Abstract
The utility model relates to a paper machine coating portion seasoning cylinder dry net tensioning mechanism. The paper machine coating portion seasoning cylinder dry net tensioning mechanism is characterized in that a lead screw tensioning mechanism is arranged on a rack below a paper machine coating portion coating guide roll, the lead screw tensioning mechanism is composed of an operation side lead screw lifting machine, a middle connecting rod and a transmission side lead screw lifting machine, the lower end of the transmission side lead screw lifting machine is fixed to a support, and the support is hinged to a hinge support through a lower pin shaft. The lead screw lifting machine is used as a tensioning mechanism, through the self-locking function of the mechanism, a dry net is kept in a tensioned state after being tensioned, meanwhile, the connecting rod is arranged between the operation side lead screw lifting machine and the transmission side lead screw lifting machine, the two sides of a tensioning device are kept synchronous in the lifting process, the tension degrees of the two sides of the guide roll of the dry net are kept consistent, the height of the roll face of the guide roll of the dry net is identical, and therefore the function of the air cylinder tensioning device is achieved, the operation is stable and reliable, the production problem of off tracking and bending of the dry net is effectively solved, and good economic benefits are obtained.
Description
Technical field
The utility model relates to the papermaking equipment technical field, particularly relates to a kind of paper machine coating part debugging mode cylinder strainer.
Background technology
The dry net tensioning apparatus of paper machine coating part debugging mode cylinder one all uses the cylinder tensioning apparatus always, as shown in Figure 1, this mechanism will be coated with dry net application guide after stretching out by atmospheric control control cylinder bar to lift, make dry Wondertek to the necessary tensioning degree of production run, after dry net tensioning, atmospheric control comprises that cylinder must reliable operation make dry net remain this duty simultaneously.But in actual production process, often occur due to gas circuit catastrophic failure or cylinder pressure release cause after dry net sideslip giving a discount damage under the accident of machine.Cause non-programmed halt, bring very large direct economic loss and indirect economic loss to company's production and operation.
Summary of the invention
The purpose of this utility model just is to overcome the defect of above-mentioned prior art, and a kind of stable performance is provided, and preventing after dry net sideslip gives a discount damages and cause the dry net strainer of paper machine coating part debugging mode cylinder of shutting down.
The utility model is achieved through the following technical solutions:
The dry net strainer of a kind of paper machine coating part debugging mode cylinder, it is characterized in that: the frame below paper machine coating part application guide is installed the leading screw strainer, described leading screw strainer is comprised of fore side screw-threaded shaft elevator, intermediate connecting rod and transmission side screw-threaded shaft elevator, described transmission side screw-threaded shaft elevator lower end is fixed on bearing, and this bearing is hinged on hinged-support by lower bearing pin.
Described leading screw strainer is fixed on leading screw and connects on spindle nose, and this leading screw connects spindle nose and is fixed on frame by bearing pin.
The utility model adopts screw-threaded shaft elevator as strainer, the auto-lock function that utilizes this mechanism itself to have, make to keep tensioning state after dry net tensioning, simultaneously, design connecting rod between transmission side and fore side screw-threaded shaft elevator, guarantee that tensioning apparatus both sides in lifting process keep synchronous, the tensioning degree of dry net deflector roll both sides is consistent, after tensioning, dry net deflector roll roll surface height is identical, thereby the function that has possessed the cylinder tensioning apparatus, and stable and reliable operation, effectively solved dry net sideslip this production problem that gives a discount, and obtained good economic benefit.
The accompanying drawing explanation
The structural representation sketch that Fig. 1 is the dry net strainer of prior art paper machine coating part debugging mode cylinder;
The structural representation sketch that Fig. 2 is the dry net strainer of the utility model paper machine coating part debugging mode cylinder;
The schematic diagram that Fig. 3 is the screw-threaded shaft elevator structure.
The specific embodiment
The dry net strainer of paper machine coating part debugging mode cylinder of the present utility model is to make original cylinder 12 tensioning apparatus into the leading screw strainer, be specially: pass through upper pin 3 on the frame 2 below the application guide 1 at paper machine coating part debugging mode cylinder place, be arranged on leading screw connection spindle nose 4 on bearing pin 3 and be connected and installed the leading screw strainer, this leading screw strainer is by fore side screw-threaded shaft elevator 8, intermediate connecting rod 9 and transmission side screw-threaded shaft elevator 10 form, transmission side screw-threaded shaft elevator 10 lower ends are arranged on bearing 5, bearing 5 is hinged on hinged-support 7 by lower bearing pin 6, hinged-support 7 is fixedly mounted on base 11.
