Problems solved by technology

First, this processing method increases the complexity of the process and increases the cost; second, it may cause uneven surface texture, which affects the friction of the rubber wheel surface; third, the surface layer formed when the rubber wheel is formed is worn away, which will cause Accelerating the precipitation of some substances in the rubber wheel to the surface will also reduce the friction of the rubber wheel surface

Embodiment Construction

[0038] A method for manufacturing a paper feed wheel according to the present invention. The paper feed wheel is composed of a plastic skeleton 2 and a rubber wheel 1 sleeved thereon. Teeth 11, the rubber wheel 1 is formed by one-time compression vulcanization, and does not need to be ground again.

[0039] Described rubber wheel 1 is made of rubber composition, and this rubber composition comprises:

[0040] (1) Rubber with good wear resistance, which is a combination of butadiene rubber and natural rubber;

[0041] (2) A rubber vulcanization system, suitable for the butadiene rubber and natural rubber composition, which can fully vulcanize the rubber composition without causing surface blooming;

[0042] (3) At least one antioxidant, including at least one physical antioxidant, in addition to the antioxidant effect, it can also play a role in helping to release the rubber after vulcanization;

[0043] (4) At least one reinforcing filler, an appropriate amount of reinforcin...

Abstract

The invention discloses a paper feeding wheel and a manufacturing method thereof. The paper feeding wheel consists of a plastic framework and a rubber wheel sleeved on the plastic framework, wherein the rubber wheel is made of a rubber composition; and the rubber composition comprises rubber with high wear resistance and strength, an effective rubber vulcanizing system, more than one antioxidants, and a proper amount of reinforcing filler and softening agent, wherein the effective rubber vulcanizing system is suitable for a composition of butadiene rubber and natural rubber; one of the more than one antioxidant has a function of assisting in demoulding after rubber is vulcanized; and the proper amount of reinforcing filler and softening agent can improve the strength of the rubber wheel and cannot obviously improve hardness. The invention has the advantages that: the manufacturing process is simple, and the rubber wheel is formed by a mold through one-time compression moulding, and is not required to be processed; the surface of the paper feeding wheel is hardly subjected to frost spray; and the frictional property of the surface of the paper feeding wheel can be kept for a long time.

Description

technical field [0001] The present invention relates to a paper feed wheel in paper pick-up systems such as printers, duplicators, and all-in-one machines, and more particularly relates to a paper feed wheel for feeding a single sheet of paper into a copying or printing device and a manufacturing method thereof. 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 pre-placed in the paper tray, and when working, a single sheet of paper is fed from the stack to the area where copying or printing is performed. In this process, the separation and transmission of the paper are realized by the friction of the rubber wheel on the surface of the paper feed wheel. [0003] Generally speaking, when the paper feed wheel is initially designed, the surface of the rubber wheel will generally have a rough texture in order to obtain high friction. Most of the paper feed wheels currently...
