Description

Technical Field

[0001] This application relates to the field of garment processing technology, and more specifically, to a feeding mechanism and a collar-feeding machine. Background Technology

[0002] In related technologies, after completing the sewing operation, the lapel machine typically pushes the lapel directly into the feeding hopper, where it slides down to the collection position under its own weight. However, relying solely on gravity for feeding can easily cause the lapel to shift or fold during its descent, resulting in disordered stacking and hindering subsequent transfer and retrieval. These disordered stacks of lapels often require manual sorting before entering the next process, which not only increases additional labor time but also affects overall production efficiency. Utility Model Content

[0003] This application provides a feeding mechanism and a collaring machine to solve at least one of the above-mentioned technical problems.

[0004] The feeding mechanism of this application embodiment is used in a collar attaching machine, the collar attaching machine includes a feeding bin, and the feeding mechanism includes: A worktable, the worktable including an edge; A pressure plate assembly, the pressure plate assembly including a pressure plate configured to laterally move one end of the lapel out of the edge in a first direction after sewing is completed; A flip-plate assembly includes a flip-plate, one end of which is rotatably connected to the workbench, and the other end of which flips from below the edge along the first direction when the flip-plate rotates. The pressure plate is used by the lapel machine to move one end of the lapel laterally out of the edge along the first direction and place it on the flip-plate after the lapel machine has finished sewing, so that the flip-plate flips to press the lapel into the feed hopper.

[0005] The feeding mechanism proposed in this application uses a pressure plate to smoothly push the collar onto a flip plate, and then the flip plate rotates actively to press the collar into the feeding bin. This effectively prevents the collar from shifting or folding during recycling, which would cause disordered stacking. It eliminates the need for manual sorting before subsequent processes and improves production efficiency.

[0006] In some embodiments, the flip panel assembly further includes a first driving member for driving the flip panel to flip.

[0007] In this way, by setting a first drive component that is electrically connected to the control components, the automatic and precise control of the flipping action is realized, ensuring coordinated operation with the action of the pressure plate.

[0008] In some embodiments, the first driving member includes a rotating shaft, a gear, a rack, and a first cylinder. The flap is rotatably mounted on the worktable via the rotating shaft. The gear is mounted on the rotating shaft. The rack is slidably mounted on the worktable and meshes with the gear. The first cylinder is mounted on the worktable and has a driving end connected to the rack.

[0009] In this way, by cooperating with the gears, racks and pinions and the first cylinder, the linear motion of the cylinder is converted into the rotational motion of the flip plate, providing a stable and precise flipping method.

[0010] In some embodiments, the flap is slidably disposed on the worktable along a first direction, and after the flap is pushed out along the first direction, the flap flips to press the collar into the unloading hopper.

[0011] In this way, by allowing the flap to slide out along the first direction, it is easier for the flap to adapt to lapels of more lengths, thus improving the versatility of the unloading mechanism.

[0012] In some embodiments, the flap assembly further includes a second drive member for driving the flap to extend.

[0013] In this way, by setting a second drive component that is electrically connected to the control component, the automatic control of the flip-out action is realized, further improving the automation and coordination of the entire unloading process.

[0014] In some embodiments, the flap assembly further includes a linear slide rail and a slider, the linear slide rail being mounted on the worktable along the first direction, and the flap being slidably disposed on the slide rail via the slider.

[0015] In this way, the cooperation between the linear guide rail and the slider provides high-precision, low-friction guidance for the linear sliding of the flap, ensuring the smooth and stable movement process.

[0016] In some embodiments, the flip plate is provided with a first plane, and the first plane of the flip plate is provided with air holes. The feeding mechanism further includes an air source, which is connected to the air holes. When the flip plate flips, the air source blows air from the air holes.

[0017] Thus, by setting air holes on the flip plate and connecting them to an air source, air is blown when the flip plate flips, and the airflow is used to separate the lapel from the flip plate surface and allow it to slide smoothly into the unloading hopper, effectively preventing jamming or folding caused by static electricity or adhesion.

[0018] In some embodiments, the flap assembly further includes a flow regulator mounted on the flap and configured to control the airflow through the vent.

[0019] Thus, by installing an adjustable flow regulator on the air vent, it is easy to precisely control the airflow according to the material and weight of the lapel, optimize the blowing effect, and enhance applicability.

[0020] In some embodiments, the pressure plate assembly further includes a pressure plate drive mounted on the worktable, the pressure plate drive being used to drive the pressure plate to move one end of the lapel laterally out of the edge along a first direction and onto the flap after sewing is completed.

[0021] In this way, by setting up a pressure plate drive component, the mechanization and automation of the pressure plate's horizontal movement and collar placement are achieved, ensuring the accuracy of the movement force and position.

[0022] Another embodiment of the collaring machine of this application includes the feeding mechanism described in any of the above claims.

[0030] In related technologies, after completing the sewing operation, the lapel machine typically pushes the lapel directly into the feeding hopper, where it slides down to the collection position under its own weight. However, relying solely on gravity for feeding can easily cause the lapel to shift or fold during its descent, resulting in disordered stacking and hindering subsequent transfer and retrieval. These disordered stacks of lapels often require manual sorting before entering the next process, which not only increases additional labor time but also affects overall production efficiency.

[0031] Please see Figure 1 This application provides a lapel collar machine 1000, which includes a feeding mechanism 100 and a feeding bin 200. The feeding mechanism 100 includes a worktable 10, a pressure plate assembly 20, a flip plate assembly 30, and a control assembly. The worktable 10 includes an edge 11. The pressure plate assembly 20 includes a pressure plate 21, which is configured to move one end of the lapel collar laterally out of the edge 11 in a first direction after sewing is completed. The flip plate assembly 30 includes a flip plate 31, one end of which is rotatably connected to the worktable 10, and the other end of which flips over from below the edge 11 in the first direction when the flip plate 31 rotates. The pressure plate 21 is used by the lapel collar machine 1000 to move one end of the lapel collar laterally out of the edge 11 in the first direction and place it on the flip plate 31 after sewing is completed, so that the flip plate 31 flips over to press the lapel collar into the feeding bin 200.

[0032] The feeding mechanism 100 proposed in this application smoothly pushes the collar onto the flip plate 31 through the pressure plate 21 and accurately overlaps it. Then the flip plate 31 rotates actively to press the collar into the feeding bin 200, which effectively prevents the collar from shifting or folding during recycling, causing disordered stacking. This eliminates the necessary manual sorting step before subsequent processes and improves production efficiency.

[0033] For details, please refer to Figures 1 to 3In this embodiment, the feeding mechanism 100 further includes a control component. The pressure plate assembly 20 and the flip plate assembly 30 are both electrically connected to the control component. The control component is configured to control the pressure plate 21 to move one end of the lapel laterally out of edge 11 along a first direction and onto the flip plate 31 after sewing is completed. Then, it controls the flip plate 31 to flip and press the lapel into the feeding bin 200. The control component can be a programmable logic controller (PLC) or an industrial computer (IPC). The controller has a pre-stored precise action timing program. After the sewing machine completes the last stitch on the lapel and sends a completion signal, the controller first sends a command to the pressure plate drive 22. Driven by the pressure plate drive 22, the pressure plate 21 precisely presses down one end of the lapel and then moves smoothly along the first direction, dragging the lapel laterally from the workbench 10 out of its edge 11. The first direction is typically the length direction of the lapel. This process requires ensuring that the pressure plate 21 applies uniform force to the lapel, effectively overcoming the slight friction between the fabric and the work surface without causing collar deformation due to excessive tension. Once the pressure plate 21 has moved to the predetermined position, meaning the main body of the lapel has extended from the edge 11 of the workbench 10 and naturally rests on the top surface of the flip plate 31, which is initially in a vertical position, the controller immediately sends a flipping command to the first drive member 32 of the flip plate assembly 30. Driven by the first drive member 32, the flip plate 31, with its hinge point with the workbench 10 as its axis, rapidly flips downwards from a horizontal position (e.g., flipping 90 degrees to a horizontal or greater angle), smoothly "unfolding" and "throwing out" the lapel resting on it, pressing it into the unloading bin 200. The entire motion sequence—the horizontal movement and placement of the pressure plate 21, and the flipping of the flip plate 31—is seamlessly connected and completed in one go under the coordination of the controller. This automated operation not only completely avoids wrinkles caused by pulling and improper stacking during traditional manual material handling, but also eliminates pinch marks or positional deviations that may occur when a robotic arm grasps the material. The material unloading bin 200 can be designed as a flexible collection frame with a certain depth or a tiered rack. When the flip plate 31 "presses" the lapel into the bin, the lapel slides or folds down in a near-natural, flat state, greatly reducing the need for subsequent finishing. For example, this smooth unloading method is particularly important for high-end fabrics such as silk that are prone to permanent wrinkles. The surface materials of the pressure plate 21 and the flip plate 31 can be selected from engineering plastics with a moderate coefficient of friction or metal with a powder-coated surface to reduce scratching of the fabric.

[0034] In some embodiments, the pressure plate assembly 20 further includes a first sensor, which may be a photoelectric sensor or a position sensor. The first sensor is used to detect the position of the pressure plate 21. When the first sensor detects that the pressure plate 21 drags the collar horizontally from the table surface of the workbench 10 and moves it beyond its edge 11, it sends a flip signal to the control assembly. When the control assembly receives the flip signal, it controls the flip plate 31 to flip so as to press the collar into the unloading bin 200.

[0035] Please see Figure 2 and Figure 3 In some embodiments, the flip panel assembly 30 further includes a first drive member 32 for driving the flip panel 31 to flip.

[0036] Thus, by setting up a first drive component 32 that is electrically connected to the control component, the automatic and precise control of the flipping action of the flip plate 31 is realized, ensuring coordinated operation with the action of the pressure plate 21.

[0037] Specifically, in this embodiment, the first drive unit 32 is mounted on the workbench 10 and electrically connected to the control component. The control component is configured to drive the flip plate 31 to flip via the first drive unit 32. The control component (PLC) sends control pulse signals to the first drive unit 32 through a dedicated pulse output module or communication bus (such as EtherCAT) to precisely control the rotation angle and speed of the flip plate 31. For example, the control component's program can be set to rotate the flip plate 31 from a vertical 0-degree position to a 90-degree horizontal position or a 110-degree tilted position at a uniform speed within 0.5 seconds, hold it briefly after reaching the target position to ensure the collar completely slides down, and then rotate it back to the initial position in the opposite direction to prepare for the next action. This driving method has the advantages of high positioning accuracy, adjustable speed, fast response speed, low noise, and convenient maintenance.

[0038] Please see Figure 2 In some embodiments, the first driving member 32 includes a rotating shaft 321, a gear 322, a rack 323, and a first cylinder 324. The flap 31 is rotatably mounted on the worktable 10 via the rotating shaft 321. The gear 322 is mounted on the rotating shaft 321. The rack 323 is slidably mounted on the worktable 10 and meshes with the gear 322. The first cylinder 324 is mounted on the worktable 10 and has a driving end connected to the rack 323.

[0039] Thus, through the cooperation of gear 322, rack 323 and first cylinder 324, the linear motion of the cylinder is converted into the rotational motion of the flip plate 31, providing a stable and precise flipping method.

[0040] Specifically, in this embodiment, the rotating shaft 321 is typically mounted on the worktable 10 below the table surface or on the side frame via two bearings with mounting brackets, ensuring its flexible rotation. The gear 322 is preferably a spur gear with a small module, and is securely mounted on the rotating shaft 321 via a key connection or set screws. The rack 323 is arranged vertically parallel to the push rod direction of the first cylinder 324. The rack 323 is mounted within a set of linear guide pairs or simple grooves to ensure that it can only slide smoothly in a predetermined direction, avoiding jamming when meshing with the gear 322.

[0041] In this embodiment, the first cylinder 324 is preferably a double-acting cylinder. Its cylinder body is fixed to a suitable position on the worktable 10 via a hinge seat or flange. The first cylinder 324 includes a drive end, i.e., a piston rod. The end of the piston rod is connected to one end of the rack 323 via a spherical bearing. This floating connection can compensate for a small amount of installation alignment error. When the control component supplies air to the rod-side or rodless-side chamber of the first cylinder 324 via a solenoid valve, the piston rod extends or retracts, driving the rack 323 to perform linear motion. The gear 322 meshing with the rack 323 converts this linear motion into rotational motion in both directions, thereby driving the flip plate 31, which is coaxial with the gear 322, to complete the flipping action.

[0042] In this embodiment, the gear 322 and rack 323 can be made of surface-hardened 45 steel or wear-resistant engineering plastics such as MC nylon to ensure transmission accuracy and lifespan. To buffer the impact of the rack 323 at the end of its stroke, polyurethane buffer blocks can be added to both ends of its sliding path or the buffer device attached to the cylinder itself can be adjusted.

[0043] In some embodiments, a worm gear mechanism can be used instead of gears 322 and racks 323. The rotation of the motor directly drives the worm, which in turn drives the worm wheel connected to the rotating shaft 321 of the flap 31 to achieve the flipping and self-locking of the flap 31. However, the efficiency is relatively low.

[0044] In some embodiments, the first drive element 32 may also be a rotary cylinder. The cylinder body of the rotary cylinder is fixed on the worktable 10, and its output shaft is directly connected to the rotating shaft 321 of the flip plate 31. The control component controls the on / off and direction of compressed air through a solenoid valve, thereby driving the rotary cylinder to perform a fixed-angle swing (usually 90 degrees or 180 degrees). Although the cost of a rotary cylinder is relatively low, its movement speed and intermediate position are not easy to control precisely, and it has high requirements for the quality of the air source 40, which may result in some impact. Regardless of whether a motor or a cylinder is used, robust bearing seats need to be installed at both ends of the rotating shaft 321 of the flip plate 31 to ensure smooth rotation. In addition, an origin sensor or angle encoder can be installed on the rotating shaft 321 to provide feedback on the initial position of the flip plate 31, realize closed-loop control, and further improve the reliability and repeatability of the system. This automated flipping control ensures strict synchronization with the movement of the pressure plate 21, avoiding the rhythm inconsistency problem that may be caused by manual intervention.

[0045] In some embodiments, the first drive unit 32 may also be a servo motor or a stepper motor. The motor is fixed to the bottom or side bracket of the worktable 10 by a mounting bracket, and its output shaft is directly connected to the rotating shaft 321 behind the flip plate 31 by a coupling or by a set of reduction gears 322.

[0046] In some embodiments, the cylinder body of the first cylinder 324 may be rotatably mounted on the worktable 10, and the drive end of the first cylinder 324 may be hinged to the middle or top of the flip plate 31. In this way, the flip plate 31 can be flipped directly by the extension and retraction of the first cylinder 324.

[0047] Please see Figure 1 In some embodiments, the flap 31 is slidably disposed on the worktable 10 along the first direction. After the flap 31 is pushed out along the first direction, the flap 31 flips over to press the collar into the unloading bin 200.

[0048] Thus, by allowing the flap 31 to slide out along the first direction, the flap 31 can be adapted to lapels of more lengths, thereby improving the versatility of the unloading mechanism 100.

[0049] Specifically, in this embodiment, the control component is configured to control the flap 31 to extend along a first direction, and then control the flap 31 to flip and press the lapel into the unloading bin 200. The flap 31 is slidably set along the first direction. When different lengths of lapels need to be processed, the control component can, according to a preset program or externally input specifications (e.g., selecting the lapel type via a touch screen), first control the flap 31 to slide, pushing the entire flap assembly 30 outward along the first direction (i.e., away from the center of the workbench 10) to a predetermined extended position. Then, the pressure plate 21 performs the action of lateral movement and placing the lapel. For example, for longer lapels, the flap 31 needs to extend further to unfold and throw the lapel to a farther position to prevent the lapel from slipping out of the unloading bin 200. Subsequently, the flap 31 can retract while or after performing the flipping action, or remain extended to complete the unloading and then retract. This push-flip-retract composite motion greatly enhances the adaptability of the unloading mechanism 100 to different product sizes. For example, when switching between producing men's suit lapels and women's short jacket lapels on the same production line, no hardware adjustments are required. The material feeding position can be automatically adjusted simply by calling different parameters in the program, effectively improving the equipment's flexible production capabilities.

[0050] Please see Figure 2 and Figure 3 In some embodiments, the flap assembly 30 further includes a second drive member 33 for driving the flap 31 to extend.

[0051] Thus, by setting a second drive component 33 that is electrically connected to the control component, the automatic control of the flap 31's push-out action is realized, further improving the automation and coordination of the entire unloading process.

[0052] Specifically, in this embodiment, the second drive unit 33 is mounted on the worktable 10 and electrically connected to the control component, which is configured to drive the flap 31 outward via the second drive unit 33. The second drive unit 33 may be a double-acting miniature cylinder and is driven by compressed air controlled by a solenoid valve. Cylinders are low-cost and fast-acting, but their stroke is usually fixed, and position adjustment needs to be achieved through mechanical stops or external sensors.

[0053] In some embodiments, the second drive element 33 may be a miniature electric linear actuator. The motor (typically a DC motor) of this actuator is electrically connected to the control assembly and integrates a screw-nut mechanism to convert the motor's rotational motion into the linear extension and retraction of the actuator. The actuator body is fixed to a stationary portion of the worktable 10 by a bracket, while its end is connected to the slider 35 or base supporting the flap assembly 30. The control assembly supplies power to the electric linear actuator and controls its polarity via a relay or DC motor driver, thereby precisely controlling the extension and retraction stroke of the actuator. The advantages of this approach are precise control, low noise, and ease of multi-point position control.

[0054] In some embodiments, to ensure the accuracy of the sliding position, a displacement sensor (such as a magnetostrictive ruler or a wire encoder) can be installed next to the second drive component 33, or multiple position detection sensors (such as proximity switches) can be set to provide real-time feedback on the position of the flap 31 to the control component, thereby achieving closed-loop control. In this way, regardless of whether electric or pneumatic drive is used, it can be ensured that the flap 31 can accurately stop at the program-set position each time, thus perfectly coordinating with the placement action of the pressure plate 21, ensuring that the collar can always be accurately placed within the effective area of ​​the flap 31.

[0055] Please see Figure 2 In some embodiments, the flip plate assembly 30 further includes a linear slide rail 34 and a slider 35. The linear slide rail 34 is mounted on the worktable 10 along a first direction, and the flip plate 31 is slidably disposed on the slide rail by the slider 35.

[0056] Thus, the cooperation between the linear guide rail 34 and the slider 35 provides high-precision, low-friction guidance for the linear sliding of the flip plate 31, ensuring the smooth and stable movement process.

[0057] Specifically, in some embodiments, the linear guide rail 34 is crucial for ensuring the smoothness and accuracy of the linear movement of the flip plate 31. Typically, the linear guide rail 34 can be selected from a set of miniature or small ball linear guide pairs with appropriate precision levels. The linear guide rail 34 is installed on the surface of the worktable 10 or on the support frame below the worktable 10 after being strictly leveled in the first direction using screws or bolts, to ensure the flatness and straightness of its mounting surface.

[0058] In some embodiments, the slider 35, which mates with the linear guide rail 34, is fixed to the first drive member 32 by screws. The slider 35 contains ball bearings, enabling high-precision, low-friction rolling on the guide rail. For dust prevention and extended lifespan, slider 35 with sealed end caps and scrapers can be selected.

[0059] In some embodiments, a combination of linear sliding bearings (linear bearings) and hard chrome-plated optical shafts (round shafts) can also be used. The linear bearings are typically mounted in bearing housings within the base of the flip plate 31, and the optical shaft is fixed at both ends to the support of the worktable 10. This solution is less expensive, but it is inferior to linear guides in terms of torque bearing capacity and accuracy retention.

[0060] Furthermore, it is important to note that regardless of the chosen method, a mechanical limit block (such as an adjustable screw) must be installed at the end of the sliding stroke as a safety redundancy in addition to the electrical limit, preventing the slider 35 from overtraveling and falling off. A precise guiding mechanism ensures that the flap 31 does not wobble or jam during extension and retraction, providing a stable and reliable foundation for subsequent flipping actions.

[0061] Please see Figure 2 and Figure 3 In some embodiments, the flap 31 is provided with a first plane 311, and the first plane 311 of the flap 31 is provided with an air hole 312. The feeding mechanism 100 also includes an air source 40, which is connected to the air hole 312 and electrically connected to the control component. The control component is configured to control the air source 40 to blow air from the air hole 312 when the flap 31 is flipped.

[0062] Thus, by setting air holes 312 on the flap 31 and connecting them to an air source 40, air is blown when the flap 31 flips, and the airflow is used to separate the lapel from the surface of the flap 31 and allow it to slide smoothly into the unloading bin 200, effectively preventing jamming or folding caused by static electricity or adhesion.

[0063] Specifically, in this embodiment, the air source 40 is electrically connected to the control component, which is configured to control the air source 40 to blow air from the air holes 312 when the flap 31 is flipped. The first plane 311 is typically the top surface of the flap 31, and the body of the flap 31 is preferably hollow or has internal airflow channels. The top surface may have a plurality of small-diameter air holes 312 evenly distributed, and these air holes 312 are connected to the internal cavity of the flap 31.

[0064] In this embodiment, the air source 40 can be a small, silent air compressor or a centralized air circuit in a factory. It is connected to the rotary joint at the pivot 321 of the flap 31 via a hose (to ensure that the air pipe does not get tangled when flipping), and then connected to the internal cavity of the flap 31 via the rotary joint.

[0065] In this embodiment, the control component controls the airflow through a normally closed solenoid valve. The coil of the solenoid valve is connected to the output point of the control component. The control logic is as follows: simultaneously with or shortly after the flip plate 31 begins its flipping action (e.g., when the flipping angle reaches 30 degrees), the control component triggers the solenoid valve to open, and compressed air rapidly fills the inner cavity of the flip plate 31 and is simultaneously blown out from all the air holes 312. This airflow forms an air cushion between the lapel and the surface of the flip plate 31, effectively overcoming the electrostatic adsorption effect caused by the smooth surface of the fabric, or the adhesion that may occur due to slight dampness of the fabric. This allows the lapel to slide more smoothly and gracefully from the surface of the flip plate 31 to the discharge bin 200 under its own weight and the assistance of the airflow, avoiding folding, curling, or jamming caused by local adhesion during the flipping process.

[0066] In some embodiments, a filter, pressure reducing valve and oil mist lubricator (triple unit) may be installed in the pipeline of the air source 40 to ensure that the blown air is clean, dry and has stable pressure (e.g., adjustable to 0.2-0.5 MPa) and to avoid oil contamination of the collar.

[0067] Please see Figures 1 to 3 In some embodiments, the flap assembly 30 further includes a flow regulator 36 mounted on the flap 31 and configured to control the airflow of the vent 312.

[0068] Thus, by installing an adjustable flow regulator 36 on the air vent 312, it is easy to precisely control the air flow according to the material and weight of the lapel, optimize the blowing effect, and enhance applicability.

[0069] Specifically, in this embodiment, to optimize airflow and adapt to lapels of different materials and weights, an adjustable flow regulator 36 can be installed at the outlet of each air hole 312 or a group of key air holes 312. This flow regulator 36 is typically a knob-type structure made of brass or plastic, containing a conical needle valve. By rotating the housing of the flow regulator 36, the gap between the needle valve and the valve seat can be changed, thereby precisely adjusting the airflow through the air hole 312. For example, for a light and soft silk lapel, a gentle and evenly distributed airflow is needed to avoid strong airflow disrupting the fabric's shape. In this case, the opening of each flow regulator 36 can be reduced to make the airflow more gentle. For a heavier or stiffer wool lapel, the opening of the flow regulator 36 can be appropriately increased to provide stronger blowing force to ensure effective separation. The flow regulator 36 can be installed by directly screwing it into the pre-drilled threaded hole on the upper surface of the flap 31 using a threaded connection, facilitating installation and replacement.

[0070] In some embodiments, flow regulators 36 with different structures can also be used. For example, a fan-shaped flow regulator 36 can make the airflow blow out in a wide and flat shape, covering a large area; while a straight-beam flow regulator 36 concentrates the airflow and has a strong impact. Operators can make targeted adjustments and optimizations according to the actual fabric characteristics in production, thereby obtaining the best material feeding effect. This adjustable design greatly enhances the adaptability of the feeding mechanism 100 to diverse production needs, enabling a single mechanical structure to cope with multiple process requirements.

[0071] Please see Figure 2 and Figure 3 In some embodiments, the pressure plate assembly 20 further includes a pressure plate drive 22, which is mounted on the worktable 10. The pressure plate drive 22 is used to drive the pressure plate 21 to move one end of the lapel laterally out of the edge 11 along the first direction and onto the flap 31 after sewing is completed.

[0072] Thus, by setting up the pressure plate drive component 22, the mechanization and automation of the movement of the pressure plate 21 moving laterally and the placement of the lapel are realized, ensuring the accuracy of the force and position of the movement.

[0073] Specifically, in this embodiment, the pressure plate drive 22 is typically a three-dimensional movement module used to control the lifting and translation of the pressure plate 21. The control component precisely controls the moving distance, speed, and acceleration of the pressure plate 21 through the three-dimensional movement module. Its working cycle is as follows: After receiving the sewing completion signal, the pressure plate 21 first presses or clamps the designated part of the lapel (the bottom surface of the pressure plate 21 may be attached with a flexible material such as a silicone strip to prevent damage to the fabric), then drags the lapel horizontally out of the edge 11 of the worktable 10 at a steady speed along the first direction. After reaching the designated point above the flip plate 31, the pressure plate 21 releases and lifts, and finally quickly returns to the initial position to wait for the next cycle. The entire motion trajectory is smooth, precise, and adjustable.

[0074] In this embodiment, the three-dimensional movement module can be implemented by a combination of cylinders, such as two cylinders that move horizontally perpendicularly to each other and a cylinder that moves vertically, controlled sequentially by two solenoid valves.

[0075] In this embodiment, the pressure plate 21 itself can be elongated, with a length sufficient to cover the width of a common collar. To ensure uniform pressure, a floating joint can be added between the pressure plate drive 22 and the pressure plate 21, or a pressure plate 21 bracket with a self-balancing structure can be used. This mechanized action of the pressure plate 21 replaces manual pulling, ensuring consistency in the force and position of each feeding, fundamentally avoiding product quality fluctuations caused by differences in human operation.
