Description

Technical Field

[0001] This utility model relates to the technical field of plastic film production equipment, specifically to a thickness measuring device for plastic film production equipment. Background Technology

[0002] Plastic film is a thin, soft, transparent or semi-transparent film material made from high molecular polymers through processes such as blow molding, casting, and calendering. It has properties such as light weight, flexibility, waterproofness, moisture resistance, barrier properties, and transparency, and is widely used in packaging, agriculture, industry, daily life, and many other fields.

[0003] Thickness measuring devices are frequently used in the production of plastic films. While existing thickness measuring devices can perform the function of measuring thickness, they are easily affected by dust in the environment. Dust particles can easily adhere to the lens of the thickness gauge, directly interfering with the measurement optical path and signal transmission. They can also cause significant deviations in measurement data due to scattering and absorption of measurement light, or even completely interrupt the measurement process. Therefore, improvements are needed. Utility Model Content

[0026] like Figures 1-7The diagram illustrates a thickness measuring device for a plastic film production equipment according to an embodiment of this disclosure. The device includes a mounting box 1, a mounting plate 2 fixedly connected to the bottom of the inner cavity of the mounting box 1, a first wheel 3 movably mounted on the top of the mounting plate 2, a dual-axis motor 4 fixedly connected to the middle of the top of the mounting box 1, a rotating shaft 5 fixedly sleeved at the other end of the output shaft of the dual-axis motor 4, a rotating rod 6 fixedly sleeved on the outer surface of the rotating shaft 5, a round shaft 7 fixedly sleeved inside the other end of the rotating rod 6, a rectangular plate 8 movably connected to the outer surface of the round shaft 7, a protective plate 9 fixedly connected to the bottom of the rectangular plate 8, the outer surface of the protective plate 9 movably connected to the inner surface of the mounting box 1, and a second wheel 10 movably mounted on the bottom of the protective plate 9.

[0027] The diameter of the circular shaft 7 is the same as the width of the inner cavity of the rectangular plate 8. This design allows the circular shaft 7 to move within the inner cavity of the rectangular plate 8, thereby driving the rectangular plate 8, the protective plate 9, and the second circular wheel 10 to move downward as a whole.

[0028] In some examples, the interior of the mounting box 1 is provided with a slide groove 11, the inner surface of the slide groove 11 is movably connected to a limiting block 12, and the inner side of the limiting block 12 is fixedly connected to the outer side of the protective plate 9.

[0029] The design of the slide 11 and the limiting block 12 serves to limit the movement of the protective plate 9.

[0030] In some examples, a protective shell 13 is fixedly connected to the outside of the mounting box 1, and a drive motor 14 is fixedly installed inside the protective shell 13.

[0031] The protective shell 13 is designed to protect the drive motor 14.

[0032] In some examples, the other end of the output shaft of the drive motor 14 is fixedly sleeved with a lead screw 15, the other end of which passes through the protective shell 13 and the mounting box 1 and extends into the interior of the mounting box 1. The outer surface of the lead screw 15 is threaded with a movable block 16.

[0033] The lead screw 15 and the movable block 16 adopt a threaded connection design, which can form a self-locking structure by utilizing the friction between the threads.

[0034] In some examples, the front of the movable block 16 is movably connected to a thickness gauge 17, and the back of the thickness gauge 17 is fixedly connected to a connecting block 18, with the outer surface of the connecting block 18 movably connected to the inner surface of the movable block 16.

[0035] This design makes the thickness gauge 17 easy to install and replace quickly.

[0036] In some examples, a round rod 19 is fixedly installed inside the mounting box 1, and the outer surface of the round rod 19 is movably sleeved with the inner surface of the movable block 16.

[0037] The design of the round rod 19 serves to limit the movement of the movable block 16, ensuring the stability of the horizontal movement of the movable block 16.

[0038] In some examples, the top of the movable block 16 is fixedly connected to a fixed block 20, and the fixed block 20 is internally threaded with a threaded rod 21.

[0039] The design of the fixing block 20 serves to support and lock the threaded rod 21.

[0040] In some examples, a rectangular block 22 is movably sleeved on the outer surface of the other end of the threaded rod 21. A connecting rod 23 is hinged to both the left and right sides of the front of the rectangular block 22. A movable plate 24 is hinged to the other end of the connecting rod 23. The inner side of the movable plate 24 is movably connected to the outer side of the movable block 16. A pin 25 is fixedly connected to the bottom of the inner side of the movable plate 24. The inner side of the pin 25 passes through the movable block 16 and the connecting block 18 in sequence and extends into the interior of the connecting block 18.

[0041] When the two pins 25 move in opposite directions to the outside of the connecting block 18, the locking effect on the connecting block 18 will be released.

[0042] In some examples, the top of the movable block 16 is fixedly connected to a limit rod 26, and the outer surface of the limit rod 26 is movably sleeved with the inner surface of the movable plate 24.

[0043] The design of the limit rod 26 serves to limit the movement of the movable plate 24, enabling the movable plate 24 to move horizontally stably.

[0044] In some examples, the internal movable mounting of the mounting box 1 is a third wheel 27 located below the lead screw 15, and the outer surface of the third wheel 27 is smooth.

[0045] The design of the third wheel 27 serves to guide and support the plastic film.

[0046] Working principle and usage process of this utility model: When measuring the thickness of the plastic film, the dual-axis motor 4 is first started, which causes the two rotating shafts 5 to drive the two rotating rods 6 to rotate, which in turn causes the two round shafts 7 to rotate and drive the two rectangular plates 8 to move downward. This causes the two protective plates 9 to drive the two second round wheels 10 to move downward. With the cooperation of the two mounting plates 2 and the two first round wheels 3, the inner cavity of the mounting box 1 is sealed, which reduces the influence of external dust on the thickness gauge 17 and ensures the accuracy of the thickness gauge 17. Then, the drive motor 14 is started, which causes the lead screw 15 to rotate and drive the movable block 16 to move left and right, which in turn drives the thickness gauge 17 to move left and right to measure the thickness of the plastic film.

[0047] When the thickness gauge 17 is damaged, it needs to be disassembled and replaced. At this time, the rotating threaded rod 21 moves forward, which will drive the rectangular block 22 to move forward. This will cause the two connecting rods 23 to rotate, which will drive the two moving plates 24 to move in opposite directions. This will cause the two pins 25 to move in opposite directions to release the locking effect on the connecting block 18, thus realizing the quick installation and replacement of the thickness gauge 17 and improving the convenience of the device.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
