Description

Drip-proof device of viscous liquid filling machine and filling machine comprising drip-proof device

Technical Field

Background

In the field of food processing or medicine production, a filling machine for injecting liquid materials into a container is common equipment, and the injection time can be controlled by controlling the opening and closing of a discharge hole so as to achieve the purpose of filling. At present, in the working process of a liquid filling machine, residual liquid always leaks out of a discharge hole in an uncontrolled manner, so that the liquid is stuck on the outside of a working place or a packaging material, and the liquid is difficult to process.

In this way, the discharge port of the partial filling machine is additionally provided with a physically isolated valve, and when the filling machine is in a closed state, the valve is tightly closed to prevent internal liquid leakage, so that the partial filling machine has better sealing performance.

However, for viscous liquid, if the valve is closed for too long, the viscous liquid may adhere to the valve, and when the valve is opened, resistance is encountered, and even the viscous liquid may block the discharge port. Therefore, it is not appropriate to use a closed drip-proof device for these highly viscous liquids, and other handling methods are required.

At the same time, the movement of the third piston head 620 also provides for better cleaning of the discharge port 120, reducing the accumulation of residual filling liquid near the discharge port 120.

Unlike outer sleeve 300, inner sleeve 400 is fixedly coupled to discharge head 100, and specifically, the top of inner sleeve 400 is fixedly coupled to discharge head 100 (not shown). The inner sleeve 400 is shorter in length than the outer sleeve 300 and has a gap at the bottom of both so that the inner space of the outer sleeve 300 and the inner space of the inner sleeve 400 can communicate through the gap.

The first piston assembly 500 includes a first piston head 510 and a connecting rod 520, the first piston head 510 being annular and disposed between the outer sleeve 300 and the inner sleeve 400, with an outer side thereof being in abutment with an inner wall of the outer sleeve 300 and an inner side thereof being in abutment with an outer wall of the inner sleeve 400. The connecting rod 520 is connected at both ends to the first piston head 510 and the outfeed head 100, respectively, so that the first piston head 510 remains stationary with respect to the outfeed head 100.
