Description
Technical Field
The utility model belongs to the technical field of the duplicator, concretely relates to paper disc roller bearing subassembly.
Background
It is known that there is an important working component in a copier or a printer, namely, a paper-out component, and the performance and quality of the paper-out component are related to the performance of the whole machine, the stability of paper-out, the speed of paper-out, the error rate of paper-out, the smoothness of paper-out, and the like. The paper outlet assembly of the existing copier is often disordered in paper stacking and rolled by paper, especially, the paper is rolled by paper when the gram number of the used paper is light or the direction of paper fiber is vertical to the paper outlet direction, so that the paper is more easily rolled, the neatness of the stacked copies is influenced, and when the number of the copies is more, the paper outlet can be blocked, and the paper jamming phenomenon is caused.
To solve this problem, many manufacturers usually achieve the purpose of correcting the paper curl and paper disorder by adding a paper pressing block or a paper guiding rib to the paper outlet or improving the parameters of the fixing device itself to reduce the curling degree of the paper.
The structure of the current paper outlet assembly is as follows: two roll shafts are arranged in parallel up and down, a driving roll shaft is arranged above the two roll shafts, and a driven roll shaft is arranged below the two roll shafts; four paper feeding wheels are symmetrically arranged at the center of the roller shaft, and paper is discharged by friction.
The improved structure as the prior art is as follows: two raised creasing wheels extend out of the lower part between the left paper feeding wheel and the right paper feeding wheel respectively, the height of each creasing wheel is higher than that of the lower paper feeding wheel, and the cross section of each creasing wheel is arc-shaped. By the structure, when the copier discharges paper, the left and right protruding reinforcing ribs can be generated on the paper along the paper discharging direction, so that the rigidity of the paper is increased, the paper is ensured to be straight when discharging the paper, and the condition of rolling and disorder of the paper is reduced.
The measures can solve and overcome the defects of rolling and disorder in the drying process for the paper which is hard and thick, for example, more than 80 grams, but for the paper which is used in large quantities in China, 60 grams and 70 grams, the cost of the paper is low, the copying quality is good, the paper conforms to the principles of environmental protection and saving, and even has the advantage of reducing the storage and collection space.
Therefore, more effective measures are urgently desired in the field, especially in the domestic market, so as to better solve the defect.
