Description

Technical Field

[0001] This utility model relates to the technical field of spinning, specifically to a feeding sliver density detection and adjustment device. Background Technology

[0002] Sliver uniformity is crucial to yarn quality. Currently, the industry uses the density composition of sliver at various points on the sliver to measure sliver uniformity. Therefore, during sliver production, it is necessary to constantly control and adjust the instantaneous density changes of the sliver to ensure uniformity.

[0003] In actual operation, an angular displacement sensor is installed on the upper crankshaft of the first guide roller (first extrusion roller). The upper crankshaft is elastically connected to the base through a tension spring. When the cotton sliver passes between the first and second guide rollers (first and second extrusion rollers), the thickness of the cotton sliver causes the upper crankshaft to rotate, which determines the angle of rotation of the upper crankshaft. The angular displacement sensor connected to the upper crankshaft generates a detection signal output according to the different rotation angles, thereby completing the detection operation. However, this process involves many parts and complicated procedures. Furthermore, cotton lint and debris can block the parts channels during cotton sliver production, easily leading to machine malfunctions. To address this problem, the existing solution is to clean the cotton sliver by scraping. However, in actual use, after scraping, the cotton lint is easily scattered by external airflow, causing air pollution and making cleaning difficult, thus affecting the detection effect.

[0004] Therefore, this utility model proposes a feeding cotton sliver density detection and adjustment device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a feeding sliver density detection and adjustment device, which can solve the following problems:

[0006] After being scraped off, the cotton fibers are easily scattered by external airflow, causing air pollution and making cleaning difficult, which affects the testing results.

[0007] To solve the above-mentioned technical problems, the present invention proposes the following technical solution:

[0008] A feeding swab density detection and adjustment device includes a first detection body and a second detection body fixedly connected. The tail end of the first detection body is fixedly connected to an outlet seat, and the outer end of the second detection body is fixedly connected to a feeding component. The outer end of the feeding component is fixedly connected to a feeding plate, and the bottom end of the feeding component is matched with a base assembly. The feeding component includes an integrally formed feeding sealing cover and a base plate. The front end of the feeding sealing cover has a feeding inlet, and the top of the feeding sealing cover is fixedly connected to a friction cylinder. An adsorption cylinder is embedded inside the friction cylinder. The base assembly includes a fixedly connected mounting base plate and a mounting base. From left to right, the surface of the mounting base plate is provided with a limit plate, an auxiliary seat, and a cotton guide wheel.

[0009] Furthermore, the feeding sealing cover is arranged in a trapezoidal shape, with the bottom plate extending horizontally outward along the tail end of the feeding sealing cover and located at the bottom of the second detection body.

[0010] Furthermore, the friction cylinder is longitudinally opened along the top surface of the feeding sealing cover, and one end of the friction cylinder is fixedly connected to an "L"-shaped support. The adsorption cylinder is set as a polyester cylinder, which is movably embedded in the friction cylinder. At the same time, the adsorption cylinder is located inside the upper part of the feeding sealing cover.

[0011] Furthermore, a drive motor is provided at the outer end of the adsorption cylinder, and the drive motor is also located on a support at one end of the friction cylinder.

[0012] Furthermore, two sets of limiting plates are arranged adjacent to each other, extending longitudinally along the surface of the mounting base plate, and one end of the limiting plate is fixedly connected to the edge of the mounting base plate.

[0013] Furthermore, the auxiliary seat is arranged in a trapezoidal protrusion and is also arranged longitudinally along the surface of the mounting base. A negative pressure adsorption mechanism is provided at the bottom of the auxiliary seat, and the negative pressure adsorption mechanism is located inside the mounting base.

[0014] Furthermore, the front end of the auxiliary seat is configured as an airflow inlet, which is flush with the limiting plate.

[0015] As can be seen from the above technical solution, the beneficial effects of this utility model are:

[0016] 1. This utility model uses a feeding sealing cover to facilitate the feeding of external cotton strips in a sealed state for testing operations, which can effectively prevent cotton lint from spilling out, thus ensuring the subsequent testing results. The friction cylinder and the adsorption cylinder work together to generate static electricity through friction to adsorb the cotton lint on the fed cotton strip.

[0017] 2. This utility model achieves the effect of limiting and guiding the fed cotton strip through the limiting plate, and achieves the effect of conveying airflow from the opposite direction of the cotton strip feeding through the auxiliary seat, thereby realizing the auxiliary operation of cleaning cotton lint on the fed cotton strip.

[0024] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0025] See Figure 1-3 As shown, a feeding swab density detection and adjustment device includes a first detection body 1 and a second detection body 3 fixedly connected. The tail end of the first detection body 1 is fixedly connected to an outlet seat 2. The outer end of the second detection body 3 is fixedly connected to a feeding component 4. The outer end of the feeding component 4 is fixedly connected to a feeding plate 5. The bottom end of the feeding component 4 is matched with a base assembly 11. The feeding component 4 includes an integrally formed feeding sealing cover 6 and a base plate 7. The front end of the feeding sealing cover 6 has a feeding inlet 10. The top of the feeding sealing cover 6 is fixedly connected to a friction cylinder 8. An adsorption cylinder 9 is embedded inside the friction cylinder 8. The base assembly 11 includes a fixedly connected mounting base plate 12 and a mounting base 16. From left to right, the surface of the mounting base plate 12 is provided with a limit plate 13, an auxiliary seat 14, and a cotton guide wheel 15.

[0026] In this embodiment of the utility model, the feeding sealing cover 6 is generally arranged in a trapezoidal shape. The bottom plate 7 extends horizontally outward along the tail end of the feeding sealing cover 6 and is located at the bottom of the second detection body 3. The friction cylinder 8 is longitudinally opened along the top surface of the feeding sealing cover 6, and one end of the friction cylinder 8 is fixedly connected to an "L"-shaped support. The adsorption cylinder 9 is a polyester cylinder that is movably embedded in the friction cylinder 8. The adsorption cylinder 9 is located at the upper part of the inside of the feeding sealing cover 6. The outer end of the adsorption cylinder 9 is equipped with a drive motor, which is also located on the support at one end of the friction cylinder 8. The feeding sealing cover 6 facilitates the feeding of external cotton strips in a sealed state for detection operations, effectively preventing cotton lint from spilling out and ensuring the subsequent detection effect. The friction cylinder 8 and the adsorption cylinder 9 work together to generate static electricity through friction to adsorb the cotton lint on the fed cotton strip.

[0027] When adsorbing cotton fibers in the fed cotton strip, the drive motor at the outer end of the adsorption cylinder 9 drives the adsorption cylinder 9 to rotate in the friction cylinder 8 to generate static electricity. As the external cotton strip is fed in, the static electricity adsorption of cotton fibers is achieved from the top position.

[0028] Two sets of limiting plates 13 are arranged adjacently, extending longitudinally along the surface of the mounting base plate 12. One end of the limiting plate 13 is fixedly connected to the edge of the mounting base plate 12. The auxiliary seat 14 is arranged in a trapezoidal protrusion, also extending longitudinally along the surface of the mounting base plate 12. A negative pressure adsorption mechanism is provided at the bottom of the auxiliary seat 14, which is located inside the mounting base 16. The front end of the auxiliary seat 14 is set as an airflow inlet, which is flush with the limiting plate 13. The limiting plate 13 achieves the effect of limiting and guiding the fed cotton strip, while the auxiliary seat 14 achieves the effect of conveying airflow in the opposite direction of the cotton strip feeding, thereby realizing the auxiliary operation of cleaning cotton fibers on the fed cotton strip.

[0029] When feeding the tampons, the tampons enter the feeding assembly 4 through the feeding inlet 10, pass through the limiting plate 13, and are limited by the limiting plate 13 to ensure stable feeding of the tampons. The auxiliary seat 14, which is set in a trapezoidal protrusion, supports the fed tampons so that they can be fed through the guide roller 15. During this process, the auxiliary seat 14 delivers airflow from the front end, and the airflow direction is opposite to the feeding direction of the tampons. This blows up the cotton fibers adhering to the tampons. The blown cotton fibers are attracted and collected on the adsorption cylinder 9 by the static electricity generated by the adsorption cylinder 9, thereby achieving a thorough cleaning of the cotton fibers. Subsequently, the tampons enter the detection body for detection and are discharged from the discharge seat 2.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
