Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically a woven fabric inspection and roll-up machine. Background Technology

[0002] Currently, textile roll-up inspection machines are also called fabric roll inspection machines, and further, they are simply called roll inspection machines. The reason for this name is that they have a dual function: firstly, they roll up the fabric after the final setting process for storage, transportation, and management; secondly, they inspect the fabric to prevent defective products from entering the market. More precisely, while the roll inspection machine is rolling up the fabric from the setting machine into a cylindrical shape, on-line operators observe the fabric's condition.

[0003] Existing fabric inspection and rolling machines often suffer from lint, thread ends, or debris accumulating on the roll roller or inspection area during the winding and inspection of woven fabrics. This not only interferes with the accuracy of manual or optical inspection but may also damage the fabric surface due to friction. Furthermore, the roll roller is prone to axial movement during winding, resulting in uneven fabric edges and requiring frequent manual adjustment of the limit device, leading to low efficiency. Therefore, we propose a new woven fabric inspection and rolling machine. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a woven fabric inspection and rolling machine. Through the micropores on the surface of the negative pressure roller, impurities such as lint and threads on the fabric surface are continuously adsorbed during the rolling process. The impurities are collected centrally through a rotary joint and a negative pressure system in the collecting cylinder, preventing their accumulation on the equipment or fabric surface. A knob drives a bidirectional screw to simultaneously adjust the positions of the side baffles and limit rods, precisely limiting the axial displacement of the rolling roller and ensuring neat fabric rolling edges, thus solving the problems mentioned earlier.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a woven fabric inspection and rolling machine, comprising a machine body, a negative pressure down-absorbing assembly installed on the top rear side of the machine body, and a rolling assembly and a limiting assembly installed on the front bottom side of the machine body; the negative pressure down-absorbing assembly includes a collecting cylinder, and fixed plates are fixedly connected to the left and right rear sides of the machine body; two sets of negative pressure rollers are arranged between the two sets of fixed plates, and several micro-holes are penetrating through the negative pressure rollers; a sliding groove is penetrating through each of the two sets of fixed plates.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 This utility model provides a technical solution: a woven fabric inspection and rolling machine, including a machine body 1, a negative pressure down suction component installed on the top rear side of the machine body 1, and a rolling component and a limiting component installed on the front bottom side of the machine body 1.

[0024] When the fabric rolling machine is running, the fabric is rolled up by the rolling assembly, and at the same time, the negative pressure suction assembly adsorbs the lint on the surface of the fabric through the negative pressure on the top and rear side. The limiting assembly restricts the axial displacement of the rolling assembly in real time to ensure stable rolling.

[0025] The negative pressure down suction assembly includes a collection cylinder 16. Fixing plates 18 are fixedly connected to the left and right rear sides of the equipment body 1. Two sets of negative pressure rollers 9 are arranged between the two sets of fixing plates 18. Several micro-holes are drilled through the negative pressure rollers 9. Sliding grooves 19 are drilled through the two sets of fixing plates 18. Sliding blocks 20 are slidably installed on the sliding grooves 19. An adjustment mechanism is installed on the sliding grooves 19. The two sets of negative pressure rollers 9 are rotatably installed between the two sets of fixing plates 18 and between the two sets of sliding blocks 20, respectively. Rotary joints 22 are fixedly connected to the right ends of the two sets of negative pressure rollers 9. A negative pressure pipe 23 is fixedly connected to the top side of the collection cylinder 16. The output ends of the two sets of rotary joints 22 are fixedly connected to the negative pressure pipe 23 through pipes. A negative pressure fan 14 is installed inside the rear side of the equipment body 1. A connecting pipe 15 is fixedly connected to the input end of the negative pressure fan 14. The input end of the connecting pipe 15 is fixedly connected to the bottom side of the collection cylinder 16.

[0026] The adjusting mechanism includes a screw 21, which is threaded through the top of the fixed plate 18, and the bottom end of the screw 21 is rotatably connected to the top of the sliding block 20.

[0027] When the negative pressure lint removal assembly is in use, the negative pressure fan 14 creates negative pressure in the collection cylinder 16 through the connecting pipe 15. The negative pressure is transmitted to the rotary joint 22 through the negative pressure pipe 23, driving the micropores on the surface of the two sets of negative pressure rollers 9 to adsorb lint and impurities on the fabric surface. The adsorbed impurities enter the negative pressure pipe 23 through the rotary joint 22 and the pipe, and are finally collected inside the collection cylinder 16. The collection cylinder 16 is equipped with a filter cylinder 17 for interception and collection. The rotating screw 21 drives the sliding block 20 to move along the sliding groove 19 on the fixed plate 18 through the threaded transmission, adjusting the distance between the two sets of negative pressure rollers 9 to adapt to fabrics of different widths and ensure comprehensive adsorption coverage. At the same time, the rotary joint 22 ensures a sealed connection between the negative pressure rollers 9 and the pipe when they rotate, achieving continuous and efficient lint removal.

[0028] The fabric rolling assembly includes a traction roller 10, a tension roller 11, and a fabric rolling roller 12. The traction roller 10 and the fabric rolling roller 12 are rotatably mounted between the left and right sides of the front of the equipment body 1, respectively. The fabric rolling roller 12 is located in front of the traction roller 10. The tension roller 11 is located between the traction roller 10 and the fabric rolling roller 12. A tension adjustment mechanism is installed between the tension roller 11 and the equipment body 1. A drive motor 13 is installed inside the equipment body 1. A pulley 4 is fixedly connected to the output shaft of the drive motor 13. A pulley 6 is fixedly sleeved on the right side of the rotating shaft of the fabric rolling roller 12. A belt 5 is tensioned and sleeved between the pulley 4 and the pulley 6.

[0029] The tension adjustment mechanism includes two sets of sliding blocks 32. Sliding grooves 31 are provided on the left and right sides of the front part of the equipment body 1. The two sets of sliding blocks 32 are slidably installed on the two sets of sliding grooves 31 respectively. The tension roller 11 is rotatably installed between the two sets of sliding blocks 32. Several telescopic rods 34 are fixedly connected between the top side of the sliding block 32 and the top side of the sliding groove 31. Springs 33 are sleeved on the telescopic rods 34.

[0030] When the fabric winding assembly is in use, the drive motor 13 drives the winding roller 12 to rotate through the belt 5 between the pulley 4 and the pulley 6. After being guided by the traction roller 10, the fabric passes around the tension roller 11 and is wound up by the winding roller 12. The tension roller 11 is installed in the sliding groove 31 of the equipment body 1 through the sliding block 32. The elastic action of the telescopic rod 34 and the spring 33 allows the sliding block 32 to move up and down. The height of the tension roller 11 is automatically adjusted according to the fabric tension to maintain uniform and stable tension during the fabric winding process.

[0031] The limiting component includes a knob 24. A mounting groove 25 is fixedly connected between the left and right sides of the front of the equipment body 1. A bidirectional screw 26 is rotatably inserted between the left and right sides of the mounting groove 25. The knob 24 is fixedly connected to the left end of the bidirectional screw 26. Sliding plates 27 are slidably connected to the left and right sides inside the mounting groove 25. Both sets of sliding plates 27 are threaded onto the bidirectional screw 26. A baffle 28 is rotatably installed at the front of the sliding plate 27. A limiting plate 29 is fixedly connected to the front side of the sliding plate 27. A limiting rod 30 is fixedly connected to the side of the baffle 28 near the limiting plate 29. The outer surface of the limiting rod 30 abuts against the top side of the limiting plate 29. The bottom side of the baffle 28 abuts against the outer surface of the fabric rolling roller 12.

[0032] When the limiting component is in use, the knob 24 drives the bidirectional screw 26 to rotate. The thread action of the bidirectional screw 26 causes the sliding plates 27 on both sides to move in opposite directions along the mounting groove 25. The sliding plates 27 drive the baffle 28 to move synchronously. The bottom side of the baffle 28 abuts against the outer surface of the fabric rolling roller 12, restricting its axial movement. At the same time, the limiting rod 30 abuts against the top side of the limiting plate 29, constraining the rotation angle of the baffle 28, ensuring that the baffle 28 is in stable contact with the fabric rolling roller 12, and realizing axial limiting.

[0033] A light-emitting panel 35 is installed on the top center of the device body 1, and a mounting frame 2 is also installed on the top center of the device body 1. A transparent observation window 3 is provided on the mounting frame 2, and a CCD vision camera 7 and an infrared thermal imaging sensor 8 are installed on the side of the mounting frame 2 near the light-emitting panel 35. When the fabric passes through the detection area, the light-emitting panel 35 provides uniform backlight illumination. Through the transparent observation window 3, the CCD vision camera 7 captures optical images of fabric surface defects, and the infrared thermal imaging sensor 8 simultaneously detects the infrared radiation distribution of the fabric and identifies thermal anomaly areas, thus realizing the dual detection of fabric surface defects and internal structural problems.

[0034] The collection cylinder 16 is equipped with a filter cylinder 17 to intercept and collect impurities.

[0035] Working Principle: When the fabric winding machine is running, the drive motor 13 drives the winding roller 12 to rotate via the belt 5 between pulley 4 and pulley 6. The fabric is guided by the traction roller 10, passes over the tension roller 11, and is wound up by the winding roller 12. The tension roller 11 is installed in the sliding groove 31 of the equipment body 1 via the sliding block 32. The elastic action of the telescopic rod 34 and the spring 33 allows the sliding block 32 to move up and down, automatically adjusting the height of the tension roller 11 according to the fabric tension to maintain uniform and stable tension during the fabric winding process. At the same time, the negative pressure fan 14 creates negative pressure in the collection cylinder 16 through the connecting pipe 15. The negative pressure is transmitted to the rotary joint 22 via the negative pressure pipe 23, which drives the micropores on the surface of the two sets of negative pressure rollers 9 to adsorb the lint and impurities on the fabric surface. The adsorbed impurities enter the negative pressure pipe 23 through the rotary joint 22 and the pipe, and are finally collected inside the collection cylinder 16. The collection cylinder 16 is equipped with a filter cylinder 17 for interception and collection. The rotating screw 21 drives the sliding block 20 to move along the sliding groove 19 on the fixed plate 18 through the threaded transmission, adjusting the distance between the two sets of negative pressure rollers 9 to adapt to fabrics of different widths and ensure comprehensive adsorption coverage. At the same time, the rotary joint 22 ensures a sealed connection between the negative pressure rollers 9 and the pipe when they rotate, achieving continuous and efficient lint removal.

[0036] Before the fabric is rolled, the double-sided screw 26 is driven to rotate by the knob 24. The thread action of the double-sided screw 26 causes the sliding plates 27 on both sides to move in opposite directions along the mounting groove 25. The sliding plates 27 drive the baffle 28 to move synchronously. The bottom side of the baffle 28 abuts against the outer surface of the fabric rolling roller 12, restricting its axial movement. At the same time, the limiting rod 30 abuts against the top side of the limiting plate 29, constraining the rotation angle of the baffle 28, ensuring that the baffle 28 and the fabric rolling roller 12 are in stable contact, and achieving axial limiting. When the fabric passes through the detection area, the light-emitting panel 35 provides uniform backlight illumination. Through the transparent observation window 3, the CCD vision camera 7 captures optical images of fabric surface defects. The infrared thermal imaging sensor 8 simultaneously detects the infrared radiation distribution of the fabric, identifies thermal anomaly areas, and achieves dual detection of fabric surface defects and internal structural problems.
