Description

Technical Field

[0001] This utility model relates to the field of polyester film technology, specifically to a polyester film tensile strength testing device. Background Technology

[0002] PET film is a film with comprehensive performance characteristics. It has good optical properties, good transparency, low haze, and high gloss. It also has excellent mechanical properties, with the best toughness among all thermoplastics. Its tensile strength and impact strength are much higher than those of ordinary films. In addition, it has good stiffness and dimensional stability, making it suitable for secondary processing such as printing, paper bags, and coating.

[0003] Existing patent document CN222419806U discloses a material tensile testing device. The movable tensile mechanism includes a ball screw mounted above a base platform, a drive motor mounted at one end of the ball screw, a movable stage mounted on the outer surface of the ball screw, a longitudinal plate mounted above the movable stage, a second fixed frame mounted on one side above the longitudinal plate, a second electromagnetic clamping assembly mounted opposite each other on the inner side of the second fixed frame, second telescopic hydraulic cylinders mounted on the front and rear sides of the second electromagnetic clamping assembly, a tensile wire assembly mounted on the other side above the longitudinal plate, and a tensile sensor positioned between the longitudinal plate and the tensile wire assembly. The fixing mechanism includes a mounting platform above the base platform, a vertical plate mounted opposite each other above the mounting platform, support columns mounted opposite each other on the vertical plate, a first fixed frame mounted at the other end of the support columns, and a second C-shaped frame mounted opposite each other inside the second fixed frame. A second electromagnetic clamping frame is mounted opposite each other on the second C-shaped frame, and strong fixing electromagnetic columns are equidistantly mounted on the inner wall of the second electromagnetic clamping frame. The first electromagnetic clamping assembly includes a first C-shaped frame disposed opposite to the inner side of the first fixed frame, on which a first electromagnetic clamping frame is mounted. The telescopic detection assembly includes a detector disposed above the first electromagnetic clamping assembly, with a detection probe installed at the detection end of the detector and an electric telescopic rod installed on one side of the detector. Through the set moving tension mechanism, the clamping of the material is effectively detected. According to the length of the material being detected, the drive motor is started, driving the ball screw to rotate, which drives the moving table and the longitudinal plate to move laterally, and at the same time drives the second electromagnetic clamping assembly disposed inside the second fixed frame to move. When it moves to the end of the material being detected, it stops and the second electromagnetic clamping assembly is activated to electromagnetically clamp the material being detected. At the same time, the tension wire assembly and tension sensor are set to apply tension to the material, ensuring the clamping effect of the material and preventing the material from falling off due to excessive tension. The position of the second electromagnetic clamping assembly can be adjusted according to the length of the material. The operation is simple and highly practical.

[0004] However, in the existing technology CN222419806U patent, the suspension and tensile testing capabilities of a material tensile testing device are poor. As a result, in the actual use of the material tensile testing device, it is impossible to suspend and adjust the polyester film as needed, which makes it inconvenient to perform tensile testing on the polyester film and affects the tensile testing effect of the material tensile testing device.
