Description

Technical Field

[0001] The invention relates to the technical field of processing and laminating film replacement, in particular to a variable laminating roller used in the processing and production of decorative films. Background Art

[0002] Decorative film is a new type of decorative coating. Applying it to the surface of decorative materials imparts a metallic sheen, a three-dimensional effect within flat patterns, and an exceptional texture. Therefore, it is widely used in the surface processing of glass, panels, and flooring. To further enhance the three-dimensional effect of the decorative film surface, the coating surface is currently subjected to a lamination process during processing. However, the patterns on the lamination surface are mostly fixed, with one lamination roller capable of handling only one pattern, resulting in very limited applicability. To produce films with a variety of patterns, multiple lamination rollers are required. However, these multiple lamination rollers are not only inconvenient to store and expensive to process, but also prevent the pattern from being quickly changed during processing. To change, the entire machine must be stopped and the lamination roller disassembled, resulting in a long service life and significantly reducing the efficiency of the entire decorative film production process. Summary of the Invention

[0003] The technical problem to be solved by the present invention is: currently the patterns on the surface of the pressed film are mostly fixed integrated structures, and one pressing roller can only cope with one pattern, resulting in very limited applicability; and the pressing roller is not only inconvenient to store, but also has a relatively high processing cost, and it is impossible to quickly replace the pattern during the processing. If it needs to be replaced, the entire machine needs to be stopped and the pressing roller needs to be disassembled, which has a long service life and seriously reduces the production and processing efficiency of the entire decorative film.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a variable film pressing roller used for decorative film processing and production, including a main frame, an upper pressing roller and a lower pressing roller, an arc-shaped assembly adjustment groove is opened on the outer arc surface of the upper pressing roller and the lower pressing roller, a first film pressing component is movably assembled on one side of the arc-shaped assembly adjustment groove, and a second film pressing component is movably assembled on the other side of the arc-shaped assembly adjustment groove, and a lateral heat exchange module for connecting the upper pressing roller and the lower pressing roller is installed on the outer surface of the main frame.

[0005] Both side walls of the arc-shaped assembly adjustment groove are provided with lateral receiving grooves.

[0006] The first film pressing assembly includes a first internal assembly frame installed inside the lateral receiving groove, a first arc-shaped film pressing cover fixed outside the first internal assembly frame, a first hydraulic support rod and a first electric control screw rod.

[0007] The second film pressing assembly includes a second internal assembly frame installed inside the lateral receiving groove, a second arc-shaped film pressing cover fixed outside the second internal assembly frame, a second hydraulic support rod and a second electric control screw rod.

[0008] Internal heat conduction channels are provided inside the upper pressing roller and the lower pressing roller.

[0009] The internal heat conduction channel includes lateral inlet holes, lateral return holes and N-shaped external liquid conduction channels located on both sides of the inner center of the upper pressure roller and the lower pressure roller.

[0010] The lateral inlet hole and the lateral return hole are connected through an N-shaped external liquid guide channel, and a gravity sealing cover plate is provided at the connecting end of the N-shaped external liquid guide channel and the lateral inlet hole and the lateral return hole.

[0011] A lateral infrared positioning switch is fixedly mounted on the inner side of the main frame, and a lateral infrared receiving switch matched with the lateral infrared positioning switch is fixedly mounted on the side walls of the upper and lower pressing rollers.

[0012] The extended ends of the first hydraulic support rod and the first electric control screw rod are movably assembled with the two ends of the first internal assembly frame respectively, and the extended ends of the second hydraulic support rod and the second electric control screw rod are movably assembled with the two ends of the second internal assembly frame respectively.

[0013] The lateral heat exchange module includes a first air guide cover connecting the lateral inlet hole of the upper pressure roller and the lateral return hole of the lower pressure roller, a second air guide cover connecting the lateral return hole of the upper pressure roller and the lateral inlet hole of the lower pressure roller, and an electrically controlled water pump installed on the inner bottom surface of the second air guide cover.

[0014] The beneficial effects of the present invention are:

[0015] (1) The variable lamination roller used in the production of decorative films of the present invention adopts a variable lamination surface design, and the lamination surface can be replaced as needed during operation, thereby greatly reducing switching costs;

[0016] (2) The first film pressing assembly and the second film pressing assembly are designed to be detachable and can be replaced as needed to improve their applicability;

[0017] (3) The entire device adopts an embedded structure design, which does not require an additional external storage mechanism, greatly improving space utilization;

[0018] (4) By installing a lateral heat exchange module on the outer side of the main frame for connecting the upper and lower pressure rollers, heat can be circulated between the upper and lower layers, thereby improving the heat recovery rate inside the film roller and reducing waste;

[0019] (5) The heat is always circulated at the film pressing end, which can greatly improve the utilization rate of heat and make the heat energy more concentrated;

[0020] (6) The entire device has a compact structure and a reasonable layout, and does not occupy excess external space. BRIEF DESCRIPTION OF THE DRAWINGS
