Description

Technical Field

[0001] The invention belongs to the technical field of anti-reflection films, and in particular relates to an anti-reflection film for a subway shielding door and a preparation device thereof. Background Art

[0002] In modern buildings and rail subways, thermal insulation is a very important performance indicator. With the rise in energy costs and the improvement of people's requirements for indoor environmental comfort, the demand for materials that effectively block heat transfer is growing. When the subway is running, the environment in the tunnel is complex, especially in summer, the temperature in the tunnel can be much higher than that on the platform due to factors such as frequent friction between trains and heat dissipation of equipment; in winter, it is just the opposite, and the tunnel is colder. The shield door with thermal insulation function can block the heat exchange between the tunnel and the platform, allowing the platform to maintain a relatively comfortable and stable temperature, reducing the discomfort caused by the temperature difference of passengers, and not having to experience hot and cold while waiting for the train. Traditional thermal insulation materials such as glass film have certain limitations. For example, ordinary glass film mainly insulates by reflecting or absorbing part of the solar radiation, but the thermal insulation effect is limited. Anti-reflection film uses the light absorption characteristics of dyes to achieve anti-reflection function. Compared with traditional anti-reflection film, anti-reflection film has the advantages of lower cost, however, simple anti-reflection film also has shortcomings in thermal insulation. Ordinary anti-reflection film mainly adjusts visible light, and has poor thermal insulation effect on the main bands of heat transfer such as infrared light. Summary of the invention

[0003] In view of this, the purpose of the present invention is to provide an anti-reflection film for subway shielding doors and a preparation device thereof. The anti-reflection film not only has the conventional anti-reflection function, but also has a unidirectional high reflectivity, which can reduce heat transmission when facing outward.

[0004] In order to achieve the above object, the present invention provides the following technical solutions:

[0005] The invention discloses an anti-reflection film for a subway shielding door, comprising a substrate layer, a conductive layer, an anti-reflection layer and a dyed protective layer which are sequentially arranged from the inside to the outside, wherein a plurality of arc-shaped convex structures are arranged in parallel on the side of the substrate layer facing the conductive layer, and a plurality of columnar prism structures are arranged in parallel on the side of the substrate layer away from the conductive layer, wherein the columnar prism structures correspond to the arc-shaped convex structures one by one, and the columnar prism structures at least comprise a vertical surface perpendicular to the substrate layer and an inclined surface adjacent to the vertical surface and inclined relative to the substrate layer.

[0006] A preparation device for an anti-reflection film for a subway screen door, used for manufacturing the anti-reflection film as described above, the preparation device comprises a clamping assembly for clamping the anti-reflection film, a displacement driving assembly for driving the clamping assembly to move longitudinally, a hydraulic telescopic assembly arranged on the upper side of the clamping assembly, and a cutter assembly installed on the hydraulic telescopic assembly, wherein the hydraulic telescopic assembly can drive the cutter assembly to move vertically so as to process the columnar prism structure on the substrate layer.

[0007] Further, the cutter assembly includes a knife plate, a plurality of knife grooves provided on the knife plate, and cutters installed in the knife grooves in a one-to-one correspondence with the knife grooves, and a plurality of cutters are staggered vertically. The cutter includes a knife block, a knife seat, a knife seat longitudinal displacement member, a slide seat, and a slide seat transverse displacement member. The vertical surface and the inclined surface are formed on the knife block at the same time. The knife block is installed on the knife seat, and the knife seat is installed on the slide seat along the longitudinal sliding direction. A knife seat longitudinal displacement member for controlling the longitudinal displacement of the knife seat is installed on the slide seat, and the slide seat is installed in the knife groove along the transverse sliding direction. A slide seat transverse displacement member for controlling the transverse displacement of the slide seat is installed on the knife plate.

[0008] Furthermore, a spherical surface is provided on the side of the blade block, and a ball groove matching the spherical surface is opened on the inner side of the blade seat. The blade block can deflect around a vertical line, and the spherical surface is rotatably installed in the ball groove. The blade block and the blade seat are locked by a locking piece.

[0009] Furthermore, the locking member includes a screw, which is threadedly connected to a threaded hole provided on the tool holder, and the inner end of the screw is inserted into the threaded hole and abuts against the surface of the spherical surface.

[0014] The beneficial effects of the present invention are:

[0015] The invention discloses an anti-reflection film for a subway shielding door and a preparation device thereof. By setting an arc-shaped convex structure on a substrate layer, the anti-reflection film can be used for focusing light. The focused light is then reflected by a columnar prism structure. When the light is irradiated to the surface, it will be reflected multiple times on each inclined surface of the pyramid. The number of reflections of the light on the surface of the substrate layer is greatly increased, thereby improving the reflectivity.

DETAILED DESCRIPTION

[0027] like Figure 1 As shown, the anti-reflection film for subway shielding doors disclosed in the present invention comprises a substrate layer 1, a conductive layer 2, an anti-reflection layer 3 and a dyed protective layer 4 arranged in sequence from the inside to the outside. The outside here refers to the side facing the outside of the vehicle, that is, the side facing the sunlight, and the opposite side is the inside. Among them, a plurality of arc-shaped convex structures 5 are arranged in parallel on the side of the substrate layer 1 facing the conductive layer 2, and the cross section of the arc-shaped convex structure 5 is in a bad arc shape. A plurality of columnar prism structures 6 are arranged in parallel on the side of the substrate layer 1 away from the conductive layer 2, and the columnar prism structures 6 correspond to the arc-shaped convex structures 5 one by one. The columnar prism structures 6 at least include a vertical surface 7 perpendicular to the substrate layer 1 and an inclined surface 8 adjacent to the vertical surface 7 and inclined relative to the substrate layer 1. The vertical surface 7 refers to the plane perpendicular to the film in the normal state, and the inclined surface 8 is parallel to the film and inclined at a certain acute angle.

[0028] In the anti-reflection film disclosed in the present invention, the parabolic-shaped substrate layer 1 can converge light parallel to the axis of symmetry to a focus, or reflect light emitted from the focus into parallel light. When light is irradiated to the concave side of the parabola, the light will be reflected and concentrated according to the optical properties of the parabola. This shape utilizes the law of reflection in optics, so that the light can be reflected according to a specific rule, thereby improving the reflectivity. The concentrated light is then reflected by the columnar prism structure 6. When the light is irradiated to the surface, it will be reflected multiple times on each inclined surface of the pyramid. The number of reflections of light on the surface of the substrate layer 1 is greatly increased, thereby improving the reflectivity. The anti-reflection film of the present invention not only has the conventional anti-reflection function, but also has a unidirectional high reflectivity. When facing outward, the high reflectivity can reduce heat transmission and has a good heat insulation effect.

[0029] like Figures 2 to 7As shown, a preparation device for anti-reflection film for subway screen doors is used to manufacture the anti-reflection film as described above. In order to improve the processing efficiency and accuracy of multiple columnar prism structures 6 on the anti-reflection film, this preparation device is invented. Among them, the preparation device includes a clamping assembly for clamping the anti-reflection film, a displacement driving assembly for driving the clamping assembly to move in the longitudinal direction, a hydraulic telescopic assembly 9 arranged on the upper side of the clamping assembly, and a cutter assembly 10 installed on the hydraulic telescopic assembly 9. The displacement driving assembly adopts a conveyor belt, which can adapt to the processing of multiple groups of substrate layers 1. The clamping assembly is used to clamp them for easy operation. The hydraulic telescopic assembly 9 can drive the cutter assembly 10 to move vertically to process the columnar prism structure 6 on the substrate layer 1. In the device of the present invention, the conveyor belt is driven horizontally, and the moving direction of the conveyor belt is the longitudinal direction.

[0030] In this embodiment, the cutter assembly 10 includes a cutter plate 11, a plurality of cutter grooves 12 formed on the cutter plate 11, and cutters 13 installed in the cutter grooves 12 in a one-to-one correspondence with the cutter grooves 12. The cutter plate 11 is rectangular as a whole, the normal of the cutter plate 11 is along the longitudinal direction, and the cutter grooves 12 extend in the transverse direction. The cutters 13 are staggered vertically, and the cutter 13 includes a cutter block 14, a cutter seat 15, a cutter seat longitudinal displacement member 16, a slide seat 17, and a slide seat transverse displacement member 18. The vertical surface 7 and the inclined surface 8 are formed on the cutter block 14 at the same time, so that the cutter block 14 is a trapezoidal structure as a whole. The cutter seat 15 and the slide seat 17 are both U-shaped structures, but the side of the cutter seat 15 is complementary to the side of the slide seat 17, just accommodating the cutter block 14.

[0031] Furthermore, the knife block 14 is mounted on the knife seat 15, and the knife seat 15 is mounted on the slide 17 in a longitudinal sliding manner. The slide 17 is mounted with a knife seat longitudinal displacement member 16 for controlling the longitudinal displacement of the knife seat 15, and the slide 17 is mounted in the cutting knife groove 12 in a transverse sliding manner. The knife plate 11 is mounted with a slide transverse displacement member 18 for controlling the transverse displacement of the slide 17. The slide transverse displacement member 18 of the present invention adopts a hydraulic cylinder, which is mounted in the inner hole of the knife plate 11, and the output end of the hydraulic cylinder is connected to the slide 17 to control the transverse displacement of the slide 17. When the slide 17 is displaced in the transverse direction, it can also drive the knife seat 15 and the knife block 14 to be displaced in the transverse direction.

[0032] Here, the working principle of the cutter assembly 10 of the present invention is explained: Figure 2It is a schematic diagram of the cutter assembly 10 in working state. When the hydraulic telescopic assembly 9 drives the cutter assembly 10 to move up and down, the blade of the knife block 14 can remove the material from the substrate layer 1. Among them, the vertical projection of multiple cutters 13 can adapt to the final shape of the substrate layer 1. Therefore, by changing the inclination angle of the cutter 13 itself and the combination position between the cutters 13, the shape of the columnar prism structure 6 of the substrate layer 1 of different specifications can also be adjusted, which should be understood by those skilled in the art. The cutter 13 can move in the horizontal direction, so the distance between the columnar prism structures 6 can be adjusted. When the cutter 13 moves in the longitudinal direction, the depth of the tooth shape of the columnar prism structure 6 can be adjusted. When the angle of the cutter 13 is adjusted, the angle of the upper bevel of the columnar prism structure 6 can be adjusted to meet different actual needs and save the manufacturing cost of the cutter assembly 10.

[0033] In this embodiment, a spherical surface 19 is provided on the side of the blade block 14, and a ball groove 20 that cooperates with the spherical surface 19 is opened on the inner side of the blade seat 15. The blade block 14 can deflect around a vertical straight line, and the spherical surface 19 is rotatably installed in the ball groove 20, thereby realizing the adjustment of the angle of the blade block 14. Of course, the adjustment direction is preferably around a vertical straight line, so that the angle of the inclined surface 8 can be adjusted. After the angle adjustment of all blade blocks 14 is completed, the blade block 14 and the blade seat 15 are locked by a locking member 21 to avoid errors.

[0034] In this embodiment, the locking member 21 includes a screw, which is threadedly connected to a threaded hole on the cutter seat 15. The inner end of the screw is inserted into the threaded hole and abuts against the surface of the spherical surface 19. By setting the screw, it can be easily adjusted. A clearance groove 23 for the screw is provided on the inner wall of the cutter groove 12 to avoid interference.

[0035] In this embodiment, a support plate 24 is provided on the inner side of the slide 17, and the tool holder 15 includes a base plate 25 and limit plates 26 fixedly installed at both ends of the base plate 25. The ends of the support plate 24 are used to slide and limit the limit plates 26, which can increase the stability of the tool holder 15 when it moves relative to the slide 17.

[0036] In this embodiment, two adjacent slides 17 are slidably matched to reduce friction during sliding. Adjustment is convenient. Among them, balls can be installed between the slides 17, and a groove for installing the balls is provided on one of the slides 17, so that the balls are in contact with the outer surfaces of the two slides 17 at the same time, reducing the resistance of friction and increasing the stability of the structure during adjustment.

[0037] In this embodiment, the tool holder longitudinal displacement member 16 includes a screw 27 and a limit plate 28. The screw 27 is threadedly connected to the slide seat 17. The inner end of the screw 27 is fixedly connected to the limit plate 28. The limit plate 28 is rotatably installed in a rotating groove 29 opened in the tool holder 15. An open groove 30 is opened on the tool plate 11 for the screw 27 to make way.

[0038] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
