Description

Technical Field

[0001] The utility model relates to the technical field of fabric inspection equipment, and specifically, to a fabric defect marking device for a fabric inspection machine. Background Technique

[0002] With the improvement of people's living standards, the quality requirements for the fabrics produced by textile enterprises are increasing day by day. Defects on textile fabrics not only affect the aesthetics of the fabrics but also the comfort of wearing them. Fabric defect detection plays a very important role in the production of the textile industry. The price of fabrics with defects will be reduced. Therefore, defect detection is the last step before the finished fabric leaves the factory and an important process in the quality control of textile production;

[0003] After the existing defect inspection and marking, there is a lack of a function for recording the position of the marking points, which requires manual recording. This is not conducive to the staff quickly finding the defects for processing and is prone to omissions. The existing defect inspection and marking are usually manually positioned and marked according to the alarm. This marking method has high efficiency, but the marking is inaccurate and prone to errors.

[0004] The patent with the application number CN202221986001.4 discloses a fabric defect inspection and marking device for a fabric inspection machine, including a bracket, an unwinding roller, a winding roller, a motor, a punctuation recording mechanism, an inspection mechanism, and a marking mechanism. A winding roller is rotatably provided on one side of the bracket, an unwinding roller is rotatably provided on the other side of the bracket, a motor is fixedly provided at the front end of the other side of the bracket, the output end of the motor is drivingly connected to the winding roller, a turntable is fixedly provided on the front side of the winding roller, convex blocks are symmetrically fixedly provided on the upper and lower sides of the turntable, an infrared sensor is fixedly provided at the front end of one side of the bracket, a counter is fixedly provided above the infrared sensor, a marking mechanism is provided on one side in the middle of the bracket, and an inspection mechanism is provided on the other side in the middle of the bracket; the utility model records the number of rotations of the winding roller by the cooperation of the convex block and the infrared sensor when the turntable rotates, accurately records the number of rotations when the defect is found, which is beneficial to the winding roller to roll back to find the defect and avoid omission. The strip-shaped light-emitting plate and the light-receiving induction plate cooperate to quickly and accurately detect the defect through the change of light and darkness, avoiding inaccurate manual inspection and marking.

[0005] This structure inspects the defects of the fabric being transported at the bottom through a detection frame and then marks the defects with a marking pen at the back. However, in this structure, if the distance between the defects is relatively close, a single group of marking pens cannot meet the defect marking requirements. At the same time, if the marked points are not dried directly after marking, it will contaminate other positions of the fabric and it is difficult to distinguish the defect positions.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0023] Please refer to Figures 1 to 4 , in the present utility model, a fabric inspection machine defect marking device includes a mounting frame 1, a rewinding roller 2 and an unwinding roller 3. The rewinding roller 2 and the unwinding roller 3 are both installed on the mounting frame 1. A detection frame 4 is fixedly installed on the mounting frame 1. A strip-shaped light-emitting plate 5 is fixedly installed on the inner top wall of the detection frame 4. A light-receiving induction plate 6 is installed on the inner wall of the detection frame 4. The light-receiving induction plate 6 is located at the bottom of the strip-shaped light-emitting plate 5. A processor 7 is integrated inside the mounting frame 1. The light-receiving induction plate 6 is signal-connected to the processor 7. A marking frame 8 is installed on the top of the mounting frame 1. A marking component 9 is arranged inside the marking frame 8. The marking component 9 is signal-connected to the processor 7. A drying frame 10 is fixedly installed on the top of the mounting frame 1. The top of the drying frame 10 is fixedly connected to an air box 11. A plurality of air nozzles 12 arranged at equal distances are installed on the inner bottom wall of the air box 11. An electric control valve 13 is fixedly installed at the top end of the air nozzle 12. An air pump 14 communicated with the inside thereof is fixedly installed on the top of the air box 11. Both the air pump 14 and the electric control valve 13 are signal-connected to the processor 7.

[0024] The marking component 9 includes an electric guide rail 901. The electric guide rail 901 is fixedly installed on the inner top wall of the marking frame 8. A plurality of uniformly distributed electric push rods 902 are slidably installed on the electric guide rail 901. A marking pen 903 is fixedly installed at the bottom end of the electric push rod 902. Both the electric push rod 902 and the electric guide rail 901 are signal-connected to the processor 7;

[0025] The recording module 17 is integrated inside the mounting bracket 1, and the recording module 17 is signal-connected to the processor 7.

[0026] Among them, the light-receiving induction plate 6 is used in conjunction with the optical signal analyzer, and the winding roller 2 and the unwinding roller 3 cooperate to realize the conveying of the fabric. The strip-shaped light-emitting plate 5 is turned on. When there is a defect on the fabric, the light passes through the defect and falls on the light-receiving induction plate 6. After that, the light-receiving induction plate 6 converts the position information of the sensed light into an electrical signal and transmits it to the optical signal analyzer. Then, after obtaining the position, the signal is transmitted to the processor 7. The processor 7 controls the operation of the marking component 9 in the marking frame 8. Multiple electric push rods 902 can move simultaneously. The electric guide rail 901 drives the electric push rod 902 to move to the horizontal line of the defect position. Then, the electric push rod 902 moves downward. As the fabric continues to move, when the marking pen 903 touches the fabric, the defect position moves to the position of the marking pen 903, and the marking pen 903 marks the defect position of the fabric. If the detection frame 4 detects that two defect positions are relatively close, different electric push rods 902 will be used for marking. At the same time, the recording module 17 will record to facilitate obtaining data and verification during subsequent repair. Then, the processor 7 controls the operation of the air pump 14. The air pump 14 generates suction to send external gas into the air box 11 to form an air flow. Then, the processor 7 controls the corresponding electromagnetic control valve 13 corresponding to the defect position to open. Then, the air flow is ejected through the corresponding air nozzle 12, and the marked position of the marking pen 903 is dried by the air flow and then dried. Subsequently, the winding is completed by the winding roller 2.

[0027] In the present utility model, the defect detection of the bottom-transported fabric is carried out through the cooperation of the strip-shaped light-emitting plate 5 and the light-receiving induction plate 6. Subsequently, the marking component 9 can mark multiple defect positions, which is convenient for subsequent repair. At the same time, the air drying component is used to dry the marking points, which can ensure that the ink has dried before winding, thereby avoiding the ink from staining other parts of the fabric. At the same time, the dried marking is more firm and not easily erased or blurred, which is helpful for subsequent quality inspection and tracking.

[0028] Please refer to Figure 1 and 2 wherein: a support plate 15 is fixedly connected to the inner wall of the marking frame 8, and the support plate 15 is located at the bottom of the marking component 9.

[0029] In the present utility model, the support plate 15 is at the bottom of the fabric. When the marking component 9 marks the fabric, the support plate 15 at the bottom can play a supporting role to prevent the fabric from deforming under pressure.

[0030] Please refer to Figure 1 and 4 wherein: a status indicating lamp 16 is fixedly installed on the top of the detection frame 4, and the status indicating lamp 16 is signal-connected to the processor 7.

[0031] In the present utility model, when the detection frame 4 detects a defect in the fabric, the processor 7 will control the status indicator light 16 to light up, so as to play a prompting role for personnel, facilitating the user to understand the status of the device.

[0032] Please refer to Figure 1 , wherein: the detection frame 4, the marking frame 8 and the drying frame 10 are all detachably connected to the mounting frame 1 by bolts.

[0033] In the present utility model, this method can facilitate the disassembly, assembly and maintenance of the device, and can be replaced separately when a single frame body is damaged.

[0034] The above is only the preferred specific implementation manner of the present utility model; however, the protection scope of the present utility model is not limited thereto.
