Embodiment Construction

[0026] The invention relates to a high wear-resistant paper feed wheel, which is composed of a plastic skeleton and a rubber wheel or sleeve covered thereon, characterized in that the rubber wheel or sleeve is made of a rubber composition, and the rubber Composition includes:

[0027] a. Rubber with good wear resistance, which is butadiene rubber, natural rubber or a combination of the two;

[0028] b. A vulcanization system that does not bloom and is suitable for the two rubbers in a. or combinations thereof;

[0029] c. One or more antioxidants;

[0030] The total weight of rubber in the rubber composition is 100 parts; the weight of the rubber vulcanization system is 5-10 parts, preferably 6-8 parts; the weight of the antioxidant is 0.5-3 parts, most preferably The best dosage is 1-2 servings.

[0031] The rubber vulcanization system is a mixture of zinc oxide, stearic acid, dibenzothiazole disulfide, N-cyclohexyl-2-benzothiazole sulfenamide and sulfur. in:

[0032] Th...

Abstract

The invention discloses a high abrasion-resisting paper feed roll which is composed of a plastic skeleton and a rubber wheel or a rubber sleeve sleeved on the plastic skeleton. The high abrasion-resisting paper feed roll is characterized in that the rubber wheel or the rubber sleeve prepared from rubber compositions, and the rubber compositions comprise: a. butadiene rubbers or natural rubbers with good abrasion performance, or the composition of the butadiene rubbers and the natural rubbers; b. a vulcanization system incapable of blushing which is suitable for the butadiene rubbers or the natural rubber, or the composition of the butadiene rubbers and the natural rubbers in a; and c. at least one antioxidant. The high abrasion-resisting paper feed roll has the advantages of extremely high abrasion-resisting performance, high friction force, no blushing and no pollution to paper, and is far more better than the commercial paper feed roll which is admitted to have the best quality.

Description

technical field [0001] The invention relates to a paper feed wheel in a paper pickup system such as a printer, a copier, and an all-in-one machine, and more particularly relates to a paper feed wheel for feeding a single sheet of paper into a copying or printing device. Background technique [0002] As we all know, in office equipment such as modern printers, copiers, fax machines, and all-in-one machines, a stack of paper is placed in the paper tray in advance. When working, a single sheet of paper is fed from the stack to the area for copying or printing. In this process, the separation and transmission of the paper are all achieved by the friction of the rubber wheel (sleeve) on the surface of the paper feed wheel. [0003] The material used to make the rubber wheel (sleeve) on the surface of the paper feed wheel must meet some strict and even conflicting requirements: [0004] 1. High friction force - During the service life, it keeps high friction force to ensure norma...
