There are many types of screw packaging machines and many classification methods. There are many kinds from different viewpoints. According to the type of machinery, it is divided into: liquid screw packaging machine, powder screw packaging machine, granular screw packaging machine, body screw packaging machine, sauce screw packaging machine, electronic combination scale screw packaging machine, Pillow-type screw packaging machine; according to the packaging function, there are inner packaging and outsourcing screw packaging machines; according to the packaging industry, there are screw packaging machines for food, daily chemicals, textiles, etc.; according to the packaging station, there are single-station, multi-station Station screw packaging machine; according to the degree of automation, there are semi-automatic, fully automatic screw packaging machines, etc. Most of the screw packaging machines in the prior art are used to put materials into the bag body, but this type of screw packaging machine generally uses a support The open method opens the bag mouth for loading. This method is not only easy to break the bag mouth, but also difficult to adjust the position of the bag body. In view of this, we propose a bag opening device for a screw packaging machine.
To achieve the above object, the utility model provides the following technical solutions:
A bag opening device of a screw packaging machine comprises a bottom plate arranged on a material screw packaging machine, a shaping table is arranged above the bottom plate, a connecting rod is arranged at the rear end of the bottom plate, and the rear end of the connecting rod is provided with The swing motor is fixed on the screw packaging machine, the end of the output shaft of the swing motor is fixedly connected with the end of the connecting rod, and the shaping table is a hollow structure with an upper opening. Two adjustment cylinders are symmetrically arranged on the inner walls of both sides, and the end of the piston rod of the adjustment cylinder is connected with an adjustment plate, and two guide plates and a channel enclosed by the two guide plates are arranged above one end of the shaping table. , at the entrance of the channel, there are two conveying pressure rollers that are close to each other, and the upper and lower sides of the shaping table and the position close to the other end are respectively provided with an upper bag opening suction cup and a lower bag opening suction cup
