Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1-4 is please referred to, the utility model provides a kind of technical solution:

A kind of paper machine print paper injection blower device, including the first drying cylinder 1, the second drying cylinder 2 and third drying cylinder 3, described first Drying cylinder 1 and the second drying cylinder 2 are in same horizontal line, and the third drying cylinder 3 is being located at the first drying cylinder 1 and 2 center of the second drying cylinder just Lower section is equipped with guide roller 8, is equipped with the first scraper 9, institute on the left of the guide roller 8 between the third drying cylinder 3 and the first drying cylinder 1 It states and is equipped with the 4th dry net deflector roll 7 between the second drying cylinder 2 and third drying cylinder 3, and its left side is equipped with the second scraper 10, the third is dried Cylinder 3 includes cylinder body 14, and 14 inner sidewall of cylinder body is fixedly connected with spiral heat absorption piece 13, and the 14 right side input terminal of cylinder body is fixed It is connected with steam input pipe 15, the 14 left side output end of cylinder body is fixedly connected with steam cooling tube 16, and steam cooling tube 16 It is connected to the first scraper 9, first scraper 9 and 10 upper and lower ends of the second scraper are fixedly connected to air nozzle 11 and lower spray Gas nozzle 12,3 upper left corner of third drying cylinder are equipped with the first dry net deflector roll 4, are symmetrically arranged with the second dry net below the third drying cylinder 3 Deflector roll 5 and the dry net deflector roll 6 of third.

The spiral heat absorption piece 13 is hollow structure, and spiral heat absorption piece 13 is uniformly distributed to form heat absobing channel a between each other, When drying cylinder during exercise, heat absobing channel a because drying cylinder rotate generate vortex, increase hot steam residence time in cylinder body, more preferably The cylinder body that is transferred to by uniform thermal power, the upper air nozzle 11 and lower air nozzle 12 are identical, and are 5-10, the upper jet Mouth 11 and lower air nozzle 12 are arranged symmetrically, and its angle is 120 ° so that paper be easier with the first drying cylinder, the second drying cylinder and Third drying cylinder is separated and be bonded, and the width for reducing paper to greatest extent moves, and makes to produce more stable, first drying cylinder 1 and the Two drying cylinders 2 are in same horizontal line, and the third drying cylinder 3 is located at immediately below it, and the first drying cylinder 1, the second drying cylinder 2 and third 3 axle center of drying cylinder constitutes equilateral triangle, is transported, is reduced by the automation paper injection that the automatic rotation of three drying cylinders realizes paper The labor intensity of worker has the extensive market demand.

Workflow: it when work, as shown in Figure 1, paper to be dried is wound on the first drying cylinder 1, then reaches first and scrapes When at knife 9, under the action of upper air nozzle 11, paper to be dried is separated with the first drying cylinder 1, and paper is transported downwards around guide roller 8 It is dynamic, it is blown on third drying cylinder 3 under the action of lower air nozzle 12, is moved around third drying cylinder 3, and when paper is wrapped in the When on three drying cylinders 3, the dry net from the first dry net deflector roll 4 and the 4th dry 7 surface of net deflector roll is covered on paper, plays protection Effect；When sheet movement is at the second scraper 10, under the action of lower air nozzle 12, paper is separated with third drying cylinder 3, at this time Dry net on paper is moved around the 4th dry net deflector roll 7, and paper then continues up, then tight under the action of upper air nozzle It is attached to the surface of the second drying cylinder 2, is taken out of by the second drying cylinder 2, drying finishes, if drying does not finish, can enter next Circulation, until drying finishes, since dry net is driven by dry net deflector roll circulation, longer life expectancy more stable compared to carrier rope, Paper web fluctuation is reduced in motion process to greatest extent, production is more stable, and paper rate of breaking is low, full-automatic operation, operation precision Height, performance are stablized, the labor intensity of worker are effectively reduced, is worthy to be popularized.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
