Description

Technical Field

[0001] This utility model relates to the field of papermaking equipment technology, and in particular to an adjustable glue application roller. Background Technology

[0002] Papermaking equipment refers to a series of devices encompassed by the industry that produces various machines and equipment for the papermaking industry. It includes machinery for raw material preparation, pulping, papermaking, and the production of finished rolls or sheets, as well as the processing of paper and paperboard. Among these, sizing rollers typically consist of a metal core and a rubber layer covering its surface, which may have specific grooves or textures to meet different sizing requirements.

[0003] When the sizing rollers in traditional papermaking equipment wear out or malfunction, the entire equipment must be shut down and related components disassembled. The maintenance process involves the coordinated disassembly and reassembly of multiple components, which greatly increases the complexity of the operation. Ordinary personnel are unlikely to quickly master the disassembly and assembly operations, which may lead to mechanical damage or component misalignment, thus reducing maintenance efficiency and increasing the maintenance threshold. Summary of the Invention

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the glue roller wears or malfunctions and requires machine shutdown for maintenance, which involves the disassembly and assembly of multiple components and is complicated to operate. To this end, we propose an adjustable glue roller.

[0005] To achieve the above objectives, this application adopts the following technical solution: an adjustable adhesive roller, comprising a bracket, a first frame plate fixedly connected to one side of the bracket, a second frame plate slidably connected to one side of the bracket, a third frame plate fixedly connected to the other side of the bracket, and a fourth frame plate slidably connected to the other side of the bracket. A roller is rotatably connected to one side of each of the first, second, third, and fourth frame plates. A motor is mounted on the other side of the first and second frame plates. One side of the roller is connected to the motor, and a first connecting block is fixedly connected to one side of the roller. Two adhesive roller bodies are installed inside the bracket. Second connecting blocks are fixedly connected to both sides of each adhesive roller body. A first circular groove is formed at both ends of each second connecting block. A first spring is fixedly connected inside the first circular groove. A limit block is fixedly connected to the other end of the first spring. Circular holes are formed at both ends inside the first connecting block. The surface of the limit block is slidably connected to the interior of the circular hole, and a push rod is slidably connected to the interior of the circular hole.

[0006] Preferably, two threaded grooves are provided on the top of both sides of the bracket, and two second circular grooves are provided on the top of the fourth bracket plate and the second bracket plate. A threaded rod is rotatably connected inside the second circular groove, and the surface of the threaded rod is threadedly connected to the inside of the threaded groove.

[0007] Preferably, a limiting plate is fixedly connected to the surface of the limiting block, and the surface of the limiting plate is slidably connected to the interior of the first circular groove.

[0008] Preferably, the top and bottom of the push rod surface are provided with sliding grooves, and the top and bottom of one end of the circular hole are fixedly connected with sliding blocks, the surface of the sliding blocks being slidably connected to the inside of the sliding grooves.

[0009] Preferably, a second spring is slidably connected to the surface of the push rod, one end of the second spring is fixedly connected to one end of the push rod, and the other end of the second spring is fixedly connected to one end inside the circular hole.

[0010] Preferably, a positive magnetic block is installed at one end of the first connecting block, and a negative magnetic block is installed at one end of the second connecting block, wherein the positive magnetic block and the negative magnetic block are magnetically connected.

[0011] Preferably, pull blocks are fixedly connected to both the top and bottom of the second connecting block.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, pressing the push rod causes the limiting block to move out of the circular hole, releasing the engagement between the circular hole and the limiting block, thus disengaging the connection between the glue roller body and the first connecting block. When it is necessary to install the glue roller body and the first connecting block, pressing the limiting block moves it into the first circular groove. Then, the second connecting blocks on both sides of the glue roller body are placed inside the first connecting block. Releasing the pressure on the limiting block causes the first spring to automatically engage with the limiting block and enter the circular hole, thus connecting the glue roller body and the first connecting block. The glue roller body is then installed... Installed inside the bracket, the motor is started, causing the motor to drive the roller to rotate. The rotation of the roller drives the first connecting block to rotate, which in turn drives the second connecting block installed inside the first connecting block to rotate. The rotation of the second connecting block drives the main body of the application roller to rotate. With this setting, when the main body of the application roller wears out due to long-term operation or a sudden failure, the operator can independently separate the roller unit for on-site inspection or component replacement. This design allows maintenance work to be carried out without shutting down the entire equipment or adjusting the support frame. Only the quick-release interface needs to be released to complete the local isolation operation, which significantly reduces the technical intervention threshold and the overall operation and maintenance cost.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Reference Figures 1-5As shown, this utility model provides a technical solution: an adjustable adhesive roller, including a bracket 1, a first mounting plate 2 fixedly connected to one side of the bracket 1, a second mounting plate 3 slidably connected to one side of the bracket 1, a third mounting plate 4 fixedly connected to the other side of the bracket 1, and a fourth mounting plate 5 slidably connected to the other side of the bracket 1. A roller 6 is rotatably connected to one side of the first mounting plate 2, the second mounting plate 3, the third mounting plate 4, and the fourth mounting plate 5. A motor 7 is installed on the other side of the first mounting plate 2 and the second mounting plate 3. The roller 6 is connected to the motor 7. A first connecting block 8 is fixedly connected to one side of the roller 6. The bracket 1 is internally equipped with... There are two application roller bodies 9. A second connecting block 10 is fixedly connected to both sides of each application roller body 9. A first circular groove 11 is formed at both ends of each second connecting block 10. A first spring 12 is fixedly connected inside the first circular groove 11. A limit block 13 is fixedly connected to the other end of the first spring 12. Circular holes 14 are formed at both ends inside the first connecting block 9. The surface of the limit block 13 is slidably connected to the inside of the circular hole 14. A push rod 15 is slidably connected inside the circular hole 14. By pressing the push rod 15, the push rod 15 pushes the limit block 13 out of the circular hole 14. At this time, the circular hole 14 and the limit block 13 are in contact. The engagement between blocks 13 is released, thereby disengaging the connection between the glue roller body 9 and the first connecting block 8. When it is necessary to install the glue roller body 9 and the first connecting block 8, press the limiting block 13 to move it into the first circular groove 11. Then, place the second connecting blocks 10 on both sides of the glue roller body 9 into the first connecting block 8. Then, release the pressure on the limiting block 13. At this time, the first spring 12 automatically abuts against the limiting block 13 and automatically enters the circular hole 14. At this time, the glue roller body 9 and the first connecting block 8 are connected. The glue roller body 9 is installed inside the bracket 1. Start the motor. 7. The motor 7 drives the roller 6 to rotate. The rotation of the roller 6 drives the first connecting block 8 to rotate. The rotation of the first connecting block 8 drives the second connecting block 10 installed inside the first connecting block 8 to rotate. The rotation of the second connecting block 10 drives the body of the glue application roller 9 to rotate. With this setting, when the body of the glue application roller 9 wears out due to long-term operation or sudden failure, the operator can independently separate the roller unit for on-site inspection or component replacement. This design makes maintenance work possible without shutting down the entire equipment or adjusting the support frame. Only the quick-release interface needs to be released to complete the local isolation operation, which significantly reduces the technical intervention threshold and the overall operation and maintenance cost.

[0022] Reference Figure 5As shown in this embodiment: two threaded grooves 16 are opened on the top of both sides of the support 1, and two second circular grooves 17 are opened on the top of the fourth support plate 5 and the second support plate 3. A threaded rod 18 is rotatably connected inside the second circular groove 17. The surface of the threaded rod 18 is threadedly connected to the inside of the threaded groove 16. By turning the threaded rod 18, the threaded rod 18 can drive the second support plate 3 and the fourth support plate 5 to adjust their positions, thereby adjusting the position of the glue roller body 9 to adapt to paper of different thicknesses.

[0023] Reference Figure 3 As shown in this embodiment: the surface of the limiting block 13 is fixedly connected to the limiting plate 19, and the surface of the limiting plate 19 is slidably connected to the inside of the first circular groove 11. By setting the limiting plate 19, the movement position of the limiting block 13 can be restricted, preventing the limiting block 13 from coming out of the inside of the first circular groove 11 due to the elasticity of the first spring 12, and ensuring the stability of the connection between the second connecting block 10 and the first connecting block 8.

[0024] Reference Figure 5 As shown in this embodiment: sliding grooves 20 are provided at the top and bottom of the surface of the push rod 15, and sliding blocks 21 are fixedly connected to the top and bottom of one end of the circular hole 14. The surface of the sliding block 21 is slidably connected to the inside of the sliding groove 20. By allowing the sliding block 21 to slide inside the sliding groove 20, the push rod 15 can be guided, and the push rod 15 can be prevented from shaking when moving.

[0025] Reference Figure 5 As shown in this embodiment: a second spring 22 is slidably connected to the surface of the push rod 15. One end of the second spring 22 is fixedly connected to one end of the push rod 15, and the other end of the second spring 22 is fixedly connected to one end inside the circular hole 14. By setting the second spring 22, the elasticity of the second spring 22 abuts against the push rod 15, which can effectively limit the movement of the push rod 15 and prevent the vibration generated when the equipment is started from causing the push rod 15 to be displaced. At the same time, when the user releases the push rod 15, the push rod 15 can automatically reset.

[0026] Reference Figure 3 and Figure 5 As shown in this embodiment: a positive magnetic block 23 is installed at one end of the first connecting block 8, and a negative magnetic block 24 is installed at one end of the second connecting block 10. The positive magnetic block 23 and the negative magnetic block 24 are magnetically connected. By setting the positive magnetic block 23 and the negative magnetic block 24, the second connecting block 10 can be automatically positioned when it is installed inside the first connecting block 8, without the need for manual alignment, which greatly improves the installation efficiency. At the same time, the magnetic connection method also makes the second connecting block 10 more securely installed inside the first connecting block 8.

[0027] Reference Figure 3As shown in this embodiment: the top and bottom of the second connecting block 10 are fixedly connected with pull blocks 25. By setting pull blocks 25, the user has more leverage points when disassembling and assembling the glue roller body 9, making it easier for the user to operate.

[0028] Working principle: By pressing the push rod 15, the push rod 15 pushes the limiting block 13 out of the circular hole 14. At this time, the engagement between the circular hole 14 and the limiting block 13 is released, thereby disconnecting the connection between the glue roller body 9 and the first connecting block 8. When it is necessary to install the glue roller body 9 and the first connecting block 8, press the limiting block 13 to move it into the first circular groove 11. Then, place the second connecting blocks 10 on both sides of the glue roller body 9 into the first connecting block 8. Then release the pressure on the limiting block 13. At this time, the first spring 12 automatically abuts against the limiting block 13 and automatically enters the circular hole 14. At this time, the glue roller body 9 and the first connecting block 8 are connected. Connecting block 8 forms a connection, and the main body 9 of the application roller is installed inside the bracket 1. Starting motor 7 causes the roller 6 to rotate, which in turn rotates the first connecting block 8. The rotation of the first connecting block 8 then rotates the second connecting block 10 installed inside it, which in turn rotates the application roller body 9. This design allows operators to independently separate the roller unit for on-site repair or component replacement when the application roller body 9 experiences wear or sudden failure due to long-term operation. This design eliminates the need for complete equipment shutdown or support frame adjustments during maintenance; only the quick-release interface needs to be disconnected for partial isolation, significantly reducing technical intervention. Threshold and comprehensive operation and maintenance costs: By turning the threaded rod 18, the threaded rod 18 can drive the second frame plate 3 and the fourth frame plate 5 to adjust their positions, thereby adjusting the position of the glue roller body 9 to adapt to paper of different thicknesses. By setting the limiting plate 19, the movement position of the limiting block 13 can be restricted, preventing the limiting block 13 from dislodging from the inside of the first circular groove 11 due to the elasticity of the first spring 12, ensuring the stability of the connection between the second connecting block 10 and the first connecting block 8. By allowing the sliding block 21 to slide inside the sliding groove 20, the push rod 15 can be guided, preventing the push rod 15 from shaking during movement. By setting the second spring 22, the first The elasticity of the two springs 22 abuts against the push rod 15, which can effectively limit the movement of the push rod 15 and prevent the vibration generated when the equipment is started from causing the push rod 15 to be displaced. At the same time, when the user releases the push rod 15, the push rod 15 can automatically reset. By setting the positive magnetic block 23 and the negative magnetic block 24, the second connecting block 10 can be automatically positioned when it is installed into the first connecting block 8, eliminating the need for manual alignment and greatly improving the installation efficiency. At the same time, the magnetic connection method also makes the second connecting block 10 more securely installed inside the first connecting block 8. The pull block 25 provides the user with a more force point when disassembling and assembling the glue roller body 9, making it easier for the user to operate.
