[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0027] The spiral ring 1 in this utility model is made of plastic or rubber. The spiral ring 1 is a hollow cylindrical body 11 with open ends. The cylindrical body 11 has spiral grooves along the axial direction so that the cylindrical body 11 is spirally wound. The top and bottom ends of the spiral ring 1 are notched. The top end of the spiral ring 1 is an end head. The bottom end of the spiral ring 1 extends two opposing positioning extensions 12 on both sides of the notch, forming two closely spaced ends. The side of the loose-leaf 7 has mounting holes 8. Two mounting holes 8 are usually opened on one side of the loose-leaf 7. One spiral ring 1 is installed in each mounting hole 8 to bind the loose-leaf 7. The binding structure of this utility model is used to insert the spiral ring 1 into the mounting holes 8 of the loose-leaf 7. The specific structure includes a threading mandrel 2, a rolling wheel 3, and a needle-pulling group. The needle-pulling group includes a first needle 4, a second needle 5, and a third needle 6.

[0028] The threading mandrel 2 is a shaft 21, which is placed horizontally. The bottom end of the threading mandrel 2 can be slidably set on the platform. The spiral ring 1 is threaded on the top end of the threading mandrel 2. The process of threading the spiral ring 1 onto the threading mandrel 2 can be done manually or automatically by the threading mandrel 2 moving to the spiral ring 1 and using an auxiliary structure. The threading mandrel 2 is used to position the spiral ring 1 so that the spiral ring 1 can rotate around the threading mandrel.

[0029] The rubbing wheel 3 is rotatably connected to the platform. The rubbing wheel 3 can be rotated manually or automatically. The surface of the rubbing wheel abuts against the outer wall of the spiral ring 1 and forms static friction with the outer wall of the spiral ring 1. As the rubbing wheel 3 rotates, it drives the spiral ring 1 to rotate, so that the spiral ring 1 passes through and winds into the mounting hole 8 of the hinge 7.

[0030] In this embodiment, pin 1 4, pin 2 5 and pin 3 6 are three strip-shaped pieces of a certain length, all of which are arranged perpendicular to the axial direction of the spiral ring 1. Pin 1 4, pin 2 5 and pin 3 6 can all move independently.

[0031] like Figure 8 As shown, the threading mandrel 2 moves the spiral ring 1 between the loose-leaf 7 and the rubbing wheel 3. After the insertion pin 4 moves down, its bottom end is inserted into the gap 15 between the first coil 13 and the second coil 14 where the top of the spiral ring 1 is located, and pushes the first coil 13 axially away from the second coil 14, so that the top of the spiral ring 1 approaches and aligns with the mounting hole 8 of the loose-leaf 7. The top of the spiral ring 1 is inserted into the mounting hole 8 under the action of the rubbing wheel 3. At this time, the rubbing wheel continues to rotate, so that the spiral ring 1 gradually winds into the mounting hole 8. The rubbing wheel continues to rotate, and the two positioning extensions 12 at the tail end of the spiral ring 1 are offset from each other and located on one side of the loose-leaf 7. Since the two positioning extensions 12 need to be located on the upper and lower sides of the loose-leaf 7, At this point, both positioning extensions 12 are in a curved state and above the loose-leaf 7. Then, the insert pin 3 6 presses down, pressing one of the positioning extensions 12 at the tail end of the spiral ring 1 to the bottom of the loose-leaf 7. Next, the threading mandrel 2 retracts, separating the spiral ring 1 from the threading mandrel 2. The threading mandrel 2 then continues forward through the spiral ring 1, moving it a certain distance relative to the mounting hole 8 to adjust its position within the mounting hole 8. At this point, the other positioning extension 12 is above the mounting hole 8. Finally, the insert pin 2 5 presses down, pressing the positioning extension 12 into the mounting hole 8 and placing it at the bottom of the mounting hole 8. Thus, the spiral ring 1 is completely wound into the mounting hole 8, completing the binding of the loose-leaf 7. It should be noted that... Figure 8 The dotted square in the diagram represents pin 4, which is illustrated here.

[0032] It should be noted that the third pin 6 presses down the corresponding positioning extension 12 from one side of the threaded spindle 2, while the second pin 5 presses down the corresponding positioning extension 12 from the mounting hole 8. By controlling the degree of pressing down, the two positioning extensions 12 can be positioned at the bottom of the loose-leaf 7 or within the same page gap.

[0033] It should be noted that the spiral ring 1 can only form a closed loop and achieve complete binding when the two positioning extensions 12 are on the same page of the loose-leaf 7.

[0034] Specifically, the threading mandrel 2 includes a shaft body 21, and the surface of the shaft body 21 is provided with a limiting protrusion 22 for abutting against the tail end of the spiral ring 1, so that the spiral ring 1 is fitted and limited on the top of the shaft body 21, which facilitates the positioning of the spiral ring 1.

[0035] Furthermore, in this embodiment, the shaft 21 includes a first shaft segment 211 and a second shaft segment 212. The first shaft segment 211 is slidably connected to the frame, and the second shaft segment 212 is parallel to the binding edge of the loose-leaf 7. One end of the second shaft segment 212 is connected to the first shaft segment 211, and the other end serves as a suspended end to pass through the spiral ring 1. After passing through the second shaft segment 212, the spiral ring 1 is sleeved on the first shaft segment 211. The first shaft segment 211 is inclined relative to the second shaft segment 212 so that the first shaft segment 211 and the second shaft segment 212 together form an L-shaped shaft with an obtuse angle. In this way, the second shaft segment 212 is parallel to the straight vibration track 34, the first shaft segment 211 is inclined, and the spiral ring 1 is sleeved on the first shaft segment 211. If the spiral ring 1 is sleeved on the second shaft segment 212, the side of the loose-leaf 7 will interfere with the spiral ring 1 when the threading mandrel 2 advances to one side of the loose-leaf 7. However, the spiral ring 1 being sleeved on the first shaft segment 211 can avoid this situation.

[0036] Furthermore, the threading mandrel 2 is provided with a receiving groove 26 along the axial direction on the side facing the binding edge of the loose-leaf 7. The receiving groove 26 is used to wrap or accommodate the binding edge of the loose-leaf 7. That is, when the threading mandrel 2 moves to the binding edge of the loose-leaf 7 to prepare for binding, the receiving groove 26 just wraps or accommodates the binding edge, so that the mounting hole 8 is located within the radius of the threading mandrel 2, so that the spiral ring 1 can be smoothly inserted into the mounting hole 8.

[0037] Specifically, the pin-pulling assembly also includes a mounting base 9, a first drive group 10, a second drive group 16, and a third drive group 17. The mounting base 9 has vertical through holes, and pins 4, 5, and 6 are inserted into the corresponding through holes. The output ends of the first drive group 10, the second drive group 16, and the third drive group 17 are connected to the tops of pins 4, 5, and 6, respectively, thereby driving pins 4, 5, and 6 to move up and down along the through holes, thus pressing down the bottom ends of pins 4, 5, and 6. It should be noted that each of the three drive groups independently controls pins 4, 5, and 6, meaning they can operate independently.

[0038] In this embodiment, pin 1 4, pin 2 5 and pin 3 6 are three strip-shaped pieces of a certain length, all of which are arranged perpendicular to the axial direction of the spiral ring 1. Pin 1 4, pin 2 5 and pin 3 6 can move independently through the corresponding drive group.

[0039] Specifically, the mounting base 9 is provided with a horizontal groove 18, and a slider 19 is slidably connected in the groove 18. The mounting base 9 is also provided with a fourth drive group 20, which connects to the slider 19 and drives the slider 19 to move horizontally back and forth along the groove 18. The output end of the first drive group 10 is provided with a mounting block 23, and the mounting block 23 is provided with a horizontally inclined guide groove 24. The guide groove 24 gradually slopes downward along the forward direction of the spiral ring 1. The top end of the pin 4 is slidably connected in the guide groove 24, so that the pin 4 moves downward under the drive of the first drive group 10. At the same time, the pin 4 moves horizontally downward along the guide groove 24. Therefore, the continuous action of the bottom end of the pin 4 being pressed down and then pushed is realized. That is, the pin 4 is first pressed down and inserted into the gap 15 between the first turn 13 and the second turn 14, and then moves horizontally along the guide groove 24 to push the first turn 13 of the spiral ring 1.

[0040] It should be noted that after the first rotation 13 is pushed by the first pin 4, it forms a certain limit on the spiral ring 1. At this time, the rubbing wheel 3 rotates to provide rotational power, so that the spiral ring 1 rotates forward in one direction. If there is no limit from the first pin 4, the spiral ring 1 will only rotate in place and will not move forward under the drive of the rubbing wheel 3, or it will rotate randomly and then break away from the rubbing wheel.

[0041] Furthermore, the insert pin 4 includes a vertically arranged needle body 41. The top of the needle body 41 is connected to the guide groove 24, and the bottom end of the needle body 41 serves as an insertion end 43. The insertion end 43 is inserted into the gap 15 between the first turn 13 and the second turn 14 of the spiral ring 1 and pushes the first turn 13. The insertion end 43 approaches or abuts against the outer wall of the spiral ring 1, thereby ensuring the operation of the insert pin 4.

[0042] It should be noted that the bottom end of the needle body 41 can also be made into an inclined surface. The inclined surface serves as an auxiliary part and plays a certain role in stabilizing the spiral ring 1 during rotation. If there is no inclined surface, the insertion end 43 can also work independently.

[0043] It should be noted that the guide groove and slide 18 mentioned above are only one driving method to realize the up and down movement of the pin. Other driving methods can also be used, which will not be elaborated here.

[0044] Specifically, the table surface is provided with a positioning block 25 for positioning the loose-leaf 7, and a pressing block is also provided on the table surface. The pressing block is driven by a driving mechanism to press down onto the surface of the loose-leaf 7, thereby positioning the loose-leaf 7 to ensure the binding work.

[0045] The first drive group 10, the second drive group 16, the third drive group 17 and the fourth drive group 20 mentioned above can be electrically, hydraulically or pneumatically driven.

[0046] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
