Description

A coating unwinding film surface contact dust removal device to reduce the residue of highly adherent particles. Technical Field

[0001] This utility model relates to the field of dust removal devices, and in particular to a coating unwinding film surface contact dust removal device that reduces the residue of highly adherent particles. Background Technology

[0002] Membrane materials are widely used in modern industrial production, including in electronics, optics, and packaging. The coating and unwinding process is a crucial step in membrane material production. However, during this process, various particulate impurities inevitably adhere to the membrane surface, severely impacting its quality and performance. Therefore, a dust removal device is needed to remove residual particles from the membrane surface during coating and unwinding.

[0003] In existing technologies, common methods for removing dust from film surfaces include non-contact dust removal and contact dust removal. Non-contact dust removal methods include using high-pressure air blowing and ion guns to remove particle residues adhering to the film surface. When using contact dust removal, static electricity is usually removed from the film material using antistatic equipment such as static eliminator ion bars, making the film material less prone to attracting dust and facilitating smoother dust removal of particle residues. After the film material passes through the dust removal roller, the roller, which has suitable adsorption force, absorbs the dust and impurities originally adhering to the film surface. The dust removal roller, after absorbing the dust, then contacts the adhesive paper roll. The adhesive paper roll, being sticky, transfers and collects the dust from the surface of the dust removal roller, keeping the roller clean and allowing it to continue its dust removal function. This cycle can effectively remove dust from the film surface during coating unwinding, thereby reducing the residue of highly adhered particles.

[0004] However, during use, the adhesive paper roll continuously absorbs dust and impurities transferred from the dust removal roller, and its surface stickiness will gradually decrease. When the stickiness is low enough, it is difficult to effectively absorb dust and cannot guarantee the cleaning effect on the dust removal roller and other components, thus affecting the dust removal performance of the entire membrane contact dust removal device. Therefore, it needs to be replaced in time to maintain good dust removal efficiency.

[0005] However, the existing adhesive paper rolls are installed in the equipment at both ends by fixed wheels. When changing the paper roll, the fixed wheels need to be removed to change the adhesive paper roll. This makes the replacement of adhesive paper rolls time-consuming, labor-intensive, and inefficient, and cannot meet production requirements. Summary of the Invention

[0006] The main objective of this invention is to provide a coating unwinding film surface contact dust removal device that reduces the residue of highly adherent particles, which can effectively solve the problems in the background art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A coating unwinding film surface contact dust removal device for reducing high-adhesion particle residue includes a support frame. The support frame contains a contact dust removal mechanism, which includes a dust removal roller, concave side plates, a top plate, a bidirectional screw, a T-shaped plate, fixed wheels, and a dust-adhesive paper roll. Two sets of symmetrically arranged dust removal rollers are movably connected inside the support frame. Concave side plates are fixedly connected to the side walls of the support frame. The top plate is fixedly connected to the top surface of the concave side plates. The bidirectional screw is movably connected between the top plates via rotating rods at both ends. The T-shaped plate is movably connected to the bidirectional screw via nuts on its vertical side wall and is also movably connected to the concave side plates via guide rods on its horizontal side wall. The fixed wheels are movably connected to the inner side wall of the horizontal portion of the T-shaped plate via rotating shafts on the side walls. The dust-adhesive paper roll is fixedly connected between the fixed wheels.

[0009] In a preferred embodiment of this utility model, a set of symmetrical horizontal openings are respectively provided on the left and right side walls of the support frame, and vertical openings are respectively provided on the left and right side walls of the support frame above and below the horizontal openings. Two sets of symmetrical first bearing seats with bearings are respectively fixedly installed on the left and right side walls of the support frame between the symmetrical horizontal openings. Roller shafts are fixedly installed at both ends of the dust removal roller and are inserted and fixedly installed together with the bearings in the first bearing seats.

[0010] In a preferred embodiment of this utility model, concave side plates are fixedly installed on the left and right side walls of the support frame at the horizontal position of the transverse opening, and a set of symmetrical first mounting holes are opened on the side wall of the concave side plate. A linear bearing is fixedly installed in the hole of the first mounting hole. The top plate is fixedly installed on the top surface of the concave side plate, and a second bearing seat with a bearing is fixedly installed on the inner side wall of the top plate. A through hole is also opened on the side wall of the top plate.

[0011] In a preferred embodiment of this utility model, the left and right ends of the bidirectional lead screw pass through the vertical opening respectively, and rotating rods are fixedly installed on the left and right end walls of the bidirectional lead screw respectively. The rotating rods are inserted and fixedly installed together with the bearings in the second bearing seat and pass through the through hole, and a handwheel is also fixedly installed on the outer end of one of the rotating rods.

[0012] In a preferred embodiment of this utility model, the T-shaped plate is in an inverted state and has a symmetrical set. A second mounting hole is provided on the vertical side wall of the T-shaped plate. A nut is fixedly installed in the second mounting hole and is threaded together with a two-way lead screw. A set of symmetrical guide rods is fixedly installed on the outer side wall of the transverse part of the T-shaped plate and is inserted into a linear bearing. A third bearing seat with a bearing is fixedly installed on the inner side wall of the transverse part of the T-shaped plate. A rotating shaft is fixedly installed on the outer side wall of the fixed wheel and is inserted into and fixedly installed together with the bearing in the third bearing seat.

[0013] In a preferred embodiment of this utility model, the fixing wheel is conical in shape and is inserted into both ends of the adhesive paper roll.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In this invention, the contact dust removal mechanism allows for easy replacement of the adhesive paper roll. By turning the handwheel, the rotating rod drives the bidirectional lead screw to rotate, causing the symmetrical T-shaped plates to move in opposite directions along the bidirectional lead screw and linear bearing via nuts and guide rods. At this point, the fixed wheel no longer clamps the adhesive paper roll, allowing for easy removal of the old roll. The new roll is then placed between the symmetrical dust removal rollers. Turning the handwheel in the opposite direction causes the fixed wheel to move relative to the T-shaped plate, inserting it into both ends of the roll for positioning and fixation. This replacement method eliminates the need to disassemble the fixed wheel, significantly saving replacement time and improving efficiency. It overcomes the problems of time-consuming, labor-intensive, and inefficient adhesive paper roll replacement in existing technologies, meeting the demands of high-efficiency production, reducing downtime caused by adhesive paper roll replacement, and improving overall production efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] As shown in Figures 1-5, a coating unwinding contact dust removal device for reducing the residue of highly adherent particles includes a support frame 1. The support frame 1 houses a contact dust removal mechanism 2, which includes a dust removal roller 5, concave side plates 8, a top plate 11, a bidirectional lead screw 14, a T-shaped plate 17, fixed wheels 22, and a dust-adhesive paper roll 24. Two sets of symmetrically arranged dust removal rollers 5 are movably connected inside the support frame 1, and concave side plates are fixedly connected to the side walls of the support frame 1. 8. The top plate 11 is fixedly connected to the top surface of the concave side plate 8, and the double-acting screw 14 is movably connected between the top plate 11 through the rotating rods 15 at both ends. The T-shaped plate 17 is movably connected to the double-acting screw 14 through the nut 19 on the side wall of the vertical part, and the T-shaped plate 17 is also movably connected to the concave side plate 8 through the guide rod 20 on the side wall of the horizontal part. The fixed wheel 22 is movably connected to the inner side wall of the horizontal part of the T-shaped plate 17 through the rotating shaft 23 on the side wall, and the dust-adhesive paper roll 24 is fixedly connected between the fixed wheels 22.

[0024] As shown in Figure 2, a set of symmetrical horizontal openings 3 are respectively opened on the left and right side walls of the support frame 1. The horizontal openings 3 provide a channel for the movement of the fixed wheel 22. Vertical openings 4 are also opened on the left and right side walls of the support frame 1 above and below the horizontal openings 3. The vertical openings 4 can ensure the normal use of the bidirectional lead screw 14. Two sets of symmetrical bearing seats 7 with bearings are fixedly installed on the left and right side walls of the support frame 1 between the symmetrical horizontal openings 3. Roller shafts 6 are fixedly installed at both ends of the dust removal roller 5 and are inserted and fixedly installed together with the bearings in the first bearing seats 7. The roller shafts 6 at both ends of the dust removal roller 5 are inserted and fixedly installed in the bearings in the first bearing seats 7, so that the dust removal roller 5 can rotate freely around the roller shafts 6. When the membrane material passes between the dust removal rollers 5, the rotating dust removal roller 5 contacts the surface of the membrane material and uses its own adsorption force to adsorb the particulate impurities on the surface of the membrane material.

[0025] As shown in Figure 3, concave side plates 8 are fixedly installed on the left and right side walls of the support frame 1 at the horizontal position of the transverse opening 3, and a set of symmetrical first mounting holes 9 are opened on the side wall of the concave side plate 8. A linear bearing 10 is fixedly installed in the hole of the first mounting hole 9. The top plate 11 is fixedly installed on the top surface of the concave side plate 8, and a second bearing seat 12 with a bearing is fixedly installed on the inner side wall of the top plate 11. A through hole 13 is also opened on the side wall of the top plate 11. The linear bearing 10 is installed in the first mounting hole 9 on the side wall of the concave side plate 8 to cooperate with the guide rod 20 on the T-shaped plate 17 and play a guiding role. The top plate 11 is fixed on the top surface of the concave side plate 8. The second bearing seat 12 on the inner side wall is used to install the rotating rods 15 at both ends of the bidirectional lead screw 14, so that the bidirectional lead screw 14 can rotate around the rotating rod 15. The through hole 13 provides space for the rotating rod 15 to pass through and ensures the smooth rotation of the rotating rod 15.

[0026] As shown in Figure 4, the left and right ends of the bidirectional lead screw 14 pass through the vertical opening 4 respectively, and rotating rods 15 are fixedly installed on the left and right end walls of the bidirectional lead screw 14 respectively. The rotating rods 15 are inserted and fixedly installed together with the bearing in the second bearing seat 12 and pass through the through hole 13. A handwheel 16 is also fixedly installed on the outer end of one of the rotating rods 15. When the handwheel 16 is rotated, the handwheel 16 drives the rotating rod 15 to rotate, thereby causing the bidirectional lead screw 14 to rotate. Since the bidirectional lead screw 14 has a bidirectional thread, when it rotates, it will drive the nut 19 connected to it, that is, the T-shaped plate 17 that is symmetrical on the left and right to move relative to or in opposite directions.

[0027] As shown in Figure 4, the T-shaped plate 17 is inverted and has a symmetrical set of guide rods. A second mounting hole 18 is provided on the vertical sidewall of the T-shaped plate 17, and a nut 19 is fixedly installed in the second mounting hole 18. The nut 19 is threadedly connected to the bidirectional lead screw 14. A set of symmetrical guide rods 20 is fixedly installed on the outer sidewall of the transverse part of the T-shaped plate 17, and the guide rods 20 are inserted into the linear bearing 10. A third bearing seat 21 with a bearing is fixedly installed on the inner sidewall of the transverse part of the T-shaped plate 17, and a fixed wheel 22 is fixedly installed on its outer sidewall. A rotating shaft 23 is fixedly installed and inserted into the bearing inside the third bearing seat 21. A nut 19 is threadedly connected to a double-acting screw 14, allowing the T-shaped plate 17 to move under the rotation of the double-acting screw 14. A guide rod 20 on the outer side wall of the transverse part is inserted into a linear bearing 10, which serves to guide and stabilize the movement of the T-shaped plate 17. The third bearing seat 21 on the inner side wall of the transverse part is used to install the rotating shaft 23 on the outer side wall of the fixed wheel 22, so that the fixed wheel 22 can rotate around the rotating shaft 23. The fixed wheel 22 is used to fix or release the sticky paper roll 24.

[0028] As shown in Figure 4, the fixing wheel 22 is conical in shape and is inserted into both ends of the adhesive paper roll 24. Utilizing the characteristics of the conical structure, when the fixing wheel 22 is inserted into both ends of the adhesive paper roll 24, it will exert a certain squeezing force on the adhesive paper roll 24, thereby firmly fixing the adhesive paper roll 24 between the fixing wheels 22. The conical fixing wheel 22 can effectively fix the adhesive paper roll 24, preventing it from loosening or shifting during rotation and movement, ensuring the stability and reliability of the contact between the adhesive paper roll 24 and the dust removal roller 5. When the adhesive paper roll 24 contacts the dust removal roller 5, it uses its own adhesiveness to adsorb the dust on the dust removal roller 5. This ensures that the adhesive paper roll 24 continuously and effectively collects the dust on the dust removal roller 5, maintaining the good dust removal performance of the device and improving the quality and effect of membrane surface contact dust removal.

[0029] The specific operating principle of the contact dust removal mechanism 2 is as follows:

[0030] As shown in Figure 5, when the film material passes between the two sets of symmetrical dust removal rollers 5, it will drive the dust removal rollers 5 to rotate. The roller shafts 6 at both ends of the dust removal rollers 5 will rotate through the first bearing seat 7 with bearings. After the dust removal rollers 5 come into contact with the film surface, they will use their own adsorption force to adsorb particulate impurities on the film surface. During the rotation of the dust removal rollers 5, the sticky paper roll 24 will rotate. The sticky paper roll 24 will drive the rotating shafts 23 at both ends to rotate. The rotating shafts 23 will use the third bearing seat 21 with bearings to rotate the sticky paper roll 24. During the rotation, the sticky paper roll 24 will use its own adhesiveness to adsorb the dust on the dust removal rollers 5. This can ensure that the sticky paper roll 24 continuously and effectively collects the dust on the dust removal rollers 5, so as to achieve effective contact dust removal on the film surface for coating unwinding.

[0031] When the adhesive paper roll 24 needs to be replaced due to reduced stickiness after prolonged use, manually turn the handwheel 16 after stopping the machine. The handwheel 16 will drive the rotating rod 15, which passes through the through holes 13 on the side wall of the top plate 11, to rotate within the second bearing seat 12 with bearings installed on the inner side wall of the top plate 11. The rotating rod 15 will drive the bidirectional lead screw 14 to rotate. During the rotation of the bidirectional lead screw 14, because the left and right symmetrical T-shaped plates 17 are respectively installed through the nuts 19 in the second mounting holes 18 opened in the vertical side wall, they are connected to the bidirectional lead screw 14. The four threads are connected together, so the symmetrical T-shaped plates 17 will move in opposite directions. During the movement, the guide rod 20 installed on the outer wall of the T-shaped plate 17 will move along the linear bearing 10 installed in the first mounting hole 9 on the side wall of the concave side plate 8 to guide the movement of the T-shaped plate 17. As the T-shaped plate 17 moves, it will drive the fixed wheel 22 movably installed on the inner side wall to move in opposite directions from both ends of the adhesive paper roll 24 until the fixed wheel 22 no longer clamps and fixes the adhesive paper roll 24, at which point the old adhesive paper roll 24 can be removed. To replace the old adhesive paper roll 24, remove it and place the new roll between the symmetrical dust removal rollers 5. Ensure the new roll is in close contact with the rollers. Then, reverse the handwheel 16, which in turn rotates the rotating rod 15 to reverse the bidirectional lead screw 14, causing the symmetrical T-plates 17 to move relative to each other until the fixing wheels 22 mounted on the opposite sides of the T-plates 17 are inserted into both ends of the adhesive paper roll 24. The fixing wheels 22, utilizing their conical structure, will generate a certain squeezing force at both ends of the adhesive paper roll 24 to press the roll 24 firmly against the dust. 4. Securely fix the paper roll 24 between the fixed wheels 22 until the handwheel 16 can no longer be rotated. This facilitates the quick replacement of the adhesive paper roll 24 in the existing contact dust removal device used for coating and unwinding film. This replacement method eliminates the need to disassemble the fixed wheels 22, greatly saving replacement time and improving replacement efficiency. It overcomes the problems of time-consuming, labor-intensive, and inefficient replacement of adhesive paper rolls in the prior art, meets the high-efficiency production requirements, reduces the problem of long downtime caused by replacing adhesive paper roll 24, and improves production efficiency.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
