[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] First Embodiment Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of an online PE protective film thickness detector provided by this utility model; Figure 2 for Figure 1 The enlarged schematic diagram of part A shown below; Figure 3 for Figure 1 The enlarged schematic diagram of section B is shown. An online PE protective film thickness measuring instrument includes: The detector body consists of: 1. connecting cable; 2. detection head; 3. connecting sleeve; 4. movable components; 5. two connecting plates; 6. and multiple rollers; 7. The detection head 3 is connected to one end of the detector body 1 via the connecting line 2; The connecting sleeve 4 is fitted onto the surface of the detection head 3; The active component 5 is disposed on the surface of the connecting sleeve 4; The two connecting plates 6 are respectively disposed on both sides of the bottom of the movable component 5; The multiple rollers 7 are respectively disposed on both sides of one side of the two connecting plates 6.

[0019] The main body of the detector consists of one layer: a display screen (displaying measurement data and operation menu), operation buttons (for functions such as power-on, calibration, and mode switching), a signal processing module (analyzing and converting magnetic / eddy current signals into thickness values), and a battery compartment (powered by AA batteries).

[0020] The working principle of the detection head 3 is as follows: Based on the proportional relationship between the attractive force and the distance between the permanent magnet and the magnet, when measuring the non-magnetic coating on the ferromagnetic material, the probe transmits magnetic flux to the ferromagnetic substrate through the non-ferromagnetic coating, captures the change in the distance between the probe and the coating, and calculates the coating thickness.

[0021] The movable component 5 includes a fixed ring 51, two connecting brackets 55, two movable rods 52, two springs 53, and two stops 54. The fixed ring 51 is sleeved on the surface of the connecting sleeve 4. The two connecting brackets 55 are symmetrically connected to both sides of the surface of the fixed ring 51. The two movable rods 52 are respectively disposed inside the two connecting brackets 55. The bottom of the movable rods 52 is connected to the connecting plate 6.

[0022] The two springs 54 are respectively sleeved on the surfaces of the two movable rods 52.

[0023] The two stops 54 are respectively connected to the top ends of the two movable rods 52.

[0024] The connecting frame 55 has an openable through hole that matches the movable rod 52. The spring 53 is used to facilitate the return of the detection head 3 to its original position when not in use. The roller 7 is rotatably connected to the connecting plate 6 via a rotating shaft. The stop block 54 is used to prevent the movable rod 52 from falling off the connecting frame 55.

[0025] The working principle of the online PE protective film thickness detector provided by this utility model is as follows: In use, when the detection head 3 is used to detect the thickness of the PE protective film, the detection head 3 is first placed on the surface of the PE protective film. Then, the detection head 3 is moved downward by pushing the connecting sleeve 4. When the connecting sleeve 4 moves downward, it moves on the surface of the two movable rods 52 through the fixing ring 51 and the two connecting brackets 55. When the two connecting brackets 55 move on the surface of the two movable rods 52, they squeeze the spring 53 on the surface until the bottom of the detection head 3 contacts the surface of the PE protective film. The thickness information of the PE protective film can then be transmitted to the inside of the detector body 1 through the detection head 3 and the connecting line 2 for data viewing. When changing the detection position on the surface of the PE protective film, the pressed detection head 3 is first released and returned to its original position by the spring 53. Then, the detection head 3 is moved to another position by pushing the multiple rollers 7 to perform the detection operation.

[0026] Compared with related technologies, the online thickness detector for PE protective film provided by this utility model has the following advantages: This utility model provides an online PE protective film thickness measuring instrument.

It also facilitates the operator's portable operation and stability of the measuring head 3.
