Description

Tube-shaped polyurethane artificial skin making device

The utility model relates to a kind of tubulose can being weaved cotton cloth and makes the device of tubulose polyurethane artificial skin.

The manufacturing installation of traditional polyurethane artificial skin is the tabular with predetermined retractility to be weaved cotton cloth impregnated in one and contain in the dipping tank of polyurethane resin and solvent, after evenly flooding, send into the exchange of carrying out water liquid and solvent in the coagulating basin again, and the urethane resin layer that is overlayed on whole cloth periphery is suitably solidified, and then send in the rinsing bowl with the mobile remaining solvent that water-washes away, process oven dry at last, and make this urethane resin layer form posterior limiting.

Said manufacturing installation above utilizing, though can produce the polyurethane artificial skin,, plane cloth can only be made plane polyurethane and make skin, then can not it also be made the polyurethane artificial skin of tubulose for weaving cotton cloth of tubulose with this method.

The purpose of this utility model is to provide a kind of manufacturing installation of tubulose polyurethane artificial skin, thus said problem above solving.

Manufacturing installation according to manufacturing tubulose polyurethane artificial skin provided by the utility model comprises: a dipping tank, a coagulating basin, a rinsing bowl, a drying mechanism and delivery element.Wherein, the bottom of dipping tank has a through hole that connects this bottom, this through hole is cone shape axle by a top and passes through, has a gap between this axle and the through hole peritreme, the tubulose that flattens is weaved cotton cloth to be enclosed within along the guiding of cone shape axle top and is input in the dipping tank in a tubular form on the axle, after the dipping polyurethane mixed liquor, utilize through the gap between dipping tank bottom through hole and the axle, the periphery that tubulose is weaved cotton cloth forms the urethane resin layer that one deck has predetermined thickness.

Of the present utility model again on the other hand, a kind of manufacturing installation of making tubulose polyurethane artificial skin provided by the utility model, wherein, one section of axle that passes dipping tank bottom through hole is the axle of convergent from top to bottom, utilize this axle suitably to move up or down, and the through hole of adjustment dipping tank bottom and the gap between the axle can make the tubulose peripheral coating of weaving cotton cloth have suitable thickness.

Hereinafter will be described in detail the utility model with preferential embodiment of the present utility model in conjunction with the accompanying drawings, wherein:

Fig. 1 is the front view of device of the present utility model;

Fig. 2 is the top view of the utility model roller and axle;

Fig. 3 is the side view of the utility model roller and axle;

Fig. 4 is to use the utility model to make the flow chart of tubulose polyurethane artificial skin;

Fig. 5 is the side view of the utility model roller bracing frame and axle.

See also Fig. 1, preferential embodiment of the present utility model includes the delivery element between a dipping tank 2, a coagulating basin 3, a rinsing bowl 4, a drying mechanism 5 and each mechanism substantially.Wherein, the mixed liquor of pack in this dipping tank 2 polyurethane resin and various auxiliary agent, solvent then has suitable water liquid in coagulating basin 3 and the rinsing bowl 4.Characteristics of the present utility model are that these dipping tank 2 bottoms have a through hole 21, and have an axle 6.The top of this axle 6 has a cone shape tapering 61, connects the rake 62 with a downward convergent between the bottom in tapering 61 and the axle 6.With two groups of rollers, 71,72 difference this tapering 61 of clamping and rake 62 periphery suitable positions, convexedly stretch in the immersion trough 2 to support axle 6, and make one section portion 64 of axle 6 pass through through hole 21.When this section 64 is passed through through hole 21, just can and the peritreme of through hole 21 between have a gap 65.

Above-mentioned these two groups of

rollers

71,72 shown in Fig. 2,3, the peripheral position of the suitable diameter in first group of roller 71 clamping tapering 61, the peripheral position of the suitable diameter of 72 clamping rakes 62 of second group of roller.Wherein, each

outrigger shaft

73,74 of organizing

roller

71,72 connects respectively between 75,76, two groups of

gear trains

75,76 of gear train of one group of transmission of intermeshing and then connects with suitable driving gear set 77, just can make this two groups of rollers, 71,72 run-in synchronisms; Certainly, respectively has suitable bracing frame 8 on this

outrigger shaft

73,74, in order to support respectively this

roller

71,72.

About its operating process, please cooperate and consult figure and Fig. 4.Yarn, line etc. is made into the tubulose with retractility weaves cotton cloth and is delivered to the tapering 61 on axle 6 tops by delivery end.When this tubulose is weaved cotton cloth and exported by output, be flat.When penetrating on the axle 6, just strutted and form tubulose by axle 6 when being the weaving cotton cloth through this tapering 61 most advanced and sophisticated guidings of flat.This tubulose is weaved cotton cloth because of two groups of rollers, 71, the 72 rollings conveying downwards of this tapering 61 and rake 62 peripheries, and progresses into downwards in the dipping tank 2 along axle 6.So, this shape with pipe of just weaving cotton cloth impregnated in contain polyurethane resin and help, in the mixed liquor of solvent.Certainly, this tubulose is weaved cotton cloth and is also still continued slowly to carry downwards in containing the dipping mixed liquor.Weave cotton cloth meeting through the gap 65 between dipping tank 2 bottom through holes 21 and the axle 6 so be immersed in the tubulose of polyurethane mixed liquor, and be subjected to the restriction in gap 65, and the periphery lining layer of even polyurethane mixed liquor that tubulose is weaved cotton cloth.Certainly, weave cotton cloth when impregnated in the polyurethane mixed liquor, also can infiltrate an amount of mixed liquor on its tube wall when this tubulose.

Thereafter, this periphery has applied the tubulose of layer of even polyurethane mixed liquor and has weaved cotton cloth, continue to send in a tubular form in the coagulating basin 3 so that and water wherein and help, solvent exchanges, and these mixed liquors suitably solidified.Since tubulose weave cotton cloth enter coagulating basin 3 foremost the time, having water liquid enters in the pipe, the inside and outside surface of pipe just all has water liquid, make the water hydraulic power on the pipe surfaces externally and internally identical, reason tube outer surface water hydraulic power and the still uncured tubulose of polyurethane resin that flattens on it is weaved cotton cloth not so just can make the helping of the polyurethane mixed liquor that infiltrates on this tube wall, solvent and the interior water liquid of this pipe exchange.Again, this helps, solvent because the amount of the mixed liquor on this tube wall of infiltration also not quite, is easy to remove fully.Collapsiblely be tabular and transfer out so weave cotton cloth, and continue to deliver in the rinsing bowl 4 through the tubulose behind the coagulating basin 3, so as with the remnants of tube outer surface help, solvent further washes.Dry at last, just reach the purpose of utilizing the utility model to make tubulose polyurethane artificial skin.Certainly, dried in drying mechanism by the tubulose leatheret that rinsing bowl 4 transfers out, used dryer is configurable with a vacuum pump, so that residual water liquid in the pipe of this tubulose leatheret is thoroughly drained.

Certainly, the utility model is not to be confined to top said embodiment.As shown in Figure 5, one section portion 64 of passing through through hole 21 on axle 6 can be made into tapered shape from top to bottom, and be used for supporting respectively this roller 71, then can be provided with on 72 the bracing frame 8 in order to adjust the adjusting lever 81 that bracing frame rises or descends, so that two groups of

rollers

71,72 rise or descend moves, thereby suitably clamping and adjust axle 6 and move up or down, and its size also can be adjusted in the gap that peritreme forms 65 that makes axle 6 pass through the through hole 21 of one section portion 64 of through hole 21 and dipping tank 2 bottoms, so just can change the weave cotton cloth thickness of the peripheral urethane resin layer that forms of tubulose.
