The invention is convenient to operate, improves the refrigeration effect, makes the cooling uniform, can suck dust from the composite filaments, and collects dust and protects the environment.

[0004] For similar cooling devices, the cooling function inside the cooling device will reduce the temperature of the air, causing the water vapor in the air to condense into water, and the water vapor will condense into water droplets, thereby reducing the water vapor content in the air, resulting in a decrease in humidity. The decrease in humidity will cause changes in properties such as fiber drying and easy breakage, thereby affecting the quality of the product.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and a cooling device for producing polyester-polyamide composite filaments is proposed. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a problem that in the cooling device for producing polyester-polyamide composite filaments, the cooling function inside the cooling device will reduce the temperature of the air, causing the water vapor in the air to condense into water, and the water vapor will condense into water droplets, thereby reducing the water vapor content in the air, resulting in a decrease in humidity. The decrease in humidity will cause changes in properties such as fiber drying and easy breakage, thereby affecting the quality of the product.

Detailed Description of the Embodiment

[0020] The following further describes the embodiments of the present utility model in detail with reference to the drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0021] As Figures 1 to 4As shown in the figure, a cooling device for the production of polyester-polyamide composite filaments includes a housing 1, a spray head 8, cooling fan blades 9 and a humidity sensor 12. A wire inlet 2 is provided at the center of the left side of the housing 1. The wire inlet 2 is used to introduce the polyester-polyamide composite filaments into the cooling device, providing a passage for the composite filaments to enter the device. A wire outlet 3 is provided at the center of the right side of the housing 1. The wire outlet 3 is used to lead out the polyester-polyamide composite filaments processed by the cooling device. The positions of the wire inlet 2 and the wire outlet 3 are horizontally corresponding to each other, and the apertures of the wire inlet 2 and the wire outlet 3 are equal. The position of the wire inlet 2 corresponds to that of the wire outlet 3, facilitating the entry and exit of the composite filaments. On both sides of the inner cavity of the housing 1, wire guide rollers 13 are provided. The two ends of the two groups of wire guide rollers 13 are respectively abutted against the front and rear walls of the housing 1 through rotating shafts. The positions of the two groups of wire guide rollers 13 are horizontally corresponding to each other. The two groups of wire guide rollers 13 respectively guide and fix the composite filaments at the wire inlet 2 and the wire outlet 3, preventing the composite filaments from being entangled and misaligned. The positions of the two groups of wire guide rollers 13 correspond to each other, ensuring the smooth guidance of the composite filaments. A drain pipe 14 is provided at the lower end of the right side of the housing 1. The drain pipe 14 is used to discharge the waste water generated inside the cooling device, keeping the inside of the device clean and dry. A valve 15 is provided on the outer surface of the drain pipe 14. By adjusting the valve 15, the discharge of the waste water can be flexibly controlled;

[0022] A water storage tank 4 is provided at the center of the upper end surface of the housing 1. The water storage tank 4 is used to store cooling water, ensuring that there is sufficient water supply for the cooling system. A water outlet pipe 5 is provided at the lower end of the right side of the water storage tank 4. The water outlet pipe 5 is used to lead out the water source in the water storage tank 4 and deliver it to the water pump 6. A water pump 6 is provided on the right side of the water outlet pipe 5. One end of the water outlet pipe 5 far from the water storage tank 4 is connected to the suction end of the water pump 6. The water pump 6 pumps out the water source through the water outlet pipe 5. A water delivery pipe 7 is provided below the water pump 6. One end of the water delivery pipe 7 far from the spray head 8 is connected to the output end of the water pump 6. The water delivery pipe 7 guides the water source output by the water pump 6 into the spray head 8. The spray head 8 is provided on the lower end surface of the water delivery pipe 7. Three groups of spray heads 8 are provided. The three groups of spray heads 8 are arranged at equal intervals. The three groups of spray heads 8 are arranged at equal intervals, ensuring that the water source is evenly sprayed onto the entire surface of the polyester-polyamide composite filaments and the inner cavity of the housing 1. The humidity sensor 12 is provided on the side wall of the inner cavity of the housing 1. Through the feedback of the humidity sensor 12, the humidity inside the cooling device can be detected in real time;

[0023] At the center of the rear end face of the housing 1, a motor 10 is provided. The motor 10 provides kinetic energy output. The cooling fan blade 9 is arranged on the rear wall of the inner cavity of the housing 1. The cooling fan blade 9 rotates driven by the motor 10 to generate an air flow to help with heat dissipation and cooling. An air outlet 11 is opened on the front end face of the housing 1. The output end of the motor 10 is connected to the center of the cooling fan blade 9. The position of the cooling fan blade 9 and the air outlet 11 corresponds horizontally. Through the corresponding position with the cooling fan blade 9, the air from the cooling fan blade 9 is discharged from the air outlet 11 to realize the internal air circulation. The outer surface of the air outlet 11 is arranged in a louver structure. The louver-structured air outlet 11 is beneficial to the smooth discharge of air and prevents external dust from entering.

[0024] In summary, as Figures 1 to 4 shown, for the cooling device for producing polyester-cotton composite filaments, the polyester-cotton composite filaments enter the interior of the housing 1 through the inlet 2 on the left side of the housing 1, pass through two groups of wire rollers 13 and are discharged through the outlet 3. When the composite filaments pass through the interior of the housing 1, the cooling fan blade 9 is driven by the motor 10 to control the cooling fan blade 9 to rotate and generate an air flow, and then the composite filaments are air-cooled. The air flow is discharged through the louver structure of the air outlet 11 to realize the internal air circulation. When the humidity sensor 12 inside the housing 1 detects that the humidity inside the housing 1 is too low, it sends a signal to the control system. Subsequently, the control system controls the water pump 6 to start. The water pump 6 pumps out the water source in the water storage tank 4 through the water outlet pipe 5 and sends the water source into the three spray heads 8 through the water delivery pipe 7 by using the output end. The water flow passes through the specially designed spray holes of the spray heads 8. These spray holes can refine the water flow into very small water droplets. The refined water flow is sprayed out from the spray holes in the form of water droplets to form a mist-like water mist, so as to spray the interior of the device and the surface of the polyester-cotton composite filaments. Subsequently, the user adjusts the flow rate of the drain pipe 14 by controlling the opening and closing of the valve 15 to discharge.
