Description
Technical Field
The invention relates to a chain hole paper bending and changing mechanism and a paper tray using the same, which are used for printers, in particular to a paper taking tray or a paper discharging tray of a needle printer.
Background
At present, in the field of printing of the sprocket hole paper, the sprocket hole paper is different from the ordinary paper, and because the sprocket hole and the teeth are arranged on two sides of the sprocket hole paper, after the sprocket hole paper is punched and the teeth are snapped, the vicinity of the sprocket hole and the teeth can become uneven, the phenomenon of thickening on two sides can occur after the stacking of the sprocket hole paper, and along with the stacking of the sprocket hole paper, the sprocket hole paper can be in a state of being bent downwards in the middle of the transverse direction, namely gradually in a U-shaped state, as shown in fig. 1 and 2.
When the printer takes paper, the chain hole paper needs to curl in the longitudinal direction, the softness of the chain hole paper in the longitudinal direction is beneficial to the carrying out of the chain hole paper (as shown in a paper taking path in fig. 3), under the condition of a normal plane tray, as the paper is deformed in the transverse direction, certain difficulty is caused to be generated in the longitudinal direction, particularly under the condition that the paper taking box is limited in space, the paper takes up most of space in the condition of full stacking, the space for carrying out the paper is small, the space of the paper tray is limited, and under the condition that the paper taking is difficult;
when the paper is discharged, as the chain hole paper pile is in the transverse direction, the middle part of the chain hole paper pile is downwards bent, the rough parts such as the chain holes and the teeth are at the uppermost part, and the next chain hole paper has high probability of being rubbed to the chain holes and the teeth in the paper discharge process, so that normal paper discharge cannot be performed. As shown in fig. 4;
the prior art has the following solutions to solve the above problems:
1. when discharging paper, a roll shaft or a paper pressing plate is added on the paper to press the paper to compensate the bending degree of the chain hole paper in the transverse direction.
2. When the paper is taken, the space for taking the paper is enlarged, so that the chain hole paper has enough space to release transverse bending deformation when the paper is fed.
The two solutions not only require a larger paper taking space, but also have complex structures and increased cost, and do not thoroughly solve the problems.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a chain hole paper bending and changing mechanism, which can relieve the deformation degree of U-shaped deformation of the chain hole paper in the transverse direction under the condition of fully loading and piling up the chain hole paper, effectively compensate and prevent the transverse deformation of bill paper piles, prevent the situation that the two sides of the chain hole paper piles are high and the middle is low, be favorable for longitudinal bending and solve the problem of difficult longitudinal paper taking in a limited space; meanwhile, when the device is used for a paper discharge tray, the phenomenon that paper discharge is not smooth and the stacking effect is seriously influenced due to the fact that the rough parts are propped against two sides is avoided.
In order to solve the technical problems, the technical scheme of the invention is as follows: a chain hole paper bending variation mechanism for a paper tray of a printer, comprising:
and a member disposed at the bottom of the chain hole sheet stack, contacting the bottom surface of the lowermost chain hole sheet, and protruding in the direction of the chain hole sheet stack, for compensating for a state in which the chain hole sheet stack is bent upward at the middle in the longitudinal direction and/or bent downward at the middle in the transverse direction.
Further, the member extends in the lateral direction of the chain hole sheet stack so as to be used for bending upward the middle of the chain hole sheet stack in the longitudinal direction.
Further, the member extends in the longitudinal direction of the chain hole sheet stack so that the member compensates for a state in which the chain hole sheet stack is bent downward in the middle of the lateral direction.
Further in order to better compensate for the bending of the chain hole sheet stack, the height H of the member is calculated as follows: h= (L2-L3)/K; wherein L2 is the distance between the highest point of the bottom surface of the chain hole paper stack after the component acts and the bottom surface of the component; l3 is the distance between the lowest point of the bottom surface of the chain hole paper stack after the component acts on the bottom surface of the component; k is 1-250.
Various shapes and structures of the component are further provided, wherein the component is a cylinder or a semi-cylinder or a cuboid or a triangular prism platform or a polygonal prism.
Further, in order to simultaneously satisfy the upward bending of the middle of the chain hole sheet stack in the longitudinal direction and the downward bending of the middle of the chain hole sheet stack in the transverse direction, the member is of a spherical structure or a hemispherical structure.
Further, the member is fixedly provided on the paper tray.
Further, the member and the paper tray are integrally formed.
Further provided is a means for arranging the member, which is a stamped protruding member of the paper tray stamped out with sheet metal.
After the technical scheme is adopted, the invention has the following beneficial effects:
(1) If the member has a function of compensating for a state in which the middle of the chain hole paper stack is bent downward in the lateral direction, that is, the member is placed in the longitudinal direction, it can compensate for the U-shaped stack of the chain hole paper in the lateral direction when it is used in the paper discharge tray, so that the upper surface of the chain hole paper stack is smoothed or inverted U-shaped, preventing the re-stacked chain hole paper from rubbing to both sides thereof; when the chain hole paper taking device is used in a paper taking tray, the U-shaped stacking of the chain hole paper in the transverse direction can be compensated, so that the upper surface of the chain hole paper stacking tends to be smooth, and the uppermost chain hole paper is difficult to take out under the condition that the paper is fully filled, so long as the uppermost chain hole paper is ensured to be smooth under the condition that the uppermost chain hole paper is fully filled, the stacking height is reduced along with paper taking, the residual space is larger and larger, and even an inverted U-shaped state is generated, the chain hole paper taking device is safer;
(2) If the member has a function of bending up the middle of the chain hole sheet stack in the longitudinal direction, that is, placing the member in the lateral direction, when it is used in the sheet discharge tray, the already stacked chain hole sheets can be bent in the longitudinal direction, so that the rigidity of the chain hole sheets in the lateral direction is enhanced, that is, in a gentle state in the lateral direction, the chain hole sheets are not easily rubbed to the 2 side when they slide; when it is used in a sheet-taking tray, it is possible to bend the already stacked chain hole sheets longitudinally, that is, to make the longitudinal direction softer, and the sheets are easily taken out in a small space.
