[0002] Polyethylene glycol (PEG) liquid dressings hold a vital position in the medical field, with a wide range of applications. In wound care, whether it's everyday abrasions and cuts or surgical wounds, PEG liquid dressings are incredibly effective. Their gentle and skin-friendly properties allow them to gently cover the wound surface, forming a protective film that moisturizes and isolates the wound, effectively blocking the invasion of external bacteria and contaminants. Simultaneously, they keep the wound in a moist environment, promoting healing and reducing the likelihood of scarring.

[0003] Polyethylene glycol (PEG) liquid dressings are widely used in wound care and skin treatments due to their excellent biocompatibility, moisturizing properties, and protective effects. To ensure the quality and efficacy of the liquid dressing, various raw materials such as PEG, solvents, and additives must be mixed in precise proportions using mixing equipment.

[0004] However, existing liquid dressing mixing equipment often uses simple mechanical structures. Due to the difficulty in achieving high-precision raw material mixing through mechanization, product quality becomes unstable. Furthermore, during the mixing of raw materials, smaller particles, which contain particles of different sizes, are prone to getting stuck in the feeding channel, leading to blockages during the feeding process. To address these issues, a polyethylene glycol liquid dressing mixing equipment is proposed. Utility Model Content

[0031] 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.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a polyethylene glycol liquid dressing mixing device, comprising a base 1. The base 1 has a flat surface and sufficient strength and stability to ensure that it will not shake or shift during operation. A mixing chamber 2 is fixedly connected to the top of the base 1. The mixing chamber 2, as the core area for raw material mixing, is made of corrosion-resistant stainless steel. Three feed pipes 3 are fixedly connected to the top of the mixing chamber 2, corresponding to polyethylene glycol, solvent, and additives, respectively. The feed pipes 3 are typically made of smooth, wear-resistant, and non-clogging metal or plastic materials to ensure smooth passage of the raw materials. A metering chamber 4 is fixedly connected to the top of the feed pipes 3, used to precisely control the amount of raw materials fed. A first motor 5 is fixedly connected to the side wall of the metering chamber 4. A rotating shaft 6 is fixedly connected to the drive end of the first motor 5. The output shaft of the first motor 5 is fixedly connected to the rotating shaft 6, enabling precise control of the rotation speed and direction of the rotating shaft 6.

[0033] refer to Figure 2 A drive gear 7 is fixedly connected to the end of the rotating shaft 6 away from the first motor 5. The drive gear 7 obtains power by driving the rotating shaft 6 to rotate through the first motor 5, thus initiating its rotation. Multiple partitions 8 are fixedly connected to the outside of the rotating shaft 6. The number of partitions 8 is determined according to the pre-set ratio parameters of polyethylene glycol, solvent, and additive raw materials, and the spacing between each partition 8 is also carefully designed. The outside of the partitions 8 is slidably connected to the inner wall of the metering chamber 4, allowing them to rotate freely within the metering chamber 4 under the drive of the rotating shaft 6. The side of the partition 8 away from the rotating shaft 6 is slidably connected to the top of the feed pipe 3. When the raw material in the feed hopper 9 passes through the partition 8, the partition 8 can guide the raw material sequentially into the corresponding feed pipe 3 according to the set ratio.

[0034] A feeding hopper 9 is fixedly connected to the top of the metering chamber 4. This hopper is used to store raw materials such as polyethylene glycol, solvents, and additives. The material of the feeding hopper 9 should have good chemical stability and corrosion resistance to avoid contamination or reaction of the raw materials. The side of the partition plate 8 away from the rotating shaft 6 is slidably connected to the bottom end of the feeding hopper 9. The bottom opening of the feeding hopper 9 communicates with the top end of the feeding pipe 3 to ensure that the raw materials can smoothly enter the feeding pipe 3. A rotating roller 10 is rotatably connected to the middle of the bottom end of the feeding hopper 9. A driven gear 11 is fixedly connected to the end of the rotating roller 10 near the driving gear 7. The external teeth of the driving gear 7 mesh with the external teeth of the driven gear 11. The top end of the feeding hopper 9 is fixedly connected to the feed pipe 17.

[0035] refer to Figure 3 , Figure 4 A ring rod 12 is fitted in the middle of the rotating roller 10. The front and rear ends of the ring rod 12 are fixedly connected to the bottom of the inner wall of the hopper 9. The rotating roller 10 rotates around its own axis through the rotational power transmitted by the driven gear 11. The ring rod 12 not only supports the rotating roller 10, but also provides guidance for the movement of the anti-blocking hopper 14. A spring rod 13 is fixedly connected to the top of the ring rod 12, and the anti-blocking hopper 14 is fixedly connected to the top of the spring rod 13. The main function of the spring rod 13 is to provide an upward elastic force to the anti-blocking hopper 14, so that the anti-blocking hopper 14 can maintain a certain pressure under the pressure of the material, thereby better crushing and preventing the material from agglomerating.

[0036] A connecting assembly for driving the anti-blocking bucket 14 is provided in the middle of the rotating roller 10. The connecting assembly includes a deflector wheel 15. The middle part of the deflector wheel 15 is fixedly connected to the middle part of the rotating roller 10. The outer part of the deflector wheel 15 is rotatably connected to a connecting sleeve wheel 16. The top end of the connecting sleeve wheel 16 is rotatably connected to the inner top end of the anti-blocking bucket 14. The main function of the deflector wheel 15 is to transmit the rotational power of the rotating roller 10 to the connecting sleeve wheel 16, so that the anti-blocking bucket 14 can move up and down.

[0037] refer to Figure 5 A second motor 18 is fixedly connected to the top right side of the base 1. A stirring frame 19 is fixedly connected to the drive end of the second motor 18. The left and right ends of the stirring frame 19 are rotatably connected to the middle of the mixing chamber 2. The second motor 18 is the power source that drives the stirring frame 19 to rotate. The working principle of the second motor 18 is similar to that of the first motor 5. It obtains power by connecting to an external power source and converts it into mechanical energy output. The power and speed of the second motor 18 can be selected according to the stirring requirements of the raw materials in the mixing chamber 2 to ensure that the raw materials are fully and evenly stirred. A discharge pipe 20 is fixedly connected to the bottom end of the mixing chamber 2 on the side away from the second motor 18. The discharge pipe 20 is used to discharge the stirred polyethylene glycol liquid dressing out of the equipment.

[0038] Working Principle: During operation, the operator adds polyethylene glycol, solvent, and additives to the corresponding feed hoppers 9 as needed. Then, the first motor 5 is started, driving the rotating shaft 6 to rotate the partitions 8 within the metering chamber 4. At this time, the number of partitions 8 on the rotating shaft 6 corresponds to the set ratio parameters of polyethylene glycol, solvent, and additives. Therefore, after the first motor 5 starts and drives the partitions 8 through the rotating shaft 6, the raw materials can be metered and fed into the mixing chamber 2 according to a precise ratio through the feed pipe 3. Inside the mixing chamber 2, the second motor 18 drives the stirring rack 19 to fully mix the raw materials. Finally, the well-mixed raw materials flow out from the discharge pipe 20.

[0039] During the falling of raw materials, the rotating shaft 6 will drive the driving gear 7 to rotate synchronously. After the driving gear 7 rotates, it will mesh with the driven gear 11. The driven gear 11 will then transmit the rotational motion to the deflecting wheel 15 through the rotating roller 10, causing it to rotate eccentrically and synchronously drive the connecting sleeve wheel 16 to pull the anti-blocking bucket 14. With the help of the elasticity of the spring rod 13, the anti-blocking bucket 14 is supported, realizing the up-and-down reciprocating motion of the anti-blocking bucket 14. This allows the anti-blocking bucket 14 to stir and crush the raw materials to prevent blockage when the materials fall.

[0040] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
