Description

Technical Field

[0001] The invention relates to the technical field of bottom supporting of bubble blowing machines, and more particularly to a fully automatic bottom supporting device for a glassware bubble blowing machine. Background Art

[0002] When manufacturing glassware, the raw materials need to be heated and melted to form a uniform glass liquid. The material droplets are then dropped into a primary mold and the parison is flipped over to a forming mold in preparation for blowing. A bubble blower is used to inject high-pressure air into the parison, causing it to expand and fit the inner wall of the mold to form the final shape, thus completing the glassware manufacturing process.

[0003] During the manufacturing process of glassware, a bottom supporting device is required to support the bottom of the formed glassware. However, the bottom supporting device of the prior art still has the following shortcomings when used:

[0004] First, the bottom support device in the prior art often only contacts the bottom of the glassware for support, which results in an unstable bottom support for the glassware. In addition, the bottom support device can only contact and cool the bottom of the glassware. The glassware body often requires airflow from an external device for air cooling. During this process, the airflow is blown perpendicularly or nearly perpendicularly to the bottle body for cooling. The external force perpendicular to the bottle body can easily cause the glassware, which has not yet been fully cooled, to deform, thereby affecting the glassware manufacturing process.

[0005] Secondly, in the prior art, when the bottom supporting device is engaged with the mold, there is no positioning structure to ensure a more stable engagement between the bottom supporting device and the mold. When the bottom supporting device and the mold are engaged, relative displacement occurs, which often affects the blowing process of the glassware.

[0006] Therefore, in order to solve the above problems, it is necessary to provide a fully automatic bottom supporting device for a glassware bubble blowing machine. Summary of the Invention

[0039] Reference Figure 6-Figure 8 The annular air cooling mechanism 8 includes an annular groove 801, which is provided at the outer ring of the upper end of the bottom supporting member 701. An air injection channel 802 is provided at the bottom of the annular groove 801 in the bottom supporting member 701. The air injection channel 802 is communicated with the annular groove 801. An air duct blowing ring 803 is movably sleeved in the annular groove 801. The air duct direction of the air duct blowing ring 803 is along the direction of the inner wall cross-section of the bottom supporting member 701. A limiting groove 804 is provided at the bottom of the air duct blowing ring 803. An air hole 805 is provided at the bottom end of the air duct blowing ring 803.

[0040] When the front mold 601 and the rear mold 603 are separated, air flow is injected from the air injection channel 802 into the annular groove 801, thereby pushing the air duct blowing ring 803 upward and causing the air duct blowing ring 803 to leak upward from the annular groove 801. When the air duct blowing ring 803 reaches the highest point, air flow continues to be injected, causing the plunger 806 to lift upward, thereby opening the air hole 805. Air flow is injected from the air hole 805 into the air duct of the air duct blowing ring 803 and blown out along the inner wall cross-section of the bottom of the supporting member 701, thereby cooling the glassware in a direction approximately parallel to the surface of the glassware. This method can reduce external forces perpendicular to the surface of the glassware, thereby preventing the glassware from deformation. At the same time, the air duct blowing ring 803 leaking out from the outer circle of the upper end of the bottom supporting member 701 can better limit the glassware, making its supporting bottom more stable.

[0041] Reference Figures 6-10, the positioning reversing mechanism 9 includes a positioning groove 901, positioning grooves 901 are provided on both sides of the bottom supporting member 701, movable blocks 902 are movably sleeved in the positioning grooves 901, and a connecting channel 903 is provided in the movable block 902.

The movable block 90 2 When in contact with the limiting block 904, the channel of the connecting channel 903 is aligned with the air inlet end of the cooling curved channel 908 and the pipe end of the branch channel 907, thereby connecting the two. When the movable block 902 is not subjected to external force, the channel of the connecting channel 903 is aligned with the bottom end of the air injection channel 802 and the top end of the bottom air duct 906, thereby connecting the two. The channel end of the cooling curved channel 908 is aligned with the exhaust groove 610 and connected to each other. The positioning grooves 901 on both sides of the bottom supporting member 701 are respectively aligned with the positioning blocks 609 provided in the cavity groove 605.

After the connection is completed, the positioning block 609 pushes the movable block 902 to contact the limit block 904, so that the bottom air duct 906 is connected to the cooling curved channel 908, and the air flow from the second The gas is injected at the gas injection nozzle 703, injected into the cooling curved channel 908 through the air groove 702 and the bottom air duct 906, and discharged outward from the channel of the exhaust groove 610. In this way, the air flow circulates at the bottom of the bottom support part 701, thereby cooling it quickly. When the glassware is formed, the front mold 601 is separated from the rear mold 603, and the positioning block 609 is separated from the positioning groove 901. Under the action of the return spring 905, the bottom air duct 906 is connected to the gas injection channel 802, thereby achieving its annular air cooling effect.

[0043] The working principle of the present invention is as follows: when the front mold 601 and the rear mold 603 are molded together, the positioning blocks 609 on both sides will be aligned with the positioning grooves 901 on both sides of the bottom supporting member 701 and complete the fitting, thereby realizing the positioning process of the bottom supporting member 701, making the bottom supporting member 701 more firmly connected with the front mold 601 and the rear mold 603 to prevent them from relative displacement. After the joining is completed, the positioning blocks 609 push the movable blocks 902 to contact the limit blocks 904, so that the bottom air duct 906 is connected with the cooling curved channel 908, and the air flow is injected from the second air injection nozzle 703, injected into the cooling curved channel 908 through the air groove 702 and the bottom air duct 906, and discharged outwardly from the channel of the exhaust groove 610. In this way, the air flow circulates in the bottom of the bottom supporting member 701, so that it is cooled quickly. When the glassware is formed, the front mold 601 and the rear mold 603 are separated, and the positioning blocks 609 are removed from the positioning grooves 9 01 is separated, and under the action of the return spring 905, the bottom air duct 906 is connected to the air injection channel 802, and the air flow is injected from the air injection channel 802 into the annular groove 801, thereby pushing the air duct blowing ring 803 upward, causing the air duct blowing ring 803 to leak upward from the annular groove 801. When the air duct blowing ring 803 reaches the highest point, the air flow continues to be injected, causing the plunger 806 to lift upward, thereby opening the air hole 805, and the air flow is injected from the air hole 805 into the air duct of the air duct blowing ring 803, and blown out along the inner wall cross-section direction of the bottom support part 701, thereby cooling the glassware in a direction approximately parallel to the surface of the glassware bottle. This method can reduce the external force perpendicular to the surface of the glassware bottle, thereby preventing the glassware from deformation. At the same time, the air duct blowing ring 803 leaking out at the outer circle of the upper end of the bottom support part 701 can better limit the glassware, making its bottom support more stable.
