Problems solved by technology
The disadvantages of the first method are: waste of human resources, slow turning speed, and high labor intensity; the disadvantages of the second method are: this mechanism is greatly affected by the weight of the book block and the size of the format, and the speed of the machine cannot be too fast, because the book block needs to be crawled. Slope, thereby increasing the length of the machine, high failure rate such as jamming; the disadvantage of the third method is: the pendulum swings back and forth once, only one book block can be turned over, and the empty stroke cannot be overcome, and the turning efficiency is low

Embodiment Construction
[0013] The present invention will be further described in detail below in conjunction with the drawings.
[0014] A new type of book block turning mechanism, including turning shaft 1, said turning shaft 1 is rotatably connected to the frame through a bearing, said turning shaft 1 is fixed with two outer rotating brackets 3 through a tension sleeve flat key The outer rotating bracket 3 is connected by a long connecting shaft 12, and both ends are locked and fixed by nuts. The outer rotating bracket 3 is fixed with an upper fixing plate 6, an upper clamping splint 8, and a clamping cylinder 10. , The upper fixing plate 6, the upper clamping clamp plate 8, and the clamping cylinder 10 form a set of oscillating bodies and rotate and oscillate together with the turning shaft 1. The turning shaft 1 is provided with a sleeve 5, and the shaft The sleeve 5 is equipped with a bearing. The shaft on the turning shaft 1 uses an elastic retaining ring to prevent the bearing from moving axiall...

The invention discloses a novel bookblock overturning mechanism. The mechanism is fixed to a book running channel through a screw and is treated as part of the book running channel; a power shaft anda main machine power shaft are connected to transfer power to a cam which is capable of controlling the overturning mechanism to swing in a reciprocating manner; as the cam rotates, a swinging rod reciprocates and pulls two clamping plate sets; each clamping plate set positively works and swings once within each swinging circle of the swinging rod, and the swinging times in the positive working complements each other, so that the idle stroke of each clamping set in swinging is filled; and a cylinder for clamping and releasing a bookblock is mounted on each clamping plate. With the adoption ofthe mechanism, a 16-leaf bookblock can be overturned, and bookblock of eight-leaf test paper can also be overturned, so that the problems of high working intensity and low speed of purely manual overturning or unreliability and low efficiency of other overturning modes can be completely solved. The mechanism has the advantages of being simple in structure, compact, stable and reliable to move, quick, and high in efficiency.
Description
Technical field [0001] The invention relates to the technical field of book block turning mechanisms of perfect binding machines, in particular to a novel book block turning mechanism. Background technique [0002] There are three methods for the book block turning mechanism of the existing perfect binding equipment. The first method is to manually flip the book block by the operator and then complete the perfect binding; the second method is to make the book block climb by the conveying device and wait for the book block to climb to a certain height. , Utilizing the height difference and the gravity of the book block itself, the book block can be turned over in a free fall mode; the third method is to drive a set of splint mechanism by a cam drive a swing rod, the splint clamps the book block and flips, the splint loosens, and the book block enters The perfect binding machine completes subsequent perfect binding. The shortcomings of the first method are: waste of human resource...
