Description

Technical Field

[0001] This utility model belongs to the field of polyester bottle production, specifically a polyester bottle blow molding mechanism. Background Technology

[0002] Polyester bottle blow molding refers to the process of producing various bottle-shaped containers using polyester (usually polyethylene terephthalate, abbreviated as PET) material through blow molding. Polyester bottles are widely used in the food, beverage, pharmaceutical, and cosmetic industries. Due to their good transparency, chemical resistance, impact resistance, and recyclability, they have become a commonly used material in the packaging field.

[0003] In existing technologies, when blow molding polyester bottles, most processes can only produce a single preform at a time. After blow molding is completed, workers need to manually unload and remove the preform before the next preform can be blow molded. This process is cumbersome, does not improve processing efficiency, and the frequent operation by workers greatly increases the labor burden. Utility Model Content

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figure 1-6 A polyester bottle blow molding mechanism includes a base 1, a support frame 2 fixedly connected to one side of the top of the base 1, a blow molding frame 4 slidably connected to one side of the bottom of the support frame 2 via a limiting rod 3, blow molding heads 5 fixedly connected at equal intervals to the bottom of the blow molding frame 4, a lifting plate 6 provided below the blow molding frame 4, a limiting frame 7 slidably connected to the bottom of the lifting plate 6, clamping plates 8 slidably connected at equal intervals to one side of the inner side of the limiting frame 7, a blow molding mold 9 slidably connected to the top of the base 1 and below the limiting frame 7, and a transmission assembly provided on the top of the base 1.

[0023] Specifically, the transmission assembly includes an adjusting screw 10 and a linkage unit. The adjusting screw 10 is rotatably connected between the top of the base 1 and the support frame 2. A first motor 11 is fixedly connected to one side of the top of the support frame 2 via a mounting plate. The output end of the first motor 11 extends to the bottom of the support frame 2 and is fixedly connected to the adjusting screw 10. The blow molding frame 4 is threadedly connected to the outside of the adjusting screw 10. A first bidirectional screw 14 is rotatably connected inside the limiting frame 7. A second motor 15 is fixedly connected to one side of the outside of the limiting frame 7 via a mounting plate. The output end of the second motor 15 extends into the inside of the limiting frame 7 and is fixedly connected to the first bidirectional screw 14. The lever 14 is fixedly connected. Multiple sets of bidirectional threads are equidistantly arranged on the outside of the first bidirectional lead screw 14. Multiple sets of clamping plates 8 are respectively threaded to the outside of the corresponding bidirectional threads. An electric telescopic rod 16 is fixedly connected inside the lifting plate 6. The output end of the electric telescopic rod 16 is fixedly connected to the limit frame 7. The limit frame 7 can be raised and lowered through the linkage unit. The linkage unit includes a support rod 12. The support rod 12 is symmetrically fixedly connected to the top of the base 1 and located on both sides of the blow molding mold 9. The lifting plate 6 is slidably connected to the outside of the support rod 12. A spring 13 is provided on the outside of the support rod 12 and at the bottom of the lifting plate 6.

[0024] The above technical solution involves first connecting an external air blower to two corrugated pipes 19, then using an external feeding mechanism to push a set of polyester bottle preforms to the limiting frame 7, ensuring each preform is positioned between a single set of clamping plates 8. Next, the second motor 15 is started, its output driving the first bidirectional lead screw 14 to rotate. This causes the lead screw 14, through a threaded connection, to simultaneously move multiple sets of clamping plates 8 closer together until the multiple preforms are clamped. At this point, the second motor 15 is turned off, stopping the clamping plates 8. Then, the first motor 11 is started. The output end of 11 drives the adjusting screw 10 to rotate, causing the adjusting screw 10 to drive the blow molding frame 4 and the blow molding head 5 to descend through the threaded connection, while stretching the bellows 19 until the blow molding frame 4 descends to the point where it is in contact with the top of the lifting plate 6. At this time, multiple blow molding heads 5 can be inserted into the corresponding preforms, and the preforms can be sealed by the sealing rings on the outside of the blow molding heads 5. Then the blow molding frame 4 continues to move downward, pushing the lifting plate 6 and the limit frame 7 to descend, thereby driving the preforms to descend, while compressing the spring 13 to deform it, until the preforms are driven down between the two blow molding molds 9. At this time, the first power is turned off. Machine 11 stops the bottle preform from moving. Then, the third motor 18 is turned on. The output of the third motor 18 drives the second bidirectional lead screw 17 to rotate, causing the second bidirectional lead screw 17 to drive the two blow molding dies 9 to move inward until they merge, placing multiple bottle preforms in the corresponding mold slots 20. At this time, the blower is turned on to blow mold the bottle preforms. After molding, the blow molding die 9 is opened by reversing the above process, which then drives the blow molding frame 4 to rise. At the same time, under the rebound force of the spring 13, the lifting plate 6 and the limit frame 7 rise and reset, which can drive the molded preforms to move inward. The ester bottle rises, and after resetting, the electric telescopic rod 16 is activated. The output end of the electric telescopic rod 16 pushes the limiting frame 7 and the polyester bottle to move outward. When it moves above the collection box 21, the operation is reversed to open multiple sets of clamping plates 8, allowing multiple polyester bottles to fall into the collection box 21 for easy collection by staff. This device has a simple structure and can automatically blow-mold and unload bottle preforms without manual operation. It avoids the trouble of having staff unload and remove the bottles one by one after blow-molding the preforms, thus greatly reducing the burden of manual labor and improving processing efficiency.

[0025] Specifically, a second bidirectional lead screw 17 is rotatably connected to one side of the inside of the base 1. Two blow molding dies 9 are threaded to the outer sides of the second bidirectional lead screw 17. A third motor 18 is fixedly connected to the outer side of the base 1 via a mounting plate. The output end of the third motor 18 extends into the inside of the base 1 and is fixedly connected to the second bidirectional lead screw 17. A sealing ring is fixedly connected to the outside of the blow molding head 5. Corrugated pipes 19 are symmetrically fixedly connected to the top of the support frame 2. The bottom of the corrugated pipes 19 extends to the bottom of the support frame 2 and is fixedly connected to the blow molding frame 4. The corrugated pipes 19 and the blow molding head 5 are connected through an internal channel. Mold grooves 20 are equidistantly opened inside the blow molding die 9. A collection box 21 is fixedly connected to the top of the base 1 near the blow molding die 9.

[0026] The above technical solution can avoid air leakage during the blow molding process by setting the sealing ring, and the corrugated pipe 19 can be easily adapted to the lowering and raising of the blow molding frame 4.

[0027] In use, first connect the external air blower to the two corrugated pipes 19. The external feeding mechanism pushes a set of polyester bottle preforms to the limiting frame 7, ensuring each preform is positioned between a single set of clamping plates 8. Then, start the second motor 15. The output of the second motor 15 drives the first bidirectional lead screw 14 to rotate, causing the first bidirectional lead screw 14 to simultaneously move the multiple clamping plates 8 closer together through a threaded connection until the multiple polyester bottle preforms are clamped. At this point, turn off the second motor 15 to stop the clamping plates 8 from moving. Then, start the first motor 11. The output of the first motor 11 drives the adjusting lead screw 10 to rotate. This causes the adjusting screw 10 to lower the blow molding frame 4 and blow molding head 5 via a threaded connection, while simultaneously stretching the bellows 19 until the blow molding frame 4 descends to its position against the top of the lifting plate 6. At this point, multiple blow molding heads 5 can be inserted into the corresponding preforms, and the preforms can be sealed by the sealing rings on the outside of the blow molding heads 5. Then, the blow molding frame 4 continues to move downwards, pushing the lifting plate 6 and the limiting frame 7 to descend, thereby lowering the preforms and compressing the spring 13 to deform them, until the preforms descend between the two blow molding molds 9. At this point, the first motor 11 is turned off, stopping the preform movement. Then, the third motor 18 is turned on, and the third... The output of motor 18 drives the second bidirectional lead screw 17 to rotate, causing the second bidirectional lead screw 17 to drive the two blow molding molds 9 to move inward until they merge, placing multiple preforms in the corresponding mold slots 20. At this time, the blower is turned on to blow mold the preforms. After molding, the blow molding molds 9 are opened by reversing the above process, which then drives the blow molding frame 4 to rise. At the same time, under the rebound force of spring 13, the lifting plate 6 and the limiting frame 7 rise and reset, which in turn drives the molded polyester bottles to rise. After resetting, the electric telescopic rod 16 is activated, and the output of the electric telescopic rod 16 pushes the limiting frame 7. As the polyester bottles move outward, once they reach above the collection box 21, multiple clamping plates 8 open through the reverse process described above, allowing multiple polyester bottles to fall into the collection box 21 for easy collection by staff. This device has a simple structure and can automatically blow-mold and unload bottle preforms without manual operation, avoiding the hassle of having staff remove the bottles one by one after blow molding, thus greatly reducing the burden of manual labor and improving processing efficiency. The sealing ring prevents air leakage during the blow molding process, and the corrugated pipe 19 facilitates the descent and ascent of the blow molding frame 4.
