After the motor is started, the belt 11 installed on the No. 1 pulley 28 or the No. 2 pulley 29 will continue to rotate toward the motor. At this time, under the action of the linkage structure, the belt 11 installed on the No. 2 pulley 29 or the No. 1 pulley 28 will continue to rotate away from the motor, thereby driving the two groups of reciprocating parts to move closer to or away from each other.

[0039] See also Figure 3 , Figure 4 It should be noted that, in the initial state, the two sets of sleeves 13 are close to each other and located in the middle of the mask piece, and the above-mentioned spring 16 is in a compressed state. The spring 16 in the compressed state pushes the telescopic rod 12 away from the sleeve 13. At this time, the ball 9 under the telescopic rod 12 is in contact with the support plate 8, and the mask piece that has been integrated after passing through the two sets of vertical plates 3 can be clamped. When the mask piece is conveyed to the forming and welding mechanism 4, the ball 9 installed on the telescopic rod 12 will roll, so that the telescopic rod 12 will not cause damage to the surface of the mask piece during operation.

[0040] The interlocking groove body includes a transverse groove 21, a vertical groove 22 and an inclined groove 24, wherein the transverse groove 21, the vertical groove 22 and the inclined groove 24 form a closed structure, and a barrier structure is provided at the connection between the inclined groove 24 and the transverse groove 21;

In the initial state, the two groups of telescopic rods 12 arranged laterally are close to each other, and the balls 9 at the ends of the telescopic rods 12 are in contact with the support plate 8 to clamp the mask sheet in the middle. When the movable plate 10 is driven by the belt 11 to move away from the gear set 7 along the clamping groove 15, the fixed rod 14 will move toward the inclined groove 24 along the transverse groove 21 until the fixed rod 14 contacts the rotating plate 25 and pushes the rotating plate 25 to deflect toward the storage groove 30, so that the spring piece 26 is squeezed, and the rotating plate 25 passes through the arc groove 27 and gradually sinks into the storage groove 30. Then the balls 9 are separated from the mask sheet, and after the fixed rod 14 is separated from the rotating plate 25, the spring piece 26 releases its elastic potential energy. , pushing the rotating plate 25 to reverse and maintain a parallel state with the inclined groove 24, the belt 11 continues to drive the movable plate 10 to move along the clamping groove 15, driving the fixed rod 14 to move to the end of the stroke of the transverse groove 21; then the movable plate 10 moves toward the gear set 7 driven by the belt 11, and moves upward along the inclined groove 24 under the guidance of the rotating plate 25. At this time, the sleeve 13 rises along the T-slot 19 to separate the ball 9 from the support plate 8, and then the fixed rod 14 moves along the reset groove 23 until the fixed rod 14 moves to the end of the reset groove 23. Under the action of gravity, the sleeve 13 falls back to the head end of the transverse groove 21 along the vertical groove 22, and the above process is repeated to flatten the mask sheet so that the mask sheet will not be wrinkled and the defective rate is reduced.

When the movable plate 10 reciprocates along the clamping groove 15, the two groups of telescopic rods 12 along the vertical direction of the workbench 1 space approach each other. At this time, the balls 9 arranged at the ends of the telescopic rods 12 are fitted with the support plate 8. Then, under the action of the movable plate 10, they move to both sides along the middle of the mask piece to flatten the wrinkled part of the mask piece. Then, the two groups of balls 9 are separated, and under the cooperation of the engaging groove body and the movable plate 10, the telescopic rods 12 approach each other and return to the initial position. Then, the balls 9 are fitted with the support plate 8 again, and the above process is repeated. The mask piece passing between the two groups of vertical plates 3 can be continuously leveled to prevent wrinkles in the mask piece and reduce the defective rate.
