Description

Technical Field

[0001] The present invention relates to the technical field of coil binding equipment, and in particular to a paper coil binding machine and a paper coil binding process. Background Art

[0002] Currently, loose-leaf binding can be categorized into glue binding, staple binding, and ring binding. Ring binding generally involves inserting a binding coil through the binding hole of the book, allowing the coil to hook onto the book, thus preventing it from falling off. During binding, a worker first inserts the connecting portion of the binding coil through the binding hole of the book, allowing the coil to hook onto the book, and then uses a binding coil welding mechanism to weld the plate and connecting portion of the binding coil.

[0003] Existing coil binding equipment is mainly used for binding iron coils or binding glue coils, while binding paper coils are more environmentally friendly than binding iron coils and binding glue coils, and are therefore more in line with the future development trend of binding coils. However, since existing coil binding equipment is not suitable for binding binding paper coils, it is necessary to develop a device that can be used for binding binding paper coils.

[0060] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0061] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0062] like Figure 1-10 As shown, the present invention discloses a paper coil binding machine, including a frame 10, and a paper coil loading mechanism 20, a paper coil cutting mechanism 30, a paper coil moving mechanism 40, and a paper coil welding mechanism 50 arranged on the frame 10 in sequence along the conveying direction of the binding paper coil 90, and a book moving mechanism 60 is provided on one side of the paper coil moving mechanism 40.

[0063] The paper coil feeding mechanism 20 includes a first guide member 21, a first driving member 22 and a first driving unit 23. The first driving unit 23 can drive the first driving member 22 to move so that the first driving member 22 can transport the binding paper coil 90 on the first guide member 21 to the paper coil transferring mechanism 40.

[0064] The paper coil cutting mechanism 30 includes a cutter 31 and a cutting drive device 33 . The cutting drive device 33 can drive the cutter 31 to move so that the cutter 31 cuts the binding paper coil 90 between the paper coil feeding mechanism 20 and the paper coil moving mechanism 40 .

[0065] The paper coil material moving mechanism 40 includes a second guide member 41 , a second driving member 42 and a second driving unit 43 . The second driving unit 43 can drive the second driving member 42 to move, so that the second driving member 42 drives the binding paper coil 90 to move along the second guide member 41 .

[0066] The book moving mechanism 60 includes a third driving member 61 and a third driving unit 62. The third driving unit 62 can drive the third driving member 61 to move, so that the third driving member 61 drives the book 100 assembled with the binding paper coil 90 to move to one side of the paper coil welding mechanism 50.

[0067] The paper coil welding mechanism 50 can weld the plate portion 92 and the connecting portion 93 on the binding paper coil 90 .

[0068] like Figure 1-3As shown, the first driving member 22 is a conveying gear, which is arranged below, above or on one side of the first guide member 21. The conveying gear in the present invention is preferably arranged below the first guide member 21. The first driving unit 23 is a first motor, which can drive the conveying gear to rotate so that the teeth 221 on the conveying gear push the binding paper coil 90 to move forward. Specifically, a gap is provided between two adjacent ring portions 91, and the teeth 221 can extend into the gap to push the ring portion 91 to move, so that the ring portion 91 drives the binding paper coil 90 to move, which can It is understood that the first driving member 22 can also be replaced by a first push rod (not shown), and the first driving unit 23 can also be replaced by a first driving module and a second driving module. Specifically, the push rod is arranged on the first driving module, and the first driving module is arranged on the second driving module. During operation, the first driving module first drives the push rod to be inserted into the gap between the two adjacent ring portions 91, and then the second driving module drives the first driving module to move forward, so that the push rod pushes the ring portion 91 to move forward, and the ring portion 91 drives the binding paper coil 90 to move forward along the first guide member 21.

[0069] like Figure 1-3 As shown, the first guide member 21 is a guide rod, the axis of the guide rod extends in the front-to-back direction, the ring portion 91 on the binding paper coil 90 can be sleeved outside the guide rod, and the binding paper coil 90 can move forward along the guide rod. Specifically, a limiting plate 211 is provided on the circumferential outer wall of the guide rod, the width of the limiting plate 211 is less than the diameter of the guide rod, the limiting plate 211 extends in the front-to-back direction, and the guide rod is connected to the frame 10 through the limiting plate 211. During production, the limiting plate 211 is located between the plate portion 92 on the binding paper coil 90 and the connecting portion 9 3, the limiting plate 211 can limit the binding paper coil 90 from rotating around the guide rod. It can be understood that the first guide member 21 can also adopt a guide groove (not shown), which extends in the front-to-back direction. The bottom or side wall of the guide groove is provided with a clearance groove (not shown). The clearance groove allows the teeth 221 on the conveying gear to extend into the guide groove. When the guide groove is used, the ring portion 91 on the binding paper coil 90 is placed in the guide groove, and the teeth 221 of the conveying gear extend into the guide groove to drive the ring portion 91 to move, so that the ring portion 91 drives the binding paper coil 90 to move forward along the guide groove.

[0070] like Figure 1-3As shown, the cutter 31 includes a fixed cutter 312 and a movable cutter 311. The fixed cutter 312 is provided with a knife groove (not shown). The cutting drive device 33 can drive the cutter 31 to move relative to the fixed cutter 312. The cooperation between the movable cutter 311 and the knife groove cuts off the plate portion 92 on the binding paper coil 90. A waste channel 11 is connected below the knife groove. The lower end of the waste channel 11 is connected to a waste discharge chute 12 arranged obliquely downward. During production, the plate portion 92 on the binding paper coil 90 passes between the movable cutter 311 and the fixed cutter 312. The waste cut out by the movable cutter 311 enters the knife groove and falls into the waste channel 11, and finally flows out from the waste discharge chute 12.

[0071] The cutting drive device 33 can be rotatably mounted on the frame 10. The movable rod 331 of the cutting drive device 33 is rotatably connected to one end of the movable cutter 311, and the middle part of the cutter 31 is rotatably connected to the fixed cutter 312. Specifically, the cutting drive device 33 is a cylinder. It can be understood that the movable rod 331 can be set to be fixedly connected to the movable cutter 311. When the movable rod 331 moves up and down in a straight line, it can drive the movable cutter 311 to move up and down linearly relative to the knife groove. The cutting drive device 33 can also adopt a screw rod + motor structure, and scissors can also be used in the paper coil cutting mechanism 30 instead of the cutter 31.

[0072] like Figure 1-4 As shown, the second driving member 42 is a synchronous belt, which extends in the front-to-back direction. A plurality of first material shifting blocks 421 are spaced apart on the circumferential outer surface of the synchronous belt. The second driving unit 43 is a second motor, which can drive the synchronous belt to rotate so that the first material shifting block 421 pushes the binding paper coil 90 to move forward. During operation, the first material shifting block 421 can extend into the gap to push the ring portion 91 to move, thereby causing the ring portion 91 to drive the binding paper coil 90 to move.

[0073] It should be noted that, in the present invention, the first driving member 22 and the second driving member 42 can work synchronously, so that the binding paper coil 90 can move smoothly from the first guide member 21 to the second guide member 41, thereby preventing the binding paper coil 90 from being out of sync with the second driving member 42 during movement and causing material jamming.

[0074] like Figure 1-4As shown, the second guide member 41 is a guide plate, which is arranged above the second driving member 42. The guide plate extends in the front-to-back direction, and a guide slot 411 is formed between the lower surface of the guide plate and the upper surface of the frame 10. The plate portion 92 on the binding paper coil 90 can be inserted into the guide slot 411 and slide in the front-to-back direction. During production, the side edge of the guide plate close to the book-moving mechanism 60 extends into the loop portion 91 on the binding paper coil 90. In the process of the synchronous belt driving the binding paper coil 90 to move forward along the guide plate, the upper surface of the synchronous belt can support the loop portion 91, thereby preventing the binding paper coil 90 from falling.

[0075] A positioning plate 44 is provided between the guide plate and the book moving mechanism 60. The positioning plate 44 extends in the front-to-back direction. The height of the positioning plate 44 is lower than the height of the guide plate. A guide gap 45 is formed between the positioning plate 44 and the guide plate. The second driving member 42 is located between the guide gap 45 and the guide slide 411. The loop portion 91 on the binding paper coil 90 can move forward along the guide gap 45. The lower surface of the book 100 can slide against the upper surface of the positioning plate 44. By providing the positioning plate 44, a guide gap 45 is formed between the positioning plate 44 and the guide plate. There is a guide gap 45, so that when the second driving member 42 drives the binding paper coil 90 to move forward, the ring portion 91 on the binding paper coil 90 can move forward along the guide gap 45, and the guiding effect of the guide gap 45 makes the movement of the binding paper coil 90 more stable; by setting the height of the positioning plate 44 to be lower than the height of the guide plate, the lower half of the ring portion 91 can be slidably abutted against the positioning plate 44, and with the support of the synchronous belt and the guide slide 411, the entire binding paper coil 90 has three support points, and the binding paper coil 90 is more stable when moving forward.

[0076] It is understandable that the second driving member 42 can also be replaced by a second push rod (not shown), and the second driving unit 43 can also be replaced by the first driving module and the second driving module, so that the movement mode and principle of the second push rod are the same as the movement mode and principle of the first push rod.

[0077] like Figure 1 and Figure 5As shown, the third driving member 61 is a conveyor belt, and a plurality of second material shifting blocks 611 are spaced apart on the circumferential outer surface of the conveyor belt. The third driving unit 62 is a third motor. The third motor can drive the conveyor belt to rotate so that the second material shifting block 611 pushes the book 100 to move forward. The extension direction of the conveyor belt is parallel to the extension direction of the synchronous belt, and the conveyor belt and the synchronous belt move synchronously, so that the book 100 and the binding paper coil 90 assembled on the book 100 move forward synchronously. It can be understood that the third driving member 61 can also adopt a third push rod (not shown), and a third pushing block (not shown) is arranged on the third push rod. During production, the third push rod drives the third pushing block to move forward, so that the third pushing block pushes the book 100 to move forward.

[0078] like Figure 1 and Figure 5 As shown, a book positioning mechanism 70 is provided on the side of the book moving mechanism 60 away from the paper coil welding mechanism 50, and the book positioning mechanism 70 includes a fourth driving member 71 and at least one fourth driving unit 72, and the fourth driving unit 72 can drive the fourth driving member 71 to move so that the fourth driving member 71 is in contact with the side wall of the book 100 on the book moving mechanism 60; by arranging the book positioning mechanism 70 on the side of the book positioning mechanism 70 away from the paper coil welding mechanism 50, during production, the fourth driving unit 72 drives the fourth driving member 71 to move toward the paper coil welding mechanism 50, so that the fourth driving member 71 is in contact with the side wall of the book 100, thereby correcting the position of the book 100, avoiding deviation in welding of the binding paper coil 90 caused by the skewed position of the book 100, and improving the welding accuracy of the binding paper coil 90.

[0079] The fourth driving member 71 is a movable positioning plate, and a positioning surface 711 is provided on the side of the movable positioning plate facing the paper coil welding mechanism 50. The fourth driving unit 72 can drive the movable positioning plate to move relative to the paper coil welding mechanism 50 so that the positioning surface 711 is in contact with the side wall of the book 100. Specifically, the movable positioning plate extends in the front-to-back direction, and the rear end of the movable positioning plate extends to one side of the paper coil material moving mechanism 40. The positioning surface 711 is perpendicular to the horizontal plane. The driving end 571 of the fourth driving unit 72 is connected to the movable positioning plate. The fourth driving unit 72 is a cylinder. Exemplarily, the number of the fourth driving units 72 is two, and the two fourth driving units 72 are arranged side by side in the front-to-back direction.

[0080] The book positioning mechanism 70 also includes a mounting seat 73, a movable seat 74 and an adjusting screw 75. The movable seat 74 is slidably mounted on the mounting seat 73 through a guide column 76. The guide column 76 extends in the left and right directions. The adjusting screw 75 is threadedly connected to the mounting seat 73. The central axis of the adjusting screw 75 is parallel to the central axis of the guide column 76. One end of the adjusting screw 75 is rotatably connected to the movable seat 74. The fourth driving member 71 is mounted on the guide column 76. The fourth driving unit 72 is mounted on the movable seat 74. When adjusting, the adjusting screw 75 is rotated. The fourth drive member 71 is moved to its furthest position by the fourth drive unit 72. The fourth drive unit 72 is adjusted to extend or retract relative to the paper coil welding mechanism 50 along its axial direction. The fourth drive unit 72 is adjusted to extend or retract relative to the paper coil welding mechanism 50. The fourth drive unit 71 is adjusted to its furthest position by the fourth drive unit 72. This is suitable for positioning books 100 of different sizes. For example, when the book 100 is wide, the fourth drive unit 72 can be adjusted to be farther away from the paper coil welding mechanism 50. When the book 100 is narrow, the fourth drive unit 72 can be adjusted to be closer to the paper coil welding mechanism 50.

[0081] like Figure 1 and Figure 6-10 As shown, the paper coil welding mechanism 50 includes a die head 51, a welding head 52 and at least one welding drive device 53. In the present invention, the number of welding drive devices 53 can be set to two or more, and two or more welding drive devices 53 are spaced apart along the front-to-back direction. The use of multiple welding drive devices 53 can be suitable for welding binding paper coils 90 with longer lengths. The welding drive device 53 can drive the die head 51 to move relative to the welding head 52. The welding head 52 is connected to an ultrasonic generator 54. The cooperation between the die head 51 and the welding head 52 can weld the connecting portion 93 and the plate portion 92 of the binding paper coil 90.

[0082] It should be noted that in the binding paper coil 90 of the present invention, the side surface of the plate portion 92 facing the connecting portion 93, the inner surface of the ring portion 91, and the side surface of the connecting portion 93 facing the plate portion 92 are all coated with a glue layer, and the glue layer enables the plate portion 92 and the connecting portion 93 to be fixed by ultrasonic welding.

[0083] The welding drive device 53 includes a lifting seat 55, a transmission assembly 56 and a welding drive unit 57. The lifting seat 55 is mounted on the frame 10 by sliding up and down through a slide bar 551. The welding drive unit 57 can drive the lifting seat 55 to move up and down through the transmission assembly 56. The die head 51 is arranged above the welding head 52. The die head 51 is mounted on the lifting seat 55, and the die head 51 can move up and down with the lifting seat 55. It can be understood that the die head 51 can also be arranged below the welding head 52. By setting the lifting seat 55, the transmission assembly 56 and the welding drive unit 57, the welding drive unit 57 can be driven by the lifting seat 55. 7, the welding drive device 53 is composed of a lifting seat 55 that is slidably installed on the frame 10, and the die head 51 is installed on the lifting seat 55. The welding drive unit 57 can drive the lifting seat 55 to move up and down through the transmission component 56, so that the lifting seat 55 drives the die head 51 to move. The transmission component 56 is used to transmit the power output by the welding drive unit 57 to the lifting seat 55, so that the welding drive unit 57 can be arranged horizontally or obliquely on one side of the lifting seat 55, avoiding the welding drive unit 57 occupying the space directly above or below the lifting seat 55, reducing the overall height of the paper coil welding mechanism 50, and facilitating assembly and maintenance.

[0084] It is understandable that the die head 51 and the lifting seat 55 can be set in a separate manner or in an integrally formed manner.

[0085] The transmission assembly 56 includes a swinging member 561 and a connecting rod 562. The swinging member 561 has a first swing arm 5611 and a second swing arm 5612 set at an angle, and the angle θ between the first swing arm 5611 and the second swing arm 5612 is ≥90°. The swinging member 561 is rotatably connected to the frame 10 through a first rotating shaft 563, the first swing arm 5611 is rotatably connected to the driving end 571 of the welding drive unit 57 through a second rotating shaft 564, the second swing arm 5612 is rotatably connected to one end of the connecting rod 562 through a third rotating shaft 565, and the other end of the connecting rod 562 is rotatably connected to the lifting seat 55 through a fourth rotating shaft 566. The welding drive unit 57 is rotatably connected to the frame 10 through a fifth rotating shaft 567. Specifically, the welding drive unit 57 is installed on the frame at an angle. The welding drive unit 57 is a cylinder. It can be understood that the welding drive unit 57 can also be installed on the frame 10 horizontally. The welding drive unit 57 can also adopt a screw + motor structure.

[0086] It should also be noted that the structure of the swinging member 561 + cylinder can also be replaced by an eccentric wheel (not shown) + rotating motor (not shown). During operation, the rotating motor drives the eccentric wheel to rotate. While the eccentric wheel drives the connecting rod 562 to rotate, the eccentric wheel also drives the connecting rod 562 to move up and down, thereby also achieving the effect of the swinging member 561 + cylinder structure.

[0087] like Figure 1 and Figure 6-10 As shown, the frame 10 is also provided with a paper coil positioning mechanism 80, and the paper coil positioning mechanism 80 includes a first positioning seat 81, a second positioning seat 82 and a positioning drive unit 83. The positioning drive unit 83 can drive the first positioning seat 81 to move relative to the second positioning seat 82. The cooperation between the first positioning seat 81 and the second positioning seat 82 can position the ring portion 91 on the binding paper coil 90.

[0088] The first positioning seat 81 is arranged above the second positioning seat 82, and the first positioning seat 81 is provided with a first positioning groove 811, and the second positioning seat 82 is provided with a second positioning groove 821 corresponding to the second positioning seat 82, and the first positioning groove 811 and the second positioning groove 821 are extended in the front-to-back direction, and the second positioning seat 82 is provided with a plate guide surface 822 and a circle guide surface 823 at one end close to the paper coil material moving mechanism 40, and the plate guide surface 822 and the circle guide surface 823 are both inclined downward from front to back, and the front end of the plate guide surface 822 extends to the upper surface of the second positioning seat 82, and the circle guide surface 823 is provided with a plate guide surface 822 and a circle guide surface 823. The front end of the surface 823 extends to the second positioning groove 821; by providing a plate guide surface 822 and a circle guide surface 823 at one end of the second positioning seat 82 close to the paper coil moving mechanism 40, the plate guide surface 822 and the circle guide surface 823 are both inclined downward from front to back, so that when the paper coil moving mechanism 40 pushes the binding paper coil 90 to move forward, the guiding effect of the plate guide surface 822 and the circle guide surface 823 is utilized to enable the plate portion 92 on the binding paper coil 90 to slide smoothly to the top of the second positioning seat 82, and the circle portion 91 on the binding paper coil 90 to slide smoothly into the second positioning groove 821.

[0089] Specifically, the ring guide surface 823 is a downwardly concave arc surface, the first positioning groove 811 and the second positioning groove 821 are both arc-shaped positioning grooves, the second positioning groove 821 passes through the front end surface of the second positioning seat 82, and the positioning drive unit 83 is a cylinder. By setting the second positioning groove 821 to pass through the front end surface of the second positioning seat 82, the welded binding paper coil 90 can continue to move forward along the second positioning groove 821 and unload.

[0090] The second positioning seat 82 is arranged between the die head 51 and the welding head 52. A long hole 824 is also provided on the second positioning seat 82. The long hole 824 is located on one side of the second positioning groove 821. The long hole 824 passes through the upper and lower surfaces of the second positioning seat 82. The long hole 824 extends in the front and back directions. The upper end of the welding head 52 extends into the long hole 824. During welding, the plate portion 92 on the binding paper coil 90 is located directly above the long hole 824.

[0091] It should be noted that the present invention can set a sensor on the frame 10. When the sensor detects that the book 100 moves to one side of the paper coil welding mechanism 50, the book moving mechanism 60 stops moving, and then the paper coil welding mechanism 50 welds the binding paper coil 90.

[0092] The working principle of the paper coil binding machine of the present invention:

[0093] The first driving unit 23 drives the first driving member 22 to rotate, and the first driving member 22 pushes the binding paper coil 90 on the first guide member 21 onto the second guide member 41. At the same time, the second driving unit 43 drives the second driving member 42 to rotate, and the second driving member 42 pushes the binding paper coil 90 to continue moving along the second guide member 41 for a distance.

[0094] The cutting drive device 33 cuts off the binding paper coil 90 between the paper coil feeding mechanism 20 and the paper coil moving mechanism 40;

[0095] The worker passes the connection portion 93 of the cut binding paper coil 90 upward through the binding hole of the booklet 100 so that the coil portion 91 is partially inserted into the binding hole.

[0096] The second driving unit 43 and the third driving unit 62 operate simultaneously. The second driving unit 42 drives the binding paper coil 90 to move forward into the second positioning groove 821, and positions the plate portion 92 of the binding paper coil 90 directly above the long hole 824. At the same time, the third driving unit 61 drives the booklet 100 to move toward one side of the paper coil welding mechanism 50.

[0097] The fourth driving unit 72 drives the fourth driving member 71 to move toward the side close to the paper coil welding mechanism 50, so that the fourth driving member 71 abuts against the side wall of the book 100, and the position of the book 100 is corrected;

[0098] The welding drive unit 57 pushes the first swing arm 5611, and the first swing arm 5611 drives the second swing arm 5612 to rotate, and the second swing arm 5612 drives the connecting rod to move downward, and the connecting rod drives the lifting seat to move downward, and the lifting seat drives the die head 51 to move downward, and the die head 51 presses the connecting part 93 to move downward, so that the connecting part 93 and the plate part 92 are clamped between the die head 51 and the welding head 52, and the ultrasonic generator 54 is started to make the die head 51 and the welding head 52 weld the connecting part 93 and the plate part 92. After the welding is completed, the third drive member 62 pushes the book 100 and the welded binding paper coil 90 to move forward and unload.

[0099] The present invention further discloses a paper coil binding process, wherein the paper coil binding process adopts the paper coil binding machine, and the paper coil binding process comprises the following steps:

[0100] Step 1: feeding, the paper coil feeding mechanism 20 conveys a certain length of binding paper coil 90 to the paper coil moving mechanism 40, wherein the length of the binding paper coil 90 conveyed each time by the paper coil feeding mechanism 20 is greater than or equal to the length of the book 100;

[0101] Step 2: Cutting, the binding paper coil 90 outputted by the paper coil feeding mechanism 20 is cut by the paper coil cutting mechanism 30, wherein the paper coil cutting mechanism 30 cuts off the plate portion 92 on the binding paper coil 90;

[0102] Step 3: Assemble. Pass the connecting portion 93 of the cut binding paper coil 90 through the binding hole of the booklet 100 so that the coil portion 91 is partially inserted into the binding hole. The connecting portion 93 can be passed through the binding hole of the booklet 100 manually or automatically.

[0103] Step 4: Material transfer: The booklet 100 assembled with the binding paper coil 90 is simultaneously transferred forward to one side of the paper coil welding mechanism 50 by the paper coil transfer mechanism 40 and the booklet transfer mechanism 60. The paper coil transfer mechanism 40 pushes the binding paper coil 90 forward to the second positioning groove 821, so that the connecting portion 93 and the plate portion 92 are located between the die head 51 and the welding head 52 on the paper coil welding mechanism 50. The booklet transfer mechanism 60 pushes the booklet 100 forward to one side of the paper coil welding mechanism 50.

[0104] Step 5: Welding. The connecting portion 93 and the plate portion 92 on the binding paper coil 90 are welded by the paper coil welding mechanism 50. The die head 51 on the paper coil welding mechanism 50 presses the connecting portion 93 downward, so that the die head 51 and the welding head 52 clamp the connecting portion 93 and the plate portion 92, and ultrasonic welding is used to weld the connecting portion 93 and the plate portion 92.

[0105] Step 6: Cutting the welded binding paper coils 90 and the book 100. When the book moving mechanism 60 pushes the next book 100 forward, the book moving mechanism 60 also pushes the book 100 on which the welding of the binding paper coils 90 has been completed to cut the welded binding paper coils 90.

[0106] Step 7: Repeat steps 1 to 6 above to bind the book 100 times.

[0107] In step four, after the booklet moving mechanism 60 pushes the booklet 100 forward to the paper coil welding mechanism 50, the booklet 100 is positioned by the booklet positioning mechanism 70. During positioning, the movable positioning plate on the booklet positioning mechanism 70 abuts against the side wall of the booklet 100.

[0108] In summary, the present invention sequentially arranges a paper coil feeding mechanism 20, a paper coil cutting mechanism 30, a paper coil moving mechanism 40, and a paper coil welding mechanism 50 on a frame 10. A book moving mechanism 60 is provided on one side of the paper coil moving mechanism 40. During production, the first driving member 22 on the paper coil feeding mechanism 20 first conveys the binding paper coil 90 on the first guide member 21 to the second guide member 41, and then the cutting knife 31 on the paper coil cutting mechanism 30 cuts the binding paper coil 90. Next, the connecting portion 60 is connected to the paper coil feeding mechanism 20. 93 passes through the binding hole on the book 100, so that the ring part 91 is partially inserted into the binding hole, and then the second driving member 42 on the paper coil moving mechanism 40 and the third driving member 61 on the book moving mechanism 60 synchronously transport the book 100 assembled with the binding paper coil 90 to one side of the paper coil welding mechanism 50, and finally the paper coil welding mechanism 50 welds the connecting part 93 and the plate part 92, thereby realizing a device that integrates the feeding, cutting, moving and welding functions in one, which can be suitable for binding the binding paper coil 90.
