Abstract
The utility model relates to an improved structure of a calender rubber roll, which comprises a hollow roller body, roll shafts installed at double ends of the roller body, an inner cylinder arranged in the roller body, an inlet pipe communicated with one end of the inner cylinder and a return pipe communicated with one end of the roll shaft, and is characterized in that an intermediate cylinder is provided between the roller body and the inner cylinder, and a cooling water chamber is formed between the intermediate cylinder and the roller body, and two ends of the intermediate cylinder are provided with a flange sleeved on the roll shaft, and the flange is provided with many cooling water through holes; and two ends of the internal cylinder are provided with cooling water through holes; and the position of the roll shaft corresponding to the inner cylinder cooling water through hole is provided with an osculum which is communicated with the inner cylinder cooling water through hole. The utility mode has the advantages that the space between the roller body and the inner cylinder is reduced, thereby the cooling water is near the work surface of the roller body, and guarantying uniform cooling of the calendering roller body working face with constant temperature, and improving cooling effect of the calendering roller body; in addition, the problems of film embossing effect and uneven film thickness caused by the small temperature difference between the inlet water and back water and unstable cooling are solved.
Description
Technical field
The utility model belongs to plastic sheeting manufacturing equipment technical field, particularly relates to a kind of improvement structure of calender rubber roll.
Background technology
As everyone knows, calender plays a part very important in the plastic sheeting manufacturing, belongs to the large-scale key equipment of film production.Wherein the stack of calender belongs to vitals, can the plastics of high temperature be rolled, and its working environment is under the hot conditions, and therefore, the roller working face of calender stack requires to carry out cooling processing at work.At present; The stack cooling processing generally is employed in feeding cooling water circulation way in the stack; Promptly in hollow roller, the inner core that can feed cooling water is set on axially; Have several hole for water sprayings on the said inner core barrel, send into cooling water through the water inlet pipe that is communicated with inner core, the hole for water spraying ejection cooling water of cooling water on the inner core barrel is in order to the cooling roller.Because the space between inner core and the roller is excessive, make that the cooling water of ejection can't be evenly near the roller inner surface, thereby be difficult to guarantee temperature constant, the lowering temperature uniform of roller working face, therefore can cause the film uneven distribution, influence film embossing effect.
Summary of the invention
The utility model provides a kind of simple in structure, improvement structure that can increase substantially the calender rubber roll of the stack cooling uniformity and cooling effect for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
The improvement structure of calender rubber roll; Comprise that hollow roll body, interference fit are installed in the roll shaft at roll body two ends, are arranged on inner core, water inlet pipe that is communicated with inner core one end in the roll body and the return pipe that is communicated with roll shaft one end; It is characterized in that: be provided with intermediate cylinder between said roll body and the inner core; Between intermediate cylinder and roll body, constitute cooling water cavity, said intermediate cylinder two ends are provided with the flange that is sleeved on the roll shaft, are shaped on a plurality of cooling water through holes on the said flange; Said inner core two ends all are shaped on the cooling water through hole, and the corresponding inner core cooling water of said roll shaft lead to the hole site place is shaped on the apopore that is communicated with it.
The utility model can also adopt following technical scheme:
Said inner core one end directly upwards is shaped on 4 cooling water through holes, and the other end directly upwards is shaped on 2 cooling water through holes.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme; Because this stack is provided with intermediate cylinder between roll body and inner core, and constitutes the cooling water cavity of circulation between intermediate cylinder and the roll body, dwindled the space between roll body and the inner core; Make the cooling water circulation more approach the roll body working face; Thereby guaranteed the cooling of stack body running face evenly, temperature constant has improved the cooling effect that rolls roll body.In addition; The design replaces the cooling water endless form of traditional double-decker stack, can make cooling water in cooling water cavity, fully roll body implemented cooling, and it is little to have solved the water inlet backwater temperature difference; Cooling is unstable, influences the problem of film embossing effect and uneven film thickness.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
Among the figure: 1, roll body; 2, intermediate cylinder; 3, flange; 3-1, cooling water through hole; 4, water inlet pipe; 5, return pipe; 6, inner core; 6-1, cooling water through hole; 7, roll shaft; 7-1, apopore; 8, cooling water cavity.
The specific embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1 and Fig. 2, the improvement structure of calender rubber roll comprises that hollow roll body 1, interference fit are installed in the roll shaft 7 at roll body two ends, are arranged on inner core 6, water inlet pipe 4 that is communicated with inner core one end in the roll body and the return pipe 5 that is communicated with roll shaft one end.Be provided with intermediate cylinder 2 between said roll body 1 and the inner core 6, between intermediate cylinder 2 and roll body 1, constitute cooling water cavity 8, said intermediate cylinder two ends are provided with the flange 3 that is sleeved on the roll shaft.Be shaped on a plurality of cooling water through hole 3-1 on said, in the present embodiment, be uniformly distributed with on the said flange and be shaped on 16 cooling water through hole 3-1.Said inner core two ends all are shaped on cooling water through hole 6-1, and in the present embodiment, said inner core one end directly upwards is shaped on 4 cooling water through holes, and the other end directly upwards is shaped on 2 cooling water through holes.Be shaped on the apopore 7-1 that is communicated with it in said roll shaft 7 corresponding inner core cooling water through hole 6-1 positions.
The operation principle of the utility model is:
Cooling water is passed through water inlet pipe; Flow in the inner core through flange, pass through the flange of the roll body other end again, 4 cooling water through holes that directly make progress through inner core one end; Cooling water is flowed in the cooling water cavity between roll body and the intermediate cylinder; Flow along the roll body wall then, enter into the interlayer between inner core and the water inlet pipe, through the return pipe that is communicated with roll shaft water is got back in the cooling water tank again through 2 cooling water through holes on the inner core other end.The calendering rubber roll of this three-decker makes cooling evenly, and cooling effect is fine.
