Technical Field

[0001] The utility model relates to the field of cleaning equipment, and particularly to a brush sealing structure of a cleaning machine and a cleaning machine. Background Art

[0002] In the brush mechanism of a cleaning machine, the design of the sealing structure is crucial because it can prevent moisture, dirt, and other impurities from entering the interior of the equipment, and at the same time prevent the internal liquid of the equipment from flowing out of the equipment, thereby protecting bearings and other sensitive components from damage and extending the service life of the equipment.

[0003] The existing sealing structure design is too complex, with high production costs and difficult replacement of sealing parts. A large number of components need to be disassembled for replacement, increasing the downtime and maintenance costs. Moreover, the sealing components are prone to wear during long-term use, resulting in poor sealing effects. Summary of the Utility Model

[0019] The following will describe in detail the specific implementation of the present utility model with reference to the drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present utility model, and is not used to limit the present utility model.

[0020] Please refer to Figure 1 , in one aspect, the present embodiment provides a cleaning machine brush sealing structure, which includes a first connecting part 1, a second connecting part 2, and a soft curtain 3 disposed between the first connecting part 1 and the second connecting part 2. There is a through channel axially between the first connecting part 1, the second connecting part 2, and the soft curtain 3.

[0021] Specifically, in this embodiment, both the first connecting portion 1 and the second connecting portion 2 are PVC rings, and the soft curtain 3 is an acid and alkali resistant soft curtain, which can also be made of PVC material. In actual production, since the area of the frame 101 of the cleaning machine is larger than the area of the mounting seat 102 of the rotating shaft 103 of the cleaning machine, and for better sealing, the sealing structure is usually set in a horn shape, that is, the diameter of the first connecting portion 1 is smaller than the diameter of the second connecting portion 2, and the two are connected by the soft curtain 3 to perform soft sealing on the brush mechanism of the cleaning machine. Since the soft curtain 3 itself has a certain elasticity, it can better adapt to its working environment during the operation of the cleaning machine, reduce the friction between the first connecting portion 1 and the second connecting portion 2 and the frame 101 and the mounting seat 102, reduce the wear speed of the components, and extend the service life of the equipment. Moreover, the PVC material itself also has acid and alkali resistance, and can better adapt to harsh working environments. Using PVC material to manufacture the sealing structure, the material is easy to obtain, the price is cheap, and it can be molded and mass-produced, greatly reducing the production cost.

[0022] Preferably, the first connecting portion 1, the second connecting portion 2, and the soft curtain 3 are integrally formed, avoiding the penetration of liquid or solid particles from the connection points of the first connecting portion 1, the second connecting portion 2, and the soft curtain 3 into the interior, and further improving the sealing performance and sealing effect of the sealing structure.

[0023] Preferably, the first connecting portion 1, the second connecting portion 2, and the soft curtain 3 are bonded together by a strong acid and alkali resistant sealant. The acid and alkali resistant glue can better assemble the structure, and can adapt to the acid and alkali environment, reducing the possibility of liquid or solid particle penetration.

[0024] Please refer to Figures 2 to 3 , a plurality of mounting holes 11 are provided on the first connecting portion 1, and the first connecting portion 1 is fixed on the mounting seat 102 of the rotating shaft 103 of the cleaning machine through a fixing member 12 passing through the mounting holes 11. The fixing member 12 is a bolt, and the mounting holes 11 are distributed along the circumference of the first connecting portion 1, which is more stable during fixation and more convenient and fast to install through bolts. And an oil seal is provided at the connection between the first connecting portion 1 and the rotating shaft 103 to further improve the sealing performance.

[0025] Preferably, a first gland 13 is provided on the side of the first connecting portion 1 away from the mounting seat 102. The fixing member 12 fixes the mounting seat 102, the first connecting portion 1, and the first gland 13 together, and the second connecting portion 2 is fixed on the frame 101 of the cleaning machine through a second gland 21.

[0026] Please refer to Figures 2 - 3, this embodiment provides a cleaning machine, which includes the above-mentioned cleaning machine brush sealing structure. Specifically, the cleaning machine includes a frame 101, a mounting seat 102 provided on the frame 101, a rotating shaft 103 passing through the mounting seat 102 and the frame 101, and a sealing structure provided outside the mounting seat 102. One end of the rotating shaft 103 passes through the frame 101 and is connected to a moving module 104 (brush cleaning mechanism), and the other end is externally connected to a driving mechanism through a coupling 105. In terms of the kinematic relationship, taking the frame 101 as the absolute reference system, the moving module 104 moves linearly relative to the frame 101, the rotating shaft 103 rotates relative to the moving module 104, and the mounting seat 102 is stationary relative to the moving module 06. During installation, the entire sealing structure is passed through the rotating shaft 103 to the sealing position, and the first connecting portion 1 and the first gland 13 are fixed to the mounting seat 102 by bolts, and then the second connecting portion 2 and the frame 101 are fixed together by the second gland 21, and then the coupling 105 is installed and externally connected to the driving mechanism. During disassembly, only the coupling 105 needs to be disassembled, then the first gland 13 and the second gland 21 are disassembled, and finally the sealing structure is taken out. The disassembly and assembly process is convenient, simple and fast, greatly reducing the downtime for maintenance, reducing the maintenance cost, and improving the cleaning efficiency.

[0027] Through the above technical solution, the brush sealing structure is connected in the form of a soft curtain seal, which not only has a simple structure and low production cost, but also greatly improves the sealing effect. During installation, only the first connecting portion 1 and the second connecting portion 2 need to be cooperatively installed, and the installation is convenient and fast, greatly reducing the downtime and saving the maintenance cost.

However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various simple modifications can be made to the technical solutions of the present invention, and these simple modifications all belong to the protection scope of the present invention. In addition, it should be noted that, in the above specific embodiments, the various specific technical features described can be combined in any appropriate manner without contradiction.
