Description

Technical Field

[0001] This utility model relates to the field of plastic film production technology, and specifically to a plastic film crack detection device. Background Technology

[0002] Plastic film is a common household item. Its advantages, including good transparency, good moisture barrier properties, excellent heat resistance, ease of use, and low cost, make it widely used in various industries. Biaxial stretching has always been a relatively advanced plastic film production process, producing films with thinner profiles and superior performance. In particular, with economic development, more and more fields require high-strength, high-insulation optical-grade plastic films or ultra-thin plastic films, which can generally only be manufactured using the biaxial stretching process.

[0003] In actual production, plastic film is prone to cracking due to overstretching, leading to defective products and reducing the yield rate. Furthermore, these cracked films fail to meet customer requirements, resulting in significant rework and wasted labor if sent to customers.

[0004] When using existing plastic film crack detection devices, wrinkles easily appear on the film surface, and cracks may exist in the wrinkled areas, which are not easily observed by staff and affect the detection work. Utility Model Content

[0005] The purpose of this invention is to provide a plastic film crack detection device to overcome the shortcomings of the above-mentioned technology.

[0006] To achieve the above objectives, this utility model provides a plastic film crack detection device, including a detection platform. Clamping guide rollers are provided on the left and right sides of the top surface of the detection platform. Slide rails are provided on the front and rear sides of the detection platform, and sliders slide on the slide rails. A bearing plate is provided on the slider, and a lifting plate is connected to the bearing plate via a push rod. A bearing seat is provided on the lifting plate. A leveling roller and a leveling roller 2 are provided on the upper side of the detection platform, with the leveling roller 2 located directly above the leveling roller 1. The two ends of the rotating shaft of the leveling roller 1 are respectively connected to two bearing seats. A column is provided on the lifting plate, and a cavity is provided inside the column. A telescopic rod is provided inside the cavity, moving downwards. A moving block is provided inside the cavity, with its side fitting against the inner wall of the cavity. A bearing seat 2 is provided at the bottom of the moving block. A through-channel communicating with the cavity is provided on the column. The two ends of the rotating shaft of the leveling roller 2 pass through the through-channels on both sides and are connected to the bearing seats. A connecting plate is provided between the two lifting plates, and a lamp is provided on the connecting plate.

[0007] Preferably, the bottom of the testing platform is provided with a support frame.

[0008] Preferably, the testing platform is equipped with a control panel, which is communicatively connected to the slide rail, push rod, telescopic rod, and lamps.

[0009] The beneficial effects of this utility model are as follows: The plastic film to be tested is passed sequentially between the clamping guide roller on one side, the leveling roller one and the leveling roller two, and the clamping guide roller on the other side. The position of the lifting plate is adjusted by the push rod so that the surface of the leveling roller one is against the bottom surface of the plastic film. Then, the position of the moving block is adjusted by the telescopic rod so that the surface of the leveling roller two is against the top surface of the plastic film, thereby achieving the clamping of the plastic film by the leveling roller one and the leveling roller two. The leveling roller one and the leveling roller two are driven to reciprocate through two slide rails, which can achieve the leveling effect of the plastic film during the conveying of the plastic film. With the help of lighting, it can facilitate the observation and detection of cracks by the staff. Attached Figure Description
