Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary equipment for laser processing, specifically a dust collection device for a laser engraving machine. Background Technology

[0002] Laser engraving machines are widely used in material processing, such as engraving letters and patterns on wood, plastic, and metal surfaces. However, laser cutting equipment mainly melts or vaporizes the material on the raw material through the high temperature of the laser. In this process, a large amount of powder is often generated, forming cutting dust. This dust must be collected, otherwise it will affect the engraving quality and may even damage the laser lens, increasing costs.

[0003] In existing technologies, the suction port of the dust collection device is usually set at a certain distance from the laser head and moves with it to ensure the dust collection effect. However, when the laser head is engraving the inner side of the arc-shaped plate, the suction port on the side is prone to interference with the concave surface, impacting the arc-shaped plate, causing damage, affecting the work process, and increasing costs. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a dust collection device for a laser engraving machine. This invention uses a rotating shell to drive the dust collection pipe to rotate. When engraving the inner surface of an arc-shaped plate, the dust collection pipe can be rotated to the side without upward bending, thus avoiding interference and damage, ensuring the work progress, and reducing costs.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a dust collection device for a laser engraving machine, including a laser head, a fixed body on the laser head, a dust collection pipe on one side of the laser head, a rotating shell on the fixed body, and a suction pump unit connected to the rotating shell through a pipe; the lower end of the dust collection pipe is provided with a dust collection port aligned with the laser head, and the upper end is provided with an exhaust port, which is connected to the rotating shell.

[0006] Preferably, the rotating shell includes two fixed ring plates with L-shaped cross-sections and a rotating ring plate with a grooved cross-section. The inner edge of the rotating ring plate is provided with a mounting plate. The rotating ring plate is driven to rotate by a driving unit. The two fixed ring plates with L-shaped cross-sections are arranged back to back on the fixed body. The rotating ring plate with a grooved cross-section is fastened to the two fixed ring plates. The mounting plate is rotatably connected to the fixed ring plates in a sealed manner.

[0007] Preferably, the fixed ring plate is connected to the pipeline, and the rotating ring plate is connected to the outlet of the suction pipe.

[0008] Preferably, the drive unit includes a drive motor, a gear ring located on the rotating ring plate, and a transmission shaft. One end of the transmission shaft is connected to the output end of the drive motor, and the other end is provided with a drive gear, which meshes with the gear ring.

[0009] Preferably, the pipeline is provided in multiple parts and is evenly connected to the fixed ring plate.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] (1) By setting a rotating shell to drive the vacuum tube to rotate, when carving the inner side of the arc-shaped plate, the vacuum tube can be rotated to the side that is not bent upwards, avoiding interference and damage, ensuring the work progress and reducing costs.

[0012] (2) The rotating shell includes two fixed ring plates with L-shaped cross sections and a rotating ring plate with a grooved cross section. The inner edge of the rotating ring plate is provided with a plate. The rotating ring plate is driven to rotate by a drive unit. The two fixed ring plates with L-shaped cross sections are arranged back to back on the fixed body. The rotating ring plate with a grooved cross section is fastened to the two fixed ring plates. The plate is sealed and rotated with the fixed ring plates, realizing the mutual rotation of the rotating ring plate and the fixed ring plate. While driving the dust suction pipe to rotate and change position, it also ensures the conveying of dust.

[0013] (3) Fix the ring plate to connect the pipe, and rotate the ring plate to connect the outlet of the suction pipe; the dust sucked in by the suction pipe enters the rotating shell and is then collected through the pipe.

[0014] (4) Multiple pipes are provided and evenly connected to the fixed ring plate to ensure that the dust coming out of the exhaust port can enter the pipe as soon as possible when the dust suction pipe rotates to any position. Attached Figure Description
