[0026] This disclosure provides a processing apparatus for valve packing, including a packing support, a cutting bed, a turntable, and a movable cutter head. At least one packing support rod is mounted on the packing support, and the packing support rod is rotatably connected to the packing support. Valve packing is wound around the packing support rod. One end of the packing support rod is provided with a handle interface for connecting a handle configured to rotate the packing support rod. The two opposite ends of the cutting bed are designated as the first end and the second end. The packing support is connected to the first end, and the plane of the packing support forms a predetermined angle with the cutting bed. The turntable is located at the second end of the cutting bed, and a positioning shaft is located at the center of the turntable. The movable cutter head is located at the edge of the cutting bed, defining an X-axis parallel to the edge of the cutting bed. The movable cutter head is configured to perform a shearing motion along the X-axis direction.

[0027] The valve packing processing apparatus disclosed herein includes a packing support rod mounted on a packing bracket. The valve packing is directly wound onto the packing support rod, which is rotatably connected to the packing bracket. During valve packing processing, the valve packing can be directly extracted from the packing support rod for cutting, significantly improving operational convenience. Furthermore, a movable cutter head is mounted on the cutting bed, allowing for flexible movement and enabling multi-angle and free-size cutting of the valve packing, thus enhancing cutting flexibility and processing efficiency.

[0028] For ease of understanding, please refer to the following: Figures 1 to 3 The specific structure and working principle of the valve packing processing device disclosed herein will be described in detail with reference to one embodiment.

[0029] like Figure 1 As shown, this disclosure provides a valve packing processing apparatus, including a packing support 1, a cutting bed 4, a turntable 5, and a movable cutter head 6. The packing support 1 is provided with at least one packing support rod 2, which is rotatably connected to the packing support 1. The packing support rod 2 is used to support the valve packing roll to be processed, and its diameter needs to be adapted to the inner diameter of the valve packing roll to prevent slippage or excessive compression deformation. One end of the packing support rod 2 is provided with a handle interface for connecting a handle 3. The handle 3 is configured to drive the packing support rod 2 to rotate. When the handle 3 rotates, the valve packing is pulled out or retracted along with the rotation of the packing support rod 2.

[0030] The cutting bed 4 has a certain rigidity and wear resistance, and can be supported by steel plates, high-strength engineering plastics, or composite materials. The two opposite ends of the cutting bed 4 are designated as the first end and the second end. The packing support 1 is connected to the first end, and the plane of the packing support 1 forms a predetermined angle with the cutting bed 4. In this embodiment, the predetermined angle can be between 90° and 180°. Within this predetermined angle range, the packing support 1 is inclined relative to the cutting bed 4. This inclined setting allows the operator to extract the valve packing in a more natural posture, significantly reducing arm and waist fatigue, and making observation and operation easier. Furthermore, the inclined angle helps the valve packing smoothly transition from a coiled state to the horizontal cutting bed 4, reducing jamming and frictional resistance, and improving the stability and torsional resistance of the entire device during the valve packing extraction process.

[0031] The turntable 5 is used to receive and wind the cut valve packing. The turntable 5 is located at the second end of the cutting bed 4, allowing the cut valve packing to be directly wound, reducing material handling steps. A positioning shaft 11 is located at the center of the turntable 5 for positioning during the winding of the valve packing. Specifically, the valve is fitted onto the positioning shaft 11 and rotated around it. The surface of the turntable 5 can be provided with anti-slip texture to prevent the valve packing from slipping off during winding.

[0032] like Figure 2 , Figure 3 As shown, the movable cutter head 6 is used to cut valve packing. The movable cutter head 6 is positioned at the edge of the cutting bed 4, defining an X-axis parallel to the edge of the cutting bed 4. The movable cutter head 6 is configured to perform a shearing motion along the X-axis. Specifically, the movable cutter head 6 moves via a guide mechanism. The hard cutter head can be a hook blade or a cutting blade, etc., to ensure clean and sharp cutting of packing materials of various types, avoiding burrs. Furthermore, the movable cutter head 6 is equipped with a gripping part. This gripping part can be positioned on the same side as the turntable 5, allowing the operator to naturally approach the turntable 5 after cutting, facilitating immediate picking up and winding of the cut packing, resulting in a smooth process. Alternatively, it can be positioned on the opposite side of the turntable 5; no limitation is made here.

[0033] The specific working process of the valve packing processing device in this embodiment is as follows: When valve packing needs to be prepared, turn handle 3. Handle 3 drives the packing support rod 2 to rotate. The direction of rotation can be clockwise or counterclockwise. As the packing support rod 2 rotates, the valve packing wound on the packing support rod 2 is released and guided along the inclined packing bracket 1 to the horizontal cutting bed 4. The valve packing is straightened and flattened on the cutting bed 4. The operator continues to turn handle 3 until the length is reached. After confirming that the length is correct, the operator moves the moving cutter head 6 along the X-axis to the predetermined cutting point and applies force to the moving cutter head 6 (pressing or pulling). The blade cleanly and neatly cuts the valve packing laid flat on the bed, and the straight guide ensures that the cut is straight and without bevels. Finally, the cut valve packing of a fixed length is rotated around the positioning shaft 11, and the turntable 5 is rotated to neatly and tightly wind the entire piece of packing onto the valve. The positioning shaft 11 ensures the concentricity and regularity of the winding.

[0034] In this embodiment, the valve packing processing device has a valve packing support rod 2 rotatably connected to the packing bracket 1, allowing for quick extraction of the valve packing. Furthermore, a movable cutter head 6 is provided at the edge of the cutting bed 4, enabling flexible cutting of the valve packing and significantly improving processing efficiency.

[0035] Furthermore, such as Figure 1 As shown, the movable cutter head 6 is also configured to perform a shearing motion along the Y-axis, where the Y-axis is perpendicular to the X-axis. In actual processing, the dimensions of valve packing require not only length but also width to accommodate valves of different specifications. In this embodiment, the movable cutter head 6 can move not only along the X-axis but also along the Y-axis, enabling flexible cutting of the valve packing's length and width.

[0036] Specifically, the operator pushes or pulls the cutter head along the Y-axis (perpendicular to the packing extraction direction) to longitudinally cut the packing laid on the bed to the target width. This step can be performed after the required length has been extracted. The operator then pushes or pulls the cutter head along the X-axis (parallel to the edge of the bed) to transversely cut the packing of a specific width (or the entire width of the packing) to the target length. Depending on the processing requirements, the length can be cut first and then the width, or vice versa. Alternatively, bidirectional cutting can be performed continuously after a single positioning (e.g., cutting the width first along the Y-axis, then cutting the length along the X-axis). This allows for precise and flexible control of the final length and width of the valve packing, meeting the needs of various complex and non-standard dimensions.

[0037] In one embodiment of this disclosure, such as Figure 1 As shown, the shearing motion of the moving cutter head 6 is a reciprocating motion along the Z-axis, which is perpendicular to both the X and Y axes. Compared to traditional horizontal push-pull cutting, shearing along the Z-axis avoids beveled cuts, material compression deformation, or delamination tearing caused by the tilt of the moving cutter head 6. This is especially crucial for multi-layer braided materials, graphene composites, or fillers containing metal cores. Specifically, the moving cutter head 6 can move along the X or Y axis on the cutting bed 4. After moving to a predetermined position, it performs a reciprocating shearing motion along the Z-axis. Based on this, the moving cutter head 6 can achieve triaxial movement, greatly improving the flexibility and convenience of cutting.

[0038] To improve cutting accuracy, a scale is provided on the cutting bed 4, with bidirectional calibration along both the X and Y axes. A high-strength stainless steel / tempered glass bidirectional scale can be embedded in the surface or edge of the cutting bed 4. In one embodiment, the valve packing is first rotated to a predetermined length along the X-axis, and then a predetermined width is calibrated using the scale as a reference. Cutting is then performed based on the determined predetermined length and width. In this embodiment, the scale can be positioned on the edge of the cutting bed 4, and the moving cutter head 6 can move according to the calibrated dimensions of the scale to improve cutting accuracy. Furthermore, a locking mechanism is provided on the moving cutter head 6 to lock its position when cutting is required, preventing slippage during the cutting process.

[0039] In one embodiment of this disclosure, the handle interface is hexagonal, square, or splined, and the shape of the insertion end of the handle 3 matches the handle interface. The hexagonal handle interface adopts a classic regular hexagonal cross-section design, with its six equilateral faces forming a stable geometric structure. When the operator rotates the handle 3, all six faces of the hexagonal interface are simultaneously stressed, making it particularly suitable for extracting thicker metal-wound packing or multi-layer composite packing. Furthermore, the hexagonal structure has a self-positioning function; precise alignment is not required when inserting the handle 3, enabling quick installation and significantly improving operational efficiency. The square interface provides stable torque output, preventing packing deformation due to excessive torque, and its good torsional rigidity ensures no loosening during prolonged use. The spline interface ensures stable transmission performance during long-term, high-load packing extraction, while the multi-tooth meshing design effectively disperses stress concentration, extending the interface's service life. In this embodiment, multiple packing support rods 2 can be provided, each corresponding to a different handle interface.

[0040] In one embodiment of this disclosure, a sliding limit block is provided on the cutting bed surface 4. The sliding limit block is configured to move along the X-axis or Y-axis direction. The sliding limit block can move to a predetermined position based on the required length and width of the valve packing to limit the valve packing, ensuring the stability and accuracy of the cutting process.

[0041] In one embodiment of this disclosure, an annular limiting member 7 is provided on the edge of the turntable 5. The annular limiting member 7 is configured to restrict the winding path of the valve packing. Specifically, the annular limiting member 7 has a limiting opening. When the cut valve packing needs to be wound, the operator passes one end of the packing through the limiting opening, making it fit against the valve on the turntable 5. At this time, the winding function of the turntable 5 is activated, and the packing begins to wind under the drive of the turntable 5. The annular limiting member 7, through its continuous annular structure, forms a physical constraint boundary on the outside of the packing, forcing the packing to wind tightly along a predetermined path.

[0042] In one embodiment of this disclosure, a ratchet mechanism is provided at the bottom of the turntable 5, and the ratchet mechanism is coaxially arranged with the positioning shaft 11. When the turntable 5 is winding valve packing, the operator starts the drive device, and the turntable 5 drives the coaxial ratchet to rotate clockwise (or counterclockwise). At this time, the pawl is engaged in the tooth groove of the ratchet under the action of the return spring. As the ratchet rotates, the pawl slides along the slope of the tooth groove. The whole process is smooth and unobstructed. The power is transmitted to the turntable 5 through the meshing of the pawl and the ratchet, realizing the stable winding of the packing. When winding stops or an unexpected external force causes the turntable 5 to have a tendency to rotate in the opposite direction, the reverse rotation of the ratchet will cause the pawl to immediately lock into the tooth groove, effectively preventing the turntable 5 from rotating in the opposite direction. This one-way locking characteristic ensures that the wound valve packing will not loosen or retract due to external force, and also maintains the integrity of the valve packing winding state.

[0043] For safety reasons, the surface of the movable cutter head 6 is equipped with a protective cover 8, which is a split-type cover. When cutting is required, the protective cover 8 is opened to expose the movable cutter head 6 for cutting. After cutting is completed, the protective cover 8 is closed. This not only prevents the movable cutter head 6 from accidentally injuring the operator, but also prevents the movable cutter head 6 from being contaminated and corroded by long-term exposure to the environment, thus improving the service life of the movable cutter head 6.

[0044] In one embodiment of this disclosure, a support frame 9 is provided at the bottom of the cutting bed surface 4, and casters 10 are provided at the bottom of the support frame 9. Specifically, the support frame 9 is a height-adjustable structure, which allows the support frame 9 to be raised and lowered, making it convenient for operators to adjust the height according to their own height. The casters 10 are universal casters to facilitate flexible movement of the entire device.

[0045] The valve packing processing apparatus disclosed herein includes a packing support rod 2 mounted on a packing support 1. The valve packing is directly wound onto the packing support rod 2, and the packing support rod 2 is rotatably connected to the packing support 1. During valve packing processing, the valve packing can be directly extracted from the packing support rod 2 for cutting, significantly improving operational convenience. Furthermore, a movable cutter head 6 is mounted on the cutting bed 4. The movable cutter head 6 can move flexibly, enabling multi-angle and free-size cutting of the valve packing, thus improving cutting flexibility and processing efficiency.
