The manual wire binding method is to use a wire awl to punch three binding holes in the file and then use a crochet hook to pass through the binding holes one by one to hook the binding wire, and finally manually tie a knot for binding. A large amount of labor is required for punching holes, hooking wires, and tying knots during the binding process, resulting in high labor costs and low production efficiency, and bringing great inconvenience to production.

[0064] The beneficial effects of the present invention are as follows:

[0065] The three-hole wire binding machine of the present invention can replace the existing manual binding, realize automatic punching, wire hooking, and knotting, improve production efficiency, and reduce labor costs. Among them, the conveying mechanism can respectively convey the files to be bound to the working positions of the drilling mechanism and the wire hooking and separating mechanism. The drilling mechanism can drill three binding holes on the file that are located on the same straight line. The wire feeding mechanism can convey the binding thread to the lower part of the wire hooking and separating mechanism. The wire hooking and separating mechanism can respectively hook out the binding thread from the three binding holes and separate the binding thread hooked out from the middle hole to form a wire hole. The two threading mechanisms can perform the first knotting. Specifically, one threading mechanism clamps the binding thread hooked out from the left end hole and passes it through the wire hole, and the other threading mechanism clamps the binding thread hooked out from the right end hole and passes it through the wire hole to realize the first knotting. Then, the knotting mechanism knots the binding threads on both sides to realize the second knotting.

[0066] When the wire pulling mechanism in the wire feeding mechanism of the present invention operates, the wire pulling mechanism drives the wire pulling chuck to move. After the wire pulling chuck is opened through the chuck opening mechanism, it clamps the binding thread on the wire bearing mechanism. The wire pulling mechanism runs in the reverse direction to realize automatic wire feeding. Among them, the hook needle positioning mechanism is located directly below the binding hole of the file. When the bottom of the hook needle penetrates through the binding hole of the file and is inserted into the hook needle slot of the positioning pin, under the action of the pressure applied by the hook needle, the positioning pin moves downward within the inner hole of the upper positioning sleeve, the positioning through hole of the positioning seat body, and the inner hole of the lower positioning sleeve. The binding thread tensioned on the positioning pin slides into the groove of the hook needle, thereby hooking the binding thread and increasing the success rate of the hook needle hooking the wire.

[0067] When the thread - hooking and thread - separating mechanism of the present invention operates, the thread - hooking motor drives the right thread - hooking gear, the transmission shaft and the left thread - hooking gear to rotate together, thereby driving the right thread - hooking rack and the left thread - hooking rack to move downward. The right thread - hooking rack and the left thread - hooking rack drive the left needle mechanism, the needle - separating mechanism and the right needle mechanism on the thread - hooking intermediate plate to move downward. The grooves at the bottoms of the left needle mechanism, the needle - separating mechanism and the right needle mechanism respectively penetrate through the three binding holes on the file and then hook the binding thread located directly below the three binding holes. After the left needle mechanism, the needle - separating mechanism and the right needle mechanism hook the binding thread, the thread - hooking motor runs in the reverse direction, driving the left needle mechanism, the needle - separating mechanism and the right needle mechanism to move upward. When the top of the separating rack of the needle - separating mechanism touches the thread - hooking top plate, the separating rack in the needle - separating mechanism moves downward, driving the half - teeth of the left half - needle to rotate, and the half - teeth of the right half - needle also rotate simultaneously. After the left half - needle and the right half - needle are separated, the binding thread obtained by the needle - separating mechanism forms a thread hole. In the whole process, the needles penetrate through the three binding holes on the file, and the operations of thread - hooking and thread - separating are all automated, which can replace the existing manual thread - hooking and thread - separating methods, saving time and effort, reducing the visual fatigue caused by the manual thread - hooking and thread - separating method, and improving production efficiency.

[0068] When the clamping motor of the thread - threading mechanism of the present invention works, it drives the clamping gear to rotate, thereby causing the clamping rack to drive the clamping sleeve and the clamping shaft to move back and forth. The thread - threading mechanism has the function of clamping the binding thread and driving the binding thread to move. It can be used in a three - hole wire - type binding machine or other equipment. The clamping bracket is elastically arranged on the support plate. When the clamping jaws 1 and 2 clamp and tighten the binding thread, after the binding thread is tightened, under the action of the tension spring, the clamping bracket will move on the support plate to prevent the binding thread from being broken due to excessive tightness. Therefore, due to the action of the tension spring, the binding thread has a certain degree of tightness. There are two thread - threading mechanisms. One thread - threading mechanism can clamp the binding thread hooked out from the left - end hole of the file and make it pass through the thread hole, and the other thread - threading mechanism can clamp the binding thread hooked out from the right - end hole of the file and make it pass through the thread hole. The two thread - threading mechanisms jointly tighten the left line segment and the right line segment to achieve the preliminary knotting operation. After the thread - threading mechanism achieves the preliminary knotting, the knotting mechanism starts to perform the secondary knotting, replacing manual knotting, reducing the knotting workload of the staff, and improving the overall work efficiency.

[0121] The following further describes the detailed implementation manners of the present invention with reference to the drawings:

[0122] A three-hole wire binding machine belongs to a three-hole one-line file binding machine. As Figures 1 - 3 shown, it includes a frame body 1 and a conveying mechanism 2, a drilling mechanism 3, a hook wire and wire splitting mechanism 4, a knotting mechanism 5, a threading mechanism 6, a wire feeding mechanism 7 and a control device 10 provided on the frame body 1.

[0123] As Figures 1 - 3 shown, the conveying mechanism 2 is located below the drilling mechanism 3 and the hook wire and wire splitting mechanism 4. The conveying mechanism 2 is used to convey the file to be bound to the working positions of the drilling mechanism 3 and the hook wire and wire splitting mechanism 4. The drilling mechanism 3 is located in front of the hook wire and wire splitting mechanism 4. The drilling mechanism 3 is used to drill three binding holes on the file that are located on the same straight line. The three binding holes are sequentially recorded as the left end hole, the middle hole and the right end hole from left to right. The drilling mechanism 3 in this embodiment adopts an existing drilling mechanism and has a built-in pressing plate, which can press the file and then drill the file. The wire feeding mechanism 7 is located below the hook wire and wire splitting mechanism 4. The wire feeding mechanism 7 is used to convey the binding wire 11 to the lower part of the hook wire and wire splitting mechanism 4. The hook wire and wire splitting mechanism 4 is used to hook out the binding wire 11 from the three binding holes respectively and separate the binding wire 11 hooked out from the middle hole to form as Figure 14The wire hole 14 shown. There are two threading mechanisms 6, which are respectively located on both sides of the thread-hooking and thread-splitting mechanism 4 and are installed on the support plate 9. The installation positions of the two threading mechanisms 6 are as Figure 4 shown. The two threading mechanisms 6 are used for the first knotting. Specifically, one threading mechanism 6 is used to clamp the binding thread 11 hooked out from the left end hole and make it pass through the wire hole 14, and the other threading mechanism 6 is used to clamp the binding thread 11 hooked out from the right end hole and make it pass through the wire hole 14. Figure 4 In it, e represents the position where the binding thread 11 hooked out from the left end hole by the left hook needle mechanism 4A is located, f represents the position where the binding thread 11 hooked out from the right end hole by the right hook needle mechanism 4B is located, and g represents the position where the left half hook needle 4C5 and the right half hook needle 4C6 are located after hooking out and separating the binding thread 11 from the middle hole. The state after passing through the wire hole 14 and tightening the binding threads 11 on both sides is as Figure 36 shown. Then, the knotting mechanism 5 performs secondary knotting. Specifically, the knotting mechanism 5 is located at the rear lower part of the thread-hooking and thread-splitting mechanism 4 and is used for knotting the binding threads 11 on both sides. The knotting sequence is as Figure 34 shown.

[0124] Among them, the conveying mechanism 2, the drilling mechanism 3, the thread-hooking and thread-splitting mechanism 4, the knotting mechanism 5, the threading mechanism 6, and the wire-feeding mechanism 7 are all electrically connected to the control device 10. The control device 10 is used to control the operation of each mechanism respectively. The conveying mechanism 2, the drilling mechanism 3, the thread-hooking and thread-splitting mechanism 4, the knotting mechanism 5, the threading mechanism 6, the wire-feeding mechanism 7, and the control device 10 are all electrically connected to an external power source.

[0125] In this embodiment, as Figures 5 - 8 shown, the conveying mechanism 2 includes a pallet 202, a guide rod 203, a conveying compression spring 204, a conveying lead screw 205, a conveying push plate 206, a box body 207, a first connecting plate 208, a folding lifting bracket, a conveying motor 216, a conveying guide rail 209, a Z-shaped fixing bracket 210, a conveying top plate 211, and a bottom plate 8;

[0126] The bottom plate 8 is fixedly connected to the frame body 1 by screws. The fixing frame 210 and the first connecting plate 208 are both fixedly connected to the bottom plate 8 by screws. The conveying motor 216 is arranged on the fixing frame 210. The output shaft of the conveying motor 216 is key-connected to the rear end of the conveying lead screw 205. The front end of the conveying lead screw 205 is rotatably connected to the first connecting plate 208 through a bearing 13. A nut is threadedly connected to the conveying lead screw 205, and the nut is fixedly connected to the front end plate 201. The front end plate 201 is slidably connected to the front end of the guide rod 203. The conveying push plate 206 is fixedly connected to the rear end of the guide rod 203. A conveying compression spring 204 is sleeved on the guide rod 203 and the conveying compression spring 204 is located between the front end plate 201 and the conveying push plate 206. The bottom of the folding lifting bracket is rotatably connected to the fixing frame 210. The top of the folding lifting bracket is rotatably connected to a conveying top plate 211 and the conveying top plate 211 is located below between the two conveying guide rails 209. The two conveying guide rails 209 are fixedly connected to the upper part of the bottom plate 8 in parallel by screws and brackets. The conveying guide rails 209 are parallel to the conveying lead screw 205. The top of the front end plate 201 is connected to a box body 207. The box body 207 is slidably connected to the conveying guide rails 209. A tray 202 for placing files is placed in the box body 207. A conveying pressure plate 217 is connected above the rear end of the conveying guide rails 209.

[0127] The conveying motor 216 is used to drive the conveying lead screw 205 to rotate, thereby driving the nut, the front end plate 201, the guide rod 203, the conveying compression spring 204 and the conveying push plate 206 to move horizontally in a straight line back and forth together, and finally driving the box body 207 to move back and forth along the conveying guide rails 209. As Figures 5 - 7As shown, the pallet 202 is located inside the box body 207. Archives to be bound are placed on the pallet 202, and the pallet 202 moves back and forth together with the box body 207. The pallet 202 is provided with three slide plate holes 2022. Slide plates 2021 are elastically connected inside the three slide plate holes 2022 through compression springs respectively. The outer surface of the slide plate 2021 is wrapped with an insulating layer and is in insulating sliding connection with the pallet 202, that is, in insulating connection with the frame body 1. The slide plate 2021 can move linearly in the slide plate holes 2022 of the pallet 202 under the push of an external force. The circular conductive rubber pad 2025 is installed on the slide plate 2021. There is a wire on the drilling motor in the drilling mechanism 3 connected to the frame body 1, and there is also a wire on the slide plate 2021 connected to the main board in the control device 10. When the drill bit on the drilling motor of the drilling mechanism 3 penetrates through the archives to form three binding holes and hits the conductive rubber pad 2025 below the archives, at the moment when the drill bit contacts the conductive rubber pad 2025, an electrical signal path is formed between the slide plate 2021 and the frame body 1 (the slide plate 2021 and the frame body 1 are made of conductive materials). The slide plate 2021 transmits the path signal to the main board, indicating that the punching is completed. The main board controls the drilling motor in the drilling mechanism 3 to perform the next action. The conveying motor 216 drives the box body 207 and the pallet 202 to move backward along the conveying guide rail 209 (i.e., in the direction where the conveying motor 216 is located) under the control of the control device 10. When moving below the drilling mechanism 3, the conveying motor 216 stops running, and the drilling mechanism 3 starts to work for punching. After the punching is completed, the drilling mechanism 3 resets, and the conveying motor 216 continues to run, driving the box body 207 and the pallet 202 to continue moving backward along the conveying guide rail 209. The conveying top plate 211 is provided with raised retaining strips (not shown in the figure). When the box body 207 and the pallet 202 move backward above the conveying top plate 211, when the screw blocking blocks 2024 provided at the bottoms of the three slide plates 2021 on the pallet 202 jointly touch the retaining strips provided on the upper surface of the conveying top plate 211, the three slide plates 2021 stop moving backward, while the box body 207, the pallet 202, and the archives continue to move backward under the drive of the conveying motor 216, so that the slide plate 2021 moves in the opposite direction (i.e., forward) in the slide plate holes 2022 of the pallet 202. The slide plate 2021 avoids the already punched binding holes on the archives, and a through hole 2023 is formed in the slide plate holes 2022 directly below the already punched binding holes on the archives, thus facilitating the hook wire and wire separating mechanism 4 to hook the binding wires located below the pallet 202. When the conveying push plate 206 touches the folding and raising bracket, such as Figure 8As shown, the folding lifting bracket starts to rise, thereby driving the conveying top plate 211 to rise. When the conveying top plate 211 rises, it just pushes up the support plate 202 in the box body 207. After the support plate 202 drives the file to rise, the top of the file presses against the conveying pressure plate 217, and the conveying push plate 206 stops moving backward. The conveying pressure plate 217 is provided with a hook hole 2171. When the hook and line dividing mechanism 4 is working, the left hook mechanism 4A, the hook and line dividing mechanism 4C and the right hook mechanism 4B move downwards and pass through the following in sequence: Figure 4 The hook and line separation mechanism through hole 903 on the support plate 9 shown in FIG. Figure 7 The hook hole 2171 of the conveying plate 217 shown in the figure, the three binding holes on the file, Figure 8 The slide plate 2021 shown in the figure avoids the through hole 2023 formed in the slide plate hole 2022 of the support plate 202 and then hooks the binding line. The conveying pressing plate 217 is located below the hooking and dividing line mechanism 4, and the wire feeding mechanism 7 is located below the conveying pressing plate 217.

[0128] In this embodiment, the folding and lifting bracket includes two pairs of connecting rod mechanisms, which are arranged in parallel. The tops of the two pairs of connecting rod mechanisms are rotatably connected to the conveying top plate 211 through the connecting rod seat 218, and the bottoms of the two pairs of connecting rod mechanisms are rotatably connected to the fixing frame 210 through the connecting rod seat 218. Figures 5 - 6 As shown, the connecting rod mechanism includes two upper connecting rods 212, two lower connecting rods 213 and a transverse connecting rod 214, the two upper connecting rods 212 are arranged in parallel front and back, and the top ends of the two upper connecting rods 212 are rotatably connected to the conveying top plate 211 through a connecting rod seat 218, the two lower connecting rods 213 are arranged in parallel front and back, and the bottom ends of the two lower connecting rods 213 are rotatably connected to the fixed frame 210 through a connecting rod seat 218, the bottom end of an upper connecting rod 212, the top end of a lower connecting rod 213 and one end of the transverse connecting rod 214 are rotatably connected through a connecting rod cylindrical pin 219 and a bearing 13, and the bottom end of another upper connecting rod 212, the top end of another lower connecting rod 213 and the other end of the transverse connecting rod 214 are rotatably connected through a connecting rod cylindrical pin 219 and a bearing 13.

[0129] like Figure 5 As shown, the fixed frame 210 is a Z-shaped frame, and a conveying slide 220 is fixedly connected to the bottom of the conveying top plate 211, and the side of the conveying slide 220 is in vertical rolling contact with the fixed frame 210 through the bearing 13. When the folding and lifting bracket is raised or lowered, the conveying slide 220 rolls on the vertical plate in the fixed frame 210.

[0130] In this embodiment, the conveying motor 216 is fixedly connected to the connecting seat 215 by screws 12, the connecting seat 215 is fixedly connected to the fixing frame 210 by screws 12, the output shaft of the conveying motor 216 is connected to the rear end of the conveying lead screw 205 by a key, and the rear end of the conveying lead screw 205 is rotatably connected to the connecting seat 215 by a bearing 13. The connecting seat 215 ensures the structural stability.

[0131] In this embodiment, as Figure 9 and Figure 10 shown, the wire feeding mechanism 7 includes a wire tensioning wheel 7A, a second connecting plate 701, a wire supporting mechanism 7B, a clamping mechanism 7C, a hook needle positioning mechanism 7D, a wire routing mechanism 7E, and a wire pulling mechanism 7F. Figure 2 The enlarged view of the wire feeding mechanism 7 in Figure 9 is shown as

[0132] As Figure 9 and Figure 10 shown, the wire tensioning wheel 7A is arranged at the left end of the bottom plate 8, the wire pulling mechanism 7F is arranged at the right end of the bottom plate 8, the second connecting plate 701 is connected to the bottom plate 8 by equal-height columns and screws 12 and is located above the bottom plate 8, and the second connecting plate 701 is located between the wire tensioning wheel 7A and the wire pulling mechanism 7F.

[0133] As Figure 12 in (a) of Figure 12 and Figure 9 in (b) of

[0134] shown, the wire tensioning wheel 7A includes a wire tensioning connection block 7A1, a wire tensioning shaft 7A2, a wire tensioning pressing plate 7A3, a wire tensioning compression spring 7A4, and a wire tensioning nut 7A5. The wire tensioning connection block 7A1 is fixedly connected to the bottom plate 8 by screws 12, the wire tensioning shaft 7A2 is connected to the wire tensioning connection block 7A1, the wire tensioning nut 7A5 is threadedly connected to the wire tensioning shaft 7A2, the wire tensioning pressing plate 7A3 is sleeved on the wire tensioning shaft 7A2, one end of the wire tensioning compression spring 7A4 is connected to the wire tensioning nut 7A5, and the other end is connected to the wire tensioning pressing plate 7A3. As Figure 9 shown, the binding wire 11 is wound around the winding cylinder, and after passing through between the wire tensioning pressing plate 7A3 and the wire tensioning connection block 7A1, it passes through the wire supporting mechanism 7B. The wire tensioning pressing plate 7A3 has a certain pressing effect on the binding wire 11 under the action of the wire tensioning compression spring 7A4 to achieve the wire tensioning effect.

[0134] The wire pulling mechanism 7F includes a wire pulling chuck and a chuck driving mechanism for driving the wire pulling chuck to move linearly.

[0135] As Figure 13 in (a) of Figure 13 and Figure 13As shown in (c) thereof, the collet driving mechanism includes a wire-pulling rack 7F4, a wire-pulling motor 7F2 and a wire-pulling gear 7F3. The wire-pulling motor 7F2 is fixedly connected to the bottom plate 8 through a wire-pulling seat body 7F1 and a screw 12. A wire-pulling through groove for accommodating the wire-pulling rack 7F4 is provided in the wire-pulling seat body 7F1. The wire-pulling rack 7F4 is located in the wire-pulling through groove and can slide in the wire-pulling through groove. The output shaft of the wire-pulling motor 7F2 is connected with a wire-pulling gear 7F3. The wire-pulling gear 7F3 meshes with the wire-pulling rack 7F4. One end of the wire-pulling rack 7F4 is connected with a wire-pulling collet. The wire-pulling collet includes an upper wire-pulling collet 7F6 and a lower wire-pulling collet 7F7. The lower wire-pulling collet 7F7 is fixedly connected with one end of the wire-pulling rack 7F4. The upper wire-pulling collet 7F6 is rotationally connected with the lower wire-pulling collet 7F7 through a wire-pulling pin. A wire-pulling compression spring 7F5 is arranged between the upper wire-pulling collet 7F6 and the lower wire-pulling collet 7F7. When the wire-pulling compression spring 7F5 is in a natural state, the upper wire-pulling collet 7F6 and the lower wire-pulling collet 7F7 are in close contact. Under the action of an external force, the upper wire-pulling collet 7F6 and the lower wire-pulling collet 7F7 can be separated. When the wire-pulling motor 7F2 operates, the wire-pulling motor 7F2 drives the wire-pulling gear 7F3 to rotate, and the wire-pulling gear 7F3 drives the wire-pulling rack 7F4 and the wire-pulling collet to move horizontally.

[0136] As Figure 10 shown, the wire-bearing mechanism 7B is fixedly connected to the second connecting plate 701 through a screw 12. Two square first through grooves 7012 for the clamping mechanism 7C to pass through and rotate, three circular second through grooves 7013 for the crochet positioning mechanism 7D to pass through, and six strip-shaped sliding grooves 7011 for the wiring posts 7E1 to pass through and move linearly are formed in the second connecting plate 701.

[0137] As Figure 14 in (a) and Figure 14As shown in (b) thereof, the wire receiving mechanism 7B includes a wire receiving connection block 7B1, a wire receiving sleeve 7B5, a wire receiving pipe 7B4 and a wire receiving compression spring 7B3. The outer part of the wire receiving pipe 7B4 is fixedly connected with the wire receiving sleeve 7B5. The wire receiving sleeve 7B5 is sleeved with the wire receiving connection block 7B1 on the outside, and the wire receiving sleeve 7B5 and the wire receiving connection block 7B1 are slidably and elastically connected through the wire receiving compression spring 7B3. A wire receiving retaining ring 7B2 is connected to the outer surface of the wire receiving sleeve 7B5. And in the natural state of the wire receiving compression spring 7B3, the wire receiving retaining ring 7B2 contacts the left end of the wire receiving connection block 7B1. The wire receiving connection block 7B1 is fixedly connected with the second connecting plate 701 through a screw 12. The binding wire 11 passes through the wire receiving pipe 7B4 and slightly exposes from one end of the wire receiving pipe 7B4. When the wire clamping head passes through the clip opening mechanism 7C, the upper wire clamping head 7F6 and the lower wire clamping head 7F7 in the wire clamping head are separated. Immediately afterwards, the separated upper wire clamping head 7F6 and the lower wire clamping head 7F7 touch the right end of the wire receiving sleeve 7B5. The wire receiving sleeve 7B5 and the wire receiving pipe 7B4 move leftward. When the upper wire clamping head 7F6 and the lower wire clamping head 7F7 are closed under the action of the wire pulling compression spring 7F5, they just clamp the binding wire 11 at the end of the wire receiving sleeve 7B5.

[0138] There are two clip opening mechanisms 7C, and the clip opening mechanism 7C is used to separate the upper wire clamping head 7F6 and the lower wire clamping head 7F7 in the wire clamping head; as Figure 10 shown, one clip opening mechanism 7C is located on the right side of the wire receiving mechanism 7B, and the other clip opening mechanism 7C is located on the left side of the wire pulling mechanism 7F. The clip opening mechanism 7C is connected to the bottom plate 8, and the top end of the clip opening mechanism 7C passes through the first through groove 7012 on the second connecting plate 701.

[0139] As Figure 15 in (a), Figure 15 in (b) and Figure 15As shown in (c) thereof, the clip-opening mechanism 7C includes a clip-opening seat 7C1, a clip-opening pin 7C2 and a clip-opening block 7C3. A through hole for mounting the clip-opening seat 7C1 is provided on the base plate 8. The clip-opening seat 7C1 is fixedly connected to the through hole of the base plate 8 by screws 12. There is a certain gap below the through hole of the base plate 8 to facilitate the rightward rotation of the clip-opening block 7C3. The clip-opening seat 7C1 is rotationally connected to the clip-opening block 7C3 through the clip-opening pin 7C2. A clip-opening stop block 7C11 for preventing the clip-opening block 7C3 from rotating to the left is provided on the clip-opening seat 7C1. The clip-opening stop block 7C11 is located above the clip-opening pin 7C2. A square groove 7C31 is provided at the top position of the clip-opening block 7C3. Two slope blocks 7C5 are provided at the top end of the clip-opening block 7C3 and the two slope blocks 7C5 are located on both sides of the square groove 7C31. The upper surface of the slope block 7C5 is composed of a slope surface 7C51 and a horizontal surface 7C52. The distance between the two slope blocks 7C5 is less than the width of the square groove 7C31. When the wire-pulling chuck passes through the clip-opening mechanism 7C, the lower wire-pulling chuck 7F7 passes through the square groove 7C31, while the upper wire-pulling chuck 7F6 just touches the two slope blocks 7C5. A guiding inclined surface is also provided at the front end of the surface of the upper wire-pulling chuck 7F6 facing the lower wire-pulling chuck 7F7. Under the guiding action of the guiding inclined surface, the upper wire-pulling chuck 7F6 moves along the slope surface 7C51 of the slope block 7C5. Finally, the upper wire-pulling chuck 7F6 passes through above the slope block 7C5, and the upper wire-pulling chuck 7F6 is separated from the lower wire-pulling chuck 7F7, that is, the wire-pulling chuck is opened.

[0140] As Figures 16 - 17 shown, the wiring mechanism 7E includes a wiring driving mechanism, a wiring connecting plate 7E2 and six wiring posts 7E1. The wiring driving mechanism is connected to the base plate 8. Six wiring posts 7E1 are fixedly connected to the wiring connecting plate 7E2. The wiring connecting plate 7E2 is located below the second connecting plate 701, and the tops of the six wiring posts 7E1 thereon respectively pass through six strip-shaped sliding grooves 7011 on the second connecting plate 701. The wiring driving mechanism is connected to the wiring connecting plate 7E2 and is used to drive the wiring connecting plate 7E2 to move linearly, thereby driving the plurality of wiring posts 7E1 to move linearly along the strip-shaped sliding grooves 7011. Wiring posts 7E1 are provided on both the left and right sides of the three hook needle positioning mechanisms 7D. The initial position of the wiring posts 7E1 is located on the front side of the wire-receiving mechanism 7B, and the position of the hook needle positioning mechanism 7D is located on the rear side of the wire-receiving mechanism 7B. Among them, the wiring post 7E1 includes a wiring sleeve 7E11 and a wiring pin 7E12. The wiring pin 7E12 is externally sleeved with the wiring sleeve 7E11, and the bottom of the wiring pin 7E12 is fixedly connected to the wiring connecting plate 7E2.

[0141] As Figure 9 、 Figures 16 - 17As shown, the wiring driving mechanism includes a wiring motor 7E6, a wiring gear 7E7, a wiring rack 7E5, a wiring guide rail 7E4 and a wiring pressing plate 7E3. The wiring motor 7E6 is fixedly connected to the bottom plate 8 by screws 12. The output shaft of the wiring motor 7E6 is connected to the wiring gear 7E7. The wiring gear 7E7 meshes with the wiring rack 7E5. Both the wiring rack 7E5 and the wiring pressing plate 7E3 are fixedly connected to the wiring connecting plate 7E2 by screws 12. The wiring guide rail 7E4 is embedded between the wiring rack 7E5 and the wiring pressing plate 7E3 and the wiring guide rail 7E4 is fixedly connected to the bottom plate 8 by screws 12. The wiring guide rail 7E4 can slide between the wiring rack 7E5 and the wiring pressing plate 7E3.

[0142] After the wire pulling mechanism 7F pulls the wire, the wiring motor 7E6 operates. The wiring motor 7E6 drives the wiring gear 7E7 to rotate. The wiring gear 7E7 drives the wiring rack 7E5 to move linearly along the wiring guide rail 7E4. The wiring rack 7E5 drives the wiring connecting plate 7E2 to move linearly, thereby driving the six wiring posts 7E1 to move linearly along the six strip-shaped chutes 7011 on the second connecting plate 701 respectively, as Figure 11 shown. It is the position diagram after the movement of the wiring posts 7E1. After the six wiring posts 7E1 move, they will pull the binding thread 11, so that the binding thread 11 is tensioned on the positioning pin 7D1 of the crochet positioning mechanism 7D.

[0143] As Figure 10 shown, there are three crochet positioning mechanisms 7D. The three crochet positioning mechanisms 7D are located on the same straight line and are respectively connected to the bottom plate 8. The tops of the three crochet positioning mechanisms 7D respectively pass through the three second through slots 7013 on the second connecting plate 701. The crochet positioning mechanism 7D is located directly below the wire hook and wire dividing mechanism through hole 903 on the support plate 9 and the wire hook hole 2171 of the conveying pressing plate 217.

[0144] In this embodiment, as Figure 18As shown, the crochet positioning mechanism 7D includes a positioning pin 7D1, an upper positioning sleeve 7D2, an inner positioning washer 7D3, a positioning compression spring 7D4, a positioning seat body 7D5, a lower positioning sleeve 7D6 and an outer positioning washer 7D7. A through hole for installing the positioning seat body 7D5 is provided on the base plate 8. The positioning seat body 7D5 is fixedly connected to the through hole on the base plate 8 by a screw 12. There is a certain gap below the through hole of the base plate 8 to facilitate the positioning pin 7D1 to slide downward. The interior of the positioning seat body 7D5 is provided with a positioning through hole, the top end of the positioning through hole is fixedly connected with an upper positioning sleeve 7D2, and the bottom end is fixedly connected with a lower positioning sleeve 7D6. The positioning column pin 7D1 sequentially penetrates the inner hole of the upper positioning sleeve 7D2, the positioning through hole of the positioning seat body 7D5, and the inner hole of the lower positioning sleeve 7D6, and the positioning column pin 7D1 can slide in the inner hole of the upper positioning sleeve 7D2, the positioning through hole of the positioning seat body 7D5, and the inner hole of the lower positioning sleeve 7D6. The bottom of the positioning column pin 7D1 is connected with The outer positioning washer 7D7 is located below the outer side of the lower positioning sleeve 7D6. The middle of the positioning column pin 7D1 is fixedly connected with the inner positioning washer 7D3. The positioning compression spring 7D4 is sleeved on the outside of the positioning column pin 7D1. The top of the positioning compression spring 7D4 is connected to the inner positioning washer 7D3, and the bottom is connected to the lower positioning sleeve 7D6. The inner positioning washer 7D3 and the positioning compression spring 7D4 are located in the positioning through hole of the positioning seat body 7D5. The top of the positioning column pin 7D1 is provided with a hook needle slot 7D11. When the positioning compression spring 7D4 is in a natural state, the top of the positioning column pin 7D1 is higher than the upper positioning sleeve 7D2.

[0145] The sequence diagram of the first hook needle 4A2 hooking the binding thread 11 is as follows Figure 19 As shown in (1)-(3) in . Figure 19 As shown in (1), the binding thread 11 is tensioned in front of the positioning pin 7D1 of the hook positioning mechanism 7D (as shown in FIG. Figure 11 As shown), when the first hook needle 4A2 moves downward, Figure 9 As shown in (2), the first hook needle 4A2 is inserted into the hook needle slot 7D11. Under the pressure applied by the first hook needle 4A2, the positioning pin 7D1 moves downward in the inner hole of the upper positioning sleeve 7D2, the positioning through hole of the positioning seat body 7D5 and the inner hole of the lower positioning sleeve 7D6, and the binding wire 11 tightened on the positioning pin 7D1 slides into the groove of the first hook needle 4A2. Figure 19 As shown in (3), the first hook 4A2 moves upward, and the positioning pin 7D1 is reset under the action of the positioning compression spring 7D4. The process of hooking the binding thread 11 by the groove of the hook hook in the hook hook thread dividing mechanism 4C is similar to the above. Although the groove at the bottom of the hook hook thread dividing mechanism 4C is not facing forward, the angle between the groove of the hook hook thread dividing mechanism 4C and the front is very small, and the binding thread 11 stretched on the positioning pin 7D1 of the hook hook positioning mechanism 7D can also be successfully hooked.

[0146] In this embodiment, a tangent structure (not shown in the figure) is further provided between the wire supporting mechanism 7B and the clip opening mechanism 7C. The tangent structure can be an automatic tangent or a manual tangent, and is used to cut the binding thread 11. The tangent structure adopts the prior art and includes a cutter and a driving device for driving the cutter to move. The driving device drives the cutter to move, and the cutter moves to the tensioned binding thread 11 to cut the binding thread 11.

[0147] In this embodiment, as Figures 20 - 23 shown, the hook wire and wire separating mechanism 4 includes a hook wire driving mechanism, a hook wire top plate 404, a hook wire intermediate plate 401, a left hook needle mechanism 4A, a hook needle wire separating mechanism 4C, and a right hook needle mechanism 4B. The hook wire top plate 404 is fixedly connected to the support plate 9 through a support rod 416 and a screw 12. The support plate 9 is connected to the bottom plate 8 through a support rod 416 and a screw 12. The hook wire driving mechanism is arranged on the hook wire top plate 404, and the hook wire driving mechanism is connected to the hook wire intermediate plate 401 and is used to drive the hook wire intermediate plate 401 to move linearly up and down. The hook wire intermediate plate 401 is located below the hook wire top plate 404. The left hook needle mechanism 4A, the hook needle wire separating mechanism 4C, and the right hook needle mechanism 4B are sequentially connected to the hook wire intermediate plate 401 from left to right. As Figure 4 shown, a square hook wire and wire separating mechanism through hole 903 for the left hook needle mechanism 4A, the hook needle wire separating mechanism 4C, and the right hook needle mechanism 4B to pass through is provided on the support plate 9. Figure 2 The enlarged view of the middle hook wire and wire separating mechanism 4 is as Figure 20 shown.

[0148] As Figure 20 shown, the left hook needle mechanism 4A and the right hook needle mechanism 4B have the same structure, and both include a first joint 4A1 and a first hook needle 4A2. The first hook needle 4A2 is fixedly connected to the first joint 4A1 through a screw 12. The outer surface of the first joint 4A1 is provided with a step and a thread. The first joint 4A1 is installed in a reserved installation hole on the hook wire intermediate plate 401 through a lock nut 409. The lock nut 409 is locked on the thread of the first joint 4A1, and the lock nut 409 is in close contact with the upper end surface of the reserved installation hole. The step of the first joint 4A1 is in close contact with the lower end surface of the reserved installation hole.

[0149] As Figure 24 in (a) of Figure 24 in (b) of Figure 25 in (a) of Figure 25As shown in (b) therein, the crochet thread separating mechanism 4C includes a thread separating rack 4C1, a thread separating compression spring 4C2, a thread separating positioning sleeve 4C3, a thread separating joint 4C4 and a crochet hook. A vertical through hole 4C41 is provided inside the thread separating positioning sleeve 4C3. A vertical through hole 4C41 is provided inside the thread separating joint 4C4, and a horizontal slot 4C42 is provided at the bottom. The horizontal slot 4C42 communicates with the bottom of the vertical through hole 4C41 inside the thread separating joint 4C4. The thread separating positioning sleeve 4C3 is fixedly connected to the thread separating joint 4C4. The top of the thread separating rack 4C1 is provided with a convex block so that the top is T-shaped. The thread separating rack 4C1 penetrates into the vertical through hole 4C41 of the thread separating positioning sleeve 4C3 and the vertical through hole 4C41 of the thread separating joint 4C4. The convex block at the top of the thread separating rack 4C1 is located above the outside of the thread separating positioning sleeve 4C3. The thread separating compression spring 4C2 is sleeved outside the thread separating rack 4C1 and is located inside the vertical through hole 4C41 of the thread separating positioning sleeve 4C3. One end of the thread separating compression spring 4C2 is connected to the convex block at the top of the thread separating rack 4C1, and the other end is connected to the thread separating joint 4C4. The crochet hook is composed of a left half crochet hook 4C5 and a right half crochet hook 4C6. Semi-grooves are respectively provided at the bottoms of the left half crochet hook 4C5 and the right half crochet hook 4C6. When the bottoms of the left half crochet hook 4C5 and the right half crochet hook 4C6 are closed, as Figure 25 shown in (a) therein, the two semi-grooves are closed to form a groove for hooking the binding thread 11. When the bottoms of the left half crochet hook 4C5 and the right half crochet hook 4C6 are separated, as Figure 25 shown in (b) therein, the two semi-grooves are separated to open the hooked binding thread 11, forming a thread hole 14. Semi-teeth 4C51 are provided at the tops of both the left half crochet hook 4C5 and the right half crochet hook 4C6. The semi-teeth 4C51 of the left half crochet hook 4C5 and the semi-teeth 4C51 of the right half crochet hook 4C6 are engaged, and the semi-teeth 4C51 of the left half crochet hook 4C5 and the semi-teeth 4C51 of the right half crochet hook 4C6 are respectively rotatably connected to the inner wall of the horizontal slot 4C42 of the thread separating joint 4C4 through pins. The semi-teeth 4C51 of the left half crochet hook 4C5 are engaged with the thread separating rack 4C1. A step is provided on the outer surface of the thread separating joint 4C4, and a thread is provided on the outer surface above the step. The thread separating joint 4C4 is placed in a reserved installation hole on the thread hooking intermediate plate 401. The step is located at the lower end face of the reserved installation hole. The locking nut 409 is locked on the thread of the thread separating joint 4C4 and the locking nut 409 is locked on the upper end face of the reserved installation hole. If it is necessary to adjust the angle of the thread separating joint 4C4 in the reserved installation hole on the thread hooking intermediate plate 401, only loosen the locking nut 409, rotate the thread separating joint 4C4 to a suitable position, and then lock the locking nut 409. It should be noted here that, as Figure 20 , Figure 23As shown, the grooves at the bottoms of the left crochet needle mechanism 4A and the right crochet needle mechanism 4B face directly forward, while the groove at the bottom of the crochet needle wire separating mechanism 4C does not face directly forward but has a certain inclination, which can make the positions of the half grooves at the bottoms of the left half crochet needle 4C5 and the right half crochet needle 4C6 after separation be like the positions of the two points in g shown in Figure 4 , facilitating the binding thread 11 clamped by the two threading mechanisms 6 to pass through the wire hole 14. Although Figure 20 , Figure 23 shows that the groove at the bottom of the crochet needle wire separating mechanism 4C faces directly forward, but the installation angle between the crochet needle wire separating mechanism 4C and the crochet wire intermediate plate 401 can be adjusted by loosening the lock nut 409 according to actual needs.

[0150] The initial positions of the left crochet needle mechanism 4A, the crochet needle wire separating mechanism 4C, and the right crochet needle mechanism 4B are as shown in Figure 23 . When the crochet wire driving mechanism works, the crochet wire driving mechanism drives the crochet wire intermediate plate 401 to move linearly upward, thereby driving the left crochet needle mechanism 4A, the crochet needle wire separating mechanism 4C, and the right crochet needle mechanism 4B on the crochet wire intermediate plate 401 to move linearly upward. When the crochet needle wire separating mechanism 4C moves upward and touches the crochet wire top plate 404, the wire separating rack 4C1 moves downward, driving the half teeth 4C51 of the left half crochet needle 4C5 to rotate, and the half teeth 4C51 of the right half crochet needle 4C6 also rotate simultaneously. As shown in Figure 20 , the left half crochet needle 4C5 and the right half crochet needle 4C6 separate.

[0151] In this embodiment, as shown in Figure 20 , the crochet wire driving mechanism includes a crochet wire motor 412, a left crochet wire rack 406, a right crochet wire rack 410, a left crochet wire gear 407, and a right crochet wire gear 411. The crochet wire motor 412 is fixedly connected to the crochet wire top plate 404 by screws 12. The output shaft of the crochet wire motor 412 is simultaneously connected to one end of the transmission shaft 408 and the right crochet wire gear 411. The other end of the transmission shaft 408 is rotatably connected to the left crochet wire bracket 405 through a bearing 13. The left crochet wire bracket 405 is fixedly connected to the crochet wire top plate 404 by screws 12. The left crochet wire gear 407 is connected to the transmission shaft 408. The left crochet wire gear 407 meshes with the left crochet wire rack 406, and the right crochet wire gear 411 meshes with the right crochet wire rack 410. The left crochet wire rack 406 and the right crochet wire rack 410 are parallel to each other, and the bottoms of both penetrate through the crochet wire top plate 404 and are fixedly connected to the crochet wire intermediate plate 401 by screws 12. As shown in Figure 22As shown, a left limit shaft is lock-connected to the left hook wire bracket 405 through a nut. A left limit sleeve 415 is connected to the left limit shaft. The left hook wire rack 406 is embedded in the left limit sleeve 415 and can move within the left limit sleeve 415. The purpose of the left limit sleeve 415 is to prevent the left hook wire rack 406 from falling off. The right hook wire bracket 414 and the hook wire top plate 404 are fixedly connected by a screw 12. A right limit shaft is lock-connected to the right hook wire bracket 414 through a nut. A right limit sleeve 413 is connected to the right limit shaft. The right hook wire rack 410 is embedded in the right limit sleeve 413 and can move within the right limit sleeve 413. The purpose of the right limit sleeve 413 is to prevent the right hook wire rack 410 from falling off.

[0152] In this embodiment, one end of a slide bar 403 is also fixedly connected to the hook wire top plate 404 by a screw 12. The hook wire intermediate plate 401 and the slide bar 403 are slidably connected through a linear bearing 402. The hook wire intermediate plate 401 can slide on the slide bar 403. The other end of the slide bar 403 can be connected to the support plate 9 by a screw 12.

[0153] In this embodiment, as Figure 4 shown, two wire threading mechanisms 6 are provided on the support plate 9.

[0154] As Figures 26 - 29 shown, the wire threading mechanism 6 includes a wire clamping motor 615, a wire clamping bracket 612, a wire clamping gear 610, a wire clamping rack 611, a clamp sleeve 605, a clamp shaft 606, and a cable pulling mechanism. The wire clamping motor 615 is connected to the wire clamping bracket 612 by a screw 12. The wire clamping bracket 612 is elastically arranged on the support plate 9. As Figure 4As shown in the figure, a strip-shaped thread clamping motor through hole 901 through which the thread clamping motor 615 penetrates and can move is provided on the support plate 9. A guide groove is provided in the thread clamping bracket 612. The thread clamping rack 611 is embedded in the guide groove and can slide in the guide groove. The output shaft of the thread clamping motor 615 is connected with a thread clamping gear 610. The thread clamping gear 610 meshes with the thread clamping rack 611. The end of the thread clamping rack 611 is fixedly connected with a clamp shaft 606. The end of the clamp shaft 606 is rotatably connected with a first clamp 601 and a second clamp 602 through a clamp pin 603. A torsion spring 604 is provided between the first clamp 601 and the second clamp 602. The end of the thread clamping rack 611 is elastically connected with a clamp sleeve 605 through a thread clamping compression spring 613. The clamp sleeve 605 is sleeved outside the clamp shaft 606, the first clamp 601 and the second clamp 602, and the clamp shaft 606 can slide in the clamp sleeve 605. The cable pulling mechanism is connected with the clamp sleeve 605 through a steel wire rope 609. The cable pulling mechanism is used to tighten the clamp sleeve 605 through the steel wire rope 609, so that the first clamp 601 and the second clamp 602 at the end of the clamp shaft 606 slide out of the clamp sleeve 605 and are separated under the action of the torsion spring 604. In the natural state of the torsion spring 604, the first clamp 601 and the second clamp 602 are in a separated state.

[0155] In this embodiment, the thread clamping bracket 612 is elastically arranged on the support plate 9. Specifically: one end of a tension spring 617 is fixedly connected with the thread clamping bracket 612 through a screw 12. The other end of the tension spring 617 is fixedly connected with a hook plate 618. The hook plate 618 and the support plate 9 are fixedly connected through a screw 12. A T-shaped sliding groove is provided at the top of the thread clamping bracket 612. A thread clamping guide rail 614 is fixedly connected to the support plate 9. A T-shaped sliding block is provided at the bottom of the thread clamping guide rail 614. The T-shaped sliding block at the bottom of the thread clamping guide rail 614 is slidably connected with the T-shaped sliding groove at the top of the thread clamping bracket 612. Guide rail baffles 616 are fixedly connected to both ends of the thread clamping guide rail 614 through screws 12. The guide rail baffles 616 prevent the T-shaped sliding block from falling off the T-shaped sliding groove. The function of elastically arranging the thread clamping bracket 612 on the support plate 9 is that when the first clamp 601 and the second clamp 602 clamp and tighten the binding thread 11, after the binding thread 11 is tightened, under the action of the tension spring 617, the thread clamping bracket 612 will move on the support plate 9 to prevent the binding thread 11 from being broken due to over-tightening. Therefore, due to the action of the tension spring 617, the binding thread 11 has a certain degree of tightness.

[0156] In this embodiment, as Figures 26 - 29As shown, the drawstring mechanism includes a drawstring motor 620 and a wire wheel 619. The drawstring motor 620 is connected to the support plate 9. The output shaft of the drawstring motor 620 is connected to the wire wheel 619. A steel wire rope 609 is wound around the wire wheel 619. A wire clamping rack 611 is fixedly connected with a wire clamping joint 608. A sliding hole is provided on the wire clamping joint 608. The clamp sleeve 605 is fixedly connected with a pull rod 607. The pull rod 607 passes through the sliding hole and is connected to the steel wire rope 609. When the drawstring motor 620 operates, the drawstring motor 620 drives the wire wheel 619 to rotate. The wire wheel 619 tightens or loosens the clamp sleeve 605 through the steel wire rope 609 and the pull rod 607. When the clamp sleeve 605 is tightened, as shown in (b) of Figure 30 , the clamp one 601 and the clamp two 602 at the end of the clamp shaft 606 slide out of the clamp sleeve 605 and separate under the action of the torsion spring 604. When the clamp sleeve 605 is loosened, as shown in (a) of Figure 30 , the clamp one 601 and the clamp two 602 at the end of the clamp shaft 606 slide into the clamp sleeve 605.

[0157] In this embodiment, as shown in Figures 31 - 32 , the knotting mechanism 5 includes an axial sliding drive mechanism, a radial rotation drive mechanism, a circumferential rotation drive mechanism, and a jaw mechanism. The jaw mechanism is located inside the outer sleeve 506 and can axially slide and radially rotate inside the outer sleeve 506. The outer sleeve 506 is fixedly connected to the knotting bracket 507. The axial sliding drive mechanism and the radial rotation drive mechanism are both arranged on the knotting bracket 507. The axial sliding drive mechanism is used to drive the jaw mechanism to axially slide inside the outer sleeve 506 (i.e., move in the direction of the axis center line, that is, move back and forth in the length direction). The radial rotation drive mechanism is used to drive the jaw mechanism to radially rotate inside the outer sleeve 506 (i.e., move in the circumferential direction, that is, move in the 360-degree direction of the cross-section). The circumferential rotation drive mechanism is arranged on the support plate 9. The circumferential rotation drive mechanism is used to drive the knotting bracket 507, the axial sliding drive mechanism, the radial rotation drive mechanism, and the jaw mechanism to rotate together as a whole. The top of the jaw mechanism is provided with a jaw. The jaw is connected with a jaw opening and closing mechanism for driving the jaw to open and close.

[0158] As shown in Figure 31 , the circumferential rotation drive mechanism includes a knotting motor one 521, a knotting gear one 519, and a knotting gear two 518. The knotting motor one 521 is connected to the support plate 9 through screws 12. The output shaft of the knotting motor one 521 is connected to the knotting gear one 519. The knotting gear one 519 meshes with the knotting gear two 518. The knotting gear two 518 is simultaneously fixedly connected to the knotting shaft 516 and the knotting bracket 507. The knotting shaft 516 is rotatably connected to the support plate 9. As shown in Figure 4As shown, two knotting mechanism mounting holes 902 are provided on the support plate 9. The first knotting motor 521 is connected to one of the knotting mechanism mounting holes 902 through the screw 12. The other knotting mechanism mounting hole 902 is fixedly connected with a connection disk 517 through the screw 12. The knotting shaft 516 is rotationally connected to the connection disk 517.

[0159] As Figure 31 shown, the radial rotation driving mechanism includes a second knotting motor 515, a third knotting gear 514 and a fourth knotting gear 508. The second knotting motor 515 is connected to the knotting bracket 507 through the knotting connection plate 509 and the screw 12. The output shaft of the second knotting motor 515 is connected to the third knotting gear 514. The third knotting gear 514 meshes with the fourth knotting gear 508.

[0160] As Figure 32 shown, the axial sliding driving mechanism includes a third knotting motor 522 and a fifth knotting gear 523. The third knotting motor 522 is connected to the knotting bracket 507 through the screw 12. The output shaft of the third knotting motor 522 is connected to the fifth knotting gear 523.

[0161] As Figure 33As shown, the nozzle mechanism includes a nozzle shaft 504, a nozzle shaft sleeve 505 and a shaft sleeve joint 511. The bottom of the nozzle shaft sleeve 505 is fixedly connected to the shaft sleeve joint 511. The nozzle shaft 504 is located within the nozzle shaft sleeve 505 and can axially slide within the nozzle shaft sleeve 505. A compression spring washer 512 is provided at the bottom of the nozzle shaft 504, and the compression spring washer 512 is elastically connected to the shaft sleeve joint 511 by a nozzle compression spring 513. The nozzle shaft sleeve 505 is located inside the outer sleeve 506 and can axially slide and radially rotate within the outer sleeve 506. The outside of the nozzle shaft sleeve 505 is radially connected to the fourth knotting gear 508 and the nozzle shaft sleeve 505 can axially slide inside the fourth knotting gear 508. A strip-shaped inner notch 5051 is provided on the nozzle shaft sleeve 505, and an outer notch is provided on the outer sleeve 506. The fifth knotting gear 523 passes through the outer notch on the outer sleeve 506 and the strip-shaped inner notch 5051 on the nozzle shaft sleeve 505 and then meshes with the circular teeth on the outer surface of the nozzle shaft 504. There are multiple circular teeth on the outer surface of the nozzle shaft 504. When the third knotting motor 522 operates, the third knotting motor 522 drives the fifth knotting gear 523 to rotate, and the fifth knotting gear 523 drives the nozzle shaft 504 and the nozzle shaft sleeve 505 to axially move inside the outer sleeve 506. When the second knotting motor 515 operates, the second knotting motor 515 drives the third knotting gear 514 to rotate, the third knotting gear 514 drives the fourth knotting gear 508 to rotate, and the fourth knotting gear 508 drives the nozzle mechanism to radially rotate inside the outer sleeve 506. When the first knotting motor 521 operates, the first knotting motor 521 drives the first knotting gear 519 to rotate, the first knotting gear 519 drives the second knotting gear 518, the knotting shaft 516, the knotting bracket 507, and the entire nozzle mechanism to rotate. It should be noted that the first knotting gear 519 is not a full tooth, and there are some positions without teeth. When the first knotting gear 519 rotates to a position without teeth and meshes with the second knotting gear 518, even if the first knotting motor 521 continues to rotate, the second knotting gear 518, the knotting shaft 516, the knotting bracket 507, and the nozzle mechanism do not rotate. At this time, if the first knotting motor 521 continues to rotate, the wire drawing 510 will tighten the nozzle shaft 504, and the movable nozzle 502 and the fixed nozzle 501 will separate, that is, the nozzle opens. When the first knotting motor 521 rotates in reverse, the wire drawing 510 will loosen the nozzle shaft 504, and the movable nozzle 502 and the fixed nozzle 501 will close, that is, the nozzle closes. When the first knotting motor 521 continues to rotate in reverse and the first knotting gear 519 rotates to a position with teeth and meshes with the second knotting gear 518, the first knotting gear 519 rotates in reverse, driving the second knotting gear 518, the knotting shaft 516, the knotting bracket 507, and the entire nozzle mechanism to rotate in reverse.

[0162] As Figure 33As shown, the chuck includes a movable chuck 502 and a fixed chuck 501. The top of the chuck bushing 505 is fixedly connected to the fixed chuck 501. The top of the chuck shaft 504 is rotatably connected to the movable chuck 502, and the movable chuck 502 is rotatably connected to the fixed chuck 501. The chuck opening and closing mechanism includes a wire 510 and a wire reel 520. The output shaft of the knotting motor 521 is connected to the wire reel 520. The wire reel 520 is connected to the wire 510. The wire 510 passes through a reserved wire hole in the bushing joint 511 and is connected to the chuck shaft 504. When the knotting motor 521 operates, the knotting motor 521 drives the wire reel 520 to rotate. The wire reel 520 pulls the chuck shaft 504 through the wire 510. The chuck shaft 504 moves in the direction of the bushing joint 511, and the movable chuck 502 and the fixed chuck 501 are separated, that is, the chuck opens. On the contrary, when the wire 510 is loosened, under the reset action of the chuck compression spring 513, the chuck shaft 504 moves in the direction away from the bushing joint 511, and the movable chuck 502 and the fixed chuck 501 are closed, that is, the chuck closes.

[0163] In this embodiment, a through groove is provided in the knotting connecting plate 509. The chuck bushing 505 penetrates through the through groove of the knotting connecting plate 509. The chuck bushing 505 can axially slide and radially rotate in the through groove of the knotting connecting plate 509.

[0164] The installation position of the knotting mechanism 5 in this embodiment is as Figure 1 and Figure 2 shown. Figure 1 The enlarged view of the knotting mechanism 5 in Figure 31 is shown as Figure 2 The enlarged view of the knotting mechanism 5 in Figure 32 is shown as

[0165] The working process of the three-hole wire binding machine in this embodiment is as follows: The binding wire 11 is wound around the wire reel. After passing between the wire tensioning press plate 7A3 and the wire tensioning connection block 7A1, the binding wire 11 passes through the wire supporting mechanism 7B. First, the documents are placed in the pallet 202, and the conveying mechanism 2 starts to work. The conveying motor 216 runs, and the conveying motor 216 drives the box body 207 and the pallet 202 to move backward along the conveying guide rail 209. When moving below the drilling mechanism 3, the box body 207 and the pallet 202 stop moving. The three drill bits on the drilling mechanism 3 penetrate the documents on the pallet 202, forming three binding holes in the documents. After punching is completed, the drilling mechanism 3 resets, and the box body 207 and the pallet 202 continue to move backward along the conveying guide rail 209. When the box body 207 and the pallet 202 move backward above the conveying top plate 211, when the screw blocking blocks 2024 at the bottoms of the three sliding plates 2021 on the pallet 202 touch the bar on the upper surface of the conveying top plate 211 together, the three sliding plates 2021 stop moving backward. However, the box body 207, the pallet 202, and the documents continue to move backward under the drive of the conveying motor 216, so that the sliding plates 2021 move in the opposite direction (i.e., forward) in the sliding plate holes 2022 of the pallet 202, and the sliding plates 2021 avoid the binding holes already punched in the documents, forming a through hole 2023 in the sliding plate holes 2022 directly below the binding holes already punched in the documents. When the conveying push plate 206 touches the connecting rod cylindrical pin 219 between the upper connecting rod 212 and the lower connecting rod 213, the folding lifting bracket starts to rise, driving the conveying top plate 211 to rise. When the conveying top plate 211 rises, it just lifts the pallet 202 in the box body 207. After the pallet 202 drives the documents to rise, the top of the documents presses tightly against the conveying pressure plate 217, realizing the function of pressing the documents, and the conveying push plate 206 stops moving.The wire pulling mechanism 7F in the wire feeding mechanism 7 operates. The wire pulling motor 7F2 drives the wire pulling gear 7F3 to rotate. The wire pulling gear 7F3 drives the wire pulling rack 7F4 and the wire pulling chuck to move horizontally to the left together. When the wire pulling chuck moves to the left and passes through the clamping opening mechanism 7C on the right side of the wire bearing mechanism 7B, the clamping opening block 7C11 on the clamping opening seat 7C1 blocks the clamping opening mechanism 7C from rotating to the left. The lower wire pulling chuck 7F7 passes through the square groove 7C31 of the clamping opening mechanism 7C, and the upper wire pulling chuck 7F6 just touches the two slope blocks 7C5. The upper wire pulling chuck 7F6 passes above the slope blocks 7C5, and the upper wire pulling chuck 7F6 is separated from the lower wire pulling chuck 7F7, that is, the wire pulling chuck opens. Immediately afterwards, the separated upper wire pulling chuck 7F6 and the lower wire pulling chuck 7F7 touch the right end of the wire bearing sleeve 7B5. The wire bearing sleeve 7B5 and the wire bearing pipe 7B4 move to the left in the wire bearing connection block 7B1. Under the action of the wire pulling compression spring 7F5, the upper wire pulling chuck 7F6 and the lower wire pulling chuck 7F7 close, and when closing, they just clamp the binding thread 11 outside the wire bearing sleeve 7B5. The wire pulling motor 7F2 runs in the reverse direction, driving the wire pulling rack 7F4 to reset. The wire bearing sleeve 7B5 and the wire bearing pipe 7B4 reset under the action of the wire bearing compression spring 7B3. When the wire pulling rack 7F4 and the wire pulling chuck clamp the binding thread 11 and return to the right, they touch the clamping opening mechanism 7C. The clamping opening mechanism 7C rotates to the right below the wire pulling rack 7F4 and the wire pulling chuck. The wire pulling rack 7F4 and the wire pulling chuck pass through the two clamping opening mechanisms 7C, and the wire pulling rack 7F4 and the wire pulling chuck stop moving. The wiring motor 7E6 starts to operate. The wiring motor 7E6 drives the wiring gear 7E7 to rotate. The wiring gear 7E7 drives the wiring rack 7E5 to move linearly along the wiring guide rail 7E4. The wiring rack 7E5 drives the wiring connection plate 7E2 to move linearly, thereby driving the six wiring posts 7E1 to move linearly along the six strip-shaped sliding grooves 7011 on the second connection plate 701 respectively. The wiring posts 7E1 move to the position as shown in... Figure 11 After reaching the shown position, they stop moving. After the six wiring posts 7E1 move, they pull the binding thread 11, making the binding thread 11 taut on the positioning pin 7D1 of the hook needle positioning mechanism 7D. The hook line and wire splitting mechanism 4 starts to operate. The hook line motor 412 drives the right hook line gear 411, the transmission shaft 408, and the left hook line gear 407 to rotate together, thereby driving the right hook line rack 410 and the left hook line rack 406 to move downward. The right hook line rack 410 and the left hook line rack 406 drive the left hook needle mechanism 4A, the hook needle wire splitting mechanism 4C, and the right hook needle mechanism 4B on the hook line intermediate plate 401 to move downward. The bottoms of the left hook needle mechanism 4A, the hook needle wire splitting mechanism 4C, and the right hook needle mechanism 4B sequentially penetrate through... Figure 4 the hook line and wire splitting mechanism through hole 903 on the support plate 9 as shown in... Figure 7 the hook line hole 2171 of the conveying pressing plate 217 as shown in... Figure 8The slide plate 2021 shown in the figure avoids the through holes 2023 formed in the slide plate hole 2022 of the support plate 202 and is then inserted into the hook slots 7D11 of the three hook positioning mechanisms 7D, as shown in FIG. Figure 19 As shown, the binding thread 11 tensioned on the positioning pins 7D1 of the three hook positioning mechanisms 7D slides into the grooves at the bottom of the left hook mechanism 4A, the hook wire dividing mechanism 4C and the right hook mechanism 4B respectively, and the hook wire motor 412 runs in the opposite direction, driving the left hook mechanism 4A, the hook wire dividing mechanism 4C and the right hook mechanism 4B to move upward, and when the top of the dividing rack 4C1 of the hook wire dividing mechanism 4C touches the hook wire top plate 404, the dividing rack 4C1 in the hook wire dividing mechanism 4C moves downward, driving the half tooth 4C51 of the left half hook 4C5 to rotate, and the half tooth 4C51 of the right half hook 4C6 also rotates at the same time, as shown in FIG. Figure 20 As shown, the left half hook 4C5 and the right half hook 4C6 in the hook thread dividing mechanism 4C are separated, and the binding thread 11 hooked by the hook thread dividing mechanism 4C is opened to form a Figure 35 The thread hole 14 shown in FIG. 1 is a hole 14 in the left hook mechanism 4A. At this time, the groove position of the left hook mechanism 4A is Figure 4 e in the figure, the groove position of the right hook mechanism 4B is Figure 4 f, the positions of the half grooves of the left half crochet needle 4C5 and the right half crochet needle 4C6 in the crochet needle thread dividing mechanism 4C are respectively Figure 4 The two g's in the two threading mechanisms 6 are operated simultaneously, the clamping motor 615 drives the clamping gear 610 to rotate, thereby driving the clamping rack 611 to move, and the clamping rack 611 drives the clamp sleeve 605 and the clamp shaft 606 to move together, when the end of the clamp shaft 606 of the left threading mechanism 6 passes through the thread hole 14 and runs to the vicinity of the binding thread 11 hooked by the right hook mechanism 4B, and the end of the clamp shaft 606 of the right threading mechanism 6 passes through the thread hole 14 and runs to the vicinity of the binding thread 11 hooked by the left hook mechanism 4A, the rope pulling mechanism operates simultaneously, and the clamp sleeve 605 is tightened by the steel wire rope 609, so that the clamp 1 601 and the clamp 2 602 at the end of the clamp shaft 606 slide out of the clamp sleeve 605. The wire drawing mechanism 609 is used to draw the wires of the clamp 1 and the second clamp 602. The wires of the clamp 1 and the second clamp 602 are drawn out and separated under the action of the torsion spring 604. After the clamp 1 601 and the second clamp 602 reach the wire clamping position, the wire drawing mechanism releases the wire rope 609, and the clamp 1 601 and the second clamp 602 retract into the clamp sleeve 605 and clamp the binding wire 11. The wire clamping motor 615 runs in the opposite direction again, and the clamping rack 611 drives the clamp sleeve 605 and the clamp shaft 606 to move back. The binding wire 11 clamped by the clamp 1 and the second clamp 602 passes through the wire hole 14. When the two threading mechanisms 6 run at the same time, the binding wire 11 hooked by the left hook mechanism 4A and the binding wire 11 hooked by the right hook mechanism 4B are respectively clamped by the threading mechanism 6 and passed through the wire hole 14 and tightened. After being tightened, Figure 36As shown, it should be noted here that while the thread threading mechanism 6 clamps the binding thread 11, the thread hooking motor 412 needs to drive the left hook needle mechanism 4A, the hook needle thread separating mechanism 4C, and the right hook needle mechanism 4B to move downward to release the binding thread 11. At the same time, the thread cutting structure cuts the binding thread 11, and the wire pulling motor 7F2 drives the wire pulling gear 7F3 to rotate. The wire pulling gear 7F3 drives the wire pulling rack 7F4 and the wire pulling chuck to move horizontally to the left together. When the wire pulling chuck moves to the left and passes by the closest clip opening mechanism 7C to it, the wire pulling chuck opens to release the binding thread 11. Immediately afterwards, the thread clamping motor 615 runs in the reverse direction to tighten the binding thread 11. When the binding thread 11 is in the state as shown in Figure 36 When in the state shown, the knotting mechanism 5 starts to work. The knotting motor three 522 runs to drive the knotting gear five 523 to rotate, thereby driving the nozzle bushing 505 and the nozzle shaft 504 to move forward within the outer sleeve 506. After moving to the position shown in (1) of Figure 34 , the nozzle bushing 505 and the nozzle shaft 504 stop moving forward. Figure 34 This is a top view effect diagram. The knotting motor two 515 drives the knotting gear three 514 to rotate, thereby driving the nozzle bushing 505 and the nozzle shaft 504 to rotate within the outer sleeve 506 through the knotting gear four 508. After rotating to the angle shown in (2) of Figure 34 , the nozzle stops rotating. The knotting motor three 522 drives the knotting gear five 523 to rotate in the reverse direction, thereby driving the nozzle bushing 505 and the nozzle shaft 504 to move backward within the outer sleeve 506 to hook one side of the binding thread 11. After moving to the position shown in (3) of Figure 34 , the nozzle bushing 505 and the nozzle shaft 504 stop moving backward. The knotting motor two 515 drives the knotting gear three 514 to rotate, thereby driving the nozzle bushing 505 and the nozzle shaft 504 to rotate within the outer sleeve 506 through the knotting gear four 508. The rotation process of the nozzle is as shown in (4) of Figure 34 and (5) of Figure 34 . One side of the binding thread 11 winds around the nozzle bushing 505 to form a coil. After the nozzle rotates to the position shown in (5) of Figure 34 , it stops rotating. The knotting motor one 521 runs to drive the knotting gear one 519 to rotate, thereby driving the knotting bracket 507, the outer sleeve 506, and the entire nozzle mechanism to rotate through the knotting gear two 518 and the knotting shaft 516. The knotting bracket 507 rotates to the position as shown in Figure 34At the angle shown in (6), since the first knotting gear 519 is not a full tooth, when the first knotting gear 519 rotates to a position where no tooth meshes with the second knotting gear 518, the first knotting motor 521 continues to operate. The knotting bracket 507 does not rotate, but the first knotting motor 521 drives the wire drawing disc 520 to continue rotating, thereby tightening the wire 510 against the nozzle shaft 504. The nozzle shaft 504 moves backward in the nozzle shaft sleeve 505, and the fixed nozzle 501 and the movable nozzle 502 separate, and the nozzle opens. The third knotting motor 522 operates, driving the nozzle shaft sleeve 505 and the nozzle shaft 504 to move forward in the outer sleeve 506. The nozzle moves to the other side of the binding thread 11, and the nozzle shaft sleeve 505, the nozzle shaft 504, and the nozzle stop moving forward, as shown in Figure 34 shown in (6). The third knotting motor 521 operates in the reverse direction, driving the wire drawing disc 520 to rotate in the reverse direction. The wire 510 loosens the nozzle shaft 504. Under the action of the nozzle compression spring 513, the nozzle shaft 504 moves forward in the nozzle shaft sleeve 505, and the fixed nozzle 501 and the movable nozzle 502 close, clamping the binding thread 11 on the other side, as shown in Figure 34 shown in (7). The first knotting motor 521 continues to operate in the reverse direction. When the first knotting gear 519 rotates to a position where a tooth meshes with the second knotting gear 518, the first knotting gear 519 drives the knotting bracket 507, the outer sleeve 506, and the entire nozzle mechanism to rotate in the reverse direction through the second knotting gear 518 and the knotting shaft 516, until it rotates to the angle shown in Figure 34 shown in (8) and then stops rotating. The second knotting motor 515 drives the third knotting gear 514 to rotate, thereby driving the nozzle shaft sleeve 505 and the nozzle shaft 504 to rotate in the outer sleeve 506 through the fourth knotting gear 508, until it rotates to the angle shown in Figure 34 shown in (9) and then stops rotating. The third knotting motor 522 rotates in reverse, thereby driving the nozzle shaft sleeve 505 and the nozzle shaft 504 to move backward in the outer sleeve 506, retracting the previously wound coil. The retracting process is as shown in Figure 34 shown in (9). Then the third knotting motor 522 and the first knotting motor 521 operate simultaneously. The third knotting motor 522 drives the nozzle shaft sleeve 505 and the nozzle shaft 504 to move forward in the outer sleeve 506, and the first knotting motor 521 drives the knotting bracket 507, the outer sleeve 506, and the entire nozzle mechanism to rotate through the second knotting gear 518 and the knotting shaft 516, tightening the binding thread 11, as shown in Figure 34As shown in (10) therein, the knotting is completed. During the process of the secondary knotting by the knotting mechanism 5, both of the two thread threading mechanisms 6 need to perform corresponding thread loosening or tightening operations, that is, the thread clamping motor 615 drives the thread clamping rack 611 to move back and forth, and the first clamp 601 and the second clamp 602 clamp the binding thread 11 and move back and forth to achieve the thread loosening or tightening operation, preventing the binding thread 11 from being broken due to excessive tightness. After the knotting mechanism 5 completes the knotting, the first clamp 601 and the second clamp 602 of the thread threading mechanism 6 are opened to release the binding thread 11, and the jaws of the knotting mechanism 5 are opened to release the binding thread 11. Finally, all mechanisms are reset.
