In the bending forming section, there is a rotating unloading frame at the other end of the tempering and cooling section, and a transitional roller table is set between the unloading frame and the section; the precision of glass bending and forming is high, and the glass is avoided in the original processing method. There are straight-edge defects at both ends. At the same time, because the glass moves at a constant speed in one direction, the phenomenon that the glass is easily worn by the roller table and the occurrence of tempered stress spots in the original reciprocating swing method is greatly reduced.

Description

Horizontal roller type glass continuous bending and tempering forming device

The utility model relates to tempered glass processing equipment, in particular to a horizontal roller table type continuous bending and tempering forming device for glass.

At present, the more advanced method of single-curved tempered glass in the world is the roller table variable arc method, that is, the heated glass is conveyed to the forming section by the roller table, and the roller table and the lower air grille of the forming section are in a horizontal state (see Attached drawing 1), after all the glass enters the forming section, the roller table and the lower air grid of the forming section become concentric circular arcs under the drive of the driving device, and the soft glass plate, under the action of its own weight and the upper pressure roller, moves along with it. The lower roller table turns into a curved glass. At this time, driven by the lower roller table, the glass moves back and forth continuously while being blown by the upper and lower air grids to be tempered and cooled (see Figure 2), and then the lower air grid and the transmission roller table After flattening, the upper air grid and the upper pressure roller are raised, and the transmission roller sends the tempered glass to the section to be taken off manually. This method has two outstanding defects. One is that the distance between the transmission rollers is subject to the installation position of the bellows and the consideration of not affecting the wind-blown glass, so it is generally ≥100mm, and the upper pressure roller is between the two transmission rollers. Above the middle of the roller, so that when the glass is forced to bend, there will be a straight edge not less than 50mm long at both ends of the glass. Roller wear or uneven roller marks are prone to appear.

The purpose of this utility model is to provide a horizontal roller type glass continuous bending and tempering device with one-way constant speed operation. Uneven quality defects.

The technical scheme of the utility model is: the utility model comprises a heating section, a tempering cooling section, a segment taking section and a roller drive device connected in sequence, and a glass bending forming section is set between the heating section and the tempering cooling section. The forming section is composed of at least 3 pairs of pressure rollers facing up and down. It and the tempering and cooling section are in the shape of a curved and adjustable arc in the direction of the roller table. There is a rotating unloading frame at the other end of the tempering and cooling section. A transitional roller table is also set between the sheet rack and the segment; blowing devices are set above and below the roller table of the tempering cooling section.

The rotary film unloading frame includes multiple pairs of variable arc pressure roller frames and a rotating shaft connected to one side thereof, and the rotating shaft is connected to a fixed fulcrum in rotation.

The blowing device includes an upper wind bag, a lower wind bag, a sub-air box and a flexible air pipe. The upper and lower air bags are connected to one end of the sub-air box through the flexible air tube. The air outlet of the sub-air box is located between each roller table in the tempered cooling section.

There are three pairs of upper and lower pressure rollers in the forming section, and the distance between each pair is 30-60m.

The utility model has the advantages of high precision of glass bending and forming, and avoids the defect of straight edges at both ends of the glass in the original processing method. At the same time, because the glass moves at a unidirectional constant speed, the original reciprocating swing In the method, the glass is easily scratched by the roller table and tempered stress spots appear.

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is a schematic structural view of the horizontal state of the forming section in the prior art bending tempering device;

Fig. 2 is a structural schematic diagram of the bending state of the forming section in the prior art bending tempering device;

Fig. 3 is a schematic structural view of the present invention.

Referring to Fig. 1 and Fig. 2, the prior art method for single-curved tempered glass is the roller table variable arc method, that is, the heated glass 1 is transported to the forming section by the roller table 2, and at this time, the roller table 2 of the forming section and the downwind The grids 4 are all in a horizontal state (see attached drawing 1). After all the glass 1 enters the forming section, the roller table 2 and the lower air grid 4 of the forming section become concentric circular arcs driven by the driving device, and the soft glass plate 1 Under the action of its own weight and the upper pressure roller 5, the lower roller table 2 becomes a curved glass. At this time, driven by the lower roller table 2, the glass moves back and forth continuously while being blown by the upper and lower air grids 4 simultaneously to be tempered. and cooling (seeing accompanying drawing 2), then the lower wind grid 4 and the drive roller table 2 flatten, the upper wind grid 3 and the upper pressure roller 5 rise, and the drive roller table 2 delivers the toughened glass to the section to be taken off manually.

Referring to Fig. 3, its roller table includes sequentially connected heating section 6, tempering and cooling section 8, taking section 11 and roller table driving device, and a glass bending forming section 7 is set between the heating section 6 and tempering and cooling section 8 , the forming section is composed of at least three pairs of pressure rollers 71 facing up and down, and it and the tempering cooling section 8 are in the shape of an adjustable arc curved upwards in the direction of the roller table. A sheet rack 9, a transitional roller table 10 is also arranged between the unloading sheet rack 9 and the section 11; blowing devices are arranged above and below the roller table of the tempering cooling section 8.

The rotary unloading frame 9 includes multiple pairs of variable arc pressure roller frames 91 and a rotating shaft 92 connected to one side thereof, and the rotating shaft is connected to a fixed fulcrum 12 in rotation.

Described blowing device comprises upper wind bag 13, lower wind bag 14, sub-air box 15 and flexible air pipe 16, and upper and lower air bag 13,14 is connected with sub-air box 15 one ends by flexible air tube 16, and the air outlet of sub-air box 15 is positioned at tempered The cooling section 8 is between each roller table.

There are three pairs of upper and lower pressure rollers 71 in the forming section 7, and the distance between each pair is 30-60m.

The heated glass 1 is sent out of the furnace by the ceramic roller table 2 in the furnace, and first enters the forming section 7. There are three pairs of pressing rollers 71 in this forming section, and multiple pairs of pressing rollers 71 can also be set according to the needs. The radius is pre-adjusted and the curvature R is adjusted. Since the distance between each pair of pressure rollers is small (30-60mm), the shape precision of the glass that is forced to bend and deform is very high, and there is no defect of straight edges at both ends of the glass in the original method. , after the glass 1 is bent and deformed, it directly enters the arc-shaped tempered cooling section 8, while being tempered and cooled by blowing air, while being conveyed to the upper right by the counter-roller at a constant speed, the tempered and cooled tempered glass is sent to the rotary unloading rack After 9, the unloading frame 9 rotates to the right, and the glass is sent to the transition roller table 10, and finally enters the section 11, and the glass 1 is taken off manually. In addition, if the upper and lower roller tables in this method are respectively made into a convex-drum type and a concave-drum type, it can also be used to process hyperboloid curved tempered glass.
