Abstract

The utility model provides a flat glass calendering roll. A plurality of water cavities extending along the axis of a roll body are uniformly arranged inside the roll body; and the roll body is provided with water inlets and water outlets which are communicated with corresponding water cavities. According to the flat glass calendering roll, the plurality of water cavities are arranged inside the roll body; parts on the roll body, corresponding to the water cavities, are controlled to expand or retract by controlling the water inlet quantities of different water cavities, and then the thickness of flat glass is adjusted; and the service life of the calendering roll is effectively prolonged.

Description

A kind of sheet glass stack

Technical field

The utility model relates to a kind of sheet glass stack.

Background technology

Sheet glass calendering technical matters requires very strict, and very little between the thickness difference wave zone, this just requires the last bottom calender roll of glass ware forming must keep good parallelism.When expecting that temperature is normal always and not having foreign matter; Each item technology indexes such as cooling water inlet water temperature, hydraulic pressure just often are prone to realize roller normal work-ing life; But in actual production, tend to various abnormal conditions occur, and the detrimentally affect that brings of the original parallelism of hot environment pair of rollers.Normal use that so will pair of rollers brings hidden danger, causes roller short work-ing life, thereby the raising of restriction economic benefit is produced in influence.

The utility model content

The purpose of the utility model provides a kind of sheet glass stack, the work-ing life of effectively improving stack.

To achieve these goals, the utility model adopts following technical scheme:

A kind of sheet glass stack comprises the top roll and the lower roll of pressed glass, evenly is provided with a plurality of water cavities that extend along the roll body axis direction in the roll body of top roll and lower roll; Said roll body is provided with water-in and the water outlet that is communicated with corresponding water cavity.

Evenly be provided with 4 water cavities in the said roll body.

Said sheet glass stack comprises the two ends spindle nose, and said roll body spindle nose is installed on the chock.

Said sheet glass stack comprises that further thickness of glass proofing unit that detects thickness of glass and the gear that links to each other with this thickness of glass proofing unit are to regulate the water yield of roller water cavity.

Compared with prior art; The utlity model has following advantage: a kind of sheet glass stack of the utility model, through a plurality of water cavities evenly are set, control the flooding quantity of different water cavities in roll body; Thereby the expansion or the contraction of control water cavity corresponding position roll body, and then the thickness of control sheet glass; Effectively prolonged the work-ing life of stack.

Description of drawings

Fig. 1 is the structural representation of the utility model sheet glass stack;

Fig. 2 is the sectional view of Fig. 1 along the A-A line.

Embodiment

Below in conjunction with accompanying drawing the utility model is done and to be described in further detail.

Consult Fig. 1 and shown in Figure 2, the utility model sheet glass stack comprises top roll 1 and lower roll 2, evenly is provided with a plurality of water cavities 20 that extend along the roll body axis direction in each roll body of top roll 1 and lower roll 2; Said roll body is provided with water-in and the water outlet that is communicated with corresponding water cavity 20.

Said water cavity has four, and said sheet glass stack further comprises the two ends spindle nose, and said roll body spindle nose is installed on the chock.

Said sheet glass stack further comprises thickness of glass proofing unit and coupled gear.

Being installed on the chock of said top roll 1, lower roll 2 evenly is provided with four water cavities 20 in the roll body.After some stacks deform; The thickness of glass proofing unit will detect through thickness of glass; And on the glass ribbon that the stack of distortion extrudes, make the mark of position, the every chamber of corresponding roller; The data of measuring mark position thickness of glass also are transferred to gear with these data through the thickness of glass proofing unit, and corresponding roller chamber, roller surfaces highs and lows place is found out in the gear analysis, and the cooperation of finally regulating roller highs and lows position realizes.Concrete control method is: as if top roll 1, lower roll 2 arbitrary distortion, then regulate the flooding quantity of distortion place water cavity 20.Because roller (1,2) is a metal products, has the principle of expanding with heat and contract with cold, therefore, if thicker these water cavity 20 flooding quantitys of roller that then turn down accordingly of certain glass ribbon mark glass make these water cavity 20 correspondences go out the roll temperature rising and expand; Then increase this water cavity 20 flooding quantitys than thin, make these water cavity 20 correspondences go out roll temperature decline and shrink; Regulate in principle to highlight most and locally be more or less the same everywhere and carry out to reach with roller other.

If top roll 1, lower roll 2 bending simultaneously; Then according to mark up-down rollers water chamber 20 positions; Through adjustment roller matching speed find the maximum of top roll 1 and lower roll 2 smallest point match (or the maximum point of the smallest point of top roll 1 and lower roll 2 matches) take run-in synchronism; Reach prolongation roller (1, the 2) purpose in work-ing life through a kind of like this method, the increase economic benefit economizes on resources.
