[0001] This invention relates to the field of coating technology, and in particular to an oil coating equipment. Background Technology

[0002] Typically, after printing on outdoor advertisements and car stickers, the surface ink is not waterproof, sun-proof, or scratch-resistant, requiring a protective film to achieve sun protection, waterproofing, scratch resistance, and enhance the three-dimensionality of the image. The current standard method involves rolling and bonding a layer of polyethylene (PE) / thermoplastic polyurethane (TPU) solid film.

[0003] However, under the above-mentioned lamination process, the surface of the laminated product is usually prone to bubbles, peeling, cracking, delamination, etc., and has poor sun protection, waterproof and scratch resistance. The adhesive application is also cumbersome and time-consuming, which leads to a short product lifespan, poor extensibility, and seriously affects the quality of the image. Summary of the Invention

Liquid oil is sprayed onto the surface of a first rotating roller via a coating component. As the first rotating roller rotates, its surface uniformly absorbs the liquid oil coating. The first and second rotating rollers then clamp the roll material to be coated, ensuring uniform coating application. The oil-curing mechanism then cures the coated image, rapidly forming a film. Utilizing both heat curing and ultraviolet curing units, this invention allows for rapid switching between liquid resin oil and liquid UV oil coating modes. Compared to traditional coating processes using rolling and adhesive solid film, this invention uses a dual-purpose liquid oil and liquid UV oil coating curing method to form a transparent solid film on the surface of the image on the roll material, seamlessly integrating with the image carrier. This results in a strong three-dimensional effect and effectively solves problems such as bubbles, curling, cracking, delamination, short service life, poor extensibility, and difficult application.

[0034] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0035] This invention provides an oil coating device, such as... Figure 1 The machine includes a frame 1, and an unwinding mechanism 2, a winding mechanism 3, a coating mechanism 4, and an oil coating and curing mechanism 5, all mounted on the frame 1. The coating mechanism 4 and the oil coating and curing mechanism 5 are positioned between the unwinding mechanism 2 and the winding mechanism 3. Preferably, the coating mechanism 4 and the oil coating and curing mechanism 5 are both located at the top of the frame 1, while the unwinding mechanism 2 and the winding mechanism 3 are both located near the bottom of the frame 1. In practical applications, the roll of material to be coated is mounted on the unwinding mechanism 2, and one end of the roll is pulled out and passed sequentially through the coating mechanism 4 and the oil coating and curing mechanism 5 before being wound onto the winding mechanism 3. This facilitates the transfer of the roll of material to be coated from the unwinding mechanism 2 to the winding mechanism 3 as the equipment operates, completing the coating process.

[0036] Combination Figure 2As shown, the coating mechanism 4 includes a first rotating roller 41, a second rotating roller 42, and a coating assembly 43 mounted on the frame 1. A clamped oiling gap is formed between the first rotating roller 41 and the second rotating roller 42 for the roll material to be coated to pass through. The coating assembly 43 is used to apply coating to the roller surface of the first rotating roller 41. The oiling and curing mechanism 5 includes a heat curing unit 51 and an ultraviolet curing unit 52 mounted on the frame 1. The heat curing unit 51 and the ultraviolet curing unit 52 are used to cure the coating on the roll material, and the roll material to be coated is conveyed from the unwinding mechanism 2 along the coating mechanism 4 and the oiling and curing mechanism 5 to the winding mechanism 3 for winding. Preferably, the heat curing unit 51 and the ultraviolet curing unit 52 each have an oiling and curing surface close to the coating surface of the roll material. In practical applications, the roll material to be coated is first conveyed from the unwinding mechanism 2 to the coating mechanism 4. The surface of the first rotating roller 41, which adsorbs the liquid oil coating, comes into contact with the image of the roll material to be coated for uniform coating. After coating, the roll material is conveyed to the coating and curing mechanism 5. Based on the contact between the coating and curing surfaces of the heating curing unit 51 and the ultraviolet curing unit 52 and the image of the roll material, the heating curing unit 51 and the ultraviolet curing unit 52 are switched to cure the liquid oil and liquid UV oil on the coated roll in sequence and form a transparent solid film. Finally, the coated roll material is wound up on the winding mechanism 3.

[0037] Preferably, the first rotating roller 41 is a rubber-coated roller so that the surface of the roller body of the first rotating roller 41 can absorb liquid oil coating. The second rotating roller 42 is a metal roller. The rotating roller is typically composed of a roller body and end shafts extending from both ends of the roller body, all integrally formed.

[0038] With the above-described structure, an oil-curing film-forming process is employed. Liquid oil paint is supplied to the surface of the first rotating roller 41 via the paint assembly 43. As the first rotating roller 41 rotates, its surface uniformly absorbs the liquid oil paint, allowing for simultaneous forward transport of the roll material and uniform coating of the image on the roll. Utilizing both heat-curing unit 51 and ultraviolet-curing unit 52, rapid switching between liquid resin oil and liquid UV oil coating modes is achieved. This dual-purpose liquid oil and liquid UV oil coating curing method forms a transparent solid film on the surface of the image on the roll material, seamlessly integrating with the image carrier. The coating exhibits a strong three-dimensional effect and effectively improves the lifespan and extensibility of the coated roll.

[0039] Furthermore, combined Figure 3As shown, the coating mechanism 4 also includes an oil-passing roller 44, an oil recovery tank 45, and a guide roller 46 mounted on the frame 1. An oil-passing gap is formed between the oil-passing roller 44 and the first rotating roller 41. Preferably, the oil-passing roller 44 can be located on the horizontal side of the first rotating roller 41. The oil outlet of the coating component 43 corresponds to the oil-passing roller 44, and preferably, the oil outlet of the coating component 43 can be located directly above the oil-passing gap. The oil recovery tank 45 is located below the oil-passing gap, and the oil recovery tank 45 is inclined, with an oil discharge port at the downward inclined end of the oil recovery tank 45. With this structure, the oil coating flows from top to bottom through the oil-passing gap between the oil-passing roller 44 and the first rotating roller 41. With the assistance of the oil-passing roller 44, the oil coating can be evenly coated on the surface of the first rotating roller 41, further ensuring that the first rotating roller 41 applies a uniform coating to the image of the roll material to be coated. Based on the above, the oil drain port and the oil collection tank can be connected by a pipeline. The inclined liquid oil recovery tank 45 allows excess paint flowing through the oil gaps during the initial operation of the equipment, as well as paint overflowing from the roll material during coating, to flow into the liquid oil recovery tank 45 and then collect at the oil drain port for recycling into the oil collection tank, thus realizing the recycling of liquid oil.

[0040] Preferably, the oiling roller 44 is a metal roller that can rotate or not rotate, and will not absorb paint, allowing the liquid oil paint to flow through the roller surface of the oiling roller 44 to the first rotating roller 41, where it will be absorbed onto the roller surface of the first rotating roller 41. The first rotating roller 41, the second rotating roller 42, and the oiling roller 44 can rotate synchronously via a motor drive and gear transmission. A fine-tuning structure can be installed on the oiling roller 44 to adjust the gap between the first rotating roller 41 and the oiling roller 44, thereby precisely controlling the amount of oil applied.

[0041] Furthermore, the guide rollers 46 are located on the infeed side and the outfeed side of the first rotating roller 41, respectively. This structure guides the conveying direction of the roll material to be coated, ensuring that the tension of the roll material remains constant during conveying. Preferably, the second rotating roller 42 may be located below the first rotating roller 41.

[0042] Furthermore, combined Figure 1 and Figure 4As shown, the coating assembly 43 includes an electromagnetic oil supply pump, an oil delivery pipe 431, and an oil outlet regulating valve 432. The oil delivery pipe 431 is fixed on the frame 1, and preferably, the oil delivery pipe 431 is located above the oil passage gap. Multiple oil outlet regulating valves 432 are connected to the body of the oil delivery pipe 431, and the oil outlet of the oil outlet regulating valve 432 corresponds to the oil passage roller 44. Preferably, the oil outlet regulating valve 432 supplies liquid oil coating to the oil passage gap. The electromagnetic oil supply pump is connected to the oil delivery pipe 431 via a pipe. This structure, with multiple oil outlet regulating valves 432 arranged along the length of the oil passage gap, precisely controls the oil supply at each location, facilitating the coating assembly 43 to provide uniform liquid oil coating to the oil passage gap from top to bottom, thereby further ensuring that the liquid oil coating can be uniformly coated on the surface of the first rotating roller 41. Preferably, the electromagnetic oil supply pump can be controlled by PLC software to set the real-time oil supply flow rate according to the coating speed, thereby reducing liquid oil waste.

[0043] Furthermore, looking back Figure 3 A scraping mechanism 47 is provided on one side of the second rotating roller 42. The scraping mechanism 47 includes a scraper rod 471 and a scraper blade 472. The scraper rod 471 is fixed to the frame 1, and the scraper blade 472 is fixed to the scraper rod 471, with the scraper blade 472 in contact with the roller surface of the second rotating roller 42. Preferably, a scraper blade 472 is provided at each end of the roller body of the second rotating roller 42. With this structure, the scraper blade 472 scrapes the roller surface of the second rotating roller 42 to remove edge material and prevent paint from being sprayed onto the edge of the equipment casing.

[0044] Furthermore, combined Figure 4 and Figure 5 As shown, the coating mechanism 4 also includes a coating drive unit 48 and a spacing adjustment unit 49. The coating drive unit 48 includes a first drive motor 481, a first drive gear 482, and a first driven gear 483. The first drive motor 481 is fixed on the frame 1, and its output end is connected to one end of the first rotating roller 41. The first drive gear 482 is fixed to the end shaft of the first rotating roller 41, and the first driven gear 483 is fixed to the end shaft of the second rotating roller 42. The first drive gear 482 and the first driven gear 483 are meshed together. With this structure, the rotation of the first rotating roller 41 drives the rotation of the second rotating roller 42 by the synchronous transmission of the motor and gears. This allows the first rotating roller 41 to uniformly coat the image on the roll material while the first and second rotating rollers 42 simultaneously convey the roll material to be coated.

[0045] The spacing adjustment unit 49 includes a first linear push rod 491 and a connecting plate 492. The first linear push rod 491 is mounted on the frame 1. One end of the connecting plate 492 is rotatably connected to the frame 1, and the push rod end of the first linear push rod 491 is hinged to the connecting plate 492. The end shaft of the second rotating roller 42 is connected to the free end of the connecting plate 492. Preferably, a set of spacing adjustment units 49 are respectively provided on the end shafts at both ends of the second rotating roller 42. With this structure, the first linear push rod 491 drives the connecting plate 492 to rotate around the hinged end, thereby moving the position of the second rotating roller 42. With synchronous gear transmission, the gap between the first rotating roller 41 and the second rotating roller 42 can be adjusted without shutting down the equipment, thus enabling precise control of the oil coating thickness.

[0046] Furthermore, looking back Figure 2 The heating and curing unit 51 includes a rotating heating plate 511 and a second linear push rod 512. The rotating heating plate 511 is rotatably connected to the frame 1. The second linear push rod 512 is mounted on the frame 1, and its push rod end is hinged to the rotating heating plate 511, so that the heating surface of the rotating heating plate 511 approaches or moves away from the coated roll material. Preferably, a second linear push rod 512 is provided on each side of the frame 1 to facilitate the rotation of the rotating heating plate 511 by pushing it. With this structure, the rotatable rotating heating plate 511 can be rotated open when heating is stopped, when inspecting the roll material to be coated, or during other operations, to prevent the rotating heating plate 511 from continuously heating and damaging the roll material to be coated.

[0047] Preferably, the rotating heating plate 511 may be equipped with a heat source, heat insulation cotton, an electric coupling temperature sensor, and a constant temperature controller to achieve constant temperature heating control of the rotating heating plate 511. The heat source can be a heating wire, a heating lamp, or an electric heating tube. Furthermore, the rotating heating plate 511 can be tilted upwards by 30°-45° for easy loading, unloading, and maintenance.

[0048] The ultraviolet curing unit 52 includes an ultraviolet lamp box and a detachable bracket. The detachable bracket is mounted on the frame 1, and the ultraviolet lamp box is fixed on the detachable bracket. Preferably, the ultraviolet lamp box contains an LED ultraviolet light source, and the oil-coated curing surface of the ultraviolet lamp box is a transparent surface through which the light source can pass. With this structure, the ultraviolet lamp box is fixed on the frame 1 using the detachable bracket, facilitating the assembly and disassembly of the ultraviolet lamp box. Thus, when switching to liquid UV oil curing, the rotating heating plate 511 is opened by the second linear push rod 512, and the ultraviolet lamp box is fixed at the opened position of the rotating heating plate 511 to replace the rotating heating plate 511 and achieve the curing of liquid UV oil.

[0049] Preferably, the top of the frame 1 is provided with two horizontally arranged heating and curing units 51, and the two heating and curing units 51 rotate and open in opposite directions. In this case, one of the heating and curing units 51 can be used to switch with the ultraviolet curing unit 52 to achieve dual-purpose operation and reduce the user's equipment cost.

[0050] As described above, cooling fans 53 are respectively provided on the rotating heating plate 511 and the ultraviolet lamp box to dissipate heat from the rotating heating plate 511 and the ultraviolet lamp box, thereby ensuring safe operation of the equipment and reducing energy consumption. Preferably, a return air duct can be provided on the rotating heating plate 511 and the ultraviolet lamp box to achieve heat recovery.

[0051] Furthermore, combined Figure 2 and Figure 6 As shown, the oil coating equipment also includes an edge trimming mechanism 6 located between the oil coating and curing mechanism 5 and the winding mechanism 3. Specifically, the edge trimming mechanism 6 is located directly above the winding mechanism 3. The edge trimming mechanism 6 includes a fixed shaft 61, a blade holder 62, a second drive motor 63, and an edge detection sensor 64. The fixed shaft 61 is mounted on the frame 1, and the blade holder 62 is fixed on the fixed shaft 61, with blade holders 62 respectively located near both sides of the roll material. The blade holder 62 has edge trimming blades that contact the roll material. The second drive motor 63 is fixed on the frame 1 and connected to the fixed shaft 61. The edge detection sensor 64 is fixed to the end of the fixed shaft 61, and a limiting groove is formed on the edge detection sensor 64 for the side edge of the roll material to pass through. This structure utilizes an edge-tracking detection sensor 64 to detect the positions of the two side edges of the coated roll in real time and sends feedback signals to the control center. The control center then controls the second drive motor 63 to rotate the fixed shaft 61, thereby automatically adjusting the cutting position of the blade holder 62 in real time. This ensures that the cutting blade rotates to contact the coated roll, achieving automatic edge tracking and correction. This allows for automatic edge trimming of the coated roll as needed. Furthermore, a limiting groove limits and fixes the edge lines of the coated roll to ensure that the cutting blade can properly trim the coated roll.

[0052] As described above, preferably, the oil coating equipment of this embodiment of the invention is also based on a control center, which includes a PLC and a touch screen 11 that are electrically connected to each other. The PLC controls the operation of the unwinding mechanism 2, the winding mechanism 3, the coating mechanism 4, the oil coating and curing mechanism 5, and the edge trimming mechanism 6 through a preset program. The touch screen 11 is fixed on the frame 1 and is used to set the operating parameters of each mechanism, including but not limited to the quick setting of coating speed, oil supply flow rate, heating curing, ultraviolet curing, the on and off of the cooling fan 53, and other parameter settings, making production more suitable for flexible manufacturing.

[0053] Furthermore, such as Figures 7-9As shown, both the unwinding mechanism 2 and the winding mechanism 3 include a roll material fixing unit 7. The roll material fixing unit 7 includes a roll material rotating roller 71, a second driving gear 72, a second driven gear 73, and a third drive motor 74. The third drive motor 74 is fixed on the frame 1, the second driving gear 72 is fixed on the output end of the third drive motor 74, and the second driven gear 73 is fixed on the first end shaft of the roll material rotating roller 71, and the second driving gear 72 and the second driven gear 73 are meshed together. With this structure, the rotation of the roll material rotating roller 71 is achieved by using a motor drive and gear synchronous transmission. In specific applications, the roll material rotating roller 71 (unwinding rotating roller) in the unwinding mechanism 2 unwinds the roll material to be coated, and the roll material rotating roller 71 (winding rotating roller) in the winding mechanism winds up the coated roll material. This allows the roll material to be coated to be cured into a film from the unwinding mechanism 2, through the coating mechanism 4 and the oil curing mechanism 5, and then through the edge trimming mechanism 6 according to the set program. Finally, it is conveyed to the winding mechanism 3 for winding.

[0054] Preferably, the roll material rotating roller 71 includes a roller body and a first end shaft and a second end shaft integrally formed at both ends of the roller body.

[0055] A swing locking mechanism 8 is provided between the roll material rotating roller 71 and the frame 1. The swing locking mechanism 8 includes a third linear push rod 81, a baffle 82, a linkage 83, and a limiting bracket 85. A notch 84 is provided on the frame for the first end shaft to be mounted and to move laterally. The third linear push rod 81 is mounted on the frame 1, and the baffle 82 is located at the notch 84 and connected to the push rod end of the third linear push rod 81 to limit or release the first end shaft. The limiting bracket 85 is fixed on the frame 1, and a limiting hole is provided on the limiting bracket 85. The linkage 83 is disposed in the limiting hole, and a deflection gap is formed between the linkage 83 and the limiting hole. The linkage 83 is connected to the second end shaft of the roll material rotating roller 71 so that the roll material rotating roller 71 swings around the linkage 83. With this structure and gear synchronous transmission, the second driving gear 72 and the second driven gear 73 can be separated without shutting down the equipment, thereby swinging the roll material rotating roller 71. The linkage 83 can deflect within the limiting hole. A small swing of the second end shaft allows the first end shaft to swing significantly around the linkage 83 and move laterally out of the frame along the notch 84. Once the first end shaft is installed in place within the notch 84, the third linear push rod 81 pushes the baffle 82 to the side where the first end shaft has moved out, thus fixing the baffle 82 at the notch 84 to ensure the stability of the entire coating equipment. In practical applications, after the first end shaft of the unwinding mechanism 2's roll material rotating roller 71 moves laterally out of the frame, the roll material to be coated can be loaded onto the unwinding mechanism 2's roll material rotating roller 71; and after the first end shaft of the winding mechanism 3's roll material rotating roller 71 moves laterally out of the frame, the coated roll material can be unloaded from the unwinding mechanism 2's roll material rotating roller 71.

[0056] Preferably, the third drive motor 74 on the take-up rotary roller is a servo drive motor, and a magnetic powder tension controller is installed on the unwinding rotary roller. The magnetic powder tension controller uses a conventional magnetic powder tension controller found on existing coating equipment, primarily used to continuously control the tension of the rolled material during transport on the unwinding rotary roller. Its working principle is as follows: When the magnetic powder material passes through the conveying path, a tension sensor measures the tension of the magnetic powder material and feeds the measurement result back to the control center. Based on the measurement result, the control center adjusts the current or magnetic field of the electromagnet or magnet to change the magnitude of the magnetic force, thereby adjusting the tension of the magnetic powder material. Through continuous feedback and adjustment, the magnetic powder tension controller can achieve precise control of the magnetic powder material tension. Furthermore, preferably, the rotation speed of the unwinding rotary roller and the collecting rotary roller can be controlled in real time based on a PLC torque mode algorithm, ensuring that the linear speeds of the take-up shaft, the feeding shaft, and the unwinding shaft are always consistent, maintaining the rolled material tension in a constant state, and ensuring uniform oil coating.

[0057] Furthermore, combined Figure 2 and Figure 10 As shown, the oil coating equipment also includes a traction mechanism 9. The traction mechanism 9 includes a track 91, a material head fixing rod 92, a transmission rod 93, and a fourth drive motor. Tracks 91 are fixed on both sides of the frame 1, and the tracks 91 are laid out along the conveying path of the roll material to be coated. Specifically, the tracks 91 are laid out along the path of the unwinding mechanism 2, the coating mechanism 4, the oil coating and curing mechanism 5, the edge trimming mechanism 6, and the winding mechanism 3, with one end of the track 91 located above the inner side of the unwinding mechanism 2 and the other end located below the inner side of the winding mechanism 3. A chain is installed inside the track 91; the chain is a single chain. The material head fixing rod 92 is located between the two tracks 91, and its end is connected to the chain, allowing it to move along the track 91. The material head fixing rod 92 is mainly used to fix the pulled-out end of the roll material to be coated by adhesive or clamping. The transmission rod 93 is located at the bottom of the frame 1 and is positioned between the two tracks 91. Drive gears 94 are connected to both ends of the transmission rod 93, and the drive gears 94 mesh with the chain. The fourth drive motor is fixed to the frame 1, and the output end of the fourth drive motor is connected to the transmission rod 93. With this structure, the fourth drive motor drives the transmission rod 93 to rotate. Based on the meshing of the drive gears 94 and the chain, the chain drives the material head fixing rod 92 to move along the track 91. Thus, when the equipment is running, the material head fixing rod 92 pulls the roll material to be coated onto the unwinding mechanism 2, and then through the coating mechanism 4, the oil curing mechanism 5, and the edge trimming mechanism 6 to the winding mechanism 3. No manual feeding operation is required, which improves production efficiency and avoids safety accidents caused by operators coming into contact with the running equipment.

[0058] Preferably, a collection box can be installed below the bottom of the track 91 to collect the chain that has slid off the track 91. After the roll material to be coated is conveyed to the winding mechanism 3, the material head fixing rod 92 and the coated roll can be manually separated, and the fourth drive motor can be controlled to drive the transmission rod 93 to rotate in the opposite direction, so that the material head fixing rod 92 returns to its initial position. Since the oil coating gap and the position of the blade holder 62 are both adjustable, the movement of the transmission rod 93 will not affect the operation of the various mechanisms.

Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of the present invention.
