CN-224222047-U - Novel food autofilter equipment

Abstract

Novel food autofilter equipment utilizes the line to sweep image sensor and backlight light filling lamp combination, solves the problem that prior art detection accuracy is not enough, and interference killing feature is poor, realizes high-efficient automated detection and the letter sorting of food appearance quality. When the semi-finished product is scattered on the conveyor belt uniformly, the conveyor belt drives the semi-finished product to move forward at a constant speed, when the semi-finished product runs into the field of view of the linear scanning image sensor, a clear image of the product is obtained under the light supplement of the backlight light supplement lamp, the image information is collected and then transmitted to the image processor for analysis and processing of geometric dimension and color, when the image information is inconsistent with the set value range, the information is transmitted to the central processor for calculating the product running track and the rejecting time, a command is sent to open a high-pressure gas nozzle at a designated position to spray gas, the non-conforming semi-finished product is rejected, the conforming product continues to move forward and is transferred to the next procedure.

Description

Novel food autofilter equipment Technical Field The utility model belongs to the field of novel food automatic screening equipment. Background In the food processing industry, products with irregular shapes, substandard sizes, abnormal colors or defects on surfaces of fried foods such as small crisp meat, balls and the like need to be screened in the production process. The traditional screening relies on manual visual inspection, and the operation mode has the following defects that 1, the contact opportunity of manual work and food is increased, the pollution opportunity of the food is increased, 2, the labor efficiency is low, the cost is high by 3, the influence of subjective factors is easy, and the quality standard of the product is not uniform. The existing automatic equipment mostly adopts a common camera or a photoelectric sensor, so that the detection precision is insufficient, fine defects are difficult to capture, misjudgment is caused by complex surface reflection or shadow, and the detection stability is affected. Therefore, according to the market demand, a novel food automatic screening device is developed. Disclosure of Invention In order to overcome the defects, the utility model provides novel automatic food screening equipment, which utilizes a combination of a line scanning image sensor and a backlight light supplementing lamp to solve the problems of insufficient detection precision and poor anti-interference force in the prior art and realize rapid and accurate sorting of the shape, size, color and surface defects of fried foods such as small crisp meat. The technical scheme includes that the novel automatic food screening device is characterized by structurally comprising a vibrating screen, a conveyor belt, a line scanning image sensor, a backlight light supplementing lamp, a high-pressure gas nozzle, a product removing collecting line, a qualified product collecting line, an image processor and a central controller, wherein the vibrating screen is adjacent to the conveyor belt and uniformly conveys products to the conveyor belt, the line scanning image sensor is arranged below the conveyor belt, the backlight light supplementing lamp is arranged in front of the conveyor belt and provides clear bright vision for the line scanning image sensor, the line scanning image sensor is connected with the image processor, the image processor is connected with the central controller, the central controller is connected with the high-pressure gas nozzle, the high-pressure gas nozzle is arranged above the tail end of the conveyor belt, and the product removing collecting line and the qualified product collecting line are arranged at the tail end of the conveyor belt. Advantageous effects Novel food autofilter equipment utilizes the line to sweep image sensor and backlight light filling lamp combination, solves the problem that prior art detection accuracy is not enough, and interference killing feature is poor, realizes high-efficient automated detection and the letter sorting of food appearance quality. Drawings The utility model will be further described with reference to the accompanying drawings and examples FIG. 1 is a perspective view of the present invention In the figure, a vibrating screen 2, a conveyor belt 3, a line scanning image sensor 4, a backlight light supplementing lamp 5, a high-pressure gas nozzle 6, a product collecting line removing line 7, a qualified product collecting line 8, an image processor 9 and a central controller. Detailed Description When the fried semi-finished product in the previous working procedure is conveyed onto the vibrating screen 1, under the action of mechanical vibration, the vibrating screen 1 uniformly disperses the semi-finished product onto the conveying belt 2, the conveying belt 2 drives the semi-finished product to advance in the direction of a qualified product collecting line 7 at a uniform speed, when the semi-finished product runs into the field of view of the line scanning image sensor 3, the line scanning image sensor 3 obtains a clear product image under the light supplementing of the backlight supplementing lamp 4, the image information is collected and then is conveyed to the image processor 8 for analysis processing of geometric dimension and color, when the geometric dimension or color of the semi-finished product is inconsistent with a set value range, the image processor 8 conveys the information to the central processor 9, the central processor 9 calculates the running track and rejection time of the product, when the product runs to a nozzle position, a high-pressure gas nozzle 5 which is instructed to open is arranged, under the action of gas sprayed by the high-pressure gas nozzle 5, the semi-finished product which does not meet the requirements changes the original running track and falls into the product collecting line 6 in advance, and the qualified product runs to the tail end of the conveying belt 2 to the next paraboli
