[0002] When using granular drug extrusion granulation production equipment to granulate drugs, first, the evenly stirred paste drug raw materials need to be squeezed into the granulation chamber. The cross-section of the granulation chamber is the shape of the drug particles. The paste drug raw materials are shaped in the granulation chamber and extruded out of the granulation chamber, and finally cut into particles by a cutting machine.

[0003] However, in the process of using traditional granulation production equipment, the drug particles exposed in the granulation chamber are cut by the friction between the cutter and the outer surface of the granulation chamber. After a long time of use, the cutter and the surface of the granulation chamber will be worn due to friction. When it continues to be used, there will be a gap between the surface of the cutter and the surface of the granulation chamber, which will cause the edges of the cut particles to be blurred and the cutting surface to be uneven.

[0004] Therefore, it is necessary to provide a new granular drug extrusion granulation production device to solve the above-mentioned technical problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0023] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic structural diagram of a preferred embodiment of the granular drug extrusion granulation production device provided by the utility model; Figure 2 for Figure 1 An enlarged schematic diagram of part A is shown; Figure 3 for Figure 1 An enlarged schematic diagram of part B is shown; Figure 4 for Figure 1 The schematic diagram of the connection structure of the output shaft, connecting sleeve, ball seat and ball and other components shown; Figure 5 for Figure 4 An enlarged schematic diagram of part C is shown.

[0024] The granular drug extrusion granulation production device comprises a granulation chamber 1 provided with an outlet, a cutting knife 2 and a motor 4; the cutting knife 2 is fixedly connected with a connecting sleeve 5, and the connecting sleeve 5 is slidably sleeved on the output shaft 401 of the motor 4; the output shaft 401 is fixedly connected with a stop block 6 protruding outward, and the connecting sleeve 5 is provided with a stop slot 7 matching the stop block 6, and the stop block 6 is slidably sleeved in the stop slot 7; the output shaft 401 is sleeved with a spring 3 and a first stop block 8, one end of the spring 3 abuts against the cutting knife 2, and the other end of the spring 3 abuts against the first stop block 8. Even if the cutting knife 2 and the outer surface of the granulation chamber 1 are worn, the extrusion of the cutting knife 2 by the spring 3 can make up for the gap caused by the wear, thereby ensuring that the cutting knife 2 and the outer surface of the granulation chamber 1 are always in contact due to the abutment.

[0025] Furthermore, a roller ball 10 is fixedly connected to the contact surface of the connecting sleeve 5 that contacts the limit block 6, and an arc-shaped sponge layer 11 is fixedly connected to the roller ball 10. A ball 12 is rollingly connected inside the roller ball 10 and the ball 12 contacts the sponge layer 11. The limit block 6 and the connecting sleeve 5 are in rolling contact through the ball 12, thereby reducing the sliding friction between the limit block 6 and the connecting sleeve 5; the sponge layer 11 has the technical effects of absorbing and slowly releasing lubricating oil. By providing the sponge layer 11, the lubrication time after each addition of lubricating oil can be effectively extended, thereby reducing the frequency of applying lubricating oil.

[0026] Furthermore, a shock-absorbing rubber pad 13 is fixedly connected to the side of the stop block 6 in contact with the ball 12, and the shock-absorbing rubber pad 13 includes a foam rubber layer 1301 located at the bottom layer and a sponge pad 1302 located at the upper layer; a shock-absorbing rubber pad 13 is fixedly connected to the side of the second stop block 9 in contact with the connecting sleeve 5, and the shock-absorbing rubber pad 13 includes a foam rubber layer 1301 located at the bottom layer and a sponge pad 1302 located at the upper layer. When the rotating cutting knife 2 contacts the granulation chamber 1, vibration will be generated due to friction, and the vibration will be transmitted to the output shaft 401 through the cutting knife 2, and then transmitted to the motor 4, causing the output shaft 401 of the motor 4 to bear torque, which will cause damage to the output shaft 401 of the motor 4 after a long time. By setting the shock-absorbing rubber pad 13, the torque borne by the output shaft 401 of the motor 4 can be reduced, thereby reducing the damage to the output shaft 401 of the motor 4.

[0027] Further, the output shaft 401 includes a threaded portion 401A, the first stopper 8 is threadedly sleeved on the output shaft 401, the first stopper 8 is threadedly connected to the output shaft 401, and the position of the first stopper 8 can be adjusted along the axial direction of the output shaft 401 to adjust the compression degree of the spring 3; since the compression degree of the spring 3 is positively correlated with the extrusion force between the cutter and the granulation chamber 1, and the extrusion force is positively correlated with the wear degree between the cutter and the granulation chamber 1, the wear degree of the cutter can be controlled within a reasonable range by adjusting the position of the first stopper 8 on the output shaft 401 to increase the service life of the cutter 2. The outer surface of the first stopper 8 is provided with friction lines 15 to facilitate the rotation of the first stopper 8.

[0028] Furthermore, it also includes four guide rods 16, each guide rod 16 is provided with a sliding sleeve 17, and the sliding sleeve 17 can slide freely along the guide rod 16; the four guide rods 16 are evenly fixedly connected to the side of the connecting sleeve 5 facing the first stopper 8, forming a cylinder whose virtual axis coincides with the axis of the connecting sleeve 5; one end of the spring 3 is fixedly connected to the connecting sleeve 5, and part of the coil of the spring 3 is always sleeved on the four guide rods 16, and the innermost side of the spring 3 is in contact with the outermost side of the guide rod 16, so as to support the spring 3, so as to keep the axis of the spring 3 coincide with the axis of the connecting sleeve 5, so that the extrusion force of the spring 3 on the connecting sleeve 5 is evenly dispersed on the connecting sleeve 5, and the extrusion effect of the spring 3 on the connecting sleeve 5 is improved; and because the extrusion effect of the spring 3 is good, the coil of the spring 3 closest to the connecting sleeve 5 is fixedly connected to the four sliding sleeves 17 respectively. The guide rod 16 is provided with a scale line 18. When the spring 3 is in a stress-free state, the connecting sleeve 5 passes over the scale line 18. By observing the position of the connecting sleeve 5 relative to the scale line 18, it can be assisted to judge whether there is a squeezing force between the spring 3 and the connecting sleeve 5.

[0029] Furthermore, an L-shaped rotating handle 19 is included, a thread groove 20 is provided on the first stopper 8, an external thread 14 matching the thread groove is provided on the other end of the rotating handle 19, and the rotating handle 19 is threadedly connected in the thread groove 20. By providing the rotating handle 19, the driving torque for rotating the first stopper 8 can be increased, thereby achieving the purpose of labor saving.

[0030] The working principle of the granular drug extrusion granulation production device provided by the utility model is as follows:

[0031] The motor 4 drives the cutting blade 2 to rotate, and cuts off the columnar drug paste exposed in the granulation chamber 1. The cutting blade 2 is squeezed by the spring 3 and can slide freely along the output shaft 401, so the cutting blade 2 and the outlet end face of the granulation chamber 1 are always against each other.

[0032] Compared with the related art, the granular drug extrusion granulation production device provided by the utility model has the following beneficial effects:

[0033] The utility model provides a granular medicine extrusion granulation production device, a spring 3 squeezes a cutting knife 2 and the cutting knife 2 can slide freely along an output shaft 401, so the cutting knife 2 and the outlet end face of a granulation chamber 1 are always in contact with each other, thereby avoiding blurring of the edges of the medicine particles and uneven cutting surfaces due to a gap between the cutting knife 2 and the granulation chamber 1; the limiting block 6 and the limiting card slot 7 are used in combination, which can avoid the cutting knife 2 from rotating around its own axis when it slides freely along the output shaft 401.
