Description

Technical Field

[0001] This invention relates to the field of garment manufacturing technology, and in particular to a down-filling composite device and method for slim-fit thermal shirts based on PVC boards. Background Technology

[0002] In the garment manufacturing industry, especially in the production of thermal shirts, the down filling process is one of the key steps. For slim-fit thermal shirts based on PVC boards, the uniformity and shaping effect of the down filling directly affect the shirt's warmth and appearance.

[0003] Traditionally, when filling shirt fabric with down, the garment is made first, and then the filling holes are left for filling. This method tends to result in a bulky appearance and often lacks effective smoothing techniques. As a result, the down is unevenly distributed within the fabric, and there are often localized piles or missing down feathers. This not only affects the shirt's warmth but also makes the shirt look uneven, reducing the product's market competitiveness.

[0004] Meanwhile, after filling with down, how to properly shape the down and shirt fabric is also a problem that urgently needs to be solved. If the shaping effect is not good, the down is prone to shifting during subsequent wear and use, further damaging the warmth and appearance.

[0005] While existing down filling equipment can achieve down filling to a certain extent, it has significant shortcomings in down leveling and heat pressing, and cannot meet the high-quality production requirements of slim-fit thermal shirts based on PVC boards.

[0006] To address the aforementioned issues, this invention proposes a down-filling composite device and method for a slim-fit thermal shirt based on PVC board. Summary of the Invention

[0007] This invention provides a down-filling composite equipment and method for slim-fit thermal shirts based on PVC boards, which solves the shortcomings of uneven down filling and poor shaping effect in traditional thermal shirt production.

[0008] This invention provides the following technical solution:

[0009] A down-filling composite device for a slim-fit thermal shirt based on PVC board, comprising:

[0010] The chassis has a tray fixedly installed inside, and the top of the tray has multiple anti-slip protrusions arranged in a matrix at equal intervals.

[0011] The drive mechanism is mounted on the chassis, with one side extending into the chassis and connecting to the inner wall of the chassis.

[0012] The adjustment mechanism, installed on the drive mechanism, includes a gantry frame, a fixing ring fixedly fitted to the gantry frame, a support frame fixed to one side of the fixing ring, a transmission component installed on the top of the support frame, and an L-shaped box installed on one side of the transmission component. The bottom side of the L-shaped box is fixedly connected to a PVC suction box. Multiple suction holes are evenly spaced on the inner wall of the bottom of the PVC suction box. The diameter of the suction holes gradually increases from the center of the PVC suction box to both sides, and is used to flatten the down filling the shirt fabric by suction.

[0013] The hot pressing mechanism, installed on the adjusting mechanism, includes two mounting plates symmetrically fixed to the other side of the PVC suction box, an adjusting shaft rotatably connected to the two mounting plates, two fixed plates fixedly mounted on the adjusting shaft, and a pressure roller rotatably connected to the two fixed plates. The pressure roller has a hollow structure and a spiral heating wire is fixedly installed inside, which is used to hot press and shape the flattened down and shirt fabric.

[0014] The suction mechanism, installed on one side of the casing and connected to the adjustment mechanism, is used to extract gas from the PVC suction box, so that the PVC suction box is in a suction state.

[0015] In one possible design, the transmission assembly includes:

[0016] A stepper motor is fixedly mounted on the top of the support frame, and its output shaft extends into the support frame and is fixedly mounted with an adjusting screw.

[0017] The guide rail is fixedly installed on the inner wall of one side of the support frame;

[0018] The adjusting plate is slidably connected to the guide rail, and an adjusting nut is fixedly installed on the top. One side is fixedly connected to the top of the L-shaped box.

[0019] The bottom end of the adjusting screw passes through the adjusting nut and the adjusting plate and is rotatably connected to the inner wall of the bottom of the support frame. It is also threadedly connected to the adjusting nut. By starting the stepper motor, the adjusting screw is driven to rotate, and under the action of thread transmission, the adjusting plate is driven to move longitudinally to adjust the height of the L-shaped box and the PVC suction box.

[0020] In one possible design, adjustment components are mounted at both ends of the adjustment shaft, and the adjustment components include:

[0021] The transmission rod is fixedly installed at one end of the adjusting shaft;

[0022] The connecting shaft is fixedly installed on the top side of the transmission rod.

[0023] A collar is rotatably connected to one end of the connecting shaft.

[0024] The connecting rod slides through the collar;

[0025] The tow bar is fixedly installed at the bottom end of the connecting rod.

[0026] The support ring is slidably sleeved on the drag rod and fixedly installed on one side of the top of the PVC suction box.

[0027] The insert rod slides through the inner wall of the top of the support ring and is movably inserted into the slot on the drag rod;

[0028] A tension spring is sleeved on the outside of the insertion rod, with its top and bottom ends fixedly connected to the top of the insertion rod and the top of the support ring respectively via hooks.

[0029] By operating the adjustment component, the adjustment shaft can be rotated to adjust the height of the pressure roller, so that it comes into contact with the shirt fabric for heat pressing.

[0030] In one possible design, the drive mechanism includes:

[0031] The sliding cover is fixedly installed on both sides of the chassis;

[0032] The threaded plate is slidably connected inside the sliding cover;

[0033] The transmission screw is rotatably connected to the inner wall of one side of the slide cover, and one end extends to the outside of the chassis, passes through the threaded plate and is threadedly connected to the threaded plate.

[0034] The drive motor is fixedly installed on the inner wall of one side of the chassis, and the output shaft extends to the outside of the chassis and is fixedly fitted with an active synchronous pulley.

[0035] The driven synchronous pulley is fixedly mounted on the transmission screw at one end of the outer side of the housing;

[0036] The synchronous belt is fitted onto the driving synchronous pulley and two driven synchronous pulleys.

[0037] By starting the drive motor to drive the active synchronous pulley to rotate, the synchronous belt drives the two transmission screws to rotate, which in turn drives the gantry frame to move laterally, causing the PVC suction box and pressure roller to move laterally, so as to fully level and heat-press the down inside the shirt.

[0038] In one possible design, two limiting wheels are symmetrically rotatably connected to one side of the chassis, located on both sides of the synchronous belt, to limit the contraction of the synchronous belt, so that the wrap angle of the synchronous belt at the driving synchronous wheel and the two driven synchronous wheels reaches 180°, thus avoiding transmission failure and slippage.

[0039] In one possible design, the attraction mechanism includes:

[0040] The support tube penetrates the inner wall of the top of the L-shaped box and is fixedly connected.

[0041] The connector is rotatably attached to the top of the support tube;

[0042] Corrugated flexible hose, one end of which is fixedly connected to the connector;

[0043] The vacuum pump is fixedly installed on the outside of the casing, and a connecting box is fixedly installed on the suction end;

[0044] The bend is rotatably connected to the inner wall of the top of the connecting box, and its top end is fixedly connected to the other end of the corrugated hose.

[0045] By activating the vacuum pump to generate suction, the PVC suction box maintains suction, adsorbing and leveling the down inside the shirt. The gas is discharged through the suction hole, connecting pipe, L-shaped box, support pipe, connector, corrugated hose, bend, connecting box and vacuum pump, creating a negative pressure field distribution that dynamically decreases from the center to the edge, solving the problem of blind spots in the down filling at the corners.

[0046] In one possible design, multiple pins are also included. Multiple insertion holes are equally spaced in a matrix on the support plate. The pins pass through the corresponding insertion holes. An arc-shaped protrusion is provided below the support plate, and a buffer groove is provided. A fixing screw is fixedly installed at the top. A fixing nut is threaded on the fixing screw, and a pressure plate is fixedly installed on the fixing nut.

[0047] After placing the shirt fabric and down on the tray, insert the pin and turn the fixing nut to move the pressure plate downwards to press and position the edges of the shirt fabric.

[0048] In one possible design, the pressure roller is rotatably connected to two fixed plates via an adjusting shaft, and heat-presses and shapes the down inside the shirt after the spiral heating wire is energized and heated.

[0049] In one possible design, the bottom of the gantry frame is fixedly connected to the top of two threaded plates, and moves laterally under the drive of the drive mechanism to achieve full leveling and hot pressing of the down inside the shirt by the PVC suction box and pressure roller.

[0050] The method of using the down filling composite equipment for a PVC-based slim-fit thermal shirt includes the following steps:

[0051] S1. Fabric positioning: The inner lining fabric, down, and outer fabric used to make the down shirt are stacked on the pallet, and the down is wrapped by the inner lining fabric and the outer fabric; multiple pins are inserted into the corresponding holes to achieve a tight fit; the fixing nut is rotated, and the pressure plate is driven to move down through the thread transmission with the fixing screw, and the pressure plate is used to press and fix the edges and corners of the shirt fabric.

[0052] S2. Adsorption height adjustment: Start the stepper motor to drive the adjusting screw to rotate, and drive the adjusting plate to move longitudinally through the thread transmission with the adjusting nut, thereby adjusting the height of the L-shaped box, so that the PVC suction box rises to a position that keeps in contact with the fabric on the upper layer.

[0053] S3. Down Negative Pressure Leveling: The vacuum pump is started to generate suction, which causes the PVC suction box to adsorb the down in the shirt for leveling; gas is drawn into the PVC suction box through the air hole, flows through the connecting pipe, L-shaped box, connector, corrugated hose, bend, connecting box and is discharged by the vacuum pump to achieve continuous suction; the suction force at the bottom center of the PVC suction box is greater than that on both sides of the bottom, forming a negative pressure field distribution that dynamically decreases from the center to the edge, eliminating blind spots in the corner down filling.

[0054] S4. Lateral Movement and Overall Leveling: Start the drive motor to drive the active synchronous pulley to rotate, and drive the two transmission screws to rotate through the transmission cooperation of the synchronous belt and the two driven synchronous pulleys; drive the gantry frame to move laterally through the thread transmission with the corresponding thread plate, and drive the PVC suction box to move laterally synchronously during the down suction and leveling process to achieve overall down suction and leveling; when the PVC suction box moves laterally, the guide strip at its bottom is used to pre-guide the shirt fabric to ensure smooth movement.

[0055] S5. Height Adjustment and Locking of Hot Pressing Mechanism: After the down is leveled, pull the insert rod upward to disengage it from the slot; push the drag rod laterally to move it, and under the sliding cooperation of the connecting rod and the collar, drive the transmission rod to rotate upward in an arc, thereby driving the adjusting shaft to rotate and causing the pressure roller to rotate downward to the position of pressing the shirt fabric; when the pressure roller is in place, release the insert rod, and the tension spring under force drives the insert rod downward to lock into the corresponding slot, positioning the drag rod and thus locking the pressing height of the pressure roller.

[0056] S6. Hot pressing and shaping: The spiral heating wire is energized to heat the pressure roller; the drive motor is started to drive the gantry frame to move laterally, which in turn drives the pressure roller, which is in a high-temperature state, to move laterally synchronously; the high-temperature pressure roller is used to hot press the down inside the shirt to achieve down shaping.

[0057] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the invention.

[0058] Beneficial effects: In this invention, the drive mechanism can drive the active synchronous pulley to rotate by starting the drive motor. At this time, under the transmission cooperation of the synchronous belt and the two driven synchronous pulleys, the two transmission screws can be driven to rotate. Under the thread transmission action with the corresponding threaded plate, the gantry frame can be driven to move laterally. This allows the PVC suction box and pressure roller to move laterally when the down in the shirt is attracted, leveled and pressed. This enables the comprehensive attraction, leveling and hot pressing of the down in the shirt.

[0059] In this invention, the L-shaped box can be used to provide longitudinal sliding support for the PVC suction box through the adjustment mechanism. In this way, the PVC suction box can be driven by the driving force of the transmission component to adjust its longitudinal height. This allows the PVC suction box to be moved downwards to contact the shirt fabric, which facilitates the attraction and leveling of the down filling the shirt fabric.

[0060] In this invention, the hot pressing mechanism can be set up so that after the down inside the shirt fabric is attracted and leveled, the two adjusting components can be operated to drive the adjusting shaft to rotate, thereby moving the pressure roller downward so that the pressure roller is in contact with the shirt fabric. Then, the spiral heating wire is energized to heat the pressure roller, so that the pressure roller in the high temperature state can be used to hot press the down inside the shirt and shape the down.

[0061] In this invention, the suction mechanism can generate suction by activating a vacuum pump, which maintains the suction in the PVC suction box, allowing it to adsorb and level the down feathers inside the shirt. After the gas is drawn into the PVC suction box through the air vent, it passes through the connecting pipe, L-shaped box, connector, corrugated hose, bend, connecting box, and vacuum pump, thus achieving continuous suction. Furthermore, the suction force at the bottom center of the PVC suction box is greater than that on the bottom sides, creating a negative pressure field distribution that dynamically decreases from the center to the edge, effectively solving the problem of blind spots in edge and corner down filling that exists in traditional planar adsorption.

[0062] This invention uses a pre-spreading method to fill down into the shirt fabric, and then uses negative pressure suction to easily flatten the down. After flattening the down, it can be heat-pressed to achieve the purpose of heat-pressing and shaping the down, thereby ensuring that the produced shirt has both warmth and a slimming effect.

[0073] The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0074] In the description of the embodiments of the present invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the devices are connected to each other and their relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of the present invention, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of the present invention.

[0075] In one embodiment: Refer to Figure 1-8 A composite device includes a housing 1, inside which a support plate 2 is bolted and fixed. The top of the support plate 2 has multiple anti-slip protrusions 3 integrally formed in a matrix pattern with equal spacing. A drive mechanism is mounted on the housing 1, with one side extending into the housing 1 and connecting to one inner wall of the housing 1. The composite device also includes an adjustment mechanism mounted on the drive mechanism, which is equipped with a PVC suction box 14. Multiple suction holes are evenly spaced on the bottom inner wall of the PVC suction box 14, with the diameter of the holes increasing sequentially from the center of the PVC suction box 14 to both sides, using suction to flatten the down filling the shirt fabric. A heat-pressing mechanism is also mounted on the adjustment mechanism, enabling heat pressing and shaping of the down and shirt fabric after flattening. The suction mechanism, connected to the adjustment mechanism, is mounted on one side of the housing 1 and used to extract gas from the PVC suction box 14, thus putting the PVC suction box 14 in a suction state.

[0076] like Figure 1-3As shown, the adjustment mechanism includes a gantry frame 7, which is connected to the drive mechanism. A fixing ring 8 is fixedly fitted on the gantry frame 7. A support frame 9 is fixedly installed on one side of the fixing ring 8 by welding. A transmission component is installed on the top of the support frame 9. The bottom of the transmission component extends into the support frame 9 and is connected to the inner wall of the support frame 9. An L-shaped box 12 located on one side of the support frame 9 is installed on one side of the transmission component. A PVC suction box 14 is fixedly connected to the bottom side of the L-shaped box 12 by welding. A connecting pipe 19 is fixedly installed on the inner wall of the bottom side of the L-shaped box 12 by welding. The bottom end of the connecting pipe 19 extends into the PVC suction box 14 and is fixedly connected to the top inner wall of the PVC suction box 14 by welding. The L-shaped box 12 is connected to the suction mechanism. A limit frame 13 is fixedly installed on the bottom side of one side of the support frame 9 by welding. The L-shaped box 12 passes through the limit frame 13 and is slidably connected to the inner wall of the limit frame 13. A guide strip 15 is fixedly installed on the bottom side of one side of the PVC suction box 14 by welding. The L-shaped box 12 provides longitudinal sliding support for the PVC suction box 14, thereby enabling the PVC suction box 14 to be driven by the transmission component to adjust its longitudinal height. This allows the PVC suction box 14 to be moved downwards to contact the shirt fabric, facilitating the attraction and leveling of the down filling the shirt fabric.

[0077] like Figure 3 As shown, the transmission assembly includes a stepper motor 16 bolted to the top of the support frame 9. The output shaft of the stepper motor 16 extends into the support frame 9 and is fixedly mounted with an adjusting screw 17 via a coupling. A guide rail 10 is welded to the inner wall of one side of the support frame 9. An adjusting plate 11 is slidably connected to the guide rail 10. An adjusting nut 18 is welded to the top of the adjusting plate 11. The bottom end of the adjusting screw 17 passes through the adjusting nut 18 and the adjusting plate 11, and is rotatably connected to the bottom inner wall of the support frame 9 via a bearing. The adjusting screw 17 is threadedly connected to the adjusting nut 18. One side of the adjusting plate 11 is welded to the top of one side of the L-shaped box 12. By starting the stepper motor 16, the adjusting screw 17 is rotated. Under the threaded transmission with the adjusting nut 18, the adjusting plate 11 can be moved longitudinally, thereby adjusting the height of the L-shaped box 12. Furthermore, the PVC suction box 14 can be adjusted to a specified height.

[0078] like Figure 3-6As shown, the hot pressing mechanism includes two mounting plates 26 symmetrically welded and fixedly installed on the other side of the PVC suction box 14. A common adjusting shaft 27 is rotatably connected through the two mounting plates 26. Two fixing plates 28 are symmetrically fixedly mounted on the adjusting shaft 27 between the two mounting plates 26. A pressure roller 29 is rotatably connected to the two fixing plates 28 via bearings. The pressure roller 29 has a hollow structure, and a spiral heating wire 30 is fixedly installed inside the pressure roller 29 by bolts. Adjusting components are installed at both ends of the adjusting shaft 27, with one side of the adjusting components installed on the top of the PVC suction box 14. After the down feathers inside the shirt fabric are attracted and leveled, the adjusting shaft 27 is rotated by operating the two adjusting components, thereby moving the pressure roller 29 downwards to maintain contact with the shirt fabric. Then, the spiral heating wire 30 is energized, heating the pressure roller 29. The high-temperature pressure roller 29 then heats the down feathers inside the shirt, shaping them.

[0079] like Figure 6 As shown, the adjustment assembly includes a transmission rod 35 fixedly installed at one end of the adjustment shaft 27 by welding. A connecting shaft 36 is fixedly installed at the top of one side of the transmission rod 35 by welding. A collar 34 is rotatably connected to one end of the connecting shaft 36 by a bearing. A connecting rod 33 is slidably connected through the collar 34. A drag rod 32 is fixedly installed at the bottom end of the connecting rod 33 by welding. A support ring 31 is slidably sleeved on the drag rod 32. The support ring 31 is fixedly installed on the top side of the PVC suction box 14 by welding. Two slots 37 are opened on the drag rod 32. An insert rod 38 is slidably connected through the top inner wall of the support ring 31. The insert rod 38 is movably inserted into the two slots 37 respectively. A tension spring 39 is sleeved on the insert rod 38 and located above the support ring 31. The top and bottom ends of the tension spring 39 are fixedly connected to the top of the insert rod 38 and the top of the support ring 31 by hooks respectively. By pulling the insert rod 38 upwards to move it out of the slot 37, the drag rod 32 can be pushed to move laterally. At this time, under the sliding engagement of the connecting rod 33 and the collar 34, the transmission rod 35 can be driven to rotate upwards in an arc shape, which can drive the adjusting shaft 27 to rotate and adjust the pressure roller 29 downwards. When the pressure roller 29 moves to press the shirt fabric, the slot 37 on the other side can correspond to the position of the insert rod 38, and the insert rod 38 can be released. The tension spring 39 under force can drive the insert rod 38 downwards to move into the corresponding slot 37, positioning the drag rod 32. Furthermore, the height of the pressure roller 29 can be limited.

[0080] like Figure 7As shown, the drive mechanism includes sliding covers 5 fixedly mounted on both sides of the housing 1 by bolts. Threaded plates 6 are slidably connected inside the sliding covers 5. The bottom of the gantry frame 7 is fixedly connected to the top of the two threaded plates 6 by welding. A transmission screw 40 is rotatably connected to one inner wall of the sliding cover 5 by bearings. One end of the transmission screw 40 extends to the outside of the housing 1. The transmission screw 40 passes through the threaded plates 6 and is threadedly connected to the threaded plates 6. A drive motor 41 is fixedly mounted on one inner wall of the housing 1 by bolts. The output shaft of the drive motor 41 extends to the outside of the housing 1 and is fixedly fitted with a driving synchronous pulley 42. A driven synchronous pulley 43 located on the outside of the housing 1 is fixedly fitted on the transmission screw 40. The driving synchronous pulley 42 and the two driven synchronous pulleys 43 are driven by the same synchronous belt 44. The synchronous belt (44) is a polyurethane steel wire core structure with an elongation rate of ≤2%. By starting the drive motor 41, the active synchronous pulley 42 is driven to rotate. At this time, under the transmission cooperation between the synchronous belt 44 and the two driven synchronous pulleys 43, the two transmission screws 40 can be driven to rotate. Under the thread transmission action with the corresponding threaded plate 6, the portal frame 7 can be driven to move laterally. When the down in the shirt is attracted, leveled and pressed, the PVC attraction box 14 and the pressure roller 29 can be driven to move laterally, so as to achieve comprehensive attraction, leveling and hot pressing of the down in the shirt.

[0081] like Figure 1 As shown, two limiting wheels 45 are symmetrically rotatably connected to one side of the chassis 1. The two limiting wheels 45 are located on both sides of the synchronous belt 44, and are used to limit the contraction of the synchronous belt 44, so that the wrap angle of the synchronous belt 44 at the driving synchronous pulley 42 and the two driven synchronous pulleys 43 reaches 180°, thus avoiding problems such as transmission failure and slippage.

[0082] This application can be used in the field of garment production technology, or in other fields applicable to this application.

[0083] In another embodiment: Reference Figure 1 and 5An improvement based on Embodiment 1: A down-filling composite device for a slim-fit thermal shirt based on PVC board, which is applied to the field of garment production technology. The suction mechanism includes a support pipe 20 that penetrates the top inner wall of an L-shaped box 12 and is fixedly connected to the top inner wall of the L-shaped box 12 by welding. The top end of the support pipe 20 is rotatably connected to a connector 21 via a bearing. One end of the connector 21 is fixedly connected to a corrugated hose 22. A vacuum pump 23 is fixedly installed on the outside of the machine box 1 by bolts. A connecting box 24 is fixedly installed on the suction end of the vacuum pump 23 by bolts. A bent pipe 25 is rotatably connected through the top inner wall of the connecting box 24. The top end of the bent pipe 25 is fixedly connected to one end of the corrugated hose 22. By activating the vacuum pump 23, suction is generated, which keeps the PVC suction box 14 in a state of suction. This allows the down feathers inside the shirt to be adsorbed and leveled. After the gas is drawn into the PVC suction box 14 through the air vent, it can be discharged through the connecting pipe 19, L-shaped box 12, connector 21, corrugated hose 22, bend 25, connecting box 24, and vacuum pump 23, thus achieving continuous suction. Furthermore, the suction force at the bottom center of the PVC suction box 14 is greater than that on the bottom sides, so a negative pressure field distribution that dynamically decreases from the center to the edge can be created, effectively solving the problem of blind spots in the corner filling of traditional planar adsorption.

[0084] like Figure 8 As shown, the composite device also includes multiple pins 46. Multiple insertion holes 4 are equally spaced in a matrix on the tray 2. The pins 46 pass through the corresponding insertion holes 4. An arc-shaped protrusion 47 is integrally formed on each pin 46 located below the tray 2. A buffer groove 48 is formed on each pin 46. A fixing screw 49 is welded to the top of each pin 46. A fixing nut 50 is threaded onto the fixing screw 49, and a pressure plate 51 is fixedly mounted on the fixing nut 50. After placing the shirt fabric to be flattened and the down feathers laid inside the shirt fabric on the tray 2, the multiple pins 46 are inserted into the corresponding insertion holes 4, making the pins 46 tightly engage with the insertion holes 4. Then, by rotating the fixing nut 50, under the threaded transmission action with the fixing screw 49, the pressure plate 51 can be moved downwards, using the pressure plate 51 to press the edges and corners of the shirt fabric, thereby pressing and positioning the shirt fabric.

[0085] This invention proposes a method for using a down-filling composite device for a slim-fit thermal shirt based on PVC board, comprising the following steps:

[0086] S1. First, the inner lining fabric, down, and outer fabric used to make the down shirt are stacked on the tray 2, and the down is wrapped by the inner lining fabric and the outer fabric. Then, multiple pins 46 are inserted into the corresponding holes 4, so that the pins 46 are tightly engaged with the holes 4. After that, by rotating the fixing nut 50, the pressure plate 51 can be moved downward under the thread transmission action of the fixing screw 49. The pressure plate 51 is used to press the corners of the shirt fabric, so as to press and position the shirt fabric.

[0087] S2. By starting the stepper motor 16, the adjusting screw 17 is driven to rotate. At this time, under the thread transmission with the adjusting nut 18, the adjusting plate 11 can be driven to move longitudinally, thereby adjusting the height of the L-shaped box 12. Furthermore, the PVC suction box 14 can be adjusted to the specified height so that the PVC suction box 14 keeps in contact with the fabric on the upper layer.

[0088] S3. By starting the vacuum pump 23, suction can be generated, which can keep the PVC suction box 14 suction, and can adsorb and flatten the down in the shirt. After the gas is drawn into the PVC suction box 14 through the air hole, it can be discharged through the connecting pipe 19, L-shaped box 12, connector 21, corrugated hose 22, bend 25, connecting box 24 and vacuum pump 23, thus achieving continuous suction. In addition, the suction at the bottom center of the PVC suction box 14 is greater than that on the bottom sides, so a negative pressure field distribution that dynamically decreases from the center to the edge can be constructed, effectively solving the problem of blind spots in the corner filling of traditional planar adsorption.

[0089] S4. At the same time, the drive motor 41 is started to drive the active synchronous pulley 42 to rotate. At this time, under the transmission cooperation of the synchronous belt 44 and the two driven synchronous pulleys 43, the two transmission screws 40 can be driven to rotate. Under the thread transmission action with the corresponding threaded plate 6, the gantry frame 7 can be driven to move laterally. When the down in the shirt is attracted, leveled and pressed, the PVC attraction box 14 can be driven to move laterally. This can achieve the attraction and leveling of the entire down. When the PVC attraction box 14 moves laterally, the guide strip 15 can be used to pre-guide the shirt fabric to keep the PVC attraction box 14 moving smoothly.

[0090] S5. After the down feathers inside the shirt fabric are drawn and leveled, pull the insert rod 38 upwards to move it out of the slot 37. At this point, push the drag rod 32 to move it laterally. Under the sliding engagement of the connecting rod 33 and the collar 34, the transmission rod 35 can be driven to rotate upwards in an arc shape, which in turn drives the adjusting shaft 27 to rotate, causing the pressure roller 29 to rotate downwards for adjustment. When the pressure roller 29 moves to press the shirt fabric, the slot 37 on the other side can correspond to the position of the insert rod 38, and the insert rod 38 can be released. 8. The tension spring 39 under stress can drive the insertion rod 38 to move downward into the corresponding slot 37 to position the drag rod 32. Furthermore, it can limit the height of the pressure roller 29. At this time, the drive motor 41 is started to drive the gantry frame 7 to move laterally. One side can drive the pressure roller 29 to move laterally. At the same time, after the spiral heating wire 30 is energized, the pressure roller 29 can be heated. The pressure roller 29 in a high-temperature state can be used to heat press the down inside the shirt to shape the down.

[0091] However, as is well known to those skilled in the art, the working principles and wiring methods of the stepper motor 16, vacuum pump 23, spiral heating wire 30 and drive motor 41 are commonplace and belong to conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0092] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0093] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. In the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
