Description

Technical Field

[0001] The utility model relates to the technical field of pre-coating equipment, in particular to a glue coating device for producing pre-coating films with uniform glue coating. Background Art

[0002] Pre-coating refers to the process of pre-gluing and rewinding plastic film before laminating it with paper printed products. The pre-coating factory first applies glue on the film according to the specifications and format of use, rewinds it for the user to choose, and then laminates it with the printed product. Lamination, also known as film pasting, is a processing technology that coats plastic film with adhesive and bonds it to paper printed products through heating and pressurization to form a paper-plastic integrated product. The laminated printed product has a smoother and brighter surface due to the extra layer of thin and transparent plastic film, thereby improving the gloss and fastness of the printed product, making the graphics more colorful and three-dimensional. At the same time, it also plays the role of waterproof, anti-fouling, wear-resistant, fold-resistant, and chemical-resistant.

[0003] After searching, a Chinese patent with publication number CN213792489U discloses a glue coating device for protective film production. The patent describes a technical solution in which a rotating plate and a sliding frame are provided so that when the rotating plate rotates, the sliding frame is driven to rotate as well. The rotation trajectory is like a palm smearing, which can evenly spread the colloid on the protective film, so that the colloid can more completely cover the protective film, making the surface of the protective film smooth, enhancing the feel, and improving the quality of the protective film.

[0004] In this solution, although the protective film is like a palm when applying glue, the glue output is different during the gluing process, resulting in different glue thicknesses on each part of the protective film, which is inconvenient for users to use and greatly reduces the quality of the protective film. In order to solve this technical problem, the utility model proposes a gluing device for pre-coated film production with uniform glue application. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] See also Figure 1-4 , the utility model provides a technical solution:

[0025] Embodiment 1: A glue coating device for producing pre-coated films with uniform glue coating, comprising a base 1, fixedly connected to the top of both ends of the base 1 with a fixed frame 3, a pair of rotating rollers 4 being rotatably connected inside the fixed frame 3, a film body 5 being arranged between the rotating rollers 4 on both sides, a shell 2 being fixedly connected to the top in the middle of the base 1, a glue storage box 15 being arranged outside the shell 2, a connecting pipe 17 being fixedly connected to the bottom of the glue storage box 15, a control valve 16 being fixedly connected to the outer wall of the connecting pipe 17, and a nozzle 18 being fixedly connected to the bottom end of the connecting pipe 17, an inner plate 24 being fixedly connected to the inside of the shell 2, an electric push rod 23 being fixedly connected to the bottom of the inner plate 24, an output end of the electric push rod 23 being fixedly connected to a connecting frame 25, and a roller 26 being rotatably connected to the inside of the connecting frame 25, and a limiting block 27 being fixedly connected to the top of the connecting frame 25, the limiting block 27 being slidably connected to the inner plate 24, and a pressure roller 22 being rotatably connected to the inside of the shell 2.

[0026] The membrane body 5 is guided by the rotating roller 4 on the fixed frame 3 and the outer shell 2, and passes through the entire device from one end to the other. After the control valve 16 is opened, the glue flows from the connecting pipe 17 to the nozzle 18, and is then applied to the surface of the membrane body 5 by the nozzle 18. When the membrane body 5 passes the bottom of the outer shell 2, the pressure roller 22 ensures that the glue is evenly flattened. At the same time, the electric push rod 23 is started to move the connecting frame 25 left and right. The connecting frame 25 limits the movement range through the limit block 27 on the inner plate 24. The movement of the connecting frame 25 drives the roller 26 to push back and forth on the surface of the membrane body 5 to ensure that the glue is evenly applied, thereby improving the quality and consistency of the membrane body 5.

[0027] Example 2: The difference between this example and Example 1 is that, the outer wall of the shell 2 is fixedly connected to the motor 1 6, the output end of the motor 1 6 is fixedly connected to the threaded rod 7, and the outer wall of the threaded rod 7 is threadedly connected to the connecting block 28, and the outer wall of the connecting block 28 is fixedly connected to the bracket 8, and the bracket 8 is slidably connected to the fixed block 13, the glue storage box 15 is fixedly connected to the outer wall of the fixed block 13, and the other side of the fixed block 13 is fixedly connected to the rack 14, and the outer wall of the bracket 8 is fixedly connected to the mounting plate 9, and the top of the mounting plate 9 is fixedly connected to the motor 2 10, the output end of the motor 2 10 is fixedly connected to the rotating shaft 11, and the outer wall of the rotating shaft 11 is fixedly connected to the gear 12, and the gear 12 is meshed with the rack 14, the rear end of the shell 2 is fixedly connected to the inside of the fixed frame 19, the inside of the fixed frame 19 is fixedly connected to the fan 21, the inside of the fixed frame 19 is fixedly connected to the dustproof net 20, the dustproof net 20 is located above the fan 21, and the fan 21 corresponds to the membrane body 5.

[0028] By starting the motor 1 6 on the outer shell 2, the threaded rod 7 rotates accordingly, driving the connecting block 28 and the bracket 8 to move left and right, thereby adjusting the position of the glue storage box 15 on the fixed block 13 in the bracket 8. At the same time, start the motor 2 10 on the top of the mounting plate 9, which drives the rotating shaft 11 and the gear 12, causing the rack 14 to move up and down, thereby adjusting the angle of the fixed block 13, and realizing precise adjustment of the glue storage box 15 during the coating process. After the coating is completed, by starting the fan 21 inside the fixed frame 19 and using the dustproof net 20 to prevent dust from entering, the glue is quickly blown dry to ensure product quality and production efficiency.

[0029] Working principle: first, the membrane body 5 passes through a pair of rotating rollers 4 on the right side fixing frame 3 and extends through the shell 2 to the rotating roller 4 on the other side. At this time, by starting the motor 16 outside the shell 2, the threaded rod 7 is driven to rotate under the action of the motor 16. The rotation of the threaded rod 7 will drive the connecting block 28 to move left and right, and the movement of the connecting block 28 will drive the bracket 8 to move left and right, so that the glue storage box 15 on the fixed block 13 inside the bracket 8 can be adjusted left and right. At this time, start the motor 2 10 on the top of the mounting plate 9. Under the action of the motor 2 10, the rotating shaft 11 is driven to rotate and the transmission gear 12 is rotated. When the gear 12 rotates, it will drive the rack 14 to move up and down, thereby driving the fixed block 13 to move. Through the cooperation between them, the glue storage box 15 can be adjusted at multiple angles, making it more accurate when applying. At this time, open the control valve 16 and the glue The water flows to the nozzle 18 through the connecting pipe 17, and then flows to the membrane body 5 through the nozzle 18. When the membrane body 5 passes the bottom of the shell 2, the thicker glue is flattened by the pressure roller 22. At this time, the electric push rod 23 is started, and the connecting frame 25 is pushed to move left and right under the action of the electric push rod 23. At the same time, the connecting frame 25 is limited on the inner plate 24 by the limit block 27 when moving. The movement of the connecting frame 25 will drive the roller 26 to push back and forth on the membrane body 5, so that the glue on the membrane body 5 is evenly spread, thereby ensuring the better quality of the membrane body 5. Through the cooperation between them, the effect of evenly spreading the glue on the membrane body 5 is achieved, and the product quality is improved. After the spreading is completed, the fan 21 inside the fixed frame 19 is started, and the glue is blown dry under the action of the fan 21. At the same time, the fan 21 is dust-proof through the dustproof net 20 when in use.
