Abstract
A rotary screen scraper for improving stability of slurry feeding quantity is provided with a first straight-line segment, a second straight-line segment, a third straight-line segment and a fourthstraight-line segment, a plurality of mounting holes are reserved at symmetric positions of a portion between the second straight-line segment and the third straight-line segment on the rotary screen scraper, an auxiliary part is fixedly mounted on a side wall of the rotary screen scraper through a bolt, and the shape of the auxiliary part is totally identical to that of a portion between the first straight-line segment and the third straight-line segment on the rotary screen scraper or of a portion between the first straight-line segment and the fourth straight-line segment on the rotary screen scraper. Dimensional stability can be better maintained under interaction of the rotary screen scraper and slurry, straightness of a blade is maintained particularly, descending amount consistence of rotary screens at equivalent position is benefitted, possibility of slurry skinning and screen clogging is decreased, and accordingly finished product qualified rate of wallpaper is increased. Besides, continuous production of rotary screen printing is benefited, and productive rate and finished product qualified rate are improved.
Description
Technical field
The utility model belongs to mechanical field, relates to a kind of cylinder scraper that improves lower slurry amount stability.
Background technology
ROTARY SCREAM PRINTING is operation stage most important, the most complicated in the wallpaper production link.The most essential work of ROTARY SCREAM PRINTING link with accurate, lifelike being presented on the wallpaper base material of designers's pattern intention.Yet, have a greatly reduced quality because the multilateral coordinated of this operation stage makes final effect.Impact as wallpaper base material character, flatness and the uniformity; The impact of Stability of Slurry; Whether the integrity of cylinder equipment itself as there being the impacts such as folding line; Complexity, the thickness of lines and technical staff's the operation consummation etc. of pattern flower type all directly affect the effect of ROTARY SCREAM PRINTING.
As the production technology personnel of ROTARY SCREAM PRINTING link, more energy are that flower is in influence factor that this link was directly involved in such as the qualification of cylinder equipment and personnel operation.The cylinder doctor blade system is the chief component of cylinder equipment, and the doctor sheet is the core of doctor blade system, and the stability of doctor sheet directly affects the suffered pressure of slurry everywhere, thereby impact respectively is equal to the uniformity of slurry under pattern position.Existing doctor sheet is about 1 meter, wide approximately 10 centimetres (with approximately 5 centimetres of the interactional width of slurry), thick approximately 1 millimeter.Such bar blade is difficult to guarantee keep glacing flatness preferably in the use procedure of long period, thereby is difficult to guarantee respectively to be equal to the uniformity of slurry under pattern position, reduces the qualification rate of finished product; This doctor blade system does not possess stronger heat-sinking capability (scraper and slurry acutely rub and produce high heat) yet simultaneously, has increased the possibility of slurry network blocking.
The utility model content
The purpose of this utility model is to provide a kind of cylinder scraper that improves lower slurry amount stability.
The technical scheme that adopts is:
On a kind of cylinder scraper that improves lower slurry amount stability, the first straightway, the second straightway, the 3rd straightway and the 4th straightway are arranged, part between the first straightway on the cylinder scraper and the second straightway, embed in use in the doctor blade system fixture, between the second straightway on the cylinder scraper and the 3rd straightway, part contacts with slurry, and between the 3rd straightway on the cylinder scraper and the 4th straightway, part is cylinder scraper blade;
Offer respectively a plurality of installing hole (see figure 1)s on the symmetric position of part between the second straightway on the cylinder scraper and the 3rd straightway, be bolted on a sidewall of cylinder scraper and be equiped with auxiliary member, between the first straightway between the first straightway on the shape of auxiliary member and cylinder scraper and the 3rd straightway on part or cylinder scraper and the 4th straightway, the shape of part is identical, in order to increase the thickness of scraper;
Described bolt is metal material, polytetrafluoroethylene (PTFE) or plastic material;
Described installing hole is circular, and diameter is between the 5-10 millimeter;
Described installing hole quantity is two or more, is evenly distributed between the second straightway on the cylinder scraper and the 3rd straightway on part;
Described auxiliary member material is polyethylene, polytetrafluoroethylene (PTFE), stainless steel or metallic aluminium;
The thickness range of described auxiliary member is the 0.5-10 millimeter;
Between the 3rd straightway on above-mentioned cylinder scraper and the 4th straightway, the width of part is the 1-20 millimeter.
The utlity model has following advantage:
1) with the interaction of slurry under can better keep DIMENSIONAL STABILITY, especially keep the glacing flatness of blade, this is conducive in the equivalent site of cylinder slippage consistent;
2) increase of blade thickness is beneficial to heat conduction, and this is conducive to scraper and the fricative heat of slurry are in time got rid of, and reduces the possibility of slurry conjunctiva, network blocking, thereby improves the product qualified rate of wallpaper;
3) greatly reduce the probability of network blocking, be beneficial to the serialization production of ROTARY SCREAM PRINTING, improved productive rate and product qualified rate.
