DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0020] As Figures 1 to 3 shown, this specific embodiment provides a mixing device, which includes a frame 1 and a plurality of raw material storage bins 11. A vacuum feeding machine 2 is installed on the frame 1. The vacuum feeding machine 2 is connected to the raw material storage bin 11 through a feeding pipe 21. A flow sensor 22 signal-connected to the vacuum feeding machine 2 is provided on the feeding pipe 21. A mixing mechanism 3 is installed below the vacuum feeding machine 2. The feeding port of the mixing mechanism 3 is aligned with the discharging port of the vacuum feeding machine 2. A storage bucket 43 is placed below the discharging port of the mixing mechanism 3.

[0021] When the mixing device is working, the flow sensor 22 is used to monitor in real time the amount of raw materials transported by the feeding pipe 21 to the vacuum feeding machine 2, so that the vacuum feeding machine 2 can extract the raw materials in each raw material storage bin 11 into the mixing mechanism 3 according to the set proportion for mixing. After that, the mixing mechanism 3 discharges the mixed raw materials into the storage bucket 43. Therefore, it is not necessary to manually pre-import various materials into the mixing device according to the proportion, and various raw materials can be automatically mixed according to the proportion. Thus, when a large number of materials need to be continuously mixed, the labor can be effectively reduced and the production efficiency can be improved. At the same time, since the operator does not need to directly contact or approach the mixing mechanism 3 when mixing the raw materials, the occurrence of safety accidents can be effectively reduced.

[0022] In this embodiment, a discharging hopper 4 is installed below the discharging port of the mixing mechanism 3. A pneumatic discharging valve 41 is installed at the discharging port of the discharging hopper 4. A conveying device 42 for sequentially moving a plurality of storage buckets 43 to the position below the discharging port of the discharging hopper 4 is installed below the discharging hopper 4.

[0023] When the storage bucket 43 is filled or loaded with the mixed materials in portions, the conveying device 42 can move the storage bucket 43 to the target position (such as a storage point, a processing station, etc.), and at the same time, move the next empty storage bucket 43 to the position below the discharging hopper 4. The setting of the discharging hopper 4 can effectively prevent the materials from dripping onto the conveying device 42 or the edge of the storage bucket 43 when the conveying device moves the storage bucket 43.

[0024] In this embodiment, the bottom of the raw material storage bin 11 is a hopper-shaped discharging port, and the feeding pipe 21 is connected to the hopper-shaped discharging port; so that the vacuum feeding machine 2 can more stably extract the raw materials in the raw material storage bin 11.

[0025] In this embodiment, the mixing mechanism 3 includes a support frame 31. The support frame 31 is provided with an annular slide rail 32. A sliding drum 33 is arranged on the annular slide rail 32. A material inlet and outlet 34 is arranged at the peripheral wall position of the drum 33. The material inlet and outlet 34 is located below the vacuum feeding machine 2 and above the discharge hopper 4. A driving tooth 331 is arranged on the outer periphery of the drum 33. A first motor 35 is installed on the support frame 31. The first motor 35 drives a gear 351 that meshes with the driving tooth 331.

[0026] The first motor 35 drives the gear 351 to rotate. The gear 351 drives the drum 33 to rotate through the driving tooth 331, so that the material inlet and outlet 34 of the drum 33 moves to face the discharge port of the vacuum feeding machine 2. Thereafter, the vacuum feeding machine 2 extracts the raw materials in each raw material storage box 11 according to the set proportion and feeds them into the drum 33 from the material inlet and outlet 34. Thereafter, the first motor 35 drives the gear 351 to drive the drum 33 to rotate left and right reciprocally, so as to drive the raw materials in the drum 33 to tumble, thereby realizing the mixing of the raw materials. After the mixing is completed, the first motor 35 drives the gear 351 to drive the drum 33 to rotate 180 degrees, so that the material inlet and outlet 34 of the drum 33 moves to face the discharge hopper 4. At this time, the mixture in the drum 33 is poured from the material inlet and outlet 34 into the discharge hopper 4.

[0027] In this embodiment, a second motor 36 is installed on the support frame 31. The second motor 36 drives a drive shaft 361. The drive shaft 361 extends into the drum 33 from the center of the drum 33. A material stirring rod 362 that is eccentric to the drum 33 is arranged on the drive shaft 361.

[0028] After the vacuum feeding machine 2 extracts the raw materials in each raw material storage box 11 according to the set proportion and feeds them into the drum 33 from the material inlet and outlet 34, the second motor 36 drives the drive shaft 361 to rotate. The drive shaft 361 drives the material stirring rod 362 to stir the materials in the drum 33, so that various raw materials can be mixed more evenly.

[0029] In this embodiment, several vacuum feeding machines 2 that are independently connected to each raw material storage box 11 are arranged above the drum 33. A guide plate 37 is arranged between the drum 33 and the discharge port of the vacuum feeding machine 2.

[0030] By arranging several vacuum feeding machines 2 that are independently connected to each raw material storage box 11, it is avoided that other raw materials are doped when the vacuum feeding machine 2 extracts the raw materials into the drum 33, thereby affecting the accuracy of the proportion of each raw material.

[0031] In this embodiment, the mixing mechanism 3 further includes a weighing device 38. The support frame 31 is installed on the weighing device 38; so as to realize weighing when the vacuum feeding machine 2 extracts each raw material into the drum 33, thereby further ensuring the accuracy of the proportion of each raw material.
