A wet paper cutting device

Abstract

The invention belongs to the technical field of wet paper cutting and particularly relates to a wet paper cutting device, comprising a moving frame. A nozzle seat is slidably connected to the moving frame and is fitted with a nozzle, the nozzle is connected with a water pipe, the water pipe is connected with a water supply box through a high-pressure water pump, mesh fabric is disposed below the nozzle and is spread on an adsorbing device, the adsorbing device comprises an adsorbing box, the adsorbing box is internally provided with a water suction cavity, the upper end surface of the adsorbing box is a horizontal surface and is provided ith a plurality of water suction openings in communication with the water suction cavity, the water suction openings are transversely and evenly distributed along the upper end surface of the adsorbing box and are parallel to one another, the adsorbing box is connected with the water supply box through a return water pipe, the return water pipe is provided with a return water pump, and the adsorbing box is also connected with a negative pressure device capable of sucking out air in the water suction cavity. The wet paper cutting device is reasonable in overall design and simple in structure.

Description

technical field [0001] The invention belongs to the technical field of wet paper cutting, and in particular relates to a wet paper cutting device. Background technique [0002] When producing paper on a high-speed paper machine, the wet paper width in the wire section is limited by the mechanical width of the headbox, so the wet paper width must be adjusted arbitrarily with a water knife for production. However, the water jet in the prior art directly drains waste water during the cutting process, which wastes a lot of water resources, and the overall design is not reasonable enough. [0003] In order to improve the existing technology, people have carried out long-term exploration and proposed various solutions. For example, the Chinese patent literature discloses a water jet cutting and recycling device for wet edge paper [application number: CN201320657059.9], which includes a booster water pump, a water jet device connected to the booster water pump through a water jet ...
