Description
Technical Field
The invention relates to the technical field of color selectors, in particular to a material guiding device of a color selector.
Background
The color sorter is used as excellent material sorting equipment, is widely applied to industries such as grain processing, ore sorting and the like, and integrally comprises key components such as a conveying mechanism, an optical signal acquisition mechanism, a sorting executing mechanism and the like, and a material guiding device in the conveying mechanism of the color sorter is used for conveying materials to be sorted to the position of the optical signal acquisition mechanism, and the optical signal acquisition mechanism transmits signals to the sorting executing mechanism to sort the materials. In the prior art, in order to obtain reliable image information, it is extremely important to reasonably arrange a light source and a camera, and there are two imaging schemes of single-side camera imaging and double-side camera imaging, wherein the double-side camera imaging scheme refers to that cameras are distributed on two sides of a material throwing path obliquely upwards and obliquely downwards, and the single-side camera imaging scheme refers to that cameras are arranged on one side of the obliquely upwards or obliquely downwards of the material throwing path. Even single-sided camera imaging schemes require a background plate and a background light source on opposite sides of the camera, which are typically disposed in a mirror box, and for ease of illustration, the mirror boxes on the obliquely upper and obliquely lower sides of the material drop path are referred to as upper and lower mirror boxes. The upper mirror box and the lower mirror box are obliquely arranged up and obliquely arranged down, the material guiding direction of the material guiding groove or the plate is obliquely arranged and is in a cross form with the light path direction, the material guiding groove is of an integral structure, for materials with larger particle sizes (such as rice), the number of the materials appearing on the light path is small, and the optical signal acquisition mechanism and the sorting execution mechanism can respond in time, so that the risk effect is good. However, for some powder materials (the particle size is between 0.1 and 0.3 mm), the number of particles of the materials on the optical path is large at the same time, namely, the powder overlapping phenomenon exists in the imaging optical path direction, so that the imaging error causes serious false selection and miss selection phenomena; the distance between the upper end and the lower end of the guide chute is larger, the speed of the powder materials in the process of falling from the upper end to the lower end of the guide chute is slowly increased, the air resistance is also increased, and the particle size of the powder materials is small and the weight is light, so that the powder materials are easy to diverge when falling to the outlet of the lower end of the guide chute, imaging errors are caused, and the false selection and miss selection phenomenon are serious.

The upper guide chute section 31 is arranged in a cylinder shape, and no matter how the materials are scattered, the materials are always in the area surrounded by the cylinder, and then slowly fall from the narrow slit a.
In order to ensure that the powder and granular material smoothly falls from the second bottom plate 321 of the lower guide chute section 32, the lower end part of the first bottom plate 311 is missing to form a notch e, and the projection of the notch e on the plane where the second bottom plate 321 is located is on the second bottom plate 321. If the notch e is not provided, because the first bottom plate 311 has a certain thickness, when the powder material directly falls onto the second bottom plate 321 from the first bottom plate 311, an included angle exists between the direction of the material and the second bottom plate 321, that is, the powder material collides with the second bottom plate 321, so that the powder material diverges. Here, the notch e is formed at the lower end of the first bottom plate 311, and when the powder material falls directly from the first bottom plate 311 to the second bottom plate 321, the material is still in a cylindrical region, and then slowly falls in the narrow slit a between the second bottom plate 321 and the lower end baffle 31, so that the posture of the powder material is ensured.
For materials with different particle diameters, the slit width of the narrow slit a needs to be adaptively adjusted, an adjusting baffle 34 is arranged on the outer side plate surface of the lower end baffle 314, the adjusting baffle 34 comprises a bottom plate 341 with the plate surface perpendicular to the discharging direction and a bending plate which is formed by a flanging 344 arranged on the upper side of the bottom plate 341 and is integrally in an L shape, a strip-shaped hole 342 is formed in the bottom plate 341, the length direction of the strip-shaped hole 342 is arranged in the upper and lower direction, and a bolt 343 connected with the lower end baffle 314 penetrates through the strip-shaped hole 342 to be connected with a nut. The flange 344 is shifted by hand to enable the bottom plate 341 to slide along the strip-shaped hole 342 so as to adjust the slit width of the narrow slit a, the bolt 343 is arranged to provide a middle part for connection between the lower end baffle 314 and the adjusting baffle 34, and is matched with the strip-shaped hole 342 to guide movement of the bottom plate 341, and after adjustment is completed, the nut is used for locking the position of the bottom plate 341, so that the universality of the guide device is improved.
Further, the lower guide chute section 32 includes a second bottom plate 321 and two second side plates 322 vertically arranged at the edges of the second bottom plate 321, and in order to ensure the stability of the lower guide chute section 32, the back surfaces of the first bottom plate 311 and the second bottom plate 321 are fixedly connected with the wall of the color selector, and the groove width of the lower guide chute section 32 is greater than that of the upper guide chute section 31.
The lower end groove section of the upper guide groove section 31 is arranged in the groove cavity at the upper end of the lower guide groove section 32, the lower end of the first side plate 312 of the upper guide groove section 31 is outwardly provided with an external flanging b, and the external flanging b is clamped in a clamping groove c arranged on the second side plate 322 of the lower guide groove section 32 to form limit fit in the length direction and the width direction of the guide groove or plate 10. The relative positions of the upper guide chute section 31 and the lower guide chute section 31 are limited through the clamping fit of the external flange b and the clamping groove c, and the structure is simple and the disassembly and the assembly are convenient.
