Abstract
An automatic back winding type dust preventing belt comprises a support stand, a winding cylinder, a turbination spring, a rolling bearing, plastic covered nylon belts and the like. The device is cooperated with a protecting cover casing of a mechanical appliance, the plastic covered nylon belts are firmly contacted with the inner surface of the protecting cover casing which is adhered with sealed fiber strips, when the moving part of the mechanical appliance moves, one end of the plastic covered nylon belts which are arranged on the two ends of the moving part is stretched, and the other end is back winded automatically, thereby the bare portions of the protecting cover casing of the mechanical appliance are capable of being sealed by the plastic covered nylon belts. The device has the function of back winding automatically with small bulk, light weight, compact structure, no noise and small additional traction power, further the extending and extracting amount is capable of reaching 500-1000 mm. The utility model is applicable to the dust preventing protection of light-duty small-sized digital controlled mechanical processing appliances, precise instruments and electromechanical integration devices which have small installation space, big operating stroke and fast running speed.
Description
Technical field
The utility model relates to a kind of anti-dust protecting device that is used for small-sized numerical controlled machinery process equipment, precision instrument, electromechanical integration equipment.
Background technology
Anti-dust protecting device is the normal service life of protecting mechanical movement class parts such as guide rail in numerical controlled machinery process equipment and general machining equipment, guarantees the appurtenances a kind of commonly used of equipment safety operation.The structure function of anti-dust protecting device, volume size, mounting condition etc. have substantial connection with exercise performance, the assembly structure of machining equipment.Because the kind of machining equipment is many, structural change is bigger, and therefore, the structure and the kind of anti-dust protecting device are numerous and diverse, and function is different.
At present, the anti-dust protecting device product major part on the market all is to design production at the needs of large and medium-sized Digit Control Machine Tool or general electromechanical integration equipment, and the volume and the weight of product are bigger, do not have the automatic rewinding function mostly.Even have the product of automatic rewinding function, its stroke also smaller (being generally less than 300 millimeters), and tensile force is bigger, causes additional drawing force to increase, and is not suitable for small-sized numerical controlled machinery process equipment, precision instrument, electromechanical integration equipment.
Summary of the invention
In order to overcome the deficiency of existing anti-dust protecting device product; the utility model proposes that a kind of volume is little, in light weight, big, the additional drawing force of stroke is less; compact anti-dust protecting device with automatic rewinding function is particularly suitable for using in needing the small-sized numerical controlled machinery process equipment of proofing dust and protecting, precision instrument, electromechanical integration equipment.
The technical scheme that its technical problem that solves the utility model adopts is: the anti-dust lane of automatic rewinding formula is by reel assemblies, the roll shaft assembly, hold-down support (11), movable bearing support (12), cover and mould nylon tape (10) formation, described reel assemblies comprises reel (5), scroll spring (4), axle (9), and rolling bearing (2) and the bearing cap (1) installed at axle (9) two ends, described roll shaft assembly comprises roll shaft (18), roller (16), roll shaft seat board (15) is characterized in that: (9) two external parts of axle in the described reel assemblies, end hold-down support (11) of packing into, the other end movable bearing support (12) of packing into, be wound on covering on reel (5) outer surface and mould nylon tape (10) from stretching out near roll shaft seat board (15) one sides, and be close to roller (16) surface, by screw (13) movable bearing support (12) is fixedlyed connected with hold-down support (11) and be assembled into one.
Hold-down support (11) and movable bearing support (12) provide supporting and location for described reel assemblies, and described roll shaft assembly is moulded nylon tape (10) rolling bearing and location are provided for covering.It is bonding and be wound on reel (5) outer surface to cover an end of moulding nylon tape (10), and the other end can be connected with the movement parts of the plant equipment of needs sealing.Because the resilient force of scroll spring (4), when not having the external force pulling, it tightly is wound on the reel (5); When it is subjected to external force effect stretching, reel (5) overcomes the elastic force of scroll spring (4) and turns round around axle (9), after the external force effect is removed, reel (5), thereby covers and moulds nylon tape (10) and realized the automatic rewinding function around axle (9) revolution in the other direction by the automatic restorability of elasticity of scroll spring (4).
The utility model is when practical application; need be used with the protective cover housing in the plant equipment; and must mounted in pairs at the two ends of proofing dust and protecting position static element (Rack Body), make to cover and mould nylon tape and be close to the inner surface of the protective cover housing that is pasted with the sealing ribbon.When the movement parts (slide block or planker) of plant equipment was mobile, the covering of movement parts two ends moulded nylon tape one end and stretched, and other end automatic rewinding makes the exposed position of opening of plant equipment protective cover housing can be all the time by its tight sealing.
The beneficial effects of the utility model are, its support part is made of cold-reduced sheet punching press (or aluminium alloy compression casting) technology, are fit to produce in enormous quantities, and production cost is lower; Stroke big (500-1000 millimeter), and additional drawing force is little; Compact conformation is reasonable, and noiselessness is particularly suitable for installing space is little, impulse stroke is big, movement velocity is fast small-sized numerical controlled machinery process equipment, precision instrument and electromechanical integration equipment and uses.
