Description

Technical Field

[0001] The invention relates to the technical field of reflective film production, in particular to a reflective film capable of detecting leakage current and a production device thereof. Background Art

[0002] Reflective film is a flexible film that can retro-reflect light sources. Due to its excellent reflective effect, it is often used in traffic safety signs. By changing the production process, reflective films with different reflective effects can be made and used in different places. However, in many working environments, the function of reflective film is limited to safety warning.

[0003] For example, a Chinese invention patent document, publication number CN117936179A, discloses an early warning conductive reflective film. When the surface of the cable is damaged and causes power leakage, the electroluminescent body that penetrates the surface will come into contact with the current, causing the cable to pass along the electroluminescent body and be transmitted along the conductive layer to the ground wire or the neutral wire. When the current flows through the electroluminescent body, the electroluminescent body generates light, thereby warning people and allowing maintenance personnel to quickly discover that the cable has leakage, so as to replace the cable or repair it in time.

[0004] However, although the above-mentioned reflective film can form a loop using an external neutral wire or ground wire, an electroluminescent body and a leakage point, thereby emitting light when a leakage occurs, the structure is too complicated and the production cost is too high for a large number of reflective films to be laid. In addition, when connecting the loop, the conductive layer as a whole needs to be connected to the external low potential. Even if there is a continuous leakage, causing the electroluminescent body to emit light and being discovered by relevant personnel, it is still necessary to perform a leakage detection on the entire cable, which is of little help in leakage troubleshooting.

[0005] For example, the Chinese invention patent document, with the announcement number CN117656557B, discloses a production device for a reflective film with a micro-prism array structure. When the infrared sensor finds that the resin film is offset, the first electric roller on the left or right side is opened. When the left front infrared sensor detects it, the left first electric roller rotates backward to adjust the position of the resin film. The same applies to the other offsets. The flat plate can provide support when the scraper scrapes the coating.

[0006] In the above document, the translation processing is performed by the first electric roller. However, during the movement of the film, wrinkles will appear in the mold layer. If the flattening process is not performed, it will affect the appearance quality of the finished reflective film and cause uneven edge sizes. When the wrinkles are severe, bubbles will be mixed in the reflective film, affecting product quality. Summary of the invention

DETAILED DESCRIPTION

[0030] The present invention will be further described below in conjunction with the accompanying drawings: like Figure 1-Figure 10 As shown, this embodiment provides a reflective film capable of detecting leakage current, comprising a reflective layer 1, glass beads are arranged on the reflective layer 1, a transparent resin layer 2 is covered on the glass beads, high-temperature color-changing powder is added to the transparent resin layer 2, a backing layer 3 is arranged at the bottom of the reflective layer 1, a cushion layer 4 is arranged at the bottom of the backing layer 3, conductive powder is arranged in the backing layer 3 and the transparent resin layer 2, and the backing layer 3 also includes a flame retardant.

[0031] The transparent resin layer 2 is a photocurable resin and a photosensitizer. The transparent resin layer 2 is provided with pressing lines. During pressing, the degree of curing needs to be controlled so that the transparent resin layer 2 has a certain plasticity. Then, a secondary transparent resin coating is performed and then the transparent resin layer 2 is completely cured. The transparent resin layer 2 is coated with an anti-oxidation layer 201. The anti-oxidation layer 201 is used to protect the transparent resin layer 2 from being oxidized and discolored, thereby extending the service life of the reflective film. The reflective layer 1 is an aluminum-plated reflective film, which can increase the curing speed. The anti-oxidation layer 201 is composed of a polymethyl methacrylate film, which contains an antioxidant. The anti-oxidation layer 201 is covered with a protective layer 202, which can better protect the reflective effect of the reflective layer 1.

[0032] The reflective film layer can increase the function of the reflective film by adding conductive powder and high-temperature color-changing agent to the reflective film. When there is a leakage point around the reflective film, the reflective film at the corresponding leakage position can be broken down, and the appearance of the reflective film will change color, thereby helping relevant personnel to find the leakage point, and the flame retardant inside the reflective film can isolate the leakage after the leakage to prevent people from being electrically shocked. During production, glue needs to be coated on the cushion layer 4, and conductive powder and flame retardant need to be added to the glue. Then, the reflective layer 1 is pressed on the glue, and then a transparent resin with glass beads, conductive powder, and high-temperature color-changing powder is coated. After embossing, a secondary transparent resin coating is performed, and then an anti-oxidation layer 201 and a protective layer 202 for external protection are pressed on the transparent resin layer 2. The protective layer 202 usually uses a PE film.

[0033] The production equipment of the reflective film capable of detecting leakage current comprises a first frame shell 5, a second frame shell 6 and a third frame shell 7.

The first frame shell 5 is used to apply adhesive glue on the cushion layer 4 and press the reflective layer 1 after applying. The second frame shell 6 is used to add glass beads on the reflective layer 1 and press the texture of the reflective film at this time. Then, the transparent resin without glass beads is applied and flattened by the third frame shell 7.

The output shaft of the motor is connected to a laminating cylinder, and the laminating roller group 11 is used to laminar process the film layer. When necessary, an auxiliary heating device can be added for hot laminating. It is also necessary to add a power line at a suitable place to ensure the power supply of the equipment. A laminating roller group 11 is fixed between the side mounting plate 8 between the first frame shell 5 and the second frame shell 6. Curing lamps 12 are fixed on the side walls of the second frame shell 6 and the third frame shell 7. The curing lamp 12 can cure the material in the transparent resin layer 2. An embossing roller assembly 13 is installed on the side mounting plate 8 between the second frame shell 6 and the third frame shell 7. The structure of the embossing roller assembly 13 is basically the same as that of the laminating roller group 11. An embossed roller needs to be replaced between the upper and lower pairs of roller groups. During laminating, patterns can be pressed out on the film layer. Since there are glass beads in the liquid storage tank 9 on the second frame shell 6, the arrangement of the glass beads will affect the reflection effect during laminating, thereby forming patterns, which can increase the appearance style of the reflective film.

[0034] The liquid storage tank 9 on the first frame shell 5 is provided with adhesive glue, and the glue coating component 10 includes an upper horizontal plate 101 fixed in the first frame shell 5 by an electric lifting rod, a vertical rod is fixed at the bottom of the upper horizontal plate 101, a central component 102 is fixed at the bottom of the vertical rod, a scraper component 103 is rotatably mounted on the central component 102, a ring body is provided at one end of the scraper component 103, and a ring groove for rotating and clamping the ring body is provided on the central component 102.

The output port of the reflux pump 105 is connected with the corresponding liquid storage tank 9 through a pipeline. Guard plates are provided on both sides of the scraper component 103 to prevent excessive outflow of glue, so as to prevent excessive leakage of adhesive glue. A telescopic tube is provided at the bottom of the liquid storage tank 9 storing adhesive glue. The telescopic tube extends to the top of the scraper component 103 and extends into the sol tank through the end of the shunt tube. On this device, since there are two scraper components 103, a transverse tube is fixed at the bottom of the telescopic tube. Both ends of the transverse tube are provided with shunt tubes, and the ends of the shunt tubes extend into the sol tank respectively. In order to better fix the shunt tube, a support plate can be provided for structural support to fix the tube wall of the shunt tube and the scraper component 103. The shunt tube needs to use a hose. The output port of the reflux pump 105 can be directly connected to the bottom of the transverse tube, so as to facilitate the transportation of adhesive glue.

[0035] One end of the scraper component 103 is connected to a flattening mechanism 14, which includes a flattening cylinder 141 hinged to the scraper component 103, and the flattening cylinder 141 is sleeved on the bottom end of the lifting rod through a connecting plate, and a moving rod 142 is fixed to the top of the lifting rod, and the moving rod 142 is slidably connected to the bottom of the upper horizontal plate 101. The moving rod 142 is an electric rod, which can be driven by electricity to move at the bottom of the upper horizontal plate 101. The moving rod 142 is used to control the scraper and flattening to a suitable width range, so as to avoid wrinkles in the film layer during laying. When in use, the flattening cylinder 141 needs to be driven by external power, thereby driving the flattening cylinder 141 to rotate, and the outer wall of the rotating flattening cylinder 141 can flatten the film layer, and the outer wall of the flattening cylinder 141 can be provided with bristles to increase friction.

The source of the wind duct is the external environment, and when necessary, it can be connected to a dust suction device for cleaning the upper surface of the film layer. If there are impurities on the film layer, it will affect the reflective quality of the reflective film. Therefore, a negative pressure port close to the upper surface of the film layer can be provided on the film layer to absorb the impurities, which can help flatten the film layer.

[0037] When in use, the flattening cylinder 141 and the scraper component 103 form a rhombus, and the movement of the moving rod 142 on the upper horizontal plate 101 can drive the coverage range of the flattening cylinder 141 and the scraper component 103. When coating, the adhesive glue flows into the sol tank through the diverter pipe, and then is heated to enhance fluidity, and then flows to the cushion layer 4 through the leakage hole 104. A diverter groove is opened at the bottom of the leakage hole 104 to increase the uniformity of the outflow of the adhesive glue, and then the glue is continuously coated on the cushion layer 4. The excess adhesive glue can be sucked in by the reflux pump 105 and then reused, and a liquid pump and related valve components should be set in the corresponding liquid storage tank 9.

[0038] Then, the glue-coated cushion layer 4 can be pressed together with the reflective layer 1, and the liquid layers that need to be scraped in the subsequent second frame shell 6 and the third frame shell 7 can adopt the corresponding structure in the first frame shell 5. After the transparent resin layer 2 is coated, the transparent resin layer 2 can be cured by the curing lamp 12, and then the anti-oxidation layer 201 and the protective layer 202 are pressed on to complete the production.
