Abstract
The utility model relates to a dry compound machine, in particular to a tension system of the dry compound machine. The tension system of the dry compound machine comprises a guide roll and a floating roll, wherein the guide roll is installed on a rotation shaft, swing arms are respectively arranged at two ends of the rotation shaft, two ends of the floating roll are respectively and fixedly arranged on the swing arms, a gear is installed on the rotation shaft, the gear is meshed with another gear, the another gear is connected with a potentiometer, the potentiometer is connected with a frequency changer, the frequency changer is connected with a control center, an air cylinder is connected with one end of each swing arm, close to the floating roll, and the air cylinders are connected with the control center. When a swing angle of the floating roll is small, a user can adjust tension of a film by directly changing pressure of the air cylinders, but when the tension is changed during the winding process, the floating roll correspondingly swings, and the potentiometer indirectly detects tension changes, and controls winding speed after adjusted by the control center so as to keep the tension of the film constant.
Description
Technical field
The utility model relates to dry compound machine, is the tension system of dry compound machine specifically.
Background technology
In the production and processing of coiled material, as the printing of rolling film or paper etc., be coated with, unreel, rolling etc. is about batching the operation of operation, coiled material tension force is dynamically changing.Change batching the diameter of reel in operational sequence, this variation can cause the variation of coiled material tension force: coiled material as too small in tension force, can relax wrinkling; Overtension, can cause coiled material stretching transition, even can make to roll up structure distortion fracture.In actual production, the characteristic of tension variation, reel-motor and actuating device that when the principal element that affects tension force control has mechanical wear, the acceleration and deceleration of film stretching spring rate, film volume inertia causes etc.Therefore be, very necessary for ensureing that the surface quality of production efficiency and coiled material keeps constant tension force.
Utility model content
For above-mentioned technical matters, the utility model provides a kind of tension system that leads the dry compound machine that can keep constant-tension.
The utility model solves the problems of the technologies described above adopted technical scheme: the tension system of dry compound machine, comprise a guiding roller and a dancer, guiding roller is installed in rotating shaft, these rotating shaft two ends are respectively arranged with swing arm, and described dancer two ends are fixedly arranged on respectively in described swing arm, and a gear is installed in rotating shaft, this gear engages with another gear, described another gear is connected with potential device, and potential device is connected with frequency converter, and frequency converter is connected with control center; Be connected with cylinder in swing arm near one end of dancer, cylinder is connected with described control center.
As preferably, the admission port of described cylinder is connected with pressure regulating valve, and this pressure regulating valve is connected with control center.
As preferably, the air extractor duct of described cylinder is connected with flow regulating valve, and this flow regulating valve is connected with control center.
As preferably, on described flow regulating valve, be connected with silencer.
As can be known from the above technical solutions, when dancer pivot angle hour, the pressure that can directly change cylinder just can be adjusted the tension force of film; But in winding process, in the time that tension force changes, the corresponding swing of dancer, potential device indirect detection goes out tension variation, after control center adjusts, controls coiling speed, to keep memberane stress constant.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the connection diagram of cylinder in the utility model.
Detailed description of the invention
Introduce in detail the tension system of dry compound machine of the present utility model below in conjunction with Fig. 1, Fig. 2, it comprises a guiding roller 1 and a dancer 2, guiding roller is installed in rotating shaft 3, these rotating shaft two ends are respectively arranged with swing arm 4, and described dancer two ends are fixedly arranged on respectively in described swing arm, and a gear 5 is installed in rotating shaft, this gear engages with another gear 6, described another gear is connected with potential device 7, and potential device is connected with frequency converter 8, and frequency converter is connected with control center 9; Be connected with cylinder 10 in swing arm near one end of dancer, cylinder is connected with described control center.In the time of cylinder access pressurized air, act on tension force on film less, dancer pivot angle is less, and the pressure that can directly change cylinder by control center just can be adjusted the tension force of film; In winding process. in the time that tension force changes, the corresponding swing of dancer, thereby cause rotating shaft rotation, rotating shaft is sent to potential device by the gear of pair of meshing by rotational angle, potential device indirect detection goes out tension variation, and signal is passed to frequency converter by potential device, and after control center adjusts, control coiling speed, keep memberane stress constant.In the utility model, control center is prior art.
As preferably, the admission port of described cylinder is connected with pressure regulating valve 11, and this pressure regulating valve is connected with control center; The air extractor duct of cylinder is connected with flow regulating valve 12, and this flow regulating valve is connected with control center; On flow regulating valve, be also connected with silencer 13.In implementation process, the air extractor duct of cylinder is installed flow regulating valve, can control exhaust velocity by it, makes cylinder have a back pressure, prevents cylinder moving excessive velocities and produces impact.When use, flow regulating valve should be adjusted to correct position, and the sensitivity pressure regulating valve of taking into account tension force detection is arranged on the admission port of cylinder, and it preferably adopts precise pressure regulating valve, the precise pressure regulating valve precision of voltage regulation is high, can reduce the fluctuation of admission port gaseous tension and cause that beating of dancer causes the variation of tension force.Meanwhile, on flow regulating valve, be also connected with silencer, to reduce noise.
Above-mentioned embodiment is only for illustration of the utility model, and be not to restriction of the present utility model, the those of ordinary skill in relevant technologies field, in the situation that not departing from the utility model spirit and scope, can also make various variations and modification, therefore all technical schemes that are equal to also should belong to category of the present utility model.
