Abstract
The invention relates to a chain assembly device of a transverse stretching device. The chain assembly device is characterized by comprising a machine base, a workbench plate, a lower anvil plate, a positioning mechanism, a driving oil cylinder, an anvil head, a pressing block and a hydraulic box, wherein the workbench plate is fixedly arranged on the machine base through support by the machine base, the lower anvil plate is arranged on the workbench plate, the positioning mechanism is fixed on the lower anvil plate, the machine base is provided with the driving oil cylinder positioned above the workbench plate through an oil cylinder support, a piston rod of the driving oil cylinder is connected with the anvil head, and the hydraulic box is in communication with the driving oil cylinder through a pipeline. The assembly device has the advantages that the assembly work of a chain can be completed by 2 to 3 operators in a short period of time, the time and the labor are saved, the starting time of the stretching device can be advanced by 1 to 2 days, and the stopping time is shortened; and in addition, the assembly quality of the chain and the yield of the stretched film product areimproved. The chain assembly device has simple structure and can reduce the device failure rate and the processing cost.
Description
technical field [0001] The invention belongs to the technical field of film transverse stretching equipment, in particular to a chain assembly device of transverse stretching equipment. Background technique [0002] At present, the chain is an important part of the horizontal stretching equipment of the BOPP production line. In film production, the PP material is cast into a thick sheet by touch, and stretched by the longitudinal stretching equipment into a thin sheet with a width of about 600mm and a thickness of about 3mm. The thin sheet enters the horizontal stretching process. The equipment uses two sets of chain clips to clamp both sides of the sheet. The chain clips are installed on the two chains and walk along two predetermined tracks respectively. The distance between the two tracks changes from narrow to wide, and finally the sheet is stretched transversely to a width of about 4000mm and a thickness of about 0.02mm. film. With the increase of production thickness ...
