Description

Paperboard printing and drying device

Technical Field

The invention relates to the technical field of printing equipment, in particular to a paperboard printing and drying device.

Background

In the production and processing process of printed matters, for example, a paperboard, a blank paper tape and the like need to be cut and cut according to the specification of a product after being subjected to the pattern printing processing of a printing machine, and because the printing ink (water-based printing ink) contains a large amount of water, the drying of the image-text printing ink printed on the paper tape is necessarily ensured before the cutting and cutting process, and the drying treatment of the printing ink on the printed matters is needed before the printed matters are cut, so that the problem that the surfaces of the printed matters are polluted by the printing ink which is not dried is prevented from being stained on the surfaces of conveying rollers.

The conventional drying device can only dry a single surface generally, has low drying efficiency and cannot fully utilize a heat source; for some carton printed products, such as corrugated paper, it is not suitable for drying by roller curling because it is not easy to bend; when the cardboard was transported through dull and stereotyped conveyer belt, there was the phenomenon of skidding easily, also can have certain influence to the stoving, influenced the feeding, seriously leads to the fact the cardboard to pile up.

Disclosure of Invention

The present invention is directed to solving, at least to some extent, one of the technical problems in the related art. Therefore, one object of the present invention is to provide a drying device for printing paper boards, which facilitates air circulation, hot air circulation, and stable paper board transportation.

The technical scheme of the invention is as follows:

the utility model provides a cardboard printing drying device, includes casing and the conveyer belt of setting in the casing, feed inlet and discharge gate have been seted up at the both ends of casing, are in simultaneously the business turn over notch of conveyer belt has been seted up to feed inlet and discharge gate below, the conveyer belt passes through feed inlet, discharge gate and business turn over notch and encircles the setting and be in the casing, just a plurality of through-holes have been seted up on the drive belt surface the inner chamber of casing installs first thermocouple and second thermocouple respectively at the inner chamber top and the bottom of casing the side of casing has installed the blast orifice of a plurality of horizontal blast air, the external air-blower of blast orifice in the conveyer belt inboard.

Further, the second thermocouple has a higher operating temperature than the first thermocouple.

Furthermore, a supporting plate is attached to the bottom of the upper conveying belt and fixed in the shell.

Furthermore, a plurality of vent holes are formed in the supporting plate, and a fixing plate is fixed to the end side of the supporting plate.

Furthermore, one end of the blast port is provided with a ventilation cavity according to the principle of the supporting plate.

Further, an arc-shaped air deflector is fixed on the inner wall of the shell corresponding to the ventilation air.

Furthermore, in order to facilitate air circulation, a heightening guide block is fixed on the top of the support plate.

The invention has the beneficial effects that: through the arrangement of the air blowing ports, air above and below the conveying belt can flow inwards (flows to the air blowing ports, and air exhausted from the air blowing ports can be rapidly heated), so that the drying of the paper boards arranged on the conveying belt can be promoted, and meanwhile, the paper boards can be attached to the surface of the conveying belt and are not easy to slip; the ventilation air is arranged on the supporting plate, so that the hot air circulation capacity in the shell can be increased, and the heat energy can be fully utilized, so that the power consumption of the two couples can be reduced, and the energy-saving effect is achieved; through setting up bed hedgehopping guide block, can increase the conveyer belt of top and the interval of backup pad, the circulation between backup pad and conveyer belt is followed to the air of being convenient for.
