Film tension adjusting device

Abstract

The invention provides a film tension adjusting device. The film tension adjusting device comprises a feeding wheel. A tangent first pressing plate is arranged on one side of the feeding wheel, and the first pressing plate is vertically arranged on a fixing plate through a first supporting rod. The first pressing plate can rotate relative to the first supporting rod. A plurality of guiding rods are arranged below the first supporting rod. A first drive frame is arranged on the left sides of the guiding rods, a second drive frame is arranged on the right sides of the guiding rods, and the firstdrive frame and the second drive frame are driven by a servo motor. By means of the film tension adjusting device, stable tension in the film feeding process can be guaranteed, and transmission is stable.

Description

technical field [0001] The invention belongs to the field of labeling equipment and relates to a film tension adjusting device. Background technique [0002] Now most of the products on the market need to set logos to indicate the model specifications of the products, or to affix the manufacturer's logo, which is used to easily distinguish different manufacturers of similar products. Labeling machines are commonly used labeling equipment. At present, the types of labeling machines produced in my country are gradually increasing, and the technical level has also been greatly improved. It has shifted from the backward situation of manual and semi-automatic labeling to automatic high-speed labeling machines. The production volume of batteries is large, and all need labeling. For setting, it is necessary to indicate the capacity and brand of the battery on the battery label. However, due to the small size of the battery, it is necessary to ensure that the film tension on the label...

[0002] Now most of the products on the market need to set logos to indicate the model specifications of the products, or to affix the manufacturer's logo, which is used to easily distinguish different manufacturers of similar products. Labeling machines are commonly used labeling equipment. At present, the types of labeling machines produced in my country are gradually increasing, and the technical level has also been greatly improved. It has shifted from the backward situation of manual and semi-automatic labeling to automatic high-speed labeling machines. The production volume of batteries is large, and all need labeling. For setting, it is necessary to indicate the capacity and brand of the battery on the battery label. However, due to the small size of the battery, it is necessary to ensure that the film tension on the label is stable when labeling. At present, the labeling device is directly transported to the In the next link, no further lamination is carried out, resulting in some labels being not firmly pasted, affecting the appearance of the product and reducing the pass rate of the product
