Abstract
A kind of composite diaphragm production brush roll, for producing in composite diaphragm, including roll shaft and tuft, tuft is arranged on the outer surface of roll shaft, described tuft includes center tufts and side tuft, center tufts is arranged on the axial centre of roll shaft, become rectangular arrangement, the both sides of the centrally disposed tuft of side tuft, become the arrangement of oblique line battle array, the angle of every side tuft line and axis is α, α is 10～20 °, after this utility model acts on film roll, before jockey pulley, during work, tuft is bent and it produces the power of both direction to the left and right, serve buffering tension force and flatten the effect of fold, this utility model simple in construction in a word, it is applicable to industrialized production.
Description
Technical field
This utility model provides the brush roll in a kind of brush roll, particularly composite diaphragm production process, belongs to thin film technique
Field.
Background technology
In the production process of composite diaphragm, barrier film is generally through needing overtension roller, deflector roll, flattening guide roller, traction nip rolls, again
Enter compound nip rolls, owing to film roll can rotate during unreeling, cause the barrier film linear velocity when being drawn off to have the biggest
Fluctuation, to such an extent as to fold can produced through deflector roll, and after thin film is stretched to certain thickness, the both sides of thin film
Limit is also easy to wrinkling, if do not flattened thin film in time, rolling rear film is scrapped as undesirable product.
Therefore, in the production process of thin film, flatten fold in time critically important.
Utility model content
This utility model is used for overcoming the defect of prior art, providing a kind of composite diaphragm production brush roll, and it can
Buffer thin film tension force, flattening fold, improve thin film apparent mass.
Described in the utility model technical problem is that solves by the following technical programs:
A kind of composite diaphragm production brush roll, including roll shaft and tuft, tuft is arranged on the outer surface of roll shaft, described hair
Bunch include center tufts and side tuft.
Above-mentioned composite diaphragm production brush roll, described center tufts is arranged on the axial centre of roll shaft, becomes rectangular row
Row, account for the 1/20～1/10 of roll shaft total length.
Above-mentioned composite diaphragm production brush roll, the both sides of the described centrally disposed tuft of side tuft, become oblique line battle array row
Row, the angle of every side tuft line and axis be α, α be 10～20 °.
Above-mentioned composite diaphragm production brush roll, the angle of described center tufts and roll shaft normal be β, β be 20～30 °,
Every two beam center tufts are symmetrical along normal.
Above-mentioned composite diaphragm production brush roll, the angle of described side tuft and roll shaft normal be γ, γ be 20～
30 °, side tuft direction is with membrane direction in the same direction.
This utility model has the advantage that
This utility model is provided with the center tufts being positioned at roll shaft center, and is positioned at the side tuft at roll shaft two ends, center
Tuft is symmetrical arranged two-by-two, and side tuft incline direction is consistent with membrane direction, and so, when linear velocity is slow, tension force becomes big, hair
Bunch it is bent and it produces the power of both direction to the left and right, serve buffering tension force and flatten the effect of fold.Center tufts one row
Arrange parallel uniform, and center tufts is interspersed to from left to right；Difference from side tuft is that the distribution of angle is different.In
Between tuft to both sides tilt, it is ensured that thin film does not produce fold.
Accompanying drawing explanation
Fig. 1 is the signal of this utility model planar structure；
Fig. 2 is that this utility model A-A is to schematic diagram；
Fig. 3 is that this utility model B-B is to schematic diagram.
In figure, each label is expressed as: 1, roll shaft, and 2, center tufts, 3, side tuft.
Detailed description of the invention
Refering to accompanying drawing 1, this utility model includes roll shaft 1 and tuft, and tuft is arranged on the outer surface of roll shaft 1, and tuft includes
Center tufts 2 and side tuft 3, center tufts 2 is arranged on the axial centre of roll shaft 1, becomes rectangular arrangement, accounts for roll shaft 1 overall length
The 1/20～1/10 of degree.The both sides of the centrally disposed tuft of side tuft 32, become the arrangement of oblique line battle array, every side tuft 3 line with
The angle of axis be α, α be 10～20 °, two groups of side tufts 3 become herringbone.
Refering to accompanying drawing 2, this utility model crosses the installing hole of center tufts 2, does normal, center hair on the circumference of roll shaft 1
Angle bunch between 2 and normal be β, β be 20～30 °, every two beam center tufts 2 are along the prolongation in roll shaft 1 center of circle Yu tuft line
Line is symmetrical.
Refering to accompanying drawing 3, the angle of described side tuft 3 and roll shaft 1 normal be γ, γ be 20～30 °, side tuft 3 side
To with membrane direction in the same direction, so, film surface is not damaged by tuft force horizontal to barrier film.
After this brush roll is arranged on film roll, before jockey pulley, it is barrier film before entering jockey pulley, makes barrier film enter
During power roller, it is maintained for a flattened state.
