Abstract

The utility model discloses drying groups of the paper making machine driven by guide rolls, which are mainly used for the drying of the paper web which is squeezed and dewatered. The prior art adopts a gear wheel which can operate through transmitting the drying cylinder groups, the drying cylinder groups can drag a dry net or a dry blanket, and thus, the paper web can normally operate. The utility model adopts one or more driving guide rolls which are driven by a direct current motor to drive the dry net or the dry blanket which can drag the drying cylinder groups to operate, and accordingly, the purpose of transmitting the operation of the paper web can be obtained. The utility model provides two structures of an upper-layer drying cylinder group and a lower-layer drying cylinder group which are driven by the guide rolls.

Description

Drying groups of paper making machine driven by guide roll

The utility model relates to a kind of paper machine dryer group that drives with deflector roll, be mainly used in the oven dry of the paper web behind the press dewatering, it is to adopt one or more driving deflector rolls that driven by direct current generator to drive dried net or dryer felt, drag the cylinder group running by dried net or dryer felt again, thereby reach the purpose of transmitting the paper web operation.

Prior art is to adopt the running of gear transmission cylinder group, drags dried net or dryer felt by cylinder group again, drives paper web and moves together.Its weak point is that cylinder group need dispose more high class gear and gear lubrication system, makes body huge, and equipment investment is big, operation noise height, inconvenient maintenance.

The purpose of this utility model is to provide a kind of and makes the frame that initiatively transmission replaces high class gear power train and complexity with deflector roll, and the paper machine dryer group with the deflector roll driving simple and compact for structure, easy to maintenance, that operating noise is little.

The utility model is achieved through the following technical solutions.The utility model is that one or more driving deflector rolls that driven by direct current generator are set in one group of cylinder group, drive dried net or dryer felt by driving deflector roll, drag the cylinder group running by dried net or dryer felt again, and under the drive of doing net, reach the purpose of transmitting the paper web operation.

Embodiment of the present utility model, can pass through Fig. 1, Fig. 2 and describe in detail:

Fig. 1 is the structural representation of first embodiment of the utility model:

Fig. 2 is the structural representation of second embodiment of the utility model:

In Fig. 1, by the cylinder group that two rows drying cylinder 5 is formed, dried net 1 and a series of dried net deflector rolls 2 etc. are formed dried net circle road.Present embodiment is in two dried net circle roads a driving deflector roll 4 to be set respectively up and down, drives dried net 1 by driving deflector roll 4 and moves, and dragging one by dried net 1 again is routine drying cylinder 5 runnings.

In the cylinder group as shown in Figure 2, by drying cylinder 5 and drag drying cylinder 5 ', dried net 1 and is that routine dried net deflector roll 2 etc. is formed and done net and enclose the road.Present embodiment is provided with a driving deflector roll 4 in a dried net circle road therein, drive dried net 1 operation by driving deflector roll 4, drag a series of dried net deflector rolls 2, drying cylinder 5 and 10 runnings of baking blanket cylinder by dried net 1 again, be fixed in gear 9 transmissions on the drying cylinder 5 be fixed in drag drying cylinder 5 ' on gear 9, and by drag drying cylinder 5 ' and dried net 1 drive other drying cylinder 5 and 10 runnings of baking blanket cylinder in the same dried net circle road.

In Fig. 1 and Fig. 2, paper web 7 enters cylinder group through paper feeding deflector roll 6, and the paper web 7 after the oven dry is through 8 outputs of paper delivery deflector roll.Drive deflector roll 4 places at each, an auxiliary carrying roller 3 is set pushes down dried net 1,, increase drawing force, make more stable transmission to increase dried net 1 and the cornerite that drives deflector roll 4.

Compared with the prior art, the advantage such as the utlity model has does not need high class gear transmission system and complicated frame, and simple in structure, and operating noise is little, and equipment investment is few can be used for various paper machine dryer groups.

Claims

1, a kind of by doing net circle road, drying cylinder and dragging the paper machine dryer group that drying cylinder is formed, it is characterized in that at least one was driven and driven dried net 1 operation by direct current generator driving deflector roll 4 is set in doing net circle road, and drag the cylinder group running by dried net 1.

2, paper machine dryer group according to claim 1 is characterized in that being provided with at least one and drives deflector roll 4 in the whole dried net circle road of cylinder group, and by be fixed on the drying cylinder 59 transmissions of a pair of gear other drag drying cylinder 5 ' and drying cylinder 5 runnings.

3, paper machine dryer group according to claim 1 is characterized in that driving deflector roll 4 places at each, has one to push down the carrying roller 3 of doing net, to increase dried net 1 and the cornerite that drives deflector roll 4.
