Description

Technical Field

[0001] The present invention relates to mask production equipment, in particular to a mask machine. Background Art

[0002] A mask is a sanitary product, generally refers to a device worn on the mouth and nose to filter the air entering the mouth and nose, so as to block harmful gases, odors, viruses, and droplets from entering and exiting the wearer's mouth and nose. Masks are mainly made of non-woven fabrics and gauze. Masks have a certain filtering effect on the air entering the lungs. Wearing a mask has a very good effect when respiratory infectious diseases are prevalent and when working in an environment polluted by dust.

[0003] Existing masks are generally produced automatically using mask production equipment. The mask production equipment manufactures various masks with certain filtering performance by hot pressing, folding, ultrasonic welding, waste cutting, ear strap, nose bridge welding and other processes of multi-layer non-woven fabrics. The mask equipment is not a single machine, it requires the cooperation of multiple machines to complete various different processes; the mask includes a mask body and ear strap lines, the ear strap lines are fixed on the mask body, and the function of the ear strap lines is to fix the mask body on the user's face to achieve the effect of filtering the air.

[0004] The invention patent application with application publication number CN111169993A discloses "an ear wire conveying device for mask production", including a frame, an ear wire conveying mechanism arranged on the frame, and an ear wire clamping and conveying mechanism for clamping the ear wire conveyed by the ear wire conveying mechanism and conveying it synchronously with the mask strip to the ear wire welding station, wherein the ear wire clamping and conveying mechanism is divided into two groups, which are respectively located on both sides of the ear wire welding station, each group of ear wire clamping and conveying mechanism includes a plurality of clamping mechanisms for clamping the ear wires and an ear wire conveying driving mechanism for driving the clamping mechanisms to circulate so as to promote the synchronous movement of the ear wires and the mask strip; the mask strip passes through the top of the ear wire welding station, and the ear wire clamped by the clamping mechanism is located on the upper side of the mask strip; the ear wire conveying driving mechanism drives the plurality of clamping mechanisms to clamp the ear wires and move synchronously with the mask strip.

[0005] However, the ear wire delivery device for mask production described above has the following shortcomings:

[0006] like Figure 1As shown, for duckbill-shaped masks and head-mounted masks, since the ear wires move synchronously with the mask strips, the above-mentioned device can only produce masks with the same ear strap length and mask opening width, because the ear strap wires can only be clamped in the upper and lower layers of the mask in an approximately straight shape, so the length of the ear strap wire is consistent with the length of the material strip, and the ear strap wire is pressed in as much as the length of the material strip is conveyed. When the material strip is cut into sections to produce masks one by one, the length of the ear strap wire in each mask is the opening width of the mask. Therefore, the above-mentioned device cannot produce masks with ear strap wires longer than the width of the mask opening, and it is even more impossible to control the length of the ear strap wires, so that the ear strap wires of the mask are often broken due to insufficient length. The duckbill-shaped mask is composed of multiple layers of materials welded and pressed together, but the internal breathing space of this mask is relatively small, and it is easy to cause hypoxia when worn for a long time. In addition, the multiple layers of materials are welded and pressed together, and the pressed boundaries are easy to crack, causing damage to the mask. Summary of the invention

[0044] Example 1

[0045] A mask machine includes an ear band wire conveying device 1000 and a folding, pleating and pressing device 2000. The ear band wire conveying device 1000 and the folding, pleating and pressing device 2000 are arranged vertically up and down. The folding, pleating and pressing device 2000 is arranged above the ear band wire conveying device 1000. The ear band wire passed through the ear band wire conveying device 1000 is arranged in the middle of the mask layer material in the middle of the folding, pleating and pressing device 2000. The ear band wire conveying device 1000 performs telescopic movement between the mask layer materials.

[0046] The ear band line conveying device 1000 includes a fixing component 1100, a driving component 1200 and a conveying component 1300. The driving component 1200 is positioned by the fixing component 1100. The driving component 1200 and the conveying component 1300 are connected. The driving component 1200 can drive the conveying component 1300 to perform telescopic movement. The two layers of material belts of the mask are clamped in the conveying roller of the mask machine. The ear band line is passed through the conveying component 1300 and is located between the two layers of material belts. The conveying component 1300 is located above the conveying roller. The direction of the telescopic movement of the conveying component 1300 is parallel to the axial direction of the conveying roller and perpendicular to the conveying direction of the conveying roller.

[0047] The fixing assembly 1100 includes a first fixing plate 1101 , a first fixing member 1102 and a second fixing member 1103 . The first fixing member 1102 and the second fixing member 1103 are fixed on the first fixing plate 1101 .

[0048] The driving assembly 1200 includes a servo motor 1201, a screw rod 1202 and a screw rod nut 1203. The servo motor 1201 is fixedly connected to the first fixing member 1102. One end of the screw rod 1202 is connected to the output shaft of the servo motor 1201. The screw rod nut 1203 cooperates with the screw rod 1202. Both ends of the screw rod 1202 are positioned in the first fixing member 1102 and the second fixing member 1103. Bearings are arranged between the screw rod 1202 and the first fixing member 1102 and the second fixing member 1103.

[0049] The conveying assembly 1300 includes a conveying rod 1301 and a wire ring 1302 . The conveying rod 1301 is fixedly connected to the screw nut 1203 . The end of the conveying rod 1301 is connected to the wire ring 1302 with a hole, and the ear strap wire is inserted into the wire ring 1302 .

[0050] The wire loop 1302 is made of a low-friction material such as POM plastic, so that the ear strap wire can be smoothly pulled after passing through the wire loop 1302.

[0051] The driving component 1200 and the conveying component 1300 are two groups, and the two ear strap wires are respectively inserted into the two wire loops 1302. The servo motor 1201 drives the screw rod 1202 to rotate, thereby driving the screw nut 1203, the conveying rod 1301, and the wire loop 1302 to perform linear telescopic movement. After passing through the wire loop 1302, the ear strap wire is pressed in the conveying roller by the two layers of fabric of the mask body. As the conveying roller is pressed in the material belt and conveyed forward, during the conveying process of the mask material belt, the conveying rod 1301 is controlled to perform a linear telescopic movement perpendicular to the conveying direction, which can control the position of the wire loop 1302 along the axis direction of the conveying roller, and then control the position of the ear strap wire pressed between the two layers of material belt.

[0052] The two groups of conveying components 1300 can move synchronously or asynchronously. For example, the conveying rod 1301 where one ear band line is located is controlled not to move, so the length of the ear band line is equal to the width of the mask body, and the trajectory of the ear band line is a straight line. The conveying rod 1301 where the other ear band line is located is constantly performing linear telescopic motion. After the ear band line is clamped by the material belt, it will present a wavy shape or a broken line shape. When the ear band line is clamped in the material belt in such a shape, the mask formed after the welding and cutting process can have an ear band line length greater than the width of the mask body.

[0053] By controlling the frequency and amplitude of the linear motion of the delivery rod 1301 as well as the start and end times, the actual length of each ear strap line in each mask can be controlled.

[0054] The ear strap wire delivery device also includes a support rod assembly 1400 and an ear strap wire threading assembly 1500 .

[0055] The support rod assembly 1400 includes a pair of parallel support rods, the axes of which are parallel to the axes of the conveying rollers, and are arranged above the conveying rollers of the mask machine. The support rod 1400 is arranged between the two layers of fabric of the mask body to open up an accommodation space for the conveying rod 1301 and the wire ring 1302 of the conveying assembly 1300, so that the ear strap line can naturally droop in the accommodation space, and the lower end of the ear strap line is accommodated in the middle of the conveying roller and is conveyed downward together with the mask fabric as the conveying roller rotates.

[0056] There are two ear strap wire threading assemblies 1500, and two ear strap wires are respectively threaded therein. The ear strap wires are flat in shape. When the ear strap wires pass through the threading assemblies 1500, the direction of the ear strap wires can be maintained to prevent the ear strap wires from twisting. The ear strap wire threading assemblies 1500 are fixedly connected to the frame of the mask machine.

[0057] The folding, pleating and pressing device 2000 includes a folding component 2100, a pleating component 2200, a conveying component 2300, a first conveying component 2400, a second conveying component 2500 and a second fixed plate 2600.

Both ends of the supporting shaft 2122 are connected to the supporting seat 2121 . The folding plate 2110 is passed through the supporting shaft 2122 and can rotate around the supporting shaft 2122 .

[0060] The adjusting component 2130 includes a first connecting seat 2131, an adjusting stud 2132 and a second connecting seat 2133. The first connecting seat 2131 is fixedly connected to the second fixing plate 2600. Both ends of the adjusting stud 2132 are respectively connected to the first connecting seat 2131 and the second connecting seat 2133. The connection between the adjusting stud 2132 and the first connecting seat 2131 and the second connecting seat 2133 can rotate. The second connecting seat 2133 is fixedly connected to the bottom surface of the folding plate 2110. The folding plate 2110 is arranged downwardly tilted between the supporting component 2120 and the adjusting component 2130. The length of the adjusting stud 2132 can drive the second connecting seat 2133 to move, thereby changing the downward tilt angle of the folding plate 2110.

[0061] The pleating assembly 2200 includes a first shaping wheel axle 2210, a first support frame 2220, a second shaping wheel axle 2230 and a second support frame 2240. Both ends of the first shaping wheel axle 2210 are arranged on the first support frame 2220, and both ends of the second shaping wheel axle 2230 are arranged on the second support frame 2240. The first support frame 2220 and the second support frame 2240 are fixed on the second fixed plate 2600, and the shapes of the first shaping wheel axle 2210 and the second shaping wheel axle 2230 are engaged with each other.

[0062] The short side of the trapezoid of the folding plate 2110 corresponds to the meshing part of the first shaping wheel axle 2210 and the second shaping wheel axle 2230. The length of the shaping meshing part of the first shaping wheel axle 2210 and the second shaping wheel axle 2230 is equal to the length of the short side of the trapezoid of the folding plate 2110. The cloth folded by the folding plate 2110 is pulled between the two shaping wheel axles of the pleating assembly 2200 by the conveying assembly, and wrinkles are generated after rolling over the first shaping wheel axle 2210 and the second shaping wheel axle 2230, and wrinkles are formed in the middle part of the folded mask layer material.

[0063] The conveying assembly 2300 includes a first conveying wheel 2310, a second conveying wheel 2320 and a first conveying wheel mounting frame 2330.

[0064] The mask fabric passes through the first conveying wheel 2310 and the second conveying wheel 2320 on the conveying assembly 2300 in sequence, so that the mask fabric is transferred to the trapezoidal long side of the folding plate 2110. The mask fabric is transferred downward from the bottom edge of the folding plate 2110 along the folding plate 2110 until it is transferred to the trapezoidal short side and the trapezoidal waist side of the folding plate 2110, thereby realizing the folding of the mask layer material.

[0067] The first conveying component 2400 drives the mask fabric to be transmitted forward, and the mask fabric is transmitted to the conveying component 2300, and then transmitted to the folding component 2100 after passing through the conveying component 2300. The mask fabric is transmitted downward along the folding plate 2110 of the folding component 2100, thereby realizing the folding of the mask fabric. The mask fabric folded by the folding component 2100 passes between the two shaping wheel shafts of the pleating component 2200, and wrinkles are generated after rolling over the first shaping wheel shaft 2210 and the second shaping wheel shaft 2230. Wrinkles are formed in the middle part of the folded mask layer material. The support rod 1400 is arranged between the two layers of fabric of the mask body to open up a accommodating space for the conveying rod 1301 and the wire ring 1302 of the conveying component 1300, so that the ear strap line can naturally droop due to gravity in the accommodating space of the two layers of fabric, and the ear strap line and the lower ends of the two layers of fabric are accommodated in the middle of the second conveying component 2500.
