[0002] With the improvement of living standards, protective films have also evolved into different film materials suitable for different application scenarios. Different application scenarios have different performance requirements for protective films. For example, some application scenarios require the protective film to have high heat resistance, some application scenarios require the protective film to have good chemical stability, and some application scenarios require the protective film to have high tensile resistance. Different performance requirements correspond to different testing methods. Among them, manufacturers usually use a protective film tensile testing machine to test the tensile resistance of the protective film.

[0003] When testing the protective film, it is necessary to first fix both ends of the protective film and then perform a tensile test on the protective film. When placing and clamping the protective film, the upper and lower ends of the protective film are not convenient for clamping and fixing in the existing tensile testing machine, and the protective film is very easy to fall off during the tensile test, affecting the test results of the protective film.

The present utility model is further described in detail below in conjunction with the accompanying drawings.

[0020] like Figure 1-5 As shown, the utility model provides a protective film tensile testing machine, including a base 1, a pulling assembly 2 and an anti-skid clamp assembly 3, support columns 4 are arranged on both sides of the top of the base 1, and slots 5 are opened on the opposite side walls of the two groups of support columns 4, and sliders 6 are slidably arranged in the slots 5. A pulling plate 7 is connected between the two groups of sliders 6. Two groups of anti-skid clamp assemblies 3 are arranged and are respectively installed at the bottom of the pulling plate 7 and the top of the base 1. The two groups of anti-skid clamp assemblies 3 are arranged opposite to each other up and down; the anti-skid clamp assembly 3 includes a clamping back plate 8, a clamping front plate 9, a clamping corrugated plate 10 and a clamping The corrugated plate 11 and the two groups of clamping back plates 8 are respectively installed at the bottom of the pull plate 7 and the top of the base 1. The two side ends of the front side of the clamping back plate 8 are respectively fixed with pillars 12. The clamping front plate 9 is fixedly set at the end of the pillar 12. The clamping corrugated plate 10 is fixed on the front side wall of the clamping back plate 8. The two side ends of the clamping corrugated plate 11 are slidably set on the pillar 12. The clamping corrugated plate 10 and the clamping corrugated plate 11 have raised and recessed grooves that fit each other. Anti-slip strips are set at the upper and lower end protrusions of the clamping corrugated plate 10 to increase the clamping friction and improve the clamping stability.

[0021] like Figure 1-4 As shown, a screw 13 is rotatably arranged on the front side wall of the clamping corrugated plate 11, and the screw 13 threadably penetrates the clamping front plate 9. A knob 14 is arranged at the front end of the screw 13, and the screw 13 is rotated by the knob 14. Under the thread transmission action of the screw 13, the clamping corrugated plate 11 is driven to move toward the clamping corrugated plate 1 10 on the support 12, thereby clamping the upper and lower ends of the protective film between the clamping corrugated plate 10 and the clamping corrugated plate 11. Due to the design of the protrusions and grooves of the corrugations on the opposite sides of the clamping corrugated plate 10 and the clamping corrugated plate 11, the protective film has multiple twists and turns at the pressing point, and the stability is higher.

[0022] like Figure 1-4 As shown, the pulling assembly 2 includes a threaded rod 15 and a rotating rod 16. Two groups of threaded rods 15 are provided, and the two groups of threaded rods 15 are respectively provided in two groups of slots 5. The top and bottom ends of the threaded rods 15 are respectively rotatably provided on the top wall and bottom wall of the slot 5. The threaded rods 15 and the slider 6 are threadedly adapted and penetrated. Two groups of rotating rods 16 are provided, and the bottom end of the rotating rods 16 is rotatably provided on the top wall inside the base 1.

A transmission wheel 2 19 is sleeved on the rotating rod 16. A transmission belt 20 is connected between the transmission wheel 18 and the transmission wheel 2 19. The driving motor 17 drives the rotating rod 16 to rotate through the transmission belt 20, and the rotating rod 16 drives the threaded rod 15 to rotate. Under the thread transmission action of the threaded rod 15, the slider 6 is driven to slide in the slot 5, and the slider 6 drives the pulling plate 7 to move, so as to perform a pulling test on the protective film.

[0024] When in use, the upper and lower ends of the protective film are respectively placed between the clamping corrugated plate 10 and the clamping corrugated plate 2 11 of the two sets of anti-slip clamp assemblies 3, and the screw rod 13 is rotated by the knob 14. Under the threaded transmission action of the screw rod 13, the clamping corrugated plate 2 11 is driven to move toward the clamping corrugated plate 10 on the support 12, so that the upper and lower ends of the protective film are clamped between the clamping corrugated plate 10 and the clamping corrugated plate 2 11. Due to the design of the protrusions and grooves of the corrugations on the opposite sides of the clamping corrugated plate 10 and the clamping corrugated plate 2 11, the pressing part of the protective film has multiple twists and turns to achieve stable clamping, and then the driving motor 17 is started. The driving motor 17 drives the rotating rod 16 to rotate through the transmission belt 20, and the rotating rod 16 drives the threaded rod 15 to rotate. Under the threaded transmission action of the threaded rod 15, the slider 6 is driven to slide in the slot 5, and the slider 6 drives the pulling plate 7 to move, so as to perform a pulling test on the protective film.
