[0024] Combine Figure 4 The pliers 24 includes a base. The left end of the base is provided with a groove 19 for placing wine glasses. Both sides of the inner wall of the groove 19 are fixed with a second spring 20, and the second spring 20 is fixed with an arc Shaped splint 21.
[0025] The specific implementation process is as follows:
[0026] Start the driver 16 first, the driver 16 drives the roller 15 to rotate, and the roller 15 drives the conveyor belt 14 to move. Then the two clamping plates 21 are pushed apart, and the wine glass to be processed is placed between the two clamping plates 21. After the clamping plates 21 are released, the two clamping plates 21 clamp the wine glass under the action of the second spring 20. Then start the motor 12, the output end of the motor 12 drives the output end of the reducer to rotate, and the output end of the reducer drives the first friction wheel 13 to rotate. The friction force between the first friction wheel 13 and the second friction wheel 11 is large, so The first friction wheel 13 drives the second friction wheel 11 to rotate, the second friction wheel 11 drives the clamping rod 9 to rotate, and the clamping rod 9 drives the wine glass to rotate; then start the flame spray gun 5, and the flame spray gun 5 generates an open flame and heats the wine glass. . When the flame spray gun 5 produces an open flame, the temperature of the open flame is extremely high. It not only heats the wine glass but also heats the air near the open flame. After the air is heated, the density decreases and gradually rises. At this time, the hot air interacts with the first resistor 6, the second resistor and The third resistance contact. When the temperature of the second resistance reaches 70℃ and above, the second solenoid valve 8 is energized and closed. When the temperature of the first resistance 6 and the third resistance reaches 100℃ and above, the first solenoid valve Power is turned on and turned off, and at the same time the inflator 22 is activated, the inflator 22 fills the airbag 23 with gas, and the gas in the airbag 23 cannot pass through the first solenoid valve, so the airbag 23 gradually expands and accumulates more and more gas. After the bubbling is over, turn off the flame spray gun 5 and the motor 12, the open flame disappears, the motor 12 stops rotating, and the clamping rod 9 also stops rotating. At this time, the temperature of the hot air gradually decreases, the first resistor 6, the second resistor and the third resistor The temperature of the airbag 23 also gradually decreases. When the temperature of the first resistor 6 and the third resistor drops below 100°C, the inflator 22 is turned off, the first solenoid valve is de-energized and opened. Under the action, it is quickly pressed into the telescopic rod 7, and the gas pushes the clamping rod 9 outward. The clamping rod 9 drives the pliers 24 and the wine glass close to the conveyor belt 14, when the second magnetic block 18 on the pliers 24 and the conveyor belt 14 When the first magnetic block 17 on the upper part contacts, the pliers 24 are fixed on the conveyor belt 14. Since the pliers 24 are splined with the clamping rod 9, the spline connection cannot fix the pliers 24 in the horizontal direction. The pliers 24 will move with the conveyor belt 14, and finally the pliers 24 will be separated from the clamping rod 9. When the temperature of the second resistor drops below 70°C, the second solenoid valve 8 is de-energized and opened. At this time, the clamping rod 9 moves in the direction of the telescopic rod 7 under the elastic restoring force of the first spring 10, and the clamping The gas in the holding rod 9 is discharged from the second solenoid valve 8. Finally, the new wine glass is clamped on the new pliers 24, and then the pliers 24 are splined to the clamping rod 9 to perform the next round of blowing processing.
[0027] In the above process, after the hot air rises, it will contact the top cover 2 and heat the accommodating cavity of the top cover 2. The sodium bicarbonate particles in the accommodating cavity are heated and decompose carbon dioxide. The carbon dioxide is emitted to the conveyor belt 14 through the air outlet pipe 4 The temperature of the wine glass is lowered, and the temperature of the carbon dioxide is not low after a certain heating, so it can prevent the wine glass from breaking due to excessive temperature difference when cooling the wine glass.
