Description

Technical Field

[0001] The present invention relates to the technical field of flat glass cleaning, and in particular to an eco-friendly and environmentally friendly flat glass cleaning device and a cleaning method. Background Art

[0002] Flat glass refers to unprocessed, flat sheets of glass with a smooth surface and excellent optical properties. It is typically colorless and transparent, but can also be made into colored glass by adding certain metal oxides. It offers excellent light transmittance and perspective, allowing light to pass through evenly. It also possesses a certain mechanical strength, capable of withstanding loads such as wind pressure and its own weight.

[0003] During the production and processing of flat glass, dust and debris remaining from the processing will adhere to the formed flat glass. A cleaning device can rinse the flat glass to obtain a clean surface. However, existing cleaning equipment generally uses a cleaning brush plate to abut the flat glass and then move back and forth relative to the flat glass. During the cleaning process, the dirt attached to the cleaning brush plate cannot be removed in time, and the dirt will repeatedly rub on the flat glass, which will not only scratch the glass, but also make it difficult to clean the dirt smoothly, which is not conducive to achieving sufficient cleaning of the flat glass. For this reason, an ecological and environmentally friendly cleaning device and cleaning method for flat glass are provided to solve the above-mentioned existing technical problems.

DETAILED DESCRIPTION

[0034] The technical solution of the present invention is further described in detail below in conjunction with specific embodiments:

[0035] First embodiment

[0036] See also Figures 1-10 A flat glass ecological and environmentally friendly cleaning device includes a base plate 1, with a door frame I3 and a door frame II4 fixed at both ends of the base plate 1, a supporting plate 2 fixed on the base plate 1, a flat glass 5 installed on the supporting plate 2, a motor I12 fixed on the supporting plate 2, a screw rod 24 coaxially fixed to the output shaft of the motor I12, a sliding frame 6 slidably mounted on the supporting plate 2 is threadedly sleeved on the screw rod 24, a lifting plate 30 is vertically slidably mounted on the sliding frame 6, a connecting spring 31 is fixed between the lifting plate 30 and the sliding frame 6, and a cleaning brush plate opposite to the flat glass 5 is fixed at the bottom of the lifting plate 30 22. The sliding frame 6 is provided with a push transmission assembly for driving the cleaning brush plate 22 to move vertically downward. The sliding frame 6 is provided with a locking assembly for locking the push transmission assembly in position. A piston cylinder 17 is fixed on the sliding frame 6. A piston disc 46 is sealingly and slidingly installed in the piston cylinder 17. A flushing assembly is connected to the piston cylinder 17. The piston disc 46 is provided with a sliding frame 40. A water intake transmission assembly for driving the sliding frame 40 to reciprocate is provided on the sliding frame 6. A friction cleaning assembly for cleaning the bottom surface of the cleaning brush plate 22 is provided at one end of the bottom plate 1 close to the door frame I3.

[0037] A method for cleaning flat glass using an eco-friendly flat glass cleaning device comprises the following steps:

[0038] S1: Install the flat glass 5 on the supporting plate 2 and fix it, and connect the piston cylinder 17 to the clean water source;

[0039] S2: The motor I12 drives the screw 24 to rotate forward, so that the sliding frame 6 moves toward the door frame II4, and the surface of the flat glass 5 is sprayed with water through the washing component;

[0040] S3: The motor I12 drives the screw rod 24 to rotate in the opposite direction, so that the sliding frame 6 moves toward the door frame I3, and the cleaning brush plate 22 scrapes and cleans the surface of the flat glass 5;

[0041] S4: The sliding frame 6 is adjusted to above the friction cleaning assembly, and the bottom surface of the cleaning brush plate 22 is cleaned by the friction cleaning assembly.

[0042] Specifically, the flat glass 5 is fixed by adsorption through a clamp or an electric suction cup installed on the supporting plate 2, ensuring higher stability when cleaning the surface of the flat glass 5. The set motor I12 can drive the screw 24 to rotate, and the screw 24 drives the sliding frame 6 to slide, so that the lifting plate 30 drives the cleaning brush plate 22 to slide and clean the surface of the flat glass 5. Among them, the set flushing component can flush and spray the surface of the flat glass 5, and then the cleaning brush plate 22 moves down and contacts the flat glass 5 for sliding cleaning.

[0043] Second embodiment

[0044] See also Figures 1-10 On the basis of Example 1, in addition, the push transmission assembly of the device includes a positioning roller 8 rotatably mounted on the sliding frame 6, a push frame 19 corresponding to the lifting plate 30 is fixed on the positioning roller 8, and an L-shaped plate 14 corresponding laterally to the push frame 19 is fixed on the door frame II4.

[0045] When the sliding frame 6 of the present device slides toward the portal frame II4, after the pushing frame 19 is pushed by the L-shaped plate 14, the positioning roller 8 and the L-shaped plate 14 rotate. At this time, the lower end of the L-shaped plate 14 pushes the lifting plate 30 to move vertically downward. At this time, the lifting plate 30 drives the cleaning brush plate 22 to move downward and abut against the surface of the flat glass 5. Subsequently, when the sliding frame 6 moves toward the portal frame I3, the cleaning brush plate 22 scrapes and cleans the surface of the flat glass 5.

[0046] Among them, the locking assembly includes an extension plate 33 fixed on the sliding frame 6, a sliding column 35 is slidably installed on the extension plate 33, a positioning frame 9 is fixed on the sliding column 35, a push spring 34 is fixed between the positioning frame 9 and the extension plate 33, a plurality of circumferentially evenly distributed inclined grooves 37 are opened on the positioning roller 8, a wedge plate 36 that is plugged and adapted to the inclined grooves 37 is fixed on the positioning frame 9, a wedge block 10 is vertically slidably installed on the positioning frame 9, a vertical spring 32 is fixed between the wedge block 10 and the positioning frame 9, and the wedge surface of the door frame I3 corresponds horizontally to that of the wedge block 10.

[0047] Through the above arrangement, when the L-shaped plate 14 rotates and pushes the lifting plate 30, the positioning roller 8 rotates relative to the positioning frame 9. At this time, the wedge plate 36 is clamped in the corresponding inclined groove 37, thereby achieving an angle locking effect on the positioning roller 8 and the pushing frame 19, that is, ensuring that the cleaning brush plate 22 can maintain contact with the flat glass 5 when sliding toward the door frame I3, thereby ensuring that the flat glass 5 is fully cleaned.

[0048] When the sliding frame 6 moves toward the portal frame I3, the wedge block 10 is pushed and drives the positioning frame 9 away from the positioning roller 8, so that the wedge plate 36 is separated from the inclined groove 37, and the positioning roller 8 rotates in the opposite direction and resets. Then the wedge block 10 moves vertically downward relative to the positioning frame 9, and the wedge block 10 moves to its top and abuts against the portal frame I3. At this time, after the push spring 34 is reset, the wedge plate 36 is plugged into the inclined groove 37, and the push frame 19 is reset, that is, the cleaning brush plate 22 moves up to be reset.

[0049] Through the above, the reciprocating motion of the sliding frame 6 realizes the repeated unidirectional sliding cleaning of the flat glass 5 by the cleaning brush plate 22, which greatly improves the cleaning efficiency of the flat glass 5 and avoids the dirt attached to the cleaning brush plate 22 moving back and forth relative to the flat glass 5 to cause secondary pollution and damage to the flat glass 5.

[0050] In addition, the flushing assembly of this device includes a support frame 7 fixed to the end of the sliding frame 6. A liquid inlet pipe 39 and a liquid outlet pipe 41 are connected and installed on the piston cylinder 17. The liquid inlet pipe 39 and the liquid outlet pipe 41 are both installed with a one-way valve 38. A liquid distribution pipe 11 connected to the liquid outlet pipe 41 is fixed to the support frame 7. A plurality of equally spaced flushing nozzles 23 are installed at the bottom of the liquid distribution pipe 11. The water intake transmission assembly includes a turntable 16 rotatably mounted on the sliding frame 6. A circular frame 47 is fixed to the sliding frame 40. A pin 48 eccentrically hinged to the turntable 16 is slidably mounted within the circular frame 47. The water intake transmission assembly also includes a friction wheel 15 coaxially fixed to the turntable 16. A friction plate 13 is horizontally fixed between the portal frame I3 and the portal frame II4. The friction wheel 15 is in frictional contact with the friction plate 13.

[0051] Among them, a check disk 18 is coaxially fixed on the friction wheel 15, and a number of circumferentially evenly distributed wedge grooves 49 are opened on the check disk 18. A fixed block 45 is fixed on the sliding frame 6, and a vertical rod 44 is vertically slidably installed on the fixed block 45. A positioning wedge tooth 42 that is engaged in the wedge groove 49 is fixed on the vertical rod 44, and a vertical spring 43 is fixed between the positioning wedge tooth 42 and the fixed block 45.

[0052] Through the above arrangement, when the sliding frame 6 slides toward the portal frame II4, the friction wheel 15 and the friction plate 13 rotate by friction transmission, the friction wheel 15 drives the turntable 16 to rotate, the turntable 16 drives the pin 48 to rotate, and the pin 48 drives the circular frame 47 to reciprocate. At this time, the sliding frame 40 drives the piston plate 46 to slide back and forth relative to the piston cylinder 17. Under the unidirectional conduction effect of the one-way valve 38, the liquid inlet pipe 39 connected to the external clean water source is discharged from the liquid outlet pipe 41 through the piston cylinder 17 to achieve cleaning. After passing through the liquid distribution pipe 11, the water is discharged from multiple flushing nozzles 23, and the positioning wedge teeth 42 provided can fix the check disk 18 in one direction, that is, the check disk 18 cannot be reversed. When the sliding frame 6 moves toward the door frame I3, the flushing nozzle 23 will not discharge water, so that when the cleaning brush plate 22 does not contact the flat glass 5, the flat glass 5 is subjected to the spraying and flushing effect, and the cleaning brush plate 22 can be subjected to the alternating and repeated cleaning actions of the spraying and scraping brush plate 22, which greatly improves the cleaning effect of the flat glass 5.

[0053] In addition, the friction cleaning assembly of the present device includes two pairs of conveying rollers 21 rotatably mounted on the portal frame I3, the conveying rollers 21 are driven by a brush belt 20, a translation frame 26 is slidably mounted on the supporting plate 2, an upper roller 28 abutting the brush belt 20 is rotatably mounted on the translation frame 26, and the height of the upper roller 28 is higher than that of the conveying roller 21, a motor III29 is mounted on the supporting plate 2, a threaded rod 25 is driven and connected to the motor III29, and the translation frame 26 is threadedly mounted on the threaded rod 25.

[0054] When the sliding frame 6 slides toward the door frame I3 and drives the cleaning brush plate 22 to move above the brush belt 20, the conveying roller 21 driven by the motor II27 drives the brush belt 20 to slide during the rotation. At the same time, the motor III29 drives the threaded rod 25 to rotate, and the threaded rod 25 drives the translation frame 26 to slide. At this time, the upper roller 28 slides and pushes the brush belt 20 at different positions, so that the brush belt 20 contacts the bottom surface of the cleaning brush plate 22, and the brush belt 20 slides relative to the cleaning brush plate 22. The dirt attached to the bottom surface of the cleaning brush plate 22 can be scraped off by the brush belt 20, that is, the cleaning brush plate 22 automatically cleans once it reciprocates once, thereby avoiding repeated contamination of the flat glass 5 by dirt, thereby greatly improving the cleaning effect of the flat glass 5.

[0055] In summary, when the sliding frame 6 of the present invention moves toward the door frame II4, the flushing nozzle 23 can be guided and sprayed to flush the flat glass 5. When the sliding frame 6 moves toward the door frame I3, the flushing nozzle 23 stops discharging water and the cleaning brush plate 22 contacts the flat glass 5 and performs unidirectional friction cleaning on it, thereby realizing the alternating spraying and cleaning, greatly improving the cleaning efficiency of the flat glass 5, and preventing the dirt attached to the cleaning brush plate 22 from moving back and forth relative to the flat glass 5 and causing secondary contamination and damage to the flat glass 5. The brush belt 20 of the present invention can rotate under the drive of the conveyor roller 21, and the translation frame 26 pushes the brush belt 20 at different positions when driving the top roller 28 to move, ensuring that the brush belt 20 contacts the bottom surface of the cleaning brush plate 22, and scraping and cleaning the dirt attached to the bottom surface of the cleaning brush plate 22, effectively improving the cleanliness of the cleaning brush plate 22, and significantly improving the cleaning effect of the flat glass 5.
