[0022] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1 , Figure 2 An embodiment of this utility model provides an automatic mouth rope machine, comprising a main body 1, a top rope cutting module 5 fixedly mounted on one side of the main body 1, a rope feeding module 4 fixedly mounted on one side of the upper end face of the main body 1, a folding module 3 fixedly mounted on one side of the upper end face of the main body 1, a first cylinder 6 mounted on the lower part of the front end face of the folding module 3, a sliding table 7 fixedly mounted on the other side of the upper end face of the main body 1, a first steel plate frame 8 bolted to the upper end face of the sliding table 7, a small cylinder 9 bolted to the top surface inside the first steel plate frame 8, a control box 11 fixedly mounted on the rear part of the upper end face of the main body 1, a support frame 2 fixedly mounted on the rear part of the upper end face of the main body 1, a placement rack 12 mounted on the upper end face of the support frame 2, and two sleeve needles 10 fixedly mounted on one side of the first steel plate frame 8, with flat steel spring hooks slidably mounted inside the sleeve needles 10.

[0024] Specifically, during use, the main body 1 supports and fixes the other components. A control box 11 is fixed to the upper rear of the main body 1. The control box 11 is the core of the automatic neck lace machine, determining the actions and timing of the four mechanical parts. It uses a Siemens SMART288 PLC as the main unit, processing relevant inputs and controlling related relays through output points to drive specific solenoid valves, thereby driving the relevant machinery. The support frame 2 fixed to the rear of the main body 1 is connected to a placement rack 12 via wire. The placement rack 12 can hold the roller rope reel during use. A top rope cutting module 5 is fixed to one side of the main body 1, connecting the rope to the cannula needle 10 and cutting the used rope. A folding module 3 is located at the upper end of the main body 1, folding the bag. The other upper side of the main body 1 is connected to a sliding table 7. The upper end of the sliding table 7 is connected via… Bolts are used to fix the first steel plate frame 8. The lower end of one side of the first steel plate frame 8 is fixed to the first cylinder 6. The first cylinder 6 allows the first steel plate frame 8 to move. A small cylinder 9 is fixed to the inner top surface of the first steel plate frame 8. The sleeve needle 10 consists of a steel pipe, a flat steel bar, and a spring hook. The steel pipe has a diameter of 8mm and a length of 400mm. One end is fixed to the first steel plate frame 8, and the other end is machined into a 30-degree bevel. A flat steel bar with a width of 4mm, a thickness of 2mm, and a length of 450mm is inserted into the steel pipe. One end of the flat steel bar passes through the through hole of the first steel plate frame 8 and is connected to the hydraulic arm of the small cylinder 9. The other end is connected to a 50mm long spring hook. The flat steel bar and the spring hook are rigid. The flat steel spring hooks, connected together, move left and right within the steel pipe. After the hydraulic arm retracts (small cylinder 9), the flat steel spring hooks move to the left within the pipe. Upon retraction, the spring hooks are fully pulled into the pipe by the flat steel and are compressed due to the inner wall of the pipe. Conversely, during hydraulic arm extension, the flat steel is pushed to the right within the pipe. Upon extension, the spring hooks extend 30mm beyond the pipe fork and are in a freely open state. The first steel plate frame 8, the sleeve needle 10, the small cylinder 9, the first cylinder 6, and the sliding table 7 form the rope-threading module. Under the program control of the control box 11, the rope-threading module slides to the right limit. At this point, the sleeve needle... 10 penetrates the folded bag, drives the small cylinder 9 to extend the hydraulic arm, pushes the flat steel spring hook to the right, and makes the spring hook extend out of the tube fork and be in a free-springing state. At this time, the prepared mouth rope can be sent into the spring hook through the top rope cutting module 5. After the top rope action is completed, drives the small cylinder 9 to retract the hydraulic arm, pulls the flat steel spring hook to the left, so that the spring hook grabs the mouth rope and drags it into the steel pipe. The spring hook is in a constrained state, and the hooking rope action is completed. After the hooking rope is completed, drives the first cylinder 6 to make the sliding table 7 slide to the left, driving the needle table to move to the left together, pulling out the sleeve needle 10 inserted into the bag, and at the same time completing the insertion of the mouth rope.

[0025] Reference Figure 4The folding module 3 includes a support plate 301. Multiple bagging rods 305 are fixedly installed on the front end face of the support plate 301. Electric push rods 302 are bolted to the upper and lower ends of the rear end face of the support plate 301. Connecting plates 303 are fixedly installed at the output ends of the two electric push rods 302. Three steel columns 304 are fixedly installed on the front end face of the two connecting plates 303. The steel columns 304 are slidably installed inside the support plate 301.

[0026] Specifically, the main structure of the folding module 3 during use includes a support plate 301. Multiple bagging rods 305 are fixed at the front end of the support plate 301. The bagging rods 305 can be used to place bags. After the bags are placed, the electric push rod 302 is driven, causing the connecting plate 303 to drive the steel column 304 to move towards each other. The moving structure is such that the bag opening is folded, making it convenient for the cannula needle 10 to pass through.

[0027] Reference Figure 3 The rope feeding module 4 includes two first pneumatic slides 401. A pneumatic manipulator 402 is bolted to one side of each of the two first pneumatic slides 401. A placement rod 403 is fixedly installed at the upper end of one side of each of the two first pneumatic slides 401.

[0028] Specifically, the function of the rope feeding module 4 is to pull down the rope from the roller rope reel to a certain length and precisely deliver the rope end to a certain position. The core of the rope feeding module 4 is two pneumatic manipulators 402. The pneumatic manipulators 402 are installed on the first pneumatic slide 401. Under the control of the host, the left and right first pneumatic slides 401 and their fixed pneumatic manipulators 402 work together in a certain working sequence to complete the task of feeding rope to a fixed point and a fixed length.

[0029] Reference Figure 3 The shearing top rope module 5 includes a mounting platform 501, a support frame 502 fixedly mounted on the upper surface of the mounting platform 501, a second pneumatic slide 503 fixedly mounted on the upper surface of the support frame 502, a pneumatic shear 504 bolted to the upper surface of the second pneumatic slide 503, a second steel plate frame 505 bolted to the inner top surface of the support frame 502, a second cylinder 506 bolted to the lower surface of the second steel plate frame 505, and two top rope arms fixedly mounted at the output end of the second cylinder 506.

[0030] Specifically, the module is connected to the main body 1 via a mounting platform 501. A support frame 502 is fixed to the upper surface of the mounting platform 501. The upper end of the support frame 502 has a shearing structure, and the inner top of the support frame 502 has a rope-pushing structure. The function of the rope-pushing structure is to horizontally push the tensioned rope into the spring hook after the rope feeding and hooking are prepared. Two Y-shaped forks are respectively installed on the two hydraulic arms of the second cylinder 506. Under program control, when the rope-threading module moves to the right limit, the robot grips the rope, making the rope tensioned. In the tight state, the small cylinder 9 extends the hydraulic arm, and when the spring hook is in the free state, the second cylinder 506 extends the hydraulic arm, and the fork arm pushes the tie rope in the fork mouth to move to the left until it reaches the spring hook. In the shearing structure, the pneumatic scissors 504 are installed on the second pneumatic slide 503 to form a mobile shearing robot. After the top rope mechanism completes the top rope action, the second pneumatic slide 503 moves to the left and opens the pneumatic scissors 504, so that the cutting edge of the pneumatic scissors 504 reaches the position of the tie rope, and closes the pneumatic scissors 504 to cut the tie rope.

[0031] Working principle: When in use, put the bag on the outer end of the bagging rod 305, start the folding module 3 to fold the bag, and after folding, the rope threading module slides to the right limit. At this time, the sleeve needle 10 penetrates the folded bag, drives the small cylinder 9 to extend the hydraulic arm, pushes the flat steel spring hook to the right, and makes the spring hook extend out of the tube fork and be in a free-springing state. At this time, the prepared mouth rope can be sent into the spring hook through the top rope cutting module 5.

[0032] After the top rope action is completed, the small cylinder 9 is driven to retract the hydraulic arm, pulling the flat steel spring hook to the left, so that the spring hook grabs the tie rope and drags it into the steel pipe. The rope hooking action is completed. After the rope hooking is completed, the first cylinder 6 is driven to slide the sliding table 7 to the left, driving the needle table to move to the left as well, pulling out the cannula needle 10 inserted into the bag, and at the same time completing the insertion of the tie rope. After the top rope mechanism completes the top rope action, the second pneumatic sliding table 503 moves to the left and opens the pneumatic scissors 504, so that the blade of the pneumatic scissors 504 reaches the position of the tie rope, and closes the pneumatic scissors 504 to cut the tie rope.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
