The spindle sealing device of the vacuum screen printer in the utility model comprises a bearing base disposed inside a vacuum room, a spindle which is disposed on the bearing base and passes through a baseboard of the vacuum room, as well as a sealing flange and a belt wheel which sleeve on the other end of the spindle in order, wherein the sealing flange is firmly connected on the baseboard and equipped with a C-shaped sealing ring set inside, the C-shaped sealing ring set sleeves the spindle, and a sealing cushion is disposed between the baseboard and the sealing flange. The spindle sealing device of the vacuum screen printer in the utility model can be used in the field of circuit board processing.
Description
Technical field
The utility model relates to a kind of vacuum screen printer sealing device for rotary shaft.
Background technique
Vacuum box domestic demand at vacuum screen printing hole plugging machine is used revolving table, owing to having space between transmission shaft and vacuum box, thereby has affected the sealing of vacuum box.In the past, in vacuum environment, use transmission shaft, often adopt magnetic seal technology to guarantee its sealing, be that rotating ring (soft magnetic material) in magnetic seal device is in contact with one another composition friction pair with stationary ring (magnetic material), bear high-speed friction, realized the sealing between rotor structure and stator structure.This kind of device volume is huge and expensive, and vacuum box volume in described vacuum screen printing hole plugging machine is little, therefore such device does not meet use.
Model utility content
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art exactly, and a kind of vacuum screen printer sealing device for rotary shaft that is applicable to vacuum screen printing hole plugging machine and reduces enterprise's user cost is provided.
The technological scheme that the utility model adopts is: the utility model comprises the bearing support that is arranged in vacuum chamber, be arranged on described bearing support and through the running shaft of the base plate of described vacuum chamber and be set in successively sealing flange and the belt pulley on the described running shaft the other end, described sealing flange is fixedly connected on described base plate and inside is provided with C RunddichtringO group, described C RunddichtringO group is set on described running shaft, between described base plate and described sealing flange, is provided with sealing gasket.
Preferably, described C type sealing group comprises that two pairs are arranged on the C RunddichtringO in the two side walls of front and back in described sealing flange, the relatively outer described C RunddichtringO size in position is large, and described C RunddichtringO is provided with macrolattice Seal cage and can bears the pressure of 0.9kg.
Preferably, described sealing flange is near on described belt pulley one end, dust cover being housed.
The beneficial effects of the utility model are: because the utility model comprises the bearing support that is arranged in vacuum chamber, is arranged on described bearing support and through the running shaft of the base plate of described vacuum chamber and be set in successively sealing flange and the belt pulley on the described running shaft the other end, described sealing flange is fixedly connected on described base plate and inside is provided with C RunddichtringO group, described C RunddichtringO group is set on described running shaft, between described base plate and described sealing flange, is provided with sealing gasket.Described C type sealing group comprise two pairs be arranged in described sealing flange before and after C RunddichtringOs in two side walls, the relatively outer described C RunddichtringO size in position is large, described C RunddichtringO is provided with macrolattice Seal cage and can bears the pressure of 0.9kg.Described C RunddichtringO is by described macrolattice Seal cage, and it is pressed on described running shaft to utilize the inside and outside pressure official post of vacuum chamber, realizes sealing effect together with described sealing gasket.So the utility model guarantees running shaft and have good sealing when rotating, effectively simplified structure, reduce volume, reduced the user cost of enterprise.
Because described sealing flange is near on described belt pulley one end, dust cover being housed.Can effectively protect described sealing flange like this, thereby improve working life of the present utility model.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model.
Embodiment
As shown in Figure 1, on the base plate 1 of vacuum chamber, have through hole, running shaft 2 is through described through hole, make its one end in vacuum chamber, the other end is outside described vacuum chamber, be arranged with bearing support 3 being positioned on the described running shaft 2 of described vacuum chamber, be positioned on the described running shaft 2 outside described vacuum chamber sheathed upper sealing flange 4 and belt pulley 5 successively, described sealing flange 4 is equipped with C RunddichtringO group on the inner position near front and back two walls, and described C RunddichtringO group is set on described running shaft 3, described sealing flange 4 is fixedly connected on described base plate 1 by screw, between described sealing flange 4 and described base plate 1, be also provided with sealing gasket 6, described bearing support 3 and base plate 1 are all fixed in vacuum chamber frame, described sealing flange 4 is fixed on described base plate 1 by described sealing gasket 6, described base plate 1 top is vacuum chamber, bottom is outside atmosphere layer.
Described seal ring group comprises two pairs of C RunddichtringOs 7, be separately positioned on the position of pressing close to its front and back two walls in described sealing flange 4, wherein the diameter of the relatively outer C RunddichtringO 7 in position is larger, and be equipped with macrolattice Seal cage on described C RunddichtringO 7, see through described macrolattice Seal cage and utilize described vacuum chamber inside and outside differential pressure, described C RunddichtringO is close on described running shaft 2, realize sealing, described C RunddichtringO can bear at least the pressure of 0.5kg, and (absolute pressure of bearing in described vacuum chamber is 0.9kg/mm
2).
At described sealing flange 4, be installed with dust cover 8 near described belt pulley 5 one end outer walls, 8 pairs of described seal ring groups of described dust cover play a protective role.
The utility model can be used in circuit board manufacture field.
