[0022] Specific implementation method (Note: The green font part below is the content added relative to the claims)

[0023] The following is a detailed description of an embodiment of the present invention. This embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation method and a specific operation process are given, but the protection scope of the present invention is not limited to the following embodiment.

[0024] See also Figures 1 to 4 The present embodiment discloses a flip feeding mechanism of a blueberry weighing and packaging machine, which comprises a feeding mechanism 2 and a weighing mechanism 3 installed on a frame 1, wherein the feeding mechanism 2 is located above the weighing mechanism 3, and a feeding frame 4 of the feeding mechanism 2 is rotatably installed on the frame 1 through a rotating shaft 5 extending in the left-right direction, and the rotating shaft 5 is rotatably installed on the frame 1 and is located behind the weighing mechanism 3, and a rear end of the feeding frame 4 is rotatably supported by a driving shaft 6 extending in the left-right direction, and the driving shaft 6 is fixedly connected to the rotating shaft 5 through a connecting member 7, and a driving mechanism is also provided on the frame 1, which drives the driving shaft 6 to swing back and forth around the axis of the rotating shaft 5 through the driving mechanism, and the driving shaft 6 drives the feeding frame 4 to flip back and forth around the rotating shaft 5.

[0025] The driving mechanism preferably adopts a cylinder 8, the bottom of the cylinder body of the cylinder 8 is rotatably mounted on the frame 1, and the top of the piston rod 9 of the cylinder 8 is rotatably mounted on the driving shaft 6. The piston rod 9 of the cylinder 8 is extended and retracted, thereby driving the driving shaft 6 to swing back and forth around the axis of the rotating shaft 5. Considering that the driving shaft 6 is long, the driving mechanism includes a plurality of cylinders 8, and the plurality of cylinders 8 are arranged at intervals along the left and right directions, and the plurality of cylinders 8 drive the driving shaft 6 to swing back and forth together.

[0026] A first bayonet 10 is provided at the bottom of the feed rack 4, and the bottom of the feed rack 4 is rotatably supported on the rotating shaft 5 through the first bayonet 10. The first bayonet 10 is a U-shaped hole with an opening facing downward, and the upper section of the first bayonet 10 is semicircular. The inner wall of the first bayonet 10 is provided with a first wear-resistant layer, and contacts with the rotating shaft 5 through the first wear-resistant layer. A second bayonet 11 is provided at the rear end of the feed rack 4, and the rear end of the feed rack 4 is rotatably supported on the driving shaft 6 through the second bayonet 11. The second bayonet 11 is a U-shaped hole with an opening facing backward, and the front section of the second bayonet 11 is semicircular. The inner wall of the second bayonet 11 is provided with a second wear-resistant layer, and contacts with the driving shaft 6 through the second wear-resistant layer. The provision of the first wear-resistant layer and the second wear-resistant layer can effectively reduce the wear between the feed rack 4 and the rotating shaft 5, and between the feed rack 4 and the driving shaft 6, thereby extending the service life of the mechanism.

[0027] The connecting member 7 includes a rotating connecting plate 12 and a pushing connecting plate 13. The front end of the rotating connecting plate 12 is fixed on the rotating shaft 5, and the rear end of the pushing connecting plate 13 is fixed on the pushing shaft 6. The rear end of the rotating connecting plate 12 overlaps with the front end of the pushing connecting plate 13. A waist-shaped hole 14 is opened on the overlapping section of the rotating connecting plate 12, and a mounting hole is opened on the overlapping section of the pushing connecting plate 13. The rotating connecting plate 12 and the pushing connecting plate 13 are connected together by bolts passing through the waist-shaped hole 14 and the mounting hole in sequence and tightening the nut. In this embodiment, the connecting member 7 is designed to be composed of two parts, the rotating connecting plate 12 and the pushing connecting plate 13, and the rotating connecting plate 12 and the pushing connecting plate 13 adopt this connection method. The overlapping length of the rotating connecting plate 12 and the pushing connecting plate 13 can be adjusted to a certain extent, thereby adjusting the overall length of the entire connecting member 7, which is convenient for conveniently adjusting the overall length of the entire connecting member 7 according to the distance between the two bayonet ports, and the position accuracy requirements of the two bayonet ports of the feed rack 4 are not high.

[0028] A first anti-rotation groove 15 extending in the axial direction is formed on the outer wall of the rotating shaft 5, a first through hole is formed on the front end of the rotating connecting plate 12, a first anti-rotation protrusion 16 is provided inside the first through hole, the rotating connecting plate 12 is sleeved on the rotating shaft 5 through the first through hole, and the first anti-rotation protrusion 16 is embedded in the first anti-rotation groove 15 to prevent the rotating connecting plate 12 and the rotating shaft 5 from rotating relative to each other. A second anti-rotation groove 17 extending in the axial direction is formed on the outer wall of the driving shaft 6, a second through hole is formed on the rear end of the driving connecting plate 13, a second anti-rotation protrusion 18 is provided inside the second through hole, the driving connecting plate 13 is sleeved on the driving shaft 6 through the second through hole, and the second anti-rotation protrusion 18 is embedded in the second anti-rotation groove 17 to prevent the driving connecting plate 13 and the driving shaft 6 from rotating relative to each other. Anti-rotation structures are respectively arranged between the rotating connecting plate 12 and the rotating shaft 5, and between the pushing connecting plate 13 and the pushing shaft 6, so that the pushing shaft 6 and the rotating shaft 5 can be connected into a whole. In the process of the cylinder 8 extending and retracting to drive the pushing shaft 6 to swing, the rotating shaft 5 will also rotate accordingly, thereby providing assistance for the back and forth flipping of the feeding rack 4, which helps the flipping movement of the feeding rack 4, thereby ensuring the smoothness of the flipping movement of the feeding rack 4.

[0029] When the blueberry weighing and packaging machine is working normally, the piston rod 9 of the cylinder 8 is in an extended state. At this time, the feeding frame 4 of the feeding mechanism 2 is in a horizontal state. The multiple side-by-side feeding units of the feeding mechanism 2 respectively supply blueberries to the multiple side-by-side weighing units of the weighing mechanism 3. Then, after being weighed by each weighing unit, the blueberries fall into the downstream blueberry packaging box for packaging.

[0030] When the weighing mechanism 3 needs to be repaired, the piston rod 9 of the control cylinder 8 is retracted, and the piston rod 9 of the cylinder 8 pulls the push shaft 6 to rotate around the axis of the rotating shaft 5, and the push shaft 6 then pulls the rear end of the feeding rack 4 downward, so that the feeding rack 4 flips around the axis of the rotating shaft 5, and the front end of the feeding rack 4 flips upward, thereby flipping the entire feeding mechanism 2 upward, leaving an operating space between the feeding mechanism 2 and the weighing mechanism 3, and the weighing mechanism 3 can be easily repaired. The weighing mechanism 3 can be repaired without manually disassembling the feeding mechanism 2, which solves the problem of difficult on-site repair of the weighing mechanism 3 and makes the repair of the weighing mechanism 3 convenient and quick. After the repair is completed, the piston rod 9 of the control cylinder 8 is extended, and the piston rod 9 of the cylinder 8 pushes the push shaft 6 upward to rotate in the opposite direction around the axis of the rotating shaft 5, and the push shaft 6 pushes the rear end of the feeding rack 4 upward again, so that the feeding rack 4 reversely flips and resets.

[0031] When the feeding mechanism 2 itself needs to be inspected or replaced, the entire feeding rack 4 can be lifted slightly upward first, so that the feeding rack 4 can be separated from the rotating shaft 5 as a whole, and then the feeding rack 4 can be pulled slightly forward and upward to make the entire feeding rack 4 separate from the driving shaft 6, so that the entire feeding mechanism 2 can be completely disassembled, and the new feeding mechanism 2 can be replaced by the reverse operation, thereby realizing the quick operation of inspecting the feeding mechanism 2 itself or replacing the whole.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
