Description

Technical Field

[0001] This invention relates to the field of corrugated cardboard printing tooling technology, specifically to a highly efficient and environmentally friendly corrugated carton printing device. Background Technology

[0002] Corrugated cardboard has the advantages of being inexpensive and having adequate structural strength, and is commonly used as a board material for making packaging boxes. In conventional corrugated box production, patterns need to be printed on the corrugated cardboard to ensure the aesthetics of the packaging. However, in existing technologies, to ensure the accuracy of the pattern placement on the finished corrugated cardboard, sufficient allowance is left on the substrate during printing, and then the excess area is cut off after printing. This results in a lot of waste material from the corrugated cardboard raw materials. This method of corrugated cardboard printing requires handling excess waste, reduces printing efficiency, and does not conform to the concept of environmentally friendly production. Therefore, it is necessary to design a device for corrugated cardboard printing that enables efficient and environmentally friendly printing production. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a highly efficient and environmentally friendly corrugated cardboard printing device. This device utilizes a fixture capable of precisely positioning the substrate, and the positioning and printing fixtures are configured as a rotatable, movable structure. This facilitates precise positioning and printing of patterns during corrugated cardboard printing, thereby reducing subsequent cutting and waste disposal processes, thus improving printing production efficiency and reducing waste emissions.

[0004] To achieve the above objectives, the present invention adopts the following technical solutions:

[0005] It includes a base, a frame, a worktable, and an printing unit. The frame is fixedly mounted on the base, the worktable is mounted inside the frame, and the printing unit is mounted above the worktable. It also includes:

[0006] A sheet metal positioning mechanism is mounted on the machine frame and positioned above the worktable.

[0007] A printing mounting frame is screwed onto the upper left side plate of the frame via a rotating shaft, and the printing press unit is fixedly mounted on the printing mounting frame.

[0010] In use, the unloading mechanism is moved to the front of the worktable, the board positioning mechanism is placed on the worktable, and the corrugated paperboard to be printed is fed into the board positioning mechanism for positioning, so that the board is placed on the worktable. Then, the printing mounting frame is rotated above the worktable by the printing rotary cylinder. Then, the printing unit passes through the board positioning mechanism to print on the board on the worktable. After printing is completed, the printing mounting frame is rotated and lifted vertically to lift the board positioning mechanism. Then, the finished board on the worktable is pushed backward and pushed out of the worktable by the unloading mechanism.

[0011] Preferably, a platform is fixedly mounted on the base, a lifting cylinder is fixedly mounted on the platform, and the worktable is fixedly mounted on the lifting shaft of the lifting cylinder.

[0031] The unloading rotary cylinder is fixedly mounted on the frame, and the output shaft of the unloading rotary cylinder is driven by the drive shaft.

[0032] In use, the tension spring pulls the guide sleeve, which in turn drives the unloading push plate to press against the worktable. The unloading rotary cylinder drives the drive shaft to rotate, which in turn drives the connecting rod to rotate.

[0081] When using this device, the printing mounting frame 6 is rotated and lifted to a vertical position by the printing rotary cylinder 7, thereby lifting the printing press unit 4 away from the positioning mounting frame 5-1. The drive motor 9-5 drives the lead screw pair 9-1 to rotate. The lead screw pairs 9-1 are driven by bevel gears to achieve synchronous rotation of all lead screw pairs 9-1. The lead screw pair 9-1 drives the driving rack 9-2 to slide. The guide frame 9-4 guides the driven rack 9-3. The driving rack 9-2 drives the driven rack 9-3 to move in a direction perpendicular to the driving rack 9-2.

[0082] The corrugated paper substrate to be printed is placed in the positioning mounting frame 5-1, and the positioning plate is placed inside the pusher plate 5-3. Then, the pusher plate 5-3 is moved in the opposite direction to reset, and the pusher plate 5-3 pushes the substrate to position, feeding the substrate from the feeding port of the positioning mounting frame 5-1 onto the worktable 3. Then, the printing mounting frame 6 is laid flat, and the printing mounting frame 6 holds the printing unit 4 above the positioning mounting frame 5-1. The printing unit 4 is started and passes through the feeding port to print on the substrate.

[0083] After printing is completed, the printing mounting frame 6 is lifted vertically. Then, the positioning mounting frame 5-1 is rotated and lifted vertically by the positioning rotary cylinder 5-2. Next, the unloading rotary cylinder 8-5 drives the drive shaft 8-1 to rotate. The drive shaft 8-1 drives the connecting rod 8-2 to rotate. The tension spring 8-4 pulls the guide sleeve 8-3, and then the guide sleeve 8-3 pulls the unloading push plate 10 against the upper surface of the worktable 3. The connecting rod 8-2 drives the guide sleeve 8-3 to move. The guide sleeve 8-3 drives the unloading push plate 10 to move from front to back on the upper surface of the worktable 3, pushing the printed corrugated cardboard off the worktable 3 to complete the unloading.

[0084] The technical advantages achieved by adopting the above technical solution are as follows:

[0085] 1. This device uses a rotatable and liftable printing mounting frame 6 to install the printing press unit 4, and a positioning mounting frame 5-1 with a pusher plate 5-3 is covered and mounted on the worktable 3, so as to achieve precise placement of the substrate before printing, thereby ensuring the accurate positioning of the printed pattern and reducing the cutting work and waste disposal work after the printing of the substrate.

[0086] 2. This device uses a lifting cylinder 12 to install the worktable 3, and sets a discharge push plate 10 on the worktable 3.
