Description

Technical Field

[0001] The invention relates to the technical field of film processing detection, in particular to an anti-wrinkle plastic film flattening detection device. Background Art

[0002] Plastic film is made of polyvinyl chloride and other resins. When producing and preparing plastic film, it is necessary to flatten the plastic film so that the plastic film can be used normally and effectively. However, after the flattening operation of the plastic film is completed, the flatness of the flattened plastic film needs to be tested.

[0003] The existing patent document with announcement number CN116878425A discloses a wrinkle-proof plastic film flattening detection device, including a workbench, a detection structure is arranged on the surface of the workbench, and the detection structure includes two first pressing plates, the two first pressing plates are respectively fixedly connected to the surface of the workbench, and the sides of the surfaces of the two first pressing plates close to each other are rotatably connected to the same first reel, and a plastic film is wound on the arc surface of the first reel; two second pressing plates are fixedly connected to the surface of the workbench, and the sides of the surfaces of the two second pressing plates close to each other are rotatably connected to the same second reel, and the plastic film is wound on the arc surface of the second reel. When testing the plastic film, it will be more convenient and quick, and it is not easy to wrinkle or break. The flatness test of the plastic film can be more intuitive and clear, thereby improving the accuracy and reliability of the test results; when testing the flatness of the plastic film, it is not easy for the plastic film to tilt due to the increase and decrease of the plastic films wound on the first reel and the second reel, thereby affecting the accuracy of the plastic film test, thereby further improving the accuracy and reliability of the test results, and improving the use effect of the test structure; the plastic film is not easy to deviate when it is rolled up, thereby not easy to cause wrinkles in the plastic film, making the rolling of the plastic film smoother and neater, and making the plastic film less likely to wrinkle during the test, thereby better testing the flatness and improving the accuracy of the test results.

[0004] Although the above-mentioned anti-wrinkle plastic film flattening detection device can solve the corresponding technical problems, during the detection process, the two sides of the plastic film are blocked and limited by the protective plate device. However, the positions of the two baffles are fixed and unchanged, which has usage limitations. As a result, when producing plastic films of different widths, different types of protective plate devices need to be prepared for replacement. At the same time, when loading and unloading the plastic film roll on the second reel, the protective plate device needs to be removed first, and then the protective plate device needs to be assembled when the film is tested, which not only increases the use cost of the device, but also increases the labor intensity of the staff. For this reason, we propose an anti-wrinkle plastic film flattening detection device. Summary of the invention

The second fixed plate 332 is driven by the displacement mechanism 8 to move horizontally, so that the rectangular block 335 can be stuck in or disengaged from the rectangular groove 334, so as to realize the positioning or unlocking of the unwinding roller 31 and the winding roller 32. When the rectangular block 335 is stuck in the inner cavity of the corresponding rectangular groove 334, it can further play an auxiliary supporting role for one end of the unwinding roller 31 or the winding roller 32, which helps to improve the stability of the unwinding roller 31 and the winding roller 32 during rotation; when the rectangular block 335 is disengaged from the inner cavity of the corresponding rectangular groove 334, the unwinding roller 31 or the winding roller 32 can be unlocked, so as to facilitate the subsequent loading and unloading operations of the film roll on the unwinding roller 31 or the winding roller 32.

The surface of the second support plate 61 is provided with a second sliding hole 66 for the connecting rod 65 to pass through. The connecting rod One end of 65 away from the screw sleeve 64 movably penetrates into the inner cavity of the first through hole 54 and is fixedly connected to one side of the corresponding slider 55.

The two ends of the surface of the connecting rod 65 are slidably connected to the inner wall surfaces of the second sliding hole 66 and the first sliding hole 57 respectively. By rotating the stud 63, the upper roller 53 can be driven to move up and down along the axial direction of the guide column 56 under the action of the thread, and then the distance between the lower roller 52 and the upper roller 53 can be adjusted according to the thickness of the film, so as to improve the application range of the device and avoid the existence of usage limitations.

[0070] like Figure 6 As shown, the top end of the stud 63 movably penetrates to the top of the second support plate 61 and is fixedly connected to the first knob 67 . The surface of the stud 63 is rotatably connected to the penetration point of the second support plate 61 through a bearing, and the stud 63 is conveniently rotated by the first knob 67 .

[0071] A controller is also installed on the workbench 11.

The controller is used to adjust the working status or parameters of the laser displacement sensor 22, CCD camera 23, fill light 24, rodless cylinder 25, laser engraving machine 26, pulley 42 and electric telescopic rod 81. The controller can use a PLC controller with model CPM1A-10CDR-A-V1. The CCD camera 23 can send the taken photos to the controller, and the controller compares the taken photos with the stored initial photos to determine whether they are qualified based on the comparison results.

[0072] Working principle:

[0073] The movable plate 333 is then rotated so that the movable plate 333 drives the rectangular block 335 to rotate around the rotating shaft on the second fixed plate 332 as the center of the circle until the movable plate 333 is away from the unwinding roller 31; then the blocking member 71 is rotated upward so that the blocking member 71 drives the distance adjusting member 73 and the connecting plate 722 to take the rotating shaft on the fixed seat 721 as the center of the circle, so that the spring 724 is stretched by force until the blocking member 71 is away from the unwinding roller 31. The plastic film roll to be detected can be sleeved on the surface of the unwinding roller 31; similarly, the plastic film roll to be wound can be sleeved on the surface of the winding roller 32 according to the above steps; finally, the movable plate 333 is rotated in the opposite direction to the maximum limit, and the electric telescopic rod 81 is started, so that the output end of the electric telescopic rod 81 drives the push plate 82, the second fixed plate 332, the movable plate 333 and the rectangular block 335 to gradually approach the first fixed plate 331, until the rectangular block 335 is stuck in the inner cavity of the rectangular groove 334, and then one end of the plastic film can be passed through the lower roller 52 and the upper roller 53 and the inner cavity of the detection mechanism 2, and finally one end of the plastic film is fixed on the plastic film roll with winding, and the blocking member 71 is released. Through the self-gravity of the blocking member 71 and the elastic restoring force of the spring 724, the blocking member 71 is restored to the original state, and the assembly operation of the plastic film can be completed;

[0074] S2, turn the second knob 733, the second knob 733 drives the bidirectional screw 731 to rotate, under the action of the thread, the bidirectional screw 731 drives the two movable sleeves 732 on its surface to move toward each other, the movable sleeve 732 slides on the surface of the guide rod 734, and the movable sleeve 732 drives the stopper 711 and the wear-resistant pad 712 to move along the axial direction of the bidirectional screw 731 until one side of the stopper 711 contacts the side edge of the film, thereby completing the preliminary limiting operation of the film, so that the film can be prevented from being offset during the process of winding and unwinding;

[0075] S3, turn the first knob 67, the first knob 67 drives the stud 63 to rotate, under the action of the thread, the stud 63 drives the screw sleeve 64 to move downward in the inner cavity of the second through hole 62, the screw sleeve 64 drives the connecting rod 65, the slider 55 and the upper roller 53 to move downward synchronously, one end of the connecting rod 65 slides in the inner cavity of the second sliding hole 66, and the other end of the connecting rod 65 slides in the inner cavity of the first sliding hole 57 until the bottom of the upper roller 53 contacts the surface of the plastic film, and the secondary limiting operation of the plastic film is completed, which effectively ensures that the film entering the inner cavity of the detection box 21 is stably maintained in a horizontal state;

[0076] S4, start the reduction motor 41, the output shaft of the reduction motor 41 drives the winding roller 32 to rotate through the pulley 42 and the belt, and then can drive the plastic film to move and reel up. During the movement of the plastic film, the non-contact measurement characteristics of the laser displacement sensor 22 can be used to detect the thickness and flatness of the film, and at the same time, possible defects such as wrinkles and damage can be detected. The CCD camera 23 and the fill light 24 are used in conjunction to collect the gloss area on the surface of the film. The CCD camera 23 sends the taken photos to the controller, and the controller compares the taken photos with the stored initial photos. The comparison results are used to determine whether the film is qualified. Through the setting of the laser engraving machine 26, when the unqualified position of the film moves to the position below it, the rodless cylinder 25 drives the laser engraving machine 26 to move horizontally, and then the unqualified words and regional cutting lines can be engraved on the surface of the film, which is convenient for subsequent slitting operations.

[0077] In summary, the anti-wrinkle plastic film flattening detection device, by turning the second knob 733, the second knob 733 drives the corresponding bidirectional screw 731 to rotate synchronously, which can drive the corresponding two blocking members 71 on the bidirectional screw 731 to move toward or away from each other until the opposite sides of the two blocking members 71 located at the front and rear are in contact with the two sides of the plastic film, so that the two sides of the plastic film can be limited, and the plastic film can be effectively prevented from being offset during the process of winding and unwinding. Furthermore, the distance adjusting member 73 can make the blocking member 71 suitable for plastic films that do not pass through a wide width, which helps to improve the application range of the blocking member 71 and avoid the existence of usage limitations. There is no need to prepare different types of limit mechanisms 7, which reduces the use Cost; by starting the electric telescopic rod 81, the output end of the electric telescopic rod 81 can drive the second fixed plate 332, the movable plate 333 and the rectangular block 335 to move horizontally, and then bend the blocking member 71 upward, and finally enable the blocking member 71 to rotate with the rotating shaft on the fixed seat 721 as the center of the circle until the blocking member 71 is away from the plastic film, so that the plastic film is free from constraint, and then the plastic film roll on the unwinding roller 31 or the winding roller 32 can be loaded and unloaded, so that the blocking member 71 can be quickly separated from the surface of the plastic film and the conveying mechanism 3 through the rotating member 72, and there is no need to disassemble and assemble the limiting mechanism 7, thereby reducing the loading and unloading steps of the plastic film roll and reducing the labor intensity.
