Structure and working principle of ZP35B tablet press
Mackerel is rich in iron, calcium, protein, phosphorus, sodium, potassium, niacin and vitamin B, Vitamin D group, and unsaturated fatty acids EPA and DHA. According to research, the DHA content of mackerel is second only to fat tuna in other aquatic products, ranking second. The nutritional value is extremely high. The fat is richer in unsaturated fatty acids EPA and DHA which activate the brain. It contains more fats, clear and delicious.

Second, the turntable and the upper rail guide components This mechanism is the main actuator for the tablet. It has a turntable, a main shaft, an upper and lower bearing assembly, and an upper rail guide. The main shaft has a pair of tapered roller bearing supports, which are connected with the flat key of the turntable and are splined with the worm wheel shaft. Turn the spindle to turn the turret clockwise.
The upper rail guide is a cylindrical planar cam that is the trajectory of the upper punch movement. There are upper and lower rails, upper parallel rails, and lower rails.
3. Feeding device The device is a feeding device. Mainly composed of hopper, feeder, adjusting screw, adjustable butterfly valve and powder barrier. The feeders are mounted on both sides of the turntable. The gap between the feeder and the turntable face and the height of the hopper can be adjusted. The flow rate of the powder can be controlled by the butterfly valve, and the amount of the powder can be adjusted to adjust the opening degree of the powder barrier.
Fourth, the lower rail guide and filling device lower rail guide is a circular plane cam, which controls the movement of the lower punch. It consists of the upper and lower rails.
The filling device is an adjustable structure that determines the weight of the tablet. It consists of a pair of worm helical gears and a pair of augers. The worm drive helical gear, the linkage nut moves the screw up and down, so that the filling rail installed on the screw shaft rises or falls to achieve the change of the filling amount. ,
5. Adjusting the hand wheel device The device is composed of an adjusting hand wheel, a coupling, a connecting rod and the like. The thickness of the tablet and the amount of filling can be read.
6. Machine base and transmission.
The device is composed of a bottom plate, front and rear brackets and a heat sink. The transmission part of the machine is composed of variable frequency motor, synchronous pulley, synchronous toothed belt pulley, worm gear reduction box and hand wheel. The motor is mounted on the motor board of the bottom plate. After the motor is started, the power is transmitted to the worm wheel through the timing belt and the pulley. The output speed of the motor is obtained by the inverter infinitely variable speed.
7. Peripheral cover member The outer cover is a fully enclosed structure. The upper part is closed by a window and the lower part is made of stainless steel. The contact part of the tableting studio and the machine parts are separated by a stainless steel cover. The window is supported by a gas spring. Open the door and window, it can directly contact the inside of the machine for easy operation and maintenance.
8. The electrical control box of the electrical device is a separate closed structure. The electrical control system consists mainly of electrical components, control panels and frequency converters.
