Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is main TV structure schematic diagram of the present invention.
Fig. 2 is the plan structure schematic diagram of chase in the present invention.
In figure: the first conveying device 1, the section of climbing 11, lower slope section 12, backing roll 13, frame 2, chute 21, chase 3, silk-screen plate 31, screeding device 4, first cylinder 41, second cylinder 42, first scraper plate 43, second scraper plate 44, workpiece 5, the second conveying device 6, far infrared drying device 7, ultraviolet curing device 8.
Detailed description of the invention
As in Fig. 1,2, a kind of screen process press, comprises frame 2, and frame 2 is provided with chute, and chase 3 is slidably mounted in chute, and drives reciprocating motion by drive unit, and preferably, described chase 3 is moved back and forth by driven by servomotor.
Screeding device 4 is provided with above chase 3; In described screeding device 4, the first scraper plate 43 two ends are arranged in frame 2 by the first cylinder 41, and the second scraper plate 44 two ends are arranged in frame 2 by the second cylinder 42, and the first scraper plate 43 contacts with silk-screen plate 31 upper surface of chase 3 with the lower end of the second scraper plate 44;
First scraper plate 43 drives lifting by the first cylinder 41, and the second scraper plate 44 drives lifting by the second cylinder 42.Ink is located between the first scraper plate 43 and the second scraper plate 44, is also provided with the nozzle for carrying ink at this place.
The first conveying device 1 is provided with in the below of chase 3, a backing roll 13 is at least provided with below the top conveyer belt of the first conveying device 1, to make the position of top conveyer belt from backing roll 13 of the first conveying device 1, be divided into the section of climbing 11 and lower slope section 12, described backing roll 13 is positioned at below screeding device 4.Preferably, described backing roll 13 is positioned at the below of posterior second scraper plate 44.Structure thus, workpiece 5, only when scraper plate falls, contacts with the bottom of silk-screen plate 31, thus not easily by the spilling ink contamination bottom silk-screen plate 31, is more conducive to the printed patterns obtaining clear-cut margin.Forward and backward in this example, be as the criterion according to the traffic direction of workpiece 5, the position that workpiece 5 first arrives is front, after after the position that reaches is.
Preferably, the conveyor belt surface of the first described conveying device 1 is provided with multiple passage, and the inner space of conveyer belt is communicated with negative-pressure air fan.Structure thus, forms absorption affinity at conveyor belt surface, thus is convenient to the position of fixation workpiece 5, to guarantee that the position of pattern can not offset.
