Detailed Implementation
[0020] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example 1
[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a mixing device for producing matte PET composite medical wound dressing, comprising: a mixing box 1, rotating blocks 2 installed on both side walls of the mixing box 1, a support frame 3 connected to the side wall of the rotating blocks 2, a movable groove 4 opened at the bottom center of the support frame 3, and a stabilizing component 5 installed inside the movable groove 4;
[0022] The stabilizing component 5 includes a movable rod 6, a support plate 7 is installed on the outer surface of the movable rod 6, a slot 8 is opened on the side wall of the support plate 7, the top of the support plate 7 is an L-shaped ring and is located at the bottom of the mixing box 1, the top of the mixing box 1 is provided with a feed inlet 20, and the bottom of the outer end side wall of the discharge pipe 17 is provided with a discharge outlet 21.
[0023] In use, the mixing chamber 1 can be easily rotated by the rotating block 2 to make it easy to pour out the mixed medical wound dressing mask. The support frame 3 provides support for the mixing chamber 1. The support plate 7 can be moved to the outermost end of the movable groove 4 through the movable rod 6. The stabilizing component 5 clamps and stabilizes one side of the mixing chamber 1 through the support plate 7, providing stability when mixing inside the mixing chamber 1. Example 2
[0024] Based on Embodiment 1, a structure is provided to enhance the stability of the support plate 7. A pull rod 9 is installed through the side wall of the movable groove 4. A baffle 10 is installed at the inner end of the pull rod 9. The baffle 10 is in contact with the side wall of the support plate 7. A spring 11 is sleeved on the outer surface of the pull rod 9. The spring 11 provides a constant thrust to the baffle 10. One end of the spring 11 is fixed to the side wall of the baffle 10, and the other end of the spring 11 is fixed to the inner wall of the movable groove 4.
[0025] In use, the baffle 10 moves the pull rod 9 inward under the force of the spring 11 to stably support the side wall of the support plate 7. When the support plate 7 is retracted, the pull rod 9 is pulled to make the support plate 7 rotate to a flat position, so that the top of the baffle 10 enters the inside of the slot 8 to fix the support plate 7. Example 3
[0026] Based on Embodiment 2, a structure is provided to facilitate the uniform mixing and transportation of the dressing. A rotating rod 12 is installed through the side wall of the mixing box 1. A drive motor 13 is installed at the side end of the side wall of the rotating rod 12. The drive motor 13 is located on the side wall of the mixing box 1. Several stirring rods 14 are installed on the outer surface of the rotating rod 12. The stirring rods 14 are evenly distributed in an array on the outer surface of the rotating rod 12. A ring plate 15 is installed on the side wall of the stirring rod 14. Several scrapers 16 are installed on the outer wall of the ring plate 15. The outer ends of the scrapers 16 are in contact with the inner wall of the mixing box 1. A discharge pipe 17 is installed at the bottom of the side wall of the mixing box 1. A propeller 18 is installed inside the discharge pipe 17. A power motor 19 is installed on the side wall of the propeller 18. The power motor 19 is located on the side wall of the discharge pipe 17.
[0027] In use, the inside of the mixing chamber 1 is driven by the drive motor 13 to rotate the rotating rod 12, which in turn drives the stirring rod 14 to rotate and stir. The scraper 16 on the outer wall of the ring plate 15 prevents the dressing from sticking to the inner wall of the mixing chamber 1. After being stirred evenly, the dressing is transported to the discharge port 21 by the propeller 18 driven by the power motor 19.
[0028] Working principle: In actual use, the mixing chamber 1 is easily rotated by the rotating block 2 to facilitate the pouring out of the mixed medical wound dressing mask. The support frame 3 provides support for the mixing chamber 1. The support plate 7 moves to the outermost end of the movable groove 4 via the movable rod 6. The stabilizing component 5 clamps and stabilizes one side of the mixing chamber 1 via the support plate 7, providing stability during mixing inside the mixing chamber 1. Under the force of the spring 11, the baffle 10 drives the pull rod 9 to move inward, stabilizing the side wall of the support plate 7. The dressing is poured out from the feed port 2. The dressing is placed inside the mixing chamber 1. The drive motor 13 drives the rotating rod 12 to rotate, which in turn drives the mixing rod 14 to rotate, quickly and evenly mixing the dressing. Pulling the lever 9 allows the support plate 7 to rotate to a flat position, so that the top of the baffle 10 passes into the slot 8 to fix the support plate 7. After the mixing chamber 1 is tilted by the rotating block 2, the scraper 16 on the outer wall of the ring plate 15 prevents the dressing from sticking to the inner wall of the mixing chamber 1. The evenly mixed dressing is transported to the discharge port 21 by the propeller 18 driven by the power motor 19.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
