Summary of the invention
The utility model purpose is intended to overcome above-mentioned shortcoming, provides a kind of hopper can two-way feed and the accurate belted electronic balance of computation weigh.
For reaching above-mentioned purpose, the utility model adopts following solution: a kind of belted electronic balance, comprise Weighing mechanism, tachogenerator, Displaying Meter, endless-belt, drive roll, passive cylinder, hopper, hopper is arranged on the top of endless-belt, cylinder and endless-belt coupling form the circulation conveyer belt, Weighing mechanism be arranged on endless-belt below, it is characterized in that: drive roll is arranged in the middle of the following belt of belted electronic balance endless-belt, the two ends of endless-belt are provided with passive cylinder, belt just like this, go up belt during reverse rotation and be always the slack list, reduced the influence of belt tension variation, a cover Weighing mechanism respectively has been set under the endless-belt of hopper both sides measuring accuracy.
Above-mentioned belted electronic balance is characterized in that: described drive roll both sides respectively are provided with a back-up roller and increase belt contact, are connected with the endless-belt coupling; For preventing that belt skids because of tension force increases when the transported material, can add a middle transition axle on drive roll top, the supported on both sides cylinder is also become cylinder through gear, chain sprocket drive with drive roll effect.
Above-mentioned belted electronic balance, it is characterized in that: described Weighing mechanism can adopt the common scale shelf structure of simple lever, single mount roller, LOAD CELLS, also can adopt the scale shelf structure of double lever, double bracket roller, LOAD CELLS, the common scale frame that is about to two simple levers, single mount roller combines, use a LOAD CELLS, this structure has been eliminated the influence of travelling belt horizontal component to measuring accuracy, and accuracy is better than common simple lever, single mount roll structure scale frame.
Above-mentioned belted electronic balance is characterized in that: the passive cylinder in described endless-belt both sides all has independently swelling device, and belt can sideslip when guaranteeing forward and reverse rotation, install adjust very convenient.
Compared with prior art, the utlity model has following advantage:
1, is arranged on down in the middle of the belt owing to drive roll of the present utility model, belt is in the slack list state all the time on when guaranteeing the forward and reverse operation of belt, greatly reduce the influence of belt tension variation to measuring accuracy, the measuring accuracy height, and at hopper both sides configuration two cover Weighing mechanisms, can realize hopper both direction feed is carried out accurate Weighing, satisfy the commercial production needs.
2, the utlity model has characteristics such as rational in infrastructure, that measuring accuracy is high, be not subjected to the restriction of on-the-spot mounting condition, cost of manufacture is low, realize that a two-way feed of belted electronic balance weighs, overcome the shortcoming of background technology.
