Mechanism for stretching roller shear framework

The invention discloses a mechanism for stretching a roller shear framework. The mechanism for stretching the roller shear framework comprises a first stretching roller set, a second stretching rollerset and a working table. The first stretching roller set and the second stretching roller set are arranged on the working table. A vertical plate is arranged on the working table. The vertical plateis located between the first stretching roller set and the second stretching roller set. Fixing shafts in pairs are fixed to a side face of the vertical plate. Sliding bearings are arranged outside the fixing shafts in a sleeving manner. An automobile sealing strip roller shear framework produced by adopting the mechanism for stretching the roller shear framework is uniform in size and smooth andsteady in stretching; a belt material is not easy to break in the stretching process; and the rate of finished products can be improved greatly. 本发明公开了一种滚剪骨架拉伸机构，包括第一拉伸辊组、第二拉伸辊组、工作台，所述第一拉伸辊组和第二拉伸辊组设置在工作台上，工作台上设置有立板，所述立板位于第一拉伸辊组
