摘要： The present invention discloses a PVC floor, and a production line and preparation method thereof. The production line comprises a feeding system, an internal mixing and extruding device, a calendering laminating device, a cooling device, a tractor, and a cutting machine arranged in sequence along a material conveying direction, wherein the internal mixing and extruding device comprises an internal mixing mechanism, an extruding mechanism, and a hopper. In the production line of the present invention, materials are rapidly dispersed and plasticized by means of an internal mixing section of the internal mixing and extruding device, and the plasticized materials directly enter an extruding section through the hopper to be subjected to extruding forming, which has a good plasticizing effect, and solves the problem of a poor plasticizing effect of traditional extruders caused by forced plasticizing of a PVC rigid product without a plasticizer; in addition, the materials do not need to pass through a high-speed mixer, and the materials are directly extruded after being plasticized, thereby shortening the mixing and extruding time of the materials, reducing energy consumption, and reducing the use of a stabilizer and internal and external lubricants in a raw material formula.

摘要： A roll forming device for plastic flooring utilizes a printed layer unwinding mechanism (20), a wear-resisting unwinding mechanism (30) and a calender to laminate a substrate layer formed by an extruder (10), a printed layer (62) and a wear-resisting layer (63) into a whole. The calender includes a gauging roller group (42), a pre-bonding roller group (43) and a laminating roller group (44) disposed on a rack (41). The gauging roller group (42), which is disposed at one side of the pre-bonding roller group (43) and linearly opposite to a discharge port (11) of the extruder (10), is configured to define the thickness of the substrate layer. The pre-bonding roller group (43) includes a large roller (431) and a plurality of guide rollers (432, 433, 434) disposed around the large roller (431), and at least one first heating unit (435) is disposed in the large roller (431) or a position corresponding to an outer edge of the roller surface thereof, and is configured to heat the substrate layer, the printed layer (62) and the wear-resisting layer (63) which are pre-bonded. The laminating roller group (44), which is disposed at the other side of the pre-bonding roller group (43), is configured to laminate the substrate layer, the printed layer (62) and the wear-resisting layer (63) into a whole.

摘要： The present invention relates to a movable laminating machine (30) and a plastic flooring laminating device using same. A laminating mechanism (32), a driving mechanism (33) and a conveying mechanism (34) assembled on a rack (31) compose the laminating machine (30) which can make continuous reciprocating movements. The movable laminating machine (30) is then disposed in an automatic production line for plastic flooring to cooperate with an extruder (10), a rolling unit (20) and a drawing mechanism (40) to laminate a plastic flooring material composed of a substrate layer (61), a printed layer (62) and a wear-resisting layer (63) into a finished plastic flooring product in an automatic operation manner. Because the time of the lamination of the material by the movable laminating machine can match the speed at which the material is conveyed and moved, the laminating mechanism is driven by the second power source to move from the front section position to the rear section position on the rack, and, after lamination is complete, is driven again by the second power source to move to the front section position for next laminating operation, and thereby the automatic continuous production operation of reciprocating lamination is accomplished.

摘要： The present application discloses a PVC floor production line, the production line comprising a feeding system, an internal mixing and extruding device, a calendering and laminating device, a cooling device, a tractor and a cutting machine which are sequentially arranged along a material conveying direction, wherein the internal mixing and extruding device comprises an internal mixing mechanism, an extruding mechanism and a hopper. According to the production line of the present application, an internal mixing section of the internal mixing and extruding device is used for quickly dispersing and plasticizing materials, and the plasticized materials directly enter an extruding section by passing through the hopper to carry our extruding and moulding, the plasticizing effect is good, and thus the problem that conventional extruders forcibly plasticize rigid PVC products that do not contain plasticizers thus leading to a poor plasticizing effect is avoided. In addition, the materials are directly extruded after being plasticized without needing to pass through a high-speed mixer, and thus the internal mixing and extruding time of the materials is shortened, energy consumption is reduced, and the usage amounts of a stabilizer and internal and external lubricants in a raw material formula are reduced.
