Description

Printing material clamp and printing device on printing manuscript

Technical Field

The invention relates to the technical field of seal cutting, in particular to a printing material clamp and a printing device on a printing manuscript.

Background

Seal cutting art is a popular art which has been spread in 3700 years as one of four traditional arts of 'poetry, painting and calligraphy' and is a life-oriented art which is a credence for exercising power, symbolizing status and proving personal identity.

The first step of the seal cutting enthusiasts to learn seal cutting is to exercise and imitate the seal cut by the predecessor, namely, the seal in the printing chart, to feel the book and knife interest of seal cutting. Meanwhile, the seal seeking in the seal is the mainstream seal cutting creation method at present, namely, the ancient seal is simulated, one character or two characters in the seal seeking creation method are changed, a seal is designed on paper, then the copy paper is used for sketching, and then stone burning is carried out, so that the ancient seeking in the seal ancient is realized.

The first step of imitating ancient typography is to mirror the image in the print onto the print material and then print the print in the trace, which is called the print stone. The traditional process of coating the stone on the manuscript comprises the complex processes of copying a printing spectrum by manual copy paper, overturning, aligning and fixing the copy paper and the printing stone, coating the penetrating ink into the stone by essential balm, airing, taking off and the like.

The process of tracing the print by using one stroke of the writing brush takes a lot of time, and ink easily flows to contaminate the precious print. The process of aligning, taking water or organic solvent to permeate the ink marks on the copy paper into the printing material has extremely high failure rate, often has the problems of line shift and blurring, unclear handwriting, easy erasing in the seal cutting process and the like, and meanwhile, for some materials with higher density such as jade and the like, stone feeding becomes more difficult. The seal cutting enthusiasts are caused with lots of troubles and workload, and some seal cutting beginners lose interest and patience in seal cutting.

Some supplementary devices and commodities of going up stone have appeared in the market now, for example the seal paste, a sticker with the seal drawing pattern can paste on the seal stone, makes things convenient for seal cutting fan to carry out the seal cutting according to the vestige on the seal paste, but can leave the plastic film of a layer of tape glue layer on the seal stone surface, has influenced the lithology on seal stone surface, appears and glues sword, adhesion, skinning scheduling problem. The special refreshing feeling generated by the extrusion and collision of the diamond is influenced. Meanwhile, the problems that the bought seal is single, can only be used once, cannot meet the requirement of independent creation of seal stones and the like exist.

There is also disclosed a stamp attaching apparatus, as disclosed in patent publication No. CN204687698U, which is adapted to cut a stamp image on a rubber stamp material in a reverse direction by a numerically controlled machine tool, and then attach a pad to a stamp pad to attach the stamp pad and attach the pad to the stamp pad as a stamp. Although the method can be used for a plurality of times on the surface, the same stamp can cover a plurality of times, but the cost is higher, the process of making the stamp is more troublesome, the diversity of the stamp is limited, and the problem of easy erasing is not solved by the inkpad material.

Secondly, traditional manual carving seal has the inevitable carving slowly, carves badly easily, and sculpture inefficiency, and some seals carry out mechanical seal cutting through equipment in addition, but does not set up supporting anchor clamps, leads to seal cutting characters figure on the seal to take place to deviate easily, and mechanical fixture knocks the seal material easily, increases defective percentage and manufacturing cost.

The traditional printing bed pushes a wood block to extrude a printing material to be fixed through wedge-shaped wood extrusion or bolt rotation, and although the basic clamping function is met, the traditional printing bed is not suitable for the environment needing mechanical operation and needs accurate three-dimensional angle positioning, thereby avoiding complex tool setting and focusing work. Patent document No. CN203543489U discloses a fixture for seal cutting worktable, which improves some defects, but can not meet the requirement of three-axis angle positioning, only positions the Y axis, and has no locking device, and is easy to shift in the processing process, and the printing material is easy to be gouged by rigid contact.
