Example one

Referring to fig. 1 to 7, the present embodiment provides a printing structure, which includes a housing 11 and a printing assembly 12.

The housing 11 includes an upper shell 111 and a lower shell 112 which are connected in a snap-fit manner, and the upper shell 111 and the lower shell 112 are snap-fit to form a paper feeding passage 113 for moving paper.

The printing assembly 12 includes a printing rubber roller 121, a printing head 122, a drawing member 123 connected to the printing head 122 and driving the printing head 122 to approach or depart from the printing rubber roller 121, a left flap 124 and a right flap 125 connected to the drawing member 123 and disposed on the left and right, a left sensor 126 for sensing the position of the left flap 124 and a right sensor 127 for sensing the position of the right flap 125, the printing rubber roller 121 is rotatably connected to the lower shell 112, the printing head 122 and the printing rubber roller 121 are disposed on opposite sides of the paper feeding passage 113, the printing head 122 is fixed at one end of the drawing member 123 facing the paper feeding passage 113, the left flap 124 and the right flap 125 are both fixed at one end of the drawing member 123 departing from the paper feeding passage 113, the drawing member 123 moves toward the printing rubber roller 121 to make the left flap 124 depart from the left sensor 126 and then the right flap 125 departs from the right sensor 127, and when the right flap, the print head 122 prints on the paper between the print roller 121 and the print head 122, and after the print head 122 finishes printing, the pulling member 123 moves in a direction away from the print roller 121, so that the right flap 125 passes through the right sensor 127, and then the left flap 124 reaches the left sensor 126.

The left sensor 126 and the right sensor 127 are both groove-type photoelectric sensors, each including a transmitter and a receiver, which are installed face to face on both sides of a groove to form a groove-type photoelectric sensor. The emitter can emit infrared light or visible light, and the receiver can receive light without resistance. However, when the detected object passes through the groove, the infrared light or the visible light is blocked, the photoelectric switch acts and outputs a switch control signal, and therefore the position information of the detected object entering the groove is obtained. For the left sensor 126, the detected object is the left flap 124, and for the right sensor 127, the detected object is the right flap 125.

To achieve the effect of the left and right blocking

pieces

124 and 125 acting on the left and

right sensors

126 and 127, respectively (blocking infrared light or visible light from reaching the receiver when entering the slot), three ways can be used:

the first mode is as follows: the left blocking piece 124 and the right blocking piece 125 have a height difference, the left sensor 126 and the right sensor 127 are located at the same height position, and the left blocking piece 124 and the right blocking piece 125 act on the left sensor 126 and the right sensor 127 in sequence along with the approach of the traction piece 123.

The second mode is as follows: the left blocking piece 124 and the right blocking piece 125 have the same height, the left sensor 126 and the right sensor 127 have a height difference, and the left blocking piece 124 and the right blocking piece 125 act on the left sensor 126 and the right sensor 127 in sequence along with the approach of the traction piece 123.

The third mode is as follows: the left blocking piece 124 and the right blocking piece 125 have a height difference, the left sensor 126 and the right sensor 127 have a height difference, and the two height differences are different, so that the left blocking piece 124 and the right blocking piece 125 act on the left sensor 126 and the right sensor 127 in sequence.

The illustrated embodiment takes a third approach. The left flap 124 is 3.5mm higher than the right flap 125, and the sensing position of the left sensor 126 (the position of the passage of the infrared light emitted by the emitter to the receiver) is 4.0mm higher than the right sensor 127. In the process that the elliptical wheel 128 rotates from the long side to the short side to be abutted to the drawing piece 123, the drawing piece 123 moves towards the printing rubber roller 121, so that the left blocking piece 124 leaves the left sensor 126, the right blocking piece 125 leaves the right sensor 127, and when the right blocking piece 125 leaves the right sensor 127, the printing head 122 is abutted to the printing rubber roller 121. The elliptical wheel 128 rotates from the short side to the long side to be abutted to the drawing piece 123, and the drawing piece 123 moves in the direction away from the printing rubber roller 121, so that the right blocking piece 125 passes through the right sensor 127, and then the left blocking piece 124 reaches the left sensor 126. Under this design, through left sensor 126 and right sensor 127 can learn three positions of traction member 123, correspond three positions of print head 122: a position abutting against printing blanket 121, a position farthest from printing blanket 121, and a position therebetween. When the two blocking sheets both leave the two sensors, the printing head 122 abuts against the printing rubber roller 121, and when the two blocking sheets both block the two sensors, the printing head 122 is far away from the printing rubber roller 121.

It should be noted that, a flap can be used, and the change of the moving position of the flap can also be sensed by sequentially entering the left sensor 126 and the right sensor 127. However, in this solution, one blocking piece acts on two sensors in sequence, which is only suitable for the situation that the measured moving distance is at least larger than the external dimension of one sensor, but the moving distance to be measured in this solution is very small, therefore, two blocking pieces and two sensors are designed and a specific design of position is given to realize the sensing of small distance. Similarly, the movement of the blocking piece is measured by adopting a sensor, and only the entering and leaving positions of the blocking piece can be measured, so that the position size which can be measured is limited by the size distance between the upper end and the lower end of the blocking piece, and the method is not suitable for sensing small distance.

In summary, the printing structure provided in this embodiment moves the detection position to the left and right blocking

sheets

124 and 125 by the arrangement of the pulling member 123, thereby solving the spatial arrangement problem directly arranged on the print head 122. The left and

right baffles

124 and 125, the left and

right sensors

126 and 127 are designed in a matching manner, which is beneficial to more accurately judging the position state of the printing head 122, so that when the printing structure is in a printing state, the printing head 122 is in a position abutting against the printing rubber roller 121, and after printing is completed, the printing head 122 can be far away from the printing rubber roller 121, so that interference caused by movement of lottery tickets in the paper feeding channel 113 is avoided.

Referring to fig. 6 or fig. 7, the pulling member 123 is rotatably connected to the upper housing 111, and the distance between the rotating shafts of the left and

right stoppers

124 and 125 and the pulling member 123 is greater than the distance between the rotating shafts of the print head 122 and the pulling member 123. The arrangement properly enlarges the moving position of the printing head 122 close to or far from the rubber roller into a larger sensing distance by the lever principle, thereby improving the control precision of the displacement of the printing head 122 which can be sensed.

Referring to fig. 3 and 6, the printing assembly 12 further includes an elliptical wheel 128 and an elastic member 129, the elliptical wheel 128 is rotatably connected to the upper housing 111 and located on a side of the drawing member 123 facing the printing roller 121, the elliptical wheel 128 has long sides and short sides alternately arranged, the elliptical wheel 128 rotates to make the long sides or the short sides alternately abut against the drawing member 123, one end of the elastic member 129 is connected to the drawing member 123 and the other end is connected to the upper housing 111, and the elastic member 129 is used for applying a force to the drawing member 123 facing the printing roller 121. When the elliptical wheel 128 rotates from the long side to the short side to abut against the traction piece 123, the traction piece 123 moves towards the printing rubber roller 121 under the action of the elastic piece 129 to enable the printing head 122 to abut against the printing rubber roller 121, and when the elliptical wheel 128 rotates from the short side to the long side to abut against the traction piece 123, the traction piece 123 overcomes the elastic force of the elastic piece 129 to move in the direction away from the printing rubber roller 121 to enable the printing head 122 to be far away from the printing rubber roller 121.

The design of the elliptical wheel 128 is simple and advantageous in reducing the overall size of the device compared to a lead screw or other moving mechanism. The elastic member 129 is provided to improve the pressing degree of the print head 122 and the printing rubber roller 121, thereby improving the printing effect. Specifically, in the present embodiment, the elliptical wheel 128 is located between the paper feeding path 113 and the pulling member 123. In other embodiments, the elliptical wheel 128 is located on a side of the pulling member 123 facing away from the paper feed path 113. Accordingly, the elastic member 129 serves to apply a force to the pulling member 123 away from the printing blanket 121. This arrangement enables the drawing member 123 to move closer to and away from the printing blanket 121, but because the size of the elliptical wheel 128 is fixed, the maximum distance that the print head 122 moves toward the printing blanket 121 is a fixed value, and there is no elasticity. In this embodiment, the elliptical wheel 128 and the elastic member 129 are arranged in positions, so that when the print head 122 abuts against the print roller 121, the elastic force of the elastic force is adjusted, and the acting force applied to the print roller 121 is still applied to the print head 122, so that the print head 122 is more attached to the print roller 121. In addition, due to the elasticity of the elastic member 129, a buffer effect can be provided for the abutment or accidental collision of the print head 122 and the printing rubber roller 121, so that the print head 122 is protected to a certain extent.

The elliptical wheel 128 is driven by a print motor 130. When the mark printing is needed, the printing motor 130 drives the elliptical wheel 128 to rotate from the long side to the short side to be abutted against the traction piece 123, the printing head 122 clamps the lottery ticket together with the printing rubber roller 121 under the action of the elastic piece 129, the printing rubber roller 121 rotates, and the printing head 122 performs the printing operation. After printing is finished, the printing motor 130 drives the elliptical wheel 128 to rotate from the short side to the long side to abut against the drawing piece 123, so that the drawing piece 123 is forced to move in a direction away from the printing rubber roller 121, and the printing head 122 is separated from the printing rubber roller 121.

In this embodiment, the elastic member 129 is a spring structure.

Referring to fig. 6, the drawing member 123 includes a rotating part 1231, a printing part 1232, an extending part 1233, and a connecting part 1234, which are connected in sequence, the rotating part 1231 is rotatably connected to the upper shell 111, the printing part 1232 is connected to the print head 122, the extending part 1233 is connected to the printing part 1232 and extends in a direction away from the printing rubber roller 121, the connecting part 1234 is connected to the extending part 1233 and extends in a direction away from the rotating shaft of the drawing member 123, the connecting part 1234 is connected to the left flap 124 and the right flap 125 away from the surface of the printing rubber roller 121, and abuts against the elliptical wheel 128 toward the surface of the printing rubber roller 121.

In the illustrated embodiment, the overall drawing member 123 is approximately "Z" shaped, and the design that the extension 1233 extends away from the printing roller 121 and the design that the connecting portion 1234 extends away from the rotating shaft of the drawing member 123 make the extension 1233 and the connecting portion 1234 form a folded accommodating space, and the elliptical wheel 128 is located in the accommodating space. In combination with the design of the paper path 113, the print head 122 is located on one side of the paper path 113, and the elliptical wheel 128 is located between the paper path 113 and the pulling member 123, and if the pulling is a straight plate, the paper path 113 bends in the area between the print head 122 and the elliptical wheel 128. The paper path 113 can be made straight between the print head 122 and the elliptical wheel 128 by adjusting the size of the extension 1233 to facilitate the movement of the paper within the paper path 113.

In order to reduce the weight of the equipment, plastic materials are mostly adopted to replace metal materials. However, static electricity is easily generated by friction between the paper and the conveying roller 14, and is led out by the design of the metal buckle 16 and the metal side plate 15. Thus reducing the electrostatic interference to sensitive parts of the device.
