Abstract
The utility model discloses a single servo shaftless flexographic printing unit which comprises a rack, wherein an impression cylinder, an anilox roller, a guide roller and an ink supply mechanism are arranged on the rack; and the impression cylinder and the anilox roller are in transmission connection with a power driving mechanism. By adopting the above scheme, the printing unit reduces the usage of gears, and reduces accumulated jumping errors, so as to be more accurate in transmission, thus realizing the printing of fine prints. A control system with shaftless transmission well realizes synchronous control of tension constancy and speed in the printing unit, and also can realize tension control in rolling and unrolling processes. In the printing production process, the tension control is stable, the fluctuation range is small, a system is convenient to operate and reliable to run, and requirements of printing technology on the tension control in the printing process are met.
Description
Technical field
The utility model relates to a kind of printing unit, relates to the servo shaftless flexo printing of a kind of list unit specifically, belongs to the printing equipment technical field.
Background technology
The flexo in past is printed the used transmission of unit for through-drive is arranged, and each printing element all is to come transferring power through same axle, does not use servomotor directly to drive.
In the transmission of traditional printing unit, pass through: the transmittance process of variable-frequency motor-band transmission-major axis-gear-box-gear-impression cylinder (bottom roller), the efficient of transmission is not high, and mechanism is complicated, processing trouble, assembling difficulty.
Along with the development of package packing machine, mechanical and electric being used more and more paid close attention to, and reduced mechanical use on the one hand, reduced accumulated error, also improved the efficient of transmission on the other hand, promoted printing quality.
The utility model content
The problem that the utility model will solve provides a kind of raising transmission efficiency, promotes the servo shaftless flexo printing of the list unit of printing quality.
In order to address the above problem, the utility model adopts following technical scheme:
The servo shaftless flexo printing of a kind of list unit comprises frame, and impression cylinder, anilox roll, deflector roll and ink-supplying mechanism are installed on the said frame, and said impression cylinder and anilox roll and Power Drive Unit are in transmission connection.
Below be the further improvement of the utility model to such scheme:
Said Power Drive Unit comprises through rack-mounted reductor of support and servomotor; The end that the end of said impression cylinder is equipped with impression cylinder gear, anilox roll is equipped with the screen roller gear; On the power output shaft of said reductor output gear is installed, said output gear and impression cylinder gear and screen roller gear are in transmission connection respectively.
Further improve:
Plate cylinder input gear also is installed on the said impression cylinder.
The utility model adopts such scheme, has reduced the use of gear, and the runout error of accumulation reduces, and makes transmission more accurate, thereby can realize the printing of exquisite printing.Do not have driven off by shaft control system and realized that well the constant tension in the printing unit controls with speed synchronization, and rolling and unreel the Tension Control in the process.In the print production process, Tension Control is stable, fluctuation range is little, and system features in convenient, reliable has satisfied the needs of typography to Tension Control in the printing.
Compare with traditional major axis transmission, no through-drive is simplified more, more easily control and operation; In adopting no driven off by shaft printing unit, only pass through: the transmission of servomotor-gear-impression cylinder, transmission efficiency increases greatly; Production cycle obviously shortens, thereby we adopt the kind of drive of servomotor; This mode is not only simple in structure, and is easy to assembly, and the chromatography of when printing is regulated quick.
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Among the figure: the 1-impression cylinder; The 2-anilox roll; The 3-ink-supplying mechanism; The 4-output gear; The 5-deflector roll; The 6-frame; The 7-servomotor; The 8-support; The 9-reductor; 10-impression cylinder gear; 11-screen roller gear; 12-plate cylinder input gear.
The specific embodiment
Embodiment; Like Fig. 1, shown in Figure 2, the servo shaftless flexo printing of a kind of list unit comprises frame 6; Impression cylinder 1, anilox roll 2, deflector roll 5 and ink-supplying mechanism 3 are installed on the said frame 6, and said impression cylinder 1 is in transmission connection with anilox roll 2 and Power Drive Unit.
Like Fig. 3, shown in Figure 4; Said Power Drive Unit comprises through support 3 and is installed in reductor 2 and servomotor 1 on the frame 6; The end that the end of said impression cylinder 1 is equipped with impression cylinder gear 10, anilox roll 2 is equipped with screen roller gear 6; Output gear 4 is installed on the power output shaft of said reductor 2, and said output gear 4 is in transmission connection respectively with impression cylinder gear 10 and screen roller gear 6.
As shown in Figure 5, plate cylinder input gear 8 also is installed on the said impression cylinder 1.
Compare with traditional major axis transmission, no through-drive is simplified more, more easily control and operation; In adopting no driven off by shaft printing unit, only pass through: the transmission of servomotor-gear-impression cylinder, transmission efficiency increases greatly; Production cycle obviously shortens, thereby we adopt the kind of drive of servomotor; This mode is not only simple in structure, and is easy to assembly, and the chromatography of when printing is regulated quick.
