Efficient recycling of waste classification is becoming more and more important. Domestic waste mainly consists of metals, paper products, glass, natural organic materials, discarded plastic and resin products, rubber, chemical fiber products, difficult-to-regenerate combustibles, and electronic waste, most of which can be recycled.

[0003] The dry cleaning friction machine is used to remove dust from light materials such as discarded plastics, resins and chemical fibers after the initial screening of domestic waste, so as to facilitate further screening of subsequent equipment. During the operation of the machine, light materials must be able to pass quickly without accumulation, and dust must be removed and crushed to prepare for subsequent screening, which plays a key role. However, the prior art does not propose a spindle structure that can well crush materials and screen them. Summary of the invention

When the driving shaft and the driven shaft rotate, the beating rod and the blade rotate accordingly. The beating rod can quickly comb the material to prevent entanglement and facilitate the separation of the material and dust. The blade can cut and crush the material. The arrangement of the beating rod and the blade makes the dust separation and cutting effect of the dry cleaning friction machine better.

[0005] In order to achieve the above-mentioned object, the present invention provides a main shaft structure suitable for a dry cleaning friction machine, comprising a driving shaft and a driven shaft, comprising a round steel cylinder and a polygonal weldment, wherein the driving shaft and the driven shaft are respectively fixed on both sides of the round steel cylinder;

[0007] Furthermore, it also includes a blade base, the blade is fixed on the blade base, the bottom of the blade base is a bottom plate, and both ends of the bottom plate are provided with oval holes.

[0008] Furthermore, the polygonal weldment is a regular polygon, and the center angles of the two ends of the waisted circular hole are 10° to 30°.

[0009] Furthermore, the blade base is divided into a plurality of sections along the axis direction, and the blade base of each section has the same angle with the center line of the polygonal weldment.

[0010] Furthermore, the angle segments between the blade base and the center line of the polygonal weldment decrease successively along the axis.

[0011] Furthermore, each face of the polygonal weldment is tangent to the circumference of the circular steel cylinder.

Figure 2 It is a cross-sectional view of a main shaft structure suitable for a dry cleaning friction machine in an embodiment of the present invention. Figure 3 2 is a cross-sectional view schematic diagram of a main shaft structure suitable for a dry cleaning friction machine in an embodiment of the present invention. Figure 1 , Figure 2 and Figure 3 As shown, the main shaft structure suitable for the dry cleaning friction machine includes a blade base 1, a blade 2, a beating rod 3, a driving shaft 4, a driven shaft 5, a round steel cylinder 9 and a polygonal weldment 10; the round steel cylinder 9 is a hollow cylindrical structure, the polygonal weldment 10 is sleeved on the outer circumference of the round steel cylinder 9, and each surface of the polygonal weldment 10 is in contact with (tangent to) the circumference of the round steel cylinder 9, and the round steel cylinder 9 is used to provide support for the polygonal weldment 10. Preferably, the contact point between the polygonal weldment 10 and the round steel cylinder 9 is welded, and the connection between the two is more stable, thereby ensuring the strength and stability of the main shaft structure.

[0026] The polygonal weldment 10 is preferably a regular polygon, more preferably a regular hexagon or a regular octagon. The setting of the regular polygon makes the main shaft structure more uniform and the rotation smoother. It is also conducive to the uniform arrangement of the blade 2 and the beating stick 3, thereby improving the dry cleaning effect.

[0027] The polygonal weldment 10 is composed of multiple faces. Preferably, the polygonal weldment 10 is formed by welding multiple flat plates of the same size. Blade bases 1 and beating rods 3 are respectively provided on the multiple faces of the polygonal weldment 10, and only the blade base 1 or only the beating rod 3 is provided on one face, and the blade base 1 and the beating rod 3 are respectively provided on two adjacent faces, that is, the blade base 1 and the beating rod 3 are alternately provided on the polygonal weldment 10.

[0028] Among them, a plurality of blade bases 1 are arranged in parallel along the axis of the polygonal weldment 10, such as Figure 2 , Figure 3 and Figure 4 As shown, the blade base 1 includes a bottom plate 101 and a fixing plate 102, the bottom plate 101 and the fixing plate 102 are vertically arranged, and first fixing holes 103 are provided at both ends of the bottom plate 101, and the blade base 101 is fixed to the polygonal weldment 10 through the first fixing holes 103; preferably, as Figure 1 As shown, the blade base 1 is tilted, that is, the blade base is not parallel to the cross section of the main shaft, but is set at a certain angle to the cross section of the main shaft, so as to better comb and spread the materials and prevent the materials from being entangled. The implementation method is that the first fixing hole 103 is a waisted hole, and the center angle of the two ends is 10° to 30°. Preferably, the center angle of the two ends of the waisted hole is 20°, and the angle between the blade base 1 and the center axis of the polygonal weldment 10 is adjusted through the waisted hole. Preferably, the initial setting of the blade base 1 is 75°. By adjusting the position of the waisted hole, the angle between the blade base 1 and the center line of the polygonal weldment 10 can be adjusted within a larger range.

[0029] The fixing plate 102 is provided with a second fixing hole 104 , and the blade 2 is fixed to the fixing plate 102 through the second fixing hole 104 , so that a plurality of blades 2 are arranged in sequence along the axial direction of the main shaft.

Preferably, the beating rods 3 on each surface are arranged in a straight line to facilitate combing the material.

[0032] Preferably, along the axial direction, the beating rod 3 is located between the two blades to better comb and disperse the materials.

[0033] The beating rod 3 is used to comb the material to prevent the material from being entangled, and the blade 2 is used to cut the material. The two are arranged at an interval, and the dust and the material are separated and the material is crushed at the same time, so that the material can pass quickly without accumulation, and the dust on the material is quickly removed. The crushing of the material prepares for subsequent screening.

[0034] A driving shaft 4 is provided on one side of the round steel cylinder 9, and a driven shaft 5 is provided on the other side. The third circular plate 8, the second circular plate 6 and the first circular plate 7 are provided at both ends of the round steel cylinder 9 from the outside to the inside, and the first circular plate 7, the second circular plate 6 and the third circular plate 8 are arranged in parallel and are perpendicular to the axis of the main shaft; the centers of the first circular plate 7, the second circular plate 6 and the third circular plate 8 are provided with circular holes, and the driving shaft 4 and the driven shaft 5 pass through the third circular plate 8, the second circular plate 6 and the first circular plate 7 in turn, and are fixed on the first circular plate 7, the second circular plate 6 and the third circular plate 8, and then are respectively fixed at the two ends of the round steel cylinder 9, and the round steel cylinder 9 and the polygonal weldment 10 are driven to rotate by the rotation of the driving shaft 4 and the driven shaft 5.

[0035] Preferably, the thicknesses of the third circular plate 8, the second circular plate 6 and the first circular plate 7 decrease successively. The decreasing thickness setting ensures a firm connection between the driving shaft 4 and the driven shaft 5 and the round steel cylinder 9, while also reducing the weight of the main shaft and lowering energy consumption.
