DETAILED DESCRIPTION

[0026] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0027] The term "multiple" as used herein refers to two or more than two. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship.

[0028] Figure 1It is the front view of the SPC floor sheet calendering and laminating device. The production line uses a dual-channel extruder as the input end for sheet production, which respectively produces the upper and lower surface materials of the SPC floor. The device mainly receives the calendered surface material and calenders it to form the SPC floor. The device specifically includes a five-roll calender 10, a sheet conveying guide plate 20 and a bottom film laminating device 30. The sheet conveying guide plate 20 is arranged at the input port of the five-roll calender 10, and the upper and lower guide plate surfaces of the sheet conveying guide plate respectively convey the loading plate and glass fiber through a series of guide rollers, and the loading plate and glass fiber are conveyed to the five-roll calender 10.

[0029] Because the floor is made and calendered in layers in the embodiment of the present application, the calender must be fed into the calender in the order of the upper plate, glass fiber and lower plate. In order to arrange the production line reasonably, the upper and lower plates and glass fiber are arranged in the structural layers and fed into the calender. Therefore, in addition to the sheet conveying guide 20, a conveying device for the lower plate is also provided at the bottom of the sheet conveying guide 20 to feed the lower plate into the five-roll calender 10.

[0030] The five-roll calender 10 includes five rollers, which calender and coat the feeding upper plate, glass fiber and lower plate. The bottom film coating device 30 is located below the five-roll calender 10, and includes two coating rollers, which respectively feed the PVC bottom film into the five-roll calender 10, and the five-roll calender 10 coats the PVC bottom film to form a floor balance layer.

[0031] See also Figure 2 As shown in the figure, in a possible embodiment, the sheet conveying guide plate 20 is tilted, the top surface of the sheet conveying guide plate 20 conveys the loading plate through the first transmission roller 21, and the bottom surface conveys the glass fiber through the second transmission roller 22. The unloading plate is directly fed into the five-roll calender 10 from below the second transmission roller 22. Thus, the five-roll calender 10 rolls and forms the loading plate, the glass fiber and the unloading plate according to the stacking.

[0032] The calender is a key equipment for sheet calendering and laminating. This application sets a five-roller structure according to the function. Figure 3 It is a simplified schematic diagram of a five-roller structure. The five-roller calender specifically includes a pattern roller 11, a frosted roller 12, a mirror roller 13, a silicone roller 14 and a pattern roller 15 arranged in sequence. The pattern roller 11 is in contact with the frosted roller 12, and the silicone roller 14 is in contact with the pattern roller 15. The sheet and glass fiber input from three paths are fed into the roller between the pattern roller 11 and the frosted roller 12, and are rolled between the silicone roller 14 and the pattern roller 15 to form the SPC floor.

[0033] At the entrance of the pressing roller, the upper material plate, the glass fiber and the lower material plate are stacked up and down and fed between the pattern roller 11 and the grinding roller 12. The pattern roller 11 is used to roll the pattern on the bottom surface of the lower material plate, while the grinding roller 12 is used to calender the top surface of the upper material plate, and the glass fiber is rolled between the two sheets.

[0034] In some embodiments, the frosted roller 12, the mirror roller 13, the silicone roller 14 and the pattern roller 15 can be arranged horizontally, and the pattern roller 11 can be arranged below the horizontal position of the frosted roller 12, specifically, they can be arranged vertically or obliquely, as long as the output end of the sheet conveying guide 10 is aligned with the contact position of the pattern roller 11 and the frosted roller 12. The sheet after rolling is conveyed to the mirror roller 13.

[0035] The mirror roller 13 is mainly used to coat the sheet with a color film to obtain a smoother coated surface. The sheet passing through the mirror roller 13 is fed into the silicone roller 14 and the pattern roller 15 for rolling, and the pattern is rolled on the top surface of the sheet and then the shaped floor is output. The silicone roller 14 is used to coat the bottom surface of the sheet with silicone, while the pattern roller 15 is used to roll the pattern on the top surface and output the shaped SPC floor.

[0036] Of course, for the floor, in addition to completing the basic function of the upper and lower floor calendering indication, some high-composite floors also need to be provided with a protective layer and an embossed color film to achieve the purpose of beauty and durability. Therefore, a bottom film device 30 can also be provided at the bottom of the five-roll calender 10. Figure 3 As shown, the bottom film coating device 30 specifically includes a first coating roller 31 and a second coating roller 32. The two coating rollers are double-station, one main and one backup, and are used to coat the PVC bottom film on the blanking plate, that is, the first coating roller is used to convey the first balancing film layer, or the second coating roller is used to convey the second balancing film layer.

[0037] Specifically, the first laminating roller 31 transfers the prepared first balancing film layer to the mirror roller 13, and the second laminating roller 32 transfers the prepared second balancing film layer to between the pattern roller 11 and the frosted roller 12. In particular, the conveying direction of the second laminating roller 32 is opposite to the conveying direction of the feed plate, and the PVC film is pulled to the connection between the two rollers by rolling. The second balancing film layer is rolled to the bottom of the blanking plate by the pattern roller 11 and rolled into shape.

[0038] Correspondingly, the first balancing film layer is transported to the gap between the mirror roller 13 and the frosted roller 12, and is covered under the sheet, that is, rolled under the second balancing film layer. In some embodiments, the first laminating roller 31 and the second laminating roller 32 can be arranged horizontally or tilted, and are separately transported to the target position by a plurality of spiral rollers.

[0039] Specifically, for the wear resistance and aesthetics of the floor, a pattern laminating device 40 may be provided on the upper part of the five-roll calender 10. Figure 1 and Figure 4As shown, the laminating device 40 conveys the wear-resistant layer laminating and the color film layer laminating to the five-roll calender 10 below through a plurality of rollers and a conveying mechanism. At a position close to the mirror roller 13, at least two laminating rollers 41 and a plurality of spiral rollers 42 are included. The two laminating rollers 41 are in contact with the mirror roller 13 respectively, and convey the wear-resistant layer and the color film layer laminating to the mirror roller 13 respectively, and then roll out the color film layer and the wear-resistant layer on the surface of the frosted feeding plate. Specifically, the two laminating rollers 41 are arranged and transmitted in opposite directions, and the conveying path of the wear-resistant layer and the color film layer laminating is adjusted by the spiral roller, and finally conveyed to the contact position between the laminating roller 41 and the mirror roller 13.

[0040] After passing through the mirror roller 13, the plate is further conveyed to the connection between the silicone roller 14 and the pattern roller 15. The pattern roller 15 contacts the upper surface of the plate, and a specific pattern is rolled out on the upper film; while the silicone roller 14 contacts the lower surface, and rolls out a silicone layer at the bottom of the floor to improve wear resistance. The final output of the molded SPC floor is subsequently transported to the subsequent production line to perform related processes. For example, the roller conveyor line is connected to the output end of the five-roll calender to transfer and assemble the molded floor.

[0041] In summary, the production line realizes three-way synchronous operation by using the sheet conveying guide to convey the front and back sides separately, and stacks them in the calendering order, and inputs them into the calender for calendering. The five-roll calender is set according to the functional settings of the floor, and at the same time combines the bottom and top coating requirements. The corresponding pattern coating device and bottom coating device are set on the upper and lower rollers to realize the simultaneous calendering of multiple film layers and improve the production efficiency of the production line. In the entire production process, the steps of substrate forming, film lamination, plasticity, cutting, etc. are all completed through an automated production line, replacing the complex and fragmented processing technology of traditional LVT floors, and occupying less space and cost investment, convenient operation, and higher production efficiency.
