Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, specifically to a film peeling and laminating machine for product printing. Background Technology

[0002] A laminating printing machine is a device used to coat the surface of printed materials with a layer of transparent plastic film.

[0003] For example, announcement number CN213891798U, entitled "A Lamination Printing Machine," includes a device body, support legs, a fixed crossbar, a rotating roller, a printing press, a guiding device, and a lamination device. Support legs are welded to the four corners of the bottom surface of the device body. A fixed crossbar is welded to the bottom of the right side surface of the device body. A rotating roller is rotatably mounted on the inner right end of the fixed crossbar via a bearing. A printing press is welded to the top of the right side surface of the device body, and a guiding device is welded to the right side surface of the printing press. When paper jams between the first and second rotating rods, grasping the handle and pulling it to the right causes the handle to move the bearing to the right. The buffer spring is stretched, causing the second rotating rod to move to the right, thus creating a gap between the first and second rotating rods. This facilitates the removal of paper jammed between the first and second rotating rods and enables maintenance.

[0004] The existing lamination and printing equipment mentioned above does not have a film-removing function, which makes it impossible for the equipment to print on some items with film on the surface. In addition, the lamination position cannot be adjusted according to the size of the item, which can easily affect the quality of the laminated and printed products. Therefore, it does not meet the current needs, and a film-removing and lamination machine for product printing is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a film-peeling and laminating machine for product printing, in order to solve the problem mentioned in the background art that the existing laminating printing device does not have a film-peeling function, which makes it impossible for the device to print on some items with film on the surface, and the laminating point cannot be adjusted according to the size of the item, which easily affects the quality of the laminated printed product.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a film-peeling and laminating machine for product printing, comprising: a conveying device, wherein a film-peeling assembly is installed at the feed end of the conveying device, a printing machine is installed at the rear end of the film-peeling assembly, a laminating assembly is installed at the rear end of the printing machine, and an adjusting assembly for adjusting the position of the laminating pressure roller is installed on the inner wall of the laminating assembly.

[0007] Preferably, the film-tearing assembly includes a feeding pressure roller, a first hot air blower is installed above the side of the feeding pressure roller, a film-tearing take-up roller is installed above the side of the first hot air blower, a first motor is installed at one end of the film-tearing take-up roller to drive its rotation, and a film-tearing guide roller is installed below the side of the film-tearing take-up roller.

[0008] Preferably, the coating assembly includes a first coating roller and a second coating roller located at the bottom of both ends, and the adjustment assembly includes a plurality of sliding grooves symmetrically formed on the inner wall of the coating assembly. A guide rod is installed inside the sliding groove, and a sliding table is installed on the outer wall of the guide rod. The ends of the first coating roller and the second coating roller are both installed on the sliding tables on both sides.

[0009] Preferably, the slide grooves are provided with vertically spaced positioning holes, and bolts are installed in the openings on the outer wall of the slide table, with one end of the bolts extending into the positioning holes.

[0010] Preferably, a film-coating guide roller is installed above the first film-coating pressure roller, a second hot air blower is installed between the film-coating guide roller and the first film-coating pressure roller, an unwinding roller is installed above the side of the film-coating guide roller, a film-coating take-up roller is installed above the side of the second film-coating pressure roller, a second motor is installed at one end of the film-coating take-up roller to drive its rotation, and the unwinding roller and the film-coating take-up roller are connected by a film body.

[0011] Preferably, an adhesive surface is provided at the middle position of the membrane, and side strips are provided on both sides of the membrane.

[0012] Preferably, a cutting assembly is installed between the first coating roller and the second coating roller. The cutting assembly includes an electric telescopic rod, and a cutter is installed at the telescopic end of the electric telescopic rod. Both sides of the front end of the cutting assembly are equipped with slitting blades for separating the edge strip from the adhesive surface.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) In this utility model, the end of the product film is passed through the film-tearing guide roller in advance and attached to the film-tearing take-up roller. The first motor drives the film-tearing guide roller to rotate, which can drive the film on the product surface to separate from the product, thereby achieving the effect of film tearing. Before tearing the film, the product position is restricted by the feeding pressure roller, and then the product surface is blown with hot air by the first hot air blower to reduce the adhesion of the surface film, so that the film can be separated from the product more easily, avoiding the film breakage on the product caused by hard tearing, which would affect the subsequent printing and lamination process.

[0015] (2) In this utility model, the film on the unwinding roller is sequentially passed through the coating guide roller, the first coating pressure roller, and the second coating pressure roller, so that its end is attached to the coating take-up roller. The second motor is driven to rotate the coating take-up roller, which drives the film to move. The film first moves to the second hot air blower, where the hot air heats and melts the adhesive on the bonding surface. Then, it is pressed onto the product surface by the pressure of the first coating pressure roller. During the movement of the film, its edge strips contact the cutting blade and separate from the bonding surface. The electric telescopic rod drives the cutter to cut the bonding surface at both ends of the product. After that, the cut product moves to the second coating pressure roller for re-pressing. Finally, the product is sent out from the inside, while the edge strips are wound onto the coating take-up roller. The above structure can automatically perform the coating operation on the product, improving production efficiency.

[0016] (3) In this utility model, both the first and second film-coating rollers can be raised and lowered at the guide rod via a slide table. The installation height can be changed by raising and lowering the rollers, which is convenient for adjusting according to different product sizes. After adjusting to the required position, the rollers are placed in the positioning hole at that height by bolts, which makes them stable and secure. The bolts can be removed and adjusted again, which is convenient for users. Attached Figure Description

The film-peeling assembly 2 includes a feed pressure roller 201, a first hot air blower 202 installed above the side of the feed pressure roller 201, a film-peeling take-up roller 204 installed above the side of the first hot air blower 202, and a first motor 204 for driving the film-peeling take-up roller 204 to rotate at one end. 5. A film-tearing guide roller 203 is installed on the lower side of the film-tearing take-up roller 204. The end of the product film is passed through the film-tearing guide roller 203 in advance and attached to the film-tearing take-up roller 204. The first motor 205 drives the film-tearing guide roller 203 to rotate, which can drive the film on the product surface to separate from the product, thereby achieving the effect of film tearing. Before tearing the film, the product position is restricted by the feeding pressure roller 201, and then the product surface is blown with hot air by the first hot air blower 202 to reduce the adhesion of the surface film, so that the film can be separated from the product more easily, avoiding the film breakage on the product caused by hard tearing, which would affect the subsequent printing and lamination process.

[0026] Please see Figure 3 , Figure 4 , Figure 6The laminating assembly 4 includes a first laminating roller 401 and a second laminating roller 402 located at the bottom of both ends.

The second motor 407 drives the coating take-up roller 406 to rotate, causing the film 7 to move. The film 7 first moves to the second hot air blower 403, where the hot air heats and melts the adhesive on the bonding surface 702. Then, it is pressed onto the product surface by the downward pressure of the first coating pressure roller 401. During the movement of the film 7, its edge strip 701 contacts the slitting blade 408 and separates from the bonding surface 702. The electric telescopic rod 501 drives the cutter 502 to cut the bonding surface 702 at both ends of the product. After that, the cut product moves to the second coating pressure roller 402 for re-pressing. Finally, the product is sent out from the inside, while the edge strip 701 is wound onto the coating take-up roller 406.

Bolts 605 are installed in the openings on the outer walls of the slide tables 603, with one end of the bolts 605 extending into the positioning holes 604. Both the first coating roller 401 and the second coating roller 402 can be raised and lowered by sliding on the guide rods 602 via the slide tables 603, changing their installation height for easy adjustment according to different product sizes. After adjustment to the desired position, the bolts 605 are positioned within the positioning holes 604 at that height, ensuring stable and secure placement. The bolts 605 can then be removed for further adjustment, making it convenient for users.
