The above and/or additional aspects and advantages of the present invention will become apparent and readily appreciated from the following description of the embodiments, taken in conjunction with the accompanying drawings of which:
fig. 1 is a schematic structural diagram of a doctor blade according to an embodiment of the present invention.
Reference numerals:
1. a scraper;
10. a first doctor blade; 11. a first mating surface; 12. a step portion; 13. an installation part; 20. a second doctor blade; 21. a second mating surface.
Detailed Description
Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary.
A doctor blade 1 according to an embodiment of the invention is described below with reference to fig. 1.
As shown in fig. 1, a doctor blade 1 according to an embodiment of the present invention includes: a first doctor blade 10 and a second doctor blade 20. In the operation of the scraper 1, the first scraper blade 10 and the second scraper blade 20 can scrape the printing ink at the printing terminal back to the printing starting end and uniformly spread the whole screen plate, so that the ink amount is sufficient during printing, the printing interval time is shortened, and the phenomenon of screen blocking is avoided.
As shown in fig. 1, the first doctor blade 10 is provided with a first mating surface 11, the second doctor blade 20 is provided with a second mating surface 21, the first mating surface 11 and the second mating surface 21 mate, and the first doctor blade 10 is integrally formed on the second doctor blade 20. That is, the first mating surface 11 and the second mating surface 21 are closely fitted, and the first doctor blade 10 is integrally formed on the second mating surface 21 of the second doctor blade 20 via the first mating surface 11, so that the first doctor blade 10 and the second doctor blade 20 can form an integral structure without a gap between the first mating surface 11 and the second mating surface 21.
From this, first doctor blade 10 and second doctor blade 20 form a body structure, and do not have the clearance between first fitting surface 11 and the second fitting surface 21 in addition, easily introduce in the clearance between first fitting surface 11 and the second fitting surface 21 and remain the tin cream to be difficult to wash the remaining tin cream in the clearance, in addition, the dismantlement and the installation of first doctor blade 10 and second doctor blade 20 of being convenient for like this, need not dismantle first doctor blade 10, second doctor blade 20 and both sides and keep off the tin piece and wash.
Wherein, as shown in fig. 1, the size of the first doctor blade 10 is smaller than the size of the second doctor blade 20 in the first direction, and a stepped portion 12 is formed between one end of the first doctor blade 10 and one end of the second doctor blade 20. The stepped portions 12, i.e. the working portions of the first scraper blade 10 and the second scraper blade 20, which mainly scrape ink by the second scraper blade 20 during operation of the scraper 1, are more effective in scraping ink by the second scraper blade 20 alone than by the first scraper blade 10 and the second scraper blade 20.
As shown in fig. 1, in the first direction, the dimension a of the step portion 12 is in the range of: a is more than or equal to 2mm and less than or equal to 5mm. In the first direction, the size of the step 12 needs to be within a reasonable range, and the size of the step 12 should not be too small, i.e. less than 2mm, so that ink can be prevented from being smeared on the first doctor blade 10 when ink is scraped, and of course, the size of the step 12 should not be too large, i.e. more than 5mm, so that the overall strength of the step 12 is reduced, and the step 12 is damaged when the second doctor blade 20 scrapes ink when the force is too large.
Further, as shown in fig. 1, in the second direction, the dimension b of the second doctor blade 20 is in the range of: b is more than or equal to 0.15mm and less than or equal to 0.20mm, and the second direction is vertical to the first direction. In a second direction perpendicular to the first direction, the size of the second scraper blade 20 needs to be within a reasonable range, the size of the second scraper blade 20 cannot be too small, i.e. smaller than 0.15mm, so that the end of the second scraper blade 20 is too sharp, and when the second scraper blade 20 scrapes ink, other components are easily scraped, of course, the size of the second scraper blade 20 cannot be too large, i.e. larger than 0.20mm, so that the end of the second scraper blade 20 is thick, and the ink scraping effect is poor. The dimension of the second doctor blade 20 in the second direction is preferably 0.15mm.
According to an alternative embodiment of the invention, as shown in fig. 1, the other end of the first scraper blade 10 and the other end of the second scraper blade 20 are located in the same plane, and the other end of the first scraper blade 10 and the other end of the second scraper blade 20 form a mounting 13. The other end of the first doctor blade 10 is located in the same plane as the other end of the second doctor blade 20, i.e. the other end of the first doctor blade 10 is flush with the other end of the second doctor blade 20 in the second direction, so that the mounting portion 13 can be mounted and fixed better after the mounting portion 13 is formed at the other end of the first doctor blade 10 and the other end of the second doctor blade 20.
In addition, as shown in fig. 1, in the second direction, the dimension of the mounting portion 13 is c, and the range of c is: c is more than or equal to 0.3mm and less than or equal to 0.4mm. In the second direction, the size of installation department 13 needs be in reasonable scope, and the size of installation department 13 can not be too little, is also less than 0.3mm, and when installation department 13 was installed like this, relatively poor to the fixed effect of installation department 13, installation department 13 appears becoming flexible easily, and of course, the size of installation department 13 also can not be too big, also is more than 0.4mm, and installation department 13 is too big in the second direction's size like this, and installation department 13 is difficult to install fixedly.
Of course, the doctor blade 1 also comprises: the installation shell, the installation shell is provided with the draw-in groove, and installation department 13 card is located in the draw-in groove. The installation shell mainly can play the fixed effect of installation, is provided with the draw-in groove on the installation shell, can locate installation department 13 card in the draw-in groove like this, and fixed mounting department 13 is through the mode of installation department 13 with the draw-in groove joint moreover, and first scraper blade 10 and second scraper blade 20 are more simple and convenient with the installation and the dismantlement of installation shell, are convenient for wash first scraper blade 10 and second scraper blade 20.
Alternatively, the first doctor blade 10 and the second doctor blade 20 are each one of a stainless steel doctor blade 1 and a high carbon steel doctor blade 1. That is to say, the material of first scraper blade 10 and second scraper blade 20 can be one of stainless steel and high carbon steel, and stainless steel and high carbon steel all are applicable to circuit tin cream printing of scraping, and the die sinking cost is lower, can reduce design development cost to the film change of appearance and mesh, and stainless steel and high carbon steel have very high corrosion resistance in addition, and the plasticity is better, and the weldability is good, and toughness is high under the low temperature, in addition, does not have magnetism, easy work hardening.
Further, the surfaces of the first doctor blade 10 and the second doctor blade 20 are also plated with ceramic layers. The surfaces of the first doctor blade 10 and the second doctor blade 20 are also coated with ceramic layers, so that the doctor blade 1 is good in anti-sticking effect, and can obtain high hardness after heat treatment, and has good wear resistance and machinability.
According to the utility model discloses printing machine, include: doctor blade 1 as described in the previous embodiment.
