Abstract
The utility model discloses a pyrocondensation pipe extension fixture, include mould mouth, sizing pipe and cooler bin, the front end of sizing pipe links to each other with the rear end of mould mouth, and the preceding lateral wall of cooler bin and fixed mutually with preceding lateral wall is passed to the rear end of sizing pipe, has offered pipe inlet in the mould mouth, and the mouth of pipe has been offered out to the lateral wall behind the cooler bin, and the sizing outside of tubes is equipped with the vacuum cover along sizing pipe length direction cover, and the space that forms is real empty room between the pipe wall that this vacuum cover and sizing were managed, and the vacuum is put in and has been offered the vacuum suction inlet, has offered a plurality of vacuum hole on the pipe wall of sizing pipe, seted up the inlet opening on the roof of cooler bin, the apopore has been seted up to the bottom, is provided with horizontal porous distributing plate in the cooler bin, and the mounted position of this porous distributing plate is higher than to go up in sizing outside of tubes week follows, make the cooling water through the mode that sprays and water direct contact, the cooling effect is good, and product axial shrinkage factor is little.
Description
Technical field
This utility model relates to a kind of device for expanding thermal shrinkage tube.
Background technology
Expansion is as the core process in heat-shrink tube production process, during expansion, heat-shrink tube after expansion is cooled down or allows cooling water enter inside dilatation mold simultaneously and cools down by general logical supercooled water indirectly, to keep its stability expanded and seriality, but, heat-shrink tube after expansion can not be cooled down by current cooling structure fully, make the heat-shrink tube after expansion also in soft state, under the effect of external traction force, it is easy to produce axial tension, the axial shrinkage rate causing heat-shrink tube becomes big, and product quality declines.
Utility model content
This utility model provides a kind of device for expanding thermal shrinkage tube so that cooling water directly contacts with water by the way of spray, and cooling effect is good, product axial shrinkage rate is little.
In order to solve the problems referred to above, the technical solution adopted in the present invention is such, a kind of device for expanding thermal shrinkage tube, including mould mouth, sizing tube and cooler bin, the front end of sizing tube is connected with the rear end of mould mouth, the rear end of sizing tube through cooler bin front side wall and fixes with front side wall, inlet pipe mouth is offered in mould mouth, cooler bin rear wall offers outlet spout, sizing tube is outer is arranged with vacuum envelope along sizing tube length direction, between this vacuum envelope and tube wall of sizing tube, formed space is vacuum chamber, suction mouth is offered on vacuum envelope, several vacuum holes are offered on the tube wall of sizing tube；Offering inlet opening on the roof of cooler bin, bottom offers apopore, is provided with horizontal multihole distributor in cooler bin, and the installation site of this multihole distributor is higher than edge on sizing tube periphery.
Preferably, the middle part of cooler bin left and right sides wall is arc-shaped.
Preferably, outlet spout be provided around absorbent cotton.
Preferably, the diameter of inlet pipe mouth is less than the internal diameter of sizing tube.
Beneficial effect: enter the cooling water of cooler bin after multihole distributor effect, form waterfall curtain, heat-shrink tube is contacted fully with water, improve cooling effectiveness, reduce heat-shrink tube axial shrinkage rate, ensure the quality of product, additionally, mode due to cooling hydromining spray, when heat-shrink tube is cooled down, control the lower edge less than sizing tube inner circumferential of the liquid level in cooler bin, after ensure that heat-shrink tube is cooled down by cooling water, almost all outlet bottom cooler bin goes out, the most a small amount of water is sucked entrance sizing tube formation by vacuum and is wrapped in the water membrane outside heat-shrink tube, play the effect of lubrication heat-shrink tube.
Accompanying drawing explanation

Fig. 2 is the A-A sectional view of Fig. 1.
Detailed description of the invention
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment is only used for explaining this utility model, is not intended that the restriction to this utility model protection domain.
See Fig. 1, a kind of device for expanding thermal shrinkage tube, including mould mouth 1, sizing tube 2 and cooler bin 3, the front end of sizing tube 2 is connected with the rear end of mould mouth 1, the rear end of sizing tube 2 through cooler bin 3 front side wall and fixes with front side wall, inlet pipe mouth is offered in mould mouth 1, cooler bin 1 rear wall offers outlet spout 4, sizing tube 2 is outer is arranged with vacuum envelope 3 along sizing tube length direction, between this vacuum envelope 3 and tube wall of sizing tube 2, formed space is vacuum chamber, offer suction mouth 5 on vacuum envelope 3, the tube wall of sizing tube 2 offers several vacuum holes 6；Offering inlet opening 7 on the roof of cooler bin 3, diapire offers apopore 8, is provided with horizontal multihole distributor 9 in cooler bin 3, and the installation site of this multihole distributor is higher than edge on sizing tube periphery.
Profile in order to make cooler bin left and right sides wall contact with heat-shrink tube is suitable with the profile of heat-shrink tube, thus heat-shrink tube is played styling, and as indicated with 2, the middle part of cooler bin left and right sides wall is arc-shaped.
The effect of water and sealing in order to absorb heat-shrink tube surface, outlet spout be provided around absorbent cotton 10.
In order to reduce vacuum leak, the diameter of inlet pipe mouth is less than the internal diameter of sizing tube.
Heat-shrink tube to be expanded is entered in sizing tube 2 by inlet pipe mouth 3, owing to offering several vacuum holes 6 on the tube wall of sizing tube 2, suction mouth 5 is offered on vacuum envelope 3, evacuation at suction mouth 6, vacuum is formed in sizing tube 2, heat-shrink tube to be expanded is expanded by pull of vacuum when sizing tube 2, expand later heat-shrink tube and enter cooling and shaping in cooler bin 3, cooling water is after multihole distributor 9 acts on, form waterfall curtain, after heat-shrink tube is sufficiently cooled, go out from outlet spout 4, wherein, control the lower edge less than sizing tube 2 inner circumferential of the liquid level in cooler bin 3, ensure that the outlet bottom cooler bin 3 of the water almost all after cooling down heat-shrink tube goes out, do not enter in sizing tube 2.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
