Description

Technical Field

[0001] The invention belongs to the technical field of pharmaceutical excipient production, in particular to a packaging device for pharmaceutical excipient production. Background Art

[0002] Pharmaceutical excipients are usually excipients and additives used in drug production and prescription preparation. It has multiple key functions. In addition to shaping drugs, acting as a carrier and enhancing stability, it also performs outstandingly in solubilization, dissolution aid, sustained and controlled release, etc. Usually, most pharmaceutical excipients are in powder or granular form. After production, in order to ensure stability during subsequent transportation, operators usually package and store these pharmaceutical excipients in barrels. When the existing equipment barrels such pharmaceutical excipients, the storage barrel is intermittently transported by a conveyor belt. A set of feeding pipes is set above the conveyor belt. When the storage barrel is under the feeding pipe, the feeding pipe is opened so that the pharmaceutical excipient can fall into the storage barrel. However, this method will cause the powdered pharmaceutical excipient to be lifted up in the process of falling into the storage barrel, resulting in part of the pharmaceutical powder escaping from the storage tank and dispersing in the air, resulting in waste. In order to solve this problem in the prior art, a set of baffles is usually set outside the feeding pipe. When the outlet of the feeding pipe extends into the storage tank, the baffle will seal the pipe mouth of the storage tank to prevent the drug dust from diffusing to the outside. However, this method will still cause the drug dust to be dispersed in the tank body. When the feeding pipe is reset, the drug dust may still be scattered outside the tank body. Therefore, in order to solve the above problems, a packaging device for the production of pharmaceutical excipients is proposed. Summary of the invention

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 8 As shown, the present invention provides a packaging device for producing pharmaceutical excipients, comprising a conveying mechanism 1 and a storage barrel 6, and further comprising: a feeding mechanism 2, which is arranged directly above the conveying mechanism 1; a lifting mechanism 3, which is arranged on the conveying mechanism 1 and is used to drive the feeding mechanism 2 to move in a vertical direction; a sensor assembly 4, which is installed on the feeding mechanism 2;

[0033] The feeding mechanism 2 includes a cylinder 21 arranged on the lifting mechanism 3, a feeding port 22 is provided at the top of the cylinder 21, a support assembly 23 is movably sleeved at the bottom of the cylinder 21, a spring 24 is sleeved at the middle of the cylinder 21, the top of the spring 24 is fixedly connected to the cylinder 21, the bottom of the spring 24 is in contact with the top of the support assembly 23, the diameter of the support assembly 23 is larger than the diameter of the storage barrel 6, a discharge port 211 is provided in a circumferential array at the bottom of the cylinder 21, a conveying roller 26 is movably connected inside the cylinder 21, the top of the conveying roller 26 extends to the top of the cylinder 21, and a motor 25 for driving the conveying roller 26 to rotate is fixedly connected to the top of the cylinder 21;

[0034] The sensor assembly 4 includes a pressure sensor 1 41 fixedly mounted on the bottom of the cylinder 21, a pressure sensor 2 42 located directly below the spring 24 is fixedly mounted on the support assembly 23, and the bottom of the spring 24 contacts the support assembly 23 through the pressure sensor 2 42, and a control assembly 43 is also fixedly mounted in the middle of the conveying mechanism 1;

[0035] The lifting mechanism 3 includes a mounting frame 31 which is symmetrical and fixed to both sides of the conveying mechanism 1. A hydraulic rod 32 and a limit rod 33 are fixed to the middle and both sides of the mounting frame 31 respectively. A connecting frame 34 is fixed to the top of the hydraulic rod 32. Both ends of the connecting frame 34 are movably sleeved on the tops of the two limit rods 33 respectively. A clamping hoop 35 is clamped in the middle of the outer periphery of the cylinder 21. Both ends of the clamping hoop 35 are fixedly connected to the connecting frames 34 on both sides respectively.

[0036] A reduction gear set 251 is fixedly mounted on the top of the cylinder 21 , and the motor 25 is drivingly connected to the conveying roller 26 via the reduction gear set 251 .

[0037] By adopting the above scheme, the cylinder 21 is driven downward through the connecting frame 34 and the clamp 35 by running the hydraulic rod 32 and under the limit of the limit rod 33, the support assembly 23 will first contact the top of the storage barrel 6, and the spring 24 will be compressed and the pressure sensor 2 42 will be subjected to pressure. When the bottom of the pressure sensor 1 41 contacts the bottom of the storage barrel 6 and is subjected to pressure, the control assembly 43 controls the motor 25 to operate, and the motor 25 drives the conveying roller 26 to rotate through the reduction gear set 251 to convey the powdered drug excipients inside the cylinder 21 to the inside of the storage barrel 6 through the cylinder 21. At the same time, the control assembly 43 also controls the hydraulic rod 32 to extend and drive the cylinder 21 upward, so that the feeding mechanism 2 slowly conveys and accumulates the powdered drug excipients from the bottom of the storage barrel 6, thereby avoiding the direct fall of the powdered drug excipients and causing the powdered drug excipients to be dispersed and wasteful.

[0038] It is worth noting that when the device is reset, that is, when the cylinder 21 moves in the reverse direction so that the spring 24 releases the pressure on the second pressure sensor 42, the control component 43 controls the motor 25 to stop running.

[0039] like Figure 1 and Figure 3-Figure 7 As shown, the outer part of the cylinder 21 is also movably sleeved with a sealing component 5 for connecting the feeding port 211 with the outside when the feeding mechanism 2 moves downward;

[0040] The sealing assembly 5 includes a sleeve 51 movably sleeved on the outside of the cylinder 21, and the sleeve 51 is also movably sleeved inside the spring 24. The outer circumferential annular array of the sleeve 51 is provided with vertical grooves 52 and oblique grooves 53. The bottom ends of the same group of vertical grooves 52 are connected to the top ends of the oblique grooves 53. The bottom circumferential array of the sleeve 51 is provided with a second discharge port 54 which is misaligned with the first discharge port 211 in the initial state. The support assembly 23 is movably sleeved on the outside of the sleeve 51.

[0041] The support assembly 23 is also fixed with a convex shaft 27 that can slide in the vertical groove 52 and the inclined groove 53. The end of the convex shaft 27 is located at the bottom end of the inclined groove 53 in the initial state.

[0042] By adopting the above scheme, when the cylinder 21 is reset and moved upward, the convex shaft 27 is moved from the vertical groove 52 to the top of the inclined groove 53. At this time, the convex shaft 27 will move along the corrugated groove 531 and to the bottom of the inclined groove 53. In this process, the sleeve 51 will rotate, and the connection between the discharge port 1 211 and the discharge port 2 54 will gradually decrease until the two are completely misaligned. At the same time, when the convex shaft 27 moves along the corrugated groove 531, the sleeve 51 will vibrate and transmit the vibration to the cylinder 21, thereby shaking off the powdered drug excipients remaining at the discharge port 1 211 and the discharge port 2 54 to avoid residue.

[0043] like Figure 4 As shown, the support assembly 23 includes a connecting ring 231 movably mounted on the outside of the sleeve 51 and a supporting ring 232 whose bearing is connected to the outside of the connecting ring 231, and the pressure sensor 2 42 is mounted on the connecting ring 231;

[0044] A rubber ring 2321 is fixedly mounted at the bottom of the support ring 232. The rubber ring 2321 is funnel-shaped. The top diameter of the rubber ring 2321 is larger than the inner diameter of the storage barrel 6, and the bottom diameter of the rubber ring 2321 is smaller than the inner diameter of the storage barrel 6.

[0045] By adopting the above solution, by setting the rubber ring 2321 at the bottom of the support ring 232, when the bottom of the support ring 232 abuts against the top of the storage barrel 6 through the rubber ring 2321, it can avoid the two from slipping when they are in contact.

[0046] like Figure 4 and Figure 7 As shown, a corrugated groove 531 communicating with the inclined groove 53 is provided on the lower side of the inner wall of the inclined groove 53; when the sleeve 51 moves upward, the convex shaft 27 can slide along the corrugated groove 531;

[0047] The first feeding port 211 is also fixedly connected with an elastic sheet 212, which is arc-shaped and protrudes toward the conveying roller 26; when the conveying roller 26 rotates, its bottom can squeeze the elastic sheet 212;

[0048] By adopting the above scheme, the bottom end of the conveying roller 26 will intermittently squeeze each group of elastic sheets 212 through the rotation of the conveying roller 26. When the powdered drug excipients pass through the discharge port 211, the elastic sheets 212 will reset under their own elastic force after being squeezed, thereby avoiding the situation where the drugs accumulate at the discharge port 211 and cannot be discharged.

[0049] The working principle and use process of the present invention:

[0050] The storage barrel 6 is conveyed to the bottom of the feeding mechanism 2 through the conveying mechanism 1, and then the powdered drug excipients are conveyed to the inside of the cylinder 21 through the feeding port 22. The hydraulic rod 32 is operated and the cylinder 21 is driven downward through the connecting frame 34 and the clamp 35 under the limit of the limit rod 33. The support component 23 will first abut against the top of the storage barrel 6. At the same time, the spring 24 will be compressed and the pressure sensor 2 42 will be subjected to pressure. When the bottom of the pressure sensor 1 41 contacts the bottom of the storage barrel 6 and is subjected to pressure, the control component 43 controls the motor 25 to operate. The motor 25 drives the conveying roller 26 to rotate through the reduction gear set 251 to convey the powdered drug excipients inside the cylinder 21 to the storage barrel 6 through the cylinder 21. At the same time, the control component 43 will also control the hydraulic rod 32 to extend and drive the cylinder 21 upward, so that the feeding mechanism 2 slowly conveys and accumulates the powdered drug excipients from the bottom of the storage barrel 6, thereby avoiding the direct fall of the powdered drug excipients and causing the powdered drug excipients to be dispersed and wasted.

[0051] When the cylinder 21 moves downward, the support ring 232 on the support assembly 23 will abut against the top of the storage barrel 6. At this time, the support assembly 23 as a whole will maintain a relative height unchanged. The cylinder 21 continues to move downward and drives the sleeve 51 downward. Relatively, at this time, the convex shaft 27 will abut against the inner wall of the upper inclined groove 53 and move upward along the inclined groove 53. At this time, the sleeve 51 will rotate, thereby driving the second discharge port 54 to rotate and gradually communicate with the first discharge port 211. When the convex shaft 27 moves along the vertical groove 52, the second discharge port 54 is continuously connected with the first discharge port 211.

[0052] When the cylinder 21 is reset and moves upward, when the convex shaft 27 moves from the vertical groove 52 to the top of the inclined groove 53, the convex shaft 27 will move along the corrugated groove 531 to the bottom of the inclined groove 53. In this process, the sleeve 51 will rotate, and the connection between the discharge port 1 211 and the discharge port 2 54 will gradually decrease until the two are completely misaligned. At the same time, when the convex shaft 27 moves along the corrugated groove 531, the sleeve 51 will vibrate and transmit the vibration to the cylinder 21, thereby shaking off the powdered drug excipients remaining at the discharge port 1 211 and the discharge port 2 54 to avoid residue.
