Technical field

The utility model is related to pulp technology for making paper, more particularly to a kind of secondary limit for paper machine winding shaft Arm.

Background technology

Paper machine need to utilize winding shaft that body paper is formed rewinding, winding shaft is multiple after completing slurrying copy paper and forming body paper When rolling up body paper, longitudinal compress carries out it by a position limit arm on paper machine and limits, it is carried out using secondary position limit arm Lateral compression limit, with the increase of rewinding radius, secondary position limit arm can with the movement of winding shaft and around center rotating, when When rewinding radius reaches certain size, secondary position limit arm leads to not push down winding shaft due to length limitation, occurs running axis Phenomenon.

Utility model content

In view of the above technical problems, the purpose of this utility model is to provide a kind of secondary limit for paper machine winding shaft Arm is still ensured that when rewinding radius is larger to winding shaft by installing a telescopic extension arm additional on secondary position limit arm Transverse pressure and stable rotation, can effectively promote the body paper length of winding shaft energy rewinding.

In order to achieve the above objectives, a technical solution of the utility model use is：It provides a kind of for paper machine roll paper The secondary position limit arm of axis, including secondary limit arm body and an extension arm,

The extension arm includes：Cylinder, voussoir, connecting shaft, idler wheel and spring, the cylinder are installed by cylinder supports seat On secondary limit arm body, the voussoir is installed on the end of the piston of cylinder, is also installed on the secondary limit arm body There are voussoir support base, the planar side of the voussoir that can be slided up and down on the voussoir support base, the middle part of the connecting shaft is logical It crosses bearing to be installed on fixed supporting seat, the fixed supporting seat is installed on by bolt on secondary limit arm body, the company One end setting of spindle is positioned at the inclined-plane side of voussoir, and other end installation is there are one idler wheel, the idler wheel setting on the extension arm Higher than secondary limit arm body, one end of the spring is installed on connecting shaft on the end of voussoir side, other end installation In on cylinder supports seat.

The utility model has the beneficial effects that：By installing an extension arm additional on secondary position limit arm, make paper machine in original Still use former secondary position limit arm, when body paper rewinding radius is larger, ensure to roll paper using extension arm when paper rewinding radius is smaller The transverse pressure and stable rotation of axis can effectively promote the body paper length of winding shaft energy rewinding, reduce employee's operation shift and Tail paper number is cut, whole production cost is reduced.

Specific implementation mode

The preferred embodiment of the utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear to be made to the scope of protection of the utility model Define.

Referring to Fig. 1, the utility model embodiment includes：

A kind of secondary position limit arm for paper machine winding shaft, including secondary limit arm body 1 and an extension arm,

The extension arm includes：Cylinder 2, voussoir 4, connecting shaft 6, idler wheel 8 and spring 9, the cylinder 2 pass through cylinder supports Seat 3 is mounted on secondary limit arm body 1, and the voussoir 4 is installed on the end of the piston of cylinder 2, the secondary position limit arm sheet 1 is also equipped with voussoir support base 5 on body, and the planar side of the voussoir 4 can slide up and down on the voussoir support base 5, described The middle part of connecting shaft 6 is installed on by bearing on fixed supporting seat 7, and the fixed supporting seat 7 is installed on secondary limit by bolt On the arm body 1 of position, one end setting of the connecting shaft 6 is positioned at the inclined-plane side of voussoir 4, and there are one idler wheel 8, institutes for other end installation The setting of idler wheel 8 stated on extension arm is higher than secondary limit arm body 1, and one end of the spring 9 is installed on connecting shaft 6 close to voussoir On the end of 4 sides, the other end is installed on cylinder supports seat 3.

Fig. 2 to Fig. 5 is please referred to, the secondary position limit arm course of work of the present embodiment includes the following steps：

One, when 101 rewinding radius of body paper is smaller, winding shaft 102 is compressed by secondary limit arm body idler wheel 10, Fig. 2 is please referred to Fig. 3；

Two, become larger with the rewinding radius of body paper 101, winding shaft 102 moves on winding shaft track 103, secondary limit Arm is swung also with the movement of winding shaft 101, when reaching the limitation of length of secondary limit arm body 1, controls the work of cylinder 2 Plug stretches out, and rotary shaft 6 is rotated along the inclined-plane of voussoir 4, starts to compress winding shaft 102 by idler wheel 8, please refers to Fig. 4；
