Description

The Pneumatic drum polishing roll

The utility model belongs to a kind of corollary equipment, is mainly used in the surface finish of wood furniture and various items.

The equipment that the surface finish of various items is adopted usually is polishing roll, and its structure is at axis peripheral hardware polishing roll dish, and the polishing roll dish can require to be divided into husky roller and cloth rewinder roll etc. according to performance and the fineness of object.This traditional polishing roll, roller is admittedly straight, and hardboard can only polish body surface is smooth, can not be to the object polishing of out-of-flatness surface.For example, bending-wood spare furniture is polished, just can not use this traditional polishing roll, often adopt manual polishing, but that effect is compared in this manual polishing and the polishing of high speed polishing roller is relatively poor, speed is also slow, can not adapt to need of production.Traditional polishing roll on the other hand, the fixing also trouble comparatively of polishing roll dish and axis, both can not fixing compact, affect polishing effect, and the polishing roll dish is thick to sink the cost height.

The purpose of this utility model provides a kind of Pneumatic drum polishing roller, can effectively carry out high speed polishing to out-of-flatness surface object or crooked object surface.Make simultaneously the polishing roll dish frivolous easily fixing low with cost.

The utility model is by being provided with air chamber between the front courage dish on the axis and rear courage dish, the enraged rubber courage of air chamber is outward the polishing roll dish, cause the expansion of enraged rubber courage that the polishing roll dish is fastened on the enraged rubber courage by valve to the air chamber gas injection, thereby realized the purpose of this utility model.

The utility model advantage is, owing to adopt the fixing comparatively thin polishing roll dish of gas expansion type, make the polishing roll dish part can be rough and uneven in surface with body surface, convergent-divergent changes, thereby finish polishing to out-of-flatness surface object, also can be comparatively desirable finish polishing to bending-wood spare surface.And this structure makes polishing roll frivolous, and cost is low, and it is solid also to be easy to cover, and easy to use, polishing effect is good.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 cuts open structural representation in the utility model

The utility model is made up of axis 2 and polishing roll dish 8, between the front courage dish 6 on the axis and rear courage dish 10, be provided with air chamber 11, air chamber is sealed air chamber, air chamber communicates with outdoor by valve 12, tympanites rubber courage 7 is by front and back courage dish and front and rear covers sealed air chamber, the enraged rubber courage of air chamber is outward the polishing roll dish, causing enraged rubber courage to expand by valve 12 to the air chamber gas injection is fastened on the enraged rubber courage polishing roll dish, the courage dish outside, front and back is provided with ladder tooth 4, the dual-side of tympanites rubber courage is squeezed between front and back enclosing cover and the front and back courage dish, the inner, axis both sides is provided with fixedly internal thread 1, and the polishing roll dish is enclosed within the enraged rubber courage outside.Polishing roll dish roll surface thickness is the 1-100 millimeter.

During concrete the making, establish internal thread 1 in order to be connected and fixed with line shaft in the inner, axis 2 both sides.For example axis can be screwed on carpenter's Multi-purpose planer and consist of polishing mechanical.For traditional syndeton event is not repeated.Front courage dish 5 and rear courage dish 10 are established in both sides on axis, are truncated cone-shaped.Establish ladder tooth 4 in the front and back courage dish outside, fixing enraged rubber courage 7 dual-sides of enclosing cover extruding before and after being used for cooperating, make its with front and back courage dish between formation sealed air chamber 11.All with screw 3 both are screwed togather compression between front enclosing cover 5 and front courage dish 6 and rear enclosing cover 9 and the rear courage dish 10.Also enraged rubber disc dual-side is pressed on the ladder tooth simultaneously.One end of valve communicates with air chamber, and the other end is air intake structure, does being not repeated for traditional structure, for example can select bicycle air valve structure etc., can guarantee convenient turnover gas.

Polishing roll dish 8 thickness can be between the 1-100 millimeter, usually select thickness according to length.Its structure can be bonding fine sand on the drum-shaped base fabric, consists of husky roller dish, also can be cloth rewinder roll dish or sandpaper roller dish, can design as required, should guarantee thin and some strength.

During use, polishing roll dish 7 is enclosed within outside the enraged rubber courage, makes the enraged rubber courage solid polishing roll dish of support that expands from valve to chamber inflated, axis is connected with line shaft again, get final product polishing article, the time spent does not unscrew valve and exits and take off or change the polishing roll dish.

In a word, the utility model is simple in structure, and is economical and practical, can be to crooked object or other crooked out-of-flatness surface finish, and it is good to throw fineness, is a kind of corollary equipment of desirable raising object fineness.
