Once it is necessary to replace preforms with different diameters or specifications during the production process, it is necessary to stop the machine to replace the special preform clamping manipulator. This process not only takes a long time but also increases the number of production pauses, seriously affecting production efficiency. Content of the Utility Model

[0026] Please refer to Figures 1-3 ,

[0027] A preform loading mechanism includes a base 1. Four cylinders 1 are provided on the base 1. A support plate 3 is provided on the four cylinders 1 in total. On the front and rear sides of the upper surface of the support plate 3 are respectively a bearing seat 6 and a rotating motor 7. A rotating shaft 5 is fixed to the output end of the rotating motor 7. The other end of the rotating shaft 5 is connected to the bearing seat 6, and five evenly distributed embryo clamping manipulators 4 are fixedly connected to the outside of the rotating shaft 5.

[0028] The embryo clamping manipulator 4 consists of a clamping jaw part and a cylinder 3 402.

[0029] The clamping jaw part consists of a housing 401, two connecting rods 1 406, two connecting rods 2 404, and a connecting rod 3 403. Both the left and right sides of the connecting rod 3 403 are connected to the corresponding connecting rod 2 404 through shafts. The end of the connecting rod 2 404 away from the connecting rod 3 403 is connected to the connecting rod 1 406 through a shaft, and a shaft fixed to the housing 401 is inserted into the bent part of the connecting rod 1 406, and a tension spring 405 is arranged between the two connecting rods 1 406.

[0030] In this example, an embryo receiving bracket 9 is arranged on the outer side of the support plate 3 , a slide groove is arranged at the bottom of the embryo receiving bracket 9 and connected with the slide rail 8 , and a cylinder 2 10 is arranged on the right side of the embryo receiving bracket 9 .

[0031] Among them, the cylinder 2 10 pushes the embryo receiving bracket 9 to move left and right along the slide rail 8 to cooperate with the slideway of the embryo sorting mechanism.

[0032] In this example, a cylinder 3 402 is disposed inside the housing 401 , a hole is disposed in the middle of the connecting rod 3 403 for connection with the cylinder 3 402 , and a ring for hooking the two ends of the tension spring 405 is disposed at the bent portion of the connecting rod 1 406 .

[0033] It should be noted that cylinder three 402 provides power, connecting rod three 403 realizes linear motion, and connecting rod one 406 and tension spring 405 are responsible for transmitting force and maintaining the stability of the system. When connecting rod three 403 is pushed by cylinder three 402, the bent part of connecting rod one 406 and tension spring 405 work together to ensure the smooth operation of the system and proper torque transmission.

[0034] In this example, four cylinders 2 are provided on the base 1 for lifting and lowering the support plate 3 , and the bearing seat 6 is fixedly connected to the support plate 3 .

[0035] It should be noted that the bearing seat 6 is fixedly connected to the support plate 3 to ensure that the preform remains stable during the lifting process and prevent the preform from being damaged due to shaking.

[0036] In this example, a straight plate 11 and an inclined plate 12 are provided on the embryo receiving bracket 9, and a U-shaped embryo receiving groove corresponding to the embryo clamping robot 4 is provided on the straight plate 11 and the inclined plate 12, and the notch of the U-shaped embryo receiving groove cooperates with the slideway of the embryo mechanism of the bottle blowing mechanism.

[0037] It should be noted that the straight plate 11 can be used to place the preform stably on the bracket, and the inclined plate 12 increases the downward force of the preform so that the preform can automatically slide to the position of the preform clamping robot 4, and the U-shaped groove enables the preform clamping robot 4 to clamp the preform more accurately.

[0038] In this example, the rotating shaft 5 passes through five embryo clamping robots, and support blocks 13 are provided at the left and right ends of the rotating shaft 5 , and clamping plates are also provided at the upper and lower ends of the support block 13 for fixing the embryo clamping robots 4 .

[0039] It should be noted that the rotating shaft 5 and the clamping plate together form a solid supporting structure, so that the embryo clamping robot 4 can smoothly rotate and move on the rotating shaft 5 to complete the processing task of the workpiece.

[0040] In summary, during the startup process of the bottle blowing machine, the blank sorting mechanism is responsible for orderly transporting the preforms to the position of the preform receiving bracket 9. Subsequently, the feeding mechanism descends under the action of the second cylinder, and the third cylinder 402 inside the housing 401 pushes the third connecting rod 403 to move linearly forward. The force exerted by the third connecting rod 403 is transmitted to the first connecting rod 406 through the second connecting rod 404, causing the first connecting rod 406 to open the clamping jaws outward. Once the clamping jaws successfully grip the preform, the piston rod of the third cylinder 402 retracts, and the tension spring 405 begins to work, providing an inward clamping force to ensure that the clamping jaws can firmly hold the preform, thus completing the stable grasping of the preform.

[0041] Beneficial effects:

[0042] For this preform feeding mechanism, through the design of the clamping jaw part, the preform clamping manipulator can adapt to preforms of different diameters or specifications without the need to replace the dedicated preform clamping manipulator, greatly improving the production efficiency; through the design of the energy supply part, the preform clamping manipulator can automatically lock, preventing excessive force from damaging the preform.

[0043] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
