Abstract

The utility model relates to a paper making machine which comprises a pulp pool, a pulp flowing box, an inclined net former, a press, a drying device, a surface gluing machine, a calender and a paper scrolling device. The paper making machine has the benefits that the structure is simple, the operation is convenient and rapid, dry hot air inside a hot air tube is blown into a drying box body through an air blower to form uniform hot air inside an air distribution system, and then effects of energy economization and power consumption reduction are achieved; due to arrangement of a detection light source of the paper scrolling device, flaws of a finished paper web can be detected in the production process, a finished paper product with the flaws is prevented from being delivered to the market, and the quality of the finished product is improved.

Description

A kind of paper machine

Technical field

The utility model relates to paper making equipment field, particularly a kind of paper machine.

Background technology

Paper machine is that the pulp-water suspended substance that meets papermaking requirement is copied to the machine of making paper through filter screen drainage and formation, mechanical presses dehydration and the process such as dry.Current paper making equipment is of a great variety, but also has some problems, and formation of sheet that some paper making equipments are produced is good not, air permeability is low, and paper quality is poor, and machine inefficiency, produces and brings very large inconvenience to enterprise; Simultaneously, in paper-making process, paper is after squeezer dehydration, approximately still there is the moisture of 60%-70%, drying device reaches the finished product of the mass dryness fraction of 92%-95% after drying afterwards. and drying unit is that the moisture that utilizes dry hot blast to make to be attached to the paper on hot air roll becomes steam and extracts out by air exhauster, but existing drying unit big energy-consuming, drying effect is undesirable.

Utility model content

For the defect existing in prior art, the purpose of this utility model is to provide a kind of paper machine.

For reaching above object, the technical scheme that the utility model is taked is:

A kind of paper machine, comprises stock tank, head box, oblique net former, pressing device, drying unit, surface size press, calender and paper winding device; Described drying unit comprises dries casing, hot air roll, warm-air pipe, air blast, air exhauster, gas distribution system and escape pipe; Described gas distribution system is arranged at the bottom of described oven dry casing; Described air blast is arranged on described warm-air pipe; Described air exhauster is arranged on described escape pipe; Described paper winding device comprises base, winding shaft, detection light source, exit slot and goes out reel; Described go out reel be arranged at the bottom of described exit slot; Described detection light source is arranged at the below of paper.

The beneficial effects of the utility model: simple in structure, simple operation, air blast is sent into the dry-heat air in warm-air pipe to dry in casing, forms uniform hot blast in gas distribution system, thus the effect that reaches energy-conservation, reduces power consumption; The detection light source of paper winding device setting can detect the flaw that in production process, finished product paper web exists, and can avoid being with finished product paper web defective to come into the market, and improves end product quality.
