[0002] A pocket patch sewing machine is a device that sews cloth bags onto clothing. The prepared pockets are placed on the clothing for automatic sewing. Existing pocket patch machines usually complete sewing by manual loading, but manual placement is prone to deviations and has high labor costs.

[0003] At present, a Chinese patent with announcement number CN218372752U discloses an automatic bottom liner shearing and feeding device for automatically cutting the bottom liner and feeding it into a bag pasting machine, including a bottom liner material feeding assembly, a bottom liner material cutting assembly and a bottom liner feeding assembly. The bottom liner feeding assembly includes a bottom liner transfer assembly, a bottom liner support plate and a bottom liner support plate driving device. The bottom liner transfer assembly includes a transfer vacuum suction cup and a driving member for driving it to move back and forth.

[0004] The above patent still has shortcomings. The above transfer vacuum suction cup can only suck and move the cloth exposed from the backing material cutting component.

[0026] The specific implementation modes of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp.

[0027] A base lining automatic shearing and feeding device comprises a machine platform 1, on which a raw material feeding component 2, a cutting component 3, a transfer component 4 and a finished product feeding component 5 are arranged, the cutting component 3 comprises a forming die 6, a cutting cylinder 7 and a forming cutter 8 arranged at the output end of the cutting cylinder 7, the forming die 6 is provided with a forming groove 9 for the forming cutter 8 to pass through, the shape of the forming groove 9 is consistent with the shape of the forming cutter 8 and the base lining finished product, the front and rear sides of the forming die 6 are provided with through grooves 10 for the base lining raw material to pass through, and the through grooves 10 are provided for the base lining raw material to pass through. The groove 10 intersects with the forming groove 9. When the cutting cylinder 7 drives the forming cutter 8 to move upward, the forming cutter 8 cuts the finished lining from the lining raw material. The raw material feeding assembly 2 drives the lining raw material to move in the through groove 10, and cooperates with the forming cutter 8 to complete the cutting of the finished lining. The finished lining is cut out by the forming cutter 8 in cooperation with the forming groove 9 and ejected from the top of the forming groove 9. A horizontal material transfer platform 11 is formed on the top of the forming mold 6, and the transfer assembly 4 moves the finished lining from the material transfer platform 11 to the finished product feeding assembly 5.

[0028] The transfer component 4 includes a first cylinder 12 and a second cylinder 13. A mounting block 14 is provided on the machine 1. The first cylinder 12 is fixedly connected to the mounting block 14. A connecting plate 15 is provided at the output end of the first cylinder 12. The second cylinder 13 is fixedly provided on the connecting plate 15. A pressing plate 16 is also provided at the output end of the second cylinder 13. Sandpaper is attached to the bottom of the pressing plate 16. When the finished base lining needs to be removed, the second cylinder 13 drives the pressing plate 16 to move toward the material transfer platform 11 and press the finished base lining. The first cylinder 12 drives the second cylinder 13 and the finished base lining to move toward the finished product feeding component 5. A slider 17 is also provided at the side end of the mounting block 14. A slide rail 18 is also provided on the connecting plate 15. The slide rail 18 is slidably connected to the slider 17. Through the cooperation between the slide rail 18 and the slider 17, the translation accuracy of the finished base lining is increased, and the position deviation of the base lining caused by the tilted installation of the first cylinder 12 is prevented, thereby causing the problem of reduced sewing accuracy of the base lining.

[0029] The raw material feeding assembly 2 includes a driving motor 19, a feeding roller 20 and a feeding roller 21. The driving motor 19 is arranged on the machine table 1, and its output end passes through the mounting block 14 and is fixed to the feeding roller 20. The feeding roller 21 is rotatably arranged on the mounting block 14 and cooperates with the feeding roller 20 to press the base lining raw material. The feeding roller 20 and the feeding roller 21 are both provided with knurling, and the knurling increases the surface roughness of the feeding roller 20 and the feeding roller 21, thereby preventing the problem of slipping during feeding.

[0030] The machine 1 is also provided with a transverse movement component 22, which includes a driving motor 23, a screw 24 and a slide 25. One end of the screw 24 is fixedly arranged at the output end of the driving motor 23, and the other end is fixed by a bearing seat. The slide 25 and the screw 24 are threadedly matched. When the screw 24 rotates, the slide 25 moves along the central axis direction of the screw 24. The cutting cylinder 7 is fixedly arranged at the bottom of the slide 25. The mounting block 14, the transfer component 4, the forming mold 6, and the raw material feeding component 2 are all arranged above the slide 25. The raw material feeding component 2, the cutting component 3, the transfer component 4 and the finished product feeding component 5 are symmetrically arranged on the left and right sides of the machine 1. The threads on both sides of the screw 24 are opposite, and slides 25 are arranged on both sides, so that two base lining products can be cut at one time and sent to the pocket sticking machine, and the pockets on both sides can be sewn simultaneously.

[0031] The raw material feeding assembly 2 also includes a barrel 26, and the backing material is wound in the barrel 26. A mounting rod 28 is also provided at the side end of the barrel 26. An air avoidance groove 27 is opened on the machine table 1. The mounting rod 28 passes through the air avoidance groove 27 and is fixedly connected to the slide 25. The backing material enters between the feed roller 1 20 and the feed roller 2 21 from the barrel 26, and then enters the molding mold 6. By setting the barrel 26 and fixing it on the slide 25, the slide 25 drives the barrel 26 to move when it moves, thereby preventing the backing material from twisting and folding when the slide 25 moves, resulting in defective products during sewing.

[0032] The finished product feeding assembly 5 includes suction platforms 29 symmetrically arranged on both sides and a linear cylinder 30 for driving the suction platforms 29 to move up and down. The linear cylinder 30 is fixedly arranged on the machine 1, and a mounting plate 31 is arranged at its output end. Both suction platforms 29 are fixed on the mounting plate 31. A negative pressure cavity is provided inside the suction platform 29, and the negative pressure cavity is connected to the air pump. When the transfer assembly 4 pushes the finished base lining onto the suction platform 29, the air pump sucks the finished base lining onto the suction platform 29, thereby preventing the finished base lining from being displaced and falling off when the suction platform 29 moves.

[0033] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementations. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
