Description

Technical Field

[0001] The invention relates to the technical field of glass processing, and in particular to a blowing air control valve for a glass blowing molding production line. Background Art

[0002] In the glass manufacturing industry system, the blowing molding process is a key link and is widely used in many fields such as architectural glass, daily glassware, glass crafts, and high-end optical glass components. From the common glass cups and vases in daily life, to the large-scale insulation glass used in building curtain walls, to the precise lenses in optical instruments, the blowing molding process, with its unique technical advantages, can shape a variety of glass shapes and specifications, meeting the diverse needs of different industries and different scenarios, and thus occupies a pivotal position in the entire glass manufacturing field. However, in the long-term actual operation process, the traditional glass blowing molding production line has gradually exposed a series of thorny problems closely related to the blowing gas control. These problems are like bottlenecks, which seriously restrict the further development of the glass manufacturing industry and urgently need to be overcome through innovative technologies. The traditional glass blowing gas control method often relies on a simple valve structure. During the blowing process, once the flame parameters need to be adjusted, the worker must stop the blowing action and operate the valve by hand, which not only takes time and reduces production efficiency, but also has limited manual operation accuracy and is difficult to accurately control the flame. Therefore, a blowing gas control valve for the glass blowing molding production line is designed.

[0003] The traditional manual adjustment method requires workers to stop blowing and operate the valves if they need to adjust the flame parameters during the product blowing process. This not only interrupts the continuity of the blowing process and wastes time, but also frequently interrupts the operation, making it difficult to ensure the stability of product quality. In addition, the existing technology usually only has one flame shape, which greatly limits the scope of application of the glass blowing process. It is difficult to take into account the diverse requirements of different processes for flame shapes, reducing production efficiency and product diversity. Summary of the invention

[0015] The present invention provides a blowing air control valve for a glass blowing forming production line, having the following beneficial effects: In the present invention, the oxygen and natural gas intake amounts of the cylindrical burner and the strip-shaped burner are independently controlled by the first to fourth control valves. Operators can accurately adjust the size, temperature, and combustion ratio of the flame with their feet according to the real-time requirements of the glass blowing process. Workers do not need to stop to adjust the flame during the process of blowing products, and they can use both hands to blow products, resulting in higher efficiency. For example, when blowing fine glass handicrafts, the subtle changes in the flame can be precisely controlled to ensure uniform heating of the glass and improve the product quality.

The lifting plate is driven to move up and down along the rail rod through the rotating rod and the swing plate, and fine adjustment can be carried out through the turnbuckle. This design ensures that the lifting plate installed with the control valve can stably adjust its height to adapt to the height requirements of different operators or the position requirements of specific blowing processes, improving the comfort and convenience of operation. The support can rotate on the fixed rod, and the threaded fit between the rotating rod and the adjusting screw can further finely adjust the angle of the support, enabling the installation angle of the control valve to be flexibly adjusted according to actual operation needs, ensuring that operators can control the flame at the best operation perspective and posture, reducing operation fatigue, and improving operation accuracy. The components such as the bracket, fixed frame, lifting seat, gearbox, and handwheel at the front end of the base constitute a manually adjustable height adjustment device. Operators can precisely adjust the height of the support plate by rotating the handwheel and using the transmission of the gearbox, facilitating users to adjust the height of the seat cushion according to their own height.

[0017] In addition, in the present invention, the second heat-insulating glass plate can be lifted along the toothed rail and has a unique dual function. When installing and disassembling workpieces, operators can raise the second heat-insulating glass plate to provide sufficient space for the loading and unloading of workpieces, facilitating quick and convenient operation; during the glass blowing process, lower the second heat-insulating glass plate to jointly form an effective heat-insulating barrier with the first heat-insulating glass plate, blocking the transfer of the flame and high temperature to the area where the operator is located, reducing the operating environment temperature, and reducing the fatigue and safety risks of the operator caused by high temperature, ensuring physical health and operation safety.

And two gearboxes 1622 are installed on the fixing frame 162 through bolts. The four lifting seats 1621 are connected and driven through the two gearboxes 1622. A handwheel 1623 is installed on the input shaft of the lifting seat 1621 near the left front of the fixing frame 162. The upper ends of the output shafts of the four lifting seats 1621 are all installed with support rods 163. The upper ends of the four support rods 163 are installed with a support plate 1631. A seat cushion 1632 is fixed on the support plate 1631. Its function is: when the operator rotates the handwheel 1623, the power is transmitted through the input shaft of the lifting seat 1621 and drives the four lifting seats 1621 to act synchronously through the transmission of the two gearboxes 1622. The output shafts of the four lifting seats 1621 drive the support rods 163 to lift and lower, thereby realizing the height adjustment of the support plate 1631 and the seat cushion 1632. This manual adjustment method enables the operator to accurately adjust the height of the seat cushion 1632 according to his own height and the actual processing requirements of the glass workpiece to achieve a comfortable operating posture.

[0029] Working principle of this embodiment: The first motor 131 on the base 1 starts, and the power is transmitted to the worm gear transmission box 13. Its output shaft drives the rotating rod 11 to rotate. The swing plate 111 on the rotating rod 11 swings accordingly, and the lifting plate 121 is pulled along the rail rod 12 to slide up and down through the flower basket screw 112, so as to adjust the height of the control valve installed on the lifting plate 121 to adapt to the operating habits of different operators or the requirements of specific process positions. Rotate the rotating column 143 on the rotating mount 14, and the adjusting screw 1431 rotates. Since it is threadedly engaged with the threaded hole on the rotating rod 1421, the rotating rod 1421 will move, and then drive the support 142 to rotate on the fixed rod 141, realizing fine adjustment of the installation angle of the control valve. The four groups of column rods 2 on the base 1 support the operation plate 21. A cylindrical burner port 211 and a strip-shaped burner port 212 are installed on the operation plate 21. The first control valve 15 and the fourth control valve 153 respectively control the oxygen and natural gas intake of the strip-shaped burner port 212; the second control valve 151 and the third control valve 152 respectively control the oxygen and natural gas intake of the cylindrical burner port 211. Operators can accurately control the size, temperature and combustion ratio of the flame by adjusting the opening degrees of these control valves according to the requirements of the glass blowing process. The strip-shaped flame generated by the strip-shaped burner port 212 is suitable for large-area heating and glass stretching operations;The cylindrical flame generated by the cylindrical burner 211 is suitable for local concentrated heating, such as sealing glass tubes and shaping small components. The operator toggles the lever 2313, causing the snap plate 2311 to rotate, overcoming the pressure of the elastic pressure rod 2312. The sliding plate 231 can slide on the toothed rail 23, driving the second heat-insulating glass plate 232 to move up and down. When it rises, it facilitates the loading and unloading of the workpiece. When it descends, it enhances the heat-insulating effect, jointly protecting the operator with the first heat-insulating glass plate 22. The piston rod of the third hydraulic rod 3531 on the seat plate 35 expands and contracts, driving the rotating ring 3512 to rotate. The contact block 3521 on the movable block 352 slides in the arc-shaped groove of the rotating ring 3512, causing the movable block 352 to move relatively, driving the clamping plate 3522 to clamp or release the glass workpiece. The piston rod of the first hydraulic rod 31 on the top plate 3 expands and contracts, driving the first fixed plate 32 to move vertically. The first position sensor 323 and the second position sensor 324 accurately sense the position of the first fixed plate 32. The second motor 327 drives the lead screw 326 to rotate. Since the lead screw 326 is threadedly engaged with the upper end of the moving seat 325, the rotation of the lead screw 326 will drive the moving seat 325 to move in the front-rear direction. The second hydraulic rod 331 can make precise left-right position adjustments according to the actual situation, bringing the relative position of the flame and the workpiece to the optimal state and improving the processing quality. The rotating shaft 341 on the moving frame 34 and the third motor 342 are driven by a synchronous belt, capable of driving the turntable 36 to rotate. The operator rotates the handwheel 1623, and the power is transmitted through the input shaft of the lifting seat 1621, transmitted through two sets of gearboxes 1622, causing the four sets of lifting seats 1621 to act synchronously. Its output shaft drives the support rod 163 to move up and down, thereby adjusting the heights of the support plate 1631 and the seat cushion 1632 to adapt to the heights of different operators and the processing requirements of the workpiece.;
