Detailed description of the invention

Be described for implementing best mode of the present utility model below.Forming machine of the present utility model has: granulation portion, and it carries out compression granulation to powder; Supply unit, it is positioned at the top in this granulation portion, changes the quantity delivered of powder and supplies to granulation portion; Measurement section, it is measured operating condition.

Wherein, granulation portion possesses: pair of rolls (1) (1), and they rotate round about; Bearing block (2) (2), they support the two ends of above-mentioned roller (1) (1) and keep bearing; And press frame portion (3), their supporting shaft holders (2) (2), granulation portion carries out compression granulation to powder.Wherein " round about rotate " is that the approximating direction, surface on the top pointing to pair of rolls (1) (1) rotates.

In addition, supply unit possesses: hopper (4), and it is positioned at the top in granulation portion and supplies powder to granulation portion; And door (5), it is arranged at the inside of this hopper (4), moves up and down above the approach portion of above-mentioned roller (1) (1), and supply unit supplies the variable powder of quantity delivered to granulation portion.The supply port that the powder of hopper (4) lower end supplies to granulation portion is formed as the central supply powder from a roller (1) side direction pair of rolls (1) (1).The position of door (5) can be positioned at the center between pair of rolls (1) (1), also can be arranged in the position that relative centre departs to the side (left side of Fig. 1) supplying powder.

Further, measurement section possesses: hydraulic cylinder (8), its make movable bearing block (2) (2) with make pair of rolls (1) (1) closer to each other and be separated mode move; Force cell (9), it measures the pressure putting on roller (1) (1); And galvanometer (11), the current value of the CD-ROM drive motor (12) of its pair roller (1) (1) measures, and above-mentioned measurement section is measured operating condition.That is, the operating condition based on the rotary load pair roller of the plus-pressure between roller (1) (1) or roller (1) (1) measures.The operating condition that force cell (9) and galvanometer (11) are pair roller (1) (1) carries out the typical example of the operating condition measuring appliance measured, but other operating condition measuring appliance also can be utilized to measure operating condition.

In addition, no matter powder of the present utility model is any kind, and forming machine of the present utility model especially preferably can both be used when the character of powder and time correspondingly change.Such as reduced iron, coal, comminuted steel shot dirt processed, nickel minerals stone flour, zinc powder dirt etc., be preferably used in the powder of granularity, physical instability.In addition, forming machine of the present utility model is preferably used as the forming machine of large footpath roller.When for large footpath roller, due to the deadweight of powder, powder easily enters between roller.Therefore, it is possible to the thresholding system of utilization is to the amount of the powder supplied between roller, powder is not entered between roller.

Below, based on accompanying drawing, utility model is described.

Fig. 1 is the schematic diagram that the forming machine entirety that embodiment of the present utility model uses is shown, Fig. 2 is the enlarged section schematic diagram near the roller on the vertical plane parallel with the axle of the roller of the forming machine of Fig. 1.In FIG, roller (1) (1) rotates the roller carrying out compressing granulation to powder round about, exists in pairs.Bearing block (2) keeps pair roller (1) (1) to carry out the bearing supported.And bearing block (2) is supported on press frame (press frame) portion (3).Here press frame portion (3) external frame that is granulation portion.The downside of movable bearing block (2) is in press frame portion (3) upper slip.The horizontal direction displacement of the bearing block (2) of hydraulic cylinder (8), fixation side is limited by press frame portion (3).

On the other hand, supply unit, for arranging using hopper (4) as main parts, supplies powder to granulation portion.The inside of hopper (4) is provided with door (5), the top of roller (1) can be utilized to limit the quantity delivered of powder.That is, moved up and down by door (5) and make the gap of door (5) and roller (1) broaden or narrow, adjust the amount of the powder supplied to granulation portion from hopper (4).

In addition, the electric cylinder (6) making door (5) move up and down is remained by door lowering or hoisting gear framework (7) and flange and makes bar downward.Because the actuator moved up and down as door uses electric cylinder, therefore there is the simple advantage of structure of door.This is because pipe arrangement and hydraulic pump etc. are all indispensable when using hydraulic cylinder.In addition, the drive unit due to door is electric cylinder, therefore, it is possible to correctly adjust the height and position of door.In addition, vertically move to make the door in powder (5), also the friction between door (5) and powder is considered, powder acts on the surface pressing of door (5), for pushing the power etc. of mobile powder open, and electric cylinder (6) is made to have enough power.

In addition, forming machine can possess inverter (inverter) (10) of the speed that moves up and down of change electric cylinder (6).The reason of the speed that moves up and down of adjustment door is as described below.This is different for the power making door move up and down due to the proterties according to powder, and what the powder preferably by granulation changed door moves up and down speed.In addition, if the speed that moves up and down of door is crossed slowly, the variation of the granulation of raw material cannot be followed, if move up and down excessive velocities in addition, as swung, repeatedly may carry out knee-action.Further, if translational speed is too fast, the devices such as door are destroyed sometimes.Therefore need to make the translational speed of door be not too fast suitable speed slow only.In addition, by such as downwards time fast upwards time wait slowly and change speed according to moving direction, also can prevent breaking plant.

But measurement section possesses hydraulic cylinder (8) at the drawer at movable side of bearing block (2).And, the galvanometer (11) that the current value possessing the CD-ROM drive motor (12) of force cell (9) and pair roller (1) (1) measured the pressure putting on roller (1) (1) measures, measurement section is measured operating condition.In addition, pair of bearing (2) (2) both sides also can be made movable, and possess hydraulic cylinder (8) in each bearing block (2) (2).Hydraulic cylinder (8) can with force cell (9) interlock, the power pressed by hydraulic cylinder (8) is weakened when the pressure ratio setting putting on roller (1) (1) is large, strengthen at the pressure ratio setting hour putting on roller (1) (1) power pressed by hydraulic cylinder (8), thus suitably keep the pressure that acts between roller (1) (1).

Above-mentioned force cell (9) and galvanometer (11) are used to adjust the amount of the powder supplied to granulation portion from supply unit based on the load acting on roller (1) (1) as operating condition measuring appliance.If the pressure ratio setting putting on roller (1) (1) is high, then makes door (5) decline, make the gap turn narrow between door (5) and roller (1), thus reduce the amount of the powder to the supply of granulation portion.On the contrary, if the pressure ratio setting putting on roller (1) (1) is low, then make door (5) increase, the gap between door (5) and roller (1) is broadened, thus increase the amount of the powder to the supply of granulation portion.In addition, if the current value ratio setting of CD-ROM drive motor (12) is high, then makes door (5) decline, make the gap turn narrow between door (5) and roller (1), thus reduce the amount of the powder to the supply of granulation portion.On the contrary, if the current value ratio setting of CD-ROM drive motor (12) is low, then make door (5) increase, the gap between door (5) and roller (1) is broadened, thus increase the amount of the powder to the supply of granulation portion.Also force cell (9) or galvanometer (11) can only be possessed.On the other hand, when possessing both sides, the load of roller plus-pressure and driven roller can be made in the scope of regulation, the granulation product of more stable quality can be produced.In addition, when such as force cell (9) and galvanometer (11) illustrate contrary data, send and report to the police and arouse the attention etc. of operating personnel, the reliability of measurement section can be improved thus.

Below the action of the forming machine using these structures is described.

First, pressed the bearing block (2) of drawer at movable side by hydraulic cylinder (8), with suitable pressure, roller (1) (1) is close to.Next, by CD-ROM drive motor (12), roller (1) (1) is rotated.Thus, powder enters between roller (1) (1) of rotation from hopper (4), and powder is pressed fixing based on the pressure between roller (1) (1).Herein, the plus-pressure of force cell (9) pair roller (1) (1) is utilized to measure.On the other hand, the current value of galvanometer (11) to the CD-ROM drive motor (12) that driven roller (1) (1) rotates is utilized to measure.And, if plus-pressure or current value exceed prescribed limit, then make door (5) move up and down, adjust the quantity delivered of the powder entered between roller (1) (1).

For the adjustment of raw material (powder) quantity delivered based on door (5), the relation of opposite house height and roller plus-pressure (i.e. the measured value of force cell (9)) is investigated, and investigates the scope of the door height that can adjust raw material supplying amount.

As can be seen from test result 2, even if the rotating speed reducing helical member also may not necessarily carry out granulation with low roller plus-pressure.

As shown in the above description, in forming machine of the present utility model, measure roller plus-pressure, carry out control gate height based on roller plus-pressure, granulation can be carried out with the roller plus-pressure of constant range, granulation stay in grade thus.

In addition, the current value of the CD-ROM drive motor of driven roller is measured, utilize the current value of CD-ROM drive motor to carry out control gate height, granulation can be carried out with the roller load of constant range, granulation stay in grade thus.

Further, by utilizing electric cylinder automatic control gate height, even if thus granulation variation, also easily stably produce good granulation product.

And what adjust door by the responsiveness of VFC electric cylinder moves up and down speed, the height that can carry out the raw material being suitable for granulation change in granulation thus regulates.
