Technical field
The present invention relates in sheet glass production, if the problem in protective glass plate face, particularly relate to a kind of glass-board surface that solves and produce the method and apparatus of pressing against wound at transition roller.
Background technology
Along with the continuous maturation of glass production technology, scale constantly expands, and the demand of people to high-precision most advanced and sophisticated glass increases day by day, particularly constantly pursues the quality of high-grade float glass, so very strict to the requirement of glass upper and lower surface.In surface quality requirements, press against wound is exactly wherein affect one of chief reason, presses against wound and mainly results from transition roller and glass hits in glass ware forming, and processing this problem is like this emphasis place that glass quality improves.
Summary of the invention
The object of the invention is to the shortcoming and defect overcoming above-mentioned prior art, provide a kind of glass-board surface that solves and produce the method and apparatus of pressing against wound at transition roller, solve in float glass, particularly in glass ware forming, transition roller causes the problem of pressing against wound to glass.
Object of the present invention is achieved through the following technical solutions: a kind of glass-board surface that solves produces the device of pressing against wound at transition roller, the seal cavity comprised, seal cavity is in roller transmission mechanism between adjacent two rollers, its upper end open, the upper end level of seal cavity is lower than roller, seal cavity is parallel to two sides of roller bearing of trend respectively near the roller at seal cavity two ends, hollow tube is provided with in described seal cavity, the tube wall of hollow tube is densely covered with production well, and the port of hollow tube is communicated to the outer end of seal cavity.This device passes through gas by hollow tube to seal cavity; because only have the top exit of seal cavity; when the top of seal cavity is by sheet glass; there is it to block; such gas is after seal cavity is covered with, and will overflow from the contact surface of roller and sheet glass, sheet glass will lift by air-flow slightly that flow through; reactive force between sheet glass and roller is reduced, protects the bottom surface of sheet glass.
Further, the gap size of side respectively and between close roller that described seal cavity is parallel to roller bearing of trend is 2-5mm, gas is difficult to thus flows away in this gap, ensure that the gas flowed between sheet glass and roller can lift sheet glass, but also does not affect the rotation of roller.
Further, described seal cavity is by graphite grazing cover, under space sealing plate and roller, steel structure surrounds, described graphite grazing cover is the side being parallel to roller bearing of trend in seal cavity, steel structure under the touch roll of graphite grazing cover lower end, upper end and roller close, and shape is mated with roller, described space sealing plate is the side of vertical roller bearing of trend in seal cavity, it is arranged at the spindle nose both sides of roller, steel structure under the lower end touch roll of space sealing plate, space sealing plate does not contact with roller with graphite grazing cover, do not affect the work of roller, the bottom surface of steel structure composition seal cavity under employing roller, save material.
Further, the port of above-mentioned hollow tube is provided with a well heater, arrange well heater to heat entering gas, the present invention is arranged on the roller transmission mechanism of glass ware forming outlet, sheet glass herein also processes in high temperature, if blown a cold wind over, can cause damage to sheet glass, so this device being consistent to shaping temperature out by being blown into gas heating, then passing into seal cavity and using.
Further, the bearing of trend of above-mentioned hollow tube is consistent with roller, the through seal cavity of hollow tube, if gas outlet is only in the one end being positioned at sheet glass and roller contact surface, air-flow may lift one end of glass, the gravity of glass just concentrates on the other end, the other end just has larger reactive force with roller, larger injury is had to glass, the through seal cavity of outlet of gas of the present invention, and the scope that gas is given vent to anger enumerates the contact surface of whole sheet glass and roller, when air-flow lifts sheet glass, the contact surface of sheet glass and roller can be lifted by whole, solve and occur only having while the defect lifted, and because be blown into warm braw, namely heated roller, iff one end of warming mill, meeting formation temperature difference, causes very large injury to sheet glass.
Further; above-mentioned production well is uniformly distributed; its spacing is 2mm; after production well is uniformly distributed; the air strength size of blowout is consistent, and such sheet glass distributes consistent with the air strength at roller contact surface place, and the height that sheet glass lifts is just consistent; and roller by heating installation homogeneous heating, can protect sheet glass.
Further, above-mentioned production well diameter is 1/5th of hollow tube diameter, and the air-flow of blowout is uniformly dispersed under certain pressure space.
Hollow tube of the present invention adopts hot dip galvanizing pipe to make, and it is even that hot dip galvanizing pipe has coating, strong adhesion, the advantages such as long service life.
Solve glass-board surface and produce a method of pressing against wound at transition roller, comprise the following steps:
(1) in roller transport unit, all rollers are spaced, space is had between adjacent roller, now encapsulation process is carried out in all spaces or alternate space, form a surrounding and sealed bottom, the seal cavity of upper end open, seal cavity upper end port, lower than the extreme higher position of roller, does not affect roller transmission glass plate;
(2) in seal cavity, arrange the hollow tube of ventilation, the port of hollow tube is communicated to outer end;
(3) when roller transmitting sheet glass, namely begin through hollow tube and pass into gas to seal cavity, this gas is high temperature nitrogen, and the temperature of nitrogen is consistent with a upper operation temperature out, ensures the quality not affecting sheet glass;
(4) after seal cavity is covered with by nitrogen, because the sealing in other faces, namely nitrogen can overflow from roller and contact glass sheet face, and sheet glass slightly lifts by air-flow, reduces the contact of sheet glass and roller.
Further, above-mentioned passing in the gas of seal cavity also includes sulfurous gas, and the ratio of sulfurous gas shared by gas is that sulfurous gas is used for the physical property of cleaning roller and chilled glass lower surface, protects roller.
The invention has the beneficial effects as follows:
(1) adopt air-flow to lift sheet glass, the reactive force of sheet glass and roller is dropped to minimum, avoid sheet glass and pressed against wound by roller;
(2) because sheet glass just from production unit out, with high temperature, air-flow is heated to be current of warm air, avoids the injury of cold air stream to sheet glass;
(3) air-flow blowing sheet glass is uniformly distributed on the contact surface of sheet glass and roller, avoid sheet glass one end and lift, cause the drawback that the other end damages, and roller heating is uneven, to the drawback that sheet glass damages.
