Referring to fig. 4, when the pressing plate 77 presses the ear strap against the inner wall of the channel 72, the cutting mechanism 9 cuts the ear strap, and the cutting mechanism 9 is specifically a pair of scissors driven by a servo motor through a link rod.

Since the shape of the ear belt changes during the cutting and welding, the ear belt is stretched straight during the cutting, and therefore, when the holding arm 6 initially holds the ear belt, the ear belt is also stretched straight, and after the holding arm 6 is driven by the second driving device 5 to rotate, the two ends of the cut ear belt in the length direction approach each other, so that the flexible ear belt becomes arc-shaped.

Referring to fig. 5, to prevent the middle part of the arc-shaped ear strap from moving to the blade under the action of its own elasticity to affect the subsequent welding process, a guide plate 8 is used to ensure that the middle part of the ear strap is positioned at both sides of the blade during welding.

The deflector 8 is located the one side that centre gripping arm 6 is close to the lamellar body, and deflector 8 fixed mounting is on first support 2, and the moving direction of material extends on workstation 1 is followed to the one end of deflector 8 length direction. The guide plate 8 consists of three parts, a connecting part 81, a transition part 82 and a guide part 83, which are integrally formed, the connecting part 81 is fixedly connected with the first bracket 2, the guide part 83 extends in the moving direction of the material on the working table 1 and is fixedly connected with the guide plate 10 at the end far from the fixing part, and the transition part 82 is positioned between the connecting part 81 and the guide part 83.

Since the guide plate 8 is located on the side of the holding arm 6 close to the sheet body, when the holding arm 6 grips the ear belt and rotates, the middle portion of the ear belt hangs down under the action of gravity, and in order to enable the guide portion to intercept the middle portion of the ear belt, the position of the guide plate 8 should be located below the holding arm 6. Meanwhile, in order to improve the intercepting effect of the ear strap, in the moving direction of the material on the workbench 1, the length of the transition part 82 is limited and is smaller than the length of the cut ear strap, otherwise, the situation that the ear strap is clamped on the transition part 82 in the rotating process of the clamping arm 6 can occur.

After the ear belt is obtained by the clamping arm 6, the second driving device 5 drives the clamping arm 6 to rotate, the transition part 82 intercepts the middle part of the ear belt, when the two ends of the ear belt are welded on the sheet body and the sheet body continues to move on the workbench 1, a certain gap must exist between the guide plate 8 and the workbench 1, so that the ear belt welded on the sheet body is sleeved on the transition part 82 and sleeved on the guide part 83 in the later moving process, and the subsequent ear folding process is facilitated.

Meanwhile, in order to enhance the function of the transition portion 82 for intercepting the ear belt, a stopper 84 is added to the transition portion 82, and the stopper 84 is fixedly connected with the connecting portion 81 and is positioned above the guiding portion 83. In this application embodiment, limiting plate 84 is the bent plate of smooth bending, and the bending part of limiting plate 84 is towards centre gripping arm 6, and when centre gripping arm 6 rose and rotated, the earlap contacted earlier and slided along limiting plate 84 with the curved surface of limiting plate 84, and smooth camber makes limiting plate 84 can not block the earlap, and the bending part of limiting plate 84 plays the effect of sheltering from to the earlap simultaneously, avoids centre gripping arm 6 at the in-process of quick pivoted, and the earlap swing is failed to overlap and is established on guide portion 83.

After the ear strap is placed on the lamellar body, first welding mechanism 15 welds the ear strap on the lamellar body, and the welding mode of gauze mask has welding modes such as ultrasonic welding etc. and first welding mechanism 15 can be for installing the ultrasonic bonding machine on first support 2.

After the welding is accomplished, lamellar body and ear area remove together, and the ear area landing from deflector 8, then laminate gradually on the lamellar body in the contact process with guide board 10, when carrying out next ear area welding process, dial positive mechanism and dial the ear area just. In this process, the edge strip continuously enters the guide groove 111 and deforms in the guide groove 111, and finally adheres to two sides of the sheet body. Finally, the edge sealing and the sheet body enter the second welding mechanism 112, and the edge covering process is completed.

The process of folding the ear belt is realized by guide board 10, and guide board 10 specifically is the board of a curved surface or crooked steel wire, and the face that guide board 10 and ear belt contact becomes the working face, and for the convenience of description, the one end that will guide board 10 is close to deflector 8 becomes the input, and the other end is called the output. In the direction by input to output, the distance between the working face of guide board 10 and the lamellar body tends to reduce, like this when the ear strap with the contact back of the working face of guide board 10, the ear strap can take place deformation gradually along with guide board 10, finally laminate on the lamellar body.

The length direction of the guide plate 10 extends along the advancing direction of the sheet body, and the ear belt is always pressed on the sheet body before the mask is discharged.

Because of the friction force between the ear belt and the guide plate 10, after the ear belt slides on the guide plate 10 and is gradually attached to the sheet body, the welding point of the ear belt is not right opposite to the edge of the sheet body needing to be covered, so that the ear belt after being covered is fixed on the sheet body in an initial inclined mode, and finally the mask produced does not meet the use requirement.

Referring to fig. 7, the correcting mechanism is composed of a second support 12, a plurality of pressing wheels 13 and a seventh driving device 14, the second support 12 is fixed on the workbench 1, the second support 12 is located between the first support 2 and the edge covering mechanism 11 in the advancing direction of the sheet body on the workbench 1, the pressing wheels 13 are provided with a plurality of pressing wheels and are all connected with the second support 12 in a rotating manner, and the seventh driving device 14 is fixedly installed on the second support 12 and used for driving the pressing wheels 13 to rotate.

In a possible embodiment, the seventh driving device 14 may be composed of a servo motor, a driving wheel connected to an output end of the servo motor, a driven wheel coaxially fixed to one of the pressing wheels 13 through a transmission shaft, and a synchronous belt sleeved outside the driving wheel and the driven wheel, wherein when the servo motor rotates, the synchronous belt drives the driven wheel and further drives one of the pressing wheels 13 to rotate.

In the process of welding the ear belts, the pressing wheel 13 driven by the seventh driving device 14 is abutted against one end, close to the advancing direction of the sheet body, of the ear belts on the sheet body, at the moment, the seventh driving device 14 drives the pressing wheel 13 to rotate, and the pressing wheel 13 is used for righting the ear belts when rotating.

Referring to fig. 6, the edge covering mechanism 11 is composed of two parts, which are respectively a guide groove 111 fixed on the workbench 1 and a second welding mechanism 112 fixed on the workbench 1, the guide groove 111 is used for wrapping the edge of the sheet body by the edge sealing, and the second welding mechanism 112 is used for welding the edge sealing and the sheet body together. In one possible embodiment of the present application, the second welding mechanism 112 also employs an ultrasonic welding machine.

Referring to fig. 1 and 7, because ultrasonic welding machine pressurizes the edge of lamellar body in welding process, easily lead to the lamellar body to take place the dislocation, in order to compress tightly the lamellar body, fixed mounting has third support 16 on the workstation 1, it is connected with a plurality of pinch rollers 17 to rotate on the third support 16, along the direction of advance of lamellar body on workstation 1, pinch roller 17 is located behind the mechanism 11 of borduring, there is the gap between pinch roller 17 and the workstation 1, this gap is less than the thickness of lamellar body.

Because pinch roller 13 and pinch roller 17 are itself great to the frictional force of lamellar body, consequently cover a plurality of pinch rollers 13 and pinch roller 17 simultaneously through belt 18 and establish, when the lamellar body motion, seventh drive arrangement 14 rotates with one of them pinch roller 13 of the rotational speed drive the same with lamellar body forward speed to make belt 18 also take place to rotate, produce too big frictional force when avoiding compressing tightly the lamellar body. When the blade stops moving during welding, the seventh drive 14 remains rotating, thereby setting the ear band upright and the seventh drive 14 is deactivated before the blade moves.
