Belt Conveying feeding type electronic quantitative packing scale

Technical field

The present invention relates generally to electronic scales field, relates in particular to a kind of Belt Conveying feeding type electronic quantitative packing scale.

Background technology

For the packing of granule materials, the quality of the conformability of grain size and trickling property, all affects the speed of weighing and the accuracy rate of electronic quantitative packing scale.The feeding mechanism of general traditional electronic quantitative packing scale only to material particles relatively evenly the good material of trickling property prepare burden, for those non-particulate shapes or the very large material of particle appearance difference when the feeding at the bottom of the slow accuracy rate of speed even some material cannot carry out at all.Such as the offal dregs of beans cake that resembles refinery and generate in oil refining process, this kind of dregs of beans cake profile difference in size is very large.If using common electronic quantitative packing scale to pack at all cannot carry out.But very high again to the demand of this type of material on present market, so this kind of weighing equipment demand is higher.The present invention is carrying out in-depth study to this type of material, and the structure of traditional electronic quantitative packing scale and batching principle are upgraded, and develops Belt Conveying feeding type electronic quantitative packing scale.

Summary of the invention

The object of the invention is exactly the defect in order to make up prior art, and a kind of Belt Conveying feeding type electronic quantitative packing scale is provided.

The present invention is achieved by the following technical solutions:

A kind of Belt Conveying feeding type electronic quantitative packing scale, it is characterized in that: include frame, on the sidewall of frame, be installed with electric cabinet, the top of frame is provided with feed well, door, be positioned at a left side for the feed well of frame inside, right both sides are lifted with respectively left suspension rod, right suspension rod, left suspension rod, on right suspension rod, be installed with respectively baffle plate two, the below of two baffle plates two is provided with band conveyor, two baffle plates two are positioned at the both sides of belt conveyor, the transmission end of belt conveyor is provided with baffle plate one, the below of band conveyor is provided with motor cabinet, Frequency Converter Control box, on motor cabinet, be installed with reducing motor, frequency converter one end in Frequency Converter Control box is connected with the PLC controller in electric cabinet, one end and reducing motor control linkage, on the motor shaft of reducing motor, belt pulley is installed, between belt pulley on belt pulley and band conveyor on motor shaft, be provided with V-belt, the below that is positioned at the transmission end of band conveyor is provided with hopper, the discharging opening place that frame and below are stretched out in the bottom of hopper is provided with scale hooper, on scale hooper, be provided with and carry mechanism and sensor stand secretly, LOAD CELLS is installed on sensor stand, PLC controller in the signal output part access electric cabinet of LOAD CELLS, on the outer wall on the top of described frame, be horizontally set with cylinder by cylinder permanent seat, on the pull bar of cylinder, joint is installed, the other end of joint is rotatablely equipped with adjusting door-hinge by bearing pin, in the frame of the both sides, end of the upper end of adjusting door-hinge, be horizontally set with respectively an adjusting bolt, regulate the other end of door-hinge stretch in frame and be vertically installed with adjustment doors, PLC controller in electric cabinet and cylinder control linkage, when cylinder shrinks, drive and regulate door-hinge to rotate, the transport plane motion of adjustment doors belt conveyor downwards.

Principle of the present invention is:

In the time that equipment is started working, material trickles to band conveyor from feed well, now the PLC controller in electric cabinet sends the instruction of weighing batching to the frequency converter being arranged in Frequency Converter Control box, the frequency converter driving reducing motor of starting working, reducing motor is by two belt pulleys and V-belt, (now material bag must be inserted on scale hooper and by the bag-clamping mechanism being arranged on scale hooper and clamp) drives band conveyor convey materials to enter in the material bag being clipped on scale hooper through hopper, material bag is prepared burden, in the time that material reaches expected value, send counterweight END instruction to PLC controller and be arranged on the instrument in electric cabinet by the LOAD CELLS being arranged on scale hooper, now sending instruction by PLC controller finishes to drive to frequency converter, band conveyor stops carrying, the drive of cylinder contraction simultaneously adjustment doors moves downward to the transporting flat of band conveyor and stops material to fall, stop batching.Bag-clamping mechanism on scale hooper unclamps material bag simultaneously, and material enters subsequent processing.

Three gradating material technology (being commonly called as large throwing, middle throwing, little throwing) are applied and are easy on the good evengranular material of trickling property, directly utilize the deadweight of material just easily to realize; But the material poor to trickling property, particle is inhomogeneous is just very difficult.The frequency conversion drive Belt Conveying feeding technology that this equipment adopts utilizes frequency converter to realize three gradating materials to the mode of motor speed speed control (at a high speed, middling speed, at a slow speed) exactly.The distance in the time need to preparing burden, the extension elongation of carrying out control cylinder with the swinging distance of two adjustment bolt control and regulation door-hinges being controlled to adjust between door and band conveyor realizes the flow control to material.

Advantage of the present invention is:

The present invention has adopted frequency conversion conveying and gate control technology, adopts three gradating material technology and gate folding size to limit material flow control technique again combine according to the degree of irregularity of material particles, realized material fast, accurately weigh.
