[0002] The PE protective film is the simplest high-molecular organic compound and the most widely used high-molecular material in the world today. When the PE protective film is processed and produced, its tensile strength needs to be detected. Usually, a tensile testing device is used for the detection. The existing tensile testing device is the equipment used for the tensile testing during the processing and production of the PE protective film. The tensile testing device is convenient for uniformly clamping and fixing the end part of the PE protective film during the detection, effectively and accurately detecting, and improving the uniformity of the clamping and fixing force and the accuracy of the detection when the tensile testing device processes the PE protective film.

[0033] Working principle and usage process of the present utility model: For this kind of PE protective film detection device, before use, first place the tensile testing device main body 100 stably at the position of use by contacting the placement surface with the lower surface of the detection host 101. After the tensile testing device main body 100 is stably placed, fixedly install the PE protective film at the end of the fixing plate 103. After installation, the cylinder 108 moves to drive the pull plate 106 to move upward. When the pull plate 106 moves, the sliding hole 104 slides relative to the sliding rod 105 to stably move the pull plate 106, and when the pull plate 106 is stably moved, it drives the PE protective film to be stably pulled for tensile testing;

[0034] Then, when the tensile testing device main body 100 is fixedly installed before use, close the end of the PE protective film on the surface of the fixing plate 103 to contact the fixed clamping plate 1031. Hold the handwheel 1038 and drive the rotating rod 1035 and the driving gear 1036 to rotate. When the driving gear 1036 rotates, it engages with the outer surface of the driven gear 1037 to drive the lead screw 1039 to rotate, facilitating the simultaneous rotation of the four lead screws 1039 to move the moving head 1030 on the outer surface of the lead screw 1039. When the moving head 1030 moves on the outer surface of the lead screw 1039, it drives the moving clamping plate 1034 to move outward to clamp and fix on the surface of the PE protective film, enabling the moving clamping plate 1034 to be evenly stressed during moving adjustment and clamping and fixing, clamping and fixing the middle and both ends evenly. Rotate the threaded rod 109 again to drive the arc tooth plate 1091 to move and clamp on the surface of the rotating rod 1035, facilitating the reinforcement of the clamping and fixing after the moving clamping plate 1034 is clamped and fixed, and preventing side loosening and falling off during tensile testing, effectively and accurately detecting, and improving the uniformity of the clamping force and the accuracy of the detection of the tensile testing device main body 100 when processing the PE protective film;

[0035] Finally, when the tensile testing device main body 100 is in use for detection, inject lubricating oil into the interior of the oil storage tank 1052 through the oil injection port 1051. After the interior of the oil storage tank 1052 is filled with oil, immerse the drainage brush 1053 in the oil, and let the drainage brush 1053 drain to the end and contact the outer surface of the sliding rod 105. When the pull plate 106 moves to drive the sliding between the sliding rod 105 and the sliding hole 104 during detection, lubricate the outer surface of the sliding rod 105 by the contact sliding of the drainage brush 1053. During frequent movement and detection, it is not easy to cause friction damage, smoothly control the movement of the pull plate 106 to pull the PE protective film for detection, and improve the lubrication effect on the outer surface of the sliding rod 105 when the tensile testing device main body 100 reinforces the PE protective film.
