Description

Technical Field

[0001] This utility model relates to the field of cardboard packaging printing technology, and in particular to a wrinkle-preventing and smoothing device for cardboard packaging printing. Background Technology

[0002] The anti-wrinkle smoothing device for cardboard packaging printing is an automated device used to eliminate wrinkles on the surface of cardboard, ensuring that the pattern is clear and undistorted. It is usually equipped with an adjustment system to adapt to cardboard of different thicknesses, improve the packaging yield, and is widely used in the post-printing process.

[0003] Existing anti-wrinkle smoothing devices for carton packaging printing typically use rotating pressure bars to smooth the cardboard. However, due to the simple design of the pressure bar structure, the limited pressure adjustment range, and the lack of a dynamic pressure compensation mechanism, the pressure on the cardboard is low and uneven. Especially when processing thicker or harder cardboard, the pressure bar of traditional devices cannot provide sufficient contact pressure, resulting in poor smoothing effect and leaving fine wrinkles on the cardboard surface, affecting printing quality and packaging appearance.

[0004] Therefore, in view of the problem that the existing anti-wrinkle smoothing devices for carton packaging printing usually use a pressure bar to smooth the cardboard, which results in low pressure and poor smoothing effect, a new anti-wrinkle smoothing device for carton packaging printing can be designed. Utility Model Content

[0005] To overcome the problem that existing anti-wrinkle smoothing devices for cardboard packaging printing typically use a rotating pressure bar to smooth the cardboard, resulting in low pressure and poor smoothing effect.

[0006] The technical solution of this utility model is as follows: a cardboard packaging printing anti-wrinkle smoothing device, including a base; and a second pressure roller. Two supports are installed on the top of the base, and two guide rails are fixed on each of the two supports. A first bearing seat is installed between the corresponding two guide rails, and a first pressure roller is connected between the two first bearing seats. A second bearing seat is also slidably connected between the corresponding two guide rails. A cylinder is installed on the top of each of the two supports, and the output end of the cylinder is connected to the corresponding second bearing seat. The cylinder is used to drive the second bearing seat to move up and down. A second pressure roller is installed between the two second bearing seats. A limit mechanism is provided between the two supports. A drive motor is installed on the top right side of the base, and a reducer is connected to the output end of the drive motor. The output end of the reducer is connected to the right end of the first pressure roller. The drive motor is used to drive the first pressure roller to rotate. A dust removal mechanism is provided on the top of the base.

[0007] Preferably, by setting a cylinder, the second bearing seat can be driven to rise and fall along the guide rail during operation, thereby driving the second pressure roller to rise and fall, thus adjusting the distance between the first and second pressure rollers and realizing pressure adjustment. When the drive motor runs, it drives the first pressure roller to rotate, and the cardboard passes between the first and second pressure rollers, thereby flattening it. This solves the problem that existing anti-wrinkle smoothing devices for carton packaging printing usually use the rotation of pressure rods to smooth the cardboard, which results in low pressure and poor smoothing effect.

[0008] Preferably, the limiting mechanism includes a rotating component and a transmission component, wherein the transmission component is used to drive the rotating component to rotate, and the rotating component is used to position the second pressure roller.

[0009] Preferably, the rotating assembly includes mounting bearings and a rotating shaft; mounting bearings are provided on both brackets, and a rotating shaft is installed between the two mounting bearings.

[0010] Preferably, the transmission assembly includes gears and racks; gears are provided on both the left and right sides of the outer surface of the rotating shaft, and racks are installed on both second bearing seats, with the gears meshing with the racks.

[0011] Preferably, the dust removal mechanism includes a support assembly and a dust blowing assembly, wherein the support assembly is used to mount the dust blowing assembly, and the dust blowing assembly is used to clean the surface of the cardboard.

[0012] Preferably, the support assembly includes columns, mounting plates, and through slots; two columns are installed on the top of the base, and mounting plates are fixed on the two columns, with through slots opened on the top of the mounting plates.

[0013] Preferably, the soot blowing assembly includes a fan and a mounting plate; the fan is installed on the top of the mounting plate, and mounting plates are installed on both the left and right ends of the fan, with the mounting plates fixed to the mounting plate by bolts.

[0014] The beneficial effects of this utility model are:

[0015] By using two pressure rollers working in tandem, the cardboard is evenly flattened using a roller pressing method. The cylinder adjustment mechanism can flexibly control the distance between the two pressure rollers, achieving stepless pressure adjustment. This can meet the high-pressure requirements of thick cardboard while also adapting to the gentle handling of thin cardboard. This dynamic adjustment capability effectively avoids problems such as cardboard crushing or incomplete pressing caused by traditional fixed pressure, enabling cardboard of different materials and thicknesses to achieve ideal flatness. It significantly improves the smoothness and flatness of the cardboard surface and enhances the appearance quality of the finished product. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5 This utility model provides an embodiment of a cardboard packaging printing anti-wrinkle smoothing device, including a base 1; it also includes a second pressure roller 9. Two supports 2 are mounted on the top of the base 1, and two guide rails 3 are fixed on each of the two supports 2. A first bearing seat 4 is installed between the corresponding two guide rails 3, and a first pressure roller 5 is connected between the two first bearing seats 4. A second bearing seat 6 is also slidably connected between the corresponding two guide rails 3. A cylinder 7 is mounted on the top of each of the two supports 2, and the output end of the cylinder 7 is connected to the corresponding second bearing seat 6. The cylinder 7 is used to drive the second bearing seat 6 to move up and down. A second pressure roller 9 is installed between the two second bearing seats 6. A limit mechanism is provided between the two supports 2. A drive motor 10 is installed on the top right side of the base 1. The output end of the drive motor 10 is connected to a reducer 11. The output end of the reducer 11 is connected to the right end of the first pressure roller 5. The drive motor 10 is used to drive the first pressure roller 5 to rotate. A dust removal mechanism is set on the top of the base 1. The second bearing seat 6 is driven by the cylinder 7 to move vertically along the guide rail 3, thereby driving the second pressure roller 9 to achieve lifting and lowering adjustment. This design makes the roller gap between the first pressure roller 5 and the second pressure roller 9 adjustable, thereby achieving precise control of the pressure of the pressing area. When the drive motor 10 is started, the first pressure roller 5 rotates as the active roller. At this time, the paperboard material to be processed is fed into the pressing area formed by the two pressure rollers and is flattened under the action of the rollers.

[0024] Please see Figures 1-3In this embodiment, the limiting mechanism includes a rotating component and a transmission component. The transmission component drives the rotating component to rotate and positions the second pressure roller 9. The rotating component includes a mounting bearing 81 and a rotating shaft 82. Mounting bearings 81 are provided on both brackets 2, and a rotating shaft 82 is installed between the two mounting bearings 81. The transmission component includes a gear 83 and a rack 84. Gears 83 are provided on both the left and right sides of the outer surface of the rotating shaft 82, and racks 84 are installed on both second bearing seats 6. The gears 83 and racks 84 mesh. By setting racks 84 and gears 83, the second bearing seats 6 move synchronously, driving racks 84 to move synchronously. Through meshing with gears 83, racks 84 drive the rotating shaft 82 to rotate in cooperation with the mounting bearings 81, thereby ensuring that the second bearing seats 6 on both sides can rise and fall synchronously.

[0025] Please see Figure 1 , Figure 4 and Figure 5 In this embodiment, the dust removal mechanism includes a support assembly and a dust blowing assembly. The support assembly is used to install the dust blowing assembly, which is used to clean the surface of the cardboard. The support assembly includes a column 121, a mounting plate 122, and a through groove 123. Two columns 121 are installed on the top of the base 1, and mounting plates 122 are fixed on the two columns 121. The top of the mounting plate 122 is provided with a through groove 123. The columns 121 are used to position and install the mounting plate 122. The dust blowing assembly includes a fan 124 and a fixing plate 125. The fan 124 is provided on the top of the mounting plate 122, and fixing plates 125 are provided on both the left and right ends of the fan 124. The fixing plates 125 are fixed to the mounting plate 122 with bolts. By providing the fan 124, a strong wind can be blown out during operation. The strong wind passes through the through groove 123 and blows onto the surface of the cardboard, blowing off the dust on the surface of the cardboard.

[0026] During operation, cylinder 7 pushes the second bearing seat 6 connected to it to move up and down along the guide rail 3 on the bracket 2, thereby driving the second pressure roller 9 to rise and fall, thus adjusting the distance between the second pressure roller 9 and the first pressure roller 5 to adapt to different thicknesses of cardboard and control the flattening pressure. During this process, the rack 84 on the second bearing seat 6 moves accordingly, driving the gear 83 meshing with it to rotate. The gear 83 is fixed on the rotating shaft 82 that passes through the bearing 81 on the bracket 2, thus ensuring that the second bearing seats 6 and the second pressure roller 9 on both sides rise and fall synchronously and remain horizontal. After the drive motor 10 starts, it drives the first pressure roller 5 to rotate through the reducer 11. The cardboard passes between the first pressure roller 5 and the second pressure roller 9 and is flattened under the pressure applied by both, effectively smoothing out wrinkles. At the same time, the fan 124 on the top of the mounting plate 122 supported by the column 121 on the base 1 starts. The strong wind generated by the fan passes down through the through groove 123 on the mounting plate 122 and blows on the surface of the cardboard passing below, blowing off the dust attached to the cardboard and completing the dust removal operation.

[0027] Through the above steps, by using cylinder 7 as a power source, the second bearing seat 6 is pushed to move up and down along guide rail 3, thereby adjusting the height position of the second pressure roller 9. By changing the gap between the second pressure roller 9 and the first pressure roller 5, the pressure of the pressing area can be flexibly adjusted. When the drive motor 10 is working, it drives the first pressure roller 5 to rotate. During the conveying process, the cardboard passes through the squeezing area formed by the two pressure rollers and is flattened under pressure. This solves the problem that existing anti-wrinkle smoothing devices for carton packaging printing usually use pressure rod rotation to smooth the cardboard, which results in low pressure and poor smoothing effect.
