Description

Technical Field

[0001] This utility model relates to the field of plastic film production technology, and in particular to a cleaning device for plastic film production. Background Technology

[0002] The light transmittance of plastic film used in agricultural greenhouses directly affects crop photosynthetic efficiency and yield. Generally, the light transmittance requirement for plastic film used in agricultural greenhouses is ≥85%, with high-end products requiring >90%. During the production process, dust and other impurities easily accumulate on the surface of the plastic film, which affects its light transmittance and prevents it from meeting the requirements for light transmittance in agricultural greenhouses. Therefore, cleaning devices are needed to remove dust and other impurities from the film surface to ensure the light transmittance of the plastic film.

[0003] Traditional cleaning devices used in plastic film production have been found to have shortcomings. They cannot perform zoned inspection of the plastic film, and when the light transmittance of a corresponding zone is found to be substandard, they cannot perform timely and efficient cleaning. This results in high cleaning costs and makes them unsuitable for industrial-scale mass production. Therefore, it is necessary to optimize and improve traditional cleaning devices used in plastic film production. Summary of the Invention

[0004] The purpose of this invention is to overcome the aforementioned problems in traditional technologies and provide a cleaning device for plastic film production.

[0005] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution: A cleaning device for plastic film production, comprising: A front-mounted transmittance detection component is disposed at the front of the plastic film traction surface. The front-mounted transmittance detection component includes a first frame, and a plurality of first split-type transmittance detectors are arranged side by side along the width direction of the plastic film. The cleaning component is located in the middle of the plastic film traction surface. The cleaning component includes a second frame, and two rows of vacuum cleaning units are symmetrically installed on the upper and lower frame plates of the second frame. The positions of the vacuum cleaning units are matched with the positions of the corresponding first split light transmittance detectors. A rear transmittance verification component is provided, which is located at the rear of the plastic film traction surface. The rear transmittance verification component includes a third frame. An upper linear guide pair is installed on the upper frame plate of the third frame, and a lower linear guide pair is installed on the lower frame plate of the third frame.

[0006] Furthermore, the above-mentioned cleaning device for plastic film production also includes a light shield, which is sleeved on the outside of the front transmittance detection component, the cleaning component, and the rear transmittance verification component. The front and rear plates of the light shield are symmetrically provided with perforation holes to facilitate the passage of the plastic film.

[0007] Furthermore, in the cleaning device for producing plastic film, a row of first light source emitting units is evenly installed on the upper frame plate of the first frame, and a row of first light source receiving units is evenly installed on the lower frame plate of the first frame. The first light source emitting units and the first light source receiving units together constitute a first split-type transmittance detector.

[0008] Furthermore, in the cleaning device for producing plastic film described above, a second light source emitting unit is installed on the outside of the slider of the upper linear guide pair, and a second light source receiving unit is installed on the outside of the slider of the lower linear guide pair. The second light source emitting unit and the second light source receiving unit together constitute a second split-type transmittance detector.

[0009] Furthermore, in the aforementioned cleaning device for plastic film production, the dust extraction cleaning unit includes a suction pump, a lifting push rod, a support tube, an opening box, a suction hose, a partition, a positioning shaft, and rollers. The lifting push rod is installed on the upper or lower frame plate of the second frame. The movable end of the lifting push rod is connected to the opening box via the support tube.

[0012] Furthermore, in the aforementioned cleaning device for producing plastic film, a portion of the roller body protrudes outward relative to the opening surface of the opening box.

[0013] The beneficial effects of this utility model are: This utility model device is rationally designed, mainly consisting of a front-end transmittance detection component, a cleaning component, and a rear-end transmittance verification component, with each component working in concert. Multiple first-stage split-type transmittance detectors in the front-end transmittance detection component are used to perform zoned detection of the plastic film. When the first-stage split-type transmittance detector in a corresponding zone detects a transmittance lower than a set value, it is determined that dust or other impurities are present. The cleaning unit in the corresponding zone is then activated to remove dust and impurities from that zone. The second-stage split-type transmittance detector in the rear-end transmittance verification component is moved to the zone where the obstruction occurred to retest its transmittance, ensuring that the transmittance of the plastic film product meets the standard requirements. This also facilitates the detection of faulty cleaning units.

[0020] In this embodiment, the post-transmittance verification component 3 includes a third frame 301. An upper linear guide pair 302 is mounted on the upper frame plate of the third frame 301, and a lower linear guide pair 304 is mounted on the lower frame plate of the third frame 301. A second split-type transmittance detector is mounted on the outer side of the sliders of the upper linear guide pair 302 and the lower linear guide pair 304. A second light source emitting unit 303 is mounted on the outer side of the slider of the upper linear guide pair 302, and a second light source receiving unit 305 is mounted on the outer side of the slider of the lower linear guide pair 304.

Multiple first split-type transmittance detectors in the pre-transmittance detection component 1 are used to perform zoned detection on the plastic film 4. When the first split-type transmittance detector of the corresponding zone detects a transmittance lower than a set value, it is determined that dust or other impurities are present. The dust collection and cleaning unit of the corresponding zone in the cleaning component 2 is activated to remove dust and impurities from the corresponding zone. The second split-type transmittance detector in the post-transmittance verification component 3 is moved to the zone where the previous blockage occurred to retest its transmittance, ensuring that the transmittance of the plastic film 4 meets the standard requirements. This also facilitates the detection of faulty dust collection and cleaning units.
