Description

Technical Field

[0001] The utility model relates to the technical field of material conveying, in particular to a transmission structure for a conveying roller. Background Art

[0002] Conveyor rollers are cylindrical material handling components, typically consisting of a bearing, housing, shaft, and roller body. Supported by chains, belts, or other load-bearing structures, they enable items to be moved from one location to another. Conveyor rollers are widely used in a variety of industries, including logistics, manufacturing, supply chain, warehousing, packaging, food manufacturing, and metalworking. Conveyor rollers play an important role in the material handling process, specifically in the following ways:

[0003] Save labor: Conveyor rollers achieve continuous or intermittent material conveying through mechanization, significantly saving labor costs. Improve production efficiency: Conveyor rollers can quickly and accurately transport materials to designated locations, improving production efficiency. Reduce cargo wear: Conveyor rollers use rolling friction instead of sliding friction, reducing material wear during the conveying process. Ensure cargo transportation safety: Conveyor rollers can convey materials smoothly and continuously, avoiding damage or safety accidents caused by material bumps or stagnation. Strong adaptability: Conveyor rollers can be customized according to different conveying requirements, such as changing length, diameter, material, etc., to adapt to different types of materials and conveying environments.

[0004] However, in practical use, existing conveyor systems often use conveyor rollers, a common transmission component. These are driven by motors to achieve continuous or intermittent material transport. However, traditional conveyor rollers often have a single conveying direction, making them difficult to quickly adjust to meet production needs. Changing direction often requires reconfiguring the entire conveyor line, which not only increases costs but also reduces system flexibility and efficiency. Utility Model Content

[0005] The present utility model aims to provide a transmission structure for conveyor rollers to address the problem raised in the background art above. Conveyor rollers are commonly used transmission components in existing material conveying systems. They are driven by motors to achieve continuous or intermittent material conveyance. However, conventional conveyor rollers often have a single conveying direction, making it difficult to quickly adjust to meet production needs. To achieve this direction change, the entire conveyor line must be reconfigured, which not only increases costs but also reduces system flexibility and efficiency.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: comprising a central support platform, a front support platform and a rear support platform, wherein the upper ends of the front support platform and the rear support platform are respectively supported and rotatably connected to a front driven roller and a rear driven roller through bearing seats, a synchronization shaft is fixedly installed on the outer sides of the front driven roller and the rear driven roller, a first synchronization sprocket and a second synchronization sprocket are respectively fixedly installed on both sides of the outer curved surface of the synchronization shaft, and the outer ends of the first synchronization sprocket and the second synchronization sprocket are sequentially meshed and connected with a synchronization chain;

[0007] The transmission gear of said first transmission shaft is connected with the transmission gear of said second transmission gear of said first transmission gear and the transmission gear of said second transmission gear is connected with the transmission gear of said second transmission gear. The transmission gear of the present invention is a gear which is connected to the transmission gear of the present invention and is pivotally connected to the transmission gear of the present invention. The transmission gear of the present invention is a gear which is connected to the transmission gear of the present invention.

[0008] Preferably, there are several front driven rollers and rear driven rollers, which are symmetrically distributed on the upper ends of the front support platform and the rear support platform respectively.

[0009] Preferably, the first transmission shaft is rotatably connected to the outer side of the lower end of the central support platform through a bearing seat.

[0010] Preferably, the second transmission shaft is rotatably connected to the outer side of the upper end of the central support platform through a bearing seat.

[0011] Preferably, the third transmission shaft is rotatably connected to the inner wall of the central support platform via a rotating shaft.

[0012] Preferably, the fourth transmission sprocket is fixedly mounted on the outer curved surfaces of the side ends of the front drive shaft and the rear drive shaft respectively.

[0013] Preferably, the fifth transmission sprocket is meshedly connected to the inner side of the synchronous chain.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The utility model controls the rotation directions of the front reduction motor and the rear reduction motor respectively when the front reduction motor and the rear reduction motor are respectively controlled. When the rotation directions of the front reduction motor and the rear reduction motor are respectively controlled, the front driving roller and the rear driving roller cooperate with the front driven roller and the rear driven roller to uniformly move the rotation and conveying directions forward and backward or inward and outward.
