Small to precision parts of electronic products, large to furniture and building materials, the traditional roller conveying device is difficult to meet the transportation needs of goods of different specifications. In actual application, if goods of different specifications are transported, the whole set of conveying equipment often needs to be replaced or reconfigured, which not only is cumbersome to operate, but also greatly increases the equipment purchase cost and maintenance cost, and frequent replacement of equipment also reduces the overall transportation efficiency, causing production stagnation and resource waste. This limitation seriously restricts the application expansion of the roller conveying device in complex logistics environment, and it is difficult to adapt to the efficient, flexible and diversified development trend of modern warehousing and logistics industry.

[0018] The embodiments of the technical scheme of the utility model will be described in detail below with reference to the drawings. The following examples are only used to more clearly illustrate the technical scheme of the utility model, therefore only as an example, and cannot limit the protection scope of the utility model.

[0019] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in the present application should be the usual meaning understood by the technical personnel in the field to which the utility model belongs.

[0020] Referring to Figure 1 and Figure 2 The roller conveying device provided in the embodiment mainly consists of a frame 1, a roller 2, a fixed guide device 3 and a movable guide device. The frame 1 is the main support structure of the device, and its stable frame design provides a solid foundation for the entire roller conveying device, which can withstand the weight and pressure in the process of goods transportation, ensures the stability of the device during operation, and avoids shaking or displacement caused by insufficient support. The fixed guide device 3 is arranged at both ends of the roller 2, like a reliable "pilot", which can effectively limit the lateral movement of the goods in the basic stage of goods transportation, so that the goods can move smoothly along the predetermined track, reduce the occurrence of unexpected situations such as goods deviation and sliding, and ensure the safety and reliability of goods transportation.

[0021] The activity guide device is the key innovative part of the embodiment, which is composed of lifting mechanism 4, guide wheel 5, guide support 6 and guide rod 7. The lifting mechanism 4 is installed on the rack 1, and can quickly and smoothly realize the conversion of the activity guide device between different working states by virtue of its lifting control ability. The guide wheel 5 is arranged at the top end of the lifting mechanism 4, and the rotating shaft of the guide wheel 5 extends in the vertical direction. This design enables the guide wheel 5 to provide strong side guiding support during the transportation of goods, effectively corrects the deviation of the goods, and ensures that the goods are always transported along the accurate path. The guide rod 7 is fixed in the vertical direction on the support, cooperates with the guide support 6, and provides a stable and smooth track for the sliding of the guide support 6. The guide support 6 extends along the length direction of the conveyor and is slidably arranged on the guide rod 7. A plurality of guide wheels 5 are arranged on the guide support 6 along the length direction. In this way, when the state of the activity guide device is switched, the plurality of guide wheels 5 can be lifted synchronously, ensuring the consistency and continuity of the guiding effect on the goods, and avoiding unnecessary impact or damage to the goods caused by asynchronous lifting of the guide wheels. At the same time, in order to ensure stability, the guide rod 7 and the lifting device are arranged in multiple, which greatly enhances the structural strength and anti-deformation ability of the entire activity guide device, and the multiple lifting devices work cooperatively, which can more evenly share the load, making the activity guide device more stable and reliable during lifting.

[0022] In another embodiment, guide rails 8 are arranged on the rack 1 along the width direction, and the mounting frame of the activity guide device can adjust the position along the width direction of the guide rails 8. The guide rod 7 and the lifting mechanism 4 are both installed on the mounting frame, and the guide channel width can be adjusted by adjusting the position of the mounting frame. Whether it is small goods or large goods, the guide channel can be accurately adjusted according to the specific size, so that the roller conveyor device can accurately adapt to goods of different sizes, significantly improving the versatility and practicality of the equipment.

[0023] The movable guiding device has two working states. When in the first state, the lifting mechanism 4 is at the low point, and the guiding wheel 5 is below the roller 2, which is suitable for transporting large-size goods. In this state, the large-size goods can roll on the roller 2 smoothly under the guidance of the fixed guiding device 3 on both sides of the frame 1 by virtue of the large size of the goods. The fixed guiding device 3 plays a major guiding role at this time, and the strong restraining ability can effectively control the direction of the large-size goods, so that even if the goods are slightly disturbed by external force during transportation, they can be quickly corrected back to the correct path, ensuring that the large-size goods can be safely and efficiently transported. When the movable guiding device is switched to the second state, the lifting mechanism 4 is raised to the high point, and the guiding wheel 5 is above the roller 2, which is suitable for transporting small-size goods. Small-size goods are prone to deviation or even falling during transportation due to their small size. At this time, the guiding wheel 5 and the fixed guiding device 3 on one side work together. The guiding wheel 5 limits the small-size goods from above, and the fixed guiding device 3 guides from the side. The two work together to accurately control the position and direction of the small-size goods, so that the small-size goods remain stable during transportation, effectively improving the accuracy and safety of small-size goods transportation.

[0024] In another embodiment, the movable guiding device is provided in two sets, and the two sets of movable guiding devices are symmetrically arranged with the center of the frame 1 in the width direction. A guiding channel is formed between the two sets. This symmetrical arrangement has significant advantages during goods transportation. When the goods are transported in the guiding channel, the two sets of movable guiding devices can evenly share the weight and lateral pressure of the goods, like two equally powerful guardians, effectively preventing unbalanced loading. Once the goods show a slight deviation tendency, the symmetrically arranged guiding devices can sense it in time and apply a reverse force to quickly adjust the goods back to the center position, ensuring the stability and reliability of the goods transportation. Even when transporting goods with uneven weight distribution, this symmetrical structure can keep the goods balanced through its own adjustment, avoiding equipment wear and tear and goods damage caused by unbalanced loading, thereby greatly prolonging the service life of the roller conveyor and reducing the maintenance cost of the equipment, while improving the overall efficiency of goods transportation.
