Description
Technical field
The utility model relates to electric wire field, more particularly, relates to a kind of mica tape gluing machine.
Background technology
Mica tape is to be main material by synthetic mica frying the mica paper that forms, then with adhesive, glass cloth is sticked on to one or both sides and make.Glass cloth is sticked on to be called " one-side band " of mica paper one side, all paste on two sides is " double-sided belt ".In manufacture process, after several layer of structure are bonded together, then dry through stove, then rolling, then cut into the belt of different size.
In electric wire, mica tape is often used as insulation and flame retardant coating at present, a kind of wire cable insulating material that protection electric wire can normally be used when high temperature and breaking out of fire.But various mica tapes not resistance to slippage except having insulation, fire resistance that existing market is sold, when electric wire rotates, easily sprains the metal in cable.The material that all can be wound around easy glide at present in electric wire improves the resistance to slip property between electric wire skin and mica tape.But the slippage meeting between electric wire skin and mica tape makes electric wire be difficult for stretching exhibition.
At present, in mica tape preparation process, need repeatedly gluing, and between different materials because adhesive property to binding agent is different, so need the mode of gluing also different, complicated situation is more, if the binding agent of selecting is incorrect, or the gluing mode of using is not right, can cause gluing inhomogeneous, cause the mica tape after compound to there is local performance deficiency.
Utility model content
In view of this, the utility model provides a kind of can have fire protecting performance, not only there is resistance to slip property but also can improve corrosion-resistant, the gluing machine of the mica tape that intensity is high, gluing is even, the mica tape excellent performance after compound.
In order to achieve the above object, the utility model provides following technical scheme:
A kind of mica tape gluing machine, comprise, frame, be arranged on Jiao Chi, upper glue roller, feeding roller, deflector roll and baking oven in described frame, described Jiao Chi comprises the first Jiao Chi and the second Jiao Chi, described the first inside, glue pond and top are respectively arranged with upper glue roller, and upper glue roller forms by two rollers that are in contact with one another; Described the first Jiao Chi has binding agent, and described the second Jiao Chi is connected with spray equipment, and described the second Jiao Chi is filled with organic pressure-sensitive gel;
Described feeding comprises and is arranged at the first feeding roller between described the first Jiao Chi and the second glue pond and is arranged at the second feeding roller between described the second Jiao Chi and baking oven; Described the first feeding roller is mica paper feeding roller, and described the second feeding roller is polytetrafluoroethylene feeding roller;
Described deflector roll contacts between two and forms one group, has two groups, is arranged at the first deflector roll between described the first feeding roller and the second glue pond, and is arranged at the second deflector roll between described the second feeding roller and baking oven;
Described oven interior also comprises three groups of pressure rollers.
The mica tape gluing machine that the utility model provides first carries out gluing by the first upper glue roller, by adhesive-coated in alkali-free glass cloth lower end, then by the first deflector roll and the first feeding roller feeding, mica paper and the alkali-free glass cloth that is coated with binding agent are carried out compound; Then by spray equipment to described mica paper surface spraying organic pressure-sensitive gel, then by the second deflector roll and the second feeding roller, polytetrafluoroethylene film and described mica paper and alkali-free glass cloth is compound, due to spraying is organic pressure-sensitive gel, so need to enter baking oven, and by the pressure roller in baking oven, cloth is compound, make organic pressure-sensitive gel that polytetrafluoroethylene and mica paper bonding is firm.The mica tape that the utility model provides can either improve intensity and corrosion resistance, has improved again the chemical stability of mica tape, and in addition, ptfe surface has good lubrification, can carry out slippage with electric wire skin.Last polytetrafluoroethylene has good insulation, resistance to elevated temperatures, while forming whole rear envelope curve with mica tape, can once complete traditional two procedures, because the organic pressure-sensitive gel providing in the utility model need to could be more even in spraying situation, so used spray equipment, and the extruding force of three pressure rollers once reduces in baking oven, so can make mica tape compound tightr.
