During the laser cutting process of the small pack label paper, a large amount of dust is generated.

[0003] To ensure the normal operation of the laser cutting system, the current dust removal system absorbs dust through a flat-mouth hose. The space is open and the sealing is poor, which cannot effectively collect the dust generated during the cutting process. The dust removal effect is not ideal. The dust removal system needs to be cleaned 16 times a day, each cleaning takes 5 minutes, and the total cleaning time per day is 80 minutes.

[0023] like Figure 1-3 As shown, the dust removal device for laser cutting of cigarettes of the present invention is installed at the bottom of the laser cutting device for small box label paper of a lifting-type cigarette packaging device. The device includes a vortex chamber 22, a first dust suction port 21, a second dust suction port 11, and a negative pressure source (not shown in the figure). The negative pressure source, the first dust suction port 21, and the second dust suction port 11 are respectively connected to the vortex chamber 22. The negative pressure source generates negative pressure in the vortex chamber 22. The first dust suction port 21 and the second dust suction port 11 respectively draw airflow into the vortex chamber 22 from different directions, causing the drawn airflow to form a rotating airflow within the vortex chamber 22. Dust-laden gas enters through the dust suction port, and the structure is used to form a fluid pneumatic vortex airflow within the vortex chamber 22. The airflow forms a vortex motion while obtaining a rotational motion, which can effectively collect dust generated during the cutting process, thereby improving the dust removal effect.

[0024] In a specific embodiment, the cigarette laser cutting dust removal device includes a base 1 and a top cover 2 fixed on the base 1, a vortex chamber 22 is formed in the top cover 2, a first dust suction port 21 is provided on the top cover 2, and a second dust suction port 11 is provided on the base 1. The airflow inhaled on the top cover 2 and the airflow inhaled by the base 1 collide with each other, forming a vortex airflow in the vortex chamber 22, gathering dust and improving the dust removal effect. Preferably, the base 1 is provided with an air guide groove 12 respectively connected to the second dust suction port 11 and the vortex chamber 22, the base 1 is a plate-like structure, the second dust suction port 11 is horizontally arranged, and the airflow inhaled by the second dust suction port 11 changes its flow direction through the air guide groove 12 and enters the vortex chamber 22. One side wall of the air guide groove 12 is connected to the second dust suction port 11, and the other side wall forms an inclined air guide surface, so that the dust-laden airflow entering the vortex chamber 22 forms a vortex with the dust-laden airflow entering the first dust suction port 21. More specifically, the first dust suction port 21 is located at the top of the top cover 2, and the air guide groove 12 is located below the top cover 2, so that the upper and lower airflows collide to form a vortex.

[0025] The top cover 2 is provided with a negative pressure port, which is connected to the negative pressure source through the tapered tube 3. The negative pressure port is arranged on the side wall of the top cover 2 and communicates with the vortex chamber 22. Dust-laden gas enters tangentially from the inlet. The special structure of the dust removal device forms a fluid pneumatic vortex airflow. The airflow obtains rotational motion and forms a vortex motion at the same time, generating a strong vortex airflow for the dust. The dust is then introduced into the tapered tube 3 through the negative pressure port and merges with the internal airflow, thereby improving the dust removal effect.

[0026] This device is used to clean the dust generated during the laser cutting process, and the dust removal effect is good. Under the premise of meeting the use requirements of the laser cutting system, the dust removal device is cleaned from 16 times a day to 4 times a day, and each cleaning takes 5 minutes, saving 80 minutes of cleaning time per day. This solves the current situation of laser cutting system dust removal devices with unsatisfactory dust removal effect, high cleaning frequency, and great cleaning difficulty. Due to the good dust removal effect, simple structure, strong practicality and easy promotion of this device, it can be derived and promoted to dust removal devices of various equipment dust removal systems in the future, with extremely high promotion value and social benefits.

[0027] The above are only preferred embodiments of the present invention and are intended to be illustrative rather than restrictive. The structures and connection methods of the components of the present invention are subject to change, and any equivalent transformations and improvements based on the technical solution of the present invention should not be excluded from the scope of protection of the present invention.
