[0022] During the production process of PC film, the thickness needs to be tested to determine whether the product meets the standards. In a dry environment, due to the presence of static electricity, the PC film is easily attracted by tiny particles such as dust during the traction process after extrusion molding. Static electricity can easily affect the normal use of thickness detection equipment, and particles can also affect the accuracy of thickness detection, which is not conducive to production use.

[0023] For this purpose, refer to Figure 1 and Figure 2, a PC film thickness measuring device proposed by the utility model, includes a frame 100, an electrostatic elimination component 200, a dust sticking component and a thickness detection component 600. The electrostatic elimination component 200 is connected to the frame 100 and is used to eliminate the static electricity of the PC film. The dust sticking component is connected to the frame 100 and is located at the rear end of the electrostatic elimination component 200. The dust sticking component includes a dust sticking roller 300. A pressure roller 400 is arranged above or below the dust sticking roller 300 to press the PC film against the dust sticking roller 300. The dust sticking roller 300 is connected to the frame through a lifting component 500. The lifting component 500 is used to drive the dust sticking roller 300 to move up and down to get close to or away from the pressure roller 400. The thickness detection component 600 is connected to the frame 100 and is located at the rear end of the dust sticking component to detect the thickness of the PC film. It can be understood that the frame 100, as the basic supporting structure of the entire device, is made of steel or other solid materials to ensure stability and durability. The static elimination component 200 includes but is not limited to an ion blower or similar static elimination equipment, which is installed at an appropriate position of the frame 100 and neutralizes the static electricity on the PC film by blowing out airflow with positive and negative ions. The dust-adhesive component is located at the rear end of the static elimination component 200, and includes a dust-adhesive roller 300 and a pressure roller 400. The surface of the dust-adhesive roller 300 is covered with a sticky material, such as silicone or rubber, to absorb dust on the PC film. The pressure roller 400 ensures that the PC film is closely attached to the dust-adhesive roller 300 through a spring or other pressure adjustment mechanism, thereby improving the dust removal effect. The dust-adhesive roller 300 is connected to the frame 100 through a lifting component 500, and the distance between the dust-adhesive roller 300 and the pressure roller 400 can be adjusted as needed. The thickness detection component 600 is located at the rear end of the dust-adhesive component, and can use laser ranging, ultrasonic ranging or other non-contact measurement technology to calculate the thickness of the PC film by measuring the distance between the PC film and the measuring head. The component has high-precision measurement capability and fast response speed to ensure the accuracy of the measurement results. By eliminating static electricity and dust on the PC film, interference of these factors on the thickness measurement result is avoided, thereby improving the measurement accuracy. On the other hand, static electricity and dust may damage the thickness detection component 600 or affect its normal operation. By eliminating these factors, the present device effectively protects the measuring equipment. By improving the measurement accuracy and protecting the measuring equipment, the cost loss caused by measurement errors and equipment damage is reduced. At the same time, the automated processing also reduces labor costs.

[0024] Reference Figure 2The specific implementation of the lifting assembly 500 includes a bracket 510 and a lifting frame 520 slidably connected to the bracket 510. The lifting frame 520 is moved up and down by connecting a driving member 540 (such as a motor, a cylinder, etc.). The driving member 540 is located at the bottom of the frame 100, and drives the lifting frame 520 and the sticky roller 300 installed thereon to rise and fall through mechanical transmission or pneumatic transmission, so as to adjust the distance between the lifting frame 520 and the pressure roller 400. Further, the lifting frame 520 is provided with two lifting arms 530, which are respectively located on both sides of the sticky roller 300, for firmly supporting the sticky roller 300. The design of the lifting arm 530 can ensure that the sticky roller 300 remains horizontal during the lifting process to avoid tilting or shaking. The lifting assembly 500 allows the distance between the sticky roller 300 and the pressure roller 400 to be flexibly adjusted as needed to adapt to PC films of different thicknesses and materials, thereby improving the versatility and adaptability of the device.

[0025] Reference Figure 1 and Figure 2 , there are two dust sticking components, one of which is located near the static elimination component 200 as the first dust sticking component 110, and the other side is the second dust sticking component 120. The dust sticking roller 300 of the first dust sticking component 110 is located at the top, and the dust sticking roller 300 of the second dust sticking component 120 is located at the bottom, so as to adhere to the upper and lower surfaces of the PC film respectively, so as to ensure that the upper and lower surfaces of the PC film are effectively dusted. Specifically, a boss is provided on the frame 100, and the second dust sticking component 120 is connected to the boss, so that the position of the second dust sticking component 120 is higher than the first dust sticking component 110. To ensure that the PC film forms a certain tension when passing through the two dust sticking components, which is conducive to improving the dust removal effect. By setting up two dust-sticking components, the upper and lower surfaces of the PC film can be dusted at the same time, thereby improving the dust removal effect and efficiency. The height difference between the first dust-sticking component 110 and the second dust-sticking component 120 is achieved through the boss to ensure that while adhering to the two surfaces of the PC film, the tension of the PC film can be adjusted to ensure that it forms stable contact and effective dust removal effect when passing through the dust-sticking component.

[0026] Reference Figure 2 Furthermore, a limiting groove 531 is provided at the top of the lifting arm 530, and the top of the limiting groove 531 is open, which is used to limit the sticky roller 300. When the sticky roller 300 is installed on the lifting arm 530, its shaft 310 will be stuck in the limiting groove 531, thereby ensuring the stability and accuracy of the sticky roller 300 during the lifting process.

[0027] Reference Figure 2Specifically, the sticky roller 300 is composed of a shaft 310, a rubber hose body 320 and a sticky paper 330. The shaft 310 is used as a supporting structure, and the rubber hose body 320 is mounted on the shaft 310 to increase the contact area with the PC film and improve the dust removal effect. The sticky paper 330 is wrapped outside the rubber hose body 320 to absorb dust. The sticky roller 300 adopts a replaceable sticky paper 330 design. When the sticky material on the sticky paper 330 is consumed or seriously contaminated, a new sticky paper 330 can be easily replaced to reduce maintenance costs and operating difficulties.

[0028] It should be noted that in some examples, the thickness detection component 600 uses an x-ray online thickness gauge. The x-ray online thickness gauge has the characteristics of high precision, high speed and non-contact measurement, and can measure the thickness of the PC film in real time, and output the data to the control system for processing and analysis. The application of the x-ray online thickness gauge enables the device to have high-precision and high-speed thickness measurement capabilities, which can meet the measurement requirements of strict requirements for the thickness of the PC film. The entire device realizes automated processing and measurement, reduces the need for manual intervention, and reduces labor costs.

[0029] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
