Description

Technical Field

[0001] The invention belongs to the technical field of fabric width detection, and in particular relates to a wrinkle-resistant high-elastic composite textile fabric width detection device. Background Art

[0002] In the textile industry chain, after textile fabrics enter processing enterprises such as garment factories and home textile factories, in order to avoid problems such as cutting waste and non-compliant size of finished products in subsequent processing, the width of the fabrics needs to be strictly tested before being put into use. Due to the variety of textile fabrics, for example, jacquard textile fabrics and wrinkle-resistant and high-elastic composite textile fabrics, these types of fabrics usually require the use of width detection equipment during the production process. Existing detection equipment such as announcement number: CN218646255U discloses a width detection device for jacquard textile fabrics.

[0003] There are many types of width detection equipment available. Taking optical detection equipment as an example, due to the wide variety of widths of wrinkle-resistant and highly elastic composite textile fabrics on the market, the common ones are 36 inches, 44 inches, 56-60 inches, etc., it is difficult for width detection equipment to accurately adjust and measure according to different types of fabrics. As a result, during the detection process, measurement errors are prone to occur due to inaccurate matching of the equipment and the fabric width, and the actual width of the fabric cannot be accurately reflected. In addition, during the production, transportation, and storage of wrinkle-resistant and highly elastic composite textile fabrics, the surface will inevitably be contaminated with dust and impurities. These dust and impurities are likely to be blown up during the transportation process, which will interfere with the light propagation and reflection of the detection equipment, seriously affecting the accuracy and reliability of the measurement, and thus obtaining width data with large deviations.

[0004] Therefore, a width detection device for wrinkle-resistant and high-elastic composite textile fabrics is proposed. Summary of the invention

Through the provided marking mechanism, the two sets of coating pipes and coating nozzles of the marking mechanism can be independently opened according to the detection results of the widths of both sides of the fabric. When the fabric width is detected to be abnormal, the PLC controller controls the second electromagnetic switching valve to open, so that the erasable coating drops on the abnormal part, facilitating subsequent quick identification and processing by the staff, and improving the convenience and efficiency of production and processing.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0020] As shown Figures 1 - 6 in the figure, a width detection device for an anti-wrinkle and highly elastic composite textile fabric includes a detection table 1, and a feed guiding roller 2 and a discharge guiding roller 3 arranged on both sides of the top of the detection table 1. Two limiting discs 14 are symmetrically and slidably arranged on the roller wall of the feed guiding roller 2. Fixed rings 15 are fixedly arranged on the side walls of the two limiting discs 14. Springs 16 are arranged between the two fixed rings 15 and the limiting discs 14, and the springs 16 are sleeved on the roller wall of the feed guiding roller 2. When fabrics with different widths pass through the feed guiding roller 2, the acting forces of the two sides of the fabric on the limiting discs 14 are different, resulting in different compression degrees of the springs 16. At the same time, the two limiting discs 14 that can be expanded and contracted based on the elasticity of the springs 16 will exert a reverse acting force on the fabric to ensure that the fabric can accurately pass through the inside of the detection box 4. It also includes: The detection box 4 is fixedly arranged on the top of the detection table 1. A feed inlet 5 and a discharge outlet 6 are respectively arranged on both sides of the detection box 4. A sealing door panel 7 is arranged on the top of the detection box 4. The sealing door panel 7 is hinged to the top of the detection box 4, and a sealing ring is arranged between the sealing door panel 7 and the detection box 4 to improve the sealing performance. Light-shielding curtains are fixedly arranged inside the feed inlet 5 and the discharge outlet 6. When the fabric is conveyed through the inside of the detection box 4, the light-shielding curtains can reduce the external light from entering the inside of the detection box 4, reduce the interference of external light, ensure the measurement accuracy, and reduce errors.

[0021] The dust detection mechanism 8 is arranged on the side wall of the detection box 4 and is used to detect the dust on the surface of the fabric. The dust detection mechanism 8 includes mounting plates 81 fixedly arranged on the side wall of the detection box 4. The number of the mounting plates 81 is four, and they are symmetrically distributed in pairs above and below the feed inlet 5. Dust sensors 82 are fixedly arranged on the surfaces of the four mounting plates 81. The four dust sensors 82 synchronously detect the dust on the upper and lower surfaces of the fabric.

[0022] Cleaning mechanism 9 is arranged between the side wall of the detection box 4 and the side wall of the detection table 1, and is used for cleaning the dust and impurities on the upper and lower surfaces of the fabric. The cleaning mechanism 9 includes a dust collector 91 fixedly arranged on the side wall of the detection table 1. Above the feeding port 5 on the side wall of the detection box 4, there is an upper hollow plate 92. A upper cleaning brush 93 is fixedly arranged on the lower surface of the upper hollow plate 92. A first cylinder 94 is fixedly arranged on the upper surface of the upper hollow plate 92, and the base of the first cylinder 94 is fixedly connected to the side wall of the detection box 4. On the side wall of the detection box 4 and below the feeding port 5, there is a lower hollow plate 95 fixedly arranged. A lower cleaning brush 96 is fixedly arranged on the upper surface of the lower hollow plate 95. The suction end of the dust collector 91 is fixedly provided with a first rubber suction pipe 97. The end of the first rubber suction pipe 97 is fixedly connected to the side wall of the upper hollow plate 92. A second rubber suction pipe 98 is fixedly arranged on the pipe wall of the first rubber suction pipe 97, and the end of the second rubber suction pipe 98 is fixedly connected to the side wall of the lower hollow plate 95. A third rubber suction pipe 99 is fixedly arranged on the pipe wall of the first rubber suction pipe 97, and the end of the third rubber suction pipe 99 extends into the interior of the detection box 4. A first electromagnetic switch valve 910 is arranged between the second rubber suction pipe 98 and the third rubber suction pipe 99 on the pipe wall of the first rubber suction pipe 97. When the dust collector 91 and the first cylinder 94 are started and the first electromagnetic switch valve 910 is opened, when the dust collector 91 operates, a negative pressure environment is formed in the first rubber suction pipe 97, the second rubber suction pipe 98, the upper hollow plate 92 and the lower hollow plate 95. Under the action of the negative pressure, the dust on the upper and lower surfaces of the fabric is sucked. At the same time, the first cylinder 94 extends, driving the upper hollow plate 92 to move downward, so that the upper cleaning brush 93 is in close contact with the upper surface of the fabric, and then cooperating with the lower cleaning brush 96 to contact the lower surface of the fabric, the upper and lower surfaces of the moving fabric are cleaned.

[0023] Two optical width detection mechanisms 10 are symmetrically arranged on the inner side walls of both sides of the detection box 4 and are used for detecting both sides of the fabric. The optical width detection mechanism 10 includes a second cylinder 101 fixedly arranged on the inner side wall of the detection box 4. A U-shaped plate 102 is fixedly arranged at the moving end of the second cylinder 101. A third cylinder 103 is fixedly arranged at the top of the U-shaped plate 102. A laser emitter 104 is fixedly arranged at the moving end of the third cylinder 103. A laser receiver 105 is fixedly arranged at the bottom of the U-shaped plate 102. The laser beam emitted by the laser emitter 104 can be exactly received by the laser receiver 105. During the telescopic process of the second cylinder 101, it drives the U-shaped plate 102 to perform a lateral displacement, so that the laser emitter 104 and the laser receiver 105 installed on the U-shaped plate 102 move synchronously. The telescopic movement of the third cylinder 103 can drive the laser receiver 105 to move upward or downward, and can adjust the distance between the laser emitter 104 and the laser receiver 105.

[0024] The electric signal regulating mechanism 11 is arranged on the inner bottom wall of the detection box 4, and the electric signal regulating mechanism 11 is connected to the two optical width detection mechanisms 10. The electric signal regulating mechanism 11 includes a measurement box 111 fixedly arranged on the inner bottom wall of the detection box 4. A resistance rod 112 is fixedly arranged inside the measurement box 111. Two conductive sleeves 113 are symmetrically and slidably arranged on the rod wall of the resistance rod 112. Sliders 114 are fixedly arranged outside the two conductive sleeves 113. The two sliders 114 are both slidably arranged inside the measurement box 111. Connecting columns 115 are fixedly arranged on the tops of the two sliders 114. The upper ends of the two connecting columns 115 are respectively fixedly connected to the bottoms of the two U-shaped plates 102. When the U-shaped plate 102 moves, the bottom of the U-shaped plate 102 drives the slider 114 to slide inside the measurement box 111 through the connecting column 115. At the same time, the two conductive sleeves 113 connected to the slider 114 move synchronously on the resistance rod 112 until the electric signal generated by the resistance value of the resistance rod 112 connected to the circuit completely matches the pre-recorded signal value of the fabric width.

[0025] The marking mechanism 12 is arranged on the inner top wall of the detection box 4 and is used to mark the abnormal parts of the fabric width. The marking mechanism 12 includes a paint storage box 121 fixedly arranged on the top of the detection box 4. Two paint pipes 122 are symmetrically and fixedly arranged at the bottom of the paint storage box 121. The lower ends of the two paint pipes 122 both extend into the detection box 4, and paint nozzles 123 are fixedly arranged at the lower ends of the two paint pipes 122. Second electromagnetic switching valves 124 are fixedly arranged at the lower ends of the pipe walls of the two paint pipes 122. By controlling the second electromagnetic switching valve 124 to open, the paint pipes 122 and the paint nozzles 123 are opened, and the erasable paint stored in the paint storage box 121 will drip onto the fabric area with abnormal width through the paint nozzles 123.

[0026] The PLC controller 13 is fixedly arranged on the side wall of the detection box 4. The dust detection mechanism 8, the cleaning mechanism 9, the optical width detection mechanism 10, and the marking mechanism 12 are all electrically connected to the PLC controller 13.

[0027] Now, the operation principle of the present invention is described as follows: The staff installs the detection table 1 on the conveying and processing routes of the anti-wrinkle and high-elastic composite textile fabric, such as the printing and dyeing route and the cutting route, so that the fabric passes through the inside of the detection box 4 through the feed port 5 and then extends out through the discharge port 6. At the same time, both sides of the fabric are respectively guided by the feed guiding roller 2 and the discharge guiding roller 3, so that the fabric is located between the two limiting discs 14 on the feed guiding roller 2. Then, the staff needs to measure the fabric width in advance (the fabric width size may also be recorded on the label), and enter the obtained size parameters into the PLC controller 13. Based on the entered data, the PLC controller 13 will associate these width data with a designed resistance measuring device. In this device, the resistance rod 112 is connected to the circuit. Different fabric widths correspond to different resistance values ​​of the resistance rod 112 connected to the circuit, thereby generating electrical signals of different sizes. The PLC controller 13 sends instructions to the second cylinder 101, the third cylinder 103, the laser transmitter 104 and the laser receiver 105 to drive the second cylinder 101 and the third cylinder 103 to perform telescopic movements. The PLC width controller accurately controls the telescopic movement of the second cylinder 101 according to the pre-recorded fabric width electrical signal value, so that the bottom of the U-shaped plate 102 drives the slider 114 to slide in the measuring box 111 through the connecting column 115. At the same time, the conductive sleeves 113 on both sides connected to the slider 114 move synchronously on the resistance rod 112 until the resistance value of the resistance rod 112 connected to the circuit generates an electrical signal. The signal completely matches the signal value pre-recorded in the fabric width (the two ends of the resistor rod 112 are connected to the measuring circuit, and the current at the two ends of the resistor rod 112 can be measured, and then the electrical signal is amplified and filtered and sent back to the PLC controller 13). During the extension and retraction process, the second cylinder 101 drives the U-shaped plate 102 to move horizontally, so that the laser transmitter 104 and the laser receiver 105 installed on the U-shaped plate 102 move synchronously. During the movement, by adjusting the positions of the two in real time, the light beam emitted by the laser transmitter 104 can be just received by the laser receiver 105 until the fabric just blocks half of the light beam emitted by the laser transmitter 104. When the intensity of the light beam received by the laser receiver 105 is half of the light beam emitted by the laser transmitter 104, the system determines that the optical width detection mechanism 10 is accurately aligned with both sides of the fabric. The extension and retraction action of the third cylinder 103 can drive the laser receiver 105 to move upward or downward, and can adjust the distance between the laser transmitter 104 and the laser receiver 105 to be suitable for fabrics of different thicknesses. Finally, the staff manually operates the PLC controller 13 to start the vacuum cleaner 91. The operation of the vacuum cleaner 91 also generates negative pressure inside the third rubber suction pipe 99, which can timely suck the dust in the detection box 4, providing a clean and safe detection environment for the fabric width detection, and avoiding dust from interfering with the detection accuracy. At this point, the fabric width detection preparation work is ready; During the fabric conveying process, the limit disk 14 installed on the feeding guide roller 2 realizes adaptive adjustment with the help of the spring 16. When fabrics of different widths pass through the feeding guide roller 2, the acting forces on both sides of the fabric on the limit disk 14 are different, resulting in different degrees of compression of the spring 16. At the same time, the two limit disks 14 that can stretch and contract based on the elasticity of the spring 16 will exert a reverse acting force on the fabric, ensuring that when the fabric passes through the inside of the detection box 4, it can accurately pass through the optical width detection mechanism 10 installed on both sides inside the detection box 4, greatly reducing the detection error caused by fabric deviation. At the same time, the feeding guide roller 2 can play a role in guiding and flattening the fabric conveyed into the detection box 4, avoiding the phenomenon of fabric wrinkles or unevenness. Moreover, the fabric itself has strong anti-wrinkle performance, so the probability of fabric wrinkles or unevenness is small, significantly improving the detection accuracy.

[0028] Before the fabric enters the detection box 4, the dust sensors 82 installed above and below the feeding port 5 synchronously detect the dust on the upper and lower surfaces of the fabric (a light-emitting source is set inside the dust sensor 82. When the light shines on the fabric surface, if there is dust on the fabric surface, the light will be scattered on the dust particles, and the photodetector inside the dust sensor 82 can capture these scattered lights. According to the intensity, angle and other information of the scattered lights received by the photodetector, the dust situation on the fabric surface can be judged). The dust sensors 82 convert the detection data into electrical signals and transmit them to the width PLC width controller. Once the width PLC width controller receives a signal indicating that there is dust on the fabric surface, it will issue an instruction to start the dust collector 91 and the first cylinder 94, and open the first electromagnetic switch valve 910. When the dust collector 91 operates, a negative pressure environment is formed in the first rubber suction pipe 97, the second rubber suction pipe 98, the upper hollow plate 92 and the lower hollow plate 95. Since the upper hollow plate 92 is connected to the upper cleaning brush 93 and the lower hollow plate 95 is connected to the lower cleaning brush 96 respectively, under the action of negative pressure, the dust on the upper and lower surfaces of the fabric is sucked. At the same time, the first cylinder 94 extends, driving the upper hollow plate 92 to move downward, making the upper cleaning brush 93 closely contact with the upper surface of the fabric, and cooperating with the lower cleaning brush 96 to contact the lower surface of the fabric to clean the upper and lower surfaces of the moving fabric, greatly improving the dust cleaning effect, reducing the interference of dust impurities on the transmission and reflection of detection light, and improving the accuracy and reliability of measurement. If the dust sensors 82 do not detect dust on the surface of the fabric, the PLC width controller will not open the first electromagnetic switch valve 910 (during the process of the upper cleaning brush 93 and the lower cleaning brush 96 cleaning the upper and lower surfaces of the fabric, a small amount of dust may be generated. However, since the upper cleaning brush 93 and the lower cleaning brush 96 are relatively close to the upper hollow plate 92 and the lower hollow plate 95 respectively, the small amount of dust generated will be immediately blown and sucked away. Moreover, the optical width detection mechanism 10 is set inside the detection box 4, so the small amount of dust generated will not interfere with the optical path of the optical width detection mechanism 10); When the fabric enters the detection box 4, the degree of occlusion of the light beam emitted by the laser emitter 104 will vary for fabrics of different widths. If the fabric width is too large, the light-shielding area on both sides of the fabric for the laser beam will increase accordingly, and even completely block the laser beam. For fabrics with a small width, the light-shielding area for the laser beam will be reduced. In extreme cases, the laser beam will not be blocked. The laser receiver 105 will obtain corresponding signals based on the change in the received laser intensity. The received laser intensity will decrease due to a larger width and increase due to a smaller width. Subsequently, the laser receiver 105 will transmit the detection signal to the PLC controller 13; After receiving the signal indicating abnormal width, the PLC controller 13 will automatically trigger a control instruction to open the second electromagnetic solenoid valve 124. After 2 seconds, the PLC controller 13 will automatically close the second electromagnetic solenoid valve 124. During the opening of the second electromagnetic solenoid valve 124, the coating pipe 122 and the coating nozzle 123 are opened, and the erasable coating stored in the coating storage tank 121 will drip onto the fabric area with abnormal width through the coating nozzle 123 (since the fabric is in continuous transportation, the erasable coating drips onto the fabric in a linear shape, and later the staff can find the abnormal area of the fabric by identifying the approximate range of the mark). Since there are two sets of coating pipes 122 and coating nozzles 123, they can be independently opened according to the width detection results on both sides of the fabric, and can mark the position on one side of the fabric. This marking method greatly facilitates the staff to identify and process abnormal fabrics in the future. In addition, the erasable coating can be erased from the fabric after identification and processing, without leaving permanent marks on the fabric, ensuring the appearance and quality of the fabric in subsequent processing and use. Taking water-based coatings as an example, after the fabric is marked, if there is a small amount of residue, it can be removed by simple washing.
