AI Technical Summary
In the existing plate transmission chain structure, the coupling shaft simultaneously assumes the dual role of the coupling chain transmitting tension and installing the translation wheel, resulting in the exposure of the shaft head and lack of axial preloading force, which is prone to wheel drop, sliding friction and chain breakage. Affects production safety.
The coupling shaft that transmits tension from the coupling chain is separated from the mounting translation wheel and mandrel. Through the design of the side protective support plate and multi-shaped mandrel, the function of the coupling shaft is separated to increase structural stability and safety.
It improves structural stability and safety performance, reduces the load of a single shaft body, prevents foreign matters from being inserted and impacted, extends the service life of the chain, and reduces maintenance costs and time.

Abstract
Description
Technical Field
[0001] The invention relates to the field of plate type conveyor chains, in particular to a plate type split-axis conveyor chain. Background Art
[0002] The existing plate transmission chain has a relatively simple structure. The connecting shaft plays a dual role of connecting the chain and serving as the wheel spindle. Its design causes the translation wheel and the shaft head to be exposed outside the chain in actual work. The rotation of the wheel causes the shaft head to be positioned only by a retaining spring, etc., and lacks axial preload. As a result, the wheel often falls off and various shaft breaks occur after being blocked by lateral force or foreign objects during operation. The chain, which was originally in rolling friction motion, becomes sliding friction, reducing the load capacity of the chain. If it is not discovered in time, it will cause the side plate of the chain to fall off and break the chain. The additional tension caused by sliding friction sometimes breaks the connecting shaft or deforms the chain. It threatens normal safe production. The current structure and layout of this plate chain also cause the upper bearing plate to be only flat or slightly concave, which cannot effectively prevent the loaded object from being inserted into the upper bearing plate and damaging it or hooking up the upper bearing plate, causing the chain to be blocked and cause accidents. However, the area and number of chains using this structure are huge, so the maintenance cost and time are relatively large. Summary of the invention
[0003] Purpose of the invention: In order to overcome the shortcomings of the background technology, the present invention discloses a plate-type split-axis conveyor chain, which separates the connecting shaft for transmitting tension of the connecting chain from the core shaft for installing the translation wheel and weighing, thereby improving the structural stability.
[0004] Technical solution: The plate-type split-axis conveyor chain disclosed in the present invention comprises a plurality of chain side plates whose adjacent ends overlap and are connected through a connecting shaft to form a chain structure, a translation wheel is arranged in the middle of the outer side of the chain side plate, and an upper bearing plate is arranged on the top of the chain side plate.
[0005] Furthermore, a side protection support plate is provided on the outer side of the chain side plate, and both ends of the side protection support plate are passed through by the connecting shaft and are axially fixed by interference fit. The part of the side protection support plate corresponding to the translation wheel protrudes outward to form a protective side edge, and the side portion of the protective side edge protrudes from the end of the connecting shaft.
[0006] Furthermore, the translation wheel is arranged between the side protection support plate and the chain side plate through a core shaft.
[0007] Furthermore, the two connecting ends of the core shaft are divided into circular and polygonal shapes, and the chain side plates and side protection support plates are respectively provided with circular holes and polygonal holes for their insertion.
[0008] Furthermore, both ends of the upper carrying plate in the transmission direction are inclined downward to form transition slopes.
[0009] Furthermore, a translation wheel is provided on each chain side plate or every other chain side plate on the chain structure.
[0010] Beneficial effects: Compared with the prior art, the advantages of the present invention are: 1. This structure separates the connecting shaft that transmits the tension of the connecting chain from the mandrel for installing the translation wheel and weighing, reducing the load on a single shaft. At the same time, the connecting shaft can be axially locked through interference fit to improve structural stability. 2. By setting up the side protection support plate, the translation wheel and the outer end of the connecting shaft can be protected to improve the structural safety performance; 3. Since the translation wheel is adjusted to the middle, a space is created for the transition slope of the upper load-bearing plate, so that the upper load-bearing plate is not limited by the size of the translation wheel. The size of the transition slope can be increased to prevent foreign objects from getting caught, and the impact of the load or foreign objects on the upper load-bearing plate in the horizontal direction is reduced. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 It is a structural diagram of a single conveyor chain of the present invention; Figure 2 It is the structural diagram of the overall conveying chain of the present invention. DETAILED DESCRIPTION
[0012] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.
[0013] like Figure 1 and 2 The plate-type split-axis conveyor chain shown includes a plurality of chain side plates 1 whose adjacent ends overlap and are connected through a connecting shaft 2 to form a chain structure. A translation wheel 3 is arranged in the middle of the outer side of the chain side plate 1, and an upper bearing plate 4 is arranged on the top of the chain side plate 1.
[0014] The chain coupling shaft that carries and transmits tension in the conveyor chain is decomposed into a core shaft used to support the weight of the chain and the load and to install the translation wheel, and a coupling shaft 2 that independently transmits tension. The two shafts are designed to be split, and each performs its own function after being separated, which greatly extends the service life of the chain.
[0015] A side protection support plate 5 is provided on the outer side of the chain side plate 1. The two ends of the side protection support plate 5 are passed through by the connecting shaft 2 and are axially fixed by interference fit, so as to effectively prevent the chain side plate from falling out.
[0016] The side protection support plate 5 protrudes outward at the position corresponding to the translation wheel 3 to form a protection side edge, and the side portion of the protection side edge protrudes from the end of the connecting shaft 2. The protection side edge can effectively protect the connecting shaft 2 and the translation wheel 3 to ensure that the device can operate safely and efficiently.
[0017] The translation wheel 3 is arranged between the side protection support plate 5 and the chain side plate 1 through the core shaft 6. The two connecting ends of the core shaft 6 are divided into circular and polygonal shapes. The chain side plate 1 and the side protection support plate 5 respectively have corresponding circular holes and polygonal holes for their insertion. The translation wheel 3 is fixed without the core shaft rotating, and disassembly and assembly are very convenient.
[0018] The two ends of the upper bearing plate 4 in the transmission direction are tilted downward to form a transition slope 401, and the translation wheel 3 moves to the middle of the chain, creating 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 various external forces exerted on the bearing plate on the chain in the conveying direction, thereby reducing damage to the upper bearing plate.
[0019] On the chain structure, a translation wheel 3 is arranged on each chain side plate 1 or every other chain side plate 1. Figure 2 As shown, a translation wheel 3 is arranged on the chain structure with a chain side plate 1 spaced apart.
