Description

Technical Field

[0001] This utility model relates to the field of environmentally friendly cardboard aluminum coating processing technology, and in particular to an aluminum coating equipment for environmentally friendly cardboard processing. Background Technology

[0002] Eco-friendly cardboard refers to cardboard products that utilize sustainably managed forest resources, employ a high proportion of recycled fibers, adopt clean production processes, and possess recyclable and biodegradable characteristics. Metallized film is produced by vacuum metallization, in which high-purity aluminum wire is evaporated into a gaseous state at high temperatures. When the plastic film passes through the vacuum evaporation chamber, the gaseous aluminum molecules precipitate onto the surface of the plastic film, forming a bright metallic film.

[0003] A search revealed an aluminum coating device with publication number CN210438822U, comprising a housing, end cap one, control groove, end cap two, storage groove, moving plate, square groove one, spring one, square groove two, T-shaped rod, spring two, inclined block, groove, limiting hole, handle, through groove, rotating rod, stop rod, magnetic block, and bearing. In this invention, the moving plate stretches spring one, generating elastic force. The moving plate then compresses the inclined block, causing it to move. This movement of the inclined block moves the T-shaped rod, further stretching spring two. When the inclined block aligns with the limiting hole, the elastic force of spring two causes it to move into the limiting hole, thus fixing the moving plate. The rotation of end cap two causes the stop rod to pass through the through groove. The rotation of the stop rod drives rotating rod two. When the stop rod rotates 90°, it engages with the magnetic block, thus fixing the stop rod. Simultaneously, the stop rod fixes the end cap. The bearing design facilitates the rotation of the rotating rod.

[0004] The device in the disclosed patent cannot pre-treat environmentally friendly cardboard. The surface of the cardboard is made of interwoven plant fibers, and there are a large number of pores on the surface of the paper fibers. The aluminum coating is very fragile, resulting in low processing quality and low practicality. Utility Model Content

[0005] In response to the technical problems in existing patents, such as the inability to pre-treat environmentally friendly cardboard during processing, the fact that the cardboard surface is made of interwoven plant fibers with numerous pores, resulting in a very fragile aluminum coating, low processing quality, and low practicality, this utility model provides an aluminum coating film device for processing environmentally friendly cardboard.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] The following is in conjunction with the appendix Figure 1-5 The present invention will be further described below.

[0018] To address the problems existing in the background art, this application proposes the following technical solution: An environmentally friendly paperboard processing aluminizing film equipment includes: a main body 1 and a pretreatment component 5; The equipment body 1 has slit differential suction boxes 2 fixedly installed on both sides. A support plate 3 is fixedly welded to the outer wall of the equipment body 1. A winding roller 4 is installed on the top of the support plate 3. The main body of the equipment 1 is equipped with an aluminum-plated film structure. In a high vacuum environment, the metal aluminum wire is heated and evaporated into aluminum atoms. The aluminum atoms are cooled and deposited on the surface of the cardboard to form a uniform and bright aluminum film. At the inlet and outlet of the slit differential pump box 2, there is a long and narrow cavity with multiple internal partitions, called the differential pump chamber. This cavity is divided into multiple independent small chambers by internal partitions. Each small chamber is connected to an independent vacuum pumping pipe and pump set. Each partition has a highly precise slit, the width of which is only slightly larger than the thickness of the environmentally friendly cardboard by a few tenths of a millimeter, to ensure that the cardboard can pass through smoothly, but the gap is extremely small. When the paper jam enters the inlet differential extraction chamber from the atmospheric side, it will bring in a large amount of air. First-stage evacuation: The outermost chamber has the highest pressure and is connected to a high-speed mechanical pump or Roots pump. It is responsible for removing most of the air brought in with the paper jam. The vacuum level here is relatively low. Second-stage evacuation: The pump unit in the intermediate chamber has a stronger evacuation capacity, removing most of the small amount of gas that leaked through the first slit, thus achieving a higher vacuum level in the chamber. The third stage of pumping: the innermost chamber, which faces the aluminum-plated main vacuum chamber directly. It uses a more powerful pump, such as a diffusion pump or a turbomolecular pump, to remove the last trace amount of gas, making its vacuum level infinitely close to that of the main vacuum chamber. Final effect: The number of gas molecules decreases exponentially with each slit they pass through, much like passing through a series of sluice gates. Most of the gas is blocked along the way, and the amount of gas that can enter the main vacuum chamber is negligible. The main pump in the main vacuum chamber can easily maintain the required high vacuum level.

[0019] like Figure 1-5 As shown, the pretreatment component 5 is installed on the slit differential suction box 2 on the inlet side of the main body 1 of the equipment. The pretreatment component 5 is used to perform base coating and drying pretreatment on the incoming cardboard.

[0020] The pretreatment component 5 includes an assembly structure 501 installed on one side of the slit differential suction box 2, a drying box 502 installed on one side of the assembly structure 501, a primer box 503 installed on one side of the drying box 502, and a primer structure 504 installed inside the primer box 503. The assembly structure 501 includes a positioning block 5011 fixedly welded to the top and bottom of a slit differential suction box 2, a positioning seat 5012 sleeved on the outside of the slit differential suction box 2, and a disassembly and assembly component 5013 installed inside the positioning seat 5012. The drying box 502 is fixedly welded to one side of the positioning seat 5012.

[0021] Furthermore, a socket groove 6 is provided on one side of the positioning seat 5012, a positioning groove 7 is provided on one side of the socket groove 6, and a reset groove is provided on one side of the positioning groove 7. The disassembly and assembly component 5013 includes a reset plate 9 fused to the inner wall of the reset groove by a reset spring 8, and a limiting post 10 and a disassembly and assembly post 11 fixedly welded to one side of the reset plate 9. The positioning block 5011 cooperates with the positioning groove 7, and a limiting hole 12 is provided on the positioning block 5011. The limiting hole 12 cooperates with the limiting post 10. The disassembly and assembly column 11 drives the reset plate 9 to squeeze the reset spring 8, and the reset plate 9 drives the limit column 10 to move, thereby controlling the relative position of the limit column 10 and the limit hole 12, and thus controlling the relative position of the positioning block 5011 and the positioning groove 7. This facilitates the disassembly and assembly of the positioning seat 5012 and the slit differential suction box 2, and facilitates the inspection, maintenance and replacement of the pretreatment component 5.

[0022] Furthermore, the primer structure 504 includes a rotating motor 5041 bolted to one side of the primer box 503, an anilox roller 5042 fixedly mounted on the output shaft of the rotating motor 5041 at both ends and rotatably mounted between the inner walls of the primer box 503, a back pressure roller 5043 rotatably mounted between the inner walls of the primer box 503, a coating tank 5044 mounted on the top of the bottom wall of the primer box 503, a scraper 5045 fixedly mounted on the top of the coating tank 5044, and a transmission component 5046 mounted on the back side of the primer box 503. The transmission component 5046 includes a first gear 13 fixedly sleeved on the outside of the rotating shaft of the anilox roller 5042 and a second gear 14 fixedly sleeved on the outside of the rotating shaft of the back pressure roller 5043. The first gear 13 and the second gear 14 mesh with each other, and the scraper 5045 is in contact with the anilox roller 5042.

[0023] Working principle: During use, the winding roller 4 is driven by the motor. The two winding rollers 4 work together to feed the environmentally friendly cardboard from the inlet side of the main body 1. Before passing through the slit differential suction box 2, the pretreatment component 5 begins to perform base coating and drying pretreatment on the cardboard. The positioning seat 5012 in the assembly structure 501 cooperates with the positioning block 5011 on the slit differential suction box 2 through the positioning groove 7. The limiting post 10 is inserted into the limiting hole 12 to achieve a stable connection, ensuring that the entire pretreatment component 5 remains stable during operation. When the cardboard enters the base coating tank 503, the rotating motor 5041 starts, driving the anilox roller 5042 to rotate. The anilox roller 5042 dips into the base coating liquid from the coating liquid tank 5044 and evenly coats the cardboard surface with the base coating liquid during the rotation. At the same time, the first gear 13 and the second gear 14 mesh, driving the back pressure roller 5043 to rotate, so that the cardboard is subjected to appropriate pressure during the base coating process to ensure the uniformity of the base coating layer. The scraper 5045 is in close contact with the anilox roller 5042 to scrape off excess base coating liquid and prevent over-coating. The cardboard after the primer coating is sent into the drying oven 502 and dried at an appropriate temperature to ensure that the primer coating can be cured quickly and firmly adhered to the surface of the cardboard. After drying, the cardboard continues to be conveyed forward and enters the aluminum film structure area. During this process, the slit differential vacuum box 2 is evacuated step by step to ensure that the aluminum plating process can be carried out smoothly in a high vacuum environment, thereby forming a uniform and bright aluminum film layer. The design of the entire equipment not only achieves efficient pretreatment of environmentally friendly cardboard, but also improves the ease of maintenance through the modular assembly structure 501, significantly enhancing processing quality and production efficiency.
