Description

Technical Field

[0001] The invention relates to the technical field of grinding devices, and more specifically, to a grinding device and a grinding method for a nursing liquid raw material. Background Art

[0002] Care solution refers to a liquid that has the function of cleaning, maintaining, and repairing one or more parts of the human body, such as oral care, skin care, etc. During its manufacturing process, in order to ensure its effectiveness, Chinese medicine with corresponding functions is often added to it according to the difference in functions and used as the raw material of the care solution.

[0003] When adding Chinese medicine, it is usually necessary to use a grinding device to grind the Chinese medicine into powder first. Although the existing grinding device can complete the grinding work well, in the actual operation process, when the raw material is ground, the crushing cutter head rotates rapidly to crush the raw material, and the high-speed friction between the cutter head and the raw material will generate a large amount of heat, which makes the air pressure inside the grinding device greater than the external pressure. At the same time, the raw material will be ground into dry powder. This results in that when the sealing cover of the grinding device is opened, a part of the powdered raw material floating on the upper layer will float in the air under the action of air pressure, causing unnecessary waste. Another part of the raw material powder will adhere to the inner wall of the top cover and need to be collected manually. The operation is time-consuming, labor-intensive and inconvenient.

DETAILED DESCRIPTION

[0024] The subject matter described herein will now be discussed with reference to example implementations. It should be understood that the discussion of these implementations is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the present specification. Various examples may omit, replace, or add various processes or components as needed. In addition, the features described in some examples may also be combined in other examples.

[0025] like Figure 1 , Figure 5 , Figure 7 As shown, this embodiment discloses a care liquid raw material grinding device and grinding method, including: a housing 100, used to carry the care liquid raw material to be ground; a sealing cover 101 is detachably connected to the upper side of the housing 100; The crushing part 200 is installed at the bottom of the shell 100. The crushing part 200 includes a crushing cutter head 201 rotatably arranged at the bottom of the shell 100. The bottom of the shell 100 is installed with a driving device for driving the crushing cutter head 201 to rotate; The suction part 300 is arranged on the shell 100, and the suction part 300 includes a cover plate 301 arranged on the upper side of the shell 100. The middle part of the cover plate 301 is rotatably connected to the central axis 302, and the upper end of the central axis 302 is fixedly connected to the mounting plate 303. A pair of bellows 304 are detachably connected to the mounting plate 303, and the upper pipe openings of the bellows 304 are closed. The mounting plate 303 is connected to the lower pipe opening of the bellows 304. The cover plate 301 is penetrated by a number of through holes 305 corresponding to the number of the bellows 304, and the positions of the through holes 305 correspond to the positions of the lower pipe openings of the bellows 304.

[0026] The working principle and beneficial effects of the above technical solution are as follows: first, open the sealing cover 101, pour the dried Chinese medicinal materials into the inner bottom of the shell 100, and the overall amount shall not exceed two-thirds of the volume of the shell 100; then, turn the cover plate 301 upside down on the upper side of the shell 100, and cover the sealing cover 101; during the process of covering the sealing cover 101, squeeze the bellows 304 so that the bellows 304 is compressed.

[0027] Subsequently, the driving device is started to drive the crushing cutter head 201 to rotate at a high speed, quickly crushing and grinding the Chinese medicine raw materials in the shell 100 until they are ground into dry powder. At this time, due to the high-speed friction between the crushing cutter head 201 and the Chinese medicine raw materials during the grinding process, a large amount of heat is generated, making the air pressure inside the grinding device greater than the external pressure. A part of the raw materials ground into dry powder floats in the shell 100 under the action of air pressure and inertia.

[0028] At this time, the sealing cover 101 is opened, and the compressed bellows 304 is no longer suppressed by the sealing cover 101, and quickly returns to its original state. During the extension of the tube body, negative pressure is generated inside the tube body, and the raw material powder floating in the shell 100 is sucked into the bellows 304, and the pressure generated by the high temperature inside the shell 100 is released. At this time, the mounting plate 303 is rotated a quarter of a circle to stagger the through holes 305 on the bellows 304 and the cover plate 301, and the cover plate 301 can be removed. At this time, since the lower tube mouth of the bellows 304 is blocked by the mounting plate 303, the powder in the bellows 304 will not leak out. The cover plate 301 is turned over, the bellows 304 is removed, and the raw material powder inside can be poured out and collected.

[0029] It should be noted that when grinding the same kind of Chinese medicinal raw materials multiple times, in the early grinding process, it is only necessary to remove the cover plate 301, pour out the ground raw material powder in the shell 100, and add new raw material powder. The powder in the bellows 304 only needs to be removed after all the same kind of Chinese medicinal raw materials are ground, and the raw material powder inside can be collected.

[0030] This embodiment adopts the technical means of cooperating the crushing part 200 and the suction part 300. When the raw material is ground by the crushing cutter head 201 and the sealing cover 101 is opened, the compressed bellows 304 returns to its original state, and the raw material powder floating in the shell 100 is sucked into the bellows 304. Then the detachable bellows 304 is removed, and the powder inside is poured out and collected. This overcomes the shortcomings of the prior art and further improves the practicality of the device.

[0031] like Figure 6 , Figure 4 , Figure 7 As shown, in a specific embodiment: the lower end of the central axis 302 is fixedly connected with a first scraper strip 306, both ends of the first scraper strip 306 have a convex portion, and a pair of arc plates 307 are fixedly connected to the inner side of the upper edge of the shell 100, and each arc plate 307 is provided with a sliding groove for the corresponding convex portion to be embedded and slide.

[0032] The working principle and beneficial effects of the above technical solution are as follows: during installation, the cover plate 301 is turned upside down on the shell 100, and the position of the first scraper strip 306 is adjusted so that the two protrusions of the first scraper strip 306 avoid the corresponding curved plate 307, and then the mounting plate 303 is rotated. The mounting plate 303 drives the first scraper strip 306 to rotate through the central axis 302, so that the two protrusions of the first scraper strip 306 are respectively embedded in the slide grooves on the corresponding curved plate 307, until the two protrusions are respectively against the side walls of the corresponding curved plate 307, at this time, the lower pipe openings of the two bellows 304 just move to the position opposite to the corresponding through hole 305, after the grinding of the Chinese medicine raw materials is completed, while the mounting plate 303 is rotated, the central axis 302 synchronously drives the first scraper strip 306 to rotate synchronously, and the first scraper strip 306 scrapes off the raw material powder adhering to the inner wall of the cover plate 301 during the rotation process, without manual cleaning, saving human resources.

[0033] like Figure 7 As shown, in a specific embodiment: two second scraper strips 308 are fixedly connected to the first scraper strip 306, and the two second scraper strips 308 are symmetrically arranged.

[0034] The working principle and beneficial effects of the above technical solution are as follows: when there is no assistance from the second scraper bar 308, the first scraper bar 306 needs to rotate half a circle to scrape off the raw material powder on the inner wall of the cover plate 301, and to remove the cover plate 301, it only needs to rotate it a quarter of a circle. If one is careless, it is easy to rotate less than a quarter of a circle, resulting in missed scraping. With the assistance of the second scraper bar 308, it only needs to rotate a quarter of a circle, which is more consistent with the rotation radius of installing and removing the cover plate 301, and missed scraping will not occur, thereby improving the stability of the device.

[0035] like Figure 7As shown, in a specific embodiment: the mounting plate 303 is fixedly connected with a plurality of anti-slip ribs 309, and the plurality of anti-slip ribs 309 are symmetrically arranged.

[0036] The working principle and beneficial effects of the above technical solution are as follows: the provision of the anti-slip ribs 309 increases the friction of the mounting plate 303, making it easier and more labor-saving to rotate the mounting plate 303.

[0037] like Figure 6 As shown, in a specific embodiment: each bellows 304 is provided with an external thread at the lower end, and the corresponding position on the mounting plate 303 is provided with an internal thread matching the external thread.

[0038] The working principle and beneficial effects of the above technical solution are as follows: the arrangement of the external thread and the internal thread facilitates the installation and removal of the bellows 304 and improves the stability when the bellows 304 and the mounting plate 303 are connected.

[0039] like Figure 2 As shown, in a specific embodiment: the driving device includes a servo motor 202 fixedly mounted on the bottom of the housing 100 , and the output shaft of the servo motor 202 is fixedly connected to the crushing cutter head 201 .

[0040] The working principle and beneficial effects of the above technical solution are as follows: the servo motor 202 is started, and the output shaft of the servo motor 202 rotates, driving the crushing cutter head 201 to rotate synchronously, thereby crushing and grinding the Chinese medicine raw materials.

[0041] like Figure 2 , Figure 3 As shown, in a specific embodiment: a transverse axis 203 is fixedly connected to both sides of the servo motor 202, a base 204 is provided on the lower side of the housing 100, each transverse axis 203 is rotatably connected to the base 204, and a fastening handle 205 is threadedly connected to one of the transverse axes 203.

[0042] The working principle and beneficial effects of the above technical solution are as follows: when the amount of raw material to be ground is large, the raw material in the middle and upper layers is difficult to be ground due to the low position of the crushing cutter head 201. At this time, it is necessary to loosen the fastening handle 205, and then reciprocate the servo motor 202 around the horizontal axis 203 to make the shell 100 and the raw material therein shake, so that the grinding is more sufficient. When the amount of raw material to be ground is less than one-third of the volume of the shell 100, it is only necessary to tighten the fastening handle 205.

[0043] like Figure 2 As shown, in a specific embodiment: an electric control box 206 is installed on a side of the base 204 away from the fastening handle 205 , and the electric control box 206 is electrically connected to the servo motor 202 .

[0044] The working principle and beneficial effects of the above technical solution are as follows: the speed of the servo motor 202 can be adjusted by turning the adjustment button on the electric control box 206, and the on and off of the current can be controlled by the start button on the electric control box 206. At the same time, a plug for connecting a power supply is installed on the electric control box 206, which is not drawn in the figure.

[0045] like Figure 2 , Figure 3 As shown, in a specific embodiment: a first handle 207 is fixedly connected to the servo motor 202 , and a second handle 208 is fixedly connected to the cover plate 301 .

[0046] The working principle and beneficial effects of the above technical solution are: holding the first handle 207 and reciprocatingly rotating the servo motor 202 with the horizontal axis 203 as the center of the circle makes the operation more convenient, and the second handle 208 facilitates opening the sealing cover 101.

[0047] like Figure 2 As shown, in a specific embodiment: at least two fastening bolts 209 are installed on the cover plate 301 , and a clamping block is fixedly installed at a corresponding position of the housing 100 for fastening with the fastening bolts 209 .

[0048] The working principle and beneficial effects of the above technical solution are as follows: the fastening bolt 209 cooperates with the clamping block to tighten.

[0049] Working principle: First, open the sealing cover 101, pour the dried Chinese medicinal materials into the inner bottom of the shell 100, and the overall volume does not exceed two-thirds of the volume of the shell 100. Then, put the cover plate 301 upside down on the shell 100, and adjust the position of the first scraper 306 so that the two protrusions of the first scraper 306 avoid the corresponding curved plate 307. Then rotate the mounting plate 303, and the mounting plate 303 drives the first scraper 306 to rotate through the central axis 302, so that the two protrusions of the first scraper 306 are respectively embedded in the sliding grooves on the corresponding curved plate 307, until the two protrusions are respectively against the side walls of the corresponding curved plate 307. At this time, the lower pipe openings of the two bellows 304 just move to the position opposite to the corresponding through holes 305, and then cover the sealing cover 101. During the process of covering the sealing cover 101, the bellows 304 are squeezed so that the bellows 304 are compressed.

[0050] Subsequently, the servo motor 202 is started, and the output shaft of the servo motor 202 rotates, driving the crushing cutter head 201 to rotate at a high speed, quickly crushing and grinding the Chinese medicine raw materials in the shell 100 until they are ground into dry powder. At this time, due to the high-speed friction between the crushing cutter head 201 and the Chinese medicine raw materials during the grinding process, a large amount of heat is generated, making the air pressure inside the grinding device greater than the external pressure, and a part of the raw materials ground into dry powder floats in the shell under the action of air pressure and inertia.

[0051] At this time, the sealing cover 101 is opened, and the compressed bellows is no longer suppressed by the sealing cover 101, and quickly returns to its original state. During the extension of the tube body, negative pressure is generated inside the tube body, and the raw material powder floating in the shell is sucked into the bellows, and the pressure generated by the high temperature inside the shell is released. At this time, the mounting plate 303 is rotated a quarter of a circle to stagger the through holes 305 on the bellows 304 and the cover plate 301, and the cover plate 301 can be removed. At this time, since the lower tube mouth of the bellows 304 is blocked by the mounting plate 303, the powder in the bellows will not leak out. The cover plate 301 is turned over, the bellows 304 is removed, and the raw material powder inside can be poured out and collected.

[0052] After the raw material is ground by the crushing cutter head 201, when the sealing cover 101 is opened, the compressed bellows 304 returns to its original state, and the raw material powder floating in the shell is sucked into the bellows 304. Then the detachable bellows 304 is removed, and the powder inside is poured out and collected.

[0053] After the Chinese medicine raw materials are ground, while the mounting plate 303 is rotated, the central shaft 302 synchronously drives the first scraper 306 and the second scraper 308 to rotate synchronously for at least a quarter of a circle. During the rotation process, the first scraper 306 and the second scraper 308 scrape off the raw material powder adhered to the inner wall of the cover plate 301, and the powder adhered to the inner wall of the cover plate 301 is cleaned simultaneously.

[0054] The above describes an embodiment of the present invention, but this embodiment is not limited to the above specific implementation methods. The above specific implementation methods are merely illustrative and not restrictive. Under the guidance of this embodiment, ordinary technicians in this field can also make many forms, all of which are protected by this embodiment.

During the covering process of the sealing cover (101), the bellows (304) is squeezed, so that the bellows (304) is compressed; S2: Subsequently, the servo motor (202) is started, and the output shaft of the servo motor (202) rotates, driving the crushing blade head (201) to rotate at a high speed, and the Chinese medicine raw materials in the housing (100) are quickly crushed and ground until they are ground into a dry powder. At this time, due to the high-speed friction between the crushing blade head (201) and the Chinese medicine raw materials during the grinding process, a large amount of heat is generated, so that the air pressure inside the grinding device is greater than that outside, and a part of the raw materials ground into dry powder floats in the housing under the action of air pressure and inertia; S3: At this time, the sealing cover (101) is opened, and the compressed bellows (304) is no longer compressed by the sealing cover (101), and quickly returns to its original state. During the process of its tube body stretching, negative pressure is generated inside the tube body, and the raw material powder floating in the shell is sucked into the bellows (304), and the pressure generated by the high temperature inside the shell is released. At this time, the mounting plate (303) is rotated a quarter of a circle, so that the bellows (304) and the through holes (305) on the cover plate (301) are offset, and the cover plate (301) can be removed. At this time, since the lower tube opening of the bellows (304) is blocked by the mounting plate (303), the powder in the bellows (304) will not leak out. The cover plate (301) is turned over, the bellows (304) is removed, and the raw material powder inside can be poured out and collected; S4: After the raw material is ground by the crushing blade (201), the sealing cover (101) is opened, and the compressed bellows (304) returns to its original state, and the raw material powder floating in the shell (100) is sucked into the bellows (304). Then, the detachable bellows (304) is removed, and the powder inside is poured out and collected; S5: After the Chinese medicine raw materials are ground, while the mounting plate (303) is rotated, the central shaft (302) synchronously drives the first scraper (306) and the second scraper (308) to synchronously rotate at least a quarter of a circle. During the rotation process, the first scraper (306) and the second scraper (308) scrape off the raw material powder adhering to the inner wall of the cover plate (301), and the powder adhering to the inner wall of the cover plate (301) is cleaned up synchronously.
