Description

Technical Field

[0001] The utility model belongs to the technical field of weighing equipment, and in particular relates to an automatic checkweigher for multi-level weight sorting. Background Art

[0002] In many existing processing fields, such as poultry, aquatic products, candy, etc., product quality inspection includes product weight sorting, and the loading platform and sorting platform in the existing multi-stage weight sorting machine can choose chain plate conveyor or belt conveyor. However, belt conveyors are difficult to clean and cannot meet the food grade requirements of food, beverages, etc.; and although chain plate conveyors can be directly flushed or soaked in water, which is very convenient to clean, they are easy to interfere with adjacent belt conveyors, resulting in inaccurate measurement of the weight detection platform and misoperation. Therefore, the aquatic product sorting machine of the above patent is difficult to ensure weighing accuracy, or difficult to clean, and cannot meet food grade requirements.

[0003] To this end, a multi-stage weight sorting machine with announcement number "CN209061639U" includes a feeding table, an acceleration table, a weighing table, an isolation table, a sorting table, and a controller arranged in sequence from front to back. The feeding table and the sorting table use plastic chain plate conveyor belts, while the acceleration table, the weighing table and the isolation table use belt conveyor belts, and their lengths are all less than 60cm. Two first baffles are provided above the conveyor belt of the feeding table, which can be displaced in the vertical direction of the feeding table. Two second baffles are provided above the conveyor belt of the acceleration table, which can be displaced in the vertical direction of the acceleration table. A weight sensor is installed under the conveyor belt of the weighing table. A plurality of levers and unloading channels corresponding to the levers are provided on one side of the sorting table, and the levers are swung by a pneumatic mechanism. The structure is simple, which is conducive to quick and thorough cleaning, meets the requirements of food-grade processing and testing, and the weight weighing is less disturbed and has high accuracy.

[0004] However, for the above-mentioned multi-stage weight sorting machine, although the frame of the weighing platform is composed of two parts, including a separated upper part and a lower part, the conveyor belt and the upper part are installed on the weight sensor as a whole, and the weight sensor is fixedly installed on the lower part, there are still the following obvious defects during use: the above-mentioned multi-stage weighing platform is installed on the machine platform in a fixed manner, but the multi-stage weighing platforms cannot be slidably adjusted according to the actual use and installation requirements. The problem of the connection spacing between the multi-stage weighing platforms is also inconvenient to disassemble and overhaul the multi-stage weighing platforms. Utility Model Content
