Front parallel printing table plate movable counting and positioning mechanism

Abstract

The invention discloses a front parallel printing table plate movable counting and positioning mechanism. The mechanism comprises a frame, a transmission chain wheel, a driving device, a transmissionchain, a printing table plate, a counting chain wheel, a chain wheel bracket, a photoelectric switch, an induction plate and a proximity switch. The mechanism is skillful and reasonable in structuraldesign; in the working process, when the induction plate is operated to the proximity switch at normal speed, the proximity switch is triggered; at this time, a control system controls the driving device to reduce the speed; in the speed reducing state, when the induction plate moves to the photoelectric switch, the photoelectric switch is triggered; the outputting of the driving device is cut offby the control system; and the printing table plate is stopped, that is, the stop is performed after speed reduction, so that the influence on the positioning precision caused by higher inertia due to sudden braking is prevented, the positioning and conveying stability is effectively improved, meanwhile, the motion positioning error caused by the transmission chain gap is eliminated, and the repeated positioning precision is high; and in addition, the mechanism is compact and simple in overall structure and easy to realize, and facilitate wide popularization and application.

Description

technical field [0001] The invention relates to the technical field of printing platen movement and positioning, in particular to a front-parallel printing platen movement counting and positioning mechanism and a moving method thereof. Background technique [0002] The traditional screen printing table generally adopts fixed type and running table type. Although the substrate of the fixed screen printing platform can realize multiple overprints of a single color, the multiple overprints are completely based on the worker's visual inspection and the positioning block of the platen. Randomness directly affects the accuracy of overprinting. This method of printing cannot achieve continuous multiple printing, and it must wait for the printing ink to dry and then overprint again. The degree of automation is low, and the workers are greatly affected, so it can only be adapted to small batch production. The new front parallel printing platen moving structure can well solve the def...

[0002] The traditional screen printing table generally adopts fixed type and running table type. Although the substrate of the fixed screen printing platform can realize multiple overprints of a single color, the multiple overprints are completely based on the worker's visual inspection and the positioning block of the platen. Randomness directly affects the accuracy of overprinting

This method of printing cannot achieve multiple consecutive printings. It must wait for the printing ink to dry and then overprint again. The degree of automation is low and the workers are greatly affected, so it can only be adapted to small batch production.

The new front parallel printing platen moving structure can well solve the defects of fixed and running table printing machines, but due to the front parallel printing platen moving structure due to chain gaps and other reasons, the repeat positioning accuracy is relatively poor
