[0025] Figure 1 is a schematic diagram of a structure of an automated powder scraping device in embodiments of the present disclosure. In Figure 1 In the above-mentioned embodiments, the transverse direction is the first direction, and the longitudinal direction is the second direction.

[0026] In embodiments of the present disclosure, the automated powder scraping device is used for performing a powder scraping operation on a sample. In some embodiments, the sample is a biological sample, a pharmaceutical sample, or a chemical sample. When the sample is a pharmaceutical sample, it can be a Western medicine sample, a traditional Chinese medicine sample, or other medicine sample having a medicinal effect, etc. For example, the traditional Chinese medicine sample includes Chinese medicinal materials, traditional Chinese medicine decoction pieces, Chinese patent medicines, semi-finished products of traditional Chinese medicines, medicinal plants, etc.

[0027] As shown in Figure 1 The automated powder scraping device includes a mounting seat 11 and a scraper 12 disposed on the mounting seat 11. The scraper 12 includes a transverse blade extending in the transverse direction and a longitudinal blade extending in the longitudinal direction.

[0028] The first pre-pressing mechanism supports the mounting seat 11 in the transverse direction. When the longitudinal blade of the scraper 12 contacts the sample container, the first pre-pressing mechanism can provide a transverse support force to the mounting seat 11 and the scraper 12, so that the longitudinal blade of the scraper has sufficient force to scrape the powder. At the same time, the first pre-pressing mechanism can also provide a buffer to the mounting seat 11 and the scraper 12 in the transverse direction, so that the longitudinal blade is uniformly stressed when it contacts the sample container, and ensures that the longitudinal blade of the scraper 12 can effectively scrape the powder.

[0029] The second pre-pressing mechanism supports the mounting base 11 in the longitudinal direction, and can provide a longitudinal supporting force to the mounting base 11 and the scraper 12 when the transverse blade of the scraper 12 contacts the sample container, so that the transverse blade of the scraper has enough force to scrape the powder; at the same time, the second pre-pressing mechanism can also provide a buffer to the mounting base and the scraper 12 in the longitudinal direction, so that the transverse blade is uniformly stressed when it contacts the sample container, and the transverse blade of the scraper 12 can effectively scrape the powder.

[0030] In the embodiments of the present disclosure, when the transverse blade and the longitudinal blade of the scraper 12 contact the sample container at the same time, for example, the transverse blade contacts the bottom of the sample container and the longitudinal blade contacts the sidewall of the sample container, the first pre-pressing mechanism and the second pre-pressing mechanism can work at the same time, respectively providing a supporting force and a buffer to the longitudinal blade and the transverse blade of the scraper 12, so that the scraper can have enough force to scrape the powder on the bottom and the sidewall of the sample container, and the powder on the bottom and the sidewall of the sample container can be uniformly stressed, thereby effectively reducing the residual powder and improving the transfer rate of the powder.

[0031] In some embodiments, when the automatic powder scraping device provided by the embodiments of the present disclosure is used for automatic powder scraping, the transfer rate of the powder can reach more than 95%.

[0032] In some embodiments, as shown in Figure 1 the automatic powder scraping device further includes a connecting plate 6, the mounting base 11 is arranged on one side of the connecting plate 6 and coupled with the connecting plate 6; the first pre-pressing mechanism is arranged on the same side of the connecting plate 6 as the mounting base 11, and the second pre-pressing mechanism is arranged on the opposite side of the connecting plate 6 from the mounting base 11.

[0033] In some embodiments, as shown in Figure 1 the first pre-pressing mechanism includes a guide rail 13 arranged on the connecting plate 6 and extending in the transverse direction, and a first elastic component arranged at one end of the guide rail 13; the mounting base 11 is coupled with the guide rail 13 and connected with the first elastic component, and the first elastic component can provide elastic support to support the mounting base 11 in the transverse direction and provide a buffer.

[0034] As shown in Figure 1 the guide rail 13 includes a guide rail body and a sliding block, and the sliding block can slide in the transverse direction on the guide rail body; the first elastic component includes a baffle 7 and a first elastic piece, one end of the first elastic piece is connected with the baffle 7, and the other end is connected with the mounting base 11.

[0035] In the embodiments of the present disclosure, the mounting base 11 and the sliding block can be an integral structure, for example, a sliding groove is arranged on the mounting base 11, the sliding groove cooperates with the guide rail body to enable the mounting base 11 to slide in the transverse direction on the guide rail body; the mounting base 11 and the sliding block can also be independent components. The embodiments of the present disclosure do not make special limitations on this.

[0036] AsFigure 1 As shown, the mounting base 11 includes a first mounting portion extending laterally and a second mounting portion extending longitudinally; the slider is connected to the first mounting portion, and the first elastic member is connected to the second mounting portion.

[0037] like Figure 1 As shown, the first elastic component also includes a first guide shaft 9, and the first elastic element includes a first compression spring 10; a through hole is provided on the baffle 7; one end of the first guide shaft 9 passes through the through hole on the baffle 7 and is connected to the second mounting part, and the first compression spring 10 is sleeved on the first guide shaft 9; the other end of the first guide shaft 9 is provided with a first limiting part 8, the size of which is larger than the size of the through hole on the baffle 7. When the longitudinal blade of the scraper 12 contacts the sample container, the mounting base 11 moves laterally to the right, and the first guide shaft 9 can move laterally to the right in the through hole on the baffle 7, thereby squeezing the first compression spring 10, so that the compression deformation of the first compression spring 10 provides a lateral leftward support force to the mounting base 11 and the scraper 12; when the mounting base 11 moves laterally to the left, since the size of the first limiting part 8 is larger than the size of the through hole on the baffle 7, the first guide shaft 9 can be prevented from sliding out of the through hole on the baffle 7, limiting the maximum distance of the mounting base 11 moving laterally to the left, thus playing a limiting role.

[0038] In this embodiment, the first limiting part 8 and the first guide shaft 9 can be an integral structure; the first limiting part 8 and the first guide shaft 9 can also be independent of each other, for example, assembled together by threaded connection.

[0039] In some embodiments, such as Figure 1 As shown, the second pre-compression mechanism includes a base plate 1 and a second elastic component. The base plate 1 is disposed on the opposite side of the connecting plate 6 and the mounting base 11. The second elastic component is disposed between the base plate 1 and the connecting plate 6 and is connected to the base plate 1 and the connecting plate 6 respectively. The second elastic component can provide elastic support, support the connecting plate 6 longitudinally and provide buffering, thereby providing longitudinal support force and buffering for the mounting base 11 and the scraper 12.

[0040] like Figure 1 As shown, the second elastic component includes a second guide shaft 3 and a second compression spring 5. The second guide shaft 3 extends longitudinally and is slidably engaged with the base plate 1 or the connecting plate 6. For example, one end of the second guide shaft 3 is slidably engaged with the base plate 1, allowing it to slide relative to the base plate 1 longitudinally, while the other end is fixedly connected to the connecting plate 6, thereby enabling the base plate 1 and the connecting plate 6 to move relative to each other longitudinally; or one end of the second guide shaft 3 is slidably engaged with the connecting plate 6, allowing it to slide relative to the connecting plate 6 longitudinally, while the other end is fixedly connected to the base plate 1, thereby enabling the base plate 1 and the connecting plate 6 to move relative to each other longitudinally. The second compression spring 5 is disposed between the base plate 1 and the connecting plate 6, and is sleeved on the second guide shaft 3.

[0041] In the embodiments of the present disclosure, a plurality of second guide shafts 3 are arranged between the base plate 1 and the connecting plate 6, each second guide shaft 3 is sleeved with a second compression spring 5, and the plurality of second guide shafts are uniformly distributed on the plane of the base plate 1 or the connecting plate 6, so that the stress can be more uniform and the structure can be more stable.

[0042] In some embodiments, as shown in Figure 1 four second guide shafts 3 are arranged between the base plate 1 and the connecting plate 6, one end of each second guide shaft 3 is in sliding fit with the base plate 1, and the other end is fixedly connected with the connecting plate 6, a through hole is formed in the base plate 1, and one end of the second guide shaft 3 passes through the through hole in the base plate 1 and is in sliding fit with the base plate 1, and the other end is fixedly connected with the connecting plate 6; one end of the second guide shaft 3 away from the connecting plate 6 is provided with a second limiting portion 2, and the size of the second limiting portion 2 is greater than the size of the through hole in the base plate 1.

[0043] When the transverse blade of the scraper 12 contacts the sample container, the mounting seat 11 moves longitudinally upward, the connecting plate 6 drives the second guide shaft 3 to move longitudinally upward in the through hole in the base plate 1, so as to press the second compression spring 5 and make the second compression spring 5 compressively deform to provide a longitudinally downward supporting force for the mounting seat 11 and the scraper 12; when the mounting seat 11 moves longitudinally downward, since the size of the second limiting portion 2 is greater than the size of the through hole in the base plate 1, the second guide shaft 5 can be prevented from sliding out of the through hole in the base plate 1, the maximum distance of the mounting seat 11 moving longitudinally downward is limited, and a limiting effect is achieved.

[0044] As shown in Figure 1 a bearing seat 4 is further arranged on the through hole of the base plate 1, and the second guide shaft 3 passes through the bearing seat 4.

[0045] In some embodiments, one end of the second guide shaft 3 is in sliding fit with the connecting plate 6 and can slide along the longitudinal direction relative to the connecting plate 6, the other end is fixedly connected with the base plate 1, a through hole is formed in the connecting plate 6, one end of the second guide shaft 3 passes through the through hole in the connecting plate 6 and is in sliding fit with the connecting plate 6, the other end is fixedly connected with the base plate 1, and the second compression spring 5 is sleeved on the second guide shaft 3; one end of the second guide shaft 3 away from the base plate 1 is provided with a second limiting portion 2, and the size of the second limiting portion 2 is greater than the size of the through hole in the connecting plate 6.

[0046] In some embodiments, as shown in Figure 1 the automatic powder scraping device further comprises a connecting portion 14 for being connected with an automatic moving device such as a mechanical arm, so as to be driven by the automatic moving device such as the mechanical arm to perform automatic powder scraping.

[0047] In a second aspect, the embodiments of the present disclosure provide an automatic moving device, characterized in that the automatic moving device comprises a moving mechanism and the automatic powder scraping device of the first aspect of the embodiments of the present disclosure, and the automatic powder scraping device is connected with the moving mechanism.

[0048] In the embodiments of the present disclosure, the automatic powder scraping device can be detachably connected with the moving mechanism, or can be fixedly connected with the moving mechanism. The embodiments of the present disclosure do not make special limitation on this.

[0049] Example embodiments have been disclosed herein and, although the specific terms are employed, they are used in a generic sense only and should not be construed to be limited to the specific embodiments described herein. In some instances, those skilled in the art will appreciate that features, aspects and / or elements described in conjunction with a particular embodiment can be used singularly or in combination with other embodiments unless otherwise explicitly stated.
