[0001] This technical solution relates to the field of sheet metal processing equipment technology, specifically an automated sheet metal strip cutting machine. Background Technology

[0002] Wood panel cutting equipment is a type of machinery specifically designed to cut wood or wood-based panels (such as plywood, veneer, blockboard, etc.) into narrow strips along their length. Its core function is to transform large-format panels into uniformly wide strips of semi-finished products through directional cutting, which can then be used for further processing (such as furniture frames, flooring substrates, decorative moldings, etc.).

[0003] Chinese patent CN214815260U discloses a strip-cutting device for sheet metal. This device can only be used by manually feeding the sheet metal between the upper and lower rotating rollers, and then cutting it through the action of the upper and lower cutters. It is inseparable from manual operation and requires personnel to support the sheet metal at all times. In addition, it can only cut one sheet metal at a time, resulting in low processing efficiency and poor equipment functionality. Summary of the Invention

[0011] Preferably, the clamping assembly includes: a clamping mounting plate disposed on the movable mounting beam; a clamping lifting cylinder disposed on the clamping mounting plate; a clamping mounting seat disposed at the output end of the clamping lifting cylinder; a clamping movable plate hinged to the clamping mounting seat; a clamping cylinder disposed on one side of the clamping movable plate and having an output shaft; and a clamping plate disposed on the other side of the clamping movable plate for cooperating with the clamping mounting seat to clamp the plate; when the output shaft of the clamping cylinder extends, the clamping movable plate rotates, causing the clamping plate to move closer to the clamping mounting seat; when the output shaft of the clamping cylinder retracts, the clamping movable plate rotates under the gravity of the clamping cylinder, causing the clamping plate to move away from the clamping mounting seat.

[0012] Preferably, the clamping mounting base has a groove adapted to the output shaft, and the output shaft of the clamping cylinder abuts against the groove when it extends.

[0016] The key and beneficial technical effects of this technical solution compared to existing technologies are:

[0017] 1. The material conveying device designed in this technical solution can carry the sheet metal and transport the cut sheet metal to the unloading position, eliminating the need for personnel to manually support the sheet metal during processing and effectively preventing the sheet metal from being bumped or damaged. The area of ​​the sheet metal that the loading position on the conveying rack can hold is much larger than the area of ​​the sheet metal cut in one go. At the same time, the clamping mechanism can automatically push the remaining part of the sheet metal after one processing to the cutting position, realizing one loading and multiple processing, which greatly improves the efficiency of sheet metal cutting. The positioning mechanism can press the sheet metal, making it easier for the cutting device to process the sheet metal and ensuring the quality of sheet metal processing.

[0018] 2. The material conveyor designed in this technical solution has a simple structure, consisting of only a few crossbeams spliced ​​together. It can move on the main frame and the clamping mechanism can move on itself along the direction perpendicular to the cutting strip. The pushing component can limit the material to the loading position, so that the material can be processed in a stable state. Attached Figure Description

[0036] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.

[0037] like Figure 1-3 As shown, an automated sheet metal 9 cutting machine includes a main frame 1, a feeding device 12, and a cutting device 13. The main frame 1 includes front and rear ends, with a feeding position 21 at the front end and a feeding position 11 at the rear end. The cutting device 13 is located in the middle of the main frame 1. When the cutting machine is working, the operator first puts the sheet metal 9 into the feeding position 21 of the feeding device 12, and then the feeding device 12 carries the sheet metal 9 from the front end to the rear end of the main frame 1. During this process, the sheet metal 9 is cut into strips.

[0038] Specifically, the feeding device 12 includes a feeding frame 2, a driving mechanism, a positioning mechanism 5, and a clamping mechanism 6. The driving mechanism is mounted on the main frame 1 and is used to drive the feeding frame 2 to move along the cutting direction. The driving mechanism can be any mechanism that can drive the feeding frame 2 to move. In this embodiment, the driving mechanism is a sprocket mechanism. The feeding frame 2 is fixedly mounted on the sprocket chain. When the sprocket rotates, it can drive the feeding frame 2 to move. The positioning mechanism 5 is mounted on the feeding frame 2 and is used to press down the plate 9 so that the plate 9 is in contact with the cutting device 13 during the movement. The clamping mechanism 6 is mounted on the feeding frame 2 and can move along the direction perpendicular to the cutting direction. It can also be raised and lowered to clamp the uncut plate 9 so that the uncut plate 9 can be brought back by the feeding frame 2.

[0039] Furthermore, the feeding frame 2 is an approximately rectangular frame with a shearing position 22 in the feeding position 21. The feeding position 21 is the position where the board 9 is placed, and the shearing position 22 is the position in the feeding position 21 opposite to the cutting device 13. Whenever the feeding frame 2 moves once, the cutting device 13 cuts the board 9 in the shearing position 22 into strips, while the board 9 in the feeding position 21 excluding the shearing position 22 is not cut into strips. Therefore, after a large board 9 is placed in, the strip cutting machine can perform multiple automated strip cuttings. So, after the clamping mechanism 6 brings back the uncut board 9, it can also push the board 9 into the shearing position 22.

[0040] Furthermore, the strip cutting machine can be automated by using PLC programming. Before each strip cutting, the total width of the board 9 and the width of the strip to be cut can be input into the PLC interface. In this way, every time the board 9 is cut, the PLC will automatically calculate how wide the uncut board 9 is, and thus determine how much distance is needed to push the board 9 to the cutting position 22 each time, thereby realizing fully automated strip cutting.

[0041] like Figure 2 and Figure 3 As shown in this application, the direction along the cutting strip is defined as vertical, and the direction perpendicular to the cutting strip is defined as horizontal. The feeding rack 2 has two horizontally arranged feeding plates 23, which are the base frame of the feeding rack 2. The feeding plates 23 are arranged front and rear on the guide rail mechanism 3. Two vertical feeding beams 24 are arranged below the feeding plates 23. The two feeding plates 23 and the two feeding beams 24 form a rectangular frame. Several support plates 25 are arranged on the feeding beams 24. The space above the support plates 25 is the feeding position 21. Feeding connecting frames 26 are arranged above the two feeding plates 23. A second feeding beam 27 is arranged between the two feeding connecting frames 26. The positioning mechanism 5 is arranged on the second feeding beam 27. The space below the positioning mechanism 5 is the shearing position 22. A clamping mechanism 6 is also arranged on the feeding plates 23. When the driving device drives the feeding rack 2 to move through the feeding plates 23, the feeding device 12 and the plate 9 are all moved.

[0042] like Figure 3 and Figure 4 As shown, the clamping mechanism 6 includes a moving component 61 and a clamping component 62. The moving component 61 is arranged on the feeding plate 23 perpendicular to the cutting direction, and the moving mounting beam 617 of the moving component 61 can drive the clamping component 62 to move, so that the clamping component 62 can accurately clamp the plate 9. The clamping component 62 can be raised and lowered to clamp each uncut plate 9, so that it is brought back by the feeding frame 2, and then pushed to the cutting position 22 to wait for the next cutting.

[0043] Specifically, the moving assembly 61 includes two sets of lead screw assemblies and a movable mounting beam 617 disposed between the lead screw assemblies. Each lead screw assembly includes a moving motor 611, a moving guide rail 612, a moving slider 613, a movable mounting seat 614, and a moving lead screw 615. The moving motor 611 is disposed on the second conveying beam 27, the moving guide rail 612 is disposed on the conveying plate 23, the moving slider 613 is movably disposed on the moving guide rail 612, and the movable mounting seat 614 is disposed on the moving slider 613. One end of the moving lead screw 615 is connected to the output end of the moving motor 611, and the other end is radially fixed. A lead screw bushing 616 is also sleeved on the outside of the moving lead screw 615. When the moving motor 611 rotates, the moving slider 613 can be driven to move laterally through the action of the moving lead screw 615 and the lead screw bushing 616. The two ends of the movable mounting beam 617 are respectively connected to the two movable mounting seats 614, so the movable mounting beam 617 can also move laterally.

[0044] like Figure 2 and Figure 5 As shown, the clamping assembly 62 is mounted on the movable mounting beam 617. The number of clamping assemblies 62 can be determined according to actual working needs. The clamping assembly 62 includes a clamping mounting plate 621, a clamping lifting cylinder 622, a clamping mounting base 623, a clamping interactive plate, a clamping cylinder 625, and a clamping plate 627. The clamping mounting plate 621 is mounted on the movable mounting beam 617. The clamping lifting cylinder 622 is mounted on the clamping mounting plate 621 and is used to drive the clamping mounting base 623 to lift and lower to adjust the clamping position. The clamping mounting base 623 is located at the output end of the clamping lifting cylinder 622. The clamping movable plate 624 is hinged to the clamping mounting base 623. A holding cylinder 625 is located on one side of the clamping movable plate 624 and has an output shaft 626. A clamping plate 627 is located on the other side of the clamping movable plate 624 and is used to cooperate with the clamping mounting base 623 to clamp the plate 627. When the output shaft 626 of the clamping cylinder 625 extends, the clamping movable plate 624 can rotate around the hinge point, so that the clamping plate 627 moves closer to the clamping mounting base 623, thereby clamping the plate 627. When the output shaft 626 of the clamping cylinder 625 retracts, the clamping movable plate 624 is rotated around the hinge point under the gravity of the clamping cylinder 625, so that the clamping plate 627 moves away from the clamping mounting base 623, thereby releasing the plate 9.

[0045] Furthermore, the clamping mounting base 623 has a groove 628 adapted to the output shaft 626. When the output shaft 626 of the clamping cylinder 625 extends, it abuts against the groove 628. The groove 628 can guide the output shaft 626 and increase the stability of the clamping assembly 62.

[0046] like Figure 2 and Figure 6As shown, a pushing assembly 4 for limiting the sheet metal 9 within the loading position 21 is provided on the second conveying beam 27. The pushing assembly 4 includes a pushing seat 41, a pushing cylinder 42, a pushing guide rail 44, a pushing slider, and a pushing plate 43. The pushing seat 41 is located below the second conveying beam 27, the pushing cylinder 42 is located on the pushing seat 41, the pushing plate 43 is located at the output end of the pushing cylinder 42 and movably abuts against the sheet metal 9, the pushing guide rail 44 is located on the pushing seat 41, and the pushing plate 43 is movably located on the pushing guide rail 44 via the pushing slider. When the operator places the sheet metal 9 into the loading position 21, there is a gap between the sheet metal 9 and the inner edge of the conveying frame 2, so the pushing assembly 4 is needed to push it so that it is tightly attached to the conveying frame 2 to increase the stability during cutting.

[0047] like Figure 2 and Figure 7 As shown, the positioning mechanism 5 includes several positioning components 51 arranged along the conveying direction. Each positioning component 51 includes a positioning plate 52, a positioning cylinder 53, a positioning part 54, and a positioning guide part 55. The positioning plate 52 is mounted on the conveying beam 27, the positioning cylinder 53 is mounted on the positioning plate 52, the positioning part 54 is mounted on the output end of the positioning cylinder 53 and movably abuts against the plate 9, and the positioning guide part 55 is movably mounted on the positioning plate 52 and connected to the positioning part 54. The positioning cylinder 53 can drive the positioning part 54 to rise and fall to press the plate 9, so that the plate 9 is close to the cutting device 13, thereby improving the cutting effect of the plate 9.

[0048] like Figure 2 and Figure 8 As shown, the feeding rack 2 is equipped with a material-shifting assembly 7. Since the moving assembly 61 has a limited moving distance, when the remaining width of the sheet 9 is small, the material-shifting assembly 7 can move the sheet 9 to the shearing position 22. The material-shifting assembly 7 includes a material-shifting lifting cylinder 71, a material-shifting mounting base 72, a material-shifting moving cylinder 73, a material-shifting mounting plate 74, a material-shifting guide rod 76, and a material-shifting part 75. The material-shifting lifting cylinder 71 is mounted on the feeding beam 27 via the material-shifting mounting base 72. The material-shifting moving cylinder 73 is mounted on the output end of the material-shifting lifting cylinder 71 via the material-shifting mounting plate 74. The material-shifting part 75 is mounted on the output end of the material-shifting moving cylinder 73. The material-shifting mounting plate 74 is movably mounted on the material-shifting mounting base 72 via the material-shifting guide rod 76. The material-shifting guide rod 76 is used to increase the stability of the material-shifting mounting plate 74 when it is raised or lowered.

[0049] like Figure 2As shown, the guide rail mechanism 3 includes a first guide rail assembly 31 and a second guide rail assembly 32. The first guide rail assembly 31 works in conjunction with the second guide rail assembly 32 to move the material conveyor 2 along the cutting direction. The first guide rail assembly 31 is located in the middle of the main frame 1 and consists of two sets of rectangular guide rail assemblies. The rectangular guide rails have high precision and are suitable for the movement of the sheet material 9. The second guide rail assembly 32 is located on the side of the main frame 1 and consists of a set of circular guide rail assemblies. Since the clamping mechanism 6 is on the other side of the material conveyor 2 and has its own weight, the material conveyor 2 will tilt slightly towards the clamping mechanism 6. The first guide rail assembly 31 is closer to the clamping mechanism 6 and has a smaller impact. The second guide rail assembly 32 is located on the circular guide rail assembly, which can effectively alleviate the friction caused by the tilt, reduce the wear between the slider and the guide rail, and increase the service life of the guide rail.

[0050] like Figure 1 As shown, a dust collection device 8 is provided on the side of the cutting device 13 and the side of the unloading position 11. The dust collection device 8 can absorb debris from the surface of the board 9 at all times, thereby keeping the surface of the board 9 clean.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of this technical solution. Those skilled in the art should understand that this technical solution is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this technical solution. Various changes and modifications can be made to this technical solution without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed technical solution.
