Description

Technical Field

[0001] The utility model relates to the technical field of cloth inspection and coding machines, in particular to a cloth inspection and coding machine used for cloth inspection. Background Art

[0002] The fabric inspection and coding machine is a mechanical device that combines fabric inspection and coding functions, and is widely used in the textile, clothing, leather, and other industries. It is primarily used to check fabric for missing warp and weft threads, surface damage, and lint. After inspection by the fabric inspection device, the fabric is collected and organized by the fabric collection device, completing the fabric inspection. Through the coordinated operation of various components, accurate fabric inspection and efficient coding are achieved.

[0003] The patent document with application number 202123019197.8 discloses a semi-intelligent cloth inspection machine, including a cloth conveying system and a cloth inspection system. The cloth conveying system is used to drive the cloth through the cloth inspection area, and the cloth inspection system is used to perform defect inspection on the cloth in the cloth inspection area. The cloth inspection system includes a cloth length counter, an infrared touch frame and a computer. The cloth length counter is used to detect the real-time length information of the conveyed cloth and transmit it to the computer.

[0004] However, traditional fabrics may react with conveyor rollers or particles in the air during transportation, thereby generating static electricity. Static electricity can cause the surface of the fabric to absorb pollutants such as dust and impurities in the air. These pollutants may mask the defects of the fabric itself, making it difficult for defect detection equipment or manual inspection to accurately identify defects. In addition, dust accumulated over a long period of time may also contaminate components such as lenses and sensors of the detection equipment, affecting detection accuracy. Utility Model Content

[0005] The utility model discloses a cloth inspection and coding machine for cloth inspection, which aims to solve the technical problem that traditional cloth may react with conveying rollers or particles in the air during transportation, thereby generating static electricity. Due to the static electricity, the cloth surface will absorb pollutants such as dust and impurities in the air. These pollutants may mask the defects of the cloth itself, making it difficult for defect detection equipment or manual inspection to accurately identify defects. In addition, the dust accumulated over a long period of time may also cause pollution to the lens, sensor and other components of the detection equipment, affecting the detection accuracy.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A cloth inspection and coding machine for cloth inspection comprises a frame and two mounting brackets mounted on the top outer wall of the frame, a cloth inspection lamp and an infrared sensor are provided between the two mounting brackets, and further comprises:

[0008] Flattening and cleaning mechanism: located on the top outer walls of the two mounting frames, the flattening and cleaning mechanism includes two side panels and an air pipe, an air cylinder is provided between the two side panels, the air pipe runs through one side outer wall of one of the side panels, and one end of the air pipe is communicated with the interior of the air cylinder, a plurality of flattening components are provided on the circumferential outer wall of the air cylinder near the bottom end, the flattening components include two connecting frames, one end of the connecting frame is connected to an unfolding wheel through a bearing, a plurality of air blowing pipes are provided on the circumferential outer wall of the air cylinder near the cloth inspection light, and the air blowing pipes are located between two adjacent unfolding wheels;

[0009] The transmission mechanism is located between the inner walls on opposite sides of the frame.

[0010] When in use, pass the end of the fabric to be inspected between the frame and the conduction mechanism, manually drag the end of the fabric to be inspected to the winding device behind the frame, and then turn on the infrared sensor and fabric inspection light on the fabric inspection and coding machine. During the fabric transmission through the conduction mechanism, the static electricity generated by the friction on the fabric surface can be eliminated, and then the angle between the two adjacent unfolding wheels can be used to achieve the effect of horizontally stretching and pressing the fabric. After the fabric is pressed down, the wrinkles are flattened, and then the air is continuously blown into the air cylinder through the air pipe, and the static electricity adsorbed on the fabric by the air pipe is removed. Dust, impurities and other pollutants in the air are blown away to prevent these pollutants from covering up the defects of the fabric itself, thereby affecting the accurate identification of defects by the equipment. The fabric then continues to move toward the winding device, and the defects on the fabric surface are detected by using a fabric inspection light and an infrared sensor. This device can improve detection accuracy, reduce the impact of electrostatic adsorption of dust, impurities and other pollutants on fabric defect identification, make defect detection more accurate, avoid misjudgment or missed detection due to external factors, improve the cleanliness of the fabric, and ensure the purity of the fabric and production quality.

[0011] In a preferred solution, the transmission mechanism includes four mounting blocks, a limiting roller and two limiting plates, the four mounting blocks are respectively mounted on the outer walls on both sides of the frame, two cloth guide rollers are arranged between the four mounting blocks, a motor is provided on one side outer wall of one of the mounting blocks, the output shaft of the motor is fixedly connected to one end of the cloth guide roller, a connecting belt is provided on the circumferential outer wall of the two cloth guide rollers, the two limiting plates are respectively close to the two ends of the cloth guide rollers, the limiting roller is located between the two cloth guide rollers, a fixed shaft column is provided on one side outer wall of the two limiting plates, a flattening roller and an anti-static component are provided between the two limiting plates, the flattening roller is connected to the fixed shaft column through a bearing, a thread is provided on the circumferential outer wall of the flattening roller, and the limiting plate is an "M" shaped structure.

[0012] The output shaft of the motor drives one of the cloth guide rollers to rotate, and under the connecting action of the connecting belt and the limiting action of the limiting roller, it drives the other cloth guide roller to rotate, thereby realizing the smooth transmission of the cloth. The "M"-shaped limit plate has better inclusiveness and stability, and can adapt to cloths of different widths and thicknesses. At the same time, it plays a supporting and limiting role for the static electricity elimination component. The threaded design on the flattening roller helps to slightly stretch and flatten the cloth, reduce wrinkles, and the setting of the static electricity elimination component can effectively remove the static electricity generated by the cloth during transmission, and prevent static electricity from adsorbing dust and impurities and having a greater impact on cloth quality detection.

[0013] In a preferred solution, the static elimination component includes a mounting roller, and two static elimination bars are provided on the circumferential outer wall of the mounting roller, and one end of the static elimination bar is an arc-shaped structure.

[0014] The arc-shaped design creates a wider contact area between the static elimination bar and the fabric, and this shape promotes the even distribution and dissipation of static charges. Compared to straight or sharp designs, the arc shape can more effectively reduce the static charge density on the fabric surface, thereby improving the efficiency of static elimination.

[0015] As can be seen from the above, a cloth inspection and coding machine for cloth inspection includes a frame and two mounting brackets mounted on the top outer wall of the frame, a cloth inspection lamp and an infrared sensor are provided between the two mounting brackets, and further includes:

[0016] Flattening and cleaning mechanism: located on the top outer walls of the two mounting frames, the flattening and cleaning mechanism includes two side panels and an air pipe, an air cylinder is provided between the two side panels, the air pipe runs through one side outer wall of one of the side panels, and one end of the air pipe is communicated with the interior of the air cylinder, a plurality of flattening components are provided on the circumferential outer wall of the air cylinder near the bottom end, the flattening components include two connecting frames, one end of the connecting frame is connected to an unfolding wheel through a bearing, a plurality of air blowing pipes are provided on the circumferential outer wall of the air cylinder near the cloth inspection light, and the air blowing pipes are located between two adjacent unfolding wheels;

[0017] The conductive mechanism is located between the inner walls of the frame on opposite sides. The cloth inspection and coding machine provided by the utility model has the technical effect of improving detection accuracy, reducing the influence of dust, impurities and other pollutants adsorbed by static electricity on the identification of cloth defects, making defect detection more accurate, avoiding misjudgment or missed detection due to external factors, improving the cleanliness of the cloth, and ensuring the purity of the cloth and production quality.

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work fall within the scope of protection of the present application.

[0023] The utility model discloses a cloth inspection and coding machine for cloth inspection, which is mainly used in scenarios where traditional cloth may react with conveyor rollers or particles in the air during transportation, thereby generating static electricity. Since static electricity causes the cloth surface to absorb pollutants such as dust and impurities in the air, these pollutants may mask the defects of the cloth itself, making it difficult for defect detection equipment or manual inspection to accurately identify defects. In addition, dust accumulated over a long period of time may also contaminate components such as lenses and sensors of the detection equipment, affecting detection accuracy.

[0024] Reference Figure 1 and Figure 3 A cloth inspection and coding machine for cloth inspection includes a frame 1 and two mounting frames 2 mounted on the top outer wall of the frame 1, a cloth inspection lamp 3 and an infrared sensor 10 are provided between the two mounting frames 2, and further includes:

[0025] Flattening and cleaning mechanism: Located on the top outer wall of the two mounting frames 2, the flattening and cleaning mechanism includes two side panels 16 and an air pipe 12. An air cylinder 13 is provided between the two side panels 16. The air pipe 12 runs through the outer wall of one side of the side panels 16, and one end of the air pipe 12 is communicated with the interior of the air cylinder 13. Several flattening components are provided on the circumferential outer wall of the air cylinder 13 near the bottom end. The flattening components include two connecting frames 19, one end of the connecting frame 19 is connected to the unfolding wheel 20 through a bearing, and several air blowing pipes 18 are provided on the circumferential outer wall of the air cylinder 13 near the cloth inspection light 3. The air blowing pipe 18 is located between two adjacent unfolding wheels 20.

[0026] Conduction mechanism: located between the inner walls on opposite sides of the frame 1.

[0027] The connecting frame 19 is L-shaped, with the controller 11 located on one side of one of the mounting frames 2. As a key component supporting the unfolding wheel 20, the L-shaped design provides enhanced stability. This structure effectively disperses and resists stress from the unfolding wheel 20 and the fabric, reducing the risk of deformation and damage.

[0028] During specific use, the nozzle of the air blowing tube 18 is tilted downward. The downward tilted nozzle design helps prevent the blown air flow from flowing back, preventing the removed pollutants from being brought back to the target area and causing secondary pollution.

[0029] Among them, the surface of the unfolding wheel 20 is wrapped with an anti-slip pad. The surface of the anti-slip pad has a corrugated structure. The anti-slip pad is made of rubber material. The corrugated structure of the anti-slip pad can increase the contact area with the fabric and form multiple tiny contact points, thereby significantly improving the friction. This enhanced friction helps to better grasp and guide the fabric, preventing the fabric from slipping or deflecting during the unfolding process. By applying pressure evenly, the corrugated anti-slip pad can reduce damage or deformation of the fabric caused by excessive local pressure.

[0030] During the specific implementation process, the unfolding wheel 20 is arranged in an inclined shape, and the upper end spacing of two adjacent unfolding wheels 20 is smaller than the lower end spacing. The small upper end spacing of two adjacent unfolding wheels 20 helps to reduce the wrinkles and unevenness of the cloth at the starting position. As the cloth unfolds, the increase in the lower end spacing allows the cloth to gradually relax and naturally flatten, thereby improving the overall flatness of the cloth.

[0031] Specifically, when in use, the end of the cloth to be inspected is passed between the frame 1 and the conducting mechanism, and the end of the cloth to be inspected is manually dragged to the winding device behind the frame 1, and then the infrared sensor 10 and the cloth inspection lamp 3 on the cloth inspection and coding machine are turned on. During the transmission of the cloth through the conducting mechanism, the static electricity generated by the friction on the surface of the cloth can be eliminated, and then the angle between the two adjacent unfolding wheels 20 can be used to achieve the effect of horizontally stretching and pressing the cloth. After the cloth is pressed down, the wrinkles at the cloth are flattened, and then the air is continuously blown into the air cylinder 13 through the air pipe 12, and the air pipe 18 is used to remove the static electricity on the cloth. The dust, impurities and other pollutants are blown away to prevent these pollutants from covering up the defects of the fabric itself, thereby affecting the accurate identification of defects by the equipment. The fabric then continues to move toward the winding device, and the defects on the fabric surface are detected by the fabric inspection lamp 3 and the infrared sensor 10. The data is transmitted to the controller 11 for storage through the line. The device can improve the detection accuracy, reduce the influence of electrostatic adsorption of dust, impurities and other pollutants on the identification of fabric defects, make the defect detection more accurate, avoid misjudgment or missed detection due to external factors, improve the cleanliness of the fabric, and ensure the purity and production quality of the fabric.

[0032] Reference Figure 1 and Figure 2 In a preferred embodiment, the transmission mechanism includes four mounting blocks 5, a limiting roller 9 and two limiting plates 4. The four mounting blocks 5 are respectively mounted on the outer walls on both sides of the frame 1. Two cloth guide rollers 7 are arranged between the four mounting blocks 5. A motor 6 is provided on the outer wall of one side of one of the mounting blocks 5. The output shaft of the motor 6 is fixedly connected to one end of the cloth guide roller 7. A connecting belt 8 is provided on the circumferential outer wall of the two cloth guide rollers 7. The two limiting plates 4 are respectively close to the two ends of the cloth guide roller 7. The limiting roller 9 is located between the two cloth guide rollers 7. A fixed shaft column 15 is provided on the outer wall of one side of the two limiting plates 4. A flattening roller 14 and an anti-static component are provided between the two limiting plates 4. The flattening roller 14 is connected to the fixed shaft column 15 through a bearing. The circumferential outer wall of the flattening roller 14 is provided with a thread, and the limiting plate 4 is an "M"-shaped structure.

[0033] Specifically, the output shaft of the motor 6 drives one of the cloth guide rollers 7 to rotate, and under the connecting action of the connecting belt 8 and the limiting action of the limiting roller 9, drives the other cloth guide roller 7 to rotate, thereby realizing the smooth transmission of the cloth. The "M"-shaped limit plate 4 has better inclusiveness and stability, and can adapt to cloths of different widths and thicknesses. At the same time, it plays a supporting and limiting role for the static electricity elimination component. The threaded design on the flattening roller 14 helps to slightly stretch and flatten the cloth, reduce wrinkles, and the setting of the static electricity elimination component can effectively remove the static electricity generated by the cloth during transmission, and prevent static electricity from adsorbing dust and impurities from having a greater impact on cloth quality detection.

[0034] Reference Figure 1 and Figure 2 In a preferred embodiment, the static elimination assembly includes a mounting roller with two static elimination bars 17 positioned on its circumferential outer wall. One end of each bar 17 is arc-shaped. This arc-shaped design creates a wider contact area with the fabric, facilitating the even distribution and dissipation of static electricity. Compared to straight or pointed designs, the arc-shaped design more effectively reduces static charge density on the fabric surface, thereby improving static elimination efficiency.

[0035] Working principle: When in use, the end of the fabric to be inspected is passed between the frame 1 and the conduction mechanism, and the end of the fabric to be inspected is manually dragged to the winding device behind the frame 1, and then the infrared sensor 10 and the fabric inspection lamp 3 on the fabric inspection and coding machine are turned on. During the transmission of the fabric through the conduction mechanism, the static electricity generated by the friction on the fabric surface can be eliminated, and then the angle between the two adjacent unfolding wheels 20 can be used to achieve the effect of horizontally stretching and pressing the fabric. After being pressed down, the wrinkles of the fabric are flattened, and then air is continuously blown into the air guide cylinder 13 through the air supply pipe 12, and the air pipe 18 is used to blow away the dust, impurities and other pollutants in the air adsorbed by the previous static electricity on the fabric, so as to prevent these pollutants from covering up the defects of the fabric itself, thereby affecting the accurate identification of defects by the equipment. Then the fabric continues to move toward the winding device, and the defects on the fabric surface are detected by the cooperation of the fabric inspection lamp 3 and the infrared sensor 10.

The replacements described may be partial structures, devices, or method steps, or they may be complete technical solutions. Any equivalent replacements or modifications based on the technical solution and the concept of the present invention shall be covered by the scope of protection of the present invention.
