Description

Technical Field

[0001] The utility model relates to the technical field of edge sealing of billboard production, in particular to an edge sealing device for a billboard. Background Art

[0002] When making billboards, the outer edges of the billboards need to be sealed. The existing billboard edge sealing grooves are manually held by hand to seal the edge strips, which is time-consuming and labor-intensive. In addition, the edges of the edge strips are sharp and easy to hurt hands, posing a safety hazard.

[0003] In order to solve the above technical problems, a Chinese utility model patent with publication number CN214410712U discloses an edge banding structure for billboard production, which relates to the field of edge banding technology for billboard production. The edge banding structure for billboard production inserts the edge strip into the inner cavity of the U-shaped strip, and the pulley presses the top of the edge strip into the inner cavity of the U-shaped strip, and reduces friction. The side wheels pre-extrude the two sides of the edge strip and make the sliding of the edge strip rolling friction, thereby reducing the friction of the movement of the device. The edge banding plate is set in an L shape, and the opposite sides of the two edge banding plates are both semicircular arcs. The screw head is rotated, and the screw rod rotates to push the edge banding plate to squeeze and clamp the edge of the edge strip, thereby completing the edge banding. The process only requires adjusting the position of the edge banding plate to adapt to edge strips of different specifications, and then inserting the edge strip into the inner cavity of the U-shaped strip, pulling the handle, and sliding the device. The operation is simple and convenient, and the edge banding efficiency is improved. In addition, since there is no need to hold the edge strip, the problem of sharp edges of the edge strip that are easy to hurt the hand is avoided.

[0004] However, most of the edge strips are "U"-shaped edging strips that have been bent into a fixed shape and do not need to be bent or pressed. The above structure is not applicable. In addition, during the edge sealing process of the "U"-shaped edging strips, it is necessary to pry the two sides of the edging strip apart while sealing the edge, which is inconvenient and reduces work efficiency. Some edging strips have inconsistent heights on both sides, and the existing edge sealing device cannot be adjusted, and is not suitable for edge sealing of edging strips with inconsistent heights on both sides. Utility Model Content

[0005] The utility model aims to provide an edge sealing device for billboards which can effectively improve the efficiency of edge sealing for billboards and is suitable for edge strips with inconsistent heights on both sides, thereby expanding the scope of application.

[0006] The utility model is achieved in this way:

[0007] A billboard edge sealing device comprises a U-shaped clamp, wherein one end of two vertical parts of the U-shaped clamp gradually approaches each other, a connecting groove is provided at the open end of the vertical part of the U-shaped clamp, adjustment holes are provided at both ends of the outer side of the connecting groove, an adjustment plate is inserted into the connecting groove, both ends of the adjustment plate close to the adjustment hole are elastically connected to limiting columns through springs, and the free end of the adjustment plate is fixedly connected to the guide groove.

[0008] Furthermore, a ball bearing is installed on the inner side wall of the guide groove.

[0009] Furthermore, a handle is fixedly connected to the top of the U-shaped clip.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The guide groove can be used to guide the edge strips on both sides of the billboard, and the U-shaped clip can be used to guide the edge strips on both sides. BRIEF DESCRIPTION OF THE DRAWINGS
