Description

Technical Field

[0001] This utility model relates to the field of soft porcelain production technology, and in particular to a soft porcelain conveying device with a cleaning function. Background Technology

[0002] Flexible ceramic tiles, also known as PVC tiles, are typically produced using robotic arms to automatically control nozzles and spray slurry onto the conveyor belt to create printed patterns. This process is often used for touch-up spraying. Existing technology, patent number CN105080765A, discloses a flexible ceramic tile forming spraying machine. This machine features high-pressure water nozzles on its inner wall to clean the casing and cool it down in case of excessive heat, ensuring optimal spraying performance. However, during the slurry spraying process, some slurry inevitably adheres to the conveyor belt.

[0024] like Figures 1 to 4As shown, this utility model provides a flexible ceramic conveying device with a cleaning function, including a spraying conveying mechanism 10. The spraying conveying mechanism 10 includes a frame 11, on which two sets of rotating shafts 12 are rotatably mounted. A conveyor belt 13 is driven and wound between the two sets of rotating shafts 12. A cleaning tank 20 is provided on the frame 11 below the two sets of rotating shafts 12. A cleaning pressure roller assembly 30 is rotatably mounted on the frame 11 inside the cleaning tank 20. The cleaning pressure roller assembly 30 is located inside the conveyor belt 13 and can press the lower section of the conveyor belt 13 against the inside of the cleaning tank 20. The spraying conveying mechanism 10 is part of a flexible ceramic production line, and the cleaning tank 20 and the cleaning pressure roller assembly 30 can be directly installed on an existing production line. When the conveyor belt 13 passes through the cleaning tank 20, most of the slurry adhering to its surface can be directly cleaned by water.

[0025] See Figure 2 and Figure 3 In a specific embodiment of this application, since the conveyor belt 13 currently used is a high-temperature resistant rubber tube conveyor belt, the slurry may flow and adhere to its lower surface during the spraying process, requiring simultaneous cleaning of the lower surface. Therefore, the cleaning tank 20 is equipped with a scraping assembly 40 that can move against the lower surface of the conveyor belt 13 located in the lower section. Specifically, the scraping assembly 40 includes a scraping head 41, and the cleaning tank 20 is equipped with a mounting block 42. The scraping head 41 is hinged to the mounting block 42 via a rotating shaft 43 and can move against the lower surface of the conveyor belt 13. The cleaning tank 20 is equipped with a rotary motor 44 whose drive end is connected to one end of the rotating shaft 43. The conveyor belt 13 can pass between the cleaning roller assembly 30 and the scraper head 41, while cleaning the upper and lower surfaces of the conveyor belt 13; the rotary motor 44 can rotate to control the angle of the scraper head 41, ensuring that the scraper head 41 can fit against the lower surface of the conveyor belt 13; the scraper head 41 can be a scraper or a brush head.

[0026] See Figure 4In a specific embodiment of this application, the cleaning roller assembly 30 includes a roller 31 and two sets of lifting rods 32. Lifting grooves 21 are provided on both sides of the cleaning tank 20. The two sets of lifting rods 32 are movably inserted into the two sets of lifting grooves 21, and the roller 31 is rotatably mounted between the two sets of lifting rods 32 via a roller shaft 33. Specifically, several positioning holes 22 corresponding to the lifting grooves 21 are spaced apart along the height direction on both sides of the cleaning tank 20. Each set of lifting rods 32 has a locking hole 34 that can cooperate with the positioning hole 22. A fastening bolt 23 that can extend into the corresponding locking hole 34 is movably inserted into the positioning hole 22. The height of the roller shaft 33 can be adjusted by the lifting rods 32 to change the depth at which the conveyor belt 13 is pressed into the cleaning tank 20, ensuring that the conveyor belt 13 can completely enter the cleaning tank 20. Furthermore, the outer surface of the pressure roller 31 is provided with a plurality of cleaning bristles 35, and the pressure roller 31 can simultaneously clean the upper surface of the conveyor belt 13.

[0027] Furthermore, the frame 11 is provided with a pressing roller 13 on one side of the cleaning tank 20. The pressing roller 13 can move and press against the outer surface of the conveyor belt 13 located in the lower section. The pressing roller 13 can play the role of tensioning the conveyor belt 13.

[0028] In addition, the cleaning tank 20 is connected to a water inlet pipe 24 and a drain pipe 25. Both the water inlet pipe 24 and the drain pipe 25 are equipped with electric valves to facilitate timely replacement of the cleaning water in the cleaning tank 20. A control system is also included. The cleaning tank 20 is equipped with a low-level sensor 26 and a high-level sensor 27. The control system can control the opening or closing of the electric valves of the water inlet pipe 24 and the drain pipe 25 respectively based on the level signals sent by the low-level sensor 26 and the high-level sensor 27. Specifically, the control system includes a central processing unit and a controller that are electrically connected to each other. The low liquid level sensor 26 and the high liquid level sensor 27 are both electrically connected to the central processing unit. The electrically controlled valves of the inlet pipe 24 and the drain pipe 25 are respectively electrically connected to the controller. The central processing unit can receive and process the liquid level signals sent by the low liquid level sensor 26 and the high liquid level sensor 27. The controller can control the opening or closing of the electrically controlled valves of the inlet pipe 24 and the drain pipe 25 according to the processing results of the central processing unit. The central processing unit and the controller are both prior art and will not be described in detail in this application.
