Specifically, the upper end of the second intermediate screw 631 passes through the fourth driven wheel 623 and is in threaded connection with the fourth driven wheel 623, and the second rotary driving element 621 is configured to drive the second intermediate screw 631 to rotate downward through the fourth transmission gear set; further, the two second intermediate screws 631 are connected by a belt transmission member 624, so as to realize synchronous downward rotation of the two second intermediate screws 631, specifically, the second intermediate screws 631 are detachably connected with a rotating roller, and a transmission belt is connected between the two rotating rollers.
It should be understood that, when the second intermediate screw 631 rotates downward, the second intermediate screw 631 drives the rotating roller and the four-stage driving wheel 622 to move downward simultaneously, and the consistency of the pressing degree of the two longitudinal ends of the upper die holder 4 can be determined according to the deviation degree of the two ends of the conveyor belt.
The foregoing description of the preferred embodiments of the application is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the application.
