Description

Technical Field

[0001] This utility model relates to the field of box-type resistance furnaces, and specifically to a box-type resistance furnace with automatic loading and unloading function. Background Technology

[0002] Box-type resistance furnaces are a common type of electric furnace, widely used in production and experimentation in fields such as ceramics, metallurgy, electronics, glass, chemicals, machinery, refractory materials, new material development, special materials, and building materials. A box-type resistance furnace mainly consists of two parts: the furnace body and the control box. The outer shell of the furnace body is made of high-quality steel plate with folded edges and welded, while the inner furnace chamber is a rectangular, integral furnace chamber made of refractory material. The furnace body exterior is typically treated with high-temperature and corrosion-resistant paint, while the furnace door is thickened and reinforced to prevent deformation. The furnace lining uses high-quality insulation cotton, providing excellent heat preservation. Furthermore, the furnace chamber temperature has a real-time monitoring function, facilitating continuous observation of the furnace temperature.

[0003] In current practice, manual loading and unloading are commonly used for box-type resistance furnaces. However, this method poses significant safety risks. Because box-type resistance furnaces generate high temperatures during operation, manual approach and handling can easily lead to burns or other accidents.

[0004] To mitigate these safety risks, some researchers have attempted to use robotic arms for automated loading and unloading. While robotic arms can, to some extent, prevent direct human contact with the high-temperature furnace and reduce the occurrence of accidents, their application also comes with some drawbacks. Robotic arms consume a significant amount of energy during operation, which not only increases production costs but may also have a certain environmental impact. Furthermore, the maintenance and upkeep of robotic arms are relatively complex, requiring operation by specialized technicians. Utility Model Content

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A box-type resistance furnace with automatic loading and unloading function includes a furnace body, connecting pipes, furnace cavity, sealing door and sliding rail rack. The connecting pipes are installed on the furnace body, and the furnace cavity is opened at the front end of the furnace body. Multiple sliding rail racks are installed in the furnace cavity, and the sealing door is installed on the furnace body by a locking device and a hinge device.

[0008] The furnace body has an opening with a mounting bracket, and the mounting bracket is connected to a rotating bracket via a rotating assembly. The rotating bracket has a fixed seat at its corner, and the fixed seat can be adjusted in angle via the rotating assembly and the rotating bracket.

[0009] The upper end of the fixed base is connected to a telescopic pipe via a connecting frame. A first telescopic device is installed at the outer end of the telescopic pipe.

[0010] As an optional solution of this utility model, the mounting bracket is located below the furnace cavity opening, and an anti-slip rubber strip is provided at the connection between the mounting bracket and the furnace body. The mounting bracket is fixed to the furnace body by bolts. The mounting bracket is fixed to the bracket of the rotating component by bolts and nuts. The bracket of the rotating component is provided with a rotating shaft and a driving part. The driving part drives the rotating shaft to rotate.

[0012] As an optional solution of this utility model, the connecting frame is fixed to the telescopic pipe by bolts. The telescopic pipe is divided into a large pipe and a small pipe. The small pipe is placed inside the large pipe and extends and retracts along the large pipe. The angle adjustment frame is connected to the small pipe by a rotating shaft. The telescopic end of the second telescopic device is connected to the angle adjustment frame by a rotating shaft.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] By coordinating the rotation mechanism, telescopic mechanism, and grippers, automated loading and unloading operations are achieved for the sliding rail shelving system, eliminating the tedious and time-consuming manual handling and significantly improving work efficiency. Automated loading and unloading reduces reliance on manual labor, lowers labor costs, and also reduces the physical exertion of workers. Furthermore, automated loading and unloading avoids direct contact between workers and the high-temperature furnace cavity and materials, reducing the risk of burns and improving workplace safety.

[0017] The combined use of the telescopic mechanism and the angle adjustment frame allows for precise position and angle adjustment of the sliding rail rack, ensuring accurate and stable material entry into the furnace for processing, thus improving operational precision and reliability.
