Said tare weight detects weighing platform top one side and is provided with the forward roller, and opposite side is provided with and is folded to roller, said forward roller be folded to roller and be connected belt conveyor, belt conveyor is at the forward roller and be folded between the roller and be the serpentine structure of unrolling.
Compared with prior art the present invention has following characteristics.
The belt mounting means that adopts serpentine to unroll; Below feed zone, hew out the space that online peeling weighing platform is installed; Realize online peeling function; And keep the invariant position of the charging of conventional belt scale afterbody, head discharging, and have accurate measurement, stable characteristics, be applicable to most belt conveyer scale application scenario.

This device comprises feed zone 1, driven cylinder 2, drive roll 7, material metage weighting platform 6, belt conveyor 3, discharge zone 8, drive motor 9 and frame; Drive motor 9 drives with drive roll 7 and is connected; Drive roll 7 is connected with driven cylinder 2 through belt conveyor 3, and material metage weighing platform 6 feed ends are provided with tare weight and detect weighing platform 4, like Fig. 1, shown in 2; Said feed zone 1 below is provided with and isolates belt feeder 16; Isolate belt feeder 16 and comprise forward roller 10 and be folded to roller 11, said forward roller 10 be folded to roller 11 and be connected the driven cylinder 2 of said forward roller 10 connections through belt.
As shown in Figure 3; Said tare weight detects weighing platform 4 tops one side and is provided with forward roller 10; Opposite side is provided with and is folded to roller 11, said forward roller 10 be folded to roller 11 and be connected belt conveyor 3, belt conveyor 3 is at forward roller 10 and be folded between the roller 11 and be the serpentine structure of unrolling.
Described forward roller 10 be folded to roller 11 and be provided with electrostatic prevention, anti-stick glutinous coating.
Be provided with belt cleaning plant 12 with a side that is folded to the belt conveyor 3 that roller 11 is in transmission connection.
The opposite side of belt conveyor 3 is provided with pendulum stretching pulley 15, and mechanical deflection correcting device 5 increases cornerite roller 14 and is in transmission connection with bristle brush wheel 13 grades.
Described tare weight detects weighing platform 4 and is communicated with programmable logic controller (PLC) PLC respectively with material metage weighing platform 6.
Embodiment one; Shown in accompanying drawing 2; The present invention provides a kind of belted electronic balance of online peeling function, comprises that belt conveyer scale feed zone 1, driven cylinder 2, drive roll 7, tare weight detect weighing platform 4, material metage weighing platform 6 and discharge zone 8, and described tare weight detects weighing platform 4 and is in the same plane with material metage weighing platform 6; Described drive roll 7 is driven through chain wheel pair by drive motor 9, drives belt conveyor 3 motions.Below feed zone 1, be provided with one and isolate belt feeder 16, isolate belt feeder 16 and comprise forward roller 10 and be folded to roller 11, said forward roller 10 be folded to roller 11 and be connected the driven cylinder 2 of said forward roller 10 connections through belt.
Hew out the installing space of online peeling weighing platform, see accompanying drawing 2.Since online peeling weighing platform can be installed on the belt conveyer scale feed zone under, thereby keep afterbody charging, the head discharge method of conventional belt scale constant.Owing to have online tare weight measuring ability, can guarantee the characteristics that the accuracy of measuring is steady in a long-term.
