Multifunctional large-area flatbed printing machine

Abstract

The invention relates to a multifunctional large-area flatbed printing machine which consists of a front plate, a base, a guide rail, a screw, a rack fixing plate, a printing machine flat plate, a key plate, a printing machine head, a clutch, a belt, a synchronizing wheel A, a motor, a synchronizing wheel B, a transmission shaft, a synchronizing wheel C, a lateral plate, a bearing, a lifting motor, a chain, a chain wheel, a printing machine head driving belt, a small transmission shaft and a synchronizing wheel D. Guide rail transmission is adopted to replace screw transmission in the prior art; a transmission manner of combining a steel rope and the belt is adopted; the clutch is adopted to control the printing machine head to reciprocate; and a lifting mechanism is adopted to regulate the distance between the printing machine head and a printed material.

Description

technical field [0001] The invention relates to a printer, in particular to a multi-functional large-area flat-panel printer guided by a guide rail, driven by a combination of a steel rope and a belt, and capable of synchronously printing and driving. Background technique [0002] At present, there are many printers on the market, including large flatbed printers, small flatbed printers, and reciprocating cycle printers. Some of these printers use screw drive, and some use belt drive. For printers with screw drive, the production cost of the printer is virtually raised due to the high cost of the screw rod. In addition, the screw drive depends on the thread of the screw rod to push the printer forward, and the movement between the two objects produces a large impact. Sliding friction, so it needs to be equipped with a high-power motor for driving, which increases the production cost and the power loss of the motor virtually; the belt-driven printer, due to the extensibility ...

Problems solved by technology

For printers with screw drive, the production cost of the printer is virtually raised due to the high cost of the screw rod. In addition, the screw drive depends on the thread of the screw rod to push the printer forward, and the movement between the two objects produces a large impact. Sliding friction, so it needs to be equipped with a high-power motor for driving, which increases the production cost and the power loss of the motor virtually; the belt-driven printer, due to the extensibility of the belt, The printing speed cannot be synchronized with the driving speed, and the belt's expansion and contraction make the printing speed ahead of the driving speed for a while, and lag behind the driving speed for a while, and cannot form a certain regularity, which greatly reduces the printing speed and printing accuracy.
