Detailed Description
Referring to fig. 1 to 3, an embodiment of the present invention provides a printer capable of reversely bending a paper, including a base 200, an upper cover 300, a first bending portion 421, a second bending portion 520, a third bending portion 530, and a fourth bending portion 540. The base 200 is provided with a lower paper bin 510, the upper cover 300 is provided with an upper paper bin 410, the upper cover 300 is connected with the base 200 in a turnover mode, when the upper cover 300 is closed on the base 200 in a turnover mode, the upper paper bin 410 and the lower paper bin 510 form a paper bin of the printer, and the paper bin is used for placing a rolled printing paper roll 600. The paper discharging channel 120 and the paper discharging port 130 are formed between the upper cover 300 and the base 200, and the paper bin, the paper discharging channel 120 and the paper discharging port 130 are sequentially communicated, so that when in use, printing paper is discharged from the paper bin along the paper discharging channel 120, passes through the thermal sensitive sheet and the rubber roller 110, and is discharged out of the printer from the paper discharging port 130.
As shown in fig. 2 and fig. 3, the first kink portion 421, the second kink portion 520, the third kink portion 530, and the fourth kink portion 540 are distributed in the paper discharging direction. The first bending portion 421 is connected in the upper cover 300, and when the upper cover 300 is connected to the base 200 in an inverted manner, the first bending portion 421 extends downward into the lower paper bin 510 and can be pressed against the upper surface of the paper 610. The second bending portion 520 is connected to the inside of the base 200 and located at the upper edge of the lower paper bin 510 for pressing the lower surface of the paper 610 upward. The third bending part 530 is connected in the base 200, and is located on a side of the rubber roller 110 of the printer away from the paper outlet 130, and is used for upward pressing the lower surface of the paper 610. The fourth bending part 540 is connected in the base 200 and located at the paper exit 130, and is used for pressing the lower surface of the paper 610 upward. It should be noted that the expression of the upper surface and the lower surface of the paper 610 in the present invention is based on a currently-used printer, in which the paper roll 600 of the currently-used printer rotates in a counterclockwise direction to discharge paper, and the upper surface of the paper 610 is also the outer surface of the paper 610 wound in a roll, that is, the printing surface of the paper 610. That is, if the paper roll 600 is rotated clockwise to discharge paper, and the positions of the first bending portion 421, the second bending portion 520, the third bending portion 530 and the fourth bending portion 540 are adjusted and replaced, which is consistent with the technical solution provided by the present invention, and all of which are within the protection scope of the present invention. In fig. 2 and 3, in order to facilitate discrimination between paper output path 120 and paper 610, paper 610 in paper output path 120 is indicated by a dotted line.
When the printer is used, firstly, when the printing paper comes out from the paper bin, the printing paper is pressed downwards by the first bending part 421, and the first bending part 421 extends downwards into the lower paper bin half 510, so that the paper 610 can be reversely bent to a greater extent in the opposite direction of the initial curling state, so that the paper 610 is curled in the opposite direction of the initial curling state. When the paper 610 passes through the second bending portion 520, the second bending portion 520 presses the lower surface of the paper 610 upward, so that the paper 610 that is over-corrected by the first bending portion 421 can be bent in the direction of the initial curling state to alleviate the over-correction of the paper 610. Before the paper 610 passes through the rubber roll 110 to realize printing, the paper 610 passes through the third bending part 530, at this time, the third bending part 530 can bend the paper 610 again according to the direction of the initial curling state, so as to relieve the over-correction of the paper 610 again, adjust the flatness of the paper 610, enable the paper 610 to pass through the rubber roll 110 more smoothly, and reduce the possibility of paper jamming of the paper 610. Finally, when the printed paper 610 is output from the paper outlet 130, the printed paper 610 will pass through the fourth bending part 540, the fourth bending part 540 can relieve the over-correction of the paper 610 again, so that the paper 610 is smoother, the paper outlet direction of the paper 610 can be upward, the experience of a user is better, after the paper 610 is torn down by the user, the corrected paper 610 is not curled any more, the user can directly check the printed content, the paper 610 does not need to be smoothed out with hands, and the use is more convenient.
Further, as shown in fig. 1 and 4, an upper inner lid 400 is connected to the inside of the upper lid 300, the upper half paper compartment 410 is opened in the upper inner lid 400, the upper inner lid 400 is connected to the paper pressing plate 420, the first bending part 421 is connected to the paper pressing plate 420, and the first bending part 421 extends in a direction away from the paper pressing plate 420. As shown in fig. 3 and 4, the width of the first bending portion 421 gradually decreases along the direction away from the paper pressing plate 420, and the portion of the first bending portion 421 pressed against the paper 610 is arc-shaped. When the folding paper feeding device is used, the upper cover 300 is turned over to cover the base 200, the paper 610 is discharged from the paper bin, the first bending portion 421 downwardly presses the paper 610, and the paper 610 is fed along two side walls of the first bending portion 421. Because the first bending portion 421 needs to bend the paper 610 reversely and needs to generate an over-correction effect to ensure that the initial bending state of the paper 610 is offset, the first bending portion 421 needs to apply a large acting force to the paper 610 to generate a large degree of reverse bending of the paper 610, and a portion of the first bending portion 421 abutting against the paper 610 is cambered, so that the paper 610 can be effectively prevented from being broken, cut or folded, and smooth paper feeding can be facilitated.
Further, with reference to fig. 3, when the upper cover 300 is turned over to cover the base 200, the distance from the first bending portion 421 to the lower half paper bin 510 is greater than one third of the depth of the lower half paper bin 510. Since the paper 610 is stored in a roll for a long time, if the degree of reverse bending is small, the reverse bending may not be complete and the effect is poor. Therefore, the distance setting in this embodiment can make the paper 610 to be subjected to a larger reverse bending action, so that the paper 610 is subjected to an over correction, and the over correction is short-term, so that after the paper 610 passes through the second bending part 520, the third bending part 530 and the fourth bending part 540, the over correction of the paper 610 can be quickly relieved, and the flatness of the paper 610 can be timely adjusted.
Further, referring to fig. 5, a lower inner cover 500 is connected to the base 200, the lower paper bin 510 is disposed on the lower inner cover 500, referring to fig. 3, a side wall of the paper discharging side of the lower paper bin 510 is an inclined surface inclined upward toward the paper discharging direction, and when the upper cover 300 is connected to the base 200 in an inverted manner, a gap between a side wall of the first bending portion 421 near the paper discharging opening 130 and a side wall of the lower paper bin 510 on the paper discharging side forms a part of the paper discharging passage 120. As shown in fig. 3, the second bending portion 520 is in transition connection with the side wall of the lower paper bin 510 at the paper outlet side, the second bending portion 520 is located at the upper edge of the lower paper bin 510 and extends upwards to form a protrusion, and the portion of the second bending portion 520 pressed against the paper 610 is arc-shaped, so that when the paper 610 is output from the paper bin, after passing through the first bending portion 421, the paper is fed along the paper outlet channel 120, and when passing through the second bending portion 520, the paper is lifted upwards by the second bending portion 520, thereby alleviating the over-correction of the paper 610. Specifically, the extension length of the second bending portion 520 is far less than the extension length of the first bending portion 421, and the extension length of the second bending portion 520 is between one eighth and one tenth of the extension length of the first bending portion 421, so that the over-correction of the paper 610 can be slightly alleviated, so as to prevent the paper 610 from being bent in two different directions to a greater extent in a short time, and the paper 610 is damaged. The second bending part 520, the third bending part 530 and the fourth bending part 540 gradually relieve the over-correction of the paper 610 in sequence, so that the paper 610 can be gradually flattened.
Further, referring to fig. 3, 5 and 6, the lower inner cover 500 has a first inclined surface 550 inclined downward along the paper discharging direction, the first inclined surface 550 is located between the second bending portion 520 and the third bending portion 530, the second bending portion 520 is in transition connection with the first inclined surface 550, one side of the third bending portion 530 close to the paper bin is in transition connection with the first inclined surface 550, one side of the third bending portion 530 close to the paper discharging opening 130 protrudes out of the first inclined surface 550, the height of the third bending portion 530 protruding out of the first inclined surface 550 is gradually increased along the paper discharging direction, and the height of the third bending portion 530 is lower than the height of the second bending portion 520. After the paper 610 is corrected by the second bending portion 520, the transition is performed at the first inclined portion 550, and then the third bending portion 530 is corrected, so that the transition buffer can be obtained at the first inclined portion 550, and the height of the third bending portion 530 is lower than the height of the second bending portion 520, which is smaller than the adjustment force of the second bending portion 520, and is more beneficial to the adjustment of the flatness of the paper 610. Specifically, the heights of the third bending part 530 and the fourth bending part 540 are both lower than the height of the rubber roller 110 of the printer. Therefore, when the paper 610 is fed in the paper discharging channel 120, the paper passes through the first bending portion 421, the second bending portion 520, the paper discharging channel 120 between the first inclined surface 550 and the second inclined surface 430, the third bending portion 530, the rubber roller 110 and the fourth bending portion 540 in sequence, the adjustment directions of the paper 610 by the first bending portion 421, the paper discharging channel 120 between the first inclined surface 550 and the second inclined surface 430 are the same, the adjustment directions of the paper 610 by the second bending portion 520, the third bending portion 530, the rubber roller 110 and the fourth bending portion 540 are the same and opposite to the adjustment direction of the first bending portion 421, the flatness of the paper 610 can be gradually adjusted through multiple times of interval adjustment with different directions, and the paper 610 can be effectively prevented from being damaged.

Specifically, the first inclined plane 550 is an arc-shaped inclined plane recessed downward, the second inclined plane 430 is an arc-shaped inclined plane protruding downward, and after the paper 610 is adjusted by the second bending part 520, the paper 610 can be better buffered by shaping with a longer distance between the first inclined plane 550 and the second inclined plane 430, so that the paper 610 is further more flat. Specifically, as shown in fig. 1, 5 and 6, the third bending portion 530 is a multi-segment protrusion disposed in parallel along the length direction of the lower inner cover 500, the fourth bending portion 540 is an arc-shaped inclined surface located at the paper outlet 130 and recessed inwards, and the fourth bending portion 540 is inclined upwards towards the paper outlet direction, so that the paper 610 is output upwards when being output from the paper outlet 130, and the experience of the user is improved.
