Description

Technical Field

[0001] This utility model relates to the technical field of plastic bottle cap production equipment, specifically a ring cutting device for the production and processing of pharmaceutical plastic bottle caps. Background Technology

[0002] In the production and processing of pharmaceutical plastic bottle caps, the ring-cutting process is one of the key steps. Its function is to cut a ring-shaped structure at a specific location on the bottle cap to meet the requirements of sealing or opening. Traditional ring-cutting usually uses a fixed cutter or a continuous rotary cutting method, where the bottle cap is manually or robotically fed to the processing station and then cut by the cutter. However, as the pharmaceutical industry's requirements for bottle cap production efficiency and precision continue to increase, traditional processing methods have gradually revealed certain problems that need to be improved.

[0003] In existing ring-cutting devices, the continuous rotary cutting method can easily lead to excessive contact time between the blade and the bottle cap, resulting in burrs or uneven ring cutting, which affects product quality. Furthermore, when processing bottle caps of different specifications, it is often necessary to change tooling or adjust the mechanical structure, which is not flexible enough to meet the needs of multi-variety, small-batch production. Utility Model Content

[0004] The purpose of this invention is to provide a cutting ring device for the production and processing of pharmaceutical plastic bottle caps. By setting an intermittent component, the intermittent radial feed motion of the cutter holder is realized, which solves the problem of long contact time between continuous cutting and bottle cap.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model relates to a ring-cutting device for the production and processing of pharmaceutical plastic bottle caps, comprising a frame and an intermittent assembly. An L-shaped plate is mounted on the top of the frame, and a knife holder is provided on the L-shaped plate. The intermittent assembly has a connecting rod, a first rotating shaft, and a cam. The first rotating shaft is fitted onto the bottom plate of the L-shaped plate, and a through hole is provided on the L-shaped plate. The connecting rod is slidably fitted into the through hole. The cam is sleeved on the top end of the first rotating shaft, and the outer surface of the cam contacts the end of the connecting rod. The other end of the connecting rod is connected to the outer surface of the knife holder.

[0007] Furthermore, a spring connects the outer surface of the L-shaped plate to the tool holder.

[0008] Furthermore, the frame has a through hole, a second rotating shaft is fitted inside the through hole, and a turntable is mounted on the second rotating shaft.

[0009] Furthermore, a positioning post is installed on the top of the turntable, and a rubber ring is provided on the positioning post.

[0010] Furthermore, a top plate is installed on the top of the frame, and an electric push rod is installed on the top plate. A floating pressure head is installed at the output end of the electric push rod, and the top plate corresponds to the position of the positioning column.

[0011] Furthermore, the tool holder has a frame, a motor, and a cutting blade. The motor is installed inside the frame, and the cutting blade is installed at the output end of the frame.

[0012] This utility model has the following beneficial effects:

[0013] This invention achieves intermittent radial feed motion of the tool holder through the cooperation of a cam and a connecting rod, making the cutting action precise and controllable. It avoids the problems of burrs or uneven cutting rings caused by traditional continuous rotary cutting methods. After the cam pushes the connecting rod to drive the tool holder to complete the cutting, the spring automatically resets the tool holder, which simplifies the mechanical structure, reduces the equipment manufacturing cost and maintenance difficulty, and improves the stability and consistency of cutting.

[0014] This invention achieves automatic positioning and stable clamping of bottle caps through a structure design that combines a turntable with a positioning column and a floating pressure head. By adjusting the cam profile or the tool holder stroke, it can be adapted to process bottle caps of different specifications, making the equipment more adaptable to production. It can meet the production needs of multiple varieties and small batches, significantly improving production efficiency and product quality, and providing an efficient and reliable solution for the processing of pharmaceutical plastic bottle caps.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a ring-cutting device for the production and processing of pharmaceutical plastic bottle caps, including a frame 1 and an intermittent assembly. An L-shaped plate 2 is installed on the top of the frame 1. A spring 7 is connected between the outer surface of the L-shaped plate 2 and the blade holder 4. After cutting, the spring 7 pulls the blade holder 4 back to its original position, causing the cutting blade 403 to detach from the bottle cap, ready for the next feed. The blade holder 4 is provided on the L-shaped plate 2. The intermittent assembly has a connecting rod 3, a first rotating shaft 5, and a cam 6. A stop block 301 is installed at the end of the connecting rod 3 to prevent the connecting rod 3 from moving too far. The first rotating shaft 5 is externally connected to a drive source and is fitted onto the bottom plate of the L-shaped plate 2. A through hole 201 is provided on the L-shaped plate 2. The connecting rod 3 is slidably fitted into the through hole 201. The cam 6 is sleeved on the L-shaped plate 2. At the top of the first rotating shaft 5, the outer surface of the cam 6 contacts the end of the connecting rod 3. The other end of the connecting rod 3 is connected to the outer surface of the tool holder 4. When the first rotating shaft 5 drives the cam 6 to rotate, the contour of the cam 6 pushes the connecting rod 3 to slide along the through hole 201, thereby driving the tool holder 4 to feed radially towards the bottle cap. When cutting the plastic bottle cap ring, the first rotating shaft 5 is driven by the drive source, which drives the cam 6 to rotate. When the protruding part of the cam 6 contacts the connecting rod 3, it pushes the connecting rod 3 to slide along the through hole 201, causing the tool holder 4 to feed radially towards the bottle cap. The cutting blade 403 rotates at high speed under the drive of the motor 402 to complete the ring cutting process. When the cam 6 continues to rotate to the concave part, the spring 7 pulls the tool holder 4 to reset, and the cutting blade 403 exits the bottle cap to avoid over-cutting.

[0023] The frame 1 has a through hole, and a second rotating shaft 8 fits inside the through hole. The second rotating shaft 8 is externally connected to a drive source. A turntable 9 is installed on the second rotating shaft 8. A positioning post 10 is installed on the top of the turntable 9. A rubber ring 11 is set on the positioning post 10 to fix the bottle cap to be cut. A top plate 12 is installed on the top of the frame 1. An electric push rod 13 is set on the top plate 12. A floating pressure head 14 is installed at the output end of the electric push rod 13. The top plate 12 corresponds to the position of the positioning post 10. During operation, the bottle cap is automatically transported to the positioning post 10 of the turntable 9 by a vibrating plate (not shown in the figure) and is initially fixed by the rubber ring 11. Then the electric push rod 13 is started to push the floating pressure head 14 down to make the bottle cap stable on the turntable 9. At the same time, the second rotating shaft 8 drives the turntable 9 to rotate, so that the bottle cap rotates to cooperate with the cutting station to cut the ring.

[0024] The tool holder 4 has a frame 401, a motor 402 and a cutting blade 403. The motor 402 is installed inside the frame 401. The cutting blade 403 is installed at the output end of the frame 401. The frame 401 is pushed to the bottle cap by the connecting rod 3. The cutting blade 403 rotates at high speed under the drive of the motor 402 to complete the ring cutting process.
