[0039] This embodiment relates to a film dust remover that can be opened and closed automatically, which is used to remove dust or other impurities on the surface of the film. Figure 1 and Figure 2 , including a dust collector body 100, the dust collector body 100 has a closed state and an unfolded state. When the dust collector body 100 is in the unfolded state, the film to be dusted can be transported to the opening and closing part of the dust collector body 100, and when the dust collector body 100 is in the closed state, the dust collector body 100 can remove dust or other impurities on the film transported to the opening and closing part of the dust collector body 100.

[0040] The dust collector body 100 includes a mounting plate 10, a first cavity 20 fixedly mounted on the mounting plate 10, a second cavity 30 rotatably mounted on the mounting plate 10, and a dust removal assembly 40 disposed in the first cavity 20 and the second cavity 30, wherein the mounting plate 10 is vertically arranged, the first cavity 20 is arranged along a length direction perpendicular to the mounting plate 10, one end of the first cavity 20 is fixedly connected to the side wall of the mounting plate 10, and a first accommodating cavity 21 with a top opening is opened inside the first cavity 20; the second cavity 30 is located above the first cavity 20, and the second cavity 30 One end is rotatably connected to the side wall of the mounting plate 10, and a second accommodating chamber 31 with a bottom opening is opened inside the second cavity 30, and the second cavity 30 can rotate relative to the mounting plate 10 in a direction close to or away from the first cavity 20, so that the dust collector body 100 can freely switch between a closed state and an expanded state, and when the second cavity 30 rotates relative to the mounting plate 10 in a direction close to the first cavity 20 until it is parallel to the first cavity 20, the dust collector body 100 is in a closed state, and at this time, the openings of the first accommodating chamber 21 and the second accommodating chamber 31 are arranged relative to each other.

[0041] The dust removal assembly 40 includes two first dust sticking rollers 41 and two second dust sticking rollers 42, and the two first dust sticking rollers 41 and the two second dust sticking rollers 42 are respectively rotatably connected in the first cavity 20, that is, one of the first dust sticking rollers 41 and one of the second dust sticking rollers 42 are rotatably arranged in the first cavity 20, and the other first dust sticking roller 41 and the other second dust sticking roller 42 are rotatably arranged in the second cavity 30. When the dust removal machine body 100 is in a closed state, the two first dust sticking rollers 41 are arranged opposite to each other, and the two first dust sticking rollers 41 cooperate to form a gap for the dust removal film to pass through. The two second dust sticking rollers 42 are tangent to the outer circumferential surfaces of the two first dust sticking rollers 41, respectively, and the adhesion of the second dust sticking rollers 42 is greater than the adhesion of the first dust sticking rollers 41, and the first dust sticking roller 41 is used to absorb dust on the dust removal film, and the second dust sticking roller 42 is used to absorb dust on the first dust sticking roller 41.

[0042] It should be noted that, in the present embodiment, the first sticky roller 41 is a roller body having an adhesive force on its surface, and the second sticky roller 42 includes a rotating shaft and a coiled material sleeved on the rotating shaft, the coiled material also has adhesive force, and the adhesive force of the coiled material is greater than the adhesive force of the first sticky roller 41. Through the above arrangement, when the second sticky roller 42 absorbs more dust from the first sticky roller 41, it can continue to be used by tearing off the part of the coiled material with dust adhered to it.

[0043] When in use, first drive the second cavity 30 to rotate relative to the mounting plate 10 in a direction away from the first cavity 20, so that the dust remover body 100 is in an unfolded state. At this time, the film to be dusted is placed in the opening of the first cavity 20, and then the second cavity 30 is driven to rotate relative to the mounting plate 10 in a direction close to the first cavity 20 until it is parallel to the first cavity 20, so that the two first dust-sticking rollers 41 respectively arranged in the first cavity 20 and the second cavity 30 are respectively in contact with the upper and lower sides of the film, thereby realizing the dust on the surface of the film to be dusted. Finally, the two second dust-sticking rollers 42 respectively adsorb the dust on the two first dust-sticking rollers 41 to realize the transfer of dust, so that the two first dust removal rollers can continue to adsorb the dust on the surface of the film to be dusted.

[0044] Further, refer to Figure 3 , Figure 4 and Figure 5 The dust collector body 100 also includes a locking mechanism 50 for locking the closed state of the dust collector body 100 so that the dust collector body 100 can be stably in the closed state.

[0045] The locking mechanism 50 includes a first fixing block 51 fixed in the first cavity 20, a second fixing block 52 fixed in the second cavity 30, a first vertical groove 53 and a second vertical groove 54 respectively provided on the first fixing block 51 and the second fixing block 52, a locking rod 55 provided at the notch of the first vertical groove 53, and a locking block 56 for cooperating with the locking rod 55, wherein the first fixing block 51 and the second fixing block 52 are respectively located at one end of the first cavity 20 and the second cavity 30 away from the mounting plate 10, and the first fixing block 51 and the second fixing block 52 are arranged opposite to each other; the first vertical groove 53 is located at the first fixing block 51 and the second fixing block 52 are located at the first fixing block 51 and the second fixing block 52 are located at the first fixing block 51 and the second fixing block 52 are arranged opposite to each other; the first vertical groove 53 is located at the first fixing block 51 and the second fixing block 52 are located at the first fixing block 51 and the second fixing block 52 are located at the first fixing block 51 and the second fixing block 52 are located opposite to each other; the first vertical groove 53 is ... opposite to each other; the first vertical groove 53 is located at the first fixing The block 51 is on the side away from the mounting plate 10, the second vertical groove 54 is located on the side of the second fixing block 52 away from the mounting plate 10, and the first vertical groove 53 and the second vertical groove 54 are both vertically arranged; the locking rod 55 is arranged along the length direction perpendicular to the second vertical groove 54, and the length of the locking rod 55 is longer than the width of the second vertical groove 54; one end of the locking block 56 is rotatably connected to the first vertical groove 53, and the other end of the locking block 56 is located in the second vertical groove 54 and can be rotated toward the inside of the second vertical groove 54, and the end of the locking block 56 located in the second vertical groove 54 is provided with a hooking portion 561 for hooking and cooperating with the locking rod 55.

[0046] In addition, the opening of the hooking portion 561 faces the locking rod 55, and a guiding slope 562 is provided on the top of the hooking portion 561, so that when the second cavity 30 rotates toward the direction close to the first cavity 20, the locking rod 55 can automatically cooperate with the locking block 56 to lock under the action of the guiding slope 562, thereby realizing the locking of the closed state of the dust collector body 100, that is, the dust collector body 100 can be stably in the closed state.

[0047] Furthermore, an unlocking button 57 is disposed on a side of the locking block 56 facing away from the second fixing block 52 , and a button hole for the unlocking button 57 to extend out is disposed on the first cavity 20 .

[0048] It can be understood that by driving the second cavity 30 to rotate relative to the mounting plate 10 in a direction close to the first cavity 20 until it is parallel to the first cavity 20, the locking rod 55 provided in the second cavity 30 can automatically cooperate with the locking block 56 in the first cavity 20 to lock, so that the dust collector body 100 is switched from the expanded state to the closed state and is stably in the closed state. When the dust collector body 100 needs to be switched from the closed state to the expanded state, by pressing the unlocking button 57, the locking block 56 is driven to move toward the inside of the first vertical groove 53, so that the locking block 56 is separated from the locking rod 55, thereby realizing the unlocking of the closed state of the dust collector body 100. At this time, the dust collector can be switched from the closed state to the expanded state by driving the second cavity 30 to rotate relative to the mounting plate 10 in a direction away from the first cavity 20.

[0049] Furthermore, the dust collector body 100 also includes a driving mechanism 60 for driving the second cavity 30 to rotate relative to the mounting plate 10 toward or away from the first cavity 20, so that the dust collector body 100 can automatically switch from a closed state to an expanded state.

[0050] In this embodiment, there are two groups of driving mechanisms 60, both of which are located in the second cavity 30, and the two groups of driving mechanisms 60 are symmetrically arranged on both sides of the second cavity 30, and the two groups of driving mechanisms 60 cooperate to drive the second cavity 30 to rotate stably relative to the mounting plate 10 toward or away from the first cavity 20.

[0051] The driving mechanism 60 includes a fixing seat 61 fixed in the second cavity 30 and a gas spring 62 rotatably arranged in the second cavity 30, wherein the fixing seat 61 is fixedly installed on one side of the middle part of the second cavity 30 close to the mounting plate 10, one end of the gas spring 62 is rotatably connected to the fixing seat 61, and the other end of the gas spring 62 passes through the second cavity 30 and is rotatably connected to the mounting plate 10.

[0052] It can be understood that when the unlocking button 57 contacts the lock of the closed state of the dust collector body 100, the gas spring 62 is driven to expand and contract, thereby driving the second cavity 30 to rotate relative to the mounting plate 10 in a direction closer to or away from the first cavity 20, so that the dust collector body 100 can automatically switch between the expanded state and the closed state.

[0053] Further, refer to Figure 1 , Figure 2 and Figure 6A pull-out opening 22 is provided at one end of the first cavity 20 and the second cavity 30 away from the mounting plate 10. The two pull-out openings 22 are respectively connected to the first accommodating cavity 21 and the second accommodating cavity 31.

Both pull-out cabinets 70 can be pulled out from the pull-out opening 22, and two second dust-sticking rollers 42 are respectively rotatably provided in the two pull-out cabinets 70.

[0054] It can be understood that by arranging the second sticky roller 42 in the pull-out cabinet 70 and being able to pull it out from the pull-out opening 22, when the second sticky roller 42 adheres to a lot of dust from the first sticky roller 41, the dust on the second sticky roller 42 can be processed by pulling out the pull-out cabinet 70 (just tear off the part of the roll material with dust adhered to it), so that the second sticky roller 42 can continue to absorb the dust on the first sticky roller 41.

[0055] Further, a handle 71 is provided at one end of the drawer cabinet 70 away from the mounting plate 10. By providing the handle 71, the drawer cabinet 70 can be conveniently pulled out.

[0056] Furthermore, both the first cavity 20 and the second cavity 30 are provided with observation ports 23 , which are located on the side walls of the first cavity 20 and the second cavity 30 , and transparent plates are provided at the observation ports 23 .

[0057] By providing the observation port 23 and the transparent plate, people can see the internal situation through the observation port 23, that is, observe the dust adsorption degree on the surface of the second dust-adhesive roller 42, so that people can tear off or replace the roll material conveniently.
