AI Technical Summary
In existing plate-type transmission chain structures, the connecting shaft serves the dual function of connecting the chain and installing the translation wheel, resulting in the shaft head being exposed and easily damaged. This reduces the chain's load capacity and safety, and cannot effectively prevent the load from being inserted into the upper support plate and causing damage or being hooked up, thus leading to accidents.
The connecting shaft that transmits tension through the connecting chain is separated from the spindle that mounts the translation wheel and the weighing shaft. The connecting shaft is fixed with an interference fit, and a side protective support plate is set to protect the translation wheel. A transition slope is formed on the upper load-bearing plate. This separation design improves structural stability and safety.
It improves the structural stability and safety performance of the plate conveyor chain, reduces the risk of shaft damage and impact from loads, extends the service life of the chain, and reduces maintenance costs.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of plate conveyor chains, and in particular to a plate split-shaft conveyor chain. Background Technology
[0002] The existing plate-type transmission chain structure is relatively simple. The connecting shaft serves a dual function of connecting the chain and acting as the wheel axle. This design results in the translating wheel and axle head being exposed outside the chain during operation. The rotation of the wheel forces the axle head to be positioned using snap rings, lacking axial preload. This frequently leads to wheel detachment and various axle breakages when subjected to lateral forces or obstructed by foreign objects during operation. The chain, which should be subject to rolling friction, becomes subject to sliding friction, reducing its load-bearing capacity. If not detected in time, this can cause the chain side plates to detach and break. The additional tension from sliding friction can sometimes break the connecting shaft or deform the chain, threatening normal safe production. The current structure and layout of this plate-type chain also mean that the upper load-bearing plate can only be flat or slightly concave, failing to effectively prevent the carried object from inserting into or damaging the upper load-bearing plate, causing chain jamming and accidents. Chains using this structure have a large surface area and are used in large quantities, resulting in high maintenance costs and time. Summary of the Invention
[0003] Purpose of the utility model: In order to overcome the shortcomings of the prior art, this utility model discloses a plate-type split-shaft conveyor chain. This structure separates the connecting shaft that transmits tension from the connecting chain from the spindle that installs the translation wheel and the weighing shaft, thereby improving the structural stability.
[0004] Technical solution: The plate-type split shaft conveyor chain disclosed in this utility model includes multiple chain side plates with adjacent ends overlapping and connected by a connecting shaft to form a chain structure. A translation wheel is provided in the middle of the outer side of the chain side plate, and an upper bearing plate is provided on the top of the chain side plate.
[0005] Furthermore, a side protective support plate is provided on the outer side of the chain side plate. The two ends of the side protective support plate are passed through by the connecting shaft and axially fixed by interference fit. The part of the side protective support plate corresponding to the translation wheel protrudes outward to form a protective side. The side of the protective side protrudes from the end of the connecting shaft.
[0006] Furthermore, the translation wheel is positioned between the side protection support plate and the chain side plate via a spindle.
[0007] Furthermore, the two connecting ends of the spindle are divided into a circle and a polygon, and the chain side plate and the side protective support plate are respectively provided with a circle hole and a polygon hole for insertion.
[0008] Furthermore, the two ends of the upper bearing plate in the transmission direction are inclined downward to form a transition slope.
[0009] Furthermore, a translation wheel is provided on each chain side plate or every other chain side plate in the chain structure.
[0010] Beneficial effects: Compared with the prior art, the advantages of this utility model are:
[0011] 1. This structure separates the connecting shaft that transmits tension through the connecting chain from the spindle that mounts the translation wheel and the weighing shaft, reducing the load on a single shaft. At the same time, the connecting shaft can be axially locked through an interference fit, improving structural stability.
[0012] 2. By setting side protective support plates, the translation wheels and the outer end of the connecting shaft can be protected, thereby improving the structural safety performance;
[0013] 3. Because the translation wheel is adjusted to the center, it creates a new space for the transition slope of the upper bearing plate. This allows the upper bearing plate to be free from the size limitations of the translation wheel, increasing the size of the transition slope, preventing foreign objects from getting caught, and reducing the horizontal impact of the load or foreign objects on the upper bearing plate. Attached Figure Description
[0014] Figure 1 This is a structural diagram of a single conveyor chain of this utility model;
[0015] Figure 2 This is a structural diagram of the overall conveyor chain of this utility model. Detailed Implementation
[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0017] like Figure 1 and 2 The plate-type split shaft conveyor chain shown includes multiple chain side plates 1 whose adjacent ends overlap and are connected by a connecting shaft 2 to form a chain structure. A translation wheel 3 is provided in the middle of the outer side of the chain side plate 1, and an upper bearing plate 4 is provided on the top of the chain side plate 1.
[0018] In the conveyor chain, the chain connecting shaft, which bears the load and transmits tension, is decomposed into a spindle that supports the chain and the weight of the load and is used to install the translation wheel, and a connecting shaft 2 that independently transmits tension. The two shafts are designed separately, and each performs its own function after separation, which greatly extends the service life of this type of chain.
[0019] The chain side plate 1 is provided with a side protective support plate 5 on its outer side. The two ends of the side protective support plate 5 are passed through by the connecting shaft 2 and are axially fixed by interference fit, which effectively prevents the chain side plate from coming off.
[0020] The side protective support plate 5 protrudes outward at the part corresponding to the translation wheel 3 to form a protective side. The side of the protective side protrudes from the end of the connecting shaft 2. This protective side can effectively protect the connecting shaft 2 and the translation wheel 3, ensuring that the device can operate safely and efficiently.
[0021] The translation wheel 3 is located between the side protective support plate 5 and the chain side plate 1 via a spindle 6. The two connecting ends of the spindle 6 are circular and polygonal. The chain side plate 1 and the side protective support plate 5 are respectively provided with circular holes and polygonal holes for insertion. While fixing the translation wheel 3, the spindle does not rotate, making disassembly and assembly very convenient.
[0022] The upper bearing plate 4 is inclined downward at both ends in the transmission direction to form a transition slope 401. The translation wheel 3 moves to the middle of the chain, which creates conditions for the lowering of the head and tail of the upper bearing plate 4. The change in physical shape effectively decomposes and weakens the force of various external forces in the transmission direction on the upper bearing plate of the chain, and reduces damage to the upper bearing plate.
[0023] On the chain structure, a translation wheel 3 is provided on each chain side plate 1 or every other chain side plate 1, such as... Figure 2 As shown, a translation wheel 3 is provided on the chain structure at intervals of one chain side plate 1.
