Description

Technical Field

[0001] The invention relates to a material conveying device for a plastic cup printing machine, in particular to an online material storage device. Background Art

[0002] At present, plastic cups are first made by cup making machines, then transported to the loading unit of the printing press by manual handling, and transported to the inside of the printing press through a stepped loading rack. After printing, they are transported to the packaging machine equipment by manual transportation, and the packaging machine equipment packs them according to a fixed quantity.

[0003] Curved surface printing machine, also known as curved surface offset printing machine, cup and bowl printing machine, pad printing machine, cylindrical curved surface printing machine, bottle cap curved surface printing machine, for daily use of plastic or metal paper made of cups, bowls, hoses and bottle caps made of outer surface usually need to print patterns for beauty, the entire printing process of the automatic printing production line includes: loading, testing, corona, printing, curing, defective product detection, finished product delivery.

[0004] Cup making machine, also known as cup making machine, is one of many thermoforming machines. Because its forming principle uses positive pressure, it can be called "positive air pressure thermoforming machine". It uses pelletized sheets as raw materials to produce plastic cups.

[0005] At present, the fast-moving consumer beverage packaging industry is dominated by plastic cups. With the gradual development of the market and the changes in demand, the requirements for production efficiency are getting higher and higher. In the process of changes in external demand, the shortcomings and defects of cup printing equipment in the current market are revealed. The specific defects are as follows:

[0006] Existing manufacturers simply connect the two machines in series through a simple conveyor belt, which only solves the problem of manual handling, but does not solve the problem of how to deal with the difference in processing time between the two machines. Most cup making machines on the market produce 800-1200 cups per minute, while the printing machine is limited by the printing process and the printing speed is 200-400. The speed of the printing machine is much lower than that of the cup making machine, which will cause the accumulation of cups, causing the main machine of the cup making machine to stop frequently and reduce production efficiency. Summary of the invention

[0007] The invention provides an online material storage device, which solves the problem of the main machine stopping at a later stage due to the difference between the output of a cup making machine and the printing speed of a printing machine.

[0008] In order to solve the above technical problems, the technical solution adopted by the present invention is:

The toggle rod is connected to the bottom of the toggle longitudinal rods of the two toggle rod connecting frames. The two toggle rods are parallel to the rotating shaft. The output end of the driving cylinder is connected to the end of the rotating shaft through a driving connecting rod.

[0012] Furthermore, the stepped loading rack assembly also includes a plurality of parallel loading hoppers and two chains, the two chains are respectively connected to the loading hoppers, the top of the chain is located above the second frame, and the bottom of the chain is located below the second frame.

[0018] The beneficial effects of the present invention are:

[0019] The cups produced by the cup making machine are transported to the cup pushing assembly, which is equipped with a counting sensor. When a fixed value is reached, the counting sensor sends a signal, and the cylinder at the bottom of the push rod assembly receives the signal and moves to push a fixed number of cups to the bottom of the lever assembly. The cylinder of the lever assembly starts to move and pushes the cups to direction A or B. After being moved to direction A, the cups will fall on the conveyor belt assembly and then be transported to the printing press for printing; after being moved to direction B, the cups will fall on the hopper of the stepped loading rack and reverse through the hopper. At this time, the paddle on the loading plate assembly will be opened by the cylinder to ensure that the cups pushed to direction B will not be blocked. The cups are smoothly transported to the bottom and then dropped for storage, thereby solving the problem that the cup making speed of the cup making machine is higher than the printing speed of the printing press.

[0020] When the cup making machine fails and stops running and needs manual loading, the printing machine can still load the printed cups manually through the loading plate assembly. At this time, the paddle of the loading plate assembly is closed, so that the cups can move upward with the loading hopper normally, and the cups are transferred to the paddle assembly and the conveyor belt assembly to ensure the normal operation of the printing machine.
