[0028] The mask fabric welding assembly provided in this application includes a pod conveyor, a fabric roller group, and a forming welding roller group arranged sequentially along the fabric conveying direction. The fabric roller group includes a first roller and a second roller distributed vertically, and the fabric includes a first fabric layer and a second fabric layer passing through the space between the first roller and the second roller. The pod conveyor includes a pod storage section and a pod conveying section. The pod conveying section is provided with a nozzle extending between the first roller and the second roller. The nozzle is provided with a channel connected to the pod storage section. The pod conveying section is connected to a first driving member and is used to output pods through the nozzle at regular intervals and in a quantitative manner under the drive of the first driving member, so that the pods are wrapped between the first fabric layer and the second fabric layer and conveyed to the forming welding roller group. The forming welding roller group includes a forming welding pattern roller and an ultrasonic transducer located at the lower end of the forming welding pattern roller. The forming welding pattern roller is provided with a pod welding interface, and the upper end of the ultrasonic transducer is provided with a welding head that cooperates with the pod welding interface. By setting up a capsule conveyor to transport the capsules between the first and second fabric layers, the capsules move to the forming and welding roller group under the action of the first and second fabric layers. Then, the forming and welding roller and ultrasonic transducer weld the fabric to wrap the capsules, realizing the function of producing masks with capsules. Moreover, there is no need to open the fabric, ensuring the reliability of the capsule wrapping and improving product quality.

[0029] like Figure 1 As shown, one embodiment of this application provides a mask fabric welding assembly, including a popping bead conveyor, a fabric roller group, and a forming welding roller group arranged sequentially along the fabric conveying direction;

[0030] The fabric roller assembly includes a first roller 100 and a second roller 200 distributed vertically, and the fabric includes a first fabric layer 310 and a second fabric layer 320 passing between the first roller 100 and the second roller 200.

[0031] The popping bead conveying component includes a popping bead storage section 410 and a popping bead conveying section 420. The popping bead conveying section 420 is provided with a nozzle 430 extending between the first roller 100 and the second roller 200. The nozzle 430 is provided with a channel connected to the popping bead storage section 410. The popping bead conveying section 420 is connected to a first driving member 440 and is used to output popping beads through the nozzle 430 in a timed and quantitative manner under the drive of the first driving member 440, so that the popping beads are wrapped between the first fabric layer 310 and the second fabric layer 320 and conveyed to the forming and welding roller group.

[0032] The forming welding roller assembly includes a forming welding pattern roller 500 and an ultrasonic transducer (not shown) located at the lower end of the forming welding pattern roller 500. The forming welding pattern roller 500 is provided with a burst bead welding interface 510, and the upper end of the ultrasonic transducer is provided with a welding head (not shown) that cooperates with the burst bead welding interface 510.

[0033] The mask fabric welding assembly provided in this application is one of the components in a mask machine. Typically, a mask machine includes, but is not limited to, a fabric feeding machine, a nose wire installation machine, a fabric welding assembly, a mask folding assembly, an automatic ear loop attachment assembly, an automatic edge sealing machine, and a mask cutting assembly. The fabric feeding machine, nose wire installation machine, fabric welding assembly, mask folding assembly, automatic ear loop attachment assembly, automatic edge sealing machine, and mask cutting assembly are arranged sequentially from front to back along the fabric conveying direction, which will not be elaborated further.

[0034] The capsule delivery component includes a capsule storage section 410 and a capsule delivery section 420. The capsule storage section 410 stores capsules, each capsule having an outer skin that is a soft structural layer and containing a liquid. This liquid is a volatile liquid, such as a medicinal liquid, fruit flavoring, fragrance, and / or natural plant extract, and is not limited thereto. The mask fabric welding assembly provided in this application, when used in a mask-making machine, transforms the passive defense of traditional masks into active protection, allowing all volatile substances that affect respiration to be used in this mask.

[0035] The popping bead conveying unit 420 is provided with a nozzle 430 extending between the first roller 100 and the second roller 200. The nozzle 430 is provided with a channel connected to the popping bead storage unit 410, so that the popping beads stored in the popping bead storage unit 410 can enter the channel, and then, under the drive of the first driving member 440, popping beads are output through the nozzle 430 in a timed and quantitative manner.

[0036] As one possible implementation, the first drive element 440 can be any one of a motor, a cylinder, or a lead screw assembly.

[0037] For example, taking a motor as an example, the power output shaft of the motor is equipped with a metering structure. By controlling the rotation of the motor, the metering structure is rotated. For example, one rotation can output a popping bead; or rotating a certain angle (such as 90 degrees or 120 degrees, etc.) can output a popping bead, without limitation.

[0038] For example, taking a cylinder as an example, the cylinder's drive shaft extends into the channel, and one popping bead can be output by the cylinder's drive shaft extending once.

[0039] For example, taking a lead screw assembly as an example, the threaded portion of the lead screw assembly is placed inside the channel, and the popping beads are confined to the channel and the threaded portion of the lead screw assembly. By driving the lead screw assembly to rotate, the popping beads are arranged to move forward, and by controlling the rotation angle of the lead screw assembly, only one popping bead is output to the channel at a time.

[0040] It should be noted that the first driving component 440 described above, which can be any one of a motor, cylinder, or lead screw assembly, is merely an illustrative example of an embodiment of this application and not a specific limitation thereof. In other embodiments, other methods can be used to output the popping beads, such as by air jet, as long as the function of timed and quantitative output of popping beads can be achieved.

[0041] During the conveying process, the fabric passes through a fabric roller assembly, which includes a first roller 100 and a second roller 200 distributed vertically. The fabric includes a first fabric layer 310 and a second fabric layer 320. The first fabric layer 310 and the second fabric layer 320 move from the upstream station to the fabric roller assembly and pass between the first roller 100 and the second roller 200. That is, the first fabric layer 310 and the second fabric layer 320 are separate before passing through the fabric roller assembly, so that the burst beads are wrapped between the first fabric layer 310 and the second fabric layer 320 and conveyed to the forming and welding roller assembly.

[0042] As one possible implementation, the first fabric layer 310 and the second fabric layer 320 can be single-layer fabrics. For example, the first fabric layer 310 can serve as the outer layer of the mask, which is a waterproof layer and can be made of non-woven fabric. The non-woven fabric layer is mainly used to prevent droplets and protect the inner layer from contamination. The second fabric layer 320 can serve as the middle layer of the mask, which is a filter layer and can be made of meltblown fabric, which can effectively filter suspended particles of bacteria.

[0043] As another possible implementation, the first fabric layer 310 and / or the second fabric layer 320 can be multi-layered fabrics. For example, taking the first fabric layer 310 as a multi-layered structure, the first fabric layer 310 includes an inner layer and a filter layer, and the filter layer can be provided with at least one layer, such as two, three, or more layers, without limitation. The second fabric layer 320 can be a single-layered structure, such as a waterproof layer; the second fabric layer 320 can also be a multi-layered structure, for example, the second fabric layer 320 includes a non-woven fabric layer and a hot air cotton layer, without limitation.

[0044] When the first fabric layer 310 and the second fabric layer 320 wrap the popping beads and convey them to the forming and welding roller group, the forming and welding roller 500 and the ultrasonic transducer work together to weld and shape the fabric by using ultrasonic welding technology, so as to avoid the popping beads being broken and facilitate the subsequent process of cutting the fabric to obtain a mask.

[0045] The forming and welding roller 500 is also equipped with a burst bead welding interface 510. The upper end of the ultrasonic transducer is equipped with a welding head that cooperates with the burst bead welding interface 510. The burst bead welding interface 510 corresponds to the position of the burst bead. Specifically, by controlling the rotation speed of the forming and welding roller 500 and the output speed of the burst bead conveyor, the burst bead welding interface 510 can accurately correspond to the position of the burst bead to weld the fabric to wrap the burst bead.

[0046] As one possible implementation, the bursting bead fusion joint 510 can be circular, directional, elliptical, triangular, polygonal or other shapes. For example, the bursting bead fusion joint 510 can be an eight-segment bursting bead fusion joint 510, without limitation.

[0047] When the capsule is subjected to sufficient external pressure, its outer skin ruptures, causing the volatile liquid to leak out and release volatile substances. These substances then enter the body through the respiratory system during the wearer's breathing, exerting their corresponding effects. In implementation, the first roller 100 and / or the second roller 200 are equipped with capsule retraction grooves 600. For example, the capsule retraction groove 600 can be provided on the first roller 100 or the second roller 200, or grooves can be simultaneously provided on both the first roller 100 and the second roller 200 to form the capsule retraction groove 600. The depth of the capsule retraction groove 600 is adapted to the diameter of the capsule, preventing the fabric and capsule from breaking as they pass through the first roller 100 and the second roller 200, thus ensuring product quality.

[0048] The mask fabric welding assembly provided in this application includes a capsule conveyor, a fabric roller group, and a forming welding roller group arranged sequentially along the fabric conveying direction; the fabric roller group includes a first roller 100 and a second roller 200 distributed vertically, and the fabric includes a first fabric layer 310 and a second fabric layer 320 passing through the space between the first roller 100 and the second roller 200; the capsule conveyor includes a capsule storage section 410 and a capsule conveying section 420, the capsule conveying section 420 being provided with a nozzle 430 extending between the first roller 100 and the second roller 200, and the nozzle 430 being provided with a capsule storage section 410. The material section 410 is connected to the channel, and the burst bead conveying section 420 is connected to the first driving member 440. It is used to output burst beads through the nozzle 430 at regular intervals and in a quantitative manner under the drive of the first driving member 440, so that the burst beads are wrapped between the first fabric layer 310 and the second fabric layer 320 and conveyed to the forming and welding roller group. The forming and welding roller group includes a forming and welding pattern roller 500 and an ultrasonic transducer located at the lower end of the forming and welding pattern roller 500. The forming and welding pattern roller 500 is provided with a burst bead welding interface 510, and the upper end of the ultrasonic transducer is provided with a welding head that cooperates with the burst bead welding interface 510. By setting up a capsule conveyor to transport the capsules between the first fabric layer 310 and the second fabric layer 320, the capsules move to the forming and welding roller group under the action of the first fabric layer 310 and the second fabric layer 320. Then, the forming and welding roller 500 and the ultrasonic transducer weld the fabric to wrap the capsules, realizing the function of producing masks with capsules. Moreover, there is no need to open the fabric, ensuring the reliability of the capsule wrapping and improving product quality.

[0049] Furthermore, the capsule storage unit 410 includes a second drive member 411, a capsule dial box 412, a hose 413, and a dial brush 414. The second drive member 411 is disposed on the capsule dial box 412, and the dial brush 414 is disposed inside the capsule dial box 412 and connected to the second drive member 411. The capsule dial box 412 is provided with a capsule leakage hole, which is connected to the capsule conveying unit 420 through the hose 413.

[0050] In implementation, the second driving component 411 can refer to the first driving component 440 described above, without limitation. Optionally, the second driving component 411 can also be a geared motor, which drives the dial brush 414 to smoothly guide the burst beads contained in the burst bead dial box 412 into the hose 413, thereby allowing the burst beads to enter the burst bead conveying section 420.

[0051] Optionally, two burst bead conveying units 420 are provided, with the nozzles 430 of the two burst bead conveying units 420 corresponding to the positions of the outer regions of the left and right nostrils, respectively. Similarly, the forming welding roller is provided with two burst bead welding joints 510 for better results.

[0052] Optionally, the mask fabric welding assembly provided in this application further includes a third roller 700 disposed between the fabric roller group and the forming welding roller group. The third roller 700 is used to guide the third fabric layer 330 so that the third fabric layer 330 is bonded to the first fabric layer 310 and the second fabric layer 320.

[0053] In implementation, the first fabric layer 310, the second fabric layer 320, and the third fabric layer 330 are arranged sequentially from bottom to top. Taking an N95 mask as an example, an N95 mask includes a 5-layer structure. The second fabric layer 320 and the third fabric layer 330 are both single-layer fabric layers, while the first fabric layer 310 includes 3 fabric layers. Figure 1 As shown.

[0054] Furthermore, the third roller 700 is provided with a burst bead avoidance groove 600 to avoid the burst beads from being squeezed out.

[0055] Secondly, this application also provides a mask machine, including the mask fabric welding assembly as described above.

Specifically, the structure and implementation principle of the aforementioned fabric feeding machine, nose wire installation machine, fabric welding assembly, mask folding assembly, automatic ear loop attachment assembly, automatic edge sealing machine, and mask cutting assembly can refer to common mask machines on the market and will not be elaborated further.
