Detailed Description

The technical solution of the present invention is further explained with reference to the drawings and the embodiments.

As shown in fig. 1 to 3, in order to improve the service life of the dust removing device, an embodiment of the utility model provides a dust removing device of an engraving machine, which includes a dust collecting assembly fixedly mounted on a gantry of a machine tool, a dust collecting elbow 20 fixedly mounted on a head of the engraving machine, and an air suction pipe 10 fixedly mounted on the gantry of the machine tool, wherein the top of the air suction pipe 10 is provided with an air suction groove 15, the top of the air suction groove 15 is sealed by a sealing strip 18, a plurality of support rods 17 slidably mounted in the air suction groove 15 are uniformly fixed on the sealing strip 18, the dust collecting assembly is fixedly connected with and seals one end of the air suction pipe 10, the top of the dust collecting elbow 20 is slidably mounted on the inner top of the air suction groove 15, the side wall of the dust collecting elbow 20 far away from the dust collecting assembly is fixedly connected with a sealing plate 21 at the other end of the sliding sealing air suction groove 15, and two ends of the sealing strip 18 are respectively fixed on the side walls of the dust collecting assembly and the dust collecting elbow 20.

The dust collection assembly comprises a dust collection box 11 fixedly arranged at one end of the air suction pipe 10 and a fan 12 fixedly arranged at the top of the dust collection box 11, and a dust collection bag is fixedly arranged in the dust collection box 11; the top end of the dust collection bent pipe 20 is slidably arranged in the air suction groove 15, and the bottom end of the dust collection bent pipe 20 is fixedly connected to the head of the engraving machine and used for absorbing dust generated by engraving; when the dust suction elbow 20 is farthest away from the dust suction assembly, the sealing strip 18 is in a stretched state, the sealing strip 18 is horizontal, the sealing strip 18 seals the air suction groove 15, when the dust suction elbow 20 moves towards the dust suction assembly, due to the self-weight of the sealing strip 18 between the two adjacent support rods 17 and the fact that the air flow rate of the air suction groove 15 is larger than the air flow rate above the sealing strip 18, air pressure above the sealing strip 18 is larger than air pressure below the sealing strip 18, the sealing strip 18 receives downward force, the sealing strip 18 finally protrudes downwards, the sealing strip 18 is still located in the air suction groove 15 at the moment, and therefore the sealing strip 18 can still seal the section, between the dust suction elbow 20 and the dust suction groove 15, of the dust suction assembly in the process of machining and moving of the engraving machine head.

As shown in fig. 1-3, in order to prevent the sealing strip 18 from protruding downward to block the air suction groove 15, the strip-shaped protrusions 13 are fixedly arranged on the top of two side walls of the air suction groove 15, the support rods 17 slide between two strip-shaped protrusions 13, the width of the sealing strip 18 is equal to the distance between two strip-shaped protrusions 13, and two times of the distance from each support rod 17 to the bottom surface of each strip-shaped protrusion 13 is greater than the maximum distance between two adjacent support rods 17.

The top surface of the strip-shaped bulge 13 can be arranged to be higher than the top surface of the air suction pipe 10, so that the maximum distance of the sealing strip 18 protruding downwards can be increased, the number of the supporting rods 17 can be reduced, meanwhile, the width of the sealing strip 18 can be reduced due to the arrangement of the strip-shaped bulge 13, and the cost is saved; in the process of downward bulging of the sealing tape 18, the lowest position of the sealing tape 18 is in a state that the sealing tape 18 is folded in half, and when the sealing tape 18 is still on the bottom surface of the strip-shaped bulge 13 in the folded-in state, the sealing tape 18 can always seal the top of the suction groove 15, and meanwhile, the space of the suction groove 15 below the strip-shaped bulge 13 cannot be blocked by the sealing tape 18.

The top of the opposite side surfaces of the two strip-shaped bulges 13 is provided with a sliding groove 16, and the two ends of the supporting rod 17 are respectively arranged in the two sliding grooves 16 in a sliding way.

In a preferred embodiment, in order to improve the sealing performance of the suction slot 15, the nozzle at the top end of the dust collection elbow 20 is rectangular, and the outer wall of the dust collection elbow 20 is attached to the opposite side surfaces of the two strip-shaped protrusions 13.

As shown in fig. 2, in order to realize tight connection between the sealing strip 18 and the dust collection elbow 20 and the dust collection assembly, the suction groove 15 is fixedly provided with a connecting block 14 near the inner top of one end of the dust collection assembly, the supporting rod 17 at one end of the sealing strip 18 is fixedly connected to the connecting block 14, and the supporting rod 17 at the other end of the sealing strip 18 is fixedly connected to the dust collection elbow 20; the air inlet pipe of the dust collection box 11 is clamped between the connecting block 14 and the air suction groove 15, and is fixedly connected to the dust collection elbow 20 and the dust collection assembly through the supporting rods 17 at the two ends of the sealing belt 18, so that the sealing belt 18 is always tightly connected with the dust collection elbow 20 and the dust collection assembly.

In a preferred embodiment, in order to prevent dust with poor flowability from staying in the air suction groove 15, the air suction pipe 10 is obliquely and fixedly installed on a machine tool gantry, and one end of the dust suction assembly connected with the air suction pipe 10 is a low end; the dust falling in the suction slot 15 cannot stay on the bottom surface of the suction slot 15 due to the angle of the suction slot 15 and the suction force of the dust collection assembly, thereby preventing the suction slot 15 from being blocked.

Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
