Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0046] A packaged food unpacking device is a device that punctures the packaging bag of packaged food to pour out the food inside.

[0047] Please see Figure 1-10 As shown, the packaging food bag opening device includes: hopper 310, puncture component 320, bag collection component 330 and transmission component 340.

[0048] The hopper 310 has an opening at the top, through which packaged ingredients 00 fall into the hopper 310. Figure 1 and Figure 2 As shown, the packaged food 00 is packaged in a roughly cylindrical shape, specifically by inflating the packaging bag to make it cylindrical; the two ends of the packaging bag are respectively provided with knots 01, which can be knots formed by tying after the food is put into the packaging bag, or knots left after the food is put into the packaging bag and heat-sealed.

[0049] The aforementioned nodules can also be replaced by protrusions pre-installed on the packaging bag, handles pre-installed on the packaging bag, etc.

[0050] The hopper 310 has a notch 311 on at least one side, and packaged food 00 falls into the hopper 310. A portion of the bag of packaged food 00 protrudes from the notch 311; specifically, the nodules of packaged food 00 protrude from the notch 311.

[0051] like Figure 5 As shown, the two sides of the hopper 310 are symmetrical ( Figure 5 The upper and lower sides are respectively provided with notches 311. When the packaged food 00 is put into the hopper 310, the nodules at both ends of the packaged food 00 protrude from the notches 311. So, whether the packaged food 00 is placed in the hopper 310 in the forward direction or rotated 180° horizontally in the reverse direction, the bag pulling action can be performed afterwards.

[0052] The puncture assembly 320 has a knife holder 321 and a blade 322. The blade 322 corresponds to the front of the hopper 310. The blade 322 is mounted on the knife holder 321, which is mounted on the bracket of the packaged food unpacking device.

[0053] Alternatively, when a packaging bag-opening device is added to an automatic cooking equipment, the knife holder 321 is supported on the bracket of the automatic cooking equipment.

[0054] like Figure 2 As shown, blade 322 has a concave arc-shaped cutting edge to fit the cylindrical shape of the packaged food ingredient 00.

[0055] The bag collecting assembly 330 is located on the side of the hopper 310 where the notch 311 is provided, and has a fixed gear set 331, a moving gear set 332 and a bag collecting motor 333;

[0056] The transmission assembly 340 is used to drive the hopper 310 and the moving gear set 332 to move linearly;

[0057] The transmission assembly 340 drives the hopper 310 to move toward or away from the blade 322, and the transmission assembly 340 drives the moving gear set 332 to move toward or away from the fixed gear set 331.

[0058] Specifically, such as Figure 5As shown, the transmission assembly 340 drives the hopper 310 to move toward the blade 322, that is, to the right. The blade 322 punctures the packaged food in the hopper 310. After the transmission assembly 340 drives the moving gear set 332 to move toward the fixed gear set 331, it clamps a section of the packaged food between the fixed gear set 331 and the moving gear set 332. The fixed gear set 331 and the moving gear set 332 rotate in coordination, and the packaged bag is pulled out of the hopper 310 through gear transmission, leaving the food in the hopper 310.

[0059] Furthermore, such as Figure 9 As shown, the fixed gear set 331 includes: a bag-pulling gear A3311, a meshing gear A3312, and a bracket A3313. The bag-pulling gear A3311 and the meshing gear A3312 are mounted on the same rotating shaft. The output shaft of the bag-collecting motor 333 is connected to the meshing gear A3312, and the bag-collecting motor 333 drives the meshing gear A3312 and the bag-pulling gear A3311 to rotate.

[0060] The moving gear set 332 includes: a bag-pulling gear B3321, a meshing gear B3322, and a bracket B3323. The bag-pulling gear B3321 and the meshing gear B3322 are mounted on the same rotating shaft.

[0061] The bracket B3323 mainly serves a supporting function. The rotating shaft is installed on the bracket B3323, and the bag pull gear B3321 and the meshing gear B3322 are installed on the rotating shaft.

[0062] like Figure 2 As shown, there are two pull-bag gears B3321 and two meshing gears B3322, and the two meshing gears B3322 mesh with each other;

[0063] like Figure 10 As shown, during rotation, only one corresponding tooth of the two bag-pulling gears B3321 engages, and it is a shallow engagement. Specifically, one tooth F on one bag-pulling gear B3321 contacts one tooth E on the other bag-pulling gear B3321, and the outer ends of tooth F and tooth E in the radial direction contact each other, not completely, so that the packaging bag can pass through.

[0064] Alternatively, a certain gap can be left between the two bag-pulling gears B3321, so that they do not mesh, similar to the transfer rollers, to pull the packaging bag to move.

[0065] In one embodiment, the bag receiving assembly 330 further includes a bag receiving chamber 334, the opening of which corresponds to two bag pulling gears B3321. The packaging bag is pulled out from between the two bag pulling gears B3321 and enters the bag receiving chamber 334 to store the packaging bag. The bag is then cleaned periodically after storage.

[0066] like Figure 2As shown, after the packaging bag is pulled out, it enters the bag receiving compartment 334 in the direction indicated by the arrow.

[0067] like Figure 9 As shown, the moving gear set 332 moves toward the fixed gear set 331, that is, moves to the right. The meshing gear A3312 meshes with one of the meshing gears B3322. The bag-collecting motor 333 drives the meshing gear A3312 to rotate, which in turn drives the meshing gear B3322 and the bag-pulling gear B3321.

[0068] The bag-pulling gears A3311 and B3321 mesh, squeezing the knots of the packaging bag between them. When the gears rotate, they pull the packaging bag... Figure 9 The bracket A3313 is positioned upwards and is shell-shaped, with upper and lower bottom plates, left and right side plates, and a back plate. An opening is formed on the front, and the bag-pulling gear A3311 is located inside the shell. This opening allows the bag-pulling gear A3311 and the bag-pulling gear B3321 to engage. During the process of pulling out the packaging bag, the bag will accumulate inside the shell. After accumulating to a certain extent, the bag will enter between the two bag-pulling gears B3321, which will then drive the bag to rotate. Figure 2 Move in the direction indicated by the arrow into the bag collection compartment 334.

[0069] Alternatively, the bracket A3313 may be provided with a guide surface, which guides the packaging bag to turn during the process of pulling out the packaging bag, so that the packaging bag will enter between the two bag pulling gears B3321 and finally enter the bag receiving compartment 334.

[0070] Optionally, the bag collection compartment 334 can be fully pulled out to remove the packaging bag removal device for cleaning the packaging bags in the bag collection compartment 334; or the bag collection compartment 334 can be equipped with a door structure, which can be opened to clean the packaging bags inside.

[0071] In one embodiment, the transmission assembly 340 includes: two symmetrically distributed lead screws 341, two symmetrically distributed guide rods 342, a lead screw motor 343, and a transmission belt 344;

[0072] The ends of the two lead screws 341 are equipped with transmission gears, and the transmission belt 344 is wound around the two transmission gears; the lead screw motor 343 drives the two lead screws 341 to rotate synchronously.

[0073] Furthermore, a screw nut 345 is fitted on the screw 341, and the hopper 310 is rotatably mounted on the screw nut 345; a rotating shaft 312 is provided on one side of the hopper 310, and a rotating gear 3121 is provided on the rotating shaft 312; a threaded section 3421 is provided on the guide rod 342, and the guide rod 342 is driven to rotate by the guide rod motor 346, which in turn drives the hopper 310 to rotate around the horizontal axis.

[0074] Furthermore, the lead screw nut 345 is provided with a lever 3451; the transmission assembly 340 also includes a slide rail 347 and a cam 348;

[0075] The moving gear set 332 is mounted on the slide rail 347 via a slider, and the slide rail 347 is parallel to the lead screw 341; the lead screw nut 345 moves along the lead screw 341, and the lever 3451 pushes the cam 348 to rotate so as to push the moving gear set 332 to move along the slide rail 347.

[0076] like Figure 4 As shown, the screw motor 343 rotates in the forward direction, driving the screw 341 to rotate, and the hopper 310 moves to the right; during this process, as... Figure 9 As shown, the lever 3451 of the lead screw nut 345 actuates the cam 348, and the trigger rod on the cam 348 pushes the moving gear set 332. The moving gear set 332 moves along the slide rail 347, specifically as follows. Figure 4 As shown, move to the right.

[0077] During the rightward movement of the hopper 310, the blade 322 punctures the packaged food 00. After the hopper 310 completes its stroke, the bag-collecting motor 333 starts, driving the meshing gear A3312 and the bag-pulling gear A3311 to rotate. At the same time, it drives the meshing gear B3322 and the bag-pulling gear B3321. The meshing gear A3312 and the bag-pulling gear B3321, which is close to the hopper 310, cooperate to pull out the packaged bag. The two bag-pulling gears B3321 cooperate to pull the packaged bag into the bag-collecting chamber 334.

[0078] During the bag-pulling process of meshing gear A3312 and bag-pulling gear B3321 near hopper 310, the blade 322 has not yet retracted, thus widening the puncture opening to facilitate the leakage of food; Figure 7 As shown, the notch 311 is small, allowing the packaging bag to pass through the notch 311 and be delivered without the food being delivered.

[0079] like Figure 2As shown, the bag-pulling gear A3311 is mounted on the bracket A3313. Similarly, the bag-pulling gear B3321 is mounted on the bracket B3323. When the bag-pulling gear B3321 approaches the bag-pulling gear A3311, the cooperation between the brackets A3313 and B3323 forms a narrower opening for passing through the bag, which can prevent food from being pulled between the bag-pulling gears A3311 and B3321.

[0080] Bag-pulling gear A3311; meshing gear A3312; bracket A3313; drive gear set 332; bag-pulling gear B3321;

[0081] Furthermore, the front of the hopper 310 is provided with a piercing hole 313, through which the blade 322 enters the hopper 310 and pierces the packaged food.

[0082] Furthermore, such as Figure 3 As shown, the guide rod motor 346 drives the guide rod 342 to rotate, and then through the cooperation of the rotating gear 3121 and the threaded section 3421, the hopper 310 rotates around the horizontal axis until the opening of the hopper 310 faces downward, and the food is poured out from the opening of the hopper 310.

[0083] Of course, a receiving hopper or a frying pan or other structure is provided below the hopper 310.

[0084] like Figure 4-6 As shown, the packaging food unpacking device can be installed in the cooking equipment. The cooking equipment has a panel 400 on its support, and an opening is provided on the panel 400. A door 410 is provided at the opening, and the packaged food 00 falls into the hopper 310 through the opening.

[0085] like Figure 4 As shown, a toothed actuating arm 411 is provided at the door 410, and a toothed fixing arm 412 is provided at the screw nut 345; as the screw nut 345 drives the hopper 310 to move closer to the blade 322, the fixing arm 412 and the actuating arm 411 engage, causing the actuating arm 411 to rotate, which in turn causes the door 410 to rotate and open. When the hopper 310 moves to the opening directly opposite the panel 400, the door 410 is fully rotated open, and the packaged food 00 falls into the hopper 310 through the opening; the screw nut 345 drives the hopper 310 to move towards the blade 322;

[0086] Hopper 310 Figure 4 As shown, the door moves to the left. During the movement, the fixed arm 412 and the actuating arm 411 engage, causing the actuating arm 411 to rotate, which in turn causes the door body 410 to rotate and close.
