The adjusting mechanism 2 includes a movable support member 21 movably arranged in the positioning channel 3, and an adjusting member 22 movably arranged on the centering steel structure 1, so that the adjusting member 22 drives the movable support member 21 to push or retract the screw shaft of the feeder for centering. Through the setting of this structure, through the positioning channel 3 on the centering steel structure 1, the centering steel structure 1 is installed on the screw shaft of the feeder, and a basic positioning of the screw shaft of the feeder is performed. At the same time, through the contact between the movable support member 21 and the screw shaft of the feeder, a buffering effect is provided when the screw shaft of the feeder is offset, thereby avoiding damage to the centering steel structure and the screw shaft of the feeder. After the adjusting member 22 is offset during operation of the feeder screw shaft, the position and angle of the feeder screw shaft can be adjusted by simply adjusting the position of the adjusting member 22, so that the feeder screw shaft reaches a predetermined position, and can be further accurately aligned manually, ultimately achieving the purpose of auxiliary alignment, thereby facilitating rapid and accurate alignment. The embodiment of the utility model can preferably be applied to the field of liquid crystal glass manufacturing, such as feeders in glass industry equipment.

[0025] Furthermore, the movable support 21 corresponds to the screw shaft of the feeder, and a first threaded hole is provided on the centering steel structure 1, and the adjusting member 22 is threadedly connected to the centering steel structure 1 through the first threaded hole, so that the adjusting member 22 can push or retract the movable support 21 after rotating. Through the setting of this structure, the adjusting member 22 is preferably a bolt, and the bolt is rotated on the centering steel structure 1 to change the length of the adjusting member 22 screwed into the centering steel structure 1, so that after the adjusting member 22 contacts the movable support 21, the adjusting member 22 is continued to rotate forward or reversely to facilitate pushing or retracting the screw shaft of the feeder for centering. It has a simple structure, is easy to operate, and can achieve rapid positioning when installing the shaft.

[0026] Furthermore, the inner wall of the movable support 21 is adapted to the outer wall of the screw shaft of the feeder, and an elastic member is provided between the outer wall of the movable support 21 and the inner wall of the positioning channel 3, so that the movable support 21 is pushed or retracted by the adjusting member 22 in the positioning channel 3. Through the arrangement of this structure, the elastic member can preferably be an elastic structure such as a spring or a spring sheet, so that after the movable support 21 is installed in the positioning channel 3, the movable support 21 can still move slightly, so as to provide a buffering effect when the screw shaft of the feeder is offset, and the screw shaft of the feeder is centered by the rotation of the adjusting member 22.

[0030] Or a fixed support is provided on the inner wall of the positioning channel 3, and the inner wall of the fixed support and the movable support 21 are adapted to the outer wall of the screw shaft of the feeder. A limited gap is formed between the inner wall of the positioning channel 3 and the outer wall of the fixed support, and the measuring piece 4 is located in the limited gap between the positioning channel 3 and the fixed support. Through the setting of this structure, the limited gap formed between the movable support 21 or the fixed support and the positioning channel 3 is utilized to support and limit the measuring piece 4 during the installation process of the measuring piece 4, thereby facilitating the stable installation of the measuring piece 4.

An upper rib plate 7 is provided on one of the steel structure bodies 11, and a lower rib plate 8 is provided on the other steel structure body 11. The upper rib plate 7 and the lower rib plate 8 are detachably connected so that the two steel structure bodies 11 are seamlessly fixed after the upper rib plate 7 and the lower rib plate 8 are connected. Through the setting of this structure, the centering steel structure 1 is divided into two detachably connected steel structure bodies 11. The two steel structure bodies 11 can be docked on the screw shaft of the feeder respectively, and then the two steel structure bodies 11 are connected and fixed, so as to facilitate the rapid installation and rapid disassembly of the centering steel structure 1. Preferably, the detachable connection between the upper rib plate 7 and the lower rib plate 8 can be connected by conventional detachable structures such as bolts.

[0033] Furthermore, the steel structure body 11 includes a mounting seat 111 and a positioning plate 112. The positioning plate 111 corresponds to the screw shaft of the feeder, so that the positioning plates 112 of the two steel structure bodies 11 are docked to form a positioning channel 3. Among them, an upper rib plate 7 is arranged on the positioning plate 112 of one of the steel structure bodies 11, and a lower rib plate 8 is arranged on the positioning plate 112 of the other steel structure body 11.
