Description

Technical Field

[0001] The utility model relates to the technical field of holographic paper processing, in particular to a surface coating device for holographic paper. Background Art

[0002] Holographic paper is a kind of paper with holographic patterns or images on its surface. A very thin layer of metal foil is pressed on the outer surface of the holographic paper, which can reflect a variety of colors in light. It is precisely because of this characteristic that holographic paper is widely used in high-end gift boxes, cosmetic boxes, tobacco and alcohol boxes, etc. to increase beauty and attract customers to buy.

[0003] During the processing of holographic paper, it is necessary to coat the holographic paper to obtain better effect. Therefore, the holographic paper will be placed on the coating equipment for coating during processing. In order to improve the use effect of the holographic paper, both sides of the holographic paper will be coated to meet the use needs. However, during the coating process, the staff coats one side of the holographic paper. After the coating is completed, the position of the holographic paper is adjusted, and it is turned over and the other side of the holographic paper is processed. Since the surface just coated with the paint is relatively wet, it cannot be turned over immediately for processing, so it needs to be dried before operation. Such operation undoubtedly increases the work flow and reduces work efficiency. Therefore, a holographic paper surface coating device is proposed to solve the above problems. Utility Model Content

[0030] Example

[0031] Reference Figure 1-Figure 6 The utility model provides a technical solution: a holographic paper surface coating device includes a bottom plate 1 and a coating mechanism 3, and a vertical plate 2 is fixedly installed on the upper surface of the bottom plate 1, the coating mechanism 3 includes a hollow bin 31, the hollow bin 31 is fixedly installed on one side of the vertical plate 2, a collecting bin 311 is arranged inside the hollow bin 31, a discharge hole 312 is opened at the bottom of the collecting bin 311, a material baffle plate 313 is slidably connected inside the hollow bin 31, a rotating roller 32 is rotatably installed on one side of the vertical plate 2, a circular plate 321 is fixedly installed on the outer surface of the rotating roller 32, a pushing block 322 is fixedly installed outside the circular plate 321, and a flip roller 33 is rotatably installed on one side of the vertical plate 2.

[0032] In a preferred embodiment, a through hole 4 is provided on the upper surface of the baffle plate 313, a circular hole 5 is provided on the bottom of the hollow bin 31, and a side surface of the baffle plate 313 is fixedly connected to a connecting rod 6, which passes through the interior of the hollow bin 31 and is slidably connected inside the hollow bin 31. In order to facilitate the falling of the paint onto the coating roller 7, a circular hole 5 is provided at the bottom of the hollow bin 31, so that the raw materials inside the collection bin 311 can fall from the inside of the hollow bin 31 to the coating roller 7. In order to save paint, a slidable baffle plate 313 is installed inside the hollow bin 31 of the device. When the baffle plate 313 moves inside the hollow bin 31, the collection bin 311 cannot fall from the hollow bin 31, thereby achieving the purpose of saving paint.

[0033] In a preferred embodiment, one side of the vertical plate 2 is rotatably connected to the coating roller 7, and one side of the coating roller 7 is fixedly connected to the transmission shaft. A driving motor 8 is fixedly installed on the outside of the vertical plate 2, and the output end of the driving motor 8 is fixedly connected to the transmission shaft. To facilitate coating of the outer surface of the product, a driving motor 8 is installed on the vertical plate 2. The driving motor 8 drives the coating roller 7 to rotate, so that the coating roller 7 continuously rolls on the outer surface of the product, thereby coating the outer surface of the product and meeting the processing requirements.

[0034] In a preferred embodiment, a control motor 9 is fixedly installed on the outer surface of the vertical plate 2, a rotating shaft is fixedly installed on the output end of the control motor 9, and a collecting roller 10 is installed on the outer surface of the rotating shaft. After the product is coated, in order to avoid scattering, the control motor 9 is fixedly installed on the vertical plate 2. By driving the collecting roller 10 to rotate by the control motor 9, the product can be rolled up.

[0035] The device can coat the two outer surfaces of the product, so two rotating rollers 32 are set, and the two rotating rollers 32 are connected by belt transmission. One of the rotating rollers 32 is also connected to the coating roller 7 by belt transmission. By setting two rotating rollers 32, two hollow bins 31 are also installed at the same time. The same structure is installed inside the hollow bins 31, so that the paint can be discharged through the two hollow bins 31 and the two outer surfaces of the product can be coated for use.

[0036] The device applies paint on the outer surface of the product. Since the newly applied paint is relatively wet, it is easy to get smudged during the subsequent movement. To solve this problem, a drying mechanism 11 is installed on the outside of the vertical plate 2. The drying mechanism 11 includes a heating roller 111, an electric heating plate 112 and an exhaust fan 113. The heating roller 111 is rotatably installed on the outer surface of the vertical plate 2. A processing chamber 12 is also fixedly installed on the outer surface of the vertical plate 2. The electric heating plate 112 is fixedly installed inside the processing chamber 12. An air outlet 13 is provided on the outer surface of the processing chamber 12. An exhaust fan 113 is fixedly installed on the outer surface of the processing chamber 12. The exhaust fan 113 is arranged on the outer surface of the processing chamber 12. The exhaust fan 113 is arranged on the outer surface of the processing chamber 12. The exhaust fan 113 is arranged on the outer side of the electric heating plate 112. The exhaust end of the exhaust fan 113 corresponds to the position of the electric heating plate 112.

[0037] In actual use, in order to make the paint dry quickly, the coated surface will be dried after coating. The product moves from the upper surface of the heating roller 111, and the product is heated by the heating roller 111 to achieve the effect of drying the paint. To improve the drying effect of the paint, when the product passes the turning position, the device draws external air through the exhaust fan 113 to blow the electric heating plate 112. The electric heating plate 112 generates heat by itself, which can be blown onto the outer surface of the product together with the wind. The wind blown out from the inside of the processing chamber 12 will be hot air, which can accelerate the drying of the paint.

[0038] Specifically, the working process or working principle of the holographic paper surface coating device is as follows: during the processing of the holographic paper, it is necessary to coat the holographic paper in order to obtain better effects, so the holographic paper will be placed on the coating equipment for coating during processing, and in order to improve the use effect of the holographic paper, both sides of the holographic paper will be coated to meet the use requirements. However, during the coating process, the staff coats one side of the holographic paper, and after the coating is completed, the position of the holographic paper is adjusted, and it is turned over and then the other side of the holographic paper is processed. Since the side that has just been coated with the paint is relatively moist and cannot be turned over immediately for processing, it needs to be dried before operation. Such operation undoubtedly increases the work flow and reduces work efficiency, so the present device is designed to solve this problem.

[0039] This device can be used to coat both sides of the product in one process, saving time and improving work efficiency. The specific operation is to connect an external power supply, perform preparation work in advance, add the coating material to the interior of the collecting bin 311, and then turn on the drive motor 8. The coating roller 7 is driven by the drive motor 8 to rotate. The coating material inside the collecting bin 311 will fall from the interior of the collecting bin 311 and fall onto the coating roller 7. The coating roller 7 is rotated so that the coating material falls on the outer surface of the coating roller 7.

[0040] The product is then passed through the bottom position of the coating roller 7 and through the bottom of the rotating roller 32. When the product passes through the bottom of the coating roller 7, its surface will be coated by the coating roller 7. When it passes through the position of the rotating roller 32, it will be limited by the rotating roller 32. At this time, the coating of one side of the product can be completed. The product continues to move. When the product passes the position of the flip roller 33, the originally coated surface will face down and the uncoated surface will face up so that the product can continue to be coated. When the product passes through the hollow bin 31 at the bottom end of the vertical plate 2, the material will be discharged from the hollow bin 31 and fall onto the uncoated surface of the product, thereby completing the coating of the product, thereby achieving coating of both sides of the product in one process.

[0041] In order to save the amount of paint, in actual operation, the coating roller 7 is driven to rotate by the driving motor 8, and the rotating roller 32 is also driven to rotate. When the rotating roller 32 rotates, the pushing block 322 is also driven to rotate. When the pushing block 322 rotates to the position of the connecting rod 6, the connecting rod 6 is pushed to move, thereby controlling the movement of the baffle plate 313 inside the hollow bin 31. The through hole 4 on the baffle plate 313 is staggered with the discharge hole 312 on the bottom of the collecting bin 311. At this time, the paint inside the collecting bin 311 will not be discharged, thereby achieving the purpose of saving paint. When the pushing block 322 is moved away from the position of the connecting rod 6, the connecting rod 6 will return to its initial position under the action of the spring, so that the connecting rod 6 can be pushed again later to stagger the baffle plate 313 with the bottom of the collecting bin 311, thereby achieving the purpose of saving paint.

[0042] The same method is also used for the rotating roller 32 at the bottom end of one side of the vertical plate 2 to control the material discharge amount of the hollow bin 31, so as to achieve the purpose of saving paint.

[0043] After coating the surface of the product, in order to make the coating dry quickly, the coated surface will be dried after coating. The product moves from the upper surface of the heating roller 111, and the product is heated by the heating roller 111 to achieve the effect of drying the coating. In order to improve the drying effect of the coating, when the product passes the turning position, the device draws external air through the exhaust fan 113 to blow the electric heating plate 112. The electric heating plate 112 generates heat by itself, which can be blown onto the outer surface of the product together with the wind. The wind blown out from the inside of the processing chamber 12 will be hot air, which can accelerate the drying of the coating so that the original coating will not be affected when the product is turned over. When coating the other side of the product, this drying method is also followed to ensure the processing effect of the product and meet the use requirements.

[0044] Finally, the collecting roller 10 is driven by controlling the motor 9 to continuously collect the product.

[0045] It should be noted that the drive motor 8, the vacuum fan 113 and the control motor 9 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
