Description

Technical Field

[0001] This invention relates to the field of pole processing technology, specifically to a pole reinforcement cage binding device and binding method. Background Technology

[0002] Utility poles primarily serve to support overhead power lines. Common types of poles include wooden poles, concrete poles, and power transmission towers. Concrete poles are made of concrete and reinforcing steel bars or wires. In the production and processing of concrete poles, the required steel bars are pre-cut to a fixed length, then fixed with flanges to form a steel cage, which is then tied with wires to form a steel skeleton.

[0003] Traditional rebar cage binding processes suffer from several drawbacks. Manual operation leads to insufficient mold positioning accuracy, causing structural deformation. High reliance on manpower results in low production efficiency and high labor intensity. The process is poorly adaptable, requiring significant adjustment time when switching between molds of different specifications. The rebar straightening process lacks effective control measures, leaving residual deformation that affects forming quality. Fixed binding methods create blind spots at the top of the mold, leading to incomplete binding in certain areas. Each functional step is separated into an independent process, increasing process complexity and production cycle. Furthermore, the lack of effective operating procedures in low-temperature environments severely impacts production stability and finished product qualification rates under special conditions. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a device and method for binding steel cages for utility poles, which solves the problems of low positioning accuracy, poor efficiency, weak adaptability, straightening defects, binding blind spots, process interruption, and low-temperature failure in traditional manual steel cage binding processes.

The clamping control mechanism is located on the support platform and works with the material conveying calibration cylinder to generate a circumferentially distributed variable pitch traction force; The clamping and straightening mechanism is located on the clamping control mechanism and works with the arc-shaped traction slot and the straight slot to transport and straighten the steel bars to be tied.

[0006] Preferably, the side supports are fixed on the top two sides of the support platform, the opposing guide rings are distributed on both sides of the support platform to form a ring structure with both ends guided, the ring limiting mechanism is set on the support platform, the binding drive mechanism is distributed around the ring limiting mechanism, the clamping control mechanism is set on the side supports and is located on the same mounting axis as the ring limiting mechanism, and the clamping and straightening mechanism consists of multiple sets, which are circumferentially distributed on the clamping control mechanism.

[0007] Preferably, the annular limiting mechanism includes a working tank and an inner cylinder. The working tank is suspended above the support platform, and the inner cylinder is disposed on the working tank. The inner cylinder is provided with circumferentially distributed heating elements, and the sidewall of the inner cylinder is composed of circumferentially distributed blades. The material conveying calibration cylinder is fixed on the side of the working tank near the clamping control mechanism.

[0008] Preferably, the binding drive mechanism includes a support pulley, a rotary drive component, a fixed rotating ring, and an external toothed ring. The support pulley is fixed to the top of the support platform in a rectangular distribution. The fixed rotating ring is distributed and fixed on the surface of the material conveying calibration cylinder and the working tank, and is attached to the surface of the support pulley. The external toothed ring is fixed to the outer wall of the material conveying calibration cylinder.

[0009] Preferably, the clamping control mechanism includes a side ring cover and a stationary plate. The side ring cover is fixed to the top of the side support frame and fits against the input port of the material conveying calibration cylinder. An external toothed ring is rotatably located inside the side ring cover away from the material conveying calibration cylinder. The arc-shaped traction slots are distributed annularly on the external toothed ring. An annular fixing plate is fixed inside the side ring cover near the material conveying calibration cylinder. The straight grooves are distributed annularly on the annular fixing plate. The stationary plate is stationary on the outside of the working tank.

[0010] Preferably, the clamping and straightening mechanism includes a linear carriage, which is simultaneously embedded in the corresponding arc-shaped traction slot and the straight slot through a set clamping structure. The linear carriage has linearly distributed conveying guide rollers that rotate inside, and the outer surface of the conveying guide rollers is provided with a biting groove. The inner side of the linear carriage is provided with a calibration side plate that rotates outward.

[0011] Preferably, the rotary drive is fixed on the support platform, and a drive gear is fixed at the output end of the rotary drive, while an external gear ring meshes with the key end of the drive gear.

[0012] Preferably, the side wall of the side-mounted ring cover has a guide gear that rotates and meshes with the outer teeth of the outer toothed ring.

[0013] Preferably, the calibration side plate and the linear carriage side wall are fixed with a docking clip, and are connected by a reset spring.

[0014] Preferably, a binding method for a pole reinforcement cage binding device includes the following steps: S1: Equipment Preparation and Reinforcement Insertion The main body of the equipment consists of a support platform and a side support frame. Opposing guide rings guide the cylindrical binding mold to be embedded and stationary. A ring-shaped limiting mechanism is set on the support platform, which forms a binding space inside. The clamping control mechanism is located on the side support frame, which has multiple clamping and straightening mechanisms distributed around its circumference. The reinforcing bars are introduced through the clamping and straightening mechanisms, conveyed by the conveying guide rollers, and straightened by the side plate to make the reinforcing bars fit against the surface of the binding mold, ready for binding. S2: Binding Start and Rotation Drive The binding drive mechanism is located on the support platform and includes a support pulley, a rotary drive component, etc. When the rotary drive component is activated, it drives the material conveying calibration cylinder to rotate through the drive gear and the external gear ring, thereby causing the working tank and the annular limiting mechanism to rotate as a whole and change the internal angle. S3: Clamping mechanism linkage and rebar guidance The rotation of the ring-shaped limiting mechanism is transmitted to the clamping control mechanism. The rotation of the material conveying and straightening cylinder drives the outer toothed ring to rotate. Through the cooperation of the arc-shaped traction slot and the straight slot, the linear carriage moves radially, thereby adjusting the position of the clamping and straightening mechanism. Multiple clamping and straightening mechanisms change synchronously, guiding the steel bars to different contact areas of the binding mold. S4: Continuous binding and finished product formation The ring-shaped limiting mechanism rotates continuously, while the clamping and straightening mechanism continuously feeds and straightens the reinforcing bars, guiding them to the free area on the mold surface. As the rotation progresses, the binding operation gradually covers the entire circumference of the mold until all the reinforcing bars are arranged and fixed as required, forming a complete finished pole reinforcing cage.

[0015] This invention provides a device and method for tying reinforcing cages for utility poles. It offers the following advantages: 1. This invention features high-precision spatial positioning: the working tank of the annular limiting mechanism and the inner cylinder form a closed binding operation space, constraining the radial displacement of the reinforcing bars through physical boundaries. The material conveying and calibrating cylinder, serving as the reinforcing bar inlet channel, precisely aligns with the side-mounted ring cover of the clamping control mechanism, ensuring that the reinforcing bars enter the operation space vertically along the axial direction. The opposing guide ring provides coaxial positioning of both ends of the binding mold, eliminating the sway error of the mold during the binding process and controlling the forming accuracy of the reinforcing cage to the millimeter level.

[0016] 2. This invention features dynamic synchronous driving: the rotating drive component of the binding drive mechanism meshes with an external gear ring via a drive gear, converting single-point power into overall rotation of the ring-shaped limiting mechanism. The supporting pulley and the fixed rotating ring form a rolling support system, reducing rotational friction resistance. This design enables working tanks with diameters exceeding one meter to achieve uniform rotation under low-power drive, synchronously driving the circumferential winding action of the internal reinforcing bars.

[0017] 3. This invention features adaptive clamping control: the clamping control mechanism, through the meshing transmission between the external gear ring and the guide gear, converts the rotational motion of the annular limiting mechanism into the displacement of the arc-shaped traction slot. Under the radial constraint of the straight slot, the linear carriage converts the arc-shaped displacement into precise radial movement of the clamping and straightening mechanism. This linkage mechanism enables the clamping and straightening mechanism to synchronously adjust the spacing in real time according to changes in the mold diameter.

[0018] 4. The present invention has a continuous straightening and conveying effect: the interlocking grooves on the surface of the conveying guide rollers form a continuous friction drive on the steel bars, the linearly distributed group of guide rollers eliminates local bending of the steel bars, the alignment side plate applies constant lateral pressure through the reset snap ring, and three-dimensional straightening is implemented in the movement of the steel bars. The docking clamp limits the swing angle of the alignment side plate to ensure the optimal correction angle between the straightening force direction and the steel bar axis.

[0019] 5. This invention has a dead-angle binding coverage effect: the rotation of the ring limiting mechanism and the radial adjustment of the clamping and straightening mechanism form a compound motion trajectory. When the working tank rotates, the outer toothed ring drives the clamping and straightening mechanism to move radially, so that the guide point of the steel bar is always aligned with the unbound area of ​​the mold. This dynamic adjustment realizes the spiral progressive laying of the steel bar on the surface of the mold, completely eliminating the binding blind spots in the traditional process.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see the appendix Figure 1 -Appendix Figure 3 This invention provides a device for binding rebar cages for utility poles, comprising: a support platform 1 and side supports 2, used for fixing and bearing the structure of the utility pole rebar cage binding device. The side supports 2 are fixed on both sides of the top of the support platform 1. The support platform 1 forms the basic support plane of the device. The side supports 2 provide rigid vertical support on both sides of the top of the support platform 1. The support platform 1 and the side supports 2 together ensure the stability of the overall structure of the device, provide the necessary static support foundation for other moving mechanisms, resist various loads and torques generated during the binding operation, and ensure the overall geometric accuracy and positional stability of the device during operation. Please see the appendix Figure 1 -Appendix Figure 3 The opposing guide ring 3 is located on the support platform 1 and is used to support and guide the linear displacement of the pole. The opposing guide ring 3 is distributed on both sides of the support platform 1, forming a ring structure with both ends guided. The opposing guide ring 3 is distributed at the two side edges of the support platform 1. The opposing guide ring 3 forms a pair of coaxial and spaced ring guide structures. The inner ring surface of the opposing guide ring 3 precisely defines the axial position of the cylindrical binding mold. The binding mold achieves precise centering and axial constraint through the inner hole of the opposing guide ring 3, ensuring that the mold remains stationary during the binding process. Its axis coincides with the rotation axis of the equipment, providing a basis for the precise wrapping binding of the reinforcing bars. Please see the appendix Figure 4 -Appendix Figure 6The annular limiting mechanism 4 is located on the support platform 1 and is used to form the working space for tying the rebar cage of the pole. The annular limiting mechanism 4 is set on the support platform 1 and surrounds the tying mold. The working tank 41 of the annular limiting mechanism 4 defines the annular tying working space above the support platform 1. The inner cylinder 42 is installed on the working tank 41. Its circumferentially distributed blade structure allows heat transfer or airflow to pass through. The material conveying and calibration cylinder 43 is fixed on one side of the working tank 41 and serves as a transition channel for the rebar to enter the tying area. The annular limiting mechanism 4 defines and constrains the specific three-dimensional spatial range in which the rebar cage tying operation occurs. Please see the appendix Figure 4 -Appendix Figure 6 The annular limiting mechanism 4 includes a working tank 41 and an inner cylinder 42. The working tank 41 is suspended above the support platform 1, and the inner cylinder 42 is set on the working tank 41. The inner cylinder 42 is provided with circumferentially distributed heating elements, and the side wall of the inner cylinder 42 is composed of circumferentially distributed blades. The material conveying and calibrating cylinder 43 is fixed on the side of the working tank 41 near the clamping control mechanism 6. The working tank 41 serves as the main outer shell of the annular limiting mechanism 4, and the inner cylinder 42 is set inside the working tank 41. Its built-in circumferential heating elements can regulate the temperature of the binding operation space. The side wall of the inner cylinder 42 is composed of breathable blades, allowing environmental interaction. The material conveying and calibrating cylinder 43 is fixed at a specific lateral position of the working tank 41, and its internal channel is used to guide the reinforcing bars to enter the binding space inside the annular limiting mechanism 4 in an orderly manner from the direction of the clamping control mechanism 6.

[0024] Please see the appendix Figure 3 -Appendix Figure 5 The binding drive mechanism 5 is located on the support platform 1 and works with the working tank 41 and the material conveying and calibration cylinder 43 to drive the pole rebar cage binding device to rotate, so as to drive the rebar to wrap around the pole mold. The binding drive mechanism 5 is distributed around the annular limiting mechanism 4. The binding drive mechanism 5 is set on the support platform 1 and surrounds the annular limiting mechanism 4. The core function of the binding drive mechanism 5 is to drive the annular limiting mechanism 4 to rotate around its axis. This rotational movement forces the rebar to spiral or circumferentially wrap around the stationary binding mold, so as to realize the positioning and initial fixation of the rebar on the mold surface and provide dynamic wrapping force for subsequent binding. Please see the appendix Figure 3 -Appendix Figure 5The binding drive mechanism 5 includes a support pulley 51, a rotary drive component 52, a fixed rotating ring 53, and an external toothed ring 55. The support pulley 51 is fixed to the top of the support platform 1 in a rectangular arrangement. The fixed rotating ring 53 is distributed and fixed on the surfaces of the material conveying calibration cylinder 43 and the working tank 41, and fits against the surface of the support pulley 51. The external toothed ring 55 is fixed to the outer wall of the material conveying calibration cylinder 43. The support pulley 51 is fixed on the support platform 1 to provide a low-friction support point. The fixed rotating ring 53 is fixed to the material conveying... The calibration cylinder 43 and the outer surface of the working tank 41 are aligned and the rolling contact is made with the support pulley 51. The external toothed ring 55 is fixed on the outer wall of the material conveying calibration cylinder 43. The rotary drive component 52 outputs rotational power. The drive gear 54 is fixed at the output end of the rotary drive component 52 and meshes with the external toothed ring 55. The rotary drive component 52 drives the drive gear 54 to rotate. Through gear meshing, the external toothed ring 55 is driven to rotate, thereby driving the entire annular limiting mechanism 4 to rotate around the axis. The fixed rotating ring 53 rolls smoothly on the support pulley 51. Please see the appendix Figure 5 The rotary drive component 52 is fixed on the support platform 1, and the output end of the rotary drive component 52 is fixed with a drive gear 54. The external gear ring 55 meshes with the key end of the drive gear 54. The rotary drive component 52 is started as a power source. The output shaft of the rotary drive component 52 directly drives the drive gear 54 to rotate synchronously. The teeth of the drive gear 54 mesh tightly with the tooth grooves of the external gear ring 55. The rotational torque of the drive gear 54 is transmitted to the external gear ring 55 through the meshing action of the teeth. The external gear ring 55 converts the received rotational torque into its own rotational motion around the axis of the equipment. This rotational motion is the direct power source for driving the ring-shaped limiting mechanism 4 to rotate.

[0025] Please see the appendix Figure 4 -Appendix Figure 9 The clamping control mechanism 6 is located on the support platform 2 and works with the feeding and straightening cylinder 43 to generate a circumferentially distributed variable pitch traction force. The clamping control mechanism 6 is set on the side support 2 and is on the same mounting axis as the annular limiting mechanism 4. The clamping control mechanism 6 is set on the side support 2 and its axis coincides with the axis of the annular limiting mechanism 4. The clamping control mechanism 6 receives the rotational motion input from the binding drive mechanism 5. The core function of the clamping control mechanism 6 is to generate a circumferentially distributed and synchronously adjustable radial traction force. This traction force precisely controls the radial position of multiple clamping and straightening mechanisms 7, enabling them to collectively and synchronously contract or expand according to the diameter change of the binding mold. Please see the appendix Figure 6 -Appendix Figure 9The clamping control mechanism 6 includes a side ring cover 61 and a stationary plate 67. The side ring cover 61 is fixed to the top of the side support frame 2 and is attached to the input port of the material conveying calibration cylinder 43. Inside the side ring cover 61, away from the material conveying calibration cylinder 43, there is an external toothed ring 62 that rotates. Arc-shaped traction slots 63 are distributed in a ring on the external toothed ring 62. Inside the side ring cover 61, near the material conveying calibration cylinder 43, there is an annular fixing plate 65 that is fixed. Straight grooves 66 are distributed in a ring on the annular fixing plate 65. The stationary plate 67 is stationary on the outside of the working tank 41. The side-mounted ring cover 61 is fixed to the top of the side support 2 and fits against the inlet of the material conveying calibration cylinder 43. The external toothed ring 62 is rotatable inside the side-mounted ring cover 61 away from the material conveying calibration cylinder 43. The arc-shaped traction slots 63 are distributed in a ring on the external toothed ring 62. The guide gear 64 is rotatably installed on the side wall of the side-mounted ring cover 61 and meshes with the external toothed ring 62. The annular fixing plate 65 is fixed inside the side-mounted ring cover 61 near the material conveying calibration cylinder 43. The straight grooves 66 are distributed in a ring on the annular fixing plate 65 to provide radial guidance. The stationary plate 67 remains stationary. Please see the appendix Figure 9 The side wall of the side-mounted ring cover 61 has a rotatable guide gear 64. The guide gear 64 meshes with the outer tooth key of the outer tooth ring 62. The rotation of the ring-shaped limiting mechanism 4 causes the side-mounted ring cover 61, which is in contact with its inlet, to generate a relative motion tendency. Since the side-mounted ring cover 61 is fixed, the guide gear 64 on its side wall is driven to rotate. The rotation of the guide gear 64 acts on the outer tooth ring 62 that meshes with it. The guide gear 64 drives the outer tooth ring 62 to rotate around the equipment axis inside the side-mounted ring cover 61. The rotation of the outer tooth ring 62 is the power source for the displacement of the arc-shaped traction slot 63 on it.

[0026] Please see the appendix Figure 4 -Appendix Figure 10 The clamping and straightening mechanism 7 is located on the clamping control mechanism 6. It works with the arc-shaped traction slot 63 and the straight slot 66 to transport and straighten the steel bars to be tied. There are multiple sets of clamping and straightening mechanisms 7, which are circumferentially distributed on the clamping control mechanism 6. The core function of the clamping and straightening mechanism 7 is to perform two tasks: first, to continuously and stably transport the steel bars to be tied to the tying area through the rotation of its internal conveying guide roller 72; second, to perform necessary straightening treatment on the steel bars during transport through its structural design, to eliminate bending or twisting, and to ensure that the steel bars enter the tying operation space in a straight state and accurately fit the surface of the tying mold. Please see the appendix Figure 4 -Appendix Figure 10The clamping and straightening mechanism 7 includes a linear carriage 71. The linear carriage 71 is simultaneously embedded in the corresponding arc-shaped traction slot 63 and straight slot 66 through a set clamping structure. Linearly distributed conveying guide rollers 72 rotate inside the linear carriage 71. The outer surface of the conveying guide rollers 72 is provided with a biting groove. The inner side of the linear carriage 71 is provided with a calibration side plate 73 that rotates outward. The linear carriage 71 constitutes the main body of the mechanism. The linear carriage 71 is simultaneously embedded in the arc-shaped traction slot 63 and straight slot 66 through its clamping structure. The conveying guide rollers 72 are linearly arranged and rotate inside the linear carriage 71. The biting groove on its surface provides driving friction force for the reinforcing bar. The calibration side plate 73 is set inside the linear carriage 71 and can rotate outward. The docking clamp 74 connects the calibration side plate 73 and the side wall of the linear carriage 71. The two are maintained by a reset spring to maintain the elastic clamping force of the calibration side plate 73 on the reinforcing bar. Please see the appendix Figure 9 -Appendix Figure 10 The calibration side plate 73 is fixed to the side wall of the linear carriage 71 with a docking clip 74 and connected by a reset snap spring. The calibration side plate 73 is located on the side of the necessary path of the inner reinforcing bar of the linear carriage 71. The calibration side plate 73 can rotate outward at a certain angle around its installation point. The docking clip 74 restricts the rotation range of the calibration side plate 73. The reset snap spring provides the elastic force for the calibration side plate 73 to reset inward. When the reinforcing bar passes through the linear carriage 71, the side of the reinforcing bar contacts the calibration side plate 73. Under the action of the reset snap spring, the calibration side plate 73 continuously applies a lateral straightening force to the reinforcing bar, forcing the reinforcing bar to move in a straight line and correcting its bending deformation.

[0027] Based on the above technical solution, embodiments of the present invention also provide a binding method for a pole reinforcement cage binding device, comprising the following: S1: Equipment Preparation and Reinforcement Insertion The support platform 1 and the side support frame 2 constitute the main support structure of the equipment. The side support frame 2 is located on both sides of the top of the support platform 1. Opposing guide rings 3 are distributed on both sides of the support platform 1. The cylindrical binding mold is guided by the opposing guide rings 3 and embedded into the opposing guide rings 3, and remains stationary during the binding process. The annular limiting mechanism 4 is set on the support platform 1. The working tank 41 is suspended above the support platform 1. The inner cylinder 42 is set on the working tank 41. The material conveying calibration cylinder 43 is fixed on the side of the working tank 41 near the clamping control mechanism 6. The space inside the annular limiting mechanism 4 forms the binding operation space for the steel cage. The clamping control mechanism 6 is located around the stationary binding mold, and is mounted on the side support 2. The side ring cover 61 is fixed to the top of the side support 2 and fits against the input port of the material conveying calibration cylinder 43. The stationary plate 67 is stationary on the outside of the working tank 41. The annular fixing plate 65 is fixed inside the side ring cover 61 near the material conveying calibration cylinder 43. The straight groove 66 is distributed in a ring on the annular fixing plate 65. The external toothed ring 62 rotates inside the side ring cover 61 away from the material conveying calibration cylinder 43. The arc-shaped traction slot 63 is distributed in a ring on the external toothed ring 62. The guide gear 64 rotates on the side ring cover 67. 1. A side wall, and meshes with the outer tooth key of the outer toothed ring 62. Multiple clamping and straightening mechanisms 7 are circumferentially distributed on the clamping control mechanism 6. Each clamping and straightening mechanism 7 includes a linear carriage 71. The linear carriage 71 is embedded in the corresponding arc-shaped traction slot 63 and straight groove 66 through its clamping shaft structure. Linearly distributed conveying guide rollers 72 rotate inside the linear carriage 71. The outer surface of the conveying guide rollers 72 is provided with a biting groove. The inner side of the linear carriage 71 is provided with a calibration side plate 73 that rotates outward. The calibration side plate 73 and the side wall of the linear carriage 71 are fixed with a docking clamp 74, and the calibration side plate 73 and the linear carriage 71 are also connected. The components 1 are connected by a reset snap ring. The clamping control mechanism 6 drives the clamping and straightening mechanisms 7 installed at its multiple output ends to simultaneously retract or expand inward along the axis. The clamping and straightening mechanisms 7 change their own positions according to the size of the binding mold. Multiple circumferentially distributed clamping and straightening mechanisms 7 form an independent and ring-shaped steel bar guiding structure. The steel bars to be bound are introduced through the clamping and straightening mechanisms 7. The rotating action of the conveying guide roller 72 conveys the steel bars. The alignment side plate 73 straightens the steel bars. The steel bars are guided to the surface of the binding mold and are fixed to the surface of the binding mold by the positioning action of the clamping and straightening mechanisms 7, ready for binding. S2: Binding Start and Rotation Drive The binding drive mechanism 5 is distributed around the annular limiting mechanism 4 and is set on the support platform 1. The binding drive mechanism 5 includes a support pulley 51, a rotary drive component 52, a fixed rotating ring 53, a drive gear 54, and an external toothed ring 55. The support pulley 51 is fixed to the top of the support platform 1 in a rectangular arrangement. The fixed rotating ring 53 is distributed and fixed on the surface of the material conveying calibration cylinder 43 and the working tank 41, and is attached to the surface of the support pulley 51. The external toothed ring 55 is fixed to the outer wall of the material conveying calibration cylinder 43. The rotary drive component 52 is fixed on the support platform 1. When the rotary drive component 52 is activated, its output end rotates... The drive gear 54 is fixed at the output end of the rotary drive component 52 and rotates together with the output end. The external gear ring 55 meshes with the key end of the drive gear 54. The rotation of the drive gear 54 drives the external gear ring 55 to rotate. The rotation of the external gear ring 55 drives the material conveying calibration cylinder 43 to rotate. The rotation of the material conveying calibration cylinder 43 drives the working tank 41 to rotate. The rotation of the working tank 41 drives the fixed rotating ring 53 to roll on the surface of the support pulley 51, realizing the overall rotational movement of the annular limiting mechanism 4. The annular limiting mechanism 4 is driven to rotate by the binding drive mechanism 5, changing the internal angle of the annular limiting mechanism 4. S3: Clamping mechanism linkage and rebar guidance The rotational motion of the annular limiting mechanism 4 simultaneously acts on the clamping control mechanism 6. The feeding and straightening cylinder 43 is part of the annular limiting mechanism 4, and its rotation is directly transmitted to the side-mounted annular cover 61 that is in contact with it. The side-mounted annular cover 61 is fixed on the side support 2 and does not rotate itself. The rotating external gear ring 62 inside the side-mounted annular cover 61 generates relative motion with the rotation of the feeding and straightening cylinder 43. The guide gear 64 meshes with the outer gear key of the external gear ring 62. When the feeding and straightening cylinder 43 rotates, the guide gear 64 rotates on the side wall of the stationary side-mounted annular cover 61. The rotation of the guide gear 64 drives the external gear ring 62 that meshes with it to rotate inside the side-mounted annular cover 61. The rotation of the external gear ring 62 drives the arc-shaped traction slot 63 on it to move. The linear carriage 71 of each clamping and straightening mechanism 7 is simultaneously embedded in the arc through the clamping shaft structure. Inside the arc-shaped traction slot 63 and the straight groove 66, the annular fixing plate 65 is fixed on the side ring cover 61. The straight groove 66 on it provides radial guidance. The arc-shaped traction slot 63 is displaced when the external toothed ring 62 rotates. The displacement of the arc-shaped traction slot 63 acts on the linear carriage 71 through the clamping shaft structure. The straight groove 66 constrains the movement direction of the linear carriage 71. The displacement of the arc-shaped traction slot 63 drives the linear carriage 71 to move along the guide path of the straight groove 66. The movement of the linear carriage 71 changes the distance between the clamping and straightening mechanism 7 and the axis of the binding mold. Multiple clamping and straightening mechanisms 7 change their positions synchronously with the rotation of the external toothed ring 62. The clamping control mechanism 6 rotates along the side support 2 as the annular limiting mechanism 4 rotates. Multiple clamping and straightening mechanisms 7 change their contact area with the binding mold. S4: Continuous binding and finished product formation During the continuous rotation of the annular limiting mechanism 4, the binding operation is carried out within the internal space of the annular limiting mechanism 4. The clamping and straightening mechanism 7 continuously conveys and straightens the reinforcing bars. The reinforcing bars are stably conveyed through the meshing groove of the conveying guide roller 72. The alignment side plate 73 ensures that the reinforcing bars are straight. The reinforcing bars are guided to the current contact area on the surface of the binding mold. With the rotation of the annular limiting mechanism 4 and the linkage of the clamping control mechanism 6, the positions of multiple clamping and straightening mechanisms 7 change dynamically. The clamping and straightening mechanism 7 guides the reinforcing bars to be assembled to the empty area of ​​the binding mold. The previously bound area is moved away during rotation, and the new empty area is moved into the working area of ​​the clamping and straightening mechanism 7 during rotation. Within the range, the reinforcing bars are continuously guided to these newly emerging empty mold surface areas. The reinforcing bars are attached and fixed on the mold surface and tied. The rotation angle of the annular limiting mechanism 4 is continuously changed, and the contact area between the clamping and straightening mechanism 7 and the mold is continuously changed. The reinforcing bars are continuously guided to the empty, waiting-to-be-tied positions on the circumference of the mold. The tying operation is gradually advanced on the circumference of the mold, covering the entire circumference. This process is repeated until the reinforcing bars cover the entire preset surface area of ​​the tying mold. All reinforcing bars are arranged and fixed on the mold surface as required. Finally, a complete and compliant pole reinforcing cage finished structure is formed on the surface of the tying mold.
