The tensioning control apparatus
Technical field
The utility model relates to a kind of tensioning control apparatus, and the material that can carry by balance weight mechanism tensioning adaptively of this control apparatus belongs to mechanical manufacturing field particularly.
Background technology
In the rubber tire course of processing, need heel fabric is separated with lining cloth according to technological requirement, heel fabric directly is delivered on the feed frame and is fitted with other sizing materials then.In being delivered to the process of feed frame, require heel fabric to have certain degree of tension and delivery speed, to satisfy the requirement of attaching process.
From improving the angle of crudy, when the degree of tension of rim of the mouth infantees and delivery speed change and when having influence on normal applying operation, tightening device should carry out self adaptation to be regulated, or sends signal with the controlling and driving motor by detecting device.But the unexposed in the prior art tightening device that this type of can self adaptation be regulated.
The utility model content
Tensioning control apparatus described in the utility model, be to address the above problem and material passes to be transported on the feed frame from the dancer below that is connected with balance weight mechanism, can regulate the rising and the decline of dancer by dynamical equilibrium between balance weight mechanism and the dancer, and then realize regulating the formed storage pocket of material size, prevent that material from excessively stretching and accumulation.
Design goal of the present utility model is that degree of tension and delivery speed after employing requires the setting material to lead out according to attaching process in the course of conveying realize the self adaptation regulative mode, avoid occurring windrow and material extrusion, raising applying quality.
For realizing above-mentioned design goal, described tensioning control apparatus mainly has:
A plate, this connecting panel is connected with the material unwinding equipment;
One framework, this framework top connects described connecting panel, is provided with several backgauge rollers below connecting panel, is provided with the vertical axis of guide in the framework both sides;
One dancer, this dancer is set between the axis of guide versatilely;
One balance weight mechanism, this balance weight mechanism is installed on the framework, comprises one by steel rope bonded assembly counter weight, and the other end of steel wire rope is connected on the axle of dancer, and steel wire loop is connected between the upper and lower roller.
As the tensioning control apparatus of above-mentioned scheme, material causes dancer downwards and passes, is transported on the feed frame from the below of dancer from the backgauge roller.
Keep a kind of dynamically balance with dancer bonded assembly counter weight and dancer, when material passes below dancer, the degree of tension of material and delivery speed directly are reflected on the balance weight mechanism, rising by dancer and descend and regulate material and pass the formed storage pocket of dancer size, thus realize the effect that prevents that material from stretching and piling up.
Further improvement project is, described dancer is set between the axis of guide of both sides by mount pad, linear bearing in the mount pad directly is socketed on the axis of guide, and the described dancer mount pad of steel wire penetrating is connected on the steel rope after the axle of dancer runs through mount pad.
Dancer adopts the linear bearing guiding, and dancer and counter weight are connected in balance weight mechanism by steel rope closed loop ground, and balance weight mechanism passes through counter weight, makes dancer be in dynamic balance state.When the storage pocket pulling force of material formation changes, can make positive response.
For making dancer, passing the sheathed hollow bolt of steel rope upper and lower end difference of dancer mount pad by between the axis of guide of both sides, sliding up and down smoothly.
By regulating the spacing of hollow bolt and steel rope, can regulate the degree of tension of steel rope itself, and prevent the swing of counter weight, make that dancer can upper and lower smooth motion.
As above content, the advantage of described tensioning control apparatus is, when material passes from the dancer below, the degree of tension of material and delivery speed can be controlled and regulate by balance weight mechanism, and the dynamical equilibrium of balance weight mechanism itself and degree of tension also can be regulated, realize a kind of self adaptation adjusting, avoided occurring windrow and material extrusion effectively.

Fig. 2 is the side direction structural representation of Fig. 1;
Fig. 3 is the structural representation of described balance weight mechanism;
As shown in Figure 1 to Figure 3, connecting panel 1, framework 2, backgauge roller 3, the axis of guide 4, dancer 5, axle 51, mount pad 52, linear bearing 53, hollow bolt 54; Balance weight mechanism 6, steel rope 61, counter weight 62, roller 63, and pallet 7.
The specific embodiment
Embodiment 1, and as shown in Figure 1 to Figure 3, described tensioning control apparatus is connected with the material unwinding equipment by connecting panel 1.
Framework 2 tops are connecting connecting panel 1, below connecting panel 1, be provided with several backgauge rollers 3, be provided with the vertical axis of guide 4 in framework 2 both sides, dancer 5 is set between the both sides axis of guide 4 by mount pad 52, and the linear bearing 53 in the mount pad 52 directly is socketed on the axis of guide 4.
The steel rope 61 of balance weight mechanism 6 passes mount pad 52, is connected on the steel rope 61 after the axle 51 of dancer 5 runs through mount pad 52.
Balance weight mechanism 6 is installed on the framework 2, and its steel rope 61 is connecting on the axle 51 of counter weight 62 and dancer, and steel rope 61 is socketed between the upper and lower roller 63.
Dancer 5 adopts linear bearings 53 guiding, and dancer 5 and counter weight 62 are connected in balance weight mechanism 6 by steel rope 61 closed loops ground, and balance weight mechanism 6 passes through counter weight 62, makes dancer 5 be in dynamic balance state.
The sheathed hollow bolt 54 of upper and lower end difference at the steel rope 61 that passes dancer mount pad 52.
In actual use, can on the axis of guide 4 of framework 2 midways location, several proximity transducers be set, by detecting the speed of leading out that the formed storage pocket of material position and size are regulated material.
When the storage pocket was excessive, the sensor of extreme lower position can send detected signal to control system, and control system is led out speed by adjusting diminishes the storage pocket.
When the storage pocket was too small, the sensor of extreme higher position can send detected signal to control system, and control system is led out speed by adjusting makes the storage pocket become big thereupon.
