Abstract
The utility model provides a tipping paper press unreeling roll adaptsable to paper cores in variable sizes and solves the problems of failures of normally paper feeding and printing due to the fact that in limited quantities of rests, the conventional unreeling roll, even after inflation, fails to support the non-standard paper cores. The unreeling roll comprises an air swelling shaft (1) and a shaft sleeve. The shaft sleeve of a three-section form sleeves the air swelling shaft (1) and comprises a front connecting sleeve (2), a back connecting sleeve (3) and a variable-diameter sleeve (4) in the middle. The inner diameter of the shaft sleeve is moderately larger than the outer diameter of the air swelling shaft (1). Two ends of the variable-diameter sleeve (4) which is of a hollow cylinder form are fixedly connected with the front connecting sleeve (2) and the back connecting sleeve (3) respectively. Slot holes (7) are axially formed in the wall of the variable-diameter sleeve (4) and penetrate the same. The inner wall of the variable-diameter sleeve (4) is close to keys (8) of the air swelling shaft (1). Since elastic deformation of the middle section of the sleeve is achieved, the diameter of the variable-diameter sleeve (4) is expanded when the air swelling shaft (1) is inflated and returns to normal when the air swelling shaft (1) is deflated.
Description
Technical field
The utility model relates to printing equipment technical field, is specifically related to the unreeling shaft of printer.
Background technology
The unreeling shaft that tipping paper printer need to match with body paper refill size fixes body paper, in actual applications, the tipping paper body paper of existing batch application, its refill adopts standard specification conventionally, the folding and unfolding spool that corresponding printing unit is used is with it also the fixing main axis of dilatation of diameter dimension conventionally, and in large-scale standardized production, this form contributes to enhance productivity, the interchangeability of equipment component is high simultaneously, for the maintenance of unreeling shaft, changes more convenient.
But cannot avoid needing transposing to use the refill of different size, particularly when relating to new-product development, because can use some extraordinary tipping paper body paper, their refill is different from the standard specification of mass product, some refill diameters can substantially exceed standard specification, even if this still can not be by body paper stretching after will causing existing standard-sized unreeling shaft inflation, normally paper feed and printing, if change unreeling shaft for small lot test, R&D costs are too high, affect new product location, and at unreeling shaft repeatedly in Renewal process, be easy to cause the gas leakage of unreeling shaft valve inside, the problems such as accessory damage such as screw, and unreeling shaft because of itself weight heavier, change trouble, time-consuming.
In order to make tipping paper printer meet the requirement that small lot test is used, need to improve existing unreeling shaft, achieve the operating needs that can adapt to different coil diameter tipping paper body paper refills.
Some enterprises also develop the product that can realize above-mentioned purpose, for example " web unit unwinding shaft 201020260632.9 that diameter is adjustable ", the web unit unwinding shaft that diameter is adjustable, comprise that a small size unreels air-expanding shaft, the axial wall two ends that unreel air-expanding shaft in described small size arrange respectively a symmetrical reel diameter expansion body, described reel diameter expansion body consists of interior axle and the air bag with inflation inlet that is wrapped in interior axle outer wall, and described reel diameter expansion body forms fixing by the friction force after contacting between both inside and outside walls with small size spool diametrically; Axially by the lockhole that is separately positioned on the locking bolt of expanded in diameter body and be arranged on small size spool, locking.
Although this patent can not need to dismantle the conversion that unreeling shaft can directly be realized unreeling shaft diameter, to be suitable for the paper in reel of different size, reduce the time of changing unreeling shaft, reduce labour intensity, the faults such as valve inside gas leakage of avoiding appearance to cause due to replacing unreeling shaft, but it arranges by two ends outside main axis of dilatation the increase that independent air bag is realized unreeling shaft diameter, still continued the thinking of main axis of dilatation, and adopt this form of above-mentioned patent that new inflatable appliance need to be additionally provided, increased on the contrary the probability breaking down, for the main axis of dilatation that new deformation extent is larger is provided, its structure is more complicated, auxiliary facility increases, cost improves, topmost, the main axis of dilatation that its function is even as not larger in deformation extent.
