Description

Drying mode and conveying mode of single-color or multi-color automatic printing machine
Technical Field
The invention relates to a printing machine, in particular to a drying mode of a single-color or multi-color automatic printing machine and a conveying mode thereof.
Background
At present, the method is as follows: the printing machine is mainly a rotary screen printing machine and a flat screen printing machine according to the division of printing plates. The printing plate of the rotary screen printing machine is cylindrical, the rotary screen printing machine directly adopts a conduction band, the printing speed is relatively high and can reach 5000m per hour, but the printing plate has the defect of being only capable of printing fixed patterns, and is suitable for batch production of grey cloth, and the application range is relatively narrow. The printing plate of the flat screen printing machine is a plane silk screen plate, and the cloth feeding of the flat screen printing machine is provided with a conduction band and a bedplate. Among them, the platen flat screen printing machine is called a circular or elliptical printing machine, and is suitable for various printing materials, mucilage, water slurry, printing ink and the like, and has wider application range.
The working tables of the traditional circular and elliptical printing machine run on the same plane according to circular or elliptical tracks, the occupied area is large, the number of tables is small, and the yield is greatly limited in the printing process. In addition, according to the printing process requirement, the printing surface is required to be dried after each color register is finished, and the next color register printing can be performed, and the existing drying mechanism adopts one-to-one open type heating due to the structural limitation of the printing machine, so that most of the whole heating energy is emitted in the working environment, a large amount of energy is wasted, and in order to improve the drying speed, the energy consumption is further improved only by increasing the power of the drying mechanism.
At present, a novel printing machine with small occupied area and large number of bedplate is provided with a three-dimensional feeding rack and a three-dimensional discharging rack, wherein two groups of vertical feeding or discharging mechanisms are arranged on the three-dimensional feeding rack and the three-dimensional discharging rack, and a horizontal direction adjusting mechanism connected with the two groups of vertical feeding or discharging mechanisms. Taking a vertical feeding mechanism as an example, feeding chains rotating in the vertical direction are arranged on two sides of the vertical feeding mechanism in the vertical direction, a plurality of feeding supporting pieces are arranged on the non-sprocket side of the feeding chains, and a printing platen supports between the feeding supporting pieces on two sides. The feeding chain is driven by the transmission mechanism to drive the printing platen to move in the vertical direction. When the printing machine works, the printing platen moves vertically from bottom to top under the action of the vertical feeding mechanism, and then is transferred to the other vertical feeding mechanism by the horizontal direction adjusting mechanism to move from top to bottom. Although the novel printing machine with the structure increases the number of the bedplate in the unit area and improves the yield, the novel printing machine still has certain problems: the two groups of vertical feeding mechanisms on the three-dimensional feeding and discharging rack adopt a chain structure, when the chain drives the printing bedplate, the two groups of vertical feeding mechanisms cannot be identical in pace, after errors are accumulated, the heights of the printing bedplate of the vertical feeding mechanisms at the two ends of the horizontal direction-adjusting mechanism are not in the same horizontal plane, so that the horizontal direction-adjusting mechanism cannot smoothly connect the printing bedplate, and therefore, the structure has larger problems in reliability and stability.
Therefore, with respect to the above-mentioned phenomenon, in patent CN102582225a, a platen moving pair of a full-automatic printing machine is mentioned, which includes a frame, and a feeding side lifting and conveying mechanism, a discharging side lifting and conveying mechanism and a horizontal conveying mechanism mounted on the frame, and the innovation points are that: the feeding side lifting conveying mechanism and the discharging side lifting conveying mechanism comprise lifting supporting brackets and lifting connecting brackets, platen supporting pieces are distributed on the lifting supporting brackets and the lifting connecting brackets, clamping driving mechanisms are arranged on the lifting supporting brackets and the lifting connecting brackets, and connecting driving mechanisms are arranged on the lifting connecting brackets. The structural form of the lifting conveying mechanism is convenient for improving the number of printing tables in the unit space on the basis of not increasing the occupied area of the printing machine, and ensures that the printing efficiency is improved. The lifting support bracket and the lifting handover bracket are used for clamping and loosening, and the lifting handover bracket is matched for realizing the sequential movement of the printing platen, so that the smooth handover of the printing platen is ensured, and the reliability and stability of equipment operation are improved.
Among the above-mentioned mechanisms, to the removal of platen, the cooperation of feeding side lift conveying mechanism, ejection of compact side lift conveying mechanism and horizontal conveying mechanism is adopted and realizes, and to the setting of feeding side lift conveying mechanism and ejection of compact side lift conveying mechanism among them, need use platen support piece, lift bearing support, press from both sides a plurality of parts such as tight actuating mechanism, lift handing-over support, handing-over actuating mechanism, wherein the spare part that involve is more, and whole structure is comparatively bulky, and installation maintenance etc. are all inconvenient, and also comparatively loaded down with trivial details when carrying out the lift operation.
