s4, cooling; cooling the section blank manufactured in the step S3 by a constant-temperature water tank; when the water temperature is 25-30 ℃, if the water temperature is too low, the cooling is too fast, internal stress is easy to exist, and if the water temperature is too high, the cooling is slow, and the efficiency is low;
s5, embossing; embossing the section manufactured in the step (4) by using a steel embossing die;
uniformly heating the steel mould to 60-70 ℃ before embossing the steel mould, and then embossing, wherein the pressed patterns are clear and labor-saving; if the heating is not carried out, the surface of the section bar is easy to damage;
s6, thermally transferring and pasting a film; heating the thermal transfer printing film at one time, and transferring the decorative pattern on the thermal transfer printing onto the surface of the section bar manufactured in the step S5 to form a decorative film;
the thermal transfer printing decoration process is a process of transferring the decoration pattern on the thermal transfer printing to the surface of the decorated building material through one-time heating of the thermal transfer printing film to form a high-quality decoration film. In the process of thermal transfer printing, the protective layer and the pattern layer are separated from the polyester substrate by utilizing the combined action of heat and pressure, and the whole decorative layer and the section bar are permanently glued by the hot melt adhesive.
The heat transfer film is made of polyethylene film as lining paper and printed with wood grain decoration layer. The surface is coated with a protective layer, a bottom color layer, a stripping layer and a hot melt adhesive layer.
The high-temperature silicon roller is heated, the temperature and the pressure are applied to the transfer foil, so that a transfer printing layer consisting of the decorative wood grain printing layer, the surface protection layer and the ground color layer is separated from polyethylene and is transferred to the surface of an artificial board or a furniture part, and a decorative surface pattern is formed, and the surface of the profile has excellent performances of wear resistance, heat resistance, light resistance and the like, and is novel and attractive in pattern and stable in color tone;

s8, forming an outer frame; manufacturing the section bar in the step S7 into an irregular mirror frame shape in a mould in a constant temperature mode; the heating temperature is 70-80 ℃, and the performance of the colorant can be influenced by overhigh temperature, so that the mirror frame is discolored; if the deformation is too low, the deformation is difficult, and the spectacle frame is cracked unrecoverable;
s9, cooling the outer frame; completely cooling and shaping the irregular mirror frame in the step S8 through an air cooling pipe with the air outlet pressure of 0.65 Mpa;
s10, cutting an outer frame; cutting the opening of the irregular mirror frame in the step S9 into a splicing angle by using a V-shaped corner cutting machine; the angle is 45 degrees; the two edges are combined together to form 90 degrees, so that the appearance is attractive and elegant;
s11, outer frame nail angles; splicing the irregular mirror frames in the step S10 together by using a numerical control corner nailing machine according to a proper corner seam and nail holding force process;
s12, assembling the lens; placing the irregular lens frame obtained in the step S11 on a production line, installing the cut lens, and fixing the joint of the periphery of the lens and the irregular outer frame by using hot melt adhesive;
s13, packaging; and (3) wrapping six surfaces of the mirror product obtained in the step (12) by using a baolilong buffer material, and completely packaging by using a five-layer corrugated board box.
Through the processes of material mixing and granulation, various components of the special-shaped picture frame formula can be uniformly mixed, and the phenomenon that the weak part of the picture frame is broken due to nonuniform mixing is avoided;
and S9, cooling the outer frame by adopting a reciprocating mode through the air cooling pipe adopted by the cooling of the mirror frame. The cooling speed is high; the cooling is uniform. The lens frame is not deformed due to uneven cooling.
Example 2
This embodiment is different from embodiment 1 in that,
the stabilizer adopts organic antimony with stable color and luster and lower melt viscosity; the beneficial effects and the disadvantages of adopting organic antimony are that,
(1) The stability is better, and the organic antimony stabilizer has a particularly prominent effect when used together with calcium stearate in a double-screw extrusion process at the same temperature.
(2) The price is lower, and the organic antimony stabilizer is much lower than that of methyl tin or butyl tin. In addition, the amount of organic antimony used is low, and therefore a better performance/price balance can be achieved with organic antimony.
(3) The product is non-toxic and in the United states, PVC risers made using formulations of antimony based stabilizers and calcium stearate and other lubricants meet the United states NSF (National dilution Foundation) regulations when PVC pipe is made using a twin screw extruder.
(4) The transparency and light stability are poor, the transparency of the organic antimony compound is not as good as that of an organic tin stabilizer, the organic antimony compound is lower than that of a barium/Fu and calcium/zinc metal soap system, the organic antimony compound is close to that of lead salts, and the light stability is poor, so that the antimony stabilizer is frequently used for indoor products without color requirements. Antimony stabilizers themselves also require storage in opaque containers.
(5) The antimony-based stabilizer has poor lubricity and therefore, a large amount of lubricant is added without exception.
The product is nontoxic and cheap, so the organic antimony stabilizer is adopted.
