Technical Field

[0001] The utility model relates to the technical field of quantitative devices, in particular to an adjustable powder quantitative sampling device. Background Art

[0002] In application scenarios where a fixed mass of powder needs to be weighed repeatedly, such as in the process of precision ceramic pressing, operators are often required to weigh a fixed amount of granulated powder each time, fill it into the mold, and then dry press it. This operation consumes a lot of time and energy of the operator, which is not conducive to improving production efficiency.

[0003] CN219046024U discloses a powder quantitative sampling spoon, in which the sampling spoon part is fixed and unchanged, and a scraping device is mainly designed to reset after scraping by pushing a spring.

[0004] CN211347528U discloses a single-point quantitative sampler for medicinal powder, comprising a sampler housing with a convex cross-sectional shape and a conical bottom end, a spring mounting cavity arranged at the upper part of the sampler housing, a sampling cavity arranged at the lower part of the sampler housing and connected to the spring mounting cavity, a first handle arranged at the top edge of the sampler housing, a limiting bead arranged at the upper part of the sampler housing, a second handle with one end sleeved in the spring mounting cavity and in a T shape, a spring sleeved at the outer edge of the second handle and placed in the spring mounting cavity, a second spring baffle arranged at the upper part of the spring and fixed on the second handle, a first spring baffle arranged at the lower part of the spring, a circular hole in the center and fixed at the upper part of the sampling cavity, a pressing plate arranged below the first spring baffle, installed at the bottom of the second handle and adapted to the inner diameter of the sampling cavity, and a sealing plate sleeved at the outer edge of the upper part of the sampler housing, arranged corresponding to the sampling cavity and used to limit the size of the opening of the sampling cavity. Although this patent can be used for sampling solid powder samples, it has a relatively complex structure, is not easy to disassemble and maintain, has a high manufacturing cost, and is not suitable for large-scale promotion.

[0019] Combination Figure 1The present embodiment provides an adjustable powder quantitative sampling device, including a quantitative cylinder 3, wherein a movable bottom plate 2 is arranged inside the quantitative cylinder 3, and the peripheral side of the movable bottom plate 2 is sealed and connected to the inner wall of the quantitative cylinder 3; scale lines 5 are arranged on the quantitative cylinder 3, and an adjusting device 1 is arranged below the movable bottom plate 2 for adjusting the height of the movable bottom plate 2 and thus adjusting the volume between the movable bottom plate 2 and the top opening of the quantitative cylinder 3; a scraper 7 device is arranged on one side of the top of the quantitative cylinder 3 for scraping the material beyond the top of the quantitative cylinder 3.

[0020] In this embodiment, the quantitative cylinder 3 can be set as a hollow cylindrical cylinder, and the material is transparent. A scale line 5 is set on the outside of the quantitative cylinder 3 to mark the capacity from top to bottom. Specifically, the starting point of the scale can be increased from the top of the quantitative cylinder 3 downward, so as to facilitate the volume from the top to the movable bottom plate 2. The movable bottom plate 2 is movably arranged inside the quantitative cylinder 3, and a sealing ring 11 is arranged on the peripheral side of the movable bottom plate 2 to seal with the inner wall of the quantitative cylinder 3, so as to prevent the powder from falling into the area below the movable bottom plate 2. An adjusting device 1 is arranged below the movable bottom plate 2 to control the lifting and lowering of the movable bottom plate 2. Here, the adjusting device 1 can adopt an adjusting bolt, which is connected to the bottom of the quantitative cylinder 3 by threading. It is convenient to control a small range change by thread adjustment to achieve the effect of precise control. Of course, in other embodiments, automatic power control such as a telescopic cylinder, a push rod 6, and a stepping motor can also be adopted to achieve automatic adjustment.

[0021] A connection seat 4 is fixed to one side of the top of the quantitative cylinder 3, and the top surface of the connection seat 4 can be parallel to the top opening plane of the quantitative cylinder 3. Here, the scraper 7 device includes a connection seat 4, a push rod 6, and a scraper 7 arranged at one end of the push rod 6. The push rod 6 is movably arranged on the connection seat 4, and a handle 10 is arranged on the push rod 6 for manipulating the push rod 6 to move in a straight line. The scraper 7 is suitable for moving above the opening of the quantitative cylinder 3 to scrape the material beyond the quantitative cylinder 3. The length direction of the push rod 6 is parallel to the top opening plane of the quantitative cylinder 3, and the bottom surface of the scraper 7 is flush with the top opening of the quantitative cylinder 3, so that when the handle 10 is operated to make the scraper 7 pass over the quantitative cylinder 3, the material beyond the top opening of the quantitative cylinder 3 can be scraped flat, so as to ensure that the amount of material measured each time is the same, and the sampling efficiency can be improved. Here, a fixed bayonet 8 is arranged on the connection seat 4 to limit the push rod 6 to slide on the connection seat 4, so as to ensure that the push rod 6 moves along the top plane of the connection seat 4 when moving.

[0022] In a preferred embodiment, an elastic member 9 is provided at the other end of the push rod 6, and the elastic member 9 is suitable for driving the push rod 6 to reset after the scraper 7 scrapes the material flat. This arrangement enables the scraper 7 to automatically return to the initial position each time it is pushed to scrape off excess powder, so that it is convenient for use in the next sampling.

[0023] Through the scheme of this embodiment, the efficiency of quantitative sampling is improved, and it is convenient to control and adjust the required sampling amount.

[0024] It should be understood that the above are only preferred implementations of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions under the concept of the present utility model belong to the protection scope of the present utility model.
