Technical Field
[0001] This utility model belongs to the field of grooving processing of advertising boards, and relates to a grooving machine for advertising decorative boards. Background Technology
[0002] In advertising production, grooving is often required to groove advertising panels according to installation or decoration needs. The purpose of grooving is generally to provide structural connection points for decorative panels; for example, aluminum composite panels can be locked to brackets through grooves, improving installation efficiency and stability. It can also facilitate concealed wiring or the embedding of other components, such as LED light strips, avoiding exposed wiring that affects aesthetics. With the development of machining, handheld grooving machines have become popular due to their flexibility and convenience. However, existing handheld grooving machines often adjust the groove depth by installing and replacing shims of different thicknesses to adjust the depth of the grooving drill bit inserted into the advertising panel. This adjustment method cannot achieve continuous and rapid adjustments within a certain range, and repeatedly requires tightening and loosening screws, resulting in poor flexibility.
[0003] Therefore, this utility model provides a grooving machine for advertising decorative panels, which solves the above problems. Utility Model Content

Connecting posts are fixedly installed at the front and rear of the upper right edge of the positioning ring, and auxiliary components are fitted on the connecting posts.
[0006] As a preferred embodiment of this utility model, both the fixing ring and the positioning ring are made of transparent acrylic sheet; by using transparent acrylic sheet, it is easy to observe the groove trajectory on the advertising decorative board.
[0007] In a preferred embodiment of this utility model, the adjusting ring is disposed on the upper edge of the fixed ring and is movably engaged under the front and rear protruding edges; this arrangement of the adjusting ring facilitates the prevention of loosening when rotating the adjusting ring and improves its stability in use.
[0008] In a preferred embodiment of this utility model, the auxiliary component includes a connecting plate. The left end of the connecting plate has insertion holes corresponding to the front and rear connecting columns, and the right end of the connecting plate has a hole for inserting upper and lower capped rotating shafts. A bushing is movably fitted on the rotating shaft. By using the auxiliary component, when it is necessary to use the straight edge of the plate for grooving, the bushing of the auxiliary component can be fitted with the straight edge of the plate, and the connecting plate can be fitted with the surface of the plate. By synchronously pushing the auxiliary component along the straight edge of the plate, the groove made by the grooving drill bit of the handheld grooving machine can be parallel to the straight edge of the plate.
[0009] As a preferred embodiment of this utility model, a recessed platform is formed on the lower left side of the connecting plate, and the lower sidewall of the connecting plate is flush with the lower surface of the positioning ring.
[0010] The beneficial effects of this utility model are as follows: By rotating the adjusting ring, the adjusting ring drives the front and rear gears to rotate in the same direction simultaneously through the internal teeth. Due to the effect of the front and rear U-shaped limiting grooves, the front and rear gears drive the front and rear lead screws to move up or down simultaneously, thereby driving the lower positioning ring to move down or up relative to the fixed ring. Thus, within a certain range, the length of the grooving drill bit passing through the positioning plate can be quickly adjusted, thereby quickly changing the grooving depth and improving the flexibility during use.
