[0039] Reference Figure 1-Figure 5 , this embodiment provides a roller brush mechanism, including a driving device 1, a supporting device 2 and a plurality of cleaning devices 3;

[0040] The driving device 1 includes a power transmission component 10 and a rotating shaft 11. The power transmission component 10 is arranged on the supporting device 2. One end of the rotating shaft 11 is detachably connected to the power transmission component 10.

[0041] The cleaning device 3 includes a roller brush connecting plate 30, a roller brush body 31 and a fastening piece 32. The roller brush body 31 is detachably mounted on the rotating shaft 11. The fastening piece 32 is arranged on the roller brush body 31 and abuts against the rotating shaft 11. The roller brush connecting plate 30 is detachably arranged at one end of the supporting device 2 away from the power transmission component 10, and the other end of the rotating shaft 11 is rotatably connected to the roller brush connecting plate 30.

[0042] In the above embodiment, the roller brush mechanism mainly includes a driving device 1, a supporting device 2 and a plurality of cleaning devices 3. The driving device 1 includes a power transmission component 10 and a rotating shaft 11, wherein the power transmission component 10 is arranged on the supporting device 2 and is responsible for providing rotational force. The rotating shaft 11 is the core component of power transmission, and one end of the rotating shaft is connected to the power transmission component 10 in a detachable manner, thereby receiving power from the motor and transmitting it to the roller brush. The supporting device 2 provides structural support for the entire system to ensure that each component can work stably. The cleaning device 3 is the part that directly contacts the product, including a roller brush connecting plate 30, a roller brush body 31 and a fastener 32. The roller brush connecting plate 30 is installed on the end of the support device 2 away from the power transmission component 10 by means of bolts or the like to ensure that the roller brush will not be displaced during work. The roller brush body 31 is the part that actually performs the cleaning task. It is installed on the rotating shaft 11 in a sleeve manner and fixed by a set screw (i.e., the fastener 32) to prevent loosening or slipping during operation.

[0043] When the roller brush body 31 needs to be disassembled and replaced, the four screws connecting the roller brush connecting plate 30 and the connecting rod 211 are first loosened, and the entire cleaning device 3 is then pulled out. At this time, the rotating shaft 11 is connected to the roller brush connecting plate 30 and remains stationary. It is only necessary to separate the rotating shaft 11 from the power transmission component 10, and then loosen the set screws to remove the roller brush body 31 from the rotating shaft 11, and then replace it with a new roller brush body 31. Therefore, the roller brush body 31 is detachably connected to the rotating shaft 11 by the set screws, so that the roller brush mechanism can be disassembled and assembled by simply loosening the set screws with ordinary tools, eliminating the need to purchase expensive special tools, reducing tool procurement and maintenance costs, and eliminating the need for professional skilled personnel to disassemble and assemble, thus reducing labor costs. At the same time, the roller brush can be quickly disassembled and assembled by loosening the set screws, with fewer operating steps, which can significantly shorten disassembly and assembly time, reduce equipment downtime, and improve production efficiency. In addition, the use of set screws for connection causes less damage to the mating surfaces, and the good mating accuracy can be maintained after multiple disassembly and assembly, ensuring stable operation of the roller brush and improving product processing quality.

[0044] Reference Figure 1-Figure 3 In one embodiment, the support device 2 includes a driving support plate 20 and multiple groups of connecting components 21, the power transmission component 10 is connected to the driving support plate 20, the driving support plate 20 is connected to the roller brush connecting plate 30 through the connecting component 21, and the driving support plate 20 and the roller brush connecting plate 30 are arranged opposite to each other, and the rotating shaft 11 with the roller brush body 31 is arranged between adjacent connecting components 21.

[0045] In the above embodiment, the support device 2 is composed of a driving support plate 20 and multiple groups of connecting components 21. The driving support plate 20 carries the power transmission component 10, that is, the power transmission component 10 is connected to the driving support plate 20, and the driving support plate 20 is connected to the roller brush connecting plate 30 through multiple groups of connecting components 21 to form a stable overall frame. The driving support plate 20 and the roller brush connecting plate 30 are arranged relative to each other to ensure the stability of the entire system. Two bearing placement holes are provided on the roller brush connecting plate 30. One end of each rotating shaft 11 is connected to the power transmission component 10, and the other end passes through these bearing placement holes and is rotated by supporting bearings. This not only ensures the stable rotation of the rotating shaft 11, but also reduces friction and extends the service life. There are two groups of connecting components 21, which are respectively located at both ends of the driving support plate 20. The roller brush body 31 is sleeved on the rotating shaft 11 and is located between adjacent connecting components 21, so that the roller brush can maintain good balance and stability during work, thereby improving the stability and reliability of the system.

[0046] Reference Figure 1-Figure 3 In one embodiment, the connecting assembly 21 includes a fixed block 210 and at least two connecting rods 211, the two ends of the connecting rod 211 are respectively connected to the driving support plate 20 and the roller brush connecting plate 30 by bolts, the fixed block 210 is connected to the side of the driving support plate 20 close to the roller brush connecting plate 30, and the fixed block 210 is clamped on the connecting rod 211.

[0047] In the above embodiment, the connecting assembly 21 is composed of a fixed block 210 and at least two connecting rods 211. The two ends of each connecting rod 211 are respectively connected to the drive support plate 20 and the roller brush connecting plate 30 by bolts. The fixed block 210 is located on the side of the drive support plate 20 close to the roller brush connecting plate 30, and is fixed to the connecting rod 211 by clipping. By using the combination of the fixed block 210 and the connecting rod 211, the connection strength and stability between the drive support plate 20 and the roller brush connecting plate 30 are greatly enhanced, and the risk of structural loosening due to vibration or impact is reduced.

[0048] Furthermore, each connecting rod 211 is provided with a snap-fitting groove 212 at one end close to the driving support plate 20 for cooperating with the snap-fitting portion 214 on the fixing block 210. The snap-fitting groove 212 is usually two opposite planes, so that they can be in close contact with the snap-fitting portion 214 of the fixing block 210; the fixing block 210 is a rectangular structure, and a receiving groove 213 is provided at its end. The receiving groove 213 is a U-shaped groove, and a snap-fitting portion 214 is formed on the inner wall of the side away from the driving support plate 20. The snap-fitting portion 214 extends along the entire circumference of the receiving groove 213 and protrudes inwardly, and its width is approximately 2 13, thereby forming a U-shaped structure. When the connecting rod 211 is inserted into the receiving groove 213, the clamping portion 214 will press against the clamping groove 212 of the connecting rod 211 to ensure the firmness and stability of the connection. In order to ensure the symmetry and balance of the overall structure, an accommodating groove 213 is provided at each end of the fixing block 210, and the two connecting rods 211 are respectively located in these two symmetrical accommodating grooves 213. Due to the close fit between the clamping portion 214 and the clamping groove 212, good connection performance can be maintained even in a high-intensity working environment, ensuring the stable operation of the equipment.

[0049] Reference Figure 1-Figure 4 In one embodiment, the driving support plate 20 includes a motor support portion 201 and a roller brush support portion 202 integrally connected to the motor support portion 201. The power transmission component 10 includes a driving motor assembly 101, a synchronous wheel assembly 102 and a belt 103. The synchronous wheel assembly 102 is arranged on a side of the roller brush support portion 202 away from the driving support plate 20 for connecting to the rotating shaft 11. The driving motor assembly 101 is arranged on the motor support portion 201, and the driving motor assembly 101 is connected to the synchronous wheel assembly 102 through the belt 103.

[0050] In the above embodiment, the driving support plate 20 is composed of a motor support part 201 and a roller brush support part 202 integrally connected thereto. The integrated design of the motor support part 201 and the roller brush support part 202 greatly simplifies the assembly and maintenance process, reduces the number and complexity of parts, and thus reduces the manufacturing cost. The motor support part 201 is mainly used to carry the driving motor assembly 101. The motor support part 201 is designed as a solid flat plate structure that can stably install the motor and is fixed to the equipment frame by bolts and the like. The roller brush support part 202 is directly arranged on one side of the motor support part 201 to form an integral structure. Its main function is to provide a synchronous wheel. Component 102 provides an installation platform and ensures that the rotating shaft 11 can run smoothly. A specific position is provided on the side of the roller brush support part 202 away from the motor support plate for installing the synchronous wheel component 102. These synchronous wheel components 102 are connected to the drive motor component 101 through a belt 103, that is, the synchronous wheel component 102 is arranged on the side of the roller brush support part 202 away from the motor support part 201. They receive power from the drive motor component 101 through the belt 103 and transmit the power to the rotating shaft 11, so that the roller brush body 31 can rotate at a predetermined speed, achieve smooth and precise speed control, and effectively reduce mechanical wear and extend the service life of the equipment.

[0051] Reference Figure 1-Figure 4 In one embodiment, the drive motor assembly 101 includes a motor body 1010, a motor connecting plate 1011 and a motor wheel 1012, the motor connecting plate 1011 is arranged on the side of the motor support portion 201 away from the roller brush connecting plate 30, and the motor support portion 201 is provided with a through hole 203 corresponding to the motor connecting plate 1011, a portion of the motor body 1010 is located in the through hole 203 and connected to the motor connecting plate 1011, the motor wheel 1012 is located on the side of the motor connecting plate 1011 away from the motor support portion 201, and the motor wheel 1012 is connected to the motor body 1010 through a motor shaft passing through the motor connecting plate 1011.

[0052] In the above embodiment, the driving motor assembly 101 consists of a motor body 1010, a motor connecting plate 1011 and a motor wheel 1012. The motor body 1010 is the core part that provides the rotational force, and it outputs the power through the motor shaft. The motor connecting plate 1011 is a key intermediate component, which is arranged on the side of the motor support part 201 away from the roller brush connecting plate 30. The motor connecting plate 1011 is provided with a circular through hole that matches the motor shaft for passing through and fixing the motor shaft. The motor support part 201 is provided with a square through hole 203, and the position of the through hole 203 corresponds to the circular through hole on the motor connecting plate 1011, so that a part of the motor body 1010 can pass through the motor support part 201 and It is tightly connected to the motor connecting plate 1011 by means of bolts or the like; the motor wheel 1012 is located on the side of the motor connecting plate 1011 away from the motor support part 201, and is connected to the motor body 1010 through the motor shaft. The motor shaft passes through the circular through hole on the motor connecting plate 1011 to ensure that the motor wheel 1012 can rotate smoothly under the drive of the motor body 1010. The square through hole on the motor support part 201 is designed to adapt to the external dimensions of the motor body 1010 to ensure that the motor body 1010 can be firmly installed on the equipment frame. The existence of the motor connecting plate 1011 not only simplifies the installation process of the motor body 1010, but also enhances the overall rigidity of the system and reduces vibration and noise during operation.

[0053] Reference Figure 1-Figure 4 In one embodiment, the synchronous wheel assembly 102 includes a first synchronous wheel 1020 and a second synchronous wheel 1021, the first synchronous wheel 1020 and the second synchronous wheel 1021 are arranged at intervals on the roller brush support portion 202, and the motor wheel 1012 is located on the central axis of the connecting line between the first synchronous wheel 1020 and the second synchronous wheel 1021.

[0054] In the above embodiment, the synchronous wheel assembly 102 includes a first synchronous wheel 1020 and a second synchronous wheel 1021, which are arranged at intervals on the roller brush support portion 202 and are connected to the motor wheel 1012 through the belt 103 to form an equilateral triangle power transmission structure. The first synchronous wheel 1020 and the second synchronous wheel 1021 are respectively located on both sides of the roller brush support portion 202, and the motor wheel 1012 is located on the central axis between the two. Each synchronous wheel is connected to the rotating shaft 11 through a bearing in a bearing hole. The rotating shaft 11 is sleeved on the synchronous wheel. Two bearing holes are provided in the roller brush support portion 202, and a shaft is installed in each bearing hole. The bearing is used to support the rotational movement of the synchronous wheel. The first synchronous wheel 1020 and the second synchronous wheel 1021 are respectively connected to a rotating shaft 11. A roller brush body 31 of the cleaning device 3 is mounted on each rotating shaft 11. When the motor drives the motor wheel 1012 to rotate, the power is transmitted to the first synchronous wheel 1020 and the second synchronous wheel 1021 through the belt 103, and then the respective rotating shafts 11 are driven to rotate through the action of the bearing, so that the roller brush body 31 can work at a predetermined speed. By adopting an equilateral triangle power transmission structure, the tension of the belt 103 transmission is evenly distributed, which reduces the wear of the belt 103 and improves the transmission efficiency.

[0055] Reference Figure 1-Figure 4 In one embodiment, the roller brush mechanism further includes a protective cover 4 corresponding to the driving support plate 20 , the protective cover 4 covers the power transmission component 10 , and the protective cover 4 is connected to the driving support plate 20 .

[0056] In the above embodiment, the roller brush mechanism includes a protective cover 4, which corresponds to the drive support plate 20 and covers the power transmission component 10. The main function of the protective cover 4 is to provide protection for the synchronous wheel assembly 102, the belt 103, the motor wheel 1012 and the motor connecting plate 1011, preventing external dust and debris from entering the system, thereby ensuring the normal operation of these key components. The protective cover 4 is tightly connected to the drive support plate 20 by bolts or other fixing methods to form a closed but accessible space. The synchronous wheel assembly 102, the belt 103, the motor wheel 1012 and the motor connecting plate 1011 are located within the protective cover 4. In addition, an opening is provided at the top of the protective cover 4, that is, near the top of the motor connecting plate 1011. This opening is located in the middle of the top of the protective cover 4, which facilitates the operator to observe the internal situation and check the tension of the belt 103, the status of the synchronous wheel and the overall operating status without having to completely remove the protective cover 4. This effectively prevents external pollutants such as dust and oil from entering the power transmission component 10 area, thereby extending the service life of these key components.

[0057] Reference Figure 1-Figure 5In one embodiment, the roller brush body 31 includes a roller brush barrel 310 and multiple groups of bristles 311. The roller brush barrel 310 is sleeved on the rotating shaft 11. The multiple groups of bristles 311 are arranged at specified intervals on the side of the roller brush barrel 310 away from the rotating shaft 11, and adjacent bristles 311 are staggered.

[0058] In the above embodiment, the roller brush body 31 is composed of two main parts: a roller brush barrel 310 and multiple groups of bristles 311. The roller brush barrel 310 is a cylindrical structure with a hole designed inside to fit the rotating shaft 11, so that the roller brush barrel 310 can be sleeved on the rotating shaft 11 and rotate with the rotation of the rotating shaft 11. The multiple groups of bristles 311 are arranged at specified intervals on the side of the roller brush barrel 310 away from the rotating shaft 11, which means that the bristles 311 are not continuously distributed on the surface of the entire roller brush barrel 310, but are arranged in several groups. Each group of bristles 311 extends along the length direction of the roller brush barrel 310, usually with a length of three-quarters or four-fifths of the entire roller brush barrel 310, and each group of bristles 311 consists of multiple bristles arranged at intervals. The bristles 311 are composed of 311 individuals, and a certain distance is maintained between these bristles 311 individuals so as to better adapt to different surface shapes and improve the cleaning effect. The interval angle between adjacent bristle 311 groups is 10-15 degrees. This staggered arrangement makes the bristles 311 individuals in adjacent bristle 311 groups correspondingly located in the middle of two bristle 311 individuals in adjacent bristle 311 groups. At the same time, an air blowing and dust suction auxiliary device can also be installed. When one group of bristles 311 completes a cleaning, the next contact point will fall in the middle position of the other group of bristles 311, thereby forming a more uniform and dense coverage effect. This design not only improves the cleaning coverage rate, but also effectively reduces the missed areas, ensuring that every corner can be thoroughly cleaned.

[0059] Reference Figure 1-Figure 5 In one embodiment, a supporting groove 312 is provided on the rotating shaft 11, and at least two screw holes 313 are provided on one end of the roller brush 310 away from the bristles 311, and the fastener 32 is screwed into the screw hole 313 and abuts against the supporting groove 312.

[0060] In the above embodiment, the shaft 11 is provided with a top groove 312 for cooperating with a fastening member 32 (such as a set screw) to achieve a stable fixation of the roller brush drum 310. The top groove 312 is usually located at both ends of the shaft 11, and two opposite top grooves 312 are formed on each end. The roller brush drum 310 is provided with at least two screw holes 313 at one end away from the bristles 311. These holes are used to insert the fastening member 32 so that the fastening member 32 can be screwed into and finally abutted against the top groove 312 on the shaft 11. In order to ensure the reliability and stability of the fixation, the roller brush drum 310 is fixed with a screw hole 313. Two screw holes 313 are respectively provided at both ends of 10, and these two screw holes 313 are arranged at 90 degrees. When the tightening screw is screwed into the screw hole 313 and contacts the top groove 312, it will apply a certain pressure to prevent the roller brush barrel 310 from being displaced or loosened on the rotating shaft 11. Since the screw holes 313 are arranged at 90 degrees, the tightening screw can provide uniform pressure distribution in different directions, further enhancing the stability of the entire system. This layout not only improves the fastening effect, but also disperses the fixing stress, avoiding loosening or damage caused by single-point force.
