It is installed on the frame 10 and is located directly below the pressing end of the pressing piece 20; the control unit 50 is installed on the frame 10 and the pressing piece 20, and is connected to the heating unit 40. The pressing piece 20 is pressed down by the power unit 30 so that the pressing piece 20 is in the second pressing state. The pressing piece 20 touches and turns on the control unit 50 to drive the heating unit 40 to heat. The pressing piece 20 seals the plastic to be processed above the heating unit 40. When the pressing piece 20 is not pressed down by the power unit 30, the pressing piece 20 is reset and the control unit 50 is closed.

[0020] Through the arrangement of the frame 10, the lower pressing piece 20, the power unit 30, the heating unit 40 and the control unit 50, the plastic bag to be sealed is placed on the heating unit 40, the power unit 30 drives the lower pressing piece 20 to rotate on the frame 10, and the lower pressing piece 20 triggers the opening of the control unit 50 during the process of rotating and pressing down. The control unit 50 energizes and heats the heating unit 40 during the pressing stroke of the lower pressing piece 20, and the pressing end of the lower pressing piece 20 presses the plastic bag to be sealed on the heating unit 40 to achieve the sealing of the plastic bag.

In this plastic packaging sealing machine, when the pressing member 20 is not pressed down, the control unit 50 is not turned on, and the heating unit 40 is not powered on for heating. When the pressing member 20 is pressed down, the control unit 50 is turned on, and the control unit 50 powers on and heats the heating unit 40. The pressing member 20 drives the plastic bag to be pressed against the heating unit 40 to seal the plastic bag, effectively avoiding accidental touching, scalding, and electric shock to the staff, and improving the safety of the plastic bag during the sealing process.

[0021] like Figure 1 , Figure 2 As shown, in this embodiment, specifically, the pressing member 20 includes a pressing arm 21, a spring hinge 22, a pressing plate 23 and a heat-resistant adhesive strip 24; the pressing arm 21 has a connecting end and a pressing end, the connecting end is rotatably connected to the frame 10 through the spring hinge 22, and the pressing plate 23 is mounted on the pressing end. The heat-resistant adhesive strip 24 is mounted on the pressing plate 23, and the heat-resistant adhesive strip 24 is located directly above the heating portion 40.

[0022] The heat-resistant rubber strip 24 has a certain elastic deformation capability to ensure the compaction effect on the plastic bag.

[0023] In this embodiment, the pressing arm 21 is connected to the pressing plate 23 by bolts, so as to facilitate the installation, disassembly and replacement of the pressing plate 23 .

[0024] like Figure 1 , Figure 2 , Figure 3 As shown, in this embodiment, further, the power unit 30 includes a connecting member 31 and a pedal 32, the pedal 32 can be rotatably connected to the frame 10, the connecting member 31 can be movable on the frame 10, and the top end of the connecting member 31 is connected to the pressure arm 21, and the bottom end of the connecting member 31 is connected to the pedal 32.

[0035] When the pressing arm 21 rotates, the trigger block 52 moves with the movement of the pressing arm 21. The pressing arm 21 rotates the trigger block 52 to trigger the micro switch 51 to turn on. The micro switch 51 energizes and heats the heating wire 42 through the electronic control system 53. When the pressing arm 21 is reset, the trigger block 52 is not in contact with the micro switch 51, and the heating wire 42 is not energized at this time.

[0036] When sealing a plastic bag, the plastic bag to be sealed is placed on the supporting seat 41, and the foot pedal 32 is stepped on. The foot pedal 32 drives the pressing arm 21 to be pressed down through the first connecting rod 311 and the second connecting rod 312. The pressing arm 21 drives the trigger block 52 to trigger the micro switch 51 to turn on. The micro switch 51 energizes and heats the heating wire 42 through the electronic control system 53. At the same time, the pressing plate 23 drives the heat-resistant adhesive strip 24 to seal the plastic bag to be sealed on the supporting seat 41 as the pressing arm 21 rotates. The foot pedal 32 is lifted, and the spring hinge 22 resets the pressing arm 21. The trigger block 52 is separated from the micro switch 51. At this time, the heating wire 42 is not heated.
