Abstract
The utility model relates to a belt tensioning device comprising a tension pulley (2) for adjusting the tightness of a belt (1) through a supporting moment arm (3). A pivot point (30) is arranged at the middle part of the supporting moment arm (3). One end of the supporting moment arm (3) is connected with the tension pulley (2), and the other end is a control end provided with an elasticity adjusting mechanism. The elasticity adjusting mechanism comprised a fixed seat (4), a bolt (5) and a spring (6). A through hole is arranged on the control end. The bolt (5) penetrates through the through hole at the control end and is fastened on the fixed seat (4) in a threaded way. The spring (6) is sleeved on the bolt (5) between the fixed seat (4) and the control end. Certain elasticity of the spring (6) can be maintained under the action of the bolt (5). A locking nut (7) for adjusting the elasticity of the spring (6) is arranged on the bolt (5). The belt tensioning device adopting the above structure is convenient to install, has good tensioning effect and can realize stable equipment running.
Description
Technical field
The utility model relates to a kind of belt stretcher, is specifically related to a kind of corrugated paperboard machinery that can be used for, as the belt stretcher on the transverse cutting machine.
Background technique
Present belt stretcher, the belt stretcher on the transverse cutting machine particularly, usually all be to pass through mechanical adjustment, yet restricted by installing space, comparatively difficulty of belt stretcher is installed on the transmission part of transverse cutting machine, and uses long afterwards, belt can stretch gradually, cause belt appearance shake in the running, the equipment operation instability causes quality of product defective.In addition, existing tensioning mechanism when needing to regulate rate of tension, does not have the flexible adjustment function, needs manual tune usually, and operation is very inconvenient.
Summary of the invention
The purpose of this utility model is to provide a kind of and conveniently installs, tension effects is good, the belt stretcher of stable equipment operation.
The purpose of this utility model is achieved in that a kind of belt stretcher, comprise the Idle wheel (2) of regulating belt (1) elasticity, it is characterized in that: described Idle wheel (2) supports the elasticity that the arm of force (3) is regulated belt (1) by one, the middle part of supporting the arm of force (3) is a fulcrum (30), support the arm of force (3) one ends and be connected with Idle wheel (2), it is the control end of center rotation with fulcrum (30) that the other end supports the arm of force (3) for control.
Described control end is provided with the elastic force controlling mechanism, comprise a fixed base (4), a bolt (5) and a spring (6), offer through hole on the control end, the through hole rear thread that bolt (5) passes control end is fastened on the fixed base (4), spring (6) is socketed on the bolt (5) between fixed base (4) and the control end, and under the effect of bolt (5), make spring (6) keep certain elastic force.
Described bolt (5) is provided with the locking nut (7) of Regulation spring (6) elastic force size.
Described control end is positioned at bolt (5) position and offers the grooving (31) vertical with bolt (5).
Described fulcrum (30) is for being located in a dead axle at the middle part of supporting the arm of force (3).
Good effect of the present utility model: owing to regulate the support arm of force control of the Idle wheel of belt elasticity by a band fulcrum, therefore, tension device can be located at the outside of equipment driving mechanism, not influenced by installing space.
As further improvement of the utility model, control end is provided with the elastic force controlling mechanism, under the elastic force effect of spring, can alleviate the fluctuation in the belt running, and belt is operated steadily.The elastic force controlling mechanism adopts bolt, locking nut fit adjustment, regulates very convenient.
Description of drawings
Fig. 1 is the utility model belt stretcher structural representation.
Embodiment
Below in conjunction with accompanying drawing belt stretcher embodiment of the present utility model is described in further detail.
Mode of execution: as shown in Figure 1, belt stretcher comprises the Idle wheel 2 of regulating belt 1 elasticity, Idle wheel 2 is by supporting the elasticity that the arm of force 3 is regulated belt 1, supporting the arm of force 3 one ends is connected with Idle wheel 2, the other end is a control end, the middle part of supporting the arm of force 3 is socketed on the dead axle, and as the fulcrum 30 of rotation, supporting the arm of force 3 is the center rotation with this fulcrum 30.In order to make belt stable, be provided with the elastic force controlling mechanism at control end, mainly form by fixed base 4, bolt 5 and spring 6, offer through hole on the control end, the through hole rear thread that bolt 5 passes control end is fastened on the fixed base 4, spring 6 is socketed on the bolt 5 between fixed base 4 and the control end, and under the effect of bolt 5, makes spring 6 keep certain elastic force.For convenience of the elastic force size of Regulation spring, bolt 5 is provided with the locking nut 7 of Regulation spring 6 elastic force sizes.In addition, also can be positioned at bolt 5 positions and offer the grooving 31 vertical, can reach the purpose that increases elastic force equally, realize shock-absorbing effect, make stable equipment operation with bolt 5 at control end.
Claims (5)
