[0045] The working principle of the utility model is as follows: before folding the spring roll wrapper, first adjust the height of the wrapper turning mechanism through the lifting component; adjust the position of the tracking moving mechanism and the wrapper turning component through the position adjustment component, and ensure that the synchronous belt 20 and the spring roll conveyor belt move at the same speed.

[0046] When the spring rolls are folded, they are transported on the conveyor belt.

When the moving plate 30 moves to the right following the synchronous belt 20, the piston rod of the flipping cylinder 40 drives the driving connecting rod 41 to rotate. The driving connecting rod 41 drives the special-shaped connecting rod 42 to rotate through the rotating shaft 38. The connecting rod shaft 43 at the end of the special-shaped connecting rod 42 slides in the strip sliding hole 45, so that the flipping seat 44 rotates upward. The flipping seat 44 drives the mold plate 46 to flip upward. The spring roll skin folding action is completed in the process of the mold plate 46 flipping upward, thereby completing the folding of the spring roll skin on the right side.

[0047] When the sensing plate 31 moves to above the sensor 32 located on the right end of the movable plate 8, the sensor 32 transmits a signal to the control cabinet, which controls the reversal of the servo motor 16, and the synchronous belt 20 transmits in the opposite direction to restore the flipping skin assembly to its initial position. In this process, the mold plate 46 is driven to return to its initial state through the cooperation of the flipping cylinder 40 and the connecting rod structure, waiting for the next spring roll skin to be folded.

[0048] The spring roll with the right side folded continues to be conveyed forward on the conveyor belt. When it moves to the position of the second flipping folding mechanism, the second flipping folding mechanism starts to operate, and then the left side folding of the spring roll is completed. The movement process is the same as that of the first flipping folding mechanism.

[0049] The embodiments described above are only preferred embodiments of the utility model and do not limit the scope of implementation of the utility model. Therefore, all equivalent changes or modifications made according to the technical solutions described in the patent scope of the utility model should be included in the scope of the patent application of the utility model.
