[0017] The second aspect of the present invention provides a production method of a dust removal film, including the following steps:

[0018] (1) Pull the first protective film on the first protective film roller into the space between the film laminating roller and the film winding drum. Start the rotation of the film winding drum, and laminate and wind the first protective film onto the surface of the film winding drum through the film laminating roller. When the winding of the first protective film is completed, stop the rotation of the film winding drum and cut the tail end of the first protective film.

[0019] (2) Pull the dust removal film on the dust removal film roller into the space between the film laminating roller and the film winding drum.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0039] Please refer to Figure 2 and Figure 3 , an embodiment of the present invention provides a dust removal film production device with an automatic labeling function, including components such as a frame 1, a film winding drum 2, a drum rotation driving device 3, a film laminating roller 4, a roller advancing and retracting driving device 5, a dust removal film material roller 10, a first protective film material roller 11, a second protective film material roller 12, a film material cutting device 6, a labeling lifting driving device 7, a labeling position transverse movement device 8, a label laminating device 9, a photoelectric sensor 13, and a drum braking device 19. Each component of this embodiment will be described in detail below with reference to the accompanying drawings.

[0040] As Figure 2 and Figure 3 shown, the film winding drum 2 is arranged in a cylindrical shape. The film winding drum 2 is rotatably installed in the middle of the frame 1 through a drum rotating shaft 21. The drum rotation driving device 3 is in transmission connection with the film winding drum 2 and drives it to rotate 360 degrees.

[0041] Specifically, the drum rotation driving device 3 may include a drum rotation driving motor 31, a speed reducer 32, a drum rotation transmission wheel 33, and a drum rotation transmission belt 34. The drum rotation driving motor 31 is in transmission connection with the speed reducer 32. The drum rotation transmission wheels 33 are respectively installed at one end of the output shaft of the speed reducer 32 and the drum rotating shaft 21. The drum rotation transmission belt 34 is connected between the two drum rotation transmission wheels 33. The drum rotation driving motor 31 can drive the film winding drum 2 to rotate through the drum rotation transmission wheels 33 and the drum rotation transmission belt 34.

[0042] As Figure 4 and Figure 5As shown in the figure, the pressing roller advancing and retreating driving device 5 is installed at the top of both sides of the frame 1. Both ends of the film laminating pressing roller 4 are rotatably connected to the pressing roller advancing and retreating driving devices 5 on both sides respectively. The film laminating pressing roller 4 is located between the dust removing film material roller 10 and the film winding roller 2 and is close to the film winding roller 2. Among them, the pressing roller advancing and retreating driving device 5 may include a pressing roller advancing and retreating driving cylinder 51, a sliding seat 52 and an advancing and retreating slider 53. The pressing roller advancing and retreating driving cylinder 51 is installed at one end of the sliding seat 52. The pressing roller advancing and retreating driving cylinder 51 is connected to the advancing and retreating slider 53 inside the sliding seat 52. Both ends of the film laminating pressing roller 4 are respectively rotatably connected to the corresponding advancing and retreating sliders 53. The pressing roller advancing and retreating driving cylinder 51 can drive the film laminating pressing roller 4 connected to the advancing and retreating slider 53 to move horizontally (i.e., move forward and backward) in the direction close to or away from the film winding roller 2. When feeding the material, the film laminating pressing roller 4 can be far away from the film winding roller 2. When laminating the film, the film laminating pressing roller 4 needs to be abutted against the film winding roller 2.

[0043] As Figure 2 , Figure 4 and Figure 5 shown in the figure, three bosses 15 arranged in layers from top to bottom are respectively provided on both sides of the front end of the frame 1. Locking roller seats 16 are respectively provided at both ends of the dust removing film material roller 10, the first protective film material roller 11 and the second protective film material roller 12. The locking roller seats 16 are respectively installed on the corresponding bosses 15. A material roller accommodating groove is respectively opened at the front end of each locking roller seat 16. A locking roller screw 17 extending longitudinally into the material roller accommodating groove is provided at the top of the locking roller seat 16. Material roller bearings 18 are provided at both ends of the dust removing film material roller 10, the first protective film material roller 11 and the second protective film material roller 12. The lower end of the locking roller screw 17 can lock the outer rings of the material roller bearings 18 of the corresponding dust removing film material roller 10, the first protective film material roller 11 and the second protective film material roller 12. In this way, the dust removing film material roller 10, the first protective film material roller 11 and the second protective film material roller 12 are respectively rotatably installed at the front end of the frame 1.

[0044] When the film materials on the dust removing film material roller 10, the first protective film material roller 11 and the second protective film material roller 12 are used up, the locking roller screws 17 can be loosened. In this way, the dust removing film material roller 10, the first protective film material roller 11 and the second protective film material roller 12 can be quickly disassembled from the frame 1, which is convenient for the operator to set the new film materials on the corresponding material rollers.

[0045] As Figure 2 and Figure 3As shown, the film cutting device 6 is installed on the frame 1 through the bracket 14 and is located on top of the film winding roller 2. Specifically, the film cutting device 6 may include a cutter driving cylinder 61, a cutter driving swing arm 62, a cutter shaft 63, and at least one film cutting knife 64. Both ends of the cutter shaft 63 are installed on the bracket 14 through cutter shaft bearings 65. Two cutter driving cylinders 61 are provided and are respectively installed on the corresponding brackets 14. The output rods of the two cutter driving cylinders 61 are respectively connected to both ends of the cutter shaft 63 through the corresponding cutter driving swing arms 62. The film cutting knife 64 is installed on the cutter shaft 63. Among them, the film cutting knife 64 may correspond to the middle part of the film winding roller 2, so that the film material can be cut into two parts from the middle. Of course, the film cutting knife 64 may also be arranged at the positions close to both sides of the film winding roller 2, and the position of the film cutting knife 64 can be adjusted according to the size of the film material.

[0046] When film cutting is required, the cutter driving cylinder 61 can drive the film cutting knife 64 to turn downward through the cutter driving swing arm 62 to approach the surface of the film winding roller 2 for film cutting.

[0047] As Figure 3 and Figure 4 shown, the label pasting lifting drive device 7 is installed on top of the pressure roller advancing and retreating drive device 5. The label pasting lifting drive device 7 may include a fixed bottom plate 71, a top plate 72, lifting guide columns 73, a lifting drive cylinder 74, a lifting drive seat 75, and a transverse movement guide column 76. The fixed bottom plate 71 is respectively installed on top of the two pressure roller advancing and retreating drive devices 5. The top plate 72 is connected to the fixed bottom plate 71 through the longitudinally arranged lifting guide columns 73. Two lifting drive cylinders 74 are provided and are respectively installed on the corresponding top plates 72. The output rod of the lifting drive cylinder 74 is connected to the lifting drive seat 75 movably installed on the lifting guide columns 73 to drive it to move up and down. Both ends of the transverse movement guide column 76 are connected to the two lifting drive seats 75.

[0048] As Figure 4 shown, a limit buffer 110 for cooperating with the lifting drive seat 75 may also be provided on the fixed bottom plate 71, which can prevent collisions.

[0049] As Figure 3 and Figure 6 shown, the label pasting position transverse movement device 8 is installed on the label pasting lifting drive device 7. The label pasting position transverse movement device 8 may include a label pasting position transverse movement lead screw 81 and an adjusting handwheel 82. Both ends of the label pasting position transverse movement lead screw 81 are connected to the two lifting drive seats 75. One end of the label pasting position transverse movement lead screw 81 passes through one of the lifting drive seats 75 and is connected to the adjusting handwheel 82. When the adjusting handwheel 82 rotates, it can drive the label pasting position transverse movement lead screw 81 to rotate. The label pasting machine mounting plate 91 of the label pasting device 9 is threadedly connected to the label pasting position transverse movement lead screw 81 through a nut seat 83.

[0050] During operation, the label pasting position transverse movement device 8 is in transmission connection with the label fitting device 9 that is movably installed on the label pasting lifting drive device 7. By simply rotating the adjustment handwheel 82, the label fitting device 9 can be driven to move left and right, which is very convenient to operate.

[0051] As Figure 6 , Figure 7 and Figure 8 shown, the label fitting device 9 may include a labeler mounting plate 91, a label tape reel 92, a tape guiding column 93, a label peeling knife 94, an upper stop 95, a fitting brush 96, a waste tape take-up shaft 97, and a take-up shaft rotation motor 98. The transverse guide column 76 passes through the labeler mounting plate 91. The label tape reel 92 is connected to the upper side position at one end of the labeler mounting plate 91 through a connecting plate 99. A plurality of tape guiding columns 93 are provided and are respectively arranged on the labeler mounting plate 91 and the connecting plate 99 (that is, arranged from the label tape reel 92 to the label peeling knife 94 and then back to the waste tape take-up shaft 97). The label peeling knife 94, the upper stop 95, and the fitting brush 96 are respectively installed at the other end of the labeler mounting plate 91 and face the film winding drum 2. The upper stop 95 is located above the label peeling knife 94, and the fitting brush 96 is located above the upper stop 95. The lower end of the fitting brush 96 extends to the lower end of the label peeling knife 94. The waste tape take-up shaft 97 is installed at the lower side position at one end of the labeler mounting plate 91. The take-up shaft rotation motor 98 can be connected to the waste tape take-up shaft 97 through transmission components such as a transmission wheel + transmission belt, a gear set, or a chain and drive it to rotate.

[0052] Before film pasting, the label pasting lifting drive device 7 can drive the label fitting device 9 to move downward to a specified position. During film pasting, driven by the take-up shaft rotation motor 98, the waste tape take-up shaft 97 rotates, thereby driving the label tape on the label tape reel 92 to be conveyed towards the label peeling knife 94. The label tape is folded back at the cutting edge end of the label peeling knife 94. Under the action of the label peeling knife 94, the label on the label tape is separated from the backing paper of the label tape. At this time, the fitting brush 96 can fit the separated label to the specified position on the dust removal film. Subsequently, the backing paper of the label tape will be wound up by the waste tape take-up shaft 97.

[0053] Since the fitting brush 96 is flexible, it will not scratch the dust removal film and can ensure that the label is successfully pasted onto the dust removal film, reducing the probability of missed label pasting. The upper stop 95 plays a limiting role to prevent the label from shifting or falling.

[0054] As Figure 6 and Figure 7As shown, the label attaching device 9 is further provided with a speed adjusting piece 910, an adjusting piece mounting shaft 911 and an adjusting piece locking screw 912 for finely adjusting the conveying speed of the label tape. The adjusting piece mounting shaft 911 is mounted on the labeling machine mounting plate 91 and is located below one of the tape guiding columns 93. The annular tail end of the speed adjusting piece 910 is movably mounted on the adjusting piece mounting shaft 911. The adjusting piece locking screw 912 passes through the annular tail end of the speed adjusting piece 910 and is locked with the adjusting piece mounting shaft 911, thereby fixing the speed adjusting piece 910.

[0055] The upper end of the speed adjusting piece 910 can abut against the lower end part of the tape guiding column 93 located above it, so as to achieve frictional contact with the label tape, and the conveying speed of the label tape is finely adjusted by pressure. Loosen the adjusting piece locking screw 912, and the position of the speed adjusting piece 910 can be adjusted, so as to adjust the pressure tightness between the speed adjusting piece 910 and the label tape, facilitating the adaptation of the labeling speed to the rotational speed of the film winding roller 2.

[0056] As Figure 9 shown, the drum braking device 19 is mounted on one side of the frame 1. The drum braking device 19 may include a brake driving cylinder 191, a brake cylinder mounting bracket 192, a brake pad mounting plate 193, a brake pad hinge seat 194 and a brake pad 195 for frictional contact with the side surface of the film winding roller 2 to stop the rotation of the film winding roller 2. The brake pad 195 may be set as a plastic brake pad. The brake driving cylinder 191 is mounted on one side of the frame 1 through the brake cylinder mounting bracket 192. The brake pad mounting plate 193 is mounted on one side of the frame 1 through the brake pad hinge seat 194. The lower end of the brake pad mounting plate 193 is hinged to the brake pad hinge seat 194. The output rod of the brake driving cylinder 191 is connected to the back surface of the brake pad mounting plate 193. The brake pad 195 is mounted on the front surface of the brake pad mounting plate 193.

[0057] When it is necessary to stop the film winding roller 2, the brake driving cylinder 191 can drive the brake pad 195 to make frictional contact with the side surface of the film winding roller 2. The plastic brake pad will not damage the film winding roller 2.

[0058] As Figure 2 and Figure 4 shown, the photoelectric sensor 13 is mounted on one side of the frame 1. In order to cooperate with the photoelectric sensor 13 for detection, a target position detection object 131 is provided on one side of the film winding roller 2. Each time the photoelectric sensor 13 detects the target position detection object 131, the label attaching device 9 starts to attach a label.

[0059] As Figure 10As shown in the figure, a turntable 22 is provided at one end of the roller rotating shaft 21. An elastic frame 23 is provided on a bracket 14 on one side of the frame 1. An encoder 24 for measuring the number of rotation cycles of the film winding roller 2 is provided at the free end of the elastic frame 23. A counting wheel 25 that rolls on the outer side wall of the turntable is provided on the shaft body of the encoder 24. Preferably, the elastic frame 23 may include a fixed plate 231, a movable plate 232, a swing shaft 233, and a tension spring 234. One end of the fixed plate 231 is fixedly connected to the bracket 14. One end of the movable plate 232 is rotatably connected to the other end of the fixed plate 231 through the swing shaft 233. The movable plate 232 and the fixed plate 231 form an inverted V-shaped structure. The tension spring 234 is connected between the movable plate 232 and the fixed plate 231. The encoder 24 is installed at the other end of the movable plate 232.

[0060] When the film winding roller 2 rotates, it will also drive the turntable 22 and the counting wheel 25 to rotate. In this way, the encoder 24 can obtain the number of rotation cycles of the film winding roller 2, so that the number of turns of the wound film can be obtained.

[0061] After adopting the above dust removal film production equipment, the production method of the dust removal film may include the following steps:

[0062] (1) Pull the first protective film on the first protective film roll 11 between the film sticking pressure roller 4 and the film winding roller 2. Start the rotation of the film winding roller 2. Through the film sticking pressure roller 4, stick and wind the first protective film onto the surface of the film winding roller 2. When the winding of the first protective film is completed (such as winding one turn), stop the rotation of the film winding roller 2. The operator cuts off the tail end of the first protective film with a cutter.

[0063] (2) Pull the dust removal film on the dust removal film roll 10 between the film sticking pressure roller 4 and the film winding roller 2. The label sticking lifting drive device 7 drives the label sticking device 9 to move to a specified height. Start the rotation of the film winding roller 2 again. Through the film sticking pressure roller 4, stick the dust removal film onto the first protective film located on the surface of the film winding roller 2. While the film winding roller 2 is rotating, the label sticking device 9 pastes labels one by one at specified positions on the dust removal film. When the dust removal film has wound a preset number of turns, stop the rotation of the film winding roller 2. The operator cuts off the tail end of the dust removal film with a cutter.

[0064] (3) Pull the second protective film on the second protective film roll 12 between the film sticking pressure roller 4 and the film winding roller 2. Start the rotation of the film winding roller 2 again. Through the film sticking pressure roller 4, stick the second protective film onto the dust removal film. When the winding of the second protective film is completed (such as winding one turn), stop the rotation of the film winding roller 2. The operator cuts off the tail end of the second protective film with a cutter.

[0065] (4) The operator cuts off the dust removal film composite body that has been superposed and wound on the film winding roller 2 along the axial direction of the film winding roller 2 with a cutter, and the finished dust removal film can be obtained by taking it off.

[0066] Among them, every time the winding film roller 2 rotates one circle, the label attaching device 9 attaches one label to the dust removal film. When the finished dust removal film obtained by cutting is unfolded and laid flat, the labels on each layer of the dust removal film are arranged in an overlapping manner from bottom to top, and each label can prevent the label attaching areas of two adjacent layers of the dust removal film from sticking together, which facilitates the user to uncover two adjacent layers of the dust removal film and is convenient for subsequent use.

[0067] After step (3), when it is necessary to cut the dust removal film composite into two parts, the middle film cutting knife 64 of the film cutting device 6 can be started.

[0068] To sum up, the structural design of the present invention is reasonable. It can laminate and rewind two protective films and multiple dust removal films together. And driven by the label attaching lifting drive device and the label attaching position transverse movement device, the label attaching device can move to a specified position to automatically attach labels on the dust removal film. The label attaching accuracy is high, and problems such as missing label attachment, incorrect label attaching position, and poor label attaching effect can be prevented, greatly improving the work efficiency and reducing the labor intensity. In addition, driven by the label attaching lifting drive device and the label attaching position transverse movement device, the label attaching position of the label attaching device of the present invention is adjustable, which can adapt to the label attaching operations of dust removal films of different sizes and the label attaching operations at different positions, with flexible adjustment and good versatility.

[0069] The above embodiments are the preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention shall be equivalent replacement methods and are all included in the protection scope of the present invention.
