A pattern cutting machine for clothing production

Abstract

The present application belongs to the technical field of plate printing machine, and particularly relates to a plate printing machine for clothing production, which comprises a rack, a portal frame slidingly arranged on the rack, a machine head slidingly arranged on the portal frame, and a magnetic workbench fixedly arranged on the rack. When the moving seat moves away from the portal frame, the air flow generated by the fan first blows to the surface of the kraft paper to smooth the wrinkles and remove the dust, and then the magnetic attraction belt is synchronously released and adheres to the magnetic workbench to press and fix the edges of the blown paper. Through the air guide mechanism and the winding and unwinding actions, the automatic switching of "blowing dry first and then winding" is realized. When the cross rod rotates with the magnetic attraction belt winding and unwinding, all the blades are synchronously deflected at an angle. When unwinding, the paper is automatically blown flat towards the moving seat advancing direction. When winding, the plate printing ink stains are automatically blown dry towards the moving seat resetting direction, and the paper scraps are removed. The problems of smearing the ink and winding the sundries into the cloth roll during the winding process are completely avoided.

Description

Technical Field

[0001] This invention belongs to the field of pattern making machine technology, and specifically relates to a pattern making machine for garment production. Background Technology

[0002] Pattern making machines are core equipment connecting garment creative design and mass production cutting. They can interface with garment CAD pattern systems, covering the entire production process from new product sampling and sizing to fabric layout. Leveraging high-precision drawing and cutting functions, the equipment can output digital patterns to paper patterns or directly cut fabric with a single click. Compared to manual pattern drawing, it effectively avoids dimensional deviations caused by manual marking, minimizing pattern errors. Collar shapes and curved pieces for complex garments such as suits, evening gowns, and lace can all be formed in one pass.

[0003] Currently, flatbed pattern making machines used in garment production mainly use vacuum adsorption or mechanical pressing to fix kraft paper. Vacuum adsorption requires high table sealing and consumes a lot of energy. Thin kraft paper is easily deformed by the adsorption, resulting in dimensional deviations. Mechanical pressing can easily press irreversible creases into the paper surface, causing the paper to wrinkle and shift, affecting cutting accuracy. Summary of the Invention

[0004] The purpose of this invention is to provide a pattern-making machine for garment production in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions: A pattern-making machine for garment production includes a frame and a gantry frame slidably mounted on the frame. A machine head is slidably mounted on the gantry frame. A magnetic worktable is fixedly mounted on the frame. A movable seat with an opening at the lower end is slidably mounted on the surface of the magnetic worktable. A drive mechanism is provided on both sides of the movable seat and the gantry frame. The movable base is equipped with multiple downward-facing fans. A crossbar is rotatably mounted in the movable base. Magnetic strips that attract to the magnetic worktable are wrapped around both ends of the crossbar. The other end of the magnetic strips is fixed to the magnetic worktable. An air guide mechanism is provided at the lower end of the movable base. A T-shaped frame is connected to the air guide mechanism. A swing mechanism connected to the crossbar is provided inside the movable base. The swing mechanism is connected to the T-shaped frame.

[0006] As a further optimization of the present invention, a take-up reel is fixedly provided at both ends of the crossbar, the magnetic strip is wound on the take-up reel, and a guide wheel is rotatably provided on the movable seat, the guide wheel being connected to the magnetic strip.

[0007] As a further optimization of the present invention, the swing mechanism includes a drive gear, which is fixedly mounted on a crossbar. An extension frame is fixedly mounted inside the movable seat. A horizontal shaft parallel to the crossbar is rotatably mounted on the extension frame. An incomplete gear is fixedly mounted on the horizontal shaft and meshes with the drive gear. A second torsion spring is provided between the horizontal shaft and the extension frame. A first rocker arm is fixedly mounted on the horizontal shaft, and an embedded block is fixedly mounted on the first rocker arm.

[0008] As a further optimization of the present invention, the air guiding mechanism includes an air guiding frame, which is fixedly mounted in a movable seat. Multiple blade shafts are rotatably mounted through the air guiding frame, and blades are fixedly mounted on the blade shafts. Two rocker arms are fixedly mounted on the blade shafts, and connecting rods are provided between the two rocker arms. The connecting rods are rotatably connected to each of the two rocker arms, and the connecting rods are fixedly connected to a T-shaped frame.

[0009] As a further optimization of the present invention, the T-shaped frame includes a horizontal frame, which is fixedly connected to a connecting rod. A vertical frame is fixedly installed on the horizontal frame, and a vertical groove is opened on the vertical frame. The embedded block is slidably installed in the vertical groove.

[0010] As a further optimization of the present invention, the lower end of the movable seat is provided with a flared opening, the upper end of the movable seat is provided with an air vent, the two ends of the inner surface of the movable seat are provided with partitions, and the magnetic strip is provided between the partitions and the movable seat.

[0011] As a further optimization of the present invention, a torsion spring is connected between the two ends of the crossbar and the movable seat.

[0012] As a further optimization of the present invention, the driving mechanism includes a mounting frame, which is slidably mounted on the frame. A servo motor is fixedly mounted on the mounting frame, and a drive rod connected to the servo motor is rotatably mounted on the mounting frame. A drive gear is fixedly mounted at the end of the drive rod.

[0013] As a further optimization of the present invention, guide rails and racks are fixedly provided on both sides of the frame, the mounting bracket is slidably mounted on the frame via the guide rails, and the drive gear meshes with the rack.

[0014] The beneficial effects of this invention are as follows: 1. Unlike existing technologies, in actual use, when the moving seat moves away from the gantry, the airflow generated by the fan first blows onto the surface of the kraft paper to smooth out wrinkles and remove dust. Then, the magnetic strip released simultaneously adheres to the magnetic worktable, pressing and fixing the smoothed paper edges. This completely solves the problem of irreversible creases caused by the traditional mechanical pressing strip "pressing with wrinkles". It realizes the paper laying process of "smoothing first and then magnetically fixing".

[0015] 2. Unlike existing technologies, in actual use, the automatic switching of "drying first and then rewinding" is achieved through the air guide mechanism and the unwinding and rewinding action. When the crossbar rotates with the magnetic belt, it synchronously drives the active gear and incomplete gear of the swing mechanism to mesh and transmit power. Through the rocker arm, the embedded block and the T-shaped frame, the connecting rod is moved laterally, so that all blades deflect at the same angle. When unwinding, the paper is automatically blown flat in the direction of the moving seat. When rewinding, the printing ink stains are automatically blown dry and the cutting paper scraps are removed in the direction of the moving seat reset. This completely avoids the problems of ink stains being smudged and debris being rolled into the cloth roll during the rewinding process. Attached Figure Description

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example 1, such as Figures 1-8 As shown, a pattern-making machine for garment production includes a frame 1, which serves as the basic support structure for the entire machine and ensures the stability of the equipment operation. A gantry frame 2 is slidably mounted on the frame 1. A machine head 14 (composed of cutting, marking, and other devices, which is existing technology and will not be described in detail) is slidably mounted on the gantry frame 2 via an X-axis electric slide rail. This machine head 14 is used to complete the pattern cutting and marking operations of kraft paper. A magnetic worktable 11 is fixedly mounted on the upper surface of the frame 1. The magnetic worktable 11 is a metal table surface with a magnetic steel plate embedded in its surface. It has a high degree of flatness and is used to support the kraft paper to be cut. The gantry frame 2 is used to drive the machine head 14 to move along the Y-axis direction, covering the entire magnetic worktable 11.

[0020] like Figures 3-4 As shown, a movable seat 4 with an open lower end is slidably mounted on the surface of the magnetic worktable 11. This seat serves as an integrated mounting carrier for auxiliary mechanisms such as blowing, unwinding, and air guiding, and can reciprocate along the length of the worktable. Both the movable seat 4 and the gantry 2 are equipped with drive mechanisms 3 on both sides to provide high-precision movement power. Multiple downward-facing fans 10 are fixedly mounted on the top of the movable seat 4, equidistantly arranged along its length to generate directional airflow, smoothing wrinkles, removing dust, and drying ink stains. A crossbar 6 is rotatably mounted in the middle of the movable seat 4, with magnetic strips 5 wrapped around both ends to attract the magnetic worktable 11. The magnetic strips 5 are flexible rubber magnetic strips with suitable attraction force. It will not damage the surface of the kraft paper and can evenly press the edges of the paper to prevent displacement during cutting. The magnetic worktable 11 provides an adsorption base for the magnetic strip 5, which can fix the material without a vacuum system. The other end of the magnetic strip 5 is fixedly set on the edge of the magnetic worktable 11 near the gantry 2, realizing a structure where one end is fixed and the other end moves with the moving seat 4. The lower opening of the moving seat 4 is provided with an air guide mechanism 9, which is used to adjust the blowing direction of the airflow of the fan 10 to adapt to the blowing needs of different working conditions. A T-shaped frame 8 is connected to the air guide mechanism 9. The moving seat 4 is provided with a swing mechanism 7 connected to the crossbar 6. The swing mechanism 7 is connected to the T-shaped frame 8 to convert the rotational motion of the crossbar 6 into the linear motion of the T-shaped frame 8, realizing the automatic switching of the air guide direction.

[0021] like Figure 6As shown, a take-up reel 51 is fixedly installed at both ends of the crossbar 6. The magnetic tape 5 is wound around the take-up reel 51 to neatly store the magnetic tape 5 and prevent it from tangling. A guide wheel 52 is rotatably installed on the inner wall of the movable seat 4. The guide wheel 52 is located below the take-up reel 51. After the magnetic tape 5 passes around the guide wheel 52, it extends downward to the surface of the magnetic worktable 11 to change the direction of the magnetic tape 5 and ensure that the magnetic tape 5 can be flat and attached to the magnetic worktable 11.

[0022] like Figure 5 and Figure 7 As shown, the swing mechanism 7 includes a drive gear 71, which is fixedly mounted in the middle of the crossbar 6 and rotates synchronously with the crossbar 6 to output rotational power. An extension frame 72 is fixedly mounted on the inner wall of the movable seat 4. A horizontal shaft 73 parallel to the crossbar 6 is rotatably mounted on the extension frame 72 to transmit the power of the drive gear 71. An incomplete gear 74 is fixedly mounted on the horizontal shaft 73. The incomplete gear 74 meshes with the drive gear 71, and the limit of the air guide angle is achieved through the cooperation of the toothed and toothless sections. The horizontal shaft 73 and... A second torsion spring 731 is provided between the extension frames 72. One end of the second torsion spring 731 is fixed to the horizontal shaft 73, and the other end is fixed to the extension frame 72. It is used to provide a restoring force when the incomplete gear 74 disengages from the driving gear 71, so that the incomplete gear 74 always maintains the tendency to contact the driving gear 71. A rocker arm 75 is fixedly provided at the end of the horizontal shaft 73. A cylindrical insert block 751 is fixedly provided at the end of the rocker arm 75 away from the horizontal shaft 73. It is used to convert the rotational motion of the horizontal shaft 73 into the linear motion of the T-shaped frame 8.

[0023] like Figures 4-5 and Figure 8 As shown, the air guiding mechanism 9 includes an air guiding frame 91, on which multiple blade shafts 921 are rotatably mounted. The multiple blade shafts 921 are equidistantly arranged along the length of the air guiding frame 91. Each blade shaft 921 is fixedly equipped with a blade 92 to change the blowing direction of the airflow. The air guiding frame 91 is a rectangular frame structure and is fixedly installed at the lower opening of the movable seat 4 to provide installation support for the blades 92 and blade shafts 921. Each blade shaft 921 has a rocker arm 93 fixedly mounted at its end. All rocker arms 93 are connected by a connecting rod 94. The connecting rod 94 is rotatably connected to the end of each rocker arm 93 to achieve synchronous deflection of all blades 92 and ensure that the wind direction of the entire working surface is consistent. The connecting rod 94 is fixedly connected to the T-shaped frame 8 to receive the power transmitted by the T-shaped frame 8.

[0024] like Figure 8As shown, the T-shaped frame 8 includes a horizontal frame 81 and a vertical frame 82. The horizontal frame 81 is arranged horizontally, and its middle part is fixedly connected to the connecting rod 94 to drive the connecting rod 94 to move synchronously. The vertical frame 82 is vertically fixed to the middle part of the horizontal frame 81. A vertical groove 821 is opened on the vertical frame 82. An embedded block 751 is slidably disposed in the vertical groove 821. The diameter of the embedded block 751 is clearance-fitted with the width of the vertical groove 821 to convert the arc motion of the rocker arm 75 into the linear motion of the T-shaped frame 8 and avoid motion interference.

[0025] like Figures 3-4 As shown, a flared mouth 42 is fixedly installed at the lower opening of the movable seat 4, and the air guide frame 91 is located inside the flared mouth 42 to gather the airflow generated by the fan 10, thereby improving the airflow speed and blowing effect. Multiple air ports 41 are opened at the upper end of the movable seat 4, and the multiple air ports 41 are arranged in a matrix to ensure air circulation inside and outside the movable seat 4 and provide sufficient air intake for the fan 10. Vertical partitions 43 are fixedly installed at both ends of the inner surface of the movable seat 4, and the magnetic suction belt 5 is set in an independent channel between the partition 43 and the side wall of the movable seat 4 to avoid airflow interference with the operation of the magnetic suction belt 5 and to ensure that the magnetic suction belt 5 can be smoothly extended and retracted and fit tightly.

[0026] like Figure 6 As shown, torsion springs 61 are connected between the two ends of the crossbar 6 and the inner wall of the movable seat 4. One end of the torsion spring 61 is fixed on the crossbar 6, and the other end is fixed on the inner wall of the movable seat 4. After unwinding and storing force, the torsion spring 61 provides power for the winding magnetic belt 5, which can automatically compensate for the change in the diameter of the magnetic belt 5, maintain constant tension throughout the process, and avoid paper stretching and deformation.

[0027] like Figure 3 As shown, the drive mechanism 3 includes a mounting frame 31, and guide rails 12 are fixedly installed on both sides of the frame 1. The mounting frame 31 is slidably mounted on the guide rails 12 on both sides of the frame 1 via a slider. A servo motor 32 is fixedly installed on the mounting frame 31 to provide high-precision, adjustable-speed power output. The output shaft of the servo motor 32 is connected to a drive rod 33 via a gear set, and a drive gear 331 is fixedly installed at the end of the drive rod 33. A rack 13 is fixedly installed on both sides of the frame 1. The drive gear 331 and the rack 13 mesh with each other. The guide rails 12 ensure smooth movement, and the rack 13 has strong transmission load capacity and high positioning accuracy, ensuring that the movement accuracy of the moving seat 4 and the gantry 2 meets the requirements for pattern making.

[0028] It should be noted that the working process of this pattern-making machine used for garment production is as follows: In the initial state, the movable seat 4 and the gantry 2 are located on the same side of the frame 1 in the initial position, the magnetic belt 5 is wound on the winding reels 51 at both ends of the crossbar 6, and the incomplete gear 74 and the driving gear 71 are in the initial meshing position. During operation, the kraft paper to be cut is laid flat on the surface of the magnetic worktable 11. After aligning with the positioning marks, the equipment is started. The servo motor 32 of the drive mechanism 3 drives the drive rod 33 and drive gear 331 to rotate, driving the mounting frame 31 and the moving seat 4 to move away from the gantry 2 along the rack 13. The magnetic strip 5 fixed on the magnetic worktable 11 is pulled out, guided by the guide wheel 52, and runs independently under the separation of the partition 43. This drives the winding reel 51 and the crossbar 6 to rotate against the resistance of the torsion spring 61, while simultaneously storing force for the torsion spring 61. The drive gear 71 on the crossbar 6 rotates synchronously, meshing and driving the horizontal shaft 73 and the incomplete gear 74 to rotate. The horizontal shaft 73 drives the rocker arm 75 to rotate, causing the embedded block 751 to slide in the vertical groove 821, pushing the T-shaped frame 8 to move laterally. The T-shaped frame 8 drives all the rocker arms 93 to rotate synchronously through the connecting rod 94, causing the blade 92 to deflect forward to the optimal position required for unwinding. At the same time, the fan 10 inside the moving seat 4 starts, and the airflow enters through the upper air port 41 and converges at the lower horn port 42. After being deflected, the airflow is blown at an angle onto the kraft paper surface in front of the moving seat 4, first smoothing out the wrinkles and removing the floating dust. Then, the magnetic suction belt 5 is released synchronously and adheres to the magnetic worktable 11, pressing and fixing the smoothed kraft paper edge. When the drive gear 71 rotates to face the toothless section of the incomplete gear 74, the two disengage. The torsion spring 731 drives the incomplete gear 74 to maintain the reset trend, so that the tooth end of the incomplete gear 74 is always in contact with the tooth surface of the drive gear 71, thereby keeping the blade 92 at the optimal blowing angle. The moving seat 4 stops after reaching the end of the stroke. The magnetic suction belt 5 completes the edge fixing of the entire kraft paper. The gantry 2 moves along the guide rail 12, driving the machine head 14 to complete the plate cutting and inkjet marking operations on the kraft paper according to the preset CAD data. After the pattern is completed, the drive mechanism 3 drives the moving seat 4 to reset towards the gantry 2. The torsion spring 61 releases its stored elastic potential energy, causing the crossbar 6 and the winding reel 51 to rotate in the opposite direction. The magnetic tape 5 is automatically wound up. When the crossbar 6 rotates in the opposite direction, the drive gear 71 re-engages and drives the incomplete gear 74 to rotate in the opposite direction. The horizontal shaft 73 drives the rocker arm 75 to rotate in the opposite direction, causing the embedded block 751 to slide in the opposite direction in the vertical slot 821. This pulls the T-shaped frame 8 to move laterally in the opposite direction. The T-shaped frame 8 drives all the rocker arms 93 to rotate in the opposite direction through the connecting rod 94. The blades 92 are deflected backward to the optimal angle required for winding. The airflow generated by the fan 10 blows the deflected blades 92 onto the kraft paper surface in front of the moving seat 4, first drying the ink stains left by the printing and removing residual paper scraps. Then the magnetic tape 5 is neatly retracted by the winding reel 51 to prevent ink stains and debris from getting into the cloth roll. When the moving seat 4 returns to the initial position, the incomplete gear 74 and the drive gear 71 return to the initial meshing position, the blades 92 return to the vertical state, and the fan 10 stops running, completing a complete work cycle.

[0029] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
