It combines roller hearth heating and tunnel structures, and transports products or materials out of the furnace through a conveyor belt to achieve a continuous heating process.

[0003] In a Chinese patent with application number 202321945434.X, a roller bottom tunnel heating furnace is disclosed, which is fixedly connected with a cleaning mechanism at the top between the opposite sides of two chains. The motor drives the gear to rotate through the first rotating rod, and the gear drives the second rotating rod to rotate accordingly under the drive of the chain, so that the chain can transmit the cleaning mechanism and clean the surface of the transmission roller to prevent impurities from adhering to the transmission roller and causing no pollution to the workpiece to be baked subsequently.

[0004] With respect to the above-mentioned related technologies, the inventors believe that when the above-mentioned device is actually used, since the cleaning direction of the cleaning mechanism is consistent with the conveying direction of the transmission roller, the transmission roller will rotate automatically following the movement of the cleaning mechanism during the cleaning process. This results in the inability to effectively remove some more stubborn stains and lacks certain practicality.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0008] A continuous roller hearth furnace comprises a base, a furnace body is fixedly mounted on the top of the base, a support groove is provided on the base, a plurality of transmission rollers are movably arranged in the support groove, a support cover is fixedly mounted on the bottom of the base, a motor 1 is fixedly mounted on the support cover, a movable frame is movably arranged in the support cover, a motor 2 is fixedly mounted on the movable frame, and a cleaning mechanism is installed at the output end of the motor 2.

[0009] Preferably, two groups of rotating rods are rotatably mounted on the support cover, wherein one group of rotating rods is connected to the output end of the motor 1, and a sprocket 1 is fixedly mounted on each of the rotating rods, and the sprockets are connected by a chain 1.

[0010] Preferably, two groups of slide grooves are symmetrically provided on the support cover, and pulleys cooperating with the slide grooves are provided on both sides of the movable frame, and one group of the pulleys is movably connected to the chain through a round rod.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] By starting motor 2, motor 2 drives the movable rod to rotate, the movable rod drives chain 2 to rotate through sprocket 2, and chain 2 drives the soft brush on the rubber pad to rotate through the connecting rod. Since the rotation direction of the soft brush is perpendicular to the rotation direction of the transmission roller, the transmission roller will not be affected when the soft brush rotates. When the soft brush cleans the stains on the transmission roller, it will not be unclean due to the same-direction movement, thereby enhancing the practicability of the device.
