The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0041] Please refer to Figure 1 and Figure 2 As shown, a mask production device 10 according to an embodiment of the present invention includes a machine base 101, a side seam ear hanging rope device 100, a side folding device 200, and a conveying device 400. The side seam ear hanging rope device 100, the side folding device 200, and the conveying device 400 are all arranged on the machine base 101.

[0042] The machine base 101 is provided with a rope sewing platform 111 for placing the masks to be processed.

[0043] The edge-seaming ear rope device 100 includes a pressing and rotating mechanism 120 and a sewing mechanism 130 .

[0044] The pressing and rotating mechanism 120 is arranged on the machine base 101. The pressing and rotating mechanism 120 includes a pressing driver 121, a rotating driver 122 and a cloth pressing member 123. The pressing driver 121 is connected to the cloth pressing member 123 and can drive the pressing member to press the mask to be processed on the sewing rope platform 111. The rotating driver 122 is connected to the cloth pressing member 123 and can drive the cloth pressing member 123 to rotate.

[0045] The sewing mechanism 130 is arranged on the machine base 101. The sewing mechanism 130 is used to sew the mask to be processed.

[0046] The conveying device 400 is used to convey the sewn string mask to the folding device 200. The folding device 200 is used to fold the two ends of the sewn string mask to obtain a folded mask.

[0047] When using the above-mentioned mask production equipment 10 to produce masks, the mask body is placed on the sewing platform 111, and ear hanging ropes are placed on the first and second ends of the mask body respectively to form a mask to be processed. The downward pressure driver 121 drives the cloth pressing member 123 to press the mask to be processed, and the sewing mechanism 130 sews the first end to complete the edge sealing and sewing of the ear hanging ropes at the first end. Then, the rotary driver 122 drives the cloth pressing member 123 to rotate so that the second end rotates to the sewing mechanism 130. The sewing mechanism 130 sews the second end to complete the edge sealing and sewing of the ear hanging ropes at the second end. The conveying device 400 conveys the sewn mask to the folding device 200. The folding device 200 folds the two ends of the sewn mask to obtain a folded mask. The above-mentioned mask production equipment 10 can realize the automated production of masks, save manpower, and improve production efficiency.

[0048] like Figure 2 As shown, in one example, the sewing platform 111 has a placement station 1112 and a sewing station 1114. The placement station 1112 is used to place the masks to be processed. The downward pressing rotary mechanism 120 is movably connected to the machine base 101 and can move between the placement station 1112 and the sewing station 1114. In this example, the downward pressing driver 121 can drive the downward pressing member to press on the placement station 1112. After the downward pressing member presses the mask to be processed, it is transferred to the sewing station 1114, and the sewing mechanism 130 sews the mask to be processed on the sewing station 1114.

[0049] Furthermore, in one example, the sewing platform 111 also has a side-changing station, and the downward-pressing rotary mechanism 120 is also capable of moving between the sewing station 1114 and the side-changing station. In this example, after the sewing mechanism 130 has completed sewing the first end, the downward-pressing rotary mechanism 120 transfers the mask to be processed, which has already been sewn on the first end, to the side-changing station. The rotary driver 122 drives the cloth pressing member 123 to rotate in the side-changing station. After the side-changing is completed, the mask to be processed, which has already been sewn on the first end, is then transferred back to the sewing station 1114 for sewing on the second end. This example can solve the problem of inconvenient side-changing in the sewing station 1114.

[0050] Furthermore, in one example, the rope sewing platform 111 also has a material receiving station, and the downward pressing rotating mechanism 120 can transfer the rope sewing mask with completed edge sealing and ear hanging ropes to the material receiving station.

[0051] like Figure 3 As shown, in one example, the downward pressing rotation mechanism 120 also includes a mounting seat 124, the mounting seat 124 is movably connected to the machine base 101, the downward pressing driver 121 is connected to the mounting seat 124, the rotation driver 122 is connected to the downward pressing driver 121, and the downward pressing driver 121 is used to drive the rotation driver 122 and the cloth pressing member 123 to rise or fall as a whole.

[0052] In the illustrated embodiment, the downward-pressing rotation mechanism 120 further includes a connecting member 125, which includes a first mounting plate 1251, a second mounting plate 1252, and a third mounting plate 1253. The first mounting plate 1251 is connected to the downward-pressing driver 121, while the second and third mounting plates 1252, 1253 are respectively connected to the ends of the first mounting plate 1251. The first, second, and third mounting plates 1251, 1252, 1253 form a mounting space. The rotation driver 122 is a rotary motor. The second mounting plate 1252 has a second mounting hole. The rotation driver 122 is mounted above the second mounting plate 1252, with its output shaft extending into the mounting space. The third mounting plate 1253 has a third mounting hole. The cloth pressing member 123 is provided with a connecting shaft 126. The cloth pressing member 123 is positioned below the third mounting plate 1253. The connecting shaft 126 passes through the third mounting hole, extends into the mounting space, and is connected to the output shaft of the rotation driver 122. The connecting shaft 126 is connected to the output shaft of the rotary driver 122 in the installation space via a coupling 127. A mounting bearing 128 is also provided on the third mounting plate 1253, through which the connecting shaft 126 passes and is connected to the output shaft of the rotary driver 122.

[0053] like Figure 2As shown in one example, the edge-seamed ear hook device 100 further includes a guide member 141, with the mounting base 124 slidably engaged with the guide member 141. The guide member 141 can be a guide rail. More specifically, the guide member 141 is equipped with a moving motor 142 and a moving base 143. The moving motor 142 drives the moving base 143 to move on the guide member 141. The mounting base 124 is connected to the moving base 143 to achieve the aforementioned movable connection.

[0054] like Figure 2 As shown, in one example, the placement station 1112 is provided with an air suction hole. The air suction hole can fix the folds of the mask body by suction, and fix the position of the mask body and the ear hanging rope.

[0055] In the specific example shown in the figure, the suction holes are distributed in an array on the sewing station 1114.

[0056] In one example, the edge-sealed ear rope device 100 further includes a fan 150 , which is connected to the air suction hole. The fan 150 is used to form negative pressure and suck air from the air suction hole.

[0057] like Figure 2 As shown, in one example, the edge-seaming ear rope device 100 further includes a positioning mechanism 160, which is arranged around the placement station 1112 and is used to limit the placement position of the mask to be processed so that the subsequent sewing mechanism 130 can sew accurately.

[0058] In the illustrated example, the placement station 1112 is a rectangular area corresponding to the mask body. The positioning mechanism 160 includes three positioning bars, one of which is located along the three sides of the rectangular area. One side of the placement station 1112 is open, i.e., there are no positioning bars, to facilitate the removal of the mask to be processed from the placement station 1112.

[0059] like Figure 2 As shown, in one example, the edge seam ear rope device 100 further includes a yarn rack 170 , which is disposed on the machine base 101 and is used to place yarn for sewing.

[0060] like Figure 4 As shown, in one example, the folding device 200 includes a folding base and a folding assembly.

[0061] The folding assembly includes a folding station plate 221 , a folding plate 222 and a folding driver 223 .

[0062] The hemming station plate 221 is arranged on the hemming base 210. The hemming station plate 221 is provided with a first plate surface and a second plate surface opposite to the first plate surface. The first plate surface is used for placing the sewing mask.

[0063] The folding plate 222 is disposed at the edge of the hemming station plate 221, and a hemming gap 224 is defined between the folding plate 222 and the first panel for inserting the sewing mask. A folding driver 223 is connected to the folding plate 222 and is capable of driving the folding plate 222 to flip around the edge of the hemming station plate 221 from the first panel to the second panel, thereby folding the portion of the sewing mask that extends beyond the edge of the hemming station plate 221 onto the second panel.

[0064] When using the hemming device 200 for hemming, a mask with a cord is placed on the first surface of the hemming station plate 221. The portion of the mask extending beyond the edge of the hemming station plate 221 passes through the hemming gap 224. The folding driver 223 is controlled to drive the folding plate 222 to flip around the edge from the first surface to the second surface, thereby folding the portion of the mask extending beyond the edge onto the second surface. The hemming device 200 improves the automation level of hemming of cut pieces, saves manpower, and improves production efficiency.

[0065] In one example, in the unfolded state, the folding plate 222 is perpendicular to the hemming station plate 221. In this example, in the unfolded state, a hemming gap 224 is formed between the lower end of the folding plate 222 and the first plate surface of the hemming station plate 221.

[0066] like Figure 4 As shown, in one example, the edges of the opposite ends of the folding station plate 221 are respectively provided with folding plates 222. In this way, in the mask production process, the two ends of the mask can be automatically folded.

[0067] In one example, the folding driver 223 is a motor, and the rotation shaft of the folding driver 223 is connected to one end of the folding plate 222. The folding plate 222 is a strip plate, and its extension direction is parallel to the edge position of the folding station plate 221.

[0068] like Figure 4 As shown, in one example, the folding assembly further includes an origin sensor 225 , which is electrically connected to the folding driver 223 to control the angle at which the folding driver 223 drives the folding plate 222 to flip.

[0069] like Figure 4 As shown, in one example, the hemming base 210 has a rotary drive 212, which is connected to the hemming assembly. The rotary drive 212 can drive the hemming assembly to rotate to change the position of the hemming assembly. In this example, when the hemming is completed, the rotary drive 212 can drive the hemming assembly to rotate, making it easier to transport the hemmed piece to the next process.

[0070] In one example, the rotary actuator 212 is a rotary cylinder.

[0071] Furthermore, in one example, a plurality of hemming assemblies are provided on the hemming base 210. In this example, after one hemming assembly completes hemming a piece, the rotary driver 212 can drive the hemming assembly to rotate, transporting the hemmed piece to the next process, while simultaneously rotating the idle hemming assembly back to fold the next piece.

[0072] In the specific example shown in the figure, two folding components are provided on the folding base 210, and the two folding components are arranged in back-to-back directions.

[0073] Furthermore, the present invention also provides a folding method, which uses the folding device 200 of any of the above examples or the mask production equipment 10 of any of the above examples, and includes the following steps:

[0074] Place the sewing mask on the first plate surface of the folding station plate 221, and the portion of the sewing mask that exceeds the edge of the folding station plate 221 passes through the folding gap 224;

[0075] The folding driver 223 is controlled to drive the folding plate 222 to flip around the edge position from the first plate surface to the second plate surface, so as to fold the portion of the seam mask exceeding the edge position to the second plate surface.

[0076] like Figure 1 and Figure 5 As shown in one example, the mask production equipment 10 further includes a cord hooking device 300, which is mounted on the machine base 101 and downstream of the hemming device 200. The cord hooking device 300 includes a cord hooking base 310, a first-direction telescopic actuator 320, a second-direction telescopic actuator 330, and a cord hooking member 340. The first-direction telescopic actuator 320 is mounted on the cord hooking base 310, the second-direction telescopic actuator 330 is connected to the first-direction telescopic actuator 320, and the cord hooking member 340 is connected to the second-direction telescopic actuator 330. The first-direction telescopic actuator 320 is capable of driving the second-direction telescopic actuator 330 and the cord hooking member 340 to move in a first direction, while the second-direction telescopic actuator 330 is capable of driving the cord hooking member 340 in a second direction, with the first direction being perpendicular to the second direction. The operation of the first-direction telescopic actuator 320 and the second-direction telescopic actuator 330 causes the cord hooking member 340 to be inserted under the ear hook in the first direction and then to be hooked away from the mask body in the second direction. This makes it easier to carry out the subsequent sewing work.

[0077] In the specific example shown in the figure, the mask production equipment 10 includes two opposite hooking devices 300, which are used to hook and unhook the ear hanging ropes at both ends.

[0078] like Figure 1 As shown, in one example, the mask production equipment also includes a conveying device 400 and a spacing device 500. The conveying device 400 is used to convey the hook-string mask that has completed the hook-string process to the spacing device 500, and the spacing device 500 is used to sew spacing lines at the folding position of the hook-string mask.

[0079] Furthermore, the present invention also provides a mask production method, using the edge-sealed ear-hanging rope device 100 of any of the above examples or the mask production equipment 10 of any of the above examples, the mask production method includes the following steps:

[0080] Place the mask body on the rope sewing platform 111, and place ear hanging ropes on the first end and the second end of the mask body respectively to form a mask to be processed;

[0081] Control the pressing driver 121 to drive the cloth pressing member 123 to press the mask to be processed;

[0082] Controlling the sewing mechanism 130 to sew the first end;

[0083] Controlling the rotary driver 122 to drive the cloth pressing member 123 to rotate so that the second end rotates to the sewing mechanism 130;

[0084] Controlling the sewing mechanism 130 to sew the second end to obtain a sewn rope mask;

[0085] Control the conveying device 400 to convey the sewn mask to the folding device 200;

[0086] The folding device 200 is controlled to fold the two ends of the sewn rope mask to obtain a folded mask.

[0087] When using the above-mentioned mask production equipment 10 to produce masks, the mask body is placed on the sewing platform 111, and ear ropes are placed on the first and second ends of the mask body respectively to form a mask to be processed. The downward pressure driver 121 drives the cloth pressing member 123 to press the mask to be processed, and the sewing mechanism 130 sews the first end to complete the edge sealing and sewing of the ear ropes at the first end. Then, the rotary driver 122 drives the cloth pressing member 123 to rotate so that the second end rotates to the sewing mechanism 130. The sewing mechanism 130 sews the second end to complete the edge sealing and sewing of the ear ropes at the second end. The conveying device 400 conveys the sewn mask to the folding device 200. The folding device 200 is used to fold the two ends of the sewn mask to obtain a folded mask. The above-mentioned mask production equipment 10 can realize the automated production of masks, save manpower, and improve production efficiency.

[0088] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0089] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
