Description

Technical Field

[0001] This invention relates to the field of aluminum alloy door and window technology, specifically to an aluminum alloy profile film applicator that is easy to adjust and use. Background Technology

[0002] Aluminum alloy profiles are alloys made of aluminum and various metallic elements. Aluminum alloy doors and windows have many advantages, are not prone to corrosion, and have a service life that is much longer than doors and windows made of other materials. When manufacturing aluminum alloy profiles, the length is relatively long, about 6 meters. In order to avoid scratches on the profiles during manufacturing, a protective film needs to be manually applied to the outside of the profiles.

[0003] In existing technologies, film application is usually done manually. However, due to the excessive length of the profile, it is difficult to ensure that the film is applied correctly during manual application, resulting in the protective film not being able to cover the entire surface of the profile and causing a waste of labor and materials for secondary film application.

[0004] Secondly, when applying protective film to the surface of aluminum alloy profiles with grooves, the grooves on the surface of the aluminum alloy profile will cause the protective film to wrinkle as it is pressed and applied at the front end. Continuing to press and apply the film will significantly increase the wrinkles when applying the protective film later.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing aluminum alloy profile film applicator. Summary of the Invention

[0006] The present invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different solution. Specifically, the present invention aims to provide an easy-to-adjust and usable aluminum alloy profile film applicator to solve the problems mentioned in the background art, such as the tendency for manual film application to result in misalignment and the tendency for wrinkles to form when applying film to aluminum alloy profiles with grooved surfaces.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an aluminum alloy profile film applicator that is easy to adjust and use, comprising a support frame for mounting on two parallel aluminum alloy profiles, wherein the support frame moves by translating along the length of the aluminum alloy profile; the support frame is provided with an adjustment mechanism to adapt to aluminum alloy profiles of different widths while the support frame is installed. The installation mechanism is located at the top of the support frame to ensure that both sides of the protective film are located at the edge of the aluminum alloy profile when using protective films of different widths. An anti-wrinkle mechanism is located inside the support frame. The anti-wrinkle mechanism includes two symmetrically arranged rollers. Each roller has two symmetrically arranged spiral components on its outer wall. The spiral components move with the rollers as they rotate. The protective film is flattened by moving from the center to both sides through the contact point between the spiral components and the protective film. The anti-wrinkle mechanism is equipped with a drive assembly for driving the rollers to rotate. A clamping mechanism is located at one end of the support frame in the direction of movement. The clamping mechanism includes a flexible pressure strip, which is used to adaptively attach the protective film to the upper surface of the aluminum alloy by deforming itself when the flexible pressure strip is subjected to downward pressure.

[0008] Furthermore, the support frame includes two sets of fixed side plates and a limiting plate located between them. Two sets of adjusting screws are provided between the two sets of fixed side plates. Both ends of the two sets of adjusting screws pass through the two sets of fixed side plates. Both ends of the two sets of adjusting screws are provided with positioning nuts that are threadedly engaged with them. A connecting plate is fixed to the top of the limiting plate. The top of the connecting plate is provided with an upward-facing groove.

[0009] Furthermore, the adjustment mechanism includes through slots respectively opened at the lower ends of the two sets of fixed side plates and extending to one side, with two sets of positioning plates separated inside the through slots of the two sets of fixed side plates. The two sets of positioning plates are respectively fixed to the two end faces of the connecting plate.

[0010] Furthermore, one outer wall of each of the two sets of fixed side plates is fixed with a fixed insert plate on the top of a set of positioning plates. The fixed insert plate is provided with a first positioning bolt that is threadedly engaged with it. The top of the set of positioning plates is provided with positioning holes that are threadedly engaged with the first positioning bolt at equal intervals.

[0011] Furthermore, each of the through slots is fitted with an L-shaped fixing plug, and each of the two sets of fixing side plates is fixed with a fixing screw that passes through the L-shaped fixing plug. The outer wall of each fixing screw is provided with a fixing nut that is threaded to it. Each of the L-shaped fixing plugs is fixed with a plug rod on the outer wall facing the other set of positioning plates. The outer wall of the other set of positioning plates is provided with slots at equal intervals that fit with the plug rod.

[0012] Furthermore, the installation mechanism includes support rods respectively fixed to the top of two sets of fixed side plates. The support rods have a first U-shaped groove through which a matching shaft is provided. A partition plate is fixed in the middle of the shaft, and a protective film fixing plate is provided on both sides of the outer wall of the shaft located on the partition plate.

[0013] Furthermore, the installation mechanism also includes a limiting ring sleeved on the outer wall of the partition plate. A bottom rod is longitudinally fixed at the bottom of the limiting ring. The lower end of the bottom rod is provided with an insert cylinder fixed in the middle of the groove of the connecting plate and matching the bottom rod. The partition plate and the limiting ring are rotatably connected by ball bearings.

[0014] Furthermore, the clamping mechanism includes a second U-shaped slot respectively corresponding to the sidewalls of the two sets of fixed side plates. A square tube is fixed on the upper surface of the second U-shaped slot. A serrated steel sheet is provided on one outer wall of the square tube. A T-shaped connecting strip penetrating the bottom is provided on the inner side of the square tube. A flexible pressure strip is fixed at the bottom of the T-shaped connecting strip. A first spring is fixed at equal intervals between the inner wall of the square tube and the T-shaped connecting strip.

[0015] Furthermore, the anti-wrinkle mechanism also includes a small air pump fixed to one end of the groove of the connecting plate. The air pump is connected to a T-shaped connecting pipe at its suction end. The bottom of the groove of the connecting plate is symmetrically fixed with two inner plates located on both sides of the T-shaped connecting pipe. The inner plates are rotatably connected to a first connecting shaft. One end of the roller is respectively provided with a sleeve fitted on the outer wall of one end of the first connecting shaft. The outer wall of the sleeve is symmetrically provided with a second positioning bolt threaded to it. The two ends of the T-shaped connecting pipe are respectively inserted into the two sets of sleeves.

[0016] Furthermore, the spiral component is a spiral outer tube, and the outer wall of the spiral outer tube is provided with locking pins that slide and seal with it at equal intervals. One end of the locking pin located on the outside of the spiral outer tube is set with a cross-shaped structure, and the other end of the locking pin is fixed with a connecting block. A second spring sleeved on the outside of the locking pin is fixed between the connecting block and the spiral outer tube. And / or, the drive assembly includes guide wheels mounted on both sides of the connecting plate, and a second connecting shaft symmetrically arranged in the groove of the connecting plate and rotatably connected to the connecting plate. One end of the second connecting shaft passes through the outer side of the connecting plate and is connected to the guide wheel. A transmission belt is sleeved on the outer wall of the first connecting shaft and the second connecting shaft. Elastic telescopic rods are fixed on both sides of the bottom of the groove of the connecting plate located on the fixed inner plate. A movable seat is fixed at the telescopic end of the elastic telescopic rod. A pressure roller passing through the connecting plate is fixed on the outer wall of the movable seat. A movable groove located on the outer side of the pressure roller is correspondingly opened on the outer wall of the connecting plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are: In this invention, under the action of the adjustment mechanism, two sets of movable fixed side plates move closer to each other. The position of the fixed side plates is adjusted according to the size of the aluminum alloy profile. Under the action of the installation mechanism, the protective film roll adapted to the aluminum alloy profile is sleeved on the outer wall of the protective film fixing plate. Pulling one end of the protective film on the protective film roll requires a certain pulling force due to the adhesive surface of the protective film having a certain degree of stickiness. One end of the protective film is passed through the bottom surface of one set of pressure rollers, the top surface of the spiral outer tube, and the bottom surface of another set of pressure rollers in sequence. Under the action of the first spring, the flexible pressure strip will press one end of the protective film tightly against the upper surface of the aluminum alloy profile. If the surface of the aluminum alloy profile has grooves or is not completely flat, the bottom surface of the flexible pressure strip will adaptively deform and conform to the surface of the aluminum alloy profile, thereby ensuring the complete adhesion of the protective film. In this film application method, films can be applied to aluminum alloy profiles of different specifications, and the phenomenon of skewing during film application can be prevented.

[0018] In this invention, during the application of the protective film, the guide wheel located below the protective film rolls along the upper surface of the aluminum alloy profile, causing the second connecting shaft to rotate clockwise. Under the action of the transmission belt, the roller rotates, causing the spiral outer tube on the outer wall to rotate clockwise synchronously. Since the two sets of spiral outer tubes on the roller spiral counterclockwise from the center to both sides on the bottom surface of the protective film, the clockwise rotation of the spiral outer tubes causes the contact point between the protective film and the top of the spiral outer tubes to continuously change, creating a tendency to move from the center to both sides. This movement trend produces the effect of unfolding the protective film from the center to both sides, thus protecting the film. With the film fully unfolded, the rollers and spiral outer tube act as drive rollers to transfer the protective film. Simultaneously, a small air pump is turned on. As the spiral outer tube rotates, the top pin is squeezed by the protective film. After the pin slides, the gap between the inside of the spiral outer tube and the cross-shaped structure of the pin connects. This allows air to be drawn into the bottom of the protective film through the slots on the spiral outer tube located on the outside of the pin. The change in the contact point between the spiral outer tube and the protective film, combined with the unfolding effect of the spiral outer tube during rotation, further improves the unfolding and flattening effect of the protective film during application, preventing wrinkles.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1 to 13 This invention provides a technical solution: an aluminum alloy profile film applicator that is easy to adjust and use, comprising: The support frame is used to be installed on two parallel aluminum alloy profiles by moving them in opposite directions before the film is applied, and it can be moved horizontally along the length of the aluminum alloy profiles; the support frame is equipped with an adjustment mechanism to adapt to aluminum alloy profiles of different widths while the support frame is installed. The installation mechanism is located at the top of the support frame and is used to ensure that the edges of the protective film are aligned with the edges of the aluminum alloy profile for covering and attaching when using protective films of different widths. The anti-wrinkle mechanism is located inside the support frame. The anti-wrinkle mechanism includes two symmetrically arranged rollers 29. Each roller 29 has two symmetrically arranged spiral parts on its outer wall. When the two spiral parts rotate, they move from the middle to both sides of the protective film through the contact point with the protective film. The anti-wrinkle mechanism is provided with a drive assembly for driving the rollers 29 to rotate. The clamping mechanism is located at one end of the moving direction of the support frame. The clamping mechanism includes a flexible pressure strip 24, which is used to adaptively attach the protective film to the upper surface of the aluminum alloy by deforming itself when the flexible pressure strip 24 is subjected to downward pressure.

[0023] The support frame includes two sets of fixed side plates 1 and a limiting plate 13 located between them. Two sets of adjusting screws 2 are provided between the two sets of fixed side plates 1. Both ends of the two sets of adjusting screws 2 pass through the two sets of fixed side plates 1. Both ends of the two sets of adjusting screws 2 are provided with positioning nuts 3 that are threadedly engaged with them. A connecting plate 8 is fixed to the top of the limiting plate 13. The top of the connecting plate 8 is provided with an upward-facing groove.

[0024] In practice, the two sets of adjusting screws 2 and the matching positioning nuts 3 can not only limit the fixed side plate 1, but also support the overall frame of the film applicator. The connecting plate 8 and the limiting plate 13 have the same width, so as to prevent the protective film from being blocked by the connecting plate 8 when applying the film.

[0025] The adjustment mechanism includes through slots that are respectively opened at the lower end of the two sets of fixed side plates 1 and extend to one side. Two sets of positioning plates 4 are arranged inside the through slots of the two sets of fixed side plates 1. The two sets of positioning plates 4 are fixed to the two end faces of the connecting plate 8 respectively.

[0026] In practice, the bottom surface of one set of positioning plates 4 should be higher than the bottom surface of the connecting plate 8 and lower than the bottom surface of the pressure roller 41, and the bottom surface of the other set of positioning plates 4 should be in the same plane as the bottom surface of the connecting plate 8.

[0027] Two sets of fixed side plates 1 have fixed insert plates 5 fixed on one side of the outer wall of a set of positioning plates 4 respectively. The fixed insert plates 5 are provided with first positioning bolts 6 that are threadedly engaged with them. The top of the set of positioning plates 4 is provided with positioning holes 7 that are threadedly engaged with the first positioning bolts 6 at equal intervals.

[0028] L-shaped fixing plugs 9 are fitted at the opening of the through groove. Fixing screws 10 that pass through the L-shaped fixing plugs 9 are fixed to the side walls of the two sets of fixing side plates 1 respectively. Fixing nuts 11 that are threadedly engaged with the outer walls of the fixing screws 10 are provided. Insert rods 12 are fixed to the outer walls of the L-shaped fixing plugs 9 facing the other set of positioning plates 4. Slots that fit with the insert rods 12 are provided at equal intervals on the outer walls of the other set of positioning plates 4.

[0029] The installation mechanism includes support rods 14 fixed to the top of two sets of fixed side plates 1 respectively. The support rods 14 have a first U-shaped groove through which a matching shaft 15 is provided. A partition plate 16 is fixed in the middle of the shaft 15. Protective film fixing plates 17 are provided on both sides of the outer wall of the shaft 15 located on the partition plate 16.

[0030] In practice, the protective film roll is an existing technology, and the inner fixing tube can be made of paper, which makes it easy for the protective film roll to be fixed on the protective film fixing plate 17.

[0031] The installation mechanism also includes a limiting ring 18 sleeved on the outer wall of the partition plate 16. A bottom rod 19 is longitudinally fixed at the bottom of the limiting ring 18. The lower end of the bottom rod 19 is provided with an insert 20 fixed in the middle of the groove of the connecting plate 8 and matched with the bottom rod 19. The partition plate 16 and the limiting ring 18 are rotatably connected by ball bearings.

[0032] In practice, the separator 16 and the limiting ring 18 adopt a ball bearing structure with equal angle distribution, which allows the separator 16 to rotate within the limiting ring 18. The bottom rod 19 at the bottom of the limiting ring 18 is inserted into the insert cylinder 20 to limit the separator 16, thus preventing the film roll from shifting during film application.

[0033] The clamping mechanism includes a second U-shaped slot that is respectively opened on the side wall of the two sets of fixed side plates 1. A square tube 21 is fixed on the upper surface of the second U-shaped slot. A serrated steel sheet 22 is provided on one outer wall of the square tube 21. A T-shaped connecting strip 23 that penetrates the bottom is provided on the inner side of the square tube 21. A flexible pressure strip 24 is fixed at the bottom of the T-shaped connecting strip 23. A first spring 2401 is fixed at equal intervals between the inner wall of the square tube 21 and the T-shaped connecting strip 23.

[0034] In practice, the first spring 2401 provides downward pressure to the flexible pressure strip 24, and the bottom surface of the flexible pressure strip 24 will adaptively deform and fit the surface of the aluminum alloy profile.

[0035] The anti-wrinkle mechanism also includes a small air pump 25 fixed to one end of the groove of the connecting plate 8. The air pump 25 is connected to a T-shaped connecting pipe 26. The bottom of the groove of the connecting plate 8 is symmetrically fixed with two fixed inner plates 27 located on both sides of the T-shaped connecting pipe 26. The interior of each fixed inner plate 27 is rotatably connected with a first connecting shaft 28. One end of the roller 29 is respectively provided with a sleeve 30 sleeved on the outer wall of one end of the first connecting shaft 28. The outer wall of the sleeve 30 is symmetrically provided with a second positioning bolt 31 threaded to it. The two ends of the T-shaped connecting pipe 26 are respectively inserted into the interior of the two sets of sleeves 30.

[0036] In practice, the small air pump 25 is a conventional existing technology and can be a wireless charging device. The outer walls of both ends of the T-shaped connecting pipe 26 are provided with sealing rings between them and the first connecting shaft 28 to ensure the internal air suction effect of the roller 29.

[0037] The spiral component is a spiral outer tube 32. The outer wall of the spiral outer tube 32 is provided with equally spaced locking posts 33 that slide and seal with it. One end of the locking post 33 located outside the spiral outer tube 32 is set with a cross-shaped structure. The other end of the locking post 33 is fixed with a connecting block 34. A second spring 35 sleeved on the outside of the locking post 33 is fixed between the connecting block 34 and the spiral outer tube 32. And / or, the drive assembly includes guide wheels 37 mounted on both sides of the connecting plate 8, and a second connecting shaft 36 symmetrically arranged in the groove of the connecting plate 8 and rotatably connected to the connecting plate 8. One end of the second connecting shaft 36 passes through the outer side of the connecting plate 8 and is connected to the guide wheel 37. A transmission belt 38 is sleeved on the outer wall of the first connecting shaft 28 and the second connecting shaft 36. Elastic telescopic rods 39 are fixed on both sides of the bottom of the groove of the connecting plate 8 located on the fixed inner plate 27. A movable seat 40 is fixed at the telescopic end of the elastic telescopic rod 39. A pressure roller 41 passing through the connecting plate 8 is fixed on the outer wall of the movable seat 40. A movable groove located on the outer side of the pressure roller 41 is correspondingly opened on the outer wall of the connecting plate 8.

[0038] In practice, the suction pressure generated by the small suction pump 25 is less than the elastic force of the second spring 35, and the bottom surface of the guide wheel 37 and the bottom surface of the connecting plate 8 are on the same plane.

[0039] Working principle: First, place the film applicator on two pre-positioned horizontal aluminum alloy profiles. The outer walls of one side of the two aluminum alloy profiles are respectively attached to the outer walls of the limiting plate 13, and the bottom surface of the positioning plate 4 on one side of the L-shaped fixing plug 9 is attached to the top surface of the two aluminum alloy profiles. Rotate the positioning nut 3, the first positioning bolt 6 and the fixing nut 11 to move the first positioning bolt 6 out of the positioning hole 7 at the top of the first set of positioning plates 4, and remove the L-shaped fixing plug 9 so that the insertion rod 12 on its outer wall is moved out of the slot on the side wall of the other set of positioning plates 4. At this time, the two sets of fixing side plates 1 can be moved closer to each other until the outer walls of the fixing side plates 1 are respectively attached to the outer walls of the aluminum alloy profiles. At this time, the positioning nut 3 is screwed on both ends of the adjusting screw 2 to limit the fixing side plates 1. Then, the first positioning bolt 6 is inserted into the corresponding positioning hole 7 at the top of the first set of positioning plates 4, and the insertion rod 12 on the outer wall of the L-shaped fixing plug 9 is inserted into the corresponding slot on the side wall of the other set of positioning plates 4. The fixing nut 11 is tightened on the outer wall of the fixing screw 10.

[0040] Next, the installation mechanism is removed by moving the insert 20 out through the bottom rod 19. The protective film roll adapted to the aluminum alloy profile is then placed on the outer wall of the protective film fixing plate 17. Since the central paper tube size of the protective film roll is fixed, the outer wall of the protective film fixing plate 17 can slightly squeeze the inner wall of the central paper tube, thereby causing the protective film fixing plate 17 to rotate when the protective film roll is unwound. After the protective film roll is assembled, the installation mechanism can be limited by inserting the insert 20 through the bottom rod 19 and engaging the first U-shaped groove of the support rod 14 through the shaft rod 15.

[0041] At this point, pull one end of the protective film roll. Since the adhesive surface of the protective film has a certain degree of stickiness, a certain pulling force is required when unwinding. Pass one end of the protective film through the bottom surface of a set of pressure rollers 41, the top surface of the spiral outer tube 32, and the bottom surface of another set of pressure rollers 41 in sequence, and lift the flexible pressure strip 24. The flexible pressure strip 24 pushes the T-shaped connecting strip 23 upward and squeezes the first spring 2401. At this time, pull one end of the protective film and attach it to the upper surface of one end of the aluminum alloy profile. Release the flexible pressure strip 24. Under the action of the first spring 2401, the flexible pressure strip 24 will press one end of the protective film tightly and attach it to the upper surface of the aluminum alloy profile. If there are grooves or non-perfectly flat surfaces on the surface of the aluminum alloy profile, the bottom surface of the flexible pressure strip 24 will adapt to the deformation and fit the surface of the aluminum alloy profile, thereby ensuring the complete attachment of the protective film. In addition, under this film application method, aluminum alloy profiles of different specifications can be applied, and the phenomenon of skewing during film application can be prevented.

[0042] Then, by moving the film applicator, the protective film is applied along the upper surface of the aluminum alloy profile. During the application process, the flexible pressure strip 24 is used to press and move the film to complete the application. Since one end of the protective film is pressed by the flexible pressure strip 24, the protective film roll needs to be pulled to rotate during unwinding. Therefore, during the unwinding process, the protective film located on the top surface of the spiral outer tube 32 will generate a certain downward pressure. During the film application process, the guide wheel 37 located below the protective film will roll along the upper surface of the aluminum alloy profile, causing the second connecting shaft 36 to rotate clockwise. Under the action of the transmission belt 38, the first connecting shaft 28 rotates clockwise on the outer wall of the T-shaped connecting tube 26. A connecting shaft 28 drives the roller 29 to rotate synchronously through a fixedly installed sleeve 30. During the rotation of the roller 29, the spiral outer tube 32 on the outer wall will rotate synchronously clockwise. Since the two sets of spiral outer tubes 32 on the roller 29 spiral counterclockwise from the middle to both sides on the bottom surface of the protective film, the clockwise rotation of the spiral outer tube 32 will cause the contact point between the protective film and the top of the spiral outer tube 32 to change continuously, forming a tendency to move from the middle to both sides. This tendency will produce the effect of unfolding the protective film from the middle to both sides. Even if the protective film is fully unfolded, the roller 29 and the spiral outer tube 32 can act as transmission rollers to transfer the protective film.

[0043] While the protective film unfolds from the center to both sides, the small suction pump 25 is turned on, and suction is generated from inside the roller 29 through the T-shaped connecting pipe 26. As the spiral outer tube 32 rotates, the top locking post 33 is squeezed by the protective film, causing it to slide into the spiral outer tube 32. The locking post 33 pushes the connecting block 34, which pulls the second spring 35. The negative pressure suction generated by the small suction pump 25 inside the spiral outer tube 32 is less than the preload of the second spring 35 to prevent the locking post 33 from being sucked in when it is not under pressure. Since the upper end of the locking post 33 has a cross-shaped structure, after the locking post 33 slides, the inside of the spiral outer tube 32 is connected to the gap of the cross-shaped structure of the locking post 33. The spiral outer tube 32 can then generate an air suction effect on the bottom surface of the protective film through the hole groove on the outside of the locking post 33. After the contact point between the spiral outer tube 32 and the protective film changes, the squeezed locking post 33 is reset under the action of the second spring 35. Combined with the unfolding effect of the spiral outer tube 32 when it rotates, the effect of unfolding and flattening the protective film during application is further improved, avoiding wrinkling.

[0044] Finally, the flattened protective film is kept flat by the lower right edge of the positioning plate 4, and then pressed and attached to the surface of the aluminum alloy profile by the flexible pressure strip 24. When the guide wheel 37 rolls out of the upper surface of the aluminum alloy profile, the small air pump 25 is turned off until the protective film covers the upper surface of the aluminum alloy profile. The right side of the film applicator is lifted to tilt it, and the protective film is cut off by the serrated steel strip 22. If the last small section of the protective film is not applied properly, it can be applied manually.

[0045] In the above process, although the aluminum alloy profiles are of different sizes, there are relatively few types of sizes. Therefore, rollers 29 of different lengths can be prefabricated for aluminum alloy profiles of different sizes. When the aluminum alloy profile to be filmed changes, the rollers 29 can be replaced by rotating the second positioning bolt 31. The rollers 29 of the corresponding size can be replaced to complete the film application, thereby ensuring that the spiral outer tube 32 unfolds from the middle of the protective film to both sides when the rollers 29 rotate.

[0046] Although the present invention 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 the present invention should be included within the protection scope of the present invention.
