Description

Technical Field

[0001] The invention belongs to the technical field of mask manufacturing equipment, and in particular relates to a folding mechanism of a full-automatic N95 mask machine. Background Art

[0002] N95 mask machine refers to a series of flat and three-dimensional mask machines that use N95 non-woven fabrics as raw materials and can produce N95 masks. For folding N95 mask machines, it can automatically complete multiple processes from feeding to one-time molding, shearing and material return. Compared with traditional manual feeding, material return and shearing, it can save 3-5 manpower and produce 30-36 masks per minute. This mask machine mainly uses a conveyor belt to compound various non-woven fabrics and melt-blown fabrics for molding. After ultrasonic edge sealing, the ear strap welding device is used to weld the ear straps, and then it needs to be folded in half through a triangular folding plate, and then shaped through a certain length of folding molding clamping and feeding mechanism before it can be cut and discharged and returned. At present, when this type of equipment is handing over fabrics in the ear strap welding process, folding process, and slitting process, the inertial shape of the fabric will form resistance when entering different workstations, which can easily affect the smoothness of the equipment operation. Therefore, it is necessary to extend the production line and use the transmission mechanism to gradually shape the fabric to complete the mask's folding, slitting, ear strap moving up, and material discharging and returning processes. The equipment occupies a large area and has low efficiency, which is one of the current problems with N95 folding masks. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a folding mechanism for a fully automatic N95 mask machine, which utilizes the principle of mechanics to reduce the inertia of the cloth running and enable it to be quickly shaped, thereby helping to reduce the size of the equipment and improve production efficiency.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] The present invention discloses a folding mechanism for a fully automatic N95 mask machine, which mainly comprises a conveying mechanism, an ear strap welding device, a folding mechanism and a cutting mechanism. The conveying mechanism is connected to the folding mechanism. The folding mechanism comprises an inner forming body which is inclined downward and is in a tunnel shape, and a shaping body which is located above the inner forming body. Jet devices are arranged on both sides of the lower part of the inner forming body, and ear strap folding plates are arranged on both sides of the inner forming body. A vertically arranged cloth pressing roller is arranged between the folding mechanism and the cutting mechanism.

[0006] The shaping body of the present invention is half-wrapped in the inner forming body, and the shaping body covers the upper two sides of the front half of the inner forming body, the ear strap folding plate covers the lower two sides of the front half of the shaping body, and the ear strap folding plate covers the two sides of the rear half of the inner forming body.

[0007] The shaping body of the present invention is provided with a plurality of rolling wheels along the upper side of the inner forming body.

[0008] The jetting device of the present invention is located at the punching position of the inner forming body to jet airflow toward the outside.

[0009] The rear half of the ear strap folding plate of the present invention is provided with window positions on both sides.

[0010] The outer side of the window opening of the present invention is provided with a gluing mechanism.

[0011] The present invention changes the structure and guidance of the traditional folding mechanism, shapes the cloth downward, uses the inner forming body and the shaping body to fold and shape the cloth, and folds the ear strap upward, which can eliminate the inertia of the cloth running and directly enter the slitting device to slit the cloth, without the need for long-term slow shaping and folding the ear strap upward after slitting and then discharging and returning the cloth. Compared with the traditional folding mechanism, this can greatly reduce the size of the equipment and improve production efficiency.
