Problems solved by technology

The existing chain tensioning system generally uses the oil cylinder as the output power source to tension the chain, and the oil cylinder needs to be connected to the oil circuit of the hydraulic station, which has the risk of oil leakage and affects the quality of the product
However, using the cylinder as the output power source has noise problems, the required cylinder diameter needs to be increased, and a large installation space is required

Abstract

The invention discloses a chain tensioning system for transversely pulling a film. The chain tensioning system comprises a hydraulic cylinder, a gas-liquid converter, a gas pressure maintaining mechanism, a first fixed rack, a second fixed rack, a sliding base arranged at the top of the first fixed rack in a sliding mode, a first driving shaft, a first chain wheel, a second driving shaft, a secondchain wheel and a chain wound on the first chain wheel and the second chain wheel. The hydraulic cylinder is used for driving the sliding base to move in the direction away from the second fixed rackto achieve tensioning of the chain. According to the chain tensioning system for transversely pulling the film, the influence on the field environment can be reduced under the condition that enough output force is guaranteed.

Description

technical field [0001] The invention relates to the technical field of a film stretching production line, in particular to a chain tensioning system for film horizontal stretching. Background technique [0002] Chain clips are widely used in the film stretching production line, and the chain clips are installed on the circular guide rails, which are guided by the guide rails during movement. There is a set of symmetrical circular guide rails on both sides of the film, and the chain clips on the guide rails on both sides are synchronized under the traction of the chain. running, and the two ends of the annular guide wheel are respectively provided with sprockets, the chain is wound on the two sprockets, and the sprockets are driven to rotate by the drive shaft. The two sides of the thick film to be stretched are fed into the chain clamps, the chain clamps are closed, and the width change between the guide rails on both sides makes the chain clamps on both sides of the film pu...
