Description

Technical Field

[0001] The present invention belongs to the technical field of down jacket production equipment, and particularly relates to a production equipment for leak-proof and breathable goose down fabric. Background Art

[0002] Natural down has significant heat preservation characteristics compared with artificial materials. Natural down is taken from the underfur of the abdomen and axilla of geese or ducks. Compared with duck down, goose down has larger down clusters, higher fluffiness, and better comfort. In addition, the breeding cost of geese is relatively high, so goose down fabric is relatively precious. Since down jackets need to ensure breathability and leak-proof ability at the same time, high-end goose down jackets mostly use high-density poplin as the inner lining cloth, which can prevent the down from leaking out of the down jacket and ensure its breathable characteristics.

[0003] The formation of the down leakage phenomenon in down jackets is mainly related to the fabric tightness index, the quality of the down, and the sewing quality. During the sewing process of down jackets, down needs to be filled between the two layers of inner lining cloth of the down jacket fabric. During the production of down jackets, the inner lining cloth is first sewn partially, and then the down is filled from the unsewn part. In order to avoid the accumulation of down in local positions inside the down jacket, the quilting process needs to be used to process the down jacket fabric, and the down is separated and pressed by quilting. However, during the sewing process of quilting, the sewing machine needle tip may bring out the down from the needle holes on the inner lining cloth, and at this time, the needle holes are also likely to be enlarged, which has a negative impact on the leak-proof ability of the down jacket. Summary of the Invention

[0004] The purpose of the present invention is to provide a production equipment for leak-proof and breathable goose down fabric to solve the above problems and prevent the quilting process from having an adverse impact on the leak-proof ability of the down jacket fabric.

[0005] The present invention achieves the above purpose through the following technical solutions:

[0006] A production device for leak-proof and breathable goose down fabric, including a down filling mechanism and a gas supply system for pneumatically conveying to the down filling mechanism. It also includes a kneading mechanism for receiving and compressing the down conveyed by the down filling mechanism and an introducing mechanism for transmitting the compressed down between two layers of lining fabrics of the goose down fabric. When sewing the fabric of a down jacket, make two layers of lining fabrics into multiple long tubular fabrics that are sewn together at one end and open at the other end. Sleeve the long tubular fabric outside the introducing mechanism. Through the cooperation of the down filling mechanism and the gas supply system, fill the down into the kneading mechanism. The kneading mechanism compresses the down and transmits the compressed down to the inside of the long tubular fabric through the introducing mechanism. Quilt the fabric in the direction parallel to the opening of the long tubular fabric, so as to seal the compressed down in the long tubular fabric, and fill a row of compressed down between the two layers of lining fabrics. During the quilting process, the compressed down can move away from the quilting points. Repeat the above operations to fill multiple rows of down between the two layers of lining fabrics, complete the sewing and down filling of the lining fabric of the down jacket. After sewing the opening of the fabric, perform low-temperature drying on the down in the lining fabric, and pat the lining fabric during the drying process to make the compressed down in the two layers of lining fabrics return to the natural fluffy state;

[0007] The kneading mechanism includes a transfer component for transferring the down to the inside of the introducing mechanism, a cylinder located above the transfer component, a pressing component arranged inside the cylinder, a shaking component arranged on one side of the cylinder, and a humidifying component communicated with the cylinder. Keep the inside of the cylinder in a humid environment through the humidifying component. The cylinder has openings at both the upper and lower ends, and the bottom end of the cylinder is in contact with the transfer component. During the process of compressing the down, fill the down into the inside of the cylinder through the down filling mechanism. The pressing component cooperates with the shaking component to first press the down inside the cylinder into a flat shape, and then knead it into a strip shape, so that the down can move away from the quilting points during the quilting process.

[0008] As a further optimized scheme of the present invention, the pressing component includes a first cylinder fixedly arranged at the top of the cylinder and a pressing plate fixedly arranged at the output end of the first cylinder. The first cylinder compresses the down in the cylinder into a flat shape through the pressing plate; the shaking component includes a second cylinder located on one side of the cylinder and a fixed frame fixedly arranged at the output end of the second cylinder. The fixed frame is fixedly installed outside the cylinder. The second cylinder makes the cylinder reciprocate on the transfer component through the fixed frame to process the down into a strip shape.

[0009] As a further optimized scheme of the present invention, two first arc surfaces are oppositely arranged on both sides of the lower end of the pressing plate, and two second arc surfaces are oppositely arranged at the bottom of the inner side wall of the cylinder. The arrangement directions of the second arc surface and the first arc surface are both perpendicular to the arrangement direction of the second cylinder. Extrude the down through the first arc surface and the second arc surface, so that during the reciprocating sliding process of the cylinder, compress the down into a cylindrical shape to reduce the frictional resistance when transmitting the compressed down.

[0010] As a further optimized solution of the present invention, the transfer component includes a support table, a third cylinder rotatably arranged at the top of the support table, a transfer plate rotatably arranged at the output end of the third cylinder, pressure sensors fixedly arranged on the top of the transfer plate and corresponding to the cylinders one by one, and material loading grooves fixedly arranged at the tops of the pressure sensors. A support frame hinged to the transfer plate is fixedly arranged at the top of the support table. The position where the transfer plate is hinged to the support frame is the end of the transfer plate close to the fluff filling mechanism. During the process of fluff filling from the fluff filling mechanism to the kneading mechanism and the kneading mechanism compressing the down, the transfer plate and the material loading groove of the transfer component remain in a horizontal state. The weight of the down in the cylinder is detected by the pressure sensor. When the weight of the down reaches the set value, the fluff filling mechanism stops filling. When the transfer component transfers the compressed down, the third cylinder drives the transfer plate to swing downward, so that the compressed down slides into the guiding mechanism.

[0011] As a further optimized solution of the present invention, the shaking component further includes a mounting frame fixedly arranged at the top of the support table, slide rails oppositely arranged at the tops of both sides of the mounting frame, and two groups of rollers rotatably arranged at both ends of the fixed frame. The two groups of rollers are respectively arranged inside the two slide rails. The slide rails fixed to the top of the mounting frame support the cylinder through the rollers and the fixed frame.

[0012] As a further optimized solution of the present invention, the humidifying component includes a water pump, a water tank connected to the water pump and a third shunt pipe, third two-way valves uniformly arranged on the outer side of the third shunt pipe, diffusion nozzles communicated with the third two-way valves, and humidity sensors for detecting the humidity inside the cylinder. The diffusion nozzles correspond to the cylinders one by one and are arranged through the side walls of the cylinders. The humidity inside the cylinder is detected by the humidity sensors. When the humidity inside the cylinder is lower than the set value, the corresponding third two-way valve is opened. The water pump pumps the water in the water tank into the diffusion nozzles through the third shunt pipe and the third two-way valves, and the inside of the cylinder is humidified through the diffusion nozzles.

[0013] As a further optimized solution of the present invention, the fluff filling mechanism includes storage hoppers corresponding to the cylinders one by one and discharge valves communicated with the storage hoppers. The upper end of the discharge valve is communicated with the air supply system. A guide pipe is fixedly arranged at the lower end of the discharge valve. A through hole is opened on one side of the cylinder close to the discharge valve. The discharge valve is connected to the through hole through the guide pipe. The fluff filling mechanism discharges the down in the storage hopper into the through hole of the cylinder through the discharge valve and the guide pipe. When the pressure sensor detects that the weight of the down reaches the set value, the motor of the discharge valve is turned off.

[0014] As a further optimization scheme of the present invention, the air supply system includes a fan, a three-way valve connected to the fan, a first diversion pipe connected to the three-way valve, and a first two-way valve evenly arranged on the outside of the first diversion pipe. The first two-way valve corresponds to the discharge valve one by one. During the filling process, the first two-way valve is opened, and the upper and lower ends of the three-way valve are connected. The air supply system pneumatically conveys the down at the discharge valve through the fan. When the motor of the discharge valve is turned off, the fan and the first two-way valve are also closed at the same time.

[0015] As a further optimization solution of the present invention, the introduction mechanism includes a feed pipe corresponding one-to-one to the loading trough and a feeding pipe fixedly arranged at the bottom end of the feed pipe.

[0016] As a further optimization scheme of the present invention, a second diversion pipe is provided above the side of the discharge pipe close to the loading trough, and the lower end of the second diversion pipe is connected to a second two-way valve corresponding to the discharge pipe one by one, and a fan-shaped nozzle is fixedly provided at the lower end of the second two-way valve. An air inlet corresponding to the fan-shaped nozzle is provided on the discharge pipe, and the second diversion pipe is connected to the three-way valve. The air supply system uses a fan in conjunction with the fan-shaped nozzle to spray the compressed down in the discharge pipe to ensure that the compressed down can smoothly pass through the feeding pipe into the bile cloth.

[0017] The beneficial effects of the present invention are:

[0018] 1) When sewing fabric, the present invention manufactures two layers of lining cloth into a plurality of long cylindrical fabrics sewn together with one end open. Down is filled into the kneading mechanism through a filling mechanism in cooperation with an air supply system. The kneading mechanism compresses the down and transfers the compressed down into the fabric through an introduction mechanism. When quilting in a direction parallel to the fabric opening, contact between the needle tip and the down is avoided, thereby preventing the needle hole on the lining cloth from enlarging during the quilting process, thereby improving the down leakage prevention performance of the down jacket.

[0019] 2) The present invention squeezes the down through the first curved surface on the pressing plate and the second curved surface on the cylinder, so that the cylinder compresses the down into a cylindrical shape during the reciprocating sliding process, reducing the friction resistance when transmitting the compressed down. The air supply system uses a fan in conjunction with a fan-shaped nozzle to blow the compressed down in the feed pipe, ensuring that the compressed down can smoothly pass through the feeding pipe into the bladder cloth, thereby improving equipment reliability.

[0029] The following further describes the present application in detail with reference to the drawings. It is necessary to point out here that the following specific implementation manners are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0030] Such as Figure 1As shown in the figure, a production device for leak-proof and breathable goose down fabric includes a down filling mechanism 1 and a gas supply system 2 for pneumatically conveying to the down filling mechanism 1. It also includes a kneading mechanism 3 for receiving and compressing the down conveyed by the down filling mechanism 1 and a guiding mechanism 4 for transmitting the compressed down between two layers of lining fabrics of the goose down fabric. The lining fabric is preferably high-density poplin, which can endow the lining fabric of the down jacket with the characteristics of preventing down leakage and breathability. The down is preferably goose down, which can ensure the fluffiness and comfort of the down jacket fabric. When sewing the down jacket fabric, first sew the edges of the two layers of lining fabrics on the sewing table and leave an unsewn opening to form a bag-shaped fabric. Quilt the bag-shaped fabric in a direction perpendicular to the opening of the bag-shaped fabric. After quilting multiple times, a plurality of open-ended long tubular fabrics connected together are formed. The long tubular fabric is sleeved on the outside of the guiding mechanism 4. The down filling mechanism 1 cooperates with the gas supply system 2 to fill the kneading mechanism 3 with down. The kneading mechanism 3 compresses the down and transmits the compressed down to the inside of the long tubular fabric through the guiding mechanism 4. Move the long tubular fabric away from the guiding mechanism 4, and then quilt in a direction parallel to the opening of the long tubular fabric, so as to seal the compressed down in the long tubular fabric, and fill a row of compressed down between the two layers of lining fabrics. During the quilting process, the compressed down can move away from the quilting points. Repeat the above operations to fill multiple rows of down between the two layers of lining fabrics, completing the sewing and down filling of the lining fabric of the down jacket. After sewing the fabric opening, perform low-temperature drying on the down in the lining fabric. The drying temperature is preferably 35°C. During the drying process, pat the lining fabric to make the compressed down in the two layers of lining fabrics return to the natural fluffy state.

[0031] As Figure 2 shown in the figure, the kneading mechanism 3 includes a transfer component for transferring the down to the inside of the guiding mechanism 4, a cylinder body 301 located above the transfer component, a pressing component arranged inside the cylinder body 301, a shaking component arranged on one side of the cylinder body 301, and a humidifying component communicated with the cylinder body 301. The number of cylinder bodies 301 is set to be multiple according to actual needs. The humidifying component keeps the inside of the cylinder body 301 in a humid environment. The cylinder body 301 has openings at both the upper and lower ends. The bottom end of the cylinder body 301 is in contact with the transfer component. During the process of compressing the down, the down filling mechanism 1 fills the down into the inside of the cylinder body 301. The pressing component cooperates with the shaking component to first press the down inside the cylinder body 301 into a flat shape, and then knead it into a strip shape, so that the down can move away from the quilting points during the quilting process. Specifically, the down filling mechanism 1 fills the down into the inside of the cylinder body 301. The pressing component presses the down into a flat shape. The shaking component drives the cylinder body 301 to reciprocate on the transfer component, kneading the down inside the cylinder body 301 into strip-shaped compressed down. Then the transfer component transmits the compressed down to the inside of the guiding mechanism 4. When quilting in a direction parallel to the fabric opening, the down agglomerates inside the long tubular fabric, avoiding the contact between the needle tip and the down, and preventing the needle holes on the lining fabric from expanding during the quilting process.

[0032] Further, as Figure 2-4 shown, the pressing component includes a first cylinder 302 fixedly arranged at the top of the cylinder body 301 and a pressing plate 303 fixedly arranged at the output end of the first cylinder 302. The first cylinder 302 compresses the down in the cylinder body 301 through the pressing plate 303, pressing the down into a flat shape; the shaking component includes a second cylinder 304 located on one side of the cylinder body 301 and a fixing frame 305 fixedly arranged at the output end of the second cylinder 304. The fixing frame 305 is fixedly installed on the outer side of the cylinder body 301. The fixing frames 305 are connected end to end and are fixedly arranged around the outer sides of multiple cylinder bodies 301. The second cylinder 304 makes the cylinder body 301 reciprocate and slide on the transfer component through the fixing frame 305, kneading the down into a strip shape.

[0033] Further, as Figure 3-5 shown, two first arc surfaces 306 are oppositely arranged on both sides of the lower end of the pressing plate 303, and two second arc surfaces 307 are oppositely arranged at the bottom of the inner side wall of the cylinder body 301. The arrangement directions of the second arc surface 307 and the first arc surface 306 are both perpendicular to the arrangement direction of the second cylinder 304. By arranging the first arc surface 306 at the lower end of the pressing plate 303 and the second arc surface 307 at the bottom of the cylinder body 301, when the cylinder body 301 reciprocates and slides, the down is compressed into a cylindrical shape, reducing the frictional resistance when transporting and compressing the down.

[0034] Further, as Figure 2-4 shown, the transfer component includes a support platform 308, a third cylinder 309 rotatably arranged at the top end of the support platform 308, a transfer plate 310 rotatably arranged at the output end of the third cylinder 309, a pressure sensor 311 fixedly arranged at the top of the transfer plate 310 and corresponding to the cylinder body 301 one by one, and a loading groove 312 fixedly arranged at the top end of the pressure sensor 311. A support frame hinged to the transfer plate 310 is fixedly arranged at the top end of the support platform 308. The position where the transfer plate 310 is hinged to the support frame is the end of the transfer plate 310 close to the filling mechanism 1. Guide rods are fixedly arranged at the four corners of the bottom end of the loading groove 312. A limiting tube is sleeved on the outer side of the guide rod, and the limiting tube is fixedly connected to the top end of the transfer plate 310. The limiting tube limits the loading groove 312 through the guide rod, so that the loading groove 312 is kept parallel to the transfer plate 310. During the process of the filling mechanism 1 filling the kneading mechanism 3 with down and the kneading mechanism 3 compressing the down, the transfer plate 310 and the loading groove 312 of the transfer component remain in a horizontal state, and the inner bottom end of the loading groove 312 is kept in contact with the bottom end of the cylinder body 301. The weight of the down in the cylinder body 301 is detected by the pressure sensor 311. When the weight of the down reaches the set value, the filling mechanism 1 stops filling. When the transfer component transports and compresses the down, the output end of the third cylinder 309 contracts, causing the transfer plate 310 to swing downward and connect to the port of the guiding mechanism 4, so that the compressed down slides into the guiding mechanism 4.

[0035] Further, as Figure 2 and Figure 8 shown, the shaking component further includes a mounting frame 313 fixedly provided at the top end of the support table 308, slide rails 314 oppositely arranged at the top ends of both sides of the mounting frame 313, and two groups of rollers 315 rotatably provided at both ends of the fixed frame 305. The two groups of rollers 315 are respectively arranged inside the two slide rails 314. The second air cylinder 304 is fixedly connected to the top of the mounting frame 313 through a mounting plate. During the process of the kneading mechanism 3 compressing the down, the rollers 315 roll inside the slide rails 314, and the slide rails 314 cooperate with the rollers 315 and the fixed frame 305 to guide the cylinder body 301. During the process of the transfer component transporting the compressed down, the slide rails 314 fixed at the top end of the mounting frame 313 provide support for the cylinder body 301 through the rollers 315 and the fixed frame 305.

[0036] Further, as Figure 2-5 shown, the humidifying component includes a water pump 316, a water tank connected to the water pump 316, and a third shunt pipe 317, third two-way valves 318 uniformly arranged on the outer side of the third shunt pipe 317, diffusion nozzles connected to the third two-way valves 318, and a humidity sensor for detecting the humidity inside the cylinder body 301. The diffusion nozzles correspond to the cylinder bodies 301 one by one and penetrate through the side walls of the cylinder bodies 301. The humidity sensor is installed on the pressing plate 303 and the detection end of the humidity sensor extends to the bottom end of the pressing plate 303. The water inlet of the water pump 316 is connected to the water tank, and the water outlet of the water pump 316 is connected to the third shunt pipe 317. An exhaust groove 319 is formed at the bottom of the cylinder body 301, and a support net 320 is fixedly arranged inside the exhaust groove 319. A filter membrane 321 is arranged at one end of the support net 320 close to the inside of the cylinder body 301. The humidity inside the cylinder body 301 is detected by the humidity sensor. When the humidity inside the cylinder body 301 is lower than the set value, the corresponding third two-way valve 318 is opened, and the water pump 316 pumps the water in the water tank into the diffusion nozzles through the third shunt pipe 317 and the third two-way valve 318 to humidify the inside of the cylinder body 301. The relative humidity inside the cylinder body 301 is preferably 80%. The water pump 316 is preferably a metering pump, and the metering pump humidifies the inside of the cylinder body 301 according to the humidity condition inside the cylinder body 301. During the process of the first air cylinder 302 compressing the down, the gas and excess water vapor below the pressing plate 303 are discharged from the position of the exhaust groove 319, and the down is intercepted by the support net 320 and the filter membrane 321.

[0037] Further, as Figure 7As shown, the down filling mechanism 1 includes a storage hopper 101 corresponding to the cylinder body 301 one by one, and a discharge valve 102 connected to the storage hopper 101. The upper end of the discharge valve 102 is connected to the air supply system 2. A guide pipe is fixedly provided at the lower end of the discharge valve 102. A through hole 322 is opened on one side of the cylinder body 301 close to the discharge valve 102. The discharge valve 102 is connected to the through hole 322 through the guide pipe. When the pressure sensor 311 detects that the weight of the down reaches the set value, the motor of the discharge valve 102 is turned off.

[0038] Further, as Figure 7 shown, the air supply system 2 includes a fan 201, a three-way valve 202 connected to the fan 201, a first shunt pipe 203 connected to the three-way valve 202, and first double-pass valves 204 uniformly arranged outside the first shunt pipe 203. The first double-pass valves 204 correspond to the discharge valves 102 one by one. A Y-shaped pipe is fixedly provided at the top end of the discharge valve 102. The discharge valve 102 is connected to the first double-pass valve 204 through the Y-shaped pipe. The discharge valve 102 is also connected to the bottom end of the storage hopper 101 through the Y-shaped pipe. The air outlet of the fan 201 is connected to the bottom end of the three-way valve 202. The air inlet of the first shunt pipe 203 is connected to the top end of the three-way valve 202. During the down filling process, the first double-pass valves 204 are opened, and the upper and lower ends of the three-way valve 202 are conducted. The air supply system 2 provides wind power to the Y-shaped pipe through the fan 201, the first shunt pipe 203, and the first double-pass valves 204, so as to pneumatically transport the down at the discharge valve 102. When the motor of the discharge valve 102 is turned off, the fan 201 and the first double-pass valves 204 are also turned off at the same time.

[0039] Further, as Figure 6 shown, the guiding mechanism 4 includes a feeding pipe 401 corresponding to the loading trough 312 one by one, and a feeding tube 402 fixedly provided at the bottom end of the feeding pipe 401. There is a gap between adjacent feeding tubes 402 that can accommodate the bladder cloth. A limiting frame 404 is also fixedly provided at the bottom end of the support platform 308. The limiting frame 404 is used to support the feeding pipe 401. The plurality of feeding pipes 401 are fixed together through a mounting plate.

[0040] Further, as Figure 6 and Figure 7As shown, a second diverter pipe 205 is provided above the side of the discharge pipe 401 near the loading trough 312, and the lower end of the second diverter pipe 205 is connected to a second two-way valve 206 corresponding to the discharge pipe 401 one to one, and a fan-shaped nozzle 403 is fixedly provided at the lower end of the second two-way valve 206. An air inlet corresponding to the fan-shaped nozzle 403 is provided on the discharge pipe 401, and the second diverter pipe 205 is connected to the three-way valve 202. A support frame for supporting the second diverter pipe 205 is fixedly provided on the top of the support platform 308, and the air inlet of the second diverter pipe 205 is connected to the end of the side of the three-way valve 202. An exhaust port is provided on the top of the discharge pipe 401 near the feeding pipe 402, and a position sensor is provided between the air inlet and the exhaust port on the discharge pipe 401, and the detection end of the position sensor extends to the discharge pipe Inside 401, the position sensor is preferably an ultrasonic sensor, and the ultrasonic probe of the ultrasonic sensor is installed on the inner wall of the discharge pipe 401. When the position sensor detects that the compressed down passes through the discharge pipe 401, the second two-way valve 206 opens, and the bottom end of the three-way valve 202 is connected to the port on the side. The air supply system 2 uses the fan 201 to cooperate with the fan-shaped nozzle 403 to blow the compressed down in the discharge pipe 401 to ensure that the compressed down can smoothly pass through the feeding pipe 402 into the bile cloth. The fan-shaped nozzle 403 has upper and lower openings and the area of the upper opening of the fan-shaped nozzle 403 is larger than the area of the lower opening. The Venturi effect is used to improve the blowing effect of the compressed down, and the air in the introduction mechanism 4 can be discharged from the exhaust port on the feeding pipe 402 to avoid the blowing process causing impact on the bile cloth.

[0041] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
