DETAILED DESCRIPTION

[0021] The utility model will be further described below in combination with the drawings and embodiments.

[0022] Please refer to Figs. 1 to 3 A photovoltaic glass coating machine washing roller safety device, the main body is a rack 1, the inner side of the rack 1 is ingeniously configured with a belt conveying assembly 2, this assembly is specially used for stably and continuously conveying photovoltaic glass. On both sides of the rack 1, we symmetrically install solid mounting plates 3, which provide stable support for subsequent components.

[0023] On the installation plate 3, we carefully install the quantitative roller 4, which is responsible for the accurate coating of photovoltaic glass in the coating process. At the same time, the coating roller 5 is ingeniously arranged on the rack 1, which forms a potentially dangerous extrusion gap with the quantitative roller 4. In order to protect the safety of the operator, we specially install a plurality of pressing rollers 6 on the rack 1, which work together to ensure that the coating process of photovoltaic glass is stable and efficient.

[0024] In order to effectively prevent the accidental involvement of body parts such as palms in this dangerous extrusion gap, we specially install a blocking plate 9 between the two installation plates 3. The end of the blocking plate 9 is ingeniously designed with a connecting part 10 that can be tightly embedded in the installation slot 8 on the mounting seat 7. It is worth mentioning that the mounting seat 7 is tightly connected with the fixing screw 11 by screwing, and the connecting part 10 is ingeniously provided with a limiting hole 12. When the end of the fixing screw 11 is stably inserted into the limiting hole 12, a firm locking mechanism is formed, effectively preventing the connecting part 10 from accidentally falling out of the installation slot 8.

[0025] The design of the belt conveying assembly 2 is also unique. It includes a motor 13 fixed on the rack 1, and a driving shaft 14 and a driven shaft 15 connected to the rack 1 by precise rotary connection. The driving shaft 14 and the driven shaft 15 are efficiently connected by a tough belt 16. When the motor 13 starts, it will drive the driving shaft 14 to rotate quickly, and then transmit power to the driven shaft 15 through the belt 16, thereby realizing the stable conveying of photovoltaic glass.

[0026] At the top of the installation slot 8, we also specially design a chamfer 17. This design not only improves the aesthetics of the device, but more importantly, it greatly simplifies the process of installing the connecting part 10 into the installation slot 8, making the entire installation process smoother and more efficient.

[0027] Finally, the mounting seat 7 is stably fixed and connected with the installation plate 3 by screws 18. This connection method is not only simple and easy to implement, but also facilitates subsequent maintenance and disassembly work, providing great convenience for the operator.

[0028] The above is only an embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation based on the content of the present application specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the present application.
