Description

Technical Field

[0001] The utility model relates to the technical field of conveyor chains, in particular to a lightweight sleeve pin anti-rotation conveyor chain. Background Art

[0002] Chain is a commonly used and important product in conveying and rotating equipment. The sleeve of the chain is matched with the roller and the pin during production. When the existing chain is in use, the sleeve will produce irregular rotation under the rotation of the roller, and the pin position is also prone to rotation. In order to limit the rotation of the pin, a chain plate connecting the two pins is usually set on the outside of the chain. However, the overall weight is relatively large. The overall weight of the chain will increase a lot during use. For chain application environments with relatively high weight requirements, the existing chains cannot meet the use requirements. Utility Model Content

[0003] The purpose of the utility model is to provide a lightweight sleeve pin anti-rotation conveyor chain, which has an overall lighter weight, and the internal sleeve and pin can both achieve the anti-rotation function. The outer baffle is designed in a welding manner, which has a smaller volume and a lighter weight. The overall production cost during use is lower, and at the same time it can ensure that the chain has a stronger bearing capacity and runs more smoothly. When welding the baffle, the positioning accuracy is better and the welding coordination operation is more convenient.

[0004] The technical solution of the utility model is as follows:

[0005] A lightweight sleeve pin anti-rotation conveyor chain comprises a plurality of inner chain links and outer chain links, the inner chain links comprising inner chain plates, sleeves and rollers, the inner chain plates being respectively mounted at both ends of the sleeve, the rollers being sleeved on the sleeves and being located between the two inner chain plates, and characterized in that an anti-rotation matching limit groove is provided at the matching position between the outer side of the sleeve and the inner chain plate; the outer chain links comprise outer chain plates, pins and baffles, the baffles being connected to the outer chain plates by welding, one side of the baffles being matched with the limiting grooves provided on the pins, the area of ​​the outer end face of the baffles being smaller than the area of ​​the outer end face of the pins, and the outer side of the rollers being beyond the plane where the upper and lower end faces of the outer chain plates are located.

[0006] Furthermore, a position identification line is provided at the matching position between the outer end surface of the outer link plate and the baffle.

[0007] Furthermore, the length of the baffle is the same as the diameter of the pin shaft.

[0008] Beneficial effects of the utility model:

[0009] The utility model has a lighter overall weight, and the internal sleeve and pin shaft can both achieve the function of anti-rotation. The outer baffle is designed in a welding manner, which has a smaller volume and a lighter weight. The overall production cost during use is lower. At the same time, it can ensure that the chain has a stronger bearing capacity and runs more smoothly. When welding the baffle, the positioning accuracy is better and the welding coordination operation is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] like Figure 1 and Figure 2 As shown, a lightweight sleeve pin anti-rotation conveyor chain includes a plurality of inner links and outer links. The inner link includes an inner chain plate 1, a sleeve 2, and a roller 3. The inner chain plates 1 are respectively mounted at both ends of the sleeve 2. The roller 3 is sleeved on the sleeve 2 and is located between the two inner chain plates 1. The outer side of the sleeve 2 is provided with an anti-rotation matching limit groove at the matching position with the inner chain plate 1, which can effectively prevent the sleeve 2 from rotating during use, avoid unnecessary wear during use, and improve the safety during operation. The outer link includes an outer chain plate 4, a pin 5, and a baffle 6. The baffle 6 is connected to the outer chain plate 4 by welding. One side of the baffle 6 is matched with the limit groove provided on the pin 5. The area of ​​the outer end surface of the baffle 6 is smaller than the area of ​​the outer end surface of the pin 5, so that the weight of the baffle structure is lighter, and the weight of the chain as a whole is effectively reduced. The outer side of the roller 3 exceeds the plane where the upper and lower end surfaces of the outer link plate 4 are located, ensuring that the roller will affect the sleeve during rotation during use, thereby improving the overall stability during operation. Its overall weight is lighter, and the internal sleeve and pin shaft can both achieve the function of anti-rotation. The outer baffle is designed by welding, which is smaller in size and lighter in weight. The overall production cost is lower during use, and at the same time, it can ensure that the chain has a stronger bearing capacity and runs more smoothly. When welding the baffle, the position accuracy is better and the welding coordination operation is more convenient.

[0014] Preferably, a position marking line is provided at the matching position between the outer end surface of the outer link plate 4 and the baffle 6, which is more convenient when placing the welding position, can effectively improve the convenience during welding, and ensure the position matching accuracy during welding.

[0015] As a preferred solution, the position matching mark on the baffle 6 can be set at the side position to improve the position matching accuracy during welding and make it easier to perform accurate observation.

[0016] Preferably, the length of the baffle 6 is the same as the diameter of the pin shaft 5, so that the matching safety force of the anti-rotation position is stronger and the matching protection effect is better.

[0017] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements or substitutions can be made without departing from the principles of the present invention. These improvements or substitutions should also be regarded as the protection scope of the present invention.
