Description

Technical Field

[0001] The utility model belongs to the technical field of fabric detection, in particular to a linear array fabric inspection machine. Background Art

[0002] The fabric inspection machine is a device used to inspect the quality of fabrics. Its principle is to detect defects on the surface of fabrics by passing the fabrics through the lighting system and sensors on the machine. However, during the inspection process, the flatness of the fabrics needs to be ensured, and after the rolls are changed, there will be joints between the fabrics. Therefore, the two rollers that clamp the fabrics are not set at the corresponding position of the fabric inspection machine. When the fabrics pass through the fabric inspection table, the fabrics near the two sides of the fabric inspection table will sag due to the gravity of the fabrics themselves, and the traditional fabric inspection table will not adjust the height according to the sagging degree of the fabrics, resulting in wrinkles in the fabrics during the dragging process. Summary of the invention

[0003] The utility model aims to solve the above problems in the prior art and proposes a linear array fabric inspection machine, which has the characteristics of adjustable height of the fabric inspection table, better fabric conveying and reduced wrinkles.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 4 As shown, a linear array fabric inspection machine comprises: a frame 2, a fabric inspection platform 3, a plurality of cameras 4 and a plurality of light sources 5. A light transmission hole 311 is provided in the middle of the fabric inspection platform 3. The fabric inspection platform 3 is connected to the frame 2 through two linear guide rails and can move up and down relative to the frame 2; the camera 4 is fixed on the frame 2, and the lens of the camera is facing the light transmission hole 311 of the fabric inspection platform 3; the light source 5 is fixed on the frame 2, and the light source 5 is aimed at the fabric inspection platform 3.

[0033] In the present application, the height of the fabric inspection platform 3 can be adjusted according to the fabric weights, and the height can be adjusted according to the degree of fabric sagging, so as to prevent the fabric from directly hitting the edge of the fabric inspection platform 3, and then entering the light-transmitting hole 311 of the fabric inspection platform 3, thereby reducing the occurrence of wrinkles. The height of the fabric inspection platform 3 can be controlled by two linear guide rails, and the height of the fabric inspection platform 3 can be conveniently adjusted. Compared with the traditional fabric inspection platform 3 that cannot adjust the height, it is more convenient and reduces fabric wrinkles.

[0034] Specifically, it also includes a transmission roller 6, a pressure roller 7, two cylinders 8 and a connecting piece 9. The transmission roller 6 is rotatably set on the frame 2. The connecting piece 9 is L-shaped. One end of the connecting piece 9 is rotatably connected to the frame 2. The pressure roller 7 is rotatably connected to the middle part of the connecting piece 9. The other end of the connecting piece 9 is rotatably connected to the piston rod of the cylinder 8. The cylinder bodies of the two cylinders 8 are rotatably connected to the frame 2.

[0035] In the present application, when the fabric is normally input, the cooperation between the transmission roller 6 and the pressure roller 7 allows the fabric to enter the fabric inspection table 3 stably, effectively reducing the generation of wrinkles. When the splicing position of the fabric passes through the transmission roller 6 and the pressure roller 7, the cylinder 8 will drive the pressure roller 7 to move up, increasing the gap between the pressure roller 7 and the transmission roller 6. This can avoid the splicing position from damaging the pressure roller 7. After the splicing position is passed, the cylinder 8 acts again to move the pressure roller 7 down so that the fabric is close to the transmission roller 6, and the fabric continues to be transported stably. This design not only protects the pressure roller 7, but also ensures the continuity and stability of fabric processing.

[0036] Specifically, the fabric inspection platform 3 has a support surface 31 , on which light-transmitting holes 311 are provided along the length direction of the fabric inspection platform 3 ; sliders of two linear guide rails are respectively connected to the two ends of the fabric inspection platform 3 .

[0037] The support table is provided with a light-transmitting hole 311, which means that when the cloth passes through the support table, light can pass through the light-transmitting hole 311 for illumination, thereby facilitating the detection of minor defects and quality problems on the surface of the cloth. The sliders on the two linear guide rails are respectively connected to the two ends of the support table, so that the support table can move up and down along the guide rails, which provides great flexibility for adjusting the tension and position of the cloth. This structure can adapt to the thickness of the cloth and reduce the problems caused by the sagging or unevenness of the cloth.

[0038] Specifically, the fabric inspection platform 3 further comprises guide portions 32 arranged on both sides of the support surface 31 and light shielding portions 33 connected to the guide portions 32 . The light shielding portions 33 are parallel to the support surface 31 , and adjacent light shielding portions 33 have intervals corresponding to the light transmission holes 311 .

[0039] The light source 5 can enter through interval illumination and emit from the light transmission hole 311. After the light enters the interior of the support platform, part of the light may be reflected internally. These reflected light rays can be shielded by the light shielding portion 33, so that the interior of the support platform is adjusted to be brighter, thereby increasing the brightness and being able to better capture the passing fabric.

[0040] Specifically, the guide portion 32 is in an arc shape.

[0041] The curved guide portion 32 can guide the fabric more smoothly, reducing the friction and pulling that may be caused by right angles or sharp edges, which is especially important for delicate or fragile fabrics. The curved design also helps the fabric to pass smoothly, avoiding the fabric from getting stuck or gathering during the guiding process, which not only protects the fabric, but also improves the continuity and efficiency of the detection process.

[0042] Specifically, the orthographic projection of the light-transmitting hole 311 is within the interval.

[0043] This design maximizes direct light utilization and enhances the lighting effect, thereby improving the quality and accuracy of image capture.

[0044] Specifically, vertical plates 34 are fixed at both ends of the fabric inspection platform 3 , the vertical plates 34 are connected to the support surface 31 , the guide portion 32 , and the light shielding portion 33 , and the vertical plates 34 are connected to the slider of the linear guide rail.

[0045] The addition of the vertical plate 34 as a structural support point can increase the stability and rigidity of the entire support platform. This stability is the key to ensure that the fabric inspection machine maintains accuracy and consistency during operation, especially when processing large fabrics.

[0046] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative position relationship and movement status of the components in a certain specific posture, as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0047] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.
