Description

Technical Field

[0001] This utility model relates to the field of aluminum foil embossing technology, and in particular to an adjustable aluminum foil surface embossing device. Background Technology

[0002] Aluminum foil is a hot stamping material made by directly rolling metallic aluminum into thin sheets. Its hot stamping effect is similar to that of pure silver foil, hence it is also called imitation silver foil. In the production and processing of aluminum foil film, in order to increase the aesthetics and practicality of the aluminum foil film, it is usually necessary to perform embossing treatment on its surface.

[0003] A search revealed that utility model CN220009303U discloses an embossing device for an aluminum foil embossing machine. However, this device has the following drawbacks: In actual use, when different patterns need to be embossed and the embossing rollers need to be replaced, the embossing rollers cannot be quickly replaced and installed, resulting in limited production flexibility and reduced production efficiency. Furthermore, in order to adapt to embossing aluminum foil of different thicknesses or to embossing patterns of different depths, adjusting the distance between the two rollers using a cylinder not only requires an additional air pressure source, increasing costs, but also easily leads to low accuracy. Therefore, we propose an adjustable aluminum foil film surface embossing device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the difficulty in quickly replacing and installing embossing rollers in traditional embossing devices, which limits production flexibility and reduces efficiency, and the need for additional air sources to adjust the roller spacing using cylinders, which increases costs and has low accuracy. Therefore, this invention proposes an adjustable aluminum foil embossing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable aluminum foil embossing device includes a base, a bracket fixedly mounted on the top of the base, a U-shaped frame slidably connected inside the bracket, a guide roller rotatably mounted on the inner wall of the adjacent sides of the U-shaped frame, and two openings on one side of the bracket, with the same embossing roller installed in each opening. The device also includes:

[0007] An adjustment assembly is used to adjust the gap between the guide roller and the embossing roller. The adjustment assembly includes two first rotating rods and two second rotating rods, and adjacent first rotating rods and second rotating rods are rotatably connected by a rotating shaft.

[0008] Two sets of fixing components are respectively set in the corresponding openings to fix the position of the embossing roller. The fixing components include a limiting block, which is slidably set in the opening.

[0009] In one possible design, the adjustment assembly further includes two slide grooves located on both sides of the support. The two ends of the U-shaped frame extend into the corresponding slide grooves and are slidably connected. Two first rotating rods are rotatably mounted on the inner wall of the bottom of the support, and two second rotating rods are rotatably mounted on the top of the U-shaped frame. Two first limiting plates are fixedly mounted on the inner wall of the bottom of the support, and two second limiting plates are fixedly mounted on the top of the U-shaped frame. Each of the two first limiting plates and the two second limiting plates has a first guide groove. A first sliding rod is slidably connected in each of the two first guide grooves on the two first limiting plates. The two first sliding rods are rotatably connected to the corresponding second rotating rods. The same second sliding rod is slidably connected in each of the two first guide grooves on the two second limiting plates. The second sliding rod rotatably passes through the two first rotating rods.

[0010] In one possible design, a first screw is rotatably connected inside the bracket, and a movable block is threaded through the first screw. The two sides of the movable block are fixedly connected to two first sliding rods respectively. A first motor is fixedly installed on one side of the bracket, and the output end of the first motor is fixedly connected to the first screw.

[0011] In one possible design, the fixing component also includes two bearings, which are fixedly sleeved on the embossing roller. The two bearings are respectively in contact with the inner wall of the corresponding opening. One side of the limiting block is in contact with the outer wall of the corresponding bearing. A limiting groove is opened on the bottom inner wall of the opening. A slider is slidably connected in the limiting groove. The sides of the limiting block and the slider that are close to each other are both set as inclined surfaces. The two inclined surfaces are in contact with each other. A second screw is rotatably connected to the bottom of the bracket. The top thread of the second screw extends into the interior of the limiting groove and is rotatably connected to the bottom of the slider. By pressing the inclined surface of the slider against the inclined surface of the limiting block, the slider moves into the opening and then comes into contact with and is pressed against the bearing on the embossing roller located in the opening, thus fixing the embossing roller in the opening.

[0012] In one possible design, two guide blocks are symmetrically arranged on the bottom inner wall of the opening. Two second guide grooves corresponding to the guide blocks are opened at the bottom of the limiting block. The two second guide grooves are slidably connected to the corresponding guide blocks. The guide blocks are used to prevent the limiting block from shifting during movement and thus prevent the bearing on the embossing roller from being effectively fixed.

[0013] In one possible design, a second motor is fixedly mounted on one side of the bracket via a mounting plate. The output end of the second motor is fixedly connected to a gearbox, and the gearbox is fixedly connected to the bracket via a frame. Both the output end of the gearbox and the embossing roller are fixedly fitted with sprockets, and the two sprockets are connected to the same chain for transmission.

[0014] In this application, firstly, when it is necessary to drive the embossing roller to rotate for embossing, the second motor is started, which drives the gear inside the gearbox to rotate. The output end of the gearbox is connected to the sprocket on the embossing roller through chain drive, thereby driving the embossing roller to rotate. The aluminum foil film passes between the guide roller and the embossing roller, and an embossed pattern is formed on the surface of the aluminum foil film.

[0015] When embossing aluminum foil of different thicknesses or when patterns of different depths need to be printed, the distance between the guide roller and the embossing roller can be adjusted. Specifically, by starting the first motor, the first screw is driven to rotate. Since the moving block is threadedly connected to the first screw, the rotation of the first screw will drive the moving block to move. The movement of the moving block will drive the two second rotating rods to move through the transmission action of the two first sliding rods. This will change the included angle between the adjacent first rotating rods and second rotating rods that are connected by a rotating shaft, thereby driving the U-shaped frame to move up and down in the slide groove. The movement of the U-shaped frame will drive the guide roller to move up and down, thereby changing the distance between the guide roller and the embossing roller.

[0016] When different patterns need to be embossed on aluminum foil, first remove the chain connected to the drive assembly on the embossing roller. Then, by rotating the two second screws, the slider moves downward in the limiting groove. The inclined surface of the slider is released from the squeezing of the inclined surface of the limiting block, so that the limiting block can be removed from the opening of the bracket, releasing the limiting block from fixing the position of the embossing roller, and thus the embossing roller can be quickly replaced.

[0017] When the position of the embossing roller needs to be fixed, place the limiting block at the opening of the bracket, and limit the movement direction by sliding the guide block through the second guide groove of the limiting block. Then, rotate the second screw in the opposite direction to make the slider move upward in the limiting groove. The movement of the slider will cause its inclined surface to press against the inclined surface of the limiting block, thereby moving the limiting block into the opening. When one side of the limiting block is in contact with the outer wall of the bearing on the embossing roller, the embossing roller can be fixed in the opening. Finally, connect the chain to the embossing roller and the drive assembly.

[0018] Beneficial effects: In this utility model, the adjustable aluminum foil film surface embossing device, with the setting of the adjustment component, can easily adjust the distance between the guide roller and the embossing roller, thereby adapting to aluminum foil films of different thicknesses for embossing treatment, improving the applicability and production efficiency of the device;

[0019] In this utility model, the adjustable aluminum foil film surface embossing device, with its fixed component, makes the installation and disassembly of the embossing roller convenient and quick. When the embossing roller needs to be replaced, the operation can be completed quickly, greatly improving production efficiency.

[0020] In this utility model, the adjustable aluminum foil film surface embossing device, through the guide block set on the inner wall of the bottom of the opening and the cooperation of the second guide groove on the slider, can effectively prevent the slider from deviating during the movement, and ensure the effectiveness and stability of the fixing component in fixing the embossing roller.

[0021] In this invention, the distance between the guide roller and the embossing roller can be easily adjusted by the adjustment component to adapt to embossing of aluminum foil films of different thicknesses, thereby improving the applicability and production efficiency of the device; the fixing component makes the embossing roller easy to install and disassemble, facilitating quick replacement and improving production efficiency; the guide block and the second guide groove cooperate to prevent the slider from shifting, ensuring the effectiveness and stability of the fixing component in fixing the embossing roller.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Example 1: Refer to Figure 1-5An embossing device includes components such as a base 1, a support 2, a U-shaped frame 3, a guide roller 4, and an embossing roller 5. The support 2 is fixedly mounted on the top of the base 1. Slide grooves 201 are formed on both sides of the support 2, and the same U-shaped frame 3 is slidably connected within the two slide grooves 201. A single guide roller 4 is rotatably mounted on the inner wall of the side of the U-shaped frame 3 closest to each other, for guiding aluminum foil film through. Two openings 202 are formed on one side of the support 2, and the same embossing roller 5 is mounted within both openings 202. Two bearings are fixedly fitted onto the embossing roller 5, and the two bearings respectively abut against the inner wall of the corresponding opening 202 to ensure stable rotation of the embossing roller 5.

[0030] To adjust the distance between the guide roller 4 and the embossing roller 5, an adjustment assembly is provided. The adjustment assembly includes two first rotating rods 6 and two second rotating rods 7. The two first rotating rods 6 are rotatably mounted on the inner bottom wall of the support 2, and the two second rotating rods 7 are rotatably mounted on the top of the U-shaped frame 3. Adjacent first rotating rods 6 and second rotating rods 7 are rotatably connected via a rotating shaft. Two first limiting plates 8 are fixedly mounted on the inner bottom wall of the support 2, and two second limiting plates 9 are fixedly mounted on the top of the U-shaped frame 3. Each of the first limiting plates 8 and second limiting plates 9 has a first guide groove for guiding the movement of the sliding rods. A first sliding rod 10 is slidably connected within each of the two first guide grooves on the two first limiting plates 8, and each first sliding rod 10 is rotatably connected to its corresponding second rotating rod 7. A single second sliding rod 21 is slidably connected within each of the two first guide grooves on the two second limiting plates 9, and the second sliding rod 21 rotatably passes through both first rotating rods 6. By changing the included angle between the first rotating rod 6 and the second rotating rod 7, which are connected by a rotating shaft, the U-shaped frame 3 can be driven to slide up and down in the slide groove 201, thereby adjusting the distance between the guide roller 4 and the embossing roller 5.

[0031] To facilitate height adjustment of the U-shaped frame 3, a first screw 12 is rotatably connected inside the support 2. A movable block 11 is threaded through the first screw 12, and both sides of the movable block 11 are fixedly connected to two first sliding rods 10. A first motor 13 is fixedly installed on one side of the support 2, and the output end of the first motor 13 is fixedly connected to the first screw 12. When the first motor 13 is started, it can drive the first screw 12 to rotate, thereby driving the movable block 11 to move along the length direction of the first screw 12, causing the position of the two first sliding rods 10 to change, causing the position of one end of the first rotating rod 6 connected to the two first sliding rods 10 to move, thereby changing the included angle between the first rotating rod 6 and the second rotating rod 7, and thus driving the U-shaped frame 3 to move up and down.

[0032] To ensure the embossing roller 5 is stably positioned within the opening 202, two sets of fixing components are provided. Each fixing component includes a limiting block 14, which is slidably positioned within the opening 202, with one side abutting against the outer wall of the corresponding bearing. A limiting groove 203 is formed on the bottom inner wall of the opening 202, and a slider 15 is slidably connected within the limiting groove 203. The sides of the limiting block 14 and the slider 15 that are close to each other are both sloped, and the two sloped surfaces abut against each other. A second screw 16 is rotatably connected to the bottom of the bracket 2, and the top of the second screw 16 extends threadedly into the limiting groove 203 and is rotatably connected to the bottom of the slider 15. When the second screw 16 is rotated, the slider 15 can be moved along the length of the limiting groove 203. The slider 15 moves into the opening 202 by pressing against the sloped surface of the limiting block 14, thereby abutting and pressing against the bearing on the embossing roller 5 within the opening 202, thus fixing the embossing roller 5 within the opening 202.

[0033] A drive assembly is provided to rotate the embossing roller 5. The drive assembly includes a second motor 17, which is fixedly mounted on one side of the bracket 2 via a mounting plate. A gearbox 18 is fixedly connected to the output end of the second motor 17, and the gearbox 18 is fixedly connected to the bracket 2 via a frame. Both the output end of the gearbox 18 and the embossing roller 5 are fitted with sprockets, and the two sprockets are connected to the same chain 19. When the second motor 17 starts, it drives the output end of the gearbox 18 to rotate, which in turn drives the embossing roller 5 to rotate via the chain 19, thus achieving the embossing process on the aluminum foil film.

[0034] This application can be used in the field of aluminum foil embossing technology, or in other fields applicable to this application.

[0035] Example 2: Reference Figure 2-5 An improvement upon Embodiment 1 is provided: an adjustable aluminum foil embossing device, applied in the field of aluminum foil embossing technology. To prevent the limiting block 14 from shifting during movement and failing to effectively fix the bearing on the embossing roller 5, two guide blocks 20 are symmetrically arranged on the bottom inner wall of the opening 202. Two second guide grooves corresponding to the guide blocks 20 are formed at the bottom of the limiting block 14, and the two second guide grooves are slidably connected to the corresponding guide blocks 20. By setting the guide blocks 20 and the second guide grooves, the stability of the limiting block 14 during movement can be ensured.

[0036] However, as is well known to those skilled in the art, the working principles and wiring methods of the first motor 13 and the second motor 17 are commonplace and are conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.
