Description

Technical Field

[0001] The invention belongs to the technical field of ceramic cleaning devices, and in particular relates to a fully automatic cleaning device for roller-coated ceramic sheets. Background Art

[0002] Ceramic drum lagging is a special treatment technology on the drum surface. By sticking high wear-resistant rubber on the drum surface and embedding ceramic sheets on the rubber composite plate, it has good wear resistance and is especially suitable for use in extremely harsh environments such as muddy, humid, and high wear. Therefore, it can improve the performance and service life of the drum.

[0003] The ceramic sheets used are usually made by powder stamping, but there is a lot of powder adhering to the prepared ceramic sheets, and the stamping process will cause burrs on the edges of the ceramic sheets. Therefore, the prepared ceramic sheets need to be cleaned, and the existing cleaning equipment usually uses a nozzle to spray the ceramic sheets, and the nozzle usually sprays over a large area and a wide range, resulting in poor cleaning effect and low cleaning efficiency when the ceramic sheets are cleaned in this way. For this reason, a fully automatic cleaning device for drum-coated ceramic sheets is proposed. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a fully automatic cleaning device for drum-coated ceramic sheets that can overcome the above problems or at least partially solve the above problems.

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: a fully automatic cleaning device for roller-coated ceramic sheets, comprising: a lower propulsion roller, an upper propulsion roller, a lower cleaning roller and an upper cleaning roller which are arranged to rotate up and down, the lower propulsion roller, the upper propulsion roller and the lower cleaning roller, and the upper cleaning roller are horizontally arranged in multiple groups, the lower propulsion roller and the upper propulsion roller rotate relative to each other to clamp the ceramic sheet to move the ceramic sheet, the lower cleaning roller rotates relative to the lower propulsion roller, and the upper cleaning roller rotates relative to the upper propulsion roller to generate relative friction with the moving ceramic sheet; a triangular narrow area is located between the ceramic sheet, the upper propulsion roller and the upper cleaning roller multiple groups of liquid spray channels are arranged on the upper pushing roller, each group of the liquid spray channels is provided with multiple liquid spray channels, and are circumferentially opened in the upper pushing roller; during the rotation of the lower pushing roller, the upper pushing roller, the lower cleaning roller, and the upper cleaning roller, when the liquid spray channel is opened, the second liquid spray section of the liquid spray channel forms an acute angle with the upper surface of the ceramic sheet for flushing the ceramic sheet, when the liquid spray channel is opened, the second liquid spray section of the liquid spray channel is located in the triangular narrow area, and the second liquid spray section faces the ceramic sheet, when the liquid spray channel is opened, the second liquid spray section of the liquid spray channel is inclined toward the previous upper pushing roller for spraying the previous upper pushing roller.

[0006] Preferably, the upper pushing roller is meshed with the lower pushing roller and the upper cleaning roller, and the lower cleaning roller is meshed with the upper cleaning roller and the lower pushing roller, so as to limit the lower pushing roller, the upper pushing roller, the lower cleaning roller and the upper cleaning roller.

[0007] Preferably, a first retaining ring is fixedly connected at equal intervals on the outer circumference of the lower pushing roller, and a first limiting groove and a second limiting groove are respectively provided at equal intervals on the outer circumference of the upper pushing roller and the outer circumference of the lower cleaning roller, and the first retaining ring is respectively located in the first limiting groove and the second limiting groove; a second retaining ring is fixedly connected at equal intervals on the outer circumference of the upper cleaning roller, and the second retaining ring is located in the first limiting groove.

[0008] Furthermore, a plurality of groups of liquid spray channels are opened on the outer circumference of the lower pushing roller, and each group of the liquid spray channels has a plurality of liquid spray channels and is opened circumferentially in the lower pushing roller. When the ceramic sheet passes through the lower pushing roller, and the second liquid spray section of the liquid spray channel on the lower pushing roller forms an acute angle with the ceramic sheet, the liquid spray channel opens.

[0009] Furthermore, a grinding ring is embedded in the side wall of the second retaining ring to clean the edges of the ceramic sheet.

[0010] Furthermore, a grinding strip is provided on the circumference of the outer circumference of the upper cleaning roller between adjacent second retaining rings. The grinding strip is in the shape of a long strip and has a length the same as the spacing between adjacent second retaining rings, so as to clean the upper surface of the ceramic sheet.

[0011] Preferably, grinding strips are circumferentially arranged on the outer circumference of the upper cleaning roller and the outer circumference of the lower cleaning roller.

[0012] Furthermore, the grinding strips on the outer circumference of the upper cleaning roller and the lower cleaning roller are arranged in an interval shape, and the grinding strips are arranged in a staggered manner on the circumference, and form an I-shaped guide groove.

[0013] Preferably, a switch assembly is further included to control the opening and closing of the spray channel, the switch assembly includes a sleeve, a sliding rod is slidably connected in the sleeve, a tension spring is connected between the end of the sliding rod and the sleeve, a connecting rod is connected to the end of the sliding rod, a plug rod is fixedly connected to the connecting rod, the plug rod corresponds to the first spray section of the spray channel, and the connecting rod pulls the plug rod to disengage from the first spray section by pushing the sliding rod.

[0014] A fully automatic cleaning method for a drum-coated ceramic sheet comprises the following steps:

[0015] S1, feeding the ceramic sheets one by one between the lower push roller, the upper push roller, the lower cleaning roller and the upper cleaning roller through the feed conveyor belt;

[0016] S2, spraying water on the ceramic sheet for cleaning and trimming through the liquid spraying channels on the lower and upper push rollers;

[0017] S3. After cleaning, the ceramic pieces are sent out through a discharging conveyor belt.

[0018] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art: when cleaning the ceramic sheet, the present invention can form a tangential angle with the surface of the ceramic sheet through the liquid spray channel to spray liquid for flushing, and the liquid spray channel sprays liquid into the triangular narrow area to flush the ground and polished ceramic sheet again and replenish the cleaning liquid for the next grinding and polishing. When the liquid spray channel sprays liquid in the triangular narrow area, it will cooperate with the area restriction of the triangular narrow area, so that when the cleaning liquid is sprayed, it can not only flush the ceramic sheet, but also make the cleaning liquid splash when sprayed in the triangular narrow area, which can The powder remaining on the ceramic sheet is washed away to avoid damage to the surface of the ceramic sheet when it is ground by the grinding bar. Secondly, the splashing cleaning liquid can also wash the adjacent upper propulsion roller and upper cleaning roller to wash the upper propulsion roller and the upper cleaning roller to keep them clean, and wash away the ceramic powder mixed between the grinding bars, further improving the washing, grinding and polishing effects of the ceramic sheet. In addition, the change of the spray channel can form a spraying effect on the surface of the previous upper propulsion roller, which enables the device to wash each ceramic sheet in a targeted manner, so that the cleaning effect and cleaning efficiency are better;

[0019] When the ceramic sheet moves to between the lower push roller and the upper push roller located on the right side of the lower cleaning roller, the liquid spraying channels on the upper push roller and the lower push roller will not only spray the cleaning liquid onto the upper and lower surfaces of the ceramic sheet, but also splash the cleaning liquid onto the lower cleaning roller and the upper cleaning roller located on the left side, thereby effectively washing the lower cleaning roller and the upper cleaning roller;

[0020] At the same time, since an I-shaped guide groove is formed between the grinding strips on the lower cleaning roller and the upper cleaning roller, the sprayed cleaning liquid can increase the flushing area of ​​the lower cleaning roller and the upper cleaning roller through the I-shaped guide groove, thereby preventing ceramic powder from adhering to the lower cleaning roller and the upper cleaning roller, causing the powder to leave scratches on the ceramic sheet when the lower cleaning roller and the upper cleaning roller rub against the surface of the ceramic sheet.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0037] Example 1: Reference Figure 1-Figure 11, a fully automatic cleaning device for drum-coated ceramic sheets, comprising: a lower propulsion roller 11, an upper propulsion roller 12, a lower cleaning roller 13, and an upper cleaning roller 14 that are arranged to rotate up and down, all of which are rotatably connected in a water tank 1, the water tank 1 is used to carry the lower propulsion roller 11, the upper propulsion roller 12, the lower cleaning roller 13, and the upper cleaning roller 14, and to receive the cleaning liquid sprayed from the liquid spray channel 127, the water tank 1 is installed in a cabinet 6 to prevent the cleaning liquid from splashing out, the lower propulsion roller 11, the upper propulsion roller 12, the lower cleaning roller 13, and the upper cleaning roller 14 are horizontally arranged in multiple groups, the lower propulsion roller 11 and the upper propulsion roller 12 rotate relative to each other to clamp the ceramic sheet 10 to move the ceramic sheet 10, the lower cleaning roller 13 rotates relative to the lower propulsion roller 11, and the upper cleaning roller 14 rotates relative to the upper propulsion roller 12 to generate relative friction with the moving ceramic sheet 10; triangular narrow The narrow area 100 is located between the ceramic sheet 10, the upper propulsion roller 12, and the upper cleaning roller 14; a plurality of groups of liquid spraying channels 127 are arranged on the upper propulsion roller 12, and each group of liquid spraying channels 127 is provided with five liquid spraying channels, and the liquid spraying channels 127 are circumferentially opened in the upper propulsion roller 12; during the rotation of the lower propulsion roller 11, the upper propulsion roller 12, the lower cleaning roller 13, and the upper cleaning roller 14, when the liquid spraying channel 127 is opened, the second liquid spraying section 1272 of the liquid spraying channel 127 forms an acute angle with the upper surface of the ceramic sheet 10, so as to rinse the ceramic sheet 10; when the liquid spraying channel 127 is opened, the second liquid spraying section 1272 of the liquid spraying channel 127 is located in the triangular narrow area 100, and the second liquid spraying section 1272 faces the ceramic sheet 10; when the liquid spraying channel 127 is opened, the second liquid spraying section 1272 of the liquid spraying channel 127 is inclined toward the previous upper propulsion roller 12, so as to spray the previous upper propulsion roller 12;

[0038] The upper push roller 12 is meshed with the lower push roller 11 and the upper cleaning roller 14, and the lower cleaning roller 13 is meshed with the upper cleaning roller 14 and the lower push roller 11 to limit the lower push roller 11, the upper push roller 12, the lower cleaning roller 13 and the upper cleaning roller 14 to avoid the position change caused by the axial position movement of one of the lower push rollers 11, the upper push roller 12, the lower cleaning roller 13 or the upper cleaning roller 14, which causes the ceramic sheet 10 to pass through the lower push roller 11, the upper push roller 12, the lower cleaning roller 13, the upper cleaning roller 14. The problem of poor cleaning effect may occur due to position change when the upper propulsion roller 12 is engaged with the lower propulsion roller 11 and the upper cleaning roller 14, and the lower cleaning roller 13 is engaged with the upper cleaning roller 14 and the lower propulsion roller 11, so that the lower propulsion roller 11, the upper propulsion roller 12, the lower cleaning roller 13 or the upper cleaning roller 14 can be further limited and mutually restricted, thereby preventing one of the lower propulsion roller 11, the upper propulsion roller 12, the lower cleaning roller 13 or the upper cleaning roller 14 from shifting in position after long-term use;

[0039] A first retaining ring 111 is fixedly connected to the outer periphery of the lower propulsion roller 11 at equal intervals, and a first limiting groove 128 and a second limiting groove 131 are respectively opened at equal intervals on the outer periphery of the upper propulsion roller 12 and the outer periphery of the lower cleaning roller 13, and the first retaining ring 111 is respectively located in the first limiting groove 128 and the second limiting groove 131; a second retaining ring 141 is fixedly connected to the outer periphery of the upper cleaning roller 14 at equal intervals, and the second retaining ring 141 is located in the first limiting groove 128;

[0040] A grinding ring 142 is embedded in the side wall of the second retaining ring 141 to clean the edges of the ceramic sheet 10;

[0041] A grinding strip 143 is provided on the circumference of the outer circumference of the upper cleaning roller 14 between the adjacent second retaining rings 141. The grinding strip 143 is in the shape of a long strip, and its length is the same as the distance between the adjacent second retaining rings 141, and is used to clean the upper surface of the ceramic sheet 10;

[0042] It also includes a switch assembly for controlling the opening and closing of the liquid spraying channel 127. The switch assembly includes a sleeve 122. A mounting hole 121 is provided on the outer circumference of the upper propulsion roller 12. The mounting hole 121 is located in the first limiting groove 128 of the upper propulsion roller 12. The sleeve 122 is threadedly connected to the mounting hole 121, so as to facilitate installation and disassembly. A sliding rod 123 is slidably connected in the sleeve 122. A tension spring 124 is connected between the end of the sliding rod 123 and the sleeve 122. A connecting rod 125 is connected to the end of the sliding rod 123. A plug rod 126 is fixedly connected to the connecting rod 125. The plug rod 126 corresponds to the first liquid spraying section 1271 of the liquid spraying channel 127. By pushing the sliding rod 123, the connecting rod 125 pulls the plug rod 126 to disengage from the first liquid spraying section 1271.

[0043] A gear 144 is installed at one end of the lower cleaning roller 13 and the upper cleaning roller 14. The gears 144 on the lower cleaning roller 13 and the upper cleaning roller 14 are meshed to make the lower cleaning roller 13 and the upper cleaning roller 14 rotate relative to each other. The lower cleaning roller 13 and the upper cleaning roller 14 are driven to rotate by a motor, and the motor speed is adjustable. In this device, the motor speed is slow, so that the single opening time of the liquid spray channel 127 is long, and more liquid can be sprayed out to improve the cleaning effect of the ceramic sheet 10, or the motor is fast, so that the single opening time of the liquid spray channel 127 is short, and the amount of cleaning liquid is saved when the cleaning is satisfied;

[0044] The multiple lower push rollers 11 and the multiple upper push rollers 12 are connected by synchronous belts 4 to achieve synchronous and same-speed rotation. The connecting pipe 5 for pumping the cleaning liquid into the cavity in the upper push roller 12 is rotatably sleeved at both ends of the upper push roller 12. A sealing ring is provided at the rotating sleeve to prevent water leakage.

[0045] Furthermore, a feed conveyor belt 2 and a discharge conveyor belt 3 are provided, which are respectively arranged on both sides. The outer walls of the feed conveyor belt 2 and the discharge conveyor belt 3 are respectively provided with a first limit strip 21 and a second limit strip 31 at equal intervals to limit and guide the ceramic sheet 10 to be cleaned. The feed conveyor belt 2 and the discharge conveyor belt 3 are respectively driven to rotate by a motor;

[0046] When in use, the ceramic sheet 10 to be cleaned is sequentially placed in the area between the adjacent first limiting strips 21 of the feed conveyor belt 2, and the feed conveyor belt 2 transports the ceramic sheet 10 between the lower push roller 11 and the upper push roller 12, and the relatively rotating lower push roller 11 and upper push roller 12 clamp the ceramic sheet 10. During the clamping process, the first retaining ring 111 on the lower push roller 11 contacts the sliding rod 123 in the first limiting groove 128 of the upper push roller 12, and pushes the sliding rod 123 to retract into the sleeve 122, so that the plug rod 12 6 is separated from the first spray section 1271 of the spray channel 127. At this time, the cleaning liquid in the cavity of the upper propulsion roller 12 passes through the spray channel 127 and is sprayed onto the ceramic sheet 10 at a tangential angle, so that the ceramic sheet 10 is rinsed. Moreover, since the second spray section 1272 of the spray channel 127 forms an acute angle with the surface of the ceramic sheet 10, that is, a tangential angle is formed, the cleaning liquid sprayed from the spray channel 127 can powerfully and specifically rinse the ceramic sheet 10, so that water can be saved and the cleaning liquid can be specifically rinsed;

[0047] When the ceramic sheet 10 continues to move in the forward direction, it reaches between the relatively rotating lower cleaning roller 13 and the upper cleaning roller 14. Since the lower cleaning roller 13 rotates relatively with the lower propulsion roller 11, and the upper cleaning roller 14 rotates relatively with the upper propulsion roller 12, the lower cleaning roller 13 and the upper cleaning roller 14 will produce relative friction on the ceramic sheet 10, and when the second retaining ring 141 on the upper cleaning roller 14 pushes the sliding rod 123, the liquid spraying channel 127 on the upper propulsion roller 12 will spray the cleaning liquid into the triangular narrow area 100 (refer to Figure 7 ), and the triangular narrow area 100 is located between the upper propulsion roller 12, the ceramic sheet 10, and the upper cleaning roller 14, so the area of ​​this area is small and the shielding area is large. Therefore, when the spray channel 127 sprays the cleaning liquid into the triangular narrow area 100, it can effectively avoid the splashing of the cleaning liquid, so that the area of ​​the ceramic sheet 10 covered by the cleaning liquid is increased, which makes the lower cleaning roller 13 and the upper cleaning roller 14 further improve the cleaning effect of the ceramic sheet 10 when rubbing the ceramic sheet 10, and the relatively rotating lower cleaning roller 13 and the upper cleaning roller 14 also have the effect of grinding and polishing the ceramic sheet 10, and the cleaning liquid sprayed into the triangular narrow area 100 by the spray channel 127 can make it have sufficient wetness during the grinding and polishing process, and can spray the cleaning liquid again before grinding and polishing, and the grinding ring 142 can also trim the burrs on both sides of the ceramic sheet 10;

[0048] Since the lower push roller 11, the upper push roller 12, the lower cleaning roller 13, and the upper cleaning roller 14 are provided in multiple groups and arranged horizontally, the ceramic sheet 10 can be rinsed, ground, and polished multiple times, further improving the cleaning effect of the ceramic sheet 10;

[0049] by Figure 6 Taking the perspective as an example, when the slide bar 123 on the upper propulsion roller 12 on the right side of the upper cleaning roller 14 contacts the second retaining ring 141 on the upper cleaning roller 14, the liquid spraying channel 127 sprays the cleaning liquid, and the second liquid spraying section 1272 of the liquid spraying channel 127 is tilted toward the upper propulsion roller 12 on the left side of the upper cleaning roller 14 at this time. At this time, the sprayed cleaning liquid will be sprayed on the upper propulsion roller 12 on the left side to clean the upper propulsion roller 12, so as to prevent the powder on the ceramic sheet 10 from adhering to the upper propulsion roller 12, causing damage to the ceramic sheet 10 when the ceramic sheet 10 is clamped;

[0050] It should be understood that when the cleaned ceramic sheet 10 is embedded in the rubber composite board, one side of the ceramic sheet 10 is adhered to the rubber composite board, so the quality of this side is not required.

[0051] It should be noted that the rotation speed and friction force of the lower propulsion roller 11 and the upper propulsion roller 12 are greater than the lower cleaning roller 13 and the upper cleaning roller 14, so as to avoid the relative rotation of the lower cleaning roller 13 and the upper cleaning roller 14, which may cause the ceramic sheet 10 to be unable to move forward normally.

[0052] After cleaning, the ceramic sheet 10 is moved to the discharge conveyor belt 3 to complete cleaning. The lower push roller 11, the upper push roller 12, the lower cleaning roller 13, and the upper cleaning roller 14 in the device are meshed and connected with each other, so displacement can be effectively avoided, and the guide groove 112 formed between the first retaining ring 111 can effectively guide and limit the ceramic sheet 10, so that the ceramic sheet 10 after cleaning can be neatly moved to the discharge conveyor belt 3, which is convenient for the subsequent suction cup manipulator to transfer the ceramic sheet 10, or convenient for manual sorting;

[0053] Therefore, when cleaning the ceramic sheet 10, the device can form a tangential angle with the surface of the ceramic sheet 10 through the spray channel 127 to spray liquid for flushing, and the spray channel 127 can spray liquid into the triangular narrow area 100 to flush the ground and polished ceramic sheet 10 again and replenish the cleaning liquid, and can also form an effect of spraying the surface of the previous upper push roller 12 through the change of the spray channel 127, so that the device can flush each ceramic sheet 10 in a targeted manner, so that the cleaning effect and cleaning efficiency are better.

[0054] Example 2: Reference Fig.12 , Fig.13, a fully automatic cleaning device for roller-coated ceramic sheets, which is basically the same as Example 1, and further: a plurality of groups of liquid spraying channels 127 are provided on the outer circumference of the lower propulsion roller 11, each group of liquid spraying channels 127 has a plurality of liquid spraying channels and is circumferentially provided in the lower propulsion roller 11, when the ceramic sheet 10 passes through the lower propulsion roller 11, and the second liquid spraying section 1272 of the liquid spraying channel 127 on the lower propulsion roller 11 forms an acute angle with the ceramic sheet 10, the liquid spraying channel 127 is opened;

[0055] Grinding strips 143 are circumferentially arranged on the outer circumference of the upper cleaning roller 14 and the outer circumference of the lower cleaning roller 13;

[0056] The grinding strips 143 on the outer circumference of the upper cleaning roller 14 and the lower cleaning roller 13 are arranged in an interval shape, and the grinding strips 143 are arranged in a staggered manner on the circumference, and form an I-shaped guide groove 1430;

[0057] It also includes a switch assembly for controlling the opening and closing of the liquid spraying channel 127. The switch assembly includes a sleeve 122. A mounting hole 121 is provided on the outer circumference of the lower propulsion roller 11. The mounting hole 121 and the liquid spraying channel 127 are both located between adjacent first retaining rings 111. The sleeve 122 is threadedly connected to the mounting hole 121, thereby facilitating installation and disassembly. A slide rod 123 is slidably connected in the sleeve 122. A tension spring 124 is connected between the end of the slide rod 123 and the sleeve 122. A connecting rod 125 is connected to the end of the slide rod 123. A plug rod 126 is fixedly connected to the connecting rod 125. The plug rod 126 corresponds to the first liquid spraying section 1271 of the liquid spraying channel 127. By pushing the slide rod 123, the connecting rod 125 pulls the plug rod 126 to disengage from the first liquid spraying section 1271.

[0058] When the ceramic sheet 10 is clamped by the lower propulsion roller 11 and the upper propulsion roller 12, the ceramic sheet 10 squeezes the slide bar 123, causing the slide bar 123 to retract into the sleeve 122, thereby causing the plug rod 126 to separate from the first spray section 1271 of the spray channel 127, so that the cleaning liquid in the cavity of the lower propulsion roller 11 is sprayed out from the spray channel 127, and at this time, the second spray section 1272 of the spray channel 127 also forms an acute angle with the surface of the ceramic sheet 10, that is, a tangential angle is formed, which can further improve the flushing and cleaning effect and cleaning efficiency of the ceramic sheet 10;

[0059] by Fig.12 Taking the perspective as an example, when the ceramic sheet 10 moves between the lower pushing roller 11 and the upper pushing roller 12 located on the right side of the lower cleaning roller 13, the liquid spraying channel 127 on the upper pushing roller 12 and the lower pushing roller 11 will not only spray the cleaning liquid onto the upper and lower surfaces of the ceramic sheet 10, but also splash the cleaning liquid onto the lower cleaning roller 13 and the upper cleaning roller 14 located on the left side, thereby effectively washing the lower cleaning roller 13 and the upper cleaning roller 14;

[0060] At the same time, since an I-shaped guide groove 1430 is formed between the grinding strips 143 on the lower cleaning roller 13 and the upper cleaning roller 14, the sprayed cleaning liquid can increase the area of ​​the lower cleaning roller 13 and the upper cleaning roller 14 through the I-shaped guide groove 1430, thereby preventing the lower cleaning roller 13 and the upper cleaning roller 14 from being adhered to ceramic powder, causing the lower cleaning roller 13 and the upper cleaning roller 14 to leave scratches on the ceramic sheet 10 when the lower cleaning roller 13 and the upper cleaning roller 14 rub against the surface of the ceramic sheet 10;

[0061] Therefore, in this embodiment, the device can further improve the cleaning effect and cleaning efficiency of the ceramic sheet 10 .

[0062] Furthermore, end covers 120 are installed at both ends of the lower propulsion roller 11 and the upper propulsion roller 12. After removing the end covers 120, the interior of the cavities of the lower propulsion roller 11 and the upper propulsion roller 12 can be easily observed.

[0063] Example 3: Reference Figure 1-Figure 13 , a fully automatic cleaning method for a drum-coated ceramic sheet, comprising the following steps:

[0064] S1, feeding the ceramic sheets 10 one by one into the space between the lower pushing roller 11, the upper pushing roller 12, the lower cleaning roller 13, and the upper cleaning roller 14 through the feeding conveyor belt 2;

[0065] S2, spraying water on the ceramic sheet 10 for cleaning and trimming through the liquid spraying channels 127 on the lower propulsion roller 11 and the upper propulsion roller 12;

[0066] S3, after cleaning, the ceramic sheet 10 is sent out through the discharge conveyor belt 3.

[0067] The present invention can form a tangential angle with the surface of the ceramic sheet 10 through the liquid spray channel 127 to spray liquid when cleaning the ceramic sheet 10, and the liquid spray channel 127 sprays liquid into the triangular narrow area 100 to rinse the ground and polished ceramic sheet 10 again and replenish the cleaning liquid, and can also form a spray effect on the surface of the previous upper propulsion roller 12 through the change of the liquid spray channel 127, so that the device can specifically rinse each ceramic sheet 10, so that the cleaning effect and cleaning efficiency are better;

[0068] When the ceramic sheet 10 moves to between the lower pushing roller 11 and the upper pushing roller 12 located on the right side of the lower cleaning roller 13, the liquid spraying channels 127 on the upper pushing roller 12 and the lower pushing roller 11 will not only spray the cleaning liquid onto the upper and lower surfaces of the ceramic sheet 10, but also splash the cleaning liquid onto the lower cleaning roller 13 and the upper cleaning roller 14 located on the left side, thereby effectively washing the lower cleaning roller 13 and the upper cleaning roller 14;

[0069] At the same time, since an I-shaped guide groove 1430 is formed between the grinding strips 143 on the lower cleaning roller 13 and the upper cleaning roller 14, the sprayed cleaning liquid can increase the flushing area of ​​the lower cleaning roller 13 and the upper cleaning roller 14 through the I-shaped guide groove 1430, thereby preventing ceramic powder from adhering to the lower cleaning roller 13 and the upper cleaning roller 14, causing the powder to leave scratches on the ceramic sheet 10 when the lower cleaning roller 13 and the upper cleaning roller 14 rub against the surface of the ceramic sheet 10.

[0070] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with the present invention can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
