A mixing device for producing facial mask liquid

Abstract

This utility model relates to the field of facial mask liquid production technology, specifically a mixing device for facial mask liquid production. It includes a hopper and an injection pipe. A stirring mechanism is installed inside the hopper, and a retaining element is installed at its upper part to initially retain the facial mask liquid entering from the injection pipe in a storage area. A pre-stirring rod is installed on the stirring mechanism to pre-mix a small amount of facial mask liquid in the storage area. As the amount of facial mask liquid injected into the storage area increases, the pre-mixed facial mask liquid overflows from the retaining element into the stirring area. This utility model, with its retaining element, pre-stirring rod, and storage area, allows for a smaller amount of facial mask liquid injected into the storage area. The pre-stirring rod can pre-stir to achieve high mixing effect and efficiency. When the facial mask liquid overflows from the storage area into the stirring area, the stirring mechanism can perform a secondary overall stirring of the pre-mixed facial mask liquid concentrated in the stirring area, further ensuring mixing uniformity. Furthermore, because the individual pre-mixing and overall stirring are continuous, the mixing efficiency is also improved.

Description

Technical Field

[0001] This utility model relates to the field of facial mask liquid production technology, specifically a mixing device for facial mask liquid production. Background Technology

[0002] Facial masks are a category of skincare products used to hydrate the skin and offer various functions such as moisturizing, nourishing, improving appearance, and deep cleansing. Facial masks typically consist of a mask sheet and a serum. The serum contains numerous ingredients, which need to be evenly dispersed during production.

[0003] Patent application number 201821508474.7 discloses a mixing device for producing a facial mask liquid for removing age spots. This device uses a stirring device and a rotating device operating together. The rotating device drives the mixing tank to rotate counterclockwise, while the stirring rod inside the stirring device rotates clockwise, resulting in a more uniform mixing of the facial mask liquid and improving its efficacy. However, because the amount of facial mask liquid added to the mixing tank at one time is relatively large, even the mixing device in the aforementioned patent has difficulty quickly dispersing the liquid, limiting the production efficiency of the facial mask liquid. Therefore, this paper proposes a mixing device for producing facial mask liquid. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a mixing device for producing facial mask liquid. By adding a retaining element and a pre-stirring rod, it ensures uniform mixing and improves mixing efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a mixing device for producing facial mask liquid, comprising a hopper and an injection pipe connected to and installed at the end of the hopper, wherein a stirring mechanism is installed inside the hopper and a retaining component is installed in the upper part of the hopper, so that the facial mask liquid entering from the injection pipe is initially retained in the storage area.

[0006] A pre-stirring rod is installed on the stirring mechanism and works synchronously with the stirring mechanism to pre-mix a small amount of facial mask liquid in the storage area. As the amount of facial mask liquid injected into the storage area increases, the pre-mixed facial mask liquid overflows from the interceptor to the stirring area.

[0007] The interceptor includes a connecting part that is fixed to the inside of the silo. The inner side of the connecting part is arched upward to form an inclined part, and an overflow port that is not completely closed is reserved at the center of the inclined part.

[0008] Preferably, the injection pipe has an injection port at the bottom near the storage area, and the end of the injection pipe extends into the stirring area through the connector and is equipped with a solenoid valve.

[0009] Preferably, an annular baffle is installed on the inner side of the inclined section near the overflow port to prevent the overflowing mask liquid from flowing along the inclined section and falling outside the stirring zone.

[0010] Preferably, the stirring mechanism includes a support shaft rotatably mounted at the center of the silo, and a geared motor mounted on the top of the silo to drive the support shaft to rotate. The bottom of the support shaft passes through the overflow port and is fixed with stirring blades.

[0011] Preferably, a deflector is provided between the pre-stirring rod and the support shaft to drive the pre-stirring rod to move up and down.

[0012] Preferably, the deflector includes a bushing A slidably mounted on the support shaft and fixed to the pre-stirring rod, and a limiting plate A fixed on the support shaft, wherein an electric actuator for driving the bushing A to move is mounted on the limiting plate A.

[0013] Preferably, the deflector includes a bushing B slidably mounted on the support shaft and fixed to the pre-stirring rod, and a limiting plate B fixed on the support shaft, with a tension spring sleeved between the limiting plate B and the bushing B.

[0014] This invention provides a mixing device for producing facial mask liquid, which has the following advantages compared with the prior art:

[0015] 1. It is equipped with a retaining element, a pre-stirring rod, and a liquid storage area. The amount of mask liquid injected into the liquid storage area is relatively small, and the pre-stirring rod can mix it in advance, resulting in high stirring effect and efficiency. When the mask liquid in the liquid storage area overflows into the stirring area, the stirring mechanism can perform a second overall stirring of the pre-mixed mask liquid concentrated in the stirring area to further ensure the uniformity of mixing. Moreover, since the individual pre-mixing and overall stirring are continuous, the mixing efficiency is also improved.

[0016] 2. An annular baffle is installed. When the mask liquid flowing out of the overflow port flows along the inner wall of the inclined part, it will be blocked by the annular baffle. Finally, it will drip from the bottom of the annular baffle to the near center of the mixing zone. Since the flow rate of the mask liquid in the center is fast, it can effectively disperse the newly fallen mask liquid and fully ensure the mixing effect of the mask liquid.

[0017] 3. An eccentric component is installed to achieve rotation and up-and-down movement of the pre-stirring rod, which can improve the pre-mixing effect of the mask liquid in the storage area. Attached Figure Description

[0028] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0029] Example 1

[0030] Directly injecting the facial mask liquid into the vessel and stirring it is inefficient due to the large volume of liquid. Relying solely on the stirring mechanism requires a long stirring time and results in uneven mixing. This is because adding too much at once leads to a high flow rate at the center of the vortex and a slower flow rate at the periphery, resulting in insufficient mixing. If smaller portions are stirred individually and thoroughly before the overall large-scale stirring, the mixing effect and efficiency can be significantly improved. Therefore, this embodiment provides a mixing device for facial mask liquid production, such as... Figures 1-6As shown, it includes a hopper 1 and a liquid injection pipe 2 connected to the end of the hopper 1. The liquid injection pipe 2 has a liquid injection port 3 at the bottom near the liquid storage area. The liquid injection port 3 can continuously replenish the liquid storage area in small amounts. The end of the liquid injection pipe 2 extends into the stirring area through the connecting part 51 and is equipped with a solenoid valve 4. When it is necessary to completely drain the liquid in the hopper 1, the solenoid valve 4 can be opened. Under the action of gravity, the residual liquid in the liquid storage area can enter the liquid injection pipe 2 through the liquid injection port 3 and be discharged into the stirring area. Finally, it can be discharged from the pipe at the bottom of the hopper 1. A stirring mechanism 6 is installed inside the silo 1, and a retaining element 5 is installed on its upper part. A liquid storage area is formed between the retaining element 5 and the inner wall of the silo 1. The mask liquid entering from the injection pipe 2 is initially retained in the liquid storage area. A pre-stirring rod 7 is installed on the stirring mechanism 6, which works synchronously with the stirring mechanism 6 to pre-mix the small amount of mask liquid in the liquid storage area. As the amount of mask liquid injected into the liquid storage area increases, the pre-mixed mask liquid overflows from the retaining element 5 into the stirring area. In the continuous mixing process of the mask liquid, it is first injected into the liquid storage area through the injection pipe 2. The amount of mask liquid in the liquid storage area is small, and the pre-stirring rod 7 can stir it evenly in advance. Due to the small amount of mask liquid, the stirring effect and efficiency are high. As the injection tube 2 continuously injects the liquid, the amount of mask liquid in the storage area gradually increases and overflows. The stirred mask liquid will then overflow into the stirring area. At this time, the stirring mechanism 6 can perform a second overall stirring of the premixed mask liquid concentrated in the stirring area to further ensure the uniformity of mixing. Moreover, since the individual premixing and overall stirring are continuous, the mixing efficiency is also improved.

[0031] The aforementioned retaining component 5 specifically includes a connecting part 51 fixed inside the hopper 1. This section is horizontally arranged to facilitate fixing to the inner wall of the hopper 1. The inner side of the connecting part 51 is arched upward to form an inclined part 52, which forms a liquid storage area with the inner wall of the hopper 1. An overflow port 53 that is not completely closed is reserved at the center of the inclined part 52. As the mask liquid in the liquid storage area is continuously injected, the excess mask liquid will flow out from the overflow port 53 into the stirring area.

[0032] During simulated production, technicians discovered that the mask liquid flowing out of the overflow port 53 would flow along the inner wall of the inclined part 53. This part of the mask liquid would flow to the lowest end of the inclined part 53 and then drip continuously into the mixing zone. However, the flow rate at the periphery was slower, and this part of the overflowing mask liquid could not be fully mixed into the existing mask liquid in the mixing zone.

[0033] Furthermore, a separate annular baffle 8 is installed on the inner side of the inclined section 52 near the overflow port 53 to prevent the overflowing mask liquid from flowing along the inclined section 52 and falling onto the outer edge of the mixing zone. At this time, the mask liquid flowing out of the overflow port 53 is blocked by the annular baffle 8 as it flows along the inner wall of the inclined section 53, and finally drips from the bottom of the annular baffle 8 to the near center of the mixing zone. Because the flow rate of the mask liquid at the center is fast, it can effectively disperse the newly fallen mask liquid, fully ensuring the mixing effect of the mask liquid.

[0034] The stirring mechanism 6 mentioned in this embodiment includes a support shaft 61 rotatably mounted at the center of the hopper 1, and a geared motor 63 mounted on the top of the hopper 1 to drive the support shaft 61 to rotate. The bottom of the support shaft 61 passes through the overflow port 53 and is fixed with a stirring blade 62. By starting the geared motor 63, the support shaft 61 is driven to rotate, and the stirring blade 62 fixed on the support shaft also rotates accordingly, thereby performing overall stirring of the mask liquid falling into the stirring zone. At the same time, the pre-stirring rod 7 also rotates accordingly.

[0035] To further improve the stirring effect of the facial mask liquid in the storage area, a deflector 9 is provided between the pre-stirring rod 7 and the support shaft 61 to drive the pre-stirring rod 7 to move up and down. The deflector 9 includes a bushing A 91 slidably mounted on the support shaft 61 and fixed to the pre-stirring rod 7, and a limiting plate A 93 fixed on the support shaft 61. An electric actuator 92 that drives the bushing A 91 to move is mounted on the limiting plate A 93. Specifically, as the support shaft 61 rotates, it drives the bushing A 91 to rotate, which in turn drives the pre-stirring rod 7 to rotate and premix the facial mask liquid in the storage area. At the same time, by controlling the electric actuator 92, the bushing A 91 and the pre-stirring rod 7 on it are driven to move up and down reciprocally, realizing the rotation and up and down movement of the pre-stirring rod 7, which can improve the premixing effect of the facial mask liquid in the storage area.

[0036] Example 2

[0037] Basically the same as in Example 1, see reference. Figure 7 The difference lies in the following: the biasing component 10 includes a bushing B 101 slidably mounted on the support shaft 61 and fixed to the pre-stirring rod 7, and a limiting plate B 103 fixed on the support shaft 61. A tension spring 102 is sleeved between the limiting plate B 103 and the bushing B 101. Compared with the biasing component 9, the use of the tension spring 102 cannot actively move the pre-stirring rod 7 up and down. It can only cause the pre-stirring rod 7 to vibrate through the contact action between the pre-stirring rod 7 and the mask liquid during stirring. In conjunction with the tension spring 102, the pre-stirring rod 7 can be offset up and down within a small range. In terms of premixing effect, the biasing component 10 in this embodiment is not as good as the biasing component 9 in embodiment 1, but the structure of the biasing component 10 is simpler and the cost is reduced.
