One locates spray code spraying apparatus automatically
Technical field
The present invention relates to a kind of spray code spraying apparatus, especially relate to one and automatically locate spray code spraying apparatus.
Background technology
Tire in the fabrication process, is extruding the tyre model or code name that need sign to use on work in-process, is beneficial to follow-up engineering use and the sign of finished product.
At present, each tire producer generally uses type wheel or the mode of manual coding. The mode of type wheel is used to have following shortcoming: (1) print word color is more shallow, please be unclear after sulfuration; (2) there is shape on crown layer surface, cannot print big word; (3) before sulfuration, print word is unclear, easily occurs tire base to enter wrong sulfuration mould; (4) when often kind of model is changed, need to changing print type matrix, employee adds load; (5) print word and easily change mistake (material also may by by mistake); (6) print type matrix and scraper are easily out of shape, and need to regularly change; (7) after printing word sulfuration, ghost image easily occurs. And the mode using manual coding has following shortcoming: input information errors easily occurs in (1); (2) mode is moved inconvenient, it is necessary to manually move; (3) differ in often kind of specification coordinate position, easily causes operation chaotic; (4) position fixing process needs manually to measure, and position accuracy is low.
Chinese patent CN203063278U discloses a kind of tire spray code spraying apparatus, this device comprises shower nozzle, support, controller, ink tank, voltage supply unit and agitating unit, shower nozzle is located on support, shower nozzle is connected with controller and ink tank respectively, voltage supply unit is connected with ink tank, and agitating unit stirs for ink tank provides; Special tire code-spraying printing ink is injected in ink tank, ink in ink tank is stirred by agitating unit, controller control voltage supply unit is ink tank pressurization, spray print content and spray grid printing formula are set by controller, support is adjusted to the height of needs, open the beginning button of controller, ink is printed on the tyre surface layer extruded by shower nozzle spray. This device belongs to manual coding mode, there is the shortcoming of above-mentioned manual coding mode.
Summary of the invention
The object of the present invention is exactly provide to overcome defect that above-mentioned prior art exists that a kind of structure is simple, print word is clear, can print big word, can adapt to the automatic location spray code spraying apparatus of various band coding product specification, coding accurate positioning, much slower labor intensity of operating staff fast.
The object of the present invention can be achieved through the following technical solutions:
One locates spray code spraying apparatus automatically, comprise frame, ink supply assembly and shower nozzle, also comprise control unit and shower nozzle moving assembly, described shower nozzle and shower nozzle moving assembly are connected with control unit respectively, described shower nozzle moving assembly comprises X-axis transmission rig and Y-axis transmission rig, described X-axis transmission rig is arranged in frame, and Y-axis transmission rig is arranged on X-axis transmission rig, and shower nozzle is arranged on Y-axis transmission rig.
