After the discharge is completed, the missing gear 10 is disengaged from the first gear 11 and meshed with the second gear 19 to transport the support frame and perform the loading operation.

[0029] Example 2:

[0030] See also Figures 1 to 6 , the present invention provides a technical solution:

[0031] Two symmetrically arranged side panels 15 are fixedly installed on the top of the frame 1 near the material box 4. A first support frame 16 is slidably provided on the top of the side panel 15. A cross frame 17 is fixedly connected to the top of the first support frame 16. A slide groove 18 is provided on the surface of the cross frame 17.

[0032] The missing gear 10 is meshed with a second gear 19 on the side of the first gear 11. The bottom of the second gear 19 passes through the top frame 3 and is fixedly connected to a wheel disc 20. A protrusion is provided on the lower surface of the wheel disc 20 at a position offset from the axis. The protrusion is slidably arranged in the slide groove 18. The wheel disc 20 is used to rotate and drive the first support frame 16 to move back and forth on the side plate 15.

[0033] A second support frame 21 is provided on the inner side of the side panel 15 at one end opposite to the first support frame 16. One of the racks 22 is fixedly connected to the side of the first support frame 16. The bottom of the rack 22 is engaged with another rack 22 via a third gear 23. The other rack 22 is connected to the bottom of the second support frame 21. The first support frame 16 and the second support frame 21 are arranged alternately.

[0034] The surface of the side plate 15 is provided with a staggered guide groove 24, which is concave and has a transmission shaft 25 slidably provided therein. A mounting plate 26 is slidably provided above the transmission shaft 25. The mounting plate 26 is slidably connected to the side plate 15, and one end of the mounting plate 26 passes through the side plate 15 and is fixedly connected to the rack 22. The top of the transmission shaft 25 is fixedly connected to the second support frame 21.

[0035] The front side of the side panel 15 is fixedly connected to a material distribution plate 27, which is tilted and has its bottom close to the conveyor belt 2. The tops of the first support frame 16 and the second support frame 21 are rotatably connected to material distribution trays 28, respectively. When the material distribution trays 28 are close to the material box 4, they are located below the discharge port 8.

[0036] In this embodiment, when the first support frame 16 moves toward the material box 4, the second support frame 21 moves away from the material box 4, and vice versa, to ensure that one of the material trays 2828 is directly below the discharge port 88 to receive the material discharged from the discharge port 8;

[0037] In this embodiment, the flat material tray 28 and the material plate 27 can solve the problem of material accumulation on one side of the conveyor belt 2 during the loading process;

[0038] Example 3:

[0039] See also Figure 5 , the present invention provides a technical solution:

[0040] A swing arm 29 is fixedly connected to the outer wall of one side of the fabric tray 28. A through slot 30 is formed through the swing arm 29. One end of a pull rod 31 is slidably disposed in the through slot 30. The pull rod 31 is slidably connected to the first support frame 16 and the second support frame 21 respectively.

[0041] A blocking plate 32 is fixedly connected to one end of the bottom of the pull rod 31, and a blocking shaft 33 is fixedly connected to one side of the side plate 15. The end of the blocking shaft 33 abuts against the blocking plate 32, and the blocking shaft 33 is used to flip the fabric tray 28;

[0042] In this embodiment, the material tray 28 is turned over and dumped by preventing the shaft 33. Then, during the discharging operation of the short belt 6, the second gear 19 remains stationary, so that the turned material tray 28 can extend the material discharging time, which can improve the dumping effect of viscous materials.

[0043] The use method and advantages of the present invention: The automatic loading and unloading device for food processing has the following working process:

[0044] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 As shown:

[0045] S1: The granular food material to be processed is placed in advance in the material box 4. Due to the narrow bottom cavity 5 inside the material box 4, the material is gathered to the bottom by gravity, and the bottom contacts the short belt 6 in the material box 4. The top and bottom of the material box 4 are connected, so the material can be continuously replenished. The retaining shaft 7 can block the excess material during the rolling process of the end belt, so that the material discharge amount is uniform and the material is prevented from overflowing from above the short belt 6. The conveyor belt 2 is in the starting state and drives along the frame 1, ready to receive the material dropped from above;

[0046] S2: After the driving motor 9 is started, the output end drives the missing gear 10 to rotate, and the missing gear 10 alternately meshes with the gears on both sides. When the tooth portion of the missing gear 10 meshes with the first gear 11, the first gear 11 drives the worm 12 at the bottom to rotate, and the worm 12 meshes with the worm wheel 13 for transmission. The worm wheel 13 drives the short belt 6 to rotate through the pulley set 14, and the short belt 6 rolls forward, transporting the material at the bottom of the material box 4 to the discharge port 8, and finally discharged continuously from the discharge port 8 and falling on the cloth tray 28. When the tooth portion of the missing gear 10 disengages from the first gear 11, it directly meshes with the second gear 19 When the first support frame 16 moves, the rack 22 on its side engages with the third gear 23, driving the rack 22 on the other side to move in the opposite direction, thereby causing the second support frame 21 to reciprocate along the side plate 15 in the opposite direction to the first support frame 16. Because the two are linked by the third gear 23, "interlaced motion" is achieved, and the second support frame 21 drives the material falling from the material box 4 to be transported to the conveyor belt 2;

[0047] S3: After the material tray 28 moves to the bottom of the discharge port 8 along with the first support frame 16 and the second support frame 21 respectively, it receives the material; when the first support frame 16 and the second support frame 21 respectively drive the material tray 28 away from the discharge port 8 and move toward the material distribution plate 27, when approaching the blocking shaft 33, the blocking plate 32 is blocked by the blocking shaft 33, causing the pull rod 31 to compress the spring and move in the opposite direction of the movement of the support frame. During this process, the through slot 30 on the swing arm 29 slides relative to the pull rod 31, and the pull rod 31 drives the material distribution tray 28 to rotate ninety degrees around the connection between it and the support frame through the swing arm 29, forcing the swing arm 29 to drive the material distribution tray 28 to flip the tray opening downward around the top rotating shaft, and pour the received material onto the material distribution plate 27.

[0048] In the present invention, a short belt that rolls intermittently is installed in the material box, and the short belt is located at the bottom of the material. During a certain stroke, the short belt rolls to transport the material, and the amount of material transported outward is controlled by a stop shaft.

[0049] In the present invention, a first support frame and a second support frame are provided, and the second support frame is automatically raised and lowered by means of staggered guide grooves. When the two support frames approach each other, they stagger and avoid each other. In addition, the two material distribution trays are intermittently moved by the provided missing gears. When one of the material distribution trays is pouring the material for distribution, the other material distribution tray is loading the material, thereby improving the material loading and unloading operations.

[0050] In the present invention, by setting the swing arm and the blocking shaft, when one of the cloth trays is about to be clothed, the cloth tray is rotated so that the material inside is automatically dumped, and remains stationary for a period of time after dumping, which is convenient for dumping the sticky material and can improve the cloth effect.

[0051] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
