Wood grain transfer printing furnace for aluminum material surface treatment

Abstract

The invention provides an aluminum profile double-draught-fan vacuum wood grain transfer printing furnace which is simple and compact in structure, rapid in heating in a furnace body, good in a constant-temperature effect and stable and reliable in transfer printing quality. The aluminum profile double-draught-fan vacuum wood grain transfer printing furnace comprises a wood grain transfer printingfurnace body, a pair of furnace doors located in the two ends of the wood grain transfer printing furnace body, a pair of drive devices for driving the pair of furnace doors to be closed and opened,a combustion inner container arranged at the top end of the wood grain transfer printing furnace body, a combustor used for providing heat for the combustion inner container, a pair of circulating blowing assemblies connected to the two sides of the combustion inner container and used for providing hot air for an aluminum profile in the wood grain transfer printing furnace body, a pair of vacuum transfer printing systems located on the two sides of the wood grain transfer printing furnace body, a left feeding trolley, a right feeding trolley and an operation control panel, wherein the left feeding trolley and the right feeding trolley are used for connecting the pair of vacuum transfer printing systems and the wood grain transfer printing furnace body. According to the scheme, the aluminumprofile in the wood grain transfer printing furnace is more evenly heated, the constant-temperature effect is also more excellent, then transfer printing grain of the aluminum profile is clearer, andthe stereoscopic sense is higher.

Description

technical field [0001] The invention relates to the technical field of aluminum profile surface treatment and processing equipment, in particular to a double-fan vacuum wood grain transfer furnace for aluminum profiles. Background technique [0002] As aluminum profiles are more and more widely used in people's daily life, in order to better meet people's aesthetic requirements, most of the aluminum profiles used in construction have wood grain textures on their surfaces. Existing methods for adding texture to aluminum profiles include the method of directly pressing the texture on the surface of the profile while the profile is being extruded. When this type of method is used, the manufacturing cost is very high and the technical difficulty is too large; the other is Texture is applied to the surface of the aluminum profile by means of electrostatic spraying. The principle is to coat a layer of thermosetting organic polymer powder on the surface of the aluminum profile and ...

Existing methods for adding texture to aluminum profiles include the method of directly pressing the texture on the surface of the profile while the profile is being extruded. When this type of method is used, the manufacturing cost is very high and the technical difficulty is too large; the other is Texture is applied to the surface of the aluminum profile by means of electrostatic spraying. The principle is to coat a layer of thermosetting organic polymer powder on the surface of the aluminum profile and cure at a high temperature to form a coating with certain permeability on the surface of the profile. The coating is covered with ink paper printed with wood grain patterns, and after high temperature, using the principle of molecular diffusion, the ink layer penetrates into the coating to form a profile that imitates wood grain colors. When this method is used, it is limited by the process. , the thickness of the coating on the surface of the profile is uneven, coupled with the weakness of the thermosetting organic polymer material itself, its products have the disadvantages of easy powdering, fading and poor weather resistance of the coating.

For this reason, the existing aluminum profiles generally achieve the imitation effect by adopting the method of wood grain transfer printing, but because of the wood grain transfer printing furnace, it generally only adopts a single high-power fan and a single pipeline that enters from the left and exits from the right. Circulation system, the furnace body in the wood grain transfer furnace heats up slowly during the working process, the production capacity is low and the energy consumption is large, which is not conducive to the reduction of production costs and the improvement of production efficiency
