Referring to the figure, this embodiment provides a control structure for the paper feed roller, including: a paper feed support 1, a paper feed gear support 2, a carbon belt gear support 3, a paper feed roller 4, a first limiter 7 and a second Limiting piece 8;

The paper feed gear bracket 2 is provided with a paper feed gear 21 and a paper output gear 22; the paper feed bracket 1 is moved between the non-working position and the working position by the first power source; the carbon belt gear bracket 3 The first power source acts on the hand, so that the carbon belt gear bracket 3 is connected or separated from the carbon belt shaft;

When the paper feed support 1 is in the working position, and the carbon belt gear support 3 is separated from the carbon ribbon shaft, the paper feed support 1 is separated from the second limiter 8; the paper feed gear support 2 is in the second Under the action of the power source, it swings to the interlocking position where the paper feed gear 21 or the paper output gear 22 meshes with the paper feed roller 4;

When the paper feed support 1 moves from the working position to the non-working position, the paper feed support 1 presses against the second stopper 8, and makes the second stopper 8 drive the paper feed gear support 2 to swing To the idling position where the paper feed gear 21 and the paper feed roller 4 are separated;

The paper feed support 1 moves from the working position to the non-working position, and when the carbon belt gear support 3 is connected to the carbon ribbon shaft, the paper feed support 1 presses the second stopper 8, and the carbon belt gear support 3 3. Press the first limiting member 7, and make the first limiting member 7 cooperate with the paper feeding gear bracket 2 along the swinging direction, so as to limit the paper feeding gear bracket 2 in the forward position. The idling position where the paper gear 21 and the paper feed roller 4 are separated.

In this embodiment, the working position refers to the position where the paper feeding support 1 is in an inclined state, and the non-working position refers to the position where the paper feeding support 1 is in a horizontal state.

Specifically, the first power source includes a first motor, a first head gear, a second head gear and a third head gear 5; the side of the third head gear 5 is provided with a The first guide groove 51 of the bracket 1 is used to control the second guide groove 52 of the carbon belt gear bracket 3; the first head gear and the second head gear are connected between the third head gear 5 and the first motor During this period, the output shaft of the first motor drives the third head gear 5 to rotate through the first head gear and the second head gear. The third head gear 5 can drive the paper feed support 1 to lift or descend during the rotation process, and can also drive the carbon belt gear support 3 to translate left and right.

The first motor controls the clockwise or counterclockwise rotation of the third head gear 5 through forward rotation and reverse rotation. Move to the working position, and the third head gear 5 drives the carbon belt gear bracket 3 to translate to a position separated from the first limiting member 7 . When the third head gear 5 rotates clockwise, the paper feed support 1 moves from the working position to the non-working position, and the third head gear 5 drives the carbon belt gear bracket 3 to move in translation with the first stopper. 7 top pressure position. When the third head gear 5 continues to rotate clockwise, the paper feed support 1 remains in the non-working position, and the three-head gear drives the carbon belt gear bracket 3 to translate to a position separated from the first limiter 7 .

In this embodiment, in order to realize the rewinding of the carbon belt gear, the carbon belt gear bracket 3 is provided with a first carbon belt gear 31, and the carbon belt gear bracket 3 is translated to the position where it is pressed against the first limiter 7 position, the first ribbon gear 31 meshes with the second ribbon gear 32, and the second ribbon gear 32 is arranged on the ribbon shaft. Therefore, when the first ribbon gear 31 meshes with the second ribbon gear 32, the ribbon rewinding group 9 can start to work.

The second power source includes a second motor and a linkage gear 6 linked with the second motor; the linkage gear 6 meshes with the first ribbon gear 31 . In this way, the first carbon belt gear 31 can be driven to rotate by the second motor, thereby realizing the work of the entire carbon belt rewinding group 9 .

In addition, when the first limiting member 7 and the second limiting member 8 are in a free state, the paper feeding gear bracket 2 needs to be rotated clockwise or counterclockwise, so that the paper feeding gear 21 or the paper output gear 22 and the feeding gear Paper roll 4 engages. Only in this way can the paper feed and paper output actions be realized, so the linkage gear 6 is also coordinated with the paper feed gear bracket 2 to drive the paper feed gear bracket 2 to rotate clockwise or counterclockwise, and the paper feed gear The bracket 2 swings to the interlocking position where the paper feed gear 21 or the paper discharge gear 22 meshes with the paper feed roller 4 .

In addition, a pair of toothed steel shafts are connected to the shaft center of the linkage gear 6 . After the paper feeding roller 4 sends the printing sheet into the machine, the printing sheet is clamped by the toothed steel shaft, and the precise position movement is carried out for subsequent printing work.

The control method of the above-mentioned paper feeding roller 4 can be divided into the following steps:

1. When feeding paper:

1) The first motor controls the third head gear 5 to rotate counterclockwise: the paper feed support 1 is lifted, and the paper contacts the paper feed roller 4; the carbon belt gear support 3 is restricted by the second guide groove 52 . At this time, the paper feed bracket 1 and the carbon belt gear bracket 3 are separated from the first limiter 7 and the second limiter 8 respectively, and the first limiter 7 and the second limiter 8 are all in a free state, and the paper feed gear Support 2 can rotate freely.

2) The second motor controls the linkage gear 6 to rotate counterclockwise. At this time, the linkage gear 6 drives the paper feed gear bracket 2 to rotate counterclockwise, so that the paper feed gear 21 drives the paper feed roller 4 to rotate, so that the paper feed roller 4 turns the paper below it. into the print area.

2. When the toothed steel shaft clamps the printing sheet:

1) The first motor controls the third head gear 5 to rotate counterclockwise: the paper feed support 1 is placed horizontally, and the paper feed support 1 presses the second limiter 8 at the same time; the carbon belt gear support 3 is held by the second guide groove 52 limits live. At this time, the first limiting member 7 is in a free state, and one end of the second limiting member 8 is in a state of being pressed down by the paper feeding support 1 . The other end of the second limiter 8 presses against the paper feed gear bracket 2, and drives the paper feed gear bracket 2 to swing along the pressing direction, and the paper feed gear 21 is separated from the paper feed roller 4, that is, the paper feed gear bracket 2 Swivel to idle position. At this time, the paper feeding roller 4 cannot rotate, so that the remaining printing sheets on the paper feeding support 1 will not be brought into the machine.

2) The second motor controls the linkage gear 6 to rotate counterclockwise to send the printing sheet to the leftmost printing start position. Since the second limiting member 8 and the paper feeding gear bracket 2 are limited in the counterclockwise direction, the paper feeding gear bracket 2 will not be driven to rotate when the linkage gear 6 rotates counterclockwise.

3. When printing Y color:

1) The first motor controls the third head gear 5 to rotate clockwise, so that the paper feed support 1 remains in a horizontal state, and the carbon belt gear support 3 is translated to the rightmost side, so that the first carbon belt gear 31 and the second carbon belt Gear 32 meshes. At this time, both the first limiting member 7 and the second limiting member 8 are in the working state, and the paper feeding gear bracket 2 is fixed at the idling position by the two limiting members.

2) The second motor controls the linkage gear 6 to rotate clockwise, so that the paper moves toward the paper bin, and is recorded and printed. Ribbon rewinding group 9 also works clockwise. Since the paper feeding gear bracket 2 cannot rotate clockwise or counterclockwise at this time, when the second motor controls the interlocking gear 6 to rotate clockwise, the paper feeding gear bracket 2 cannot rotate either. It is ensured that the paper feeding roller 4 will not rotate during the printing process, and the situation of paper feeding by mistake will not occur.

4. When printing Y color and returning the paper:

1) The first motor controls the head gear to maintain the position of step 3.

2) The second motor controls the linkage gear 6 to rotate counterclockwise, so that the printed sheet moves to the left and retreats.

5. Print M color-return paper-print C color-return paper-laminate: Repeat step 2 and step 3.

6. Paper output:

When the lamination printing is completed, half of the printed sheet remains inside the device, and the paper needs to be completely sent to the outside of the paper feed roller 4 .

1) The first motor controls the third head gear 5 to rotate clockwise. At this time, the paper feeding support 1 remains horizontal, and the carbon belt gear support 3 is restricted by the second guide groove 52 . At this time, the second limiting member 8 is in the working state, and the first limiting member 7 is in the free state. At this time, the paper feeding gear bracket 2 can only rotate clockwise and cannot rotate counterclockwise.

2) The second motor controls the linkage gear 6 to rotate clockwise. At this time, the paper feed gear bracket 2 also rotates clockwise, so that the paper output gear 22 meshes with the paper feed roller 4, and the paper feed roller 4 rotates clockwise to drive the printing film. The material moves toward the paper bin.

This embodiment also provides a printing device equipped with the control structure for the paper feeding roller 4 as described above.

The above is only a preferred embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any person familiar with the technical field can use this concept to carry out the present invention within the technical scope disclosed in the present invention. Non-substantial changes all belong to the act of violating the protection scope of the present invention.
