High-speed sorting roller structure

Abstract

The invention discloses a high-speed sorting roller structure. The high-speed sorting roller structure comprises a center shaft, a chain and a roller, wherein the chain is fixedly connected to the center shaft, the roller is rotationally arranged at the two ends of the center shaft in a sleeved mode, a sleeve is fixedly connected to one side, close to the chain, of the roller, the sleeve is rotationally connected with the center shaft, a gear is fixedly connected to the outer side wall of one end, far away from the roller, of the sleeve, the gear is movably connected with a rack, and the rackis fixedly arranged below the gear. According to the high-speed sorting roller structure, through the sleeve arranged at the tail end of the roller and the gear fixedly connected with the sleeve, thechain can drive the roller to perform linear motion, and meanwhile, the gear can be meshed with the rack which is fixedly arranged below the gear so as to generate friction to drive the roller to rotate.

Description

technical field [0001] The invention relates to the technical field of rollers for jujube sorting, in particular to a high-speed sorting roller structure. Background technique [0002] At present, in the domestic red jujube grading system, in order to transport one fruit at a time, the inclined sliding type and the double-roller type are mostly used. In the actual use of the double-roller method, fruit crowding and overlapping are prone to occur, which affects the accuracy of machine vision recognition. It also reduces the classification efficiency. [0003] In the prior art, the application number is CN103240228A, which is a non-destructive automatic grading machine for jujube based on machine vision technology, which adopts a chain to be installed on the outside of the roller. However, the above-mentioned device still has the following defects in use: 1. Make the above-mentioned device 2. Since the rotation of the drum is caused by the relative movement between the fricti...

[0003] In the prior art, the application number is CN103240228A, which is a non-destructive automatic grading machine for jujube based on machine vision technology, which adopts a chain to be installed on the outside of the roller. However, the above-mentioned device still has the following defects in use: 1. Make the above-mentioned device 2. Since the rotation of the drum is caused by the relative movement between the friction section of the drum and the stationary brush, slipping often occurs in the actual production process, making the camera unable to Collect the characteristics of the entire outer surface of jujubes, resulting in mispicking and omissions; 3. In order to increase the output, it is necessary to increase the moving speed of the roller, but due to the small diameter of the friction section of the roller, the jujube rotates too fast and jumps when sorting Phenomenon, which is not conducive to the recognition of surface morphological features by the camera
