[0026] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0027] Please see Figures 1-7 One embodiment provided by this utility model:
[0028] An automatic bag unpacking and feeding machine includes a roller conveyor line 01 and a frame 03. Lifting cylinders 0302 are installed on both sides of one end of the frame 03.

It is used to collect and discharge the cut empty bags. The vacuum discharge machine 09 is fixedly set at the bottom of the hopper 07. It is used to transport the material in the hopper 07 to the material receiving end. The dust removal and ventilation device 04 is fixedly set in the frame 03. It is used to discharge the dust generated during the material discharge process. The CIP cleaning device 05 is fixedly set with several cleaning nozzles 0502. The cleaning nozzles 0502 are distributed inside the frame 03. They are used to clean the inside of the equipment after the material is fed.
[0029] The bag flipping mechanism 02 includes a bag support 0201 and a flipping cylinder 0205. The bag support 0201 is open at both ends and has short shafts 0202 fixedly installed on both sides. The short shafts 0202 are rotatably connected to first bearing seats 0203. The first bearing seats 0203 are respectively fixedly installed on both sides of the frame 03. One of the short shafts 0202 is fixedly connected to a crank 0204 at its end. The piston rod end of the flipping cylinder 0205 is hinged to the crank 0204. The bottom of the flipping cylinder 0205 is hinged to the frame 03. By pushing and pulling the crank 0204 through the flipping cylinder 0205, the bag support 0201 can be driven to rotate up and down around the short shaft 0202. In the initial position, the bag support 0201 forms an angle of 15-20 degrees with the horizontal plane, which facilitates the bag 12 to slide down by gravity.
[0030] The material blocking and bag discharging device 06 includes a rotating shaft 0601, a material blocking cylinder 0605, a connecting rod 0607, and a limiting mechanism. The rotating shaft 0601 has a baffle 0602 fixedly connected to its shaft body and second bearing seats 0603 at both ends. The second bearing seats 0603 are fixedly mounted on both sides of the frame 03. A positioning block 0604 is fixedly connected to one end of the rotating shaft 0601. The limiting mechanism includes a first limiting plate 0608 and a second limiting plate 0609. A certain distance is maintained between the first limiting plate 0608 and the second limiting plate 0609, and they are fixedly connected by a pin 0610 and a nut. The first limiting plate 0608 is connected to the frame 03. 3. Fixed connection: The first limiting plate 0608 and the second limiting plate 0609 are rotatably connected to the rotating shaft 0601 and located on both sides of the positioning block 0604. The bottom of the material blocking cylinder 0605 is hinged to the frame 03. The piston rod end of the material blocking cylinder 0605 is hinged to the connecting plate 0606. One end of the connecting rod 0607 is hinged to the connecting plate 0606, and the other end is hinged to the positioning block 0604. The first limiting plate 0608 and the second limiting plate 0609 are provided with coaxial arc notches 0611 to avoid the movement trajectory of the connecting rod 0607 and prevent the connecting rod 0607 from interfering with the first limiting plate 0608 and the second limiting plate 0609.
[0031] When the piston rod of the baffle cylinder 0605 extends, it pushes the connecting plate 0606 and the connecting rod 0607 to move, causing the positioning block 0604, the rotating shaft 0601, and the baffle 0602 to rotate around the axis of the rotating shaft 0601 until the positioning block 0604 contacts the pin 0610 of the limiting mechanism located above. At this time, the baffle 0602 is close to the material bag bracket 0201 and is in a baffle state, which can prevent the material bag 12 on the material bag bracket 0201 from sliding down. Figure 4 and Figure 8 As shown, when the piston rod of the material-stopping cylinder 0605 retracts, it pulls the connecting plate 0606 and the connecting rod 0607 to move, which in turn drives the positioning block 0604, the rotating shaft 0601, and the baffle 0602 to rotate around the axis of the rotating shaft 0601 until the piston rod of the material-stopping cylinder 0605 is fully retracted. At this time, the baffle 0602 moves away from the material bag bracket 0201 and is in the release state. The material bag 12 on the material bag bracket 0201 can continue to slide down, as... Figure 5 and Figures 9-11 As shown.
[0032] The bag-hanging device 10 includes a crankshaft 1001 and a rotary cylinder 1005. Five bag-tying cones 1002 are fixedly installed on the crankshaft 1001 and third bearing seats 1003 are installed at both ends. The third bearing seats 1003 are respectively fixedly installed on both sides of the frame 03. The rotary cylinder 1005 is fixedly connected to the frame 03. The rotary cylinder 1005 is connected to one end of the crankshaft 1001 through a coupling 1004. The rotary cylinder 1005 can drive the bag-tying cones 1002 to rotate so as to tie into the material bag 12 and hook the material bag to prevent the material bag 12 from continuing to slide down.
[0033] The bag-cutting device 11 includes a cylinder mounting bracket 1101, which is fixedly connected to both sides of the frame 03 and maintains an angle of 15-25 degrees with the horizontal. Another function of the cylinder mounting bracket 1101 is to limit the material bag support 0201 and control the flipping angle of the material bag support 0201 (the angle between the material bag support 0201 and the horizontal line) to not exceed 75 degrees and not less than 65 degrees, so as to facilitate material discharge. A rodless cylinder 1102 is installed below the cylinder mounting bracket 1101. A cutter mounting bracket 1103 is installed on the slider of the rodless cylinder 1102. A cutter 1104 is installed on the cutter mounting bracket 1103. The cutter 1104 can be moved by the rodless cylinder 1102 to cut the bottom of the material bag 12 so that the material in the material bag 12 can be discharged into the hopper 07.
[0034] The dust removal and ventilation device 04 includes a dust filter 0401 and an exhaust pipe 0402. The dust filter 0401 is fixedly connected to the frame 3 and located above the hopper 07. The exhaust pipe 0402 is fixedly connected to the dust filter 0401 and located above the dust filter 0401. The exhaust pipe 0402 is connected to an external fan, which can discharge the dust generated during the material discharge process.
[0035] The CIP cleaning device 05 includes a main water inlet pipe 0501, which is vertically fixed at one end of the frame 3 away from the roller conveyor line 01. Several branch water inlet pipes 0502 are horizontally fixedly connected to the main water inlet pipe 0501. The branch water inlet pipes 0502 are located inside the frame 3 and are fixedly connected to cleaning nozzles 0502. The inside of the equipment can be cleaned by connecting an external water source through the main water inlet pipe 0501 and using the cleaning nozzles 0502.
[0036] The working principle of this utility model is as follows: Figures 8-11As shown, after the material bag 12 slides into the material bag bracket 0201 via the roller conveyor line 01 and is blocked by the baffle 0602, the lifting cylinder 0302 drives the feed gate 0301 to fall and close the feed inlet. The rotating cylinder 1005 drives the crankshaft 1001 and the bag-tying cone 1002 to rotate, and the bag-tying cone 1002 pierces into the inside of the material bag 12. The blocking cylinder 0605 drives the baffle 0602 to rotate and move the baffle 0602 away from the material bag bracket 0201. The tilting cylinder 0205 drives the material bag bracket 0201 and the material bag 12 to tilt downwards until the material bag bracket 0201 contacts the cylinder mounting bracket 1101. The cutter 11... 04. Under the action of the rodless cylinder 1102, the bottom of the material bag 12 is slid and cut open. The material inside the material bag 12 falls into the funnel 07 and is conveyed to the material receiving end by the vacuum discharge machine 09. After the material inside the material bag 12 is discharged, the material bag flipping mechanism 02 moves in the opposite direction to make the material bag bracket 0201 return to the initial position. The bag hanging device 10 moves in the opposite direction to make the bag tying cone 1002 detach from the empty material bag and return to the initial position. The empty material bag slides into the waste bag collection device 08 and is pushed out and collected by the screw. The bag blocking and bag discharging device 06 moves in the opposite direction to make the baffle 0602 return to the material blocking state, and the next material bag unpacking and feeding process begins.
