Abstract

The utility model relates to a double belt electronic speed-adjusting weigher. An upper and a lower two layers of belts are dragged by a speed-adjusting motor to synchronously operate. Because the whole lower layer of belt machine and materials are introduced together into a weighing system by the utility model, the metering precision of the belt weigher is greatly enhanced. The double-belt electronic speed-adjusting weigher has compact structure of equipment and convenient use, and is capable of being widely used for carrying out continuously transportation, feed control and dynamic weighing and measurement for block and granular materials in the industries of cement, metallurgy, chemical industry, foodstuffs, etc.

Description

Two belt electronic speed regulation scales

A kind of pair of belt electronic speed regulation scale, be fit to various, granular material carry continuously, feed control and dynamic weighting, industries such as cement, metallurgy, chemical industry, grain be can be widely used in, continuous data and control device accurately reliably provided commercial production and management.

The scale frame of belted electronic balance adopts single mount roller cross reed supporting structure mostly in the prior art, the scale frame of this structure changed by belt tension and the influence of motion state variation greatly, when having bondd material or dust on the weighing carrying roller, belt be in operation sideslip, phenomenon such as beat can take place, when the tension force of belt is subjected to the influence of environment temperature, humidity and changes, can cause instrument constantly to change zero point, these factors all will have a strong impact on the degree of accuracy of weighing, the scale body of belt conveyer scale is long more, and these phenomenons are just difficult more to be overcome.

The purpose of this utility model is to overcome deficiency of the prior art, improves the measuring accuracy of belt conveyer scale.

For achieving the above object, the utility model has adopted the unique texture of the double belt convey materials that is dragged by a buncher, the upper strata belt is by the direct material drag of hopper, drop into lower floor's belt weighing metering, the feeding end of lower floor's belt feeder frame is bearing on the bearing of dress automatic aligning rolling bearing in a pair, can be around bearing rotation up and down, its discharge end then is suspended on the fixed pivot by pulling force sensor with wire rope or loop chain.

Elaborate below in conjunction with accompanying drawing:

Fig. 1. two belt electronic speed regulation scale structural representations,

Wherein: the last drive roll of 1-; 2-disk-type friction clutch handwheel; 3-bunker gate handwheel; 4-upper strata belt; The 5-tightener sprocket; The last driven cylinder of 6-; The last belt tensioning device of 7-; 8-lower floor belt; The 9-pulling force sensor; Driven cylinder under the 10-; Belt tensioning device under the 11-; Drive roll under the 12-; The 13-minor sprocket; The 14-speed reduction unit; The 15-buncher; 16-rubberite pad; The 17-rolling bearing pedestal; The 18-hopper; The 19-frame;

Fig. 2. the A of Fig. 1 is to view

Wherein: drive roll under the 12-; The 17-rolling bearing pedestal; The 19-frame; The 20-hinge wheel; The 21-rolling bearing pedestal;

As shown in the figure, following drive roll (12) and the shaft support that is connected with it are being installed on the rolling bearing pedestal of base (17), and as the frame (19) of scale frame another rolling bearing pedestal (21) kink by being fastened on the end in rotating shaft, therefore when hinge wheel (20) the following rotating while of drive roll of drive, frame (19) can reach near rolling bearing pedestal (17) rotation horizontal level around the shaft.The other end of frame (19) is suspended on the fixed pivot by pulling force sensor (9) with wire rope or loop chain, has saved the loaded down with trivial details structure of general cantilevered scale frame.In addition, the utility model only drags upper and lower two-layer belt synchronous operation by a buncher (15), and upper strata belt (4) can be under the constant situation of lower floor's belt (8) running status, control by disk-type friction clutch handwheel (2) and to end at any time or resume operation, be convenient to carry out " school zero " and " demarcation ".

Because the utility model is included whole lower floor belt feeder in Weighing system with material, can not be subjected to the influence of factors such as belt tension variation or became uneven, so improved the measuring accuracy of this belt conveyer scale largely, and its compact equipment, easy to use, can obviously improve productivity effect.

Claims (1)

1. two belt electronic speed regulation scale, by buncher, hopper, belt tensioning device, compositions such as pulling force sensor, it is characterized in that: following drive roll (12) and the shaft support that is connected with it are being installed on the rolling bearing pedestal of base (17), another rolling bearing pedestal (21) kink of frame (19) by being fastened on the end is on bearing, the other end of frame (19) is suspended on the fixed pivot by pulling force sensor (9) with wire rope or loop chain, on, following two-layer belt (4), (8) drag synchronous operation by a buncher (15), the termination or the recovery of upper strata belt (4) operation are controlled by disk-type friction clutch handwheel (2).
