Description

Technical Field

[0001] This utility model relates to the field of coating roller cleaning, specifically to a coating roller scraper slurry suction device and coating roller cleaning equipment. Background Technology

[0002] After coating, the coating roller inevitably retains some slurry residue on its surface. Improper cleaning can easily lead to electrode contamination. In the prior art, a coating doctor blade is used to remove the slurry adhering to the coating roller. After the doctor blade scrapes off the slurry, further cleaning is required. Since the coating roller is located inside the equipment, the cleaning process is complex and space is limited, making it easy to cause mechanical damage due to improper operation, which in turn affects the coating thickness and reduces the production yield.

[0023] Please see Figure 1-2This utility model, in a preferred embodiment, provides a coating roller doctor blade slurry suction device, including a cleaning tank 1, a ball valve 2, a suction assembly 3, a moving assembly 4, and a silencer 5. A vacuum generator 15 is disposed above the cleaning tank 1, and the ball valve 2 is disposed on the vacuum generator 15. Compressed air is injected into the vacuum generator 15 through the ball valve 2, which generates a negative pressure inside the cleaning tank 1. This negative pressure is transmitted to the suction assembly 3, enabling the suction assembly 3 to generate suction force to suction the slurry. The moving assembly 4 is connected to the bottom of the cleaning tank 1 and is used to move the cleaning tank 1, allowing the entire device to be moved to any position on the coating roller for easy cleaning of various parts of the coating roller. The silencer 5 is disposed at the exhaust port of the vacuum generator 15, which reduces the noise generated by high-speed exhaust, improves the working environment, and meets industrial noise standards.

[0024] Specifically, the suction component 3 includes a connector 31 and an air gun suction component 32. The connector 31 connects the air gun suction component 32 and the cleaning tank 1. The air gun suction component 32 is used to suck up the slurry scraped off the surface of the coating roller. The connector 31 can transmit the negative pressure in the cleaning tank 1 to the air gun suction component 32, enabling it to generate suction. When the air gun suction component 32 is brought close to the coating roller, the residual slurry on the coating roller can be sucked into the cleaning tank 1 by the air gun suction component 32. This device solves the problem of inconvenient cleaning of the coating roller, reduces the risk of electrode contamination, reduces the time required for cleaning, and helps to improve the production yield. At the same time, the operator does not need to enter the coating equipment during the cleaning process, which plays a role in protecting the operator.

[0025] In this embodiment, the cleaning tank 1 is connected to a first connecting pipe 11, and the vacuum generator 15 is provided with a second connecting pipe 12 and a third connecting pipe 13. The first connecting pipe 11 is connected to the connector 31, the second connecting pipe 12 is connected to the ball valve 2, and the third connecting pipe 13 is connected to the silencer 5. The arrangement of each connecting pipe facilitates the connection of each component with the cleaning tank 1 and the vacuum generator 15, and facilitates installation.

[0026] The connector 31 includes a quick-connect fitting 311 and a connecting hose 312. The quick-connect fitting 311 is connected between the first connecting pipe 11 and the connecting hose 312, and the connecting hose 312 is connected between the quick-connect fitting 311 and the air gun suction device 32. The quick-connect fitting 311 facilitates the connection or separation of the first connecting pipe 11 and the connecting hose 312, and ensures safety and sealing. The connecting hose 312 is made of soft material and can be twisted at will, which facilitates changing the position of the air gun suction device 32 and further facilitates the suction of residual slurry from various positions of the coating roller.

[0027] In this embodiment, the air gun suction component 32 includes a gun body 321 and a suction nozzle 322. The gun body 321 is connected between the connecting hose 312 and the suction nozzle 322. A trigger 323 is provided on the gun body 321. The trigger 323 is used to disconnect or connect the connecting hose 312 and the suction nozzle 322. By pressing the trigger 323, the amount of negative pressure transmitted from the connecting hose 312 to the gun body 321 can be changed, thereby changing the suction force of the suction nozzle 322, making it convenient to use. Furthermore, the suction end of the suction nozzle 322 is connected to a flexible air tube 324. The flexible air tube 324 is soft and can avoid metal-to-metal contact with the surface of the coating roller, which helps protect the coating roller.

[0028] Please see Figure 2 There are three moving components 4 arranged in a triangle at the bottom of the cleaning bucket 1. This arrangement can provide stable support to the cleaning bucket 1 to ensure the stability of the cleaning bucket 1 during movement.

[0029] Specifically, the moving component 4 includes a roller 41, a rotating shaft 42, a bracket 43, and a bearing 44. The roller 41 is rotatably connected to the rotating shaft 42, the rotating shaft 42 is mounted on the bracket 43, and the bracket 43 is connected to the bottom of the cleaning bucket 1 through the bearing 44. During movement, the roller 41 rotates around the rotating shaft 42 to drive the cleaning bucket 1 to move in a straight line. The bracket 43 can rotate 360° relative to the cleaning bucket 1 in the horizontal plane to change the direction of movement of the cleaning bucket 1, further facilitating the movement of the cleaning bucket 1 to any position.

[0030] The cleaning bucket 1 is equipped with three handles 14. Two of the handles 14 are positioned opposite each other on the side wall of the cleaning bucket 1, and the other handle 14 is positioned on the vacuum generator 15. When moving, one hand can hold the top handle 14 and the other hand can hold one of the handles 14 on the side wall to facilitate pushing the cleaning bucket 1. When changing the direction of movement, the other handle 14 on the side wall can be held for easier use.

[0031] Please see Figure 3 The preferred embodiment of this utility model also provides a coating roller cleaning device, including a frame 6, a scraping component 7, and a coating roller scraper slurry suction device as described above. The scraping component 7 is installed on the frame 6 and is used to scrape off the slurry adhering to the surface of the coating roller. The suction end of the air gun suction component 32 is located between the scraping component 7 and the coating roller. The air gun suction component 32 can suck the slurry scraped off by the scraping component 7 into the cleaning bucket 1, thus solving the problem of inconvenient cleaning of the coating roller.

[0032] Specifically, the scraping assembly 7 includes a scraper 71 and a scraper drive 72. The fixed end of the scraper drive 72 is mounted on the frame 6, and its moving end is connected to the scraper 71. When the coating roller needs to be cleaned, the scraper drive 72 drives the scraper 71 to stick close to the surface of the coating roller to scrape off the residual slurry on the surface of the coating roller. After cleaning, the scraper drive 72 drives the scraper 71 away from the coating roller to prevent the scraper 71 from hindering the coating roller from coating the electrode.

[0033] In this embodiment, the scraper drive component 72 includes a cylinder 721. The cylinder body of the cylinder 721 is mounted on the frame 6, and its piston rod is connected to the scraper 71. The cylinder 721 has a simple structure and can realize the linear reciprocating motion of the scraper 71 at high frequency, which facilitates the switching between coating and cleaning states of the coating roller.
