Abstract
The invention relates to a pressurizing mandrel for a laser printer or duplicator. The pressurizing mandrel comprises a metal cylinder, a left enamel and a right enamel, wherein the left enamel and the right enamel are inserted into through holes in two ends of the metal cylinder and are pin-connected through a connecting pin along the radial direction of the metal cylinder; and the pressurizing mandrel is characterized in that paint layers coat the side walls of two ends of the metal cylinder. The anticorrosive paint layers coat the side walls of two ends of the metal cylinder, so that corrosion of the side walls of two exposed ends of the metal cylinder can be effectively prevented; the service life is prolonged; the printing quality is improved; and meanwhile, a pin-connected sink hole is arranged in the metal cylinder corresponding to the connecting pin and the pin-connected sink hole is forged and filled with an aluminum material, so that the connecting pin can be effectively prevented from loosening or dropping and the use security is improved.
Description
Technical field
The present invention relates to laser printer or photocopier field, the pressurization of specifically a kind of laser printer or photocopier
Use mandrel.
Background technology
The imaging transfer device of photocopier or laser printer includes photosensitive drums, developer roll, transfer device and fixing roller
Deng part.Fixing roller therein includes being fixed upper and lower roll, has been transferred the printing equipment of powdered ink pattern and upper and lower has rolled in fixing
Between roller, equipped with halogen heating lamp fixing topping roll as heating source, make toner particles melt and merge into each other and to paper substrate
Infiltration, is fixed bottom roll simultaneously and applies certain pressure to increase the adhesive ability of toner particles, when printing paper leaves heating source, ink
Powder solidifies, and completes fixing.Fixing bottom roll is also called pressurization rubber roll, enamel knot about conventionally employed aluminum pipe two ends grafting
Structure, when heating source heats, pressurization rubber roll heats up simultaneously, and its inner air tube expands, and aluminum pipe is different from left and right enamel material, expansion
Coefficient difference is easily caused pressurization rubber roll and blows, and there is potential safety hazard.And existing pressurization rubber roll carry spiral shell using on the enamel of left and right
Stricture of vagina pressure release prevents air expansion in body, and left and right enamel pin joint is stablized overall structure on aluminum pipe, to prevent assembling knot
Structure gets loose, but its body is chronically under high-temperature work environment, rubber-coated corrosion-free hidden danger on body circumference, but tube wall
Upper unshielded, there is burn into corrosion hidden danger, corrosion of metal powder easily falls on printing paper, affect printing quality；Left and right simultaneously
There is loose or dislocation hidden danger in the connecting pin of enamel, machine uses has quality, potential safety hazard.
Content of the invention
For above-mentioned deficiency of the prior art, the invention provides a kind of structure is simple, firm, can prevent burn into from becoming rusty
Erosion, no potential safety hazard are it is ensured that the pressurization mandrel of the laser printer of printing quality or photocopier.
The technical scheme is that：A kind of pressurization mandrel of laser printer or photocopier, including metal cylinder and left,
Right enamel, left and right enamel is plugged in the through hole at metal cylinder two ends and through connecting pin along metal cylinder radial direction pin joint, and its feature exists
In：It is coated with skin of paint on described metal cylinder two side wall.
Further, on the barrel at described metal cylinder two ends, upper and lower corresponding is provided with the pin joint counterbore of corresponding connecting pin, pin joint
Forge in counterbore and fill up aluminium.
Further, described metal cylinder, left and right enamel are iron metal cylinder.
Further, the left and right enamel outer circle wall of grafting metal copper vias is provided with lines groove.
Further, described skin of paint is anticorrosive coat.
The invention has the beneficial effects as follows：Metal cylinder two side wall is coated with paint anticorrosive coat, can effectively stop metal
The corrosion of the exposed two side walls of copper, improves service life and print quality, corresponds to simultaneously and sets in connecting pin metal cylinder
Put pin joint counterbore, forge in pin joint counterbore and fill up aluminium, can effectively stop the loose or dislocation of connecting pin, improve safety in utilization.
Brief description
Fig. 1 is present configuration schematic diagram.
In figure：Metal cylinder 1, skin of paint 2, left enamel 3, right enamel 4, pin joint counterbore 5, connecting pin 6.
Specific embodiment
It is described further below in conjunction with drawings and Examples.
Shown in Fig. 1：A kind of pressurization mandrel of laser printer or photocopier, including metal cylinder 1 and left and right enamel 3,4,
Left and right enamel 3,4 is plugged in the through hole at metal cylinder 1 two ends and through connecting pin 6 along metal cylinder radial direction pin joint, metal cylinder 1 two ends
Skin of paint 2 is coated with the wall of side, skin of paint is anticorrosive coat；On the barrel at metal cylinder 1 two ends, upper and lower corresponding is provided with corresponding connecting pin
6 pin joint counterbore 5, forges in pin joint counterbore and fills up aluminium.
Improve further, metal cylinder, left and right enamel are iron metal cylinder.
Improve further, the left and right enamel outer circle wall of grafting metal copper vias is provided with lines groove.
Claims (5)
