Background
The traditional chute type color sorter utilizes gravity to enable materials to slide along a chute at a high speed, and certain materials cannot slide at a constant speed or jump up and down in the sliding process, so that the color sorting precision is not high. A fixed time delay and a stable running track are needed from the position where the material is found to the position where the removing device is located, and the material jumps up and down on the chute, so that the material cannot run on the chute at a constant speed. The speed is not uniform, and the delay time of the erasing device is not uniform, so that the early operation or the delayed operation of the erasing device is formed, and finally, the color selection precision is reduced.
Because the crawler color sorter is to rely on belt transmission system to send the material to the sorting region, in this process, the material high-speed and at the uniform velocity operation, relative static, need fine maintenance fixed and the stability of orbit of operation of delay, just so can guarantee the precision of color sorting to the at utmost.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.
The utility model provides a structure of off tracking is prevented in belt drive, as shown in fig. 1 and fig. 2, including two structural unit from belt both sides extrusion belt respectively with the fine setting belt advancing direction, single structural unit is including the assembly body that is used for extruding the belt and being used for being fixed in assembly body fixed bolster 2 in the frame, be equipped with the open slot that is used for adjusting assembly body height on fixed bolster 2, the extrusion holding surface that is used for extruding the belt side edge on the assembly body is the non-right angle with the contained angle of belt, through adjusting the high extrusion force of assembly body in order to adjust the belt of assembly body.
The assembly body includes mounting bracket 1, ceramic rod baffle 4 and ceramic rod 3, and ceramic rod 3 is installed and is supported by ceramic rod baffle 4 at mounting bracket 1 and one end, and ceramic rod 3 is towards the belt and contact extrusion belt when mounting bracket 1 installs in the frame. The ceramic rod 3 had a diameter of 10 mm and a length of 100 mm, and was a zirconia ceramic rod, which was subjected to surface polishing treatment. The mounting bracket 1 is fixed to the fixing bracket 2 by bolts, preferably M8 bolts. The angle between the extrusion supporting surface on the assembly body for extruding the side edge of the belt and the belt is 10-60 degrees, and preferably 15-40 degrees.
The mounting rack 1 and the fixed support 2 are formed by laser cutting and welding, and the ceramic rod baffle 4 is formed by laser cutting; the fixing support 2 is made of stainless steel and is formed by sheet metal machining, and is fixed on a conveyor through screws when in use, and the mounting frame 1 is made of stainless steel and is formed by sheet metal machining and is mounted on the fixing support; the ceramic rod baffle 4 is made of stainless steel and is formed by sheet metal machining;
when the belt of the crawler machine deviates, the position of the mounting rack 1 of the ceramic rod is adjusted, so that the mounting rack 1 moves up and down in the open slot of the fixed support 2, the belt is extruded to move in the opposite direction, and the belt transmission effect is achieved without deviating.
By adjusting the position of the mounting frame 1, the belt is guaranteed not to be off tracking by generating transverse extrusion force on the belt. When the belt deviates, the structural unit for regulating the deviation direction changes the position of the ceramic rod 3 by regulating the upper position and the lower position of the ceramic rod 3. Because the oblique angle is formed between the ceramic rod 3 and the belt, when the position of the ceramic rod 3 changes, the transverse extrusion force of the belt from the ceramic rod 3 changes, and finally the belt moves to the opposite direction of the belt deviation
The application can be applied to belt transmission systems with low load, including crawler color sorters.
