[0051] The frame includes a top plate 1, an upper support rod 2, a lower support rod 3, and a base 4. The workbench 5 is installed in the middle of the frame. The upper support rod 2 is fixedly connected between the top plate 1 and the workbench 5, and the lower support rod 3 is fixedly connected between the workbench 5 and the base 4. A paper pressing device, an upper riveting device, an automatic tube cutting device, and a tube receiving device are installed between the top plate 1 and the workbench 5. An automatic punching device and a lower riveting device are installed between the workbench 5 and the base 4.

[0052] like Figures 3 to 6 As shown, the riveting head device includes an upper lifting device, a first mounting base 6, and an upper riveting head 7. The upper lifting device includes a first driver 8 and a first lead screw 9. A first guide post 10 is fixedly connected between the top plate 1 and the worktable 5. The first mounting base 6 is provided with a first guide hole 601 that matches the first guide post 10 and a first nut 602 that matches the first lead screw 9. The first mounting base is fitted over the first guide post 10 and the first lead screw 9, and the first nut 602 is screwed onto the first lead screw 9. The first driver 8 is fixedly mounted on the upper surface of the top plate 1. The first driver 8 is connected to the first lead screw 9 and can drive the first lead screw 9 to rotate, thereby enabling the first mounting base 6 to move up and down along the first lead screw 9.

[0053] The lower side of the front end of the first mounting base 6 is provided with an upper riveting head 7. For ease of explanation, when binding paper, the side of the binding machine closer to the person is the front end, and the side farther away from the person is the rear end.

The two opposite side walls of the upper riveting head 7 are respectively provided with a first cleaning hole 702 and a second cleaning hole 703. In this specific embodiment, the first cleaning hole 702 is provided on the front side wall of the upper riveting head 7, and the second cleaning hole 703 is provided on the rear side wall of the upper riveting head 7. This arrangement is more convenient to use. A light-transmitting hole 603 is provided at the position where the first mounting base 6 connects to the upper riveting head 7, and the light-transmitting hole 603 communicates with the riveting head hole 701. A mounting boss 101 is provided on the front side of the top plate 1, above the light-transmitting hole 603. A mounting groove 102 is provided on the upper side of the mounting boss 101, and a mounting hole 103 is provided at the bottom of the mounting groove 102. The mounting hole 103 is located above the light-transmitting hole 603 of the first mounting base 6. A first photoelectric sensor 11 is installed in the mounting groove 102. The detection part of the first photoelectric sensor 11 extends into the mounting hole 103. The light emitted by the first photoelectric sensor 11 can pass through the light-transmitting hole 603 and the rivet hole 701. If there is a foreign object in the rivet hole 701, the light emitted by the first photoelectric sensor 11 cannot pass through the rivet hole 701, and the first photoelectric sensor 11 can generate a detection signal. Therefore, the first photoelectric sensor 11 can detect whether there is a foreign object in the rivet hole 701.

[0054] When the riveting head device is working, the first driver 8 is activated, and the first driver 8 drives the first lead screw 9 to rotate, which can drive the first mounting base 6 to move up and down. When the first mounting base 6 moves down to the set position, the riveting head 7 can rivet the upper end of the riveting tube in the paper binding hole on the worktable 5.

[0055] like Figures 7 to 9 As shown, the lower riveting head device includes a lower lifting device, a second mounting base 12, and a lower riveting head 13.

A fourth guide hole 604 matching the second guide post 14 is provided on the first mounting base 6. The first mounting base 6 is also fitted outside the second guide post 14 and the first mounting base 6 slides with the second guide post 14.

[0056] The lowering and lifting device includes a second driver 17 and a second lead screw 16. The second guide column 14 and the second lead screw 16 are connected by a connector 18. One end of the connector 18 is fixedly connected to the lower end of the second guide column 14, and the lower end of the second lead screw 16 is fixedly connected to the other end of the connector 18. The second driver 17 is mounted on the second mounting base 12, and a second gear is mounted on the output end of the second driver 17. A second nut 1201 is rotatably connected to the second mounting base 12. A bearing 1202 is provided on the second mounting base 12, and the outer ring of the bearing 1202 is fixedly connected to the second mounting base 12. The second nut 1201 has a protruding neck 1203, which fits within the inner ring of the bearing 1202. A first gear is provided on the outer peripheral wall of the second nut 1201, which is exposed outside the bearing 1202, and the first gear meshes with the second gear. The second driver 17 can drive the second nut 1201 to rotate, thereby causing the second mounting base 12 to move up and down outside the lead screw.

[0057] The lower riveting head 13 is fixedly connected to the second mounting base 12, and a centering pin 19 is provided in the middle of the upper end face of the lower riveting head 13. The worktable 5 is provided with a riveting position, and the riveting position has a through hole 501. The lower riveting head 13 can pass through the through hole 501 to rivet the lower end of the rivet tube on the paper. The centering pin 19 is coaxial with the riveting hole 701 of the upper riveting head 7, and the centering pin 19 can be inserted into the riveting hole 701. The automatic punching device includes a punching knife 20, which is disposed on the second mounting base 12; the second guide post 14 can rotate in both directions to alternately align the lower riveting head 13 and the punching knife 20 with the through hole 501 of the riveting position.

[0058] The base 4 is fixedly connected to the first slide rail 21 and the second slide rail 22 on both sides, and the upper ends of the first slide rail 21 and the second slide rail 22 are both fixedly connected to the lower surfaces of both sides of the workbench 5. The lower end of the front sidewall of the first slide rail 21 is provided with a first groove 2101, and the lower end of the front sidewall of the second slide rail 22 is provided with a second groove 2201. The second mounting base 12 is provided with a first slider 23 on the side near the punch 20. The first slider 23 is roller-shaped and rotatably connected to the second mounting base 12. The second mounting base 12 is provided with a second slider 24 on the side near the lower rivet head 13. The second slider 24 is also roller-shaped and rotatably connected to the second mounting base 12. When the lower rivet head 13 is aligned with the through hole 501, the first slider 23 slides within the first slide rail 21, that is, the first slider 23 can roll along the sidewall of the first slide rail 21. When the punch 20 is aligned with the through hole 501, the second slider 24 slides within the second slide rail 22, meaning the second slider 24 can roll along the side wall of the second slide rail 22.

[0059] When punching is required, the second guide post 14 is rotated, aligning the punching blade 20 with the through hole 501. At this time, the second slider 24, within the second slide rail 22, activates the second driver 17, causing the second mounting base 12 to move upward. Once the punching blade 20 passes through the through hole 501, it can punch holes in the paper on the workbench 5. After punching, the second driver 17 controls the second mounting base 12 to move downward. When it reaches the set position, the second guide post 14 is rotated, aligning the lower rivet head 13 with the through hole 501. At this time, the second slider 24, within the second slide rail 22, activates the second driver 17, causing the second mounting base 12 to move upward. During the upward movement of the second mounting base 12, the centering pin 19 first passes through the through hole 501, then through the binding hole of the paper, and inserts into the rivet head hole 701 of the upper rivet head 7. The lower rivet head 13 then contacts the rivet tube inside the binding hole of the paper, allowing it to rivet the lower end of the rivet tube.

The rope 28 presses against the lower side of the crossbar of the support member 32, and the crossbar of the limiting member 39 supports the upper side of the rope 28.

[0065] The aforementioned pipe support assembly includes a connecting post 40 and a pipe support 41. A mounting base 43 is provided on the worktable 5, and a hollow guide tube is provided on the mounting base 43. A guide through hole 42 is provided on the worktable 5, and the guide tube is aligned with the guide through hole 42. The connecting post 40 is slidably fitted within the guide tube, and the lower end of the connecting post 40 is exposed on the lower side of the worktable 5.

[0066] The automatic pipe cutting device includes a pipe cutting blade 44 and a pushing device 45. The mounting base 43 has a sliding groove 4301, in which the pipe cutting blade 44 is slidably fitted. The bottom of the sliding groove 4301 has a rivet hole 4302, which is aligned with the pipe drop hole 502. The pushing device 45 is mounted on the connecting base and can push the pipe cutting blade 44 to cut off the rivet standing in the rivet hole 4302.

The pipe support 41 is located below the pipe drop hole 502 of the worktable 5, and has a notch 4101 directly below the pipe drop hole 502, allowing a guide needle to pass through.

[0067] Before cutting the rivet tube, the swing arm 31 of the take-up and release assembly swings towards the second through hole 38501. At this time, the distance between the end of the swing arm 31 and the first through hole 37501 is lengthened, and a portion of the rope 28 is taken back by the take-up and release assembly. After the paper pressing table 25 presses down the paper to be bound and the rivet tube is cut, the swing arm 31 of the take-up and release assembly swings towards the first channel again, reducing the distance between the end of the swing arm 31 and the first through hole 37501. The previously taken-back rope 28 is lowered towards the side of the connecting tube support assembly, thereby allowing the connecting tube support 41 to be lowered and eliminating the interference problem of the worktable 5.

[0068] The fully automatic hot riveting binding machine disclosed in this application operates as follows: First, the paper to be bound is placed on the worktable 5; the paper pressing table 25 moves down to press the paper. During the downward movement of the paper pressing table 25, the connecting tube support 41 also moves upward under the action of the rope 28, allowing adjustment of the riveting tube height. This process determines the cutting length of the riveting tube based on the paper thickness. During the upward movement of the connecting tube support 41, the punching knife 20 aligns with the through hole 501, at which point the lower riveting head 13 is located below the connecting tube support 41. The upward movement of the second mounting base 12 causes the punching knife 20 and the lower riveting head 13 to move upward, punching a hole in the paper, and the centering needle 19 on the lower riveting head 13 inserts into the riveting tube. Simultaneously, the tube cutting knife 44 cuts off the riveting tube, and the retracting assembly lowers the connecting tube support 41 to the set position. At this point, the cut riveting tube is fitted onto the centering needle 19. The second guide column 14 is rotated to align the lower riveting head 13 on the second mounting base 12 with the through hole 501. Then, the upper riveting head 7 moves upward and downward. The end of the centering pin 19 of the upper riveting head 7 passes through the through hole 501 and the binding hole of the paper, and is then inserted into the riveting hole 701 of the upper riveting head 7. After this process has been going on for a certain period of time, the rivet tube is inserted into the binding hole of the paper, and the upper riveting head 7 and the lower riveting head 13 simultaneously rivet the upper and lower ends of the rivet tube to complete the binding process.
