Abstract
Description
Technical Field
[0001] This invention relates to the field of circulating cooling technology for nursing products, specifically a cooling fluid circulation device for the production and processing of eye patches. Background Technology
[0002] Eye patches are a type of skincare product specifically designed for the eye area. They typically contain gold particles and various traditional Chinese medicine ingredients or other essences, which provide ample nutrition and moisture to the delicate skin around the eyes. The manufacturing process involves mixing a polymer matrix material with a solvent, heating and stirring until completely dissolved, then pouring the mixture into a mold or evenly coating it onto a release film using a casting machine to form a transparent film layer. This film is then cured by drying or cooling to create a transparent eye patch.
[0003] During the drying or cooling curing process, due to the need for assembly line operation, the temperature of the cooling device will slowly rise due to prolonged contact with the heated solvent. Failure to cool the cooling device in time may result in slow cooling and curing of the eye patches, affecting subsequent packaging processes. In addition, the solvent of the eye patches has a certain degree of adhesion, which may adhere to the surface of the cooling device during cooling. When cooling the solvent of the next batch of eye patches, it may enter the solvent of the eye patches, which may affect the shape of the eye patches or cause the solvent to overflow, affecting the quality of the eye patches.

Detailed Implementation
[0042] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0043] Example 1: As Figures 1-11 As shown, a cooling fluid circulation device for the production and processing of eye patches according to the present invention includes a cooling mold 470.
[0044] A cooling cover 472 is provided at the bottom of the cooling mold 470. The cooling cover 472 is used for heat exchange with the eye patch. The inner wall of the cooling cover 472 has flow channels for coolant circulation.
[0045] Both ends of the cooling cover 472 are connected through a circulating fluid pipe assembly 460. The circulating fluid pipe assembly 460 is connected to the flow channel, and the circulating fluid pipe assembly 460 allows the coolant to circulate into the flow channel inside the cooling mold 470 for cooling.
[0046] The cooling mold 470 has a dividing component at the bottom, and the cooling cover 472 has dividing components in the middle and on both sides of the lower surface. The dividing components are used to cut the box for storing eye patches into a preset width.
[0047] The solvent for the eye patch is a hydrogel material. The hydrogel material can solidify naturally at room temperature (20°C~25°C), but it can be accelerated by active cooling. The temperature is usually controlled between 10°C and 20°C to improve production efficiency. The cooling cover 472 can cooperate with the bottom-formed gold eye patch plastic mold. The cooling cover 472 is at a low temperature of 4°C. After the solvent of the eye patch is heated and mixed, the heating temperature is generally between 90°C and 95°C to ensure that the raw materials are fully dissolved and mixed evenly. When the cooling cover 472 comes into contact with the solvent of the eye patch, it can quickly exchange heat with the solvent of the eye patch, so that it can quickly reduce the temperature to below 20°C and solidify. The top of the solvent of the eye patch comes into contact with the cooling cover 472 first and solidifies, which can quickly set its shape and avoid liquid overflow.
[0048] The cooling seat 100 provides support, and the conveyor belt 200 transports the box containing the eye patches.
[0049] The circulating fluid pipe assembly 460 can cool the cooling cover 472. The circulating fluid pipe assembly 460 can circulate the coolant in the refrigeration box 600 on one side to the cooling mold 470. The refrigeration box 600 pre-cools the coolant to -20°C. At night, it uses off-peak electricity to make ice for cold storage (phase change material: Na2SO4·10H2O). During the day, it releases cold energy, reducing the overall energy consumption by 35%. The circulating fluid pipe assembly 460 injects coolant into the cooling cover 472 and the cooling mold 470. The cooling cover 472 can be immersed in the low-temperature coolant. At the same time, the coolant can flow into the flow channel inside the cooling cover 472 to ensure heat exchange efficiency. It can shorten the cooling cycle from 15 seconds in traditional water cooling to 4 seconds, improving cooling efficiency.
[0050] Specifically, the flow channel includes multiple sets of multi-level liquid holes 4721; the multi-level liquid holes 4721 are distributed along the inner wall of the cooling cover 472 for the flow of coolant;
[0051] The multiple sets of multi-level liquid holes 4721 can be made into multiple flow channels inside the cooling cover 472 by using 3D metal printing. The flow channels can be biomimetic tree-shaped microchannels with a diameter of 0.5-2mm. Compared with traditional straight flow channels, the heat dissipation area is increased by 200%.
[0052] It can also be a curved multi-stage liquid hole 4721, with a simpler processing technology and a diameter between 3mm and 5mm. The cooling cover 472 is cooled down quickly by the rapid flow of coolant.
[0053] The trumpet-shaped tube 4722 is connected to the inner wall of the multi-stage liquid hole 4721, and the coolant flows from the end with the larger opening to the end with the smaller opening of the trumpet-shaped tube 4722.
[0054] The multi-stage liquid orifice 4721 is equipped with a trumpet-shaped tube 4722, which can prevent coolant backflow during the coolant flow process.
[0055] Specifically, the inner wall of the cooling cover 472 is provided with a layer of porous graphene thermal conductive film, wherein the porous graphene thermal conductive film is 50μm thick and has a thermal conductivity of 1800W / m·K; and the surface is sprayed with a hydrophobic nano coating.
[0056] The porous graphene thermal conductive film accelerates heat conduction and ensures rapid cooling when the solvent in the next set of eye patches reaches the preset range and comes into contact with the cooling cover 472. It replaces the traditional copper heat sink, which has a thermal conductivity of about 401 W / (m·K) and is more effective. The self-cleaning function is achieved by spraying a hydrophobic nano-coating to avoid dust accumulation affecting heat dissipation.
[0057] Specifically, the cooling cover 472 is made of a high thermal conductivity metal material.
[0058] The cooling cover 472 is made of highly thermally conductive metals such as copper, aluminum, and silver. The thermal conductivity of silver is approximately 429 W / (m·K), and that of aluminum is approximately 237 W / (m·K). In this embodiment, a copper cooling cover 472 is used, which can save manufacturing costs while ensuring the thermal conductivity of the cooling cover 472.
[0059] Specifically, it also includes a partition 471, which divides the cooling mold 470 into two spaces, and the two spaces are connected by a notch reserved at the end of the partition 471.
[0060] The partition 471 divides the cooling mold 470 into two spaces, which guides the flow of coolant. The coolant flows from the space near the cooling cover 472 to the space above, and then flows out of the cooling mold 470, realizing the circulation of coolant and ensuring that the coolant can flow in an orderly manner, so as to achieve the goal of cooling the cooling mold 470 by circulating the coolant.
[0061] Specifically, a guide plate 475 is fixedly provided on the side of the partition 471 near the cooling cover 472. The guide plate 475 is a copper sheet and all guide plates 475 are inclined.
[0062] The two adjacent sets of guide plates 475 are arranged in a staggered manner.
[0063] The staggered arrangement of the guide plates 475 increases the distance the coolant can flow, allowing the coolant to fully exchange heat with the cooling cover 472, thereby achieving continuous and rapid cooling of the solvent in the eye patch.
[0064] Example 2: Basically the same as Example 1, such as... Figure 2 and Figure 4-11As shown, the difference is that the circulating fluid pipe assembly 460 includes a primary outlet pipe 462, a primary inlet pipe 464, a secondary outlet pipe 463, and a secondary inlet pipe 465, wherein a press pump 467 is provided in the middle of the primary inlet pipe 464 and the secondary inlet pipe 465;
[0065] The primary liquid outlet pipe 462 and the primary liquid inlet pipe 464 extend into the cooling mold 470 and are connected to the multi-stage liquid hole 4721 through the connecting pipe 474.
[0066] The secondary liquid outlet pipe 463 and the secondary liquid inlet pipe 465 are respectively connected to the two spaces separated by the partition plate 471.
[0067] The primary liquid outlet pipe 462 and the primary liquid inlet pipe 464 are connected to the multi-stage liquid hole 4721 through the connecting pipe 474. During the reciprocating pressing process of the press pump 467, the coolant is pumped from the refrigeration box 600 into the multi-stage liquid hole 4721. The cooling cover 472 heats up quickly when it comes into contact with the solvent of the eye patch. The internal space of the multi-stage liquid hole 4721 is smaller than the internal space of the cooling mold 470. The press pump 467 enables the coolant in the multi-stage liquid hole 4721 to circulate faster, ensuring that the coolant flows quickly and thus quickly exchanges heat with the cooling cover 472.
[0068] The secondary outlet pipe 463 and the secondary inlet pipe 465 are respectively connected to the two spaces of the cooling mold 470 separated by the partition plate 471. The coolant can enter the space below the cooling mold 470 from the secondary inlet pipe 465 and flow to the space above the cooling mold 470 and out from the secondary outlet pipe 463. The cooling mold 470 has a large amount of coolant, and the cooling cover 472 is continuously immersed in the coolant, which can continuously exchange heat and continuously cool the cooling cover 472 to ensure the cooling effect of the cooling cover 472 on the solvent of the eye patch.
[0069] Specifically, a reciprocating pressure plate 468 is provided on one side of the cooling mold 470, and the reciprocating pressure plate 468 is configured in conjunction with the press pump 467.
[0070] As the cooling mold 470 moves downward, it presses the pump 467 by the reciprocating pressure plate 468. When the pump 467 is pressed down once, the coolant inside the multi-stage liquid holes 4721 will circulate once during one press, ensuring the circulation efficiency of the coolant in the multi-stage liquid holes 4721.
[0071] Example 3: Basically the same as Example 1, such as... Figure 1-4 and Figure 6 As shown, the difference is that the top of the cooling mold 470 is connected to a connecting plate 435, and the top of the connecting plate 435 is provided with a mold control mechanism 300 for controlling the movement of the cooling mold 470.
[0072] The mold control mechanism 300 includes a mold support platform 400 and a mold drive component 430;
[0073] The mold drive component 430 is used for driving the reciprocating movement of the mold;
[0074] The mold support platform 400 includes a second platform 410, and the bottom of the second platform 410 is connected to the first platform 500 via a cylinder 420.
[0075] The mold drive component 430 includes multiple guide shafts 436, the lower end of which passes through the first platform 500 and the second platform 410 and is fixedly connected to the top of the connecting plate 435.
[0076] Multiple guide shafts 436 are connected into a whole by a synchronous connecting piece 432. A mounting bracket 431 is provided on the top of the second platform 410. An electric control push rod 433 is connected between the mounting bracket 431 and the synchronous connecting piece 432.
[0077] During cooling, the bottom of the second platform 410 is first controlled to shorten through the telescopic end of the cylinder 420, causing the second platform 410 to descend, so that the cooling mold 470 moves downward and approaches the solvent of the eye patch. When the telescopic end of the cylinder 420 is shortened to the preset position, the electric push rod 433 is then controlled to extend rapidly. The telescopic end of the electric push rod 433 pushes the synchronous connecting piece 432. The synchronous connecting piece 432 pushes the connecting plate 435 downward through multiple guide shafts 436. The connecting plate 435 adjusts the cooling mold 470 to move synchronously. At this time, the cooling cover 472 comes into contact with the solvent of the eye patch for cooling.
[0078] After the cylinder 420 extends to the preset position, the dividing blade 478 of the dividing assembly contacts the box containing the eye patches. The box containing the eye patches is conveyed to the bottom of the dividing blade 478 via a metal conveyor belt. The dividing blade 478 cuts the edge of the box containing the eye patches, splitting it in two. As the electrically controlled push rod 433 extends rapidly, the dividing blade 478 begins to cut the box containing the eye patches. If the dividing blade 478 encounters a hard obstacle during the cutting process, the spring 479 at the top of the dividing blade 478 will be compressed, preventing damage to the dividing blade 478.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
