[0027] Please refer to Figures 1 - 6 As shown, an intake square pipe for etching includes a quadrilateral pipe 1. A fixing block 2 is fixedly connected to the top of the quadrilateral pipe 1. A motor 3 is fixedly connected to the rear of the fixing block 2. A dust-proof filtering mechanism 4 is arranged inside the quadrilateral pipe 1. A sweeping mechanism 5 is also arranged inside the quadrilateral pipe 1. The dust-proof filtering mechanism 4 includes a reciprocating lead screw 401, a positive magnet block 402, and a negative magnet block 403. The reciprocating lead screw 401 is fixedly connected to the output end of the motor 3. The positive magnet block 402 is threadedly connected to the surface of the reciprocating lead screw 401. The negative magnet block 403 is slidably connected to the inner top wall of the quadrilateral pipe 1 by magnetism. The dust-proof filtering mechanism 4 further includes a square frame 404, a cleaning head 405, and a filter net 406. The bottom of the negative magnet block 403 is fixedly connected to the square frame 404. The cleaning head 405 is fixedly connected to the surface of the square frame 404. The filter net 406 is fixedly connected to the inner wall of the square frame 404. The surface of the reciprocating lead screw 401 is rotatably connected to the inner wall of the fixing block 2. The bottom of the positive magnet block 402 is in contact with the top of the quadrilateral pipe 1. The port of the cleaning head 405 is in contact with the inner wall of the quadrilateral pipe 1. The motor 3 drives the reciprocating lead screw 401 to rotate, so that the reciprocating lead screw 401 drives the positive magnet block 402 on its surface to perform a reciprocating motion along the spiral groove on its surface. Under the magnetic attraction of the positive magnet block 402 and the negative magnet block 403, the negative magnet block 403 is driven to perform a reciprocating motion along the inner top wall of the quadrilateral pipe 1. The negative magnet block 403 drives the square frame 404 to move, and the square frame 404 drives the cleaning head 405 connected to its surface to perform a reciprocating cleaning operation on the inner wall of the quadrilateral pipe 1, so as to sweep down some dust and dirt attached to the inner wall of the quadrilateral pipe 1. At the same time, the filter net 406 intercepts some impurities and dust carried in the airflow during intake, preventing dust and impurities from entering the etching working area through the square pipe.
[0028] Embodiment 2
[0029] Please refer to Figures 1 - 6As shown in the figure, the cleaning mechanism 5 includes a connecting rod 501, a pushing plate 502, and a sliding rod 503. The connecting rod 501 is fixedly connected to the front part of the square frame 404. The pushing plate 502 is fixedly connected to the front part of the connecting rod 501. The sliding rod 503 is fixedly connected to the left side of the pushing plate 502. The cleaning mechanism 5 further includes a sliding groove 504, a rotating rod 505, and a guide block 506. The sliding groove 504 is formed in the inner wall of the quadrilateral tube 1. The rotating rod 505 is rotatably connected to the inner wall of the sliding groove 504. The guide block 506 is fixedly connected to the surface of the rotating rod 505. One end of the connecting rod 501 away from the square frame 404 is slidably connected to the inner wall of the pushing plate 502. The surface of the sliding rod 503 is slidably connected to the inside of the sliding groove 504. The bottom of the pushing plate 502 is in contact with the bottom wall inside the quadrilateral tube 1. The square frame 404 drives the connecting rod 501 to move. The connecting rod 501 drives the pushing plate 502 and the sliding rod 503 to move along the sliding groove 504. When the pushing plate 502 and the sliding rod 503 slide to the end of the sliding groove 504, the sliding rod 503 moving along the lower track will collide with the guide block 506, and cause the guide block 506 to rotate and tilt through the rotating rod 505. When the sliding rod 503 passes over the guide block 506, the guide block 506 loses the acting force of the sliding rod 503 and resets by its own gravity. At this time, the reciprocating lead screw 401 drives the positive magnet block 402 to move to the end of the spiral groove of the reciprocating lead screw 401 and starts to move in the reverse direction. At this time, the sliding rod 503 moves in the reverse direction at the same time and moves upward along the top surface of the guide block 506 into the upper track, preventing the dust swept down from being pushed back into the quadrilateral tube 1 again, causing secondary pollution, and further maintaining the cleanliness of the square tube.
[0030] Embodiment 3
[0031] Please refer to Figures 1 - 6 As shown in the figure, the auxiliary mechanism 6 includes an expansion window 601, a rotating rod 602, a linkage plate 603, a mounting frame 604, and a touch plate 605. The rotating rod 602 is rotatably connected to the inner wall of the quadrilateral tube 1. The expansion window 601 is fixedly connected to the surface of the rotating rod 602. The linkage plate 603 is fixedly connected to the surface of the expansion window 601. The mounting frame 604 is fixedly connected to the front part of the square frame 404. The touch plate 605 is rotatably connected to the inner wall of the mounting frame 604. The linkage plate 603 is located on the movement track of the mounting frame 604. The square frame 404 drives the touch plate 605 on its surface to move. During the movement of the touch plate 605, it collides with the linkage plate 603, causing the linkage plate 603 to drive the expansion window 601 to rotate along the inner wall of the quadrilateral tube 1 and expand the ventilation area, so that the gas in the etching work can be accelerated to disperse through the pipeline. Quickly dispersing the etching gas can reduce the residual amount of the gas in the reaction area.
[0032] When the intake square pipe for etching of the present utility model is in use, after the operator installs the square pipe at the air inlet of the etching operation area, the motor 3 is started. The motor 3 drives the reciprocating lead screw 401 to rotate, causing the positive magnet block 402 on its surface to move reciprocally along the spiral groove on its surface. Under the magnetic attraction of the positive magnet block 402 and the negative magnet block 403, the negative magnet block 403 is driven to move reciprocally along the top wall of the quadrilateral pipe 1. The negative magnet block 403 drives the square frame 404 to move, and the square frame 404 drives the cleaning head 405 connected to its surface to reciprocally clean the inner wall of the quadrilateral pipe 1, so that some dust and dirt attached to the inner wall of the quadrilateral pipe 1 are swept down, keeping the inside of the intake square pipe clean. At the same time, the filter net 406 intercepts some impurities and dust carried in the air flow during intake, preventing dust and impurities from entering the etching working area through the square pipe and polluting the engraved object, thereby reducing the working quality and product quality. At the same time, the square frame 404 drives the connecting rod 501 to move, and the connecting rod 501 drives the push plate 502 and the sliding rod 503 to move along the sliding groove 504. When the push plate 502 and the sliding rod 503 reach the end of the sliding groove 504, the sliding rod 503 moving along the lower track will collide with the guide block 506, causing the guide block 506 to rotate and tilt through the rotating rod 505. When the sliding rod 503 passes over the guide block 506, the guide block 506 loses the acting force of the sliding rod 503 and resets by its own gravity. At this time, the reciprocating lead screw 401 drives the positive magnet block 402 to move to the end of the spiral groove of the reciprocating lead screw 401 and starts to move in the reverse direction. At this time, the sliding rod 503 also moves in the reverse direction and moves up along the top surface of the guide block 506 into the upper track, preventing the swept dust from being pushed back into the quadrilateral pipe 1 again, causing secondary pollution, further maintaining the cleanliness of the square pipe, reducing equipment failures and performance degradation caused by pipeline pollution, thereby reducing the frequency of maintenance and replacement of components, saving maintenance costs. Finally, after the etching work is completed, the square frame 404 drives the touch plate 605 on its surface to move. During the movement of the touch plate 605, it collides with the linkage plate 603, causing the linkage plate 603 to drive the expansion window 601 to rotate along the inner wall of the quadrilateral pipe 1 and expand the ventilation area, so that the gas in the etching work can be accelerated and dissipated through the pipeline. Quickly dissipating the etching gas can reduce the residual amount of gas in the reaction area, avoid adverse effects of the residual gas on subsequent process steps, and ensure the product quality and process stability.

Those of ordinary skill in the relevant technical fields can still make various changes and modifications without departing from the spirit and scope of the embodiments of the present utility model.
