Description

Technical Field

[0001] This utility model relates to the field of thin film detection technology, specifically a thickness detection device for CPP film preparation. Background Technology

[0002] Cast polypropylene film (CPP) is a polypropylene film produced using a casting process. It can be divided into general-purpose CPP film, aluminized CPP film, and retort grade CPP film.

[0003] During the preparation of CPP film, a thickness gauge is required to measure the thickness. This measurement ensures the uniformity of the CPP film thickness, improves product quality, reduces the scrap rate, and meets customers' precise requirements for film thickness.

[0004] The reference patent number "CN220751130U" entitled "A Thin Film Product Thickness Detection Device" addresses the issue that "when detecting the thickness of thin film products, existing detectors can be used to measure the film thickness. The film is placed directly under the detector, and the measurement can be performed. To improve the detection effect, the film is flattened, specifically by holding one end of the film with one hand and smoothing it with the other. However, if the film is directly under the detector and accidental contact occurs, the detector may injure the hand." However, it also has some drawbacks. For example, the platform surface in the aforementioned application lacks a cleaning mechanism, making it susceptible to interference from dust and impurities on the platform surface during film thickness measurement. This can lead to dust and impurities affecting the standardization of film thickness measurement data. Furthermore, the aforementioned application requires multiple transmission components for film stretching, making the operation overly complex and inconvenient for personnel, thus affecting detection efficiency. Therefore, this paper proposes a thickness detection device for CPP film preparation to solve the aforementioned technical problems. Utility Model Content

A detection support frame is fixedly connected to the rear side of the upper limit support frame on the operating platform. An explosion-proof lighting lamp is fixedly connected to the inner side wall of the detection support frame. A servo electric cylinder is fixedly connected to the top of the detection support frame.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a thickness detection device for CPP membrane preparation, which has the following beneficial effects:

[0016] This thickness detection device for CPP film preparation, through the coordinated arrangement of an operating table, a CPP film detection platform, a limiting slide groove, a dust collection box, a pull handle, a limiting support frame, a servo motor, a one-way screw, a limiting moving block, and a cleaning brush, operates as follows: Before CPP film thickness detection, the controller starts the servo motor, driving the one-way screw to rotate left and right. This causes the limiting moving block to move the cleaning brush threadedly across the surface of the one-way screw, cleaning the CPP film detection platform. The cleaned dust and impurities are then swept into the dust collection boxes on both sides for collection. Personnel can then pull out the dust collection boxes through the limiting slide groove using the pull handle to centrally clean the impurities and dust. This device effectively cleans the platform and collects impurities and dust during CPP film thickness detection, facilitating centralized cleaning and improving the accuracy of CPP film thickness detection data. The installation of explosion-proof lighting facilitates CPP film thickness testing at night. The system utilizes a servo electric cylinder, a stabilizing lifting plate, an auxiliary lifting stabilizer, a thickness gauge, torsion springs, leveling rollers, and sponge protective pads. During operation, the CPP film to be tested is laid on the platform. The operator then activates the servo electric cylinder via the controller, causing the stabilizing lifting plate, auxiliary lifting stabilizer, thickness gauge, torsion springs, and leveling rollers to descend steadily until the sponge protective pads on the two leveling rollers contact the CPP film. The tilting force of the torsion springs stretches the CPP film to both sides, allowing the thickness gauge to measure its thickness. This system effectively stretches and flattens the CPP film during thickness testing, resulting in simple operation, good results, and improved efficiency in CPP film thickness testing.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-2This utility model provides a technical solution: a thickness detection device for CPP film preparation, including an operating table 1.

During use, before CPP film thickness detection, the controller starts the servo motor 7, which drives the one-way screw 8 to rotate left and right. This causes the limiting moving block 9 to move the cleaning brush 10 along the surface of the one-way screw 8, cleaning the CPP film detection platform 2. The cleaned dust and impurities are then swept into the dust collection boxes 4 on both sides for collection. The operator can then hold the pull handle 5 and pull out the dust collection box 4 through the limiting slide groove 3 to remove the impurities and dust. The dust is centrally cleaned, thus serving to clean the platform and collect impurities and dust during CPP film thickness testing. This facilitates centralized cleaning by personnel and improves the accuracy of CPP film thickness testing data. A CPP film testing platform 2 is fixedly connected to the middle of the upper surface of the operating table 1. Limiting grooves 3 are opened on both the left and right sides of the CPP film testing platform 2 on the upper surface of the operating table 1. Dust collection boxes 4 are slidably connected inside the two limiting grooves 3.

An explosion-proof lighting lamp 12 is fixedly connected to the inner wall of the detection support frame 11. The explosion-proof lighting lamp 12 facilitates the operation of CPP film thickness detection at night. A servo electric cylinder 13 is fixedly connected to the top of the detection support frame 11.

Then, the operator starts the servo electric cylinder 13 through the controller to drive the stabilizing lifting plate 14, the auxiliary lifting stabilizing rod 15, and the thickness detector 16. The torsion spring 17 and the leveling roller 18 move downwards steadily until the sponge protective pads 19 on the surfaces of the two leveling rollers 18 contact the CPP film. The tilting force of the torsion spring 17 stretches and flattens the CPP film to both sides. Then, the thickness gauge 16 performs thickness detection on the flat CPP film, effectively stretching and flattening the film on both sides during thickness detection. This method is simple to operate, effective, and improves the efficiency of CPP film thickness detection. A stabilizing lifting plate 14 is fixedly connected to the bottom of the servo electric cylinder 13. Auxiliary lifting stabilizing rods 15 are fixedly connected to both sides of the top of the stabilizing lifting plate 14. The thickness gauge 16 is fixedly connected to the bottom of the stabilizing lifting plate 14, and torsion springs 17 are fixedly connected to both the left and right sides of the thickness gauge 16 at the bottom of the stabilizing lifting plate 14.A leveling roller 18 is fixedly connected to the end of the torsion spring 17 away from the stabilizing lifting plate 14. A pull handle 5 is fixedly connected to the outer wall of the dust collection box 4. The bottom brush surface of the cleaning brush 10 is movably connected to the surface of the CPP film inspection platform 2. A power supply box is electrically connected to the rear side wall of the explosion-proof lighting lamp 12. A control switch is provided on the surface of the power supply box. The torsion angles of the two torsion springs 17 are relatively inclined. A sponge protective pad 19 is sleeved on the surface of the leveling roller 18.

[0022] In summary, this thickness detection device for CPP film preparation, through the coordinated arrangement of the operating table 1, CPP film detection platform 2, limiting slide 3, dust collection box 4, pull handle 5, limiting support frame 6, servo motor 7, one-way screw 8, limiting moving block 9, and cleaning brush 10, operates as follows: before CPP film thickness detection, the controller starts the servo motor 7 to drive the one-way screw 8 to rotate left and right, causing the limiting moving block 9 to move the cleaning brush 10 along the surface of the one-way screw 8 to clean the CPP film detection platform 2. The cleaned dust and impurities are then swept into the dust collection boxes 4 on both sides for collection. Personnel can then use the pull handle 5 to pull out the dust collection box 4 through the limiting slide 3 for centralized cleaning of impurities and dust. This serves to clean the platform and collect impurities and dust during CPP film thickness detection, facilitating centralized cleaning and improving the accuracy of CPP film thickness detection data. Furthermore, it prevents... The inclusion of the explosion-proof lighting 12 facilitates CPP film thickness testing at night. Through the coordinated arrangement of the servo electric cylinder 13, stabilizing lifting plate 14, auxiliary lifting stabilizing rod 15, thickness gauge 16, torsion spring 17, leveling roller 18, and sponge protective pad 19, the CPP film to be tested is laid on the platform surface. The operator then activates the servo electric cylinder 13 via the controller, driving the stabilizing lifting plate 14, auxiliary lifting stabilizing rod 15, thickness gauge 16, torsion spring 17, and leveling roller 18 downwards until the sponge protective pad 19 on the surface of the two leveling rollers contacts the CPP film. The tilting force of the torsion spring 17 stretches the CPP film to both sides, allowing the thickness gauge 16 to perform thickness testing on the flat CPP film. This effectively stretches and flattens the CPP film during thickness testing, resulting in simple operation, good results, and improved efficiency in CPP film thickness testing.
