Problems solved by technology

[0005] The purpose of the present invention is to overcome the above disadvantages, thereby providing an air-film weighing device in an automatic sorting scale, which fundamentally solves the symmetrical problems of motor vibration, belt deviation, and wear and tear of parts in the prior art. Re-cause the problem of large deviation, so that the load cell has no interference in the process of feedback signal, and the feedback signal is more real; in the process of object sorting, the speed is fast and the precision is high

Abstract

The invention relates to an air-film weighing device in an automatic sorting scale, which mainly adopts a weighing sensor to be installed on a sensor fixing seat, a sensor mounting plate is installed on the weighing sensor, a bracket is installed on the sensor mounting plate, and the air pressure The suspension chamber is installed on the bracket, and a polytetrafluoroethylene plate is installed on the upper surface of the air pressure suspension chamber. A sealing rubber plate is placed between the polytetrafluoroethylene plate and the air pressure suspension chamber, and the air pipe interface is installed on the air pressure suspension chamber. The invention has a simple, compact and reasonable structure; it fundamentally solves the problems of motor vibration, belt deviation, parts wear, etc. that cause large deviations in weight in the prior art, so that the weighing sensor does not have any problems in the process of feedback signals. Interference, the feedback signal is more real; and there is no processing difficulty, reducing the cost; in the process of object sorting, the speed is fast and the precision is high.

Description

technical field [0001] The invention relates to an air-film weighing device in an automatic sorting scale, specifically a weighing device in the automatic sorting scale, which is used in conjunction with a transition conveyor and a rejecting conveyor. Background technique [0002] In the prior art, the weighing device generally adopts a conveyor structure, that is, a belt conveyor driven by a motor is mounted on a load cell. [0003] The specific structure is as follows: a fixed bracket with high rigidity is installed on the load cell, and outriggers supporting the main body of the conveyor are installed on the fixed bracket, and the main body of the conveyor is supported by the outriggers below. The main body of the conveyor is composed of conveyor belt, driving roller, driven roller, supporting plate, main frame, geared motor, geared motor bracket, transmission device (including pulley and synchronous toothed belt) and adjusting bolts. Bearings are installed at both ends ...
