The gear transmission mechanism 25 is provided to maintain the transmission of power from the drive shaft to the driven shaft when the driven shaft moves. The gear transmission mechanism 25 is at least two gears meshed with each other; generally, 4 gears which are meshed in sequence are adopted, and a transmission gear at the head end and the tail end respectively rotate coaxially with a driving shaft and a driven shaft.
The working principle is that the small blocks of medicine are extruded into granules basically meeting the requirements between the double rollers after entering the double-roller granulating device from the jaw crushing device. Because the pair of rollers are provided with T-shaped grooves or 1-shaped grooves, and the T-shaped grooves or the 1-shaped (rectangular) grooves of the driving roller and the driven roller are in the vertical direction, when the pair of rollers roll, particles with certain sizes are naturally formed by extrusion of the T-shaped grooves of the two rollers. The automatic adjusting mechanism is positioned on the bearing seats at two ends of the driven roller, and when hard objects appear, the driven roller moves outwards under the driving of the driven bearing seats. After the hard object falls, the automatic adjusting mechanism resets under the action of the internal spring. The axial directions of the 1-shaped (rectangular) grooves of the driving roller and the driven roller are mutually vertical; one parallel to the axial direction and one orthogonal to the axial direction.
As shown in fig. 5, the separating device comprises a seat frame 30, a rocker 31, a sieve 32, a connecting rod 31, a separating device eccentric shaft 34 and a separating device belt wheel 35. The rocker 31 is a support connected to the screen and can swing left and right.
The upper ends of the rocking bars 31 are hinged with the seat frame 30, the rocking bars 31 at the two sides are connected with a sieve 32,
the left end of the connecting rod 31 is hinged with the rocker on the right side, and the other end of the connecting rod 31 is hinged with the eccentric section of the eccentric shaft. The concentric section of the eccentric shaft is concentric with the pulley 35.
The working principle is that the particles made by the roller granulating device fall into a sieve of the separating device through the receiving cylinder. The power of the motor is transmitted to the eccentric shaft 34 through the belt pulley 35, the circular motion is converted into the reciprocating motion of the sieve, and the particles in the sieve are separated under the inertia effect. The granules are the required finished product, the residual large medicine blocks of the sieve can be replaced into the medicine charging device again, and the actions are carried out again to form the finished product.
The equipment realizes automatic crushing processing firstly. Through the feeding device, the continuous quantitative feeding process of feeding is realized, namely, the continuous and stable work of the next program is ensured, and the phenomenon that the material is idled and blocked by excessive materials is avoided. Meanwhile, the medicine hopper and the feeding device are both made of copper materials, so that no spark is generated in contact with the medicine blocks, and accidents are avoided. The power of the device adopts a cylinder, so that the safety of the operation of the device is ensured. The whole equipment adopts electrostatic treatment, so that static electricity is released to the outside, and the overall safety is guaranteed.
In the jaw crusher of the next step, the jaw surfaces of the jaw plate and the jaw plate are made of copper material and fixed on steel material. The sliding table is used for driving the jaw plate to do reciprocating movement, and a cast iron slideway is also adopted. These avoid sparking and create safety issues. The device can generate increased biting force to process large medicinal blocks into small medicinal blocks.
In the double-roller granulating device, the double rollers are made of copper materials, the medicine receiving boxes are made of copper materials, and the spindle box is made of casting materials, which are considered to be safe. Meanwhile, by means of the mode of forming the i-shaped grooves in the roller, particles with fixed sizes can be formed, and medicine particles with uniform sizes can be produced. The automatic adjusting mechanism is arranged on the bearing seats at two ends, and once a large hard object exists, the driven shaft can move to one side. When the hard object falls down, the driven shaft drives the driven roller to restore the original position under the action of the spring in the automatic adjusting mechanism. Thus, the roller pair can be protected from being damaged, and meanwhile, the hard medicine blocks are not in danger under the action of high pressure.
In the separating device, the sieve is made of copper materials, which is also considered for production safety.
The whole work flow of the equipment is as follows: 1. firstly, pouring a prepared medicine block into a medicine hopper; closing a door of the explosion-proof room; a pneumatic control valve is operated outside the explosion-proof chamber to control the cylinder to move, and the material pushing rod reciprocates under the action of the cylinder to complete the pushing action of the medicine blocks; the medicine blocks continuously enter the jaw crusher along the discharge hopper. 2. The block medicine blocks are sent between the jaw plate and the movable jaw plate from the feeding device, and the movable jaw plate moves left and right rapidly under the drive of the eccentric shaft and the connecting rod to crush the medicine blocks into small medicine blocks. 3. The small blocks are extruded into granules basically meeting the requirements between the double rollers after entering the double-roller granulating device from the jaw crushing device. 4. The granules produced by the roll granulation device fall through the receiving cylinder and fall into the sieve of the separation device.
