Abstract
The utility model provides a device for preventing rollers from cracking. The device comprises an asbestos coating layer for coating a roller core, and a stainless steel piece arranged in the asbestos coating layer to partition the same into a plurality of sections. The stainless steel piece arranged in the asbestos coating layer can protect a roller, frequent replacement of a number two traction roller is reduced, normal service life of the roller is prolonged, and production cost is lowered. In addition, cracking of the roller is effectively prevented, so that safe production is guaranteed and safety accidents are reduced.
Description
Technical field
The utility model belongs to the manufacturing technology field of TFT-LCD glass substrate, is specifically related to a kind of device that prevents that roller from cracking.
Background technology
No. two rollers removed edge machine in TFT base plate glass manufacturing processed be exactly unique roller that contacts with base plate glass, its effect has been draw, glass substrate is transmitted downwards, and can No. two roller working conditions directly determine to produce and carry out smoothly, changes 4 pairs of No. two rollers within one day sometimes at most.Because the glass temperature height, three kinds of media are at a temperature field (as 800 ℃), and thermal expansivity is different; So, the rod surface very easily cracks in hot work, will occur disconnected plate phenomenon so in the middle of producing, and influences the ordinary production of glass substrate, can cause structure deteriorate when serious, produces massive losses.
Roller of the prior art very easily cracks at coating layer under the situation of 800 ℃ of high temperature.Can not satisfy normal production; roller is changed frequent; the production cost height has a strong impact on production, and its reason is: metal material and the non-metallic material coefficient of expansion are inconsistent; material stroke under the situation of temperature variation is inconsistent; although early stage art breading done a few thing, increase the quantity of sheet asbestos, improve snap-in force; but at high temperature roller still the coating layer crackle occurs through regular meeting, and influence is produced normally.
Summary of the invention
The utility model proposes a kind of device that prevents that roller from cracking at the deficiencies in the prior art.
In order to address the above problem, the technical solution adopted in the utility model is: comprise for the asbestos coating layer that coats roller core and be arranged in the asbestos coating layer stainless steel substrates that the asbestos coating layer is separated into some sections.
Described stainless steel substrates spacing distance on the length direction of asbestos coating layer equates.
The steel disc that described stainless steel substrates is made for the SUS310S stainless steel identical with the roller core material.
The present invention is applicable to No. two traction rollers producing TFT base plate glass equipment, and when roller was worked under the situation of high temperature more than 800 ℃, the coefficient of expansion of asbestos coating layer and the coefficient of expansion of roller core were different, and stroke is inconsistent under the situation of temperature variation.Under the high temperature more than 800 ℃, the asbestos coating layer expands, and the stainless steel substrates of asbestos coating layer inside can stop the asbestos coating layer because of the dilatation that expansion produces, and has played the effect of the flexible and distortion that absorbs the asbestos coating layer.Therefore, in high temperature resistant nonmetal coating layer, stainless steel substrates is set and protects roller, reduced by No. two traction rollers and frequently changed, prolonged the normal work-ing life of roller, reduced production cost.And, owing to effectively prevented the fracture of roller, therefore, ensured safety in production, reduced the generation of security incident.
Description of drawings
Fig. 1 is device synoptic diagram of the present utility model;
Wherein, 1, roller core, 2, the asbestos coating layer, 3, stainless steel substrates.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described in detail.
Referring to Fig. 1, comprise for the asbestos coating layer 2 that coats roller core 1 and be arranged in the asbestos coating layer 2 stainless steel substrates 3 that asbestos coating layer 2 are separated into some sections, described stainless steel substrates 3 spacing distance on the length direction of asbestos coating layer 2 equates, described stainless steel substrates 3 is ring texture, and the external diameter of stainless steel substrates 3 is not more than the external diameter of asbestos coating layer 2, and the number of stainless steel substrates is 2-11.
Further, the steel disc made for the SUS310S stainless steel identical with rolling core matter of described stainless steel substrates 3.
The present invention is applicable to No. two traction rollers producing TFT base plate glass equipment, when roller is worked under the situation of high temperature more than 800 ℃, the coefficient of expansion that asbestos coating layer 2 coats and the coefficient of expansion of roller core 1 are different, and stroke is inconsistent under the situation of temperature variation; When under the high temperature more than 800 ℃, working, asbestos coating layer 2 expands, the stainless steel substrates 3 of asbestos coating layer 2 inside can stop the coating layer of anti-asbestos 2 because of the dilatation that expansion produces, and has played the effect of the flexible and distortion that absorbs asbestos coating layer 2.And the steel disc that employing SUS310S stainless steel is made can effectively adsorb the flexible and deformation that causes asbestos coating layer 3 because of high temperature deformation when the high temperature more than 800 ℃.Therefore, stainless steel substrates 3 is set in asbestos coating layer 2 can protects roller, reduced by No. two traction rollers and frequently changed, prolonged the normal work-ing life of roller, reduced production cost.And, owing to effectively prevented the fracture of roller, therefore, ensured safety in production, reduced the generation of security incident.
Repetition test through nearly half a year, 6 stainless steel substrates are set in asbestos coating layer 2 (minimumly in the test add two, add most 22) basically eliminate asbestos coating layer 2 situation of crackle appears, one month extend to half a year by original two weeks the work-ing life of roller, greatly the minimizing production loss, reduce production cost, stablized production.
