Description

Technical Field

[0001] This application relates to the field of textile industrial machinery, and particularly to a foreign fiber separator with multi-channel detection. Background Art

[0002] With the upgrading of the industry and the development of the market, consumers' requirements for the quality of textile products are increasing day by day. And the content of foreign fibers in the textile raw material cotton is an important factor affecting the quality of textiles and printing and dyeing quality. Therefore, foreign fiber separators are generally introduced in the pre-spinning production to remove foreign fibers in cotton to improve product quality.

[0003] In the actual application process, new problems will also arise in the foreign fiber removal of the foreign fiber separator: First, the foreign fiber separator generally detects foreign fibers in cotton through image recognition (relying on light sources, detection cameras, algorithms, etc.). The detection means of a single foreign fiber separator are relatively single, and the actual effect of impurity removal is limited. Second, in order to better remove impurities, in the pre-spinning production, generally, the sensitivity parameter of the foreign fiber separator detection is increased, or multiple foreign fiber separators are connected in series to increase the foreign fiber ejection rate. Under the above methods, while the foreign fiber separator discharges waste cotton, it also inevitably brings out more cotton, causing greater waste and economic losses. If manual cotton picking is used, it will take up man-hours and increase labor costs. At the same time, connecting multiple foreign fiber separators in series also requires a large workshop space and consumes more electric energy. The longer and more curved cotton flow channel formed by connecting the foreign fiber separators in series will also cause more cotton knots in the cotton (for each additional bend the cotton experiences, the number of cotton knots increases by about 15%), affecting the quality of the cloth. Content of the Utility Model

[0004] In order to solve the problems raised in the background art, based on the production characteristics of the foreign fiber separator, this application provides a foreign fiber separator with multi-channel detection to improve the detection rate of foreign fibers and be able to re-open and remove impurities from the foreign fiber-containing cotton discharged from the detection for recycling.

Detailed implementation manners

[0024] The following further Figures 1-4 describes the present application in detail.

[0025] The embodiment of the present application discloses a foreign fiber machine with multi-channel detection.

[0026] Referring to Figure 1 , Figure 2 and Figure 3 , a foreign fiber machine with multi-channel detection includes a body 1 and a cotton flow channel 2, a foreign fiber detection module 3, a waste cotton knocking-out module 4, a waste cotton collection module 5, an opening module 6, and a recycled cotton collection module 7 provided on the body 1; wherein, the cotton flow channel 2 penetrates the body 1 from bottom to top, the cotton to be detected enters the body 1 from the inlet of the cotton flow channel 2 and continuously flows in the cotton flow channel 2, the foreign fiber detection module 3 is used for real-time detection of foreign fibers in the cotton to be detected, the waste cotton knocking-out module 4 is used for knocking out the waste cotton-containing cotton (a small part of cotton containing foreign fibers) in the cotton to be detected in the cotton flow channel 2, the waste cotton collection module 5 is used for receiving the waste cotton-containing cotton knocked out in the cotton flow channel 2 and conveying the first knocked-out waste cotton-containing cotton to the opening module 6, and the opening module 6 is used for opening the first knocked-out waste cotton-containing cotton and re-inputting the opened waste cotton-containing cotton into the cotton flow channel 2 for secondary detection processing of the waste cotton-containing cotton, and the recycled cotton collection module 7 is used for collecting the recycled cotton obtained from the secondary detection processing.

[0027] Specifically, referring to Figure 2 and Figure 3 , the foreign fiber detection module 3 includes a composite light source group, an industrial camera 31, an image recognition and processing module, and an AI module. A detection box for installing the foreign fiber detection module 3 is fixedly provided on the body 1, and the opening of the detection box is communicated with the cotton flow channel 2.

[0028] In the preferred solution of the embodiment of the present application, the opening of the cotton flow channel 2 is rectangular, and the long side of the opening of the cotton flow channel 2 is horizontally arranged. The multi-channel foreign fiber detector in the present application uses a single cotton flow channel 2 to convey cotton flow. The number of bends in the cotton flow channel 2 is much less than that in the case of multiple foreign fiber detectors connected in series, which is beneficial to reducing cotton knots and facilitating the composite light source group and the foreign cotton ejection module 4 to better detect and remove foreign fibers. The composite light source group and the industrial camera 31 are both provided with three groups, and the detection box is provided with three places. Each group of composite light source groups corresponds to the industrial camera 31 one by one, and the corresponding composite light source group and the industrial camera 31 are installed in the same detection box. Each group of composite light source groups includes two light source units with the same specifications. Each light source unit is composed of a light bar and a light rack. The light source unit is strip-shaped, and the long side of the light source unit is parallel to the long side of the opening of the cotton flow channel 2 to maximize the effective irradiation of the cotton flow channel 2 and facilitate the accurate and stable imaging of foreign fibers. Along the direction of conveying cotton flow in the cotton flow channel 2, a foreign cotton inlet 21, a foreign cotton outlet, and a recycled cotton outlet 22 are sequentially arranged on the cotton flow channel 2. The three groups of composite light source groups are sequentially arranged on both sides of the cotton flow channel 2 along the direction of conveying cotton flow in the cotton flow channel 2 to realize the double-sided detection of the cotton to be detected in the cotton flow channel 2 and improve the detection rate of foreign fibers.

[0029] In other feasible solutions of the embodiment of the present application, the composite light source group can also be set to two groups or more than three groups. When the composite light source group is set to two groups, it can only realize the single-sided and double-sided detection of the cotton to be detected or the two-sided and three-sided detection of the cotton to be detected. The ability of the two groups of composite light source groups to detect foreign fibers is lower than that of the three groups of composite light source groups. When the composite light source group is set to more than three groups, there are more combination methods for multiple groups of composite light source groups, and the detection ability is slightly higher than that of the three groups of composite light source groups. However, the composite light source group occupies more equipment space, and the overall floor space and cost of the equipment are relatively high, which is not conducive to the wide promotion of the equipment.

[0030] Correspondingly, there are two foreign cotton outlets.

[0031] Refer to Figure 2 and Figure 3, in the embodiments of the present application, along the direction of conveying the cotton flow in the cotton flow channel 2, the two waste cotton outlets are respectively named waste cotton outlet A23 and waste cotton outlet B24, the three groups of composite light source groups are respectively named composite light source group A32, composite light source group B33 and composite light source group C34, and the three detection boxes are respectively named detection box one 11, detection box two 12 and detection box three 13; Detection box one 11 is between the waste cotton inlet 21 and waste cotton outlet A23. The composite light source group A32 and the corresponding industrial camera 31 are both installed in detection box one 11. Detection box two 12 and detection box three 13 are located between waste cotton outlet A23 and waste cotton outlet B24. Moreover, detection box one 11 and detection box two 12 are located on the upper side of the cotton flow channel 2, and detection box three 13 is located on the lower side of the cotton flow channel 2. The composite light source group B33 and the corresponding industrial camera 31 are both installed in detection box two 12, and the composite light source group C34 and the corresponding industrial camera 31 are both installed in detection box three 13.

[0032] The waste cotton knocking-out module 4 correspondingly includes two groups of spray valve groups arranged in sequence along the cotton flow channel 2. The spray valve groups are oppositely arranged on both sides of the cotton flow channel 2 corresponding to the waste cotton outlets one by one, and the two groups of spray valve groups are respectively arranged facing waste cotton outlet A23 and waste cotton outlet B24.

[0033] The cotton flow to be detected enters the foreign fiber separator from the inlet of the cotton flow channel 2 and is first detected by detection box one 11. The waste cotton-containing cotton is knocked out from waste cotton outlet A23 via the spray valve group; The main cotton flow continues to be detected by detection box two 12 and detection box three 13 on both sides. The waste cotton-containing cotton is knocked out from waste cotton outlet B24 via the spray valve group, so that the waste cotton-containing cotton is knocked out twice, realizing the first single-sided and double-sided detection of the cotton flow to be detected.

[0034] The waste cotton-containing cotton knocked out twice enters the waste cotton collection module 5 and is conveyed to the opening module 6 for opening.

[0035] Specifically, referring to Figure 3 and Figure 4 , the waste cotton collection module 5 includes a waste cotton collection component 51 and a waste cotton collection component 52. The opening module 6 is a small opening machine in the embodiments of the present application, and the opening module 6 is suitable for opening cotton.

[0036] Looking back Figure 1 and referring to Figure 3 , the waste cotton collection component 51 includes a waste cotton channel 511 and a waste cotton collection fan 512.

[0037] There are two waste cotton channels 511, which are respectively named waste cotton channel 511 one and waste cotton channel 511 two. The inlet end of waste cotton channel 511 one is connected to waste cotton outlet A23, and the inlet end of waste cotton channel 511 two is connected to waste cotton outlet B24. The outlet ends of waste cotton channel 511 one and waste cotton channel 511 two are connected to the inlet end of the opening and loosening module 6 through a tee pipe; the waste cotton collecting fan 512 is installed at the tee pipe. The waste cotton with impurities ejected twice converges through waste cotton channel 511 one and waste cotton channel 511 two, and is transported to the inlet of the small cotton opener by the tee pipe and the waste cotton collecting fan 512.

[0038] Further, the outlet of the small cotton opener is connected to the waste cotton inlet 21.

[0039] The waste cotton collecting component 52 includes a waste cotton channel 521, a waste cotton collecting fan 522 and a waste cotton collecting tray 523. The waste cotton collecting tray 523 is provided with a waste cotton inlet and a waste cotton outlet. The inlet end of the waste cotton channel 521 is connected to the waste cotton channel 511, and the outlet end is connected to the waste cotton inlet. The waste cotton collecting fan 522 is installed on the waste cotton channel.

[0040] Refer to Figure 1 and Figure 3 The recycled cotton collecting module 7 includes a recycled cotton channel 71, a recycled cotton collecting fan 72 and a recycled cotton collecting tray 73. The recycled cotton collecting tray 73 is provided with a recycled cotton inlet and a recycled cotton outlet 22. The inlet end of the recycled cotton channel 71 is connected to the recycled cotton outlet 22, and the outlet end is connected to the recycled cotton inlet. The recycled cotton collecting fan 72 is installed on the recycled cotton channel 71.

[0041] After the waste cotton with impurities is opened and loosened by the small cotton opener, the cotton flow enters the cotton flow channel 2 again through the waste cotton inlet 21, and is detected on one side by the detection box one 11, and detected on both sides by the detection box two 12 and the detection box three 13. The waste cotton with impurities in the cotton flow is ejected again from the waste cotton outlet A23 and the waste cotton outlet B24 by the spray valve group, and the waste cotton with impurities ejected this time is high-impurity waste cotton.

[0042] The high-impurity waste cotton passes through the waste cotton channel 521 and is sent into the waste cotton collecting tray 523 by the waste cotton collecting fan 522, so as to realize the collection of waste cotton.

[0043] After the waste cotton with impurities is detected and decontaminated twice, relatively clean recycled cotton is obtained. The recycled cotton passes through the recycled cotton channel 71 and the recycled cotton collecting fan 72, and is sent into the recycled cotton collecting tray 73. (The recycled cotton can be directly transported to the main cotton flow after passing the inspection according to the quality requirements of textiles, and enter the next textile process)

[0044] The implementation principle of a foreign fiber detector with multi-channel detection in an embodiment of this application is as follows: When removing foreign fibers from the cotton to be inspected, the cotton flow to be inspected enters the multi-channel detection foreign fiber detector in this application through the entrance of the cotton flow channel 2, and single-sided detection is achieved through the first detection box 11, and double-sided detection is achieved through the second detection box 12 and the third detection box 13. The first ejection of the cotton containing impurities is achieved through the spray valve group; after the first ejection, the cotton containing impurities is processed by the cotton containing impurities collection component 51 and the small cotton opener, and then returns to the cotton flow channel 2 again, and single-sided detection is achieved through the first detection box 11 again, and double-sided detection is achieved through the second detection box 12 and the third detection box 13 to achieve the second ejection of the cotton containing impurities, thereby effectively improving the detection rate of foreign fibers and the impurity removal rate of the main cotton. At the same time, the multi-channel detection foreign fiber detector in this application can also re-open and remove impurities from the detected cotton containing impurities for recycling, effectively reducing the waste of cotton.
