The film is placed in the product in the opening after passing through the lower frame, the first side frame, the upper frame and the second side frame in sequence. Since the negative pressure fan is located at the position close to the first side frame on the bottom side of the lower frame, the negative pressure suction force of the film when entering the conveying belt can be enhanced, and the conveying effect of the film along with the conveying belt can be ensured.

The first transition belt 33 is drivingly connected between the lower synchronous wheel 25 on the right side and the right synchronous wheel 26 on the lower side. The second transition belt 34 is drivingly connected between the right synchronous wheel 26 on the upper side and the upper synchronous wheel 27 on the right side. The third transition belt 35 is drivingly connected between the left synchronous wheel 28 on the left side and the left synchronous wheel 28 on the upper side. The first transition belt 33 is obliquely arranged between the lower synchronous belt 21 and the right synchronous belt 22, and can guide the film when conveying from the lower synchronous belt 21 to the right synchronous belt 22, thereby improving the stability of the film conveying when turning.
