As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.
[0019] like Figures 1 to 4 As shown, an essential oil box film sealing device includes a conveying channel 100. A push plate 200 driven by a first cylinder 210 is provided at the front end of the conveying channel 100 for pushing the essential oil box backward. Rear folding plates 300 are provided on both sides of the conveying channel for folding the rear sides of the film inward when the essential oil box moves backward. Front folding plates 400 are provided on both sides of the push plate for moving forward and backward and folding the front sides of the film inward when moving backward. The front end of the rear folding plate 300 and the rear end of the front folding plate 400 are both trapezoidal in shape. An upper folding plate 500 is provided behind the rear folding plate for folding the upper sides of the film inward. A lower folding plate 600 is provided behind the upper folding plate for folding the lower sides of the film inward. After the essential oil box is coated in the previous process, both ends of the film are still in an open state, such as Figure 3 As shown, the coated essential oil box can be transported to the front end of the conveying channel 100 (i.e., the rear position of the push plate 200) manually or by other conveying methods; the essential oil box sealing device of the utility model needs to be used to fold and heat-seal the two ends of the film, and the folding order is as follows: the rear folding plate 300 folds the rear side of the film end inward, the front folding plate 400 moves backward to fold the front side of the film end inward, the upper folding plate 500 folds the upper side of the film end inward, and the lower folding plate 600 folds the lower side of the film end inward; after the folding of the four sides of the film end is completed, it is heat-sealed and fixed.
