The membrane material on the rectangular frame belongs to a planar membrane, and the membrane of the planar membrane material is the most difficult membrane-stretching mode in all membrane-stretching modes, and secondary tensioning cannot be performed due to installation reasons. Therefore, the flat film is generally stretched manually, which can cause uneven tension applied to the film and cause wrinkling at the edges of the film. Meanwhile, after a plurality of rectangular units are installed together, the rectangular frame side rods are bent and deformed due to uneven stress of each rectangular frame membrane material.
Based on the reasons, the rectangular unit film stretching device designed by the invention can solve the problems, ensure the uniformity of the tension, eliminate the wrinkling phenomenon of the film material and improve the film stretching efficiency.

The working principle of the rectangular unit film stretching device is as follows: the rectangular frame is placed on a film stretching supporting frame in the film stretching device, and the side rod locating pin assembly is inserted into a hole in the rectangular frame, so that the purpose of locating the rectangular frame is achieved. And adjusting the adjusting nut on the side rod positioning pin assembly to level the side rod, and tightening the fastening nut to fix the side rod positioning pin assembly. The corner adjusting nuts on the four corner auxiliary supporting components are adjusted to enable the supporting seat to be in contact with the rectangular frame, the corners of the rectangular frame are guaranteed not to deform when the films are stretched, and the corner fastening nuts are screwed to fix the corner auxiliary supporting components. The method comprises the steps of spreading a membrane material on a rectangular frame, clamping the middle of the membrane material by using a long membrane pulling plate, clamping corners of the membrane material by using an arc membrane pulling plate, connecting a hydraulic cylinder with the long membrane pulling plate by using a U-shaped hanging ring, and connecting a flower basket bolt with the arc membrane pulling plate by using the U-shaped hanging ring. The hydraulic cylinder works, the tension of the hydraulic cylinder can be adjusted by adjusting the pressure of the hydraulic cylinder, and after the hydraulic cylinder tightens the membrane material, the tension of the corner of the membrane material is adjusted by the basket bolt so as to eliminate corner wrinkles.
