Description

Technical Field

[0001] This invention relates to the field of aluminum plate trimming technology, and in particular to an online trimming device. Background Technology

[0002] During the aluminum sheet production process, after the cold rolling process, defects such as burrs and cracks often exist on the edges of the aluminum sheet strip. To ensure the quality of the finished aluminum sheet, it is generally necessary to trim the edges of the aluminum sheet strip to make them smooth and flat.

[0003] Currently, most aluminum strip trimming devices are offline, meaning they are set up independently of the rolling line. The cold-rolled aluminum strip is transported to a separate trimming station for processing. These devices typically use abrasive media such as sandpaper to remove burrs from the edges of the aluminum strip. However, sandpaper gradually wears down over time, reducing its effectiveness. Replacing the sandpaper requires machine downtime, causing production line interruptions and impacting overall production efficiency. Summary of the Invention

[0004] In order to enable the replacement of the grinding position of flexible trimmed parts without stopping the machine, extend the downtime replacement cycle, and help ensure production efficiency, the present invention provides an online trimming device.

[0005] The online trimming device provided by this invention adopts the following technical solution: An online trimming device, comprising: A frame is used to be installed downstream of the cold rolling unit in a rolling line; Two bases are arranged opposite each other on the frame, with the two bases located on opposite sides of the product belt; Two columns are distributed opposite each other on the base, and the columns are movably mounted on the corresponding bases; A flexible trimming element, corresponding to the base, is wound around two columns of the corresponding base. The flexible trimming element is used to abut the edge of the product strip. A rotation drive mechanism is provided on the base, and the rotation drive mechanism is used to drive the two columns on the corresponding base to rotate synchronously and in the same direction. A vertical moving mechanism is installed on the base, and the vertical moving mechanism is used to adjust the two columns on the corresponding base to move up and down synchronously.

[0006] Preferably, the rotation drive mechanism includes: A drive motor is mounted on the corresponding base; The transmission cylinder corresponds to the column one by one. The column slides through the corresponding transmission cylinder in the vertical direction. Any transmission cylinder on the base is coaxially connected to the output shaft of the drive motor. A transmission assembly is disposed between the transmission cylinders, and the transmission assembly is used to drive the other transmission cylinder to rotate synchronously and in the same direction when one transmission cylinder rotates on the base.

[0007] Preferably, the vertical moving mechanism includes: A support frame is installed on the base; Adjusting nuts are rotatably mounted on the uprights. Each adjusting nut corresponds to a column. The outer wall of the column is provided with a threaded section, which is threadedly engaged with the corresponding adjusting nut. An adjustment component is provided on the upright, and the adjustment component is used to lock or unlock the adjusting nut relative to the upright.

[0008] Preferably, the adjustment component includes: A rotating ring is rotatably mounted on a corresponding upright, and the rotating ring is concentrically arranged with the center of the two uprights on the corresponding base, with the two uprights located inside the rotating ring. The gear ring is coaxially mounted on the swivel ring; A gear is coaxially mounted on the transmission cylinder, and the gear meshes with a gear ring. A limiting rod slides vertically through the adjusting nut. The limiting rod is located above the rotating ring. The rotating ring has a limiting groove for sliding cooperation with the limiting rod. The limiting groove is arc-shaped and concentric with the rotating ring. An adhesive component is provided on the adjusting nut. The adhesive component is used to bond and fix the limiting rod to the corresponding adjusting nut. When the limiting rod abuts against the surface of the rotating ring, the adhesive component bonds and fixes the limiting rod to the corresponding adjusting nut. An adsorption element is disposed within the defined groove. The adsorption element is used to adsorb the defined rod extending into the defined groove. The adsorption force of the adsorption element is greater than the adhesive force of the adhesive element. Tensioning rollers are provided on the columns, and flexible trimming parts are wound around the tensioning rollers corresponding to the two columns. The circumference of the flexible trimming parts is a first integer multiple of the circumference of the tensioning rollers, and the first integer is an even number. The number of teeth on the gear ring is a second integer multiple of the number of teeth on the gear, and the second integer is a third integer multiple of the first integer. The central angle of the limiting groove is 360° / (2×the third integer). The number of limiting grooves on the same circumference of the rotating ring is the third integer.

[0009] Preferably, the adhesive comprises: The first Velcro strap is attached to the adjusting nut; A second hook and loop fastener is provided on the limiting rod, and the first hook and loop fastener is used to bond and cooperate with the second hook and loop fastener.

[0010] Preferably, the adsorption element comprises: A first magnet is disposed on the bottom wall of the defined groove; The second magnet is disposed on the limiting rod. The first magnet is used to attract the second magnet and drive the limiting rod to move toward the direction closer to the rotating ring. The attraction force between the first magnet and the second magnet is greater than the adhesive force between the first hook and loop fastener and the second hook and loop fastener. The tail of the limiting groove along the rotation direction of the rotating ring is provided with a guide ramp. The guide ramp is used to slide against the limiting rod during the rotation of the rotating ring so that the limiting rod moves away from the limiting groove.

[0011] Preferably, the vertical moving mechanism includes: Each adjusting ring corresponds to one of the columns, and the columns are rotatably inserted into the corresponding adjusting rings. A vertical drive component is disposed on the base, and the vertical drive component is used to drive the adjusting ring to move in the vertical direction.

[0012] Preferably, the online trimming device further includes a base, the base being disposed on the base, the base being provided with a mounting seat, and a grinding wheel being rotatably disposed on the mounting seat for abutting against the edge of the product belt. In the product belt conveying direction, the grinding wheel is located upstream of the flexible trimming part, and the mounting seat is provided with a drive source for driving the grinding wheel to rotate.

[0013] Preferably, both the base and the mounting base are slidably disposed on the base platform, and the sliding direction of the base and the mounting base is perpendicular to the conveying direction of the product belt. A first moving drive component is disposed on the base platform, and the first moving drive component corresponds to the base and the mounting base respectively. The first moving drive component is used to drive the corresponding base or mounting base to slide.

[0014] Preferably, the base is slidably mounted on the frame, and the sliding direction of the base is perpendicular to the conveying direction of the product belt. The frame is provided with a second moving drive for driving the base to slide. Laser sensors are provided on opposite sides of the frame. The laser sensors are used to measure the distance from the laser sensor to the edge of the product belt. Both the laser sensors and the second moving drive are used to communicate with an external control system to adjust the position of the base according to the position of the edge of the product belt.

[0015] In summary, the present invention has the following beneficial technical effects: 1. During operation, the cold-rolled product strip passes through the trimming device. The flexible trimming parts on both sides of the base grind the edges of the product strip, which helps to remove burrs from the edges of the product strip. When the grinding effect of the flexible trimming parts decreases after a period of use, the two columns are driven to rotate synchronously in the same direction by the rotation drive mechanism. The two columns drive the flexible trimming parts to make the unused part on the side away from the product strip abut against the edge of the product strip, while the used and worn part moves to the side away from the product strip. This allows the trimming position on the flexible trimming parts to be updated without stopping the machine. 2. As the flexible trimming part continues to be used, when the grinding effect deteriorates again, the two columns are driven to rotate synchronously in the same direction by the rotation drive mechanism, and the two columns are simultaneously adjusted to rise or fall by the vertical movement mechanism. During the rotation and raising / lowering process, the columns not only change the contact position of the flexible trimming part with the product belt edge in the circumferential direction, but also change the contact position with the product belt edge in the vertical direction. During this process, the contact mark of the product belt edge on the flexible trimming part is spiral-shaped, avoiding the situation where the flexible trimming part and the product belt only move relative to each other in the vertical direction, which helps to ensure the trimming effect and refresh the usage position of the flexible trimming part. When the grinding effect deteriorates again, the above two processes are repeated in sequence, so that the grinding position of the flexible trimming part can be changed without stopping the machine, extending the overall cycle of downtime replacement and helping to ensure production efficiency.

[0023] The following combination Figures 1-6 The present invention will be described in further detail below.

[0024] Example 1:

[0025] This invention discloses an online trimming device. (Refer to...) Figure 1 , Figure 2 and Figure 3 The online trimming device includes a frame 1, a base 18, a base 2, a column 3, a flexible trimming component 4, a rotation drive mechanism 5, and a vertical moving mechanism. The frame 1 is fixed to the foundation downstream of the cold rolling unit of the rolling line by anchor bolts and is located upstream of the annealing equipment of the rolling line. It enables the product strip to be trimmed before annealing after cold rolling. In this embodiment, the product strip is an aluminum sheet strip. In other embodiments, the product strip can also be other metal sheets strips.

[0026] Reference Figure 1 and Figure 2 Furthermore, there are two bases 18, which are respectively set on opposite sides of the frame 1. Specifically, the two bases 18 are arranged along the width direction of the product belt, and the base 2 corresponds to the base 18 one by one. The base 2 is set on the corresponding base 18, so that the two bases 2 are respectively located on opposite sides of the product belt.

[0027] Reference Figure 2 and Figure 3The uprights 3 are movably mounted on the base 2. Two uprights 3 are distributed opposite each other on each base 2. The arrangement direction of the two uprights 3 is parallel to the product belt conveying direction. The upper end of each upright is coaxially fixed with a tension roller 25. The flexible trimming part 4 corresponds to the base 2 one by one. The flexible trimming part 4 is in the shape of an annular strip. The flexible trimming part 4 is wound between the tension rollers 25 of the two uprights 3 on the corresponding base 2. The two tension rollers 25 tension the annular flexible trimming part 4. The planar position of the flexible trimming part 4 is used to abut against the edge of the product belt to polish the burrs on the edge of the product belt.

[0028] Reference Figure 2 and Figure 3 Furthermore, a rotation drive mechanism 5 is installed on the base 2, which is used to drive the two columns 3 on the corresponding base 2 to rotate synchronously in the same direction; a vertical moving mechanism is installed on the base 2, which is used to adjust the two columns 3 on the corresponding base 2 to move up and down synchronously in the vertical direction.

[0029] During operation, the cold-rolled product strip passes through the trimming device. The flexible trimming parts 4 on both sides of the base 2 abut against the edges of the product strip, thus polishing the edges of the product strip and helping to remove burrs. When the polishing effect of the flexible trimming parts 4 decreases after a period of use, the two columns 3 are driven to rotate synchronously in the same direction by the rotation drive mechanism 5. The two columns 3 drive the flexible trimming parts 4 to move. With the transmission of the flexible trimming parts 4, the unused part on the side away from the product strip abuts against the surface of the product strip, while the used and worn part moves to the side away from the product strip. The transmission speed of the flexible trimming parts 4 is lower than the conveying speed of the product strip, and the transmission direction of the side of the flexible trimming parts 4 that abuts against the product strip is opposite to the conveying direction of the product strip. This allows the trimming position on the flexible trimming parts 4 to be updated without stopping the machine.

[0030] When the grinding effect decreases again as the flexible trimming part 4 continues to be used, the two columns 3 are driven to rotate synchronously and in the same direction by the rotation drive mechanism 5. The rotation direction is the same as the previous rotation. The two columns 3 are adjusted to rise or fall simultaneously by the vertical movement mechanism. Specifically, if the upper part of the flexible trimming part 4 is in contact with the edge of the product strip in the initial state, the column 3 is driven to rise; conversely, if the lower part of the flexible trimming part 4 is in contact with the edge of the product strip in the initial state, the column 3 is driven to fall. During the rotation and lifting process, the column 3 not only drives the flexible trimming part 4 to change the contact position in the circumferential direction, but also changes the contact position in the vertical direction. During this process, the contact mark of the edge of the product strip on the flexible trimming part 4 is spiral, which avoids the situation where the flexible trimming part 4 and the product strip only move relative to each other in the vertical direction. It is not easy to cause unstable force and damage to the edge of the aluminum strip, which helps to ensure the trimming effect, thereby completing the use position update of the flexible trimming part 4 again.

[0031] In subsequent use, when the flexible trimming part 4 needs to be updated on an odd-numbered basis, only the column 3 is driven to rotate. When the flexible trimming part 4 needs to be updated on an even-numbered basis, the column 3 is driven to rotate while simultaneously rising or falling. This allows for multiple changes to the trimming position of the flexible trimming part 4 without stopping the machine, extending the cycle of overall replacement during downtime and maximizing the use of the flexible trimming part 4, thus helping to ensure production efficiency. Furthermore, this invention places the trimming device downstream of the cold rolling unit, placing the trimming process within one stage of the rolling line. This allows for online trimming of the product strip without stopping the machine to transfer the product strip, helping to shorten the production cycle.

[0032] Reference Figure 2 To facilitate the grinding of the product's edges, the flexible trimming part 4 can be made of sandpaper, non-woven fabric, or abrasive cloth, etc., without any restrictions.

[0033] Reference Figure 3 and Figure 4 To facilitate the synchronous and unidirectional rotation of the two columns 3 on the corresponding base 2, the rotation drive mechanism 5 includes a drive motor 51, a transmission cylinder 52, and a transmission assembly 53. The drive motor 51 is embedded in the corresponding base 2 and can be a servo motor, stepper motor, or similar type. The transmission cylinder 52 is rotatably mounted on the base 2 in the vertical direction, and the transmission cylinder 52 corresponds one-to-one with the column 3. The column 3 slides through the corresponding transmission cylinder 52 in the vertical direction. Specifically, the transmission cylinder 52 has a vertical guide groove (not shown in the figure), and the outer wall of the column 3 is fixed with a guide rail (not shown in the figure) that slides with the vertical guide groove. This allows the column 3 to slide vertically relative to the corresponding transmission cylinder 52, but rotates synchronously with the corresponding transmission cylinder 52, thus providing the possibility for the column 3 to move up and down.

[0034] Reference Figure 3 and Figure 4Furthermore, in the two transmission cylinders 52 on the base 2, one transmission cylinder 52 is coaxially and fixedly connected to the output shaft of the drive motor 51. A transmission assembly 53 is disposed between the two transmission cylinders 52. The transmission assembly 53 is used to drive the other transmission cylinder 52 to rotate synchronously and in the same direction when one transmission cylinder 52 on the base 2 rotates. Specifically, in this embodiment of the invention, the transmission assembly 53 includes a transmission pulley 531 and a transmission belt 532. The transmission pulley 531 corresponds one-to-one with the transmission cylinder 52, and the transmission pulley 531 is fixedly sleeved on the corresponding transmission cylinder 52. The transmission belt 532 is wound between the two transmission pulleys 531, connecting the two transmission pulleys 531. In other embodiments, the transmission assembly 53 can also employ a combination of a transmission sprocket and a transmission chain, wherein the transmission sprocket corresponds one-to-one with the transmission cylinder 52, the transmission sprocket is fixedly sleeved on the corresponding transmission cylinder 52, and the transmission chain is wound around the two transmission sprockets to connect the two transmission sprockets.

[0035] When the grinding position of the flexible trimming part 4 needs to be changed, the drive motor 51 is started. The drive motor 51 drives the transmission cylinder 52 connected to it to rotate. Through the transmission pulley 531 and the transmission belt 532, the other transmission cylinder 52 is driven to rotate synchronously in the same direction. This helps the two transmission cylinders 52 to drive the two columns 3 to rotate synchronously in the same direction, so as to convey the flexible trimming part 4 and change the position of the contact part of the product belt on the flexible trimming part 4.

[0036] Reference Figure 3 and Figure 4 To facilitate the synchronous lifting and lowering of the two columns 3 on the corresponding base 2, the vertical moving mechanism includes a frame 6, an adjusting nut 7, and an adjusting assembly. The frame 6 is fixedly mounted on the corresponding base 2. The adjusting nut 7 rotates vertically through the frame 6 and is located above the transmission cylinder 52. The adjusting nut 7 corresponds one-to-one with the column 3. The outer wall of the column 3 is provided with a threaded section 8. The threaded section 8 of the column 3 is threaded through the corresponding adjusting nut 7 and threadedly engages with it. The threaded section 8 and the adjusting nut 7 are locked together, so that the column 3 will not slide vertically due to gravity when it is not rotating.

[0037] Reference Figure 3 and Figure 4The adjustment component is mounted on the support frame 6. The adjustment component is used to lock or unlock the adjustment nut 7 relative to the support frame 6. When the adjustment component locks the adjustment nut 7 relative to the support frame 6, the adjustment nut 7 cannot rotate relative to the support frame 6, making the adjustment nut 7 and the support frame 6 a whole. When the column 3 rotates, the adjustment nut 7 will move axially along the adjustment nut 7. When the adjustment component unlocks the adjustment nut 7 from the support frame 6, the adjustment nut 7 can rotate freely relative to the support frame 6. The rotational friction between the threaded section 8 on the column 3 and the adjustment nut 7 is greater than the rotational friction between the adjustment nut 7 and the support frame 6 after the adjustment nut 7 is unlocked. This causes the column 3 to rotate along with the corresponding adjustment nut 7 when the transmission cylinder 52 drives the column 3 to rotate.

[0038] Reference Figure 3 and Figure 4 To facilitate locking or unlocking the adjusting nut 7 relative to the support frame 6, the adjusting assembly includes a rotating ring 9, a gear ring 10, a gear 11, a limiting rod 12, an adhesive component 14, and an adsorption component 15. The rotating ring 9 is rotatably mounted on the support frame 6 of the corresponding base 2 via a bearing or a T-ring. The rotating ring 9 is concentrically arranged with the two columns 3 on the corresponding base 2. The rotating ring 9 is located between the base 2 and the adjusting nut 7, and the two transmission cylinders 52 are located inside the rotating ring 9. The gear ring 10 is coaxially fixedly mounted on the inner ring of the rotating ring 9. The gear 11 corresponds one-to-one with the transmission cylinder 52. The gear 11 is fixedly sleeved on the corresponding transmission cylinder 52. The gear 11 meshes with the gear ring 10, so that when the transmission cylinder 52 and the gear 11 rotate, they will drive the gear ring 10 and the rotating ring 9 to rotate.

[0039] Reference Figure 4 and Figure 5 The limiting rod 12 is cylindrical and corresponds one-to-one with the adjusting nut 7. The limiting rod 12 slides vertically through the bottom wall of the adjusting nut 7. When the trimming device is in its initial state, the limiting rods 12 on the two adjusting nuts 7 are symmetrically distributed around the center of the rotating ring 9 and located on the side of the two adjusting nuts 7 that is far apart from each other, so that the two limiting rods 12 are simultaneously aligned with the same circumference of the rotating ring 9.

[0040] Reference Figure 4 and Figure 5Specifically, the bottom wall of the adjusting nut 7 has a sliding cavity, and the limiting rod 12 slides through the sliding cavity. The groove of the sliding cavity has a constriction, the cross-sectional area of ​​which is smaller than the cross-sectional area of ​​the bottom of the sliding cavity. One end of the limiting rod 12 located in the sliding cavity has a convex ring 26 of elastic rubber. The size of the convex ring 26 is adapted to the cross-section of the sliding cavity, and the size of the limiting rod 12 is adapted to the cross-section of the constriction, so that the limiting rod 12 will not completely detach from the adjusting nut 7. The limiting rod 12 is located above the rotating ring 9, and the rotating ring 9 has a sliding engagement feature for sliding with the limiting rod 12. The limiting groove 13 is arc-shaped and concentrically arranged with the rotating ring 9. Each limiting groove 13 has a head and a tail. The head of the limiting groove 13 refers to the front end in the rotational direction when the transmission cylinder 52 drives the rotating ring 9 to rotate, and the tail refers to the rear end in the rotational direction when the transmission cylinder 52 drives the rotating ring 9 to rotate. The tail of the limiting groove 13 is provided with a guide ramp 27, which is used to slide and abut against the limiting rod 12 during the rotation of the rotating ring 9 so that the limiting rod 12 moves vertically away from the limiting groove 13. In this embodiment of the invention, there are two limiting grooves 13 on the rotating ring 9.

[0041] Reference Figure 4 and Figure 5 The adhesive component 14 is disposed in the sliding cavity of the adjusting nut 7. The adhesive component 14 is used to bond and fix the limiting rod 12 to the corresponding adjusting nut 7. When the limiting rod 12 abuts against the surface of the rotating ring 9, the adhesive component 14 bonds and fixes the limiting rod 12 to the corresponding adjusting nut 7. The adsorption component 15 is disposed in the limiting groove 13. The adsorption component 15 is used to adsorb the limiting rod 12 extending into the limiting groove 13. The adsorption force of the adsorption component 15 is greater than the adhesive force of the adhesive component 14.

[0042] Reference Figure 4 and Figure 5 Specifically, in order to enable the column 3 to move vertically at intervals during the intermittent rotation of the column 3, the circumference of the flexible trimming part 4 is a first integer multiple of the circumference of the tension roller 25, and the first integer is an even number. This allows the column 3 to rotate only half a turn of the first integer each time the grinding position of the flexible trimming part 4 is changed, thereby enabling the used side of the flexible trimming part 4 to be moved to the side away from the product belt.

[0043] Reference Figure 4 and Figure 5The number of teeth on the gear ring 10 is a second integer multiple of the number of teeth on the gear 11. This second integer multiple is a third integer multiple of the first integer. This ensures that each time the grinding position of the flexible trimming part 4 is changed, the column 3 rotates an integer number of times, and the rotating ring 9 rotates by a second integer fraction equal to the number of rotations of the column 3. Since the number of rotations of the column 3 is half of the first integer, it can be calculated that each time the grinding position of the flexible trimming part 4 is changed, the rotating ring 9 rotates by half of a third integer fraction. The number of limiting grooves 13 on the same circumference of the rotating ring 9 is a third integer. In the initial state, if the limiting rods 12 on the two adjusting nuts 7 are symmetrically distributed along the center of the rotating ring 9, then the second integer is at least twice the first integer.

[0044] Reference Figure 4 and Figure 5 Furthermore, the central angle of the limiting groove 13 is designed to be 360° / (2×third integer), that is, the ratio between the central angle of the limiting groove 13 and 360° is set to half of the third integer. When the trimming device is in the initial state, the limiting rod 12 on the adjusting nut 7 is aligned with the tail of the limiting groove 13 on the rotating ring 9, and when the column 3 rotates next time, the rotating ring 9 will make the tail of the limiting groove 13 move away from the limiting rod 12.

[0045] Reference Figure 4 and Figure 5In this embodiment of the invention, in the initial state, the limiting rods 12 on the two adjusting nuts 7 are symmetrically located on the side of the two adjusting nuts 7 that are far apart from each other. The limiting rods 12 on the two adjusting nuts 7 are respectively aligned and connected with the tails of the two limiting grooves 13. The circumference of the flexible trimming part 4 is four times the circumference of the tension roller 25 on the column 3. Every time the column 3 rotates two full revolutions, the flexible trimming part 4 can transmit half of the transmission, realizing the complete replacement of the grinding position. The number of teeth of the gear ring 10 is eight times the number of teeth of the gear 11. Every time the column 3 rotates two full revolutions, the gear ring 10 and the rotating ring 9 will rotate 90°. The central angle of the two limiting grooves 13 is 90°. The ratio between the central angle of the limiting groove 13 and 360° is one-quarter. There are two limiting grooves 13. Each time the flexible trimming part 4 needs to be replaced and its grinding position changed, the column 3 rotates two full revolutions. Specifically, when the flexible trimming part 4 needs to be replaced and its grinding position changed on an odd number of times, the drive mechanism 5 rotates the column 3, the gear 11 drives the gear ring 10 and the rotating ring 9 to rotate, and the rotating ring 9 drives the limiting groove 13 away from the limiting rod 12 aligned with the tail. At this time, the rotation of the column 3 will drive the adjusting nut 7 to rotate two revolutions in sync. The rotating ring 9 rotates 90°. After the replacement is completed, the limiting rod 12 on the adjusting nut 7 returns to its original position. At this time, the heads of the two limiting grooves 13 on the rotating ring 9 will be aligned with the limiting rods 12 on the two adjusting nuts 7 respectively. When the flexible trimming part 4 needs to be replaced and the grinding position needs to be changed on an even number of times, the rotating drive mechanism 5 drives the column 3 to rotate. The gear 11 drives the gear ring 10 and the rotating ring 9 to rotate. Since the head of the limiting groove 13 is aligned with the limiting rod 12, the limiting rod 12 will be inserted into the limiting groove 13 under the action of the adsorption part 15. As the rotating ring 9 rotates, the limiting rod 12 is located in the limiting groove 13 and slides relative to the limiting groove 13. Under the contact of the limiting rod 12 and the limiting groove 13, the adjusting nut 7 cannot rotate with the column 3. The thread of the threaded section 8 will actively cause the column 3 to rise or fall until the column 3 completes two rotations. The rotating ring 9 rotates 90° and returns to the initial state.

[0046] Reference Figure 4 To facilitate the bonding and fixing of the limiting rod 12 to the corresponding adjusting nut 7, the adhesive component 14 includes a first hook and loop fastener 141 and a second hook and loop fastener 142. The first hook and loop fastener 141 is fixedly mounted on the bottom wall of the sliding cavity of the adjusting nut 7, and is made of nylon with a rough, textured surface. The second hook and loop fastener 142 is fixedly mounted on the upper end face of the protruding ring 26 of the limiting rod 12, and is also made of nylon with a hook-like surface. The first and second hook and loop fasteners 141 and 142 can be bonded and fixed through the hook-and-loop engagement. When the lower end face of the limiting rod 12 abuts against the surface of the rotating ring 9, the first and second hook and loop fasteners 141 and 142 bond and engage, thus bonding and fixing the limiting rod 12 to the adjusting nut 7.

[0047] Reference Figure 4In other embodiments, the adhesive 14 can also be attached by magnetic adsorption. Specifically, magnet one is set on the bottom wall of the sliding cavity, and magnet two is set on the upper surface of the protruding ring 26 of the limiting rod 12. The relative fixation of the limiting rod 12 and the corresponding adjusting nut 7 can also be achieved by the adsorption of magnet one and magnet two.

[0048] Reference Figure 4 and Figure 5 To facilitate the insertion of the retaining rod 12 into the retaining groove 13, the adsorption component 15 includes a first magnet 151 and a second magnet 152. The first magnet 151 is fixed to the bottom wall of the retaining groove 13 and extends along the arc direction of the retaining groove 13. The second magnet 152 is fixed to the lower end face of the retaining rod 12. A magnetic attraction force is generated between the first magnet 151 and the second magnet 152. The first magnet 151 is used to attract the second magnet 152, thereby driving the retaining rod 12 to move towards the rotating ring 9 and extend into the retaining groove 13. The attraction force between the first magnet 151 and the second magnet 152 is greater than the adhesive force between the first hook and loop fastener 141 and the second hook and loop fastener 142, thereby ensuring that the retaining rod 12 can overcome the adhesive force of the hook and loop fastener under the action of magnetic force and be firmly held in the retaining groove 13. To facilitate the sliding contact between the retaining rod 12 and the guide ramp 27, the second magnet 152 is designed as a convex arc shape, and the cross-section of the first magnet 151 is a concave arc shape.

[0049] When the drive motor 51 is running, it drives the transmission cylinder 52 to rotate. The two transmission cylinders 52 drive the two columns 3 to rotate synchronously in the same direction. When the two columns 3 rotate for the first time to drive the flexible trimming part 4 to perform transmission replacement, the limiting rod 12 abuts against the surface of the rotating ring 9 and is close to the tail of the corresponding limiting groove 13. The first hook and loop fastener 141 and the second hook and loop fastener 142 are bonded. At this time, the rotation of the column 3 will drive the adjusting nut 7 to rotate. The gear 11 will drive the rotating ring 9 to rotate through the gear ring 10, so that the limiting groove 13 on the rotating ring 9 moves away from the aligned limiting rod 12. When the column 3 rotates for the first integer half turn, the flexible trimming part 4 completes the first replacement. At this time, the heads of the two limiting grooves 13 on the rotating ring 9 move to align with the limiting rods 12 on the two adjusting nuts 7. At this time, under the attraction of the first magnet 151, the limiting rod 12 extends into the limiting groove 13. The first magnet 151 and the second magnet 152 are attracted and engaged, and the first hook and loop fastener 141 and the second hook and loop fastener 142 are separated.

[0050] Next, the flexible trimming part 4 maintains its position and polishes the edge of the product. When it is necessary to drive the flexible trimming part 4 to change its position a second time, the drive motor 51 operates, and the two transmission cylinders 52 continue to drive the two columns 3 to rotate in the same direction as the first rotation. Since the limiting rod 12 is located in the limiting groove 13 at this time, the limiting rod 12 and the limiting groove 13 slide against each other during the rotation of the rotating ring 9, and the adjusting nut 7 cannot rotate. At this time, as the column 3 rotates, the column 3 will move axially along the adjusting nut 7, so that the position of the flexible trimming part 4 changes synchronously in the vertical direction until the column 3 rotates again for the first time. After half a revolution, the guide ramps 27 at the tails of the two limiting slots 13 on the rotating ring 9 abut against the limiting rod 12 and move out of the limiting slots 13. The flexible trimming part 4 completes its second replacement. The second replacement involves the coordination of lifting and transmission. At this time, the limiting rod 12 abuts against the surface of the rotating ring 9, and the tail of one of the limiting slots 13 is aligned. The first Velcro 141 and the second Velcro 142 are glued together, returning to the initial state. In subsequent replacements of the flexible trimming part 4, the column 3 only rotates during odd-numbered replacements; while during even-numbered replacements, the column 3 rotates and lifts. Through the coordination between the components in this invention, no complex control algorithm is required. The flexible trimming part 4 can be cyclically and repeatedly replaced simply by the drive motor 51 driving the transmission cylinder 52 to rotate a preset number of revolutions each time it is replaced.

[0051] Reference Figure 2 Each base 18 is equipped with a mounting seat 19, on which a grinding wheel 20 is rotatably mounted vertically. The grinding wheel 20 is used to abut against the edge of the product belt. The grinding wheel 20 and the flexible trimming component 4 are arranged sequentially along the conveying direction of the product belt, with the grinding wheel 20 located upstream of the flexible trimming component 4. A drive source (not shown in the figure) is provided on the mounting seat 19 to drive the grinding wheel 20 to rotate. Specifically, the drive source can be one of a stepper motor, servo motor, or drive motor embedded in the mounting seat 19, without limitation. The grinding wheel 20 is coaxially fixed with the output shaft of the drive source. The grinding wheel 20 can quickly remove large burrs and cracks on the edge of the product belt. After the edge of the product belt is coarsely ground by the grinding wheel 20, it continues to be conveyed forward. Then, the edge of the product belt reaches the trimming position of the flexible trimming component 4, which performs fine trimming on the edge of the product belt. The cooperation between the grinding wheel 20 and the flexible trimming component 4 in this invention helps to improve the trimming effect.

[0052] Reference Figure 2Both the base 2 and the mounting base 19 are slidably mounted on their respective bases 18. The sliding direction of both the base 2 and the mounting base 19 is perpendicular to the conveying direction of the product belt. A first moving drive component 22 is provided on the base 18, corresponding to both the base 2 and the mounting base 19. The first moving drive component 22 is used to drive the corresponding base 2 or mounting base 19 to slide. Specifically, two linear guide rails (not shown in the figure) are provided on the upper surface of the base 18 along a direction perpendicular to the conveying direction of the product belt. The linear guide rails correspond to the base 2 and the mounting base 19, respectively. A linear slider that cooperates with one of the linear guide rails is provided at the bottom of the base 2, and a linear slider that cooperates with the other linear guide rail is provided at the bottom of the mounting base 19.

[0053] Reference Figure 2 Specifically, the first moving drive component 22 can be a servo motor paired with a ball screw assembly. The ball screw assembly is rotatably mounted on the base 18 along the direction of the linear guide rail. The screw nut of the ball screw assembly is fixedly connected to the corresponding base 2 or mounting base 19 via a connecting plate. The servo motor is fixedly mounted on the base 18, and the output shaft of the servo motor is connected to the screw shaft of the corresponding ball screw assembly via a coupling. In other embodiments, the first moving drive component 22 can also be a cylinder, electric cylinder, etc., which can also drive the base 2 and mounting base 19 to move linearly.

[0054] The first moving drive component 22 drives the corresponding base 2 and mounting base 19 to slide in a direction perpendicular to the product belt conveyor, which helps to make the flexible trimming component 4 and the grinding wheel 20 simultaneously abut against the edge of the product belt as needed, or to make one of the flexible trimming component 4 or the grinding wheel 20 abut against the edge of the product belt.

[0055] Reference Figure 2 Furthermore, the base 18 is slidably mounted on the frame 1, and the sliding direction of the base 18 is perpendicular to the conveying direction of the product belt. The frame 1 is provided with a second moving drive 23, which corresponds one-to-one with the base 18. The second moving drive 23 is used to drive the corresponding base 18 to slide. In order to facilitate the guiding of the sliding of the base 18, the frame 1 is provided with a linear track, and the two bases 18 are slidably connected on the linear track.

[0056] Reference Figure 2 Specifically, the second moving drive component 23 can be a servo motor in conjunction with a ball screw, and the base 18 is connected to the corresponding ball screw nut. The second moving drive component 23 can also be a cylinder, an electric cylinder, etc., and the base 18 is fixed to the output end of the corresponding second moving drive component 23.

[0057] Reference Figure 2Each of the two sides of the frame 1 is fixed with a stand 29. Each stand 29 is equipped with a laser sensor 24. The laser sensor 24 is used to measure the distance from the laser sensor 24 to the edge of the product belt. Both the laser sensor 24 and the second moving drive 23 are connected to an external control system to adjust the position of the base 18 according to the position of the edge of the product belt.

[0058] During operation, two laser sensors 24 measure the distance from the two edges of the product belt to the laser sensors 24 in real time and transmit the data to the external control system. Based on the fixed distance between the two laser sensors 24, the external control system can calculate the actual width and center position of the product belt. The external control system compares the actual width of the product belt with the preset width. When the width of the product belt deviates from the preset width, the PLC controller calculates the distance and direction that the base 18 needs to move. The external control system drives the second moving drive 23 to work, causing the base 18 to slide so that the flexible trimming part 4 and the grinding wheel 20 can be moved to the working position.

[0059] Reference Figure 2 To facilitate the automation and intelligence of the device, the drive motor 51, drive source, and first moving drive component 22 are all connected to the external control system. Furthermore, an industrial camera is installed on the frame 1. The industrial camera is located downstream of the flexible trimming component 4 and is used to acquire image information of the product's edge. The industrial camera is connected to the external control system to send the image information of the product's edge to the external control system. The external control system analyzes the image information to determine the burr condition of the product's edge. If the burrs exceed the preset level, the external control system drives the drive motor 51 to work to replace the flexible trimming component 4.

[0060] The implementation principle of Embodiment 1 of the present invention is as follows: After the product strip is output from the cold rolling unit, it passes through the trimming device. The external control system controls the first moving drive component 22 to work according to the control command input by the user, so that the mounting base 19 and / or the base 2 moves to the working position. The distance from the two sides of the product strip to the laser sensor 24 is measured in real time by two laser sensors 24 and transmitted to the external control system. The external control system calculates the actual width and center position of the product strip. The external control system controls the second moving drive component 23 according to the edge position of the product strip, so that the second moving drive component 23 drives the base 18 to slide on the frame 1, adjusting the overall lateral position of the trimming device. The sliding of the base 18 causes the flexible trimming component 4 and / or the grinding wheel 20 to abut against the corresponding side edge of the product strip, thereby achieving the grinding of the edge of the product strip.

[0061] When the external control system determines that the burr removal in the product edge image information acquired by the industrial camera does not meet the preset level, the external control system controls the drive motor 51 to operate. The drive motor 51 drives the transmission cylinder 52 to rotate. The two transmission cylinders 52 drive the two columns 3 to rotate synchronously in the same direction. When the two columns 3 rotate for the first time to drive the flexible trimming part 4 to perform transmission replacement, the limiting rod 12 abuts against the surface of the rotating ring 9. At this time, the rotation of the column 3 will drive the adjusting nut 7 to rotate. The gear 11 will drive the rotating ring 9 to rotate through the gear ring 10, so that the limiting groove 13 on the rotating ring 9 moves away from the aligned limiting rod 12. When the column 3 rotates for the first integer half turn, the flexible trimming part 4 completes the first replacement. At this time, the heads of the two limiting grooves 13 on the rotating ring 9 move to align with the limiting rods 12 on the two adjusting nuts 7. At this time, under the attraction of the first magnet 151, the limiting rod 12 extends into the limiting groove 13.

[0062] Next, the flexible trimming part 4 remains in its position to polish the edge of the product strip. As the flexible trimming part 4 wears down, when the external control system determines that the burr removal in the product strip edge image information obtained by the industrial camera does not meet the preset level, it is necessary to drive the flexible trimming part 4 to change its position for the second time. Then, the external control system drives the drive motor 51 to run, and the two transmission cylinders 52 continue to drive the two columns 3 to rotate in the same direction as the first rotation. Since the limiting rod 12 is located in the limiting groove 13 at this time, the adjusting nut 7 cannot rotate during the rotation of the rotating ring 9. As the column 3 rotates, the column 3 will move axially along the adjusting nut 7, so that the position of the flexible trimming part 4 in the vertical direction changes synchronously. Until the column 3 rotates again by half a revolution of the first integer, the flexible trimming part 4 completes the second replacement. The second replacement is the coordination of lifting and transmission. At this time, the rotating ring 9, the limiting rod 12, and the adjusting nut 7 return to their initial state. During the subsequent replacement of the flexible trimming part 4, when the flexible trimming part 4 is replaced for the odd number of times, the column 3 only rotates; while when the flexible trimming part 4 is replaced for the even number of times, the column 3 will rotate and move up and down.

[0063] The trimming device in this invention enables multiple changes to the trimming position of the flexible trimmed part 4 without stopping the machine, extending the cycle of overall replacement during downtime and making full use of the flexible trimmed part 4, which helps to ensure production efficiency. Simultaneously, this invention places the trimming device downstream of the cold rolling unit, making the trimming process one link in the rolling line, performing trimming processing on the product strip online without stopping the machine to transfer the product strip, thus helping to shorten the production cycle.

[0064] Example 2:

[0065] Reference Figure 4 and Figure 6The difference between this embodiment and Embodiment 1 is that the vertical moving mechanism includes adjusting rings 16 and vertical driving components 17. Each adjusting ring 16 corresponds to a column 3, and the column 3 is rotatably mounted within the corresponding adjusting ring 16 via bearings. An adjusting plate 28 is fixedly connected to the outside of both adjusting rings 16. The vertical driving component 17 is fixedly mounted on the base 2 and is used to drive the two adjusting rings 16 to move synchronously in the vertical direction. Specifically, the vertical driving component 17 can be one of a cylinder, an electric cylinder, or an electric push rod; no limitation is made here. The vertical driving component 17 extends in the vertical direction, and the adjusting plate 28 is fixed to the output end of the vertical driving component 17. In this embodiment, two vertical driving components 17 are arranged opposite each other along the base 2, and the vertical driving component 17 is communicatively connected to an external control system.

[0066] The implementation principle of Embodiment 2 of the present invention is as follows: When it is necessary to change the vertical position of the flexible trimming part 4, during the rotation of the column 3, the vertical drive component 17 is activated. The vertical drive component 17 drives the adjusting plate 28 to move the two adjusting rings 16 up and down, so that the column 3 moves up and down in the vertical direction, realizing the synchronous rotation and vertical movement of the column 3. Since the column 3 can rotate freely within the adjusting rings 16, when the rotation drive mechanism 5 drives the column 3 to rotate, the column 3 rotates within the bearing of the adjusting rings 16, and the vertical movement mechanism does not affect the rotational movement of the column 3. The vertical movement mechanism of this embodiment has a simple structure and is easy to control. The height position of the flexible trimming part 4 can be precisely adjusted by controlling the stroke at the output end of the vertical drive component 17.

[0067] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
