Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of notebook cutting, and more particularly to a notebook strip cutting device. BACKGROUND

[0002] In daily life, there are situations that need to record by using words or pictures, at this time, notebooks are needed. The common method of making notebooks is to punch in the middle of the stacked paper, and then fold the pages, that is, fold along the middle, so as to form a notebook. After the notebook is made, it needs to be cut to make the edges of the notebook neat. In order to improve production efficiency, multiple notebooks are often produced together, and then the edges are trimmed and cut into single notebooks after the pages are arranged and bound.

[0003] A notebook cutting machine with application number "201811286654.X" proposes a device that cuts and divides notebooks by a horizontal cutting mechanism and a vertical cutting mechanism. However, the cutting knife has a certain thickness, that is, the front of the knife is a plane, and the back of the knife is an inclined plane. When cutting the notebook, the notebook needs to be pressed first, and then cut. Therefore, due to the thickness of the knife and the inclined plane, the knife will cause extrusion to the notebook, which will cause the cut of the notebook to be deformed, thereby affecting the quality of the notebook. Usually, a margin of about 3mm is left on the side of the notebook that is extruded by the back of the knife, and then the notebook is manually trimmed after cutting. The operation is complicated, and the work efficiency is relatively low. SUMMARY

[0008] The number of first conveying belts is multiple, and the multiple first conveying belts are arranged at intervals along the length direction of the first support beam, and each first cutter is located between two first conveying belts, so that the first cutter does not interfere with the first conveying belt. And the debris generated after the first cutter cuts the strip falls into the first material receiving through slot from between the two first conveying belts, and finally falls onto the first conveying belt.

Since the second conveying belt penetrates through the second cutting support plate, the second conveying belt can convey the collected debris to the outside of the rack for recycling.

[0010] In a further aspect, a book pulling device is further arranged between the first cutting device and the second cutting device, and the book pulling device comprises a book pulling rack, a horizontal driving assembly and a longitudinal driving assembly are arranged on the book pulling rack, the book pulling rack comprises two opposite parallel book pulling support plates, a first cross beam and a second cross beam are arranged between the two book pulling support plates, the two ends of the first cross beam and the second cross beam are respectively connected with the two book pulling support plates, and the second cross beam is located below the first cross beam in the vertical direction, and a feeding channel through which the books conveyed by the first conveying belt passes is formed between the first cross beam and the second cross beam; a fixed upper chuck and a plurality of movable upper chucks are arranged on the first cross beam, the plurality of movable upper chucks are arranged on the two sides of the fixed upper chuck along the length direction of the first cross beam, the fixed upper chuck is fixedly connected with the first cross beam, and the movable upper chucks can slide transversely relative to the first cross beam; a fixed lower chuck and a plurality of movable lower chucks are arranged on the second cross beam, the plurality of movable lower chucks are arranged on the two sides of the fixed lower chuck along the length direction of the second cross beam, the fixed lower chuck is fixedly connected with the second cross beam, and the movable lower chucks can slide transversely relative to the second cross beam; the longitudinal driving assembly acts on the fixed upper chuck and the movable upper chucks; the longitudinal driving assembly acts on the fixed upper chuck to drive the fixed upper chuck to move close to the fixed lower chuck to clamp the books in the middle position of the plurality of books in the feeding channel in cooperation with the fixed lower chuck; the longitudinal driving assembly acts on the movable upper chucks to drive the movable upper chucks to move close to the movable lower chucks to clamp the books other than the book clamped by the fixed upper chuck in cooperation with the movable lower chucks; the horizontal driving assembly is arranged on the book pulling rack, and the horizontal driving assembly is connected with the movable upper chucks and the movable lower chucks to drive the movable upper chucks and the movable lower chucks to move along the width direction of the feeding channel to drive the clamped books and the adjacent books to move away from each other.

[0011] The movable upper clamp is driven by the longitudinal driving assembly to move close to the movable lower clamp to cooperate with the book clamped in the feeding channel by the movable lower clamp. At the same time, the movable upper clamp and the movable lower clamp are driven by the transverse driving assembly to move along the width direction of the feeding channel to drive the clamped book to move away from the adjacent book. By moving the clamped book away from the adjacent book, a space is left between the two adjacent books, so that the book does not flow into the second slitting device, and the second cutter does not interfere with the adjacent book when trimming the to-be-trimmed side edge.

[0012] And since the book in the middle position does not need to move, only the books on both sides need to be moved to avoid interference with the book in the middle position. The book in the middle position is clamped and fixed by the fixed upper clamp and the fixed lower clamp to avoid movement.

[0013] In a further aspect, the rotating shaft extends along the length direction of the first cross beam and is rotatably connected with the two book pulling support plates. The transverse driving assembly includes a first transverse driving swing arm, a first transverse driving vertical rod, a second transverse driving vertical rod, a second transverse driving swing arm, and a third transverse driving swing arm. The tail end of the first transverse driving swing arm is fixedly connected with the rotating shaft. The head end of the first transverse driving swing arm is hingedly connected with the tail end of the first transverse driving vertical rod. The tail end of the second transverse driving vertical rod is hingedly connected with the head end of the first transverse driving vertical rod. The head end and the tail end of the second transverse driving vertical rod are respectively hingedly connected with the head of the second transverse driving swing arm and the tail of the third transverse driving swing arm.

[0014] When the rotating shaft rotates, the rotating shaft drives the first transverse driving swing arm, thereby driving the first transverse driving vertical rod to move up and down. The first transverse driving vertical rod drives the second transverse driving vertical rod to move up and down. Since the head end and the tail end of the second transverse driving vertical rod are respectively hingedly connected with the head of the second transverse driving swing arm and the tail of the third transverse driving swing arm, the second transverse driving swing arm and the third transverse driving swing arm rotate relative to the connected first cross beam or second cross beam. When the second transverse driving swing arm rotates, the movable upper clamp is pulled through the first transverse driving cross rod. When the third transverse driving swing arm rotates, the movable lower clamp is pulled through the second transverse driving cross rod. The purpose of driving the movable upper clamp and the movable lower clamp to move transversely is achieved.

[0015] In a further scheme, the longitudinal driving assembly comprises a first longitudinal driving swing arm, a second longitudinal driving swing arm and a longitudinal driving vertical rod, the first longitudinal driving swing arm is fixedly connected with the rotating shaft, two ends of the longitudinal driving vertical rod are respectively connected with the first longitudinal driving swing arm and the second longitudinal driving swing arm, the second cross beam is provided with a supporting rod along the length direction of the second cross beam, the supporting rod penetrates through the second longitudinal driving swing arm, so that the second longitudinal driving swing arm can rotate around the axis of the supporting rod; the second longitudinal driving swing arm is connected with an abutting piece, the movable upper chuck comprises a base, the base is provided with a sliding piece, the sliding piece can slide relative to the base in the vertical direction; when the rotating shaft drives the first longitudinal driving swing arm to swing upward, the first longitudinal driving swing arm drives the longitudinal driving vertical rod to rise and drives the second longitudinal driving swing arm to rotate upward, so that the abutting piece abuts against the sliding piece and drives the sliding piece to move away from the movable lower chuck; when the rotating shaft drives the first longitudinal driving swing arm to swing downward, the first longitudinal driving swing arm drives the longitudinal driving vertical rod to descend and drives the second longitudinal driving swing arm to rotate downward, so that the abutting piece is separated from the sliding piece, and the sliding piece falls and is combined with the movable lower chuck to clamp the book.

[0016] When the rotating shaft rotates to drive the first longitudinal driving swing arm to swing, the longitudinal driving vertical rod is driven to rise and the second longitudinal driving swing arm is driven to rotate upward, so that the abutting piece abuts against the sliding piece and drives the sliding piece to move away from the movable lower chuck. When the rotating shaft drives the first longitudinal driving swing arm to swing downward, the first longitudinal driving swing arm drives the longitudinal driving vertical rod to descend and drives the second longitudinal driving swing arm to rotate downward, so that the abutting piece is separated from the sliding piece, and the sliding piece falls and is combined with the movable lower chuck to clamp the book. Like the transverse driving assembly, the same rotating shaft is used for driving, so that the book can be pulled while being clamped, the process time is shortened, the work efficiency is improved, two driving members are combined into one, the consumables are reduced, and the structural space is reduced.

[0017] In a further scheme, a pull book driving shaft, a transmission shaft, a transmission connecting rod and a transmission swing arm are further included, the pull book driving shaft and the transmission shaft both extend along the length direction of the rotating shaft and are rotatably connected with the first slitting support plate, one end of the pull book driving shaft is connected with a pull book driving motor, a pull book cam is arranged on the pull book driving shaft, the pull book cam is located below the first conveying belt, the head end of the transmission swing arm is fixedly connected with the transmission shaft, a pull book protrusion is arranged at the tail end of the transmission swing arm, the pull book protrusion abuts against the outer wheel wall of the cam, when the pull book cam rotates, the transmission swing arm and the transmission shaft are driven to rotate around the axis of the transmission shaft through the pull book protrusion, the head end of the transmission connecting rod is hingedly connected with the rotating shaft, the tail end of the transmission connecting rod is hingedly connected with the transmission swing arm, when the transmission swing arm rotates, the rotating shaft is driven to synchronously rotate through the transmission connecting rod; and the transmission swing arm is acted on by a pull book elastic member, when the transmission swing arm and the transmission shaft rotate around the axis of the transmission shaft, the pull book elastic member deforms, and the force of the pull book elastic member forces the pull book protrusion on the transmission swing arm to always abut against the outer wheel wall of the pull book cam.

[0018] By driving the pull book driving shaft to rotate, the outer wall of the pull book cam on the pull book driving shaft abuts against the pull book protrusion on the transmission swing arm, so as to drive the transmission swing arm to rotate, and the purpose of driving the rotating shaft to rotate is achieved. If the motor is directly used to drive the rotating shaft to rotate, in order to realize the reciprocating movement of the upper and lower moving clamps, the motor needs to be switched back and forth between forward rotation and reverse rotation, and if the motor is used to drive the pull book cam to rotate, the motor only needs to be forward rotated all the time, and the reciprocating movement of the upper and lower moving clamps is realized through the shape transformation of the outer wall of the pull book cam.

[0019] In a further scheme, a third conveying belt is further arranged between the two pull book support plates, the third conveying belt includes an upper conveying belt and a lower conveying belt, the upper conveying belt and the lower conveying belt are each connected at the head and tail to form a closed loop, the upper conveying belt and the lower conveying belt are located behind the feeding channel along the conveying direction of the books, a lifting driving assembly is arranged on the rack, the lifting driving assembly is connected with the upper conveying belt and is used to drive the upper conveying belt to move close to or away from the lower conveying belt; when the upper conveying belt moves away from the lower conveying belt, an opening into which the books can be inserted is formed between the upper conveying belt and the lower conveying belt, a space is left between the third conveying belt and the first conveying belt, the upper and lower moving clamps are located between the third conveying belt and the first conveying belt, and the opening is opposite to the feeding channel; when the upper conveying belt moves close to the lower conveying belt, the belt surface of the upper conveying belt clamps the books located at the opening together with the belt surface of the lower conveying belt. By lifting the upper conveying belt through the lifting driving assembly, the opening is formed between the upper conveying belt and the lower conveying belt, so as to facilitate receiving the books after the books are separated.

[0020] In a further aspect, the lifting driving assembly comprises a first lifting driving swing arm, a lifting driving connecting rod, a second lifting driving swing arm and a support shaft, the tail end of the first lifting driving swing arm is fixedly connected with the rotating shaft, the head end of the first lifting driving swing arm is hingedly connected with the tail end of the lifting driving connecting rod, the tail end of the second lifting driving swing arm is hingedly connected with the head end of the lifting driving connecting rod, the two ends of the support shaft are rotatably connected with two pull-in support plates respectively, the head end of the second lifting driving swing arm is fixedly connected with the support shaft, a fixing member extending downward in the vertical direction is arranged on the support shaft, a roller is arranged on the fixing member, the upper conveying belt passes through the roller, when the rotating shaft drives the first lifting driving swing arm to rotate upward, the first lifting driving swing arm drives the lifting driving connecting rod to rise and drives the support shaft to rotate, forcing the fixing member to drive the upper conveying belt to rise and move away from the lower conveying belt.

[0021] The tail end of the first lifting driving swing arm is fixedly connected with the rotating shaft, when the rotating shaft rotates, the first lifting driving swing arm swings, thereby driving the lifting driving connecting rod to make lifting movement, so that the second lifting driving swing arm swings, when the second lifting driving swing arm swings, the support shaft rotates, finally driving the fixing member to rotate around the support shaft. Since the upper conveying belt passes through the roller on the fixing member, when the fixing member rotates around the support shaft, the upper conveying belt makes rising or descending movement.

[0022] In a further scheme, the pull book rack is further provided with a book positioning mechanism, which comprises a first positioning crossbar, a second positioning crossbar and a positioning driving assembly. The pull book rack is further provided with a fixed plate, and a disc is rotatably connected to the fixed plate. The positioning driving assembly is connected with the disc and used to drive the disc to rotate around the center of the disc. The first positioning crossbar and the second positioning crossbar are parallel to each other. The disc has a disc surface which is perpendicular to the central axis of the disc. The disc surface has an upper disc surface above the center of the disc and a lower disc surface below the center of the disc. The head end of the first positioning crossbar is hinged to the upper disc surface, and the head end of the second positioning crossbar is hinged to the lower disc surface. The first positioning crossbar is provided with a first positioning plate, and the second positioning crossbar is provided with a second positioning plate. A space between the first positioning plate and the second positioning plate forms a book inlet channel. The book inlet channel can flow into the book separated by the moving upper clamp and the moving lower clamp. A space between the third conveying belt and the second conveying belt is left, and the first positioning plate and the second positioning plate are located between the third conveying belt and the second conveying belt. The space between the third conveying belt and the second conveying belt is smaller than the length of the book. When the positioning driving assembly drives the disc to rotate, the disc drives the first positioning crossbar and the second positioning crossbar to move along the length direction of the first positioning crossbar and the second positioning crossbar. The moving direction of the first positioning crossbar is opposite to that of the second positioning crossbar, so as to force the first positioning plate and the second positioning plate to move close to each other to push and clamp the book in the book inlet channel, or to move away from each other. When the first positioning plate and the second positioning plate move close to each other to push and clamp the book in the book inlet channel, the side edge to be cut of the pushed book is aligned with the second cutter.

[0023] Since the disc has a disc surface which is perpendicular to the central axis of the disc, the disc surface has an upper disc surface above the center of the disc and a lower disc surface below the center of the disc, the head end of the first positioning crossbar is hinged to the upper disc surface, and the head end of the second positioning crossbar is hinged to the lower disc surface. By driving the disc to rotate, the first positioning crossbar and the second positioning crossbar will move along the length direction of the first positioning crossbar and the second positioning crossbar and the moving direction is opposite. Since the moving direction of the first positioning crossbar is opposite to that of the second positioning crossbar, the first positioning plate on the first positioning crossbar and the second positioning plate on the second positioning crossbar will move close to or away from each other. When the first positioning plate and the second positioning plate move close to each other, the book in the book inlet channel will be pushed and clamped, so that the side edge to be cut of the book is aligned with the second cutter, avoiding the problem that the second cutter and the side edge to be cut are dislocated to cause the book cannot be cut or the book is cut inside.

[0024] In a further scheme, the positioning driving assembly comprises a positioning driving shaft and a positioning lifting rod, one end of the positioning driving shaft is connected with a positioning driving motor, a positioning cam is arranged on the positioning driving shaft, a fixing rod is further arranged on the positioning rack, a positioning swing arm is connected with the fixing rod, the head end of the positioning swing arm is hinged with the fixing rod, a positioning protrusion is arranged at the tail end of the positioning swing arm, the positioning protrusion is in abutment with the outer wall of the positioning cam, and the head end of the positioning lifting rod is hinged with the disc, and the tail end of the positioning lifting rod is hinged with the positioning swing arm; when the positioning cam rotates, the positioning protrusion drives the positioning swing arm to rotate around the fixing rod, forcing the positioning lifting rod to ascend and descend along the length direction of the positioning lifting rod, so that the disc rotates around the center of the disc; and the positioning swing arm is acted on by a positioning elastic member, when the positioning protrusion drives the positioning swing arm to rotate around the fixing rod, the positioning elastic member deforms, and the restoring force of the positioning elastic member forces the positioning protrusion on the positioning swing arm to always abut against the outer wall of the positioning cam.

[0025] Compared with the prior art, the book strip is cut into multiple books by the first cutter, but since the cutter has a cutting surface and a cutting back, the cutting back has a certain thickness, so that the side edge of the book opposite to the cutting back has a certain allowance to form a to-be-trimmed side edge, at this time, the to-be-trimmed side edge is trimmed by the second cutter, since the cutting back of the second cutter faces in the opposite direction to the cutting back of the first internal cutter, the to-be-trimmed side edge can be accurately trimmed, and the automatic cutting of the book strip is realized through secondary cutting.

[0026] And since the first cutter comprises two first external cutters adjacent to the left and right side walls of the conveying belt and multiple first internal cutters located between the two first external cutters, the cutting back of the two first external cutters is arranged to face away from the middle part of the conveying belt, and the cutting back of the two first internal cutters adjacent to the first external cutters faces in the opposite direction to the cutting back of the adjacent first external cutter. So that the two books adjacent to the two sides of the first conveying belt can be directly cut, and when secondary cutting, the positions of the two books adjacent to the two sides of the first conveying belt do not need to be considered, and the two books adjacent to the two sides of the first conveying belt do not need to be positioned.

A plurality of first cutters 8 for cutting the book block 4 are arranged on the first support beam 6 along the length direction of the first support beam 6.

[0048] It is easy to understand that the cutter has a blade back and a blade face, and in the present scheme, the side edge of the book block 4 opposite to the blade back of the first cutter 8 is the side edge to be trimmed, and the side edge to be trimmed leaves a certain margin compared to the expected width of the book block 4.

[0049] In the present scheme, as shown in Figure 4 , the first cutter 8 includes two first external cutters 9 adjacent to the left and right side walls of the conveying belt and a plurality of first internal cutters 10 located between the two first external cutters 9, and the blade back of the first external cutter 9 is arranged in a direction away from the middle of the conveying belt. The outer side edges of the book blocks 4 at both ends of the book block are cut by the two first external cutters 9, and since the blade back of the first external cutter 9 is arranged in a direction away from the middle of the conveying belt, the outer side edges of the book blocks 4 at both ends of the book block do not need to be processed in subsequent cutting.

[0050] And as a more preferred embodiment, the blade back of the two first internal cutters 10 adjacent to the first external cutter 9 is arranged in a direction opposite to the blade back of the adjacent first external cutter 9. So that the two book blocks 4 adjacent to the two sides of the first conveying belt 7 can be directly cut, and the positions of the two book blocks 4 adjacent to the two sides of the first conveying belt 7 do not need to be considered when the second slitting device 2 performs secondary slitting on the book block 4.

[0051] In the present scheme, the number of first conveying belts 7 is multiple, and the multiple first conveying belts 7 are arranged at intervals along the length direction of the first support beam 6, and each first cutter 8 is located between two first conveying belts 7. A first support table 11 and a first conveying belt 13 are further arranged between the two first slitting support plates 5, the first support table 11 is located below the first conveying belt 7, and the first support table 11 is provided with a first material receiving slot 12, which is located directly below the first cutter 8 and extends along the length direction of the first support beam 6. The first material receiving slot 12 penetrates the upper and lower end faces of the first support table 11, the first conveying belt 13 is located below the first support table 11, and the first conveying belt 13 extends along the length direction of the first material receiving slot 12 and penetrates one of the first slitting support plates 5, and the belt surface of the first conveying belt 13 is opposite to the slot of the material receiving slot.

[0052] The number of first conveying belts 7 is multiple, and the multiple first conveying belts 7 are arranged at intervals along the length direction of the first support beam 6, and each first cutter 8 is located between two first conveying belts 7, so that the first cutter 8 does not interfere with the first conveying belt 7. And the first cutter 8 cuts the barb produced after cutting, which falls into the first material receiving slot 12 from the middle of the two first conveying belts 7, and finally falls onto the first conveying belt 13. Since the first conveying belt 13 penetrates the first slitting support plate 5, the first conveying belt 13 can convey the collected debris to the outside of the rack for recycling.

[0053] Please refer to Figures 5-11 , the pull bar separation device 3 includes a pull bar rack, and the pull bar rack is provided with a transverse driving assembly and a longitudinal driving assembly. The pull bar rack includes two opposite parallel pull bar support plates 14, and a first cross beam 15 and a second cross beam 16 are arranged between the two pull bar support plates 14. The two ends of the first cross beam 15 and the second cross beam 16 are respectively connected with the two pull bar support plates 14, and the second cross beam 16 is located below the first cross beam 15 in the vertical direction, and a feeding channel 17 through which the barb 4 conveyed by the first conveying belt passes is formed between the first cross beam 15 and the second cross beam 16.

[0054] As Figure 8As shown, a plurality of moving upper clamping heads 18 are slidably arranged on the first cross beam 15, and a plurality of moving lower clamping heads 19 are slidably arranged on the second cross beam 16. Specifically, the first cross beam 15 is provided with a first sliding support rod 22 extending along the length direction of the first cross beam 15, and the first sliding support rod 22 penetrates the plurality of moving upper clamping heads 18 in sequence. The second cross beam 16 is provided with a second sliding support rod 23 extending along the length direction of the second cross beam 16, and the second sliding support rod 23 penetrates the plurality of moving lower clamping heads 19 in sequence. The longitudinal driving assembly acts on the moving upper clamping heads 18, for driving the moving upper clamping heads 18 to move close to the moving lower clamping heads 19 to cooperate with the moving lower clamping heads 19 to clamp the book 4 in the feeding channel 17, or to drive the moving upper clamping heads 18 to move away from the moving lower clamping heads 19 to release the clamped book 4. The transverse driving assembly is arranged on the book pulling machine frame, and is connected with the moving upper clamping heads 18 and the moving lower clamping heads 19 respectively, for driving the moving upper clamping heads 18 and the moving lower clamping heads 19 to move along the width direction of the feeding channel 17 to drive the clamped book 4 to move away from the adjacent book 4.

[0055] The first cross beam 15 is further provided with a fixed upper clamping head 20, and the second cross beam 16 is further provided with a fixed lower clamping head 21. The plurality of moving upper clamping heads 18 are arranged on the two sides of the fixed upper clamping head 20 along the length direction of the first cross beam 15, and the plurality of moving lower clamping heads 19 are arranged on the two sides of the fixed lower clamping head 21 along the length direction of the second cross beam 16. The longitudinal driving assembly acts on the fixed upper clamping head 20, for driving the fixed upper clamping head 20 to move close to the fixed lower clamping head 21 to cooperate with the fixed lower clamping head 21 to clamp the book 4 in the feeding channel 17 at the intermediate position of the plurality of books 4, or to drive the fixed upper clamping head 20 to move away from the fixed lower clamping head 21 to release the clamped book 4.

[0056] The book 4 at the intermediate position does not need to move, and only the books 4 on the two sides need to be moved to avoid interference with the book 4 at the intermediate position. The fixed upper clamping head 20 and the fixed lower clamping head 21 clamp and fix the book 4 at the intermediate position to avoid movement of the book 4 at the intermediate position.

[0057] As a specific embodiment, the book pulling and separating device 3 further comprises a rotating shaft 24 extending along the length direction of the first cross beam 15 and rotatably connected with the two book pulling support plates 14. Please refer to Figure 10 and Figure 11The longitudinal driving assembly comprises a first longitudinal driving swing arm 25, a second longitudinal driving swing arm 26 and a longitudinal driving vertical rod 27. The first longitudinal driving swing arm 25 is fixedly connected with the rotating shaft 24, and the longitudinal driving vertical rod 27 is connected with the first longitudinal driving swing arm 25 and the second longitudinal driving swing arm 26 at two ends thereof. The second cross beam 16 is provided with a support rod 28 extending along the length direction thereof, the support rod 28 penetrating through the second longitudinal driving swing arm 26, so that the second longitudinal driving swing arm 26 can rotate around the axis of the support rod 28. Meanwhile, the second longitudinal driving swing arm 26 is connected with an abutting piece 29, and the moving upper chuck 18 comprises a base 30 provided with a sliding piece slidable relative to the base 30 in the vertical direction. When the rotating shaft 24 rotates around the axis thereof, the first longitudinal driving swing arm 25 is swung upward, the first longitudinal driving swing arm 25 drives the longitudinal driving vertical rod 27 to rise and drives the second longitudinal driving swing arm 26 to rotate upward. In the process of the second longitudinal driving swing arm 26 rotating upward, the abutting piece 29 abuts against the sliding piece on the base 30 and drives the sliding piece to move away from the moving lower chuck 19. When the rotating shaft 24 drives the first longitudinal driving swing arm 25 to swing downward, the first longitudinal driving swing arm 25 drives the longitudinal driving vertical rod 27 to descend and drives the second longitudinal driving swing arm 26 to rotate downward, so that the abutting piece 29 is separated from the sliding piece, the sliding piece falls and abuts against the moving lower chuck 19 to clamp the book 4.

[0058] Specifically, as Figure 11As shown, the base 30 is provided with a sliding channel 31 penetrating the upper and lower end faces of the base 30 in the vertical direction, and the end face of the base 30 facing the support rod 28 is provided with a through slot in the vertical direction, which communicates with the sliding channel 31. The sliding member comprises a sliding rod 32 and a spring 33, the sliding rod 32 is vertically inserted into the sliding channel 31, and the bottom end of the sliding rod 32 is exposed to the lower end face of the base 30. Meanwhile, the bottom end of the sliding rod 32 is provided with a limiting member 35 extending in the radial direction of the sliding rod 32, the spring 33 is sleeved on the sliding rod 32, and the two ends of the spring 33 abut against the limiting member 35 and the lower end face of the base 30 respectively. In addition, the head end of the sliding rod 32 is also provided with a fixed block 34 extending in the radial direction of the sliding rod 32 and exposed to the slot opening of the through slot. When the rotating shaft 24 drives the first longitudinal driving swing arm 25 to swing upward, the abutting member 29 abuts against the fixed block 34 and drives the sliding rod 32 to rise, and the sliding rod 32 drives the limiting member 35 to rise and forces the spring 33 to compress in the process of rising. When the rotating shaft 24 drives the first longitudinal driving swing arm 25 to swing downward, the sliding rod 32 drives the limiting member 35 to descend, and after the spring 33 loses the limiting of the limiting member 35, the restoring force of the spring 33 cooperates with the gravity of the sliding rod 32 to drive the sliding rod 32 to fall and abut against the moving lower clamp 19 to clamp the book 4. The sliding rod 32 is driven by the spring 33 to fall and abut against the moving lower clamp 19 to clamp the book 4, and after clamping, the limiting member 35 cannot easily move away from the moving lower clamp 19 due to the elastic force of the spring 33, avoiding the separation of the sliding rod 32 and the moving lower clamp 19 during the movement of the book 4, which causes the book 4 to lose the clamping force of the upper and lower end faces and cannot move transversely.

[0059] As Figure 8As shown, the transverse driving assembly includes a first transverse driving swing arm 36, a first transverse driving vertical rod 37, a second transverse driving vertical rod 38, a second transverse driving swing arm 39 and a third transverse driving swing arm 40. The tail end of the first transverse driving swing arm 36 is fixedly connected with the rotating shaft 24, the head end of the first transverse driving swing arm 36 is hingedly connected with the tail end of the first transverse driving vertical rod 37, and the tail end of the second transverse driving vertical rod 38 is hingedly connected with the head end of the first transverse driving vertical rod 37. When the rotating shaft 24 rotates, the first transverse driving swing arm 36 swings, the first transverse driving swing arm 36 drives the first transverse driving vertical rod 37 to make lifting action in the vertical direction, thereby driving the second transverse driving vertical rod 38 to make lifting action in the vertical direction. The head end and the tail end of the second transverse driving vertical rod 38 are respectively hingedly connected with the head of the second transverse driving swing arm 39 and the tail of the third transverse driving swing arm 40. The middle part of the second transverse driving swing arm 39 is hingedly connected with the first cross beam 15, the middle part of the third transverse driving swing arm 40 is hingedly connected with the second cross beam 16, the tail of the second transverse driving swing arm 39 is connected with the moving upper chuck 18 through a first transverse driving cross rod 41, and the head of the third transverse driving swing arm 40 is connected with the moving lower chuck 19 through a second transverse driving cross rod 42. When the second transverse driving vertical rod 38 makes lifting action in the vertical direction, the second transverse driving swing arm 39 and the third transverse driving swing arm 40 will be driven to rotate, thereby pulling the moving upper chuck 18 to move horizontally through the first transverse driving cross rod 41 and pulling the moving lower chuck 19 to move horizontally through the second transverse driving cross rod 42.

[0060] When the rotating shaft 24 rotates to drive the first horizontal driving swing arm 36 to rotate downward, the first horizontal driving swing arm 36 drives the first horizontal driving vertical rod 37 to descend, and the first horizontal driving vertical rod 37 drives the second horizontal driving vertical rod 38 to descend. The head end of the second horizontal driving vertical rod 38 pulls the head end of the second horizontal driving swing arm 39 to descend, so that the second horizontal driving swing arm 39 rotates around the middle part of the hinge joint with the first horizontal beam 15, and the tail end of the second horizontal driving swing arm 39 rotates upward and moves away from the middle position of the first horizontal beam 15, thereby pulling the moving upper clamp head 18 to move away from the middle position of the first horizontal beam 15 through the first horizontal driving vertical rod 37. At the same time, the tail end of the second horizontal driving vertical rod 38 pulls the tail end of the third horizontal driving swing arm 40 to descend, so that the third horizontal driving swing arm 40 rotates around the middle part of the hinge joint with the second horizontal beam 16, and the head end of the third horizontal driving swing arm 40 moves away from the middle position of the second horizontal beam 16, thereby pulling the moving lower clamp head 19 to move away from the middle position of the second horizontal beam 16 through the second horizontal driving vertical rod 38. The simultaneous horizontal movement of the moving upper clamp head 18 and the moving lower clamp head 19 pulls the clamped book 4 and the adjacent book 4 to move away from each other. When the rotating shaft 24 rotates to drive the first horizontal driving swing arm 36 to rotate upward, the rotating direction and the moving direction of the first horizontal driving swing arm 36, the first horizontal driving vertical rod 37, the second horizontal driving vertical rod 38, the second horizontal driving swing arm 39 and the third horizontal driving swing arm 40 are opposite to those described above, so that the moving upper clamp head 18 and the moving lower clamp head 19 move toward the middle position of the second horizontal beam 16 to achieve reset.

[0061] It should be noted that in the present scheme, the number of the moving upper clamp head 18 and the moving lower clamp head 19 is multiple, each moving upper clamp head 18 is connected with the first horizontal driving horizontal rod 41 and the second horizontal driving swing arm 39, and each moving lower clamp head 19 is connected with the second horizontal driving horizontal rod 42 and the third horizontal driving swing arm 40. Although each book 4 is clamped by the moving upper clamp head 18 and the moving lower clamp head 19 and is horizontally moved by the first horizontal driving vertical rod 37 and the second horizontal driving vertical rod 38, the length of the first horizontal driving horizontal rod 41 and the second horizontal driving horizontal rod 42 connected with each moving upper clamp head 18 and each moving lower clamp head 19 is different due to the different positions of each moving upper clamp head 18 and each moving lower clamp head 19. Taking the moving upper clamp head 18 as an example, when the second horizontal driving swing arm 39 and the third horizontal driving swing arm 40 rotate by the same angle, although the angles of rotation of the first horizontal driving horizontal rods 41 with different lengths are the same, the horizontal moving distances of the moving upper clamp heads 18 are different due to the different lengths of the first horizontal driving horizontal rods 41, and the distance between the adjacent two books 4 is still gradually expanded.

[0062] It is also necessary to point out that, since the first lateral driving swing arm 36 in the lateral driving assembly and the first longitudinal driving swing arm 25 in the longitudinal driving assembly are both connected with the rotating shaft 24, when the rotating shaft 24 rotates, the lateral driving assembly and the longitudinal driving assembly can be simultaneously driven to operate, and when the rotating shaft 24 rotates to drive the first lateral driving swing arm 36 to rotate downward, the first longitudinal driving swing arm 25 is also simultaneously driven to rotate downward. As described above, when the first longitudinal driving swing arm 25 rotates downward, the spring 33 loses the limitation of the limiting piece 35, and the restoring force of the spring 33 cooperates with the gravity of the sliding rod 32 to drive the sliding rod 32 to fall and move to be attached to the moving lower clamp 19 to clamp the book 4. At the same time, when the first lateral driving swing arm 36 rotates downward, the moving upper clamp 18 and the moving lower clamp 19 are simultaneously moved to pull the clamped book 4 and the adjacent book 4 away. Thus, the synchronous action of clamping the book 4 by the moving upper clamp 18 and the moving lower clamp 19 and pulling the clamped book 4 and the adjacent book 4 away by the moving upper clamp 18 and the moving lower clamp 19 is realized. The process time is shortened, the work efficiency is improved, and two driving members are combined into one, which reduces the consumption of materials and the structural space.

[0063] As a more preferred embodiment, a plurality of first hinge points 43 are arranged between the tail and the middle of the second lateral driving swing arm 39, a plurality of second hinge points 44 are arranged in the vertical direction on the moving upper clamp 18, the head end of the first lateral driving cross rod 41 can be connected with any first hinge point 43, and the tail end of the first lateral driving cross rod 41 can be connected with any second hinge point 44. Similarly, a plurality of third hinge points 45 are arranged between the head and the middle of the third lateral driving swing arm 40, a plurality of fourth hinge points 46 are arranged in the vertical direction on the moving lower clamp 19, the head end of the second lateral driving cross rod 42 can be connected with any third hinge point 45, and the tail end of the second lateral driving cross rod 42 can be connected with any fourth hinge point 46. When the required interval between the adjacent books 4 is different, by connecting the head and tail ends of the first lateral driving cross rod 41 with different first hinge points 43 and second hinge points 44, the distance moved by the moving upper clamp 18 under the same angle of rotation of the second lateral driving swing arm 39 is changed. Similarly, by connecting the head and tail ends of the second lateral driving cross rod 42 with different third hinge points 45 and fourth hinge points 46, the distance moved by the moving lower clamp 19 under the same angle of rotation of the third lateral driving swing arm 40 is changed.

[0064] Meanwhile, the transverse driving assembly further comprises a locking member 47, the first transverse driving cross rod 41 and the second transverse driving cross rod 42 each comprise a first connecting rod 48 and a second connecting rod 49, the first connecting rod 48 and the second connecting rod 49 each extend in the same direction, the tail end of the first connecting rod 48 is connected with the second transverse driving swing arm 39 or the third transverse driving swing arm 40, and the head end of the second connecting rod 49 is connected with the movable upper chuck 18 or the movable lower chuck 19. The head end of the first connecting rod 48 and the tail end of the second connecting rod 49 each penetrate the locking member 47, the locking member 47 is provided with a through hole, and the first connecting rod 48 and the second connecting rod 49 are each provided with a threaded hole at intervals along the length direction of the first connecting rod 48 and the second connecting rod 49. When the first connecting rod 48 and the second connecting rod 49 move to a specified position through the locking member 47, a bolt is inserted into the threaded hole, and the bolt is threadedly connected with the threaded hole on the first connecting rod 48 and the second connecting rod 49. The length of the first transverse driving cross rod 41 and the second transverse driving cross rod 42 is changed by stretching the first connecting rod 48 and the second connecting rod 49, so as to be matched with different hinge points. The position of the movable upper chuck 18 and the movable lower chuck 19 is different due to the different clamping positions of the book 4 of different widths, and the length of the first transverse driving cross rod 41 and the second transverse driving cross rod 42 can also be adjusted to be matched with the book 4 of different widths.

[0065] In the present scheme, in order to drive the rotation of the rotation shaft 24, the book pulling and separating device 3 further comprises a book pulling driving shaft 50, a transmission shaft 51, a transmission connecting rod 52 and a transmission swing arm 53. The book pulling driving shaft 50 and the transmission shaft 51 each extend along the length direction of the rotation shaft 24, but the book pulling driving shaft 50 and the transmission shaft 51 in the present scheme are rotatably connected with the first cutting support plate 5. One end of the book pulling driving shaft 50 is connected with a book pulling driving motor, and the book pulling driving shaft 50 is provided with a book pulling cam 54 which is located below the first conveying belt 13. Through the rotatable connection of the book pulling driving shaft 50 and the transmission shaft 51 with the first cutting support plate 5 in the present scheme, and the location of the book pulling cam 54 below the first conveying belt 13 improves the space utilization rate and avoids the occurrence of a large gap between the first cutting device 1 and the book pulling and separating device 3.

[0066] The head end of the transmission swing arm 53 is fixedly connected with the transmission shaft 51, and the tail end of the transmission swing arm 53 is provided with a book pulling protrusion 55 which abuts against the outer wheel wall of the book pulling cam 54. When the book pulling cam 54 rotates, the transmission swing arm 53 and the transmission shaft 51 are driven to rotate around the axis of the transmission shaft 51 through the book pulling protrusion 55. The head end of the transmission connecting rod 52 is hingedly connected with the rotation shaft 24, and the tail end of the transmission connecting rod 52 is hingedly connected with the transmission swing arm 53. When the transmission swing arm 53 rotates, the rotation shaft 24 is synchronously driven to rotate through the transmission connecting rod 52.

[0067] And the transmission swing arm 53 is acted on by a tension spring 56, when the transmission swing arm 53 and the transmission shaft 51 rotate around the axis of the transmission shaft 51, the tension spring 56 deforms, the force of the tension spring 56 forces the tension protrusion 55 on the transmission swing arm 53 to always abut against the outer wall of the tension cam 54. Specifically, as shown in Figure 5 The tension spring 56 in the scheme is a tension spring, one end of the tension spring is connected with the transmission swing arm 53, and the first cutting support plate 5 is fixedly provided with a connecting plate 65, and the other end of the tension spring is connected with the connecting plate 65.

[0068] By driving the tension drive shaft 50 to rotate, the outer wall of the tension cam 54 on the tension drive shaft 50 abuts against the tension protrusion 55 on the transmission swing arm 53, thereby driving the transmission swing arm 53 to rotate, so as to achieve the purpose of driving the rotating shaft 24 to rotate. If the motor is directly used to drive the rotating shaft 24 to rotate, in order to realize the reciprocating movement of the upper movable clamp 18 and the lower movable clamp 19, the motor needs to be switched back and forth between forward rotation and reverse rotation, and the motor only needs to be forward rotated all the time when the motor is used to drive the tension cam 54 to rotate, and the reciprocating movement of the upper movable clamp 18 and the lower movable clamp 19 is realized through the shape change of the outer wall of the tension cam 54.

[0069] The third conveying belt 57 is further arranged between the two tension support plates 14, the third conveying belt 57 includes an upper conveying belt 58 and a lower conveying belt 59, and the upper conveying belt 58 and the lower conveying belt 59 are each connected head to tail to form a closed loop. In this embodiment, the upper conveying belt 58 and the lower conveying belt 59 are located behind the feeding channel 17 along the conveying direction of the book 4, and a lifting driving assembly is arranged on the tension machine frame, the lifting driving assembly is connected with the upper conveying belt 58 and is used to drive the upper conveying belt 58 to move close to or away from the lower conveying belt 59. When the upper conveying belt 58 moves away from the lower conveying belt 59, an opening is formed between the upper conveying belt 58 and the lower conveying belt 59, and the book 4 can be inserted into the opening. The third conveying belt 57 and the first conveying belt 7 are spaced apart, the upper movable clamp 18 and the lower movable clamp 19 are located between the third conveying belt 57 and the first conveying belt 7, and the opening is opposite to the feeding channel 17. When the upper conveying belt 58 moves close to the lower conveying belt 59, the belt surface of the upper conveying belt 58 cooperates with the belt surface of the lower conveying belt 59 to clamp the book 4 located in the opening.

[0070] The upper conveying belt 58 is lifted by the lifting driving assembly to form an opening between the upper conveying belt 58 and the lower conveying belt 59 to facilitate receiving the book block 4 after the book block 4 is separated. The book block 4 after the book block 4 is output from the first conveying belt 7 and moved to the interval between the third conveying belt 57 and the first conveying belt 7, and is clamped by the moving upper clamp 18 and the moving lower clamp 19. After the book block 4 is clamped by the moving upper clamp 18 and the moving lower clamp 19, the book block 4 falls into the opening between the upper conveying belt 58 and the lower conveying belt 59. When the upper conveying belt 58 moves towards the lower conveying belt 59, the surface of the upper conveying belt 58 clamps the book block 4 in the opening together with the surface of the lower conveying belt 59, and the book block 4 is continuously conveyed.

[0071] As a specific embodiment, the lifting driving assembly comprises a first lifting driving swing arm 60, a lifting driving connecting rod 61, a second lifting driving swing arm 62 and a supporting shaft 63. The tail end of the first lifting driving swing arm 60 is fixedly connected with the rotating shaft 24, the head end of the first lifting driving swing arm 60 is hingedly connected with the tail end of the lifting driving connecting rod 61, and the tail end of the second lifting driving swing arm 62 is hingedly connected with the head end of the lifting driving connecting rod 61. The two ends of the supporting shaft 63 are rotatably connected with the two book block supporting plates 14 respectively, and the head end of the second lifting driving swing arm 62 is fixedly connected with the supporting shaft 63. The supporting shaft 63 is provided with a fixed part 64 extending downward in the vertical direction, the fixed part 64 is provided with a roller, and the upper conveying belt 58 passes through the roller on the fixed part 64. When the rotating shaft 24 drives the first lifting driving swing arm 60 to rotate upward, the first lifting driving swing arm 60 drives the lifting driving connecting rod 61 to rise, and drives the supporting shaft 63 to rotate to force the fixed part 64 to drive the upper conveying belt 58 to rise and move away from the lower conveying belt 59. In this embodiment, the fixed part 64 is a V-shaped mechanism composed of multiple components, but it is also feasible that the fixed part 64 directly extends downward at an angle.

[0072] The book block positioning mechanism is arranged on the book block separating machine frame and located between the first cross beam 15 and the second cutting device 2. Please refer to Figure 12 and Figure 13The positioning mechanism comprises a first positioning cross rod 66, a second positioning cross rod 67 and a positioning driving assembly. Meanwhile, the rack of the book pulling machine is provided with a fixed plate 68, the fixed plate 68 is rotatably connected with a disc 69, the positioning driving assembly is connected with the disc 69 and is used for driving the disc 69 to rotate around the center of the disc 69. The first positioning cross rod 66 and the second positioning cross rod 67 are parallel to each other, the disc 69 has a disc surface which is perpendicular to the central axis of the disc 69, the disc surface has an upper disc surface which is above the center of the disc 69 and a lower disc surface which is below the center of the disc 69, the head end of the first positioning cross rod 66 is hingedly connected with the upper disc surface, and the head end of the second positioning cross rod 67 is hingedly connected with the lower disc surface. In the scheme, the number of the fixed plates 68 is two, the two fixed plates 68 are opposite to each other, and the two fixed plates 68 are both provided with the disc 69, the head end and the tail end of the first positioning cross rod 66 are respectively hingedly connected with the upper disc surfaces of the two discs 69, and the head end and the tail end of the second positioning cross rod 67 are respectively hingedly connected with the lower disc surfaces of the two discs 69.

[0073] Meanwhile, the first positioning cross rod 66 is provided with a first positioning plate 70, the second positioning cross rod 67 is provided with a second positioning plate 71, and the first positioning plate 70 and the second positioning plate 71 are spaced apart to form a book entering channel, and the separated books 4 on the third conveying belt 57 flow into the book entering channel. When the positioning driving assembly drives the disc 69 to rotate, the disc 69 drives the first positioning cross rod 66 and the second positioning cross rod 67 to move along the length direction of the first positioning cross rod 66 and the second positioning cross rod 67, and the moving directions of the first positioning cross rod 66 and the second positioning cross rod 67 are opposite, so as to force the first positioning plate 70 and the second positioning plate 71 to move close to each other to push and clamp the books 4 in the book entering channel, or to force the first positioning plate 70 and the second positioning plate 71 to move away from each other. Preferably, the number of the first positioning plates 70 and the second positioning plates 71 is multiple, the first positioning plates 70 are arranged along the length direction of the first positioning cross rod 66, and the second positioning plates 71 are arranged along the length direction of the second positioning cross rod 67. The first positioning plates 70 and the second positioning plates 71 are one-to-one corresponding, and each first positioning plate 70 and the corresponding second positioning plate 71 form a book entering channel.

[0074] When the positioning driving assembly drives the disc 69 to rotate, the disc 69 drives the first positioning crossbar 66 and the second positioning crossbar 67 to move along the length direction of the first positioning crossbar 66 and the second positioning crossbar 67. Since the head end of the first positioning crossbar 66 is hinged to the top of the disc 69 and the head end of the second positioning crossbar 67 is hinged to the bottom of the disc 69, the moving direction of the first positioning crossbar 66 is opposite to that of the second positioning crossbar 67. Since the first positioning plate 70 is arranged on the first positioning crossbar 66 and the second positioning plate 71 is arranged on the second positioning crossbar 67, when the first positioning crossbar 66 and the second positioning crossbar 67 move, the first positioning plate 70 and the second positioning plate 71 are close to clamp the book 4. In the process of clamping the book 4, the book 4 moves. When the first positioning plate 70 and the second positioning plate 71 clamp the book 4, the positioning of the book 4 is completed.

[0075] Specifically, the positioning driving assembly includes a positioning driving shaft 72 and a positioning lifting rod 73. One end of the positioning driving shaft 72 is connected with a positioning driving motor, and the positioning driving shaft 72 is provided with a positioning cam 74. Meanwhile, the positioning rack (i.e. the book pulling rack) is further provided with a fixed rod 75, the fixed rod 75 is connected with a positioning swing arm 76, the head end of the positioning swing arm 76 is hinged to the fixed rod 75, and the tail end of the positioning swing arm 76 is provided with a positioning protrusion 77, which is in abutment with the outer wall of the positioning cam 74. The head end of the positioning lifting rod 73 is hinged to the disc 69, and the tail end of the positioning lifting rod 73 is hinged to the positioning swing arm 76. When the positioning cam 74 rotates, the positioning protrusion 77 drives the positioning swing arm 76 to rotate around the fixed rod 75, forcing the positioning lifting rod 73 to lift along the length direction of the positioning lifting rod 73, so that the disc 69 rotates around the center of the disc 69. The positioning swing arm 76 is provided with a positioning elastic member. When the positioning protrusion 77 drives the positioning swing arm 76 to rotate around the fixed rod 75, the positioning elastic member deforms. The restoring force of the positioning elastic member forces the positioning protrusion 77 on the positioning swing arm 76 to always abut against the outer wall of the positioning cam 74. Like the book pulling elastic member 56, the positioning elastic member in this scheme is also a tension spring.

[0076] In order to adapt to books 4 of different widths, the book positioning mechanism further includes a first locking member and a second locking member. The head end of the first positioning plate 70 is provided with a first moving seat 85, which is slidably arranged on the first positioning crossbar 66. When the first moving seat 85 moves to a specified position along the length direction of the first positioning crossbar 66, the first locking member acts on the first moving seat 85 to force the first moving seat 85 to be relatively fixed with the first positioning crossbar 66. The head end of the second positioning plate 71 is provided with a second moving seat 86, which is slidably arranged on the second positioning crossbar 67. When the second moving seat 86 moves to a specified position along the length direction of the second positioning crossbar 67, the second locking member acts on the second moving seat 86 to force the second moving seat 86 to be relatively fixed with the second positioning crossbar 67.

[0077] Specifically, the first locking member includes a first positioning screw, the first moving seat 85 is provided with a first rod hole, the first positioning crossbar 66 penetrates the first rod hole, and a first slot is further arranged between the first rod hole and the bottom end surface of the first moving seat 85.

When the first moving seat 85 moves to a specified position, the first nut is twisted to drive the first mounting ear and the second mounting ear to move close to each other, so that the inner wall of the first rod hole is tightly attached to the outer wall of the first positioning crossbar 66, and the first moving seat 85 and the first positioning crossbar 66 are kept relatively fixed.

[0078] The second locking member includes a second positioning screw, the second moving seat 86 is provided with a second rod hole, the second positioning crossbar 67 penetrates the second rod hole, and a second slot is further arranged between the second rod hole and the bottom end surface of the second moving seat 86.

[0079] Please refer to Figures 14-16 , the second cutting device 2 includes a second conveying belt 78, wherein a gap is left between the third conveying belt 57 and the second conveying belt 78, the first positioning plate 70 and the second positioning plate 71 in the above positioning mechanism are located between the third conveying belt 57 and the second conveying belt 78, and the gap between the third conveying belt 57 and the second conveying belt 78 is smaller than the length of the book 4. Since the gap between the third conveying belt 57 and the second conveying belt 78 is smaller than the length of the book 4, the book 4 can enter the second conveying belt 78 before the book 4 completely leaves the third conveying belt 57, so that the book 4 can be smoothly fed. The reason why the second conveying belt 78 does not need to form an opening by lifting the upper conveying belt 58 and separating the lower conveying belt 59 to receive the book 4 is that the book 4 moves a long distance during the pulling process, and if the upper conveying belt 58 is not separated from the lower conveying belt 59 to form an opening, the book 4 will be difficult to move. During the positioning process, the book 4 moves a small distance and does not need to move a large range, so the second conveying belt 78 does not need to form an opening by lifting the upper conveying belt 58 and separating the lower conveying belt 59.

[0080] The second slitting device 2 further comprises a second slitting frame, a second support beam 79 fixedly connected with the second slitting frame, and extending along the width direction of the second conveying belt 78 and located above the second conveying belt 78, and a plurality of second cutters 81 for trimming the to-be-trimmed side edge of the book 4 are arranged on the second support beam 79 along the length direction of the second support beam 79. The number of the second cutters 81 is the same as that of the first internal cutters 10 and corresponds one by one, and the orientation of the back of the second cutter 81 is opposite to that of the corresponding first internal cutter 10. Since the orientation of the back of the second cutter 81 is opposite to that of the corresponding first internal cutter 10, the cutting surface of the second cutter 81 will be opposite to the to-be-trimmed side edge of the book 4, and the trimming of the to-be-trimmed side edge of the book 4 by the second cutter 81 can complete the cutting of the book 4, thereby realizing the automatic slitting of the book 4.

[0081] In the present scheme, the number of the second conveying belts 78 is multiple, and the multiple second conveying belts 78 are arranged at intervals along the length direction of the second support beam 79, and each second cutter 81 is located between two second conveying belts 78. The second slitting frame comprises two second slitting support plates 80 parallel to each other, the two ends of the second support beam 79 are connected with the two second slitting support plates 80 respectively, and a second support table 82 and a second conveying belt 84 are further arranged between the two second slitting support plates 80, the second support table 82 is located below the second conveying belt 78, the second support table 82 is provided with a second material receiving groove 83, the second material receiving groove 83 is located directly below the second cutter 81 and extends along the length direction of the second support beam 79, the second material receiving groove 83 penetrates through the upper and lower end faces of the second support table 82, the second conveying belt 84 is located below the second support table 82, the second conveying belt 84 extends along the length direction of the second material receiving groove 83 and penetrates through the second slitting support plate 80, and the belt surface of the second conveying belt 84 is opposite to the slot of the second material receiving groove 83.

[0082] The number of the second conveying belts 78 is multiple, and the multiple second conveying belts 78 are arranged at intervals along the length direction of the second support beam 79, and each second cutter 81 is located between two second conveying belts 78, so that the second cutter 81 will not interfere with the second conveying belt 78. And the debris generated after the cutting of the second cutter 81 falls into the second material receiving groove 83 from between the two second conveying belts 78, and finally falls onto the second conveying belt 84. Since the second conveying belt 84 penetrates through the second slitting support plate 80, the second conveying belt 84 can convey the collected debris to the outside of the frame for recycling.
