Description

Technical Field

[0001] The invention belongs to the technical field of printing and coating, and in particular relates to a continuous printing and coating device. Background Art

[0002] Printing coating device is a device used to continuously apply coating or printed pattern on substrate. This device is widely used in packaging, printing, textile, electronics, construction and other industries, and can efficiently and evenly apply coating materials to the surface of substrate. Common substrates include paper, plastic film, metal foil, textile, wood, glass, etc.

[0003] After printing and coating materials on one side of a transparent substrate such as a plastic film, a light-curing lamp is usually used to cure the material on the substrate. However, a row of light-curing lamps are required on a traditional printing and coating device, and the substrate is stretched horizontally so that the material is continuously cured while being transported and rolled up. Not only is the curing efficiency low, but the device also occupies a large area.

[0004] In the prior art, for example, a Chinese invention patent with patent announcement number CN105058970B discloses a new printing coating machine. After the printing and coating of the substrate, the new printing coating machine continuously solidifies the material on the conveyed substrate through a first large drying device and a second large drying device stacked up and down. However, only the setting position of the drying device is changed. The energy of the drying device will be lost when passing through the thin substrate, and the utilization rate is low, and the curing efficiency is not increased. In addition, when conveying the substrate, both sides of the substrate need to bypass multiple rollers in turn to change direction so as to be conveyed to the bottom of different drying devices. Since at least one side of the substrate will be coated with material, the material coated on the substrate is easily damaged due to the friction of the rollers.

[0005] In view of the shortcomings of the above-mentioned prior art, a continuous printing and coating device is designed to overcome the shortcomings of the prior art and can efficiently fix the material coated on the substrate, occupy a small area, and avoid the material being affected by friction.

DETAILED DESCRIPTION The following is combined with Figure 1 To Attachment Figure 8 The principles and features of the present invention are described in detail with reference to the accompanying drawings and embodiments; the examples are only used to explain the present invention; they are not used to limit the scope of the present invention.

[0021] A continuous printing and coating device includes a frame 1, on which a reel 21 driven to rotate by two servo motors 20 and a reel 25 located on the left of the reel 21 are rotated. Two servo motors 20 are installed on the frame 1, and the output shafts of the two servo motors 20 are connected to the reel 21 and the reel 25 respectively. The reel 21 is suitable for supporting a substrate tube with a substrate rolled up. The reel 21 rotates counterclockwise to drive the substrate tube thereon to release the rolled substrate. The reel 25 is suitable for supporting a substrate tube for rolling up the substrate. The reel 25 rotates counterclockwise to drive the substrate tube thereon to roll up the substrate released by the substrate tube on the reel 21. A printing and coating module 3 is provided on the frame 1. The printing and coating module 3 includes a coating die head 34 for coating a substrate between the substrate tube on the reel 21 and the substrate tube on the reel 25. The coating die head 34 is a slit coating head.

[0022] Two groups of driven rollers 22 and two groups of active rollers 23 are arranged diagonally around the unwinding shaft 21. In this embodiment, the two groups of driven rollers 22 are respectively located at the upper left and lower right of the unwinding shaft 21, and the two groups of active rollers 23 are respectively located at the upper right and lower left of the unwinding shaft 21. The same group of driven rollers 22 and the same group of active rollers 23 respectively include a plurality of driven rollers 22 arranged in a direction gradually away from the unwinding shaft 21 and a plurality of active rollers 23 arranged in a direction gradually away from the unwinding shaft 21. There are three active rollers 23 in the same group of driven rollers 22, and there are three active rollers 23 in the same group of active rollers 23. When in use, the end of the substrate wound by the substrate tube on the unwinding shaft 21 is pulled upward and rotated counterclockwise from near to far in turn around the upper left driven roller 22, the lower left active roller 23, the lower right driven roller 22 and the upper right active roller 23, and then around the next driven roller 22 at a further distance in the upper left, so that the substrate is reciprocated to extend in a square spiral away from the unwinding shaft 21. Figure 3 At this time, only the inner side of the substrate is supported by contact, and the coating die 34 can coat the material on the outer side of the substrate, so that the material on the outer side of the substrate is not damaged by friction. A limiting roller 24 rotates on the frame seat 1, and the limiting roller 24 is located between the unwinding shaft 21 and a driven roller 22 closest to the unwinding shaft 21. Initially, the substrate pulled out by the substrate tube on the unwinding shaft 21 is pre-circled around the upper side of the limiting roller 24 and then around the driven roller 22 closest to the upper left. The coating die 34 is located between the limiting roller 24 and the driven roller 22, so as to utilize a section of the path when the substrate is pulled out maintained by the limiting roller 24 and the driven roller 22. Even if the substrate wound by the substrate tube on the unwinding shaft 21 becomes less and less, it will not affect the coating of the substrate by the coating die 34.

[0023] The frame seat 1 is provided with two groups of driven rollers 26 and two groups of active rollers 27 which are diagonally distributed with the winding shaft 25 as the center. In this embodiment, the two groups of driven rollers 26 are respectively located at the upper right and lower left of the winding shaft 25, and the two groups of active rollers 27 are respectively located at the upper left and lower right of the winding shaft 25. The same group of driven rollers 26 and the same group of active rollers 27 respectively include a plurality of driven rollers 26 and a plurality of active rollers 27 which are arranged in a direction gradually away from the winding shaft 25. The same group of driven rollers 26 and the same group of active rollers 27 respectively include a plurality of driven rollers 26 and a plurality of active rollers 27 which are arranged in a direction gradually away from the winding shaft 25. 6 has three driven rollers 26 in total, and the same group of active rollers 27 has three active rollers 27 in total. When in use, when the substrate in a square spiral state pulled out by the substrate tube on the unwinding shaft 21 completes the operation of surrounding the upper left driven roller 1 22, the substrate can be pulled out to the left and counterclockwise from far to near in turn around the upper left active roller 27, the lower left driven roller 26, the lower right active roller 27 and the upper right driven roller 26, and then around the next active roller 27 at a farther distance in the upper left, so that the substrate is reciprocated to extend in a square spiral state close to the winding shaft 25 as shown in FIG. Figure 3 At this time, only the inner side of the substrate is still supported by contact, and the material on the outer side of the substrate is still not affected by friction. The end of the substrate is finally pulled to the substrate tube on the winding shaft 25 for winding.

[0024] A light-curing lamp group 4 is installed on the frame 1 near the unwinding shaft 21 and the winding shaft 25. Since the substrate is in a square spiral shape, the energy of the light-curing lamp group 4 can pass through the substrate to simultaneously cure multiple layers of the substrate, thereby improving the utilization rate and curing efficiency. In addition, it should be explained that in actual use, the substrate can also not completely surround all the driven rollers 22 and the active rollers 23, and the substrate can be surrounded by the driven rollers 26 and the active rollers 27 at the corresponding positions, thereby narrowing the range surrounded by the substrate, adapting to different situations and substrates of different lengths, and diversifying the use methods. It is not necessary for the substrate to surround the complete range, and the coating, winding and curing operations of the substrate are guaranteed.

[0025] The printing coating module 3 also includes two front and rear opposite brackets 31 connected to the frame seat 1, a rotating shaft 32 is rotated between the lower parts of the two brackets 31, and the front and rear ends of the rotating shaft 32 are both rotated with rotating arms 33, and the coating die head 34 is installed between the sides of the two rotating arms 33 close to each other, so that the rotating arm 33 drives the coating die head 34 to swing downward, so as to adjust the adhesion force of the coating die head 34 on the substrate when coating. On the contrary, the rotating arm 33 drives the coating die head 34 to swing upward to release the substrate. The upper parts of the two brackets 31 are both rotated with cylinders 35, and the telescopic rods of the two cylinders 35 are respectively connected to the two rotating arms 33 for rotation. When the telescopic rod of the cylinder 35 is extended, the rotating arm 33 will rotate and drive the coating die head 34 to swing upward. When the telescopic rod of the cylinder 35 is retracted, the rotating arm 33 will rotate in the opposite direction and drive the coating die head 34 to swing downward.

[0026] The light curing lamp group 4 includes a light curing lamp 1 41 and a light curing lamp 2 42. Four light curing lamps 1 41 are installed at positions near the unwinding shaft 21 and near the winding shaft 25 on the frame 1 for curing the material coated on the substrate with light. The light curing lamp 1 41 near the unwinding shaft 21 on the frame 1 is located between the outermost driven roller 1 22 and the driving roller 1 23, and the light irradiation direction of the light curing lamp 1 41 is toward the unwinding shaft 21. The light curing lamp 1 41 near the winding shaft 25 on the frame 1 is located between the outermost driven roller 26 and the driving roller 27, and the light irradiation direction of the light curing lamp 1 41 is toward the winding shaft 25. The multiple light curing lamps 1 41 are used to cure the multi-layer substrates surrounded by the multiple driven rollers 1 22 and the driving roller 1 23 and the multi-layer substrates surrounded by the multiple driven rollers 26 and the driving roller 27. The material is continuously light-cured; four light-curing lamps 42 for light-curing the material coated on the substrate are installed at positions near the unwinding shaft 21 and the winding shaft 25 on the frame seat 1.

The light-curing lamp 42 near the winding shaft 25 on the frame seat 1 is located between the outermost driven roller 26 and the active roller 27, and the light-irradiating direction of the light-curing lamp 42 is away from the winding shaft 25. The working principle of the light-curing lamp 42 is the same as that of the light-curing lamp 41. On the basis of the light-curing lamp 41, the light-curing lamp 42 is used to surround the multi-layer substrate to perform light-curing on both sides of the substrate respectively, thereby improving the curing effect and curing efficiency.

[0027] The light curing lamp assembly 4 also includes a light curing lamp 3 43 installed on the frame 1 . The light curing lamp 3 43 is close to the coating die 34 . The light curing lamp 3 43 is used to perform preliminary light curing operation on the substrate just coated by the coating die 34 .

[0028] It also includes a vertical plate 11 connected to the frame seat 1, the vertical plate 11 separates the unwinding shaft 21 and the winding shaft 25, the light curing lamp group 4 close to the winding shaft 25 and the light curing lamp group 4 close to the unwinding shaft 21 are respectively located on the left and right sides of the vertical plate 11, so that the light curing operations of different light curing lamp groups 4 do not affect each other; the vertical plate 11 is provided with a through hole suitable for the substrate to pass through, so that the substrate wound on the substrate tube on the unwinding roller can be wound onto the substrate tube on the winding tube by passing through the through hole; one side of the frame seat 1 is provided with two left and right opposing baffles 12 slidingly arranged, the baffles 12 are made of transparent material, and closing the baffles 12 can improve safety.

[0029] It also includes support rollers 28. The vertical plate 11 has a plurality of through holes in the vertical position suitable for the substrate to pass through. In the present embodiment, the number of the through holes is the same as the number of the upper active rollers 23, which are three in total and correspond one to one. When the range surrounded by the substrate is reduced, the substrate passes through the corresponding through holes. A plurality of support rollers 28 suitable for supporting the substrate passing through the through holes on the vertical plate 11 are arranged between the unwinding shaft 21 and the winding shaft 25. The support rollers 28 are used to assist in the transportation of the substrate.

[0030] It also includes a driving motor 54 installed on the rear side of the lower part of the frame seat 1, and a connecting rod 51 rotates between the eccentric ends of multiple active rollers 23 in the same group of active rollers 23, so that the rotation of one active roller 23 can drive the other active rollers 23 in the same group to rotate synchronously through the connecting rod 51, and a connecting rod 51 also rotates between the eccentric ends of multiple active rollers 27 in the same group of active rollers 27, so that the rotation of one active roller 27 can drive the other active rollers 27 in the same group to rotate synchronously through the connecting rod 51, one of the active rollers 23 in the same group of active rollers 23 and one of the active rollers 27 in the same group of active rollers 27 are connected to a synchronous pulley 52, and a synchronous belt 53 is transmitted between the four synchronous pulleys 52, and the inner ring and outer ring of the synchronous belt 53 are connected to the inner ring and outer ring of the synchronous belt 53. The circles all have teeth, and the output shaft of the driving motor 54 is connected to a synchronous pulley 2 55 which is pressed upward on the lower side of the synchronous belt 53 in an outer tensioning manner. The synchronous pulley 2 55 at this position ensures the effective meshing teeth number of the synchronous belt 53 and the two synchronous pulleys 1 52 below. The driving motor 54 is controlled to make the synchronous pulley 2 55 mesh and drive the synchronous belt 53 to drive the four synchronous pulleys 1 52 to rotate, thereby synchronously driving all the active rollers 1 23 and all the active rollers 2 27 to rotate in the same direction to actively convey the substrate, and the upper rear side of the frame seat 1 rotates to have a synchronous pulley 3 which is pressed downward on the upper side of the synchronous belt 53 in an outer tensioning manner. The synchronous pulley 3 at this position ensures the effective meshing teeth number of the synchronous belt 53 and the two synchronous pulleys 1 52 above, and the rotation of the synchronous belt 53 will drive the synchronous pulley 3 to rotate passively.

[0031] It also includes a linear drive group arranged on the frame seat 1, and the driven roller 22, the driven roller 26 and the limiting roller 24 all slide through the frame seat 1. The height of the driven roller 22 is adjusted to change the distance between it and the active roller 23, thereby changing the force and position when the substrate is stretched open to improve adaptability. The driven roller 22 and the driven roller 26 are driven by the linear drive group to slide along the frame seat 1. A connecting plate 29 rotates between the limiting roller 24 and the driven roller 22 closest to the unwinding shaft 21. When the driven roller 22 closest to the unwinding shaft 21 is raised or lowered, the limiting roller 24 will be driven to rise or fall synchronously through the connecting plate 29. At this time, the control cylinder 35 drives the coating die 34 to maintain contact with the substrate, thereby ensuring the normal progress of the coating operation.

[0032] The linear drive group includes a slide column 61 sliding through the frame seat 1 and a cylinder 2 62 installed on the frame seat 1. The slide column 61 is rotated on the driven roller 1 22, the driven roller 26 and the limiting roller 24. The slide column 61 on the driven roller 1 22 and the slide column 61 on the driven roller 2 26 are respectively connected to the telescopic rods of different cylinders 2 62. The slide column 61 is driven by the cylinder to move up and down to adjust the height of the driven roller 1 22 and the driven roller 2 26.

[0033] In summary, in the technical solution part of the coating device that mainly solves the problems of the prior art, the unwinding shaft 21 rotates counterclockwise to drive the substrate tube thereon to unwind the wound substrate, and the winding shaft 25 rotates counterclockwise to drive the substrate tube thereon to wind up the substrate unwinded by the substrate tube on the unwinding shaft 21; during unwinding, the multiple driven rollers 22 and the multiple active rollers 23 make the substrate extend in a square spiral away from the unwinding shaft 21, at which time only the inner side of the substrate is supported by contact, and the coating die head 34 can apply material to the outer side of the substrate, so that the material on the outer side of the substrate is not damaged by friction; during winding, the multiple driven rollers 26 and the multiple active rollers 27 make the substrate extend in a square spiral close to the winding shaft 25, at which time only the inner side of the substrate is supported by contact, and the material on the outer side of the substrate is still not affected by friction; at the same time, since the spiral substrate has multiple layers stacked together, the energy of the light curing lamp group 4 can pass through the substrate to simultaneously illuminate and cure the multiple layers of the substrate, thereby improving the utilization rate and curing efficiency.
