Description

Technical Field

[0001] The present invention relates to the technical field of night-use sanitary napkin production equipment, and particularly discloses a night-use sanitary napkin and its production equipment. Background Art

[0002] A night-use sanitary napkin is a special sanitary product designed to provide protection for women during menstruation, especially for use at night to ensure comfort and safety over a long period. Compared with daily-use sanitary napkins, night-use sanitary napkins usually have greater absorption capacity and a longer design to address the risk of leakage caused by nighttime activities and changes in sleeping positions. The main function of a night-use sanitary napkin is to absorb menstrual flow, prevent leakage, and keep the user dry and comfortable. Night-use sanitary napkins are usually longer than daily-use sanitary napkins to increase the coverage area and reduce the risk of nighttime leakage. This design factor takes into account the possible different postures of women during sleep. With the growing demand for night-use sanitary napkins among female consumers, the market has put forward higher requirements for products with high quality, comfort, and strong absorption capacity. At the same time, the market for night-use sanitary napkins also faces some challenges: In summary, as an important part of female hygiene care products, with the continuous progress of technology, the design and production equipment of night-use sanitary napkins are also evolving continuously to meet market demands and consumer expectations.

[0003] The patent with the publication number CN118662302A discloses a night-use soft-skin sanitary napkin and its production equipment. The technical solution of this patent is as follows: It includes a body, and the body includes a front area, a middle area, and a rear area that are sequentially connected from front to back in the transverse direction; two butterfly tails are provided in the rear area of the body at intervals left and right, and a deformation part with a "V" shape that is narrow in the front and wide in the rear is formed between the adjacent inner sides of the two butterfly tails. An extension body extending inward is provided on the side of the butterfly tail close to the deformation part; the thickness of the absorbent layer in the area of the deformation part is less than the thickness of the absorbent layer in the area of the butterfly tail; when the body fits the human body contour in the wearing state, the deformation part can form a concave fish fin body that fits the contour of the buttock groove, and the extension body can form a shaping support structure for the fish fin body and a blocking structure to prevent menstrual blood from flowing backward and leaking, but the production equipment of this patent lacks the limitation of the sanitary napkin to be processed during processing, thus easily generating processing errors. Therefore, a night-use sanitary napkin and its production equipment are invented to address this defect. Summary of the Invention

[0035] The working principle of the present invention is as follows.

[0036] (1) The first motor 201 is started. The first motor 201 drives the first connecting shaft 214 to move through the turntable 213. The first connecting shaft 214 drives the second connecting shaft 216 to move through the first connecting rod 215. The second connecting shaft 216 drives the first gear 218 to rotate. The first gear 218 drives the rotating plate 203 to rotate through the second transmission shaft 217. The rotating plate 203 drives the lower frame 205 and the upper clamp 206 to rotate through the sliding shaft 207. When the rotating plate 203 is turned 90 degrees, the sanitary napkin to be processed is placed manually between the lower frame 205 and the upper clamp 206. At the same time, the first gear 218 drives the first rack 219 to rotate. The first rack 219 rotates through the third gear 223. The third gear 223 drives the second driving rod 227 to rotate through the fourth connecting shaft 225, so that the second driving rod 227 contacts the first contact switch 228, and thus the electromagnet is energized to make the lower frame 205 and the upper clamp 206 approach each other to complete the clamping of the sanitary napkin. Then the first motor 201 rotates in the reverse direction. When the rotating plate 203 returns to its original position, the first upper block 222 contacts the second contact switch 229, thus completing the power-off of the electromagnet. Then the lower frame 205 and the upper clamp 206 move away from each other, thus loosening the sanitary napkin.

[0037] When the first upper block 222 contacts the second contact switch 229, the first electric cylinder 313 is activated. The first electric cylinder 313 drives the right-angle rod 309 to move through the first moving block 314. The right-angle rod 309 drives the fourth gear 306 to move through the moving frame 307, and drives the fourth gear 306 to rotate through the second rack 305. The fourth gear 306 drives the fifth connecting shaft 315 to move through the second connecting rod 308. The fifth connecting shaft 315 drives the ejector rod 312 to move through the intermediate block 311, thereby pushing and flipping the sanitary napkin towards the middle. At the same time, the second electric cylinder 412 is activated, and the slider 408 is driven to slide along the first mounting shaft 407 through the second electric cylinder 412. The slider 408 drives the third connecting rod 409 to move. The third connecting rod 409 drives the push shaft 411 to move through the driving block 410. When the fourth gear 306 disengages from the second rack 305, the push shaft 411 is inserted into the positioning hole 310, thereby completing the positioning of the second connecting rod 308.

[0038] At this time, the heating circuit in the heating clamp 506 is activated, and the third electric cylinder 502 is activated. The third electric cylinder 502 drives the connecting rod 503 to descend. The connecting rod 503 drives the mounting bracket 505 to descend through the second mounting rod 504. At the same time, the second motor 508 is activated. The second motor 508 drives the heating clamps 506 to approach each other through the screw rod 507, thereby thermally pressing the overlapping part of the sanitary napkin through the heating clamps 506. After the thermal pressing is completed, the sanitary napkin is taken off.

[0039] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to embrace all changes that fall within the meaning and scope of the equivalent elements of the claims in the present invention. Any reference signs in the claims should not be regarded as limiting the claims involved.
