Description

Technical Field

[0001] This utility model relates to the field of book page processing technology, specifically a manual / automatic cover adjustment mechanism. Background Technology

[0002] In the perfect binding process of book blocks, inner and outer guides are needed for positioning. However, the current method mainly relies on workers to manually adjust the positions of the left and right guides and the front guide to position the paper. This method requires a lot of work, is time-consuming and labor-intensive, and is prone to human error, affecting the paper separation effect. While existing electric adjustment can meet the function of rapid adjustment, it cannot be used once it malfunctions. The adjustment method is also limited and inconvenient to use. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a cover manual and automatic adjustment mechanism with simple structure and easy operation. It can not only be adjusted by electric means, but also manually adjusted by two rules separately, making it more flexible to use and effectively solving the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cover manual / automatic integrated adjustment mechanism, including frame side plates, a linear guide rail fixedly arranged between the two frame side plates, two supports fixed in the middle of the linear guide rail, and lead screws rotatably connected between the two supports and the two frame side plates respectively. Two slidingly connected gauge supports are provided on the linear guide rail, with an inner gauge and an outer gauge respectively connected to the two gauge supports. The two lead screws are respectively connected to the inner and outer gauges via threaded connections. A servo motor is provided on each of the two frame side plates, and the output shafts of the two servo motors drive the two lead screws to rotate via sprockets and chains respectively. A handwheel is fixed to the end of the output shaft of the front servo motor, and a hand-cranked adjustment component that drives the rear lead screw to rotate is provided between the two frame side plates.

[0005] Furthermore, infrared detectors are installed on both supports via detector racks, and the two infrared detectors respectively detect the inner and outer gauges.

[0006] Furthermore, the hand-cranked adjustment component includes a connecting shaft that rotates with the two frame side plates via bearings. One end of the connecting shaft drives the lead screw on the rear side to rotate via another set of sprockets and chains, and the other end of the connecting shaft is fixed with a second handwheel.

[0007] Furthermore, the guide support is provided with a sliding through hole corresponding to the linear guide rail, and the guide support is provided with a through hole corresponding to the lead screw. The inside of the through hole is fixed with a threaded sleeve that matches the lead screw by bolts, and the guide support is also provided with a threaded hole for fixed connection with the inner guide or the outer guide.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: Firstly, when the servo motor rotates, the lead screw is driven to rotate by the sprocket and chain transmission. The rotation of the lead screw can drive the guide support to move back and forth along the linear guide rail. The guide support can drive the inner and outer guides to move, thereby automatically adjusting the positions of the inner and outer guides. For manual adjustment, turning the first handwheel can drive the servo motor to rotate, and then the lead screw is driven to rotate by the sprocket and chain transmission. The rotation of the lead screw can drive the inner guide to move, thereby manually adjusting the inner guide. Turning the second handwheel can drive the connecting shaft to rotate. When the connecting shaft rotates, it drives another lead screw to rotate by the sprocket and chain transmission. The rotation of the lead screw can drive the outer guide to move, thereby manually adjusting the outer guide. The positions of the inner and outer guides can be detected by an infrared detector. This cover manual and automatic adjustment mechanism has a simple structure and is easy to operate. It can be adjusted electrically or manually for each guide, making it more flexible to use.
