Abstract
Description
Technical Field
[0001] This utility model relates to the field of condom color matching technology, and in particular to a color matching mechanism for the production of colored polyurethane condoms. Background Technology
[0002] In the production of polyurethane condoms, the dyeing process is a crucial step that determines the product's appearance quality and market acceptance. Traditional dyeing methods typically involve mixing liquid dyes with polyurethane raw materials and then stirring to achieve a uniform color distribution. However, due to the high viscosity of polyurethane materials and the dispersibility of dyes, insufficient stirring can easily lead to uneven color distribution, affecting the product's consistency and aesthetics.
[0003] Currently, common dye mixing technologies in the industry mainly include mechanical stirring, magnetic stirring, and static mixing. Mechanical stirring typically uses low-speed impellers or spiral stirrers, relying on a motor to drive the stirring shaft to rotate, thus initially mixing the dye with the polyurethane material. Magnetic stirring uses a magnetic field to drive a stir bar to rotate within a sealed container, suitable for small-scale or high-precision mixing needs. Static mixers, through fixed mixing elements, cause the fluid to be divided and recombined multiple times during flow, thereby achieving uniform mixing.
[0004] However, the aforementioned mixing method still has significant shortcomings when applied to the production of colored polyurethane condoms. Especially in the absence of an efficient mixing system, the mixing of dye and polyurethane material is often insufficient, leading to inconsistent dyeing effects and problems such as color spots or uneven color depth on the product surface. This not only affects the appearance quality of the product but also increases the difficulty of quality control due to batch-to-batch color differences, thereby reducing production efficiency and market competitiveness. Therefore, a color matching mechanism for the production of colored polyurethane condoms is proposed to solve these problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a color matching mechanism for the production of colored polyurethane condoms, which aims to improve the problem that the dye cannot be fully and evenly mixed when there is a lack of an efficient stirring system in the prior art, resulting in inconsistent dyeing effects.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0015] As a further description of the above technical solution:
[0016] The piston sidewall is fixedly connected to a water inlet pipe and a drain pipe, and the piston bottom is fixedly connected to a fixing column.

[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, the rotating plate is driven by the first motor to rotate. The rotation of the rotating plate causes the rotating column to rotate inside the hollow column.

Detailed Implementation
[0033] 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.
[0034] Reference Figure 1 - Figure 3 An embodiment of this utility model provides a color matching mechanism for the production of colored polyurethane condoms, including a support 1, a material tank 2 fixedly connected to the inner wall of the support 1, a support plate 3 fixedly connected to the top of the material tank 2, a first motor 4 fixedly connected to the top of the support plate 3, the first motor 4 being used to drive a rotating plate 5 to rotate, thereby driving the stirring assembly to run, realizing the stirring and mixing of polyurethane raw materials and dyes in the material tank 2, improving the mixing uniformity, and avoiding uneven dyeing; the output end of the first motor 4 is fixedly connected to the rotating plate 5, and the bottom of the support plate 3 is provided with a stirring assembly;
[0035] The mixing assembly includes a hollow column 6, the top of which is fixedly connected to the bottom of the support plate 3. A sliding ring 7 is provided inside the hollow column 6, and a rotating column 28 is rotatably connected inside the sliding ring 7. The rotating column 28 rotates and moves up and down in conjunction with the limiting column 8 and the sliding ring 7. The rotating column 28 rotates under the drive of the rotating plate 5, and the limiting column 8 slides along the sliding ring 7, which ensures both rotational stability and up and down movement, so that the mixing blade 10 can be mixed at multiple angles within the effective mixing area. The rotating column 28 is slidably connected to the outer wall of the rotating plate 5, and the limiting column 8 is fixedly connected to the outer wall of the rotating column 28. The outer wall of the limiting column 8 is rotatably connected to the inside of the sliding ring 7. A drive shaft 9 is fixedly connected to the bottom of the rotating column 28, and the mixing blade 10 is fixedly connected to the outer wall of the drive shaft 9. The mixing blade 10 is used to mix the polyurethane raw material and dye in the material tank 2, so that the two are fully mixed, avoiding uneven dyeing caused by insufficient mixing, and improving color matching stability. The outer wall of the mixing blade 10 is rotatably connected to the inside of the material tank 2.
[0036] Reference Figure 1 , Figure 4 and Figure 5 A support column 11 is fixedly connected to the top of the bracket 1. A second connecting block 29 is fixedly connected to the top of the support column 11. An inlet pipe 12 is fixedly connected inside the second connecting block 29. A sliding valve 13 is slidably connected inside the second connecting block 29. A first connecting block 14 is fixedly connected to the side wall of the second connecting block 29. A threaded sleeve 15 is fixedly connected to the top of the first connecting block 14. A discharge pipe 22 is fixedly connected to the bottom of the first connecting block 14. A threaded rod 17 is threadedly connected inside the threaded sleeve 15. The threaded rod 17 cooperates with the threaded sleeve 15 for adjustment. The initial position of piston 20 is changed by rotating turntable 16 to move threaded rod 17 within threaded sleeve 15, thereby altering the sliding stroke of piston 20 and achieving precise adjustment of the amount of dye drawn in. This is a well-known threaded transmission structure, which will not be elaborated further here. One end of threaded rod 17 is fixedly connected to turntable 16, and the other end of threaded rod 17 is equipped with piston 20. The outer wall of piston 20 is slidably connected to the inside of first connecting block 14. The side wall of piston 20 is fixedly connected to water inlet pipe 18 and drain pipe 19. Water inlet pipe 18 is used to introduce liquid to drive piston 20. The stopper 20 slides in the reverse direction, thereby causing the fixed column 30 to move downward and contact the plug 24, allowing the dye to be discharged and achieving quantitative dye addition. The bottom of the piston 20 is fixedly connected to the fixed column 30. A connecting pipe 21 is opened inside the first connecting block 14. The outer wall of the fixed column 30 is slidably connected to the inside of the connecting pipe 21. A connecting plate 23 is fixedly connected inside the first connecting block 14. A connecting column 25 is slidably connected inside the connecting plate 23. One end of the connecting column 25 is fixedly connected to a limit ring 27. The top of the limit ring 27 is slidably connected to the bottom of the connecting plate 23. The connecting column 25 has a plug 24 fixedly connected to its top. The plug 24, in conjunction with the spring 26 and the connecting column 25, performs a closing and opening motion. When the fixed column 30 abuts, the plug 24 opens the connecting pipe 21. Under the action of the spring 26's rebound force, the connecting pipe 21 is closed, achieving the effect of controlling the discharge and cut-off of dye. The top of the plug 24 is slidably connected to one end of the connecting pipe 21. A spring 26 is provided on the outer wall of the connecting column 25. One end of the spring 26 is fixedly connected to the outer wall of the connecting column 25, and the other end of the spring 26 is fixedly connected to the top of the connecting plate 23.
[0037] Working principle: When the dye is stirred, the first motor 4 starts and drives the rotating plate 5 to rotate. The rotating plate 5 drives the rotating column 28 to rotate inside the hollow column 6. The limiting column 8 on the outer wall of the rotating column 28 slides along the sliding ring 7 to ensure that the rotating column 28 rotates stably and does not deviate. The transmission shaft 9 at the bottom of the rotating column 28 rotates accordingly, which in turn drives the stirring blade 10 to rotate at high speed inside the material tank 2, so as to fully stir and mix the polyurethane raw materials and dyes in the tank. The cooperation between the limiting column 8 and the sliding ring 7 restricts the axial displacement of the rotating column 28, retaining only the circumferential rotational freedom. At the same time, through the design of the sliding ring 7, the limiting column 8 can be driven to move up and down inside the hollow column 6, so that the stirring blade 10 always stays in the effective stirring area, avoiding uneven mixing due to shaking, and significantly improving the mixing uniformity of dye and raw materials.
[0038] When adding dye in a measured amount, liquid is discharged through drain pipe 19. Piston 20 slides within first connecting block 14, generating negative pressure. This negative pressure causes sliding valve 13 to slide within second connecting block 29, disengaging it from the inlet pipe 12. Dye is then drawn into the cavity of first connecting block 14 through inlet pipe 12. Subsequently, liquid is introduced through water inlet pipe 18, pushing piston 20 to slide in the opposite direction. The fixed post 30 at the bottom of piston 20 moves down along connecting pipe 21 and abuts against plug 24. Plug 24, under pressure, causes connecting post 25 to slide along connecting disc 23, compressing spring 26. Plug 24 separates from connecting pipe 21, forming a channel, and dye in the cavity is discharged through discharge pipe 22. After addition is complete, piston 20 returns to its original position, and the rebound force of spring 26 pushes connecting post 25 upward, causing plug 24 to re-close connecting pipe 21. By controlling the sliding stroke of piston 20, the amount of dye drawn in can be precisely controlled, achieving quantitative addition and ensuring consistent addition each time.
[0039] 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.
