[0026] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation manners.

[0027] As shown Figures 1 to 8 In this embodiment, a blow molding device with directional variable temperature includes an annular conveyor track 1, a feeding mechanism 2, a feeding mechanism 3, a loading mechanism 4, a turning-in mechanism 5, a pressing mechanism 6, a high-temperature baking mechanism 7, a directional variable temperature mechanism 8, a mold forming mechanism 9 and a turning-out mechanism 10. The directional variable temperature mechanism 8 is located between the high-temperature baking mechanism 7 and the mold forming mechanism 9. The directional variable temperature mechanism 8 includes two directional variable temperature frames 11, and the two directional variable temperature frames 11 are respectively located on both sides of the same section of the annular conveyor track 1. A heating component or a cooling component is installed on the directional variable temperature frame 11, and the heating component or the cooling component changes the temperature of the directional position of the preform 46.

[0028] In this application, the directional variable temperature frame 11 in the heating component and the cooling component is installed by choosing one of them. When the heating component is installed, the heating component is a heating tube 12, and the heating tube 12 is vertically installed on the directional variable temperature frame 11. When the cooling component is installed, the cooling component is a cooling tube, and the cooling tube is vertically installed on the directional variable temperature frame 11. A variable temperature outer cover is fixed on the outside of the directional variable temperature frame 11.

[0029] When the preform 46 moves through the revolution of the annular conveyor track 1, the jig gear 47 on the annular conveyor track 1 drives the preform 46 to rotate. Then it enters the high-temperature baking mechanism 7 for high-temperature treatment. Installing the directional variable temperature mechanism 8 before the outlet of the high-temperature baking mechanism 7 and before the mold forming mechanism 9 does not affect the current entire production line, reduces the change of the production line, and by changing the temperature on different special-shaped surfaces of the preform 46, it makes the heat reception uniform during the special-shaped forming process, maintains the consistency of the wall thickness, and optimizes the wall thickness of the asymmetric bottle body.

[0030] Specifically, the feeding mechanism 2 includes a storage bin 13 and a lifting track 14. The lower end of the lifting track 14 is located at the inner bottom of the storage bin 13. Lifting plates 15 are arranged at equal intervals on the lifting track 14. A lifting motor 16 is installed at the lower end of the lifting track 14. The lifting motor 16 controls the operation of the lifting track 14 through a sprocket and a chain. The lifting motor 16 provides power to control the rotation of the lifting track 14, and the lifting plate 15 lifts the preform 46 in the storage bin 13 into the feeding mechanism 3.

[0031] The feeding mechanism 3 includes an inclined feeding chute 17 and an inclined sliding chute 18. A feeding wheel 19 is rotatably connected to the inside of the inclined feeding chute 17. A feeding motor 20 is installed below the inclined feeding chute 17. The feeding motor 20 controls the rotation of the feeding wheel 19 through a pulley and a belt. The upper end of the inclined sliding chute 18 is connected to the lower end of the inclined feeding chute 17. The preform 46 rolls from the high place to the low place of the inclined feeding chute 17. The feeding motor 20 controls the rotation of the feeding wheel 19 to place the preforms 46 into the inclined sliding chute 18 one by one for arrangement, which is convenient for inputting into the loading mechanism 4.

[0032] The loading mechanism 4 includes a loading chain 21 and a loading fixing frame 22. One end of the loading fixing frame 22 is equipped with a loading motor 23. The driving end of the loading motor 23 controls the movement of the loading chain 21 around the loading fixing frame 22. A loading clamping position 24 is installed on the loading chain 21. Preforms 46 are input one by one from the inclined chute 18 into the loading clamping position 24. The loading motor 23 controls the lateral movement of the loading clamping position 24 to receive the next loading clamping position 24. After a batch of multiple preforms 46 are loaded into the loading clamping position 24, it waits to be turned into the annular conveying track 1.

[0033] The turning-in mechanism 5 includes a turning-in bottom plate 25, a turning-in moving seat 26 and a turning-in lifting seat 27. A turning-in moving slide rail 28 is installed on the turning-in bottom plate 25. The turning-in moving seat 26 moves on the turning-in moving slide rail 28. A turning-in lifting cylinder 29 is fixed on the turning-in moving seat 26. The turning-in lifting seat 27 is connected to the driving end of the turning-in lifting cylinder 29. A turning-in rotating shaft 30 is connected to the turning-in lifting seat 27 by a bearing. Turning-in clamping jaws 31 are fixed at equal intervals on the turning-in rotating shaft 30. The turning-in moving seat 26 approaches the loading mechanism 4 under the action of the turning-in moving slide rail 28. The turning-in clamping jaws 31 clamp a batch of preforms 46. The turning-in rotating shaft 30 rotates, and the turning-in clamping jaws 31 turn the preforms 46 and sleigh them on the carrier 48 of the annular conveying track 1. Then the turning-in clamping jaws 31 are opened and returned to the original position to wait for the next batch of preforms 46.

[0034] The pressing mechanism 6 includes a pressing support 32 and a pressing plate 33. A pressing cylinder 34 is installed at the upper end of the pressing support 32. The driving end of the pressing cylinder 34 is vertically downward and connected to the pressing plate 33. A pressing block 35 is installed on the pressing plate 33. A pressing spring is connected between the pressing block 35 and the pressing plate 33. The pressing cylinder 34 controls the pressing plate 33 to move downward to press the pressing block 35 on the turned-in preforms 46 to ensure the stable position of the preforms 46.

[0035] The mold forming mechanism 9 includes a mold slide rail 36, a front mold 37 and a rear mold 38. The front mold 37 and the rear mold 38 slide towards each other on the mold slide rail 36. The front mold 37 and the rear mold 38 are respectively on both sides of the annular conveying track 1. The preforms 46 that have undergone high-temperature treatment and directional temperature-changing treatment enter between the front mold 37 and the rear mold 38 for mold closing and blow molding.

[0036] The turning-out mechanism 10 includes a turning-out bottom plate 39, a turning-out moving seat 40, and a turning-out lifting seat 41. A turning-out moving slide rail 42 is installed on the turning-out bottom plate 39. The turning-out moving seat 40 moves on the turning-out moving slide rail 42. A turning-out lifting cylinder 43 is fixed on the turning-out moving seat 40. The turning-out lifting seat 41 is connected to the driving end of the turning-out lifting cylinder 43. A turning-out rotating shaft 44 is connected to the turning-out lifting seat 41 by a bearing. Turning-out grippers 45 are fixed at equal intervals on the turning-out rotating shaft 44. The turning-out moving seat 40 approaches the annular conveying rail 1 under the action of the turning-out moving slide rail 42. The turning-out grippers 45 pick up a batch of preforms 46. The turning-out rotating shaft 44 rotates, and the turning-out grippers 45 turn over and take out the preforms 46.

[0037] The production process is as follows:

[0038] All the preforms 46 are placed in the storage bin 13. The lifting track 14 raises the preforms 46 to the inclined feeding chute 17 through the lifting plate 15. When the preforms 46 roll to the lower end in the inclined feeding chute 17, the rotating feeding wheel 19 aligns the preforms 46 one by one and inputs them into the inclined sliding chute 18 to slide down. After the preforms 46 enter the loading position 24, the loading chain 21 moves horizontally, so that multiple loading positions 24 receive the preforms 46. Then the turning-in moving seat 26 approaches the loading fixing frame 22, and the turning-in grippers 31 pick up a batch of preforms 46. The turning-in rotating shaft 30 rotates 180°. The preforms 46 are turned over and buckled on the carrier 48 of the annular conveying rail 1. The pressing plate 33 moves downwards, and the preforms 46 are pressed tightly by the pressing block 35. The annular conveying rail 1 controls the movement of the carrier 48 under the action of the chain to achieve revolution. At the same time, the jig gear 47 on the carrier 48 drives the preforms 46 to achieve rotation. They enter the high-temperature baking mechanism 7 for comprehensive high-temperature treatment. After coming out, they enter the added directional variable-temperature mechanism 8. According to the shape of the bottle body to be formed, directional variable temperature is carried out in the appropriate direction and position (heating pipes 12 are used for heating and cooling pipes are used for cooling), changing the temperature of different positions of the preforms 46. Then they enter the mold for blow molding, ensuring that the thickness of each surface of the special-shaped bottle is consistent and no concave surface is generated. Finally, the bottle body is picked up by the turning-out grippers 45. After the turning-out rotating shaft 44 rotates 180°, the bottle body is taken off from the annular conveying rail 1.

[0039] It should be noted that the above specific implementation manners are only the preferred embodiments of the present invention and the applied technical principles. Any changes or substitutions that are easily conceivable by those skilled in the technical field within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention.
