Description

Technical Field

[0001] The utility model relates to the technical field of packaging box printing, in particular to a printing device for packaging box production which is easy to repair. Background Art

[0002] A printing press for producing food packaging boxes, with the announcement number CN109177465B, is easy to maintain and relates to the technical field of printing presses. This allows for maintenance without shutting down the machine when a partial fault occurs. The printing press for producing food packaging boxes, which is easy to maintain, includes a printing device and a traction device. The traction device is located below the printing device. The printing device includes a machine housing. A first motor is fixedly mounted on the inner wall of the bottom of the machine housing, and one end of the first motor is movably connected to a first rotating shaft via a chain. When a fault occurs on the printing roller of the printing press, the second motor is turned off to stop the printing device. The handle is then moved in the rotating groove. The other end of the handle drives the threaded disc to rotate. The engagement of the threaded disc with the threaded layer causes the clamping block to move on the sliding track to the periphery of the third rotating shaft and clamp it.

[0003] The above-mentioned printing machine for producing food packaging boxes that is easy to maintain cannot flatten the packaging box cardboard during printing. When the surface of the packaging box is convex, printing may fail. During maintenance, the space required for maintenance cannot be adjusted, which may cause maintenance and inspection personnel to perform maintenance in a small space, causing inconvenience to maintenance and reducing work efficiency.

[0022] See also Figure 1-3 The utility model provides a technical solution: a printing device for packaging box production that is easy to repair, including a printing shell 1 and an auxiliary mechanism. A printing plate 3 is provided inside the printing shell 1, and a movable shell 6 is provided below the printing plate 3; the auxiliary mechanism includes a movable mechanism 5 and a flattening mechanism 7. The movable mechanism 5 is provided on the printing shell 1, and the movable mechanism 5 includes a motor 501, a threaded rod 502 and a limit rod 503. The motor 501 is fixedly installed on the inner bottom of the printing shell 1, and the output shaft of the motor 501 is fixed. A threaded rod 502 is installed, and the outer wall of the threaded rod 502 is threadedly connected to the movable shell 6. Two groups of limit rods 503 are fixedly installed on the inner bottom of the printing shell 1. One end of the limit rod 503 extends to the interior of the movable shell 6. The limit rod 503 and the movable shell 6 are slidably installed. When the pressure roller 704 fails and needs to be repaired, the movable mechanism 5 is used to drive the movable shell 6 to move, so that one group of pressure rollers 704 can move and increase the distance between them. The increase in the distance between the two groups of pressure rollers 704 makes it easier for operators to perform inspection and maintenance.

[0023] The flattening mechanism 7 is arranged on the printing shell 1, and the flattening mechanism 7 includes a second motor 701, a rotating rod 702, a gear 703 and a pressure roller 704. The second motor 701 is fixedly installed on the other side of the printing shell 1, and two groups of rotating rods 702 are rotatably installed inside the printing shell 1. The output shaft of the second motor 701 extends to the interior of the printing shell 1 and is fixedly installed with a group of rotating rods 702. A group of gears 703 are fixedly installed on the outer wall of the rotating rod 702, and the two groups of gears 703 are meshed with each other. A group of pressure rollers 704 are fixedly installed on the outer wall of the rotating rod 702. The flattening mechanism 7 is used to drive the packaging box cardboard to move into the interior of the printing shell 1, so that the surface of the packaging box cardboard entering the interior of the printing shell 1 is smooth, reducing the situation of printing failure caused by uneven surface of the packaging box, and directly improving work efficiency.

[0024] A hydraulic rod 2 is fixedly installed on the top of the printing shell 1, and the free end of the hydraulic rod 2 extends to the interior of the printing shell 1 and is fixedly installed on the printing plate 3. One end of a set of rotating rods 702 extends to one side of the printing shell 1 and is fixedly installed with a set of pulleys 8. Two sets of rotating rods 10 are rotatably installed inside the printing shell 1, and one end of a set of rotating rods 10 extends to one side of the printing shell 1 and is fixedly installed with another set of pulleys 8. A belt 9 is provided between the two sets of pulleys 8 and is connected through the belt 9.

[0025] A group of rollers 11 are fixedly mounted on the outer wall of the rotating roller 10 , and a conveyor belt 12 is sleeved between the rollers 11 and the rollers are connected through the conveyor belt 12 .

[0026] A guide platform 4 is fixedly mounted on the inner bottom of the printing housing 1 .

[0027] Rectangular openings are provided on the front and rear sides of the printing housing 1 , and four sets of supports 13 are fixedly mounted on the bottom of the printing housing 1 .

[0028] Working principle: When work is required, the packaging box cardboard to be printed is placed between the two sets of pressing rollers 704 through the rectangular opening opened on the front side of the printing shell 1. By controlling the start of the second motor 701, the output shaft of the second motor 701 rotates to drive the two sets of meshing gears 703 to rotate, and the two sets of gears 703 rotate to drive the two sets of pressing rollers 704 to rotate. The two sets of pressing rollers 704 rotate to flatten the cardboard and convey it into the interior of the printing shell 1, so that the cardboard falls on the conveyor belt 12. A set of rotating rods 702 rotates to drive a set of pulleys 8 to rotate, and the action of the belt 9 drives another set of pulleys 8 to rotate. The rotation of the other set of pulleys 8 drives a set of rotating rods 10 to rotate. The rotation of a set of rotating rods 10 drives a set of rollers 11 to rotate, and the action of the conveyor belt 12 drives another set of rollers 11 to rotate, so that The cardboard can move on the conveyor belt 12. When the cardboard moves to the bottom of the printing plate 3, the hydraulic rod 2 is started. The free end of the hydraulic rod 2 drives the printing plate 3 to move downward. The downward movement of the printing plate 3 can print the cardboard. The printed packaging box cardboard moves and falls onto the guide table 4. It slides out of the interior of the printing shell 1 through the opening on the rear side of the guide table 4 and the printing shell 1 for collection. When the pressure roller 704 fails and needs to be repaired, the motor 501 is started by control. The output shaft of the motor 501 rotates to drive the threaded rod 502 to rotate. Through the action of the limit rod 503, the threaded rod 502 rotates to drive the movable shell 6 to move downward. The downward movement of the movable shell 6 drives a group of pressure rollers 704 to move downward, so that the two groups of pressure rollers 704 are separated, which is convenient for maintenance and inspection.
