[0017] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0018] like Figure 1-3 As shown, a plastic bag sealing device comprises a sealing machine body, a pressing cover is hingedly provided at the upper end of the sealing machine body, a mounting plate is provided at the bottom of the inner cavity of the sealing machine body, two fixing plates are symmetrically provided at the upper end of the mounting plate, a round rod is movably provided on each of the fixing plates, a clamping plate is provided at one end of the round rod, a first spring is provided on the round rod and is located between the fixing plate and the clamping plate, a limiting disk is provided on the round rod and is located on one side of the outer wall of the fixing plate, a connecting plate is clamped between the two clamping plates, a second spring is provided at the lower end of the connecting plate, a connecting column is provided at the upper end of the connecting column, a heating plate is provided at the upper end of the connecting column, and a high-temperature cloth is provided at the upper end of the heating plate.

[0019] In this embodiment, when the sealing machine body needs to be inspected and maintained, the bolts and the positioning plate are first removed, and the two round rods are simultaneously pulled out in a direction away from the sealing machine body to drive the clamping plate to move, thereby canceling the limit on the connecting plate. The connecting plate moves upward under the elastic force of the second spring and drives the connecting column and the heating plate to be pushed upward, making it easy for people to take out the heating plate from the inside of the sealing machine body for maintenance, greatly reducing the time required for disassembly and maintenance.

[0020] like Figure 1 As shown, rollers are symmetrically arranged at the bottom of the clamping plate.

[0021] In this embodiment, rollers are provided to reduce the resistance of the clamping plate when it moves on the mounting plate.

[0022] like Figure 1 As shown, an anti-slip sleeve is provided at one end of the round rod.

[0023] In this embodiment, the anti-slip cover is provided to facilitate people to hold the round rod.

[0024] like Figure 1 As shown, positioning plates are installed on both sides of the upper end of the sealing machine body through bolts.

[0025] In this embodiment, the positioning plate is installed by using bolts, which makes it easy for people to disassemble and assemble the positioning plate.

[0026] like Figure 1 As shown, an electric heating net is arranged inside the heating plate, and the electric heating net is in contact with the bottom of the high-temperature cloth.

[0027] In this embodiment, the high temperature cloth is heated by providing an electric heating network.

[0028] Working principle: When the sealing machine body needs to be inspected and maintained, first remove the bolts and the positioning plate, and pull the two round rods away from the sealing machine body at the same time to drive the clamping plate to move, cancel the limit on the connecting plate, and the connecting plate moves upward under the elastic force of the second spring, while driving the connecting column and the heating plate to be pushed upward, so that people can take out the heating plate from the inside of the sealing machine body for maintenance, which greatly reduces the time required for disassembly and maintenance.
