Stretcher in a kind of tension control structure described herein, wherein the stretcher 8 includes a column
The main shaft 81 of structure, is respectively equipped with an extension section on 81 two sides end of main shaft, and the extension section of 81 two sides of main shaft includes using
The first extension section 82 and the second extension section 83 of least material production;Rationally with design, it is good to reply effect, registration,
It is more accurate, the higher effect of stability.
The metal shaft of corrugated paper is plugged in discoidal cover plate 1, by two pieces of friction plates installing in cover plate 1 to metal
The speed of rotation of axis is controlled, and for the fine tuning effect for improving friction plate, is realized using opening section 9.Following the description will be detailed
The detailed process of control is described.
As shown in Fig. 1 to 2, stretcher 8 is mostly installed in tension control structure, is had in lower Fig. 2 and is specifically illustrated,
The stretcher 8 includes the main shaft 81 of a column structure, and the main shaft 8 to be formed is made of metal material, which vertically pacifies
Dress forms stable support construction.
It is respectively equipped with an extension section on 81 two sides end of main shaft, the stretching structure with least effect is set, leads to
Overstretching portion guarantees the up and down motion in tension structure.
The extension section of 81 two sides of main shaft includes the first extension section 82 and the second extension section 83 using the production of least material.
Two extension sections carry out extensional motion along upper and lower two sides respectively, and then form stable stretching.
The least material that first extension section 82 and the second extension section 83 use is rubber block, polymer composite
And/or metal spring, wherein have the effect of being easily installed using rubber block, but during use, become because squeezing
Shape, rubber and high molecular material service life are not lasting enough, and are unable to satisfy the demand of high temperature friction.
Therefore setting metal spring not only meets the requirement of high temperature friction, and is not susceptible to deform.It is used improving
On the basis of service life, cost can also be controlled.
The metal spring that first extension section 82 and the second extension section 83 use is copper or steel or alloy material system
Make.According in the intensity of material and the selection of stability and price, selecting steel spring to have the low service life of price lasting
Effect.
The cross section of first extension section 82 and the second extension section 83 is in U-shaped structure that is positive or swinging to.Along first
The U-shaped bottom of extension section 82 is consolidated, and forms fixed mounting structure, while being positioned using the hatch frame at the top of it
Form the stretching and compressing effect that rebound is strong, and registration support consolidates.Wherein, the first extension section 82 and the second extension section 83
Effect is identical, but contrary, therefore is fixed along the top of the second extension section 83, install along its underpart
With buffering.
The top of main shaft 81 is arranged in first extension section 82, and the lower part of main shaft 81 is arranged in the second extension section 83, point
It is not respectively controlled along the both ends of main shaft 81, and then forms the extruding buffering of stable mounting structure and up-down structure and draw
Rebound effect when stretching.
And the vibration of friction plate can also be buffered by two extension sections, and then form the stabilization of inside configuration
Property, stability is more preferable between internal structure, improves the accuracies that opening section 9 adjusts its position.
The bottom end of first extension section 82 snaps onto 81 top of main shaft, the opening upwards of the first extension section 82, the first extension section
82 structures upwards buffer simultaneously the friction plate structure on top, stretch the position of upper friction piece, avoid its bounce.
The upper end of second extension section 83 snaps onto 81 lower part of main shaft, and Open Side Down for the second extension section 83, and similarly, second draws
83 structure of extending portion carries out buffering to the friction plate structure of lower part downwards and stretches its position, and then realizes tension controller internal junction
The stability of structure.
81 top of main shaft is equipped with the first adjusting block 86 for 82 bottom end of the first extension section of snapping, to improve main shaft 81
With the fixed effect and polarization of 82 bottom end of the first extension section, it is fixed and is fastened by the first adjusting block 86.
81 lower part of main shaft is equipped with the second adjusting block 87 for 83 upper end of the second extension section of snapping, as shown in the above,
Location and installation and fastening can be carried out to 83 upper end of the second extension section using the second adjusting block 87, and during use, it will
The middle position of main shaft 81 is set as screw-rod structure, sets nut structure for the first extension section 82 and the second extension section 83, into
And it forms nut rotation and is set on the screw rod of different location.
First adjusting block 86, the second adjusting block 87 can be set in different positions in turn by the adjusting block of adjustable position
Form adjustable fastening effect.
The top of first extension section 82 is equipped with the first installation set 84 for installing it, the bottom end of the second extension section 83
Equipped with the second installation set 85 for installing it.
During use, in order to improve the installation between friction plate upwards of the first extension section 82, setting first is pacified
Encapsulation 84 forms annulus or thimble structure, and the first installation set 84 is helped to be installed.Wherein, the first installation set 84 and the second peace
85 structure of encapsulation is identical, all has the installation effect of fastening.
In the second installation set of the bottom of the second extension section 83 setting 85 and then help 83 bottom side of the second extension section and friction plate
Between consolidate installation.
The middle position of first installation set 84 is protruding upward the first anchor point 841 used for positioning, the second installation
The middle position of set 85 is downwardly projecting the second anchor point 851 used for positioning.
During installation, setting anchor point i.e. the first anchor point 841 can be improved greatly with the second anchor point 851
To the locating effect in 85 middle position of the first installation set 84 and the second installation set, avoiding it, there is a situation where positions to be detached from, greatly
The stability improved in use.
In the specific use process, in order to avoid main shaft is supported extension section, and do not occur again while stretching
Mechanical interference causes to contact between main shaft 81 and friction plate.Therefore the setting of two ends of main shaft 81 respectively is being drawn
In the middle position of extending portion.
In the setting of specific position, the first extension section 82 is arranged in the first shaft end 81a of 81 upper end of main shaft
In inside, the second shaft end 81b of 81 lower bottom end of main shaft is arranged in the inside of the second extension section 83.Adequately avoid interference
Situation occur.
The first stretching section a, the second shaft end 81b are formed between 82 upper end the first shaft end 81a and the first extension section
The second stretching section b is formed between 83 bottom end of the second extension section.
The space size in two stretching sections is followed by the position change of the first adjusting block 86 or the second adjusting block 87 and sends out
It is raw to change, there is modulability can adequately realize 8 inside stress balance of stretcher, the stability in use process further adds
By force.
