Embodiment Construction

[0010] See figure 1 , figure 2 , image 3 , the present invention includes a bracket 4, the main shaft 2 of the bracket 4 is installed on the plate part 1, and the tightening roller 11 is installed on the bracket 4, which includes a non-resistance cylinder 7. The non-resistance cylinder 7 is installed on the plate part 1 through the nut 6; the guide rod of the non-resistance cylinder 7 is connected with the connecting block 8; the connecting block 8 is set on the rotating rod 10, and the rotating rod 10 is installed on the bracket 4; tighten the roller 11 is parallel to the main axis of support 2; in the figure, 3 and 5 are bearings, 9 and 12 are blocking rods, and 13 is a film material. When the mechanism is working, the film material 13 is wound on the tensioning roller 11. When the non-resistance cylinder 7 is ventilated, the cylinder connecting block 8 is pulled, and the cylinder connecting block 8 drives the bracket 4 to rotate, and the bracket 4 drives the tightening ...

Abstract

The invention relates to a membrane type material tensioning structure which can adjust tensile force effectively, is stable and comprises a supporting bracket. The main shaft of the supporting bracket is arranged on a plate type part, and the supporting bracket is provided with a tensioning roller. The membrane type material tensioning structure is characterized by comprising a damper-free cylinder which is arranged on a plate type part.

Description

(1) Technical field [0001] The invention relates to a membrane material tensioning mechanism. (2) Background technology [0002] The previous membrane material tensioning mechanism includes a motor and a bracket, a tightening roller is installed on the bracket, the main shaft of the bracket is installed on the plate part, the film material bypasses the tightening roller, and the motor is installed on the plate part. The motor is connected with the support through the connecting rod, and the connecting rod connected with the motor is driven to rotate through the rotation of the motor, thereby driving the support to rotate, the tightening roller on the support rotates around the main shaft, and the film material enters the tightened state. Its disadvantages are: it is driven by a motor, and its tension force is not easy to adjust and control, and the motor and the support are driven by connecting rods, so the transmission process is unstable and the structure is easy to loosen...
