Detailed Description of the Embodiments

[0022] In order to better explain the present utility model for easier understanding, the following will describe the present utility model in detail with reference to the accompanying drawings and through specific embodiments.

[0023] As Figures 1 to 3 shown, a sealing mechanism of the present utility model includes a bottom plate 1, a heating sheet 2, a clamping assembly 3 and an adjusting assembly 4; the heating sheet 2 is arranged on the bottom plate 1, one end of the heating sheet 2 forms a first positioning sheet 21, and the other end of the heating sheet 2 forms a second positioning sheet 22; the clamping assembly 3 includes a fixed seat 31 and a locking seat 32, the fixed seat 31 is arranged on one side of the bottom plate 1, the locking seat 32 is arranged on the fixed seat 31, and a first locking space for locking the first positioning sheet 21 is formed between the locking seat 32 and the fixed seat 31; the adjusting assembly 4 includes a connecting seat 41, a mounting seat 42, a tensioning block 43 and a spring 44, the connecting seat 41 is arranged on the other side of the bottom plate 1, the mounting seat 42 is arranged on the connecting seat 41, the tensioning block 43 is rotatably arranged on the mounting seat 42, a second locking space 431 for locking the second positioning sheet 22 is formed in the tensioning block 43, one end of the spring 44 is arranged on the connecting seat 41, and the other end of the spring 44 is arranged on the tensioning block 43 so that the tensioning block 43 has a tendency to move away from the connecting seat 41.

[0024] In this way, for a sealing mechanism involved in the present utility model, during use, the clamping assembly 3 can be fixed on one side of the lifting plate, and the adjusting assembly 4 can be fixed on the other side of the lifting plate, so that when the lifting plate moves up and down, the heating sheet 2 moves up and down synchronously to realize heat sealing of the barrier bag. During the heating process of the barrier bag, when the heating sheet 2 deforms due to heat expansion, the spring 44 pushes the tensioning block 43. Since the spring 44 makes the tensioning block 43 have a tendency to move away from the connecting seat 41, under the action of the spring 44, the tensioning block 43 pulls the heating sheet 2 outwards, so that when the heating sheet 2 is heated, the heating sheet 2 always remains in a tensioned state, effectively reducing the deformation phenomenon of the heating sheet 2 in the vertical direction, and thus achieving good heat sealing effect of the barrier film.

[0025] Optionally, an elastic buffer pad 5 is arranged between the heating sheet 2 and the bottom plate 1. By arranging the elastic buffer pad 5, when the lifting plate is lifted and the heating sheet 2 abuts against the barrier bag, the elastic buffer pad 5 has a buffering effect, so that the heating sheet 2 is not easily damaged.
