Problems solved by technology

However, most of the existing wood-plastic panels contain wood powder, and there are many hidden dangers in the process of transportation, storage and maintenance of wood powder, such as relatively easy to be affected by moisture, fire, and even formaldehyde pollution; The time is not stable enough, it is easy to appear the phenomenon of difficulty in blanking and mold paste
In addition, other boards also have problems such as poor performance and difficult processing.
[0004] For wood-plastic flooring, some of its edges are straight-faced without chamfers. This kind of floor can be assembled seamlessly, but after the floor is assembled, the three-dimensional effect is not strong, and it is not beautiful enough.
The edge of another type of floor is arc chamfered or beveled. Although this kind of floor has achieved an aesthetic effect, after the floor is paved, adjacent floors are prone to wear, height differences, and Disadvantages of stitching, easy deformation and warping

Embodiment 1

[0058] A molding device for preparing PVC block molded flooring, including a fixed template 1 and a movable template 2 facing up and down, and an upper module 3 and knives symmetrically distributed on both sides of the upper module 3 are fixedly connected to the lower part of the fixed template 1 4. The first blade 7 on the cutter 4 close to the upper module 3 is an arc-shaped blade for cutting the side of the floor to form a circular arc chamfer; the upper part of the movable template 2 is fixedly connected with the lower module 5, the A discharge block 6 is provided between the lower module 5 and the upper module 3; the plate to be molded is placed in the discharge block 6, and the hot pressing is realized through the upper module 3 and the lower module 5, and the cutter 4 cuts the plate to form PVC block molded flooring. The second cutting edge 8 on the cutter 4 away from the upper module 3 is a beveled cutting edge, and the included angle between the second cutting edge 8 ...

Embodiment 2

[0066] The embossing device is the same as in Embodiment 1, except that at least one double-edged cutter 9 is provided under the fixed template 1 between the two-side cutters 4, and the double-edged cutter 9 has two blades for the floor. Side cutting with a curved edge that forms a rounded chamfer. The cutting tool and the double-edged cutting tool of the present invention are provided with a heating device for heating the cutting tool, the heating temperature is 100°C, and the heating time is 8s.

[0067] Hot pressing:

[0068] (1) Prepare materials: prepare the negative film, color film and wear-resistant layer to be pressed;

[0069] (2) Stacking: When stacking, each layer of material is placed in the middle of the tray and the layers are aligned, no stacking, no stacking, no foreign matter mixed in, no wrinkling of the color film;

[0070] (3) Push into the molding device for hot pressing. The hot pressing temperature is 140°C, the time is 18 minutes, and the pressure is...

Embodiment 3

[0073] The molding device is the same as that in Example 1, except that: the tool of the present invention is provided with a heating device for heating the tool, the heating temperature is 90° C., and the heating time is 6 s.

[0074] Hot pressing:

[0075] (1) Prepare materials: prepare the negative film, color film and wear-resistant layer to be pressed;

[0076] (2) Stacking: When stacking, each layer of material is placed in the middle of the tray and the layers are aligned, no stacking, no stacking, no foreign matter mixed in, no wrinkling of the color film;

[0077] (3) Push into the molding device and carry out hot pressing. The hot pressing temperature is 130°C, the time is 16min, and the pressure is 6mpa; during the hot pressing process, a heating device is set on the knife and / or double-edged knife to heat the knife, and the knife cuts the floor to form a single block And / or multiple floors with curved chamfers, keep the heat and pressure on the floor for 15s at th...

Abstract

The invention discloses a mold pressing device for preparing a PVC blocky mold-pressed floor board. The mold pressing device comprises a fixed mold plate and a movable mold plate, and the fixed mold plate and the movable mold plate are oppositely arranged in the vertical direction. The lower portion of the fixed mold plate is connected with an upper mold block and cutters which are symmetrically distributed on the two sides of the upper mold block. First blades are arranged on the sides, close to the upper mold block, of the cutters, and the first blades are arc-shaped blades which are used for forming arc-shaped chamfers on one side of the floor board through cutting. The upper portion of the movable mold plate is connected with a lower mold block. A discharging block is arranged between the lower mold block and the upper mold block. When a board to be subjected to mold pressing is placed in the discharging block, the board is cut by the cutters to form the PVC blocky mold-pressed floor board while hot pressing is achieved through the upper mold block and the lower mold block. According to the mold pressing device, the cutters are additionally arranged on the two sides of the upper mold block, the side edge of the floor board is cut to form the chamfers in the hot pressing process, the internal structure of a floor board base material is prevented from being damaged, and the stability of the whole floor board is good; and the flatness of the cut surface is guaranteed through machining equipment, and the phenomenon that the surface of the floor board is uneven is avoided.

Description

technical field [0001] The invention relates to a device for preparing boards and a preparation method thereof, in particular to a molding device for preparing PVC block molded floors and a preparation method thereof. Background technique [0002] Plates are widely used in household manufacturing, construction and processing industries due to their excellent characteristics such as wide sources, various types, and easy processing. According to the molding structure, the panels can be roughly divided into solid wood panels, plywood, wood-plastic panels, plywood and decorative panels. [0003] However, there are many problems in the existing boards, such as wood-plastic board, which is a new type of composite material integrating the advantages of wood and plastics, wherein "wood" is selected from waste wood, wood powder, wood fiber, sawdust, etc. Or straw, etc., "plastic" can be polyethylene, polypropylene, polystyrene, polyvinyl chloride and other polymers, supplemented wit...
