Description

Technical Field

[0001] This utility model relates to the field of paper receiving machine technology, specifically to a quick-change mechanism for upper and lower paper receiving of a paper receiving machine. Background Technology

[0002] The paper receiving machine includes an inlet, a bottom outlet, and a receiving plate. After printing, the paper is conveyed to the inlet, then falls onto the receiving plate after passing through the bottom outlet for stacking and collection. Once the paper is full, the printer needs to be stopped, and it can only be restarted after the staff transfers the paper from the receiving plate. However, this greatly reduces the printer's working efficiency. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a quick-change mechanism for upper and lower paper collection in a paper receiving machine, which can continuously stack and collect paper without stopping the printer.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a quick-change mechanism for upper and lower paper collection in a paper receiving machine, comprising a frame, an inlet, and a lower outlet. The top of the frame has an upper outlet, and a drive assembly is provided on the frame. A movable plate is provided at the inlet, which divides the inlet into an upper inlet and a lower inlet. The upper inlet and the upper outlet are connected by an upper channel, and the lower inlet and the lower outlet are connected by a lower channel.

[0005] When the drive component is in the first working state, the upper feed port is closed and the lower feed port is open; when the drive component is in the second working state, the upper feed port is open and the lower feed port is closed.

[0006] Furthermore, the driving assembly includes a fixed frame, an electromagnet, an iron rod, a spring, a first transmission rod, and a second transmission rod. The fixed frame is fixedly mounted on the frame and has a guide hole. The electromagnet is fixedly mounted on the inner wall of the fixed frame. The iron rod is disposed in the guide hole and slidably connected to the inner wall of the guide hole. The two ends of the spring are fixedly connected to the iron rod and the fixed frame, respectively. The spring causes the iron rod to tend to move away from the fixed frame. The first end of the first transmission rod is fixedly connected to the iron rod, the second end of the first transmission rod is hinged to the first end of the second transmission rod, and the second end of the second transmission rod is hinged to the movable plate.

[0007] Furthermore, the movable plate has a V-shaped structure, with the pointed corner of the movable plate facing the opening of the feed inlet.

[0008] Furthermore, a transmission assembly is provided at the bottom of the upper channel. The transmission assembly includes a transmission shaft and a motor. Multiple transmission shafts are arranged at intervals, and adjacent transmission shafts are connected by a synchronous belt. Multiple friction rollers are fixedly installed on the transmission shafts, and the motor is used to control the rotation of one of the transmission shafts.

[0009] Furthermore, a flap is provided at the top of the upper channel, the first end of the flap is rotatably connected to the frame, the second end of the flap is snapped into the frame, and multiple universal ball bearings are fixedly installed at the bottom of the flap.

[0010] The beneficial effects of this utility model: This utility model provides a quick-change mechanism for upper and lower paper collection in a paper receiving machine. When the drive component is in the first working state, the paper discharged from the printer passes through the lower feed port, the lower channel, and the lower discharge port in sequence, and finally stacks on the receiving plate. When the paper on the receiving plate is full, the drive component switches to the second working state. At this time, the paper discharged from the printer passes through the upper feed port, the upper channel, and the upper discharge port in sequence, and finally stacks at the upper discharge port. Therefore, this utility model can continuously collect and stack paper without stopping the printer. Attached Figure Description

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] In this application, unless otherwise expressly specified and limited, the terms "connection" and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] In the description of this application, it should be understood that the terms "longitudinal", "horizontal", "level", "top", "bottom", "upper", "lower", "inner" and "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0020] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly defined.

[0021] like Figure 1-4 As shown, this utility model provides a quick-change mechanism for upper and lower paper receiving of a receiving machine, which is used in conjunction with a printer. It includes a frame 10, a feeding port and a lower discharging port. The above contents are all prior art, and the specific structure will not be described in detail here.

[0022] The top of the frame 10 has an upper discharge port 11, and a drive assembly 20 is provided on the frame 10. A movable plate 30 is provided at the inlet, which divides the inlet into an upper inlet 12 and a lower inlet 13. The upper inlet 12 and the upper discharge port 11 are connected by an upper channel, and the lower inlet 13 and the lower discharge port are connected by a lower channel.

[0023] The drive assembly 20 is used to control the swing of the movable plate 30. When the drive assembly 20 is in the first working state, the movable plate 30 is in contact with the top of the feed inlet, at which time the upper feed inlet 12 is closed and the lower feed inlet 13 is open. When the drive assembly 20 is in the second working state, the movable plate 30 is in contact with the bottom of the feed inlet, at which time the upper feed inlet 12 is open and closed.

[0024] In the initial state, the drive component 20 is in the first working state, the movable plate 30 is in contact with the top of the feed port, and the paper discharged by the printer will pass through the lower feed port 13, the lower channel and the lower output port in sequence, and finally be stacked on the receiving plate.

[0025] When the paper on the receiving plate is full, the drive assembly 20 controls the movable plate 30 to swing, and the movable plate 30 contacts the bottom of the feed inlet. At this time, the drive assembly 20 switches to the second working state. The paper discharged from the printer will pass through the upper feed inlet 12, the upper channel, and the upper output outlet 11 in sequence, and finally stack at the upper output outlet 11. Therefore, this invention can continuously stack and collect paper without stopping the printer, thus improving the printer's working efficiency.

[0026] In one embodiment, the drive assembly 20 includes a fixed frame 21, an electromagnet 22, an iron rod 23, a spring 24, a first transmission rod 25, and a second transmission rod 26. The fixed frame 21 is fixedly mounted on the frame 10 and has a guide hole communicating with its interior. The electromagnet 22 is fixedly mounted on the inner wall of the fixed frame 21 and is electrically connected to the printer's control system. The iron rod 23 is disposed within the guide hole and slidably connected to the inner wall of the guide hole. The spring 24 is sleeved on the iron rod 23, with both ends of the spring 24 fixedly connected to the iron rod 23 and the fixed frame 21, respectively, causing the iron rod 23 to tend to move away from the fixed frame 21. The first end of the first transmission rod 25 is fixedly connected to the iron rod 23, the second end of the first transmission rod 25 is hinged to the first end of the second transmission rod 26, and the second end of the second transmission rod 26 is hinged to the movable plate 30.

[0027] When the drive assembly 20 is in the first working state, the printer's control system controls the electromagnet 22 to be de-energized. Under the action of the spring 24, the iron rod 23 pushes the first transmission rod 25 outward, and the second transmission rod 26 pushes the movable plate 30 upward. At this time, the movable plate 30 will contact the top of the feed port.

[0028] When the drive assembly 20 is in the second working state, the printer's control system controls the electromagnet 22 to be energized, and the iron rod 23 will be attracted to the electromagnet 22. At this time, the iron rod 23 pulls the first transmission rod 25 inward, and the second transmission rod 26 pulls the movable plate 30 downward. At this time, the movable plate 30 will contact the bottom of the feed port.

[0029] This drive component 20 has a simple structure and is easy to manufacture and control.

[0030] In one embodiment, the movable plate 30 has a V-shaped structure, with the pointed corner of the movable plate 30 facing the opening of the feed inlet.

[0031] The tip of the V-shaped movable plate 30 has a guiding function, so that when the drive assembly 20 is in the second working state, the paper discharged by the printer will move smoothly to the top of the movable plate 30, and thus smoothly move to the upper channel and the upper discharge port 11.

[0032] In one embodiment, a transmission assembly is provided at the bottom of the upper channel, the transmission assembly including a drive shaft 41 and a motor. Multiple drive shafts 41 are arranged at intervals, and adjacent drive shafts 41 are connected by a synchronous belt. Multiple friction rollers 42 are fixedly mounted on the drive shafts 41. The motor is used to control the rotation of one of the drive shafts 41, and the motor is electrically connected to the printer's control system.

[0033] When the drive assembly 20 is in the second working state, the printer's control system controls the motor to start, and the motor will drive the corresponding drive shaft 41 to rotate. Under the action of the synchronous belt, multiple drive shafts 41 will rotate synchronously, and the friction roller 42 will convey the paper in the upper channel to the upper discharge port 11.

[0034] In one embodiment, a flap 50 is provided at the top of the upper channel. The first end of the flap 50 is rotatably connected to the frame 10, and the second end of the flap 50 is snapped into the frame 10. Multiple universal ball bearings 51 are fixedly installed at the bottom of the flap 50.

[0035] The universal ball bearings 51 on the flip plate 50 work together with the transmission components to press the paper in the upper channel. When the motor starts, the paper in the upper channel will be stably transmitted to the upper discharge port 11, reducing paper shaking and making the paper conveying process more stable.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
