[0026] like Figures 1-6 As shown, a yarn cutting machine includes an end cap assembly 1, which includes a head end cap 2 and a yarn cutting blade 3 disposed inside the head end cap 2. The head end cap 2 has a tapered cutting section 4 at its inner end, and the outer diameter of the cutting section 4 gradually increases from the inner to the outer. Two cutting grooves 5 extending to the cutting section 4 are symmetrically arranged on the circumferential wall of the head end cap 2. The two ends of the yarn cutting blade 3 are respectively inserted into the cutting grooves 5. The head end cap 2 also has a head cover plate 6 at its inner end, with the cutting edge of the yarn cutting blade 3 facing the head cover plate 6. A pull rod 7 with its inner end connected to the yarn cutting blade 3 is slidably connected to the head cover plate 6. The machine also includes a blade holder assembly 8 connected to the pull rod 7 and capable of driving the pull rod 7 to reciprocate axially.

[0027] This invention places the end yarn blade inside the machine head end cover and fixes the blade through a cutting groove to form a built-in cutting structure, reducing space occupation; the pull rod on the machine head cover is connected to the blade holder assembly, driving the blade to move back and forth along the axis to achieve cutting, avoiding blade exposure and improving operational safety; the design of the conical cutting part and the blade edge facing the machine head cover ensures cutting accuracy and solves the space and safety problems caused by the split design.

[0028] Specifically, the tool post assembly 8 includes an upper tool post base 9, a lower tool post base 10, a driver mounting plate 11, a cylinder seat mounting plate 12, and a pull-out cylinder seat 13. The lower tool post base 10, driver mounting plate 11, and cylinder seat mounting plate 12 are horizontally arranged, while the pull-out cylinder seat 13 is vertically arranged. The driver mounting plate 11 and the lower tool post base 10 are connected by a first slider rail structure. The pull-out cylinder seat 13 is fixed to the driver mounting plate 11 by the cylinder seat mounting plate 12. A lifting assembly 14 is provided on the upper tool post base 9. A first translation assembly 15 that can drive the driver mounting plate 11 to move horizontally is provided between the driver mounting plate 11 and the lower tool post base 10. A pull-out cylinder 16 is provided on the pull-out cylinder seat 13. A sliding separation connection structure 17 is provided between the output shaft end of the pull-out cylinder 16 and the pull-out rod 7. The tool holder assembly forms a stable drive structure through the combination of multiple components. The first slider rail structure ensures smooth horizontal movement of the driver mounting plate. The lifting component is height-adjustable, and the first translation component drives the driver mounting plate to move horizontally, allowing the pull-out cylinder to move to the end cover position of the machine head. The pull-out cylinder and pull-out rod are then connected through a sliding separation connection structure. The pull-out cylinder and pull-out rod can also be separated when cutting is not required. This design makes the tool holder more flexible in operation. Since the pull-out cylinder does not need to be constantly connected to the pull-out rod, it also reduces the design difficulty of the tool holder, allowing the tool holder to adapt to cutting needs under different working conditions. This solves the problems of fixed position and poor adaptability of traditional tool holders. At the same time, the sliding separation connection structure also facilitates component maintenance and replacement.

[0029] Specifically, the sliding separation connection structure 17 includes a pull rod seat connected to the output shaft of the puller cylinder 16. A pull rod 19 with a T-shaped groove 18 is fixedly connected to the pull rod seat. The upper and lower sides of the T-shaped groove 18 pass through the pull rod 19. An annular limiting member 20, which can move vertically into or out of the T-shaped groove 18, is fixedly sleeved on the outer end of the puller rod 7. The sliding separation connection structure uses the T-shaped groove and the annular limiting member to cooperate. The annular limiting member can move vertically into or out of the T-shaped groove, realizing the quick connection and separation of the puller rod and the pull rod. This design simplifies the connection operation, improves the efficiency of component assembly and disassembly, solves the problem of cumbersome assembly and disassembly in traditional connection methods, and ensures stable power transmission during cutting.

[0030] Specifically, the first translation component 15 includes a first rack 21 fixed to the bottom of the lower tool holder base 10 and a first motor 22 fixed to the driver mounting plate 11. The output end of the first motor 22 is connected to a traveling gear 23 through a reducer, and the traveling gear 23 meshes with the first rack 21. The first translation component meshes with the traveling gear through the first rack and is driven by the first motor through the reducer, causing the driver mounting plate to move horizontally along the lower tool holder base. The rack and pinion transmission has high precision and stable driving force, ensuring that the driver mounting plate moves smoothly and accurately, solving the problem of insufficient precision in traditional translation drive methods, and improving the accuracy of the cutting position. The first translation component can also move the drawbar cylinder horizontally to a position corresponding to the end cap of the machine head to facilitate the subsequent docking of the drawbar and the drawbar rod.

[0031] Specifically, the lifting assembly 14 includes a vertical slide rail 24. A lifting seat 25, which is slidably connected to the vertical slide rail 24, is fixedly connected to the upper tool holder base 9. The lifting seat 25 is equipped with a second motor 26, the output end of which is connected to a lifting gear 27. A second rack 28 is vertically arranged on the vertical slide rail 24, and the lifting gear 27 and the second rack 28 mesh. The lifting assembly utilizes the vertical slide rail and the lifting seat for slidable connection. The second motor drives the lifting gear and the second rack to mesh, thereby achieving the lifting and adjusting of the upper tool holder base. This structure provides smooth lifting and high adjustment precision, accurately adapting to different cutting height requirements. It solves the problems of inconvenient adjustment and low precision of traditional lifting structures, enhancing the equipment's versatility. The lifting assembly allows the annular limiting piece 20 to move vertically into or out of the T-shaped slot 18.

[0032] Specifically, the first slider rail structure includes two parallel first rails 29 fixed on both sides of the bottom of the lower blade holder base 10, and a first slider 30 slidably connected to the top of the driver mounting plate 11. The first slider rail structure, composed of two parallel first rails and corresponding first sliders, ensures that the driver mounting plate remains horizontally stable during movement, preventing deviation. This design improves the guiding and smooth movement of the driver mounting plate, solves the problem of unstable guidance with a single rail, and ensures the stability of the cutting process.

[0033] Preferably, a yarn-cutting bar 31 is provided on the cylinder base mounting plate 12, and two vertically arranged cutting blades 32 are fixedly connected to the yarn-cutting bar 31. A second translation component 33 is also provided between the upper blade holder base 9 and the lower blade holder base 10, which can drive the lower blade holder base 10 to move horizontally. The yarn-cutting bar and cutting blades on the cylinder base mounting plate can cut the yarn, and the second translation component drives the lower blade holder base to move horizontally, expanding the cutting range. This design enables the equipment to have both head yarn and yarn-cutting functions, realize integrated operation, solve the problem of traditional equipment having single function and requiring multiple devices to cooperate, and improve work efficiency.

[0034] Specifically, the second translation component 33 includes a third rack 34 fixed to the top of the lower tool holder base 10 and a third motor 35 fixed to the upper tool holder base 9. The output end of the third motor 35 is connected to a drive gear 36 via a reducer, and the drive gear 36 meshes with the third rack 34. The second translation component, through the meshing of the third rack and the drive gear, drives the lower tool holder base to move horizontally via the third motor and reducer. The rack and pinion transmission ensures precise movement and sufficient power. This design makes the movement range of the lower tool holder base controllable and the position adjustment precise, solving the problems of limited range and insufficient precision of traditional translation drive methods, and adapting to more cutting scenarios.

[0035] Specifically, the lower tool holder base 10 is connected to the upper tool holder base 9 via a second slider rail structure. This second slider rail structure slidably connects the lower and upper tool holder bases, ensuring the stability and smoothness of the lower tool holder base during horizontal movement and preventing wobbling. This design enhances the guiding nature of the lower tool holder base's movement and, in conjunction with the second translation component, further improves movement accuracy, ensuring the reliability of the cutting operation.

[0036] Specifically, the second slider rail structure includes two parallel second slide rails 37 fixed on both sides of the bottom of the upper tool holder base 9, and a second slider 38 slidably connected to the top of the lower tool holder base 10. The second slider rail structure uses two parallel second slide rails in cooperation with the second slider, ensuring balanced force distribution on the lower tool holder base during movement and smoother sliding. This design improves the load-bearing capacity and durability of the rail structure, solves the problems of easy wear and poor stability associated with single slider rails, and extends the service life of the equipment.
