[0002] In industrial production, many products require online real-time width measurement. The grating width gauge uses measuring grating technology. By placing two sets of grating width gauges at the edge change range at both ends of the material width, the changing dynamics of the two edges are monitored in real time, and the edge position information of the material is converted into a signal and transmitted to the calculation processor. By calculating the edge position information value and the central fixed distance value, the real-time width of the real-time product material is measured and displayed on the electronic screen. By setting the alarm threshold in the processor, the required signals such as alarm and shutdown can be output according to customer requirements.

[0003] The above-mentioned and existing technologies have the following defects: when using a grating width gauge to measure fabric, since the installation position of the grating width gauge is fixed, when measuring fabrics of different widths, it is difficult to adjust the distance between the grating width gauges according to the width of the fabric, thereby reducing the flexibility when using the grating width gauge.

[0004] Therefore, a grating width measurement device is proposed. Utility Model Content

[0026] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] like Figures 1-4 As shown, the utility model provides a grating width measuring device, including a mounting plate 1 and a grating instrument 2, an adjusting structure 3 is provided on the surface of the mounting plate 1, and an auxiliary structure 4 is provided on the surface of the mounting plate 1.

[0029] The following describes in detail the specific settings and functions of the regulating structure 3 and the auxiliary structure 4.

[0030] like Figure 2 and Figure 3As shown, the adjustment structure 3 includes a servo motor 31, which is fixedly connected to the mounting plate 1, and a screw 32 is fixedly connected to the output end of the servo motor 31. A support plate 35 is fixedly connected to the surface of the mounting plate 1, and the screw 32 is rotatably connected to the support plate 35. The arc surface of the screw 32 is provided with a threaded groove in opposite directions, and the arc surface of the screw 32 is threadedly connected to two connecting plates 33. The surface of the connecting plate 33 is fixedly connected to a rectangular plate 34, and the rectangular plate 34 is fixedly connected to the grating instrument 2. The surface of the mounting plate 1 is fixedly connected to a scale plate 36, and the surface of the connecting plate 33 is fixedly connected to a pointer 37. The movement of the connecting plate 33 will drive the pointer 37 to move. The cooperation between the pointer 37 and the scale plate 36 can facilitate the grasp of the moving distance of the grating instrument 2, thereby facilitating the calculation of the distance between the two grating instruments 2. The surface of the connecting plate 33 is rotatably connected to a ball 38, and the ball 38 rests on the surface of the mounting plate 1. The ball 38 can reduce the friction between the connecting plate 33 and the mounting plate 1.

[0031] like Figure 2 and Figure 4 As shown, the auxiliary structure 4 includes four strip plates 41, which are fixedly connected to the mounting plate 1, and the four strip plates 41 are grouped in pairs. The surfaces of the two groups of strip plates 41 are rotatably connected to rollers 42, and the arc surface of the roller 42 is slidably connected to a retaining ring 43. The surface of the retaining ring 43 is fixedly connected to a circular ring 44, and the inner thread of the circular ring 44 is connected to a bolt 45. The retaining ring 43 can limit the movement range of the fabric to prevent the fabric from deviating and affecting the accuracy of the measurement result. The end of the bolt 45 close to the roller 42 is rotatably connected to a circular plate 46, and the surface of the circular plate 46 is fixedly connected to a friction pad 47. The friction pad 47 is a rubber pad, and the friction pad 47 increases the friction between the bolt 45 and the roller 42.

[0032] The overall working principle is that before the cloth needs to be measured, the cloth is passed around the two rollers 42. The rollers 42 can adjust the movement angle of the cloth to facilitate the cloth to pass through the grating meter 2 and avoid the cloth from contacting the grating meter 2. Then the cloth passes through the grating meter 2 in the horizontal direction, and then the retaining ring 43 is slid along the arc surface of the roller 42. When the retaining ring 43 slides to a suitable position, the bolt 45 is turned. The bolt 45 will drive the circular plate 46 to move with the help of the thread. The movement of the circular plate 46 will make the friction pad 47 press against the arc surface of the roller 42. The friction pad 47 increases the friction between the bolt 45 and the roller 42, thereby limiting the position of the retaining ring 43. The retaining ring 43 can limit the movement range of the cloth to avoid the situation where the cloth offset affects the accuracy of the measurement result. Then the grating meter 2 is turned on and the grating meter 2 can measure the cloth. The length of the fabric at the grating meter 2 is obtained. On this basis, the width of the fabric can be calculated in combination with the distance between the two grating meters 2. When fabrics of different widths need to be measured, the servo motor 31 is turned on. The rotation of the output end of the servo motor 31 will drive the screw 32 to rotate. The screw 32 will drive the connecting plate 33 to move with the help of the thread. The connecting plate 33 will drive the ball 38 to roll along the surface of the mounting plate 1. The ball 38 can reduce the friction between the connecting plate 33 and the mounting plate 1. The rectangular plate 34 follows the movement of the connecting plate 33 to drive the grating meter 2 to move, thereby adjusting the distance between the grating meters 2. When fabrics of different widths need to be measured, the movement of the connecting plate 33 will drive the pointer 37 to move. The pointer 37 cooperates with the scale plate 36 to easily grasp the moving distance of the grating meter 2, thereby facilitating the calculation of the distance between the two grating meters 2.

[0033] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
