Description

Technical Field

[0001] The invention relates to the technical field of laser paper coating, in particular to a coating device for anti-counterfeiting laser transfer paper. Background Art

[0002] Generally, there are two kinds of laser films, one is OPP and the other is PET. The former can be directly pressed on it for laser printing, but the latter cannot. If you want to press laser images on PET base film, you must first apply a very thin special coating on the PET base film, and then press the laser images.

[0003] There is an invention patent for a laser transfer paper production coating device and method with a patent publication number of CN116856200A. In this patent, it is disclosed that "a V-shaped frame 6 is connected to the top of the support frame 2 at both ends of the load-bearing beam 1, and a nozzle 7 arranged in a V shape and located above the base paper 103 is arranged at the bottom of the V-shaped frame 6. The function of the nozzle 7 is to spray the upper surface of the base paper 103. The nozzle 7 is located in the space between the shielding synchronous belts 3 at both ends of the load-bearing beam 1. The nozzle 7 on the V-shaped frame 6 will form a V shape after spraying on the stationary base paper 103. This spraying structure can reduce the interference degree of the spray between the nozzles 7, reduce the thickness of the overlapping part after spraying in the lateral direction of the base paper 103, and make the thickness of the spray liquid covering the entire base paper 103 more uniform."

[0004] The above implementation method can indeed make the thickness of the spray liquid on the surface of the base paper more uniform, but the spacing between the positions of each nozzle is fixed, which makes the spray range of adjacent nozzles still have a certain intersection surface. After the overlapping spray covers the base paper, the coating thickness may be uneven, which will reduce the coating quality of the laser transfer paper.

DETAILED DESCRIPTION

[0029] 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.

[0030] See also Figure 1-9 The present invention provides a technical solution: a coating device for anti-counterfeiting laser transfer paper, comprising:

[0031] Embodiment 1,

[0032] The fuselage 1 has two rollers 2 disposed inside. The two rollers 2 are rotatably connected to the fuselage 1 and are powered by an external motor. Both ends of the laser paper are connected to other transmission shafts. The rollers 2 are used to transport the laser paper for displacement. The above is prior art and will not be described in detail.

[0033] In this scheme, a spray pipe 1 3 and a spray pipe 2 4 are provided above the fuselage 1, a plurality of nozzles 1 5 arranged at equal distances are provided below the spray pipe 3 and are interconnected, a plurality of nozzles 2 6 arranged at equal distances are provided below the spray pipe 2 4 and are interconnected, a bent pipe 1 7 is provided at the end of the spray pipe 3 and is fixedly connected to the bent pipe 7, a bent pipe 2 8 is provided on the inner wall of the bent pipe 7 and is slidably connected to the bent pipe 7, an end of the bent pipe 2 8 is located on the inner wall of the spray pipe 2 4 and is fixedly connected to the spray pipe 2 4, and an external spraying equipment can be connected to the spray pipe 2 4, thereby driving the coating to be discharged outward from the nozzles 1 5 and 2 6 at the same time.

[0034] The position of nozzle 1 5 is in the conveying direction of laser paper, at the center of two adjacent nozzles 2 6, the spacing between multiple nozzles 1 5 and multiple nozzles 2 6 is equal, and the ranges of liquid sprayed by nozzle 1 5 and nozzle 2 6 do not interfere with each other; since the multiple equally spaced nozzles 1 5 and nozzle 2 6 themselves also have a certain spacing, therefore, in the process of laser paper conveying driven by roller 2, the spraying ranges of multiple nozzles 1 5 and multiple nozzles 2 6 do not interfere with each other and complement each other, avoiding the mutual intersection of spraying, making the coating of laser paper more uniform, thereby improving the coating quality of laser transfer paper.

[0035] Furthermore, a connecting frame 9 is provided on the outer wall of the bending tube 2 8 and is fixedly connected thereto, and the bottom end of the connecting frame 9 is fixedly connected to the outer wall of the fuselage 1, and a correction plate 10 for shielding the coating is provided on the top of the fuselage 1, the correction plate 10 and the laser paper are perpendicular to each other, and there is a gap between the bottom end of the correction plate 10 and the surface of the laser paper, and this gap is the coating thickness of the laser paper, and an adjustment unit 11 for pushing the spray pipe 1 3 and the spray pipe 2 4 to move closer to and away from each other is provided on the side of the fuselage 1, and the correction plate 10 is driven to rise and fall through the adjustment unit 11, thereby increasing and decreasing the coating thickness of the laser paper, so that the coating thickness changes adaptively with the spraying coverage area of ​​the nozzle 1 5 and the nozzle 2 6, thereby improving the intelligence and applicability of the product, so that it can be automatically applied to laser paper coating with different thickness requirements.

[0036] The adjustment unit 11 includes a connecting rod 12 located on the outer wall of the bending tube 17, the inner wall of the connecting rod 12 is fixedly connected to the bending tube 17, a connecting rod 2 13 is provided at the end of the connecting rod 12 and is fixedly connected thereto, a flat gear 14 is provided below the connecting rod 2 13, a fixed shaft 15 is provided on the inner wall of the flat gear 14 and is rotatably connected thereto, an end of the fixed shaft 15 is fixedly connected to the outer wall of the fuselage 1, a wall body of the connecting rod 2 13 includes a tooth row 16 meshing with the flat gear 14, a vertical rod 17 is provided on one side of the flat gear 14, a wall body of the vertical rod 17 includes a tooth row 2 18 meshing with the flat gear 14, the vertical rod 17 is slidably connected to the fuselage 1, and the vertical rod A connecting rod 3 19 is provided at the end of 17 and is fixedly connected thereto, the bottom surface of the connecting rod 3 19 is fixedly connected to the correction plate 10, a fixing plate 20 is provided above the connecting rod 12 and is fixedly connected thereto, an electric push rod 40 is provided on one side of the fixing plate 20, the end of the electric push rod 40 is fixedly connected to the fixing plate 20, a fixing plate 21 is provided at the end of the electric push rod 40 and is fixedly connected thereto, and the side surface of the fixing plate 21 is fixedly connected to the outer wall of the fuselage 1; the electric push rod 40 can be controlled by the staff through an external program to push and retract its distance, thereby ensuring the accuracy of the rise or fall of the correction plate 10 and ensuring good coating quality.

[0037] When it is necessary to coat laser paper with a thicker coating, the staff can use the electric push rod 40 to make the fixing plate 20 drive the connecting rod 2 13 to move towards the direction close to the spray pipe 2 4, thereby driving the gear row 16 and the flat gear 14 to mesh with each other, and then the flat gear 14 drives the gear row 2 18 to mesh with each other. In this process, due to the transmission effect of the gear row 16 and the gear row 2 18 and the flat gear 14, the connecting rod 12 will drive the bending pipe 1 7 and the spray pipe 1 3 to approach the spray pipe 2 4, so that the spraying range of the nozzle 1 5 and the nozzle 2 6 overlaps, and the sprayed coating will become thicker. At the same time, the vertical rod 17 will also drive the connecting rod 3 19 and the correction plate 10 to lift up a short distance; due to the rise of the correction plate 10, the distance between the bottom end of the correction plate 10 and the laser paper is increased, so the coating thickness passing through the bottom end of the correction plate 10 will also increase, so that this equipment is automatically suitable for laser paper coating of different thicknesses.

[0038] Vice versa, when it is necessary to reduce the coating, the electric push rod 40 is used to push the fixed plate 20 to move in the opposite direction, so as to reduce the distance between the bottom end of the correction plate 10 and the surface of the laser paper. The resistance effect of the correction plate 10 on the coating can effectively ensure that the coating of the laser paper is within a qualified uniformity, which is beneficial to improve the overall quality of the coating.

[0039] In addition, a storage box 22 is provided inside the correction plate 10. The storage box 22 can slide inside the correction plate 10 and can be removed to recycle the coating inside the storage box 22. A rotating wheel 23 is provided on one side of the storage box 22. A shaft 24 is provided inside the rotating wheel 23 and is fixedly connected to the shaft 24. A fixing block 25 is provided on the outer wall of the shaft 24 and is rotatably connected to the shaft. One side of the fixing block 25 is fixedly connected to the correction plate 10. The shaft 24 and the roller 2 are mutually driven by a belt (the belt here is elastic. When the correction plate 10 is driven by the adjustment unit 11 to rise or fall a short distance, the roller 2 and the shaft 24 can still be driven). The rotating wheel 23 pushes the excess coating into the storage box 22. The bottom surface of the storage box 22 is in an inwardly inclined shape. The inclined bottom surface of the storage box 22 allows the excess coating to be better accumulated inside the storage box 22, thereby improving the recycling rate of the coating.

[0040] During the coating process of laser paper, the bottom area of ​​the correction plate 10 will block part of the accumulated paint, causing the paint to accumulate upward along the blocking area of ​​the correction plate 10. At the same time, the roller 2 will be transmitted through the belt shaft 24, thereby driving the rotating wheel 23 to rotate. The rotating wheel 23 will continuously push the accumulated paint and push the paint into the interior of the storage box 22, so that the staff can recycle the paint inside the storage box 22 and save paint resources.

[0041] According to the above embodiment, embodiment 2,

[0042] A drying chamber 26 is provided above the body 1 and is fixedly connected thereto. An air outlet box 27 is provided inside the drying chamber 26 and is fixedly connected thereto. The air outlet box 27 is provided with hot air by an external drying device and can be discharged vertically downward from the air outlet box 27, so that the coated laser paper can be pre-dried in time, providing favorable conditions for the subsequent drying and shaping process, thereby improving the overall coating quality.

[0043] Both ends of the air outlet box 27 are provided with auxiliary parts 28 for pushing the air body to perform lateral displacement. The auxiliary parts 28 include a bevel gear 29 located at the end of the roller shaft 2. The bevel gear 29 is fixedly connected to the roller shaft 2. A bevel gear 2 30 meshing with the bevel gear 29 is provided above the bevel gear 29. A shaft body 2 31 is provided inside the bevel gear 20 and is fixedly connected to the shaft body 2. A rotating plate 32 is provided on the outer wall of the shaft body 21 and is fixedly connected to the shaft body 21. The shaft body 21 is rotatably connected to the inner wall of the drying bin 26 through a fixed frame.

[0044] While the air outlet box 27 discharges the hot air downward, the roller 2 also drives the bevel gear 1 29 and the bevel gear 2 30 to engage and transmit, and then the shaft 2 31 drives the rotating plate 32 to rotate. The rotating plate 32 will generate horizontal wind when rotating, which pushes the hot air inside the drying chamber 26 to move horizontally on the surface of the laser paper, and cooperates with the vertical hot air discharged from the air outlet box 27, so that the hot air can be evenly laid on the surface of the laser paper, further improving the drying quality of the laser paper coating.

[0045] According to the above embodiment, embodiment 3,

[0046] Two fixing plates 33 are provided on the top of the drying bin 26 and are fixedly connected thereto. A shaft body 34 is provided on one side of the fixing plate 33 and is fixedly connected thereto. An exhaust box 35 is provided at the end of the shaft body 34 and is rotatably connected thereto. There are two exhaust boxes 35 in total. An elastic sheet 36 is provided between the two exhaust boxes 35. Both ends of the elastic sheet 36 are fixedly connected to the ends of the two exhaust boxes 35. An air pipe 37 is provided above the elastic sheet 36 and is fixedly connected thereto. Gas can enter the interior of the exhaust box 35 from the air pipe 37 and spread vertically downward. The air pipe 37 is connected to an external fan. A fixing strip 38 is provided on the outer wall of the air pipe 37 and is fixedly connected thereto. A top rod 39 is provided below the fixing strip 38. The bottom end of the top rod 39 is fixedly connected to the connecting rod 3 19.

[0047] In the coating work of normal coating, the gas discharged downward from the exhaust box 35 can help to spread the accumulated paint on the resisting surface of the correction plate 10, so as to make the surface coating of the laser paper more uniform; when facing a thicker coating, the paint accumulation in the central area of ​​the resisting surface of the correction plate 10 will be further increased, and the upwardly lifted correction plate 10 will drive the end of the push rod 39 to lift the fixing bar 38 upward, so that the fixing bar 38 drives the air pipe 37 and the elastic sheet 36 to rise. In the process of rising, since the ends of the two shafts 34 are rotatably connected to the exhaust box 35, and the elastic sheet 36 is elastic, the two exhaust boxes 35 will be closed toward the center, so that the exhaust range of the air body spreads from the central area of ​​the exhaust box 35 to both sides, so that the accumulated paint with a thicker thickness in the central area spreads to both sides, until the paint laying on the surface of the laser paper tends to be even, and then after being resisted by the correction plate 10, the uniformity of coating can be further improved.
