Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0041] Please also refer to Figures 1 to 5 The UV adhesive laminating machine provided in the embodiment of the present application is now described. The UV adhesive laminating machine includes a wall panel 100, a water-cooled roller 101, a pressing adhesive roller 102, a first cylinder 103, a feeding assembly, a glue coating assembly, and a UV light curing device 110. Among them:

[0042] The water-cooled roller 101 is rotatably mounted on the wall panel 100 and is used for water cooling; the pressing rubber roller 102 is parallel to the water-cooled roller 101; the output end of the first cylinder 103 is connected to the pressing rubber roller 102 and is used to drive the pressing rubber roller 102 to move closer to or away from the water-cooled roller 101; the feeding assembly includes a film unwinder 104 for unwinding the target film material 201 and enabling the target film material 201 to pass through the gap between the water-cooled roller 101 and the pressing rubber roller 102 in a flat posture, and also includes a paper feeder 105 for supplying the target printed product 202 and enabling the target printed product 202 to pass through the gap between the water-cooled roller 101 and the pressing rubber roller 102; the gluing assembly includes an anilox roller 106, a rotary roller 107, and a roller 108 respectively rotatably mounted on the wall panel 100 and parallel to each other. The transfer roller 107 and steel roller 108 also include a rubber disc 109 with an open top for accommodating UV adhesive. The anilox roller 106 is positioned horizontally on top of the rubber disc 109 and at least partially extends into the interior of the rubber disc 109 to extract adhesive from the rubber disc 109. A passage for the target film 201 to pass between the film supply unwinder 104 and the laminating rubber roller 102 is formed between the transfer roller 107 and the steel roller 108. The anilox roller 106, transfer roller 107, and steel roller 108 are also configured to move closer or further away from each other to apply adhesive extracted from the rubber disc 109 by the anilox roller 106 to the target film 201. A UV curing device 110 is mounted on the wallboard 100 and is configured to cure the UV adhesive bonded between the target film 201 and the target printed product 202. For ease of illustration, this embodiment uses paper as the target printed product 202 as an example. In addition, the UV glue described in this embodiment is also known as shadowless glue, photosensitive glue, and ultraviolet light curing glue in the art. It is a type of adhesive that must be cured by ultraviolet light irradiation, and will not be described in detail here.

[0043] According to the above structure provided in this embodiment, in the UV glue laminating machine provided in this embodiment, the water-cooled roller 101 and the pressing rubber roller 102 that can be close to the water-cooled roller 101 form a working gap for pressing the target film material 201 onto the target printed product 202. After the anilox roller 106 takes the UV glue from the material tray, it can transfer the UV glue to the transfer roller 107 by contacting with the transfer roller 107. Since the target film material 201 between the film unwinder 104 and the pressing rubber roller 102 also needs to pass through the gap between the transfer roller 107 and the steel roller 108, when the transfer roller 107 is close to the steel roller 108, UV glue can be applied to the target film material 201. In this way, the target film material 201 coated with UV glue can be preliminarily bonded to the target printed product 202 through the cooperation of the pressing rubber roller 102 and the water-cooled roller 101 and installed on the wall panel. The ultraviolet light curing device 110 on 100 can quickly cure the UV glue by irradiating the UV glue, so that the target film material 201 can quickly form a stable bond with the target printed product 202. Therefore, the UV glue laminating machine provided in this embodiment can provide higher laminating efficiency, and the printed product after laminating through the above technical solution reaches more than 170GU through the gloss tester test, which is much higher than the gloss of 100-110GU of the printed product after laminating by the traditional dry laminating method, wet laminating method and pre-coating film method. Therefore, this technical solution is far superior to the existing technology.

[0044] It should be noted that the UV curing device 110 described in this embodiment can adopt a structure such as an LED UV lamp commonly used in the art. In order to achieve a better curing effect, the UV curing device 110 can also be provided with at least one set on the front and back of the composite material, which will not be described in detail here.

[0045] In another embodiment of this application, please refer to Figures 1 to 5 The gluing assembly also includes a second cylinder 111 installed on the wall panel 100, a C-shaped arm 112 one end of which is connected to the output end of the second cylinder 111, and a first sliding seat 113 slidably connected to the wall panel 100; the second cylinder 111 and the first sliding seat 113 are arranged on opposite sides of the steel roller 108, and the end of the C-shaped arm 112 away from the second cylinder 111 bypasses the steel roller 108 and is connected to the first sliding seat 113, and the transfer roller 107 is rotatably installed on the first sliding seat 113.

[0046] According to the above structure provided in this embodiment, by providing a C-shaped arm 112 that bypasses the steel roller 108, the second cylinder 111 and the first sliding seat 113 are arranged on opposite sides of the steel roller 108, which can significantly reduce the overall space occupied by the UV glue laminating machine in this embodiment. In addition, the curved structure of the C-shaped arm 112 can make the C-shaped arm 112 itself have a certain degree of elasticity. In this way, when the second cylinder 111 drives the transfer roller 107 to approach the steel roller 108, the C-shaped arm 112 can offset a portion of the pressure between the transfer roller 107 and the steel roller 108. This makes the transfer roller 107 and the steel roller less susceptible to damage and facilitates the stable use of the UV glue laminating machine in this embodiment for a longer period of time.

[0047] In another embodiment of this application, please refer to Figures 1 to 5 Two sets of second cylinders 111, C-shaped arms 112, and first sliding seats 113 are provided, and the two first sliding seats 113 are connected to both ends of the transfer roller 107. According to the above structure provided in this embodiment, by providing two sets of second cylinders 111, C-shaped arms 112, and first sliding seats 113, the transfer roller 107 can more stably maintain a parallel posture with the steel roller 108 when approaching the steel roller 108. This is conducive to significantly improving the uniformity of the UV adhesive coating on the target film material 201 and achieving a better laminating effect of the UV adhesive laminating machine in this embodiment.

[0048] In another embodiment of this application, please refer to Figures 1 to 5 The gluing assembly also includes a pin 114 connected to the C-shaped arm 112, a rotating shaft 115 rotatably mounted on the wall panel 100, and a swing arm 116 with one end fixed to the rotating shaft 115; the pin 114 and the rotating shaft 115 are both parallel to the transfer roller 107, and the end of the swing arm 116 away from the rotating shaft 115 forms a fork 117 for accommodating the pin 114, and the fork 117 faces away from the rotating shaft 115.

[0049] According to the above structure provided in this embodiment, when the outputs of the two groups of second cylinders 111 are not synchronized, the swing arms 116 connected to the same rotating shaft 115 can influence and restrict each other, that is, through the fork 117 connected to the pin 114 on the C-shaped arm 112 and the rotating shaft 115, the C-shaped arms 112 at both ends maintain synchronous movement and thus synchronize the movement of the two first sliding seats 113, so that the two ends of the transfer roller 107 can maintain more stable synchronous movement. At the same time, this synchronization technology effectively avoids the jamming or even jamming of the first sliding seats 113 at both ends of the transfer roller 107 with the corresponding guide components on the wall panel 100 when the movement is not synchronized, thereby ensuring the smoothness of the transfer roller 107 when it moves relative to the steel roller 108, which is conducive to further improving the laminating effect of the UV glue laminating machine in this embodiment.

[0050] In another embodiment of this application, please refer to Figures 1 to 5 The glue coating assembly also includes a first limit seat 118 connected to the wall panel 100, a first limit rod 119 that moves through the first limit seat 118, and a first nut 120 that is threadedly connected to the first limit rod 119; the first limit rod 119 is connected to the first sliding seat 113 and the moving direction of the first limit rod 119 relative to the first limit seat 118 is parallel to the sliding direction of the first sliding seat 113, and the first nut 120 and the first sliding seat 113 are located on opposite sides of the first limit seat 118.

[0051] According to the above structure provided in this embodiment, when the first sliding seat 113 drives the first moving rod to move relative to the first limiting seat 118, the first nuts 120 threadedly connected to the first limiting rod 119 and arranged on opposite sides of the first limiting seat 118 with the first sliding seat 113 can serve as a limiting structure for the first limiting rod 119, thereby limiting the range of motion of the first limiting rod 119. This helps prevent the first sliding seat 113 from excessively moving under the drive of the second cylinder 111 and damaging the transfer roller 107 or the steel roller 108, thereby ensuring that the UV glue laminating machine in this embodiment can be used stably for a longer period of time. In this embodiment, in order to achieve a better limiting effect, at least two first nuts 120 can be threadedly connected to the first limiting rod 119.

[0052] In another embodiment of this application, please refer to Figures 1 to 5 The gluing assembly also includes a third cylinder 121 installed on the wall panel 100, a second sliding seat 122 slidably connected to the wall panel 100, and a scraper 123 abutting against the anilox roller 106; the output end of the third cylinder 121 is connected to the second sliding seat 122 and is used to drive the second sliding seat 122 to slide relative to the wall panel 100, the anilox roller 106 is rotatably installed on the second sliding seat 122, and the sliding direction of the second sliding seat 122 is perpendicular to the sliding direction of the first sliding seat 113.

[0053] According to the structure provided in this embodiment, the third cylinder 121 can be slidably connected to the second sliding seat 122 on the wall panel 100 to stably drive the anilox roller 106 toward or away from the transfer roller 107. Furthermore, because the sliding direction of the second sliding seat 122 is perpendicular to the sliding direction of the first sliding seat 113, the overall volume of the UV adhesive laminating machine in this embodiment can be significantly reduced. Furthermore, the scraper 123 abutting against the anilox roller 106 can ensure that the adhesive material applied by the anilox roller 106 from the adhesive disc 109 is more evenly distributed, further improving the laminating effect of the UV adhesive laminating machine in this embodiment.

[0054] In another embodiment of this application, please refer to Figures 1 to 5The glue coating assembly also includes a second limit seat 124 connected to the wall panel 100, a second limit rod 125 that movably passes through the second limit seat 124, and a second nut 126 that is threadedly connected to the second limit rod 125; the second limit rod 125 is connected to the second sliding seat 122 and the moving direction of the second limit rod 125 relative to the second limit seat 124 is parallel to the sliding direction of the second sliding seat 122, and the second nut 126 and the second sliding seat 122 are located on opposite sides of the second limit seat 124.

[0055] According to the above structure provided in this embodiment, when the second sliding seat 122 drives the second movable rod to move relative to the second limiting seat 124, the second nuts 126 threadedly connected to the second limiting rod 125 and arranged on opposite sides of the second limiting seat 124 with the second sliding seat 122 can serve as a limiting structure for the second limiting rod 125, thereby limiting the range of motion of the second limiting rod 125. This helps prevent the second sliding seat 122 from excessively moving under the drive of the third cylinder 121 and damaging the transfer roller 107 or the anilox roller 106, thereby ensuring that the UV adhesive laminating machine in this embodiment can be used stably for a longer period of time. In this embodiment, to achieve a better limiting effect, at least two second nuts 126 can be threadedly connected to the second limiting rod 125.

[0056] In another embodiment of this application, please refer to Figures 1 to 5 The glue coating assembly also includes a fourth cylinder 127 installed on the wall panel 100 and a support block 128 connected to the output end of the fourth cylinder 127; the output direction of the fourth cylinder 127 is parallel to the opening direction of the glue disc 109, and the side of the support block 128 facing away from the fourth cylinder 127 forms a step 129, a groove 130 and a support surface 131 adjacent to each other in sequence. The glue disc 109 abuts against the support surface 131 and forms a protrusion 132 that is respectively engaged with the inner corner of the step 129 and the groove 130.

[0057] According to the above structure provided in this embodiment, the rubber disc 109 can be detachably connected to the support block 128 by engaging the protrusion 132 at the inner corner of the step 129 and in the engaging groove 130. In this way, when the support block 128 retracts under the drive of the fourth cylinder 127, the rubber disc 109 can gradually move away from the anilox roller 106. Therefore, the rubber disc 109 provided in this embodiment can also achieve the technical effect of convenient disassembly and cleaning. In addition, the protrusion 132 adopts an arc structure to engage with the step 129 and the slot 130. In this way, by arranging the structure of the step 129 and the slot 130 on the support block 128, the operator only needs to press the rubber disc 109 slightly downward on the side close to the step 129. At this time, the rubber disc 109 will flip with the outer circular surface of a protrusion 132 located on the step 129 as the rotating mating surface, so that the protrusion 132 in the slot 130 can be lifted and separated from the slot, and then the rubber disc 109 can be easily removed from the support block 128, which has a more flexible and convenient disassembly and assembly effect; at the same time, during installation, one of the protrusions 132 is engaged with the slot 130 to achieve instant engagement and positioning with good positioning stability.

[0058] In another embodiment of this application, please refer to Figures 1 to 5 The feeding assembly also includes a cam 133 rotatably mounted on the wall panel 100, a follower arm 134 hinged on the wall panel 100 and adapted to the working surface of the cam 133, a follower rod 135 hinged to the follower arm 134, and a baffle 136 connected to the end of the follower rod 135 away from the follower arm 134; the baffle 136 is used to be driven by the cam 133 to move back and forth, and the moving path of the baffle 136 interferes perpendicularly with the conveying path of the target printed product 202. Here, it can be understood that the baffle 136 is usually installed on a guide member, and the guide member can adopt the linear rail and slide groove structure of the existing technology.

[0059] According to the above structure provided in this embodiment, the baffle 136 driven by the cam 133 can reciprocate perpendicular to the direction of the conveying path of the target printed product 202. When the baffle 136 is higher than the conveying path of the target printed product 202, the target printed product 202 is blocked. When the baffle 136 retracts, the target printed product 202 can continue to be conveyed forward by the paper feeding component of the laminating machine to the water-cooled roller 101. This not only allows the target printed product 202 to reach the pressing rubber wheel in a more orderly posture after abutting with the baffle 136, but also allows a preset distance to be formed between the target printed products 202, which is conducive to better adapting to the gluing process and achieving a better laminating effect of the UV glue laminating machine in this embodiment. Here, the paper feeding component can adopt the existing technology of the laminating machine.

[0060] In another embodiment of this application, please refer to Figures 1 to 5The feeding assembly also includes a corona device 137 mounted on the wall panel 100 and used to change the surface tension of the target structure. Two sets of corona devices 137 are provided, corresponding to the film unwinder 104 and the paper feeder 105. The target film material 201 between the film unwinder 104 and the laminating roller 102, as well as the target printed product 202 between the paper feeder 105 and the laminating roller 102, both pass through the corresponding corona devices 137. According to the above structure provided in this embodiment, the two sets of corona devices 137, corresponding to the film unwinder 104 and the paper feeder 105, can significantly improve the surface adhesion of the target film material 201 and the target printed product 202 by surface treatment, changing the surface tension of both. This allows the UV glue to be more tightly bonded between the target film material 201 and the target printed product 202, thereby achieving a better laminating effect of the UV glue laminating machine in this embodiment.

[0061] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
