It has the advantages of few failures, simple operation, and low investment cost. However, the above melt-spinning cooling device has some disadvantages, such as: the outside air enters the cooling channel through the air inlet pipe and is then discharged through the air outlet pipe. Impurities in the air will adhere to the filaments, thereby affecting the quality of the filaments, which needs to be improved. Utility Model Content

[0005] The purpose of the present application is to provide a melt direct spinning cooling device in order to reduce the adhesion of impurities on the filaments.

[0007] By adopting the above technical solution, when the outside air enters the cooling pipeline through the air inlet pipeline, it needs to pass through the filter screen first. The filter screen can effectively separate the impurities in the air, improve the purity of the air, and thus reduce the impurities from entering the cooling pipeline and adhering to the filaments.

[0008] Optionally, the air inlet pipeline is detachably connected with a mounting plate, the filter screen is connected to the mounting plate, the air inlet pipeline is provided with a mounting channel for the mounting plate to pass through, the mounting channel is communicated with the air inlet pipeline, and the mounting plate is connected with a fixing component for mounting the mounting plate on the air inlet pipeline.

[0009] By adopting the above technical solution, after a large amount of impurities adhere to the filter screen, the fixing component loosens the mounting plate, and the mounting plate and the filter screen can be taken out of the air inlet pipeline together, which is convenient for cleaning the filter screen.

[0010] Optionally, the air inlet pipeline is provided with a support groove for the mounting plate to be snapped into, and both the air inlet pipeline and the mounting channel are communicated with the support groove.

[0011] By adopting the above technical solution, the mounting plate is snapped into the support groove, and the inner wall of the mounting plate fits with the inner wall of the support groove. The inner wall of the support groove plays a supporting role for the mounting plate, thereby improving the stability of the mounting plate placed on the air inlet pipeline and facilitating the fixing component to mount the mounting plate on the air inlet pipeline.

[0012] Optionally, the inner wall of the mounting channel is connected with a gasket for abutting against the mounting plate.

[0013] By adopting the above technical solution, the gasket is used to seal the gap between the inner wall of the mounting channel and the mounting plate, improving the sealing performance.

[0014] Optionally, the fixing component includes two fixing rods slidably connected to the mounting plate and an active structure for driving the two fixing rods to slide in the direction of approaching or separating from each other. The active structure is connected to the mounting plate, and the air inlet pipeline is provided with a fixing groove for the corresponding fixing rod to be snapped into.

[0015] By adopting the above technical solution, the mounting plate is snapped into the support groove so that the fixing rods correspond to the fixing grooves. The active structure drives the two fixing rods to slide in the direction of separating from each other, so that the fixing rods are snapped into the fixing grooves. The inner wall of the fixing groove plays a role in restricting the movement of the fixing rods, that is, restricting the mounting plate from moving out of the support groove, thereby improving the stability of the mounting plate mounted on the air inlet pipeline.

[0016] Optionally, the active structure includes an active plate slidably connected to the mounting plate, the two fixed rods are connected by an elastic member, each of the fixed rods is connected to a passive rod, the passive rod is provided with a first guide surface for movably abutting against the active plate, and the active plate is provided with a clearance groove for the passive rod to be engaged.

[0017] By adopting the above technical solution, when installing the mounting plate, the active plate is moved in the direction close to the passive rod, the active plate movably contacts with the first guide surface and drives the two passive rods to slide in the direction close to each other, that is, the two fixed rods slide in the direction close to each other, the elastic member is elastically deformed and compressed under pressure, so that the fixed rod retracts into the mounting plate, which is convenient for the mounting plate to be inserted into the support groove. When the fixed rod corresponds to the fixed groove, the active plate is released, the elastic member is elastically reset, and the elastic member forces the two fixed rods to slide in the direction away from each other, that is, the two passive rods slide in the direction away from each other, and the fixed rod is inserted into the fixed groove, thereby improving the stability of the mounting plate installed on the air inlet duct; the passive rod movably contacts with the active plate, and the passive rod drives the active plate to reset, which is convenient for the active plate to be used again.

[0018] Optionally, the mounting plate is connected to a limiting rod, and the active plate is provided with a waist-shaped hole for slidingly cooperating with the limiting rod.

[0019] By adopting the above technical solution, when the active plate slides, the sliding cooperation between the limit rod and the waist-shaped hole plays a guiding and limiting role in the sliding of the active plate, thereby improving the sliding stability of the active plate and preventing the active plate from detaching from the mounting plate during the sliding process.

[0020] Optionally, the fixing rod is provided with a second guide surface for movably abutting against the air inlet duct.

[0021] By adopting the above technical solution, when the mounting plate is inserted into the support groove, the air inlet duct is movably abutted against the second guide surface, and the air inlet duct drives the two fixing rods to retract into the mounting plate, and the elastic member is elastically deformed and compressed under pressure, thereby eliminating the step of driving the two fixing rods to move by the active plate, thereby improving the installation efficiency of the mounting plate. When the fixing rod corresponds to the fixing groove, the elastic member is elastically reset, so that the fixing rod is inserted into the fixing groove, and the mounting plate is installed.

[0022] Optionally, the cooling component includes a water inlet pipe and a water outlet pipe connected to the cooling pipe, the water inlet pipe and the water outlet pipe are located between the air inlet pipe and the air outlet pipe, and the water inlet pipe is connected to the water outlet pipe through a condensation pipe.

[0023] By adopting the above technical solution, condensed water enters the condensation pipe through the water inlet pipe and flows out from the water outlet pipe. The condensed water takes away the heat on the filaments during the flow, thereby reducing the temperature of the filaments.

[0024] Optionally, the condensation pipeline is arranged in a spiral shape.

[0025] By adopting the above technical solution, the spiral condensation pipeline increases the flow path of the condensed water in the cooling pipeline, that is, increases the contact area between the hot air and the condensation pipeline, and improves the cooling effect of the filament.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. The filter screen can effectively separate impurities in the air, improve the purity of the air, and thus reduce the entry of impurities into the cooling pipeline and adhesion to the filament.

[0028] 2. The spiral condensation pipeline increases the flow path of the condensed water in the cooling pipeline, that is, increases the contact area between the hot air and the condensation pipeline, and improves the cooling effect of the filament. BRIEF DESCRIPTION OF THE DRAWINGS
