Description

Technical Field

[0001] This utility model relates to the technical field of pharmaceutical excipient processing equipment, specifically a feeding device for preventing accumulation in pharmaceutical excipient production. Background Technology

[0002] Pharmaceutical excipients refer to the excipients and additives used in the production of drugs and the preparation of prescriptions; they are substances, other than the active ingredient, that have undergone reasonable safety assessments and are included in pharmaceutical formulations. Besides acting as excipients, carriers, and improving stability, pharmaceutical excipients also have important functions such as solubilization, co-solubilization, and sustained-release, and are important components that may affect the quality, safety, and efficacy of drugs.

[0003] The prior art provides a feeding device for pharmaceutical excipient production (publication number CN215389695U), including a main body, a feeding mechanism, and a crushing mechanism. The feeding mechanism is installed on the top of the upper end of the main body, and the crushing mechanism is connected inside the main body. The feeding mechanism further includes: a funnel; a feed inlet connected to the outside of one side of the funnel; and an end cap fixed to the outside of the upper end of the funnel. In this feeding device for pharmaceutical excipient production, the air outlet of the blower is directly opposite the feed inlet, so that the suction force generated is fully applied to the raw materials inside, ensuring a continuous feeding of raw materials. The raw materials enter the interior of the main body, and the crusher crushes the raw materials, preventing some larger solid raw materials from directly entering the processing chamber through the discharge pipe, which is more conducive to the subsequent dissolution processing. While crushing, the rotating sweeping plate collects some raw materials that fall onto the slope through the filter screen towards the discharge pipe, improving the overall feeding speed.

[0004] Based on the above patent search, in actual use, since the filter screen is fixed, after a long period of use, the pharmaceutical excipients that have not been fully pulverized are prone to clogging the filter screen, which will lead to the accumulation of pharmaceutical excipients and prevent them from passing through normally. This will affect the smooth operation of the entire feeding device, which will not only prolong the production cycle, but may also reduce the overall production efficiency due to frequent shutdowns for cleaning. Therefore, we need to propose a feeding device for pharmaceutical excipient production that prevents accumulation. Utility Model Content

[0005] The purpose of this utility model is to provide a feeding device for pharmaceutical excipient production that prevents accumulation. By setting up the anti-accumulation component, the inner material cylinder and the filter plate can be driven to reciprocate, which can effectively prevent pharmaceutical excipients from accumulating on the filter plate and ensure that the pharmaceutical excipients can pass through the filter plate smoothly for filtration, thereby improving the feeding efficiency and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

The outer side of the cam abuts against the outer side of a connecting ring. Multiple sets of sliding rods are installed on the outer side of the connecting ring. A return spring is sleeved on the outer side of each set of sliding rods. The other end of each set of sliding rods passes through the outer material cylinder and is fitted with a limit block.

[0009] Preferably, the two ends of the multiple sets of reset springs respectively abut against the limiting block and the opposite side of the outer material cylinder, and the multiple sets of slide rods are all slidably arranged inside the outer material cylinder.

[0010] Preferably, two sets of fixing rods are installed inside the outer cylinder, and two sets of connecting blocks are symmetrically installed on the outer side of the connecting ring.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention, through the setting of an anti-accumulation component, uses a first motor to drive a first rotating rod to rotate, which in turn drives a cam to rotate. The outer side of the cam abuts against the outer side of the connecting ring. As the cam rotates, combined with the elastic potential energy of the return spring, it continuously pushes the connecting ring and its connected inner cylinder to reciprocate up and down. This reciprocating motion effectively prevents pharmaceutical excipients from accumulating on the filter screen, ensuring that the pharmaceutical excipients can pass smoothly through the filter screen for filtration, thereby improving feeding efficiency. It also realizes automated control, eliminating the need for frequent manual cleaning of the filter screen, which not only reduces the labor intensity of operators but also improves the automation level of the production line, making the entire production process more efficient and stable.

[0021] 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.

[0022] Please see Figure 1-3 This utility model provides a technical solution:

[0023] A feeding device for preventing accumulation in the production of pharmaceutical excipients includes an outer material cylinder 1, an inner material cylinder 2 inside the outer material cylinder 1, a filter screen plate 3 at the bottom of the inner material cylinder 2, a crushing component 4 for crushing pharmaceutical excipients inside the inner material cylinder 2, a connecting ring 5 fixedly installed on the outer side of the inner material cylinder 2, and an anti-accumulation component 6 for preventing pharmaceutical excipients from accumulating on the filter screen plate 3 inside the outer material cylinder 1.

[0024] The anti-accumulation component 6 includes a support frame 61 fixedly installed at the top of the outer material cylinder 1. A first motor 62 is installed at the bottom of the inner side of the support frame 61. The output end of the first motor 62 is fixedly connected to a first rotating rod 63 via a coupling. The end of the first rotating rod 63 away from the first motor 62 is rotatably installed inside the support frame 61. A cam 64 is fixedly connected to the outer side of the first rotating rod 63. The outer side of the cam 64 abuts against the outer side of the connecting ring 5. Multiple sets of slide rods 65 are installed on the outer side of the connecting ring 5. A return spring 66 is sleeved on the outer side of each set of slide rods 65. The other end of each set of slide rods 65 passes through the outer material cylinder 1 and is equipped with a limit block 67.

[0025] Multiple sets of reset springs 66 are respectively abutted against the limiting block 67 and the opposite side of the outer material cylinder 1. Multiple sets of slide rods 65 are slidably arranged inside the outer material cylinder 1. Through the arrangement of springs and slide rods 65, the reset springs 66 and slide rods 65 work together to form an effective buffer reset. When the inner material cylinder 2 is subjected to external force, the reset springs 66 will be compressed. When the external force disappears, the springs will release energy to help the inner material cylinder 2 reset smoothly. This can drive the inner material cylinder 2 and the filter plate 3 to reciprocate, preventing the pharmaceutical excipients from accumulating on the filter plate 3.

[0026] The inner material cylinder 1 is equipped with two sets of fixing rods 7, and two sets of connecting blocks 8 are symmetrically installed on the outer side of the connecting ring 5. The two sets of connecting blocks 8 are slidably set on the outer side of the two sets of fixing rods 7. The fixing rods 7 and connecting blocks 8 provide support and guidance for the inner material cylinder 2, enabling it to move smoothly within the specified range and avoiding equipment failure or pharmaceutical excipient accumulation caused by shaking or deviation.

[0027] The crushing assembly 4 includes a second motor 41 fixedly installed on the top of the inner material cylinder 2. The output end of the second motor 41 is fixedly connected to a second rotating rod 42. The second rotating rod 42 is rotatably installed on the inner top of the inner material cylinder 2. Multiple sets of crushing blades 43 are installed on the outer side of the second rotating rod 42. Through the setting of the crushing assembly 4, the second motor 41 drives the second rotating rod 42 to rotate, thereby driving the multiple sets of crushing blades 43 to crush the pharmaceutical excipients. This design ensures that the pharmaceutical excipients can be fully crushed before entering the filter plate 3, which helps to prevent the filter plate 3 from clogging and improves the feeding efficiency.

[0028] Two sets of scrapers 9 are installed at the bottom of the second rotating rod 42. The bottom of both sets of scrapers 9 are in contact with the top of the filter screen plate 3. Through the setting of the scrapers 9, the residue on the filter screen plate 3 can be continuously cleaned to ensure that the filter screen plate 3 is unobstructed and improve the filtration efficiency.

[0029] The top of the outer material cylinder 1 is connected to the feed pipe 10, the outside of the feed pipe 10 is connected to the suction pipe 11, the bottom end of the feed pipe 10 is connected to the hose 12, the bottom end of the hose 12 is connected to the top of the inner material cylinder 2, and the outside of the feed pipe 10 is connected to the blower 13. Through the arrangement of the feed pipe 10, suction pipe 11, hose 12 and blower 13, the automatic feeding and continuous conveying of pharmaceutical excipients is realized. The blower 13 sucks the pharmaceutical excipients into the feed pipe 10 through the suction pipe 11, and then sends them into the inner material cylinder 2 through the hose 12. This automated feeding method not only improves the feeding efficiency, but also reduces the tediousness and error of manual operation. At the same time, a filter is set in front of the blower 13 to prevent the pharmaceutical excipients from entering the blower 13, which plays a protective role.

[0030] The bottom of the outer material cylinder 1 is conical, and the bottom end of the outer material cylinder 1 is connected to the discharge pipe 14. The conical outer material cylinder 1 makes it easier for pharmaceutical excipients to collect at the discharge pipe 14 after filtration, which facilitates rapid subsequent feeding.

[0031] Working principle: When this utility model is in use, the suction pipe 11 connected to the outside of the feed pipe 10, under the action of the blower 13, sucks in the pharmaceutical excipients and sends them into the inner material cylinder 2 through the hose 12. At this time, the second motor 41 is started, and the second motor 41 drives the second rotating rod 42 to rotate. The second rotating rod 42 drives multiple sets of crushing blades 43 to rotate. During the rotation, the pharmaceutical excipients are crushed into smaller particles. Then, the first motor 62 is started, and the first motor 62 drives the first rotating rod 63 to rotate, which in turn drives the cam 64 to rotate. The outer side of the cam 64 abuts against the outer side of the connecting ring 5. As the cam 64 rotates, it is coordinated with the return spring. The elastic potential energy of 66 will continuously drive the connecting ring 5 and its connected inner material cylinder 2 to move up and down reciprocally. This reciprocating motion can effectively prevent the pharmaceutical excipients from accumulating on the filter screen plate 3, ensuring that the pharmaceutical excipients can pass smoothly through the filter screen plate 3 for filtration, thereby improving the feeding efficiency. At the same time, during the rotation of the second rotating rod 42, the scraper 9 will continuously clean the residue on the filter screen plate 3, ensuring that the filter screen plate 3 is unobstructed. After filtration, the pharmaceutical excipients fall into the bottom of the outer material cylinder 1. Since the bottom of the outer material cylinder 1 is conical, the pharmaceutical excipients can more easily collect at the discharge pipe 14, thereby completing the rapid feeding of pharmaceutical excipients.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
