Abstract

The utility model relates to a stop block of a spline housing used on a screw extruder, and the stop block comprises a screw, an output shaft and the spline housing. The utility model is characterized in that the stop block is arranged on a screw tail being 1 to 15 mm apart from one end of the spline housing and the output shaft of a gear case; the stop block can be one or a plurality of incontinuous welding spots welded by a welding rod, and also can be fixed on the screw tail and the output shaft of the gear case through a metal block. The spline housing (5) can be blocked by the stop block when slipping to the welding spots (5) without slipping out a groove. When the screw needs to be disassembled during the production process, the screw provided with an antiskid is only drawn out from the other end of the screw that connected with the spline housing, and the end of the screw that is provided with the antiskid is only led into the spline housing along the groove of the spline housing when resetting. The structure of the stop block is very simple, in addition, the utility model is convenient and practical, and effectively solves the equipment damage accident caused by the gression of the spline housing.

Description

The stopping means of screw extruder upper spline cover
Technical field
The utility model relates to a kind of stopping means of screw extruder upper spline cover, especially adapts to double screw extruder and multi-screw extruder, belongs to the screw extrusion machinery accessory device.
Background technology
Screw extruder is field of high polymer material processing a kind of equipment commonly used, in polymer blended material of preparation and reactive processing, has widely and uses, especially double screw extruder.
At present, industrial double screw extruder commonly used provides power by gear-box for the rotation of screw rod, and the afterbody of twin-screw is connected with two output shaft front ends of gear-box by spline housing.
The afterbody of twin-screw and output shaft front end are cylindric, and the surface evenly, be furnished with the groove with screw rod or output shaft central axes, and corresponding with it groove is arranged also in the spline housing, before producing spline housing is enclosed within along groove on the afterbody groove and gearbox output shaft front end groove of twin-screw, spline housing can slide before and after groove.
If single spline housing skids off from gearbox output shaft or spline housing tail end in producing, the screw rod that this spline housing connects can stop operating because losing the power drive of gearbox output shaft, the screw rod that another root is rotated further can bump or interlock with the screw rod that this root does not rotate, cause screw rod, gear-box to turn round bad substantial equipment damage accident, once damage to spend units up to ten thousand.In order to prevent that this type of accident from taking place, existing with jackscrew spline housing being fixed on twin-screw and the output shaft before the production of being everlasting on the extruder.
With jackscrew fixedly spline housing though certain effect is arranged, have following shortcoming: to change screw rod when one, changing the line of production, again extract screw rod after all will taking the jackscrew on the spline housing apart at every turn, unusual trouble, frequent dismounting also can cause jackscrew easily sliding or come loose; Two, time of changing the line of production short, fully occupied, the Manufacturing Worker often forgets jackscrew is screwed on, and causes spline housing to slip off; Three, the vibrations that always do not stop aborning of the twin-screw that connects of spline housing and gearbox output shaft are easy to be shaken pine by being threaded in jackscrew on twin-screw and the gearbox output shaft, shake falls under long-term vibration.These phenomenons all can cause spline housing to skid off, and cause screw rod, gear-box to turn round bad substantial equipment damage accident.
The utility model content
The purpose of this utility model: the stopping means that aims to provide a kind of screw extruder upper spline cover, by the anti-slip mode of a kind of spline housing of novelty, overcoming existing jackscrew technique for fixing easily shakes pine, shakes, to change the deficiency of screw rod when changing the line of production, prevent that effectively spline housing from skidding off, both prevent device damage, and can improve the level of production again, reduced economic attrition.
The stopping means of this screw extruder upper spline cover is made up of screw rod, output shaft, spline housing, it is characterized in that: at a device of limiting on the screw rod tail at spline housing one end 1~15mm place and the gearbox output shaft respectively.
Described stopping means can be one and a plurality of discontinuous solder joint with the welding rod welding, or is fixed on the metal backup on screw rod tail, the gearbox output shaft.
The stopping means that this screw extruder upper spline that proposes according to above technical scheme overlaps, advantage is very remarkable, and apparatus structure is simple, the screw rod convenient disassembly, improve production efficiency, effectively solved the device damage accident that causes because of the spline housing positioning, reduced equipment loss.
Description of drawings
Fig. 1: the utility model structural representation.
Among the figure: 1, screw rod 2, output shaft 3, spline housing 4, groove 5, solder joint
The specific embodiment
The stopping means of this screw extruder upper spline cover, form by screw rod, output shaft, spline housing, it is characterized in that: at a device of limiting on the screw rod tail at spline housing one end 1~15mm place and the gearbox output shaft respectively, this stopping means can be one and a plurality of discontinuous solder joint with the welding rod welding, also can be fixed on screw rod tail and the gearbox output shaft with metal derby.When spline housing 3 slides into solder joint 5 places, can block by limited device, and can not skid off groove.When needing dismantling screw in the production process,, the screw rod that will be provided with shoe gets final product as long as from connecting the other end extraction of spline housing, just will having an end of shoe to send into spline housing along the groove of spline housing during refitting.Apparatus structure is very simple, and convenient and practical, has solved the device damage accident that causes because of the spline housing positioning effectively.
The principle of this stopping means is to destroy originally level and smooth groove, make when spline housing slides into herein destroyed because of groove, can not be by herein, thus reach spacing anti-skidding purpose.
