Technical Field

[0001] The utility model relates to the technical field of packaging machines, in particular to a plastic bag sealing device used on a horizontal packaging machine. Background Art

[0002] Packaging machines are machines that package products to protect and beautify them. Packaging machines are mainly divided into two aspects: 1. Assembly line overall production packaging, 2. Product peripheral packaging equipment. Packaging machines are classified into: liquid (paste) filling machines, pillow packaging machines, horizontal packaging machines, vertical packaging machines, powder and granule packaging machines, bag-feeding automatic packaging machines, frozen product automatic packaging machines, etc.

[0003] The bag-feeding automatic packaging machine and filling machine open the bag mouth through the driving device, and then the material automatically falls into the bag, thereby completing the filling process. However, the bag sealing device currently on the market is installed separately. Even when the bag is filled with materials, the worker needs to take the bag filled with materials to the bag sealing device to seal the bag mouth. Therefore, the bag sealing process is troublesome, resulting in low production efficiency. Utility Model Content

[0007] Preferably, a supporting block is provided on one side of the two bag steaming devices corresponding to each other, and the groove and the protrusion are arranged on the supporting block.

[0008] Preferably, the bottom of the groove is set in a circular arc, and the top of the supporting block is set in a circular arc.

[0009] Preferably, the bag steaming device comprises a heat conducting pipe and a heat transfer shell; the heat conducting pipe is installed inside the heat transfer shell, and the heat conducting pipe generates heat and transfers heat to the heat transfer shell.

[0010] Preferably, the driver is a double-rod cylinder.

[0011] Preferably, an isolation block is installed between the driver and the cross bar.

[0012] The technical solution provided by the utility model can include the following beneficial effects: a cross bar is installed at the tail of the loading part, two ends below the cross bar are respectively installed with drivers, a bag ironing device is installed at the driving end of the driver, two drivers respectively drive the bag ironing devices to move simultaneously, the two bag ironing devices clamp the bag opening, and the bag ironing devices heat the bag opening to seal the bag opening. Since the cross bar, the driver and the bag ironing device are installed at the tail of the loading part, the bag opening can be sealed immediately after the bag is loaded with materials, which can effectively seal and improve production efficiency. A plurality of grooves and a plurality of protrusions are arranged on one side corresponding to each other of the two bag ironing devices, and the grooves and the protrusions are arranged alternately. The protrusions and the grooves can iron a plurality of wavy strips on the bag opening so that the bag opening can be further sealed. BRIEF DESCRIPTION OF THE DRAWINGS
