Abstract

The utility model relates to a cement packaging machine, belonging to the packing machinery of metering the loading of the cement. The cement packaging machine comprises a hand-operated gate valve, an ash discharging mechanism, a bagging mechanism, a controlling mechanism, a power transmitting part and an electric parts, wherein, the metering mechanism is a three-stage lever scale, wherein, and the ends of resisting force arms of the fist-stage lever and the second-stage lever are respectively provided with a rolling bear which is matched with the last stage lever. Because of the rolling bear taken as a contacted point in the metering mechanism, the action is flexible to reach the higher controlling accuracy of the bag weight. The space and the form of the second-stage lever is utilized, which is the three-stage lever principle actually with compact structure, and small force arm. The large circular pipe is adopted in the auger spindle in the ash discharging mechanism, so as to make the blade area reduced to save the wattless consumption, and meanwhile to improve the technics of the assembly of the external end axle of the auger.

Description

Cement-packing plant

The utility model relates to a kind of cement-packing plant, belongs to the metering packing machinery that cement is irritated bag.

At present, the cement-packing plant like product is more, and is various informative, but all exist the coarse problem of metering, reason is that metering mechanism adopts the second lever scale, and the arm of force is bigger, in addition, ash discharge mechanism adopts impeller, as runs into external conditions such as cement humidity or bag of cement permeability to air difference when bad, can influence the output and the control accuracy of packing, what have stirs the formula wrapping machine when design stirs, and it is excessive to stir area, pitch is long, the rotating speed height causes reactive power consumption excessive, wastes energy.

The purpose of this utility model is in order to overcome above-mentioned weak point of the prior art, and provides a kind of metering accurate, the cement-packing plant that ash discharge mechanism is reasonable in design.

The purpose of this utility model is achieved in that this machine is by hand sluice valve, ash discharge mechanism, pack device, control mechanism, Power train and electric part, metering mechanism is three grades of beam scales, and wherein the resistance arm end of one-level lever and second lever is equipped with the antifriction-bearing box that matches with its upper class lever respectively.Ash discharge of the present utility model mechanism adopts stirs pusher ash discharge.

The utility model compared with prior art, metering mechanism adopts the axis of rolling to make contact point, is active in one's movements, can reach the heavy precision of higher control bag, utilizing the locus and the form of second lever, is three grades of lever principles, so compact conformation in fact, arm of force ratio is 1: 30, the arm of force is smaller, the control accuracy height, and the mandrel that stirs in the ash discharge mechanism adopts big pipe, thereby make blade area dwindle the saving reactive power consumption, improved the manufacturability that disturbs outer end axle assembling simultaneously.

The explanation of accompanying drawing drawing:

Fig. 1 is a complete machine structure scheme drawing of the present utility model;

Fig. 2 is a metering mechanism of the present utility model scheme drawing;

Fig. 3 is an ash discharge structural scheme of mechanism of the present utility model;

Fig. 4 is a control mechanism scheme drawing of the present utility model.

Below in conjunction with drawings and Examples in detail the utility model is described in detail.

The utility model is by hand sluice valve (5), ash discharge mechanism (4), metering mechanism (1), control mechanism (3), pack frame (2), bag dish (8), ash discharge mouth (9), presses a bag device (10), constitutes near switch (12), electromagnet (11), motor (7), frame (6).Hand sluice valve (5) is positioned at the top of complete machine, by entering a UNICOM of stirring of ash bucket and ash discharge mechanism (4), the front end that stirs tube is equipped with ash discharge mouth (9) by control mechanism (3), pack frame (2) elasticity is connected on the frame (6), its top is connected with metering mechanism (1) by steelyard hook, and the bottom is fixed with bag dish (8), presses bag device (10) to be installed in ash discharge and chews on (9), frame (6) bottom is provided with motor, is connected with the outer end axle that stirs of ash discharge mechanism by transmission device.When the utility model carries out cement packing, bag of cement is inserted ash discharge mouth (9), press this moment bag device (10) simultaneously bag of cement to be compressed, open out composite plate, cement stirs at spiral under the progradation of holding together, pour into bag of cement through ash discharge mouth (9), when can weight reaches setting value, near switch (12) conducting electromagnet (11), electromagnet (11) adhesive, control mechanism is carried out closed gate, stop to irritate bag, fall bag automatically with bag of cement even fall bag mechanism automatically.

Metering mechanism of the present utility model is positioned at the top of complete machine, this mechanism is three grades of beam scales, the antifriction-bearing box (21,18) that matches with its upper class lever is equipped with respectively in the resistance arm portion of its one-level lever (17) and second lever (20), three grades of levers (15) are as the scale chi, which is provided with sliding weight (16), the position, the left and right sides of adjusting sliding weight (16) can change setting value.The other end bottom of three grades of levers (15) hangs with sliding weight of steelyard (13), sensing chip (14) is equipped with on top, this sensing chip (14) is corresponding near switch (12) with its top, and the power arm end of one-level lever (17) is connected with the pack frame (2) of placing bag of cement by steelyard hook.When bag of cement installs to setting value, the antifriction-bearing box (21) of one-level lever (17) one ends upwards promotes second lever (20), the antifriction-bearing box (18) of second lever (20) one ends around fulcrum (19) to pressing down three grades of levers (15), the sliding weight of steelyard (13) of three grades of levers (15) other end has then upwards been lifted up, sensing chip (14) is close near switch (12), this switch conduction makes electromagnet (11) adhesive control mechanism (3) close out the composite plate (see figure 4), reaches the purpose of the heavy precision of control bag.

Ash discharge mechanism of the present utility model (4) adopts spiral to stir, this stirs mandrel (23) and is cylindric, bearing seat on the inboard of its outer end axle (25) is held (24) and is fixed on frame (6) by twin roller self-regulated axle is connected, the outside is connected with bearing seat on being fixed on frame (6) by boring cylindrical bearing (28), disturb on the outer end axle (25) of mandrel (23) belt pulley (26) is housed, it is connected with motor (7) wheel by cone belt (27), the top of stirring tube (29) is provided with ash inlet, this mouth and hand sluice valve (5) UNICOM, the front end bottom of stirring tube (29) is provided with ash hole (22), and this mouth is by control mechanism (3) and ash discharge mouth (9) UNICOM.Of the present utility modelly stir mandrel (23) and make by the great circle pipe and form, thereby reduced blade area, stir the outside employing of mandrel (23) outer end axle (25) and bore the axial force backward that cylindrical bearing (28) disturbs with counteracting, the inboard twin roller self-regulated axle that adopts is held (24) so that automatic aligning, reduce the internal stress of assembling, improve the manufacturability of assembling.
