Abstract
The utility model discloses a chill roll connection structure for gravure press, including the chill roll that is equipped with the inner chamber, the one end protrusion of chill roll forms the business turn over water end (W. E. ), it has the end cover of fixing in wallboard one side to peg graft earlier on the business turn over water end (W. E. ), and rethread bearing activity is later pegged graft on the wallboard, the axial tip of business turn over water end (W. E. ) is equipped with and is equipped with the delivery port on water inlet, the cylinder terminal surface, lead to the inlet tube that has the butt joint water inlet and take the hole for water spraying in the chill roll inner chamber, terminal axle is installed to the other end of chill roll, terminal epaxial really up to the mark cooperation is connected with and is used for supporting chill roll pivoted copper sheathing jointly with the bearing. The utility model is suitable for a gravure press's chill roll can effectively be avoided because the chill roll is high -speed rotatory or when using for a long time, phenomenon that the terminal axle of chill roll leads to not changeing because the bearing card is died to and the dry grinding phenomenon, greatly reduced the plant maintenance cost, showing and improving printing efficiency.
Description
Technical field
This utility model relates to printing machinery technical field, particularly relates to a kind of intaglio press chill roll attachment structure.
Background technology
Chill roll is the important composition parts of unit type intaglio press, and its effect is that the material film after drying through drying baker with high surfaces temperature is cooled down, and reduces the deformation that material film is heated, and chill roll is with material film high speed rotating.In prior art, the terminal shaft of chill roll uses bearing to connect, and in high-speed rotation, bearing generates heat hot due to rolling friction, cause that two problems easily occur: 1, bearing mainly adopts ferrous materials to prepare, and is therefore very easy to occur that card stubbornly refuses to turn phenomenon；2, Bearing inner needs interpolation lubricant to play lubrication, but due to heating functioin, is very easy to situation dry grinding occur when supplemental lubrication agent not in time.
In sum, the bearing of chill roll terminal shaft connects and is easily caused fault, so that often safeguard so that cost increases, efficiency reduces, so being highly desirable to the chill roll attachment structure of a kind of not easily stuck, failure rate is low of design.
Utility model content
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of intaglio press chill roll attachment structure is provided, the terminal shaft of chill roll connects not in use by bearing, can be prevented effectively from and produce the phenomenon generation that card stubbornly refuses to turn due to chill roll high speed rotating or life-time service, considerably reduce cost of equipment maintenance, and significantly improve printing efficiency.
The technical scheme in the invention for solving the above technical problem is: a kind of intaglio press chill roll attachment structure, including the chill roll being provided with inner chamber, one end of described chill roll is protruded and is formed turnover water end (W.E.), described turnover water end (W.E.) is first plugged with the end cap being fixed on wallboard side, it is plugged on wallboard again through bearing activity afterwards, the axial end portion of described turnover water end (W.E.) is provided with water inlet, cylinder end face is provided with outlet, described chill roll inner chamber is connected with docking water inlet the water inlet pipe with hole for water spraying, the other end of described chill roll is provided with terminal shaft, the copper sheathing being connected with for rotating with bearing common support chill roll really up to the mark on described terminal shaft.
Preferably, the material of described copper sheathing is tin-phosphor bronze.
Preferably, the material model of described copper sheathing material tin-phosphor bronze is ZCuSn10P1.
Compared with prior art, the beneficial effects of the utility model: mainly for the chill roll of intaglio press, solve printer when running up, the terminal shaft of chill roll is stuck and cause the problem not turned due to bearing, this utility model adopts copper sheathing, thus constituting axle sleeve annexation with terminal shaft, machine is in operation process, chill roll is subject to material layer tension and rotates, then copper sheathing also and then rotates to reach the purpose of operating, when then reaching machine at high speeds operating or life-time service, the copper sheathing of chill roll end is all without stuck effect occur, and without using any lubricant, avoid dry grinding phenomenon.
Accompanying drawing explanation
Fig. 1 is the front schematic view of this utility model preferred embodiment.
Fig. 2 is the side right view of this utility model preferred embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, this utility model is described further.In preferred embodiment cited as " on ", D score, "left", "right", the term such as " centre " and " ", only understanding for ease of narration, and it is not used to limit the enforceable scope of this utility model, the change of its relativeness or adjustment, changing under technology contents without essence, when being also considered as the enforceable category of this utility model.
Refer to Fig. 1 and Fig. 2, a kind of intaglio press chill roll attachment structure of this utility model preferred embodiment design, including chill roll 1, bearing 5, copper sheathing 7 and terminal shaft 6, one end of chill roll 1 is fixed in wallboard 8 by bearing 5, the other end of chill roll 1 installs terminal shaft 6, the copper sheathing 7 that is connected really up to the mark on terminal shaft 6, both constitute axle sleeve attachment structure, the centrage of copper sheathing 7 and bearing 5 central shaft by chill roll 1.This utility model retains conventional mounting mode, and bearing is changed into copper sheathing, simple in construction, runs up stable, failure rate is low.
Chill roll 1 is the cylindrical structural being provided with inner chamber, protrude in its one end and form cylinder turnover water end (W.E.) 11, the turnover water end (W.E.) 11 of chill roll 1 is sequentially connected with end cap 9 and bearing 5, end cap 9 is fixed on the side of wallboard 8 by 4 screws, bearing 5 is annular, being made up of inner ring, outer ring, retainer and ball, the outer ring of its middle (center) bearing 5 is inserted admittedly in wallboard 8, inner ring is fixedly sleeved on turnover water end (W.E.) 11, and bearing 5 is in order to support chill roll 1.The axial end portion of turnover water end (W.E.) 11 offers and offers radially outlet 3 on water inlet 2, cylinder end face, is connected with the water inlet pipe 4 with hole for water spraying in the inner chamber of chill roll 1, and water inlet pipe 4 docks water inlet 2.During machine operation, water inlet 2 water added or coolant, it is sprayed onto the inner surface of chill roll by the hole for water spraying of water inlet pipe 4, is then flowed out by outlet 3, it is achieved coolant circulates, synergism reduces the temperature on chill roll surface.
Copper sheathing 7 of the present utility model is the copper alloy annulated column that cross section is annular, and its external diameter is 28mm, internal diameter is 4.28mm, and internal diameter matches with the external diameter of the terminal shaft 6 of chill roll, copper sheathing 7 for and bearing 5 common support chill roll 1 realize chill roll and rotate.What copper sheathing 7 of the present utility model preferably employed is tin-phosphor bronze material, and such as ZCuSn10P1 material model, hardness and abrasion resistance are all significantly high, it is adaptable to heavy load, at high speed, use under high-temperature and strong friction.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent replacement and improvement etc. made within spirit of the present utility model and principle, should be included within protection domain of the present utility model.
