[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. 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 processed metal strip, and the rollers are used for metal strip winding and embossing respectively. The defect of the above-mentioned device is that the company will produce a variety of different width specifications of embossed aluminum strip to meet the needs of different customers, resulting in that the embossing roller is always set to the length that meets the maximum width specification. This leads to the fact that when producing narrower embossed aluminum strip, the aluminum strip only contacts the middle part of the embossing roller, and after a long processing time, the middle part of the embossing roller is larger than its two ends in the gap, which increases the deformation of the winding degree and further aggravates the shaking space of the embossed aluminum strip between the embossing rollers, affecting the embossing precision of the aluminum strip. SUMMARY

[0003] The utility model provides an aluminium strip embossing device to solve the problem that the middle part of the existing embossing roller deforms after a period of processing, the gap of the middle part of the embossing roller is larger than that of the two ends, and the embossing precision of the aluminum strip is affected.

[0004] To solve the above-mentioned problems, the technical scheme adopted by the utility model is as follows: an aluminium strip embossing device, comprising a rack and an embossing roller, the rack comprises a desktop and a sliding rail, the embossing roller is a light roller and is used for single-sided embossing, the desktop is parallel to the ground and is arranged on the front and rear sides of the embossing roller respectively, the sliding rail is parallel to the desktop and is located below the desktop, the sliding rail is symmetrically arranged at the two ends of the embossing roller, a sliding block is slidably connected to the sliding rail, a straightening roller is arranged between the opposite sliding blocks on the two sliding rails, the straightening roller can rotate along its axial direction, a strip-shaped notch is opened at one end of the desktop away from the embossing roller, and the circumferential wall of the straightening roller is tangent to the strip-shaped notch.

[0005] An adjustable-angle electromagnetic heating device is installed on the frame. The electromagnetic heating device includes an electromagnetic heating coil, which is arc-shaped and can be arranged parallel to a portion of the circumferential sidewall of the embossing roller.

[0006] The basic principle of this solution is as follows: During normal use, the straightening roller acts as a conveyor roller, driving the aluminum strip on the table. When straightening of the embossing roller is required, the straightening roller slides to both sides of the embossing roller via a slider and is fixed. The side wall of the straightening roller contacts the side wall of the embossing roller, and the two straightening rollers can apply force to the embossing roller from both sides. The deformed part in the middle of the embossing roller is heated by an electromagnetic heating device, and then the straightening roller is driven to rotate by a drive motor to crush and straighten the deformed part in the middle of the embossing roller. After the embossing roller cools down, the straightening roller is moved back under the strip groove on the table, and aluminum strip embossing production can be carried out again.

[0007] The beneficial effects of this solution are as follows: Because the company produces embossed aluminum strips of various widths to meet the needs of different customers, the existing embossing rollers are always set to the length required for the widest width. When producing narrower embossed aluminum strips, the strip only contacts the middle of the roller. Over time, this causes the gap between the middle and ends of the roller to widen due to the strip's stretching. The continuous rotation of the roller further increases the deflection deformation, exacerbating the vibration of the strip within the rollers and affecting the embossing accuracy. This solution addresses this by installing a straightening roller that serves as both a conveyor and a straightener. An electromagnetic heating device is used to heat the embossing rollers, and the position of the straightening roller is adjusted via a slider and guide rail. This allows the embossing rollers on existing machines to be straightened even when changing the rollers used for embossing patterns, ensuring the accuracy of aluminum strip embossing production.

[0008] Furthermore, the slide rail is provided with several blind holes with upward openings at intervals along its length, and the slider is provided with through holes at the four corners. By passing through the through holes and blind holes simultaneously with the limiting screw, the slider can be fixed below the strip groove or on both sides of the embossing roller.

[0009] Furthermore, the electromagnetic heating coil is fixed to the frame by a bracket, which is a four-axis bracket. The four-axis bracket can be an existing display bracket, and the position of the heating coil can be freely adjusted in multiple directions to ensure that the disturbed and deformed parts of the embossing roller are fully heated.

[0010] Furthermore, the central shaft end of the straightening roller is connected by a key to the output end of a drive motor, which is fixed on the slider and controls the rotation of the straightening roller.

[0011] Furthermore, there are four sliders.

[0012] Furthermore, the central shaft end of the embossing roller is connected by a key to the output end of a drive motor, which is fixed on the frame and controls the rotation of the embossing roller. BRIEF DESCRIPTION OF DRAWINGS

[0017] The embodiment is basically as shown in the accompanying drawings: Figs. 1-2

[0018] An aluminum strip embossing device, comprising a rack 1 and an embossing roller 4, the rack 1 comprises a desktop 2 and a slide rail 3, the rack 1 is arranged parallel to the ground, the desktop 2 is arranged on the top surface of the rack 1, the desktop 2 is symmetrically installed on the front and rear sides of the embossing roller 4 with the embossing roller 4 as the center, the desktop 2 is used for abutting and supporting the horizontal aluminum strip 12, a strip-shaped notch is formed at the end of the two desktops 2 away from the embossing roller 4, and the strip-shaped notch is parallel to the embossing roller 4.

[0019] The slide rail 3 is located below the desktop 2 and is symmetrically arranged along the two sides of the desktop 2, and the slide rail 3 is arranged parallel to the desktop 2 and the bottom surface. The sliding block 6 is slidably connected to the slide rail 3, the straightening roller 8 is arranged between the opposite sliding blocks 6 on the two slide rails 3, the output end of the driving motor 9 is key-connected to the end portion of the straightening roller 8, and the driving motor 9 is fixed to the sliding block 6. The embossing roller 4 and the straightening roller 8 are all light rollers, the embossing roller 4 is used for single-sided embossing, and in the prior art, a roller with a patterned outer wall is arranged parallel to the top of the embossing roller 4. Since the roller with the pattern needs to be replaced according to the pattern requirements of the product, the roller does not need to be straightened in the present scheme.

[0020] Through holes penetrating through the four corners of the sliding block 6 are symmetrically formed, and blind holes 7 opening upward are formed in the slide rail 3 at intervals along the length of the slide rail 3. By penetrating the limiting screw through the through hole and the blind hole 7, the sliding block 6 can be fixed on the slide rail 3.

[0021] ​An electromagnetic heating device with adjustable angle is fixed beside the slide rail 3 of the frame 1. Specifically, the electromagnetic heating device is an open induction heating coil 10. The coil of the electromagnetic heating device is in the shape of an arc of a rectangle, and the arc faces downward and is parallel to the circumferential wall of the embossing roller 4. The electromagnetic heating device is fixed on the frame 1 by a support 11. The support 11 is a four-axis frame 1, and the electromagnetic heating device can be positioned above the embossing roller 4 or parallel to the frame 1 by the support 11.

[0022] The specific implementation process is as follows:

[0023] As shown in Fig. 1 , when the embossing device is in normal use, the aluminum strip 12 is in contact with the desktop 2 of the frame 1. The driving motor 9 drives the straightening roller 8 to rotate. The aluminum strip 12 is in contact with the straightening roller 8 on the ground and is conveyed to the embossing roller 4 under the drive of the straightening roller 8. After the pattern is pressed by the embossing roller 4, the aluminum strip 12 moves forward and is in contact with another straightening roller 8. The aluminum strip 12 is conveyed forward under the drive of the straightening roller 8.

[0024] As shown in Fig. 2As shown, when the embossing roller 4 is straightened or the patterned roller needs to be replaced, the embossing roller 4 at the lower light roller position is unchanged, the limiting screw on the sliding block 6 of the two straightening rollers 8 is removed, so that the sliding block 6 can freely slide on the slide rail 3, and the two sliding blocks 6 are respectively slid towards the embossing roller 4, so that the side wall of the straightening roller 8 is in contact with the embossing roller 4, and the sliding block 6 is fixed on the rail through the limiting screw. Then move the electromagnetic heating device to the upper position of the deformed middle part of the embossing roller 4, so that the arc surface of the electromagnetic heating coil 10 is close to the side wall of the embossing roller 4, start the electromagnetic heating coil 10, and start the machine to make the embossing roller 4 rotate, the middle part of the embossing roller 4 is heated, and the two straightening rollers 8 on both sides are started to rotate, so that the straightening roller 8 continuously rolls the embossing roller 4 from both sides, and the middle part of the embossing roller 4 is straightened. After straightening, stop the electromagnetic heating device, so that the embossing roller 4 and the straightening roller 8 gradually cool down in the rotating state, and after cooling, the middle part of the embossing roller 4 is straightened, and then the straightening rollers 8 on both sides are slid back to the lower part of the table 2 through the sliding block 6. The straightening roller 8 continues to play the role of auxiliary transmission. If the embossing roller 4 has large degree of deformation, and cannot be fixed in the pre-set blind hole 7 through the limiting screw, first weld the sliding block 6 at the position closest to the embossing roller 4 through electric welding, and then preliminarily straighten the embossing roller 4 once, and then remove the welding point with a pneumatic chisel after the embossing roller 4 is cooled, and then move the sliding block 6 towards the embossing roller 4, and then fix the sliding block 6 in the blind hole 7 and straighten again. The above is only an embodiment of the present application, and the specific structure and characteristics of the scheme are not described in detail. It should be noted that for those skilled in the art, without departing from the structure of the present application, a number of modifications and improvements can be made, which should be regarded as the protection range of the present application.
