Description

Technical Field

[0001] The present invention relates to the technical field of plate cleaning, and in particular to an automatic cleaning device and method for plate production. Background Art

[0002] Cleaning the plate after processing can effectively remove stains and residues on the surface, extend the service life of the plate, and improve the efficiency of subsequent processes. Ultrasonic cleaning is an efficient cleaning method that uses the high-frequency vibration and cavitation effect of ultrasound to penetrate into the tiny gaps on the surface of the plate and effectively remove dirt. It is particularly suitable for removing oil, cutting chips, light stains and tiny particles on the surface of the plate.

[0003] In the prior art, a dedicated ultrasonic cleaning device is generally used to clean the plate, such as a plate water cleaning device disclosed in a patent application document with application publication number CN111842322A. The device includes a body, a cleaning chamber is provided at the bottom of the inner side of the body, a drain valve and a water inlet valve are provided on the sides of the cleaning chamber, and an ultrasonic transducer is installed in the cleaning chamber. Both sides of the body are provided with through openings connected to the cleaning chamber, a driving motor is installed on one side of the body, conveying roller groups are provided on both sides of the body, and the two conveying roller groups are arranged on the lower side of the through opening, a hot air blower is installed on the upper side of the body, and the air outlet of the hot air blower is connected to the inner side of the body through an air pipe, and a heat insulation film is provided on the inner side of each through opening, and a first conveyor belt and a second conveyor belt are relatively inclinedly installed on the inner side of the body, one end of the first conveyor belt is adjacent to the upper side of one end of the second conveyor belt, and a rotatable cleaning brush is provided on the upper side of the first conveyor belt.

[0004] During the operation of the equipment, the plate enters the cleaning chamber from the conveyor roller group on the left, and then is ultrasonically cleaned while being conveyed on the first conveyor belt and the second conveyor belt, and then moves to the conveyor roller group on the right to leave the cleaning chamber. Although the equipment can improve efficiency and reduce labor costs, the ultrasonic transducer in the equipment is installed at the bottom of the cleaning chamber. During the cleaning process, the ultrasonic transducer is far away from the plate, and only the bottom surface of the plate can face the ultrasonic transducer, while the top surface of the plate is always facing away from the ultrasonic transducer, resulting in poor ultrasonic cleaning effect on the top surface of the plate. At the same time, during the conveying process, the bottom surface of the plate is always in contact with the conveyor belt, and the part of the bottom surface of the plate that is blocked by the conveyor belt and not exposed is difficult to clean. Summary of the invention

[0005] The present invention provides an automatic cleaning device for plate production, so as to solve the technical problems in the prior art that when plate cleaning equipment is used to clean the plate, the ultrasonic cleaning effect on the top surface of the plate is poor and the part of the bottom surface of the plate blocked by the conveyor belt is difficult to clean.

[0006] The present invention also provides an automatic cleaning method for the production of plates. The plate can be cleaned by using the method to improve the cleaning effect and make the plate cleaned more thoroughly.

[0007] In order to solve the above problems, the present invention provides an automatic cleaning device for plate production, which adopts the following technical solutions:

[0008] An automatic cleaning device for plate production, comprising a frame, two groups of conveyor rollers, a first conveyor belt assembly, a second conveyor belt assembly and an ultrasonic generator, a cleaning chamber is provided in the middle of the frame, the two groups of conveyor rollers are mounted on the frame and located on the left and right sides above the cleaning chamber, the first conveyor belt assembly and the second conveyor belt assembly are sequentially arranged in the cleaning chamber from left to right and form a V-shaped structure with an opening facing upward, the left end of the first conveyor belt assembly is connected to the lower side of the right end of the conveyor roller assembly on the left side, the right end of the second conveyor belt assembly is connected to the lower side of the left end of the conveyor roller assembly on the right side, and the ultrasonic generator is installed in the cleaning chamber;

[0009] It also includes a flipping mechanism located at the bottom of the V-shaped groove of the V-shaped structure, the flipping mechanism includes a flap structure extending forward and backward and rotatably mounted on the frame body, and a motor drivingly connected to the flap structure, the flap structure is provided with a receiving groove for receiving the plate on the first conveyor belt assembly, and the motor is used to drive the flap structure to rotate so as to flip the plate received by the flap structure from the first conveyor belt assembly to the second conveyor belt assembly;

[0010] The ultrasonic generator is provided with at least two pieces, the first conveyor belt assembly comprises a plurality of first conveyor belts arranged at intervals in front and back, and at least one ultrasonic generator is arranged in a plurality of central cavities of the plurality of first conveyor belts in front and back; the second conveyor belt assembly comprises a plurality of second conveyor belts arranged at intervals in front and back, and at least one ultrasonic generator is arranged in a plurality of central cavities of the plurality of second conveyor belts in front and back.

[0011] By adopting the above technical solution, the ultrasonic generator is closer to the plate, and the cleaning effect of the plate is better, and the flipping mechanism can flip the plate, so that the front and back sides of the plate can be cleaned in turn by the ultrasonic generator in the central cavity of the first conveyor belt and the ultrasonic generator in the central cavity of the second conveyor belt, so that both the front and back sides of the plate can be cleaned. When the plate is flipped from the first conveyor belt to the second conveyor belt, the bottom surface of the plate that was originally in contact with the first conveyor belt leaves the first conveyor belt and is completely in contact with the liquid in the cleaning chamber for ultrasonic cleaning. The front and back sides of the plate are switched and completely exposed, so that the area of ​​the plate blocked by the conveyor belt can also be cleaned more cleanly.

[0012] Furthermore, the flap structure includes a rotating shaft rotatably assembled on the frame and a flip member rotatably mounted on the rotating shaft, the top of the flip member is provided with a receiving groove opening upward, a first torsion spring is connected between the flip member and the frame, the first torsion spring is used to keep the flip member in a state where the receiving groove receives the plate on the first conveyor belt, a movable rod is elastically slidably penetrated through the flip member along the radial direction of the rotating shaft, the top of the movable rod is located in the receiving groove, and the movable rod is used to be squeezed by the plate inserted in the receiving groove to move downward and press against the rotating shaft.

[0013] With the above technical solution, when the plate is inserted from the first conveyor belt assembly into the receiving groove on the flipping member, the movable rod can be pressed downward, so that the movable rod moves downward and is pressed against the rotating shaft. At this time, the rotating shaft can drive the flipping member to rotate synchronously to flip the plate onto the second conveyor belt assembly. After the plate is transported upward with the second conveyor belt assembly and leaves the receiving groove, the flipping member is reset under the action of the first torsion spring. The flipping member is triggered by the plate to automatically start flipping, and automatically resets after the plate leaves. Compared with setting a sensor to detect the position of the plate and then controlling the rotation of the flipping member according to the detection result of the sensor, the structure is simpler and the flipping member is more sensitive.

[0014] Furthermore, the flip member includes a plurality of rotating blocks and a plurality of connecting plates. The plurality of rotating blocks are arranged at intervals in front and behind. The plurality of connecting plates are respectively connected between each two adjacent rotating blocks. The top of the rotating block is provided with a U-shaped groove with an opening facing upward and passing through front and back. The U-shaped grooves on the plurality of rotating blocks are opposite and connected front and back. The plurality of U-shaped grooves form the receiving groove. A movable rod is elastically slidably penetrated along the radial direction of the rotating shaft on each rotating block, and the top of each movable rod is located in the U-shaped groove on the corresponding rotating block.

[0015] Furthermore, the rotating block includes a rotating body rotatably mounted on a rotating shaft, and a push plate and a baffle connected to the top surface of the rotating body. The push plate and the baffle are arranged at intervals from left to right. The push plate, the baffle and the top surface of the rotating body form the U-shaped groove. The movable rod is elastically slidably penetrated into the rotating body along the radial direction of the rotating shaft.

[0016] Furthermore, the push plate is longer than the baffle.

[0017] The above technical solution is adopted to facilitate supporting the left side of the plate during the flipping process, thereby ensuring that the plate can be smoothly flipped onto the second conveyor belt assembly.

[0018] Furthermore, the first conveyor belt is provided with a plurality of first supporting structures arranged at intervals along the rotating path of the first conveyor belt, the first supporting structure comprising a first fixed shaft fixedly connected to the front / rear side walls of the first conveyor belt and extending forward and backward, a first rotating plate rotatably mounted on the first fixed shaft, and a second torsion spring connected between the first fixed shaft and the first rotating plate, the second torsion spring keeps the first rotating plate in an inclined state so that an end of the first rotating plate facing away from the first fixed shaft is located on the left side of the first fixed shaft and protrudes upward from the upper surface of the first conveyor belt.

[0019] By adopting the above technical solution, when the plate falls on the first conveyor belt, the first rotating plate flips to the right and unfolds under the pressure of the plate, thereby supporting the plate and making the plate move synchronously with the first conveyor belt, preventing the plate from sliding downward relative to the first conveyor belt and moving to the bottom of the V-shaped groove too quickly, thereby ensuring that the cleaning time of the bottom surface of the plate is long enough.

[0020] Furthermore, the second conveyor belt is provided with a plurality of groups of second supporting structures arranged at intervals along the rotating path of the second conveyor belt, the second supporting structures include a second fixed shaft fixedly connected to the front / rear side walls of the second conveyor belt and extending front and rear, a second rotating plate rotatably mounted on the second fixed shaft, and a third torsion spring connected between the second fixed shaft and the second rotating plate, the third torsion spring is used to keep the second rotating plate in a state parallel to the upper surface of the second conveyor belt, the second rotating plate is connected to a gear rod extending front and rear on the side facing away from the second conveyor belt, each of the second conveyor belts is provided with a rotating block on the front and rear sides, and a pushing block is provided on the opposite sides of the two rotating blocks respectively located on the front and rear sides of each second conveyor belt, and a pushing inclined surface is provided on the side of the pushing block facing away from the second conveyor belt.

[0021] By adopting the above technical solution, the second rotating plate supports the plate and transports it upward, ensuring that the plate can be moved upward by the second conveyor belt.

[0022] Furthermore, a wind knife assembly is provided at the output end of the second conveyor belt assembly, and the wind knife assembly includes a first blowing pipe and a second blowing pipe, the first blowing pipe extends forward and backward and is arranged above the second conveyor belt, and the second blowing pipe extends forward and backward and is passed through the central cavity of multiple second conveyor belts.

[0023] By adopting the above technical solution, after the plate leaves the cleaning chamber, it passes through the wind knife assembly, and the wind knife assembly can blow air toward the front and back sides of the plate, thereby making the plate dry.

[0024] The beneficial effect of the automatic cleaning device for plate production provided by the present invention is that the front and back sides of the plate can be cleaned more thoroughly, and the cleaning effect is better.

[0025] The present invention provides an automatic cleaning method for plate production, comprising the following steps:

[0026] S1. Place the plate to be cleaned on the conveying roller group on the left and convey it to the right. When the plate moves to the top of the first conveyor belt assembly, it tilts downward and falls on the first conveyor belt in the cleaning chamber. The plate is conveyed downward along with the first conveyor belt, and at the same time, the ultrasonic generator in the central cavity of the first conveyor belt cleans the bottom surface of the plate.

[0027] S2, the plate moves downward with the first conveyor belt to the bottom of the V-shaped groove and is inserted into the receiving groove in the flap structure, and the flap structure rotates to flip the plate onto the second conveyor belt;

[0044] like Figure 1 , Figure 3As shown, the frame 1 is arranged on a horizontal ground, and the frame 1 includes a bracket 101, a V-shaped plate 104 and a box 102. There are two brackets 101, and the two brackets 101 are arranged at intervals on the left and right. There are two V-shaped plates 104, and the two V-shaped plates 104 are arranged at intervals on the front and back and connected between the two brackets 101.

[0045] like Figure 1 As shown, there are two conveying roller groups 3, which are respectively installed on the top of two brackets 101, and the outer sides of the two conveying roller groups 3 are both covered with conveying belts 4, and the two conveying roller groups 3 convey from left to right.

[0046] like Figure 3 As shown, the first conveyor belt assembly is connected between the left halves of the two V-shaped plates 104, the first conveyor belt assembly tilts downward from left to right, and conveys from the upper left to the lower right, and the input end of the first conveyor belt assembly is connected below the output end of the conveying roller group 3 located on the left.

[0047] like Figure 3 As shown, the first conveyor belt assembly includes a first conveyor wheel set and a first conveyor belt 7 .

[0048] There are multiple first conveying wheel groups, and all are connected between the left halves of the two V-shaped plates 104. The multiple first conveying wheel groups are arranged at equal intervals up and down. The first conveying wheel group located at the top is the first driven conveying wheel group, the first conveying wheel group located at the bottom is the first active conveying wheel group, and the rest are first auxiliary supporting wheel groups.

[0049] The first conveying wheel group includes a first wheel shaft 20 and four first conveying wheels 21. The first wheel shaft 20 extends in the front-to-back direction. The first conveying wheels 21 are sleeved on the first wheel shaft 20 and fixedly connected to the first wheel shaft 20. The four first conveying wheels 21 are arranged at equal intervals in front and back. The multiple first conveying wheels 21 corresponding to each other in the upper and lower parts of each first conveying wheel group are called a first conveying wheel column.

[0050] There are four first conveyor belts 7, and the four first conveyor belts 7 are respectively sleeved on the outside of the four rows of first conveying wheels in the first conveyor belt assembly.

[0051] like Figure 3 , Figure 5 As shown, the second conveyor belt assembly is connected between the right halves of the two V-shaped plates 104, the second conveyor belt assembly tilts downward from right to left, and transports from the lower left to the upper right, and the output end of the second conveyor belt assembly is connected below the input end of the conveying roller group 3 located on the right side.

[0052] The second conveyor belt assembly includes a second conveyor wheel set and a second conveyor belt 6 .

[0053] There are multiple sets of second conveying wheel groups, and all are connected between the right halves of the two V-shaped plates 104. The multiple sets of second conveying wheel groups are arranged at equal intervals up and down. The second conveying wheel group located at the top is the second driven conveying wheel group, the second conveying wheel group located at the bottom is the second active conveying wheel group, and the rest are second auxiliary supporting wheel groups.

[0054] The second conveying wheel group includes a second wheel shaft 22 and five second conveying wheels 23. The second wheel shaft 22 extends in the front-to-back direction. The second conveying wheels 23 are sleeved on the second wheel shaft 22 and fixedly connected to the second wheel shaft 22. The five second conveying wheels 23 are evenly spaced front to back. The plurality of second conveying wheels 23 corresponding to each other in the upper and lower parts of each second conveying wheel group is called a second conveying wheel column.

[0055] There are five second conveyor belts 6, and the five second conveyor belts 6 are respectively sleeved on the outside of the five rows of second conveying wheels in the second conveyor belt assembly.

[0056] The second conveying wheel arrays and the first conveying wheel arrays are arranged in a staggered manner front to back, so the second conveying belts 6 and the first conveying belts 7 are also arranged in a staggered manner front to back.

[0057] like Figure 3 As shown, the first active conveying wheel group and the second active conveying wheel group share a wheel axle, that is, each first conveying wheel 21 in the first active conveying wheel group and each second conveying wheel 23 in the second active conveying wheel group are installed on the same wheel axle, so that only driving the wheel axle to rotate can drive the first conveyor belt assembly and the second conveyor belt assembly to operate.

[0058] like Figure 3 , Figure 4 As shown, there are multiple first supporting assemblies, and each first conveyor belt 7 is provided with multiple groups of first supporting assemblies arranged at equal intervals along the rotation direction of the first conveyor belt 7.

[0059] The first supporting assembly includes two groups of first supporting structures connected to the front and rear sides of the first conveyor belt 7 symmetrically. The first supporting structure includes a first fixed shaft 14 , a first rotating plate 15 and a second torsion spring 16 .

[0060] The first fixed shaft 14 extends forward and backward and is fixedly connected to the front side wall or the rear side wall of the first conveyor belt 7. The first rotating plate 15 is rotatably mounted on the first fixed shaft 14. The second torsion spring 16 is connected between the first fixed shaft 14 and the first rotating plate 15. The second torsion spring 16 keeps the first rotating plate 15 in an inclined state so that the end of the first rotating plate 15 facing away from the first rotating shaft 8 is located on the left side of the first rotating shaft 8 and protrudes upward from the upper surface of the first conveyor belt 7. In this way, when a sheet material 2 falls on the first conveyor belt assembly, the first rotating plate 15 pressed by the sheet material 2 rotates downward, so that the bottom surface of the sheet material 2 is lower than the top of the first rotating plate 15 that is not pressed by the sheet material 2. When the sheet material 2 slides to the first rotating plate 15 on its right side that is not pressed, the first rotating plate 15 is pushed to the right by the sheet material 2 to better support the sheet material 2. The structure in the supporting state is as shown in FIG. Figure 4 shown.

[0061] like Figure 5 , Figure 6 As shown, there are multiple groups of second supporting components, and each second conveyor belt 6 is provided with multiple groups of second supporting components arranged at equal intervals along the rotation direction of the second conveyor belt 6.

[0062] The second supporting assembly includes two sets of second supporting structures which are symmetrically connected to the front and rear sides of the second conveyor belt 6. The second supporting structure includes a second fixed shaft, a second rotating plate 17, a shift rod 18 and a third torsion spring.

[0063] The second fixed shaft extends forward and backward and is fixedly connected to the front side wall or the rear side wall of the second conveyor belt 6. The second rotating plate 17 is rotatably mounted on the second fixed shaft. The side of the second rotating plate 17 facing away from the corresponding second conveyor belt 6 is connected with a shift rod 18 extending forward and backward. The third torsion spring is connected between the second fixed shaft and the second rotating plate 17. The third torsion spring is used to keep the second rotating plate 17 in a state parallel to the upper surface of the second conveyor belt 6.

[0064] like Figure 5 As shown, there are six ultrasonic generators 11, three ultrasonic generators 11 are inserted in the central cavity of the four first conveyor belts 7 in the first conveyor belt assembly, and the three ultrasonic generators 11 are arranged at equal intervals along the extension direction of the first conveyor belt assembly. Three ultrasonic generators 11 are inserted in the central cavity of the five second conveyor belts 6 in the second conveyor belt assembly, and the three ultrasonic generators 11 are arranged at equal intervals along the extension direction of the second conveyor belt assembly. The ultrasonic generator 11 is a prior art and will not be described in detail here.

[0065] like Figure 5 As shown, the turning mechanism is located at the bottom of the V-shaped groove surrounded by the first conveyor belt assembly and the second conveyor belt assembly, and the turning mechanism includes a flap structure and a motor.

[0066] like Figure 7As shown, the flap structure includes a rotating shaft 8, a turning member and a movable rod 13.

[0067] The rotating shaft 8 extends forward and backward, and the front and rear ends of the rotating shaft 8 are rotatably mounted on the bottom ends of the two V-shaped plates 104 respectively.

[0068] like Figure 7 , Figure 8 As shown, the flipping member includes a rotating block 9 , a connecting plate 10 and a sleeve 24 .

[0069] like Figure 5 As shown, there are multiple rotating blocks 9, which are arranged at intervals in the front and rear and are all rotatably mounted on the rotating shaft 8. The multiple rotating blocks 9 can be divided into multiple rotating block groups, and each rotating block group includes two rotating blocks 9 respectively arranged on the front and rear sides of the second conveyor belt 6.

[0070] like Figure 7 , Figure 8 As shown, the rotating block 9 includes a rotating body 901, a push plate 902 and a baffle 903, the push plate 902 and the baffle 903 are arranged at intervals from left to right and are both connected to the top surface of the rotating body 901, the push plate 902 is longer than the baffle 903, and a U-shaped groove 904 with an opening facing upward and penetrating from front to back is formed between the push plate 902, the baffle 903 and the top surface of the rotating body 901. The two rotating bodies 901 in each rotating block group are connected to one side facing each other with a push block 905, and the push block 905 is provided with a push inclined surface 906 inclined from top to bottom toward the second conveyor belt 6.

[0071] When the flipping piece flips to the side where the second conveyor belt assembly is located, the pushing slope 906 flips to a state of tilting upward from left to right. When the gear lever 18 in the second supporting structure moves upward with the second conveyor belt 6 until it contacts the pushing slope 906, the gear lever 18 is pushed by the pushing slope 906 and rotates to the left, thereby unfolding the second rotating plate 17 to support the plate 2.

[0072] There are multiple connecting plates 10, and each adjacent two rotating blocks 9 are connected with a connecting plate 10. Any two adjacent connecting plates 10 are arranged on the left and right sides of the rotating block 9. The multiple connecting plates 10 connect the multiple rotating blocks 9 into a whole, and keep the U-shaped grooves 904 on each rotating block 9 corresponding to each other and connected, so that each U-shaped groove 904 together forms a receiving groove on the flip part.

[0073] There are two sleeves 24, which are respectively connected to the front side of the rotating block 9 located at the frontmost side and the rear side of the rotating block 9 located at the rearmost side. Both sleeves 24 are rotatably mounted on the rotating shaft 8, and a first torsion spring 12 is connected between the sleeve 24 and the rotating shaft 8.

[0074] like Figure 7 , Figure 8 As shown, there are multiple movable rods 13, and the number of movable rods 13 is equal to the number of rotating blocks 9. The movable rod 13 is perpendicular to the top surface of the rotating body 901 and is slidably inserted into the rotating body 901. An elastic member is connected between the movable rod 13 and the rotating body 901, so as to realize the elastic sliding connection of the movable rod 13 on the rotating body 901. The elastic member is a compression spring that can be extended and retracted along the rod length direction of the movable rod 13. The elastic member allows the movable rod 13 to maintain a state in which the top end protrudes from the top surface of the rotating body 901 and extends into the U-shaped groove 904 in a natural state. When the movable rod 13 is squeezed by the plate 2 inserted into the U-shaped groove 904, the bottom end can be pressed against the rotating shaft 8, so that the rotating shaft 8 drives the movable rod 13 to rotate through friction transmission, and then drives the flipping member to rotate synchronously with the rotating shaft 8, and flips the plate 2 on the first conveyor belt assembly to the second conveyor belt assembly. After the plate 2 leaves the U-shaped groove 904 along with the second conveyor belt assembly, the movable rod 13 is reset and separated from the rotating shaft 8, and the second torsion spring 16 drives the flipping member to reset.

[0075] The motor is mounted on one of the V-shaped plates 104 , and is in transmission connection with the rotating shaft 8 , so as to drive the rotating shaft 8 to rotate.

[0076] like Figure 1 , Figure 5 As shown, the air knife assembly is installed at the conveying end of the second conveyor belt assembly, and the air knife assembly is located above the liquid level of the cleaning liquid in the box 102. The air knife assembly includes two blowing pipes arranged at intervals up and down, and the blowing pipes extend in the front-to-back direction. One of the blowing pipes is located above the second conveyor belt 6 and is provided with a spacing greater than the thickness of the plate 2 between the blowing pipe and the upper surface of the second conveyor belt 6. The blowing pipe is the first blowing pipe 19, and the other blowing pipe is inserted into the hollow inner cavity of the second conveyor belt 6. The blowing pipe is the second blowing pipe 25. The two blowing pipes are provided with air outlets extending forward and backward on one side facing each other, and the air blown out of the air outlets in the two blowing pipes is blown to the front and back sides of the plate 2 respectively to dry the front and back sides of the plate 2.

[0077] like Figure 1As shown, the arc-shaped housing 5 is connected between two V-shaped plates 104 and is located above the input end of the first conveyor belt assembly. The arc-shaped housing 5 includes an arc-shaped top plate and two vertical connecting plates 10 respectively connected to the front and rear sides of the arc-shaped top plate. The two vertical connecting plates 10 are respectively connected to the two V-shaped plates 104. The left end of the arc-shaped top plate is higher than the top surface of the conveyor belt 4 on the conveyor roller group 3 on the left side, forming a plate inlet. The right end of the arc-shaped top plate is higher than the upper surface of the first conveyor belt 7, forming a plate outlet. The width dimension of the plate inlet is greater than the width dimension of the plate outlet. A gap is provided between the inner side wall of the arc-shaped top plate and the conveyor roller group 3 on the left side in the left-right direction, and the gap dimension is longer than the width dimension of the plate 2 in the left-right direction. The arc-shaped housing 5 is used to block the plate 2 above the plate 2 when the plate 2 falls on the first conveyor belt assembly to prevent the plate 2 from rolling on the first conveyor belt assembly.

[0078] The automatic cleaning device for the production of a plate 2 provided by the present invention can effectively remove impurities and dirt on both sides of the plate 2, and has a better cleaning effect.

[0083] S2, the plate 2 moves downward with the first conveyor belt 7 to the bottom of the V-shaped groove and is inserted into the receiving groove in the flip member, the plate 2 pushes the movable rod 13 so that the bottom end of the movable rod 13 is pressed against the rotating shaft 8, the movable rod 13 rotates rightward with the rotating shaft 8 to drive the flip member to rotate rightward, and the plate 2 is flipped onto the second conveyor belt 6 with the flip member;

[0084] S3. The second supporting assembly supports the plate 2, and the second conveyor belt 6 drives the plate 2 to be conveyed upward. At the same time, the ultrasonic generator 11 in the central cavity of the second conveyor belt 6 cleans the top surface of the plate 2. The plate 2 moves to the wind knife assembly for drying, and then moves to the output end of the second conveyor belt 6. Under its own weight, it tilts downward and falls horizontally on the conveying roller group 3 on the right to continue to be conveyed to the right.
