[0076] like Figure 7 As shown, the blowing assembly 91 includes: a blowing drive 911 (an air pump is selected), a blowing platform 912, an air supply pipe 913, a blowing head 914, and an air blow switch 915; the blowing platform 912 is fixed on the mounting frame 12; one end of the blowing drive 911 is fixed on the blowing platform 912, and the other end extends downward through the blowing platform 912 to be connected to the air supply pipe 913; the air supply pipe 913 is connected to the blowing head 914; the blowing head 914 is arranged vertically downward toward the second mold base mechanism 31; the air blow switch 915 is arranged at one end of the air supply pipe 913 close to the blowing head 914, that is, close to the lower end, and the connection between the air supply pipe 913 and the air pump is controlled by the air blow switch 915 to control whether the blow molding of the blank is plasticized; and in actual operation, the number of blowing assemblies 91 set is generally not less than two, so as to effectively shape the blow molded workpiece

[0077] like Figure 1 As shown, the air cooling component 92 includes a bellows 921, a blowing rod 922, and a blowing head 923; the bellows 921 is fixed on the mounting frame 12, one end of the blowing rod 922 is connected to the bellows 921, and the other end is connected to the blowing head 923; the blowing head 923 is arranged downward toward the second mold base mechanism 31, so as to perform air cooling operation on the blown product.

[0078] Working principle: For the convenience of explanation, according to the process, the present invention preferably installs four sets of first mold base mechanisms 21 on the pressing turntable 22, and installs six sets of second mold base mechanisms 31 that can be automatically opened and closed on the blowing turntable 22, and then cyclically delivers the pressed mouth mold 5 to the molding half mold 311 accurately through the intermediate clamping transfer unit 4.

[0079] Specifically, when the glass drop is sheared and dripped into the first die base mechanism 21 on the pressing and shifting unit 2, the turntable 22 of the pressing and shifting unit 2 quickly rotates the first die base mechanism 21 containing the drop to the stamping station. At this time, if the clamping and transferring unit 4 drives the mouth die 5 to close and descend into the mold cavity of the prototype half-mold 211, the clamping mechanism 6 clamps the edge of the mouth die 5 to improve the formability of the blank during pressing, and ensures that the half line of the workpiece is relatively small during blowing, which is convenient for the later workpiece processing operation; the stamping mechanism 7 quickly stamps downward, driving the outer wall of the edge pressing component 72 to fit with the mouth die 5, and the punch of the stamping mechanism 7 punches into the prototype half-mold 211 to punch the drop into the prototype blank;

[0080] The locking mechanism 6 releases the mouth mold 5, the clamping transfer unit 4 rises to hang the pressed blank on the mouth mold 5, and rotates it to above the blowing station of the blowing transfer unit 3. The mouth mold 5 rotating device descends to fit the mouth mold 5 with the inner wall of the forming half mold 311, and then the mouth mold 5 is opened, leaving the blank formed by the mouth stamping in the forming half mold 311. Then the mouth mold 5 rotating device rises, and the rotating table 33 rotates the forming half mold 311 to the next blowing station.

[0081] The blowing assembly 91 is running, the blowing head 914 descends to press the mouth ring of the blank, and compressed air is introduced to blow the product into shape to form the product. After the blowing time is up, the blowing head 914 is retracted, and the molding half mold 311 is rotated to the cooling station in a closed state, and the air cooling assembly 92 fully cools the product with air.

[0082] Then it rotates to the taking-out station, the forming half mold 311 opens automatically, and the product can be taken out from the forming half mold 311 manually or by a robot and placed on a conveyor, or directly into an annealing furnace, so as to complete the process from material unloading to product preparation. Similarly, the press-blow cycle of the product at the next station can be continuously cycled through a double-turntable press-blow machine.

[0083] In actual application, the whole machine integrates the design principles of mechanical, hydraulic, electrical, pneumatic components and other aspects, and relies on industrial computer PLC program to control the continuity and coordination of these actions. It can implement full automatic control of the glassware blow molding process, and transform the original complex and heavy operations of glassware in harsh environments such as high temperature into intelligent operations, which significantly optimizes the working environment and reduces labor intensity; the operation is simple and convenient, and during the operation, the parameters can be set in real time on the touch screen of the control panel according to the production process requirements, ensuring the correct and fast process adjustment process, and realizing the high coordination and unity of mechatronics.

[0084] Improve product quality: As this machine optimizes and integrates the pressure-blowing process of vessels and adds a series of process configurations, it better meets the surface process requirements of glassware, thereby greatly improving the grade of the product, making the wall thickness of the product uniform after pressure-blowing molding, without wrinkles, and the surface glossiness effect is better.

[0085] Reduce investment costs: The double-turntable press-blow machine provided by the present invention integrates a complete set of process configurations to achieve process requirements. It not only combines the common characteristics of a turntable press and a turntable blow-blow machine, but also greatly reduces the investment cost and labor cost of manufacturers through other auxiliary equipment such as a clamping transfer unit.

[0086] Improve production efficiency: At present, the production efficiency of the press-blow method equipment is low. Only by increasing the number of equipment can the output be increased. The double-turntable press-blow design of this machine not only reduces the energy loss in molding, but also has a fast molding speed and high production efficiency, thus achieving significant results in energy saving and material saving.

[0087] The successful development of a double-turntable press-blowing machine has filled the gap in domestic glass machinery and equipment, promoted the development and innovation of domestic glass machinery, improved the production efficiency and quality of domestic glassware, and reduced the cost of production products. It has broad market prospects, and its development and use will not only have rich economic benefits, but also good social benefits.

[0088] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
