Description

Technical Field

[0001] The invention relates to the technical field of laser processing, in particular to a smoke exhaust and dust removal device for a cutting machine. Background Art

[0002] The laser cutting machine uses a high-power density laser beam to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature and evaporated to form holes. As the beam moves on the material, the holes continuously form a very narrow (such as about 0.1mm) slit to complete the cutting of the material. In the laser cutting process, a large amount of waste, dust particles and dust smoke will be generated. The dust smoke generated has a strong irritating smell and contains a small amount of toxic gases. After being absorbed by the human body, it will seriously endanger the health of the operator and pollute the surrounding environment. At the same time, if the dust is not handled in time, it will also cause corrosion to the parts of the cutting equipment.

[0003] During the laser cutting process, iron chips will be generated. These iron chips are formed by the interaction between the laser and the material, melting or evaporating the material. The generation of iron chips will not only affect the quality and accuracy of the cutting, but may also cause blockage or other failures to the laser cutting machine, so they need to be cleaned up in time.

[0004] The existing technology usually uses a fan to exhaust the iron filings and smoke during the exhaust process to further ensure the cutting effect. However, this method has certain disadvantages, especially it is difficult to collect the iron filings in a unified manner. Iron filings have certain utilization value and can be converted into valuable resources through recycling. For example, iron filings can be used in metal smelting as a substitute for scrap steel, reducing the demand for new iron ore. In addition, iron filings can also be processed through specific processes to produce chemicals such as ammonium ferrous sulfate.

[0005] Therefore, we propose a smoke exhaust and dust removal device for a cutting machine. Summary of the invention

DETAILED DESCRIPTION

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Example 1, reference Figures 1 to 3 , which is the first embodiment of the present invention, provides a smoke exhaust and dust removal device for a cutting machine. While exhausting the smoke generated during the laser operation, it will also collect iron filings. In addition, in order to prevent the iron filings from clogging the filter screen during the collection process, the screening component for collecting the iron filings can also avoid clogging by means of vibration.

[0029] Specifically, the supporting assembly 100 includes an outer box body 101, an operating panel 101a integrally formed on the end surface of the outer box body 101, a grille 101a-1 arranged in the operating panel 101a, and a fan 102 arranged outside the outer box body 101 and capable of exhausting smoke from the operating panel 101a; wherein, laser cutting work can be carried out in the operating panel 101a, and metal objects are placed on the grille 101a-1. The smoke and iron filings generated during the laser process will pass through the gaps between the grilles 101a-1 and be uniformly input into the outer box body 101 by the fan 102.

[0030] The screening component 200 includes a first inner drawer 201 detachably disposed in the outer box body 101 and a screen 202 disposed in the first inner drawer 201; wherein, when the fan 102 is performing smoke exhaust work, the first inner drawer 201 will vibrate slightly in the outer box body 101 to accelerate the completion of the screening work.

[0031] In summary, when performing laser cutting operations, the object to be cut is placed on the grille 101a-1. During this process, the first inner drawer 201 needs to be inserted into the outer box body 101. While the smoke is discharged by the fan 102, the iron filings generated during the cutting process will be intercepted by the screen 202 and collected on the first inner drawer 201.

[0032] It should be noted that if the collected iron filings need to be obtained, the first inner drawer 201 can be pulled out after the laser operation is completed. Therefore, the connection method between the first inner drawer 201 and the outer box body 101 is very important, which should have a quick release function and still be able to move to a certain extent after connection, so as to produce a vibration effect to prevent the screen 202 from being blocked.

[0033] Example 2, reference Figure 1~Figure 5 , which is the second embodiment of the present invention. Different from the previous embodiment, a connection method between the first inner drawer 201 and the outer box body 101 is provided to ensure that when the first inner drawer 201 is fixed in the outer box body 101, the first inner drawer 201 can still move but not separate from the outer box body 101.

[0034] Specifically, the inner cavity of the outer box body 101 is provided with an active channel 101b for pulling out the first inner drawer 201, and an air suction port 102a is provided in the active channel 101b. The active channel 101b will support the displacement of the first inner drawer 201, and make the first inner drawer 201 only capable of linear movement and not rotation. The air inlet duct of the fan 102 will be connected to the air suction port 102a.

[0035] The outer wall of the outer box body 101 is provided with a first straight groove 103, and a limiting end 104 is provided outside the outer box body 101; wherein the limiting end 104 includes a second straight groove 104a, and a first clamping groove 104b and a second clamping groove 104c which are respectively provided at both ends of the second straight groove 104a and communicated with the second straight groove 104a. Figure 2 It can be seen that the first straight slot 103 is located above the limiting end 104 .

[0036] The device also includes a limit position assembly 300, which includes a crossbeam 301 movably disposed in the first straight groove 103 and a clamping rod 302 movably disposed in the second straight groove 104a, wherein a connecting arm 303 is threadedly connected between the clamping rod 302 and the crossbeam 301. Figure 1 The crossbeam 301 passes through the first straight slot 103, and the limiting assembly 300 is in a beveled state in a static state. Only when the limiting assembly 300 is located on both sides of the first straight slot 103, it will rotate. During the rotation process, the first inner drawer 201 will be locked or unlocked respectively.

[0037] Tension springs D are arranged on both sides of the outer wall of the outer box body 101, and one end of the two tension springs D is connected to the clamping rod 302. When the limiting assembly 300 is in the middle position of the first straight slot 103, each tension spring D is not subjected to force.

[0038] The outer wall of the first inner drawer 201 is provided with a limiting groove 201a movably connected to the clamping rod 302. The limiting groove 201a is symmetrically provided on both sides of the outer wall of the first inner drawer 201, and is movably connected to the two clamping rods 302 on the limiting assembly 300 respectively.

[0039] In summary, when laser cutting is to be performed, the first inner drawer 201 needs to be inserted into the outer box body 101 along the movable channel 101b. When the first inner drawer 201 contacts the crossbeam 301, the first inner drawer 201 will push the crossbeam 301 to move to the right side of the first straight groove 103. When the crossbeam 301 moves to contact the right side wall of the first straight groove 103, the limit assembly 300 will rotate with the crossbeam 301 as the axis, and the clamping rod 302 in the limit assembly 300 will rotate from the second straight groove 104c to the first clamping groove 104b, and enter the limit groove 201a of the first inner drawer 201 under the action of the tension spring D. At this time, the first inner drawer 201 is stopped from being pushed, and the first inner drawer 201 rebounds, driving the limit assembly 300 to return to the middle position, thereby completing the connection between the outer box body 101 and the first inner drawer 201.

[0040] When the outer box body 101 is connected to the screening assembly 200 through the limiting assembly 300, the first inner drawer 201 in the screening assembly 200 can still move in the outer box body 101, and the movement of the first inner drawer 201 will not cause it to be separated from the outer box body 101. When the first inner drawer 201 needs to be removed from the outer box body 101, the first inner drawer 201 is pulled so that the crossbeam 301 moves to the left side of the first straight groove 103 and contacts it, and the limiting assembly 300 will rotate and rotate the clamping rod 302 from the second straight groove 104a to the second clamping groove 104c. At this time, the clamping rod 302 will be released from the limiting groove 201a, and the limiting assembly 300 will no longer limit the first inner drawer 201, so that it is convenient for the staff to obtain the iron filings collected in the first inner drawer 201.

[0041] Example 3, reference Figure 1~Figure 5 , which is the third embodiment of the present invention, is different from the previous embodiment in that the iron filings collection effect of the screening component 200 is further optimized.

[0042] Specifically, a transmission member 204 is provided at the bottom of the first inner drawer 201, and the transmission member 204 includes a transmission groove 204a extending through the other end surface of the first inner drawer 201. The transmission groove 204a is also a smoke exhaust groove, and smoke will enter the air inlet 102a through the transmission groove 204a.

[0043] A rotating shaft 204b is rotatably disposed in the transmission slot 204a, and an eccentric wheel 204c which is not located on the same axial direction as the rotating shaft 204b is sleeved on the outer wall of the rotating shaft 204b, and a fan guide 204c-1 is disposed on the outer wall of the eccentric wheel 204c. The wind force brought by the fan 102 will drive the eccentric wheel 204c to rotate eccentrically through the fan guide 204c-1, and during this eccentric rotation, the first inner drawer 201 will be pushed to vibrate to a certain extent.

[0044] The second inner drawer 203 is movably arranged in the first inner drawer 201, and a handle 203a is installed on the end surface of the second inner drawer 203 through a thread. The first inner drawer 201 and the second inner drawer 203 will screen the iron filings in the cutting operation according to the volume through the screen 202, and the iron filings with a smaller volume will be discharged by the fan 102 after passing through the screen 202.

[0045] The end surface of the outer box body 101 is provided with a tool groove 101c, and the bottom corners of the outer box body 101 are provided with supporting feet 101d. The supporting feet 101d support the entire device.

[0046] It should be noted that the tool slot 101c will enable the device as a whole to have a certain storage function, providing certain convenience for the work of the operator.
