Description

Technical Field

[0001] This utility model relates to the field of membrane quality testing, and in particular to a PVC stretch film quality testing device. Background Technology

[0002] After the PVC stretch film completes its production process, it must undergo rigorous quality inspection to ensure that its performance and appearance meet standard requirements. The inspection typically covers multiple core indicators such as tensile strength, puncture resistance, and flame retardancy, while also requiring a detailed inspection of the film's outer surface quality. Because the production environment cannot completely prevent the intrusion of insects and other biological organisms, tiny insects and other foreign objects may be mixed into the raw materials during processing, ultimately forming defects such as black spots on the film surface. Therefore, a comprehensive scan of the film surface using a high-precision visual inspection system is necessary after processing to ensure the consistency of its appearance quality.

[0003] However, visual inspection systems face environmental interference issues during long-term operation: dust adsorption and biological attachment (such as insect residue) at the processing site can easily contaminate camera lenses, causing blurred images and reduced contrast. This image quality degradation directly affects the accuracy of defect recognition algorithms, potentially leading to two types of erroneous judgments: first, misjudging qualified films as defective products and scrapping them; second, missing real defects, allowing substandard products to enter the market. The former directly wastes raw materials and production costs, while the latter can damage product reputation. Therefore, a device is needed to solve these problems. Utility Model Content

[0017] According to one embodiment of the present invention, in conjunction with Figures 1-4 As shown.

[0018] A PVC stretch film quality inspection device includes: a support frame 1 and a camera 2 bolted to the support frame 1. An L-shaped bracket 4 for support is welded and fixed to the bottom of the support frame 1. It also includes a rotating shaft 6 rotatably mounted on the bracket 4. A power assembly 5 for driving the rotating shaft 6 to rotate is fixed to the bottom of the bracket 4 via a mounting bracket. The power assembly 5 is a motor, and the motor output is connected to the rotating shaft 6 via a coupling. It also includes a transparent plate 3 closely attached to the bottom of the camera 2. The transparent plate 3 protects the lens of the camera 2 and does not affect the normal image acquisition operation of the camera 2. The transparent plate 3 can be made of transparent acrylic, preferably glass. The transparent plate 3 is welded and fixed to the outside of the rotating shaft 6, and the power assembly 5 drives the transparent plate 3 to rotate via the rotating shaft 6. It also includes a cleaning part that is pressed tightly against the bottom of the transparent plate 3 by the squeezing part. The cleaning part consists of a box 7 with an open top and a cleaning sponge 8 that is adhered to the inside of the box 7. When the bottom of the rotating transparent plate 3 passes through the cleaning sponge 8, it is cleaned by the cleaning sponge 8 to ensure the accuracy of the image captured by the camera 2 and prevent misjudgment.

[0019] Specifically, the squeezing part includes a movable rod 9 that is movably inserted into the bottom of the bracket 4, with the top of the movable rod 9 welded and fixed to the bottom of the box body 7; it also includes a spring 10 welded and fixed between the movable rod 9 and the bracket 4, wherein the spring 10 is in a stretched state, and the elastic force of the spring 10 causes the movable rod 9 to squeeze the box body 7 upward, so that the cleaning sponge 8 is tightly attached to the bottom of the transparent plate 3, ensuring the cleaning effect.

[0020] In this embodiment, a mechanism for adding cleaning fluid to the inside of the box 7 is also included.

[0021] Specifically, the adding mechanism includes a housing 14 for housing the cleaning fluid storage bottle, wherein the housing 14 is welded and fixed to one side of the support frame 1, the top and bottom of the housing 14 are open, and the bottom opening edge is tapered towards the center of the housing 14, supporting the cleaning fluid storage bottle through the tapered bottom opening; it also includes a groove 11 formed on the support frame 1 that penetrates one side of the housing 14, and an electric push rod 12 is fixed inside the groove 11 by a mounting bracket; it also includes a squeezing plate 13 fixed to the extended end of the electric push rod 12 by bolts, the electric push rod 12 drives the squeezing plate 13 to squeeze the cleaning fluid storage bottle, squeezing the cleaning fluid into the box 7.

[0022] Working principle: The camera 2 is installed at the bottom of the support frame 1, and the bracket 4 is installed on the support frame 1. At this time, the transparent plate 3 is in close contact with the bottom of the camera 2. The camera 2 performs image acquisition through the transparent plate 3, and identifies the image of the film's surface to remove unqualified products. Before each use of camera 2, power component 5 is activated, or when camera 2 is used continuously, power component 5 is activated at regular intervals to drive the rotating shaft 6 to rotate, which in turn drives the transparent plate 3 to rotate. When the transparent plate 3 passes through the cleaning sponge 8, it is wiped clean by the cleaning sponge 8. During the cleaning process, the elasticity of spring 10 makes the cleaning sponge 8 stick tightly to the bottom of the transparent plate 3, thus further improving the cleaning effect. During cleaning, the electric push rod 12 is activated to perform a reciprocating motion. The electric push rod 12 squeezes the cleaning solution storage bottle through the squeezing plate 13, squeezing out the cleaning solution inside the storage bottle. The squeezed-out cleaning solution enters the box 7 and is absorbed by the cleaning sponge 8. The cleaning effect is further improved by adding cleaning solution.

[0023] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
