Description

Technical Field

[0001] This application relates to the field of strip coil turning machines, and more particularly to a strip coil turning machine for use in automated production lines. Background Technology

[0002] Steel strip coils are narrow and long steel plates produced by various steel rolling enterprises to meet the needs of industrialized production of various metal or mechanical products in different industrial sectors. Due to their advantages of high strength, wear resistance, and corrosion resistance, they are widely used in the manufacture of automotive parts, mechanical parts, electronic equipment, building materials, etc. after being processed and customized according to requirements.

[0003] The production process of strip steel coils is briefly described as follows: the steel plate is first pretreated to remove oxides, grease and other substances from the surface, and then sent to a rolling mill for multiple pressing and stretching to reduce the thickness, enhance the surface quality and obtain the required size. The cold-rolled steel plate is cut into the required length or width, and after surface treatment again, it is coiled into a steel coil by a coiler. Finally, it is transported and unloaded by a conveyor line.

[0004] Reference Figure 1 Steel strip coils, being in the form of steel coils, facilitate transportation and storage while protecting the surface quality of the steel strip coils.

[0005] To improve production efficiency and reduce the workload of technicians, automated production lines for strip steel coil manufacturing have been developed. These lines combine a series of devices and are centrally controlled to automate the entire strip steel coil production process. Considering the subsequent packing and transportation of the strip steel coils, a strip steel coil turning machine is typically installed at the end of the automated production line to flip the strip steel coils from a vertical to a horizontal position.

[0006] Currently, the most common type of strip coil turning machine in the industry is the cylindrical rolling turning machine, but it is large in size, requires a large space, and has a high turning working surface, making it unsuitable for automated production lines.

[0007] In response to the aforementioned technologies, in order to connect the automated conveyor line and assembly line of strip steel coils, a small-sized strip steel coil turning machine that reduces space occupation should be designed to achieve fully automated operation of the strip steel coil production line. Summary of the Invention

[0008] In order to connect the automated conveyor line and assembly line of strip steel coils and realize the fully automated operation of the strip steel coil production line, this invention provides a strip steel coil turning machine for use in automated production lines.

[0009] The present invention provides a strip coil turning machine for use in automated production lines, which adopts the following technical solution:

[0010] A strip coil turning machine for use in automated production lines includes a frame, on which a turning mechanism and a conveying mechanism are installed. The turning mechanism and the conveying mechanism operate in sequence to turn the strip coil to a horizontal position and then transport it out.

[0011] The flipping mechanism includes:

[0012] The first flip plate is set on the top side of the frame, with one side end rotatably connected to both sides of the frame. It is equipped with positioning components to support and position the strip steel coil in a vertical state.

[0013] The second flip plate is set on the top side of the frame, with one side fixed to the rotating side of the first flip plate and always perpendicular to the first flip plate, and is used to support the strip steel coil in a horizontal state.

[0014] A power unit is located on one side of the second flip plate to drive the first and second flip plates to rotate.

[0015] By adopting the above technical solution, the frame serves as the main support structure of the strip coil turning machine, used to install the conveying mechanism. The strip coil is conveyed to the turning mechanism on the frame, changing its vertical position to a horizontal position before being transported out of the strip coil turning machine to the outer packing line by the conveying mechanism. This reduces the workload of workers. The strip coil turning machine adapted for automated production lines improves the size and operation of traditional cylindrical rolling turning machines, connecting internal and external production and packing to achieve full-line automation. Furthermore, the method of rotating the first and second turning plates around the hinged side in the above solution improves upon the traditional rolling turning mechanism, reducing the space occupied during operation and increasing... To illustrate the flipping efficiency of a single strip coil, the flipping method described above is as follows: Initially, the first flipping plate is horizontal and the second flipping plate is vertical. The strip coil falls from the conveyor belt of the production line onto the first flipping plate, where it is positioned and fixed by the positioning component. The power component pulls the second flipping plate, causing the first flipping plate to gradually rotate to a horizontal position. Correspondingly, the strip coil rotates synchronously with the first flipping plate to a vertical position. The support plate supporting the strip coil gradually changes from the first flipping plate to the second flipping plate. Finally, the second flipping plate and the strip coil mounted on it are horizontal, while the first flipping plate is vertical. The strip coil is then transported out by the conveying mechanism.

[0016] Optionally, the positioning component includes;

[0017] The positioning frame, fixed to the first flip plate, includes two frame rods perpendicular to the first flip plate, forming a space between the frame and the second flip plate to accommodate the steel coil;

[0018] The positioning plate is located between the first flip plate and the positioning frame and the second flip plate. Its two sides are inclined upwards to restrict the rolling of the strip steel coil after installation.

[0019] The limiting plate is perpendicular to the first flip plate and is slidably connected to the positioning frame. A driving component is provided on one side of the positioning frame to drive the limiting plate to press against the strip steel coil installed on the positioning plate.

[0020] By adopting the above technical solution, the positioning frame, positioning plate, and limiting plate work together to restrict the strip coil when it falls onto the first flipping plate and during the flipping process of the two flipping plates. Specifically, the strip coil falls from the conveyor line of the production line into the space between the positioning frame and the second flipping plate, landing vertically on the positioning plate. The two upward-sloping sides of the positioning plate restrict the tangential displacement of the strip coil, which is vertically placed in the center of the positioning plate. At the same time, the frame rod of the positioning frame restricts the axial movement space of the strip coil. After the strip coil is stabilized, the driving component drives the limiting plate to press against the strip coil, thus pressing the strip coil against the second flipping plate. In summary, the frame rod on the positioning frame restricts the axial space of the strip coil, the positioning plate restricts the tangential rolling of the strip coil, and the driving component drives the limiting plate to press against the strip coil, thereby achieving the positioning of the strip coil before flipping and the fixation during the flipping process.

[0021] Optionally, the positioning plate can be slidably connected to the first flip plate, and correspondingly, the first flip plate is provided with a guide rail for guiding the sliding of the positioning plate.

[0022] By adopting the above technical solution, technicians can adjust the position of the positioning plate to match the width of the strip steel plate cut on the production line, ensuring that the two ends of the strip steel coil extend equidistantly from the positioning plate in the axial direction, thus ensuring the fixing effect of the positioning plate. In the above solution, the fixing method after sliding can be bolt fixing. Accordingly, the guide rail in the above solution should be provided with a groove for accommodating the bolt.

[0023] Optionally, the positioning plate includes;

[0024] Side plates are provided at both ends of the positioning plate. The two side plates are inclined towards each other, and the downward inclined end is hinged to the positioning plate. A spring is provided between the side plate and the positioning plate. When the side plate rotates around the hinge side toward the positioning plate, the spring is compressed.

[0025] By adopting the above technical solution, the strip coil is buffered on the first flipping plate when it falls. The strip coil falls to the contact positioning plate and first contacts the inclined upward side plates on both sides of the positioning plate. Under the action of gravity, the strip coil continues to fall, pressing the side plates to rotate downward around the hinge point. The side plates compress the springs, and the springs transmit the upward buffering resistance of the strip coil through the side plates, avoiding the strip coil from falling at its original speed and hitting the positioning plate, which would damage the first flipping plate and cause deformation over a long period of time.

[0026] Optional, also includes;

[0027] The bracket, together with the strip coil, is placed on the flipping mechanism. After flipping synchronously with the strip coil to a horizontal state, it supports the bottom of the strip coil. Correspondingly, the second flipping plate is provided with a fixing component for fixing the bracket.

[0028] By adopting the above technical solution, the bracket is used to isolate the strip coil from the second flipping plate. When the strip coil is flipped to a horizontal state with the two flipping plates, the strip coil is supported by the second flipping plate. Direct contact between the cut surface of the strip plate and the second flipping plate will increase the risk of scratches and damage to the surface of the second flipping plate, and may also damage the protective coating on the surface of the strip. In order to protect the surface of the second flipping plate and the strip coil, a bracket is added between the two. The bracket corresponds one-to-one with the strip coil. In addition to the protective function, the bracket can also provide stable support during the transport of the strip coil, which is especially important for strips that are large or heavy, ensuring that the strip remains balanced and stable during the flipping process and does not tilt or slide. Based on this, the bracket should be installed on the first flipping plate at the same time as each strip coil falls. In practical applications, side plates perpendicular to the second flipping plate can be set on both sides of the second flipping plate to limit the falling direction of the bracket and make the bracket fall accurately to the fixed component.

[0029] Optionally, the fixing component includes;

[0030] A fixing block is disposed on the first flip plate, and the gap between it and the second flip plate is used to engage the bracket; correspondingly, a driving component for driving the fixing block to move is provided on the side of the first flip plate opposite to the fixing block.

[0031] By adopting the above technical solution, an additional fixing block is added in the middle part between the positioning frame and the second flip plate. The space between the fixing block and the second flip plate is used to clamp the bracket, and the fixing block is set to fix the bracket to the second flip plate during the flipping process, thereby realizing the positioning of the bracket. Based on this, the space between the fixing block and the second flip plate should be slightly larger than the height of the bracket, so as to limit the movement space of the bracket without affecting the placement of the bracket. The above solution is set to drive the fixing block to slide in a direction perpendicular to the first flip plate. When the bracket is installed on the first flip plate from top to bottom, the driving component drives the fixing block to move upward to the top of the first flip plate, shortening the time of free swaying of the bracket, thereby improving the installation stability of the first flip plate.

[0032] Optionally, the conveying mechanism includes;

[0033] The sprocket is located at the four corners of the second flip plate near the first flip plate. Two chains perpendicular to the first flip plate are meshed on it. When the bracket and the strip coil are flipped to a horizontal state, the sprocket drives the chain to drive the bracket to slide.

[0034] The transition roller is horizontally positioned on the side of the second flip plate away from the first flip plate.

[0035] By adopting the above technical solution, after the second flip plate flips to a horizontal state, the bottom sides of the bracket are mounted on two sprockets. The sprockets and chains serve as the main conveying components. The rotation of the sprockets drives the chain transmission, transporting the bracket to the subsequent packing line for shipment. The above solution uses chain transmission to replace the traditional cylindrical rolling method. The frame is set horizontally on one side corresponding to the second flip plate and its height is aligned with the packing line behind it, adapting to the production line setup. When the frame is stationary, it can directly transport the bracket and strip steel coil to the rear, ensuring that the chain-driven bracket transmission can effectively connect with the packing line. In actual application, the height of the frame should be repeatedly adjusted and confirmed, aligning the height of the transition rollers on the frame with the height of the conveyor belt surface behind it to avoid collisions during conveying.

[0036] Optionally, the power component includes;

[0037] The hydraulic cylinder has its body hinged to the bottom of both sides of the frame, and its piston rod end is rotatably connected to both sides of the second tilting plate. The rotation of the second tilting plate is achieved by the contraction of the piston rod.

[0038] By adopting the above technical solution, the hydraulic cylinder pulls the second tilting plate to tilt, and its transmission has the advantages of smooth and continuous operation, especially in the process of starting, accelerating, decelerating and stopping. The use of hydraulic cylinder transmission can provide stability in the rotation process of the two tilting plates. In addition, the hydraulic system has extremely strong load-bearing capacity and can be suitable for the tilting of large-volume steel coils. In the above solution, the hydraulic cylinder is used instead of the cylindrical chain rolling method. The high efficiency and stability of the hydraulic cylinder are more suitable for the operation mode of automated production line.

[0039] In summary, this application has the following beneficial effects:

[0040] This application uses a frame as the main structure of the strip coil turning equipment, which is adapted to the height settings of the conveyor belts on both sides in the automated production line. A first turning plate and a second turning plate are set in a fixed working area to replace the cylindrical turning body of the traditional turning machine. The operation mode of the first turning plate and the second turning plate can turn in place to replace the operation mode of the traditional cylindrical rolling turning. The stability of turning is improved by using hydraulic cylinder drive, so that the strip coil fixed on the first turning plate changes from a vertical state to a horizontal state as the two turning plates rotate. The turning efficiency of the two turning plates in this application is greatly enhanced compared with the turning efficiency of the traditional rolling turning, which is more suitable for the output requirements of the automated production line.

[0041] The strip coil turning machine in this application occupies less space than the traditional cylindrical rolling turning machine, and has a lower frame height, making it a simpler and more efficient production and packing line for strip coil turning machines. Attached Figure Description

[0049] The following is in conjunction with the appendix Figure 2-6 This application will be described in further detail.

[0050] This application discloses a strip coil turning machine applied to an automated production line. (Refer to...) Figure 2 A strip coil turning machine for use in automated production lines includes a frame 2 as the main support structure of the strip coil turning machine. Guardrails 21 are erected on both sides of the frame 2 to serve as the boundary of the work area for protection. A control panel 22 is also provided on one side of the frame 2 for installing a control panel to facilitate technicians to adjust the operating parameters of the strip coil turning machine.

[0051] Reference Figure 2 and Figure 3The frame 2 is equipped with a first flipping plate 3 and a second flipping plate 4 that are perpendicular to each other. One side of the first flipping plate 3 is fixedly connected to one side of the second flipping plate 4, and the side of the two fixedly connected sides is rotatably connected to the two sides of the top wall of the frame 2. The first flipping plate 3 and the second flipping plate 4 always remain perpendicular. The first flipping plate 3 and the second flipping plate 4 serve as the basic structure for flipping the installation state of the strip steel coil 1. The initial state is that the first flipping plate 3 is horizontal and the second flipping plate 4 is vertical. The strip steel coil 1 falls from the production line onto the first flipping plate 3, and the first flipping plate 3 and the second flipping plate 4 drive the strip steel coil 1 to rotate synchronously by 90 degrees. After flipping, the first flipping plate 3 is in a vertical state and the second flipping plate 4 is in a horizontal state, and the strip steel coil 1 changes from vertical to horizontal.

[0052] Reference Figure 3 Based on the above concept, in this embodiment, a hydraulic cylinder 23 is respectively installed on both sides of the frame 2. The cylinder body of the hydraulic cylinder 23 is hinged to the bottom side of the frame 2, and the piston rod of the hydraulic cylinder 23 is hinged to the second flip plate 4. To avoid structural interference, a lug plate 41 is extended on both sides of the second flip plate 4 corresponding to the piston rod of the hydraulic cylinder 23, and a lug groove 42 is opened accordingly, so that the end of the piston rod of the hydraulic cylinder 23 passes through the lug groove 42 and is rotatably connected to the lug plate 41. The two hydraulic cylinders 23 operate synchronously. In the initial state, the piston rod of the hydraulic cylinder 23 is kept in the extended state. In the flipping state, the piston rod of the hydraulic cylinder 23 is smoothly retracted, driving the first flip plate 3 and the second flip plate 4 together with the strip coil 1 to rotate stably by 90°. After the strip coil 1 is in a horizontal state, the piston rod of the hydraulic cylinder 23 remains in the retracted state.

[0053] Unlike the traditional cylindrical rolling type of flipping, this embodiment uses dual hydraulic cylinders 23 to drive the strip coil 1 to flip. Utilizing the advantages of high stability, high reliability, and high speed of the hydraulic cylinders 23, the stability of the strip coil 1 during the flipping process is maintained while also improving the flipping efficiency. In addition, this embodiment uses hydraulic cylinders 23 to drive the first flipping plate 3 and the second flipping plate 4 to flip 90° within a fixed area, which is suitable for the design concept of a small-sized and automated strip coil 1 production line, ensuring effective connection between the strip coil 1 production line and the transport line.

[0054] Looking back Figure 2 The first flip plate 3 receives the vertical transport end of the production line, positions and fixes the strip steel coil 1 that falls vertically from the front end of the production line. Thus, the first flip plate 3 is provided with a positioning component 31 to limit the offset of the tangential direction and the axial direction of the strip steel coil 1 after it falls. The positioning component 31 includes a positioning frame 311 fixed to the first flip plate 3. The positioning frame 311 includes two positioning rods 312 as the main structure of the positioning frame 311. The two positioning rods 312 are set perpendicular to the first flip plate 3. The plane formed by the two positioning rods 312 is parallel to the second flip plate 4. The space between the two positioning rods 312 and the second flip plate 4 is used to accommodate the strip steel coil 1.

[0055] In this embodiment, when the strip coil 1 is transported out from the production line exit at the front end of the strip turning machine, it falls between the second turning plate 4 and the positioning rod 312. The positioning rod 312 serves to limit the axial movement of the strip coil 1, preventing it from tilting axially when it collides with the first turning plate 3. Based on this, in order to improve the limiting effect, the positioning frame 311 is designed in a plate shape to limit one side of the strip coil 1, thereby increasing the contact area between the positioning rod 312 and the strip coil 1 when the strip coil 1 tilts.

[0056] Reference Figure 2 The positioning component 31 also includes a limiting plate 313 that is slidably connected to the middle part of the positioning frame 311. The limiting plate 313 is set parallel to the second flip plate 4. The limiting plate 313 slides in a direction perpendicular to the surface of the second flip plate 4 to press and fix the strip coil 1 positioned on the first flip plate 3. In order to realize the active sliding of the limiting plate 313, in this embodiment, a first driving cylinder 314 is fixedly connected to the positioning frame 311 corresponding to the limiting plate 313. The cylinder body of the first driving cylinder 314 is parallel to the first flip plate 3 and perpendicular to the second flip plate 4. The piston rod of the first driving cylinder 314 is fixedly connected to the side of the limiting plate 313 away from the second flip plate 4. When the strip coil 1 falls onto the first flipping plate 3 and is positioned, the first drive cylinder 314 extends its piston rod and pushes the limiting plate 313 toward the strip coil 1. The limiting plate 313 presses against the strip coil 1 in the direction of the second flipping plate 4 to complete the fixation. The piston rod of the first drive cylinder 314 remains extended until the first flipping plate 3 and the second flipping plate 4 complete the flipping.

[0057] Reference Figure 2 and Figure 4 The positioning assembly 31 also includes a positioning plate 32 disposed on the first flip plate 3. The positioning plate 32 is disposed between the positioning rod 312 and the second flip plate 4 on the first flip plate 3, and is used to directly support the strip steel coil 1. The length of the positioning plate 32 is greater than its width, and its length direction is parallel to the second flip plate 4. The positioning plate 32 is composed of two side plates 321 and a bottom plate 322. The two side plates 321 are disposed on both sides of the bottom plate 322, and the two side plates 321 are close to each other on the side. Connected to the base plate 322, the two side plates 321 are inclined to the side away from the base plate 322. Thus, the two side plates 321 and the base plate 322 form a positioning plate 32 with a relatively concave middle part. When the strip coil 1 falls onto the positioning plate 32, the two side plates 321 on both sides of the positioning plate 32 limit the strip coil 1 on the positioning plate 32, preventing the strip coil 1 from rolling along the tangential direction. Together with the limiting plate 313 and the positioning rod 312, the strip coil 1 is fixed in all directions.

[0058] Reference Figure 4Considering that the collision between the falling steel coil 1 and the base plate 322 may damage the positioning plate 32 and the steel coil 1, and that prolonged operation may damage the first flipping plate 3, this embodiment makes structural improvements to the base plate 322 and side plate 321 of the positioning plate 32. Springs 323 are respectively provided on the base plate 322 corresponding to the two side plates 321. The springs 323 are perpendicular to the base plate 322, with one end fixed to the base plate 322 and the other end abutting against the side of the side plate 321 near the base plate 322. The two side plates 321 are hinged to the base plate 322 on their opposite sides, allowing the two side plates 321 to face downwards around the hinged side. Plate 322 rotates, abutting against and compressing spring 323; thus, the strip coil 1 falls and abuts against the two side plates 321, and the two side plates 321 compress spring 323. The elastic force of spring 323 buffers the weight of strip coil 1, thereby reducing the impact between strip coil 1 and bottom plate 322. In addition, since the weight of strip coil 1 is large when it falls, in order to avoid excessive compression of spring 323, which would damage spring 323, and to avoid excessive rotation angle of side plate 321, which would reduce the restraining force on strip coil 1, inclined blocks with the same inclination angle as side plate 321 are set on both sides of the two side plates 321 to abut against the side plate 321 after it rotates around the hinge side, so as to protect spring 323.

[0059] Reference Figure 2 and Figure 5 Considering the different cutting thicknesses of different steel coils 1, in order to ensure that the extension length of the steel coil 1 on both sides of the positioning plate 32 is the same, the position of the positioning plate 32 is different on different production lines. In order to achieve the adjustment of the overall position of the positioning plate 32, multiple parallel guide rails 315 are fixed on the plate surface of the first flip plate 3. The length direction of each guide rail 315 is perpendicular to the plate surface of the second flip plate 4. Each guide rail 315 is slidably connected to a guide block 316. The guide block 316 is provided with bolt holes for connecting the base plate 322 of the positioning plate 32. After the base plate 322 is fixed on multiple guide blocks 316, the overall sliding of the positioning plate 32 is achieved by the sliding of the guide block 316 on the guide rail 315.

[0060] In summary, the positioning component 31 and its positioning principle are explained as follows: When the strip coil 1 falls onto the surface of the first flip plate 3, between the positioning frame 311 and the second flip plate 4, the strip coil 1 first abuts against the two side plates 321 of the positioning plate 32 during its descent. The two side plates 321 of the positioning plate 32 rotate towards the bottom plate 322 and compress the spring 323. The elastic force of the spring 323 offsets part of the gravity of the strip coil 1 as it falls, reducing the impact force of the strip coil 1 on the bottom plate 322 until the strip coil 1 stably contacts the bottom plate 322 of the positioning plate 32. Then, the first drive cylinder 314 operates, extending the piston rod to push the limiting plate 313 against the strip coil 1, thus fixing the strip coil 1 against the second flip plate 4.

[0061] Reference Figure 6 The cut surface of the steel coil 1 should avoid contact with the flipping plate to prevent scratching or damaging the flipping plate. Especially when the steel coil 1 is flipped to a horizontal state, the second flipping plate 4 connects to the first flipping plate 3 as the main support structure of the steel coil 1. During the connection process, the cut surface of the steel coil 1 is prone to scratching the second flipping plate 4. Therefore, in this embodiment, a bracket 24 corresponding to the steel coil 1 should be set between the second flipping plate 4 and the steel coil 1. When the steel coil 1 is flipped to a horizontal state, it will block the steel coil 1 from the second flipping plate 4 and fill the space between the steel coil 1 and the second flipping plate 4, reduce the fixing time of the steel coil 1, and improve the fixing efficiency of the steel coil 1 to a certain extent.

[0062] Reference Figure 5 and Figure 6 The bracket 24 should correspond one-to-one with the strip coil 1. When the strip coil 1 falls from the production line, the bracket 24 should fall together with the strip coil 1 to the part between the strip coil 1 and the second flip plate 4. Based on this, the bracket 24 should be fixed. Multiple fixing blocks 317 are set on the first flip plate 3 corresponding to the part between the positioning rod 312 and the second flip plate 4. The part between the fixing block 317 and the second flip plate 4 is used to clamp the bracket 24, and the part between the fixing block 317 and the positioning frame 311 is used to clamp the strip coil 1. Thus, the bracket 24 and the strip coil 1 are positioned respectively during the flipping process.

[0063] Reference Figure 2 and Figure 5 Considering that the falling of the fixed block 317 and the falling of the steel coil 1 are both free fall processes, and that the distance between the fixed block 317 and the second flip plate 4 is set according to the width of the bracket 24, in order to ensure that the fixed block 317 falls accurately between the bracket 24 and the second flip plate 4, a second driving cylinder 318 perpendicular to the surface of the first flip plate 3 is fixedly connected to the side of the first flip plate 3 opposite to the fixed block 317. The piston rod of the second driving cylinder 318 passes through the first flip plate 3 and connects to the fixed block 317, making the second driving cylinder 318 the active component for pushing the fixed block 317 upward. Thus, before the bracket 24 and the steel coil 1 fall synchronously, the second driving cylinder 318 extends its piston rod, pushing the fixed block 317 away from the surface of the first flip plate 3, increasing the restricted time of the bracket 24's falling process. After the bracket 24 completes its falling, the second driving cylinder 318 retracts its piston rod, causing the fixed block 317 to reset.

[0064] Looking back Figure 2In this embodiment, cylinder slots 25 are provided on both sides of the second flip plate 4, and a corner cylinder 251 is installed in the cylinder slots 25. The corner cylinder 251 is perpendicular to the second flip plate 4 and parallel to the first flip plate 3. A pressure block is provided at the end of the rotating rod of the corner cylinder 251. The operation of the corner cylinder 251 drives the pressure block to rotate and press against the bracket 24 installed on the second flip plate 4, thereby fixing the bracket 24 during the flipping process. In the initial state, the pressure block is parallel to both sides of the second flip plate 4. When the bracket 24 falls between the fixing block 317 and the second flip plate 4, the rotating rod of the corner cylinder 251 rotates, driving the pressure block to rotate 90° in the plane parallel to the second flip plate 4. At the same time as the rotation, the corner cylinder 251 retracts the rotating rod. After the pressure block has rotated, it presses the bracket 24 against the surface of the second flip plate 4, thereby fixing the bracket 24.

[0065] Reference Figure 2 and Figure 6 After the steel coil 1 and the bracket 24 are flipped to a horizontal position, a conveying mechanism needs to be installed on the second flipping plate 4 to facilitate the transport of the bracket 24 and the steel coil 1. In this embodiment, the conveying mechanism includes a chain installed on the side of the second flipping plate 4. One chain is installed on each of the two sides of the second flipping plate 4 perpendicular to the first flipping plate 3, and sprockets 43 for driving the chain transmission are installed in the dead corners of the second flipping plate 4. Correspondingly, the width of the two sides of the bracket 24 is the same as the width of the second flipping plate 4. After the corner cylinder 251 releases the fixation of the bracket 24, the sprockets 43 rotate, transporting the horizontally positioned steel coil 1 carried on the bracket 24 out.

[0066] It should be noted that, in order to highlight the sprocket 43, the chain is not shown in the figure, and the chain is existing technology and is not a technical point of this embodiment, so it will not be described in detail.

[0067] Reference Figure 2 and Figure 6 A transition roller 26 is provided on the side of the second flip plate 4 away from the first flip plate 3. The transition roller 26 is horizontally rotatably connected to the frame 2 and serves as a receiving mechanism for the mounting bracket 24. The bracket 24 transported from the second flip plate 4 is transferred to the packing line behind the frame 2 via the transition roller 26.

[0068] The implementation principle of a strip coil turning machine applied to an automated production line according to an embodiment of this application is as follows: The frame 2 is installed at the junction of the strip coil 1 production line and the packing line. In the initial state, the first turning plate 3 is in a horizontal state and the second turning plate 4 is in a vertical state. Correspondingly, the hydraulic cylinder 23 used to drive the first turning plate 3 and the second turning plate 4 keeps the piston rod extended.

[0069] The second drive cylinder 318 drives the fixing block 317 away from the first flip plate 3, dividing the space between the positioning frame 311 and the second flip plate 4 into two parts. The strip coil 1 falls from the front production line to the part between the positioning frame 311 and the fixing block 317 of the first flip plate 3, while the bracket 24 falls from a dedicated conveyor line to the part between the fixing block 317 and the second flip plate 4 of the first flip plate 3.

[0070] The bracket 24 and the steel coil 1 simultaneously and stably land on the first tilting plate 3. The second drive cylinder 318 retracts its piston rod, causing the fixing block 317 to return to its original position on the first tilting plate 3, thus avoiding interference with the fixing of the steel coil 1. At the same time, the corner cylinders 251 on both sides of the second tilting plate 4 operate, rotating and retracting their rotating rods, causing the pressure block to press against the bracket 24, fixing the bracket 24 to the second tilting plate 4. The side of the bracket 24 closest to the second tilting plate 4 abuts against two chains.

[0071] During the descent of the steel coil 1, it first abuts against the two side plates 321 of the positioning plate 32. The two side plates 321 of the positioning plate 32 rotate towards the bottom plate 322 and compress the spring 323. The elastic force of the spring 323 offsets part of the gravity of the steel coil 1 as it falls, reducing the impact force of the steel coil 1 on the bottom plate 322. The steel coil 1 then stably contacts the bottom plate 322 of the positioning plate 32. Then, the first drive cylinder 314 operates, extending the piston rod to push the limiting plate 313 against the steel coil 1, and abuts the steel coil 1 against the second flip plate 4. The two side plates 321 restrict the rolling tendency of the steel coil 1 in the tangential direction, and the limiting plate 313 abuts the steel coil 1 against the bracket 24.

[0072] After the steel coil 1 is fixed to the bracket 24, the hydraulic cylinder 23 retracts the piston rod, pulling the second flip plate 4 and the first flip plate 3 to rotate 90° around the hinge side, until the second flip plate 4 turns to a horizontal state and the first flip plate 3 turns to a vertical state.

[0073] The rotating rod of the corner cylinder 251 drives the pressure block to reset, releasing the fixation of the bracket 24. Then the sprocket 43 rotates to drive the chain drive, which, together with the rotating roller, moves the bracket 24 out.

[0074] After being transported out, the hydraulic cylinder 23 is reset, causing the first flipping plate 3 and the second flipping plate 4 to return to their initial state. The above process is repeated to realize the automated flipping of the strip coil 1 production line.

[0075] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
