Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1-3 As shown, this utility model provides a technical solution: a riser feeding channel processing device with a riser cutting structure, including a ring conveyor 1 for conveying, a limiting mechanism 2 for limiting the workpiece on the pallet of the ring conveyor 1, and an absorption mechanism 3 for absorbing flue gas at the front of the ring conveyor 1.

[0029] The limiting mechanism 2 includes a support shell 201 bolted to the pallet of the annular conveyor 1 for support. A baffle 202 for blocking the workpiece is fixedly connected to the upper surface edge of the support shell 201. A support block 203 for supporting a threaded rod 204 is connected to the lower inner wall of the support shell 201. A threaded rod 204 for moving a T-shaped plate a205 is connected through a bearing in the support block 203. The threaded rod 204 is connected through a bearing to the rear part of the inner wall of the support shell 201. A T-shaped plate a205 for limiting the workpiece is threadedly connected to the threaded rod 204. The T-shaped plate a205 is slidably connected through and on the inner wall of the support shell 201.

[0030] Place the workpiece whose riser needs to be removed on the upper surface of the support shell 201, and rotate the threaded rod 204 with an electric wrench to drive the T-shaped plate a205 to slide, pressing the workpiece onto the baffle 202.

[0031] like Figure 3 As shown, a slide rod 206 for guiding the L-shaped toothed plate 207 is connected to one side of the inner wall of the support shell 201. The L-shaped toothed plate 207 for moving the T-shaped plate b208 is slidably connected to the slide rod 206. The T-shaped plate b208 for limiting the workpiece is connected above the L-shaped toothed plate 207. The T-shaped plate b208 passes through and is slidably connected to the inner wall of the support shell 201.

[0032] The L-shaped toothed plate 207 slides along the slide bar 206, bringing the T-shaped plate b208 into contact with the workpiece and limiting the workpiece.

[0033] like Figure 3 As shown, a gear 209 for moving the L-shaped toothed plate 207 is meshed on the L-shaped toothed plate 207. The gear 209 is rotatably connected to the lower inner wall of the support shell 201. A worm gear 210 for rotating the gear 209 is connected above the gear 209. The worm gear 210 is rotatably connected to the upper inner wall of the support shell 201. A worm 211 for rotating the worm gear 210 is meshed on one side of the worm gear 210. The worm 211 is rotatably connected to the upper inner wall of the support shell 201 through a support plate. The worm 211 is connected to the rear part of the inner wall of the support shell 201 through a bearing.

[0034] The worm gear 211 is rotated by an electric wrench, which drives the worm wheel 210 to rotate, thereby driving the gear 209 to rotate. This, in turn, causes the two sets of L-shaped toothed plates 207 to slide simultaneously along the corresponding slide rods 206, so that the T-shaped plate b208 limits the two sides of the workpiece.

[0035] like Figure 1 , Figure 4 and Figure 5As shown, the absorption mechanism 3 includes a square box 301 connected to the front of the annular conveyor 1 for mounting the perforated plate 302, and the inner wall of the square box 301 is connected to the perforated plate 302 for allowing air to pass through.

[0036] The front of the square box 301 is connected to a U-shaped plate 303 for supporting the electric push rod 304. Above the U-shaped plate 303 is the electric push rod 304 for driving the lifting bucket 305 to rise and fall. Above the electric push rod 304 is the lifting bucket 305 for air intake.

[0037] The cut riser falls above the hollow plate 302 for collection. The electric actuator 304 is activated to drive the hoisting bucket 305 to rise and fall. The position of the laser cutting machine 6 is adjusted according to the position of the riser.

[0038] like Figure 5 As shown, the inner wall of the hoisting bucket 305 is connected to the y electric slide rail 4 for moving the x electric slide rail 5. The slide of the y electric slide rail 4 is connected to the x electric slide rail 5 for moving the laser cutter 6. The slide of the x electric slide rail 5 is connected to the laser cutter 6 for cutting the riser.

[0039] During operation, the Y electric slide rail 4 drives the X electric slide rail 5 and the laser cutting machine 6 to move back and forth. The X electric slide rail 5 drives the laser cutting machine 6 to move to both sides. The position of the laser cutting machine 6 is adjusted according to the position of the riser to cut off the riser on the workpiece.

[0040] like Figure 1 and Figure 5 As shown, the front of the hoisting bucket 305 is connected to a corrugated hose 306 for gas transmission, the bottom of the corrugated hose 306 is connected to an outer box 307 for mounting parts, the outer box 307 is connected to the front of the U-shaped plate 303, and the rear of the outer box 307 is connected to a connecting pipe 308 for gas transmission, which is connected to the front of the square box 301.

[0041] During the cutting process, part of the fumes generated by the laser cutting machine 6 enter the outer box 307 through the corrugated hose 306 via the hoisting bucket 305, and part enters the square box 301 through the perforated plate 302.

[0042] like Figure 4 As shown, an activated carbon mesh 309 for purifying flue gas is slidably connected to the inner wall of the outer casing 307 via a U-shaped piece, and an exhaust fan 310 for extracting air is connected to the front of the outer casing 307.

[0043] An opening is provided at the front of the inner wall of the outer casing 307, which is connected to the air inlet of the exhaust fan 310. When the exhaust fan 310 is turned on, the air inside the outer casing 307 is discharged to form a negative pressure, which draws the air into the square box 301 and the hoisting bucket 305, and then into the outer casing 307. After the activated carbon mesh 309 absorbs the harmful substances, the air is discharged through the exhaust fan 310. A sealed door is provided at the front of the outer casing 307. The activated carbon mesh 309 can be pulled out and replaced by opening the sealed door.

[0044] In summary: When using this utility model, firstly, by rotating the threaded rod 204 and worm gear 211 with an electric wrench, the positions of T-shaped plates a205 and b208 are adjusted. The workpiece whose riser needs to be removed is placed in the space enclosed by the baffle 202, T-shaped plates a205 and b208. Then, the z-electric push rod 304, x-electric slide rail 5 and y-electric slide rail 4 are activated to adjust the position of the laser cutting machine 6. Then, the exhaust fan 310 is activated to move the workpiece whose riser needs to be removed between the square box 301 and the lifting bucket 305. The laser cutting machine 6 emits a laser, and at the same time, the x-electric slide rail 5 moves to remove the riser on the workpiece. The cut riser falls onto the hollow plate 302, and the flue gas is drawn into the square box 301 and the lifting bucket 305. After being treated by the activated carbon mesh 309, the harmful substances are discharged through the exhaust fan 310. The contents not described in detail in this description belong to the prior art known to those skilled in the art.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
