Description

Technical Field

[0001] The utility model relates to the field of industrial waste treatment equipment, in particular to a universal mechanical suction arm. Background Art

[0002] Suction arms are used to collect waste gases emitted at the source. They are suitable for collecting welding smoke, exhaust gas, dust, oil mist, and other waste gases generated by various industries such as machinery, food, pharmaceuticals, chemicals, electronics, and automobiles. Suction arms can hover at any position in three-dimensional space and be placed at the front end of engineering systems. Suction arms generally include mini suction arms, flexible suction arms, and universal suction arms.

[0003] The size of the opening at the suction end of the existing mechanical suction arm is generally fixed. When absorbing some small sticky wastes, such as moist sticky dust or dust with oil smoke, the suction arm cannot continue to increase the suction force at the suction arm port except for increasing the suction force through the power of the pump. Therefore, when absorbing and collecting some small sticky wastes, a greater suction force is required to absorb the small sticky waste more quickly. For this purpose, a universal mechanical suction arm is needed to adjust the size of the opening at the suction end of the suction arm to increase the flow rate of the airflow, thereby increasing the suction force on small sticky wastes. Utility Model Content

[0004] The utility model aims to overcome the defect that the size of the suction end opening is difficult to adjust and provides a universal mechanical suction arm.

[0005] The technical solution for achieving the above object is: a universal mechanical suction arm, comprising a suction arm main body, wherein the output end of the suction arm main body is connected to a suction pipe, characterized in that an extension pipe is connected to the side wall of the port of the suction pipe, an adjustment mechanism is connected to the side wall of the suction pipe, a moving mechanism is installed on the adjustment mechanism, and a connecting drive mechanism is installed on the adjustment mechanism;

[0006] The adjustment mechanism includes a connecting plate, a support rod, a guide rod, a baffle and a sliding hole. The side wall of the connecting plate is connected to two symmetrically distributed support rods, the side walls of the support rods are connected to the guide rods, and the side walls of the two symmetrically distributed baffles are provided with sliding holes. The side walls of the sliding holes are slidably connected to the guide rods, and the side walls of the baffles are in contact with the side walls of the extension tube.

[0007] Preferably, the shield is T-shaped.

[0008] Preferably, the side wall of the shield is connected to a guide plate.

[0009] Preferably, the moving mechanism includes a support plate, a round rod, a screw, a screw hole and a round hole. Round holes are opened at both ends of the side wall of the connecting plate. The round hole is slidably connected with a round rod, and the screw hole is threadedly connected with a screw. The side wall of the shield is connected to the support plate, and the side wall of the support plate is connected to the round rod, and one of the side walls of the support plate is rotatably connected with a screw.

[0010] Preferably, the support plate is T-shaped.

[0011] Preferably, the driving mechanism includes a rotating rod, a gear and a rack, the side walls of the two shields are connected to the rack, the rotation of the connecting plate is connected to the rotating rod, one end of the rotating rod is connected to the gear, and the side wall of the gear is engaged with the rack.

[0012] Preferably, the two racks are staggered on both sides of the gear.

[0013] Preferably, one of the racks is in the shape of a straight rod, and the other rack is in the shape of an L-shape.

[0014] The beneficial effects of the utility model are:

[0015] 1) The suction arm body absorbs the suction pipe and absorbs external substances through the extension pipe. The moving mechanism and the driving mechanism are used to synchronously move the two shields inward or outward. The two shields move inward, that is, the shield increases the area of the open end of the extension pipe blocked. Conversely, the shield reduces the area of the open end of the extension pipe blocked, thereby adjusting the shielding area of the extension pipe port. The extension pipe and the suction pipe are connected and communicated. Therefore, the extension pipe and the suction pipe are a whole. Therefore, the opening area of the extension pipe is reduced to increase the suction of the extension pipe, thereby improving the adsorption strength of adhered substances.

[0016] 2) Rotate the screw. The rotation connection between the screw and one of the support plates is self-rotation, that is, the screw rotates but the support plate does not rotate accordingly. The rotation of the screw will drive one of the support plates to move, and one of the support plates will drive one of the shielding plates to move, and one of the shielding plates will drive one of the racks to move, and one of the racks will drive the gear to rotate, and the gear will drive the other rack to move in the opposite direction, thereby driving the other shielding plate to move in the opposite direction, so that the two shielding plates can simultaneously increase or decrease the shielding area of the open end of the extension tube.

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] Reference Attachment Figure 1-5 A universal mechanical suction arm includes a suction arm body 1, an output end of the suction arm body 1 is connected to a suction pipe 2, a port side wall of the suction pipe 2 is connected to an extension pipe 7, a side wall of the suction pipe 2 is connected to an adjustment mechanism 3, a moving mechanism 4 is installed on the adjustment mechanism 3, and a connecting drive mechanism 5 is installed on the adjustment mechanism 3;

[0027] The adjustment mechanism 3 includes a connecting plate 301, a support rod 302, a guide rod 303, a baffle 304 and a sliding hole 305. The side wall of the connecting plate 301 is connected to two symmetrically distributed support rods 302, and the side wall of the support rod 302 is connected to the guide rod 303. The side walls of the two symmetrically distributed baffles 304 are provided with sliding holes 305. The side walls of the sliding holes 305 are slidably connected to the guide rod 303. The side walls of the baffle 304 are in contact with the side walls of the extension tube 7. The baffle 304 is T-shaped. The side walls of the baffle 304 are connected to the guide plate 6. The inclined surface of the guide plate 6 can guide the material to move toward the extension tube 7.

[0028] The suction arm main body 1 absorbs the suction pipe 2 by suction, and absorbs external substances through the extension pipe 7, and uses the moving mechanism 4 and the driving mechanism 5 to synchronously move the two baffles 304 toward the inside or outside. The two baffles 304 move toward the inside, that is, the baffle 304 increases the area of the open end of the extension pipe 7. Conversely, the baffle 304 reduces the area of the open end of the extension pipe 7, thereby adjusting the blocking area of the baffle 304 for the port of the extension pipe 7, and the extension pipe 7 and the suction pipe 2 are connected and communicated. Therefore, the extension pipe 7 and the suction pipe 2 are a whole, and therefore, the opening area of the extension pipe 7 is reduced to increase the suction of the extension pipe 7, thereby improving the adsorption strength of the adhered substances.

[0029] Reference Attachment Figure 2-5 The moving mechanism 4 includes a support plate 401, a round rod 402, a screw 403, a screw hole 404 and a round hole 405. Round holes 405 are provided at both ends of the side wall of the connecting plate 301. The round rod 402 is slidably connected in the round hole 405. The screw 403 is threadedly connected in the screw hole 404. The side wall of the shielding plate 304 is connected to the support plate 401. The side wall of the support plate 401 is connected to the round rod 402. One of the side walls of the support plate 401 is rotatably connected to the screw 403. The shape of the support plate 401 The T-shaped driving mechanism 5 includes a rotating rod 501, a gear 502 and a rack 503. The side walls of the two shielding plates 304 are connected to the rack 503. The rotation of the connecting plate 301 is connected to the rotating rod 501. One end of the rotating rod 501 is connected to the gear 502. The side wall of the gear 502 is engaged with the rack 503. The two racks 503 are staggered on both sides of the gear 502. One of the racks 503 is in the shape of a straight rod, and the other rack 503 is in the shape of an L.

[0030] When the screw 403 is rotated, the rotation connection between the screw 403 and one of the support plates 401 is self-rotating, that is, the screw 403 rotates while the support plate 401 does not rotate accordingly. The rotation of the screw 403 will drive one of the support plates 401 to move, and one of the support plates 401 will drive one of the baffles 304 to move, and one of the baffles 304 will drive one of the racks 503 to move, and one of the racks 503 will drive the gear 502 to rotate, and the gear 502 will drive the other rack 503 to move in the opposite direction, thereby driving the other baffle 304 to move in the opposite direction, so that the two baffles 304 can simultaneously increase or decrease the blocking area of the open end of the extension tube 7, and the guide rod 303 is used to limit the movement of the baffle 304, and the baffle 304 slides along the guide rod 303 through the sliding hole 305, and the round rod 402 slides along the round hole 405, and the guide rod 303 and the round rod 402 are placed in parallel to avoid the movement and deviation of the baffle 304.
