[0035] Please refer to Figures 1 to 4 The utility model discloses a multi-station hopper feeding device 100, including frame 1, hopper 2, lifting assembly 3 and working table 4. Frame 1 includes the working layer 11 and the feeding layer 12 set up, hopper 2 sets up in feeding layer 12, working table 4 sets up in working layer 11, lifting assembly 3 is used for linking working layer 11 and feeding layer 12, to transport the material in hopper 2 to working table 4 and unloads.

[0036] Hopper 2 is at least provided with three, and includes first feeding hopper 21, second feeding hopper 22 and discharging hopper 23 placed in feeding layer 12 in sequence. Lifting assembly 3 is same in number with hopper 2 and corresponds in sequence. In this embodiment, hopper 2 is provided with five, and includes first feeding hopper 21, second feeding hopper 22, discharging hopper 23, third feeding hopper 24 and fourth feeding hopper 25 set in sequence, and lifting assembly 3 is also provided with five in sequence, to transport the material in corresponding feeding hopper separately.

[0037] The material includes a tray 26 for carrying the material. The hopper 2 is provided with a conveying assembly 27, and the tray 26 is conveyed to the opposite position of the lifting assembly 3 by the conveying assembly 27 and is driven to ascend or descend by the lifting assembly 3. Preferably, the lower hopper 23 is arranged at the middle position of the plurality of upper hoppers to ensure that each tray 26 can be recycled and stored.

[0038] Specifically, the conveying assembly 27 includes two parallel conveying belts 271, the lifting assembly 3 includes a lifting rail 31 extending along the height direction of the multi-station hopper feeding device 100 and a driving part 32 located at least partially between the two conveying belts 271, and the driving part 32 is configured to be movable up and down along the lifting rail 31 to drive and lift the tray 26 to the working layer 11 after the tray 26 is conveyed to the directly above of the driving part 32 by the two conveying belts 271. When the material on the tray 26 is emptied, the tray 26 is transported to the lower hopper 23 by the lifting assembly 3 to complete the recycling of the tray 26. Therefore, in the utility model, the material in the plurality of upper hoppers can be unloaded, and after the unloading is completed, it can be recycled to the lower hopper 23, which is simple and flexible to operate.

[0039] The workbench 4 is arranged on the working layer 11 and is configured to be slidable relative to the rack 1 to be sequentially opposite to each hopper 2 and receive the material transported from the hopper 2.

[0040] The number of the workbench 4 is less than the number of the hopper 2. Therefore, the workbench 4 is provided with at least two, one of which is allowed to slide at a position corresponding to the first upper hopper 21 and the lower hopper 23, and the other is allowed to slide at a position corresponding to the second upper hopper 22 and the lower hopper 23.

[0041] In the embodiment, the workbench 4 is a first workbench 41, a second workbench 42 and a third workbench 43 connected to each other. The first workbench 41 is selectively slidable at positions corresponding to the first upper hopper 21, the second upper hopper 22 and the lower hopper 23; the second workbench 42 is selectively slidable at positions corresponding to the second upper hopper 22, the lower hopper 23 and the third upper hopper 24; and the third workbench 43 is selectively slidable at positions corresponding to the lower hopper 23, the third upper hopper 24 and the fourth upper hopper 25. Therefore, the workbench 4 can receive the material of at least two upper hoppers at the same time to facilitate subsequent mixing.

The driving belt 113 can be driven by the driving motor 112 to drive the driven block 47 to move synchronously. Of course, the movement of the workbench 4 relative to the sliding guide rail 111 can also be realized through the combination of a screw rod and the driving motor 112.

[0044] The workbench 4 is correspondingly provided with a limiting device 44. When the workbench 4 slides to be in alignment with the first upper material bin 21 or the second upper material bin 22, the tray 26 is limited by the limiting device 44 to be fixed on the workbench 4.

By providing the limiting device 44, the unloading of the material and the tray is more facilitated.

[0045] Specifically, the limiting device 44 includes a first limiting device 441 and an activatable second limiting device 442 which are independent of each other. In the height direction of the multi-station material bin feeding device 100, the first limiting device 441 is used to limit the upper surface of the tray 26, and the second limiting device 442 is used to limit the lower surface of the tray 26. Therefore, through the clamping of the first limiting device 441 and the second limiting device 442 on the tray 26, the tray 26 can be stably fixed on the workbench 4 to facilitate unloading.

[0046] The workbench 4 is provided with an opening 40 for the tray 26 to pass through. The first limiting device 441 includes a baffle 4411 extending partially into the opening 40, which is in abutment with the upper surface of the tray 26 to limit the upward movement of the tray 26. In this way, the tray 26 can always stop at the designated position and be fixed on the workbench 4.

[0047] The second limiting device 442 comprises a supporting plate 4421 capable of supporting the tray 26, and a driving device 4422 connected with the supporting plate 4421, wherein the driving device 4422 is configured to drive the supporting plate 4421 to move towards the shaft center of the opening 40, so as to support the lower surface of the tray 26. Preferably, the driving device 4422 is a pneumatic cylinder, which can be driven to support or leave the lower surface of the tray 26. Preferably, the first limiting device 441 and the second limiting device are both provided with a plurality of devices, so as to fix the tray 26 at each angle.

[0048] The workbench 4 is further provided with an outwardly extending connecting plate 46, which is used to be connected with a drag chain 5, and the drag chain 5 is provided with a cable.

[0049] In conclusion, the multi-station material bin feeding device 100 of the present application is provided with the upper feeding bin and the lower feeding bin 23 arranged in sequence, and the workbench 4 is slidable along the arrangement direction of the upper feeding bin and the lower feeding bin 23, so that the feeding bin can be fed and the tray 26 can be unloaded in the alignment process of the workbench 4, the upper feeding bin and the lower feeding bin 23, without relying on the grabbing equipment, and the present application has practicality.

[0050] The above description is only the preferred embodiments of the present application, and is not used to limit the present application, and it should be pointed out that, for ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and modifications can be made, and these improvements and modifications should be regarded as the protection scope of the present application.
