Detailed Description
The technical solution of the present invention will be further explained with reference to the following embodiments and accompanying drawings.
As shown in fig. 1, the water needle paper guiding device of the drying part of the paper machine comprises:
the two machine frames are symmetrically arranged and respectively comprise a left machine frame 11 and a right machine frame 12, and a space for paper to pass through is formed between the two machine frames;
the water needle 20 is movably arranged on the left frame 11, the water needle 20 sprays high-pressure water flow towards the paper to penetrate through the paper, and the high-pressure water flow is perpendicular to the paper surface and faces one side of the left frame 11;
a suction box 30 movably mounted on the right frame 12, the suction box 30 being capable of receiving the high-pressure water flow sprayed from the water needle 20 and delivering the high-pressure water flow to the collection tank 37;
and a controller (not shown in the figure) connected to the water needle 20 and the suction box 30, respectively, and capable of driving the water needle 20 and the suction box 30 to move along the corresponding frames to draw the paper.
In actual paper production, paper is often fed by a paper feeding cutter, and the paper is cut from one side of the paper to the other side of the paper by the cutter while being conveyed, so that the paper feeding operation of the whole paper is realized. However, when the existing paper guiding cutter is used for cutting, paper hair and fragments are easy to generate, the production of paper is not facilitated, the surface of a drying cylinder and related equipment are affected, the production quality is relatively poor, and the production is not ideal enough; in addition, the temperature of the drying part is relatively high, so that certain influence is exerted on the use of the cutting knife made of metal materials, the risk of paper breaking is caused, and smooth production is not facilitated.
Therefore, the utility model provides a paper machine drying part's water needle draws paper device through the cooperation setting of water needle 20 and suction box 30, realizes drawing paper to the cutting of paper, and high-pressure rivers cutting paper is less relatively and not have deckle edge, piece scheduling problem to the harm of paper and produces, and the cutting draws paper effectually.
Specifically, in operation, paper moves between the two frames along with other paper machine equipment, the water needle 20 sprays high-pressure water flow towards the paper, the high-pressure water flow keeps an angle perpendicular to the paper and continuously penetrates through the paper, the contact between the high-pressure water flow and the paper can be regarded as point contact, and in a moving state of the paper, the point contact is a line, namely, the high-pressure water flow forms a linear cutting line on the paper, so that the purpose of cutting the paper is achieved.
In this process, the suction box 30 absorbs the high-pressure water flow into the box body under the action of the vacuum pipe 31, and further conveys the high-pressure water flow to the collection tank 37, so that the water flow can be reused, and the waste of resources is avoided, wherein the collected water flow can not be used as clean water any more and can be converted into other water flows.
When the squirt 20 cuts the paper to a certain extent, a controller drives the squirt 20 and the suction box 30 to move from one end to the other end along the respective frames, so that the paper is guided. At this time, since the paper and the water needle 20 move respectively, the high-pressure water flow forms an inclined cutting track on the paper, the paper web on one side is gradually reduced, and the paper web on the other side is gradually increased until the whole width is reached, and the paper guiding work is completed.
