Description

TECHNICAL FIELD

[0001] The present application relates to a rough oil surface aluminum foil composite tape production line which can form a rough surface with small friction coefficient on the surface of aluminum foil or plastic film, reduce material and energy consumption, and realize fast coating and drying speed and full coverage without coating dead angle. BACKGROUND

[0002] CN102347117B, entitled "lubricating treatment method of aluminum foil polyester composite tape", includes the following steps: (1) uniformly coating a lubricant on the surface of the aluminum foil polyester composite tape; (2) drying the above-mentioned lubricating treated material at 50-100°C; the volume ratio of the lubricant is soybean oil oxidized: diluent = 1:0.5-2.5, and the specific ratio is adjusted according to different coating amounts. The diluent is an ester or ketone solvent, specifically, the ester solvent is methyl acetate, ethyl acetate or propyl acetate; the ketone solvent is acetone, methyl butanone or methyl isobutyl ketone. The viscosity of the soybean oil oxidized is 350-500. In step (1), the uniform coating method is to uniformly coat the lubricant on the surface of the aluminum foil polyester composite tape by a 60-80 line / cm anilox roller, and the equipment operating speed is 40-150 m / min. The diluted lubricant is uniformly coated on the surface of the aluminum foil or plastic film by a 60-80 line / cm anilox roller, and the final coating amount after drying is controlled at 0.2-0.5 g / m 2 The lubricated aluminum foil improves the speed of the wire and cable during spinning and reduces the possibility of aluminum foil breakage. Compared with the aluminum foil without surface treatment, the friction coefficient of the aluminum foil surface is reduced by 50%, and the stability of the friction coefficient is good. However, in actual application, it is difficult to achieve uniform coating by using the 350-500 viscosity soybean oil oxidized anilox roller on the surface of the aluminum foil or plastic film, because the oil consumption of the anilox roller cannot be quantitatively controlled, especially during the rotation of the anilox roller, the oil coated on the surface of the aluminum foil or plastic film cannot be uniform, and a rough surface with the smallest friction resistance cannot be formed on the surface of the aluminum foil or plastic film, so the possibility of aluminum foil breakage cannot be avoided. In addition, material is wasted. In order to achieve relatively uniform coating (which is actually difficult to achieve) of the anilox roller on the surface of the aluminum foil or plastic film, the anilox roller must be filled with lubricating oil. As a result, the coating is too thick, which not only wastes material but also directly increases the friction coefficient. Because the lubricating oil is too thick to form an elastic surface, the resistance is large, which is not conducive to the over-molded cable and optical cable, and the energy consumption is large, which requires three-stage oven baking. Moreover, the use of the anilox roller for coating on the surface of the aluminum foil or plastic film is prone to leakage, and the equipment operating speed is 40-150 m / min, which is low in efficiency. Furthermore, full coverage cannot be achieved, and the two side edges of the aluminum foil or plastic film cannot be coated. SUMMARY

[0003] Design purpose: to avoid the shortcomings in the background art, design a kind of both can form the rough surface of over-mold friction coefficient on the surface of aluminum foil or plastic film, can reduce material and energy consumption, and coating, drying speed is fast, can realize the rough oil surface aluminum foil composite belt production line of aluminum foil or plastic film all-around without coating dead angle.

[0004] Design Scheme: To achieve the above design objectives, 1. The design of having a layer of oil microparticles roughening the surface of the aluminum foil composite tape is one of the technical features of this invention. The purpose of this design is that, although in the background technology, the reason why the oil film formed after drying when lubricant is applied to the surface of the aluminum foil polyester composite tape has a lower coefficient of friction than the surface of the aluminum foil polyester composite tape without lubricant is only due to the lubrication coefficient of the lubricant itself, not due to the surface structure of the aluminum foil composite tape. This cannot meet the needs of rapid overmolding and wrapping. Therefore, when the overmolding and wrapping speed of cables and optical cables is slightly fast, the aluminum foil composite tape will break. Therefore, in the structural design of the aluminum foil composite tape, the present invention, based on the existing aluminum foil composite tape, adheres a layer of atomized oil microparticle rough surface structure to the tape surface. After the atomized oil microparticles solidify, an oil microparticle rough surface is formed on the surface of the aluminum foil composite tape. Since the oil microparticles solidified on this rough surface have varying diameters and are uneven under microscopic examination, when the tape is used to wrap cables or optical cables, the solid microparticles on the rough surface form multi-point contact with the wrapping surface, rather than surface contact. Compared with the prior art, this greatly reduces the coefficient of friction, ensuring that the entire roll of oil microparticle rough surface aluminum foil composite tape will not break regardless of how it is wrapped with cables or optical cables. 2. The design of placing a layer of oil-mist-cured oil microparticle rough surface on the cut (end) surface of the aluminum foil composite tape is the second technical feature of the present invention. The purpose of this design is that the cutting surfaces on both sides of the aluminum foil composite tape are the surfaces with the highest coefficient of friction (highest resistance). However, due to the limitations of the anilox roller in the background technology, coating can only be applied to one or two sides of the aluminum foil composite tape, and it is not possible to coat the cutting (end) surfaces on both sides of the aluminum foil composite tape. However, during the overmolding process of cables and optical cables, when the aluminum foil composite tape is overmolded to wrap the cables and optical cables, the cutting (end) surfaces on both sides of the aluminum foil composite tape will inevitably come into contact with and overlap the surface of the aluminum foil composite tape. However, because the cutting end surfaces and the edge of the end surfaces on both sides of the aluminum foil composite tape not only have high resistance (high coefficient of friction), but their edge itself is like a knife edge. When the cutting end edges on both sides of the aluminum foil composite tape come into contact with the surface of the aluminum foil composite tape, tangential, pulling, and obstructive phenomena are very likely to occur, directly leading to the breakage of the aluminum foil composite tape. This restricts the wrapping length of the cables and optical cables, making it impossible to achieve the purpose of uninterrupted wrapping of cables and optical cables with the entire roll of aluminum foil composite tape. To address this, the present invention incorporates an oil mist microparticle rough surface layer on the slit surface of the aluminum foil composite tape, solving the problem of high frictional resistance at the slit surface of the aluminum foil composite tape. This enables the aluminum foil composite tape to achieve rapid and uninterrupted wrapping of cables and optical fibers from all directions without any blind spots. 3. The design of the oil mist adhesion device is the third technical feature of the present invention.The purpose of the design is that the present application is provided with a bubble atomizing nozzle (i.e. a bubble atomizing burner) on the atomizing box with aluminum foil inlet and outlet, the nozzle is provided with compressed air or steam in a special structure channel to form a large number of bubbles, the bubbles are broken after a series of processes such as movement, deformation and acceleration at the nozzle outlet to form liquid droplets with very small and high uniformity, the liquid mist fills in the atomizing box, when the aluminum foil composite tape passes through the atomizing box filled with liquid mist, a layer of atomized oil particles with very good uniformity is attached to all surfaces of the aluminum foil composite tape, and the atomized oil particle layer can be solidified to form an oil particle rough surface after passing through the drying channel to reduce the friction coefficient of the surface.4. The design of the atomizing oil recovery device at the outlet of the atomizing box is the fourth technical feature of the present application. The purpose of the design is that the atomizing box inlet (aluminum foil composite tape inlet) is provided with a sealing curtain, the sealing curtain is an upper and lower elastic curtain, the curtain lip of the upper and lower elastic curtain is in closed cooperation with the surface of the aluminum foil composite tape, and the purpose is to prevent the atomized oil particles in the atomizing box from leaking out without damaging the surface of the aluminum foil composite tape, but the atomizing box outlet is designed as a strip-shaped opening structure, the purpose is to make the outlet not touch the aluminum foil composite tape with atomized oil particles (not damage the atomized oil particle layer on the surface of the aluminum foil composite tape) to enter the drying channel in a natural state to form an oil particle rough surface.5. The design of using epoxy soybean oil as the oil particle rough surface base material is the fifth technical feature of the present application. The purpose of the design is that the English name of epoxy soybean oil is epoxidized soybean oil, which is abbreviated as ESO, and the chemical formula is (RC2H2OR'COO)3C3H5. It is a light yellow viscous oil at room temperature, non-toxic. The boiling point is 150℃ (0.53 kPa), soluble in most organic solvents and hydrocarbons, insoluble in water, not only has excellent heat resistance, light resistance and compatibility, but also has excellent film forming, dispersing and adsorbing properties. The present application uses the characteristics of epoxy soybean oil as the oil particle rough surface base material, which can form liquid droplets with very small and high uniformity in the bubble atomizing nozzle under the condition of organic solvents and hydrocarbon solvents, and can meet the requirements of rapid solidification in the high temperature drying channel of 105℃-200℃ while not damaging the oil particle rough surface.6. The open structure design between the outlet of the oil atomizing adhesion device and the drying channel is the sixth technical feature of the present application. The purpose of the design is that the organic solvent is an organic compound with small molecular weight, which is in liquid state at room temperature and pressure, and has high volatility. When it is combined with epoxy soybean oil as a diluent, the volatile gas generated can accelerate the rapid volatilization and preliminary setting of the atomized oil particle surface of the aluminum foil composite tape under the action of the open structure.7. The design of the air cooling device between the drying channel and the winding guide shaft is the seventh technical feature of the present application.The purpose of the design is that the temperature of the oil particle surface aluminum foil composite belt after drying in the drying channel is relatively high, the rough surface of the oil particle has a large amount of heat, and if the heat is not dissipated, the heat directly affects the bonding strength between the aluminum foil and the film when the oil particle surface aluminum foil composite belt is wound into a shape. The air cooling device provided between the drying channel and the winding guide shaft not only solves this problem well, but also removes the volatile gas twice.8. The design of the oil atomization adhesion device and the drying channel in the negative pressure suction cover is the eighth technical feature of the present application. The purpose of the design is that when the negative pressure suction cover covers the oil atomization adhesion device and the drying channel, the volatile gas generated during the production process can be transported to the air purifier through the pipeline on the negative pressure suction cover, realizing harmless gas emission.9. The design of the blowing cover on the winding roller is the ninth technical feature of the present application. The purpose of the design is that the blowing cover on the winding roller is an arc structure, and a plurality of air outlets are opened in the arc-shaped blowing cover. The cold air flow formed not only covers half of the rough oil surface aluminum foil composite belt of the winding roller, but also blows to the back rough oil surface aluminum foil composite belt after passing through the front half of the rough oil surface aluminum foil composite belt, greatly improving the cooling efficiency.10. The design of the tension sensor on the rough oil surface aluminum foil composite belt winding roller is the tenth technical feature of the present application. The purpose of the design is that the running of the aluminum foil composite belt on the unwinding roller is driven by the rough oil surface aluminum foil composite belt wound on the winding roller. When the traction force of the winding roller is greater than the breaking force of the aluminum foil composite belt, the aluminum foil composite belt will be pulled apart. Therefore, a tension sensor is arranged on the rough oil surface aluminum foil composite belt winding roller. The tension sensor detection value can be dynamically transmitted to the PLC controller, and the PLC controller controls whether the motor for driving the rough oil surface aluminum foil composite belt winding roller works according to the preset tension value. When the tension value of the rough oil surface aluminum foil composite belt is greater than the preset tension value, the PLC controller issues a warning and instructs the motor to stop working to prevent the rough oil surface aluminum foil composite belt from being pulled apart. At the same time, a damper is arranged on the unwinding shaft roller, which can prevent the aluminum foil composite belt from being relaxed due to the continuous rotation of the unwinding roller.

[0005] Technical scheme: A rough oil surface aluminum foil composite belt production line, comprising a PLC controller, an aluminum foil composite belt unwinding roller, an oil atomization spraying device, a drying channel, a winding guide shaft, and a rough oil surface aluminum foil composite belt winding roller.

[0006] Compared with the background art, the rough oil surface aluminum foil composite tape production line is implemented, so that the rough oil surface aluminum foil composite tape over-mold coating surface realizes all-around rough oil surface coating. Not only the friction coefficient is small when the cable and optical cable over-mold, and the blocking phenomenon does not occur, but also the material and energy consumption required by the rough surface is reduced, and the over-mold coating efficiency is high, the rough oil surface aluminum foil composite tape is not broken, the drying speed is fast, the environment is protected, and there is no harmful gas leakage. The test test data are as follows:
