Description
Technical Field
The utility model relates to the technical field of manufacturing of ultrathin flexible glass, in particular to a pulling roller for pulling ultrathin flexible glass.
Background
At present, flexible glass refers to glass with a thickness of less than 0.1mm, and the glass with the thickness has certain flexibility and bending characteristics, and is widely applied to aspects of high-end display devices and electronic products. At present, the manufacturing process of the flexible glass mainly comprises a slit down-draw method, an overflow down-draw method, a glass melting re-draw method and a float method. The first three forming methods all require pulling rolls to apply a certain amount of tension to the ribbon to form thin glass of consistent thickness.
The pulling rolls are in direct contact with the glass surface during use and exert a pulling force on the glass by gripping and rotating the glass in opposite directions. In the downdraw apparatus, pulling rolls are typically located at the end exit of the lehr, at which time the glass has set. The conventional pulling roll generally uses a steel roll or a graphite roll with equal diameter, and the constant clamping force cannot be ensured because the pulling roll is made of hard materials when contacting with glass. In addition, the thickness difference and unevenness of the glass exist due to the unbalance of the surface tension and the pulling force in the downward drawing forming process, and the pulling roller is easy to pinch off the glass, so that the drawing process is interrupted, and the production efficiency is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a drawing roll for drawing ultrathin flexible glass, which can maintain constant clamping force and prevent drawing interruption caused by glass pinch breakage in a drawing process from influencing production efficiency.
The technical scheme adopted by the utility model is as follows:
the drawing roll for drawing ultrathin flexible glass comprises a drawing roll body, wherein two ends of the drawing roll body are respectively coated with an elastic contact part, the elastic contact parts are symmetrically arranged at two ends of the drawing roll body, and the height of the elastic contact parts is 8-20 mm.
The elastic contact part comprises five rubber strips, the five rubber strips are arranged in parallel, the width of each rubber strip is 8-20mm, the thickness h =10mm, and the rubber strips are distributed at equal intervals.
The distance between the rubber strips is 4-10 mm.
The surface where the rubber strip is located and the axial included angle of the drawing roller are not right angles.
The contact position of the elastic contact part and the two sides of the glass is separated from the two sides of the glass.
According to the utility model, the high-temperature resistant rubber strips are arranged at the two end parts of the drawing roller in a coating manner, so that the high-temperature resistant rubber strips on the drawing roller are contacted with the edge part of the glass when the glass is drawn, the constant drawing force is kept by the elasticity of the rubber and the glass, the effect of stable drawing is further achieved, and the glass can be prevented from being pinched off in the drawing process, so that the drawing continuity of the glass is improved, and the production efficiency is improved.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to the drawings without creative efforts.
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a partially enlarged view of the elastic contact portion according to the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
As shown in figures 1 and 2, the utility model comprises a drawing roller body, two ends of the drawing roller body are respectively coated with an elastic contact part, the elastic contact parts are symmetrically arranged at two ends of the drawing roller body, and the height of the elastic contact parts is 8-20 mm. The elastic contact part is composed of five rubber strips, the five rubber strips are arranged in parallel, the width of each rubber strip is 8-20mm, and the thickness h =10 mm. The distance between the rubber strips is 4-10 mm. The main shaft 1 of the drawing roller is coated with two elastic material areas consisting of high-temperature resistant rubber strips 2, and when glass is drawn, the glass is clamped and oppositely rotated by the elastic material areas of the two drawing rollers to form a stable drawing effect on the glass. Each elastic material zone contains 5 rubber strips, which are equally spaced apart by a distance d =4 mm.
The surface where the rubber strip is located and the axial included angle of the drawing roller are not right angles. Through the slope setting, can be in the increase of contact surface, further improvement traction force, and the traction force that avoids that the height change that can be fine brings changes.
The contact position of the elastic contact part and the two sides of the glass is separated from the two sides of the glass. The two elastic material zones of the pulling roll are in contact with the near inner side of the two side edge portions of the glass 3 to prevent the glass from being pinched off during the pulling process due to the uneven surface of the glass, which would cause interruption of the drawing process.
