Description

Technical Field

[0001] This utility model relates to the field of aluminum foil technology, specifically to an adhesive coating device for aluminum foil surfaces. Background Technology

[0002] Aluminum foil is a thin sheet made of metallic aluminum with a purity of 99.5% or higher through a rolling process. Its thickness is usually less than 0.2 mm (some special applications, such as laminates, can be as thin as 7-15 micrometers). It is soft, has excellent ductility, and has a silvery-white luster. Because its hot stamping effect is similar to silver foil, it is also known as "fake silver foil".

[0003] A search revealed a Chinese patent with publication number CN219723573U, which discloses an adhesive coating device. The device includes a spray cylinder with a cylinder at its top, a telescopic rod at its bottom, and a piston at the bottom of the telescopic rod. The bottom of the spray cylinder is connected to a regulating valve and to the top of a spray frame. The spray frame is a hollow structure with no bottom surface, and a roller is fixed inside. Remaining adhesive can be squeezed out by downward pressure. The user can observe the process through a viewing window on one side and adjust the falling speed of the adhesive using the regulating valve at the bottom. Compared to existing structures, this device allows the user to adjust the discharge speed using the regulating valve at the bottom, and the cylinder at the top enables stable discharge and squeezes out any remaining adhesive in the cylinder, facilitating coating by the roller at the bottom.

[0004] While the above solution allows for adjustment of the discharge speed and facilitates coating by the bottom roller, the coating device in the aforementioned patent has difficulty controlling the discharge width of the adhesive. Since aluminum foil strips come in different widths, excessive discharge width leads to adhesive waste, while insufficient discharge width affects the uniformity of the adhesive on the aluminum foil strip surface. Therefore, we provide an adhesive coating device for aluminum foil surfaces to solve the above problems. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-7 As shown, this utility model provides a technical solution for an adhesive coating device for aluminum foil surfaces, including an adhesive funnel 1 and an aluminum foil guiding mechanism 20. Supporting vertical plates 21 are fixedly connected to both sides of the adhesive funnel 1. The purpose of setting the supporting vertical plates 21 is to effectively support the adhesive funnel 1, so that the adhesive funnel 1 is above the aluminum foil guiding mechanism 20, which is beneficial for the feeding operation. The supporting vertical plates 21 are fixedly connected to the upper surface of the aluminum foil guiding mechanism 20. The aluminum foil guiding mechanism 20 mainly includes a base plate, a support plate and a guide roller, which is used for moving the aluminum foil strip, so that the aluminum foil strip can move to a predetermined position, which is convenient for subsequent adhesive coating work.

[0027] A U-shaped frame 2 is fixedly connected to one side of the adhesive funnel 1, and a support frame 11 is fixedly connected to one side of the U-shaped frame 2. The cooperation between the U-shaped frame 2 and the support frame 11 ensures that the adhesive coating work is carried out smoothly. A DC motor 12 is fixedly connected to the top of the support frame 11, and a one-way lead screw 13 is fixedly connected to the output shaft of the DC motor 12. The purpose of setting the DC motor 12 is to effectively provide sufficient power support for the rotation of the one-way lead screw 13. The DC motor 12 is a known technology and will not be described in detail.

[0028] The outer circumferential surface of the one-way screw 13 is threadedly connected to the inner wall of the force-applying slider 14. The tight fit between the one-way screw 13 and the force-applying slider 14 allows the rotation of the one-way screw 13 to effectively drive the force-applying slider 14 to perform vertical lifting and lowering movements when the force-applying slider 14 is restricted. A force-bearing support plate 15 is rotatably connected to one side of the force-applying slider 14. One end of the force-bearing support plate 15 is rotatably connected to one side of the mounting block 16. The purpose of setting the force-bearing support plate 15 is to effectively support the mounting block 16, thereby enabling the mounting block 16 to support the roller guide plate 17.

[0029] Mounting block 16 is fixedly connected to one side of roller guide plate 17. Roller guide plate 17 and mounting block 16 are integrated and maintain a linkage effect. The other end of roller guide plate 17 is fixedly connected to positioning roller 18. The two ends of positioning roller 18 are rotatably connected to the inner wall of support frame 11. The positioning roller 18 causes roller guide plate 17 to rotate around positioning roller 18 as an axis. At this time, roller guide plate 17 makes arc motion. One end of roller guide plate 17 is rotatably connected to coating roller 19. Roller guide plate 17 and coating roller 19 maintain a linkage effect. Roller guide plate 17 will drive coating roller 19 to move, causing the position of coating roller 19 to change. Thus, coating roller 19 changes the spacing between aluminum foil strip and aluminum foil strip, thereby effectively controlling the coating thickness of adhesive on the surface of aluminum foil strip, while keeping the adhesive on the surface of aluminum foil strip uniform.

[0030] A DC motor 3 is fixedly connected to one side of the U-shaped frame 2. The output shaft of the DC motor 3 is fixedly connected to a synchronous pulley 4. The purpose of setting the DC motor 3 is to effectively provide sufficient power support for the rotation of the synchronous pulley 4. The DC motor 3 is a known technology and will not be described in detail.

[0031] The toothed grooves on the outer circumference of the synchronous pulley 4 mesh with the teeth of the synchronous belt 5. The tight fit between the synchronous pulley 4 and the synchronous belt 5 can effectively achieve the transmission effect. Through the design of its toothed grooves, there will be no slippage. The synchronous belt 5 is fixedly connected to the positioning block 6. The synchronous belt 5 will drive the positioning block 6 to move. Due to the reasonable distribution of the two positioning blocks 6, when the synchronous belt 5 moves, it can drive the two positioning blocks 6 to move synchronously, and the two positioning blocks 6 move in opposite directions.

[0032] A linkage plate 7 is fixedly connected to one side of the positioning block 6, and the positioning block 6 and the linkage plate 7 maintain a linkage effect. A linkage slider 9 is fixedly connected to one side of the linkage plate 7, and the linkage slider 9 is slidably connected to the other side of the U-shaped frame 2 through the guide rail 10. The tight fit between the linkage slider 9 and the guide rail 10 can effectively ensure the stability of the linkage plate 7 during movement and prevent it from falling off. A flow control plate 8 is fixedly connected to the other side of the linkage plate 7, and the linkage plate 7 and the flow control plate 8 maintain a linkage effect. The outer wall of the flow control plate 8 is slidably connected to the adhesive funnel 1. The setting of the flow control plate 8, by moving it, can control the width of the outlet of the adhesive funnel 1, thereby achieving the purpose of controlling the width of the adhesive discharge.

[0033] Working Principle: During use, the aluminum foil strip moves via an external traction device, passing through the outer circumference of the aluminum foil guide mechanism 20 and the pointing roller. At this time, the adhesive stored in the adhesive funnel 1 falls from the outlet onto the aluminum foil strip surface. The DC motor 12 is then activated, driving the one-way screw 13 to rotate. The force-bearing support plate 15, connected to the force-applying slider 14, is restricted by the roller guide plate 17 via the mounting block 16. Therefore, the rotation of the one-way screw 13 drives the force-applying slider 14 downwards. Since the roller guide plate 17 rotates around the positioning roller 18, the force-applying slider 14 can drive the roller guide plate 17, connected to the mounting block 16, through the force-bearing support plate 15, thereby changing the tilt angle of the roller guide plate 17. This causes the coating roller 19 to move synchronously, bringing it closer to the aluminum foil strip surface. As the aluminum foil strip continues to move, the coating roller 19 applies adhesive to the surface of the aluminum foil strip. The adhesive is smoothed to achieve a uniform coating. When the width of the aluminum foil strip changes, the DC motor 3 needs to be started to drive the synchronous wheel 4 to rotate. The synchronous belt 5 makes the two synchronous wheels 4 rotate synchronously. The movement of the synchronous belt 5 will drive the positioning block 6 to move. Since the two positioning blocks 6 are distributed vertically, the synchronous belt 5 will drive the two positioning blocks 6 to move synchronously and in opposite directions. At this time, the linkage plate 7 connected with the positioning block 6 will be restricted by the guide rail 10 through the linkage slider 9. Therefore, the positioning block 6 can stably drive the linkage plate 7 and the linkage slider 9 to move horizontally, thereby causing the flow control plate 8 to move synchronously. The distance between the two flow control plates 8 changes, thereby controlling the discharge width of the adhesive funnel 1, achieving the purpose of controlling the adhesive discharge width, so that the device can be adapted to aluminum foil strips of different widths.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
