Description

Technical Field

[0001] This utility model belongs to the field of automated conveying technology, and in particular relates to a self-deforming convex conveyor belt. Background Technology

[0002] With the development of automated production and logistics technologies, higher requirements have been placed on automated conveying systems. These systems not only need to be able to adapt to objects of different shapes and sizes, but also need to be able to automatically adjust their direction and posture during the conveying process, especially in application scenarios such as rapid sorting and directional conveying of irregular objects.

[0003] Currently, the conveyor belts used in existing automated conveying systems are generally designed with a fixed shape. During the transportation of objects on the conveyor belt, the direction adjustment and convergence are mainly achieved with the assistance of external guide rails or baffles. As a result, automated conveying systems generally suffer from problems such as high equipment complexity, large space occupation, and poor adaptability. They are particularly limited when dealing with objects of diverse shapes and postures.

[0004] Furthermore, especially in scenarios where the posture of objects needs to be adjusted during the conveying process, traditional conveyor belts require additional mechanical posture adjustment equipment or manual operation stations, which not only reduces production efficiency but also increases operating costs.

[0005] For example, multi-level guide rails are added to both sides of some conveyor belts, and the objects are guided to adjust their direction through corresponding mechanical structures. Although the above method can achieve the positioning and convergence of objects on the conveyor belt, the adjustment process is complicated and the equipment has low flexibility, making it unsuitable for rapidly changing industrial production scenarios.

[0006] In addition, some conveyor belts have added vibration mechanisms to adjust the direction of objects by vibration. However, vibration also poses a risk of damaging the objects and is accompanied by a lot of noise when the vibration mechanism is running, so its application range is relatively limited.

[0035] The following describes a single use of this utility model with reference to the accompanying drawings:

[0036] In this embodiment, the lengths of the first horizontal elongated hole 17 and the second horizontal elongated hole 18 are twice the lengths of the first vertical elongated hole 14 and the second vertical elongated hole 20. When the middle counterweight 4 is suspended, the angle between the upper surfaces of the left and right transition blocks 7 and 8 and the horizontal plane is 26.565°. The side surfaces of the middle counterweight 4, the left support block 5, and the right support block 6 are all provided with an inward inclination angle of 14°. The driving wheel 2, the driven wheel 3, the first transition pin 21, the second transition pin 22, the third transition pin 23, and the fourth transition pin 24 are all made of 42CrMo alloy steel. The middle counterweight 4 is made of Q235 carbon steel. The left support block 5, the right support block 6, the transition connecting rod 25, the first transition pin 26, and the second transition pin 27 are all made of 6061-T6 aluminum alloy.

[0037] In practical applications, when the middle counterweight 4 is located on the upper layer of the conveyor belt body 1 and is suspended, it will automatically sink under the action of gravity, thereby realizing the automatic deformation of the chain link unit. At this time, a height difference will be formed between the middle counterweight 4 and the left support block 5 and the right support block 6 on both sides. The conveyor belt body 1 will form a concave state at the center line. When the object is transported on the conveyor belt body 1, it will also be caused by gravity to automatically roll and converge towards the center line of the conveyor belt body 1, achieving efficient convergence and also enabling the object to automatically adjust its posture on the conveyor belt body 1. Then, the object can be stably transported to the designated position.

[0038] When the intermediate counterweight 4 is positioned at the second driving wheel annular rib 31 of the driving wheel 2 and the second driven wheel annular rib 37 of the driven wheel 3, the intermediate counterweight 4 will be supported by the second driving wheel annular rib 31 and the second driven wheel annular rib 37, at which point the height difference between the intermediate counterweight 4 and the left support block 5 and the right support block 6 on both sides will disappear. When the intermediate counterweight 4 is located at the lower layer of the conveyor belt body 1, gravity will generate a reverse pulling force, ensuring that the intermediate counterweight 4 and the left support block 5 and the right support block 6 on both sides are always at the same horizontal height. That is to say, when the conveyor belt body 1 rotates around the driving wheel 2 and the driven wheel 3, it will only automatically deform to achieve automatic convergence and attitude adjustment of the object when it is located at the upper layer of the conveyor belt body 1 and in a suspended state; the conveyor belt body 1 at other positions is in a non-deformable state.
