Description

Technical Field

[0001] This utility model relates to the field of plastic bottle cap processing technology, and in particular to an automatic punching machine for plastic bottle caps. Background Technology

[0002] Bottle caps are essential components of various packaging containers, serving to keep the contents of the product sealed, as well as providing anti-theft and security features. They are widely used in the food, beverage, daily chemical, and pharmaceutical industries.

[0003] To improve user convenience, some push-button bottle caps can be directly used as dispensing channels (such as pump caps for hand sanitizer and laundry detergent bottles), while others are used for dispensing control (such as condiment bottle caps). Some children's beverage bottles and sports water bottles have caps that can accommodate straws or connect tubing for easy drinking. All of these applications require holes in the bottle cap. There are several methods for creating these holes. The mainstream method is to punch the hole in the mold during injection molding, but the hole diameter is limited by the mold. Another method is to punch the hole using a stamping machine, but this requires manual loading and unloading, manual operation of the stamping machine, lower processing efficiency, and the stamping process can easily produce burrs and damage the bottle cap due to the high pressure.

Detailed Implementation

[0026] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0027] like Figure 1-3 As shown: An automatic punching machine for plastic bottle caps includes: a worktable 1, a plastic bottle cap base 2 for supporting plastic bottles disposed on the worktable 1, a set of transfer manipulators 3 rotatably disposed on the worktable 1 for loading and unloading materials, and a punching mechanism 4 disposed on the worktable 1 for vertical punching operation.

[0028] The punching mechanism 4 is located directly above the plastic bottle cap base 2, and the side of the plastic bottle cap base 2 is provided with a clamping mechanism 5 for clamping the plastic bottle cap.

[0029] Among them, such as Figure 4-5 As shown, the plastic bottle base 2 has a bottle cap placement hole 21 at its center, and a punching boss 22 at its center. The bottle cap placement hole 21 and the punching boss 22 form an annular placement cavity. A photoelectric sensor is located at the bottom of the placement cavity. The punching boss 22 has a punching hole 23 at its center. The plastic bottle base 2 also has a waste hole 24 communicating with the punching hole 23. The worktable 1 has a hole communicating with the waste hole 24. The side of the plastic bottle cap is held in the placement cavity, and its top surface contacts the surface of the punching boss 22 to provide support. The waste generated after punching falls from the bottom of the worktable through the waste hole 24.

[0030] Specifically, the plastic bottle base 2 has a positioning groove 25 on its side, and a rectangular through groove 26 communicating with the bottle cap placement hole 21 is provided on the positioning groove 25. Guide posts 27 are provided on both sides of the positioning groove 25.

[0031] The clamping mechanism 5 includes a clamping cylinder 51 and a T-shaped drive block 52 connected to the clamping cylinder 51. The T-shaped drive block 52 has a rectangular clamping block 53, which can slide within a rectangular through slot 26. Both sides of the T-shaped drive block 52 are slidably connected to guide posts 27. The protruding portion of the T-shaped drive block 52 can engage with a positioning groove 25. When the T-shaped drive block 52 moves, it engages with the positioning groove 25 to provide guidance and limit movement. Simultaneously, the guide rod 27 also guides the T-shaped drive block 52, improving its movement accuracy.

[0032] like Figure 6 As shown, the transfer manipulator 3 is mounted on the workbench 1 via a bracket 31. The transfer manipulator 3 includes a rotary cylinder 32, a cantilever 33 mounted on the rotary cylinder 32, and a cylinder 34 mounted at the end of the cantilever 33. The actuating end of the cylinder 34 is provided with a pneumatic gripper 35 for gripping plastic bottle caps.

[0033] Furthermore, the punching mechanism 4 includes a mounting bracket 41 erected above the plastic bottle cap base 2, and a punching cylinder 42 mounted on the mounting bracket 41. The actuating end of the punching cylinder 42 passes through the mounting bracket 41 and has a punching portion 43. The punching diameter of the punching portion 43 is equal to the diameter of the punching hole 23. Because the diameter of the punching portion 43 matches that of the punching hole 23, the punching portion passes precisely through the bottle cap along the punching hole 23 during punching, effectively reducing burrs. Simultaneously, the bottle cap is protected from deformation and damage during punching by the support of the punching boss 22.

[0034] Specifically, the transfer robot 3 is provided with a feeding belt 11 and a discharging belt 12 on both sides for conveying plastic bottle caps.

[0035] Preferably, the workbench 1 is further provided with a control panel 14 for adjusting punching parameters, and the control panel 14 is provided with a display screen.

[0036] The working principle of the automatic punching machine for plastic bottle caps provided by this utility model is as follows:

[0037] After the transfer robot 3 picks up a plastic bottle cap from the feeding belt 11, it places it into the bottle cap placement hole 21. Once the photoelectric sensor detects the bottle cap, the clamping cylinder 51 drives the rectangular clamping block 53 to clamp the bottle cap from four directions. After the clamping cylinder 51 reaches its position, the punching cylinder 42 drives the punching part 43 to move downwards and act on the bottle cap to complete the punching. After the punching cylinder 42 resets, the clamping cylinder 51 drives the rectangular clamping block 53 to retract and release the bottle cap. Then, the transfer robot 3 picks it up and removes it from the production line. Simultaneously, when the photoelectric sensor no longer detects a bottle cap, the transfer robot 3 picks up another bottle cap from the feeding belt 11 for punching. This process is highly efficient and achieves automated operation.

[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
