Description

Technical Field

[0001] The utility model relates to the technical field of sunscreen product manufacturing, in particular to a foaming device. Background Art

[0002] At present, for some sunscreen products, it is necessary to fill the products with foam made of relatively viscous paste. However, the existing foaming devices have unstable foaming processes, and there may be situations of excessive or insufficient foaming. If there is excessive foaming, it is necessary to wait for the foam to disappear by standing; if there is insufficient foaming, it is necessary to rework to increase the foam. This not only affects the production efficiency and delivery time, but also since the sunscreen product is an aqueous agent, the risk of microbial contamination will increase during the process of defoaming or increasing the foam, affecting the product quality. Summary of the Utility Model

[0003] In order to solve the above technical problems, the utility model provides a foaming device, which ensures the stability of foaming, avoids the need for defoaming or increasing the foam, ensures the production efficiency of the product, thus ensuring the delivery time, avoids product contamination, and ensures the product quality.

[0004] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0005] A foaming device includes a pump, a stack filter, a first pipeline, and a material tank for containing materials. The liquid inlet of the pump is communicated with the material tank, the liquid outlet of the pump is communicated with the inlet of the stack filter through a feed pipe, an air inlet pipe is arranged on the feed pipe, and the other end of the air inlet pipe is used for connecting to an air source. The outlet of the stack filter is communicated with the first pipeline through a second pipeline, and the inner diameter of the second pipeline is larger than that of the first pipeline.

[0006] Preferably, a filter screen is arranged on the feed pipe between the pump and the air inlet pipe, and the precision of the filter screen is higher than that of the stack filter.

[0007] Preferably, the filtering precision of the filter screen is 0.15 - 0.25 μm, and the precision of the stack filter is 50 - 70 meshes.

[0008] Preferably, the diameter of the first pipeline is d, and the diameter of the second pipeline is D, where D = (8 - 12)d.

[0009] Preferably, the diameter of the first pipeline is 0.4 - 0.6 cm, and the diameter of the second pipeline is 4.5 - 5.5 cm.

[0010] Preferably, the first pipeline and the second pipeline are connected through a reducing joint.

[0011] Preferably, the pump is a piston pump.

[0012] Preferably, a pressure valve is provided on the intake pipe.

[0013] Preferably, it includes a controller, and both the pressure valve and the pump are electrically connected to the controller.

[0014] Preferably, a three-way valve is provided on the feed pipe, and the intake pipe is connected to the three-way valve.

[0015] Compared with the prior art, a foaming device according to an embodiment of the present invention has the beneficial effects that: the liquid outlet of the pump is communicated with the feed inlet of the stack filter through the feed pipe, an intake pipe is provided on the feed pipe, and the other end of the intake pipe is used to connect to a gas source. When foaming, the pump pumps the viscous paste in the material tank into the stack filter through the feed pipe, and at the same time, compressed air also enters the stack filter through the intake pipe. The material and the air are mixed in the stack filter, thereby generating bubbles. Thus, by only controlling the pumping speed of the pump and the pressure of the introduced compressed air, the stability of foaming can be achieved, avoiding the situation of excessive foaming that requires defoaming and insufficient foaming that requires additional foaming. This not only ensures the production efficiency and thus guarantees the delivery date, but also avoids the pollution caused by excessive exposure of the product.

[0016] In addition, by connecting the outlet of the stack filter to the first pipe through the second pipe, and the inner diameter of the second pipe is larger than that of the first pipe, the pressure in the first pipe can be increased by reducing the outlet, causing the materials to impact each other, thereby generating secondary foaming and further improving the product quality.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0020] In the description of the present application, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be a communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0021] The following will further describe in detail the specific implementation manners of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model but are not intended to limit the scope of the present utility model.

[0022] As Figure 1 shown, a foaming device according to a preferred embodiment of the present utility model includes a pump 1, a stack filter 2, a first pipe 3, and a material tank 4 for containing materials. The liquid inlet of the pump 1 is connected to the material tank 4 through a pipe, that is, the free end of the pipe extends into the material tank 4. The liquid outlet of the pump 1 is connected to the inlet of the stack filter 2 through a feed pipe 5. An air inlet pipe 6 is provided on the feed pipe 5, and the other end of the air inlet pipe 6 is used to connect to a gas source. The gas source is compressed air, and its pressure can be directly controlled. The outlet of the stack filter 2 is connected to the first pipe 3 through a second pipe 7, and the inner diameter of the second pipe 7 is larger than the inner diameter of the first pipe 3. The air inlet pipe 6 and the feed pipe 5 can be directly connected by a three-way valve 10. Specifically, a three-way valve 10 is provided on the feed pipe 5, and the air inlet pipe 6 is connected to the three-way valve 10. That is, the air inlet pipe 6 is respectively connected to two interfaces of the three-way valve 10, and the air inlet pipe 6 is connected to another interface of the three-way valve 10.

[0023] For the foaming device based on the above technical features, the liquid outlet of the pump 1 is connected to the inlet of the stack filter 2 through the feed pipe 5. An air inlet pipe 6 is provided on the feed pipe 5, and the other end of the air inlet pipe 6 is used to connect to a gas source. During foaming, the pump 1 pumps the viscous paste in the material tank 4 into the stack filter 2 through the feed pipe 5. At the same time, compressed air also enters the stack filter 2 through the air inlet pipe 6. The material and air are mixed in the stack filter 2, thereby generating bubbles. Therefore, by only controlling the pumping speed of the pump 1 and the pressure of the introduced compressed air, the stability of foaming can be achieved, avoiding the situation of excessive foaming that requires defoaming and insufficient foaming that requires additional foaming. This not only ensures the production efficiency and thus the delivery date but also avoids product contamination caused by defoaming or additional foaming.

[0024] In addition, the outlet of the laminated filter 2 is connected to the first pipeline 3 through the second pipeline 7, and the inner diameter of the second pipeline 7 is larger than that of the first pipeline 3. Thus, the pressure in the first pipeline 3 can be increased by narrowing the outlet, causing the materials to impact each other, thereby generating secondary bubbles and further improving the product quality.

[0025] In this embodiment, a filter screen 8 is provided on the feed pipe 5 between the pump 1 and the air inlet pipe 6, and the precision of the filter screen 8 is greater than that of the laminated filter 2. In this application, the laminated filter 2 is used for the first foaming, and the filter screen 8 is used for filtering materials. Therefore, the precision of the filter screen 8 needs to be set greater than that of the laminated filter 2 to ensure the quality and smooth progress of foaming.

[0026] Specifically, the filtration precision of the filter screen 8 is 0.15 - 0.25 μm, such as 0.16 μm, 0.17 μm, 0.18 μm, 0.19 μm, 0.2 μm, 0.21 μm, 0.22 μm, 0.23 μm, 0.24 μm, etc., or any value or range between any two of the above values, preferably 0.2 μm. The precision of the laminated filter 2 is 50 - 70 meshes, preferably 60 meshes.

[0027] In this embodiment, the diameter of the first pipeline 3 is d, and the diameter of the second pipeline 7 is D, where D = (8 - 12)d, such as D = 9d, D = 10d, D = 11d. When specifically setting, the inner diameter of the first pipeline 3 can be 0.4 - 0.6 cm, preferably 0.5 cm; the inner diameter of the second pipeline 7 is 4.5 - 5.5 cm, preferably 1.5 inches. When connecting, the first pipeline 3 and the second pipeline 7 are connected through a reducing joint 9, which is convenient for connecting the first pipeline 3 and the second pipeline 7. Or directly set a flange at the end of the second pipeline 7, and the first pipeline 3 is connected to the flange.

[0028] In this embodiment, the pump 1 is preferably a plunger pump, which is convenient for controlling the flow rate of the material. The air source connected to the air inlet pipe 6 can directly control the pressure of the air flow. However, to further ensure the stability of foaming, a pressure valve can be provided on the air inlet pipe 6 to detect the pressure of the air flow in the air inlet pipe 6 in real time, ensuring that the pressure of the gas is the required pressure when the gas is mixed with the material. At the same time, for convenience of control, a controller can be set for the foaming device, and the pressure valve, the air source device and the pump 1 are all electrically connected to the controller. A display screen can also be set, and the display screen is electrically connected to the controller, so that operations can be directly performed on the display screen to set corresponding parameters, thereby adapting to the foaming of various materials.

[0029] The above are only the preferred embodiments of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present utility model.
