Most existing polyester filament setting devices mostly need to obtain the set polyester filaments through two large heating and cooling steps during the setting process of polyester filaments, and a relatively long time is occupied by the heat dissipation of the polyester filaments in the above two steps.

A heat dissipation member 2 is provided in the cooling chamber 121. The heat dissipation member 2 includes a heat dissipation frame 31 concentrically arranged with the cooling chamber 121. A heat dissipation chamber 311 for the polyester filaments to pass through and dissipate heat is opened in the heat dissipation frame 31. A plurality of heat dissipation blades 32 are arranged at intervals in the circumferential direction of the heat dissipation frame 31. An exchange channel 321 for cold and hot air exchange is formed between two adjacent heat dissipation blades 32. A driving member 3 for driving the circumferential rotation of the heat dissipation frame 31 is provided outside the heat dissipation frame 31. Through the arrangement of the heating chamber 12 and the cooling chambers 121 in the heating cylinder 1, the setting process of the polyester filaments can be carried out orderly and stably. And through the arrangement of the partition plate 22, the purpose of temperature differentiation between the two partitions can be achieved. And through the through hole 21, the polyester filaments can enter the heat dissipation chamber 311 orderly. And by rotating the heat dissipation frame 31 to drive the heat dissipation blades 32 to rotate, the purpose of accelerating the heat dissipation efficiency of the polyester filaments is achieved, and the overall setting efficiency of the polyester filaments can be greatly improved.

[0023] It should be noted that, in order to ensure that the heating and cooling processes of the above-mentioned heating cylinder 1 are more stable and will not cause damage to the heating cylinder 1, in this embodiment, a protective layer 11 for protecting the heating cylinder 1 is provided on the inner wall of the heating cylinder 1, and a plurality of heating elements 13 for uniformly heating the inside of the heating chamber 12 are distributed on one inner wall of the protective layer 11 in the heating chamber 12; the purpose of protecting the heating cylinder 1 can be achieved through the setting of the protective layer 11, and the purpose of orderly and uniformly heating the polyester filaments entering the heating chamber 12 can be achieved through the setting of the plurality of heating elements 13.

[0024] Furthermore, the above-mentioned heating elements 13 are uniformly distributed along the inner wall of the heating chamber 12, and in this embodiment, the above-mentioned heating cylinder 1 is cylindrical, and the internal heating chamber 12 and cooling chamber 121 are both cylindrical.

[0025] It should be noted that, in order to enable the polyester filaments to enter the heating cylinder 1 orderly for transmission, in this embodiment, a plurality of first transmission wheels 14 and second transmission wheels 15 for tensioning and transmitting the polyester filaments are provided between the side walls of the heating chamber 12, and the second transmission wheel 15 is located between the first transmission wheel 14 and the through hole 21 for buffering the transmission of the polyester filaments; the purpose of enabling the polyester filaments to enter the heating chamber 12 orderly can be achieved through the setting of the first transmission wheels 14 and second transmission wheels 15, and the polyester filaments can orderly extend into the through hole 21 and enter the cooling chamber 121 along the first transmission wheels 14 and second transmission wheels 15.

[0026] Specifically, a feed port 111 and a discharge port 112 are respectively opened on both sides of the heating cylinder 1, the feed port 111 is on one side of the heating chamber 12, the discharge port 112 is on one side of the cooling chamber 121, and protective pads 113 for protecting the polyester filaments are provided in the feed port 111 and the discharge port 112; the purpose of enabling the polyester filaments to extend in and out orderly can be achieved through the setting of the feed port 111 and the discharge port 112, and the setting of the protective pads 113 can also prevent the side wall of the heating cylinder 1 from damaging the polyester filaments.

When the heat dissipation frame 31 rotates, the heat dissipation blades 32 are driven to rotate, so that the heat in the polyester filaments in the heat dissipation chamber 311 flows outwards along the exchange channel 321.
