Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical coating production technology, specifically to an atomizing spray gun for pharmaceutical microcapsule coating. Background Technology

[0002] Drugs refer to substances used to prevent, treat, or diagnose human diseases, or to purposefully regulate human physiological functions, and which have specified indications or functions, usage, and dosage. They include traditional Chinese medicine, chemical drugs, and biological products.

[0003] Drug coating refers to the technology of wrapping a film around the surface of a drug tablet core. It is mainly used to improve the stability of the drug, mask unpleasant odors, control the release site or rate, and improve the appearance.

[0004] Coating machines are used in the process of drug coating. These machines are equipped with atomizing spray guns to atomize and spray the coating liquid, thereby forming a coating layer on the outside of the drug. However, traditional atomizing spray guns are mostly fixed in design. Therefore, when the angle of the atomizing spray gun needs to be adjusted, it needs to be adjusted manually, which reduces the automation level of the machine. At the same time, it is necessary to stop the machine for adjustment, which affects the coating efficiency. To address this, this invention proposes an atomizing spray gun for drug microcapsule coating that can automatically adjust the angle. Utility Model Content

[0005] The purpose of this invention is to provide an atomizing spray gun for microencapsulated pharmaceutical products, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an atomizing spray gun for microencapsulated pharmaceutical products, comprising a fixed base, a motor box fixedly mounted on one side of the outer surface of the fixed base, a steering motor fixedly mounted inside the motor box, a rotating seat fixedly mounted on the top of the output shaft of the steering motor, a rotating seat fixedly mounted on the outer surface of the rotating seat, an inner rotating shaft rotatably mounted between the two rotating seats via a bearing, a rotating block sleeved on the outside of the inner rotating shaft, the inner rotating shaft and the rotating block being fixedly connected, an angle adjusting motor fixedly mounted on the outer wall of one side of the rotating seat, the output shaft of the angle adjusting motor being fixedly connected to the inner rotating shaft, an mounting plate fixedly mounted on the outer wall of the rotating block by welding, and an atomizing spray gun fixedly mounted on the outer wall of the mounting plate by fixing bolts.

[0007] Preferably, the atomizing spray gun is externally fixed with a pipe connector.

[0008] Preferably, a threaded post is fixedly installed at the end of the fixed base away from the motor box, and the threaded post and the fixed base are integrally formed.

[0009] Preferably, the outer surface of the motor box is fixedly mounted with an outer cover by bolts, the output shaft of the steering motor extends through the outer cover, and the output shaft of the steering motor is connected to the outer cover by a bearing.

[0010] Preferably, both the steering motor and the angle adjustment motor are servo motors.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model's atomizing spray gun, in actual use, can achieve left and right angle adjustment through the drive of a steering motor, providing a dynamic left-right adjustment effect. Conversely, through the drive of a set angle adjustment motor, it can achieve up-and-down angle adjustment, providing a dynamic up-and-down angle adjustment effect. The combined use of these two mechanisms allows the atomizing spray gun to automatically adjust in multiple directions (up, down, left, and right), resulting in a wider angle adjustment range. Dynamic angle adjustment ensures more even spraying of the coating liquid, improving the uniformity of drug coating. Furthermore, the motor-driven automatic adjustment eliminates the need for manual adjustment, making angle adjustment more precise and enhancing the overall automation of the coating machine. Simultaneously, it eliminates the need for manual shutdown for adjustment, allowing for automated adjustment during the coating process and ensuring efficient drug coating.

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.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Please see Figure 1-4 An embodiment of this utility model provides a microcapsule coating atomizing spray gun for pharmaceuticals, including a fixed base 1, a motor box 2 fixedly installed on one side of the outer surface of the fixed base 1, a steering motor 3 fixedly installed inside the motor box 2, an outer cover of the box fixedly installed on the outer surface of the motor box 2 by bolts, the output shaft of the steering motor 3 passing through the outer cover of the box, and the output shaft of the steering motor 3 being connected to the outer cover of the box by a bearing, and a rotating seat 4 fixedly installed at the top of the output shaft of the steering motor 3, so that the steering motor 3 can drive the rotating seat 4 to rotate through its output shaft;

[0022] Furthermore, a rotating seat 5 is fixedly installed on the outer surface of the rotating seat 4. An inner rotating shaft 6 is rotatably installed between the two rotating seats 5 via a bearing. A rotating block 7 is sleeved on the outside of the inner rotating shaft 6. The inner rotating shaft 6 is fixedly connected to the rotating block 7. An angle adjustment motor 8 is fixedly installed on the outer wall of one side of the rotating seat 5. The output shaft of the angle adjustment motor 8 is fixedly connected to the inner rotating shaft 6. Thus, the angle adjustment motor 8 can drive the rotating block 7 to rotate through the inner rotating shaft 6. An installation plate 9 is fixedly installed on the outer wall of the rotating block 7 by welding. An atomizing spray gun 10 is fixedly installed on the outer wall of the installation plate 9 by fixing bolts.

[0023] Based on the above structure, when it is necessary to adjust the angle of the atomizing spray gun 10, the angle adjustment motor 8 can be used. When the angle adjustment motor 8 is working, it will drive the inner rotating shaft 6 to rotate in both directions through the output shaft. When the inner rotating shaft 6 rotates under the action of the angle adjustment motor 8, the rotating block 7 fixedly installed on it can rotate synchronously. Thus, the rotation of the rotating block 7 can drive the atomizing spray gun 10 to perform angle adjustment.

[0024] In practical use, when the angle adjustment motor 8 rotates clockwise, it drives the nozzle of the atomizing spray gun 10 to rotate from the upper right to the lower right, thereby adjusting the nozzle angle downwards. When the angle adjustment motor 8 rotates counterclockwise, it drives the nozzle of the atomizing spray gun 10 to rotate from the lower to the upper left, thereby adjusting the nozzle angle downwards. By using the angle adjustment motor 8 in conjunction with the rotating block 7, the atomizing spray gun of this invention has the characteristic of up-and-down angle adjustment, and in practical use, it has the practical characteristic of automatic adjustment of the nozzle angle.

[0025] Meanwhile, this utility model is equipped with a steering motor 3, which can drive the rotating base 4 and its mechanism assembly to rotate clockwise or counterclockwise. When the steering motor 3 rotates clockwise by a certain angle, the nozzle of the atomizing spray gun 10 can face to the right. When the steering motor 3 rotates counterclockwise by 180° when the nozzle of the atomizing spray gun 10 is facing to the right, the nozzle of the atomizing spray gun 10 can be adjusted from right to left, and the nozzle of the atomizing spray gun 10 will face to the left. Thus, through the design of the steering motor 3, the nozzle of the atomizing spray gun 10 can be dynamically adjusted left and right.

[0026] In order to effectively perform servo control on the steering motor 3 and the angle adjustment motor 8, both the steering motor 3 and the angle adjustment motor 8 are servo motors.

[0027] The servo control technology for servo motors is a mature and simple control solution in existing automated industries, and its control principle will not be described in detail in this manual.

[0028] In this embodiment, in order to facilitate the connection of the atomizing spray gun 10 to the external coating liquid supply pipeline, a pipeline connector 12 is fixedly installed on the outside of the atomizing spray gun 10.

[0029] In this embodiment, a threaded post 11 is fixedly installed at the end of the fixed base 1 away from the motor box 2. The threaded post 11 and the fixed base 1 are integrally formed. The threaded post 11 can be used to install the atomizing spray gun assembly of this utility model on the appropriate spray gun bracket by means of threaded installation, thereby ensuring the normal bracket installation and use effect.

[0030] Working principle: When in use, the atomizing spray gun assembly of this utility model can be installed on the appropriate spray gun bracket by means of the threaded post 11, thereby ensuring the normal bracket installation and use effect.

[0031] After the atomizing spray gun assembly is installed on the spray gun bracket via the threaded post 11, the motor and atomizing spray gun 10 can be wired to ensure normal electrical and pipeline connections.

[0032] In actual use, external coating liquid can enter the atomizing spray gun 10 through the pipeline and pipeline connector 12, and be atomized and sprayed out through the atomizing spray gun 10 to ensure normal drug coating effect.

[0033] When the angle of the atomizing spray gun 10 needs to be adjusted, the angle adjustment motor 8 can be used. When the angle adjustment motor 8 is working, it will drive the inner rotating shaft 6 to rotate in both directions through the output shaft. When the inner rotating shaft 6 rotates under the action of the angle adjustment motor 8, the rotating block 7 fixed on it can rotate synchronously. Thus, the rotation of the rotating block 7 can drive the atomizing spray gun 10 to adjust its angle.

[0034] In practical use, when the angle adjustment motor 8 rotates clockwise, it drives the nozzle of the atomizing spray gun 10 to rotate from the upper right to the lower right, thereby adjusting the nozzle angle downwards. When the angle adjustment motor 8 rotates counterclockwise, it drives the nozzle of the atomizing spray gun 10 to rotate from the lower to the upper left, thereby adjusting the nozzle angle downwards. By using the angle adjustment motor 8 in conjunction with the rotating block 7, the atomizing spray gun of this invention has the characteristic of up-and-down angle adjustment, and in practical use, it has the practical characteristic of automatic adjustment of the nozzle angle.

[0035] Meanwhile, this utility model is equipped with a steering motor 3, which can drive the rotating base 4 and its mechanism assembly to rotate clockwise or counterclockwise. When the steering motor 3 rotates clockwise by a certain angle, the nozzle of the atomizing spray gun 10 can face to the right. When the steering motor 3 rotates counterclockwise by 180° when the nozzle of the atomizing spray gun 10 is facing to the right, the nozzle of the atomizing spray gun 10 can be adjusted from right to left, and the nozzle of the atomizing spray gun 10 will face to the left. Thus, through the design of the steering motor 3, the nozzle of the atomizing spray gun 10 can be dynamically adjusted left and right.

[0036] Based on the above comprehensive description, the atomizing spray gun 10 of this utility model, in actual use, can complete the left and right angle adjustment work through the drive of the steering motor 3, and has a dynamic left and right adjustment effect. Through the drive of the angle adjustment motor 8, the atomizing spray gun 10 can complete the up and down adjustment work, and has a dynamic up and down angle adjustment effect. Through the combined use of these two, the atomizing spray gun 10 of this utility model can perform automatic adjustment in multiple directions (up, down, left, right), and the angle adjustment range of the spray gun is wider. Through dynamic angle adjustment, the coating liquid can be sprayed more evenly, improving the uniformity of drug coating. Furthermore, the motor drive enables automated adjustment, eliminating the need for manual adjustment. The angle adjustment is more precise, improving the overall automation effect of the coating machine. At the same time, no manual stopping for adjustment is required; automated drive adjustment can be performed during the coating process, ensuring the coating efficiency of the drug.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
