During operation, when the film is detected, a bad film will be broken, and debris will fall from between the fixed frames 2. At this time, the collecting box 4 is located at the bottom of the film in the detection area, and some of the generated debris can be collected. Through the above structure, the collecting box 4 can be set to collect the broken film debris, so as to reduce the film debris scattered on the surface of the bottom plate 1, which makes it inconvenient to clean and collect.

Through the above structure, the oil storage tank 6 and the sponge block 62 are set, and the lubricating oil can be smeared on the surface of the rack 14 during the movement of the rack 14. At the same time, the meshing of the rack 14 and the gear 12 can make the lubricating oil adhere to the surface of the gear 12, thereby reducing the friction between the gear 12 and the rack 14, so as to reduce the situation where the friction is large and the wear and tear causes deformation and damage.

[0044] Reference Figure 7 A frame 7 is fixedly connected to the top of the bottom plate 1, and a collecting box 71 is placed in the frame 7. The collecting box 71 is located below the sponge block 62. During operation, when the rack 14 passes through the sponge block 62, the toothed structure of the sponge block 62 will scrape the sponge block 62, causing the lubricating oil to drip onto the surface of the bottom plate 1.

During operation, when the film is fixed, the rubber pad 23 will move toward the surface of the film. At this time, the rubber pad 23 will drive the pressure strip 8 to move toward the card slot 81. At this time, the film is located between the pressure strip 8 and the card slot 81, and the pressure strip 8 will press the film into the card slot 81. Through the above structure, the pressure strip 8 and the card slot 81 are set, and when the pressure plate 22 presses the film, the pressure strip 8 can press the film into the card slot 81. At this time, the pressed film can be bent, the contact surface between the film and the rubber pad 23 can be increased, and the fixing effect of the film can be improved to reduce the slippage of the film in the detection chamber.

[0046] Reference Figure 2 A pair of baffles 9 are fixedly connected to the side wall of the support frame 15. The baffles 9 are made of transparent material. When a bad film is broken during operation, debris and powder will spread to the surrounding. At this time, the baffles 9 will block the debris and powder spreading to the surrounding. Through the above structure, the baffles 9 can block the flying debris and powder when the film is broken, so as to reduce the debris and powder from splashing to the outside of the support frame 15, causing pollution and harm to the operator, and play a protective role to improve the safety during use.

[0047] The implementation principle of the explosion-proof detection device for high-temperature resistant metallized polypropylene film according to the embodiment of the present invention is as follows: when performing explosion-proof detection on the film, after the film is fixed by a fixing component located outside the support frame 15 and inside the loading rack 13, the motor 11 is started to drive the gear 12 to rotate. At this time, the gear 12 can drive the rack 14 and the loading rack 13 to move, and the loading rack 13 located outside is moved to the inside of the support frame 15. When the fixed film is moved under the pressure head 17, the rotation of the motor 11 is stopped. At this time, the other end of the loading rack 13 will be driven to move to the outside of the support frame 15, and then the hydraulic cylinder 16 is started to stretch and drive the pressure head 17 to move toward the film. The pressure head 17 applies pressure to the film to perform explosion-proof detection, and the test pressure data will be displayed on the side of the support frame 15. On the display, when the film in the support frame 15 is detected, other films to be detected can be fixed in the loading rack 13 outside the support frame 15 at the other end. When the film detection in the support frame 15 is completed, the motor 11 is started again to reverse and move the film to be tested into the support frame 15, and at the same time, the film after the detection is moved to the outside of the support frame 15, and then the detected film is taken off, and then the hydraulic cylinder 16 is started to drive the pressure head 17 to detect the new film, and the loading rack 13 is driven to move back and forth by circulation, so that two films can be fixed for uninterrupted detection. When fixing the film, the edge of the film is placed on the bottom of the fixed frame 2, and then the screw 21 is rotated forward to drive the pressure plate 22 and the rubber pad 23 to move toward the bottom of the fixed frame 2. When the rubber pad 23 contacts the film, it can be The film is pressed to fix its position, and then the film is tested. After the test is completed, the screw 21 is rotated in the opposite direction to drive the pressure plate 22 and the rubber pad 23 away from the film, and then the film is removed from the fixed frame 2. When the film is fixed in position between the fixed frames 2, the cylinder 3 is started to contract and drive the slide plate 31 to move toward the inner wall of the upper material rack 13. At this time, the fixed frame 2 can be driven to move toward the inner wall of the upper material rack 13. At this time, the film fixed between the fixed frames 2 can be tightened, and then the contraction of the cylinder 3 is stopped. When the film is tested, a bad film will be broken, and debris will fall from between the fixed frames 2. At this time, the collection box 4 is located at the bottom of the film in the test area, and some of the generated debris can be collected. Before testing, the pull-out box 51 is inserted into the collection box 4 through the slot 5. When testing When the film is broken during the test, some of the debris will fall into the pull-out box 51 and be collected. After the test is completed, the pull-out box 51 can be pulled out, and the collected debris can be poured out and then put back into the collection box 4. Before the test, the lubricating oil is added to the oil storage tank 6. At this time, the lubricating oil flows into the sponge block 62 through the oil outlet pipe 61, so that the sponge block 62 is filled with the lubricating oil as a whole. When the rack 14 moves, the sponge block 62 will smear the lubricating oil on the surface of the rack 14, so that the rack 14 contacts the gear 12 with the lubricating oil. Before the test, the lubricating oil is added to the oil storage tank 6. At this time, the lubricating oil flows into the sponge block 62 through the oil outlet pipe 61, so that the sponge block 62 is filled with the lubricating oil as a whole. When the rack 14 moves, the sponge block 62 will smear the lubricating oil on the surface of the rack 14.Thus, the rack 14 makes the lubricating oil contact with the gear 12. When the film is fixed, the rubber pad 23 will move toward the surface of the film. At this time, the rubber pad 23 will drive the pressure strip 8 to move toward the slot 81. At this time, the film is located between the pressure strip 8 and the slot 81. The pressure strip 8 will press the film into the slot 81. When the bad film is broken, debris and powder will spread around. At this time, the baffle 9 will block the debris and powder spreading around.
