Description

Technical Field

[0001] The utility model relates to the field of printing equipment, in particular to a paper separating piece and a printer. Background Art

[0002] In the prior art, in office document printers, in order to ensure that only one sheet of paper is fed each time printing, the printer has a paper separator to ensure that only one sheet of paper is fed each time printing. Figure 10 The pickup roller transports the paper from the paper hopper to the paper separation surface of the paper separation unit for paper separation. Since each paper hopper has a specified paper capacity, there will be two states: too much paper and too little paper. The most direct impact of too much paper is that the angle and position of the paper entering the paper separation surface will be inconsistent, sometimes affecting the smooth entry of the paper and thus the paper separation effect.

[0014] From the above description of the present invention and its preferred embodiments, it can be seen that, compared with the prior art, the technical solution of the present invention and its preferred embodiments have the following beneficial effects due to the adoption of the following technical means:

[0015] 1. Scheme 1 and its preferred embodiment, a paper separator, which is suitable for use in a printer, is provided with a paper separation surface and a transition surface; the transition surface is connected to the paper separation surface, and the plane where the transition surface is located does not overlap with the plane where the paper separation surface is located, ensuring that the paper feeding angles of the two are different. The transition surface is located in front of the paper separation surface, and the transition surface is suitable for receiving the paper rubbed in by the paper pickup roller, and allowing the paper to enter the paper separation surface from the transition surface. Regardless of whether there is a lot of paper or a little paper, the paper first contacts the transition surface and then contacts the paper separation surface. Since the position between the transition surface and the paper separation surface is relatively fixed, the position and angle of the paper entering the paper separation surface from the transition surface are always consistent. By reasonably designing the relative relationship between the transition surface and the paper separation surface, the angle and position of the paper entering the paper separation surface from the transition surface are more reasonable, which facilitates the paper to enter the paper separation surface, thereby making it easier to achieve the paper separation effect.

[0016] In addition, the paper separation surface and the transition surface are both arranged on the paper separation component, and there is no need to add additional parts to realize the corresponding functions. The solution is simpler. Moreover, since the paper separation surface and the transition surface are both located on the same component, the relative relationship between the paper separation surface and the transition surface is also easy to process.

[0017] 2. In the second solution and its preferred embodiment, the transition surface is a convex arc surface.

[0019] 4. In the fourth solution and its preferred embodiment, the transition surface is an inclined surface, which can guide the paper to the paper separation surface.

[0020] 5. In the fifth solution and its preferred embodiment, the transition surface and the paper separation surface are transitioned by rounded corners. The rounded corner transition makes the connection between the transition surface and the paper separation surface smoother, making it easier for paper to enter the paper separation surface.

The paper separation board is provided with a paper separation surface and a transition surface.

The paper separation effect is enhanced by providing the paper separation sheet.

The printer also includes a frame, a paper pickup roller and a first biasing member. The paper pickup roller is rotatably connected to the frame to pick up paper; the two ends of the first biasing member act on the paper separating member and the frame respectively to apply a force to the paper separating member to move the paper separating member toward the paper pickup roller, so that the paper separating member and the paper pickup roller can clamp the paper to achieve the paper separation effect.

[0023] 8.

[0024] 9. In Scheme 9 and its preferred embodiments, the end of the paper storage board away from the paper pickup roller is hinged to the frame, the second biasing member applies force to the paper storage board and causes the paper storage board to rotate around its rotation axis. The end of the paper storage board close to the paper pickup roller is higher than the end away from the paper pickup roller. Rotating the paper top is simpler than vertically sliding the paper top. Rotating the paper top will result in inconsistent angles and positions of the paper entering the paper separation surface when there is a lot of paper or a little paper, which affects the paper separation effect. This problem will be improved by the structure of the above-mentioned paper separation member. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] In the claims, specification and the above drawings of the present utility model, unless otherwise clearly defined, if the terms "fixed connection" or "fixed connection" are used, they should be understood in a broad sense, that is, any connection method without any displacement relationship and relative rotation relationship between the two parties, that is to say, including non-detachable fixed connection, detachable fixed connection, integral connection and fixed connection through other devices or elements.

[0042] In the claims, description and drawings of the present utility model, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0043] refer to Figures 1-9 A printer includes a paper separation member 1, a frame 2, a paper pickup roller (not shown in the figure), a first biasing member (not shown in the figure), a paper storage board 3 and a second biasing member 4.

[0044] The frame 2 is used to install various components of the printer.

[0045] The pickup roller is rotatably connected to the frame 2 to pick up paper. In this embodiment, the pickup roller is of a special shape, and its cross-section is approximately D-shaped.

[0046] The two ends of the first biasing member act on the paper separating member 1 and the frame 2 respectively to apply a force to the paper separating member 1 to move the paper separating member 1 toward the paper pickup roller. The first biasing member can be a spring, rubber, or two magnetically matched elements that repel or attract each other. In this embodiment, the first biasing member is a spring.

[0047] refer to Figure 2 The paper storage board 3 is suitable for storing paper 5, and multiple papers 5 are stacked on the paper storage board 3. One end of the paper storage board 3 away from the paper pickup roller is hinged to the frame 2.

[0048] refer to Figure 2 The ends of the second biasing member 4 act on the paperboard accumulator 3 and the frame 2, respectively, exerting a force on the paperboard accumulator 3, causing it to move toward the pickup roller, thereby allowing the paperboard accumulator 3 and the pickup roller to jointly clamp the paper 5. In this embodiment, the second biasing member 4 applies a force to the paperboard accumulator 3, causing it to rotate about its rotation axis, with the end of the paperboard accumulator 3 closer to the pickup roller being higher than the end farther from the pickup roller. In this embodiment, the second biasing member 4 is a spring.

[0049] refer to Figure 4-Figure 6 The paper separation member 1 is rotatably connected to the frame 2 and includes a paper separation board 11 and a paper separation sheet 12. The paper separation board 11 has a paper separation surface 111, a transition surface 112, and a paper separation slot 113. The paper separation slot 113 opens on the paper separation surface 111, and the paper separation sheet 12 is installed in the paper separation slot 113. The paper separation board 11 is acted upon by a first biasing member, causing the paper separation sheet 12 to abut against the pickup roller. The paper separation sheet 12 can have a large friction coefficient to facilitate paper separation.

[0050] In this embodiment, reference Figure 3 When the paper separation member 1 is installed, the paper separation surface 111 is an inclined surface inclined relative to the horizontal plane.

[0051] refer to Figure 3 The transition surface 112 is connected to the paper separation surface 111, and the plane of the transition surface 112 does not overlap with the plane of the paper separation surface 111. The transition surface 112 is located in front of the paper separation surface 111, that is, the paper 5 passes through the transition surface 112 before passing through the paper separation surface 111. The transition surface 112 is suitable for receiving the paper 5 picked up by the paper pickup roller and allowing the paper 5 to enter the paper separation surface 111 along the transition surface 112 for paper separation.

[0052] The shape of the transition surface 112 can be one of the following:

[0053] ①Reference Figure 9 , the transition surface 112 is a convex arc surface. ② Reference Figure 4-Figure 6 , the transition surface 112 is a concave arc surface. ③ Reference Figure 7 The transition surface 112 is a concave arc surface, and the transition surface 112 and the paper separation surface 111 are transitioned through a rounded corner 114. Figure 8 ⑤ The transition surface 112 is an inclined surface, and the transition surface 112 and the paper separation surface 111 are transitioned through a rounded corner 114 .

[0054] In the above description, because the second biasing member 4 applies a force inclined relative to the horizontal plane to the paperboard storage 3 and causes the paperboard storage 3 to move in the inclined direction, the angle between the upper surface of the topmost paper 5 and the paper separation surface 111 is smaller when there is a large amount of paper than when there is a small amount of paper. Therefore, when there is a large amount of paper, the paper 5 needs to bend more to enter the paper separation surface 111, making paper separation more difficult. In addition, the position of the paper 5 and the paper pickup roller will also change when there is a large amount of paper or a small amount of paper. When there is a large amount of paper, the position where the paper 5 contacts the paper separation surface 111 is further downward, making paper feeding more difficult. Therefore, if the paper 5 enters the paper separation surface 111 directly, the feeding position and angle will affect the feeding of the paper 5.

[0055] In this embodiment, regardless of whether there is a lot of paper or a little paper, the paper 5 first contacts the transition surface 112 and then contacts the paper separation surface 111. Since the positions between the transition surface 112 and the paper separation surface 111 are relatively fixed, the position and angle of the paper 5 entering the paper separation surface 111 from the transition surface 112 are always consistent. By reasonably designing the relative relationship between the transition surface 112 and the paper separation surface 111, the angle and position of the paper 5 entering the paper separation surface 111 from the transition surface 112 are more reasonable (such as the required bending angle is small and the entry position is higher), which facilitates the paper 5 to enter the paper separation surface 111 and achieve the paper separation effect.

[0056] Compared with the prior art, this embodiment has the following beneficial effects:

[0057] In an exemplary embodiment, a paper separation component 1 is suitable for use in a printer, and is provided with a paper separation surface 111 and a transition surface 112; the transition surface 112 is connected to the paper separation surface 111, and the plane where the transition surface 112 is located does not overlap with the plane where the paper separation surface 111 is located, ensuring that the paper feeding angles of the two are different. The transition surface 112 is located at the front side of the paper separation surface 111. The transition surface 112 is suitable for receiving the paper 5 picked up by the paper pickup roller and allowing the paper 5 to enter the paper separation surface 111 from the transition surface 112. Regardless of whether there is a lot of paper or a little paper, the paper 5 first contacts the transition surface 112 and then contacts the paper separation surface 111. Since the positions between the transition surface 112 and the paper separation surface 111 are relatively fixed, the position and angle of the paper 5 entering the paper separation surface 111 from the transition surface 112 are always consistent. By reasonably designing the relative relationship between the transition surface 112 and the paper separation surface 111, the angle and position of the paper 5 entering the paper separation surface 111 from the transition surface 112 are more reasonable, which facilitates the paper 5 to enter the paper separation surface 111, thereby making it easier to achieve the paper separation effect.

[0058] In addition, the paper separation surface 111 and the transition surface 112 are both arranged on the paper separation component 1, and there is no need to add additional parts to realize the corresponding functions. The solution is simpler. Moreover, since the paper separation surface 111 and the transition surface 112 are both located on the same component, the relative relationship between the paper separation surface 111 and the transition surface 112 is also easy to process.

[0059] In an exemplary embodiment, the transition surface 112 is a convex arc surface. The connection between the transition surface 112 and the paper separation surface 111 is relatively gentle, making it easy for the paper 5 to enter the paper separation surface 111, and the arc surface is easy to guide the paper 5.

[0060] In an exemplary embodiment, the transition surface 112 is a concave arc surface. The concave shape allows for a larger space in the paper-facing direction, making it easier for the paper 5 to enter the transition surface 112 , and the arc surface facilitates guiding the paper 5 .

[0061] In an exemplary embodiment, the transition surface 112 is an inclined surface, which can guide the paper 5 to the paper separation surface 111.

[0062] In an exemplary embodiment, the transition surface 112 and the paper separation surface 111 are transitioned through a rounded corner 114. The rounded corner 114 makes the connection between the transition surface 112 and the paper separation surface 111 smoother, making it easier for the paper 5 to enter the paper separation surface 111.

[0063] In an exemplary embodiment, the paper separation component 1 includes a paper separation board 11 and a paper separation sheet 12. The paper separation board 11 is provided with a paper separation surface 111 and a transition surface 112. The paper separation board 11 is provided with a paper separation slot 113 opening on the paper separation surface 111. The paper separation sheet 12 is installed in the paper separation slot 113. The paper separation effect is increased by setting the paper separation sheet 12.

[0064] In an exemplary embodiment, a printer includes a frame 2, a paper pickup roller, a first biasing member and the above-mentioned paper separating member 1. The printer also includes a frame 2, a paper pickup roller and a first biasing member. The paper pickup roller is rotatably connected to the frame 2 to pick up paper; the two ends of the first biasing member act on the paper separating member 1 and the frame 2 respectively to apply a force to the paper separating member 1 to move the paper separating member 1 toward the paper pickup roller, so that the paper separating member 1 and the paper pickup roller can clamp the paper 5 to achieve the paper separation effect.

[0065] In an exemplary embodiment, the paperboard storage board 3 is suitable for storing paper 5, and the two ends of the second biasing member 4 act on the paperboard storage board 3 and the frame 2 respectively to apply a force to the paperboard storage board 3 to move the paperboard storage board 3 toward the pickup roller, so that the paperboard storage board 3 and the pickup roller jointly clamp the paper 5, thereby automatically conveying the paper 5 to the waiting position for conveying, facilitating the next printing.

[0066] In an exemplary embodiment, the end of the paper storage board 3 away from the paper pickup roller is hinged to the frame 2, and the second biasing member 4 applies force to the paper storage board 3, and makes the end of the paper storage board 3 close to the paper pickup roller higher than the end away from the paper pickup roller. Rotating the paper top is simpler than vertically sliding the paper top. Rotating the paper top will cause the angle and position of the paper 5 entering the paper separation surface 111 to be inconsistent when there is more paper or less paper, which affects the paper separation effect. This problem will be improved by the structure of the above-mentioned paper separation member 1.

[0067] The above description and embodiments are used to explain the scope of protection of the utility model, but do not constitute a limitation on the scope of protection of the utility model. Based on the enlightenment of the utility model or the above embodiments, modifications, equivalent replacements, or other improvements to the embodiments of the utility model or part of the technical features thereof that can be obtained by ordinary technicians in this field through logical analysis, reasoning, or limited experiments in combination with common knowledge, ordinary technical knowledge in this field and / or existing technology should be included in the scope of protection of the utility model.
