[0002] Fabric weight is an important technical indicator for evaluating fabrics. It will affect the thickness, feel and strength of the fabric. Therefore, it is usually necessary to test the fabric weight before large-scale production.

[0003] At present, when testing the weight of fabrics on the market, the fabrics need to be laid flat and a certain area of ​​fabrics need to be cut, and then the fabrics need to be weighed using an electronic weight scale, and finally the weight data of the fabrics are converted. However, when testing the weight of fabrics in the above way, the matching cutting tools must be used, and the fabrics need to be cut every time the weight is tested, which makes the weight testing operation more cumbersome; and in other cases, the customer only provides a small area of ​​sample fabrics, which makes the cutting of fabrics more difficult, and once the cutting is deviated, it will affect the accuracy of fabric testing, and then affect the subsequent production of fabrics.

[0031] like Figures 1 to 8 As shown, a fabric weight meter includes a box body 1, in which a weighing mechanism 2 and an image acquisition mechanism 3 are arranged. Specifically, a chamber 11 is opened inside the box body 1, and the image acquisition mechanism 3 and the weighing mechanism 2 are installed in the chamber 11 up and down. The box body 1 can also be provided with a rotatably installed door panel to open or close the chamber 11.

[0032] The weighing mechanism 2 includes a weight sensor 21 and a back plate 22 mounted on the weight sensor 21 . The back plate 22 is used to place the fabric 5 to be tested, and the weight sensor 21 is used to measure the weight of the fabric 5 .

[0033] refer to Figure 1 , Figure 2 As shown, the image sensor 36 of the image acquisition mechanism 3 is located above the back plate 22. The image acquisition mechanism 3 includes a screw rod 32 and a slide rod 34 which are arranged perpendicular to each other. The slide rod 34 is mounted on the screw rod 32. The image sensor 36 is mounted on the slide rod 34 so that the image sensor 36 can be adjusted in a horizontal plane in a forward, backward, left, and right manner (in degrees). Figure 1As an example, the image sensor 36 can be moved to the position just above the fabric 5 to be detected for shooting, so that the area measurement of the fabric 5 is more accurate.

[0034] Specifically, a driving member 31 is installed in the chamber 11. The driving member 31 can be a motor. The driving member 31 drives the screw rod 32 to rotate. A guide rod 33 arranged parallel to the screw rod 32 is also installed in the chamber 11. The two ends of the slide rod 34 are respectively installed on the screw rod 32 and the guide rod 33. The screw rod 32 rotates to drive the slide rod 34 to move forward and backward, that is, drives the image sensor 36 installed on the slide rod 34 to move forward and backward.

[0035] A slider 35 is slidably mounted on the slide bar 34 , and the image sensor 36 is fixedly mounted on the slider 35 and can shoot downward the fabric 5 placed on the back plate 22 . The slider 35 can be displaced along the length direction of the slide bar 34 to drive the image sensor 36 to move left and right.

[0036] An obliquely mounted mounting plate 12 is disposed in the box body 1 , and a downwardly disposed lamp body 13 is mounted on the mounting plate 12 . The lamp body 13 illuminates the interior of the box body 1 to enhance the brightness of the image captured by the image sensor 36 .

[0037] By cooperating with the screw rod 32 and the slider 35, the image sensor 36 can be displaced to any position above the back plate 22 for shooting, so as to calculate the area of ​​the fabric 5 to be detected, so that there is no need to cut the fabric 5, thereby avoiding the waste of the fabric 5. It is also possible to calculate the area of ​​the fabric 5 with a smaller area or even irregular contours, so as to facilitate the subsequent gram weight detection operation.

[0038] refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, the weight sensor 21 is provided with a plurality of wires 26 capable of downwardly abutting against the back plate 22. Specifically, a vertically arranged limit rod 23 is installed on the weight sensor 21, and the limit rod 23 is distributed at the four corners of the upper end surface of the sensor 21. A bracket 24 is provided on the outer periphery of the back plate 22, and the bracket 24 is a hollow frame structure with a hollow middle portion. The back plate 22 and the bracket 24 are distributed at intervals, and the bracket 24 is provided with a through hole 241 corresponding to the position of the limit rod 23. The through hole 241 cooperates with the limit rod 23 so that the bracket 24 can be slid up and down and installed on the limit rod 23.

[0039] refer to Figure 4 , Figure 5As shown, the bracket 24 is provided with slide grooves 242 which are distributed parallel to each other, and the connecting block 25 is slidably installed in the slide groove 242. The bracket 24 is provided with a connecting block 25 which can slide horizontally, that is, the connecting block 25 can slide along the length direction of the slide groove 242. The wire 26 is installed on two oppositely arranged connecting blocks 25. The wire 26 is a transparent wire. In order to reduce the interference of the wire 26 on the area measurement of the image acquisition mechanism 3, the diameter of the wire 26 can be designed to be less than 1MM.

[0040] refer to Figure 3 As shown, the bracket 24 slides downward until the wire 26 abuts against the back plate 22 , at which time the weight measured by the weight sensor 21 is reset; after the fabric 5 to be tested is placed on the back plate 22 , the weight measured by the weight sensor 21 is the actual weight of the fabric 5 .

[0041] The weight of the fabric 5 is then measured by the weight sensor 21, and the gram weight data of the fabric 5 is calculated by a formula, so that the detection of the gram weight of the fabric 5 is more convenient and accurate.

[0042] refer to Figure 5 , Figure 6 As shown, a connecting column 251 is detachably mounted on the upper portion of the connecting block 25 , and a plurality of ridges 252 are arranged on the outer periphery of the connecting column 251 . The connecting column 251 and the connecting block 25 are screwed together by threads.

The connecting column 251 passes through the bracket 24 upward through the second slide groove 243. The connecting column 251 is abutted and installed in the second slide groove 243. The connecting column 251 can be displaced along the length direction of the second slide groove 243, that is, the connecting column 251 is displaced to drive the connecting block 25 to move synchronously, thereby driving the wire 26 to move.

[0044] refer to Figure 7 , Figure 8 As shown, Figure 7 The arrow in the figure is the displacement direction of the thread 26. The thread 26 first presses down the fabric 5 placed on the back plate 22, and then the fabric 5 to be tested is smoothed and flattened by the displacement thread 26 (refer to Figure 8 The state of the fabric) is used to ensure the accuracy of the fabric 5 area measurement and gram weight detection, and to avoid the situation where the fabric 5 is affected by the uneven folds of the fabric 5, which may affect the fabric 5 shooting and area calculation, resulting in deviations in the fabric 5 area measurement data and inaccurate gram weight detection.

[0045] A control panel 4 is installed on the upper part of the box body 1, and a display screen 41, a connection hole 43 and a plurality of buttons 42 are installed on the control panel 4. The display screen 41 is used to display the gram weight data of the fabric 5 detected each time, and the connection hole 43 can be used to connect a data cable to derive the detection data of the gram weight of the fabric 5.

[0046] The buttons 42 include a start button, an off button, a reset button, and a detection button. The start button is used to start the device, the off button is used to shut down the device, the reset button is used to reset the weight measured by the weight sensor 21 and reset the detected weight to zero, and the detection button is used to calculate the area of ​​the fabric 5 calculated by the image sensor 36 and the weight of the fabric 5 measured by the reset weight sensor 21 to display the gram weight detection data on the display screen 41.
