Description

Technical Field

[0001] The utility model relates to the technical field of mask packaging equipment, and in particular to a flattening device for 3D mask packaging. Background Art

[0002] People are more familiar with ordinary masks, which are flat masks. Ordinary masks on the market are also individually packaged, and there are many varieties, including cotton and sponge. When people wear this kind of mask, there will still be gaps around the face and nasal cavity, and the sealing is relatively not very good. The three-dimensional mask is different. It has been improved in design to reduce the entire coverage area, but it fits the shape of the face very well, so it can effectively fit the nose, face, chin and other parts to form a dense and ventilated space, thereby better protecting people, but it is relatively easy to feel stuffy after wearing this three-dimensional mask.

[0003] In the production and packaging process of 3D masks, they are generally folded from the middle, and then connected and shaped by hot pressing equipment along the stitching line, and then directly bagged and packaged. Although the packaging environment is a sterile environment, which can ensure product quality, the packaging bag is not sealed, so it is easy to cause subsequent contamination and loss during subsequent transportation and storage. Although the existing vacuum packaging can solve this problem, the 3D mask itself has a certain amount of hollowness. When vacuuming, the packaging bag will appear wrinkled or even shrink into a ball due to the uneven shrinkage of the internal space of the packaging bag, and there is room for further improvement. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a flattening device for 3D mask packaging, which solves the above problem by flattening the mask and then vacuum packaging it.

[0005] To achieve the above-mentioned purpose, a flattening device for 3D mask packaging is provided, comprising a bottom plate, a mounting frame is fixedly connected to the top of the bottom plate, a fixed splint is fixedly connected to one side of the mounting frame, a flattening splint is slidably connected to a symmetrical position corresponding to the fixed splint on a side of the mounting frame away from the fixed splint, a vacuum sealing ring is fixedly connected to the middle part of the upper inner side of the fixed splint and the flattening splint, an air extraction hole is opened on the fixed splint at a position corresponding to the center of the vacuum sealing ring, a vacuum extraction tube is fixedly connected to a position corresponding to the air extraction hole on a side of the fixed splint away from the vacuum sealing ring, and an electric heating strip is fixedly connected to the inner side of the fixed splint and the flattening splint below the vacuum sealing ring;

[0006] The inner sides of the fixed splint and the flattening splint are slidably embedded with a mask pressing plate in the middle part below the electric heating strip, the inner sides of the two mask pressing plates are fixedly connected with elastic pads, the upper and lower ends of the mounting frame on the side away from the fixed splint are fixedly connected with cylinder fixing plates, and the middle part of the side of the two cylinder fixing plates away from the flattening splint is fixedly connected with a driving cylinder.

[0007] According to the flattening device for 3D mask packaging, a mask conveyor is arranged above the bottom plate in the middle of the mounting frame.

[0008] According to the flattening device for 3D mask packaging, the middle parts of both sides of the mounting frame away from the fixed clamp plate are fixedly connected to the limiting slide seats, and the two ends of the flattening clamp plate are fixedly connected to the sliding plates at the positions corresponding to the limiting slide seats.

[0009] According to the flattening device for 3D mask packaging, both ends of the flattening clamp are slidably connected to the corresponding limiting sliding seats through sliding plates.

[0010] According to the flattening device for 3D mask packaging, nickel-chromium heating strips are arranged on the inner sides of the two electric heating strips.

[0011] According to the flattening device for 3D mask packaging, the output ends of the two driving cylinders on the side close to the flattening splint are fixedly connected to the flattening splint through the corresponding cylinder fixing plates.

[0012] According to the flattening device for 3D mask packaging, a vacuum sensor is provided above one end of the vacuum tube close to the fixed splint.

[0013] According to the flattening device for 3D mask packaging, a controller is provided at the corner of the upper end of the bottom plate.

[0014] The above solution has at least one of the following beneficial effects:

[0015] 1.

In combination with an electric heating strip, the mask can be directly vacuumed and heat-sealed to prevent subsequent contamination and loss, thereby enhancing the practicability of the device.

[0016] 2. The fixed splint and the flattening splint of the utility model are provided with a mask pressing plate, which cooperates with the elastic pad. Before vacuum packaging, the mask body and its external packaging can be flattened by closing the fixed splint and the flattening splint to prevent the mask itself from being hollow and causing wrinkles in the packaging bag or even shrinking into a ball. The elastic pad can prevent the mask pressing plate from being too tight to form a support that affects the sealing of the vacuum sealing ring and press the metal strip of the mask to excessive deformation, thereby enhancing the practicality of the device.
