And sleeving a material roll paper tube of the roll material to be fed on the mounting sleeve 130 from the left end, and then sequentially installing the mounting fixture blocks 140 and the fixture block nuts 131. The fixture block nuts 131 on the two sides are screwed, so that the two mounting fixture blocks 140 tightly abut against the left side and the right side of the paper roll, the raised blocks 141 on the mounting fixture blocks 140 extrude the paper roll to deform to a certain extent, and the inclined plane parts of the raised blocks 141 are embedded into the paper roll, so that the paper roll and the two mounting fixture blocks 140 cannot rotate relatively. The driving shaft 120 is driven to rotate by the driving motor and the transmission mechanism, so that the material roll paper tube which is sleeved on the mounting sleeve 130 and clamped and fixed by the two mounting fixture blocks 140 rotates along with the driving shaft 120, and the supply of the roll material is realized. When the position of the material roll along the axial direction needs to be adjusted: the sleeve nut 122 is screwed to make the sleeve nut 122 move along the axial direction of the driving shaft 120, and the mounting sleeve 130 always abuts against the sleeve nut 122 to the right under the action of the spring. When the sleeve nut 122 is rotated to move to the right, the mounting sleeve 130 drives the material roll to move to the right, and vice versa.
The mask body cloth is sequentially arranged in a nose bridge line discharging device 200, a nose bridge line welding device 300, an ear band line welding device 400, a folding device 500, a welding forming device 600, a finished product cutting device 700, a transverse power roller device and a longitudinal power roller device which are arranged among the devices. The roll supply device 100 drives each roll by a driving motor of each roll supply assembly so that each roll is maintained to be fed in synchronization.
Through adjusting the first regulation pole of horizontal power roller bearing subassembly 910 for install in the first driven roller 913 of first regulating block 914 can down support tightly first initiative roller 912 for the gauze mask body cloth of wearing to establish between first initiative roller 912 and the first driven roller 913 can be pressed from both sides tightly, works as when first initiative roller 912 rotates, gauze mask body cloth can be carried forward.
Similarly, through adjusting the second adjusting rod of the longitudinal power roller assembly 920, the second driven roller installed on the second adjusting block can be rightwards abutted against the second driving roller, so that the mask body fabric penetrating between the second driving roller and the second driven roller can be clamped tightly, and when the second driving roller rotates, the mask body fabric can be conveyed forwards.
The cloth of the mask body is continuously conveyed forwards intermittently by the transverse power roller assembly 910 and the longitudinal power roller device among the devices.
And in the process of continuously conveying the mask body cloth forwards intermittently, the nose bridge line segment is supplied to the mask cloth through the nose bridge line discharging device 200. First, a nose bridge wire is required to be provided on the right side of the nose bridge wire supply assembly 220. The bridge wire of the incoming material is passed between the first wire supply roller 221 and the second wire supply roller 222 and extended into the wire supply groove. Then, by rotating the adjusting rod, the adjusting rod drives the roller mounting base to slide upwards until the second wire supplying roller 222 mounted on the roller mounting base is pressed tightly upwards below the first wire supplying roller 221, and the nose bridge wire between the first wire supplying roller 221 and the second wire supplying roller 222 is clamped tightly.
Keeping the twist shaft 223, the pressure shaft 244 and the drive dial 232 rotating at the same rotational speed and at a constant speed.

Similarly, the second thread supplying roller 222 is also rotated by the first thread supplying roller 221, so that the nose bridge thread clamped between the first thread supplying roller 221 and the second thread supplying roller 222 is fed out from right to left by a certain distance. The rotation angle of the first wire supplying roller 221 and the second wire supplying roller 222 can be adjusted each time by adjusting the staggered angle of the two rubbing blocks 224, thereby adjusting the sending distance of the nasal bridge wire.
The bridge line enters the discharge chute from the line supply chute from right to left, the pressure lever shaft 244 rotates clockwise when viewed from front to back, and the swinging pressure lever 243 is driven by the pressure lever shaft 244 to move circularly. In the rotation process of the swing pressure rod 243, the pressure wheel at the end part of the swing pressure rod presses the pressing block from top to bottom, the pressing block compresses the spring and drives the cutter 241 to slide downwards, and the cutter 241 cuts off the nose bridge line below the cutter 241. The swinging pressure rod 243 continues to swing until the pressing wheel is separated from the pressing block, and the pressing block rebounds upwards under the action of the spring to drive the cutter 241 to reset upwards.
The driving turntable 232 drives the material pushing block 231 to slide back and forth through the connecting rod 233 in the rotating process: the material pushing block 231 slides forwards when the hinged 473 point of the connecting rod 233 and the driving turntable 232 moves from back to front; otherwise, the pusher block 231 slides backward. When the pushing block 231 slides forwards, the nose bridge line segment cut off and located in the discharge chute is pushed forwards, the two adjusting elastic pieces 211 arranged at the front end of the discharge chute are tightly pressed on the left side and the right side of the port of the discharge chute, the pushing block 231 pushes the nose bridge line segment until the two adjusting elastic pieces 211 are pushed outwards, and the nose bridge line segment drops downwards in a state that the two ends of the nose bridge line segment face the left-right direction at the port of the discharge chute.
The rubbing shaft 223, the pressing rod shaft 244 and the driving turntable 232 keep the same rotating speed and rotate at a constant speed, so that the nose bridge line is supplied leftwards and cut off, the action of pushing the nose bridge line section forwards is performed in sequence at the same beat, the stable supply of the nose bridge line section is realized, the intermittent feeding beat of the mask body cloth is consistent, when the mask body cloth is static below the discharge chute, the nose bridge line section drops downwards to the welding position of the mask body cloth, and the mask body cloth drives the nose bridge line section to enter the nose bridge line welding device 300 forwards.
The mask body cloth penetrates through the nose bridge line welding block 310 and the welding roller 320 of the nose bridge line welding device 300 in a finger-to-finger mode, the welding roller 320 installed on the welding adjusting block 330 can downwards abut against the nose bridge line welding block 310 through adjusting the welding adjusting screw 340, the mask body cloth penetrating between the nose bridge line welding block 310 and the welding roller 320 can be pressed at the upper end of the nose bridge line welding block 310 through the welding embossing on the welding roller 320, when the welding roller 320 rotates, the mask body cloth can be conveyed forwards, and meanwhile, a nose bridge line segment is welded and fixed on the mask body cloth under the action of the welding embossing and the nose bridge line welding block 310.
The mask body cloth that completes the welding of the nose bridge line enters the ear band line welding device 400 forward under the action of the transverse power roller device in front of the nose bridge line welding device 300.
When the ear band wire welding device 400 performs ear band wire welding, the ear band wire incoming materials are required to be respectively arranged at the left side and the right side of the ear band wire welding device 400. The ear belt line of the incoming material is wound around the wire arranging rod at the upper end of the wire supply mechanism 440 from bottom to top, then passes through the wire arranging hole of the wire arranging plate 445, then passes through the space between the driving wheel 442 and the clamping wheel 443, then sequentially winds around the detection wheel 448, the idle wheel 449 and the wire arranging wheel 454 of the wire outlet mechanism 450, passes through the wire inlet hole of the wire arranging block 455 from back to front, then passes through the wire outlet channel of the wire outlet assembly from back to front, and protrudes out of the wire outlet. The clamping cylinder 453 of the wire outlet mechanism 450 extends downwards to push the protruding part of the clamping block 452 downwards along the groove of the fixing block 451, so that the ear belt wire is clamped in the wire outlet channel.
When the mask body cloth needing to be welded with the ear strap line is placed below the ear strap line welding assembly 410, the wire taking pneumatic clamping jaw 462 of the wire taking assembly moves from front to back under the action of the servo linear module 461, and after the two clamping jaws of the wire taking pneumatic clamping jaw 462 reach the two sides of the head of the ear strap line protruding out of the wire outlet, the clamping jaws close to clamp the head of the ear strap line. At this time, the clamping cylinder 453 of the wire outlet mechanism 450 is released, the clamping block 452 slides upwards but still fits into the groove, and the ear ribbon wire is released and still passes through the wire outlet channel. The servo linear module 461 drives the wire-taking pneumatic clamping jaw 462 clamping the ear belt wire to move forwards from the wire outlet mechanism 450, and the ear belt wire is pulled forwards by the wire-taking pneumatic clamping jaw 462.
When the ear strap line is pulled out forward by the wire outlet mechanism 450, the driving wheel 442 and the clamping wheel 443 of the wire supply mechanism 440 clamp the ear strap line therebetween, so that the ear strap line pulls up the detection wheel 448, and when the detection photo 446 detects that the detection wheel 448 leaves its lower limit position, the wire supply servo motor 441 operates to drive the driving wheel 442 to rotate, so that the ear strap line is fed in the wire supply direction. After the wire taking assembly finishes the pulling-out action of the ear strap wire, the clamping cylinder 453 of the wire outlet assembly extends out to clamp the ear strap wire in the wire outlet channel again. Meanwhile, after the detection photo 446 detects that the detection wheel 448 slides down and returns to the lower limit position, the wire feeding servo motor 441 stops operating. So that the thread feeding servo motor 441 can feed thread according to the thread taking speed of the ear belt thread.
The wire feeding mechanism 440 on both sides of the ear strip wire welding assembly 410 moves simultaneously, after the wire taking pneumatic clamping jaw 462 finishes the pulling-out action of the ear strip wire, the lifting mechanism 422 of the ear strip wire taking and placing assembly 420 moves, the turntable on the upper part of the original hinged 473 point rotates under the driving of the lifting servo motor, the hinged 473 point moves from top to bottom, and the lifting platform connected by the lifting connecting rod 233 moves downwards along with the turntable. The wire taking and placing gripper mechanism 421 mounted on the lifting platform moves downwards, and the two wire taking and placing pneumatic clamping jaws 425 arranged along the front and back directions simultaneously descend to be consistent with the height of the ear belt wire pulled out from the wire outlet assembly. The two wire taking and releasing pneumatic clamping jaws 425 act, and the first wire taking and releasing clamping jaw 423 and the second wire taking and releasing clamping jaw 424 respectively clamp the front end and the rear end of the pulled ear belt wire section. Then, the thread cutting mechanism 470 arranged at the thread outlet is actuated, the cutting cylinder 474 drives the hinge 473 to extend, the scissors 472 are pushed by the hinge 473 to move towards the ear thread at the thread outlet, and the scissors 472 in the open state is used for contacting the blocking part with the blocking column 475 in the movement process, so that the scissors 472 are closed in a staggered manner, and the ear thread is cut between the thread outlet channel and the thread taking and placing gripper mechanism 421.
After the trimming mechanism 470 trims the ear strap, the two wire-taking and placing pneumatic clamping jaws 425 respectively clamp the front and rear ends of the ear strap for welding. The rotating disc of the lifting mechanism 422 continuously rotates, so that the hinge 473 point of the rotating disc continuously moves up and down repeatedly, and the lifting platform moves up and down repeatedly along with the hinge 473 point. Holding the ear belt line segment get line hand claw mechanism 421, before descending again and targetting in place, drive through rotatory servo motor 426 first get and put the pneumatic clamp of line and the pneumatic clamp of second get and put the line for originally respectively stretch out along the fore-and-aft direction first get unwrapping wire clamping piece 423 and the unwrapping wire clamping piece 424 of second get, respectively towards the middle part direction of ear belt line welding component 410 is toward inwards upset, originally along the ear belt line segment that the fore-and-aft direction straightens two get and put the effect of the pneumatic clamping jaw 425 of line and bend into the arcuation. Because the length of the first wire taking and releasing clamping piece 423 is greater than that of the second wire taking and releasing clamping piece 424, when the rotary servo motor 426 drives the two wire taking and releasing pneumatic clamping jaws 425 to rotate, a connecting line of two end parts of an ear strap segment can form a certain included angle with the front and back direction, and the ear strap welding requirement of the folding mask is met. When the wire taking and releasing paw mechanism 421 is driven by the lifting platform to descend to the right position again, the ends of the ear belt wire sections respectively clamped by the two wire taking and releasing pneumatic clamping jaws 425 are located at the welding position of the mask body cloth.
The lifting cylinder 412 of the ear band wire welding assembly 410 extends downwards, the welding head 411 which is installed in a sliding mode slides downwards along with the lifting cylinder, until the four welding heads 411 tightly press four ports of two ear band wire sections clamped by the two wire taking and placing claw mechanisms 421 onto the cloth of the mask body, and the ultrasonic generator 640 operates to perform welding. When the welding is completed, two the action of getting and putting the pneumatic clamping jaw 425 of line loosens the ear area line to before the elevating platform is accomplished to reciprocating motion from top to bottom next time, drive two respectively through two rotatory servo motor 426 get and put the pneumatic clamping jaw 425 of line, make first get unwrapping wire clamping piece 423 and the outward rotation of second get unwrapping wire clamping piece 424, first get unwrapping wire clamping piece 423 and second get unwrapping wire clamping piece 424 again and be in get the top of line mechanism 460 and stretch out to the front and back respectively.
In the process that the lifting mechanism 422 drives the lifting platform to reciprocate up and down, the two wire taking and placing pneumatic clamping jaws 425 and the two rotary servo motors 426 of the wire taking and placing gripper mechanism 421 are matched with each other, and the actions of rotating wire taking and rotating wire releasing are repeatedly performed. So that each section of ear belt line on the left side and the right side can be quickly welded on the cloth of the mask body.
The mask body cloth that completes the ear band line welding enters the folding device 500 forward. By rotating the screw adjustment rod 550, the distance between the heads of the first and second hinges 473 and 473 threadedly mounted on both ends of the screw adjustment rod 550 can be adjusted, thereby adjusting the angle at which the front end of the folding guide 530 is tilted upward. The position of the mounting base plate 510 can be adjusted in the left-right direction by adjusting the third adjusting screw, so that the folding roller 520 and the folding guide plate 530 are aligned with the mask body cloth along the center line. Under the action of the folding rollers 520 and the folding guide plates 530, the left and right sides of the mask body cloth are folded downwards towards the middle, and enter the front longitudinal power roller assembly 920 in a folded state.
