The sewing speed is fast and the production efficiency is significantly improved. The rising and falling needles are easy to control during the sewing process. The seam position of the Bao Arrow is relatively uniform, the looseness during the sewing process is appropriate, the tip of the Bao Arrow after sewing is flat, the pioneer is smooth and straight, the appearance of the sewn product is high, the customer satisfaction is high, and the operation difficulty is low, and the operator is easy to get started during operation.

[0018] Further, the translation mechanism 5 includes a translation cylinder 51 and a translation slide 52. The translation cylinder 51 adopts the structure used in the prior art. The finished product can be directly purchased according to the power size and stroke used. Two translation slides 53 that are recessed downward are processed in parallel at intervals on the workbench. The translation slide 53 is arranged along the feeding direction of the feeding template 3. A slider 54 matching the translation slide 53 is arranged below the translation slide 52. The slider 54 is slidably installed in the translation slide 53. The push mechanism 6 is installed on the translation slide 52. When in use, the piston rod of the translation cylinder 51 is controlled to extend or shorten, so that the translation slide 52 can be controlled to slide back and forth along the translation slide. Preferably, in order to ensure that the translation slide 52 slides stably in the translation slide 53, so that it always maintains a straight line slide, and improves the accuracy of feeding, the cross-sectional shape of the translation slide 53 is a rectangular structure, and guide rails are arranged on both sides of the translation slide 53. Both sides of the slider 54 slide with the rails.

[0019] Furthermore, the pushing mechanism 6 includes a pushing cylinder 61 and a pushing slide 62. The pushing cylinder 61 adopts the structure used in the prior art and can be directly purchased as a finished product according to the power size and stroke used.

[0020] Furthermore, the template transmission mechanism 7 includes a mounting plate 71, a supporting arm 72, a power cylinder 73 and a positioning plate 74. The power cylinder 73 adopts the structure used in the prior art and can be directly purchased as a finished product according to the power size and stroke used. The mounting plate 71 is mounted on the push slide 62, the supporting arm 72 is mounted on the mounting plate 71, and the positioning plate 74 is mounted on the end of the supporting arm 72. Two strip holes 75 are vertically symmetrically processed on the positioning plate 74 on both sides of the supporting arm 72, and sliding parts are installed in the strip holes 75. There are two power cylinders 73 and they are located on both sides of the supporting arm 72. The cylinder seat of the power cylinder 73 is installed above the positioning plate 74, and the piston rod of the power cylinder 73 is connected to the sliding part. The sewing template 4 is mounted on the sliding part. When in use, the power cylinder When the piston rod of the cylinder 73 is extended, the sewing template 4 can be driven downward through the sliding member. Conversely, when the piston rod of the power cylinder 73 is shortened, the sewing template 4 can be driven upward through the sliding member. Preferably, the sliding member includes a guide rod 76, a movable block 77 and a connecting plate 78. The guide rod 76 is vertically installed in the strip hole 75, and the movable block 77 is slidably installed on the guide rod 76. The movable block 77 is connected to the piston rod of the power cylinder 73. The sewing template 4 is detachably installed at the bottom of the horizontal section of the connecting plate 78. The sewing template 4 slides up and down on the guide rod 76 through the movable block and the connecting plate. It runs smoothly, which can ensure that the sewing template 4 is in a straight line running state during the process of moving up or down, which is conducive to ensuring the accurate positioning of the sewing machine 2, thereby improving the sewing quality of the arrow. Preferably, in order to meet the sewing requirements of Bao arrow fabrics of different thicknesses, the connecting plate 78 is vertically processed with an adjusting groove 79 corresponding to the movable block 77, and the movable block 77 is fixedly installed with a screw rod 710. The screw rod 710 passes through the adjusting groove 79 and is connected and fixed to the connecting plate 78 by a nut. The height of the connecting plate 78 can be adjusted through the adjusting groove 79, thereby changing the height of the sewing template 4 pressed down to adapt to the positioning and sewing of Bao arrow fabrics of different thicknesses and improve the application range of the device. By loosening the nut, the connecting plate 78 can be moved up and down. After moving to the appropriate position, the nut can be tightened. The operation is relatively simple and convenient.
