Description
Technical Field
The invention relates to the field of liquid crystal glass production, in particular to a TFT-LCD (thin film transistor-liquid crystal display) forming traction roller.
Background
The drawing roll is important process equipment of TFT-LCD liquid crystal glass, the thickness of the TFT-LCD liquid crystal glass in the specification is achieved in the forming and shaping process, and the drawing speed of the drawing roll is mainly controlled. Therefore, the requirement on the running precision of the drawing linear speed of the drawing roller is very high, which indirectly puts higher requirements on the material and the manufacturing precision of the drawing roller.
Due to the used materials and manufacturing process of the traction roller in actual production, the traction roller is deformed in different degrees after working for a period of time under a high-temperature working condition, so that the actual linear speed of the traction roller in operation has larger difference in a circular motion period. Particularly, when the traction roller runs to the end of the service life, due to the influence of abrasion and continuous deformation of the traction roller, the difference of the actual linear speed of the traction roller in a circular motion period is very obvious, great influence is caused on the stability of a forming process, and the fluctuation of quality parameters is great; because the deformation positions of the traction rollers of each pair of traction rollers are different, in an extreme case, namely when the highest point of one traction roller is contacted with the lowest point of the other traction roller, the two traction rollers suddenly change the contact position in the radial direction, impact force can be generated on a drawn glass plate, cracks can be generated on the glass plate in serious cases, and even the risk that normal production is interrupted due to plate breakage occurs. In order to safely maintain normal production, the pulling rolls need to be replaced frequently and regularly, which reduces the overall efficiency of the production line.
In summary, the prior art pulling roll structure has the following disadvantages: the traction roller is continuously extruded to generate deformation in the using process, and the deformed traction roller can cause the linear velocity of the traction roller to be inconsistent, so that the thickness difference quality parameters of the product are influenced; this drawback also causes a short service life of the traction rollers, requiring frequent periodic replacement of the traction rollers, reducing the overall efficiency of the production line.

Optionally, the outer diameter of the attachment 19 is 10-20mm larger than the outer diameter of the reinforcing blades 18, so that the outer circumference of the roller unit ring 3 is an outer ring 25 formed of a high temperature resistant material; the thickness of the attachment 19 is 0.5-2mm larger than that of the two ends of the internal strengthening structure 15, so that the two end surface layers of the roller body unit rings 3 are made of high-temperature-resistant materials, and the contact between the adjacent roller body unit rings 3 is also made of the high-temperature-resistant materials.
In the present embodiment, with reference to fig. 4, 5 and 6, the reinforcing blades 18 comprise planar blades 20, the plane of the planar blades 20 being perpendicular to the axis 22 of the inner ring 17; the radial inner end of the plane blade 20 is fixedly connected to the outer peripheral surface of the inner ring 17, two side edges of the plane blade 20 are respectively bent to form folded edges 21, and the folded edges 21 are perpendicular to the plane where the plane blade 20 is located, so that the section of the reinforced blade 18 in the plane perpendicular to the radial direction of the inner ring 17 is in a U shape; one end of the folded edge 21 close to the inner ring 17 is fixedly connected to the inner ring 17.
In this embodiment, the roll shaft 1 may be made of a high temperature resistant alloy, and the temperature resistance thereof may be as high as 900 ℃.
