Description

Technical Field

[0001] The present invention relates to the technical field of raw material extraction, and particularly to a raw material extraction device for shampoo production. Background Art

[0002] Shampoo is the most widely used hair washing product and one of the most commonly used hair cosmetics. It is used to wash away the oil secreted by the human body attached to the scalp and hair, sweat stains, cells shed from the scalp, as well as foreign dust, microorganisms, residues of styling products, and bad odors, etc., to keep the scalp and hair clean and the hair beautiful. And spices are indispensable in the production raw materials of shampoo. However, the essence raw materials prepared by chemical methods are harmful to the human body. Therefore, in order to pursue high-quality essence raw materials, they are generally extracted from plants. The shampoo made from natural essential oils can better nourish the hair, has a more gentle smell, and does not cause any harm to the body.

[0003] The patent with the publication number of "CN217516903U" and the name of a raw material extraction device for shampoo production includes a shredding box and a shredding device. The shredding box has a feed inlet and a discharge outlet, and also includes an extraction device. The extraction device includes an extraction box, a feed pipe, a filter plate, a pressing assembly, and a liquid outlet pipe. The extraction box is connected to the shredding box through the feed pipe and is located on one side of the shredding box close to the feed pipe. The feed pipe is connected to the extraction box in a through manner and is also connected to the shredding box in a through manner and is located between the extraction box and the shredding box. The filter plate is fixedly connected to the extraction box and is located on one side close to the bottom inside the extraction box. The pressing assembly is connected to the extraction box and is located on the side of the extraction box away from the filter plate. The liquid outlet pipe is connected to the extraction box in a through manner and is located at the bottom of the extraction box, achieving the effect of extracting the essential oil from the plant peel and improving the oil yield.

[0004] Currently, during the use of existing equipment for extracting plant raw materials, it is impossible to effectively and fully break plant cells. Relying solely on squeezing the plant raw materials, it is difficult to fully extract the plant essential oil inside, and the pressing extraction effect is average. Moreover, after pressing out the essential oil, it is inconvenient to separate the essential oil from the plant raw materials. Most existing equipment uses the method of filtering with a filter screen, but a large amount of plant raw materials piling up on the filter screen will cause the filter screen to become blocked, reducing the extraction effect, and the plant raw materials piling up on the filter screen are ultimately inconvenient to take out. Therefore, a raw material extraction device for shampoo production is proposed. Summary of the Invention

Detailed Description of the Invention

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0032] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0033] Embodiment:

[0034] Refer to Figures 1-9 , a raw material extraction device for shampoo production, including an extraction tank 1. The inner wall of the extraction tank 1 is fixedly connected with a pressing plate 2. The pressing plate 2 is arranged in a concave shape to better extract plant raw materials. Above the pressing plate 2, there is a pressing assembly 3. The pressing assembly 3 is used for pressing and extracting essential oils from plant raw materials; it also includes a filter sieve mechanism 4. The filter sieve mechanism 4 is arranged in the pressing plate 2 and is used for filtering and screening essential oils and raw material residues.

[0035] Refer to Figures 1-5 , Figures 7-9 , wherein, the pressing assembly 3 includes a pressing block 31. The top of the pressing block 31 is fixedly connected with a pressing shaft 32. The top of the extraction tank 1 is fixedly connected with a driving motor 33. The output shaft of the driving motor 33 penetrates into the extraction tank 1 and is fixedly connected with a telescopic sleeve 34. A limiting chute 341 is opened in the telescopic sleeve 34. A limiting slider 342 is slidably connected in the limiting chute 341. Among them, the limiting slider 342 is inserted into the limiting chute 341, and only vertical relative sliding and rotation together are possible between the two, ensuring that the power of the output shaft of the driving motor 33 is completely transmitted to the pressing shaft 32, improving the grinding and pressing effect. The top end of the pressing shaft 32 penetrates into the limiting chute 341 and is fixedly connected with the bottom of the limiting slider 342. And a first spring 343 is fixedly connected between the top of the limiting slider 342 and the limiting chute 341. A guiding ring 35 is fixedly connected inside the extraction tank 1. A lifting plate 351 is fixedly connected to the side wall of the pressing shaft 32, and the lifting plate 351 slides along the surface of the guiding ring 35;

[0036] Through the setting of the above structure, when the lifting plate 351 rotates along the guiding ring 35 to the jacking block 353, it will move along the inclined surface of the jacking block 353 to its top, thereby lifting the pressing shaft 32 upward, so that the top end of the pressing shaft 32 pushes the limiting slider 342 to move upward along the limiting chute 341. In this way, the whole pressing block 31 is lifted upward, so that the fitting surface state between the pressing block 31 and the pressing plate 2 is opened. At this time, the plant raw materials on the side wall of the pressing plate 2 will slide down to the bottom of its groove along the trend. Subsequently, the lifting plate 351 slides down from above the jacking block 353 again, and the pressing block 31 will fall and press the plant raw materials in the bottom of the groove of the pressing plate 2. As described above, while the pressing block 31 rotates, it will continuously move up and down reciprocally, so as to fully grind and press the plant raw materials that slide to the bottom of the groove of the pressing plate 2, effectively improving the extraction effect of plant essential oil.

[0037] Wherein, first air chambers 352 are arranged on both sides of the guiding ring 35. A jacking block 353 is slidably connected in the first air chamber 352. A second spring 354 is fixedly connected between the bottom of the jacking block 353 and the first air chamber 352. Both sides of the jacking block 353 are obliquely arranged. The maximum retraction distance of the second spring 354 is less than the height of the jacking block 353 exceeding the surface of the guiding ring 35. In this way, while ensuring the air pressure effect, it can also make the lifting plate 351 pull the pressing block 31 to move upward. And a plurality of groups of air blowing holes 355 are arranged at equal intervals at the bottom of the first air chamber 352. Preferably, the number of the air blowing holes 355 here is four groups. The output ends of the four groups of air blowing holes 355 are all vertically downward. A second air chamber 311 is arranged at the bottom of the pressing block 31. A pressure block 312 is slidably connected in the second air chamber 311. A third spring 313 is fixedly connected between the top of the pressure block 312 and the second air chamber 311. A guide air pipe 314 is fixedly connected to the outer wall of the pressing block 31, and the guide air pipe 314 is communicated with the inner cavity of the second air chamber 311. Three groups of guide air pipes 314 are arranged at equal intervals along the center of the pressing block 31, and the output ends of the guide air pipes 314 are obliquely downward. A limiting ring 315 is fixedly connected in the second air chamber 311. The distance from the bottom of the limiting ring 315 to the bottom of the pressing block 31 is equal to the thickness of the pressure block 312;

[0038] With the above - mentioned structure set, when the lifting plate 351 climbs onto the jacking block 353, the jacking block 353 will retract a certain distance into the first air chamber 352, thereby compressing the gas in the first air chamber 352. And this part of the gas will be blown out downward along the air - blowing holes 355. When the pressing block 31 falls and presses, the pressure block 312 will retract into the second air chamber 311, and finally the pressure block 312 will be flush with the bottom of the pressing block 31 to ensure the pressing effect. The retraction of the pressure block 312 will squeeze the gas in the second air chamber 311, causing this part of the gas to be blown out along the air guide pipe 314. Through the blowing action of the air - blowing holes 355 and the air guide pipe 314 above, a downward air flow thrust is generated above the pressing plate 2, enabling the plant raw materials to slide more quickly to the bottom of the groove of the pressing plate 2, effectively improving the squeezing efficiency, and effectively preventing plant debris from adhering to the inner walls of the extraction box 1 and the pressing plate 2, thereby improving the cleanliness of the inner walls of the extraction box 1 and the pressing plate 2 and reducing the production losses caused by raw material adhesion;

[0039] Refer to Figures 2-4 and Figure 7 As shown in, a material - guiding plate 5 is fixedly connected to the inner wall of the extraction box 1. The material - guiding plate 5 is inclined, which is convenient for the plant raw materials to fall quickly. The material - guiding plate 5 forms an annular cavity around the pressing shaft 32. A cutting blade 51 is fixedly connected to the outer wall of the pressing shaft 32 located in the annular cavity, and two groups of cutting blades 51 are provided above and below. With the setting of the two groups of cutting blades 51, the plant raw materials can be crushed to a greater extent;

[0040] With the above - mentioned structure set, when the pressing shaft 32 rotates and the plant raw materials fall along the material - guiding plate 5 into the cavity where the two groups of cutting blades 51 are located, they will be chopped up, thereby rupturing the plant cells, making it more convenient for subsequent oil extraction and improving the squeezing effect.

[0041] Refer to Figure 4 、 Figure 6 As shown in, the filter - sieve mechanism 4 includes a filter - sieve pipe 41. A filter - sieve groove 42 is formed at the bottom of the pressing plate 2. The filter - sieve pipe 41 is slidably connected in the filter - sieve groove 42. A top - sealing plate 411 is fixedly connected to the top of the filter - sieve pipe 41. A filter - sieve net 412 is fixedly connected to the upper part of the side wall of the filter - sieve pipe 41. The filter - sieve net 412 is communicated with the inner cavity of the filter - sieve pipe 41. A limiting section is arranged in the middle of the filter - sieve groove 42. A positioning ring 413 is fixedly connected to the outer wall of the filter - sieve pipe 41. The positioning ring 413 slides in the limiting section. When the positioning ring 413 fits to the bottom of the limiting section, the top - sealing plate 411 is flush with the surface of the pressing plate 2. A fourth spring 414 is sleeved on the filter - sieve pipe 41. The two ends of the fourth spring 414 are respectively fixedly connected to the positioning ring 413 and the top of the limiting section;

[0042] With the above structure set, when the crushed plant raw materials are ground and pressed by the pressing block 31, the essential oil inside will gradually flow out and gather at the bottom of the groove of the pressing plate 2. During the process of the pressing block 31 being lifted upward, by the rebounding effect of the fourth spring 414, the filter sieve tube 41 will move upward and extend into the pressing plate 2, making the filter sieve 412 on the side wall of the filter sieve tube 41 communicate with the bottom of the groove of the pressing plate 2. At this time, the pressed essential oil will enter the filter sieve tube 41 along the filter sieve 412, realizing the separation between the plant essential oil and the plant raw materials, improving the extraction quality of the plant essential oil. And with the downward flowing air flow generated in the air blowing hole 355 and the air guide pipe 314, it will be guided along the inner wall of the pressing plate 2 to the filter sieve tube 41, thereby promoting the essential oil to pass through the filter sieve 412 more quickly and improving the extraction speed of the plant essential oil;

[0043] In addition, when the pressing block 31 is pressed down again, it will touch the top sealing plate 411 of the filter sieve tube 41, making the filter sieve tube 41 retract into the filter sieve groove 42 again. With the setting of the positioning ring 413, finally the top sealing plate 411 will be flush with the bottom of the groove of the pressing plate 2 and can provide a stable pressing effect, so as to block the filter sieve groove 42 during pressing, ensuring the pressing strength at the bottom of the groove of the pressing plate 2, and also effectively preventing the plant raw material residues from being squeezed into the filter sieve 412, improving the filtering effect. During the reciprocating telescopic process of the filter sieve tube 41, by the friction between the filter sieve 412 and the inner wall of the filter sieve groove 42, the plant residues attached to the filter sieve 412 will be effectively scraped off, improving the filtering effect of the filter sieve 412.

[0044] Refer to Figure 3 、 Figure 4 , in which, a diversion frustum 6 is fixedly connected to the bottom of the extraction box 1, and discharge pipes 61 are communicated with all around the extraction box 1. Thus, the plant essential oil dripping downward along the filter sieve tube 41 will finally flow to the discharge pipes 61 all around along the diversion frustum 6, facilitating the extraction of the plant essential oil and improving the convenience of material extraction.

[0045] Refer to Figure 1 、 Figure 3 and Figure 6 , in which, a closed groove 7 is opened at the bottom of the groove of the pressing plate 2, a slag discharge pipe 71 is communicated with the bottom of the closed groove 7, the closed groove 7 penetrates and communicates to the outside of the extraction box 1, and a plugging plate 72 is inserted into the closed groove 7. Thus, pulling the plugging plate 72 makes the closed groove 7 communicate with the slag discharge pipe 71. At this time, water is filled downward from the top of the extraction box 1 and the pressing block 31 is in the lifted state. At this time, the water will flow out along the filter sieve tube 41 and the slag discharge pipe 71. The water flowing out of the filter sieve tube 41 carries a certain amount, and the water flowing out of the slag discharge pipe 71 will carry out the plant residues, realizing the discharge of the raw materials, facilitating cleaning, and improving the use effect.

[0046] Referring to Figures 1-9 , in the present invention, when in use, plant raw materials are put into the extraction tank 1 from the hoppers on both sides of the top of the extraction tank 1, and at the same time, the driving motor 33 is started to drive the pressing shaft 32 to rotate. At this time, the two groups of cutting blades 51 will rotate together. When the plant raw materials fall into the cavity where the two groups of cutting blades 51 are located along the material guiding plate 5, they will be chopped, so that plant cells are broken, which is more convenient for subsequent oil pressing and improves the pressing effect; then the chopped plant raw materials will fall onto the pressing block 31, and the pressing block 31 will rotate together with the pressing shaft 32. Under the action of the rotational centrifugal force, the plant raw materials will be thrown towards the side wall of the pressing disc 2. At this time, when the lifting plate 351 rotates along the guiding ring 35 to the jacking block 353, it will move along the inclined surface of the jacking block 353 to its top, thereby lifting the pressing shaft 32 upward, so that the top end of the pressing shaft 32 pushes the limiting slider 342 to move upward along the limiting chute 341. In this way, the whole pressing block 31 is lifted upward, so that the fitting surface state between the pressing block 31 and the pressing disc 2 is opened. At this time, the plant raw materials on the side wall of the pressing disc 2 will slide down to the bottom of its groove. When the lifting plate 351 climbs onto the jacking block 353, the jacking block 353 will retract a certain distance into the first air chamber 352, thereby compressing the gas in the first air chamber 352, and this part of the gas will be blown out downward along the air blowing holes 355. And when the pressing block 31 falls and presses, the pressure block 312 will retract into the second air chamber 311, and finally the pressure block 312 will be flush with the bottom of the pressing block 31 to ensure the pressing effect. The retraction of the pressure block 312 will squeeze the gas in the second air chamber 311, so that this part of the gas is blown out along the air guide pipe 314. Through the blowing action of the air blowing holes 355 and the air guide pipe 314 above, a downward air flow thrust is generated above the pressing disc 2, so that the plant raw materials slide down to the bottom of the groove of the pressing disc 2 more quickly, effectively improving the pressing efficiency, and effectively preventing plant debris from adhering to the inner walls of the extraction tank 1 and the pressing disc 2, thereby improving the cleanliness of the inner walls of the extraction tank 1 and the pressing disc 2, reducing the production loss caused by raw material adhesion. And as described above, while rotating, the pressing block 31 will continuously move up and down reciprocally, so as to fully grind and press the plant raw materials that slide to the bottom of the groove of the pressing disc 2, effectively improving the extraction effect of plant essential oil;

[0047] When the crushed plant raw materials are ground and pressed by the pressing block 31, the essential oil inside will gradually flow out and gather at the bottom of the groove of the pressing plate 2. During the upward lifting process of the pressing block 31, due to the elastic return of the fourth spring 414, the filter sieve tube 41 will move upward and extend into the pressing plate 2, making the filter sieve 412 on the side wall of the filter sieve tube 41 communicate with the bottom of the groove of the pressing plate 2. At this time, the pressed essential oil will enter the filter sieve tube 41 along the filter sieve 412, realizing the separation between the plant essential oil and the plant raw materials, improving the extraction quality of the plant essential oil, and then flowing downward along the inner cavity of the filter sieve tube 41 to the diversion frustum 6, and finally flowing to the discharge pipes 61 around along the diversion frustum 6, thus completing the extraction of the essential oil from the plant raw materials. When the pressing block 31 presses down again, it will touch the top sealing plate 411 of the filter sieve tube 41, making the filter sieve tube 41 retract into the filter sieve groove 42 again. With the setting of the positioning ring 413, finally the top sealing plate 411 is flush with the bottom of the groove of the pressing plate 2 and can provide a stable pressing effect, so as to block the filter sieve groove 42 during pressing, ensure the pressing strength at the bottom of the groove of the pressing plate 2, and also effectively prevent the plant raw material residues from being squeezed into the filter sieve 412, improving the filtering effect. Moreover, during the reciprocating telescopic process of the filter sieve tube 41, due to the friction between the filter sieve 412 and the inner wall of the filter sieve groove 42, the plant residues attached to the filter sieve 412 will be effectively scraped off, further improving the filtering effect of the filter sieve 412. Finally, after taking out the plant essential oil from the discharge pipe 61, pull the sealing plate 72 to make the closed groove 7 communicate with the slag discharge pipe 71. At this time, water is filled from the top of the extraction box 1 downward, and the pressing block 31 is in the lifted state. At this time, the water will flow out along the filter sieve tube 41 and the slag discharge pipe 71. The water flowing out of the filter sieve tube 41 carries a certain amount, and the water flowing out of the slag discharge pipe 71 will carry out the plant residues, realizing the discharge of the raw materials, facilitating cleaning, and improving the use effect.
