Description

Technical Field

[0001] The utility model relates to the technical field of filling machines, in particular to a liquid filling machine for medical injections. Background Art

[0002] A filling machine is a mechanical device used to fill liquid, powder or granular materials into containers. In the case of large-scale production of injections, the use of liquid filling machines can achieve efficient automated production. This machine can automatically fill pre-prepared medical injections into vials or bags and complete the sealing and packaging process, improving production efficiency and consistency.

[0003] After searching, the Chinese patent document announcement number: CN214653565U discloses a Qingkailing injection filling machine, including a support component, a transmission component is installed on the top of the support component, a filling component is fixedly connected to the right side of the top of the support component, and an ultraviolet lamp is arranged at the lower end of the top of the support component. The transmission component includes a fixed block, a conveyor belt, a placement seat and a placement slot. The utility model starts the electric telescopic rods at both ends to drive the clamping block to fix the filling bottle to prevent the filling bottle from tipping over during the filling process, resulting in filling failure. When the filling head is pressed down to fill the injection bottle, when the pressure at the filling bottle mouth is too large or the force is uneven, the spring will elastically deform and retract downward, thereby reducing the pressure on the bottle mouth, preventing the filling bottle mouth from being damaged, and improving the work efficiency of filling the injection liquid. The liquid outlet of the filling head is sealed by the cover plate, which can prevent the injection liquid from overflowing when the filling head is filling the liquid, causing the waste of injection liquid and reducing economic losses.

[0004] The beneficial effects of the above patent specification mention that "the electric telescopic rods at both ends are started to drive the clamping blocks to fix the filling bottle to prevent the filling bottle from tipping over during the filling process, resulting in filling failure. When the filling head is pressed down to fill the injection bottle, when the pressure at the filling bottle mouth is too large or the force is uneven, the spring will elastically deform and retract downward, thereby reducing the pressure on the bottle mouth, preventing damage to the filling bottle mouth, and improving the work efficiency of filling injection liquid."
