Abstract
The present invention relates to the buffering component on a kind of textile manufacturing machine, particularly relate to a kind of slow release air cylinder.A kind of slow release air cylinder, comprises cylinder body and piston; The bottom of described cylinder body has bleeder port; Sheathed seal ring is fixed in the front end of described piston; Seal convexity is enclosed in the outwardly formation one in side, outer 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.Usefulness of the present invention: seal ring contacts with cylinder body face, adapts to groove and seal convexity and inboard wall of cylinder block can be made fully to adapt to; The setting of support ring, makes piston and cylinder body remain concentric, while further lift-off seal effect, is omitted the use of piston sleeve; Cushion pad can effectively prevent piston from contacting with the hard of cylinder body, and extend cylinder working life, the setting of vent slot, when cushion pad contacts with cylinder base, makes cushion pad each position air pressure identical, effectively prevent the cushion pad caused because of negative pressure and comes off.
Description
Technical field
The present invention relates to the buffering component on a kind of textile manufacturing machine, particularly relate to a kind of slow release air cylinder.
Background technique
Slow release air cylinder is mainly used in printing, Automated condtrol etc. and needs tension force control mechanically; by the effect of air pressure; make the relative movement between mechanical part reach the effect of a buffering, be beneficial to the control of Thermodynamic parameters power, be also conducive to the protection to mechanical part.
Summary of the invention
The invention provides that a kind of structure is simple, good sealing effect and the slow release air cylinder of long service life.In order to realize foregoing invention object, present invention employs following technological means:
A kind of slow release air cylinder, comprises cylinder body and piston; The bottom of described cylinder body has bleeder port; Sheathed seal ring is fixed in the front end of described piston; Seal convexity is enclosed in the outwardly formation one in side, outer 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 be slidably matched with inboard wall of cylinder block; The both sides being positioned at seal ring that two support rings are coaxial respectively.
As preferably, described support ring has breach.
As preferably, an annular cushion pad is installed at the top of described piston; The front surface of described cushion pad has the vent slot inside and outside connected ring.
As preferably, described vent slot has four, is evenly distributed in cushion pad circumferentially, and all towards the ring heart.
Beneficial effect of the present invention is: seal ring contacts with cylinder body face, adapts to groove and seal convexity and inboard wall of cylinder block can be made fully to adapt to, thus improve cylinder seal effect; The setting of support ring, makes piston and cylinder body remain concentric, while further lift-off seal effect, is omitted the use of piston sleeve, and structure is simple and save cost of production; Cushion pad can effectively prevent piston from contacting with the hard of cylinder body, and extend cylinder working life, the setting of vent slot, when cushion pad contacts with cylinder base, makes cushion pad each position air pressure identical, effectively prevent the cushion pad caused because of negative pressure and comes off.

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, detailed description is made to the preferred implementation of a kind of slow release air cylinder of the present invention:
As shown in Figures 1 to 4, this slow release air cylinder mainly comprises cylinder body 1 and piston 2 two-part.Cylinder body 1 is made up of Chemical enhancement POM, and its bottom position arranges a bleeder port 6, in order to slowly to discharge gas in cylinder body 1, thus makes to reach a buffer function between piston 2 and cylinder body 1.
Piston 2 main body is made up of phenolic resin, its front end is offered successively from front to back and is supported annular groove, seal groove, support annular groove three circular groove concentric with cylinder body 1 inwall, in seal groove, seal ring 4 is installed, seal ring 4 is made up of nitrile rubber, seal convexity 42 is enclosed in the outwardly formation one of rear side of its outer, and 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 body adapts to groove 42, and the notch adapting 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 seal convexity 42 and cylinder body 1 inwall can be made fully to adapt to, thus improve cylinder seal effect.
Two on piston 2 support in annular groove, fixed installation support ring 3, and support ring 3 is also made up of POM, its ring body has a breach 31, after support ring 3 installation is fixing, its radius is identical with cylinder body 1 inwall radius, thus 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 remain concentric with cylinder body 1, while further lift-off seal effect, is omitted the use of piston sleeve, and structure is simple and save cost of production.
On the front end of piston 2, the cushion pad 5 that concentric fixed installation one is annular, cushion pad 5 is made up of TPU.On the front-end face of cushion pad 5, have vent slot 51, four road vent slot 51 inside and outside four road connected rings towards the ring heart, and be evenly distributed on anchor ring.Cushion pad 5 can effectively prevent piston 2 from contacting with the hard of cylinder body 2, extend cylinder working life, the setting of vent slot 51, cushion pad 5 is with when contacting bottom cylinder body 1, make cushion pad 5 each position air pressure identical, effectively prevent the cushion pad 5 caused because of negative pressure and be bonded on cylinder body 1 and cause it to come off.
