Description

Technical Field

[0001] The utility model belongs to the technical field of film processing, and in particular relates to a laminating roller group for polymer films. Background Art

[0002] The primary function of a film lamination roller is to ensure uniform lamination of the film onto the substrate. During extrusion coating and calender coating, lamination rollers are used in conjunction with chill and calender rollers and are typically made of rubber. This design ensures uniform lamination of the film onto the substrate, ensuring uniformity and quality during the coating process. In some cases, the lamination roller can also refer to the rubber roller used in embossing machines, which works in conjunction with an engraved roller to create a uniform emboss on the web.

[0003] The gaps between the existing polymer film laminating roller groups are mostly unable to be adjusted, resulting in poor laminating effect on thinner fabrics and inability to laminarize thicker fabrics, affecting their applicability. For this reason, we propose a polymer film laminating roller group. Utility Model Content

[0004] The purpose of the present invention is to provide a laminating roller assembly for polymer films to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a laminating roller group for a polymer film, comprising a first support frame and a second support frame, a first fixed block being provided on the inner side of the first support frame, a first connecting shaft being provided on the surface of the first fixed block, a lower laminating roller being provided between the first connecting shafts, a first slide groove being provided inside the first support frame, a slider being provided on the inner side of the first slide groove, a connecting frame being provided between the sliders, a square groove being provided inside the connecting frame, a second slide groove being provided inside the square groove, a fixing rod being provided inside the second slide groove, a spring being provided on the surface of the fixing rod, a connecting block being provided on the surface of the fixing rod, a second fixed block being provided between the connecting blocks, a second connecting shaft being provided on the surface of the second fixed block, an upper laminating roller being provided between the second connecting shafts, and a screw rod being provided on the top of the connecting frame.

[0006] Preferably, the first support frame and the second support frame have the same structure. A first fixed block is fixedly installed on the lower inner side of the first support frame. The surface of the first fixed block is rotatably connected to a first connecting shaft. A lower pressing roller is fixedly connected between the first connecting shafts.

[0007] Preferably, first sliding grooves are fixedly provided on both side surfaces of the inner portion of the first supporting frame, a slider is slidably connected to the inner side of the first sliding groove, and a connecting frame is fixedly installed between the sliders.

[0008] Preferably, second sliding grooves are fixedly provided on both side surfaces of the inner side of the square groove, a fixing rod is vertically fixedly installed inside the second sliding groove, and a spring is sleeved on the surface of the fixing rod.

[0009] Preferably, a connecting block is slidably installed on the surface of the fixed rod, the bottom end of the spring is fixedly connected to the top end of the connecting block, a second fixed block is fixedly installed between the connecting blocks, and the surface of the second fixed block is rotatably connected to a second connecting shaft.

[0010] Preferably, an upper pressing roller is fixedly connected between the second connecting shafts, and a screw rod is rotatably connected to the top of the connecting frame, and the screw rod is threadedly rotatably penetrated through the surface of the first supporting frame.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. By rotating the screw rods above the first support frame and the second support frame, the connecting frame and the slider can be driven to move vertically inside the first slide groove. The movement of the connecting frame can drive the second connecting shaft and the upper pressing roller to rise and fall, thereby achieving the effect of adjusting the pressing gap between the upper pressing roller and the lower pressing roller;

[0013] 2. The film to be laminated after spraying glue is extended between the upper laminating roller and the lower laminating roller for lamination. Different forces will be exerted on the surface of the upper laminating roller according to the thickness of the laminating film, thereby driving the connecting block to compress the spring. The elastic force generated will drive the bottom of the upper laminating roller to always fit between the film, thereby improving the quality of film lamination. BRIEF DESCRIPTION OF THE DRAWINGS
