[0035] Reference Figures 1-8 ,

[0036] A paper conveying structure, characterized in that it comprises: a first conveyor 1, a second conveyor 9, and a driving component 2. The first conveyor 1 includes: a pulley 11 and a conveyor belt 12; the second conveyor 9 includes a pressure roller 91. A motor is provided inside the conveying structure, which is connected to the pulley 11 and controls the rotation of the pulley 11. At least two pulleys 11 are provided, and the conveyor belt 12 is wound around the pulley 11. Multiple conveyor belts 12 are provided on the pulley 11, and the conveyor belts 12 are used to contact the lower surface of the paper to be conveyed. The pressure roller 91 is used to contact the upper surface of the paper to be conveyed. The driving component 2 is used to adjust the distance between the first conveyor 1 and the second conveyor 9. The driving component 2 includes a disc 21, a threaded rod 22, and a connecting plate 23. The pressure roller 91 is mounted on a guide rod 4 via a fixing block 3, and the extending direction of the guide rod 4 is the same as the paper conveying direction. The fixed block 3 has a threaded hole, into which a threaded rod 22 is inserted. One end of the threaded rod 22 is fixedly connected to the disc 21, and the other end passes through the connecting plate 23 and is connected to a bolt. The end of the connecting plate 23 away from the fixed block 3 is connected to the pressure roller 91. By rotating the disc 21, the connecting plate 23 rotates, changing the angle between the connecting plate 23 and the conveyor belt 12. Tightening the bolt keeps the angle between the connecting plate 23 and the conveyor belt 12 fixed, thereby adjusting the distance between the pressure roller 91 and the conveyor belt 12. The driving component 2 is also used to drive the pulley 11 to rotate and the pressure roller 91 to rotate. The driving component 2 also includes a motor. The motor is installed inside the conveying structure and is used to connect to the pulley 11 and drive the pulley 11 to rotate. During the conveying process, the lower surface of the paper will contact the conveyor belt 12. Since the pressure roller 91 is above the paper and is in contact with the paper, the pressure roller 91 can rotate in the opposite direction to the paper conveying direction. During the paper conveying process, the lower surface of the paper will contact the conveyor belt 12, and the upper surface of the paper will contact the pressure roller 91. The conveyor belt 12 and the pressure roller 91 work together to effectively ensure the paper conveying. By rotating the disc 21 and fixing it with bolts, the included angle between the connecting plate 23 and the conveyor belt 12 is changed, thereby changing the distance between the conveyor belt 12 and the pressure roller 91, so that some thinner papers can also be conveyed smoothly, thus ensuring subsequent processing.

[0037] Specifically, the second conveyor 9 also includes a mounting frame 92 and a rotating shaft 93. A guide rod 4 is mounted on the mounting frame 92, which is used to fix the conveyor structure. The rotating shaft 93 passes through the pressure roller 91 and is fixedly connected to the connecting plate 23. A bearing 5 is provided between the rotating shaft 93 and the pressure roller 91. The pressure roller 91 has a mounting groove 913 that matches the outer diameter of the bearing 5, and the inner diameter of the bearing 5 matches the outer diameter of the drive shaft. The bearing 5 allows the pressure roller 91 to rotate more smoothly relative to the conveyor belt 12. A sealing cover 6 is provided at the end of the pressure roller 91, and the sealing cover 6 is fixed to the pressure roller 91 to close the mounting groove 913. When the bearing 5 is installed in the sealing groove, dust in the air may enter the bearing 5. Prolonged use may cause the bearing 5 to vibrate during rotation, or even damage the bearing 5. Therefore, a sealing cover 6 is provided at the end of the pressure roller 91 to prevent dust in the air from entering the bearing 5.

[0038] Specifically, at least a first sealing ring 7 and a second sealing ring 8 are provided between the sealing cover 6 and the pressure roller 91. The size of the first sealing ring 7 is larger than the size of the second sealing ring 8. The provision of the first sealing ring 7 and the second sealing ring 8 can prevent dust from entering the bearing 5, further ensuring the service life of the bearing 5.

[0039] Specifically, a first groove 61 is formed on the sealing cover 6, and a second groove 911 is formed on the pressure roller 91. The first groove 61 matches the second groove 911, and both the first groove 61 and the second groove 911 are annular grooves. The size of the first groove 61 and the second groove 911 matches the size of the first sealing ring 7 or the second sealing ring 8. At least two of the first groove 61 and the second groove 911 are provided to accommodate the first sealing ring 7 and the second sealing ring 8. In other embodiments, only one of the first groove 61 and the second groove 911 is provided, and usually only one sealing ring is placed in the first groove 61 and the second groove 911. Such an arrangement makes it difficult to guarantee the long-term use of the bearing 5. Therefore, in this embodiment, at least two of the first groove 61 and the second groove 911 are provided to install the first sealing ring and the second sealing ring 8.

[0040] Specifically, multiple protrusions 9111 are formed in both the first groove 61 and the second groove 911. The protrusions 9111 are hemispherical. When the sealing cover 6 is fixed to the pressure roller 91 by bolts, the protrusions 9111 between the first groove 61 and the second groove 911 can press the first sealing ring 7 and the second sealing ring 8 together and deform the first sealing ring 7 and the second sealing ring 8, thereby improving the sealing effect of the first sealing ring 7 and the second sealing ring 8.

[0041] Specifically, a first extension groove 62 is formed on the sealing cap 6, and a second extension groove 912 is formed on the pressure roller 91. The first extension groove 62 communicates with the first groove 61, and the second extension groove 912 communicates with the second groove 911. After the first sealing ring 7 and the second sealing ring 8 are deformed by compression, part of the deformed area on the first sealing ring 7 or the second sealing ring 8 can enter the first extension groove 62 and the second extension groove 912, further improving the sealing effect of the first sealing ring 7 and the second sealing ring 8.

[0042] Specifically, a protruding ring 63 is formed in the middle of the sealing cover 6. When the sealing cover 6 is fixed to the pressure roller 91, the protruding ring 63 is inserted into the mounting groove 913 and abuts against the outer ring of the bearing 5. An oil injection channel 64 is opened on the end face of the sealing cover 6, and the oil injection channel 64 communicates with the mounting groove 913. After long-term use, the bearing 5 may make abnormal noise due to lack of internal lubricating oil. The oil injection channel 64 allows the operator to inject lubricating oil into the bearing 5. A rotating rod 65 and a rotating plate 66 are provided on the sealing cover 6. The rotating plate 66 rotates around the rotating rod 65 to open and close the oil injection channel 64. Before filling the lubricating chamber 64 with lubricating oil, the operator needs to rotate the rotating plate 66. At this time, the rotating rod 65 will rotate with the rotating plate 66. Then, the rotating rod 65 is removed from the lubricating chamber 64, and the oil can be filled. After the operator fills the lubricating chamber 64 with lubricating oil, the rotating rod 65 can be inserted into the lubricating chamber 64. By rotating the rotating plate 66, the rotating rod 65 can be used to seal the lubricating chamber 64, preventing dust in the air from entering the bearing 5 from the lubricating chamber 64.

[0043] Specifically, the extension direction of the oil injection channel 64 is inclined to the axis of the pressure roller 91.

[0044] In other embodiments, both the first groove 61 and the second groove 911 are provided with annular protrusions. The first sealing ring 7 has multiple first notches formed along its extending direction. The second sealing ring 8 has multiple second notches formed along its extending direction. When the first sealing ring 7 or the second sealing ring 8 is installed in the first groove 61 or the second groove 911, the annular protrusions will engage with the first or second notches, thereby improving the sealing effect of the first sealing ring 7 and the second sealing ring 8.

[0045] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
