The invention discloses a transverse film stretching machine, and relates to the technical field of film production equipment. The transverse film stretching machine comprises a traction mechanism, afilm clamping mechanism, a film releasing mechanism and a temperature control mechanism, all of which are mutually matched. The temperature control mechanism comprises a plurality of constant-temperature chambers erected on the traction mechanism side by side. Each constant-temperature chamber comprises a plurality of heating chambers which are arranged in a pre-heating area, a stretching area andthe front middle section of a forming area, and a plurality of cooling chambers arranged at the rear section of the forming area, wherein the temperatures of the heating chambers are gradually increased, and the temperatures of the cooling chambers are gradually reduced. The transverse film stretching machine can achieve continuous guiding and transverse stretching work for films, and is high inautomation degree, uniform in stretching and high in work efficiency, and the yield of the produced films is high.
Description
technical field [0001] The invention relates to the technical field of film production equipment, in particular to a film transverse stretching machine. Background technique [0002] In the production process of the film, the film needs to be stretched horizontally after the longitudinal stretching process. The traditional equipment stretches unevenly, and the produced film often has defects such as edge shrinkage, and the yield of good products is low. Contents of the invention [0003] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a film transverse stretching machine, which has uniform stretching, high work efficiency, and high yield of film produced. [0004] The technical scheme that the present invention takes is: [0005] A film transverse stretching machine, comprising: [0006] frame; [0007] a traction mechanism, the traction mechanism is erected on the frame, and includes a symmetrically arranged first tr...
