Description

Technical Field

[0001] The present invention relates to the field of composite knitted fabrics, and particularly to a preparation process of a composite knitted fabric containing explosion beads. Background Art

[0002] With the improvement of people's living standards and the enhancement of health awareness, functional textiles have received increasing attention. Functions such as antibacterial, aromatic, and moisturizing have become important considerations for consumers when choosing textiles. These functional textiles can bring more convenience and comfort to people's lives, and at the same time help improve people's quality of life. However, there are still certain deficiencies in the durability, stability, and diversity of functions of functional textiles currently on the market.

[0003] As a new technical means, explosion beads have shown great application potential in other fields. Explosion beads have a unique structure, which can encapsulate functional substances and release them through specific triggering methods to achieve specific functions. Introducing the explosion bead technology into the production of composite knitted fabrics is expected to endow textiles with new functional characteristics and meet the diverse needs of consumers for functional textiles.

[0004] Although the current composite knitted fabrics combine the advantages of different materials to a certain extent, they still lack in terms of function integration and innovation. For example, existing composite knitted fabrics often have difficulty achieving multiple functions simultaneously, and the addition methods of functional substances are relatively single, resulting in unsatisfactory durability and stability of functions. In addition, existing production processes also have problems such as low production efficiency and high costs, which limit the large-scale application and promotion of composite knitted fabrics.

[0005] With the continuous improvement of people's living standards, the requirements for the functionality and comfort of textiles are also getting higher and higher. Composite knitted fabrics have been widely used in the fields of clothing, home furnishings, etc. due to their good elasticity, breathability, and comfort. However, the existing composite knitted fabrics still have certain limitations in terms of functions and cannot meet people's needs for special functions. As a new type of functional material, explosion beads have unique structures and properties. Applying explosion beads to composite knitted fabrics can endow the knitted fabrics with more functions, such as antibacterial, aromatic, and moisturizing. Therefore, a preparation process of a composite knitted fabric containing explosion beads needs to be proposed. Summary of the Invention

[0006] The purpose of the present invention is to solve the problems in the background art and provide a preparation process of a composite knitted fabric containing explosion beads.

[0007] The above technical purpose of the present invention is achieved through the following technical solutions: A preparation process for a composite knitted fabric containing bursting beads, comprising the following steps: S1, Softening and drying: The upper knitted fabric is softened through a softening impregnation device 9 and then dried; S2, Continuously applying bursting beads: The bursting beads are positioned and quantitatively discharged through the positioning and quantitative discharging mechanism 1 of the bursting bead adding device 1, and the bursting beads are continuously sprinkled on the high-loft hot air non-woven fabric at the bottom to form more than three continuous bursting bead layers; S3, Glue spraying and flipping: The upper knitted fabric is subjected to positioning glue spraying through the positioning glue spraying mechanism 2, and no glue is sprayed at the position corresponding to the bursting beads. After glue spraying, it is flipped and covered on the high-loft hot air non-woven fabric containing bursting beads; S4, Sealing the bursting beads: The high-loft hot air non-woven fabric and the knitted fabric containing bursting beads are heated and rolled through the rolling mechanism 3 to seal the bursting beads between the bottom high-loft hot air non-woven fabric and the knitted fabric, forming a composite knitted fabric; S5, Drying and curing: The composite knitted fabric with bursting beads sealed is dried and cured.

[0008] In the present invention, the upper knitted fabric is softened through a softening impregnation device and then dried, which can reduce static electricity and make it softer. Then, the bursting beads are continuously sprinkled in the middle of the high-loft hot air non-woven fabric. Then, glue is sprayed on the upper surface of the upper knitted fabric, and no glue is sprayed at the position opposite to the bursting beads, so that there is no hot-melt adhesive at the position of the bursting beads, preventing the problem that the bursting beads cannot be pinched due to being wrapped by the hot-melt adhesive in the later stage. Then, it is flipped so that the upper surface of the upper knitted fabric turns downward, and together with the high-loft hot air non-woven fabric with bursting beads sprinkled, it is longitudinally rolled through the rolling mechanism to seal the bursting beads between the bottom high-loft hot air non-woven fabric layer and the upper knitted fabric, forming a composite knitted fabric containing bursting beads. Then, it is dried and cured, thereby obtaining a composite knitted fabric containing bursting beads, endowing the knitted fabric with more functions, such as antibacterial, aromatic, moisturizing, etc., which can meet people's needs for functional textiles. The combination of the bursting beads and the knitted fabric is firm, not easy to fall off, and has a long service life.

[0009] I. Upper knitted fabric It is usually made of natural fibers (such as cotton, linen, silk, etc.) or synthetic fibers (such as polyester, nylon, spandex, etc.). These fibers have good elasticity, air permeability and moisture absorption, and can provide a comfortable experience for the wearer. The knitting structure of the knitted fabric gives it a soft hand feeling and good ductility, and can adapt to the movement and changes of the body.

[0010] As the outer layer of the bursting bead knitted fabric, the upper knitted fabric plays a role in protecting the bursting beads and providing a comfortable touch. It can prevent the bursting beads from being rubbed and damaged by the outside world, and at the same time provides a soft contact surface for the wearer.

[0011] The upper knitted fabric can also be dyed, printed, etc. according to needs to enhance its aesthetics and fashion sense.

[0012] II. Lower high-bulk hot air nonwoven fabric High-bulk hot air nonwoven fabric is usually made of synthetic fibers such as polypropylene and polyester. It has high bulkiness, softness and breathability, and can provide good support and protection for the bursting beads.

[0013] The production process of the hot air nonwoven fabric gives it a uniform fiber distribution and good strength, enabling it to withstand certain pressure and tensile force.

[0014] As the inner layer of the bursting bead knitted fabric, the lower high-bulk hot air nonwoven fabric plays the role of carrying the bursting beads and maintaining the stability of the bursting beads. Its high bulkiness can provide enough space for the bursting beads to prevent the bursting beads from being squeezed and broken during use.

[0015] The breathability of the hot air nonwoven fabric allows the functional substances in the bursting beads to be released smoothly and play their due roles. At the same time, it can also prevent the substances in the bursting beads from penetrating into the external environment and maintain the sealing and stability of the bursting beads.

[0016] III. Distribution and function of the bursting beads between the two layers Distribution method The bursting beads are usually evenly distributed between the upper knitted fabric and the lower high-bulk hot air nonwoven fabric. Through special production processes such as spraying and impregnation, the bursting beads can be fixed between the two layers to ensure the stability and uniformity of the bursting beads.

[0017] Function and role The bursting beads contain various functional substances such as antibacterial agents, fragrances, and moisturizers. When subjected to external force extrusion or friction, the bursting beads will break and release the functional substances therein, providing corresponding functions for the wearer.

[0018] The presence of the bursting beads can endow the knitted fabric with more functions and characteristics to meet the needs of different consumers. For example, antibacterial bursting beads can provide antibacterial protection for the wearer, fragrant bursting beads can bring a pleasant aroma to the wearer, and moisturizing bursting beads can provide a moisturizing effect for the wearer's skin.

[0019] The bead adding device includes a machine frame, on which a positioning and quantitative discharging mechanism and a rolling mechanism are sequentially arranged in the direction from left to right. Above the rolling mechanism, a longitudinal positioning glue spraying mechanism and a transverse glue spraying mechanism are provided. The longitudinal positioning glue spraying mechanism and the transverse glue spraying mechanism are arranged in parallel. Below the longitudinal positioning glue spraying mechanism and the transverse glue spraying mechanism, two parallel first guide rollers are provided. On the left side of the primary rolling mechanism, a second guide roller for flipping the upper-layer knitted fabric is provided. The whole device adopts automation, reduces labor, improves production efficiency, ensures hygiene, and is suitable for large-scale production.

[0020] The positioning and quantitative discharging mechanism includes a storage hopper, a feeding pipe, a material limiting cover, and a feeding roller that are sequentially arranged on the machine frame from top to bottom. The feeding pipe is arranged between two through grooves. The inside of the material limiting cover is a cavity. An arc-shaped limiting opening for facilitating the rotation of the feeding roller is formed on one side of the material limiting cover close to the feeding roller. The gap between the arc-shaped limiting opening and the feeding roller is smaller than the outer dimension of the material. A plurality of bead discharging grooves are formed on the roller surface of the feeding roller along the circumferential direction. There are three or more groups of bead discharging grooves arrayed along the axial direction of the feeding roller. The area formed between two adjacent partition plates corresponds to a group of bead discharging grooves. When the partition plates are not in use, they are placed at a designated position for easy taking.

[0021] The material limiting cover of the present invention is used to prevent the material from falling onto the non-woven fabric and the feeding roller before being transported. The beads are dropped from the storage hopper through the feeding pipe onto the top surface of the feeding roller, and the excess beads are scraped off by the material limiting cover. Only the beads that fall into the bead discharging grooves are used, so as to continuously and evenly scatter the beads onto the high-loft hot air non-woven fabric, realizing the step of continuously applying beads.

[0022] Two or more through grooves are formed on the top of the material limiting cover along the length direction. Above the through grooves, there is a partition plate that can be inserted into the through grooves. Limiting pieces are fixed on both sides of the top of the partition plate. When separation is needed, the partition plate is inserted into the through grooves, and the limiting pieces are located above the through grooves, thus realizing a detachable partition plate.

[0023] By inserting the partition plate into the material limiting cover of the present invention, the number of columns of beads added can be selected according to requirements, increasing the applicability of the device.

[0024] Preferably, the rolling mechanism includes a heating roller and a bead fixing roller rotatably arranged on the frame. The bead fixing roller is arranged above the heating roller. The bead fixing roller includes a hollow roller body. A rotating shaft is fixed in the middle of the roller body. The rotating shaft is fixedly connected with the inner side of the roller body through a support bar. The roller body can be divided into a front rolling area, a bead avoidance area, and a rear rolling area along the axial direction. An annular groove is formed on the surface of the bead avoidance area along the circumferential direction. There are more than three annular grooves arranged in an array along the axial direction. A number of transverse rolling plates are evenly arranged in an array on the annular groove. The transverse rolling plates and the roller body form a bead accommodation cavity.

[0025] The heating roller can be heated by electric heating wires or heat-conducting oil, which is a mature technology and will not be elaborated in this case.

[0026] Through the cooperation of the front rolling area, the rear rolling area of the bead fixing roller and the bead accommodation cavity of the present invention, when the upper knitted fabric after spraying glue and the highly fluffy non-woven fabric added with beads are compounded, only the area without beads can be thermally roll-compounded. Since the annular groove is provided in the area with beads, the beads will not be squeezed. Thus, the beads are enclosed in the composite knitted fabric. At the same time, the transverse rolling plates can fix the beads in a square to prevent the beads from shifting.

[0027] Preferably, a number of through holes are formed at the bottom of the bead accommodation cavity. A plug core is arranged on each through hole. The inner sides of each group of plug cores arranged in the annular groove are connected with a radial expansion mechanism. The plug core moves radially in the bead accommodation cavity through the radial expansion mechanism. An annular gap filling silica gel plate is fixed at the notch of the bead accommodation cavity. The structure of the silica gel plate makes the material soft. When it serves as the bead avoidance area, the beads will not be squeezed.

[0028] The present invention controls the plug core to enter and exit the bead accommodation cavity through the radial expansion mechanism. When the top of the plug core extends out to the notch of the bead accommodation cavity, it cooperates with the annular gap filling silica gel plate to form a rolling surface the same as that of the rolling area. When the plug core is retracted into the through hole, a groove is formed to form a bead avoidance area. Thus, it can cooperate with the material separating plate to enable the user to select the number of columns of beads to be added.

[0029] Preferably, the radial telescopic mechanism includes an inner fixing ring, an outer fixing ring, a rack, a gear, and an internal gear. The rack is located above the internal gear. The outer fixing ring is arranged outside the inner fixing ring and is concentric with it. A gear placement space is formed between the outer fixing ring and the inner fixing ring. Radial chutes are opened in the radial direction between the outer fixing ring and the inner fixing ring. The number of the radial chutes is the same as the number of each group of plug cores on the annular groove. The rack is slidably arranged in the radial chute. The gear is arranged in the gear placement space and meshes with the rack. The internal gear is arranged inside the outer fixing ring and meshes with the gear. The internal gear and the outer fixing ring are rotationally connected through a bearing. Except for the gear connected to the rotary motor, other gears are rotationally connected to the side plate through a bearing. The plug core is fixed at the end of the gear. One of the gears is connected to a rotary motor. Side plates are fixed on both sides of the outer fixing ring, and the middle of the side plates is fixed on the rotating shaft.

[0030] In the present invention, one of the gears is driven to rotate by a rotary motor, thereby driving the internal gear to rotate, thereby driving the rack to perform a reciprocating motion along the radial direction, thereby controlling the plug core to enter and exit the bead accommodation cavity.

[0031] The longitudinal positioning glue spraying mechanism includes a fixing strip. A first glue gun that cooperates with the bead fixing roller is arranged at the bottom of the fixing strip. When the bead avoidance area is converted into a rolling area, the first glue gun of the upper knitted fabric sprays glue. When it is the bead avoidance area, the first glue gun does not spray glue, so that the glue spraying area of the first glue gun can be selected according to the number of columns where the beads are added.

[0032] The transverse glue spraying mechanism includes a slide rail. A second glue gun is arranged in the sliding direction of the slide rail. By sliding the second glue gun on the slide rail, transverse glue spraying can be performed while avoiding the places where beads need to be provided.

[0033] Preferably, the softening impregnation device includes an impregnation tank. A number of impregnation rollers arranged in an S shape are arranged in the impregnation tank, which can impregnate the knitted fabric multiple times to make it softer and more comfortable during later use. Three partition plates are arranged on the roller surface of the impregnation roller along the axial direction, and multiple knitted fabrics can be impregnated at one time, saving time.

[0034] In summary, the beneficial effects of the present invention are: 1. In the present invention, the upper knitted fabric is subjected to softening treatment through a softening impregnation device and then dried, which can reduce static electricity and make it more compliant. Then, the bursting beads are continuously sprinkled on the middle of the highly fluffy hot air non-woven fabric. After that, glue is sprayed on the upper surface of the upper knitted fabric, and no glue is sprayed at the position opposite to the bursting beads, so that there is no hot melt adhesive at the position of the bursting beads, preventing the bursting beads from being wrapped by the hot melt adhesive and unable to be pinched and broken in the later stage. Then, it is flipped so that the upper surface of the upper knitted fabric is turned downward, and together with the highly fluffy hot air non-woven fabric with bursting beads sprinkled on it, it passes through a rolling mechanism for longitudinal rolling, and the bursting beads are sealed between the bottom highly fluffy hot air non-woven fabric layer and the upper knitted fabric to form a composite knitted fabric containing bursting beads. Then, it is dried and cured, thereby obtaining a composite knitted fabric containing bursting beads, endowing the knitted fabric with more functions such as antibacterial, aromatic, and moisturizing, which can meet people's needs for functional textiles. The combination of the bursting beads and the knitted fabric is firm, not easy to fall off, and has a long service life; 2. Through the cooperation of the front rolling area, the rear rolling area of the bursting bead fixing roller and the bursting bead accommodating cavity in the present invention, when the upper knitted fabric after spraying glue and the highly fluffy non-woven fabric added with bursting beads are compounded, only the area without bursting beads can be subjected to hot rolling compounding. Since there are annular grooves at the places where the bursting beads are provided, the bursting beads will not be squeezed. Thus, the bursting beads are sealed in the composite knitted fabric. At the same time, a transverse rolling plate can fix the bursting beads in a square frame to prevent the bursting beads from shifting; 3. In the present invention, a radial telescopic mechanism is used to control the plug core to enter and exit the annular groove. When the top of the plug core extends to the notch of the annular groove, it cooperates with the silicone plate for filling the annular gap to form a rolling surface the same as that of the rolling area. When the plug core is retracted into the through hole, a groove is formed to form a bursting bead avoidance area, so that it can cooperate with the material separation plate, enabling the user to select the number of columns of bursting beads to be added; 4. The softening impregnation device of the present invention includes an impregnation tank, and a number of impregnation rollers arranged in an S shape are provided in the impregnation tank, which can impregnate the knitted fabric multiple times to ensure that it is more comfortable and soft during later use.

[0038] The following specific embodiments are only explanations of the present invention, and they do not limit the present invention. Those skilled in the art can make modifications without creative contributions to these embodiments after reading this specification, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.

[0039] The present invention will be described in detail below with reference to the accompanying drawings by way of examples.

[0040] Embodiment

[0041] As Figure 16 shown, a preparation process for a composite knitted fabric containing beads is characterized by including the following steps: S1, Softening and drying: The upper knitted fabric is softened by a softening impregnation device 9 and then dried; S2. Continuously apply the bursting beads. The bursting beads are positioned and quantitatively discharged through the positioning and quantitative discharging mechanism 1 of the bursting bead adding device 1, and the bursting beads are continuously sprinkled on the bottom high-loft hot air non-woven fabric to form more than three continuous bursting bead layers. The bursting beads are sprinkled on the support structure layer made of high-loft hot air non-woven fabric in a specific distribution pattern every 10 cm in length; S3. Spray glue and flip. The upper knitted fabric is subjected to positioning spray gluing treatment through the positioning spray gluing mechanism 2, and no glue is sprayed at the position corresponding to the bursting beads. After spraying glue, it is flipped and covered on the high-loft hot air non-woven fabric containing the bursting beads; S4. Seal the bursting beads. The high-loft hot air non-woven fabric and the knitted fabric containing the bursting beads are heated and rolled through the rolling mechanism 3 to seal the bursting beads between the bottom high-loft hot air non-woven fabric and the knitted fabric, forming a composite knitted fabric; S5. Dry and cure. The composite knitted fabric with the bursting beads sealed is dried and cured.

[0042] The composite knitted fabric includes: a knitted fabric layer and a high-loft hot air non-woven fabric layer; The addition amount of the bursting beads is: 1 - 100 beads; The thickness of the high-loft non-woven fabric is: 5 - 50 mm, and the gram weight is 10 - 60 gsm; The gram weight of the upper knitted fabric is: 10 - 35 gsm; Performance advantages of the composite knitted fabric 1. Unique functionality Sustained release function: Various functional substances such as antibacterial agents, fragrances, and moisturizing agents are encapsulated in the bursting beads. These substances can continuously play their roles through the slow release of the bursting beads, providing users with a long-term functional experience. For example, antibacterial bursting beads can continuously release antibacterial components, effectively inhibiting the growth of bacteria and keeping the knitted fabric clean and hygienic.

[0043] Targeted function: According to different needs, different functional substances can be selected to be encapsulated in the bursting beads, making the knitted fabric have specific functions. For example, for sports enthusiasts, bursting beads with moisture absorption and sweat discharge functions can be selected; for people pursuing comfortable sleep, aromatic bursting beads with the function of calming the nerves and helping sleep can be selected.

[0044] 2. Good comfort Softness: The knitted fabric itself has a soft characteristic, and the addition of the bursting beads does not affect its softness. On the contrary, the small size of the bursting beads makes the knitted fabric more delicate when touched, giving a comfortable touch.

[0045] Air permeability: The structure of the knitted fabric determines that it has good air permeability, allowing air to circulate freely and keeping the skin dry. The presence of the bursting beads does not hinder the air circulation, but may further improve the air permeability of the knitted fabric through its special structure.

[0046] Elasticity: Knitted fabric usually has a certain elasticity and can adapt to the movement and changes of the body. The addition of the bursting beads does not affect the elasticity of the knitted fabric, making the bursting bead knitted fabric more comfortable to wear.

[0047] 3. Durability Stability: The combination method of the bursting beads and the knitted fabric is carefully designed to ensure the stability of the bursting beads during use. The bursting beads will not easily fall off or break, and can maintain their functionality and aesthetics for a long time.

[0048] Wash resistance: The bursting bead knitted fabric has good wash resistance. After being washed many times, the functions and appearance of the bursting beads can still be maintained well. This makes the bursting bead knitted fabric more convenient and practical in daily use. As Figure 1 shown, the bursting bead adding device 1 includes a frame 40. A positioning and quantitative discharging mechanism 1 and a rolling mechanism 3 are sequentially arranged on the frame 40 in the direction from left to right. Above the rolling mechanism 3, there are a longitudinal positioning glue spraying mechanism 2 and a transverse glue spraying mechanism 20. The longitudinal positioning glue spraying mechanism 2 and the transverse glue spraying mechanism 20 are arranged in parallel. Below the longitudinal positioning glue spraying mechanism 2 and the transverse glue spraying mechanism 20, there are two parallel first guide rollers 21. On the left side of the primary rolling mechanism 3, there is a second guide roller 22 for turning over the upper knitted fabric.

[0049] As Figures 2 - 6 shown, the positioning and quantitative discharging mechanism 1 includes a storage hopper 41, a feeding pipe 42, a material limiting cover 43, and a feeding roller 44 that are sequentially arranged on the frame 40 from top to bottom. The inside of the material limiting cover 43 is a cavity 431. An arc-shaped limiting opening 432 for facilitating the rotation of the feeding roller 44 is formed on one side of the material limiting cover 43 close to the feeding roller 44. A plurality of bursting bead feeding grooves 441 are formed on the roller surface of the feeding roller 44 along the circumferential direction. There are three or more groups of the bursting bead feeding grooves 441 arrayed along the axial direction of the feeding roller 44. Two or more through grooves 431 are formed on the top of the material limiting cover 43 along the length direction. Above the through grooves 431, there is a partition plate 432 that can be inserted into the through grooves 431. Limiting pieces 430 are fixed on both sides of the top of the partition plate 432.

[0050] As Figures 7 - 14As shown in the figure, the rolling mechanism 3 includes a heating roller 31 and a bead fixing roller 32 rotatably arranged on the frame. The bead fixing roller 32 is arranged above the heating roller 31. The bead fixing roller 32 includes a hollow roller body 321. A rotating shaft 323 is fixed in the middle of the roller body 321. The rotating shaft 323 is fixedly connected to the inner side of the roller body 321 through a support bar 329. The roller body 321 can be divided into a front rolling area 341, a bead avoiding area 342, and a rear rolling area 343 along the axial direction. An annular groove 322 is formed on the surface of the bead avoiding area 342 along the circumferential direction. More than three annular grooves 322 are arranged in an array along the axial direction. A number of transverse rolling plates 326 are evenly arranged on the annular groove 322. The transverse rolling plates 326 and the roller body 321 form a bead accommodating cavity 320. A number of through holes 324 are formed at the bottom of the bead accommodating cavity 320. A plug core 325 is arranged on each through hole 324. The inner sides of each group of plug cores 325 arranged in the annular groove 322 are connected to a radial expansion mechanism 33. The plug core 325 radially moves in the bead accommodating cavity 320 through the radial expansion mechanism 33. An annular gap filling silica gel plate 327 is fixed at the notch of the bead accommodating cavity 320. The radial expansion mechanism 33 includes an inner fixing ring 331, an outer fixing ring 332, a rack 333, a gear 334, and an internal gear 335. The outer fixing ring 332 is arranged outside the inner fixing ring 331 and is concentric with it. A gear placement space 336 is formed between the outer fixing ring 332 and the inner fixing ring 331. Radial sliding grooves 337 are formed in the radial direction between the outer fixing ring 332 and the inner fixing ring 331. The number of the radial sliding grooves is the same as the number of each group of plug cores 325 on the annular groove 322. The rack 333 is slidably arranged in the radial sliding groove 337. The gear 334 is arranged in the gear placement space 336 and meshes with the rack 333. The internal gear 335 is arranged inside the outer fixing ring 331 and meshes with the gear 334. The end of the gear 334 is fixed with the plug core 325. One of the gears 334 is connected to a rotating motor 330. Side plates 328 are fixed on both sides of the outer fixing ring 332. The middle of the side plates 328 is fixed on the rotating shaft 323.

[0051] As Figure 15 shown, the longitudinal positioning glue spraying mechanism 2 includes a fixing strip 21. A first glue gun 22 that cooperates with the bead fixing roller 32 is arranged at the bottom of the fixing strip. The transverse glue spraying mechanism 20 includes a slide rail 201. A second glue gun 202 is arranged in the sliding direction of the slide rail.

[0052] As Figure 18As shown in the figure, the compliant impregnation device 9 includes an impregnation tank 91, and a number of impregnation rollers 92 arranged in an S shape are provided in the impregnation tank 91. Three partition plates 93 are arranged on the roller surface of the impregnation roller 92 along the axial direction.

[0053] Working principle: As Figures 1 - 18 shown in the figure, when adding a column of bursting beads, the material separating plate 432 is snapped into the through groove. At the same time, the controller controls the rotation of the rotary motor 330, so as to drive the rotary motor 330 of the radial expansion mechanism 33 to drive one of the gears 334 to rotate, thereby driving the internal gear 335 to rotate, and then driving the rack 333 to move outward along the radial direction until the top of the plug core 325 extends out of the notch of the bursting bead accommodating cavity, and cooperates with the annular gap filling silica gel plate to form a rolling surface same as that of the rolling area. Controlling the motor by the controller is a very mature technology at present, so it will not be elaborated in this case. Then, the bursting beads 403 are dropped into the limiting cover 43 through the feeding pipe 42 from the storage hopper 41, and are limited in the area between the two material separating plates 432 by the material separating plate 432. The excess bursting beads 403 are scraped off by the limiting cover 43, and only the bursting beads 403 falling into the bursting bead discharging groove 441 are used, so as to continuously and evenly scatter the bursting beads 403 onto the high-loft hot air non-woven fabric 401 at the bottom. At the same time, the upper knitted fabric 402 is sprayed with glue on the upper surface by the glue spraying mechanism 2, and no glue is sprayed at the position corresponding to the bursting beads. After spraying glue, it is turned over and covered on the high-loft hot air non-woven fabric layer containing the bursting beads. The bottom high-loft hot air non-woven fabric 401 containing the bursting beads and the upper knitted fabric 402 are rolled by the rolling mechanism 3, and the bursting beads are sealed between the bottom high-loft hot air non-woven fabric layer and the upper knitted fabric to form a composite knitted fabric containing bursting beads. The composite knitted fabric with the bursting beads 403 sealed is dried and cured, so as to produce a composite knitted fabric containing bursting beads, endowing the knitted fabric with more functions such as antibacterial, aromatic, moisturizing, etc., which can meet the needs of people for functional textiles. The combination of the bursting beads and the knitted fabric is firm, not easy to fall off, and has a long service life.

[0054] In order to meet the needs of users, if several more columns of bursting beads need to be added, only need to control the rotation of the partition plate motor 435 by the controller, so as to drive the rotation of the first gear 434, then drive the rotation of the first rack 433, and then drive the material separating plate 432 to move upward, so as to increase the range after the bursting beads 403 fall into the limiting cover 43. At the same time, the controller controls the rotation of the rotary motor 330, so as to drive the rotary motor 330 of the radial expansion mechanism 33 to drive one of the gears 334 to rotate, thereby driving the internal gear 335 to rotate, and then driving the rack 333 to move inward along the radial direction until the plug core 325 retracts into the through hole to form a groove, forming a bursting bead avoidance area. When the bursting bead avoidance area 432 is converted into a rolling area, the glue gun of the relative upper knitted fabric sprays glue, and when it is the bursting bead avoidance area, the glue gun does not spray glue, so as to cooperate with the material separating plate, enabling users to choose the number of columns of bursting beads to be added.
