Embodiment
Below, in conjunction with accompanying drawing cylinder sealing of the present invention is elaborated with the packing ring liner.
The packing ring liner is used in cylinder sealing of the present invention; Will be for keeping the part of both sides of the edge 101,102 that certain width W is cut into the fiber felt 100 of certain-length; The folded lengthwise of the above-mentioned fiber felt 100 in edge is also made; So that the both sides of the edge of fiber felt 100 form dual structure, the part of the side margin in the above-mentioned folding both sides of the edge forms the extending portion 103 of the part that can cover the opposite side edge part, and on the surface of above-mentioned extending portion 103; Make formation telescopic band 104 along the length direction of fiber felt 100; In addition, above-mentioned edge has two terminal parts of the fiber felt 100 of dual structure to be made with shaft-like contact mutually, to eliminate mutual level difference.
As shown in Figure 1; The packing ring liner is used in the cylinder sealing of the present invention of above-mentioned formation; Under the situation of keeping certain width W, cut fiber felt 100 by Len req; And the cutting of the width W of above-mentioned fiber felt 100 and length cuts according to the width and the external diameter at the sealing position of want sealing objects cylinder.
As shown in Figure 2, the above-mentioned fiber felt that cuts 100 at first at outer surface one side margin 101 of fiber felt 100, is made telescopic band 104 along the length direction of fiber felt 100.Its reason is, and is as shown in Figure 6, at the sealing position of sealed cylinder D, promptly during peripheral part, gives robustness not only for fiber felt 100, and, improve tightness through the sealing that improves telescopic band 104.
The material of above-mentioned telescopic band 104 can be a kind of in rubber with elastic force, synthetic resin, the silicon, and, can be as required at the bonding telescopic band protective material 105 of the another side of telescopic band 104, to improve the robustness of telescopic band 104.
The reason of bonding above-mentioned telescopic band protective material 105 is, if raising cylinder D sealing position, i.e. the sealing force of peripheral part and plucking felt fiber 100 then because of the stretching of telescopic band 104, might produce slight crack and rupture on telescopic band 104.In addition, preferably, above-mentioned telescopic band protective material 105 adopts grenadine shape fiber.
Through said process,, make telescopic band 104 along the length direction of fiber felt at outer surface one side margin 101 of fiber felt 100; Then, as shown in Figure 3, with the above-mentioned opposite side edge 102 of not making the fiber felt 100 of telescopic band 104; Fold to the another side direction along its length and make, its reason is to make fiber felt 100 through stack; Improve the robustness of fiber felt 100; And, as shown in Figure 6, the face contact force of preceding eyelid retractor that raising contacts with the forward and backward end face of cylinder D and back eyelid retractor.
The folding width at the opposite side edge 102 of above-mentioned fiber felt 100 is the width that do not reach the length direction central line of the fiber felt 100 that has cut, and its reason is, during the side margin that below folding making, will explain, prevents that fold section is overlapped.
If above-mentioned fold section is overlapped, then reduces the sealing force of cylinder, thereby need prevent to produce offset because of producing offset.
Accomplish the making after the operation of opposite side of fiber felt 100 through said process, then, with the part of outer surface one side of the fiber felt of making telescopic band 104 100; With the above-mentioned opposite side edge of making 102 overlapping making; And form extending portion 103 from sewing line to marginal end portion, and the reason that forms extending portion 103 is, as shown in Figure 6; For making the sealing position of extending portion 103 around cylinder D, promptly peripheral part seals.
At this moment; Preferably; The width W of above-mentioned extending portion 103 ' with the above-mentioned opposite side edge of fiber felt 100 to the folding border width W of another side direction " identical or big than it, its reason is, if the width W of extending portion 103 ' less than the width W that above-mentioned opposite side edge 102 is folded to the another side direction "; Then because of around the corresponding minimizing of area of cylinder D, thereby reduce sealing force.
Through on say that process is folding and make after above-mentioned two edges; As shown in Figure 5, be in contact with one another two terminal parts of the fiber felt 100 of making completion and make to be integrally formed, its reason is; As shown in Figure 6, closely the forward and backward end of pinch roller D seals.
In addition, be in contact with one another the method for two terminal parts of above-mentioned fiber felt 100, be preferably mutual butt joint, and its reason be, the attachment portion of portion does not form offset endways.
If the attachment portion in above-mentioned end portion forms offset, then reduce the sealing force of cylinder, thereby need prevent to produce offset because of the offset that is produced.
In addition; Second fiber of one or more in first fiber of one or more in above-mentioned fiber felt 100 mixing use mixing hairs of the present invention, cotton, the fiber crops and mixed polyester, acrylic ester, nylon, polyurethane, the polypropylene; Its reason is; Prevent the wear resistance and the heat resistance of fiber felt 100, and possess certain stretchability, thus the sealing force of raising cylinder.
The mutual mixed proportion of above-mentioned first fiber and second fiber is first fiber, 20～60 weight %: second fiber, 40～80 weight %, and its reason is; If first fiber was looked into 60 weight %; Stretchability can't reach the expection requirement, and if second fiber surpasses 80 weight %, then wear resistance, static electricity resistance and heat resistance can't reach the expection requirement; And preferably, the mutual mixed proportion of first fiber, second fiber is 20～60 weight %: 40～80 weight %.
In addition, make the surface of the fiber felt 100 of above-mentioned telescopic band 104, before making telescopic band 104, heat-treat so that its surface smartens up, its reason is, and is more coarse because of the surface of fiber felt 100, therefore, eliminates its rough touch.In addition, above-mentioned heat treatment method is the flatiron that utilizes flatiron.
