Description

Technical Field

[0001] The utility model relates to the technical field of dust sticking devices, in particular to a dust sticking device for PET films. Background Art

[0002] During the PET film production process, static electricity is generated, attracting large amounts of dust and impurities. This not only affects the film's quality and performance but also causes problems in subsequent processing. Dust collection effectively removes dust and impurities from the PET film surface, thereby preventing surface defects and improving surface quality. This is particularly important for products requiring high surface quality, such as optical and electronic films, which necessitates the use of a dust collection device for PET film.

[0003] The existing dust-sticking device controls the electrostatic sticky roller to fit with the PET film by passing the PET film between the guide roller and the electrostatic sticky roller. The PET film slides to drive the electrostatic sticky roller to roll. The sticky paper roller and the electrostatic sticky roller roll so that the dust adheres to the sticky paper roller. When the dust accumulates on the surface of the sticky paper roller, the sticky paper on the surface can be torn off. However, the installation and disassembly of the sticky paper roller is usually troublesome, which affects the operating efficiency and increases the working time. After searching, it was found that the technical solution provided by the utility model with application number CN202120928046.5 also has the above-mentioned problems. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and to provide a dust sticking device for PET film, wherein the two ends of the dust sticking paper roller are inserted into the sleeve ring, and the mounting block is inserted into the interior of the connecting block. At this time, the end of the latch squeezes the inclined surface of the card block, so that the card block moves to one end on both sides. When the card slot is against the card block, the card block loses the squeezing, and the first spring drives the card block to be inserted into the card slot, so that the mounting seat is fixed in the connecting block. When disassembly is required, the pull rod is pulled, and the pull rod drives the card block to slide, so that the latch loses the restriction of the card block, and the second spring loses the restriction of the card block and drives the sliding plate to rise. The rising sliding plate drives the latch to rise, thereby facilitating the replacement of the dust sticking paper roller and improving work efficiency.

[0005] The utility model also provides a dust-binding device for PET film as described above, comprising a bracket, a first slide groove being provided inside the bracket, a first slider being slidably connected inside the first slide groove, a threaded rod being threadedly connected inside the first slider, a synchronous wheel being fixedly connected at the lower end of the threaded rod, an outer surface of the synchronous wheel being rollingly connected to a synchronous belt, a guide roller being rotatably connected to a side surface of the bracket, a connecting block being fixedly connected to a side surface of the connecting block, and an electrostatic dust-binding roller being rotatably connected to a side surface of the connecting block;

The sliding plate can be driven to rise by the rebound of the second spring, and the rising sliding plate pushes the latch, which can be used to prevent the spring from driving the card block to enter the card slot again after the pull rod is released, so as to facilitate disassembly by one person.

[0009] According to the dust-binding device for PET film, a nut is threadedly connected to the outer surface of the threaded rod, and a knob is fixedly connected to the upper end of the threaded rod.

[0010] According to the dust-sticking device for PET film, the outer surface of the threaded rod is rotatably connected to the bracket, and the lower surface of the synchronous wheel is slidably connected to the bracket.
