TECHNICAL FIELD

[0001] The present application relates to the technical field of book block cutting equipment, in particular to a positioning platform of book block cutting equipment. BACKGROUND

[0002] Due to the mass printing of books, in order to facilitate the printing of a large number of books, ensure the consistency of the length and width, a three-side book cutting machine is usually used, which places the books on the operation platform, cuts the length of the books by two side knives of the three-side book cutting machine, and cuts the width of the books by a front knife. There are many types of three-side book cutting machines on the market, and the most commonly used three-side book cutting machine is to install side knives and a front knife on a knife holder, when the main shaft moves downward, the two side knives and the front knife cut the books in turn to form books with consistent specifications. Whether the cutting size of the books meets the specifications and whether the cut is smooth are the standards for measuring the cutting quality of the three-side book cutting machine.

[0003] On the market, the three-side book cutting machine develops rapidly, because it can process three surfaces of the books at the same time, greatly saves time and reduces the process, improves the processing efficiency, and is widely used in production. In order to further improve the production efficiency, multiple books are often stacked and cut during production. However, when the existing three-side book cutting machine cuts multiple books stacked together, the books often cannot be aligned, which makes it difficult to ensure the consistency of the book size during the cutting of multiple books stacked together, and affects the quality of the books.

[0067] Preferably, the bottom end of the longitudinal driving arm 122 can be in rolling fit with the cam block to realize lifting; or the lifting can be realized by driving of a telescopic hydraulic cylinder.

[0068] The buffer driving member 13 comprises a resilient driving block 131 installed at the outer end of the swing arm plate 121 and a swingable swing driving arm 14, and the swing driving arm 14 is provided with an active connecting rod member 128 in active connection with the book pressing mounting member 11 at the inner end. When the swing arm plate 121 swings, the positions of the swing arm plate 121 and the swing driving arm 14 installed at the swing arm plate 121 change, and the active connecting rod member 128 can drive the second connecting sleeve 116 to lift.

[0069] The first mounting plate 132 is mounted on one end of the swing arm plate 121, the elastic driving block 131 comprises a first guide shaft 133 fixed on one end of the first mounting plate 132 and a buffer block 134 slidably mounted on the first guide shaft 133, and the first mounting plate 132 is further provided with a compression spring 135 abutting against the buffer block 134.

[0070] In the embodiment, when the outer end of the swing arm plate 121 descends, the arc-shaped groove 126 at the inner end will ascend around the third rotating shaft 125, and at this time, the inner end of the swing driving arm 14 will drive the second connecting sleeve 116 to ascend through the movable connecting link 128; conversely, when the outer end of the swing arm plate 121 ascends, the arc-shaped groove 126 at the inner end will descend around the third rotating shaft 125, and at this time, the inner end of the swing driving arm 14 will drive the second connecting sleeve 116 to descend to press and position the book, and when the book is pressed and positioned, the buffer block 134 will be compressed along the first guide shaft 133 in which the compression spring 135 is nested, so that the second connecting sleeve 116 has a buffering effect when descending, i.e., the pressing of the book is elastic, which can prevent the book from being damaged by pressing.

[0071] Preferably, the top and bottom of the buffer block 134 are respectively formed with rolling surfaces 136 in the length direction, the swing arm plate 121 is mounted with a plurality of guide rolling wheels 137 in rolling cooperation with the rolling surfaces 136, and when the buffer block 134 slides, the rolling surfaces 136 are in rolling cooperation with the guide rolling wheels 137, so that the buffer block 134 can move axially along the first guide shaft 133,

The outer end of the first buffer arm 141 is in rolling engagement with the buffer block 134 through the buffer rolling wheel 143. When the outer end of the swing arm plate 121 descends, the second buffer arm 142 drives the movable connecting rod 128 to swing upward around the third rotating shaft 125, so that the second connecting sleeve 116 can be lifted. Similarly, when the outer end rises, the second buffer arm 142 drives the movable connecting rod 128 to swing downward around the third rotating shaft 125, so that the second connecting sleeve 116 can descend to press the book. When descending, the outer end of the first buffer arm 141 is in rolling engagement with the buffer block 134 through the buffer rolling wheel 143, which has a buffer elastic effect.
