Description

Technical Field

[0001] This utility model relates to a laminating machine, and more particularly to a laminating machine pressing mechanism. Background Technology

[0002] A laminating machine is a device that coats a plastic film with adhesive, then bonds it to printed materials on a paper substrate under pressure using pressing and heating rollers, forming a paper-plastic composite product. The laminated printed materials have a smoother and glossier surface due to the thin, transparent plastic film, which not only improves the gloss and durability of the print and extends its lifespan, but also provides protection against water, stains, abrasion, folding, and chemical corrosion.

[0003] The current laminating machine's pressing mechanism mainly consists of a frame, a heating roller mounted on the frame, a pressing roller located on one side of the heating roller, and two sets of adjusting components that drive the pressing roller to move towards the heating roller. The two sets of adjusting components are connected to opposite ends of the pressing roller, and the existing adjusting components include cylinders and a linkage structure connecting the cylinders and the pressing roller. This structure requires two drive sources, which undoubtedly increases the equipment's manufacturing cost significantly. Furthermore, using two independent drive sources leads to a certain degree of adjustment deviation at both ends of the pressing roller, resulting in uneven force on both sides of the substrate, affecting the stability of substrate transport, and ultimately negatively impacting the lamination quality of the substrate. To address these issues, this improved solution has been developed. Utility Model Content

[0004] The purpose of this invention is to provide a laminating machine pressing mechanism that can achieve smooth adjustment of the pressing roller, thereby improving the laminating quality and the reliability of the mechanism.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a laminating machine pressing mechanism, including a frame, a heating roller mounted on the frame, and a pressing roller disposed on one side of the heating roller. An elastic component is connected between the pressing roller and the frame to drive the pressing roller to move away from the heating roller. The frame is provided with a counteracting adjustment component that moves the pressing roller toward the heating roller. The counteracting adjustment component has two counteracting force points that simultaneously apply force to both ends of the pressing roller.

[0006] By adopting the above technical solution, the abutment adjustment component applies abutment force synchronously to both ends of the pressing roller through two abutment force application points, compressing the elastic component, thereby adjusting the distance between the pressing roller and the heating roller. This structure requires only one drive source to achieve synchronous adjustment control of both ends of the pressing roller, thereby achieving smooth adjustment of the pressing roller, improving coating quality and the reliability of the mechanism.

[0007] Further configured as follows: the elastic component includes a sliding structure and an elastic element. The sliding structure includes a groove disposed on the frame and corresponding to the two ends of the pressing roller, and two sliders respectively slidably disposed in the groove. The two ends of the pressing roller are respectively rotatably disposed on the two sliders. The extension direction of the groove length intersects with the heating roller.

[0008] By adopting the above technical solution, the slider and the groove structure are used to change the position of the pressing roller, thereby realizing the adjustment of the distance between the pressing roller and the heating roller.

[0009] The further configuration is as follows: two elastic elements are provided, each corresponding to one of the two sliders and installed below the sliders. The sliders and the groove wall abutting against the elastic elements are provided with positioning grooves for the elastic elements to be embedded.

[0010] By adopting the above technical solution, the elastic element is equipped with a counteracting adjustment component to control the reciprocating movement of the pressing roller toward the heating roller side to achieve the adjustment purpose; and the positioning groove is provided to facilitate the easy assembly and disassembly of the elastic element, making the operation more convenient.

[0011] The further configuration includes: the abutting adjustment assembly comprising a synchronous shaft rotatably mounted on the frame, two abutting eccentric wheels mounted on the synchronous shaft and respectively abutting against both ends of the pressing roller, and a drive component connected to the synchronous shaft.

[0012] By adopting the above technical solution, the driving component drives the synchronous shaft to drive the two clamping eccentric wheels to rotate synchronously. By having the two clamping eccentric wheels abut against the pressing roller near its two ends, the pressing roller is driven to move toward the heating roller, so as to precisely adjust the distance between the two.

[0013] The configuration is further improved by providing rotating components at the positions where the pressing roller is pressed against the eccentric wheel.

[0014] By adopting the above technical solution, the rotating component is designed to achieve rolling contact between the pressing roller and the clamping eccentric wheel, thereby reducing friction and extending the service life of the components.

[0015] The heating drum is further configured such that: a drive motor is connected to the heating drum; a heating cylinder with a heating chamber is provided inside the heating drum; a heating element is provided inside the heating cylinder; an isolation chamber is formed between the heating drum and the heating cylinder; and the heating drum and the heating cylinder rotate relative to each other.

[0016] By adopting the above technical solution, the isolation chamber can better mix air and conductive heat, allowing heat to diffuse and conduct outward more evenly through the isolation chamber, thereby improving the heating quality.

[0017] A further feature is provided: the inner wall of the heating drum is provided with agitator blades.

[0018] By adopting the above technical solution, the stirring blades can further mix the heat in the isolation chamber as the heating drum rotates, so that the heat can be conducted outward more evenly.

[0019] In summary, this utility model has the following beneficial effects: it can achieve stable adjustment of the pressing roller, thereby improving the coating quality and the reliability of the mechanism. Attached Figure Description
