Problems solved by technology

[0003] However, when the above-mentioned heat-shrinkable expansion system heats the heat-shrinkable tube, a single heat-shrinkable tube passes through the through hole and is heated in the heating furnace. Since the heat-shrinkable tube absorbs very little heat energy, the heat loss of the heating furnace is mainly The heat energy lost to the outside world, this heating method causes a lot of heat energy loss

[0031] see figure 1 , which discloses the first embodiment of the heat-shrinkable tube expansion system of the present invention, including a conveying device 10 , a heating furnace 20 , an expanding device 30 and a pulling device 40 .

[0032] In this embodiment, the conveying device 10 includes three conveying rollers 11 and a driving motor (not shown) for driving the conveying rollers 11, the three conveying rollers 11 are arranged adjacently, and the heat-shrinkable tubes 50 can be respectively arranged on the two conveying rollers. Between adjacent conveying rollers 11.

[0033] The heating furnace 20 is provided with a through hole 21 passing through two ends of the heating furnace 20 . The heating furnace 20 can be an infrared, far infrared or vacuum heating furnace.

[0034] The expansion device 30 is roughly cylindrical, and has a mold sleeve 31 and two mold cylinders 32 disposed in the mold sleeve 31. The mold cylinder 32 is provided with a plurality of air holes 3...

[0045] see Figure 5 , which discloses the fourth embodiment of the heat-shrinkable tube expansion system of the present invention, this embodiment is similar to the third embodiment, the difference is that a deviation correction device 60 is provided between the heating furnace 20 and the two expansion devices 30', The device 60 can detect whether the heat shrinkable tube 50 deviates and correct the deviation of the heat shrinkable tube 50 .

[0046]In summary, the heat-shrinkable tube expansion system of the present invention includes a conveying device 10 , a heating furnace 20 , an expanding device 30 and a traction device 40 . In the tube heating method, since the heat-shrinkable tube 50 absorbs very little heat energy, the heat energy loss of the heating furnace 20 is mainly concentrated in the heat energy dissipated from the heating furnace 20 to the outside. Compared with tubes, the heat loss of the heating furnace 20 basically does not change, and the number of heate...

Abstract

The invention provides a method for heating shrinkable tubes. The shrinkable tubes are heated by a heating furnace; a through hole is formed in the heating furnace; and at least two shrinkable tubes penetrate through the through hole and are heated in the heating furnace. As the heat energy absorbed by the shrinkable tubes is extremely little, the heat energy loss of the heating furnace is mainly the heat energy dissipated from each heating furnace to the outside and is basically not changed when used for heating two shrinkage tubes by the heating furnace compared with that required for heating one shrinkage tube by the heating furnace, and more than two shrinkage tubes are heated by the heating furnace, the method for heating the shrinkable tubes can ensure that the heating furnace saves nearly more than half of the heat energy. The invention also provides a shrinkable tube expanding system using the method for heating the shrinkable tubes, and the system comprises a conveying device, a heating furnace, an expanding device and a traction device, and adopts the method for heating the shrinkage tubes by heating at least two shrinkage tubes in the heating furnace while the two shrinkage tubes penetrate through the through holes, so that the heating furnace can save nearly half of the heat energy, the expanding speed is high and the efficiency is high.

Description

technical field [0001] The invention relates to a heating method and an expansion system using the heating method, in particular to a heat shrinkable tube heating method and a heat shrinkable tube expansion system using the heating method. Background technique [0002] At present, the heat-shrinkable tube expansion system includes a conveying device, a heating furnace, an expanding device and a traction device. When the heat-shrinkable tube expansion system is working, the heat-shrinkable tube is transported by the conveying device in a single form, heated by the heating furnace, and then enters the expansion device for expansion. After the heat-shrinkable tube is expanded, it is drawn out by the traction device. The heating furnace is provided with through holes running through its two ends, and the product to be heated passes through the through hole, and the heating product is heated by the heat in the heating furnace. [0003] However, the above-mentioned heat-shrinkabl...
