Description

Milling train is prolonged in anti-jumping two roll-in of a kind of high accuracy

Technical field

This utility model relates to rolling milling train, more specifically refers to that milling train is prolonged in anti-jumping two roll-in of a kind of high accuracy.

Background technology

Two roll-ins are prolonged milling train and are mainly used for the calender roll of plastic sheeting, owing to rolling thickness is the thinnest, therefore to it Required precision is the highest, and wherein mostly important to the distance controlling between two rolls.But, in actual use, due to Roll not the most spacing and guiding mechanism, therefore after previous coiled strip rolls, latter volume a when not rolling, rolling received by two rolls Power impact can produce relative displacement, causes the spacing of two rolls to reduce, thus after causing, during a coiled strip rolling, head thickness becomes Little.Further, when rolling the soft or hard degree of material the most for the moment, the homogeneous of rolling thickness cannot also be ensured.Further, since roll and bearing There is gap between Zuo, when rolling, can produce and beat, once beat, also result in rolling uneven, cause the wave of material Take.

Utility model content

The purpose of this utility model is for drawbacks described above, proposes anti-jumping two roll-in of a kind of high accuracy and prolongs milling train, not only It is prevented from roll to beat, but also can distance between precise control amount roll.

To achieve these goals, this utility model is by the following technical solutions.

Milling train is prolonged in anti-jumping two roll-in of a kind of high accuracy, including support, a pair roller of being located on support, also includes anti-jump Motivation structure and pitch control mechanism, anti-bounding device has two sets, is respectively arranged on the both ends of roll, and often set anti-bounding device is equal Including a chest expander and a pair connecting plate, the upper end of two connecting plates all tie rod end with chest expander are hinged, 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.

Often set pitch control mechanism all includes a pair screw mandrel, and two screw mandrel one end are outside the bearing block of homonymy two roll Face offsets.

Described pitch control mechanism also includes the frame in order to arrange screw mandrel being respectively arranged on outside roll.

Described screw mandrel one end is provided with bulb, is offseted with bearing block lateral surface by bulb.

Described calendering milling train also includes an automatic control system, automatic control system include controller, pulling force sensor, Screw mandrel drives motor, and pulling force sensor is in order to detect the pulling force of pull bar, and controller accepts pulling force signal, and exports control signal, The corresponding screw mandrel of driven by motor is driven to carry out precession or back-out with control screw mandrel.

In technique scheme of the present utility model, high accuracy anti-jumping two of the present utility model roll-in is prolonged milling train and is passed through The chest expander of anti-bounding device is drop-down or pulls up two roll spindle noses, thus in order to control the distance between two rolls, and can prevent Stop beating of roll, adjusted by the screw mandrel of pitch control mechanism, the most accurately adjust the distance of two rolls, and roll is risen To cross spacing effect, prevent resilience.Further, screw mandrel is offseted with bearing block lateral surface by bulb, and bearing block will not be answered to offset And produce stress skew.

Detailed description of the invention

Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings.

Referring to shown in Fig. 1～Fig. 2, milling train and prior art are prolonged in a kind of high accuracy of the present utility model anti-jumping two roll-in A pair roller 2 that is identical, that the most also include support 1, be located on support 1, unlike the prior art, also includes anti-jump Motivation structure 3 and pitch control mechanism 4, anti-bounding device 3 has two sets, is respectively arranged on the both ends of roll 2, often overlaps anti-jump motivation Structure 3 all includes a chest expander 31 and a pair connecting plate 32, the upper end of two connecting plates 32 all with the pull bar 33 end phase of chest expander 31 Hinged, the lower end of two connecting plates 32 is connected respectively at the same side spindle nose 21 of two rolls 2, by the pull bar 33 of chest expander 31 to Drop-down, can give 2 one, roll oblique outer power, pulled up by the pull bar 33 of chest expander 31, can give 2 one, roll in the diagonal Power, thus when rolling, the distance between two rolls 2 can be controlled, it is ensured that the thickness of rolling, and beating of roll 2 can be prevented, Improve the quality of rolled products.

And pitch control mechanism 4 also has two sets, often set pitch control mechanism 4 all includes a pair screw mandrel 41, two screw mandrels 41 One end offsets respectively at bearing block 22 lateral surface of homonymy two roll 2.By screw mandrel 41 precession or back-out, it is possible to further to rolling Distance between roller 2 accurately adjusts, and plays cross spacing effect, prevents roll 2 resilience.

As an embodiment, described pitch control mechanism 4 also includes being respectively arranged on the outer side frame of roll 2 42, in order to Screw mandrel 41 is set.

As an embodiment, described screw mandrel 41 one end is provided with bulb 43, by bulb 43 and bearing block 22 lateral surface Offseting, use bulb 43 can not be beated by roll 2, deflection etc. affects, it is possible to give bearing block 22 1 vertical roller 2 all the time Top power on axis direction.

As an embodiment, described calendering milling train also includes an automatic control system, sees Fig. 3, and this automatically controls and is System includes that controller, pulling force sensor, screw mandrel 41 drive motor, and pulling force sensor is in order to detect the pulling force of pull bar 33, controller Accept pulling force signal, and export control signal, drive the corresponding screw mandrel of driven by motor 41 to carry out precession or back-out controlling screw mandrel 41, And the pulling force of adjustment chest expander 31, thus realize self-adaptative adjustment control.

In sum, high accuracy anti-jumping two of the present utility model roll-in is used to prolong milling train, by drawing of anti-bounding device 3 Power device 31 is drop-down or pulls up two roll 2 spindle noses 21, thus in order to control the distance between two rolls 2, and roll 2 can be prevented Beat, adjusted by the screw mandrel 41 of pitch control mechanism 4, the most accurately adjust the distance of two rolls 2, and roll 2 is played Cross spacing effect, prevents resilience.Further, screw mandrel 41 is offseted with bearing block 22 lateral surface by bulb 43, will not answer bearing block 22 offset and produce stress skew.Two roll-ins of the present utility model are used to prolong milling train, it is possible to increase to produce precision, be suitable to micron order The rolling plastic film of thickness, and ensure the uniform of product thickness end to end, within thickness error can be controlled in 3 microns, decrease The waste of material.

Those of ordinary skill in the art is it should be appreciated that above embodiment is intended merely to illustrate that this practicality is new Type, and it is not used as to restriction of the present utility model, as long as in spirit of the present utility model, to the above The change of embodiment, modification all will fall in Claims scope of the present utility model.
