Transmission device of automatic round-surface screen printing machine

Abstract

The invention provides a transmission device of an automatic round-surface screen printing machine, belonging to the field of mechanical technology and solving the problems of low printing efficiency and poor printing quality of the traditional automatic round-surface screen printing machine. The transmission device of the automatic round-surface screen printing machine is arranged on a stand of a screen printing machine and comprises a motor and a transmission shaft driven by the motor, wherein a transmission mechanism I is arranged between a screen printing ink box and the transmission shaft and can drive the screen printing ink box to reciprocate along a horizontal direction when the transmission shaft rotates, the transmission shaft is further provided with a jacking mechanism capable of jacking a workpiece on a transmission chain onto the screen printing ink box when the transmission shaft rotates, the transmission shaft is also fixedly connected with a chain wheel I, the stand is provided with a slicer, the chain wheel I and an input shaft of the slicer are provided with a transmission mechanism II capable of driving the input shaft of the slicer to rotate when the transmission shaft rotates, and a transmission mechanism III is arranged between an output shaft of the slicer and a main chain wheel and can drive the main chain wheel to rotate when the output shaft rotates. The transmission device provided by the invention has the advantages of high printing efficiency, good printing quality and the like.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to an automatic circular screen printing machine, in particular to a transmission device in the automatic circular screen printing machine. Background technique [0002] As a kind of printing equipment, screen printing machine has been widely used in various medical applications such as the printing of surface graphics on syringes. The circular screen printing machine is to print on the cylindrical surface of an item with a cylindrical surface. [0003] The existing syringe scale line screen printing machine is a kind of circular screen printing machine. The syringe is conveyed to the bottom of the silk screen ink cartridge through the transmission chain, and then driven by the transmission mechanism to lift the syringe to the silk screen ink cartridge. The silk screen ink cartridge Driven by the transmission mechanism, it moves left and right, and the scraper moves downward to scr...

Problems solved by technology

[0005] However, in the above-mentioned patent, the transmission of power from the transmission shaft to the sprocket adopts a sheave mechanism. The transmission shaft drives the pin wheel to rotate, and hits the sheave to complete the intermittent rotation of the sheave. This structure causes the screen printing machine to be impacted. The force is relatively large, which will form a large impact force on the transmission shaft, sprocket, etc., and the vibration will be large, affecting its service life. The noise generated is also large, and it is easy to cause the transmission of the workpiece to be unstable. big limit

In order to reduce the impact force, lubricating oil must be installed between the pin wheel and the sheave for a long time. At present, the most common method is to erode the sheave in the oil tank full of lubricating oil, which will cause the pollution of the lubricating oil to the entire transmission system Larger, and the oil needs to be replaced frequently, which wastes manpower and material resources

In addition, when the jacking mechanism lifts the workpiece from the conveyor chain to the screen printing ink cartridge, due to vibrations and other effects, the workpiece may deviate when it is lifted to the position of the ink cartridge. Especially when the machine is running at a high speed, the deviation of the workpiece position will cause printing Offset position, poor printing quality
