Description

Technical Field

[0001] The present invention relates to the field of textile machinery and equipment, and in particular to a mask production device and method. Background Art

[0002] A mask is a sanitary product, generally worn on the mouth and nose to filter the air entering the mouth and nose, so as to prevent harmful gases, odors, and droplets from entering and exiting the wearer's mouth and nose. Masks have a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent, or when working in a dusty and other polluted environment, wearing a mask has a very good protective effect.

[0003] In order to enhance the protective effect of the mask, a long metal strip (such as an aluminum strip) can be added to the mask as a nose strip, so that the mask can fit closely to the nose bridge and prevent unfiltered air from entering the mouth and nose through the gap in the nose bridge.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0041] like Figures 1 to 4 As shown, a mask production device 10 according to an embodiment of the present invention includes a mask body production device and a nose bridge strip installation device 500.

[0042] like Figure 2 and Figure 3 As shown, the mask body production device includes an edge binding workbench 110, an edge binding puller 130 and a sewing mechanism 140.

[0043] The hemming workbench 110 has an hemming area.

[0044] The edge binding pull cylinder 130 is disposed on the edge binding workbench 110 and close to the edge binding area. The edge binding pull cylinder 130 is used to fold the bundle and wrap the side edge of the cover cloth to be processed to form the edge binding cover cloth.

[0045] The sewing mechanism 140 is disposed on the hemming workbench 110, and is used to sew the side of the hemming cover cloth, that is, to sew the hemming strap and the hemming cover cloth, so that the strap forms a bridge sleeve for accommodating the nose bridge bar, thereby forming the hemming mask body. Figure 2 As shown, the sewing head of the sewing mechanism 140 is close to the hemming pull cylinder 130, and sewing is performed at the hemming pull cylinder 130.

[0046] The nose bridge strip adding device 500 is used to add the nose bridge strip to the bridge sleeve to obtain the bridge-mounted mask body.

[0047] like Figure 4 As shown, in one example, the nose bridge strip installation device 500 includes a bridge installation workbench 510, a nose bridge strip guide 520, a fixing mechanism, and a pushing mechanism.

[0048] The nose bridge guide 520 is disposed on the beam mounting workbench 510. The nose bridge guide 520 has a guide channel for placing the nose bridge, and the guide channel extends along the first direction. There is a insertion gap 511 between one end of the nose bridge guide 520 and the beam mounting workbench 510, and the insertion gap 511 is used for the beam mounting sleeve on the mask body 5000 to be inserted.

[0049] The fixing mechanism is arranged on the beam-mounting workbench 510 . The fixing mechanism comprises a pressing driver 531 and a cloth pressing member 532 connected to the pressing driver 531 . The pressing driver 531 can drive the cloth pressing member 532 to press down to press the mask body placed on the beam-mounting workbench 510 .

[0050] The pushing mechanism is arranged on the beam-mounting workbench 510. The pushing mechanism includes a pushing driver 541 and a pushing member 542 connected to the pushing driver 541. The pushing member 542 extends into the guide channel and can move along the guide channel under the drive of the pushing driver 541 to push the nose bridge strip 6000 placed in the guide channel to obtain the beam-mounting mask body.

[0051] When the nose bridge strip installation device 500 is working, the bridge sleeve on the mask body 5000 is inserted into one end of the nose bridge strip guide 520, and the downward pressing driver 531 drives the cloth pressing member 532 to press down to press the mask body placed on the beam installation workbench 510 to fix the position of the mask body, and the push driver 541 drives the push member 542 to move along the guide channel to push the nose bridge strip 6000 in the guide channel into the bridge sleeve. The cloth pressing member 532 rises and the mask can be removed. Compared with manually installing the nose bridge strip, the operation difficulty is reduced and the production efficiency is improved.

[0052] like Figure 2 As shown, in one example, the mask body production device further includes a material roll rack 120, on which a plurality of material roll shafts 150 and a plurality of tension shafts 160 are arranged. The plurality of material roll shafts 150 are used to place the material rolls of the cover cloth to be processed, and the plurality of tension shafts 160 are used to guide the cover cloth to be processed on the plurality of material roll shafts 150 to the hemming area. Figure 3 The figure shows the state where both sides of the cover cloth to be processed are bound by binding strips to form a bound cover cloth 4000.

[0053] like Figure 2 As shown, in one example, there are two edge pullers 130, which are respectively arranged at opposite sides of the edge binding area to fold the binding strips and wrap the two side edges of the cover cloth to be processed. In this example, there are also two sewing mechanisms 140, which are respectively used to sew the two side edges of the edge binding cover cloth.

[0054] In the specific example shown in the figure, the two hemming pullers 130 are staggered in the direction in which the fabric tape moves in the hemming area, and correspondingly, the two sewing mechanisms 140 are staggered in this direction.

[0055] like Figure 3 As shown, in one example, the mask production equipment 10 also includes a cloth edge detector 170, a blowing nozzle (not shown) and a controller (not shown). The cloth edge detector 170 and the blowing nozzle are arranged near the cloth pressing shaft 162. The cloth edge detector 170 and the blowing nozzle are electrically connected to the controller respectively. The cloth edge detector 170 is used to detect whether the cloth edge of the cover cloth to be processed exceeds the hemming area, and the blowing nozzle is used to blow air into the hemming area. When the cloth edge detector 170 detects that the cloth edge of the cover cloth to be processed exceeds the hemming area, the controller controls the blowing nozzle to blow air.

[0056] This example specifically addresses the problem of knitted fabrics being easily misaligned due to their large shrinkage. A fabric edge detector 170 and a blow nozzle are provided to correct the misalignment of the knitted fabrics by blowing air, thereby avoiding product quality problems.

[0057] In one example, the fabric edge detector 170 is a photoelectric sensor.

[0058] like Figure 2 As shown, in one example, the tension shaft 160 includes a single-purpose shaft 161 and a cloth pressing shaft 162. There are multiple single-purpose shafts 161, and each single-purpose shaft 161 is used to change the running direction of a cover cloth to be processed. The cloth pressing shaft 162 is arranged close to the table surface of the edging area and a cloth passing gap is provided between the table surface. The cloth passing gap is used to gather multiple cloth tapes on the table surface of the edging area.

[0059] In one example, the material reel 150 includes a knitted fabric reel, a non-woven fabric reel and a woven fabric reel, wherein the non-woven fabric reel is disposed between the knitted fabric reel and the woven fabric reel. The knitted fabric reel is used to place a knitted fabric roll 1000, the non-woven fabric reel is used to place a non-woven fabric roll 2000, and the woven fabric reel is used to place a woven fabric roll 3000.

[0060] like Figure 2 As shown, in one example, there are two nonwoven fabric reels and two woven fabric reels, the two nonwoven fabric reels are arranged side by side, and the two woven fabric reels are arranged side by side.

[0061] In the specific example shown in the figure, two woven fabric reels are arranged side by side in the vertical direction, and the setting height of the two woven fabric reels is substantially the same as the height of the cloth pressing shaft 162. Two non-woven fabric reels and one knitted fabric reel are both located above the cloth pressing shaft 162 and arranged side by side in the horizontal direction.

[0062] In one example, the mask production equipment 10 also includes a roll detector (not shown) and an alarm (not shown), the roll detector and the alarm are electrically connected to the controller respectively, the roll detector is used to detect whether the remaining roll material placed on the roll shaft 150 is too little, when the roll detector detects that the remaining roll material is too little, the controller controls the alarm to sound an alarm to remind the operator. The operator can tear off the remaining cloth on the roll shaft 150 and tear off one end of the cloth tail, and splice it with the cloth head of the new roll on another roll shaft 150 with double-sided tape, the opened cloth can be used for the machine to continue sewing, thereby reducing the number of shutdowns and improving production efficiency.

[0063] In one example, the mask body production equipment further includes a strip feeding mechanism (not shown), which is used to convey the strips to the edge wrapping pull tube 130 .

[0064] The strip feeding mechanism is arranged on the hemming workbench 110 and close to the hemming pull tube 130. The strip feeding mechanism comprises a strip frame, a first cloth feeding wheel, a second cloth feeding wheel and a first rotating driver. The strip frame is used to set the strip material roll, the first cloth feeding wheel and the second cloth feeding wheel are arranged opposite to each other and the wheel surfaces are in contact with each other, and the first rotating driver is used to drive the first cloth feeding wheel and the second cloth feeding wheel to rotate in opposite directions. The first cloth feeding wheel and the second cloth feeding wheel rotate in opposite directions, so that the strips between the contacting wheel surfaces are conveyed by friction.

[0065] In one example, the mask body production equipment further includes a conveying mechanism (not shown), which is disposed on the hemming workbench 110 and is used to drive the hemmed mask body through the hemming area. The conveying mechanism drives the material roll on the material roll shaft 150 to rotate and output the cloth tape, and no human traction is required, so that the machine can be automatically operated.

[0066] In one example, the conveying mechanism is a differential feed dog. The differential feed dog can be disposed on the sewing mechanism 140, and the sewing mechanism 140 feeds the cloth while sewing.

[0067] In another example, the conveying mechanism includes a third cloth feeding wheel, a fourth cloth feeding wheel and a second rotation driver, the third cloth feeding wheel and the fourth cloth feeding wheel are arranged opposite to each other and the wheel surfaces are in contact, and the second rotation driver is used to drive the third cloth feeding wheel and the fourth cloth feeding wheel to rotate in opposite directions. In this example, in the conveying direction of the hemmed mask body, the tape cutting mechanism 400 is located downstream of the sewing mechanism 140, and relies on friction to drive the cloth tape to move.

[0068] like Figure 1 As shown, in one example, the mask body production device also includes a pleating mechanism 200. In the conveying direction of the sewing tape, the pleating mechanism 200 is located downstream of the sewing mechanism 140. The sewing tape is pleated by the pleating mechanism 200 to obtain a pleated mask body.

[0069] Furthermore, in one example, the mask body production device further includes a press 300, and the press 300 is located downstream of the pleating mechanism 200. The pleated mask body is shaped by the press 300.

[0070] like Figure 1 As shown, in one example, the mask body production device further includes a tape cutting mechanism 400, which is disposed on the hemming workbench 110, and is located downstream of the pleating mechanism 200. The tape cutting mechanism 400 is used to cut the pleated mask body into segments to obtain a slit mask body. The tape cutting mechanism 400 can use a hot knife to cut the pleated mask body.

[0071] In one example, the nose bridge guide 520 is a tube. The pusher 542 is a rod, extending into an opening at one end of the nose bridge guide 520 to push the nose bridge out of the opening at the other end.

[0072] In the specific example shown in the figure, the nose bridge bar guide 520 is a groove body with an upper opening. Similarly, the pusher 542 is a rod-shaped, extending into an opening at one end of the nose bridge bar guide 520, and pushing the nose bridge bar 6000 out from the opening at the other end. Furthermore, the upper opening of the groove body is designed to be rounded to avoid scratching the bridge sleeve.

[0073] In the specific example shown in the figure, the pressing driver 531 is a telescopic cylinder, and the pushing driver 541 is a telescopic cylinder.

[0074] like Figure 4 As shown, in one example, the nose bridge strip device 500 further includes a support member, which is disposed on a beam installation workbench 510 and supports a nose bridge strip guide member 520 to form an insertion gap 511.

[0075] In one example, the height of the insertion gap 511 is 1 mm to 2 mm. In some specific examples, the height of the insertion gap 511 is 1.2 mm, 1.5 mm, 1.7 mm, or 1.9 mm.

[0076] like Figure 4 As shown, in one example, the nose bridge strip device 500 further includes a moving mechanism, which includes a moving driver 551 and a moving member 552 connected to the moving driver 551, and the moving driver 551 can drive the moving member 552 to move along a first direction, and the moving member 552 is connected to the pressing driver 531. In this way, the operator only needs to place the mask body at the design position of the beam installation workbench 510, and the pressing driver 531 drives the cloth pressing member 532 to press down the edged mask body placed on the beam installation workbench 510, and the moving driver 551 drives the moving member 552 to move along the first direction to move the edged mask body toward the nose bridge strip guide 520, so that the beam set is inserted into the end of the nose bridge strip guide 520, and after the nose bridge strip is installed, the moving driver 551 drives the moving member 552 to move in the opposite direction to move the edged mask body away from the nose bridge strip guide 520, and the cloth pressing member 532 rises, and the mask can be removed, without manual insertion and removal, etc., further improving the degree of automation.

[0077] In the specific example shown in the figure, the mobile driver 551 is arranged below the beam installation workbench 510, and the mobile member 552 is arranged above the beam installation workbench 510. The beam installation workbench 510 is provided with a clearance hole 512, and the mobile driver 551 is connected to the mobile member 552 through the clearance hole 512.

[0078] In the specific example shown in the figure, the moving actuator 551 is a telescopic cylinder.

[0079] like Figure 4 As shown, in one example, the moving mechanism also includes a pad 553, which is connected to the moving member 552 and abuts against the beam installation workbench 510, and the cloth pressing member 532 is located between the nose bridge guide 520 and the pad 553.

[0080] like Figure 6As shown, in one example, the mask production equipment 10 also includes an edge sewing and ear hanging rope device 600, and the edge sewing and ear hanging rope device 600 includes a rope sewing workbench 610, a positioning component, a shoveling and folding component and a sewing component 650.

[0081] The rope sewing workbench 610 is provided with a mask body placement slot 611. The mask body placement slot 611 is used for placing the beam-mounted mask body 7000 for hemming and sewing the ear rope 8000. When the beam-mounted mask body 7000 is placed in the mask body placement slot 611, the two opposite sides of the beam-mounted mask body 7000 in the second direction (i.e., the two sides of the stopper to be sealed and the two sides of the ear rope sewing) extend out of the slot, and the two sides respectively form a stopper of a certain width.

[0082] The side position component is arranged on the sewing rope workbench 610. The side position component includes a side position driver and a side position plate 621 connected to the side position driver. The side position driver can drive the side position plate 621 to press into the mask body placement groove 611, thereby pressing the mask body placed in the mask body placement groove 611.

[0083] When the side plate 621 is pressed into the mask body placement groove 611, the two opposite sides of the side plate 621 in the second direction are close to the two opposite inner walls of the mask body placement groove 611 in the second direction, exposing the two side stops of the mask body.

[0084] The shoveling and folding assembly includes a first shoveling and folding component and a second shoveling and folding component. The first shoveling and folding component and the second shoveling and folding component are arranged on the rope sewing workbench 610 and are located on two opposite sides of the mask body placement groove 611 in the second direction.

[0085] The first shovel folding component includes a first shovel folding driver 631 and a first shovel folding plate 632 connected to the first shovel folding driver 631. The first shovel folding driver 631 can drive the first shovel folding plate 632 to extend toward the mask body placement slot 611 along the second direction. The first shovel folding plate 632 is provided with a first ear hanging rope fixing member 641. When working, the two ends of the ear hanging rope 8000 are placed on the corresponding side stopper, and the remaining part of the ear hanging rope 8000 is placed on the first shovel folding plate 632, and the ear hanging rope 8000 is fixed by the first ear hanging rope fixing member 641 on the first shovel folding plate 632. When the first shovel folding plate 632 extends toward the mask body placement slot 611 along the second direction, the first shovel folding plate 632 folds the exposed stopper and the end of the ear hanging rope on the stopper onto the side plate 621.

[0086] The second shoveling and folding component includes a second shoveling and folding driver 633 and a second shoveling and folding plate 634 connected to the second shoveling and folding driver 633. The second shoveling and folding driver 633 can drive the second shoveling and folding plate 634 to extend toward the mask body placement slot 611 along the second direction. The second shoveling and folding plate 634 is provided with a second ear hanging rope fixing member 642. Similarly, when the second shoveling and folding plate 634 extends toward the mask body placement slot 611 along the second direction, the second shoveling and folding plate 634 folds the exposed stop and the ear hanging rope end on the stop onto the side plate 621.

[0087] After the two side stops of the mask body are folded, the side plate 621 is pulled out from the mask body, and can be used for sewing equipment to sew the stops subsequently. At the same time, since the ends of the ear ropes are folded in the stops, the ear ropes on both sides can be sewn to the mask body while sewing the stops.

[0088] The sewing component 650 is arranged on the rope sewing workbench 610, and the sewing component 650 is used to sew the stopper position. More specifically, the sewing component 650 can sew along the third direction. In the present invention, the second direction and the third direction are two directions perpendicular to each other on the horizontal plane.

[0089] In one example, the first ear strap fixing member 641 and / or the second ear strap fixing member 642 is a spring clip.

[0090] In the specific example shown in the figure, both the first ear hanging rope fixing member 641 and the second ear hanging rope fixing member 642 are spring clips. The first shovel folding plate 632 is provided with two first ear hanging rope fixing members 641 arranged in the third direction, and the second shovel folding plate 634 is provided with two second ear hanging rope fixing members 642 arranged in the third direction.

[0091] In the specific example shown in the figure, the first shovel-folding driver 631 and the second shovel-folding driver 633 are both telescopic cylinders.
