Further, in order to more conveniently adjust the horizontal positions of the two movable dies 130, in one embodiment of the present invention, the pressing device 100 further includes a movable die slide driving mechanism including a movable die slide screw 141, a connecting plate 142, and a movable die slide driving motor 143. Wherein, two ends of the movable pressing die sliding screw rod 141 are rotatably arranged on the base 110; the connecting plate 142 is slidably mounted on the movable die sliding screw rod 141, and the connecting plate 142 is fixedly connected with the third slider 112 on the transverse guide rail 111; the output end of the movable die sliding driving motor 143 is connected to the movable die sliding lead screw 141 for driving the movable die sliding lead screw 141 to rotate, and driving the connecting plate 142 to make linear motion along the movable die sliding lead screw 141, so as to drive the third slider 112 and the integral movable die 130 to move horizontally.

By using the above-described movable die slide driving mechanism, the movable die 130 can be easily driven to move on the base 110 in the horizontal direction, and the horizontal position of the movable die 130 and the interval between the two movable dies 130 can be easily adjusted.

It should be noted that the connecting plate 142 is slidably mounted on the movable die sliding lead screw 141, specifically, a nut is disposed on the connecting plate 142, the nut is sleeved on the movable die sliding lead screw 141 and is in threaded fit connection with the movable die sliding lead screw 141, and the nut and the movable die sliding lead screw 141 together form a lead screw-nut pair. The two ends of the movable die sliding screw rod 141 are rotatably mounted on the base 110, specifically, two rotating supports are mounted on the base 110, and the two ends of the movable die sliding screw rod 141 are rotatably mounted on the rotating supports.

Further, in one particular example, the movable die slide screw 141 includes a first screw segment 1411 and a second screw segment 1412 that are connected to each other. The spiral directions of the threads on the first screw rod section 1411 and the second screw rod section 1412 are opposite, so that a bidirectional screw rod is formed; the movable dies 130 on both sides of the fixed die 120 are connected to the first lead screw section 1411 and the second lead screw section 1412 through a connecting plate 142. Specifically, the movable die 130 located on the left side of the fixed die 120 is connected to the first lead screw section 1411 by a connecting plate 142, and the movable die 130 located on the right side of the fixed die 120 is connected to the second lead screw section 1412 by a connecting plate 142.

The first screw rod section 1411 and the second screw rod section 1412 are adopted to form a bidirectional screw rod, and the two movable pressing dies 130 are respectively arranged on the first screw rod section 1411 and the second screw rod section 1412; the first lead screw section 1411 and the second lead screw section 1412 are driven to rotate together by the movable pressing die sliding driving motor 143, so that the two movable pressing dies 130 can be driven to move in opposite directions, and the distance between the two movable pressing dies 130 can be conveniently adjusted, so that the pressing device 100 can adapt to shirt collars of different styles.

Specifically, when the distance between the two movable dies 130 needs to be increased, the first lead screw segment 1411 and the second lead screw segment 1412 are driven to rotate only by the movable die slippage driving motor 143, so that the two movable dies 130 move in opposite directions; when the distance between the two movable dies 130 needs to be reduced, the movable die slippage driving motor 143 is only needed to drive the first lead screw section 1411 and the second lead screw section 1412 to reversely rotate, so that the two movable dies 130 move towards each other.

It can be understood that the movable die slide driving motor 143 in the movable die slide driving mechanism can be connected with the movable die slide screw rod 141 for transmission through the existing transmission modes such as a chain wheel transmission mechanism, a belt wheel transmission mechanism and the like. The connection position of the transmission mechanism and the movable die sliding screw rod 141 is preferably arranged at the middle position of the movable die sliding screw rod 141, namely the connection position of the first screw rod section 1411 and the second screw rod section 1412.
