Description

Technical Field

[0001] This utility model relates to the field of acetaminophen dihydrocodeine tablet production technology, specifically to a batching device in the production of acetaminophen dihydrocodeine tablets. Background Technology

[0002] Acetaminophen and dihydrocodeine tablets are a compound preparation mainly used to relieve various types of pain. However, its ingredients contain narcotic drugs that are controlled by the state. When using them, medical guidance must be strictly followed. During processing, excipients, fillers, binders, and disintegrants need to be added to the raw materials. Therefore, a mixing device is required to ensure uniform mixing.

[0003] An existing patent (publication number: CN219682337U) discloses a batching device for the production of acetaminophen dihydrocodeine tablets. Through a contact plate, a first motor, and a spring, the contact rod intermittently contacts the first motor. Under the action of the spring's rebound force, the contact plate can drive the connecting column to reciprocate in the vertical direction, and the four rotating rods inside can rotate synchronously, so that the stirring rod plays a stirring role. This allows the raw materials inside the mixing tank to be subjected to forces in multiple directions, thereby improving the mixing effect of the acetaminophen dihydrocodeine tablet raw materials and improving the quality of the subsequent tablet production.

[0004] To address the aforementioned issues, while existing patents have proposed solutions that can effectively mix and stir through the use of components such as contact plates, in practice, the raw materials may separate into layers after being poured in sequentially. This separation results in a longer stirring time, thus affecting the overall processing efficiency and ensuring uniform processing. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Given that the existing technology may result in stratification after the raw materials are poured in sequentially, which leads to a longer stirring time and thus affects the overall processing efficiency, the problem of achieving uniform processing exists.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] The batching device in the production of acetaminophen dihydrocodeine tablets includes a stirring vessel, a feeding hopper is fixedly installed at the bottom of the stirring vessel, and a filter shell is fixedly installed at the top of the stirring vessel. An assembly shell is embedded at the top of the filter shell, and a mixing mechanism is provided inside the assembly shell.

[0009] The mixing mechanism includes a vent pipe that penetrates into the interior of the assembly shell, and a gas delivery pipe extends from the bottom end of the vent pipe. A limit ring is fixedly installed on the outer wall of the end of the gas delivery pipe that penetrates into the vent pipe, and a jet pipe is fixedly installed on the outer wall of the end of the gas delivery pipe that penetrates into the mixing vessel. The outer wall of the jet pipe has jet holes.

[0010] As a further improvement of this utility model: a servo motor is embedded in one side of the outer wall of the assembly shell, and a drive rod is fixedly installed at the power output end of the servo motor.

[0011] As a further improvement of this utility model: a drive gear is fixedly installed at one end of the drive rod, and a driven gear is rotatably connected to the outer wall of the drive gear.

[0012] As a further improvement of this utility model: the gas supply pipe forms an engaging structure with the air inlet pipe through a limiting ring, and the limiting ring and the air inlet pipe form a rotating structure.

[0013] As a further improvement of this utility model: a sealing block is inserted into one side of the top of the filter shell, and a venting mechanism is provided inside the filter shell.

[0014] As a further embodiment of this utility model: the venting mechanism includes a fine filter screen, which is embedded in the bottom of the filter housing, and a high-efficiency filter is fixedly installed on the top of the fine filter screen. A coarse filter screen is embedded on the other side of the top of the filter housing.

[0015] As a further improvement of this utility model: an abutment ring is fixedly installed on the outer wall of the gas delivery pipe near the outer wall of the fine filter screen, and a locking ring is fixedly installed on the outer wall of the end of the gas delivery pipe located inside the filter shell.

[0016] As a further improvement of this utility model: an mounting plate is fixedly installed on the outer wall of the abutment ring, and a soft brush is embedded at the top of the mounting plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model, through the cooperation of a ventilation pipe, a gas delivery pipe, a jet pipe, and a jet hole, uses nitrogen to purge the raw materials. With the help of a servo motor, the gas delivery pipe rotates, which can further improve the comprehensiveness of purging, avoid the low mixing efficiency caused by the separation of raw materials, reduce the mixing time while maintaining the uniformity of mixing, and squeeze out oxygen to combine the raw materials with nitrogen, so as to play an antioxidant and preservation role, and improve the practicality of the batching device.

[0019] 2. This utility model, through the combination of a fine filter, a high-efficiency filter, and a coarse filter, allows nitrogen to escape, preventing excessive internal pressure, while also preventing raw materials from escaping with the gas. In conjunction with the rotation of the gas delivery pipe, the contact ring drives the mounting plate, allowing the soft brush to sweep the fine filter, preventing raw materials from being adsorbed and difficult to detach, thus avoiding waste during discharge, and also preventing blockages that affect gas flow.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0029] Example 1:

[0030] Please see Figures 1-3 This is the first embodiment of the present utility model.

[0031] This embodiment provides a batching device for the production of acetaminophen dihydrocodeine tablets, including a stirring tank 1, a feeding hopper 2 fixedly installed at the bottom end of the stirring tank 1, a filter shell 3 fixedly installed at the top end of the stirring tank 1, an assembly shell 4 embedded at the top end of the filter shell 3, and a mixing mechanism 5 provided inside the assembly shell 4.

[0032] The mixing mechanism 5 includes a vent pipe 501, which is inserted into the interior of the assembly shell 4. A gas delivery pipe 502 extends from the bottom end of the vent pipe 501. A limit ring 503 is fixedly installed on the outer wall of one end of the gas delivery pipe 502 that is inserted into the vent pipe 501. A jet pipe 504 is fixedly installed on the outer wall of one end of the gas delivery pipe 502 that is inserted into the mixing vessel 1. A jet hole 505 is opened on the outer wall of the jet pipe 504.

[0033] Specifically, a servo motor 506 is embedded on one side of the outer wall of the assembly shell 4, and a drive rod 507 is fixedly installed on the power output end of the servo motor 506.

[0034] Furthermore, with the cooperation of the servo motor 506, the mixing mechanism 5 can be automatically driven to work, thereby achieving an automation effect.

[0035] Specifically, a drive gear 508 is fixedly installed at one end of the drive rod 507, and a driven gear 509 is rotatably connected to the outer wall of the drive gear 508.

[0036] Furthermore, the driving gear 508 and the driven gear 509 mesh with each other and are driven by the drive rod 507 to rotate the air pipe 502.

[0037] Specifically, the gas supply pipe 502 forms an engaging structure with the vent pipe 501 through the limiting ring 503, and the limiting ring 503 and the vent pipe 501 form a rotating structure.

[0038] Furthermore, the limiting ring 503 allows the gas supply pipe 502 to rotate stably while preventing it from detaching from the ventilation pipe 501, and at the same time allows nitrogen to be delivered.

[0039] In use, the material is first guided to the bottom of the mixing vessel 1 through the feeding hopper 2. The feeding hopper 2 is equipped with an electrically controlled valve to control the discharge. After the gas supply pipe 502 passes through the assembly shell 4, it is rotated and engaged with the gas supply pipe 502 by the limiting ring 503. Nitrogen is supplied by an external gas supply device and a certain pressure is applied. The gas is then guided through the vent pipe 501 to the jet pipe 504 and sprayed out through the jet hole 505. The jet hole 505 is tilted at a certain angle to the vertical axis of the jet pipe 504, thus creating a certain spray angle. This allows the raw materials to be blown and mixed by collision. The servo motor 506 works to drive the drive rod 507 to rotate. With the cooperation of the drive gear 508 and the driven gear 509, the gas supply pipe 502 drives the jet pipe 504 to rotate, thereby further improving the mixing effect.

[0040] In summary, nitrogen is supplied into the ventilation pipe 501 through the cooperation of external gas supply equipment, compression equipment, and nitrogen generator equipment. This is existing technology and will not be described in detail here. Subsequently, through the cooperation of the gas delivery pipe 502, the jet pipe 504, and the jet hole 505, the nitrogen blows the raw material. Driven by the servo motor 506, the motor can rotate during the jetting process. With a jetting angle of 45°~60°, the raw material can be further blown and mixed by collision, which further improves the mixing efficiency and avoids the formation of accumulation and stratification, which would lead to slow mixing.

[0041] Example 2:

[0042] Please see Figure 1 , Figure 4 and Figure 5 This is the second embodiment of the present utility model.

[0043] Specifically, a sealing block 6 is inserted into one side of the housing 4 mounted on the top of the filter housing 3, and an air venting mechanism 7 is provided inside the filter housing 3.

[0044] Furthermore, the sealing block 6 is threadedly connected to the filter shell 3, facilitating the disassembly and assembly of raw materials into the mixing vessel 1.

[0045] Specifically, the venting mechanism 7 includes a fine filter 701, which is embedded in the bottom of the filter housing 3. A high-efficiency filter 702 is fixedly installed on the top of the fine filter 701, and a coarse filter 703 is embedded on the other side of the housing 4 mounted on the top of the filter housing 3.

[0046] Furthermore, when the raw material flies upward, the fine filter 701 and the high-efficiency filter 702 work together to prevent the raw material from overflowing and allow the gas to flow out, thus preventing excessive internal air pressure. In addition, the coarse filter 703 works together to prevent external dust from adhering to the high-efficiency filter 702 and affecting the gas flow.

[0047] Specifically, an abutment ring 704 is fixedly installed on the outer wall of the gas pipe 502 near the outer wall of the fine filter screen 701, and a locking ring 705 is fixedly installed on the outer wall of the end of the gas pipe 502 located inside the filter shell 3.

[0048] Furthermore, through the cooperation of the contact ring 704 and the engaging ring 705, it can engage with the fine filter screen 701, maintaining the stability of the air supply pipe 502 during rotation.

[0049] Specifically, an mounting plate 706 is fixedly installed on the outer wall of the contact ring 704, and a soft brush 707 is embedded at the top of the mounting plate 706.

[0050] Furthermore, driven by the contact ring 704, the mounting plate 706 can drive the soft brush 707 to rotate and adhere to the fine filter screen 701, brushing away the adsorbed raw materials and avoiding waste.

[0051] In use, when gas enters the mixing tank 1 to purge the raw materials, it is filtered by the fine filter 701 and the high-efficiency filter 702 before being discharged, thus preventing excessive air pressure inside the mixing tank 1. It also works with the coarse filter 703 to externally filter and protect the high-efficiency filter 702, preventing the adsorption of dust and other substances that may affect the flow of gas. The gas delivery pipe 502 rotates stably along the fine filter 701 via the contact ring 704 and the locking ring 705, and can drive the mounting plate 706 to allow the soft brush 707 to brush the fine filter 701.

[0052] In summary, the combination of fine filter 701, high-efficiency filter 702, and coarse filter 703 can filter the gas to prevent dust from escaping, prevent excessive air pressure inside the mixing vessel 1, and achieve the effect of venting. It can also prevent external dust from adsorbing onto the high-efficiency filter 702 and affecting gas flow. The rotation of the gas delivery pipe 502, in conjunction with the contact ring 704 and the locking ring 705, keeps it stable. The mounting plate 706 can drive the soft brush 707 to brush the fine filter 701, preventing raw materials from being adsorbed and difficult to remove, thus avoiding waste during later discharge, or blockage that affects gas flow.
