Receiving and clamping device of filling machine packaging bag

Abstract

The present invention provides a receiving and clamping device of filling machine packaging bag. Edges of a rotating plate are uniformly distributed with clamping assemblies; a plurality of guide grooves which are uniformly distributed along the circumferential direction are arranged on the rotating plate near the edge; the circle center of the guide groove is superposed with the gyration center of the rotating plate; a shaft pin on a hook hinged on a base is penetrated into the guide groove; the base of the clamping assembly is hinged with a clamping arm; a spring is abutted against between the back end of the clamping arm and the back part of the base; lower part of the clamping arm is fixed with a baffle block; the rotating plate is fixed with a convex block aligned to the baffle block; the spring is connected with the base and the rotating plate; external side of the rotating plate is provided with a pusher dog matched with the hook; the external side of the rotating plate is provided with a cylinder fixed on a bracket; the pusher dog is hinged with a piston rod of the cylinder. The receiving and clamping device of filling machine packaging bag can exactly receive and clamp the packaging bag in the continuous running of the rotating plate, which avoids the frequent starting and stopping when the rotating plate works, ensures that the rotating plate always stably runs at even speed and greatly improves the production efficiency of the apparatus.

Description

technical field

[0001] The invention relates to a packaging bag clamping device on a filling machine, in particular to a receiving and clamping device for a packaging bag of a filling machine. Background technique

[0002] At present, all kinds of wide-mouth forming bag supply bag filling machines on the market basically adopt the method of multi-station rotary packaging on a circular turntable. The basic structural mode required by this method is that the There are several clamping devices, and a bag feeding mechanism is provided on the outside of the circular turntable, and the bags are sent to each clamping device through the bag feeding mechanism to realize the packaging of the product. The clamping device of the existing forming bag filling machine for bags is fixed on the turntable. In order to realize the requirements of the bag feeding mechanism for feeding bags to each station on the turntable, the turntable adopts a step-by-step rotation method, so that When the t...
