[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example:

[0025] See also Figure 1-Figure 2 The utility model provides a pre-prepared dish sealing device, including a conveyor belt 1, a film belt 2 is arranged above the conveyor belt 1, a lower pressure roller 3 is arranged above the film belt 2, a vegetable box sealing film 4 is arranged on the conveyor belt 1 in a matrix structure, a cylinder 5 is arranged above the film belt 2, a base plate 6 is fixedly installed at the inner rod end of the cylinder 5, an air pump 7 is fixedly installed on the lower side of the base plate 6, an air outlet plate 8 is arranged at the air outlet position of the air pump 7, and an electric heating frame 9 is fixedly installed on the outer side of the air outlet plate 8.
