Description

Technical Field

[0001] This utility model relates to the field of conveyor belt technology, and in particular to a detachable double-roller polypropylene brush device for conveyor belts. Background Technology

[0002] In industrial production, conveyor belts are crucial for material handling, and surface cleaning is paramount. However, traditional conveyor belt brush devices suffer from low cleaning efficiency. The single brush structure cannot adequately cover the conveyor belt surface, and the lack of effective linkage between brush rotation and conveyor belt operation makes it difficult to thoroughly remove dust, debris, and other contaminants from the conveyor belt surface, affecting its normal operation and lifespan. Furthermore, brush assemblies are typically fixed connections, making disassembly cumbersome when brushes wear out and need replacement. This requires multiple tools, consuming significant time and labor costs, and can easily damage other components of the device due to improper disassembly, severely impacting production efficiency and increasing operating costs. Therefore, we have introduced a detachable double-roller polypropylene brush device for conveyor belts. Utility Model Content

A base plate is fixedly connected to the lower rear end of the second mounting plate, and a connecting plate is fixedly connected to the rear end of the base plate. A control mechanism is fixedly installed on the upper end of the base plate, and two detachable brush assemblies are fixedly connected to the front end of the control mechanism. Several support rods are fixedly connected to the lower ends of both the first and second mounting plates. Fixing blocks are fixedly connected to the lower ends of the support rods, and fixing holes are formed at the upper ends of the fixing blocks.

[0006] Preferably, the detachable brush assembly includes a mounting head, a locking block, and a fixing screw. The mounting head has a locking hole at its front end, and three T-slots are formed on the inner wall of the locking hole. The outer surface of the mounting head has a first fixing screw hole that passes through both the inner and outer sides. Three T-blocks are fixedly connected to the outer surface of the locking block. A second fixing screw hole is formed on the outer surface of the locking block at a position between two T-blocks. A roller polypropylene brush body is fixedly connected to the front end of the locking block.

[0007] By adopting the above technical solution: the roller polypropylene brush body is made of polypropylene material, which has good rigidity and wear resistance. The bristles can maintain an upright shape and make full contact with the surface of the conveyor belt. During the rotation of the roller polypropylene brush body, the layered and staggered bristles can penetrate into the gaps and grooves on the surface of the conveyor belt to effectively remove adhering dust, debris and various material residues.

[0008] Preferably, the control mechanism includes a motor base, a servo motor is fixedly mounted on the upper end of the motor base, a drive gear is fixedly mounted on the output end of the servo motor, a drive toothed roller is fixedly connected to the front end of the drive gear, a conveyor belt body is meshed with the outer surface of the drive toothed roller, a driven toothed roller is meshed with the left side of the inner wall of the conveyor belt body, a plurality of transmission toothed rollers are meshed with the middle of the inner wall of the conveyor belt body, a rotating component is meshed with the outer surface of the drive gear, and the lower end of the motor base is fixedly connected to the upper end of the base plate.

[0009] By adopting the above technical solution, during the operation of the conveyor belt, several transmission toothed rollers can effectively disperse the tension on the conveyor belt body, avoiding the problem of deformation and deviation of the conveyor belt body due to excessive local force.

[0010] Preferably, the rear end of the servo motor is fixedly connected to the front end of the connecting plate, the front end of the servo motor is fixedly connected to the rear end of the second mounting plate, and the output end of the servo motor passes through the rear end of the second mounting plate and extends to the front end of the second mounting plate.

[0011] By adopting the above technical solution, the stability of the servo motor is guaranteed, and displacement or loosening of the servo motor is avoided, thereby providing a reliable guarantee for the stable operation of the entire brush device.

[0012] Preferably, the front end of the driving toothed roller, the front end of the driven toothed roller, and the front ends of the plurality of transmission toothed rollers are all movably connected to the rear end of the first mounting plate via a rotating shaft, and the rear end of the driven toothed roller and the rear end of the plurality of transmission toothed rollers are all movably connected to the front end of the second mounting plate via a rotating shaft.

[0016] Preferably, the rear ends of the second transmission gear, the third transmission gear, the fourth transmission gear, and the sixth transmission gear are all movably connected to the front end of the connecting plate via a rotating shaft.

[0017] By adopting the above technical solution, stable rotational support is provided for the second, third, fourth, and sixth transmission gears.

[0018] Preferably, the front ends of the fifth transmission gear and the sixth transmission gear are fixedly connected to the rear ends of the corresponding mounting heads.

[0019] By adopting the above technical solution, the front ends of the fifth and sixth transmission gears are directly fixedly connected to the rear ends of the corresponding mounting heads, which enables the power transmitted by the rotating components to be transmitted to the detachable brush components without loss and with high efficiency.

[0020] Preferably, the three T-slots are arranged in a circular array around the center of the mounting head, and the three T-slots and the three T-blocks are distributed in pairs.

[0021] By adopting the above technical solution, three T-slots are arranged in a circular array around the center of the mounting head and correspond to three T-blocks in pairs, forming a stable three-point snap-fit ​​structure. This structure can evenly distribute the centrifugal force and friction generated by the detachable brush assembly during rotation, effectively preventing the snap-fit ​​blocks from rotating, shifting, or loosening within the snap-fit ​​holes.

[0022] Preferably, the locking block is movably engaged in the locking hole, the three T-blocks are respectively movably engaged in the corresponding three T-slots, and the outer surface of the fixing screw is threadedly connected to the inner wall of the first fixing screw hole and extends into the second fixing screw hole.

[0023] By adopting the above technical solution, during installation, the operator only needs to align the T-shaped block of the card block with the T-shaped groove in the card hole and gently push it in to complete the initial positioning. No complicated alignment operation is required. Then, the entire installation process can be completed by tightening the fixing screw. No other tools are needed. When disassembling, simply unscrew the fixing screw to easily pull the card block out of the card hole. This convenient installation and disassembly method greatly shortens the equipment maintenance time.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. In this utility model, efficient cleaning is achieved through a control mechanism. When in use, the power is turned on and the servo motor is started. The servo motor drives the active gear at the output end to rotate. The active gear drives the active toothed roller to rotate synchronously. The active toothed roller meshes with the conveyor belt body, causing the conveyor belt body to run. At the same time, it drives the driven toothed roller and several transmission toothed rollers to rotate. During this process, while the active gear rotates, it drives the first transmission gear in the rotating assembly to rotate through the meshing relationship. Through the transmission of the second, third, fourth, and fifth transmission gears and the transmission belt, the sixth transmission gear rotates. This drives the mounting head fixedly connected to the front end of the sixth and fifth transmission gears, realizing the rotation of the two detachable brush assemblies. The double roller polypropylene brush body is in full contact with the conveyor belt body. During the continuous operation of the conveyor belt body, the continuously rotating double roller polypropylene brush body completes the cleaning of the surface of the conveyor belt body, significantly improving the cleaning efficiency.

[0026] 2. In this utility model, the detachable brush assembly design greatly facilitates maintenance. When the roller polypropylene brush body is severely worn and needs to be replaced, simply use a tool to unscrew the fixing screw. After the fixing screw is unscrewed from the first and second fixing screw holes, the locking block loses its fixing function. Since the locking block is engaged with the three T-slots on the inner wall of the mounting head's locking hole through three T-blocks, the locking block can be easily pulled out of the locking hole, realizing the quick separation of the worn roller polypropylene brush body from the mounting head and completing the disassembly. When replacing the new roller polypropylene brush body, simply align the T-blocks of the new locking block with the T-slots and insert them, then screw on the fixing screw. The operation is simple and convenient, greatly shortening maintenance time and reducing maintenance costs. Attached Figure Description
