Description

Technical Field

[0001] This utility model relates to the field of foreign fiber detection technology, specifically a foreign fiber detection device for textiles. Background Technology

[0002] Foreign fibers, also known as non-cotton fibers, originate from the cotton harvesting process and refer to non-cotton and non-natural cotton fibers mixed in with cotton, such as chemical fibers and hair, which have a serious impact on the quality of cotton and its products. During the processing of cotton-based textiles, these fibers are easily crushed, broken, and diffused within the cotton fibers, ultimately dispersing in the yarn or on the fabric surface, forming defects. Therefore, foreign fiber detection devices are needed to detect foreign fibers during the textile process.

[0003] For example, Chinese patent application number CN201220033611.2 describes a device for detecting and removing foreign fibers on a textile winding machine. It employs a photoelectric and capacitive combined sensor array to simultaneously acquire reflection, transmission, and density data signals from the yarn. The combined reflection, transmission, and density data signal is detected and identified digitally by a microcontroller unit (MCU), thus distinguishing white fibers from other colors for removal. It boasts a high foreign fiber detection rate and a low false-cut rate, achieving a resolution of 1 mm at a line speed of 2000 m / min.

[0004] However, in actual use, the above-mentioned device can only detect foreign fibers in textiles using a green modulated light source. It is affected by ambient light and has difficulty penetrating dark or complex textured fabrics to detect foreign fibers inside the textiles, thus reducing the detection accuracy and effectiveness. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a foreign fiber detection device for textiles. By adjusting the distance between the isolation plate and the top of textiles of different thicknesses, visible light LED beads and external LED strips operate in a time-sharing manner, switching between each other. A high-resolution CCD camera captures high-definition images to detect foreign fibers in textiles conveyed on the top of the conveyor. This enables the detection of foreign fibers in dark-colored textiles or fabrics with complex textures, ensuring detection effectiveness, expanding applicability, and effectively solving the problems in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a foreign fiber detection device for textiles, comprising a U-shaped frame and a conveyor fixedly installed at the top of the inside of the U-shaped frame;

[0007] A detection component is fixedly installed on one side of the top of the U-shaped frame for in-depth detection of foreign fibers in textiles of different colors.

[0008] A support plate is fixedly provided on the other side of the top of the U-shaped frame, and a sorting component is provided on the support plate for sorting out the detected foreign fibers;

[0009] The detection component includes a trapezoidal fixed frame, which is fixedly mounted on one side of the top of a U-shaped frame. A high-resolution CCD camera is fixedly mounted at the top inside the trapezoidal fixed frame, and an anti-glare glass cover is fixedly mounted at the bottom of the high-resolution CCD camera. Fixing plates are fixedly mounted on both sides of the bottom of the trapezoidal fixed frame, and several evenly distributed infrared LED light strips are fixedly mounted on the bottom of the fixing plates. Several evenly distributed visible light LED beads are fixedly mounted on both sides of the inner side walls of the trapezoidal fixed frame.

[0010] Preferably, infrared sensors are fixedly installed on both sides of the top of the inner trapezoidal fixed frame, and two infrared sensors are respectively located on both sides of the trapezoidal fixed frame. The two fixed plates are fixed between the front and rear sides of the top of the U-shaped frame, which facilitates the detection of foreign fibers in dark-colored and complex-patterned textiles.

[0011] Preferably, a partition plate is provided through one end of the fixed plate on the side away from the support plate. The partition plate has a plurality of evenly distributed threaded holes on the side away from the fixed plate. The fixed plate on the side away from the support plate is connected by a bolt for fixing the partition plate and the fixed plate by a thread, and the threaded holes and bolts are matched to each other, so as to facilitate the adjustment of the distance between the fixed plate and the textiles at the top of the conveyor.

[0012] Preferably, the sorting assembly includes a blower, which is fixedly mounted on the top of the support plate. The blower nozzle is fixedly provided with an air pipe, and an electric valve is fixedly mounted on the air pipe. The electric valve is located on the top of the support plate. The bottom end of the air pipe passes through the support plate and is fixedly provided with a jet pipe. Several inclined nozzles are fixedly mounted on the jet pipe to facilitate directional spraying at a reverse tilt angle. By utilizing the combined effect of airflow backlash and the inertia of the conveyor's movement direction, foreign fibers are ejected from the surface of the textile.

[0013] Preferably, the sorting assembly further includes an air suction machine, which is fixedly installed on the other side of the U-shaped frame. The air suction port of the air suction machine is fixedly provided with two U-shaped connecting pipes, which are respectively installed on the front and rear sides of the U-shaped frame. A collection inclined frame is fixedly provided on the bottom of the support plate near the trapezoidal fixed frame, so that the foreign fibers blown away can be absorbed in time through the collection inclined frame.

[0014] Preferably, the top ends of the two U-shaped connecting pipes pass through the front and rear sides of the U-shaped frame and are fixedly connected to the front and rear sides of the collecting inclined frame. A filter screen is fixedly installed inside the top end of the U-shaped connecting pipe and is located inside the collecting inclined frame. The nozzle and the bottom end of the collecting inclined frame are flush with each other, so that after the foreign fibers are blown out by the nozzle, they can be absorbed by the collecting inclined frame in time.

[0015] Preferably, the support plate is hinged to a top cover on the side near the trapezoidal fixed frame. The front side of the U-shaped frame is fixed with a control panel for controlling the operation of the conveyor, trapezoidal fixed frame, visible light LED beads, infrared LED strip, infrared sensor, blower, electric valve and suction machine.

[0017] This invention adjusts the distance between the isolation plate and the top of textiles of different thicknesses, allowing the conveyor to transport the textiles into the bottom of the trapezoidal fixed frame. Visible light LED beads and external LED strips work in a time-sharing manner, switching between each other, and a high-resolution CCD camera captures high-definition images to detect foreign fibers in the textiles. This enables the detection of foreign fibers in dark-colored textiles or complex textured fabrics, ensuring detection effectiveness and expanding the scope of application.

Detailed Implementation

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-6 As shown, this utility model provides a foreign fiber detection device for textiles, including a U-shaped frame 1 and a conveyor 2 fixedly installed at the top of the U-shaped frame 1. A support plate 8 is fixedly installed on the other side of the top of the U-shaped frame 1, and support piles 6 are fixedly installed on both sides of the bottom of the U-shaped frame 1 to facilitate support of this utility model.

[0028] like Figure 1-4 As shown, a detection component 3 is fixedly installed on one side of the top of the U-shaped frame 1 for deep detection of foreign fibers in textiles of different colors. The detection component 3 includes a trapezoidal fixed frame 31, which is fixedly installed on one side of the top of the U-shaped frame 1. A high-resolution CCD camera 32 is fixedly installed at the top inside the trapezoidal fixed frame 31. An anti-glare glass cover 33 is fixedly installed at the bottom of the high-resolution CCD camera 32. Fixing plates 35 are fixedly installed on both sides of the bottom of the trapezoidal fixed frame 31. Several evenly distributed infrared LED light strips 36 are fixedly installed at the bottom of the fixing plates 35. Several evenly distributed visible light LED beads 34 are fixedly installed on both sides of the inner side walls of the trapezoidal fixed frame 31. Infrared sensors are fixedly installed on both sides of the top of the trapezoidal fixed frame 31, and two infrared sensors are respectively installed on both sides of the trapezoidal fixed frame 31. The two fixing plates 35 are fixed between the front and rear sides of the top of the U-shaped frame 1, which facilitates the detection of foreign fibers in dark-colored and complex-patterned textiles.

[0029] A partition plate 37 is provided through one end of the fixing plate 35 on the side away from the support plate 8. The partition plate 37 has several evenly distributed threaded holes 38 on the side away from the fixing plate 35. The fixing plate 35 on the side away from the support plate 8 is connected by a bolt 39 for fixing the partition plate 37 and the fixing plate 35 through a thread. The threaded holes 38 and the bolt 39 are matched to each other, which facilitates the adjustment of the distance between the fixing plate 35 and the top textile of the conveyor 2. The support plate 8 is hinged to a top cover 9 on the side near the trapezoidal fixing frame 31. A control panel 5 is fixed on the front side of the U-shaped frame 1 for controlling the operation of the conveyor 2, the trapezoidal fixing frame 31, the visible light LED beads 34, the infrared LED light strip 36, and the infrared sensor.

[0030] By setting the detection component 3, the textile to be detected is placed on the surface of the conveyor 2 inside the U-shaped frame 1. Depending on the thickness of the textile, the bolt 39 is loosened, and the isolation plate 37 is lifted and lowered along the fixed plate 35. After shortening the distance between the isolation plate 37 and the top of the textile, the bolt 39 is tightened through the threaded hole 38 to fix the position of the isolation plate 37. Then, the control panel 5 is operated to control the conveyor 2 to work. The conveyor 2 transports the textile into the bottom of the trapezoidal fixed frame 31. The visible light LED beads 34 and the outer LED light strip 36 work in turn and are switched through the control panel 5 to avoid spectral crosstalk. The visible light LED beads 34 and the infrared LED light strip 36 work synchronously and are tilted from top to bottom to highlight the texture and color difference of the surface fibers. The high-resolution CCD camera 32 captures high-definition images.

[0031] Meanwhile, the infrared LED light strip 36 penetrates the textile vertically from top to bottom. The symmetrically arranged infrared sensors receive the deep signals and identify foreign objects embedded inside transparent or dark textiles. Finally, the control panel 5 uses a deep learning algorithm to fuse visible light images and infrared thermal radiation data in real time, thereby enabling the detection of foreign fibers in dark textiles or complex textured fabrics, ensuring detection effectiveness and improving the applicability.

[0032] like Figure 1-3 As shown in Figures 5 and 6, the support plate 8 is provided with a sorting assembly 4 for sorting out the detected foreign fibers. The sorting assembly 4 includes a blower 41, which is fixedly mounted on the top of the support plate 8. An air pipe 42 is fixedly mounted on the air outlet of the blower 41. An electric valve 43 is fixedly mounted on the air pipe 42, which is located on the top of the support plate 8. The bottom end of the air pipe 42 passes through the support plate 8 and is fixedly mounted with a jet pipe 44. Several inclined nozzles 45 are fixedly mounted on the jet pipe 44 to facilitate directional spraying at a reverse tilt angle through the nozzles 45. The foreign fibers are bounced off the surface of the textile by the combined effect of the airflow backlash and the inertia of the conveyor 2.

[0033] The sorting assembly 4 also includes an air suction machine 46, which is fixedly mounted on the other side of the U-shaped frame 1. The air suction machine 46 has two U-shaped connecting pipes 47 fixedly mounted at its air intake. The two U-shaped connecting pipes 47 are respectively located on the front and rear sides of the U-shaped frame 1. A collection inclined frame 48 is fixedly mounted on the bottom of the support plate 8 near the trapezoidal fixed frame 31, so that the foreign fibers blown away can be absorbed in time through the collection inclined frame 48. The top ends of the two U-shaped connecting pipes 47 pass through the front and rear sides of the U-shaped frame 1 and are fixedly connected to the front and rear sides of the collection inclined frame 48.

[0034] The filter screen 49 is fixedly installed inside the top end of the U-shaped connecting pipe 47 and is located inside the collecting inclined frame 48. The nozzle 45 and the bottom end of the collecting inclined frame 48 are flush with each other, so that after the foreign fiber is blown out by the nozzle 45, it can be absorbed by the collecting inclined frame 48 in time. The blower 41, electric valve 43 and suction machine 46 are all controlled by the control panel 5.

[0035] By setting up the sorting component 4, after the foreign fiber detection is completed, the encoder built into the conveyor 2 provides real-time feedback on the linear velocity of the textile movement. Combined with the detected foreign fiber coordinate data, the control panel 5 accurately determines the time point when the foreign fiber arrives directly below several nozzles 45. When the foreign fiber enters the effective range of the nozzles 45, the control panel 5 controls the electric valve 43 to open, causing the blower 41 to blow air into the air pipe 42 and then onto the textile surface through several nozzles 45. At the same time, due to the tilted reverse angle of the nozzles 45, the air jet is directed and sprayed. The air jet is combined with the inertia of the airflow backlash and the direction of movement of the conveyor 2 to bounce the foreign fiber away from the textile surface. Simultaneously, the suction machine 46 is controlled to work. The suction machine 46 absorbs and collects the gas and floating foreign fibers inside the inclined frame 48 through two U-shaped connecting pipes 47. The foreign fibers enter the collection inclined frame 48 and are adsorbed onto the filter screen 49 through the U-shaped connecting pipes 47. Finally, by opening the top cover 9, the foreign fibers can be centrally cleaned, thus ensuring the foreign fiber removal effect and maximizing the integrity of the textile.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
