Description

Technical Field

[0001] This invention relates to the field of cigarette box substrate production technology, and in particular to a laser cardboard vacuum aluminum plating equipment. Background Technology

[0002] Vacuum metallization of laser cardboard is a common process used in cigarette box packaging to enhance the visual appeal and anti-counterfeiting features of the packaging. In cigarette box production, the vacuum metallization process of laser cardboard involves multiple steps, among which coating is a key step. Coating involves applying a special coating to the surface of the laser cardboard to facilitate the subsequent vacuum metallization operation.

[0003] Before coating, it is crucial to treat the surface of the cardstock and clean off dust, oil, and other impurities, as these can affect the adhesion and uniformity of the coating. Cleaning methods include air blowing, wiping, or other techniques. However, in practice, many cleaning tools (such as brushes and air blowers) are fixed in place on the work platform. In the production line, the laser cardstock needs to be constantly moving to ensure production efficiency and coating uniformity. This can lead to insufficient cleaning time for the cleaning tools on the areas requiring cleaning, resulting in incomplete cleaning. Summary of the Invention

[0004] The purpose of this invention is to provide a laser cardboard vacuum aluminizing equipment to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a vacuum aluminum plating device for laser cardboard, comprising a base, a working shell fixedly connected to the top of the base, a support plate fixedly connected to the inner wall of the working shell, a processing mechanism disposed on the inner wall of the working shell, several air blowing mechanisms arranged in a linear array on the outer wall of the processing mechanism, and pressure roller mechanisms symmetrically arranged on the outer wall of the working shell. The processing mechanism includes a motor fixedly connected to the outer wall of the working shell, sprocket shafts symmetrically rotatably connected to the inner wall of the working shell, the output end of the motor fixedly connected to the outer wall of one side of the sprocket shaft, chain plates meshing with the outer walls of the two sprocket shafts, several mounting plates fixedly connected in a linear array on the outer walls of the chain plates, sliding plates slidably connected to the outer walls of the mounting plates, and brushes fixedly connected to the outer walls of the sliding plates.

[0006] Preferably, the processing mechanism further includes several reciprocating screws rotatably connected to the inner walls of several mounting plates, several sliding plates being threadedly connected to the outer walls of several reciprocating screws, several reciprocating screws being symmetrically fixedly connected to the outer walls of several reciprocating screws, and drive racks being symmetrically fixedly connected to the inner walls of the working housing, with several driven gears on the same side being meshed with the outer walls of the drive racks.

[0007] Preferably, the processing mechanism further includes several fixed plates that are symmetrically distributed and fixedly connected to the outer wall of the support plate, several toothed plates that are fixedly connected to the outer wall of the several fixed plates on the same side, and inclined plates that are fixedly connected to the outer wall of the several toothed plates.

[0008] Preferably, the air blowing mechanism includes two damping turntables that are symmetrically distributed and fixedly connected to the inner wall of the slide plate, and an air blowing box is fixedly connected to the outer wall of the two damping turntables. Air cylinder assemblies are symmetrically arranged on the inner wall of the mounting plate.

[0009] Preferably, the blowing mechanism further includes several conical cylinders that are fixedly connected and penetrate the inner wall of the blowing box, and the several conical cylinders are distributed in a rectangular array.

[0010] Preferably, the air blowing mechanism further includes two push blocks that are symmetrically distributed and fixedly connected to the outer wall of the mounting plate, and rubber pads are fixedly connected to the outer wall of each push block.

[0011] Preferably, the air cylinder assembly includes an air cylinder fixedly connected to the inner wall of the mounting plate, a piston rod slidably connected to the inner wall of the air cylinder, the outer wall of the piston rod being fixedly connected to the outer wall of the slide plate, a one-way valve connected through the outer wall of the air cylinder, a through air hose fixedly connected to both the outer wall of the air box and the outer wall of the air cylinder, and a through one-way valve fixedly connected to the inner wall of the air box.

[0012] Preferably, the pressure roller mechanism includes a second motor fixedly connected to the outer wall of the working housing, a transition roller rotatably connected to the inner wall of the working housing, the output end of the second motor fixedly connected to the outer wall of the transition roller, sliders symmetrically slidably connected to the inner wall of the working housing, and pressure rollers rotatably connected to the outer walls of the two sliders together.

[0013] Preferably, the pressure roller mechanism further includes two threaded rods that are symmetrically distributed and threadedly connected to the inner wall of the working housing. The bottom of the threaded rods on the same side is rotatably connected to the top of the slider, and a rotating plate is fixedly connected to the top of each of the two threaded rods.

[0014] Preferably, the pressure roller mechanism further includes a negative pressure fan blade fixedly connected to the outer wall of the transition roller, a negative pressure air duct fixedly connected to the outer wall of the working shell, a separation cylinder fixedly connected to the outer wall of the working shell, a first suction pipe fixedly connected to the top of the separation cylinder and the inner wall of the negative pressure air duct, a sedimentation cylinder threadedly connected to the outer wall of the separation cylinder, a through trapezoidal box fixedly connected to the inner wall of the working shell, and a second suction pipe fixedly connected to the bottom of the trapezoidal box and the outer wall of the separation cylinder.

[0015] Due to the adoption of the above technical solution, the beneficial effects achieved by the present invention compared with the prior art are as follows: The sprocket shaft, chain plate, mounting plate, and brush configured in this invention allow the brush to move synchronously with the continuously conveyed laser card paper. This extends the cleaning time for impurities on the laser card paper surface while the paper continues to move, preventing insufficient cleaning time due to the paper's continuous movement. This avoids situations where the brush cannot thoroughly clean impurities from the laser card paper surface, which could negatively impact subsequent coating and aluminizing processes.

[0016] The reciprocating screw, driven gear, and drive rack of this invention engage with each other on the same side when the chain plate reciprocates and drives the mounting plate to move, causing the reciprocating screw to rotate, thereby driving the slide plate to move back and forth, which in turn drives the brush to move back and forth, cleaning away impurities from the surface of the laser card.

[0017] The air blowing box and air cylinder assembly of this invention utilize the reciprocating movement of the slide plate to allow the air cylinder assembly to draw in and expel air, and blow the airflow towards the area in front of the brush's moving direction through the air blowing box, which helps to improve the cleaning effect of the brush on the surface of the laser card paper and ensures that the impurities are completely removed.

[0018] The damping turntable and push block of this invention utilize the reciprocating movement of the slide plate to drive the air blowing box to reciprocate. Regardless of which direction the slide plate moves, the air blowing box always faces the area in front of the moving direction of the brush on the surface of the laser card, ensuring that the airflow exiting through the air blowing box can continuously cooperate with the brush to clean impurities on the surface of the laser card.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] Example 1, as Figures 1-7 As shown, a laser cardboard vacuum aluminum plating device includes a base 1, a working shell 2 fixedly connected to the top of the base 1, a support plate 3 fixedly connected to the inner wall of the working shell 2, a processing mechanism 4 provided on the inner wall of the working shell 2, several air blowing mechanisms 5 arranged in a linear array on the outer wall of the processing mechanism 4, and pressure roller mechanisms 6 symmetrically arranged on the outer wall of the working shell 2. The processing mechanism 4 includes a motor 41 fixedly connected to the outer wall of the working shell 2, sprocket shafts 42 symmetrically rotatably connected to the inner wall of the working shell 2, the output end of the motor 41 fixedly connected to the outer wall of one side of the sprocket shaft 42, chain plates 43 meshing with the outer walls of the two sprocket shafts 42, several mounting plates 44 fixedly connected in a linear array on the outer wall of the chain plates 43, sliding plates 45 slidably connected to the outer walls of the mounting plates 44, and brushes 46 fixedly connected to the outer walls of the sliding plates 45.

[0023] The aforementioned chain plate 43 is mainly composed of chain plate body, connecting pin, roller, pin shaft, protective sleeve, connecting ring, fastener and other components. Through precise design and the use of high-strength materials, these parts ensure that the chain plate 43 has sufficient strength, stability and durability in bearing load and transmission process. It mainly achieves transmission by meshing with the sprocket part in the two sprocket shafts 42. This is a mature technology in the prior art, and its structure and working principle will not be elaborated further in this solution. The mounting positions of the aforementioned mounting plates 44 on the outer wall of the chain plate 43 do not affect the reciprocating transmission of the chain plate 43 without affecting the operation of its own components. In a specific implementation of the present invention, the device is placed in a suitable position to process the coating work before the aluminizing of laser cardboard, and is connected to other related production lines that continuously transport and aluminize laser cardboard. The laser card is passed through the position between the two pressure roller mechanisms 6 in sequence. The two pressure roller mechanisms 6 are turned on and, together with other aluminum-plating related production line equipment, the laser card is continuously conveyed from left to right. At this time, the side of the laser card that does not need to be cleaned is in contact with the support plate 3. The motor 41 is turned on, which drives the sprocket shaft 42 to rotate counterclockwise, causing the chain plate 43 to rotate counterclockwise back and forth. This drives several mounting plates 44 to move from left to right, which in turn drives several sliding plates 45 to move back and forth from left to right, which in turn drives several brushes 46 to move back and forth from left to right. This cleans the impurities on the side of the laser card that needs to be coated before the subsequent aluminum plating work, preventing impurities from affecting the adhesion and uniformity of the coating. Several brushes 46 move from left to right, synchronously with the laser card paper moving from left to right. Thus, when the brush 46 on the left cleans impurities on a certain area of ​​the laser card paper that has just entered the working housing 2, and this area continues to move from inside to outside the working housing 2, the brush 46 on the left maintains its cleaning state on this area. With the laser card paper continuously moving, the cleaning time of the brushes 46 on the surface of the laser card paper is extended, avoiding a situation where the cleaning time is too short due to the continuous movement of the laser card paper, which would prevent the brushes 46 from thoroughly cleaning the impurities on the surface of the laser card paper, thus avoiding a series of adverse effects on the subsequent coating and aluminizing processes of the laser card paper.

[0024] Example 2, as Figures 7-12As shown, the processing mechanism 4 also includes several reciprocating screws 47 that are rotatably connected to the inner walls of several mounting plates 44, several sliding plates 45 that are threadedly connected to the outer walls of several reciprocating screws 47, several driven gears 48 that are symmetrically fixedly connected to the outer walls of several reciprocating screws 47, and drive racks 49 that are symmetrically fixedly connected to the inner wall of the working housing 2, and several driven gears 48 on the same side that are meshed with the outer walls of drive racks 49. The processing mechanism 4 also includes several fixed plates 410 that are symmetrically distributed and fixedly connected to the outer wall of the support plate 3. Several toothed plates 411 are fixedly connected to the outer wall of the several fixed plates 410 on the same side. Inclined plates 412 are fixedly connected to the outer wall of the several toothed plates 411. The air blowing mechanism 5 includes two damping turntables 52 that are symmetrically distributed and fixedly connected to the inner wall of the slide plate 45. An air blowing box 51 is fixedly connected to the outer wall of the two damping turntables 52. An air cylinder assembly 56 is symmetrically arranged on the inner wall of the mounting plate 44. The air blowing mechanism 5 also includes several conical cylinders 53 that are fixedly connected and pass through the inner wall of the air blowing box 51, and the several conical cylinders 53 are distributed in a rectangular array. The air blowing mechanism 5 also includes two push blocks 54 that are symmetrically distributed and fixedly connected to the outer wall of the mounting plate 44, and rubber pads 55 are fixedly connected to the outer wall of the two push blocks 54. The air pump assembly 56 includes an air pump 561 fixedly connected to the inner wall of the mounting plate 44, a piston rod 562 slidably connected to the inner wall of the air pump 561, the outer wall of the piston rod 562 fixedly connected to the outer wall of the slide plate 45, a one-way valve 563 connected through the outer wall of the air pump 561, a through air hose 564 fixedly connected to the outer wall of the air box 51 and the outer wall of the air pump 561, and a through one-way valve 565 fixedly connected to the inner wall of the air box 51.

[0025] The design of the aforementioned driven gears 48 and drive rack 49 all meet the condition of re-meshing after disengagement; The two damping turntables 52 mentioned above are composed of a small rotating shaft, two discs and a damping device. This is a mature technology in the prior art. This solution only borrows the function of the fixed object to which it can rotate and the state is not easily changed after rotation. Its structure and working principle will not be elaborated further. The aforementioned one-way valve 563 and one-way valve 565 are both mature technologies in the prior art. Their cooperation with the piston rod 562 allows the air cylinder assembly 56 to smoothly draw in and exhaust air. The structure and working principle of these components will not be elaborated further in this solution. In a specific implementation of the present invention, when the mounting plate 44 moves from left to right, it will drive both driven gears 48 to move. When the brush 46 moves to a certain position with the bristles facing down, the driven gear 48 on the same side and the drive rack 49 will re-engage. At this time, the mounting plate 44 will drive the two driven gears 48 to continue moving from left to right, which will cause both driven gears 48 to rotate, thereby causing the reciprocating screw 47 to rotate, thereby driving the slide plate 45 to move back and forth, thereby driving the brush 46 to move back and forth, cleaning the impurities on the surface of the laser cardboard. When the brush 46 is in the downward-facing position to clean impurities on the surface of the laser card, the air box 51 is tilted at a certain angle so that its air outlet is always facing the area in front of the moving direction of the brush 46. When the slide plate 45 moves back and forth, it repeatedly pulls and pushes the two piston rods 562, causing the two piston rods 562 to slide back and forth in the two air cylinders 561 respectively. When the piston rod 562 slides away from the one-way valve 563, the space between the piston rod 562 and the one-way valve 563 in the air cylinder 561 increases, and the air pressure decreases. At this time, When check valve 563 opens, external air enters air cylinder 561 through check valve 563. When piston rod 562 slides closer to check valve 563, the space between piston rod 562 and check valve 563 in air cylinder 561 becomes smaller, and the air pressure returns to normal. At this time, check valve 563 closes, and the air entering air cylinder 561 is squeezed into air box 51 through air hose 564 and blown towards the area in front of the moving direction of brush 46. This helps to improve the cleaning effect of brush 46 on impurities on the surface of laser card paper and ensures that impurities are completely removed. When the brush 46 is in the downward position, the several conical cylinders 53 are all in a state where the side with the larger diameter is on top and the side with the smaller diameter is on the bottom. In this way, the air entering the air box 51 will enter from the side with the larger diameter of the several conical cylinders 53 and exit from the side with the smaller diameter. This helps to accelerate and concentrate the airflow, enhance the impact force of the airflow, and make the airflow work better with the brush 46 to clean the impurities on the surface of the laser card. The one-way valve 565 can prevent the gas entering the air box 51 from flowing back. As the skateboard 45 continues to move towards the push block 54, it will cause the air box 51 to continue moving towards the push block 54. After the air box 51 moves to contact the rubber pad 55, the skateboard 45 will cause the air box 51 to continue moving towards the push block 54 for a certain distance. During this movement, the push block 54 will squeeze the air box 51, causing the air box 51 to rotate. When the skateboard 45 moves to the end of one side, the air box 51 will rotate so that its air outlet faces the front area of ​​the opposite side of the previous moving direction of the brush 46. In this way, when the skateboard 45 moves to the other side, the air box 51 will continue to blow air onto the front area of ​​the moving direction of the brush 46, thus ensuring that the airflow can continuously cooperate with the brush 46 to clean the impurities on the surface of the laser card.

[0026] Example 3, as Figures 13-14 As shown, the pressure roller mechanism 6 includes a second motor 61 fixedly connected to the outer wall of the working housing 2, a transition roller 62 rotatably connected to the inner wall of the working housing 2, the output end of the second motor 61 fixedly connected to the outer wall of the transition roller 62, sliders 63 symmetrically slidably connected to the inner wall of the working housing 2, and pressure rollers 64 rotatably connected to the outer walls of the two sliders 63. The pressure roller mechanism 6 also includes two threaded rods 65 that are symmetrically distributed and threadedly connected to the inner wall of the working housing 2. The bottom of the threaded rods 65 on the same side is rotatably connected to the top of the slider 63, and a rotating plate 66 is fixedly connected to the top of the two threaded rods 65. The pressure roller mechanism 6 also includes a negative pressure fan blade 67 fixedly connected to the outer wall of the transition roller 62, a negative pressure air duct 68 fixedly connected to the outer wall of the working housing 2, a separation cylinder 610 fixedly connected to the outer wall of the working housing 2, a first dust suction pipe 69 fixedly connected to the top of the separation cylinder 610 and the inner wall of the negative pressure air duct 68, a sedimentation cylinder 611 threadedly connected to the outer wall of the separation cylinder 610, a through trapezoidal box 613 fixedly connected to the inner wall of the working housing 2, and a second dust suction pipe 612 fixedly connected to the bottom of the trapezoidal box 613 and the outer wall of the separation cylinder 610.

[0027] The aforementioned motor 41 and the two motors 61 are all servo motors, which are mature technologies in the existing technology. This solution only borrows their function of controlling the rotation speed, number of rotations and start / stop at any time, and will not elaborate on their structure and working principle. Several ventilation holes are provided on the outer wall of the aforementioned negative pressure ventilation duct 68; In a specific implementation of this invention, before cleaning the surface impurities of the laser card paper to be coated using this device, the laser card paper is placed between two toothed plates 411 and passes sequentially between the transition roller 62 and the pressure roller 64 on the same side. The two rotating plates 66 are rotated to drive the two threaded rods 65 to rotate, thereby driving the two sliders 63 to move up and down, which in turn drives the pressure roller 64 to move up and down. The distance between the transition roller 62 and the pressure roller 64 on the same side is adjusted to a suitable distance for the conveying and production line of the laser card paper. The two motors 61 are turned on to drive the two transition rollers 62 to rotate clockwise, ensuring that the laser card paper is in a continuous conveying state in conjunction with other aluminum plating work related to the production line. The two pressure roller mechanisms 6 enable the processing mechanism 4 to restrict the movement of the laser card paper when cleaning impurities on the surface of the laser card paper without affecting and ensuring the continuous feeding of the laser card paper. This ensures the stability of the laser card paper's movement position and prevents the laser card paper from shifting during processing, thereby ensuring the stability of the processing mechanism 4 when cleaning impurities on the surface of the laser card paper. When the brush 46 reciprocates to clean the impurities on the surface of the laser card, it will continue to move a certain distance from the edge of the support plate 3 when it moves to the end of one side along the reciprocating screw 47, thereby cleaning the impurities cleaned off the laser card from the support plate 3. As the brush 46 continues to move from the edge of the support plate 3, it will come into contact with several toothed plates 411. Since the installation position of the toothed plates 411 is slightly higher than the top of the support plate 3, the brush bristles of the brush 46 will repeatedly come into contact with and release the toothed plates 411 in turn during the continuous reciprocating movement, which will cause the brush bristles to vibrate. This helps to clean the impurities attached to the brush bristles. The impurities cleaned off the laser card by the brush 46 will enter the trapezoidal box 613. While several brushes 46 clean impurities from the surface of the laser cardboard, two transition rollers 62 rotate, driving two negative pressure fan blades 67 to generate negative pressure. Impurities that fall into or are suspended near the trapezoidal box 613 are drawn into the suction pipe 612 through suction pipe one 69 and suction pipe two 612, and then into the separation cylinder 610. Due to the design of the separation cylinder 610 and the presence of negative pressure adsorption centrifugal force, the impurities in the separation cylinder 610 are separated from the gas and remain in the separation cylinder 610, eventually settling in the sedimentation cylinder 611. The gas that separated the impurities is drawn into suction pipe one 69 and further into the negative pressure air duct 68 for discharge. This process collects the impurities cleaned from the surface of the laser cardboard, preventing the gas carrying impurities from being directly discharged into the external environment and causing environmental pollution.
