Description

Technical Field

[0001] This utility model relates to the field of PET cast film processing technology, specifically to a PET cast film production line with rapid correction effect. Background Technology

[0002] A PET cast film production line is a complete set of equipment used to produce polyethylene terephthalate (PET) cast film. It mainly involves a series of processes including heating and melting PET granules, extrusion, casting, cooling, traction, and winding to ultimately produce PET cast film. During processing, the film needs to be transferred and transported; therefore, it is necessary to prevent the PET cast film from shifting during use. This requires the use of a web-aligning mechanism to prevent this.

[0003] The prior art discloses a PET cast film production line with rapid correction effect, application number 202221182378.4. The production line includes a PET cast film production line body, with a base and a conveyor frame for transporting PET film sheets on the bottom of the body. This invention configures the conveyor frame of the PET cast film production line as two convex support plates and multiple rotatably connected transmission rollers. The transmission roller in the middle is designated as a correction roller. Two adjustable rings that can be adjusted synchronously and flexibly are designed on the correction roller. These rings are flexibly controlled by a rotating seat at one end of the correction roller, allowing the two adjusting rings to move or be fixed relative to the correction roller. This forms a correction groove between the two adjusting rings for correcting the PET film sheet transmission, thereby correcting the PET film sheet transported from the previous stage. The continuously corrected PET film sheet is then transported to the next stage, ensuring stable and accurate transmission of the PET film sheet and improving the problem of film misalignment during the transport process.

[0004] However, the existing technology still has the following shortcomings. First, when the above-mentioned device is in use, it uses two movable adjusting rings to ensure the transmission position of the PET cast film and prevent deviation. However, when the adjusting rings move, they will squeeze the PET cast film, causing wrinkles in the PET cast film and affecting the subsequent processing quality. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 The present invention provides the following technical solution: a PET cast film production line with rapid correction effect, including a production line mechanism 1, a detection mechanism 2 and a limiting mechanism 3, wherein the limiting mechanism 3 is movably connected to the top of the detection mechanism 2 and the detection mechanism 2 is fixedly connected to the top of the production line mechanism 1.

[0024] The limiting mechanism 3 includes a bearing unit and a transmission unit. The bearing unit is movably connected to the top of the detection mechanism 2, and the transmission unit is movably connected to the inside of the bearing unit.

[0025] The detection mechanism 2 consists of a transmission frame 201, a stepper motor 202, a threaded transmission rod 203, a detection frame 204, a slide rail 205, and an infrared rangefinder 206. The transmission frame 201 is fixedly connected to the top of the production line mechanism 1. The stepper motor 202 is fixedly connected to both ends of the transmission frame 201. The threaded transmission rod 203 is rotatably connected to the inside of the transmission frame 201. The detection frame 204 is fixedly connected to the side of the transmission frame 201. The slide rail 205 is fixedly connected to the top of the detection frame 204. The infrared rangefinder 206 is movably connected to the top of the slide rail 205, playing the main detection role. It can detect the transmission status of the PET cast film in real time and quickly respond and correct deviations when the PET cast film deviates.

[0026] The supporting unit consists of a sliding frame 301, a sliding groove 302, a threaded base plate 303, an electric telescopic rod 304, and a sliding plate 305. The sliding frame 301 is movably connected to the inside of the transmission frame 201. The sliding groove 302 is formed on the side of the sliding frame 301. The threaded base plate 303 is fixedly connected to the bottom of the sliding frame 301 and is threadedly connected to the threaded transmission rod 203, facilitating the left and right movement of the entire sliding frame 301 driven by the threaded transmission rod 203. This allows the first and second correction rollers 312 and 314 to correct any misalignment of the PET cast film. The electric telescopic rod 304 is fixedly connected to the inner top of the transmission frame 201, and the sliding plate 305 is fixedly connected to the bottom of the electric telescopic rod 304, serving as the main transmission element and assisting in correction. A slider is provided on the side of the 5, and the slider slides on the surface of the slide groove 302, which plays the main role of sliding guide, making it easy to clamp the PET cast film. The transmission unit consists of a first spring frame 311, a first correction roller 312, a second spring frame 313, and a second correction roller 314. The first spring frame 311 is fixedly connected to the top of the threaded base plate 303, and the first correction roller 312 is rotatably connected to the side of the first spring frame 311. The surfaces of the first correction roller 312 and the second correction roller 314 are covered with a rubber protective layer, which plays the role of protecting the PET cast film. The second spring frame 313 is fixedly connected to the bottom of the sliding plate 305, and the second correction roller 314 is rotatably connected to the side of the second spring frame 313, which plays the main role of clamping and transmitting the PET cast film.

[0027] During use, the PET cast film is transported on production line mechanism 1. Infrared rangefinder 206 in detection mechanism 2 monitors the film transport status in real time on slide rail 205. When the film deviates, the detection signal is transmitted to the system, and stepper motor 202 drives threaded transmission rod 203 to rotate, which drives sliding frame 301, which is threadedly connected to threaded base plate 303, to move left and right. At the same time, electric telescopic rod 304 extends and retracts, causing sliding plate 305 to slide along slide groove 302, changing the distance between first correction roller 312 and second correction roller 314 to clamp the film. Under the action of spring frame, first correction roller 312 and second correction roller 314 adapt to film thickness and surface rubber layer protects the film. By adjusting the position of the rollers, the deviated film is corrected back to the normal transport track, ensuring the continuous and stable operation of the production line.
