Description
Technical field
The present invention relates to a kind of pressure roller with roller shell, this roller shell is fixed in bearing disc, is rotatably installed on fixing bearing and can be vertically moves on bearing, and wherein roller shell can be under the tension by the take-up device that is linked to bearing disc.
Background technology
The fibre sheet that utilization will be dewatered, the if possible parallel suitable layers ground that is used for receiving water such as the felt that extrudes etc. drives the method between the pressure roller of pair roller and free driven running by rotation, use pressure roller commonly known in the art to combine the dehydration of the dehydration that is used for fibre material sheets, the particularly scraps of paper or paper pulp sheet with pair roller.In order to increase the effective area between pair roller and pressure roller and to improve dehydration, be provided with pressure shoes in the inside of roller shell, be pressed towards pair roller by means of the pressure shoes roller shell.Because pressure shoes acts on high pressure on roller shell, in the significant wearing and tearing of inner surface existence of roller shell, so in order to distribute the load of roller shell equably on whole length, roller shell axially is movably pressure shoes.
In the prior art, for example carry out this adjustment by compression spring and main shaft or by two hydraulic cylinders are set in roller shell inside.When main shaft is adjusted, by rotating main shaft in the pressure unit outside.When hydraulic cylinder is adjusted, require quite expensive control program, because hydraulic cylinder is a double action, and must accurately consider the different adjusting power that it causes based on the control system on different bottom surfaces and surface, piston tangent line limit.
Summary of the invention
The present invention is intended to arrange simply the adjusting of pressure roller roller shell.
Utilize a kind of pressure roller with roller shell to address this problem, this roller shell is fixed in bearing disc, is rotatably installed on fixing bearing and in axial direction removable on bearing, and wherein roller shell can be under the tension by the take-up device that is linked to bearing disc.Take-up device has: at least one compression spring, on one side it is supported on the bearing disc and another side is supported on the bearing; With at least one pressure medium cylinder, it is supported on another bearing disc and the bearing.
In the present invention, by by at least one, preferred a plurality of compression springs and at least one, preferred a plurality of pressure medium cylinder in conjunction with the pulling force and the adjusting that realize roller shell, wherein pressure medium cylinder makes compression spring be under the pulling force on the one hand, also realizes moving of roller shell on the other hand simultaneously.In this case, the position of roller shell can be measured very simply, for example by means of the displacement measurement system that belongs to hydraulic cylinder.Also can be by means of pressure-measuring system, the pressure of measurement in hydraulic cylinder or in the hydraulic system, because the rigidity curve of compression spring is known and is linear substantially, so can accurately be determined corresponding to the rigidity curve by the roller shell position of hydraulic cylinder.
The advantage that another one exists according to the present invention is, for example for changing roller shell, by the method to the pressure medium cylinder release pressure, release pressure very simply is because roller shell moves to predetermined resting position automatically by compression spring.
Description of drawings
Below with reference to accompanying drawing the preferred embodiments of the present invention are described.Fig. 1 is the axial cutaway view by the pressure roller according to the present invention, Fig. 2 is the cutaway view of II-II along the line by the pressure roller among Fig. 1, Fig. 3 is the cross-sectional view of Fig. 1 pressure roller of the pressure medium cylinder scope of magnification ratio, and Fig. 4 is the schematic diagram arranged according to the present invention corresponding to Fig. 1.
The specific embodiment
In Fig. 1, illustrate according to pressure roller of the present invention at axial section, this pressure roller comprises roller shell 1, fixing bearing 2 and pressure shoes 3.Pressure shoes 3 is fixed on the bearing 2.Roller shell 1 is pressed towards pressure shoes by unshowned pair roller.
By the same moved further of bearing disc 4 along double-head arrow 9, roller shell 1 can move with respect to pressure shoes 3, so by distributing corresponding load on the total length of roller shell 1 compressing of the pressure shoes on the roller shell 13, in this way, roller shell 1 inwardly and outwards moves continuously or off and on along double-head arrow 9.
For pressure roller functional requirement in accordance with regulations, roller shell 1 is being under the continuous tension on axial 10.In order to keep vertical tension, in order to realize moving of roller shell 1, be provided with the take-up device that constitutes by compression spring 11 and pressure medium cylinder 12 according to the present invention on the other hand on the one hand.Compression spring 11 and pressure medium cylinder 12 are fixed in bearing 2 on the one hand, are fixed in pressure rings 13 on the other hand, and wherein pressure rings 13 is supported in the interior ring 5 of bearing disc 4.Compression spring 11 is in the operation tension that the time is stressed.Pressure medium cylinder 12 is the single action pressure medium cylinder in its simple embodiment, and it is under pressure between bearing 2 and pressure rings 13 when operation equally.According to the stiffness curve of compression spring 11,, can move roller shell along the direction of double-head arrow 9 by improving or being reduced in pressure in the pressure medium cylinder 12.
By this very simple technology form of implementation of the present invention, also can be configured to regulate the control device of roller shell 1 very simply.For example, can connect pressure medium cylinder 12 and displacement measurement system 14, so can regulate the position of pressure medium cylinder 12 and the position of roller shell 1 simply.
Because always can guarantee the tension that roller shell 1 is enough by compression spring 11, do not need to be provided with extra control device, it can vertically obtain the pressure of roller shell 1.
As shown in Figures 1 and 2, in the illustrated embodiment, four compression springs 11 are with mutual 90 ° angle intervals setting.In addition, be provided with two hydraulic cylinders 12, they are positioned at the both sides of axis 10 mutually.Hydraulic cylinder is about 45 ° of settings of compression spring 11 skews.If the space that holds allows, hydraulic cylinder 12 and compression spring 11 be 10 1 row ground settings vertically certainly.
As seen, be provided with guider 15 in the lengthening of pressure medium cylinder 12 in Fig. 1 and among Fig. 3 of magnification ratio, it prevents the rotation of pressure rings 13 about bearing 2, rotates the buckling that causes compression spring 11 like this.
Schematic diagram according to arrangement of the present invention shown in Figure 4 wherein is provided with two compression springs 11 and two pressure medium cylinder 12 in this embodiment.Their inner support in hold-down support 2 and external support in the interior ring 5 of the bearing disc 4 of roller shell 1.By pressure medium cylinder 12, correspondingly roller shell 1 inwardly and outwards moves with respect to hold-down support 2 along the direction of double-head arrow 9.
