Description

Technical Field

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

[0002] Laser cardboard film is one of the important base materials for making cigarette boxes. Laser cardboard film lamination means transferring the holographic pattern on the laser film to the base material of the cigarette box (such as white cardboard or gray-backed white board paper) through heating and pressure, so that it has the functions of glare, anti-counterfeiting and decoration.

[0003] In cigarette box production, the coating process in laser cardboard film lamination refers to uniformly coating a layer of paint onto the surface of the substrate to facilitate the subsequent lamination process. The main target of the coating process is usually the surface of the paper substrate, that is, the part that carries the laser film.

[0004] Before the laser cardboard film is laminated in the production of cigarette boxes, the coating process on the paper substrate can easily result in the coating failing to adhere firmly to the paper substrate, leading to peeling and detachment. This prevents the coated paper substrate from fully bonding with the laser film, thus negatively impacting the subsequent laser cardboard film lamination process. Summary of the Invention

[0010] Preferably, the cleaning component includes a reciprocating screw rotatably connected to the inner wall of the outer casing, a pulley assembly fixedly connected to the outer wall of the reciprocating screw and the outer wall of the rotating shaft, a helical gear symmetrically fixedly connected to the outer wall of the reciprocating screw, a sliding outer casing threadedly connected to the outer wall of the reciprocating screw, limit rods symmetrically fixedly connected to the inner wall of the outer casing, a cleaning rubber block slidably connected to the inner wall of the sliding outer casing and the outer walls of the two limit rods.

[0011] Preferably, the cleaning component also includes several springs two, each fixedly connected to the bottom of the cleaning rubber block, with the outer wall of each spring two fixedly connected to the inner wall of the sliding housing.

[0012] Preferably, the brush assembly includes two fixed blocks 1 that are symmetrically distributed and fixedly connected to the outer wall of the outer casing 1. Two fixed blocks 2 are symmetrically fixedly connected to the outer wall of the outer casing 1. Two reciprocating screws 2 are rotatably connected to the inner walls of the fixed blocks 1 and 2 on the same side. Two helical gears 2 are fixedly connected to the outer walls of the two reciprocating screws 2. The outer walls of the helical gears 2 on the same side are meshed with the outer walls of the helical gears 1. Two sliders 2 are threadedly connected to the outer walls of the two reciprocating screws 2. The outer walls of the two sliders 2 are slidably connected to the inner walls of the outer casing 1. The inner walls of the two sliders 2 are rotatably connected to the brush.

[0013] Preferably, the brush assembly further includes two racks that are symmetrically distributed and fixedly connected to the inner wall of the outer casing, and a gear is symmetrically rotatably connected to the outer wall of the brush, with the outer wall of the gear on the same side meshing with the outer wall of the rack.

[0014] Preferably, the heat absorption component includes a heat dissipation shell fixedly connected to an inner wall of the outer shell, a rotating shaft rotatably connected to the outer wall of the heat dissipation shell, heat-conducting plates symmetrically fixedly connected to the inner wall of the heat dissipation shell, and a plurality of heat dissipation aluminum fins fixedly connected to the outer walls of the two heat-conducting plates.

[0015] Preferably, the air blowing assembly includes an air cylinder fixedly connected to the inner wall of the outer casing, 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 a side slider, an air inlet valve being connected through the outer wall of the air cylinder, a through air delivery hose being fixedly connected to both the outer wall of the air cylinder and the outer wall of the heat dissipation outer casing, and an air outlet valve being connected through the outer wall of the heat dissipation outer casing.

[0016] 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: This invention uses a sanding belt that rotates continuously to polish the surface of a paper substrate. This roughens the surface of the paper substrate used for laser card film molding before the coating process, allowing the coating to adhere more firmly to the paper substrate. This increases the contact area between the coating and the paper substrate, improves the coating adhesion, and reduces the possibility of coating peeling or detachment after the paper substrate is coated. This prevents such coating peeling or detachment from negatively impacting the subsequent laser card film molding process.

[0017] The pulley assembly, reciprocating screw, and cleaning rubber block of this invention, while the sanding belt continuously reciprocates to roughen the surface of the paper substrate, allow the cleaning rubber block to reciprocate to clean the dirt adhering to the surface of the sanding belt generated during the roughening of the paper substrate surface. This effectively removes the dirt attached to the surface of the sanding belt, ensuring that the sanding belt always maintains its optimal working condition and avoiding problems such as uneven surface treatment or inconsistent roughness of the paper substrate caused by dirt accumulation and blockage on the surface of the sanding belt.

[0018] The helical gear I, helical gear II, reciprocating screw I, and brush configured in this invention clean the dirt on the surface of the sanding belt while the cleaning rubber block reciprocates. Simultaneously, the brush reciprocates in coordination with the reciprocating rotation of the sanding belt, cleaning larger particles of dirt or impurities on the surface of the sanding belt before cleaning the rubber block. This significantly reduces the dirt load on the surface of the sanding belt when the cleaning rubber block is in direct contact with it, improving the cleaning effect. At the same time, it avoids direct contact between larger dirt particles and the surface of the cleaning rubber block, reducing wear and extending its service life.

[0019] The heat-conducting plate and heat-dissipating aluminum fins in this invention absorb and dissipate the heat generated during the continuous rotation of the sanding belt to roughen the surface of the paper substrate, keeping the sanding belt within a suitable temperature range and preventing damage to the paper substrate surface due to excessive temperature. This reduces the potential problems of deformation, delamination, or surface quality degradation of the paper substrate caused by overheating of the sanding belt. The piston rod, air cylinder, air inlet valve, and air outlet valve blow air onto several heat-absorbing aluminum fins, which helps to accelerate the dissipation of heat from the aluminum fins.

[0022] 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.

[0023] Example 1, as Figures 1-3 As shown, a laser cardboard film pressing device includes a support frame 1, a housing 2 fixedly connected to the top of the support frame 1, a motor 3 fixedly connected to the outer wall of the housing 2, a processing mechanism 4 and a cleaning mechanism 5 provided on the inner wall of the housing 2. The processing mechanism 4 includes a rotating shaft 41 rotatably connected to the inner wall of the housing 2, the outer wall of the rotating shaft 41 being fixedly connected to the output end of the motor 3, rubber wheels 42 symmetrically rotatably connected to the inner wall of the housing 2, sanding belt 46 wound on the outer walls of the two rubber wheels 42, transition rollers 43 symmetrically rotatably connected to the inner wall of the housing 2, gears 44 fixedly connected to the outer walls of the rotating shaft 41, the two rubber wheels 42, and the two transition rollers 43, toothed belts 45 meshing on the outer walls of the five gears 44, a limiting housing 47 fixedly connected to the outer wall of the housing 2, a plurality of limiting components 48 symmetrically arranged in a linear array on the inner wall of the limiting housing 47, and pressure roller components 49 symmetrically arranged on the top of the housing 2.

[0024] The aforementioned motor 3 is a servo motor, which is a mature technology in the prior art. This invention only borrows its function of controlling the rotation speed, number of rotations, and start / stop at any time. Its structure and working principle will not be elaborated here. Both rubber wheels 42 mentioned above are abrasive belt rubber wheels, which are usually used in conjunction with abrasive belt 46. Their elasticity helps abrasive belt 46 to apply pressure evenly, reducing damage to the workpiece during processing. By applying a certain pressure, abrasive belt 46 is brought into contact with the workpiece surface, thereby effectively removing material. This is a mature technical means in the prior art. The structure and working principle of this invention will not be elaborated further here. The meshing connections between the five gears 44 and the toothed belt 45 all meet the required wrap angle for transmission. In a specific implementation of the present invention, the device is placed in a suitable position for processing cigarette box paper substrate and connected to other related production lines for conveying cigarette box paper substrate and laser cardboard film pressing. During the continuous conveying of the paper substrate by the paper substrate conveying equipment, the paper substrate is placed between two pressure roller assemblies 49. At this time, the continuously moving paper substrate is in a state of appropriate contact between the side that needs to be roughened and the surface of the sand belt 46. The motor 3 is turned on, which drives the rotating shaft 41 to rotate, thereby driving the gear 44 mounted on the rotating shaft 41 to rotate, which in turn drives the toothed belt 45 to rotate, which in turn drives 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 rotates continuously and reciprocally, polishing the surface of the paper substrate. This roughens the surface of the paper substrate used for laser card film molding before the coating process, so that the coating can adhere more firmly to the paper substrate. This increases the contact area between the coating and the paper substrate, improves the adhesion of the coating, and reduces the phenomenon of coating peeling or detachment after the paper substrate is coated. This prevents the coating peeling or detachment from having an adverse effect on the subsequent laser card film molding process.

[0025] Example 2, as Figures 4-6 As shown, the limiting component 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 all fixedly connected to the inner wall of the limiting housing 47. A spring 483 is sleeved on the outer wall of the plurality of telescopic rods 482. The outer wall of the plurality of springs 483 is fixedly connected to the top of the roller 481. The outer wall of the plurality of springs 483 is fixedly connected to the inner wall of the limiting housing 47. The pressure roller assembly 49 includes two mounting brackets 491 that are symmetrically distributed and fixedly connected to the top of the outer casing 2. Slider 492 is slidably connected to the inner wall of each mounting bracket 491. Pressure roller 493 is rotatably connected to the outer wall of each slider 492. Turntable screws 494 are threadedly connected to the inner wall of each mounting bracket 491. The bottom of the turntable screws 494 on the same side is rotatably connected to the top of the slider 492.

[0026] In a specific implementation of this invention, before the processing mechanism 4 roughens the surface of the paper substrate, the paper substrate is passed sequentially between the same-side transition roller 43 and the pressure roller 493. 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 same-side transition roller 43 and the pressure roller 493 is adjusted to a suitable distance for the conveying of the paper substrate and the production line. The setting of the two pressure roller assemblies 49 allows the sanding belt 46 to reciprocate and roughen the surface of the paper substrate without affecting the continuous conveying of the paper substrate. This restricts the movement of the paper substrate and ensures that the position of the paper substrate on the sanding belt 46 is stable, thereby ensuring the uniformity of the roughening treatment and preventing the paper substrate from shifting or wrinkling during the processing. This ensures that each part receives the same roughening treatment. Several rollers 481 are in contact with the toothed belt 45. When the five gears 44 rotate and drive the toothed belt 45 to rotate back and forth, several rollers 481 all play a limiting role on the toothed belt 45. Several telescopic rods 482 provide vertical support to several springs 483.

[0027] Example 3, as Figures 7-14 As shown, the cleaning mechanism 5 includes a cleaning component 51 disposed on the inner wall of the outer casing 2, a brush component 52 disposed on the inner wall of the outer casing 2, a heat absorption component 53 disposed on the inner wall of the outer casing 2, and air blowing components 54 symmetrically disposed on the inner wall of the outer casing 2. The cleaning component 51 includes a reciprocating screw 512 rotatably connected to the inner wall of the outer casing 2, a pulley assembly 511 fixedly connected to the outer wall of the reciprocating screw 512 and the outer wall of the rotating shaft 41, a helical gear 513 symmetrically fixedly connected to the outer wall of the reciprocating screw 512, a sliding outer casing 514 threadedly connected to the outer wall of the reciprocating screw 512, limit rods 515 symmetrically fixedly connected to the inner wall of the outer casing 2, a sliding connection between the inner wall of the sliding outer casing 514 and the outer walls of the two limit rods 515, and a cleaning rubber block 516 slidably connected to the inner wall of the sliding outer casing 514. The cleaning component 51 also includes several springs 517 that are fixedly connected to the bottom of the cleaning rubber block 516, and the outer wall of the several springs 517 is fixedly connected to the inner wall of the sliding housing 514. The brush assembly 52 includes two fixing blocks 521 that are symmetrically distributed and fixedly connected to the outer wall of the outer shell 2. Fixing blocks 522 are symmetrically fixedly connected to the outer wall of the outer shell 2. Reciprocating screws 524 are rotatably connected to the inner walls of fixing blocks 521 and 522 on the same side. Helical gears 523 are fixedly connected to the outer walls of the two reciprocating screws 524. The outer walls of the helical gears 523 on the same side are meshed with the outer walls of the helical gears 513. Slider 525 is threadedly connected to the outer walls of the two reciprocating screws 524. The outer walls of the two sliders 525 are slidably connected to the inner wall of the outer shell 2. A brush 526 is rotatably connected to the inner walls of the two sliders 525. The brush assembly 52 also includes two racks 528 that are symmetrically distributed and fixedly connected to the inner wall of the outer casing 2. A gear 527 is symmetrically rotatably connected to the outer wall of the brush 526. The outer wall of the gear 527 on the same side is meshed with the outer wall of the rack 528. The heat absorption component 53 includes a heat dissipation shell 531 fixedly connected to the inner wall of the outer shell 2, a rotating shaft 41 rotatably connected to the inner wall of the heat dissipation shell 531 at its outer wall, heat conduction plates 532 symmetrically fixedly connected to the inner wall of the heat dissipation shell 531, and several heat dissipation aluminum fins 533 fixedly connected to the outer walls of the two heat conduction plates 532. The air blowing assembly 54 includes an air cylinder 542 fixedly connected to the inner wall of the outer casing 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 525 on one side. An air inlet valve 543 is connected through the outer wall of the air cylinder 542. A through air delivery hose 544 is fixedly connected to both the outer wall of the air cylinder 542 and the outer wall of the heat dissipation outer casing 531. An air outlet valve 545 is connected through the outer wall of the heat dissipation outer casing 531.

[0028] The aforementioned air intake valve 543 and air outlet valve 545 are both one-way valves, which are mature technologies in the prior art. The cooperation between the two and the piston rod 541 allows the air blowing assembly 54 to efficiently and smoothly complete the intake and exhaust of gas. These are mature technologies in the prior art, and their structure and working principle will not be elaborated further in this solution. The aforementioned cleaning rubber block 516 is a sanding belt cleaning block, a tool used to clean the surface of sanding belts. It is a mature technology in the existing technology, and its structure and working principle will not be elaborated further in this solution. In a specific implementation of this invention, when the motor 3 is turned on to drive the rotating shaft 41 to rotate, thereby causing the sanding belt 46 to reciprocate to roughen the surface of the paper substrate, the pulley group 511 drives the reciprocating screw 512 to rotate, thereby driving the sliding housing 514 to reciprocate, thereby driving the cleaning rubber block 516 to reciprocate, cleaning the dirt adhering to the surface of the sanding belt 46 generated during the roughening of the paper substrate surface, thereby effectively removing the dirt adhering 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 the accumulation and blockage of dirt on the surface of the sanding belt 46; Several springs 517 enable the cleaning rubber block 516 to automatically adjust the contact pressure on the sanding belt 46 according to the unevenness of the sanding belt 46 surface, the amount of dirt accumulation, and the wear that occurs during the continuous cleaning of the dirt on the sanding belt 46 surface, so as to ensure 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 512 drives the two helical gears 513 to rotate, which in turn drives the two helical gears 523 to rotate, which in turn drives the two reciprocating screws 524 to rotate, which in turn drives the two sliders 525 to reciprocate, which in turn drives the brush 526 to reciprocate, thus 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 ensures that the area on the surface of the sanding belt 46 that needs to be cleaned passes through the brush 526 first. This allows the brush 526 to clean the larger particles of dirt or impurities on the surface of the sanding belt 46 before cleaning the rubber block 516. This significantly reduces the dirt burden when the cleaning rubber block 516 is in direct contact with the surface of the sanding belt 46, improves the cleaning effect on the surface of the sanding belt 46, and at the same time avoids larger dirt particles from directly contacting the surface of the cleaning rubber block 516, reducing the wear of the cleaning rubber block 516 and extending its service life. Both sliders 525 reciprocate, which in turn drives both gears 527 to reciprocate, meshing with the rack 528 on the same side. This causes the brush 526 to rotate while cleaning the surface of the sanding belt 46, which helps to improve cleaning efficiency, evenly distribute the wear of the bristles, avoid excessive use of the brush 526 in some areas, and extend the service life of the brush 526. During the continuous rotation of the sanding belt 46 to roughen the surface of the paper substrate, frictional heat is generated. The sanding belt 46 is in contact with both heat-conducting plates 532 during its reciprocating rotation. Both heat-conducting plates 532 absorb the heat generated by the sanding belt 46 and transfer it to several heat dissipation 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 surface of the paper substrate due to excessive temperature. It reduces the possibility of deformation, delamination, or surface quality degradation of the paper substrate due to overheating of the sanding belt 46, improves the stability and durability of the sanding belt 46, extends its service life, ensures the efficiency and consistency of the roughening process, and thus improves the quality and precision of the paper substrate treatment. When slider 2 525 reciprocates, it repeatedly pulls and pushes the two piston rods 541, causing them to slide back and forth within the two air cylinders 542. As the piston rods 541 slide away from the air inlet valve 543, the space between them and the valve increases, and the air pressure decreases. At this point, the air inlet valve 543 opens, allowing outside air to enter the air cylinder 542. As the piston rods 541 move closer to the air inlet valve 543 within the air cylinder 542... When the direction is slidable, the space between the piston rod 541 and the air inlet valve 543 inside 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 delivery hose 544 and the air outlet valve 545, and blown towards several heat dissipation aluminum fins 533. Blowing air onto several heat dissipation aluminum fins 533 that have absorbed heat helps to accelerate the dissipation of heat from several heat dissipation aluminum fins 533. The air outlet valve 545 effectively prevents the gas entering the heat dissipation shell 531 from flowing back.
