Description

Technical Field

[0001] This utility model belongs to the field of automatic laminating machine technology, specifically, it relates to a fully automatic laminating machine that avoids the generation of air bubbles. Background Technology

[0002] Laminating machines can be divided into in-situ laminating machines and pre-coated laminating machines. They are devices used to apply plastic film to the surface of products by hot pressing to improve the product's gloss, tear resistance and other properties.

[0003] Automatic laminating machines can automatically apply plastic film to the surface of products. During use, the parameters of the coating roller and pressure roller are first adjusted, and then the product to be processed is placed between the coating roller and pressure roller. After the product passes through the coating roller and pressure roller, the lamination is completed.

[0004] Chinese utility model patent CN221623031U discloses a fully automatic laminating machine that avoids bubble formation, including a laminating machine body; a first support frame is fixedly connected to one end of the laminating machine body; an electric push rod is fixedly connected to the first support frame; a scraper is fixedly connected to the output end of the electric push rod; pressure rollers are connected to both ends of the scraper through connecting rods, and the bottom of the pressure rollers is at the same horizontal plane as the bottom of the scraper; the height of the scraper is adjusted by the output end of the electric push rod so that the scraper can contact the upper surface of the product. When the product finishes laminating and continues to move, it will pass under the scraper, and the scraper will continuously squeeze and hang the product surface, scraping out the gas in the film, reducing the amount of residual gas in the film, thereby reducing the probability of bubbles in the film and reducing the impact of bubbles on the product lamination quality. At the same time, the pressure rollers also flatten the film, and then tightly adhere the film to the product again, thereby improving the flatness and firmness of the coating layer.

[0005] The aforementioned existing technology also has the following drawbacks: when the cutter cuts off the excess film on both sides of the product, if it is close to the workpiece, it will rub against the workpiece, which may not only damage the product surface but also reduce the service life of the cutter. If it is not close to the workpiece, the film that extends beyond the edge of the workpiece needs to be cut, making the process more complicated. Utility Model Content

[0006] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0007] To address the problem mentioned in the background art that when the cutting blade cuts off excess film on both sides of a product, if it is close to the workpiece, friction will occur, which may damage the product surface and reduce the service life of the cutting blade. If it is not close to the workpiece, the excess film at the edge of the workpiece needs to be cut, making the process more complicated, the present invention adopts the following technical solution.

[0008] A fully automatic laminating machine that avoids bubble formation includes a laminating machine base plate. First supports are detachably connected to the outer walls of both sides at the center of the base plate. A plastic film roll is rotatably connected between the two first supports. Second supports are detachably connected to both sides of one end of the base plate. A first electric telescopic rod is detachably connected to the upper end of the second supports. The telescopic end of the first electric telescopic rod passes through the second supports and is detachably connected to a connecting plate. A bubble scraper is detachably connected to the bottom of the connecting plate. A pressure roller is detachably connected to the bottom of the connecting plate away from the plastic film roll. A cutting assembly is installed on the upper side of the base plate. The cutting assembly cuts the film exceeding the product's dimensions. A bonding assembly is installed on the cutting assembly, which makes the cutting assembly adhere tightly to the outer wall of the product.

[0009] Preferably, a dust collection component is installed on the first bracket on both sides to clean the dust on the product surface.

[0010] Preferably, an installation shaft is inserted between the first brackets on both sides. One end of the installation shaft outputs a roll of plastic film and is rotatably connected to a rotating shaft. An assembly plate is fixedly connected to the outer wall of the roll of plastic film using fixing bolts. A pin passing through the rotating shaft is fixedly connected to the outer wall of the assembly plate.

[0011] Preferably, the cutting assembly includes a rotating handwheel, a sliding block, a cutting blade, and a bidirectional screw. A sliding groove is provided at the upper end of the base plate of the laminating machine near the upper end of the second bracket. The bidirectional screw is rotatably connected inside the sliding groove. One end of the bidirectional screw extends out of the base plate of the laminating machine and is detachably connected to the rotating handwheel. Sliding blocks are slidably connected to both sides inside the sliding groove. The two sliding blocks are threadedly connected to the bidirectional screw. The upper end of the sliding block is detachably connected to the cutting blade.

[0012] Preferably, the bonding component includes an inner groove and a rubber rotating roller. The inner groove is provided on the opposite side of the two cutting blades, and the rubber rotating roller is rotatably connected to the two sides inside the inner groove.

[0013] Preferably, the vacuuming assembly includes a vacuum plate, a second electric telescopic rod, a filter box, an air pump, and a filter element. Through slots are provided on the first supports on both sides. The top inner side of the through slots on both sides is detachably connected to the second electric telescopic rod. The telescopic ends of the second electric telescopic rods on both sides are detachably connected to the vacuum plate. Multiple vacuum holes are provided at the bottom of the vacuum plate. A filter box is detachably connected to one end of the vacuum plate. A filter element is inserted into the upper end of the filter box. The air inlet of the air pump is detachably connected to the outer wall of the filter box. The air inlet of the air pump communicates with the vacuum holes at the bottom of the vacuum plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. Through the set cutting and bonding components, the bidirectional screw is rotated by rotating the handwheel, which allows the two cutting blades on both sides to move in opposite directions at the same time. This allows the two cutting blades to adhere to the outer wall of the product, thereby cutting the film that exceeds the product. The rubber rotating roller can contact the outer wall of the product and rotate adaptively during the product movement. The rubber setting also provides a certain degree of flexibility, avoiding indentation on the outer wall of the workpiece.

[0016] 2. The suction pump in the dust collection component generates suction through the suction holes, which can adsorb dust on the product surface before lamination and filter it through the filter element. The plug-in filter element makes it easier to clean the dust on the filter element and replace the filter element. The second electric telescopic rods on both sides can bring the dust collection plate closer to the surface of the workpiece according to the height of the workpiece.

[0017] 3. By removing the fixing bolts and pulling out the pin, the mounting shaft can be extracted, making it possible to replace the first bracket and thus making the replacement of the first bracket more convenient. Attached Figure Description
