Specific embodiment
The utility model is further described with reference to the accompanying drawing.Following embodiment is only used for clearly illustrating this
The technical solution of utility model, and cannot be used as a limitation the limitation protection scope of the utility model.
The orientation or positional relationship of the instructions such as term " upward ", " downward " "upper" "lower" in the description of the present invention,
To be based on the orientation or positional relationship shown in the drawings, being merely for convenience of description the utility model rather than requiring the utility model
Must be with specific orientation composition and operation, therefore should not be understood as limiting the present invention.
The present embodiment provides a kind of film machine roller regulating devices, including upper roller, lower roller and rack:
The shaft of lower roller 9 is supported in first bearing seat 12 by first bearing 11, the first bearing 11 and first
Bearing block 12 is rotatablely connected, and first bearing seat 12 is fixedly connected on the rack；By the connection method, lower roller 9 passes through the
One bearing 11 and first bearing seat 12 are fixed on the rack, it can be achieved that rolling along central axis, and can not move along other directions
It is dynamic；
The shaft of upper roller 8 is supported in second bearing seat 7 by second bearing 10, the second bearing 10 and the second axis
The rotation connection of seat 7 is held, second bearing seat 7 is fixedly connected on 6 lower part of connection frame；
The top of connection frame 6 is fixedly connected with 3rd bearing seat 5, and the 3rd bearing 4 and the rotation of 3rd bearing seat 5 connect
It connects, it is preferred that 3rd bearing 4 is angular contact bearing, and 3rd bearing 5 is able to bear axial force；
The lower end of screw rod 13 relatively rotates connection by 3rd bearing 4 and 3rd bearing seat 5, it is preferred that screw rod 13 is ladder
Shape screw rod, the threaded portion of screw rod 13 are equipped with copper nut 14, and copper nut 14 is fixed on bracket 2 by flange, bracket 2 and rack
