Bag opening mechanism of packaging bag for nut packaging machine

Abstract

The invention relates to the technical field of nut packaging machines, in particular to a bag opening mechanism of a packaging bag for a nut packaging machine. The bag opening mechanism comprises a mounting pipe, wherein one side of the mounting pipe is connected with a sliding rod through a pushing assembly, a suction assembly is arranged on the other side of the mounting pipe, the outer wall of the sliding rod is provided with push-pull assemblies, and the push-pull assemblies are positioned in the mounting pipe. The packaging bag is adsorbed through air suction holes formed in the inner wall of the mounting pipe, the packaging bag is extruded and fixed through an extrusion disc, the packaging bag can be smoothened and leveled through sliding of two rubber plates on the surface of the packaging bag, and the situation that the packaging bag is adsorbed by the air suction holes to generate a large number of wrinkles, and consequently adsorption of vacuum suction cups is unstable is avoided; and one side of the packaging bag is adsorbed and fixed through the air suction holes, the other side of the packaging bag is adsorbed through the vacuum suction cups, the packaging bag is opened under the action of a hydraulic cylinder, the two vacuum suction cups conduct adsorption at the upper end and the lower end of the surface of the packaging bag to open the packaging bag, the packaging bag can be completely opened, and the situation that nuts are difficult to pour into the packaging bag due to the fact that the inner side of the packaging bag is adsorbed by static electricity is avoided.

Description

technical field [0001] The invention relates to the technical field of nut packaging machines, in particular to a bag opening mechanism for packaging bags used in nut packaging machines. Background technique [0002] The nut packaging machine is used for quantitative weighing packaging of peanuts, cashew nuts, pistachios, walnuts and other nuts, pesticides, feed, additives, washing powder, salt, monosodium glutamate, sugar, seeds, rice, pepper and other granular and powdery materials; currently, The process of packaging mixed nuts is as follows: transport the nuts to the electronic scale, and according to the quality display of the electronic scale, return more nuts and less supplement nuts to achieve the target quality, then pour the nuts that meet the quality requirements into the packaging bag, and then use the sealing device The packaging bag is sealed, and finally the packaged nuts are sold. [0003] In the process of packaging nuts, it is necessary to use the packagin...

Problems solved by technology

[0003] In the process of packaging nuts, it is necessary to use the packaging machine to heat seal the bagged nuts to seal the nuts in the packaging bag. It is necessary to manually cover the packaging bag at the nut outlet of the packaging machine to pick up a certain amount. After a large amount of nuts, the packaging bag is packaged with a packaging machine, which is inefficient for packaging nuts, and when the packaging bag is opened, it is easy to cause damage to the opening of the packaging bag due to its opening force. Therefore, in order to solve this problem To deal with such problems, we propose a bag opening mechanism for packaging bags used in nut packaging machines
