Description

A fully automated production equipment for vertical folding masks

technical field

The utility model relates to a mask production equipment, in particular to a fully automatic production equipment of a vertical folding mask.

Background technique

At present, the production of vertical folding masks (such as KN95 masks) mainly includes semi-automation and full-automation. The semi-automatic vertical folding mask production equipment includes major equipment such as filming module, ear wire welding module, edge sealing module, etc. The machine is used to combine multiple layers of fabrics together by ultrasonic, and insert the nose bridge wire, then knurl and trim to obtain a sheet-like intermediate product; then manually transfer to the ear wire welding module for ear wire welding , and finally carry out edge sealing. The semi-automatic vertical folding mask production equipment has shortcomings such as low efficiency, high labor cost, and large equipment space.

The fully automatic vertical folding mask production equipment overcomes the above shortcomings of semi-automatic equipment, and realizes the fully automatic production of vertical folding masks from feeding to finished products. The fully automatic vertical folding mask production equipment mainly includes a feeding module, a nose bridge wire insertion module, a knurling module, an ear wire welding module, a half-folding module, an edge sealing module, a trimming module and a waste collection module, which are arranged in sequence. The material module is used to transport multiple rolls of fabric to subsequent production stations; the nose bridge wire insertion module is used to fix the nose bridge wire on the fabric; the knurling module is used for ultrasonic rolling on the edge and inside of the vertical folding mask , to realize the composite connection of multi-layer fabrics at the rolling position; the ear wire welding module is used to weld the ear wire to the composite mask base; the half-folding module is used to fold the mask base in half along the center of the mask; the edge sealing module is used to The two sides of the folded mask base are sealed to form a cup-shaped space; the edge trimming module is used to cut the mask from the mask base to obtain a finished vertical folded mask; the waste collection module is used to Collect the waste after cutting the finished vertical folding mask. The existing fully automatic vertical folding mask production equipment greatly reduces labor input and improves production efficiency, but still has the following shortcomings:

In the existing fully automated vertical folding mask production equipment, the knurling process The position is located at the starting position of the production line, and the trimming station is located at the end of the production line. Since the two stations are far apart, and the mask matrix composed of cloth has tensile deformation characteristics, the trimming station is located at the end of the production line. It is very difficult to achieve uniform cutting along the outside of the edge line formed during knurling. It usually takes a long time to debug, making it difficult to put the equipment into use quickly, and errors may occur during use or after changing the fabric, It needs to be re-commissioned, which seriously affects the production efficiency.

2. In the existing fully automatic vertical folding mask production equipment, the mask base is folded in half and then trimmed, and the accuracy of the half-folding also affects the accuracy of trimming, thereby further increasing the difficulty of precise trimming; moreover, the mask substrate is folded in half. When the thickness of the product is doubled, it may slip or not completely cut off during cutting, which affects product quality and production speed.

3. In the existing production process of fully automated vertical folding masks, since the mask body and the mask base are separated at the end, the processes of folding, edge sealing and edge trimming of the mask base must be carried out in sequence in a streamlined manner. , The two stations of edge banding and trimming can only be set before and after a single station, and cannot be set in multiple stations according to needs.

4. In the existing fully automatic vertical folding mask equipment, the processes of folding, sealing and trimming the mask base must be carried out in sequence in a streamlined manner, especially the half-folding process of the mask base. It needs a long conveying distance to complete the half-folding, so that the length and size of the entire production equipment are large.

5. In the existing fully automatic vertical folding mask production equipment, the mask base body after folded in half is in an upright state, and the mask base body in the upright state is edge-sealed and trimmed during the conveying process, which is difficult to locate, and also leads to edge-sealing and cutting. Edge accuracy is difficult to guarantee.

6. Along the conveying direction of the mask base body, the positioning of the mask base body at each processing station is realized by controlling the conveying stroke of the mask base body. Due to the stretching deformation and slippage of the mask base body during the conveying process, the masks The positioning accuracy of the base body at each machining station.
