[0002] Explosive beads, also known as fragrant pills, brittle capsules, and beads, are squeezeable beads that have a bursting feeling when squeezed. In the prior art, explosive beads are generally used in cigarettes. Non-woven fabrics are now used in more and more products in the field of women's health, such as facial masks, sanitary napkins, makeup remover cotton, wet wipes, etc. The disposable sanitary products market has basically become saturated. With the upgrading of consumption, the main driving force for disposable sanitary products in the future will be the high-end, differentiated, and personalized products. Plant essential oils and herbal extracts currently have significant effects in anti-anxiety, skin care, and antibacterial and antibacterial effects. Plant essential oils and natural herbal extracts have a large market for relieving negative emotions during women's menstrual period, and there are many applications on the market, that is, spraying plant essential oils or natural herbal extracts on the liquid-permeable surface layer or absorbent core layer of disposable sanitary products during the sanitary preparation process, but essential oils and extracts are easy to volatilize, so that a large amount of loss will occur during packaging or use, and the use effect is not ideal. In addition, disposable sanitary products sprayed with essential oils or extracts need to be packaged in single pieces to maximize the use effect, which increases the processing cost; therefore, the combination of bursting bead technology with essential oils or extracts and their application in disposable sanitary products is an innovation and can provide a new idea for our company to create a natural, high-end and differentiated image for its products.

[0032] like Fig.17 As shown, a transmission rubber roller 4 is further provided behind the secondary rolling mechanism 4 , and a groove 41 for preventing the beads from extruding is opened in the middle of the transmission rubber roller 4 along the circumferential direction.

[0033] For the production process of combining bursting beads with non-woven fabrics, the characteristics and parameters of the transmission rubber roller need special attention. First of all, the material of the rubber roller should have a certain degree of softness and elasticity to reduce the squeezing of the bursting beads. For example, you can choose a high-quality rubber material that can provide moderate buffering during the transmission process and reduce the risk of squeezing the bursting beads. You can also wrap a sponge layer on the transmission rubber roller. Secondly, the surface roughness of the rubber roller is also critical. A surface that is too rough may increase the friction between the material and exert greater pressure on the bursting beads. Therefore, you should choose a rubber roller with a smooth surface, or perform surface treatment on the rubber roller, such as grinding and polishing, to reduce the surface roughness.

[0034] 2. Material selection and improvement Choose the right material for the beads Consider the size and shape of the beads. Smaller beads are more susceptible to compression. You can increase the size of the beads appropriately, or choose a more regular shape with stronger compression resistance, such as a spherical or elliptical shape. The size of the beads is between 2mm-10mm Optimizing nonwoven properties Choose non-woven fabrics with soft texture and good elasticity. Such non-woven fabrics can better adapt to the shape of the bursting beads when combined with the bursting beads and reduce local pressure concentration. The material screening and performance testing of non-woven fabrics can be carried out to ensure that they meet production requirements.

[0035] Fluffy nonwoven fabric is a material with unique properties, and it also has an important influence in the production of the combination of burst beads and nonwoven fabrics.

[0036] 1. Structural characteristics 1. Loose fibers The internal fiber structure is relatively loose and filled with a large number of air gaps. This structure makes the non-woven fabric soft and elastic, which can buffer the external pressure to a certain extent and reduce the squeezing of the beads. When in contact with the beads, the fluffy fibers can adapt to the shape of the beads, disperse the pressure, and reduce the risk of squeezing.

[0037] The air gap also gives the fluffy nonwoven good thermal and sound insulation properties. In some production environments, this may help maintain stable temperature and humidity, reducing the impact of external factors on the bead and nonwoven bonding process.

[0038] 2. Thickness is relatively large Compared with ordinary non-woven fabrics, fluffy non-woven fabrics are usually thicker. This increases the material's cushioning capacity and provides more protection for the bursting beads. During the high-speed production process of the roller, the thicker non-woven fabric can absorb more impact and reduce the pressure on the bursting beads. The greater thickness also makes the fluffy non-woven fabric more three-dimensional in appearance, giving the product a better texture and touch.

[0039] 2. Performance Advantages 1. Good breathability Fluffy nonwoven fabrics have good air permeability and allow air to circulate freely. This is very important for the combination of popping beads and nonwoven fabrics, because good air permeability can prevent moisture accumulation and keep the popping beads dry and stable. At the same time, breathable nonwoven fabrics also help to dissipate heat during the production process to avoid damage to the popping beads caused by excessive local temperatures.

[0040] High breathability also makes the product more comfortable during use and will not cause stuffiness.

[0041] 2. Moderate hygroscopicity Although fluffy nonwoven fabrics have a certain degree of hygroscopicity, they usually do not absorb excessive moisture. This is very beneficial for the preservation of the beads, because too much moisture may cause the beads to rupture or lose their activity. Moderate hygroscopicity can absorb the small amount of moisture that may be generated during the production process without affecting the performance of the beads. In some special application scenarios, such as when the beads need to be moisturized, the fluffy nonwoven fabric can be specially treated to adjust its hygroscopicity to meet specific needs.

[0042] Nonwoven fabrics include: all nonwoven fabrics The amount of popping beads added is: 1-100 The thickness of fluffy non-woven fabric is: 5-50mm, and the weight is 10-60gsm The weight of the upper non-woven fabric is: 5-25gsm like Fig.18 As shown, the longitudinal positioning glue spraying mechanism 2 includes a fixing bar 21, the bottom of which is provided with a first glue gun 22 which cooperates with the bead-blasting fixing roller 32, and the transverse glue spraying mechanism 20 includes a slide rail 202, and a second glue gun 203 is provided in the sliding direction of the slide rail.

[0043] Working principle: Figure 1-19As shown, when a row of bursting beads is added, the controller controls the rotation of the partition motor 435, thereby driving the rotation of the first gear 434, thereby driving the rotation of the first rack 433, thereby driving the partition plate 432 to move downward, so that the partition plate 432 is stuck in the through groove, and at the same time, the controller controls the rotation motor 330 to rotate, thereby driving the rotation motor 330 of the radial telescopic mechanism 33 to drive one of the second gears 334 to rotate, thereby driving the internal gear 335 to rotate, thereby driving the second rack 333 to move outward in the radial direction until the top of the plug core 325 extends out to the notch of the bursting bead accommodating cavity 320, and cooperates with the annular gap filling silicone plate to form a rolling surface that is the same as the rolling area. The controller controls the motor as a very mature technology, so it will not be repeated in this case. After that, the bursting beads 403 are dropped into the limiting cover 43 through the feeding pipe 42 through the storage hopper 41, and are limited in the area between the two partition plates 432 by the partition plate 432. The feeding roller 44 rotates and passes through the limiting cover 43 Excess explosive beads 403 are scraped off, and only the explosive beads 403 that fall into the explosive bead discharge groove 441 are passed through. When the explosive bead discharge groove 441 rotates to the bottom, they fall onto the fluffy non-woven fabric 401, so that the explosive beads 403 are continuously and evenly scattered on the fluffy non-woven fabric 401 at the bottom. At the same time, the upper non-woven fabric 402 is sprayed with glue on the upper surface through the longitudinal glue spraying mechanism 2 and the transverse glue spraying mechanism 20, and the position corresponding to the explosive beads is not sprayed with glue. After spraying, it is turned over to cover the fluffy non-woven fabric layer containing the explosive beads. The bottom fluffy non-woven fabric 401 and the upper non-woven fabric 402 containing bursting beads are rolled once by a primary rolling mechanism 3 to seal the bursting beads between the bottom fluffy non-woven fabric layer and the upper non-woven fabric to form a composite non-woven fabric containing bursting beads. The composite non-woven fabric with the bursting beads 403 sealed is rolled for a second time by a secondary rolling mechanism 4 to obtain a composite non-woven fabric with a plurality of essential oil bursting beads arrayed therein, which can be used in different fields such as towels, makeup remover cotton pads, wet wipes, facial masks, etc., thereby providing high-end products.

[0044] In order to meet the needs of users, if more columns of bursting beads are needed, it is only necessary to control the rotation of the partition motor 435 through the controller, thereby driving the rotation of the first gear 434, thereby driving the rotation of the first rack 433, thereby driving the partition plate 432 to move upward, thereby increasing the range of the bursting beads 403 after falling into the limiting cover 43. At the same time, the controller controls the rotation motor 330 to rotate, thereby driving the rotation motor 330 of the radial telescopic mechanism 33 to drive one of the second gears 334 to rotate, thereby driving the internal gear 335 to rotate, thereby driving the second rack 333 to move inward along the radial direction until the plug core 325 is retracted into the through hole, forming a groove, forming a bursting bead avoidance area, when the bursting bead avoidance area 432 is converted into a rolling area, the first glue gun of the upper non-woven fabric sprays glue, when it is a bursting bead avoidance area, the first glue gun does not spray glue, so that it can cooperate with the partition plate, so that the user can choose to add the number of columns of bursting beads.
