Description

Technical Field

[0001] This application relates to the field of suit production equipment, and in particular to a buttonhole machine and production process for suit production. Background Technology

[0002] A suit refers to a Western-style jacket or suit, and is the first choice for men's attire in companies and enterprises, as well as for formal occasions. The production process of a suit includes cutting, lining, splitting, attaching lining, gathering darts, joining armhole seams, pressing seams, finishing the front panel, opening the large pockets, opening the middle pockets, adding chest lining, making the facing lining, opening the inner pockets, attaching the placket, making the back, making the collar, attaching the collar, making the sleeves, attaching the cuffs, buttoning the buttons, and pressing.

[0003] Cufflinks and placket buttons are essential components of a suit. A buttonhole machine is required when processing buttonholes on a suit. The buttonhole machine is a very important piece of equipment in garment machinery, primarily used for processing buttonholes in various garments. Currently, when processing buttonholes on suits, to facilitate processing multiple buttonholes on the garment pieces, a feeding mechanism is typically used to feed the garment pieces to the buttonhole machine. The worker fixes the garment pieces on the feeding mechanism on the worktable, and the feeding mechanism drives the garment pieces to move periodically under the buttonhole machine, which processes multiple buttonholes on the garment pieces. After the buttonholes on the garment pieces are processed, the worker removes the garment pieces from the feeding mechanism and installs new garment pieces to be processed.

[0004] Regarding the aforementioned technologies, after each garment piece is processed, it is necessary to manually remove the processed garment piece and install a new garment piece to be processed. During this time, the buttonhole machine needs to be stopped and wait, resulting in long downtime and low production efficiency. Summary of the Invention

[0005] To improve production efficiency, this application provides a buttonhole machine and production process for suit production.

[0006] The technical solution provided in this application for a buttonhole machine and manufacturing process for suit production adopts the following:

[0007] On one hand, this application provides a buttonhole machine for suit production, including a buttonhole machine body and a processing table. The processing table is provided with a material box for placing garment pieces, and a material outlet is opened below the material box. A material picking mechanism is provided on the processing table and below the material box. The material picking mechanism is used to pick up garment pieces one by one from the material box. A first slide rail and a second slide rail with the same structure are arranged parallel to each other on the processing table. The first slide rail is located directly below the buttonhole machine body, and the second slide rail is close to the material box. A placement plate is slidably arranged on both the first slide rail and the second slide rail. A fixing mechanism for fixing garment pieces is provided on the placement plate. A first moving mechanism for driving the placement plate to move along the first slide rail or the second slide rail is provided on the placement plate. A second moving mechanism for driving the placement plate to move between the first slide rail and the second slide rail is also provided on the processing table. A conveyor belt is provided between the material picking mechanism and the placement plate on the second slide rail. The conveyor belt transports the garment pieces picked up by the material picking mechanism to the placement plate.

[0008] By adopting the above technical solution, multiple garment pieces are stacked and placed in a material box. A material handling mechanism removes the garment pieces one by one from the material box through the discharge port. A conveyor belt transports the removed garment pieces to a placement plate. A second moving mechanism drives the placement plate to move from the second slide rail to the first slide rail. The first moving mechanism drives the placement plate to move along the first slide rail. The garment pieces on the placement plate pass under the buttonhole machine and are processed by the buttonhole machine. After processing, the placement plate is moved to the second slide rail by the second moving mechanism, and the garment pieces are unloaded from the placement plate. Since placement plates are installed on both the first and second slide rails, the two placement plates circulate between the first and second slide rails. Thus, after the garment pieces on one placement plate are processed, the other placement plate moves to the bottom of the buttonhole machine for processing. This allows the buttonhole machine to work continuously without stopping, reduces the downtime of the buttonhole machine during loading and unloading, and improves processing efficiency.

[0009] Optionally, the material handling mechanism includes a lifting cylinder, a material handling plate, and material handling columns. The lifting cylinder is located below the processing table, and the piston rod of the lifting cylinder extends vertically upward. Multiple material handling plates are spaced apart at the end of the piston rod of the lifting cylinder. The material handling plates are vertically aligned with the discharge port of the material box. Multiple material handling columns are vertically arranged on each of the multiple material handling plates. A fabric bonding layer is provided at the top of each material handling column. A through hole for the multiple material handling plates to enter and exit is provided on the processing table and located below the material box. A panel is provided on the processing table, and a material handling hole is provided on the panel that is aligned with the multiple material handling columns. The conveyor belt is arranged on the panel and is aligned with the gap between two adjacent material handling plates.

[0010] By adopting the above technical solution, the lifting cylinder drives the picking plate to move upward, and the picking column extends towards the material box after passing through the picking hole. The fabric adhesive layer at the top of the picking column adheres to a piece of clothing at the bottom of the material box, and drives the piston rod of the lifting cylinder to retract, pulling out a piece of clothing from the bottom of the material box. The piston rod of the lifting cylinder continues to retract, and the picking column moves to below the panel. The piece of clothing is intercepted on the panel and transported to the placement plate by the conveyor belt, thereby achieving the effect of facilitating the sequential removal of pieces of clothing from the material box.

[0011] Optionally, the fixing mechanism includes a pressure plate and a drive motor. Pressure plates are rotatably mounted on both ends of the placement plate, and the drive motor is mounted on the placement plate and connected to the pressure plates.

[0012] By adopting the above technical solution, the drive motor is started, and the drive motor drives the pressure plate to rotate. When the garment piece is conveyed to the placement plate, the pressure plate rotates away from the placement plate. After the garment piece is placed on the placement plate, the drive pressure plate rotates toward the placement plate to press the garment piece firmly onto the placement plate. This ensures that the garment piece will not shift when the buttonhole machine processes the garment piece, thus ensuring the accuracy of the garment piece position during buttonhole processing.

[0013] Optionally, the processing table is also equipped with a flattening assembly for spreading the garment pieces. The flattening assembly includes a bracket, a servo motor, left and right rotary screws, and rollers. The bracket is L-shaped, with one end connected to the processing table and the other end extending horizontally above the second slide rail. The horizontal section of the bracket has a receiving groove. The left and right rotary screws are rotatably mounted on the bracket and located in the receiving groove. The servo motor is mounted on the bracket, and the output shaft of the servo motor is coaxially and fixedly connected to the left and right rotary screws. Two connecting rods are slidably mounted on the bracket and located in the receiving groove. The two connecting rods are threaded onto the two ends of the left and right rotary screws, and the rollers are rotatably mounted at the ends of both connecting rods.

[0014] By adopting the above technical solution, the servo motor is started, and the servo motor drives the left and right screws to rotate, thereby driving the two connecting rods to move closer or further apart. After the garment piece moves to the placement plate, the two connecting rods are driven to move further apart, and the rollers on the two connecting rods flatten and spread the garment piece on the placement plate, so that the garment piece laid on the placement plate remains flat and is easy to process.

[0015] Optionally, the bracket includes a fixed part and a telescopic part, the telescopic part is slidably disposed in the fixed part, and a lifting cylinder is disposed in the fixed part, the piston rod of the lifting cylinder extends vertically upward and is connected to the telescopic part.

[0016] By adopting the above technical solution, the lifting cylinder is used to adjust the distance between the roller and the placement plate. When the garment piece moves onto the placement plate, the driving roller moves away from the placement plate; when the garment piece is laid flat, the driving roller moves toward the placement plate and presses the garment piece against the placement plate; thus facilitating the movement of the garment piece onto the placement plate and making the garment piece spread out more evenly.

[0017] Optionally, the first moving mechanism includes a slider and a powered caster. The cross-sectional shape of the first slide rail and the second slide rail is T-shaped. The slider is disposed below the placement plate and is adapted to the first slide rail. The powered caster is disposed at the bottom of the slider.

[0018] By adopting the above technical solution, the power caster is a self-powered wheel. Activating the power caster drives the slider to move within the first or second slide rail, thereby facilitating the movement of the placement plate on the first and second slide rails.

[0019] Optionally, the second moving mechanism includes a baffle, a guide block, and a telescopic cylinder. The baffle is provided at both ends of the processing table. A guide groove is formed on the baffle along its length. Guide blocks that match the guide grooves are provided at both ends of the placement plate. Both the guide grooves and guide blocks have a T-shaped cross-section. The telescopic cylinder is located at one end of the baffle, and its piston rod extends into the baffle. The telescopic cylinders at both ends of the processing table are staggered. A through groove is provided on both the first and second slide rails for the slider to enter and exit. A connecting groove is formed on the baffle opposite to the guide blocks on the two placement plates, and the connecting groove is connected to the guide groove. When the guide block is located within the connecting groove, the slider is directly opposite the through groove.

[0020] By adopting the above technical solution, the placement plate moves on the first slide rail. When the guide block at one end of the placement plate moves into the guide groove through the connecting groove, the slider is aligned with the through groove. At this time, the telescopic cylinder is activated, and the piston rod of the telescopic cylinder pushes the guide block to move along the guide groove. The slider moves out of the first slide rail through the through groove on the first slide rail and moves to the second slide rail through the through groove on the second slide rail. At this time, the connecting groove is aligned with the guide block, and the placement plate can move along the second slide rail. The principle is the same when the placement plate moves from the second slide rail to the first slide rail. This facilitates driving the placement plate to move between the first and second slide rails.

[0021] Optionally, a material collection hole is provided on one side of the processing table and located in the material box, and a material collection box is placed in the material collection hole. A mounting frame is provided on the placement table, and a cleaning roller is rotatably mounted on the mounting frame. The cleaning roller is located on one side of the material collection box and directly above the first slide rail.

[0022] By adopting the above technical solution, the cleaning roller is driven to rotate, and the cleaning roller sweeps the garment pieces on the placement plate toward the collection hole, and the garment pieces fall into the collection box, thereby achieving the effect of making it easier to remove the garment pieces from the placement plate.

[0023] On the other hand, this application provides a suit manufacturing process, including the following steps:

[0024] S1: Cut and lay out the fabric; S2: Lay out and attach the interfacing to the fabric, and sew the front piece, large pocket, and handkerchief pocket; S3: Sew the chest lining and double chest lining; S4: Sew the back of the suit, the hem seam, and the shoulder seam; S5: Sew the suit collar and sleeves; S6: Process the buttonholes of the suit using the buttonhole machine, and simultaneously perform the buttonhole attaching operation.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. Multiple garment pieces are stacked and placed in a material bin. A material handling mechanism removes the garment pieces one by one from the bin through the discharge port. A conveyor belt transports the removed garment pieces to a placement plate. A second moving mechanism drives the placement plate from the second slide rail to the first slide rail. The first moving mechanism drives the placement plate to move along the first slide rail. The garment pieces on the placement plate pass under the buttonhole machine and are processed by the buttonhole machine. After processing, the placement plate is moved to the second slide rail by the second moving mechanism, and the garment pieces are unloaded from the placement plate. Since placement plates are installed on both the first and second slide rails, the two placement plates circulate between the first and second slide rails. Thus, after the garment pieces on one placement plate are processed, the other placement plate moves under the buttonhole machine to process the garment pieces. This allows the buttonhole machine to work continuously without stopping, reducing the downtime of the buttonhole machine during loading and unloading and improving processing efficiency.

[0027] 2. The lifting cylinder drives the picking plate to move upward. After the picking column passes through the picking hole, it extends towards the material box. The fabric adhesive layer at the top of the picking column adheres to a piece of clothing at the bottom of the material box. The piston rod of the lifting cylinder is driven to retract, pulling out a piece of clothing from the bottom of the material box. The piston rod of the lifting cylinder continues to retract, and the picking column moves to below the panel. The piece of clothing is intercepted on the panel and transported to the placement plate by the conveyor belt, thereby achieving the effect of facilitating the removal of pieces of clothing one by one from the material box.

[0028] 3. The placement plate moves on the first slide rail. When the guide block at one end of the placement plate moves into the guide groove through the connecting groove, the slider is aligned with the through groove. At this time, the telescopic cylinder is activated, and the piston rod of the telescopic cylinder pushes the guide block to move along the guide groove. The slider moves out of the first slide rail through the through groove on the first slide rail and moves onto the second slide rail through the through groove on the second slide rail. At this time, the connecting groove is aligned with the guide block, and the placement plate can move along the second slide rail. The principle is the same when the placement plate moves from the second slide rail to the first slide rail. This facilitates driving the placement plate to move between the first and second slide rails. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0036] This application discloses a buttonhole machine for suit production, referring to... Figure 1 and Figure 2A buttonhole machine for suit production includes a buttonhole machine body 1 and a processing table 2. The processing table 2 is a rectangular table, and the processing area of ​​the buttonhole machine is located on one side of the processing table 2. A material box 3 for placing garment pieces is installed on the processing table 2. The material box 3 is a hollow rectangular box with a gap between the material box 3 and the processing table 2. A discharge port 31 is opened at the bottom of the material box 3. A material picking mechanism 4 is installed on the processing table 2 and below the material box 3. The material picking mechanism 4 is used to pick up garment pieces one by one from the material box 3 through the discharge port 31. A first slide rail 11 and a second slide rail 12 with identical structures are installed parallel to each other on the processing table 2. The length direction of the first slide rail 11 and the second slide rail 12 is along the length direction of the processing table 2. The first slide rail 11 is located directly below the buttonhole machine body 1, and the second slide rail 12 is located on the side of the first slide rail 11 closer to the material box 3. A placement plate 5 is slidably installed on both the first slide rail 11 and the second slide rail 12. The placement plate 5 is a rectangular plate, and its length direction is along the length direction of the first slide rail 11. A fixing mechanism 51 for fixing garment pieces is installed on the placement plate 5. A first moving mechanism 6 for driving the placement plate 5 to move along the first slide rail 11 or the second slide rail 12 is also installed on the placement plate 5. A second moving mechanism 7 for driving the placement plate 5 to move between the first slide rail 11 and the second slide rail 12 is installed on the processing table 2. A conveyor belt 13 is installed between the material picking mechanism 4 and the second slide rail 12. The conveyor belt 13 transports the garment pieces taken out of the material box 3 by the material picking mechanism 4 to the placement plate 5.

[0037] Multiple garment pieces are placed in the material bin 3. The material handling mechanism 4 removes the garment pieces one by one from the material bin 3. The removed garment pieces are conveyed by the conveyor belt 13 to the placement plate 5 on the second slide rail 12. The fixing mechanism 51 fixes the garment pieces to the placement plate 5. The second moving mechanism 7 drives the placement plate 5 to move onto the first slide rail 11, and the first moving mechanism 6 drives the placement plate 5 to move along the first slide rail 11, so that the garment pieces on the placement plate 5 pass under the buttonhole machine for processing. After processing, the garment pieces are removed from the placement plate 5, and the placement plate 5 is driven to move again onto the second slide rail 12, and then driven to one side of the material bin 3 to receive the garment pieces. Since placement plates 5 are installed on both the first slide rail 11 and the second slide rail 12, the two placement plates 5 move cyclically on the first slide rail 11 and the second slide rail 12, continuously conveying garment pieces to the buttonhole machine for processing, thereby reducing the downtime of the buttonhole machine and improving processing efficiency.

[0038] Reference Figure 2The size of the discharge port 31 below the material box 3 is smaller than the size of the bottom surface of the material box 3, so that when the garment piece is placed in the material box 3, all four sides of the garment piece are in contact with the bottom surface of the material box 3. The frictional resistance around the garment piece is greater than the weight of the garment piece at the discharge port 31, so that the garment piece will not fall off the discharge port 31. The material picking mechanism 4 includes a lifting cylinder 41, a picking plate 42, and a picking column 43. The lifting cylinder 41 is fixedly installed below the processing table 2 by the stiffening plate of the processing table 2. The lifting cylinder 41 and the discharge port 31 of the material box 3 are directly opposite each other in the vertical direction. The piston rod of the lifting cylinder 41 extends vertically upwards. Multiple material-picking plates 42 are spaced apart at the end of the piston rod, with gaps between adjacent plates. The overall dimensions of the multiple material-picking plates 42 are the same as the outlet 31 of the material box 3. Multiple material-picking columns 43 are vertically arranged on the upper surface of each material-picking plate 42, with a fabric adhesive layer at the top of each column 43. The fabric adhesive layer is a bondable fabric layer, meaning it can bond with various fabrics, such as the nylon hook and loop in Velcro. The fabric adhesive layer can bond with garment pieces. A through-hole 14 is provided on the processing table 2, located below the material box 3, for the multiple material-picking plates 42 to enter and exit. The material-picking plates 42 move between the upper and lower sides of the processing table 2 through the through-hole 14. A panel 44 is horizontally mounted on the processing table 2, below the material bin 3. The panel 44 is a rectangular plate with material picking holes 45 that are directly opposite to multiple material picking columns 43. One side of the panel 44 extends towards the placement plate 5. Multiple conveyor belts 13 are mounted on the panel 44, and the gaps between the conveyor belts 13 and the adjacent material picking plates 42 are directly opposite each other. The upper surface of the conveyor belts 13 is flush with the upper surface of the panel 44. A polytetrafluoroethylene (PTFE) layer is also coated on the panel 44. PTFE has a very low coefficient of friction, resulting in low frictional resistance when the garment pieces move on the panel 44.

[0039] Activate the lifting cylinder 41, and the piston rod of the lifting cylinder 41 extends or retracts, thereby driving the material picking plate 42 to move upward. The material picking column 43 extends towards the material box 3 after passing through the material picking hole 45. Multiple material picking columns 43 enter the material box 3 through the material outlet 31. The fabric adhesive layer at the top of the material picking column 43 adheres to a piece of clothing at the bottom of the material box 3. Drive the piston rod of the lifting cylinder 41 to retract, and the multiple material picking columns 43 move a piece of clothing at the bottom of the material box 3 and pull the piece of clothing out of the material box 3. The piston rod of the lifting cylinder 41 continues to retract, and the material picking column 43 moves along the material picking hole 45 to below the panel 44. The piece of clothing is intercepted on the panel 44 and transported to the placement plate 5 by the conveyor belt 13, thereby achieving the effect of facilitating the sequential removal of pieces of clothing from the material box 3.

[0040] Reference Figure 3 and Figure 4The fixing mechanism 51 includes a pressure plate 511 and a drive motor 512. Pressure plates 511 are rotatably mounted on both ends of the placement plate 5 via hinged seats. The pressure plates 511 are rectangular plates. Drive motors 512 are mounted on both ends of the mounting plate, and the output shaft of the drive motor 512 is fixedly connected to the pressure plates 511. The output shaft of the drive motor 512 and the rotation axis of the pressure plates 511 are on the same straight line. During the process of conveying the garment piece toward the placement plate 5, the drive motor 512 drives the pressure plate 511 to move away from the upper surface of the placement plate 5. After the garment piece is positioned on the placement plate 5, the drive motor 512 drives the pressure plate 511 to rotate toward the surface of the placement plate 5 and press the garment piece firmly onto the placement plate 5.

[0041] Reference Figure 3 The processing table 2 is also equipped with a flattening assembly 8 for spreading the garment pieces flat. The flattening assembly 8 includes a support 81, a servo motor 82, a left and right rotary screw 83, and a roller 84. The support 81 is an L-shaped rod, which is installed on the side of the processing table 2 near the material box 3. One end of the support 81 is connected to the side of the processing table 2, and the other end extends horizontally above the second slide rail 12. A receiving groove 85 is provided on the horizontal section of the support 81 facing the processing table 2. The left and right rotary screw 83 is rotatably mounted on the support 81 and located in the receiving groove 85. The servo motor 82 is fixedly mounted on the bracket 81, and the output shaft of the servo motor 82 is fixedly connected to the left and right screws 83 on the same axis. Two connecting rods 86 are slidably mounted on the bracket 81 and located in the receiving groove 85. One end of each connecting rod 86 is located in the receiving groove 85, and the other end extends vertically downward. The two connecting rods 86 are respectively threaded onto the two ends of the left and right screws 83. A roller shaft 84 is rotatably mounted at the end of each of the two connecting rods 86. The length direction of the roller shaft 84 is perpendicular to the length direction of the placement plate 5.

[0042] The servo motor 82 is started, which drives the left and right lead screws 83 to rotate, thereby driving the two connecting rods 86 to move closer or further apart. When there are no garment pieces on the placement plate 5, the two connecting rods 86 are driven to move closer together. After the garment pieces are conveyed to the placement plate 5 by the conveyor belt 13, the two connecting rods 86 are driven to move further apart. The rollers 84 on the two connecting rods 86 flatten and spread the garment pieces on the placement plate 5, so that the garment pieces are laid flat on the placement plate 5, thereby keeping the garment pieces laid on the placement plate 5 in a flat state, which is convenient for subsequent processing of the garment pieces.

[0043] Reference Figure 3The support frame 81 includes a fixed part 811 and a telescopic part 812. The fixed part 811 is the lower part of the vertical section of the support frame 81 and has an opening at the top. The telescopic part 812 is slidably installed inside the fixed part 811. A lifting cylinder 813 is installed inside the fixed part 811. The piston rod of the lifting cylinder 813 extends vertically upward, and the end of the piston rod is fixedly connected to the telescopic part 812. During the process of conveying the garment piece toward the placement plate 5, the lifting cylinder 813 drives the roller shaft 84 to move upward, so that the garment piece can move smoothly onto the placement plate 5. Then, the lifting cylinder 813 drives the roller shaft 84 to move toward the placement plate 5 and come into contact with the garment piece, flattening the garment piece. This facilitates the movement of the garment piece onto the placement plate 5 and also makes the garment piece spread out more evenly.

[0044] Reference Figure 1 and Figure 4 The first moving mechanism 6 includes a slider 61 and a power caster 62. The first slide rail 11 and the second slide rail 12 both have a T-shaped cross-section. Two sliders 61 are fixedly connected to the bottom of the placement plate 5. The sliders 61 are adapted to the first slide rail 11 and the second slide rail 12. The power caster 62 is rotatably mounted on the bottom of the sliders 61. The power caster 62 is a wheel with its own power output. When the power caster 62 is activated, it drives the slider 61 to move along the first slide rail 11 or the second slide rail 12, thereby moving the placement plate 5 along the first slide rail 11 or the second slide rail 12.

[0045] Reference Figure 4 The second moving mechanism 7 includes a baffle 71, a guide block 72, and a telescopic cylinder 73. Baffles 71 are fixedly installed at both ends of the processing table 2. The first slide rail 11 and the second slide rail 12 are located between the two baffles 71, with the length of the baffle 71 perpendicular to the first slide rail 11. A guide groove 74 is formed along the length of the baffle 71. Guide blocks 72, adapted to the guide groove 74, are fixedly connected to both ends of the placement plate 5. The cross-sectional shape of both the guide groove 74 and the guide block 72 is T-shaped. The telescopic cylinder 73 is fixedly installed at one end of the baffle 71, and the piston rod of the telescopic cylinder 73 horizontally passes through the baffle 71 and extends into the guide groove 74. The telescopic cylinders 73 at both ends of the processing table 2 are staggered. Both the first slide rail 11 and the second slide rail 12 have through grooves 15 for the slider 61 to enter and exit. The through grooves 15 on the first slide rail 11 and the second slide rail 12 are directly opposite each other. A connecting groove 75 is provided on the baffle 71, directly opposite the guide blocks 72 on the two placement plates 5. The size of the connecting groove 75 is the same as that of the guide block 72, and the connecting groove 75 is connected to the guide groove 74. When the guide block 72 is located in the connecting groove 75, the slider 61 is directly opposite the through groove 15.

[0046] The placement plate 5 is driven to move on the first slide rail 11. When the guide block 72 at one end of the placement plate 5 moves into the guide groove 74 through the connecting groove 75, the slider 61 is aligned with the through groove 15. At this time, the telescopic cylinder 73 is activated. The piston rod of the telescopic cylinder 73 pushes the guide block 72 to move along the guide groove 74. The slider 61 moves out of the first slide rail 11 through the through groove 15 on the first slide rail 11 and moves to the second slide rail 12 through the through groove 15 on the second slide rail 12. At this time, the connecting groove 75 is aligned with the guide block 72, and the placement plate 5 can move along the second slide rail 12. The principle is the same when the placement plate 5 moves from the second slide rail 12 to the first slide rail 11. Thus, the placement plate 5 is driven to move between the first slide rail 11 and the second slide rail 12.

[0047] Reference Figure 4 A material collection hole is provided on the processing table 2 and on one side of the material box 3, and a material collection box 91 is placed in the material collection hole. A mounting frame 92 is fixedly installed on the placement table and on one side of the material collection hole. The mounting frame 92 is also an L-shaped rod. The vertical end of the mounting frame 92 is fixedly installed on the side of the processing table 2, and the horizontal end of the mounting frame 92 extends horizontally to the top of the first slide rail 11. A cleaning roller 93 is rotatably installed on the horizontal section of the mounting frame 92. The length direction of the cleaning roller 93 is the same as the length direction of the first slide rail 11.

[0048] After the garment pieces are processed, they are conveyed to one side of the collection box 91 on the first slide rail 11 via the placement plate 5. At this time, the drive pressure plate 511 moves away from the placement plate 5, and the cleaning roller 93 is activated. The cleaning roller 93 cleans and conveys the garment pieces on the placement plate 5 into the collection box 91, so as to facilitate the removal of the processed garment pieces from the placement plate 5.

[0049] The implementation principle of a buttonhole machine for suit production according to an embodiment of this application is as follows: the placement plate 5 on the second slide rail 12 is moved to face the material box 3, and the material taking mechanism 4 takes out the garment pieces one by one from the material box 3. The taken-out garment pieces are transported to the placement plate 5 by the conveyor belt 13. The placement plate 5 is moved to the first slide rail 11 under the drive of the second moving mechanism 7. The first moving mechanism 6 drives the placement plate 5 to move along the first slide rail 11. The garment pieces pass under the buttonhole machine body 1 and are processed. After the garment pieces are processed, the placement plate 5 is moved to the second slide rail 12 by the second moving mechanism 7, and the placement plate 5 is driven to move again to face the material box 3 for feeding. Placement plates 5 are installed on both the first slide rail 11 and the second slide rail 12. The two placement plates 5 move cyclically on the first slide rail 11 and the second slide rail 12 to continuously feed the buttonhole machine body 1, reducing the downtime of the buttonhole machine.
