Abstract
The utility model discloses an automatic roll changing mechanism for tensile films. The automatic roll changing mechanism comprises a rubber roll, a large arm and a gear rotation plate. One end of the large arm is provided with a groove matched with a bearing of an air bulking shaft, the large arm is connected with a first air cylinder, and the gear rotation plate is provided with a fixing device for the air bulking shaft. The automatic roll changing mechanism is characterized in that a press arm is hinged on a mounting shaft of the gear rotation plate, one end of the press arm is connected with a second air cylinder, the other end of the press arm is provided with a third air cylinder, and a pressure block is arranged on a push rod of the third air cylinder and is provided with an arc groove matched with the bearing of the air bulking shaft. The automatic roll changing mechanism for tensile films can reduce runout of the air bulking shaft during roll changing, so that flatness of film rolling is guaranteed.
Description
Technical field
The utility model relates to a kind of film automatic lap changing apparatus structure that is wound around.
Background technology
The rolling that is wound around at present film mostly adopts the mode of friction rolling, have the air-expanding shaft of paper web to be placed on the large arm of force in cover, air-expanding shaft is pressed to rubber roll surface by the large arm of force, is wound around film and passes through between paper web and rubber roll, rubber roll, in the time rotating, relies on friction force to make to be wound around film and is crimped onto on paper web.In the time that the film volume on the paper web of air-expanding shaft on the large arm of force meets the requirements of meter number, just need to carry out change of lap.Traditional coil replacing mechanism comprises gear turntable and the anchor fitting on it, anchor fitting is two match movable claw and fixed jaws, after air-expanding shaft on the large arm of force is pushed out, new air-expanding shaft drops on rubber roll and its bearing drops between movable claw and fixed jaw and be stuck, and then gear sabot is placed in new air-expanding shaft on the large arm of force with regard to turning over certain angle.But when the bearing of air-expanding shaft drops on and is stuck between movable claw and fixed jaw, because the pressure being subject to is less, therefore air-expanding shaft can produce larger beating, thereby planeness that film is curling be can not be guaranteed and affect the quality of rolling.
Summary of the invention
For the deficiencies in the prior art, problem to be solved in the utility model be to provide a kind of less in the time of change of lap the winding film automatic lap changing apparatus structure of beating of air-expanding shaft.
For this reason, the utility model is realized in the following way: a kind of film automatic lap changing apparatus structure that is wound around, comprise rubber roll, the large arm of force and gear turntable, the end of the described large arm of force is provided with the groove mating with the bearing of air-expanding shaft, the described large arm of force is connected with the first cylinder, described gear turntable is provided with the anchor fitting of air-expanding shaft, it is characterized in that: hinged pressure arm in the installation shaft of described gear biography dish, one end of described pressure arm is connected with the second cylinder, the other end is provided with the 3rd cylinder, the push rod of described the 3rd cylinder is provided with briquetting, described briquetting is provided with the arc groove mating with the bearing of described air-expanding shaft.
The end of the described large arm of force is provided with four-cylinder, and the push rod of described four-cylinder is towards groove.
In the utility model, air-expanding shaft on the surface of falling rubber roll and its bearing drop on while being stuck in anchor fitting, the second cylinder promotes one end of pressure arm, the other end that makes pressure arm is the bearing near air-expanding shaft along hinge-point, then the 3rd cylinder just drives briquetting to be pressed on the bearing of air-expanding shaft, from but air-expanding shaft be more securely fixed in rubber roll surface, less beating of air-expanding shaft, has ensured the planeness that film is curling.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
With reference to accompanying drawing, this winding film automatic lap changing apparatus structure, comprise rubber roll 10, the large arm of force 13 and gear turntable 3, wherein, one end of the described large arm of force 13 is hinged on jointed shaft 14, the other end of the described large arm of force 13 is provided with the groove 11 mating with the bearing 6 of air-expanding shaft, the described large arm of force 13 is connected with the first cylinder 1, described gear turntable 3 is provided with the registration device of air-expanding shaft, described registration device comprises movable claw 7 and fixed jaw 8, described fixed jaw 8 is fixed on gear turntable 3, described movable claw 7 is hinged on gear turntable 3, between described movable claw 7 and gear turntable 3, be provided with spring steel plate, under the effect of spring steel plate, described movable claw 7 is drawn close to fixed jaw, hinged pressure arm 9 in the installation shaft of described gear biography dish 3, one end of described pressure arm 9 is connected with the second cylinder 2, the other end is provided with the 3rd cylinder 4, the push rod of described the 3rd cylinder 4 is provided with briquetting 5, on described briquetting 5, there is the arc groove mating with the bearing 6 of air-expanding shaft, described briquetting 5 is pressed on the bearing 6 of air-expanding shaft under the driving of the 3rd cylinder 4, the end of the described large arm of force 13 is provided with four-cylinder 12, the push rod of described four-cylinder 12 is towards groove 11.
This winding film automatic lap changing apparatus structure is worked in the following way: when the film volume on the air-expanding shaft in the groove 11 of the large arm of force 13 reaches requiring of setting, the first cylinder 1 drives the large arm of force 13 to swing along jointed shaft 14, air-expanding shaft is pushed out, drop on rubber roll 10 with stylish air-expanding shaft, and the bearing 6 of air-expanding shaft is in the time falling between movable claw 7 and fixed jaw 8, the bearing 6 of air-expanding shaft flicks movable claw 7, the bearing 6 of air-expanding shaft is dropped between movable claw 7 and fixed jaw 8 completely, and be subject to the power that movable claw 7 draws close to fixed jaw 8 and be fixed between movable claw 7 and fixed jaw 8, then one end that the second cylinder 2 promotes pressure arm 9, make the other end close towards the bearing 6 of air-expanding shaft, then the 3rd cylinder 4 drives briquetting 5 to push down the bearing 6 of air-expanding shaft, then gear turntable 3 turns an angle under the driving of engine installation, after briquetting 5 and pressure arm 9 resets, make new air-expanding shaft drop on the groove 11 of the large arm of force 13 interior on, four-cylinder 12 withstands the bearing of the air-expanding shaft in groove 11 simultaneously, reduce the amplitude that air-expanding shaft is beated with rubber roll.
