Description

Technical Field

[0001] The invention relates to an antibacterial medical dressing production device and a process thereof. Background Art

[0002] Liquid dressings are a type of medical product that is primarily used to cover and protect skin wounds. Unlike traditional dressings (such as gauze, bandages, etc.), liquid dressings are usually in liquid form and can form a protective film on the skin surface to reduce the risk of infection and promote wound healing. The main ingredients of liquid dressings include polyvinyl alcohol, acrylate copolymers, water, etc. During the production process of liquid dressings, affected by factors such as temperature and storage time, the more viscous liquid dressings sometimes precipitate or even clump.

[0003] The existing liquid dressing production equipment includes a barrel, which is mainly used to store various liquid materials. When the dressing needs to be produced, the liquid material in the barrel is transported to the production and processing equipment through a liquid supply pipeline. The conventional barrel is just a container. Some liquid materials have high viscosity and poor fluidity. After being stored for a long time, they are easy to precipitate or even agglomerate, resulting in worse fluidity. Therefore, additional heating and stirring are required before the material can be discharged. In this process, the raw materials are easily exposed to the outside world and contaminated, and manual participation is required, which reduces the production efficiency. Secondly, the main function of current liquid dressings is to establish a barrier to protect the wound site from bacterial infection, but the sterilization effect is low or not obvious. Therefore, there is a need for an antibacterial liquid dressing that can both establish a barrier and sterilize the wound. Summary of the invention

[0004] The object of the present invention is to provide an antibacterial medical dressing production device and process thereof to solve the problems raised in the above background technology.

[0009] A resistance-increasing sliding rod is arranged on one side of the bottom of the stop block of the discharge mechanism, and the resistance-increasing sliding rod passes through a pipe sleeve arranged on the liquid-blocking top plate of the component mounting structure. Sand rolling is adopted on the outer wall of the resistance-increasing sliding rod and the inner wall of the pipe sleeve to increase the friction between the two.

[0010] A production process for an antibacterial medical dressing comprises the following steps: S1: Glycosides, glycerol, acrylate and purified water are mixed in a ratio of 1:1:20 by mass, and then stirred at 60°C-65°C for 3 hours using a shear emulsifier to obtain solution A; S2: According to the mass ratio of antimicrobial agent, iodine solution and solution A of 1:0.5:20, firstly, all the antimicrobial agent is added into solution A, and stirred at 60°C-65°C for 1 hour by a shear emulsifier, and then the iodine solution is added in batches and mixed for 1 hour to obtain solution B; S3: Transfer solution B to a mixing tank, add the moisturizer into solution B in batches according to the ratio of moisturizer to solution B of 0.5:20 by mass to obtain solution C, and stir with a medium-sized agitator at 60°C-65°C and 200 rpm for 1 hour to obtain the antibacterial medical dressing solution.

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0016] See also Figure 1-4 , An antibacterial medical dressing production device comprises a material tank 1, a component mounting structure 2 is arranged in the material tank 1, and a mechanical transmission mechanism 3 and a material discharge mechanism 4 are arranged on the component mounting structure 2; The mechanical transmission mechanism 3 includes a driving motor 31, a threaded shaft 32 and an arm frame 33. The driving motor 31 is installed at the bottom of the chamber 5 of the component mounting structure 2, and its output shaft is connected to the threaded shaft 32. The arm frame 33 is installed on the threaded shaft 32 through the threaded sleeve 6 thereon. The arms 7 on the sides of the arm frame 33 pass through the arm slide 8 provided on the chamber 5 respectively, and are slidably installed on the discharge mechanism 4 through the sliding sleeve 9. The discharge mechanism 4 includes a stop block 41 and a support rod 42 fixed at the bottom of the stop block 41. The stop block 41 is arranged above the liquid drop port 11 of the liquid blocking top plate 10 of the component mounting structure 3. The sliding sleeve 9 at the end of the arm 7 of the arm frame 33 is slidably installed on the support rod 42; When it is necessary to discharge the material, the driving motor 31 is started to drive the threaded shaft 32 to rotate. At this time, the threaded sleeve 6 drives the support arm frame 33 to rise, and the support arms 7 on the sides of the support arm frame 33 slide upward along the arm slide groove 8, and the sliding sleeve 9 at its end slides upward along the support rod 42 until the sliding sleeve 9 lifts up the liquid blocking top plate 10. At this time, the liquid drop port 11 is opened, and the material can be discharged; It also includes a stirring piece 12, a threaded shaft 32 passes through a bearing sleeve fixed on the liquid retaining top plate 10 of the component mounting structure 2, and the hexagonal shaft 13 at the top thereof is matched and installed with the hexagonal groove at the bottom of the stirring piece 12. When the support arm 33 rises, the rotating threaded shaft 32 drives the stirring piece 12 to rotate through the hexagonal shaft 13 at the top thereof, thereby stirring the feed liquid. Therefore, this structure can stir the feed liquid before discharging to break the precipitation or agglomeration. When the liquid retaining top plate 10 is lifted up and the liquid outlet 11 is opened, the stirring piece 12 stops rotating, and the feed liquid can be discharged smoothly.

[0017] A sealing gasket 14 is arranged along the circumferential side of the bottom of the stop block 41. When the driving motor 31 drives the threaded shaft 32 to rotate in the reverse direction, the threaded sleeve 6 drives the support arm 33 to descend, and the sliding sleeve 9 slides down along the support rod 42. At this time, the stop block 41 falls due to its own gravity until the stop block 41 blocks the liquid outlet 11. At this time, the discharge stops, and the sealing gasket 14 can improve the sealing performance of the liquid outlet 11.

[0018] A support block 15 is provided on the upper portion of the support rod 42 , so that the sliding sleeve 9 can lift the stop block 41 to a certain height through the support block 15 , so that the liquid outlet 11 is opened to discharge the material.

[0019] It also includes a heating sleeve 17 installed on the outside of the material tank 1 through an annular bearing sleeve 16, a cover plate 18 is installed on the top of the heating sleeve 17, and the cover plate 18 is matched and installed in the hexagonal groove on the top of the stirring member 12 through a hexagonal support shaft 19 fixed at the bottom thereof. The rotating stirring member 12 can be linked to the heating sleeve 17 through the cover plate 18, and heat is heated while stirring, which can improve the stirring efficiency and make the fluidity of the liquid better; In addition, the heating jacket 17 is arranged on the outside of the material tank 1 instead of the inside, mainly because the material liquid may contain heat-sensitive materials, which require continuous, uniform and gentle heating and cannot be quickly and locally heated, which may easily destroy the effective ingredients of the materials. Example

[0020] See also Figure 5-6 A resistance-increasing slide bar 20 is arranged on one side of the bottom of the stop block 41 of the discharge mechanism 4. The resistance-increasing slide bar 20 passes through the pipe sleeve 21 arranged on the liquid-blocking top plate 10 of the component mounting structure 2. The design of this structure is mainly that when the stop block 41 falls under its own gravity, the resistance-increasing slide bar 20 is acted upon by the stop block 41 and slides along the pipe sleeve 21. The outer wall of the resistance-increasing slide bar 20 and the inner wall of the pipe sleeve 21 are both equipped with rolling sand to increase the friction between the two, which can extend the falling time of the stop block 41 (for example, without the resistance-increasing slide bar 20, the stop block 41 takes 2 minutes to fall, while with or without the resistance-increasing slide bar 20, the stop block 41 takes 3 minutes to fall), thereby making up for the insufficient discharge amount and discharging more liquid.
