Detailed Embodiments

[0026] Embodiment 1

[0027] As Figures 1 - 3 shown, a cleaning mechanism for the lower roller of a photovoltaic glass rolling machine proposed in this embodiment includes an insulation box 1, a lip brick 3, an upper roller 41, a lower roller 42, a spray head 11, and a water supply mechanism.

[0028] The upper end of the insulation box 1 has a groove 101. A through hole communicating with its inner cavity is opened at the upper end of the insulation box 1, and a filter screen 7 is installed inside the through hole. The top end of the inner wall of the insulation box 1 is provided with a funnel 8. The bottom end of the funnel 8 is connected to a drain pipe 9, and a one-way valve 10 is installed on the drain pipe 9. When the water at the upper end of the insulation box 1 runs out, the one-way valve 10 automatically closes, thereby reducing the heat loss inside the insulation box 1.

[0029] Both ends of the upper roller 41 are communicated with a hollow rotating pipe a51, and both ends of the lower roller 42 are communicated with a hollow rotating pipe b52. Two brackets 2 are arranged side by side on the insulation box 1. The upper roller 41 is rotatably installed between the two brackets 2 through the hollow rotating pipe a51, and the lower roller 42 is rotatably installed between the two brackets 2 through the hollow rotating pipe b52. A power assembly for driving the upper roller 41 and the lower roller 42 to rotate synchronously is installed on the bracket 2. The power assembly includes a motor 191, a gear a192, a gear ring a193, two gear rings b231 and two gears d232. Among them, the motor 191 is installed on the bracket 2, the gear a192 is installed on the output shaft of the motor 191, the gear b193 is installed on the hollow rotating pipe a51 and meshed with the gear a192. The two gear rings b231 are respectively installed on the hollow rotating pipe a51 and the hollow rotating pipe b52. The two gears d232 are both rotatably installed on the bracket 2. The two gears d232 are meshed with each other, and the two gears d232 are respectively meshed with the gear rings b231 on both sides.

[0030] The spray head 11 is installed between the two brackets 2. A baffle a121 and a baffle b122 are connected between the two brackets 2. The spray head 11 is located between the baffle a121 and the baffle b122. The sprayed water can be prevented from overflowing by the arranged baffle a121 and baffle b122.

[0031] The water supply mechanism includes a water tank 16, a pump 17, two outlet end rotary joints 181 and two inlet end rotary joints 182. Among them, the two outlet end rotary joints 181 are respectively installed on the left hollow rotating pipe a51 and the hollow rotating pipe b52, and the two inlet end rotary joints 182 are respectively installed on the right hollow rotating pipe a51 and the hollow rotating pipe b52. Communication pipes b242 are connected between the two inlet end rotary joints 182 and the inner cavity of the insulation box 1. The output end of the pump 17 is connected to the spray head 11, and its input end is connected to the water tank 16. Communication pipes a241 are connected between the water tank 16 and the two outlet end rotary joints 181.

[0032] A heating device 6 is installed inside the insulation box 1, a temperature sensor is installed inside the water tank 16, and a controller is installed outside the insulation box 1. When the temperature sensor detects that the water temperature flowing into the water tank 16 is relatively low, the controller controls the switch of the heating device 6 to be turned on, so that the heating of the water body inside the insulation box 1 can be realized until the water temperature inside the insulation box 1 rises to the set range value interval. Before starting the cleaning, the water body needs to be heated and warmed first.

[0033] The surfaces of the upper roller 41 and the lower roller 42 are in contact with the high-temperature glass liquid, thereby heating the water inside the upper roller 41 and the lower roller 42. During the cleaning process of the lower roller 42, the pump 17 is started to suck the water inside the insulation box 1 into the interior of the lower roller 42 and the lower roller 42. The water is heated by the upper roller 41 and the lower roller 42 and then flows into the water tank 16. Finally, it is sprayed to the surface of the lower roller 42 through the nozzle 11, thereby cleaning the lower roller 42. By using heated water during the cleaning process, the lower roller 42 can be prevented from being damaged due to a sudden drop in temperature, and the upper roller 41 and the lower roller 42 can be cooled at the same time, which has strong practicality.

[0034] Example 2

Compared with the first embodiment, in the present embodiment, a sponge mounting roller 13 and a pressure roller 15 are provided between the two brackets 2.

The pressure roller 15 is provided with a rotating shaft b151. The pressure roller 15 is rotatably mounted between the two brackets 2 via the rotating shaft b151. A water-absorbing sponge 14 is sleeved on the sponge mounting roller 13. The water-absorbing sponge 14 is in contact with both the lower roller 42 and the pressure roller 15. The rotating shaft a131 is connected to the hollow rotating tube b5. 2 is connected with a transmission component a, which includes a pulley a221, a pulley b222 and a belt a223, wherein the pulley a221 and the pulley b222 are respectively installed on the hollow rotating tube b52 and the rotating shaft a131, and the pulley a221 and the pulley b222 are connected by the belt a223.

[0036] Through the setting of the transmission component a, the lower roller 42 can drive the sponge installation roller 13 to rotate when it rotates, and the pressure roller 15 is driven to rotate under the transmission action of the transmission component b. The sponge installation roller 13 drives the water-absorbing sponge 14 to rotate during the rotation process. The water-absorbing sponge 14 can absorb moisture from the surface of the lower roller 42. The pressure roller 15 is pressed tightly on the side of the water-absorbing sponge 14, thereby squeezing out the moisture in the water-absorbing sponge 14 to achieve continuous water absorption of the water-absorbing sponge 14.

[0037] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
