Description

Horizontal stretcher for paper making

The utility model relates to the novel device paper grade (stock) reinforcement cross directional stretch machine used on a kind of paper industry.

Paper industry is one of important industry, the paper application of being produced is among all trades and professions such as life, production, but, the needed high strength paper of some department generally is to add reinforcement material in paper-making process, after the Chemical Pretreatment typing, is added between the two-layer paper pulp, and because reinforcement material (as fiber web) is unstretched, make the retractility of paper be lower than the retractility of reinforcement material, cause paper, do not have the effect of reinforcement prior to the reinforcement material breakage.

The purpose of this utility model is the reinforcement cross directional stretch machine that a kind of paper grade (stock) is provided at above-mentioned situation, to solve in paper-making process, reinforcement material is combined with paper pulp by the back that fully stretches, when making the high strength paper of producing in use stressed, the reinforcement fiber is mainly stressed, thereby improve the bulk strength of paper greatly, improve the quality of paper, increase use value.

The purpose of this utility model is achieved like this, the requirement lateral stressed according to paper, adopt two merit positions reinforcement base material unreeling structure, camber lateral magnification device, horizontal main expander of dish-type and pressing dehydrated structure, and be equipped with fix a breakdown shut-off mechanism and automatic electromagnetic edge guide, to guarantee the safety of equipment, use automatically.

The utility model of this structure is easy to use, and the papermaking quality is good, long service life, remarkable in economical benefits.

Below in conjunction with accompanying drawing structure of the present utility model and operating position are elaborated.

Fig. 1 is the utility model structural perspective.

Fig. 2 installs and uses state diagram for the utility model.

Fig. 3 is that the horizontal main expander of dish-type uses the expansion situation map.

By shown in Figure 1, its structure of the utility model is, two merit positions reinforcement base material unreeling structure 1 is housed on the guide rail 7, promptly two rod structures, its objective is continuously, stably send, after a volume base material uses up, move manual handle used reinforcement fiber mesh cloth 8 in the papermaking, another volume base material is risen to unreel the merit position, change blank coil simultaneously; The shut-off mechanism 2 of fixing a breakdown that upper and lower roll constitutes is housed on then frame 9 on the unreeling structure 1, purpose is when breaking down in the running of paper machine, can in time cut off reinforcement base material screen cloth, it is reinforcement fiber mesh cloth 8, avoid loss, shut-off mechanism 2 is to be made of upper and lower roll, be equipped with cutoff tool 11 on the lower roll, handle 10, top roll plays the deflector roll effect when operate as normal, the distance that 5 millimeter are arranged between the upper and lower roll is shaken lower roll wind 10 when equipment breaks down, make the cutoff tool 11 on the lower roll act on cut-out reinforcement fiber mesh cloth 8 simultaneously with top roll; Frame 9 both sides are equipped with automatic electromagnetic edge guide 3, its objective is the position of control reinforcement fiber mesh cloth 8 two edges, make screen cloth be convenient to enter the horizontal main expander 5 of dish-type, the automatic electromagnetic edge guide is the product of often selling on the market, be equipped with camber lateral magnification device 4 on one side frame of the horizontal main expander 5 of dish-type, be by wooden convexity of making and the bright and clean cross bar of transitions smooth, its effect is to eliminate the middle fold of screen cloth, screen cloth is tentatively expanded, the horizontal main expander 5 of dish-type has two groups, its objective is and will carry out lateral magnification again through the screen cloth after the camber lateral magnification, its expansion situation is by shown in Figure 3, and every group coils installation by 2 gardens and form, after the installation, edge at a side two gardens of clamping screen cloth dish fits together, and two angle and applying distances that the garden dish tilts can be regulated by regulating fastening bolt; Top, outer side frame limit at the horizontal main expander 5 of dish-type is equipped with pressing, dewatering device 6, by top couch (roll) 6a, the little cylinder mould 6b that dewaters forms down, its effect is after horizontal main expander 5 expansions of screen cloth process dish-type stretch, enter pressing, dehydration, make the reinforcement fiber mesh cloth combine, finalize the design with upper strata paper pulp on the felt 12, the moisture content of discharging in the cohesive process is discharged by the little cylinder mould 6a of dehydration.

The situation of installing and using of the present utility model is by shown in Figure 2, in two-wire (paper) machine, after a net 13 hung up layer paper pulp, paper pulp was with papermaker's felt 12, through the utility model---the pressing in the paper grade (stock) reinforcement cross directional stretch machine 15, the moment of dewatering device, through horizontal expanding, smooth, the reinforcement fiber web after the arrangement conforms to upper strata paper pulp reposefully, and then, just can adopt traditional paper technology to produce the reinforcement high strength paper through 14 starchings of two nets.

Find out by above situation, be passive transmission between each action part of the utility model, action is accurately compact, equipment is easy to use, safe and reliable, simple in structure, cost is low, be easy to former paper machine is transformed, can under the structure situation that does not change original paper machine, directly install the utility model additional, solve the insurmountable all the time hard nut to crack of powder or granule thing packaging material in the every profession and trades such as China's paper shortage and cement, flour effectively, the society and economy benefit is very remarkable, for paper-making industry has been opened up new prospect.
