Description

Technical Field

[0001] This utility model relates to the field of glass bottle making equipment technology, and in particular to a bottle mouth cooling device and a glass bottle making machine. Background Technology

[0002] The glass bottle making machine produces glass bottles as follows: The glass raw material is pressed upward by the punch in the stamping mold to form the bottle mouth and preform. Then the preform is flipped over and placed into the forming mold. High pressure air is introduced through the air blowing pipe of the air blowing head to inflate the preform and make it fit tightly into the inner cavity of the forming mold, thus shaping it into the final product.

[0003] Currently, after the preform is placed into the molding die, the bottle neck is still hot and not fully set because it has just been demolded from the stamping die. During cooling to a fixed bottle shape, inconsistencies in wall thickness and shape lead to inconsistent shrinkage, resulting in dimensions that do not meet standard requirements. Therefore, to accelerate the cooling of the bottle neck, existing technology incorporates heat dissipation grooves in the bottle neck mold of the molding die, using externally applied cooling air for cooling.

[0004] However, for bottle openings that are thick and deep, conventional heat dissipation devices are inefficient and uneven in heat dissipation, which can easily cause deviations in the bottle opening size. Utility Model Content

[0025] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this utility model, not all embodiments.

[0026] Reference Figures 1 to 4 As shown, this utility model provides a bottle mouth cooling device.

[0027] The bottle mouth cooling device includes an air blowing head 100 and an air blowing pipe 200.

[0028] Reference Figures 1 to 2 As shown, the air blowing head 100 has a mounting hole 110 that runs vertically through the middle. The bottom of the air blowing head 100 has an upwardly recessed cooling cavity 120. The mounting hole 110 connects downward to the cooling cavity 120. The cooling cavity 120 is a cylindrical cavity. The side wall of the cooling cavity 120 has multiple exhaust holes 121. Each exhaust hole 121 runs horizontally through the side wall of the cooling cavity 120. The multiple exhaust holes 121 are evenly spaced along the circumference of the cooling cavity 120.

[0029] An air blowing pipe 200 is installed in the mounting hole 110 and extends into the cooling chamber 120. The side wall of the air blowing pipe 200 is provided with a plurality of first air blowing holes 211. Each first air blowing hole 211 penetrates the side wall of the air blowing pipe 200 in the horizontal direction. The plurality of first air blowing holes 211 are evenly spaced along the circumference of the air blowing pipe 200, and all the first air blowing holes 211 are located in the cooling chamber 120. The bottom end of the air blowing pipe 200 is provided with a second air blowing hole 221 that penetrates vertically.

[0030] After the preform is placed into the molding mold, the air blowing head 100 is located on the periphery of the bottle mouth, and the air blowing pipe 200 is inserted into the preform from the bottle mouth. The second air blowing hole 221 of the air blowing pipe 200 blows air into the preform, causing the preform to inflate and fit tightly against the inner cavity of the molding mold. Meanwhile, the multiple first air blowing holes 211 on the side wall of the air blowing pipe 200 are directly opposite the bottle mouth. The cooling gas blown out by the first air blowing holes 211 flows upward along the inner wall of the bottle mouth. Then, the cooling gas flows along the space between the outer wall of the bottle mouth and the cooling cavity 120. Finally, the cooling gas is discharged from the exhaust hole 121. This can fully cool the bottle mouth during the glass bottle molding process, greatly improving the heat dissipation efficiency. The distribution of the multiple first air blowing holes 211 and the multiple exhaust holes 121 ensures uniform heat dissipation at the bottle mouth, thereby ensuring accurate bottle mouth dimensions.

[0031] In some embodiments, refer to Figures 1 to 4As shown, the air blowing pipe 200 includes a pipe body 210 and a pipe cap 220. The pipe body 210 is a circular pipe structure that runs vertically through the pipe. The top of the pipe body 210 is installed in the mounting hole 110, and the bottom of the pipe body 210 extends into the cooling chamber 120. The side wall of the pipe body 210 is provided with a plurality of first air blowing holes 211. Each first air blowing hole 211 runs horizontally through the side wall of the pipe body 210, and the plurality of first air blowing holes 211 are evenly spaced along the circumference of the pipe body 210. The pipe cap 220 is installed at the bottom end of the pipe body 210. The pipe cap 220 is provided with a second air blowing hole 221 that runs vertically through the pipe body 210, and the inner diameter of the pipe body 210 is larger than the diameter of the second air blowing hole 221.

[0032] The cap 220 forms a blocking structure at the bottom end of the tube body 210. The cap 220 blocks the downward flow of gas inside the tube body 210, which helps some of the gas blocked by the cap 220 to flow upward and be blown out from the multiple first air holes 211. This helps to increase the flow rate of the gas blown out from the first air holes 211 and improve the cooling effect of the air blowing tube 200 on the mouth of the glass bottle.

[0033] In some embodiments, refer to Figure 3 and Figure 4 As shown, the tube body 210 and the tube cap 220 are detachably connected.

[0034] For glass bottles with thin mouths or shallow depths, in order to improve the blowing efficiency of the blowing tube 200 on the glass bottle, the tube cap 220 can be removed from the bottom of the tube body 210, so that the tube body 210 can blow a large amount of gas into the glass bottle, reduce the amount of gas blown out of the first blowing hole 211 on the side wall of the tube body 210, and improve the bottle making efficiency.

[0035] In some embodiments, the cap 220 can be of various types, and all types of caps 220 can be matched to the bottom end of the tube body 210, while the diameter of the second air hole 221 of the various caps 220 is different from each other.

[0036] Different types of glass bottles have different bottle mouth thicknesses and depths. Various caps 220 can be used to match various types of glass bottles. By changing the cap 220, the diameter of the second air hole 221 can be changed, which helps to adjust the amount of gas blown out of the first air hole 211 and the amount of gas blown out of the second air hole 221. This helps to balance the cooling efficiency of the bottle mouth and the blowing efficiency of the glass bottle, and improve the blowing speed of the glass bottle while ensuring the bottle mouth size, thereby improving the bottle making efficiency.

[0037] In some embodiments, refer to Figures 1 to 4 As shown, the inner wall of the cap 220 is provided with an internal thread, and the outer wall of the bottom end of the pipe body 210 is provided with an external thread. The internal thread of the cap 220 and the external thread of the pipe body 210 are engaged.

[0038] The pipe body 210 and the pipe cap 220 are threaded together, which makes the disassembly and installation of the pipe cap 220 more convenient. The connection between the pipe cap 220 and the pipe body 210 has a high sealing performance, which reduces gas leakage from the gap between the pipe body 210 and the pipe cap 220 and ensures that gas is blown out from the first air hole 211 and the second air hole 221.

[0039] In some embodiments, refer to Figure 1 and Figure 2 As shown, the top of the cap 220 is provided with a downwardly recessed cavity 222, the cross-sectional area of ​​the cavity 222 gradually decreases from top to bottom along the horizontal direction, and the bottom of the cavity 222 is provided with a second air hole 221 that runs vertically through the cavity.

[0040] The concave cavity 222, which gradually narrows from top to bottom, helps the gas flowing downward in the tube 210 to gradually converge into the second blowing hole 221, which helps to increase the flow rate of the gas blown out of the second blowing hole 221, and helps to form a greater blowing force in the glass bottle, thereby improving the blowing efficiency of the glass bottle.

[0041] In some embodiments, refer to Figures 1 to 2 As shown, cavity 222 is a hemispherical cavity.

[0042] The inner wall of the concave cavity 222 of the hemispherical cavity has a relatively gentle narrowing trend from top to bottom and inward, which creates an obstruction effect on the airflow at the bottom of the hemispherical cavity, which helps to block some of the gas and blow it out from the first air hole 211.

[0043] In some embodiments, refer to Figures 1 to 2 As shown, the bottom end of the tube body 210 extends below the cooling chamber 120, and the tube cap 220 is located below the cooling chamber 120.

[0044] The second air inlet 221 of the cap 220 extends into the bottom or below the mouth of the glass bottle, ensuring that the second air inlet 221 blows gas into the glass bottle to inflate the glass bottle, and avoiding the gas blown out of the second air inlet 221 being affected by the gas flow blown out of the first air inlet 211.

[0045] In some embodiments, refer to Figures 1 to 2 As shown, all exhaust ports 121 are located at the same height, all first air inlets 221 are located at the same height, and the height of the first air inlet 211 is equal to or higher than the height of the exhaust ports 121.

[0046] The height of all first air inlets 211 is not lower than the height of exhaust inlets 121, which helps the gas blown out by the first air inlets 211 to flow upward along the inner wall of the glass bottle mouth and then downward along the outer wall of the bottle mouth, thereby improving the cooling effect of the glass bottle mouth.

[0047] This utility model also provides a glass bottle making machine, including the bottle mouth cooling device as described in the above embodiments.

[0048] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
