Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of biodegradable film processing, in particular to a calendering device capable of preventing deviation for biodegradable film processing. Background Art
[0002] Degradable films not only have the functions and characteristics of traditional plastics, but also can be degraded in the natural environment after reaching the end of their service life through the action of microorganisms in the soil and water or through the action of ultraviolet rays in the sun, and finally re-enter the ecological environment in a reduced form and return to nature. Domestically developed varieties have covered photodegradation, photobiodegradation, photooxidative biodegradation, high starch content biodegradation, high calcium carbonate filled photooxidative degradation, and full biodegradation. When processing degradable films, a calendering device is required to stretch them.
[0003] Chinese patent CN216506322U discloses a calendering device for processing fully biodegradable film that can prevent deviation, including a bottom plate and a positioning component, support columns are installed on both sides of the top of the bottom plate, and a hydraulic rod is arranged at the top of the support column, a support frame is installed on the top of the hydraulic rod, and the positioning component for preventing the film from deviating is installed at the center bottom of the support frame, and the positioning component includes a connecting plate, a movable groove, a mobile motor, a screw, an arc plate, a connecting rod, a support block and an auxiliary roller, a movable groove is opened inside the connecting plate, and a mobile motor is installed at the right end of the movable groove, a screw is installed on the output shaft at the right end of the mobile motor, and arc plates are symmetrically arranged on the outside of both ends of the screw. The calendering device for processing fully biodegradable film that can prevent deviation is adopted by the mutual cooperation between multiple components, which can not only prevent the deviation of the fully biodegradable film during processing, but also lubricate the rotating shaft.
[0004] The working principle of the above patent states that “when in use, firstly, the driving motor 10 inside the control box 8 is started to rotate through the control panel 9, so that the driving motor 10 drives the extrusion wheel 12 arranged on the right side of the shaft 11 to rotate, and then the connecting plate 501 is driven to adjust to a suitable height through the hydraulic rod 3, so that the moving motor 503 arranged inside the connecting plate 501 drives the screw 504 to rotate, so that the screw 504 controls the movement of the externally connected curved plate 505, and then the curved plate 505 drives the connecting rod 506 to move to a suitable position, and the auxiliary roller 506 arranged on the right side of the connecting rod 506 is driven to rotate. 8. The moving position of the film entering between the extrusion wheel 12 and the lifting wheel 15 is corrected to prevent the film from deflecting and improve the processing effect of the finished product. However, since the correction function of this technical solution is to correct the film by controlling the auxiliary roller, it only corrects the deviation of one place, and the film covered by other rollers cannot be corrected. In addition, the film does not have the function of relieving the pressure of the film being pulled during the pulling process. If the film is rolled up with a large force, it is easy to cause the film to tear. In view of the above problems, a calendering device with anti-deviation for biodegradable film processing is proposed to solve the above problems. Summary of the invention

[0041] Embodiment 3
[0042] like Figure 4 , Figure 5 As shown, this embodiment provides a correction method, the limiting component includes a slide groove 15, a bidirectional motor 16, a rotating rod 17, a circulating thread 18, a slider 19 and a limiting member 20, the slide groove 15 is fixedly connected to the middle of the top of the base 1, the left and right driving ends of the bidirectional motor 16 are fixedly connected to the rotating rod 17, the outside of the rotating rod 17 is provided with a circulating thread 18, the outside of the rotating rod 17 is slidably connected to the slider 19, the inner top of the slider 19 is fixedly connected to the limiting member 20, the bidirectional motor 16 drives the rotating rod 17 to rotate, so that the limiting member 20 in the circulating thread 18 of the rotating rod 17 drives the slider 19 to slide on the outside of the rotating rod 17.
[0043] A through hole 21 is provided at the rear side of the correcting plate 14, the outer part of the active shaft 5 is slidably connected to the inner wall of the through hole 21, the outer part of the auxiliary shaft 6 is slidably connected to the inner wall of the through hole 21, a through hole 22 is provided in the middle of the correcting plate 14, the outer part of the adjusting shaft 7 is slidably connected to the inner wall of the through hole 22, a through hole 3 23 is provided in the middle of the correcting plate 14, the outer part of the round roller 12 is slidably connected to the inner wall of the through hole 3 23, the outer part of the round roller 2 13 is slidably connected to the inner wall of the through hole 3 23, and the through hole 1 21, through hole 22 and through hole 3 23 of the correcting plate 14 contact the outer surfaces of the active shaft 5, the auxiliary shaft 6, the adjusting shaft 7, the round roller 12 and the round roller 2 13 with their diameters, thereby limiting the width of the sliding film and achieving the correcting effect.
