[0027] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0028] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] like Figures 1 to 5 As shown, the fully automatic unpacking machine mainly consists of an outer frame unit 9, a feeding conveying unit 1, a bag shaping unit 10, a flipping unit 2, a long bag opening removal unit 5, a short bag opening removal unit 7, a cutting unit 4, a flipping and unloading unit 8, a waste bag collection unit 6, and an inner bag conveying unit 3. The feeding conveying unit 1 is installed on one side of the outer frame unit 9, and the bag shaping unit 10 is installed above the feeding conveying unit 1. The flipping unit 2 is installed on one side of the feeding conveying unit 1 and is located inside the outer frame unit 9. The long bag opening removal unit 5 is installed above the flipping unit 2, and the cutting unit 4 is installed on one side of the long bag opening removal unit 5. The flipping and unloading unit 8 is installed at the other end of the flipping unit 2. The inner bag conveying unit 3 is installed below the flipping and unloading unit 8. The waste bag collection unit 6 is installed above the flipping and unloading unit 8, and the short bag opening removal unit 7 is installed at the other end of the flipping and unloading unit 8.

[0030] Existing methods mostly involve manual bag opening or semi-automatic auxiliary mechanisms. This application presents a fully automatic solution with functions such as automatic shaping, automatic edge finding, edge smoothing, gripping, cutting, material unloading, and waste bag recycling.

[0031] In addition, the length of the flipping unit 2 in this application is 2 / 3 of the bag length. After flipping at a certain angle, the end of the bag is in a suspended position, which facilitates bag opening sorting and gripping. After flipping, the bag edge position is automatically identified. Through sorting, the mechanism only grips the outer bag edge to achieve separation of inner and outer bags, ensuring that the inner bag is not cut during cutting.

[0032] In a preferred embodiment of the present invention, both the feeding conveyor unit 1 and the inner packaging conveyor unit 3 are existing conveyor belt mechanisms. The bags are positioned here by the bag shaping unit 10, which is responsible for conveying the bags to the unpacking machine.

Both flipping and pouring cylinders 82 are installed on the outer frame unit 9. In actual use, the flipping and pouring unit 8: flips through the cylinders to complete the pouring out of the inner bag.

[0053] In a preferred embodiment of the present invention, the outer frame unit 9: installs all the above mechanisms, and the entire equipment is enclosed by an aluminum profile frame + plexiglass plate + stainless steel plate, and is equipped with multiple hinged doors for easy maintenance.

[0054] When using this invention, workers can place the product to be processed on the inlet conveyor line. After a series of functions such as positioning, cutting, and unloading, the outer packaging is removed, and the inner packaging is conveyed to the designated area by the conveyor component. This reduces the labor intensity of workers, and the bag unpacking and conveying efficiency is high, thus reducing production costs.

[0055] Working principle of a fully automatic package unpacking machine:

[0056] The product is laterally positioned by the cylinders on both sides of the bag shaping unit 10. After positioning, it enters the unpacking machine. The bag is conveyed to the flipping unit 2, which flips it at a certain angle. The bag opening removal unit 5 sorts and grips one side of the bag, lifts it, and moves it to the position of the cutting unit 4. The cutting knife moves laterally and cuts open the end of the bag, which falls onto the flipping unit 2. The flipping unit 2 flips back to the horizontal position, and the rear end block of the flipping unit 2 rises, conveying the bag to the next station (flipping and unloading station). The bag opening removal unit 7 grips the short side of the bag, and the cylinder of the flipping and unloading unit 8 flips, causing the inner bag to come out and fall onto the inner bag conveyor line. The cylinder of the flipping and unloading unit 8 resets, and the inner bag conveyor line of the inner bag conveying unit 3 starts, outputting from the unpacking machine to the next process.

[0057] It should be noted that all electrical components involved in this application are prior art.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
