Description

Technical Field

[0001] This utility model relates to the field of hydrogel dressing production technology, and in particular to a device for producing hydrogel dressings. Background Technology

[0002] Hydrogel dressings can adhere to the wound surface to create a moist environment, effectively absorb exudate, lock in moisture, relieve pain, reduce friction and irritation, inhibit bacterial growth and prevent infection, and promote epithelial cell growth to accelerate wound healing. They are suitable for various wounds such as burns, abrasions, and chronic ulcers. They are breathable, hypoallergenic, easy to peel off without damaging new tissue, and are a commonly used high-quality dressing for clinical and daily wound care.

[0003] Existing mixing equipment can only achieve single horizontal or vertical rotation. Horizontal rotation is prone to causing raw material stratification and bottom sedimentation, while vertical rotation is difficult to break up powder agglomerates, resulting in insufficient mixing uniformity. At the same time, a single motion trajectory cannot adapt to the density differences and solubility characteristics of the multiple components of hydrogel, which can easily lead to problems such as uneven local concentration and residual air bubbles, affecting the subsequent molding and curing effects and making it difficult to meet the needs of large-scale, high-quality production of hydrogel dressings. In response to the technical problem of uneven mixing, this application proposes a device for producing hydrogel dressings. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of uneven mixing in existing technologies by proposing a hydrogel dressing production device. This device drives a stirring rod to rotate synchronously in both horizontal and vertical directions. Vertical rotation effectively breaks up powder agglomerates and eliminates raw material lumps, while horizontal rotation promotes full convection of the raw materials from top to bottom and inside to outside, preventing stratification and sedimentation caused by density differences. This significantly improves the uniformity of mixing multi-component raw materials, reduces residual air bubbles, shortens mixing time, and is suitable for the production needs of multiple hydrogel dressing formulations and high-quality products, ensuring consistent viscosity and performance of the finished product.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A device for producing hydrogel dressings includes a tank. A motor is fixedly connected to the right side of the top of the tank. A stirring assembly is provided at the drive end of the motor for mixing materials. A sieve frame is fixedly connected to the left side of the top of the tank. A motor is fixedly connected to the right end of the sieve frame. A screen is connected to the drive end of the motor via the sieve assembly for sieving the raw materials. The outer wall of the screen is slidably connected to the inner wall of the sieve frame. A discharge valve is fixedly connected to the lower side of the inner wall of the tank.

[0006] Furthermore, the stirring assembly includes a rotating rod rotatably connected to the inner wall of the tank, and multiple stirring rods are rotatably connected to the inner wall of the rotating rod, with a main bevel gear fixedly connected to one end of each stirring rod.

[0007] Furthermore, a fixing rod is fixedly connected to the inner wall of the tank, and multiple secondary bevel gears are fixedly connected to the outer wall of the fixing rod. The outer walls of the secondary bevel gears are all meshed with the outer walls of the main bevel gears.

[0008] Furthermore, a gear is fixedly connected to the drive end of the motor, and a gear ring is meshed with the outer wall of the gear, with the inner wall of the gear ring fixedly connected to the outer wall of the rotating rod.

[0009] Furthermore, the screening assembly includes a raised wheel fixedly connected to a drive end of the motor, and the outer wall of the raised wheel is disposed at the bottom end of the screen.

[0010] Furthermore, springs are fixedly connected to both sides of the bottom end of the screen, and the other end of each spring is fixedly connected to the inner wall of the screening frame.

[0011] Furthermore, a rotating handle is rotatably connected to the inner wall of the screening frame, a threaded rod is fixedly connected to the bottom end of the rotating handle, a baffle is threadedly connected to the outer wall of the threaded rod, and the outer wall of the baffle is slidably connected to the inner wall of the screening frame.

[0012] This utility model has the following beneficial effects: 1. In this utility model, the stirring rod can be driven to rotate synchronously in the horizontal and vertical directions. The vertical rotation can effectively disperse powder agglomerates and break up raw material lumps, while the horizontal rotation can promote full convection of raw materials from top to bottom and inside to outside, avoiding stratification and sedimentation caused by density differences. This greatly improves the mixing uniformity of multi-component raw materials, while reducing residual air bubbles, shortening mixing time, and adapting to the high-quality production needs of multiple formulations of hydrogel dressings, ensuring the consistency of viscosity and performance of the finished product.

[0013] 2. In this utility model, by screening the raw materials before mixing, impurities, hard lumps and agglomerates in the powder can be removed in advance, so that the raw materials are in a uniform fine powder state, reducing the resistance to subsequent stirring and dispersion, avoiding large particles or impurities from affecting the uniformity of mixing and the purity of the finished product, and helping to improve the consistency of product performance and production efficiency.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0017] Reference Figures 1-3 As shown, one embodiment of this utility model provides a hydrogel dressing production device, including a tank 1. A motor 2 is fixedly connected to the right side of the top of the tank 1. A rotating rod 5 is rotatably connected to the inner wall of the tank 1. Multiple stirring rods 6 are rotatably connected to the inner wall of the rotating rod 5. A main bevel gear 7 is fixedly connected to one end of each stirring rod 6. A fixing rod 8 is fixedly connected to the inner wall of the tank 1. Multiple secondary bevel gears 9 are fixedly connected to the outer wall of the fixing rod 8. The outer walls of the secondary bevel gears 9 are meshed with the outer walls of the main bevel gears 7. A gear 3 is fixedly connected to the drive end of the motor 2. A gear ring 4 is meshed with the outer wall of the gear 3. The inner wall of the gear ring 4 is fixedly connected to the outer wall of the rotating rod 5 for mixing materials.

[0018] Specifically, a controller is installed at the front end of the tank 1. The controller is electrically connected to motor 12 and motor 23. By driving the stirring rod 6 to rotate synchronously in the horizontal and vertical directions, the vertical rotation can effectively break up powder agglomerates and remove raw material lumps. The horizontal rotation can also promote full convection of the raw materials from top to bottom and inside to outside, avoiding stratification and sedimentation caused by density differences. This greatly improves the uniformity of mixing multi-component raw materials, while reducing residual air bubbles, shortening the mixing time, and adapting to the high-quality production needs of multiple formulations of hydrogel dressings, ensuring the consistency of viscosity and performance of the finished product.

[0019] Reference Figures 4-6 As shown, a screening frame 11 is fixedly connected to the top left side of the tank body 1, and a motor 12 is fixedly connected to the right end of the screening frame 11. The outer wall of the screen 14 is slidably connected to the inner wall of the screening frame 11. A discharge valve 10 is fixedly connected to the lower side of the inner wall of the tank body 1. Multiple raised wheels 13 are fixedly connected to the drive end of the motor 12. The outer walls of the raised wheels 13 are all set at the bottom end of the screen 14. Springs 15 are fixedly connected to both sides of the bottom end of the screen 14. The other end of the springs 15 is fixedly connected to the inner wall of the screening frame 11. A rotating handle 16 is rotatably connected to the inner wall of the screening frame 11. A threaded rod 17 is fixedly connected to the bottom end of the rotating handle 16. A baffle 18 is threadedly connected to the outer wall of the threaded rod 17. The outer wall of the baffle 18 is slidably connected to the inner wall of the screening frame 11 for screening raw materials.

[0020] Specifically, by increasing the height of the screening frame 11, the screen 14 can be prevented from shaking the raw materials upwards during vibration. The screen 14 is made of stainless steel. By screening the raw materials before mixing, impurities, hard lumps and agglomerates in the powder can be removed in advance, so that the raw materials are in a uniform fine powder state, reducing the resistance to subsequent stirring and dispersion, and avoiding large particles or impurities from affecting the uniformity of mixing and the purity of the finished product, thus helping to improve the consistency of product performance and production efficiency.

[0021] Working principle: First, raw materials are added to the screening frame 11, and the controller starts motor 12. Motor 12 drives the convex wheel 13 to rotate, pushing the screen 14 upward. The spring 15 drives the screen 14 to vibrate repeatedly, screening the raw materials. Qualified materials are discharged downward and moved into the tank 1. Larger impurities will remain on the surface of the screen 14. When cleaning is required, the handle 16 is manually turned. The handle 16 drives the threaded rod 17 to rotate, and the threaded rod 17 drives the baffle 18 to move upward, thus cleaning the surface of the screen 14. When it is necessary to mix the internal raw materials, motor 2 is started. Motor 2 drives gear 3 to rotate, gear 3 drives the gear ring 4 to rotate, gear ring 4 drives the rotating rod 5 to rotate, and drives the stirring rod 6 on the inner wall to rotate horizontally. At the same time, the main bevel gear 7 rotates on the outer wall of the secondary bevel gear 9, thereby driving the stirring rod 6 to rotate vertically, mixing the raw materials. After mixing is completed, the raw materials are discharged through the discharge valve 10.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
