[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figure 1 - Figure 3As shown, a film anti-fog performance testing device includes an operating table 1. A steam engine 4, a testing box 5, and a display 7 are mounted on the operating table 1. The testing box 5 is located between the steam engine 4 and the display 7. A winding assembly 2 is provided on the operating table 1. The winding assembly 2 includes a motor 21, which is installed at the bottom of the operating table 1. The output end of the motor 21 is connected to a first gear 22, which is located above the operating table 1. A turntable 24 is rotatably mounted on the operating table 1. A second gear 23 is connected to the outer wall of the turntable 24. A hollow column 25 is mounted on the turntable 24. A roller 28 is mounted on the top of the detection chamber 5. Two light sources 8 are installed inside the chamber. A jet nozzle is installed on the steam engine 4, located inside the detection chamber 5. A probe 6 is installed on the inner wall of the detection chamber 5, and the probe 6 is connected to the display 7 via a wire. The steam engine 4 blows steam into the detection chamber 5 through the jet nozzle. A membrane divides the internal space of the detection chamber 5 into two parts. One side of the membrane is in contact with the steam, forming a water mist. The light generated by the light source 8 penetrates the membrane. After the probe 6 detects the brightness, it transmits the data to the display 7. The display 7 converts the brightness data into anti-fogging properties. The data is displayed and recorded. Gear 23 meshes with gear 22. Roller 28 and hollow column 25 are located on both sides of the detection box 5. A through slot is provided on the detection box 5 between roller 28 and hollow column 25. The film can pass through the through slot on the detection box 5. Gear 22 drives turntable 24 to rotate through gear 23. When turntable 24 rotates, it drives the film winding drum to rotate through the cooperation of hollow column 25 and two support blocks 27. The film winding drum drives the film to move in the detection box 5 through winding, and gradually completes the detection operation of the whole roll of film. Two support blocks 27 are slidably installed on the inner wall of the hollow column 25. A screw 26 is threadedly connected to the inner wall of the hollow column 25. A conical head is provided at the bottom of the screw 26. Both support blocks 27 are in contact with the conical head of the screw 26. A handle is provided on the screw 26. When the screw 26 is turned by the handle, it moves downward. When the conical head on the screw 26 moves downward, it presses the two support blocks 27, causing the two support blocks 27 to move away from each other. During the outward movement of the two support blocks 27, they come into contact with the inner wall of the film winding drum, thus achieving the effect of supporting and fixing the inner wall of the film winding drum.

[0026] In this embodiment, the winding assembly 2 allows the hollow column 25 and the turntable 24 to work together with the roller 28 to unroll and rewind a roll of film. The anti-fog performance of the film is tested during the winding process, resulting in high work efficiency and avoiding the time wasted by manually unrolling and rewinding. The screw 26 and the two support blocks 27 work together to support and fix film winding cylinders with different inner diameters, enhancing applicability.

[0027] Example 2

[0028] Please see Figure 4 -Figure 6 As shown, the inside of the testing box 5 is equipped with a flow-disrupting assembly 3, which includes a reciprocating lead screw 33. The reciprocating lead screw 33 is rotatably mounted inside the testing box 5, with one end of the reciprocating lead screw 33 penetrating through the testing box 5. A worm gear 32 is connected to the end of the reciprocating lead screw 33 penetrating through the testing box 5. A worm gear 31 is connected to the top of the first gear 22. A ball bearing slider 34 is slidably mounted inside the testing box 5. A mounting bracket 35 is mounted on the ball bearing slider 34. Two short shafts 36 are rotatably mounted on the mounting bracket 35. Friction wheels 37 are connected to the bottom of the short shafts 36, and friction wheels 37 are connected to the top of the short shafts 36. Mounting plate 39, on which two baffles 310 are mounted. Inside the detection chamber 5, two friction strips 38 are installed, each contacting one friction wheel 37. The friction between the friction wheels 37 and the friction strips 38 creates significant friction, causing the friction wheels 37 to rotate as they move. The rotation of the two short shafts 36, via the two mounting plates 39, drives the four baffles 310 to rotate. The four baffles 310 rotate during their reciprocating motion, turbulenting the steam inside the detection chamber 5 and ensuring uniform steam distribution. The worm gear 31 and... The worm gear 32 meshes with the reciprocating screw 33, which has a reciprocating thread groove. The inner wall of the ball slider 34 is slidably connected to the reciprocating thread groove via balls. When the first gear 22 rotates, it drives the worm 31 to rotate, and the worm 31 drives the reciprocating screw 33 to rotate via the worm gear 32. An inclined block 311 is slidably installed on the inner wall of the detection box 5, and an elastic plate 312 is slidably installed on the inner wall of the detection box 5. A sponge 313 is installed on the elastic plate 312, and the sponge 313 keeps in contact with the film inside the detection box 5 to dry the moisture on the surface of the film. The ball slider 34 moves in contact with the inclined block 311 during its movement. When the surface block 311 contacts the surface block 312, a return spring is provided on the elastic plate 312. The elastic plate 312 is connected to the inclined block 311. When the ball slider 34 contacts the inclined block 311, the ball slider 34 pushes the inclined block 311 towards the elastic plate 312, so that the inclined block 311 drives the elastic plate 312 towards the sponge 313. When the elastic plate 312 moves towards the sponge 313, it can squeeze the sponge 313, so that the saturated water inside the sponge 313 is discharged, thus preventing the sponge 313 from becoming saturated after long-term use and affecting its water absorption effect.

[0029] In this embodiment, the turbulence-distributing component 3 is used to turbulent the steam in the detection chamber 5 by the reciprocating movement and rotation of the four turbulence plates 310, thereby making the steam distribution in the detection chamber 5 uniform and enhancing the uniformity of steam contact with the film surface, thus avoiding the impact of uneven steam contact with the film surface on the detection results. The sponge wipe 313 is used to wipe the surface moisture of the film before it leaves the detection chamber 5, thus avoiding the impact on the winding process. Furthermore, the elastic plate 312 will periodically squeeze the sponge wipe 313 to prevent the sponge wipe 313 from becoming saturated with moisture and affecting the water absorption effect.

[0030] In use, the operator places the film roll to be tested on roller 28, pulls out the film, passes it through the slot on the test chamber 5, and places the film take-up drum on turntable 24. By turning the handle, screw 26 moves downwards, and the conical head on screw 26 presses against two support blocks 27, causing them to move away from each other. During this outward movement, the two support blocks 27 contact the inner wall of the film take-up drum, achieving the effect of supporting and fixing the inner wall of the film take-up drum. The operator then fixes one end of the film passing through the slot onto the film take-up drum, and starts motor 21, steam generator 4, light source 8, probe 6, and display 7. Steam generator 4 blows steam into the test chamber 5 through a jet nozzle. The film divides the internal space of the test chamber 5 into two parts. One side of the film contacts the steam, forming water mist. The light generated by light source 8 penetrates the film, and probe 6 illuminates the light source. After the brightness is detected, the data is transmitted to the display 7. The display 7 converts the brightness data into anti-fog performance data, displays it, and records it. During this process, the motor 21 drives the first gear 22 to rotate, and the first gear 22 drives the turntable 24 to rotate through the second gear 23. When the turntable 24 rotates, it drives the film winding drum to rotate through the cooperation of the hollow column 25 and the two support blocks 27. The film winding drum moves the film in the detection box 5 through winding, gradually completing the detection of the entire roll of film. Through the setting of the winding assembly 2, the hollow column 25 and the turntable 24, in cooperation with the roller 28, roll the film to roll out before winding. The anti-fog performance is detected during the winding process, which is highly efficient and avoids the time wasted by manually unrolling and rewinding. Through the cooperation of the screw 26 and the two support blocks 27, it can meet the support and fixation of film winding drums with different inner diameters, enhancing its applicability.

[0031] When gear 22 rotates, it drives worm 31 to rotate. Worm 31 drives reciprocating screw 33 to rotate via worm wheel 32. When reciprocating screw 33 rotates, it drives ball slider 34 to move horizontally reciprocally through the cooperation of reciprocating thread groove and ball. When ball slider 34 moves, it drives two short shafts 36 to move synchronously via mounting bracket 35. When short shaft 36 moves, its bottom friction wheel 37 contacts friction strip 38. Due to the large friction between friction wheel 37 and friction strip 38, friction wheel 37 rotates when it moves. When friction wheel 37 rotates, it drives short shaft 36. The rotation allows the two short shafts 36 to rotate while moving. The rotation of the two short shafts 36 drives the four baffles 310 to rotate via the two mounting plates 39. The four baffles 310 rotate during their reciprocating movement, turbulently distributing the steam inside the detection chamber 5. During its reciprocating movement, the ball bearing slider 34 contacts the inclined block 311. When the ball bearing slider 34 contacts the inclined block 311, it pushes the inclined block 311 towards the elastic plate 312, causing the inclined block 311 to move... When the elastic plate 312 moves closer to the sponge 313, and the ball block slider 34 is not in contact with the inclined block 311, the inclined block 311 and the elastic plate 312 are reset by the elastic force of the return spring. The sponge 313 remains in contact with the film inside the detection box 5, thereby drying the water on the surface of the film and preventing water adhering to the surface of the film from affecting its quality after winding. When the elastic plate 312 moves towards the sponge 313, it can squeeze the sponge 313, causing the saturated water inside the sponge 313 to be discharged, preventing the sponge 313 from becoming saturated after long-term use and affecting its quality. Water absorption effect: By setting the turbulence component 3, the four turbulence plates 310 turbulently move and rotate to turbulent the steam in the detection box 5, so that the steam in the detection box 5 is evenly distributed, thereby enhancing the uniformity of steam contact with the film surface and avoiding the impact of uneven steam contact with the film surface on the detection results; by setting the sponge 313, the film can be dried before leaving the detection box 5, so as not to affect the winding process, and the elastic plate 312 will periodically squeeze the sponge 313 to prevent the sponge 313 from becoming saturated with water and affecting the water absorption effect.
