Reflective film production device and production method

Abstract

The invention relates to the technical field of reflective film production, in particular to a reflective film production device and a production method. The reflective film production device comprises a base, a belt, a pressing plate and a controller. The base is in a cuboid shape, and sliding rails are fixedly connected to the two sides of the base; sliding blocks are slidably connected to the sliding rails; screw rods are rotatably connected between the two ends of the sliding rails; motors are installed at one ends of the sliding rails; output shafts of the motors are connected with one ends of the screw rods; the sliding blocks are in threaded connection with the screw rods; and triangular plates are fixedly connected to the opposite faces of the two sliding blocks; three rolling rodsare rotatably connected between the two triangular plates; the rolling rods are located at the corresponding corners of the triangular plates respectively; and a belt is connected among the three rolling rods in a transmission mode. According to the reflective film production device and the production method provided by the invention, the way that the motors drive the belt to move along the upperpart of a base layer is matched with the way that a No.2 electric push rod controls the pressing plate to extrude the base layer, so that glass microspheres can be evenly distributed at the upper endof the base layer, a light reflection performance of a reflective film is improved, and an actual application effect of the reflective film is further improved.

[0002] Reflective film is a retroreflective material that has been made into a film and can be directly applied; it is made of glass bead technology, microprism technology, synthetic resin technology, thin film technology, coating technology and micro-replication technology; usually white, yellow, Red, green, blue, brown, orange, fluorescent yellow, fluorescent orange, fluorescent yellow-green, and fluorescent red and fluorescent pink in foreign countries; especially for the production of reflective film of glass beads, the existing technology is becoming more and more mature. There are also various production methods, but the existing production methods generally have the problem of uneven dispersion of glass beads, which leads to poor reflective performance and affects the use effect.

[0003] There are also some technical solutions about reflective film production devices and production methods in the prior art. For example, a Chinese patent with application number CN201710160114.6 discloses a reflective film production device and production method, including glue tanks, glue tanks A smearing roller is arranged inside, a driven roller is arranged above the smearing roller, an upper pressing roller is arranged above the driven roller, a glass bead discharge device is arranged between the glue tank and the extrusion roller, an optical probe is arranged under the first substrate, and the first An optical sensor and feeding device are set above the substrate, a second substrate discharge device is set above the squeeze roller, a heating chamber and a cooling chamber are arranged behind the squeeze roller in sequence, and a leveling roller is arranged between the heating chamber and the cooling chamber ;After adopting the above structure and method, the glue can be spread evenly through the driven roller and the lower pressure roller, which improves the degree of adhesion, and the feeding is realized through the feeding device. The design of the light sensing device makes the feeding uniformity good and improves the reflection. performance; however, this technical solution still cannot solve the problem of uneven dispersion of glass beads in the production process of the reflective film, which affects the reflective properties of the reflective film, thereby causing the limitations of the solution
