Description

Technical Field

[0001] The invention relates to the field of product sealing equipment, in particular to a sealing machine. Background Art

[0002] Labels are paper or synthetic materials used to identify, describe or classify items, documents, etc. Labels usually contain text, barcodes, QR codes, images and other information to facilitate identification, management and tracking of items. With the development of the economy, labels are widely used on commodities, which has led to the rapid development of the label printing industry. The production of labels is inseparable from label printers. Label printers are a device specifically used to print labels, which can print text, barcodes, QR codes and images.

[0003] The packaging box or the exterior of the product is labeled. Paper labels and plastic labels are currently produced as rolls of finished products. When used, they are peeled off by a sealing machine and attached to the surface of the product packaging box under the action of the sealing machine. In this process, the rolled labels are rotated on the rotating shaft or paper tray of the sealing machine, and then peeled off one by one and sealed. This has at least the following problems: First, after the existing sealing machine peels off the label, the base paper needs to be recycled first, and the work of collecting the base paper is also completed by a reel. During the reeling process of the existing reel, it is not convenient to fix the base paper on the reel at the beginning, and it is not convenient to take the reeled base paper off the reel when a lot of base paper is reeled. If the base paper is pressed by rotating the reel, this operation will easily cause the reel to rotate with the rotation process, and it will easily turn in the wrong direction, which is inconvenient to fix the base paper at the beginning and take it out afterwards. Second, the existing sealing machine cannot effectively control the tension, and the tension is uneven during use; Third, the existing sealing machines all convey new labels forward by pulling the base paper. However, in the process of pulling the base paper, as the rolled base paper becomes thicker and thicker, the length of the base paper pulled by each rotation of the reel is different, and it is inconvenient to accurately control the length of the paper pulled. In addition, as the base paper becomes thicker and thicker, the torque of the reel that drives the base paper to be rolled up also changes from time to time, which makes the load on the motor unstable and easily causes the motor to age. Fourthly, in the process of peeling off the label for sealing in the existing sealing machine, the label will be scratched by the paper outlet and / or the peeling plate, resulting in scratches on the surface of the label paper; Fifth, the existing sealing machine has a paper pressing wheel that is not easy to insert label paper, and only has an automatic working mode but no manual working mode. At the same time, the operating surface is placed vertically, which is inconvenient to operate. Summary of the invention
