Description

Technical Field

[0001] This invention relates to the field of turning machine technology, and more particularly to an adjustable turning machine adaptable to various terrains. Background Technology

[0002] In automated conveying systems, turning conveyors are key equipment for achieving smooth material turning and conveying. They typically consist of an arc-shaped frame, conical rollers, a turning belt, a drive system, and a tensioning device. Utilizing the speed difference between the inner and outer diameters of the conical rollers or the differential speed principle of the chain plates, they enable the conveyed items to continuously and smoothly change direction in the horizontal plane. Turning conveyors can effectively connect straight conveyor sections in different directions, reduce transfer points, improve overall conveying efficiency, and are widely integrated into various fixed and mobile conveyor lines.

[0003] With the rapid development of logistics warehousing, express sorting, food and beverage, airport baggage handling, and industrial automation, the application scenarios of turning machines are becoming increasingly diversified and complex. In actual engineering, due to limitations imposed by building columns, equipment layout, clearance height, and process flow direction, conveyor lines often require turning machines with different turning radii and angles, such as 600 mm, 800 mm, and 1000 mm curvature radii, and different wrap angles of 30 degrees, 45 degrees, 90 degrees, and even 180 degrees. In some temporary deployment or mobile operation scenarios, such as bulk cargo loading, disaster relief material transportation, and mobile loading, the conveying path also needs to be dynamically adjusted according to the vehicle position and stacking height, placing flexible and varied requirements on the bending shape, footprint, and height adaptability of the turning machine.

[0004] To address these needs, adjustable turning machines with a certain degree of adjustability have emerged in the industry. However, existing adjustable turning machines still have significant limitations in their bending structures. For example, in common designs, the radius of curvature of the curved frame of the bending conveyor section is fixed after production and assembly. That is, the bending structure is solidified with a specific curvature after leaving the factory. In reality, only the height of the support legs or the directional angle of the inlet and outlet ends can often be adjusted, while the curvature of the turning section itself cannot be changed. This means that when the site requires a smaller turning radius due to obstacles or changes in the passageway, or when a smoother, larger radius is needed to transport fragile items, such turning machines cannot adapt. The only solution is to replace the entire machine, resulting in increased costs and project delays. Although some adjustable solutions using segmented assembly can discretely change the turning angle, the radius of curvature still depends on the preset curved module, making it difficult to achieve continuous, stepless curvature adjustment. This makes it impossible to truly meet the precise requirements of narrow, irregular, or non-standard spaces for conveying curved shapes. Therefore, developing an adjustable turning machine with a flexible bending radius that can truly adapt to various site conditions has become a technical problem that urgently needs to be solved in the industry. Summary of the Invention

[0005] The purpose of this invention is to provide an adjustable turning machine that can adapt to various sites, thereby solving the problems in the prior art.

[0006] Specifically: An adjustable turning machine adaptable to various sites includes multiple sets of fixed roller conveyors and multiple sets of movable roller conveyors, which are distributed in a crisscross pattern. The fixed roller conveyors are supported by a support frame. The movable roller conveyors include multiple sets of unit roller components, which are assembled side by side in sequence. Each unit roller component includes a roller structure and two angle adjustment structures: the roller structure is used to forwardly convey objects; the two angle adjustment structures are assembled at both ends of the roller structure; the angle adjustment structures are used to drive the roller structure to rotate, allowing for adjustment of the multiple sets of unit roller components to different arc angles. When adjustments are needed due to changes in obstacles and passageways, the movable roller conveyor is activated. This conveyor utilizes two angle adjustment structures on one or more sets of unit roller components. These angle adjustment structures drive relative rotation between adjacent roller structures, allowing for different curvature adjustments of multiple sets of unit roller components. This enables the movable roller conveyor to adjust its own bending, allowing multiple fixed roller conveyors to work in conjunction with multiple movable roller conveyors. This allows for different configurations of a single turning machine to adapt to various terrains. The angle adjustment structures provide continuous, stepless curvature adjustment, ensuring the movable roller conveyor truly meets the precise requirements of narrow, irregularly shaped, or unpredictable spaces for conveying curved shapes.

[0007] In a further optional embodiment, the angle adjustment structure includes:

[0008] An angle adjustment body is assembled at one end of the roller structure and is rotatably assembled with the roller structure; the angle adjustment body is located between the ends of two adjacent roller structures and is used to drive the roller structure to rotate, so as to achieve adjustment of the different arcs of multiple sets of unit roller components.

[0009] The power transmission component is rotatably mounted on the angle adjustment body and is connected to the drum structure via power transmission; the power transmission component is used to connect two adjacent drum structures together via power transmission.

[0010] In a further optional embodiment, the angle adjustment body includes:

[0011] An internal support platform with a cavity;

[0012] A U-shaped hinged plate is fixed on one side of the support platform, and a roller structure is set on the other side of the support platform.

[0013] A rotating plate is rotatably mounted on the U-shaped hinge plate via a positioning shaft;

[0014] Hydraulic telescopic rod A is fixed to the end of the rotating plate away from the U-shaped hinge plate; the hydraulic telescopic rod A is fixed to a support platform on an adjacent unit roller component;

[0015] The trough is located on the side wall of the support platform.

[0016] In a further optional embodiment, the power transmission component includes:

[0017] A rotating shaft B is rotatably mounted on a support platform; and a positioning hole is provided on the support platform to accommodate the rotating shaft B.

[0018] A bearing ring is fitted and fixed on the rotating shaft B; the bearing ring is located inside the positioning hole and is used for the rotating shaft B to rotate and be inserted into it for assembly.

[0019] A conical tooth A is fitted and fixed on the rotating shaft B and located inside the cavity of the support platform; the cylindrical center line of the conical tooth A and the cylindrical center line of the rotating shaft B are on the same straight line.

[0020] Conical tooth B is located inside the cavity of the support platform; the conical tooth B meshes with the conical tooth A;

[0021] A rotating shaft C is fixed on a conical tooth B; the rotating shaft C and the conical tooth B are on the same straight line; the rotating shaft C rotates through the support platform and extends out of the support platform and is fixed on the roller structure; the roller structure and the rotating shaft C are on the same straight line.

[0022] In a further optional embodiment, the power transmission component also includes:

[0023] A telescopic pivot is attached to the end of pivot B; the telescopic pivot is located outside the support platform.

[0024] A universal joint is added to a telescopic shaft and is used to connect to the power transmission of the telescopic shaft.

[0025] A rotating shaft A is mounted on the universal joint; the rotating shaft A is rotatably mounted on a support platform on another adjacent unit roller and is fixed together with the rotating shaft B.

[0026] In a further optional embodiment, the telescopic shaft includes an insert shaft and a sleeve. The insert shaft is movably inserted into the sleeve. The insert shaft is provided with a protrusion to prevent the insert shaft from sliding and rotating inside the sleeve. A hydraulic telescopic rod C is fixed inside the sleeve. The hydraulic telescopic rod C is used to adjust the length of the telescopic shaft by adjusting the insertion depth of the insert shaft in the sleeve.

[0027] When adjustments are needed due to changes in obstacles and passageways, the movable roller conveyor is activated. This conveyor utilizes two angle adjustment structures on one or more sets of unit roller components. The two corresponding angle adjustment structures at both ends of the roller structure activate hydraulic telescopic rod A, causing relative rotation between adjacent roller structures. Subsequently, hydraulic telescopic rod C is activated. By adjusting the insertion depth of the through-shaft in the sleeve, the length of the telescopic shaft is adjusted to coordinate with the relative rotation of the two roller structures and ensure stable power transmission. This allows multiple sets of unit roller components to be arranged in different arcs, completing the self-bending adjustment of the movable roller conveyor. This enables multiple fixed roller conveyors to work in conjunction with multiple movable roller conveyors, allowing for different configurations of a single turning machine to adapt to various terrains. The angle adjustment structure provides continuous, stepless arc adjustment, ensuring the movable roller conveyor truly meets the precise requirements of narrow, irregularly shaped, or unpredictable spaces for conveying curved shapes.

[0028] In a further optional embodiment, the roller structure includes a roller, and the roller includes:

[0029] The rotating shaft D is assembled between two angle adjustment structures;

[0030] A telescopic cylinder is fitted outside the rotating shaft D;

[0031] A rubber sleeve is fitted over the outside of the telescopic cylinder;

[0032] Both drive columns are slidably sleeved on the rotating shaft D.

[0033] In a further optional embodiment, the rotating shaft D includes:

[0034] Two rotating shafts are respectively mounted on two angle adjustment structures;

[0035] A connecting shaft connects the two rotating shafts; the connecting shaft and the two rotating shafts are arranged in a straight line.

[0036] Two mounting slots are respectively opened on the two rotating shafts;

[0037] Two hydraulic telescopic rods B are respectively installed inside the two mounting slots; one end of each hydraulic telescopic rod B is fixed to the end of the mounting slot, and the other end is fixed to the drive column; the hydraulic telescopic rods B are used to control the sliding position of the drive column on the rotating shaft by extending and retracting.

[0038] In a further optional embodiment, the telescopic cylinder includes a telescopic cylinder body, which includes multiple support plates arranged in a circular array around the rotating shaft D; a rotating connector is fixed at the center of the support plate, and the support plate is rotatably mounted on the connecting shaft through the rotating connector; the end of the support plate abuts against the drive column.

[0039] In a further alternative embodiment, the drive column is frustum-shaped; the rotating connector includes a U-shaped connecting plate and a positioning plate, with the positioning plate rotatably mounted on the U-shaped connecting plate.

[0040] Compared with the prior art, the present invention provides an adjustable turning machine adaptable to various sites, which has the following features:

[0041] 1. When adjustments are needed due to changes in obstacles and passageways, the movable roller conveyor is activated. The movable roller conveyor uses two angle adjustment structures on one or more sets of unit roller components. The angle adjustment structures drive the relative rotation of two adjacent roller structures, allowing for different curvature adjustments of multiple sets of unit roller components. This completes the self-bending adjustment of the movable roller conveyor, enabling multiple fixed roller conveyors to work together with multiple movable roller conveyors to achieve different configurations of a single turning machine to adapt to various sites. The angle adjustment structure provides continuous and stepless curvature adjustment, allowing the movable roller conveyor to truly meet the precise requirements of narrow, irregular, or non-standard spaces for conveying curved shapes.

[0042] 2. After multiple roller structures rotate relative to each other and multiple sets of unit roller components are arranged with different arcs to complete the self-bending adjustment of the movable roller line, the hydraulic telescopic rod B at one end of the rotating shaft D is activated. The hydraulic telescopic rod B pulls the drive column at this end against the support plate. Since the drive column is truncated cone-shaped, it can make the support plate flip around the rotating connector. During this process, the hydraulic telescopic rod B at the other end of the rotating shaft D will cooperate to push out the drive column at the other end of the rotating shaft D to cooperate with the flipping of the support plate. This allows the telescopic cylinder to change to truncated cone shapes of different sizes to accommodate the different arc arrangements of multiple sets of unit roller components and the different bending arcs of the movable roller line itself, reducing the gap between adjacent rollers and improving the adaptability of the movable roller line.

[0043] 3. The angle adjustment structure drives the adjacent roller structure to rotate relative to each other through the hydraulic telescopic rod A, causing multiple sets of unit roller components to continuously and infinitely adjust their arc. This, combined with the hydraulic telescopic rod B pulling the frustum-shaped drive column against the support plate and causing it to flip, allows the telescopic cylinder to change into different sizes of frustum shapes to cooperate with each other. While the bending arc of the turning machine is infinitely adjusted, the telescopic cylinder can automatically change its own taper size according to the change of arc, compensating in real time for the end gap caused by the change of the included angle of the axis of the adjacent roller structure. This ensures that the conveying surface always remains in a close fit throughout the entire bending adjustment range, completely eliminating the hidden danger of increased gap after bending in traditional adjustable turning machines, which leads to jamming. This achieves continuous conveying with variable curvature and zero gap.

[0044] 4. The hydraulic telescopic rod C changes the length of the telescopic shaft by adjusting the insertion depth to coordinate with the relative rotation of the two roller structures and to achieve stable power transmission. It works in conjunction with the hydraulic telescopic rods B at both ends of the shaft D to push the frustum-shaped drive column, causing the support plate to flip and change the frustum-shaped size of the telescopic cylinder. After the turning machine adjusts the bending shape, not only does the length of the power transmission component automatically adapt to the new geometric relationship, but the taper of the telescopic cylinder also changes continuously with the change of the bending radius. It accurately matches the difference in the conveyor line speed between the inner and outer sides of the turn, so that the material can achieve smooth pure rolling turning without the need for an additional differential device. This solves the problem of material rubbing and deflection caused by speed difference when turning with variable curvature.

[0045] 5. Multiple sets of fixed roller conveyors work together with multiple sets of movable roller conveyors. Through multiple angle adjustment structures, the movable roller conveyors can complete the overall structure of different shapes and arrangements. The system is combined with the telescopic cylinder through the cooperation of the drive column and support plate to change the taper to reduce the gap. The entire turning machine is no longer limited to a preset single arc path. It can be freely arranged into S-shape, variable curvature arc, or even asymmetrical irregular shape according to the obstacle conditions on site. Moreover, the conveying gap and the speed difference between the inner and outer sides of each bending node are adaptively compensated. This allows complex spatial turning tasks that originally required multiple fixed-angle turning machines to work in relay to be completed by this one machine. It greatly breaks through the dependence of traditional turning machines on regular turning radii and significantly expands the precise adaptability to narrow, irregular and irregular sites.

Detailed Implementation

[0060] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0061] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0062] In one embodiment of the present invention, please refer to Figure 1An adjustable turning machine adaptable to various sites includes multiple sets of fixed roller lines 1 and multiple sets of movable roller lines 3, wherein the multiple sets of fixed roller lines 1 and multiple sets of movable roller lines 3 are distributed in a cross pattern, and the fixed roller lines 1 are supported by a support frame 2.

[0063] Therefore, when the site needs to be adjusted due to changes in obstacles and passages, the movable roller line 3 is activated. The movable roller line 3 is used to adjust its own bending, so that multiple sets of fixed roller lines 1 and multiple sets of movable roller lines 3 can cooperate to achieve different shapes and arrangements of a turning machine to adapt to various sites.

[0064] Please continue reading. Figure 2 and Figure 3 The movable roller conveyor 3 includes multiple sets of unit roller components 31, which are assembled side by side in sequence; each unit roller component 31 includes:

[0065] Roller structure 33 is used to convey objects forward;

[0066] Two angle adjustment structures 32 are assembled at both ends of the roller structure 33; the angle adjustment structures 32 are used to drive the roller structure 33 to rotate, so as to adjust the different arcs of multiple sets of unit roller parts 31.

[0067] Therefore, when the site needs to be adjusted due to changes in obstacles and passageways, the movable roller line 3 is activated. The movable roller line 3 uses one or more sets of unit roller components 31 or two angle adjustment structures 32 on multiple sets of unit roller components 31. The angle adjustment structure 32 drives two adjacent roller structures 33 to rotate relative to each other, so as to adjust the different arc positions of multiple sets of unit roller components 31 and complete the self-bending adjustment of the movable roller line 3. This allows multiple sets of fixed roller lines 1 and multiple sets of movable roller lines 3 to cooperate and achieve different shapes of a turning machine to adapt to various sites. The angle adjustment structure 32 achieves continuous and stepless arc adjustment, so that the movable roller line 3 can truly meet the precise needs of narrow, irregular or irregular spaces for conveying bending shapes.

[0068] In another embodiment of the present invention, please refer to Figures 2-4 The angle adjustment structure 32 includes:

[0069] An angle adjustment body 321 is assembled at one end of the roller structure 33 and is rotatably assembled with the roller structure 33; the angle adjustment body 321 is located between the ends of two adjacent roller structures 33 and is used to drive the roller structure 33 to rotate, so as to adjust the different arcs of multiple sets of unit roller parts 31.

[0070] The power transmission component 322 is rotatably mounted on the angle adjustment body 321 and is power-transmittedly connected to the roller structure 33; the power transmission component 322 is used to power-transmit two adjacent roller structures 33 together.

[0071] Please see Figure 4 and Figure 5 The angle adjustment body 321 includes:

[0072] The support platform 3211 has an internal cavity;

[0073] The U-shaped hinge plate 3213 is fixed on one side of the support platform 3211, and the roller structure 33 is set on the other side of the support platform 3211.

[0074] The rotating plate 3214 is rotatably mounted on the U-shaped hinge plate 3213 via the positioning shaft 3212;

[0075] The hydraulic telescopic rod A3215 is fixed to the end of the rotating plate 3214 away from the U-shaped hinge plate 3213; the hydraulic telescopic rod A3215 is fixed to the support platform 3211 on the adjacent unit roller 31;

[0076] The groove 3216 is formed on the side wall of the support platform 3211.

[0077] Therefore, when the site needs to be adjusted due to changes in obstacles and passageways, the movable roller line 3 is activated. The movable roller line 3 uses two angle adjustment structures 32 on one or more sets of unit roller components 31. The two corresponding angle adjustment structures 32 at both ends of the roller structure 33 activate the hydraulic telescopic rod A3215 to extend and retract, so that the angle adjustment structure 32 drives the two adjacent roller structures 33 to rotate relative to each other. The multiple sets of unit roller components 31 are arranged in different arcs to complete the self-bending adjustment of the movable roller line 3. This allows multiple sets of fixed roller lines 1 and multiple sets of movable roller lines 3 to cooperate, achieving different shapes and arrangements of a single turning machine to adapt to various sites. The angle adjustment structure 32 achieves continuous and stepless arc adjustment, making the movable roller line 3 truly meet the precise requirements of the narrow, irregular, or irregular spaces for conveying bending shapes.

[0078] Please see Figures 4-6 The power transmission component 322 includes:

[0079] A rotating shaft B3226 is rotatably mounted on a support platform 3211; and a positioning hole 3217 is provided on the support platform 3211 to cooperate with the rotating shaft B3226.

[0080] The bearing ring 3224 is sleeved and fixed on the rotating shaft B3226; the bearing ring 3224 is located inside the positioning hole 3217 and is used for the rotating shaft B3226 to rotate and be inserted into it.

[0081] The conical tooth A3225 is sleeved and fixed on the rotating shaft B3226 and located inside the cavity of the support platform 3211; the cylindrical center line of the conical tooth A3225 and the cylindrical center line of the rotating shaft B3226 are on the same straight line;

[0082] The conical tooth B3227 is located inside the cavity of the support platform 3211; the conical tooth B3227 meshes with the conical tooth A3225;

[0083] A rotating shaft C3228 is fixed on a conical tooth B3227; the rotating shaft C3228 and the conical tooth B3227 are on the same straight line; the rotating shaft C3228 rotatably passes through the support platform 3211 and extends out of the support platform 3211 and is fixed on the roller structure 33; the roller structure 33 and the rotating shaft C3228 are on the same straight line.

[0084] Please see Figure 4 and Figure 6 The power transmission component 322 further includes:

[0085] Telescopic pivot 3223 is installed at the end of pivot B3226; the telescopic pivot 3223 is located outside the support platform 3211;

[0086] Universal shaft 3222 is mounted on telescopic shaft 3223 and is used for power transmission connection with telescopic shaft 3223;

[0087] A rotating shaft A3221 is mounted on the universal joint 3222; the rotating shaft A3221 is rotatably mounted on a support platform 3211 on another adjacent unit roller 31 and is fixed together with the rotating shaft B3226.

[0088] Please see Figure 6 The telescopic shaft 3223 includes an insert shaft and a sleeve. The insert shaft is movably inserted into the sleeve. The insert shaft is provided with a protrusion to prevent the insert shaft from sliding and rotating inside the sleeve. A hydraulic telescopic rod C is fixed inside the sleeve. The hydraulic telescopic rod C is used to adjust the length of the telescopic shaft 3223 by adjusting the insertion depth of the insert shaft in the sleeve.

[0089] Therefore, when adjustments are needed due to changes in obstacles and passageways, the movable roller line 3 is activated. The movable roller line 3 uses two angle adjustment structures 32 on one or more sets of unit roller components 31. The two corresponding angle adjustment structures 32 at both ends of the roller structure 33 activate the hydraulic telescopic rod A3215 to extend and retract, so that the angle adjustment structure 32 drives the two adjacent roller structures 33 to rotate relative to each other. Then, the hydraulic telescopic rod C is activated. The hydraulic telescopic rod C adjusts the length of the telescopic shaft 3223 by adjusting the insertion depth of the through-shaft in the sleeve, so as to cooperate with the relative rotation of the two roller structures 33 and to carry out stable power transmission. This allows the multiple sets of unit roller components 31 to adjust to different arc angles, completing the self-bending adjustment of the movable roller line 3. This enables multiple sets of fixed roller lines 1 and multiple sets of movable roller lines 3 to cooperate, achieving different shape arrangements of a single turning machine to adapt to various sites. The angle adjustment structure 32 achieves continuous and stepless arc adjustment, making the movable roller line 3 truly meet the precise needs of narrow, irregular, or irregular spaces for conveying curved shapes.

[0090] In another embodiment of the present invention, please refer to Figure 7 The roller structure 33 includes a roller 331, and the roller 331 includes:

[0091] The rotating shaft D335 is mounted between two angle adjustment structures 32 (specifically, the power transmission connection of the rotating shaft D335 is on the rotating shaft C3228).

[0092] Telescopic cylinder 333 is sleeved outside the rotating shaft D335;

[0093] A rubber sleeve 332 is fitted over the outside of the telescopic cylinder 333;

[0094] Both drive columns 334 are slidably sleeved on the rotating shaft D335.

[0095] Please see Figure 9 and Figure 10 The rotating shaft D335 includes:

[0096] Two rotating shafts 3351 are respectively mounted on two angle adjustment structures 32 (the specific rotating shaft 3351 is connected to the rotating shaft C3228 for power transmission).

[0097] A connecting shaft 3352 is connected between the two rotating shafts 3351; the connecting shaft 3352 and the two rotating shafts 3351 are arranged in a straight line.

[0098] Two mounting slots 3354 are respectively opened on two rotating shafts 3351;

[0099] Two hydraulic telescopic rods B3353 are respectively installed inside the two mounting slots 3354; one end of the hydraulic telescopic rod B3353 is fixed to the end of the mounting slot 3354, and the other end is fixed to the drive column 334; the hydraulic telescopic rod B3353 is used to control the sliding position of the drive column 334 on the rotating shaft 3351 by telescoping.

[0100] Please see Figure 9 and Figure 10 The telescopic cylinder 333 includes a telescopic cylinder body 336, which includes multiple support plates 337. The multiple support plates 337 are arranged in a ring array around the rotating shaft D335. A rotating connector 338 is fixed at the center of the support plate 337. The support plate 337 is rotatably mounted on the connecting shaft 3352 through the rotating connector 338. The end of the support plate 337 abuts against the drive column 334.

[0101] Please see Figure 10 The drive column 334 is frustum-shaped; the rotating connector 338 includes a U-shaped connecting plate and a positioning plate, with the positioning plate rotatably mounted on the U-shaped connecting plate.

[0102] Therefore, multiple roller structures 33 rotate relative to each other, and multiple sets of unit roller components 31 are arranged with different arcs to complete the self-bending adjustment of the movable roller line 3. Then, the hydraulic telescopic rod B3353 at one end of the rotating shaft D335 is activated. The hydraulic telescopic rod B3353 pulls the drive column 334 at this end against the support plate 337. Since the drive column 334 is frustum-shaped, it can make the support plate 337 rotate around the rotating connector 338. During this process, the hydraulic telescopic rod B3353 at the other end of the rotating shaft D335 will cooperate to push out the drive column 334 at the other end of the rotating shaft D335 to cooperate with the rotation of the support plate 337. This realizes that the telescopic cylinder 333 can change to frustum-shaped of different sizes to cooperate with the different arc arrangements of multiple sets of unit roller components 31 and the different bending arcs of the movable roller line 3, reduce the gap between adjacent rollers 331, and improve the adaptability of the movable roller line 3.

[0103] In summary: The angle adjustment structure 32 drives the adjacent roller structures 33 to rotate relative to each other via the hydraulic telescopic rod A3215, causing multiple sets of unit roller components 31 to continuously and infinitely rotate in arc. This, combined with the hydraulic telescopic rod B3353 pulling the frustum-shaped drive column 334 against the support plate 337, allows the telescopic cylinder 333 to change into different sizes of frustum shapes and cooperate with each other. While the bending arc of the turning machine is infinitely adjusted, the telescopic cylinder 333 can automatically change its own taper size as the arc changes, compensating in real time for the end gap caused by the change in the included angle of the axes of the adjacent roller structures 33. This ensures that the conveying surface remains in a close fit throughout the entire bending adjustment range, completely eliminating the hidden danger of jamming caused by the increased gap after bending in traditional adjustable turning machines, and realizing continuous conveying with variable curvature and zero gap.

[0104] The hydraulic telescopic rod C changes the length of the telescopic shaft 3223 by adjusting the insertion depth, so as to cooperate with the relative rotation of the two roller structures 33 and carry out stable power transmission. It works in conjunction with the hydraulic telescopic rods B3353 at both ends of the shaft D335 to push the frustum-shaped drive column 334, so that the support plate 337 flips and changes the frustum-shaped size of the telescopic cylinder 333. After working together, after the turning machine adjusts the bending shape, not only does the length of the power transmission component 322 automatically adapt to the new geometric relationship, but the taper of the telescopic cylinder 333 also changes continuously with the change of the bending radius. It accurately matches the difference in the conveyor line speed between the inner and outer sides of the turn, so that the material can achieve smooth pure rolling turning without the need for an additional differential device. This solves the problem of material rubbing and deflection caused by speed difference when turning with variable curvature.

[0105] Multiple sets of fixed roller conveyors 1 and multiple sets of movable roller conveyors 3 work together. Through multiple angle adjustment structures 32, the movable roller conveyors 3 can complete the overall structure of different shapes and arrangements. They are combined with the telescopic cylinder 333 through the cooperation of the drive column 334 and the support plate 337 to change the taper and reduce the gap through a gap adaptive mechanism. The whole turning machine is no longer limited to a preset single arc path. It can be freely arranged into S-shape, variable curvature arc, or even asymmetrical irregular shape according to the obstacle conditions on site. Moreover, the conveying gap and the speed difference between the inner and outer sides of each bending node are adaptively compensated. This allows complex spatial turning tasks that originally required multiple fixed-angle turning machines to work in relay to be completed by this one machine. It greatly breaks through the dependence of traditional turning machines on regular turning radii and significantly expands the precise adaptability to narrow, irregular and irregular sites.
