[0001] The utility model relates to the technical field of flat paper flinging machines, in particular to a dust removal device for flat paper flinging machines. Background Art

[0002] With the development of social economy and the advancement of science and technology, the social demand for flinging machines is increasing. Flipping machines are widely used in the printing and packaging industries, mainly for cutting papers of various specifications and thicknesses to meet various usage needs. Among them, for flat sheets of paper, flinging machines are devices that cut flat sheets of paper during the production process. After the flat sheets of paper are transported to the flinging machine by the feeding equipment, they are flattened and cut on the flinging machine. By controlling the rotation speed of the flinging knife and the moving speed of the flat sheets of paper, the effect of controlling the length of the flat sheets of paper is achieved.

[0003] However, during the long-term cutting process of flat-sheet paper products, the flinging machine easily causes a lot of paper dust and paper fibers to float in the air and then adhere to the surface of the paper. This creates some problems: on the one hand, dust such as paper dust and paper fibers easily cause environmental pollution and endanger the health of operators; on the other hand, dust attached to the surface of paper will affect the printing effect, cause customer complaints, and affect customer satisfaction with flat-sheet paper products. Utility Model Content

[0020] like Figure 1 As shown, the utility model is a dust removal device for a knife flinging machine, which is installed on a knife flinging machine 1 including a paper feeding mechanism 101, a knife flinging 102 and a conveyor belt 105. The paper feeding mechanism 101 is supported by a paper feeding bracket 104, and the knife flinging 102 is supported by a knife flinging bracket 103. The knife flinging machine 1 and its various components all adopt existing technologies, which will not be described in detail here.

[0021] like Figure 2 and Figure 5As shown, in a preferred embodiment, the dust removal device for the knife-throwing machine of the utility model includes a dust collector 2 provided with an exhaust pipe 201 located on one side of the knife-throwing machine 1, and the exhaust pipe 201 is connected to a dust suction pipe 3 fixedly connected to the paper feed bracket 104 and facing the paper cutting position. When the dust collector 2 is started, the dust suction pipe 3 can suck out the paper dust generated at the paper cutting position of the knife-throwing machine 102. Before use, it should be noted that the power of the dust collector 2 is adjusted so that the dust suction pipe 3 can suck out the paper dust while preventing the paper from being deflected by a large wind force. Of course, the dust suction pipe 3 is not limited to being installed on the paper feed bracket 104, and can also be installed on the upper part of the knife-throwing machine 1 by another bracket. The dust suction pipe 3 is provided with a plurality of dust suction ports 301 in an array facing the paper cutting position. Of course, the dust suction ports 301 can also be arranged in a staggered manner along the radial direction of the dust suction pipe 3. The dust suction ports 301 are in a trumpet-shaped structure, so that a larger area of ​​paper dust at the paper cutting position can be absorbed.

[0022] like Figure 3 and Figure 4 As shown, in a preferred embodiment, a detachable mounting component 4 is provided at the lower part of the swing knife support 103, and the mounting component 4 is rotatably connected with the first dust removal roller 5 and the second dust removal roller 6 which are fitted with the paper feeding of the swing knife machine 1.
