Detailed implementation manner

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0033] As Figures 1-7 shown, a squeegee assembly for a glass screen printing machine that is convenient for cleaning includes: a processing table 1, a cylinder 15, and a liquid sprayer 21. A controller 2 is fixedly connected to the side end of the processing table 1. A lifting plate 6 is fixedly connected to the side end of the controller 2. A control panel 7 is fixedly connected to the bottom end of the lifting plate 6. Two squeegees 9 are provided at the bottom end of the control panel 7. Side plates 8 are fixedly connected to both ends of the squeegee 9 respectively. The side plates 8 are rotatably connected to both ends of the control panel 7 respectively. The cylinder 15 is fixedly connected to the side end of the controller 2. A telescopic rod 17 is fixedly connected to the side end of the cylinder 15. A cleaning assembly is fixedly connected to the side end of the telescopic rod 17. A number of liquid sprayers 21 are provided and are fixedly connected to the top ends of the cleaning assembly respectively. When the glass screen printing machine is used up, it is necessary to clean the ink on the surface of the squeegee. At this time, the cylinder 15 operates, and the cylinder 15 moves the telescopic rod 17 towards the squeegee 9. The telescopic rod 17 drives the cleaning assembly to clean the ink on the surface of the squeegee 9. The cleaning assembly reciprocates along the surface of the squeegee 9, thereby achieving the effect of automatically cleaning the ink on the surface of the squeegee 9, avoiding the time-consuming and laborious phenomenon of the staff removing the squeegee 9 from the control panel 7 for cleaning, and further improving the working efficiency of automatically cleaning the squeegee 9. In the prior art, the two squeegees 9 respectively play the roles of leveling and recycling the ink. The two squeegees 9 can adjust the angle through an electrical system. When the cleaning assembly cleans the squeegee 9, the electrical system controls the side plate 8 to rotate, and the side plate 8 drives the squeegee 9 to rotate, so as to adjust the squeegee 9 and the bottom of the control panel 7 to be perpendicular, and then the cleaning assembly operates again to clean the perpendicular squeegee 9;

[0034] When the cleaning component cleans the ink on the surface of the squeegee 9, the liquid sprayer 21 operates. The liquid sprayer 21 feeds the stored cleaning agent into the cleaning component, and then sprays on both sides of the squeegee 9. The cleaning agent re-cleans the ink on the surface of the squeegee 9. The cleaning agent on the surface of the squeegee 9 facilitates the cleaning by the cleaning component. At the same time, the cleaning agent fed by the liquid sprayer 21 can clean the inside of the cleaning component, preventing ink from remaining on the cleaning component and affecting its secondary use.

[0035] In some specific embodiments, the controller 2 is provided with a storage chamber 16 through which it runs. The storage chamber 16 is used to store the cleaning component. The telescopic rod 17 runs through the storage chamber 16. When the cleaning component is not in use, the cylinder 15 controls the telescopic rod 17 to retract. The telescopic rod 17 drives the cleaning component to move to the storage chamber 16, so that the cleaning component can retract into the storage chamber 16. The cleaning component can be stored in the storage chamber 16 to prevent the cleaning component from affecting the operation of the squeegee 9 when the squeegee 9 is running. At the same time, it prevents the cleaning component from protruding and affecting the aesthetics of the equipment.

[0036] In some specific embodiments, the cleaning component includes a cleaning shell 10, a support platform 18, and a cleaning shaft 23. The support platform 18 is fixedly connected to the inner wall of the cleaning shell 10. The top of the cleaning shell 10 is fixedly connected to the liquid sprayer 21. A number of groups of cleaning shafts 23 are provided along the length and width directions of the cleaning shell 10 and are located on both sides of the squeegee 9 respectively. The upper and lower ends of the cleaning shaft 23 are rotatably connected to the cleaning shell 10. When the cleaning component operates, the cleaning component reciprocates along both sides of the squeegee 9. The cleaning shell 10 drives the support platform 18 to move. The cleaning shafts 23 on the cleaning shell 10 roll along the surface of the squeegee 9. On the one hand, the cleaning shafts 23 can remove the ink on the surface of the squeegee 9. At the same time, the squeegee 9 can absorb the ink and the cleaning agent, so as to ensure that the clean cleaning agent sprayed by the liquid sprayer 21 can perform a secondary cleaning on the squeegee 9.

[0037] In some specific embodiments, the support platform 18 is provided with a number of liquid inlet holes 19 that penetrate the top of the cleaning shell 10 along the height direction. A number of spray holes 20 are provided on the side end of the support platform 18. The number of liquid inlet holes 19 are equidistantly distributed along the length and width directions of the support platform 18 respectively. The liquid inlet holes 19 are in communication with the liquid sprayer 21, and the liquid inlet holes 19 are in communication with the spray holes 20. When the liquid sprayer 21 sprays the cleaning agent to clean the ink on the surface of the squeegee 9, the liquid sprayer 21 feeds the cleaning agent into the liquid inlet holes 19. The cleaning agent flows along the inner wall of the liquid inlet holes 19 and then sprays out at the spray holes 20. The spray holes 20 are located between the cleaning shafts 23 respectively. The cleaning agent cleans the ink on the surface of the squeegee 9. The cleaning agent and the ink can flow downward along the surface of the squeegee 9 and fall on the cleaning shell 10.

[0038] In some specific embodiments, a holding column 24 with a semi-circular cross-section is provided at the side end of the cleaning shaft 23. The holding column 24 is fixedly connected to the inner wall of the support platform 18. When the cleaning shaft 23 absorbs ink and cleaning agent for a long time, the cleaning shaft 23 can be made of sponge. At this time, the cleaning shaft 23 cannot absorb the ink and cleaning agent on the surface of the squeegee 9. Therefore, when the cleaning shaft 23 rotates, the cleaning shaft 23 can come into contact with the holding column 24, and the holding column 24 squeezes the cleaning shaft 23. The part where the holding column 24 and the cleaning shaft 23 are squeezed can discharge the ink and cleaning agent. The discharged cleaning agent and ink flow to the bottom of the cleaning housing 10. When the ink on the surface of the squeegee 9 is cleaned, at this time, the cleaning shaft 23 continues to absorb the cleaning agent, and the cleaning agent cleans the ink in the cleaning shaft 23, thus ensuring the cleanliness of the cleaning assembly.

[0039] In some specific embodiments, a plurality of liquid outlet holes 25 are formed at the bottom of the cleaning housing 10. The plurality of liquid outlet holes 25 are respectively located at the side end of the cleaning shaft 23. When the cleaning agent flows to the bottom of the cleaning housing 10 with the ink, the cleaning agent discharges with the ink from the liquid outlet holes 25, thereby achieving the effect of discharging the ink and cleaning agent from the cleaning assembly.

[0040] In some specific embodiments, a recycling box 11 is fixedly connected to the bottom end of the cleaning assembly. A wire mesh plate 5 is provided at the bottom of the recycling box 11. The wire mesh plate 5 is located at the side end of the controller 2. When the cleaning agent and the ink flow out from the liquid outlet holes 25, the cleaning agent flows into the recycling box 11 with the ink. The recycling box 11 can recycle the cleaning agent and the ink, thereby avoiding the phenomenon that the cleaning agent drops on the processing table 1 with the ink, and further achieving the effect of protecting the cleanliness of the equipment.

[0041] In some specific embodiments, clamping plates 3 are fixedly connected to both ends of the wire mesh plate 5. A mover 4 is fixedly connected to the side end of the clamping plate 3. The side end of the mover 4 is slidably connected to the controller 2. When the clamping plate 3 is used up, the mover 4 slides downward on the controller 2. The mover 4 drives the clamping plate 3 to move downward, and the clamping plate 3 drives the wire mesh plate 5 to move downward.

[0042] In some specific embodiments, an absorption component for cleaning the wire mesh plate 5 is fixedly connected to the bottom end of the recycling box 11. The absorption component includes: a servo motor 12, a rotating shaft 13, and an absorption plate 14. The top end of the servo motor 12 is fixedly connected to the recycling box 11. The upper and lower ends of the rotating shaft 13 are respectively fixedly connected to the servo motor 12 and the absorption plate 14. When the cleaning component cleans the scraper 9, the recycling box 11 drives the absorption component to clean the ink remaining on the surface of the wire mesh plate 5. When the cleaning component operates, the servo motor 12 operates. The servo motor 12 drives the rotating shaft 13 to rotate, and the rotating shaft 13 drives the absorption plate 14 to rotate. The absorption plate 14 absorbs and cleans the ink remaining on the surface of the wire mesh plate 5, thereby realizing the cleaning of the ink remaining on the surface of the wire mesh plate 5 and avoiding the effect of the staff removing and cleaning the wire mesh plate 5.

[0043] The above has described several embodiments of the present invention in detail, but the embodiments of the present invention are not limited thereto and cannot be considered as defining the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the present invention application should still fall within the scope covered by the patent of the present invention.
