Background technology:
Traditional food calendar rolls distance regulating mechanism is unidirectional adjusting form, and lower compression roller is fixed on frame, and the top roll upper-lower position is adjustable.There is mechanical stop limiter the top roll top, and for limiting the limes superiors position of top roll, the top roll below does not have spacing.The position of regulation limiting device, can determine and the extreme higher position of top roll indirectly determine the thickness by wearing between roller.But the top roll below does not have stopping means, be to wear the thrust of being out of shape generation by centre finally to determine its physical location.The roller spacing that this regulative mode forms is worn hardness to be affected greatlyr, if it is less to wear hardness, top roll can not reach the limes superiors position, and the roller spacing is less than normal, and wearing can attenuation, form before will Hou road calendering mechanism wear stacking.And between roller, transmission is gear drive, adjust the roller spacing because of needs, the problem such as the centre-to-centre spacing of two travelling gears also changes thereupon, makes in the gear drive process sideshake larger, thereby causes system noise excessive, and gear life is too short.In addition, this class connects press and adopts a power transmission ,Ge road to connect press mechanism power by the chain transmission, and mechanical efficiency is very low, and fault rate is high, does not possess single track rotational speed regulation function, complicated operation.
Goal of the invention:
The technical problem that the present invention solves: design a kind of food calendar rolls distance regulating mechanism, overcome prior art roller spacing and worn the defect that hardness affects, and changed the kind of drive, improve transmission efficiency and stationarity, make whole calender line thickness controlled, and can be automatically according to wearing soft durometer, adjust between each roller and roll when rotating ratio, guarantee product quality.
Technical solution of the present invention: a kind of food calendar rolls distance regulating mechanism comprise frame, top roll and lower rod, and lower roll is arranged on the below of frame by bearing; The top of described frame is symmetrically installed with a pair of sleeve, the two ends of described top roll by bearing respectively bias be arranged in a pair of sleeve; There is worm gear on the outer face of described sleeve; The top of described frame is symmetrically installed with a pair of worm screw, and worm and wheel is meshed, and described worm screw passes through driven by servomotor.
The axis of described top roll is positioned at the below of the axis of a pair of sleeve.
Described lower rod drives by the direct-connected motor reducer of its right-hand member, and the left end of top roll and lower rod is fixed with respectively passive and synchronous belt wheel and active synchronization belt wheel; The left end of described frame is equipped with two regulating wheels, and regulating wheel is positioned at the below of active synchronization belt wheel, and the active synchronization belt wheel drives passive and synchronous belt wheel by ring-shaped synchronous belt and two regulating wheels and rotates.
Described sleeve and worm gear are structure as a whole.
The advantage that the present invention compared with prior art has and effect:
1, the present invention has realized that the roller spacing regulates automatically, and possesses roller spacing lock function, during the multiple tracks calendaring linkage, can adjust in real time the roller spacing, makes whole calender line thickness controlled, guarantees to wear not produce sideslip, fracture, packing phenomenon when connecting press.
2, the present invention has realized per pass calendering separate transmission, and every pair of pressure roller rotating speed can independently be adjusted as required, has improved transmission efficiency and stationarity, and can be automatically according to wearing soft durometer, adjusts between each roller and roll when rotating ratio, the assurance product quality.
3, between roller of the present invention, transmission adopts toothed belt transmission, has overcome that gear transmission noise is large, the life-span is short and gear grease easily produces the problem of pollution.
The specific embodiment:
1,2,3 a kind of embodiment of the present invention is described by reference to the accompanying drawings.
A kind of food calendar rolls distance regulating mechanism, comprise frame 1, top roll 2 and lower rod 3, and lower roll 3 is arranged on the below of frame 1 by bearing.The top of described frame 1 is symmetrically installed with a pair of sleeve 4, the two ends of described top roll 2 by bearing respectively bias be arranged in a pair of sleeve 4, and make the axis of top roll 2 be positioned at the below of the axis of a pair of sleeve 4; Have worm gear 5 on the outer face of described sleeve 4, the top of described frame 1 is symmetrically installed with a pair of worm screw 6, and worm screw 6 is meshed with worm gear 5, and described worm screw 6 drives by servomotor 7.
Described sleeve 4 is structure as a whole with worm gear 5.Described lower rod 3 drives by the direct-connected variable-frequency motor decelerator 8 of its right-hand member, and the left end of top roll 2 and lower rod 3 is fixed with respectively passive and synchronous belt wheel 9 and active synchronization belt wheel 10; The left end of described frame 1 is equipped with two regulating wheels 11, and regulating wheel 11 is positioned at the below of active synchronization belt wheel 10, and active synchronization belt wheel 10 drives passive and synchronous belt wheels 9 by ring-shaped synchronous belt 12 and two regulating wheels 11 and rotates.
The present invention is according to the eccentric adjusting principle, and servomotor 7 drives worm screw 6, by worm screw 6, drives worm gear 5, and then sleeve 4 is rotated.When sleeve 4 rotates, the axis of top roll 2 moves up and down with respect to sleeve 4 cylindricals, thereby realizes the adjustment of roller spacing.
Continuous calendar in practical application is linked in sequence the present invention together exactly, completes the continuous calendering process.And, due to material physical characteristic difference, require to adjust per pass roller space and pressure roller rotating speed.Such as producing in the continuous calendering process at vermicelli, if between Qian Dao Yu Hou road pressure roller, rotating speed or spacing are not mated and just be there will be tension or the stacking situation worn.The present invention has not only realized per pass calendering separate transmission, and every pair of pressure roller rotating speed can independently be adjusted as required, has improved transmission efficiency and stationarity; And realized that the roller spacing adjusts automatically, and possesses roller spacing lock function, can adjust in real time the roller spacing while making the multiple tracks calendaring linkage, make whole calender line wear thickness controlled, and can be automatically according to wearing soft durometer, adjust between each roller and roll when rotating ratio, assurance does not produce sideslip, fracture, packing phenomenon while wearing by company's press, guarantees product quality.
Above-described embodiment, be preferred embodiment of the present invention, not is used for limiting the scope of the present invention, therefore all equivalent variations of being done with the described content of the claims in the present invention all should be included in the claims in the present invention scope.
