the movement principle of each component is the same as the above principle, and the movement direction is opposite. When the micro-gravure coating module is located below the slit extrusion coating module, the cleaning liquid is sprayed on it by the nozzle while the micro-gravure coating module rotates to perform cleaning work.
[0025] Compared with the prior art, the present invention has the following beneficial effects:
[0026] (1) By providing a slit extrusion coating module and a micro-gravure coating module, the coating mode can be switched according to the viscosity of the UV glue. The slit extrusion coating is suitable for high-viscosity glue to avoid the problem of casting, and the micro-gravure coating is suitable for low-viscosity glue to improve the transfer rate and ensure the coating uniformity. This multi-mode coating design overcomes the defect of the single coating method in the existing technology that it is difficult to take into account the coating quality of glues with different viscosities, and significantly improves the coating quality and efficiency;
[0027] (2) By setting up a coating module switch or after the coating operation is completed, the coating module can be automatically cleaned, avoiding the tedious steps of manual disassembly and cleaning, saving labor costs and time costs, reducing equipment maintenance costs, and improving production efficiency.

DETAILED DESCRIPTION
[0040] The following is a non-limiting detailed description of the technical solutions of the present invention in conjunction with preferred embodiments and the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.
[0041] refer to Figures 1 to 10 , the embodiment of the present invention provides an intelligent UV film coating compound machine and coating method, such as Figure 1 and Figure 2 As shown, the intelligent UV film coating laminating machine and coating method include a workbench 1, with side panels 11 fixedly provided on opposite sides of the workbench 1. A slit extrusion coating module 2 is fixedly provided between the two side panels 11. A micro-gravure coating module 3 is provided below the slit extrusion coating module 2. Each of the side panels 11 is provided with a first chute 111, and a rack 112 is provided below the first chute 111 of one of the side panels 11. The slit extrusion coating module 2 is used for coating operations when using high-viscosity adhesives, and the micro-gravure coating module 3 is used for coating operations when using low-viscosity adhesives. By switching the coating mode according to the viscosity of the coating, it is beneficial to improve the coating efficiency and coating quality.
[0042] like Figure 1 and Figure 6As shown, a first central shaft 31 is provided through the center of the micro-gravure coating module 3. The ends of the first central shaft 31 slideably engage with the two first chutes 111, respectively. A gear 32 is provided on the end of the first central shaft 31 closest to the rack 112 and connected to a power source. The gear 32 meshes with the rack 112. The power source drives the micro-gravure coating module 3 to slide along the first chutes 111, enabling it to move between a position below and a position away from the slit-extrusion coating module 2.
[0043] like Figure 5 and Figure 8 As shown, both ends of the first chute 111 are provided with stoppers 36, and opposite sides of the two stoppers 36 are adapted to the first central axis 31. The first chute 111 is provided with a blind groove 1111 below the stoppers 36. The stoppers 36 are used to position the micro-gravure coating module 3 after the micro-gravure coating module 3 slides to one end of the first chute 111.
[0044] like Figure 8 As shown, a first telescopic rod 361 and the upper end of a spring 362 are fixedly disposed below each stopper 36. The lower ends of the first telescopic rod 361 and the spring 362 are fixedly disposed on the lower surface of the blind slot 1111. An adjustment mechanism 37 is also fixedly disposed below the stopper 36. The first telescopic rod 361 is used to drive the stopper 36 to rise or fall, and the spring 362 is used to assist the first telescopic rod 361 in supporting the stopper 36.
[0045] like Figure 8 As shown, the adjustment mechanism 37 includes a first push rod 371 fixed below the stopper 36. The first push rod 371 extends downward through a U-shaped cylinder 373 and is fixedly connected to a first piston 372. The U-shaped cylinder 373 is a U-shaped structure with two chambers connected by a channel. The first piston 372 is slidably connected to one chamber of the U-shaped cylinder 373, and a second piston 374 is slidably connected to the other chamber of the U-shaped cylinder 373. A second push rod 375 is fixedly connected below the second piston 374 and extends downward through the U-shaped cylinder 373. When the first telescopic rod 361 is used to drive the stopper 36 to rise or fall, the first push rod 371 drives the first piston 372 to rise or fall, changing the volume of the two chambers in the U-shaped cylinder 373, thereby pushing the second piston 374 to drive the second push rod 375 to rise or fall.
[0046] like Figure 1 、 Figure 6 and Figure 9As shown, the rack 112 includes a first floating tooth 1121, a fixed tooth 1122, and a second floating tooth 1123. A connecting rod 3751 is fixedly connected to one side of the lower end of each of the two second push rods 375. The other ends of the two connecting rods 3751 are fixedly connected to the first floating tooth 1121 and the second floating tooth 1123, respectively. Two fourth sliding grooves 115 are defined on the side panel 11, and the two connecting rods 3751 slideably engage with the respective fourth sliding grooves 115.
[0047] The lifting and lowering of the second push rod 375 drives the lifting and lowering of the first floating tooth 1121 or the second floating tooth 1123, thereby controlling the engagement and disengagement of the gear 32 with the rack 112, and further controlling the sliding and rotation of the micro-gravure coating module 3. When the micro-gravure coating module 3 slides through the stopper 36, the second push rod 375 drives the first floating tooth 1121 or the second floating tooth 1123 to rise along the fourth slide groove 115 via the connecting rod 3751, thereby aligning the first floating tooth 1121 or the second floating tooth 1123 with the fixed tooth 1122, thereby achieving the engagement and passing of the gear 32 on the first floating tooth 1121 or the second floating tooth 1123.
[0048] When the stopper 36 is raised to position the micro-gravure coating module 3, the first push rod 371 rises accordingly, and the same principle applies to its descent. Ultimately, the second push rod 375 drives the first floating tooth 1121 or the second floating tooth 1123 to descend along the fourth chute 115 via the connecting rod 3751. The first floating tooth 1121 or the second floating tooth 1123 disengages from the gear 32, ensuring that the micro-gravure coating module 3 rotates after being positioned. This ensures that the sliding and rotation of the micro-gravure coating module 3 do not interfere with each other, thereby improving the flexibility and automation of the coating process.
[0049] In certain preferred embodiments, Figure 2 and Figure 3As shown, a first adjustment roller 4 and a fixed roller 5 are disposed between the two side panels 11. A sewage trough 7 is also disposed on the workbench 1 below the slit extrusion coating module 2. A bracket 10 is fixedly disposed on one side of the sewage trough 7 on the workbench 1. A nozzle 101 is fixedly disposed on one side of the bracket 10, and the nozzle 101 faces the micro-gravure coating module 3. A lifting platform 9 is fixedly disposed on the other side of the sewage trough 7 on the workbench 1. A coating trough 8 is fixedly disposed on the lifting platform 9, and the coating trough 8 is located directly below the end of the first chute 111 away from the slit extrusion coating module 2. Second telescopic rods 63 are also fixedly disposed on opposite sides of the workbench 1. A shaft bracket 62 is fixedly disposed above each second telescopic rod 63. The two shaft brackets 62 are jointly penetrated by a fifth central shaft 61, and the lifting roller 6 is sleeved on the fifth central shaft 61.
[0050] The first adjustment roller 4, the fixed roller 5, and the lifting roller 6 are used to support and position the UV film and achieve tension control during the coating process. The coating tank 8 is used to hold low-viscosity coatings, the nozzle 101 is used to clean the micro-gravure coating module 3, and the sewage tank 7 is used to collect cleaning waste liquid.
[0051] In certain preferred embodiments, Figure 4 As shown, each side plate 11 is provided with a third chute 114, within which a slider 42 is slidably mounted. A second central shaft 41 is passed through both sliders 42, and the first adjustment roller 4 is sleeved onto the second central shaft 41. A conveyor belt 43 is connected to each side of the slider 42, passing through the side plate 11. A first conveyor roller 44 is also rotatably engaged within the conveyor belt 43, and a third central shaft 441 is passed through the center of the first conveyor roller 44. As the slider 42 slides within the third chute 114, the first adjustment roller 4 is simultaneously driven to slide by the second central shaft 41, thereby enabling movement between an end closer to the slit extrusion coating module 2 and an end further away from the slit extrusion coating module 2.
[0052] In certain preferred embodiments, Figure 7As shown, one end of the third central shaft 441 is connected to one end of a second coupling 442, and the other end of the second coupling 442 is connected to a second motor 443. The second motor 443 is fixedly mounted within a second motor housing 444, which is fixedly mounted on the side plate 11. The second motor 443 serves as a power source, driving the first conveyor roller 44 to rotate via the second coupling 442 and the third central shaft 441. The first conveyor roller 44 drives the conveyor belt 43, which drives the second central shaft 41 and the first adjustment roller 4 to slide via the slider 42, thereby achieving movement of the first adjustment roller 4.
[0053] In certain preferred embodiments, Figure 6 As shown, one end of the first central shaft 31 near the rack 112 is connected to one end of a first coupling 33, and the other end of the first coupling 33 is connected to a first motor 34, which is fixedly mounted in a first motor housing 35. The first motor 34 acts as a power source to rotate the first central shaft 31 and the gear 32 through the first coupling 33, thereby driving the micro-gravure coating module 3 to slide or rotate.
[0054] In certain preferred embodiments, Figure 6 As shown, one end of a connecting shaft 351 is fixedly mounted on one side of the lower section of the first motor housing 35. The other end of the connecting shaft 351 is connected to a roller 352. A second chute 113 is further defined on the side panel 11 below the rack 112. The roller 352 is positioned within the second chute 113 and engages in rolling engagement. The engagement of the roller 352 and the second chute 113 ensures meshing of the gear 32 with the rack 112, thereby enabling smooth sliding of the micro-gravure coating module 3.
[0055] In certain preferred embodiments, Figure 1 As shown, the fixing teeth 1122 are fixedly arranged on the side plate 11 .
[0056] In certain preferred embodiments, Figure 2 As shown, a fourth central shaft 51 is passed through the center of the fixed roller 5 , and both ends of the fourth central shaft 51 are connected to the shaft holes of the two side plates 11 respectively.
[0057] In certain preferred embodiments, Figure 10 As shown, the fixed roller 5, the first adjusting roller 4 and the lifting roller 6 are commonly connected to the UV film 100 to be coated. The fixed roller 5, the first adjusting roller 4 and the lifting roller 6 are used to fix and support the UV film 100 to be coated.
[0058] In the above embodiment, the coating method of the intelligent UV film coating compound machine is characterized by comprising:
[0059] refer to Figure 10 When high-viscosity glue is required for coating, the micro-gravure coating module 3 is located below the slit extrusion coating module 2, the first adjustment roller 4 is located in the third slide 114 near one end of the slit extrusion coating module 2, the second telescopic rod 63 is in a shortened state, the lifting platform 9 is not raised, and the UV film 100 to be coated passes along the fixed roller 5 in sequence between the slit extrusion coating module 2 and the first adjustment roller 4, and the slit extrusion coating module 2 performs a coating operation on the UV film 100 to be coated.
[0060] When low-viscosity glue is needed for coating, the first motor 34 is first started, and the first central shaft 31 and the gear 32 are driven to rotate through the first coupling 33. The micro-gravure coating module 3 rotates with the rotation of the first central shaft 31, and the first telescopic rod 361 is shortened to drive the block 36 back into the blind groove 1111. During this process, the spring 362 is compressed, and the first push rod 371 drives the first piston 372 to move downward. According to the principle of communicating vessels, the volume of the chamber below the first piston 372 in the U-shaped cylinder 373 is reduced. The gas is squeezed into the chamber where the second piston 374 is located, so that the second piston 374 and the second push rod 375 are pushed up, and the second push rod 375 drives the first floating tooth 1121 to rise along the fourth slide groove 115 and be flush with the fixed tooth 1122 through the connecting rod 3751. At this time, the gear 32 is engaged with the first floating tooth 1121, and the micro-gravure coating module 3 is driven by the first center axis 31 to slide along the first slide groove 111 to the other end to the fixed tooth 1122 and continue to engage and slide with the fixed tooth 1122.
[0061] When the micro-gravure coating module 3 slides to the stopper 36, the stopper 36 descends. The adjustment principle is the same as that of the stopper 36 near the slot die coating module 2, so that the micro-gravure coating module 3 slides past the stopper 36. During the sliding process of the micro-gravure coating module 3 along the first chute 111, the roller 352 rolls synchronously along the second chute 113.
[0062] Then, the first telescopic rod 361 drives the block 36 to rise, and the components of the adjustment mechanism 37 have the same working principle as the block 36 when descending, but the movement direction is opposite, so that the second floating tooth 1123 descends along the fourth slide groove 115, so that the second floating tooth 1123 is disengaged from the fourth slide groove 115, and the lifting platform 9 drags the paint trough 8 to rise.
[0063] Afterwards, the second motor 443 is started to drive the first conveying roller 44 to rotate through the second coupling 442 and the third central shaft 441, and the first conveying roller 44 drives the conveyor belt 43 to transmit. The conveyor belt 43 drives the second central shaft 41 and the first adjusting roller 4 to slide to the other end of the third slide groove 114 through the slider 42, and the second motor 443 is turned off. At this time, the first adjusting roller 4 is located above the micro-gravure coating module 3, and the second telescopic rod 63 is extended to drive the lifting roller 6 to rise through the shaft frame 62 and the fifth central shaft 61 to tension the UV film 100 to be coated (that is, the UV film 100 to be coated passes between the micro-gravure coating module 3 and the first adjusting roller 4 along the fixed roller 5, and then is transmitted along the lifting roller 6). Since the gear 32 is disengaged from the second floating tooth 1123, the first motor 34 drives the micro-gravure coating module 3 to rotate, and at the same time, dips the coating from the coating tank 8 below to perform the coating operation.
[0064] While the micro-gravure coating module 3 is performing the coating operation, a cleaning liquid is injected into the flow channel of the slit extrusion coating module 2 to clean it. The used cleaning liquid will fall into the sewage tank 7 from the flow channel of the first adjustment roller 4.

10. A coating method for an intelligent UV film coating laminating machine according to any one of claims 1 to 9, characterized in that: include: When high-viscosity glue is required for coating, the micro-gravure coating module is located below the slit extrusion coating module, the first adjustment roller is located in the third chute at one end close to the slit extrusion coating module, the second telescopic rod is in a shortened state, the lifting platform is not raised, and the UV film to be coated passes along the fixed roller in sequence to between the slit extrusion coating module and the first adjustment roller, and the slit extrusion coating module performs a coating operation on the UV film to be coated; When low-viscosity glue needs to be used for coating, the first motor is first started, and the first central shaft and the gear are driven to rotate through the first coupling. The micro-gravure coating module rotates with the rotation of the first central shaft, and the first telescopic rod is shortened to drive the block to be retracted into the blind groove. During this process, the spring is compressed, and at the same time, the first push rod drives the first piston to move downward. According to the principle of communicating vessels, the volume of the chamber below the first piston in the U-shaped cylinder is reduced, and the gas is squeezed into the chamber where the second piston is located, so that the second piston and the second push rod are pushed up, and the second push rod drives the first floating tooth to rise along the fourth slide groove through the connecting rod and be flush with the fixed tooth. At this time, the gear is engaged with the first floating tooth, and the micro-gravure coating module is driven by the first central shaft to slide along the first slide groove to the other end to the fixed tooth and continue to engage and slide with it; When the micro-gravure coating module slides to the side of the stopper at the other end, the stopper descends. The adjustment principle is the same as that of the stopper, so that the micro-gravure coating module slides over the stopper. When the micro-gravure coating module slides along the first chute, the roller rolls synchronously along the second chute. Next, the first telescopic rod drives the stopper to rise, and the adjustment mechanism operates in the same manner as when the stopper descends, but in the opposite direction of movement, thereby causing the second floating tooth to descend along the fourth chute, disengaging the second floating tooth from the fourth chute, and the lifting platform drags the paint trough upward; Afterwards, the second motor is started to drive the first conveyor roller to rotate through the second coupling and the third central shaft, and the first conveyor roller drives the conveyor belt to transmit. The conveyor belt drives the second central shaft and the first adjustment roller to slide to the other end of the third slide groove through the slider. The second motor is turned off. At this time, the first adjustment roller is located above the micro-gravure coating module, and the second telescopic rod is extended to drive the lifting roller to rise through the shaft frame and the fifth central shaft to tension the UV film to be coated. Since the gear is disengaged from the second floating tooth, the first motor drives the micro-gravure coating module to rotate, and at the same time, the coating is dipped from the coating tank below, thereby performing the coating operation. While the micro-gravure coating module is performing the coating operation, a cleaning liquid is injected into the flow channel of the slit extrusion coating module to clean it. The used cleaning liquid will fall into the sewage tank from the flow channel of the first adjustment roller. When it is necessary to switch to the slit extrusion coating module for coating operation, the movement principle of each component is the same as the above principle, and the movement direction is opposite. When the micro-gravure coating module is located below the slit extrusion coating module, the cleaning liquid is sprayed on it by the nozzle while the micro-gravure coating module rotates to perform cleaning work.
