Self-compensating deviation prevention mechanism for high-speed slitting of aluminum strip

Abstract

The application relates to the technical field of high-speed slitting of aluminum strips, in particular to a self-compensation deviation-preventing mechanism for high-speed slitting of aluminum strips. When the aluminum strip deviates before high-speed slitting, the deviation rectification starting assembly is used to start the deviation rectification clamping mechanism, so that the aluminum strip is clamped and limited under the action of the deviation rectification clamping mechanism, and the convenient conveying of the aluminum strip is not affected under the action of the clamping roller in the middle of the deviation rectification clamping mechanism; then the deviation rectification starting assembly is used to start the deviation rectification adjusting mechanism, so that the synchronous and same-direction movement of the two sides of the clamped aluminum strip is realized under the action of the deviation rectification adjusting mechanism, thereby realizing the self-compensation deviation rectification of the aluminum strip. Since the aluminum strip is rectified through the adjusting mode of synchronous clamping on both sides and then rectification, the disadvantage that the aluminum strip is unevenly stressed on both sides due to unilateral pushing rectification is avoided, and the deviation rectification quality of the aluminum strip in the high-speed slitting process is improved.

Description

Technical Field

[0001] This application relates to the field of high-speed aluminum strip slitting technology, and in particular to a self-compensating anti-deviation mechanism for high-speed aluminum strip slitting. Background Technology

[0002] After being rolled, aluminum strip is wound into wide master coils for supply to various industries. To ensure that the aluminum strip meets the needs of these industries, a slitting machine is used to cut the master coil aluminum strip at high speed. During the high-speed slitting process, the aluminum strip needs to be corrected to ensure the quality of the slitting result.

[0003] The existing high-speed aluminum strip slitting correction mechanism mainly consists of correction sensors installed on both sides of the aluminum strip and a correction pushing mechanism installed on one side of the correction sensors. When the aluminum strip deviates before high-speed slitting, the correction sensor sends information to the external controller so that the correction pushing mechanism can be activated under the action of the external controller, and then the aluminum strip is corrected by pushing on one side.

[0004] While existing high-speed aluminum strip slitting correction mechanisms can correct the aluminum strip's deviation, the unilateral pushing method during correction causes uneven force distribution on both sides of the aluminum strip. This results in curling and twisting deformation of the aluminum strip after correction, leading to poor correction quality during high-speed slitting. Summary of the Invention

A deviation correction adjustment mechanism is also mounted on the support platform on one side of the bracket. The deviation correction adjustment mechanism includes a slide groove, a second motor, a threaded rod, and two sliders symmetrically mounted on the threaded rod. Each slider is equipped with a deviation correction clamping mechanism, which includes a third motor, a mounting plate, a clamping roller, a clamping plate, and a bidirectional threaded rod. A deviation correction starting assembly is mounted on the support platform on one side of the deviation correction clamping mechanism. The deviation correction starting assembly includes a first spring, a telescopic rod, a first pressure block, a deviation correction clamping switch, a deviation correction adjustment switch, a vertical plate, a slide column, a second spring, a second pressure block, and a linkage plate. A guide mechanism is also mounted on the support platform on one side of the deviation correction starting assembly.

[0007] Optionally, the high-speed slitting mechanism includes an electric push rod, a guide column, a slitting shaft, a motor, and a slitting roller. The electric push rod is installed at the center of the top of the bracket. The slitting shaft is connected to the telescopic part of the electric push rod via its own frame. The motor is installed at the power input end of the slitting shaft. The guide column is installed on both sides of the top of the frame of the slitting shaft and is slidably connected to the bracket. The slitting roller is rotatably installed inside the bracket and located below the slitting shaft.

[0008] Optionally, the guiding mechanism includes a pressure roller, an electric actuator, and a guide roller. The guide roller is rotatably mounted on a pre-set support plate on the support platform. The pressure roller is located above the guide roller, and the electric actuator is installed between the pressure roller and the guide roller.

[0009] Optionally, a touch panel is also installed in the middle of the outer side wall of the bracket, and the touch panel integrates control circuitry and a control chip.

[0010] Optionally, the slide groove is formed on the support platform, the threaded rod is driven and installed in the slide groove, the threaded rod passes through the slider and is threadedly connected to the slider, and the second motor is installed outside the support platform and directly opposite the threaded rod.

[0011] Optionally, the mounting plate is welded to the slider, the mounting plate has a T-shaped structure, the motor is mounted at the top center of the mounting plate, the bidirectional threaded rod is connected to the power output end of the motor, and the mating parts of the mounting plate, the clamping plate, and the bidirectional threaded rod are all concave structures.

[0012] Optionally, the clamping plate is threadedly connected to the bidirectional threaded rod, the clamping roller is rotatably engaged with the clamping plate, and the upper and lower sides of the clamping roller extend out of the clamping plate.

[0013] Optionally, the upright plate is welded to the support platform, and each upright plate is slidably mounted with the sliding column in a vertically symmetrical manner. The end of the sliding column facing away from the upright plate is connected to the linkage plate, and the second spring is also installed between the linkage plate and the upright plate on the outside of the sliding column.

[0014] Optionally, the telescopic rod is installed on the upper side wall of the linkage plate facing the vertical plate, the telescopic part of the telescopic rod is connected to the first pressure block, the correction clamping switch is installed on the vertical plate opposite the pressure block, the first spring is also installed between the first pressure block and the linkage plate, the telescopic rod passes through the first spring, the second pressure block is installed on the linkage plate below the pressure block, and the correction adjustment switch is installed on the vertical plate opposite the second pressure block.

[0015] In summary, this application includes at least one of the following beneficial technical effects: This invention, through the coordinated design of a correction initiation component, a correction adjustment mechanism, and a correction clamping mechanism, enables the correction clamping mechanism to be activated first when the aluminum strip deviates before high-speed slitting. This clamping mechanism clamps and limits the aluminum strip, while the clamping rollers in the middle of the correction clamping mechanism do not affect the convenient transport of the aluminum strip. Then, the correction adjustment mechanism is activated by the correction initiation component, enabling the aluminum strip to move synchronously and in the same direction on both sides after clamping. This achieves self-compensating correction of the aluminum strip. Because this correction method corrects the aluminum strip by adjusting the synchronous clamping on both sides, it avoids the disadvantage of uneven force on both sides of the aluminum strip caused by single-sided pushing correction. This reduces the curling and twisting of the aluminum strip during the correction process, thus improving the correction quality of the aluminum strip during high-speed slitting.

[0018] The present application will be further described in detail below with reference to the accompanying drawings.

[0019] To better understand the technical solutions presented in the embodiments of this application, the structure and working principle of the existing high-speed aluminum strip cutting correction mechanism will first be introduced.

[0020] The existing high-speed aluminum strip slitting correction mechanism mainly consists of correction sensors installed on both sides of the aluminum strip and a correction pushing mechanism installed on one side of the correction sensors. When the aluminum strip deviates before high-speed slitting, the correction sensor sends information to the external controller so that the correction pushing mechanism can be activated under the action of the external controller, and then the aluminum strip is corrected by pushing on one side.

[0021] Please see Figures 1-4 This application discloses a self-compensating anti-deviation mechanism for high-speed aluminum strip slitting, comprising a support platform 3, a bracket 1 mounted on one side of the top of the support platform 3, a high-speed slitting mechanism 5 mounted on the bracket 1, and a deviation correction adjustment mechanism 6 mounted on the support platform 3 on one side of the bracket 1. The deviation correction adjustment mechanism 6 includes a slide groove 61, a motor 62, a threaded rod 63, and two sliders 64, which are symmetrically mounted on the threaded rod 63. Each slider 64 is equipped with a deviation correction clamping mechanism 7. The correction clamping mechanism 7 includes a motor 71, a mounting plate 72, a clamping roller 73, a clamping plate 74, and a bidirectional threaded rod 75. A correction starting assembly 8 is installed on one side of the correction clamping mechanism 7 on the support platform 3. The correction starting assembly 8 includes a spring 81, a telescopic rod 82, a pressure block 83, a correction clamping switch 84, a correction adjustment switch 85, a vertical plate 86, a sliding column 89, a spring 87, a pressure block 810, and a linkage plate 88. A guide mechanism 4 is also installed on one side of the correction starting assembly 8 on the support platform 3.

[0022] Specifically, when the aluminum strip deviates before high-speed slitting, the aluminum strip exerts a lateral force on the linkage plate 88. After being subjected to the force by the aluminum strip, the linkage plate 88 moves towards the side closer to the vertical plate 86 under the action of the sliding column 89. As the linkage plate 88 approaches the vertical plate 86, it first presses the pressure block 83 onto the correction clamping switch 84, so that the motor 71 in the correction clamping mechanism 7 is started. After the motor 71 is started, it will bring the two clamping plates 74 closer together under the action of the bidirectional threaded rod 75. As the two clamping plates 74 approach each other, they will use the clamping roller 73 to hold the aluminum strip closer together. The two sides are clamped together without affecting the normal conveying and cutting of the aluminum strip. As the linkage plate 88 moves closer to the vertical plate 86, the telescopic rod 82 will retract. At this time, the spring 81 is compressed. When the pressure block 810 contacts the correction adjustment switch 85, the motor 62 in the correction adjustment mechanism 6 will start. After the motor 62 starts, the threaded rod 63 will rotate. After the threaded rod 63 rotates, the two sliders 64 will move synchronously in the same direction under the action of thread transmission. Thus, while the sliders 64 move, the clamping mechanism is used to synchronously adjust and correct the two sides of the aluminum strip.

[0023] Please see Figures 1-2 The high-speed slitting mechanism 5 includes an electric push rod 51, a guide column 52, a slitting shaft 53, a motor 54, and a slitting roller 55. The electric push rod 51 is installed at the top center of the bracket 1. The slitting shaft 53 is connected to the telescopic part of the electric push rod 51 through its own frame. The motor 54 is installed at the power input end of the slitting shaft 53. The guide column 52 is installed on both sides of the top of the frame of the slitting shaft 53 and is slidably connected to the bracket 1. The slitting roller 55 is rotatably installed in the bracket 1 and located below the slitting shaft 53.

[0024] In one implementation, when the aluminum strip is conveyed to the slitting roller 55, the slitting shaft 53 is pressed onto the aluminum strip on the slitting roller 55 by the electric push rod 51, thereby achieving high-speed slitting of the aluminum strip during the rotation of the slitting shaft 53 driven by the motor 54.

[0025] Please see Figures 1-2 The guiding mechanism 4 includes a pressure roller 41, an electric actuator 42, and a guide roller 43. The guide roller 43 is rotatably mounted on a pre-set support plate on the support platform 3. The pressure roller 41 is located on the upper side of the guide roller 43, and the electric actuator 42 is installed between the pressure roller 41 and the guide roller 43.

[0026] In one implementation, the aluminum strip to be cut is passed between the guide roller 43 and the pressure roller 41, which can guide the aluminum strip before the aluminum strip is height cut. The electric push rod 42 is mainly used to adjust the distance between the pressure roller 41 and the guide roller 43. There are two electric push rods 42, which are mainly adjusted synchronously by the control chip in the touch panel 2.

[0027] Please see Figures 1-2A touch panel 2 is also installed in the middle of the outer side wall of bracket 1. The touch panel 2 integrates control circuits and control chips.

[0028] As one implementation method, the touch panel 2 is mainly used to realize the coordinated operation of the high-speed cutting mechanism 5 and the guiding mechanism 4, and can also realize the automatic reset of the correction adjustment mechanism 6 and the correction clamping mechanism 7 after correction adjustment.

[0029] Please see Figures 1-4 The slide groove 61 is opened on the support platform 3, and the threaded rod 63 is installed in the slide groove 61. The threaded rod 63 passes through the slider 64 and is threadedly connected to the slider 64. The motor 62 is installed outside the support platform 3 and is directly opposite the threaded rod 63.

[0030] In one implementation, after the threaded rod 63 rotates under the action of the motor 62, it will cause the two sliders 64 to move synchronously along the slide groove 61 for adjustment under the action of threaded transmission.

[0031] Please see Figure 1 , Figure 3 , Figure 4 and Figure 5 The mounting plate 72 is welded to the slider 64. The mounting plate 72 has a T-shaped structure. The motor 3 71 is installed at the top center of the mounting plate 72. The bidirectional threaded rod 75 is connected to the power output end of the motor 3 71. The mating parts of the mounting plate 72, the clamping plate 74, and the bidirectional threaded rod 75 are all concave structures.

[0032] In one implementation, motor 71 is mainly used to provide power for the rotation of the bidirectional threaded rod 75. After the bidirectional threaded rod 75 rotates, the two clamping plates 74 will move closer to each other.

[0033] Please see Figure 1 , Figure 3 , Figure 4 and Figure 5 The clamping plate 74 is threadedly connected to the bidirectional threaded rod 75, and the clamping roller 73 is rotatably engaged with the clamping plate 74, with the upper and lower sides of the clamping roller 73 extending out of the clamping plate 74.

[0034] In one implementation, as the clamping plates 74 approach each other, they will clamp the two sides of the aluminum strip with the help of the clamping rollers 73. After the clamping rollers 73 clamp the aluminum strip, the aluminum strip can still be guided relative to the clamping plates 74. At this time, the clamping rollers 73 will rotate.

[0035] Please see Figure 1 , Figure 2 , Figure 4 and Figure 6The upright plate 86 is welded to the support platform 3. Each upright plate 86 has a sliding column 89 slidably installed on it in an up-down symmetrical manner. The end of the sliding column 89 facing away from the upright plate 86 is connected to a linkage plate 88. A spring 87 is also installed between the linkage plate 88 and the upright plate 86 on the outside of the sliding column 89.

[0036] As one implementation method, the sliding column 89 can ensure the stable sliding of the linkage plate 88 relative to the vertical plate 86, and the spring 87 is mainly used to realize the automatic reset of the linkage plate 88 after correction.

[0037] Please see Figure 1 , Figure 2 , Figure 4 and Figure 6 A telescopic rod 82 is installed on the upper side wall of the linkage plate 88 facing the vertical plate 86. The telescopic part of the telescopic rod 82 is connected to a pressure block 83. A correction clamping switch 84 is installed on the vertical plate 86 directly opposite the pressure block 83. A spring 81 is also installed between the pressure block 83 and the linkage plate 88. The telescopic rod 82 passes through the spring 81. A pressure block 810 is installed on the linkage plate 88 below the pressure block 83. A correction adjustment switch 85 is installed on the vertical plate 86 directly opposite the pressure block 810.

[0038] As one implementation method, when the aluminum strip deviates, it applies a lateral force to the linkage plate 88. After being subjected to the force applied by the aluminum strip, the linkage plate 88 moves towards the side closer to the vertical plate 86 under the action of the sliding column 89. As the linkage plate 88 approaches the vertical plate 86, the first pressure block 83 presses against the correction clamping switch 84, causing the correction clamping mechanism 7 to start first. As the linkage plate 88 moves further closer to the vertical plate 86, the telescopic rod 82 retracts. At this time, the first spring 81 is compressed. When the second pressure block 810 contacts the correction adjustment switch 85, the correction adjustment mechanism 6 is activated. By adopting the sequential activation method, the aluminum strip can be pre-clamped on both sides before correction to ensure subsequent synchronous correction on both sides.

[0039] The specific working principle is as follows: Before correcting the aluminum strip, the aluminum strip is first passed between two clamping plates 74 on the same side, and the linkage plate 88 is positioned on both sides of the aluminum strip. When the aluminum strip deviates before high-speed slitting, the aluminum strip will exert a lateral force on the linkage plate 88. After being subjected to the force by the aluminum strip, the linkage plate 88 will move towards the side closer to the vertical plate 86 under the action of the sliding column 89. As the linkage plate 88 approaches the vertical plate 86, the pressure block 83 will press against the correction clamping switch 84, so that the motor 71 in the correction clamping mechanism 7 will be started. After the motor 71 is started, the two clamping plates 74 will move closer to each other under the action of the bidirectional threaded rod 75. As the two clamping plates 74 move closer to each other, they will clamp the two sides of the aluminum strip with the help of the clamping roller 73, without affecting the normal conveying and slitting of the aluminum strip. As plate 88 moves closer to vertical plate 86, telescopic rod 82 retracts, compressing spring 81. When pressure block 810 contacts the correction adjustment switch 85, motor 62 in correction adjustment mechanism 6 is activated. Activation of motor 62 causes threaded rod 63 to rotate. The rotation of threaded rod 63, through threaded transmission, causes two sliders 64 to move synchronously in the same direction. Simultaneously, the movement of sliders 64, aided by the clamping mechanism, allows for synchronous correction of both sides of the aluminum strip. This correction method, which involves simultaneous clamping on both sides before correction, avoids the uneven force distribution on both sides of the aluminum strip caused by single-sided pushing correction. This reduces edge curling and twisting of the aluminum strip during correction, improving the correction quality during high-speed slitting.

[0040] The embodiments described in this specific implementation are 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.
