Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical raw material processing and mixing technology, and in particular to a device for uniformly mixing pharmaceutical patch raw materials and excipients. Background Technology

[0002] In the manufacturing process of medical patches, the active pharmaceutical ingredients (APIs) and excipients need to be mixed evenly. By mixing the APIs and excipients evenly, it can be ensured that the APIs in the patch can be released stably and continuously during the release process, thereby improving the stability of the drug efficacy and the treatment effect on patients.

[0003] Traditional mixing devices typically involve sequentially pouring multiple raw materials into the mixing device through the feed inlet and then mixing them. However, this sequential pouring of raw materials can cause them to accumulate in layers, which reduces the mixing efficiency of the device.

[0004] Therefore, those skilled in the art have provided a device for uniformly mixing pharmaceutical raw materials and excipients in a medical patch to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for uniformly mixing pharmaceutical raw materials and excipients in a pharmaceutical patch. By designing four feeding troughs at the top of the mixing tank, with the bottom of each feeding trough connected to the inside of the mixing tank, multiple raw materials can be fed simultaneously. Before feeding, the drive motor is turned on, and the multiple raw materials are dispersed and mixed during the feeding and falling process, avoiding the situation of multiple raw materials stratifying and accumulating, thus improving the mixing efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A device for uniformly mixing pharmaceutical patch raw materials and excipients includes a frame plate. A mixing tank is integrally mounted on the top center of the frame plate. A feeding trough is provided at each of the four corners of the top of the mixing tank. The bottom end of each feeding trough is connected to the interior of the mixing tank. A drive motor is installed at the top center of the mixing tank. A plurality of first stirring shafts are integrally mounted on the output end of the drive motor. A plurality of stirring blades are provided on the outer end of each first stirring shaft. A plurality of through holes are provided on the surface of each stirring blade. A plurality of second stirring shafts of different lengths are provided on the lower half of the output end of the drive motor. The lengths of the plurality of second stirring shafts decrease sequentially from top to bottom.

[0008] The above technical solution involves designing four feeding troughs at the top of the mixing tank, with the bottom of each trough connected to the inside of the mixing tank. This allows for the simultaneous addition of multiple raw materials. Before adding the materials, the drive motor is turned on, and the materials are dispersed and mixed as they fall, preventing the accumulation of multiple materials in layers and improving mixing efficiency. The design of the first and second stirring shafts, stirring blades, and through holes facilitates the mixing of multiple materials.

[0009] Furthermore, a retaining frame is fixedly installed at the bottom of the mixing tank. The two ends of the retaining frame are designed to rotate. A locking bolt is installed at the interface of the retaining frame. The locking bolt is matched with a locking nut. A retaining ring is integrally provided on the inner side of the retaining frame.

[0010] The above technical solution involves fixing a retaining frame at the bottom of the mixing tank. The two ends of the retaining frame are designed to rotate. A retaining ring is integrally set on the inner side of the retaining frame, which engages with the annular groove on the side of the bottom cover to initially fix the bottom cover. Then, the retaining frame is locked by the locking bolt installed at the interface of the retaining frame, thereby further fixing the bottom cover. This part of the design is simple and convenient for installing and removing the bottom cover.

[0011] Furthermore, a bottom cover is fitted inside the card frame, and an annular slot is formed on the side wall of the bottom cover;

[0012] The above technical solution provides a bottom cover inside the card frame to facilitate sealing the outlet of the mixing tank, and an annular groove is provided on the side wall of the bottom cover to facilitate its snap-fit ​​and fixation with the card frame.

[0013] Furthermore, each of the feeding troughs is topped with a top cover, and each top cover is integrally provided with a handle at its top.

[0014] With the above technical solution, each feeding trough is equipped with a top cover to facilitate sealing the feeding trough, and each top cover is integrated with a handle to facilitate picking up the top cover.

[0015] Furthermore, a control panel is installed on one side of the top of the frame plate, and the control panel is electrically connected to the drive motor;

[0016] With the above technical solution, a control panel is installed on one side of the top of the frame plate. The control panel is electrically connected to the drive motor, which facilitates the control of the entire device.

[0017] Furthermore, a fixing frame is installed at the output end of the drive motor, and one side of the fixing frame is in contact with the inner wall of the mixing tank;

[0018] With the above technical solution, a fixing frame is installed at the output end of the drive motor. One side of the fixing frame is attached to the inner wall of the mixing tank, so that the raw materials on the inner wall of the tank can be scraped off, thus preventing the raw materials from accumulating on the inner wall of the tank during the mixing process.

[0019] Furthermore, support legs are fixedly installed at the four corners of the bottom end of the frame plate;

[0020] With the above technical solution, support legs are fixedly installed at the four corners of the bottom of the frame to facilitate the support of the entire device.

[0021] This utility model has the following beneficial effects:

[0022] 1. The present invention proposes a device for uniformly mixing raw materials and excipients for pharmaceutical patches.
