Belt Scale Check Chain Code Introduction

1.What is belt scale check chain code?

Belt scale chain code is a kind of simulated load standard, can be used as electronic belt scale and weighing feeder calibration equipment.It is more convenient to calibrate and correct the measuring accuracy of the electronic belt scale if the automatic retracting and retracting and winching device is selected.

2.SMB-L type belt scale chain code product introduction

SMB-L type chain code calibration device is composed of rolling ball, chain piece, inner and outer connecting plate and hanging ring, etc.High calibration accuracy (static 0.03%, dynamic 0.1%);Compared with the physical check structure is simple, low cost, more close to reality than hanging code device;Reasonable structure, uniform composition, convenient operation;Small footprint, even the system is safe and reliable;Manpower saving, high work efficiency;Optional chain code automatic winding device, convenient and fast.The device has two types of retractable and retractable chain code: winch type or horizontal type.The winch type is the motor reducer driving the reel reel, and the electronic control device realizes the automatic retraction and retraction of the chain code.Horizontal is the form of chain code stored in the box, usually not stored in the box, use by the electronic control device operation, the belt scale chain code automatically placed on the belt above the scale body, often used in the occasion of small space above the conveyor.

3.Main features of the system

The chain code is installed above the belt, the belt balance calibration process is convenient and fast, high degree of automation, time and effort saving, accurate and reliable;The chain code is automatically operated by the electronic control system, and there are remote output contacts for remote control of the program control room;When there is a large space above the conveyor, winch type retracting device can be selected, and when the space is narrow, horizontal retracting device can be selected;Elected with winding type and device, there are two options for the user reference, a scheme is put winding charge device fixed on the conveyor frame, and need a conveyor with a device, another is to put closed device fixed on the top of the above the conveyor belt corridor, lateral movement and can be manual or electric control condition,It is used to calibrate the belt scales on two conveyors by a set of retracting and releasing devices, which can save the cost.Unit weight of chain code (kg/m) : 5, 10, 20, 30 ~ 200;Chain code accuracy: M11 level;Verifying belt scale capacity: 1 ~ 6000t/h;Applicable conveyor belt width: 500 ~ 2200mm;Working environment requirements: temperature: -35℃ ~ 65℃;Power supply: 220VAC (+10%/-15%), 50Hz (±2%) control loop part, 380VAC (+10%/-15%), 50Hz (±2%) drive part.

4.XLM series standard chain code principle and characteristics

XLM series standard chain code principle

XLM electronic belt scale international universal series standard chain code, in line with the provisions of the People's Republic of China's national metrological verification regulations JJG195-2002, is a simulated load standard,.It is more convenient to calibrate and correct the measuring accuracy of the electronic belt scale if the automatic retracting and retracting and winching device is selected.Working principle: after the electronic belt scale zero, the standard weight in the belt running, dynamic simulation of the state of the material, the weight through the scale body to the weighing sensor, at the same time, the system set the speed of the belt running at this time is constant speed, the weighing display calculation, and shows the instantaneous and cumulative amount.When the system chooses the automatic winding device, the whole chain code is put down and rewinding are completed by the electric winch, which is more convenient, simple and labor-saving.

System structure and characteristics

XLM type chain code calibration device is composed of rolling ball, chain piece, inner and outer connecting plate and hanging ring, etc. According to the design type, it can be divided into type A and type B (according to different pitch).High calibration accuracy (static 0.03%, dynamic 0.1%);Compared with the physical check structure is simple, low cost, more close to reality than hanging code device;Reasonable structure, uniform composition, convenient operation;Small footprint, safe and reliable system;Manpower saving, high work efficiency;Optional chain code automatic winding device, convenient and fast.
