DETAILED DESCRIPTION

[0016] The photovoltaic glass cleaning device includes a main frame 1, a sub-frame 3, a lifting adjuster 2, a sliding mechanism A4, a sliding mechanism B8, an active cone wheel 10, a driven cone wheel 19, an upper cleaning roller 5 and a lower cleaning roller 9 (see the attached manual for details). Figure 1 ).

[0017] The main frame 1 is equipped with a sub-frame 3 via a lifting adjuster 2 (see the appendix of the manual). Figure 1 and 5 The lifting adjuster 2 includes a vertical screw rod 25, a transmission sprocket 27, a transmission chain 28 and a vertical screw rod sleeve 26 (see the attached manual). Figure 1 and 3 ).

[0018] Multiple groups of vertical screw rods 25 are symmetrically mounted on the sub-frame 3 through bearing seats; vertical screw rod sleeves 26 are mounted on the main frame 1 below the vertical screw rods 25; the vertical screw rods 25 are connected to the corresponding vertical screw rod sleeves 26; a transmission sprocket 27 is mounted on the top of the vertical screw rod 25; the transmission sprockets 27 are interconnected by a transmission chain 28; a drive motor is mounted on the sub-frame 3; and the drive motor is connected to a group of vertical screw rods 25.

[0019] During operation, the drive motor can drive the vertical screw 25 to rotate forward or reverse through the transmission sprocket 27 and the transmission chain 28; during the rotation of the vertical screw 25, the vertical screw sleeve 26 can cooperate with the auxiliary frame 3 to move closer to or away from the main frame 1.

[0020] The upper cleaning roller 5 is installed on the auxiliary frame 3 through a symmetrically arranged sliding mechanism A4 (see the appendix of the manual). Figure 1 and 2 ).

[0021] The sliding mechanism A4 includes an assembly frame 14, a sliding plate 16, a guide slide 15 and a support spring 17; the assembly frame 14 is mounted on the auxiliary frame 3; the interior of the assembly frame 14 is slidably mounted with a sliding plate 16 through the guide slide 15 (see the appendix of the manual). Figure 7 and 8 ).

[0022] A support spring 17 is mounted on the guide slide bar 15 above the sliding plate 16; an upper cleaning roller 5 is mounted between the sliding plates 16 of the sliding mechanism A4 via a bearing seat.

[0023] The purpose of arranging the sliding mechanism A4 in this way is to enable the sliding plate 16 to overcome the elastic force of the supporting spring 17 and drive the upper cleaning roller 5 to move upward when the sliding plate 16 is subjected to force during operation.

[0024] The ends of the upper cleaning roller 5 are respectively equipped with driven cone wheels 19 (see the appendix of the manual) through the adjustment mechanism 6. Figure 2 and 5 The adjustment mechanism 6 includes a fork plate 22, an adjustment screw rod 24 and a guide slide rod 21 (see the appendix of the specification). Figure 2 and 5 ).

[0025] One end of the upper cleaning roller 5 passes through the sliding plate 16 and slides through the long key 18 to install a driven cone wheel 19; a return spring 20 is installed between the driven cone wheel 19 and the sliding plate 16 (see the appendix of the manual). Figure 5 When the driven cone wheel 19 is subjected to force, it can slide back and forth along the long key 18; when the driven cone wheel 19 rotates, it can drive the upper cleaning roller 5 to rotate synchronously through the long key 18.

[0026] A toggle fork plate 22 is slidably mounted on the assembly frame 14 above the driven cone wheel 19 via a guide slide 21; an adjusting screw 24 is mounted on the main frame 1 via an adjusting motor 23; the adjusting screw 24 is connected to the corresponding toggle fork plate 22; when the adjusting screw 24 rotates forward, the toggle fork plates 22 move closer to each other; when the adjusting screw 24 rotates reversely, the toggle fork plates 22 move away from each other (see the appendix of the instruction manual). Figure 2 and 5 ).

[0027] When working in this way, the adjusting screw 24 drives the shift fork plates 22 to move closer to each other, thereby squeezing the driven conical wheel 19 to move inward along the long key 18; when the adjusting screw 24 drives the shift fork plates 22 to separate from each other, the return spring 20 can push the driven conical wheel 19 to move outward along the long key 18.

[0028] The main frame 1 below the upper cleaning roller 5 is equipped with a lower cleaning roller 9 (see the appendix of the manual) through a symmetrically arranged sliding mechanism B8. Figure 1 、 2 and 5).

[0029] The sliding mechanism B8 includes an assembly frame 14, a sliding plate 16, a guide slide 15 and a support spring 17. The assembly frame 14 is mounted on the main frame 1. The sliding plate 16 is mounted inside the assembly frame 14 via the guide slide 15. The support spring 17 is mounted on the guide slide 15 below the sliding plate 16 (see the appendix of the manual). Figure 7 and 8 ).

[0030] The lower cleaning roller 9 (see the appendix of the specification) is installed between the sliding plates 16 of the sliding mechanism B8 through the bearing seat. Figure 7 and 8 When the sliding plate 16 is subjected to force, it can drive the lower cleaning roller 9 to slide up and down along the guide slide bar 15.

[0031] The two ends of the lower cleaning roller 9 are fixed with driving cone wheels 10. The driving cone wheel 10 is in contact with the corresponding driven cone wheel 19. When the driving cone wheel 10 rotates, the upper cleaning roller 5 can be driven to rotate synchronously by the driven cone wheel 19.

[0032] One end of the lower cleaning roller 9 is equipped with a passive pulley 11; a driving pulley 12 is installed on the main frame 1 on one side of the passive pulley 11 through a motor; the driving pulley 12 and the passive pulley 11 are connected to each other through a transmission belt 13 (see the attached manual). Figure 1 ). During the rotation of the driving pulley 12 driven by the motor, the lower cleaning roller 9 can be driven to rotate through the passive pulley 11 and the transmission belt 13.

[0033] A plurality of transmission rollers 29 are installed at intervals on the main frame 1. During operation, an external power mechanism can drive each transmission roller 29 to rotate synchronously. During the synchronous rotation of the transmission rollers 29, the photovoltaic glass can be driven forward.

[0034] The middle part of the main frame 1 is provided with a lower purge air knife 30; the auxiliary frame 3 above the lower purge air knife 30 is provided with an upper purge air knife 31. The lower purge air knife 30 and the upper purge air knife 31 are both arranged in an inclined manner (see the appendix of the manual). Figure 1 and 6 When the photovoltaic glass moves forward during operation, the dry hot air blown by the lower purge air knife 30 and the upper purge air knife 31 can clean and dry the upper and lower surfaces of the photovoltaic glass.

[0035] The upper cleaning nozzle 32 is mounted on the auxiliary frame 3 on the side of the upper cleaning roller 5; the lower cleaning nozzle 7 is mounted on the main frame 1 on the side of the lower cleaning roller 9 (see the attached manual). Figure 2 and 6 When the photovoltaic glass passes between the upper cleaning nozzle 32 and the lower cleaning nozzle 7 during operation, the cleaning liquid sprayed from the upper cleaning nozzle 32 and the lower cleaning nozzle 7 can clean the upper and lower surfaces of the photovoltaic glass.

[0036] The photovoltaic glass cleaning device can drive the lower cleaning roller 9 to rotate through the passive pulley 11 and the transmission belt 13 during the rotation of the motor driven active pulley 12. During the rotation of the lower cleaning roller 9, the upper cleaning roller 5 can be driven to rotate synchronously through the active conical wheel 10 and the driven conical wheel 19.

[0037] When the rotating transmission roller 29 drives the photovoltaic glass to move on the main frame 1, the cleaning liquid sprayed from the upper cleaning nozzle 32 and the lower cleaning nozzle 7 can clean the upper and lower surfaces of the photovoltaic glass.

[0038] As the moving photovoltaic glass passes between the lower cleaning roller 9 and the upper cleaning roller 5, the rotating lower cleaning rollers 9 and 5 clean the upper and lower surfaces of the photovoltaic glass. Driven by the drive roller 29, the cleaned photovoltaic glass then passes between the lower purge air knife 30 and the upper purge air knife 31. The dry hot air blown by the lower purge air knife 30 and the upper purge air knife 31 cleans and dries the upper and lower surfaces of the photovoltaic glass. In this way, the cleaning device can complete the cleaning and drying of the photovoltaic glass.

[0039] During the production process, if the bristles on the lower cleaning roller 9 and the upper cleaning roller 5 are worn out and the distance between the lower cleaning roller 9 and the upper cleaning roller 5 needs to be adjusted, or if the distance between the lower cleaning roller 9 and the upper cleaning roller 5 needs to be adjusted for photovoltaic glass of different thicknesses, the cleaning device needs to be turned off first, and then the fork plates 22 are driven to move closer to or apart from each other by adjusting the motor 23 and the screw rod 24.

[0040] When the screw rod 24 is adjusted to drive the fork plates 22 to move closer to each other, the driven conical wheel 19 can be squeezed to move inward along the long key 18; when the driven conical wheel 19 moves inward, the driven conical wheel 19 will squeeze the active conical wheel 10 through the conical surface, so that the driven conical wheel 19 and the active conical wheel 10 can overcome the elastic force of the support spring 17 through the sliding plate 16 and drive the lower cleaning roller 9 and the upper cleaning roller 5 to separate from each other, so as to achieve the purpose of adjusting the distance between the lower cleaning roller 9 and the upper cleaning roller 5.

[0041] When the adjusting screw 24 drives the fork plates 22 to separate from each other, the return spring 20 can push the driven conical wheel 19 to move outward along the long key 18. During the outward movement of the driven conical wheel 19, the support spring 17 will push the lower cleaning roller 9 and the upper cleaning roller 5 closer to each other under the elastic force of the support spring 17, so that the distance between the lower cleaning roller 9 and the upper cleaning roller 5 can be adjusted closer.

[0042] The photovoltaic glass cleaning device has a compact structure and ingenious design. During operation, the distance between the upper cleaning roller 5 and the lower cleaning roller 9 can be adjusted by adjusting the lateral position between the driven conical wheels 19. This solves the problems of high energy consumption and inability to adjust the cleaning interval in existing glass cleaning devices, and is particularly suitable for the needs of photovoltaic glass production and cleaning.
