[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.
[0020] Example 1
[0021] The utility model provides an easy-to-clean dust-sticking roller, such as Figures 1-4As shown, it includes: a roller 1, an end cover 2 and a connecting shaft 3, a through groove 15 is opened inside the end cover 2, a fixed bracket 4 is fixedly installed inside the end cover 2, one side of the fixed bracket 4 is fixedly connected to a spring 5, and the end of the spring 5 away from the fixed bracket 4 is fixedly connected to a cross plate 6, and a cross bar 7 is connected inside the cross plate 6, and a limiting groove 8 is opened at the position corresponding to the position of the cross bar 7 inside the roller 1, and a threaded tube 11 is connected to the inside of the connecting shaft 3 through a thread, and a cross groove is opened at one end of the threaded tube 11, which is convenient for the staff to use tools to embed into the cross groove, so as to facilitate the rotation of the threaded tube 11 inside the connecting shaft 3, and a bearing 12 is fixedly connected to the inner ring of the bearing 12 by an interference fit. The end of the cross bar 7 away from the limiting groove 8 is in sliding contact with one end of the push rod 9, and a bottom plate 10 is installed at one end of the push rod 9 inside the end cover 2. The four sides are fixedly connected to one side of the fixed bracket 4, and a through hole 16 is opened inside the bottom plate 10. By rotating the threaded tube 11 and cooperating with the action of the bearing 12, the threaded tube 11 pushes the push rod 9 to move downward during the rotation of the connecting shaft 3. The push rod 9 moves downward and pushes the cross bar 7 to move in the direction close to the roller 1, and then one end of the cross bar 7 moves to the limiting groove 8 opened inside the roller 1, thereby fixing the end cover 2 to the end of the roller 1, thereby ensuring that the end covers 2 at both ends of the sticky roller can be fastened to the two ends of the roller 1 when the sticky roller rotates at work, ensuring the stability of the device when the sticky roller is in use, thereby improving the efficiency of the device in cleaning dust. The number of fixed brackets 4, springs 5, cross plates 6, cross bars 7 and limiting grooves 8 are all set to four. By symmetrically installing equipment components inside the device, the entire device is evenly stressed when the roller 1 rotates, ensuring the stable operation of the device.
[0022] like Figure 3 As shown, a limiting bracket 13 is integrally formed on the outer side of the push rod 9, and a slide groove 14 is provided inside the connecting shaft 3 at a position corresponding to the position of the limiting bracket 13, so that when the staff rotates the threaded tube 11, the slide groove 14 and the limiting bracket 13 can be used to control the running trajectory of the push rod 9 and avoid the push rod 9 from being offset during movement.
[0023] Working principle: When using the device, the staff rotates the threaded tube 11 inside the connecting shaft 3 to move the threaded tube 11 toward the end cover 2. With the action of the bearing 12, the threaded tube 11 drives the push rod 9 toward the bottom plate 10 when moving, so that the push rod 9 pushes the cross bar 7 toward the limit groove 8 opened inside the roller 1, so that the spring 5 is deformed by the force, and one end of the cross bar 7 moves to the inside of the limit groove 8, so that the end cover 2 is fixed to one end of the roller 1, so that the sticky roller maintains the stability of the entire device when working, preventing it from Excessive vibration or displacement occurs during use, thereby extending the service life of the dust-sticking roller and maintaining the stability and accuracy of the equipment operation. When the end cover 2 needs to be removed, the threaded tube 11 is rotated in the opposite direction so that the threaded tube 11 drives the push rod 9 to move away from the end cover 2, thereby causing one end of the push rod 9 to disengage from the through hole 16 opened inside the bottom plate 10. At this time, the spring 5 returns to its original state due to the deformation, and then drives the cross bar 7 to move away from the limit groove 8, thereby causing the end cover 2 to disengage from one end of the roller 1, achieving the purpose of disassembly and facilitating replacement by the staff.
[0024] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
