Aluminum profile double-fan vacuum wooden transfer furnace

Abstract

The invention provides an aluminum profile double-fan vacuum wooden transfer furnace which is simple and compact in structure, fast in temperature rise in a furnace body, good in constant temperature effect and stable and reliable in transfer quality. The aluminum profile double-fan vacuum wooden transfer furnace comprises the wooden transfer furnace body, a pair of furnace doors, a pair of driving devices, a combustion container, a combustor, a pair of circulation blowing components, a pair of vacuum transfer systems, a left feeding trolley, a right feeding trolley and an operation control panel. The furnace doors are located at the two ends of the wooden transfer furnace body. The driving devices are used for driving the furnace doors to be closed and opened respectively. The combustion container is arranged at the top end of the wooden transfer furnace body. The combustor is arranged at the top end of the wooden transfer furnace body and used for providing heat for the combustion container. The circulation blowing components are connected to the two sides of the combustion container respectively and used for providing hot air for aluminum profiles in an inner cavity of the wooden transfer furnace body. The vacuum transfer systems are located on the two sides of the wooden transfer furnace body. The left feeding trolley and the right feeding trolley are used for being connected with the vacuum transfer systems respectively and the wooden transfer furnace body. According to the technical scheme, the aluminum profiles in the wooden transfer furnace are heated more evenly, and the constant temperature effect is more excellent, so that the transfer grain of the aluminum profiles is clearer, and the stereoscopic impression is stronger.

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
