Description

Technical Field

[0001] The invention relates to a full-servo high-speed production line for elastic ear-band flat masks. Background Art

[0002] With the rapid spread of the coronavirus in the world, the demand for masks is increasing, resulting in a large number of types and styles of masks, and uneven quality. The ear straps of existing disposable flat masks are generally made of elastic ropes such as spandex and polyester. The contact area between the ear straps of this structure and the ears is small. After wearing the mask for a long time, the ears will be tightened, resulting in discomfort. At the same time, in the production of existing disposable flat masks, the fixation of the ear straps is generally completed through secondary processing, resulting in certain limitations in its production efficiency. With the epidemic in a stable state and the requirements and demands for mask standards, the existing disposable masks and production efficiency can no longer meet the needs of the current people and the market, so it is necessary to improve the existing masks, but the improvement of masks also requires matching mask production equipment.

[0049] The main structures of the mask embossing mechanism on both sides, the mask embossing mechanism at both ends, the ear strap pressure point mechanism, and the mask forming and cutting mechanism of the present invention are the same as those of the existing mask manufacturing hot pressing and circumferential cutting mechanisms. The difference lies in the different shapes and positions of the blades of the upper roller body and the lower roller body, which will not be described in detail.

[0050] The bellows transmission assembly of the present invention is substantially the same as the existing bellows transmission assembly, so it will not be described in detail.

[0053] When the present invention is used, each material roll is fixed on the frame through an air expansion shaft, driven by a servo motor, and the material switching operation is performed through an automatic material switching device. When the skin-friendly layer material, the melt-blown cloth layer material, and the outer layer material overlap and move to the transmission roller, and are about to enter the embossing mechanism on both sides of the mask, the nose bridge strip passes through the feed pipe, and the cutting and segmentation are completed by the action of the cutter. Then, the nose bridge strip falls on the upper end of the outer layer, and then the two sides of the mask are folded, the nose bridge strip is wrapped, and then the two sides of the mask are hot-pressed by the embossing mechanism on both sides of the mask to form embossing 35, and then the mask is partially folded by the three-fold folding mechanism of the mask (usually a combination of a folding wheel and a folding plate), and then enters In the embossing mechanism at both ends of the mask, the two ends of the mask are hot-pressed. After the hot-pressing is completed, it moves to the bellows assembly 1. At the same time, the lining material feeding mechanism, the ear band material is folded by the ear band folding plate, and then the folded part is dotted by the ear band folding dotting mechanism to make it connected and fixed. Then, the ear band material is cut by the leveling mechanism and the ear band slitting mechanism. The cut ear band material is placed on the upper end of the outer layer of the mask material (adsorbed by the action of the bellows), and then enters the ear band pressing point mechanism to hot-press the ear band on the outer layer of the mask and the folded skin-friendly layer. Finally, it moves to the mask forming and cutting mechanism to cut and shape the mask, and finally moves to the external conveying equipment through the bellows transmission assembly.

[0054] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto.
