Abstract
A kind of doctor knife rest, including wiping tool holder body, straight through tube is equipped in the top of the wiping tool holder body, the end of the straight through tube is connected with inlet tube, angle β=30 80 ° of the nozzle holes of strip, the nozzle holes and straight through tube are evenly equipped in the wiping tool holder body of the straight through tube lower part.The utility model, which not only has, rinses the advantages of area is big, and washing time is short, moreover it is possible to ensure that the clean degree rinsed is higher, it is simple in structure, and it is easy to operate.
Description
Technical field
The utility model is related to a kind of ink printing equipment, particularly a kind of doctor knife rest.
Background technology
At present in printing equipment field, due to flexible version printing be suitable for it is various flexible, rigid and shaggy hold
Material and relatively low, with short production cycle, the flexible flexible relief printing plate of production cost are printed to there is the features such as anilox roll inking,
In high volume, it is had broad application prospects in large-scale production.In flexible version printing, it is desirable to it is beautifully printed, printing machine
In must generally be furnished with the doctor blade system of cavate type, since wiping knife rest room and anilox roll need to clean, and existing cleaning
As shown in Figure 1, the water from water inlet system out mainly either vertically pours mode from ink entrance from ink wash pipeline
Cleaning area cutter setting frame is rinsed, and washing time is longer and the clean degree rinsed needs to be further improved, and rinses
Process is subsequent very big using influencing on its, therefore how to provide the doctor knife that a kind of washing time is short, degree of rinsing well is higher
Frame is one of those skilled in the art's major issue urgently to be resolved hurrily.
Utility model content
A kind of doctor knife rest is provided the purpose of the utility model is to overcome the above-mentioned insufficient of the prior art, it not only has
Have and rinse the advantages of area is big, and washing time is short, moreover it is possible to ensure that the clean degree rinsed is higher, it is simple in structure, it is easy to operate.
The technical solution of the utility model is：A kind of doctor knife rest, including wiping tool holder body, the wiping knife rest sheet
Straight through tube is equipped in the top of body, the end of the straight through tube is connected with inlet tube, the wiping of the straight through tube lower part
β=30-80 ° of the angle of the nozzle holes of strip, the nozzle holes and straight through tube is evenly equipped in tool holder body.
As a further improvement of the above technical scheme：The angle β of the nozzle holes and straight through tube is preferably 40 °.
Further, the one side of the wiping tool holder body is bulge-structure, and the middle part of bulge-structure is equipped with trapezoidal recessed
Slot.
Further, the upper and lower both sides of the trapezoidal groove are arranged with doctor, at the blade of two doctors with
Same reticulate pattern ink is tangent, forms closed space between two doctors, reticulate pattern mill and trapezoidal groove three, the confined space
Inside there is the flowing of ink or ink wash water, the doctor is fixed using blade pressuring plate, and the straight through tube is arranged on
The side of the doctor of side, the nozzle holes direction be both neither perpendicular to nor parallel to doctor direction, had made from nozzle
Cleaning solution in hole out carries out tilting to doctor and washes away, not only clean by fast flush conducive to doctor, but also is avoided that
Cleaning solution vertically washes away the influences such as the damage with doctor for a long time.
Further, the nozzle holes direction and angle folded by nearest doctor direction are acute angle.
Further, the nozzle holes form two along the symmetrical distribution of the wiping knife rest body central line
The flush clean in direction, conducive to cleaning efficiency is improved.
Further, the both ends of the straight through tube have matched inlet tube, have both shortened cleaning solution and have entered nozzle holes
In time, and straight through tube can be reduced and enter spray to entering the Weaken degree of the cleaning solution kinetic energy in nozzle holes, guarantee
Cleaning solution kinetic energy rejection in nozzle hole is smaller, and then conducive to raising cleaning quality.
The utility model has following features compared with prior art：
（1）Nozzle holes by being designed to the inclination with straight through tube acute angle formula by the utility model, from straight through tube
The flushing surface that cleaning solution out is formed is more much larger than the flushing surface of formation of the nozzle holes with straight through tube when vertical, both can guarantee
It is more to the wash number of same place within the equal time, conducive to cleaning quality is improved, and can guarantee that cleaning surface is wider, make every
A corner can be cleaned, and can also improve whole cleaning quality；On the other hand, cleaning area is larger, reaches phase
With cleannes when can also greatly shorten scavenging period；
（2）The utility model greatly improves cleaning performance by changing the direction that opens up of nozzle holes to realize, there is no increase
Add new structure, simple in structure, improving cost is relatively low, and use is also very convenient.
The detailed construction of the utility model is further described below in conjunction with the drawings and specific embodiments.
Description of the drawings
Fig. 1 is the structure diagram when wiping knife rest of the prior art uses；
Fig. 2 is the structure diagram of the utility model；
Fig. 3 is the structure diagram of the wiping tool holder body of the utility model；
Fig. 4 is the structure diagram when wiping tool holder body of the utility model uses.
Marginal data：
1st, wiping tool holder body；11st, trapezoidal groove；2nd, straight through tube；3rd, inlet tube；4th, nozzle holes；5th, doctor；6th, net
Line ink；7th, blade pressuring plate.
Specific embodiment
As shown in attached drawing 2, attached drawing 3, a kind of doctor knife rest, including wiping tool holder body 1, wiping tool holder body 1 it is upper
It is equipped with straight through tube 2 in portion, the end of straight through tube 2 is connected with water inlet pipe 3, in the wiping tool holder body of 2 lower part of straight through tube
It is evenly equipped with the nozzle holes 4 of strip, nozzle holes 4 and angle β=40 ° of straight through tube 2；Nozzle holes 4 are along wiping tool holder body 1
The symmetrical distribution of center line；The both ends of straight through tube 2 have matched water inlet pipe 3.
The one side of wiping tool holder body 1 is bulge-structure, and the middle part of bulge-structure is equipped with trapezoidal groove 11；Trapezoidal groove
11 upper and lower both sides are arranged with doctor 5, at the blade of two doctors 5 with black 6 tangent, the doctors 5 of same reticulate pattern
Be fixed using blade pressuring plate 7, the side of doctor 5 that straight through tube 2 is disposed over, 4 direction of nozzle holes with
Angle folded by nearest 5 direction of doctor is acute angle.
From attached drawing 1 it can be seen that when old-fashioned knife rest injects high-pressure cleaning liquid by inlet tube in the prior art, from nozzle
The cleaning solution spray width sprayed in hole 4 is B；It can be seen that novel doctor frame provided by the utility model from attached drawing 4
When injecting high-pressure cleaning liquid by inlet tube, the cleaning solution spray width that is sprayed from nozzle holes 4 is A, it is evident that find out A
Value is far longer than B values, so as to show that the cleaning performance of the utility model is more preferable.
