[0030] In the present embodiment, the first cleaning assembly loading device is arranged on the shaft surface of the external tangent roller inside and outside the sintering furnace, and the cleaning device is driven to move by the rotation of the external tangent roller itself without the need for additional power support. At the same time, the longitudinal fan and the longitudinal cleaning brush are coaxially connected by the structural design, so that the cleaning brush performs physical cleaning, and the upper fan generates negative pressure airflow to timely absorb the pollutants generated in the cleaning process. Not only is the secondary pollution caused by the flying of pollutants avoided, but also the structure is simple and compact through the coaxial connection, and the cleaning efficiency and equipment reliability are improved.

[0031] Further, the embodiment also comprises a second cleaning assembly for cleaning the outer roller 2 for the second time, which comprises a front arm cleaning brush 9 and a front arm fan 11 arranged transversely, and the front arm fan 11 is coaxially connected with the front arm cleaning brush 9; and the longitudinal fan 7 transmits wind energy to the front arm fan 11 through the air guide pipe, and the longitudinal fan 7 also discharges the impurities generated by cleaning through the air guide pipe.

[0032] In the embodiment, the first cleaning is to clean the tangential surface of the outer roller 2, and the second cleaning is to clean the axial surface of the outer roller 2.

[0033] In the embodiment, the first cleaning assembly cleans the longitudinal surface of the outer roller, and the second cleaning assembly cleans the axial surface of the outer roller transversely, so that the tangential surface and the axial surface of the outer roller are cleaned in all directions, the cleaning efficiency is improved, the accumulation of silver paste and other pollutants on the surface of the outer roller is effectively prevented, the surface of the outer roller is kept clean at all times, and the production quality of the solar cell is ensured.

[0034] Specifically, when the cleaning device works, the driving mechanism 1 drives the longitudinal fan 7 of the first cleaning assembly to start, and simultaneously drives the coaxially connected longitudinal cleaning brush 8 to rotate and clean the tangential surface of the outer roller 2. When the longitudinal fan 7 rotates, negative pressure is generated upward, and the impurities generated by cleaning enter the air guide pipe under the negative pressure and are discharged. In addition, when the negative pressure airflow passes through the front arm fan 11, the front arm fan 11 is driven to rotate, and since the front arm fan 11 is coaxially connected with the front arm cleaning brush 9, the second transverse cleaning of the outer roller 2 is realized, and a complete cleaning cycle is formed.

[0035] Further, in the embodiment, in order to increase the contact area with the axial surface of the outer roller 2, improve the friction and reduce the wear caused by hard contact, the first cleaning assembly loading device is provided with a groove 12 on the surface in contact with the axial surface of the outer roller 2, and plastic soft cotton is arranged in the groove 12.

[0037] Further, in the embodiment, the driving mechanism 1 comprises a motor and a driving wheel transmission assembly connected with the motor. Specifically, the gear transmission assembly comprises a driving wheel 31 connected with the motor, and a plurality of driven wheels 32 engaged with the driving wheel 31, each of the driven wheels 32 being connected with the longitudinal fan 7 and the longitudinal cleaning brush 8.

When the motor is started, the four sets of first cleaning assemblies are driven to rotate synchronously by the gear transmission assembly. Specifically, when the motor control device starts the motor, the driving wheel 31 drives the four driven wheels 32 to rotate, thereby driving the longitudinal fan 7 and the longitudinal cleaning brush 8 in each group to rotate synchronously. The longitudinal cleaning brush 8 cleans the tangential surface of the external roller 2 on both sides of the sintering furnace 13, and each longitudinal fan 7 generates negative pressure airflow. Each longitudinal fan 7 is connected with the inlet of the corresponding air duct, and the generated negative pressure airflow flows to the outlet through the air duct, in the process, the forearm fan 11 in the duct is driven to rotate, and at the same time, the impurities generated in the cleaning process are discharged through the pipeline system.
