Embodiment 1

[0026] When in use, the forming box 3 is placed in the supporting mold 1, and the cylinder drives the supporting mold 1 to move up to make it combine with the upper chamber seat 2, and the forming box 3 is fixed on the supporting mold 1 and the upper chamber seat 2. In the formed sealing cavity, an antibacterial film is provided on the contact surface of the upper seat chamber 2, the supporting mold 1 and the forming box 3, and the antibacterial film can effectively inhibit the growth of bacteria, and avoid the health hazard caused by the growth of bacteria in the forming box;

[0027] The cylinder drives the heat-sealing plate 5 to move down, and the temperature of the heat-sealing plate 5 is controlled by a temperature control meter; the heat-sealing plate 5 seals the lower film 4 located below it on the forming box 3, and the forming box 3 is higher than the upper film. 4 15mm wide, to complete the seal.

[0028] Heat-sealing plate 5 is provided with temperature sensor 8, a...

Embodiment 2

[0030] When vacuuming is required, the upper air valve 6 and the lower air valve 7 are opened, so that the sealing cavity formed by the supporting mold 1 and the upper chamber seat 2 is pumped up and down simultaneously to avoid pressure difference and ensure the vacuuming effect. After vacuuming, the upper gas valve 6 and the lower gas valve 7 can switch the gas valves to charge inert gas. According to the present invention, an upper air valve 6 and a lower air valve 7 are respectively provided on the upper chamber seat 2 and the supporting mold 1, so that the sealing cavity formed by the supporting mold 1 and the upper chamber seat 2 can be vacuumized or inflated. Easy to operate.

Abstract

The invention discloses a sealing device of a thermal forming packaging machine. The sealing device comprises a sealing cavity formed by combining a bearing mold and an upper chamber seat. A forming box is arranged in the bearing mold. A thermal sealing plate is arranged in the upper chamber seat and seals an upper film to the forming box. The thermal sealing plate is driven by an air cylinder. The sealing device is simple in structure, the forming box is arranged in the sealing cavity formed by combining the bearing mold and the upper chamber seat, and the forming box can be fixed effectively; and the upper film is sealed to a forming plate through the thermal sealing plate, the sealing yield can be effectively increased, and the beneficial effects are remarkable.

Description

technical field [0001] The invention relates to a sealing device of a thermoforming packaging machine. Background technique [0002] The foreign packaging industry is developing towards full automation. The extensive use of automatic packaging machinery and automatic packaging lines can achieve the requirements of high efficiency and low cost. As the fastest growing economic entity, my country is growing into the world's manufacturing and packaging center, and the demand for various automated packaging production lines will further increase. [0003] Relevant experts pointed out that, compared with foreign packaging line manufacturers, there is still a certain gap between domestic manufacturers' production line supporting performance consistency, equipment stability, and service life. In order to adapt to the rapidly growing domestic packaging demand, relevant enterprises must increase technical research and product innovation of specialized packaging lines, and better gra...
