Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1 to 4, the sealing device of a vegetable and fruit packaging machine capable of controlling a feeding speed of the present invention comprises a first conveying line 1, a film forming plate 2, a film pulling device 5 for pulling a film a and pressing two edges A1 of the film a, and a middle sealing device 6 for heat-sealing and bonding the two edges A1; the film forming plate 2, the film drawing device 5 and the middle sealing device 6 are sequentially arranged along the conveying direction of the first conveying line 1;

the film drawing device 5 is provided with two rollers, the two edges A1 are tightly pressed through the two rollers, and the rollers are rotated by a power mechanism to provide power for film drawing; after being drawn by a film drawing device 5, the film A is folded into a U shape under the action of the gravity of the vegetable and fruit B; two rollers on the traction device are used for pressing two edges A1 of the film A tightly, so that the film A is formed into a cylindrical shape;

the cross section of the film forming plate 2 is U-shaped, and the height of the top surface of the film forming plate 2 is gradually increased along the direction close to the film drawing device 5; two hot pressing wheels are arranged on the middle sealing device 6, and hot-press bonding is carried out by rolling two edges A1 through the two hot pressing wheels;
