The pair of mounting arms is arranged on the rack, and the mounting arms are rotatably mounted on the rack; the compression roller is connected with one end of the mounting arm and is arranged above the rotating shaft; the roller sleeve is arranged on the compression roller, and a bearing is arranged between the compression roller and the roller sleeve; the detection plate is arranged at the other end of the mounting arm; the displacement sensor is arranged on the rack and is in contact with one end of the detection plate; and the elastic reset piece is arranged on the rack and is in contact with the other end of the detection plate. When a ramie strip passes through the space between the rotating shaft and the roller sleeve, the ramie strip acts on the roller sleeve to lift the roller sleeve and drive the mounting arm to rotate by a certain angle, the displacement sensor measures the displacement of the detection plate and compares the displacement with a set value of a control center, then the conveying speed of the conveying mechanism is controlled, and it is ensured that the thickness of the generated ramie strip is uniform. The roller sleeve can flexibly rotate relative to the pressing roller through the bearing, and the hemp blocking condition is not prone to occurring.

Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a novel sliver feeding detection device. Background Art

[0002] The sliver forming process of flax is completed on a flax sliver former. During the sliver forming process of flax, bundles of "combed flax" are lapped end to end and evenly laid on a sliver laying curtain, fed into a drafting mechanism, and drawn and thinned into continuous slivers. Chinese Patent Application Publication No. CN117306030A discloses a sliver feeding inspection device for a sliver former, including a first rotating shaft and a pressing block. One end of the pressing block is circumferentially matched with a mounting shaft, and a second rotating shaft is installed at the other end. At the same time, the pressing block is also provided with a connecting plate, and a displacement sensor and an elastic reset member are respectively arranged at the upper and lower ends of the connecting plate. When the sliver passes between the first rotating shaft and the second rotating shaft, the thickness of the sliver is detected by the displacement of the pressing block, and then the speed of the conveying mechanism is controlled. However, in the actual production process, due to the large frictional resistance between the second rotating shaft and the pressing block, the rotation of the second rotating shaft is sluggish, and it is easy to cause sliver jamming. Content of the Utility Model

[0003] To overcome the deficiencies of the background art, the utility model provides a novel sliver feeding detection device, which solves the problem of easy sliver jamming in the existing sliver feeding detection device when detecting the thickness of the sliver.

Detailed implementation mode

[0027] The present utility model will be further described below in conjunction with the drawings and embodiments:

[0028] In the embodiment, as Figure 1 , Figure 2 , Figure 3 shown, the new type of sliver feeding detection device includes a frame 1 and a rotating shaft, and further includes:

[0029] A pair of mounting arms 2, arranged on the frame 1, and the mounting arms 2 are rotatably mounted on the frame 1;

[0030] A pressure roller 3, connected to one end of the mounting arm 2 and arranged above the rotating shaft;

[0031] A roller sleeve 4, arranged on the pressure roller 3, and a bearing 5 is arranged between the pressure roller 3 and the roller sleeve 4;

[0032] A detection plate 6, arranged at the other end of the mounting arm 2;

[0033] A displacement sensor 7, arranged on the frame 1 and located at one end of the detection plate 6;

[0034] An elastic reset member 8, arranged on the frame 1 and in contact with the other end of the detection plate 6.

[0035] An anti-slip groove is provided in the circumferential direction of the rotating shaft. When the sliver passes between the rotating shaft and the roller sleeve 4, the sliver acts on the roller sleeve 4 to lift the roller sleeve 4, thereby driving the mounting arm 2 to rotate through a certain angle. The displacement sensor 7 measures the displacement of the detection plate 6 and compares it with the set value of the control center to calculate whether the sliver is too thick or too thin, and then controls the conveying speed of the conveying mechanism to ensure the uniform thickness of the generated sliver; in the present utility model, the roller sleeve 4 can rotate relative to the pressure roller 3 flexibly through the bearing 5, and it is not easy to have the situation of sliver jamming.

[0036] In the embodiment, as Figure 2 , Figure 3 shown, a scraping plate mechanism for cooperating with the roller sleeve 4 is provided at the rear end of the roller sleeve 4. It is used to scrape off the sliver adhered to the surface of the roller sleeve 4 to ensure the detection accuracy.

[0037] In the embodiment, as Figure 2 , Figure 3As shown, the scraper mechanism includes a first mounting shaft 9. An installation block 10 is provided on the first mounting shaft 9. The installation block 10 is connected to an installation plate 11, and an elastic scraper 12 is installed on the installation plate 11. The elastic scraper 12 is a rubber scraper or a silica gel scraper. The elastic scraper 12 can better contact the outer surface of the roller sleeve 4, and thus scrape off the hemp adhered to the surface of the roller sleeve 4.

[0038] In the embodiment, as Figure 1 , Figure 2 , Figure 3 shown, the first mounting shaft 9 is rotatably installed on the frame 1. The installation block 10 is further provided with a limiting plate 13, and a telescopic element 14 for contacting one end of the limiting plate 13 is provided on the frame 1. The telescopic element 14 is a push-pull electromagnet, a cylinder or a hydraulic cylinder. By the telescopic element 14 acting upward on one end of the limiting plate 13, the other end of the limiting plate drives the first mounting shaft 9 to rotate, and then drives the elastic scraper 12 away from the roller sleeve 4, facilitating the falling of the hemp between the elastic scraper 12 and the roller sleeve 4, and preventing the hemp from accumulating at the elastic scraper 12 and the roller sleeve 4.

[0039] In the embodiment, as Figure 1 , Figure 2 shown, it further includes a second mounting shaft 15 rotatably installed on the frame 1. A cam 16 for contacting the top surface of the mounting arm 2 is installed on the second mounting shaft 15, and a handle 17 is provided at one end of the second mounting shaft 15. By rotating the second mounting shaft 15 through the handle 17, the cam 16 presses down one end of the mounting arm 2, and one end of the mounting pressure roller 3 rises, facilitating the cleaning of the pressure roller 3.

[0040] In the embodiment, as Figure 1 , Figure 2 shown, retaining rings 18 for contacting the frame 1 are respectively provided at both ends of the second mounting shaft 15. The retaining rings 18 are used to prevent the second mounting shaft 15 from sliding left and right relative to the frame 1, resulting in the separation of the cam 16 from the mounting arm 2.

[0041] In the embodiment, as Figure 1 , Figure 4 shown, it further includes a housing 19 with an open front end. The elastic reset member 8 and the displacement sensor 7 are both arranged inside the housing 19. A connecting plate 20 for circumferentially cooperating with the housing 19 is provided on the frame 1. An arc-shaped hole 21 is provided on the connecting plate 20, and a first bolt passes through the arc-shaped hole 21 to connect with the housing 19. By adjusting the angle of the housing 19, it is ensured that the displacement sensor 7, the elastic reset member 8 and the detection plate 6 are vertically arranged, ensuring the accuracy of detection.

[0042] In the embodiment, as Figure 4 , Figure 5As shown, the elastic reset member 8 is a spring. An installation sleeve 22 for cooperating with the spring is installed on the detection plate 6. A stop block 23 for contacting one end of the spring is provided in the installation sleeve 22. A second bolt 24 is provided at the top of the installation sleeve 22, and the bottom surface of the second bolt 24 contacts the stop block 23. By rotating the second bolt 24 to raise or lower the stop block 23, the elastic force of the spring can be adjusted to the optimal state, improving the accuracy of detection.

[0043] Obviously, the above embodiments of the present invention are merely examples for explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, based on the above description, other different forms of changes or modifications can be made. It is not necessary and impossible to list all implementation manners here. And these obvious changes or modifications derived from the essence of the present invention still fall within the protection scope of the present invention.
