Full-automatic plastic bag sealing machine

Abstract

The invention discloses a full-automatic plastic bag sealing machine which comprises a machine body, wherein two oppositely moving cross beams are mounted on the machine body; a group of transmission mechanisms for driving the cross beam to horizontally and linearly move in a reciprocating way are connected to each cross beam; electric heating sealing clips are fixedly mounted on the opposite side surfaces of the two cross beams; supporting rods and swinging mechanisms are arranged above the cross beams; the supporting rods are used for supporting and tensioning a plastic bag; the swinging mechanisms are used for driving the supporting rods to swing, so that the operation of supporting the plastic bag can be full-automatically finished; therefore, the automation degree of the sealing machine is greatly enhanced, the whole operation process is more consistent and automatic and the production efficiency can be obviously increased. Suckers and plastic bag locking mechanisms are also mounted on the cross beams, wherein the suckers are used for fixing the plastic bag; therefore, the plastic bag is more stably and reliably fixed on the cross beams, so that greater convenience for filling follow-up products and sealing the plastic bag is achieved.

Description

technical field [0001] The invention relates to a fully automatic plastic bag sealing machine. Background technique [0002] At present, the existing plastic bag sealing machines usually only include the sealing operation part of the plastic bag, and before the plastic bag is sealed, the plastic bag is stretched and the product is placed in the plastic bag, which is still done manually, thus causing the existing The degree of automation of plastic bag sealing machines is not high, the entire operation process is inconsistent, and the production efficiency is low. At the same time, the structure of the plastic bag sealing operation part mainly includes two opposite-moving beams, each beam is fixed with an electric heating sealing clip, and each beam is connected with a transmission mechanism that drives it to move back and forth in a straight line. Driven by the transmission mechanism, the two electric heating sealing clips clamp each other to seal the plastic bag. After the...

Problems solved by technology

And the transmission mechanism that drives every crossbeam to move on the existing sealing machine mainly contains two kinds, and a kind of is made of two cylinders, and two cylinders are affixed with the two ends of crossbeam respectively, and another kind is made of one cylinder, described The cylinder is firmly connected to the middle of the beam. When the transmission mechanisms of these two structures drive the beam to move back and forth in a straight line, it is difficult to accurately keep the two ends of the beam always moving synchronously, resulting in the existence of two electric heating sealing clips when they are closed and clamped together. Gaps, which in turn affect the quality of the seal

In addition, the connection between the plastic bag and the beam on the existing sealing machine is only fixed by the suction cup. In practical applications, due to factors such as the weight of the product in the plastic bag, the plastic bag is only fixed by the suction of the suction cup, which is often not enough. Stable and reliable
