Manual laminating machine electrical heating minute surface roller
Technical field
The utility model relates to the printing machinery technical field, particularly a kind of manual laminating machine.Be the mirror roller that has electric heater unit that uses on a kind of manual laminating machine specifically.
Background technology
Overlay film is with the plastic sheeting behind the coating adhesive, is bonded together after heating, pressurization with paper printed matter, forms the product of paper unification.It is one of at present common paper printed matter post-press finishing technology.Printed matter through overlay film; because the much more surperficial thin and transparent plastic sheeting of one deck; the level and smooth more light in surface; not only improved the glossiness of printed matter; prolonged the service life of printed matter, simultaneously plastic sheeting plays protective effects such as waterproof, antifouling, wear-resisting, folding, resistance to chemical attack again.At present, common overlay film product has books and periodicals magazine, carton, carton, handbag, fertilizer bag, seed packet, adhesive label etc.Hot pressing temperature is adjusted according to situations such as printed matter ink film thickness, papery quality, climate changes, generally should be controlled at 60~150 ℃.The too high meeting of temperature surpasses the film tolerance range, and film etc. are subjected to Gao Re and are out of shape, and very easily makes the product lattice etc. that circumnutate, bubble, wrinkles, and the rubber rollers surface is easily scalded to decrease and is out of shape; Temperature is low excessively, and overlay film is not firm, easily delamination.
At present, carry out overlay film and add the manual laminating machine of most employings in man-hour.In order to heat and pressurization to plastic sheeting, manually the mirror roller structure of laminating machine is that electrothermal tube is installed in the mirror roller of rotation.The heat that electrothermal tube produces is by heat radiation and cross-ventilation conduction, for the mirror roller of manual laminating machine is heated.This structure mirror roller major defect is a non-uniform temperature, mirror roller surface some places temperature height; The some places temperature is low, causes to produce wrinkle film, foaming phenomenon behind the overlay film, and bonding quality is bad.
The utility model content
The purpose of this utility model is: a kind of manual laminating machine electrical heating minute surface roller is provided, can finishes overlay film processing, the mirror roller surface temperature is even, makes the compound film quality of manual laminating machine improve greatly.It is inhomogeneous to overcome the surface intensification of original mirror roller, thereby causes wrinkle film, foaming, the bad deficiency of bonding quality.
The technical solution adopted in the utility model is: manual laminating machine electrical heating minute surface roller, mainly form by mirror roller, electrothermal tube and brush assembly.Two ends at mirror roller are fixed with axle sleeve respectively, seal between axle sleeve and the mirror roller.At least one axle sleeve has centre bore, is fixed with an electrothermal tube in the centre bore of axle sleeve.Between electrothermal tube and the axle sleeve sealing ring is arranged, the mirror roller inner chamber is hedged off from the outer world, conduction oil is arranged, guarantee that the conduction oil of mirror roller inner chamber can not leak at the inner chamber of mirror roller.End at electrothermal tube has ring flange, and adopts bolt electrothermal tube to be fixed on the end of axle sleeve.End at axle sleeve also is fixed with brush assembly, for the electrothermal tube that rotates provides electric current.
With the electrothermal tube that mirror roller rotates, utilize brush assembly to realize turn-on current.The brush assembly structure is to be fixed with electric ring set in described electrothermal tube outer end, and there is annular electricity ring electric ring set outside, is fixed with electrode column on the end face of electricity ring, has to line between electrode column and the electrothermal tube to be connected.Electricity ring, electrothermal tube and mirror roller rotate synchronously.There is insulation sleeve the outside of electricity ring, and brush is installed on the insulation sleeve, and insulation sleeve is installed on the double-screw bolt, and insulation sleeve guarantees the insulation of brush and wallboard, and double-screw bolt is installed on the wallboard by adjusting plate, and brush forms sliding motion, brush external power supply with the electricity ring.Realize heating by this device to the mirror roller of rotation.
The beneficial effects of the utility model: the manual laminating machine electrical heating of the utility model minute surface roller can be finished overlay film processing, the mirror roller surface temperature is even, remain on optimum temperature for a long time, make the compound film quality of manual laminating machine improve greatly, it is inhomogeneous to overcome original mirror roller surface temperature, heat insulation effect is poor, thus problem such as the time wrinkle film that causes overlay film, foaming, bonding quality be bad.
