Description

Technical Field

[0002] The composite film bonding device is a device specially used to bond two or more layers of plastic composite films together through a specific process;

[0003] At present, according to the publication number CN219729991U, the name is a plastic composite film bonding device, comprising: a film feeding mechanism and a film collecting mechanism, the film feeding mechanism and the film collecting mechanism have the same structure; the film feeding mechanism comprises: a mounting frame; a first turntable frame, rotatably connected to one side of the mounting frame; a second turntable frame, rotatably connected to the other side of the mounting frame, and a plurality of unwinding rollers are rotatably connected between the first turntable frame and the second turntable frame;

[0004] The device is provided with a first turntable frame, a second turntable frame and a plurality of unwinding rollers, so that after the plastic composite film on one unwinding roller is bonded, it is only necessary to rotate the first turntable frame so that the remaining unwinding rollers can be replaced;

[0005] However, in actual application, since the composite film will inevitably be exposed to the air during the processing, the tiny dust particles in the air can easily adhere to the surface of the composite film, forming a thin layer of pollutants. This layer of pollutants is like a barrier, which seriously hinders the normal wetting and penetration process of the adhesive. The adhesive cannot fully penetrate into the tiny pores of the composite film material, resulting in weakened bonding force, which in turn affects the overall strength and durability of the composite film. In addition, during the bonding process, if the efficiency of unwinding and winding is inconsistent, the tension of the composite film will be insufficient, and wrinkles will appear during bonding, thereby reducing the overall bonding quality of the composite film.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] like Figures 1 to 11 As shown, the present invention provides a composite film bonding device, comprising a base 1 and a support plate 40, wherein a glue storage tank 2 is arranged inside the support plate 40, and an extrusion roller 3 located at the bottom end of the glue storage tank 2 is arranged at the bottom end of the base 1, and the number of the extrusion rollers 3 is two, and unwinding rollers 4 are arranged at both ends of the top of the base 1;

[0038] A cleaning mechanism is arranged at the bottom end of the support plate 40, and the cleaning mechanism includes a mounting plate 16, which is fixedly connected to the bottom end of the support plate 40, and the number of the mounting plates 16 is two, and two rotating rods 5 are rotatably connected to the opposite sides of the two mounting plates 16, and the opposite sides of the two rotating rods 5 are both rotatably connected to the mounting shell 6, and the mounting shell 6 is provided with a mounting block 7 inside, and a cleaning roller 8 is fixedly installed on the side of the mounting block 7 close to the center of the base 1;

[0039] A protective shell 9 is fixedly installed on the bottom end of the support plate 40, a gear 10 located inside the protective shell 9 is fixedly installed on one side of the rotating rod 5, a spring 11 is provided at the bottom end of the support plate 40, a connecting plate 12 is fixedly installed on one side of the spring 11, a rack 15 meshing with the gear 10 is fixedly installed on the bottom end of the connecting plate 12, a motor 13 is fixedly installed on one side of the outer surface of the protective shell 9, the output end of the motor 13 extends to the inside of the protective shell 9 and is fixedly installed with a cam 14.

[0040] The above scheme is adopted: the operator puts the composite films on the surfaces of the two unwinding rollers 4 between the two squeezing rollers 3 at the same time, and then the valve at the bottom of the glue storage tank 2 can be opened. At this time, the adhesive inside the glue storage tank 2 will flow between the two composite films, and then the squeezing rollers 3 can be driven to rotate, and the two composite films are adhered together through the squeezing of the squeezing rollers 3. After the adhesion is completed, the winding component at the top of the base 1 will rewind it and pull the composite film on the surface of the unwinding roller 4 to move;

[0041] During the movement of the composite film, the motor 13 can be driven to rotate the cam 14. During the rotation of the cam 14, it will contact the surface of the connecting plate 12 and push the connecting plate 12 to move. When the connecting plate 12 moves, the spring 11 will be compressed, and then the connecting plate 12 will drive the rack 15 to move. Because the rack 15 is meshed with the gear 10, the rotating rack 15 will drive the gear 10 to rotate, and the gear 10 will drive the rotating rod 5 to rotate. The rotating rod 5 will drive the mounting shell 6, the mounting block 7 and the cleaning roller 8 to rotate, and then the surface of the cleaning roller 8 will contact the composite film. The surface is in contact with the moving composite film, and the moving composite film will serve as a driving force to drive the cleaning roller 8 to rotate. Since the surface of the cleaning roller 8 is provided with adhesive paper, the two sides of the composite film can be cleaned at the same time on the rotating surface. Finally, the cleaning roller 8 is driven by a motor 13 to contact the moving composite film, so that both sides of the composite film can be cleaned, which helps the adhesive to better wetting and penetrate, thereby enhancing the bonding strength. In addition, the rotating cleaning roller 8 contacts the composite film, which can increase the tension of the composite film, avoid wrinkles during the bonding process, and improve the overall bonding quality of the composite film.

[0043] Slide rails 24 are fixedly installed on both sides of the inside of the extrusion roller 3. The surface of the slide rail 24 is slidably connected to a limit ring 25 located on the surface of the extrusion roller 3. The bottom end of the limit ring 25 is hinged to two hinged rods 26. The opposite sides of the two hinged rods 26 are hinged through a hinge block 27. A connecting belt 28 is fixedly installed on one side of the hinge block 27. A rotating wheel 29 is fixedly installed on one side of the gear 2 18, and one end of the connecting belt 28 is fixedly connected to the rotating wheel 29.

At this time, the sealing plate 121 will move inside the fixed shell 17, and the sealing plate 121 will drive the rack 20 to move. Because the rack 20 is meshed with the gear 2 18, the moving rack 20 will drive the gear 2 18 to rotate, and when the rack 20 moves, it will squeeze the spring 2 19, and then the gear 2 18 will drive the rotating wheel 29 to rotate. Since one end of the connecting belt 28 is fixedly connected to the rotating wheel 29, Furthermore, when the rotating wheel 29 rotates, the connecting belt 28 will be wrapped around its surface. At the same time, the connecting belt 28 will pull the hinge block 27 to move. Since one end of the two hinged rods 26 is hinged through the hinge block 27, when the hinge block 27 moves, it will pull the hinged rod 26 to rotate, and the hinged rod 26 will drive the limit ring 25 to move on the surface of the slide rail 24, and the limit ring 25 will move toward the two ends of the composite film and will contact both sides of the composite film, thereby limiting the moving direction of the composite film. Finally, the limit ring 25 is linked to move on the surface of the extrusion roller 3 by the rotating rod 5, so that the moving direction of the composite film can be limited, thereby improving the accuracy and consistency of bonding and reducing errors in the bonding process.

[0045] like Figure 5 , Figure 6 and Fig.10 As shown, it also includes: a fixing component, which is arranged on the surface of the mounting shell 6 and the mounting block 7, and the fixing component includes a limiting hole 30, the limiting hole 30 is opened on the surface of the mounting shell 6 and the mounting block 7, and a pin 31 is inserted into the limiting hole 30, one end of the pin 31 is fixedly installed with a connecting block 32, and the other end of the pin 31 is fixedly installed with a connecting disk 33.

At this time, the limiting of the mounting block 7 will be cancelled, and then the mounting block 7 can be taken out, and the unused mounting block 7 can be placed in the mounting shell 6, and the squeezing rollers 3 on the surfaces of the mounting shell 6 and the mounting block 7 are aligned. After alignment, the latch 31 and the connecting block 32 can be inserted The inside of the limiting hole 30, and then the connecting block 32 is passed through the inside of the limiting hole 30, and then the connecting disk 33 can be rotated, and the connecting disk 33 will drive the latch 31 and the connecting block 32 to rotate, and then the connecting block 32 will be misaligned with the limiting hole 30, and then the latch 31 can fix the mounting block 7 inside the mounting shell 6, and then the cleaning work can be continued, and finally the connecting disk 33 is driven to rotate so that the latch 31 and the connecting block 32 are aligned with the limiting hole 30, and then the cleaning roller 8 can be replaced without using auxiliary tools, thereby improving the convenience of the equipment.

[0047] like Figure 6 and Fig.10 As shown, a spring 34 is disposed inside the mounting shell 6 , and a push rod 35 is fixedly mounted on one end of the spring 34 .

[0048] The above scheme is adopted: through the design of spring three 34 and push rod 35, when the mounting block 7 is placed into the mounting shell 6, the surface of the mounting block 7 will contact the surface of the push rod 35, and will push the push rod 35 to move. When the push rod 35 moves, the spring three 34 will be compressed, and when the limit on the mounting block 7 is cancelled, the compressed spring three 34 will push the push rod 35 to move, and the push rod 35 will push the mounting block 7 out of the mounting shell 6, thereby improving the replacement efficiency.

[0049] like Figure 5 and Fig. 9 As shown, a driving assembly 36 is fixedly installed on one side of the glue storage tank 2, the output end of the driving assembly 36 extends to the interior of the glue storage tank 2, and a stirring paddle 37 is fixedly installed, and a support groove 38 is opened on one side of the mounting plate 16 close to the connecting plate 12, and a support block 39 is slidably connected inside the support groove 38, and one end of the support block 39 is fixedly connected to the connecting plate 12.

[0050] The above scheme is adopted: through the design of the driving component 36 and the stirring paddle 37, the driving component 36 can be driven to rotate the stirring paddle 37, and when the stirring paddle 37 rotates, the adhesive inside the glue storage tank 2 will be stirred, so that the adhesive will flow more smoothly, and through the design of the support groove 38 and the support block 39, when the connecting plate 12 moves, it will drive the support block 39 to slide inside the support groove 38, and the moving support block 39 can support the connecting plate 12 and the rack 15, thereby reducing the compound of the spring 11 and improving the service life of the equipment.

Through the design of the connecting disk 33, since the surface of the connecting disk 33 is provided with bumps and is rough in design, the friction between the palms can be increased, thereby facilitating the operator to rotate the connecting disk 33.

The limiting ring 25 is semicircular in design, and the limiting ring 25 is longitudinally symmetrically designed about the center of the extrusion roller 3 .

[0054] The above scheme is adopted: through the design of sealing plate 1 21 and sealing plate 2 23, since the surfaces of sealing plate 1 21 and sealing plate 2 23 are both in contact with the inner wall of fixed shell 17, the sealing property of fixed shell 17 is ensured, and air is prevented from being discharged from the inside of fixed shell 17 when sealing plate 23 moves, thereby ensuring that sealing plate 1 21 can move normally. Through the design of limiting ring 25, since limiting ring 25 is semicircular in design, limiting ring 25 will not interfere with the normal rotation of two extrusion rollers 3, and limiting ring 25 is symmetrically designed, thereby ensuring that limiting ring 25 can limit the moving direction of composite film.

[0055] The working principle and use process of the present invention:

[0056] First, the operator can put the composite film on the surface of the unwinding roller 4 between the two squeezing rollers 3, and then drive the squeezing roller 3 to rotate. During the rotation of the squeezing roller 3, the valve at the bottom of the glue storage tank 2 can be opened, and then the adhesive will flow from the bottom of the glue storage tank 2 to the connection of the composite film, and then it will be squeezed by the squeezing roller 3 to make it adhere together, and then the winding component can reel up the adhered composite film and pull the composite film to move;

[0057] During the movement of the composite film, the motor 13 can be driven to rotate the cam 14. During the rotation of the cam 14, the connecting plate 12 will be pushed to move. When the connecting plate 12 moves, the spring 11 will be compressed, and the connecting plate 12 will drive the rack 15 to move. The rack 15 will drive the gear 10 and the rotating rod 5 to rotate. The rotating rod 5 will drive the mounting shell 6, the mounting block 7 and the cleaning roller 8 to rotate. Then, the surface of the cleaning roller 8 will contact the surface of the composite film, and the moving composite film will be used as a driving force to drive the cleaning roller 8 to rotate. Since the surface of the cleaning roller 8 is provided with adhesive paper, both sides of the composite film can be cleaned at the same time on the rotating surface.

[0058] When the rack 15 moves, the connecting rod 22 will be linked to move, and the connecting rod 22 will drive the sealing plate 23 to move inside the fixed shell 17. During the movement, the air inside the fixed shell 17 will be squeezed. At this time, the sealing plate 121 and the connecting rod 22 will move inside the fixed shell 17, and the rack 20 will drive the gear 2 18 to rotate, and when the rack 20 moves, it will squeeze the spring 2 19, and then the gear 2 18 will drive the rotating wheel 29 to wrap the connecting belt 28 around its surface. At the same time, the connecting belt 28 will pull the hinge block 27 to move, and the hinge block 27 will pull the hinge rod 26 to rotate, and the hinge rod 26 will drive the limit ring 25 to move toward the two ends of the composite membrane, and will contact with both sides of the composite membrane, thereby limiting the moving direction of the composite membrane;

[0059] When the cleaning roller 8 needs to be replaced after being used for a long time, the connecting disk 33 can be rotated to rotate the latch pin 31 and the connecting block 32, and then the connecting block 32 can be aligned with the limiting hole 30, and then the latch pin 31 and the connecting block 32 can be pulled out from the inside of the limiting hole 30. At this time, the limit of the mounting block 7 will be cancelled, and then the compressed spring three 34 will push the push rod 35 to move, and the push rod 35 will push the mounting block 7 out of the mounting shell 6. At this time, the unused mounting block 7 can be placed in the mounting shell 6, and then the latch pin 31 and the connecting block 32 can be inserted into the limiting hole 30 again, and then the connecting block 32 can pass through the limiting hole 30, and then the connecting disk 33, the connecting block 32 and the latch pin 31 can be rotated to make the connecting block 32 misaligned with the limiting hole 30, and then the latch pin 31 can fix the mounting block 7 in the inside of the mounting shell 6, and then the cleaning work can be continued, and finally the operation process is completed.
