[0001] This utility model relates to the field of laminating machine technology, and in particular to a digital printing laminating machine. Background Technology

[0002] A printing paper laminating machine is a device used to coat the surface of printed materials with a thin film, designed to improve the durability, gloss, and visual appeal of the printed materials.

[0003] Patent CN217968922U discloses a laminating device for printing paper. It includes two housings, with a motor housed within the inner cavity of each housing. The output end of the motor is connected to a rotating shaft. A first belt and a second belt are fitted onto the circumferential surface of the rotating shaft. The other end of the first belt is fitted onto one end of the circumferential surface of a first roller, and the first belt drives the first roller to rotate. The other end of the second belt is fitted onto one end of the circumferential surface of the rotating shaft, and the second belt also drives the rotating shaft to rotate. Conveyor belts are fitted onto the circumferential surfaces of the two rotating shafts. A groove is formed within the inner cavity of each housing, and a support plate is slidably inserted into the inner cavity of the groove. When using this patent for lamination, rotating the rotating rod drives the sliding rod, connecting frame, support plate, and second roller to slide, thereby limiting the printing paper before lamination. However, since the aforementioned patent is of a fixed size, when laminating larger sizes of printing paper, a larger laminating machine needs to be purchased, increasing equipment procurement costs and occupying more production workshop space.

[0004] Therefore, there is a need for a digital printing laminating machine that integrates multiple sizes of laminating and transport mechanisms. Utility Model Content

[0006] To address the aforementioned problems, this utility model adopts the following technical solution: A digital printing laminating machine includes a base plate, a protective shell, a flip-up door, and a handle. The protective shell is fixedly attached to the base plate, and the flip-up door is rotatably mounted on the protective shell. A handle is fixedly attached to the flip-up door. The machine also includes fixed seats, fixed rings, a take-up drum, a first transmission assembly, a first limiting roller, a second limiting roller, a first spur gear set, a second transmission assembly, a first pressing roller, a third transmission assembly, a second pressing roller, a first drive motor, a hot press, and a radiator. Four fixed seats are fixedly attached to the base plate, and fixed rings are mounted on the fixed seats. A take-up drum is rotatably mounted between two fixed seats. The first transmission assembly is mounted on each of the three fixed rings, and the first transmission assembly contacts the adjacent take-up drum. A first limiting roller is rotatably mounted between two fixed seats. A second limiting roller is rotatably arranged between two fixed seats. A first limiting roller is located above the second limiting roller. A spur gear set is arranged between the first and second limiting rollers. A second transmission assembly is installed on the fixed seat and contacts the adjacent first limiting roller. A first pressing roller is rotatably arranged between two fixed seats. A second pressing roller is rotatably arranged between two fixed seats and above the first pressing roller. The components of the second pressing roller are identical to those of the first pressing roller. A third transmission assembly is installed on one of the fixed seats. The transmission wheel of the third transmission assembly contacts the first pressing roller. A first drive motor is installed on the base plate, and the output shaft of the first drive motor is connected to the second pressing roller. A hot press is installed between the two fixed seats and between the first pressing roller and the second limiting roller. A radiator is installed on the base plate.

[0007] As an improvement to the above solution, it also includes a support plate, a pressure plate, and a return spring. Two support plates are fixedly connected to the fixed base, and pressure plates are slidably arranged on the two corresponding support plates. The pressure plates are located below the adjacent winding drums, and two return springs are sleeved on the pressure plates. The two ends of the return springs are connected to the support plate and the pressure plate, respectively.

[0008] As an improvement to the above scheme, it also includes a second drive motor, a first drive roller, a second drive roller, an anti-roll plate, and a second spur gear set. Multiple second drive motors are mounted on the base plate. The output shaft of the second drive motor is connected to the first drive roller via a coupling. Multiple second drive rollers are rotatably mounted on multiple fixed seats. The second drive rollers are located above the first drive rollers. Three anti-roll plates are fixedly connected between the multiple second drive rollers. The anti-roll plates are located between two fixed seats. A second spur gear set is provided between the first drive roller and the second drive roller.

[0009] As an improvement to the above solution, a dust filter is also included, with three dust filters installed on the radiator.

[0010] As an improvement to the above solution, an anti-slip sleeve is also included, with the handle covered with an anti-slip sleeve.

[0011] As an improvement to the above solution, a bellows is also included, with a bellows installed between the support plate and the pressure plate, and a return spring located inside the bellows.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By using a transport mechanism consisting of three sets of first drive motors of different sizes, second pressing roller, first pressing roller, first limiting roller and second limiting roller, it is possible to laminate printing paper of different sizes, and it is possible to use a transport mechanism of the corresponding size without adjusting it, thereby reducing adjustment time and improving work efficiency.

[0013] 2. The pressure plate holds the film roll in place, causing the return spring to deform and preventing the film roll from unraveling during lamination, thus preventing the machine from jamming.

[0014] 3. By passing the printing paper and film between the anti-roll plate and the first transmission roller, the second drive motor is started. The output shaft of the second drive motor drives the first transmission roller to rotate. The first transmission roller drives the second transmission roller to rotate through the second spur gear set, thereby flattening the film and preventing the film from being rolled between the first pressing roller and the second limiting roller.

The device also includes fixed seats 50, fixed rings 5, a winding drum 6, a first transmission assembly 7, a first limiting roller 8, a second limiting roller 9, a first spur gear set 10, a second transmission assembly 11, a first pressing roller 12, a third transmission assembly 13, a second pressing roller 14, a first drive motor 15, a hot press 16, and a radiator 17. Four fixed seats 50 are welded onto the base plate 1. Fixed rings 5 ​​are mounted on the top of each fixed seat 50. A rotatable mechanism is provided between two fixed seats 50. A take-up drum 6 is provided, and a retaining ring 5 secures the end of the take-up drum 6. The lengths of the three take-up drums 6 increase from shortest to longest from left to right. A first transmission assembly 7 is mounted on the top of each of the three retaining rings 5 ​​from left to right. The first transmission assembly 7 consists of a fixed plate, a motor, and a transmission wheel. The transmission wheel of the first transmission assembly 7 contacts the left end of the nearest take-up drum 6. A limiting roller 1 rotatably is positioned between the middle of two fixed seats 50, and a limiting roller 2 rotatably is also positioned between the middle of two fixed seats 50. The limiting roller 1 8 is located above the limiting roller 2 9. A spur gear set 10 is positioned between the right ends of the limiting roller 1 8 and the limiting roller 2 9. The spur gear set 10 consists of two meshing gears. The top of the fixed seat 50 is equipped with... The system is equipped with a second transmission assembly 11, which has the same components as the first transmission assembly 7. The transmission wheel of the second transmission assembly 11 contacts the left end of the adjacent limit roller 8. A pressure roller 12 is rotatably arranged between the lower parts of the two fixed seats 50. The pressure roller 12 consists of a rotating shaft and three pressure rollers. The three pressure rollers are the same length as the adjacent take-up drum 6 and are located between the two fixed seats 50. A second pressure roller 14 is rotatably arranged between the lower parts of the two fixed seats 50, with the first pressure roller 12 located above it. The components of the second pressure roller 14 are the same as those of the first pressure roller 12. A third transmission assembly 13 is arranged on the left fixed seat 50. The third transmission assembly 13 is connected to the second transmission assembly 7. The components of component 11 are identical. The transmission wheel of the third transmission component 13 is in contact with the first pressing roller 12. The first drive motor 15 is installed on the upper left side of the base plate 1 by bolt connection. The output shaft of the first drive motor 15 is connected to the rotating shaft of the second pressing roller 14. The hot press 16 is installed between the two fixed seats 50 by bolt connection. The hot press 16 is located between the first pressing roller 12 and the second limiting roller 9. The radiator 17 is installed at the rear of the base plate 1 by bolt connection. The radiator 17 consists of three electric fan components. The winding drum 6, the first limiting roller 8, the second limiting roller 9, the first pressing roller 12 and the second pressing roller 14 of the same length form a transportation mechanism. The three transportation mechanisms form a complete transportation system.

[0027] See Figure 2As shown, it also includes a dust filter 26, and three dust filters 26 are installed on the radiator 17.

[0028] See Figure 1 As shown, it also includes an anti-slip sleeve 27, which is fitted onto the handle 4.

[0029] Before laminating the printing paper, place the printing paper between the second pressing roller 14 and the first pressing roller 12, remove the retaining ring 5, then put the film roll onto the take-up drum 6, and then replace the retaining ring 5. Pull the film through the first limiting roller 8 and the second limiting roller 9, and then pass the film through the second pressing roller 14 and the first pressing roller 12 to bond the printing paper with the film. When lamination is required, start the first drive motor 15, causing the output shaft of the first drive motor 15 to drive the second pressing roller 14 to rotate, moving the printing paper backward. The printing paper squeezes the first pressing roller 12 to rotate, causing the second pressing roller 14 and the first pressing roller 12 to transport the printing paper. At the same time, the motor on the first transmission assembly 7 drives the transmission wheel on the output shaft to rotate, causing the first transmission assembly 7 to drive the take-up drum 6 to rotate, and the second transmission assembly 11 drives the first limiting roller 8 to rotate, causing the first limiting roller 8 to drive the second limiting roller 9 to rotate through the spur gear set 10, thereby transporting the film. Then, the film is pressed by the first pressing roller 12 and the second pressing roller 14. During pressing, the hot press 16 dissipates heat, causing the film to stick to the printing paper. This is the lamination operation. The laminated printing paper is finally discharged from the opening of the protective shell 2. The radiator 17 cools the laminated printing paper. The conveying mechanism, composed of three sets of first drive motors 15, second pressing roller 14, first pressing roller 12, first limiting roller 8 and second limiting roller 9 of different sizes, can laminate printing paper of different sizes. It can use the corresponding size conveying mechanism without adjustment, reducing adjustment time and improving work efficiency. The dustproof net 26 is used to protect the electric fan assembly on the nearby radiator 17. When the lamination equipment is not needed, the flip door 3 can be turned by the handle 4 to protect the lamination equipment. The anti-slip sleeve 27 increases the friction between the worker's hand and the handle 4, making it easier for the worker to pull the handle 4.

[0030] Example 2: Based on Example 1, refer to Figure 5 and Figure 7 As shown, it also includes a support plate 18, a pressure plate 19, and a return spring 20. The support plate 18 is welded to both the left and right sides of the front part of the fixed base 50. The pressure plate 19 is slidably mounted on the two corresponding support plates 18. The pressure plate 19 is located below the adjacent winding drum 6. Two return springs 20 are sleeved on the pressure plate 19. The two ends of the return spring 20 are connected to the support plate 18 and the pressure plate 19, respectively.

[0031] See Figure 7As shown, it also includes a bellows 28, which is provided between the support plate 18 and the pressure plate 19, and the return spring 20 is located inside the bellows 28.

[0032] When the film roll is placed on the take-up drum 6, the pressure plate 19 holds the film roll in place, and the return spring 20 deforms accordingly, thus preventing the film roll from unraveling during the coating process and preventing the machine from getting stuck. The bellows 28 is used to protect the return spring 20.

[0033] See Figure 4 and Figure 6 As shown, it also includes a second drive motor 21, a first transmission roller 22, a second transmission roller 23, an anti-roll plate 24, and a second spur gear set 25. Four second drive motors 21 are evenly spaced on the upper left side of the base plate 1 and connected by bolts. The output shaft of the second drive motor 21 is connected to the first transmission roller 22 via a coupling. Four second transmission rollers 23 are evenly spaced and rotatably arranged on the lower part of the four fixed seats 50. The second transmission rollers 23 are located above the first transmission roller 22. Three anti-roll plates 24 are fixedly connected between the four second transmission rollers 23. The anti-roll plates 24 are located between two fixed seats 50 and have the same length as the adjacent fixed seats 50. A second spur gear set 25 is arranged between the first transmission roller 22 and the second transmission roller 23. The components of the second gear set are the same as those of the first spur gear set 10, and the two gears of the second gear set are meshed.

[0034] During lamination, the printing paper and film are passed between the anti-roll plate 24 and the first drive roller 22, and then the second drive motor 21 is started. The output shaft of the second drive motor 21 drives the first drive roller 22 to rotate. The first drive roller 22 drives the second drive roller 23 to rotate through the second spur gear set 25, thereby flattening the film and preventing the film from being rolled between the first pressing roller 12 and the second limiting roller 9.
