Cam link paper stopping mechanism

Abstract

The invention discloses a cam linkage-rod paper-blocking mechanism which comprises a casing unit, a transmission gear unit, two paper-charging rollers, a cam, a blocking plate and a revolving element. The casing unit comprises an upper casing and a lower casing. The upper casing is fixedly arranged on a machine body and the lower casing is arranged below the upper casing in a swinging manner. The lower casing is provided with a containing space and the transmission gear unit is arranged on the lower casing. The paper-charging rollers are arranged in the containing space and are connected with the transmission gear unit. One end of the cam is articulated with the transmission gear unit and the blocking plate is arranged on the upper casing in an up-and-down sliding manner and extends out from the lower casing. The revolving element is articulated with the upper casing and one end of the revolving element is connected with the blocking plate while the other end is connected with the cam. Therefore, the transmission distance between the paper-charging roller and the blocking plate can be shortened and then the expected transmission effect can be realized with less transmission components so as to effectively reduce cost.

Description

technical field [0001] The invention provides a cam-link paper stop mechanism, especially a cam-link paper stop mechanism applied to a business machine. Background technique [0002] Even in the modern era when the technology of communication-related industries is highly developed, although the concept of paperless operations has become common, the transmission of information still inevitably needs to be expressed through paper. After all, paper still has many irreplaceable advantages, such as Easy to carry and easy to modify and circulate. [0003] Generally speaking, business machines have the function of printing. However, in the trend of multi-function communication products, multi-function business machines with functions of scanning, printing, faxing and copying are derived from this and have been widely used. In various fields of society, such as companies, government agencies, academic institutions and even individuals, multi-functional business machines can meet th...

Problems solved by technology

[0008] The paper feeding roller and the baffle are respectively located at the opposite positions on the upper and lower sides of the body. Because the relative distance between the two is relatively far, it needs to pass through more transmission components to achieve the desired transmission effect, and using a large number of transmission components will It is directly reflected in the cost, and increases the difficulty and time of assembly, consumes a lot of man-hours, is not conducive to product production, and affects the profit of the enterprise

[0009] In order to cope with the long-distance transmission, the transmission long rod is used with more transmission components. After a long distance and through a variety of different types of transmission components, the transmission effect will be relatively sluggish, and the paper feed rollers and baffles will not work as expected. If it is activated within a short time, paper jams and other phenomena will occur, which will seriously affect the printing operation of the multi-functional business machine, delay the user's time, and reduce the business efficiency
