Description

Technical Field

[0001] This utility model relates to the field of dynamic error compensation technology for fabric weight, and in particular to a dynamic error compensation mechanism for fabric weight detection. Background Technology

[0002] Fabric weight per unit area refers to the weight of fabric per unit area. During fabric weight measurement, especially for fabrics with elasticity, changes in tension directly affect the measurement results. When tension increases, the fabric is stretched, the spacing between fibers decreases, and the number of fibers per unit volume increases, resulting in a higher weight reading. Conversely, when tension decreases, the fabric is in a more relaxed state, the fiber spacing increases, and the number of fibers per unit volume decreases, leading to a lower weight measurement. In existing technologies, real-time tension adjustment of the conveying fabric can easily cause the fabric to jump or loosen during operation, reducing the accuracy and stability of weight measurement and affecting the dynamic error compensation effect. Therefore, this application proposes a dynamic error compensation mechanism for fabric weight measurement. Utility Model Content

[0025] Example 1

[0026] like Figure 1 As shown, the fabric weight detection dynamic error compensation mechanism proposed in this utility model includes a base 1, with support plates 5 fixedly connected to both sides of the base 1. The support plates 5 on both sides are firmly fixed to the base 1 to ensure the verticality and parallelism of the support plates 5. A tension adjustment component 2 and two sets of conveying components 3 are arranged between the two support plates 5. The tension adjustment component 2 is located between the two sets of conveying components 3. The tension adjustment component 2 will not affect the fabric conveying, and at the same time, it facilitates the real-time adjustment of the fabric tension when the conveying components 3 convey the fabric, ensuring that the fabric maintains a suitable tension during the detection process and reducing the weight detection error caused by tension changes.

[0027] And, as Figure 3 As shown, the tension adjustment assembly 2 includes a tension roller 21 rotatably connected between two support plates 5. The tension roller 21 is a driven roller, and each of the two support plates 5 has a fixed groove 28 on one side. The two grooves 28 are located on the outer wall of the support plate 5, which can avoid affecting the fabric conveying. The tension roller 21 is slidably connected between the two grooves 28. The tension roller 21 adjusts the tension by moving up and down. The support plate 5 has an opening 51, which passes through the support plate 5 and is connected to the groove 28, so that the tension roller 21 can move between the openings 51.

[0028] In addition, such as Figure 2 and Figure 3As shown, each of the two grooves 28 is rotatably connected to a connecting rod 23, and each of the two connecting rods 23 is fixed above a screw 231. Each of the two screws 231 is slidably connected to a slider 22. The end of the tension roller 21 passes through the opening 51 and is rotatably connected between the two sliders 22. The sliders 22 are slidably connected within the grooves 28. A limit block 24 is fixedly connected at the junction of the connecting rod 23 and the screw 231. The limit block 24 can limit the slider 22, preventing it from separating from the screw 231. The tension adjustment assembly 2 also includes a protective shell 29. Gears 25 are rotatably connected to both ends inside the protective shell 29. A toothed belt 26 meshes with the outer sides of the two gears 25. A motor 27 is fixed to one side of the bottom of the protective shell 29. The output end of the motor 27 extends into the protective shell 29 and meshes with a gear 26. 5. A fixed connection is made, and two gears 25 are respectively fixedly connected to the bottom of two connecting rods 23. Motor 27 drives the gear 25 fixedly connected to its output end to rotate. The gear 25 drives the other gear 25 to rotate through the toothed belt 26. Since the two gears 25 are respectively fixed to the bottom of the two connecting rods 23, the two connecting rods 23 rotate synchronously, and drive the two screws 231 above them to rotate accordingly. Then, the sliders on both sides slide synchronously and drive the tension roller 21 to move, adjusting the tension. When the fabric weight is too low, the motor 27 drives the two screws 231 to rotate in the forward direction, causing the tension roller to move upward and appropriately increase the tension. Conversely, when the fabric weight is too high, the motor 27 drives the two screws 231 to rotate in the reverse direction, causing the tension roller to move downward and appropriately decrease the tension.

[0029] It should be added that, such as Figure 3 and Figure 4 As shown, a support frame 7 is fixedly connected between the tops of the two chutes 28, and an image sensor 8 is fixedly connected to the bottom of the support frame 7. The image sensor 8 is located directly above the tension roller 21. A distance sensor 6 is fixedly connected to the top of the protective shell 29 and is located directly below the tension roller 21. During the fabric conveying process, the image sensor 8 collects the surface image of the fabric on the tension roller 21 in real time. By analyzing the image, information such as the texture and density of the fabric is obtained. The distance sensor 6 monitors the change in distance between the tension roller 21 and the fabric in real time. Together with the image sensor 8, it is easy to judge the tension state of the fabric. The distance difference detected by the distance sensor 6 is proportional to the tension of the fabric. The greater the distance difference, the greater the tension. During the entire fabric conveying process, the image sensor 8 and the distance sensor 6 continuously collect data. The position of the tension roller 21 and the tension of the fabric can be continuously adjusted according to the real-time data to achieve continuous compensation for the dynamic error of the fabric weight detection and ensure the accuracy of the detection results.

[0030] Example 2

[0031] like Figure 1 and Figure 5As shown, based on Embodiment 1, a pressure roller assembly 4 is provided above the tension roller 21. The pressure roller assembly 4 includes guide grooves 44 respectively opened in the middle of two openings 51. Guide plates 43 are slidably connected in both guide grooves 44. Connecting plate 1 42 and connecting plate 2 45 are rotatably connected to one side of each of the two guide plates 43. Pressure rollers 41 are rotatably connected between the two connecting plates 1 42 and between the two connecting plates 2 45. The pressure rollers 41 are in contact with the upper part of the tension roller 21. During the adjustment of the position of the tension roller 21, the pressure rollers 41 always keep in contact with the fabric above the tension roller 21 through the sliding of the guide plates 43 in the guide grooves 44 and the rotation of the connecting plates 1 42 and connecting plates 2 45, ensuring that the fabric is in close contact with the surface of the tension roller 21 and improving the accuracy of weight detection.

[0032] The conveying assembly 3 includes two conveying rollers 34 rotatably connected between two support plates 5. One end of each conveying roller 34 passes through the support plate 5 and is fixedly connected to a sprocket 31. A chain 32 is meshed with the outer side of the two sprockets 31. A motor 33 is connected to the outer side of one sprocket 31. When the fabric is conveyed, the motor 33 is started, and the motor 33 drives the sprocket 31 connected to its output end to rotate. The sprocket 31 drives the other sprocket 31 to rotate through the chain 32, so that the two conveying rollers 34 rotate synchronously and convey the fabric smoothly.

[0033] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
