DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are involved in the scope of protection of the present application.

[0028] Reference Figures 1-10 An electric arc additive manufacturing device, comprising a device main body 1, a protective door 101 is slidably connected to one side of the device main body 1, a smoke purification device is arranged in the device main body 1, an exhaust port 2 is arranged on one side of the device main body 1, the smoke purification device comprises a purification box 201, an activated carbon plate 202 arranged in the purification box 201, a purifier 203 for purifying smoke, an air suction fan 204 arranged at the exhaust port 2, and a connecting pipe 205 for sequentially connecting the exhaust port 2, the purifier 203 and the purification box 201, the air suction fan 204 can be fixedly connected to the inside of the device main body by bolts or screws, and the purifier 203 can be selected from a three-way catalyst, a photocatalytic reactor or other devices capable of purifying smoke. The present embodiment does not make too many limitations on this.

[0029] One side of the device main body 1 is provided with a containing space 207, the purification box 201 and the purifier 203 are arranged in the containing space 207, one side of the purification box 201 away from the connecting pipe 205 is provided with an exhaust pipe 206, and the other end of the exhaust pipe 206 can be communicated with the outside; due to the saturation of the activated carbon plate 202 after long-term use, in order to facilitate the operator to replace the activated carbon plate 202, the activated carbon plate 202 and the purification box 201 are designed to be detachably connected.

[0030] In specific use, first, the protective door 101 is closed, then the equipment is started, and then the air suction fan 204 is started to work. The air suction fan 204 can suck the smoke generated during the operation of the equipment into the exhaust port 2, and the smoke can be sequentially purified by the activated carbon plate in the purifier 203 and the purification box 201, and finally, the purified smoke can be discharged through the exhaust pipe 206. By setting the smoke purification device, the smoke generated during the arc melting of the metal wire can be effectively absorbed and purified, so as to reduce the concentration of harmful substances in the air of the workshop, improve the air quality of the working area, and reduce the health risk of the operator caused by the harmful substances in the smoke. Secondly, the activated carbon plate 202 and the purification box 201 are detachably connected, which facilitates the operator to replace the activated carbon plate 202 regularly, and ensures that the purification effect of the smoke purification device is always kept in the best state.

[0031] Specifically, the box door 3 is rotatably connected to one side of the accommodation space 207, the activated carbon plate 202 is provided with the mounting frame 301 around, the purification box 201 is provided with the opening 302 at the top, the mounting frame 301 is slidably connected with the opening 302 (a sealing gasket can be arranged at the opening 302 to increase the sealing performance of the mounting frame 301 and the opening 302), the purification box 201 is internally provided with the purification space 303, the bottom of the purification space 303 is provided with the two fixed blocks 304, and the installation groove 305 is formed between the two fixed blocks 304. The side of the mounting frame 301 close to the fixed block 304 is provided with the clamping groove 306, the side of the fixed block 304 close to the clamping groove 306 is provided with the clamping block 307 which is clamped with the clamping groove 306, and the fixed block 304 is internally provided with the sliding mechanism which makes the clamping block 307 disengage from the clamping groove 306. If the fixing effect is to be improved, multiple clamping blocks 307 and clamping grooves 306 can be arranged.

[0032] When the operator needs to replace the activated carbon plate 202, the clamping block 307 can be disengaged from the clamping groove 306 through the sliding mechanism to complete the disassembly. The clamping mode can simplify the installation and replacement process of the activated carbon plate 202, and tools are not required, thereby improving the convenience of operation.

[0033] Further, the fixed block 304 close to the clamping groove 306 is provided with the accommodation groove 308 which is slidably connected with the clamping block 307, the bottom of the accommodation groove 308 is provided with the limiting groove 309, the bottom of the clamping block 307 is provided with the limiting block 310 which is slidably connected with the inside of the limiting groove 309, the bottom of the limiting groove 309 is provided with the sliding groove 311, the sliding mechanism includes the sliding block 4 which is slidably connected with the inner wall of the sliding groove 311, the first elastic member 401 which is arranged between the side of the sliding groove 311 and the sliding block 4, and the pressing rod 402 which is arranged on the side of the sliding block 4 away from the first elastic member 401, one end of the first elastic member 401 is fixedly connected with the side of the sliding groove 311, and the other end of the first elastic member 401 is fixedly connected with the sliding block 4.

[0034] The sliding block 4 is provided with a sliding groove 403, and the sliding groove 403 is arranged downwardly from the side of the sliding block 4 close to the clamping groove 306 to the side of the sliding block 4 away from the clamping groove 306. The bottom of the limiting block 310 is provided with a sliding column 404 which is in sliding connection with the inner wall of the sliding groove 403. The sliding column 404 can be designed as a cylindrical structure as a whole, and the arc surface thereof can reduce the contact area between the sliding column 404 and the sliding groove 403 as much as possible, thereby reducing the friction and making the sliding column 404 move more smoothly in the sliding groove 403 and reducing the occurrence of the blocking phenomenon.

[0035] When the operator needs to disassemble the activated carbon plate 202, the pressing rod 402 is only pressed. The pressing rod 402 will drive the sliding block 4 to move along the inner wall of the sliding groove 311 in the direction of compressing the first elastic member 401. At the same time, the limiting groove 309 limits the freedom of the limiting block 310, so that the limiting block 310 can only move along the inner wall of the limiting groove 309. Therefore, when the sliding block 4 moves in the direction of compressing the first elastic member 401, the sliding column 404 will drive the limiting block 310 to move away from the clamping groove 306 under the action of the sliding groove 403, so that the clamping block 307 is retracted into the accommodating groove 308 and separated from the clamping groove 306. At this time, the operator can disassemble the activated carbon plate 202. In the embodiment, the sliding mechanism only needs to be pressed by the operator to press the pressing rod 402, so that the activated carbon plate 202 can be disassembled, and the convenience of disassembling or replacing the activated carbon plate 202 is further improved.

[0036] When the operator takes out the activated carbon plate 202 and releases the pressing rod 402, the first elastic member 401 will recover the deformation, so as to drive the sliding block 4 to return to the original position, and the clamping block 307 will also be extended again under the action of the sliding groove 403. In order to ensure that the sliding block 4 can effectively drive the clamping block 307 to return to the extended position when the operator releases the hand, the third elastic member 503 is arranged in the accommodating groove 308. One end of the third elastic member 503 is fixedly connected to the side of the accommodating groove 308 away from the clamping block 307, and the other end is fixedly connected with the clamping block 307. The handle 603 is arranged on the side of the mounting frame 301 away from the fixed block 304. When the clamping block 307 is retracted into the accommodating groove 308, the clamping block 307 will compress the third elastic member 503 at the same time. When the operator releases the hand, the first elastic member 401 and the third elastic member 503 will recover the deformation at the same time, so as to drive the clamping block 307 to extend again. By arranging the third elastic member 503, the reliability and stability of the sliding mechanism under long-time use can be improved. The handle 603 is arranged to facilitate the operator to exert force to take out the activated carbon plate 202.

[0037] Secondly, in order to facilitate the operator to press the pressure rod 402, the side of the pressure rod 402 away from the elastic part passes through the side of the purification box 201 and extends to the outside of the purification box 201, and the side of the pressure rod 402 away from the purification box 201 is in an arc shape. Compared with sharp or angular designs, the arc shape is safer and reduces the risk of accidental injury to the hands during operation.

[0038] In addition, an elastic mechanism is also provided in the mounting groove 305, the elastic mechanism including a rebound plate 5 and a plurality of second elastic members 501 (the second elastic members 501 in the illustrated state are in a compressed state), one end of each second elastic member 501 is fixedly connected to the bottom of the mounting groove 305, and the other end of each second elastic member 501 is fixedly connected to the rebound plate 5, the rebound plate 5 is slidingly connected to the inner wall of the mounting groove 305, and the rebound plate 5 is abutted against the bottom of the mounting frame 301 (the abutment means that the two are in contact). By providing the elastic mechanism, when the block 307 is disengaged from the slot 306, the mounting frame 301 is automatically ejected from the opening 302, thereby facilitating the operator to remove the activated carbon plate 202, thereby improving the convenience of operation. The rebound plate 5 is slidingly connected to the inner wall of the mounting groove 305, which can prevent the rebound plate 5 from being offset or dislocated when subjected to force, thereby ensuring that each second elastic member 501 is evenly stressed, thereby improving the service life of the elastic member.

[0039] In this embodiment, to facilitate the operator's installation of the activated carbon plate 202, positioning blocks 601 are provided on both sides of the installation frame 301, and positioning grooves 602 are provided on both sides of the purification space 303. The positioning blocks 601 are slidably connected to the inner walls of the positioning grooves 602, and the positioning grooves 602 should be coplanar with the installation grooves 305. The positioning blocks 601 and positioning grooves 602 allow the operator to more conveniently align and secure the activated carbon plate 202 during installation, ensuring that the position of the activated carbon plate 202 corresponds to the position of the installation grooves 305, reducing the need to judge and adjust the installation position and improving installation efficiency.

[0040] Secondly, the bottom corners of the mounting frame 301 are designed with an arc-shaped structure. The side of the clamping block 307 near the clamping slot 306 is provided with a first inclined surface 502 that is slidably connected to the bottom of the mounting frame 301. This allows the operator to install the activated carbon plate 202 without using a sliding mechanism to retract the clamping block 307. The operator only needs to apply sufficient force to overcome the resistance of the first elastic member 401 and the third elastic member 503 to retract the clamping block 307 into the receiving slot 308. When the position of the clamping block 307 is aligned with the clamping slot 306, the clamping block 307 will automatically snap into the clamping slot 306 on the mounting frame 301 under the action of the first elastic member 401 and the third elastic member 503, thereby achieving fixation.

[0041] Working principle:

[0042] In use, first, the protection door 101 is closed, then the equipment is started, and then the air suction fan 204 is started to work.

[0043] When the activated carbon plate 202 needs to be replaced, the box door 3 is opened, and then the pressing rod 402 is pressed, the pressing rod 402 drives the sliding block 4 to move along the inner wall of the sliding groove 311 to the direction of compressing the first elastic member 401.

[0044] When the operator needs to install the activated carbon plate 202, the installation frame 301 with the side of the clamping groove 306 is correspondingly arranged at the position of the clamping block 307, and then the positioning block 601 is inserted into the positioning groove 602, and when the bottom of the installation frame 301 is in contact with the clamping block 307, the operator needs to exert sufficient force to overcome the resistance of the first elastic member 401 and the third elastic member 503, so that the clamping block 307 is retracted into the containing groove 308.

[0045] The above is only a preferred embodiment of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
