Background
Fabric grammage generally refers to the weight in grams per square meter of fabric. The gram weight of the fabric is an important index influencing the physical and mechanical properties and the wearing comfort of the fabric. Because the gram weight is changed in each process of fabric bleaching, dyeing, finishing, heat setting and the like, the gram weight of the fabric in each process can be kept stable and the product quality can be improved only by detecting the gram weight of the fabric on line in real time and guiding the finishing process to set up a processing technology.
An existing fabric gram weight online detection mechanism, such as a structure disclosed in chinese patent ZL201610267393.1, includes a frame, the frame includes an upper transverse support and a lower vertical frame located below the rear end of the upper transverse support; the lower vertical rack is sequentially provided with a tensioning roller, a cloth feeding roller and a cloth guide roller from bottom to top; the front end of the upper transverse bracket is provided with a cloth outlet roller; the cloth swinging device is positioned at the front lower part of the upper transverse bracket and is connected with the front end of the upper transverse bracket through the swinging bracket; a high-precision cloth length measuring instrument is arranged above the cloth outlet roller; a high-precision cloth width measuring instrument is arranged between the cloth outlet roller and the cloth guide roller; a high-precision dynamic weighing sensor is arranged at the front lower part of the upper transverse bracket; the high-precision dynamic weighing sensor, the high-precision cloth width measuring instrument and the high-precision cloth length measuring instrument are respectively connected with a computer; the computer is positioned on the side edge of the rack; an LED display screen is further mounted on the side edge of the rack; the LED display screen is connected with a computer. However, the online detection mechanism for the gram weight of the fabric has the following disadvantages in the using process: (1) in the cloth length measurement, the cloth length is obtained by means of rolling of rollers on two sides of the length measuring instrument along with the movement of the cloth, and recording the number of rolling circles, and multiplying the number of the rolling circles by the circumference of the rollers. The roller rolls along with the movement of the cloth, and the relative sliding between the roller and the movement of the cloth cannot be ignored, particularly the relative sliding between the roller and the movement of the cloth is larger when the fabric is accelerated or decelerated; in addition, the abrasion of the roller can also influence the circumference of the roller, and the factors can influence the accuracy of the length measurement of the cloth; (2) in dynamic weighing of cloth, the weight of a scale body of a bearing system is too heavy, and when a computer instantly samples for calculation within a certain time or a certain length, the increment of the weight of the cloth is far smaller than the weight of the scale body, so that the weighing and metering precision of the cloth is greatly influenced.
In addition, the conventional fabric gram weight detection method includes that cloth is cut and sampled manually, and then the sampled cloth is weighed. The method has low working efficiency through manual detection, and the cloth is damaged after cutting and sampling, so that the waste is serious.

As a preferred embodiment of the present invention, the diameters of the first cloth guide roller, the second cloth guide roller and the third cloth guide roller are the same.
As an optimal implementation scheme of the utility model, the both ends of first fabric guide roll, second fabric guide roll and third fabric guide roll all are provided with the bearing frame, weighing sensor warp the both ends at first fabric guide roll, second fabric guide roll, third fabric guide roll are installed to the bearing frame.
In the present invention, the central processing unit is preferably a digital controller with a human-computer interface, or an embedded control system, or an industrial personal computer.
After the structure is adopted, the utility model discloses following beneficial effect has:
the utility model discloses a set up first fabric guide roller, second fabric guide roller and third fabric guide roller at the fabric traffic direction, distance between first fabric guide roller and the third fabric guide roller equals the diameter of second fabric guide roller, at first fabric guide roller, second fabric guide roller, the real-time load of third fabric guide roller is installed respectively at the both ends of third fabric guide roller, then calculates the fabric area between first fabric guide roller and the third fabric guide roller according to the fabric breadth and calculates first fabric guide roller, second fabric guide roller and third fabric guide roller according to weighing sensor measured data, central processing unit obtains the dynamic gram weight of fabric through the operation, the utility model discloses can reflect the per square meter gram weight of fabric more accurately in real time, avoid artifical work efficiency that leads to the fabric cutting sample extravagant, damage cloth cover and the drawback of fabric.
The utility model discloses the structure is simpler, and it is more simple and convenient to operate, and work efficiency is higher, guides the arrangement process to formulate processing technology through the real-time fabric grammes per square metre that records, makes in production fabric grammes per square metre remain stable, improves the product percent of pass.
