Description

Technical Field

[0001] This invention relates to the field of pipe cutting technology, and in particular to a cutting device for processing spiral perforated mesh filter cylinders. Background Technology

[0002] Laser cutting utilizes a focused, high-power-density laser beam to irradiate a workpiece, causing the irradiated material to rapidly melt, vaporize, or reach its ignition point. Simultaneously, a high-speed airflow coaxial with the laser beam blows away the molten material, thereby cutting the workpiece. It is one of the thermal cutting methods for cutting workpieces. Spiral perforated mesh filter cartridges are filtration devices made from metal sheets through punching and cutting processes. Their surfaces are spiral-shaped and contain a large number of mesh holes.

[0003] When using laser cutting to process spiral perforated mesh filter cylinders, slag and nodules are easily generated on the cut workpiece. These slag and nodules remain at both ends of the workpiece and are difficult to clean. Summary of the Invention

[0018] Beneficial effects

[0019] 1. The present invention has an end cleaning mechanism for mechanically removing slag and nodules from both ends of the cut spiral perforated mesh filter cylinder. Two arc-shaped clamps fit against the inner sides of the spiral perforated mesh filter cylinder, clamping the cut spiral perforated mesh filter cylinder from the inside. At the same time, the angle rotation of the first brush and the second brush is used to scrape off the slag and nodules from the inner and outer walls of the cut part of the spiral perforated mesh filter cylinder.

[0020] 2. When encountering slag and nodules in the recessed areas of the cut mesh, rotational sweeping may not be able to remove the slag and nodules effectively. Removal can be achieved by moving the first and second brushes laterally. Repeatedly move the two ends of the spiral perforated screen filter cylinder laterally, that is, make short reciprocating movements along the connecting rod. During the lateral movement of the first and second brushes, the bristles can move to the cut mesh area and sweep it laterally.

[0021] 3. In cases where the complete circular hole near the cut is blocked, the present invention completely retracts the first brush 619 and the second brush into the spiral perforated screen filter cylinder, keeps the first brush horizontal or slightly open, and then rotates the second brush back and forth. The ceramic bristles on the second brush will push the slag and nodules in the complete circular hole outward, thereby removing the slag and nodules on the spiral perforated screen filter cylinder.

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] like Figure 1As shown in the figure, an embodiment of the present invention provides a cutting device for processing a spiral perforated mesh filter cartridge, including a first worktable 100 and a second worktable 200, which are fixedly connected. An end cleaning mechanism 600 is rotatably provided on the first worktable 100, and a driving mechanism 300 is installed on the second worktable 200. The driving mechanism 300 is used for fixing and moving the spiral perforated mesh filter cartridge 400. A laser cutting mechanism 500 is also rotatably provided on the side of the first worktable 100. When the laser cutting mechanism 500 cuts the spiral perforated mesh filter cartridge 400, the driving mechanism 300 can fix the spiral perforated mesh filter cartridge 400 and rotate it. After one end is cut, the driving mechanism 300 can also push the spiral perforated mesh filter cartridge 400 forward as a whole, which facilitates the segmented cutting of the spiral perforated mesh filter cartridge 400.

[0032] like Figure 2 and Figure 3 As shown, the drive mechanism 300 includes two first mounting brackets 301, both of which are fixedly mounted on the table surface of the second workbench 200. The two first mounting brackets 301 are symmetrically arranged. Each of the two first mounting brackets 301 has a first roller 302 rotatably mounted inside it. Both first rollers 302 are driven by a motor, and the distance between the two first rollers 302 is adjustable. Specifically, one of the first mounting brackets 301 has a sliding groove, and a cylinder is fixedly mounted inside the sliding groove. The output end of the cylinder is fixedly connected to the motor that drives the first roller 302 to rotate. The motor slides in the sliding groove. When it is necessary to adjust the distance between the two first rollers 302, the cylinder drives the motor to slide a certain distance in the sliding groove, thereby achieving the adjustment of the distance between the two first rollers 302.

[0033] like Figure 2 As shown, each of the two first mounting brackets 301 is fixedly equipped with a second mounting bracket 306. A T-shaped plate 309 is fixedly mounted on each second mounting bracket 306. One second mounting bracket 306 has a threaded rod 307 rotatably mounted on it and a second limiting rod 308 fixedly mounted on it. The other second mounting bracket 306 has two second limiting rods 308 fixedly mounted on it. The T-shaped plate 309 and the threaded rod 307 are threadedly engaged, and the T-shaped plate 309 and the second limiting rods 308 are slidably engaged. Figure 3As shown, a first limiting groove 312 is fixedly provided at the bottom of the T-shaped plate 309, a first motor 313 is connected to the bottom of the threaded rod 307, and a pad 311 is provided at the connection between the second limiting rod 308 and the threaded rod 307 and the second worktable 200. The second limiting rod 308 is fixedly connected to the pad 311, and the threaded rod 307 is rotatably connected to the pad 311. The first motor 313 is located at the bottom of the second worktable 200 and is fixedly connected to the second worktable 200. A second limiting groove 310 is also fixedly provided on the second worktable 200 at a position corresponding to the first limiting groove 312. When the spiral perforated mesh filter cylinder 400 is located in the second limiting groove 310, the first limiting groove 312 moves downward and the second limiting groove 310 cooperate to limit the spiral perforated mesh filter cylinder 400.

[0034] like Figure 2As shown, two third mounting brackets 305 are fixedly provided on the end of the second worktable 200 near the two first rollers 302. The two third mounting brackets 305 correspond to the positions of the two first mounting brackets 301. A second roller 303 is rotatably mounted on each of the two third mounting brackets 305. Both second rollers 303 are driven by a second motor 304. The two first rollers 302 are horizontally set, and the two second rollers 303 are vertically set. During use, the drive mechanism 300 needs to move the spiral perforated mesh filter cylinder 400 forward and rotate it to facilitate cutting. Therefore, this embodiment uses two first rollers 302 to move the spiral perforated mesh filter cylinder 400 forward. Specifically, when one end of the spiral perforated mesh filter cylinder 400 is finished cutting and needs to be pushed forward, the distance between the two first rollers 302 is adjusted so that the first rollers 302 contact the side of the spiral perforated mesh filter cylinder 400. At this time, the drive motor causes the first rollers 302 to rotate. It should be noted that the two first rollers 302 rotate in opposite directions to facilitate the forward movement of the spiral perforated mesh filter cylinder 400. When the spiral perforated mesh filter cylinder 400 reaches the designated position and needs to be rotated and cut with the laser cutting mechanism 500, the distance between the two first rollers 302 is increased, and the two second rollers 303 are controlled to rotate. The two second rollers 303 contact the spiral perforated mesh filter cylinder. The 400 contact enables the rotation of the spiral perforated mesh filter cylinder 400, allowing the laser cutting mechanism 500 to perform spiral cutting on the spiral perforated mesh filter cylinder 400. During its movement, the spiral perforated mesh filter cylinder 400 is limited between the first limiting groove 312 and the second limiting groove 310. Since no limiting mechanism is provided at both ends of the spiral perforated mesh filter cylinder 400 in this embodiment, the spiral perforated mesh filter cylinder 400 may not rotate in place during the rotation process, but may move forward a certain distance. Therefore, this embodiment also includes a limiting mechanism to limit the rotation of the spiral perforated mesh filter cylinder 400, including but not limited to a baffle provided at the cutting end of the spiral perforated mesh filter cylinder 400. The baffle can limit the spiral perforated mesh filter cylinder 400 by hand or other means. It also includes a clamping plate that can rotate synchronously at the end of the spiral perforated mesh filter cylinder 400. The clamping plate can only rotate to prevent the spiral perforated mesh filter cylinder 400 from undergoing lateral displacement.

[0035] The distance between the two second rollers 303 in this embodiment can also be adjusted. The specific adjustment method can refer to the adjustment method between the two first rollers 302. This embodiment only provides one adjustment method, but other methods can be used for adjustment when implementing this technical solution.

[0036] like Figure 3As shown, the laser cutting mechanism 500 includes a first rotating arm 501, which is rotatably mounted at one end of the second worktable 200. A third motor 502 is provided at the rotatable connection between the first rotating arm 501 and the second worktable 200. The third motor 502 is fixedly mounted on the second worktable 200. A second rotating arm 503 is rotatably mounted at one end of the first rotating arm 501. The rotatable connection is driven by a motor. A cutting head 504 is mounted on the second rotating arm 503. A connecting line 505 is provided on the cutting head 504. The other end of the connecting line 505 is fixedly connected to a control box 506. The control box 506 is fixedly connected to the first rotating arm 501. In use, the first rotating arm 501 is rotated by the third motor 502, and then the second rotating arm 503 is rotated to move the position of the cutting head 504. The cutting head 504 moves to the cutting position, and then the spiral perforated mesh filter cylinder 400 rotates to achieve segmented cutting of the spiral perforated mesh filter cylinder 400.

[0037] The Laser Cutting Mechanism 500 is a precision manufacturing device that uses a high-energy laser beam to cut materials and is widely used in actual production.

[0038] After the laser cutting mechanism 500 cuts, slag and nodules are easily generated at the cut points of the spiral perforated mesh filter cylinder 400, requiring chemical etching or manual cleaning. The chemical immersion solution is corrosive and will produce toxic gases after volatilization, while manual cleaning is inefficient. Therefore, this embodiment provides a mechanical removal method for slag and nodules to remove the slag and nodules generated at the cut points at both the inner and outer ends of the spiral perforated mesh filter cylinder 400.

[0039] like Figure 4 As shown, the end cleaning mechanism 600 includes a rotary disk 601. A back plate 602 is fixedly mounted on the first worktable 100, and the back plate 602 is rotatably connected to the rotary disk 601. A plurality of first telescopic cylinders 603 are fixedly mounted on the rotary disk 601. A gasket 604 is fixedly mounted on the rotary disk 601 at the output end of the first telescopic cylinder 603. The output end of the first telescopic cylinder 603 passes through the gasket 604 and is fixedly mounted with a first connecting member 605. A slag removal component is detachably connected to the first connecting member 605. The detachable connection between the slag removal component and the first connecting member 605 can be achieved by means of threaded connection, magnetic attraction, snap-fit, etc. In use, a slag removal component can be connected to any of the first connecting members 605, and the slag removal component is moved to the position of the cut spiral perforated screen filter cartridge 400 by the rotation of the rotary disk 601.

[0040] like Figure 4 As shown, the slag removal assembly includes a second connector 606, which is detachably connected to the first connector 605. A connecting rod 607 is coaxially and fixedly mounted on the second connector 606, as shown in the figure. Figure 5As shown, a rectangular shell 608 is fixedly mounted on the connecting rod 607. Arc-shaped clamping plates 610 are slidably mounted on both the upper and lower ends of the rectangular shell 608. A bidirectional telescopic cylinder 609 is fixedly mounted on one end of the rectangular shell 608. Side plates 611 are fixedly mounted on both sides of the two arc-shaped clamping plates 610. The output ends on both sides of the bidirectional telescopic cylinder 609 are fixedly connected to the side plates 611 on the same side of the two arc-shaped clamping plates 610, respectively. A first telescopic rod (not marked in the figure) is fixedly mounted on both sides of one end of the rectangular shell 608. The extension of the two first telescopic rods is fixedly connected to the side plates 611 on the other side of the arc-shaped clamping plates 610 at the upper and lower ends, respectively. When the bidirectional telescopic cylinder 609 is working, the position of the two arc-shaped clamping plates 610 is changed, which facilitates the clamping and fixing of the spiral perforated screen filter cylinder 400 from the inside.

[0041] like Figure 5 As shown, symmetrical rotating seats 614 are provided on both sides of the rectangular shell 608. Both rotating seats 614 are rotatably connected to the rectangular shell 608. Rotating rings 612 are coaxially fixed on the outer side of both rotating seats 614. Both rotating rings 612 are rotatably connected to the rectangular shell 608. The structure of the rotating rings 612 is located inside the rectangular shell 608. The rotation of the rotating rings 612 realizes the rotation of the two rotating seats 614. A gearbox 613 is fixed on the rectangular shell 608. The gearbox 613 can drive the two rotating rings 612 to rotate synchronously. Specifically, the structure of the rotating rings 612 inside the rectangular shell 608 is a first gear. The gearbox 613 has two coaxially rotating second gears. The two second gears mesh with the two first gears respectively. The two second gears are driven by a motor. In use, the motor drives the two second gears to rotate synchronously. The synchronous rotation of the rotating rings 612 is realized through the meshing transmission of the two second gears and the two first gears, which further realizes the synchronous rotation of the two rotating seats 614.

[0042] like Figure 5As shown, two rotating seats 614 are respectively fixed with a second telescopic cylinder 616 and a second telescopic rod 615. The output ends of both second telescopic cylinders 616 are fixed with ring parts 617. The two second telescopic rods 615 are respectively fixedly connected to the ring parts 617 on both sides. Simultaneously, both ring parts 617 are slidably connected to the connecting rod 607. The connecting rod 607 is respectively fixed with a first circular limiting piece 623 and a second circular limiting piece 622 outside the two ring parts 617. The connection structures on both ring parts 617 are identical. Taking one ring part 617 as an example, specifically, the ring part 617 has two symmetrically arranged slots 618, and each slot 618 is rotatably equipped with a first brush 619. Each brush 619 has a storage groove 620 inside. A second brush 621 is rotatably mounted on one end of each of the two first brushes 619 at the storage groove 620. The second brush 621 can be rotated and stored into the storage groove 620 of the first brush 619, realizing the folding and storage of the first brush 619 and the second brush 621. A motor is provided at the rotation point of both the first brush 619 and the second brush 621, so that the first brush 619 and the second brush 621 can be rotated separately by the motor. In this embodiment, the bristles on the first brush 619 and the second brush 621 are preferably ceramic fiber bristles, with alumina and silicon dioxide as the main components, mixed with ceramic fiber reinforcement to form a brush filament structure, which has high hardness and high temperature resistance, and has the advantage of not being easily broken by repeated compression.

[0043] like Figure 5 and Figure 6 As shown, in use, after the spiral perforated screen filter cylinder 400 is cut into sections of a specified length, the slag removal assembly can be inserted into the middle position of the spiral perforated screen filter cylinder 400 by controlling the extension of the first telescopic cylinder 603. Then, by driving the bidirectional telescopic cylinder 609, the arc-shaped clamping plates 610 on both sides are moved synchronously until the two arc-shaped clamping plates 610 are respectively attached to the two sides of the spiral perforated screen filter cylinder 400, and clamping the cut spiral perforated screen filter cylinder 400 from the inside. After the arc-shaped clamping plates 610 fix the spiral perforated screen filter cylinder 400, the two second telescopic cylinders 616 respectively push the two ring parts 617 toward the two ends of the spiral perforated screen filter cylinder 400. During the pushing process, it is necessary to ensure that the first brush 619 and the second brush 621 are in a folded state. At the same time, the folded second brush 621 is completely outside the two ends of the spiral perforated screen filter cylinder 400. Then, the motor controls the four second brushes 621 to unfold, while the first brush 619 rotates at a certain angle (e.g., Figure 5The diagram shows the first brush 619 and the second brush 621 in their working state. Then, the two second telescopic cylinders 616 are controlled to retract. At this time, the first brush 619 and the second brush 621 will be located on both sides of the inner and outer walls of the spiral perforated screen filter cylinder 400, respectively. The rotation angle of the first brush 619 and the second brush 621 is adjusted so that the ceramic bristles on the first brush 619 and the second brush 621 contact the inner and outer walls of the spiral perforated screen filter cylinder 400. Then, the gearbox 613 is controlled to drive the rotating seats 614 on both sides to rotate synchronously, thereby realizing the synchronous rotation of the first brush 619 and the second brush 621 on both sides, and rotating and sweeping away the slag and nodules at the joint of the spiral perforated screen filter cylinder 400.

[0044] In actual operation, the spiral perforated screen filter cylinder 400 may also be located at its mesh opening, i.e., cut inside the mesh, which may cause slag and nodules to accumulate in the recessed areas of the cut mesh. In this case, rotational sweeping may not be able to effectively remove the slag and nodules in the recessed areas. Therefore, for the slag and nodules in the recessed areas of the mesh, we can remove them by moving the first brush 619 and the second brush 621 laterally. The specific steps are as follows: repeatedly move both ends of the spiral perforated screen filter cylinder 400 laterally, i.e., make short reciprocating movements along the connecting rod 607. The first brush 619 and the second brush 621... During the lateral movement of the brush 21, the bristles can move to the cut mesh holes and sweep them laterally. However, in actual operation, there may be situations where the complete circular holes near the cut are blocked. In this case, the present invention can completely retract the first brush 619 and the second brush 621 into the spiral perforated mesh filter cylinder 400, keep the first brush 619 horizontal or slightly open, and then rotate the second brush 621 back and forth. The ceramic bristles on the second brush 621 will push the slag and nodules in the complete circular holes outward, thereby removing the slag and nodules on the spiral perforated mesh filter cylinder 400.
