Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and more specifically, to a paper receiving platform adjustment mechanism and a paper receiving machine. Background Technology

[0002] Currently, most printing devices on the market, such as laser printers and inkjet printers, are equipped with integrated paper trays or output trays. The main function of a paper tray or output tray is to receive and temporarily store printed paper that has been delivered from the printer's output port, preventing paper from scattering and ensuring the continuous operation of printing jobs.

[0003] However, existing paper trays or output trays have a single function, typically being simple open baskets or trays. When printing multiple documents or performing large-volume jobs with multiple users sharing a printing device, all printed sheets are stacked irregularly in the paper tray. For example, if a 10-page document needs to be printed 5 times, all 50 sheets printed by the printer will be stacked together. Users need to manually sort and organize these 50 sheets; if the number of copies is even greater, it will consume a lot of time and effort for sorting and organizing. This process is not only inefficient but also prone to errors during sorting.

[0004] Therefore, there is an urgent need for a new type of printer auxiliary paper collection device that can collect paper while separating and organizing the paper according to the number of copies based on the printing task (such as different numbers of copies), making it convenient for subsequent manual sorting and easy removal, and improving the efficiency and convenience of large-volume printing operations. Utility Model Content

[0005] To overcome at least one of the defects in the prior art, this utility model provides a paper receiving platform adjustment mechanism that can separate and organize the paper according to the number of copies according to the printing task (such as different copies), which facilitates subsequent manual sorting and easy removal, thereby improving the efficiency and convenience of large-volume printing operations.

[0006] The technical solution adopted by this utility model is as follows: a paper receiving platform adjustment mechanism is provided, including a frame, the front end of the frame is provided with a receiving cavity, a paper receiving platform for receiving paper is provided in the receiving cavity that can be raised and lowered, and the front end of the paper receiving platform extends out of the receiving cavity.

The paper carrier plate is provided with a second motor for driving the drive shaft to rotate and drive the conveyor belt to run.

[0012] Furthermore, the lifting drive assembly includes four sprockets, two chains, and a third motor. Two rotating shafts spaced vertically apart are passed between the left and right side plates of the frame. The four sprockets are respectively connected to the two ends of the two rotating shafts. The two chains are respectively connected to the two sprockets at the left and right ends of the frame. The left and right ends of the lifting tray are respectively connected to the two chains. The third motor is used to drive one of the rotating shafts to rotate.

[0013] In a further improvement, vertically extending optical axis guide rails are provided on the outer walls of the left and right side plates of the frame. Vertically extending clearance slots are respectively opened on the left and right side plates and located on both sides of the accommodating cavity.

[0018] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the embodiments of this application and are not intended to limit the scope of protection of the embodiments of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0019] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "fixed" and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0020] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] See Figures 1-9 As shown in the figure, this application discloses a paper receiving platform adjustment mechanism, including a frame 1. The front end of the frame 1 is provided with a receiving cavity 2. A paper receiving platform for receiving paper is provided in the receiving cavity 2, and the front end of the paper receiving platform extends out of the receiving cavity 2. The paper receiving platform includes a lifting tray 3, a paper carrying plate 4, and a lifting drive assembly for driving the lifting tray 3. The paper carrying plate 4 is slidably disposed on the lifting tray 3, and a conveyor belt for feeding stacked papers from back to front is provided on the paper carrying plate 4. In the above structure, the two side walls of the receiving cavity 2 can play a certain limiting role on both sides of the rear end of the paper receiving platform. In actual application, the paper is stacked on the rear side of the paper receiving platform. After the stacking is completed, the conveyor belt will transport it to the front end of the paper receiving platform for easy removal. In addition, since the paper carrier plate 4 can slide left and right on the lifting tray 3, the paper can be staggered left and right according to the set quantity when stacking. In this way, after all the paper is printed and stacked, multiple corresponding gaps will be formed on both sides of the paper. When sorting, relevant personnel can quickly sort out the set quantity of paper through the corresponding gap positions, effectively improving sorting efficiency.

[0022] In this embodiment, a linear guide rail 5 extending in the left-right direction is provided on the lifting pallet 3. The paper carrier plate 4 is fixed on the slider of the linear guide rail 5. A translation drive assembly for driving the paper carrier plate 4 to move left and right is provided between the lifting pallet 3 and the paper carrier plate 4. As a preferred structure, the translation drive assembly includes a first motor 6 vertically fixed to the lower end face of the lifting pallet 3. The lifting pallet 3 is provided with a mounting through hole 7. A circumferentially rotatable rotating disk 8 is provided in the mounting through hole 7. The middle part of the rotating disk 8 is connected to the output shaft of the first motor 6, and an eccentric wheel 9 is connected to the rotating disk 8. A guide groove 10 extending in the front-back direction is provided on the lower end face of the paper carrier plate 4. The eccentric wheel 9 is slidably engaged in the guide groove 10. The first motor 6 drives the rotation, and under the action of the eccentric wheel 9, it drives the paper carrier plate to move back and forth in the left-right direction to achieve the left-right staggered stacking of the paper.

[0023] In this embodiment, two limiting baffles 11 extending in the front-back direction are provided at intervals on the lower end surface of the paper carrier plate 4, and a guide groove 10 is formed between the two limiting baffles 11. Specifically, in this structure, the limiting baffles 11 include a horizontal base plate and a vertical baffle. The horizontal base plate is fixed to the lower end surface of the paper carrier plate by screws, and the two vertical baffles and the lower bottom surface of the paper carrier plate form a guide groove 10. The horizontal base plate and the vertical baffles are an integral plate structure.

[0024] In addition, the conveyor belt running structure in this embodiment is as follows: a drive shaft 12 and a driven shaft 13 extending along the left and right sides are provided at the front and rear ends of the paper carrier plate 4, and multiple pulleys 14 are provided on the drive shaft 12 and the driven shaft 13, which are spaced apart and correspond one-to-one with each other. A conveyor belt 15 is installed between each pair of pulleys 14 that correspond one-to-one with each other. The upper half of the multiple conveyor belts 15 is located above the paper carrier plate 4 to form a conveyor belt. A second motor 16 is provided on the paper carrier plate 4 to drive the drive shaft 12 to rotate and drive the conveyor belt to run. In this preferred configuration, the rotating shaft 20 at the rear end of the paper carrier plate 4 is the drive shaft 12. The second motor 16 is fixed to the lower surface of the rear end of the paper carrier plate 4. A drive pulley 14 is connected to the output shaft of the second motor 16, and a driven pulley 14 is connected to the drive shaft 12. The drive pulley 14 and the driven pulley 14 are connected by a transmission belt. The rotation of the second motor 16 drives the drive shaft 12 to rotate, thereby driving multiple conveyor belts 15 to rotate in the front-back direction, realizing the translation of the paper. In addition, in this embodiment, the lower half of the multiple conveyor belts 15 is located below the paper carrier plate 4. Due to space constraints, it is preferable that the lower half of the multiple conveyor belts 15 is located below the lifting pallet 3, because in actual use, the left-right movement distance of the paper carrier plate 4 is not large, so the conveyor belts 15 will not interfere with the structure of the lifting pallet 3 during normal operation.

[0025] In another aspect, in this embodiment, the lifting drive assembly includes four sprockets 17, two chains 18, and a third motor 19. Two rotating shafts 20 are arranged vertically and horizontally between the left and right side plates of the frame 1, that is, the two ends of the two rotating shafts 20 protrude outward from the two side walls of the left and right side plates of the frame 1, respectively. The four sprockets 17 are respectively connected to the two ends of the two rotating shafts 20 that protrude outward from the left and right side plates of the frame 1, so that sprocket groups distributed vertically are formed on the left and right sides of the frame 1, respectively. The two chains 18 are respectively connected to the two sprockets 17 at the left and right ends of the frame 1, and the left and right ends of the lifting pallet 3 are respectively connected to the two chains 18. The third motor 19 is used to drive one of the rotating shafts 20 to rotate, thereby driving the two chains 18 to rotate synchronously, and finally realizing the smooth lifting of the lifting pallet 3.

[0026] In this embodiment, further, vertically extending optical axis guide rails 21 are provided on the outer walls of the left and right side plates of the frame 1. Vertically extending clearance slots 22 are respectively provided on the left and right side plates, located on both sides of the accommodating cavity 2. Lifting bases 23 are connected to the left and right ends of the lifting platform 3, respectively. The outer ends of the two lifting bases 23 slide through the two corresponding clearance slots 22, and the outer ends of the two lifting bases 23 protruding from the clearance slots 22 are respectively connected to the sliders of the two optical axis guide rails 21. The optical axis guide rails 21 are designed to effectively ensure the stability of the lifting platform's lifting. The sliders of the two optical axis guide rails 21 are respectively connected to two chains 18. In other embodiments, the two lifting bases 23 can also be directly connected to the two chains 18 through the outer ends protruding from the clearance slots 22, and the lifting platform 3 can be lifted and lowered by the rotation of the chains 18.

[0027] In addition, the first motor 6, the second motor 16, and the third motor 19 involved in this embodiment are all motor components with built-in accelerators, which can better control the output torque.
