Description

Technical Field

[0001] This utility model relates to the field of cardboard lamination technology, and in particular to a heat-stamping lamination device for cardboard boards used in carton production. Background Technology

[0002] Paperboard, also known as cardboard, is a thick sheet of paper made from various pulps and interwoven fibers. Lamination involves coating a plastic film with adhesive and then bonding it to printed materials on paper substrates under pressure using rubber and heated rollers to form a paper-plastic composite product. In carton production, lamination equipment is used to coat the surface of the cardboard with a thin, transparent plastic film, making the surface smoother and glossier. This not only improves the gloss and durability of the printed materials and extends their lifespan, but the plastic film also provides protection against water, dirt, abrasion, folding, and chemical corrosion.

[0003] A paperboard heat-stamping laminating device with publication number CN209718869U is described. This patent uses a fixed cutter and a movable cutter to cut simultaneously, which effectively increases the number of cutters operating at the same time during slitting to improve efficiency.

[0004] In their daily work, the inventors discovered that the height of the glue spreading roller assembly of the aforementioned paperboard heat-stamping laminating device could not be adjusted. Since the thickness of paperboard varies, when encountering paperboards that are thin or thick, the glue spreading roller assembly would not be able to adhere to the surface of the paperboard, resulting in poor flexibility.

[0028] Reference Figure 1-5 As shown in this embodiment, the surface of the base plate 1 is provided with a limiting device 3 for limiting the position of the coating assembly. The limiting device 3 includes a groove 304 formed on the surface of the base plate 1 and a vertical strip plate 305 that slides on the inner wall. A limiting ring 306 is fixedly installed on the top surface of the vertical strip plate 305.

An insertion rod 309 is fixedly installed on the surface of the displacement plate 308. An insertion hole 310 is formed on the surface of the base plate 1. A rectangular plate 311 is fitted on the side of the vertical strip plate 305. A spring 312 is fixedly installed between the rectangular plate 311 and the displacement plate 308. The coating assembly includes an extension plate 301 that is fixedly installed on the side of the U-shaped plate 201. A rotating rod 302 is rotatably connected to the surface of the extension plate 301. A coating roller 303 is fixedly installed on the outer wall surface of the rotating rod 302.

[0029] Working principle: When the device is needed, firstly, start the conveyor belt 4 and place the outer paperboard on the surface of the conveyor belt 4. At the same time, pour a certain amount of adhesive into the glue box 6 according to the actual needs. At this time, the adhesive inside flows to the surface of the paperboard through the through hole 7. Then, the conveyor belt 4 moves the paperboard to the right to the glue roller 206 to smooth the adhesive. Next, when it moves to the bottom of the laminating roller 303, the film head of the laminating roll, which is pre-set on the surface of the laminating roller 303, is passed between the two guide rollers 9 and attached to the top of the glued paperboard. After that, when it moves to the bottom of the cooling frame 11, the motor 13 is started. The motor 13 starts and drives the fan 14 to rotate. The fan 14 blows airflow to... The paperboard with the film applied is dried. When the paperboard moves to the bottom of heater 18, heater 18 is activated to generate heat and transfer it to pressure strip 19. Then, cylinder 17 is activated, which moves heater 18 and pressure strip 19 downwards, so that pressure strip 19 contacts the top of the paperboard for heat treatment. When the height of the coating roller 206 needs to be adjusted according to the thickness of the paperboard during subsequent lamination, the double-headed electric telescopic rod 212 is activated first. This causes the two sliding plates 209 to move away from or towards each other on the surface of the slide rod 208. The movement of the two sliding plates 209 on the surface of the slide rod 208 causes the hinge plate 210 to move. The movement of the receiving plate 210 causes the coating rack 204 to move upward or downward. This upward or downward movement of the coating rack 204 causes the sliding plate 203 to move upward or downward within the vertical groove 202. Simultaneously, the upward or downward movement of the coating rack 204 ultimately causes the coating roller 206 to move upward or downward. When the coating roller 206 reaches the appropriate position, the double-headed electric telescopic rod 212 is closed. This allows adjustment of the distance between the coating roller 206 and the conveyor belt 4, enabling the coating roller 206 to coat cardboard of different thicknesses, improving the flexibility of the device. When the laminating roll is used up and needs to be replaced, first slide the displacement plate 308, causing it to move within the strip groove 307. The movement of the displacement plate 308 inside the strip groove 307 compresses the spring 312, causing the spring 312 to be compressed. At the same time, the movement of the displacement plate 308 inside the strip groove 307 also drives the insertion rod 309 to move. The movement of the insertion rod 309 causes it to move out of the insertion hole 310. The separation of the insertion rod 309 and the insertion hole 310 causes the vertical strip plate 305 to lose its limit inside the groove 304. At this time, the vertical strip plate 305 can be slid, allowing it to move inside the groove 304. The movement of the vertical strip plate 305 inside the groove 304 drives the limiting ring 306 to move, causing the limiting ring 306 to move away from the surface of the coating roller 303. This allows a new coating roll to be fitted onto the coating roller 303, providing convenience for easy replacement of the coating roll.
