Abstract

The utility model relates to the improvement of the Yangge type paper-making machine, which adopts the long net layout (Chinese patent 87102984) of the level arranging type of a plurality of the long nets, and a fiber labyrinth shaper (Chinese patent 87102985) is additionally provided. The complete machine is dragged by the rotation of a drying cylinder; the whole operating range of the paper web has no bearing traction, and a shaping net is provided with a facing roller. The Yangge type paper-making machine has simple structure and is suitable for the production of paper. Of 18 to 100 gram/meter +[2].

Description

Single-or Double-long net paper making machine with single cylinder

The invention belongs to the complete paper machine, particularly separate unit fourdrinier wire of making continuous webs of paper, the improvement of raising the blank machine of Yankee dryer.

Raising the blank machine is that the citation form of its structure as shown in Figure 2 by director's net former and the paper machine that big drying cylinder is a capital equipment.The shortcoming of this type is that the wet web on the forming net is outstanding subsides state when transferring on the band paper felt, the easy phenomenon of bursting influences quality of finished paper and production continuously, and another shortcoming is that three groups of independently movement systems are arranged in the complete machine, be not easy coordinate synchronization, so disconnected paper situation takes place easily.

The design's purpose is the improvement design by each part device layout of complete machine, solves wet web and is holding the partly disconnected paper problem of inharmonious generation of the problem of bursting on the paper felt and Yin Ge operation.

The design's content is that one or two director's net formers are arranged in band paper felt upper horizontal, and the shaped segment afterbody of forming net presses between upper and lower couch roll with band paper felt, and wet web is by being with paper felt support to enter squeezing; Second felt is as squeezing top felt, being pressed by the snub pulley support with big drying cylinder, and complete machine holds the paper position and rotated as drawing force by drying cylinder, respectively holds the paper position according to pressing transmission operation power.Be inside and the presentation quality that improves into paper, the lost former (No. 87102985, Chinese patent) of dress fiber is installed pulp roller or water streak roller on forming net between the mouth spray of former head box and forming net.

Embodiments of the invention as shown in Figure 1.

Fig. 1 is the complete machine layout of complete machine of the present invention, wherein:

Fourdriner forming device 1, lost former 2, suction flat box 3, pulp roller 4 holds paper felt 5, grooved press 6, band paper felt (squeezing top felt) 7, carrying roller 8, felt is upheld roller 9, squeeze roll 10, deflector roll 11, washer box 12, big drying cylinder 13, scraper 14, oiling roller 15, paper carrying roll 16, page 17, rotary machine 18.

The fourdriner forming device of the present invention's design can adopt another patent of invention of applicant: horizontally arranged multiple fourdrinier paper machine (No. the 87102984th, Chinese patent), the version of middle design.Two director's net formers are horizontal, hold paper felt support wet web and enter squeezing, pressing device can adopt another patent application case of applicant: press device of paper-making machine (Chinese patent application number 88201313), paper web is through transferring to behind the press dewatering on second felt, and transfer on the drying cylinder at snub pulley and the drying cylinder place of pressing, enter chart drum by drying cylinder then.

On the fourdriner forming device, the lost former (No. 87102985, Chinese patent) of dress fiber is established pulp roller on forming net between mouth spray and forming net, also can be changed to water streak roller.

The present invention's design is compared with the ruled paper machine of raising before improving, and obvious advantage is arranged. At first, before squeezing, wet web does not have outstanding to be affixed on the situation of holding paper felt, the situation of can not bursting. Simultaneously complete machine respectively holds the paper position and realizes dragging transmission according to pressing mode, and with drying cylinder as unique drive source, full machine holds paper and partly realizes synchronous operation, and the disconnected paper situation that causes because transmission is inharmonious can not take place. Owing to cancelled the independent operating dynamical system of former and felt, made complete machine simple in structure. And lower felt also can be in the upper installation of Horizon, need not consider to give to establish the groove hole again. At the drying cylinder position of washing one's face liquid-soaked multi-blade scraper (Chinese patent application number 87104747) is installed, last rotary machine can adopt the rotary machine that the applicant invents (Chinese patent application number 88208174) coil paper. The omnidirectional arrangement situation of fiber when adding the lost former of fiber and can improve the cloth slurry. Adopt the design's paper machine operation Omnidistance nothing stretches, and can stablize to keep the fiber interweaving structure. The design's paper machine can use by two nets simultaneously, also can use single net. As long as loosen the former lower couch (roll), lift top couch (roll), disengage just can make former and hold paper felt.

Paper machine of the present invention is suitable for producing quantitative 18～100 grams/rice²Many kinds paper, such as tissue paper, fruit paper, onionskin, copy paper, typographic printing paper, offset paper, single face coating (silicon, mould) and extrusion coating paper (paper is aluminium foil) etc.

Claims

1, a kind of complete machine of making continuous webs of paper, particularly raise the improvement of form list Fourdrinier yankee machine, comprise one or two director's net formers, big drying cylinder and band paper felt, it is characterized in that one or two director's net formers are above band paper felt, horizontally, the shaped segment afterbody of forming net and band paper felt press between upper and lower couch roll, and wet web enters squeezing by band paper felt support; Second felt is pressed by the snub pulley support with big drying cylinder as the squeezing top felt; Complete machine holds the paper position and is rotated as drawing force by drying cylinder, respectively holds the paper position and transmits operation power according to pressing.

2, according to the described complete machine of claim 1, it is characterized in that outside the head box mouth spray, the lost former of fiber is set before the forming net, pulp roller or water streak roller are arranged on forming net.
