[0002] A carton printing machine is a printing device that can print the required text, patterns and other information onto the surface of a carton. It generally includes processes such as plate mounting, inking, printing, and paper feeding. During operation, the text and images to be printed are first made into a printing plate, which is then mounted on the printing machine. Then, the printing machine is operated by a person to evenly apply ink to the areas on the printing plate with text and images, and then directly or indirectly transfer it onto corrugated cardboard or a carton, thereby producing a printed copy that is identical to the printing plate.

[0003] Carton printing machines are specifically designed for printing on the surface of cartons. During printing, it is often necessary to print in the same position on the cartons, so the cartons need to be aligned. Manual alignment often requires stacking the cartons one by one, which is time-consuming and labor-intensive, and it is also troublesome to put the cartons onto the conveyor belt later.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0023] Reference Figures 1-6A pressing and aligning device for a carton printing machine includes a housing 1. Multiple support rods 10 and baffles 20 are fixedly installed on the bottom surface inside the housing 1. The multiple support rods 10 and baffles 20 are slidably fitted with lifting blocks 12. Multiple first top springs 11 are fixedly connected between the lower end face of the lifting block 12 and the bottom surface inside the housing 1. Each first top spring 11 is slidably fitted on the surface of the support rod 10.

[0024] A rectangular notch is provided on the lower inner wall of the outer casing 1. A third top spring is fixedly installed on the upper end of the notch. A pad 13 is fixedly installed on the upper end of the third top spring. The pad 13 is slidably connected to the side wall of the notch. Two adjacent sides of the pad 13 contact the first reset rod 14 and the second reset rod 15 respectively. The two first reset rods 14 are fixedly connected to the transition plate 22 through two Y-shaped rods. The second reset rod 15 is fixedly connected to the transition plate 22 through two crossbars. Slide rods 21 and multiple second top springs 16 are fixedly installed on the surfaces of the two transition plates 22 respectively. The other end of each second top spring 16 is fixedly installed on the inner wall of the outer casing 1. The other end of each slide rod 21 penetrates the inner wall of the outer casing 1 and a rectangular pull ring 17 is fixedly installed on the end exposed in the outer casing 1.

[0025] The top of the outer casing 1 has a through rectangular opening. A motor 2 is fixedly installed on one side of the outer casing 1. The drive shaft of the motor 2 passes through the outer casing 1 and extends into the interior of the outer casing 1. A first belt roller 3 is fixedly installed on the surface of the drive shaft. A friction belt 4 is rotatably sleeved on the surface of the first belt roller 3. A second belt roller 5 is rotatably sleeved inside the other end of the friction belt 4. Both ends of the shaft of the second belt roller 5 are rotatably installed on the inner wall of the outer casing 1. A main gear 7 is fixedly installed at the end face of the second belt roller 5. The main gear 7 is rotatably connected to the inner wall of the outer casing 1. The main gear 7 is meshed with a secondary gear 8. An auxiliary roller 9 is fixedly connected to one side of the secondary gear 8. Both ends of the secondary gear 8 and the auxiliary roller 9 are rotatably installed on the inner wall of the outer casing 1.

[0026] The auxiliary roller 9 has three right-angle slots arranged in a circular array. The right-angle slots are divided into long and short sides that are perpendicular to each other. Three soft springs 18 are fixedly installed on the long side of each right-angle slot. A rotating plate 19 is fixedly installed on the other end of each soft spring 18. One end of each rotating plate 19 is also fixedly installed on the long side of the right-angle slot. The height of the rotating plate 19 is longer than the short side of the right-angle slot and shorter than the long side of the right-angle slot. During the process of placing the carton board, the auxiliary roller 9 can use the rotating plate to press the previous carton board down a small distance, so that the next carton board is easier to place.

[0027] The friction belt 4 is made of wear-resistant rubber and has multiple wavy anti-slip textures on its surface. This is to increase the coefficient of friction between the cardboard and the friction belt 4, making subsequent operations easier.

[0028] The lifting block 12 is provided with three through straight slots, and the width of each straight slot is greater than the diameter of the first reset rod 14 and the second reset rod 15.

[0029] The height of the upper end face of the first reset rod 14, the second reset rod 15, and the baffle 20 is on the same horizontal plane as the height of the lower end face of the friction belt 4.

[0030] In this invention, when the lifting block 12 is in a natural no-load state, the vertical distance from the upper end of the lifting block 12 to the lower end of the friction belt 4 is equal to the thickness of a cardboard box. During use, the motor 2 is started (see attached diagram). Figure 3 At this time, the drive shaft of motor 2, friction belt 4, and main gear 7 all rotate clockwise, while the auxiliary gear 8 and auxiliary roller 9 rotate counterclockwise. Then, the cardboard is inserted through the horizontal opening at the top. Under the action of auxiliary roller 9 and friction belt 4, the cardboard enters the interior of outer casing 1. When the next cardboard is inserted, the rotating plate 19 on auxiliary roller 9 extends beyond the circular surface of auxiliary roller 9 under the action of soft spring 18. Simultaneously, one side of the rotating plate 19 abuts against the short side of auxiliary roller 9, while the other side abuts against the upper surface of the previous cardboard. Then... The cardboard board slides off the upper surface of the rotating plate, and then the next rotating plate 19 repeats the above operation, which facilitates the insertion of the next cardboard board. When the cardboard board is stacked to a certain height inside the outer shell 1, the lower end of the lifting block 12 abuts against the upper surface of the pad block 13, and the pad block 13 moves downward. The first reset rod 14 and the second reset rod 15 are no longer restricted in direction and begin to slide in the straight slot of the lifting block 12. Through the baffle 20, the orientation of the two first reset rods 14 and the second reset rod 15 is restricted, and the squeezing and alignment of the cardboard board is completed. When it is necessary to restore, the two pull rings 17 can be pulled outward.

[0031] To facilitate the operation of the carton printing machine, the drive shaft of motor 2 can be reversed. At this time, the friction belt 4 rotates counterclockwise and the auxiliary roller 9 rotates clockwise. Since the surface of the friction belt 4 is roughened, the friction coefficient between the friction belt 4 and the carton board surface is greater than the friction coefficient between the carton boards. The friction belt 4 and the auxiliary roller 9 can be used to gradually discharge the carton board from the inside of the outer casing 1 between the top of the auxiliary roller 9 and the bottom of the friction belt 4, and directly transport the carton board to the conveyor belt of the carton printing machine.

[0032] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
