However, during the long filtration process, particulate matter can adhere to the inner wall of the filter, causing it to clog. Existing cleaning methods typically require manual removal of the outer shell for cleaning, a cumbersome and inefficient process. If particulate matter is not promptly removed, it will affect the normal filtration effect.

[0004] Therefore, a kind of anti-blocking laser cutting machine filter is needed. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1: A filter for anti-blocking laser cutting machine, see Figure 1-Figure 5 , including a lower shell 1, an upper shell 2, an air intake pipe 3, an exhaust pipe 4, a drainage duct 5, a screen pipe 6 and a bottom cover 601. The lower part of the upper shell 2 is clamped with the lower shell 1. Four mounting holes 201 are opened on the left and right sides of the upper shell 2. The mounting holes 201 are used to insert the screw rods and then connect multiple filters. The upper shell 2 is provided with an air intake pipe 3, the upper shell 2 is provided with an exhaust pipe 4, the bottom of the lower shell 1 is connected with a drainage duct 5, the lower part of the air intake pipe 3 is threaded with a screen pipe 6, the lower end of the screen pipe 6 is plugged with a bottom cover 601, and the upper shell 2 is provided with a screw connection. A motor 7 is provided, and an inclined scraper 8 is connected to the output shaft of the motor 7. The inclined scraper 8 is located inside the screen tube 6. Two transparent plates 15 are embedded in the lower shell 1, and the transparent plates 15 are used to facilitate viewing the condition of the screen tube 6. Sealing rings 16 are embedded on both sides of the upper shell 2. The sealing ring 16 increases the sealing between the upper shell 2 and other upper shells 2 to prevent exhaust gas leakage. A protective cover 17 is fixedly connected to the upper shell 2, and the motor 7 is located inside the protective cover 17. The protective cover 17 protects the motor 7 to prevent damage to the protective cover 17 caused by external factors.

[0023] When it is necessary to use a laser cutting machine filter, first install the primary filter, medium efficiency filter and high efficiency filter at the appropriate position of the laser cutting machine. The exhaust gas generated during the laser cutting process is sucked into the air intake pipe 3 through the fan or exhaust system, and the exhaust gas enters the screen tube 6. The screen tube 6 filters the particulate matter and harmful gases carried in the exhaust gas. Each level of the filter is responsible for removing particulate matter and harmful gases of different sizes. The clean air after multi-stage filtration is discharged into the external environment through the exhaust pipe 4. After using the laser cutting machine filter for a long time, the particulate matter will adhere to the inner wall of the screen tube 6, causing the screen tube 6 to be blocked. At this time, the motor 7 can be turned on, and the output shaft of the motor 7 rotates to drive the inclined scraper 8 to rotate, thereby scraping off the particulate matter attached to the inner wall of the screen tube 6, so as to achieve the purpose of automatic cleaning, improve the cleaning efficiency, and avoid particulate matter adhering to the inner wall of the screen tube 6, causing it to be blocked, thereby affecting normal filtration.

[0024] Example 2: Based on Example 1, please refer to Figure 4A first fixing plate 10 is fixedly connected to both sides of the screen tube 6, and a connecting plate 9 is provided on the bottom cover 601 by bolt connection. Two first limiting rods 11 are inserted into the connecting plate 9, and the first limiting rod 11 passes through the first fixing plate 10.

[0025] When the exhaust gas is filtered, the connecting plate 9 performs secondary fixation on the bottom cover 601 to prevent the bottom cover 601 from loosening and falling off due to excessive air pressure.

[0026] See also Figure 5 A top rod 12 is slidingly provided at the bottom of the lower shell 1, and the top rod 12 is clamped with the screen tube 6. A second fixed plate 13 is fixedly connected to the bottom of the lower shell 1, and a second limiting rod 14 is slidingly provided on the second fixed plate 13. The second limiting rod 14 passes through the top rod 12 and limits the top rod 12.

[0027] When the screen tube 6 needs to be cleaned, first pull the second limiting rod 14 forward to disengage it from the push rod 12, then pull the push rod 12 downward to remove it from the lower shell 1, and then disassemble the lower shell 1 and the screen tube 6 in turn to clean the screen tube 6. After cleaning, first fix the screen tube 6 on the air intake pipe 3, then install the lower shell 1 back on the upper shell 2, and then insert the push rod 12 into the bottom of the lower shell 1 to limit the screen tube 6, thereby preventing the screen tube 6 from loosening and falling off. Finally, push the second limiting rod 14 backward to make it pass through the push rod 12, thereby limiting the push rod 12.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
