Abstract
The utility model provides a slitting device for a wet paper web. The slitting device comprises the wet paper web in a moving state. A first squirt is arranged above the wet paper web, the included angle between a nozzle extension line of the first squirt and the wet paper web is 50-70 degrees, and the intersection point of the nozzle extension line and the wet paper web is located in a water absorption box below the wet paper web. The first squirt of the slitting device is obliquely arranged above the wet paper web, water flow ejected by the first squirt obliquely hits the wet paper web, has a small inertia effect on the wet paper web, and cannot cause local thickness increasing, thus the phenomenon that the paper web cracks in rewinding can be fully avoided, the quality of finished paper is improved, and meanwhile operating efficiency of a paper machine is guaranteed.
Description
Technical field
The utility model relates to pulp technology for making paper, is specifically related to a kind of cutting device for wet web.
Background technology
The paper pulp that paper industry comes out from flow box according to the door width of cloth of the paper kind of manufacturing paper with pulp and quantitatively, installs the high pressure liquid drugs injection additional before couch roll, utilize hydraulic pressure that the unnecessary paper web that enters before the drying cylinder is excised, and reduces energy consumption.In actual production, when a paper machine normally moved, its liquid drugs injection position was responsive and very important position, the disconnected paper of press section, even the disconnected paper of drying section, size press or coating machine can be attributed to the trimming defective that trim shower causes.Existing paper machine liquid drugs injection side cut equipment is made up of softening tank, liquid drugs injection pump, pipeline and liquid drugs injection mostly.
Along with the continuous lifting of the Modern Paper Machine speed of a motor vehicle, the wet end of side cut usefulness is also more and more higher to the requirement that liquid drugs injection is cut edge.The current of the present liquid drugs injection that uses are perpendicular to paper web and cut, and current are beaten on wet web, because the effect of inertia wet web can be piled up to both sides, cause local thickness to rise, when rewinding, along with the increase of reel, become the easy explosion of paper, seriously influenced the quality and the yield rate thereof that become paper.
The current that eject from the nozzle of liquid drugs injection should fitly be cut and wear paper web, the nozzle of liquid drugs injection mostly is one at present, if but the thickness of paper web is excessive, the multilayer paperboard of manufacturing paper with pulp particularly, when perhaps the current speed of paper web is very fast, easily cause many paper hairs when adopting single High-Pressure Water to cut paper web at the edge of paper web, influenced the quality that becomes paper; Produced simultaneously paper hair easily be deposited in liquid drugs injection around, influenced the operational efficiency of paper machine.
The utility model content
The utility model will solve above-mentioned deficiency exactly, and a kind of cutting device for wet web is provided, and can cut wet web effectively, improves into the quality of paper.
In order to reach above-mentioned effect, the utility model provides a kind of cutting device for wet web, comprises the wet web that is in mobile status, and the top of described wet web is provided with first liquid drugs injection, and the nozzle extended line of described first liquid drugs injection and the angle of wet web are 50-70 °; The intersection point of described nozzle extended line and wet web is positioned at the suction box of being located at the wet web below.
Neat, smooth for cutting of wet web located, parallel second liquid drugs injection that is provided with in the place ahead of described first liquid drugs injection, the nozzle extended line of described second liquid drugs injection is positioned at the outside of the nozzle extended line of first liquid drugs injection.
More preferably, the angle of the nozzle extended line of described first liquid drugs injection and wet web is 60 °.
The skewed top that is arranged on wet web of the first liquid drugs injection nozzle of the present utility model, the current of its ejection are to beat obliquely on wet web, effect of inertia to wet web is little, can not cause local thickness to rise, thereby paper web produces the phenomenon of explosion can avoid rewinding fully the time.
Excessive for the web thickness of cutting, particularly multilayer manufacture paper with pulp paperboard the time, parallelly be provided with two liquid drugs injections, and second liquid drugs injection is positioned at the place ahead of first liquid drugs injection, for the branch tangent line of paper web, the nozzle extended line of second liquid drugs injection is positioned at the outside of the nozzle extended line of first liquid drugs injection, and namely the nozzle extended line of second liquid drugs injection is positioned at the outward flange that paper web divides tangent line.The current of the nozzle ejection of two liquid drugs injections impact paper web to become 50-70 ° angle with wet web, the fiber mist that prevents or reduced the rebound effect of water and given birth to thereupon, thus can obtain neat side cut.Simultaneously, perfectly the accurate separation of trimming at the paper carrying roll place guaranteed in side cut.
So the Cardboard Paper that the utility model can be manufactured paper with pulp to multilayer when perhaps the current speed of paper web is very fast, can be fitly cut and wear paper web, has improved the quality that becomes paper, has also guaranteed the operational efficiency of paper machine simultaneously.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is first kind of structural representation of the utility model.
Fig. 2 is second kind of structural representation of the utility model.
Among the figure: 1-wet web, 2-nozzle, 3-first liquid drugs injection, 4-suction box, 5-second liquid drugs injection.
The specific embodiment
Embodiment one:
As shown in Figure 1, a kind of cutting device for wet web comprises the wet web 1 that is in mobile status, and the top of described wet web 1 is provided with first liquid drugs injection 3, and nozzle 2 extended lines of described first liquid drugs injection 3 and the angle of wet web 1 are 60 °; The intersection point of described nozzle 2 extended lines and wet web 1 is positioned at the suction box 4 of being located at wet web 1 below.
The skewed top that is arranged on wet web of the first liquid drugs injection nozzle of the present utility model, the current of its ejection are to beat obliquely on wet web, effect of inertia to wet web is little, can not cause local thickness to rise, thereby paper web produces the phenomenon of explosion can avoid rewinding fully the time.
Embodiment two:
As shown in Figure 2, a kind of cutting device for wet web, comprise the wet web 1 that is in mobile status, parallel first liquid drugs injection 3 and second liquid drugs injection 5 of being provided with in the top of described wet web 1, described second liquid drugs injection 5 is located at the place ahead of first liquid drugs injection 3, and its nozzle extended line is positioned at the outside of nozzle 2 extended lines of first liquid drugs injection 3.Nozzle 2 extended lines of two liquid drugs injections and the angle of wet web 1 are 60 °, and the intersection point of nozzle 2 extended lines and wet web 1 is positioned at the suction box 4 of being located at wet web 1 below.
The current of the nozzle ejection of two liquid drugs injections impact paper web to become 60 ° angle with wet web, the fiber mist that prevents or reduced the rebound effect of water and given birth to thereupon, thus can obtain neat side cut.Simultaneously, perfectly the accurate separation of trimming at the paper carrying roll place guaranteed in side cut.The Cardboard Paper that can manufacture paper with pulp to multilayer when perhaps the current speed of paper web is very fast, can be fitly cut and wear paper web, has improved the quality that becomes paper, has also guaranteed the operational efficiency of paper machine simultaneously.
Above embodiment is not limited only to protection domain of the present utility model, all make amendment based on basic thought of the present utility model or change all belong to protection domain of the present utility model.
