Abstract
The present invention relates to a kind of chopping knife main shaft sealing construction, it is set with locking nut, platen, chopping knife component, cutter spindle sleeve, labyrinth platen, oil sealing axle sleeve, roller bearing, deep groove ball bearing successively in the front end of main shaft, fore bearing oil baffle disc and fore bearing disc, in labyrinth, platen and oil sealing axle sleeve overcoat dress front axle pressure cap, labyrinth platen are engaged with front axle pressure cap axially facing surface by triangle thread or saw-tooth thread.Even if triangle thread of the present invention or saw-tooth thread engagement system cause material flows into also easily to be thrown out of to come under the influence of centrifugal force, internal contamination axle is not detained in.
Description
Technical field
The invention belongs to food machinery field, is related to chopping knife, especially a kind of chopping knife main shaft sealing construction.
Background technology
The structure of prior art chopping knife main shaft seal as shown in Fig. 2 wherein labyrinth platen with front axle pressure cap in axial direction
Engaged by rectangular thread, for main shaft during rotation, material can radially contacting with along front axle pressure cap and labyrinth platen
Surface current enters, and is further continued for flowing into along front axle pressure cap and labyrinth platen axially facing surface, due to being engaged for rectangular thread, material
It is difficult to go out again along rectangular thread surface current after entering, is easily trapped in sealing structure.
The content of the invention
It is an object of the invention in place of overcome the deficiencies in the prior art, there is provided a kind of new cut for avoiding material from remaining is mixed
Knife main shaft sealing construction.
The technical proposal for solving the technical problem of the invention is：
A kind of chopping knife main shaft sealing construction, be set with successively in the front end of main shaft locking nut, platen, chopping knife component,
Cutter spindle sleeve, labyrinth platen, oil sealing axle sleeve, roller bearing, deep groove ball bearing, fore bearing oil baffle disc and fore bearing disc, are being confused
Palace platen and oil sealing axle sleeve overcoat dress front axle pressure cap, labyrinth platen pass through triangle thread with front axle pressure cap axially facing surface
Or saw-tooth thread engagement.
Moreover, making triangle on the platen of labyrinth or zigzag external screw thread is stupefied.
Moreover, triangle or zigzag internal thread groove are made on front axle pressure cap.
The advantages and positive effects of the present invention are：
Labyrinth platen of the present invention is engaged with front axle pressure cap axially facing surface by triangle thread or saw-tooth thread.Three
Angular screw thread or saw-tooth thread are due to for inclined-plane so that are also easily thrown out of under the influence of centrifugal force even if material flows into
Come, be not detained in internal contamination axle.
Brief description of the drawings
Fig. 1 is chopping knife main shaft sealing construction figure of the present invention；
Fig. 2 is prior art chopping knife main shaft sealing construction figure.
Embodiment
Below in conjunction with the accompanying drawings and the invention will be further described by specific embodiment, and following examples are descriptive
, it is not limited, it is impossible to which protection scope of the present invention is limited with this.
A kind of chopping knife main shaft sealing construction, it is set with locking nut 1, platen 2, chopping knife group successively in the front end of main shaft 12
Part 3, cutter spindle sleeve 4, labyrinth platen 5, oil sealing axle sleeve 7, roller bearing 8, deep groove ball bearing 9, fore bearing oil baffle disc 10 and fore bearing
Disc 11, platen and oil sealing axle sleeve overcoat dress front axle pressure cap 6 in labyrinth.
The innovative point of the present invention is：
Triangle or zigzag external screw thread are made on the platen of labyrinth, triangle or zigzag are made on front axle pressure cap
Internal thread, labyrinth platen are engaged with front axle pressure cap axially facing surface by triangle thread or saw-tooth thread.Triangle spiral shell
Line or saw-tooth thread are due to for inclined-plane so that are also easily thrown out of to come under the influence of centrifugal force even if material flows into, no
Internal contamination axle can be trapped in.
Above-described is only the preferred embodiment of the present invention, it is noted that for one of ordinary skill in the art
For, on the premise of inventive concept is not departed from, various modifications and improvements can be made, these belong to the protection of the present invention
Scope.
