Technical Field
[0001] The utility model relates to the technical field of polyester conveying, in particular to a polyester conveying pipeline connecting device. Background Technique
[0002] Polyester is a polymer material obtained by the polycondensation reaction of polyols and polyacids. It is a kind of high-molecular compound containing ester bonds in the main chain, usually formed by the polycondensation of dibasic acids and diols through esterification reaction. There are many types of polyesters, among which polyethylene terephthalate (PET) is the most well-known and widely used polyester material.
[0003] Polyester usually shows fluidity in the molten state because molecules can move freely at high temperatures. This fluidity enables polyester to be effectively injection-molded into various shaped products, such as plastic bottles, fibers or films.
[0004] At present, the connection method between polyester conveying pipelines is to connect the pipelines through the use of hoop locks. However, many hoop locks are simply sleeved on the surfaces of the two pipelines and then fixed by tightening bolts. However, this fixing method is relatively superficial, and the connection between the pipelines is relatively unstable. Therefore, it does not meet the existing requirements, and for this reason, we propose a polyester conveying pipeline connecting device. Content of the Utility Model

[0023] An annular groove 210 for placing the hoop lock 112 is formed on the outer side of the first joint 110, there are three groups of circular grooves 130, and the three groups of circular grooves 130 are distributed in an annular array inside the circular groove 130.
[0024] A connection groove 160 is formed on the surface of the second joint 111, the docking seat 150 is movably installed inside the docking groove 140, and during the process that the end of the tightening bolt 131 extends into the docking groove 140, the end of the tightening bolt 131 pushes the docking seat 150, so that the docking seat 150 reaches inside the connection groove 160.
[0025] In this embodiment: during use, by inserting the first joint 110 and the second joint 111, and at the same time through the cooperation of the hoop lock 112 and the docking bolt 190, the connection between the first joint 110 and the second joint 111 is fixed. After the first joint 110 and the second joint 111 are fixed, the stability of the connection between the hoop lock 112 and the first joint 110 is strengthened by the tightening bolt 131 passing through the circular groove 130 and the docking groove 140. After the tightening bolt 131 reaches inside the docking groove 140, the front end of the tightening bolt 131 pushes the docking seat 150 to reach inside the connection groove 160, making the connection between the first joint 110 and the second joint 111 stable. At the same time, a sealing ring 121 is installed between the bottom side of the second joint 111 and the annular block 120 to strengthen the sealing performance of the connection between the first joint 110 and the second joint 111.
