The device consists of two groups of weighing mechanisms, hang-weight mechanisms and identification mechanisms. A frame, a weighing sensor which is installed on the frame, a roller support and a roller which are arranged on the sensor, and an independent weighing mechanism which is formed by a sensor overload protector and is fixed under the sensor. The hang-weight mechanism consists of a weighing calibration weight, a weight calibration frame, a weight supporting frame, a weight moving push-pull rod and a driving device. The identification mechanism consists of two inductive sensors which are respectively installed on the weight calibration frame and the weight supporting frame. The device of the utility model has the advantages that the electronic belt scale not only can be automatically hanged weight, detected and calibrated under a dynamic state, and can be monitored and analyzed in real time, but also the weighing accuracy of the electronic belt scale can be adjusted, thereby the weighing accuracy and the production continuity of the belt scale is guaranteed.

Description

The dynamic self-correcting link code of belted electronic balance device

Technical field

The utility model relates to belted electronic balance verification link code device.It specifically is the dynamic self-correcting link code of a kind of belted electronic balance device.Can under the belted electronic balance dynamical state, carry out automatic link code, on-line proving, detection, verification.

Background technology

Existing belted electronic balance must carry out zero point to belt conveyer scale and detect and range designation before work.Scaling method generally adopts materials calibration and simulation weight scaling method.Materials calibration method precision is higher, but to consume human and material resources bigger, and expense is higher, and a lot of application scenarios are qualified to exploit not also.Simulation weight is demarcated and is generally chain code check and link code method of calibration.Above-mentioned which kind of method no matter, belted electronic balance all must be implemented to demarcate under the condition of ending normal operation, and the demarcation of belted electronic balance can not in time be carried out.

Summary of the invention

For solving the problems of the technologies described above, the utility model provides the dynamic self-correcting link code of a kind of belted electronic balance device, can carry out automatic link code, on-line proving, detection and verification to belt conveyer scale under the dynamical state of belted electronic balance.Have check code and put in place accurately, do not have characteristics such as link code drive unit additional force influence, adapt to the needs of dynamic on-line proving.

The utility model is realized with following technical scheme: the dynamic self-correcting link code of a kind of belted electronic balance device is characterized in that being included in two groups of Weighing mechanisms, link code mechanism and the identification mechanism of below, carrying roller two ends; Frame, rack-mounted LOAD CELLS, device on sensor roller rack and carrying roller and the sensor overload protective device that is fixed on below the sensor constitute independently Weighing mechanism; Link code mechanism by the verification counterweight of weighing, counterweight verification frame, counterweight bracing frame, counterweight moves pull bar and drive unit is formed, the verification counterweight of weighing places on the counterweight bracing frame, counterweight verification frame is fixed on the LOAD CELLS and forms a rigid unitary with roller rack, drives counterweight through drive unit and moves pull bar; Identification mechanism is made up of two induction pick-ups that are installed in respectively on counterweight verification frame and the counterweight bracing frame, and when the verification counterweight of weighing was in verification or Support Position, induction pick-up was exported two kinds of opposite signals respectively.

Principle of work is: weigh the verification counterweight under the driving of drive unit, form the parallel misalignment structure by counterweight verification frame, counterweight bracing frame, moved to counterweight verification frame by the counterweight bracing frame, fall automatically in the counterweight verification frame.Otherwise, when the counterweight bracing frame moves,, also fall automatically in the counterweight bracing frame by weight parallel misalignment structure by counterweight verification frame.The inverted U-shaped of counterweight bracing frame design makes counterweight that the stroke of an automatic landing be arranged after driving, and counterweight has broken away from drive unit and obtained an accurate in locating, finishes uninstall process with the quadrat method counterweight.

The beneficial effects of the utility model are: can not only carry out automatic link code, detection, verification under dynamical state to belted electronic balance, monitor in real time, analyze, can also adjust the belted electronic balance weighing precision, thereby guarantee the weighing precision and the production continuity of belt conveyer scale.
