DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1-2The utility model is an adjustable double-tray lifting furnace, comprising a furnace body 1, a support frame 2, a box body 3, a conveying mechanism 4 and a lifting mechanism 5. The furnace body 1 is arranged on the support frame 2. The furnace body 1 comprises a shell 101 and a heating assembly 102. A furnace opening is opened on the lower surface of the furnace body 1. The boxes 3 are respectively arranged on both sides of the support frame 2. There are two boxes 3. A protective net 301 is arranged on the side of the box body 3. A cooling fan 302 is arranged above the box body 3. The cooling fan 302 is used to dissipate heat for the box body 3. The conveying mechanism 4 is arranged on the box body 3. The conveying mechanism 4 comprises a conveying rail 401, a support seat 402, a first tray 403 and a second tray 404. The conveying rail 401 is arranged on the support seat 402. A commutator 504 is respectively arranged on both sides of the support seat 402. The commutator 504 cooperates with the lifting mechanism 5 to convey the first tray 403 and the second tray 404 up and down. The first tray 403 and the second tray 404 are respectively arranged at both ends of the conveying rail 401. The first tray 403 and the second tray 404 are arranged in a stacked manner. The upper surfaces of the first tray 403 and the second tray 404 are provided with a material discharging platform, and the setting of the material discharging platform ensures that the material is in the optimal temperature area of ​​the furnace. The first tray 403 and the second tray 404 are respectively provided with a walking mechanism 6 below, and the walking mechanism 6 includes a base 601 and a walking wheel 602. A driving motor 7 is respectively installed below the base 601, and the driving motor 7 drives the walking wheel 602 to move. The conveying rail 401 has two tracks. There are four walking wheels 602, and the walking wheels 602 move on the conveying rail 401; the lifting mechanism 5 includes a lifting motor 501, a lifting rail 502 and a lifting platform 503, the lifting motor 501 is arranged below the support seat 402, and the lifting motor 501 is arranged at a corresponding position directly below the furnace mouth. Lifting rails 502 are arranged on the front and rear sides of the support frame 2, and lifting platforms 503 are respectively arranged on the lifting rails 502. The lifting motor 501 drives the lifting rails 502 to move the lifting platform 503 up and down.

[0020] Furthermore, the arrangement of the first tray 403 and the second tray 404 cooperates with the conveying mechanism 4 and the lifting mechanism 5 so that the first tray 403 delivers the material into the furnace body 1 for firing, and then the second tray 404 is subsequently delivered into the furnace body 1 for firing, thereby achieving uninterrupted production. This solves the problem that a conventional lifting furnace has only one tray and is only suitable for the test of a single furnace product. A large industrial furnace that continuously produces without stopping the furnace is not as good as a small box furnace in maintaining temperature uniformity in the furnace, and is not suitable for continuous production of samples such as some chips.

[0021] Furthermore, the initial positions of the first tray 403 and the second tray 404 are respectively at two ends of the conveying rail 401 .

[0022] The working principle of an adjustable double-tray lifting furnace provided by the utility model is:

[0023] When in use, the first tray 403 first moves to the position above the lifting motor 501, the lifting motor 501 is started, the first tray 403 rises to close the furnace mouth, the material is placed on the second tray 404, the furnace body 1 begins to heat up, and after reaching the specified temperature, the first tray 403 is started with one button, descends and returns horizontally to the starting position, then the second tray 404 is started, translated to the position above the lifting motor 501, and the material is sent to the uniform temperature zone in the furnace body 1. At this time, the material can be placed on the first tray 403 for preparation, thus achieving non-stop production.

[0024] The utility model provides an adjustable double-tray lifting furnace. The device is provided with a first tray 403, a second tray 404, a conveying mechanism 4 and a lifting mechanism 5, so that after the material is placed on the first tray 403 and sent to the furnace body 1, the material to be subsequently fired is placed on the second tray 404 in advance. After the firing of the material in the first tray 403 is completed, the lifting mechanism 5 and the conveying mechanism 4 send the first tray 403 to the initial position for the next firing preparation. The lifting mechanism 5 and the conveying mechanism 4 simultaneously send the material in the second tray 404 to the furnace body 1 for firing. The whole process can be carried out uninterruptedly, and non-stop furnace production can be achieved.
