500 3 Main structure of the machine: 3.1 The feeding device v the unit is a feeding device, consisting mainly of hopper, feeder, adjustment screw, butterfly valve, scraper and scraper plate v The feeder is a month-shaped gate adder that can be adjusted with the turntable face clearance The amount of powder is controlled by the adjustment screw and butterfly valve 3.2 The upper pressure wheel frame device v the unit is mainly subject to the pressure plate force, which determines the incoming die depth of the upper punch The upper flush mold depth is adjustable There are mainly pressure wheel components, pressure wheel shafts, bearings and so on 3.3 The upper rail guide and the pre-pressure wheel device v the upper rail guide is equivalent to the integral cylindrical cam, which determines the trajectory of the upper punch lever's lift and movement on the circumference, and the upper rail guide seat is fixed on the top cover Mainly: rail guide, upper rail guide, stamping rail, cover plate and other parts composition The pre-pressing wheel unit is an independent adjustment mechanism The main bearing of pre-pressure plate force Pre-press edgy depth adjustable By pre-pressing and main pressure of the two tablets, the pressure out of the tablet can effectively ensure the quality of the tablet There are pre-pressing wheels, pre-pressing wheel shafts, pre-pressing wheel frames, positioning boards, etc composed of 3.4 turntable device v turntable is the main actuator of the work of the press machine, the circumference are laid with the punch There are turntables, spindles, medium-mode screws, etc The spindle has a pair of conical roller bearing supports, which are joined with the turntable and the worm box key The downpunch rod die hole is fitted with a punch bar seal Turn the handwheel so that the turntable moves clockwise 3.5 The lower rail guide device v the lower rail guide device consists of three parts: the lower rail guide, the lower pre-press wheel and the filling device The lower rail guide is a cylindrical plane cam that mainly controls the trajectory of the up and down motion of the punch ingest Consisting of the lower rush rail, the down-punch down-track, the down-punch loading and unloading rail, etc The lower up-track zui high point is the position of the piece Under the pre-pressure wheel device, mainly subject to pre-pressure and adjust the pre-pressure sheet thickness, the thickness of which is displayed by the electronic displacement gauge measurement screen He includes the lower pre-pressing wheel shaft, the lower pre-pressing wheel, the lift stick, the worm wheel worm and the coupling and the adjustment handwheel The filling unit was an adjustable structure, and he decided on the weight of the tablet Consisting of filling rails, lifters, worm wheels, worms and couplings and adjusting handwheels, the filling is measured by an electronic displacement ruler and displayed on the screen 3.6 The lower pressure wheel unit v the unit is mainly subject to pressure and adjusts the tablet thickness It is composed of lower-pressure wheel frame, pressure wheel, down-pressure wheel shaft, worm wheel box and pressure sensor The pressure wheel frame is a lever structure, and the tablet thickness is measured by the electronic displacement ruler, and its value is displayed by the screen 3.7 Rack unit v The unit is the outer cover of the machine and is a fully enclosed structure By the top cover, the middle plate, the bottom plate, the upper and lower columns, etc The upper half is closed by the window, the lower part is surrounded by stainless steel doors, the press film studio and the parts of the machine contact are stainless steel cover or surface coating isolation, open doors and windows, can be directly in contact with the machine parts, easy to operate, maintenance There is a handling box in front of the machine 3.8 Transmission v The device is mainly composed of a worm box, an electric motor, a test wheel, as well as an electronic displacement ruler, a ruler, etc., the worm box uses an advanced box-shaped shaft-mounted structure, the motor starts through the synchronous tooth belt and belt wheel, will be transferred to the worm box, through the flower key to drive the spindle and turn of the turn The motor output speed is obtained by the variable frequency variable speed, the test wheel is mounted on the snail shaft,, and the electronic displacement ruler mainly measures the filling and tablet thickness and pre-pressure tablet thickness.
