Description

Technical Field

[0001] This invention relates to the field of three-sided cutting technology for book blocks, and more particularly to a multi-sided cutting and shaping mechanism for book block processing. Background Technology

[0002] Due to the mass printing of books, three-sided book trimmers are used to ensure uniform length and width after printing. These trimmers place the book horizontally on the operating platform, using the side blades to cut the length and the front blade to cut the width. Currently, there are many three-sided book trimmers on the market. One common type has side blades and a front blade mounted on the blade holder. As the spindle moves downwards, the side blades and the front blade cut sequentially into the book, resulting in books of uniform length.

[0003] Current three-sided book trimmers typically include a book feeding device that feeds a stack of books to the cutting device; a table-mounted book alignment device that aligns the stack of books; a cutting device that cuts the sides and front of the books to ensure uniform size and creates a cutting zone; a paper pressing mechanism above the cutting zone to hold the stack of books in place and prevent shifting during cutting; and a book ejection device that removes the cut books for collection.

[0004] Since the book block needs to be cut on three sides, most three-sided book cutters fix the book, cut two sides, and then rotate the book to cut the other side. Because the position of the book is easily changed when it is rotated, the cut size will differ from the pre-measured size, resulting in poor book cutting quality. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-faceted cutting and shaping mechanism for book block processing, addressing the shortcomings of existing technologies.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows:

[0007] A multi-sided cutting and shaping mechanism for book block processing includes a positioning platform, a horizontal cutting mechanism, and a side cutting mechanism. The horizontal cutting mechanism includes a horizontal cutting blade, and the side cutting mechanism includes a side cutting blade. The horizontal cutting blade and the side cutting blade move longitudinally in sequence to approach the positioning platform to cut the side of the book.

[0008] The positioning platform is equipped with a top pressing component, a bottom support component, and a side support component. The top pressing component includes a lifting guide seat, on which a book pressing mounting component is slidably mounted, and on which a book pressing component is mounted. The book pressing component includes a fixed seat and a book pressing base detachably mounted on the fixed seat. A connecting structure is provided between the fixed seat and the book pressing base. The connecting structure includes a rotating shaft rotatably mounted on the fixed seat, an eccentric shaft mounted on the end face of the rotating shaft, and a tight-fitting hole for the book pressing base to fit tightly with the eccentric shaft. The rotating shaft can rotatably fit with the tight-fitting hole of the book pressing base.

[0009] The side support includes a pair of side positioning plates and a side positioning drive that drives the side positioning plates to move relative to each other to clamp the two sides of the book block. The side positioning plates are slidably mounted with a first pad and a second pad, wherein the first pad is mounted with a book stop block that blocks the forward direction of the book.

[0010] The cross-cutting mechanism also includes a drive blade holder and a first drive member and a first transmission member connected to the drive blade holder. The drive blade holder is equipped with the cross-cutting blade. The first drive member includes a swingable first drive arm and a drive linkage connecting the first drive arm and the drive blade holder. The first transmission member includes a swingable first transmission arm, the end of which is rotatably connected to the drive blade holder.

[0011] The beneficial effects of this invention are: when the book to be cut enters the positioning platform, the book pressing component can press the book down longitudinally through the book pressing mounting component;

[0012] When connecting the book-pressing base to the fixed base, insert the tight-fitting hole of the book-pressing base into the eccentric shaft, and then rotate the shaft to make the eccentric shaft and the hole wall of the tight-fitting hole have an interference fit, so that the book-pressing base can be tightly connected to the fixed base; when disassembling, rotate the shaft to make the eccentric shaft and the hole wall of the tight-fitting hole have a clearance fit, so that the book-pressing base can be removed from the eccentric shaft, and the disassembly and assembly can be completed. The whole process can be completed by simply rotating the shaft, which saves time and effort.

[0013] After the book is held down by the book-pressing component, the side-cutting mechanism cuts the two sides of the book. After the side-cutting is completed, when the front of the book needs to be cut, the two side positioning plates move relative to each other and move closer to the book to stop and position the side of the book. At the same time, the first and second pads fit against the side of the book to achieve positioning. In addition, the book-stopping block abuts against the rear end of the book, so that the other three sides of the book that do not need to be cut are all positioned. The positions of the first and second pads can also be adjusted according to the size of the book, which is suitable for positioning books of different sizes without disassembly.

[0014] The first drive arm of the first drive component of the cross-cutting mechanism swings back and forth longitudinally continuously. Under the transmission of the drive linkage, the drive knife holder can swing longitudinally. When the drive knife holder moves, the first drive arm of the first transmission component swings passively longitudinally, so that the cross-cutting blade installed on the drive knife holder can cut in a cycle to cut the book block. The action is continuously cycled. The transmission is carried out through a lever structure, which saves time and effort and provides sufficient power. Attached Figure Description

[0076] The present invention will now be described in detail with reference to the accompanying drawings.

[0077] like Figures 1-25 As shown, a multi-faceted cutting and shaping mechanism for core processing includes a positioning platform, a cross-cutting mechanism 5, and a side-cutting mechanism 6. The cross-cutting mechanism 5 includes a cross-cutting blade 516, and the side-cutting mechanism 6 includes a side-cutting blade 639. The cross-cutting blade 516 and the side-cutting blade 639 move longitudinally in sequence to approach the positioning platform to cut the side of the book.

[0078] The top pressing component 1 includes a lifting guide seat 11, on which a book pressing mounting component 111 is slidably mounted. The book pressing mounting component 111 is fitted with a book pressing element. It also includes a book pressing drive component 12 that drives the book pressing mounting component 111 to move longitudinally. The book pressing drive component 12 includes a book pressing swing arm that can swing longitudinally, with its other end connected to a longitudinally moving longitudinal drive arm 122. The lifting guide seat 11 has a longitudinal sliding channel for guiding the book pressing mounting component 111 to slide. The book pressing drive component 12 can be a lifting cylinder, a lifting hydraulic cylinder, or a swing arm. The drive end of the swing arm swings up and down, and the drive end is connected to the book pressing mounting component 111 via a connecting rod. The swing arm swings under the drive of a cam mechanism or a telescopic cylinder, thereby driving the book pressing mounting component 111 to press the book up and down.

[0079] The book pressing component 2 includes a fixed base 21 and a book pressing base 23 detachably mounted on the fixed base 21. A connecting structure is provided between the fixed base 21 and the book pressing base 23. The connecting structure includes a book pressing rotating shaft 212 rotatably mounted on the fixed base 21. An eccentric shaft 213 is mounted on the end face of the book pressing rotating shaft 212. The book pressing base 23 has a tight-fitting hole 233 that is tightly fitted with the eccentric shaft 213. The book pressing rotating shaft 212 can rotatably fit with the tight-fitting hole 233 of the book pressing base 23.

[0080] When it is necessary to connect the book-pressing base 23 to the fixed base 21, insert the tight-fitting hole 233 of the book-pressing base 23 into the eccentric shaft 213, and then twist the book-pressing rotating shaft 212 so that the eccentric shaft 213 and the hole wall of the tight-fitting hole 233 are interference-fitted, and the book-pressing base 23 can be tightly connected to the fixed base 21. When disassembling, twist the book-pressing rotating shaft 212 so that the eccentric shaft 213 and the hole wall of the tight-fitting hole 233 are clearance-fitted, and the book-pressing base 23 can be removed from the eccentric shaft 213 to complete the disassembly and assembly. The whole process can be completed by twisting the book-pressing rotating shaft 212, which saves time and effort.

[0081] The bottom of the fixed base 21 is formed with a book-pressing groove 216, and the top of the book-pressing base 23 is formed with a book-pressing block 231 that mates with the book-pressing groove 216. The top of the book-pressing block 231 is formed with a connecting block 232, and a tight-fitting hole 233 is formed through the connecting block 232. The eccentric shaft 213 is rotatably interference-fitted with the tight-fitting hole 233 to lift the book-pressing block 231 and insert it into the book-pressing groove 216.

[0082] In this embodiment, during installation, the book-pressing fitting block 231 of the book-pressing base 23 is placed in the book-pressing fitting groove 216 of the fixed base 21. The book-pressing fitting block 231 can slide along the book-pressing fitting groove 216 to achieve a tight lock. When locking, the book-pressing rotating shaft 212 is twisted, and the eccentric shaft 213 can rotate and be interference-fitted with the hole wall of the tight-fitting hole 233 to lift the book-pressing fitting block 231 and embed it into the book-pressing fitting groove 216, so that the book-pressing base 23 is fixed on the fixed base 21, achieving a fixed connection. During disassembly, the eccentric shaft 213 can rotate and be transition-fitted with the tight-fitting hole 233 to achieve a loosening. The book-pressing fitting block 231 slides down along the book-pressing fitting groove 216, and the book-pressing base 23 can be removed and replaced.

[0083] The connecting structure also includes a drive structure 220 that drives the book-pressing rotating shaft 212 to rotate. The drive structure 220 includes a first drive member 221 and a second drive member 225 mounted on the fixed base 21. The first drive member 221 drives the book-pressing rotating shaft 212 to rotate clockwise, and the second drive member 225 drives the book-pressing rotating shaft 212 to rotate counterclockwise. When the first drive member 221 drives the drive shaft to rotate counterclockwise, the eccentric shaft 213 can rotatably transition into the tight-fitting hole 233, achieving loosening, and the book-pressing fitting block 231 slides down along the book-pressing fitting groove 216. Similarly, when the second drive member 225 drives the book-pressing rotating shaft 212 to rotate clockwise, the eccentric shaft 213 is press-fitted into the hole wall of the tight-fitting hole 233, and the book-pressing base 23 can be tightly connected to the fixed base 21.

[0084] Specifically, a book-pressing drive seat 22 is provided on the top of the fixed base 21. The first drive member 221 and the second drive member 225 are respectively provided on the book-pressing drive seat 22. The outer ring of the book-pressing rotation shaft 212 is formed with a first contact block 214 that cooperates with the first drive member 221 and a second contact block 215 that cooperates with the second drive member 225. Through the contact and cooperation between the first contact block 214 and the second contact block 215 and the corresponding first drive member 221 and second drive member 225, the book-pressing rotation shaft 212 can rotate in the fixed base 21 to achieve an interference fit or clearance fit, so as to install or remove the book-pressing base 23.

[0085] Preferably, the included angle between the first contact block 214 and the second contact block 215 is 90°, and the first contact block 214 and the second contact block 215 are convenient to cooperate with the first driving member 221 and the second driving member 225.

[0086] Specifically, the first driving member 221 includes a book-pressing compression spring 222 installed on the book-pressing drive seat 22, and a first driving block 223 abutting against the first contact block 214 is installed at the end of the book-pressing compression spring 222. When the second driving member 225 is not working, the first driving block 223 abuts against the first contact block 214 under the elastic drive of the book-pressing compression spring 222 of the first driving member 221, so that the book-pressing rotation shaft 212 rotates clockwise, so that the eccentric shaft 213 is interference-fitted with the hole wall of the tight-fitting hole 233, so as to lift the book-pressing fitting block 231 and insert it into the book-pressing fitting groove 216, so that the book-pressing base 23 is fixed on the fixed seat 21.

[0087] Specifically, the second driving component 225 includes a telescopic cylinder 226 installed on the book pressing drive seat 22. The driving end of the telescopic cylinder 226 is equipped with a second driving block 227 that abuts against the second contact block 215. When the book pressing base 23 needs to be disassembled, the telescopic cylinder 226 operates and extends, so that the second driving block 227 abuts against the second contact block 215 and continues to extend. The power of the telescopic cylinder 226 is greater than the elastic force of the book pressing compression spring 222, pressing the second contact block 215, so that the book pressing rotating shaft 212 can rotate counterclockwise, and the eccentric shaft 213 can rotate and transition into the tight fitting hole 233 to achieve loosening. The book pressing fitting block 231 slides down along the book pressing fitting groove 216, and the book pressing base 23 can be removed and replaced.

[0088] Preferably, the book-pressing drive seat 22 has a first drive hole 224 coaxially aligned with the first contact block 214 and a second drive hole 228 coaxially aligned with the second contact block 215. The top end of the book-pressing compression spring 222 is fixed to the first drive hole 224, and the telescopic cylinder 226 is fixed to the second drive hole 228. The first drive block 223 passes through the first drive hole 224 and abuts against the first contact block 214, so that the elastic force of the book-pressing compression spring 222 can stably contact the first contact block 214. Similarly, the second drive block 227 of the telescopic cylinder 226 can pass through the second drive hole 228 and abut against the second contact block 215, driving the book-pressing rotating shaft 212 to rotate.

[0089] The fixed base 21 is formed with a drive rotation hole 211 and a first drive groove 210 communicating with the book pressing groove 216. The drive rotation hole 211 has a movable groove 219 for the first contact block 214 and the second contact block 215 to move. The movable groove 219 is connected to a first movable hole 217 coaxially aligned with the first drive hole 224 and a second movable hole 218 coaxially aligned with the second drive hole 228. When the book pressing rotation shaft 212 rotates, the first contact block 214 and the second contact block 215 swing accordingly, and the movable groove 219 formed by the drive rotation hole 211 can... The first contact block 214 and the second contact block 215 are allowed to rotate movably. The first drive block 223 passes through the first drive hole 224 and then through the first movable hole 217 to abut against the first contact block 214, so that the elastic force of the book-pressing compression spring 222 can stably contact the first contact block 214. Similarly, the second drive block 227 of the telescopic cylinder 226 can pass through the second drive hole 228 and then through the second movable hole 218 to abut against the second contact block 215, driving the book-pressing rotating shaft 212 to rotate, further improving the activity stability of the first drive block 223 and the second drive block 227.

[0090] The connecting block 232 of the book pressing fitting block 231 is in the first drive groove 210, and its tight fitting hole 233 is basically coaxially aligned with the drive rotation hole 211. The book pressing rotation shaft 212, which is rotatably installed in the drive rotation hole 211, drives the eccentric shaft 213 to rotate. The eccentric shaft 213 passes through the tight fitting hole 233 and can be interference-fitted with the tight fitting hole 233 to fit and fix the book pressing base 23 in the book pressing fitting groove 216. Alternatively, it can rotatably drive the eccentric shaft 213 to have a clearance fit with the tight fitting hole 233. At this time, the book pressing base 23 can be removed and disassembled from the eccentric shaft 213.

[0091] The bottom support 3 includes a support base plate 31 for positioning the book and a positioning base 314 for mounting the support base plate 31. The support base plate 31 has a snap-fit ​​groove 313. The positioning base 314 is equipped with a swingable mounting arm 321. The mounting arm 321 is equipped with a snap-fit ​​block 323 that cooperates with the snap-fit ​​groove 313. The mounting arm 321 can swing and fasten the support base plate 31 to the positioning base 314 by snapping the snap-fit ​​groove 313 with the snap-fit ​​block 323.

[0092] The support base plate 31 for supporting the book is placed on the positioning base 314, so that the snap-fit ​​groove 313 is close to the snap-fit ​​block 323. Then, the mounting arm 321 is swung, and the snap-fit ​​block 323 at the end of the mounting arm 321 hooks the snap-fit ​​groove 313 at the bottom of the support base plate 31, so that the snap-fit ​​block 323 and the snap-fit ​​groove 313 stop and cooperate, and the support base plate 31 can be fixed to the positioning base 314. The disassembly is convenient and the steps are simple, eliminating the need for bolt connection structure.

[0093] Preferably, the bottom of the support base plate 31 is formed with a first fitting groove 311, and a first fitting block 312 flush with the bottom surface of the support base plate 31 is installed in the first fitting groove 311. A snap-fit ​​groove 313 is formed in the first fitting block 312. The first fitting block 312 is installed in conjunction with the first fitting groove 311, and the snap-fit ​​groove 313 is formed in the first fitting block 312. The support base plate 31 can stop and cooperate with the snap-fit ​​block 323 through the first fitting groove 311 and the snap-fit ​​groove 313.

[0094] Preferably, the groove wall of the snap-fit ​​groove 313 is inclined. After the inclined surface is formed, the groove wall of the snap-fit ​​groove 313 forms an angle with the first fitting groove 311. The snap-fit ​​block 323 is also an inclined structure. After the snap-fit ​​block 323 swings, it locks the groove wall of the snap-fit ​​groove 313 and the first fitting groove 311 to form an angle structure, thereby achieving a tight fit.

[0095] Specifically, the top of the positioning base 314 is formed with a contact top plate 315 that contacts the bottom surface of the support base plate 31. The contact top plate 315 has a driving cavity 316. The top of the driving cavity 316 has a top groove 317. The mounting arm 321 is oscillatingly mounted in the driving cavity 316. The mounting arm 321 oscillates and drives the buckle block 323 to pass through the top groove 317 and stop with the buckle groove 313 of the support base plate 31.

[0096] Preferably, the drive cavity 316 is equipped with a mounting drive shaft 322 for the mounting arm 321 to swing. The bottom of the drive cavity 316 is provided with a bottom groove 318. The bottom of the mounting arm 321 is rotatably connected to a longitudinally moving lifting rod 324. The bottom of the lifting rod 324 extends outward through the bottom groove 318. The lifting rod 324 can move in the vertical direction, causing the mounting arm 321 to swing around the mounting drive shaft 322. The latching block 323 at the top of the mounting arm 321 can pass through the top groove 317 to latch onto the support base plate 31 located on the positioning base 314. When disassembly is required, the mounting arm 321 swings in another direction, so that the latching block 323 can swing outward and disengage from the latching groove 313. At this time, the support base plate 31 can be disassembled from the positioning base 314.

[0097] A lifting drive mechanism 32 is provided below the positioning base 314. The lifting drive mechanism 32 includes a bottom drive seat 325 and a drive cylinder 326 that is swayably mounted on the bottom drive seat 325. The piston rod 327 of the drive cylinder 326 is coaxially connected to the lifting rod 324. When the piston rod 327 of the drive cylinder 326 extends, it drives the mounting arm 321 to swing outward around the mounting drive shaft 322 through the lifting rod 324, so that the latching block 323 can swing outward and disengage from the latching groove 313. At this time, the support base plate 31 can be removed from the positioning base 314. Similarly, when the piston rod 327 of the drive cylinder 326 retracts, it drives the mounting arm 321 to swing inward around the mounting drive shaft 322 through the lifting rod 324, so that the latching block 323 can swing inward. The latching block 323 passes through the top groove 317 and stops with the latching groove 313 of the support base plate 31.

[0098] Waste hoppers 33 for filling waste materials are respectively provided on both sides of the support base plate 31. The waste hoppers 33 are arranged at an inclination and have a through opening 332 for waste material discharge.

[0100] Preferably, the adjusting shaft 333 is a lead screw.

[0101] In this embodiment, by rotating the adjusting shaft 333, the sliding adjusting seat 335 is threadedly engaged with the adjusting shaft 333 through the transverse adjusting hole 336, and the sliding adjusting seat 335 slides along the adjusting guide shaft 334, thereby adjusting the position of the waste hopper 33.

[0102] The side support member 4 includes a pair of side positioning plates 41 and a side positioning drive member 43 that drives the side positioning plates 41 to move relative to each other to clamp the two sides of the book block. The side positioning plates 41 are slidably mounted with a first pad 412 and a second pad 413, wherein the first pad 412 is mounted with a book stop block 416 that stops the book from moving forward.

[0103] The book that needs to be cut enters the cutting station. At this time, the two side positioning plates 41 move relative to each other and move closer to the book to stop and position the side of the book. At the same time, the first pad 412 and the second pad 413 are in contact with the side of the book to achieve positioning. In addition, the book stop block 416 abuts against the rear end of the book so that the other three sides of the book that do not need to be cut are positioned. The positions of the first pad 412 and the second pad 413 can also be adjusted according to the size of the book. It is suitable for positioning books of different sizes and does not require disassembly.

[0104] The side positioning plate 41 is provided with a position adjustment mechanism 42 that drives the first pad 412 and the second pad 413 to slide. The side positioning plate 41 is provided with an adjustment track 411 along its length. The first pad 412 and the second pad 413 are respectively provided with track grooves 414 that slide along the adjustment track 411. The first pad 412 and the second pad 413 can slide through the cooperation of the track grooves 414 and the adjustment track 411, thereby changing the position of the first pad 412 and the second pad 413. The position of the book stop block 416 changes, which can be used to adapt to books of different sizes.

[0105] Preferably, the first pad 412 is located inside the second pad 413, and the second pad 413 is equipped with a flared plate 415 for guiding the book into the side positioning plate 41, making it easier for the book to enter between the side positioning plates 41.

[0106] Preferably, the cross-sectional shape of both the track groove 414 and the adjusting track 411 is trapezoidal, which can prevent the first pad 412 and the second pad 413 from falling off the adjusting track 411.

[0107] Specifically, the position adjustment mechanism 42 includes an adjustment screw 421 parallel to the adjustment track 411. The first pad 412 and the second pad 413 each include an adjustment sliding seat 417. The adjustment sliding seat 417 has an adjustment hole 418 coaxially aligned with the adjustment screw 421. The side positioning plate 41 is equipped with an adjustment gear 422 that is drively connected to the adjustment screw 421. In this embodiment, when the positions of the first pad 412 and the second pad 413 need to be adjusted, the adjustment screw 421 is rotated by rotating the adjustment gear 422. When the adjustment screw 421 rotates, the first pad 412 and the second pad 413 are threadedly engaged with the adjustment screw 421 through the adjustment hole 418 of the adjustment sliding seat 417, and the positions of the first pad 412 and the second pad 413 can change. The position of the book block 416 installed on the first pad 412 changes accordingly.

[0108] The position adjustment mechanism 42 also includes a guide sleeve 425 and a transmission guide shaft 423 slidably mounted on the guide sleeve 425. One end of the transmission guide shaft 423 is fitted with a first drive gear 424 that meshes with the adjustment gear 422. The guide sleeve 425 is fitted with a drive gear 426. An anti-slip groove 427 is formed on the inner wall of the guide sleeve 425, and an anti-slip protrusion 428 is formed on the outer wall of the transmission guide shaft 423 that cooperates with the anti-slip groove 427. In this embodiment, since the side positioning plate 41 moves relative to the other side, to ensure adjustment stability, the side positioning plate 41... During operation, the transmission guide shaft 423 moves within the guide sleeve 425. The transmission guide shaft 423 and the guide sleeve 425 are engaged by the anti-slip groove 427 and the anti-slip protrusion to restrict the radial movement of the transmission guide shaft 423 within the guide sleeve 425 and prevent slippage. The guide sleeve 425 is connected to the drive motor via the drive gear 426. When the guide sleeve 425 rotates, the transmission guide shaft 423 rotates accordingly. The positions of the first pad 412 and the second pad 413 are adjusted by the meshing of the first drive gear 424 and the adjusting gear 422.

[0109] The side positioning drive 43 includes a transmission drive plate 435 connected to the side positioning plate 41 and a rocker drive that drives the transmission drive plate 435 to move along the clamping motion direction of the side positioning plate 41. Under the drive of the rocker drive, the transmission drive plate 435 moves back and forth accordingly, so that the side positioning plate 41 can move closer to or further away from the book to clamp and position the side of the book.

[0110] Specifically, the rocker drive includes a first rocker drive 431 and a second rocker drive 44. The first rocker drive 431 includes a first rocker 432 arranged perpendicular to the transmission drive plate 435 and a first connecting rod 433 rotatably connected to the first rocker 432. A connecting rod 434 is nested at the end of the first connecting rod 433. The connecting rod 434 is connected to the second rocker drive 44. The first rocker 432 swings longitudinally, causing the first connecting rod 433 to move laterally with an arc, transmitting power to the second rocker drive mechanism.

[0111] Preferably, the first rocker arm 432 swings longitudinally in a reciprocating motion driven by the cam mechanism 436.

[0112] The second rocker drive component 44 includes a second rocker component 441 capable of lateral swing. The driven end of the second rocker component 441 is nested with a movable roller 445 that is movably connected to the transmission drive plate 435. The driving end of the second rocker component 441 is movably connected to a longitudinally arranged second connecting rod 442. The bottom of the second connecting rod 442 is fixed to the connecting rod 434. Under the drive of the first connecting rod 433, the connecting rod 434 rotates and continues to transmit the rotation to the second rocker component 441.

[0113] Specifically, the second connecting rod 442 has a top movable hole 443, and a transverse rod 444 is movably nested in the top movable hole 443. The other end of the transverse rod 444 is rotatably connected to the active end of the second rocker member 441. The bottom end of the second connecting rod 442 is fixed on the connecting rod 434. The second connecting rod 442 swings longitudinally accordingly. The transverse rod 444 is provided between the second connecting rod 442 and the active end of the second rocker member 441 for movable connection. At this time, the longitudinal swing becomes the transverse swing, and the second rocker member 441 swings transversely around the fulcrum end. The driven end of the second rocker member 441 is movably connected to the transmission drive plate 435 through the movable roller 445, thereby driving the side positioning plate 41 to move.

[0114] Preferably, the side positioning drive member 43 further includes a top mounting plate 447 for mounting the fulcrum end of the second rocker member 441. When the second rocker member 441 swings, it swings around the fulcrum end mounted on the top mounting plate 447. The swing direction of the driven end movable roller 445 is arc-shaped. The transmission drive plate 435 has a movable long groove 446 along its width direction. The movable long groove 446 guides the movable roller 445 of the driven end of the second rocker member 441 to roll. The movable long groove 446 allows the movable roller 445 to roll.

[0115] Preferably, the top mounting plate 447 is equipped with two or more rows of guide rollers 448, and the long sides of the transmission drive plate 435 are respectively in rolling engagement with the guide rollers 448, so that when the transmission drive plate 435 moves, it can be in rolling engagement with the guide rollers 448, thereby improving its sliding stability and enabling it to move back and forth in a straight line.

[0116] Furthermore, there are two side positioning drive members 43, which are respectively connected to the corresponding side positioning plates 41. The cam mechanism 436 used to drive the first rocker arm 432 to swing is connected to the large gear 437. The large gears 437 of the two side positioning drive members 43 are connected through the drive shaft, so that the two side positioning drive members 43 move at the same time and the two side positioning plates 41 can move closer or further away at the same time.

[0117] The top pressing member 1, with the book pressing member 2 installed, presses down to press the top surface of the book, and the bottom support member 3 supports its bottom surface, making it less prone to displacement when cutting the sides of the book. In addition, when it is necessary to cut the front side of the book, the top pressing member 1, with the book pressing member 2 installed, presses down to press the top surface of the book, and the bottom support member 3 supports its bottom surface. The two side positioning plates 41 of the side support member 4 move relative to each other and move closer to the book to stop and position the side of the book. At the same time, the first pad 412 and the second pad 413 are in contact with the side of the book to achieve positioning. In addition, the book stop block 416 abuts against the rear end of the book, so that the other three sides of the book that do not need to be cut are all positioned.

[0118] The cross-cutting mechanism 5 includes a drive blade holder 51, on which a cross-cutting blade 516 is mounted. It also includes a longitudinally swinging first drive member 52 and a first transmission member 53. The first drive member 52 includes a swingable first drive arm 521 and a drive linkage 535 connecting the first drive arm 521 and the drive blade holder 51. The first transmission member 53 includes a swingable first transmission arm 532, the end of which is rotatably connected to the drive blade holder 51.

[0119] The first drive arm 521 of the first drive member 52 swings back and forth longitudinally continuously. Under the transmission of the drive link 535, the drive knife holder 51 can swing longitudinally. When the drive knife holder 51 moves, the first transmission arm 532 of the first transmission member 53 swings longitudinally passively, so that the cross-cutting blade 516 installed on the drive knife holder 51 can cut the book core in a cyclic manner. The action is continuously cyclical. The transmission is carried out through the lever structure, which saves time and effort and provides sufficient power.

[0120] Preferably, the cross-cutting mechanism 5 further includes a support column 531 for mounting the first drive arm 521, and the first drive member 52 further includes a longitudinally moving drive rod 536. The top of the drive rod 536 is rotatably connected to the first drive arm 521. The first drive arm 521 is swayably mounted on the support column 531. Under the lifting and retracting reciprocating motion of the drive rod 536, the first drive arm 521 can swing back and forth, so that the cross-cutting blade 516 mounted on the drive blade holder 51 can cut the book core in a cyclic manner. The action is continuously cyclical. The transmission is achieved through a lever structure, which saves time and effort and provides sufficient power.

[0121] Preferably, the drive rod 536 is driven by a cam mechanism to perform lifting and lowering movements.

[0122] Preferably, the first drive arm 521 includes a rotating end 522 rotatably mounted on the support column 531, a drive end 520 rotatably connected to the drive rod 536, and a transmission end 529 rotatably connected to the drive link 535. The rotating end 522 is the fulcrum, and the first drive arm 521 swings around the rotating end 522. The drive end 520 is driven to swing by the drive rod 536, and the transmission end 529 drives the drive link 535 to move, so that the drive tool holder 51 can move.

The transmission end 529 is formed with a transmission groove 527, and the transmission groove 527 is equipped with a transmission shaft 528 that is connected to the drive connecting rod 535.

[0124] In this embodiment, the driving end 520 of the first driving arm 521 is connected to the driving rod 536 via a driving shaft 526. The first driving arm 521 is connected to the transverse rotating shaft 524 of the support column 531 via a transverse rotating hole 523. The first driving arm 521 can swing, and the angle between the driving rod 536 and the first driving arm 521 will change. The second driving groove 525 can accommodate the driving rod 536. Similarly, the angle between the transmission end 529 of the first driving arm 521 and the driving link 535 will change. The driving link 535 is connected to the transmission end 529 of the first driving arm 521 via a transmission shaft 528. When the swing reaches a small angle between the transmission end 529 and the driving link 535, the transmission groove 527 can accommodate the driving link 535.

[0125] The first transmission member 53 includes a pair of swingable first transmission arms 532, each first transmission arm 532 having the same angle with the drive tool holder 51, that is, the two first transmission arms 532 are arranged in parallel.

[0126] Preferably, the top ends of one or both first drive arms 532 are rotatably mounted on the support column 531.

[0127] A transmission block 533 is installed at the top of the support column 531. The transmission block 533 is equipped with a top shaft 534 for one of the first transmission arms 532 to rotate. One end of the first transmission arm 532 can swing around the top shaft 534 of the transmission block 533, and the other end is connected to the drive tool holder 51. When the drive tool holder 51 swings, the first transmission arm 532 has a limiting effect to prevent the drive tool holder 51 from falling.

[0128] Preferably, the top of the drive tool holder 51 is formed with a first movable groove 511, and a first movable shaft 512 connected to the first transmission arm 532 is installed in the first movable groove 511. The first transmission arm 532 is installed in the first movable groove 511 of the drive tool holder 51 through the first movable shaft 512. When the drive tool holder 51 moves, the angle between it and the first transmission arm 532 will change. When the angle decreases, a part of the first transmission arm 532 can be accommodated in the first movable groove 511 for the drive tool holder 51 to move normally.

[0129] Preferably, the bottom of the drive tool holder 51 is formed with a second movable groove 513. The second movable groove 513 is equipped with a second movable shaft 514 connected to the drive connecting rod 535. The drive connecting rod 535 is installed in the second movable groove 513 of the drive tool holder 51 through the second movable shaft 514. When the drive tool holder 51 moves, the angle between it and the drive connecting rod 535 will change. When the angle decreases, a part of the drive connecting rod 535 can be accommodated in the second movable groove 513 for the drive tool holder 51 to move normally.

[0130] The bottom of the drive blade holder 51 is also formed with a blade mounting groove 515 for mounting a cross-cutting blade 516. The cross-cutting blade 516 can be detachably mounted in the blade mounting groove 515 by means of bolts or other mounting structures, and different cross-cutting blades 516 can be used to cut books of different sizes and thicknesses.

[0131] The side-cutting mechanism 6 includes a fixed shaft 637 and a cutting blade holder 638 nested in the fixed shaft 637. The cutting blade holder 638 is equipped with a side-cutting blade 639 for cutting books. It also includes a cutting transmission mechanism 61 that drives the fixed shaft 637 to perform an arc-shaped swinging motion. The cutting transmission mechanism 61 includes a swing drive seat 611 connected to the fixed shaft 637 and a swing arm 62 with one end movably connected to the swing drive seat 611. The swing arm 62 performs a longitudinal arc-shaped swinging motion to drive the fixed shaft 637 to reciprocate in an arc-shaped vertical direction.

[0132] The cutting blade holder 638 is mounted on the fixed shaft 637 and swings in an arc shape on the swing arm 62. The end of the swing arm 62 is movably connected to the swing drive seat 611. When the swing arm 62 moves, the swing drive seat 611 will move downward in an inclined direction in the vertical direction. The side cutting blade 639 of the cutting blade holder 638 cuts at an angle. With the same feed rate, the strain energy overcome by the oblique cutting is less than that of the straight cutting. The extrusion force on both sides of the blade is small, and the friction is also small, which is beneficial for cutting and can protect the blade.

[0133] The cutting transmission mechanism 61 also includes a pair of spaced-apart column plates 612, each column plate 612 being equipped with a swing drive component that drives the swing arm 62 to reciprocate. The swing drive component includes a rotatable drive shaft 615 and a cam block 617 mounted on one end of the drive shaft 615. A swing transmission arm 621 is connected between the cam block 617 and the swing arm 62. The drive shaft 615 rotatably drives the cam block 617 to rotate, and one end of the swing transmission arm 621 is movably nested on the cam block 617, allowing the swing transmission arm 621 to reciprocate, thereby driving the swing arm 62 to perform a corresponding reciprocating arc swing motion.

[0134] The column plate 612 has a horizontal swing drive hole 613. A drive frame 614 is installed on the outside of the swing drive hole 613. The drive frame 614 is equipped with a bearing seat 618 for the drive shaft 615 to rotate. A second drive gear 16 is installed on the outer end of the drive shaft 615. The second drive gear 16 rotates under the drive of the motor, thereby driving the drive shaft 615 to rotate around the bearing seat 618 in the drive frame 614. The cam block 617 is located inside the column plate 612.

[0135] The cam block 617 is equipped with a first rotating shaft 622. One end of the swing transmission arm 621 is movably nested in the first rotating shaft 622. A second rotating shaft 623 is installed near the midpoint of the swing arm 62. The other end of the swing transmission arm 621 is movably nested in the second rotating shaft 623. One end of the swing transmission arm 621 is movably connected to the first rotating shaft 622 of the cam block 617, and the other end is movably connected to the second rotating shaft 623 of the swing arm 62. When the cam block 617 rotates, it drives the swing arm 62 to swing back and forth through the swing transmission arm 621.

[0136] One end of the swing transmission arm 621 is formed with a first limiting groove 624. The first limiting groove 624 has a first rotating hole 625 for installing the second rotating shaft 623. The width of the first limiting groove 624 is greater than the width of the swing arm 62. When the swing arm 62 is connected to the swing transmission arm 621, the swing trajectory of the swing arm 62 is vertical under the limitation of the first limiting groove 624.

[0137] The column plate 612 is equipped with a third rotating shaft 626. The bottom end of the swing arm 62 is rotatably connected to the third rotating shaft 626. The swing arm 62 swings longitudinally around the third rotating shaft 626. The swing drive seat 611 is equipped with a fourth rotating shaft 627. The top end of the swing arm 62 is rotatably connected to the fourth rotating shaft 627. In this embodiment, the swing transmission arm 621 drives the swing arm 62 to swing, so that the bottom end of the swing arm 62 swings around the third rotating shaft 626. The top end of the swing arm 62 drives the swing drive seat 611 to move through the fourth rotating shaft 627, so that the movement trajectory of the swing drive seat 611 is the swing trajectory of the outer end of the swing arm 62.

[0138] The swing drive base 611 is formed with a drive connecting block 630, and the drive connecting block 630 is formed with a second limiting groove 632. The second limiting groove 632 has a second rotating hole 633 for installing the fourth rotating shaft 627. The width of the second limiting groove 632 is greater than the width of the swing arm 62. Similarly, under the limitation of the second limiting groove 632, the top of the swing arm 62 will not move laterally beyond the width range of the second limiting groove 632 and will remain in the vertical direction. Under the limiting action of the first limiting groove 624 and the second limiting groove 632, the swing arm 62 can ensure the stability of the movement trajectory and improve the smoothness of the swing.

[0139] The column plate 612 is equipped with a fulcrum seat 63, and the fulcrum seat 63 is equipped with a swingable guide arm 631. The other end of the guide arm 631 is movably connected to the swing drive seat 611 to limit the movement of the guide arm 631 within the range of the outer end movement trajectory. The guide arm 631 is for transmission. When the swing drive seat 611 makes an arc swinging motion, the top end of the guide arm 631 moves accordingly, and the guide arm 631 swings around the fulcrum seat 63 at the bottom end.

[0140] The swing drive seat 611 is also equipped with a rolling guide plate 634, and the rolling guide plate 634 is equipped with a second guide roller 635. The inner side wall of the column plate 612 is arranged with a side roller plate 636 that rolls with the second guide roller 635 along the movement direction of the fixed shaft 637. When the swing drive seat 611 makes an inclined arc movement in the vertical direction, the second guide roller 635 installed on the rolling guide plate 634 will roll along the side roller plate 636, so that the inner side wall of the swing drive seat 611 is not easily deviated laterally under the limitation of the second guide roller 635 and the side roller plate 636, which can improve the stability of movement.

[0141] The cutting blade holder 638 has a connecting seat 711 formed therein, and a nesting hole 712 is formed in the connecting seat 711. The side cutter 639 is installed in the cutting blade holder 638. The clamping structure 7 includes a nesting hole 712 formed in the connecting seat 711 and connected to the fixed shaft 637, as well as a first locking protrusion 713 and a second locking protrusion 714 that adjust the tightness between the connecting seat 711 and the fixed shaft 637. An elastic clamping member 721 that is close to each other and a drive spreading member 722 that is far away from each other are provided between the first locking protrusion 713 and the second locking protrusion 714.

[0142] The connecting seat 711 is connected to the fixed shaft 637 through the nesting hole 712, so that the connecting seat 711 can be fixed. When fixed, the first locking protrusion 713 and the second locking protrusion 714 are spread apart and brought closer to each other by the elastic clamping member, so that the connecting seat 711 can be tightly fitted with the fixed shaft 637 through the nesting hole 712, which is not easy to separate and maintains tight pressure. When it is necessary to disassemble, the first locking protrusion 713 and the second locking protrusion 714 are moved away from each other by the driving opening member 722, thereby achieving separation and disassembly is simple.

[0143] The connecting seat 711 is axially formed with an adjustable opening 717 that can adjust the size of the nesting hole 712. The first locking protrusion 713 and the second locking protrusion 714 are arranged at intervals. When the first locking protrusion 713 and the second locking protrusion 714 are close to each other, the width of the adjustable opening 717 decreases, which can achieve a tight fit. Conversely, when the first locking protrusion 713 and the second locking protrusion 714 are far apart from each other, the width of the adjustable opening 717 increases, and the connecting seat 711 can be loosened from the fixed shaft 637 for adjustment.

[0144] A clamping guide shaft 72 is provided between the first locking protrusion 713 and the second locking protrusion 714. One end of the clamping guide shaft 72 extends toward the top of the first locking protrusion 713. The first locking protrusion 713 and the second locking protrusion 714 are respectively coaxially formed with guide drive holes 729 that are coaxially aligned with the clamping guide shaft 72. The bottom of the clamping guide shaft 72 is fixed to the second locking protrusion 714. The first locking protrusion 713 can move along the clamping guide shaft 72 through the guide drive hole 729. The clamping guide shaft 72 allows the first locking protrusion 713 and the second locking protrusion 714 to be slidably clamped or disassembled along the clamping guide shaft 72.

[0145] A stop sleeve 724 is installed on the top of the clamping guide shaft 72. The elastic clamping member 721 includes multiple elastic pressure plates 723 nested in a stacked manner on the top of the clamping guide shaft 72. The multiple stacked elastic pressure plates 723 are located between the stop sleeve 724 and the first locking protrusion 713 to elastically drive the first locking protrusion 713 closer to the second locking protrusion 714. The elastic pressure plates 723 have the effect of elastic deformation. The multiple stacked elastic pressure plates 723 continuously expand and press down the first locking protrusion 713, continuously approaching the second locking protrusion 714, so that the width of the adjustable opening 717 of the nesting hole 712 is reduced. Under a large elastic pressure, the connecting seat 711 and the fixed shaft 637 are clamped together.

[0146] Preferably, the top of the clamping guide shaft 72 is formed with an external thread structure 372. A threaded sleeve 725 is installed by rotating the external thread structure 372. A stop sleeve 724 is located at the bottom of the threaded sleeve 725. When the connecting seat 711 is clamped onto the fixed shaft 637, the elastic pressure plate 723 is nested in the clamping guide shaft 72 through the hole, stacked layer by layer. Then, the elastic pressure plate 723 is fixed to the top of the clamping guide shaft 72 by the threaded sleeve 725 and the stop sleeve 724. The elastic pressure plate 723 can be compressed by continuously rotating the threaded sleeve 725. Under the strong elastic drive, the first locking protrusion 713 continuously presses down along the clamping guide shaft 72 and approaches the second locking protrusion 714, so that the width of the adjustable opening 717 of the nesting hole 712 is reduced, and the connecting seat 711 and the fixed shaft 637 are clamped.

[0147] When disassembly is required, the drive support 722 includes a hydraulic cylinder 726 arranged between the first locking protrusion 713 and the second locking protrusion 714. The bottom of the hydraulic cylinder 726 is mounted on the second locking protrusion 714. The drive end of the hydraulic cylinder 726 extends to push the first locking protrusion 713 away from the second locking protrusion 714. The drive end of the hydraulic cylinder 726 extends and abuts against the bottom of the first locking protrusion 713. The strong thrust compresses the multiple stacked elastic pressure plates 723, which increases the width of the adjustable opening 717 of the nesting hole 712. The nesting hole 712 becomes loose from the fixed shaft 637, and the lateral position of the adjustable connecting seat 711 is adjusted.

[0148] Preferably, a third drive block 727 is installed at the drive end of the hydraulic cylinder 726. The third drive block 727 has a movable guide hole 728 for the clamping guide shaft 72 to pass through, so that the third drive block 727 at the drive end of the hydraulic cylinder 726 can slide along the clamping guide shaft 72. The third drive block 727 can abut against the first locking protrusion 713, causing the first locking protrusion 713 to be pushed upward and away from the second locking protrusion 714.

[0149] The connecting seat 711 has a first fitting groove 715 for mounting a first locking protrusion 713 and a second fitting groove 716 for mounting a second locking protrusion 714. The first fitting groove 715 and the second fitting groove 716 are aligned in the vertical direction. The first locking protrusion 713 is mounted on the connecting seat 711 through the first fitting groove 715. The second locking protrusion 714 is mounted on the connecting seat 711 through the second fitting groove 716.

[0150] The first locking protrusion 713 has a guide hole 718 in the longitudinal direction. The guide hole 718 can be height-adjusted to install a limit rod 719. When multiple stacked elastic pressure plates 723 are continuously expanded, the first locking protrusion 713 will continuously approach the second locking protrusion 714. The limit rod 719 can prevent the first locking protrusion 713 from damaging the hydraulic cylinder 726, which would prevent it from being expanded in the future.

[0151] In summary, the present invention possesses the excellent characteristics described above, which enhances its effectiveness in use compared to previous technologies, making it a highly practical product.

[0152] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
