For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0045] like Figure 1 , Figure 2As shown, the fineness detection device provided in this embodiment includes: a fixed trough body 100, a scraper fineness meter 200, a rotating shaft 300, a scraper 400 and a connecting member 500; the fixed trough body 100 is a concave structure, which is recessed downward in the middle to form a placement groove 110, and the scraper fineness meter 200 is placed in the placement groove 110. The scraper fineness meter 200 is configured as a cylindrical structure, and the outer circumferential surface of the scraper fineness meter 200 is provided with a groove 210, and the groove depth of the groove 210 gradually changes from a maximum value at one end to a zero value at the other end, that is, the groove depth of the groove 210 on the scraper fineness meter 200 is a gradual type.

[0046] The rotating shaft 300 is connected to the scraper fineness meter 200 , and both ends of the rotating shaft 300 are rotatably connected to the fixed tank body 100 , so that the rotating shaft 300 can rotate along its own axis, thereby driving the scraper fineness meter 200 to rotate.

[0047] One end of the connecting member 500 is connected to the fixed trough body 100, and the other end of the connecting member 500 is connected to the scraper 400. The scraper 400 is perpendicular to the tangent of the scraper fineness meter 200 and pressed against the scraper fineness meter 200. When the rotating shaft 300 rotates along its own axis, the scraper fineness meter 200 rotates, and the scraper 400 scrapes off the sample on the rotating shaft 300, forming a sample film in the groove 210 of the scraper fineness meter 200. The fineness of the sample particles is measured from the lines generated in the sample film.

[0048] It should be noted that in order to ensure that the scraper 400 first contacts the deepest part of the groove 210, the rotation direction of the rotating shaft 300 during fineness detection is opposite to the direction in which the groove depth of the groove 210 gradually decreases. Specifically, when performing fineness detection, the rotating shaft 300 rotates in a clockwise direction, and the groove depth of the groove 210 gradually decreases in a counterclockwise direction. Conversely, when performing fineness detection, the rotating shaft 300 rotates in a counterclockwise direction, and the groove depth of the groove 210 gradually decreases in a clockwise direction.

[0049] To facilitate the rotation of the rotating shaft 300 , in an optional embodiment, a rotating rocker 800 is connected to any end of the rotating shaft 300 . The user uses the rotating rocker 800 to rotate the rotating shaft 300 , thereby driving the scraper fineness meter 200 to rotate for fineness detection.

[0050] The fineness detection device provided in this embodiment fixes the position of the scraper 400 by the connecting member 500, so that the scraper 400 is always at a vertical angle to the scraper fineness meter 200, and because the cylindrical scraper fineness meter 200 is installed on the rotating shaft 300, the rotation of the rotating shaft 300 can drive the scraper fineness meter 200 to rotate, and the scraper 400 can scrape the scraper fineness meter 200, and the groove 210 on the scraper 400 fineness meter forms a sample film, and the fineness of the sample particles is measured from the lines generated in the sample film. The overall device is easy to use and the measurement is more accurate, which alleviates the technical problem in the prior art that the scraper fineness meter 200 is prone to inaccurate measurement results due to factors such as personnel changes, different angles, and different forces, thereby affecting the quality of subsequent products.

[0051] On the basis of the above embodiments, in an optional implementation manner, the fineness detection device provided in this embodiment further includes a fixing clamp 600; the fixing clamp 600 is arranged at one end of the connecting member 500 away from the fixed trough body 100, and the fixing clamp 600 is used to fix the scraper 400. The scraper 400 is fixed by the fixing clamp 600 to ensure that the sample can be scraped off by the scraper 400 when the scraper fineness meter 200 rotates.

[0052] Specifically, the fixing clamp 600 includes a clamp body 610, an upper clamp plate 620 and a lower clamp plate 630; the clamp body 610 is connected to the connecting member 500; the upper clamp plate 620 and the lower clamp plate 630 are arranged one above the other on the clamp body 610, and the upper clamp plate 620 and the lower clamp plate 630 are configured to be able to clamp the scraper 400. The clamp body 610, the upper clamp plate 620 and the lower clamp plate 630 are all steel plate structures, and the steel plate thickness of the upper clamp plate 620 and the lower clamp plate 630 is relatively thin, so that the upper clamp plate 620 and the lower clamp plate 630 have a certain elasticity, ensuring that the upper clamp plate 620 and the lower clamp plate 630 can clamp the scraper 400 together.

[0053] In addition, the fixing fixture 600 also includes a clamping bolt 640; the clamping bolt 640 passes through the upper clamping plate 620 and the lower clamping plate 630. When the scraper 400 needs to be clamped, the clamping bolt 640 is tightened, and the upper clamping plate 620 and the lower clamping plate 630 are driven closer to each other during tightening to clamp the scraper 400. When the scraper 400 needs to be removed, the clamping bolt 640 is loosened and the clamping bolt 640 is removed from the upper clamping plate 620 and the lower clamping plate 630. Since the tightening force of the clamping bolt 640 is lost, the upper clamping plate 620 and the lower clamping plate 630 cannot press the scraper 400, and the scraper 400 can be removed.

[0054] It should be noted that the clamping bolt 640 is used together with the nut, and the tightening force generated by the clamping bolt 640 and the nut acts on the upper clamping plate 620 and the lower clamping plate 630, so that the upper clamping plate 620 and the lower clamping plate 630 press the scraper 400.

[0055] In an optional embodiment, the connecting member 500 includes a connecting seat 510 and a connecting rod 520 ; the connecting seat 510 is fixed on the side wall of the fixed slot body 100 , the connecting rod 520 is connected to the connecting seat 510 , and the connecting rod 520 and the connecting seat 510 are vertically arranged.

[0056] Specifically, the connecting seat 510 is fixedly connected to the side wall of the fixed trough body 100, and a bolt hole is opened on the connecting seat 510. One end of the connecting rod 520 extends into the connecting seat 510. The connecting rod 520 can be connected to the connecting seat 510 by passing a screw through the bolt hole and the end of the connecting rod 520. The other end of the connecting rod 520 is connected to the fixing clamp 600. Since the connecting rod 520 and the connecting seat 510 are vertically arranged, it is ensured that the scraper 400 is always perpendicular to the tangent of the scraper fineness gauge 200.

[0057] like Figure 3 As shown, in an optional embodiment, the fineness detection device also includes a bearing assembly 700; the bearing assembly 700 is installed on the side wall of the fixed trough body 100, and the bearing assembly 700 is used to enable the rotating shaft 300 to rotate along its own axial direction, providing rotational freedom for the rotating shaft 300.

[0058] In an optional embodiment, the fineness detection device further includes a mounting bolt 710 ; the mounting bolt 710 passes through the bearing assembly 700 and extends into the fixed slot body 100 , so that the bearing assembly 700 can be connected to the fixed slot body 100 .

[0059] Specifically, the bearing assembly 700 includes a bearing seat and a bearing body. The bearing body is disposed in the bearing seat. The bearing seat is fixed to the fixed groove body 100 by mounting bolts 710. The bearing body provides rotational freedom for the rotating shaft 300.

[0060] The fineness detection device provided in this embodiment ensures that the scraper 400 and the scraper fineness meter 200 form a vertical angle through the setting of the connecting member 500, so that the detection is more accurate; through the setting of the rotating shaft 300 and the rotating rocker 800, it is only necessary to rotate the rotating shaft 300 by rotating the rocker 800, thereby driving the scraper fineness meter 200 to rotate to achieve measurement, thereby avoiding inaccurate measurement results caused by personnel changes, the angle between the scraper 400 and the scraper fineness meter 200, and different operating forces.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
