Plastic floorboard processing technology using digital printing

1. A method for processing plastic floorboards using digital printing, comprising:

preparing a base material, wherein the base material comprises PVC, stone powder, a stabilizer, stearic acid, PE wax and a modifier;

blending the base material at a temperature of 120° C. at a speed of 2000 r/min, and blending the base material at a speed of 200 r/min when the temperature falls to 50° C.;

extruding the blended base material into a mold through a twin-screw extruder to form a stone-plastic base material;

adjusting a gap between a surface embossing roll and a bottom embossing roll to enable the stone-plastic base material to pass through the gap, wherein the surface embossing roll has a first thickness and the bottom embossing roll has a second thickness, wherein a marking block is carved on an edge of the surface embossing roll;

generating embossing patterns and positioning marks at equal intervals on a surface of the stone-plastic base material, wherein generating embossing patterns and positioning marks comprises passing the stone-plastic base material through the gap;

cooling the stone-plastic base material at a natural temperature between 26° C.-30° C.;

selecting a first positioning mark of the positioning marks as a first point and a second positioning mark of the positioning marks as a second point, wherein the second positioning mark is selected according to a required length of the plastic floorboard;

cutting the stone-plastic base material into plastic floorboards with the required length, wherein cutting the stone-plastic base material comprises cutting the stone-plastic base material at the second point;

using a digital printer to print the plastic floorboards, wherein the digital printer starts printing when the first point is sensed by a sensing device of the digital printer, and stops printing when the second point is sensed;

shower-coating a UV primer paint and a UV finish paint on the plastic floorboards;

reconditioning the plastic floorboards; and

slotting the plastic floorboards.

2. The method for processing plastic floorboards using digital printing of claim 1 , wherein generating embossing patterns and positioning marks comprises introducing heat conduction oil into the surface embossing roll to heat the surface embossing roll to a temperature between 180-190° C.

3. The method for processing plastic floorboards using digital printing of claim 1 , wherein using the digital printer to print the plastic floorboards comprises preparing patterns to be digitally printed according to the embossing patterns, and spray-printing the patterns on surfaces of plastic floorboards.

4. The method for processing plastic floorboards using digital printing of claim 3 , wherein the marking block is carved at a starting end of the embossing patterns on the surface embossing roll.

5. The method for processing plastic floorboards using digital printing of claim 1 , further comprises forming jointing slots in side edges of the plastic floorboards.

6. The method for processing plastic floorboards using digital printing of claim 1 , wherein shower-coating a UV primer paint and a UV finish paint on the plastic floorboards comprises placing the floorboards in an environment having 50% humidity.
