[0002] A packaging unpacking machine is a mechanical device used to unpack and break down the materials in packaging bags and transport them to subsequent production stages or storage equipment. Packaging unpacking machines can realize automatic feeding, cutting, separation, and conveying processes, which greatly improves production efficiency.

[0003] Existing unpacking machines, such as the one disclosed in publication number CN221438683U, have the advantages of high bag cutting qualification rate and small space occupation during equipment stroke. However, after the bags are unpacked, they are directly collected into the collection mechanism. This makes it inconvenient to tumble and screen the bags again during collection. As a result, some material remains in the bags, which leads to material waste. Therefore, we propose an unpacking machine that avoids material waste. Utility Model Content

[0026] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a packaging unpacking machine that avoids material waste.

[0027] Example 1:

[0028] Combination Figure 1-6As shown, the present invention provides a packaging unpacking machine to avoid material waste, comprising: a packaging unpacking machine body 100, a packaging unpacking component 200, and a separation component 300; the packaging unpacking component 200 includes a sieve plate 201 movably installed on one side inside the packaging unpacking machine body 100, a knife groove 202 arranged on one side of the sieve plate 201, a knife holder 203 movably installed in the knife groove 202, and a first electric push rod 204 fixedly installed at the outer end of the knife holder 203 in the side wall of the packaging unpacking machine body 100; The separation assembly 300 includes a screen cylinder 301 movably mounted on one side of the screen plate 201, screen holes 302 arranged on one side of the screen cylinder 301, a blocking strip 303 fixedly mounted on one side of the screen cylinder 301, a toothed ring 304 fixedly mounted on the outer end of the screen cylinder 301, an electric slide rail 305 fixedly mounted on the inner wall of the unpacking machine body 100 on one side of the screen plate 201, a slide block 306 movably mounted on the front end of the electric slide rail 305, and multiple sets of levers fixedly mounted on the bottom of the slide block 306. 307. A second electric push rod 205 is fixedly installed on both sides of the bottom of the sieve plate 201. A support plate 206 is fixedly installed at the bottom of each of the second electric push rods 205, and both ends of the support plate 206 are fixed to the inner wall of the unpacking machine body 100. A movable rod 308 is movably installed inside the lever 307, and the movable rod 308 has a T-shaped columnar structure. A gear 309 is meshed on the upper end of the gear ring 304, and a motor 310 is fixedly installed at one end of the gear 309. A fixing frame 311 is also fixedly installed at the outer end of the unpacking machine body 100, and both sides of the fixing frame 311 are fixed to the inner wall of the unpacking machine body 100. A fixing rail 312 is also fixedly installed at the outer end of the screen cylinder 301 on the outer side of the unpacking machine body 100. The fixing rail 312 is circular. A restraining plate 313 is also movably installed on both sides of the fixing rail 312. A fixing column 314 is also fixedly installed at the rear end of the restraining plate 313, and the inner side of the fixing column 314 is fixed to the outer wall of the unpacking machine body 100.

[0029] Specifically, a packaging unpacking machine is a mechanical device used to unpack and break down materials in packaging bags and transport them to subsequent production stages or storage equipment. The machine body 100 has multiple sets of knife slots 202 on one side of the screen plate 201, which can laterally separate and cut the outer end of the bag into multiple small segments when unpacking the bag at the top of the screen plate 201. This, combined with a second electric push rod 205 at the bottom of the screen plate 201 that lifts and shakes the bag, increases the speed at which the internal material falls out during unpacking and reduces material residue. Simultaneously, after the bag at the top of the screen plate 201 is unpacked, a fixed rail 312 on one side of the screen plate 201 will rotate to transport the multiple sets of cut and separated bags to the inside of the screen cylinder 301 outside the screen plate 201. When the bags are discharged, they are flipped by the screen cylinder 301, thus screening out any remaining material, ensuring complete discharge after unpacking and avoiding material waste. The screen cylinder 301 is equipped with various obstructions. The baffle 303 is mainly used to prevent the material bag from turning over after it is conveyed into the screen cylinder 301, thus causing the residual material inside to fall out. The gear 309 driven by the motor 310 at the upper end of the unpacking machine body 100 mainly drives the gear ring 304 at the outer end of the screen cylinder 301, thereby rotating the screen cylinder 301 inside the gear ring 304. The slide block 306 driven by the electric slide rail 305 mainly pushes the material bag out after separation through multiple sets of levers 307 and movable rods 308 at the bottom of the slide block 306, so as to convey it into the screen cylinder 301. The movable rod 308, which is movably installed at the bottom of the levers 307, mainly retracts during the up-and-down shaking of the screen plate 201 to avoid affecting the shaking of the screen plate 201. The fixed rail 312 fixedly installed on the outside of the screen cylinder 301, and the restraining plates 313 movably engaged on both sides of the fixed rail 312 are mainly used for stable restraint during the rotation of the screen cylinder 301 to ensure the stability of the screen cylinder 301 during rotation.

[0030] Working principle and usage process of this utility model:

[0031] When the material bag is conveyed to the upper end of the screen plate 201 inside the unpacking machine body 100 for unpacking, the first electric push rod 204 will be activated first to drive the knife holder 203 in the knife groove 202 to slide back and forth, thereby cutting and separating the material bag at the upper end of the screen plate 201 into multiple segments. After the material bag is cut, the second electric push rods 205 on both sides of the bottom of the screen plate 201 will be activated to shake the screen plate 201 up and down, thereby feeding the material inside the cut material bag into the unpacking machine body 100. After the material inside the material bag is fed out, the screen plate 201 stops shaking, and the electric slide rail 305 drives the outer end The slide block 306 moves, and during the movement, multiple sets of levers 307 and movable rods 308 at the bottom convey multiple material bags into the screen cylinder 301. The screen cylinder 301 will continue to rotate through the transmission of the gear 309 driven by the motor 310 to the gear ring 304. After multiple sets of material bags fall into the rotating screen cylinder 301, they will be flipped and moved downward by the rotating screen cylinder 301 and its internal multiple sets of blocking bars 303, thereby shaking off the residual material inside during the flipping and downward movement, so as to be collected into the unpacking machine body 100 through the screen holes 302 on the screen cylinder 301.

[0032] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
