[0002] In the logistics industry, loading and unloading are the most labor-intensive and cost-intensive parts, and there are various ways to load goods, some of which are placed on pallets and directly transferred with the pallets, some of which are directly transferred by adsorbing the goods box, and even some of which are still in the manual carrying mode, which is carried from the vehicle entrance or the side of the vehicle.
[0003] The traditional mechanical carrying mode, such as mechanical hand stacking and walking gantry stacking, not only requires the truck to be moved to a designated position, but also needs to adjust the length or other parameters of the transfer equipment according to the size of the truck, which has many pre-steps. Some existing equipment allows the transfer equipment to directly enter the interior of the truck, thereby reducing the pre-matching steps and improving the transfer efficiency. Although this method can reduce the pre-adjustment steps, in fact, the width of each vehicle is different. If the equipment is set too wide, it cannot adapt to narrow vehicles. If the equipment is set too narrow, it needs to adjust the position of the vehicle multiple times when facing wide vehicles, re-correct the position and re-confirm the position of the goods, which requires a lot of time.

[0018] It is mentioned above that the lateral material guiding structure is adjustable, therefore, the distance between the power roller and the lateral guide roller changes, if the traditional belt or chain is used, the belt is too tight or too loose to provide power, therefore, the two hinge plates and the movable wheel are used to connect the belt in the utility model, the included angle of the two hinge plates can be automatically adjusted according to the gap between the power roller and the lateral guide roller, so that the belt can be always tight and provide transmission effect for the lateral guide roller and the power roller.

[0035] The guide rollers in the lateral material guiding structure 32 are not all provided with power, otherwise the overall energy cost is high, therefore the lateral material guiding structure 32 in the embodiment comprises a plurality of lateral guide rollers 321 slidingly arranged in the area on both sides of the front end of the mounting rack 10, at least one powered roller 322 is arranged between the lateral guide rollers 321, the powered roller 322 is connected with the lateral guide rollers 321 and the lateral guide rollers 321 through the movable adjusting member 323, at least one compensation strip 324 is connected between the mounting seat outside the shaft head of the two ends of the powered roller 322 or the lateral guide rollers 321, at least one powered roller 322 is arranged in the lateral material guiding structure 32, which assists a plurality of lateral guide rollers 321, and the powered roller 322 and the lateral guide rollers 321 are linked through the movable adjusting member 323, so that the lateral guide rollers 321 also have power, so that the goods can move faster and more stably to the middle, and in order to avoid the problem that the gap between the lateral guide rollers 321 and the powered roller 322 is too large, causing the goods to slip, the compensation strip 324 with elasticity is arranged on the powered roller 322 or the lateral guide rollers 321, so that the goods have a larger contact area with the transfer device.
[0036] It is mentioned above that the lateral material guiding structure 32 is adjustable, therefore the distance between the powered roller 322 and the lateral guide rollers 321 will change, if the traditional belt or chain is used, it is easy to be too tight or too loose to provide power, therefore the movable adjusting member 323 in the embodiment comprises a hinge plate 3231 rotatably connected to the shaft head of the powered roller 322 or the lateral guide rollers 321, two adjacent hinge plates 3231 are connected through a movable wheel 3232, the movable wheel 3232 is connected with the shaft head of the powered roller 322 or the lateral guide rollers 321 through a belt, two hinge plates 3231 and a movable wheel 3232 are used to connect the belt, so that the angle between the two hinge plates 3231 can be automatically adjusted according to the gap between the powered roller 322 and the lateral guide rollers 321, so that the belt can always be tight and provide transmission effect for the lateral guide rollers 321 and the powered roller 322.
[0037] Although the spacing between the lateral guide rollers 321 and the power rollers 322 is stably adjusted by the above arrangement, the stability of the distal guide rollers is reduced by the arrangement of too many guide rollers.
