Lubricating pack specifically designed for paper shredders

Abstract

A lubricating pack specifically designed for paper shredders, including a piece of oiled paper saturated with lubricant placed between an upper and a lower plastic sheets or films that are subsequently fused around their peripheries to form a lubricating pack having a laminating construction. The lubricating pack is fed into the paper shredder through a paper inlet to the paper shredder under paper-feeding mode to be shredded by the paper shredder. Accordingly, the cutting blades of the paper shredder would be able to contact the lubricant contained in the oiled paper during the process of shredding the lubricating pack, so as to provide lubrication to cutting blades of the paper shredder thereby extending the lifespan of the paper shredder.

CROSS-REFERENCES TO RELATED APPLICATIONS [0001] Not Applicable STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT [0002] Not Applicable DESCRIPTION [0003] 1. Field of Invention [0004] This invention relates to a paper shredder, particularly to a lubricating pack specifically designed for paper shredders so as to provide lubrication to cutting blades of the paper shredder upon contact with the lubricant thereby extending the lifespan of the paper shredder. [0005] 2. Background [0006] It is widely known that paper shredders for shredding incorporate plural cutting blades and spacers passing through rotary shafts that are driven to rotate towards each other by a motor and gear box so as to shred paper passing through the rotary shafts into strips by shear forces. Shredders can be classed into two types, the stripe-cut shredders and crosscut shredders, according to the machine cutting style. The former shredders arrange cutting blades to the rotating cutter shafts in a mann...

Benefits of technology

[0009] It is a primary object of this invention to provide a lubricating pack specifically designed for paper shredders, which completely eliminates the use of the conventional lubrication system requiring complicated mechanical devices so as to reduce the number of components and labor cost, whereby lubrication of the cutting blades may be achieved without increasing the manufacturing cost of the paper shredders.

[0010] It is another object of this invention to provide a lubricating pack specifically designed for paper shredders, which eradicate the conventional oil drip adopted by the conventional lubrication system, that ensures uniform lubrication without worrying the hazards possibly resulted from excessive oil drip.

[0012] To achieve the above objectives and to overcome the drawbacks of the conventional art, this invention provides a lubricating pack specifically designed for paper shredders, including a. piece of oiled paper saturated with lubricant placed between an upper and a lower plastic sheets or films that are subsequently fused around their peripheries to form a lubricating pack having a laminating construction. The lubricating pack is fed into the paper shredder through a paper inlet to the paper shredder under paper-feeding mode to be shredded by the paper shredder. Accordingly, the cutting blades of the paper shredder would be able to contact the lubricant contained in the oiled paper during the process of shredding the lubricating pack, so as to provide lubrication to cutting blades of the paper shredder thereby extending the lifespan of the paper shredder.

Problems solved by technology

Regardless of being stripe-cut or crosscut shredders, the extended metal-to-metal contact and the high temperature generated in cutting paper due to concentrated stress that the cutting blades experience would dramatically reduce the cutting efficiency and shorten the lifespan of the paper shredders.

However, a closer look of the two patents reveals that, though they are able to serve the purpose of lubricating the cutting blades, the complicated constructions not only increase the manufacturing cost of the paper shredders, but also reduce the likelihood of commercializing the inventions.

For example, the use of timers, oil pumps and manifolds all require additional peripheral devices that significantly increase the manufacturing cost.

In addition, the use of oil drip to provide lubrication to the cutting blades requires precise control of oil drip amount and rate as well as lubrication uniformity, or resulting in insufficient lubrication or even fire hazards due to excessive oil drip.
