Description

Technical Field

[0001] This utility model belongs to the field of IMD sheet printing technology, and in particular relates to a printing equipment for IMD sheet production. Background Technology

[0002] IMD technology is widely used in consumer electronics (such as mobile phone casings and smartwatch dials), automotive interiors (instrument panels and center consoles), medical devices and other fields. Its core material, IMD sheet, needs to be printed to achieve pattern transfer and functional coating (such as wear-resistant layer and light-shielding layer) superposition. Its material is usually PC plastic film.

[0003] Traditional IMD sheet printing equipment typically fixes both ends of the sheet onto a roll roller and a traction roller, respectively, and then lays it flat on a worktable for printing. However, during printing, the sheet laid flat on the worktable may experience wrinkles due to tension fluctuations, resulting in unsatisfactory final printing results. To address this, we have proposed a printing equipment for IMD sheet production. Utility Model Content

[0004] The purpose of this invention is to provide a printing device for IMD sheet production. By setting up a flattening mechanism, specifically by activating an electric push rod to extend, which drives two moving frames backward via a moving plate. Because the rotating block is hinged to the flattening box via a rotating shaft, and the moving frames are slidably limited by the annular groove at the top of the rotating block via a moving rod, the two rotating blocks rotate clockwise around the rotating shaft, pressing the pressing plate downward to flatten the IMD sheet. After printing, the electric push rod retracts, the rotating block rotates counterclockwise, and the pressing plate resets under the elastic force of several springs, releasing the sheet from fixation. This method can quickly and efficiently flatten the IMD sheet, avoiding wrinkles or stretching that affect the printing effect. It solves the problem that in existing IMD sheet production printing equipment, the sheet flattened on the worktable often wrinkles due to sheet tension fluctuations, leading to unsatisfactory final printing results.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0014] A lifting assembly is installed on the front and back of the worktable and is used to guide IMD sheets of different thicknesses.

[0015] The outer surfaces of the winding roller and the traction roller are each fixedly connected to two correction blocks. A motor is fixedly connected to the back of the traction roller. The front of the motor is fixedly connected to a support plate located on the rear right side. There are four sets of lifting components, with two sets distributed on the front of the worktable and the remaining two sets distributed on the back of the worktable.

[0016] Furthermore, an electric push rod is fixedly connected to the top of the bracket located on the front, and a movable plate is fixedly connected to the output end of the electric push rod by bolts. Two movable frames are fixedly connected to the back of the movable plate.

[0017] Both of the movable frames slide through the front of the flattened box and extend into its interior, and the two movable frames are distributed at both ends of the back of the movable plate.

[0018] Furthermore, the flattening box is provided with two rotating blocks inside, and each of the two rotating blocks is fixedly connected to a rotating shaft on the side of the two rotating blocks that are far apart from each other. The rotating blocks are rotatably connected to the flattening box through the rotating shaft.

[0019] The end of the rotating shaft away from the rotating block is fixedly connected to an anti-detachment ring, which is used to prevent the rotating block from falling off.

[0020] Furthermore, each of the two movable frames is fixedly connected to a movable rod on the side away from each other, and an annular groove is provided on the top of the rotating block, with the movable rod slidingly limited in cooperation with the annular groove;

[0021] The flattening box is fixedly connected to a fixing plate on both the left and right sides. Two springs are fixedly connected to the bottom of the fixing plate, and one end of the bottom of each spring is fixedly connected to the top of the pressing plate.

Because the rotating block is hinged to the flattening box via a rotating shaft, and the movable frame is slidably limited by the annular groove at the top of the rotating block via a moving rod, the two rotating blocks rotate clockwise around the rotating shaft, pressing the pressing plate downward to flatten the IMD sheet. After printing, the electric push rod retracts, the rotating block rotates counterclockwise, and the pressing plate resets under the action of several springs, releasing the fixation of the sheet. This method can quickly and efficiently flatten the IMD sheet, avoiding wrinkles or stretching that could affect the printing effect.

The height of the guide rollers is adjusted by a knob according to the sheet thickness: turning the knob clockwise moves the threaded rod upwards, while turning it counterclockwise moves it downwards, and the two U-shaped frames at both ends are adjusted synchronously. The other guide roller is adjusted in the same way. The correction blocks at both ends of the winding roller and the traction roller, together with the anti-deviation blocks at both ends of the guide rollers, achieve the limitation and anti-deviation of the IMD sheet.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0038] Please see Figures 1-6As shown, this utility model is a printing equipment for IMD sheet production, including a workbench 1, and further including: a flattening mechanism 2, which is disposed on the left side of the top of the workbench 1, and is used to flatten the IMD sheet; and a guiding mechanism 3, which is disposed on the top of the workbench 1, and is used to prevent the IMD sheet from shifting; wherein, a printing machine 11 is disposed on the left side of the top of the workbench 1, and a curing lamp 12 is installed at the center line of the top of the workbench 1. The leveling mechanism 2 includes two supports 21, with a leveling box 22 fixedly connected to one side of the two supports 21 that is close to each other. A pressing plate 23 is provided at the bottom of the leveling box 22. A moving component 24 is installed on the top of the support 21 located in front and is used to move the pressing plate 23 downward. The printing machine 11 is fixedly connected to the top of the support 21 located at the rear. Guide holes 221 are provided at each of the four corners of the leveling box 22. Guide rods 231 are fixedly connected to each of the four corners of the top of the pressing plate 23. The guide rods 231 slide and limit the movement of the guide holes 221. The guiding mechanism 3 includes four support plates 31. The two support plates 31 on the left are rotatably connected to a winding roller 32, and the two support plates 31 on the right are rotatably connected to a traction roller 33. The lifting assembly 34 is installed on the front and back of the worktable 1 and is used to guide IMD sheets of different thicknesses. The outer surfaces of the winding roller 32 and the traction roller 33 are fixedly connected to two correction blocks 321. The back of the traction roller 33 is fixedly connected to a motor 331. The front of the motor 331 is fixedly connected to the support plate 31 on the right rear side. There are four sets of lifting assemblies 34. Two sets of lifting assemblies 34 are distributed on the front of the worktable 1, and the remaining two sets of lifting assemblies 34 are distributed on the back of the worktable 1. An electric push rod 241 is fixedly connected to the top of the bracket 21 on the front. A movable plate 242 is fixedly connected to the output end of the electric push rod 241 by bolts. Two movable frames 243 are fixedly connected to the back of the movable plate 242. The two movable frames 243 slide through the front of the flattening box 22 and extend into its interior. The two movable frames 243 are distributed at both ends of the back of the movable plate 242. Two rotating blocks 245 are provided inside the flattening box 22. A rotating shaft 247 is fixedly connected to the side of the two rotating blocks 245 that is away from each other. The rotating blocks 245 are rotatably connected to the flattening box 22 through the rotating shaft 247. An anti-detachment ring is fixedly connected to the end of the rotating shaft 247 away from the rotating blocks 245. The anti-detachment ring at one end of the rotating shaft 247 is used to prevent the rotating blocks 245 from falling off.Two movable frames 243 are fixedly connected to movable rods 244 on opposite sides. An annular groove 246 is provided on the top of the rotating block 245, and the movable rods 244 and the annular groove 246 are slidably limited together. When the electric push rod 241 is activated, it extends, causing the two movable frames 243 to move backward via the movable plate 242. Because the rotating block 245 is hinged to the flattening box 22 via a rotating shaft 247, and the movable frames 243 are slidably limited by the movable rods 244 and the annular groove 246 on the top of the rotating block 245, the two rotating blocks 245 rotate clockwise around the rotating shaft 247, pressing the pressing plate 23 downward to flatten the IMD sheet, completing the printing process. After completion, the electric push rod 241 retracts, the rotating block 245 rotates counterclockwise, and the pressing plate 23 resets under the elastic force of several springs 252, releasing the fixation of the sheet. This method can quickly and efficiently flatten the IMD sheet, avoiding wrinkles or stretching that may affect the printing effect. The flattening box 22 has fixed plates 251 on both the left and right sides. Two springs 252 are fixedly connected to the bottom of the fixed plates 251, and one end of each spring 252 is fixedly connected to the top of the pressing plate 23. The four springs 252 can reset the pressing plate 23 through their own elastic force, preparing for the next flattening operation. The lifting assembly 34 includes two lifting slots 341, with a U-shaped frame 342 slidingly and limitingly fitted inside each slot 341. A threaded rod 343 is threadedly connected inside the U-shaped frame 342, and a knob 344 is fixedly connected to the bottom of the threaded rod 343. The top of the outer surface of the threaded rod 343 is rotatably connected to the worktable 1. One end of the IMD sheet is wound onto the winding roller 32, and the guide head passes through the bottom of two guide rollers 345 and is fixed to the outer ring of the traction roller 33. The height of the guide rollers 345 is adjusted according to the sheet thickness using the knob 344: rotating the knob 344 clockwise causes the threaded rod 343 to drive the U-shaped frame 342. The roller moves upwards, and rotates counterclockwise to move downwards. The two U-shaped frames 342 at both ends are adjusted synchronously, and the other guide roller 345 is adjusted in the same way. The correction blocks 321 at both ends of the winding roller 32 and the traction roller 33, together with the anti-deviation blocks 346 at both ends of the guide roller 345, realize the limiting and anti-deviation of the IMD sheet. The guide roller 345 is rotatably connected inside the two U-shaped frames 342. The anti-deviation blocks 346 are fixedly connected to both ends of the outer surface of the guide roller 345. The top of the threaded rod 343 is fixedly connected to the anti-detachment block. The anti-detachment block at the top of the threaded rod 343 is used to prevent the threaded rod 343 from falling and to ensure that it can work normally.

[0039] A specific application of this embodiment is as follows: In use, one end of the IMD sheet is wound onto the winding roller 32, and then the pre-reserved lead of the IMD sheet is passed through the bottom of the two guide rollers 345 and finally fixed to the outer ring of the traction roller 33. At this time, the height of the two guide rollers 345 is adjusted according to the thickness of the IMD sheet. Specifically, the knob 344 is turned clockwise, which drives the threaded rod 343 to rotate together. Since the threaded rod 343 is rotatably connected to the worktable 1 and the U-shaped frame 342 is slidably limited by the two lifting grooves 341, the U-shaped frame 342 moves upward. Turning the knob 344 counterclockwise moves the U-shaped frame upward. 342 moves down, and the height of the U-shaped frame 342 at both ends of the guide roller 345 is adjusted synchronously. The other guide roller 345 is adjusted in the same way. After the adjustment is completed, the top of the IMD sheet will be in close contact with the outer ring of the two guide rollers 345, but the bottom of the IMD sheet will have a gap with the top of the worktable 1 to prevent excessive pressure from being applied to the IMD sheet, which would prevent it from moving smoothly on the worktable 1. The correction blocks 321 at both ends of the winding roller 32 and the traction roller 33, as well as the anti-deviation blocks 346 at both ends of the two guide rollers 345, work together to limit the IMD sheet and prevent it from deviating.

[0040] Then, the electric push rod 241 is extended, driving the two moving frames 243 to move backward together via the moving plate 242. Since both rotating blocks 245 are rotatably connected to the flattening box 22 via the rotating shaft 247, and the moving frame 243 is slidably limited by the annular groove 246 on the top of the rotating block 245 via the moving rod 244, both rotating blocks 245 will rotate clockwise around the rotating shaft 247 as the axis. At this time, the rotating block 245 will press the pressing plate 23, causing it to move downward and flatten the IMD sheet, avoiding wrinkles or stretching deformation that would lead to poor printing results. At this time, the printing machine 11 is started, and its internal control system will control the printing. The printing plate moves down to contact the IMD sheet. The feeding system will transport the pigment ink in the ink cartridge into the printing plate through the conveying pipe to complete the printing operation. Then, the printing machine 11 controls the printing plate to move up and starts the electric push rod 241 to retract, so that the two rotating blocks 245 rotate counterclockwise around the rotating shaft 247 as the axis. At this time, the pressing plate 23 loses its compression. Several springs 252 reset the pressing plate 23 through their own elasticity, releasing the fixation on the IMD sheet. When the pressing plate 23 is raised and lowered, the guide rods 231 at its four corners slide and limit the guide holes 221 at the four corners of the flattening box 22, so that the pressing plate 23 can move vertically.

[0041] Then, start motor 331 to rotate counterclockwise, driving traction roller 33 to rotate together for winding, so that the IMD sheet moves to the right under curing lamp 12. At this time, turn on curing lamp 12 (Osram HTC 400-241) to cure the ink and prevent the pattern from being damaged during winding. Repeat this cycle to complete the continuous operation of IMD sheet.
