Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical packaging equipment technology, specifically a punching device. Background Technology

[0002] Blow-fill-seal (BFS) packaging machines are widely used in the pharmaceutical, cosmetic and other fields. The production process of this equipment is as follows: plastic particles enter the extrusion screw and are heated to about 170 degrees Celsius. After heating, the plastic particles melt and become flowing resin. As the screw rotates, the molten resin is extruded from the die head and continuously extruded into a tube shape. The tube preform forms a bottle in the mold.

[0003] After the existing tube preform is formed into a bottle in the mold, some of the tube preform forms waste material that covers the bottle. This waste material is difficult to clean quickly and requires manual cleaning, which leads to problems that affect the bottle production efficiency.

[0004] Therefore, a solution is needed. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 This utility model provides a technical solution:

[0021] Example 1

[0022] The problem to be solved is that after the existing tube preform is formed into a bottle in the mold, some of the tube preform forms waste material that covers the bottle. This waste material is difficult to clean quickly and requires manual cleaning, which affects the bottle production efficiency.

[0023] The solution is as follows: A punching device includes a device body 1, which includes a support frame 2, a die device 3, a punch 4, and a bottle holder device 5. The die device 3 is installed inside the right end of the support frame 2, the punch 4 is installed inside the left end of the support frame 2, and the bottle holder device 5 is installed inside the support frame 2 and located between the die device 3 and the punch 4. The die device 3 includes a drive platform 6, a mounting platform 7, a die module 8, a hydraulic cylinder 9, a first guide post 10, and a support block 12. The support block 12 is provided in a set, and a set of support blocks 12 is provided. The drive platform 6 is welded to the left end of a set of support blocks 12 inside the welding support frame 2. The mounting platform 7 is fixed to the left end of the drive platform 6 by screws. The recessed module 8 is fixed to the left end of the mounting platform 7 by screws. The hydraulic cylinder 9 is fixed to the right end of the drive platform 6. A set of first guide pillars 10 is provided and a set of first guide pillars 10 is installed on the right end of the drive platform 6. The right end of the set of first guide pillars 10 is located outside the support frame 2. A guide pillar stabilizing block 11 is welded between the outer ends of the set of first guide pillars 10. The guide pillar stabilizing block 11 has a U-shaped structure.

[0024] Analysis of the above: The hydraulic cylinder 9 provides power to move the drive platform 6 supported by the support block 12, which in turn moves the mounting platform 7 and the concave module 8 closer to the punch 4. The separation of waste material and bottle is achieved through the cooperation of the concave and punch. A set of first guide pillars 10 and U-shaped guide pillar stabilizing blocks 11 guide the movement of the drive platform 6, ensuring the accuracy of the punching position. During punching, the hydraulic cylinder 9 extends, driving the concave module 8 to move towards the punch 4 to complete the punching. After punching, the hydraulic cylinder 9 retracts, driving the concave module 8 to retract, making room for the bottle support action. When adjusting the punching accuracy, the cooperation between the guide pillars and the drive platform 6 and the stroke of the hydraulic cylinder 9 can be checked. The driving power of the hydraulic cylinder 9 is stable and the punching force is sufficient. The first guide pillars 10 and stabilizing blocks 11 make the movement of the concave module 8 precise, resulting in good punching separation effect. This replaces manual stripping of waste material, improving both efficiency and accuracy.

The first drive plate 15 is provided in one set and is respectively installed at the front end and the rear end of the first bottle holder 13. The second drive plate 16 is provided in one set and is respectively installed at the front end and the rear end of the second bottle holder 14. The first bottle holder 13 and the second bottle holder 14 are respectively sleeved on the second guide post 19 through the first drive plate 15 and the second drive plate 16. The thin cylinder 18 is installed at the right end of the second drive plate 16 and the driving end of the thin cylinder 18 is fixed to the first drive plate 15. The large cylinder 17 is fixed at the right end of the support frame 2 and the large cylinder 17 is fixed at the right end of the second drive plate 16.

[0027] Analysis of the above content: The large cylinder 17 provides long-stroke power, driving the second drive plate 16 and the second bottle holder 14 to move along the second guide post 19; the thin cylinder 18 drives the first drive plate 15 and the first bottle holder 13 to clamp the bottle, and then transports the bottle to the punch 4.

[0034] Working principle: A group of bottles with waste material is transferred from above to the first bottle holder 13 and the second bottle holder 14 by a conveyor clamp. The thin cylinder 18 retracts, closing the first bottle holder 13 and the second bottle holder 14 and clamping the bottles. Then, the large cylinder 17 advances, moving the first bottle holder 13 and the second bottle holder 14 to the punch 4, where the bottles fit against the punch 4. Then, the hydraulic cylinder 9 advances, pushing the drive table 6 supported by the support block 12 to move, moving the mounting table 7 and the die plate 8 closer to the punch 4. Through the cooperation of the die and the die, the waste material and the bottles are separated. After separation, the die device resets, and then the thin cylinder 18 advances, opening the first bottle holder 13 and the second bottle holder 14. The conveyor clamp removes the bottles from the bottle holders and transfers them to the next station. Then the cycle repeats.
