A second reset member 66 is fixedly connected between the opposite side of the two sliders 64 and the inner wall of the mounting groove 511. The second reset member 66 is preferably a spring. The second reset member 66 is used to push the slider 64 to move in the mounting groove 511, so that the slider 64 moves closer The middle position of the mounting plate 51 is pushed, and the extension column 65 moves synchronously with the slider 64. Under the action of the extension column 65, the rotating rod 62 is driven to rotate, so that the two rotating rods 62 are in an eight-shaped design in the initial state. During the descending process of the support plate 54, the first roller 63 contacts the waist circumference 12 on the diaper body 1, and then the support plate 54 continues to descend, and the first roller 63 rolls at the waist circumference 12, causing the two rotating rods 62 to rotate away from each other. Under the action of the rotating rod 62 and the first roller 63, the laser punched areas on the waist circumference 12 are flattened to avoid wrinkles that affect the laser punching effect. The flattening mechanism 6 is set on both sides of the laser punching device 52, and will not affect the laser punching operation of the laser punching device 52 on the waist circumference 12.

[0054] In this embodiment, if Figure 5As shown, the inner bottom end of the diaper retaining cavity 31 is located at the laser drilling operation site and is provided with a waste residue groove 33. The front and rear ends of the diaper fixing seat 3 are both provided with a slag discharge groove 34 that communicates with the waste residue groove 33. The slag discharge mechanism 8 includes a suction cover 81 corresponding to the position of the slag discharge groove 34. The suction cover 81 is fixedly connected to a suction pipe 84, and the suction pipe 84 is connected to the slag discharge suction device. A pair of second guide rods 82 are fixedly connected to the side of the suction cover 81 away from the diaper fixing seat 3. The mounting frame 4 is provided with guide holes corresponding to the positions of the second guide rods 82. , one end of the second guide rod 82 slides through the guide hole and is threadedly connected to the limit nut. A third reset member 83 is sleeved between the limit nut and the mounting bracket 4 and on the outside of the second guide rod 82. The third reset member 83 is preferably a spring. The top of the suction cover 81 is fixedly connected to a lower adjustment block 85. An upper adjustment block 86 is provided above the lower adjustment block 85. The top of the upper adjustment block 86 is fixedly connected to a connecting rod 87. The top of the connecting rod 87 is fixedly connected to the support plate 54 through a second connecting plate 88. The lower adjustment block 85 and the upper adjustment block are fixedly connected. The opposite side of the block 86 is provided with a matching sliding inclined surface. When the suction cover 81 is in the initial state, the second guide rod 82 is pushed to move toward the outside of the mounting frame 4 in the guide hole through the action of the third reset member 83, and the suction cover 81 is driven to move closer to the mounting frame 4 through the second guide rod 82. At this time, the suction cover 81 and the diaper fixing seat 3 are separated and will not affect the transportation of the diaper fixing seat 3. When the diaper fixing seat 3 is transported to the suction cover 81, the support plate 54 is lowered, driving the upper adjustment block 86 to move downward, and the upper adjustment block 86 is driven downward. The node block 86 contacts the lower adjusting block 85, and the upper adjusting block 86 slides with the inclined surface of the lower adjusting block 85, thereby pushing the lower adjusting block 85 to move toward the diaper fixing seat 3, and the suction cover 81 is driven to move toward the diaper fixing seat 3 by the lower adjusting block 85. The suction cover 81 is against the outer wall of the diaper fixing seat 3 and covers the outer side of the slag discharge groove 34. The waste residue generated by the laser drilling operation falls into the waste residue groove 33, and the waste residue in the waste residue groove 33 is sucked out of the slag discharge groove 34 through the operation of the slag discharge suction equipment.

[0055] The working principle of the present invention is as follows: when working, the diaper is placed in the diaper retaining cavity 31 of the diaper body 1 and limited. The vacuum device works on the vacuum suction table 32 to absorb and fix the diaper retaining cavity 31. The five vacuum suction tables 32 are positioned, one of which absorbs and fixes the diaper body 1, and the other four absorb and fix the left and right ends of the two waistlines 12 respectively, thereby improving the absorption and fixation effect of the diaper. Then the conveying table 2 works to convey the diaper fixing seat 3. When the diaper fixing seat 3 is conveyed to the bottom of the laser punching device 52, the conveying table 2 stops working.

[0056] The driving member 55 is used to drive the support plate 54 to move downward longitudinally, and drive the laser punching device 52 to move downward close to the diaper body 1. The support rod 72 moves downward synchronously with the support plate 54, so that the support rod 72 is inserted into the adjustment slot 741 of the adjustment sleeve 74. The two sides at the top of the adjustment slot 741 expand outward, and the second roller 73 on the support rod 72 contacts and rolls with the side wall of the adjustment slot 741 to guide the support rod 72 into the adjustment slot 741. During this process, the diaper fixing seat 3 slides on the support rod 36 through the sliding sleeve 37, which can fine-tune the position of the diaper fixing seat 3, and is used to locate the relative position of the diaper fixing seat 3 and the laser punching device 52, so as to ensure the consistency of the laser punching position of the diaper.

[0057] At the same time, the flattening mechanism 6 moves downward synchronously with the support plate 54, and the first roller 63 contacts the waistline 12 on the diaper body 1. As the support plate 54 continues to descend, the first roller 63 rolls at the waistline 12, causing the two rotating rods 62 to rotate away from each other. Under the action of the rotating rods 62 and the first roller 63, the laser-punched areas on the waistline 12 are flattened to avoid wrinkles that affect the laser punching effect.

[0058] At the same time, the upper adjusting block 86 moves downward synchronously with the support plate 54, and the upper adjusting block 86 contacts the lower adjusting block 85. The upper adjusting block 86 slides with the inclined surface of the lower adjusting block 85, thereby pushing the lower adjusting block 85 to move toward the diaper fixing seat 3. The suction cover 81 is driven to move toward the diaper fixing seat 3 through the lower adjusting block 85. The suction cover 81 is against the outer wall of the diaper fixing seat 3 and covers the outer side of the slag discharge groove 34. Then, the laser drilling equipment 52 works to perform laser drilling on the waist 12 to form a ventilation hole 121. The waste residue generated by the laser drilling operation falls into the waste residue groove 33 and is sucked out by the slag discharge. The equipment works to suck out the waste residue in the waste residue trough 33 from the waste residue discharge trough 34 and discharge it away, so as to prevent the waste residue after laser drilling from being retained on the diaper holder 3 and affecting the subsequent processing of diapers. After the diaper processing on the diaper holder 3 directly below the laser drilling device 52 is completed, the driving member 55 is reset, the diaper holder 3 is reset under the action of the first reset member 38, the rotating rod 62 is reset under the action of the second reset member 66, and the suction cover 81 is reset under the action of the third reset member 83. Then the conveying platform 2 works again to continue conveying the diaper holder 3. According to the above steps, the continuous processing and production of diapers is completed.

[0059] The breathable baby diaper produced according to the production device achieves an all-round ventilation effect through the ventilation holes 121 provided at the waist circumference 12, reducing discomfort to the baby's skin. The elastic elastic band 122 is provided to adapt to the body shape and waist circumference of different babies, while ensuring tightness and stability of wearing. The elastic airbag 13 is provided. When the baby turns over or moves, the elastic airbag 13 is squeezed. The contraction of the elastic airbag 13 causes the gas in the elastic airbag 13 to be ejected from the exhaust hole 131. The gas flows through the ventilation groove 111 of the absorbent body 11 and enters the space wrapped around the baby's buttocks, thereby improving air circulation and breathability. Urine that is not absorbed by the absorbent body 11 in time will flow into the liquid holding cavity 132 and into the elastic airbag 13 through the liquid inlet hole 133 for storage. The waterproof and breathable membrane provided in the exhaust hole 131 and the one-way water-permeable membrane provided in the liquid inlet hole 133 prevent the urine in the elastic airbag 13 from leaking, thereby improving the urine absorption effect.

[0060] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
