Description
TECHNICAL FIELD
[0001] The utility model relates to the field of label winding and unwinding, in particular to a label winding and unwinding device. BACKGROUND
[0002] A label is a paper or synthetic material product used to identify, describe, or classify items, documents, etc. A label usually contains text, barcodes, QR codes, pictures, etc. information to facilitate identification, management, and tracking of items. With the development of the economy, the widespread application of labels on commodities has driven the rapid development of the label printing industry. The production of labels cannot be separated from label printers, which are devices specifically designed for printing labels and can print text, barcodes, QR codes, and images.
[0003] Currently, when a large number of products need to be produced, a large number of labels are also needed. These labels usually need to be printed in advance and wound up by a label rewinder for storage, and can be directly attached to the product during use. However, there are two problems in the entire process:
[0004] 1. When printing (producing) labels, the printed labels need to be wound up using a label rewinder. However, the normal printing speed of the printer is unstable, and the winding speed of the label rewinder is also synchronized with the printer. Therefore, when winding up the printed labels, the winding speed cannot be synchronized with the printing speed of the printer. At this time, when the winding speed is higher than the printing speed, the label backing paper will be pulled, which may cause damage to the motor and may also cause the label paper to be pulled off, resulting in winding failure. If the winding speed is slow, the printed labels may not be wound up in time and may accumulate. To solve this problem, a start-up pressure rod is installed on the label rewinder, and the backing paper is wound around the bottom of the start-up pressure rod. When the printing speed of the printer is too slow, the backing paper between the label printer and the label rewinder will be pulled tight, triggering the start-up pressure rod and stopping the label rewinder. When the label printer ejects the paper, the backing paper between the label printer and the label rewinder is in a relaxed state, causing the start-up pressure rod to drop and the label rewinder to restart winding. Although this solution solves the winding problem, the paper feeding direction of the label winding is single, and in actual factory applications, the positional relationship between the label printer and the label rewinder is adjusted according to the conditions of each production workshop. If the paper feeding direction of the label winding is changed, it cannot be applied.
[0005] 2. The current label rewinder has a single function and can only achieve single winding for different styles. When the label paper needs to be released, another unwinding device needs to be replaced. SUMMARY
