Description

Technical Field

[0001] The utility model relates to the technical field of pre-coated film gluing, in particular to a uniform gluing mechanism for pre-coated film processing. Background Technique

[0002] A pre-coated film refers to a printed matter obtained by pre-coating a plastic film with glue, rewinding it, and then laminating it with a paper print. Since there is a thin and transparent plastic film on the surface, the surface is smooth and bright, thus improving the gloss and fastness of the printed matter, making the colors more vivid, three-dimensional, and also playing roles such as waterproofing, abrasion resistance, and chemical corrosion resistance.

[0003] After retrieval, the existing patent (Publication No.: CN 211463597 U) discloses a gluing device for pre-coated film processing, which solves the problem that the general pre-coated film gluing device relies on a gluing roller to apply glue and then coat, resulting in uneven coating. It includes a support platform and a conveyor belt installed on the upper surface of the support platform. Support blocks are arranged on both sides of the conveyor belt. A first mounting frame is fixed between the tops of the two support blocks. A gluing roller is rotatably installed inside the first mounting frame. One end of the gluing roller penetrates the first mounting frame, and a first pulley is concentrically fixed to the outer end of the gluing roller. And a pipeline is arranged on one side of the gluing roller. The pipeline is fixed on the first mounting frame, and several nozzles are arranged on the bottom surface of the pipeline. In this device, glue is pre-sprayed on the pre-coated film through the nozzles, and then the gluing roller is driven by a motor to apply glue to the pre-coated film, so that the glue is more evenly applied to the surface of the pre-coated film, improving the gluing effect.

[0004] However, in the above solution, the gluing device transports glue through nozzles. During use, the nozzles can only be started or closed together, and there is no way to adjust the spraying range of the glue according to the width of the film, resulting in a relatively limited application range of the device.

[0005] In view of this, the utility model proposes a uniform gluing mechanism for pre-coated film processing. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts fall within the scope of protection of the present utility model.

[0026] Embodiment 1

[0027] The preferred embodiment of a uniform glue coating mechanism for pre-coated film processing provided by the present utility model is as follows Figures 1 to 5 shown: A uniform glue coating mechanism for pre-coated film processing includes a base 1. A workbench 2 is arranged on the top of the base 1. A glue storage barrel 3 is placed inside the workbench 2 on the top of the base 1. A servo motor 4 is rotatably connected to the back of the glue storage barrel 3. The output end of the servo motor 4 is fixedly connected to a stirring rod 5. A first connecting pipe 6 is fixedly connected to the side of the glue storage barrel 3. A drying and cooling equipment main body 7 is arranged on the side of the workbench 2 on the top of the base 1. A glue spraying mechanism 8 is fixedly connected to the side of the drying and cooling equipment main body 7. Two glue coating rollers 9 are rotatably connected to the surface of the workbench 2. Gears 10 are fixedly connected to the backs of the two glue coating rollers 9. A guide roller 11 is rotatably connected to the inner wall of the drying and cooling equipment main body 7.

[0028] In this embodiment, multiple groups of servo motors 4 are provided. The glue spraying mechanism 8 includes a glue pipe 81, a lead screw 82, a slider 83, a transmission rod 84, a control board 85 and a second connecting pipe 86. The glue pipe 81 is fixedly connected to the side of the drying and cooling equipment main body 7. The lead screw 82 is rotatably connected to the top of the glue pipe 81. The slider 83 is threadedly connected to the surface of the lead screw 82. The transmission rod 84 is fixedly connected to the surface of the slider 83. The control board 85 is fixedly connected to the bottom of the transmission rod 84. The second connecting pipe 86 is fixedly connected to the side of the glue pipe 81. By setting the servo motor 4, the parts of the equipment can be driven to rotate. By setting the glue spraying mechanism 8, the surface of the pre-coated film can be sprayed with glue, and then it is smeared by the glue coating roller 9.

[0029] In this embodiment, two groups of threads in opposite directions are arranged on the surface of the lead screw 82. The two sliders 83 are meshed with the two threaded surfaces of the lead screw 82 respectively. Because two groups of threads in opposite directions are arranged on the surface of the lead screw 82, and the two sliders 83 are respectively meshed with it, when the lead screw 82 rotates counterclockwise, it will drive the two sliders 83 to slide relatively and move away from each other.

[0030] In this embodiment, four groups of transmission rods 84 are provided, and two groups of control boards 85 are provided. The two control boards 85 are slidably connected to the glue pipe 81. Because the four transmission rods 84 are respectively fixedly connected to the two sliders 83, when the two sliders 83 slide, they will drive the four transmission rods 84 to move relatively. At this time, the two control boards 85 respectively fixedly connected to the four transmission rods 84 will slide relatively and move away from each other on the inner wall of the glue pipe 81, and the lower glue outlet will be exposed. When the two control boards 85 slide to be consistent with the width of the pre-coated film, the rotation of the lead screw 82 can be stopped, so as to achieve the purpose of adjusting the lower glue range according to the width of the pre-coated film, and further increase the use range of the spraying equipment.

[0031] In this embodiment, four groups of mounting holes are provided on the sides of both the second connecting pipe 86 and the first connecting pipe 6. The four groups of mounting holes on the sides of the second connecting pipe 86 and the first connecting pipe 6 are arranged across the middle. Since the mounting holes on the side of the first connecting pipe 6 and the mounting holes on the side of the second connecting pipe 86 are both arranged across the middle, it is possible to prevent glue from seeping out and flowing onto the surface of the fixing member during the glue conveying process, thereby preventing the fixing member from rusting.

[0032] Embodiment 2

[0033] On the basis of Embodiment 1, a preferred embodiment of the uniform glue coating mechanism for pre-coated film processing provided by the present utility model is as Figures 1 to 5 shown: A support plate 12 is fixedly connected to the surface of the drying and cooling equipment main body 7. An operation screen 13 is arranged on the surface of the support plate 12. A protective plate 14 is connected to the inner wall of the support plate 12. A fixing column 15 penetrates through the surface of the protective plate 14. On the top of the base 1, a first mounting plate 16 is fixedly connected to the other side of the workbench 2. A feeding roller 17 is rotatably connected to the surface of the first mounting plate 16. On the top of the base 1, a second mounting plate 18 is fixedly connected to the side of the drying and cooling equipment main body 7. A winding roller 19 is rotatably connected to the surface of the second mounting plate 18.

[0034] In this embodiment, a circular groove matching the fixing column 15 is provided on the surface of the support plate 12. The fixing column 15 is slidably connected to the protective plate 14. By sliding the fixing column 15 upward to move the protective plate 14, when the fixing column 15 slides to correspond to the circular groove on the surface of the support plate 12, the fixing column 15 can be inserted into the circular groove on the surface of the support plate 12, and thus the protective plate 14 can be fixed in the current position.

[0035] The working principle and usage process of the present utility model: First, place the glue storage barrel 3 under the workbench 2, and then use a connecting pipe and a fixing member to connect the first connecting pipe 6 and the second connecting pipe 86. Since the mounting holes on the side of the first connecting pipe 6 and the mounting holes on the side of the second connecting pipe 86 are both arranged across the middle, it is possible to prevent glue from seeping out and flowing onto the surface of the fixing member during the glue conveying process, thereby preventing the fixing member from rusting.

[0036] Subsequently, slide the protective plate 14 upward through the fixed column 15. When the fixed column 15 slides to correspond to the circular groove on the surface of the support plate 12, the fixed column 15 can be inserted into the circular groove on the surface of the support plate 12, and then the protective plate 14 can be fixed at the current position. Then, start the servo motor 4 through the operation screen 13 to drive the screw rod 82 to rotate. Since there are two sets of threads in opposite directions on the surface of the screw rod 82, and the two sets of sliders 83 are respectively engaged with it, when the screw rod 82 rotates counterclockwise, it will drive the two sets of sliders 83 to slide relatively and move away from each other. Since the four sets of transmission rods 84 are respectively fixedly connected to the two sets of sliders 83, when the two sets of sliders 83 slide, they will drive the four sets of transmission rods 84 to move relatively. At this time, the two control plates 85 respectively fixedly connected to the four sets of transmission rods 84 will slide relatively on the inner wall of the rubber tube 81 and move away from each other, and the lower glue outlet will be exposed. When the two control plates 85 slide to be consistent with the width of the pre-coated film, the rotation of the screw rod 82 can be stopped, so as to achieve the purpose of adjusting the lower glue range according to the width of the pre-coated film, and further increase the use range of the spraying equipment.

[0037] After the adjustment is completed, connect the pre-coated film on the surface of the feeding roller 17 to the winding roller 19. Then start all the servo motors 4, so that the two sets of gears 10 drive the two sets of glue coating rollers 9 to rotate and the winding roller 19 to rotate respectively. Since there is a stirring rod 5 inside the glue storage barrel 3, the servo motor 4 can be used to drive the stirring rod 5 to rotate to prevent the glue inside the glue storage barrel 3 from solidifying. After the glue coating roller 9 evenly coats the surface of the pre-coated film with glue, it can be dried and cooled by the drying and cooling equipment main body 7, and then wound by the winding roller 19.

[0038] The above is only the preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
