Technical Field

[0001] This utility model relates to the field of pharmaceutical production technology, specifically to a liquid pharmaceutical filling machine. Background Technology

[0002] With the improvement of living standards, people have higher requirements for their health, leading to an increase in the demand for liquid medicines. Liquid medicine filling is divided into manual filling and mechanical filling. Mechanized filling not only improves labor productivity, reduces product loss, and ensures packaging quality, but also reduces cross-contamination between the production environment and the materials being filled. Therefore, modern liquid medicine manufacturing enterprises generally use a liquid medicine filling machine.

[0003] Regarding the aforementioned technologies, the applicant believes that when a liquid medicine filling machine is in operation, by placing the medicine bottle in a fixed slot on a rotating disk and using a drive motor to rotate the rotating disk, the medicine bottle can be rotated accordingly. This allows the medicine bottle to be moved below the filling head. By opening the control valve outside the infusion tube, the liquid medicine can be easily injected into the medicine bottle. However, when the device fills medicine bottles of different sizes, the different heights of the different sizes of medicine bottles result in a significant gap difference between the filling head and the bottle mouth, causing the liquid medicine to leak. This not only wastes the medicine but also contaminates the rotating disk and the surface of the equipment, increasing cleaning costs and seriously affecting the practicality of the device and production compliance.

[0024] 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.

[0025] Example 1: Please refer to Figures 1 to 4 This embodiment provides a technical solution: a liquid medicine filling machine, including a base 3 and a filling mechanism 1. The filling mechanism 1 is disposed on one side of the base 3. The filling mechanism 1 includes a support frame 101 disposed on one side of the base 3. A medicine tank 103 is disposed at the top of the support frame 101. The support frame 101 and the medicine tank 103 form a welded integrated structure, which can improve the stability of the medicine tank 103 during operation.

[0026] A fixing rod 108 is installed at one end of the bottom of the medicine tank 103. A drive motor 109 is installed at the top of the inside of the fixing rod 108. The drive motor 109 operates based on the principle of electromagnetic induction. When three-phase alternating current is applied to the stator windings, a rotating magnetic field is generated within the stator core. Its rotational speed is determined by the power supply frequency and the number of pole pairs of the motor. The rotor conductors cut magnetic lines of force in the rotating magnetic field, generating an induced current. The interaction between the current and the magnetic field produces electromagnetic torque, driving the rotor to rotate. When selecting the appropriate model, it should be chosen according to actual needs. All components required within the drive motor 109 are existing technologies and will not be described further below.

[0027] The output end of the drive motor 109 is provided with a lead screw 110, and the outside of the lead screw 110 is provided with a nut 111. The bottom end of the nut 111 is provided with a movable rod 107, and the bottom end of the movable rod 107 is provided with a connecting rod 106. The end of the connecting rod 106 away from the movable rod 107 is provided with a fixed seat 105. The inside of the fixed seat 105 is provided with a filling head 112, and the top end of the filling head 112 is provided with an infusion tube 113. The end of the infusion tube 113 away from the filling head 112 is connected to the medicine tank 103. A control valve is provided on the infusion tube 113. By opening the electromagnetic control valve outside the infusion tube 113, the liquid medicine in the medicine tank 103 can be injected into the medicine bottle through the filling head 112.

[0028] The top of the medicine tank 103 is provided with a liquid filling port 102. The inside of the liquid filling port 102 is provided with a sealing gasket to minimize the possibility of external impurities falling into the medicine tank 103 through the liquid filling port 102. The fixed rod 108 and the movable rod 107 are both hollow structures. The movable rod 107 is inserted into the inside of the fixed rod 108.

[0029] The overall effect of Embodiment 1 is as follows: When the device fills medicine bottles of different sizes, the drive motor 109 is started by the control switch, which drives the lead screw 110 to rotate around the axis. The ball nut 111 adapted to the outside of the lead screw 110 converts the rotational motion of the lead screw 110 into linear motion along the axis of the lead screw 110. The movable rod 107, which is fixedly connected to the nut 111, moves up and down synchronously with the nut 111. Through the transmission of the connecting rod 106, the fixed seat 105 and the internal filling head 112 are driven to achieve height adjustment, making it convenient for the device to fill medicine bottles of different heights and improving the practicality of the device.

[0030] Example 2: A sliding rod 104 is provided at the bottom end of the medicine tank 103 away from the fixed rod 108, and the fixed seat 105 is slidably disposed outside the sliding rod 104. The effect achieved by the entire second embodiment is that it can easily support the fixed base 105 and improve the stability of the fixed base 105 when it moves up and down.

[0031] Example 3: A rotating disk 6 is rotatably installed at the top of the base 3. A servo motor is installed inside the base 3. The output end of the servo motor is connected to the rotating shaft inside the rotating disk 6. Fixed grooves 4 are evenly opened around the rotating disk 6. Anti-slip pads 5 are installed inside the fixed grooves 4. The anti-slip pads 5 are made of silicone. A protective railing 2 is installed on the outside of the top of the base 3 to facilitate the protection of the medicine bottle.

[0032] The effect achieved by the entire embodiment 3 is as follows: the servo motor inside the base 3 drives the rotating disk 6 to rotate, so that the medicine bottle is synchronously moved to the bottom of the filling head 112 along with the rotating disk 6.

[0033] Working principle: When the device is working, the operator places the medicine bottle into the silicone anti-slip pads 5 built into the fixed grooves 4 distributed around the circumference of the rotating disk 6. The servo motor inside the base 3 drives the rotating disk 6 to rotate, so that the medicine bottle is synchronously moved with the rotating disk 6 to directly below the filling head 112. Then the rotating disk 6 stops rotating, completing the alignment. Then, by opening the electromagnetic control valve on the outside of the infusion tube 113, the liquid medicine in the medicine tank 103 can be injected into the medicine bottle through the filling head 112. Secondly, when the device fills medicine bottles of different sizes, the drive motor 109 is started by the control switch, which drives the lead screw 110 to rotate around the axis. The ball nut 111 adapted to the outside of the lead screw 110 converts the rotational motion of the lead screw 110 into linear motion along the axis of the lead screw 110. The movable rod 107, which is fixedly connected to the nut 111, moves up and down synchronously with the nut 111. Through the transmission of the connecting rod 106, the fixed seat 105 and the internal filling head 112 are driven to achieve height adjustment, making it convenient for the device to fill medicine bottles of different heights and improving the practicality of the device.
