Filling machine packaging bag follow-up sealing device

Abstract

The packing bag follow-up sealing device of the filling machine has a turntable and several clamping components. The clamping components are evenly distributed on the edge of the turntable. The sealing assembly corresponding to the clamping assembly on the turntable, the sliding seat is provided with a positioning assembly with a finger, the turntable has a blocking member that cooperates with the finger, and a proximity switch that is close to the front end of the sliding seat is fixed on the track. A spring is connected between the sliding seats. The invention has reasonable structure and reliable performance. The sealing components on the sliding seat can complete the sealing of the packaging bag in the process of following the rotation of the turntable, which avoids the frequent start and stop of the turntable when it is working, and ensures that the turntable can always run stably at a constant speed. , thereby greatly improving the production efficiency of the equipment; and the sealing components on the sliding seat cooperate accurately with the clamping components of the turntable, and the sealing effect of the packaging bag is good.

Description

technical field [0001] The invention relates to a packaging bag sealing device on a filling machine, in particular to a packaging bag sealing device on a forming bag filling machine. Background technique [0002] At present, a type of forming bag filling machine on the market basically uses a circular turntable multi-station rotary filling and packaging method. The basic structural mode of this method is that there are several Clamping device, each clamping device is equipped with a sealing device, and a bag feeding mechanism is provided on the outside of the circular turntable, and the bag is sent to each clamping device through the bag feeding mechanism, and the packaging bag is clamped by the clamping device and filled. After the packaging is completed, it is sealed by a sealing device. The sealing of the existing forming bag filling machine is sealed by the sealing device when the turntable rotates to the next station after the filling is completed. The structure of its...

AI Technical Summary

Problems solved by technology

The sealing of the existing forming bag filling machine is sealed by the sealing device when the turntable rotates to the next station after the filling is completed. The structure of its sealing device determines that the turntable adopts a step-by-step rotation method. So that when the turntable pauses, the sealing device finishes sealing, and the packaging bag falls freely, the bag feeding mechanism supplies bags to the clamping device, but the stepping turntable consumes a lot of effective time in the process of continuous start-stop-start , the working efficiency of the equipment is low, and the frequent start and stop of the turntable consumes a lot of power
