Description

Technical Field

[0001] The utility model relates to the technical field of advertising board processing equipment, in particular to a cutting device for advertising boards. Background Art

[0002] Advertising board materials are reflective printing materials whose visibility depends on the light emitted by passing vehicles reflecting back to the place where the light source is emitted. Vehicles and pedestrians in the same direction as the light source can clearly see the advertisement. It does not require other auxiliary light sources, so it does not consume energy while achieving visible effects. It is more environmentally friendly than lighted advertisements. After the advertising board is processed and formed, it needs to be cut by a cutting device to cut it into multiple small advertising boards. Most of the existing advertising board cutting devices do not have a positioning device. When cutting, the advertising board needs to be pressed and positioned manually. When positioning the advertising board in this way, the vibration generated during the cutting process may cause the position of the advertising board to shift, thereby affecting the cutting accuracy of the advertising board. Some are also equipped with a positioning device, and the positioning plate is driven by a separate positioning cylinder to position the advertising board. This method is costly.

[0010] After the above scheme is adopted, the advertisement board to be cut is placed on the cutting platform, and the rotating motor is started. The rotating motor drives the rotating screw to rotate through the transmission shaft. When the rotating screw rotates, it drives the slide to slide under the action of the thread. The slide drives the cutting arm to move synchronously. The cutting arm drives the cutting knife to slide toward the advertisement board. When the cutting arm moves, the pressing wheel is driven to move through the pressing arm. When the pressing wheel moves to the top of the protrusion through the guide surface, the protrusion drives the lifting plate to press the reset spring to move downward under the action of the pressing wheel. The lifting plate then drives the positioning plate to move downward and contact the advertisement board, thereby positioning the advertisement board. The cutting arm continues to drive the cutting knife to move, and the positioned advertisement board can be cut. After adopting the above scheme, the utility model has a reasonable structure and good use effect. BRIEF DESCRIPTION OF THE DRAWINGS
