Description

Technical Field

[0001] This utility model belongs to the technical field of flattening devices, and in particular relates to a flattening device for the production of self-adhesive labels. Background Technology

[0002] As self-adhesive labels are applied to various fields such as food packaging, electronic components, and logistics traceability, the market demand for label materials has expanded from traditional paper to diverse types such as plastic film, metal foil, and synthetic paper. The thickness range has also extended from thin labels of 50μm to composite labels of more than 200μm. At the same time, the proportion of small-batch, multi-category orders continues to increase. The fixed structure of traditional flattening devices with "single specification adaptation" can no longer meet the needs of quickly switching production scenarios. For example, in the production of pharmaceutical labels, it is necessary to adapt to high-precision film materials and be compatible with thick anti-counterfeiting labels. Traditional equipment requires frequent replacement of roller support, which seriously restricts production flexibility.

[0003] However, existing flattening devices are difficult to adapt to labels of different sizes and materials during use. When it is necessary to switch to different labels, the machine must be stopped for a long time for component adjustment and debugging, which not only extends the production interval but also increases the labor operation cost. Utility Model Content

[0004] The purpose of this utility model is to provide a flattening device for self-adhesive label production. By setting a pressure unit, it solves the problem that existing flattening devices are difficult to adapt to labels of different sizes and materials during use. When it is necessary to switch to different labels, the machine needs to be stopped for a long time for component adjustment and debugging, which not only extends the production interval but also increases the labor operation cost.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a flattening device for producing self-adhesive labels, comprising a support frame and further comprising: a pressure section mounted on the support frame; two replacement sections, both mounted on the support frame; the pressure section includes a buffer assembly mounted on the support frame; and two hinge assemblies, both mounted on the support frame; the buffer assembly includes a groove formed on the support frame, and two sliders are provided on the front side of the support frame, the upper slider being slidably connected to the groove, and the lower slider being fixedly connected to the support frame, both sliders having a rotating shaft rotatably connected to their inner walls, and pistons fixedly connected to the sides of the two sliders that are close to each other, with pressure barrels fitted on the outer walls of the pistons, and venting devices provided on the pressure barrels, and a certain distance between the two pistons.

[0006] Furthermore, the replacement unit includes a flattening assembly mounted on a support plate frame; and an installation assembly disposed on the support plate frame. Both the flattening assembly and the installation assembly are located on a rotating shaft.

[0007] Furthermore, the hinge assembly includes two hinge blocks 1 that are fixedly connected to two sliders respectively. Each of the two hinge blocks 1 is hinged with a hinge rod. A hinge block 2 is hinged to one side of the two hinge rods that are close to each other. A telescopic component is provided on the pressure barrel. The two hinge assemblies are arranged in a mirror image. The telescopic component includes a telescopic rod that is fixedly connected to the outer wall of the pressure barrel. The left side of the telescopic rod is fixedly connected to the hinge block 2.

[0008] Furthermore, the flattening assembly includes a pressure roller sleeved on the outer wall of the rotating shaft, a fixing tube fixedly connected to the rear side of the pressure roller, and a plurality of limiting holes are provided on the rotating shaft, the limiting holes being distributed in a linear array on the rotating shaft.

[0009] Furthermore, the installation assembly includes a fixing ring sleeved on the outer wall of the fixing tube, and two limiting rods are provided on the fixing ring. The two limiting rods are fixedly connected to a fixing plate on the side that is far apart from each other. An elastic element is provided on the outer wall of the rotating shaft. The two limiting rods and the two fixing plates are arranged in a mirror image. The elastic element includes two springs respectively sleeved on the outer walls of the two limiting rods. The side of the two springs that is close to each other is fixedly connected to the fixing ring. The side of the two springs that is far apart from each other is fixedly connected to the two fixing plates respectively. The two springs are arranged in a mirror image.

[0010] This utility model has the following beneficial effects: 1. By setting up a pressure unit, during adjustment, the air extraction pipe fills the pressure tank with air to increase the air pressure inside the tank. The air pressure pushes the two pistons away from each other, thereby driving the upper slider to slide stably along the slide groove. The movement of the slider synchronously drives the displacement of the first hinge block. Through the transmission action of the hinge rod, the two second hinge blocks move closer to each other. The telescopic rod then adapts to the movement of the second hinge block, ultimately achieving synchronous and stable movement of the two rotating shafts and the connected pressure rollers away from or closer to each other. This not only accommodates the replacement needs of pressure rollers of different sizes and specifications, but also allows for precise adjustment of the distance between rollers for labels of different thicknesses, such as paper and plastic. It can adapt to various production scenarios without changing equipment, improving the versatility and applicability of the device. 2. By setting up a replacement section, during replacement, first manually pull the two fixing plates to move them away from each other. The fixing plates simultaneously drive the limit rod to slide along the limit hole. During this process, the spring is stretched and stores force. When the limit rod is completely disengaged from the limit hole, the fixing ring can be removed from the fixing tube. At this time, the pressure roller loses its fixed constraint and can be directly removed and replaced with a suitable model. After replacement, release the fixing plate. The spring elastically resets and pulls the fixing plate back into position. The limit rod is reinserted into the limit hole, completing the fixing of the pressure roller. The pressure roller can be replaced in just three simple steps: manual pulling, disassembly, and installation. This greatly shortens the equipment changeover time and lowers the operating threshold, making it especially suitable for scenarios where the label material is frequently changed on the production line.

[0011] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The upper slider 212 is slidably connected to the groove 211, and the lower slider 212 is fixedly connected to the support plate frame 111. A rotating shaft 213 is rotatably connected to the inner wall of each slider 212. A power source is provided on each rotating shaft 213 via a coupling to ensure that the rotational speed of the rotating shaft 213 matches the adhesive application speed. A piston 214 is fixedly connected to the side of each slider 212 that is close to each other. A pressure tank 215 is fitted onto the outer wall of each piston 214. The pressure tank 215 is equipped with an exhaust device, and there is a certain distance between the two pistons 214. The hinge assembly 22 includes two hinge blocks 221 that are fixedly connected to the two sliders 212 respectively. Each of the two hinge blocks 221 is hinged with a hinge rod 222. The two hinge rods 222 are hinged to each other on the side that is close to each other. The pressure tank 215 is equipped with a telescopic component. The two hinge assemblies 22 are arranged in a mirror image. The telescopic component includes a telescopic rod 224 that is fixedly connected to the outer wall of the pressure tank 215. The left side of the telescopic rod 224 is fixedly connected to the hinge block 223. By setting the pressure part 2, it can not only meet the replacement needs of pressure rollers of different sizes and specifications, but also accurately adjust the distance between the rollers for labels of different thicknesses such as paper and plastic. It can adapt to multiple production scenarios without changing equipment, thus improving the versatility and applicability of the device.

[0017] The replacement unit 3 includes a flattening assembly 31, which is mounted on a support plate frame 111; and an installation assembly 32, which is also mounted on the support plate frame 111. Both the flattening assembly 31 and the installation assembly 32 are located on a rotating shaft 213. The flattening assembly 31 includes a pressure roller 311 sleeved on the outer wall of the rotating shaft 213, with a fixing tube 312 fixedly connected to the rear side of the pressure roller 311. The rotating shaft 213 has several limiting holes 313 arranged in a linear array. The installation assembly 32 includes a fixing ring 321 sleeved on the outer wall of the fixing tube 312, with two limiting rods 322 on the fixing ring 321. The two limiting rods 322 are spaced far apart from each other. Each side is fixedly connected to a fixing plate 323. The outer wall of the rotating shaft 213 is provided with an elastic element. The two limit rods 322 and the two fixing plates 323 are arranged in a mirror image. The elastic element includes two springs 324 respectively sleeved on the outer wall of the two limit rods 322. The side of the two springs 324 that are close to each other is fixedly connected to the fixing ring 321. The side of the two springs 324 that are far from each other is fixedly connected to the two fixing plates 323 respectively. The two springs 324 are arranged in a mirror image. By setting the replacement part 3, the pressure roller can be replaced by only three simple steps: manual pulling, disassembly, and installation. This greatly shortens the equipment changeover time and lowers the operating threshold. It is especially suitable for scenarios where the label material is frequently changed on the production line.

[0018] A specific application of this embodiment is as follows: In use, different pressure rollers 311 are replaced according to the label material to be flattened. During replacement, the two fixing plates 323 are pulled apart. Simultaneously, the limiting rod 322 slides within the limiting hole 313. As it is pulled, the spring 324 is stretched. After the limiting rod 322 is completely disengaged from the limiting hole 313, the fixing ring 321 is removed from the fixing tube 312. At this point, the pressure roller 311 is unrestricted, allowing it to be removed and replaced with a suitable pressure roller 311. This achieves the effect of replacing the pressure roller 311 according to different materials. During replacement, the distance between the two rotating shafts 213 can be adjusted to accommodate different pressure rollers 311, and the two pressure rollers 311 can be adjusted according to the thickness of the label. When adjusting the distance, the suction pipe 216 is activated to inflate the pressure tank 215. At this time, the air pressure in the pressure tank 215 increases, and the two pistons 214 will move away from each other. When they move away from each other, they will cause the upper slider 212 to slide in the slide groove 211. When the two sliders 212 move, the corresponding hinge block 1 221 will move with them. When the hinge block 1 221 moves, it will cause the hinge rod 222 to move on the hinge block 223, and cause the two hinge blocks 223 to move closer to each other. At this time, the telescopic rod 224 will extend and retract to adapt to the movement of the hinge block 223. When the slider 212 slides, it will cause the rotating shaft 213 and the corresponding pressure roller 311 to move with it. As the two pressure rollers 311 continue to move away from each other, the effect of adjusting the pressure roller 311 can be achieved, thereby adapting to different label thicknesses.
