Description

Technical Field

[0001] The invention relates to the field of mask processing, and in particular to a full-automatic production line for cup-shaped masks. Background Art

[0002] The N95 cup-type masks we come into contact with in daily life are composed of three layers of needle-punched cotton, meltblown cloth and non-woven fabric. The outer layer of the N95 cup-type mask is used to prevent droplets, the middle layer is used for filtration, and the inner layer is used for moisture absorption. The meltblown cloth of the N95 cup-type mask is usually 40 grams or even heavier, plus the thickness of the needle-punched cotton, so its appearance is thicker than that of ordinary flat masks, and its protection effect can reach at least 95%.

[0003] When producing this type of N95 cup-type mask, it is necessary to compound three layers of fabric: needle-punched cotton, meltblown fabric and non-woven fabric, and then go through a series of processes such as edge sealing, cutting, printing, nose bridge welding, ear strap welding and packaging, and the N95 cup-type mask is completed.

[0004] In the prior art, when compounding the three layers of fabrics, namely, needle-punched cotton, melt-blown fabric and non-woven fabric, the needle-punched cotton, melt-blown fabric and non-woven fabric are usually extruded and formed separately, and then overlapped manually in order to prepare for the next process. Manually overlapping fabrics leads to low production efficiency and cannot guarantee the accuracy of the overlapping position; manual participation can also easily lead to pulling and damage of the fabric due to poor control of the force; mask production needs to be carried out in a sterile environment, and manual participation may also cause contamination of the fabric; and the difficulty of automatic connection control in the entire production line process is mainly in the compounding of the three layers of fabrics, the cutting of the mask after compounding, and the automatic material transfer between different workstations.

[0060] See attached Figure 1-3 The shell conveying device 201 extends to the edge sealing unit 5, the shell conveying unit 201 and the feeding unit 7 are staggered, and the two have overlapping parts in a direction perpendicular to the shell conveying device 201. The shell conveying device 201 can transfer the composite mask to the position of the feeding unit 7, so that the mask is transferred from the shell conveying device 201 to the feeding unit 7.

[0061] When in use, the fabric of the outer shell is formed through the outer shell production line 2, the fabric of the inner shell is formed through the inner shell production line 3, and the meltblown fabric is formed through the meltblown fabric production line 1. The three layers of fabric after forming are automatically compounded again through the compounding unit 4, and after compounding, they are passed through the edge sealing unit 5 and the starting unit 6 to realize the edge sealing and cutting of the mask. The whole device can realize the automatic feeding, conveying, segmentation, shaping of the fabric required for mask production and the compounding of multiple layers of fabric. The clever use of automated devices replaces the large amount of manual participation in the prior art, avoids contact between personnel and fabrics during the mask production process, ensures the quality of mask production, and especially realizes automatic compounding, automatic conveying, and automatic cutting between multiple layers of fabric, solves the current problems in the automated production process of masks, and effectively improves production efficiency.

[0062] In a preferred embodiment, the outer shell conveying device 201 and the inner shell conveying device 301 are configured to have the same structure, respectively including a clamping mechanism 8 and a conveying mechanism 9. The conveying mechanism 9 is arranged along the outer shell production line 2 or the inner shell production line 3. The clamping mechanism 8 can clamp the side of the outer shell or the inner shell to follow the movement of the conveying mechanism 9.

[0063] In a preferred embodiment, the conveying mechanism 9 includes two first guide rails 901, two first sliding seats 902 and a first synchronous belt mechanism 903. The two first guide rails 901 are symmetrically arranged along the two sides of the outer shell forming die or the inner shell forming die, and the two first sliding seats 902 are respectively slidably matched with the two first guide rails 901, and the first synchronous belt mechanism 903 is connected to the two first sliding seats 902; the clamping mechanism 8 includes a plurality of first pneumatic clamps 801, and the plurality of first pneumatic clamps 801 are respectively connected to the two first sliding seats 902, and the first pneumatic clamps 801 of the two first sliding seats 902 are arranged one by one;

[0064] The first sliding seat 902 includes a base 9021 and a lifting frame 9022. The base 9021 and the first guide rail 901 are slidably matched. The lifting frame 9022 is connected to a plurality of first pneumatic clamps 801, so that the clamping mechanism 8 can move along the vertical direction following the lifting frame 9022. Because the fabric of the mask needs to be moved when passing through the outer shell production line 2 or the inner shell production line 3 and the subsequent compounding process, and because of the particularity of the cup-shaped mask, when the fabric formed in the die is moved backward and transported, it is necessary to use the lifting frame 9022 of the first sliding seat 902 to lift the fabric out of the die, and then move and transport it along the first guide rail 901. After moving to the die corresponding to the next station, the lifting frame 9022 descends again, and the fabric clamped by the clamping mechanism 8 falls into the die accordingly, so as to realize the automatic feeding and transfer of the cup-shaped mask.

[0065] In a preferred embodiment, the driving device 103 includes two second guide rails 1031, two second sliding seats 1032 and a second synchronous belt mechanism 1033. The two second guide rails 1031 are symmetrically arranged along the two sides of the meltblown cloth die 1021, and the two second sliding seats 1032 are respectively slidably matched with the two second guide rails 1031, and the second synchronous belt mechanism 1033 is connected to the two second sliding seats 1032; the two second sliding seats 1032 are also connected to the meltblown cloth die 1021, so that the meltblown cloth die 1021 moves following the second sliding seats 1032. In this embodiment, the meltblown cloth production line 1 is different from the outer shell production line 2 and the inner shell production line 3 in that the meltblown cloth cavity 1021 is connected to the driving device 103 and can move along the second guide rail 1031 following the second sliding seat 1032. This is because the material of the meltblown cloth is different from the material of the outer shell and the inner shell. In the process of the meltblown cloth being stretched and formed by the stretching device 1022, the driving device 103 needs to move to make the meltblown cloth displace synchronously and cooperate with the action of the stretching device 1022 to avoid deformation and tearing of the meltblown cloth when the corresponding part of a single mask is stretched by the stretching device 1022. Therefore, the driving device 103 drives the meltblown cloth cavity 1021 to move between the stretching device 1022 and the meltblown cloth composite station, thereby realizing automatic forming and composite of the meltblown cloth.

[0066] In a preferred embodiment, the opening device 1022 includes a lifting mechanism 10221 and a punch 10222, wherein the punch 10222 is provided with a hole located above the meltblown cloth concave mold 1021, and the lifting mechanism 10221 is connected to the punch 10222, and is used to drive the punch 10222 to move in the vertical direction to cooperate with the meltblown cloth concave mold 1021 to open the meltblown cloth. The punch 10222 can move up and down driven by the lifting mechanism 10221, and when the meltblown cloth groove 1021 drives the meltblown cloth to move to the position below the punch 10222, the punch 10222 moves downward, and cooperates with the meltblown cloth concave mold 1021 to open the meltblown cloth to achieve molding.

[0067] The meltblown cloth forming device 102 also includes a feeding rack 1023, a sewing mechanism 1024 and an unfolding mechanism 1025. The feeding rack 1023 is arranged at the front end of the meltblown cloth production line 1, and is used to set a meltblown cloth roller and provide meltblown cloth. The sewing mechanism 1024 is provided with a plurality of guide roller groups 10241 and a vibrator 10242, a vibration table 10243 and a sewing roller 10244.
