Description

Technical Field

[0001] This utility model relates to the field of garment processing equipment technology, and in particular to a placket sewing machine. Background Technology

[0002] The placket of a polo shirt refers to the central front area of ​​the garment, which is usually used for opening and closing, making it easier to put on and take off the garment. It can also be used for decoration. The design and treatment of the placket play an important role in the overall appearance and function of the polo shirt. Knitted polo shirts usually need to have buttons added to the placket to achieve the opening and closing function.

[0003] In related technologies, the opening process of garment plackets mainly utilizes automatic template sewing machines. Specifically, folded garment fabric and placket fabric are placed on a worktable and pressed firmly to define their positions. A sewing device then sews a U-shaped stitch onto the garment and placket fabrics. Finally, a cutting device cuts the garment and placket fabrics apart from the middle of the U-shaped stitch, completing the opening process. However, for plackets with overlapping plackets (where the left and right plackets overlap to form a fold), buttons are typically used to connect the plackets. Scissors are then used to cut the fabric at the opening between the corresponding stitches. This traditional manual opening process is inconvenient and lacks automation.

[0004] In view of this, the inventors of this case conducted in-depth research on the above-mentioned problems, which led to the creation of this case. Utility Model Content

[0005] The purpose of this invention is to provide a placket sewing machine with high processing efficiency and good sewing effect.

[0026] Reference Figures 1 to 7

[0027] A placket sewing machine includes a frame 1 and a sewing machine 2 mounted on the frame 1. The frame 1 is provided with a shaping area 11, a feeding area 12 and a sewing and cutting area 13 arranged sequentially from one end to the other. The sewing machine 2 is mounted in the sewing and cutting area 13 and is used to sew one or more seams on the placket piece.

[0028] The frame 1 is also equipped with a feeding device that drives the placket piece forward. The feeding device is set on the feeding area 12 and transports the garment fabric and placket fabric on the shaping area 11 to the sewing and cutting area 13. The feeding device includes a first moving mechanism 31, a first lifting mechanism 32 set on the first moving mechanism 31 and movable along the length direction of the first moving mechanism 31, and a pressure plate 33 installed at the bottom of the first lifting mechanism 32. The pressure plate 33 is used to press and fix the garment fabric. A through groove 331 is provided in the middle of the pressure plate 33, and a placket pressure rod 332 for pressing and fixing the placket fabric set on the garment fabric is provided in the middle of the through groove 331. The pressure plate 33 and the placket pressure rod 332 are integrally formed.

[0029] Furthermore, it also includes an auxiliary feeding device installed on the frame 1. The auxiliary feeding device includes an air suction hole 41 installed in the shaping area 11, an air blowing hole 42 installed in the sewing and cutting area 13, and a conversion mechanism 43 that connects the air suction hole 41 and the air blowing hole 42 respectively. The side wall of the conversion mechanism 43 is provided with an air dissipation hole 431. The conversion mechanism 43 is provided with a first conversion cylinder 411, a second conversion cylinder 421, an air suction pipe interface 412, and an air blowing pipe interface 422. The air suction pipe interface 412 is connected to the air suction hole 41 through an air suction pipe, and the air blowing pipe interface 422 is connected to the air blowing hole 42 through an air blowing pipe. When the device is running, the motor operates, generating vacuum airflow, which reaches the conversion mechanism 43 through the vacuum tube. The opening and closing of the conversion mechanism 43 acts on the suction port 41 or the blowing port 42 through the vacuum tube. The conversion mechanism 43 controls the vacuum level by closing and contracting the conversion cylinder, which reaches the suction port 41 or the blowing port 42 through the vacuum tube connector. When the conversion mechanism 43 is opened, the vacuum airflow is released through the venting port 43. During operation, the first conversion cylinder 411 is open and the second conversion cylinder 421 is closed, generating vacuum airflow on the inner surface of the housing. When the conversion mechanism 43 cancels the positioning operation, the first conversion cylinder 411 is closed and the second conversion cylinder 421 is opened, releasing the vacuum airflow through the venting port 43, and the surface no longer generates vacuum airflow. This is used for the conversion and cycle of positioning and canceling positioning operations. Its main function is to hold the placed placket and body pieces tightly in position, waiting for the next operation of the feeding device.

[0030] Furthermore, it also includes a fabric gripping device, which includes an X-axis fixed seat 51, which is mounted on an X-axis mounting base 52. Two lever cylinders 53 are mounted on the side wall of the X-axis fixed seat 51. The lever cylinders 53 are connected to a fabric support base 54. A fabric support cylinder 55 is mounted on the bottom of the fabric support base 54. A lever shaft 56 is rotatably connected between the inner walls of the X-axis fixed seat 51. A pressure stabilizing spring is sleeved on the lever shaft 56. Two machine arm fixed seats are mounted on the lever shaft 56. A left lever machine arm 57 and a right lever machine arm 58 are mounted on the side walls of the two machine arm fixed seats. A fabric gripping arm 59 is mounted at the front end of the left lever machine arm 57 and the right lever machine arm 58 and the fabric gripping arm 59. A machine arm spring is provided between the left lever machine arm 57 and the right lever machine arm 58 and the fabric gripping arm 59. The X / Y axis running device controls the horizontal movement of the equipment according to the operating program. During operation, the lever cylinder 53 is in the open state, and the lever shaft 56 acts on the arm fixing seat to raise the fabric grabbing arm 59 and the right lever arm 58 / left lever arm 57. The X-axis fixing seat is installed on the X-axis mounting seat of the equipment. When the equipment moves to the designated position and needs to grab the cut piece, the lever cylinder 53 closes to control the fabric grabbing arm to press down and grab the cut piece in the same way. The arm spring controls the front and rear balance of the arm after grabbing the fabric. After grabbing the cut piece, the fabric support cylinder works, and the left lever arm 57 is pushed to the left by a designated distance through the fabric support base to tighten the surface of the cut piece in this way, ensuring the tension of the fabric and improving the sewing effect. After the sewing process is completed, the fabric support cylinder closes and the left lever arm 57 retracts. The pressure stabilizing spring has the function of rebounding and stabilizing the left lever arm 57.
