Abstract
Description
Technical Field
[0001] The utility model relates to a filling device, in particular to a sealed filling injection liquid filling device, belonging to the technical field of filling devices. Background Art
[0002] Injection refers to sterile solutions (including emulsions and suspensions) made of drugs for injection into the body, as well as sterile powders or concentrated solutions for preparation into solutions or suspensions before clinical use. Injection acts quickly and reliably, is not affected by pH, enzymes, food, etc., has no first-pass effect, can exert systemic or local positioning effects, and is suitable for patients who are not suitable for oral administration or cannot take oral medication. Injection is generally stored in a tank, so during production, a filling device is generally required to fill the sealing liquid.
[0003] However, most existing filling devices have various problems. For example, in the injection filling and sealing device disclosed in Publication No. CN218709096U, although it has the advantages of being able to move the bottle body horizontally when transporting empty bottles, making the bottle body more accurate when injecting the liquid medicine, and when injecting the liquid medicine, the injection needle is placed at the bottle mouth to prevent the liquid medicine from leaking out. When injecting the liquid medicine, the liquid medicine will push out the gas in the empty bottle and discharge it from the bottle body through the through hole, so that the bottle body will not be squeezed and ruptured by the gas. However, during filling, the pressure generated by the movement of the connecting rod piston is mostly used to press the injection fluid in the mother tank into the daughter tank. After one piston movement, the filled tank body needs to be removed and the next tank body to be filled needs to be placed on the bottom of the mother tank body before the next filling operation can be carried out. Such repeated operations are not only time-consuming and labor-intensive, but also cannot achieve streamlined operation, seriously affecting work efficiency. Utility Model Content

The mother tank body 2 is fixed to the top of the support frame 1, the piston connecting rod 3 is arranged on one side of the mother tank body 2 and passes through the support frame 1, the sub-tank body supporting tray 4 is rotatably connected to the top of the support frame 1 and is located on the bottom side of the mother tank body 2.

[0023] The linkage adjustment mechanism 5 includes a transmission rod 51, a transmission turntable 52, a limit rod 53 and an adjustment disk 54. The transmission rod 51 is rotatably connected to the support frame 1. The transmission turntable 52 is coaxially fixed to the bottom of the sub-tank support tray 4. The limit rods 53 are arranged at the edge of the transmission turntable 52 and are evenly spaced. The adjustment disk 54 is coaxially fixed to the transmission rod 51, and the edge of the adjustment disk 54 is clamped between two adjacent limit rods 53. The adjustment disk 54 has a spiral structure.
[0024] A servo motor 55 is also fixed in the support frame 1. The servo motor 55 is located on one side of the transmission rod 51, and one end of the transmission rod 51 is coaxially connected to the output shaft of the servo motor 55.
[0025] The piston pushing mechanism 6 includes a linkage cam 61, a supporting seat 62 and a linkage plate 63. The linkage cam 61 is fixed on the transmission rod 51 and is located on one side of the adjustment disk 54. The supporting seat 62 is fixed in the support frame 1. The linkage plate 63 is rotatably connected to the supporting seat 62, and one end of the linkage plate 63 slides and abuts against the edge of the linkage cam 61, and the other end slides and abuts against the telescopic part of the piston connecting rod 3.
[0026] In the present invention, a linkage adjustment mechanism 5 and a piston pushing mechanism 6 are provided, and the rotation of the transmission rod 51 drives the adjustment disk 54 to be linked, and the spiral structure in the adjustment disk 54 is linked in sequence between multiple limit rods 53, thereby driving the transmission turntable 52 to rotate, and the transmission turntable 52 drives the sub-tank support tray 4 to rotate.
