2. be embedded Teflon block further in the body as the locating platform directly contacted with smalt, thus conventional rigid location structure can be avoided in printing process to the scuffing that smalt causes, be conducive to improving quality and reducing costs, such as the scuffing ratio of traditional bakelite location structure to smalt is higher, is about 10%.
3.for conventional square justifying smalt; Design Orientation groove squarely; and corner has the relief portion can avoiding smalt corner respectively; then can adapt to glass profile, size thus good Locating Glass; the corner of smalt can also be protected, especially avoid smalt and can prevent from scraping glass powder thus causing scuffing to glass body conversely.
4.arranging bottom detent negative pressure locating hole be quadrate array arrangement, and every row negative pressure locating hole quantity>=5, can better, more stable location large scale justifying glass.
5.the auxiliary tank of connection is set in the relative both sides of detent, conveniently picks and places smalt in detent, be also convenient for changing Teflon block.
6.the Opening length that auxiliary tank is communicated with the Opening length in detent direction and the vertical direction in described direction is proportional with detent respective direction Opening length respectively, and be conducive to finger and stretch into, more comfortable operates smalt.
7.the respective sides arranging Teflon block has the lug stretching into corresponding auxiliary tank, then can make the better screens in a substrate of Teflon block on the one hand, on the other hand because Teflon block easily expands with heat and contract with cold, lug extends in auxiliary tank has certain extension space, and Teflon block can be avoided to be completely restricted the situation of the distortion thus easy heat expansion arches upward in closed pockets.
8.at least both sides cell wall arranging detent has arc location division, and in corresponding side by the position of arc location division restriction smalt, thus the contact area of detent cell wall and smalt can be reduced, reduce the possibility to smalt wearing and tearing.
9.smalt location of the present utility model, printing assembly, except smalt printing apparatus of the present utility model, also relate to supporting half tone, and design half tone has the printing element of array arrangement, once can complete the printing of justifying smalt, greatly improve printing efficiency.Especially the half tone designed meets: when in the Printing Department and body of half tone during detent contraposition, the symmetrical centre of any adjacent four printing elements all around on the corresponding half tone of negative pressure locating hole, then the location of smalt and printing cooperatively interact the best, and printing quality is high.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
Embodiment 1
As shown in Figure 1-2, a kind of smalt printing apparatus, comprise the plate-like body 2 for supporting smalt, body 2 has a detent 24, can hold and locate the square smalt of a justifying, and the bottom 242 of detent 24 offers array arrangement, multiple negative pressure locating holes 262 that can act on the whole bottom surface being contained in smalt in detent 24.
Concrete, body 2 comprises substrate 22, is specially bakelite plate, and the middle part of substrate 22 is offered caulking groove and is embedded a Teflon block 26.The end face of Teflon block 26 lower than substrate 22 end face, thus forms detent 24, and the shape of detent 24 and smalt form fit are square, and the end face of Teflon block 26 is as the bottom 242 of detent 24.Also namely negative pressure locating hole 262 is arranged on Teflon block 26 for adsorbing location smalt.More specifically, substrate 22 thickness is at 15mm, and Teflon block 26 to sink e:0.27mm relative to substrate 22.Negative pressure locating hole 262 is arrangement in quadrate array, no matter is longitudinal or horizontal, often arranges negative pressure locating hole 262 quantity and be 5.
The corner of detent 24 is respectively to the relief portion 264 of the arcuation be recessed to form outward for avoiding being contained in corresponding one jiao of smalt in detent 24.Make detent 24 can adapt to glass profile, size thus good Locating Glass, the corner of smalt can also be protected, especially avoid smalt and can prevent from scraping glass powder thus conversely scuffing be caused to glass body 2.In addition, relief portion 264 can be the through hole of through body 2 thickness direction, is also conducive to draining during cleaning tool.
On body 2, the relative both sides of detent 24 also namely substrate 22 be provided with the auxiliary tank 222 being communicated with detent 24.The Opening length a that auxiliary tank 222 is communicated with detent 24 direction be the 0.3-0.5 of detent 24 respective direction Opening length c doubly, the Opening length b that auxiliary tank 222 is communicated with the vertical direction in detent 24 direction is that also namely the 0.5-0.6 of c is doubly for detent 24 respective direction Opening length.Concrete, in the present embodiment, c is 37.5mm, a be 14.75mm, b is 20mm.Auxiliary tank 222 to sink f:10mm relative to substrate 22.
In addition, the respective sides of Teflon block 26 extends certain distance respectively in the auxiliary tank 222 of correspondence, forms lug 266.Concrete, in the present embodiment, the distance d that lug 266 extends is 1.75mm.Arranging of lug 266 can make Teflon block 26 better screens in substrate 22 on the one hand, on the other hand because Teflon block 26 easily expands with heat and contract with cold, lug 266 extends in auxiliary tank 222 has certain extension space, and Teflon block 26 can be avoided to be completely restricted the situation of the distortion thus easy heat expansion arches upward in closed pockets.
During use, the end face platform that directly smalt of justifying can be placed on Teflon block 26 positions, location is specifically by realizing the general negative pressure device in the external this area of negative pressure locating hole 262.
Embodiment 2
As Figure 2-3, a kind of smalt printing apparatus, is with the difference of embodiment 1: the both sides cell wall of detent 24 curves inwardly and is formed with arc location division 244, and limits the position of smalt in corresponding side by arc location division 244.Thus the contact area of detent 24 cell wall and smalt can be reduced, reduce the possibility to smalt wearing and tearing.Especially arc location division 244 is arranged on the side of auxiliary tank 222, quantity >=2, arc location division 244 effect of corresponding side is better simultaneously.
Embodiment 3
As shown in Fig. 1-2,4-5, smalt location, printing assembly, it smalt printing apparatus comprising embodiment 1 and the half tone 4 coordinating this smalt printing apparatus to use, half tone 4 comprises flaky matrix 42 and matrix 42 has the square Printing Department 6 that shape, size and smalt adapt, and Printing Department 6 comprises the printing element 62 of array arrangement.
Concrete, the arrangement of printing element 62, with the Printing Department 6 of half tone 4 with on body 2 during detent 24 contraposition, on the corresponding half tone of negative pressure locating hole 262 4, the symmetrical centre O of corresponding adjacent four printing elements 62 is all around as the criterion.Then the location of smalt and printing cooperatively interact the best, and printing quality is high.
During use, as described in example 1 above the smalt of justifying is positioned on the Teflon block 26 of printing apparatus, in detent 24, afterwards half tone 4 is covered on smalt, Printing Department 6 is corresponding with the district to be printed of smalt, being applied to by printing-ink on half tone 4 reprints on smalt by each printing element 62 pattern again, finally justifying smalt is cut, namely obtain 36 pieces of monolithic glass, and each is all completed for printing.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
