[0027] Figure 1 , Figure 2 , Figure 3 and Figure 5 The present invention provides a schematic diagram of a paper tearing device based on a folding paper printer. Figure 1 As shown, the paper tearing device 10 may include: a base 11 and an upper cover 12. The base 11 and the upper cover 12 are described in detail below.

[0028] The base 11 may include a first inclined wall 111 and a first curved wall 112 connected to one end of the first inclined wall 111. The inclined surface of the first inclined wall 111 conforms to the rule of paper moving in, and the curved surface shape of the first curved wall 112 conforms to the rule of paper moving out. A through hole 1111 is provided on the first inclined wall 111, and a first sensor 13 for detecting paper tearing is provided at the through hole 1111. The first sensor 13 may be a reflection sensor, and the size of the first sensor 13 matches the size of the through hole 1111. The first sensor 13 is used to detect paper located on the first inclined wall 111. The base 11 may also include a first side wall 113 and a second side wall 114 disposed opposite to the first side wall 113. The first side wall 113 is connected to the first inclined wall 111 and the first curved wall 112, and the second side wall 114 is connected to the first inclined wall 111 and the first curved wall 112. The first inclined wall 111 , the first curved wall 112 , the first side wall 113 and the second side wall 114 form a first receiving space 1 .

[0029] The upper cover 12 may include a second inclined wall 121 and a second curved wall 122 connected to one end of the second inclined wall 121, and a paper tearing member 123 is provided in the extending direction of the second inclined wall 121. The second inclined wall 121 matches the first inclined wall 111, and the second curved wall 122 matches the first curved wall 112. When the upper cover 12 is buckled with the base 11, a paper tearing member 123 is formed. Figure 2 In this structure, the second inclined wall 121 and the first inclined wall 111, and the second curved wall 122 and the first curved wall 112 form Figure 5 and Figure 6 The transmission channel 1 shown contains a paper tearing member 123, and the distance between the paper tearing member 123 and the bottom surface of the transmission channel 1 is less than a first threshold. The first threshold can be set according to actual conditions, and illustratively, the first threshold is less than 1 mm.

[0030] Of course, in order to facilitate storage, the paper tearing device is made neater. Figure 3 As shown, the above-mentioned paper tearing device 10 may also include: a receiving structure 14 for receiving paper. The size of the receiving structure 14 matches the size of the paper. When the receiving structure 14 receives folded paper, the folded paper is input into the transmission channel 1 through the paper inlet of the transmission channel 1.

[0031] like Figure 4 As shown, the above-mentioned paper tearing device 10 may also include: a driving device 15 and a controller 16. The driving device 15 is arranged at the paper inlet of the transmission channel 1. The driving device 15 is used to drive the folded paper to move in the transmission channel 1. Exemplarily, when the driving device 15 rotates clockwise, the driving device 15 drives the paper to move from the paper inlet of the transmission channel 1 to the paper outlet of the transmission channel 1. When the driving device 15 rotates counterclockwise, the driving device 15 drives the paper to move from the paper outlet of the transmission channel 1 to the paper inlet of the transmission channel 1. The controller 16 is electrically connected to the driving device 15 and the first sensor 13, and the controller 16 is used to control the driving device 15 to drive the paper to enter or move out of the transmission channel according to the information collected by the first sensor 13. Exemplarily, when the first sensor 13 detects that there is no paper on the first inclined wall 111, the first sensor 13 sends the detection information to the controller 16, and the controller 16 generates a first instruction for instructing the driving device 15 to rotate clockwise according to the information, and sends the first instruction to the driving device 15. The driving device 15 rotates clockwise according to the first instruction to drive the paper to move from the paper inlet of the transmission channel 1 to the paper outlet of the transmission channel 1. After the paper of the second threshold value enters the transmission channel 1, the controller 16 instructs the driving device 15 to rotate counterclockwise. At this time, the tearing component 123 resists the tear marks of the two papers. Under the force of the driving device 15 driving the paper to move out of the transmission channel 1, the tear marks between the two papers are torn open. In this case, when the first sensor 13 detects that there is no paper on the first inclined wall 111, the controller 16 can determine that the paper tearing is completed based on this information, thereby realizing automatic paper tearing, improving paper tearing efficiency, and reducing labor costs.

[0032] In some embodiments, Figure 4As shown, the above-mentioned paper tearing device 10 may also include: a second sensor 17 electrically connected to the controller 16, the second sensor 17 is arranged at the paper inlet of the transmission channel 1, and is used to detect the number of papers entering the transmission channel 1. In actual application, when the second sensor 16 detects that the number of papers moved into the paper inlet reaches the second threshold, the second sensor 16 sends the information of the number of papers to the controller 16, and the controller 16 generates a second instruction for instructing the driving device 15 to rotate counterclockwise according to the information, and sends the second instruction to the driving device 15. The driving device 15 rotates counterclockwise according to the second instruction to drive the paper to move from the paper outlet of the transmission channel 1 to the paper inlet of the transmission channel 1. In this case, the paper tearing component 123 supports the folded paper, and under the force of the driving device 15 driving the paper to move out of the transmission channel 1, the folded paper is torn along the tear mark to achieve the purpose of automatic paper tearing, thereby improving the paper tearing efficiency and reducing the labor cost.

[0033] The second threshold is a value arbitrarily input by the user. A button for selecting the second threshold may be provided on the paper tearing device 10. Alternatively, the controller 16 may be instructed to tear the paper according to the second threshold by inputting the second threshold on the application interface. For example, when the user needs to tear between every two sheets of paper, the second threshold may be set to 2. When the user needs to tear between the third and fourth sheets of paper, the second threshold may be set to 4.

[0034] The following is a detailed description with a specific example. An icon is provided at a fixed position on each sheet of folded paper. The second sensor 16 determines the number of sheets by identifying the icon. Figure 6 As shown, taking the second threshold value of 2 as an example, the driving device 15 rotates clockwise to drive the paper to move into the transmission channel 1. When the second sensor 16 detects that the number of paper is 2, at this time, the tear mark between the first paper and the second paper is already at the paper tearing component 123. The controller 16 receives the information sent by the second sensor 16, and instructs the driving device 15 to rotate counterclockwise to drive the paper to move out of the transmission channel 1 from the paper inlet. At this time, the paper tearing component 123 supports the tear mark between the first paper or the first paper and the second paper. Under the force of the driving device 15 driving the paper to move out of the transmission channel 1, the first paper and the second paper are torn apart along the tear mark.

[0035] In practical applications, the driving device 15 may be a print head of a printer. The print head may be 58 mm or 80 mm. Of course, the print head may also be of other sizes, which are not listed here. Figure 6As shown, when one bill needs to be printed, the drive device 15 rotates clockwise to print one bill. After printing, the drive device 15 can continue to drive the second sheet of paper to move into the transmission channel 1, so that the tear mark between the first sheet of paper and the second sheet of paper is at the paper tearing component 123. At this time, the second sensor 16 collects that the number of sheets of paper is 2. The controller 16 receives the information sent by the second sensor 16 and instructs the drive device 15 to rotate counterclockwise to drive the paper to move out of the transmission channel 1 from the paper inlet, so as to perform the paper tearing operation in the above manner.

[0036] In some embodiments, the tearing member 123 presses against the paper to tear the paper, which depends on the structure of the tearing member 123. Figure 1 As shown, the tearing part 123 can adopt the following structure: the tearing part 123 includes a first sawtooth 1231, a second sawtooth 1232 and a third sawtooth 1233 arranged in sequence, the second sawtooth 1232 is higher than the first sawtooth 1231 and the third sawtooth 1233, and the first sawtooth 1231 and the third sawtooth 1233 are consistent. Among them, the shapes and sizes of the first sawtooth 1231, the second sawtooth 1232 and the third sawtooth 1233 need to be set according to actual conditions, and are not specifically limited here. When the driving device 15 drives the paper to move out of the transmission channel 1, the second sawtooth 1232 is inserted into the tearing opening of the tear mark between the two sheets of paper, and under the force of the driving device 15 driving the paper to move out of the transmission channel 1, the tear mark between the two sheets of paper is torn open. Further, in order to facilitate the tearing part 123 to tear paper more easily, the inclination angle of the tearing part 123 is less than 110 degrees.

[0037] The material of the paper tearing member 123 can be metal or plastic, which is not specifically limited in the present invention. Preferably, in order to enhance the integrity of the paper tearing device structure, the paper tearing member 123 and the second inclined wall 121 are injection molded as one piece.

[0038] Of course, in some embodiments, the tearing member 123 is connected to the second inclined wall 121 via a telescopic device, and the telescopic device is electrically connected to the controller. The telescopic device is used to drive the tearing member 123 to telescope in the extension direction of the second inclined wall 121. The implementation structure of the telescopic device can adopt an existing telescopic structure, which is not specifically limited here. When the telescopic device is in an extended state, the tearing member can press the paper of the transmission channel. Continuing with the above example, when the second sensor 16 collects that the number of sheets of paper is 2, the controller 16 receives the information sent by the second sensor 16, indicating that the telescopic device is in an extended state, and instructs the drive device 15 to rotate counterclockwise to drive the paper to move out of the transmission channel 1 from the paper inlet. At this time, the tearing member 123 presses the first sheet of paper, and under the force of the drive device 15 driving the paper to move out of the transmission channel 1, the first sheet of paper and the second sheet of paper are torn apart along the tear mark.

[0039] In some embodiments, Figure 4 As shown, the paper tearing device 10 provided by the utility model may also include: a third sensor 18 electrically connected to the controller 16, the third sensor 18 is arranged at the paper outlet of the transmission channel 1, and is used to detect the paper at the paper outlet of the transmission channel 1. The third sensor 18 sends the detection information to the controller 16, and the controller 16 can generate a prompt instruction based on the detection information to instruct the paper tearing device 10 to send a prompt signal. Exemplarily, the paper tearing device 10 may include a prompt light, and when the third sensor 18 detects that there is paper at the paper outlet of the transmission channel 1, the controller 16 can indicate the prompt light to display red according to the detection information. When the third sensor 18 detects whether there is paper at the paper outlet of the transmission channel 1, the controller 16 can indicate the prompt light to display green according to the detection information. The embodiment of the utility model can effectively prompt the user of the paper situation at the paper outlet of the paper tearing device 10 by setting the third sensor 18 to detect the paper at the paper outlet, so as to facilitate timely handling of the paper outlet of the paper tearing device 10 and prevent the paper outlet from being blocked.

[0040] The utility model embodiment also provides a printer, which includes the paper tearing device in the above embodiment. The paper tearing device forms a transmission channel through the second inclined wall of the base and the first inclined wall of the upper cover, and the second curved wall of the base and the first curved wall of the upper cover, and the transmission channel accommodates a paper tearing component. When the paper of the second threshold value enters the transmission channel under the action of the driving device, the controller instructs the driving device to drive in the reverse direction. At this time, the paper tearing component supports the tear marks of the two papers, and under the force of the driving device driving the paper to move out of the transmission channel, the tear mark between the two papers is torn open. In this case, when the first sensor detects that there is no paper on the first inclined wall, the controller can determine that the paper tearing is completed based on the information, thereby realizing automatic paper tearing, improving paper tearing efficiency, and reducing labor costs.

However, the present invention is not limited to these disclosed embodiments.
