Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging paper production technology, specifically to a coating and laminating equipment for producing packaging paper bags. Background Technology
[0002] Coating and laminating packaging paper has multiple functions. First, it improves the barrier properties of the packaging paper, blocking moisture and oxygen, protecting the contents from dampness and spoilage. Second, it enhances the strength and toughness of the packaging paper, making it more resistant to wear and tear, and extending its service life. Third, it improves the surface properties of the packaging paper, giving it better printability and gloss, enhancing the packaging's aesthetics and product appeal. Furthermore, it can endow the packaging paper with special properties such as antibacterial and antistatic properties, meeting the packaging needs of different products.
[0003] The existing Chinese utility model patent with publication number CN217699785U discloses a coating and laminating equipment for producing paper bags. This equipment includes a fixed frame, a movable frame, hollow plates, and an electric push rod. Three sets of hollow plates are fixedly connected to both the fixed and movable frames. The upper set of hollow plates has a through hole at its bottom, the middle set has through holes at both the top and bottom, and the lower set has a through hole at its top. Connecting pipes are fixedly connected to the sides of the fixed and movable frames, with one end of each pipe passing through the frame and communicating with the interior of the hollow plates. The beneficial effect is that, by using an electric push rod in conjunction with a third rotating shaft and a third bearing, the movable frame can be moved around a pivot point via the extension and retraction of the electric push rod. This allows the tilting of the movable frame to tighten the packaging film, preventing wrinkles during film transport, reducing the need for subsequent film trimming, and minimizing manual labor input.
[0004] Currently, the coating and laminating equipment used in the production of packaging paper bags still has the following problems:
[0005] When packaging paper is coated, if the viscosity of the coating is too high or too low, it will lead to uneven coating, which will affect the packaging performance and printing quality. In addition, if the tension is not well controlled during the coating process, the paper will shake during the coating process, resulting in streaks or bubbles on the coating surface, which will also affect the uniformity of the coating. Utility Model Content
[0006] The purpose of this invention is to provide a coating and laminating equipment for the production of packaging paper bags, so as to solve the problems mentioned in the background art.
[0007] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:
[0008] This utility model provides a coating and laminating equipment for producing packaging paper bags, including a coating frame, a take-up roller, and a scraper plate device. The take-up roller is installed on the middle side of the coating frame, and a scraper plate device is installed on the opposite side of the take-up roller. Both sides of the take-up roller are connected to a roller shaft, and the roller shaft passes through the inside of the roller frame ring. The roller frame ring is fixedly installed on the upper side of one side of the left support plate. An adjustment frame is obliquely connected to the bottom of the left support plate, and a lifting rod is movably installed on one side of the adjustment frame.
[0009] The bottom of the cylindrical fixing pin is inserted above the midpoint of the scraper plate device, and the fixing pin is located at the midpoint of the connecting frame. Both ends of the connecting frame are fixedly connected to the connecting ring. One side of the connecting ring is directly connected to the slider, and a lead screw is inserted inside the slider.
[0010] Preferably, the bottom of the adjustment frame is provided with a base block, and the lifting rod is connected between the left support plate and the base block. A handle is fixedly installed on one side of the left support plate, and one side of the left support plate is movably connected to the side of the coating machine frame.
[0011] Preferably, a fixed rod is connected between the sliders, and the fixed rod is located at the upper apex of the slider.
[0012] Preferably, the coating frame has two sets of processing rollers in the middle, and the take-up roller and the scraper plate device are horizontally located on the middle side of the two sets of processing rollers. The bottom of the coating frame is fixedly installed with an operating table, and the scraper plate device is fixedly equipped with right support plates on both sides.
[0013] Preferably, the right support plate includes a card plate fixedly connected at one end, and a side plate groove is provided on one side of the right support plate, and the slider is located inside the side plate groove. A motor box is connected to the opposite side of the card plate.
[0014] Preferably, a clamping plate is fixedly installed on one side of the left support plate, and the clamping plate is located in the grooves on both sides of the coating machine frame, and the left support plate and the right support plate are located on the same horizontal line.
[0015] Preferably, the processing roller includes a rotating shaft rotatably connected on both sides, and one side of the rotating shaft is rotatably connected to a servo motor. A gear is connected to one side of the servo motor shaft, and the two sets of gears are meshed together.
[0016] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:
[0017] 1. When packaging paper is being coated and laminated, the scraper plate device moves horizontally on the surface of the packaging paper through the connecting frame and slider, which can evenly coat the coating inside the composite packaging paper, reduce the influence of coating viscosity on the packaging paper, ensure consistent coating thickness, improve the barrier and waterproof properties of the packaging paper, and effectively eliminate problems such as unevenness, bubbles and wrinkles on the coating surface, making the surface of the packaging paper smoother and flatter, and improving the aesthetics of the packaging paper.
[0018] 2. When the packaging paper is being coated and laminated, the scraper plate device and the left and right support plates are connected below the scraper plate device respectively. The height of the left and right support plates is adjusted by the adjusting frame and the lifting rod to control the tension of the packaging paper inside the processing roller. Packaging paper with appropriate tension helps the scraper plate device to apply the coating evenly. At the same time, it can also make the packaging paper fit tightly during winding and lamination, resulting in a neat and beautiful appearance and enhancing market competitiveness.
