Description

Technical Field

[0001] This invention relates to the field of aluminum foil coating technology, specifically to a mirror aluminum foil coating equipment and coating method. Background Technology

[0002] Mirror-finish aluminum foil, crafted with a unique process to create a mirror-like, smooth surface, combines the toughness of metal with excellent reflectivity. It is widely used in architectural decoration, packaging, and electronics, adding a refined texture to products. Single-sided lamination of mirror-finish aluminum foil protects its core mirror properties while retaining its original functional characteristics. The mirror side, being the core functional surface, is susceptible to scratches, oxidation, and oil contamination, which can cause it to lose its high reflectivity. Lamination forms a protective layer, isolating it from external damage and maintaining its mirror-like finish for a long time. The other side must retain its original metallic properties to meet the requirements of subsequent processing and assembly, such as bonding, adhesion, conductivity, and heat dissipation. Single-sided lamination also avoids the cost waste of double-sided lamination and prevents lamination of non-functional surfaces from affecting the adaptability of aluminum foil forming and lamination processes, thus meeting the practical application requirements of decoration, electronics, and packaging industries.

[0003] Chinese patent document CN221365860U discloses an aluminum foil coating device, including a support frame and a coating box. The upper part of the left side surface of the coating box is provided with a film inlet, and a film feeding post is placed directly opposite the film inlet. A pressing block is placed at the lower end of the film feeding post, and the block is connected to the lower extension boss. A drive motor is placed on the side of the coating box, and the drive motor is connected to a film receiving post on the back of the coating box. A fixed post head is provided at the other end of the film receiving post. The film receiving post is provided with a film outlet on the coating box. Clamping mechanisms are provided at both ends of the film feeding post, and a movable column is provided for fixing the fixed end of the film feeding post.

[0004] In use, the aluminum foil is first installed on the film feeding pile. Due to the special design of the movable column and the connecting column, disassembly is convenient. After the aluminum foil is installed, tighten the bolts on the clamping mechanism to fix the position of the aluminum foil on both sides. Then adjust the angle of the rotatable end block so that it is pressed against the clamping block. At this time, turn on the drive switch on the drive motor to make the device work. Under the action of the pulley, the film receiving pile begins to stretch the aluminum foil and apply sufficient tension. The internal film coating box begins to coat the items to be coated. The coated aluminum foil comes out from the film outlet under the stretch of the film receiving pile and is then rolled on the film receiving pile for collection.

[0005] However, the above-mentioned patent documents also have the following shortcomings: during the process of bonding and fixing the protective film and the mirror aluminum foil with hot melt adhesive, when the two undergo the pressing step, some hot melt adhesive is prone to overflow from the edge of the mirror aluminum foil, forming an overflow phenomenon. If these overflowing adhesives are not cleaned up in time, they will have an adverse effect on the subsequent processing or winding operation. Summary of the Invention

[0006] This invention provides a mirror aluminum foil coating equipment and coating method, aiming to solve the problem in related technologies where, during the pressing step between the protective film and the mirror aluminum foil, some hot melt adhesive easily overflows from the edge of the mirror aluminum foil, forming an overflow phenomenon. If this overflowing adhesive is not cleaned up in time, it will have an adverse effect on subsequent processing or winding operations.

[0007] The mirror aluminum foil coating equipment of the present invention includes a mounting frame, a lifting mechanism, an unwinding mechanism one, an unwinding mechanism two, a pressing mechanism, and an adhesive coating mechanism. The lifting mechanism, the unwinding mechanism two, the pressing mechanism, and the adhesive coating mechanism are all connected to the mounting frame. The unwinding mechanism one is mounted on the lifting mechanism. The equipment also includes two cutting mechanisms, which are respectively disposed on the front and rear sides of the coated mirror aluminum foil. Each cutting mechanism includes a contact belt, two drive rollers, a connecting frame, a wind source, a vertical plate, and a shearing component. The two drive rollers are rotatably connected to the pressing mechanism. The contact belt is driven between the two drive rollers and can contact the front or rear side of the coated mirror aluminum foil. The top of the contact belt is on the same horizontal plane as the upper surface of the mirror aluminum foil. The connecting frame is connected to the mounting frame. The wind source is mounted on the connecting frame and can generate wind to blow the overflowing hot melt adhesive to solidify the overflowing hot melt adhesive. The vertical plate is connected to the connecting frame and the shearing component is mounted on the vertical plate. The shearing component can cut the solidified hot melt adhesive from the coated mirror aluminum foil.

[0008] Beneficial effects: When laminating mirror aluminum foil, the rolled mirror aluminum foil and protective film are first installed on unwinding mechanism one and unwinding mechanism two, respectively. Then, the lifting mechanism is activated to raise unwinding mechanism one to the set height. Next, the mirror aluminum foil and protective film are pulled separately so that the mirror aluminum foil passes through the adhesive coating mechanism and the protective film covers the upper surface of the mirror aluminum foil. Then, the protective film and mirror aluminum foil are placed into the pressing mechanism. After completion, unwinding mechanism one, unwinding mechanism two, adhesive coating mechanism and pressing machine are activated. The structure consists of unwinding mechanism one and unwinding mechanism two, which unwind the mirror aluminum foil and the protective film respectively. The coating mechanism applies hot melt adhesive to the top surface of the mirror aluminum foil. The pressing mechanism presses the protective film and the mirror aluminum foil together. The hot melt adhesive that overflows from the edge of the mirror aluminum foil during the pressing operation is supported by a contact belt. Then, the overflowing hot melt adhesive is dried and cured by a wind source. Finally, the cured hot melt adhesive is cut off by a shearing component to avoid adverse effects on subsequent processing or winding operations.

[0009] Preferably, the outer sides of both drive rollers are provided with teeth arranged in a ring, and the inner side of the contact belt is provided with multiple tooth grooves that are adapted to the teeth on the two drive rollers. The contact belt is engaged and connected between the two drive rollers.

[0010] Its effect is to enhance the stability of the contact belt during operation through the meshing transmission between the contact belt and the two drive rollers.

[0011] Preferably, the upper inner side of the contact strip is provided with a flow guiding surface, and the contact strip is a metal strip.

[0012] Its effect is that the guide surface can direct the overflowing hot melt adhesive, preventing the hot melt adhesive from adhering to the front or back of the protective film.

[0013] Preferably, the vertical plate is provided with a guide groove, which is triangular in shape and has a long side, a first hypotenuse, and a second hypotenuse.

[0014] Preferably, the shearing component includes a moving part, a pushing frame, a telescopic part, a lifting part, and a cutter. The moving part is slidably connected in the guide groove, the pushing frame is sleeved on the front end of the moving part, the telescopic part is connected to the vertical plate, the telescopic end of the telescopic part is connected to the pushing frame, and the lifting part and the cutter are both mounted on the moving part.

[0015] Its effect is that when the telescopic part drives the push frame to move to the left, the push frame can push the moving part to slide in the inclined side of the guide groove, so that the moving part drives the lifting part and the cutter to tilt and move downward, thereby cutting the solidified hot melt adhesive by the cutter.

[0016] Preferably, the lifting part and the cutter are both slidably connected within the moving part, the cutter is rotatably connected to the lifting part, and a torsion spring is connected between the cutter and the lifting part, and an elastic part is connected between the lifting part and the moving part.

[0017] Preferably, the shearing member further includes a protrusion and a blocking part. The protrusion is connected to the lifting part and has an inclined surface. The blocking part is connected to the vertical plate and is located on the movement trajectory of the protrusion.

[0018] Its effect is as follows: when the moving part drives the lifting part to move downward along the inclined side, the inclined surface of the protrusion can pass through the blocking part, so that the lifting part can continue to move downward relative to the moving part and stretch the elastic part. When the lifting part continues to move downward relative to the moving part, it can drive the cutter to cut off the hot melt adhesive that has dried and solidified at the edge of the mirror aluminum foil. After the cutter separates from the moving part, the bottom of the cutter contacts the guide surface on the contact strip. At this time, when the lifting part continues to drive the cutter downward, the cutter can flip under the guidance of the guide surface and twist the torsion spring, so that the cutter can clean the solidified hot melt adhesive attached to the guide surface.

[0019] Preferably, the shearing component further includes a chip removal channel connected to the pressing mechanism.

[0020] Its effect is that the cured hot melt adhesive that has been cleaned can be discharged through the chip removal channel.

[0021] Preferably, the shearing member further includes a blocking member, which includes a blocking part and an elastic part two. The blocking part is slidably connected to the vertical plate, one end of the blocking part extends into the inclined side two, and the blocking part is provided with an inclined surface. The elastic part two is connected between the blocking part and the vertical plate.

[0022] Its effect is that when the push frame drives the moving part to move to the left along the second inclined side, the moving part can push the inclined surface of the blocking part to move the blocking part and compress the second elastic part. After the moving part passes the blocking part, the blocking part is reset under the action of the second elastic part, thereby blocking the second inclined side and preventing the moving part from passing the second inclined side again when the push frame drives the moving part to move to the right, so as to ensure that the moving part can operate stably.

[0023] The present invention also provides a method for coating mirror aluminum foil, which includes the following steps:

[0024] S1: Install the rolled mirror aluminum foil and protective film onto unwinding mechanism one and unwinding mechanism two respectively;

[0025] S2: Start the lifting mechanism to raise the unwinding mechanism to the set height;

[0026] S3: Pull the mirror aluminum foil and the protective film separately so that the mirror aluminum foil passes through the adhesive coating mechanism and the protective film covers the upper surface of the mirror aluminum foil, and place the protective film and the mirror aluminum foil into the pressing mechanism;

[0027] S4: Start the unwinding mechanism 1, unwinding mechanism 2, glue coating mechanism and pressing mechanism. Unwinding mechanism 1 and unwinding mechanism 2 unwind the mirror aluminum foil and the protective film respectively. The glue coating mechanism coats the top surface of the mirror aluminum foil with hot melt adhesive. The pressing mechanism performs the pressing operation on the protective film and the mirror aluminum foil.

[0028] S5: Start the drive between the contact belt and the two drive rollers, and the contact belt collects the overflowing hot melt adhesive;

[0029] S6: Activate the wind source to generate wind that blows towards the overflowing hot melt adhesive, causing the overflowing hot melt adhesive to solidify;

[0030] S7: Activate the shearing mechanism to cut off the cured hot melt adhesive.

[0031] Beneficial effects: When laminating mirror aluminum foil, the rolled mirror aluminum foil and protective film are first installed on unwinding mechanism one and unwinding mechanism two, respectively. Then, the lifting mechanism is activated to raise unwinding mechanism one to a set height. Subsequently, the mirror aluminum foil is pulled through the adhesive coating mechanism, while the protective film covers the upper surface of the mirror aluminum foil. Then, the two are placed into the pressing mechanism. After that, unwinding mechanism one, unwinding mechanism two, adhesive coating mechanism and pressing mechanism are activated. Unwinding mechanism one and two unwind the mirror aluminum foil and protective film respectively. The adhesive coating mechanism applies hot melt adhesive to the top surface of the mirror aluminum foil. The pressing mechanism presses the two together. For the hot melt adhesive that overflows from the edge of the mirror aluminum foil during pressing, it is supported by the contact belt and then dried and cured by the air source. Finally, the cured hot melt adhesive is cut off by the shearing component to prevent it from having an adverse effect on subsequent processing or winding operations.

[0032] The beneficial effects of this invention are:

[0033] 1. By moving synchronously with the mirror aluminum foil during the lamination process, the hot melt adhesive that overflows during the pressing operation of the protective film and mirror aluminum foil is supported by the contact belt. Then, the air source generates wind to blow the overflowing hot melt adhesive, thereby drying and curing the overflowing hot melt adhesive. Finally, the shearing component cuts off the cured hot melt adhesive to avoid adverse effects on subsequent processing or winding operations.

[0034] 2. The guide surface can guide the overflowing hot melt adhesive, preventing it from adhering to the front or back of the protective film.

[0035] 3. When the lifting part moves down, it can drive the cutter to cut off the hot melt adhesive that has dried and solidified at the edge of the mirror aluminum foil. After the cutter separates from the moving part, the bottom of the cutter contacts the guide surface on the contact strip. At this time, when the lifting part continues to drive the cutter down, the cutter can flip under the guidance of the guide surface and twist the torsion spring, so that the cutter can clean the solidified hot melt adhesive attached to the guide surface.

[0047] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0048] like Figures 1 to 9As shown, the mirror aluminum foil coating equipment of the present invention includes a mounting frame 1, a lifting mechanism 2, an unwinding mechanism 3, an unwinding mechanism 4, a pressing mechanism 5, a cutting mechanism 6, and an adhesive coating mechanism 7. The lifting mechanism 2, the unwinding mechanism 4, the pressing mechanism 5, the cutting mechanism 6, and the adhesive coating mechanism 7 are all connected to the mounting frame 1. The lifting mechanism 2 can lift and support the unwinding mechanism 3, which contains the mirror aluminum foil roll. The unwinding mechanism 3 can unwind the mirror aluminum foil roll. The unwound mirror aluminum foil can pass through the adhesive coating mechanism 7, where hot melt adhesive is applied to the side of the mirror aluminum foil to be coated. Mechanism 2 4 is equipped with a protective film roll. The protective film roll can be unwound by unwinding mechanism 2 4. The mirror aluminum foil and the protective film after being coated with adhesive can be pressed together by pressing mechanism 5. The hot melt adhesive coated on the mirror aluminum foil will bond the protective film to it. When pressing mechanism 5 presses the mirror aluminum foil and the protective film together, some hot melt adhesive will overflow from the edge of the mirror aluminum foil, resulting in adhesive overflow. Cutting mechanism 6 can air dry and cure the hot melt adhesive overflowing from the edge of the mirror aluminum foil and cut it off from the mirror aluminum foil to avoid adverse effects on subsequent processing or winding operations.

[0049] When laminating mirror aluminum foil, the rolled mirror aluminum foil and protective film are first installed on unwinding mechanism 3 and unwinding mechanism 4, respectively. Then, lifting mechanism 2 is activated to raise unwinding mechanism 3 to the set height. Next, the mirror aluminum foil and protective film are pulled separately so that the mirror aluminum foil passes through the adhesive coating mechanism 7 and the protective film covers the upper surface of the mirror aluminum foil. Then, the protective film and mirror aluminum foil are placed into the pressing mechanism 5. After completion, unwinding mechanism 3, unwinding mechanism 4, and adhesive coating machine are activated. The structure consists of a 7-component structure and a 5-component pressing mechanism. The unwinding mechanism 3 and the unwinding mechanism 4 unwind the mirror aluminum foil and the protective film respectively. The adhesive coating mechanism 7 coats the top surface of the mirror aluminum foil with hot melt adhesive. The pressing mechanism 5 presses the protective film and the mirror aluminum foil together. Finally, the cutting mechanism 6 is activated to air dry and cure the hot melt adhesive that overflows from the edge of the mirror aluminum foil. The cured hot melt adhesive is then cut off from the edge of the mirror aluminum foil to avoid adverse effects on subsequent processing or winding operations.

[0050] like Figures 1 to 4As shown, the pressing mechanism 5 includes a pressure roller 51, a support member 52, a rotating roller 53, a transmission belt 54, a cross plate 55, a servo motor one, and a servo motor two. The pressure roller 51 is rotatably connected to the mounting frame 1. The support member 52 is located below the pressure roller 51 and connected to the mounting frame 1. Two rotating rollers 53 are provided, both of which are rotatably connected inside the support member 52. Both rotating rollers 53 are provided with a set of teeth arranged in a ring. The transmission belt 54 is a metal belt, and the inner side of the transmission belt 54 is provided with multiple tooth grooves that are adapted to the tooth sets on the two rotating rollers 53, so that the transmission belt 54 is meshed and connected between the two rotating rollers 53. The cross plate 55 is connected inside the support member 52, and the top of the cross plate 55 contacts the inner top side of the transmission belt 54. The top of the transmission belt 54 is supported, and the protective film and mirror aluminum foil can pass through the gap between the pressure roller 51 and the transmission belt 54. The pressure roller 51 and the transmission belt 54 press them together. The transmission belt 54 can make the pressed mirror aluminum foil and protective film horizontal, so that the hot melt adhesive overflowing from the edge of the mirror aluminum foil can be dried and cut by the cutting mechanism 6. Servo motor 1 and servo motor 2 are respectively connected to the mounting frame 1 and the support member 52. Servo motor 1 is connected to the pressure roller 51 and can drive the pressure roller 51 to rotate. Servo motor 2 is connected to one of the rotating rollers 53 and can drive the transmission belt 54 and the two rotating rollers 53 to mesh and drive, thereby realizing the pressing operation of the protective film and mirror aluminum foil.

[0051] During the pressing operation of the protective film and the mirror aluminum foil coated with hot melt adhesive, servo motor one and servo motor two are started. Servo motor one drives the pressure roller 51 to rotate, and servo motor two drives the meshing transmission between the transmission belt 54 and the two rotating rollers 53. Thus, the pressure roller 51 and the transmission belt 54 press the protective film and the mirror aluminum foil coated with hot melt adhesive. After pressing, the mirror aluminum foil and the protective film continue to move to the left under the support of the transmission belt 54.

[0052] like Figures 1 to 9As shown, two cutting mechanisms 6 are configured, one on the front and one on the back of the pressed mirror aluminum foil. Each cutting mechanism 6 includes a drive roller 61, a contact belt 62, a guide surface 621, a connecting frame 63, a wind source 64, a vertical plate 65, a shearing component 66, a blocking component 67, a chip removal channel 68, and a DC motor. Two drive rollers 61 are vertically arranged and rotatably connected to the support component 52. The outer sides of both drive rollers 61 are provided with a ring-shaped set of teeth. The inner side of the contact belt 62 is provided with multiple tooth grooves that match the tooth sets on the two drive rollers 61. The contact belt 62 meshes and drives between the two drive rollers 61. The contact belts 62 on the two cutting mechanisms 6 respectively contact the pressed mirror aluminum foil. The aluminum foil is in contact with its front and back sides. The contact belt 62 can run synchronously with the transmission belt 54 so that the contact belt 62 and the coated mirror aluminum foil can run synchronously. The top of the contact belt 62 and the top of the pressed mirror aluminum foil are on the same horizontal plane so that the hot melt adhesive overflowing from the edge when the protective film and the mirror aluminum foil are pressed can adhere to the contact belt 62, preventing the overflowing hot melt adhesive from adhering to the front or back side of the mirror aluminum foil under its own weight. The upper inner side of the contact belt 62 is provided with a guide surface 621, which can guide the overflowing hot melt adhesive to prevent the hot melt adhesive from adhering to the front or back side of the protective film. The contact belt 62 is a metal belt. The DC motor is connected to the support member 52 and the DC motor is connected to one of the transmission rollers 61.

[0053] Continue to refer to Figures 1 to 9 As shown, the connecting frame 63 is connected to the mounting frame 1. Multiple wind sources 64 are provided, and all multiple wind sources 64 are installed on the mounting frame 1. Activating the wind source 64 can generate wind force to blow towards the overflowing hot melt adhesive, so as to promote the curing of the hot melt adhesive. The vertical plate 65 is connected to the connecting frame 63. The shearing piece 66 is installed on the vertical plate 65. The shearing piece 66 can cut the cured hot melt adhesive, thereby separating the overflowing hot melt adhesive from the coated mirror aluminum foil.

[0054] Continue to refer to Figures 1 to 9As shown, a guide groove 651 is provided on the vertical plate 65. The guide groove 651 is triangular in shape and has a long side, a first inclined side, and a second inclined side. The shearing component 66 includes a moving part 661, a pushing frame 662, a telescopic part 663, a lifting part 664, an elastic part 665, a cutter 666, a torsion spring 667, a protrusion 668, and a blocking part 669. The moving part 661 is slidably connected in the guide groove 651. The pushing frame 662 is sleeved on the front end of the moving part 661. The pushing frame 662 moves back and forth left and right. The kinetic energy drives the movable part 661 to slide within the guide groove 651. When the movable part 661 moves to the left, it is guided by the first hypotenuse to tilt and move downward. After the movable part 661 continues to move to the left and enters the second hypotenuse, it is guided by the second hypotenuse to tilt and move upward until it reaches the long side. Then, driven by the push frame 662, the movable part 661 moves horizontally along the long side to reset. A cylinder is provided on the movable part 661, and the movable part 661 slides through the cylinder. The cylinder is connected to the guide groove 651. The horizontal width of the angle between the long side and the first hypotenuse is greater than the diameter of the cylinder. This allows the cylinder to move down into the first hypotenuse and return to its original position after detaching from the long side, under the gravity of the moving part 661. The telescopic part 663 is connected to the vertical plate 65. The telescopic part 663 is a cylinder. The telescopic end of the telescopic part 663 is connected to the push frame 662. The telescopic part 663 can provide power for the left and right movement of the push frame 662. The lifting part 664 is slidably connected to the moving part 661. The elastic part 665 is... A spring, an elastic part 665, is connected between the lifting part 664 and the moving part 661. The cutter 666 is rotatably connected to the lifting part 664 and is limited to sliding connection with the moving part 661. A torsion spring 667 is connected between the cutter 666 and the lifting part 664 to drive the cutter 666 to reset. A protrusion 668 is connected to the lifting part 664 and has an inclined surface. A blocking part 669 is connected to the vertical plate 65 and is located on the moving trajectory of the protrusion 668.

[0055] Continue to refer to Figures 1 to 9As shown, when the moving part 661 drives the lifting part 664 to move downward along the inclined side, the inclined surface of the protrusion 668 can pass through the blocking part 669, so that the lifting part 664 continues to move downward on the moving part 661 and stretches the elastic part 665. When the lifting part 664 continues to move downward relative to the moving part 661, it can drive the cutter 666 to cut off the hot melt adhesive that has dried and solidified at the edge of the mirror aluminum foil. After the cutter 666 separates from the moving part 661, the bottom of the cutter 666 contacts the guide surface 621 on the contact strip 62. At this time, when the lifting part 664 continues to drive the cutter 666 downward, the cutter 666... Guided by the flow guide surface 621, the blade 666 can flip and twist the torsion spring 667, thereby cleaning the cured hot melt adhesive attached to the flow guide surface 621. After the protrusion 668 passes the blocking part 669, the lifting part 664 can be moved upward and reset by the elastic part 665, and the lifting part 664 can move the blade 666 upward. During this process, the torsion spring 667 can drive the blade 666 to reset until the blade 666 is limited and inserted into the moving part 661. The chip discharge channel 68 is connected to the support member 52, and the cured hot melt adhesive that has been cleaned can be discharged through the chip discharge channel 68.

[0056] Continue to refer to Figures 1 to 9 As shown, the barrier 67 includes a barrier portion 671 and an elastic portion 672. The barrier portion 671 is slidably connected to the vertical plate 65, and one end of the barrier portion 671 extends into the inclined side 2. An inclined surface is provided on the barrier portion 671. The elastic portion 672 is a spring and is connected between the barrier portion 671 and the vertical plate 65. When the push frame 662 drives the moving portion 661 to move to the left along the inclined side 2, the moving portion 661 can tilt upwards. When the moving part 661 passes the blocking part 671, the moving part 661 can push the inclined surface of the blocking part 671 to move the blocking part 671 and compress the elastic part 672. After the moving part 661 passes the blocking part 671, the blocking part 671 is reset under the action of the elastic part 672, thereby blocking the inclined side 2 to prevent the moving part 661 from passing the inclined side 2 again when the pushing frame 662 drives the moving part 661 to move to the right.

[0057] When cutting the overflowing hot melt adhesive, the contact belt 62, which moves synchronously with the drive belt 54, supports the overflowing hot melt adhesive. As the coated mirror aluminum foil moves to the left and the contact belt 62 moves, multiple air sources 64 generate airflow towards the hot melt adhesive, causing the overflowing hot melt adhesive to air dry and solidify. Then, the telescopic part 663 is activated to drive the push frame 662 to the left, so that the moving part 661 passes through the inclined side of the guide groove 651. This causes the moving part 661 to drive the lifting part 664 and the cutter 666 to move to the left and down synchronously with the coated mirror aluminum foil. The protrusion 668 on the lifting part 664 passes through the resistance... When the stop part 669 is in contact with the inclined surface on the protrusion 668, the protrusion 668 drives the lifting part 664 and the cutter 666 to continue to move downward on the moving part 661, and stretches the elastic part 665. At this time, the cutter 666 can cut the dried hot melt adhesive. After the blade of the cutter 666 contacts the guide surface 621 on the contact strip 62, the cutter 666 separates from the moving part 661. At this time, the cutter 666 continues to move downward and can flip and stick to the guide surface 621, thereby cleaning the cured hot melt adhesive attached to the guide surface 621. When the cutter 666 flips, it twists the torsion spring 667.

[0058] After the moving part 661 moves into the inclined side two of the guide groove 651, the protrusion 668 passes over the blocking part 669, and the elastic part 665 pulls the lifting part 664 to slide upward and reset on the moving part 661. When the lifting part 664 moves upward, it drives the cutter 666 to move upward. After the cutter 666 separates from the contact strip 62, the torsion spring 667 drives the cutter 666 to flip and reset until the lifting part 664 drives the cutter 666 to re-insert into the moving part 661. When the pushing frame 662 continues to move to the left and pushes the moving part 661 to tilt upward in the inclined side two, the leftward movement speed of the moving part 661 is greater than that of the mirror aluminum foil. The moving part 661 moves to the long side, and when it moves to the long side, it pushes the inclined surface of the blocking part 671 to move the blocking part 671 and compress the elastic part 672. After the moving part 661 passes the blocking part 671, the blocking part 671 is reset under the action of the elastic part 672, thereby blocking the inclined side 671 to prevent the moving part 661 from passing the inclined side 671 again when the pushing frame 662 drives the moving part 661 to move to the right. Finally, the telescopic part 663 is activated to drive the pushing frame 662 to move to the right and reset. The pushing frame 662 pushes the moving part 661 to move to the right and reset along the long side of the guide groove 651.

[0059] The present invention also provides a method for coating mirror aluminum foil, which includes the following steps:

[0060] S1: Install the rolled mirror aluminum foil and protective film onto unwinding mechanism 1 3 and unwinding mechanism 2 4 respectively;

[0061] S2: Start the lifting mechanism 2 to lift the unwinding mechanism 3 to the set height;

[0062] S3: Pull the mirror aluminum foil and the protective film separately so that the mirror aluminum foil passes through the adhesive coating mechanism 7 and the protective film covers the upper surface of the mirror aluminum foil, and place the protective film and the mirror aluminum foil into the pressing mechanism 5;

[0063] S4: Start the unwinding mechanism 1 3, unwinding mechanism 2 4, glue coating mechanism 7 and pressing mechanism 5. The unwinding mechanism 1 3 and unwinding mechanism 2 4 unwind the mirror aluminum foil and the protective film respectively. The glue coating mechanism 7 coats the top surface of the mirror aluminum foil with hot melt adhesive. The pressing mechanism 5 performs the pressing operation on the protective film and the mirror aluminum foil.

[0064] Specifically, the unwinding mechanism 3, unwinding mechanism 4, gluing mechanism 7, and pressing mechanism 5 are started. The unwinding mechanism 3 and unwinding mechanism 4 unwind the mirror aluminum foil and the protective film respectively. The gluing mechanism 7 applies hot melt adhesive to the top surface of the mirror aluminum foil. The servo motor 1 and servo motor 2 are started. The servo motor 1 drives the pressure roller 51 to rotate. The servo motor 2 drives the meshing transmission between the transmission belt 54 and the two rotating rollers 53. Thus, the pressure roller 51 and the transmission belt 54 press the protective film and the mirror aluminum foil coated with hot melt adhesive. The pressed mirror aluminum foil and the protective film continue to move to the left under the support of the transmission belt 54.

[0065] S5: Start the transmission between the contact belt 62 and the two drive rollers 61, and the contact belt 62 collects the overflowing hot melt adhesive.

[0066] Specifically, the DC motor is started to drive the meshing transmission between the contact belt 62 and the two drive rollers 61 so that the contact belt 62 moves synchronously with the mirror aluminum foil that moves to the left after being coated. During pressing, the hot melt adhesive overflowing from the edge of the mirror aluminum foil is guided by the guide surface 621 at the upper inner side of the contact belt 62.

[0067] S6: Activate the wind source 64 to generate wind that blows towards the overflowing hot melt adhesive, causing the overflowing hot melt adhesive to solidify;

[0068] S7: Activate the shearing component 66 to cut off the cured hot melt adhesive;

[0069] Specifically: the telescopic part 663 is activated, driving the push frame 662 to move to the left, so that the moving part 661 passes through the inclined side of the guide groove 651. This causes the moving part 661 to drive the lifting part 664 and the cutter 666 to move to the left and down simultaneously with the coated mirror aluminum foil. When the protrusion 668 on the lifting part 664 passes the blocking part 669, the blocking part 669 contacts the inclined surface on the protrusion 668, causing the protrusion 668 to drive the lifting part 664 and the cutter 666 to... The moving part 661 continues to move downward and stretches the elastic part 665. At this time, the cutter 666 can cut the dried hot melt adhesive. After the blade of the cutter 666 contacts the guide surface 621 on the contact strip 62, the cutter 666 separates from the moving part 661. At this time, the cutter 666 continues to move downward and can flip and stick to the guide surface 621, thereby cleaning the cured hot melt adhesive attached to the guide surface 621. When the cutter 666 flips, it twists the torsion spring 667.

[0070] After the moving part 661 moves into the inclined side two of the guide groove 651, the protrusion 668 passes over the blocking part 669, and the elastic part 665 pulls the lifting part 664 to slide upward and reset on the moving part 661. When the lifting part 664 moves upward, it drives the cutter 666 to move upward. After the cutter 666 separates from the contact strip 62, the torsion spring 667 drives the cutter 666 to flip and reset until the lifting part 664 drives the cutter 666 to re-insert into the moving part 661. When the pushing frame 662 continues to move to the left and pushes the moving part 661 to tilt upward in the inclined side two, the leftward movement speed of the moving part 661 is greater than that of the mirror aluminum foil. The moving part 661 moves to the long side, and when it moves to the long side, it pushes the inclined surface of the blocking part 671 to move the blocking part 671 and compress the elastic part 672. After the moving part 661 passes the blocking part 671, the blocking part 671 is reset under the action of the elastic part 672, thereby blocking the inclined side 671 to prevent the moving part 661 from passing the inclined side 671 again when the pushing frame 662 drives the moving part 661 to move to the right. Finally, the telescopic part 663 is activated to drive the pushing frame 662 to move to the right and reset. The pushing frame 662 pushes the moving part 661 to move to the right and reset along the long side of the guide groove 651.
