Technical Field

[0001] This utility model relates to the field of motor core processing technology, specifically a tunnel furnace for heat treatment of motor cores. Background Technology

[0002] The motor core is an important component of a motor, capable of establishing and guiding a magnetic field. In order to eliminate the internal stress generated during the processing of the motor core by stamping, welding and other operations, and to improve the magnetic properties of the core, the motor core needs to be heat-treated. This requires the use of a tunnel furnace for heat treatment of motor cores.

[0003] In order to reduce heat loss and ensure the heat treatment effect, the heat treatment area of ​​the existing motor core heat treatment tunnel furnace is usually a narrow tunnel. During operation, the operator usually adds the motor core into the tunnel furnace through the feeding port, and then the motor core is transported to the heat treatment area by the conveyor belt. After heat treatment, it is sent out of the tunnel furnace.

[0004] Existing tunnel furnaces for heat treatment of motor cores have the following problems: the heat treatment area of ​​the tunnel furnace is usually a narrow tunnel, which makes it inconvenient to clean the internal conveyor belt, resulting in a long cleaning time, affecting the efficiency of heat treatment and reducing the production rate of motor cores. To address this, we propose a tunnel furnace for heat treatment of motor cores. Utility Model Content

The rear end of the output shaft of the second motor 7 is fixedly connected to the front end of the rotating shaft on the right side. The input end of the second motor 7 is electrically connected to the output end of the microcontroller 2. A fan 8 is provided in the mounting port on the upper surface of the tunnel furnace 1. Electric heating wires 9 are provided at the upper part of the interior of the tunnel furnace 1, and the electric heating wires 9 are distributed in an S-shape. Located below the blower 8, the input ends of the blower 8 and the electric heating wire 9 are electrically connected to the output ends of the microcontroller 2. A collection box 10 is slidably connected in the slot at the lower end of the front side of the tunnel furnace 1. The front side of the collection box 10 is equipped with a handle 11. When heat treatment of the motor core is required, the operator adds the motor core into the tunnel furnace 1 through the feeding port, and then operates the microcontroller 2 to turn on the second motor 7. The output shaft of the second motor 7 drives the right conveyor roller 5 to rotate through the rotating shaft. The rotation of the right conveyor roller 5 drives the left conveyor roller 5 to rotate through the conveyor belt 6, transporting the motor core to the heat treatment area. Then, the blower 8 and the electric heating wire 9 are turned on. The blower 8 draws air into the tunnel furnace 1. The air temperature rises after passing through the electric heating wire 9, heat-treating the motor core below. After heat treatment, the motor core is sent out of the tunnel furnace 1 by the conveyor belt 6. The cleaned impurities fall into the collection box 10, which can be removed by the operator through the handle 11.

[0022] Cleaning mechanism 3 includes a rotating rod 301, a cleaning roller 302, bristles 303, a gear 304, a slide rail 305, and a rack 306. A uniformly distributed rotating rod 301 is rotatably connected between the front and rear walls at the lower end of the tunnel furnace 1. A cleaning roller 302 is fixedly fitted onto the middle of the outer surface of each rotating rod 301. Bristles 303 (steel bristles) are uniformly distributed on the outer surface of each cleaning roller 302. A cleaning rod 302 is fixedly fitted onto the front end of the outer surface of each rotating rod 301. The tunnel furnace 1 has gears 304, and a slide rail 305 is fixedly connected to the front wall. A rack 306 is slidably connected inside the slide rail 305. Each of the three gears 304 meshes with a rack 306.

The input end of the motor 4 is electrically connected to the output end of the microcontroller 2. When the conveyor belt 6 needs to be cleaned, the motor 4 is turned on. The output shaft of the motor 4 drives the rotating shaft 308 to rotate. The rotation of the rotating shaft 308 drives the limiting rod 310 to rotate around the rotating shaft 308 through the connecting rod 309. The limiting rod 310 both rotates and slides in the limiting groove 307. The rotation of the limiting rod 310 drives the rack 306 to reciprocate left and right in the slide rail 305 through the limiting groove 307. The reciprocating motion of the rack 306 drives the rotating rod 301 to rotate through the meshing gear 304, thereby causing the cleaning roller 302 to rotate and the brush bristles 303 to clean the conveyor belt 6.

[0023] The working principle of the tunnel furnace for heat treatment of motor cores provided by this utility model is as follows: When heat treatment of motor cores is required, the operator adds the motor cores into the tunnel furnace 1 through the feeding port, and then controls the microcontroller 2 to turn on the second motor 7. The output shaft of the second motor 7 drives the right conveyor roller 5 to rotate through the rotating shaft. The rotation of the right conveyor roller 5 drives the left conveyor roller 5 to rotate through the conveyor belt 6, transporting the motor cores to the heat treatment area. Then, the blower 8 and the electric heating wire 9 are turned on. The blower 8 draws air into the tunnel furnace 1. The air temperature rises after passing through the electric heating wire 9, and the motor cores below are heat treated. After heat treatment, the motor core is conveyed out of the tunnel furnace 1 by the conveyor belt 6. When the conveyor belt 6 needs to be cleaned, the motor 4 is turned on. The output shaft of the motor 4 drives the rotating shaft 308 to rotate. The rotation of the rotating shaft 308 drives the limiting rod 310 to rotate around the rotating shaft 308 through the connecting rod 309. The limiting rod 310 rotates and slides in the limiting groove 307. The rotation of the limiting rod 310 drives the rack 306 to reciprocate left and right in the slide rail 305 through the limiting groove 307. The reciprocating motion of the rack 306 drives the rotating rod 301 to rotate through the meshing gear 304, thereby causing the cleaning roller 302 to rotate. The brush bristles 303 clean the conveyor belt 6. The cleaned impurities fall into the collection box 10, and the staff can take out the collection box 10 through the handle 11.
