Description

Technical Field

[0001] This utility model relates to the field of drug plate separation technology, specifically a mechanical drug plate quantitative separation device. Background Technology

[0002] Blister packaging is one of the main forms of pharmaceutical packaging, suitable for automated packaging of dosage forms such as tablets, capsules, pills, suppositories, and inhalation powders. It involves first forming a blister by heat or cold processing a rigid substrate, then filling the blister with the medicine, and finally sealing the covering material and the blister material (blister material) with heat to form a pharmaceutical packaging system.

[0003] In the tablet production process of the pharmaceutical industry, the tablets produced by the aluminum-plastic composite machine are conveyed one by one into a vertical collection bin via a conveyor belt. Then, under gravity, they fall onto the conveyor belt, where the medication is dispensed into the tablets, completing the filling process before proceeding to the next production operation. However, in actual use, the tablets tend to stack inside the collection bin, relying solely on gravity for descent. The simultaneous falling of a large number of stacked tablets can cause blockages, necessitating a production stoppage for cleaning and resuming operation, thus reducing production efficiency. Furthermore, the tablets fall haphazardly, with uncontrollable speeds. At high speeds, overlapping may occur between tablets, hindering medication dispensing; at lower speeds, large gaps may exist between tablets, causing medication to fall into these gaps, resulting in waste and contamination. Therefore, a mechanical tablet quantitative separation device is needed to address these problems. Utility Model Content

[0004] The purpose of this invention is to provide a mechanical blister pack quantitative separation device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mechanical blister pack quantitative separation device, comprising two vertical frames, with a fixed frame fixedly installed on the outside of the two vertical frames, a motor fixedly installed inside the fixed frame, a gear one fixedly installed at the output end of the motor, a rotating shaft rotatably installed inside the fixed frame, a gear two fixedly installed outside the rotating shaft, a limiting post fixedly installed at the top of the rotating shaft, a baffle one inserted into the outside of the limiting post, a washer ring inserted into the outside of the limiting post, an insert block inserted into the inside of the limiting post, and a baffle two fixedly installed at the top of the insert block.

[0006] Preferably, the second baffle and the washer ring are in contact with the adjacent surfaces of the first baffle and are arranged in order from top to bottom, and both the first baffle and the second baffle are provided with bevels.

[0007] Preferably, the limiting post is located at the top of the fixed frame, and the second gear meshes with the first gear.

[0008] Preferably, a threaded rod is installed on the internal thread of the rotating shaft, a pressure block is fixedly installed on the external side of the threaded rod, a cam is fixedly installed on the bottom of the rotating shaft, and a rectangular plate is fixedly installed between the two vertical frames.

[0009] Preferably, the cam contacts the rectangular plate, and both the insert block and the second baffle have through holes inside, with the threaded rod passing through the through holes.

[0010] Preferably, the pressure block is pressed against the top of the second baffle, and the cam is located below the fixed frame.

[0011] Compared with the prior art, this utility model provides a mechanical blister pack quantitative separation device, which has the following beneficial effects:

[0012] 1. This mechanical blister pack quantitative separation device supports the bottom of the blister packs using a pair of baffles. A rotating shaft drives baffles one and two to rotate synchronously. When baffle one rotates 180 degrees and completely detaches from the blister pack, it no longer obstructs the blister pack. At this point, the blister pack falls under the influence of gravity, facilitating the next production operation. This ensures that the stacked blister packs fall evenly, allowing control over the spacing between the two blister packs. This avoids the problems of disordered falling, uncontrollable falling speed, overlapping of the two blister packs at high speeds causing inconvenience in drug dispensing, and large gaps between the two blister packs at low speeds, which could lead to waste and contamination of the medicine.

[0013] 2. Based on this, the present invention uses a cam to strike a rectangular plate, causing two vertical frames to vibrate, so that the blister pack that has detached from the first baffle falls smoothly under the action of gravity, thus preventing the blister pack from getting stuck inside the two vertical frames.

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.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] Example 1:

[0024] Please see Figure 1-5 This utility model provides a technical solution: a mechanical blister pack quantitative separation device, including two vertical frames 1, a fixed frame 2 fixedly installed on the outside of the two vertical frames 1, a servo motor 3 fixedly installed inside the fixed frame 2, a gear 4 fixedly installed at the output end of the servo motor 3, a rotating shaft 5 rotatably installed inside the fixed frame 2, a gear 6 fixedly installed on the outside of the rotating shaft 5, a limiting post 7 fixedly installed on the top of the rotating shaft 5, a baffle 8 inserted into the outside of the limiting post 7, a washer 9 inserted into the outside of the limiting post 7, an insert block 10 inserted into the inside of the limiting post 7, and a baffle 11 fixedly installed on the top of the insert block 10 to facilitate the covering of the blister pack.

[0025] Furthermore, the adjacent surfaces of the second baffle 11, the gasket 9, and the first baffle 8 are in contact and arranged sequentially from top to bottom. Both the first baffle 8 and the second baffle 11 are provided with bevels to facilitate the blister pack sliding down the top of the second baffle 11.

[0026] Furthermore, the limiting post 7 is set at the top of the fixed frame 2, and the second gear 6 meshes with the first gear 4, driving the rotating shaft 5 to rotate.

[0027] Example 2:

[0028] Please see Figure 5 Furthermore, in conjunction with Embodiment 1, it is further found that the internal thread of the rotating shaft 5 is fitted with a threaded rod 12, the external thread of the threaded rod 12 is fixedly fitted with a pressure block 13, the bottom of the rotating shaft 5 is fixedly fitted with a cam 14, and a rectangular plate 15 is fixedly fitted between the two vertical frames 1 to facilitate the vibration of the two vertical frames 1 in cooperation with the cam 14.

[0029] Furthermore, the cam 14 contacts the rectangular plate 15, and the insert block 10 and the second baffle 11 are both provided with through holes. The threaded rod 12 passes through the through holes, so that the threaded rod 12 can be threaded into the inside of the rotating shaft 5 to drive the pressure block 13 down, so that the second baffle 11, the washer ring 9 and the first baffle 8 are all installed.

[0030] Furthermore, the pressure block 13 presses against the top of the baffle plate 11, and the cam 14 is set below the fixed frame 2. The cam 14 strikes the rectangular plate 15, causing the two vertical frames 1 to vibrate, which facilitates the falling of the blister pack.

[0031] In actual operation, when this device is in use, the top of the conveyor belt is flush with the bottom of the entrance positions of the two vertical frames 1. The conveyor belt carries the finished frothing medicine plates through the entrances of the two vertical frames 1 into the space between the two vertical frames 1. Initially, baffle plate 1 8 is positioned to the left of baffle plate 2 11, and the bottom frothing medicine plate abuts against the top of the part of baffle plate 1 8 that extends into the vertical frame 1. Then, the servo motor 3 is started, driving gear 1 4 to rotate. Gear 2 6 meshes with gear 1 4, driving the rotating shaft 5 to rotate, causing the limiting post 7 to rotate, causing baffle plate 1 8 and baffle plate 2 11 to rotate synchronously. This allows baffle plate 1 8 to move at the bottom of the frothing medicine plate. Under the action of the washer ring 9, there is a gap between baffle plate 2 11 and baffle plate 1 8. As baffle plate 1 8 continues to rotate, the frothing medicine plate enters the gap between baffle plate 1 8 and baffle plate 2 11. After plate 8 rotates 180 degrees and completely detaches from the blister pack, it no longer blocks the bottom blister pack. At this point, the blister pack falls under gravity, facilitating the next production operation. Simultaneously, baffle plate 2 11 is positioned above the original position of baffle plate 8, blocking the second-to-last blister pack. As the rotating shaft 5 continues to rotate, the second-to-last blister pack abuts against the top of baffle plate 8. Repeating the above operation ensures that the stacked blister packs fall evenly, allowing control over the spacing between the two blister packs. This avoids disordered falling of the packs, uncontrollable falling speed, and the possibility of overlapping sections when falling too quickly, causing inconvenience in drug dispensing, or large gaps between the packs when falling too slowly, which could lead to waste and contamination of the drug.

[0032] Furthermore, a cam 14 is fixed at the bottom of the rotating shaft 5. When the baffle plate 8 rotates to the point of detaching from the blister pack, the cam 14 strikes the rectangular plate 15, causing the two vertical frames 1 to vibrate. This allows the blister pack detached from the baffle plate 8 to fall smoothly under the action of gravity, avoiding the problem of blockage between the two vertical frames 1. Moreover, the baffle plate 8 is prone to static electricity and adhesion when it rubs against the blister pack. The vibration also prevents the blister pack from being stuck to the outside of the baffle plate 8 due to static electricity and making it difficult to fall.

[0033] Furthermore, the gasket 9 can be adjusted and replaced according to the thickness of the blister pack. When replacing it, the threaded rod 12 is threaded inside the rotating shaft 5, which drives the pressure block 13 to move upward and disengage from the top of the baffle plate 11. When the threaded rod 12 disengages from the rotating shaft 5, the threaded rod 12 can be pulled out of the through hole of the baffle plate 11. Then, the baffle plate 11 is pulled up so that the insert block 10 disengages from the limit post 7, allowing the gasket 9 to be exposed. The gasket 9 can then be removed for replacement, making it more flexible and easier to maintain when the baffle plate 8 and the baffle plate 11 are worn.

[0034] It should be added that when the insert 10 is inserted into the limit post 7, the threaded rod 12 is passed through the through hole of the second baffle 11 and the insert 10, and then the threaded rod 12 is rotated and threaded into the inside of the rotating shaft 5, so that the pressure block 13 descends until it is pressed against the top of the second baffle 11, so that the second baffle 11, the washer 9 and the first baffle 8 are all installed.

[0035] It should be added that the two vertical frames 1 can be assembled and installed above the drug dispensing conveyor belt to facilitate drug dispensing after the blister packs have fallen.

[0036] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
