Abstract
The invention relates to a buffering part on textile machinery, in particular to a slow release air cylinder. The slow release air cylinder comprises a cylinder body and a piston, wherein an air discharge hole is formed in the bottom of the cylinder body; a seal ring is fixedly sleeved at the front end of the piston; a circle of seal bulge is formed by outwards protruding at one side of the outer edge of the seal ring; the top of the seal bulge is contacted with the inner wall face of the cylinder body; a circle of adaptive groove is formed inside the seal ring in a concentric way. The slow release air cylinder has the beneficial effects that the seal ring is contacted with the face of the cylinder body, the seal bulge is fully adaptive to the inner wall of the cylinder body by the adaptive groove, a supporting ring is arranged, so the piston and the cylinder body are always concentric, the sealing effect is further improved, and the application of a piston sleeve is omitted; a buffering cushion is used, the rigid contact between the piston and the cylinder body is effectively avoided, the service life of the air cylinder is prolonged; as a vent groove is arranged, when the buffering cushion is in contact with the bottom of the cylinder body, the air pressure at each part of the buffering cushion is equal, and the buffering cushion is effectively prevented from falling off due to negative pressure.
Description
Technical field
The present invention relates to the buffering component on a kind of textile manufacturing machine, relate in particular to a kind of slowly-releasing cylinder.
Background technique
Slowly-releasing cylinder is mainly used in printing, automation control etc. need to have tension force to control mechanically; by the effect of air pressure; make relative movement between mechanical part reach the effect of a buffering, be beneficial to the control to interaction force, be also conducive to the protection to mechanical part.
Summary of the invention
The invention provides the slowly-releasing cylinder of a kind of simple in structure, good sealing effect and long service life.In order to realize foregoing invention object, the present invention has adopted following technological means:
A cylinder, comprises cylinder body and piston; The bottom of described cylinder body has bleeder port; The fixing sheathed seal ring of front end of described piston; The outwardly formation one circle seal convexity of outer one side of described seal ring; The top of described seal convexity contacts with inboard wall of cylinder block face; The circle that has concentric in described sealing circle body adapts to groove.
As preferably, the front end of described piston arranges two support rings that are slidably matched with inboard wall of cylinder block; Two support rings are coaxial both sides that are positioned at seal ring respectively.
As preferably, on described support ring, have breach.
As preferably, an annular cushion pad is installed at the top of described piston; The front surface of described cushion pad has the inside and outside vent slot of connected ring.
As preferably, described vent slot has four, be evenly distributed on cushion pad circumference, and all towards the ring heart.
Beneficial effect of the present invention is: seal ring contacts with cylinder body face, adapts to groove and can make seal convexity and inboard wall of cylinder block fully adapt to, thereby promoted cylinder seal effect; The setting of support ring, makes piston and cylinder body remain concentric, further when lift-off seal effect, and the use of also having omitted piston sleeve, simple in structure and saved cost of production; Cushion pad can effectively prevent that piston from contacting with the hard of cylinder body, extends cylinder working life, and the setting of vent slot, when cushion pad contacts with cylinder base, makes each position air pressure of cushion pad identical, has effectively prevented from coming off because of the cushion pad that negative pressure causes.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of slowly-releasing cylinder of the present invention;
Fig. 2 is the structural representation of seal ring 4;
Fig. 3 is the structural representation of support ring 3;
Fig. 4 is the structural representation of cushion pad 5.
Embodiment
Below in conjunction with accompanying drawing, the preferred implementation of a kind of slowly-releasing cylinder of the present invention is made to detailed description:
As shown in Figures 1 to 4, this slowly-releasing cylinder mainly comprises cylinder body 1 and piston 2 two-part.Cylinder body 1 strengthens POM by chemistry to be made, and its bottom position arranges a bleeder port 6, in order to the interior gas of slow discharge cylinder body 1, thereby makes to reach between piston 2 and cylinder body 1 buffer function.
Piston 2 main bodys are made by phenolic resin, its front end is offered successively from front to back and is supported annular groove, seal groove, three circular grooves concentric with cylinder body 1 inwall of support annular groove, seal ring 4 is installed in seal groove, seal ring 4 is made by nitrile rubber, the outwardly formation one circle seal convexity 42 of rear side of its outer, the radius of seal convexity 42 is slightly larger than the radius of cylinder body 1 inwall.The circle that has concentric in seal ring 4 bodies adapts to groove 42, and the notch that adapts to groove 42 is positioned on the trailing flank of seal ring 4.Seal ring 4 contacts with cylinder body 1 internal face, adapts to groove 42 and can make seal convexity 42 and cylinder body 1 inwall fully adapt to, thereby promoted cylinder seal effect.
Two on piston 2 are supported in annular groove, fixed installation support ring 3, and support ring 3 is also made by POM, on its ring body, have a breach 31, after support ring 3 installations are fixing, its radius is identical with cylinder body 1 inwall radius, thereby support ring 3 and cylinder body 1 inwall are slidably matched.Breach 31 facilitates the installation of support ring 3, is conducive to that support ring 3 is adaptive to be anchored on piston 2 simultaneously.The setting of support ring 3, makes piston 2 and cylinder body 1 remain concentric, further when lift-off seal effect, and the use of also having omitted piston sleeve, simple in structure and saved cost of production.
On the front end of piston 2, concentric annular cushion pad 5 of fixed installation, cushion pad 5 is made by TPU.On the front-end face of cushion pad 5, have the inside and outside vent slot 51， tetra-road vent slots 51 of four road connected rings towards the ring heart, and be evenly distributed on anchor ring.Cushion pad 5 can effectively prevent that piston 2 from contacting with the hard of cylinder body 2, extend cylinder working life, the setting of vent slot 51, when cushion pad 5 contacts with cylinder body 1 bottom, make cushion pad 5 each position air pressure identical, effectively prevented that the cushion pad 5 causing because of negative pressure is bonded on cylinder body 1 and caused it to come off.
