Technical Field

[0001] The utility model belongs to the field of foam plastic products, and particularly relates to a cutting device for foam plastic products. Background Art

[0002] Foam plastics are a type of polymer material formed by a large number of gas micropores dispersed in solid plastics. Foam plastics have the characteristics of light weight, heat insulation, sound absorption, shock absorption, etc., and their dielectric properties are superior to those of the matrix resin, and they are widely used. Almost all plastics can be made into foam plastics, and foam molding has become an important field in plastic processing. Types include polystyrene foam plastics, PMI foam plastics, etc.

[0003] Currently, a Chinese utility model with the publication number of CN212241276U discloses a foam plastic cutting device, which includes a cutting table. Four columns are symmetrically and fixedly arranged on both sides of the bottom of the cutting table. One side of the front end of the cutting table is rotatably connected with a straight shaft. The same cutting frame is fixedly arranged at both ends of the top of the straight shaft. A cutting mechanism is arranged on the cutting frame. A protractor is fixedly arranged at the front end of the cutting table, and the protractor is arranged at the rear end of the cutting frame. An opening is formed on the cutting frame. One side of the cutting frame is rotatably connected with a support rod. A groove is formed at the front end of the cutting table. A slider is slidably connected in the groove. The other side of the support rod is rotatably connected with the slider. A plurality of uniformly distributed screw holes are formed in the groove. A knob is threadedly connected to the slider. In the utility model, a slider is provided. By moving the position of the slider in the groove, the support rod is driven to rotate, and the cutting frame is driven to rotate. After rotating to a predetermined position, the position of the slider is fixed by the cooperation of the knob and the screw hole, and the cutting mechanism is started for cutting, so as to facilitate cutting the bevel edge of the foam plastic.

[0004] During the use of this cutting device, when adjusting the cutting angle, it is necessary to support the cutting frame or the slider. After determining the angle of the cutting frame, the position of the slider is limited and fixed. This makes the adjustment inconvenient. At the same time, when the foam is fixed by the pressing plate, after the front section of the foam is cut, it is necessary to cancel the fixation of the foam by the pressing plate. After the foam is advanced to the cutting area, the foam is fixed again. Such operations are inconvenient and cumbersome. Summary of the Utility Model
