Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary devices, specifically to an automatic screw cap opening device for medicine bottles. Background Technology

[0002] In the medical and pharmaceutical fields, opening medicine bottle caps is a common and important operation. Currently, opening medicine bottles mainly relies on traditional manual methods, which have many obvious shortcomings.

[0003] Traditional manual bottle opening relies entirely on the operator's hand strength and skill. In scenarios requiring a large number of bottles to be opened, such as hospital pharmacies dispensing medications during peak hours or pharmaceutical companies conducting product quality testing, manual opening is not only slow but also causes operator fatigue due to prolonged repetitive tasks, resulting in extremely low work efficiency. Each bottle takes time to open, and the task of opening a large number of bottles consumes a significant amount of the operator's time, severely limiting the overall efficiency of the workflow.

[0004] Existing bottle opening tools have significant limitations in terms of applicability and versatility. Most tools are designed for a single purpose, only suitable for opening bottle caps of specific materials, thicknesses, or sealing methods. For example, some tools may only work with softer plastic caps, failing to effectively open harder metal or composite caps; conversely, tools designed for hard caps may cause excessive damage to the bottle when handling soft caps. In practical applications, bottle caps come in a wide variety of materials and sealing methods, and single-function opening tools cannot meet diverse opening needs. This leads to frequent tool changes during the opening of different types of bottle caps, increasing operational complexity and time costs.

[0005] During manual opening, operators need to directly touch the bottle cap with their hands. For bottles containing corrosive or toxic drugs, direct contact with the cap poses a risk of cuts from the cap's edge, and the medication may also contaminate the hands, posing a potential threat to the operator's health. Therefore, an automatic screw-on opening device for medicine bottles is proposed. Utility Model Content

[0006] The purpose of this utility model is to address the problems raised in the existing background technology. To achieve the above-mentioned utility model objective, this utility model provides the following technical solution: an automatic capping and unsealing device for medicine bottles, including a capping device gripping arm and an elliptical fixing frame disposed above the capping device gripping arm. Motor-powered batteries are embedded in the round holes on both sides of the elliptical fixing frame. A capping and unsealing servo motor is installed on the top middle section of the elliptical fixing frame, and an electrical circuit connects the motor-powered battery and the capping and unsealing servo motor. The power output end of the capping and unsealing servo motor is rotatably connected to a motor rotating shaft, and the motor rotating shaft is perpendicular to the capping device gripping arm.

[0007] As a preferred technical solution of this utility model, the bottom of the motor rotating shaft is connected to the opening tool connecting plug, and the opening tool connecting plug is equipped with an opening connecting shaft.

[0008] As a preferred technical solution of this utility model, a cap-opening spring cutter is rotatably fixed below the cap-opening connecting shaft, and the tip of the cap-opening spring cutter is provided with a spring tip.

[0009] As a preferred technical solution of this utility model, a connecting ring is installed below the grip of the opening device, and a medicine bottle opening cap is fixed at the bottom of the connecting ring.

[0010] As a preferred technical solution of this utility model, the cap opening spring cutter can be disassembled, and a cylindrical cutter replacement rod is connected below the opening connecting shaft.

[0011] As a preferred technical solution of this utility model, the bottom rod of the cylindrical tool replacement insert is provided with a tool replacement insert cap, and a screw-cap cylindrical tool is installed below the tool replacement insert cap.

[0012] As a preferred technical solution of this utility model, the screw cap opening cylindrical cutter is located inside the medicine bottle opening cap.

[0013] As a preferred technical solution of this utility model, the bottom of the screw cap opening cylindrical cutter is fixed with a blade arc-shaped blade holder, and the cylindrical cutter blade is installed on the blade arc-shaped blade holder.

[0014] Compared with existing technologies, the advantages of this invention are as follows: This invention uses a cap-opening servo motor to provide power, which can quickly drive the cutter to rotate, achieving rapid opening of the medicine bottle cap. Compared with the traditional manual opening method, it greatly saves opening time and improves work efficiency, making it suitable for scenarios that require opening a large number of medicine bottles, such as hospital pharmacies and pharmaceutical companies.

[0015] This utility model's screw-on capping spring cutter is detachable and can be easily replaced with a screw-on capping cylindrical cutter depending on the material, thickness, and sealing method of the medicine bottle caps. For softer plastic caps, the screw-on capping spring cutter can be used for initial loosening; for harder metal or composite material caps, the screw-on capping cylindrical cutter can be used for deeper cutting and unscrewing operations, enhancing the applicability and versatility of the device.

[0016] This utility model features a spring-loaded tip on the cap-opening spring cutter. Upon contact with the bottle cap, the spring's elasticity provides cushioning, preventing excessive damage to the bottle. It can be used in scenarios where bottle integrity is critical. The curved blade holder and cylindrical blade at the bottom of the cap-opening cylindrical cutter allow for more forceful cutting and unscrewing of the cap, meeting the opening needs of different types of caps.

[0017] This utility model's opening device has a connecting ring installed below the grip, and the bottle opening cap is fixed to the bottom of the connecting ring. The bottle opening cap plays a positioning role during the opening process, ensuring that the blade accurately applies force to the bottle cap and preventing the blade from deviating from the cap and causing damage to the surrounding environment or personnel. At the same time, it can also, to some extent, prevent fragments from flying out during blade rotation, improving operational safety.

[0018] This invention utilizes a motor-driven blade for automatic unsealing, reducing the need for operators to directly handle the bottle caps and minimizing the risk of hand injuries from the cap edges or contamination by the medication. It is particularly suitable for handling bottles containing corrosive or toxic drugs. The motor-powered battery is installed in the round holes on both sides of the elliptical mounting bracket. This layout ensures the overall stability of the device and facilitates battery installation and replacement. Simultaneously, the electrical circuit connects the motor-powered battery and the cap-opening servo motor, ensuring stable power transmission and guaranteeing the normal operation of the device.

[0019] The motor shaft of this invention is vertically mounted on the grip of the opening device, and the power is stably transmitted to the tool through the opening tool connecting the cap and the opening connecting shaft. This vertical mounting and connection method reduces the loss in the power transmission process, improves the power transmission efficiency, and enables the tool to perform the cap opening operation more effectively.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0028] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely illustrates some embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model. It should be noted that, in the absence of conflict, the embodiments and features and technical solutions in the embodiments of this utility model can be combined with each other. It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] Example 1: An automatic capping and unsealing device for medicine bottles includes an unsealing device grip 1 and an elliptical fixing frame 2 disposed above the grip 1. Motor-powered batteries 3 are embedded in the round holes on both sides of the elliptical fixing frame 2. A capping and unsealing servo motor 4 is installed on the top middle section of the elliptical fixing frame 3, and an electrical circuit connects the motor-powered battery 3 and the capping and unsealing servo motor 4. The power output end of the capping and unsealing servo motor 4 is rotatably connected to a motor rotating shaft 5, and the motor rotating shaft 5 is perpendicular to the grip 1. An unsealing cutter connecting cap 6 is connected to the bottom of the motor rotating shaft 5, and an unsealing connecting shaft 7 is installed on the unsealing cutter connecting cap 6. A capping and unsealing spring cutter 8 is rotatably fixed below the unsealing connecting shaft 7, and the tip of the capping and unsealing spring cutter 8 is provided with a spring tip 9.

[0030] A connecting ring 10 is installed below the gripping arm 1 of the opening device, and a medicine bottle opening cap 11 is fixed to the bottom of the connecting ring 10. The screw-on opening spring cutter 8 is detachable, and a cylindrical cutter replacement insert 12 is connected below the opening connecting shaft 7. A cutter replacement insert cap 13 is provided on the bottom rod of the cylindrical cutter replacement insert 12, and a screw-on opening cylindrical cutter 14 is installed below the cutter replacement insert cap 13. The screw-on opening cylindrical cutter 14 is located inside the medicine bottle opening cap 11. A blade arc-shaped blade holder 15 is fixed to the bottom of the screw-on opening cylindrical cutter 14, and a cylindrical cutter blade 16 is installed on the blade arc-shaped blade holder 15.

[0031] The working principle of this automatic capping and unsealing device for medicine bottles is as follows: The motor-powered battery 3 is installed in the round holes on both sides of the elliptical fixing frame 2, and is connected to the capping and unsealing servo motor 4 through an electrical circuit, providing the necessary power for the motor to operate and ensuring normal operation. After receiving power, the capping and unsealing servo motor 4 starts to operate, and its power output drives the motor rotating shaft 5, which is rotatably connected to it, to rotate. Because the motor rotating shaft 5 is vertically mounted on the grip frame 1 of the unsealing device, this vertical mounting method ensures that the rotational power is stably and vertically transmitted downwards.

[0032] The bottom of the motor rotating shaft 5 is connected to the opening tool connecting cap 6, and the opening tool connecting cap 6 is equipped with an opening connecting shaft 7. When the motor rotating shaft 5 rotates, the rotational power is transmitted to the opening connecting shaft 7 through the opening tool connecting cap 6, thereby driving the tool associated with the opening connecting shaft 7 to rotate.

[0033] A cap-opening spring cutter 8 is rotatably fixed below the opening connecting shaft 7, and the tip of the cap-opening spring cutter 8 is equipped with a spring-loaded blade tip 9. When the device is working, the spring-loaded blade tip 9 can provide a certain buffer by utilizing the elasticity of the spring when contacting the medicine bottle cap, so as to avoid excessive damage to the medicine bottle. At the same time, as the opening connecting shaft 7 rotates, the spring-loaded blade tip 9 can perform preliminary cutting or loosening operations on the medicine bottle cap.

[0034] Below the opening connecting shaft 7, there is also a cylindrical cutter replacement insert 12. A cutter replacement insert cap 13 is provided on the bottom of the cylindrical cutter replacement insert 12, and a cap-opening cylindrical cutter 14 is installed below the cutter replacement insert cap 13. The cap-opening cylindrical cutter 14 is located inside the medicine bottle cap 11, and its bottom is fixed with a blade arc-shaped blade holder 15, on which a cylindrical cutter blade 16 is installed. As the opening connecting shaft 7 rotates, the cap-opening cylindrical cutter 14 also begins to rotate. The cylindrical cutter blade 16 further cuts and unscrews the medicine bottle cap, thereby achieving the opening of the medicine bottle cap.

[0035] The cap-opening spring cutter 8 is detachable, allowing users to choose whether to use it or replace it with the cap-opening cylindrical cutter 14, depending on the material, thickness, and sealing method of the bottle cap. When the cutter needs to be replaced, the connection between the opening connecting shaft 7 and the cylindrical cutter replacement rod 12 facilitates easy replacement to meet different opening requirements.

[0036] The opening device's grip 1 provides an easy-to-grip and operate part for the operator, facilitating control of the device's position and force. A connecting ring 10 is installed below the grip 1, and a medicine bottle opening cap 11 is fixed to the bottom of the connecting ring 10. The medicine bottle opening cap 11 serves a positioning and protection function, ensuring that the blade accurately applies force to the medicine bottle cap during the opening process, while also preventing the blade from damaging the surrounding environment.

[0037] The working process of the automatic capping and unsealing device for medicine bottles: The operator first checks whether the power supply battery 3 for the motor has sufficient power and ensures that the power line connection is normal so that the capping and unsealing servo motor 4 can receive power normally. At the same time, the operator checks whether the capping and unsealing spring cutter 8 or the capping and unsealing cylindrical cutter 14 is firmly installed and whether the cutter is sharp and undamaged.

[0038] Depending on the material, thickness, and sealing method of the medicine bottle cap, the choice between using a screw-on capping spring cutter 8 or a screw-on capping cylindrical cutter 14 is determined. If the medicine bottle cap is relatively soft or requires initial loosening, the screw-on capping spring cutter 8 can be selected; if the cap is relatively hard or requires deeper cutting and unscrewing, the screw-on capping cylindrical cutter 14 should be used instead. When changing the cutter, disassembly and installation are conveniently achieved through the connection structure between the opening connecting shaft 7 and the cylindrical cutter replacement insert 12.

[0039] The operator holds the opening device and grips the handle 1, aligning the medicine bottle opening cap 11 with the medicine bottle cap that needs to be opened, so that the screw cap opening spring cutter 8 or the screw cap opening cylindrical cutter 14 is accurately positioned above the medicine bottle cap, ensuring that the relative position of the device and the medicine bottle is correct.

[0040] The cap-opening servo motor 4 is activated, and the motor power supply battery 3 provides power to the motor through the electrical circuit, causing the cap-opening servo motor 4 to start running. The power output of the motor drives the motor rotating shaft 5 to rotate. Since the motor rotating shaft 5 is vertically mounted on the grip frame 1 of the opening device, the rotational power is stable and transmitted vertically downward.

[0041] If the cap-opening spring cutter 8 is used, as the motor shaft 5 rotates, the power is transmitted to the opening connecting shaft 7 through the opening cutter connecting cap 6, which in turn drives the cap-opening spring cutter 8 to rotate. The spring-loaded blade tip 9 contacts the medicine bottle cap, using the elasticity of the spring to provide a certain buffer to avoid excessive damage to the medicine bottle, while performing a preliminary cutting or loosening operation on the medicine bottle cap.

[0042] Using a screw-on capping cylindrical cutter: If a screw-on capping cylindrical cutter 14 is used, the rotational power is also transmitted to the cylindrical cutter replacement rod 12 through the capping cutter connecting cap 6 and the capping connecting shaft 7, causing the screw-on capping cylindrical cutter 14 to start rotating. The cylindrical cutter blade 16, located on the blade arc-shaped blade holder 15, further cuts and unscrews the medicine bottle cap. As the cutter continues to rotate, the medicine bottle cap is gradually opened.

[0043] During the unsealing process, the operator controls the force applied to the bottle cap by holding the unsealing device's grip handle 1, ensuring that the blade can effectively cut and unscrew the cap while avoiding damage to the bottle due to excessive force. The operator adjusts the operating force and the device's position as needed based on the progress of the cap opening.

[0044] Once the bottle cap is fully opened, the operator shuts off the cap-opening servo motor 4, stops the rotation of the motor shaft 5, and the cutter also stops rotating.

[0045] Remove the bottle cap 11 from the bottle to complete the opening operation. Clean the device, removing any remaining cap fragments or debris from the blades. If necessary, store the device for future use. Also, depending on the battery level, consider charging the motor-powered battery 3.
