Technical Field

The invention belongs to the field of expanding machines, and particularly relates to a novel expanding machine.

Background

The heat shrinkable tube is generally produced by extrusion, irradiation and expansion, the expansion is an essential process in the production process of the heat shrinkable tube, the expansion modes widely used at present comprise an internal pressure method, a vacuum method and an internal pressure vacuum combination method, and the corresponding expansion modes are respectively selected according to the size and the material of a product.

At present expander in the use, adopt the mode of medium soaking heating to heat the pyrocondensation pipe, more common heating medium is glycerine, but the pyrocondensation pipe surface after the heating can have the oil stain, is difficult to wash, especially when the temperature is lower, the oil stain on surface is more difficult to get rid of. Therefore, a new type of expander is needed to solve the oil stain problem.

Disclosure of Invention

The invention provides a novel expander aiming at the problems provided by the background technology, and the expander adopts an electric heating mode to heat, thereby solving the problem of oil stain.

The technical scheme of the invention is as follows: a novel expander comprises a feeding device, a first heating device, an amplifying device, a discharging device and a cutting device, wherein the first heating device comprises a heating chamber, and the heating chamber comprises an electric heating roller and a driving motor for driving the electric heating roller to rotate.

Furthermore, the heating device also comprises a second heating device, wherein the second heating device also comprises a heating chamber, and the heating chamber internally comprises an electric heating roller and a driving motor for driving the electric heating roller to rotate.

Furthermore, the electric heating roller comprises two rows, wherein one row is a guide roller, the other row is a traction roller, a heat shrink tube channel is arranged between the two rows, and meanwhile, the rotation directions of the two rows of electric heating rollers are opposite.

Furthermore, a hot air knife blowing hot air towards the heat shrink tube channel is further arranged in the heating chamber.

Further, the heat shrinkable tube comprises a printing device for printing characters on the heat shrinkable tube.

Furthermore, amplification device includes the vacuum chamber, simultaneously, be provided with the jetter in the vacuum chamber for carry out effectual washing to the pyrocondensation pipe, thereby make the sleeve pipe neatly spend and promote by a wide margin.

Furthermore, the feeding device and the discharging device are both belt tractors.

Further, cutting device includes the locator, can realize automatic accurate meter rice and cut.

The invention has the beneficial effects that:

1. the expander adopts an electric heating mode, so that the neatness of the product is greatly improved, the later cleaning is reduced, and the expenditure of manpower and material resources is reduced;

2. in the enlarging device, a spray washing device is also added, so that the smoothness of the sleeve can be further improved.

Drawings

The invention is further described with reference to the following figures and examples:

FIG. 1 is a schematic structural view of the expander;

wherein: 1. the device comprises a feeding device, 2, a first heating device, 3, a second heating device, 4, an amplifying device, 5, a discharging device, 6 and a cutting device.
