Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] In one embodiment, refer to Figures 1 to 9A conveying device for a carton printing machine includes a frame 1. A printing machine body 4 is mounted on the top of the frame 1 via a mounting bracket 3. A controller 2 is located on one side of the mounting bracket 3. A conveying mechanism 6 is located inside the frame 1 for conveying cartons to be printed. The conveying mechanism 6 includes conveyor belts 62 spaced apart. Side limiting mechanisms 5 are located on both inner walls of the frame 1 for adjusting the position of the conveyed cartons on both sides. An adjusting mechanism 8 is located inside the frame 1, and the adjusting mechanism 8 includes components mounted on the frame. 1. An internal fixed base 81 is provided. A telescopic component 82 is installed on the top of the fixed base 81. A lifting housing 83 is installed at one end of the piston rod of the telescopic component 82. An adjustment component 9 and an adjustment component 10 are provided on the lifting housing 83 for adjusting the position of the carton moved to the bottom of the printing machine body 4. The adjustment component 9 includes two horizontally penetrating movable rods 96 on the lifting housing 83. A movable seat 92 is provided at one end of the movable rod 96. Two storage slots 910 are opened inside the movable seat 92. An extension rod 91 is spring-loaded inside the storage slot 910. A pressure sensor 99 is installed at one end of the extension rod 91 that extends into the storage slot 910. A limit plate 93 is installed at the end of the movable rod 96 away from the movable seat 92. A telescopic component 95 is provided on the side of the limit plate 93. The adjustment assembly 10 includes two horizontally penetrating movable rods 103 on the lifting housing 83. A movable seat 105 is provided at one end of each movable rod 103. Two vertically positioned components are installed on the top of the movable seat 105. The extension rod 2 104; the end of the movable rod 2 103 away from the movable seat 2 105 is provided with a limiting plate 2 101, and the side of the limiting plate 2 101 is provided with a telescopic component 4 102; the top positions of the extension rod 1 91 and the extension rod 2 104 correspond to the gap positions between two adjacent conveyor belts 62, and pressure sensor 2 94 and pressure sensor 4 106 are respectively installed on the opposite side of the extension rod 1 91 and the extension rod 2 104; the inner wall of the mounting frame 3 is provided with a laser detection component 7 for monitoring the position of the carton.

[0028] The cardboard box to be printed is placed on the conveyor belt 62. As the conveyor belt 62 moves the cardboard box horizontally, the side limiting mechanism 5 adjusts the position of the left and right sides of the cardboard box to ensure that the cardboard box is in the middle position of the frame 1. When the laser detection component 7 detects that the cardboard box has moved to the bottom of the mounting frame 3, the controller 2 controls the telescopic component 82 to open. The telescopic component 82 pushes the lifting housing 83 upward. At this time, the extension rod 104 extends through the gap between the conveyor belts 62 to the top of the conveyor belt 62. The extension rod 104 is located on the forward side of the cardboard box. As the cardboard box moves horizontally... When the pressure sensor 106 detects the pressure exerted by the cardboard box on the extension rod 104, the telescopic component 102 is activated. The telescopic component 102 pushes the adjusting seat 105 to maintain its horizontal position, ensuring the pressure value detected by the pressure sensor 106 remains within a preset range. At this time, the extension rod 91 abuts against the bottom of the cardboard box. Under the pressure from the bottom of the cardboard box, the extension rod 91 moves downward relative to the adjusting seat 92, compressing the spring and the pressure sensor 99, which detects the pressure value. When the cardboard box moves between the extension rod 91 and the extension rod 104, the extension rod 91... 91 returns to its original position under the action of the spring and extends to the top of the conveyor belt 62. The pressure sensor 399 detects a pressure value of zero, and the controller 2 controls the conveyor belt 62 to stop conveying. At this time, the carton is located between extension rod 191 and extension rod 204. Pressure sensor 294 detects the pressure between the carton and extension rod 191, opening the telescopic component 395. Telescopic component 395 and telescopic component 4102 respectively push the horizontal position of adjusting movable seat 192 and movable seat 2105, thereby moving the carton back and forth within the frame 1 until pressure sensor 294 and pressure sensor 399 are at zero. If the pressure values ​​detected by sensor 4 106 are the same, it means that the carton is centered at the bottom of the printing press body 4. The front and back positions of the carton are adjusted by moving extension rod 1 91 and extension rod 2 104, and the left and right positions of the carton are adjusted by the side limiting mechanism 5. This ensures that the carton is centered at the bottom of the printing press body 4 during printing, thus ensuring that the printing press body 4 can print at the top center of the carton regardless of its size. This results in good printing quality and allows for adaptive adjustment when printing cartons of different sizes, making it convenient and efficient.

[0029] In a preferred embodiment of the present invention, the conveying mechanism 6 includes a conveying roller 64 movably installed in the frame 1. The conveying roller 64 has spaced mounting grooves 63 on its circumference. The conveyor belt 62 is fitted into the mounting grooves 63. A second driving component 61 for driving the conveying roller 64 to rotate is provided on one side wall of the frame 1. The second driving component 61 drives the conveying roller 64 and the conveyor belt 62 to rotate, thereby conveying the carton.

[0030] In a preferred embodiment of the present invention, the lifting housing 83 has through holes 108 on both sides, and the movable rod 103 is disposed inside the through holes 108; the lifting housing 83 has through holes 98 on both sides, and the movable rod 96 is disposed inside the through holes 98.

[0031] As a preferred embodiment of the present invention, the side limiting mechanism 5 includes a telescopic component 54 installed on the inner wall of the frame 1. A side limiting plate 51 is installed at one end of the piston rod of the telescopic component 54. The end of the side limiting plate 51 near the carton loading is an arc-shaped structure.

[0032] In a preferred embodiment of the present invention, the side limit plate 51 has spaced mounting openings 56 on its side, and a drive roller 52 and a driven roller 53 are movably mounted inside the mounting openings 56. The side limit plate 51 is provided with a drive component 57 for driving the driven roller 53 and the drive roller 52 to rotate.

[0033] In a preferred embodiment of the present invention, the drive roller 52 is located at the end of the side limiting plate 51 near the carton feeding end. A pressure sensor 55 is provided on the side of the drive roller 52. The position of the side limiting plate 51 can be adjusted by the telescopic component 54. At the same time, the drive component 57 drives the driven roller 53 and the drive roller 52 to rotate. The driven roller 53 and the drive roller 52 reduce the friction between the side wall of the carton and the side wall of the side limiting plate 51. The pressure sensor 55 detects the pressure between the two side limiting plates 51 and the carton, and then determines whether the carton is centered between the two side limiting plates 51. The position of the side limiting plate 51 is adjusted by the telescopic component 54 until the pressure values ​​detected by the pressure sensor 55 on the two side limiting plates 51 are consistent.

[0034] In a preferred embodiment of the present invention, both extension rods 2 104 are located between the two extension rods 1 91, ensuring that the two extension rods 2 104 and the two extension rods 1 91 are located on the symmetrical sides of the carton, ensuring that when the extension rods 2 104 extend to the forward side of the carton, the extension rods 2 104 will not push one side of the carton and cause the carton to tilt, and also ensuring that the force exerted by the carton on the two extension rods 1 91 is consistent, and the force exerted by the carton on the two extension rods 2 104 is consistent.

[0035] In a preferred embodiment of the present invention, the laser detection assembly 7 includes a laser emitter and a laser receiver installed on the inner walls of both sides of the mounting frame 3. The laser emitter and the laser receiver are both located between extension rod 1 91 and extension rod 2 104. When the carton moves forward to the space between the laser emitter and the laser receiver, the laser receiver cannot receive the laser emitted by the laser emitter. At this time, the controller 2 controls the telescopic component 2 82 to push the lifting housing 83 upward, effectively ensuring that extension rod 2 104 can extend to the forward side of the carton and extension rod 1 91 can abut against the bottom of the carton.

[0036] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
