Description

Technical Field

[0001] The utility model relates to the technical field of spiral feeding, and more particularly to a spiral powder feeding device. Background Art

[0002] In the prior art, a screw conveying mechanism is often used to convey powder to achieve powder refilling operation. When the moisture content of the powder is high, lumps often appear between the spiral blades and the shell. When there are many lumps, the entire device is prone to jamming, making the entire device unable to operate normally. At the same time, when there are many lumps, the powder will be thrown out of the opening on the shell, resulting in powder waste.

[0003] Therefore, during the material feeding process, the lumps are often removed manually after a period of time. This treatment method greatly affects the processing efficiency and increases the processing cost. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a spiral powder feeding device, which can effectively clean the lumps without stopping the machine, avoid the machine jamming, greatly reduce the production and processing costs, and improve the processing efficiency;

[0007] The elastic cleaning components are in multiple groups and are arranged along the conveying direction of the spiral conveying component; the elastic cleaning components are arranged between the inner side surface of the box body and the spiral conveying component.

[0008] In some possible implementations, the elastic cleaning assembly includes an elastic support mounted on the inner side of the box body, and a cutting plate mounted on the elastic support.

[0009] In some possible implementations, the elastic support is in a strip-shaped structure, and the length is equal to the length of the cutting plate.

[0010] In some possible implementations, the cross-section of the cutting plate is an arc-shaped structure, and the arc of the arc-shaped structure is arranged on a side close to the rubber support.

[0012] In some possible embodiments, the box body includes a bottom plate, two groups of side plates arranged in parallel and mounted on the bottom plate, an end plate mounted on the bottom plate and connected to the ends of the side plates, and a top plate arranged on the two groups of side plates; a gap is formed between the two groups of top plates; and the elastic cleaning assembly is mounted on the side plates.

[0013] In some possible implementations, the top plate and the side plates are of equal length along the conveying direction of the spiral conveyor, and a connection between the top plate and the side plates is in an arc transition.

[0014] In some possible implementations, the spiral conveying assembly includes a rotating shaft rotatably mounted in the box body, a spiral blade sleeved on the outside of the rotating shaft, and a driving motor mounted on the outside of the end plate and transmission-connected to the rotating shaft.

[0026] The utility model is described in detail below.

[0027] like Figure 1-Figure 4 As shown:

[0028] A spiral powder feeding device for conveying and feeding powder materials; comprising a box body 1, a spiral conveying assembly 2 rotatably mounted on the box body 1, and an elastic cleaning assembly 3 mounted in the box body 1 and used to clean lumps formed during the conveying process;

[0029] The elastic cleaning components 3 are multiple groups and are arranged along the conveying direction of the spiral conveying component 2; the elastic cleaning components 3 are arranged between the inner side surface of the box body 1 and the spiral conveying component 2.

[0030] Specifically, the box body 1 is provided with a conveying cavity, an inlet 15 provided at the top of the box body 1 and located on the side of the powder input end, and a discharge port provided at the bottom of the box body 1 and located at the powder output end. The spiral conveying assembly 2 is located in the installation cavity and conveys the powder entering the conveying cavity from the inlet 15 to the discharge port. The elastic cleaning assembly 3 is subjected to the force exerted by the powder on it during the conveying process, causing it to transform from an initial state to a stretched deformed state.

[0031] Under the elastic force combined with the strong mechanical vibration of the box body 1 during the transportation process, the lumps in the box body 1 are squeezed and cut, thereby reducing the accumulation of lumps during the transportation process and avoiding the situation where the entire device cannot be used normally due to the large amount of lumps accumulated after long-term use;

[0032] The utility model has the advantages of simple structure and strong practicability, and does not require manual cleaning of lumps, thereby greatly improving work efficiency and reducing construction costs.

[0033] In some possible implementations, in order to effectively squeeze and cut the agglomerates through the elastic component during the conveying process to avoid long-term accumulation of agglomerates;

[0034] The elastic cleaning assembly 3 includes an elastic support 31 installed on the inner side of the box body 1, and a cutting plate 32 installed on the elastic support 31; during the conveying process, the powder conveyed from the input end to the output end will squeeze the elastic support 31, causing it to deform after being subjected to the force; the deformed elastic support 31 will provide elastic force to the cutting plate 32 under the elastic force, thereby squeezing and cutting the lumps accumulated on the side of the box body 1 to disperse them, and the dispersed lumps will be conveyed from the input end to the output end under the drive of the spiral conveying assembly 2.

[0035] Furthermore, the elastic support 31 is in a strip-shaped structure, and its length is equal to that of the cutting plate 32, so that there is no gap between the cutting plate 32 and the inner side of the box body 1, thereby preventing powder from entering the gap and causing the elastic cleaning component 3 to be unable to effectively clean the lumps.

[0036] In some possible implementations, the cross-section of the cutting plate 32 is an arc-shaped structure, and the arc of the arc-shaped structure is arranged on a side close to the rubber support;

[0037] The cutting plate 32 is mounted on a rubber support on the side away from the arc structure. The arc structure prevents the dispersed agglomerates from remaining on the cutting plate 32 and allows them to be effectively transported in the transport cavity.

[0038] In some possible implementations, such as Figure 1 As shown, the cutting plate 32 is tilted and the angle formed with the axis direction of the spiral conveying assembly 2 is A, which is an acute angle;

[0039] Specifically, A is 30°-60°.

[0040] In some possible embodiments, the box body 1 includes a bottom plate 11, two sets of side plates 12 arranged in parallel and mounted on the bottom plate 11, end plates 13 mounted on the bottom plate 11 and connected to the ends of the side plates 12, and a top plate 14 mounted on the two sets of side plates 12; a gap is formed between the two sets of top plates 14; the elastic cleaning assembly 3 is mounted on the side plates 12;

[0041] Specifically, the bottom plate 11, the two sets of side plates 12, and the two sets of end plates 13 cooperate to form a conveying chamber, and the spiral conveying assembly 2 is in transmission cooperation with the two sets of end plates 13; the elastic support 31 is installed on the side of the two sets of side plates 12 that are close to each other; a gap is formed between the cutting plate 32 and the spiral conveying assembly 2; the top plate 14 is installed on the side of the side plate 12 away from the bottom plate 11 and is arranged one-to-one with the side plate 12, thereby preventing the powder from being thrown out of the top of the box body 1 during the conveying process, causing waste;

[0042] Specifically, the top plate 14 and the side plate 12 have the same length along the conveying direction of the spiral conveyor, and the connection between the top plate 14 and the side plate 12 is in an arc transition.

[0043] In some possible embodiments, the spiral conveying assembly 2 includes a rotating shaft 21 rotatably installed in the box body 1, a spiral blade 22 sleeved on the outside of the rotating shaft 21, and a driving motor installed on the outside of the end plate 13 and transmission connected to the rotating shaft 21.

[0044] The two ends of the rotating shaft 21 are rotatably matched with the two groups of end plates 13. Bearings are provided on the two groups of end plates 13, and the two ends of the rotating shaft 21 are connected to the bearings. The drive motor is provided on the end plate 13 on the side close to the inlet 15 and is located on the outside of the box body 1. The drive motor is connected to the rotating shaft 21 through a coupling to drive the rotating shaft 21 to rotate around its axis, thereby driving the rotation of the spiral blade 22, and thus effectively conveying the powder located in the conveying chamber.

[0045] A feeding hopper 4 is provided on the top plate 14 , communicating with the gap and located at the powder input end. The feeding hopper 4 is communicated with the inlet 15 .

[0046] The present invention is not limited to the aforementioned specific embodiments, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
