Technical Field
[0001] The utility model belongs to the technical field of tobacco processing equipment, in particular to an ink supply component of a rolling and splicing machine group. Background Art
[0002] The market share of medium and thin brand cigarettes is increasing, but cigarette machine equipment manufacturers have not designed their ink supply printing systems accordingly. The circumference of medium (φ6.37mm) and thin (φ5.4mm) cigarettes is 17.3% and 30% smaller than that of ordinary (φ7.7mm) cigarettes, respectively. The corresponding brand printing is also reduced to a certain extent, so the ink supply area and supply volume required per unit time should also be reduced compared to ordinary brands.
[0003] At present, when printing trademarks for medium and thin cigarettes, there is a problem of mismatch between the ink supply surface and quantity and demand. A small amount of ink will overflow when the equipment is running, followed by serious appearance quality defects such as blurred trademark printing patterns, uneven color depth, incomplete printing, and flying ink. Moreover, the ink supply volume cannot be changed by adjusting the motor speed of the ink supply gear pump.
[0004] Therefore, changing the structure of the ink supply assembly to meet the ink requirements for printing medium and thin cigarettes is the key to solving this series of quality defects. Utility Model Content
[0005] In view of this, the purpose of the utility model is to provide an ink supply component for a cigarette rolling unit, so as to solve the problem of ink supply adaptation and uniformity during the printing operation of medium and thin cigarettes.
[0006] The technical solution adopted by the utility model to solve its technical problems is:
[0007] A winding machine ink supply component comprises an ink nozzle opening, an ink distributing roller one, an ink distributing roller two, an ink transfer roller and a rigid printing roller, the circumferential surface of the ink distributing roller one is provided with an ink distributing roller one convex surface, the circumferential surface of the ink distributing roller two is provided with an ink distributing roller two convex surface, the circumferential surface of the ink transfer roller is provided with an ink transfer roller convex surface, the ink distributing roller one convex surface is in contact with the ink nozzle opening, the ink distributing roller two convex surface is in contact with the ink distributing roller one convex surface, and the ink transfer roller convex surface is in contact with the ink distributing roller two convex surface.
[0008] Furthermore, it also includes an ink roller, the circumferential surface of which is provided with an ink roller convex surface, and the ink roller convex surface is in contact with a convex surface of an ink distribution roller.

[0020] like Figure 1 As shown: This embodiment provides an ink supply component of a winding machine unit, including an ink nozzle port 1, an ink uniform roller 2, an ink uniform roller 6, an ink transfer roller 8, an ink roller 4 and a rigid printing roller 10, the circumferential surface of the ink uniform roller 1 is provided with an ink uniform roller convex surface 3, the width of the ink uniform roller 1 convex surface is smaller than the width of the ink uniform roller 1, the circumferential surface of the ink uniform roller 2 is provided with an ink uniform roller convex surface 7, the width of the ink uniform roller 2 convex surface is smaller than the width of the ink uniform roller 2, the circumferential surface of the ink transfer roller is provided with an ink transfer roller convex surface 9, the width of the ink transfer roller convex surface is smaller than the width of the ink transfer roller, the ink uniform roller convex surface is in contact with the ink nozzle port, the ink uniform roller convex surface is in contact with the ink uniform roller convex surface, and the ink transfer roller convex surface is in contact with the ink uniform roller convex surface.
[0021] The circumferential surface of the ink roller is provided with an ink roller boss surface 5, the width of the ink roller boss surface is smaller than the width of the ink roller, and the ink roller boss surface is in contact with both the first boss surface of the ink distribution roller and the second boss surface of the ink distribution roller.
[0022] The first convex surface of the ink-distributing roller, the second convex surface of the ink-distributing roller, the convex surface of the ink transfer roller, and the convex surface of the ink roller are all arranged in the center. A plurality of rigid printing roller prints 11 are evenly arranged around the circumference of the rigid printing roller.
[0023] The ink outlet width of the ink nozzle opening is reduced according to demand, which ensures clear and complete printing of the trademarks of medium and slim cigarettes, while also avoiding the situation where the ink accumulation, dripping and ink throwing caused by the excessive ink outlet width of the ink nozzle opening are avoided.
[0024] Here’s how it works:
[0025] The ink is pumped out from the ink nozzle opening 1 after the width is reduced, and the first convex surface of the ink distribution roller takes out the pumped ink; the convex surface of the ink roller contacts with the first convex surface of the ink distribution roller, so that the ink on the first convex surface of the ink distribution roller is evenly spread; the first convex surface of the ink distribution roller and the second convex surface of the ink distribution roller are connected, so that the ink is transferred to the second convex surface of the ink distribution roller; the convex surface of the ink roller contacts with the second convex surface of the ink distribution roller, so that the ink on the second convex surface of the ink distribution roller is evenly spread; the convex surface of the ink transfer roller contacts with the second convex surface of the ink distribution roller, receives the evenly spread ink, and transfers the ink to the printing surface of the steel printing roller, so that the steel printing roller can print a clear and complete trademark pattern on the cigarette paper.
[0026] In summary, when using the above-mentioned ink supply assembly, in the process of printing the trademarks of medium and thin cigarettes, there will be no problems such as blurred trademark printing patterns, uneven color depth, incomplete printing, and flying ink caused by the mismatch between the ink supply surface and quantity and the demand. The ink outlet width of the ink nozzle not only meets the requirements of clear and complete printing of the trademarks of medium and thin cigarettes, but also avoids the situation where the ink outlet width of the nozzle is too large, causing ink accumulation, dripping, and ink throwing; the ink is transferred through the narrowed convex surface, which reduces the ink supply surface and solves the problem of ink supply adaptation during the printing operation of medium and thin cigarettes; the uniformity of ink supply is improved by arranging the ink distribution roller; in addition, the convex surface design of the ink roller, the ink distribution roller, and the ink transfer roller ensures that the ink will not accumulate at the edge during the application process, while reducing the contact surface between the two contacting rollers, thereby reducing the phenomenon of ink drying caused by frictional heat.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
