Paper-making mesh portion slitter edge stabilizer
Technical Field
The utility model belongs to the papermaking equipment field, concretely relates to paper making mesh portion slitter edge stabilizer.
Background
The paper sheet of the paper machine is transferred from the net part to the press part mainly through a vacuum suction roller, but the waste edge cut by the edge fixing water needle of the net part enters the press part along with the whole paper, so that the paper sheet is broken, and the production efficiency of the paper machine is seriously influenced. In order to solve the problem of 'band edge' of waste paper edge, a waste edge stabilizing device is generally arranged below the suction roller to enable the waste paper edge to enter a waste paper pool.
The traditional waste edge stabilizing device adopts a negative pressure suction structure, and a high vacuum area is formed locally under the action of negative pressure, so that waste paper edges are attached to a forming net, the structure is complex, and the energy consumption is high; and the ceramic panel on the box body rubs with the forming net for a long time, so that the forming net is abraded, and the service life of the forming net is shortened.
