Specifically, first clear water shower 1 sets up along forming net 80 width direction level, and equidistant a plurality of first shower nozzles that are equipped with are carried out the clear water and spray to forming net 80 upper surface on first clear water shower 1, a plurality of first shower nozzles.
The second clear water spray pipe 2 is arranged on the left side of the first clear water spray pipe 1, and the second clear water spray pipe 2 comprises a pipe body 20 horizontally arranged along the width direction of the forming net 80, and a first side spray pipe 21 and a second side spray pipe 22 which are arranged at two ends of the pipe body 20 and communicated with each other. First limit portion spray tube 21 and second limit portion spray tube 22 all are L type structure, and the one end of first limit portion spray tube 21 and second limit portion spray tube 22 is connected with body 20 is perpendicular respectively, and the upper end horizontal part parallels with body 20, and impartial interval is provided with a plurality of second shower nozzles on the upper end horizontal part, and a plurality of second shower nozzles set up with first shower nozzle relatively, and a plurality of second shower nozzles carry out the clear water to forming net 80 lower surface promptly and spray. The first clear water spray pipe 1 and the second clear water spray pipe 2 are respectively installed on the bottom rail 20 through bases.
And a double-sided spray pipe 3 is arranged on the left side of the lower net guide roller 70 and is used for spraying and washing the front side and the back side of the forming net 80. Further, the forming net 80 is sprayed and washed again, so that the forming net 80 is completely prevented from carrying the rotten pulp to enter a press area, and the product quality is ensured.
The cutting squirt 50 and the forming net corrector 60 are installed on the bottom rail 30, the lower net guide roller 70 is installed on the frame 40, and the forming net 80 is wound on the forming net corrector 60, the lower net guide roller 70, the guide roller, the driving roller, the steering roller and the forming roller.
The working principle is as follows: the first clear water spray pipe 1 and the second clear water spray pipe 2 are additionally arranged in the area between the forming net corrector 60 of the lower net and the lower net guide roller 70, and the first clear water spray pipe 1 washes the residual slurry fiber on the front surface of the forming net 80 again to ensure the air permeability and the drainability of the forming net 80; after the first clear water spray pipe 1 is washed, the first side spray pipes 21 and the second side spray pipes 22 on two sides of the second clear water spray pipe 2 repeatedly wash and clean the fibers in the residual net of the paper sheets cut by the water needle, so that the fibers fall off and are not attached to the forming net 80. Therefore, no fiber is gathered on the lower wire guide roller 70, the forming wire 80 is not abraded, the service life of the forming wire 80 is prolonged, the forming wire 80 does not carry the rotten pulp to enter a press area, and the product quality is effectively improved.
The present embodiment is not described in detail, and is a technique known in the art.
The above description is only for the specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive various changes or substitutions within the technical scope of the present invention, and these should be covered by the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
