Description

Technical Field

[0001] This invention relates to the field of ring-type chipper technology, and more particularly to a blade ring disassembly device for a ring-type chipper. Background Technology

[0002] Ring chippers are used to produce wood shavings or similar materials for manufacturing wood-based panels, such as particleboard or similar products. They are fed in the form of loose material or wood chips. The ring chipper has an outer rotating cutter ring and a rotating, driven crushing wheel, also known as a rotor, inside the cutter ring.

[0003] Existing blade ring disassembly devices lack measures to position the blade ring during progressive disassembly, which makes the blade ring prone to misalignment and instability during disassembly, causing the blades on the blade ring to shift and deviate, thus affecting the normal operation of the ring-type blade slicer. Summary of the Invention

[0004] This invention discloses a blade ring disassembly device for a ring-type chipper, which aims to solve the technical problem in the prior art where the existing ring-type chipper cannot position the blade ring during disassembly, resulting in blade ring displacement and instability.

[0005] This invention proposes a blade ring disassembly device for a ring-type shaving machine, comprising a machine body with a cutting chamber inside. A blade ring body is disposed within the cutting chamber, and multiple circumferentially evenly distributed blades are disposed on the blade body. A central shaft is disposed within each blade, and a central positioning module is disposed on the central shaft. Two symmetrical push rods are disposed on the outside of the blade ring body, each push rod having a hydraulic rod at one end. Both hydraulic rods are located on the machine body. The central positioning module includes a push ring, the inner wall of which is movably connected to the outside of the central shaft. A spring is fixedly connected to the outside of the push ring. The external sliding connection is a hollow rod two, and the external fixed connection of the push ring is a slide rod. The external sliding connection of the slide rod is a displacement sensor, and the displacement sensor is equipped with a wire. The shaft rod is equipped with a support and stabilization module, and the external of the machine body is equipped with a mounting frame. The bottom of the mounting frame is fixedly connected with multiple symmetrical universal wheels and hydraulic rod six. The output end of each hydraulic rod six is ​​fixedly connected with a load-bearing plate. The support and stabilization module includes three equidistantly distributed rotating seats. The external of each of the three rotating seats is equipped with a contact frame. The external of each contact frame is equipped with a rubber pad. The external of each rubber pad is in contact with the inner wall of the blade ring body.

[0006] By incorporating a body, cutting chamber, push rod, cutter ring body, blade, mounting frame, spindle, spindle positioning module, and support and stabilization module, the device utilizes the spindle positioning module to quickly and accurately position the rotation axis of the cutter ring body. This effectively assists in ensuring that the cutter ring body does not shift or deform during disassembly from the machine body, preventing damage to the cutter ring body and the machine body due to deformation during reuse, and ensuring the functionality of the slicer.

[0007] In a preferred embodiment, the mounting frame is externally fixedly connected to a holding groove, which contains a counterweight. Both inner walls of the mounting frame have sliding grooves, and a common receiving groove is slidably connected within these grooves. Two symmetrical circular holes are formed on the inner wall of the mounting frame away from the receiving groove, and hydraulic rods are fixedly connected to each hole. The output ends of both hydraulic rods are fixedly connected to the outside of the receiving groove. A movable groove is formed on the receiving groove, and a moving platform is slidably connected within it. A hydraulic rod is fixedly connected to the upper side of the moving platform. The output end of the pressure rod is fixedly connected to a fixing component. The inner wall of the fixing component is fixedly connected to the end of the shaft rod away from the machine body. A slot is opened on the moving platform, and a thin rod is movably connected in the slot. A motor is fixedly connected to the upper side of the moving platform. The output end of the motor is connected to the upper side of the thin rod through a coupling. A gear is fixedly connected to the bottom of the thin rod. A rectangular groove is opened on the bottom inner wall of the movable groove. A rack is fixedly connected to one inner wall of the rectangular groove. The rack meshes with the gear. An external gear ring is movably connected to the outside of the shaft rod. The outside of the shaft rod is fixedly connected to... There is a second motor. The output end of the second motor is connected to a second gear via a coupling. The second gear meshes with an external gear ring, which is fixedly connected to the side opposite to the push ring. A fitting groove is provided on the side of the push ring away from the external gear ring. Three circumferentially equidistant rectangular blocks are arranged in the fitting groove. Each rectangular block is fixedly connected to the side opposite to the outer side of the shaft rod. The three rectangular blocks are slidably connected to the same fitting ring. The outer side of the fitting ring is slidably connected to the inner wall of the fitting groove. Three circumferentially equidistant pre-reserved slots are provided on the inner wall of the fitting groove near the external gear ring. The inner walls of the groove and the reserved groove are all fixedly connected to hydraulic rods three. The output ends of hydraulic rods three are all fixedly connected to the side of the fitting ring near the outer toothed ring. The upper side of the hollow rod two is fixedly connected to a support frame, and three rollers are provided on the support frame. The bottom inner wall of the hollow rod one is fixedly connected to a spring. The end of the spring near the hollow rod two is fixedly connected to a round rod. The outside of the round rod is slidably connected to the inner wall of the hollow rod one, and the upper side of the round rod is fixedly connected to the top inner wall of the hollow rod two. An opening is opened on the outside of the hollow rod two, and a fixing bolt is provided in the opening.

[0008] By incorporating a shaft center positioning module, the module utilizes displacement sensors and a sliding rod to record the trajectory of the support frame, which is in contact with the inner wall of the cutter ring body, rotating around the shaft center. Based on this trajectory, the offset between the shaft center and the shaft center of the cutter ring body is calculated. This allows the device to quickly and accurately measure the offset between the shaft center and the cutter ring body, thereby greatly reducing the workload of operators, improving the efficiency of shaft center positioning of the cutter ring body, and ultimately improving the overall efficiency of disassembling the cutter ring body.

[0009] In a preferred embodiment, a mounting ring is slidably connected to the outside of the spindle. The mounting ring has three circumferentially equidistant grooves on the side away from the cutter ring body. The inner walls of the three grooves are movably connected to the outside of three rotating seats. A compression ring is slidably connected to the outside of the spindle, with the side of the compression ring close to the outside of the three rotating seats. A mounting plate is fixedly connected to the side of the spindle away from the cutter ring body. Three circumferentially equidistant hydraulic rods are fixedly connected to the side of the mounting plate close to the compression ring. The output ends of the three hydraulic rods are all fixedly connected to the outside of the compression ring. A circular groove is formed on the spindle. A disc is slidably connected within the circular groove. The inner wall of the circular groove has three circumferentially equidistant rectangular openings, each of which is slidably connected to... Each of the three connecting plates is fixedly connected to the side opposite to the mounting ring. A notch is formed on the side of the circular groove away from the mounting ring, and a hydraulic rod four is fixedly connected within the notch. The output end of the hydraulic rod four is fixedly connected to the outside of the disc. Hollow rods three are fixedly connected to the outside of each of the three rotating seats. Motors three are fixedly connected to the inner wall of each hollow rod three near the rotating seat. The output end of each motor three is connected to a screw via a coupling. A sleeve is provided on the outside of each screw, and the outside of each sleeve is slidably connected to the inner wall of the hollow rod three. A hollow rod four is fixedly connected to the side of each sleeve away from the rotating seat, and the inner wall of each hollow rod four is slidably connected to the outside of the hollow rod three on the same side. The side of each hollow rod four away from the rotating seat is fixedly connected to the outside of the contact frame on the same side.

[0010] By incorporating a support and stabilization module, the module utilizes an installation ring and a compression ring to keep the rotating seat folded within the blade ring body as the shaft enters, thus preventing the contact frame from hooking onto the blades on the blade ring body. This ensures the stability of the device and the blade ring body. The rotating seat drives the retractable hollow rod four, allowing the contact frame to stably support blade ring bodies of different sizes. This ensures that the blade ring body remains relatively stable when being removed from the machine, preventing damage and deformation to the blade ring body and its blades.

[0011] As can be seen from the above, the blade ring disassembly device for a ring-type slicer provided by the present invention can quickly and accurately position the rotation axis of the blade ring body, thereby effectively assisting the device in ensuring that the blade ring body does not shift or deform during the disassembly process from the machine body. This avoids damage to the blade ring body and the machine body due to deformation when the blade ring body is reused, thus ensuring the effectiveness of the slicer's function.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] The present invention discloses a blade ring disassembly device for a ring-type chipper, which is mainly applied to the scenario where the existing ring-type chipper cannot be positioned during blade ring disassembly, resulting in blade ring displacement and instability.

[0024] Reference Figure 1-9A blade ring disassembly device for a ring-type shaving machine includes a body 1, a cutting chamber 2 on the body 1, a blade ring body 4 inside the cutting chamber 2, and multiple circumferentially equidistant blades 5 on the blade ring body 4. A spindle 7 is installed inside each blade 5, and a spindle positioning module 8 is installed on the spindle 7. Two symmetrical push rods 3 are located outside the blade ring body 4, each with a hydraulic rod 7 13 at one end. Both hydraulic rods 7 13 are located on the body 1. The spindle positioning module 8 includes a push ring 814, the inner wall of which is rotatably connected to the outer side of the spindle 7 via a bearing. A spring 826 is attached to the outer side of the push ring 814 via a tensioning rib, and a hollow rod 8 is slidably connected to the outer side of the spring 826. 28. The outer side of the push ring 814 is connected to a slide rod 830 by bolts. The outer side of the slide rod 830 is slidably connected to a displacement sensor 831. The displacement sensor 831 is provided with a wire 832. The support and stabilization module 9 is provided on the shaft rod 7. The outer side of the machine body 1 is provided with a mounting frame 6. The bottom of the mounting frame 6 is connected to multiple symmetrical universal wheels 10 and hydraulic rods 11 by bolts. The output end of the hydraulic rods 11 is connected to a load-bearing plate 12 by bolts. The support and stabilization module 9 includes three equally spaced rotating seats 902. The outer side of each of the three rotating seats 902 is provided with a contact frame 911. The outer side of each contact frame 911 is provided with a rubber pad 912. The outer side of each rubber pad 912 is in contact with the inner wall of the blade ring body 4.

[0025] Specifically, after the cutter ring body 4 in the machine body 1 is pushed out of the machine body 1 by the push rod 3 on the machine body 1, the universal wheel 10 is used to move the mounting frame 6 to a position roughly aligned with the cutter ring body 4. The hydraulic rod 11 and the load-bearing plate 12 are used to support the mounting frame 6. The shaft center positioning module 8 is used to push it into the center position of the cutter ring body 4. The shaft center positioning module 8 is used again to accurately position the shaft center position of the cutter ring body 4 on the push rod 3. After positioning, the support and stabilization module 9 is used to provide three-point support for the cutter ring body 4, so that the cutter ring body 4 can be supported on the shaft. Maintaining stability on the core rod 7, the shaft center positioning module 8 is used again to lift the cutter ring body 4 and disengage it from the push rod 3, thus removing the cutter ring body 4 from the machine body 1. The device utilizes the shaft center positioning module 8 to quickly and accurately position the rotation axis of the cutter ring body 4, thereby effectively assisting the device in ensuring that the cutter ring body 4 does not shift or deform during the disassembly process from the machine body 1. This prevents the cutter ring body 4 from being damaged by deformation during reuse, ensuring the functionality of the slicer.

[0026] Reference Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7In a preferred embodiment, a holding groove 801 is bolted to the outside of the mounting frame 6, and a counterweight 802 is provided inside the holding groove 801. Sliding grooves 806 are provided on both inner walls of the mounting frame 6, and the same receiving groove 803 is slidably connected within the two sliding grooves 806. Two symmetrical circular holes are provided on the inner wall of the side of the mounting frame 6 away from the receiving groove 803, and hydraulic rods 807 are bolted to both holes. The output ends of the two hydraulic rods 807 are bolted to the outside of the receiving groove 803. A movable groove 808 is provided on the receiving groove 803, and a moving platform 809 is slidably connected within the movable groove 808. A hydraulic rod 804 is bolted to the upper side of the moving platform 809. The output end is bolted to a fixing member 805. The inner wall of the fixing member 805 is bolted to the end of the shaft rod 7 away from the machine body 1. A slot is provided on the moving table 809, and a thin rod is rotatably connected to the slot through a bearing. A motor 810 is bolted to the upper side of the moving table 809. The output end of the motor 810 is connected to the upper side of the thin rod through a coupling. A gear 811 is bolted to the bottom of the thin rod. A rectangular slot 812 is provided on the inner wall of the bottom of the movable slot 808. A rack 813 is bolted to one inner wall of the rectangular slot 812. The rack 813 meshes with the gear 811. An external gear ring 815 is rotatably connected to the outside of the shaft rod 7 through a bearing. A motor 815 is bolted to the outside of the shaft rod 7. 817, the output end of motor 817 is connected to gear 816 via a coupling. Gear 816 meshes with external gear ring 815. The external gear ring 815 is bolted to the opposite side of push ring 814. A fitting groove 818 is provided on the side of push ring 814 away from external gear ring 815. Three circumferentially equidistant rectangular blocks 819 are provided in the fitting groove 818. The opposite side of rectangular blocks 819 to the outer side of shaft 7 is connected by tie rods. The three rectangular blocks 819 are slidably connected to the same fitting ring 820. The outer side of fitting ring 820 is slidably connected to the inner wall of fitting groove 818. Three circumferentially equidistant reserved grooves 821 are provided on the inner wall of fitting groove 818 near external gear ring 815. The inner wall of 21 is bolted with hydraulic rod three 822, and the output end of hydraulic rod three 822 is bolted to the side of the fitting ring 820 near the outer toothed ring 815; the upper side of hollow rod two 828 is bolted with a support frame 823, and three equally spaced rollers 824 are provided on the support frame 823; the bottom inner wall of hollow rod one 825 is bolted with a spring 826, and the end of spring 826 near hollow rod two 828 is bolted with a round rod 827, the outside of round rod 827 is slidably connected to the inner wall of hollow rod one 825, and the upper side of round rod 827 is bolted to the top inner wall of hollow rod two 828; the outside of hollow rod two 828 is provided with an opening, and a fixing bolt 829 is provided in the opening.

[0027] Specifically, after the cutter ring body 4 in the machine body 1 is pushed out of the machine body 1 by the push rod 3 on the machine body 1, the mounting frame 6 is moved to a position roughly aligned with the cutter ring body 4 using the casters 10. The mounting frame 6 is supported by the hydraulic rod 11 and the load-bearing plate 12. The hydraulic rod 807 is activated, and the hydraulic rod 807 pushes the receiving groove 803 to move in the direction of the machine body 1, so that the shaft rod 7 on the fixing member 805 can be inserted into the cutter ring body 4. The fixing bolt 829 is rotated to release the fixing bolt 829 from the hollow rod 805. Locked by spring 826, hollow rod 28 extends from hollow rod 1 825, allowing roller 824 on support bracket 823 to fit against the inner wall of cutter ring body 4. Hydraulic rod 2 807 is closed, motor 2 817 is started, and motor 2 817 drives external gear ring 815, which meshes with gear 2 816, to rotate. This external gear ring 815 drives push ring 814 to rotate. During the rotation of push ring 814, since the shaft rod 7 is not on the rotation axis of cutter ring body 4, the shaft rod 7 is not on the rotation axis of cutter ring body 4. As the inner wall of the support bracket 823 moves along the inner wall of the cutter ring body 4, it extends and retracts on the hollow rod 825. The displacement sensor 831 on the hollow rod 828 maps the movement trajectory of the hollow rod 828 onto the slide rod 830, thereby recording the trajectory of the rotation around the axis 7. Based on the trajectory, the offset between the axis of the axis 7 and the axis of the cutter ring body 4 is calculated, and the motor 810 is started. The motor 810 drives the gear 811 to mesh with the rack 813. The rotation causes the moving table 809 to move the shaft rod 7 laterally on the receiving groove 803. The hydraulic rod 804 is activated, which drives the shaft rod 7 to move vertically, so that the shaft rod 7 coincides with the axis of the cutter ring body 4. After the coincidence, the hydraulic rod 822 is activated. The output end of the hydraulic rod 822 pulls the fitting ring 820 into the fitting groove 818, so that the fitting ring 820 is engaged with the rectangular block 819, so that the push ring 814 stops rotating. The fixing bolt 829 is tightened, so that the hollow rod 828 stops sliding.

[0028] In specific application scenarios, the shaft positioning module 8 is mainly used in the shaft positioning process. That is, the shaft positioning module 8 uses the displacement sensor 831 and the slide bar 830 to record the trajectory of the support frame 823, which is in contact with the inner wall of the cutter ring body 4, rotating around the shaft rod 7. Based on the trajectory, the offset between the shaft rod 7 and the shaft of the cutter ring body 4 is calculated. This allows the device to quickly and accurately measure the offset between the shaft rod 7 and the shaft of the cutter ring body 4, thereby greatly reducing the workload of the operator, improving the efficiency of shaft positioning of the cutter ring body 4, and thus improving the overall efficiency of disassembling the cutter ring body 4.

[0029] Reference Figure 8 and Figure 9In a preferred embodiment, a mounting ring 901 is slidably connected to the outside of the spindle 7. The mounting ring 901 has three circumferentially spaced grooves on the side away from the cutter ring body 4. The inner walls of the three grooves are rotatably connected to the outside of three rotating seats 902 via bearings. A compression ring 908 is slidably connected to the outside of the spindle 7. The side of the compression ring 908 closest to the mounting ring 901 is in contact with the outside of the three rotating seats 902. The side of the spindle 7 away from the cutter ring body 4 is connected by bolts. A mounting plate 909 is connected to the extrusion ring 908. Three circumferentially equidistant hydraulic rods 910 are bolted to the side of the mounting plate 909. The output ends of the three hydraulic rods 910 are bolted to the outside of the extrusion ring 908. A circular groove 903 is formed on the shaft rod 7. A disc 904 is slidably connected within the circular groove 903. Three circumferentially equidistant rectangular openings 905 are formed on the inner wall of the circular groove 903. A connecting plate 906 is slidably connected within each rectangular opening 905. The side of the connecting plate 906 opposite to the mounting ring 901 is bolted together. A notch is provided on the side of the circular groove 903 away from the mounting ring 901, and a hydraulic rod 907 is bolted into the notch. The output end of the hydraulic rod 907 is bolted to the outside of the disc 904. Hollow rods 913 are bolted to the outside of each of the three rotating seats 902. Motors 914 are bolted to the inner wall of the hollow rods 913 on the side closest to the rotating seat 902. The output of the motors 914... Each end is connected to a screw 915 via a coupling. Each screw 915 is provided with a sleeve 916 on its outside. The outside of each sleeve 916 is slidably connected to the inner wall of the hollow rod three 913. The side of each sleeve 916 away from the rotating seat 902 is bolted to a hollow rod four 917. The inner wall of each hollow rod four 917 is slidably connected to the outside of the hollow rod three 913 on the same side. The side of each hollow rod four 917 away from the rotating seat 902 is bolted to the outside of the contact frame 911 on the same side.

[0030] Specifically, after the axis of the cutter ring body 4 is positioned, hydraulic rod 4 (907) is activated. The output end of hydraulic rod 4 (907) extends, thereby pushing the connecting plate 906, which is driven by disc 904, to move on the side of rectangular opening 905 away from the cutter ring body 4. This causes the connecting plate 906 to push the mounting ring 901 to the outermost side of the cutter ring body 4. Hydraulic rod 5 (910) is then activated, pushing the extrusion ring 908 closer to the rotating seat 902. This causes the extrusion ring 908 to lift the rotating seat 902, causing the rotating seat 902 to drive the hollow rod 4 (917) to rotate towards the cutter ring body 4. After the extrusion ring 908 is fully in contact with the mounting ring 901, the rotation... The seat 902 will remain perpendicular to the shaft 7 on the mounting ring 901. The hydraulic rod 907 is activated, and its output end retracts, allowing the hydraulic rod 910 to continue pushing the extrusion ring 908 and the mounting ring 901 toward the cutter ring body 4. After the rotating seat 902 and the edge of the cutter ring body 4 are on the same plane, the motor 914 is activated. The motor 914 drives the screw 915 to rotate, which in turn pushes the hollow rod 917 connected to the sleeve 916 to extend from the hollow rod 913, so that the rubber pad 912 on the contact frame 911 fits against the edge of the cutter ring body 4, thus providing three-point support for the cutter ring body 4.

[0031] In specific application scenarios, the support and stability module 9 is mainly applicable to the support and stability maintenance process. Specifically, the support and stability module 9 uses the mounting ring 901 and the compression ring 908 to keep the rotating seat 902 in a folded state when the shaft rod 7 enters the blade ring body 4, thereby preventing the contact frame 911 from hooking the blade 5 on the blade ring body 4 and ensuring the stability of the device and the blade ring body 4. The rotating seat 902 drives the telescopic hollow rod 917, so that the contact frame 911 can stably support blade ring bodies 4 of different sizes. This allows the blade ring body 4 to maintain a relatively stable state when it is disassembled from the machine body 1, avoiding damage and deformation to the blade ring body 4 and the blade 5 on it.

[0032] Working principle: After the blade ring body 4 in the machine body 1 is pushed out of the machine body 1 by the push rod 3 on the machine body 1, the universal wheel 10 is used to move the mounting frame 6 to a position roughly aligned with the blade ring body 4. The mounting frame 6 is supported by the hydraulic rod 11 and the load-bearing plate 12. The hydraulic rod 807 is activated, and the hydraulic rod 807 pushes the receiving groove 803 to move in the direction of the machine body 1, so that the shaft rod 7 on the fixing part 805 can be inserted into the blade ring body 4. The fixing bolt 829 is rotated to release the locking of the hollow rod 828. Under the elastic force of the spring 826, the hollow rod 828 extends from the hollow rod 825, so that the roller 824 on the support frame 823 can be in contact with the inner part of the blade ring body 4. When the wall is in contact with the hydraulic rod 807, the second hydraulic rod 807 is closed, and the second motor 817 is started. The second motor 817 drives the external gear ring 815, which meshes with the second gear 816, to rotate. This causes the external gear ring 815 to drive the push ring 814 to rotate. During the rotation of the push ring 814, since the shaft 7 is not on the rotation axis of the cutter ring body 4, the support bracket 823, which is in contact with the inner wall of the cutter ring body 4, moves and extends on the hollow rod 825 during its movement in contact with the inner wall of the cutter ring body 4. The displacement sensor 831 on the hollow rod 828 maps the movement trajectory of the hollow rod 828 onto the slide rod 830, so that the displacement sensor 831 records the trajectory of rotation around the shaft 7, and calculates the value of the shaft 7 based on the trajectory. The offset between the axis and the axis of the cutter ring body 4 is determined by starting motor 810, which drives gear 811 and rack 813 to rotate, thereby causing the moving table 809 to move the axis rod 7 laterally on the receiving groove 803. Then, hydraulic rod 804 is activated, causing the axis rod 7 to move vertically, aligning it with the axis of the cutter ring body 4. After alignment, hydraulic rod 822 is activated, its output end pulling the fitting ring 820 into the fitting groove 818, engaging the fitting ring 820 with the rectangular block 819, preventing the push ring 814 from rotating. Finally, the fixing bolt 829 is tightened to prevent the hollow rod 828 from sliding. This completes the positioning of the axis of the cutter ring body 4. Activate hydraulic rod 4 (907). The output end of hydraulic rod 4 (907) extends, thereby pushing the connecting plate 906, which in turn moves the disc 904, onto the rectangular opening 905 to the side of the rectangular opening 905 away from the cutter ring body 4. This causes the connecting plate 906 to push the mounting ring 901 to the outermost side of the cutter ring body 4. Activate hydraulic rod 5 (910). Hydraulic rod 5 (910) pushes the extrusion ring 908 closer to the rotating seat 902, causing the extrusion ring 908 to tilt the rotating seat 902. This causes the rotating seat 902 to drive the hollow rod 4 (917) to rotate towards the cutter ring body 4. After the extrusion ring 908 is fully engaged with the mounting ring 901, the rotating seat 902 will maintain a perpendicular posture to the shaft 7 on the mounting ring 901. Activate hydraulic rod 4 (907).The output end of hydraulic rod 4 907 retracts, allowing hydraulic rod 5 910 to continue pushing the extrusion ring 908 and mounting ring 901 towards the cutter ring body 4. After the rotating seat 902 and the edge of the cutter ring body 4 are on the same plane, motor 3 914 is started. Motor 3 914 drives screw 915 to rotate, causing screw 915 to push hollow rod 4 917, connected to sleeve 916, out from hollow rod 3 913, so that the rubber pad 912 on the contact frame 911 fits against the edge of the cutter ring body 4, thus providing three-point support for the cutter ring body 4. Hydraulic rod 1 804 is then started, lifting the shaft rod 7, thereby disengaging the cutter ring body 4 from the push rod 3 and removing the cutter ring body 4 from the machine body 1.
