The self-cleaning high-temperature roller heating furnace includes a furnace body 1, a plurality of rollers 2 and a cleaning mechanism 3. The plurality of rollers 2 are arranged in the furnace body 1 in a rolling manner at uniform intervals. The cleaning mechanism 3 includes a cleaning member 4 and a lifting drive assembly 5; the cleaning member 4 is arranged inside the furnace body 1 and is located below the roller 2. The cleaning member 4 can abut against the surface of the roller 2 to clean attachments on the surface of the roller 2; the output end of the lifting drive assembly 5 is connected to the cleaning member 4 to drive the cleaning member 4 to move in a direction close to or away from the roller 2.

[0031] The cleaning member 4 can directly contact the surface of the roller 2 to remove the deposits accumulated on the roller 2 during high-temperature operation, keep the surface of the roller 2 clean, and prevent the normal operation of the equipment from being affected by the accumulation of deposits. The output end of the lifting drive assembly 5 can drive the cleaning member 4 to move in a direction close to or away from the roller 2, so that the cleaning member 4 can contact the surface of the roller 2 when needed and adjust its position according to cleaning needs. The automated cleaning process reduces the need for manual cleaning, lowers maintenance costs and operational difficulty. By automatically cleaning the surface of the roller 2, downtime caused by excessive deposits on the surface of the roller 2 is reduced, the heating effect and rolling performance of the roller 2 are ensured, the working efficiency of the high-temperature roller heating furnace is improved, and the equipment can be ensured to operate stably for a long time under high-temperature conditions. Among them, the cleaning member 4 can be, but is not limited to, a scraper, etc., and is not specifically limited here.

[0032] Combine Figure 3 and Figure 4 As shown, in order to improve the stability of the lifting drive assembly 5, in some embodiments, the lifting drive assembly 5 includes a first driving member 51 and a lifting member, the first driving member 51 includes a driving motor 511 and a screw rod 512, the lifting member includes a lifting block 52, the screw rod 512 is arranged in the vertical direction, the lifting block 52 is screwed to the screw rod 512, the output end of the driving motor 511 is transmission-connected to one end of the screw rod 512, the output end of the driving motor 511 can drive the screw rod 512 to rotate and drive the lifting block 52 to move up and down in the vertical direction, through the screw connection structure between the screw rod 512 and the lifting block 52, the driving motor 511 can accurately control the up and down movement of the lifting block 52 to achieve precise height adjustment, wherein the screw rod 512 has high stability, is not prone to jamming or sliding problems, can maintain a reliable lifting function in a high temperature environment, and ensure the stable operation of the cleaning mechanism 3. In other embodiments, the first driving member 51 includes a cylinder driving member, which drives the piston in the cylinder to move by compressed air to achieve the lifting action.

[0033] Continue to combine Figure 3 and Figure 4As shown, in order to prevent excessive movement of the lifting member, in some embodiments, the lifting drive assembly 5 also includes a limiter 53, which can limit the moving distance of the lifting block 52 in the vertical direction; through the setting of the limiter 53, the lifting block 52 can be ensured to operate within the set upper and lower limit ranges, effectively limiting the maximum moving distance of the lifting block 52 in the vertical direction, avoiding excessive movement of the lifting block 52 due to driving errors or external factors, thereby avoiding damage to equipment or parts, reducing the time for manual adjustment and regulation, improving work efficiency, and achieving more automated and reliable operation. Specifically, the limiting member 53 is set as a limiting groove, and the drive motor 511, the screw rod 512 and the lifting block 52 are all set in the limiting groove.

[0034] Since the attachments may flow into the lifting drive assembly 5 after being cleaned, thereby causing the drive assembly to malfunction or performance degradation, in order to solve the above problem, as Figure 2As shown, in some embodiments, the cleaning mechanism 3 also includes a collection component 6, which is arranged below the cleaning member 4 and is used to collect attachments on the roller 2. The collection component 6 can collect the attachments cleaned by the cleaning member 4 in a timely and effective manner, effectively preventing these dirt from flying during the cleaning process and preventing them from contaminating the high-temperature roller heating furnace again, thereby improving the cleaning effect and work efficiency. Furthermore, the cleaning mechanism 3 also includes a drainage member 7, one end of the drainage member 7 is connected to the cleaning member 4, and the other end of the drainage member 7 is connected to the lifting member. The drainage member 7 can guide the attachments on the surface of the roller 2 into the collection component 6, reducing the pollution of the working area. The operator does not need to manually intervene to collect the attachments, effectively preventing the attachments from flowing into the lifting drive assembly 5, reducing the risk of wear and blockage, and reducing the failure rate of the equipment. Among them, the drainage member 7 can be an inclined guide plate, which is designed as an inclined plate-like structure, fixed below the cleaning member 4, tilted toward the collection component 6, and uses gravity to guide the attachments to slide into the collection component 6, effectively preventing the attachments from flowing back. Furthermore, the collection assembly 6 includes a collection trough 61, which is arranged below the cleaning member 4 and is slidably connected to the inner wall of the furnace body 1 in the horizontal direction; the sliding design of the collection trough 61 makes it possible to easily remove the collection trough 61 or move it to a more convenient area for cleaning when cleaning attachments, thereby reducing the complexity of manual operation; setting the collection trough 61 as a sliding connection can effectively utilize the space inside the furnace body 1, and keep the cleaning process neat and efficient without affecting the operation of other components.

[0035] Continue as Figure 2 As shown, in some embodiments, the collection assembly 6 further includes a second drive member 62, the output end of which is connected to the side wall of the collection trough 61 to drive the collection trough 61 to slide horizontally within the furnace body 1. The addition of the second drive member 62 automates the movement of the collection trough 61, eliminating the need for manual operator intervention and improving operational convenience and efficiency. The collection trough 61 can also be precisely adjusted to a desired position by the second drive member 62, ensuring the efficiency and effectiveness of the cleaning process and preventing the retention of deposits. The second drive member 62 can be, but is not limited to, an electric push rod, which is not specifically limited herein.

[0036] like Figure 1As shown, in order to further ensure the cleanliness of the interior of the self-cleaning high-temperature roller heating furnace, in some embodiments, the self-cleaning high-temperature roller heating furnace further includes a dustproof component 8, which includes a baffle 81 and a reset member 82.
