Detailed implementation manners

[0042] To further understand the inventive content, features and effects of the present utility model, the following embodiments are cited and described in detail in conjunction with the accompanying drawings as follows.

[0043] The structure of the present utility model will be described in detail below with reference to the accompanying drawings.

[0044] As Figures 1 to 4 shown, a calcium sustained-release tablet granulation and forming machine provided by an embodiment of the present utility model includes:

[0045] main body 1;

[0046] former 2: The rear end face of the former 2 is fixedly connected to the front end face of the main body 1;

[0047] feeding port 3: The lower surface of the feeding port 3 is fixedly connected to the upper end face of the former 2;

[0048] cover plate 4: The lower surface of the cover plate 4 is in contact with the upper surface of the feeding port 3;

[0049] extrusion assembly 5: The extrusion assembly 5 is arranged inside the feeding port 3, and the extrusion assembly 5 includes:

[0050] material storage cylinder 501: The material storage cylinder 501 is arranged inside the feeding port 3;

[0051] Sieve plate 502: The upper surface of the sieve plate 502 is fixedly connected to the lower surface of the material storage cylinder 501;

[0052] Pressure plate 503: There are two pressure plates 503, and both of the two pressure plates 503 are arranged inside the material storage cylinder 501;

[0053] Motor 504: The outer surface of the motor 504 is fixedly connected to the upper surface of the cover plate 4.

[0054] Reference Figure 4 As shown, a connection assembly 6 is arranged on the upper surface of the pressure plate 503, and the connection assembly 6 includes:

[0055] Support frame 601: The upper surface of the support frame 601 is fixedly connected to the lower surface of the cover plate 4;

[0056] "L"-shaped connecting rod 602: There are four "L"-shaped connecting rods 602. The lower end surfaces of the four "L"-shaped connecting rods 602 are fixedly connected to the upper end surface of the pressure plate 503. The "L"-shaped connecting rod 602 penetrates through the lower surface of the support frame 601, and a stroke assembly 7 is arranged on one end surface of the "L"-shaped connecting rod 602.

[0057] Adopting the above scheme: Pour the raw materials into the material storage cylinder 501, then cover the cover plate 4, start the motor 504 through the controller. The operation of the motor 504 indirectly drives the "L"-shaped connecting rod 602 to move up and down along the inner wall of the support frame 601. When the "L"-shaped connecting rod 602 moves, it can drive the pressure plate 503 to move together. When the pressure plate 503 moves down, it squeezes the larger and harder granular raw materials, presses them to be crushed on the surface of the sieve plate 502, and passes through the sieve plate 502 and enters the inside of the former 2 for processing.

[0058] Reference Figure 4 As shown, the stroke assembly 7 includes:

[0059] Roller 701: There are two rollers 701. The front and rear ends of the two rollers 701 are rotatably connected to one end surface of the "L"-shaped connecting rod 602 through a rotating shaft;

[0060] Stroke block 702: There are two stroke blocks 702. The inner walls of the two stroke blocks 702 are in sliding connection with the outer surface of the roller 701;

[0061] Support plate 703: The lower surface of the support plate 703 is fixedly connected to the upper surface of the stroke block 702.

[0062] Adopting the above solution: In order to move the "L"-shaped connecting rod 602 up and down and move the support plate 703 left and right, the support plate 703 can drive the travel block 702 to move left and right together, so that the inner wall of the travel block 702 squeezes the roller 701, and the roller 701 is forced to move along the inner wall of the travel block 702. The roller 701 can drive the "L"-shaped connecting rod 602 to move up and down.

[0063] Reference Figure 4 As shown, four auxiliary components 8 are provided on the outer surface of the "L"-shaped connecting rod 602. The four auxiliary components 8 include:

[0064] Fixed plate 801: The inner surface of the fixed plate 801 is fixedly connected to the outer surface of the "L"-shaped connecting rod 602;

[0065] Telescopic spring 802: The telescopic spring 802 is sleeved on the outer surface of the "L"-shaped connecting rod 602. The upper end surface of the telescopic spring 802 is fixedly connected to the lower surface of the fixed plate 801, and the lower end surface of the telescopic spring 802 is fixedly connected to the upper surface of the support frame 601.

[0066] Adopting the above solution: When the "L"-shaped connecting rod 602 moves downward, it can drive the fixed plate 801 to move together. The fixed plate 801 moves downward to squeeze the telescopic spring 802, causing the telescopic spring 802 to generate elastic force. When the "L"-shaped connecting rod 602 needs to move upward, the telescopic spring 802 releases the elastic force and pushes the "L"-shaped connecting rod 602 upward.

[0067] Reference Figure 2 And Figure 4 As shown, a transmission component 9 is provided at the output end of the motor 504. The transmission component 9 includes:

[0068] Threaded rod 901: The right end surface of the threaded rod 901 is rotatably connected to the output end of the motor 504;

[0069] Transmission block 902: The inner surface of the transmission block 902 is rotationally connected to the outer surface of the threaded rod 901 through threads;

[0070] Connecting piece 903: The upper surface of the connecting piece 903 is fixedly connected to the lower surface of the transmission block 902, and the lower surface of the connecting piece 903 is fixedly connected to the upper surface of the support plate 703;

[0071] Fixing piece 904: The lower surface of the fixing piece 904 is fixedly connected to the upper surface of the cover plate 4, and the inner surface of the fixing piece 904 is rotationally connected to the outer surface of the threaded rod 901 through a bearing.

[0072] Adopting the above solution: In order to move the support plate 703 left and right, the motor 504 operates, driving the threaded rod 901 to rotate. The rotation of the threaded rod 901 can drive the transmission block 902 to move along the surface of the threaded rod 901. The transmission block 902 drives the connecting piece 903 to move left and right together, and the connecting piece 903 can drive the support plate 703 to move left and right.

[0073] Reference Figure 2 As shown, the sliding groove 10 is opened on the upper surface of the cover plate 4, and the inner wall of the sliding groove 10 is slidably connected to the outer surface of the connecting piece 903.

[0074] Adopting the above solution: The sliding groove 10 mainly serves to provide a path for the movement of the connecting piece 903.

[0075] Reference Figure 3 And Figure 4 As shown, knocking components 11 are arranged on both the left and right sides of the support plate 703. There are two knocking components 11, and the two knocking components 11 include:

[0076] Knocking rods 1101; the opposite ends of the knocking rods 1101 are fixedly connected to both the left and right sides of the support plate 703, and the outer surface of the right knocking rod 1101 is in contact with the inner surface of the storage cylinder 501;

[0077] Expansion columns 1102: The opposite ends of the expansion columns 1102 are fixedly connected to the outer surface of the storage cylinder 501, and the opposite ends of the expansion columns 1102 are fixedly connected to the inner surface of the feeding port 3;

[0078] Buffer springs 1103: The buffer springs 1103 are sleeved on the outer surface of the expansion columns 1102. The opposite ends of the buffer springs 1103 are fixedly connected to the outer surface of the storage cylinder 501, and the opposite ends of the buffer springs 1103 are fixedly connected to the inner surface of the feeding port 3.

[0079] Adopting the above solution: When the support plate 703 moves left and right, the support plate 703 can drive the knocking rods 1101 to move together until one end face of the knocking rod 1101 impacts the inner wall of the storage cylinder 501. The storage cylinder 501 is impacted to move, squeezing the expansion columns 1102 and the buffer springs 1103. When the knocking rod 1101 leaves the inner wall of the storage cylinder 501, the buffer spring 1103 releases its elastic force, pushing the storage cylinder 501 back to its initial position. This cycle is repeated to achieve a vibrating effect, enabling the raw materials on the surface of the sieve plate 502 to quickly pass through the sieve plate 502 and enter the lower part.

[0080] During use, pour the raw materials into the storage cylinder 501, then cover the cover plate 4, and start the motor 504 through the controller. The operation of the motor 504 drives the threaded rod 901 to rotate. The rotation of the threaded rod 901 can drive the transmission block 902 to move along the surface of the threaded rod 901. When the transmission block 902 moves to one end of the sliding groove 10, the motor 504 reverses, causing the transmission block 902 to move left and right. The transmission block 902 drives the connecting piece 903 to move left and right together. The connecting piece 903 can drive the support plate 703 to move left and right. The support plate 703 can drive the travel block 702 to move left and right together, causing the inner wall of the travel block 702 to squeeze the roller 701, and the roller 701 is forced to move along the inner wall of the travel block 702. The roller 701 can drive the "L"-shaped connecting rod 602 to move up and down. When the "L"-shaped connecting rod 602 moves downward, it can drive the fixing plate 801 to move together. The downward movement of the fixing plate 801 squeezes the telescopic spring 802, causing the telescopic spring 802 to generate elastic force. When the "L"-shaped connecting rod 602 needs to move upward, the telescopic spring 802 releases the elastic force and pushes the "L"-shaped connecting rod 602 upward. When the "L"-shaped connecting rod 602 moves, it can drive the pressing plate 503 to move together. When the pressing plate 503 moves downward, it squeezes the larger and harder granular raw materials, pressing them to be crushed on the surface of the sieve plate 502 and passing through the sieve plate 502 into the internal part of the former 2 for processing. While the support plate 703 moves left and right, the support plate 703 can drive the knocking rod 1101 to move together until one end face of the knocking rod 1101 impacts the inner wall of the storage cylinder 501, causing the storage cylinder 501 to be impacted and move, squeezing the telescopic column 1102 and the pressure relief spring 1103. When the knocking rod 1101 leaves the inner wall of the storage cylinder 501, the pressure relief spring 1103 releases the elastic force and pushes the storage cylinder 501 back to the initial position, repeating in a cycle to achieve the vibration effect, enabling the raw materials remaining on the surface of the sieve plate 502 to quickly pass through the sieve plate 502 into the internal part of the former 2 for processing.

[0081] In summary, for the calcium sustained-release tablet granulation former, through the main body 1, former 2, feeding port 3, cover plate 4, extrusion assembly 5, connection assembly 6, travel assembly 7, auxiliary assembly 8, transmission assembly 9, sliding groove 10 and knocking assembly 11, it solves the problems that in the raw materials stored for a long time, there may be phenomena such as caking or agglomeration of the raw materials, which will cause blockage during the granulation process. The blockage will not only affect the production efficiency but also lead to unstable particle quality.
