Description

Technical Field

[0001] This utility model belongs to the field of tightening mechanism technology, specifically relating to a medicine bottle cap tightening mechanism. Background Technology

[0002] The most common caps used for medicine bottles are ordinary threaded caps. These caps have anti-slip grooves on their outer walls. Tightening the cap is an important step in ensuring the airtightness and safety of the medicine.

[0003] In practice, operators manually screw the cap onto the bottle body, which is not only inefficient but also prone to situations where the cap is not fully tightened, making the bottle prone to leakage during transportation due to compression. Utility Model Content

[0004] (1) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a medicine bottle cap tightening mechanism. This medicine bottle cap tightening mechanism aims to solve the technical problems of the existing technology, which is not only inefficient, but also prone to the situation where the bottle cap is not fully tightened to the bottle body.

[0006] (2) Technical solution

[0007] To solve the above-mentioned technical problems, this utility model provides a medicine bottle cap tightening mechanism, including a support frame and a lifting frame disposed on the inner wall of the support frame. A fixed cylinder is installed at the bottom end of the lifting frame, and a tightening rod is rotatably inserted into the fixed cylinder through a bearing. A servo motor for driving the tightening rod to rotate is fixed at the top end of the lifting frame. A base is fixed at the bottom end of the support frame, and a positioning seat is fixed at the top end of the base. The medicine bottle body is embedded in the positioning seat.

[0008] When using this technical solution, a lifting frame is slidably installed on one side of the support frame. During installation, the bottle cap body is inserted into the groove to fit snugly, and the medicine bottle body is inserted into the axial positioning groove to fit snugly. The hydraulic rod and servo motor are activated. The hydraulic rod drives the lifting frame to move downward, while the servo motor drives the bottle cap body to rotate. After the bottle cap body contacts the top of the medicine bottle body, it is tightened. After tightening, the servo motor is turned off, and the hydraulic rod drives the lifting frame and servo motor to return to their original position. This facilitates automatic tightening of the bottle cap body and avoids the situation where the bottle cap and the bottle body are not completely tightened. By setting a fixed cylinder that is fixed to the lifting frame, the fixed cylinder positions and protects the tightening rod, keeping the tightening rod in a vertical state at all times. This reduces the possibility of the tightening rod bending over time, which could cause errors between the bottle cap and the medicine bottle. At the same time, the slider fits into the slide rail and slides within the slide rail, allowing the lifting frame to move in a vertical direction, thus improving the vertical linear movement of the lifting frame and the tightening rod.

[0009] Preferably, the lifting frame has an L-shaped structure, and a hydraulic rod connected to the lifting frame is fixedly installed at the top of the support frame.

[0010] Furthermore, the inner wall of the support frame is fixed with a slide rail, and the lifting frame is fixed with a slider that is slidably engaged with the slide rail. The slide rail is embedded with a hexagonal socket head cap screw that is threaded into the support frame, and the side wall of the lifting frame is embedded with a hexagonal socket head cap screw that is threaded into the slider.

[0011] Furthermore, the top of the tightening rod is provided with a connecting groove for accommodating the servo motor shaft, and the bottom of the tightening rod is provided with a groove. A connector that fits into the connecting groove is fixed on the servo motor shaft, and the connector at the bottom of the servo motor is axially positioned with the inner wall of the connecting groove. The bottle cap body is kept stable in the groove by friction with the inner wall of the groove. The friction can withstand the slight weight of the bottle cap body and will not fall out of the groove.

[0012] Furthermore, a bottle cap body is provided on the top of the main body of the medicine bottle, and the bottle cap body is damped and inserted into the groove. The inner wall of the groove is provided with a protrusion that fits into the anti-slip groove on the outer wall of the bottle cap body.

[0013] Furthermore, the top of the positioning seat is provided with an axial positioning groove in the shape of a square. The main body of the medicine bottle is in the shape of a square and fits into the axial positioning groove. Both ends of the positioning seat are provided with bolts threaded into the base. After unscrewing the bolts, the positioning seat with a different shape of axial positioning groove can be replaced, which is suitable for tightening the cap of different types of medicine bottle bodies.

[0014] Furthermore, the top of the positioning seat is provided with an axial positioning groove in the shape of a rectangle, and the main body of the medicine bottle is in the shape of a rectangle and fits into the axial positioning groove.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This utility model features a lifting frame that slides on one side of a support frame. When installing the bottle cap body, it fits into the groove, and the medicine bottle body fits into the axial positioning groove. The hydraulic rod and servo motor are activated. The hydraulic rod drives the lifting frame to move downward, while the servo motor drives the bottle cap body to rotate. After the bottle cap body contacts the top of the medicine bottle body, it is tightened. After tightening, the servo motor is turned off, and the hydraulic rod drives the lifting frame and servo motor to return to their original positions. This facilitates automatic tightening of the bottle cap body and avoids the situation where the bottle cap and bottle body are not completely tightened.

[0018] By setting a fixed cylinder that is fixed to the lifting frame, the fixed cylinder positions and protects the tightening rod, keeping the tightening rod in a vertical state at all times. This reduces the possibility of the tightening rod bending after long-term use, which could cause errors between the bottle cap and the medicine bottle. At the same time, the slider fits into the slide rail and slides within the slide rail, allowing the lifting frame to move in a vertical direction, thus improving the vertical linear movement of the lifting frame and the tightening rod.

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.

[0026] This specific embodiment is a medicine bottle cap tightening mechanism, the structural diagram of which is shown below. Figure 1 and Figure 2As shown, it includes a support frame 1 and a lifting frame 2 installed on the inner wall of the support frame 1. A fixed cylinder 5 is installed at the bottom end of the lifting frame 2. A tightening rod 14 is rotatably inserted into the fixed cylinder 5 through a bearing. A servo motor 4 for driving the tightening rod 14 to rotate is fixed at the top end of the lifting frame 2. A base 9 is fixed at the bottom end of the support frame 1. A positioning seat 8 is fixed at the top end of the base 9. A medicine bottle body 7 is embedded in the positioning seat 8.

[0027] The lifting frame 2 has an L-shaped structure. A hydraulic rod 3 connected to the lifting frame 2 is fixedly installed at the top of the support frame 1. A slide rail 11 is fixed on the inner wall of the support frame 1. A slider 12 is fixed on the lifting frame 2 and slidably engaged with the slide rail 11. A hexagon socket head cap screw threaded into the support frame 1 is embedded in the slide rail 11. A hexagon socket head cap screw threaded into the slider 12 is embedded in the side wall of the lifting frame 2. A connecting groove 13 for accommodating the shaft of the servo motor 4 is opened at the top of the tightening rod 14, and a groove 15 is opened at the bottom of the tightening rod 14. A connector that fits into the connecting groove 13 is fixed on the shaft of the servo motor 4, and a connector at the bottom of the servo motor 4 is also fixed. The bottle cap body 6 is axially positioned with respect to the inner wall of the connecting groove 13. It remains stable in the groove 15 by relying on the friction between the bottle cap body 6 and the inner wall of the groove 15. The friction can withstand the slight weight of the bottle cap body 6 and will not fall out of the groove 15. When installing the bottle cap body 6, it fits into the groove 15 and the medicine bottle body 7 fits into the axial positioning groove 10. The hydraulic rod 3 and the servo motor 4 are started. The hydraulic rod 3 drives the lifting frame 2 to move downward. At the same time, the servo motor 4 drives the bottle cap body 6 to rotate. After the bottle cap body 6 contacts the top of the medicine body, it is tightened. After tightening, the servo motor 4 is turned off. The hydraulic rod 3 drives the lifting frame 2 and the servo motor 4 to return to the starting position.

[0028] like Figure 3 and Figure 4 As shown, a bottle cap body 6 is positioned above the main body 7 of the medicine bottle. The bottle cap body 6 is damped and inserted into a groove 15. The inner wall of the groove 15 has a protrusion that fits into the anti-slip groove on the outer wall of the bottle cap body 6. The top of the positioning seat 8 has an axial positioning groove 10 with a square structure. The main body 7 of the medicine bottle is fitted into the axial positioning groove 10 with a square structure. Bolts with threads inserted into the base 9 are provided at both ends of the positioning seat 8. After unscrewing the bolts, the positioning seat 8 with a different shape of axial positioning groove 10 can be replaced, which is suitable for different... The cap of the medicine bottle body 7 is tightened. The top of the positioning seat 8 is provided with an axial positioning groove 10 with a rectangular structure. The medicine bottle body 7 is inserted into the axial positioning groove 10 with a rectangular structure. The fixing cylinder 5 positions and protects the tightening rod 14, so that the tightening rod 14 is always in a vertical state. This reduces the possibility of the tightening rod 14 bending after long-term use, which may cause errors between the cap and the medicine bottle. At the same time, the slider 12 is inserted into the slide rail 11 and slides in the slide rail 11, so that the lifting frame 2 moves in the vertical direction.
