Description

Technical Field

[0001] This invention relates to the field of hot stamping roller engraving technology, specifically to a precision engraving machine for hot stamping rollers used in cigarette tipping paper. Background Technology

[0002] Cigarette tipping paper, as a type of cigarette packaging printing material, serves as a fundamental carrier of the cultural connotations of cigarette products. Decorative graphic designs on cigarette tipping paper create aesthetic value and form a distinctive packaging style. Hot stamping can be used to print the desired trademarks and patterns on cigarette tipping paper, thereby enhancing its grade.

[0003] In the prior art, the publication number "202111126736X" relates to the field of intelligent engraving machines, specifically to an electromechanical integrated gravure electronic intelligent engraving machine, which includes an engraving device, an adjustment device, and a machine housing, wherein the adjustment device and the engraving device are both located inside the machine housing; however, this engraving device has problems such as low engraving efficiency and poor engraving effect.

[0004] Publication No. "201610613945X" discloses an engraving processing device for printing rollers, including a base plate, with support columns symmetrically arranged on both sides of the top of the base plate, and a laser engraving machine, a chrome plating box, and a polishing machine arranged sequentially from left to right on the top of the base plate and between the support columns; the engraving device is difficult to clean and has low cleaning efficiency.

[0005] In the existing technology, during the fine engraving process of hot stamping rollers, the engraving knife will carry out fine engraving along the pattern initially engraved. As the fine engraving continues, the debris generated during the fine engraving process will fall into the engraving marks produced by the rough engraving. Due to the variation in the pattern, the engraving marks have different depths. The engraving debris accumulated in the shallow engraving marks is less and easier to clean, but the debris remaining in the deep engraving marks is difficult to clean, and it is impossible to make the debris fall off and clean it by rotating the hot stamping roller. The debris and impurities remaining in the pattern engraving marks on the surface of the hot stamping roller will affect the engraving accuracy of the deep fine engraving pattern and affect the processing effect of the hot stamping roller.

[0006] Meanwhile, in the existing technology, before engraving the hot stamping roller, it is impossible for the operator's eyes alone to quickly and efficiently squeeze and fix the two sides of the hot stamping roller's central axis to the positioning component, which makes the clamping operation difficult and the clamping and positioning accuracy of the hot stamping roller low.

[0007] When the diameter of the hot stamping roller is different, the support and positioning angle required for clamping and fixing the hot stamping roller is different. However, the existing technology lacks the ability to adjust the positioning support according to the different diameters of the hot stamping roller, thereby reducing the clamping and fixing accuracy and efficiency of the hot stamping roller.

[0008] After the engraving of the hot stamping roller is completed, its outer surface needs to be cleaned. However, when the diameter of the hot stamping roller changes, the existing technology cannot adjust the corresponding cleaning effect of hot stamping rollers with different diameters, thereby reducing the cleaning effect of the hot stamping roller's vibration.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention.

[0039] Example 1

[0040] Please see Figure 1-9 The present invention provides a technical solution: a precision engraving machine for hot stamping rollers of cigarette tipping paper, comprising a frame 1, a robotic arm 2, an electrically controlled telescopic plate 3, a support unit and a peeling component. The support component supports the hot stamping roller, and the peeling component improves the cleaning effect of the hot stamping roller.

[0041] The top of the frame 1 is provided with a groove 11, the inside of which is a through groove 12, and the inside of the through groove 12 is provided with a horizontal column 13. Vertical columns 14 are provided on both sides of the horizontal column 13. The electrically controlled telescopic plate 3 is movably set on the top of the horizontal column 13. The robotic arm 2 is movably set on the surface of one of the vertical columns 14. The top of the robotic arm 2 is provided with a carving knife holder 21, and the carving knife holder 21 is provided with a carving knife 22. The operator can perform rough carving and fine carving by changing different types of carving knives 22. The setting of the robotic arm 2 ensures that the carving knife 22 can carve the surface of the hot stamping roller in a three-dimensional posture. The robotic arm 2 can be set as a multi-joint robotic arm.

[0042] A guide tube 15 is provided through the surface of the horizontal column 13. A through hole 421 is provided in the central area of ​​the collection tank 42, which is connected to the guide tube 15. A guide block 422 is provided inside the collection tank 42, with the bottom of the guide block 422 facing the area of ​​the through hole 421. The through hole 421 in the central area of ​​the collection tank 42 allows powder debris to fall into the collection tank 42 after being removed. The vibration generated by the striking block 531 causes the powder debris to flow along the guide block 422 and the collection tank 42 toward the through hole 421. The powder debris can quickly flow from the through hole 421 into the guide tube 15 and be collected by the external recycling box, thereby preventing the powder debris from sticking in the collection tank 42 and allowing the powder debris to be discharged and recycled better, further improving the cleaning effect of powder debris.

[0043] The surface of the transverse column 13 is provided with a groove 131, inside which is a slide rod 132. A slider 133 is fitted onto the surface of the slide rod 132. The bottom of the electrically controlled telescopic plate 3 is provided with a slot 31. The electrically controlled telescopic plate 3 is installed on the top of the slider 133. The bottom of the electrically controlled telescopic plate 3 is provided with a fastening bolt 34. The opposite end faces of the electrically controlled telescopic plate 3 are provided with slots 32. An anti-slip layer 33 is bonded inside the slots 32. Each set of grooves 131 is provided with a set of slide rods 132. Each adjacent slide rod 132 is provided with a slider 133. At the same time, the sliders 133 on both sides are installed correspondingly to the electrically controlled telescopic plate 3. Before engraving the hot stamping roller, the hot stamping roller needs to be installed first. Since hot stamping rollers of the same specification have different lengths, the operator can loosen the fastening bolt 34 to allow the slider 133 to slide on the slide bar 132. Then, the operator adjusts the distance between adjacent sliders 133 so that the hot stamping roller is placed on the top of the support platform 4. At the same time, the adjacent electrically controlled telescopic plates 3 symmetrically clamp and fix the two ends of the hot stamping roller. The surface of the electrically controlled telescopic plate 3 is provided with a slot 32 so that the electrically controlled telescopic plate 3 can be fitted onto the end of the hot stamping roller. An anti-slip layer 33 is bonded inside the slot 32. The anti-slip layer 33 ensures that the end of the hot stamping roller can not slide when the fastening bolt 34 is tightened, and at the same time, it can prevent the fastening bolt 34 from wearing the end of the hot stamping roller.

[0044] The inner wall of the slot 32 is provided with ejector pins 36, which clamp and fix the two sides of the hot stamping roller. The side wall of the electrically controlled telescopic plate 3 away from the support platform 4 is provided with a connecting plate 37. The inside of the connecting plate 37 is provided with a drive wheel 35. The output end of the drive wheel 35 passes through the electrically controlled telescopic plate 3 and is fixedly connected to the ejector pins 36 inside the slot 32. When the drive wheel 35 is rotated, the drive wheel 35 drives the ejector pins 36 on one side to rotate inside the slot 32, thereby driving the hot stamping roller to rotate inside the slot 32 to achieve fine engraving and cleaning of the hot stamping roller.

[0045] The support unit is located at the top of the horizontal column 13 and is used to support and install the engraving roller during the engraving process. The support unit includes a support platform 4, a support pad 41, a rotating shaft 43, a sleeve 44, and a forward and reverse motor 45. The support platform 4 is located at the top of the horizontal column 13. Arc plates 47 are provided on both sides of the top of the support platform 4. Mounting grooves 46 are provided on both sides of the support platform 4 and at the bottom of the arc plates 47. A storage groove 42 is provided on the top of the support platform 4. The rotating shaft 43 is installed inside the storage groove 42. The sleeve 44 is installed on the top of the rotating shaft 43. The forward and reverse motor 45 is installed on one side of the support platform 4, and the output end of the forward and reverse motor 45 is fixed to one end of the rotating shaft 43.

[0046] The transmission rods 56 are configured in two sets. One transmission rod 56 has a first driven wheel 57 at one end and a second driven wheel 58 at one end. One end of the rotating shaft 43 passes through the support platform 4. An intermediate shaft 433 is provided on one side of the support platform 4 and at the bottom of the rotating shaft 43. The rotating shaft 43 and the intermediate shaft 433 are driven by a gear set. Therefore, when the rotating shaft 43 rotates, the intermediate shaft 433 is driven to rotate in the opposite direction through the transmission action of the gear set. One end of the intermediate shaft 433 is provided with a first pulley 431 and one side of the rotating shaft 43 is provided with a second pulley 432. The first pulley 431 is connected to the first driven wheel 57 by belt drive, and the second pulley 432 is connected to the second driven wheel 58 by belt drive. So when the intermediate shaft 433 rotates, it synchronously drives the first pulley 431 to rotate. When the rotating shaft 43 rotates, it drives the second pulley 432 to rotate. The rotation directions of the first pulley 431 and the second pulley 432 are opposite.

[0047] After the engraving process is completed, the operator can start the forward and reverse motor 45 to drive the rotating shaft 43 and the sleeve 44 to rotate. During the rotation of the sleeve 44, the brush layer 441 scrapes and cleans the powder debris from the engraved area on the hot stamping roller surface in the contact area. During the cleaning process, since the rotating shaft 43 drives the intermediate shaft 433 to rotate, and the rotation directions of the rotating shaft 433 and the intermediate shaft 433 are opposite, the intermediate shaft 433 drives the first pulley 431 to rotate, and the rotating shaft 43 drives the second pulley 432 to rotate. The first pulley 431 and the second pulley 432 respectively drive the first driven wheel 57. When the first driven wheel 57 and the second driven wheel 58 rotate, the transmission rod 56 connected to the first driven wheel 57 and the second driven wheel 58 will drive the rotating rod 51 to rotate. The two sets of rotating rods 51 rotate in opposite directions. The rotating rod 51 will push the lever 532 and the chuck 53 in this area away from the inner wall of the mounting groove 46 through the transmission wheel 52. When the transmission wheel 52 is disengaged from the lever 532, the chuck 53 will drive the striking block 531 to strike the inner wall of the mounting groove 46 under the action of the return spring 55, thereby achieving vibration cleaning of the inner wall of the storage groove 42 and the outer surface of the hot stamping roller.

[0048] The support pad 41 is fixedly connected to the top of the arc plate 47. The support pad 41 improves the support and vibration transmission effect between the arc plate 47 and the hot stamping roller. The peeling component is set inside the support unit. It can peel off the powder debris generated during the previous engraving process from the surface of the engraving roller after the engraving is flipped. The peeling component includes a brush layer 441. The sleeve 44 is provided with a brush layer 441. The brush layer 441 is set in an odd number of groups. The brush layer 441 is set in thirteen or eleven groups. When the hot stamping roller is placed in the center of the support table 4, the single group of brush layers 441 in the central area of ​​the hot stamping roller can better clean the powder debris in the central area of ​​the hot stamping roller. The vibration generated by the cyclic impact can work with the brush layer 441 to improve the sweeping effect of powder debris. At the same time, the vibration is transmitted to the hot stamping roller area, which allows the debris in the deep scratches of the hot stamping roller to flow out faster, improving the removal effect of debris in the deep scratches. The vibration generated by the striking block 531 causes the powder debris to flow along the guide block 422 and the collection groove 42 toward the through hole 421. The powder debris can quickly flow from the through hole 421 into the guide pipe 15 and be collected by the external recycling box, which can prevent the powder debris from sticking in the collection groove 42, so that the powder debris can be better discharged and recycled, further improving the powder debris cleaning effect.

[0049] The mounting slot 46 is equipped with a striking unit, which includes a fixed block 5, a rotating rod 51, a transmission wheel 52, a chuck 53, a fixed post 54, a return spring 55, and a transmission rod 56. The fixed block 5 is installed in the central area of ​​the mounting slot 46. The rotating rod 51 is rotatably installed inside the fixed block 5. The transmission wheel 52 is respectively disposed on the surface of both ends of the rotating rod 51. The outer surface of the transmission wheel 52 is evenly arrayed with multiple sets of conical teeth 521. The transmission rod 56 is installed at the end of the rotating rod 51 away from the forward and reverse motor 45. The fixed post 54 is disposed at the bottom of the mounting slot 46, and the return spring 55 is sleeved on the fixed post 54. On the surface, the chuck 53 is rotatably sleeved on the top of the fixed post 54. The two ends of the return spring 55 are fixed to the bottom of the mounting groove 46 and the bottom of the chuck 53, respectively. A lever 532 is provided at one end of the chuck 53 near the transmission wheel 52. The lever 532 is movably connected to the transmission wheel 52. A striking block 531 is provided on one side of the chuck 53. The first pulley 431 and the second pulley 432 drive the first driven wheel 57 and the second driven wheel 58 to rotate. When the first driven wheel 57 and the second driven wheel 58 rotate, the transmission rod 56 connected to the first driven wheel 57 and the second driven wheel 58 will drive the rotating rod 51 to rotate.

[0050] During use, the hot stamping roller is placed in the center of the support platform 4. Before engraving the hot stamping roller, it is necessary to install it. Since hot stamping rollers of different specifications have different lengths, the operator can loosen the fastening bolts 34 so that the slider 133 can slide on the slide bar 132. Then, the operator adjusts the distance between the adjacent sliders 133 so that the hot stamping roller is placed on the top of the support platform 4. At the same time, the symmetrical pins 36 of the adjacent electrically controlled telescopic plates 3 clamp and fix the central shafts at both ends of the hot stamping roller. The surface of the electrically controlled telescopic plates 3 is provided with slots 32 so that the electrically controlled telescopic plates 3 can be fitted onto the ends of the hot stamping roller.

[0051] The operator then uses robotic arm 2 to control engraving knife 22 to engrave the surface of hot stamping roller in a three-dimensional manner. The operator can perform rough engraving and fine engraving by changing different types of engraving knife 22.

[0052] After the engraving process is completed, the operator can start the forward and reverse motor 45 to rotate the rotating shaft 43 and the sleeve 44. During the rotation of the sleeve 44, the brush layer 441 scrapes and cleans the powder debris from the engraved area on the hot stamping roller surface in the contact area. During the cleaning process, the rotating shaft 43 drives the intermediate shaft 433 to rotate in the opposite direction, which in turn drives the first pulley 431 to rotate. The rotating shaft 43 then drives the second pulley 432 to rotate. The first pulley 431 and the second pulley 432 then rotate... Do not cause the first driven wheel 57 and the second driven wheel 58 to rotate in opposite directions. When the first driven wheel 57 and the second driven wheel 58 rotate, the transmission rod 56 connected to the first driven wheel 57 and the second driven wheel 58 will drive the rotating rod 51 to rotate. The rotating rod 51 will push the lever 532 and the chuck 53 in this area away from the inner wall of the mounting groove 46 through the transmission wheel 52. When the transmission wheel 52 disengages from the lever 532, the chuck 53 will drive the striking block 531 to strike the inner wall of the mounting groove 46 under the action of the return spring 55.

[0053] The vibration generated by the cyclic impact, in conjunction with the brush layer 441, improves the sweeping effect of powder debris. At the same time, the vibration is transmitted to the hot stamping roller area, allowing debris in the deep grooves of the hot stamping roller to flow out more quickly, improving the removal effect of debris in the deep grooves. The vibration generated by the striking block 531 causes the powder debris to flow along the guide block 422 and the collection groove 42 toward the through hole 421. The powder debris can quickly flow from the through hole 421 into the guide tube 15 and be collected by the external recycling box, which can prevent the powder debris from sticking in the collection groove 42, so that the powder debris can be better discharged and recycled, further improving the powder debris cleaning effect.

[0054] Second Embodiment

[0055] Based on the first embodiment, before engraving the hot stamping roller, it is necessary to clamp and position it. However, in the prior art, it is impossible for the operator to quickly and efficiently squeeze and clamp the two sides of the hot stamping roller's central axis with the ejector pin 36 for rotation using only the operator's eyes. When the diameter of the hot stamping roller is different, the support positioning angle for clamping and fixing the hot stamping roller needs to be different. However, the prior art lacks the ability to adjust the positioning support according to the different diameters of the hot stamping roller, thereby reducing the clamping and fixing accuracy and efficiency of the hot stamping roller. After the engraving of the hot stamping roller is completed, it needs to be cleaned. When the diameter of the hot stamping roller is different, the effect of the top of the arc plate 47 on the cleaning of the hot stamping roller is different, and the vibration force required for vibration cleaning is different for different diameters. The prior art lacks an adaptive adjustment function, thereby reducing the effect of vibration cleaning of the hot stamping roller.

[0056] To solve the above problems, such as Figure 9As shown, the cigarette tipping paper hot stamping roller engraving machine also includes: a top hole 591 is provided inside the fixed block 5 on the side away from the rotating shaft 43. An insert rod 59 is slidably connected inside the top hole 591. The top of the insert rod 59 is hinged to the bottom of the arc plate 47. Therefore, when the top of the arc plate 47 is squeezed, the arc plate 47 correspondingly squeezes the insert rod 59 downward. The insert rod 59 moves downward inside the top hole 591. A sliding groove 593 is provided on one side of the top of the support platform 4. The bottom of the top hole 591 and the bottom of the sliding groove 593 are connected to each other through a vent pipe 592. A stable gas is sealed inside the top hole 591. When the insert rod 59 moves downward inside the top hole 591, the stable gas in the top hole 591 enters the sliding groove 593 downward along the vent pipe 592. The fixed column 54 is slidably inserted into the sliding groove 593. The bottom of the corresponding fixed column 54 moves upward under the support force of the stable gas.

[0057] The lever 532 is movably connected to the bevel gear 521. The width of the bevel gear 521 gradually decreases from one end of the transmission wheel 52 to the other. Therefore, when the fixed post 54 moves upward, the fixed post 54 drives the chuck 53 to move upward, and the chuck 53 drives the lever 532 to move upward. The meshing height between the lever 532 and the bevel gear 521 increases. When the transmission wheel 52 drives the bevel gear 521 to rotate, the angle at which the bevel gear 521 drives the lever 532 to move outward increases. Correspondingly, when the bevel gear 521 disengages from the lever 532, the return spring... The spring 55 causes the chuck 53 to rotate in the opposite direction to increase the degree of rotation. The chuck 53 causes the striking block 531 to rotate in the opposite direction to increase the degree of rotation. As a result, the striking force of the striking block 531 on the inner wall of the mounting groove 46 increases. The corresponding mounting groove 46 transmits this striking force to the support platform 4 and the top arc plate 47. The impurities located on the top of the support platform 4 are more effectively cleaned by vibration under the action of this striking force. At the same time, the vibration wave force of the arc plate 47 on the outer surface of the hot stamping roller increases, thereby enhancing the vibration cleaning effect on the hot stamping roller with an increased diameter.

[0058] The distance between the chuck 53 and the inner wall of the mounting groove 46 is less than the length of the striking block 531. The lever 532 has a wedge-shaped surface 533 on the side away from the striking block 531, with the wedge-shaped surface 533 sloping from top to bottom. This means the width of the lever 532 gradually increases from top to bottom. Therefore, when the rotating shaft 43 rotates counterclockwise, the transmission wheels 52 on both sides are driven to rotate in opposite directions via the intermediate shaft 433. The conical teeth 521 then press against the wedge-shaped surface 533 on the other side of the lever 532. When the striking block 531 presses against the inner wall of the mounting groove 46, the chuck 53 cannot... As the rotation continues, the mutual pressing contact between the conical teeth 521 and the wedge-shaped surface 533 causes the lever 532 to move downward. The lever 532 causes the chuck 53 to move downward, and the chuck 53 causes the fixed column 54 to move downward along the sliding groove 593. The stable gas in the sliding groove 593 flows in the opposite direction along the vent pipe 592 to the top hole 591. The air pressure inside the top hole 591 increases and causes the insertion rod 59 to move upward. The top of the insertion rod 59 supports the arc plate 47 and causes the arc plate 47 to rotate towards the receiving groove 42, thereby effectively achieving the supporting and positioning effect of the arc plate 47 on the hot stamping roller.

[0059] First, place the hot stamping roller between the two sets of slots 32 and adjust the gap between the two sets of electrically controlled telescopic plates 3 by adjusting the slider 133 inside the slide groove 131. After the hot stamping roller is located at the bottom inside the slot 32, the position of the hot stamping roller needs to be adjusted so that the central shaft on both sides of the hot stamping roller is in corresponding squeezing contact with the ejector pin 36.

[0060] At this time, the electrically controlled telescopic plate 3 starts and drives the hot stamping roller at the top to move downward. When the hot stamping roller reaches the top of the arc plate 47 and presses against the top of the arc plate 47, the forward and reverse motor 45 starts and drives the rotating shaft 43 to rotate counterclockwise. The rotating shaft 43, through the gear set meshing with the intermediate shaft 433, drives the intermediate shaft 433 to rotate in the opposite direction. Then, the intermediate shaft 433 drives the first driven wheel 57 to rotate clockwise through the first pulley 431. The first driven wheel 57 drives the rotating rod 51 on this side to rotate clockwise. The rotating rod 51 drives the transmission wheel 52 to rotate clockwise. The rotating shaft 43, through the second pulley 432, drives the second driven wheel 58 to rotate counterclockwise. The second driven wheel 58 drives the rotating rod 51 on this side to rotate counterclockwise. The rotating rod 51 drives the transmission wheel 52 to rotate counterclockwise. Then, the transmission wheels 52 on both sides drive the chuck 53 to rotate through the bevel teeth 521. The chuck 53 drives the striking block 531 to press against the inner wall of the mounting groove 46.

[0061] When the striking block 531 and the mounting groove 46 press against each other and cause the chuck 53 to be unable to rotate, the conical tooth 521 and the wedge-shaped surface 533 engage with each other in a wedge shape and drive the lever 532 to move downward. The lever 532 moves downward and drives the chuck 53 to move downward. The downward movement of the chuck 53 compresses the reset spring 55 and the fixing post 54 to move downward along the sliding groove 593. When the fixing post 54 moves downward, it simultaneously compresses the stabilizing gas inside the sliding groove 593. The stabilizing gas enters the top hole 591 along the vent pipe 592, increasing the air pressure inside the top hole 591. With the help of the compressive force of the stabilizing gas on the insertion rod 59, the insertion rod 59 moves upward. When the insertion rod 59 moves upward, it simultaneously drives the arc plate 47 to rotate towards the end closer to the receiving groove 42. At the same time, with the help of the two sides... The arc-shaped plates 47 move synchronously and have an arc-shaped structure. When the arc-shaped plates 47 move upward, they apply upward pressure to both sides of the hot stamping roller. This pressure causes the hot stamping roller to move continuously towards the center inside the slot 32, further improving the centering positioning effect of the hot stamping roller and ensuring the subsequent engraving and cleaning effect of the hot stamping roller. As the upward pressure applied to the hot stamping roller by the arc-shaped plates 47 on both sides increases, the hot stamping roller moves upward synchronously. The two sides of the hot stamping roller's axis move upward to the center position of the ejector pin 36. When the two sides of the hot stamping roller's axis are located at the ejector pin 36, the forward and reverse motor 45 stops working and continues to move the slider 133, so that the two sets of ejector pins 36 position the axis of the hot stamping roller, further improving the subsequent engraving and cleaning effect of the hot stamping roller.

[0062] A distance sensor can be installed on the inner top of the slot 32. When the hot stamping roller is at the center of the slot 32, the diameter of the hot stamping roller can be obtained by measuring the distance value detected by the distance sensor and the diameter value of the slot 32. When the hot stamping roller moves upward along the slot 32, the corresponding upward distance value of the hot stamping roller can be obtained. Furthermore, it is possible to quickly determine whether the axis of the hot stamping roller has reached the end of the ejector pin 36, thereby improving the clamping and fixing effect and accuracy of the hot stamping roller.

[0063] After the hot stamping roller is clamped and fixed, the position of the slider 133 is limited by the fastening bolt 34. At the same time, the electric telescopic plate 3 is started and drives the hot stamping roller to rise and move to the appropriate position. At this time, the engraving knife 22 inside the engraving knife holder 21 engraves the outer surface of the hot stamping roller, and drives the hot stamping roller to rotate by rotating the drive wheel 35, further improving the engraving accuracy and engraving effect of the hot stamping roller.

[0064] After the engraving of the hot stamping roller is completed, the engraving knife 22 stops working, and the outer surface of the hot stamping roller needs to be cleaned. At this time, the forward and reverse motor 45 starts and drives the rotating shaft 43 to rotate clockwise. The clockwise rotation of the rotating shaft 43 drives the brush layer 441 to rotate through the sleeve 44. At the same time, the electrically controlled telescopic plate 3 starts to move downward, and the electrically controlled telescopic plate 3 drives the hot stamping roller to move downward. The bottom of the hot stamping roller is pressed and contacted with the two arc-shaped plates 47 and then with the brush layer 441. When the brush layer 441 rotates, it cleans the outer surface of the hot stamping roller with rotating brushes. This, together with the drive wheel 35 driving the hot stamping roller to rotate, further improves the cleaning effect of the hot stamping roller.

[0065] Furthermore, the rotating shaft 43 drives the intermediate shaft 433 to rotate counterclockwise via the gear set. This, in turn, drives the rotating rods 51 on both sides to rotate in opposite directions via the first pulley 431, the second pulley 432, the first driven wheel 57, and the second driven wheel 58. The rotating rods 51 drive the bevel gear 521 to rotate via the transmission wheel 52. The bevel gear 521 and the lever 532 engage with each other and drive the chuck 53 to twist the return spring 55 to rotate away from the inner wall of the mounting groove 46. The chuck 53 drives the striking block 531 to move away from the inner wall of the mounting groove 46. When the bevel gear 521 disengages from the lever 532, the torque of the return spring 55 drives the chuck 53 to rotate closer to the inner wall of the mounting groove 46. When the chuck 53 rotates, it simultaneously drives the striking block 531 to rotate closer to the inner wall of the mounting groove 46 and engages with the mounting plate. The inner wall of the mounting groove 46 is struck, and the above process is repeated continuously, causing the striking block 531 to vibrate and strike the inner wall of the mounting groove 46. The striking force received by the mounting groove 46 is simultaneously transmitted to the top of the inner wall of the storage groove 42 and the top of the curved plate 47. Dust and impurities attached to the inner wall of the storage groove 42 are then removed under the action of the vibrating striking force and recycled into the bottom guide tube 15 for recycling under the rotating cleaning action of the brush layer 441. At the same time, when the curved plate 47 is vibrated and struck, a vibrating striking force is simultaneously applied to the hot stamping roller. Dust and impurities adhering to the outer surface of the hot stamping roller can be effectively removed from the hot stamping roller and fall to the top of the curved plate 47. Finally, they fall into the storage groove 42 for recycling under the curved plate 47, further improving the vibration cleaning effect on the hot stamping roller.

[0066] Furthermore, as the diameter of the hot stamping roller increases, when the outer surface of the hot stamping roller presses against the top of the brush layer 441, the force exerted by the hot stamping roller on the top of the arc-shaped plates 47 on both sides increases synchronously. This increases the downward tilt angle of the arc-shaped plates 47, and the distance the bottom pressing rod 59 of the arc-shaped plates 47 moves downward along the top hole 591 increases. The stabilizing gas inside the top hole 591 enters the sliding groove 593 along the vent pipe 592. The increased amount of stabilizing gas inside the sliding groove 593 increases the force exerted by the stabilizing gas on the bottom of the fixed column 54. The fixed column 54 drives the top chuck 53 to move upward. Simultaneously, the upward movement of the chuck 53 drives the lever 532 to move upward. As the lever 532 moves upward, the contact height with the conical teeth 521 increases, thus the transmission wheel 52 drives the conical... When the conical tooth 521 rotates and drives the lever 532 to rotate by mutual compression, the angle of rotation of the lever 532 driven by the conical tooth 521 increases. The lever 532 drives the chuck 53 to twist the return spring 55 and rotates at an increased angle. The elastic potential energy stored in the return spring 55 increases. When the conical tooth 521 disengages from the lever 532, the torque of the return spring 55 drives the chuck 53 to rotate in the opposite direction and drives the striking block 531 to increase the striking force on the inner wall of the mounting groove 46. The corresponding vibration striking force on the mounting groove 46 increases. The vibration striking force transmitted from the mounting groove 46 to the top of the arc plate 47 increases. The vibration striking force applied by the arc plate 47 to the hot stamping roller increases. Therefore, the arc plate 47 can adaptably perform vibration cleaning on the hot stamping roller with a larger diameter, effectively improving the adaptive cleaning effect on the hot stamping roller.

[0067] After cleaning is completed, the electrically controlled telescopic plate 3 drives the hot stamping roller to move upward and return to its original position. At the same time, the fastening bolt 34 is opened, the slider 133 moves in the opposite direction, and the hot stamping roller is taken out along the slot 32, thus completing the engraving and cleaning process of the hot stamping roller. When engraving is required for subsequent hot stamping rollers, the above process can be repeated continuously.

[0068] This device is simple to operate, stable and efficient. It can not only position and clamp the hot stamping roller with high accuracy and good clamping effect, but also adjust the positioning and clamping position according to the hot stamping roller with different diameters, making it highly adaptable and stable. After the hot stamping roller is engraved, it simultaneously vibrates and cleans the outer surface of the hot stamping roller and the inside of the storage groove 42, resulting in stronger cleaning and better synchronization and coordination. Furthermore, it can adaptively adjust the vibration and tapping force on the outer surface of the hot stamping roller according to the diameter of the hot stamping roller, resulting in better vibration cleaning effect, energy saving and emission reduction, and environmental protection.
