[0016] like Figure 1 As shown, this flip-type suction device sucks out the bottom bag in a stack of bags in the silo 2, and then flips the bag 180 degrees to place it at the bottom. Of course, the silo 2 here does not necessarily store bags, but other materials. As long as this method is used to discharge materials, this structure can be used.

[0017] like Figure 1 and Figure 2As shown, this flip-type bottom suction device includes a frame 1, a silo 2, a suction nozzle mechanism 4 and a power source 12. The silo 2 is arranged on a silo support 20, and the silo support 20 is installed on the frame 1. The suction nozzle mechanism 4 is located below the silo 2. The suction nozzle mechanism 4 includes a suction nozzle assembly and a suction nozzle seat 40, and the suction nozzle assembly is installed on the suction nozzle seat 40. A stack of bags is placed in the silo 2, and the silo support 20 has a window 21. The suction nozzle mechanism 4 sucks the bags out from the window 21, and then moves down and flips.

[0018] In order to enable the nozzle mechanism 4 to move up and down and to flip, Figure 1 As shown, a vertical guide rail 9 is installed on the frame 1. Figure 2 As shown, a lifting slide 6 is slidably provided on the vertical guide rail 9, and the power source 12 can drive the lifting slide 6 to slide on the vertical guide rail 9; a rotatable shaft 5 is installed on the lifting slide 6, and the shaft 5 is connected to the nozzle holder 40; in addition, a swingable guide plate 8 is installed on the frame 1 (the upper end of the guide plate 8 is hinged on the frame 1 and can swing around the hinge point 84), as shown in FIG. Figure 3 As shown, the guide plate 8 has a guide groove, which is composed of a straight upper section 81, a curved middle section 82 and a straight lower section 83, wherein the straight upper section 81 and the straight lower section 83 are located on a straight line (allowing the nozzle mechanism 4 to move up and down in a straight line), and a guide column 80 is connected to the guide plate 8, the guide column 80 is located on one side of the curved middle section 82, and the guide column 80 is located on the connecting line of the straight upper section 81 and the straight lower section 83 (allowing the flip plate 7 to remain vertical); as shown in FIG. Figure 5 As shown, the rotating shaft 5 is connected to a flip plate 7 , the flip plate 7 has a long slot 70 , and the guide column 80 is located in the long slot 70 of the flip plate 7 ; in addition, the inner end of the rotating shaft 5 is located in the guide slot of the guide plate 8 .

[0019] The working principle of this flip-type down-suction device is introduced in detail below.

[0020] like Figure 2 As shown, when the power source 12 drives the lifting slide 6 to slide on the vertical guide rail 9, since the rotating shaft 5 and the suction nozzle mechanism 4 are both installed on the lifting slide 6, the rotating shaft 5 and the suction nozzle mechanism 4 also move up and down; Figure 5As shown, when the lifting slide 6 drives the rotating shaft 5 to move downward, the flip plate 7 connected to the rotating shaft 5 also moves downward synchronously. Since the inner end of the rotating shaft 5 is located in the guide groove of the guide plate 8, when the inner end of the rotating shaft 5 is located at the straight upper section 81 of the guide groove, the rotating shaft 5 and the flip plate 7 can move downward in a straight line without rotating (the reverse direction is also a linear motion, allowing the suction nozzle to approach the bag with a vertical motion trajectory, so that the suction nozzle can be adsorbed on the bag from the front); when the rotating shaft 5 gradually comes to the curved middle section 82 of the guide groove, the rotating shaft 5 and the flip plate 7 gradually rotate, and since the suction nozzle mechanism 4 is installed on the rotating shaft 5, the suction nozzle mechanism 4 also gradually rotates; when the rotating shaft 5 comes to the straight lower section 83 of the guide groove, the rotating shaft 5 and the flip plate 7 are completely 1 When the bag is turned over by 80°, the suction nozzle mechanism 4 is also completely turned over; when the rotating shaft 5 is in the straight lower section 83 of the guide groove, the rotating shaft 5 and the turning plate 7 can move downward in a straight line, so that the suction nozzle mechanism 4 sucks the bag and moves downward in a horizontal posture, and puts the bag down horizontally; because the lifting slide 6 is straight up and down on the vertical guide rail 9, the movement trajectory of the rotating shaft 5 is also straight up and down, and because the rotating shaft 5 moves in the guide groove of the guide plate 8, and the guide groove has a curved middle section 82, in order to make the movement trajectory of the rotating shaft 5 straight up and down, the guide plate 8 can only be rotated so that the rotating shaft 5 can move up and down along the vertical line, so that the rotating shaft 5 can move in the guide groove and ensure that the movement trajectory of the rotating shaft 5 is straight up and down. The flip-type lower suction device with this structure only needs one power source to drive the suction nozzle mechanism 4 to move up and down and turn over, so the speed is faster, the structure is more stable, and the cost is lower.

[0021] In order to enable the power source 12 to drive the lifting slide 6 to move, as Figure 1 As shown, a rotatable sprocket 11 is mounted on the frame 1, a pull rod 10 is hinged at an eccentric position of the sprocket 11, the other end of the pull rod 10 is hinged to the lifting slide 6, and the output end of the power source 12 is connected to the sprocket 11 through a chain. Driven by the power source 12, the chain drives the sprocket 11 to rotate, and the sprocket 11 drives the lifting slide 6 to move up and down through the pull rod 10. Of course, the lifting slide 6 can also be driven to move through other transmission structures.

[0022] In order to reduce the friction between the inner end of the rotating shaft 5 and the guide groove of the guide plate 8, a roller 50 (the roller 50 is a bearing) is connected to the inner end of the rotating shaft 5, and the roller 50 is located in the guide groove of the guide plate 8. Since the roller 50 can rotate, the friction is smaller and the noise is lower when the guide groove of the guide plate 8 moves.

[0023] In order to install the rotating shaft 5, as Figure 1 As shown, a bearing seat 60 is installed on the frame 1, and the rotating shaft 5 is installed in the bearing seat 60 through a bearing.

[0024] like Figure 1As shown, the silo 2 has two, and the corresponding suction nozzle mechanisms 4 have two, each suction nozzle mechanism 4 has a corresponding shaft 5, a guide plate 8 and a flip plate 7, and the two shafts 5 corresponding to the two suction nozzle mechanisms 4 are installed on a lifting slide 6. Such a power source 12 can drive the two suction nozzle mechanisms 4 to work, and the production efficiency is greatly improved without increasing the cost.

[0025] Finally, it is worth mentioning that Figure 3 As shown, the suction nozzle assembly includes a suction nozzle 42 and a suction rod 41. The suction nozzle 42 is installed on the suction rod 41, and the suction rod 41 is installed on the suction nozzle seat 40 and connected to the air source.
