Description

Technical Field

[0001] This invention relates to the field of aluminum plate production technology, and specifically to an automatic fixed-length slitting device for aluminum plates. Background Technology

[0002] Aluminum sheet refers to rectangular sheet material rolled from aluminum ingots. It is divided into pure aluminum sheet, alloy aluminum sheet, thin aluminum sheet, medium and thick aluminum sheet, and patterned aluminum sheet. Currently, aluminum sheet raw materials are mostly packaged in coils for convenient transportation and sales. In the processing of aluminum sheet, it is necessary to unwind the aluminum sheet coil and cut it to a fixed length.

[0003] Currently, aluminum raw materials tend to exhibit a certain degree of curvature during prolonged coiling and storage. This curvature can lead to poor flatness of the coil during slitting, resulting in slitting errors. Furthermore, the current coil quantitative slitting equipment on the market is technologically advanced, with high manufacturing and purchase costs, resulting in limited practicality. Additionally, burrs may appear at the cut edges of the coil during slitting, requiring secondary processing and impacting processing efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic fixed-length slitting device for aluminum plates in order to solve the above-mentioned problems, as detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This invention provides an automatic fixed-length slitting device for aluminum sheets, comprising a table, a digital display controller, a coil base, and an aluminum sheet coil.

[0010] Preferably, a tension spring is hung between the upper sides of the two linkage arms and the ends of the L-shaped support cranks to drive the linkage arms to rotate upward. The adjustment and positioning structure includes a slide rod one fixedly connected to the end of the adjustment block. The interior of each of the two L-shaped support cranks is provided with a slide rod hole that is slidably connected to the slide rod one. Fixed seats are fixedly connected to both sides of the upper surface of the table. A slide rod two is fixedly connected to the upper side of the fixed seat. A sliding sleeve fitted over the slide rod two is fixedly connected to the lower side of the adjustment block. The slide rod two is provided with a bolt fixing member for adjusting the position of the sliding sleeve. A distance sensor is fixedly installed in the middle of the surface of the clamping strip. The output end of the distance sensor is wirelessly connected to the input end of the digital display controller. The output end of the digital display controller is electrically connected to the motor one.

[0011] Preferably, the bolt fastener includes a bolt hole on the sliding sleeve, in which a bolt is threadedly connected, and the sliding rod 2 has several positioning holes for bolt insertion.

[0012] Preferably, the shearing structure includes two hydraulic cylinders fixedly installed on both sides of the bottom surface of the gantry frame. The movable ends of the two hydraulic cylinders are fixedly connected to the same oblique cutting blade. The surface of the table is provided with a cutting groove adapted to the oblique cutting blade. A grinding texture strip is fixedly connected to the lower side of both sides of the oblique cutting blade. A pressure plate is provided on the lower side of both sides of the oblique cutting blade to fix the roll material as it moves. The input end of the hydraulic cylinder is electrically connected to the output end of the digital display controller.

[0013] Preferably, two collars are fixedly connected to the upper ends of both sides of the oblique blade, and two uprights fitted with the collars are fixedly connected to the upper surface of the pressure plate. A spring is connected between the collar and the pressure plate, and the spring is fitted on the outside of the upright.

[0014] Preferably, the conveying structure includes a roller groove formed on the surface of the table. Both ends of the roller groove are fixedly connected to ear plates two. Two conveying rollers, one above the other, are rotatably connected between the two ear plates two and abut against each other. The abutment point of the two conveying rollers is flush with the upper surface of the table. A motor two for driving the conveying rollers to rotate is fixedly installed on one of the ear plates two. The input end of the motor two is electrically connected to the output end of the digital display controller.

[0015] Preferably, the unwinding drive includes a fixed triangular support plate and a movable triangular support plate. A circular plate is fixedly connected to the long side of both the fixed and movable triangular support plates. The circular plate at the fixed triangular support plate is rotatably connected to the upper end of one of the support plates.

A bearing is fixedly connected to the circular plate at the movable triangular support plate, and the other support plate is thickened, with its upper end being an arc surface that abuts against the outer wall of the bearing.

[0017] The beneficial effects are:

[0018] 1. By controlling the motor to drive the fixed roller shaft to rotate, the extrusion conveyor belt rotates accordingly, and the clamping bar contacts the surface of the roll material. At this time, the distance sensor is blocked. With the cooperation of the top support plate and the translational conveyor belt, the roll material is clamped. As the clamping bar continues to move to the adjusting roller shaft and then moves upward, the distance sensor and the surface of the roll material change. This sends an electrical signal to the digital display controller, which controls the hydraulic cylinder to drive the oblique cutter downward. With the cooperation of the cutter groove, the roll material is cut. With the continuous rotation of the clamping bar and the reciprocating up and down movement of the oblique cutter, automatic fixed-length cutting can be achieved. The structure is simple, the fixed-length cutting effect is good, and the manufacturing and purchase costs are reduced.

[0019] 2. By pulling the roll material from below, it is made to abut and pass over the guide roller shaft, and then pass between the clamping strip and the horizontal conveyor belt. While the roll material passes the guide roller shaft, the curved plate of the roll material is supported in the opposite direction, which can make the roll material laid on the table surface more flat, thereby avoiding cutting errors.

[0020] 3. As the beveled cutter continues to move downwards, under the elastic force of the compression spring, the two pressure plates can press down and fix the roll material on both sides of the beveled cutter, making the cutting more accurate and smooth. At the same time, it can ensure smooth grinding of the cut. When the clamping strip is not in contact with the surface of the roll material, the beveled cutter can rise partially. At this time, under the elastic force of the spring, the two pressure plates can still press down and fix the end of the roll material to prevent the roll material from inertially rewinding. This not only improves the fixing effect when cutting the roll material, but also grinds the burrs at the cut while cutting, thus improving work efficiency. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0032] See Figures 1-7As shown, this invention provides an automatic fixed-length slitting device for aluminum plates, including a table 1, a digital display controller 10, a coil base 14, and an aluminum plate coil 9. The device is characterized by: a hollow groove 2 penetrating the center of the upper surface of the table 1; a translation structure 3 for moving the coil on the surface of the table 1 below the hollow groove 2; the translation structure 3 includes translation rollers 302 rotatably connected to both sides of the hollow groove 2, and the two translation rollers 302 are connected by a translation conveyor belt 303; an extrusion drive structure 4 for intermittently conveying the coil on the surface of the translation structure 3 above the hollow groove 2; the extrusion drive structure 4 includes two L-shaped support cranks 401, and a fixed roller 402 and an adjusting roller 404 rotatably connected between the two L-shaped support cranks 401; the adjusting roller 404 can be horizontally adjusted along the extension direction of the table 1; and the fixed roller 402 and the adjusting roller 404... A tension roller 406 is rotatably connected above the 4, and the three are arranged in a triangle. The tension roller 406 elastically rises above the fixed roller 402 and the adjusting roller 404. The fixed roller 402, tension roller 406 and adjusting roller 404 are connected by a compression conveyor belt 407. A clamping strip 409 is fixedly connected to the surface of the compression conveyor belt 407 and abuts against the upper surface of the translation conveyor belt 303. The clamping strip 409 abuts against the translation conveyor belt 303 intermittently as the compression conveyor belt 407 rotates. A guide roller 12 is rotatably connected to the end of the table 1, and the roll material abuts against the upper side of the guide roller 12 and passes around it. A gantry frame 13 is fixedly connected to one side of the upper surface of the table 1. A shearing structure 7 for intermittently cutting the roll material is provided below the gantry frame 13. A conveying structure 8 for moving the cut aluminum plate is provided on the side of the table 1 away from the guide roller 12.

[0033] There are two coil bases 14, and support plates 15 are fixedly connected to the upper surfaces of both coil bases 14. Two support plates 16 are provided on the upper side between the two support plates 15, and an unwinding drive 6 is provided on the upper side wall of one of the support plates 15 to drive the two support plates 16 to rotate. It is worth mentioning that when the motor 3 601 drives the aluminum sheet coil 9 to unwind, it can rotate continuously and slowly, so that the unwinding coil slowly accumulates. First, the motor 1 410 drives the extrusion conveyor belt 407 and the clamping bar 409 to rotate. When the clamping bar 409 moves horizontally downward, it can drive the coil to move horizontally on the surface of the table 1 through the clamping cooperation with the horizontal conveyor belt 303. When the clamping bar 409 moves upward, the coil stops due to the lack of clamping force. At the same time, the distance sensor 11 detects the distance change and controls the digital display controller 10 to drive the hydraulic cylinder 701 to extend. The downward pressing process of the hydraulic cylinder 701 is a one-stage pressing. The lifting process of the pressure cylinder 701 is divided into two stages. During the downward pressing process, after a slight extension, the pressure plate 704 can abut and fix against the surface of the coil. As the hydraulic cylinder 701 fully extends, the oblique blade cutter 702 can cut the coil. During the lifting process, the oblique blade cutter 702 first rises above the cutter groove 703 (at this time, the pressure plate 704 continues to press down and fix the coil). At this time, the contact between the pressure plate 704 and the coil can avoid the coil's inertial retraction and avoid data deviation. After the distance sensor 11 rotates one revolution with the clamping bar 409 and contacts the surface of the coil again, the hydraulic cylinder 701 drives the oblique blade cutter 702 and the pressure plate 704 to lift in the second stage. At the same time, the two conveying rollers 803 rotate to transport the cut aluminum plate backward (the speed of the conveying rollers 803 is faster than the speed of the fixed rollers 402). Then, the new coil moves to the bottom of the oblique blade cutter 702 again. This process is repeated to complete the automatic fixed-length cutting.

[0034] Reference Figure 4 As shown, the translation structure 3 also includes four ear plates 301 fixedly connected to the bottom surface of the table 1, and the four ear plates 301 are respectively located at the four corners of the hollow groove 2. Both ends of the two translation roller shafts 302 are rotatably connected to the ear plates 301. The lower side of the hollow groove 2 is fixedly connected to the top support plate 304 through the connecting plate, and the top support plate 304 abuts against the upper inner wall of the translation conveyor belt 303. When the clamping strip 409 abuts against the surface of the roll material, it squeezes the translation conveyor belt 303. Under the support of the top support plate 304, the translation conveyor belt 303 can achieve clamping cooperation with the clamping strip 409 and can smoothly drive the roll material to move. At this time, the translation conveyor belt 303 can rotate with it.

[0035] As an optional implementation, the extrusion drive structure 4 further includes two adjusting blocks 403 and two linkage arms 405. The fixed roller shaft 402 is rotatably connected to one side between two L-shaped support cranks 401, and a motor 410 for driving the fixed roller shaft 402 to rotate is fixedly installed on the outer wall of one of the L-shaped support cranks 401. The lower ends of the two linkage arms 405 are respectively rotatably connected to the two ends of the shaft of the fixed roller shaft 402. The tension roller shaft 406 is rotatably connected between the upper ends of the two linkage arms 405, and the adjusting roller shaft 404 is rotatably connected between the two adjusting blocks 403. The table 1 has adjustment and positioning structures 5 on both sides of its surface for fixing the position of the adjustment block 403. The roll material passes between the clamping bar 409 and the translation conveyor belt 303. When the motor 410 rotates, it can drive the extrusion conveyor belt 407 to rotate continuously. When the clamping bar 409 rotates to the bottom and moves horizontally, it can drive the roll material to move by cooperating with the translation conveyor belt 303. When the clamping bar 409 moves to the adjustment roller shaft 404 and rises, the distance between the distance sensor 11 on its surface and the surface of the roll material changes and sends an electrical signal to the digital display controller 10.

[0036] Reference Figure 5As shown, a tension spring 408 is hung between the upper side of the two linkage arms 405 and the end of the L-shaped support crank 401 to drive the linkage arms 405 to rotate upward. The adjustment and positioning structure 5 includes a slide rod 501 fixedly connected to the end of the adjustment block 403. The interior of each of the two L-shaped support cranks 401 is provided with a slide rod hole 502 that slides and connects to the slide rod 501. Fixed seats 503 are fixedly connected to both sides of the upper surface of the table 1. A slide rod 504 is fixedly connected to the upper side of the fixed seat 503. A sliding sleeve 505 is fixedly connected to the lower side of the adjustment block 403 and is sleeved on the slide rod 504. A bolt fixing part is provided on the slide rod 504 to adjust the position of the sliding sleeve 505. A distance sensor 11 is fixedly installed in the middle of the surface of the clamping bar 409. The output end of the distance sensor 11 is wirelessly connected to the input end of the digital display controller 10 (this wireless connection method is prior art and well known to those skilled in the art). (This will not be elaborated further). The output terminal of the digital display controller 10 is electrically connected to the motor 410. The bolt fastener includes a bolt hole 506 on the sliding sleeve 505, and a bolt 507 is threaded into the bolt hole 506. The sliding rod 504 has several positioning holes 508 that are inserted into the bolt 507. When it is necessary to adjust the length of the aluminum plate cut each time, the two adjusting blocks 403 are moved at the same time, so that the sliding rod 501 slides in the sliding rod hole 502, and the sliding sleeve 505 slides on the sliding rod 504. (During the movement, the extrusion conveyor belt 407 drives the tension roller shaft 406 to move downward. At this time, the linkage arm 405 rotates downward and drives the tension spring 408 to stretch elastically.) After the sliding sleeve 505 moves to the appropriate position, the bolt 507 is inserted into the bolt hole 506 and rotated until it is inserted into the positioning hole 508, thus completing the position fixation of the sliding sleeve 505. The distance sensor 11 can detect whether the clamping strip 409 is in contact with the surface of the roll material.

[0037] Reference Figure 3As shown, the shearing structure 7 includes two hydraulic cylinders 701 fixedly installed on both sides of the bottom surface of the gantry frame 13. The movable ends of the two hydraulic cylinders 701 are fixedly connected to the same oblique cutting blade 702. The surface of the table plate 1 is provided with a cutting groove 703 adapted to the shearing of the oblique cutting blade 702. A grinding texture strip 708 is fixedly connected to the lower side of both sides of the oblique cutting blade 702. Pressure plates 704 are provided on the lower side of both sides of the oblique cutting blade 702 to fix the roll material as it moves. The hydraulic cylinders 701 The input terminal is electrically connected to the output terminal of the digital display controller 10. Two collars 705 are fixedly connected to the upper ends of both sides of the oblique blade cutter 702. Two uprights 706, fitted onto the collars 705, are fixedly connected to the upper surface of the pressure plate 704. A spring 707 connects the collars 705 and the pressure plate 704, and the spring 707 is fitted onto the outside of the uprights 706. When the control hydraulic cylinder 701 extends, its output terminal drives the oblique blade cutter 702 to move downwards. Because its cutting edge is oblique, it... After contacting the edge of the cutting groove 703, the sheet material can be cut smoothly. As the oblique cutting blade 702 moves down and up, the two grinding grooves 708 on its surface can grind the cut area of ​​the sheet material. When the oblique cutting blade 702 moves down a small distance, the two pressure plates 704 come into contact with the surface of the roll material. As the oblique cutting blade 702 continues to move down, under the elastic force of the compression spring 707, the two pressure plates 704 can press down and fix the roll material on both sides of the oblique cutting blade 702, so that the sheet material is cut smoothly. The cutting is more accurate and smooth, and the cutting edge can be smoothly polished. When the clamping bar 409 is not in contact with the surface of the roll material, the oblique blade cutter 702 can rise incompletely. At this time, the two pressure plates 704 can still press down and fix the end of the roll material under the elastic force of the spring 707 to prevent the roll material from rolling back due to inertia. After the clamping bar 409 rotates one revolution and contacts the roll material again, the oblique blade cutter 702 and the two pressure plates 704 will rise completely again (at this time the roll material can move smoothly).

[0038] Reference Figure 3 As shown, the conveying structure 8 includes a roller groove 801 formed on the surface of the table 1. Both ends of the roller groove 801 are fixedly connected to ear plates 802. Two conveying rollers 803, one above the other, are rotatably connected between the two ear plates 802 and abut against each other. The abutment of the two conveying rollers 803 is flush with the upper surface of the table 1. A motor 804 for driving the conveying roller 803 to rotate is fixedly installed on one of the ear plates 802. The input end of the motor 804 is electrically connected to the output end of the digital display controller 10. By controlling the rotation of the motor 804, the two conveying rollers 803 can be driven to rotate. The aluminum plate between the two conveying rollers 803 can be smoothly conveyed to the subsequent process. At the same time, because the two conveying rollers 803 are tightly abutting against each other, the edge bends of the aluminum plate (caused by shearing or other reasons) can be rolled flattened.

[0039] Reference Figure 6 As shown, the unwinding drive component 6 includes a fixed triangular support plate 603 and a movable triangular support plate 609. A circular plate 602 is fixedly connected to the long side of both the fixed and movable triangular support plates 603 and 609. The circular plate 602 at the fixed triangular support plate 603 is rotatably connected to the upper end of one of the support plates 15. A motor 601 for driving the circular plate 602 at this location is fixedly installed on the upper side wall of the support plate 15. Both ends of the opposing surfaces of the two support plates 16 have wedge-shaped fitting grooves that engage with the fixed and movable triangular support plates 603 and 609. 605. The input terminal of motor 601 is electrically connected to the output terminal of digital display controller 10. Motor 601 can drive the fixed triangular support plate 603 and aluminum plate coil 9 to unwind and rotate. The fixed triangular support plate 603 and the movable triangular support plate 609 can drive the top support fixing plate 16 and aluminum plate coil 9 to rotate by engaging with the fitting groove 605. The design of the two top support fixing plates 16 can stably fix the aluminum plate coil 9 while facilitating the removal of the lifting straps of the aluminum plate coil 9.

[0040] Furthermore, a threaded rod 604 is fixedly connected to the fixed triangular support plate 603. A through hole 608, which is fitted onto the threaded rod 604, is provided in the middle of both the movable triangular support plate 609 and the circular plate 602. A nut 607, used to press the movable triangular support plate 609 towards the fixed triangular support plate 603, is threaded to the end of the threaded rod 604. A bearing 606 is fixedly connected to the circular plate 602 at the movable triangular support plate 609. Another support plate 15 is thickened, and its upper end is an arc surface that abuts against the outer wall of the bearing 606. When the two support fixing plates 16, together with the aluminum sheet coil 9, are fitted onto the outside of the threaded rod 604, the two fitting grooves 605 at one end of the two support fixing plates 16 abut against the two sides of the fixed triangular support plate 603. Then, the movable triangular support plate 609 is fitted onto the end of the threaded rod 604 through the through hole 608. The inclined surfaces on both sides of the movable triangular support plate 609 abut against the two fitting grooves 605 at the other end of the two support fixing plates 16. Then, the nut 607 is rotated at the end of the threaded rod 604. As the nut 607 continues to move, the movable triangular support plate 609 can be squeezed to move towards the fixed triangular support plate 603. As the two approach each other, under the wedge fit, the two support fixing plates 16 move in opposite directions to support and fix the middle hole of the aluminum sheet coil 9. At the same time, the end plates at both ends of the two support fixing plates 16 can limit the ends of the coil to prevent the coil from shifting during rotation. The bearing 606 can make the other end of the threaded rod 604 rotate more stably by supporting the bearing 606 through the support plate 15. The support plate 15 is installed after the aluminum sheet coil 9 is fixed.

[0041] Working principle of the invention:

[0042] First, insert the two support fixing plates 16 into the middle hole of the aluminum sheet coil 9. Then, put the aluminum sheet coil 9 and the two support fixing plates 16 together onto the threaded rod 604. At this time, the driving triangular support plate 609 is moved towards the fixed triangular support plate 603, and the two support fixing plates 16 are moved outward in the middle hole of the coil to fix the aluminum sheet coil 9. Then, pull the coil from below so that it abuts and passes over the guide roller shaft 12 from above, and passes in sequence between the clamping strip 409 and the translational conveyor belt 303; between the two pressure plates 704 and the table 1; and between the two conveyor roller shafts 803.

[0043] Subsequently, the digital display controller 10 controls the motor 601 to drive the aluminum sheet coil 9 to unwind. At this time, the coil is appropriately piled and bent on the front side of the table 1 (e.g., ...). Figure 1 As shown in the diagram, the control motor 410 drives the fixed roller shaft 402 to rotate. At this time, the extrusion conveyor belt 407 rotates with it, and the clamping bar 409 contacts the surface of the roll material. At this time, the distance sensor 11 is blocked. With the cooperation of the support plate 304 and the translation conveyor belt 303, the purpose of clamping the roll material is achieved. As the clamping bar 409 continues to move to the adjusting roller shaft 404 and then moves upward, the distance sensor 11 and the surface of the roll material will change. An electrical signal is sent to the digital display controller 10, which controls the hydraulic cylinder 701 to drive the oblique blade cutter 702 to move downward. With the cooperation of the cutter groove 703, the roll material is cut. Then, the two conveying roller shafts 803 are controlled to rotate to convey the cut aluminum plate backward.

[0044] After the clamping bar 409 rotates once, it comes into contact with the surface of the roll material again, and drives the roll material to be conveyed a fixed distance below the oblique blade cutter 702. This process is repeated to achieve automatic fixed-length cutting.

[0045] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
