Scanning type textile digital printing equipment

Abstract

The invention discloses scanning type textile digital printing equipment. The scanning type textile digital printing equipment comprises a cloth feeding mechanism, a printing conveying belt mechanism,a gantry sliding frame, a printing scanning vehicle, a belt glue distributing and removing device, a belt cleaning device, a printing control cabinet and an ink supply system; the printing conveyingbelt mechanism is arranged at the top of the rack, the gantry sliding frame stretches across the printing conveying belt mechanism, the printing scanning vehicle is arranged on the gantry sliding frame in a sliding mode, the belt glue distributing and removing device stretches across the front portion of the printing conveying belt mechanism, and the cloth feeding mechanism is arranged behind theprinting conveying belt mechanism, and the belt cleaning device is arranged below the printing conveying belt mechanism. The printing equipment has the advantages that the cloth feeding mechanism adapts to large and small rolls of cloth; automatic online real-time deviation correction and edge alignment of the cloth are achieved; the printing quality is high; the glue distributing function and theglue removing function are integrated; the belt cleaning device adopts the combination of a composite cleaning mode and composite drying, so that the cleaning effect is improved; water consumption islow, and energy conservation and environmental protection are achieved; and the ink supply system is fast to start and high in production efficiency.

Description

technical field [0001] The invention relates to a textile digital printing equipment, in particular to a scanning textile digital printing equipment. Background technique [0002] Scanning textile digital printing equipment is widely used in clothing, cutting pieces, clothing, leather, luggage, transfer paper, artificial flowers, shoe materials, flocking cloth, thick plate, cloth, etc. At present, scanning textile digital printing equipment includes a frame and a cloth loading mechanism set on the frame, a printing conveyor belt mechanism, a gantry carriage, a printing scanning car, a belt cleaning device, a printing control cabinet, and an ink supply system; among them, the supply The ink system includes primary ink tank, ink supply pump, pre-stage filter, secondary ink inlet cartridge, nozzle, circulation pump, secondary outlet ink cartridge, degassing lung, post-stage filter; primary ink barrel, ink supply pump, The pre-filter, degassing lung, post-filter, secondary inle...

AI Technical Summary

Problems solved by technology

[0005] However, the existing scanning textile digital printing equipment has the following technical problems (1) need to be equipped with a separate cloth rack; (2), the edge-aligning device is only for edge-aligning during the cloth-running process, requiring a large space for 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; However, if the sticking is not tight, the nozzle will be damaged and the fabric will be scrapped; (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 fabric used. , needs frequent adaptation and adjustment; 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) manual glue The flatness is poor, and the work efficiency of cloth glue removal is low; (7) the combination of cleaning methods is relatively simple, and the cleaning effect on the cloth fluff stuck on the surface of the conveyor belt is not ideal; (8) the water consumption is large, the waste water discharge is large, and there is no waste water recovery Using the system is not conducive to energy saving and environmental protection; (10) The temperature parameters of the ink are unstable and easily affected by the environment, resulting in poor printing effect consistency under different temperature conditions; The ink cartridge occupies the space of the equipment, which makes the maintenance and operation of the equipment unsatisfactory; the height of the secondary outlet ink cartridge is the same as the height of the secondary inlet ink cartridge due to structural reasons, and there is no height difference to form a natural flow rate; the circulation flow rate required by the nozzle can only be passed through the circulation The pump generates, and the nozzle discharges the air bubbles inside. It takes a long time for the nozzle to reach the ideal nozzle working state, generally at least 4 to 5 hours
