An airtight structure is provided. Since this sealing structure is substantially the same as that commonly used in the art, a detailed description thereof will be omitted.

The first and second rollers 20a and 20b are disposed parallel to each other at regular intervals in the main body 10 and pulverize the raw material introduced into the inlet 11 by rotation.

The first and second rollers 20a and 20b are formed in a cylindrical shape, and a plurality of pins 22 are mounted on the surface of the rollers to grind the input raw material, and the pins 22 rotate the rollers. They are spaced apart and arranged so that they can cross each other when doing so.

Further, a rotating shaft 21 is mounted on the first and second rollers 20a and 20b, and each end of the rotating shaft passes through the sealing structure and is rotatably supported by bearings in the bearing housing 41a.

It includes first and second couplings 34a and 34b connected to each of the rotational shafts so as to transmit to. That is, each power unit consists of a structure in which the rotational force of each motor is controlled by a reducer and directly transmitted to the rotational shaft 21 of the rollers connected by the coupling. Here, one end and the other end of the reducer may be positioned opposite to each other around the reducer, or may be positioned in a right angle direction.

In addition, while each power unit and the rollers connected to each power unit are moved by the distance adjusting unit 40, deflection, that is, misalignment of the drive shaft 30x and the rotation shaft 21 may occur. In the present invention, the flexible coupling (flexible coupling) to compensate for this bias. That is, the first and second couplings 34a and 34b are flexible couplings capable of correcting deflection errors, and among them, in this embodiment, a chain coupling is applied to form a pin roll mill device. . Here, the chain coupling is a type of coupling well known to those skilled in the art, and is a shaft joint using a chain. As it is connected by a chain, the shaft joint has flexibility to reduce shock and vibration, and Balance can be maintained even when the center of the two axes is slightly off.

The gap control unit 40 slides and fixes the first or second power unit together with the roller connected to the power unit to adjust the distance between the rollers. The gap control unit 40 is connected to both ends of the rotation axis of the roller and rotatably supports the lower end of the power unit that transmits rotational force to the rotation axis of the roller.

The gap adjusting unit 40 is provided with a mounting plate 41 to which a bearing housing 41a rotatably supporting the rotating shaft of each roller is mounted, and upper and lower ends of the mounting plate 41 are inserted and slideable. Upper and lower rail bars 42a and 42b on which rails are formed, support bars 43 connecting and supporting the rail bars at both ends of the upper and lower rail bars 42a and 42b, and the support bars in proportion to one-way rotation A screw thread is formed on the outer periphery so that the mounting plate 41 and the first or second plate slide with respect to (43), one end is rotatably connected to the mounting plate 41 and the other end is the support bar A rotation bar 44 passing while being screwed to (43), a support leg 45 disposed along the moving direction of the first or second plate at the lower end of the first and second plates 31a and 31b, and , One side or both sides of the support leg 45 is configured to include a moving roller 46 for slidingly supporting the bottom surface of the first or second plate.

And the spacing adjustment unit 40 has a configuration for checking the degree of movement of the mounting plate 41 by the rotating bar (44). That is, the gap adjusting unit 40 includes a roll ruler 47a and a first gap indicator bar 47b to check the degree of movement of the roller side. Here, the roll ruler 47a is mounted on the upper rail bar 42a disposed on both sides of each roller, and the first spacing indicator bar 47b has one end mounted on the mounting plate 41 and the other end It is exposed to the upper rail bar and indicates the scale of the roll ruler 47a.

In addition, the distance control unit 40 further includes a motor ruler 48a and a second distance indicator bar 48b to check the degree of movement of the power unit side. Here, the motor ruler 48a is installed on the base frame P on which the support leg 45 is installed, and the second spacing indicator bar 48b has one end mounted on the plate and the other end to the base frame P. It is extended to indicate the scale of the motor ruler 48a. Graduations in the range of 0 to 50 mm may be displayed on each ruler in millimeter units.

In addition, when the power unit and the roller connected thereto are moved by the spacing adjusting unit 40, the rotation bar 44 is compressed while the nut N fastened to the rotation bar 44 is pressed against the support bar 43 on the roller side. Rotation is prevented, and the first and second plates 31a and 31b are fixed to the support leg 45 by bolts B on the side of the power unit. To this end, on the side of the power unit, fastening holes (not shown) are formed in the support leg 45, and long holes 31h corresponding to the fastening holes are formed in the first and second plates 31a and 31b to form bolts (B ) are mutually contracted by

In addition, a center stopper 49a and a side stopper 49b are mounted on the upper and lower rail bars 42a and 42b to limit the slide movement range of the mounting plate 41 . This not only prevents excessive movement of the roller by the operator, but also serves to limit arbitrary movement of the roller and the power unit due to weakening of the fastening force.

Next, the operation of the pin roll mill device according to the present invention will be described.

When the raw material is supplied to the inlet 11 for crushing of the raw material, the raw material enters between the two rollers of the pin roll mill device according to the present invention, that is, the first and second rollers 20a and 20b, and is arranged to cross each other It is crushed by the pin 22 and discharged through the outlet 12.

At this time, in the present invention, the drive shaft 30x of the power unit is connected to the rotation shaft 21 of each roller in a direct connection method to drive the rotation shaft with a high torque driving force, so that harder raw materials can be crushed. That is, the first and second motors 33a and 33b and the first and second reducers 32a and 32b connected thereto are respectively installed on the first and second plates 31a and 31b to adjust the rotational speed of the motors. And, the driving shaft 30x whose rotational speed is adjusted in this way is connected to the rotational shaft of the rollers corresponding to each other by couplings 34a and 34b to transmit driving force.

In addition, since the distance between the first and second rollers 20a and 20b of the pin roll mill device must be adjusted according to the size of the raw material to be crushed, the first and second rollers 20a and 20b are respectively controlled by the distance adjusting unit 40. Slide and move the power unit connected to it together and fix it in the moved state.

In order to slide and move each roller and the power unit connected thereto, first, as shown in FIG. 5, loosen the bolt (B) coupled between the plate of each power unit and the support leg 45, press the support bar 43, and Loosen the nut (N) so that the rotating bar 44 can be rotated.

At this time, as shown in FIG. 6, when the rotation bar 44 is rotated, the rotation bar 44 moves the mounting plate 41 forward or backward while rotating in one direction or the other direction, and together with the rotation bar ( The plate of the power unit connected to 44 is also supported by the moving roller 46 mounted on the support leg 45 and slides.

As shown in FIG. 7, the distance between the rollers by the slide movement is visually checked through the roll ruler 47a, the first distance indicator bar 47b, the motor ruler 48a, and the second distance indicator bar 48b. You can check. Each ruler has a scale in the range of 0 to 50 mm in millimeters, so you can check and adjust the distance between each roller by checking the ruler corresponding to each roller.

And when the distance between the rollers is adjusted in this way, the distance is fixed so as not to be arbitrarily changed. That is, as shown in FIG. 8 , the rotation of the rotation bar 44 is prevented by compressing the support bar 43 by tightening the nut N fastened to the rotation bar 44 on the roller side. In addition, on the side of the power unit, the long hole 31h of each plate and the fastening hole of the support leg 45 communicating with the long hole 31h of each plate so as to fix the first and second plates 31a and 31b to the support leg 45 with a bolt B. Fasten the bolt (B) to

At this time, in order to slide and move the roller and the power unit connected thereto, a movable structure, that is, clearance between components is required. In addition, since the distance between the rollers by the slide is checked and fixed with the naked eye through each ruler and the distance indicator bar, deflection may occur between the rotation axis and the driving axis of the roller. For example, even if the spacing control unit 40 is driven so that the spacing indicator bar indicates 30 mm from the ruler, a total of three indicator bars may have an error of less than a decimal point, and this error is caused by the rotation shaft 21 and the drive shaft 30x It will cause a bias in the liver.

Since a situation in which the drive shaft and the rotation shaft may be off center may occur, a flexible coupling is used in the present invention, and in particular, a chain coupling is used in the present embodiment to compensate for such a deflection error. Therefore, the driving force by the high torque of the power unit can be transmitted to the roller by the direct coupling method between the power unit and the roller, and the misalignment between the drive shaft and the rotation shaft is corrected to enable smooth transmission of the driving force with reduced shock and vibration. do.
