Problems solved by technology

[0003] In order to increase the festive atmosphere of Christmas, many Christmas handicrafts will be flocked to simulate the shape of snowflakes. At present, in the Christmas handicraft industry, most of the Christmas handicrafts are flocked with traditional cotton short fiber powder + water-based adhesive, but the traditional flocking The velvet method has the following disadvantages: ①The water-based adhesive used in the traditional flocking process is slow to dry. At the same time, most of the Christmas craft products contain parts made of PVC materials, such as leaves made of PVC. The general drying temperature does not exceed 50°C. Otherwise, the leaves will be curled and deformed. At this drying temperature, the drying speed of the water-based adhesive will be slower, resulting in a long curing operation time and low production efficiency; Low strength, large creep, and easy to corrode the metal brackets of Christmas crafts. Therefore, the service life of snowflake-shaped Christmas crafts produced by traditional flocking technology is short, especially not suitable for outdoor use; ③ traditional flocking technology generally uses Electric heating or other fuel burning and drying methods have high energy consumption, low thermal efficiency, and are not environmentally friendly; ④The waste powder generated is difficult to collect; The waste powder diffused in the air is easily inhaled by the human body, which has a certain impact on human health

Embodiment approach

[0060]In one embodiment, the short fiber powder can be prepared by including at least one of vegetable short fiber, animal short fiber, chemical short fiber, etc.; the vegetable short fiber can include cotton short fiber, kapok short fiber, At least one of flax short fiber, ramie short fiber, sisal short fiber, abaca short fiber, etc.; the animal short fiber may include at least one of wool short fiber, rabbit hair short fiber, and mohair short fiber; The chemical short fibers may include at least one of polyester short fibers, nylon short fibers and the like. It should be noted that when the final effect of flocking is a snowflake shape, if the short fiber powder material itself is not white, the short fiber material should be bleached to make the appearance of the snowflake shape more realistic. Further, the short fiber Powder can be dyed to suit shapes other than snowflakes. Preferably, the short fiber powder is cotton short fiber powder, which is low in cost and easy to obtain, ...

Embodiment 1

[0088](1) Mix and dissolve 60 parts by mass of TMPTA and 4 parts by mass of photoinitiator 1173, then add 35 parts by mass of acrylic resin, 0.5 parts by mass of hydroquinone and 0.5 parts by mass of silicone, and stir at a stirring speed of 300r / min 0.5h, get UV curing adhesive;

[0089](2) Move the Christmas crafts into the flocking device through the conveyor, control the rotation speed of the Christmas crafts to 5r / min, and control the distance between each spray gun and the surface of the Christmas crafts to be 15cm~60cm, and the spray guns are moving back and forth on the slide rail. Spray UV curing adhesive and short cotton fiber on the Christmas crafts. The mass ratio of UV curing adhesive and short cotton fiber is 3:1 per minute, until the Christmas crafts evenly cover the snowflakes, and the spraying operation is completed;

[0090](3) Move the Christmas crafts into the UV curing device through the conveyor, and control the rotation speed of the Christmas crafts to 5r / min. Under...

Embodiment 2

[0093](1) Mix and dissolve 40 parts by mass of TPGTA and 0.5 parts by mass of photoinitiator 184, and then add 59 parts by mass of epoxy acrylate, 0.1 parts by mass of DEHP, 0.2 parts by mass of p-benzoquinone and 0.2 parts by mass of silicone, at 600r / Stir for 1 hour at a stirring speed of min to obtain a UV curable adhesive;

[0094](2) Move the Christmas crafts into the flocking device through the conveyor, control the rotation speed of the Christmas crafts to 5r / min, and control the distance between the spray guns and the surface of the Christmas crafts to be 15cm~60cm. The spray guns will move back and forth on the slide UV curing adhesive and short cotton fiber are sprayed on Christmas handicrafts. The mass ratio of UV curing adhesive and short cotton fiber is 1:1 per minute, until the Christmas handicrafts are evenly covered with snowflakes and the spraying operation is completed;

Abstract

The invention belongs to the field of Christmas handicraft manufacturing, and discloses a novel UV photocuring flocking process for Christmas handicrafts. The flocking process comprises the followingsteps that short fiber powder and a UV curing adhesive are mixed and sprayed on Christmas handicrafts through flocking operation, and then UV curing operation is performed to complete the flocking process. According to the technical scheme, the process production time and energy consumption of Christmas handicraft flocking can be remarkably reduced, and the service life of Christmas handicrafts isprolonged. The invention further provides novel UV photocuring flocking equipment for the Christmas handicrafts. According to the flocking equipment, the automatic UV photocuring flocking process canbe achieved, the flocking efficiency and the yield are improved, the health problem caused by the fact that a human body inhales waste powder in air is avoided, meanwhile, the waste powder generatedin the flocking operation process can be recycled, and further treatment of the waste powder is facilitated.

Description

Technical field[0001]The invention relates to the manufacturing field of Christmas crafts, in particular to a novel UV light curing flocking process and flocking equipment for Christmas crafts.Background technique[0002]With the development of economic globalization and cultural diversification, Christmas has gradually developed from a religious holiday into a global holiday. Decorating houses with Christmas crafts is a traditional way to celebrate Christmas. At the same time, with the globalization of Christmas culture, the annual consumption of Christmas crafts continues to increase. Among them, 96% of the world's Christmas crafts are made in China.[0003]In order to increase the Christmas atmosphere, many Christmas crafts will be flocked to simulate the shape of snowflakes. At present, in the Christmas crafts industry, most of the Christmas crafts are flocked with traditional cotton short fiber powder + water-based adhesive. The flocking method has the following shortcomings: ①The ...
