Description

Technical Field

[0001] The invention relates to the technical field of yarn production, in particular to a cooling layer forming unit for a cooling nylon yarn. Background Art

[0002] Yarns come in a variety of types, including covered yarn, stretch yarn, and nylon yarn. To enhance the yarn's cooling properties, a cooling nylon yarn with a cooling effect has been designed. Existing methods for creating cooling nylon yarns with this cooling effect involve adding a cooling agent to the nylon yarn's materials and then producing the yarn through a textile process. However, existing methods of creating cooling nylon yarns by adding a cooling agent to the nylon yarn's materials to form a mixed solution have the following drawbacks: The nylon yarn solution cannot be shared when producing nylon yarns with different cooling effects; switching between different types requires replacing all the materials, resulting in significant material waste. Furthermore, the cooling nylon yarns produced using existing processes have poor breathability and moisture absorption. Summary of the Invention

[0003] The present invention aims to provide a cooling nylon yarn cooling layer forming unit that can form a channel inside and store cooling agent powder to produce a cooling layer on a nylon yarn with a nylon yarn core, laying the foundation for the production of cooling nylon yarn with universal main body and good air permeability and moisture absorption.

[0004] The above technical problems are solved by the following technical solutions: a cooling layer forming unit for ice-cooled nylon yarn, characterized in that it includes a water bath and a drying box, one end of the water bath is provided with a traction wheel pair for pulling the nylon yarn into the water bath, and the other end is provided with an ice-cooled yarn output mechanism for pulling out the empty hollow nylon yarn body in the water bath; the drying box is used to dry the empty hollow nylon yarn body output from the water bath, so that the coolant solution adhered to the nylon yarn body is dried to form an ice-cooled layer; the traction wheel in the traction wheel pair is provided with a plurality of blades distributed along the circumference of the traction wheel, and the blades are used to pierce the nylon yarn body so that the ice-cooled layer The inner and outer spaces of the nylon yarn main body are connected; when in use, the traction wheel pair transports the nylon yarn into the water bath, and during the traction of the traction wheel, the nylon yarn main body is pierced by the blade to form air holes connecting the inner and outer spaces of the nylon yarn main body, and after the nylon yarn enters the water bath, the coolant powder is dissolved in the water in the water bath and washed out to form an empty hollow nylon yarn main body, and the coolant powder is dissolved in the water in the water bath to form a coolant solution, and the cooling yarn output mechanism outputs the empty hollow nylon yarn main body out of the water bath, and the coolant solution on the empty hollow nylon yarn main body is dried in a drying oven, and a cooling layer is formed after the cooling agent solution is dried.

[0005] Preferably, the nylon yarn body is provided with a plurality of nylon yarn body grooves extending in the direction of extension of the nylon yarn body, the nylon yarn body grooves being distributed along the circumference of the nylon yarn. The traction wheel is provided with an annular groove extending along the circumference of the traction wheel. The annular grooves of the two traction wheels are combined to form a nylon yarn passage hole for the nylon yarn body to pass through. The annular grooves are provided with an annular protrusion extending along the circumference of the annular groove. When the nylon yarn body passes through the nylon yarn passage hole, the annular protrusions on the two traction wheels are correspondingly inserted into the nylon yarn body grooves. When the traction wheel pair pulls the nylon yarn, traction is achieved only by friction between the annular protrusions and the sidewalls of the nylon yarn body grooves and the blades. This improves traction reliability and reduces the impact of traction on the yarn warp.

[0006] Preferably, the blade is arranged on the annular protrusion, so that the ventilation hole is located in the groove of the nylon yarn body, thereby preventing the ventilation hole of the produced cool nylon yarn from being blocked by the user when in use.

[0007] Preferably, the water bath is provided with a powder extrusion mechanism located above the liquid level in the water bath, the powder extrusion mechanism comprising a buffer bucket provided with a yarn outlet, a fixed clamping plate connected to the lower end of the yarn outlet, a movable clamping plate, and a clamping plate opening and closing cylinder for driving the movable clamping plate to open and close the fixed clamping plate, wherein the movable clamping plate and the fixed clamping plate are arranged horizontally. During use, the cooling agent powder is extruded from the air vents by the movable and fixed extrusion plates and falls into the water bath, thereby reducing the amount of cooling agent powder in the main body of the nylon yarn during the dissolution process and making the dissolution more rapid and sufficient.

[0008] Preferably, the water bath is provided with a dissolution acceleration mechanism, which includes a water pump and a water outlet sleeve. The water outlet sleeve has inner flanges at both ends, and the inner flanges are provided with a plurality of water outlet sleeve plugs distributed along the circumference of the water outlet sleeve. When the nylon yarn is inserted into the water outlet sleeve, the water outlet sleeve plugs are inserted into the grooves of the nylon yarn body in a one-to-one correspondence. The nylon yarn, the water outlet sleeve, and the inner flanges of the water outlet sleeve enclose a sealed water inlet cavity. The water outlet sleeve is provided with a water inlet hole connected to the sealed cavity, and the water inlet hole is connected to the outlet end of the water pump through an inlet pipe. When in use, the water pump draws water from the water bath and transports it to the sealed water inlet cavity. The water in the sealed water inlet cavity enters the nylon yarn body through the air vents on the part of the nylon yarn located inside the sealed water inlet cavity, and then flows out from the air vents on the part of the nylon yarn located outside the water outlet sleeve. The water is circulated between the inside and outside of the nylon yarn body, so that the cooling agent powder is fully and quickly dissolved, thereby improving the sand making efficiency.

[0009] Preferably, the nylon yarn thread passes through the outlet sleeve in a direction parallel to and coaxial with the outlet sleeve. This facilitates maintaining a seal between the outlet sleeve and the nylon yarn body, preventing bending and deformation that could result in a seal failure. This seal ensures water circulation between the interior and exterior of the nylon yarn body.

[0010] The present invention also includes an air pump, a vertical air-closing sleeve located above the liquid level of the water bath, and a shaping ring located above the air-closing sleeve. Both ends of the air-closing sleeve are provided with inner flanges of the air-closing sleeve, and the inner flanges of the air-closing sleeve are provided with a plurality of air-closing sleeve plugs distributed along the circumference of the air-closing sleeve. An air-closing cavity is provided in the air-closing sleeve, and the air-closing cavity is provided with an air inlet connected to the outlet end of the air pump; the inner surface of the air-closing sleeve is provided with a plurality of blowing nozzles connected to the air-closing cavity, and the blowing nozzles are distributed along the circumference of the air-closing sleeve, and the opening direction of the blowing nozzles is downward, and the air inlet is connected to the outlet end of the air pump through the air inlet pipe; an empty hollow nylon yarn body is passed through the air-closing sleeve When the shaping ring is in the upper position, the vacant hollow nylon yarn main body, the air cloth sleeve and the inner flange of the air cloth sleeve form a pressurized chamber, the air cloth sleeve plug is correspondingly inserted into the groove of the nylon yarn main body, and the blowing nozzle is correspondingly inserted into the groove of the nylon yarn main body; the inner circumferential surface of the shaping ring is provided with shaping teeth distributed along the circumference of the shaping ring, and the shape of the shaping teeth is the same as the cross-sectional shape of the groove of the nylon yarn main body; when the vacant hollow nylon yarn main body is inserted into the shaping ring, the shaping teeth are correspondingly inserted into the groove of the nylon yarn main body, and a gap of a set size is separated from the outer circumferential surface of the nylon yarn main body and the inner circumferential surface of the shaping ring. During use, the air pump inputs air into the cloth air cavity, and then blows air from the blowing nozzle. The air blown from the blowing nozzle flows downward through the air holes on the portion of the hollow nylon yarn body located in the boosting cavity, enters the hollow nylon yarn body, and then flows out through the air holes on the portion of the hollow nylon yarn body located below the cloth air sleeve, thereby blowing out the coolant solution in the hollow nylon yarn body. When the hollow nylon yarn body passes through the shaping ring, the shaping ring scrapes the outer surface of the hollow nylon yarn body to reduce the thickness of the coolant solution. This can prevent the internal cooling layer from being too thick, control the uniformity of the external cooling layer, and avoid localized spots caused by excessive cooling.

[0011] Preferably, the unused hollow nylon yarn body passes through the air-cloth sleeve in a direction parallel to and coaxial with the air-cloth sleeve; the unused hollow nylon yarn body passes through the shaping ring in a direction parallel to and coaxial with the shaping ring. This can improve the reliability of the air-blown nylon yarn body and the reliability of controlling the thickness of the cooling layer.

[0012] Preferably, the cooling yarn output mechanism is a yarn winding machine, which can be driven and synchronously wind the yarn.

[0013] The present invention has the following beneficial effects: it can be used to realize the production of cool nylon yarn covered with a cool layer, so that the nylon yarn body can be shared and the damage during the change of varieties can be reduced; the cool nylon yarn can be made into a fabric with improved air permeability and water absorption, thereby reducing the contact with the skin.

DETAILED DESCRIPTION

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figures 1 to 10 A cooling layer forming unit for ice-cooled nylon yarn includes a water bath 28 and a drying box 29. One end of the water bath is provided with a traction wheel pair 30 for pulling the nylon yarn in the cooling room into the water bath, and the other end is provided with an ice-cooled yarn output mechanism 31 for pulling out the empty hollow nylon yarn body in the water bath. The ice-cooled yarn output mechanism is a yarn winding machine.

[0027] The cooling nylon yarn 7 comprises a nylon yarn body 1 and a cooling agent powder filling line 61 filled within the nylon yarn body. The nylon yarn body is hollow and is provided with a plurality of nylon yarn body grooves 6 extending along the nylon yarn body. The nylon yarn body grooves are distributed along the circumference of the nylon yarn. The width of the nylon yarn body grooves gradually decreases from the opening end to the bottom end.

[0028] The cooling nylon yarn produced by the present invention includes a nylon yarn body 1. An outer cooling layer 2 is provided on the outer circumference of the nylon yarn body. The outer cooling layer covers the entire outer circumference of the nylon yarn body. The nylon yarn body is a hollow structure and is provided with a plurality of ventilation holes 3 that connect the inner and outer spaces of the nylon yarn body. An inner cooling layer 4 is provided on the inner circumference of the nylon yarn body, and a ventilation hole portion cooling layer 5 is provided within the ventilation hole. The inner cooling layer, the outer cooling layer, and the ventilation hole portion cooling layer are integrally formed together. The inner cooling layer covers the entire inner circumference of the nylon yarn body, and the ventilation hole portion cooling layer covers the entire hole wall of the ventilation hole. The nylon yarn body is provided with a plurality of nylon yarn body portion grooves 6 extending along the extension direction of the nylon yarn body. The nylon yarn body portion grooves are distributed along the circumference of the nylon yarn. The outer ends of the ventilation holes are located within the nylon yarn body portion grooves. The width of the groove of the nylon yarn main body portion gradually decreases from the opening end to the bottom end of the groove of the nylon yarn main body portion.

[0029] The drying oven is used to dry the empty hollow nylon yarn bodies discharged from the water bath, drying the coolant solution adhered to the nylon yarn bodies to form a cool layer. The axles 60 of the two traction wheels are parallel. The traction wheel 32 in the traction wheel pair is equipped with several blades 33 distributed along its circumference. These blades are used to pierce the nylon yarn body, connecting the interior and exterior spaces of the nylon yarn body. The traction wheels are provided with an annular groove 34 extending along their circumference. The annular grooves in the two traction wheels combine to form a nylon yarn passage 50 for the nylon yarn body 1 to pass through. An annular protrusion 35 extending along the circumference of the groove is provided within the annular groove. When the nylon yarn body passes through the nylon yarn passage, the annular protrusions on the two traction wheels correspond to each other and penetrate the groove of the nylon yarn body. When the traction wheel pair pulls the nylon yarn, traction is achieved solely through friction between the annular protrusions and the sidewalls of the nylon yarn body groove and the blades. The blades are mounted on the annular protrusions.

[0030] A powder extrusion mechanism is provided in the water bath, located above the liquid level 64 in the water bath. The powder extrusion mechanism is located on the discharge side of the traction wheel pair. The powder extrusion mechanism includes a buffer bucket 36 with a yarn outlet hole 67, a fixed splint 37 connected to the lower end of the yarn outlet hole, a movable splint 38, and a splint opening and closing cylinder 39 that drives the movable splint to open and close the fixed splint. The movable splint and the fixed splint are arranged in the horizontal direction. When the movable and fixed splints are closed to extrude the cooling agent powder in the nylon yarn body, the nylon yarn strands pulled out by the traction wheel pair are retained in the buffer bucket. When the movable and fixed splints are separated, the nylon yarn strands fall between the movable and fixed splints and are squeezed. The opening and closing speed and length of the movable and fixed splints and the speed of the traction wheel pair are controlled so that all the nylon yarn strands can be squeezed.

[0031] The water bath is equipped with a positioning wheel pair 40, a water outlet sleeve 41, and a reversing wheel 42. The nylon yarn, located between the positioning wheel pair and the reversing wheel, is positioned in a straight line 62 and threaded through the water outlet sleeve, parallel to and coaxial with the sleeve. The ring includes a water pump 43, which, together with the water outlet sleeve, forms the dissolution acceleration mechanism. Both ends of the water outlet sleeve are provided with an inner flange 44 of the water outlet sleeve, and the inner flange of the water outlet sleeve is provided with a number of water outlet sleeve plugs 45 distributed along the circumference of the water outlet sleeve; when the nylon yarn is passed through the water outlet sleeve, the water outlet sleeve plugs are passed through the groove of the nylon yarn main body in a one-to-one correspondence; the nylon yarn, the water outlet sleeve and the inner flange of the water outlet sleeve surround a sealed water inlet cavity, and the water outlet sleeve is provided with a water inlet hole 46 connected to the sealed water inlet cavity, and the water inlet hole is connected to the outlet end of the water pump through an inlet pipe 47; when in use, the water pump draws water from the water bath and transports it to the sealed water inlet cavity. The water in the sealed water inlet cavity enters the nylon yarn main body through the air vents on the part of the nylon yarn located in the sealed water inlet cavity, and then flows out from the air vents on the part of the nylon yarn located outside the water outlet sleeve, thereby accelerating the dissolution rate of the cooling agent in the nylon yarn, thereby realizing high-speed production. Thereby, the nylon yarn is formed into an empty hollow nylon yarn body 65, and the cooling agent powder is dissolved in the water bath to form cooling liquid.

[0032] Between the annular wheel and the drying box, an air distribution sleeve 48 and a shaping ring 49 are positioned above the sleeve. The sleeve is positioned vertically above the water bath. The hollow nylon yarn, located in a straight line 63 between the annular wheel and the drying box, is inserted into the sleeve and the shaping ring, parallel to and coaxial with the sleeve, and inserted into the shaping ring. The drainage system is aligned with and coaxial with the shaping ring. Both ends of the inner circumference of the air-cloth sleeve are provided with a plurality of air-cloth sleeve plugs 51 distributed along the circumference of the air-cloth sleeve, an air-cloth cavity 52 is provided in the air-cloth sleeve, and the air-cloth cavity is provided with an air inlet 54 connected to the outlet end of the air pump 53; the inner surface of the air-cloth sleeve is provided with a plurality of blowing nozzles 55 connected to the air-cloth cavity, the blowing nozzles are distributed along the circumference of the air-cloth sleeve, the opening direction of the blowing nozzles is downward, and the air inlet is connected to the outlet end of the air pump through the air inlet pipe 56; when the empty hollow nylon yarn body is passed through the air-cloth sleeve, the empty hollow nylon yarn body, the air-cloth sleeve and the inner flange of the air-cloth sleeve are surrounded by a pressurized The air is blown out from the blowing nozzle in a downward direction through the air vents on the part of the vacant hollow nylon yarn body located in the pressurized cavity, and then flows out from the air vents on the part of the vacant hollow nylon yarn body located below the outside of the air sleeve, thereby blowing out the coolant solution in the vacant hollow nylon yarn body to prevent excessive internal liquid accumulation. The inner circumference of the shaping ring is provided with shaping teeth 57 distributed along the circumference of the shaping ring, and the shape of the shaping teeth is the same as the cross-sectional shape of the groove of the nylon yarn main body; when the empty hollow nylon yarn main body is inserted into the shaping ring, the shaping teeth are inserted into the groove of the nylon yarn main body in a one-to-one correspondence, and a gap of a set size is separated between the outer circumference of the nylon yarn main body and the inner circumference of the shaping ring; when in use, when the empty hollow nylon yarn main body passes through the shaping ring, the shaping ring scrapes the outer surface of the empty hollow nylon yarn main body to a thickness greater than the required coolant solution.

[0033] The traction wheel pair outputs the nylon yarn from the cooling chamber into the water bath. During the traction process of the traction wheel, the nylon yarn main body is pierced by the blade to form air vents connecting the inner and outer spaces of the nylon yarn main body. After the nylon yarn enters the water bath, the coolant powder dissolves in the water in the water bath and is washed out to form an empty hollow nylon yarn main body. The coolant powder dissolves in the water in the water bath to form a coolant solution. The coolant yarn output mechanism outputs the empty hollow nylon yarn main body into the water bath. After the empty hollow nylon yarn main body is output from the water bath, the coolant solution on the empty hollow nylon yarn main body is dried by the drying oven. After the coolant solution is dried, a cool layer is formed (that is, the coolant solution inside the nylon yarn main body dries to form an inner cool layer, the coolant in the air vents is easily dried to form a cool layer at the air vent part, and the coolant solution outside the nylon yarn main body dries to form an outer cool layer), so that the empty hollow nylon yarn main body 65 becomes a cool nylon yarn 66.
