[0002] Nursing pads are disposable sanitary products made of PE film, non-woven fabrics, fluff pulp, polymers and other materials. They are mainly used in hospital surgery, gynecological examinations, maternal care, child care, paralyzed patients with incontinence, and women during menstruation. According to different user groups, nursing pads can be divided into baby nursing pads, maternal nursing pads, and adult nursing pads. Baby nursing pads are mainly used for newborns to isolate urine to ensure that the mattress or mattress below is not soaked by urine. Therefore, baby nursing pads are also called urine-isolating pads. When the baby nursing pad is wet, it is best to replace it immediately to ensure that the baby's buttocks are dry. Maternal nursing pads are mainly essential items for women after childbirth, also known as puerperal pads. After giving birth, a large amount of lochia will flow out every day in the first half of the month, and ordinary sanitary napkins cannot meet them. At this time, special maternal nursing pads are needed. The use time of maternal nursing pads is generally from the first time after delivery to the entire puerperal period when bleeding and lochia are discharged. Adult nursing pads are mainly used for people after surgery, paralyzed people, and people who cannot take care of themselves. The adult nursing pad is easy to replace and will not stain the mattress underneath.

If the waterproof diaper pad is thinner, the threaded rod 597 is rotated clockwise to make the L-shaped rod 595 press the limit rod 592 upward or downward;

[0054] Step 3: When the limiting rod 592 moves up and down, the first cylinder 56 and the second cylinder 58 will change their angles, so that the support frame 73 drives the straightening plate 78 to move closer or farther away;

[0055] Step 4: After adjusting the distance between the straightening plates 78, connect the heater 92 to the power supply and turn on the switch of the heater 92. After the heater 92 starts working, the heater frame 93 is heated and the temperature of the iron frame 95 is increased;

The sewing device for a waterproof diaper pad according to claim 2, characterized in that: The suturing device (9) comprises a block (91), the block (91) being fixedly connected to the top end of the connecting frame (8), the outer surface of the block (91) being fixedly connected to a heating machine (92), the output end of the heating machine (92) being fixedly connected to a heating frame (93), the upper surface of the heating frame (93) being fixedly connected to a fixing rod (94), and the top end of the fixing rod (94) being fixedly connected to an iron frame (95).

4. The sewing device for waterproof diaper pad according to claim 1, characterized in that: Use the following steps: Step 1: Before sewing the sides of the waterproof diaper pad, first cut a small section of the waterproof diaper pad, and then place the cut small section of the sample in the inner cavity of the iron frame (95), and at this time, the heating machine (92) does not need to start working; Step 2: After the sample is placed, the threaded rod (597) is rotated. If the waterproof urine pad is thicker, the threaded rod (597) is rotated counterclockwise. If the waterproof urine pad is thinner, the threaded rod (597) is rotated clockwise, so that the L-shaped rod (595) presses the limit rod (592) upward or downward; Step 3: When the limiting rod (592) moves up and down, the first cylinder (56) and the second cylinder (58) will change their angles, thereby causing the support frame (73) to drive the straightening plate (78) to move closer or farther away; Step 4: After adjusting the distance between the straightening plates (78), the heating machine (92) is connected to a power source and the switch of the heating machine (92) is turned on. After the heating machine (92) starts to work, the heating frame (93) is heated and the temperature of the iron frame (95) is increased; Step 5: After the temperature of the iron frame (95) rises, the operator inserts the end of the waterproof diaper pad into the inner cavity of the iron frame (95) and continuously moves the waterproof diaper pad. During the movement, the plastic on the side of the waterproof diaper pad is melted by the iron frame (95), so that the side of the waterproof diaper pad is bonded together, thereby completing the sewing work of the side of the waterproof diaper pad.
