DETAILED DESCRIPTION

[0027] Embodiment 1: Figure 1 - Figure 5 As shown, an online automatic wiping roller device for a scraper roller comprises a trough body 1, an inner wall of the trough body 1 is provided with a mounting spindle 11, a scraper roller 2 is fixed to the mounting spindle 11 through a mounting seat 4, the mounting seat 4 is connected with a slide rod seat 8, a slide rod 9 is provided at one end of the slide rod seat 8 facing away from the mounting seat 4, the slide rod 9 is slidably connected with a cleaning device 12 for cleaning the scraper roller 2, and the outer end surface of the scraper roller 2 is provided with a driving mechanism for driving the cleaning device 12 to move back and forth.

[0028] Furthermore, two groups of mounting seats 4 are provided, which are respectively arranged on both sides of the inner wall of the tank body 1 .

[0029] When in use, the scraping roller 2 is used to scrape the coating material. After scraping, the cleaning device 12 moves back and forth to clean the surface of the scraping roller 2, effectively preventing the liquid from remaining on the surface of the scraping roller 2 and crystallizing to affect the coating quality, and at the same time avoiding safety issues caused by manual cleaning.

[0030] Embodiment 2: as Figure 1 - Figure 5 As shown, on the basis of embodiment 1, a driving rod 5 is fixedly connected to the middle part of the mounting seat 4, a driving internal gear 7 is provided at one end of the driving rod 5, the scraper roller 2 is provided with a scraper roller transmission gear 3 matched with the driving internal gear 7, and the driving mechanism includes a capstan 6, the capstan 6 is provided with two groups fixedly connected to the outer end surface of the trough body 1, a transmission belt 10 is pulled between the capstans 6, and the transmission belt 10 is fixedly connected to the end of the cleaning device 12 away from the scraper roller 2.

[0031] When in use, the driving rod 5 is connected to a driving source including but not limited to a motor, and drives the driving rod 5 to rotate. The driving rod 5 drives the scraper roller 2 to rotate by driving the internal gear 7 to engage with the scraper roller transmission gear 3. The rotation of the scraper roller 2 can improve the cleaning effect of the cleaning device 12 on it, and capstans 6 are provided at both ends of the trough body 1. By controlling the alternating rotation of the capstan 6, the transmission belt 10 can drive the cleaning device 12 to reciprocate along the surface of the slide rod 9, thereby driving the cleaning device 12 to reciprocate in contact with the surface of the scraper roller 2, thereby cleaning the surface of the scraper roller 2.

[0032] like Figure 1 - Figure 6 As shown, the cleaning device 12 includes a sliding seat 13 and a cleaning seat 16. The sliding seat 13 is slidably connected to the outer end surface of the slide rod 9. The cleaning seat 16 is elastically connected to the side of the cleaning device 12 that is in contact with the scraper roller 2 through an elastic rod 20. The cleaning seat 16 is provided with a fitting groove 18 that is compatible with the scraper roller 2, and a cleaning block 19 is provided on the inner wall of the fitting groove 18.

[0033] Furthermore, the cleaning block 19 is made of polytetrafluoroethylene.

[0034] When in use, the cleaning seat 16 is provided with a fitting groove 18 adapted to the scraper roller 2, and the cleaning block 19 elastically fits with the surface of the scraper roller 2 under the action of the elastic rod 20, and the sliding seat 13 is fixedly connected to the transmission belt 10. By controlling the rotation of the capstan 6, the sliding seat 13 is driven to reciprocate linearly along the slide rod 9, thereby driving the cleaning block 19 to reciprocate linearly along the surface of the scraper roller 2, thereby removing crystals or contaminants from the scraper roller 2 through friction.

[0035] like Figure 1 - Figure 7 As shown, the cleaning belt 17 is elastically connected to the middle of the fitting groove 18 , and the inner wall of the cleaning block 19 is provided with a pressing groove 23 matched with the cleaning belt 17 .

[0036] Furthermore, the thickness of the cleaning tape 17 is greater than the depth of the laminating groove 23 , and a plurality of cleaning tapes 17 may be provided, which are evenly spaced and distributed inside the laminating groove 18 .

[0037] During use, since the cleaning block 19 is in hard contact with the surface of the scraper roller 2, it is difficult for the cleaning block 19 to completely fit with the surface of the scraper roller 2 under the action of long-term friction, thereby affecting the cleaning effect of the cleaning block 19 on the scraper roller 2, and a cleaning belt 17 is provided. The cleaning belt 17 is elastically arranged inside the fitting groove 18. Under the action of the elastic force, the cleaning belt 17 will wrap the surface of the scraper roller 2, and with the movement of the sliding seat 13, the cleaning belt 17 will reciprocate along the surface of the scraper roller 2, so that the cleaning belt 17 cleans the surface of the scraper roller 2, and a pressing groove 23 is provided on the inner wall of the cleaning block 19, and the depth of the pressing groove 23 is lower than the thickness of the cleaning belt 17, so that the cleaning block 19 generates pressure on the cleaning belt 17 when fitting, thereby improving the cleaning effect of the cleaning belt 17 on the scraper roller 2.

[0038] like Figure 1 - Figure 8 and Fig.10 As shown, the cleaning belt 17 includes reinforcing ribs 37 and an adsorption layer 38. The adsorption layer 38 is elastically arranged in the middle of the bonding groove 18. There are multiple groups of reinforcing ribs 37, and the multiple groups of reinforcing ribs 37 are evenly embedded in the side where the adsorption layer 38 and the scraping roller 2 are bonded.

[0039] Furthermore, the reinforcement rib 37 is arranged in a direction perpendicular to the moving direction of the sliding seat 13 .

[0040] When in use, the structural strength of the cleaning belt 17 is improved by providing reinforcing ribs 37, while the cleaning effect on the scraper roller 2 is also improved. An adsorption layer 38 is also provided, which can absorb the residual cleaning liquid on the surface of the scraper roller 2, further improving the cleaning effect of the cleaning belt 17.

[0041] like Figure 1 - Figure 6 As shown, a driving wheel 22 is rotatably provided inside the sliding seat 13 , and the driving wheel 22 is rotatably adjusted on the outer end surface of the sliding rod 9 . A first thread groove 14 is provided between the driving wheel 22 and the sliding rod 9 , and the cleaning belt 17 is wound around the outer end surface of the driving wheel 22 .

[0042] When in use, a driving wheel 22 is provided inside the sliding seat 13, so that the sliding seat 13 can slide back and forth along the surface of the sliding rod 9, and the driving wheel 22 can be driven to rotate back and forth through the first threaded groove 14, and the cleaning belt 17 is wrapped around the outer surface of the driving wheel 22, so that the cleaning belt 17 can slide relatively inside the fitting groove 18, so that the sliding seat 13 reciprocates to clean the scraping roller 2, and the cleaning belt 17 itself is also moving, thereby improving the cleaning effect of the scraping roller 2 and avoiding excessive accumulation of pollutants on the cleaning belt 17.

[0043] like Figure 1-6As shown, a liquid storage box 21 is provided in the middle of the sliding seat 13, and a tensioning mechanism 15 is provided above the liquid storage box 21. The bottom of the tensioning mechanism 15 is elastically pressed against the surface of the cleaning belt 17. The tensioning mechanism 15 is used to press the cleaning belt 17 into the interior of the liquid storage box 21, and the interior of the liquid storage box 21 is filled with a filling medium 34.

[0044] Furthermore, the filling medium 34 is an organic solvent such as alcohol, and guide wheels 24 are symmetrically arranged inside the cleaning block 19 .

[0045] During use, the cleaning belt 17 is elastically pressed together by the tensioning mechanism 15, so that the cleaning belt 17 can always maintain a certain elastic tension inside the fitting groove 18, and part of the cleaning belt 17 is pressed into the liquid storage box 21. The filling medium 34 carried inside the liquid storage box 21 can dissolve and absorb the residual cleaning agent such as dichloromethane on the surface of the cleaning belt 17. At the same time, dichloromethane has a low boiling point and is relatively easy to evaporate. Traditionally, cleaning is performed by friction. Heat generated at the friction point will also cause rapid volatilization of dichloromethane, thereby causing pollution to the air and the working environment. Then, the adsorption layer 38 will also absorb part of the filling medium 34, which improves the cleaning effect of the adsorption layer 38 on the scraper roller 2. At the same time, the filling medium 34 inside the adsorption layer 38 can also cool down the cleaning belt 17 during friction cleaning to avoid excessive temperature.

[0046] like Figure 1 - Fig.11 As shown, the tensioning mechanism 15 includes a connecting plate 28, an adapting groove 29, a pressure wheel 30 and a rotating plate 31. The connecting plate 28 is elastically connected to the sliding seat 13. The rotating plate 31 is fixedly connected to both ends of the connecting plate 28. The pressure wheel 30 is rotatably connected between the rotating plates 31. The adapting groove 29 is opened on the outer end surface of the pressure wheel 30. The width of the adapting groove 29 is adapted to the pressure wheel 30.

[0047] When in use, the cleaning belt 17 is pressed together by the pressure wheel 30 and the cleaning belt 17, and the connecting plate 28 is elastically connected to the sliding seat 13. The tension of the cleaning belt 17 is controlled by controlling the size of its elastic force, and an adapter groove 29 is provided on the surface of the pressure wheel 30. The adapter groove 29 limits the cleaning belt 17 to avoid interference between multiple groups of cleaning belts 17 during transportation.

[0048] like Figure 1 - Fig.11 As shown, an adjustment plate 26 is slidably connected inside the sliding seat 13, and the adjustment plate 26 is connected to the adjustment knob 25 through a second threaded groove 27. The end of the adjustment knob 25 facing away from the adjustment plate 26 extends to the outer surface of the cleaning device 12. A plug-in plate 33 is provided at the bottom of the adjustment plate 26 and is telescopically sleeved inside the rotating plate 31. The adjustment plate 26 and the connecting plate 28 are elastically connected by an elastic member 32.

[0049] When in use, by rotating the adjusting knob 25, the adjusting plate 26 can be controlled to move inside the sliding seat 13, thereby compressing the elastic member 32 between the connecting plate 28 and the adjusting plate 26, thereby realizing the tension control of the cleaning belt 17. By controlling the tension of the cleaning belt 17, the cleaning force of the cleaning belt 17 can be adjusted.

[0050] like Figure 1 - Fig.12 As shown, a bottom rod 35 is provided at the bottom of the liquid storage box 21 , and the bottom rod 35 is arranged below the cleaning belt 17 . An extrusion protrusion 36 that fits the cleaning belt 17 is elastically connected to the top of the bottom rod 35 .

[0051] Furthermore, the contact area between the extrusion protrusion 36 and the cleaning belt 17 is arc-shaped, which reduces the wear on the cleaning belt 17.

[0052] When in use, the cleaning belt 17 is elastically pressed together by squeezing the protrusion 36 and the tensioning mechanism 15, so that the cleaning liquid adsorbed inside the adsorption layer 38 is discharged and dissolved into the filling medium 34. At the same time, the absorption amount of the filling medium 34 by the adsorption layer 38 can also be increased. The liquid storage box 21 can be connected to the liquid circulation waterway to monitor the solubility and temperature inside the filling medium 34.

[0053] Working principle: The scraping roller 2 is used to scrape the coating material. After scraping, the surface of the scraping roller 2 is cleaned by the reciprocating movement of the cleaning device 12, which effectively prevents the residual crystallization of liquid on the surface of the scraping roller 2 from affecting the coating quality. At the same time, it can avoid the safety problems caused by manual cleaning. The driving rod 5 is connected to a driving source including but not limited to a motor, etc., and drives the driving rod 5 to rotate. The driving rod 5 drives the scraping roller 2 to rotate by driving the internal gear 7 to mesh with the scraping roller transmission gear 3. The rotation of the scraping roller 2 can improve the cleaning effect of the cleaning device 12 on it, and the capstan 6 is provided at both ends of the tank body 1. By controlling the alternating rotation of the capstan 6, the transmission belt 10 can drive the cleaning device 12 to reciprocate along the surface of the sliding rod 9, thereby driving The cleaning device 12 reciprocates in accordance with the surface of the scraper roller 2 to clean the surface of the scraper roller 2. The cleaning seat 16 is provided with a fitting groove 18 adapted to the scraper roller 2. The cleaning block 19 elastically fits with the surface of the scraper roller 2 under the action of the elastic rod 20. The sliding seat 13 is fixedly connected to the transmission belt 10. The sliding seat 13 is driven to reciprocate linearly along the slide rod 9 by controlling the rotation of the capstan 6, thereby driving the cleaning block 19 to reciprocate linearly along the surface of the scraper roller 2, thereby removing crystals or contaminants on the scraper roller 2 through friction. Since the cleaning block 19 is in hard contact with the surface of the scraper roller 2, it is difficult for the cleaning block 19 to completely fit with the surface of the scraper roller 2 under the action of long-term friction, thereby affecting the cleaning block 19 on the scraper roller 2, a cleaning belt 17 is provided, and the cleaning belt 17 is elastically arranged inside the fitting groove 18. Under the action of the elastic force, the cleaning belt 17 will wrap the surface of the scraping roller 2, and with the movement of the sliding seat 13, the cleaning belt 17 reciprocates along the surface of the scraping roller 2, so that the cleaning belt 17 cleans the surface of the scraping roller 2, and a pressing groove 23 is provided on the inner wall of the cleaning block 19, and the depth of the pressing groove 23 is lower than the thickness of the cleaning belt 17, so that the cleaning block 19 generates pressure on the cleaning belt 17 when fitting, thereby improving the cleaning effect of the cleaning belt 17 on the scraping roller 2, and the structural strength of the cleaning belt 17 is improved by providing a reinforcing rib 37, and the cleaning effect on the scraping roller 2 can also be improved, and an adsorption layer 38 is also provided, which can adsorb the surface of the scraping roller 2 The residual cleaning liquid is absorbed to further improve the cleaning effect of the cleaning belt 17. By providing a driving wheel 22 inside the sliding seat 13, the sliding seat 13 can slide back and forth along the surface of the sliding rod 9 while the driving wheel 22 can be driven to rotate back and forth through the first thread groove 14. The cleaning belt 17 is wound around the outer surface of the driving wheel 22 so that the cleaning belt 17 can slide relatively inside the fitting groove 18. As a result, while the sliding seat 13 reciprocates to clean the scraping roller 2, the cleaning belt 17 itself is also moving, thereby improving the cleaning effect of the scraping roller 2 and avoiding excessive accumulation of pollutants on the cleaning belt 17. The cleaning belt 17 is elastically pressed by a tensioning mechanism 15, so that the cleaning belt 17 can always maintain a certain elastic tension inside the fitting groove 18.The cleaning belt 17 is partially pressed into the interior of the liquid storage box 21. The filling medium 34 carried inside the liquid storage box 21 can dissolve and absorb the residual cleaning agent such as dichloromethane on the surface of the cleaning belt 17. At the same time, dichloromethane has a low boiling point and is relatively easy to volatilize. Traditionally, cleaning is performed by friction. Heat generated at the friction point will also cause rapid volatilization of dichloromethane, thereby causing pollution to the air and the working environment. Then, the adsorption layer 38 will also absorb part of the filling medium 34, which improves the cleaning effect of the adsorption layer 38 on the scraper roller 2. At the same time, the filling medium 34 inside the adsorption layer 38 can also cool down the cleaning belt 17 during friction cleaning to avoid excessive temperature. The cleaning belt 17 is pressed by the clamping wheel 30 and the cleaning belt 17, and the connecting plate 28 is elastically connected to the sliding seat 13. The tension of the cleaning belt 17 can be controlled by controlling the size of its elastic force. The surface of the pressure wheel 30 is provided with an adapting groove 29, which limits the cleaning belt 17 to prevent multiple groups of cleaning belts 17 from interfering with each other during the conveying process. By rotating the adjusting knob 25, the adjusting plate 26 can be controlled to move inside the sliding seat 13, thereby compressing the elastic member 32 between the connecting plate 28 and the adjusting plate 26, thereby realizing the tension control of the cleaning belt 17. By controlling the tension of the cleaning belt 17, the cleaning force of the cleaning belt 17 can be adjusted. By squeezing the protrusion 36 and the tensioning mechanism 15 to elastically press the cleaning belt 17, the cleaning liquid adsorbed inside the adsorption layer 38 is discharged and dissolved into the filling medium 34. At the same time, the absorption amount of the filling medium 34 by the adsorption layer 38 can also be increased. The liquid storage box 21 can be connected to the liquid circulation waterway to monitor the solubility and temperature inside the filling medium 34.
