Technical Field

[0001] This utility model relates to the field of roller conveying technology, and in particular to an anti-impact damping roller conveying device. Background Technology

[0002] In the field of logistics and express delivery, roller conveyors play a crucial role. They mainly consist of a drive unit, rollers, and a frame. The drive unit provides power, rotating the rollers to achieve smooth delivery of packages. Its working principle is not complex: when a package is placed on the rotating rollers, the friction between the rollers propels the package along a predetermined direction. In actual logistics scenarios, this type of conveyor offers significant advantages. It can efficiently and continuously transport large quantities of packages, greatly improving logistics efficiency; it also has strong adaptability, allowing for flexible adjustments and layouts based on different sites and package sizes; furthermore, its simple structure and ease of maintenance reduce operating costs. With these characteristics, roller conveyors have become indispensable equipment in the logistics industry, contributing to its rapid development.

[0003] The existing roller conveyor system has inconveniences in adjusting the damping force, and its overall practicality needs to be improved. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An impact-resistant damping roller conveying device includes a support base. Multiple roller structures are rotatably mounted on the upper end of the support base. Each roller structure includes an inner rotating shaft. A rotating cylinder is rotatably sleeved on the outside of the inner rotating shaft. Multiple mounting positions are provided at the middle position of the inner rotating shaft, and hydraulic rods are fixedly installed inside each mounting position.

[0007] By adopting the above technical solution, the tightness of the fit between the damping block and the inner wall of the drum can be effectively adjusted, thereby adjusting the damping force of the roller structure.

[0008] Furthermore, a connecting seat is fixedly installed on the side surface of the support base, one end of the inner rotating shaft communicates with the interior of the connecting seat, an adjusting tube is fixedly connected to the lower surface of the connecting seat, an adjusting screw is threadedly connected to the end face of the adjusting tube, and a piston block is rotatably connected to one end of the adjusting screw, with the piston block located inside the adjusting tube.

[0009] By adopting the above technical solution, the hydraulic oil pressure inside the connecting seat can be adjusted flexibly and conveniently.

[0010] Furthermore, a multi-groove pulley is externally sleeved and fixed at one end of the inner rotating shaft, and a belt is externally sleeved on the two adjacent multi-groove pulleys.

[0011] By adopting the above technical solution, it can be ensured that kinetic energy can be transmitted to each roller structure.

[0012] Furthermore, a motor base is fixedly connected to the side surface of the support base, and a motor is fixedly installed on the end face of the motor base. One end of the rotating shaft of the motor is fixedly connected to the middle position of one of the inner rotating shaft end faces.

[0018] In summary, the beneficial technical effects of this utility model are as follows:

[0019] 1. This utility model allows for adjustment of the damping force of the roller structure according to the type and size of the conveyed items. During adjustment, the adjusting screw is turned to adjust the position of the piston block inside the adjusting tube, thereby adjusting the hydraulic oil pressure in the connecting seat and the inner rotating shaft, which in turn adjusts the extension length of the hydraulic rod. Since the extension rod is fixedly connected to the extension end of the hydraulic rod, and a spring is sleeved on the outside of the extension rod, and the damping block is fixedly connected to one end of the extension rod, the compression degree of the spring can be adjusted, effectively adjusting the tightness of the fit between the damping block and the inner wall of the rotating drum, thereby adjusting the damping force of the roller structure. The adjustment operation is flexible and convenient, and it is highly practical.

[0020] 2. When using this device to transport objects, multiple through holes inside the rubber sleeve can be used to achieve buffering and shock absorption. The protective frame fixed to the outer surface of the rotating drum can be used to improve the anti-collision performance of the entire roller structure, preventing the conveying device from being damaged by heavy express items. The overall structural strength is effectively improved, and the practicality is further enhanced. Attached Figure Description
