Description

Technical Field

[0001] The utility model belongs to the technical field of fabric processing, and in particular relates to a rolling tension adjustment device for automobile interior fabric. Background Art

[0002] Car interior fabrics are generally used to make seat cushions, seat covers, ceilings, floor mats, etc. According to the characteristics of the fabrics, cotton, wool, chemical fiber, etc. can be selected. Car interior fabrics can be divided into pure cotton fabrics, pure wool fabrics, chemical fiber fabrics and blended fabrics according to the composition of their raw materials.

[0003] During the processing of automobile interior fabrics, a winding mechanism is needed to wind them up. During the winding process, the reel formed gradually becomes thicker, and the length of the fabric wound up by one circle also becomes longer. Therefore, it is necessary to change the winding speed in real time to ensure that the fabric is neither too loose nor too tight during the winding process, because too loose may cause wrinkles in the wound fabric, and too tight may damage the fabric. However, in the traditional winding method, the winding speed is difficult to control, and it is very easy to be too loose or too tight. In order to solve the above problems, a winding tension adjustment device for automobile interior fabrics is provided.

[0004] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Utility Model Content

[0005] In order to solve the above problems, the purpose of the utility model is to provide a device for adjusting the tension of automobile interior fabric winding. By setting the adjustment component, when winding the fabric, as long as the distance between the fabric and the connecting strip is greater than h2 and less than h1, the fabric can be kept in a taut state and not over-tightened. When an over-tightened state or a loose state occurs, the rotation speed of the servo motor can be detected and adjusted in time, and the fabric can be adjusted to a taut state in time to avoid damaging the fabric when winding it or wrinkles when winding it.

[0006] To achieve the above-mentioned purpose, the utility model proposes a winding tension adjustment device for automobile interior fabric, the tension adjustment device comprising a winding platform and a winding drum for winding the fabric, symmetrically distributed vertical plates are fixed above the winding platform, and a rotating mechanism for controlling the rotation of the winding drum is installed on the vertical plates. The two rotating mechanisms are respectively clamped at both ends of the winding drum, and an adjustment component for adjusting the tension of the fabric is provided between the two vertical plates.

[0007] The adjustment component includes two vertical slide rails, which are respectively opened on two vertical plates. Sliding blocks are slidably arranged in the vertical slide rails. A fixed shaft is connected between the two sliding blocks. The fixed shaft, guide roller and winding drum are parallel to each other. A vertical spring is fixedly connected between the sliding block and the vertical slide rails.

[0008] Further, a connecting bar is fixedly connected between the two vertical plates, and a distance sensor is fixed below the connecting bar. The distance sensor is located directly above the fixed shaft.

[0009] Further, clamping grooves are provided at both ends of the winding drum.

[0010] Further, the rotating mechanism includes a first cylinder vertically fixed on the vertical plate. The output shaft of the first cylinder penetrates through the vertical plate and is fixed with a driving box. A servo motor is fixed inside the driving box. The output shaft of the servo motor penetrates through the side plate on the side of the driving box away from the first cylinder and is fixed with a limiting plate. A clamping block matching the clamping groove is fixed on the limiting plate, and the two clamping blocks correspond to each other.

[0011] Further, the distance sensor is used for the distance between the fabric directly below it and the connecting bar.

[0012] Further, a vertical second cylinder is fixed above the vertical plate, and the second cylinder is used to drive the sliding block to slide.

[0013] Further, a guiding roller is rotatably arranged between the two vertical plates.

[0014] Further, the guiding roller is located between the adjusting assembly and the winding drum.

Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more solutions or examples.

[0026] An embodiment of the utility model provides a device for adjusting the winding and tension of an automotive interior fabric. The tension adjusting device includes a winding platform 1 and a winding drum 3 for winding the fabric. As Figure 1 shown, (the fabric shown in the specification drawings is a broken structure, one end of which is wound by the winding drum 3, and the other end is released through other mechanisms in the fabric processing, not shown in the figure) symmetrically distributed vertical plates 11 are fixed above the winding platform 1. A rotating mechanism 2 for controlling the rotation of the winding drum 3 is installed on the vertical plates 11. The two rotating mechanisms 2 are respectively stuck at both ends of the winding drum 3. An adjusting component 4 for adjusting the fabric tension is provided between the two vertical plates 11. A guide roller 5 is rotatably arranged between the two vertical plates 11. The guide roller 5 is located between the adjusting component 4 and the winding drum 3.

[0027] Card slots 31 are provided at both ends of the winding drum 3. As Figure 2 shown.

[0028] The rotating mechanism 2 includes a first cylinder 21 vertically fixed on the vertical plate 11. The output shaft of the first cylinder 21 penetrates the vertical plate 11 and is fixed with a driving box 22. A servo motor 23 is fixed in the driving box 22. The output shaft of the servo motor 23 penetrates the side plate on the side of the driving box 22 away from the first cylinder 21 and is fixed with a limiting plate 24. A clamping block 25 matching the card slot 31 is fixed on the limiting plate 24. The two clamping blocks 25 correspond to each other.

[0029] The adjusting component 4 includes two vertical sliding rails 41. As Figure 3 shown, the two vertical sliding rails 41 are respectively arranged on the two vertical plates 11. A sliding block 42 is slidably arranged in the vertical sliding rail 41. A fixed shaft 44 is connected between the two sliding blocks 42. The fixed shaft 44, the guide roller 5 and the winding drum 3 are parallel to each other. A vertical spring 43 is fixedly connected between the sliding block 42 and the vertical sliding rail 41. A connecting bar 45 is fixedly connected between the two vertical plates 11. A distance sensor 46 is fixed below the connecting bar 45. The distance sensor 46 is located directly above the fixed shaft 44. The distance sensor 46 is used to measure the distance between the fabric directly below it and the connecting bar 45. The distance sensor 46 is electrically connected to a preset control system.

[0030] A vertical second cylinder 47 is fixed above the vertical plate 11. The second cylinder 47 is used to drive the sliding block 42 to slide. The output shaft of the second cylinder 47 is not connected to the sliding block 42.

[0031] In use, after the fabric is released, it bypasses from above the fixed shaft 44 and below the guide roller 5 in sequence and then is connected to the winding drum 3. By extending the second cylinder 47, the slider 42 is controlled to move downward, so that the fixed shaft 44 is disengaged from the fabric. By flattening the fabric, the distance between the fabric and the connecting strip 45 in the flattened state is detected by activating the distance sensor 46, denoted as h0. The distance between the fabric and the connecting strip 45 in the natural state of the spring 43 is denoted as h1. When winding the fabric, the distance between the fabric and the connecting strip 45 is h. Then when h1>h>h2, it indicates that there is an appropriate pressure between the fabric and the connecting strip 45, which means the fabric is in a tensioned state. When h = h1, it indicates that there is no pressure between the fabric and the connecting strip 45, which means the fabric is likely to be in a slack state, and the rotational speed of the servo motor 23 should be adjusted and increased in time to adjust the fabric to a tensioned state. When h = h2, it indicates that the pressure between the fabric and the connecting strip 45 is very large, which means the fabric is likely to be in an over-tensioned state, and the rotational speed of the servo motor 23 should be reduced in time to adjust the fabric to a tensioned state.

Each embodiment focuses on the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and for the relevant parts, reference can be made to the partial description of the method embodiment.

For those skilled in the art, various modifications and changes can be made to the present invention.
