[0002] PVDC film is a polyethylene-based packaging material, its full name is polyethylene-1,2-dichloroethylene copolymer, also known as Saran film. PVDC film has excellent gas barrier properties and freshness preservation, and is often used in food packaging, pharmaceutical packaging and other product packaging that needs to remain fresh and moisture-proof. Due to its excellent air tightness and freshness preservation, PVDC film is widely used in the food packaging industry. It can effectively prevent food oxidation and corruption, slow down food deterioration, and is also moisture-proof and odor-proof. PVDC film is a commonly used plastic packaging film material that effectively protects the quality of food and extends the shelf life.

[0003] During the production process of PVDC membrane, the thickness of the membrane is generally detected in real time at one or several workstations. After the membrane is produced, it is necessary to conduct sampling quality inspection on its thickness to ensure product quality. When conducting sampling inspection, the sample can be attached to the tooling panel to stabilize the state of the membrane, and it is easy to ensure the verticality of the inspection direction and the membrane, thereby ensuring the inspection accuracy. At present, when conducting product quality inspection, the samples are uniformly transported to the quality inspection room for unified inspection. If it is necessary to conduct random inspections at the production site to examine the product quality, it is necessary to provide a simple, portable thickness detection device that can be applied to the production site.

DETAILED DESCRIPTION

[0040] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with examples and drawings. The illustrative implementation scheme of the present application and its description are only used to explain the present application and are not intended to limit the present application.

[0041] like Figure 1-2As shown, the embodiment of the present application is a simple and portable film thickness detection device, which includes a base 1, a mounting base 2, a movable positioning plate 3, a driving component and a thickness detection component; the base 1 can be specifically constructed as a rectangular plate to provide stable support for the entire detection device; the mounting base 2 is arranged on the base 1, and the mounting base 2 can be specifically constructed as a rectangular parallelepiped shape, and an operating groove 20 is arranged on the mounting base 2, and a mounting groove 19 is also arranged on the mounting base 2, wherein the groove openings of the mounting groove 19 and the operating groove 20 are orthogonal to each other, and the mounting groove 19 is connected with the operating groove 20 so that when the sample 4 is located in the mounting groove 19, part of the plate surface can be exposed to the air through the operating groove 20. In other words, the mounting base 2 is hollow in structure as a whole through the arrangement of the mounting groove 19 and the operating groove 20, and the mounting groove 19 and the operating groove 20 can both be configured as a rectangular parallelepiped shape, wherein the mounting groove 19 and the operating groove 20 are arranged in a rectangular parallelepiped shape. The cross-sectional area of ​​the mounting groove 19 is larger than the cross-sectional area of ​​the operating groove 20; the movable positioning plate 3 is slidably arranged in the mounting groove 19, wherein a clamping gap is formed between the plate surface of the movable positioning plate 3 close to the operating groove 20 and the groove wall of the mounting groove 19, and the shape of the movable positioning plate 3 is adapted to the cross-sectional shape of the mounting groove 19, that is, the plate surface area of ​​the movable positioning plate 3 is the same as the cross-sectional area of ​​the mounting groove 19; the driving component is arranged on the pedestal 1 and is used to drive the movable positioning plate 3 to slide in the mounting groove 19 so that the clamping gap changes, and the driving component can be manual or automatic. When the driving component is automatic, a driving source such as a motor 14, a cylinder, an electric cylinder, etc. can be configured for the driving component. When the driving component is manual, power can be provided manually; the thickness detection component is connected to the pedestal 1 and corresponds to the notch position of the operating groove 20, and the thickness detection component is used to detect the thickness of the membrane 5.

[0042] The simple and portable membrane thickness detection device provided in the embodiment of the present application, after the driving source is configured for the driving component, can drive the movable positioning plate 3 to move in the installation groove 19 through the driving component, thereby changing the distance between the plate surface of the movable positioning plate 3 and the groove wall of the installation groove 19, that is, changing the clamping gap, and placing the sample 4 in the clamping gap. After the clamping gap is reduced, the sample 4 can be clamped. After the sample 4 is clamped, the membrane 5 on the sample 4 is located in the operating groove 20. Since the sample 4 is clamped and fixed, the state of the membrane 5 is stable, that is, the thickness detection sensor 9 can maintain a stable vertical relationship with the membrane 5 during the detection process, thereby ensuring the reliability of the detection result.

[0043] The simple and portable film thickness detection device provided in the embodiment of the present application has a simple structure and is easy to move, that is, it has good portability, and at the same time has the advantages of simple operation and reliable detection results.

[0044] In order to ensure the posture stability of the movable positioning plate 3 during the movement and prevent the movable positioning plate 3 from being deflected and stuck in the mounting groove 19 during the movement, in some optional embodiments, a plurality of guide columns 15 are provided on the movable positioning plate 3.

For example, the driving component and the movable positioning plate 3 can slide relative to each other to tend to move the movable positioning plate 3 in the mounting groove 19. When the driving mode between the driving component and the movable positioning plate 3 is a contact type driving mode, the movable positioning plate 3 may not be able to return to its original position after the driving source is withdrawn. That is, after the thickness detection process is completed, a small clamping gap is still maintained between the movable positioning plate 3 and the groove wall of the mounting groove 19, which will be not conducive to the removal of the sample 4 in the clamping gap. Therefore, in some optional embodiments, an elastic member 16 is connected between the movable positioning plate 3 and the mounting seat 2 to make the movable positioning plate 3 have a movement tendency close to the base 1; in actual implementation, the elastic member 16 can be configured as a coil spring.

Therefore, in some optional embodiments, a baffle 6 is rotatably connected to the mounting seat 2. Specifically, the baffle 6 can be rotatably connected to the mounting seat 2 through a spring hinge. The spring hinge is commonly found in applications such as cabinets and drawers, and its specific structure is not repeated here.
