Abstract

The utility model discloses a device for manufacturing a glass plate. The device comprises an overflow tank for producing a glass tape, wherein a stretching device is arranged at an outlet of the overflow tank and comprises paired stretching rollers with driving components; a clearance is formed between the two stretching rollers; the glass tape penetrates through the clearance; stretching roller supporting structural members are arranged at two ends of the stretching rollers; stretching roller clearance adjustment mechanisms are arranged on the stretching roller supporting structural members. The device for manufacturing the glass plate can be partially or fully used for pulling the glass tape and assisting in forming of the glass tape; air flow turbulence close to two sides of the glass tape is reduced as much as possible, so that the temperature field on the surface of the glass plate has least turbulence, and the temperature on the surface of the glass plate is stabilized.

Summary of the invention:

For above-mentioned defect or deficiency, the utility model provides a kind of device for the manufacture of sheet glass, can form protection to glass ribbon peripheral temperature field.

The technical solution of the utility model is:

Comprise the overflow groove for generation of glass ribbon, overflow groove exit is provided with stretching device, stretching device comprises paired setting and with the draw roll of drive element, between two draw rolls, form gap, glass ribbon is through described gap, the two ends of draw roll are provided with draw roll bracing member, are provided with draw roll clearance adjustment mechanism on draw roll bracing member.

Described stretching device comprises the draw rolls that form arranging more, and every group of draw roll is arranged side by side, and makes the alignment that all overlaps of the gap of every group of draw roll, and glass ribbon passes described gap.

Described drive element comprises pneumatic motor, oil motor, servomotor or pulse motor.

Described draw roll clearance adjustment mechanism is for being installed on draw roll bracing member.

On described stretching device, be provided with for detection of the proofing unit of glass ribbon two sidewinds and the gap detection control device of draw roll clearance adjustment mechanism.

Compared with prior art, the beneficial effects of the utility model are:

The device for the manufacture of sheet glass that the utility model provides, owing to being provided with stretching device below overflow groove outlet, and stretching device arranges in pairs and with the draw roll of drive element, draw roll can be used to intercept air-flow and traction glass ribbon; Draw roll can intercept upstream in the different steps of production process; glass ribbon peripheral temperature field is formed to protection; simultaneously; also can be partly or entirely for glass ribbon be carried out to tractive; the moulding of auxiliary glass band; reduce as much as possible the air turbulence near glass ribbon both sides, make the temperature field of glass pane surface there is minimum disturbance, stable glass sheet surface temperature.

Accompanying drawing explanation:

Fig. 1 is the structural representation of the device for the manufacture of sheet glass that provides of the utility model;

Fig. 2 is the structural representation for the manufacture of stretching device in the device of sheet glass that the utility model provides;

In figure, 1 is overflow groove, and 2 is stretching device, and 3 is glass ribbon, and 21 is draw roll, and 22 is draw roll bracing member, and 23 is drive element, and 24 is draw roll clearance adjustment mechanism.

Embodiment:

Below in conjunction with accompanying drawing, the utility model is described in detail.

Shown in Figure 1, the utility model provides a kind of device for the manufacture of sheet glass, comprises the overflow groove 1 for generation of glass ribbon 3, and the below of overflow groove 1 outlet is provided with stretching device 2.Concrete, shown in Figure 2, stretching device 2 comprises between paired setting and 21, two draw rolls 21 of draw roll with drive element 23 and forms gap, the two ends of draw roll 21 are provided with draw roll bracing member 22, are provided with draw roll clearance adjustment mechanism 24 on draw roll bracing member 22.Described draw roll clearance adjustment mechanism 24 can adopt counterweight, lever, cylinder, spring, air bag etc., and the spacing of draw roll is controlled in the target needing, and plays alleviation chimneyeffect, reduces the disturbance of convection of air to temperature field, exemplary, the screw body of take describes as example: draw roll clearance adjustment mechanism 24 is the adjustable cylinder of stroke, cylinder rod is mounted to one with draw roll bracing member 22, cylinder rod motion is with the screw mandrel of turning handle, screw mandrel is installed on draw roll bracing member 22, rotary screw rod handle, screw mandrel also rotates, take cylinder as example, draw roll is cylinder, cylinder rod is mounted to one with draw roll bracing member 22, cylinder rod motion is with the screw mandrel of turning handle, screw mandrel is installed on draw roll bracing member 22, rotary screw rod handle, screw mandrel also rotates, draw roll bracing member 22 can be moved, and then drive draw roll 21 to move, reach the object that regulates clearance distance between draw roll 21.Described drive element 23 comprises pneumatic motor, oil motor, servomotor or pulse motor, roller drive element 23 drives draw roll 21 always in rotating state, paired draw roll 21 sense of rotation are contrary, and it is consistent that linear velocity direction flows to direction at glass ribbon 3.Further, on described draw roll clearance adjustment mechanism 24, be provided with for forming the detecting unit of clearance distance between restrained stretching roller 21, and, for the gap between paired draw roll 21, can measure, according to take off data, when adjusting, technique can accomplish to quantize tracing and managing.

Preferably; the draw rolls 21 that form arranging can be set more; every group of draw roll 21 is arranged side by side; make the alignment that all overlaps of the gap of every group of draw roll 21; glass ribbon 3 is through described gap; multipair draw roll can partly or entirely form protection as intercepting upstream to glass ribbon peripheral temperature field in the different steps of production process, same time, also can be partly or entirely for glass ribbon is carried out to tractive, and the moulding of auxiliary glass band.

Working process of the present utility model:

First, each group regulates the distance between draw roll 21, make the gap between draw roll 21 reach stretching required separation distance, the outlet of overflow groove 1 is alignd with the gap of stretching between roller 21, then, in overflow groove 1, pack melten glass into, melten glass flows down and forms glass ribbon 3 from overflow groove, glass ribbon 3 enters the gap between the draw roll 21 in stretching device 2, pass through proofing unit, detect the air-flow of glass ribbon 3 both sides, when air turbulence, can adjust draw roll 21 gaps according to detecting data, make described gap remain on a scope that effectively intercepts flow perturbation, in addition, can regulate the gap between the draw roll 21 of other group, draw roll is contacted with glass ribbon 3, clamping glass band 3 produces drawing forces to glass ribbon 3 under the driving of draw roll drive element 23, makes glass ribbon 3 reach predetermined thickness.Draw roll drive element 23 drives draw roll 21 always in rotating state, and paired draw roll 21 sense of rotation are contrary, and it is consistent that linear velocity direction flows to direction at glass ribbon.

Can arrange that multipair draw roll can partly or entirely form protection as intercepting upstream to glass ribbon peripheral temperature field in the different steps of production process, same time, also can be partly or entirely for glass ribbon is carried out to tractive, the moulding of auxiliary glass band.

Above for the embodiment of the manufacturing installation of sheet glass; only, for better understanding the present invention, can make changes and improvements to above-described embodiment, and not depart from fact the present invention; all these changes and improvements are included in scope of the present invention, and are subject to the protection of claim.
