Abstract
The utility model discloses a locking device for a roll clearance fine adjuster of a pulverizer, which comprises a thin cylinder (1), a roll clearance fine adjustment screw (4), an adjusting support (5), a gland (6) and a fixing support (7). The thin cylinder (1) is fixed to the upper side of the adjusting support (5) with the gland (6), the roll clearance fine adjustment screw (4) is supported on the adjusting support (5), and the adjusting support (5) is disposed on the fixing support (7). The locking device is characterized in that a roll clearance fine adjustment braking block (2) is arranged at the front end of a piston rod of the thin cylinder (1), and a braking toothed wedge strap (3) is inlaid in the roll clearance fine adjustment braking block (2) and can be correspondingly meshed with a groove disposed on the roll clearance fine adjustment screw (4). The braking toothed wedge strap inlaid in the roll clearance fine adjustment braking block is pushed by the thin cylinder to be meshed with the groove on the roll clearance fine adjustment screw, and pneumatic type stepless locking for roll clearance fine adjustment of the pulverizer can be realized. In addition, the locking device for the roll clearance fine adjuster is simple in structure, convenient in operation and reliable in locking.
Description
Technical field
The utility model relates to a kind of locking device of roll clearance adjusting mechanism of powder manufacturing apparatus, especially a kind of flour mill roll clearance Fine adjustment knob locking device.
Background technology
Flour mill is most important powder manufacturing apparatus, general mainly be made up of six parts such as grinding roller, feeding mechanism, roll clearance adjusting mechanism, transmission mechanism, roll cleaning mechanism, discharge systems.Roll clearance adjusting mechanism is to be that roll clearance is regulated according to technological requirement to the distance between two roller surfaces on the two grinding roller lines of centres, makes the break release (flour extraction rate) of every pair of grinding roller of flour mill meet the requirements of index.The degree of tightness displacement of roll clearance and the two ends roll clearance of a pair of grinding roller are inconsistent, all will influence grinding effect.Therefore must design locking device on the roll clearance adjusting mechanism of flour mill, thereby the roll clearance that flour mill is adjusted remains unchanged when its operate as normal.
What flour mill roll clearance locking device adopted usually at present is traditional handwheel locking device, promptly on roll clearance fine setting screw rod, adds a screwed locking handwheel.Its advantage is simple in structure, and is easy to operate; But also have some shortcomings: 1. handwheel reliable lock property is relatively poor, because the flour mill in the work is in vibrational state always, under the double action of self gravitation and flour mill vibration, thereby the handle handwheel is easy to generate loosening the rotation roll clearance locking is lost efficacy; 2. connection reliability is relatively poor between handwheel and the handle, because be to be threaded between handwheel and the handle, under effects such as vibration, is easy to generate loosening.Also there is partial devices to adopt the air pressure retaining mechanism in addition; Like patent No. ZL 200920031966.6; Name is called the patent of flour mill roll clearance adjuster locking device, and 3 grooves are arranged on its roll clearance adjusting screw(rod), and the cylinder piston rod termination puts in groove can realize locking; Shortcoming is that termination and groove must correspondence put in place, can not realize stepless locking.
Summary of the invention
The utility model provides a kind of both convenient, simple to the locking operation of flour mill roll clearance fine setting screw rod, again the pneumatic type flour mill roll clearance Fine adjustment knob locking device of reliable lock to the defective and the drawback of existing flour mill roll clearance adjusting mechanism locking device.
The utility model solves the technical scheme that its technical problem adopted:
This flour mill roll clearance Fine adjustment knob locking device comprises slim cylinder (1), roll clearance fine setting screw rod (4), regulates bearing (5), gland (6) and hold-down support (7); Said slim cylinder (1) is fixed in adjusting bearing (5) top that is provided with gland (6), and roll clearance fine setting screw rod (4) is bearing in to be regulated on the bearing (5), regulates bearing (5) and places on the hold-down support (7).Be characterized in: the piston rod front end of said slim cylinder (1) is provided with roll clearance fine setting brake block (2); On roll clearance fine setting brake block (2), be embedded with braking toothed wedge belt (3), braking toothed wedge belt (3) can be finely tuned the set corresponding tabling of groove of screw rod (4) with roll clearance.
In the such scheme, said braking toothed wedge belt (3) can be finely tuned the corresponding tabling of groove of the similar belt wheel that screw rod (4) adopted with roll clearance.
Said rolling transfers fine setting screw rod (4) by placing the thrust ball bearing supporting of regulating on the bearing (5).
Said slim cylinder (1) piston rod axis and roll clearance fine setting screw rod (4) axis normal.
The beneficial effect of the utility model is: promote the groove tabling on embedded braking toothed wedge belt of roll clearance fine setting brake block and the roll clearance fine setting screw rod through slim cylinder, realize the stepless locking of pneumatic type of flour mill roll clearance fine setting.Simple, easy to operate, the reliable lock of this flour mill roll clearance Fine adjustment knob locking device structure.
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Description of drawings
Accompanying drawing 1 is the structural representation of flour mill roll clearance Fine adjustment knob locking device.
The specific embodiment
This flour mill roll clearance Fine adjustment knob locking device structure is as shown in the figure.It comprises slim cylinder 1, roll clearance fine setting brake block 2, braking toothed wedge belt 3, roll clearance fine setting screw rod 4, regulates bearing 5, gland 6 and hold-down support 7.Slim cylinder 1 is installed in locking device and regulates bearing 5 tops; Regulating bearing 5 is fixed on the hold-down support 7; Regulate bearing 5 and be provided with gland 6, roll clearance fine setting brake block 2 places the piston rod front end of slim cylinder 1, and braking toothed wedge belt 3 is embedded on the roll clearance fine setting brake block 2; Roll clearance fine setting screw rod 4 is installed in to be regulated on the bearing 5, by placing the thrust ball bearing supporting of regulating on the bearing 5.The tooth wedge of braking on the toothed wedge belt 3 can to finely tune the groove of the similar belt wheel that screw rod 4 adopted corresponding chimeric with roll clearance.The axis normal of the axis of slim cylinder 1 piston rod and roll clearance fine setting screw rod 4.
During this device work, at first the roll clearance of coarse adjustment flour mill is finely tuned the flour mill roll clearance through the roll clearance trimming hand wheel then.When the flour mill roll clearance is adjusted when satisfying technological requirement; Press the locking button on the control panel; At this moment, the control gas in the source of the gas drives slim cylinder 1 work through the atmospheric control of flour mill, and the piston rod of slim cylinder 1 promotes 2 motions of roll clearance fine setting brake block; Make braking toothed wedge belt 3 compress the groove on the roll clearance fine setting screw rod 4, make the stepless locking of its mutual chimeric realization.
