Description

Technical Field

[0001] The utility model relates to the technical field of glass processing, in particular to a preheating structure and a curved glass processing device. Background Art

[0002] The process of curved glass processing includes at least preheating, hot pressing and cooling. In the preheating process, multiple preheating structures are usually used to preheat and heat the curved glass forming mold in layers. For example, the Chinese utility model patent application with application number 201720203636.5 discloses a first preheating device, a second preheating device, a third preheating device and a fourth preheating device arranged in the form of an assembly line are used to heat the curved glass forming mold in stages by heat conduction. Specifically, each preheating device includes a cylinder, an upper cooling plate, an upper heating device, a lower cooling plate and a lower heating device. The upper cooling plate and the lower cooling plate are respectively connected to the power output end of the cylinder, thereby blocking the heat generated by the upper heating device and the lower heating device from being conducted to the cylinder. The influence on the operation of the cylinder and other structures is reduced, and the dry-burning deformation of the heating plates in the upper heating device and the lower heating device is reduced. However, the setting of the upper cooling plate and the lower cooling plate will cause the heat loss of the upper heating device and the lower heating device. Although a spacer is provided between the upper cooling plate and the upper heating device, and between the lower cooling plate and the lower heating device to slow down the loss of heat generated by the upper heating device and the lower heating device and reduce the dry-burning deformation of the heating plates of the upper heating device and the lower heating device, in fact, the heat generated at the upper heating device and the lower heating device is still lost to a large extent under the action of the upper cooling plate and the lower cooling plate, which results in a large energy consumption in the processing of curved glass and increases the cost of the processing of curved glass.

Furthermore, the driving member 200 is a driving cylinder, which is used to drive the first fixing seat 500 to move in a direction away from or close to the second fixing seat 700, thereby achieving effective preheating of the mold 20.

[0031] The above-mentioned preheating structure 10 enables the first heating plate 300 to be connected to the side of the first fixed seat 500 close to the first insulation cotton seat 600, and the first insulation cotton seat 600 is at least partially sandwiched between the first fixed seat 500 and the first heating plate 300, and cooperates to enable the second heating plate 400 to be connected to the side of the second fixed seat 700 close to the second insulation cotton seat 800, and the second insulation cotton seat 800 is at least partially sandwiched between the second fixed seat 700 and the second heating plate 400, that is, the first insulation cotton seat 600 and the second insulation cotton seat 800 enhance the structural strength of the corresponding first heating plate 300 and the second heating plate 400.

[0039] In one of the embodiments, the number of the telescopic buffer members 1100 is two or more, each telescopic buffer member 1100 is arranged to avoid the driving member 200, and two or more telescopic buffer members 1100 are evenly arranged around the outer circumference of the driving member 200, so that the telescopic buffer member 1100 can disperse and evenly buffer the impact force generated on the mold 20 when the first heating plate is pressed down, further improving the effective buffering and reduction of the impact force of the telescopic buffer member 1100 on the first heating plate 300, thereby better ensuring the reduction of wear on the mold 20, reducing the replacement of the mold 20, and further reducing the cost of curved glass processing.

[0040] In one embodiment, the telescopic buffer 1100 includes an elastic telescopic portion 1110 and a connecting portion 1120, one end of the elastic telescopic portion 1110 is connected to a side of the mounting frame 100 away from the first fixed seat 500, the other end of the elastic telescopic portion 1110 is protruding from the mounting frame 100, the connecting portion 1120 is penetrated through the mounting frame 100 and is slidably connected to the mounting frame 100, one end of the connecting portion 1120 is penetrated through the elastic telescopic portion 1110 and is connected to an end of the elastic telescopic portion 1110 away from the mounting frame 100, and the connecting portion 1120 is slidably connected to the elastic telescopic portion 1110, and the other end of the connecting portion 1120 is connected to the first fixed seat 500, thereby effectively achieving the buffering and reduction of the impact force exerted by the telescopic buffer 1100 on the first heating plate 300.

[0041] In one embodiment, the elastic telescopic part 1110 is provided with a sliding through hole 1101, and the connecting part 1120 is respectively provided in the mounting frame 100 and the sliding through hole 1101, and the end of the connecting part 1120 away from the first fixing seat 500 moves toward or away from the elastic telescopic part 1110. Further, when the end of the connecting part 1120 away from the first fixing seat 500 moves toward the direction close to the elastic telescopic part 1110, the connecting part 1120 moves to abut against the side of the elastic telescopic part 1110 away from the mounting frame 100, and the connecting part 1120 compresses the elastic telescopic part 1110; when the end of the connecting part 1120 away from the first fixing seat 500 moves toward the direction away from the elastic telescopic part 1110, the connecting part 1120 releases the elastic telescopic part 1110, and the connecting part 1120 is separated from the elastic telescopic part 1110, which further achieves a better buffering reduction of the impact force exerted by the telescopic buffer 1100 on the first heating plate 300.
