Technical Field

[0001] This invention relates to a perfect binding machine, belonging to the technical field of perfect binding machines. Background Technology

[0002] Currently, the common method for perfect binding books involves placing the book block on a binding machine for compaction, then applying polyethylene glue to the book block, and finally sealing the book cover onto the book block. For example, the applicant's prior Chinese patent application CN214611289U discloses an automatic lifting mechanism for a perfect binding clamping machine, and prior Chinese patent application CN213413333U discloses a creasing device for a perfect binding machine. Furthermore, another prior Chinese patent application CN213949860U discloses an automatic book-retrieving device for a perfect binding machine, which clamps the book using clamping components and transports the book using driving components, thereby improving the automation level of the perfect binding machine. However, existing perfect binding machines lack a highly automated feeding structure. The book blocks to be bound are stacked loose sheets of paper, and there is currently no good method for continuously feeding multiple book blocks, causing the overall working efficiency of the perfect binding machine to be affected by the feeding efficiency, preventing a breakthrough.

The receiving drive wheel is connected to the receiving driven wheel through a receiving transmission belt, and the receiving platform is connected to the receiving transmission belt through a receiving fixing member.

[0009] The book block positioning mechanism includes a receiving frame and a lifting and moving device. The receiving frame is located downstream of a book block conveying mechanism, which conveys a book block clamp holding the book block to the receiving frame.

The support member is mounted on the lifting frame.

[0011] The translation mechanism includes a translation motor, a translation drive wheel connected to the power output end of the translation motor, and a translation driven wheel connected to the translation drive wheel via a translation transmission belt.

[0012] The support member includes a positioning post and a support plate. The positioning post protrudes upward from the plane of the support plate. A positioning hole is provided at the lower end of the book block clamp, and the positioning post can be inserted into the positioning hole.

[0013] The trolley mechanism includes a trolley base frame and a first feed clamping plate, a second feed clamping plate, a first feed motor, and a feed transmission assembly disposed on the trolley base frame. The first feed motor can drive the first feed clamping plate and the second feed clamping plate to move closer to each other or further away from each other through the feed transmission assembly. The feed transmission assembly is distributed at the left and right ends of the first feed clamping plate and the second feed clamping plate, thereby forming a first gap between the first feed clamping plate and the second feed clamping plate, so that the book block can be placed above and clamped between the first feed clamping plate and the second feed clamping plate, and can fall downward through the first gap.

[0014] The feed transmission assembly includes a first feed screw and a second feed screw; the first feed screw passes sequentially through a through hole in the first feed clamp and a second feed nut in the second feed clamp; the second feed screw passes sequentially through a through hole in the second feed clamp and a first feed nut in the first feed clamp; a first feed gear is provided on the first feed screw, and a second feed gear is provided on the second feed screw, and the first feed gear meshes with the second feed gear.

[0015] The feed transmission assembly further includes a third feed screw and a fourth feed screw.

The third feed screw is connected to the third feed nut on the second feed clamp, and the fourth feed screw is connected to the fourth feed nut on the first feed clamp.

[0016] The trolley base frame is connected to a feed transmission belt via a feed connector. The feed transmission belt is connected between the feed drive wheel and the feed driven wheel. The feed drive wheel is connected to the power output end of a second feed motor.

[0017] The glue-coating mechanism includes multiple glue-coating rollers, on which glue is applied. The trolley mechanism can hold the book block and move it above the glue-coating rollers, thereby applying glue to the lower end face of the book block.

[0018] The book cover sealing mechanism includes a sealing base frame and a lifting motor and a lifting frame mounted on the sealing base frame. The lifting frame is equipped with a first horizontal plate, a second horizontal plate, a support plate, a first sealing drive device, and a first sealing motor. The lifting motor drives the lifting frame to move up and down. The first and second horizontal plates support the book cover, forming a second gap between them. The first sealing motor drives the support plate to move vertically below the second gap and also drives the support plate to move away vertically below the second gap. The glued book core can be vertically placed on the book cover at a position vertically above the second gap. The first sealing drive device drives the first and second horizontal plates to move closer or further apart. A drop opening is provided on the sealing base frame, allowing the sealed book core to fall through the drop opening.

[0019] The power output end of the lifting motor is connected to a lifting screw, and a lifting nut is provided on the lifting frame and installed on the lifting screw.

[0022] An inclined guide plate is provided below the drop opening, and a receiving component is provided at the lower end of the guide plate; the receiving component includes a flip plate and a backing plate. The flip plate is connected to a flipping drive device. When the book block after the book cover is sealed slides down the guide plate onto the flip plate, the flipping drive device can drive the flip plate to flip, so that the book block after the book cover is sealed rests on the backing plate.

[0023] The book block clamp includes a base, a fixed clamp plate fixed on the base, and a movable clamp plate movably disposed on the base; a magnetic attraction device for adsorbing onto the base is provided on the lower end face of the movable clamp plate.

[0024] Using the above technical solution, the perfect binding machine of the present invention uses a feeding mechanism for feeding. The book block is pre-placed in a book block clamp. When the book block clamp is conveyed to the book block returning mechanism, a holding and waiting mechanism clamps the book block. A trolley mechanism moves towards the book block clamp and collides with it, pushing the clamp away from the returning mechanism. After the trolley mechanism receives the book block, the feeding mechanism resets and performs the next feeding operation. Simultaneously, the trolley mechanism sequentially sends the book block to the gluing mechanism for gluing and then to the cover sealing mechanism for cover sealing. The perfect binding machine of the present invention, through the book block clamp, facilitates the support and conveying of book blocks composed of stacked loose paper. The holding and waiting mechanism and the trolley mechanism work together to both clamp and transfer the book block and push the clamp away from the returning mechanism, solving the problem of inconvenient book block feeding in the prior art and effectively improving the production efficiency of the perfect binding machine.

[0049] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0050] like Figure 1-4 As shown, the perfect binding machine of the present invention includes a feeding mechanism 1, a trolley mechanism 2, an automatic opening and closing blade suction milling cutter mechanism 7, a glue application mechanism 3, a book cover feeding device 4, and a book cover sealing mechanism 5.

[0051] The feeding mechanism 1 is used to feed the book block, and the trolley mechanism 2 is used to clamp the book block conveyed by the feeding mechanism 1 and sequentially send the book block to the automatic opening and closing under-blade suction milling cutter mechanism 7, the glue-applying mechanism 3, and the book cover sealing mechanism 5. Figure 24 As shown, the automatic opening and closing blade suction milling cutter mechanism 7 and the glue-applying mechanism 3 are located below the running trajectory of the trolley mechanism 2. The automatic opening and closing blade suction milling cutter mechanism 7 is used to mill, flatten, and cut the perfect binding surface of the book block. The paper scraps cut off are sucked away by the centrifugal air below the milling cutter. The automatic opening and closing ensures that the cut edge covers the thickness of the book block, reducing paper scrap overflow. The glue-applying mechanism 3 is used to perform glue application, glue extrusion, smoothing, side glue application, and ironing operations, thereby providing a firm, uniform, and flat glue surface treatment for the perfect binding surface of the book block, providing a high-quality glue layer for subsequent cover application. The book cover feeding device 4 is used to roll and press the book cover and pneumatically suction the book cover to deliver it to the book cover sealing mechanism 5. The book cover sealing mechanism 5 is used to seal the book block with a book cover.

[0052] like Figure 5-8 As shown, the feeding mechanism 1 includes a book block clamp 11 for placing the book block 100, a book block conveying mechanism 12 for conveying the book block clamp 11, a book block returning mechanism 13 for receiving the book block clamp 11, and a clamping and guarding mechanism 14 for clamping and conveying the book block. The book block clamp 11 is provided with a vertical receiving groove 110, in which the book block 100 can be placed vertically. One end of the receiving groove 110 is open, and the other end is provided with a blocking part 111, so that the book block can be moved out of the open end 112 of the receiving groove 110. In this embodiment, as... Figure 23 As shown, the book block clamp 11 includes a base 113, a fixed clamping plate 114 fixed to the base 113, and a movable clamping plate 115 movably disposed on the base 113. The receiving groove 110 is formed between the fixed clamping plate 114 and the movable clamping plate 115. A magnetic attraction device 116 for adsorbing onto the base is provided on the lower end face of the movable clamping plate 115. The magnetic attraction device 116 can be a high-power magnet. By moving the movable clamping plate 115, it is clamped onto the book block. The magnetic attraction device 116 can fix the movable clamping plate 115 to the base 113, thereby providing a holding force for the book block. At the same time, the holding force is not too large and will affect subsequent operations, so that the book block can be smoothly detached from the book block clamp 11.

[0053] The book block conveying mechanism 12 includes a conveyor belt for conveying the book block clamp 11 containing the book block to the book block returning mechanism 13.

[0054] In one embodiment of the present invention, the book block positioning mechanism 13 includes a receiving platform 131 and a receiving motor 132. The receiving platform 131 is located downstream of the book block conveying mechanism 12. A receiving drive wheel 133 is provided at the power output end of the receiving motor 132. The receiving drive wheel 133 is connected to the receiving driven wheel 135 via a receiving transmission belt 134. The receiving platform 131 is connected to the receiving transmission belt 134 via a receiving fixing member 136. The receiving motor 132 can drive the receiving platform 131 to move closer to or away from the book block conveying mechanism 12. A baffle 131a is provided on the side of the receiving platform 131 away from the book block conveying mechanism 12. When the conveyor belt delivers the book block clamp 11 onto the receiving platform 131, the baffle 131a can block and limit the book block clamp 11.

[0055] The clamping and waiting mechanism 14 is used to clamp the book block 100. After the clamping and waiting mechanism 14 clamps the book block 100, the trolley mechanism 2 moves towards the book block clamp 11 and collides with the book block clamp 11, causing the book block clamp 11 to be pushed away from the receiving platform 131. Specifically, the clamping and waiting mechanism 14 includes a clamping component and a conveying component, and the clamping component is disposed on the conveying component. The clamping component includes a clamping base 141, a first feeding clamp 142, a second feeding clamp 143, and a first feeding motor 144. The first feeding motor 144 is mounted on the clamping base 141. The power output end of the first feeding motor 144 is connected to a feeding screw 145. The feeding screw 145 is provided with a first nut 146 and a second nut 147. When the feeding screw 145 rotates, the first nut 146 and the second nut 147 can move closer to or further away from each other. The first feeding clamp 142 and the second feeding clamp 143 are respectively fixed to the first nut 146 and the second nut 147. In this embodiment, the feeding screw 145 is provided with a forward thread section and a reverse thread section, and the first nut 146 and the second nut 147 are located on the forward thread section and the reverse thread section, respectively.

[0056] The conveying component includes a second feeding motor 148, a feeding drive wheel 148a disposed at the power output end of the second feeding motor 148, and a feeding driven wheel 148c connected to the feeding drive wheel 148a via a feeding transmission belt 148b. The clamping base frame 141 is connected to the feeding transmission belt 148b via a feeding fixing member 148d.

[0057] like Figure 18-22As shown, in another embodiment of the present invention, the book block repositioning mechanism includes a receiving frame 137 and a lifting and moving device. The receiving frame 137 is located downstream of the book block conveying mechanism 12. The book block conveying mechanism is used to convey the book block clamp 11 holding the book block to the receiving frame 137. A step portion 137a is provided on the receiving frame 137, which can block and position the book block clamp 11. Two through slots 137b are provided on the receiving frame 137. The through groove 137b starts from one side of the stepped portion 137a and extends to the other side of the stepped portion 137a; the lifting and moving device includes two support members 138a, a lifting mechanism 138 for raising and lowering the support members 138a, and a translation mechanism 139 for moving the support members 138a. The lifting mechanism 138 can lift the support members 138a upward to lift the book core clamp 11, and the translation mechanism 139 can move the support members 138a along the through groove 137b.

[0058] The lifting mechanism 138 includes a lifting base frame 138b, a lifting motor 138c mounted on the lifting base frame 138b, a lifting screw 138d connected to the power output end of the lifting motor 138c, a lifting nut 138e mounted on the lifting screw 138d, and a lifting frame 138f fixed to the lifting nut 138e. The support member 138a is mounted on the lifting frame 138f.

[0059] The translation mechanism 139 includes a translation motor 139a, a translation drive wheel 139b connected to the power output end of the translation motor 139a, and a translation driven wheel 139c connected to the translation drive wheel 139b via a translation transmission belt 139d. The lifting base frame 138b is connected to the translation transmission belt 139d. The translation mechanism 139 can move the book core clamp 11 to a position where the book core can be clamped by the clamping and waiting mechanism 14. At this position, the book core clamp 11 is positioned so that it can be collided with by the trolley mechanism 2.

[0060] The support member 138a includes a positioning post 138a1 and a support plate portion 138a2. The positioning post 138a1 protrudes upward from the plane of the support plate portion 138a2. A positioning hole 119 is provided at the lower end of the book block clamp 11, and the positioning post 138a1 can be inserted into the positioning hole 119. Before the trolley mechanism 2 collides with the book block clamp 11, the positioning post 138a1 is withdrawn outward from the positioning hole 119, thereby allowing the book block clamp 11 to be knocked away from the receiving frame 137 by the trolley mechanism 2.

[0061] like Figure 9 , 10As shown, the trolley mechanism 2 includes a trolley base frame 21 and a first feed clamping plate 22, a second feed clamping plate 23, a first feed motor 24, and a feed transmission assembly disposed on the trolley base frame 21. The first feed motor 24 can drive the first feed clamping plate 22 and the second feed clamping plate 23 to move closer to or further away from each other through the feed transmission assembly. The feed transmission assembly is distributed at the left and right ends of the first feed clamping plate 22 and the second feed clamping plate 23, thereby forming a first gap 20 between the first feed clamping plate 22 and the second feed clamping plate 23, allowing the book block to be placed above and clamped between the first feed clamping plate 22 and the second feed clamping plate 23, and to fall downwards through the first gap 20.

[0062] In this embodiment, the feed transmission assembly includes a first feed screw 251, a second feed screw 252, a third feed screw 253, and a fourth feed screw 254 that are interconnected. The first feed screw 251 passes sequentially through a through hole on the first feed clamp 22 and a second feed nut 231 on the second feed clamp 23, thus only driving the second feed clamp 23 to move. The second feed screw 252 passes sequentially through a through hole on the second feed clamp 23 and a first feed nut 221 on the first feed clamp 22, thus only driving the first feed clamp 22 to move. A first feed gear 255 is provided on the first feed screw 251, and a second feed gear 256 is provided on the second feed screw 252, with the first feed gear 255 meshing with the second feed gear 256. The first feed screw 251 is connected to the third feed screw 253 via the first transmission pulley mechanism 201, and the second feed screw 252 is connected to the fourth feed screw 254 via the second transmission pulley mechanism 202. The third feed screw 253 is connected to the third feed nut 257 on the second feed clamping plate 23, and the fourth feed screw 254 is connected to the fourth feed nut 258 on the first feed clamping plate 22. The structure of the above-mentioned feed transmission assembly enables transmission at both ends of the first feed clamping plate 22 and the second feed clamping plate 23, so that the first feed clamping plate 22 and the second feed clamping plate 23 are subjected to force balance, and the book block is firmly clamped. At the same time, it also ensures that the first gap 20 between the first feed clamping plate 22 and the second feed clamping plate 23 is not obstructed vertically above and below, so that the book block can be freely inserted into the first gap 20 and clamped, and can fall freely from the first gap 20 after being released.

[0063] The trolley base frame 21 is connected to a feed transmission belt 27 via a feed connector 211. The feed transmission belt 27 is connected between the feed drive wheel 28 and the feed driven wheel 29. The feed drive wheel 28 is connected to the power output end of a second feed motor 26.

[0064] The glue-coating mechanism 3 includes multiple glue-coating rollers 31. Glue is attached to the glue-coating rollers 31. The trolley mechanism 2 can hold the book block and move it above the glue-coating rollers, thereby applying glue to the lower end face of the book block.

[0065] The binding machine also includes a cover conveyor 41 and a cover feeding device 4. After the cover is placed on the cover conveyor 41, it is fed to the cover feeding device 4 by the pressure roller 42. Figure 11 As shown, the book cover feeding device 4 includes a book cover feeding base 43, an adsorption device 44 disposed on the book cover feeding base 43, and a book cover feeding motor 45 for driving the book cover feeding base 43 to move. The power output end of the book cover feeding motor 45 is connected to a book cover feeding drive wheel 46. The book cover feeding drive wheel 46 is connected to a book cover feeding driven wheel 48 through a book cover feeding transmission belt 47. The book cover feeding transmission belt 47 is connected to the book cover feeding base 43 through a book cover feeding connector 49. After the adsorption device 44 sucks in air to adsorb the book cover, the book cover feeding base 43 is driven to move by the book cover feeding motor 45, and the book cover is delivered to the book cover sealing mechanism 5.

[0066] like Figure 12-16 As shown, the book cover sealing mechanism 5 includes a sealing base frame 51 and a lifting motor 52 and a lifting frame 53 disposed on the sealing base frame 51. A first horizontal plate 54, a second horizontal plate 55, a support plate 56, a first sealing drive device, and a first sealing motor 57 are disposed on the lifting frame 53.

[0067] The lifting motor 52 is used to drive the lifting frame 53 to move up and down. Specifically, the power output end of the lifting motor 52 is connected to the lifting screw 521, and a lifting nut 522 is provided on the lifting frame 53. The lifting nut 522 is installed on the lifting screw 521.

[0068] The first horizontal plate 54 and the second horizontal plate 55 are used to support the book cover, forming a second gap 50 between the first horizontal plate 54 and the second horizontal plate 55. The first packaging motor 57 is used to drive the support plate 56 to move vertically below the second gap 50, and to drive the support plate 56 to move away vertically below the second gap 50. Specifically, a first packaging screw 571 is connected to the power output end of the first packaging motor 57, and a first packaging nut 572 is provided on the support plate 56. The first packaging nut 572 is installed on the first packaging screw 571.

[0069] When the tray 56 is below the second gap 50, the book cover is sent above the first horizontal plate 54 and the second horizontal plate 55. After the glued book core is placed vertically on the book cover at a position vertically above the second gap 50, the book core partially presses the book cover into the second gap 50. The first packaging drive device drives the first horizontal plate 54 and the second horizontal plate 55 to move closer to each other, thereby clamping the book cover and the book core, so that the book cover is glued to the book core.

[0070] After the book cover sealing operation is completed, the first sealing motor 57 drives the tray 56 to move vertically below the second gap 50. A drop opening 510 is provided on the sealing base frame 51, and the book core after the book cover is sealed can fall into the drop opening 510.

[0071] In this embodiment, the first packaging drive device includes a second packaging motor 581 and a third packaging motor 582; the power output end of the second packaging motor 581 is connected to a second packaging lead screw 583, and a second packaging nut 584 is provided on the first horizontal plate 54, and the second packaging nut 584 is mounted on the second packaging lead screw 583; the power output end of the third packaging motor 582 is connected to a third packaging lead screw 585, and a third packaging nut 586 is provided on the second horizontal plate 55, and the third packaging nut 586 is mounted on the third packaging lead screw 585.

[0072] like Figure 17 As shown, an inclined guide plate 61 is provided below the drop opening, and a receiving component is provided at the lower end of the guide plate 61. The receiving component includes a flipping plate 62 and a backing plate 63. The flipping plate 62 is connected to a flipping drive device. When the book core with the book cover slid down along the guide plate 61 onto the flipping plate 62, the flipping drive device can drive the flipping plate 62 to flip, so that the book core with the book cover rests against the backing plate 63. The flipping drive device includes a flipping motor 64, a swing rod 65 connected to the power output end of the flipping motor 64, and a connecting rod 66 hinged to the swing rod 65. The connecting rod 66 is hinged to the flipping plate 62. The backing plate 63 is slidably disposed on the base plate 67, and a tension spring 68 is connected to the backing plate 63 to apply a pulling force toward the guide plate 61 to the backing plate 63 at all times.

[0073] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
