Description
Technical field
Metal working technical area is the utility model is related to, more particularly to a kind of tensioner for preventing plowing from band.
Background technology
Metal needs to be stretched before cut-out operation is carried out, so will use tensioner at Working position drawing.
Tensioner is generally adopted by a pair of cylindrical rubber tires to provide tension force, i.e. two rubber tire jam-packed bands, then rolls and carries out
Conveying, the inside of rubber tire must be metal material, and outside will use flexible material.But when rolling, rubber tire
Interior outside easily skid, the changing of the relative positions easily occurs on the outside of rubber tire between band, then the metal fillings on band may scratch band
Material surface, cause band outward appearance unqualified.
Therefore, it is necessary to a kind of new tension machine is provided to solve the above problems.
Utility model content
Main purpose of the present utility model is to provide a kind of tensioner for preventing plowing from band.
The utility model is achieved through the following technical solutions above-mentioned purpose：A kind of tensioner, including frame and activity are set
The upper compressed part and lower compressed part being placed in frame, upper compressed part and lower compressed part can be close to each other；The upper compressed part includes
What cooler bin opposite side was fixed in cooler bin, the drive roll for being articulated in cooler bin side, activity packs tightly block, around drive roll and bag
Belt on the outside of tight block and the friction plate located at cooler bin bottom, the friction plate contact belt hypomere, and the block that packs tightly is in
Circular arc and the trend for always having remote cooler bin；The upper compressed part and lower compressed part structure are symmetrical above and below.
Specifically, the coefficient of kinetic friction between the friction plate and belt is less than the static friction system between belt and band
Number.
Specifically, the frame includes pedestal, two columns being erected on pedestal and the company for connecting each pair column top
Connect beam；The tie-beam is provided with down pressing oil cylinder, the upper compressed part lifting of down pressing oil cylinder driving；The lower compressed part is fixed on pedestal
Top.
Further, the upper compressed part also includes the sliding part positioned at both sides, and the lifting of the sliding part is limited to two
The column of side.
Further, the upper compressed part also includes the rotating beam being connected between sliding part, and the cooler bin is placed on rotation
Turn outside beam.
Using above-mentioned technical proposal, the beneficial effect of technical solutions of the utility model is：
1st, the structure of the utility model compressed part makes belt remain tensioned state, and ensures belt and band during compression
Do not relatively move, avoid strip surface from scratching.
2nd, cooler bin cools to the frictional heat in transmission process.
3rd, the kinetic force of friction between friction plate and belt must be significantly less than the stiction ability between belt and band
Ensure not scratch band.
4th, column not only plays support connection beam action, moreover it is possible to as the track of limit slippage portion motion, makes compression
The up and down balance system in portion, warpage is not produced when being clamped band.

Embodiment
The utility model is described in further detail with reference to specific embodiment.
Embodiment：
As shown in Figure 1 to Figure 3, a kind of tensioner of the present utility model, including frame 1 and be movably set in frame 1
Upper compressed part 2a and lower compressed part 2b, upper compressed part 2a and lower compressed part 2b structures it is symmetrical above and below and can be close to each other.Work
Before, away from each other, band 3 just passes through between upper compressed part 2a and lower compressed part 2b, so by upper compressed part 2a and lower compressed part 2b
Upper compressed part 2a and lower compressed part 2b is adjacent to each other afterwards, a part for band 3 is clamped, such work in-process of band 3 can just be protected
Maintain an equal level whole state.
As depicted in figs. 1 and 2, frame 1 includes pedestal 11, two columns 12 being erected on pedestal 11 and connected often to oppose
The tie-beam 13 on the top of post 12；Tie-beam 13 is provided with down pressing oil cylinder 131, the upper compressed part 2a liftings of the driving of down pressing oil cylinder 131；Under
Compressed part 2b is fixed on the top of pedestal 11.During work, lower compressed part 2b is remained stationary as, the upper compressed part 2a of the driving of down pressing oil cylinder 131
Push and band 3 is clamped between upper compressed part 2a and lower compressed part 2b, then band 3 is in upper compressed part 2a and lower compressed part
Conveyed forward under 2b collective effect.
As depicted in figs. 1 and 2, upper compressed part 2a includes the sliding part 21 positioned at both sides, and the lifting of sliding part 21 is limited to
The column 12 of both sides.Column 12 not only plays a part of supporting tie-beam 13, moreover it is possible to the track moved as limit slippage portion 21,
Make compressed part 2a up and down balance system, warpage is not produced when being clamped band 3.
As shown in figure 3, upper compressed part 2a also includes being connected to rotating beam 22 between sliding part 21, is placed on outside rotating beam 22
Cooler bin 23, be articulated in the side of cooler bin 23 drive roll 24, activity be fixed on the opposite side of cooler bin 23 pack tightly block 25, around
Cross drive roll 24 and pack tightly the belt 26 in the outside of block 25 and the friction plate 27 located at the bottom of cooler bin 23, friction plate 27 contacts skin
The hypomere of band 26.Because lower compressed part 2b and upper compressed part 2a symmetrical configurations, therefore repeat no more.Drive roll 24 provides belt 26 and passed
Dynamic power, pack tightly block 25 in circular arc and always have the trend of remote cooler bin 23, this can make belt 26 tighten and by active
The transmission of roller 24., when upper compressed part 2a contacts band 3, the meeting of belt 26 by reaction force because relaxed, but pack tightly block for this
25 can compensate this relaxation, it is ensured that belt 26 is driven.Friction plate 27 makes the raised plane of the hypomere of belt 26 and goes to contact band
Material 3, friction plate 27 is actually that a kind of material of coefficient of friction very little is made, so friction plate 27 bestows band through belt 26
During 3 pressure, the both sides of belt 26 respectively produce a frictional force.Because preventing from producing injury to the surface of band 3, belt 26 is not
Energy opposing webs 3 slide, if static friction that is, between belt 26 and band 3, belt 26 are bound to mutually slide with friction plate 27,
So must be dynamic friction.In the case where the pressure at both sides of belt 26 is essentially identical, dynamic between friction plate 27 and belt 26 rubs
The confficient of static friction that wiping coefficient must be significantly less than between belt 26 and band 3, which just can ensure that, does not scratch band 3.Cooler bin 23 is right
Frictional heat in transmission process is cooled.
Above-described is only some embodiments of the present utility model.For the person of ordinary skill of the art,
On the premise of not departing from the utility model and creating design, various modifications and improvements can be made, these belong to this practicality
New protection domain.
