Description

Technical Field

[0001] The utility model relates to the technical field of aluminum profile wood grain transfer printing, in particular to an aluminum profile multi-structure vacuum wood grain transfer printing furnace. Background Art

[0002] As aluminum profiles are increasingly widely used in people's daily lives, in order to better meet people's aesthetic requirements, most of the aluminum profiles used in construction have wood grain textures added to their surfaces. Existing methods for adding textures to aluminum profiles include directly pressing the texture on the profile surface while extruding the profile. When using this type of method, the manufacturing cost is very high and the technical difficulty is relatively large; another method is to apply textures on the surface of the aluminum profile by electrostatic spraying. The principle is to coat a layer of thermosetting organic polymer powder on the surface of the aluminum profile, and after high-temperature curing, a coating with a certain permeability is formed on the surface of the profile, and then the coating is covered with ink paper printed with wood grain colors, and then after high temperature, the molecular diffusion principle is used to make the ink layer penetrate into the coating to form a profile with imitation wood grain color.

[0003] The publication number in the existing public technology is: CN217993817U. A vacuum wood grain transfer device for aluminum profiles includes a workbench and a wood grain transfer furnace body. The upper ends of the upper end surface of the workbench are respectively provided with moving grooves, the middle of the upper end surface of the workbench is provided with a sliding groove, the middle of the inner cavity of the sliding groove is rotatably connected with a threaded rod, the upper end surface of the workbench is installed with a moving device, one side of the workbench is fixedly connected with a track, the upper end surface of the wood grain transfer furnace body is installed with a heating device, and one end of the wood grain transfer furnace body is installed with a sealing device. The utility model relates to the technical field of aluminum profile wood grain transfer. The vacuum wood grain transfer device for aluminum profiles solves the problem that uneven heating leads to poor transfer effect and large loss when the traditional wood grain transfer device for aluminum profiles is used.

[0004] However, the above patent still has certain disadvantages during use: when the aluminum profile is taken out after transfer, the opening of the sealed door will cause the internal heat to overflow, and the temperature of the aluminum profile is also high at this time, and it needs to be cooled later. At this time, these two parts of heat are not effectively utilized, and the overall utilization effect of the waste heat generated during the operation is not very good. In addition, the high-temperature aluminum profile is not convenient for subsequent operations of personnel. The overflowing hot air and high-temperature aluminum profile can easily cause burns to personnel, and the safety of the operation is not ideal. At the same time, during transfer, a group of processing must be completed before subsequent loading and unloading operations can be carried out. The replacement process takes a long time, which reduces the overall operation continuity and efficiency. The use effect of the device is not ideal.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0032] In one embodiment, a heating groove 16 is opened at the bottom surface of the interior of the heating chamber 14, and several groups of electric heating plates 18 are installed inside the heating groove 16. Several groups of air guide holes 19 are opened between the electric heating plates 18 at the bottom of the interior of the heating groove 16, and one end of the air guide hole 19 is connected to the blower 6 through a pipe.

At this time, the operation of the motor 17 can drive the drive shaft 12 to rotate, and thereby drive the heat insulation plate 13 connected thereto. The rotation of the heat insulation plate 13 can push the aluminum profile from the preheating chamber 4 to the heating chamber 14.

Moreover, since the transfer of the entire aluminum profile chamber is realized inside the transfer furnace and the heat will not overflow, the secondary utilization of the heat can be well realized and the high-temperature gas overflow can be avoided to cause burns to personnel. Then, after the aluminum profile in the cooling chamber 9 is cooled, it can be removed from the cooling chamber 9. The preheating chamber 4 and the cooling chamber 9 can be taken out and replaced with a new aluminum profile. At this time, the functions of the preheating chamber 4 and the cooling chamber 9 can be interchanged. The device replaces the functions through the different temperatures inside the cooling chamber 9 and the preheating chamber 4. Subsequent personnel can set an indicator light on the surface of the corresponding chamber. The indicator light is on to facilitate personnel to judge whether to use the preheating chamber 4 or the cooling chamber 9 for loading and unloading operations of new aluminum profiles. This can ensure the continuity of the operation and improve the efficiency of the operation, so that the device can be better used. The device as a whole has the advantages of good waste heat utilization, anti-scalding operation, and high operation continuity.
