Description

Technical Field

[0001] This utility model relates to the field of calender roll cleaning technology, and in particular to a cleaning device for calender rolls. Background Technology

[0002] Calendering is one of the important basic processes in polymer material processing. During calendering, due to the high temperature of the raw material, cold water needs to be introduced into the calendering roll for cooling. However, after a long period of time, tap water will be introduced, which will form an uneven layer of scale, requiring frequent cleaning. Therefore, cleaning equipment is needed.

[0003] The patent with announcement number CN218691849U discloses a calendering roll cleaning device with good bonding effect, including a box body. A fixing plate is fixedly connected to the right side of the box body near the bottom. A support base is fixedly connected to the top of the fixing plate near the right side. A motor is fixedly connected to the top of the support base. A cleaning rod is fixedly connected to the power output shaft of the motor.

[0004] In the above case, the calendering roll is fixed by the pre-drilled holes inside the box. Then, by clicking, the cleaning rod inside the calendering roll and the two cleaning rollers above and below the calendering roll clean the inside and outside of the calendering roll. However, because the holes inside the box are fixed, the device can only clean calendering rolls of one coarseness, which reduces the applicability of the device. In addition, the device is not convenient for cleaning and replacing the cleaning rod and cleaning rollers. As a result, the cleaning effect will decrease after the device has been working for a long time, which reduces the practicality of the device.

[0005] Therefore, this invention provides a cleaning device for calender rolls to meet the requirements. Utility Model Content

[0024] Please see Figures 1-4 This utility model provides a cleaning device for calender rolls, including a main body 1 and a calender roll body 17. Fixed seats 2 are fixedly connected to both ends of the top of the main body 1. Rotary seats 3 are fixedly connected to both ends of the inner side of the fixed seats 2. A rotating ring 4 is rotatably connected to the top of the two rotating seats 3. The calender roll body 17 is located inside the two rotating rings 4. Several cylinders 5 are fixedly connected to the inner side of the rotating rings 4. Clamping blocks 6 are fixedly connected to the output ends of the cylinders 5. Gear rings 7 are fixedly connected to the outer side of the rotating rings 4. A motor 8 is fixedly connected to the outer side of one of the fixed seats 2, and a drive gear 9 is fixedly connected to its output end. The drive gear 9 meshes with the corresponding gear ring 7. Support legs are fixedly connected to all four sides of the bottom of the main body 1. A locking block is fixedly connected to the top of the inner side of the fixed seat 2, located above the rotating ring 4. The locking block is in close contact with the upper half of the outer side of the rotating ring 4 and is used to lock the rotating ring 4. There are three cylinders 5 inside the same rotating ring 4. Clamping blocks 6 are distributed in a ring on the inner side of the rotating ring 4.

[0025] Place the calender roll body 17 inside the two rotating rings 4, start all the cylinders 5, and push the clamping blocks 6 closer to the calender roll body 17 until they clamp both ends of the calender roll body 17.

[0026] Please see Figures 1-4Inside the main body 1, sliders 10 are slidably connected around the perimeter between two fixed seats 2. The tops of the two sliders 10 located on one side of the two fixed seats 2 are fixedly connected to the same insertion seat 11, and the bottoms are fixedly connected to the same drive seat 15. Sliding strips 12 are slidably connected to the ends of the two insertion seats 11 closest to each other. A bidirectional screw 14 is rotatably connected to the bottom of the main body 1. Two drive seats 15 are threaded to the two ends of the bidirectional screw 14. A limiting seat 18 is fixedly connected to the top of the main body 1 on one side of the two fixed seats 2. A locking seat 19 is slidably connected to the top of the limiting seat 18. A second fixing pin 20 is slidably connected to the inner side of the locking seat 19. A cleaning rod 21 is locked to the inner side of the locking seat 19 via the second fixing pin 20. The sliding strips 12 and the cleaning rod 21 are used to clean the calender roll body 17. A second motor 16 is fixedly connected to the bottom, and its output end is fixedly connected to a bidirectional screw 14. Brushes are fixedly connected to the adjacent sides of the two sliding inserts 12, and they are in close contact with both sides of the calender roll body 17. A first fixing pin 13 for fixing the sliding inserts 12 is slidably connected inside the insertion seat 11. A side rod is fixedly connected to the top of the main body 1 on the side away from the snap-fit ​​seat 19. The end of the cleaning rod 21 away from the snap-fit ​​seat 19 passes through the interior of the calender roll body 17 and is slidably connected to the inside of the side rod. A cleaning brush is fixedly connected to the outside of the cleaning rod 21 inside the calender roll body 17. A snap-fit ​​block 22 is fixedly connected to the outside of the cleaning rod 21 on the side away from the calender roll body 17 of the snap-fit ​​seat 19. Side blocks 23 are fixedly connected to the upper and lower ends of the snap-fit ​​seat 19 near the snap-fit ​​block 22. The snap-fit ​​block 22 is snapped between the two side blocks 23.

[0027] Then, start motor 16 to drive the bidirectional screw 14 to rotate, which in turn drives the two drive seats 15, the insertion seat 11, and the sliding insert 12 to move closer to the calender roll body 17 until the brush is close to the outside of the calender roll body 17. The cleaning rod 21 is then passed through the inside of the calender roll body 17 and inserted into the side rod. The sliding locking seat 19 is slid to the outside of the cleaning rod 21, so that the locking block 22 is embedded in the two side blocks 23. Then, start motor 8 to drive the rotating ring 4 to rotate through the drive gear 9 and the gear ring 7, which in turn rotates the calender roll body 17. The cleaning brush and the brush clean the inside and outside of the calender roll body 17.

[0028] The cylinder 5 can drive the clamping block 6 to move closer to the calender roll body 17, clamping the calender roll bodies 17 of different thicknesses to achieve a stable and reliable clamping effect. When the bidirectional screw 14 rotates, the threads on both sides will drive the two drive seats 15 to move in opposite directions, which can precisely adjust the distance between the two sliding strips 12, thereby achieving close-fitting cleaning of calender rolls of different thicknesses. This makes the device successfully realize the stable clamping and close-fitting cleaning function of calender rolls of different thicknesses, which not only improves the applicability and flexibility of the device, but also provides users with a more convenient and efficient cleaning experience.

[0029] The insertion seat 11 serves as a support and connecting component for the sliding strip 12. Its internal design includes a groove that matches the sliding strip 12, allowing the sliding strip 12 to be easily inserted and fixed within it. The first fixing pin 13 is used to further lock the position of the sliding strip 12, preventing it from sliding or falling off due to force during the cleaning process. This design not only simplifies the disassembly and assembly process of the sliding strip 12 but also improves its stability and durability. The combination design of the snap-fit ​​seat 19 and the second fixing pin 20 not only improves the disassembly and assembly efficiency of the cleaning rod 21 but also ensures the stability and consistency of its cleaning effect. When the cleaning rod 21 slides into the snap-fit ​​seat 19 and is fixed, the locking block 22 will be precisely engaged between the side blocks 23, forming a stable fixing structure. This not only prevents the cleaning rod 21 from rotating due to force when the calender roll body 17 rotates but also improves its overall stability and durability.

[0030] The working principle and usage process of this utility model are as follows: Place the calender roll body 17 inside the two rotating rings 4, start all the cylinders 5, push the clamping blocks 6 closer to the calender roll body 17 until they clamp both ends of the calender roll body 17, then start the second motor 16 to drive the bidirectional screw 14 to rotate, driving the two drive seats 15, the insertion seats 11 and the sliding inserts 12 closer to the calender roll body 17 until the brush is close to the outside of the calender roll body 17, pass the cleaning rod 21 through the inside of the calender roll body 17 and insert it into the side rod, slide the locking seat 19 to slide it to the outside of the cleaning rod 21, so that the locking block 22 is embedded in the two side blocks 23, start the first motor 8, drive the rotating rings 4 to rotate through the drive gear 9 and the gear ring 7, so that the calender roll body 17 rotates, and the cleaning brush and the brush clean the inside and outside of the calender roll body 17.
