Description

Technical Field

[0001] The present invention relates to the technical field of short lint rate detection, and in particular to an anti-interference cotton short lint rate detection device and a detection method thereof. Background Art

[0002] The short lint percentage refers to the percentage of the weight (or number) of short fibers shorter than a certain limit in cotton fibers compared to the total fiber weight (or total number of fibers). The short lint percentage threshold is generally set at 16mm (in China) or 12.5mm (in other countries) for fine-staple cotton, and 20mm for long-staple cotton. Some cotton products require short lint percentage testing to ensure the selection of appropriate raw materials.

[0003] At present, the measurement of cotton lint rate adopts the roller analyzer method specified in the national standard and weighs the samples in groups. The existing weighing method is to place the cotton lint sample between two dividing combs or dividing plates, straighten and disperse the cotton lint through the reciprocating motion of the two dividing combs or dividing plates, and then extract it through the fiber clamp, group it by visual inspection, and then weigh it to obtain the lint rate.

The piston tube is provided with two air inlet pipes, and both the air inlet pipes and the two air outlet pipes are provided with a one-way valve.

[0009] Furthermore, the workbench is slidably mounted with a slide, and the slide passes through the top wall of the workbench. A third electric push rod is provided on the bottom wall of the workbench for pushing the slide to slide, and the sliding directions of the upper and lower dividing plates are perpendicular to each other.

[0010] Furthermore, a discharge plate is provided on the top wall of the lower material dividing plate, a discharge trough is provided on the workbench, and a fourth electric push rod for pushing the discharge plate up and down is slidably installed in the discharge trough.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0020] The present invention will be further described below with reference to the embodiments.

[0021] Example: Reference Figure 1 An anti-interference cotton lint rate detection device includes a workbench 1 and sample lint placed on the workbench 1, and also includes a material separation component for dispersing the sample lint, such as Figure 1 and Figure 2As shown, it includes an upper dividing plate 3 movably installed above the workbench 1, a fixing frame 2 is fixedly installed on the workbench 1, a first electric push rod 6 is fixedly installed on the fixing frame 2, a guide frame 7 is slidably installed on the output shaft at the bottom of the first electric push rod 6, the guide frame 7 is fixedly connected to the top wall of the upper dividing plate 3, a telescopic frame 8 is fixedly installed on the top wall of the upper dividing plate 3, the top of the telescopic frame 8 is slidably installed on the fixing frame 2, and a second electric push rod 9 for pushing the telescopic frame 8 to slide is installed on the fixing frame 2, a diversion cavity is opened in the upper dividing plate 3, and the upper dividing plate 3 is close to the lower A plurality of blowing holes connected to the diversion chamber are provided on one side of the dividing plate 4, a diversion pipe 12 connected to the diversion chamber is provided on the top wall of the upper dividing plate 3, a piston tube 10 is fixedly installed on the fixed frame 2, and a piston rod is movably inserted into the piston tube 10 near one end of the telescopic frame 8, and the piston rod is fixedly connected to the telescopic frame 8, and two air outlet pipes are connected to one side of the piston tube 10, and the two air outlet pipes are commonly connected to the air collecting pipe 11, and the air collecting pipe 11 is connected to the diversion pipe 12, and the piston tube 10 is provided with two air inlet pipes, and both the air inlet pipes and the two air outlet pipes are provided with a one-way valve, such as Figure 3 As shown, a lower dividing plate 4 is slidably installed on the workbench 1, a slide plate 27 is slidably installed on the workbench 1, and the slide plate 27 passes through the top wall of the workbench 1. A third electric push rod 13 is provided on the bottom wall of the workbench 1 for pushing the slide plate 27 to slide, and the sliding directions of the upper dividing plate 3 and the lower dividing plate 4 are perpendicular to each other.

[0022] like Figure 1 and Figure 3 As shown, staggered combs are set on the outer wall of the upper dividing plate 3 and the lower dividing plate 4 on one side. The sample cotton lint is placed on the lower dividing plate 4, and the upper dividing plate 3 is driven downward by the first electric push rod 6. The sample cotton lint is clamped by the combs on the upper dividing plate 3 and the lower dividing plate 4. Figure 2 As shown, the second electric push rod 9 pushes the telescopic frame 8 to drive the upper dividing plate 3 to slide back and forth, and then the third electric push rod 13 is used to drive the slide plate 27 to move, and the lower dividing plate 4 of the slide plate 27 slides back and forth. It is worth noting that the sliding directions of the upper dividing plate 3 and the lower dividing plate 4 are perpendicular to each other, and the upper dividing plate 3 and the lower dividing plate 4 cannot be driven at the same time to prevent collision between the combing of the two.

[0023] In order to prevent the cotton lint fibers from adhering to the upper dividing plate 3 during the process of being straightened and dispersed, a plurality of blowing holes are provided on the bottom wall of the upper dividing plate 3 (i.e., the side containing the combing), and the number of the blowing holes is the same as the number of the combing holes, and corresponds one-to-one with the combing holes. The cotton lint fibers are blown toward the lower dividing plate 4 by the action of the airflow, so that when the upper dividing plate 3 and the lower dividing plate 4 are separated, the cotton lint fibers are always attached to the lower dividing plate 4.

[0024] Specifically, such as Figure 2As shown, during the process in which the second electric push rod 9 drives the telescopic frame 8 to slide back and forth (at this time, the upper dividing plate 3 slides back and forth while the lower dividing plate 4 is stationary), the telescopic frame 8 drives the piston rod to slide back and forth in the piston tube 10. During the process in which the piston rod slides back and forth in the piston tube 10, the air pressure in the piston tube 10 will be changed, as shown in FIG. Figure 2 As shown, there are two air outlet pipes connected between the piston tube 10 and the air collecting pipe 11, and the two air outlet pipes are respectively located on the side wall of one end close to the piston rod and the side wall away from one end of the piston rod, where the positions of the two air inlet pipes correspond to the positions of the two air outlet pipes, and one-way valves are respectively provided in the two air outlet pipes and the two air inlet pipes. Through the action of the one-way valve, the two air outlet pipes will only transport the air in the piston tube 10 to the air collecting pipe 11, and the air inlet pipe will only draw air from the outside. During the sliding process of the piston rod, air always enters the air collecting pipe 11. After entering the air collecting pipe 11, the air enters the diversion pipe 12 and the diversion cavity, and is dispersed to each blowing hole in the diversion cavity, thereby completing the above-mentioned blowing work and ensuring that the cotton lint fiber is always attached to the lower dividing plate 4 to facilitate subsequent detection work.

[0025] refer to Figure 4 A detection component for obtaining the short-lint rate is provided on the workbench 1, which includes a detection frame 15 movably installed above the workbench 1, a fifth electric push rod 16 for driving the detection frame 15 to move is provided on one side of the workbench 1, a plurality of first electrostatic rods 18 are fixedly installed on the bottom wall of the detection frame 15, a plurality of second electrostatic rods 19 are slidably installed on the bottom wall of the detection frame 15, and the first electrostatic rods 18 and the second electrostatic rods 19 are distributed at intervals, a sliding frame 20 is slidably installed on the detection frame 15, the second electrostatic rod 19 is fixedly installed on the sliding frame 20, a sixth electric push rod 21 for driving the sliding frame 20 to slide is provided on the detection frame 15, and two electrostatic generators 24 are provided on the detection frame 15, which absorb the sample cotton lint on the lower dividing plate 4 through the first electrostatic rod 18 and the second electrostatic rod 19, and a discharge plate 5 is provided on the top wall of the lower dividing plate 4, and a discharge trough is provided on the workbench 1, and a discharge trough is slidably installed in the discharge trough There is a fourth electric push rod 14 for pushing the unloading plate 5 up and down, a sliding frame 20 is slidably installed on the detection frame 15, a second electrostatic rod 19 is fixedly installed on the sliding frame 20, and a sixth electric push rod 21 for driving the sliding frame 20 to slide is provided on the detection frame 15, and two electrostatic generators 24 are provided on the detection frame 15. A sliding frame 20 is slidably installed on the detection frame 15, a second electrostatic rod 19 is fixedly installed on the sliding frame 20, and a sixth electric push rod 21 for driving the sliding frame 20 to slide is provided on the detection frame 15, and two electrostatic generators 24 are provided on the detection frame 15. A limiting groove 17 is provided on the bottom wall of the detection frame 15, and a limiting frame 22 is movably installed in the limiting groove 17. A seventh electric push rod 23 for driving the limiting frame 22 to rise and fall is provided on the top wall of the detection frame 15, a material comb 25 is installed on the workbench 1, a collecting tank 26 is provided on the workbench 1, and a weighing device is provided in the collecting tank 26.

[0026] like Figure 1 As shown, the detection frame 15 is driven to slide in the horizontal direction by the fifth electric push rod 16, and its initial position is located directly above the collection tank 26. When detection is required, the detection frame 15 is driven to move directly above the lower dividing plate 4, which is required after the straightening and dividing of the material is completed and the upper dividing plate 3 is moved up and reset.

[0027] Among them, a discharge plate 5 is set on the lower dividing plate 4, such as Figure 3 As shown, the fourth electric push rod 14 is used to control the unloading plate 5 to rise and fall, wherein the unloading plate 5 is provided with holes that are compatible with the combing on the lower dividing plate 4, and the combing on the lower dividing plate 4 is inserted into the holes on the unloading plate 5. After the straightening and dispersion processes are completed, the fourth electric push rod 14 is used to drive the unloading plate 5 to move upward, and the unloading plate 5 lifts the cotton lint fibers above the lower dividing plate 4 and lifts them from the combing gap. This facilitates subsequent inspections, and compared with the method of clamping by a fiber clamp, it can prevent the fibers from being broken, thereby improving the accuracy of subsequent inspections.

[0028] like Figure 4 As shown, the bottom surface of the detection frame 15 is flat, mainly to facilitate the adsorption of cotton lint fibers by the first electrostatic rod 18 and the second electrostatic rod 19. In the process of resetting to the collection tank 26 after adsorption, the bottom surface of the detection frame 15 will be combed by the material comb 25 to move the cotton lint fibers originally adsorbed by a single electrostatic rod, so that the middle section is moved to a state where both ends are adsorbed by the first electrostatic rod 18 and the second electrostatic rod 19 respectively.

[0029] Then, the detection rack 15 is reset to the position just above the collecting tank 26. Figure 7 As shown, the seventh electric push rod 23 is used to pull the limit frame 22 upward. At this time, the bottom wall of the detection frame 15 is no longer flat, and the second electrostatic rods 19 are no longer limited. Then the sixth electric push rod 21 is started to drive the sliding frame 20 to slide, driving all the second electrostatic rods 19 away from the first electrostatic rods 18 that were originally attached (as shown in FIG. Figure 6 As shown), and as Figure 8 As shown, in the process of the second electrostatic rod 19 moving away from the corresponding first electrostatic rod 18, the first electrostatic rod 18 and the second electrostatic rod 19 respectively adsorb the two ends of the fiber, and the second electrostatic rod 19 pulls the fiber to move through the adsorption force. While straightening the fiber, unqualified fibers will also break away from one of the electrostatic rods until the moving distance of the second electrostatic rod 19 meets the minimum fiber qualified length requirement and stops.

[0030] Finally, the electrostatic generator 24 connected to the first electrostatic rod 18 is turned off. The qualified fibers adsorbed by the first electrostatic rod 18 will not fall because their other ends are adsorbed by the second electrostatic rod 19. The unqualified fibers originally adsorbed by the first electrostatic rod 18 lose their adsorption and fall because their other ends lack additional adsorption force. After a period of quiescence (allowing the fibers to fall), the electrostatic generator 24 connected to the first electrostatic rod 18 is restarted, and the electrostatic generator 24 connected to the second electrostatic rod 19 is turned off. This is similar to the cleaning of unqualified fibers adsorbed by the first electrostatic rod 18. After a period of quiescence, the unqualified fibers (short lint) collected in the collection tank 26 are weighed and compared with the overall weight of the cotton lint sample to obtain the short lint rate.

[0031] like Figure 4 As shown, two electrostatic generators 24 are used to control the first electrostatic rod 18 and the second electrostatic rod 19 to be attached with static electricity, and the cotton fibers on the lower dividing plate 4 are picked up by the electrostatic adsorption force. Due to the provision of the discharge plate 5, the cotton fibers are lifted from the combing gap, which makes it easier for the first electrostatic rod 18 and the second electrostatic rod 19 to attract the cotton fibers.

[0032] The electrostatic generator 24 is a conventional device that primarily generates static electricity. The output is typically single-polarity, such as positive or negative, and the output voltage is adjustable. Applications of electrostatics include electrostatic dust removal, electrostatic spraying, and generating electrostatic fields. Furthermore, the electrostatic attraction of fibrous objects is greater at the ends than in the middle.

[0033] A detection method for an interference-resistant cotton lint rate detection device comprises the following steps: S1: Weigh the cotton lint sample, place the cotton lint sample on the lower dividing plate 4, drive the upper dividing plate 3 to move downward to clamp the cotton lint sample between the upper dividing plate 3 and the dividing plate 4, and disperse the cotton lint sample by sliding the upper dividing plate 3 and the lower dividing plate 4. After dispersion is completed, drive the upper dividing plate 3 to move upward and reset; S2: Drive the detection frame 15 to the top of the lower dividing plate 3, use the first electrostatic rod 18 and the second electrostatic rod 19 to absorb the scattered cotton lint sample, and move it back to the original position after the absorption is completed. During the reset process, use the material comb 25 to move the cotton lint sample so that a single cotton lint sample is simultaneously absorbed by the first electrostatic rod 18 and the second electrostatic rod 19, and then returns to the top of the collection tank 26; S3: Drive the sliding frame 20 to slide, driving the second electrostatic rod 19 to gradually move away from the first electrostatic rod 18. The moving distance is the length of the qualified cotton lint, so that only one end of the unqualified cotton lint is adsorbed by one of the electrostatic rods. First, disconnect the electrostatic generator 24 of the first electrostatic rod 18 and the second electrostatic rod 19, and then start the electrostatic rod that was originally disconnected, and disconnect the electrostatic rod that was originally started. By disconnecting and switching, the unqualified cotton lint falls into the collection tank 26, and the mass of the unqualified cotton lint is obtained, and the short lint rate is obtained through the mass ratio.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
