Description

Technical Field

[0001] The invention relates to the field of door and window coating, and in particular to a thermally-insulated aluminum door and window flip coating device. Background Art

[0002] Door and window laminating machine is a kind of equipment specially used for laminating door and window profiles. The laminating methods are divided into three types: cold glue laminating, hot glue laminating and thermal transfer laminating. Among them, cold glue laminating is to apply glue on the surface of door and window profiles and film, and apply a certain pressure through devices such as pressure rollers to make the film and profile fit closely, and use the viscosity of glue to achieve lamination. The glue naturally solidifies at room temperature or accelerates the curing through a specific curing agent; hot glue laminating uses hot melt adhesive as the adhesive material. The hot melt adhesive is first heated to a molten state, coated on the surface of the profile or film, and then pressed through a pressure roller. In the process of cooling and solidifying the hot melt adhesive, the film and profile are firmly bonded; thermal transfer laminating is to transfer the patterns, colors, etc. on the transfer paper or film to the surface of the door and window profile through high temperature and high pressure, so that the profile surface has various decorative effects.

[0003] However, in the daily use of existing door and window laminating machines, the pressure regulating device cannot flexibly and accurately adjust the pressure of the laminating roller due to problems such as thread wear and jamming. The uneven pressure on the film caused by the pressure regulating device will cause the laminating roller to be unable to fully contact certain parts of the profile and apply sufficient pressure, resulting in loose fit between the film and the profile, bubbles and hollowing, etc., which reduces the overall firmness of the laminating and makes the film easy to fall off in subsequent use. How to solve these problems has become an urgent problem to be solved by technicians in this field. Summary of the invention

[0004] In order to make up for the above shortcomings, the present invention provides a thermally-insulated aluminum door and window flip coating device, which aims to solve the problem that the existing pressure regulating device cannot flexibly and accurately adjust the pressure of the coating roller due to wear and other problems during long-term use.

[0005] The present invention is achieved in that: The present invention provides a flip film coating device for broken bridge aluminum doors and windows, comprising a base, a flip mechanical fixture and a film coating machine, wherein the flip mechanical fixture is installed on the top of the base, the film coating machine is installed on the top of the base, the film coating machine comprises a bracket, a conveying member, a film coating roller and a cutting member, the bracket is fixedly connected to the top of the base, the conveying member is installed on the outer wall of the bracket, the film coating roller is rotatably connected to the top of the bracket, the cutting member is installed on the outer wall of the bracket, and further comprises: A pressing component is located on the outer wall of the bracket and is used to ensure that sufficient pressure is applied to the protective film on the surface of the workpiece.

[0006] A clamping assembly is located on the outer wall of the conveying member, and is used to ensure that the workpiece remains stable during the transportation of the conveying member.

[0007] Preferably, the pressing assembly includes a push rod, a fixing member, a sliding rod, a connecting member, a spring 1 and a pressure roller, the push rod is fixedly connected to the outer wall of the bracket, the fixing member is fixedly connected to the bottom of the push rod, the sliding rod is installed at the bottom of the fixing member, the connecting member is fixedly connected to the bottom end of the sliding rod, the spring 1 is arranged on the outside of the sliding rod, and the pressure roller is rotatably connected to the outer wall of the connecting member.

[0008] Preferably, the top end of the sliding rod penetrates the fixing member and the top rod and extends to the top of the top rod, and the outer wall of the sliding rod is slidably connected to the inner wall through which the fixing member is penetrated and the inner wall through which the top rod is penetrated.

[0009] By adopting the above technical solution, the sliding rod can slide inside the fixing member and inside the push rod.

[0010] Preferably, the top and bottom of the spring 1 are fixedly connected to the bottom of the fixing member and the top of the connecting member respectively, and the outer wall of the pressing roller contacts the top of the workpiece placed on the surface of the conveying member.

[0011] By adopting the above technical solution, the presence of spring 1 applies pressure to the pressing roller through the connecting piece, thereby ensuring that the surface of the pressing roller is always in contact with the top of the workpiece and applying sufficient pressure to the workpiece.

[0012] Preferably, the clamping assembly includes a shell, a connecting rod, a pressure rod, an auxiliary part, an extension rod, a movable plate, a connecting plate, a splint, a rotating rod, a rotating wheel, a bent rod and a frame. The shell is arranged on the outside of the conveying member, the connecting rod is fixedly connected to the outer wall of the connecting member, the pressure rod is fixedly connected to one end of the connecting rod, the auxiliary part is arranged on the inside of the shell, the extension rod is installed on the outer wall of the shell, the movable plate is fixedly connected to the inside of the shell, the connecting plate is fixedly connected to the end of the extension rod away from the shell, the splint is installed on the outer wall of the connecting plate, the rotating rod is rotatably connected to the outer wall of the splint, the rotating wheel is fixedly connected to the bottom end of the rotating rod, the bent rod is fixedly connected to the surface of the conveying member, and the frame is fixedly connected to the top end of the bent rod.

[0013] Preferably, the bottom end of the down-pressing rod passes through the shell and extends to the interior of the shell, the outer wall of the down-pressing rod is slidably connected to the inner wall of the shell that is penetrated, and one end of the extension rod passes through the outer wall of the shell and extends to the interior of the shell, and the outer wall of the extension rod is slidably connected to the inner wall of the shell that is penetrated.

[0014] By adopting the above technical solution, when the connecting member moves, the pressing rod can be driven by the connecting rod to slide inside the shell and compress the gas inside the shell, and the extension rod can slide inside the shell.

[0015] Preferably, one end of the extension rod extending into the interior of the shell is fixedly connected to the outer wall of the movable plate, the bottom of the clamp is slidably connected to the outer wall of the conveying member, the outer wall of the rotating wheel abuts against the outer wall of the workpiece, and the shell passes through the frame and is fixedly connected to the inner wall of the frame.

[0016] By adopting the above technical solution, after the air inside the shell is compressed by the downward pressure rod, it will push the auxiliary part and the movable plate, so that the movable plate pushes the clamping plate to move on the surface of the conveying part through the extension rod and the connecting plate. When the rotating wheel contacts the surface of the workpiece, it can limit the workpiece and reduce the friction between the surface of the workpiece and the rotating wheel. The bending rod and the frame can support the shell.

[0017] Preferably, the auxiliary component includes a stabilizing rod, a pushing plate and a second spring, the stabilizing rod is fixedly connected to the inner wall of the shell, the pushing plate is slidably connected to the inside of the shell, and the second spring is fixedly connected to the outer wall of the pushing plate.

[0018] Preferably, the stabilizing rod passes through the pushing plate and extends to the outside of the pushing plate, and is slidably connected to the inner wall of the pushing plate through which it passes. The side of the second spring away from the pushing plate is fixedly connected to the outer wall of the movable plate, and the thrust applied by the second spring to the pushing plate is less than the pressure applied by the one connecting member of the spring.

[0019] By adopting the above technical solution, the setting of the stabilizing rod can ensure that the push plate can maintain stable sliding under the push of compressed gas. When the push plate moves, the moving plate can be pushed to change its position by spring 2. When the thrust applied by spring 2 is less than the pressure applied by spring 1, the push plate will remain stable under the action of the compressed air inside the shell, avoiding the movement of the push plate when the distance between the splints is expanded, causing the compressed air to drive the connecting part to rise through the lower pressure rod and the connecting rod, resulting in the failure of the pressure roller to apply sufficient pressure on the surface of the workpiece.

[0020] The beneficial effects of the present invention are: 1. By installing a sliding rod, a connecting piece, a spring 1 and a pressure roller on the surface of the bracket, since the outer wall of the sliding rod is slidably connected to the push rod and the fixed piece respectively, the sliding rod can slide inside the push rod and the fixed piece, and since the two sides of the spring 1 are respectively connected to the bottom of the fixed piece and the top of the connecting piece, and the position of the fixed piece cannot be changed, the spring 1 will apply pressure to the connecting piece to ensure that the pressure roller applies sufficient downward pressure on the surface of the workpiece, thereby solving the problem that the existing pressure regulating device cannot flexibly and accurately adjust the pressure of the pressure roller due to wear and other problems during long-term use.

[0021] 2. By arranging a pressure rod, an extension rod and a clamping plate on the surface of the conveying part, when the connecting part descends, the pressure rod will be driven to move inside the shell through the connecting rod, and the gas inside the shell will be compressed. The compressed air will push the extension rod to move through the auxiliary part, so that the extension rod pushes the clamping plate to move through the connecting plate until the outer wall of the rotating wheel contacts the outer wall of the workpiece, thereby completing the clamping of the workpiece and ensuring the stability of the workpiece during the transportation of the conveying part. At the same time, the setting of the rotating wheel can reduce the friction between the workpiece and the clamping component during the movement of the workpiece, thereby ensuring the smooth transportation of the workpiece.

[0022] 3. By arranging a stabilizing rod and a second spring inside the shell, the high-pressure gas inside the shell will cause the push plate to move on the surface of the stabilizing rod while applying pressure to the second spring, so that the second spring pushes the extension rod to move through the moving plate. When the specifications of the workpiece change, the extension rod will be pushed to slide inside the shell through the clamping plate and the connecting plate, and pressure will be applied to the second spring through the moving plate. Since the downward pressure applied by the spring pair of connecting parts is greater than the pushing force of the second spring on the push plate, the second spring will not push the push plate to move when it is pushed and compressed by the moving plate, so it will not affect the pressing operation of the pressing roller on the workpiece. Therefore, the clamping plate can clamp and fix workpieces of different specifications through auxiliary parts. BRIEF DESCRIPTION OF THE DRAWINGS

The film coating machine 3 includes a bracket 301, a conveying member 302, a film coating roller 303 and a cutting member 304. The bracket 301 is fixedly connected to the top of the base 1, the conveying member 302 is installed on the outer wall of the bracket 301, the film coating roller 303 is rotatably connected to the top of the bracket 301, and the cutting member 304 is installed on the outer wall of the bracket 301. It also includes: The pressing component 4 is located on the outer wall of the bracket 301 and is used to ensure that sufficient pressure is applied to the protective film on the surface of the workpiece.

[0028] The clamping assembly 5 is located on the outer wall of the conveying member 302 , and the clamping assembly 5 is used to ensure that the workpiece remains stable during the transportation of the conveying member 302 .

[0029] The pressing assembly 4 includes a push rod 401, a fixing member 402, a sliding rod 403, a connecting member 404, a spring 405 and a pressing roller 406. The push rod 401 is fixedly connected to the outer wall of the bracket 301, the fixing member 402 is fixedly connected to the bottom of the push rod 401, the sliding rod 403 is installed at the bottom of the fixing member 402, the connecting member 404 is fixedly connected to the bottom end of the sliding rod 403, the spring 405 is arranged on the outside of the sliding rod 403, and the pressing roller 406 is rotatably connected to the outer wall of the connecting member 404.

[0030] It should be noted that: the top end of the slide bar 403 penetrates the fixing member 402 and the push rod 401, and extends to the top of the push rod 401, the outer wall of the slide bar 403 is slidably connected to the inner wall of the fixing member 402 and the inner wall of the push rod 401, the slide bar 403 can slide inside the fixing member 402 and the push rod 401, the top and bottom of the spring 405 are fixedly connected to the bottom of the fixing member 402 and the top of the connecting member 404 respectively, the existence of the spring 405 applies pressure to the pressing roller 406 through the connecting member 404, thereby ensuring that the surface of the pressing roller 406 is always in contact with the top of the workpiece and applying sufficient pressure to the workpiece, and the outer wall of the pressing roller 406 is in contact with the top of the workpiece placed on the surface of the conveying member 302.

[0031] By installing the sliding rod 403, the connecting piece 404, the spring 1 405 and the pressure roller 406 on the surface of the bracket 301, since the outer wall of the sliding rod 403 is slidably connected to the top rod 401 and the fixing piece 402 respectively, the sliding rod 403 can slide inside the top rod 401 and the fixing piece 402, and since the two sides of the spring 1 405 are respectively connected to the bottom of the fixing piece 402 and the top of the connecting piece 404, and the position of the fixing piece 402 cannot be changed, the spring 1 405 will apply pressure to the connecting piece 404 to ensure that the pressure roller 406 applies sufficient downward pressure on the workpiece surface, thereby solving the problem that the existing pressure regulating device cannot flexibly and accurately adjust the pressure of the pressure roller 406 due to wear and other problems during long-term use.

[0032] The connecting member 404 is moved by sliding so that it slides inside the fixing member 402 and the top rod 401 until the bottom of the spring 1 405 abuts against the top of the connecting member 404. At this time, the spring 1 405 applies pressure to the connecting member 404, so that the connecting member 404 drives the pressure roller 406 to apply pressure to the workpiece on the surface of the conveying member 302.

[0033] The clamping assembly 5 includes a shell 501, a connecting rod 502, a pressing rod 503, an auxiliary member 504, an extension rod 505, a movable plate 506, a connecting plate 507, a clamping plate 508, a rotating rod 509, a rotating wheel 510, a bending rod 511 and a frame 512. The shell 501 is arranged outside the conveying member 302, the connecting rod 502 is fixedly connected to the outer wall of the connecting member 404, the pressing rod 503 is fixedly connected to one end of the connecting rod 502, and the auxiliary member 504 is arranged inside the shell 501. The extension rod 505 is installed on the outer wall of the shell 501, the movable plate 506 is fixedly connected to the inside of the shell 501, the connecting plate 507 is fixedly connected to the end of the extension rod 505 away from the shell 501, the clamping plate 508 is installed on the outer wall of the connecting plate 507, the rotating rod 509 is rotatably connected to the outer wall of the clamping plate 508, the rotating wheel 510 is fixedly connected to the bottom end of the rotating rod 509, the bending rod 511 is fixedly connected to the surface of the conveying member 302, and the frame 512 is fixedly connected to the top of the bending rod 511.

[0034] It should be noted that: the bottom end of the pressing rod 503 passes through the shell 501 and extends to the inside of the shell 501, the outer wall of the pressing rod 503 is slidably connected with the inner wall of the shell 501 that is penetrated, and when the connecting member 404 moves, it can drive the pressing rod 503 to slide inside the shell 501 through the connecting rod 502 and compress the gas inside the shell 501, one end of the extension rod 505 passes through the outer wall of the shell 501 and extends to the inside of the shell 501, the outer wall of the extension rod 505 is slidably connected with the inner wall of the shell 501 that is penetrated, the extension rod 505 can slide inside the shell 501, and one end of the extension rod 505 extending to the inside of the shell 501 is connected to the outer wall of the movable plate 506 The bottom of the clamping plate 508 is fixedly connected and slidingly connected to the outer wall of the conveying member 302. After the air inside the shell 501 is compressed by the downward pressure rod 503, the air will be pushed through the auxiliary member 504 and the movable plate 506, so that the movable plate 506 pushes the clamping plate 508 to move on the surface of the conveying member 302 through the extension rod 505 and the connecting plate 507. The outer wall of the rotating wheel 510 abuts against the outer wall of the workpiece. When the rotating wheel 510 contacts the surface of the workpiece, it can limit the workpiece and reduce the friction between the surface of the workpiece and the rotating wheel 510. The shell 501 passes through the frame 512 and is fixedly connected to the inner wall of the frame 512. The bent rod 511 and the frame 512 can support the shell 501.

[0035] By arranging a pressing rod 503, an extension rod 505 and a clamping plate 508 on the surface of the conveying member 302, when the connecting member 404 descends, the pressing rod 503 will be driven to move inside the shell 501 through the connecting rod 502, and the gas inside the shell 501 will be compressed. The compressed air will push the extension rod 505 to move through the auxiliary member 504, so that the extension rod 505 pushes the clamping plate 508 to move through the connecting plate 507 until the outer wall of the rotating wheel 510 contacts the outer wall of the workpiece, thereby completing the clamping of the workpiece and ensuring the stability of the workpiece during the transportation of the conveying member 302. At the same time, the setting of the rotating wheel 510 can reduce the friction between the workpiece and the clamping component 5 during the movement of the workpiece, thereby ensuring the smooth transportation of the workpiece.

[0036] When the connecting member 404 descends, the pressing rod 503 will be driven to slide inside the shell 501 through the connecting rod 502. At this time, the pressing rod 503 will compress the gas inside the shell 501. When the compressed air is restored, it will push the auxiliary member 504 to move. The auxiliary member 504 pushes the extension rod 505 to move through the moving plate 506. When the extension rod 505 moves, it will push the clamping plate 508 to slide on the surface of the conveying member 302 through the connecting plate 507 until the outer wall of the rotating wheel 510 contacts the outer wall of the workpiece on the surface of the conveying member 302, thereby completing the clamping of the workpiece.

[0037] The auxiliary component 504 includes a stabilizing rod 5041 , a pushing plate 5042 and a second spring 5043 . The stabilizing rod 5041 is fixedly connected to the inner wall of the shell 501 , the pushing plate 5042 is slidably connected to the inside of the shell 501 , and the second spring 5043 is fixedly connected to the outer wall of the pushing plate 5042 .

[0038] It should be noted that the stabilizing rod 5041 penetrates the push plate 5042 and extends to the outside of the push plate 5042, and is slidably connected to the inner wall of the push plate 5042 penetrated by the stabilizing rod 5041. The setting of the stabilizing rod 5041 can ensure that the push plate 5042 can maintain stable sliding under the push of the compressed gas. The side of the second spring 5043 away from the push plate 5042 is fixedly connected to the outer wall of the moving plate 506. When the push plate 5042 moves, the moving plate 506 can be pushed by the second spring 5043 to change its position. 043 exerts a thrust on the push plate 5042 that is smaller than the pressure exerted by the spring 1 405 on the connecting piece 404. When the thrust exerted by the spring 2 5043 is smaller than the pressure exerted by the spring 1 405, the push plate 5042 will remain stable under the action of the compressed air inside the shell 501, thereby preventing the push plate 5042 from moving when the distance between the clamping plates 508 is expanded, causing the compressed air to drive the connecting piece 404 to rise through the lower pressure rod 503 and the connecting rod 502, resulting in the pressure roller 406 being unable to exert sufficient pressure on the surface of the workpiece.

[0039] By arranging a stabilizing rod 5041 and a second spring 5043 inside the shell 501, the high-pressure gas inside the shell 501 will cause the push plate 5042 to move on the surface of the stabilizing rod 5041 while applying pressure to the second spring 5043, so that the second spring 5043 pushes the extension rod 505 to move through the movable plate 506. When the specifications of the workpiece change, the extension rod 505 will be pushed to slide inside the shell 501 through the clamping plate 508 and the connecting plate 507, and pressure will be applied to the second spring 5043 through the movable plate 506. Since the downward pressure applied by the spring 1 405 on the connecting member 404 is greater than the pushing force of the second spring 5043 on the push plate 5042, the second spring 5043 will not push the push plate 5042 to move when it is pushed and compressed by the movable plate 506, and will not affect the pressing operation of the pressing roller 406 on the workpiece. Therefore, the clamping plate 508 can clamp and fix workpieces of different specifications through the auxiliary member 504.

[0040] When compressed air appears inside the shell 501, the compressed gas will apply a thrust to the lower pressure rod 503 and the push plate 5042 in order to restore the air pressure. Since the driving force of the lower pressure rod 503 is spring 1 405, and the pressure applied by spring 1 405 to the lower pressure rod 503 is greater than the gas pressure inside the shell 501, the compressed air cannot push the lower pressure rod 503 to move. At this time, the compressed air will apply a thrust to the push plate 5042, so that the push plate 5042 pushes the movable plate 506 to move through the spring 2 5043, and since the thrust of the spring 2 5043 is less than the pressure applied by the spring 1 405 on the lower pressure rod 503, when the distance between the clamping plates 508 is expanded, pressure will be applied to the spring 2 5043 through the movable plate 506, and the push plate 5042 cannot be pushed to perform secondary compression on the air inside the shell 501, thereby ensuring the downward pressure of the pressure roller 406 on the workpiece surface.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
