Abstract
The present invention relates to the pressurization mandrel of a kind of laser printer or photocopier, including metal cylinder and left and right enamel, along metal cylinder radially pin joint in left and right enamel is plugged on the through hole at metal cylinder two ends and through connecting pin, it is characterised in that: it is coated with skin of paint on the sidewall of described metal cylinder two ends.Metal cylinder two ends sidewall is coated with paint anticorrosive coat, can effectively stop the corrosion of metallic copper exposed two ends sidewall, improve service life and print quality, in the most corresponding connecting pin metal cylinder, pin joint counterbore is set, forge in pin joint counterbore and fill up aluminium, can effectively stop the loose or dislocation of connecting pin, improve safety in utilization.
Description
Technical field
The present invention relates to laser printer or photocopier field, a kind of laser printer or the pressurization of 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 parts.Fixing roller therein includes fixing 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 the fixing topping roll of halogen heating lamp as heating source, make toner particles fusing and merge into each other and to paper substrate
Infiltration, the most fixing bottom roll applies the certain pressure adhesive ability with increase toner particles, when printing paper leaves heating source, ink
Powder solidifies, and completes fixing.Fixing bottom roll is also called and adds dandy roll, conventionally employed grafting left and right, aluminum pipe two ends enamel knot
Structure, when heating source heats, adds dandy roll and 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 and adds dandy roll and blow, and there is potential safety hazard.And existing adding, carries spiral shell on the enamel of dandy roll employing left and right
Stricture of vagina pressure release prevents air expansion in body, and left and right enamel pin joint is stablized on aluminum pipe overall structure, to prevent from 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, affects printing quality；About Tong Shi
There is loose or dislocation hidden danger in the connecting pin of enamel, machine uses and there is quality, potential safety hazard.
Summary of the invention
For above-mentioned deficiency of the prior art, the invention provides a kind of simple in construction, firmly, can prevent burn into from becoming rusty
Erosion, without potential safety hazard, it is ensured that the laser printer of printing quality or the pressurization mandrel of photocopier.
The technical scheme is that the pressurization mandrel of a kind of laser printer or photocopier, including metal cylinder and left,
Right enamel, along metal cylinder radially pin joint, described metal cylinder in left and right enamel is plugged on the through hole at metal cylinder two ends and through connecting pin
On the barrel at two ends, upper and lower corresponding is provided with the pin joint counterbore of corresponding connecting pin, forges and fill up aluminium in pin joint counterbore.
Further, described metal cylinder, left and right enamel are iron metal cylinder.
Further, the left and right enamel outer circle wall of grafting metallic copper through hole is provided with lines groove.
Further, described skin of paint is anticorrosive coat.
The invention has the beneficial effects as follows: on the sidewall of metal cylinder two ends, be coated with paint anticorrosive coat, can effectively stop metal
The corrosion of copper exposed two ends sidewall, improves service life and print quality, and the most corresponding connecting pin metal cylinder sets
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.
Accompanying drawing explanation
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.
Detailed description of the invention
It is described further below in conjunction with drawings and Examples.
Shown in Fig. 1: the pressurization mandrel of a kind of laser printer or photocopier, including metal cylinder 1 and left and right enamel 3,4,
Along metal cylinder radially pin joint, metal cylinder 1 two ends in left and right enamel 3,4 is plugged on the through hole at metal cylinder 1 two ends and through connecting pin 6
Being coated with skin of paint 2 on sidewall, 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
The pin joint counterbore 5 of 6, forges in pin joint counterbore and fills up aluminium.
Improving further, metal cylinder, left and right enamel are iron metal cylinder.
Improving further, the left and right enamel outer circle wall of grafting metallic copper through hole is provided with lines groove.
Claims (4)
