DETAILED DESCRIPTION

[0059] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0060] like Figures 1 to 14 As shown, the present embodiment proposes a noise reduction and environmental protection equipment for cutting plates, comprising a cutting table 1, a movable frame 2 located above the cutting table 1 for installing a processing device, and a noise reduction and dust removal mechanism, wherein the noise reduction and dust removal mechanism comprises: a silencer 16 having a cavity, slidably arranged on the cutting table 1, and the inner wall of the cavity abuts against the movable frame 2; a first smoke exhaust channel 3, arranged on the movable frame 2 and located in the silencer 16, and the first smoke exhaust channel 3 moves synchronously with the movable frame 2; a second smoke exhaust channel 4, arranged on one side of the cutting table 1 and located in the smoke hood, one end of the first smoke exhaust channel 3 is slidably arranged on the upper surface of the second smoke exhaust channel 4, and the second smoke exhaust channel 4 is connected to the first smoke exhaust channel; a first filter element 5, arranged on one side of the outlet of the second smoke exhaust channel 4; a second filter element 6, arranged on one side of the outlet of the first filter element 5, and an air outlet is provided at one end of the second filter element 6 away from the first filter element 5.

[0061] In the above scheme, the silencer 16 can be arranged on the cutting table in two ways. First, a mounting opening 18 of the same shape as the end face of the cutting table 1 is opened on the silencer 16, and the silencer 16 is directly mounted on the cutting table 1 through the mounting opening 18. It should be noted that the movable frame 2, the first smoke exhaust channel 3 and the second smoke exhaust channel 4 are all located in the silencer 16, and the silencer 16 is slidably connected to the cutting table 1. When the movable frame 2 moves, the movable frame 2 and the silencer 16 are driven to move, thereby improving the noise reduction effect during the cutting operation.

[0062] The second type is to arrange two guide rails on both sides of the bottom of the cutting table 1. The setting direction of the guide rails is the same as the moving direction of the mobile frame 2. A column is installed on the outer wall of the silencer 16. The column is slidably connected to the guide rail. A motor can be added to the silencer 16. When the mobile frame 2 moves, the motor will drive the silencer 16 to move, so that the mobile frame 2 is always located in the middle of the inner side of the silencer 16, thereby improving the mute effect. It should also be noted that a sound-absorbing and insulating composite board is fixedly arranged inside the silencer 16 to absorb noise. By setting a slide rail, the silencer 16 can move left and right, which is convenient for cleaning and maintenance of the cutting equipment. The silencer 16 can absorb the noise generated during cutting, thereby reducing the propagation of noise and reducing the harm caused by noise to the user, thereby improving the practicality of the device and meeting the user's use needs. The front and back of the silencer 16 are both double-door types, which can facilitate the forward and backward movement of the silencer 16 and the cleaning and maintenance of the cutting machine. The silencer 16 is composed of a sound-absorbing and insulating composite board and its supporting structure.

[0063] The first smoke exhaust channel 3 can move synchronously with the mobile frame 2. When performing cutting operations, the first smoke exhaust channel 3 can timely absorb and collect the generated smoke to prevent the smoke from harming the health of the operator and also help reduce the pollution of the smoke to the air. In addition, since the length of the first smoke exhaust channel 3 is the same as the length of the mobile frame 2, when the cutting gun moves horizontally along the mobile support, the first smoke exhaust channel 3 can also quickly collect the smoke, thereby improving the smoke collection rate.

[0064] It should be noted that the second smoke exhaust channel 4 is arranged on a side away from the operator to prevent the second smoke exhaust channel 4 from affecting the operator's operation. Secondly, the first filter 5 and the second filter 6 are both located outside the cutting table 1 and will not hinder the operator.

[0065] Furthermore, the silencer cover 16 further includes: a base 17, which is located below the silencer cover 16 and fixedly connected to the bottom of the base 17, and the base 17 is used to hold the debris generated when cutting the workpiece.

[0066] In the above scheme, during the cutting operation, the material on the cutting table can fall from the gap of the cutting table and fall onto the bottom support for collecting the waste chips.

[0067] Furthermore, the first smoke exhaust channel 3 includes: a first pipe 301, which is located above the movable frame 2, and a plurality of air holes 302 for smoke intake are opened on the side of the first pipe 301 facing the movable frame 2; a second pipe 303, which is arranged at the end of the first pipe 301, and the first pipe 301 and the second pipe 303 are arranged in an L shape, and an end of the second pipe 303 away from the first pipe 301 is located above the second smoke exhaust channel 4; a first fan 304, which is arranged in the second pipe 303; a first smoke hood 8, which is arranged on the first pipe 301, and the first smoke hood 8 is arranged directly above the movable frame 2; a second smoke hood 10, which is arranged at the end of the second pipe 303 away from the first pipe, and the second smoke hood 10 is slidably connected to the second smoke exhaust channel 4.

[0068] In the above scheme, the first fume hood 8 can increase the fume collection area of ​​the first pipe 301, further preventing the fume from diffusing into the air, and a glass window 9 is provided on the first fume hood 8, so that external light can enter the movable rack 2 through the glass window 9, thereby improving the brightness of the movable rack 2 and facilitating observation by the operator.

[0069] Secondly, the second fume hood 10 is rectangular, and the second fume hood 10 can directly discharge the smoke in the second pipe 303 into the third pipe 401. The first fan 304 in the second pipe 303 is an exhaust fan. Through the operation of the first fan 304, the generated smoke can be sucked into the first pipe 301 and transported from the first pipe 301 to the second pipe 303. It can be understood that the operating power of the first fan 304 can be adjusted according to the size of the smoke.

[0070] Furthermore, the second smoke exhaust channel 4 includes: a third pipe 401, which is horizontally arranged along the moving direction of the movable frame 2, and the third pipe 401 is arranged on the side wall of the cutting table 1, and the third pipe 401 is located below the second pipe 303; one end of the third channel is connected to the first filter element 5; there are multiple through holes 402, and the multiple through holes 402 are evenly spaced on the upper surface of the third pipe 401, and the through holes 402 are connected to the second smoke hood 10; there are multiple baffles 403, the baffles 403 correspond to the through holes 402 one by one, and the baffles 403 are rotatably set on the through holes 402.

[0071] In the above scheme, the baffle 403 will only be opened by the attraction of the electromagnet when the second fume hood 10 moves to the top of the through hole 402, and when the second fume hood 10 moves away from the corresponding through hole 402, the baffle 403 will fall down to cover the through hole 402 for smoke to be discharged. It can be understood that in order to prevent the baffle 403 from affecting the movement of the second fume hood 10 during the falling process, two groups of electromagnets 101 are provided at the bottom of the second fume hood 10, and the two groups of electromagnets 101 are respectively provided at the two ends of the opening of the second fume hood 10. When the second fume hood 10 moves, the electromagnet 101 whose setting position in the second fume hood 10 is consistent with the moving direction of the second fume hood 10 is powered on and started.

[0072] Furthermore, the noise reduction and dust removal mechanism is also provided with a control component, which includes: an electromagnet 101, which is provided in the second fume hood 10; a plurality of iron sheets 404, each of which is provided with an iron sheet 404 on the baffle 403, and the electromagnet 101 attracts the corresponding iron sheet 404. The electromagnet 101 can be kept powered on during use. It should be noted that when the second fume hood 10 drives the electromagnet 101 to separate from the attracted iron sheet 404, the electromagnet 101 and the iron sheet 404 are separated under the pull of the second fume hood 10.

[0073] Furthermore, the first filter element 5 includes: a connecting pipe 11, which is arranged at one end of the third pipe 401 and connected to the third pipe 401, and a second fan 13 is arranged in the connecting pipe 11; a U-shaped tube, having an air inlet end 501 and an air outlet end 502, the air inlet end 501 is connected to the connecting pipe 11, and the air outlet end 502 is connected to the second filter element 6; the U-shaped tube is filled with water; an insertion tube 503, which is arranged in the U-shaped tube, the inlet of the insertion tube 503 is connected to the air inlet end 501, and the other end of the insertion tube 503 is located in the water.

[0074] In the above scheme, the smoke in the third pipe 401 is sucked into the connecting pipe 11 under the action of the second fan 13, and enters the water in the U-shaped pipe through the connecting pipe 11 and the insertion pipe 503, and the smoke and dust impurities inside are initially filtered, and the water-insoluble part is discharged into the second filter element 6 through the gas outlet end 502. It should be noted that the gas outlet end 502 of the connecting pipe 11 is provided with a flange 12, and there is also a flange 12 at the end of the U-shaped pipe. After a period of use, the U-shaped pipe can be cleaned and the water can be changed by removing the bolts at the flange 12.

[0075] It should also be noted that since the power of the first fan 304 and the second fan 13 of the device is relatively large, in addition to the flue gas, larger particles of dust and other impurities in the air will be sucked into the noise reduction and dust removal mechanism. Therefore, a filter plate 14 is provided at the air inlet of the U-shaped tube to filter the above-mentioned large particles of impurities.

[0076] Furthermore, the second filter element 6 includes: a smoke exhaust pipe 601, which is connected to the U-shaped pipe and is provided with a plurality of slots 602; and a plurality of filter plates 603, which correspond to the slots 602 one by one and are slidably connected to the slots 602. The slots 602 are used to plug in a plurality of filter plates 603, and different filter plates 603 can be placed with different filters, such as activated carbon, filter cotton, etc. The filler in the filter plate 603 is the prior art and will not be described in detail here.

[0077] Furthermore, the first smoke channel also includes: a cover plate 7, which is hinged to one end of the first pipe 301 away from the second pipe 303, and the cover plate 7 is used to cover the end of the first pipe 301. The cover plate 7 is closed during smoke exhaust. When the first pipe 301 needs to be cleaned, the cover plate 7 is opened and then the inside is cleaned with a cleaning tool to clean the smoke residue attached to the first pipe 301. Similarly, a reversible cover plate 7 is provided at one end of the third pipe 401, and its structure is the same as that of the cover plate 7, which will not be described in detail here. It should be noted that since both ends of the second pipe 303 are open structures, when the inside of the second pipe 303 needs to be cleaned, it is only necessary to remove the second pipe 303.

[0078] Furthermore, a slide groove 407 is provided on the upper surface of the third pipe 401, and the second smoke hood is slidably connected to the slide groove 407. In order to enhance the sealing performance of the connection between the second smoke hood 10 and the third pipe 401, extended convex strips are provided on both sides of the bottom of the second smoke hood, and the convex strips are slidably connected to the slide groove 407, and the surface of the second smoke hood 10 is in direct contact with the surface of the third pipe 401.

[0079] Furthermore, a limit strip 405 is provided in the through hole 402, and a groove 406 is provided on the baffle 403, and the groove 406 is limitedly connected to the limit strip 405. It should be noted that in order to prevent the baffle 403 from deflecting downward by itself, a limit strip 405 is provided on one side below the baffle 403. Under the action of gravity, the baffle 403 covers the through hole 402 to prevent smoke from escaping. When the iron sheet 404 of the baffle 403 is attracted by the electromagnet 101, the baffle 403 will deflect upward and open.

[0080] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
