Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of logistics transportation, and more specifically, to a double-layer circulating belt line for logistics transportation. Background Art
[0002] A double-layer circulating belt line is a conveying device specifically used for logistics and production automation. It consists of two layers of belts arranged in parallel. Each layer of belt can operate independently to achieve higher conveying efficiency and flexibility. This double-layer circulating belt line is usually driven by one or more driving devices to make the upper and lower layers of belts operate simultaneously or alternately. Items or products can be placed on the upper belt and conveyed to the target position through movement. On the lower belt, it can be used to recycle, return, or further process items. This device is widely used in various industries, such as logistics warehousing, production manufacturing, postal express, etc.
[0003] Some existing double-layer belt lines have the function that the height and spacing between the two layers of belt lines can be adjusted. This means that different types or sizes of items can be conveyed to different positions respectively or combined into one logistics process, which has high flexibility in material sorting and organization. However, when the spacing between the two layers of belt pulleys is too large, the impact force on the item when it falls from the upper belt to the lower belt increases, and the item is easily damaged.
[0004] Therefore, a double-layer circulating belt line for logistics transportation is proposed to solve the above problems. Content of the Utility Model

[0031] Embodiment:
[0032] Please refer to Figure 1-2, A double - layer circulating belt conveyor for logistics transportation, including an adjustment bracket 1. The inner ends of the adjustment bracket 1 are respectively installed with an upper - layer belt 2 and a lower - layer belt 3. And a base 4 is arranged on one side of the adjustment bracket 1. A driving component 5 and a buffer component 6 are respectively arranged on the base 4. The buffer component 6 includes a pair of symmetrically arranged mounting frames 601. A pair of limiting rods 602 are rotatably connected to the inner ends of the mounting frames 601. A crawler 607 is installed at the outer ends of the limiting rods 602. A group of buffer plates 606 are installed at the outer ends of the pair of crawlers 607.
[0033] The double - layer circulating belt conveyor is a conveying device specifically used for logistics and production automation. It consists of two layers of belts arranged in parallel. Each layer of belt can operate independently to achieve higher conveying efficiency and flexibility. This double - layer circulating belt conveyor is usually driven by one or more driving devices to make the upper and lower layers of belts run simultaneously or alternately. Items or products can be placed on the upper - layer belt and transported to the target position through movement. And on the lower - layer belt, it can be used for recycling, returning or further processing of items. This device is widely used in various industries, such as logistics warehousing, manufacturing, postal express, etc.
[0034] In this solution, a hydraulic device connected to the upper - layer belt 2 and the lower - layer belt 3 is installed inside the adjustment bracket 1. When it is necessary to adjust the heights of the upper - layer belt 2 and the lower - layer belt 3, the hydraulic pump in the hydraulic device is started to provide hydraulic pressure to the hydraulic cylinder. The hydraulic cylinder starts to expand and contract, pushing the upper - layer belt 2 and the lower - layer belt 3 to slide up or down at the inner ends of the adjustment bracket 1. By controlling the hydraulic pressure provided by the hydraulic pump, the heights of the upper - layer belt 2 and the lower - layer belt 3 can be precisely adjusted, changing the spacing between the upper - layer belt 2 and the lower - layer belt 3. This adjustment can be flexibly adjusted according to the size of the item, conveying requirements or other factors. Once the height adjustment is completed, the upper - layer belt 2 and the lower - layer belt 3 can start running and move at the set speed and direction to achieve the conveying of items.
[0035] The object first moves on the upper - layer belt 2 and is transported in the direction of the buffer component 6. Finally, when the object reaches the edge of the upper - layer belt 2, it will fall from the edge to the lower - layer belt 3 below. Then the lower - layer belt 3 conveys the item. During the process of the item falling, it will pass through multiple buffer plates 606. The multiple buffer plates 606 are made of flexible materials. An item with a certain weight will push the multiple buffer plates 606 to deform and finally fall onto the lower - layer belt 3. During this process, the falling speed of the item is greatly reduced, effectively reducing the impact of the item on the lower - layer belt 3, thus playing a protective role for the item.
[0036] Please refer to Figure 1-3, a sprocket wheel 603 is fixedly connected to the outer end of the limiting rod 602. The buffer assembly 6 further includes a pair of chains 604. The pair of sprocket wheels 603 are drivingly connected through the chains 604. The driving assembly 5 includes a servo motor 501. The servo motor 501 is installed on the base 4, and the output end of the servo motor 501 is fixedly connected to a rotating rod 502. One end of the rotating rod 502 away from the servo motor 501 is rotatably connected to the base 4. A pair of symmetrically arranged first bevel gears 503 are fixedly connected to the outer end of the rotating rod 502. One end of each of the pair of limiting rods 602 on the lower side is fixedly connected to a second bevel gear 605. The second bevel gear 605 is meshingly connected to the first bevel gear 503. The upper belt 2 is located on one side of the pair of mounting brackets 601. One end of the lower belt 3 extends between the pair of mounting brackets 601. The ends of the two buffer plates 606 close to each other are arranged in a staggered manner.
[0037] During the transportation of the article, the user starts the servo motor 501 to drive the rotating rod 502 to rotate. The pair of first bevel gears 503 are driven to rotate through the rotating rod 502. Then, the pair of second bevel gears 605 are driven to rotate synchronously in opposite directions through the first bevel gears 503. The limiting rods 602 on the lower side are driven to rotate through the second bevel gears 605. Then, under the driving action of the sprocket wheels 603 and the chains 604, multiple limiting rods 602 rotate synchronously. Through the rotation of the multiple limiting rods 602, a pair of crawlers 607 are driven to rotate slowly in opposite directions, and then the two buffer plates 606 are driven to move synchronously in a crossed form. During the movement of the multiple buffer plates 606, the articles falling from the upper belt 2 can be continuously and stably transported onto the lower belt 3. Even if the lighter articles cannot push the buffer plates 606, they can stay on the surface of the buffer plates 606 and move downward with the buffer plates 606 and finally fall onto the lower belt 3. Since the buffer plates 606 are made of flexible materials, when the buffer plates 606 move downward and touch the lower belt 3, they will deform, so they can directly move from the upper end of the lower belt 3 to the lower side of the lower belt 3 without hindering the operation of the lower belt 3. Similarly, the buffer plates 606 will not hinder the lower belt 3 during the height adjustment of the lower belt 3.
[0038] Working principle:
[0039] When the user needs to adjust the heights of the upper belt 2 and the lower belt 3, the hydraulic pump in the hydraulic device inside the adjusting bracket 1 is started to provide hydraulic pressure to the hydraulic cylinder. The hydraulic cylinder starts to extend and retract, pushing the upper belt 2 and the lower belt 3 to slide up or down at the inner end of the adjusting bracket 1. By controlling the hydraulic pressure provided by the hydraulic pump, the heights of the upper belt 2 and the lower belt 3 can be precisely adjusted, changing the distance between the upper belt 2 and the lower belt 3. Once the height adjustment is completed, the upper belt 2 and the lower belt 3 can start running and move in accordance with the set speed and direction to achieve the transportation of items. The object first moves on the upper belt 2 and is transported in the direction of the buffer assembly 6. Finally, when the object reaches the edge of the upper belt 2, it will fall from the edge to the lower belt 3 below, and then the lower belt 3 transports the item. During the process of the item falling, it will pass through multiple buffer plates 606. An item with a certain weight will push the multiple buffer plates 606 to deform and finally fall onto the lower belt 3. During this process, the falling speed of the item is greatly reduced, effectively reducing the impact of the item on the lower belt 3, thereby playing a protective role for the item. During the transportation of the item, the user can start the servo motor 501 to drive the rotating rod 502 to rotate. The rotating rod 502 drives a pair of first bevel gears 503 to rotate, and then through the first bevel gears 503, a pair of second bevel gears 605 are driven to rotate in opposite directions synchronously. The second bevel gears 605 drive the limiting rods 602 located on the lower side to rotate. Then, under the driving action of the sprockets 603 and the chain 604, the multiple limiting rods 602 rotate synchronously. Through the rotation of the multiple limiting rods 602, a pair of crawlers 607 are driven to rotate slowly in opposite directions, and then the two groups of buffer plates 606 are driven to move synchronously in a crossed form. During the movement of the multiple buffer plates 606, the items falling from the upper belt 2 can be continuously and smoothly transported to the lower belt 3. When the buffer plate 606 moves downward and touches the lower belt 3, it will deform and directly move from the upper end of the lower belt 3 to the lower side of the lower belt 3 without hindering the operation of the lower belt 3.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
