After the connection, the connecting boss 12 can perform a certain axial rotation around the articulated sleeve 16. Pin connecting holes 13 are provided on the inner side of the outer convex shaft seat 9 and the side of the connecting boss 12. The pin connecting hole 13 on the side of the connecting boss 12 is an interference setting with a hole diameter larger than the diameter of the knurled pin 14. A knurled pin 14 is provided inside the pin connecting hole 13. The knurled pin 14 passes through the connecting boss 12 and is inserted into the middle of the outer convex shaft seat 9. Two adjacent conveying guide seats 6 are connected by the knurled pin 14. There is a movable gap at the connection point, which is a movable setting. This chain plate mechanism 2 is suitable for a screw machine with a radius that can be extended from 160mm to an infinite radius and can be lifted from a height of 60CM to any required size height.
[0032] In order to carry and transport materials, the conveying chain plate 7 is fixed to the top of the conveying guide seat 6. Chain plate engaging grooves 19 are provided on the two connecting sides of the conveying chain plate 7. The two chain plate engaging grooves 19 are interference set, and a movable gap is left at the connection. The two adjacent conveying chain plates 7 are movably engaged with each other through the chain plate engaging grooves 19. When the conveying guide seat 6 is turned, the movable gap can facilitate the turning and conveying of the conveying chain plate 7. The top of the conveying chain plate 7 is fixed with anti-slip soft rubber 17.

The guide grooves 3 on both sides correspond to the conveying and return chain plate mechanisms 2 respectively. The guide grooves 3 are adapted to the conveying guide seat 6. The conveying guide seat 6 is movably engaged with the inner side of the guide groove 3. The side of the conveying guide seat 6 is provided with a first guide bearing 8 and a second guide bearing 10. One conveying guide seat 6 can be equipped with four or two bearings, which can be selected or assembled in any combination according to the weight of the conveyed object.

The conveying guide seat 6 is movable on the upper part of the conveying track 1 through the first guide bearing 8 and the second guide bearing 10. When steering conveying is performed, the steering conveying of the conveying chain plate 7 can be achieved through the bearing support. When the conveying chain plate 7 is turned, the two sets of guide structures are set to provide stable guiding support for the conveying chain plate 7, so that the conveyor can work more smoothly and turn more flexibly when conveying objects, and has the advantages of safety, reliability, low noise, and less wear.
[0035] In order to improve the service life of the conveyor track 1, wear-resistant strips 4 and guide pads 5 are respectively arranged on the upper part and the inside of the conveyor track 1. The wear-resistant strips 4 and the guide pads 5 are both pads made of ultra-high molecular self-lubricating material. Two groups of guide pads 5 are arranged. The two groups of guide pads 5 are respectively installed in the inside of the two guide rail grooves 3. The number of each group of guide pads 5 is two. The two guide pads 5 are respectively fixed on the two sides of the inside of the guide rail groove 3. The guide pads 5 are supported on the side where the conveyor track 1 connects with the second guide bearing 10. The number of wear-resistant strips 4 is two. The two wear-resistant strips 4 are respectively fixed on the two sides of the upper part of the conveyor track 1. The wear-resistant strips 4 are supported on the side where the conveyor track 1 connects with the first guide bearing 8. The contact side of the conveyor track 1 and the bearing can be protected by the support protection of the ultra-high molecular self-lubricating pads. Soft contact is adopted between the guide structures to reduce the working wear between the structures.
[0036] Working principle or structural principle, when working, the material is placed on the upper part of the conveying chain plate 7, and the material contacts the anti-slip soft rubber 17 on the upper part of the conveying chain plate 7, so that the material stays stably on the upper part of the conveying chain plate 7, and several conveying guide seats 6 are connected to each other to form a flexible conveying chain. Under the drive of the conveyor motor, the driving sprocket on the upper part of the conveyor rotates, and the tooth groove on the upper part of the driving sprocket is engaged with the outer convex shaft seat 9 on the side of the conveying guide seat 6. When the driving sprocket rotates, the conveying guide seat 6 can be driven to move by pushing the outer convex shaft seat 9, and the moving conveying guide seat 6 drives the material on the upper part of the conveying chain plate 7 to move. When turning, the first guide bearing 8 on the side of the conveying guide seat 6 contacts the wear-resistant strip 4 on the upper part of the conveying track 1, and the second guide bearing 10 located on the lower side contacts the guide pad strip 5 on the upper part of the conveying track 1. Under the bending guiding action of the conveying track 1, the two adjacent conveying guide seats 6 rotate around the hinged sleeve 16, and the steering operation is completed under the support and guidance of the two sets of guide bearings.
[0037] In summary, the conveyor chain adopts a double-bearing guide structure, and a first guide bearing 8 and a second guide bearing 10 are respectively arranged on the upper part and the side of the conveying guide seat 6. The two sets of guide structures are arranged to provide a stable guide support for the conveying chain 7 when the conveying chain 7 is turned, so that the conveyor can work more smoothly and turn more flexibly when conveying objects, and has advantages such as safety, reliability, low noise, and less wear. In addition, a protective structure is arranged on the connecting side of the conveying track 1 and the chain plate mechanism 2, and wear-resistant strips 4 and guide pads are respectively arranged on the top side and the inner side of the conveying track 1. Strip 5, through the support and protection of ultra-high molecular self-lubricating pad strips, the contact side of the conveyor track 1 and the bearing can be protected. Soft contact is adopted between the guide structures to reduce the working wear between the structures, reduce the working noise of the equipment and increase the service life of the equipment. Support guide wheels 18 are arranged on the lower parts of both sides of the conveyor chain plate 7. The support and guidance of the support guide wheels 18 can provide stable moving support for the moving conveyor chain plate 7, which can effectively reduce the contact friction between the conveyor chain plate 7 and the conveyor track 1, and improve the carrying capacity of the conveyor chain plate 7 while ensuring the stable movement of the conveyor chain plate 7.
