For example, ordinary paper (70gsm) can hold about 100 sheets, while thick card paper can only hold about 30 sheets. In general office application environments, it is nothing more than frequent addition of paper, but if it is applied to the self-service field, frequent addition of paper is obviously unrealistic. Therefore, an external card paper conveyor is required. Summary of the invention

[0028] In order to make the content of the present utility model easier to be clearly understood, the present utility model will be further described in detail below according to specific embodiments and in conjunction with the accompanying drawings.

[0029] As Figures 1 to 4 shown, a card paper conveying device includes a paper pre-separation component, and the paper pre-separation component includes:

[0030] A card paper extraction component, which is adapted to receive the card paper 10 and convey the card paper 10 in the first direction;

[0031] A pre-separation plate 2, the pre-separation plate 2 includes an inclined wall 21, the inclined wall 21 includes a separation upper end 21a and a separation lower end 21b, the inclined wall 21 is inclined along the first direction from the separation upper end 21a to the separation lower end 21b, and the height of the separation lower end 21b of the inclined wall 21 ≤ the height of the uppermost part of the card paper extraction component. A part of the side of the inclined wall 21 close to the card paper extraction component forms a pre-separation channel 21c; wherein,

[0032] When the card paper 10 extracted by the card paper extraction component is conveyed in the first direction, it is blocked by the pre-separation plate 2, and the lowermost card paper 10 is adapted to enter the pre-separation channel 21c under the action of the card paper extraction component and the inclined wall 21.

[0033] Of course, the card paper extraction component can be an extraction roller set, and the extraction roller set includes two extraction rollers 1 adapted to be driven to rotate; the card paper extraction component can also be a conveyer belt that can be driven to act; the height of the uppermost part of the card paper extraction component refers to the height of the outer edge of the extraction roller 1 or the upper layer of the conveyer belt, ensuring that when the card paper is extracted, the lowermost card paper can be blocked by the inclined wall 21.

[0034] In this embodiment, the number of the extraction rollers 1 is not limited to two and can be specifically set according to needs.

[0035] Such as Figure 2 As shown, in this embodiment, the pre-separation plate 2 can further include a vertical wall 22, and the vertical wall 22 is adapted to block the card paper 10, and the vertical wall 22 is used to regulate and block the card paper 10.

[0036] In this embodiment, in order to increase the friction force of the inclined wall 21, a separation friction sheet can be provided on the side of the inclined wall 21 close to the card paper extraction component.

[0037] In this embodiment, such as Figure 2 As shown, the card paper conveying device can further include a paper separation component, and the paper separation component includes a separation roller 31 adapted to be driven to rotate and a separation member 23 located above the separation roller 31 and cooperating with the separation roller 31 to form a separation channel 20 for separating the card paper 10 after passing through the pre-separation channel 21c.

[0038] In this embodiment, such as Figure 3 As shown, a separation wheel 31a is provided on the separation roller 31, and friction protrusions 23a protruding towards the separation roller 31 are provided on the separation member 23 between adjacent separation wheels 31a, and the card paper 10 passing through the separation channel 20 forms a wavy structure under the action of the separation wheel 31a and the friction protrusions 23a.

[0039] Specifically, such as Figure 2 、 3 As shown, the separation member 23 can be arranged on the pre-separation plate 2 and connected to the lower end 21b of the separation.

[0040] Specifically, the card paper conveying device further includes a paper conveying component, and the paper conveying component includes two conveying rollers 41 that form a conveying channel therebetween and are adapted to be driven to rotate, and the separated card paper 10 enters the conveying channel.

[0041] Specifically, such asFigure 2 As shown, the card paper conveying device may further include a ramp channel 5 that slopes upward in the first direction, and the paper conveying assembly is adapted to convey the paper in the conveying channel onto the ramp channel 5.

[0042] Specifically, as Figure 2 shown, the card paper conveying device may further include a controller. A paper shortage sensor 6 adapted to detect whether there is card paper 10 on the ramp channel 5 is provided below the ramp channel 5. The paper shortage sensor 6 is connected to the controller, and the controller is adapted to control the card paper conveying device to perform card paper conveying actions according to the control signal of the paper shortage sensor 6.

[0043] The actions of extraction and separation in this embodiment are as follows:

[0044] S1. The extraction roller 1 rotates counterclockwise, driving the lowermost card paper 10 to move leftward. At this time, the card paper 10 above this card paper 10 is bound to move leftward accordingly, and all the moved card papers 10 will abut against the inclined wall 21.

[0045] S2. The front end of the card paper 10 abuts against the inclined wall 21, and the resistance causes the moving card paper 10 to be blocked.

[0046] S3. The extraction roller 1 continues to rotate counterclockwise. The lowermost card paper 10 generates a slip as its front end abuts against the inclined wall 21 due to a relatively large driving force. While slipping, the front end of the card paper 10 moves downward along the inclined wall 21.

[0047] S4. Due to the relatively large rigidity of the card paper 10 itself, when the head of the card paper 10 dips downward, the stronger the reaction force that the head of the card paper 10 lifts upward, which is equivalent to the inclined wall 21 pushing the paper head backward. At this time, if there are multiple card papers following the lowermost one out, the upper ones will surely be subject to great resistance while the driving force is insufficient (this driving force comes from the friction between the lower card paper 10 and the upper card paper 10). As a result, the upper card papers 10 are blocked, and the lowermost card paper 10 can be driven forward, as Figure 4 shown;

[0048] S5. The card paper 10 continues to move to the separating member 23. At this time, the lower part of the card paper will come into contact with the separating roller 31, while the upper part is the fixed friction protrusion 23a, and the card paper 10 is deformed into a wavy shape. If more than one piece of paper enters at this time, for example, 2 pieces, then the upper part is completely resistance, while the lower part is the driving force. Under the action of the rigidity of the card paper 10 itself, the lower card paper 10 is pressed onto the separating roller 31, and the upper card paper 10 is blocked by the upper friction protrusion 23a, thereby only allowing the lower one to pass through. This step is for insurance to ensure the reliability of the separation of the card paper 10.

[0049] S6. When the card paper 10 enters the conveying roller 41 and is clamped by the conveying roller 41, the sensor detects it, and the driving of the extraction roller 1 and the separation roller 31 stops. At this time, the card paper 10 will be pulled out by the conveying roller 41, conveyed until the end of the paper leaves the sensor, and then the conveying motor driving the conveying roller 41 stops after a delay.

[0050] S7. The outside of the conveying roller 41 is a slope, that is, a slope channel. After the card paper 10 reaches the slope, it climbs up until the end of the card paper 10 breaks away from the conveying roller 41. Then the card paper 10 will break away from the restraint and fall by its own gravity, and enter the manual feed tray of the printer to complete the paper loading work. The advantages of this method are as follows: ① The module is directly placed on the printer, maximizing the use of the existing space, and the whole machine is small and convenient for layout; ② There is no need for the connection between the rubber rollers, and the docking application is simpler; ③ The situation of the card paper 10 tilting can be avoided. Since the movement process of the card paper 10 is completely completed under the regulation of the side baffles, there is no need to worry about the paper tilting problem caused by docking.

[0051] S8. When the paper shortage sensor 6 detects the disappearance of the paper, the card paper conveying device executes the next paper feeding task to keep the manual feed tray always in a state with paper, without requiring the module to feed paper again.

[0052] The specific embodiments described above further elaborate on the technical problems solved, technical solutions and beneficial effects of the present invention. It should be understood that the above are only specific embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
