Structural description of two-color powder tablet press machine1

1. The top cover of the two-color powder tablet press for the upper pressing side frame device is an overall casting, and the pressing wheel is installed in the groove, which is set on the crankshaft of the engine. There is a mechanical rod connected to the coil spring on the outer edge of the shaft. At the same time, the axial torque of the engine crankshaft acts to shrink the torsion spring, expand the distance between the upper and lower compression wheels, and reduce the working pressure, thereby maintaining the safety of the parts and the cold die, adjusting the working pressure, and turning the flower-shaped handle to change the torsion spring. The length is so that the pressure of the torsion spring is just enough. 2. The slide rail disk of the upper rail device is a disc shape, and the slide rail pieces that have been quenched and tempered are embedded around the periphery, and are tightened with screws. The concave groove at the end of the upper punch runs along the convex edge of the slide rail to make a movement Trajectory adjustment fitness movement. 3. The 35-hole roulette device The roulette is a whole casting, with 35 vertical and evenly distributed die holes around it, and 35 cold punching dies are installed in the holes, which are generally set on the fixed turntable bearing. Worm drive, the overall wheel rotates clockwise with all the dies. 4. Rotating shaft with clutch device. The rotating shaft of the two-color powder tablet press is installed horizontally in the rolling bearing fixed bracket. There is a worm rod in the middle, a test hand wheel in the front, and a conical disc clutch in the back. There is a rocker automatic switch and parking. In the car, the contact of the clutch is transmitted by the pressure of the coil spring. If the load of the device exceeds the load of the torsion spring, deviation will occur, so as not to cause serious damage to the device. 5. The feeder device is equipped with a bucket-shaped cone-bottomed feeder and a moon-shaped flow back grid-type feeder, which is used to feed the pressed material and tablet candy. Pay attention to the installation of the feeder, and its plane should be corrected until it touches the surface of the rotating disk at the end of the meeting. Generally, there is a gap of 0.03-0.1mm, and the gap can be adjusted by the supporting device. Powder quantity adjustment method, there is an extrusion tap screw on the top of the silo frame, in order to adjust the relative height of the silo and control the total flow of powder, the relative height must be based on the size of the particles and the filling amount, and the grid feeding can be observed. The accumulation of powder in the device should not flow out to meet the standard. After adjustment, the extrusion tap screw on the side should be tightened. 6. Behavior body, lower rail, diastolic pressure wheel device. Tighten it, when the punch is in operation, its tail end is embedded in the rail guide groove, and the fitness movement is adjusted along with the inclination of the groove. The use of the lower punch of the device, the diastolic pressure wheel is installed in the groove of the main body, and it is set on the crankshaft of the engine. The outer edge of the crankshaft is equipped with a bevel gear and the worm is connected with each other, and the worm is rotated according to the deceleration of the transmission gear. A small amount of rotation, when the axial force of the shaft is upward, the pressing material will rise, the pressure will increase the thickness of the sheet, and the pressure will increase the thickness of the sheet, thereby controlling the thickness, hardness and softness of the sheet. The marks on the watch plate correspond to the thickness of the sheet from 0-6, because the bevel gear has a locking function, which allows adjustment during operation, but after adjustment, the inner flower handle should be tightened. 7. Filling adjustment device The filling adjustment device is in the internal structure of the main body, and a moon-shaped filling rail can be observed at the level of the main body. It is raised or lowered by a spiral function to control the filling volume. On the disk The scale on the scale from 0-45 is equal to 0.01mm per grid of the filling volume. When the disk is rotated for adjustment, the filling volume increases when turning to the right, and decreases when turning to the right. Enterprise is mm. 8. Frame and motor device The frame of the two-color powder tablet press machine is a three-dimensional square box shape, and the motor is installed on the movable plate inside. When adjusting the speed, rotate the outer ring main shaft of the frame, and release the center of the hand wheel when adjusting. After extruding the tap nut, rotate the main shaft, turn left quickly, and turn right slowly. After adjustment, the extrude tap nut should be tightened. The base is equipped with household appliances, and the middle door is equipped with a galvanometer and a knob switch. And the green and red display lights, the green light is on when the switching power supply is connected. It indicates that the route has electricity. When the motor is started, the green light is off and the signal light is on, indicating that the motor is running normally. The ammeter is used to measure the load of the motor. 9. The powder booster device The powder booster box is a rectangle, which is installed on the left side of the machine base. There is a fan behind it, which is driven by a triangular worm gear. The bottom is a powder storage room, and the top is a powder filter room with a ring-shaped filter cloth inside. There are 5 bags. When the fan is working, the adsorption force is generated, so that the flying powder formed on the cold punching die and the powder falling from the vertical mold fall into the powder storage room through the powder increasing pipe, and the gas turns and rises according to the powder filter bag. When it is discharged, the fine powder contained in the air will remain in the powder filter bag, so after a certain period of time, the filter powder bag may be blocked and lose its effect. If the powder inside is in the form of powder, open the door to discharge it, pay attention to the isosceles triangle installation of the door and the powder pipe, the joint will leak steam, otherwise it will affect the efficiency of powder increase. 10. C-type infinitely variable speed wheel device It is installed on the motor shaft, and its internal structure has two slope flaps, which are supported by 12 coil springs on both sides to form positive pressure. The speed adjustment method is to move the motor so that the two wheels The middle distance changes, and the V-belt correspondingly expands or reduces the half-warp in the movable blade slot, and the speed changes due to the change of the half-warp, thereby realizing the infinitely variable speed regulation in a certain area.
