A manufacturing method of a switch socket packaging box comprises the following steps:
s100, pulping, namely mixing the materials to form slurry with the concentration of 0.8%, and stirring for 30-40 min;
s200, vacuumizing, sucking the pulp into a vacuum mould, and vacuumizing the vacuum mould to dehydrate the pulp to form a fiber blank;
s300, heating, keeping the vacuum mold in a vacuumizing state, setting the temperature in the vacuum mold at an active temperature for fiber entanglement, and maintaining for 35S to enable the water content of the fiber blank to be not higher than 70%;

Example 4
The manufacturing method of the switch socket packaging box is the same as that of embodiment 3, except that the following steps are added in step 2:
2.1, ultrasonic processing is carried out on the slurry entering the vacuum mould by using ultrasonic equipment while the slurry is sucked, wherein the ultrasonic power is 1KW, and the ultrasonic processing time is 15 s;
2.2 adding a sterilizing agent into the slurry in the ultrasonic treatment process, wherein the sterilizing agent is a hydrogen peroxide silver ion disinfectant.
Ultrasonic treatment can let the thick liquid get into the vacuum mold when the various spacing even orderly of containing arrange, and convenient subsequent fibre is intertwined, promotes product quality, can let the antiseptic agent sneak into the thick liquid fast simultaneously in, suppresses the infection in the packing carton manufacture process.
Example 5
The manufacturing method of the switch socket packaging box is the same as that of the embodiment 3, except that the step 4 is added with the following steps:
3.1 spraying atomized water on the surface of the fiber blank to increase the water content of the surface of the fiber blank to 20 percent.
Can promote the moisture content on fiber body surface, soften the surface of fiber body, make the fiber body can become when carrying out the hot pressing more smooth, promote the aesthetic measure of packing carton, the water loss amount when can also reserving the hot pressing avoids the surface of fiber body to lead to the coking when the hot pressing because of losing water too much and is crisp or even fracture, can also stabilize the pyrocondensation volume of fiber body, promotes the yields.
Example 6
The manufacturing method of the switch socket packaging box is the same as that of embodiment 3, except that the step 5 is added with the following steps:
5.1, hot pressing for 5 seconds at the set temperature of 150 ℃;
5.2, carrying out secondary hot pressing, wherein the set temperature is 120 ℃, the duration is 4s, and the whole packaging box is reduced by 0.5 mm;
hot pressing for 5.3 times, setting the temperature to be 100 ℃, keeping for 3s, and reducing the whole packaging box by 0.3 mm.
Utilize the hot pressing of the different temperatures of cubic, the hot pressing reduces the moisture content on packing carton surface for the first time, and smooth its surface, the hot pressing of second time can make the packing carton take place the pyrocondensation, make its whole shrink 0.5mm, the hot pressing of third time can make the packing carton take place the pyrocondensation again, make its whole shrink 0.3mm, make the surface of fibre body more smooth and flat paste smoothly through the aforesaid operation, the size is more evenly stable, reduce the product tolerance, during the hot pressing for the first time, the moisture content in the fibre body is higher, therefore need higher temperature, then progressively reduce the temperature, it is stable to carry out the hot pressing shrink to the fibre body, if only carry out hot pressing once, set up the temperature at 100 ℃, the time that hot pressing needs is longer, can cause the destruction to the fibre, influence the structural strength of packing carton.
