Description
Technical Field
The invention belongs to the technical field of metal processing, and relates to a multi-point surface spray printing method.
Background
The multi-point surface spraying in the middle plate factory is a spray printing device for spraying and printing marks on the surface of a steel plate after paint spraying according to certain arrangement requirements. When the thickness of the steel plate exceeds 16mm, ink leakage of individual spray needles often occurs, and the ink leakage still occurs at the position of the steel plate when the ink is repeatedly sprayed, so that the spray printing is unclear. It is not effective to replace the nozzle needle, seal ring, nozzle, coil, etc. or the jet printing assembly.
The remanence instrument is used for measuring the position with the spray printing mark on the steel plate, and when the remanence instrument displays more than about 30mT through repeated verification of a plurality of steel plates, ink leakage occurs when the steel plate at the corresponding position is subjected to spray printing. Cause of remanence on steel plate: the steel plate is lifted to the position of the spray printing through the magnetic disc crane, residual magnetism can be generated on the steel plate at the position of contact with the magnetic disc crane, and the residual magnetism is larger when the thickness of the steel plate is thicker.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a method for solving ink leakage of multi-point surface spraying.
The invention specifically adopts the following technical scheme:
a method for solving ink leakage of multi-point surface jet is characterized in that: a plate made of an electromagnetic absorption material is arranged below a nozzle of the jet printing equipment; arranging a through hole corresponding to the position of a nozzle of jet printing equipment on the plate, wherein the aperture of the through hole is larger than the outer diameter of the nozzle of the jet printing equipment, so that the position of the nozzle has an adjustment margin and jet printing is smooth; when in spray printing, the plate is fixed, so that the nozzle head of the spray printing equipment penetrates through the through hole on the plate to perform spray printing.
When the method is adopted for spray printing, ink leakage can not occur when the residual magnetism of the steel plate reaches 90mT, the spray printing quality is greatly improved, and the production efficiency is improved.

Fig. 1 is a schematic structural diagram of a multipoint table spraying device.
Detailed Description
The present invention is described in further detail below with reference to specific embodiments and the attached drawings.
As shown in fig. 1, when multi-point surface jet printing is performed, the coil 3 is electrified to enable the armature sleeve 4 to generate magnetism, so that the armature 2 compresses the spring 5 to drive the needle 6 to move upwards, a gap is formed between the needle 6 and the nozzle 7, and ink is ejected from the nozzle to perform jet printing; after the jet printing is finished, the coil 3 loses power to lose magnetism and lose suction force of the armature sleeve 4, the armature 2 drives the spray needle 6 to move downwards under the action of the spring 5, the spray needle 6 seals the nozzle 7, ink does not leak from the nozzle 7, and the jet printing action is finished. The adjusting rod 1 is used for adjusting the size of the nozzle opened by the spray needle, so that the effect of adjusting the size of ink dots is achieved.
The ink leakage at the residual magnetism position on the steel plate is caused by the following reasons: the force generated by the residual magnetism on the steel plate is not so large as to automatically open the spray needle, so the action during spray printing is normal; after the jet printing is finished, the coil 3 is not electrified to lose magnetism and lose attraction force of the armature sleeve 4, but the armature sleeve 4 is magnetized to generate magnetism due to the magnetism on the steel plate, so that magnetic force is generated on the armature 2, the magnetic force still enables the armature 2 to overcome the downward acting force of the spring 5, the nozzle 7 cannot be completely sealed by the spray needle 6, and ink leakage can be generated at the nozzle 7.
The method for solving the ink leakage of the multi-point surface jet printing comprises the step of arranging a plate 8 made of electromagnetic absorption materials with the thickness of 6-8mm below a nozzle of jet printing equipment, wherein the plate is used for absorbing residual magnetism on a steel plate hoisted to a jet printing position through a magnetic disc. Because the residual magnetism on the steel plate is generally not too large, a 6mm thin plate is preferred, the strength and the weight are small, and the magnetic isolation effect can be realized. If the plate is too thick, exceeding 8mm, the weight is too heavy and the distance between the plate and the steel plate to be jet-printed is too short, which is not favorable for the jet-printing operation. The plate made of the electromagnetic absorption material in the embodiment can be made of local materials, and the magnetic absorption can be realized by adopting a steel plate. The magnetic absorption plate is provided with a through hole corresponding to the position of the nozzle of the jet printing equipment, and the aperture of the through hole is 1.5-2mm larger than the outer diameter of the nozzle of the jet printing equipment, so that the position of the nozzle has adjustment allowance and the jet printing is smooth. If the aperture is too small, the requirements on the accuracy of the processing position and the size error on the steel plate hole are very high, otherwise, ink dots can be blocked by the steel plate, and if the aperture is too large, the magnetic isolation effect cannot be achieved.
When in spray printing, the magnetic absorption plate is fixed by using a support and the like, so that the nozzle head of the spray printing equipment can pass through the through hole on the plate to perform spray printing on the steel plate. At the moment, the magnetism of the magnetic disk hoisted to the steel plate at the spray printing position is absorbed by the increased 6-8mm steel plate, and the residual magnetism on the original steel plate can not act on the armature sleeve 4, so that the magnetic force can not be generated, and the spray printing work can be normally carried out.
