Description

Technical Field

[0001] The utility model relates to the technical field of roller installation of a rubber filter, in particular to a fixing structure of a roller of a rubber filter. Background Art

[0002] Roller is a general term for cylindrical parts that can roll mechanically, and the roller of the rubber filter is a rolling part installed on the rubber filter. Its main function is to assist the rubber filter in filtering colloids.

[0003] Currently, when installing the roller on a rubber filter, it is necessary to use external tools and parts to install the roller. The installation steps are cumbersome and take a lot of time and effort. It is time-consuming and labor-intensive, and the function of quick installation cannot be achieved. At the same time, due to the different sizes of rubber filters, only rollers of specified lengths can be installed, and the fixed length cannot be adjusted according to the length of the roller. There are certain usage limitations. Therefore, we provide a fixing structure for the roller of a rubber filter. Utility Model Content

[0024] See also Figure 1-2 , the embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0025] Example

[0026] A technical solution adopted for the fixing structure of a rubber filter roller is: it includes a roller 1, a support frame 10 and a shell 3, the upper and lower ends of the inner cavity of the shell 3 are fixedly connected to dampers 16, and a spring 17 is wound around the surface of the damper 16, one end of the damper 16 is fixedly connected to a cross plate 18, one side of the cross plate 18 is fixedly connected to a limiting block 14, one end of the cross plate 18 is fixedly connected to a pull rod 2, one side of the inner cavity of the shell 3 is fixedly connected to a support block 19, and grooves 15 are provided on the top and bottom of both sides of the roller 1.

[0027] Specifically: when the roller shaft 1 needs to be installed, the user pulls the pull rod 2, and the cross plate 18 is driven to move toward one end through the pull rod 2. During the movement of the cross plate 18, the damper 16 and the spring 17 are squeezed, and at the same time, the limit block 14 is driven to move toward one end through the cross plate 18. After the movement is completed, the user inserts the roller shaft 1 into the inner cavity of the shell 3 and into the inner cavity of the support block 19. At this time, the user releases the pull rod 2 and uses the characteristics of the spring 17 to reset the structure, so that the limit block 14 is inserted into the groove 15, and the roller shaft 1 is limited, and the fixing work can be completed. The installation efficiency is high and the installation steps are simple.

[0028] A dual-axis motor 11 is fixedly installed at the center of the inner surface of the support frame 10, and the output end of the dual-axis motor 11 is fixedly connected to a threaded rod 7, and the surface of the threaded rod 7 is threadedly connected to a threaded sleeve 9, and the top of the threaded sleeve 9 is fixedly connected to a support column 6, and the top of the support column 6 is fixedly connected to the bottom of the shell 3. Bearings 8 are fixedly connected to both sides of the inner surface of the support frame 10, and one side of the threaded rod 7 is fixedly connected to the inner ring of the bearing 8. Slide grooves 12 are provided on both sides of the bottom of the inner surface of the support frame 10, and a slider 13 is fixedly connected to the bottom of the threaded sleeve 9. The bottom of the slider 13 is slidably connected to the inner cavity of the slide groove 12. The bottom of both sides of the support frame 10 is fixedly connected to the Yuu mounting block 4, and the inner cavity of the mounting block 4 is provided with a screw hole 5.

[0029] Specifically: before installing the roller shaft 1, the user starts the dual-axis motor 11 to work, and the dual-axis motor 11 drives the left threaded rod 7 to rotate clockwise, and drives the right threaded rod 7 to rotate counterclockwise, which can drive the threaded sleeve 9 to move in the opposite direction, and drives the support column 6 to move to one side through the threaded sleeve 9, and drives the shell 3 to move to one side through the support column 6, and stops when it moves to the required length of the roller shaft 1. It is suitable for the installation of roller shafts 1 of different lengths and has no usage restrictions. Through the setting of the bearing 8, the wear of the threaded rod 7 during rotation is reduced, and the loss of the threaded rod 7 during rotation is reduced, thereby greatly improving the service life of the threaded rod 7. During the movement of the threaded sleeve 9, the slider 13 is driven by the threaded sleeve 9 to slide in the inner cavity of the slide groove 12, thereby reducing the jitter of the threaded sleeve 9 during movement, and greatly improving the stability of the threaded sleeve 9 during movement. The user uses an external tool to turn the mounting bolt into the screw hole 5 and the rubber filter machine to complete the installation of the fixing device.

[0030] The working principle of the utility model is as follows: before installing the roller shaft 1, the user starts the dual-axis motor 11 to work, and the dual-axis motor 11 drives the left threaded rod 7 to rotate clockwise, and drives the right threaded rod 7 to rotate counterclockwise, which can drive the threaded sleeve 9 to move in the opposite direction, and drives the support column 6 to move to one side through the threaded sleeve 9, and drives the shell 3 to move to one side through the support column 6, and stops when it moves to the required length of the roller shaft 1. It is suitable for the installation of roller shafts 1 of different lengths, without usage restrictions, and the adjustment is completed when the roller shaft needs to be adjusted. During installation, the user pulls the pull rod 2, which drives the horizontal plate 18 to move toward one end. During the movement of the horizontal plate 18, the damper 16 and the spring 17 are squeezed, and at the same time, the limit block 14 is driven to move toward one end through the horizontal plate 18. After the movement is completed, the user inserts the roller shaft 1 into the inner cavity of the shell 3 and the inner cavity of the support block 19. At this time, the user releases the pull rod 2 and uses the characteristics of the spring 17 to reset the structure, so that the limit block 14 is inserted into the groove 15, and the roller shaft 1 is limited. The fixing work can be completed, and the installation efficiency is high and the installation steps are simple.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the scope of protection of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
