Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1 to 5 shown, the present utility model provides a sanitary napkin pressing and forming device, including a transmission plate 1. A support frame 2 is fixedly connected to the outside of the transmission plate 1. A first rotating shaft 3 is rotatably connected inside the support frame 2. An embossing roller 4 is sleeved on the outside of the first rotating shaft 3. A moving ring 6 is tightly pressed against the outside of the embossing roller 4. An extension block 5 is fixedly connected to the support of the support frame 2. The first gear 19 sleeved on the outside of the second rotating shaft 21 drives the transmission rod 22 fitted inside the second gear 20 to rotate. The transmission rod 22 drives the convex block 12 welded and fixed thereto to rotate inside the fixing plate 11. The convex block 12 pats the sliding plate 10 to slide downward. The hole puncher 15 sliding inside the sliding plate 10 squeezes the sanitary napkin body 9 to punch holes in it.

[0024] Specifically, after the hole punching is completed, the spring 14 cooperates with the telescopic rod 13 to drive the sliding plate 10 at the top to return to its original position.

[0025] Further, the bottom end of the hole puncher 15 is slidably connected to a sleeve 16.

[0026] Still further, the hole puncher 15 sliding inside the sliding plate 10 squeezes the sanitary napkin body 9 to punch holes in it. The sleeve 16 is fitted inside the circular hole groove at the top of the transmission plate 1. The bottom end of the sanitary napkin body 9 is attached to the top of the transmission plate 1.

[0027] It should be noted that the convex block 12 rotates inside the fixed plate 11, and the convex block 12 pats the sliding plate 10 to slide downward.

[0028] It is worth noting that when the sanitary napkin body 9 slides to the bottom end of the knotting and squeezing roller 18 sleeved outside the second rotating shaft 21, the rotating squeezing roller 18 separates the sanitary napkin body 9 from the scraps 8.

[0029] It is worth introducing that the outer side of the collecting roller 7 is rotatably connected to the scraps 8, and the scraps 8 are wound around the outer side of the collecting roller 7.

[0030] Among them, the sanitary napkin body 9 is a prior art and will not be elaborated here; at the same time, the present utility model also includes a power source, a controller, a switch, etc., which are not the main technical points of this patent and will not be elaborated here; the "front, back, left, and right" perspectives of this device are based on Figure 1 the direction shown in the figure.

[0031] Working principle:

[0032] First, the staff places the scraps 8 and the sanitary napkin body 9 on the top of the transfer plate 1 and slides them to the left. The first rotating shaft 3 inside the support frame 2 drives the embossing roller 4 inside to rotate, embossing the top surface of the sanitary napkin body 9 to make a beautiful shape and pressing it tightly between the internal materials of the sanitary napkin body 9. When the sanitary napkin body 9 slides to the bottom end of the squeezing roller 18, the rotating squeezing roller 18 separates the sanitary napkin body 9 from the scraps 8, and cooperates with the collecting roller 7 rotating inside the lengthening rod 17 at the top of the extension block 5 to wind and collect the separated scraps 8. After peeling, it then slides to the left.

[0033] When it slides to the bottom end of the sliding plate 10, the first gear 19 sleeved outside the second rotating shaft 21 drives the transmission rod 22 engaged inside the second gear 20 to rotate. The transmission rod 22 drives the convex block 12 welded and fixed to it to rotate inside the fixed plate 11. The convex block 12 pats the sliding plate 10 to slide downward. The punch 15 sliding inside the sliding plate 10 squeezes the sanitary napkin body 9 to punch it. After punching, the spring 14 cooperates with the telescopic rod 13 to drive the sliding plate 10 at the top to return to its original position. After stamping and punching, the sanitary napkin body 9 slides from the top of the transfer plate 1 to the left into the collecting box.

[0034] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
