Description

Technical Field

[0001] The utility model belongs to the technical field of glass bottle production, and particularly relates to a forming mechanism for small-caliber glass bottles. Background Technique

[0002] Glass bottles are the main packaging containers in the food, pharmaceutical, and chemical industries. They have good chemical stability; are easy to seal, with good airtightness, are transparent, and the contents can be observed from the outside; the glass raw materials mainly use quartz sand, plus other auxiliary materials, which are melted into a liquid state at high temperature, then injected into a mold, cooled, cut, and tempered to form a glass bottle. When the existing glass bottle forming molds are in use, usually only one glass bottle can be formed at a time. After forming, the glass bottle needs to be taken out, and then the next forming is carried out again, resulting in a relatively low overall forming efficiency of the glass bottle.

[0003] For this reason, an automatic forming machine for glass bottle production with the publication number of "CN217535804U" includes a working plate table and a forming mechanism; working plate table: a circular turntable is rotatably connected in the circular chute provided on its upper surface, and forming bases are evenly arranged on the upper surface of the circular turntable; forming mechanism: arranged on the left side of the bottom surface of the working plate table, forming molds are symmetrically arranged at the upper end of the forming mechanism, and the forming molds are arranged in cooperation with the forming bases; among them: a support is provided on the bottom surface of the working plate table, a controller is provided on the front side of the support, the input end of the controller is electrically connected to an external power supply, a first motor is installed on the right end of the bottom surface of the working plate table through a flange, and a circular groove is provided on the bottom surface of the circular turntable. This automatic forming machine for glass bottle production facilitates the automatic forming of glass bottles, ensures the quality of glass bottle forming, and greatly improves the forming efficiency of glass bottles.

[0004] However, for the above-mentioned automatic forming machine for glass bottle production, although the glass bottles are automatically formed, after forming, the electromagnet is powered off, the second motor works to move the two forming molds away from each other, and then the first motor works to drive the circular turntable to rotate a certain angle, so that the forming base adjacent to the glass bottle rotates between the forming molds to continue the next forming. There are still the following obvious defects in the use process: the forming molds in the above are arranged on one side of the circular platform and can only extrude and form glass bottles one by one, and cannot extrude and blow-mold two or more glass bottles synchronously, so that mass production of glass bottles cannot be achieved. Content of the Utility Model

And elastic cooling air pipes are connected to the ends of the bottle body forming template A and the bottle body forming template B to achieve the effect of cooling the glass bottle with cold air after forming.

It can make multiple external blow molding heads correspond one by one to the vertical upper ends of the glass bottle forming mechanisms, synchronously place the molten glass vertically on the corresponding forming cavities between the bottle body forming template A and the bottle body forming template B, and use an external controller to control the cylinder parts to simultaneously close the molds of multiple glass forming mechanisms, so as to simultaneously extrude the molten glass into the glass forming mechanisms. Use multiple external blow molding heads to blow air into the multiple molten glasses for shaping and then demold them vertically onto the finished product conveyor belt and pass through in time. By repeating the above process for batch production of small-diameter glass bottles, batch forming production of small-diameter glass bottles can be achieved, and further the forming production efficiency of small-diameter glass bottles can be improved.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-3 , the present invention provides a technical solution: a small-diameter glass bottle forming mechanism, including a conveying frame 1, and a finished product conveying roller 2 arranged in the middle of the upper end of the conveying frame 1 for conveying and outputting the formed glass bottle parts. The forming die is arranged on both sides of the end of the finished product conveying roller 2, and is used for vertically conveying the small-diameter glass bottle at the forming port. And because the forming die almost adheres to both sides of the surface of the finished product conveyor belt 10, the phenomenon of tipping over will not occur. Both ends of the conveying frame 1 are provided with strip-shaped vertical plates 3. A plurality of mold clamping cylinders 11 can be equidistantly installed on one side of the strip-shaped vertical plate 3, so that the pneumatic plate 4 can be evenly stressed. The inner side walls of the strip-shaped vertical plates 3 are both provided with pneumatic plates 4 in strip structure for pushing the forming and extruding molds to close the mold, which can simultaneously push a plurality of bottle body forming templates A5 and bottle body forming templates B6 to simultaneously extrude, close the mold and blow-mold the molten glass. The side of the pneumatic plate 4 is provided with bottle body forming templates A5 and bottle body forming templates B6 for extruding and blow-molding the molten glass. The number of bottle body forming templates A5 and bottle body forming templates B6 on the pneumatic plate 4 can be set to two or more, and the number can be increased or decreased according to the requirements of mass production. After the molten glass is extruded and the mold is closed, blow molding is carried out. The bottle body forming templates A5 and bottle body forming templates B6 are provided with cold air cavities 7 for cold air to enter to cool the formed glass bottle body, and the formed small-diameter glass bottle can be cooled and shaped by cold air. One end of the outside of the strip-shaped vertical plate 3 is provided with a cold air blower 8 for providing cold air to enter the cold air cavity 7, and the cold air blower 8 can make cold air enter the cold air cavity 7 for the function of cooling.

[0020] On both sides of the center position at the end of the transfer rack 1, there are strip-shaped plate members 9. The finished product transfer roller 2 can be rotated to the inner side of the strip-shaped plate member 9, and one of them is driven by an external servo motor for transmission. The finished product transfer rollers 2 are symmetrically arranged and rotated on the inner side of the strip-shaped plate member 9, which can drive the finished product conveyor belt 10 to rotate to timely convey the finished product glass bottles. And there is a finished product conveyor belt 10 conveyed between the finished product transfer rollers 2, achieving the effect of automatically conveying the finished product glass bottles and enhancing the production efficiency. On the inner sides of the strip-shaped vertical plates 3 arranged on both sides of the end of the transfer rack 1, mold clamping cylinder members 11 are equidistantly arranged, which push the multiple bottle body forming templates A5 and bottle body forming templates B6 to move simultaneously for mold clamping, and then the production of small-caliber glass bottles in batches can be carried out. One end of the piston rod of the mold clamping cylinder member 11 is fixed on one side of the pneumatic plate member 4. The bottle body forming templates A5 and bottle body forming templates B6 are equidistantly arranged inside the pneumatic plate members 4 symmetrically arranged on the transfer rack 1, which is conducive to the simultaneous mold clamping actions of the bottle body forming templates A5 and bottle body forming templates B6. And both ends of the bottle body forming templates A5 and bottle body forming templates B6 are connected with elastic cooling air pipes 12, which is conducive to conveying cold air into the cold air cavities 7 in the bottle body forming templates A5 and bottle body forming templates B6 for cooling.

[0021] One end of each of the elastic cooling air pipes 12 penetrates through the strip-shaped vertical plates 3 on both sides of the end of the transfer rack 1 and is communicated with a cold air inlet pipe fitting 13. One side of the cold air inlet pipe fitting 13 is connected to the elastic cooling air pipe 12 to separate the cold air for conveying in multiple directions. And the elastic cooling air pipe 12 is communicated with the cold air cavity 7, so that the cold air enters the cold air cavity 7 to cool and shape the blow-molded glass bottles. At the bottom of the cold air cavity 7, there is an exhaust pipe 14 that penetrates to the outer bottom ends of the bottle body forming templates A5 and bottle body forming templates B6, which can discharge the cold air from the exhaust pipe 14. Since the caliber of the exhaust pipe 14 is small and the discharge is slow, the cold air can be concentrated in the cold air cavity 7 to cool the glass bottles. The cold air output port of the cold air blower 8 is connected with a conveying air pipe 15, and the other end of the conveying air pipe 15 is connected to the bottom surface of the cold air inlet pipe fitting 13 on both sides of the end of the transfer rack 1, achieving the effect of cooling and temperature reduction.

[0022] Specifically, during use, first, the external blow molding head is installed on the conveyor rack 1 using a bracket, and the blow molding heads are equidistantly arranged at the upper end of the finished product conveyor belt 10. The blow molding heads are vertically corresponding to the bottle body forming templates A5 and B6 that are equidistantly and symmetrically arranged inside the pneumatic plate member 4. Subsequently, the molten glass is vertically placed between the inner cavities of the bottle body forming templates A5 and B6 in sequence by the blow molding head. At the same time, the external controller controls the clamping cylinder member 11 to push the pneumatic plate member 4 to move towards each other, and the bottle body forming templates A5 and B6 move towards each other simultaneously for clamping. At this time, the bottle body forming templates A5 and B6 are clamped to extrude the molten glass into the cavity forming cavity, so as to realize the extrusion and clamping and shaping of more than two amounts of molten glass. And the external blow molding head blows air into multiple molten glasses in a batch at the same time, so that the molten glass fits and forms an image with the inner wall after being combined with the bottle body forming templates A5 and B6, and the gas is discharged from the clamping gap, so that a batch of small-diameter glass bottles can be blow molded synchronously, thereby improving the batch production efficiency of small-diameter glass bottles. Finally, the cold air is conveyed to each elastic cooling air pipe 12 through the cold air inlet pipe fitting 13 by the cold air blower 8, and the cold air enters the cold air cavity 7 to cool the shaped glass bottles. And the cold air continuously discharges from the small-diameter exhaust pipe 14. The cooled glass bottles are vertically placed on the finished product conveyor belt 10 by the separation of the bottle body forming templates A5 and B6, and the external motor drives the finished product conveyor roller 2 to drive the finished product conveyor belt 10 to transmit to realize the output transmission of the finished product glass bottles. By repeating the above working process, the batch production of small-diameter glass bottles can be carried out.

[0023] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
