Description

Technical Field

[0001] The present invention belongs to the technical field of ceramic plates, and particularly relates to a novel coating device for flat ceramic plates. Background Art

[0002] Ceramic plates are produced using zirconia or alumina. Ceramic plates have extremely strong weather resistance, and neither sunlight, rain, nor moisture has any impact on the surface and substrate. The resistance to ultraviolet irradiation and color stability fully reach international gray levels 4 - 5.

[0003] Flat ceramic membranes are widely used in water treatment fields such as municipal sewage treatment, tap water treatment, and industrial wastewater treatment. In many water treatment processes, while having good filtration accuracy, a high filtration flux is also desired. To achieve this goal, the traditional method uses the approach of secondary film spraying and secondary firing. The particle size of the film spraying material in the second time is smaller than that in the first time, which can prevent the small - particle film spraying material from penetrating into the matrix of the flat ceramic plate, but this greatly increases the production cost of the flat ceramic plate.

Specific embodiments

[0025] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0026] Please refer to Figures 1-3 , the present invention provides a technical solution: a new coating device for flat ceramic plates, including a conveying component 1, a coating component 2, a laminating component 3 and an aggregate component 4.

[0027] The conveying component 1 includes a conveying frame 11, on which a conveyor belt 12 is installed, and a plurality of support legs 13 are installed at the bottom of the conveying frame 11.

[0028] The conveying component 1 is used to convey the ceramic plate 15 to be coated, and the ceramic plates 15 are arranged at intervals on the conveyor belt 12. Four support legs 13 are provided and evenly divided into two groups, which are respectively arranged at the lower edges of both sides of the conveying frame 11, and the support legs 13 can provide stable support for the conveying frame 11.

[0029] In order to improve the support stability of the support legs 13, a foot pad 14 is sleeved on the lower end of the support legs 13. The foot pad 14 is made of rubber material. The top of the foot pad 14 has a groove for receiving the support leg 13, and the lower end of the support leg 13 is detachably embedded in the groove, which is convenient for disassembly.

[0030] The coating assembly 2 is used to spray coating material onto the decal paper 241. The coating assembly 2 includes a first support frame 21, a second support frame 22 and a top beam 23. There are two first support frames 21 which are located on both sides of the conveying frame 11. A first receiving roller 211 and a second receiving roller 212 which are symmetrically arranged up and down are connected between the two first support frames 21. There are two second support frames 22 which are located on one side of the end of the conveying frame 11. A feeding roller 24 is connected between the two second support frames 22. The decal paper 241 is wound around the feeding roller 24. The top beam 23 is fixedly connected to the upper ends of the first support frame 21 and the second support frame 22. A spraying device 26 and material conveying frames 25 located on both sides of the spraying device 26 are fixed to the bottom of the top beam 23. The spraying device 26 is used to spray coating material onto the decal paper 241. A material conveying roller 251 is installed at the lower end of the material conveying frame 25.

[0031] Among them, the first support frame 21 has an inverted T-shaped structure, and the two first support frames 21 are arranged oppositely. The first support frame 21 and the second support frame 22 can provide support for the top frame 23. The first receiving roller 211 and the second receiving roller 212 are used to convey the decal paper 241. The second receiving roller 212 is located below the first receiving roller 211 and the axes of both are on the same vertical line. Both the first receiving roller 211 and the second receiving roller 212 are rotatably connected to the first support frame 21 through bearings. The feeding roller 24 is used to provide the decal paper 241 to be sprayed. When the decal paper 241 is released, the feeding roller 24 rotates clockwise. The decal paper 241 is conveyed to the lower part of the spraying device 26 through a material conveying roller 251. The spraying device 26 directly sprays the coating material with high precision on one side of the specific decal paper 241, and then is conveyed to the first receiving roller 211 through another material conveying roller 251, and then conveyed to the second receiving roller 212. The side of the decal paper 241 without coating material contacts the first receiving roller 211 and the second receiving roller 212. When the decal paper 241 passes through the second material conveying roller 251, the coating material on its surface can be pressed evenly by the material conveying roller 251.

[0032] A flattening frame 27 is arranged on the side of the feeding roller 24 close to the material conveying frame 25. The upper end of the flattening frame 27 is fixedly connected to the top beam 23; two oppositely arranged flattening rollers 271 are installed at the lower end of the flattening frame 27. The upper end of the flattening frame 27 is detachably installed on the top beam 23 through fixing bolts. There is a gap for the decal paper 241 to pass between the two flattening rollers 271. And before the decal paper 241 passes through the first material conveying roller 251, it is first pressed flat by the flattening rollers 271 to facilitate subsequent spraying operations.

[0033] Both ends of the material feeding roller 24 are connected to the second vertical frame 22 through roller shafts, and the second vertical frame 22 is provided with shaft holes for accommodating the roller shafts; an installation groove communicating with the shaft holes is formed on the second vertical frame 22, and a cover plate 242 is installed in the installation groove. The cover plate 242 has a protrusion matching the installation groove, and the protrusion has a semi-circular shaft hole one. There is a semi-circular shaft hole two corresponding to the semi-circular shaft hole in the installation groove. The semi-circular shaft hole one and the semi-circular shaft hole two can enclose a complete shaft hole. The cover plate 242 is installed on the second vertical frame 242 through fixing bolts. The cover plate 242 can provide support for the roller shaft, and is convenient to disassemble, facilitating the replacement of the material feeding roller 24.

[0034] The outer peripheral wall of the material conveying roller 251 is coated with an anti-sticking coating. In this embodiment, the anti-sticking coating can adopt the anti-sticking coating with the model number 568 provided by Dongguan Jinnai New Materials Co., Ltd. By setting the anti-sticking coating, the film material or the flower paper 241 can be reduced from adhering to the material conveying roller 251, reducing the waste of the film material and improving the product quality.

[0035] The laminating assembly 3 includes a cross frame 31. The cross frame 31 is located below the material conveying roller 251. Both ends of the cross frame 31 are respectively fixedly connected to the first vertical frame 21 and the second vertical frame 22. At least two laminating frames 33 are arranged at the bottom of the cross frame 31. A laminating roller 331 is installed at the bottom of the laminating frame 33. A cutting cylinder 32 is arranged between the two laminating frames 33. The cutting cylinder 32 is fixed to the bottom of the cross frame 31, and the output end of the cutting cylinder 32 faces downward and is fixedly connected with a cutter 321.

[0036] The cross frame 31 is horizontally arranged. Installation plates are integrally formed at both ends of the cross frame 31. The installation plates are connected to the first vertical frame 21 and the second vertical frame 22 through fixing bolts. In this embodiment, three laminating frames 33 are provided and are evenly spaced along the length direction of the cross frame 31. The cutting cylinder 32 is located between the two leftmost laminating frames 33. The laminating roller 331 is rotatably connected to the laminating frame 33. After the flower paper 241 passes through the second receiving roller 212, the side of the flower paper 241 with the film material contacts the upper surface of the ceramic plate 15, so that the flower paper 241 can be attached to the ceramic plate 15 located below the second receiving roller 212, and then sequentially passes through the laminating rollers 331 at the lower ends of the three laminating frames 33. The laminating rollers 331 can press the flower paper 241, making the attachment between the flower paper 241 and the ceramic plate 15 tighter. The ceramic plate 15 with the flower paper 241 attached is conveyed from right to left. After passing through the middle laminating frame 33, the cutting cylinder 32 extends and drives the cutter 321 to move downward to cut off the flower paper 241 between two adjacent ceramic plates 15, and then continue to convey the ceramic plate 15, so that the finally output ceramic plates 15 can be placed separately, facilitating subsequent processing.

[0037] An elastic pad 332 is wrapped around the outer peripheral wall of the laminating roller 331. The elastic pad 332 can be made of rubber material. The elastic pad 332 has elasticity, can provide effective pressure, and because of its elasticity, it will not damage the transfer paper 241 and the ceramic plate 15, ensuring the product quality.

[0038] The aggregate component 4 is used to collect the ceramic plates 15 after film coating. The aggregate component 4 includes a base 41, a receiving plate 42 and a baffle 43; the receiving plate 42 and the baffle 43 are respectively fixed to the opposite side edges of the base 41. The receiving plate 42 is inclined and the baffle 43 is vertical; the upper edge of the receiving plate 42 is located below one end of the conveyor belt 12.

[0039] The base 41 is fixedly connected to the second vertical frame 22 and the base 41 is horizontally arranged. The receiving plate 42 is used to receive the ceramic plate 15, and the ceramic plate 15 can slide down along the inclined receiving plate 42 and fall into the base 41. At the same time, it can be limited by the baffle 43 to prevent the ceramic plate 15 from sliding out. The ceramic plates 15 are temporarily stored in the base 41 centrally, which is convenient for the staff to carry.

[0040] A buffer pad 44 is attached to the side surface of the baffle 43 facing the receiving plate 42 and the upper surface of the base 41. In this embodiment, the buffer pad 44 can be made of rubber material. When the ceramic plate 15 slides onto the base 41 and is blocked by the baffle 43, the buffer pad 44 can provide buffering, thereby reducing the damage caused by the impact.

[0041] A novel coating device for a flat ceramic plate of the present invention, when in use, first places the ceramic plates 15 to be coated at uniform intervals on the conveyor belt 12, and passes the transfer paper 24 successively through the flattening roller 271, the feeding roller 251, the spraying device 26, the feeding roller 251, the receiving roller 1 211 and the receiving roller 2 212. Before the transfer paper 241 passes through the first feeding roller 251, it is first pressed and flattened by the flattening roller 271. The transfer paper 241 is conveyed to the lower part of the spraying device 26 through a feeding roller 251. The spraying device 26 directly sprays the film material with high precision on one side of the specific transfer paper 241, and then is conveyed to the receiving roller 1 211 through another feeding roller 251, and then to the receiving roller 2 212. The side of the transfer paper 241 without the film material contacts the receiving roller 1 211 and the receiving roller 2 212. When the transfer paper 241 passes through the second feeding roller 251, the film material on its surface can be pressed evenly by the feeding roller 251. After the transfer paper 241 passes through the receiving roller 2 212, the side of the transfer paper 241 with the film material contacts the upper surface of the ceramic plate 15, so that the transfer paper 241 adheres to the ceramic plate 15 located below the receiving roller 2 212, and then passes through three laminating rollers 331 in sequence. The laminating rollers 331 can press the transfer paper 241. The ceramic plate 15 with the transfer paper 241 attached is conveyed from right to left. After passing through the laminating frame 33 in the middle, the cutting cylinder 32 extends and drives the cutter 321 to move downward to cut off the transfer paper 241 between two adjacent ceramic plates 15, and then continues to convey the ceramic plate 15. The receiving plate 42 receives the ceramic plate 15 output from the left end of the conveyor belt 12, and the ceramic plate 15 can slide downward along the inclined receiving plate 42 and fall into the material seat 41. At the same time, it can be limited by the baffle 43 to prevent the ceramic plate 15 from sliding out. Finally, the ceramic plate 15 is fired in a calcining furnace. After firing, the transfer paper 241 is burned off, and the high-precision film layer on the surface directly adheres to the surface of the flat ceramic plate 15, forming a uniform surface filter membrane.

[0042] In summary, for a novel coating device for a flat ceramic plate of the present invention, by setting the conveyor belt 12 for conveying the ceramic plate 15, the spraying assembly 2 for spraying the film material on the transfer paper 241, and the laminating assembly 3 for attaching the transfer paper 241 sprayed with the film material to the ceramic plate 15, the film material can be coated on the ceramic plate 15 through the transfer paper 241. Then, through firing, the transfer paper 241 can be burned off, and the high-precision film layer on the surface directly adheres to the surface of the flat ceramic plate 15, forming a uniform surface filter membrane, and will not penetrate into the matrix to reduce the porosity.

[0043] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
