Insulating sleeve marking device for a kind of heater
Technical field
The utility model relates to printing equipment technical field, is specifically related to insulating sleeve marking device for a kind of heater.
Background technology
In the running of refrigerator, evaporator surface is easy to tie full frost, has reduced the refrigeration of refrigerator.In order to address this problem, conventionally adopt electric heater to carry out defrost.Its heater element is heating wire, coated one deck thermal insulation layer in heating wire outside, and sheathed insulating sleeve externally.Insulating sleeve is by extruder for shaping in process of production, then through cooling aftershaping.After moulding, need to stamp model and trade mark at sleeve surface, traditional method mainly adopts ink jet numbering machine to carry out coding, although this mode is simple, and spray printing also comparatively clear; But after sleeve pipe moulding is cooling in motion process easy sideslip, causing cannot spray printing.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of printing quality high, insulating sleeve marking device for heater simple in structure.
Technical problem to be solved in the utility model realizes by the following technical solutions:
Insulating sleeve marking device for a kind of heater, be arranged at sleeve pipe cooling device downstream, comprise column, the unlimited offset printing case in one upper surface is installed in described column upper end, in offset printing case, be provided with offset ink, in described offset printing case, being provided with rubber die rolls, in the middle of rolling, described rubber die is equipped with rotating shaft, described rotating shaft two ends are connected on the two side of offset printing case, on one sidewall of described offset printing case upper end, be provided with supporting frame, directly over rolling, described rubber die is provided with a pressure roller, described pressure roller is connected on supporting frame by bearing pin, described rubber die roll and pressure roller between be provided with sleeve channel.
Support frame as described above body is provided with kidney slot, and described bearing pin one end is connected in kidney slot, and can move along kidney slot.
It is that a metal rolls that described rubber die rolls, and at rubber die, rolls and on surface, is carved with printing type face.
Described pressure roller is a plastic roller, is provided with indent in the middle of this plastic roller.
The beneficial effects of the utility model are: the utility model rolls into row by rubber die and prints, and has changed traditional coding mode, make the word of printing more clear, there will not be the phenomenon of biting, and have improved operating efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, insulating sleeve marking device for a kind of heater, be arranged at sleeve pipe cooling device downstream, comprise column 1, the unlimited offset printing case 2 in one upper surface is installed in column 1 upper end, in offset printing case 2, be provided with offset ink, in offset printing case 2, be provided with rubber die and roll 3, rubber die is equipped with rotating shaft 4 in the middle of rolling 3, rotating shaft 4 two ends are connected on the two side of offset printing case 2, and can drive rotating shaft 4 rotations by transmission mechanism, on offset printing case 2 upper end one sidewalls, be provided with supporting frame 5, rubber die is provided with a pressure roller 6 directly over rolling 3, pressure roller 6 is connected on supporting frame 5 by bearing pin 7, rubber die roll 3 and pressure roller 6 between be provided with sleeve channel, sleeve pipe just in time can pass sleeve channel, supporting frame 5 is provided with kidney slot 8, bearing pin 7 one end are connected in kidney slot 8, and can move along kidney slot 8.It is that a metal rolls that rubber die rolls 3, at rubber die, rolls on 3 surfaces and is carved with printing type face, and pressure roller 6 is a plastic roller, in the middle of this plastic roller, is provided with indent, can make sleeve pipe there will not be deviation phenomenon.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
