Description
Technical field
The present invention relates to calendering milling trains, more specifically refer to that milling train is prolonged in a kind of two roll-in of high-precision anti-jumping.
Background technique
The calender roll that milling train is mainly used for plastic film is prolonged in two roll-ins, since rolling thickness is very thin, to it
Required precision is very high, and wherein controls the distance between two rolls mostly important.But in actual use, due to
Roll is without limit and adjustment mechanism accordingly, therefore after previous coiled strip rolls, and when rear a roll does not roll, two rolls receive rolling
Power influence can generate relative displacement, and distance between two rolls is caused to reduce, and become so as to cause head thickness when the rolling of latter coiled strip
It is small.Also, when the soft or hard degree of rolling material not for the moment, not can guarantee the uniform of rolling thickness yet.In addition, due to roll and bearing
There is gap between seat, in rolling, bounce can be generated, once beating, also results in rolling unevenly, cause the wave of material
Take.
Summary of the invention
The purpose of the present invention is in view of the foregoing drawbacks, proposing that milling train is prolonged in a kind of two roll-in of high-precision anti-jumping, it is not only able to
Prevent roll from beating, but also being capable of distance between precise control amount roll.
To achieve the goals above, the present invention uses following technical scheme.
Milling train is prolonged in a kind of two roll-in of high-precision anti-jumping, and a pair roller including base, on base further includes anti-jump
Motivation structure and pitch control mechanism, anti-bounding device have two sets, are respectively arranged on the both ends of roll, every set anti-bounding device is equal
Including a chest expander and a pair of of connecting plate, the upper end of two connecting plates is hinged with the tie rod end of chest expander, two connecting plates
Lower end is connected respectively at the same side spindle nose of two rolls；Pitch control mechanism also has two sets, respectively with the both ends of roll
Bearing block offset.
Every set pitch control mechanism includes a pair of of screw rod, and two screw rod one end are on the outside of the bearing block of ipsilateral two roll
Face offsets.
The pitch control mechanism further includes the rack screw rod is arranged being respectively arranged on the outside of roll.
Described screw rod one end is equipped with bulb, is offseted by bulb and bearing block lateral surface.
The calendering milling train further includes an automatic control system, automatic control system include controller, tension sensor,
Screw drive motor, pulling force of the tension sensor to detect pull rod, controller receives pulling force signal, and exports control signal,
Corresponding screw rod is driven to carry out precession or back-out to control screw drive motor.
In above-mentioned technical proposal of the invention, two roll-in of high-precision anti-jumping of the invention prolongs milling train and passes through anti-jump motivation
The chest expander of structure pulls down or two roll spindle noses of pull-up, thus to control the distance between two rolls, and roll can be prevented
Bounce is adjusted by the screw rod of pitch control mechanism, further the distance of two rolls of accurate adjustment, and plays lateral limit to roll
Position effect, prevents from springing back.Also, screw rod is offseted by bulb and bearing block lateral surface, will not answer bearing block deviate and generate by
Power offset.
Detailed description of the invention
Fig. 1 is the structural side view that milling train is prolonged in two roll-in of high-precision anti-jumping of the invention；
Fig. 2 is pitch control mechanism installation top view of the invention；
Fig. 3 is the functional block diagram of automatic control system of the invention.
Specific embodiment
Technical solution of the present invention is further illustrated with reference to the accompanying drawing.
It please refers to shown in FIG. 1 to FIG. 2, it is same as the prior art that milling train is prolonged in a kind of two roll-in of high-precision anti-jumping of the invention
, equally also include base 1, a pair roller 2 on base 1 further include unlike the prior art anti-jump motivation
Structure 3 and pitch control mechanism 4, anti-bounding device 3 have two sets, are respectively arranged on the both ends of roll 2, every set anti-bounding device 3
It include a chest expander 31 and a pair of of connecting plate 32, the upper end of two connecting plates 32 is mutually cut with scissors with 33 end of pull rod of chest expander 31
It connects, the lower end of two connecting plates 32 is connected respectively at the same side spindle nose 21 of two rolls 2, downward by the pull rod 33 of chest expander 31
It draws, can be pulled up to 2 one, roll oblique outer power by the pull rod 33 of chest expander 31, it can be to 2 one, roll in the diagonal
Power guarantees the thickness of rolling to can control the distance between two rolls 2 in rolling, and can prevent the bounce of roll 2,
Improve the quality of rolled products.
And pitch control mechanism 4 also has two sets, every set pitch control mechanism 4 includes a pair of of screw rod 41, two screw rods 41
One end offsets respectively at 22 lateral surface of bearing block of ipsilateral two roll 2.It, can also be further to rolling by 41 precession of screw rod or back-out
Distance between roller 2 is accurately adjusted, and plays the role of cross spacing, prevents roll 2 from springing back.
As one embodiment, the pitch control mechanism 4 further includes being respectively arranged on the outer side frame 42 of roll 2, to
Screw rod 41 is set.
As one embodiment, described 41 one end of screw rod is equipped with bulb 43, passes through bulb 43 and 22 lateral surface of bearing block
It offsets, can not be influenced by the bounce of roll 2, deviation etc. using bulb 43, vertical roller 2 always of bearing block 22 1 can be given
Top power on axis direction.
As one embodiment, the calendering milling train further includes an automatic control system, sees Fig. 3, the automatic control system
System includes controller, tension sensor, 41 driving motor of screw rod, pulling force of the tension sensor to detect pull rod 33, controller
Receive pulling force signal, and export control signal, drives corresponding screw rod 41 to carry out precession or back-out to control 41 driving motor of screw rod,
And the pulling force of adjustment chest expander 31, to realize adaptive adjustment control.
In conclusion prolonging milling train using two roll-in of high-precision anti-jumping of the invention, pass through the chest expander of anti-bounding device 3
31 drop-downs or pull-up two rolls, 2 spindle nose 21, thus to control the distance between two rolls 2, and the jump of roll 2 can be prevented
It is dynamic, it is adjusted by the screw rod 41 of pitch control mechanism 4, further the distance of two rolls 2 of accurate adjustment, and cross is played to roll 2
To position-limiting action, prevent from springing back.Also, screw rod 41 is offseted by bulb 43 and 22 lateral surface of bearing block, will not answer bearing block 22
It deviates and generates stress offset.Prolong milling train using two roll-ins of the invention, can be improved production precision, suitable for micron order thickness
Rolling plastic film, and guarantee the uniform of product thickness end to end, thickness error is can be controlled within 3 microns, reduces material
Waste.
Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate the present invention,
And be not used as limitation of the invention, as long as the change in spirit of the invention, to embodiment described above
Change, modification will all be fallen within the scope of claims of the present invention.
