[0024] A mechanical arm is installed on the front of the vertical plate, and the outer side of the nozzle is installed on the mechanical arm.

[0025] The present invention also provides a method for making a seamless down lining, the specific steps of which are as follows:

[0026] S1. The fabric with the tape is conveyed to the right by the conveyor belt, and its placement position corresponds to the through slot and through hole. After conveying to the appropriate position, the conveyor belt is stopped, and the air pump is operated at this time to make the right side conduit and the adsorption box have suction force, and then the fabric on the through hole is adsorbed and fixed;

[0027] S2. Then, the mechanical arm is used to drive the nozzle to move to the right position in the middle of the fabric. Then, the gas discharged by the air pump will be introduced into the U-shaped tube through the left conduit. Then, part of the gas will be blown out from a group of exhaust holes at the bottom in advance, so that the gas will be blown out through the through slot, and then the left side of the fabric will be blown up. During the blowing process, the fabric will rotate along the adsorption fixed part. During the rotation process, it will be folded in coordination with the gas blown out from a group of exhaust holes at the top. At this time, the nozzle will be inside the fabric;

[0028] S3, start the first electric push rod to make the fixed bar drive the two first heating bars and the second heating bar to move downward until the fabric is pressed tightly. At the same time, the second heating bar will compress the hose connected to the nozzle. Then start the first heating bar to hot-melt the front and back sides of the fabric with the adhesive tape to make the fabric into an open bag shape;

[0029] S4. Then the first electric push rod drives the first heating strip and the second heating strip to move to their original positions, and then the two second electric push rods are operated to make the two contact plates contact the inner walls of the fabric opening respectively. At this time, the elastic fabric follows the stretching to cover the opening of the fabric to reduce the leakage of down during the filling process. At the same time, the motor is started to drive the reciprocating block to rotate, so that the grid plate is pushed to the top of the fabric, which has a smoothing effect on the top of the fabric, reduces the bulging deformation of the fabric during the spraying process, increases the adsorption and fixing effect of the right duct on the bottom of the fabric, and can also reduce the increase of excess gas inside the fabric due to deformation. The phenomenon occurs, and then the down spraying device is used to operate, so that the down is introduced into the nozzle along the hose, and then filled into the fabric. The first down spraying can be aimed at filling the folded corners and corners inside the fabric to reduce the hollowing phenomenon at the folded corners and corners. Then the mechanical arm can drive the nozzle to move gradually to the right inside the fabric, and then the down spraying operation is performed again, using segmented down spraying until the fabric reaches a sufficient down content. At the same time, the resistance of the grid plate is used during the down spraying process to achieve a uniform down effect in advance, and the gas generated during the down spraying process will also be discharged in sections to reduce the occurrence of large-scale deformation of the fabric and excessive excess gas inside.

[0030] S5. When the filling is completed, the motor is started again to drive the reciprocating block to rotate. During the movement of the reciprocating block, the grid plate is repeatedly pushed to beat the filled fabric, which can disperse the distribution of the down and effectively discharge the gas in the lining through the gap between the fabric and the resistance plate, reducing the excess gas inside the fabric.

[0031] S6. During the beating process, since the top cross-sections of the two strong magnets at the top are arranged vertically, and the top cross-sections of the two strong magnets at the bottom are arranged horizontally, during the rotation of the reciprocating block, the two metal blocks on the mesh plate will rotate themselves according to the magnetic force of the strong magnets at different positions, so that during the rotation, the position of the mesh on the mesh plate in contact with the fabric changes, so that during the rotation of the reciprocating block, the position of the mesh plate continues to change, reducing the mesh on the mesh plate from being crushed and unevenly dispersed during the continuous beating process;

[0032] S7. After the beating is completed, the two second electric push rods drive the two resistance plates to move to the original position, and then the mechanical arm drives the nozzle to move out from the inside of the fabric. At this time, the first electric push rod is driven again to drive the second heating strip to contact the fabric, and the second heating strip is started to perform edge sealing on the opening of the fabric. Then, the first electric push rod is driven to move to the original position, and the conveyor belt is used again to transport the processed lining bag away.

[0033] Compared with the prior art, the advantages of the present invention are:

[0034] (1) The present invention reduces the phenomenon of down being crushed by the grids on the grid plate during continuous flapping by continuously changing the position of the grid plate. At the same time, it can disperse the amount of down and effectively discharge the gas in the lining through the gap between the fabric and the resistance plate, thereby reducing excess gas inside the fabric.

[0035] (2) The present invention uses an air guide component, a first heating strip, a second heating strip, a spray melting device, a bonding component and a mesh plate to centrally complete the molding, hot pressing, down filling and beating operations of the down lining, effectively saving transportation time and labor costs and improving processing efficiency.

[0046] The reciprocating assembly 4 includes a motor 41, a reciprocating block 42 and two elastic members 43. The motor 41 is installed on the outer side of the vertical plate 3. The output shaft of the motor 41 is fixedly connected to the reciprocating block 42 through a coupling.

[0047] The top two strong magnets 18 are arranged vertically in a plan view, and the bottom two strong magnets 18 are arranged horizontally in a plan view.

[0048] In the present invention, the arrangement of the base frame 1 is utilized to facilitate supporting the entire device, and the fabric is transported by the conveyor belt 2. After being transported to a suitable position, the conveyor belt 2 is stopped, and the air pump 131 in the air guide component 13 is operated so that the right-side conduit 132 and the adsorption box 133 have suction force, and then the fabric on the through hole 10 is adsorbed and fixed, and then the nozzle 15 on the velvet spraying device 14 is moved to the right position of the middle part of the fabric, and then the gas discharged by the air pump 131 is introduced into the U-shaped tube 134 through the left-side conduit 132, and then part of the gas is blown out from a group of exhaust holes 19 at the bottom in advance, so that the gas is blown out through the through groove 9, and then the left side of the fabric is blown up. During the blowing process, the fabric will rotate along the adsorption and fixing position, and during the rotation process, the top The gas blown out of a group of exhaust holes 19 in the upper part folds it. At this time, the nozzle 15 will be inside the fabric. Then the first electric push rod 5 is started to operate, so that the fixing strip 6 drives the two first heating strips 7 and the second heating strip 8 to move downward until the fabric is pressed tightly. At the same time, the second heating strip 8 will compress the hose connected to the nozzle 15. Then the first heating strip 7 is started to operate, and the front and back sides of the fabric are hot-melted and fixed with the tape to make the fabric into an open cloth bag shape. Then the first electric push rod 5 drives the first heating strip 7 and the second heating strip 8 to move to the original position. At this time, the fitting component 17 is used to operate to cover the opening of the fabric to reduce the leakage of down during the filling process. At the same time, the motor 41 is started to drive the reciprocating block 42 to rotate, so that the grid The plate 11 is pushed to the top of the fabric, which has a smoothing effect on the top of the fabric, reduces the bulging deformation of the fabric during the spraying process, increases the adsorption and fixing effect of the right duct 132 on the bottom of the fabric, and reduces the increase of excess gas inside the fabric due to deformation. Then, the spraying device 14 is operated to guide the down along the hose into the nozzle 15, and then fill it into the fabric. The first spraying can be used to fill the folded corners and corners inside the fabric to reduce the hollowing phenomenon at the folded corners and corners. Then, the mechanical arm 16 can drive the nozzle 15 to move gradually to the right inside the fabric, and then the spraying operation is performed again, using segmented spraying until the fabric reaches a sufficient down content. At the same time, the resistance of the grid plate 11 is used during the spraying process. , the uniform down effect is achieved in advance, and the gas generated during the down spraying process will also be discharged in sections, reducing the occurrence of large-scale deformation of the fabric and excessive internal excess gas. Then, the motor 41 in the reciprocating assembly 4 is started again to drive the reciprocating block 42 to rotate. During the movement of the reciprocating block 42, the elastic member 43 will ensure the stability of the grid plate 11. Then the reciprocating block 42 will repeatedly push the grid plate 11 to beat the filled fabric. During the beating process, since the top-view cross-sections of the two strong magnets 18 at the top are arranged up and down, and the top-view cross-sections of the two strong magnets 18 at the bottom are arranged left and right, during the rotation of the reciprocating block 42, the two metal blocks 12 on the grid plate 11 will rotate themselves according to the magnetic influence of the strong magnets 18 at different positions.Therefore, during the rotation process, the position where the grid on the grid plate 11 contacts the fabric changes, so that during the rotation process of the reciprocating block 42, the position of the grid plate 11 continues to change, reducing the phenomenon of the down being crushed by the grid on the grid plate 11 during the continuous beating process, dispersing the distribution of the down amount, and effectively discharging the gas in the lining along the gap between the fabric and the contact plate 171, reducing the excess gas inside the fabric. When the beating is completed, the two second electric push rods 172 drive the two contact plates 171 to move to the original position. Then the mechanical arm 16 drives the nozzle 15 to move out from the inside of the fabric, and then drives the first electric push rod 5 again to drive the second heating strip 8 to contact the fabric, and starts the second heating strip 8 to perform edge sealing on the opening of the fabric. During the processing, the pressing temperature of the first heating strip 7 and the second heating strip 8 is between 120℃ and 140℃, with a high peeling fastness to ensure that the composite fabric is not easy to fall off and prevent lint. Then drive the first electric push rod 5 to move to the original position, and use the conveyor belt 2 again to transport the processed lining bag away.

[0049] See also Figure 1-3 , wherein: the elastic member 43 includes a fixed tube 431, a sliding rod 432 and a spring 433, the fixed tube 431 is fixedly connected to the outside of the support plate, one end of the spring 433 is fixedly connected to the inside of the fixed tube 431, one end of the sliding rod 432 passes through and is slidably connected to the inside of the fixed tube 431, the other end of the spring 433 is fixedly connected to the sliding rod 432, and the other end of the sliding rod 432 is rotatably connected to the inside of the grid plate 11.

[0050] In the present invention, the setting of the fixed tube 431 and the sliding rod 432 is utilized to limit the mesh plate 11 without affecting its up and down movement. Combined with the elastic force of the spring 433, after the mesh plate 11 moves downward, an upward pulling force is provided to the sliding rod 432, so that the mesh plate 11 can be reset, which is convenient for repeated beating operations.

[0051] See also Figure 1-3 , wherein: an annular groove is opened on the top of the grid plate 11, and one end of the sliding rod 432 is rotatably connected to the inside of the annular groove.

[0052] In the present invention, the annular groove is provided so that the mesh plate 11 can rotate normally without affecting the connection between the sliding rod 432 and the mesh plate 11, thereby improving the beating effect.

[0053] See also Figure 1 , wherein: a control cabinet 20 is installed on the front side of the vertical plate 3.

[0056] In the present invention, two second electric push rods 172 are operated to make the two contact plates 171 contact the inner wall of the fabric opening respectively. At this time, the elastic fabric 173 is stretched to cover the fabric opening, thereby reducing the leakage of down during the filling and flapping process.

[0057] See also Figure 1-4 , wherein: the bottom group of exhaust holes 19 are located below the through slot 9, and the top group of exhaust holes 19 are all oriented in an inclined shape.

[0058] In the present invention, the bottom group of exhaust holes 19 are located below the through groove 9, so that the gas can blow one end of the fabric to move when it is discharged. The directions of the top group of exhaust holes 19 are all inclined, which can provide a force for the fabric to move to the right during its movement, thereby ensuring its folding effect and reducing the occurrence of wrinkles during the folding process.

[0059] See also Figure 1-5 , wherein: a mechanical arm 16 is installed on the front of the vertical plate 3 , and the outer side of the nozzle 15 is installed on the mechanical arm 16 .

[0060] In the present invention, the mechanical arm 16 is used to control the position of the nozzle 15, which is more convenient and intelligent.

[0061] The present invention also provides a method for making a seamless down lining, the specific steps of which are as follows:

[0062] S1, convey the fabric with tape to the right by the conveyor belt 2, and place it in a position corresponding to the through slot 9 and the through hole 10. After conveying to a suitable position, stop the conveyor belt 2, and use the air pump 131 to operate so that the right side conduit 132 and the adsorption box 133 have suction force, and then adsorb and fix the fabric on the through hole 10;

[0063] S2, then use the mechanical arm 16 to drive the nozzle 15 to move to the right position in the middle of the fabric, then the gas discharged by the air pump 131 will be introduced into the U-shaped tube 134 through the left conduit 132, and then part of the gas will be blown out from the bottom group of exhaust holes 19 in advance, so that the gas is blown out through the through groove 9, and then the left side of the fabric will be blown up. During the blowing process, the fabric will rotate along the adsorption fixed part. During the rotation process, it will be folded in coordination with the gas blown out from the top group of exhaust holes 19. At this time, the nozzle 15 will be inside the fabric;

[0064] S3, start the first electric push rod 5 to operate, so that the fixing bar 6 drives the two first heating bars 7 and the second heating bar 8 to move downward until the fabric is pressed tightly. At the same time, the second heating bar 8 will compress the hose connected to the nozzle 15, mainly to cooperate with the second heating bar 8 to not be blocked by the part connected to the nozzle 15 during the downward pressing process. Then start the first heating bar 7 to operate, and cooperate with the tape to hot-melt fix the front and back sides of the fabric, so that the fabric is in the shape of an open cloth bag;

[0065] S4, then the first electric push rod 5 drives the first heating strip 7 and the second heating strip 8 to move to their original positions, and then the two second electric push rods 172 are operated to make the two contact plates 171 respectively contact the inner walls of the fabric opening. At this time, the elastic fabric 173 follows the stretching to cover the fabric opening to reduce the leakage of down during the filling process. At the same time, the motor 41 is started to drive the reciprocating block 42 to rotate, so that the grid plate 11 is pushed to the top of the fabric, which has a smoothing effect on the top of the fabric, reduces the bulging deformation of the fabric during the spraying process, and increases the adsorption and fixing effect of the right duct 132 on the bottom of the fabric. At the same time, it can reduce the increase of excess gas inside the fabric due to deformation. Then, the down spraying device 14 is operated to guide the down along the hose into the nozzle 15, and then fill it into the fabric. For the first down spraying, the nozzle 15 can be sent to the leftmost side of the fabric through the mechanical arm 16, and the folded corners and corners inside the fabric can be filled to reduce the hollowing phenomenon at the folded corners and corners. Then, the mechanical arm 16 can drive the nozzle 15 to move gradually to the right inside the fabric, and then the down spraying operation is performed again, using segmented down spraying until the fabric reaches a sufficient down content. At the same time, during the down spraying process, the mesh plate 11 is used to resist to achieve a uniform down effect in advance, and the gas generated during the down spraying process will also be discharged in segments to reduce the occurrence of large-scale deformation of the fabric and excessive excess gas inside.

[0066] S5. When the filling is completed, the motor 41 is started again to drive the reciprocating block 42 to rotate. During the movement of the reciprocating block 42, the grid plate 11 is repeatedly pushed to beat the filled fabric, which can disperse the distribution of the down and effectively discharge the gas in the lining through the gap between the fabric and the abutment plate 171, thereby reducing the excess gas inside the fabric.

[0067] S6. During the beating process, since the top cross-sections of the two strong magnets 18 at the top are arranged vertically, and the top cross-sections of the two strong magnets 18 at the bottom are arranged horizontally, during the rotation of the reciprocating block 42, the two metal blocks 12 on the mesh plate 11 will rotate themselves according to the magnetic force of the strong magnets 18 at different positions, so that during the rotation, the position of the mesh on the mesh plate 11 in contact with the fabric changes, so that during the rotation of the reciprocating block 42, the position of the mesh plate 11 continues to change, reducing the mesh on the mesh plate 11 from being crushed and unevenly dispersed during the continuous beating process;

[0068] S7. After the beating is completed, the two second electric push rods 172 drive the two contact plates 171 to move to the original position, and then the robot arm 16 drives the nozzle 15 to move out from the inside of the fabric. At this time, the first electric push rod 5 is driven again to drive the second heating strip 8 to contact the fabric, and the second heating strip 8 is started to perform edge sealing on the opening of the fabric. Then, the first electric push rod 5 is driven to move to the original position, and the conveyor belt 2 is used again to transport the processed lining bag away.

[0069] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

7. A method for producing a seamless down lining using the production equipment for a seamless down lining according to any one of claims 1 to 6, the specific steps being as follows: S1, conveying the fabric with the adhesive tape to the right by the conveyor belt (2), and placing it at a position corresponding to the through groove (9) and the through hole (10). After conveying it to a suitable position, the conveyor belt (2) is stopped, and the air pump (131) is operated to make the right side conduit (132) and the adsorption box (133) have suction force, and then the fabric on the through hole (10) is adsorbed and fixed; S2, then use the mechanical arm (16) to drive the nozzle (15) to move to the right position in the middle of the fabric, and then the gas discharged by the air pump (131) will be introduced into the inside of the U-shaped tube (134) through the left conduit (132), and then part of the gas will be blown out from the bottom group of exhaust holes (19) in advance, so that the gas is blown out through the through groove (9), and then the left side of the fabric will be blown up. During the blowing process, the fabric will rotate along the adsorption fixing part. During the rotation process, it will be folded in coordination with the gas blown out from the top group of exhaust holes (19). At this time, the nozzle (15) will be inside the fabric; S3, start the first electric push rod (5) to operate, so that the fixing strip (6) drives the two first heating strips (7) and the second heating strip (8) to move downward until the fabric is pressed tightly. At the same time, the second heating strip (8) will compress the hose connected to the nozzle (15), and then start the first heating strip (7) to operate, and cooperate with the tape to hot-melt fix the front and back sides of the fabric, so that the fabric is in the shape of an open cloth bag; S4. The first electric push rod (5) then drives the first heating strip (7) and the second heating strip (8) to move to their original positions. The two second electric push rods (172) are then operated to cause the two contact plates (171) to contact the inner walls of the fabric openings respectively. At this time, the elastic fabric (173) follows the stretching to cover the fabric openings, thereby reducing the leakage of down during the filling process. At the same time, the motor (41) is started to drive the reciprocating block (42) to rotate, so that the grid plate (11) is pushed to the top of the fabric, which has a smoothing effect on the top of the fabric, reduces the bulging deformation of the fabric during the down spraying process, increases the adsorption and fixing effect of the right duct (132) on the bottom of the fabric, and can also reduce the fabric from being deformed due to shape deformation. The phenomenon of excess gas increasing inside the fabric is caused by the change of the down. Subsequently, the down spraying device (14) is operated to guide the down along the hose into the nozzle (15) and then fill it into the fabric. The first down spraying can be targeted at the folded corners and corners inside the fabric to reduce the hollowing phenomenon at the folded corners and corners. Subsequently, the mechanical arm (16) can drive the nozzle (15) to gradually move to the right inside the fabric. Subsequently, the down spraying operation is performed again, using segmented down spraying until the fabric reaches a sufficient down content. At the same time, the mesh plate (11) is used in the down spraying process to achieve a uniform down effect in advance. The gas generated during the down spraying process will also be discharged in segments, reducing the occurrence of large-scale deformation of the fabric and excessive excess gas inside. S5. When the filling is completed, the motor (41) is started again to drive the reciprocating block (42) to rotate. During the movement of the reciprocating block (42), the mesh plate (11) is repeatedly pushed to beat the filled fabric, thereby dispersing the amount of down and effectively discharging the gas in the lining through the gap between the fabric and the abutment plate (171), thereby reducing the excess gas inside the fabric. S6. During the beating process, since the top cross-sections of the two strong magnets (18) at the top are arranged vertically, and the top cross-sections of the two strong magnets (18) at the bottom are arranged horizontally, during the rotation of the reciprocating block (42), the two metal blocks (12) on the mesh plate (11) will rotate according to the magnetic force of the strong magnets (18) at different positions, so that during the rotation, the position of the mesh on the mesh plate (11) in contact with the fabric changes, so that during the rotation of the reciprocating block (42), the position of the mesh plate (11) continues to change, thereby reducing the phenomenon of squashing of down and uneven dispersion of down caused by the mesh on the mesh plate (11) during the continuous beating process; S7. After the beating is completed, the two second electric push rods (172) drive the two contact plates (171) to move to their original positions, and then the mechanical arm (16) drives the nozzle (15) to move out from the inside of the fabric. At this time, the first electric push rod (5) is driven again to drive the second heating strip (8) to contact the fabric, and the second heating strip (8) is started to perform edge sealing on the opening of the fabric. Then, the first electric push rod (5) is driven to move to its original position, and the conveyor belt (2) is used again to transport the processed lining bag away.
