[0072] It should also be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings. Unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other.

[0073] It should be noted that the concepts of "first" and "second" mentioned in this disclosure are used only to distinguish different devices, modules or units, and are not used to limit the order of functions performed by these devices, modules or units or their interdependencies.

[0074] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0075] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0076] Reference Figure 1-9A baffle for laser cutting equipment includes: a connecting plate 101, a replacement plate 102, an abutment ring 103, and an abutment block 104. The connecting plate 101 is fixed to the laser cutting machine and moves up and down. A mounting hole 101a is provided on the connecting plate 101. The replacement plate 102 is installed in the mounting hole 101a. A conical groove 102a and a through hole 102b are provided on the replacement plate 102. The through hole 102b is located at the center of the conical groove 102a, and its diameter is only slightly... The diameter of the laser is larger than that of the laser, and the laser passes through the perforation 102b to cut the metal plate; the abutment ring 103 is fixed on the inner wall of the mounting hole 101a and abuts against the bottom surface of the replacement plate 102, and is used to support the replacement plate 102 upward. The abutment block 104 is integrally formed on the lower end surface of the replacement plate 102. The abutment block 104 is integrally formed below the replacement plate 102 and is located at the perforation 102b. The perforation 102b passes through the abutment block 104, and the abutment block 104 abuts against the metal plate.

[0077] When a laser cuts a metal plate, the cut portion melts into molten metal. This molten metal splashes onto the surface of the conical groove 102a, preventing it from splashing onto the metal plate. Without the protection of the baffle, the cooled molten metal would become metal waste and stick to the surface of the metal plate, greatly reducing its surface finish. To improve the surface finish, the metal plate would need to be polished a second time, wasting manpower and resources and reducing work efficiency.

[0078] By using baffles to block the flow, the risk of molten metal splashing onto the metal plate is greatly reduced, saving time that would otherwise be spent on secondary polishing and effectively improving work efficiency.

[0079] During prolonged cutting operations, cooled molten metal will accumulate on the surface of the conical groove 102a, necessitating the replacement plate 102. The replacement plate 102 reduces the cost of each replacement, requiring only partial replacement instead of replacing all the baffles.

[0080] A mounting groove 102c is provided on the lower end face of the replacement plate 102. The inner wall of the mounting groove 102c is annular and has threads. A mounting plate 105 is threaded onto the mounting groove 102c, which closes the mounting groove 102c. A positioning sleeve 106 is rotatably provided on the upper end face of the mounting plate 105. The positioning sleeve 106 is annular and a magnetic ring 107 is fixed inside the positioning sleeve 106. The magnetic ring 107 abuts against the bottom surface of the mounting groove 102c and is used to absorb the cooled molten metal splashed into the conical groove 102a.

[0081] When molten metal splashes onto the surface of the conical groove 102a, it will roll along the groove surface of the conical groove 102a toward the perforation 102b. If no obstruction is made, the molten metal will roll through the perforation 102b onto the metal plate or block the perforation 102b.

[0082] With the magnetic ring 107 in place, when the molten metal rolls down, the magnetic ring 107 will attract the molten metal, preventing it from rolling down and fixing it above the perforation 102b for later unified recycling.

[0083] A drive assembly 108 for driving the connection plate 101 to rotate is installed on the connection plate 101. The drive assembly 108 includes: a slide rod 108a, a first rotating shaft 108b, a second rotating shaft 108c, a timing belt 108d, a drive component 108e, and a gear 108f. A sliding groove 102d is formed on the connection plate 101 and the replacement plate 102 for the slide rod 108a to slide. The sliding groove 102d passes through one side of the replacement plate 102, allowing the slide rod 108a to extend into the mounting groove 102c. The slide rod 108a is slidably disposed in the sliding groove 102d. The first rotating shaft 108b is rotatably disposed in the sliding groove 102d. One end of the rod 108a; the second rotating shaft 108c is rotatably mounted on the slide rod 108a at the end away from the first rotating shaft 108b; the synchronous belt 108d is sleeved on the outside of the first rotating shaft 108b and the second rotating shaft 108c; the driving member 108e can be an electric motor, and the driving end of the driving member 108e is connected to the second rotating shaft 108c to drive the second rotating shaft 108c to rotate; the gear 108f is fixed on the first rotating shaft 108b; a toothed groove 106a that meshes with the gear 108f is provided on the outer wall of the positioning sleeve 106 so that the gear 108f drives the positioning sleeve 106 to rotate.

[0084] A slider 109 is slidably connected to the connecting plate 101, and a driving component 108e is fixed to the slider 109. A connecting rod 110 is fixed to the slider 109, and a magnetic suction rod 111 is hinged to one end of the connecting rod 110 away from the slider 109. The lower end face of the magnetic suction rod 111 has a magnet so that the magnetic suction rod 111 can collect metal fragments in the conical groove 102a.

[0085] When collecting molten metal fragments in the conical groove 102a, the operator slides the slider 109, causing the magnetic rod 111 to abut against the surface of the conical groove 102a. At the same time, the gear 108f is inserted into the tooth groove 106a, causing the positioning ring and the magnetic ring 107 to rotate. The molten metal fragments attracted by the magnetic ring 107 rotate around the perforation 102b in the conical groove 102a, and then come into contact with the magnetic rod 111 and are attracted by it. After the magnetic ring 107 rotates a few times, the magnetic rod 111 collects all the molten metal fragments in the conical groove 102a, making it convenient to collect and process the metal fragments.

[0086] The magnetic rod 111 can also be made of electromagnet to facilitate the removal of metal fragments from the magnetic rod 111.

[0087] The connecting rod 110 also has a storage groove 110a for storing the magnetic rod 111. The storage groove 110a is located on the upper end surface of the connecting rod 110. When you want to store the magnetic rod 111, you only need to bend the magnetic rod 111 upward and put the magnetic rod 111 into the storage groove 110a.

[0088] Before the molten metal splashes onto the surface of the conical groove 102a, the operator can first place the magnetic rod 111 into the receiving groove 110a, then activate the drive component 108e and push the slider 109, causing the gear 108f to rotate the positioning ring, which in turn causes the magnetic ring 107 to rotate. When the molten metal splashes onto the surface of the conical groove 102a, the molten metal is attracted by the magnetic ring 107, which causes the molten metal to roll on the surface of the conical groove 102a. This prevents the molten metal from sticking to the surface of the conical groove 102a after cooling, thus extending the service life of the replacement plate 102.

[0089] When the magnetic ring 107 drives the molten metal to rotate, it can accelerate the cooling of the molten metal. The shorter the cooling time of the molten metal, the less damage it causes to the replacement plate 102, thereby extending the service life of the replacement plate 102.

[0090] When you want to use the magnetic rod 111 to collect the cooled molten metal in the conical groove 102a, you need to pry the magnetic rod 111 out of the receiving groove 110a and let the magnetic rod 111 come into contact with the conical groove 102a.

[0091] The baffle for the laser cutting equipment also includes: a rod 112 and a bolt 113; a through groove 101b is provided on the side wall of the connecting plate 101, and the rod 112 is inserted into the through groove 101b; a slot 102e is provided on the side wall of the replacement plate 102, and the rod 112 passes through the through groove 101b and is inserted into the slot 102e and fixed to the connecting plate 101 by the replacement plate 102; the connecting plate 101 has a fixing hole 101c, and the rod 112 has a threaded groove 112a. The bolt 113 is inserted into the fixing hole 101c and then threaded into the threaded groove 112a to fix the rod 112 to the connecting plate 101.

[0092] One end of the connecting plate 110 is fixed to the hydraulic cylinder 114. The hydraulic cylinder 114 is fixed to the laser cutting machine by the fixing plate 115. The hydraulic cylinder 114 can drive the connecting plate 110 to move up and down.
