[0002] Glass product press is a special mechanical equipment used to produce various glass products. It forms glass materials into set shapes and sizes by applying pressure.

[0003] The existing glass product press controls the various actions of the device through the servo system, and blows high-speed airflow on the upper surface of the glass product to lower the temperature of the glass product.

[0029] It also includes a flame-spraying mechanism 8, which is installed on the first support frame 301. The flame-spraying mechanism 8 includes a fixed clamping plate 801 and a second support frame 803. The bottom outer wall of the first support frame 301 is fixedly connected to the fixed clamping plate 801, and a gas valve 802 is installed on one side of the fixed clamping plate 801.

During liquid processing, excessive local stress in the glass product causes damage. After heating for a period of time, the gas flow rate of the gas valve 802 is reduced to reduce the flame at the high-temperature nozzle 805 to prevent repeated ignition and gas waste. At the same time, the drive motor 602 is started, and the output shaft of the drive motor 602 rotates counterclockwise, driving the rotating cylinder 407 to rotate clockwise through the gear set 603. The rotating cylinder 407 rotates through the first ventilation ring 406 and the first column to drive the rotating ring 401 to rotate. The rotation of the rotating ring 401 drives the support rod 402 to rotate synchronously. The support rod 402 drives the second clamping unit 404 to rotate through the second claw body 403. The rotation of the second clamping unit 404 drives the buffer mechanism 5 to rotate synchronously, and the rotating cylinder 407 rotates through the transmission ring 702 to drive the heated lower mold 703 to rotate synchronously until the heated lower mold 703 moves to below the output port of the electric melting furnace. At this time, the drive motor 602 is stopped.

[0031] After the heated lower mold 703 moves to below the output port of the electric melting furnace, the electric melting furnace opens the output port and flows out the molten glass, which then flows into the lower mold 703. When the volume of the flowing molten glass reaches the requirement for making glass products, the output port of the electric melting furnace is closed to stop the molten glass from flowing out, and the drive motor 602 is restarted to continue driving the above-mentioned buffer mechanism 5 and the lower mold 703 to rotate until the buffer mechanism 5 is located directly below the first claw body 305, at which time the drive motor 602 is stopped.

[0032] After the first claw body 305 is aligned with the buffer mechanism 5 in the vertical direction, the hydraulic drive unit 302 is started, and the hydraulic drive unit 302 transmits the hydraulic oil to the hydraulic cylinder 303 through the hydraulic pipeline, so that the hydraulic oil pushes the hydraulic rod 304 in the hydraulic cylinder 303 to move downward, and the hydraulic rod 304 moves downward through the first claw body 305 to drive the first housing 3061 to move synchronously, so that the first housing 3061 drives the first clamping block 3063 to move synchronously through the first sliding rod 3062, and the first clamping block 3063 moves downward to contact and squeeze the clamping column 502. In this process, the first clamping block 3063 slides along the outer wall of the clamping column 502 and drives the first sliding rod 3062 502, and the second clamping block 4043 is moved away from the clamping column 502 along the radial direction of the clamping column 502. At this time, the first spring is compressed, and then, under the push of the first spring, the first clamping block 3063 will slide along the outer wall of the clamping column 502 into the recessed part at the top of the clamping column 502 until the first spring is completely released. At this time, the arc surface of the first clamping block 3063 fits with the recessed part of the clamping column 502, and the bottom of the first claw body 305 contacts and squeezes the top of the clamping column 502, so that the clamping column 502 moves downward and squeezes the second clamping block 4043, so that the second clamping block 4043 moves away from the clamping column 502 along the radial direction of the clamping column 502, and at the same time drives the second sliding rod 4042 to move synchronously and compress the second spring. The rear clamping column 502 is separated from the second clamping block 4043, and the second spring is released to push the second clamping block 4043 and the second sliding rod 4042 to reset; the clamping column 502 moves downward through the first support plate 501 to drive the second support column 503 to move synchronously, and the second support column 503 moves to drive the second support plate 504 to slide downward, and the third sliding rod 506 moves with the second support plate 504 under the action of gravity, and the third sliding rod 506 moves through the third support plate 507 to drive the upper mold 508 to move synchronously, and the upper mold 508 moves downward to contact the lower mold 703 to complete the mold closing, and the upper mold 508 is molded with the lower mold 703, so that the glass melt in the lower mold 703 is squeezed The second support plate 504 moves to make the sliding claw 505 move synchronously, and finally the sliding claw 505 moves downward to contact and squeeze the top inclined surface of the sliding block 704, and the sliding block 704 is squeezed and slides, thereby approaching the center of the lower mold 703 and squeezing the fourth spring, and then the sliding claw 505 continues to move downward until it is separated from the sliding block 704. At this time, the fourth spring recovers and pushes the sliding block 704 to reset, so that the bottom inclined surface of the sliding block 704 contacts the sliding claw 505, and the sliding block 704 limits the sliding claw 505;It is worth noting that before the sliding block 704 completes the position limiting of the sliding claw 505, the upper mold 508 has been molded with the lower mold 703. During the process from the upper mold 508 and the lower mold 703 being molded together to the sliding block 704 completing the position limiting of the sliding claw 505, the second support plate 504 keeps moving downward, and the third support plate 507 is stationary, so that the second support plate 504 moves downward to squeeze the third spring. ;

[0033] After the shaping of the glass product is completed, the hydraulic drive unit 302 is started again. The hydraulic drive unit 302 draws out the hydraulic oil in the hydraulic cylinder 303 through the hydraulic pipeline, so that the hydraulic oil in the hydraulic cylinder 303 pulls the hydraulic rod 304 upward through the vacuum, and the hydraulic rod 304 moves upward through the first claw body 305 to drive the first shell 3061 to move synchronously, so that the first shell 3061 drives the first clamping block 3063 to move upward synchronously through the first sliding rod 3062. Since the bottom inclined surface of the sliding block 704 is relatively small, it is difficult for the sliding claw 505 to push the sliding block 704, so the sliding claw 505 is limited by the sliding block 704, and the sliding claw 505 passes through the first sliding rod 3062. The second support plate 504 limits the second support column 503, and then limits the clamping column 502 through the first support plate 501. The elastic coefficient of the first spring is small, so the first shell 3061 drives the first clamping block 3063 to slide upward along the outer wall of the clamping column 502, and drives the first sliding rod 3062 away from the clamping column 502 along the radial direction of the clamping column 502. At this time, the first spring is compressed, and then the first clamping block 3063 passes over the clamping column 502. The first spring is released and pushes the first clamping block 3063 to reset. As the hydraulic oil in the hydraulic cylinder 303 is continuously extracted, the hydraulic rod 304 drives the first clamping unit 306 to move and reset through the first claw body 305.

[0034] After the pressing mechanism 3 is reset, the driving motor 602 is started again, so that the driving motor 602 continues to drive the above-mentioned buffer mechanism 5 and the lower mold 703 to rotate. In this process, the first air channel and the second air channel of the first ventilation ring 406 rotate to Figure 8 At B, the first air channel of the first ventilation ring 406 is connected to the first cold air groove 4052, and the second air channel is connected to the first hot air groove 4053, so that the first cold air groove 4052 and the first hot air groove 4053 are both connected to the first heat exchange channel 5081. At the same time, the third air channel and the fourth air channel of the conveying ring 702 rotate to Fig.10At point B in the middle, the third air channel of the conveying ring 702 is connected with the second cold air groove 7012, and the fourth air channel is connected with the second hot air groove 7013, so that the second cold air groove 7012 and the second hot air groove 7013 are both connected with the second heat exchange channel 7031; then the first blower 4051 is started, and the first blower 4051 blows cold air into the first cold air groove 4052, and enters the first hose through the first air channel of the first ventilation ring 406, and then flows into the first heat exchange channel 5081. The upper mold 508 transfers the heat of the glass product to the cold air in the first heat exchange channel 5081 through heat transfer. The cold air moves from top to bottom, and the temperature gradually increases, so that the top of the glass product cools down faster and the bottom of the glass product cools down slower. The cold air absorbs heat in the first heat exchange channel 5081 and becomes hot air. The hot air enters the second air channel of the first ventilation ring 406 through the second hose and flows into the first hot air groove 4053; at the same time, the second blower 7011 is started, and the second blower The fan 7011 blows cold air into the second cold air groove 7012, and the cold air enters the second heat exchange channel 7031 through the third air channel of the conveying ring 702. The lower mold 703 transfers the heat of the glass product to the cold air in the second heat exchange channel 7031 through heat transfer. The cold air moves from bottom to top, and the temperature gradually increases, so that the bottom of the glass product cools down faster and the top of the glass product cools down slower. The cooperation of the first heat exchange channel 5081 and the second heat exchange channel 7031 can make the top and bottom of the glass product cool down synchronously, avoiding the slow heat change at the bottom of the glass product, which is easy to cause excessive stress in the glass product and make the glass product more easily broken; the cold air absorbs heat in the second heat exchange channel 7031 and becomes hot air, and the hot air enters the second hot air groove 7013 through the fourth air channel of the conveying ring 702. The two cold air reduce the temperature of the glass product to 600°C through heat exchange. At this time, the glass product has a good shape maintenance ability, and the glass product is finalized.

[0035] After the glass product is shaped, during the rotation of the buffer mechanism 5 and the lower mold 703, the second claw body 403 slides downward along the guide groove 201 and the support rod 402, and the movement of the second claw body 403 drives the second shell 4041 to move synchronously, and the second shell 4041 moves through the second sliding rod 4042 to drive the second clamping block 4043 to move synchronously. In this process, the second clamping block 4043 will contact the clamping column 502 and slide along the outer wall of the clamping column 502, and the sliding of the second clamping block 4043 drives the second sliding rod 4042 to move away from the clamping column 502 along the radial direction of the clamping column 502. At this time, the second spring is compressed, and then, under the push of the second spring, the second clamping block 4043 will slide along the outer wall of the clamping column 502 into the recess of the clamping column 502 until the second spring is completely released. At this time, the arc surface of the second clamping block 4043 is in contact with the recess of the clamping column 502, so that the second clamping block 4043 can grasp the buffer mechanism 5.

[0036] After the second clamping block 4043 grasps the buffer mechanism 5, the second claw body 403 slides upward along the guide groove 201 and the support rod 402, and the movement of the second claw body 403 drives the second housing 4041 to move synchronously, and the movement of the second housing 4041 drives the second clamping block 4043 to move synchronously through the second sliding rod 4042. In this process, due to the large elastic coefficient of the second spring, the sliding claw 505 moves upward to squeeze the sliding block 704, and the sliding block 704 is squeezed and slid, thereby approaching the center of the lower mold 703 and squeezing the fourth spring, and then the sliding claw 505 Continue to move upward until it just disengages from the sliding block 704. At this time, the fourth spring recovers and pushes the sliding block 704 to reset. At the same time, the second clamping block 4043 moves upward through the limit clamping column 502 to control the first support plate 501, so that the first support plate 501 drives the second support column 503 to move synchronously, and the second support column 503 moves through the second support plate 504 to drive the third sliding rod 506 to move. The third sliding rod 506 moves through the third support plate 507 to drive the upper mold 508 to move synchronously. During this period, the third spring is released to achieve the height reset of the buffer mechanism 5.

[0037] When the buffer mechanism 5 completes the height reset, the first air passage and the second air passage of the first ventilation ring 406 rotate to Figure 8 At the middle C, the first air channel of the first ventilation ring 406 is separated from the first cold air groove 4052, and the second air channel is separated from the first hot air groove 4053, so that the first cold air groove 4052 and the first hot air groove 4053 are separated from the first heat exchange channel 5081. At the same time, the third air channel and the fourth air channel of the conveying ring 702 rotate to Fig.10 At point C, the third air duct of the conveying ring 702 is separated from the second cold air groove 7012, and the fourth air duct is separated from the second hot air groove 7013, so that the second cold air groove 7012 and the second hot air groove 7013 are separated from the second heat exchange channel 7031; at this time, the driving motor 602 is stopped, and then the robot takes out the glass product from the lower mold 703 through the suction cup and moves it to other devices for subsequent processing.

[0038] After the glass product is taken out, the driving motor 602 is started again to continue to drive the buffer mechanism 5 and the lower mold 703 to rotate, so that the lower mold 703 is reset to the preheating position. In this process, the first air channel and the second air channel of the first ventilation ring 406 rotate to Figure 8 At D in the middle, the first air channel of the first ventilation ring 406 is connected to the first hot gas groove 4053, and the second air channel is connected to the first exhaust groove 4054, so that the first hot gas groove 4053 and the first exhaust groove 4054 are both connected to the first heat exchange channel 5081. At the same time, the third air channel and the fourth air channel of the conveying ring 702 rotate to Fig.10At D in the middle, the third air channel of the conveying ring 702 is connected to the second hot air groove 7013, and the fourth air channel is connected to the second exhaust groove 7014, so that the second hot air groove 7013 and the second exhaust groove 7014 are both connected to the second heat exchange channel 7031; the hot air in the first hot air groove 4053 enters the first hose through the first air channel of the first ventilation ring 406 and flows into the first heat exchange channel 5081, the upper mold 508 absorbs the heat in the hot air through heat transfer, and the hot air enters the second air channel through the second hose and finally flows out from the first exhaust groove 4054; at the same time, the hot air in the second hot air groove 7013 The hot air enters the second heat exchange channel 7031 through the third air channel, and the lower mold 703 absorbs the heat in the hot air through heat transfer, and the hot air flows out through the fourth air channel and the second exhaust groove 7014. The two streams of hot air preheat the upper mold 508 and the lower mold 703 through heat exchange. After the lower mold 703 is preheated, it can reach the specified temperature faster under the high-temperature nozzle 805, reducing the use of gas and improving the energy utilization efficiency; with the rotation of the above-mentioned buffer mechanism 5 and the lower mold 703, the lower mold 703 is reset, and the first air channel and the second air channel of the first ventilation ring 406 are rotated to Figure 8 At A in the middle, the first air channel of the first ventilation ring 406 is separated from the first hot gas groove 4053, and the second air channel is separated from the first exhaust groove 4054, so that the first hot gas groove 4053 and the first exhaust groove 4054 are separated from the first heat exchange channel 5081. At the same time, the third air channel and the fourth air channel of the conveying ring 702 rotate to Fig.10 At point A in the middle, the third air duct of the conveying ring 702 is separated from the second hot air groove 7013, and the fourth air duct is separated from the second exhaust groove 7014, so that the second hot air groove 7013 and the second exhaust groove 7014 are separated from the second heat exchange channel 7031, thereby realizing the alternating flow of hot and cold air in the first air duct and the second air duct of the first ventilation ring 406 and the third air duct and the fourth air duct of the conveying ring 702.

S3: Start the hydraulic drive unit 302, so that the first clamping block 3063 clamps the clamping column 502, and the bottom of the first claw body 305 pushes the clamping column 502 to move downward, so that the bottom inclined surface of the sliding clamping block 704 contacts the sliding claw 505, and at the same time, the upper mold 508 moves downward to contact the lower mold 703 to complete the mold closing, so that the glass melt is squeezed and formed, and the glass product is molded and the shape of the glass product is maintained; S4: The hydraulic drive unit 302 is started again to move and reset the first clamping unit 306, and the drive motor 602 is started again, and the first blower 4051 and the second blower 7011 are started to allow cold air to enter the first heat exchange channel 5081 and the second heat exchange channel 7031 to cool the glass product to 600° C. and fix the glass product.
