[0002] A refractive embossing machine is an environmentally friendly device used to create special patterns on packaging materials. It works by wrapping a refractive embossing plate with a three-dimensional texture onto the plate mounting cylinder of the machine, and then working with the feed roller to emboss the gold and silver cardboard made of aluminum foil. This gives the embossed gold and silver cardboard a strong refractive effect, making it look luxurious and eye-catching, and enhancing its appearance.

[0039] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0040] Example 1

[0041] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0042] like Figures 1-2As shown, this application provides a packaging aluminum foil folding and embossing device, including an embossing machine body 1. The embossing machine body 1 mainly consists of a frame part, an embossing part, and a control part. The frame part is composed of stainless steel square tubes and sheet metal panels. The control part is mainly a PLC control system, which is fixedly installed inside the frame. The embossing part mainly consists of a feeding roller 2, a mounting roller, and an embossing plate 12 installed on the mounting roller. During operation, both the feeding roller 2 and the mounting roller are controlled to rotate by a motor. The surface of the feeding roller 2 is made of rubber and is mainly responsible for gripping the paper. The pressure between the feeding roller 2 and the embossing plate 12 on the mounting roller is used to imprint the pattern onto the aluminum foil.

[0043] However, during high-intensity embossing operations, the wear on the embossing plate 12 increases with working time, necessitating appropriate downtime for rest to reduce fatigue and wear caused by continuous operation. To avoid impacting production efficiency and extend the service life of the embossing plate 12, the mounting roller has been improved, with the following improved structure:

[0044] A drive unit 3 is fixedly installed on the main body 1 of the embossing machine. The drive unit 3 is connected to the PLC control system. The drive unit 3 is a servo motor. A transmission shaft 4 is connected to the bearing on the main body 1 of the embossing machine. One end of the transmission shaft 4 is fixedly connected to the output end of the drive unit 3. The drive unit 3 is controlled to rotate by the PLC control system, thereby driving the transmission shaft 4 to rotate, and thus cooperating with the feed roller 2 to rotate.

[0045] like Figures 2-3 As shown, the middle part of the transmission shaft 4 is milled into two symmetrical planes on both sides by a milling machine. These planes are set as guide planes. A switching block 5 is set in the axial direction of the transmission shaft 4. A sliding groove 6 is opened on the inner side of the switching block 5. The transmission shaft 4 is located in the sliding groove 6. Its guide plane cooperates with the sliding groove 6, thereby restricting the circumferential position of the switching block 5 and the transmission shaft 4. When the transmission shaft 4 rotates, it will drive the switching block 5 to rotate synchronously.

[0046] The sliding groove 6 is perpendicular to the axis of the drive shaft 4. By sliding the drive shaft 4 in the sliding groove 6, the two ends of the switching block 5 can move closer to or further away from the axis of the drive shaft 4.

[0047] A control unit is fixedly installed on the guide plane of the drive shaft 4. The control unit is a double-acting cylinder 10. The two ends of the cylinder shaft of the double-acting cylinder 10 are fixedly connected to the two sides of the sliding direction of the switching block 5. The double-acting cylinder 10 is connected to the PLC control system. The PLC control system is equipped with a solenoid valve and an air source. The air source supplies air to the double-acting cylinder 10. The solenoid valve controls the double-acting cylinder 10 to move in opposite directions. The air pressure in the double-acting cylinder 10 can be controlled by adjusting the size of the air source. Under the control of the solenoid valve, the double-acting cylinder 10 can drive the switching block 5 to slide along the direction of the sliding groove 6. The switching block 5 stops when it contacts the end of the sliding groove 6, so that the switching block 5 has two sliding limit positions on the drive shaft 4.

[0048] When the switching block 5 slides to its limit position, one side of the switching block 5 will be close to the axis of the drive shaft 4, while the other side of the switching block 5 will be far away from the axis of the drive shaft 4.

[0049] Both sides of the sliding direction of the switching block 5 are fixedly installed with abutment blocks 7. The abutment blocks 7 are arc-shaped tile structures and are made of stainless steel, which has high hardness.

[0050] like Figures 2-4 As shown, mounting blocks 11 are fixedly installed on both guide planes of the drive shaft 4. Two sets of mounting components are movably connected to the drive shaft 4. An embossed plate 12 is installed on the side of the mounting component away from the drive shaft 4. The mounting component includes two sets of fixing plates 9 connected to the mounting blocks 11 by bearings. The ends of the two sets of fixing plates 9 away from the drive shaft 4 are fixedly connected to the embossed plate 12. The two sets of fixing plates 9 are located inside the abutment block 7, while the two sets of embossed plates 12 are located outside the abutment block 7.

[0051] Meanwhile, the other ends of the two sets of embossed plates 12 are fixed to the fixing plates 9 on another set of mounting components, so that the embossed plates 12 can be wrapped around the outside of the abutting block 7 when they come into contact with the abutting block 7 under the pull of the two sets of fixing plates 9.

[0052] When the switching block 5 slides to one extreme position under the control of the double-acting cylinder 10, the abutment block 7, which is away from the axis of the transmission shaft 4, will squeeze the embossed plate 12 to move outward. The embossed plate 12 bends and deforms under pressure and partially adheres to the outer arc surface of the abutment block 7.

[0053] When the switching block 5 slides to the limit position, the distance between the connection point of the fixed plate 9 and the embossing plate 12 and the axis of the drive shaft 4 is less than the distance between the outer surface of the abutting block 7 and the axis of the drive shaft 4. Therefore, the embossing plate 12 will be tightly attached to the outer arc surface of the abutting block 7. The curvature of the outer surface of the embossing plate 12 is consistent with the curvature of the mounting roller where the embossing plate 12 is installed. The distance between the outer surface of the embossing plate 12 and the axis of the drive shaft 4 is also equal to the outer diameter of the mounting roller where the embossing plate 12 is installed. That is, the embossing plate 12 has reached the embossing station.

[0054] At this time, the drive unit 3 controls the transmission shaft 4 to rotate, which can drive the extruded and deformed embossing plate 12 to rotate, thereby cooperating with the feed roller 2 to perform refracting and embossing operations on the aluminum foil paper;

[0055] A groove 8 is provided on the outer side of the abutment block 7. A protrusion 14 that matches the groove 8 is fixedly installed on the side of the embossed plate 12 near the abutment block 7. This allows the circumferential position of the embossed plate 12 to be restricted by the cooperation of the groove 8 and the protrusion 14 when the embossed plate 12 is pressed and adhered to the surface of the abutment block 7, so as to prevent the embossing process from shifting and affecting the embossing effect.

[0056] An encoder is installed on the main body 1 of the embossing machine. The encoder is fixedly connected to the output end of the transmission shaft 4 and is connected to the PLC control system. The encoder can record the number of rotations of the embossing plate 12 that is performing embossing operations, i.e., the number of embossing operations. By setting the number of switching operations of the embossing plate 12 in the PLC control system, when the encoder detects that the number of rotations has reached the set number of switching operations, the PLC control system will automatically control the double-acting cylinder 10 to perform a reversing action, so that the switching block 5 slides to another extreme position. The embossing plate 12 that was previously performing embossing operations will lose the pressing force of the abutment block 7, and the other embossing plate 12 will adhere to the surface of the abutment block 7 in the pressing direction of the abutment block 7 on the same side and reach the embossing station to perform embossing operations.

[0057] By repeatedly using the embossing plate 12 alternately, the fatigue accumulation of the embossing plate 12 during long-term embossing operations can be greatly reduced, thereby extending the service life of the embossing plate 12.

[0058] A coil spring 13 is installed between the two sets of fixed plates 9 and the mounting block 11 on the drive shaft 4. The coil spring 13 is used to give the fixed plate 9 a force to rotate towards the side of the abutment block 7. When the embossed plate 12 is pressed by the abutment block 7 on one side of the embossing station, the fixed plates 9 on both sides of the abutment block 7 will shrink towards the middle of the abutment block 7 under the action of the coil spring 13, thereby improving the stability of the embossed plate 12 and the abutment block 7 surface adhesion.

[0059] The abutment block 7 on the opposite side of the embossing station is at its limit position close to the axis of the drive shaft 4. The abutment block 7 will squeeze the fixed plate 9 on both sides of the same side to expand it outward. The embossing plate 12 will be straightened and flattened from its bent state. The elastic force of the coil spring 13 on the fixed plate 9 and the squeezing force of the abutment block 7 will fix the position of the fixed plate 9 and keep the embossing plate 12 in a flattened state. The flattened state of the embossing plate 12 is conducive to the storage and fatigue recovery of the embossing plate 12. Moreover, the flattened embossing plate 12 does not exceed the rotation range of the embossing plate 12 at the embossing station, so it will not affect the embossing.

[0060] The abutment block 7 has rounded chamfers on both sides of its circumference, so that when the embossed plate 12 is pressed by the abutment block 7, the side edges of the abutment block 7 will not cause pressure damage to the surface of the embossed plate 12.

[0073] The encoder calculates the number of times the embossed plate 12 works and transmits the data to the PLC control system.

[0074] Set the switching frequency of embossed plate 12 in the PLC control system;

[0075] When the encoder detects that the switching count has been reached, the PLC control system controls the switching block 5 to slide to its limit in the opposite direction through the control unit.
