Description

Technical Field

[0001] This utility model belongs to the field of thin film testing technology and relates to a performance testing device for antibacterial and antifungal films. Background Technology

[0002] Antibacterial and antifungal films are special film materials whose main characteristic is their ability to effectively inhibit the growth of bacteria and mold, leading to their widespread application in many fields. While the antibacterial and antifungal properties are among the most prominent and important characteristics of these films, puncture resistance testing is necessary to ensure their reliability and durability in practical use. Puncture resistance testing not only helps evaluate the film's protective ability against external physical damage but also further verifies its overall performance in complex environments. This is crucial for improving the overall quality of the product and meeting the needs of different application scenarios.

[0003] In existing testing devices, the film that has already been tested must be removed before the next film to be tested can be installed. Furthermore, the film placement tube is fixed, making it easy to bump into the testing needle during film removal and installation. Therefore, it is essential to design a performance testing device for antibacterial and antifungal films. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a performance testing device for antibacterial and antifungal films.

[0005] The objective of this utility model can be achieved through the following technical solution: a performance testing device for an antibacterial and antifungal film, comprising a frame, a support frame fixed on the frame, a lifting platform that can be raised and lowered on the support frame, one end of the lifting platform being fixedly connected to a force-sensitive sensor, the other end of the force-sensitive sensor being fixedly connected to a detection needle, a guide rail being horizontally fixed on the frame, two switching seats being slidably connected on the guide rail, a film placement cylinder being fixedly installed on the switching seats, a clamping ring being detachably connected to the film placement cylinder by a locking screw, an iron positioning ear being provided on the film placement cylinder, and a mounting base being fixed on the support frame, with two electromagnets fixed on the mounting base, and the electromagnets being able to magnetically attract and hold the corresponding iron positioning ear.

[0006] An electronic control panel is also fixed on the frame, and the force sensor and electromagnet are both electrically connected to the electronic control panel via circuits.

[0007] The locking screw is a hand-tightening component.

[0008] The switching base is also equipped with a handle.

[0009] Both ends of the guide rail are fixed with limiting blocks.

[0010] The film placement tube also has two connecting lugs.

[0011] Compared with existing technologies, this antibacterial and antifungal film performance testing device has the following advantages: In this invention, the film placement tube is designed to be movable. When assembling or disassembling the antibacterial and antimildew film, the film placement tube can be kept away from the stand, and the clamping ring is less likely to collide with the detection needle. At the same time, since there are two film placement tubes, one can be used for testing and the other can be used for disassembly and assembly, which greatly facilitates the puncture resistance test of the antibacterial and antimildew film.

[0013] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0014] like Figures 1-4As shown, the performance testing device for this antibacterial and antifungal film includes a frame 1, on which a support frame 4 is fixed. The support frame 4 has a lifting platform 3 that can move up and down as needed. The lifting platform 3 is fixedly connected to one end of a force sensor 5, and the other end of the force sensor 5 is fixedly connected to a detection needle 2. A guide rail 11 is horizontally fixed on the frame 1, and two switching seats 10 are slidably connected to the guide rail 11. A film placement cylinder 9 is fixedly installed on the switching seats 10. Specifically, the film placement cylinder 9 also has two connecting ears 9b, which are used to fix the film placement cylinder 9 to the switching seats 10. The film placement cylinder 9 is secured to the switching seats 10 by locking screws 1. The support frame 4 is detachably connected to a clamping ring 8. The film placement cylinder 9 has iron positioning ears 9a. The support frame 4 is also fixed with a mounting base 7. Two electromagnets 6 are fixed on the mounting base 7. The electromagnets 6 can magnetize the corresponding iron positioning ears 9a. With this structure, an antibacterial and anti-mildew film is placed on the film placement cylinder 9. The clamping ring 8 is installed. The film placement cylinder 9 is moved to the support frame 4 so that the iron positioning ears 9a abut against the electromagnets 6 on that side. The electromagnets 6 can fix the film placement cylinder 9. At this time, the axis of the film placement cylinder 9 just overlaps with the axis of the detection needle 2. The detection needle 2 moves downward to complete the puncture resistance test of the antibacterial and anti-mildew film.

[0015] An electronic control panel 15 is also fixed on the frame 1. The force sensor 5 and the electromagnet 6 are both electrically connected to the electronic control panel 15 through wiring. This adopts existing technology, and its electrical connection does not need to be redesigned.

[0016] Locking screw 14 is a hand-tightening component.

[0017] A handle 13 is also installed on the switch 10.

[0018] Both ends of the guide rail 11 are fixed with limiting blocks 12.

[0019] In this invention, the film placement cylinder 9 is designed to be movable. When disassembling or assembling the antibacterial and antimildew film, the film placement cylinder 9 can be moved away from the stand 4, and the clamping ring 8 is less likely to collide with the detection needle 2. At the same time, since there are two film placement cylinders 9, one can be used for testing and the other can be used for disassembly and assembly operations, which greatly facilitates the puncture resistance test of the antibacterial and antimildew film.

[0020] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0021] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
