Description

Technical Field

[0001] The utility model relates to the technical field of spinneret radiators, in particular to a spinneret radiator used for producing polyester low-stretch yarn. Background Art

[0002] In the production and processing of polyester low-elastic yarn, spinnerets are often required. Spinnerets are a key component used in the spinning process. They are usually used in the spinning process in 3D printing, inkjet printing, textiles, fiber manufacturing and other fields. The function of the spinning nozzle is to heat the material to a certain temperature and spray it out through tiny nozzles to form continuous filaments. The nozzle controls the flow and direction of the material so that it moves along a predetermined path during weaving or printing, thereby creating the required textile or printing structure. The spinneret will generate a higher temperature when used continuously, so a radiator is needed to dissipate heat from the spinneret.

[0003] Existing polyester low-elastic yarn spinneret radiators are mostly fixed on the nozzle surface during use, so that multiple heat dissipation plates inside the radiator fit the nozzle surface, so that the multiple heat dissipation plates absorb the heat generated by the nozzle and volatilize it, thereby achieving auxiliary heat dissipation treatment for the nozzle.

[0004] However, since the temperature generated by the nozzle is relatively high when used for a long time and the heat absorption of the heat sink is limited, the heat dissipation speed of the radiator may be relatively slow, affecting the heat dissipation effect of the nozzle. Utility Model Content

[0007] The effects achieved by the above components are as follows: first, the radiator body is fixedly mounted on the nozzle surface, so that the multiple heat dissipation plates inside the radiator body fit the nozzle surface, so that the multiple heat dissipation plates absorb the heat generated by the nozzle and volatilize it, and at the same time cooperate with the auxiliary device to increase the heat flow rate inside the radiator body and improve the heat dissipation speed, thereby achieving auxiliary heat dissipation treatment of the nozzle.

[0008] Preferably, the auxiliary device includes a support frame and an annular cylinder, the support frame is fixedly connected to the radiator body, one side of the support frame is fixedly connected to a motor, the output end of the motor is fixedly connected to a gear, one side of the support frame is provided with a rectangular hole, the surface of the radiator body is provided with a plurality of circular through holes, the annular cylinder is sleeved on the surface of the radiator body, the annular cylinder is located inside the support frame, one side of the annular cylinder is fixedly connected to a fan, one side of the annular cylinder is fixedly connected to a circular hole block, one side of the circular hole block is fixedly connected to a gear rod, the gear rod is provided inside the rectangular hole, and the gear rod is meshed with the gear.

[0009] The effect achieved by the above components is as follows: by setting an auxiliary device, first start the motor, so that the motor drives the gear to rotate, so that the gear drives the gear rod to move left and right along the inside of the rectangular hole, so that the gear rod drives the circular hole block to move left and right, so that the circular hole block drives the annular cylinder to move left and right along the surface of the radiator body. At this time, start the fan, so that the fan injects air into the inside of the annular cylinder, so that the air inside the annular cylinder is blown out through multiple circular holes during the reciprocating movement of the annular cylinder, and at the same time enters between the multiple heat dissipation plates inside the radiator body, and takes the heat between the multiple heat dissipation plates away from the inside of the radiator body. At the same time, auxiliary heat dissipation is performed on the surfaces of the multiple heat dissipation plates, accelerating the heat absorption and volatilization rate of the nozzle surface, reducing the situation where the heat dissipation speed of the radiator is relatively slow due to the limited heat absorbed by the heat dissipation plate when the temperature of the nozzle itself is high, and improving the heat dissipation effect of the nozzle.

[0010] Preferably, a guide rod is fixedly connected to the inner wall of the support frame, and the surface of the guide rod is slidably connected to the inner wall of the circular hole block.

[0011] The effect achieved by the above components is: by setting the guide rod, the guide rod can be located inside the circular hole block to assist in limiting the gear rod and the annular cylinder, thereby reducing the shaking or position displacement of the annular cylinder and the gear rod during use.

[0012] Preferably, a sealing strip is fixedly connected to the inner side of the annular cylinder, and the surface of the sealing strip is in contact with the surface of the radiator body.

At this time, the bolt is rotated by a tool so that the bolt is rotated into the circular hole plate and the internal position of the threaded groove to fix the position of the circular hole plate and the radiator body, thereby completing the assembly between the radiator body and the nozzle.
