Description

Technical Field

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

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

[0003] The main part of the mask generally uses three kinds of fabrics: shuttle-woven fabric, melt-blown non-woven fabric, and knitted fabric. The traditional manufacturing method relies on manual operation to stack the three fabric pieces in sequence and use a flatbed sewing machine to sew the four side edges, which is time-consuming and laborious, and the production efficiency is relatively low. Summary of the Invention

[0004] Based on this, it is necessary to provide a mask production device and method to improve the mask production efficiency.

[0005] A mask production device includes:

[0006] A hemming workbench, which has a hemming area on it;

There are multiple single-use shafts, and each single-use shaft is used to change the running direction of a cloth tape. The cloth pressing shaft is arranged close to the table surface of the edge wrapping area and there is a cloth passing gap between the cloth pressing shaft and the table surface. The cloth passing gap is used to gather multiple cloth tapes on the table surface of the edge wrapping area.

[0014] In one embodiment, the mask production equipment further includes a cloth edge detector, a blowing nozzle, and a controller. The cloth edge detector and the blowing nozzle are arranged close to the cloth pressing shaft. The cloth edge detector and the blowing nozzle are electrically connected to the controller respectively. The cloth edge detector is used to detect whether the edge of a cloth tape exceeds the edge wrapping area, and the blowing nozzle is used to blow air towards the inside of the edge wrapping area. When the cloth edge detector detects that the edge of a cloth tape exceeds the edge wrapping area, the controller controls the blowing nozzle to blow air.

[0015] In one embodiment, the cloth edge detector is a photoelectric inductor.

[0016] In one embodiment, the mask production equipment further includes a binding strip feeding mechanism. The binding strip feeding mechanism is arranged on the edge wrapping workbench and close to the edge wrapping draw cylinder. The binding strip feeding mechanism includes a binding strip rack, a first cloth feeding wheel, a second cloth feeding wheel, and a first rotation driver.

[0033] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the accompanying drawings. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present disclosure.

[0034] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] like Figure 1 and Figure 2 As shown, a mask production device 10 according to an embodiment of the present invention includes a hemming workbench 110 , a material roll rack 120 , an hemming puller 130 , and a sewing mechanism 140 .

[0037] The hemming workbench 110 has an hemming area.

[0038] The material roll rack 120 is provided with a plurality of material roll shafts 150 and a plurality of tension shafts 160. The plurality of material roll shafts 150 are used to place the cloth tape rolls, and the plurality of tension shafts 160 are used to guide the cloth tape rolls on the plurality of material roll shafts 150 to the hemming area to form a stacked cloth tape.

[0039] The hemming pull cylinder 130 is arranged on the hemming workbench 110 and close to the hemming area. The hemming pull cylinder 130 is used to fold the bundle and wrap the side edges of the stacked cloth tapes to form the hemming cloth tapes. Figure 3 The diagram shows a state where both sides of the stacked tapes are bound by binding strips to form bound tapes 4000 .

[0040] The sewing mechanism 140 is arranged on the hemming workbench 110, and is used to sew the side edges of the hemming tape, that is, to sew the hemming strips and the stacked tapes to form sewn tapes. Figure 1 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 .

[0041] like Figure 1As shown, in one example, there are two hemming runners 130, which are respectively arranged on opposite sides of the hemming area to fold and wrap the side edges of the stacked fabric tapes. In this example, there are also two sewing mechanisms 140, which are respectively used to sew the side edges of the hemmed fabric tapes.

[0042] In the specific example shown in the figure, the two hemming runners 130 are staggered in the direction in which the fabric tape moves in the hemming area. Correspondingly, the two sewing mechanisms 140 are staggered in this direction.

[0043] As Figure 2 shown, in one example, the mask production device 10 further includes a fabric edge detector 170, a blowing nozzle (not shown in the figure), and a controller (not shown in the figure). The fabric edge detector 170 and the blowing nozzle are arranged close to the fabric pressing shaft 162. The fabric edge detector 170 and the blowing nozzle are respectively electrically connected to the controller. The fabric edge detector 170 is used to detect whether the edge of the fabric tape extends beyond the hemming area, and the blowing nozzle is used to blow air into the hemming area. When the fabric edge detector 170 detects that the edge of the fabric tape extends beyond the hemming area, the controller controls the blowing nozzle to blow air.

[0044] This example specifically addresses the problem that the knitted fabric is prone to shrinkage and displacement. The fabric edge detector 170 and the blowing nozzle are provided. When the knitted fabric is displaced, it is corrected by blowing air to avoid product quality problems.

[0045] In one example, the fabric edge detector 170 is a photoelectric inductor.

[0046] As Figure 1 shown, in one example, the tension shaft 160 includes a single-use shaft 161 and a fabric pressing shaft 162. There are multiple single-use shafts 161, and each single-use shaft 161 is used to change the running direction of a fabric tape. The fabric pressing shaft  162 is arranged close to the table surface of the hemming area and there is a fabric passing gap between it and the table surface. The fabric passing gap is used to gather multiple fabric tapes on the table surface of the hemming area.

[0047] In one example, the material reel 150 includes a knitted fabric reel, a non-woven fabric reel, and a woven fabric reel. The non-woven fabric reel is arranged between the knitted fabric reel and the woven fabric reel. The knitted fabric reel is used to place the knitted fabric roll 1000, the non-woven fabric reel is used to place the non-woven fabric roll 2000, and the woven fabric reel is used to place the woven fabric roll 3000.

[0048] As Figure 1 shown, in one example, there are two non-woven fabric reels and two woven fabric reels. The two non-woven fabric reels are arranged side by side, and the two woven fabric reels are arranged side by side.

[0049] In the specific example shown in the figure, two shuttle-woven fabric reels are arranged side by side in the vertical direction, and the installation heights of the two shuttle-woven fabric reels are approximately the same as the height of the cloth pressing shaft 162. The two non-woven fabric reels and one knitted fabric reel are all located above the cloth pressing shaft 162 and are arranged side by side in the horizontal direction.

[0050] In one example, the mask production device 10 further includes a material roll detector (not shown in the figure) and a warning device (not shown in the figure). The material roll detector and the warning device are electrically connected to the controller respectively. The material roll detector is used to detect whether the remaining material of the cloth tape roll placed on the material roll shaft 150 is too little. When the material roll detector detects that the remaining material of the cloth tape roll is too little, the controller controls the warning device to issue an alarm to remind the operator. The operator can tear out the end of the cloth tail from the remaining cloth of the cloth tape roll on the material roll shaft 150 and join it with the end of the new cloth tape roll on another material roll shaft 150 with double-sided tape. The torn cloth can be used for the machine to continue sewing, so the number of stops can be reduced and the production efficiency can be improved.

[0051] In one example, the mask production device 10 further includes a binding strip feeding mechanism (not shown in the figure), and the binding strip feeding mechanism is used to convey the binding strip to the edge binding cylinder 130.

[0052] The binding strip feeding mechanism is arranged on the edge binding workbench 110 and is close to the edge binding cylinder 130. The binding strip feeding mechanism includes a binding strip rack, a first cloth feeding wheel, a second cloth feeding wheel and a first rotation driver. The binding strip rack is used to set the binding strip material roll. The first cloth feeding wheel and the second cloth feeding wheel are arranged oppositely and the wheel surfaces are in contact. The first rotation driver is used to drive the first cloth feeding wheel and the second cloth feeding wheel to rotate towards each other. The first cloth feeding wheel and the second cloth feeding wheel rotate towards each other, so that the binding strip between the contacting wheel surfaces is conveyed by the frictional force.

[0053] In one example, the mask production device 10 further includes a conveying mechanism (not shown in the figure). The conveying mechanism is arranged on the edge binding workbench 110, and the conveying mechanism is used to drive the sewn cloth tape through the edge binding area. Through the driving of the conveying mechanism, the cloth tape roll on the material roll shaft 150 rotates to output the cloth tape, and there is no need to rely on manual traction, and the machine can run automatically.

[0054] In one example, the conveying mechanism is a differential feed dog. The differential feed dog can be arranged on the sewing mechanism 140, and the sewing mechanism 140 sews and feeds the cloth at the same time.

[0055] 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 oppositely and the wheel surfaces are in contact. The second rotation driver is used to drive the third cloth feeding wheel and the fourth cloth feeding wheel to rotate towards each other. In this example, in the conveying direction of the sewn cloth tape, the tape cutting mechanism 400 is located downstream of the sewing mechanism 140, and the cloth tape is driven to move by the frictional force.

[0056] As Figure 4 shown, in one example, the mask production device 10 further includes a pleating mechanism 200 and a press 300. In the conveying direction of the stitched fabric strip, the pleating mechanism 200 is located downstream of the sewing mechanism 140, and the press 300 is located downstream of the pleating mechanism 200. The stitched fabric strip is pleated by the pleating mechanism 200 and then shaped by the press 300.

[0057] As Figure 4 shown, in one example, the mask production device 10 further includes a tape cutting mechanism 400. The tape cutting mechanism 400 is arranged on the edge wrapping workbench 110. In the conveying direction of the stitched fabric strip, the tape cutting mechanism 400 is located downstream of the pleating mechanism 200. The tape cutting mechanism 400 is used to cut the stitched fabric strip into segments. The tape cutting mechanism 400 can use a hot knife to cut the stitched fabric strip.

[0058] As Figure 4 and Figure 5 shown, in one example, the mask production device 10 further includes a device 500 for installing the nose strip of the mask.

[0059] The device 500 for installing the nose strip of the mask includes a beam installation workbench 510, a nose strip guide 520, a fixing mechanism, and a pushing mechanism.

[0060] Among them, the nose strip guide 520 is arranged on the beam installation workbench 510. The nose strip guide 520 has a guide channel for placing the nose strip, and the guide channel extends along the first direction. There is a fitting gap 511 between one end of the nose strip guide 520 and the beam installation workbench 510, and the fitting gap 511 is used for the beam placement sleeve on the mask body 5000 to be fitted into.

[0061] The fixing mechanism is arranged on the beam installation workbench 510. The fixing mechanism includes a downward pressing driver 531 and a cloth pressing member 532 connected to the downward pressing driver 531. The downward pressing driver 531 can drive the cloth pressing member 532 to press down to press the mask body placed on the beam installation workbench 510.

[0062] The pushing mechanism is arranged on the beam installation 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 strip 6000 placed in the guide channel.

[0063] When the device 500 for adding nose bridge strips to a mask is working, the beam sleeve on the mask body 5000 is sleeved on one end of the nose bridge strip guide 520. The pressing driver 531 presses down to drive the pressing cloth member 532 to press down on the mask body placed on the beam mounting workbench 510, so as to fix the position of the mask body. The pushing driver 541 drives the pushing member 542 to move along the guiding channel, so as to push the nose bridge strip 6000 in the guiding channel into the beam sleeve. The pressing cloth member 532 rises, and the mask can be taken off. Compared with manually adding nose bridge strips, the operation difficulty is reduced and the production efficiency is improved.

[0064] In one example, the nose bridge strip guide 520 is a tube body. The pushing member 542 is rod-shaped and extends into the opening at one end of the nose bridge strip guide 520, and pushes the nose bridge strip out from the opening at the other end.

[0065] In the specific example shown in the figure, the nose bridge strip guide 520 is a groove body with an upper opening. Similarly, the pushing member 542 is rod-shaped and extends into the opening at one end of the nose bridge strip guide 520, and pushes the nose bridge strip 6000 out from the opening at the other end. Further, the upper opening of the groove body is designed with a rounded corner to avoid scratching the beam sleeve.

[0066] 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.

[0067] As Figure 5 shown, in one example, the device 500 for adding nose bridge strips to a mask further includes a support member, and the support member is arranged on the beam mounting workbench 510 and supports the nose bridge strip guide 520 to form a sleeving gap 511.

[0068] In one example, the height of the sleeving gap 511 is 1 mm to 2 mm. In some specific examples, the height of the sleeving gap 511 is 1.2 mm, 1.5 mm, 1.7 mm, 1.9 mm.

[0069] As Figure 5As shown in one example, the device 500 for adding a nose bridge strip to a mask further includes a moving mechanism, comprising a moving driver 551 and a moving member 552 connected to the moving driver 551. The moving driver 551 is capable of driving the moving member 552 to move in a first direction, and the moving member 552 is connected to a downward-pressing driver 531. In this manner, an operator simply places the mask body at the designed position on the beam-mounting workbench 510. The downward-pressing driver 531 drives the cloth-pressing member 532 to press down on the mask body placed on the beam-mounting workbench 510. The moving driver 551 drives the moving member 552 to move in the first direction toward the nose bridge strip guide 520, thereby inserting the nose bridge strip sleeve into the end of the nose bridge strip guide 520. After the nose bridge strip is installed, the moving driver 551 drives the moving member 552 to move in the opposite direction, moving the mask body away from the nose bridge strip guide 520. The cloth-pressing member 532 then rises, and the mask can be removed. This eliminates the need for manual insertion and removal operations, further improving the degree of automation.

[0070] In the specific example shown in the figure, the mobile driver 551 is arranged below the beam installing workbench 510, and the moving part 552 is arranged above the beam installing workbench 510. A clearance hole 512 is provided on the beam installing workbench 510, and the mobile driver 551 is connected to the moving part 552 through the clearance hole 512.

[0071] In the specific example shown in the figure, the moving driver 551 is a telescopic cylinder.

[0072] like Figure 5 As shown, in one example, the moving mechanism also includes a pad 553, which is connected to the moving part 552 and rests on the beam installation workbench 510, and the cloth pressing part 532 is located between the nose bridge guide 520 and the pad 553.

[0073] like Figure 4 and Figure 6 As shown, in one example, the mask production equipment 10 also includes an ear rope sewing device 600.

[0074] The ear rope sewing device 600 includes a rope sewing workbench 610, a positioning mechanism, a shoveling and folding assembly, and a sewing mechanism 650.

[0075] The string sewing workbench 610 is equipped with a mask body placement slot 611. This slot 611 accommodates the mask body 7000 to be processed for hemming and sewing the ear string 8000. When the mask body 7000 is placed in the slot 611, two opposing sides of the mask body 7000 in the second direction (i.e., the side to be sealed and the side where the ear string is sewn) extend out of the slot, forming a stopper of a certain width on each side.

[0076] The side-positioning mechanism is arranged on the sewing cord workbench 610. The side-positioning mechanism includes a side-positioning driver and a side-positioning plate 621 connected to the side-positioning driver. The side-positioning driver can drive the side-positioning plate 621 to press into the mask body placement groove 611, so as to press the mask body placed in the mask body placement groove 611.

[0077] When the side-positioning plate 621 presses into the mask body placement groove 611, the two opposite sides of the side-positioning plate 621 in the second direction are close to the inner walls of the two opposite sides of the mask body placement groove 611 in the second direction, exposing the two side hemmings of the mask body.

[0078] The shoveling and folding assembly includes a first shoveling and folding mechanism and a second shoveling and folding mechanism. The first shoveling and folding mechanism and the second shoveling and folding mechanism are arranged on the sewing cord workbench 610 and are located on the two opposite sides of the mask body placement groove 611 in the second direction.

[0079] The first shoveling and folding mechanism includes a first shoveling and folding driver 631 and a first shoveling and folding plate 632 connected to the first shoveling and folding driver 631. The first shoveling and folding driver 631 can drive the first shoveling and folding plate 632 to extend towards the mask body placement groove 611 in the second direction. A first earloop fixing member 641 is arranged on the first shoveling and folding plate 632. During operation, the two ends of the earloop 8000 are placed on the corresponding side hemmings, and the remaining part of the earloop 8000 is placed on the first shoveling and folding plate 632, and the earloop 8000 is fixed by the first earloop fixing member 641 on the first shoveling and folding plate 632. When the first shoveling and folding plate 632 extends towards the mask body placement groove 611 in the second direction, the first shoveling and folding plate 632 folds the exposed hemming and the end of the earloop on this hemming onto the side-positioning plate 621.

[0080] The second shoveling and folding mechanism 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 towards the mask body placement groove 611 in the second direction. A second earloop fixing member 642 is arranged on the second shoveling and folding plate 634. Similarly, when the second shoveling and folding plate 634 extends towards the mask body placement groove 611 in the second direction, the second shoveling and folding plate 634 folds the exposed hemming and the end of the earloop on this hemming onto the side-positioning plate 621.

[0081] After folding the two side hemmings of the mask body, the side-positioning plate 621 is withdrawn from the mask body, and subsequently, a sewing device can sew the hemmings. At the same time, since the ends of the earloops are folded in the hemmings, the two side earloops can be sewn onto the mask body while sewing the hemmings.

[0082] The sewing mechanism is arranged on the sewing rope workbench 610, and the sewing mechanism is used for sewing the lapel position. More specifically, the sewing mechanism 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.

[0083] In one example, the first earloop rope fixing member 641 and / or the second earloop rope fixing member 642 is a spring clip.

[0084] In the specific example shown in the figure, both the first earloop rope fixing member 641 and the second earloop rope fixing member 642 are spring clips. Two first earloop rope fixing members 641 arranged in the third direction are provided on the first folding plate 632, and two second earloop rope fixing members 642 arranged in the third direction are provided on the second folding plate 634.

[0085] In the specific example shown in the figure, both the first folding driver 631 and the second folding driver 633 are telescopic cylinders.

[0086] It can be understood that the shape and size of the mask body placement groove 611 can be designed according to the mask body to be processed. For example, if the shape of the mask body to be processed is rectangular, the mask body placement groove 611 is also rectangular. The length of the mask body placement groove 611 is slightly shorter than the length of the mask body to be processed, and the width of the mask body placement groove 611 is the same as the width of the mask body to be processed.

[0087] In one example, the depth of the mask body placement groove 611 is 2 mm to 2.5 mm, so that the subsequent side plate 621 can be smoothly withdrawn from the mask body. In some specific examples, the depth of the mask body placement groove 611 is 2.1 mm, 2.2 mm, 2.3 mm, or 2.4 mm.

[0088] As Figure 6 shown, in one example, the side plate driver includes a third direction driving component 622 and a vertical driving component 623. The vertical driving component 623 is connected to the side plate 621 to drive the side plate 621 to move in the vertical direction, and the third direction driving component 622 is connected to the vertical driving component 623 to drive the vertical driving component 623 to move in the second direction.

[0089] As Figure 6 shown, in one example, the side plate mechanism further includes a slide rail 624 and a guide member 625. The slide rail 624 extends along the third direction, and the slide rail 624 is slidably engaged with the guide member 625. The guide member 625 is respectively connected to the third direction driving component 622 and the vertical driving component 623 on the relatively two sides in the third direction.

[0090] In the specific example shown in the figure, the slide rail 624 includes a first side rail and a second side rail arranged in parallel, and the guide member 625 is a vertical plate, and the guide member 625 is arranged on the first side rail and the second side rail. In the second direction, both the third-direction driving member 622 and the vertical driving member 623 are located between the first side rail and the second side rail.

[0091] In the specific example shown in the figure, both the third-direction driving member 622 and the vertical driving member 623 are telescopic cylinders.

[0092] As Figure 1 shown, in one of the examples, the mask production device 10 further includes a hemming mechanism 700, and the hemming mechanism 700 is arranged between the nose bridge strip adding device 500 and the earloop sewing device 600. The hemming mechanism 700 includes a bone sewing machine for hemming the mask body with a beam.

[0093] Furthermore, the present invention also provides a method for producing a mask body, using the mask production device 10 of any of the above examples. The method for producing a mask body includes the following steps:

[0094] Place a plurality of cloth tape rolls on a plurality of material winding shafts 150 respectively;

[0095] Guide the plurality of cloth tape rolls to the hemming area through a plurality of tension shafts 160 to form stacked cloth tapes;
