Description

Technical Field

[0001] This utility model relates to the field of ampoule filling technology, specifically to an ampoule filling machine. Background Technology

[0002] With the continuous advancement of modern medicine, the research and development and production scale of various injectable drugs are expanding daily. Ampoules, as a commonly used packaging for injectable drugs, offer advantages such as good sealing, resistance to contamination, and ease of storage and transportation. To meet the demand for large-scale production of high-quality injectable drugs, ampoule filling and sealing machines have emerged.

[0003] Existing ampoule filling and sealing machines include a worktable, a bottle inlet mechanism, and a bottle outlet mechanism. During operation, the conveyor track in the bottle inlet mechanism pushes the bottle into the turntable, where the filling mechanism fills the bottle with liquid. After filling, the bottle rotates to the bottom of the sealing mechanism, where the bottle mouth is melted at high temperature by a sealing gun. Finally, the bottle mechanism transports and collects the bottles. During the filling process, due to the different viscosities of various liquids, needle blockage often occurs when filling liquids with higher viscosity. This requires repeated disassembly and unblocking of the needle. Since disassembly and assembly require the use of corresponding disassembly tools, the repetitive operation increases the time cost of disassembly and assembly, and the increased time of the disassembly and assembly process also makes the needles prone to contamination.

[0029] 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.

[0030] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.

[0031] Example 1

[0032] Please see Figure 1-5 This embodiment provides a technical solution for an ampoule filling machine: an ampoule filling machine is used to be set above a workbench 1. The ampoule filling machine includes a filling mechanism 2 and a needle mounting part 3. The filling mechanism 2 is fixedly connected above the workbench 1. The filling mechanism 2 includes a support rod 202 fixedly connected to the top of the workbench 1. The support rod 202 can provide load-bearing capacity. A filling rack 201 is fixedly connected to the side of the support rod 202 near the workbench 1.

[0033] The needle mounting part 3 is located below the filling frame 201. The needle mounting part 3 includes an infusion port 307 that is evenly distributed inside the filling frame 201. An external feed pump delivers liquid through a pipeline to the top of the infusion port 307. An installation block 308 is provided on the outside of the infusion port 307. Both ends of the installation block 308 are provided with installation grooves 309. A fixing block 302 is fixedly connected to the bottom end of the installation block 308. Connecting rods 304 are evenly distributed on both ends of the fixing block 302. A connecting spring 305 is sleeved on the outside of the connecting rod 304. A limit block 303 is slidably provided on the end of the connecting rod 304 away from the fixing block 302. Both ends of the connecting spring 305 are fixedly connected to the fixing block 302 and the limit block 303, respectively. Figure 4 As shown, when the connecting spring 305 is not under force, it uses its own elastic potential energy to push the limiting block 303 to move to the end of the connecting rod 304 away from the fixed block 302. The connecting spring 305 drives the limiting block 303 to move laterally.

[0034] The limiting block 303 is designed in an inverted L shape. There are two sets of the limiting block 303. The limiting blocks 303 are symmetrically distributed about the internal center point of the fixing block 302. The limiting blocks 303 fit into the interior of the mounting groove 309. The bottom end of the fixing block 302 is provided with a filling needle 301. The interior of the fixing block 302 is designed as a hollow structure. The interior of the fixing block 302 is connected to the interior of the filling needle 301, which can facilitate the flow of liquid. The top end of the fixing block 302 is provided with a sealing ring 306. The sealing ring 306 fits into the infusion port 307, which can improve the sealing performance of the filling needle 301 after installation. The diameter of the infusion port 307 is smaller than the inner diameter of the fixing block 302. The infusion port 307 is inserted into the interior of the fixing block 302, which can facilitate the installation of the filling needle 301.

[0035] Example 2

[0036] A transmission turntable mechanism 4 is installed in the middle of the top of the worktable 1. The working principle of the transmission turntable mechanism 4 is that the cam rotates under the action of power, and the special shape of its contour curve causes the follower to produce a specific motion law. If the follower and the turntable are connected by a suitable connection method (such as a connecting rod), the rotational motion of the cam will be converted into the intermittent rotation or oscillation of the turntable. This can realize the intermittent rotation of the turntable to transport the bottles on the turntable. When selecting it, the appropriate model should be selected according to the actual needs. The components required in the transmission turntable mechanism 4 are all existing technologies and will not be described in detail below.

[0037] One end of the transmission turntable mechanism 4 is equipped with a bottle feeding mechanism 6. The working principle of the bottle feeding mechanism 6 is that a motor drives the medicine bottles on the bottle feeding track to move forward at a specific speed through a reducer, sprocket chain, or gear transmission. For example, when the filling head of the filling station needs to perform a filling operation at regular intervals, the synchronous drive mechanism will ensure that the medicine bottles move at the corresponding speed, so that each medicine bottle arrives at the filling station in sync with the movement of the filling head, ensuring the accuracy and stability of filling. When selecting the appropriate model, the appropriate model should be selected according to the actual needs. The components required in the bottle feeding mechanism 6 are all existing technologies and will not be described in detail below.

[0038] A bottle dispensing mechanism 7 is located at the end of the transmission turntable mechanism 4 furthest from the bottle feeding mechanism 6. The bottle dispensing mechanism 7 includes a collection box for convenient collection of items discharged from the transmission turntable mechanism 4. A heat-melting mechanism 5 is located at the top of the worktable 1 near the bottle dispensing mechanism 7, with its output end positioned directly above the transmission turntable mechanism 4. The heat-melting mechanism 5 works by using a resistance wire or heating element to generate heat, which is then transferred to the neck of the ampoule. The heating element is typically made of high-temperature resistant materials, such as nickel-chromium alloy wire. When current passes through, the resistance wire generates heat, which is conducted to heat the neck of the ampoule to a melting state. When selecting the appropriate model, it should be chosen according to actual needs. All components required in the heat-melting mechanism 5 are existing technologies and will not be described in detail below.

[0039] Example 3

[0040] A first magnet block 310 is provided at the bottom of the mounting groove 309. A second magnet block 311 is provided above both ends of the limiting block 303. The second magnet block 311 is magnetically connected to the first magnet block 310. The magnetic poles of the second magnet block 311 and the first magnet block 310 are opposite. The elastic potential energy of the connecting spring 305 is used to push the limiting block 303 into the mounting groove 309. The magnetic connection between the first magnet block 310 and the second magnet block 311 can be used to fix the limiting block 303, which improves the stability of the filling needle 301 during operation.

[0041] Working principle: First, turn on the power. By pressing the limiting block 303, the limiting block 303 can be moved outside the connecting rod 304. The top of the limiting block 303 can be moved out of the mounting groove 309 inside the mounting block 308, which can separate the first magnet block 310 and the second magnet block 311. The fixing block 302 can be easily removed from below the infusion port 307, and the filling needle 301 can be quickly replaced, which improves the disassembly and assembly speed of the device.

[0042] Finally, during operation, the bottle body is pushed onto the turntable inside the transmission turntable mechanism 4 by the conveying track inside the bottle feeding mechanism 6. Then, the liquid is injected into the filling needle 301 by the feed pump. The filling needle 301 can be used to fill the bottle body. After filling, the bottle body rotates to the bottom of the hot melting mechanism 5. The bottle mouth is melted at high temperature by the heating mechanism inside the hot melting mechanism 5. Finally, the bottle feeding mechanism 6 transports and collects the bottles.
