Description

Technical Field

[0001] The utility model belongs to the technical field of circulating conveying chains, and in particular relates to a core shaft circulating transmission mechanism. Background Art

[0002] Chain conveyors use chains as traction and carriers to transport materials. The chains can be ordinary sleeve roller conveyor chains or other special chains (such as accumulation chains and double-speed chains). Chain conveyors have large conveying capacity and are mainly used to transport pallets, large turnover boxes, etc. The conveyor chain has various structural forms and a variety of accessories, which are easy to realize accumulation and conveying. It can be used as an assembly production line or as a material storage and conveying. In the prior art, the chain conveying mechanism needs to be lubricated regularly during use to ensure the smoothness of the chain conveying mechanism. However, most of the prior art uses manual lubrication of the chain, which is not only troublesome to operate, but also requires frequent manual demoulding.

[0003] To this end, a chain circulation conveying mechanism with a bulletin number of "CN216402862U" relates to the technical field of chain conveying mechanisms, including a main body and a chain, wherein oil boxes are fixedly arranged on both sides of the chain, an oil storage cavity is provided inside the oil box, and a sponge friction strip is provided inside the oil box and on one side close to the chain. The utility model is provided with oil boxes on both sides of the chain, and an oil storage cavity is provided inside the oil box. The staff injects lubricating oil into the oil storage cavity, and then gradually immerses the lubricating oil into the sponge friction strip under the action of the oil-absorbing cotton strip. When the chain is conveyed in a circular manner, the chain and the sponge friction strip are in contact with each other, and then the lubricating oil inside the sponge friction strip can be well transferred to the outer surface of the chain at this time, thereby playing a role in lubricating the chain, effectively avoiding the need for the staff to frequently apply lubricating oil to the chain, greatly reducing the labor intensity of the staff, and effectively improving the fluency of the chain conveying process.

[0004] However, for the above-mentioned chain circulation conveying mechanism, although the chain is driven to perform circular conveying under the action of the rotating shaft and two sets of sprockets, and the top of the chain is connected to multiple sets of connecting rods and moving blocks, which can perform circular conveying of external products, there are still the following obvious defects during use: in the process of the above-mentioned chain driving the workpieces on the moving plate to move at a uniform speed, since the workpieces are limited by the limiting columns, during the process of conveying steel, the chain will be thrown out of the moving plate due to the fast rotating conveying speed, and it will be easy to get stuck on the inner side of the limiting column when taking materials.

The corresponding end of the workpiece clamp is provided with a clamping groove with an arc surface for clamping the mandrel workpiece, which can realize the clamping of the mandrel workpiece by sliding the workpiece clamp and limiting the direction of the workpiece by the vertical rod.

[0010] Preferably, the bottom sides of both ends of the carrier plate are located at the corresponding upper ends of the strip vertical plates for supporting the carrier plate during transportation, so as to maintain the stability of the carrier plate when transporting the workpiece.

[0011] Preferably, the conveying front end transmission link of the bending plate chain is connected with a transmission optical axis, and the conveying end transmission link of the bending plate chain is connected with a linear rotating shaft. The transmission optical axis and both ends of the linear rotating shaft are movably transmitted to the outside of both ends of the strip vertical plate, so as to drive the bending plate chain to rotate in a cycle and continuously convey the core shaft workpiece.

[0012] Preferably, a reducer is transmission-connected on the rotating shaft of the servo motor, and the reducer is fixed on the outside of one end of the strip vertical plate, and the rotating shaft of the reducer is transmission-connected to one end of the linear rotating shaft, driving the bending plate chain to rotate and driving the carrier plate to move in a cycle, so as to realize the transportation of the core shaft workpiece.

[0013] Preferably, one side of the two strip uprights is provided with an L-shaped mounting plate for mounting and fixing the strip uprights, which is used to mount the annular conveying mechanism on an external fixed bracket to facilitate docking with other processing stations to form a conveying system.
