Description

Technical Field

[0001] The utility model belongs to the technical field of mask processing equipment structure, and specifically relates to a multi-layer mask folding mechanism and a mask production line. Background Art

[0002] A mask is a personal protective barrier product, which is worn on the mouth and nose to filter the air entering and exiting the nose and mouth, so as to prevent harmful gases, dust and droplets from entering and exiting the wearer's mouth and nose. The mask has a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent or when working in an environment polluted by dust and other air pollutants, wearing a mask has a good respiratory protection effect.

[0003] Among them, the existing mask folding mechanism has a single structure. If one of the folding parts is damaged, the folding action cannot be continued, and the work cannot be carried out while waiting for the replacement parts to be delivered, which reduces the efficiency. Therefore, it is urgent to propose a new technical solution to solve the above problems. Utility Model Content

[0004] One of the purposes of the utility model is to address the deficiencies of the prior art and provide a multi-layer mask folding mechanism, which provides a first connecting plate and a second connecting plate that are perpendicular to each other, so that when the first folding plate and the second folding plate are working, only one of them can be moved, and the other acts as a fixed component. When one of the components cannot be moved, it can also work, thereby improving work efficiency.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A multi-layer mask folding mechanism is provided with a conveyor belt for transporting mask raw materials, comprising:

[0007] A folding assembly is arranged corresponding to the conveyor belt, the folding assembly includes a top plate and side plates respectively located on opposite sides of the top plate, the side plates are drivingly connected with a first connecting plate and a second connecting plate, the first connecting plate and the top plate are arranged in parallel, the second connecting plate and the first connecting plate are arranged vertically, the first connecting plate is downwardly extended with a first folding plate, the second connecting plate is parallelly extended with a second folding plate, and the first folding plate and the second folding plate are arranged alternately in sequence;

[0008] A pressure roller, arranged corresponding to the conveyor belt, the pressure roller being located on the outer side of the side plate relative to the top plate in the transverse direction;

[0009] A lifting assembly is connected to the top plate and is used for the up and down movement of the folding assembly.

[0010] In actual application, the conveyor belt transports the mask raw material to a set position. After the lifting assembly is lowered to a set height, the first folding plate and the second folding plate contact the mask raw material, and the first folding plate moves toward the second folding plate, and / or the second folding plate moves toward the first folding plate to complete the folding of the mask raw material. After the folded mask raw material is shaped by the pressing roller, the folding assembly is reset. When performing a folding action, only the first folding plate or the second folding plate can perform the action. Therefore, when one of the first folding plate and the second folding plate fails and cannot be moved and needs to be replaced, the other can also complete the folding action while waiting for the replacement of parts, thereby improving work efficiency.

[0011] As an improvement of the multi-layer mask folding mechanism described in the utility model, the first connecting plate and the second connecting plate are respectively connected to the two side plates through a transmission assembly, and the transmission assembly is provided with multiple transmission assemblies, and the transmission assembly includes a mother-and-child rod and a first power cylinder. The first power cylinder is installed on both sides of the first connecting plate or the second connecting plate through a connecting block, and the mother-and-child rods are respectively connected to the output end of the first power cylinder and the side plates. The coordinated use of the mother-and-child rods and the first power cylinder can enable the first connecting plate and the second connecting plate to move in the horizontal axis direction, thereby driving the movement of the first folding plate and the second folding plate to complete the folding of the mask raw material.

[0012] As an improvement of the multi-layer mask folding mechanism described in the utility model, the first folding plate and the second folding plate are horizontally distributed in the horizontal axis direction, and the distance between each first folding plate and the second folding plate adjacent thereto is equal, thereby ensuring the consistency of the folding action.

[0013] As an improvement of the multi-layer mask folding mechanism described in the utility model, the end of the second folding plate close to the conveyor belt is the operating end, and the distance between the operating end and the bottom end of the second connecting plate in the vertical axis direction is L, L≥1cm, which prevents the second connecting plate from contacting the mask raw material, thereby further ensuring the folding effect.

[0014] As an improvement of the multi-layer mask folding mechanism described in the utility model, the lifting assembly includes a mounting plate and a second power cylinder installed on the mounting plate, and the output end of the second power cylinder is located below the mounting plate and connected to the top plate.

[0015] As an improvement of the multi-layer mask folding mechanism described in the utility model, the folding mechanism also includes a bottom plate, the mounting plate includes a first mounting body and a second mounting body connected to each other, the first mounting body and the second mounting body form an L-shaped structure, the first mounting body is arranged parallel to the top plate, and the second mounting body is fixedly mounted to the bottom plate.

[0016] As an improvement of the multi-layer mask folding mechanism described in the utility model, the conveyor belt is arranged on the bottom plate, and the pressure rollers are located at both ends of the conveyor belt.

[0017] As an improvement of the multi-layer mask folding mechanism described in the utility model, the bottom plate is provided with a limit strip, and two limit strips are provided. The two limit strips are respectively located on both sides of the conveyor belt in the longitudinal direction.

The arrangement of the heating resistance wires can perform hot pressing and folding on the mask raw materials, and because the temperature of the hot pressing can only squeeze and stick the mask raw materials together, when in use, they can be torn apart by hand.

[0019] The second purpose of the utility model is to provide a mask production line, including the multi-layer mask folding mechanism as described above.

[0020] The beneficial effect of the utility model is that the multi-layer mask folding mechanism of the utility model is provided with a conveyor belt for transporting mask raw materials, a folding assembly corresponding to the conveyor belt, a pressure roller corresponding to the conveyor belt, and a lifting assembly, the folding assembly includes a top plate and two side plates, the side plates are connected to the first connecting plate and the second connecting plate in a transmission manner, the first connecting plate and the top plate are arranged in parallel, the second connecting plate and the first connecting plate are arranged vertically, the first connecting plate is extended downwardly to be provided with a first folding plate, the second connecting plate is extended in parallel to be provided with a second folding plate, the first folding plate and the second folding plate are arranged crosswise in sequence; the pressure roller is located on the outer side of the side plate relative to the top plate; the lifting assembly is connected to the top plate for the up and down movement of the folding assembly.
