Description
Technical field
The invention belongs to paper making equipment technical field, relate to a kind of paper injection band shaping equipment, the paper injection band obtaining performance the best that conveniently those skilled in the art are simple and quick simultaneously, present invention also offers a kind of method for shaping of paper injection band.
Background technology
After current paper goes out drying section, calecder section need be transported to by paper injection band.Paper injection band just need can play the effect of conveying page after sizing.If paper injection band is without sizing, one is that paper injection band itself easily produces wrinkle, and when paper injection, page easily produces discounting in the position of paper injection band, produces paper defects, affects product percent of pass; Two is requirements that the air permeability of paper injection band does not reach technique, and in the process of paper injection, page can not be flattened on paper injection band, and page easily hikes up, and causes easy difficulty, and even disconnected paper, affect the operation ratio of paper machine, increase production cost.Three are unshaped paper injection bands is can deform and extend in process of production, and the paper injection band after elongation sideslip will occur in running, the phenomenons such as discounting, affects the normal production of paper machine.
Instantly, shape to paper injection band, effect is unsatisfactory, show that the air permeability of paper injection band cannot meet needs of production, and paper injection band is insufficient owing to shaping, be often in operation generation sideslip, the phenomenon given a discount, brings larger technology barrier to the production practices of those skilled in the art.
Summary of the invention
Technical problem to be solved by this invention is that existing paper injection band cannot meet need of production, be in particular in that the air permeability of paper injection band does not reach requirement, the sizing degree of paper injection band cannot be held, the more important thing is that air permeability and the paper injection band degree of sizing cannot the coordinating and unifyings, even if thus the requirement of actual production also cannot be met through the paper injection band of sizing.To this, the invention provides a kind of paper injection band shaping equipment, this device comprises support platform, be fixed on the fixed roll wheel in support platform, the sliding seat that support platform is slided, be fixed on the travel mechanism of action roller wheel on sliding seat and mobile sliding seat.Paper injection band is enclosed between fixed roll wheel and action roller wheel, then starts travel mechanism, just can shape to paper injection band.Those skilled in the art can adjust speed and the moving displacement that travel mechanism moves sliding seat, thus at least can adjust the sizing degree of paper injection band, adjust the air permeability of paper injection band simultaneously.Adopting roller arrangement to shape to paper injection band is that the present invention recommends, running roller is dispersed on paper injection band uniformly to the active force of paper injection band in paper injection band type-approval process, and can by rotating the frictional force (namely there will not be certain section of paper injection band transition to shape, and another section of paper injection band being shaped inadequate situation) discharging two running rollers timely and produces paper injection band.
Improve as one, invention also contemplates that paper injection band rolls along with running roller, the accident of generation, such as paper injection band occurs slide at roller surface and produce to be displaced sideways and wander off, once this thing happens, whole paper injection band sizing will be given up halfway.
If paper injection band rotates in type-approval process on running roller, the cornerite making paper injection band at roller surface strengthens by the excessive running roller of diameter, strengthen the normal pressure between paper injection band and running roller, strengthen the frictional force of paper injection band and roller surface, this can make paper injection band slide and generation is displaced sideways and wanders off at roller surface; The running roller that diameter is less, to paper injection band be made less at the cornerite of roller surface, reduce the normal pressure between paper injection band and running roller, thus the frictional force between paper injection band and running roller is reduced, when have certain side direction wander off component time, will make paper injection band wander off phenomenon strengthen.In fact, for the paper injection carrying material (such as polynary ester etc.) that paper industry is common, fixed roll wheel and action roller wheel diameter can be set as 140mm-160mm, and fixed roll wheel is controlled at 0.02-0.04 with the skin-friction coefficient of action roller wheel (fixed roll wheel and action roller are taken turns identical to the skin-friction coefficient of paper injection band), the phenomenon of paper injection band sideslip substantially can not occur within the scope of this.Be enclosed within by paper injection band on fixed roll wheel and action roller wheel, through several times test, the probability of paper injection band sideslip is within 5%.
The method of further reduction sideslip probability limits the position of fixed roll wheel and action roller wheel, and levelness and the perpendicularity deviation of fixed roll wheel and action roller wheel control within 1mm.
Preferred as one, fixed roll wheel and action roller wheel diameter are set in 147mm-156mm, the fixed roll wheel that the present invention recommends more and action roller wheel diameter scope are 149mm-153mm, preferred as one, the skin-friction coefficient of fixed roll wheel and action roller wheel is 0.027-0.036, and the fixed roll wheel that the present invention recommends more and the skin-friction coefficient of action roller wheel are 0.029-0.032.
Paper injection band is in the process completing sizing, air permeability also can change, in some cases, such as take turns at the too fast Ye Ji travel mechanism of the sizing action roller that movement is positioned on sliding seat fast, the change of air permeability is obvious, amplitude of variation is often huge, but in fact, paper industry is specific often to the demand of paper injection band, quick mobile action roller wheel is shaped to paper injection band, be to lose required air permeability once large technological deficiency, and the sizing of paper injection band is often irreversible, the paper injection band quality after this just makes sizing does not reach set requirement.More main technological deficiency is that paper injection band microstructure is moving in the process stretched fast, and suffer the destruction of inhomogeneities, cause the paper injection band gas permeability after sizing to be uneven, such paper injection band does not have value equally in actual paper.
The present invention is for the consideration of the technical problem reflected above-mentioned production practices, and suggestion those skilled in the art be further improved displacement mechanism, and such as those skilled in the art can adopt following two schemes:
The first scheme be make described travel mechanism comprise at least one be fixed on Dished spring on sliding seat, with the relatively-stationary tooth bar of support platform and worm screw, described Dished spring, tooth bar and worm screw mate mutually, described support platform is provided with screwed hole, and worm screw one end is provided with the spiro rod section mated with screwed hole.Rotate rolling worm screw to drive Dished spring, action roller is pulled to take turns by pulling sliding seat, also axially-movable is there is in the rotation process of worm screw, described axially-movable produces after being positioned at the spiro rod section of worm screw one end and screwed hole acting in conjunction, and the speed of described axially-movable is equal with the translational speed that action roller is taken turns.
First scheme be make described travel mechanism comprise at least one be fixed on rolling bearing on sliding seat, with the relatively-stationary tooth bar of support platform and at least one travelling gear, described rolling bearing, tooth bar and travelling gear mate mutually.Rotating travelling gear can drive rolling bearing to roll, and pulls action roller to take turns by pulling sliding seat.
The present invention tends to the first scheme more, adopt the program, at least do not need extra to set up parts to offset the pulling force of paper injection band to Dished spring, achieve mobile and stop mobile in real time and do not need additional tensions to offset the technique effect of paper injection tensile force of belt in real time.
In general, above-mentioned two schemes all creates the technique effect that a present invention earnestly wishes to obtain, namely can regulate travel mechanism, the translational speed that action roller is taken turns is within a slow scope (such as within 25mm/s), significantly limit the amplitude of variation of the translational speed of action roller wheel, to adapt to the reality need of paper injection band sizing.
Certainly, only there is the shaping equipment of paper injection band of the present invention, still can there is suitable technical difficulty to the sizing of paper injection band in technical staff, be in particular in: 1, cannot according to the degree of paper injection band sizing, adjust the translational speed of action roller wheel timely, the present invention finds, in the process of paper injection band sizing, all the time adopt same translational speed, still can produce uneven destruction to paper injection band microstructure.2, the sizing degree of paper injection band and air permeability cannot be made to reach instructions for use all simultaneously, a kind of phenomenon often occurred at present is, the air permeability of paper injection band meets the requirements generally, but the sizing of paper injection band not, causes paper injection band in use also can extend further.
At least in view of the technical problem of above two aspects, the invention provides a kind of method for shaping of paper injection band, the method comprises:
A, step paper injection band is enclosed within fixed roll wheel and action roller wheel;
The step of b, mobile action roller wheel;
C, paper injection band air permeability detecting step;
Described b step comprises;
1, the step of quick mobile action roller wheel;
2, the step of action roller wheel translational speed is regulated;
Described 2 steps comprise:
First stage: when the percentage elongation of paper injection band is less than 0.12%, regulate action roller wheel translational speed to 14-25mm/s;
Second stage: when paper injection band percentage elongation is more than or equal to 0.12% and is less than 0.23%, regulates action roller wheel translational speed to 8-13mm/s;
Phase III: when paper injection band percentage elongation is more than or equal to 0.23% and is less than 0.37%, regulate action roller wheel translational speed to 3-7mm/s;
Fourth stage: when paper injection band percentage elongation is more than or equal to 0.37% and is less than 0.49%, regulates action roller wheel translational speed to 1-3mm/s;
Five-stage: when paper injection band percentage elongation is more than or equal to 0.49% and is less than or equal to 0.55%, regulates action roller wheel translational speed to 0-1mm/s.
The sizing degree of paper injection band generally can be characterized by paper injection band percentage elongation, the present invention finds through overtesting, general paper injection band needed in 2 steps usually through several stage, need to use different translational speeds in each stage, an obvious technique effect of such setting is that paper injection band microstructure changes in the process of sizing, although these change because the reason of paper injection band own material is irreversible, but the change of paper injection band structure is uniform, thus at least can obtain the uniform paper injection band of gas permeability.Should be noted that, those skilled in the art do not need various different types of paper injection band all through the process in 2 steps 5 stage, in fact, the present invention is also provided with paper injection band air permeability detecting step, implement in the process that this step is carried out in 2 steps, technical staff can stop 2 steps timely according to testing result, in order to when implementing paper injection band air permeability detecting step, cause the unpredictalbe destruction of paper injection band microstructure, the present invention advises that described step c comprises the step that 2 steps carry out detecting paper injection band with tension detecting instrument in process and the termination step in good time stopping 2 steps according to testing result, described to paper injection band detect step comprise by 2 steps action roller wheel translational speed be adjusted to zero, start permeating degree tester, paper injection band is detected, the adjacent time interval performing step c for twice is 3-6s.
The described termination step in good time stopping 2 steps according to testing result comprises and testing result and paper injection band typed data index being contrasted, and when testing result and paper injection band typed data index difference are less than or equal to 1%, stops 2 steps; When testing result and paper injection band typed data index difference are more than 1%, regulate that action roller wheel translational speed is even accelerates to the speed before detection, continue execution 2 step.Preferably, the action roller wheel displacement that even acceleration produces is less than 1mm, to prevent from producing too much sizing change in even accelerator.
In addition, in the stage that 2 steps are different, general adopt different action roller wheel translational speeds, for guaranteeing that paper injection band is breathed freely the consideration of the uniformity, the present invention's suggestion arranges changeover portion in first to fourth latter stage in stage, specifically:
In latter stage first stage, the even deceleration of first stage action roller wheel translational speed is adjusted to the First Transition of second stage action roller wheel translational speed;
Latter stage the even deceleration of second stage action roller wheel translational speed is adjusted to the second transition that translational speed taken turns by phase III action roller in second stage;
In latter stage phase III, the even deceleration of phase III action roller wheel translational speed is adjusted to the 3rd transition of fourth stage action roller wheel translational speed;
Latter stage the even deceleration of fourth stage action roller wheel translational speed is adjusted to the 4th transition that translational speed taken turns by five-stage action roller in fourth stage.
Refer to the time period of after each stage at the most 1/3rd described latter stage in stage, such as, after 1/8th time periods etc.
The trickle stretching of stage backward to paper injection band brings the change of larger sizing quality index, best sizing index is obtained least for not missing, general, the present invention advises that the action roller wheel displacement that described even acceleration produces is less than 1mm, and the action roller wheel displacement that the even deceleration of First Transition produces is less than 50mm, the action roller wheel displacement that the even deceleration of second transition produces is less than 15mm, the action roller wheel displacement that the even deceleration of 3rd transition produces is less than 5mm, and the action roller wheel displacement that the even deceleration of the 4th transition produces is less than 1mm.
Generally speaking, the method for shaping of a kind of paper injection band of the present invention is applicable to the paper injection band of field of papermaking routine use, and such as thickness is paper injection band be made up of Kynoar of 1.5mm etc.
Use the method for shaping of paper injection band of the present invention, the fixed effect of paper injection band can be improved greatly, reduce the generation of sizing failure scenario greatly.Paper injection band is shaped under power (also namely paper injection band meets instructions for use about air permeability and sizing degree) reaches the prerequisite of 98.7%, is consistent before can ensureing the uniformity of paper injection band after shaping and sizing.
