Description

The multiple new equipment of video disc polishing

The utility model relates to a kind of polishing mechanical device, specifically is meant a kind of multiple new equipment of video disc polishing that is specially adapted to polish old video disc.

At present, the production development of China's video disc player (comprising types such as CD, VCD, LD, DVD and CVD) is very rapid, and use face is almost popularized each family.But because the organism material of the video disc that video disc player uses is plastics, therefore be easy to make disc surface to produce cut or breakage, so that cause that video disc is machine-readable not to be gone out information or read effect relatively poor, reach the laser head that damages video disc player and the order of severity of servo-drive system even.And, feel waste and unfortunate again unavoidably if the video disc of surface generation cut and breakage is like this passed into disuse.

In view of this, the purpose of this utility model is to provide a kind of can polish processing and make the multiple new device of old video disc polishing producing cut and damaged video disc.

Solution of the present utility model is as follows.It has a base plate, a holder is being connected on the base plate, tightly pegging graft in the perforate of holder one and stretching to the column of top, the top of base plate has a crossbeam, one end of crossbeam have fuse with it enclose the column anchor ear of hoop on column, the parallel adjusting gap that is connected with column anchor ear inside of separately leaving abreast of two tail ends of column anchor ear, the screw portion of a degree of tightness regulating wheel is screwed in the screw that two tail ends of column anchor ear offer, screw or loosen this degree of tightness regulating wheel, can be on column with the column anchor ear lock ring of crossbeam, or crossbeam moved up and down the position together with the column anchor ear along column; The crossbeam other end has the dc speed-regulating motor that is connected on the crossbeam, in the upright rotating shaft of dc speed-regulating motor, tight cover is a polishing wheel then, the polishing wheel underneath is equipped with foam-rubber cushion, and with flannelette the foam-rubber cushion hard-pressed bale is rolled on the polishing wheel, and the flannelette outside is with a flannelette anchor ear, the flannelette anchor ear is by being loaded on the screw of its tail end, holding the flannelette anchor ear tightly flannelette and be connected on the polishing wheel,, the water retaining cover that is connected on the dc speed-regulating motor end cap is being housed in polishing wheel, flannelette and flannelette anchor ear periphery; On the crossbeam between dc speed-regulating motor and the column, be equiped with the motor speed control circuit that the one-way SCR by the potentiometer of belt switch and two reverse parallel connections constitutes, one end of the potentiometer in the motor speed control circuit and the silicon controlled control utmost point join, the other end of potentiometer with link together with another silicon controlled control utmost point again after its medial head links to each other, silicon controlled one end that two reverse parallel connections links to each other with the switch that potentiometer has, and the stator winding of two silicon controlled power output ends and dc speed-regulating motor joins.

The utility model with said structure is when concrete the use; motor speed control circuit and the dc speed-regulating motor stator winding that is cascaded are connected the 220V electric main together; open potentiometer has in the motor speed control circuit the power switch and the resistance value of manual adjustments potentiometer then; change the silicon controlled angle of flow; make alignment circuit export stepless adjustable dc voltage; make that dc speed-regulating motor rotation and rotating speed are stepless adjustable; thereby directly drive by polishing wheel; foam-rubber cushion; the rubbing head rotation that flannelette and flannelette anchor ear constitute; the hand-held video disc of operator's this moment and the every continuous pad and the backing plate that place the video disc below; allow rubbing head gently be pressed in the video disc upper surface; processing is polished at the position that produces cut and breakage on the video disc; video disc after the polishing is coated bright protective agent again, has just reached to repair the old purpose that newly can reuse again.In order to polish the convenience of processing, height and position as needs adjustment rubbing head can unclamp the degree of tightness regulating wheel on the beam-end column anchor ear, and moving beam is socketed in residing height and position on the column, after polished head height degree position reaches requirement, again the degree of tightness regulating wheel is screwed.If need to add water or cleaning agent in polishing process, water retaining cover then plays the effect of dash splashproof.Flannelette on the rubbing head with old wearing and tearing after, can disassemble easily and change.

The utility model only needs with shirtsleeve operation and cheap consumption, just can polish again processing newly with producing cut and damaged video disc player video disc, has avoided scrapping easily of old video disc, and the user has saved expense for video disc, has also saved goods, materials and equipments for society simultaneously.Its motor speed control circuit is simple in structure, and is with low cost, simultaneously because positive and negative impulse action all can trigger down, forward and reversely can both control conducting, do not have the reverse breakdown problem, element also raising greatly in service life.

Below in conjunction with drawings and Examples the utility model is further specified.
