Abstract
The invention relates to a roller, and particularly relates to a roller for circularly cooling a cooling liquid in the interior thereof. An internal-circulation cooling roll is provided, and comprises a roll shaft, and a roll sleeve covered outside the roll shaft, wherein a double-head spiral groove is circumferentially distributed on the roll shaft; the two heads of the double-head spiral groove are connected with the input hole and the output hole at one end of the roll shaft respectively; and the two tails of the double-head spiral groove are connected with each other at the other end of the roll shaft. The internal-circulation cooling roll provided by the invention is simple in structure, easy to manufacture and low in cost; and by the adoption of an annular groove for cooling, the roller is uniform in cooling, good in cooling effect and convenient to maintain.
Description
Technical field
The present invention relates to a kind of roll, especially a kind of cooling fluid is at the roll of roll inner loop cooling.
Background technology
At present, the method for existing cooling roll has interior cooling and outer cooling.Its China and foreign countries' cooling means generally is spraying cooling liquid around roll, and this mode is not suitable for requirement production environment drying, free of contamination situation.Internal cooling method generally is to have through hole at roll mandrel, and passes into cooling fluid, reaches the purpose of cooling by liquid circulation.Because through hole has certain distance apart from the roll mandrel circumference, so only can reduce near the through hole temperature, cooling effect is limited, and roll mandrel can be because uneven in temperature and be out of shape.
Summary of the invention
The technical problem to be solved in the present invention is: based on the problems referred to above, the invention provides a kind of interior circulating cooling roller even, good cooling results that cools off.
The technical solution adopted for the present invention to solve the technical problems is: a kind of interior circulating cooling roller is provided, comprise roll mandrel and be coated on the outer roller shell of roll mandrel, the twin-feed spiral groove is circumferentially arranged on the described roll mandrel, two heads of twin-feed spiral groove communicate with the input hole of this end and the delivery outlet of this end respectively at an end of roll mandrel, and two afterbodys of twin-feed spiral groove are connected with each other at the other end of roll mandrel.
End with input hole and delivery outlet of described roll mandrel is connected with to input hole and introduces cooling fluid and delivery outlet is drawn the swivel joint of cooling fluid.
The invention has the beneficial effects as follows: the present invention is simple in structure, easy to manufacture, cost is low; By the cannelure circulating cooling, cooling evenly, good cooling results, be convenient to maintenance.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing embodiment.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is along the expanded view of D among Fig. 1.
Among the figure: 1. roll mandrel, 2. axle sleeve, 3. twin-feed spiral groove, 4. input hole, 5. delivery outlet.
The specific embodiment
The invention will be further described in conjunction with specific embodiments now, and following examples are intended to illustrate the present invention rather than limitation of the invention further.
Interior circulating cooling roller shown in Fig. 1 or 2, comprise roll mandrel 1 and the roller shell 2 that is coated on outside the roll mandrel 1, twin-feed spiral groove 3 is circumferentially arranged on the roll mandrel 1, two heads of twin-feed spiral groove 3 communicate with the input hole 4 of this end and the delivery outlet 5 of this end respectively at an end of roll mandrel 1, and two afterbodys of twin-feed spiral groove 3 are connected with each other at the other end of roll mandrel 1.
End with input hole 4 and delivery outlet 5 of roll mandrel 1 is connected with to input hole 4 and introduces cooling fluids and delivery outlet 5 is drawn the swivel joint of cooling fluid.
During implementation, cooling fluid is incorporated into input hole 4 by swivel joint, then flows along twin-feed spiral groove 3, and cooling roll mandrel 1 is flowed out by delivery outlet 5 at last, and so roll mandrel 1 is cooled off in circulation.
Take above-mentioned foundation desirable embodiment of the present invention as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this invention technological thought, carry out various change and modification fully.The technical scope of this invention is not limited to the content on the specification, must determine its technical scope according to the claim scope.
