DETAILED DESCRIPTION

[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0028] Embodiment 1

[0029] like Figure 1-Figure 3 As shown, a non-metallic impeller includes a rotating shaft 1, a sleeve 2, a side plate 3 and a plurality of blades 4; the rotating shaft 1 is made of metal material and is used to connect with the driving device. The metal material can ensure the strength of the non-metallic impeller. The rotating shaft 1 has a working section 101 located inside the cylinder of the star feeder. The sleeve 2, the side plate 3 and the blades 4 are all located inside the star feeder and are in direct contact with the material. The three are made of non-metallic materials, wherein the sleeve 2 is installed on the outer periphery of the working section 101, the blades 4 are installed on the outer peripheral surface of the sleeve 2 and are radially extended, and the two side plates 3 are located at both ends of the sleeve 2. Two adjacent blades 4, the two side plates 3 and the outer peripheral surface of the sleeve 2 form a push cavity 5. When the star feeder is working, the material falls in the direction perpendicular to the rotating shaft 1, and the rotating shaft 1 rotates at the same time. The material enters different push cavities 5 in turn. As the rotating shaft 1 rotates, the material in the push cavity 5 is transported to the discharge port at the bottom and discharged from the discharge port.

[0030] The blade 4, sleeve 2 and side plate 3 in this embodiment can be an integrated structure, and then the sleeve 2 is fixed to the rotating shaft 1. In order to further reduce the maintenance cost, this embodiment preferably connects the blade 4, sleeve 2 and side plate 3 detachably, so as to facilitate the disassembly and independent replacement of parts.

[0031] Assembly of blade 4 and sleeve 2:

[0032] like Figure 4 and Figure 5As shown, the outer circumference of the sleeve 2 is provided with a plurality of T-slots 201, and the blade 4 has a T-slot 401 suitable for being inserted into the T-slot 201, and the T-slot 201 at least extends to one axial end of the sleeve 2. When installing, the blade 4 can be inserted from one end of the T-slot 201. The T-shaped structure of the T-slot 201 can prevent the blade 4 from being radially dislodged. In this embodiment, the cross section of the T-slot 201 is T-shaped. Those skilled in the art should understand that the cross section of the T-slot 201 can also be an inverted triangle, a semicircle or other irregular shapes. The length of the T-slot 401 can be less than or equal to the axial length of the sleeve 2.

[0033] When the length of the T-shaped bar 401 is less than the axial length of the sleeve 2, the gap between the blade 4 and the sleeve 2 needs to be filled by the special-shaped design of the sleeve 2 or the side plate 3 to ensure the mutual independence of adjacent pusher cavities 5. In this embodiment, the axial length of the T-shaped bar 401 is preferably the same as that of the sleeve 2, so that the structure of each component is more regular and the processing is simpler.

[0034] Assembly of sleeve 2 and shaft 1:

[0035] The shaft sleeve 2 and the rotating shaft 1 may be connected by screws. In other optional implementations, the shaft sleeve 2 and the rotating shaft 1 may also be fixed by interference fit.

[0036] Assembly of blade 4 and side panel 3:

[0037] like Figure 1 and Figure 6 As shown, the side plate 3 in this embodiment is fixed on the blade 4, and mounting holes 402 fixedly connected to the side plate 3 are provided at both axial ends of the blade 4. A number of through holes 301 are also correspondingly provided on the side plate 3. The second locking screw 8 passes through the through hole 301 from the outside of the side plate 3 and is fixed in the mounting hole 402 of the blade 4.

[0038] As a preferred example, Figure 6 As shown, one end of the side plate 3 has a radial groove 302 corresponding to the end of the blade 4 and a circular groove 303 corresponding to the end of the sleeve 2. A raised step 304 is formed between adjacent radial grooves 302. The raised step 304 fits the surface of the blade 4 and the sleeve 2, so that adjacent pusher cavities 5 are not connected to each other. Figure 2 As shown, the raised step 304 is raised toward the pushing cavity 5 , and the side edges of the raised step 304 are in contact with the surfaces of the blade 4 and the shaft sleeve 2 .

[0039] Embodiment 2

[0040] For different conveying precision requirements, the size of the push cavity 5 is different. To adapt to different conveying precisions, in this embodiment, a variable volume block 6 is installed on the outer circumference of the sleeve 2 between adjacent blades 4, that is, the variable volume block 6 is located in the push cavity 5. The larger the volume of the variable volume block 6, the smaller the volume of the push cavity 5. Figure 4As shown, the variable volume block 6 is an arc-shaped block that fits the outer circumference of the sleeve 2. A threaded hole 202 is provided on the surface of the sleeve 2. A connecting hole 601 corresponding to the threaded hole 202 is provided on the variable volume block 6. The first locking screw 7 passes through the connecting hole 601 and is connected to the threaded hole 202.

[0041] Embodiment 3

[0042] On the basis of the above embodiment, a chamfered surface 403 is provided at one end of the blade 4 away from the sleeve 2, so that the outer edge width of the blade 4 is smaller than the thickness of the blade 4. Figure 3 As shown, the chamfered surface 403 is the chamfer of two adjacent surfaces of the blade 4. The function of the chamfered surface 403 is to reduce the width of the outer edge of the blade 4 and reduce the wear between the outer edge of the blade 4 and the inner wall of the star feeder cavity. The chamfered surface 403 preferably connects the radial end surface of the blade 4 and the end surface facing the opposite direction of the rotation direction of the blade 4. Figure 3 The rotation direction of the middle blade 4 is counterclockwise.

[0043] The axial length of the chamfered surface 403 is smaller than the axial length of the blade 4, that is, the chamfered surface 403 does not extend to both axial ends of the blade 4, so that the radial groove 302 matched with the blade 4 is a regular rectangular groove.

[0044] Embodiment 4

[0045] A star feeder comprises the non-metallic impeller mentioned above.
