Description

Technical Field

[0001] The present application relates to the technical field of printers, and in particular to a paper stop mechanism and a printer. Background Art

[0002] In order to improve the adaptability of the existing printers and adapt to printing papers of different specifications, an adjustable paper clamping component perpendicular to the axial direction of the paper roll is generally set in the paper bin to prevent the position of the paper roll in the paper bin from moving randomly. When the positioning accuracy of the paper clamping component is poor, the paper roll will still shift or even the paper will be twisted and deformed during printing.

[0003] The detection mechanism inside the printer is usually set on the bottom wall of the paper bin. When the detection mechanism detects that the remaining amount of printing paper is less than the preset value, it will remind the user to add printing paper. Such a detection mechanism is difficult to detect whether the paper clamping component fixes the paper roll in the preset position, and it is also difficult to ensure the accuracy of the paper roll positioning. Summary of the invention

[0004] In view of this, the present application provides a paper blocking mechanism and a printer, which can improve the positioning accuracy of printing papers of different specifications in the paper bin to reduce the situation where the paper roll shifts and causes paper jams.

[0005] One embodiment of the present application provides a paper blocking mechanism. The paper blocking mechanism includes a base, a baffle group and a sensor. The baffle group has a paper feeding channel. The baffle group includes two baffles. The two baffles are arranged on the base and can slide relative to each other along a first direction. A paper storage space for placing a paper roll is formed between the two baffles. The paper feeding channel and the paper storage space are connected to discharge the printing paper of the paper roll. The first direction is parallel to the axial direction of the paper roll. The sensor is arranged on at least one baffle and is used to detect the printing paper in the paper feeding channel.

[0006] When the paper baffle mechanism is working, the paper roll is placed between the two baffles, and the printed paper on the paper roll is discharged through the paper feed channel on the baffle group. When the sensor does not detect the printed paper, it may be that there is no printed paper in the paper storage space, or the two baffles do not hold the paper roll, that is, there is a large gap between the paper roll and the baffles; if the printed paper is indeed used up, the user replenishes the paper. If the two baffles do not hold the paper roll, adjust the baffle until the sensor detects that there is printed paper in the paper feed channel. When the sensor detects that there is printed paper, that is, there is paper in the paper storage space and the two baffles hold the paper roll. The paper baffle mechanism provided in the present application is provided with a sensor on at least one baffle, which can simultaneously identify whether there is printed paper in the paper feed channel and whether the two baffles hold the paper roll.

[0007] In some embodiments of the present application, the baffle includes a baffle body. A paper storage space is formed between the two baffle bodies. The baffle also includes a mounting portion. The mounting portion is connected to the baffle body of the baffle. A paper feed channel is located at the mounting portion. The mounting portion is provided with a detection channel connected to the paper feed channel. A sensor is provided at the mounting portion and senses the printing paper in the paper feed channel through the detection channel.

[0008] For the baffle with the sensor, the baffle includes a baffle body and a mounting portion. Compared with directly mounting the sensor on the baffle body, the mounting portion can provide a stable and appropriate mounting position for the sensor. Furthermore, the distribution direction of the mounting portion and the baffle body of the baffle where it is located is perpendicular to the first direction, that is, the mounting portion is located along the paper output direction of the printing paper and away from the paper roll body. In this way, the sensor can be effectively prevented from affecting the paper roll output, and at the same time, the sensor can detect whether there is printing paper in the paper feeding channel.

[0009] In some embodiments of the present application, the baffle further includes a paper guide portion, which is disposed on a side of the mounting portion close to the paper containing space, and gradually moves away from the base in a direction away from the paper feeding channel.

[0010] The paper guide helps the printing paper pass through the paper feed path more smoothly, which helps to ensure that the printing paper reaches the printing position accurately. The paper guide gradually moves away from the base in the direction away from the paper feed path, which helps to make paper of different thicknesses pass through the paper feed path and the paper guide to output the paper.

[0011] In some embodiments of the present application, the baffle is slidable relative to the base to drive the sensor to slide relative to the base.

[0012] The baffle plate provided with the sensor is slidably connected to the base, so that the sensor can slide along the first direction along with the baffle plate on which it is located, which is conducive to placing the sensor in the best detection position.

[0013] In some embodiments of the present application, the baffle further includes a toggle portion, which is disposed on a side of the baffle body of the baffle away from the base and close to the mounting portion of the baffle.

[0014] Since the sensor is arranged in the mounting part of the baffle, the center of gravity of the entire baffle will be close to the mounting part. When the baffle equipped with the sensor is slidably connected to the base, a toggle part is arranged on the side of the baffle body away from the base and close to the mounting part. This can provide a fulcrum for the user to toggle the baffle along the first direction, thereby facilitating the user to adjust the baffle.

[0015] In some embodiments of the present application, the base includes a base body and a connecting plate. The connecting plate is detachably connected to the base body. The connecting plate is provided with a guide groove. The mounting portion is slidably connected to the guide groove and is slidable relative to the guide groove along a first direction.

[0016] For the baffle plate provided with a sensor and slidable relative to the base, when installing, first slide the mounting portion into the guide groove along the first direction to assemble the baffle plate and the connecting plate; then assemble the connecting plate and the baffle plate as a whole with the base body. In this way, instead of assembling and disassembling the two baffle plates with the entire base, the connecting plate can be detachably connected to the base body, further simplifying the installation process. At the same time, the guide groove on the connecting plate makes the sliding of the baffle plate in the first direction more stable, reducing the shaking feeling when adjusting the baffle plate.

[0017] In some embodiments of the present application, the number of mounting parts is two. The two mounting parts are respectively a front mounting part and a rear mounting part. The front mounting part and the rear mounting part are arranged at intervals. The side of the front mounting part away from the paper storage space is connected to the side of the rear mounting part away from the paper storage space. The rear mounting part is slidably connected to the guide groove. The paper feed channel is located between the front mounting part and the rear mounting part. The sensor includes a signal sending part and a signal receiving part. The signal sending part is arranged at the front mounting part. The signal receiving part is arranged at the rear mounting part. The detection channel is connected between the front mounting part and the rear mounting part and intersects with the paper feed channel.

[0018] Thus, when the signal sent by the signal sending part is received by the signal receiving part, it means that there is no printing paper in the paper feeding path; otherwise, it means that there is paper in the paper feeding path. A part of the front mounting part is connected to the rear mounting part, and the rear mounting part is slidably connected to the guide groove. There is an assembly between the two mounting parts and the connecting plate to improve the connection strength between the baffle and the base.

[0019] In some embodiments of the present application, a baffle is provided with a sensor, the baffle is fixed to the base, and the other baffle is slidably connected to the base.

[0020] The baffle with the sensor is fixed relative to the base, and the other baffle does not need to be provided with a sensor but can slide relative to the base, and can also detect whether there is printing paper in the paper feeding channel and whether the two baffles clamp the paper roll.

[0021] In some embodiments of the present application, there are multiple sensors, and the multiple sensors are distributed along a direction perpendicular to the first direction.

[0022] On the baffle with sensors, there are multiple sensors and they are distributed in a direction perpendicular to the first direction; when multiple sensors are distributed in the paper output direction, that is, multiple sensors are arranged at intervals in the paper output direction, along the paper output direction, some sensors detect that there is no paper in the paper feed channel and another part of sensors detect that there is paper in the paper feed channel, indicating that a paper jam has occurred. When multiple sensors are distributed on both sides of the paper feed channel along the paper output direction, multi-point detection can be performed on the printing paper passing through the paper feed channel, further improving the detection accuracy.

[0023] In some embodiments of the present application, there are multiple sensors, and the multiple sensors are distributed along the first direction.

[0024] On the baffle with sensors, there are multiple sensors distributed along the first direction. When some sensors sense the presence of paper but other sensors cannot sense the printing paper, it can be confirmed that the baffle group does not clamp the paper roll. When all sensors cannot sense the printing paper, it can be confirmed that paper needs to be replenished.

[0025] In some embodiments of the present application, the base includes a base body and a connecting plate, which is detachably connected to the base body; a baffle groove is formed between the base body and the connecting plate, and both baffles are slidably connected to the baffle groove.

[0026] The two baffles are slidably connected to the base via a baffle sliding groove, making the structural coordination between the baffle group and the base simpler.

[0027] An embodiment of the present application provides a printer, which includes a paper stop mechanism.

[0028] In the above embodiment, the printer includes a paper stop mechanism, and a sensor is arranged on at least one baffle of the paper stop mechanism, which is conducive to ensuring that it can simultaneously identify whether there is printing paper in the paper feeding channel and whether the two baffles are jamming the paper roll, which helps to improve the printing quality.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0038] The embodiment of the present application provides a paper blocking mechanism. The paper blocking mechanism includes a base, a baffle group and a sensor. The baffle group has a paper feeding channel. The baffle group includes two baffles. The two baffles are arranged on the base and can slide relative to each other along a first direction. A paper storage space for placing a paper roll is formed between the two baffles. The paper feeding channel and the paper storage space are connected to discharge the printing paper of the paper roll. The first direction is parallel to the axial direction of the paper roll. The sensor is arranged on at least one baffle and is used to detect the printing paper in the paper feeding channel.

[0039] When the paper baffle mechanism is working, the paper roll is placed between the two baffles, and the printed paper on the paper roll is discharged through the paper feed channel on the baffle group. When the sensor does not detect the printed paper, it may be that there is no printed paper in the paper storage space, or the two baffles do not hold the paper roll, that is, there is a large gap between the paper roll and the baffles; if the printed paper is indeed used up, the user replenishes the paper. If the two baffles do not hold the paper roll, adjust the baffle until the sensor detects that there is printed paper in the paper feed channel. When the sensor detects that there is printed paper, that is, there is paper in the paper storage space and the two baffles hold the paper roll. The paper baffle mechanism provided in the present application is provided with a sensor on at least one baffle, which can simultaneously identify whether there is printed paper in the paper feed channel and whether the two baffles hold the paper roll.

[0040] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0041] See also Figure 1 , Figure 2 and Figure 6 One embodiment of the present application provides a paper blocking mechanism. The paper blocking mechanism includes a base 1, a baffle group and a sensor 3. The baffle group has a paper feed channel 201. The baffle group includes two baffles 2. The two baffles 2 are arranged on the base 1 and can slide relatively along a first direction X. A paper storage space 101 for placing a paper roll 4 is formed between the two baffles 2. The paper feed channel 201 and the paper storage space 101 are connected to each other to discharge the printing paper of the paper roll 4. The first direction X is parallel to the axial direction of the paper roll 4. The sensor 3 is arranged on at least one baffle 2 and is used to detect the printing paper in the paper feed channel 201.

[0042] When the paper baffle mechanism is working, the paper roll 4 is placed between the two baffles 2, and the printing paper of the paper roll 4 is discharged through the paper feed channel 201 on the baffle group. When the sensor 3 does not detect the printing paper, it may be that there is no printing paper in the paper storage space 101, or it may be that the two baffles 2 do not hold the paper roll 4, that is, there is a large gap between the paper roll 4 and the baffle 2; if the printing paper is indeed used up, the user replenishes the paper, and if the two baffles 2 do not hold the paper roll 4, the baffle 2 is adjusted until the sensor 3 detects that there is printing paper in the paper feed channel 201. When the sensor 3 detects that there is printing paper, that is, there is paper in the paper storage space 101 and the two baffles 2 hold the paper roll 4. The paper baffle mechanism provided in the present application is provided with a sensor 3 on at least one baffle 2, which can simultaneously identify whether there is printing paper in the paper feed channel 201 and whether the two baffles 2 hold the paper roll 4.

[0043] In some embodiments, the baffle 2 includes a baffle body. A paper space 101 is formed between the two baffle bodies. The baffle 2 also includes a mounting portion. The mounting portion is connected to the baffle body of the baffle 2. A paper feed channel 201 is located at the mounting portion. The mounting portion is provided with a detection channel connected to the paper feed channel 201. The sensor 3 is provided at the mounting portion and senses the printing paper in the paper feed channel 201 through the detection channel.

[0044] For the baffle 2 provided with the sensor 3, the baffle 2 includes a baffle body and a mounting portion. Compared with directly arranging the sensor 3 on the baffle body, the mounting portion can provide a stable and appropriate mounting position for the sensor 3. Furthermore, the distribution direction of the mounting portion and the baffle body of the baffle 2 where it is located is perpendicular to the first direction X, that is, the mounting portion is located along the paper output direction of the printing paper and away from the paper roll body. In this way, the sensor 3 can be effectively prevented from affecting the paper output of the paper roll 4, and at the same time, the sensor 3 can detect whether there is printing paper in the paper feeding channel 201.

[0045] like Figure 1 and Figure 4 As shown, the two baffles 2 are respectively a first baffle 21 and a second baffle 22. Taking the first baffle 21 provided with a sensor 3 as an example, the first baffle 21 includes a first baffle body 211 and a first mounting portion 212, and the second baffle 22 includes a second baffle body 221, and a paper holding space 101 is formed between the first baffle body 211 and the second baffle body 221. The first mounting portion 212 is connected to the first baffle body 211. The paper feed channel 201 is located at the first mounting portion 212, and the first mounting portion 212 is provided with a first detection channel 2123 connected to the paper feed channel 201. The sensor 3 is arranged at the first mounting portion 212 and senses the printing paper in the paper feed channel 201 through the first detection channel 2123.

[0046] When the second baffle 22 is provided with the sensor 3, the second baffle 22 further includes a second mounting portion 222, and the second mounting portion 222 is connected to the second baffle body 221. Part of the paper feeding passage 201 is located at the first mounting portion 212, and part of the paper feeding passage 201 is located at the second mounting portion 222. The second mounting portion 222 is provided with a second detection channel (not shown in the figure) connected to the paper feeding passage 201.

[0047] For example, see Figure 5 , Figure 5 The schematic diagram of the sensor 3 being arranged in the first mounting portion 212 of the first baffle 21 is shown. During installation, the signal sending component 31 of the sensor 3 is installed in the front mounting portion 2121 along the first direction X, and the signal receiving component 32 is installed in the rear mounting portion 2122 along the first direction X. During implementation, a mounting groove for facilitating the installation of the sensor 3 into the mounting portion can be provided on the side of the first mounting portion 212 away from the paper receiving space 101. After the sensor 3 is installed in place, a pressing plate is provided to block the mounting groove to prevent the sensor 3 from falling out of the first mounting portion 212, which can also play a role in dust and water prevention.

[0048] In some embodiments, the first baffle 21 further includes a first paper guide 213 , which is disposed on a side of the first mounting portion 212 close to the paper containing space 101 , and gradually moves away from the base 1 in a direction away from the paper feeding channel 201 .

[0049] The first paper guide 213 helps the printing paper to pass through the paper feeding channel 201 more smoothly, which helps to ensure that the printing paper reaches the printing position accurately. The first paper guide 213 gradually moves away from the base 1 in the direction away from the paper feeding channel 201, which helps to make paper of different thicknesses pass through the paper feeding channel 201 and the first paper guide 213 to be discharged.

[0050] In some embodiments, the second baffle 22 further includes a second paper guide 223 , which is disposed on a side of the second mounting portion 222 close to the paper containing space 101 , and the second paper guide 223 gradually moves away from the base 1 in a direction away from the paper feeding channel 201 .

[0051] The second paper guide 223 helps the printing paper to pass through the paper feeding channel 201 more smoothly, which helps to ensure that the printing paper reaches the printing position accurately. The second paper guide 223 gradually moves away from the base 1 in the direction away from the paper feeding channel 201, which helps to make paper of different thicknesses pass through the paper feeding channel 201 and the second paper guide 223 to be discharged.

[0052] In some embodiments, the baffle 2 is slidable relative to the base 1 to drive the sensor 3 to slide relative to the base 1 .

[0053] The baffle plate 2 provided with the sensor 3 is slidably connected to the base 1 , so that the sensor 3 can slide along the first direction X along with the baffle plate 2 on which it is located, which is conducive to placing the sensor 3 in the best detection position.

[0054] When only the first baffle 21 is provided with the sensor 3 and is slidably connected to the base 1, the second baffle 22 is not provided with the sensor 3 and is fixed relative to the base 1. When in use, the user places the paper roll 4 between the first baffle 21 and the second baffle 22, and makes the paper roll 4 and the second baffle 22 press against each other. When the sensor 3 on the first baffle 21 detects that there is no printing paper in the paper feeding channel 201, that is, the first baffle 21 and the second baffle 22 do not jam the paper roll 4 or the paper roll 4 has been used up, if the paper roll 4 is not jammed, adjust the first baffle 21 until the sensor 3 detects that there is paper in the paper feeding channel 201; if the paper roll 4 has been used up, replace the paper roll 4, and when placing the paper roll 4 between the first baffle 21 and the second baffle 22, ensure that the paper roll 4 and the second baffle 22 are pressed against each other, and ensure that the first baffle 21 and the second baffle 22 clamp the paper roll 4 through the sensor 3. If only the second baffle 22 is provided with the sensor 3 and is slidably connected to the base 1, the same is true for use.

[0055] When only the first baffle 21 is provided with the sensor 3, and the first baffle 21 and the second baffle 22 are both slidable relative to the base 1. When in use, the user places the paper roll 4 between the first baffle 21 and the second baffle 22, and presses the paper roll 4 against the second baffle 22. When the sensor 3 on the first baffle 21 detects that there is no printing paper in the paper feed channel 201, that is, the first baffle 21 and the second baffle 22 do not jam the paper roll 4 or the paper roll 4 has been used up. If the paper roll 4 is not jammed, the user can adjust the first baffle 21 until the sensor 3 detects that there is paper in the paper feed channel 201. The paper roll 4 can also be moved and pressed against the first baffle 21 until the sensor 3 on the first baffle 21 detects that there is paper in the paper feed channel 201, and then the second baffle 22 is adjusted until the two baffles 2 jam the paper roll 4. If the paper roll 4 has been used up and is replaced, when the paper roll 4 is placed between the first baffle 21 and the second baffle 22 , the paper roll 4 and the second baffle 22 are still ensured to be tightly pressed against each other, and the sensor 3 is used to ensure that the first baffle 21 and the second baffle 22 clamp the paper roll 4 .

[0056] When the first baffle 21 and the second baffle 22 are both provided with sensors 3 and are both slidably connected to the base 1, when the sensor 3 on the first baffle 21 detects that there is no printing paper in the paper feeding channel 201, the first baffle 21 is adjusted; when the sensor 3 on the second baffle 22 detects that there is no printing paper in the paper feeding channel 201, the second baffle 22 is adjusted. The user can adjust the corresponding first baffle 21 and / or second baffle 22 according to the detection result of the sensor 3, without adjusting the position of the paper roll 4, thereby improving the convenience of use.

[0057] See also Figure 3 In some embodiments, the first baffle 21 further includes a first toggle portion 216. The first toggle portion 216 is disposed on a side of the first baffle body 211 away from the base 1. The second baffle 22 further includes a second toggle portion 226. The second toggle portion 226 is disposed on a side of the second baffle body 221 away from the base 1.

[0058] Since the sensor 3 is arranged in the mounting portion of the baffle 2, the center of gravity of the entire baffle 2 will be close to the mounting portion. When the baffle 2 provided with the sensor 3 is slidably connected to the base 1, a toggle portion is provided on the side of the baffle body away from the base 1 and close to the mounting portion. This can provide a fulcrum for the user to toggle the baffle 2 along the first direction X, thereby facilitating the user to adjust the first baffle 21 and / or the second baffle 22.

[0059] In some embodiments, the base 1 includes a base body 11 and a connecting plate 12. The connecting plate 12 is detachably connected to the base body 11. The connecting plate 12 is provided with a guide groove. The mounting portion is slidably connected to the guide groove and is slidable relative to the guide groove along a first direction X.

[0060] When installing the baffle 2 provided with the sensor 3 and slidable relative to the base 1, first slide the mounting portion into the guide groove along the first direction X to assemble the baffle 2 and the connecting plate 12; then assemble the connecting plate 12 and the baffle 2 as a whole with the base body 11. In this way, instead of assembling and disassembling the two baffles 2 with the entire base 1, the connecting plate 12 can be detachably connected to the base body 11, further simplifying the installation process. At the same time, the guide groove on the connecting plate 12 makes the sliding of the baffle 2 in the first direction X more stable, reducing the shaking feeling when adjusting the baffle 2.

[0061] like Figure 1 and Figure 8As shown, taking the example that both the first baffle plate 21 and the second baffle plate 22 are provided with the sensor 3 and are slidably connected to the connecting plate 12, the connecting plate 12 is provided with a first guide groove 121 and a second guide groove 122 along the first direction X. The first mounting portion 212 is slidably connected to the first guide groove 121 along the first direction X, and the second mounting portion 222 is slidably connected to the second guide groove 122 along the first direction X. During installation, along the first direction X, the first mounting portion 212 is slid into the first guide groove 121, and the second mounting portion 222 is slid into the second guide groove 122 to complete the assembly of the baffle group and the connecting plate 12. In some embodiments, a baffle slide groove 1001 is formed between the base body 11 and the connecting plate 12, and the first baffle body 211 and the second baffle body 221 are both slidably connected to the baffle slide groove 1001 and can both move along the first direction X. In this way, the baffle slide 1001 together with the first guide groove 121 and the second guide groove 122 can ensure that the baffle assembly slides more accurately along the first direction X, which helps to ensure paper output and printing quality. When the baffle 2 needs to be repaired and replaced, it is also convenient to assemble and disassemble.

[0062] See also Figure 2 , Figure 4 and Figure 7 In some embodiments, when the first baffle 21 is slidably connected to the base 1 along the first direction X, the first baffle 21 further includes a first slider 214. A paper storage space 101 is formed between the first baffle body 211 and the second baffle body 221. The first slider 214 is connected to the first baffle body 211, and the distribution direction of the first slider 214 and the first baffle body 211 is perpendicular to the first direction X. The first slider 214 is slidably connected to the baffle slide 1001 so that the first baffle 21 can move along the first direction X. When the second baffle 22 is slidably connected to the base 1 along the first direction X, the second baffle 22 further includes a second slider 224. The second slider 224 is connected to the second baffle body 221, and the distribution direction of the second slider 224 and the second baffle body 221 is perpendicular to the first direction X. The second slider 224 is slidably connected to the baffle slide 1001 so that the second baffle 22 can move along the first direction X.

[0063] The first slider 214 of the first baffle 21 and the second slider 224 of the second baffle 22 are both slidably connected to the baffle groove 1001. The baffle groove 1001 can provide a guiding function, so that the first baffle 21 and / or the second baffle 22 can stably slide along the first direction X, effectively reducing the shaking caused by adjusting the baffle 2, and helping the first baffle 21 and / or the second baffle 22 to stably support the paper roll 4, so that the first baffle 21 and the second baffle 22 can also clamp the paper roll 4 more stably.

[0064] In some embodiments, the baffle slot 1001 penetrates the base 1 along the second direction Y, the first baffle 21 further includes a first stopper 215, the first slider 214 and the first stopper 215 are detachably connected, and the first stopper 215 and the first baffle body 211 are distributed on both sides of the baffle slot 1001 along the second direction Y to stop the first slider 214 from leaving the baffle slot 1001. The second baffle 22 further includes a second stopper 225. The second slider 224 and the second stopper 225 are detachably connected, and the second stopper 225 and the second baffle body 221 are distributed on both sides of the baffle slot 1001 along the second direction Y to stop the second slider 224 from leaving the baffle slot 1001. The second direction Y is perpendicular to the first direction X and away from the paper storage space 101.

[0065] The baffle groove 1001 penetrates the base 1 along the second direction Y, and the first baffle 21 and the second baffle 22 can be directly placed into the baffle groove 1001 along the second direction Y without being installed into the groove along the first direction X. The sliding connection assembly between the baffle group and the base 1 is more convenient, and the first stop block 215 and the second stop block 225 are used to stop the first slider 214 and the second slider 224 from disengaging, which helps to ensure that the sliding of the first baffle 21 and the second baffle 22 relative to the base 1 is stable and reliable.

[0066] In some embodiments, at least one of the first slider 214 and the baffle groove 1001 has a sliding bar structure so that there is linear friction between the first slider 214 and the baffle groove 1001; in this way, when the first baffle 21 slides along the first direction X, the blocking feeling caused by the sliding friction can be reduced, making the first baffle 21 slide more smoothly.

[0067] In some embodiments, at least one of the second slider 224 and the baffle groove 1001 has a sliding bar structure so that there is linear friction between the second slider 224 and the baffle groove 1001; in this way, when the second baffle 22 slides along the first direction X, the blocking feeling caused by the sliding friction can be reduced, making the second baffle 22 slide more smoothly.

[0068] After the sensor 3 is mounted on the first baffle 21 and / or the second baffle 22, the first baffle 21 and the second baffle 22 are slidably connected to the connecting plate 12 along the first direction X, the first mounting portion 212 is located in the first guide groove 121 and can slide along the first direction X, and the second mounting portion 222 is located in the second guide groove 122 and can slide along the first direction X. A snap-fit ​​structure is provided between the connecting plate 12 and the base body 11, and then the connecting plate 12 together with the baffle assembly is snapped into the base body 11 along the second direction Y, the first slider 214 and the second slider 224 are located in the baffle slide groove 1001, and then the first stop block 215 and the second stop block 225 are installed. Furthermore, screws can be used to fix the connecting plate 12 and the base body 11.

[0069] See also Figure 5 and Figure 6 In some embodiments, the number of mounting parts is two. The two mounting parts are respectively a front mounting part 2121 and a rear mounting part 2122. The front mounting part 2121 and the rear mounting part 2122 are arranged at intervals. The side of the front mounting part 2121 away from the paper storage space 101 and the side of the rear mounting part 2122 away from the paper storage space 101 are connected. The rear mounting part 2122 is slidably connected to the guide groove. The paper feeding channel 201 is located between the front mounting part 2121 and the rear mounting part 2122. The sensor 3 includes a signal sending part 31 and a signal receiving part 32. The signal sending part 31 is arranged at the front mounting part 2121. The signal receiving part 32 is arranged at the rear mounting part 2122. The detection channel is connected between the front mounting part 2121 and the rear mounting part 2122 and intersects with the paper feeding channel 201.

[0070] Thus, when the signal sent by the signal sending element 31 is received by the signal receiving element 32, it means that there is no printing paper in the paper feeding passage 201; otherwise, it means that there is paper in the paper feeding passage 201. A part of the front mounting portion 2121 is connected to the rear mounting portion 2122, and the rear mounting portion 2122 is slidably connected to the first guide groove 121. There is an assembly between the two mounting portions and the connecting plate 12 to improve the connection strength between the baffle 2 and the base 1.

[0071] The sensor 3 may also be a photoelectric sensor 3 , and the light path / signal emitted by the sensor 3 is blocked, that is, there is paper in the paper feeding channel 201 .

[0072] In some embodiments, one baffle 2 is provided with a sensor 3 , the baffle 2 is fixed to the base 1 , and the other baffle 2 is slidably connected to the base 1 .

[0073] The baffle 2 with the sensor 3 is fixed relative to the base 1, and the other baffle 2 does not need to be provided with the sensor 3 but can slide relative to the base 1, and can also detect whether there is printing paper in the paper feeding channel 201 and whether the two baffles 2 clamp the paper roll 4.

[0074] If the sensor 3 is disposed on the first baffle 21, and the first baffle 21 is fixed, the second baffle 22 can slide along the first direction X, and when the paper roll 4 is placed between the first baffle 21 and the second baffle 22, it is always ensured that the paper roll 4 and the second baffle 22 are pressed tightly. When the sensor 3 on the first baffle 21 detects that there is no printing paper in the paper feeding channel 201, that is, the first baffle 21 and the second baffle 22 do not jam the paper roll 4 or the paper roll 4 has been used up, if the paper roll 4 is not jammed, the second baffle 22 and the paper roll 4 are adjusted until the sensor 3 detects that there is paper in the paper feeding channel 201; if the paper roll 4 has been used up, the paper roll 4 is replaced, and when the paper roll 4 is placed between the first baffle 21 and the second baffle 22, it is still ensured that the paper roll 4 and the second baffle 22 are pressed tightly, and the sensor 3 is used to ensure that the first baffle 21 and the second baffle 22 jam the paper roll 4.

[0075] If the sensor 3 is disposed on the second baffle 22, and the second baffle 22 is fixed, the first baffle 21 can slide along the first direction X, and when the paper roll 4 is placed between the first baffle 21 and the second baffle 22, it is always ensured that the paper roll 4 and the first baffle 21 are pressed tightly. When the sensor 3 on the second baffle 22 detects that there is no printing paper in the paper feeding channel 201, that is, the first baffle 21 and the second baffle 22 do not block the paper roll 4 or the paper roll 4 has been used up, if the paper roll 4 is not blocked, the first baffle 21 and the paper roll 4 are adjusted until the sensor 3 detects that there is paper in the paper feeding channel 201; if the paper roll 4 has been used up, the paper roll 4 is replaced, and when the paper roll 4 is placed between the first baffle 21 and the second baffle 22, it is still ensured that the paper roll 4 and the first baffle 21 are pressed tightly, and the sensor 3 is used to ensure that the first baffle 21 and the second baffle 22 clamp the paper roll 4.

[0076] In some embodiments, there are multiple sensors 3 , and the multiple sensors 3 are distributed along a direction perpendicular to the first direction X.

[0077] On the baffle 2 provided with the sensor 3, there are multiple sensors 3 and they are distributed along a direction perpendicular to the first direction X; when multiple sensors 3 are distributed along the paper output direction, that is, multiple sensors 3 are arranged at intervals along the paper output direction, along the paper output direction, some sensors detect that there is no paper in the paper feed channel 201 and another part of sensors detect that there is paper in the paper feed channel 201, indicating that a paper jam has occurred. When multiple sensors 3 are distributed on both sides of the paper feed channel 201 along the paper output direction, multi-point detection can be performed on the printing paper passing through the paper feed channel 201, further improving the detection accuracy.

[0078] The multiple sensors 3 can be arranged on the first baffle 21 and distributed along the first direction X, or can be arranged on the second baffle 22 and distributed along the first direction X. Taking the case where the first baffle 21 is provided with multiple sensors 3 as an example, when some sensors 3 sense that there is paper, but other sensors 3 cannot sense printing paper, it can be confirmed that the baffle group does not clamp the paper roll 4 tightly, and when all sensors 3 cannot sense printing paper, it can be confirmed that paper needs to be replenished; the second baffle 22 is provided with multiple sensors in the same manner.

[0079] When multiple sensors 3 are provided on both the first baffle 21 and the second baffle 22 along the first direction X. If some sensors 3 on the first baffle 21 sense the presence of paper, but other sensors 3 cannot sense the printing paper, it can be confirmed that the first baffle 21 is not pressed against the paper roll 4. If some sensors 3 on the second baffle 22 sense the presence of paper, but other sensors 3 cannot sense the printing paper, it can be confirmed that the second baffle 22 is not pressed against the paper roll 4. In both cases, only the first baffle 21 or the second baffle 22 needs to be adjusted. If the above situation occurs on both the first baffle 21 and the second baffle 22, both the first baffle 21 and the second baffle 22 need to be adjusted. When all sensors on the first baffle 21 and the second baffle 22 sense the printing paper, there is paper in the paper holding space 101 and the baffle group has jammed the paper roll 4.

[0080] In some embodiments, there are multiple sensors 3 , and the multiple sensors 3 are distributed along the first direction X.

[0081] On the baffle 2 provided with sensors 3, there are multiple sensors 3 distributed along the first direction X. When some sensors 3 sense the presence of paper but other sensors 3 cannot sense the printing paper, it can be confirmed that the baffle group does not clamp the paper roll 4. When all sensors 3 cannot sense the printing paper, it can be confirmed that paper needs to be replenished.

[0082] In some embodiments, the base 1 includes a base body 11 and a connecting plate 12, and the connecting plate 12 is detachably connected to the base body 11; a baffle groove 1001 is formed between the base body 11 and the connecting plate 12, and both baffles 2 are slidably connected to the baffle groove 1001.

[0083] The two baffles 2 are slidably connected to the base 1 via a baffle sliding groove 1001, so that the structural coordination between the baffle group and the base 1 is simpler.

[0084] See also Figure 1 and Figure 2 An embodiment of the present application provides a printer 200, and the printer 200 includes a paper stop mechanism.

[0085] In the above embodiment, the printer 200 includes a paper stop mechanism, and a sensor 3 is provided on at least one baffle 2, which is beneficial to ensure that whether there is printing paper in the paper feeding channel 201 and whether the two baffles 2 are jammed with the paper roll 4 can be simultaneously identified, which helps to improve the printing quality.
