Description

Technical Field

[0001] The invention belongs to the technical field of profile film laminating equipment, and in particular relates to a film pressing mechanism of a profile film laminating machine and a film pressing method thereof. Background Art

[0002] Metal profiles such as aluminum profiles are commonly used industrial materials. Aluminum profiles are often used in the construction industry such as aluminum alloy doors and windows, building curtain walls, etc. Aluminum profiles have excellent machinability, but their surfaces are easily scratched during the processes of molding, cutting, drilling, and assembly. Components such as doors and windows, curtain walls, etc. require that the surface of aluminum profiles is smooth, flat, and scratch-free, so it is necessary to coat the surface of the profiles to protect their appearance quality.

[0003] The profile laminating machine is a commonly used laminating equipment, which uses a film unwinding mechanism, a film pressing mechanism, a film cutting mechanism, etc. to apply the film to the surface of the profile. The laminating machine needs to prepare three rolls of film to cover the bottom wall and the left and right side walls of the profile respectively. Before the film is applied, the worker needs to roll up the film and adjust the film tension. This process takes a lot of time, resulting in low film application efficiency. In addition, if the existing profile laminating machine has a slight shake in the film pressing action, it is easy to cause uneven film coating, often with bubbles or wrinkles, affecting the adhesion strength of the film on the profile. Summary of the invention

[0004] The object of the present invention is to provide a film pressing mechanism and a film pressing method of a profile film laminating machine, so as to solve the problems of low film laminating efficiency caused by roll laminating and unstable film pressing action causing bubbles or wrinkles.

[0014] Furthermore, it also includes a flattening component, which is located downstream of the film pressing component. The flattening component is used to eliminate bubbles and wrinkles on the film on the first side wall and the second side wall. The flattening component includes a swinging device and a first pressure plate and a second pressure plate connected to the swinging device. The first pressure plate and the second pressure plate are respectively located on the left and right sides of the profile. The swinging device can drive the first pressure plate and the second pressure plate to move in the same direction so that the film is evenly applied to the first side wall and the second side wall.

[0015] Preferably, the swing device includes a motor, a rocker arm, a first connecting rod, a first slide, a second connecting rod and a second slide, the motor is drivingly connected to the rocker arm, the left and right ends of the rocker arm are respectively hinged to the first connecting rod and the second connecting rod, the other end of the first connecting rod is hinged to the first waist-shaped hole on the first slide, and the first slide is fixedly connected to the first pressure plate; the other end of the second connecting rod is hinged to the second waist-shaped hole on the second slide, and the second slide is fixedly connected to the second pressure plate.

In addition, the bottom wall and the second side wall of the profile using this mechanism can share a roll of film, which shortens the time for rolling up the film material and adjusting the tension of the film material, improves the working efficiency, and also reduces the number of parts of the film laminating machine, making the equipment structure more compact.

[0026] The connecting rod is installed on the roller frame of the top pressing assembly of this mechanism, and the end of the connecting rod is installed with a pressing wheel. The pressing wheel rolls and rubs with the inner bottom surface of the profile. The pressing wheel prevents the right side of the profile from tilting upward due to the thrust of the second roller upward, ensuring the stability of the profile movement process and further improving the film sticking accuracy. The installation angle of the connecting rod can be adjusted to make the pressing wheel suitable for profiles of different thicknesses.

[0027] The leveling component of this mechanism can eliminate bubbles and wrinkles on the film on the first side wall and the second side wall, and improve the quality of the film. It drives the first pressing plate and the second pressing plate to move in the same direction through the swing device to evenly apply the film to the first side wall and the second side wall. The swing arm angle of this leveling component can be freely adjusted, which is suitable for profiles of different widths. The swing arm angle of this leveling component is locked by a motor. Compared with spring-type clamping parts, the clamping force fluctuation is small and the leveling effect is better. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] like Figures 1 to 8 As shown, this embodiment discloses a film pressing mechanism of a profile laminating machine, including a supporting assembly 10, an adjusting frame 20, a pressing assembly 30, a folding assembly 40, a film pressing assembly 50 and a flattening assembly 60.

[0048] Please refer to Figure 1 The support assembly 10 is used to support the long strip profile 70. The profile 70 of this embodiment includes a bottom wall 71 and a first side wall 72 and a second side wall 73 extending upward from the left and right sides of the bottom wall 71, respectively. The first side wall 72 is higher than the second side wall 73. The support assembly 10 includes a bearing seat 11 mounted on a frame 80 and support rollers 12 mounted horizontally on the bearing seat 11 at both ends. Multiple groups of support assemblies 10 are installed on the frame 80 at intervals to stably support the profile 70.

[0049] Please refer to Figure 2 The adjusting frame 20 is used to adjust the height of the top pressing assembly 30 or the inclination angle of the folding assembly 40. The adjusting frame 20 is semicircular, and the bottom of the adjusting frame 20 is fixedly mounted on the frame 80 by bolts. The adjusting frame 20 is provided with an arc hole 21 coaxial with the adjusting frame. The folding assembly 40 and the top pressing assembly 30 are respectively mounted on the front and rear sides of the adjusting frame.

[0050] The top pressure assembly 30 includes a first support rod 31 vertically mounted on the adjustment frame 20 and a first roller 32 mounted on the lower end of the first support rod 31. A screw and a sleeve 22 are mounted on the adjustment frame. The sleeve 22 is a semi-cylindrical barrel, and its inner diameter matches the diameter of the first screw. The sleeve 22 is locked on the adjustment frame by a screw and a nut. After the top of the first support rod 31 passes through the sleeve 22, the nut is locked to fasten the first support rod 31 to the adjustment frame 20. The installation height of the first support rod 31 is adjustable, and the first roller 32 rolls and rubs against the top of the first side wall 72 of the profile. Specifically, the bottom of the first support rod 31 is fixedly connected to the roller frame 33, and the first roller 32 is mounted on the roller frame 33. A V-shaped groove 34 coaxial with the first roller is provided on the circumference of the first roller 32. The V-shaped groove 34 limits the first side wall 72 in the left-right direction to prevent the profile from shaking left and right. Please refer to Figure 1 and Figure 2 A connecting rod 36 is installed on the right frame plate 35 of the roller frame 33 through a butterfly nut 37. The installation angle of the connecting rod 36 is adjustable. A pressure wheel 38 is installed at the end of the connecting rod 36. There is rolling friction between the pressure wheel 38 and the inner bottom surface of the profile 70. The pressure wheel 38 can prevent the right side of the profile from being pushed upward by the folding component 40, so that the profile 70 can be smoothly transported forward to ensure the accuracy of film pasting.

[0051] Please refer to Figure 2 The folding assembly 40 is located downstream of the bottom film unwinding drum of the film laminating machine. The right side of the bottom film on the bottom film unwinding drum extends horizontally out of the profile. The bottom film can simultaneously cover the bottom wall 71 and the second side wall 73 of the profile. The folding assembly 40 is used to extrude the partially extended bottom film obliquely upward to form a pre-folded edge 92, so as to facilitate the subsequent film pressing process to flatly press the pre-folded edge 92 onto the second side wall 73. The folding assembly 40 includes a second support rod 41 and a second roller 42 installed at the lower end of the second support rod 41. The upper end of the second support rod 41 is fastened to the arc hole 21 by bolts, and the lower end of the second support rod 41 is inclined toward the second side wall 73 of the profile, wherein the inclination angle of the second support rod 41 can be adjusted by changing its installation position in the arc hole to adapt to profiles of different widths. The second roller 42 can roll and rub against the connecting edge between the bottom wall 71 and the second side wall 73 to fold the right side of the bottom film 91 obliquely upward to form a profile as shown in the figure. Figure 3 A pre-folded edge 92 is shown.

[0052] Please refer to Figure 5 and Figure 6The film pressing assembly 50 is located downstream of the folding assembly 40. The film pressing assembly 50 includes a first side pressing wheel 51 and a second side pressing wheel 52 located on the left and right sides of the profile 70, respectively. The first side pressing wheel 51 and the second side pressing wheel 52 are respectively installed on the sliders 55 of the two translation screws 53. The left and right sides of the sliders 55 can slide along the guide rails on the screw seat respectively. By rotating the hand wheels 54 of the two translation screws 53, the positions of the first side pressing wheel 51 and the second side pressing wheel 52 are adjusted, so that the first side pressing wheel 51 presses the side film 93 against the first side wall 72, and the second side pressing wheel 52 presses the pre-folded edge 92 of the bottom film against the second side wall 73, so as to achieve the following. Figure 4 The coating effect shown.

[0053] Please refer to Figure 7 and Figure 8 The flattening assembly 60 is located downstream of the film pressing assembly 50. The flattening assembly 60 is used to eliminate bubbles and wrinkles on the film on the first side wall 72 and the second side wall 73. The flattening assembly 60 includes a swinging device and a first pressing plate 61 and a second pressing plate 62 connected to the swinging device. The first pressing plate 61 and the second pressing plate 62 are respectively located on the left and right sides of the profile 70. The swinging device can drive the first pressing plate 61 and the second pressing plate 62 to move in the same direction to flatly adhere the film to the first side wall 72 and the second side wall 73, squeeze out bubbles in the film, and remove wrinkles.

[0054] Specifically, the swing device includes a motor (not shown in the figure), a swing rod 63, a first connecting rod 64, a first slide 65, a second connecting rod 66 and a second slide 67. The motor is mounted on the motor frame, and the output shaft of the motor is connected to the central drive of the swing rod 63. The swing rod 63 is arranged horizontally, and the left and right ends of the swing rod 63 are respectively hinged to the first connecting rod 64 and the second connecting rod 66. The other end of the first connecting rod 64 is hinged in the first waist-shaped hole 68 on the first slide, and the first slide 65 is fixedly connected to the first pressing plate 61; the other end of the second connecting rod 66 is hinged in the second waist-shaped hole 68 on the second slide, and the second slide 67 is fixedly connected to the second pressing plate 62. The swing device also includes two groups of guide rods 69 fixedly mounted on the frame, and the guide rods 69 extend in the left and right directions. The first slide 65 and the second slide 67 are respectively mounted on the two groups of guide rods 69, and the first slide 65 and the second slide 67 can translate along the guide rods 69.

[0055] When the film on the side wall of the profile needs to be leveled, the motor drives the swing rod 63 to rotate counterclockwise, and the swing rod 63 drives the first connecting rod 64 and the second connecting rod 66 to rotate at the same time, wherein the other end of the first connecting rod 64 moves along the waist-shaped hole on the first slide 65 and pulls the first slide 65 to the right until the first pressing plate 61 presses the side film 93; the other end of the second connecting rod 66 moves along the waist-shaped hole on the second slide 67 and pulls the second slide 67 to the left until the second pressing plate 62 presses the pre-folded edge 92. When the profile moves forward, the first pressing plate 61 and the second pressing plate 62 press the film flat and squeeze out the bubbles in the film. After the profile is coated, the motor reverses to release the first pressing plate 61 and the second pressing plate 62.

[0056] The laminating method of the profile laminating machine includes the following steps:

[0057] The height of the pressing assembly 30 and the inclination angle of the folding assembly 40 are adjusted according to the size of the profile 70, so that the first roller 32 can roll and rub against the top of the first side wall 72 of the profile, and the second roller 42 can roll and rub against the connecting edge between the bottom wall 71 and the second side wall 73 of the profile;

[0058] Loosen the butterfly nut 37 and adjust the installation angle of the connecting rod 36 so that the pressure wheel 38 can roll and rub against the inner bottom surface of the profile 70;

[0059] Place the profile 70 horizontally on multiple groups of support assemblies 10 arranged at intervals, pull the end of the side film 93 out of the side film unwinding drum and stick it to the first side wall 72 of the profile, and pull the end of the bottom film 91 out of the bottom film unwinding drum and stick it to the second side wall 73 of the profile;

[0060] The support roller 12 of the support assembly 10 is driven by a driving member (such as a servo motor) to rotate and convey the profile 70 forward. When the profile 70 moves to the top pressing assembly and the folding assembly, the top pressing assembly 30 positions the top of the profile, and the folding assembly 40 folds the portion of the bottom film 91 extending from the right side of the profile obliquely upward to form a pre-folded edge 92.

[0061] When the profile 70 passes through the film pressing assembly 50, the first side pressing wheel 51 presses the side film 93 onto the first side wall 72, and the second side pressing wheel 52 presses the pre-folded edge 92 of the bottom film onto the second side wall 73;

[0062] When the profile 70 passes through the flattening assembly 60, the swing device rotates the swing rod 63, driving the first pressing plate 61 and the second pressing plate 62 to simultaneously press the side film 93 on the first side wall 72 and the pre-folded edge 92 on the second side wall 73 to eliminate bubbles and wrinkles on the coating.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
