Description

Technical Field

[0001] The invention relates to the technical field of chains, in particular to a mesh belt conveyor chain with turning and changing diameters. Background Art

[0002] The mesh belt conveyor chain generally adopts standard chain transmission, which has stable operation and smooth travel, can effectively reduce vibration and noise, and can achieve high-precision synchronous transmission. It is suitable for large and heavy transmission, has strong power, relatively small force on the mesh surface, strong load-bearing capacity and tensile strength, can withstand heavier pressure and tension, has good turning performance, and can achieve 180-degree turning. However, the diameter of the existing mesh surface structure of the mesh belt conveyor chain cannot be changed during the turning process, that is, the conveying width cannot be changed, resulting in some glass products at the edge being thrown out of the chain due to centrifugal force during the conveying of some high-temperature glass products. In addition, since the position of the objects on the chain cannot be relatively changed, the objects on the entire chain are relatively messy, which is not convenient for subsequent sorting and collection of objects. How to control the displacement of objects relative to the mesh belt during the turning process of the mesh belt conveyor chain and control the turning and changing the diameter to collect and concentrate objects is the object of study for technical personnel in this field. Summary of the invention

[0003] The invention provides a mesh belt conveyor chain with a turning and changing diameter, aiming to solve the problem of object collection and centrifugal throwing out caused by the inability of a traditional mesh belt conveyor chain to change diameter during transmission.

[0004] The belt conveyor chain is a belt conveyor chain with a plurality of movable parts, each of which has a plurality of movable parts, and the movable parts are connected to the movable part by a plurality of movable parts. The chain conveying links are connected end to end, and the first variable diameter mesh belt conveyor chain link includes a first guide shaft and a second guide shaft. The first guide shaft is connected to the first guide piece, the first variable diameter chain piece, the second variable diameter chain piece, the third variable diameter chain piece, and the fourth guide piece in sequence, and the second guide shaft is connected to the second guide piece, the first variable diameter chain piece, the fourth variable diameter chain piece, the third variable diameter chain piece, and the fifth guide piece in sequence; the second variable diameter chain piece is connected with the first variable diameter chain piece and the third variable diameter chain piece at a connection point provided with an integrated second variable diameter protrusion; the first variable diameter chain piece is connected with the second guide piece and the fourth variable diameter chain piece at a connection point provided with an integrated first variable diameter protrusion; the third variable diameter chain piece is connected with the fourth variable diameter chain piece and the fifth guide piece at a connection point provided with an integrated third variable diameter protrusion, and the turning diameter of the first variable diameter mesh belt conveyor chain link is adjusted by the above three variable diameter protrusions. This kind of mesh belt conveyor chain with turning and changing diameter adopts roller guide chain to cooperate with conveying guide rail, which ensures that the whole mesh belt conveyor chain can run along the set track to ensure running stability, and the upper side of the roller guide chain connects the mesh belt conveyor chain to form a layered design of upper and lower structures to realize that the conveying width of the mesh belt conveyor chain is not restricted and can be changed. Further, through the first variable diameter mesh belt conveyor chain and the second variable diameter mesh belt conveyor chain and the third variable diameter mesh belt conveyor chain respectively located on the outside of the two outer chain plates, the three variable diameter mesh belt conveyor chains adjust the conveying width of the whole mesh belt conveyor chain. The outer edges of the second variable diameter mesh belt conveyor chain and the third variable diameter mesh belt conveyor chain located on both sides are respectively limited by the sixth guide plate and the third guide plate. In the process of turning and changing diameter, the objects are driven to move closer to the first variable diameter mesh belt conveyor chain in the middle to realize the ability to collect the center of the objects, and the change in the angle between the three variable diameter protrusions during the turning process adjusts the turning diameter of the first variable diameter mesh belt conveyor chain link. The structure is simple and the performance is reliable.

Generally, a width change with a large inlet and a small outlet is formed during the turning process, thereby achieving the technical purpose of bringing the objects closer to the middle, and also avoiding the problem of throwing out due to excessive rotation speed.

[0006] The first guide shaft and the second guide shaft are simultaneously connected to the third guide plate and the second ends of the sixth variable diameter chain plate arranged horizontally, ensuring that the distance between the first guide shaft and the second guide shaft does not change, so that the first guide shaft and the second guide shaft can move synchronously with the entire mesh belt conveyor chain to improve operation stability.

The positioning hole cooperates to connect the first guide shaft, and the first slide groove cooperates to connect the second guide shaft. That is, the first guide shaft ensures the positioning of the first guide plate, the fourth guide plate, the second guide plate and the fifth guide plate, and the first slide groove cooperates to connect the second guide shaft so that the first guide plate, the fourth guide plate, the second guide plate and the fifth guide plate are offset relative to the second guide shaft, so as to adjust the angle between the three variable diameter protrusions of the first variable diameter mesh belt conveyor chain during the turning process, so as to achieve the technical purpose of synchronous change of turning radius.
