[0002] Embossed pattern aluminum plate is a kind of aluminum plate that is treated specially, and the pattern is pressed on the surface of the aluminum plate by mechanical action, giving it a unique visual effect. This aluminum plate not only has good decorative properties, but also has excellent weather resistance and corrosion resistance, so it is widely used in the fields of building decoration, interior design and industrial product manufacturing. The existing embossing device, such as the surface embossing device for plastic steel strip processing disclosed in Chinese Utility Model No. CN201922339850.5, includes multiple groups of rollers arranged on the rack at intervals along the processing metal strip, and the rollers are used for metal strip winding and embossing respectively. The defect of the above-mentioned device is that when the aluminum strip is stretched from the winding sleeve to the embossing device for embossing, the indentation is often shallow, that is, there is a certain gap between the rollers when the embossing roller is pressing the steel strip, and the middle position of the aluminum strip is suspended. With the conveying of the aluminum strip, the suspended part of the aluminum strip is prone to shaking up and down, which further causes the aluminum strip to shift when embossing, affecting the embossing precision of the aluminum strip.

[0014] The following is further described in detail through specific embodiments:

[0015] The reference signs in the drawings of the specification include: rack 1, embossing roller 2, centering support 3, transmission roller 4, drive motor 41, aluminum strip 5, roller 6, adjusting arm 7, spring 8, support rod 9, first sliding block 101, second sliding block 102, first limiting hole 11, second limiting hole 12.

[0016] The embodiment is substantially as shown in the accompanying Figure 1 to the accompanying Figure 2 drawings:

[0017] An aluminum strip automatic centering device includes a rack 1 and an embossing roller 2. The upper surface of the rack 1 is a desktop, which is divided into two sections. From left to right below the desktop, transmission rollers 4, the embossing roller 2, and transmission rollers 4 are installed along the transmission direction. A strip-shaped notch is opened on the desktop corresponding to the transmission rollers 4, which is used for the contact between the top surface of the transmission rollers 4 and the bottom surface of the aluminum strip 5 transmitted on the desktop.

[0018] The embossing roller 2 includes a roller with embossed patterns and a smooth roller. A centering assembly is suspended on the upper part of the embossing roller 2 by a support. The centering assembly includes a centering support 3, adjusting arms 7, and a compression wheel. The centering support 3 is a hollow square box. Two adjusting arms 7 are symmetrically installed on the two outer sides of the centering support 3, and there are a total of four adjusting arms 7. The vertical section of the adjusting arm 7 is in the shape of “L”. The aluminum strip 5 is lifted by the horizontal bottom surface of the adjusting arm 7 through the two opposite openings of the adjusting arm 7 on one side, and the aluminum strip 5 is limited from both sides by the vertical inner side wall of the adjusting arm 7.

[0019] The end of the adjusting arm 7 close to the centering support 3 is fixed with a first sliding block 101. A horizontal sliding groove is symmetrically opened on both sides of the centering support 3, and the opening of the sliding groove faces the outer side of the side wall of the centering support 3. The first sliding block 101 is slidingly connected in the sliding groove. A plurality of first limiting holes 11 are opened on the top of the sliding groove along the length of the sliding groove. The first limiting hole 11 includes a through hole penetrating the side wall of the sliding groove and a blind hole opening towards the through hole at the same position. The adjusting arm 7 can be limited between two first limiting holes 11 by a bolt passing through the through hole and the blind hole. The distance between adjacent first limiting holes 11 is the length of the first sliding block 101. Thus, the distance between the adjusting arms 7 can be freely adjusted according to the width of the aluminum strip 5 actually produced.

[0020] Further, to improve the efficiency of adjustment, a scale line is marked on the surface of the first limiting hole 11 of the first sliding block 101.

[0021] Two pressing wheels are symmetrically installed on the two outer sides of the centering support 3, and the total number of the pressing wheels is four, the pressing wheel comprises a supporting rod 9, a roller 6 and a spring 8. The middle axis of the roller 6 is fixed on the two ends of the supporting rod 9, the height of the supporting rod 9 is higher than the height of the adjusting arm 7, and the supporting rod 9 is in the shape of an arc strip downward. The roller 6 can rotate freely along the middle axis, and the end of the supporting rod 9 away from the roller 6 is hinged to the second sliding block 102. The spring 8 is fixed between the second sliding block 102 and the end of the supporting rod 9 close to the roller 6. A horizontal sliding groove is symmetrically arranged on the two sides of the centering support 3 and at a position higher than the first sliding block 101, the second sliding block 102 is slidably connected in the sliding groove, a plurality of second limiting holes 12 are arranged on the top of the sliding groove along the length of the sliding groove, the second limiting hole 12 also comprises a through hole and a blind hole facing the through hole, the second sliding block 102 can be limited between adjacent second limiting holes 12 by penetrating the through hole and the blind hole with a bolt, and the distance between adjacent second limiting holes 12 is the length of the second sliding block 102. Thus, the position of the whole pressing wheel on the side wall of the centering support 3 can be freely adjusted.

[0022] The specific implementation process is as follows:

[0023] In the production of the embossed aluminum strip 5, the transmission roller 4 is started by driving the motor 41, the transmission roller 4 drives the aluminum strip 5 to move towards the embossing roller 2, the aluminum strip 5 travels horizontally along the desktop in a state parallel to the ground, the aluminum strip 5 does not hang in the air, before the aluminum strip 5 enters the embossing roller 2, the adjusting arm 7 on the centering support 3 limits the two side walls of the aluminum strip 5 from both sides, so that the aluminum strip 5 can be transmitted into the gap between the two embossing rollers 2 perpendicularly to the embossing roller 2, before entering the gap, the circumferential side wall of the pressing wheel on the centering support 3 is in contact with the surface of the aluminum strip 5, with the travel of the aluminum strip 5, the pressing wheel rotates, and the pressing force is freely adjusted by the spring 8, so that the aluminum strip 5 is tightly attached to the surface of the desktop, further avoiding that a large area of the aluminum strip 5 hangs in the air when passing through the embossing roller 2, after the aluminum strip 5 stably enters the embossing roller 2, the aluminum strip 5 with the embossed pattern passes through the pressing wheel again, is pressed on the surface of the desktop, and is again subjected to the limiting action of the adjusting arm 7, and is transmitted to the rear along the adjusting arm 7.
