Description

Technical Field

[0001] The present application relates to the technical field of blow molding equipment, and in particular to a blow molding device for a hollow container. Background Art

[0002] Extrusion blown hollow containers such as bottles and barrels are generally blown with 8 bar compressed air. The mold is designed with water channels, and chilled water is introduced to take away the heat to form the plastic products. Under the condition that the mold water channel design is relatively perfect, the blowing air pressure, chilled water pressure and water temperature are normal, in order to improve the manufacturing cycle, domestic and foreign manufacturers have used 8 bar compressed air at minus 25 degrees to blow hollow containers, and use intermittent blowing to take away the heat, such as blowing for 3S and exhausting for 0.5S. Practice has proved that it effectively shortens the manufacturing cycle by about 15%.

[0003] However, the current cold air blowing technology for hollow containers has shortcomings: when using compressed air at minus 25 degrees to blow containers, the existing blowing needle can only ensure the flow of gas at the blowing port of the container, blowing away heat in a row, while the intermittent blowing effect is limited at the bottom of the container or farther away, and most blowing needles cannot adjust the extension length of the blowing needle according to the height of the hollow container bottle or barrel, affecting the production speed of the hollow container.

[0032] Reference Figure 2 and Figure 3 The end of the base 1 away from the blow pipe 2 is connected with a cooler and a booster pump. The base 1 is quickly positioned by a positioning column 11, so that the base 1 is pressed against the blowing port of the hollow container on the mold, and the sealing with the blowing port of the mold is enhanced by a first sealing gasket 12. The length of the blow pipe 2 is adjusted according to the height of the hollow container by the adjusting device 3, so that the blow pipe 2 moves away from the blowing port and close to the bottom of the hollow container, thereby enhancing the air flow at the bottom of the hollow container and enhancing the blow molding effect of the hollow container.

[0033] A slide 13 is fixedly mounted on the base 1 , the slide 13 passes through the positioning column 11 , the blowpipe 2 passes through the slide 13 and is slidably connected to the slide 13 , a sealing platform 131 is arranged at the bottom end of the slide 13 , and a second sealing gasket 132 is fixedly mounted on the sealing platform 131 .

[0034] Refer to 3. Figure 4 and Figure 5 The adjusting device 3 includes a first rotating shaft 31, which is rotatably mounted on the base 1. A handle 311 is fixedly mounted on one end of the first rotating shaft 31 located outside the base 1, and a first gear 32 is fixedly mounted on one end of the first rotating shaft 31 away from the handle 311. A second rotating shaft 331 is rotatably mounted on the base 1, and the second rotating shaft 331 is arranged between the first rotating shaft 31 and the blowpipe 2. A second gear 332 is fixedly mounted on one end of the second rotating shaft 331 close to the first rotating shaft 31, and the second gear 332 is meshedly connected with the first gear 32. A third gear 333 is fixedly mounted on one end of the second rotating shaft 331 close to the blowpipe 2.

[0035] The blow pipe 2 is integrally manufactured with an adjustment groove 21 , the length of which is less than the length of the slide 13 , and a rack 22 is fixedly installed in the adjustment groove 21 on the blow pipe 2 , and the blow pipe 2 is meshedly connected with the third gear 333 through the rack 22 .

[0036] When it is necessary to adjust the height of the blow pipe 2 in the hollow container, the handle 311 is rotated to control the first shaft 31 to rotate, the first gear 32 rotates following the first shaft 31, the first gear 32 drives the second gear 332 to rotate, and the third gear 333 rotates following the second gear 332. The third gear 333 engages with the rack 22 to make the blow pipe 2 slide on the slide 13, thereby achieving the adjustment of the length of the blow pipe 2 extending into the hollow container, which is beneficial to improving the convenience of the blowing processing device for the hollow container during use.

[0037] Reference Figure 6 and Figure 7 A locking assembly 34 for fixing the first rotating shaft 31 is installed on the base 1, and the locking assembly 34 includes a mounting tube 341, which is fixedly mounted on the base 1, and a first connecting rod 342 is movably mounted on the mounting tube 341, one end of the first connecting rod 342 passes through the base 1 and extends out of the outside of the base 1, and the first connecting rod 342 is fixedly mounted with a limiting plate 343 at one end of the mounting tube 341, and a spring 344 is sleeved on the first connecting rod 342, one end of the spring 344 is fixedly connected to the limiting plate 343, and the other end of the spring 344 is fixedly connected to the mounting tube 341, and one end of the first connecting rod 342 located on the outside of the base 1 is fixedly connected to a second connecting rod 345, and the second connecting rod 345 is arranged perpendicular to the first connecting rod 342, and a locking block 346 is fixedly mounted on the side of the second connecting rod 345 close to the base 1, and a locking hole 3111 is provided on the rotating handle 311 to cooperate with the locking block 346.

[0038] When it is necessary to rotate the handle 311, pull the second connecting rod 345 in the direction away from the base 1, and the second connecting rod 345 drives the first connecting rod 342 to slide on the mounting tube 341, and the first connecting rod 342 drives the limit plate 343 to move the extrusion spring 344, at which time the locking block 346 is disengaged from the locking hole 3111, and the second connecting rod 345 is rotated to disengage from the top of the handle 311, and the second connecting rod 345 is released to fix the second connecting rod 345 on the base 1 through the spring 344, so that the handle 311 can be quickly rotated to adjust the blowpipe 2. When the blow pipe 2 is adjusted to the specified length, pull the second connecting rod 345 away from the base 1, rotate the second connecting rod 345 to make the locking block 346 enter the locking hole 3111, release the second connecting rod 345, and again tighten the second connecting rod 345 on the turning handle 311 through the action of the spring 344, so as to quickly fix the turning handle 311 and prevent the turning handle 311 from rotating during the use of the blow pipe 2 to change the length of the blow pipe 2 and affect the blowing process of the hollow container.
