Abstract
The utility model relates to a combined type press roll of a granulation machine in the field of feed machinery. The combined type press roll comprises an eccentric shaft, wherein a press roll shell is arranged on the periphery of the eccentric shaft through a bearing, and the press roll shell comprises a rotating support shell and a wear-resisting shell. An inner layer of the rotating support shell is connected with the eccentric shaft in a rotating mode through the bearing, and the wear-resisting shell is fixedly sleeved on the periphery of the rotating support shell. Through adoption of the press roll structure, time for replacing the press roll can be obviously saved, replacement procedure is greatly simplified, and meanwhile material cost for replacing the press roll is also reduced.
Description
Technical field
The utility model relates to the feed manufacturing machine field, particularly a kind of ring die pelleter Combined press roller.
Background technology
Pressure roller is the core work parts of ring die pelleter, pressure roller shell, accentric support axle, bearing, seal etc., partly consists of.During work, the accentric support axle is fixed, and pressure roller shell rotation, and pressing materials, make it by nib, produce particle.Due to the pressure roller work under bad environment, working strength is large, and the pressure roller shell rate of wear is very fast, need frequently change.
In prior art, roller structure be pressure roller shell directly and bearing outer ring be connected, change pressure roller shell at every turn, must remove and again installation shaft hold and seal, waste time and energy; Dismounting has a strong impact on quality of fit and the service life of bearing and seal frequently in addition; The material cost of pressure roller shell integral replacing is higher.
The utility model content
The problem that the utility model exists for prior art; a kind of granulator Combined press roller is provided; be intended to make compression roller of granulator to change program simple, quick; that avoids frequent dismounting to connect pressure roller holds axle and seal; operation saves time, laborsaving, and the roller structure of split-type design can reduce the material cost of changing pressure roller.
The purpose of this utility model is to realize like this; a kind of granulator Combined press roller; comprise eccentric shaft; described eccentric shaft periphery is equipped with pressure roller shell by bearings, described pressure roller shell comprise the rotary support shell that internal layer is rotationally connected by described bearing and eccentric shaft and be fixedly set in rotary support shell periphery wear-resisting shell.
Adopt roller structure of the present utility model, the Combined press roll structure combined by rotary support shell and wear-resisting shell, during work, wear-resisting shell rotates together with the rotary support shell and pressing materials is realized the granulation function, when outer field wear-resisting shell is used wearing and tearing to need to change, only need change wear-resisting shell, and do not need to change whole pressure roller, do not need the attaching parts such as dismounting bearing and seal yet, can obviously save the time of changing pressure roller, and greatly simplify the replacing program, also reduce the material cost of changing pressure roller simultaneously.
For making accurately to locate between rotary support shell and wear-resisting shell, one end of the surfaces of revolution that described rotary support shell and wear-resisting shell are socketed mutually is provided with the conical surface that cooperatively interacts amplified to the end face direction, described pressure roller shell other end correspondence is provided with for the fixing tapering ring of rotary support shell and wear-resisting shell, described tapering ring be inlaid in rotary support shell and wear-resisting shell surfaces of revolution place and with wear-resisting shell cone match.
For rotary support shell and wear-resisting shell are reliably locked, the end on the face of cylinder that described tapering ring and rotary support shell are connected is provided with lock-screw, and described lock-screw hole is the half-thread hole be arranged on the rotary support housing.
The accompanying drawing explanation
The structure chart that Fig. 1 is granulator Combined press roller of the present utility model.
The enlarged drawing that Fig. 2 is I place in Fig. 1.
The A that Fig. 3 is Fig. 2 is to partial enlarged drawing.
Wherein, 1 locking nut; 2 seal receptacles; 3 oil sealings; 4 bearings; 5 rotary support shells; 6 eccentric shafts; 7 wear-resisting shells; 8 tapering rings; 9 lock-screws, 10 conical surfaces.
The specific embodiment
As Fig. 1, Fig. 2, Figure 3 shows that granulator Combined press roller of the present utility model, comprise eccentric shaft 6, eccentric shaft 6 peripheries support pressure roller shell are installed by bearing 4, pressure roller shell comprises the rotary support shell 5 that internal layer is rotationally connected by bearing 4 and eccentric shaft 6 and the wear-resisting shell 7 that is fixedly set in rotary support shell 5 peripheries, wherein, rotary support shell 5 two ends are supported and are arranged on eccentric shaft 6 by bearing 4 respectively, after installing oil sealing 3, bearing 4 outsides of one end are resisted against on the step of eccentric shaft 6 ends, it is fixing by the locking nut 1 that is fixed on eccentric shaft 6 ends that oil sealing 3 is installed by seal receptacle 2 in bearing 4 outsides of the other end, accurately fixing for making between rotary support shell 5 and wear-resisting shell 7, rotary support shell 5 is provided with an end of the surfaces of revolution that wear-resisting shell 7 is socketed mutually the conical surface cooperatively interacted 10 amplified to the end face direction, pressure roller shell other end correspondence is provided with for the fixing tapering ring 8 of rotary support shell 5 and wear-resisting shell 7, and tapering ring 8 be inlaid in rotary support shell 5 and wear-resisting shell 7 surfaces of revolution places and with wear-resisting shell 7 cone match, for rotary support shell 5 and wear-resisting shell 7 are reliably locked, tapering ring 8 is provided with lock-screw 9 with the end on the face of cylinder that rotary support shell 5 is connected, and as shown in Figure 3, the lock-screw hole is the half-thread hole be arranged on rotary support shell 4 bodies.
During work, wear-resisting shell 7 rotates together with rotary support shell 5 and pressing materials is realized the granulation function, when after wear-resisting shell 7 is used, wearing and tearing reach lifetime limitation, unclamp and exit lock-screw 9, exit tapering ring 8, can unload wear-resisting shell 7, after new wear-resisting shell 7 is installed, pack into successively tapering ring 8 and lock-screw 9 to locking state get final product.The utility model can obviously be saved the time of changing pressure roller, and greatly simplifies the replacing program, simultaneously, only needs to change outer field wear-resisting shell 7, and does not need to change whole pressure roller, greatly saves the material cost of changing pressure roller.
The utility model is not limited to above-described embodiment; every on the basis of the disclosed technical scheme of the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in the scope of the utility model protection.
