Description

Technical Field

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

[0002] Decorative film is a new type of decorative material coating. By setting it on the surface of decorative materials, it can make the surface have metallic luster, prominent three-dimensional sense in flat patterns, and outstanding texture. Therefore, it is widely used in glass, plate, and floor surface processing. In order to further increase the three-dimensional sense of the decorative film surface, the coating surface is currently subjected to a film pressing and shaping process during the processing. However, the patterns on the film surface are mostly fixed integrated mechanisms, and one pressing roller can only handle one pattern, resulting in very limited applicability. In order to produce films with multiple patterns, multiple pressing rollers need to be prepared. However, multiple pressing rollers are not only inconvenient to store, but also have high processing costs. In addition, the pattern cannot be quickly replaced during the processing. If it needs to be replaced, the entire machine needs to be stopped and the pressing roller needs to be disassembled. The service life is long, which seriously reduces the production and processing efficiency of the entire decorative film. 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, the upper pressing roller and the lower pressing roller are provided with arc-shaped assembly adjustment grooves on the outer arc surfaces, a first film pressing assembly is movably assembled on one side of the arc-shaped assembly adjustment groove, and a second film pressing assembly 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] The two side walls of the arc-shaped assembly adjustment groove are both provided with lateral receiving grooves.

[0006] The first film pressing assembly comprises 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 lead screw.

[0007] The second film pressing assembly comprises 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 lead screw.

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

[0009] The internal heat conduction flow channel comprises lateral inlet holes, lateral return holes and an N-shaped external liquid conduction flow channel 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 arranged 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 pressure 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.
