Abstract

The invention discloses a film tension device, which comprises a rack; two sides of the rack are respectively provided with a fixing plate; a transmission shaft is arranged between the two fixing plates; a first sliding shaft and a second sliding shaft which are parallel with each other are arranged on the two fixing plates; the first sliding shaft and the second sliding shaft can synchronously slide along the coaxial direction; two cams are connected with the transmission shaft; the two cams respectively correspond to the two fixing plates; both the two cams are provided with a radical ejecting part and a coaxial ejecting part; when the radical ejecting parts are matched with the first sliding shaft or the second sliding shaft, the first sliding shaft and the second sliding shaft leave far away from each other; when the coaxial ejecting parts are matched with the first sliding shaft or the second sliding shaft, the first sliding shaft and the second sliding shaft move coaxially and simultaneously. The film tension device has a good tension effect when a film is tensed; and the structure of the film tension device is simpler.

Description

technical field [0001] The invention relates to a film tensioning device. Background technique [0002] In the process of product decoration, it is often necessary to tension the film, such as in the process of in-mold transfer printing, hot stamping or lamination of large-sized products, but the existing film tensioning device is difficult to ensure The quality of the tension film, and the complex structure of some film tension devices still need further improvement. Contents of the invention [0003] The object of the present invention is to overcome the defects of the prior art and provide a film tensioning device. The present invention has good tensioning effect when tensioning the film, and the structure of the device is simpler. [0004] Its technical scheme is as follows. [0005] A film tensioning device includes a frame, fixed plates are respectively arranged on both sides of the frame, a transmission shaft is arranged between the two fixed plates, and a first s...
