Description

Technical Field

[0001] The utility model relates to an automatic loading and unloading device for logistics transportation, belonging to the technical field of logistics transportation. Background Art

[0002] Automatic loading and unloading in logistics transportation is an important link in the logistics system. Logistics transportation mainly refers to the transportation of goods between relatively fixed locations within the same site. This process is common in the handling of goods in factory workshops, or the movement of goods from one storage area to another in a warehouse. Its purpose is to meet the internal logistics needs of the production and storage process and save time and labor costs.

[0003] The existing patent number is CN221478615U, which is an automatic loading and unloading device for logistics transportation. This device can improve the stability of the device when loading and unloading goods by setting a tooth plate and a second conveyor belt. When in use, the DC motor is started to drive the second screw to rotate through the connecting block to move the tooth plate to the right, and then the tooth plate will drive the gear shaft to rotate to adjust the angle of the second conveyor belt. When the second conveyor belt is at a horizontal angle, the DC motor can be turned off to fix the position of the second conveyor belt. At this time, the second conveyor belt and the first conveyor belt can be started again to load and unload goods, and the materials are smoothly transferred to the first conveyor belt for transportation through the second conveyor belt, reducing the impact of the materials on the first conveyor belt and improving the stability. The stability of the high device during unloading can avoid damage to the goods. However, although this device can adjust the height of loading and unloading goods when in use, the first conveyor belt has an acute-angle structure after rotation, which makes it difficult to extend the first conveyor belt into the carriage to be loaded, and the second conveyor belt is relatively short, so manual longitudinal loading and placement is still required, which increases the intensity of manual labor; and this device cannot quickly adjust the horizontal position of the required load when in use, so when loading the goods into the carriage, manual movement is required before horizontal swinging is possible, or the position can be adjusted by pushing the entire device, which affects the efficiency of horizontal loading and placement and increases the labor intensity required for manual loading and unloading.
