Abstract
The utility model relates to a sealing element, in particular to a sealing element used for a press roll assembly of a pelletizer. The utility model adopts the technical scheme as follows: the sealing element used for the press roll assembly of the pelletizer comprises a sealing element body and a central hole (7), the sealing element body is formed by an outer body and an inner body A (3) which comprises a circular ring-shaped boss A (2) protruding to the left side, the central hole (7) is formed in the middle of the sealing element body, a mounting hole (8) is formed between the outer body and the inner body A (3), and a first circular ring-shaped boss (4), a second circular ring-shaped boss (5) and a third circular ring-shaped boss (6) are arranged on the right side of the inner body A (3). With the technical scheme, the utility model has the following benefits: the right side of the inner body A (3) of the sealing element is a curved surface, so that the sealing effect is improved.
Description
Technical field
The utility model relates to a kind of seal, and particularly a kind of granulator pressure roller assembly is used seal.The utility model belongs to mechanical equipment technical field.
Background technology
The operation principle of ring die pelleter is to utilize the strong squeezing action of ring mould and pressure roller; With living beings clamp-on gradually the ring mould nib in and in nib, be shaped; Because living beings continuously extruded between the mould roller; Material after the shaping constantly is column from nib discharges, and is cut into the particle of Len req then by cutting knife.
Ring die pelleter mainly is made up of motor, the empty axle of transmission, pressing mold and pressure roller.For the ring die pelleter of belt pulley transmission, motor drives the empty axle rotation of transmission through belt pulley, and the empty axle of transmission drives pressing mold again or/and the pressure roller rotation.For gear-driven ring die pelleter, motor is through the empty axle rotation of gear driven transmission, and the empty axle of transmission drives pressing mold again or/and the pressure roller rotation.
Existing granulator pressure roller assembly is as shown in Figure 2 with seal; It comprises seal body and centre bore 7; Seal body is protruded to the left and is become the endosome 10 of circular boss A2 to constitute with containing by containing the ectosome that protrudes to the right and become circular boss B9, and the centre of seal body is a centre bore 7.It is mainly not enough: because the right side of seal endosome 10 is planes, sealing effectiveness is poor.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes prior art, provides a kind of granulator pressure roller assembly of good sealing effect to use seal.
For realizing above-mentioned purpose; The utility model adopts following technical scheme: a kind of granulator pressure roller assembly is used seal; It comprises seal body and centre bore, and seal body is protruded to the left and become the endosome A of circular boss A to constitute with containing by ectosome, and the centre of seal body is a centre bore; Also be provided with installing hole between said ectosome and the endosome A, the right side of said endosome A is provided with the first circular boss, the second circular boss and the 3rd circular boss.
Further, the protrusion height of the said first circular boss>protrusion height of the said second circular boss, the protrusion height of the protrusion height of the said second circular boss=said the 3rd circular boss.
Further, said ectosome is to contain the ectosome that protrudes to the right and become the conial ring shape boss.
Owing to adopt technique scheme, the utlity model has following beneficial effect:
1, three layers of boss make the right side of seal endosome A become curved surface, form the labyrinth sealing road, have improved the sealing effectiveness of seal, and sealing is reliable, and airtight quality is good.
2, the protrusion height of the first circular boss>protrusion height of the second circular boss, the protrusion height of the protrusion height of the second circular boss=the 3rd circular boss further facilitates processing, improves the sealing effectiveness of seal.
3, adopt the conial ring shape boss, make things convenient for seal to be installed into granulator pressure roller assembly, convenient use, maintenance.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the pressing mold cover structure sketch map of prior art.
Among the figure: 1, conial ring shape boss, 2, circular boss A, 3, endosome A, 4, the first circular boss, 5, the second circular boss, the 6, the 3rd circular boss, 7, centre bore, 8, installing hole, 9, circular boss B, 10, endosome B.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Embodiment
As shown in Figure 1; A kind of granulator pressure roller assembly is used seal; It comprises seal body and centre bore 7, and seal body is protruded to the left and become the endosome A3 of circular boss A2 to constitute with containing by containing the ectosome that protrudes to the right and become conial ring shape boss 1, and the centre of seal body is a centre bore 7; Also be provided with installing hole 8 between ectosome and the endosome A3, the right side of endosome A3 is provided with first circular boss 4, second circular boss 5 and the 3rd circular boss 6.
Wherein: the protrusion height of the first circular boss 4>protrusion height of the second circular boss 5, the protrusion height of the circular boss 6 of the protrusion height of the second circular boss 5=3rd.
Owing to adopt three layers of boss, and the protrusion height of the first circular boss>protrusion height of the second circular boss, the protrusion height of the protrusion height of the second circular boss=the 3rd circular boss; Make the right side of seal endosome A become curved surface, and near centre bore, curved surface rise and fall little; Away from centre bore; Curved surface rises and falls big, progressively improves the sealing effectiveness away from the seal of central hole, improves the sealing effectiveness of whole seal.
Adopt the conial ring shape boss, make things convenient for seal to be installed into granulator pressure roller assembly, convenient use, maintenance.
The utility model is not limited to the foregoing description, and all employings are equal to technical scheme that replacement or equivalence replacement form and also all belong to the utility model and require the scope protected.
