Description
Technical field: the utility model relates to the speed of a kind of thin film extruding production line and tire equipment extruding production line and regulates float roller device, relate in particular to a kind of extruding production line automatic heat-transfer type constant tension speed adjustment floating roller device, belong to the rubber and plastics machine technical field.
Background technology: at present, the speed of domestic rubber and plastics machine extruding production line is regulated the speed regulation function that float roller device only has the front-and-back-end functions section, lacks and passs greatest service energy and constant-tension control function automatically, goods is passed a common employing manually pass a mode; Not only difficult quality guarantee, efficient are low, but also have bigger potential safety hazard; In addition, the tension force of goods is also uncontrollable, causes goods to draw high easily or the unequal many mass defect of tension force.
Summary of the invention: in order to overcome the deficiencies in the prior art, the utility model aims to provide a kind of automatic heat-transfer type constant tension speed adjustment floating roller device.
To achieve these goals, the utility model by the following technical solutions: it comprises the power transmission shaft that is bearing on the support, is fixed on dancer on this power transmission shaft by linking arm; Be provided with the power transmission shaft of position sensor and connect, be provided with in the frame and pass head unit and tension balance device with connecting axle on being bearing in frame; Described pass head unit by be fixed on gear on the connecting axle, be fixed on finger on this gear, be installed in the pivoted arm on the connecting axle, a cylinder of passing that is connected with this pivoted arm constitutes, described tension balance device constitutes with the tooth bar of gears engaged, the tension adjustment cylinder that is connected with this tooth bar by being located in the frame; Frame is provided with positioner, this positioner by be fixed on location-plate on the frame, be located at the annular sliding shoe in this location-plate annular groove, the rotor plate that is fixed on the connecting axle constitutes; The weight linear meter that is fixed with balancing weight is fixed on the connecting axle by the tensioner cover.
The bottom surface of tooth bar is provided with the guide bearing that is installed in the frame; Balancing weight is the multiple combined-type structure.
Compared with the prior art, the utility model has been owing to adopted technique scheme, therefore not only realized goods pass automatically the greatest service can, eliminated potential safety hazard, improved production efficiency; And under situation, can keep the constant-tension of goods to the rapid adjusting of functional section speed before and after the extruding production line, improved Products Quality.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the right view of Fig. 1;
Fig. 3 is the A-A cutaway view among Fig. 1.
Among the figure: dancer 1 linking arm 2 position sensors 3 shaft couplings 4 frames 5 are passed a cylinder 6 pivoted arms 7 gears 8 balancing weights 9 weight linear meters 10 rotor plates 11 connecting axles 12 tensioners and are overlapped 13 location-plates, 14 sliding shoes, 15 guide bearings, 16 tooth bars, 17 tension adjustment cylinders, 18 power transmission shafts, 19 supports, 20 fingers 21
The specific embodiment: the utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
In Fig. 1～3, on support 20, dancer 1 is fixed on this power transmission shaft by linking arm 2 power transmission shaft 19 that is fixed with position sensor 3 by bearing block support, and the connecting axle 12 that is bearing on the frame 5 connects with power transmission shaft 19 by shaft coupling 4.Be provided with in the frame 5 and pass head unit and tension balance device, the described head unit of passing is by being fixed on gear 8 on the connecting axle 12, being fixed on finger 21 on this gear, being installed in pivoted arm 7 on the connecting axle 12, being fixed in the frame 5 and constituting with the hinged cylinder 6 of passing of this pivoted arm by bearing, and described tension balance device constitutes with the tooth bar 17 of gear 8 engagements, the tension adjustment cylinder 18 that is connected with this tooth bar by being located in the frame 5.Frame 5 is provided with positioner, this positioner by be fixed on the back side on frame 5 wallboards be provided with annular groove location-plate 14, be located at the annular sliding shoe 15 in this annular groove, the rotor plate 11 that is fixed on the connecting axle 12 constitutes.Weight linear meter 10 is fixed on connecting axle 12 terminations by tensioner cover 13, is fixed with balancing weight 9 at the end near this weight linear meter.In order to improve the kinematic accuracy of tooth bar 17, be provided with two guide bearings 16 that are installed in the frame 5 in the bottom surface of tooth bar 17.For the ease of regulating the weight of balancing weight 9, this balancing weight combines by some.
During work, when extruded product arrives before this device, pass a cylinder 6 and stretch out and promotes pivoted arm 7 and rotate, this pivoted arm rotates by finger 21 driven gears 8, and this gear is return by tooth bar 17 promotion tension adjustment cylinders 18; Meanwhile gear 8 passes motion to power transmission shaft 19 and turns to extreme lower position by linking arm 2 drive dancers 1 around this power transmission shaft by connecting axle 12 and contacts with goods, the position that keeps tension adjustment cylinder 18, return and pass a cylinder 6, thereby realize passing automatically the greatest service energy.After the head work of passing is automatically finished, because goods are inconsistent in the speed of front and back functional section, this moment, position sensor 3 was in the maximum displacement state, its deviant can with extrude line traffic control stroke interlock and impel speeding up of back-end function section, thereby make dancer 1 passive lifting; When the dancer 1 passive tension force that lifts during greater than the ratio adjusting valve setting pressure, tension adjustment cylinder 18 is forced to retreat, position sensor 3 sends signal forces the speed of back-end function section to reduce, thereby at the constant tension of realizing having kept when front-and-back-end functions section speed is regulated 1 pair of goods of dancer.The position of rotor plate 11 can be determined in the position of sliding shoe 15, thus the angle of control dancer 1 swing.Adjusting the quantity of balancing weight 9 and the position on weight linear meter 10 can balance dancer 1 and the gravity of linking arm 2, thereby can guarantee to keep constant at the tension force that dancer 1 contacts with goods.
