Abstract

The utility model relates to a disc positioning device for a movable grinding wheel of a grinding pulp machine. The utility model is composed of a shaft coupling, a pad, a movable grinding wheel, a screw bolt, a kick-out device, a positioning screw and a screen holder, wherein, the components are connected. A shoulder screw is arranged on the shaft coupler, and the shoulder screw is penetrated and connected with the screen holder and a via hole of the pad, and is positioned and matched with a concave hole of the movable grinding wheel. The kick-out device, the movable grinding wheel, the pad, the screen holder and the shaft coupling are assembled to integration by the screw bolt connecting with the shaft coupling. The utility model has simple disassembly and assembly, simple cleanness and simple structure, and can be reset correctly after the repeated disassembly and assembly.

Description

Positioning device for grinding pulp machine grinding wheel

The utility model belongs to the disc type mill machinery that is suitable for cereal in separation and the hybrid technology field specially, is the positioner of the moving emery wheel of a kind of disc type refiner particularly.

Usually mostly the connection location of the moving emery wheel of disc type refiner is that bolted by the break-through setting gauge is on screen holder, screen holder again by bolting on the shaft coupling that connects motor, make moving emery wheel grind oar and divide slag work with respect to quiet grinding wheel movement, but because the connection of moving emery wheel does not have positioner, so whenever the moving emery wheel of dismounting, after screen holders etc. clean and reinstall, often cause moving emery wheel, the screen holder displacement, cause moving emery wheel and quiet emery wheel contact area to change or cause the screen holder imbalance, the oar slag just to occur thick as not smoothing, it is low to go out the oar rate, directly the operate as normal of oar machine is ground in influence, and parts connect numerous and diverse, use comparatively inconvenience.

The purpose of the utility model provides a kind of connection positioner that grinds the motor-driven emery wheel of oar, to overcome the deficiency of existing machinery, makes its novel structure, and it is easy that dismounting is cleaned, and can repeat proper reset after the dismounting, guarantees that mill oar machine normally stably works.

The utility model is achieved in that with moving emery wheel back side system one shrinkage pool at the upper end of shaft coupling device one axial screw, the socket cap of axial screw is worn the positioning through hole that connects screen holder and pad and cooperated the location with the shrinkage pool of moving emery wheel; Moving emery wheel and pad, screen holder are set on the center projection of shaft coupling to wear by bolt and connect setting gauge and is connected shaft coupling and cooperates and fix, and consist of the connection positioner of the motor-driven emery wheel of defibrination.

The utility model adopts a bolt to cooperate shaft coupling will move emery wheel, pad, screen holder, setting gauge to be connected with shaft coupling and to be combined into one, and has installed axial screw and will move emery wheel, pad, screen holder connection and locate on shaft coupling.At work or work finish and need to clean or during maintenance, only need back out centre bolt, just detachably take off setting gauge, moving emery wheel and screen holder; When repeating to install after the cleaning, the locating hole that only will move emery wheel, screen holder cooperates the axial screw on the shaft coupling to be connected fastening again by centre bolt, guarantee to repeat the uniformity of dismounting, having solved be shifted unbalanced problem of moving emery wheel, screen holder that refitting causes effectively.The results showed, this apparatus structure novelty, easy to use, but can after repeated removal and assembling, need not proofread and correct proper reset, and screenings is thin, pulping rate can be carried more than 20%, has guaranteed that fiberizer normally stably works.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is the cutaway view of the utility model concrete structure.

The cutaway view of twin shaft position screw positioner in Fig. 2 the utility model.

As shown in drawings, the utility model comprises: shaft coupling (1), pad (2), moving emery wheel (3), bolt (4), setting gauge (5), axial screw (6) and screen holder (7).The middle axle center part of shaft coupling (1) is shaped on projection, is shaped on the axial screw that is connected with bolt (4) on the projection.Moving emery wheel (3) and pad (2), screen holder (7) are set on the projection of shaft coupling (1) and by bolt (4) company's of wearing setting gauge (5) and are connected with shaft coupling (1), with setting gauge (5), move emery wheel (3), pad (2) screen holder (7) and be connected with shaft coupling (1) and be combined into one.Device has axial screw (6) on the upper end of shaft coupling (1), is shaped on the positioning through hole that matches with axial screw (6) on screen holder (7) and the pad (2), is shaped on the location shrinkage pool on the moving emery wheel (3).The screw rod of axial screw (6) is connected and fixed on shaft coupling (1), socket cap is worn the company's screen holder (7) and the positioning through hole of pad (2) and the location shrinkage pool of moving emery wheel (3) and is connected.

For ease of dismounting, cleaning and the assembling of each parts of fiberizer, perhaps adopt twin shaft position screw location structure (see figure 2).This positioner design has two axial screws (6-1,6-2), and the location shrinkage pool that the screw rod of screw (6-1) is fixedly connected on shaft coupling (1), socket cap and the screen holder (7) is connected; The screw rod of axial screw (6-2) is fixedly connected on screen holder (7), socket cap wears the positioning through hole of company's pad (2) and the location shrinkage pool of moving emery wheel (3) is connected.

Claims

1, the positioner of the motor-driven emery wheel of a kind of defibrination, it comprises shaft coupling (1), pad (2), moving emery wheel (3), bolt (4), setting gauge (5) and screen holder (7), it is characterized in that this positioner also comprises axial screw (6), the screw rod of axial screw (6) is connected in shaft coupling (1), socket cap is worn and is connected screen holder (7) and the positioning through hole of pad (2) is connected with the location shrinkage pool on the moving emery wheel (3), moves on the center projection that emery wheel (3) and screen holder (7) and pad (2) be set in shaft coupling (1) and by bolt (4) company's of wearing setting gauge (5) and shaft coupling (1) to be connected and fixed.

2, positioner according to claim 1, it is characterized in that this device is equipped with two axial screws (6-1,6-2), the location shrinkage pool that the screw rod of axial screw (6-1) is fixedly connected on shaft coupling (1), socket cap and the screen holder (7) is connected, and the screw rod of axial screw (6-2) is fixedly connected on screen holder (7), socket cap wears the positioning through hole of company's pad (2) and the location shrinkage pool of moving emery wheel (3) is connected.
