[0035] In actual application, the cloth is first wound forward on the upper surface of the two upper winding rollers 29, and then wound downward on a lower winding roller 30. The lower winding roller 30 turns the cloth so that the cloth is transported backward and passes through the sponge strip end of the sponge strip sticking mechanism 31 and then wound on another lower winding roller 30.

[0036] In this embodiment, the sponge strip mechanism 31 includes a mounting plate 32 arranged on the machine 1, a sponge strip stripping module 33 arranged on the mounting plate 32, a flat sponge strip module 34 arranged on the mounting plate 32 and located at the stripping end of the sponge strip stripping module 33, and a support plate 35 installed on the mounting plate 32 and located below the stripping end of the sponge strip stripping module 33.

The sponge strip head 39 is connected to the mounting plate 32 in a lifting and sliding manner. Specifically, the sponge strip stripping module 33 can adopt an existing stripping mechanism, which will not be described in detail here.

[0037] In actual application, the support plate 35 supports the position of the sponge strip to be pasted on the cloth, the sponge strip peeling module 33 peels off the sponge strip on the material strip and recycles the waste material strip, and the suction holes on the sponge strip head 39 suck the peeled sponge strip tightly onto the sponge strip head 39, then, the sponge motor 36 drives the eccentric wheel 37 to rotate, the rotating eccentric wheel 37 drives the connecting rod 38 to swing, and the swinging connecting rod 38 drives the sponge strip head 39 to move downward together with the sponge strip until the sponge strip head 39 cooperates with the support plate 35 to stick the sponge strip on the cloth.

[0038] In this embodiment, the sponge strip sticking mechanism 31 also includes an air blowing pipe 40 installed on the mounting plate 32, and the air blowing pipe 40 is provided with a plurality of air blowing holes. The air blowing pipe 40 is located on the lower inner side of the stripping end of the sponge strip stripping module 33, and the air blowing holes are arranged obliquely upward toward the stripping end of the sponge strip strip stripping module 33.

[0039] When the sponge strip is peeled off, the air blowing pipe 40 blows air to the sponge strip obliquely from bottom to top to make the sponge strip smooth, which is conducive to the sponge strip sticking head 39 to absorb the sponge strip stably.

[0040] In this embodiment, the double-sided folding device 14 includes a double-sided folding frame 41 installed on the machine 1, a first guide roller 42 rotatably connected to the double-sided folding frame 41, a second guide roller 43 rotatably connected to the double-sided folding frame 41, two pre-flanging wheels 44 rotatably arranged on the double-sided folding frame 41, a guide plate 45 installed on the double-sided folding frame 41 and located below the pre-flanging wheels 44, a double-sided folding mechanism 46 installed on the double-sided folding frame 41 and arranged opposite to the inner side of the guide plate 45, and an outer side of the guide plate 45. The pressing wheel group 47 is arranged opposite to each other, and the distance adjustment mechanism 48 is installed on the double-sided folding frame 41 and used to adjust the distance between the pressing wheel group 47 and the guide plate 45.

[0041] In actual application, the fabric after welding the breathing valve is passed through the first guide roller 42, the second guide roller 43 and the two pre-flanging wheels 44 in sequence, and passes through the double-sided folding gap between the guide plate 45 and the double-sided folding mechanism 46. The two pre-flanging wheels 44 pre-fold the two sides of the fabric, and the double-sided folding gap performs double-sided folding on the pre-folded fabric, so that the two sides of the fabric are folded inward. During the double-sided folding process, the pressing wheel group 47 presses the fabric against the guide plate 45, so that the fabric can move stably along the guide plate 45. The breathing valve on the fabric passes through the avoidance channel 49, and then the double-sided folded fabric is conveyed forward through the eighth roller traction mechanism 26, and the breathing valve on the fabric conveyed forward faces upward. This structural design occupies a small space, and can make the breathing valve of the double-sided folded fabric face upward when conveyed forward, which is conducive to simplifying the structure of the subsequent processing mechanism, thereby simplifying the structure of the machine.

The rotation direction of the brush 52 of the first headband outward mechanism 22 is opposite to the rotation direction of the brush 52 of the second headband outward mechanism 27. In actual application, as the fish-shaped mask body moves, the outward motor 50 drives the rotating shaft 51 to rotate synchronously with the brush 52. The rotating brush 52 moves the headband on the fish-shaped mask body away from the slitting mechanism 24 to prevent the slitting mechanism 24 from cutting the headband when it is working.

[0043] In this embodiment, the welding breathing valve device 12 includes a base 53 slidably connected to the machine table 1, a reciprocating mechanism 54 driven by the base 53, a conveying mechanism 55 installed on one side of the base 53, a discharge position 56 arranged at the discharge end of the conveying mechanism 55, a visual detection mechanism 57 mounted above the discharge position 56, a material control mechanism 58 installed at the discharge end of the conveying mechanism 55 and located on the feeding side of the discharge position 56, a turntable 59 rotatably arranged on the base 53 and located on one side of the discharge position 56, a rotating drive mechanism 60 installed on the base 53 and used to drive the turntable 59 to rotate, a transfer mechanism 61 installed on the base 53, an angle adjustment mechanism 62 installed at the transfer end of the transfer mechanism 61, and an angle adjustment mechanism 63 installed on the angle adjustment mechanism 64. The pick-and-place piece 63 at the angle adjustment end of the mechanism 62, the pressing mechanism 64 installed on the base 53 and located above the turntable 59, and the ultrasonic welding mechanism 65 installed on the base 53 and located below the turntable 59, the turntable 59 is provided with a plurality of placement holes 66 along the circumferential direction, the inner wall of the placement hole 66 is provided with an elastic support piece 67 for controlling the falling of the breathing valve, the ultrasonic welding mechanism 65, one of the placement holes 66, and the pressing mechanism 64 are correspondingly arranged, the pick-and-place piece 63 is movably arranged above the turntable 59 and the discharge position 56, and the angle adjustment mechanism 62 is electrically connected to the visual detection mechanism 57; specifically, the pick-and-place piece 63 adopts a suction cup, and the pressing mechanism 64 and the ultrasonic welding mechanism 65 respectively adopt existing mechanisms, which will not be repeated here.

[0044] In actual application, the conveying mechanism 55 conveys the breathing valve to the discharge position 56. When there is a breathing valve at the discharge position 56, the material control mechanism 58 blocks the subsequent breathing valves to separate the two adjacent breathing valves, so as to control the breathing valves to be supplied to the discharge position 56 one by one. The visual detection mechanism 57 visually locates the breathing valve at the discharge position 56 to detect the direction of the breathing valve and feeds back the detection result to the angle adjustment mechanism 62. The transfer mechanism 61 drives the angle adjustment mechanism 62 to move the pick-up and placement member 63 to the discharge position 56, so that the pick-up and placement member 63 picks up the breathing valve. , and the transfer mechanism 61 then drives the pick-and-place member 63 to load the breathing valve into the placement hole 66 of the turntable 59, and the elastic support member 67 supports the breathing valve. In the process of transferring the breathing valve, the angle adjustment mechanism 62 drives the pick-and-place member 63 to rotate the breathing valve to the required angle according to the detection result of the visual detection mechanism 57, until the breathing valve picked up by the pick-and-place member 63 is in the correct direction, and the rotation drive mechanism 60 drives the turntable 59 to rotate intermittently, so that the breathing valves on the turntable 59 rotate one by one to the bottom of the pressing mechanism 64, and the cloth is above the welding head of the ultrasonic welding mechanism 65. The rotating disk 59 moves downward. When the breathing valve hole of the fabric corresponds to the placement hole 66 carrying the breathing valve, the pressing end of the pressing mechanism 64 presses down the breathing valve in the placement hole 66. In the process of pressing down the breathing valve, the elastic support member 67 undergoes elastic deformation, causing the breathing valve to fall. After the breathing valve falls, the elastic support member 67 can recover elastically to support the subsequent breathing valve. The breathing valve is pressed down to the breathing valve hole of the fabric, and under the cooperation of the pressing mechanism 64 and the ultrasonic welding mechanism 65, the breathing valve is welded to the breathing valve hole of the fabric. During the process of welding the breathing valve, since the cloth is continuously moving, the reciprocating mechanism 54 first drives the base 53 to move synchronously with the conveying mechanism 55, the material discharging position 56, the visual detection mechanism 57, the material control mechanism 58, the turntable 59, the transfer mechanism 61, the pressing mechanism 64 and the ultrasonic welding mechanism 65, until the welding of the breathing valve is completed, the pressing mechanism 64 and the ultrasonic welding mechanism 65 are reset, and the reciprocating mechanism 54 drives the base 53 to reset and move with each mechanism, so as to weld the next breathing valve on the next breathing valve hole of the cloth. The welding breathing valve device 12 has stable feeding of the breathing valve, can realize follow-up welding of the breathing valve, and improves the quality of the welding breathing valve.

[0045] In this embodiment, the transfer mechanism 61 includes a seat body 68 mounted on the base 53, a swing arm 69 rotatably connected to the seat body 68, a rotating driver 70 mounted on the seat body 68 and drivingly connected to one end of the swing arm 69, a translation slider 71 horizontally slidably connected to the seat body 68, and a lifting arm 72 lifting and slidingly connected to the translation slider 71. The angle adjustment mechanism 62 is mounted on the bottom end of the lifting arm 72. The seat body 68 is provided with a U-shaped groove 73 with an opening facing downward. The other end of the swing arm 69 is provided with a driving guide groove 74 connected to the U-shaped groove 73. The top end of the lifting arm 72 is rotatably connected with a guide wheel 75. The guide wheel 75 penetrates the driving guide groove 74 and then extends into the U-shaped groove 73. The guide wheel 75 rolls against the inner wall of the driving guide groove 74 and the inner wall of the U-shaped groove 73 respectively. The two ends of the U-shaped groove 73 are respectively arranged corresponding to a placement hole 66 of the turntable 59 and the discharge position 56; specifically, the rotating driver 70 and the angle adjustment mechanism 62 can both use motors.

[0046] In practical applications, the rotary driver 70 drives the swing arm 69 to swing back and forth, and the inner wall of the driving guide groove 74 of the swinging swing arm 69 will contact the guide wheel 75 to move along the inner wall of the driving guide groove 74. At the same time, the guide wheel 75 moves along the track of the U-shaped groove 73, and under the translation action of the translation slider 71, the lifting arm 72 can achieve reciprocating translation and lifting actions, so that the pick-and-place member 63 can continuously complete the action of picking up the breathing valve on the material position 56 to the placement hole 66 of the turntable 59. The structural design of the transfer mechanism 61 is ingenious. Compared with the method of using a mechanical arm or a joint manipulator in the prior art, it can reduce costs and has high efficiency in transferring the breathing valve.

[0047] In this embodiment, the welding breathing valve device 12 also includes a flexible material channel 76 and a vibration disk 77. The two ends of the flexible material channel 76 are respectively connected to the discharge port of the vibration disk 77 and the feed end of the conveying mechanism 55. In actual application, the vibration disk 77 supplies the breathing valve to the flexible material channel 76, and the breathing valve in the flexible material channel 76 moves to the conveying mechanism 55, and the conveying mechanism 55 conveys the breathing valve to the discharge position 56. Since the flexible material channel 76 can swing flexibly, when the conveying mechanism 55 moves, the flexible material channel 76 can follow and will not pull the vibration disk 77, so that stable feeding of the breathing valve can be achieved. Specifically, the flexible material channel 76 is composed of a plurality of chain links.

[0048] In this embodiment, the material control mechanism 58 includes a material control cylinder 78 installed at the discharge end of the conveying mechanism 55 and a material control rod 79 installed on the piston rod of the material control cylinder 78. The material control rod 79 can extend into the junction of the conveying mechanism 55 and the discharge position 56. In actual application, the material control cylinder 78 drives the material control rod 79 to move back and forth, so that the material control rod 79 extends or retracts to realize material control of the breathing valve.

[0049] The visual inspection mechanism 57 includes an annular light source 81 installed above the material discharging position 56 and a visual camera 82 mounted above the annular light source 81. An activity space for the pick-up and drop-down member 63 to enter and take materials is provided between the annular light source 81 and the visual camera 82. The visual camera 82 is an industrial camera. The visual camera 82 takes a picture of the breathing valve on the material discharging position 56, obtains an image of the breathing valve, and detects the direction of the breathing valve. The annular light source 81 emits light and irradiates the breathing valve at the material discharging position 56, so that the visual camera 82 can clearly take a picture of the breathing valve.

[0050] The elastic support member 67 includes a plurality of rotating supports 83 and a plurality of elastic limiting pieces 84. The middle portion of the rotating supports 83 is rotatably connected to the inner wall of the placement hole 66. One end of the elastic limiting piece 84 is mounted on the rotating disk 59, and the other end of the elastic limiting piece 84 extends into the placement hole 66. One end of the rotating supports 83 extends into the placement hole 66, and the other end of the rotating supports 83 is connected to the rotating disk 59 via a spring 85. The plurality of rotating supports 83 and the plurality of elastic limiting pieces 84 are distributed in an annular array on the inner wall of the placement hole 66, and the plurality of rotating supports 83 are spaced apart from the plurality of elastic limiting pieces 84. When the breathing valve is placed in the placement hole 66, one end of the elastic limiting piece 84 extending into the placement hole 66 contacts the peripheral side wall of the breathing valve, the rotating supports 83 support the breathing valve, and the elastic limiting piece 84 limits the breathing valve, thereby improving the position accuracy and stability of the breathing valve in the placement hole 66. When the pressing end of the pressing mechanism 64 presses down the breathing valve in the placement hole 66, the end of the rotating bracket 83 extending into the placement hole 66 will rotate downward, and the other end of the rotating bracket 83 stretches the spring 85 until the breathing valve falls onto the breathing valve hole of the fabric and the welding is completed. The pressing end of the pressing mechanism 64 is reset, and the rotating bracket 83 is reset and rotated under the action of the rebound force of the spring 85, so that the rotating bracket 83 can support the subsequent breathing valve.

[0051] Specifically, the material discharging position 56 is equipped with a sensor 80, and the material control mechanism 58 and the transfer mechanism 61 are respectively electrically connected to the sensor 80. The sensor 80 is used to sense whether there is a breathing valve on the material discharging position 56, and to feed back a signal to the material control mechanism 58 and the transfer mechanism 61, so that the material control mechanism 58 and the transfer mechanism 61 can perform corresponding actions.

[0052] All technical features in this embodiment can be freely combined according to actual needs.

[0053] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
