[0023] See also Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the present application proposes an anti-wrinkle cutting device for a mechanical-sized mask, comprising: a frame 1; a conveyor belt 4, which is rotatably arranged on the frame 1, and the mechanical-sized mask is placed on the conveyor belt 4; a conveying drive, which is used to drive the conveyor belt 4 to make a rotational motion; a cutting head, which is movably installed on the frame 1; a cutting drive, which drives the cutting head to move back and forth; a first tensioning roller 5, which is rotatably arranged on the frame 1 and is located on one side of the cutting head, and the outer peripheral surface of the first tensioning roller 5 partially contacts the mechanical-sized mask; a second tensioning roller 11, which is rotatably arranged on the frame 1 and is located on the other side of the cutting head, and the outer peripheral surface of the second tensioning roller 11 partially contacts the mechanical-sized mask; two tensioning drives, which are installed on the frame 1, one tensioning drive drives the first tensioning roller 5 to rotate forward or reverse, and the other tensioning drive drives the second tensioning roller 11 to rotate forward or reverse.

[0024] Among them, the frame 1 is the structural basis of the anti-wrinkle cutting device for mechanical-sized facial masks, which is responsible for connecting and carrying other components. The conveyor belt 4 and the conveying drive constitute a conveying unit, and the conveying drive drives the conveyor belt 4 to make a rotary motion, which is used to transport the mechanical-sized facial mask on the conveyor belt 4 to the lower side of the cutting head and cut it by the cutting head. The cutting head and the cutting drive constitute a cutting unit, and the cutting drive drives the cutting head to make a reciprocating linear motion to cut the mechanical-sized facial mask continuously for multiple times to obtain a finished mechanical-sized facial mask of the required specifications. The first tensioning roller 5 and the second tensioning roller 11 are the core components of the anti-wrinkle cutting device for mechanical-sized facial masks, which are used to prevent wrinkles from appearing on the mechanical-sized facial mask to be cut.

[0025] Specifically, a long strip of the type-shaped facial mask is placed on the conveyor belt 4, and the conveyor belt 4 is driven to rotate by the conveying drive, thereby driving the type-shaped facial mask on the conveyor belt 4 to move. When the uncut area of ​​the type-shaped facial mask is transported to the lower side of the cutting head, one tensioning drive drives the first tensioning roller 5 to rotate forward, and another tensioning drive drives the second tensioning roller 11 to reverse, so as to tension the type-shaped facial mask therein, thereby removing the wrinkles of the type-shaped facial mask in the uncut area. Afterwards, the cutting head is driven downward by the cutting drive to cut out the finished product of the mechanical mask of a specific specification. After cutting, the conveying drive drives the conveyor belt 4 to make a rotational motion, thereby driving the cut mechanical mask to be moved out, and driving the new uncut area of ​​the mechanical mask to be transported to the lower side of the cutting head. The above operations are repeated to obtain finished mechanical masks in batches, and by setting the first tensioning roller 5 and the second tensioning roller 11, the mechanical mask is difficult to produce wrinkles, that is, the yield rate of the finished mechanical mask is high, which improves production efficiency and reduces production costs.

[0026] In detail, the wrinkle-proof cutting device for the mechanical mask also includes a control center. The control center sends a signal to control the conveying drive to bring the uncut area of ​​the mechanical mask on the conveyor belt 4 to the lower side of the cutting head. At this time, the control center sends a signal again, and the two tensioning drives receive the signal and control the first tensioning roller 5 to rotate forward 1 / 4 circle, and the second tensioning roller 11 to rotate backward 1 / 4 circle at the same time, and the two have the same rotation speed to remove the wrinkles on the mechanical mask. At this time, the control center can detect the mechanical mask again. If wrinkles are found, the above wrinkle removal operation can be repeated. When the wrinkles are removed, the control center sends a signal, and the cutting drive drives the cutting head to cut the mechanical mask. Then, the control center repeatedly controls each component to perform the above operations to obtain a finished mechanical mask with a high yield rate. After the mechanical mask is cut, it will not break along its moving direction, that is, the finished mechanical mask is cut from the middle of the mechanical mask, and the two sides of the mechanical mask will not be cut by the cutting head, so as to ensure that the mechanical mask can be cut continuously and automatically.

By setting the limiting groove 13, the lateral position of the mechanical mask can be effectively limited, which is convenient for subsequent cutting work. The depth of the limiting groove 13 is slightly smaller than the height of the mechanical mask. The outer peripheral surface of the first tensioning roller 5 and the second tensioning roller 11 is against the conveyor belt 4, that is, the first tensioning roller 5 and the second tensioning roller 11 have a certain extrusion force on the mechanical mask, which is conducive to removing the wrinkles on the mechanical mask and will not damage the mechanical mask.

The active roller 6 and the driven roller 20 are both arranged on the inner side of the conveyor belt 4, and the shape-adjusting roller 16 is located on the outer side of the conveyor belt 4.
