Description

Technical Field

[0001] This invention relates to the field of printer technology, and more particularly to a paper waste discharge mechanism, a pull gauge device, and a printer. Background Technology

[0002] When the printer is printing, the paper path continuously feeds paper to the paper guide device. The paper guide device positions the paper and then feeds it to the printing end for printing. During the continuous paper feeding process, if the paper path stops slightly or a paper jam occurs, two adjacent sheets of paper may partially overlap. The overlapping paper may enter the paper guide device, which may cause the paper guide device to jam and malfunction. Even if the paper guide device does not jam, misprints may still occur.

[0003] Therefore, there is an urgent need for a paper waste discharge mechanism, a guide device, and a printer to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a paper waste removal mechanism, a paper guide device, and a printer, which can remove overlapping paper, prevent the paper guide device from jamming, and avoid misprinting by the printer.

[0005] To achieve this objective, the present invention adopts the following technical solution: In a first aspect, a paper waste discharge mechanism is provided for discharging waste paper, the paper waste discharge mechanism comprising: frame; Waste discharge assembly, which is installed on the frame and has a waste discharge channel inside; A switching component includes a support member and a first drive member. A paper support space is formed above the support member. The first drive member is mounted on the frame and its output shaft is connected to the support member. The support member has a waste discharge position where the paper support space communicates with the waste discharge channel and a paper feeding position where the paper support space avoids the waste discharge channel. The first drive member is configured to drive the support member to move to switch between the waste discharge position and the paper feeding position.

[0006] In some embodiments, the switching assembly further includes a connecting rod shaft, one end of which is connected to the support member and the other end of which is connected to the output shaft of the first drive member. The first drive member is configured such that the output shaft can move along its own axial direction to drive the connecting rod shaft to rotate. The rotation of the connecting rod shaft can drive the support member to switch between the paper feeding position and the waste discharge position.

[0007] In some embodiments, the first driving element includes an electromagnetic coil and a magnetic body. The electromagnetic coil is mounted on the frame and has a coil space inside it. The magnetic body is movably mounted in the coil space and one end is connected to the connecting rod shaft.

[0008] In some embodiments, the paper waste discharge mechanism further includes a limiting component, which includes a first limiting member and a second limiting member. When the support member is in the waste discharge position, the connecting rod shaft abuts against the first limiting member, and when the support member is in the paper feeding position, the connecting rod shaft abuts against the second limiting member.

[0009] In some embodiments, both the first limiting member and the second limiting member are movably connected to the frame and can move away from or close to each other.

[0010] In some embodiments, the waste discharge assembly includes a first guide and a second guide, both mounted on the frame, the first guide and the second guide being spaced apart from each other and sandwiched to form the waste discharge channel.

[0011] In some embodiments, the waste discharge assembly further includes a first conveying roller and a second driving member. The second driving member is mounted on the first guide and its output shaft is coaxially connected to the roller shaft of the first conveying roller. The second driving member is configured to drive the first conveying roller to rotate. The roller shaft of the first conveying roller is perpendicular to the conveying direction of the paper located in the waste discharge channel. The roller surface of the first conveying roller can contact the paper surface of the paper located in the waste discharge channel.

[0012] In some embodiments, the waste discharge assembly further includes a second conveying roller, which is rotatably connected to the second guide with its roller shaft as the pivot and the roller shaft axis is parallel to the roller shaft axis of the first conveying roller. The second conveying roller is disposed opposite to the first conveying roller and is used to clamp the paper surface of the paper located in the waste discharge channel.

[0013] Secondly, a guide device is provided, including a guide mechanism and the aforementioned paper waste discharge mechanism. The guide mechanism includes a paper inlet, and the frame is fixedly connected to the guide mechanism. When the support member is in the paper feeding position, the paper support space is connected to the paper inlet.

[0014] Thirdly, a printer is provided, the printer including a paper path and a paper waste discharge mechanism as described above, the frame being fixedly connected to the paper path.

[0015] The beneficial effects of this invention are: The paper waste removal mechanism provided in this embodiment has a waste removal component installed on the frame and an internal waste removal channel. A paper support space is formed above the support member. A first drive member is installed on the frame and its output shaft is connected to the support member. The first drive member is configured to drive the support member to move and switch between a waste removal position where the paper support space communicates with the waste removal channel and a paper feeding position where the paper support space avoids the waste removal channel. When there is a slight pause or paper jam in the paper path of the printer, when two adjacent overlapping sheets of paper are fed to the support member, the first drive member drives the support member to move from the paper feeding position to the waste removal position, aligning the paper on the support member with the waste removal channel, changing the paper feeding direction, so that the paper enters the waste removal channel instead of continuing to be fed along the paper feeding direction to the guide mechanism, avoiding paper jams in the guide mechanism and preventing misprinting by the printer.

[0016] The guide plate device provided in this embodiment includes a guide plate mechanism and a paper waste discharge mechanism. The frame is fixedly connected to the guide plate mechanism. When the support is in the paper feeding position, the paper support space is connected to the paper inlet of the guide plate mechanism, thereby preventing overlapping paper from entering the guide plate device and causing the guide plate device to jam.

[0017] The printer provided in this embodiment includes a paper path and a paper waste removal mechanism, with the frame fixedly connected to the paper path, thereby preventing misprinting. Attached Figure Description

[0023] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Figure 1 A schematic diagram of the structure of the pull gauge device provided in an embodiment of the present invention is shown. Figure 2 A schematic diagram of the paper waste discharge mechanism provided in an embodiment of the present invention is shown. Figure 3 It shows Figure 1 A magnified view of a portion of point A in the diagram. (See diagram below.) Figures 1 to 3As shown, this embodiment provides a paper waste removal mechanism. When the paper waste removal mechanism is installed in a printer, if the printer paper path experiences a slight pause or paper jam, the paper waste removal mechanism is used to remove overlapping paper. The paper waste removal mechanism includes a frame 1, a waste removal component 2, and a switching component 3. The waste removal component 2 is installed on the frame 1 and has a waste removal channel 20 inside. The switching component 3 includes a support member 31 and a first drive member 32. A paper support space 30 is formed above the support member 31. The first drive member 32 is installed on the frame 1 and its output shaft is connected to the support member 31. The support member 31 has a waste removal position where the paper support space 30 communicates with the waste removal channel 20 and a paper feeding position where the paper support space 30 avoids the waste removal channel 20. The first drive member 32 is configured to drive the support member 31 to move to switch between the waste removal position and the paper feeding position.

[0025] The paper waste removal mechanism provided in this embodiment has a waste removal component 2 installed on the frame 1 and a waste removal channel 20 inside. A paper support space 30 is formed above the support member 31. A first drive member 32 is installed on the frame 1 and its output shaft is connected to the support member 31. The first drive member 32 is configured to drive the support member 31 to move and switch between a waste removal position where the paper support space 30 communicates with the waste removal channel 20 and a paper feeding position where the paper support space 30 avoids the waste removal channel 20. When there is a slight pause or paper jam in the paper path of the printer, when two adjacent overlapping sheets of paper are fed to the support member 31, the first drive member 32 drives the support member 31 to move from the paper feeding position to the waste removal position, aligning the paper on the support member 31 with the waste removal channel 20, changing the paper feeding direction, so that the paper enters the waste removal channel 20 instead of continuing to be fed into the guide mechanism 100 along the paper feeding direction, avoiding paper jams in the guide device and preventing misprinting by the printer.

[0026] It should be noted that printers are often equipped with photoelectric sensors to detect whether the paper is overlapping, which will not be described in detail here.

[0027] It should be noted that the paper waste discharge mechanism is not limited in its installation position relative to the printer. It can be installed at the paper inlet of the pull-beam mechanism 100. When the support member 31 is in the clearance position, the paper support space 30 of the support member 31 is directly connected to the paper inlet of the pull-beam mechanism 100. The paper can enter the pull-beam mechanism 100 for pulling and positioning through the paper support space 30 and the paper inlet of the pull-beam mechanism 100. When the paper overlaps, the first drive member 32 drives the support member 31 to move from the paper feeding position to the waste discharge position, aligning the paper on the support member 31 with the waste discharge channel 20, changing the paper feeding direction, so that the paper enters the waste discharge channel 20 instead of continuing to be fed into the pull-beam mechanism 100 through the paper inlet along the paper feeding direction. The paper waste discharge mechanism can also be installed at any position on the paper path. When the support member 31 is in the avoidance position, the paper support space 30 of the support member 31 is not connected to the paper path and the waste discharge channel 20. The paper is normally transported on the paper path. When the paper path experiences a slight pause or paper jam, the first drive member 32 drives the support member 31 to move from the paper feeding position to the waste discharge position. One end of the paper support space 30 is connected to the paper path, and the other end is connected to the waste discharge channel 20, changing the paper feeding direction so that the paper enters the waste discharge channel 20 instead of continuing to move along the paper feeding direction.

[0028] It should be noted that the specific type of the first driving component 32 is not limited here. It can be a motor, cylinder, hydraulic cylinder or electromagnetic component. Those skilled in the art can reasonably select the first driving component 32 according to actual needs, and will not be described in detail here.

[0029] like Figures 1 to 3As shown, the switching assembly 3 also includes a connecting shaft 33. One end of the connecting shaft 33 is connected to the support member 31, and the other end is connected to the output shaft of the first drive member 32. The first drive member 32 is configured such that its output shaft can move along its own axial direction to drive the connecting shaft 33 to rotate. The rotation of the connecting shaft 33 can drive the support member 31 to switch between the paper feeding position and the waste discharge position. Thus, the output shaft of the first drive member 32 only needs to move along its own axial direction to enable the support member 31 to switch between the paper feeding position and the clearance position, thereby reducing the volume of the first drive member 32 and the overall volume of the switching assembly 3, so that the paper waste discharge mechanism can be installed more flexibly on the pull gauge mechanism 100 or the paper path. Specifically, the connecting rod shaft 33 includes a first connecting rod 331 and a second connecting rod 332. One end of the first connecting rod 331 is rotatably connected to the frame 1, and the other end is rotatably connected to one end of the second connecting rod 332. The output shaft of the first driving member 32 is rotatably connected to the first connecting rod 331, and the other end of the second connecting rod 332 is connected to the support member 31. Thus, the output shaft of the first driving member 32 can move along its own axial direction, causing the first connecting rod 331 to rotate and drive the second connecting rod 332 to rotate. Then, the rotation of the second connecting rod 332 drives the support member 31 to rotate, thereby switching between the paper feeding position and the avoidance position.

[0030] Preferably, the first driving component 32 includes an electromagnetic coil 321 and a magnetic body 322. The electromagnetic coil 321 is mounted on the frame 1 and has a coil space inside. The magnetic body 322 is movably mounted in the coil space and one end is connected to the connecting rod shaft 33, so that the electromagnetic coil 321 can be energized to generate a Lorentz force and change the position of the magnetic body 322 in the coil, so that the connecting rod shaft 33 rotates and the support component 31 switches between the paper feeding position and the avoidance position, reducing the overall volume of the switching component 3, and allowing the paper waste discharge mechanism to be installed more flexibly on the pull gauge mechanism 100 or the paper path.

[0031] It should be noted that the specific type of magnetic body 322 is not limited here. It can be a magnet, a lodestone, an iron core or a copper core. Those skilled in the art can make reasonable selections according to actual needs, and will not be elaborated here.

[0032] Continue as Figures 1 to 3 As shown, the paper waste discharge mechanism also includes a limiting component 4, which includes a first limiting member 41 and a second limiting member 42. When the support member 31 is in the waste discharge position, the connecting rod shaft 33 abuts against the first limiting member 41. When the support member 31 is in the paper feeding position, the connecting rod shaft 33 abuts against the second limiting member 42, thereby limiting the maximum displacement distance of the support member 31. This allows the support member 31 to switch only between the paper feeding position and the avoidance position, improving the waste discharge reliability of the paper waste discharge mechanism and preventing the paper from failing to enter the waste discharge channel 20 when waste paper needs to be discharged because the waste discharge channel position 20 and the paper support space 30 cannot be aligned and connected.

[0033] Preferably, both the first limiting member 41 and the second limiting member 42 are movably connected to the frame 1 and can move away from or closer to each other, thereby adjusting the movement range of the support member 31. When the support member 31 abuts against the first limiting member 41, the waste discharge channel 20 communicates with the paper support space 30, allowing paper to enter the waste discharge channel 20. When the support member 31 abuts against the second limiting member 42, the paper can be normally conveyed in the paper path without entering the waste discharge channel 20, improving the waste discharge reliability of the paper waste discharge mechanism. Specifically, the frame 1 is provided with a first threaded hole and a second threaded hole, with parallel holes. The first limiting member 41 is threaded to the first threaded hole, and the second limiting member 42 is threaded to the second threaded hole. By rotating the first limiting member 41 and the second limiting member 42, the distance between them can be adjusted, allowing the operator to easily adjust the movement range of the support member 31. When the support member 31 is in the waste discharge position, the waste discharge channel 20 and the paper support space 30 can be aligned and communicated, improving the waste discharge reliability of the paper waste discharge mechanism.

[0034] Continue as Figures 1 to 3 As shown, the waste discharge assembly 2 includes a first guide 21 and a second guide 22 both mounted on the frame 1. The first guide 21 and the second guide 22 are spaced apart from each other and clamped to form a waste discharge channel 20. After the paper enters the waste discharge channel 20, the first guide 21 and the second guide 22 can constrain the movement direction of the paper, preventing the paper from curling up and getting stuck in the waste discharge channel 20, thereby improving the reliability of the paper waste discharge mechanism.

[0035] Continue as Figures 1 to 3 As shown, the waste discharge assembly 2 also includes a first conveying roller 23 and a second driving member (not shown in the figure). The second driving member is mounted on the first guide member 21 and its output shaft is coaxially connected to the roller shaft of the first conveying roller 23. The second driving member is configured to drive the first conveying roller 23 to rotate. The roller shaft axis of the first conveying roller 23 is perpendicular to the conveying direction of the paper located in the waste discharge channel 20. The roller surface of the first conveying roller 23 can contact the paper surface located in the waste discharge channel 20. Thus, after the paper enters the waste discharge channel 20, the second driving member can drive the paper to move, avoiding the paper from losing power and failing to discharge from the waste discharge channel 20 after entering the waste discharge channel 20, causing paper jams, and improving the reliability of the paper waste discharge mechanism.

[0036] Preferably, the waste discharge assembly 2 further includes a second conveying roller 24, which is rotatably connected to the second guide member 22 with its roller shaft as the pivot and the roller shaft axis is parallel to the roller shaft axis of the first conveying roller 23. The second conveying roller 24 is arranged opposite to the first conveying roller 23 and is used to clamp the paper surface of the paper located in the waste discharge channel 20, thereby clamping the paper located in the waste discharge channel 20 so that the paper can move reliably in the waste discharge channel 20.

[0037] Furthermore, at least two first conveying rollers 23 are spaced apart along a direction perpendicular to the conveying direction of the paper located in the waste discharge channel 20, and the number of second conveying rollers 24 is the same as that of the first conveying rollers 23 and they are arranged opposite to each other, thereby clamping the paper located in the waste discharge channel 20 at multiple points and preventing the paper from curling up and getting stuck in the waste discharge channel 20.

[0038] This embodiment also provides a guide device, including a guide mechanism 100 and a paper waste discharge mechanism. The frame 1 is fixedly connected to the guide mechanism 100. When the support member 31 is in the paper feeding position, the paper support space 30 is connected to the paper inlet 101 of the guide mechanism 100, thereby preventing overlapping paper from entering the guide device and causing the guide device to jam.

[0039] This embodiment also provides a printer, which includes a paper path and a paper waste discharge mechanism. The frame 1 is fixedly connected to the paper path, thereby preventing misprinting.

[0040] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
