Description

Technical Field

[0001] The utility model relates to the technical field of laminating mechanisms, in particular to a laminating mechanism. Background Art

[0002] Lamination is a key post-printing process. It involves heating and pressurizing a plastic film coated with an adhesive to bond it to a printed paper, creating a fused paper and plastic product. It's a common post-printing process for printed paper. Laminated printed materials, thanks to the additional layer of thin, transparent plastic film, have a smoother, brighter surface. This not only improves the gloss and durability of the printed material, extending its lifespan, but also provides protection against moisture, water, stains, abrasion, folding, and chemical corrosion.

[0003] During continuous production, the film on the surface of urea bags needs to be frequently cut off. During this process, due to common industrial problems such as air flow disturbance in the production line and electrostatic adsorption, it is easy for the active end of the film to float upward after being cut off, and then adsorb to the film column, causing the subsequent urea bags to pass directly under the film column without being coated, resulting in film failure. Utility Model Content

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] To this end, the technical solution adopted in this utility model is:

[0006] A film laminating mechanism includes a feeding mechanism, a film sealing mechanism and a cutting mechanism, the feeding mechanism includes a support frame, a belt conveyor movably installed inside the support frame, a film sealing mechanism, the film sealing mechanism includes two hydraulic cylinders sliding through the top of the support frame, a U-shaped plate connected between the two hydraulic cylinders, a film laminating column adhered to the top of the belt conveyor and rotatably connected to the U-shaped plate, and a cutting mechanism, the cutting mechanism includes two cylinders respectively arranged on the front and rear sides of the belt conveyor and connected to the support frame, a machine cover connected to the movable end of the cylinder, a motor connected to the machine cover, a rubber plate 1 connected between the two motors, a plastic arc plate connected to the top of the rubber plate 1, a rubber plate 2 connected to the top of the plastic arc plate, and a blade running through the plastic arc plate.

[0007] By adopting the above technical solution, after the laminating column has finished laminating a urea bag, the cylinder piston rod extends, driving the machine sleeve and the motor and rubber plate 1 thereon to move as a whole, so that the rubber plate 1 is inserted between the laminating column and the urea bag that has been laminarly formed, pressing the movable end of the film. Then the motor is started, and the rubber plate 2 and the blade are driven to rotate through the plastic arc plate. The rubber plate 2 stretches the film and presses it onto the subsequent urea bag. When the rubber plate 2 flips over to be parallel to the top plane of the belt conveyor, the blade cuts the film between two adjacent urea bags, thereby effectively avoiding the film floating phenomenon.

[0008] In a preferred example, the present invention can be further configured as follows: two hydraulic cylinders are respectively close to the two ends of the U-shaped plate, and the two hydraulic cylinders are connected in series.

[0009] In a preferred example, the present invention can be further configured as follows: two springs are connected between the bottom of the support frame and the top of the U-shaped plate, the two springs are respectively sleeved on the outside of the two hydraulic cylinders, and the diameter of the springs is smaller than the width of the U-shaped plate.

[0010] In a preferred example, the present invention can be further configured as follows: two cylinders are connected in series, two motors are connected in series, and the hydraulic cylinder, cylinder, and motor are all electrically connected to an external PLC.

[0011] In a preferred example, the present invention can be further configured as follows: the rubber plate 1, the plastic arc plate, and the rubber plate 2 are all arranged obliquely, and the bottom end of the rubber plate 1 movably extends to between the belt conveyor and the coating column.

[0012] In a preferred example, the present invention can be further configured as follows: the bottom of the first rubber plate and the top of the second rubber plate are both arranged with inclined surfaces, and the outer sides of the inclined surfaces are processed into arc surfaces.

[0013] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0014] 1. In the utility model, after the laminating column has finished laminating one urea bag, the cylinder piston rod extends, driving the machine housing and the motor and rubber plate 1 thereon to move as a whole, so that the rubber plate 1 is inserted between the laminating column and the urea bag that has been laminar-formed, pressing the movable end of the film. Then the motor is started, driving the rubber plate 2 and the blade to rotate through the plastic arc plate. The rubber plate 2 stretches the film and presses it onto the subsequent urea bag. When the rubber plate 2 flips over to be parallel to the top plane of the belt conveyor, the blade cuts the film between two adjacent urea bags, thereby effectively preventing the film from floating.

[0015] 2. In the present invention, when the second rubber sheet is turned over, the piston rod of the hydraulic cylinder contracts, driving the laminating column to rise, making room for the turning of the second rubber sheet, so that the film pressing operation can proceed smoothly.

[0025] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0026] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0027] A laminating mechanism provided by some embodiments of the present invention will be described below with reference to the accompanying drawings.

[0028] Example 1: Combination Figure 1-4 As shown, the present invention provides a laminating mechanism, comprising a feeding mechanism 100, a film sealing mechanism 200 and a cutting mechanism 300, wherein the feeding mechanism 100 comprises a support frame 110 and a belt conveyor 120 movably mounted inside the support frame 110;

[0029] The film sealing mechanism 200 includes two hydraulic cylinders 210 that slide through the top of the support frame 110, a U-shaped plate 220 connected between the two hydraulic cylinders 210, and a film covering column 230 that is attached to the top of the belt conveyor 120 and rotatably connected to the U-shaped plate 220;

[0030] The cutting mechanism 300 includes two cylinders 310 respectively provided on the front and rear sides of the belt conveyor 120 and connected to the support frame 110, a machine sleeve 320 connected to the movable end of the cylinder 310, a motor 330 connected to the machine sleeve 320, a rubber plate 1 340 connected between the two motors 330, a plastic arc plate 350 connected to the top of the rubber plate 1 340, a rubber plate 2 360 connected to the top of the plastic arc plate 350, and a blade 370 passing through the plastic arc plate 350.

[0031] Furthermore, the two hydraulic cylinders 210 are respectively close to the two ends of the U-shaped plate 220, and the two hydraulic cylinders 210 are connected in series. With this connection method, the piston rods of the two hydraulic cylinders 210 can be synchronously extended and retracted, effectively preventing the U-shaped plate 220 from being stuck during lifting.

[0032] Furthermore, the two cylinders 310 are connected in series, and the two motors 330 are connected in series. The hydraulic cylinder 210, the cylinder 310, and the motor 330 are all electrically connected to an external PLC. Using an external PLC can improve the ease of use of the device.

[0033] Furthermore, the rubber plate 1 340, the plastic arc plate 350, and the rubber plate 2 360 are all arranged at an angle, and the bottom end of the rubber plate 1 340 is movably extended to between the belt conveyor 120 and the coating column 230. This layout makes it convenient for the rubber plate 1 340 to be inserted between the urea bag and the coating column 230, ensuring that the rubber plate 1 340 can press the film at the end of the urea bag.

[0034] Example 2: Combination Figure 1 and Figure 3 As shown, on the basis of Example 1, two springs 400 are connected between the bottom of the support frame 110 and the top of the U-shaped plate 220. The two springs 400 are respectively sleeved on the outside of the two hydraulic cylinders 210. The diameter of the spring 400 is smaller than the width of the U-shaped plate 220. The spring 400 is provided to squeeze the coating column 230 under the U-shaped plate 220 so that the coating column 230 always fits tightly against the urea bag to ensure the coating effect.

[0035] Example 3: Combination Figure 1 and Figure 4 As shown, in the above embodiment, the bottom of the rubber plate 1 340 and the top of the rubber plate 2 360 are both inclined, and the outer side of the inclined surface is processed into a curved surface. The curved surface design prevents the rubber plate 1 340 and the rubber plate 2 360 from puncturing the film.

[0036] When the film is formed, the second urea bag 360 is moved to the next position, and the film is gradually formed on the second urea bag 360.

[0037] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
