Abstract
Description
Technical Field
[0001] The utility model relates to the field of foam plastic processing, in particular to a cutting device used for foam plastic processing. Background Art
[0002] Foam plastics are a type of polymer material formed by a large number of gas micropores dispersed in solid plastics. Although foam plastics can withstand some pressure without significant discoloration, the surface formed when processed with knives and saws is often not smooth enough, and scissors cannot cut. Only very sharp blades can be used to cut and process small planes, while slightly larger planes and curved blades are incapable of doing so. Foam plastics have a characteristic that they are easily melted by heat and are poor conductors of heat, so thermal cutting is generally used to cut foam plastics.
[0003] The current cutting device used for foam plastic processing, as described in the patent with announcement number CN218614526U, includes an operating table and an electric heating wire. A horizontal moving mechanism is installed on the top of the operating table, a vertical moving mechanism is installed on the top of the sliding block of the horizontal moving mechanism, a fixed box is installed on the side of the sliding block of the vertical moving mechanism, a dirt removal mechanism is welded on the right side of the fixed box, a material baffle is arranged on the right side of the dirt removal mechanism, a dirt removal shovel is arranged inside the left end of the dirt removal mechanism, a collecting box is threadedly sleeved on the bottom of the dirt removal mechanism, a tensioning structure is arranged inside the fixed box, and a winding and unwinding structure is arranged at the bottom of the tensioning structure.
[0004] With regard to the above-mentioned related technologies, the inventor believes that the stepper motor on the left side drives the reel to rotate and reel, and the used part of the left end of the heating wire is reeled onto the reel. At the same time, the stepper motor on the right side drives the reel to rotate and unwind, and the unused part of the right end of the heating wire is released. When the heating wire moves to the left from the dirt removal mechanism, the dirt removal shovel inside the dirt removal mechanism is used to remove the lumps on the surface of the heating wire. In order to completely clean the cut part of the heating wire for the foam plastic, it is necessary to make the cut part of the heating wire for the foam plastic completely pass through the dirt removal mechanism. Therefore, a part of the heating wire is always wound on the reel, so that the heat of the heating wire wound on the reel when the heating wire is energized cannot be effectively utilized, thereby causing a waste of electricity.
