Description

Technical Field

[0001] This invention relates to the field of container surface decals, and in particular to a flat cap fixed decal paper machine. Background Technology

[0002] Various containers are often decorated with decals. These decals enhance the appearance of the containers or represent company names or trademarks. These are done by applying decorative paper to the container surface. The process begins with a machine systematically applying the decorative paper to the flat lid surface. However, the paper does not immediately solidify on the container surface because the adhesive is fluid. Therefore, the paper must be allowed to solidify before it can adhere tightly to the container surface. As the adhesive solidifies, it shrinks, and the paper also shrinks. This results in gaps between the paper and the container surface, making the paper uneven and failing to meet the required process specifications. Summary of the Invention

[0003] The purpose of this invention is to provide a flat cover fixed decal machine, which solves the problem of uneven decals after the adhesive has solidified.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: This invention provides a flat-cover fixed decal paper machine, including a power unit, a flattening unit, and a clamping unit.

[0007] Optionally, the power assembly further includes a pad, a positioning plate, and a folding plate. The folding plate is bent and disposed on the pad, with the bottom end of the folding plate higher than the top end of the slide plate. The pad is disposed outside the movement path of the slide plate. The motor is disposed on the positioning plate. A rotating shaft is rotatably disposed on the folding plate. The rotating shaft is connected to the drive end of the motor by a chain. The first end of the steering rod is connected to the rotating shaft.

[0009] Optionally, the leveling assembly further includes a pusher plate and a pressure head. The pusher plate is disposed at the drive end of the first cylinder, and the pressure head is disposed on the pusher plate. The pressure head is also rotatably connected to the rolling frame.

[0010] Furthermore, the grinding frame includes a first side plate, a second side plate, a first rotating rod, and a second rotating rod. The first side plate and the second side plate are rotatably arranged side by side on the sliding plate. The first rotating rod and the second rotating rod are arranged on the first side plate and the second side plate. The pressure head is rotatably connected to the first rotating rod, and the grinding wheel is rotatably arranged on the second rotating rod.

[0011] Furthermore, the flattening assembly also includes a first side rod and a second side rod, which are arranged side by side on the slide plate. The rolling frame also includes a central rod, with the first side plate and the second side plate arranged on the central rod. The central rod passes through the first side plate and the second side plate, and is rotatably arranged on the first side rod and the second side rod. The first side rod and the second side rod extend to the outer edge of the sliding side of the slide plate.

The first clamping groove and the second clamping groove are disposed opposite to each other.

[0014] Due to the application of the above-mentioned technical solution, the present invention has the following advantages compared with the prior art: The flat cover fixed decal applicator of the present invention uses a motor-driven steering rod to rotate circumferentially. The steering rod drives the sliding plate to move through the connecting rod. The sliding plate moves back and forth in a cycle, which in turn drives the roller to move back and forth. The roller then rolls the decal on the flat cover back and forth, causing the decal to slowly adhere to the flat cover. The decal is then flatly adhered to the flat cover, and there are no uneven areas on the decal, thus solving the problem of uneven decal after the adhesive has solidified.
