Embodiment 1

[0020] like Figure 1~3 As shown, a sealing frame device includes an upper sealing frame 1 and an electric heating rod assembly, the bottom of the upper sealing frame 1 is provided with a sealing silica gel strip 2, and the sealing silica gel strip 2 is arranged opposite to the electric heating rod assembly. The electric heating rod assembly described above includes a hollow electric heating rod main body 3, a heating mechanism arranged on the upper end surface of the electric heating rod main body 3, and an air filling nozzle 4. Specifically, in this embodiment, the electric heating rod main body 3 is made of metal material as an example, as Figure 4 As shown, the heating mechanism includes a heating wire 33 installed on the heating rod body 3 through fasteners and a high-temperature sealing cloth 34 attached to the outside of the heating wire 33 , between the heating wire 33 and the heating rod body 3 An insulating layer 35 is provided, one end of the inflation nozzle 4 is ...

Embodiment 2

[0025] like Figure 5 As shown, the inflating nozzle 4 and the opening in the bottom of the electric heating rod body 3 in the first embodiment are omitted, which communicate with the inflating pipeline at the bottom of the vacuum chamber 5, and other structures are the same as in the first embodiment. This structure is suitable for vacuum packaging machines that do not need to fill the vacuum bag with nitrogen or other protective gases. Its vacuumizing and sealing principle are identical with embodiment 1.

Abstract

The invention belongs to the technical field of vacuum packaging, and discloses a sealing frame device. The sealing frame device comprises an upper sealing frame and an electric heating rod assembly,wherein a sealing silica gel strip is arranged at the bottom of the upper sealing frame, and the sealing silica gel strip and the electric heating rod assembly are oppositely arranged; and the electric heating rod assembly comprises a hollow electric heating rod main body and a heating mechanism arranged on the electric heating rod main body, and a lifting mechanism used for driving the electric heating rod assembly to be close to or far away from the sealing silica gel strip is arranged at the bottom of the electric heating rod assembly. According to the sealing frame device, the electric heating rod assembly is arranged to be hollow, so that the problem of accumulated temperature rise of the heating mechanism is solved, and the service life of the heating mechanism is prolonged; and moreover, a wire pressing structure is used for preventing a vacuum bag from being wrinkled, and a pluggable air bag is beneficial to disassembly and maintenance of the air bag.

Description

technical field [0001] The invention belongs to the technical field of vacuum packaging, in particular to a sealing frame device. Background technique [0002] The sealing frame device is a device that must be used on the vacuum packaging machine. The existing inflation device on the vacuum packaging machine is to open 2 to 3 holes in the vacuum chamber, and install the inflation nozzle to connect them with the inflation pipeline under the vacuum chamber. The disadvantage is that This structure has a small amount of inflation, and the pipeline arranged under the vacuum chamber is increased; the sealing frame device includes the upper sealing frame on the vacuum cover (the lower part of which is provided with a sealing silica gel strip), the lower sealing rod assembly, and the pressing wire for pressing the bag. structure, metal base and lower airbag. Sealing rod components are generally made of solid epoxy plate sealing rod components, this material is not easy to dissipate...
