Description

Technical Field

[0001] This utility model relates to the field of plastic cup processing technology, and in particular to an ink feeding device for a plastic cup printing machine. Background Technology

[0002] Plastic cups are commonly used disposable containers for drinking fruit juices, soft drinks, sweet wines, and sour cocktails. There are generally two methods for manufacturing disposable plastic cups: injection molding and thermoforming. However, injection molding is costly and inefficient. Therefore, plastic cups are often produced using the more efficient thermoforming method. Thermoforming is a specialized plastic processing method that shapes thermoplastic sheets into various products. The plastic sheet is clamped in a frame and heated to a softened state. Under external force, it is forced to conform to the mold surface to achieve a shape similar to the mold surface. After cooling and setting, it is trimmed to obtain the finished product.

[0003] Existing plastic cups require printing after manufacturing. Compared to traditional printing, ink printing makes the printed patterns and text on plastic cups more aesthetically pleasing, and ink printing equipment is increasingly used in daily life and the market. However, the ink feeding device in plastic cup printing machines is prone to uneven ink feeding during the process, leading to problems such as unclear printing lines and inconsistent ink application. Utility Model Content

[0004] Therefore, in view of the above problems, this utility model proposes an ink feeding device for a plastic cup printing machine that is easy to adjust and has good printing effect.

[0005] To solve this technical problem, this utility model adopts the following solution: an ink feeding device for a plastic cup printing machine, comprising a printing machine body and an ink feeding mechanism disposed on the printing machine body. The ink feeding mechanism includes a frame, on which an ink box, an ink fountain roller, an ink transfer roller, an ink conveying roller, and an ink leveling roller are sequentially installed from the outside to the inside. The ink fountain roller, ink transfer roller, ink conveying roller, and ink leveling roller are tangent to each other in sequence. The ink box is fixed to the frame by a fixing device. A semi-circular groove is provided at one end of the ink box near the inner side of the frame. The ink fountain roller is inserted into the semi-circular groove of the ink box and rotatably connected to the ink box. The ink fountain roller is rotatably connected to the frame. The ink cartridge is also equipped with a feeding adjustment plate and an adjustment mechanism. The feeding adjustment plate is inclined inside the ink cartridge and tilts downwards from the side away from the semicircular groove. The adjustment mechanism includes an adjustable handle, an adjustment seat, and a fixing rod. The adjustment seat is movably located at the bottom of the ink cartridge, at the bottom of the ink trough. One end of the fixing rod passes through the ink trough of the ink cartridge and is fixedly connected to the feeding adjustment plate. The other end of the fixing rod is adjustablely inserted through the adjustment seat. The adjustable handle passes through the bottom of the ink cartridge to position the adjustment seat.

[0006] In a further improvement, the bottom of the ink cartridge is provided with a base plate, and the adjustment seat is located between the bottom of the ink trough of the ink cartridge and the base plate. The adjustable handle passes through the base plate to position the adjustment seat.

[0007] In a further improvement, the adjusting seat is provided with a threaded hole, and the fixing rod at one end of the adjusting seat is provided with an external thread that matches the threaded hole of the adjusting seat. The fixing rod, through the external thread and the threaded hole of the adjusting seat, adjusts the position of the fixing rod in the ink box ink trough, thereby adjusting the distance between the feeding adjusting plate and the ink fountain roller inserted into the semi-circular groove of the ink box, and adjusting the ink supply amount.

[0008] In a further improvement, the ink cartridge is also provided with a second adjustment mechanism. The second adjustment mechanism includes multiple adjustment rods arranged side by side at intervals. One end of each adjustment rod is inserted into the ink groove of the ink cartridge and extends to abut against the bottom surface of the feeding adjustment plate near the edge of the semi-circular groove of the ink cartridge. The other end of each adjustment rod is located on the side of the ink cartridge away from the semi-circular groove. The end of each adjustment rod that abuts against the feeding adjustment plate is a telescopic end, and the free end of each adjustment rod outside the ink cartridge is the adjustment end. The adjustment end of each adjustment rod adjusts the telescopic end to adjust the distance between the feeding adjustment plate and the ink fountain roller inserted into the semi-circular groove of the ink cartridge, thereby adjusting the ink supply.

[0009] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows: By setting a feeding adjustment plate and an adjustment mechanism on the ink box of the ink feeding mechanism, and tilting the feeding adjustment plate inside the ink box with the plate tilting downwards from the side away from the semicircular groove, the position of the feeding adjustment plate can be adjusted by the adjustment mechanism. This allows for adjustment of the distance between the feeding adjustment plate and the ink fountain roller inserted into the semicircular groove of the ink box, making the ink amount on the ink fountain roller controllable. This achieves adjustment of the ink amount, making it convenient to use and ensuring uniform ink application for good printing results. By setting a second adjustment mechanism to fine-tune the feeding adjustment plate, one or more adjustment rods can be individually adjusted to adjust the distance between the feeding adjustment plate and the ink fountain roller at specific points during printing, thus more precisely adjusting the ink amount on the ink fountain roller. This makes it more convenient to use, ensures more uniform ink application, and allows for easy and convenient adjustment at any time, making it suitable for widespread application.
