detailed description

The technical solutions of the present utility model will be further specifically described below through specific embodiments and in conjunction with the accompanying drawings.

Embodiment: A vacuum heat-sealing mechanism of vacuum packaging equipment (see accompanying drawing 1 and accompanying drawing 2), which cooperates with the conveying device of vacuum packaging equipment, and includes a vacuum cover 9 hinged on the frame 1, and the hinged part of the vacuum cover deviates from the vacuum cover , the side of the vacuum cover is connected to the vacuum pump through the vacuum tube 5, a heat-sealing strip 6 is arranged on the inner top wall of the vacuum cover, and the heat-sealing strip is connected to the heat-sealing control device through the heat-sealing control line 7, and the top of the vacuum cover is provided with a device that can detect the inside of the vacuum cover. Vacuum gauge 8 for vacuum degree.

The vacuum cover has a Western-shaped structure as a whole, and a ring of elastic seals 10 is provided on the entire edge of the square. The edge of the vacuum cover is provided with a concave slot, the cross section of the elastic seal is annular and hollow, and the side of the elastic seal is provided with a connecting edge, and the connecting edge is snapped into the slot on the edge of the vacuum cover.

A hinge seat 4 is respectively fixed on the position corresponding to both sides of the vacuum cover on the frame, and the hinge seat is composed of two parallel hinge pieces 12, and a rotating shaft 13 is hinged on the two hinge pieces. 3 phase fixed. Both sides of the vacuum cover are fixed with reinforcing blocks 11, and two parallel fixed rods 14 are fixed on the reinforcing blocks, and the fixed rods are fixed to the end positions of the drive rods, and the two fixed rods are on the same plane as the drive rods. On the driving rod, a connecting rod 15 is vertically fixed, and the connecting rod is vertical to the driving rod, and the rotating shaft, the driving rod, the connecting rod and the fixed rod are all in the same plane. The connecting rod is hinged with the driving device. In the present embodiment, the driving device is driven by the lifting cylinder 2.
