Abstract

The invention discloses a tensioning mechanism of a film-pasted coiled tube core. The tensioning mechanism comprises a spindle, wherein two locking blocks are arranged at two ends of the spindle respectively and are fixed to the spindle through a plurality of bolts, the middle of the spindle is a central shaft, the central shaft penetrates through the locking blocks for installation, the central shaft penetrates an installing block to be fixed in a base, and the base is installed on a rack of a film-pasted machining machine tool. The spindle is provided with three large gaps, the gaps are circular-arc-shaped and are arranged peripherally, two fixing blocks are arranged in each large gap, and a tensioning strip is arranged between the two fixing blocks. The tensioning mechanism of an existing film-pasted coiled tube core is improved in design, the plastic tensioning strip is designed and installed in the large gaps, so that the tube core firmly attaches to the tensioning strip during rotation, and a tensioning effect is played on the tube core.

Description

Technical field: [0001] The invention relates to the technical field of film pasting and winding machinery, in particular to a tensioning mechanism for film pasting and winding tube cores. Background technique: [0002] In order to facilitate the storage and handling of the film, the film is generally wrapped around the city. In this case, a winding machine is used to roll the loose film onto the die through the winding machine. Therefore, the die needs to be fixed on the fixing device first. In the above, the application number is 201310163736.6, which includes a suction device and a winding shaft. The winding shaft is provided with a central hole with one end open and one end closed. The shaft is also formed with a number of air holes that are perpendicular to the axial direction and communicate with the central hole. The openings of the air holes are arranged on the circumferential surface of the winding shaft. There are several elongated waist-shaped holes depressed dow...
