Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of garment manufacturing, in particular, the present application relates to a fabric detection equipment with over force protection. BACKGROUND

[0002] With the improvement of people's living standards, the requirements for the fabric produced by textile enterprises are also getting higher and higher. The fabric needs high-temperature printing and dyeing, forming and other processes during processing. After the fabric processing is completed, the fabric needs to be detected to find out the defects and stains. Some fabrics with higher design requirements also need to detect the compression and friction resistance performance on the surface of the fabric.

[0003] For example, Chinese patent invention patent CN114192435A discloses a fabric detection equipment, which comprises a rack, a feeding mechanism, a material receiving mechanism, a tensioning mechanism, a first light source, a first laser, a first camera and a control module. By arranging a high-speed camera on one side or both sides of the fabric, the corresponding image information is obtained by taking a picture of the passing fabric through the high-speed camera. At the same time, when there is a hole with a certain diameter on the surface of the fabric, the imaging of the linear laser on the surface of the fabric is in a disconnected state, so that the control module can judge whether the defect type of the defect area is a hole or a stain. Compared with manual detection, the efficiency is higher.

[0004] However, the above-mentioned fabric detection equipment still has the following shortcomings: it can only check the dirt on the surface of the fabric, but it cannot simulate the printing effect on the surface of the fabric under compression and friction resistance for detection, and it needs to detect the fabric after tensioning. The tensile properties of different parts of the fabric during the detection process are not the same, which can easily damage the structure of the fabric, the detection function is single, and the detection effect is poor.

In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0031] Techniques, methods, and systems known to a person skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the license specification.

[0032] Example 1: As Figures 1 to 5 As shown, this is only one embodiment of the present invention. A fabric detection device with overload protection includes a functional part disposed between a feeding roller 9 and a receiving roller 8. The functional part includes a first roller 1, a second roller 2, and a connecting beam 3 for connecting the telescopic first roller 1 and the second roller 2. A rotating shaft 4 for driving the connecting beam 3 to rotate is disposed on the connecting beam 3. A detection beam 5 is disposed on the connecting beam 3, and a detection probe 51 is disposed on the detection beam 5.

[0033] After passing through the feeding roller 9, the fabric 7 passes through the upper side of the first roller 1 and the lower side of the second roller 2 in sequence to reach the receiving roller 8, and is tightened by rotating the shaft 4. The detection probe 51 detects the surface of the fabric 7.

[0034] The height of the first roller 1 is not less than the height of the second roller 2, and the first roller 1 is a flexible roller.

[0035] In the application, the fabric 7 is guided by the feeding roller 9 and then passes through the functional part for fabric detection, and after the detection is completed, it is guided by the collecting roller 8 for collection, that is, the fabric detection of the application is mainly located at the functional part, the functional part is arranged at the middle position between the feeding roller 9 and the collecting roller 8, the functional part includes the first roller 1 and the second roller 2 arranged in parallel with the first roller 1, the end of the first roller 1 is connected with the second roller 2 through the connecting beam 3, and the fabric 7 actually passes through the upper surface of the feeding roller 9, the upper side of the first roller 1, the lower side of the second roller 2 and the lower surface of the collecting roller 8 in sequence, so that when the fabric 7 is transmitted at the functional part, it will first reach the side of the first roller 1 away from the feeding roller 9 and then reach the side of the second roller 2 away from the collecting roller 8, and a stable transmission position is formed at the functional part, and the fabric 4 at this position can be checked.

[0036] In the structure of the application, the connecting beam 3 is provided with a rotating shaft 4 for driving the rotating shaft 4 to rotate, so that the connecting beam 3 and the first roller 1 and the second roller 2 thereon rotate around the central axis of the rotating shaft 4, and the height of the first roller 1 is not less than the height of the second roller 2, so that when the rotating shaft 4 rotates to the side of the first roller 1 away from the feeding roller 9 (at the same time, the second roller 2 is away from the collecting roller 8), the fabric between the feeding roller 9 and the collecting roller 8 is elongated, that is, it is tightened, as shown in Figure 1 On the contrary, when the rotating shaft rotates to the side of the first roller 1 close to the feeding roller 9 (at the same time, the second roller 2 is close to the collecting roller 8), the fabric between the feeding roller 9 and the collecting roller 8 is relaxed, as shown in Figure 2 For example, the rotating shaft 4 rotates clockwise, and the fabric is relaxed; on the contrary, the rotating shaft 4 rotates counterclockwise, and the fabric is tightened. Figure 1 Figure 2

[0037] In the structure of the application, the connecting beam 3 is fixedly provided with a detection beam 5, the detection beam 5 is provided with a detection probe 51, the detection probe 51 extends towards the fabric 7 between the first roller 1 and the second roller 2, and the fabric 7 passing between the first roller 1 and the second roller 2 can be detected.

[0038] It should be noted that when the fabric 7 is transmitted at the functional part, it will first reach the side of the first roller 1 away from the feeding roller 9 and then reach the side of the second roller 2 away from the collecting roller 8, and a stable transmission position is formed at the functional part, that is, it is transmitted from the left side of the first roller 1 to the right side of the second roller 2 (for example), and no matter how the rotating shaft 4 rotates, the transmission position of the fabric 7 between the first roller 1 and the second roller 2 will not change (that is, the detection probe 51 can maintain a stable angle to detect the surface of the fabric 7) under the premise of taking the detection probe 51 as a reference system, so that the detection of the detection probe 51 will not be affected. Figure 1

[0039] ​​​In the present application, the fabric 7 passes through the feeding roller 9, then passes through the upper side of the first roller 1 and the lower side of the second roller 2 in turn to reach the receiving roller 8, and the fabric 7 is tensioned by rotating the rotating shaft 4, and the detection probe 51 detects the surface of the fabric 7;

[0040] The specific detection items include:

[0041] 1. After the fabric is tensioned, the detection probe 51 can be used to detect the dirt on the surface of the fabric directly;

[0042] 2. After the fabric is tensioned to a predetermined tension, the rotating shaft 4 is reciprocally rotated in the state that the fabric 7 stops transmitting, the fabric 7 is reciprocally tensioned and loosened, and then the detection probe 51 is used to detect the fabric 7, which is used to detect the tensile strength of the fabric;

[0043] 3. The first roller 1 is a flexible roller, and the second roller 2 is a rigid roller. After the fabric is tensioned to a predetermined tension, the rotating shaft 4 is reciprocally rotated in the state that the fabric 7 keeps transmitting, the fabric 7 is reciprocally tensioned and loosened, and the fabric 7 passes through the first roller 1 under different frictional forces, and then the detection probe 51 is used to detect the fabric 7, which is used to detect the friction resistance of the printing and dyeing part of the fabric.

[0044] It should be noted that the first roller 1 is a flexible roller, so not only can the detection of the fabric 7 under the environment of the friction resistance of the fabric be simulated, but also the over-tension protection of the detection of the fabric 7 can be performed. The specific protection method is that the tension of the end of the first roller 1 is obtained, the tensioning degree of the fabric when the fabric passes through the first roller 1 is obtained, the rotating shaft 4 is controlled to rotate, so that the fabric can be ensured to be above a threshold tension when the fabric is transmitted, which is convenient for detection. At the same time, once the fabric 7 is too tensioned and reaches a dangerous tension, the rotating shaft 4 needs to be rotated to appropriately loosen the fabric 7.

[0045] The fabric detection equipment with over-tension protection can tension and loosen the fabric by the first roller and the second roller which can rotate in the position between the feeding roller and the receiving roller, so as to detect the dirt on the surface of the fabric, and the over-tension protection of the detection of the fabric can be performed by the flexible first roller in the detection process of the fabric. In addition, the compression resistance and friction resistance of the printing and dyeing on the surface of the fabric can be simulated, the detection function is multiple, and the detection effect is good.

[0046] Embodiment two, still as Figures 1 to 5 shown, is only one embodiment of the present application. Based on the embodiment one, in the fabric detection equipment with over-tension protection, the first roller 1 includes a central tensioning rope 11, an intermediate ring 12 arranged outside the central tensioning rope 11, and a rubber roller 13 arranged outside the intermediate ring 12; the number of the intermediate rings 12 is at least two, such as Figure 2 and Figure 3as shown.

[0047] That is to say, the flexible roller structure of the first roller 1 actually includes two aspects, the first aspect is that the surface structure of the first roller 1 is the rubber roller 13 which has flexibility and strong friction, and the second aspect is that the inside of the first roller 1 is actually the center pull rope 11 which is a flexible member and can be appropriately bent, so that the plurality of intermediate rings 12 are not coaxially arranged, at this time, the rubber roller 13 will be deformed to adapt to the curved structure of the first roller 1.

[0048] The connecting beam 3 is provided with a take-up drum 31 for tightening and loosening the center pull rope 11, and the take-up drum 31 is provided with a sensor for sensing the tension of the center pull rope 11, and the take-up drum 31 is electrically connected with the sensor. The sensor can obtain the tension of the center pull rope 11 at the take-up drum 31, that is, the tensioning degree when the fabric 7 passes through the first roller 1. Once the tensioning degree is too high, the take-up drum 31 loosens the rope so that the center pull rope 11 becomes longer, and then the first roller 1 is appropriately close to the first roller 2 under pressure, thereby avoiding damage to the fabric 7 due to excessive force.

[0049] In addition, when the fabric 7 passes through the first roller 1, the tensioning degree generated at the fabric 7 corresponds to the sensor reading. As long as the sensor reading is below the pressure value corresponding to the dangerous tensioning degree, the fabric 7 will not be damaged due to excessive force.

[0050] In the present application, the driving motor of the rotating shaft 4 is electrically connected with the sensor. Before the fabric 7 starts to be transmitted, the driving motor drives the rotating shaft 4 to rotate counterclockwise, so that the fabric is tensioned. At this time, the sensor reading is obtained, so as to control the fabric 7 to reach the threshold tensioning degree, thereby facilitating the detection of the fabric 7 by the detection probe 51.

[0051] In addition, in the present application, if it is necessary to increase the friction effect of the first roller 1, the first roller 1 can be arranged as a non-rotating roller body. At this time, the center pull rope 11 can be two or more, that is, a plurality of pull ropes 11 simultaneously string the plurality of intermediate rings 12 in sequence, and the rubber roller 13 is sleeved outside the intermediate ring 12.

[0052] It should be noted that the center pull rope 11 does not necessarily locate at the center of the first roller 1, but only means that the center pull rope 11 is located inside the intermediate ring 12. When there are two or more center pull ropes 11, the center pull ropes 11 are uniformly located around the center of the intermediate ring 12. Moreover, the intermediate ring 12 does not necessarily have a ring structure, but only means that the intermediate ring 12 is a cylindrical structure and has a perforation on the inner side for facilitating the center pull rope 11 to pass through. When there are two or more center pull ropes 11, the intermediate ring 12 has a plurality of perforations inside.

[0053] Embodiment three, still as Figures 1 to 5As shown, only one embodiment of the present application, on the basis of any of the above embodiments, in a fabric detection device with over-force protection, the number of connecting beams 3 is two, and two connecting beams 3 are connected to the two ends of the first roller 1 and the second roller 2 respectively, then the fabric 7 will inevitably pass between the two connecting beams 3, and will pass from one side of the connecting beam 3 to the other side of the connecting beam 3.

[0054] Here, the detection beam 5 is arranged in parallel with the second roller 2, and the two ends of the detection beam 5 are connected with the connecting beam 3 respectively, and the number of detection probes 51 is at least one.

[0055] And the number of detection beams 5 is two, and two detection beams 5 are arranged on both sides of the connecting beam 3, so that the detection probes 51 on the two detection beams 5 are used for detecting the two sides of the fabric 7 respectively.

[0056] As one of the embodiments of the present application, the connecting beam 3 is provided with a telescopic rod for driving the first roller 1 to approach and move away from the second roller 2, for controlling the initial position of the first roller 1 and the second roller 2, facilitating the fabric 7 with different flexibility to pass between the first roller 1 and the second roller 2.

[0057] As one of the embodiments of the present application, the shaft 4 is located between the feeding roller 9 and the receiving roller 8, and the central axis of the shaft 4, the central axis of the feeding roller 9 and the central axis of the receiving roller 8 are located on the same plane; similarly, the shaft 4 is located between the first roller 1 and the second roller 2, and the central axis of the shaft 4, the central axis of the first roller 1 and the central axis of the second roller 2 are located on the same plane.

[0058] In the present application, the second roller 2 is a rigid roller, which comprises a roller shaft 21 and a rotating cylinder 22 arranged on the roller shaft 21.

[0059] Finally, the connecting beam 3 is an integral high-strength alloy part.

[0060] The fabric detection device with over-force protection of the present application sets the first roller and the second roller with rotatable position between the feeding roller and the receiving roller, tightens and loosens the fabric, detects the dirt on the surface of the fabric, protects the fabric during the detection process by the flexible first roller, and can also simulate the pressure and friction resistance of the fabric surface printing, so the detection function is multiple and the detection effect is good.

[0061] The present application is not limited to the above specific embodiments, and the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made according to the technical essence of the present application to the above embodiments shall be included in the protection scope of the present application.
