Description

Technical Field

[0001] The invention relates to the technical field of hot compress patch preparation, and in particular to equipment for preparing an external nose and eye compress patch containing a hydrophilic gel and a hot compress patch production method. Background Art

[0002] External nose and eye patches are products that provide targeted care for the nose and eyes through physical action or drug penetration. Among them, hydrophilic gel, as the core component, can provide continuous hydration and moisturizing effects for the skin around the nose and eyes due to its excellent hydrophilic properties, thereby enhancing the comfort and care efficacy of the patch. In the preparation process of external nose and eye patches containing hydrophilic gel, the mixing process is a key step to ensure product quality. At present, the industry generally uses mixers for mixing, and the raw materials are fully mixed in the mixing tank through the mechanical movement of the stirring paddle.

[0003] The existing publication number CN115228358A discloses a hydraulic rotary stone grabber, which includes a workbench, a rotary table fixedly connected to the top of the workbench, and a rotary groove is opened on the top surface of the rotary table, and a rotary barrel assembly is arranged inside the rotary groove; a concave support frame is fixedly connected between the top of the two side edges of the top surface of the workbench, and two parallel vertical support plates are fixedly connected to the top of the inner wall of the concave support frame, a sleeve is detachably connected between the vertical support plate and the concave support frame through a connecting piece, and a stirring and mixing mechanism is arranged above the sleeve, and the rotary barrel assembly specifically includes: a rotary seat rotatably connected to the inside of the rotary groove, although the above technical scheme can remove all the mixed raw materials without shutting down the mixing equipment, and then send the unmixed raw materials up immediately to complete the continuous mixing of the raw materials, which has the advantage of improving the mixing efficiency.

[0004] However, in the mixing process, in order to adjust the fluidity of the hydrophilic gel, promote the dissolution of ingredients (such as high molecular weight polymers, thickeners, moisturizers, etc.), and ensure that the raw materials in the formula are fully integrated, heating means are usually required. In the prior art, the heating elements are mostly concentrated at the bottom, one side or the periphery of the mixing tank, resulting in uneven temperature distribution inside the equipment, which is specifically manifested as: the temperature of the area close to the heating source rises sharply, and the water evaporates rapidly; while the temperature of the area far away from the heating source rises slowly, and the evaporation of water is also delayed. This uneven temperature distribution will directly affect the performance of the hydrophilic gel. Since the adhesion of the hydrophilic gel hot compress mainly depends on the water content of the gel, uneven water volatilization will cause the water content of the gel in some areas to be too low, thereby significantly reducing the adhesion of the area, making the patch easy to fall off during use. In addition, areas with excessive water volatilization will also cause the thermal conductivity of the gel to decrease, affecting the performance of the hot compress in terms of heat generation and thermal conductivity, making it unable to fully exert the effect of warm care. Therefore, a new type of external nose and eye patch preparation equipment containing hydrophilic gel and a hot compress production method are needed to solve the above problems.

[0042] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0043] Reference Figure 1-Figure 4The present invention provides a preparation device for an external nose and eye patch containing a hydrophilic gel, comprising a tank 1 and a stirring rod 2, wherein the stirring rod 2 is provided with a plurality of injection members 5 for injecting steam, wherein the plurality of injection members 5 are arranged along the axial direction of the stirring rod 2, specifically, the injection member 5 comprises a shell 51, a straight spray pipe 52 fixed in the shell 51, and a sleeve 53 movably sleeved outside the straight spray pipe 52, wherein a flexible sleeve 54 is fixed to the inner edge of one end of the sleeve 53 away from the stirring rod 2, and the other end of the flexible sleeve 54 is fixed to the outer edge of the air outlet end of the straight spray pipe 52, wherein the end of the straight spray pipe 52 close to the stirring rod 2 is the air inlet end, and the end of the straight spray pipe 52 away from the stirring rod 2 is the air outlet end, wherein the straight spray pipe 52 is longer than the sleeve 53, and the length difference enables the sleeve 53 to be telescopic outside the straight spray pipe 52, thereby changing the steam injection state, and the inner diameter of the sleeve 53 is larger than the outer diameter of the straight spray pipe 52, so that the sleeve 53 can slide and rotate along the axial direction of the straight spray pipe 52, thereby realizing multi-state steam injection.

[0044] Reference Figure 8 The flexible sleeve 54 has three states. In the first state, the sleeve 53 is retracted into the shell 51, and the flexible sleeve 54 is conically sleeved on the outside of the direct injection pipe 52. At this time, when the steam can be directly ejected through the direct injection pipe 52, this injection state is relatively concentrated and can be used for directional steam supply in the initial mixing stage of the raw materials. In addition, a plurality of flexible strips 541 are evenly distributed on the outside of the flexible sleeve 54. In the second state, the sleeve 53 extends outward along the axial direction of the shell 51, and the flexible sleeve 54 is turned over in a trumpet shape and is located outside the outlet end of the direct injection pipe 52. At this time, the injection range of the steam is increased, and it can be diffused in a larger area of ​​the raw materials, which is helpful to quickly and evenly enhance the steam. The temperature and humidity of the raw materials meet the needs of rapid mixing. In the third state, the sleeve 53 rotates along the circumferential direction of the shell 51, and the flexible strip 541 twists with the flexible sleeve 54 and is spirally distributed on the inner side of the flipped flexible sleeve 54. At this time, the steam presents a spiral injection trajectory, which further accelerates the speed of steam injection. Through the extension and rotation of the sleeve 53, combined with the deformation of the flexible sleeve 54 and the flexible strip 541, a variety of steam injection states can be achieved, namely concentrated injection, diffuse injection and spiral injection, to adapt to different mixing stages and raw material characteristics, and meet different needs for steam injection in the process of preparing external nasal and eye patches containing hydrophilic gel.

[0045] At the same time, the setting of the flexible sleeve 54 and the flexible strip 541 in the injection member 5, combined with the multi-directional movement of the sleeve 53, further enhances the flexibility and uniformity of the steam injection, ensuring that the material can be quickly and evenly heated and humidified during the mixing process to meet the needs of rapid mixing. In addition, the synergistic effect of the rotation of the stirring rod 2 and the steam injection further promotes the dissolution and fusion of the components in the material, thereby improving the preparation quality and efficiency of the hydrophilic gel.

[0046] During the mixing process, the injection member 5 is mainly used to inject steam to provide heat, replacing the traditional centralized heating element. By evenly injecting steam into the raw materials, the problem of uneven temperature distribution caused by the fixed position of the heating source in the traditional heating method is avoided, ensuring that the raw materials can be evenly heated at all positions, thereby ensuring the stable performance of the hydrophilic gel.

[0047] Reference Figure 2 and Figure 5-Figure 6 A channel 3 is provided in the stirring rod 2, and an interface 4 corresponding to the shell 51 is provided on the stirring rod 2. The shell 51 and the interface 4 are connected by threads. A gas delivery component 6 for gas supply is provided on the tank 1. The gas delivery component 6 includes a steam generator 61, a pipeline 62 for connecting the steam generator 61 and the channel 3, and a pressure sensor 63 and a regulating valve 64 arranged on the pipeline 62. A controller is also provided on the tank 1. The controller is electrically connected to the regulating valve 64. During the mixing process, different injection states have different requirements for steam pressure. The controller controls the regulating valve 64 to set the pressure parameters required under different injection states.

[0048] Specifically, refer to Figure 5 A conduction pipe 31 is inserted through the channel 3, one end of the pipe 62 is connected to the steam generator 61, and the other end of the pipe 62 is connected to the conduction pipe 31. The conduction pipe 31 is fixed to the tank 1 through a bracket 32. The conduction pipe 31 is rotatably connected to the stirring rod 2 through a bearing. When the stirring rod 2 rotates, the conduction pipe 31 can be fixed by the bracket 32.

[0049] It should be noted that, refer to Figure 3 and Fig.10A control member 8 is provided in the shell 51. The control member 8 includes a track 81 opened in the shell 51. The track 81 includes a straight section 811 and a bent section 812. The straight section 811 and the bent section 812 are integrally connected. A slider 82 is slidably connected in the track 81. The end of the slider 82 away from the shell 51 is telescopically arranged on the sleeve 53. The sleeve 53 is also provided with a spring 83. The two ends of the spring 83 are respectively abutted on the sleeve 53 and the shell 51. When the position of the sleeve 53 needs to be changed to switch the state of the flexible kit 54, the steam pressure in the channel 3 is changed. The steam pressure increases so that the driving force pushes the sleeve 53 to move outward along the axial direction of the shell 51. At this time, the slider 82 is in the straight position. The flexible sleeve 54 enters the second state, i.e., it is flipped and trumpet-shaped outside the outlet end of the straight injection pipe 52, thereby expanding the steam injection range and continuously increasing the steam pressure. When the slider 82 slides into the bending section 812, the slider 82 causes the sleeve 53 to produce a circular rotational motion during the sliding process. As the sleeve 53 rotates, the flexible strip 541 originally located on the outside of the flexible sleeve 54 gradually spirally distributes on the inside of the flipped flexible sleeve 54 as the flexible sleeve 54 twists, thereby causing the flexible sleeve 54 to enter the third state. After reducing the steam pressure, the sleeve 53 is retracted into the shell 51 under the resetting action of the spring 1 83, and the flexible sleeve 54 presents the first state.

[0050] Among them, a chamber 531 for limiting and inserting the slider 82 is opened on the sleeve 53, and a spring 532 is connected between the slider 82 and the chamber 531. The function of the spring 532 is to facilitate the storage of the slider 82 into the chamber 531, thereby facilitating the installation of the sleeve 53.

[0051] Further, see Figure 6 An impeller 55 is provided at one end of the shell 51 close to the stirring rod 2, and the straight injection pipe 52 is fixedly connected to the shell 51 through a frame 56. The air inlet end of the straight injection pipe 52 is located on the side of the impeller 55 away from the stirring rod 2. Through the acceleration and guidance of the steam by the impeller 55, the steam entering the straight injection pipe 52 has higher kinetic energy and a more stable flow rate.

[0052] Among them, refer to Figure 7 A plurality of grooves 57 are formed on the inner wall of one end of the sleeve 53 away from the flexible sleeve 54, and a convex strip 58 matching the groove 57 is fixed to the outside of the straight nozzle 52. The cooperation between the convex strip 58 and the groove 57 guides the axial expansion and contraction of the sleeve 53, while reducing the friction between the sleeve 53 and the straight nozzle 52. The length of the convex strip 58 is slightly shorter than the length of the straight section 811. When the slider 82 slides to the junction of the straight section 811 and the bent section 812, the groove 57 is separated from the convex strip 58, which facilitates the rotation of the sleeve 53.

[0053] Reference Figure 7A cover shell 59 is fixed to the end of the sleeve 53 away from the stirring rod 2. The cover shell 59 is trumpet-shaped. The inner diameter of the small-mouth end of the cover shell 59 is slightly larger than the maximum outer diameter of the flexible sleeve 54 in the first state, so that when the flexible sleeve 54 is in the first state, it can be smoothly placed inside the cover shell 59. When the flexible sleeve 54 is in the second state, the inner diameter of the large-mouth end of the cover shell 59 will be larger than the maximum outer diameter of the flexible sleeve 54 in this state, so as to accommodate and guide the steam diffused from the flexible sleeve 54, thereby further expanding the diffusion range of the steam.

[0054] Reference Figure 3 and Figure 11-Figure 12 The direct injection pipe 52 is provided with an inlet 521, and an inlet pipe 522 is connected through the inlet 521. The sleeve 53 is provided with a gas port 533, and the gas port 533 can discharge excess gas through the inlet 521 and the inlet pipe 522 into the direct injection pipe 52 for ejection.

[0055] Reference Fig.13 The tank 1 is also provided with a driving member 7 for controlling the rotation of the stirring rod 2. The driving member 7 includes a motor 71 fixedly arranged on the tank 1, a transmission shaft 72 fixedly connected to the output end of the motor 71, a driving gear 73 fixed on the transmission shaft 72, and a driven gear 74 meshing with the driving gear 73. The driven gear 74 is fixed on the stirring rod 2. The controller is electrically connected to the motor 71. When the motor 71 is started, the output shaft of the motor 71 starts to rotate, driving the transmission shaft 72 fixedly connected thereto to rotate synchronously. Since the driving gear 73 is fixed on the transmission shaft 72, the driving gear 73 will also rotate with the transmission shaft 72. The driving gear 73 and the driven gear 74 are meshed with each other, so the stirring rod 2 will rotate with the rotation of the driven gear 74. During the rotation of the stirring rod 2, the injection member 5 arranged on the stirring rod 2 will also rotate accordingly, thereby promoting the dissolution and fusion of the components in the raw materials.

[0056] Working principle of a device for preparing external nose and eye patch containing hydrophilic gel:

[0057] First, the hydrophilic gel and other weighed raw materials are put into the tank 1, and then the motor 71 is started to drive the transmission shaft 72 to rotate, and the driving gear 73 rotates accordingly. The driving gear 73 and the driven gear 74 fixed on the stirring rod 2 are meshed with each other, thereby driving the stirring rod 2 to rotate, and the multiple groups of injection members 5 arranged along the axial direction of the stirring rod 2 rotate with the stirring rod 2;

[0058] At the same time, the steam generator 61 is started, the steam generator 61 generates steam and transports it to the channel 3 in the stirring rod 2 through the pipe 62. Then the steam enters the shell 51 through the channel 3 and the interface 4, and is ejected through the direct injection pipe 52. The pressure sensor 63 on the pipe 62 monitors the steam pressure in real time and feeds the data back to the controller. The controller controls the regulating valve 64 to accurately adjust the steam pressure according to the steam injection state required in different mixing stages. The transfer pipe 31 is inserted into the channel 3, one end of which is connected to the pipe 62, and the other end is fixed to the tank 1 through the bracket 32, and is rotatably connected to the stirring rod 2 through the bearing to ensure that the steam can be continuously and stably supplied when the stirring rod 2 rotates.

[0059] In the initial state, the steam pressure in the channel 3 is low, and the spring 83 shrinks the sleeve 53 into the shell 51. At this time, the flexible sleeve 54 is conically sleeved on the outside of the direct injection pipe 52, and the steam is directly ejected from the outlet end of the direct injection pipe 52 to form a concentrated injection. When it is necessary to expand the steam injection range, the controller controls the regulating valve 64 to increase the steam pressure in the channel 3. The driving force generated by the steam pressure pushes the sleeve 53 to move outward along the axial direction of the shell 51, and the slider 82 slides in the straight section 811. As the sleeve 53 is extended, the flexible sleeve 54 turns over and is located at the outlet end of the direct injection pipe 52 in a trumpet shape. The steam spray range increases, and the steam pressure continues to increase. The slider 82 slides into the bending section 812. During the sliding process, the slider 82 causes the sleeve 53 to rotate in a circular direction. The flexible strip 541 originally located on the outside of the flexible sleeve 54 twists with the flexible sleeve 54 and is spirally distributed on the inside of the flipped flexible sleeve 54, so that the steam presents a spiral spray trajectory. When the mixing process is completed or it is necessary to switch back to the centralized spray state, the steam pressure is reduced, and the reset action of the spring 83 causes the sleeve 53 to shrink into the shell 51, and the flexible sleeve 54 returns to the first state.

[0060] The present invention also provides a method for producing an external nose and eye hot compress containing a hydrophilic gel, comprising the following steps:

[0061] S1: Raw material preparation: according to the requirements of the hot compress formula, weigh the hydrophilic gel, thermal agent, moisturizer, and cross-linking agent raw materials, and put the weighed raw materials into tank 1;

[0062] S2: Mixing and heating: Start the steam generator 61 and control the stirring rod 2 to rotate, and inject hot steam into the tank 1 through the injection member 5, so that the raw materials are evenly heated and fully mixed during the stirring process;

[0063] S3: Molding: The mixed raw materials are conveyed into the mold, and the upper and lower molds of the mold are closed under the action of hydraulic or pneumatic devices. The raw materials are evenly distributed in the molding cavity under the pressure in the mold. After the patch is formed, the upper and lower molds are opened, and the demolded patch is conveyed to the cutting station through a conveyor belt;

[0064] S4: Cutting and packaging: The hot compress patch is cut according to the preset shape and size at the cutting station. The cut patches enter the packaging station. The automatic packaging machine puts the patches into sealed packaging bags and vacuums them. Then, the relevant information is printed on the packaging to complete the production of the hot compress patch.
