[0002] In industrial production, affected by factors such as storage conditions, material properties and quality control of raw material suppliers, powdered materials may contain lumps or foreign matter such as stones. If lumps and foreign matter are mixed into the product, it will cause problems such as product quality failure and food safety accidents.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.
[0037] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments:
[0038] like Figure 1-Figure 3 As shown, a feeding station includes a first vibrating screen 10, a feeding plate 20, a second vibrating screen 50 and at least one crushing device 30; wherein the first vibrating screen 10 is provided with a first upper discharge port 11 for discharging agglomerated materials and foreign matters and a first lower discharge port 12 for discharging powder; the feeding plate 20 is arranged below the first upper discharge port 11, and its downstream is inclined downward, and the feeding plate 20 can swing left and right relative to its material conveying direction; the crushing device 30 is arranged above the feeding plate 20, and is used to crush the agglomerated materials on the feeding plate 20; the second vibrating screen 50 is arranged below the end of the feeding plate 20, and is provided with a second upper discharge port 51 for discharging foreign matters and a second lower discharge port 52 for discharging powder.
[0039] In the feeding station provided in this embodiment, after the powder to be processed is input into the top opening of the first vibrating screen 10 through the feeding device 14 arranged above the first vibrating screen 10, the screened powder is discharged from the first lower discharge port 12, and the screened agglomerated materials and foreign matters are discharged from the first upper discharge port 11 to the upstream end of the conveying plate 20, and move downstream in the shaking of the conveying plate 20. During the movement, the agglomerated materials are crushed into powder by the crushing device 30, and discharged from the second lower discharge port 52 of the receiving second vibrating screen 50, and continue to be used for product processing, while the foreign matters are discharged from the second upper discharge port 51 of the second vibrating screen 50 after entering the second vibrating screen 50 and become waste.
[0040] The feeding station provided in this embodiment, after screening out the agglomerated materials and foreign matters through the first vibrating screen 10, crushes the agglomerated materials through the feeding plate 20 and the crushing device 30, and then screens the crushed materials and foreign matters through the second vibrating screen 50. It has the dual functions of separating foreign matters and crushing agglomerated materials, and can reduce manpower consumption and production costs while ensuring the quality of powder transportation.
[0041] In order to reduce dust pollution, in this embodiment, a fence 13 is provided between the first vibrating screen 10 and the feeding device 14 provided above it, so as to prevent a large amount of powder from spreading dust into the air during the falling process. In some embodiments, the fence 13 can be made of commonly used flexible materials such as rubber and cloth to reduce the complexity of the connection structure between the first vibrating screen 10 and the feeding device 14, and to prevent the connection structure between the two from loosening due to mechanical vibration during the production process.
[0042] Of course, in other embodiments, in order to further improve the environmental quality, the entire feeding station can be placed in a negative pressure environment, and a dust removal device can be provided to ensure the cleanliness of the exhaust gas.
[0043] In addition, in order to prevent the sieved agglomerated materials and foreign matter from sliding down from both sides of the feed conveyor plate 20, the present embodiment also provides baffles 21 on both sides of the feed conveyor plate 20. Figure 3 As shown, in this embodiment, a contracted conical opening is further provided at the downstream end of the feed plate 20 to ensure that the material can completely fall into the top opening of the second vibrating screen 50 .
[0044] Continue to refer Figure 1 As shown, in this embodiment, a hot air output device 40 is arranged between the first upper discharge port 11 and the crushing device 30. The hot air output device 40 faces the conveying plate 20 to provide hot air for the agglomerated material discharged from the first upper discharge port 11 to dry the agglomerated material formed due to moisture.
[0045] refer to Figure 2 As shown, in this embodiment, the crushing device 30 includes a support frame 33 and a rolling plate 31 disposed at the bottom end of the support frame 33. The upstream end of the rolling plate 31 is connected to the support frame 33, and the downstream end is inclined toward the feed plate 20. Preferably, the angle between the rolling plate 31 and the feed plate 20 is 3-20 degrees.
[0046] During use, after the agglomerated materials enter the bottom of the rolling plate 31, they gradually move downward due to friction, the shaking of the feed plate 20 and gravity until they are crushed by the rolling plate 31 and then separated from the bottom of the rolling plate 31. In some embodiments, in order to improve the crushing efficiency, an uneven pattern can be provided on the surface of the rolling plate 31.
[0047] Continue to refer Figure 2 As shown, in order to prevent foreign matter from being too hard and causing damage to the crushing device 30 and the feed plate 20, or foreign matter from being crushed and mixed into the powder due to excessive crushing force during the crushing process, the crushing device 30 provided in this embodiment is provided with an elastic structure so that the crushing plate 31 can move upward when subjected to greater pressure, avoiding being stuck between the crushing plate 31 and the feed plate 20, so that the foreign matter can be discharged smoothly.
[0048] Specifically, this embodiment provides two elastic structures:
[0049] First, the upstream end of the rolling plate 31 is rotatably connected to the support frame 33 through a hinge or other structure, and a torsion spring may be provided between the rolling plate 31 and the support frame 33, such as a spring sleeved on the rolling plate 31. Figure 3 Outside the rotating shaft 32 shown, the rolling plate 31 can swing downward to the lower limit position under the action of the torsion spring.
[0050] Secondly, an elastic member is disposed on the support frame 33 , and the crushing device 30 can be moved closer to or away from the feeding plate 20 (not shown) under the action of the elastic member.
[0051] Of course, in some embodiments, the two elastic structures may be used simultaneously to ensure smooth passage of large-sized foreign objects; or the two elastic structures may be mixed.
[0052] To ensure the crushing effect, in this embodiment, there are multiple crushing devices 30, and the multiple crushing devices 30 are arranged in sequence along the conveying direction of the conveying plate 20. Preferably, the distance between the multiple crushing devices 30 and the conveying plate 20 decreases from upstream to downstream.
[0053] Note: For the fixed connection methods described in this article, unless otherwise specified, existing fixed connection methods such as threaded connection, welding, and bonding can be used.
[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
