Description

Technical Field

[0001] The utility model relates to the technical field of thin film dust removal, in particular to a thin film dust removal device. Background Art

[0002] Film dust remover is a device used to remove dust and other impurities from the surface of film. It is widely used in the production process of plastic film, paper, metal foil and other materials.

[0003] In the related art, CN205413704U discloses a film online dust removal device, including a first dust sticking roller and a second dust sticking roller, wherein the first dust sticking roller has two and is symmetrically arranged in parallel on both sides of the film to be dusted, the gap between the two first dust sticking rollers corresponds to the thickness of the film to be dusted, and the first dust sticking roller is used to adhere to the dust on the surface of the film to be dusted; the second dust sticking roller has two and is tangent to the outer circumferential surface of the two first dust sticking rollers, respectively, and the second dust sticking roller is used to adhere to the dust on the first dust sticking roller; wherein the adhesion of the second dust sticking roller is higher than the adhesion of the first dust sticking roller. When in use, by setting the first dust sticking roller and the second dust sticking roller with different adhesion, the dust on the surface of the film is first adhered by the first dust sticking roller, and then the dust adhered by the first dust sticking roller is adhered by the second dust sticking roller, so that the first dust sticking roller can be repeatedly used, which is convenient for later maintenance and care.

[0004] However, although CN205413704U removes dust on the surface of the film through the cooperation of the first sticky roller and the second sticky roller, the distance between the second sticky roller and the first sticky roller is not adjustable, and the second sticky roller cannot continuously press against the outer circumferential surface of the first sticky roller, making it difficult for the dust on the first sticky roller to be completely transferred to the second sticky roller, affecting the dust removal effect of the first sticky roller on the film, and after a period of use, the first sticky roller and the second sticky roller with adhesion need to be replaced with new ones, which increases the dust removal cost.

DETAILED DESCRIPTION

[0047] The following will be combined with the attached embodiment of the present utility model Figure 1-6 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0048] It should be noted that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", "back", "side", "circumferential" and the like in the present invention indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as a limitation on the present invention. In addition, the words "first", "second" and the like are only used to distinguish multiple components or structures with the same or similar structures, and do not represent any special limitation on the setting order or connection relationship.

[0049] This embodiment relates to a film dust removal device for removing dust or other impurities on the film. Figure 1-Figure 6 , including a support plate 10, a first cavity 20, a second cavity 30, a first dust sticking mechanism 40, a second dust sticking mechanism 50 and a tightening mechanism 60, wherein the support plate 10 is vertically arranged, the first cavity 20 is arranged along a length direction perpendicular to the support plate 10, one end of the first cavity 20 is fixedly connected to the side wall of the support plate 10, and the first cavity 20 has a first accommodating cavity with a top opening; the second cavity 30 has the same shape and structure as the first cavity 20, the second cavity 30 is located above the first cavity 20, one end of the second cavity 30 is rotatably connected to the support plate 10, the second cavity 30 has a second accommodating cavity with a bottom opening, and when the second cavity 30 rotates relative to the support plate 10 to be parallel to the first cavity 20, the first cavity 20 and the second cavity 30 are arranged opposite to each other.

[0050] The first dust-sticking mechanism 40 includes two dust-sticking rollers 41 which are rotatably disposed in the first cavity 20 and the second cavity 30 respectively. The two dust-sticking rollers 41 are symmetrically disposed at the openings of the first accommodating cavity and the second accommodating cavity. When the second cavity 30 rotates relative to the bracket to be parallel to the first cavity 20, the two dust-sticking rollers 41 cooperate to form a gap for the film to be dust-removed to pass through, and the two dust-sticking rollers 41 cooperate to adsorb dust on the upper and lower sides of the film.

[0051] The second dust sticking mechanism 50 includes two mounting frames 51 respectively arranged in the first cavity 20 and the second cavity 30 and two paper rolls 52 respectively rotatably arranged on the two mounting frames 51, and the two ends of the paper rolls 52 are respectively rotatably connected to the two ends of the mounting frames 51. The two paper rolls 52 are respectively used to be tangent to the outer circumferential surfaces of the two dust sticking rollers 41. The adhesion force on the paper roll 52 is greater than the adhesion force on the dust sticking roller 41, so that the paper roll 52 can absorb dust on the dust sticking roller 41.

[0052] There are two groups of pressing mechanisms 60, which are respectively arranged in the first cavity 20 and the second cavity 30. The two groups of pressing mechanisms 60 are symmetrically arranged, and are respectively used to drive the two paper rolls 52 to move toward or away from the sticky roller 41, so that the two paper rolls 52 can touch the surface of the two sticky rollers 41 or separate from the two sticky rollers 41.

[0053] It can be understood that when in use, the film to be dusted is passed through the gap formed by the two dust-sticking rollers 41, and the dust on the film is adsorbed by the two dust-sticking rollers 41, so that the dust on the film is adsorbed onto the two dust-sticking rollers 41. At this time, the two paper rolls 52 are driven by the pressing mechanism 60 to move respectively in the direction close to the two dust-sticking rollers 41, so that the two paper rolls 52 can be pressed against the outer circumferential surface of the two dust-sticking rollers 41 respectively. At this time, the adhesion force on the two paper rolls 52 is greater than the adhesion force on the two dust-sticking rollers 41, so that the dust on the two dust-sticking rollers 41 can be adsorbed onto the two paper rolls 52, thereby realizing the transfer of dust, making the two dust-sticking rollers 41 reusable, and further making the two dust-sticking rollers 41 able to continuously adsorb the dust on the film, thereby ensuring the dust removal effect on the film. When the two paper rolls 52 absorb a lot of dust, the pressing mechanism 60 drives the paper rolls 52 to move away from the dust sticking roller 41, so that the paper rolls 52 are separated from the dust sticking roller 41, thereby facilitating the tearing off of the dust-adhered parts of the paper rolls 52 or replacing them with new ones. The operation is simple and convenient, and the dust removal cost is effectively reduced.

[0054] Furthermore, the clamping mechanism 60 includes two sliders 61, two groups of driving components 62 and two groups of elastic components 63, wherein the two sliders are slidably arranged at the two ends of the mounting frame 51 respectively, and the end of the mounting frame 51 is provided with a vertical groove for slidingly cooperating with the slider 61, and the paper roll 52 is located on the inner side of the mounting frame 51, and a rotating shaft is passed through the paper roll 52, and the two ends of the rotating shaft pass through the two vertical grooves and are respectively fixedly connected to the two sliders 61.

[0055] It should be noted that, in this embodiment, the mounting frame 51 is roughly U-shaped. When the second cavity 30 is parallel to the first cavity 20, the openings of the two mounting frames 51 are opposite to each other, and both ends of the mounting frames 51 extend outward to form a accommodating space for accommodating the clamping mechanism 60.

[0056] The two sets of driving components 62 are symmetrically arranged at both ends of the mounting frame 51 , corresponding to the two sliders 61 one by one, and are used to drive the sliders 61 to slide downward along the length direction of the vertical groove to drive the paper roll 52 to move toward or away from the dust sticking roller 41 .

[0057] Two sets of elastic components 63 are symmetrically arranged at both ends of the mounting frame 51, corresponding one to one with the two sliders 61, and are used to provide elastic force to the paper roll 52 when the paper roll 52 abuts against the sticky roller 41 so that the paper roll 52 is pressed tightly against the sticky roller 41, and to provide pulling force to the paper roll 52 when the paper roll 52 is separated from the sticky roller 41 so that the paper roll 52 is automatically reset.

[0058] It can be understood that when removing dust, the driving component 62 drives the slider 61 to slide upward along the length direction of the vertical groove, driving the paper roll 52 to move in the direction close to the dust sticking roller 41 and abut against the dust sticking roller 41. At this time, the elastic component 63 provides elastic force to the paper roll 52, so that the paper roll 52 can be pressed against the outer circumferential surface of the dust sticking roller 41, thereby ensuring the adsorption effect of the paper roll 52 on the dust sticking roller 41, so that the dust on the dust sticking roller 41 can be more thoroughly adsorbed by the paper roll 52, that is, the dust sticking roller 41 can stably adsorb the dust on the film, thereby improving the dust removal effect. At the same time, when not removing dust, the driving component 62 drives the slider 61 to slide, so that the paper roll 52 moves away from the dust sticking roller 41 and separates from the dust sticking roller 41. At this time, the elastic component 63 can provide pulling force to the paper roll 52, so that the paper roll 52 can be stably separated from the dust sticking roller 41, so as to facilitate the tearing or replacement operation of the paper roll 52.

[0059] Further, the driving assembly 62 includes two guide rods 621, a lifting block 622, a connecting rod 623 and a driving cylinder 624, wherein the two guide rods 621 are vertically mounted on the ends of the mounting frame 51 (i.e., in the accommodating area formed by the two ends of the mounting frame 51 extending outward), the two guide rods 621 are symmetrically arranged on both sides of the slider 61, and both ends of the two guide rods 621 are fixedly connected to the upper and lower sides of the ends of the mounting frame 51. The lifting block 622 is located above the slider 61, and a through hole for two guide posts to pass through is opened on its surface, and the lifting block 622 can slide up and down relative to the guide rods 621. The connecting rod 623 is arranged on the lifting block 622, one end of which passes through the lifting block 622 and is fixedly connected to the slider 61, and the other end has a convex ring that contacts the surface of the lifting block 622, so that the connection between the lifting block 622 and the slider 61 can be achieved through the connecting rod 623. The driving cylinder 624 is fixedly mounted on the end of the mounting frame 51 . The driving cylinder 624 is arranged along a length direction perpendicular to the mounting frame 51 . The piston rod of the driving cylinder 624 passes through the mounting frame 51 and is fixedly connected to the lifting block 622 .

[0060] It can be understood that by causing the piston rod of the driving cylinder 624 to retract or extend, the lifting block 622 is driven to slide downward along the length direction of the guide rod 621, thereby driving the slider 61 to slide up and down, that is, driving the paper roll 52 to move toward or away from the dust-sticking roller 41.

[0061] In addition, in this embodiment, a controller 625 for controlling the extension and retraction of the piston rod of the driving cylinder 624 is also provided on the outside of the second cavity 30. The controller 625 has a toggle switch. By toggling the toggle switch toward or away from the mounting plate, the piston rod of the driving cylinder 624 can be extended or retracted.

[0062] Furthermore, the elastic component 63 includes two first springs 631 and a second spring 632. The two first springs 631 are respectively sleeved on the two guide rods 621. The two ends of the two first springs 631 are respectively abutted against the lifting block 622 and the mounting frame 51. The second spring 632 is sleeved on the connecting rod 623. The two ends thereof are respectively abutted against the lifting block 622 and the slider 61. When the paper roll 52 is driven to move toward the direction close to the sticky roller 41 and contact the sticky roller 41, the first spring 631 and the second spring 632 are both compressed. At this time, the first spring 631 and the second spring 632 both provide elastic force to the lifting block 622, that is, provide elastic force to the slider 61, so that the paper roll 52 can be stably pressed against the sticky roller 41. At the same time, when the paper roll 52 is driven to move in a direction away from the sticky roller 41 and separate from the sticky roller 41, the first spring 631 and the second spring 632 are automatically restored, thereby generating a pulling force on the lifting block 622, that is, generating a pulling force on the slider 61, so that the paper roll 52 can be stably separated from the sticky roller 41.

[0063] Furthermore, the clamping mechanism 60 also includes a limiting ring 64 and an abutting ring 65. The limiting ring 64 is fixedly mounted on the guide rod 621, and is used to limit the sliding position of the lifting block 622. The abutting ring 65 is mounted on the guide rod 621, and is symmetrically arranged on the upper and lower sides of the lifting block 622 with the limiting ring 64. The abutting ring 65 is fixedly connected to the lifting block 622, and is used to abut and cooperate with the first spring 631.

[0064] It can be understood that the sliding position of the lifting block 622 is limited by the limiting ring 64, so that the lifting block 622 can slide up and down within the set area, so that the contact or separation between the paper roll 52 and the dust-sticking roller 41 can be achieved after the stroke of the driving cylinder 624 is adjusted accordingly, making the structure compact and reducing space. Through the abutment cooperation between the abutment ring 65 and the first spring 631, it can effectively avoid the first spring 631 from damaging the surface of the lifting block 622.

[0065] Furthermore, the bracket is provided with an automatic opening and closing mechanism 70 for driving the second cavity 30 to rotate relative to the bracket toward or away from the first cavity 20 so that the second cavity 30 can automatically rotate relative to the bracket to be parallel to the first cavity 20 .

[0066] In this embodiment, there are two groups of automatic opening and closing mechanisms 70 , which are symmetrically arranged on both sides of the second cavity 30 , and the two groups of automatic opening and closing mechanisms 70 cooperate to drive the second cavity 30 to rotate stably relative to the first cavity 20 .

[0067] Specifically, the automatic opening and closing mechanism 70 includes a mounting seat and a gas spring 72 , wherein the mounting frame 51 is fixedly disposed in the second cavity 30 , one end of the gas spring 72 is rotatably connected to the bracket, and the other end extends into the second cavity 30 and is rotatably connected to the fixed seat 71 .

[0068] It should be noted that, in the present embodiment, the second cavity 30 is rotatably connected to the support plate 10 by means of hinges, hinges or rotating shafts, and the rotating end thereof is located on the upper side of the end of the second cavity 30, so that when the second cavity 30 is rotated to be parallel to the first cavity 20, the second cavity 30 and the first cavity 20 are symmetrically arranged.

[0069] By driving the gas spring 72 to expand or contract, the second cavity 30 is driven to automatically rotate relative to the bracket to be parallel to the first cavity 20, thereby realizing the automatic opening and closing of the second cavity 30. When removing dust, the film to be removed is first placed at the opening of the first cavity 20, so that the film contacts the dust sticking roller 41 at the opening of the first cavity 20, and then the gas spring 72 drives the second cavity 30 to rotate in the direction close to the first cavity 20 and parallel to the first cavity 20, so that the dust disposed in the first cavity 20 and the second cavity 30 can respectively abut against the surface of the film, thereby facilitating the adsorption of dust on the film.

[0070] Furthermore, a static electricity removal mechanism 31 is provided in the second cavity 30 , and the static electricity removal mechanism 31 is used to remove static electricity on the film to be dusted. In this embodiment, there are two static electricity removal mechanisms 31 , and the two static electricity removal mechanisms 31 are symmetrically arranged on both sides of the paper roll 52 .

[0071] Furthermore, a drawer opening 32 is provided on the first cavity 20 and the second cavity 30, and a slide rail 33 for slidingly cooperating with the mounting frame 51 is provided in the first cavity 20 and the second cavity 30, and a cabinet door 511 adapted to the drawer opening 32 is provided on one side of the two mounting frames 51 close to the drawer opening 32.

[0072] Furthermore, the cabinet door 511 is provided with a handle 512 for easy pulling.

[0073] It can be understood that, through the provision of the drawer opening 32 , the cabinet door 511 and the handle 512 , the mounting frame 51 and the paper roll 52 can be pulled out together, thereby facilitating the tearing off or replacement of the paper roll 52 .

[0074] The above is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
