Its performance directly affects the subsequent processing quality.

[0003] Currently, mainstream equipment generally uses roller hard extrusion bending to change the conveying direction of steel coils, that is, through small-angle bending, the steel coils are forced to be guided to a straight line for conveying. However, this method has significant defects: on the one hand, the rigid contact between the metal rollers and the steel coils leads to an excessively high friction coefficient, especially for materials with high surface requirements such as stainless steel and galvanized sheets, which can easily cause scratches, indentations or coating peeling in the extrusion area; on the other hand, hard bending will trigger a sudden release of residual stress in the coiling, causing dislocation between the layers of the steel coil or overall twisting deformation, while existing solutions (such as surface chrome-plated rollers or polyurethane coatings) can only reduce friction to a limited extent, and cannot fundamentally eliminate the coupling damage of mechanical forced deformation and dynamic stress out of control.

The present invention provides a correction component; during the conveying process of the steel coil, the edges on both sides thereof are in contact with each other.

DETAILED DESCRIPTION

[0020] The specific embodiments of the present invention are described in detail below, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0021] See also Figure 1 、 Figure 2 and Figure 3 The present invention provides a stainless steel coil feeder, comprising a base 101, a supporting mechanism for supporting a steel coil 4 is provided in the middle of the base 101, the supporting mechanism comprising a driving motor 104, an output end of the driving motor 104 being fixedly connected to a supporting column 105, the driving motor 104 drives the supporting column 105 to rotate, thereby driving the steel coil 4 to rotate, thereby assisting in feeding the steel coil 4; Since the size of the cavity inside the steel coil 4 will change due to the model of the steel coil 4 or the degree of unwinding of the steel coil 4, in order to achieve stable support for the steel coil 4, the support column 105 of the present application is fixedly installed with a plurality of pushing hydraulic cylinders 106, and the output ends of the plurality of pushing hydraulic cylinders 106 are fixedly connected to support plates 107, and one side of the plurality of support plates 107 is set as an arc surface, and the plurality of arc surfaces are mutually enclosed to form a cylindrical shape, and the support plates 107 are driven out by the pushing hydraulic cylinders 106 to adjust the size of the enclosed space of each support plate 107, thereby achieving stable contact support for steel coils 4 with different inner cavity sizes; the pushing hydraulic cylinders 106 of the present application are independently controlled, and then the pushing hydraulic cylinders 106 can act alternately to drive the support plates 107 to impact the steel coil 4 The impact contact allows the steel coil 4 to gradually loosen due to vibrations in different directions during the uncoiling and feeding process, so that the mechanical stress generated by the steel coil 4 during the winding process can be gradually guided and released, avoiding the problem of deformation and distortion of the steel coil 4 caused by the concentrated release of stress at the uncoiling and feeding end. Specifically, the output end of the drive motor 104 is fixedly connected to the supporting column 105 through the adapter column, and the middle part of the adapter column is rotatably installed with an oil supply sleeve 108. One side of the oil supply sleeve 108 is connected to the hydraulic power component, and an oil channel is opened in the inner cavity of the adapter column. The oil channel is close to the inner cavity of the oil supply sleeve 108 at one end, and is connected to the hydraulic cylinder 106 through the oil distribution pipe 109 and the other end of the oil channel. A control valve 110 is fixedly installed in the middle of each oil distribution pipe 109 to achieve control of each push hydraulic cylinder.

[0022] Since the present invention feeds the steel coil 4 during the unwinding stage by means of pre-continuous vibration, the steel coil 4 is naturally unwound. Therefore, compared with the traditional method of tightly winding the steel coil 4 and unwinding it by pulling it from one end, the steel coil 4 of the present invention will naturally unwind and occupy a larger space after unwinding. Therefore, in order to realize the feeding of the unwound steel coil 4, please refer to Figure 1 In the present application, an unfolding mechanism 2 is provided on one side of the base 101, and the unfolding mechanism 2 includes an unfolding frame 201. An arc-shaped guide trough 202 is provided on one side of the unfolding frame 201 close to the supporting column 105. The arc-shaped guide trough is used to guide and limit the protruding part of the steel coil 4 after unfolding. Compared with the existing method of using a roller to hard squeeze and change the conveying direction of the steel coil 4 by bending at a small angle to make it conveyed in a straight line, the present application adopts an arc-shaped guide trough 202, which can conform to the natural unfolding shape of the steel coil 4, avoid damage to the steel coil 4 caused by hard squeezing and bending the steel coil 4, and reduce the resistance of the steel coil 4 during transportation.

[0023] See also Figure 1 and Figure 2Due to the continuous vibration and loosening during the unwinding stage of the present invention, the steel coil 4 is in a naturally loose and unfolded state when entering the arc-shaped guide trough 202. Therefore, it may be deflected in the horizontal direction due to the influence of internal stress or external forces during the transportation process. For the deflection mode, please refer to Figure 10 (b) To prevent such deflection from affecting the conveying operation and the subsequent processing of the steel coil 4, the present application has several deflection correction components 203 fixedly installed on both sides of the arc-shaped guide trough 202. Figure 5 The correction component 203 includes a correction frame 2031, and a movable groove 2032 is opened in the middle of several correction frames 2031. The inner part of the movable groove 2032 is slidably connected to the guide wheel frame 2033. The side of the guide wheel frame 2033 close to the middle of the arc-shaped guide trough 202 is rotatably connected to the correction guide wheel 2034. One end of the inner wall of the movable groove 2032 is fixedly installed with a linear motor 2035. The output end of the linear motor 2035 is fixedly connected to the guide wheel frame 2033 through a connecting rod. A tension sensor 2036 for detecting the force between the steel coil 4 and the guide wheel is fixedly installed in the middle. By arranging correcting guide wheels 2034 on both sides of the arc-shaped guide trough 202, the edges on both sides of the steel coil 4 are fitted and contacted during the transportation of the steel coil 4. When the steel coil 4 belt is tilted, the pressure from the steel coil 4 on the correcting guide wheel 2034 in contact with it will increase, thereby driving the reading of the tension sensor 2036 to change, thereby realizing real-time detection of the tilt state of the steel coil 4.

[0024] In one embodiment, see Figure 5 In order to adjust the horizontal position of the steel coil 4, one side of the base 101 of the present application is fixedly connected to a mounting frame, and an adjusting hydraulic cylinder 103 is fixedly installed inside the mounting frame. The output end of the adjusting hydraulic cylinder 103 is fixedly connected to the support column 102, and one end of the support column 102 is fixedly connected to the driving motor 104. The support column 102 is driven to move by adjusting the hydraulic cylinder 103, and then the supporting column 105 connected thereto is driven to move, thereby changing the horizontal relative distance between the steel coil 4 and the unfolding frame 201 thereon, thereby changing the reading of the tension sensor 2036 in contact therewith, and correcting the inclination angle of the steel coil 4 in the arc guide trough 202 by moving the position of the steel coil 4, so as to avoid the problem that the inclination angle of the end of the steel coil 4 in the arc guide trough 202 is too large, which causes excessive conveying resistance or jamming. For details, please refer to Figure 10 , Figure 10 (a) shows that the steel coil 4 is not tilted. At this time, the steel coil 4 is in a normal conveying state. The portion of the steel coil 4 inside the unrolling frame 201 is also in a horizontal state. The edges on both sides are in normal contact with the correcting guide wheels 2034 on both sides. Figure 10(b) shows that the steel coil 4 has tilted due to stress. At this time, the steel coil 4 inside the unfolding frame 201 is also in a tilted state. The contact force between one side of the steel coil 4 and the correcting guide wheel 2034 is significantly greater than that on the other side. When the pressure difference between the correcting guide wheels 2034 on both sides exceeds the preset range, the adjustment action of the adjustment hydraulic cylinder 103 is triggered, and the adjustment hydraulic cylinder 103 drives the supporting column 105 and the steel coil 4 to shift horizontally as a whole. At this time, the state is referred to Figure 10 (c) By shifting the steel coil 4 on the supporting column 105 to a certain extent, the posture of the steel coil 4 inside the unfolding frame 201 is corrected and compensated to a certain extent; in specific implementation, an adjustment mechanism can also be set on the supporting column 102, so that the supporting column 102 can be rotated and tilted in the moving direction to improve the flexibility of the position of the steel coil 4.

[0025] In one embodiment, see Figure 2 and Figure 4 After the steel coil 4 is guided and sent out by the unfolding frame 201, it enters the horizontal conveying stage. During this process, in order to limit the steel coil 4, a loading mechanism 3 is set below the supporting column 105. The loading mechanism 3 includes a loading platform 301, a lifting plate 302 is set on the top of the loading platform 301, and a number of limiting columns 3031 are rotatably installed on both sides of the top of the lifting plate 302. A through slot 208 is opened at one end of the unfolding frame 201 near the limiting column 3031. The through slot 208 corresponds to the bottom end of the arc-shaped guide trough 202. The steel coil 4 entering the arc-shaped guide trough 202 passes through the through slot 208. Please refer to Figure 7 The outer wall of the limiting column 3031 is provided with a plurality of limiting grooves 3032, and a baffle 3033 is fixedly connected to both sides of the plurality of limiting grooves 3032. The steel coil 4 is limited by the cooperation of the limiting grooves 3032 and the baffle 3033, and the steel coil 4 is leveled and corrected to a certain extent by the push of the plurality of limiting grooves 3032 and the baffle 3033; the inner wall of the limiting groove 3032 is engaged with a contact piece, which is made of flexible rubber material to avoid damage caused by direct contact between the edge of the steel coil 4 and the inner wall of the limiting groove 3032. At the same time, the rubber is used to increase the friction between the contact piece and the inner wall of the limiting groove 3032, so that the limiting column 3031 can rotate with the movement of the steel coil 4; in specific implementation, the contact piece of different diameters can be used according to the actual width of the steel coil 4. The diameter of the contact piece cannot be larger than the diameter of the baffle 3033, so as to ensure effective limitation of the steel coil 4.

[0026] In one embodiment, see Figure 7 and Figure 8, one side of the plurality of limit posts 3031 is provided with an adjusting member 308 for adjusting the rotation speed of the limit posts 3031, the adjusting member 308 includes a device box 3081, one side of the device box 3081 is fixedly installed with an encoder 3082 for detecting the rotation distance of the limit posts 3031, an electric push rod 3083 is fixedly installed inside the device, the output end of the electric push rod 3083 is fixedly connected to a pressing block 3084, one side of the pressing block 3084 is in close contact with the limit post 3031, and by setting the encoder 30 82 detects the rotation speed of the limit column 3031. When the rotation speed of the limit column 3031 at the local position is too fast, that is, the movement distance of the steel coil 4 toward one side of the limit column 3031 is greater than the other side, it is judged that the steel coil 4 is tilted toward the side of the limit column 3031 that is transported too fast. At this time, the clamping block 3084 is pushed by the electric push block to contact the limit column 3031, thereby increasing the rotation resistance of the limit column 3031, and then increasing the contact resistance between the steel coil 4 and the limit column 3031, and correcting the tilt of the steel coil 4.

[0027] In one embodiment, to facilitate the loading operation of the steel coil 4, please refer to Figure 6 and Figure 7 In this application, a loading rack 306 is arranged above the lifting plate 302. Several supporting rollers 307 are rotatably installed on the top of the loading rack 306. The two ends of the loading rack 306 are lifted upward. The existence of the loading rack 306 and the supporting rollers 307 is used to limit the steel coil 4. The rotation of the supporting rollers 307 is used to assist in the rotation and displacement of the steel coil 4, so that the end part of the steel coil 4 can be directed towards the unfolding rack 201, which facilitates the unfolding and loading operation of the steel coil 4.

[0028] In one embodiment, see Figure 7 In order to provide power for the lifting and moving of the steel coil 4, a lifting and loading component 309 is provided inside the loading platform 301, and the output end of the lifting and loading component 309 is fixedly connected to the lifting plate 302, and the top corners of the lifting plate 302 are fixedly connected to the bottom of the loading rack 306 through connecting columns, and several limiting columns 3031 are rotatably connected to the connecting columns; the lifting and loading component 309 is a lifting hydraulic cylinder or a shear lifting frame. In this embodiment, a shear lifting frame is used as the power; since the lifting and loading component 309 can drive the lifting plate 302 and the loading rack 306 to perform lifting operations synchronously, and structures such as the limiting columns 3031 are arranged on the lifting plate 302, the position of the limiting columns 3031 can be changed by adjusting the lifting position of the lifting frame, thereby further realizing the adjustment of the direction and position of the steel coil 4 sent out by the through slot 208, and then realizing the correction of the sending posture of the steel coil 4, so that it can realize the feeding operation according to the required sending height and sending direction.

[0029] In one embodiment, see Figure 7 and Figure 9The cam 3042 of the lifting plate 302 is fixed on the upper surface of the lifting plate 302, and the cam 3043 of the lifting plate 302 is fixed on the upper surface of the lifting plate 302.

[0030] In one embodiment, see Figure 9 For the correction and adjustment of the middle part of the steel coil 4, a jacking assembly 305 is provided in the middle of the inner wall of the mounting groove 3041 of the present application. The jacking assembly 305 includes a jacking hydraulic cylinder 3051, and the output end of the jacking hydraulic cylinder 3051 is fixedly connected to the jacking frame 3052, and the internal rotatable installation of the jacking roller 3053 is used to drive the jacking frame 3052 and the jacking roller 3053 to be lifted, so as to realize the jacking correction of the middle part of the steel coil 4, and also to assist the respective limit columns 3031 on both sides to support the middle part of the steel coil 4 during the transportation process. By flexibly adjusting the height of the jacking roller 3053, the need for adjusting the tension degree of the steel coil 4 during the transportation process is met.

[0031] In one embodiment, see Figure 4 In order to further eliminate the residual stress of the steel coil 4 itself, the present application considers heating the steel coil 4 during the conveying stage so that the stress is slowly released. Specifically, a hot air hood 204 is fixedly installed on the bottom of the inner wall of the arc-shaped material guide trough 202 of the present application, and a plurality of hot air outlets 205 are opened on the top of the hot air hood 204. An electric heater 209 is fixedly installed inside the hot air hood 204, and a hot air pipe 207 is fixedly connected to one side of the hot air hood 204. One end of the hot air pipe 207 is fixedly connected to the output end of an external air pump. Through the hot air pipe 207 and the hot air outlet 205 and other structures, air is supplied to the steel coil 4 passing through the arc-shaped material guide trough 202 for heating.

[0032] In one embodiment, further, several heating zones with different temperatures are formed in the arc-shaped material guide trough 202, and several partition plates 206 are fixedly connected to the interior of the hot air hood 204. The several partition plates 206 divide the inner cavity of the hot air hood 204 into several hot air zones. Several diversion pipes are fixedly connected to one side of the several hot air zones, and one side of the several diversion pipes is connected to the hot air pipe 207. Regulating valves are fixedly installed in the middle of the several diversion pipes. The electric heaters 209 in different hot air zones are independently controlled. By adjusting the power of the electric heater 209 and the air inlet flux of each regulating valve, the air flow rate and temperature delivered from each hot air zone can be adjusted.

[0033] See also Figures 1 to 9 A method for using a stainless steel coil feeder comprises the following steps: Step one: load the steel coil 4 onto the supporting mechanism, and drive the supporting plate 107 to move out through the work of multiple push hydraulic cylinders 106 to achieve a tight limit on the inner cavity of the steel coil 4; Step 2: The driving motor 104 rotates to drive the support column 102 and the supporting column 105 to rotate, so that the end of the steel coil 4 faces the unrolling frame 201 to facilitate unrolling; Step 3: Manually pull one end of the unrolled steel coil 4 around the arc-shaped guide trough 202 and out through the through slot 208. The coil then passes through the limiting slot 3032 and out. The turning motor drives the turning frame 3042 to rise, and the contact rollers 3044 support and limit the bottom of the steel coil 4. Step 4: Control the push hydraulic cylinders 106 to start working alternately through the control valve 110, driving the support plate 107 to contact and impact the steel coil 4, thereby vibrating and loosening the steel coil 4; Step 5: The drive motor 104 operates slowly to rotate the unwound steel coil 4, causing it to slowly enter the arc-shaped guide trough 202, completing a continuous and stable feeding operation; Step 6: The electric heater 209 is started to heat each hot air zone, and hot air is sent to the steel coil 4 through the hot air outlet 205 to eliminate the residual stress of the steel coil 4; Step 7: By adjusting the position of the lifting frame, the position of the limit column 3031 is changed to correct the feeding posture of the steel coil 4 so that it can be fed according to the required feeding height and feeding direction.

[0034] When the present invention is in use, the steel coil 4 is hoisted and moved and placed on the loading rack 306 through the external loading equipment, and the lifting loading component 309 is started to drive the lifting plate 302 and the loading rack 306 to rise until the inner cavity position of the steel coil 4 corresponds to the position of the supporting column 105, and then the adjusting hydraulic cylinder 103 drives the supporting column 102 to be pushed out, and then drives the supporting column 105 to extend and penetrate into the cavity of the steel coil 4 to support the steel coil 4, and then the hydraulic oil is connected to the oil supply sleeve 108 and transported into the oil channel. The control valves 110 on each oil distribution pipe 109 are opened, so that the pushing hydraulic cylinder 106 drives the supporting plate 107 to move to tighten and limit the inner cavity of the steel coil 4, thereby completing the loading of the steel coil 4; The rotation of the drive motor 104 drives the support column 102 and the supporting column 105 to rotate, so that the end of the steel coil 4 is directed to the unfolding frame 201 to facilitate unfolding; the unfolded steel coil 4 is manually pulled to bypass the arc guide trough 202 and then sent out from the through slot 208, so that the two sides of the steel coil 4 are respectively sent out from the limiting columns 3031 on both sides through the limiting slot 3032, and the turning frame 3042 is lifted by the turning motor, and the contact rollers 3044 are used to support and limit the two sides of the bottom of the steel coil 4; then the control valve 110 controls the pushing hydraulic cylinder 106 to start working alternately, driving the supporting plate 107 to contact and impact the steel coil 4, and vibrating and unwinding the steel coil 4; the drive motor 104 slowly rotates to drive the supporting column 105 and the supporting arc plate, and then drives the unwound steel coil 4 to rotate, so that it slowly enters the arc guide trough 202, and cooperates with the subsequent traction of the steel coil 4 processing equipment to drive the steel coil 4 to move, completing a continuous and stable feeding operation; During the conveying process of the steel coil 4, the edge of the portion thereof located in the arc-shaped conveying trough contacts with the deflection-correcting guide wheels 2034 on both sides. When the steel coil 4 tilts due to its own stress, a difference will be generated in the readings of the tension sensors 2036 connected to the deflection-correcting guide wheels 2034 on both sides. When the difference is greater than the set value, the support column 102 is driven to move by adjusting the hydraulic cylinder 103, thereby driving the supporting column 105 connected thereto to move, thereby changing the horizontal relative distance between the steel coil 4 and the unfolding frame 201 thereon. By moving the position of the steel coil 4, the inclination angle of the steel coil 4 in the arc-shaped guide trough 202 is corrected, thereby changing the readings of the tension sensors 2036 in contact therewith, until the difference in the readings of the tension sensors 2036 on both sides falls within the set value range. When the steel coil 4 passes through the arc-shaped guide trough 202, the external air pump is activated to transport the hot air to each hot air zone through the hot air pipe 207 and the diversion pipe. The electric heater 209 is activated to heat each hot air zone. Hot air is then sent to the steel coil 4 through the hot air outlet 205, thereby gradually heating the steel coil 4 and eliminating residual stress in the steel coil 4. When the steel coil 4 passes through the limiting groove 3032, the edge of the steel coil 4 contacts the contact piece, thereby driving the limiting column 3031 to rotate. The encoder 3082 in the adjustment member 308 detects the rotation distance of the limiting column 3031. When the rotation distance deviation of the limiting columns 3031 on both sides is too large, it is determined that the steel coil 4 is in an inclined conveying state. At this time, the electric push block pushes the pressing block 3084 to contact the limiting column 3031, thereby increasing the rotation resistance of the limiting column 3031, thereby increasing the contact resistance between the steel coil 4 and the limiting column 3031, and correcting the inclination of the steel coil 4. At the same time, the turning motor drives the turning frame 3042 to be lifted, and the contact roller 3044 is used to support and limit the two sides of the bottom of the steel coil 4. By adjusting the lifting position of the lifting frame, the position of the limit column 3031 is changed to realize the correction of the delivery posture of the steel coil 4, so that it can be fed according to the required delivery height and delivery direction. The lifting hydraulic cylinder 3051 can also be used to drive the lifting frame 3052 to be lifted and moved as needed, so that the lifting roller 3053 contacts the bottom surface of the steel coil 4, thereby realizing auxiliary support for the steel coil 4 and meeting the need to adjust the tension of the steel coil 4.
