Technical Field

[0001] The present application relates to the field of glaze spraying equipment, and in particular to a glaze spraying equipment. Background Art

[0002] Ceramic tiles are made of clay minerals such as clay and quartz sand as the main raw materials, through multiple processes such as molding, drying, forging, and glazing. They are widely used for covering building roofs. The glazing is sprayed with glaze equipment to improve the sealing of ceramic tiles and reduce the leakage rate.

[0003] Currently, a Chinese utility model patent with publication number CN21618149U discloses a glaze spraying device, comprising a frame, a glaze spraying chamber connected to the frame, the glaze spraying chamber forming an inner cavity, and a material passage chamber on both sides of the glaze spraying chamber. A conveyor belt is provided on the frame and passes through the glaze spraying chamber. The conveyor belt passes through the material passage chamber, the glaze spraying chamber, and another material passage chamber in sequence. A glaze spraying head is provided in the glaze spraying chamber, the glaze spraying head is connected to a glaze supply mechanism, and the glaze spraying head is directed toward the tiles on the conveyor belt. This application has a feature that the glaze spraying chamber can control the range of the glaze sprayed out of the tile glazing, which can prevent the glaze from escaping to the outside as much as possible, and can minimize pollution to the environment outside the tile glazing.

[0004] Regarding the above-mentioned related technologies, the inventors believe that there are the following defects: after the transmission belt passes through the glaze spraying chamber, part of the glaze slurry will stick to the transmission belt, and the glaze slurry on the transmission belt has not yet dried and comes into contact with subsequent tiles, causing the surfaces that do not need to be glazed to come into contact with the glaze slurry, resulting in poor quality of the tiles. Utility Model Content

[0005] In order to reduce the direct contact between the undried glaze slurry on the conveyor belt and the tiles, the present application provides a glaze spraying device.

[0006] The present application provides a glaze spraying device, which adopts the following technical solution:

[0007] A glaze spraying device includes a glaze spraying box, a conveying component for conveying tiles, and a scraping component. The conveying component includes a conveying frame, a conveyor belt, two conveying rollers, and a conveying motor. The conveying frame is arranged on the glaze spraying box, and the two conveying rollers are distributed on both sides of the glaze spraying box. The conveying rollers are rotatably connected to the conveying frame, the conveyor belt is sleeved on the conveying rollers, and the conveying motor is used to drive one of the conveying rollers to rotate. The scraping component includes a scraper, which is arranged on the conveying frame and abuts against the outer wall of the conveyor belt. A glaze spraying box is provided with a glaze spraying component for spraying glaze slurry.

[0008] By adopting the above technical solution, the staff places the tiles on the conveyor belt, the conveyor motor drives the conveyor roller to rotate, the conveyor roller drives the conveyor belt to move, and the conveyor belt sends the tiles into the glaze spraying box. The glaze spraying assembly in the glaze spraying box sprays glaze slurry on the tiles to improve the sealing and waterproof properties of the tiles. During the glazing process, the glaze slurry is easy to stick to the conveyor belt, and the scraper abuts against the outer wall of the conveyor belt. The undried glaze slurry on the conveyor belt will be scraped off by the scraper, reducing the contact between the glaze slurry on the conveyor belt and the unglazed surface of the tiles during subsequent transmission, thereby improving the quality of the tiles.

[0009] Optionally, the scraping assembly further includes a recovery box, which is located below the scraper and is arranged on the conveying rack.

[0010] By adopting the above technical solution, the undried glaze slurry can be recycled and reused, and the glaze slurry scraped off by the scraper falls into the recycling box under the action of gravity for collection, which is in line with the concept of green environmental protection.

[0011] Optionally, there are two groups of conveying components, and the two groups of conveying components are distributed along a direction perpendicular to the movement direction of the tiles. The conveying frame is slidably connected to the glaze spraying box along the distribution direction of the two groups of conveying components.

[0012] By adopting the above technical solution and setting up two conveying components, a narrower conveyor belt can be used to support the tiles, which can greatly reduce the contact area between the tiles and the conveyor belt. Since the sizes of tiles are different, the distance between the two conveyor racks can be changed to support tiles of different sizes, thereby improving the applicability of the glaze spraying equipment.

[0013] Optionally, the glaze spray box is also provided with an adjustment component for adjusting the distance between the two conveying components, the adjustment component includes an adjustment motor and a bidirectional screw, the length direction of the bidirectional screw is parallel to the sliding direction of the conveying rack, the two conveying racks are respectively threadedly connected to the threaded sections of the bidirectional screw with opposite rotation directions, the bidirectional screw is rotatably connected to the glaze spray box, and the adjustment motor is used to drive the bidirectional screw to rotate.

[0014] By adopting the above technical solution, when it is necessary to adjust the distance between the two conveyor belts to adapt to the size of the tiles, the staff can drive the adjustment motor, and the adjustment motor drives the bidirectional screw to rotate, and the bidirectional screw drives the two conveyor racks closer or farther away from each other until the two conveyor belts can support the tiles. The adjustment component has a simple structure and is easy for the staff to operate.

[0015] Optionally, a receiving groove for receiving excess glaze slurry is provided in the glaze spray box, and a drainage groove is provided on the side wall of the receiving groove, and the drainage groove is used to lead the excess glaze slurry out of the glaze spray box. A receiving component is provided on the outer wall of the glaze spray box, and the receiving component is used to receive the excess glaze slurry led out from the drainage groove.

[0016] By adopting the above technical solution, due to the different sizes of tiles, the glaze slurry sprayed by the glaze spraying assembly may not be able to contact all the tiles. Part of the glaze slurry will be sprayed onto the tiles, part of the glaze slurry will be sprayed onto the conveyor belt, and the remaining glaze slurry will be sprayed into the receiving trough. When the glaze slurry in the receiving trough gradually increases, the glaze slurry will flow out of the glaze spraying box through the drainage trough and into the receiving assembly, so that the subsequent glaze slurry can be recycled and reused.

[0017] Optionally, the receiving assembly includes a receiving box and a sliding seat, the sliding seat is provided on the side wall of the glaze spraying box, and the receiving box is slidably connected to the sliding seat in a direction approaching or away from the drainage groove.

[0018] By adopting the above technical solution, the receiving box is slidably connected to the sliding seat. The receiving box is used to receive the glaze slurry flowing out of the drainage trough. The glaze slurry in the receiving box can be recycled, which is in line with the concept of green environmental protection.

[0019] Optionally, the receiving assembly further includes a first magnet and a second magnet, the first magnet is arranged on the side wall of the glaze spray box, the second magnet is arranged on the receiving box, and the first magnet is used to attract the second magnet.

[0020] By adopting the above technical solution, when the receiving box slides in the sliding seat, the second magnet on the receiving box will attract the first magnet on the glaze spraying box. The attraction between the first magnet and the second magnet will drive the receiving box to remain in contact with the side wall of the glaze spraying box, so that the excess glaze slurry flowing out of the drainage trough can enter the receiving box.

[0021] Optionally, the receiving groove is arranged at an angle, and the drainage groove is opened at the lowest point of the receiving groove.

[0022] By adopting the above technical solution, the receiving trough is tilted, and the excess glaze slurry received in the receiving trough will move toward the drainage trough under the action of gravity, making it easier for the receiving box to collect the glaze.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The scraping component is used to reduce the contact between the undried glaze slurry on the conveyor belt and the subsequent tiles, thereby improving the quality of the tiles;

[0025] 2. The adjustment component is used to adjust the distance between the two conveying components, so that the conveyor belt can convey tiles of different sizes, thereby increasing the applicability of the equipment;
