Claim 0:
1. A production method of a floor for quick side-slide installation, comprising the following steps:
step 1: sorting of floor blanks:
the floor blanks are inspected one by one in terms of moisture content, dimensions and appearance quality; the moisture content is controlled within 6-11%; the dimensions are predetermined; and the appearance quality meets a requirement of LY/T 2058-2012 Blanks for Solid Wood Flooring;
step 2: curing of the floor blanks:
the floor blanks after being sorted in step 1 are stacked in a curing area for a curing, wherein a duration of the curing is 25-30 days; the floor blanks are ventilated and protected from sun and rain, and the curing area has a relative humidity of 25-55% and a temperature of 20-25° C.;
step 3: sanding of the floor blanks:
top surfaces of the floor blanks after being cured in step 2 are sanded to be flat and smooth;
step 4: cutting-to-thickness of the floor blanks:
the floor blanks after being sanded in step 3 are put on a conveyor belt, and respective back surfaces of the floor blanks face up when the floor blanks are fed by the conveyor belt to enter a planer; a back-groove-free tool is used to cut the floor blanks to a predetermined thickness; and after cutting-to-thickness, the back surfaces of the floor blanks are flat and smooth without indentation;
step 5: surface treatment of the floor blanks:
the top surfaces of the floor blanks are treated to be flat or non-flat; wherein
when the top surfaces of the floor blanks are required to be non-flat, the top surfaces of the floor blanks are hand-scraped or wire-brushed; and
when the top surfaces of the floor blanks are required to be flat, the top surfaces of the floor blanks need no treatment;

step 6: cutting-to-length and molding of the floor blanks:
the floor blanks after being surface-treated in step 5 are placed on a four-sided planer; first, a double-end milling device is used to cut the floor blanks to a predetermined length; a pre-cutting knife, a molding knife, a finishing knife and a locking knife of the four-sided planer are activated in sequence to mill two layers of fixing grooves at a periphery of the floor blanks, wherein upper fixing grooves and lower fixing grooves are retracted from the top surfaces to the back surfaces of the floor blanks; a boss with an inclined side is formed between a top surface of each of the upper fixing grooves and a top surface of each of the floor blanks; and an acute angle is defined between the inclined side and a top surface of a first groove;
step 7: spraying of anti-cracking oil on the floor blanks:
the anti-cracking oil is evenly sprayed by a spray gun onto peripheral end surfaces of the floor blanks after being milled in step 6;
step 8: plastic encapsulation of the floor blanks:
the floor blanks after being sprayed with the anti-cracking oil in step 7 are placed in a lower molding cavity of a lower mold, wherein the top surfaces of the floor blanks face down; an upper mold is closed downward with the lower mold; then an injection head injects a molten material into locking cavities formed by the periphery of the floor blanks and an upper molding cavity of the upper mold and the lower molding cavity of the lower mold; after injection, water is immediately pumped to cool the lower molding cavity of the lower mold; an injection-molded frame and injection-molded locks formed on the injection-molded frame are formed at the periphery of the floor blanks; and the injection-molded frame is hidden under bosses of the floor blanks;
step 9: application of a paint to the back surfaces of the floor blanks:
the back surfaces of the floor blanks after being subjected to plastic-encapsulation in step 8 are sanded by a sander, and are applied with the paint; and
step 10: application of the paint or vegetable oil to the floor blanks:
the floor blanks after being applied with the paint on the back surfaces in step 9 are sanded by the sander, and then are applied with the paint or the vegetable oil.
