Embodiment 1

[0026] A drying method for water transfer printing of plastic products, comprising the following steps:

[0027] A. Take out the water-transferred plastic product from the sink, and dry the water stain on the surface of the plastic product with an air gun;

[0028] B. Then use a hot air blower to blow hot air on the surface of the plastic product;

[0029] C. Then put the plastic product into the oven for baking.

[0030] Wherein, in the step B, the air outlet temperature of the hot air blower is 85°C, and the wind speed is 12m / s, so that the surface temperature of the plastic product reaches 30°C.

[0031] In the step C, the temperature of the oven is 75°C, and the baking time is 10 minutes, so that the temperature of the surface of the plastic product reaches 50°C.

[0032] In the step B, the blowing head of the hot air blower is fixed on the manipulator, and one manipulator is equipped with a blowing head, and the manipulator is a four-axis linkage manipulator...

Abstract

The invention relates to the technical field of hydrographic transfer printing, in particular to a plastic product hydrographic transfer printing drying method. The plastic product hydrographic transfer printing drying method includes the following steps: A, plastic products obtained after hydrographic transfer printing are taken out from a water tank, and water spots on the surfaces of the plastic products are blown to be dry through an air-pressure air gun; B, hot air is blown to the surfaces of the plastic products with a hot air machine; C, the plastic products are placed into an oven for baking. By means of the drying method, after the plastic products obtained after hydrographic transfer printing are dried through the hot air machine, the plastic products are placed into the oven for baking, as the plastic products have been dried one time through the hot air machine before being placed into the oven, the plastic products only need to be baked for 4 min to 10 min in the oven, and the reject ratio of the plastic products can be reduced while the time is saved. By means of the drying method, the baking time is shortened, and the production efficiency is improved; in addition, the reject ratio caused by baking deformation is reduced, and the good social benefit and the good social benefit are achieved.

Description

technical field [0001] The invention relates to the technical field of water transfer printing, in particular to a drying method for water transfer printing of plastic products. Background technique [0002] Three-dimensional coating water transfer printing technology uses three-dimensional coating water transfer printing film to transfer patterns to various materials, for example, plastics (such as acrylonitrile-butadiene-styrene fiber, polymethyl polyaniline, polyvinyl chloride , polyurethane, polymethyl methacrylate), rubber, wood, metal, glass, nylon and ceramics. The three-dimensional coating water transfer film generally includes a pattern layer and a carrier layer, the pattern layer is an ink layer, and the carrier layer is a water-based film such as a polyvinyl alcohol (PVA) film. The three-dimensional coating water transfer printing method generally includes laying the pattern layer of the three-dimensional coating water transfer film upward on the water surface, ...
