Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, and in particular to an automatic shot press raw material conveying and filtering device. Background Technology

[0002] In the pharmaceutical industry, automatic pelleting machines are key equipment for producing various types of pellets, and the raw material conveying device, as an important component, directly affects the quality and efficiency of pelleting. With the continuous refinement of pharmaceutical processes and the increasingly stringent drug quality standards, higher requirements are placed on the accuracy, stability, and cleanliness of the raw material conveying device of automatic pelleting machines.

[0003] Currently, many automatic shot blasting machines primarily use simple gravity or screw conveying methods for their raw material conveying systems. Gravity conveying typically relies on the raw material's own weight, transporting it from a storage container to the shot blasting section via inclined pipes or troughs. Its structure is relatively simple and its cost is low. Screw conveying, on the other hand, utilizes the rotation of spiral blades to push the raw material forward along the spiral groove. This method allows for better control of the conveying speed and quantity of the raw material.

[0004] During the raw material conveying process, existing automatic pelleting machines have difficulty removing various impurities such as fibers and metal shavings from the raw materials. Once these impurities enter the subsequent pelleting process, they can easily cause mold wear, affect the pellet forming quality, and even pose a potential threat to the safety and efficacy of the drug, thereby reducing the pass rate and production efficiency of the drug. Therefore, an automatic pelleting machine raw material conveying and filtering device is proposed to solve the above problems. Utility Model Content

[0014] The quick-installation assembly includes multiple locking balls located at the other end of the input tube. A connecting tube is fixedly connected to the other end of the input tube, and a trapezoidal slot is provided inside the connecting tube.

[0015] As a further description of the above technical solution:

[0016] The outer wall of the connecting pipe is slidably connected to a second fixing pipe. The second fixing pipe has multiple holes inside. Each of the retaining balls fits into the inner wall of the hole. The diameter of the inner wall of the hole is smaller than the diameter of the outer wall of the retaining ball.

[0017] As a further description of the above technical solution:

[0018] A transmission block is slidably connected to the outer wall of the fixed tube, and a retaining ring is fixedly connected to the inner wall of the transmission block. The retaining ring is in contact with the retaining ball.

[0024] 1. In this utility model, a filter screen is used to filter impurities in the raw materials. At the same time, the rotation of the rotating blades drives the filter screen to rotate, throwing out the impurities on the surface of the filter screen, thus achieving the filtering effect of the raw materials.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 and Figure 2 An embodiment of this utility model is provided: an automatic shot press raw material conveying and filtering device, including a base plate 1, a shot press 2 fixedly connected to the top of the base plate 1, a filter assembly provided on one side of the shot press 2, an input pipe 4 fixedly connected to one side of the filter assembly, a quick-connect assembly fixedly connected to one end of the input pipe 4, a feed valve 5 provided at the bottom of the quick-connect assembly, a receiving hopper 6 fixedly connected to the bottom of the feed valve 5, and a pressure regulating valve 8 fixedly connected to the top of the receiving hopper 6;

[0034] The filter assembly includes a filter screen 15, located on one side of the shot press 2, for efficient filtration of impurities in the raw materials. A fixed pipe 3 is fixedly connected to the outer wall of the shot press 2, and a fixed block 10 is fixedly connected to the inner wall of the fixed pipe 3. A rotating shaft 11 is rotatably connected inside the fixed block 10. A rotating wheel 12 is fixedly connected to the outer wall of the rotating shaft 11, and multiple rotating blades 13 are fixedly connected to the outer wall of the rotating wheel 12. The rotating blades 13 are subjected to scouring force during the flow of raw materials, driving the rotating wheel 12 and the rotating shaft 11 to rotate. A transmission column 14 is fixedly connected to one end of the rotating shaft 11, and one end of the transmission column 14 is fixedly connected to the outer wall of the filter screen 15 to amplify the rotational force. The air is transferred to the filter screen 15, causing it to rotate synchronously to remove impurities adhering to its surface. The outer wall of the filter screen 15 is provided with a limiting component, which includes a limiting ring 16. The inner wall of the limiting ring 16 is fixedly connected to the outer wall of the filter screen 15 to limit the radial displacement of the filter screen 15. A fixing ring 17 is rotatably connected to the outer wall of the limiting ring 16 to support the limiting ring 16 and ensure its stable rotation. One end of the air pressure regulating valve 8 is fixedly connected to an output pipe 9 to regulate the air pressure to maintain a stable filtration environment. The outer wall of the fixing ring 17 is fixedly connected to the inner wall of the fixing pipe 3, and one side of the inner wall of the fixing pipe 3 is fixedly connected to one end of the input pipe 4.

[0035] Specifically, during the filtration of raw materials inside the shot press 2, the raw materials are first transported from inside the shot press 2 to the input pipe 4 via a conveying pump through a fixed pipe 3. As the raw materials flow through the fixed pipe 3, the filter screen 15 performs preliminary filtration of impurities. Simultaneously, the power generated by the flow of the raw materials washes the surface of the rotating blade 13, causing the rotating blade 13 and the rotating wheel 12 to rotate around the rotating shaft 11. This rotational force is transmitted to the surface of the filter screen 15 via the transmission column 14, causing the filter screen 15 to rotate synchronously. During the process, impurities attached to the surface of the filter screen 15 are thrown out under the action of centrifugal force, thereby effectively reducing the probability of filter screen 15 clogging. In addition, while the filter screen 15 is rotating, it will drive the limiting ring 16 to rotate on the inner wall of the fixed ring 17. The rotation of the limiting ring 16 not only ensures the stable operation of the filter screen 15, but also precisely limits its position, preventing the filter screen 15 from shifting or vibrating during high-speed rotation. Ultimately, it achieves efficient filtration of impurities in the raw materials, ensuring the purity of the raw materials inside the shot press 2 and the stability of the production process.

[0036] Reference Figure 1 and Figure 3 The quick-connect assembly includes multiple retaining balls 20 located at the other end of the input tube 4, used to achieve quick connection and separation between the input tube 4 and the fixed tube 21. A connecting tube 18 is fixedly connected to the other end of the input tube 4. A trapezoidal groove 19 is provided inside the connecting tube 18. The inclined surface design of the trapezoidal groove 19 facilitates the sliding and engagement of the retaining balls 20. The fixed tube 21 is slidably connected to the outer wall of the connecting tube 18. Multiple holes are provided inside the fixed tube 21, and each retaining ball 20 fits against the inner wall of a hole. The diameter of the inner wall of the hole is smaller than the outer diameter of the retaining ball 20, ensuring that the retaining ball 20 will not accidentally slide out of the fixed tube 21. A transmission block 23 is slidably connected to the outer wall of the fixed tube 21, and a retaining ring 22 is fixedly connected to the inner wall of the transmission block 23. 22 is fitted with the ball 20 to limit the movement range of the ball 20. The bottom of the fixed tube 21 is fixedly connected to the fixed ring 25. The bottom of the fixed ring 25 is fixedly connected to the top of the feed valve 5 to support the fixed tube 21 and ensure its stable connection with the feed valve 5. The inside of the receiving hopper 6 is fixedly connected to the transparent observation plate 7. The transparent observation plate 7 is used to observe the state of the raw materials inside the receiving hopper 6 in real time. The outer wall of the connecting tube 18 is provided with multiple arc-shaped spring plates 24. The top of the arc-shaped spring plates 24 is fixedly connected to the bottom of the transmission block 23, and the bottom of the arc-shaped spring plates 24 is fixedly connected to the top of the fixed ring 25. The arc-shaped spring plates 24 are used to provide elastic restoring force to ensure that the transmission block 23 and the retaining ring 22 can quickly reset to achieve a stable connection.

[0037] Specifically, during the replacement of the receiving hopper 6, the connection between the input pipe 4 and the receiving hopper 6 needs to be installed and disassembled. First, the transmission block 23 is pushed downwards, causing the retaining ring 22 to move out from the side of the retaining ball 20, thus providing space for the retaining ball 20 to move inside the fixed pipe 21. As the transmission block 23 moves downwards, it compresses the arc-shaped spring plate 24, allowing it to store elastic potential energy. Next, the input pipe 4 is pulled, causing the connecting pipe 18 at one end of the input pipe 4 to move out from the inner wall of the fixed pipe 21. During this process, the inclined surface of the inner wall of the trapezoidal groove 19 pushes the retaining ball 20 to slide inside the fixed pipe 21. Because the diameter of the hole inside the fixed pipe 21 is small... Due to the outer diameter of the locking ball 20, the locking ball 20 is always confined inside the fixed tube 21, preventing it from accidentally slipping out. This allows for the smooth separation of the input tube 4 from the top of the receiving hopper 6. After disassembly, the connecting tube 18 at one end of the input tube 4 is reinserted into the inner wall of the fixed tube 21. Then, the pressure on the transmission block 23 is released, and the rebound force of the arc-shaped spring plate 24 pushes the retaining ring 22 on the inner wall of the transmission block 23 to reset, causing the locking ball 20 to re-engage with the inner wall of the trapezoidal slot 19. This achieves a fixed connection between the input tube 4 and the top of the receiving hopper 6, ensuring the stability of the connection and significantly enhancing the portability of installing and disassembling the input tube 4.

[0038] Working principle: During the filtration of raw materials inside the shot press 2, the conveying pump transports the raw materials inside the shot press 2 to the input pipe 4 through the fixed pipe 3. During the flow of the raw materials inside the fixed pipe 3, the filter screen 15 filters the impurities in the raw materials. At the same time, the flow force of the raw materials washes the surface of the rotating blade 13, causing the rotating blade 13 and the rotating wheel 12 to rotate around the rotating shaft 11. This rotational force is transmitted to the surface of the filter screen 15 through the transmission column 14, causing the filter screen 15 to rotate and throwing out the impurities attached to the surface of the filter screen 15, reducing the probability of the filter screen 15 clogging. While the filter screen 15 is rotating, it will drive the limiting ring 16 to rotate inside the fixed ring 17, thereby limiting the position of the filter screen 15 and preventing the filter screen 15 from shifting. Finally, the purpose of effectively filtering the impurities in the raw materials is achieved.

[0039] During the replacement of the receiving hopper 6, which requires the installation and disassembly of the input pipe 4 and the receiving hopper 6, the transmission block 23 is pushed downwards, causing the retaining ring 22 to move out from the side of the retaining ball 20, providing space for the retaining ball 20 to move inside the fixed pipe 21. As the transmission block 23 moves, it will cause the arc-shaped spring plate 24 to compress. Next, the input pipe 4 is pulled, causing the connecting pipe 18 at one end of the input pipe 4 to move out from the inner wall of the fixed pipe 21. During this process, the inclined surface of the inner wall of the trapezoidal groove 19 pushes the retaining ball 20 to slide inside the fixed pipe 21. Since the diameter of the hole inside the fixed pipe 21 is smaller than that of the retaining ball 20, the transmission block 23 is pushed downwards, causing the retaining ring 22 to move out from the side of the retaining ball 20, providing space for the retaining ball 20 to move inside the fixed pipe 21. The diameter of the outer wall of ball 20 is adjusted to ensure that ball 20 will not accidentally slip out of the inside of fixed tube 21, thus achieving the effect of separating input tube 4 from the top of receiving hopper 6. Then, the connecting tube 18 at one end of input tube 4 is reinserted into the inner wall of fixed tube 21. Next, the pressure on transmission block 23 is released, and the rebound force of arc spring plate 24 is used to push the retaining ring 22 on the inner wall of transmission block 23 to reset, so that ball 20 is engaged with the inner wall of trapezoidal slot 19, achieving the effect of fixed connection between input tube 4 and the top of receiving hopper 6, enhancing the portability of input tube 4 installation and disassembly.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
