[0003] Among them, the papermaking net is one of the essential equipment of the paper machine. It is a key medium for paper web forming and dewatering, and plays a decisive role in the quality of the formed paper. Specifically, the functions of the papermaking net include: 1. Uniform dewatering; 2. Forming a uniform wet paper web; 3. Driving other components of the wire section to operate.

[0004] After the papermaking net is used for a long time, a large amount of paper scraps will adhere to its surface. In order not to affect its secondary use, the papermaking net needs to be regularly cleaned. Conventionally, on the market, it is cleaned by a high-pressure nozzle, but such a cleaning method is difficult to control the splashing water stains and paper scraps, which are very likely to splash onto the cleaned papermaking net. Therefore, we propose a papermaking net cleaning device for papermaking to solve the above problems, which can concentrate and collect the splashing water stains and paper scraps.

[0024] The cleaning and collecting mechanism includes a water spray box 13 installed on the inner side of the first cleaning box 1 and the second cleaning box 11, a mounting base 2 fixedly installed on both sides of the first cleaning box 1 and the second cleaning box 11, a rotating shaft 21 rotatably installed inside each set of mounting bases 2, a baffle 22 fixedly installed on each set of rotating shafts 21, and a negative pressure cover 23 connected and installed on the inner side of each set of baffles 22. The other end of each set of negative pressure covers 23 is connected and installed with a negative pressure pump. The two sets of water spray boxes 13 are connected and installed with a water source through a water pipe 33 respectively. The four sets of baffles 22 correspond to the papermaking net. The inner walls of the two sets of water spray boxes 13 are connected and installed with multiple sets of equidistantly distributed high-pressure nozzles. The side walls of the four sets of mounting frames 12 are fixed A motor 3 is installed, and four groups of motors 3 are respectively connected to four groups of transmission shafts, and the four groups of transmission shafts are respectively fixed to one end of four groups of rotating shafts 21. By connecting to the water source on the water pipe 33, the high-pressure nozzles on the two groups of water spray boxes 13 will perform high-pressure flushing on both sides of the papermaking net. At the same time, when driving the motors 3 on the four groups of mounting seats 2, the angles of the baffles 22 on the inner sides of the four groups of mounting seats 2 are adjusted, and the ends of the four groups of baffles 22 are all attached to the papermaking net. When driving the negative pressure pump to deliver negative pressure to multiple groups of negative pressure covers 23, the water stains and paper scraps flushed by the high-pressure nozzles are concentrated and recovered through the baffles 22 and the negative pressure covers 23, so as to avoid the papermaking net being adhered to by the flushed paper scraps again after flushing, thereby affecting the cleaning efficiency of the papermaking net.

[0025] Furthermore, splash guards 24 are fixedly installed on the inner walls of the four groups of baffles 22. The multiple groups of splash guards 24 are distributed outside each negative pressure hood 23. When the high-pressure nozzles on the two water spraying boxes 13 are driven to conduct high-pressure flushing on both sides of the papermaking net, a large amount of water stains and paper scraps will fly everywhere. At the same time, in cooperation with the baffles 22 and the splash guards 24, the splashing water stains and paper scraps can be gathered, effectively preventing the paper scraps after flushing from adhering to the surface of the papermaking net after cleaning.

[0026] Furthermore, limiting grooves 32 are formed in the inner walls of the first cleaning box 1 and the second cleaning box 11.

The first cleaning box 1 and the second cleaning box 11 can be fixed through the two mounting brackets 12, and the papermaking net is at a certain distance from the first cleaning box 1 and the second cleaning box 11 respectively, without affecting the normal use of the papermaking net.

[0028] During use, first, by driving the electric push rods 31 on the side walls of the first cleaning box 1 and the second cleaning box 11, the water spraying boxes 13 in the two limiting grooves 32 can be pushed, so that the high-pressure nozzles inside the two water spraying boxes 13 continuously approach the papermaking net. After connecting the water source on the connecting water guide pipe 33, the high-pressure nozzles on the two water spraying boxes 13 will conduct high-pressure flushing on both sides of the papermaking net. At the same time, when driving the motors 3 on the four mounting seats 2, the angles of the baffles 22 inside the four mounting seats 2 are adjusted, and the ends of the four baffles 22 are all attached to the papermaking net. When driving the negative pressure pump to convey negative pressure to the multiple negative pressure hoods 23, the water stains and paper scraps flushed by the high-pressure nozzles are concentrated and recycled through the baffles 22 and the negative pressure hoods 23, preventing the papermaking net after flushing from being adhered by the paper scraps after flushing again and affecting the cleaning efficiency of the papermaking net. At the same time, splash guards 24 are fixedly installed on the inner walls of the four groups of baffles 22, and the multiple groups of splash guards 24 are distributed outside each negative pressure hood 23. When the high-pressure nozzles on the two water spraying boxes 13 are driven to conduct high-pressure flushing on both sides of the papermaking net, a large amount of water stains and paper scraps will fly everywhere. At the same time, in cooperation with the baffles 22 and the splash guards 24, the splashing water stains and paper scraps can be gathered, effectively preventing the paper scraps after flushing from adhering to the surface of the papermaking net after cleaning.

[0029] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
