DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-Figure 3A paper machine net replacement device comprises a papermaking table 1, a fixed frame 4 is fixedly connected to the top of the papermaking table 1, the fixed frame 4 is provided with a sliding opening, the bottom of the sliding opening is provided with an opening, the bottom of the fixed frame 4 is provided with a cavity 1, the cavity 1 is connected to the opening, the papermaking table 1 is provided with a cavity 2, a net body 5 is slidably inserted in the sliding opening, an electric telescopic rod 10 is fixedly connected to the bottom of the cavity 2, a driving end of the electric telescopic rod 10 is fixedly connected to a transmission plate 11, and the top of the transmission plate 11 A connecting plate 12 is fixedly connected, and the connecting plate 12 slides through the top of the papermaking table 1 and extends to the cavity 1. A pressing plate 13 is fixedly connected to the top of the connecting plate 12. A papermaking roller 14 is fixedly arranged on the top of the papermaking table 1. Two hollow legs 2 are fixedly connected to the bottom of the papermaking table 1. The length and width of the opening are greater than the length and width of the pressing plate 13. The pressing plate 13 is in contact with the net body 5. The papermaking roller 14 is located on the rear side of the fixed frame 4. The two hollow legs 2 are arranged on the left and right sides of the bottom of the papermaking table 1. The legs 2 can prevent the papermaking table 1 from becoming less sealed due to long-term use, and prevent water splashed by papermaking from falling to the ground and entering the interior through the bottom of the papermaking table 1, thereby extending the service life of the papermaking table 1. The middle of the hollow legs 2 is empty, so personnel can better handle the water under the papermaking table 1. When the net body 5 is placed in the fixed frame 4 through the sliding opening, the transmission plate 11 is moved vertically upward by the electric telescopic rod 10, thereby driving the connecting plate 12 and the pressing plate 13 to move vertically upward. When the pressing plate 13 contacts the net body 5 through the opening, the top of the net body 5 will contact the inner side wall of the top of the sliding opening, and the net body 5 is fixed by extrusion. If the net body 5 is damaged and needs to be replaced, it is only necessary to move the driving end of the electric telescopic rod 10 downward and drive the pressing plate 13 to move downward. When the pressing plate 13 is not in contact with the net body 5, personnel can pull the net body 5 out of the fixed frame 4, thereby reducing the replacement speed and improving work efficiency.

[0020] The fixed frame 4 is symmetrically provided with a constant temperature blowing mechanism, which includes an air blower 3, which is fixedly connected to the outer wall of the fixed frame 4, and the output end of the air blower 3 is fixedly connected with a blowing pipe 6 that penetrates the fixed frame 4, and the outer wall of the blowing pipe 6 is fixedly connected with a ventilation plate 9, and a plurality of air outlets 8 are provided on the top of the ventilation plate 9, and two constant temperature heating pipes 7 are fixedly provided on the inner wall of the fixed frame 4, and the two constant temperature heating pipes 7 are arranged on the left and right inner walls of the fixed frame 4, and a plurality of air outlets 8 are evenly arranged on the outer side of the ventilation plate 9, and the two constant temperature heating pipes 7 are arranged directly above the ventilation plate 9. The main purpose of adsorbing moisture is to quickly separate moisture from the fiber, and fiber is mainly needed for papermaking. When moisture adsorption is needed, the constant temperature heating pipe 7 is started, and the air blower 3 is used to make the wind pass through the blowing pipe 6 and the ventilation plate 9, and finally blown out from the air outlet 8. In conjunction with the constant temperature heating pipe 7, constant temperature wind can be blown out, thereby accelerating the speed of moisture disappearance and improving the efficiency of moisture adsorption.

[0021] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
