Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of decorative film, more particularly, it relates to a high-weatherability decorative film and processing system. BACKGROUND

[0002] The decorative film is a new type of decorative material made of high molecular polymer as raw material, adding various additives, and being compounded by calendering. It can be compounded with wood, plastic board, aluminum plate, iron plate and other substrates to make multi-purpose decorative materials, and is widely used in various fields. The pressure-sensitive adhesive layer, coloring layer and transparent layer of some existing decorative films are relatively soft, which leads to the deformation of the decorative film. In addition, the tensile strength of the decorative film is not high, and the finished product decorative film is easily over-pulled during conveying and traction, resulting in irreversible deformation.

[0003] After searching, a high-weatherability non-color-changing decorative film and processing equipment (CN116238219B) is disclosed, which relates to the technical field of decorative film and comprises a decorative film including a base film layer one, a thermoplastic resin layer, a reinforcing layer and a base film layer two. The base film layer one, the thermoplastic resin layer, the reinforcing layer and the base film layer two are sequentially glued together by hot pressing. By hot pressing the reinforcing layer in the decorative film, the problem of deformation of some existing decorative films is solved.

[0004] However, the above-mentioned high-weatherability non-color-changing decorative film has weak simulation texture. When the decorative film is unfolded, the front and back surfaces of the decorative film are mutually adhered, affecting the use. At the same time, the base film layer one, the thermoplastic resin layer, the reinforcing layer and the base film layer two of the above-mentioned decorative film are sequentially glued together by hot pressing, which is a relatively complicated operation process, reducing the delivery efficiency. SUMMARY

[0005] In view of the deficiencies of the prior art, the purpose of the present application is to provide a high-weatherability decorative film and processing system. By printing an ink layer on the surface of the first polyvinyl chloride base film, the simulation texture of the decorative film is improved, and the variety of materials suitable for covering is widened. By providing a net-like woven reinforcing layer, the anti-deformation ability of the decorative film is improved. By coating a polyurethane resin chemical separation layer on the bottom surface of the second polyvinyl chloride base film, when the cylindrical product is opened, the front and back surfaces of the decorative film do not adhere to each other, improving the practicality of the decorative film. By the linkage cooperation between the components, synchronous hot pressing and gluing operation of the upper film part, the thermoplastic resin layer and the lower film part is realized, optimizing the operation process and improving the processing efficiency of the decorative film.

The glue on is coated on the bottom surface of the thermoplastic resin layer 2; since a mesh woven reinforcement layer 6 is provided on the lower membrane portion 8, a sufficient amount of glue is required to fill the grid on the mesh woven reinforcement layer 6 with the adhesive layer. The screw tube 40 is rotated to drive the glue baffle 39 at its bottom to rise and fall along the process groove, and the distance between the glue outlet 38 and the surface of the thermoplastic resin layer 2 is adjusted, thereby controlling the thickness of the glue coated on the surface of the thermoplastic resin layer 2. The glue inside the transfer box 35 is coated on the surface of the moving thermoplastic resin layer 2 through the glue outlet 38.

[0061] During the lamination process of the two sets of rubber lamination rollers 19, excess glue on the surface of the thermoplastic resin layer 2 is squeezed out, and most of the overflowed glue is synchronously conveyed away by the conveyor belt 76. The glue on the driven conveyor belt 76 is scraped off by the second scraper 79 and falls into the collection box 17 for collection; the two sides of the decorative film that has completed the lamination are slid between the upper connecting plate 80 and the lower connecting plate 82, and are scraped off by the third scraper 81, thereby improving the quality of the decorative film. The glue scraped off on both sides of the decorative film is retained in the collection box 17 through the guide groove 83 for collection.

[0062] The sliding sleeve 55 is internally provided with a sliding block, and the side surface of the sliding sleeve 55 is in sliding fit with the side surface of the glue storage box 42. The reciprocating screw rod 51 is a form of three-dimensional cam pair, which is characterized by two thread grooves with the same pitch and opposite rotation directions, and the two ends are connected by an over curve. Through the rotation of the reciprocating screw rod 51, the side surface of the screw groove pushes the sliding block arranged in the screw groove to make axial reciprocating movement. Through the arrangement of the one-way valve on the liquid suction pipe 68, the glue in the glue storage box 42 can only be sucked into the piston cylinder 65 through the liquid suction pipe 68. Through the arrangement of the one-way valve on the liquid discharge pipe 69, the glue in the piston cylinder 65 can only be discharged into the inside of the transfer box 35 through the liquid discharge pipe 69.

[0063] The glue roller 44 drives the first sprocket 62 to rotate in the process of rotation, drives the second sprocket 63 to rotate through the chain 64, and then drives the reciprocating screw rod 51 to rotate, and further drives the piston part 53 to slide reciprocally, so as to realize the periodic quantitative delivery of the glue in the inside of the transfer box 35.

[0064] When the piston part 53 slides towards the direction away from the extension rod 70, the piston 67 is driven to slide along the piston cylinder 65 to send the glue into the inside of the transfer box 35 through the liquid discharge pipe 69. When one end of the sliding sleeve 55 is pressed on the corresponding pressure sensor 52, the control starts the second servo motor 49 to drive the rotating rod 47 to rotate, so that the semi-guide column 48 rotates to separate from the ball head 59. Under the elastic force of the return spring 60, the square rod 58 is driven to slide along the support plate 56 to rise, and the ball head 59 is tightly pressed on the side surface of the rotating rod 47. In this process, the first scraper 61 is separated from the glue scraping plate 54, so as to ensure the one-way glue removal of the first scraper 61 and the glue scraping plate 54.

[0065] When the piston part 53 slides towards the direction close to the extension rod 70, the glue in the glue storage box 42 is sucked into the inside of the piston cylinder 65 through the liquid suction pipe 68. In this process, the first scraper 61 is separated from the glue scraping plate 54. When the other end of the sliding sleeve 55 is pressed on the other pressure sensor 52, the control starts the second servo motor 49 to drive the rotating rod 47 to rotate, so that the rotating rod 47 rotates to separate from the ball head 59. Under the elastic force of the return spring 60, the square rod 58 is driven to slide along the support plate 56 to descend, and the ball head 59 is tightly pressed on the side surface of the semi-guide column 48. In this process, the first scraper 61 slides to descend and is pressed on the surface of the glue scraping plate 54. In the process of the piston part 53, the first scraper 61 removes the glue on the surface of the glue scraping plate 54, so as to improve the use quality of the glue roller 44.

[0066] In the process of reciprocating sliding of the piston part 53, the guide ball 73 is driven to reciprocally slide along the spiral groove 71 on the extension rod 70, so as to drive the extension rod 70 to periodically rotate forward and backward, and further drive the stirring shaft 36 and the stirring plate 37 to synchronously periodically rotate forward and backward, so as to stir the glue in the inside of the transfer box 35, and improve the glue coating effect.
