Slider 92, and a cutting blade 93 disposed on the slider 92, the cutting blade 93 can be used to cut the semi-enclosed rubber film 30; the box-shaped container 20 can be pushed from the rear end to the front end of the guide space 10 to lift the pressure wheel portion 8 and the semi-enclosed rubber film 30 located below the pressure wheel portion 8. After being pushed in and passing over the pressure wheel portion 8, the cutting blade 93 can drive the slider 92 to slide on the slide rail 91 and cut the semi-enclosed rubber film 30 to form a sealing film 40 on the box-shaped container 20 that half covers the opening 202.

Among them, through the convenient sealing machine 100 of the present invention, through the cooperation of the base plate 1, the left bracket 2, the right bracket 3, the left column 4, the right column 5, the film frame 6, the guide part 7, the pressure wheel part 8 and the cutting knife part 9, the operation is simple, and the semi-closed film 30 can be fixed at the top sealing edge 201 of the box-shaped container 20 with the film roll 200, and the opening 202 of the box-shaped container 20 is half covered. In this way, not only the exhaust gap is maintained, but also the contents of the box-shaped container 20 are difficult to touch, so as to achieve the goal of taking into account both the needs of hygiene and safety and deliciousness, and the application range is wide.

Secondly, the mechanical structure is not prone to failure and maintenance, which can meet the broad market demand and bring food hygiene to another level.

Furthermore, the box-shaped container 20 can be pushed along the guide space 10 between the left bracket 2 and the right bracket 3. During the pushing process, the semi-enclosed rubber film 30 will be pressed and adhered to the box-shaped container 20 through the pressure wheel part 8, and then the knife part 9 cuts it, and the sealing operation is completed. The operation is very intuitive, which can reduce the door to get started, is fast and simple, and the operation is very intuitive, which is conducive to the promotion of products.

On the other hand, during the operation, all components do not require electricity.

Compared with traditional automatic sealing machines, there is no energy cost and it is very environmentally friendly.

In addition, the film holder 6 is universal, easy to use, and does not require any barriers to use. Users do not need to worry about not knowing how to use it, so that users can quickly get started, reduce learning costs, and are conducive to promotion.

Before using the convenient sealing machine 100 of the present invention, the box-shaped container 20 is placed in the guide space 10, as shown in FIG4, and then pushed to the pressure wheel portion 8 along the left bracket 2 and the right bracket 3, as shown in FIG8. As the box-shaped container 20 is pushed in, not only the pressure wheel portion 8 is lifted up, but also the semi-enclosed adhesive film 30 pressed and adhered under the pressure wheel portion 8 is lifted up together, as shown in FIG9. In this way, due to the pressure of the pressure wheel portion 8, the adhesive layer 302 on the semi-enclosed adhesive film 30 will be tightly attached to the corresponding top sealing edge 201.

Afterwards, as the box-shaped container 20 is pushed through the pressure wheel portion 8, since one end of the semi-enclosed rubber film 30 has been fixed on the box-shaped container 20, the semi-enclosed rubber film 30 will be dragged along with the box-shaped container 20, and the semi-enclosed rubber film 30 will be continuously pressed against the box-shaped container 20 by the pressure wheel portion 8. During the process, the user only needs to concentrate on pushing the box-shaped container 20. After the box-shaped container 20 completely passes over the roller portion 8, as shown in Figures 5 and 10, the semi-enclosed adhesive film 30 will half-cover the opening 202 of the box-shaped container 20. This is because the two shorter sides of the semi-enclosed adhesive film 30 without the adhesive layer 302 will not be attached to the box-shaped container 20, leaving a venting gap to allow the heat to be discharged without allowing people to steal food, so it is called semi-covering.

Next, as shown in Figures 6 and 7, the cutting knife 93 is pulled and cut along the slide rail 91 to cut the semi-enclosed rubber film 30. At this time, a sealing film 40 is formed on the box-shaped container 20 to half cover the opening 202 of the box-shaped container 20.
