According to the seven-roller calendering laminating equipment, a heat preservation conveying roller mechanism is omitted, a base material with the thickness fixed by the thickness fixed roller set directly enters the shading pre-laminating roller set to be laminated with a back laminating film and press shading, and the distance between the thickness fixed roller set and the shading pre-laminating roller set is shortened; meanwhile, due to the fact that a heat preservation conveying roller mechanism arranged in the horizontal direction is omitted, the abrasion-resistant layer unwinding machine and the color film unwinding machine are located on the upper-layer frame body, the back pasting film unwinding machine is arranged on the lower-layer frame body, and the back pasting film unwinding machine is located on the lower-layer frame body. Therefore, the occupied area of the seven-roller calendering and laminating equipment is reduced.

Description

Technical Field

[0001] The utility model relates to the technical field of floor manufacturing, in particular to a seven-roller calendering and laminating device. Background Art

[0002] In the existing LVT floor laminating technology, the back-laminating calender includes a two-roller thickness setting mechanism, a heat-insulating conveying roller, a back-laminating film placing mechanism and a bottom film laminating mechanism. After the product substrate is extruded by the extruder, it is thickness-set by the two rollers of the back-laminating calender and then transported through the heat-insulating conveying roller. The heat-insulating conveying roller is equipped with electric heating to ensure the temperature of the substrate. After the back-laminating film comes out, it is laminated together with the substrate through the bottom film laminating mechanism.

[0003] During the process of laminating the back film of the floor, the substrate needs to have a certain temperature. Therefore, when the heat-insulating conveyor roller is conveying the substrate, the substrate on the heat-insulating conveyor roller is mostly insulated by a film temperature controller and a heating lamp to ensure the temperature required for the laminating process. Therefore, the back film process consumes a lot of energy and the back film calender occupies a large space along the length direction. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0027] like Figure 1 As shown, this embodiment provides a seven-roll calendering laminating device, which includes a frame 2 arranged horizontally adjacent to an extruder 1, and the frame 2 is provided with an upper frame, a middle frame and a lower frame arranged in sequence from top to bottom.

[0028] The outlet of the extruder 1 is adjacent to the middle frame, and the thickness setting roller group 3, the pre-pasting shading roller group 4, the laminating roller group 5 and the embossing roller group 6 are arranged in sequence from the proximal end to the distal end of the extruder 1 on the middle frame (from near to far from the extruder 1). The colored film unwinder 10, the color film unwinder 9 and the wear-resistant layer unwinder 8 are arranged in sequence on the upper frame from the proximal end to the distal end, and the back film unwinder 7 is arranged on the lower frame. In the seven-roll calendering and laminating equipment, the thickness setting roller group 3 is used to set the thickness of the substrate extruded by the extruder 1, the pre-laminating shading roller group 4 is used to laminate and emboss the back film output by the back film unwinder 7, the substrate after thickness setting and the colored film output by the colored film unwinder 10, the laminating roller group 5 is used to laminate the color film output by the color film unwinder 9 and the wear-resistant layer output by the wear-resistant layer unwinder 8 with the substrate after shading, and the embossing roller group 6 is used to press the surface texture of the substrate after laminating by the laminating roller group 5 to form a composite floor. The opening and closing of the colored film unwinder 10 can be selected according to actual needs. Figure 3 As shown in the figure, the materials of the composite floor can be the wear-resistant layer, the color film, the base material and the back film in sequence, or as shown in the figure, ... Figure 2 The materials of the composite floor shown are wear-resistant layer, color film, colored film, base material and back film.

[0029] The seven-roller calendering and laminating equipment in this embodiment omits the heat-insulating conveying roller mechanism, so that the substrate that has been thickness-fixed by the thickness-fixing roller group 3 directly enters the pre-pasting shading roller group 4 for laminating and embossing the back film, shortening the distance between the thickness-fixing roller group 3 and the pre-pasting shading roller group 4, thereby avoiding the need to set up a film temperature controller and a heating lamp, thereby reducing the energy consumption required for the calendering and laminating equipment. At the same time, since the heat-insulating conveying roller mechanism set in the horizontal direction is cancelled, and the wear-resistant layer unwinder 8 and the color film unwinder 9 are located on the upper frame, and the back film unwinder 7 is set on the lower frame, the floor space of the seven-roller calendering and laminating equipment is reduced.

[0030] like Figure 1As shown, the pre-laminating shading roller group 4 includes a pre-laminating roller group unit 4a, a shading roller group unit 4b and a flattening roller group unit 4c. The colored film output by the colored film unwinder 10 and the back film output by the back film unwinder 7 are flattened and de-bubbled by the flattening roller group unit 4c, and are respectively located on the upper and lower sides of the substrate after the thickness is set. The colored film, the substrate after the thickness is set, and the back film enter the pre-laminating roller group unit 4a for pre-lamination and then enter the shading roller group unit 4b for lamination and embossing. The lamination pressure of the shading roller group unit 4b is greater than the lamination pressure of the pre-laminating roller group unit 4a. Among them, the diameter of the roller in the pre-laminating roller group unit 4a is smaller than the diameter of the roller in the shading roller group unit 4b, the diameter of the roller in the pre-laminating roller group unit 4a is smaller than the diameter of the roller in the embossing roller group 6, and the diameter of the roller in the pre-laminating roller group unit 4a is 80-150mm. Each of the pre-laminating roller group unit 4a, the shading roller group unit 4b and the embossing roller group 6 unit includes two rollers, among which the seven-roller designated thickness roller group 3 in the seven-roller calendering laminating equipment has two rollers, the two rollers of the shading roller group unit 4b and the two rollers of the embossing roller group 6 unit, and one large-diameter roller in the laminating roller group 5. During the production process, the two rollers of the thickness setting roller group 3, the two rollers of the shading roller group unit 4b and one large-diameter roller in the laminating roller group 5 are heated by roller oil, and the temperature is controllable, and the two rollers of the embossing roller group 6 unit are cooled by water cooling, and the temperature is controllable.

[0031] In this embodiment, in order to improve the lamination quality of the composite floor, a flattening roller unit 4c is added. Since the roller diameter of the pre-lamination roller unit 4a is small, the flattening roller unit 4c is as close to the entrance end of the pre-lamination roller unit 4a as possible, thereby improving the reliability of the flattening roller unit 4c in flattening and removing bubbles.

[0032] In order to achieve a better flattening effect, the distance between the flattening tangent point of the film in the flattening roller unit 4c and the film laminating point in the pre-laminating roller unit 4a is 80-300 mm.

[0033] Of course, the seven-roll calendering laminating equipment also includes a colored film preheating roller 11, a back film preheating roller 12 and a back film tensioning roller 13. After the colored film is output by the colored film unwinding machine 10, it is heated by the colored film preheating roller 11 and then enters the flattening roller group unit 4c in the pre-laminating shading roller group 4. After the back film unwinding machine 7 outputs the back film, it is heated by the back film preheating roller 12 and tensioned by the back film tensioning roller 13 in sequence and then enters the flattening roller group unit 4c in the pre-laminating shading roller group 4.

[0034] To facilitate the lamination of the laminating roller group 5, the seven-roller calendering laminating equipment also includes a first angle adjustment roller 14 and a second angle adjustment roller 15. The color film output by the color film unwinding machine 9 enters the laminating roller group 5 after the angle is adjusted by the first angle adjustment roller 14, and the wear-resistant layer output by the wear-resistant layer unwinding machine 8 enters the laminating roller group 5 after the angle is adjusted by the second angle adjustment roller 15.

[0035] In order to facilitate the installation and movement of the back film unwinding machine, the seven-roller calendering laminating equipment also includes a transfer trolley 16, which is used to place the back film unwinding machine 7.

[0036] To improve production efficiency, the color film unwinding machine 9 includes two parallel color film unwinding rollers, and / or the wear-resistant layer unwinding machine 8 includes two parallel wear-resistant layer unwinding rollers, and / or the back film unwinding machine 7 includes two parallel back film unwinding rollers, and / or the colored film unwinding machine 10 includes two parallel colored film unwinding rollers. The parallel unwinding rollers are all provided with films. When one unwinding roller is in normal use, the other unwinding roller is in standby. When the film on one unwinding roller is completely used, the other standby unwinding roller immediately starts to work.
