Description

Technical Field

[0001] This utility model relates to the field of pulp molding technology, and in particular to an online pad printing mechanism for pulp egg cartons. Background Technology

[0002] Pulp molding, also known as stereolithography, uses pulp as raw material and molds it into a specific shape using special molds on a molding machine. Pulp molding offers advantages such as renewable raw materials, convenient transportation, and environmental friendliness. It is mainly used for food containers, tableware, and product trays. For example, egg cartons, used for packaging eggs, require labels and printed information during the production process.

[0003] A search revealed that Chinese utility model patent CN202323494351.6 discloses a high-speed plateless printing machine for molded pulp egg cartons. The machine includes a frame, a drive motor reducer mounted on the surface of the frame, a drive gear mounted on the outer side of the output shaft of the drive motor reducer, and a sprocket drive shaft mounted on the surface of the frame and behind the drive motor reducer, with a driven gear mounted on the outer side of the sprocket drive shaft. This utility model, through the arrangement of the drive motor reducer, spiral feeding mechanism, conveyor chain, and stacking machine, uses a single drive motor reducer as the power source to achieve synchronous operation of the drive conveyor chain, spiral feeding mechanism, and stacking machine. This results in a compact structure and small footprint for the high-speed plateless printing machine, enabling rapid input and printing without cumbersome plate-making operations. It also boasts a high degree of automation, reducing manual intervention and improving production efficiency.

[0004] While the existing high-speed plateless printing press for molded pulp egg boxes can meet basic usage requirements, it has the following drawbacks: low efficiency; poor positioning due to the use of a conveyor line + position detection structure, resulting in large printing position deviations; and it does not achieve fully automated pad printing. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an online pad printing mechanism for pulp egg cartons, which addresses the above-mentioned deficiencies of the prior art. The mechanism uses a stop-and-go control system, advancing one notch at a time and then stopping to allow the pad printing machine to print the pattern online. After printing is completed, it advances one notch again for the next printing. Repeating the above actions allows for continuous and uninterrupted online printing of patterns on egg cartons, greatly reducing printing position deviation and achieving fully automated pad printing with high efficiency.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] An online pad printing mechanism for pulp egg cartons includes a frame on which a pad printing machine is mounted. The frame also includes a servo motor, a speed reducer, and a push block structure. The push block structure is located below the pad printing machine. The speed reducer is connected to both the servo motor and the push block structure. The push block structure includes a push block guide rail, a conveyor bar, and several push blocks. The push blocks are slidably mounted on the push block guide rail, and the conveyor bar is connected to both the speed reducer and the push blocks.

[0008] Preferably, the push block includes a first push block and a second push block, which are arranged symmetrically from left to right.

[0009] Preferably, a push block space is formed between the first push block and the second push block.

[0010] Preferably, a transmission sprocket is provided between the reducer and the transmission bar, the transmission sprocket is connected to the reducer via a drive shaft, and the transmission bar is sleeved on the outside of the transmission sprocket.

[0011] Preferably, the frame includes a support rod, a connecting rod, and a side plate, wherein the connecting rod is connected to the support rod, and the side plate is installed on the upper side of the support rod.

[0012] Preferably, the bottom of the support rod is provided with a plurality of telescopic support feet.

[0013] The online pad printing mechanism for pulp egg cartons provided by this utility model, using the above technical solution, has the following beneficial effects: The frame of the online pad printing mechanism for pulp egg cartons is equipped with a servo motor, a reducer, and a push block structure. The push block structure is located below the pad printing machine. The reducer is connected to both the servo motor and the push block structure. The push block in the push block structure is slidably mounted on the push block guide rail. The conveyor bar is connected to both the reducer and the push block structure. By setting the servo motor, reducer, and push block structure, the movement and stop positions are precisely controlled, ensuring minimal deviation in printing position accuracy. Fully automated pad printing is achieved using movement and stop control. The machine advances one notch and then stops, allowing the pad printing machine to print the pattern online. After printing is complete, it advances one notch again for the next printing. Repeating this action allows for continuous and uninterrupted online printing of patterns on egg cartons, resulting in high production efficiency and meeting capacity requirements.
