Description

Technical Field

[0001] The utility model relates to the technical field of PVC floors, in particular to a PVC floor capable of being chamfered by online molding. Background Art

[0002] PVC floor is a new type of lightweight floor decoration material that is very popular in the world today. It is also called lightweight floor material. It is a popular product in Europe, America, Japan and South Korea in Asia. It is popular abroad. PVC floor is made of polyvinyl chloride material. It is made of polyvinyl chloride and its copolymer resin as the main raw materials, and is added with fillers, colorants and other auxiliary materials. It is produced on a sheet-like continuous substrate through coating process or calendering, extrusion or extrusion process. In order to improve the three-dimensional effect and overall texture of the floor, PVC floor manufacturers on the market usually perform molded chamfering on the floor. Molded chamfering refers to the use of precise CNC molding technology, hot pressing molding at standard temperature and precise time to directly generate the four-side chamfers of the floor.

[0003] The patent document with application number CN202123001479.5 discloses an online molded chamfered PVC floor and its equipment, including a floor body, wherein the floor body includes an SPC substrate, a decorative layer and a wear-resistant layer, and the floor body includes a first assembled floor and a second assembled floor, and the first assembled floor and the second assembled floor are mutually clamped. The online molded chamfered PVC floor uses an arc chamfer, which makes the entire floor clearly layered in appearance. Due to the extensibility of the chamfered color film, the overall effect is highly unified, and there is no problem of paint peeling. The visual effect is more beautiful, more durable and environmentally friendly. The first assembled floor and the second assembled floor are clamped and fixed by the interference fit of the concave clamping groove and the wedge-shaped clamping strip. The fixing method is simple and effective, and not easy to loosen. The floor body can achieve surface wear resistance through the wear-resistant layer set.

[0004] The chamfered color film of the above application may shrink and rebound during the molding and chamfering, resulting in color distortion of the chamfered color film, thereby affecting the aesthetics of the floor. In addition, it only relies on the interference fit of the recessed slots and the wedge-shaped slots to fix the first assembled floor and the second assembled floor, which makes it easy for the two to move due to external impact or vibration after splicing, increasing the probability of gaps and affecting the splicing effect. To address the above problems, we have launched a PVC floor that can be molded and chamfered online. Utility Model Content

[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application usually described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0018] The utility model discloses a PVC floor capable of online molding chamfering, which is mainly used in scenarios where the chamfered color film may shrink and rebound during molding chamfering, and the floor may be easily displaced due to external impact or vibration after being assembled.

[0019] Reference Figure 1-Figure 3 A PVC floor with online molded chamfers comprises: a first assembled floor 1, a second assembled floor 2 is movably connected to the right side of the first assembled floor 1, the tops of the first assembled floor 1 and the second assembled floor 2 are both provided with arc chamfers, a threaded rod 3 is fixedly connected to the bottom end of the second assembled floor 2, a containing groove 4 is provided in the first assembled floor 1, a threaded cylinder 5 is rotatably connected in the containing groove 4, a rotating hole 6 is provided at the front end of the first assembled floor 1, an installation slide groove 9 is provided at the bottom end of the first assembled floor 1 and the bottom end of the second assembled floor 2, a bearing plate 10 is slidably connected in the installation slide groove 9, an SPC substrate 11 is provided in the first assembled floor 1 and the second assembled floor 2, a positioning layer 13 is provided above the SPC substrate 11, a decorative layer 14 is provided on the top of the positioning layer 13, and a wear-resistant layer 15 is provided on the top of the decorative layer 14.

[0020] In this embodiment, the first assembled floor 1 and the second assembled floor 2 are assembled together, and then the two are slid so that the installation groove 9 at the bottom can completely slide into the top of the supporting plate 10, and then the finger or tool is inserted into the rotating hole 6 and the threaded cylinder 5 is rotated to rotate it in the containing groove 4. As the threaded cylinder 5 rotates, the threaded rod 3 will move toward the bottom of the threaded cylinder 5 until the threaded rod 3 completely enters the threaded cylinder 5. The U-shaped supporting plate 10 can limit the first assembled floor 1 and the second assembled floor 2 assembled together to prevent the floor from being displaced due to external collision or vibration, and effectively reduce the gap between the floors to reduce the probability of water or small foreign matter falling into the bottom of the floor. The decorative layer 14 adopts a polymer PVC film, which has excellent ductility and can perfectly wrap The decorative layer 14 is durable due to its stable molecular structure, and has a very good inhibitory effect on corrosion caused by changes in temperature, oil, dust, mud and the like. The positioning layer 13 is made of PET film. Since the PET film is strong and tear-resistant, it is very suitable for applications requiring high tensile strength and dimensional stability, so that the decorative layer 14 can be supported and positioned during molded chamfering to prevent the decorative layer 14 from color distortion due to shrinkage and rebound, thereby effectively ensuring the aesthetics of the floor. At the same time, the PET film also has good gas and moisture barrier properties, which is beneficial to improving the sealing and waterproof properties of the floor. The wear-resistant layer 15 can increase the anti-fouling and wear-resistant effect of the surface of the floor during use, thereby reducing the probability of damage to the floor caused by trampling or friction with objects.

[0021] In the above scheme, it is considered that the threaded barrel 5 is round and easy to slip when sliding on it. The threaded barrel 5 will be displaced during the rotation process due to the lack of a limiting structure, thereby affecting the assembly effect. If the receiving groove 4 and the limiting groove 7 are too small, the threaded barrel 5 and the limiting rod 8 will rub against the receiving groove 4 and the limiting groove 7 respectively during the rotation process, thereby causing wear to the threaded barrel 5. If the size of the bearing plate 10 is not suitable, it will not be tight enough after being assembled with the first assembled floor 1 and the second assembled floor 2, thereby affecting the assembly effect. The floor is easy to be ignited during actual use, thereby posing a greater safety hazard. The specific operation is as follows:

[0022] Reference Figure 3 In a preferred embodiment, a non-slip sleeve is provided on the surface of the threaded barrel 5, a sealant is filled between the first assembled floor 1 and the second assembled floor 2, a limiting groove 7 is provided below the containing groove 4 in the first assembled floor 1, a limiting rod 8 is provided in the limiting groove 7, a bottom end of the threaded barrel 5 and a top end of the limiting rod 8 are fixedly connected, the size of the containing groove 4 is larger than the size of the threaded barrel 5, the size of the limiting groove 7 is larger than the size of the limiting rod 8, the bearing plate 10 is U-shaped, the width of the bearing plate 10 is equal to the sum of the widths of the two mounting slide grooves 9, and a graphite flame retardant layer 12 is provided between the SPC substrate 11 and the positioning layer 13;

[0023] In this embodiment, by arranging an anti-skid sleeve on the surface of the threaded barrel 5, the friction between the threaded barrel 5 and the hand or tool can be increased, thereby preventing slipping during the rotation of the threaded barrel 5; by arranging the limiting groove 7 and the limiting rod 8, the threaded barrel 5 can be limited, thereby preventing the threaded barrel 5 from being displaced during the rotation, effectively ensuring the splicing effect; the size of the containing groove 4 is larger than the size of the threaded barrel 5; the size of the limiting groove 7 is larger than the size of the limiting rod 8, thereby reducing the wear on the threaded barrel 5; the bearing plate 10 is U-shaped and its width is equal to the sum of the widths of the two installation grooves 9, so that it can limit the first assembled floor 1 and the second assembled floor 2 spliced ​​together in the horizontal direction, thereby further improving the tightness of the connection between the first assembled floor 1 and the second assembled floor 2; by filling the sealant between the first assembled floor 1 and the second assembled floor 2, the probability of water or tiny foreign matter penetrating from the gap between the first assembled floor 1 and the second assembled floor 2 can be further reduced; by arranging the graphite flame retardant layer 12, the fire resistance of the floor can be effectively improved, thereby helping to improve the safety of the floor.

[0024] The above are only preferred specific implementations of the utility model, but the protection scope of the utility model is not limited to them. The replacement can be a replacement of part of the structure, device, method steps, or a complete technical solution. Equivalent replacement or changes based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
