Rack system of digital printing machine

Abstract

The invention discloses a rack system of a digital printing machine. The system comprises a rack, a printing conveying belt mechanism is arranged at the top of the rack, a gantry sliding frame stretches across the upper portion of the printing conveying belt mechanism, a cloth feeding mechanism is arranged behind the printing conveying belt mechanism, and a belt cleaning device is arranged below the printing conveying belt mechanism; the cloth feeding mechanism comprises an inflatable shaft, a large roll wrap angle roller, a cloth passing roller a, a constant-tension floating roller, a cloth passing roller b, a cloth passing roller c, a moving roller and an expanding wrap angle roller which are all arranged on the rack; a lifting guide mechanism for driving the constant-tension floating roller to act is arranged; and an unwinding deviation correcting system for correcting the position of cloth is arranged. The system has the advantages that the cloth feeding mechanism simultaneously adapts to large and small rolls of cloth, so that the cost is saved; automatic online real-time deviation rectification and edge alignment of the cloth are realized; the printing quality is high; the belt cleaning device combines a composite cleaning mode and a composite drying mode, so that the cleaning effect is improved; the system is small in water consumption, energy-saving and environmentallyfriendly; and the production efficiency is improved.

Description

technical field [0001] The invention relates to a scanning digital printing machine, in particular to a frame structure of the scanning digital printing machine. Background technique [0002] Scanning digital printing machines are widely used in clothing, cutting pieces, clothing, leather, luggage, transfer paper, artificial flowers, shoe materials, flocking cloth, thick plate, cloth, etc. At present, the frame system of a digital printing machine includes a frame and a cloth loading mechanism arranged on the frame, a printing conveying belt mechanism, a gantry carriage, and a belt cleaning device; The large roll wrapping roller, the cloth passing roller, the constant tension roller, the pressure roller and the widening corner wrapping roller on the frame; the frame is equipped with a device for aligning the fabric; the constant tension roller is equipped to maintain the tension The constant tension mechanism adopts counterweights or cylinders are installed at both ends of ...

AI Technical Summary

Problems solved by technology

[0003] However, the rack system of the existing digital printing machine has the following technical problems: (1) it needs to be equipped with a separate cloth frame; (2), the edge-to-edge device is only aligned during the cloth-running process, requiring a large space to Buffering; (3) The position of the moving roller is fixed, and there is no chance to eliminate the creases of the cloth during printing; (4) The moving roller does not have a heating device, so that the cloth can be more closely attached to the printing conveyor belt; (5) It is inconvenient to adjust the counterweight of the constant tension mechanism, because there are too many types of fabrics, and the adaptability of the counterweight is not necessarily suitable for the used one. The fabric needs to be frequently adapted and adjusted; and the cylinder installed at both ends of the constant tension roller, due to the inevitable reality difference in the quality of the cylinder, it is difficult to control the balance of the force on both sides, and it is prone to jamming; (6) Cleaning means The combination is relatively simple, and the cleaning effect on the cloth lint sticking to the surface of the conveyor belt is not ideal; (7) the water consumption is large, the waste water discharge is large, and there is no waste water recycling system, which is not conducive to energy saving and environmental protection
