Then the front-back displacement motor 6311 drives the staggered bearing plate 6313 to reset, and the above-mentioned operation is repeated to realize the continuous forward movement of the card strip until the last first clamping groove 622 of the first auxiliary plate 62 is reached. Different from other positions, the last second clamping groove 63222 of the staggered plate 63221 is lifted to hang the card strip, and then the card strip is driven forward, and the like. Figure 11 As shown, the last second clamping groove 63222 of the staggered plate 63221 enters the upper side of the first opening 6422, and then the up-down lifting cylinder 6321 resets, and the card strip falls into the first containing groove 6421 of the pushing die 642.

[0089] With the push block 644 constantly pushing the card strip forward, the card strip enters the placement part 722 at the end of the delivery channel 721 of the delivery mold 72, at this time the blocking cylinder 771 is in the starting state, the clamping blocking piece 772 is extended to the placement part 722 at the end of the delivery channel 721 to cooperate with the blocking card strip to avoid falling, at the same time the second sensor 78 senses that the card strip reaches, the clamping cylinder 76 is opened to make the first clamping piece 761 and the second clamping piece 762 separate, the clamping lifting cylinder 741 is started to mobilize the first clamping piece 761 and the second clamping piece 762 to move down, then the clamping cylinder 76 is tightened, so that the first clamping piece 761 and the second clamping piece 762 clamp the card strip, then the blocking cylinder 771 resets, the clamping blocking piece 772 is away from the opening position of the delivery channel 721, the push cylinder 73 is started, the movable main seat 731 is driven to move forward, so that the card strip advances, and finally the card strip is sent to the sewing area of the sewing machine 4 to be sewn with the cover, the four-axis conveying mechanism keeps pressing the cover during the sewing process, and the sewing machine (4) moves along the sewing track to cooperate with the sewing machine to sew, each group of cylinders resets to complete a feeding action, and the feeding operation of the card strip is repeatedly completed;

[0090] When the first card strip and the cover are sewn, the four-axis conveying mechanism 5 moves the cover that has completed the first sewing out of the sewing area, and part of the cover may need to be sewn with a second card strip at another position. At this time, the rotating motor 551 of the four-axis conveying mechanism 5 drives the pressing piece 552 to rotate by a certain angle together with the cover, adjusts the direction of the cover, so that the area of the cover that needs to be sewn secondly faces the sewing machine 4, and then the cover is moved to the sewing area to be sewn secondly.

[0091] After the card strip and the cover are sewn and fixed, the four-axis conveying mechanism 5 moves the finished product out of the sewing area of the sewing machine 4, the unloading cylinder 81 is started to extend the unloading pressing seat 82, then the unloading pressing cylinder 83 drives the unloading pressing block 84 to press down and press the finished product, the unloading cylinder 81 resets to drive the unloading pressing block 84 to move to the unloading port 11, until the finished product falls into the first collecting box 85 from the unloading port 11, when the first collecting box 85 is full, the unloading auxiliary cylinder 87 is started to lift the unloading slide 88, so that one end of the unloading slide 88 is arranged below the unloading port 11, and the other end is arranged above the auxiliary slide 89, when the finished product falls from the unloading port 11, the finished product can fall into the second collecting box 86 along the unloading slide 88 and the auxiliary slide 89 in turn, at this time, the first collecting box 85 that is full can be removed to replace an empty box, so that the continuous operation mode does not need to be stopped.
