Description

Technical Field

[0001] The utility model relates to the technical field of filament warping machines, in particular to a cylinder rotary joint of a warping machine. Background Technique

[0002] At present, the drying part of a filament warping machine consists of two parts. One part is called the oven, usually with two to three sections; the other part is called the cylinder. The main drying part of the cylinder is five drying cylinders, which belong to pressure vessels. By injecting steam into the drying cylinders, the surface temperature of the drying cylinders is increased, so as to achieve the effect of secondary drying and shaping of the silk wound on the surface of the drying cylinders. During use, the steam inside the drying cylinders will gradually form condensate over time, and the formed condensate needs to be discharged from the drying cylinders. The injection of steam and the discharge of condensate are both completed through a rotary joint and a matching siphon tube. The rotary joint has a steam inlet and a drain outlet, and the drain outlet is connected to the siphon tube.

[0003] In the prior art, due to the single fulcrum of the siphon tube inside the rotary joint, the siphon tube sags and rubs against the inner wall of the drying cylinder, resulting in a relatively large abnormal noise during the operation of the equipment. When worn to a certain extent, the thread of the siphon tube will break, and the siphon tube will fall into the drying cylinder, unable to discharge the condensate inside the drying cylinder, and the temperature on the surface of the drying cylinder will decrease, resulting in the cylinder not being able to achieve a good drying and shaping effect on the silk, and not meeting the actual use requirements. Content of the Utility Model

[0004] The purpose of the utility model is to provide a cylinder rotary joint of a warping machine to solve the problems raised in the above background technique.

[0006] The rotary joint main body includes a rotary joint connecting head and a support assembly. The support assembly is arranged at one end of the rotary joint connecting head, and the arranged support assembly is embedded in the rotary joint connecting head. The arranged support assembly is used to support and protect the siphon tube in the rotary joint main body;

[0007] One end of the siphon tube is fixedly connected with a thread, and the thread arranged at the end of the siphon tube passes through the support assembly and is connected with the thread inside the other end of the rotary joint connecting head.

[0008] Preferably, fixed holes are equidistantly and symmetrically fixedly arranged at one end of the rotary joint connecting head, and the fixed holes are connected with the rotary joint main body through the arranged fixing pins. A limiting groove is fixedly arranged at the central position of one end of the rotary joint connecting head, and the arranged limiting groove is correspondingly connected with the support assembly.

[0009] Preferably, the support assembly includes a limit block, and the limit block is arranged in the limit groove on the end face of the rotary joint connector, and a connection hole is fixedly arranged at the center position of one end of the limit block, and the aperture of the arranged connection hole is equal to the diameter of the siphon tube.

[0010] Preferably, a plurality of limit bumps are fixedly arranged at equal intervals at one end of the limit block, and the arranged limit bumps are connected to the connection hole.

[0011] Preferably, a plurality of limit grooves are fixedly arranged at equal intervals at one end of the limit block, and the arranged limit grooves are connected to the connection hole.
