When the piston rod of the fifth air cylinder 124 extends out and drives the second left clamp mounting plate 122 to move along the eighth slide rail 126, the connecting belt movable plate 130 is connected through the sixth air cylinder 128 to move along the eighth slide rail 126.

A third inductor 143 is provided on the second rail 142. When the right clip device moves to the third sensor 143, the third sensor 143 senses the position information of the right clip device, and controls the half-folding motor 88 to stop.

As shown in fig. 6 and 10. The material receiving mechanism comprises a semi-finished product material receiving device positioned between the material receiving mechanism and the sewing position and a finished product material receiving device positioned below the sewing position. The semi-finished product receiving device comprises a semi-finished product receiving motor 133 mounted below, and an output shaft of the semi-finished product receiving motor 133 drives the semi-finished product discharging plate 135 to ascend and descend along a tenth sliding rail 136 through a turbine box 134. When a semi-finished product is needed, the fifth motor 81 drives the folding mechanism to move to the position above the semi-finished product collecting device. The left and right clamping devices loosen the cloth and drop the cloth onto the semi-finished product discharge plate 135.

The finished product receiving device comprises a receiving cylinder 138 arranged on the frame 1 and a receiving motor 137 arranged on one side of the discharging box 147. The cylinder body of the material receiving cylinder 138 is rotatably connected with the material receiving cylinder mounting base 170. The receiving cylinder mounting base 170 is fixedly connected with the frame 1 through a first fixing base 139. The piston rod of the material receiving cylinder 138 is connected with the material hitting plate 140, the lower end of the material hitting plate 140 is connected with the material receiving shaft through the material receiving connecting block, and two ends of the material receiving shaft are rotatably mounted on the frame 1 through the second fixing seat 141. The material receiving cylinder 138 drives the striking plate 140 to move, and the striking plate 140 presses down the sewn cloth from the sewing position to the discharge box 147. The receiving motor 137 drives the ninth timing belt to rotate. The ninth timing belt is fixedly connected to the finished product discharging plate 148 through a connecting member, and drives the finished product discharging plate 148 to ascend and descend.

The outer walls of the two sides of the discharging box 147 are provided with fourth inductors 144. When the cloth is put in, the light signal between the fourth sensors 144 is blocked, and the material receiving motor 137 is controlled to move, so that the finished product placing plate 148 descends.

Before processing, according to the difference of the cloth width, the fourth motor 62 drives the two sets of clamping devices to approach or separate from each other through the fifth synchronous belt 66, and drives the first material receiving plate 71 and the second material receiving plate 72 to move left and right along the third slide rail 69. The cloth is drawn out from the gap between the first roller 6 and the second roller 7, passes through the first feeding shaft 12 and the second feeding shaft 13 in sequence, passes between the third roller 29 and the fourth roller 28, and is finally placed below the pressing plate 11. During processing, the piston rod of the material pressing cylinder 15 extends out to drive the pressing plate 11 to press the cloth. Then the feeding motor 3 drives the first roller 6 to rotate, and the first motor 14 drives the second feeding shaft 13 to rotate, so as to feed. Meanwhile, the material discharging mechanism is driven by the third motor 51 to move forward to a specified position according to the required cloth length. Then the piston rod of the material pressing cylinder 15 retracts to drive the pressing plate 11 to open. The third motor 51 drives the spitting mechanism to move a distance backwards. When the material discharging mechanism moves backwards, the sixth motor 23 drives the fourth roller 28 to rotate, and the third roller 29 and the fourth roller 28 feed the cloth. The cloth is placed on the first receiving plate 71 and the second receiving plate 72, and the two material clamping devices clamp the cloth through the clamping cylinder 76. Then the cutter motor 38 drives the cutter 37 to rotate, and the second motor 42 drives the cutter motor 38 to move leftwards to cut the material. After the material cutting is finished, the third motor 51 drives the material discharging mechanism to return to the home position, and the second motor 42 drives the cutter motor 38 to return to the home position. The two material clamping devices loosen the cloth. The fifth motor 81 drives the folding mechanism to move backwards, the two ends of the cloth are clamped by the left clamping device and the right clamping device, and the fifth motor 81 drives the folding mechanism to move forwards for a certain distance. The piston rod of the third cylinder 96 is then extended to drive the right gripper device to move to the left and the piston rod of the second cylinder 98 is retracted to drive the right gripper device to move upwardly. The folding motor 88 drives the left clamping device and the right clamping device to be close to each other through a synchronous belt for folding. The fifth motor 81 drives the folding mechanism to move forward to the sewing machine head. The right gripper releases the cloth and the piston rod of the third cylinder 96 retracts, driving the right gripper to move to the right out of the way position. At the same time, sixth cylinder 128 drives platen 130 against the fold. The fifth cylinder 124 drives the pressing plate 130 to move forward, so as to push the cloth forward. The material taking device at the head of the sewing machine takes away the cloth and sends the cloth to be sewn. The fifth motor 81 drives the folding mechanism to reset, and the doubling-up motor 88 drives the left clamp and the right clamp to move away from each other and reset. After sewing, the material receiving cylinder 138 drives the material beating plate 140 to move, and the sewn cloth is pressed down from the sewing position and is sent into the material discharging box 147. The material distribution position is sensed by the two sensors, so that the material receiving motor 137 is controlled to enable the finished product discharging plate 148 to descend through the synchronous belt assembly.
