The winding motor 33 is fixed on the winding motor bracket 32 by bolts, and the winding motor 33 is connected to the winding shaft 30 through a coupling.

[0096] When the present utility model is in use, workers select several rolls from the same batch of printing cloth purchased as printing cloth samples for density detection.

[0097] For example, when selecting the printing cloth sample of batch A, 20 rolls of printing cloth are selected as samples, numbered respectively, a barcode label is generated and fixed at the corner of the sample cloth roll.

[0098] During detection, the worker searches for the corresponding printing cloth density information in the storage unit according to the type of printing plate for which the sample needs to be printed. After the printing cloth density information is retrieved and obtained by the detection unit, the worker scans the barcode label on the printing cloth sample with a barcode scanner to obtain the corresponding sample cloth batch number.

[0099] The printing cloth is placed in the unwinding unit. After the printing cloth sample is pulled flat by several rollers in the unwinding unit, it is conveyed to the transfer platform. After the CCD camera obtains the image of the printing cloth sample, it starts to detect the density of the printing cloth sample, generates a woven density detection line graph, obtains the actual density of the printing cloth sample, and matches it with the initially found printing cloth density information.

[0100] Regardless of whether they match or not, the reminder unit will output the matching result and display a prompt to inform the worker of the result of the printing cloth sample.

[0101] The receiving unit winds up the detected printing cloth sample again during the detection process so that the worker can remove it.

[0102] The present utility model combines the upper computer and the lower computer. During the printing cloth detection process, machine vision detection is combined with the unwinding and winding processes supplemented by the data of the printing plate, which is convenient for the factory to detect the density of the printing cloth during mass production, so as to improve the work efficiency of the printing factory. It does not require the consumption of printing materials in the early stage of printing. Only the quality of the printing cloth sample needs to be detected in the early stage, thereby reducing printing consumables and printing costs.

[0103] During the unwinding process, appropriately match a suitable roll system structure, and supplement the tension roller to adjust the tension of the printed fabric to prevent wrinkles from appearing on the printed fabric during the density detection process, thereby improving the detection efficiency of the printed fabric.

[0104] Supplement the pressing mechanism of the printed fabric to prevent the fabric from sliding during transmission, resulting in unclear images captured by the CCD camera, and improve the accuracy of the detection results of the printed fabric density. Supplement the winding mechanism to reduce the workload of workers for winding.

[0105] Specifically, in this embodiment, the printed fabric density detection device further includes a motor encoder and a push switch;

[0106] The motor encoder includes an unwinding motor encoder connected to the unwinding motor 24, a winding motor encoder connected to the winding motor 33, and a conveying motor encoder connected to the conveying motor of the conveying platform 10. The unwinding motor encoder adjusts the unwinding speed of the unwinding motor, the winding motor encoder adjusts the winding speed of the winding motor, and the conveying motor encoder adjusts the conveying speed of the printed fabric sample;

[0107] The push switch includes an unwinding switch connected to the unwinding motor 24, a winding switch connected to the winding motor 33, and a conveying switch connected to the conveying motor of the conveying platform 10. The unwinding switch adjusts the start and stop of the unwinding motor, the winding switch adjusts the start and stop of the winding motor, and the conveying switch adjusts the start and stop of the conveying motor.

[0108] The utility model adjusts each unit of the printed fabric density detection device separately by setting a motor encoder and a push switch. At the same time, the push-type switch can timely stop the clicks of each unit's operation to ensure the safety of the detection process.

[0109] The above are only the preferred embodiments of the utility model and are not intended to limit the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model shall be included within the protection scope of the utility model.
