Full-automatic bag-feeding type packaging machine

Abstract

The invention discloses a full-automatic bag-feeding type packaging machine, comprising a rotating disc (13), a large cam (14), a bag feeding device (1), a marking device (2), a bag opening device (3), a material charging device (5), a heat-sealing device (6), a bag discharging device (7) and a bag bracing device (4). A bag clamping device (39) is arranged at the edges of the rotating disc (13); the bag feeding device (1), the marking device (2), the bag opening device (3), the material charging device (5), the heat-sealing device (6) and the bag discharging device (7) are all arranged outside the rotating disc (13); and the bag bracing device (5) is of a swing arm type and is movably mounted on the rotating disc (13). The packaging machine is characterized in that the bag feeding device (1), the bag opening device (3), the material charging device (5), the heat-sealing device (6) and the bag discharging device (7) are symmetrically arranged around the central point of the rotating disc (13); and the bag bracing device (4) is symmetrically arranged around the central point of the rotating disc (13). The full-automatic bag-feeding type packaging machine with the structure has the advantages of stable performance and high production efficiency.

Description

technical field [0001] The invention relates to a packaging machine which can automatically complete bag loading, coding, bag opening, feeding, heat sealing and bag unloading. Background technique [0002] At present, the number of food and chemical products packaged in composite film bags is increasing. When it first appeared, it was packaged by hand. In order to realize automatic packaging, those skilled in the art have just designed a kind of automatic packaging machine. Check the Chinese patent database, and get a patent No. 99204659.5, which is called a utility model patent for a multifunctional bag feeding packaging machine, which discloses the following content: a multifunctional bag feeding packaging machine, which is mainly composed of a bag feeding device, a bag clip The opening and closing device, the width device and the filling device are characterized in that: (1) the opening and closing device of the bag clip is composed of a cam, a rocker arm, a pull rod, a ...

AI Technical Summary

Problems solved by technology

This kind of stretching device must be of the blowing type, and cannot be stretched with a mechanical swing arm. If a mechanical swing arm is used, then when the bag is stretched, the two bags must also be stretched at the same time. open, but since there are two sets of working devices on the same station, two sets of this mechanical swing arm must also be used when supporting the bag, so that the two sets of mechanical swing arms can swing at the same station at the same time, When a swing arm is returning to its position, it will collide with the feeding hopper of the feeding device, making it impossible to return to its position, and the work of supporting the bag cannot be completed

Therefore, the material tape can only be stretched by blowing, and this blowing type stretching device, especially for thin film bags, the air nozzle itself of this blowing type stretching device It is not easy to align the bag mouth of the film bag, and after the bag is fed, the rotation of the turntable will easily cause the film bag to swing, so that the air nozzle of the blowing bag support device is even more difficult to align with the bag mouth, so that the bag cannot be supported. open, it will not be able to complete the following related processes
