Description

Technical Field

[0001] The invention relates to the technical field of cigarette box substrate production, and in particular to a laser cardboard film pressing device. Background Art

[0002] The laser cardboard film in the production of cigarette boxes is one of the important base materials for making cigarette boxes. The meaning of laser cardboard film pressing is to transfer the holographic pattern on the laser film to the cigarette box base material (such as white cardboard or gray-based white paper) by heating and pressurizing, so that it has glare, anti-counterfeiting and decorative functions.

[0003] In the production of cigarette boxes, the coating process in laser cardboard film pressing refers to evenly applying a layer of coating on the surface of the substrate to facilitate the subsequent film pressing process. The main object of the coating process is usually the surface of the paper substrate, which is the part that carries the laser film.

[0004] Before the laser cardboard film is pressed in the production of cigarette boxes, the paper substrate is easily coated and the coating fails to adhere firmly to the paper substrate after coating, resulting in shedding and peeling. This makes it impossible for the coated paper substrate and the laser film to fully fit together, thus bringing a series of adverse effects on the subsequent laser cardboard film molding work.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] The motor 3 is a servo motor, which is a mature technical means in the prior art. The present invention only uses its function of controlling the rotation speed, number of rotations and start and stop of the object at any time, and its structure and working principle will not be elaborated here. The two rubber wheels 42 are both abrasive belt rubber wheels, which are usually used in conjunction with the abrasive belt 46. The elasticity of the rubber wheels helps the abrasive belt 46 to apply pressure evenly, reducing damage to the workpiece during processing. The abrasive belt 46 is brought into contact with the workpiece surface by a certain pressure, thereby effectively removing material. This is a mature technical means in the prior art, and the present invention will not elaborate on its structure and working principle in detail. The meshing connections between the five gears 44 and the toothed belt 45 all meet the wrap angle requirements required for transmission; In the specific implementation of the present invention, the device is placed in a suitable position for processing cigarette box paper substrates and is connected to other related production lines for conveying cigarette box paper substrates and laminating laser cardboard films; During the continuous conveying of the paper substrate by the conveying device, the paper substrate is placed between the two pressing roller assemblies 49 . At this time, the continuously moving paper substrate is in a state where the side to be roughened is in proper contact with the surface of the abrasive belt 46 . Turn on the motor 3 to drive the rotating shaft 41 to rotate, thereby driving the gear 44 installed on the rotating shaft 41 to rotate, thereby driving the toothed belt 45 to rotate, thereby driving the remaining gears 44 to rotate, thereby driving the two rubber wheels 42 and the two transition rollers 43 to rotate, so that the sanding belt 46 continues to rotate back and forth to grind the surface of the paper substrate, thereby roughening the surface of the paper substrate used for laser cardboard film molding before it undergoes the coating process, so that the coating can adhere more firmly to the paper substrate, which can increase the contact area between the coating and the paper substrate, improve the adhesion of the coating, and reduce the shedding or peeling phenomenon of the coating after the subsequent paper substrate is coated, thereby preventing such coating shedding or peeling from having a bad influence on the subsequent laser cardboard film molding work.

[0025] Example 2, as Figure 4-Figure 6 As shown, the limiting assembly 48 includes a roller 481 fixedly connected to the inner wall of the limiting housing 47, a plurality of telescopic rods 482 are fixedly connected to the top of the roller 481, the tops of the plurality of telescopic rods 482 are fixedly connected to the inner wall of the limiting housing 47, the outer walls of the plurality of telescopic rods 482 are sleeved with springs 483, the outer walls of the plurality of springs 483 are fixedly connected to the top of the roller 481, and the outer walls of the plurality of springs 483 are fixedly connected to the inner wall of the limiting housing 47; The pressure roller assembly 49 includes two symmetrically distributed mounting frames 491 fixedly connected to the top of the shell 2, the inner walls of the two mounting frames 491 are slidably connected to a slider 492, the outer walls of the two sliders 492 are rotatably connected to a pressure roller 493, the inner walls of the two mounting frames 491 are threadedly connected to a turntable screw 494, and the bottom of the turntable screw 494 on the same side is rotatably connected to the top of the slider 492.

[0026] In a specific implementation of the present invention, before the surface of the paper substrate is roughened by the processing mechanism 4, the paper substrate is sequentially passed between the transition roller 43 and the pressure roller 493 on the same side. The two turntable screws 494 are rotated to drive the two sliders 492 to move up and down, thereby driving the pressure roller 493 to move up and down. The distance between the transition roller 43 and the pressure roller 493 on the same side is adjusted to a suitable distance to match the transportation of the paper substrate and the production line. The arrangement of the two pressure roller assemblies 49 allows the sanding belt 46 to reciprocate to roughen the surface of the paper substrate. Under the premise of not affecting the continuous transportation of the paper substrate, the movement of the paper substrate is restricted to ensure that the position of the paper substrate on the sanding belt 46 is stable, thereby ensuring the uniformity of the roughening treatment, preventing the paper substrate from shifting or wrinkling during the processing, and ensuring that each part receives the same roughening treatment. The plurality of rollers 481 are in contact with the toothed belt 45. When the five gears 44 rotate to drive the toothed belt 45 to rotate back and forth, the plurality of rollers 481 limit the toothed belt 45. The plurality of telescopic rods 482 provide vertical support for the plurality of springs 483 .

The outer walls of the plurality of springs 517 are fixedly connected to the inner wall of the sliding housing 514. The brush assembly 52 includes two symmetrically distributed fixed blocks 521 fixedly connected to the outer wall of the shell 1 2, a fixed block 2 522 symmetrically fixedly connected to the outer wall of the shell 1 2, a reciprocating screw 2 524 rotatably connected to the inner wall of the fixed block 1 521 and the inner wall of the fixed block 2 522 on the same side, a bevel gear 2 523 fixedly connected to the outer wall of the two reciprocating screws 2 524, the outer wall of the bevel gear 2 523 on the same side is meshedly connected to the outer wall of the bevel gear 1 513, a slider 2 525 is threadedly connected to the outer wall of the two reciprocating screws 2 524, the outer wall of the two sliders 2 525 is slidably connected to the inner wall of the shell 1 2, and a brush 526 is rotatably connected to the inner wall of the two sliders 2 525; The brush assembly 52 also includes two racks 528 symmetrically distributed and fixedly connected to the inner wall of the housing 2. The outer wall of the brush 526 is symmetrically connected to a gear 527 for rotation. The outer wall of the gear 527 on the same side is meshed with the outer wall of the rack 528. The heat absorption assembly 53 includes a heat dissipation housing 531 fixedly connected to the inner wall of the housing 1 2. The outer wall of the rotating shaft 41 is rotatably connected to the inner wall of the heat dissipation housing 531. The inner wall of the heat dissipation housing 531 is symmetrically fixedly connected to the heat conduction plates 532. The outer walls of the two heat conduction plates 532 are fixedly connected to a plurality of heat dissipation aluminum fins 533. The blowing assembly 54 includes an air cylinder 542 fixedly connected to the inner wall of the shell 1 2, a piston rod 541 is slidably connected to the inner wall of the air cylinder 542, the outer wall of the piston rod 541 is fixedly connected to the outer wall of the slider 2 525 on one side, an air inlet valve 543 is connected through the outer wall of the air cylinder 542, an air supply hose 544 is fixedly connected to the outer wall of the air cylinder 542 and the outer wall of the heat dissipation shell 531, and an air outlet valve 545 is connected through the outer wall of the heat dissipation shell 531.

[0028] The inlet valve 543 and the outlet valve 545 are both one-way valves, which are mature technical means in the prior art. The cooperation between the two and the piston rod 541 allows the blowing assembly 54 to efficiently and smoothly complete the intake and exhaust of gas. They are mature technical means in the prior art, and this solution will not elaborate on their structure and working principle in detail. The cleaning rubber block 516 is a sanding belt cleaning block, which is a tool for cleaning the surface of the sanding belt. It is a mature technical means in the prior art, and this solution will not elaborate on its structure and working principle. In a specific implementation of the present invention, when the motor 3 is turned on to drive the rotating shaft 41 to rotate, thereby causing the sanding belt 46 to reciprocate and roughen the surface of the paper substrate, the pulley assembly 511 drives the reciprocating screw 512 to rotate, thereby driving the sliding housing 514 to reciprocate, and thus driving the cleaning rubber block 516 to reciprocate, thereby cleaning the dirt attached to the surface of the sanding belt 46 caused by the roughening of the paper substrate surface, thereby effectively removing the dirt attached to the surface of the sanding belt 46, ensuring that the sanding belt 46 always maintains the best working condition, and avoiding the problem of uneven surface treatment or inconsistent roughness of the paper substrate caused by dirt accumulation and clogging on the surface of the sanding belt 46; The plurality of springs 517 allow the cleaning rubber block 516 to automatically adjust its contact pressure on the sanding belt 46 according to the unevenness of the sanding belt 46 surface, the accumulation of dirt, and the wear of the cleaning rubber block 516 during the continuous cleaning of dirt on the sanding belt 46, thereby ensuring that the contact surface between the cleaning rubber block 516 and the sanding belt 46 maintains a good cleaning effect. The rotation of the reciprocating screw 1 512 drives the two bevel gears 1 513 to rotate, thereby driving the two bevel gears 2 523 to rotate, thereby driving the two reciprocating screws 2 524 to rotate, thereby driving the two sliders 2 525 to move back and forth, thereby driving the brushes 526 to move back and forth, and similarly cleaning the dirt on the surface of the sanding belt 46. In the specific implementation of this device, the rotation direction of the sanding belt 46 is such that the position on the surface of the sanding belt 46 that needs to be cleaned passes through the brushes 526 first, so that the brushes 526 clean the larger particles of dirt or impurities on the surface of the sanding belt 46 before the cleaning rubber blocks 516, which can significantly reduce the dirt burden when the cleaning rubber blocks 516 are in direct contact with the surface of the sanding belt 46, thereby improving the cleaning effect of the dirt on the surface of the sanding belt 46 and preventing larger dirt particles from directly contacting the surface of the cleaning rubber blocks 516, thereby reducing the wear of the cleaning rubber blocks 516 and extending its service life. The two sliders 525 both reciprocate, thereby driving the two gears 527 to reciprocate and mesh with the racks 528 on the same side, so that the brushes 526 rotate when they reciprocate to clean the surface of the sanding belt 46, which helps to improve cleaning efficiency, evenly distribute the wear of the bristles, avoid local overuse of the brushes 526, and extend the service life of the brushes 526; During the process of the sanding belt 46 continuously rotating to roughen the surface of the paper substrate, frictional heat is generated. During the reciprocating rotation, the sanding belt 46 contacts both heat conducting plates 532 . Both heat conducting plates 532 absorb the heat generated by the sanding belt 46 and transfer it to the plurality of heat dissipating aluminum fins 533 . This effectively controls the temperature of the sanding belt 46 , keeping it within a suitable temperature range and preventing damage to the paper substrate surface caused by excessive temperature. This reduces the deformation, delamination, or surface quality degradation of the paper substrate caused by overheating of the sanding belt 46 , improves the stability and durability of the sanding belt 46 , extends the service life of the sanding belt 46 , ensures the efficiency and consistency of the roughening process, and thus improves the quality and precision of the paper substrate treatment. When the slider 2 525 moves back and forth, it repeatedly pulls and pushes the two piston rods 541, causing the two piston rods 541 to slide back and forth in the two air cylinders 542 respectively. When the piston rod 541 slides away from the air inlet valve 543, the space between the piston rod 541 and the air inlet valve 543 in the air cylinder 542 becomes larger, and the air pressure becomes lower. At this time, the air inlet valve 543 opens, and the external air enters the air cylinder 542 through the air inlet valve 543. When the piston rod 541 moves closer to the air inlet valve 543 in the air cylinder 542, the air inlet valve 543 is released. When sliding in the opposite direction, the space between the piston rod 541 and the air inlet valve 543 in the air cylinder 542 becomes smaller, the air pressure returns to normal, the air inlet valve 543 closes, and the air entering the air cylinder 542 is squeezed into the heat dissipation shell 531 through the air supply hose 544 and the air outlet valve 545, and blown to the multiple heat dissipation aluminum fins 533, blowing air to the multiple heat dissipation aluminum fins 533 that have absorbed heat, which helps to accelerate the heat dissipation of the multiple heat dissipation aluminum fins 533. The air outlet valve 545 effectively prevents the gas that has entered the heat dissipation shell 531 from flowing back.
