Fig. 1 to Fig. 6 shows the structural schematic diagram of anti-drip mechanism provided by the utility model.
It please refers to Fig.1, Fig. 2 and Fig. 4, now anti-drip mechanism provided by the utility model is illustrated.Anti-drip mechanism,
For screen process press, including rack 1, it is rotationally connected with the rotation seat 2 of rack 1 and returns ink assembly connecting seat 7, is connected to rotation
The drive component 4 of seat 2 scrapes ink assembly 3 and set on time ink assembly 6 returned on ink assembly connecting seat 7 on rotation seat 2.
Rotation seat 2 include with it is described scrape moving block 21 that ink assembly is connect and connect with moving block 21 for driving moving block 21 to rotate
Connecting rod 22, connecting rod 22 and drive component 4 are rotatablely connected.
The operation principle of anti-drip mechanism that the utility model embodiment provides is：When being worked, drive component 4 pushes away
Ink assembly 3 of scraping on dynamic or pulling rotation seat 2 and rotation seat 2 is rotated；When carrying out back ink, the rise of ink assembly 3 is scraped, is returned
Ink assembly 6 is fallen, and ink assembly 3 is scraped in the driving of drive component 4, is made to scrape ink assembly 3 and is turned to a limit position, scrapes ink assembly 3 at this time
Positioned at the oblique upper for returning ink assembly 6, it is sticked to the ink scraped on ink assembly 3 and drops onto back on ink assembly 6, to avoid directly dripping to
It is damaged on printing substrate and to printing substrate；When carrying out wiping, returns ink assembly 6 and rise, scrape ink assembly 3 and fall, drive
The driving of component 4 scrapes ink assembly 3 and turns to another limit position, scrapes ink assembly 3 at this time and is contacted with halftone, proceeds by wiping and appoints
Business.
The ink assembly 3 of scraping of anti-drip mechanism provided by the utility model is connected to rotation seat 2, and rotation seat 2 includes and wiping
The moving block 21 that component 2 connects and the connecting rod 22 being connect with moving block 21, with turn by drive component 4 drives connecting rod 22
Motion block 21 rotates, in turn, at the end of wiping, scrape ink assembly 3 by moving block 21 drive its turn to back ink assembly 6 it is oblique on
Side, so that the residual ink scraped on ink assembly 3 drops to back on ink assembly 6.This rotational structure for scraping ink assembly 3 relative to gear with
For rack matches resultant motion in a manner of realizing and scrape the rotation of ink assembly 3, have the advantages that not easy to wear, stationarity is good, and by
It is not easy to wear in it, it is ensured that long-time service do not interfere with cooperation precision, in addition, the structure also have it is easy to process, be easy to
The advantages that implementing and be at low cost.

It can lead to entire anti-drip structural failure because of unbalance stress.
Further, it please refers to Fig.1, Fig. 2, Fig. 3 and Fig. 6, anti-drip mechanism further includes for adjusting the pole for scraping ink assembly 3
The adjusting part 5 of rotation angle is limited, adjusting part 5 includes adjusting bolt 51 and the locking nut with the mating connection of adjusting bolt 51
52, moving block 21 is equipped with positioning surface 211, and fixed block 11 is equipped with the threaded hole being connected with locking nut 52.Adjusting bolt 51
Contacted with positioning surface 211 after threaded hole, adjusting bolt 51 pass through threaded hole length it is adjustable so that moving block 21 rotation
Adjustable angle, then locking nut 52 adjusting bolt 51 is locked in rack 1.
For the wiping effect reached, scraping when ink assembly 3 is contacted with halftone should be a certain included angle.Add above-mentioned tune
After saving component 5, when work, the end of adjusting bolt 51 has position-limiting action to the positioning surface 211 on moving block 21, i.e., to close
The direction of positioning surface 211 rotates adjusting bolt 51, can reduce the extreme angles for scraping the rotation of ink assembly 3, if to remotely located face
211 direction rotates adjusting bolt 51, then can increase the extreme angles for scraping the rotation of ink assembly 3.In this way, to different printings
When material is printed, adaptability adjusting can be carried out to limit rotation angle according to different technological requirements, to reach good
Printing effect.
Further, Fig. 2 and Fig. 3 and Fig. 4 are please referred to, the connecting hole that fixed rotating shaft 12 and moving block 21 are rotatablely connected is logical
Hole, the both ends that fixed rotating shaft 12 stretches out moving block 21 are equipped with dial 121, moving block 21 be equipped with for dial 121
The reference identification of cooperation.When work, fixed rotating shaft 12 and dial 121 are fixed, and moving block 21 is around 12 turns of fixed rotating shaft
It is dynamic.When moving block 21 rotates to different angle, the specific scale for the reference identification alignment dial 121 being equipped with.Cause
This, when the rotation extreme angles for scraping ink assembly 3 are adjusted, can with the scale value on dial 121 be with reference to
Quantitative adjusting is carried out to the limit rotation angle of moving block 21, to keep adjusting more accurate.
Further, it please referring to Fig.1 and Fig. 4, the quantity of fixed block 11, moving block 21 and adjusting part 5 is respectively two,
