Abstract

The utility model relates to a printing ink scraper for screen printing, which comprises a scraper holder and a scraper head, the scraper holder can hold the scraper head; wherein, the scraper head comprises a first scraping side, a bottom side and a second scraping side, a groove is arranged on the bottom side where one of the first scraping side and the second scraping side is near, which is used for avoiding the remaining printing ink to drop on the screen in printing ink recycling process.

Description

Ink knife

[technical field]

The utility model relates to a kind of ink knife that is used for screen painting.

[background technology]

Screen painting (Screen Printing) is one of printing four big methods, claims porous printing or serigraphy again, and it is applicable to the article of various material difference, out-of-shape or surface irregularity, applied range.

During screen printing apparatus work, can be divided into Hui Mo, printing substantially and receive three main processes of China ink, promptly earlier with the excessive oil ink droplet on the half tone and utilize scraper gently to scrape half tone printing ink is uniformly coated on (Hui Mo) on the half tone, utilize scraper to scrape half tone once more then printing ink is printed to printed material (printing) by mesh, utilize scraper gently to scrape half tone at last and residual ink is reclaimed (receiving China ink).

Scraper is one of main tool of screen painting, and it comprises scraper group and two kinds of structural designs of single scraper, and manually board generally uses single scraper to finish screen painting.For cooperating different printed materials, that the pattern of scraper has is monolateral, V-type, circle and square etc., and printed material is planar object such as paper, can select square scraper for use, if printed material is clothing, cloth etc., can select circle or V-type scraper for use, can increase the ink bleed amount.

A kind of prior art ink knife as shown in Figure 1, this ink knife 10 comprises a scraper holder 11 and a scraper head 12, this this scraper head 12 of scraper holder 11 clampings.This scraper head 12 is a rectangular solid, comprises two parallel shaving 13,15 and bottom surfaces 14, and shaving 13, bottom surface 14 are linked in sequence with shaving 15, and shaving 13,15 is vertical with bottom surface 14 respectively.

Please refer to Fig. 2, the user mode figure when being prior art ink knife 10 receipts China inks.Under transmission mechanism (figure does not show) transmission, ink knife 10 was scraped half tone 16 and was reclaimed residual ink 17.Scraper head 12 contacts with half tone 16 and reaches speed at a certain angle and at the uniform velocity scrapes, and residual printing ink 17 will be struck off withdrawal.But the space (sign) that printing ink 17 can form at the shaving 13 and the half tone 16 of scraper head 12 is built up, and make printing ink 17 be not easy to reclaim, and possible residual titration half tone 16, causes waste and pollution, will shorten the service life of half tone 16.

[utility model content]

Receive the relatively poor problem of black effect for solving the prior art ink knife, the utility model provides a kind of and is convenient to receive China ink and receives China ink ink knife reliably.

The technical scheme that the utility model technical solution problem adopts is: a kind of ink knife is provided, it comprises a scraper holder and a scraper head, this this scraper head of scraper holder clamping, this scraper head comprises one first shaving, a bottom surface and one second shaving, is provided with groove in first shaving and one of them adjacent floor place of second shaving.

Compared with prior art, the utlity model has following advantage: be used to receive black shaving adjacent floor place at ink knife and be provided with a groove, provide temporary storage location for residual ink when receiving China ink, hold the printing ink space and become big, make recovery printing ink easier, also avoid printing ink to build up and the residual titration half tone.

[specific embodiment]

Please refer to Fig. 3, is the schematic perspective view of the utility model first embodiment ink knife 100.This ink knife 100 comprises a scraper holder 110 and a scraper head 120, this this scraper head 120 of scraper holder 110 clampings.Wherein, this scraper holder 110 can be made by metallic aluminium low by price, that material is light, and this scraper head 120 is mainly made by rubber, and mixes a small amount of other composition to change the character of hardness and chemically-resistant solvent.This scraper head 120 is roughly an irregular rectangular solid, it comprises one first shaving 121, a bottom surface 123 and one second shaving 124, this first shaving 121 be arranged in parallel with this second shaving 124, and this first shaving 121, bottom surface 123 and this second shaving 124 are linked in sequence.These first shaving, 121 adjacent floor, 123 places are provided with groove 122, and the face (not shown) of this groove 122 is a circular arc, are that residual ink (figure does not show) provides a temporarily providing room when receiving China ink.

See also Fig. 4, the user mode figure when being the utility model first embodiment ink knife 100 receipts China inks.Under transmission mechanism (figure does not show) transmission, scraper holder 110 clamping scraper heads 120 were scraped half tone 105 and were reclaimed residual ink 104, and wherein, this half tone 105 is horizontal positioned.First shaving 121 of scraper head 120 contacts with half tone 105 with the angle of bottom surface 123, and scraper head 120 keeps certain angle with half tone 105, and this angle can be 40 degree to 75 degree, and at the uniform velocity scrapes half tone 105 with certain speed, and residual printing ink 104 will be recovered.The printing ink 104 that groove 122 provides certain space can keep in recovery avoids printing ink 104 to build up.

Seeing also Fig. 5, is the side view of the utility model second embodiment ink knife 200.This ink knife 200 comprises a scraper holder 210 and a scraper head 220, this this scraper head 220 of scraper holder 210 clampings.Wherein, this scraper head 220 is roughly an irregular rectangular solid, it comprises one first shaving 221, a bottom surface 223 and one second shaving 224, and this first shaving 221 be arranged in parallel with this second shaving 224, and this first shaving 221, bottom surface 223 and this second shaving 224 are linked in sequence.Be used to receive black shaving 221 adjacent floor 223 places and be provided with a wedge-shaped impression 222, groove 222 comprises a first surface 225 and a second surface 226.This first surface 225 intersects with this shaving 221, and this second surface 226 intersects with this bottom surface 223, and angle is less than 90 degree.Groove 222 provides a temporarily providing room (not indicating) printing ink residual titration in the time of can avoiding receiving China ink.
