Description

Technical Field

[0001] The present application relates to the technical field of medical lubricant production, and in particular to a lubricant preparation device. Background Art

[0002] Medical lubricant is a product widely used in the medical and health care fields. It is mainly used to reduce friction, provide lubrication, and protect the skin and mucous membranes under certain circumstances. Raw material stirring is an indispensable step in the production process of medical lubricants. Therefore, the stirring mechanism is a common component in the lubricant preparation device. However, since the lubricant raw materials have a large viscosity, after the stirring mechanism of the existing preparation device stirs the lubricant raw materials, part of the raw materials will adhere to the inner wall of the stirring device, which is difficult to clean. After a long time, the raw materials attached to the inner wall of the stirring mechanism will solidify, affecting the internal volume of the stirring mechanism and reducing the production efficiency of the lubricant. In addition, it will take a long time to clean the solidified raw materials on the inner wall of the stirring mechanism, so it needs to be improved. Utility Model Content

[0003] In order to improve the convenience of cleaning the raw materials attached to the inner wall of the stirring mechanism and improve the overall preparation efficiency of the lubricant, the present application provides a lubricant preparation device.

[0004] The lubricant preparation device provided in this application adopts the following technical solution:

[0005] A lubricant preparation device comprises a mixing drum, wherein a mixing shaft is rotatably connected inside the mixing drum, a scraper ring is arranged on the inner wall of the mixing drum, the outer wall of the scraper ring abuts against the inner wall of the mixing drum, a driving member is arranged on the top wall inside the mixing drum, the driving member is connected to the scraper ring, and the driving member drives the scraper ring to move along the depth direction of the mixing drum.

[0006] By adopting the above technical solution, in the process of preparing medical lubricating liquid, when the raw material mixing process is completed, the driving part will drive the scraper ring to move along the depth direction of the mixing drum. Since the scraper ring is against the inner wall of the mixing drum, during the movement of the scraper ring, the raw materials attached to the inner wall of the mixing drum will be pushed by the scraper ring to move toward the bottom end of the mixing drum, thereby facilitating the staff to clean the raw materials from the discharge port of the mixing drum, which not only effectively prevents the raw materials from being compacted on the inner wall of the mixing drum, but also improves the cleaning efficiency, thereby speeding up the entire production process.

The shovel plate abuts against the inner wall of the mixing drum, and a first inclined surface is provided on the surface of the shovel plate away from the inner wall of the mixing drum.

[0008] By adopting the above technical solution, during the movement of the scraper ring, due to the presence of the shovel plate and the first inclined surface, the raw materials scraped from the inner wall of the mixing drum will fall off more easily, further improving the convenience of cleaning the raw materials on the inner wall of the mixing drum.

[0009] Optionally, a scraper is provided at the bottom end of the stirring shaft, the scraper is located below the scraper ring, and the scraper is arranged toward the inner wall of the stirring drum.

[0010] By adopting the above technical solution, when the scraper ring runs to the maximum stroke section of the driving part, the scraper can move the raw materials attached to the bottom wall of the scraper ring through the rotation of the stirring shaft, thereby promoting the shedding of the raw materials, and further improving the convenience of cleaning the lubricant raw materials in this application.

[0011] Optionally, a second inclined surface is formed at one end of the scraper away from the stirring shaft, and the surface of the second inclined surface is parallel to the surface of the first inclined surface.

[0012] By adopting the above technical solution and providing a second inclined surface, the scraper can be prevented from colliding with the shovel plate while rotating, thereby improving the safety of the mixing drum of the present application during operation and extending its service life.

[0013] Optionally, a driving hole is opened at the bottom end of the rotating shaft, a rotating member is arranged in the driving hole, an output shaft of the rotating member is arranged in a horizontal direction, and the scraper is connected to the output shaft of the rotating member.

[0014] By adopting the above technical solution, starting the rotating part can drive the scraper to rotate, so that the scraper is converted from a horizontal state to a vertical state, thereby facilitating the staff to clean the scraper, with high flexibility and convenience.

[0015] Optionally, a lifting member is further provided in the driving hole, a piston rod of the lifting member is provided along the length direction of the stirring shaft, and the piston rod of the lifting member is connected to the rotating member.

[0016] By adopting the above technical solution, a lifting member is provided to drive the scraper to lift and lower, so as to prevent the end of the scraper from colliding with the bottom wall of the mixing drum during rotation, thereby protecting the structural safety of the mixing drum and the scraper and extending the service life.

[0017] Optionally, a peripheral wall of the stirring shaft is provided with a clearance groove, the clearance groove is opened along the length direction of the stirring shaft, and the clearance groove is connected to the driving hole.

[0018] By adopting the above technical solution, the opening of the clearance groove facilitates the lifting and rotating of the scraper.

[0019] Optionally, a telescopic groove is provided on the top wall of the give way groove, a baffle is slidably connected in the telescopic groove, one end of the baffle extends out of the telescopic groove and abuts against the scraper, an elastic member is provided in the telescopic groove, the elastic member is connected to the baffle, and the elastic member tends to move the baffle in the direction of extending out of the telescopic groove.

[0020] By adopting the above technical solution, the baffle bar continues to resist the scraper under the action of the elastic member, so the baffle bar can continuously block the give way groove to prevent the raw material from entering the drive hole and causing damage to the lifting or rotating parts, thereby improving the safety of the mixing drum of the present application in the preparation process of medical lubricants and extending its service life.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. After the raw material mixing process is completed, the driving part will drive the scraper ring to move along the depth direction of the mixing drum. Since the scraper ring is against the inner wall of the mixing drum, the raw materials attached to the inner wall of the mixing drum will be pushed by the scraper ring to move toward the bottom of the mixing drum during the movement of the scraper ring, making it easier for the staff to clean the raw materials from the discharge port of the mixing drum, which effectively prevents the raw materials from being hardened on the inner wall of the mixing drum and improves the cleaning efficiency, thereby speeding up the entire production process;

[0023] 2. A scraper that can rotate and rise and fall is provided to facilitate the staff to clean the raw materials attached to the bottom wall of the scraper ring, further reducing the waste of raw materials, speeding up the cleaning efficiency and the overall production efficiency of the medical lubricant.
