Description

Technical Field

[0002] Rare earth composite antibacterial sanitary napkins are a product that is made by compounding rare earth elements with other antibacterial materials, adding them to the material of the sanitary napkin, and using their antibacterial properties to improve the hygiene performance and user experience of the sanitary napkins. Rare earth elements, as a metal element with special properties, are usually used to improve the antibacterial and antioxidant properties of materials and extend the service life of products. Sanitary napkins are prone to produce odors due to bacterial growth during use. The antibacterial effect of rare earth composite materials helps reduce the growth of these bacteria, thereby delaying the generation of odors. During the production process of rare earth composite antibacterial sanitary napkins, the absorbent core, non-woven fabric and other materials need to be firmly bonded together through hot pressing to form a stable overall structure.

[0021] 2. By setting up a brush mechanism, the second motor drives the sleeve shaft and the second rotating shaft to rotate through gears, so that the surface of the material is brushed by the brush roller, and when the second rotating shaft rotates, it drives the arc-shaped drive ring to rotate synchronously, and under the action of the second spring, drives the second rotating shaft to swing left and right in the inner cavity of the sleeve shaft, driving the brush roller to move synchronously, thereby improving the brushing effect. In addition, when the upper and lower sides of the die contact to hot-press the sanitary napkin, the die is squeezed and moved toward the inner cavity of the turntable, injecting the air in the air collecting cavity into the hollow part of the first rotating shaft, and sending it into the hollow part of the brush roller by the second rotary joint and the first rotary joint, and finally sprayed out to the surface of the material from the nozzle, thereby increasing the fluffiness of the material, making the heat distribution more uniform during the hot pressing process, and improving the bonding effect.

[0022] 3. By setting up a feeding mechanism, whenever the upper and lower dies come into contact, the first rotating shaft drives the third rotating shaft to rotate one circle through the pulley, so that the third through hole is connected to the driving groove, and the driving groove is injected with air through the air pump. Since the aperture of the third through hole is larger than the air hole, part of the air flow pushes the second connecting rod downward, and the sanitary napkin is separated from the material through the push block for feeding, and the other part of the air flow is sprayed onto the surface of the sanitary napkin through the air hole, which performs secondary heat dissipation on the sanitary napkin to ensure the quality of the sanitary napkin.

[0037] Reference Figure 1-Figure 5 As shown, in a preferred embodiment, the first connecting rod 407 is symmetrically fixedly installed at the bottom of the mold 403, the first connecting rod 407 is slidably connected to the turntable 401, and the surface of the first connecting rod 407 is sleeved with a first spring 408, which is used to drive the mold 403 to move toward the outside of the turntable 401. The air collecting chamber 409 is opened in the inner cavity of the turntable 401, and the first piston 410 is slidably installed in the air collecting chamber 409. The first piston 410 is fixedly connected to one end of the first connecting rod 407. When the molds 403 on the upper and lower sides contact to heat-press the sanitary napkin, the mold 403 is squeezed and moved toward the inner cavity of the turntable 401, driving the first connecting rod 407 and the first piston 410 to move synchronously.

[0048] Specifically, the working principle of the rare earth composite antibacterial sanitary napkin hot stamping device is as follows: when in use, the turntables 401 on the upper and lower sides can be driven to rotate in opposite directions at a constant speed by the first motor 415. When the pressing dies 403 on the upper and lower sides contact to hot-press the sanitary napkin, the pressing dies 403 are squeezed and move toward the inner cavity of the turntable 401, driving the first connecting rod 407 and the first piston 410 to move synchronously. Under the action of the first piston 410, the air collecting cavity 409 on the side of the first limiting ring 411 is sucked, and the negative pressure hole 414 is sucked through the first air channel 413, thereby During pressing, the sanitary napkin material is adsorbed on the surface of the pressing mold 403 to prevent the sanitary napkin material from slipping with the first hot pressing strip 404 and the second hot pressing strip 405, thereby ensuring the quality of hot pressing; when the hot pressing is completed and the pressing molds 403 on both sides are separated from each other, the first spring 408 pushes the first piston 410 to reset, and the air in the air collecting chamber 409 is ejected from the negative pressure hole 414 again to dissipate the heat of the sanitary napkin after hot pressing. At the same time, the sanitary napkin is blown away from the first hot pressing strip 404 and the second hot pressing strip 405 to prevent the sanitary napkin from sticking to the first hot pressing strip 404 and the second hot pressing strip 405.

[0049] The second motor 507 drives the sleeve shaft 501 and the second rotating shaft 502 to rotate through gears, thereby brushing the surface of the material through the brush roller 505, and when the second rotating shaft 502 rotates, it drives the arc drive ring 512 to rotate synchronously, and under the action of the second spring 511, it can drive the second rotating shaft 502 to swing left and right in the inner cavity of the sleeve shaft 501, driving the brush roller 505 to move synchronously, thereby improving the brushing effect. In addition, when the upper and lower sides of the die 403 contact to perform hot pressing on the sanitary napkin, the die 403 is squeezed and moved toward the inner cavity of the turntable 401, injecting the air in the air collecting chamber 409 into the hollow part of the first rotating shaft 402, and sending it into the hollow part of the brush roller 505 by the second rotary joint 515 and the first rotary joint 514, and finally sprayed onto the surface of the material through the nozzle 519, thereby increasing the fluffiness of the material, making the heat distribution more uniform during the hot pressing process, and improving the bonding effect.

[0050] Whenever the upper and lower dies 403 come into contact, the first rotating shaft 402 drives the third rotating shaft 609 to rotate one circle through the pulley, so that the third through hole 610 is connected to the driving groove 604, and the driving groove 604 is injected with air through the air pump 614. Since the aperture of the third through hole 610 is larger than the air hole 611, part of the air flow pushes the second connecting rod 606 downward, and the sanitary napkin is separated from the material through the push block 607 for unloading. The other part of the air flow is sprayed onto the surface of the sanitary napkin through the air hole 611, and the sanitary napkin is cooled for a second time to ensure the quality of the sanitary napkin.

[0051] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
