Description

Technical Field

[0001] This invention relates to the field of copper rod processing technology, specifically to a plum blossom take-up device for a copper rod continuous casting and rolling mill. Background Technology

[0002] In the continuous casting and rolling production line of copper rods, take-up is a key step to ensure that the final product has a regular shape and is easy to store and transport. Existing take-up devices generally use a basic concentric circle (similar to the shape of a mosquito coil) method to horizontally wind up the continuously extruded wire to receive and package the copper material produced by the production line.

[0003] However, this traditional concentric circle winding method has obvious structural drawbacks in actual operation. During the continuous winding process, the copper wire is always affected by its own tension. Under the single parallel superposition trajectory of concentric circles, it is difficult for the wire layers to interlock with each other, inevitably forming a large number of tiny gaps. As the height of the coil increases, these gaps accumulate and enlarge, resulting in an extremely loose overall coil structure after the final formation, lacking internal interlocking constraints.

[0004] This loose physical state directly leads to serious hidden dangers in subsequent processing. When the winding is completed and workers need to handle the material, or during the subsequent winding transfer and hoisting process, the loose winding will frequently break apart and large areas of copper wire will slip or fall off if it is shaken by external force. This not only greatly increases the labor intensity of manually reorganizing the loose winding, but also seriously delays the overall production flow. Therefore, it is urgent to make technical improvements to the existing winding method and equipment structure. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a plum blossom take-up device for copper rod continuous casting and rolling mills. By utilizing the dynamic guidance of the wire throwing mechanism and the stop bar to form an interlaced plum blossom-shaped trajectory, the device aims to eliminate gaps between wire coil layers and prevent loose wire from falling off.

[0020] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0021] 1. This invention uses a wire-spinning mechanism to drive the copper wire to rotate synchronously. In conjunction with the sliding adjustment rod inside the frame and the multi-angle rotating stop rod, it applies constantly changing positional pushing and guiding constraints to the rotating copper wire. This dynamic multi-dimensional guidance causes the copper wire to form an interlaced, layered plum blossom-shaped superimposed trajectory on the placement plate. The cross-weaving of the wire itself effectively squeezes the gaps between layers, achieving a high-density, heat-dissipating, and extremely stable winding effect, fundamentally eliminating the phenomenon of tangled wires and falling off during material handling and transportation.

[0022] 2. This invention uses a hydraulic cylinder to drive the first and second rotating rods to rotate, causing the third rotating rod and its end baffle to unfold inwards towards the frame. This ingeniously achieves physical isolation between the material receiving and unloading stations without stopping the machine. The copper wire falling above the baffle can seamlessly continue its cloverwise winding process, while the operator can simultaneously and safely remove the completed high-density wire roll below the baffle. This completely breaks the limitation of traditional equipment requiring machine shutdown and manual material replacement, greatly improving the continuous operation efficiency of the production line.

[0023] 3. This invention utilizes the precise track of the sliding rod, limiting rod, and the internal limiting groove of the second rotating rod to drive the third rotating rod to move the baffle downward, applying uniform downward pressure to the formed plum blossom wire coil for secondary compaction. At the same time, it cleverly utilizes the pneumatic principle of the piston and the inlet and outlet one-way valve inside the third rotating rod to automatically deliver pure gas to the exhaust frame and blow away the lower surface of the baffle during the lifting and lowering action, cleaning the adsorbed copper powder in real time, avoiding frictional wear on the copper rod surface caused by the pressing action, and comprehensively ensuring the appearance quality of the wire.

Detailed Implementation

[0038] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical solution of the present invention, rather than limitations thereof.

[0039] Example 1

[0040] like Figures 1 to 12As shown in the embodiment of the present invention, a copper rod take-up device for a continuous casting and rolling mill includes a frame 1 and a receiving assembly 4. An outer cylinder take-up assembly 2 is provided inside the frame 1. The outer cylinder take-up assembly 2 includes a lower frame 21 fixedly connected to the upper surface of the frame 1. An upper frame 22 is provided above the lower frame 21. A moving rod 221 is slidably connected to the upper surface of the upper frame 22. A stop rod 222 is rotatably connected to one end of the moving rod 221. A wire throwing mechanism 3 is provided on the inner upper surface of the frame 1. A second connecting plate 213 is fixedly connected to the side surface of the lower frame 21. A third rotating rod 26 is rotatably and slidably connected inside the second connecting plate 213. A baffle 27 is fixedly connected to one end of the third rotating rod 26.

[0041] like Figure 1 As shown, the receiving assembly 4 includes a lifting plate 41, which is a prior art technology. The lifting plate 41 is driven by hydraulic force to move through the scissor arm, thereby controlling the up and down movement of the placement plate 42. The placement plate 42 is slidably connected to the upper surface of the lifting plate 41.

[0042] like Figure 4 As shown, the lower frame 21 is rotatably connected to several first rotating rods 24, and each of the several first rotating rods 24 is fixedly connected to a fixing plate 241. The frame 1 is fixedly connected to a hydraulic cylinder 23. The several fixing plates 241 are rotatably connected to each other, and the interior of one of the fixing plates 241 is rotatably connected to the telescopic end of the hydraulic cylinder 23.

[0043] Specifically, in the existing plum blossom take-up device, the take-up operation and material unloading operation are generally completed at the same station. After a set of copper wires is taken up, the machine needs to be stopped and the taken-up copper wires need to be removed. After the machine is stopped, it is necessary to wait for the operator to unload the material and rearrange the copper wire take-up starting point. This process increases the work efficiency and working time, resulting in a decrease in the take-up efficiency of the take-up device, which in turn causes a decrease in the production efficiency of the continuous casting and rolling mill.

[0044] In order to avoid the technical problems of the existing plum blossom winding device, this device is used as follows: Before using the device, by adjusting the distance of the moving rod 221, the moving rod 221 drives the stop rod 222 to slide inside the upper frame 22, thereby forming a winding space suitable for the copper rod plum blossom coil forming.

[0045] like Figure 2 , Figure 3 , Figure 4As shown, when the winding operation is required, the external drive device drives the transmission wheel 33 to rotate, which in turn drives the transmission shaft 34 connected to the transmission wheel 33 to rotate, which in turn drives the spinning drum 36 to rotate. The rotation of the spinning drum 36 drives the spinning tube 35 to rotate, and the copper wire that passes through the top of the wire hole 32 and exits from the bottom of the spinning tube 35 rotates synchronously.

[0046] The tube 35 is a three-dimensional hollow tube with a preset diameter and wall thickness. The tube 35 is bent along its geometric center line, which is a spatial helical curve constrained on a rotating hyperboloid. To ensure that the curvature trajectory of the tube 35 accurately guides machining and achieves lossless and efficient guidance of the copper wire, in a right-handed three-dimensional Cartesian coordinate system O-XYZ, the central rotation axis of the transmission shaft 34 is set as the Z-axis, with the vertically downward direction being the negative direction of the Z-axis. The specific parametric equations of the spatial helical curve at the center of the tube 35 are constructed as follows:

[0047]

[0048] Where t is the axial travel independent variable of the geometric center line of the pipe 35, and its physical boundary value range is: Where L is the total axial length of the ejector pipe 35, in mm; The initial radius of the slinger (35) at the top inlet (i.e., the narrowest section of the throat of the single-leaf hyperboloid) is in mm, used to precisely match the radial output position of the end of the wire hole 32 inside the drive shaft 34; is the axial opening coefficient of the single-leaf hyperboloid, which is a dimensionless constant used to characterize the follow-up expansion slope of the sling 35 as it expands outward from top to bottom; The angular velocity coefficient of the spatial spiral curve, in rad / mm, is used to constrain the pitch and number of turns of the copper wire when it rotates inside the spinneret 35. The initial phase angle at the top entrance of the copper wire entering the spindle 35 is expressed in rad.

[0049] During operation, an external drive device rotates the transmission wheel 33 and the transmission shaft 34, thereby driving the spinning drum 36, which is fastened to the bottom of the transmission shaft 34, and the spinning tube 35, which is fixed to the outside of the spinning drum 36, to rotate synchronously around the Z-axis at high speed. The copper wire passes through the wire hole 32 and enters the interior of the spinning tube 35. Since the geometric center line of the spinning tube 35 strictly follows the above-mentioned single-leaf hyperboloid spiral parameter equation, the resultant force of the follow-up tangential force, gravity, and rotational centrifugal force on the copper wire in the tube cavity during high-speed rotation is highly coincident with the tangential direction of the axis of the spinning tube 35.

[0050] At this point, the normal compressive pressure of the copper wire on the inner wall of the tube 35 approaches zero, and the frictional resistance of the tube wall is greatly reduced. This completely avoids the phenomenon of copper wire seizing or tube blockage caused by centrifugal force at high speeds. In fact, at high speeds, the centrifugal force component can be used to enhance the follow-up falling power of the copper wire, significantly improving the smoothness of the wire's descent. At the same time, since the spatial curvature of the center line is continuous and without mechanical abrupt changes, the stress distribution of the copper wire during the follow-up falling process is extremely uniform, eliminating the phenomenon of local stress concentration. This effectively avoids bending and plastic deformation of the copper wire when passing through at high speeds, perfectly protecting the surface precision and overall mechanical properties of the wire. It ensures that there is no bouncing or oscillation throughout the falling process and that batch consistency is strong, making it perfectly adaptable to continuous industrial production.

[0051] Meanwhile, the stop lever 222 rotates along with the upper frame 22. As the copper wire rotates, it is pushed by the stop lever 222 at different positions. The angle of inclination of the stop lever 222 is different. Combined with the different lengths of extension of the stop lever 222 to the center of the upper frame 22 driven by the moving rod 221, the copper wire is pushed by rotation. Through the continuous change of the position and angle of the stop lever 222, the copper wire achieves a single-group alternating elliptical state. The repeatedly superimposed copper wire forms a plum blossom-shaped wire take-up state, which optimizes the existing concentric circle wire take-up method. The plum blossom wire take-up structure prevents the copper wire from scattering, ensures the stability of the overall wire take-up structure, and prevents the copper wire from being misaligned and crossing during the wire take-up process, thus preventing jamming.

[0052] As the steel coil is gradually wound up and its height changes, the lifting plate 41 can be driven to descend to adapt to the height change of the steel coil. At this time, the baffle 27 is located on the outside of the outer frame.

[0053] When the coil on the placement plate 42 is wound up to a certain height and the operator needs to retrieve it, the hydraulic cylinder 23 can be activated. The telescopic end of the hydraulic cylinder 23 drives the fixed plate 241 and the first rotating rod 24 to rotate. Through the cooperation of the connecting rod 231, the fixed plate 241 and the first rotating rod 24 rotate synchronously. The first rotating rod 24 drives the second rotating rod 25 inside it to rotate. The second rotating rod 25 drives the third rotating rod 26 to rotate synchronously. The third rotating rod 26 drives the baffle 27 at one end to rotate to the inside of the lower frame 21. After the baffle 27 rotates to its final position, the copper wire falls into the upper part of the baffle 27 for temporary storage. Then the operator can take out the coil that has been wound up below the baffle 27. After taking it out, the lifting plate 41 is driven to move the placement plate 42 to the lower part of the baffle 27. The baffle 27 is then driven to unfold to the outside of the lower frame 21. The coil wound up above the baffle 27 can then fall onto the placement plate 42 for winding.

[0054] This device drives the baffle 27 to rotate, which physically separates the winding station from the material picking station. The winding work can then be completed without stopping the machine. This device does not require stopping the machine to wait for material picking, avoiding production interruptions caused by material changes in traditional equipment, reducing idle time and waiting time, and thus effectively improving overall production efficiency.

[0055] Example 2

[0056] like Figures 6 to 12 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a first connecting plate 212 is provided on one side of the second connecting plate 213, the first connecting plate 212 is fixedly connected to one side of the lower frame 21, and a second rotating rod 25 is rotatably connected inside the first connecting plate 212. The second rotating rod 25 and the first rotating rod 24 are rotatably and slidably connected inside.

[0057] like Figure 6 As shown, a pressing rod 251 is fixedly connected to the second rotating rod 25, and a protrusion 211 is provided on the outer side of the first rotating rod 24. The protrusion 211 is fixedly connected to the lower frame 21, and a spring member 2121 is fixedly connected to the lower surface of the first connecting plate 212. One end of the spring member 2121 is in contact with one side of the pressing rod 251.

[0058] like Figure 10 and Figure 11 As shown, a limiting rod 263 is fixedly connected to the third rotating rod 26. A limiting groove is provided on the inner wall of the second rotating rod 25. The inside of the limiting groove is slidably connected to one end of the limiting rod 263. The limiting groove includes an initial section 252. A descending section 253 is provided on one side of the initial section 252. An ascending section 254 is provided on one side of the descending section 253. A reset section 255 is provided on one side of the ascending section 254. The groove depth of the descending section 253 is shallower than the depth of the reset section 255. The groove depth of the reset section 255 is shallower than the groove depth of the initial section 252. An elastic ball is provided at one end of the limiting rod 263.

[0059] like Figure 12As shown, the outer circumferential surface of the third rotating rod 26 is provided with an annular groove 261. A sliding rod 2131 is slidably connected in the annular groove 261. One end of the sliding rod 2131 is fixedly connected to the second connecting plate 213. A connecting spring 2132 is fixedly connected between one end of the sliding rod 2131 and the upper surface of the second connecting plate 213. The interior of the third rotating rod 26 is provided with an annular groove 261, which includes an ascending section and a descending section that are alternately and continuously arranged along the circumferential direction. The descending section gradually slopes downward along the circumference of the third rotating rod 26, and the ascending section gradually slopes upward along the circumference of the third rotating rod 26. The sliding rod 2131 is slidably fitted in the annular groove 261 and is used to force the third rotating rod 26 to perform axial reciprocating lifting and lowering motion by the inclined surface thrust of the annular groove 261 when the first rotating rod 24 rotates.

[0060] The outer circumferential surface of the third rotating rod 26 is provided with a longitudinal groove 262 located below the annular groove 261. The dimensions of the sliding rod 2131 are matched with the dimensions of the longitudinal groove 262 and the annular groove 261. The depth of the longitudinal groove 262 is shallower than the depth of the annular groove 261. A movable plate 2133 is slidably connected to the upper surface of the second connecting plate 213. The interior of the movable plate 2133 is slidably connected to one end of the pressing rod 251. An inclined surface 2134 is provided inside the movable plate 2133. One side of the inclined surface 2134 is in contact with one end of the sliding rod 2131.

[0061] Specifically, after the copper wire coil is wound up, due to the elasticity of the copper wire itself and the characteristic of layer-by-layer winding in a staggered pattern, the copper wire is affected by tension during the winding process, and tiny gaps will form between the layers. These gaps accumulate after multiple layers of winding, resulting in a loose overall coil structure. This leads to problems such as loose wire and copper wire falling off during material handling and transportation, requiring manual sorting of loose wire, which increases labor intensity and reduces production efficiency.

[0062] To solve the above technical problems, the present invention uses the following: In the initial state, the limiting rod 263 is at the top of the initial section 252 of the limiting groove, and the sliding rod 2131 is inside the annular groove 261 and supports the third rotating rod 26. When the first rotating rod 24 rotates, the first rotating rod 24 drives the ribs on the surface of the second rotating rod 25 to rotate through the rib groove on its surface, so that the second rotating rod 25 can rotate synchronously with the first rotating rod 24. The second rotating rod 25 drives the limiting rod 263 to rotate through the initial section 252 of the limiting groove. The limiting rod 263 drives the third rotating rod 26 to rotate synchronously. The third rotating rod 26 drives the annular groove 261 to rotate, so that the sliding rod 2131 slides inside the annular groove 261 and supports the third rotating rod 26.

[0063] When the third rotating rod 26 drives the baffle 27 to its final position inside the lower frame 21, the telescopic end of the hydraulic cylinder 23 continues to move and drives the fixed plate 241 and the first rotating rod 24 to rotate synchronously. The first rotating rod 24 drives the second rotating rod 25 to rotate synchronously, so that the second rotating rod 25 drives the pressing rod 251 to move synchronously. When the pressing rod 251 moves to the protrusion 211, the pressing rod 251 drives the second rotating rod 25 to move upward and press the spring member 2121. At the same time, the second rotating rod 25 slides inside the first rotating rod 24 and maintains rotation through the cooperation of the groove and the rib. The second rotating rod 25 carries The initial section 252 of the limiting groove of the moving limiting rod 263 moves upward, causing the limiting rod 263 to move to the interface between the initial section 252 and the descending section 253. At the same time, the pressing rod 251 drives the moving plate 2133 to slide upward inside the second connecting plate 213. The second connecting plate 213 drives the inclined surface 2134 to slide synchronously, causing the connecting spring 2132 to drive the sliding rod 2131 to move. The sliding rod 2131 moves away from the annular groove 261 and releases the limitation on the up and down movement of the third rotating rod 26. At the same time, the sliding rod 2131 moves into the interior of the longitudinal groove 262, which can limit the rotation of the third rotating rod 26.

[0064] Subsequently, the first rotating rod 24 continues to drive the second rotating rod 25 to rotate. The second rotating rod 25 drives the upper and lower sections of the limiting groove to rotate. The descending section 253 and the limiting rod 263 come into contact and press, causing the limiting rod 263 to drive the third rotating rod 26 to move downward. The third rotating rod 26 moves downward and drives the baffle 27 to move downward. Multiple baffles 27 move downward and press down on the coil that has been wound up below the baffles 27. At the same time, the sliding rod 2131 slides in the longitudinal groove 262 on the surface of the third rotating rod 26. The baffle 27 descends and compacts the coil.

[0065] This device drives the third rotating rod 26 to descend, which in turn drives the pressure plate to descend and make full contact with the upper surface of the copper wire coil that has been wound up on the lower surface of the baffle 27, applying uniform downward pressure. This directly squeezes the tiny gaps between the layers of the copper wire coil, thus avoiding the problem of loose wire and copper wire falling off during the material handling and transfer process due to large gaps between the layers of the wound copper wire coil. This would otherwise require manual sorting of loose wire, increasing labor intensity and reducing production efficiency.

[0066] like Figure 6 As shown, an exhaust bracket 271 is fixedly connected to one side of the baffle 27, and the exhaust bracket 271 has a plurality of exhaust holes 272 inside.

[0067] like Figure 8As shown, a piston 214 is provided on the inner side of the third rotating rod 26. The third rotating rod 26 is a hollow tubular structure with a cylinder-type sealed cavity inside. The piston 214 extends coaxially into the sealed cavity and forms a sliding seal with the inner wall of the sealed cavity. One end of the piston 214 is fixedly connected to the lower frame 21. The size of the piston 214 matches the inner wall of the third rotating rod 26. Several exhaust holes are equidistantly opened at the bottom of the third rotating rod 26. An exhaust one-way valve 265 is installed on the inner side of the third rotating rod 26 above the exhaust holes. An intake one-way valve 264 is installed on the side wall of the third rotating rod 26 below the piston 214. A connecting pipe 266 is fixedly connected between one end of the exhaust one-way valve 265 and the interior of the exhaust frame 271.

[0068] Specifically, when the baffle 27 presses down on the copper wire coil, the copper powder particles on the surface of the copper wire have a certain adsorption capacity. The copper powder adheres to the lower surface of the baffle 27 and accumulates continuously as the baffle 27 runs. If it is not actively cleaned, the baffle 27 will cause wear on the surface of the copper wire coil when it presses down, thus causing a decrease in the forming quality of the copper wire coil.

[0069] To solve the above technical problems, the device is used as follows: When the third rotating rod 26 moves downward and the position of the piston 214 remains unchanged, a negative pressure is formed in the internal sealed cavity of the third rotating rod 26. The negative pressure draws in pure gas through the intake one-way valve 264 and into the interior of the third rotating rod 26. The intake one-way valve 264 can be connected to pure air through a hose, which is not shown in the figure of this device. When the limiting rod 263 moves to the interface between the descending section 253 and the ascending section 254, the baffle 27 descends to the final position. Then the second rotating rod 25 continues to rotate, causing the limiting rod 263 to move into the interior of the ascending section 254 of the limiting groove. At this time, the third rotating rod 26 drives the baffle 27 to move upward, and the position of the piston 214 remains unchanged. Therefore, the internal volume of the sealed cavity is reduced, so that the internal gas is discharged through the exhaust one-way valve 265 into the interior of the connecting pipe 266, and enters the interior of the exhaust frame through the connecting pipe 266. Finally, it is discharged through the exhaust hole on the exhaust frame. The exhaust hole can then purge the lower surface of the baffle 27.

[0070] When the baffle 27 needs to be unfolded to the outside of the lower frame 21, the limiting rod 263 slides to the initial section 252 in the reset section 255. At this time, the third rotating rod 26 will not rise or fall and will maintain the stability of the unfolding.

[0071] This device utilizes the upward movement of the third rotating rod 26 to pneumatically clean the copper powder adhering to the lower surface of the baffle 27 through the pneumatic cooperation of the sealed cavity and piston 214. This keeps the lower surface of the baffle 27 clean, eliminating the need for manual wiping to remove the copper powder. At the same time, it avoids the problem of copper powder adhering to the lower surface of the baffle 27 causing wear on the surface of the copper wire coil when it is pressed down, thus preventing a decrease in the forming quality of the copper wire coil.

[0072] Working principle: Before using the device, the distance of the moving rod 221 is adjusted. The moving rod 221 drives the stop rod 222 to slide inside the upper frame 22, which can form a winding space suitable for the copper rod to form a plum blossom coil. When the winding operation is required, the winding device on one side of the winding mechanism 3 is opened to start working. The winding device rotates and drives the copper wire to rotate. It is positioned in a plum blossom shape by the winding mechanism 3 and guided and constrained by the stop rod 222. The copper rod begins to be wound in a plum blossom shape on the placement plate 42. As the steel coil is gradually wound and the height gradually changes, the lifting plate 41 can be driven to descend to adapt to the height change of the steel coil. At this time, the stop plate 27 is on the outside of the outer frame.

[0073] When the coil on the placement plate 42 is wound up to a certain height and the staff needs to perform material handling, the hydraulic cylinder 23 can be opened to work. The extension end of the hydraulic cylinder 23 drives the fixed plate 241 and the first rotating rod 24 to rotate. The fixed plate 241, through the cooperation of the connecting rod 231, enables multiple fixed plates 241 and the first rotating rod 24 to rotate synchronously.

[0074] In the initial state, the limiting rod 263 is at the top of the initial section 252 of the limiting groove, and the sliding rod 2131 is inside the annular groove 261 and supports the third rotating rod 26. When the first rotating rod 24 rotates, the first rotating rod 24 drives the ribs on the surface of the second rotating rod 25 to rotate through the rib groove on its surface, so that the second rotating rod 25 can rotate synchronously with the first rotating rod 24. The second rotating rod 25 drives the limiting rod 263 to rotate through the initial section 252 of the limiting groove. The limiting rod 263 drives the third rotating rod 26 to rotate synchronously. The third rotating rod 26 drives the annular groove 261 to rotate, so that the sliding rod 2131 slides inside the annular groove 261 and supports the third rotating rod 26.

[0075] When the third rotating rod 26 drives the baffle 27 to its final position inside the lower frame 21, the telescopic end of the hydraulic cylinder 23 continues to move and drives the fixed plate 241 and the first rotating rod 24 to rotate synchronously. The first rotating rod 24 drives the second rotating rod 25 to rotate synchronously, so that the second rotating rod 25 drives the pressing rod 251 to move synchronously. When the pressing rod 251 moves to the protrusion 211, the pressing rod 251 drives the second rotating rod 25 to move upward and press the spring member 2121. At the same time, the second rotating rod 25 slides inside the first rotating rod 24 and maintains rotation through the cooperation of the groove and the rib. The second rotating rod 25 carries The initial section 252 of the limiting groove of the moving limiting rod 263 moves upward, causing the limiting rod 263 to move to the interface between the initial section 252 and the descending section 253. At the same time, the pressing rod 251 drives the moving plate 2133 to slide upward inside the second connecting plate 213. The second connecting plate 213 drives the inclined surface 2134 to slide synchronously, causing the connecting spring 2132 to drive the sliding rod 2131 to move. The sliding rod 2131 moves away from the annular groove 261 and releases the limitation on the up and down movement of the third rotating rod 26. At the same time, the sliding rod 2131 moves into the interior of the longitudinal groove 262, which can limit the rotation of the third rotating rod 26.

[0076] Subsequently, the first rotating rod 24 continues to drive the second rotating rod 25 to rotate, and the second rotating rod 25 drives the upper and lower sections of the limiting groove to rotate. The descending section 253 and the limiting rod 263 come into contact and squeeze, causing the limiting rod 263 to drive the third rotating rod 26 to move downward. The third rotating rod 26 moves downward and drives the baffle 27 to move downward. Multiple baffles 27 move downward and press down on the coil that has been wound up below the baffles 27. At the same time, the sliding rod 2131 slides in the longitudinal groove 262 on the surface of the third rotating rod 26, and the baffle 27 descends and compacts the coil.

[0077] When the third rotating rod 26 moves downward and the position of the piston 214 remains unchanged, a negative pressure is formed in the internal sealed cavity of the third rotating rod 26. The negative pressure draws in pure gas through the intake one-way valve 264 and into the interior of the third rotating rod 26. The intake one-way valve 264 can be connected to pure air through a hose, which is not shown in the figure of this device. When the limiting rod 263 moves to the interface between the descending section 253 and the ascending section 254, the baffle 27 descends to its final position. Then the second rotating rod 25 continues to rotate, causing the limiting rod 263 to move into the interior of the ascending section 254 of the limiting groove. At this time, the third rotating rod 26 drives the baffle 27 to move upward, and the position of the piston 214 remains unchanged. Therefore, the internal volume of the sealed cavity decreases, allowing the internal gas to be discharged through the exhaust one-way valve 265 into the interior of the connecting pipe 266, and then into the interior of the exhaust frame through the connecting pipe 266. Finally, it is discharged through the exhaust hole on the exhaust frame, which can then purge the lower surface of the baffle 27.

[0078] When the baffle 27 needs to be unfolded to the outside of the lower frame 21, the limiting rod 263 slides to the initial section 252 in the reset section 255. At this time, the third rotating rod 26 will not rise or fall and will maintain the stability of the unfolding. Then, each structure will be reset to the initial state and can be used multiple times in the future.
