Description

Technical Field

[0001] This invention relates to the field of paper conveying technology, specifically to a rotary turning mechanism for paper conveying rollers. Background Technology

[0002] In the process of paper processing or printing, paper needs to be transported from one position to another by rolling action. The friction generated by the rotation of the conveyor rollers drives the paper, thereby achieving continuous paper transport. Before use, the conveyor rollers need to be machined to ensure better transport.

[0003] Prior art 1 (Chinese Patent No. CN116689797B, published on 2023-10-13) discloses a turning device for processing submerged rolls. This invention relates to the field of turning equipment technology. The bottom of the turning device is configured as a drive base, and the bottom of the drive base is provided with a base. Support frames are installed on both sides of the top surface of the base. A lead screw is movably installed between the support frames. A slider is sleeved on the outer ring of the lead screw. A milling cutter assembly is installed at the front end of the slider. The milling cutter assembly includes a positioning wheel, a protective buckle, and a milling cutter. A protective buckle is installed between the positioning wheel and the milling cutter. A spring-loaded rod is inserted inside the protective buckle to effectively guide the milling cutter during turning. A protective buckle is installed behind the positioning wheel. When the protective buckle reaches the edge of the submerged roll, the internal spring-loaded rod pushes outward, causing the protective buckle and the milling cutter assembly to disconnect, preventing the milling cutter from continuing to spin freely or causing a collision. This protects the milling cutter when turning the end of the submerged roll, reducing the loss of the turning device.

[0004] There is also prior art 2 (Chinese Patent Publication No.: CN115229240A, Publication Date: 2022-10-25) which discloses a printing plate roller turning device, comprising: a frame; a frame; a three-jaw chuck rotatably connected to one end of the frame, capable of rotating under the drive of a drive mechanism and fixing one end of the printing plate roller between the three-jaw chuck; a moving mechanism disposed at the end of the frame away from the three-jaw chuck, the moving mechanism being movable on the frame; a drilling device comprising a drill bit whose axis is coaxial with the axis of the printing plate roller, the drill bit being capable of drilling holes in the printing plate roller under the drive of the moving mechanism; and a fixing mechanism for fixing the drill bit during installation. This device effectively reduces the loosening of the drill bit during the drilling process of the printing plate roller.

[0005] While existing technologies 1 and 2 can perform turning operations on conveyor rollers, they mostly cannot provide auxiliary fixing and adjustment on the sides of the roller body when fixing the conveyor roller. As a result, the roller is prone to falling off during the turning operation, which affects the subsequent turning effect.

[0006] Therefore, we propose a rotary turning mechanism for paper conveying rollers to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide a rotary turning mechanism for paper conveying rollers, in order to solve the problem mentioned in the background art that most of the current market methods for fixing conveying rollers cannot provide auxiliary fixing and adjustment on the sides of the roller body, and the roller is prone to falling off during turning operations, thereby affecting the subsequent turning effect.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a rotary turning mechanism for paper conveying rollers, comprising a base, an electric slide rail fixedly connected to the upper surface of the base, a tool holder mounted on the electric slide rail, a fixed frame fixedly connected to the side of the upper surface of the base, and a movable frame provided on the other side of the base. The fixed frame is fixedly connected to the inner side of the fixed frame, and the compression air bladder is fixedly connected to the inner side of the fixed frame. A fixed column is nested on the end side of the fixed frame, and an expansion mechanism that can assist in fixing the conveying roller is provided between the end side of the fixed column and the compression air bladder. An auxiliary plate is fixedly connected to the inner side of the movable frame, and a limit groove is provided on the auxiliary plate. A movable rod is nested inside the limit groove, and a limit plate is fixedly connected to the outer side of the movable rod. An adjustment mechanism is provided between the inner side of the movable rod and the inside of the auxiliary plate to adjust the position of the limit plate.

[0009] Preferably, the expansion mechanism includes a pressing plate, which is fixedly connected to the outside of the compression airbag. A groove is formed at the center of the pressing plate, and a slider is nested inside the groove. An auxiliary rod is fixedly connected to the end of the slider, and one end of the auxiliary rod extends into the inside of the compression airbag. A baffle is fixedly connected to the outside of the auxiliary rod. A movable piece is fixedly connected to the end of the auxiliary rod, and a first spring is fixedly connected between the inner side of the movable piece and the compression airbag. A connecting rod is nested at the center of the pressing plate, and the connecting rod is fixedly connected to the end of a fixed column. An expansion airbag is fixedly connected to the outside of the fixed column.

[0010] Preferably, the inflatable airbag and the compression airbag are interconnected, and the pressing plate forms a sliding structure with the fixed column and the fixed frame.

[0011] Preferably, the slider forms a sliding structure with the connecting rod and the sliding groove, the diameter of the moving piece is larger than the diameter of the baffle, and the moving piece forms an elastic mechanism with the first spring and the compression airbag.

[0012] Preferably, the adjustment mechanism includes a first threaded rod, which is nested at the center of the auxiliary disk. A turntable is threadedly connected to the outer side of the first threaded rod, and the turntable is disposed inside the auxiliary disk. A pressing plate is fixedly connected to the outer end of the first threaded rod, and a second spring is fixedly connected between the inner side of the pressing plate and the outer surface of the auxiliary disk. An adjustment groove is provided on the turntable, and the inner end of the moving rod is nested inside the adjustment groove.

[0013] Preferably, the pressing plate forms an elastic structure with the auxiliary plate via the second spring, the first threaded rod forms a sliding structure with the pressing plate and the auxiliary plate, and the turntable forms a rotating structure with the first threaded rod.

[0014] Preferably, the adjusting groove is arranged in an arc-shaped circular array, and the moving rod forms a sliding structure with the limiting groove through the adjusting groove.

[0015] Preferably, a linkage rod is fixedly connected to the outer end of the limiting plate, and a connecting plate is fixedly connected to the end side of the linkage rod. One end of the connecting plate is nested and connected to the inner upper surface of the movable frame. A shrink plate is nested and connected to the other side of the connecting plate. At the same time, the outer end of the shrink plate is nested and connected to the inner side of the fixed frame. A shrink rod is fixedly connected to the lower surface of both the connecting plate and the shrink plate, and a pull-out dust removal plate is fixedly connected to the lower end of the shrink rod.

[0016] Preferably, a placement plate is fixedly connected to the inner side of the fixing frame, and a striking rod is nested inside the placement plate. A third spring is fixedly connected between the lower end of the striking rod and the lower surface of the placement plate, and a magnetic block is fixedly connected between the lower end of the striking rod and the lower surface of the placement plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are: The user can connect the conveyor roller to the outside of the fixed column. At this time, the user can manually push the conveyor roller to move the fixed column to the inside of the fixed frame. This causes the fixed column to squeeze the pressing plate, and the pressing plate to squeeze the air bladder. At this time, the gas inside the air bladder can be transported to the inside of the expansion air bladder through the exhaust channel, causing the expansion air bladder to expand. The expanded air bladder can fit against the inside of the end side of the conveyor roller, thereby further improving the stability of the connection between the conveyor roller and the fixed column, thus allowing for better subsequent turning processing. During the movement of the fixed column, the docking rod fixedly installed on the end of the fixed column will dock with the inside of the pressing plate. At this time, the docking rod will abut against and push the slider, so that the slider moves along the inside of the groove. When the slider moves, it will simultaneously drive the baffle to move backward through the auxiliary rod. At this time, the baffle does not block the exhaust port of the compression airbag. When the outside of the fixed column is not docking, the moving plate will drive the baffle to reset under the elastic force of the first spring, thereby blocking the exhaust port of the compression airbag. At the same time, it will push the docking rod outward to further reset the fixed column, which will facilitate subsequent docking operations. After the initial docking of the conveyor rollers is completed, the user can adjust the moving frame to move it. At this time, the pressing plate contacts the other side of the conveyor roller. At the same time, the pressing plate is under pressure, which will drive the first threaded rod to move along the outside of the auxiliary plate. Under the action of the threaded connection, the turntable will rotate. When the turntable rotates, the adjustment groove set inside it will abut against the moving rod, causing the moving rod to move. At this time, the moving rod can move stably under the limiting action of the limiting groove, and provide auxiliary limiting for the other end of the conveyor roller, thereby improving the stability of subsequent turning. During the movement of the limit plate, the connecting plate will move downwards in sync. At this time, the connecting plate can be driven to move the pull-out cleaning plate downwards in sync through the retraction rod until the pull-out cleaning plate moves downwards and comes into contact with the surface of the conveyor roller. The pull-out cleaning plate can clean the impurities generated during the turning of the conveyor roller surface, thereby reducing the impact of impurities on subsequent turning. The shrink plate moves synchronously under the action of the limiting plate. When the shrink plate is reset, the lower end of the shrink plate does not contact the striking rod. The striking rod moves upward and resets under the magnetic force of the two sets of magnetic blocks, thereby striking the shrink plate and causing it to vibrate. The force of the shrink plate vibration is transmitted to the pull-out cleaning plate, thereby shaking off the impurities accumulated on the pull-out cleaning plate. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: As Figure 1 , Figures 3-6 The present invention provides the following technical solution: a rotary turning mechanism for paper conveying rollers, which discloses an expansion mechanism to improve the stability of the conveying roller fixation. The base 1 has an electric slide rail 6 fixedly connected to its upper surface, and a knife holder 7 is installed on the electric slide rail 6. A fixed frame 2 is fixedly connected to the side of the upper surface of the base 1, and a movable frame 3 is provided on the other side of the base 1. A fixed frame 5 is fixedly connected to the inner side of the fixed frame 2, and a compression air bladder 18 is fixedly connected to the inner side of the fixed frame 5. A fixed column 16 is nested on the end side of the fixed frame 5, and an expansion mechanism for auxiliary fixing of the conveyor roller is provided between the end side of the fixed column 16 and the compression air bladder 18. The expansion mechanism includes a pressing plate 19, which is fixedly connected to the outside of the compression airbag 18. A groove 24 is formed at the center of the pressing plate 19, and a slider 25 is nested inside the groove 24. An auxiliary rod 26 is fixedly connected to one end of the slider 25, and one end of the auxiliary rod 26 extends into the compression airbag 18. A baffle 21 is fixedly connected to the outside of the auxiliary rod 26, and a movable piece 22 is fixedly connected to the end of the auxiliary rod 26. A first spring 2 is fixedly connected between the inner side of the movable piece 22 and the compression airbag 18. 3. A connecting rod 20 is nested at the center of the pressing plate 19, and the connecting rod 20 is fixedly connected to the end side of the fixing column 16. An expansion airbag 17 is fixedly connected to the outside of the fixing column 16. The expansion airbag 17 and the compression airbag 18 are interconnected. The pressing plate 19 forms a sliding structure with the fixing frame 5 through the fixing column 16. The slider 25 forms a sliding structure with the sliding groove 24 through the connecting rod 20. The diameter of the moving piece 22 is larger than the diameter of the baffle 21, and the moving piece 22 forms an elastic mechanism with the compression airbag 18 through the first spring 23.

[0022] The user can connect the conveyor roller to the outside of the fixed column 16. At this time, the user can manually push the conveyor roller to move the fixed column 16 to the inside of the fixed frame 5. This causes the fixed column 16 to press the pressing plate 19 and press the compression airbag 18. At this time, the gas inside the compression airbag 18 can be transported to the inside of the expansion airbag 17 through the exhaust channel, causing the expansion airbag 17 to expand. The expanded expansion airbag 17 can fit against the inside of the end side of the conveyor roller, thereby further improving the stability of the connection between the conveyor roller and the fixed column 16, thus allowing for better subsequent turning processing. During the movement of the fixed column 16, the docking rod 20 fixedly installed on the end of the fixed column 16 will dock with the inside of the pressing plate 19. At this time, the docking rod 20 will abut against and push the slider 25, thereby causing the slider 25 to move along the inside of the slide groove 24. When the slider 25 moves, it will simultaneously drive the baffle 21 to move backward through the auxiliary rod 26. At this time, the baffle 21 will not block the exhaust port of the compression airbag 18. When the outside of the fixed column 16 is not docking, the moving plate 22 will drive the baffle 21 to reset under the elastic force of the first spring 23, thereby blocking the exhaust port of the compression airbag 18. At the same time, it will push the docking rod 20 outward, further resetting the fixed column 16 to facilitate subsequent docking operations.

An auxiliary plate 4 is fixedly connected to the inner side of the movable frame 3, and a limit groove 29 is provided on the auxiliary plate 4. A movable rod 28 is nested inside the limit groove 29. Meanwhile, a limit plate 27 is fixedly connected to the outer side of the movable rod 28. An adjustment mechanism is provided between the inner side of the movable rod 28 and the inside of the auxiliary plate 4 to adjust the position of the limit plate 27. The adjustment mechanism includes a first threaded rod 12, which is nested at the center of the auxiliary disk 4. A turntable 15 is threadedly connected to the outer side of the first threaded rod 12 and is located inside the auxiliary disk 4. A pressing plate 14 is fixedly connected to the outer end of the first threaded rod 12, and a second spring 30 is fixedly connected between the inner side of the pressing plate 14 and the outer surface of the auxiliary disk 4. An adjustment groove 31 is provided on the turntable 15. The inner end of the moving rod 28 is nested inside the adjustment groove 31. The pressing plate 14 and the auxiliary disk 4 form an elastic structure through the second spring 30. The first threaded rod 12 and the auxiliary disk 4 form a sliding structure through the pressing plate 14. The turntable 15 forms a rotating structure through the first threaded rod 12. The adjustment groove 31 is arranged in an arc-shaped annular array. The moving rod 28 forms a sliding structure through the adjustment groove 31 and the limiting groove 29.

[0024] After the initial docking of the conveyor rollers is completed, the user can adjust the movable frame 3 to move it. At this time, the pressing plate 14 contacts the other side of the conveyor roller. Simultaneously, the pressing plate 14 is subjected to pressure, which will drive the first threaded rod 12 to move along the outside of the auxiliary plate 4. Under the action of the threaded connection, the turntable 15 will rotate. When the turntable 15 rotates, the adjustment groove 31 set inside it will abut against the moving rod 28, causing the moving rod 28 to move. At this time, the moving rod 28 can move stably under the limiting action of the limiting groove 29, and provide auxiliary limiting for the other end of the conveyor roller, thereby improving the stability of subsequent turning.

[0025] Example 3: Figure 1 , Figure 2 , Figure 9 and Figure 10 The present invention provides the following technical solution: a rotary turning mechanism for paper conveying rollers, which discloses a pull-out dust removal plate 10, which can be used to clean dust: A linkage rod 32 is fixedly connected to the outer end of the limiting plate 27, and a connecting plate 8 is fixedly connected to the end side of the linkage rod 32. One end of the connecting plate 8 is nested and connected to the inner upper surface of the movable frame 3. A shrink plate 9 is nested and connected to the other side of the connecting plate 8.

A pull-out dust removal plate 10 is fixedly connected to the lower end of the shrink rod 33. A placement plate 35 is fixedly connected to the inner side of the fixed frame 2. A striking rod 34 is nested and connected inside the placement plate 35.

A magnetic block 11 is fixedly connected between the lower end of the striking rod 34 and the lower surface of the placement plate 35.

[0026] During the movement of the limiting plate 27, the connecting plate 8 will move downwards synchronously. At this time, the connecting plate 8 can move the pull-out cleaning plate 10 downwards synchronously through the shrinking rod 33 until the pull-out cleaning plate 10 moves downwards and comes into contact with the surface of the conveyor roller. The pull-out cleaning plate 10 can clean the impurities generated by the turning of the conveyor roller surface, thereby reducing the impact of impurities on subsequent turning. The shrinking plate 9 will move synchronously under the action of the limiting plate 27. When the shrinking plate 9 is reset, the lower end of the shrinking plate 9 will not contact the striking rod 34. The striking rod 34 will move upwards and reset under the magnetic force of the two sets of magnetic blocks 11, thereby striking the shrinking plate 9 and causing the shrinking plate 9 to vibrate. At this time, the force of the vibration of the shrinking plate 9 will be transmitted to the pull-out cleaning plate 10, thereby shaking off the impurities accumulated on the pull-out cleaning plate 10.
