[0041] Combine the following Figures 1 to 10 , describes a multi-station production line for processing curved glass according to an embodiment of the present invention, comprising a heating furnace 1 and a conveying module 2;

[0042] The heating furnace 1 is provided with a working chamber 11 and an air duct 12 inside. The air duct 12 is arranged around the working chamber 11. The air duct 12 is connected with the working chamber 11 through a first air outlet 13. A heating module 3 is arranged inside the air duct 12.

[0043] The conveying module 2 includes a track assembly 21 and a traction trolley 22. The track assembly 21 is arranged throughout the working chamber 11, and the track assembly 21 extends to the left and right sides of the heating furnace 1 to the outside of the heating furnace 1. The traction trolley 22 is slidably arranged on the track assembly 21, and the traction trolley 22 is arranged on the left and right sides of the heating furnace 1. The traction trolley 22 is provided with a bending mold, and the bending mold is used to place the glass to be processed. The traction trolley 22 drives the bending mold to reciprocate between the outside and the inside of the heating furnace 1.

[0044] like Figure 1 , 5As shown in FIG. 7 , in the multi-station production line for processing bent glass, the traction trolleys 22 located on the left and right sides of the heating furnace 1 sequentially drive the bending molds with the glass to be processed into the working chamber 11 of the heating furnace 1 for processing. When the glass to be processed corresponding to the traction trolley 22 located on the left side of the heating furnace 1 is bent and formed, the traction trolley 22 returns from the working chamber 11 of the heating furnace 1 along the original route; at this time, the traction trolley 22 located on the right side of the heating furnace 1 transports the glass to be processed into the working chamber 11 of the heating furnace 1 for processing; when the glass to be processed corresponding to the traction trolley 22 located on the right side of the heating furnace 1 is heated in the working chamber 11, the traction trolley 22 located on the left side of the heating furnace 1 can place the glass to be processed on the bending mold again after returning, and after the glass to be processed corresponding to the traction trolley 22 located on the right side of the heating furnace 1 is bent and formed and returns along the original route, the traction trolley 22 located on the left side of the heating furnace 1 can immediately transport the glass to be processed into the working chamber 11, thereby improving production efficiency, thereby solving the problem of low production efficiency caused by the need to take out the processed bent glass first and then put the next piece of glass to be bent on the bending mold of the heating furnace 1 after each bending and forming of the glass.

[0045] The traction trolley 22 moves on the track assembly 21, and drives the bending mold with the glass to be processed to move. After the glass to be processed enters the working chamber 11, the heating module 3 is started, and the air of the atmospheric environment is heated by the heating module 3 in the air duct 12 to form hot air. The hot air enters the working chamber 11 through the first air outlet 13 and blows toward the glass to be processed. When the glass to be processed is heated to the glass softening temperature for bending, the glass to be processed is bent by the bending mold to form an outer shape along the shape of the bending mold.

[0046] In some embodiments, the conveying module 2 further includes a driving mechanism 23 and a traction seat 24, one end of the traction seat 24 is connected to the driving mechanism 23, and the other end of the traction seat 24 is connected to the traction trolley 22, and the driving mechanism 23 drives the traction trolley 22 to reciprocate on the track assembly 21 through the traction seat 24. In this embodiment, the driving mechanism 23 is a cylinder, and the traction seat 24 is a connecting piece between the output end of the driving mechanism 23 and the traction trolley 22. The driving mechanism 23 drives the traction trolley 22 to reciprocate on the track assembly 21 through the traction seat 24, thereby realizing the function of conveying the glass to be processed to the working chamber 11 or conveying the glass after bending and forming back to the original path.

[0047] It is worth noting that the conveying module 2 also includes a transmission mechanism 26, which includes a driving wheel 261, a driven wheel 262, a traction seat 24 and a transmission belt 263; the driving wheel 261 and the driven wheel 262 are both transmission-connected to the transmission belt 263; one end of the traction seat 24 is arranged outside the closed loop of the transmission belt 263 and is fixedly connected to the transmission belt 263, and the other end of the traction seat 24 is fixedly connected to the traction trolley 22.

[0048] like Figure 2 and 4 As shown, specifically, the driving mechanism 23 is a motor, and the driving wheel 261 is arranged on the output shaft of the driving mechanism 23. When the output shaft of the driving mechanism 23 rotates, the driving wheel 261 is driven to rotate, and the driving wheel 261 drives the driven wheel 262 to rotate and drives the transmission belt 263 to move. The transmission belt 263 drives the traction trolley 22 to move on the track assembly 21 through the traction seat 24. In this embodiment, when the driving wheel 261 corresponding to the traction trolley 22 located on the left side of the heating furnace 1 rotates clockwise, the traction trolley 22 moves in a direction close to the interior of the heating furnace 1, and when the driving wheel 261 rotates counterclockwise, the traction trolley 22 moves in a direction away from the interior of the heating furnace; when the driving wheel 261 corresponding to the traction trolley 22 located on the right side of the heating furnace 1 rotates counterclockwise, the traction trolley 22 moves in a direction close to the interior of the heating furnace 1, and when the driving wheel 261 rotates clockwise, the traction trolley 22 moves in a direction away from the interior of the heating furnace 1.

[0049] Optionally, the transmission mechanism 26 further includes a tensioning wheel 264 , which is disposed on a lower outer wall of the closed loop of the transmission belt 263 , and one end of the traction seat 24 is disposed on an upper outer wall of the closed loop of the transmission belt 263 .

[0050] The tension wheel 264 also tightens the transmission belt 263, so that the transmission belt 263 is not easy to fall off during operation. When the tension wheel 264 is arranged on the lower outer wall of the closed loop of the transmission belt 263, and one end of the traction seat 24 is arranged on the upper outer wall of the closed loop of the transmission belt 263, the traction seat 24 will not collide with the tension wheel 264 when following the movement of the transmission belt 263, thereby improving the stability of the transmission mechanism.

[0051] Specifically, Fig. 9As shown, the track assembly 21 includes a first track 211 and a second track 212, the first track 211 and the second track 212 pass through the working chamber 11 in parallel, the traction trolley 22 is slidably arranged on the first track 211 and the second track 212; the traction seat 24 is arranged between the first track 211 and the second track 212.

[0052] The traction trolley 22 is slidably arranged on the first track 211 and the second track 212, which ensures that the traction trolley 22 remains stable during driving and is not easy to tip over. In addition, the first track 211 and the second track 212 are arranged in parallel, which can ensure that the traction trolley 22 will not derail during driving. When the traction seat 24 is arranged between the first track 211 and the second track 212, the force transmitted to the traction trolley 22 by the driving mechanism 23 through the traction seat 24 acts on the middle of the traction trolley 22, so that the force distributed to the first track 211 and the second track 212 by the traction trolley 22 is balanced, so that the traction trolley 22 is not easy to tip over during driving.

[0053] Preferably, the transmission mechanism 26 is symmetrically arranged on the left and right sides of the exterior of the heating furnace 1, and the traction trolley 22 includes a placement plate 221 and an isolation plate 222. Figure 5 and 6 As shown, the bending mold is detachably connected to the placement plate 221, which is convenient for replacing different bending molds to process and shape glass of different sizes and different curvatures. After the traction trolley 22 enters the working chamber 11 and the glass to be processed is located at the heating position aligned with the heating module 3, since the isolation plate 222 is parallel to the furnace opening 17 of the heating furnace 1, the isolation plate 222 extends upward and the height of the isolation plate 222 is higher than the height of the furnace opening 17 of the heating furnace 1, the isolation plate 222 will fit the furnace opening 17 of the heating furnace 1, thereby blocking the heat in the heating furnace 1 and slowing down the heat loss. Preferably, the placement plate 221 and the isolation plate 222 are perpendicular to each other, so that the placement plate 221 is perpendicular to the furnace opening 17 of the heating furnace 1, so that the glass to be processed can enter the working chamber 11 perpendicular to the furnace opening 17 of the heating furnace 1, avoiding the collision between the glass to be processed and the frame of the furnace opening 17 of the heating furnace 1.

[0054] The bending die is detachably connected to the placement plate 221, the isolation plate 222 is arranged at one end of the placement plate 221 away from the working chamber 11, the isolation plate 222 extends upward and the height of the isolation plate 222 is higher than the height of the furnace opening 17 of the heating furnace 1, the isolation plate 222 is parallel to the furnace opening 17 of the heating furnace 1, and the traction seat 24 is connected to one end of the isolation plate 222 away from the heating furnace 1. It is worth noting that, since the traction seat is connected to one end of the isolation plate 222 away from the heating furnace 1, when the transmission belt 263 of the transmission mechanism 26 only needs to drive the isolation plate 222 of the traction trolley 22 to move to the furnace opening 17 of the heating furnace 1 through the traction seat 24, the placement plate 221 of the traction trolley 22 can be located inside the heating furnace 1. Therefore, the transmission mechanism 26 only needs to be symmetrically arranged on the left and right sides of the outside of the heating furnace 1, and the transmission mechanism 26 does not need to extend to the inside of the heating furnace 1, thereby reducing the cost.

[0055] In some embodiments, the furnace opening 17 of the heating furnace 1 is provided with a locking mechanism, and when the traction trolley 22 enters the working chamber 11, the locking mechanism locks the isolation plate 222. In the process of the heating module 3 heating the glass to be processed, the traction trolley 22 is locked to the heating furnace 1, which can prevent the traction trolley 22 from shifting and affecting the quality of the processing and molding of the glass to be processed. Since the locking mechanism locks the isolation plate 222 to the furnace opening 17 of the heating furnace 1, the locking mechanism can be set on the outer frame of the furnace opening 17 of the heating furnace 1, thereby avoiding damage to the locking mechanism during the heating process, and it is also convenient to manually unlock and lock the locking mechanism. Specifically, the locking mechanism is preferably a door lock.

[0056] A heating assembly 25 is disposed on a side of the isolation plate 222 facing the working chamber 11. Figure 1 and 3 As shown, the furnace door of the furnace opening 17 of the heating furnace 1 needs to be opened and closed, and it is difficult to set the heating component 25. The heating component 25 is set on the side of the isolation plate 222 facing the working chamber 11. After the traction trolley 22 enters the working chamber 11, the glass to be processed can be heated more comprehensively by the heating component 25 combined with the heating module 3, thereby improving the quality of glass bending. Preferably, the heating component 25 is a nickel-chromium wire.

[0057] It is worth noting that the air duct includes an air inlet side 121 and an air outlet side 122 sequentially arranged along the flow direction of the wind, the air outlet side 122 is connected to the working chamber 11 through the first air outlet 13, and the air inlet side 121 is connected to the working chamber 11 through the first air inlet 14;

[0058] The heating furnace 1 is further provided with a heat circulation module 4, and the heat circulation module 4 includes a circulation mechanism 41, and the circulation mechanism 41 is arranged in the air duct 12, and the second air outlet 411 of the circulation mechanism 41 is communicated with the air outlet side 122, and the second air inlet 412 of the circulation mechanism 41 is communicated with the air inlet side 121;

[0059] like Figure 7-9 As shown, during heating, the circulation mechanism 41 is activated, and the second air inlet 412 of the circulation mechanism 41 extracts air from the air inlet side 121 and discharges it to the air outlet side 122 through the second air outlet 411. At this time, the air pressure on the air inlet side 121 decreases, and the air in the working chamber 11 will enter the air inlet side 121 from the first air inlet 14. The air pressure on the air outlet side 122 increases, and the air on the air outlet side 122 will enter the working chamber 11 from the first air outlet 13, thereby realizing air circulation. Since the heating module 3 is arranged in the air duct 12, the air will be heated every time it circulates, thereby improving the effect of heating the glass to be processed. Specifically, the air duct 12 is provided with a plurality of first air inlets 14, and the plurality of first air inlets 14 simultaneously absorb the air in the working chamber 11, which can improve the efficiency of circulation. Specifically, the thermal circulation module 4 further includes an external fan 42, which is disposed on the outer frame of the heating furnace 1 and connected to the circulation mechanism 41. The external fan 42 is started to cause the circulation mechanism 41 to operate, thereby realizing air circulation in the working chamber 11 and the air duct 12. The external fan 42 is disposed on the outer frame of the heating furnace 1, which can prevent the external fan 42 from being damaged by heat, thereby increasing the service life of the external fan 42.

[0060] like Figure 7 and 8 As shown, the heating furnace 1 is provided with a plurality of air ducts 12 in sequence along the extension direction of the track assembly 21. It is worth noting that the air outlet side 122 of each air duct 12 is connected to the working chamber 11 through the first air outlet 13, and the air inlet side 121 of the air duct 12 is connected to the working chamber 11 through the first air inlet 14, and a circulation mechanism 41 is provided in each air duct 12. Providing a plurality of air ducts 12 can enhance the effect of air circulation and improve the heating efficiency.

[0061] Alternatively, if Fig. 9 As shown, the heating modules 3 are respectively arranged at the air inlet side 121 and the air outlet side 122 of the air duct 12. The air is heated by the heating module 3 at the air inlet side 121, which can increase the temperature of the air, so that the temperature of the air will not be too low when it reaches the air outlet side 122 after passing through the circulation mechanism 41, thereby improving the efficiency of heating the air by the heating module 3 at the air outlet side 122.

[0062] like Fig.10 As shown, the heating module 3 includes a fixing frame 32 and a plurality of heating wires 31. The fixing frame 32 is fixedly arranged in the air duct 12 and does not contact the inner wall of the air duct 12. The heating wires 31 are fixedly arranged in the fixing frame 32, and the heating wires 31 are fixed in the air duct 12 through the fixing frame 32. Specifically, the heating wire 31 is electrically connected to the power supply. After the power supply supplies power to the heating wire 31, the heating wire 31 generates heat, and the temperature of the air increases when passing through the heating wire 31. The setting of the fixing frame 32 can prevent the heating wire 31 from directly contacting the inner wall of the air duct 12 and reducing the heating effect of the heating wire 31. In addition, it can also prevent the high-temperature heating wire 31 from directly touching the inner wall of the air duct 12 and damaging the air duct 12. Multiple heating wires 31 generate heat at the same time, which can improve the heating efficiency of the air.

[0063] The heating module 3 further includes a thermocouple 33, which is mounted on the fixing frame 32 and arranged between two adjacent heating wires 31, or a plurality of heating wire groups are formed by forming a group of two or more heating wires 31, and the thermocouple 33 is arranged between two adjacent heating wire groups. Fig. 9 As shown, the thermocouple 33 is used to monitor the temperature of the air in the air duct 12 and feed it back to the host computer. The host computer compares the temperature of the air in the air duct 12 with the rated temperature to select the number of heating wires 31 to be connected. The thermocouple 33 is arranged between two heating wires 31, or between two adjacent groups of heating wires, and can be close to the heating wires 31, so as to more truly reflect the current temperature.

[0064] Preferably, Fig. 9 As shown, the first air outlet 13 is provided with an air outlet nozzle 131, and the air outlet nozzle 131 is arranged toward the working chamber 11, and the cross-sectional area of ​​the air outlet nozzle 131 gradually decreases from the side far from the working chamber 11 to the other side close to the working chamber 11. Hot air enters from the side with a large cross-sectional area of ​​the air outlet nozzle 131, and moves toward the side with a small cross-sectional area of ​​the air outlet nozzle 131. At this time, the flow rate of the hot air will gradually increase, so that it can be quickly blown to the glass to be processed in the working chamber 11, thereby improving the efficiency of heating the glass to be processed. Specifically, the air duct 12 is provided with a plurality of first air outlets 13, and each of the first air outlets 13 is provided with a corresponding air outlet nozzle 131. The hot air enters the corresponding air outlet nozzle 131 through the plurality of first air outlets 13 and blows toward the glass to be processed at the same time, thereby further improving the heating efficiency.

[0065] The top of the heating furnace 1 is provided with a damper device 16, which is connected to the air duct 12. The damper device 16 has the function of adjusting the wind pressure of the air duct 12. By adjusting the gate opening of the damper device 16, the excess air can be discharged to the outside, thereby achieving the effect of adjusting the wind pressure of the air duct 12.

[0066] Other structures and operations of a multi-station production line for processing bent glass according to an embodiment of the present invention are known to those skilled in the art and will not be described in detail here.
