feeding cotton and prepressing: advancing the cotton feeding hydraulic cylinder → advancing the prepressing hydraulic cylinder → retreating the cotton feeding hydraulic cylinder → retreating the prepressing hydraulic cylinder → advancing the cotton feeding hydraulic cylinder → retreating the prepressing hydraulic cylinder

Turning a box to perform positive pressure: the positive pressure lifting box hydraulic cylinder retreats → the lifting box cylinder advances → the positive pressure hydraulic cylinder advances → the cotton feeding hydraulic cylinder advances → the prepressing hydraulic cylinder advances → the cotton feeding hydraulic cylinder retreats → the prepressing hydraulic cylinder retreats → the cotton feeding hydraulic cylinder advances → the prepressing hydraulic cylinder retreats.

Bundling and pushing out: the positive pressure tank raising cylinder retreating → the positive pressure hydraulic cylinder unloading → the push-out hydraulic cylinder advancing → the positive pressure hydraulic cylinder retreating → the push-out hydraulic cylinder retreating → the positive pressure tank raising hydraulic cylinder retreating → the pre-pressing tank raising hydraulic cylinder advancing → the positive pressure hydraulic cylinder advancing → the next cycle.

In the above, the forward movement is the extension of the push rod of the hydraulic cylinder, and the backward movement is the contraction of the push rod of the hydraulic cylinder. When the positive pressure is generated, the pre-pressing is also operated, and the next cotton bale is converted to the positive pressure by the pre-pressing after the positive pressure is finished.

The above description is only illustrative of the preferred embodiments of the present invention, and any variations, modifications, decorations, etc. may be made without departing from the principle of the present invention, and these variations, modifications, decorations, etc. are all considered to be within the scope of the present invention.
