Description

Technical Field

[0001] This utility model relates to the field of thermal paper processing technology, specifically a processing device for thermal medium coating products. Background Technology

[0002] Thermal media coating is a coating specifically designed for thermal paper. Its main components include resin, protective agents, and fillers. Sometimes, special additives such as antistatic agents and foaming agents are also added to enhance the coating's performance and function. The main functions of thermal media coating include: protecting the paper by preventing it from getting damp, deformed, and stained, thus extending the lifespan of the thermal paper; enhancing ink stability by preventing the paper surface from absorbing moisture and oxidizing in the air, ensuring the stability and clarity of the printed ink; improving print quality by making the printed ink more vibrant and bright; and improving durability by enhancing the durability of the thermal paper, making it suitable for various printing applications. Thermal paper typically consists of three layers: the bottom layer is the paper base, the second layer is the thermal coating, and the third layer is the protective layer.

[0003] Patent CN221320504U discloses a thermal paper coating machine, including a machine casing with through slots at the center of both sides. A feeding device is installed at the bottom left side of the machine casing via a fixed platform, and a winding device is installed at the bottom right side of the machine casing via a fixed platform. A box body is bolted to the center of the top of the machine casing. The inner cavity of the box body is equipped with a scraper assembly for thermal paper. Through the cooperation of a motor, rotating shaft, gear, rack and pinion, and scraper, the scraper is moved to adjust the distance between the scraper and the thermal paper, thereby adjusting the thickness of the coating scraped off the thermal paper, making the coating distribution more uniform and improving the quality of the thermal paper. Through the cooperation of a pump, feed pipe, and discharge pipe, the coating is sprayed onto the coating roller to coat the thermal paper. Through the cooperation of a heating box, fan, heating wire, and connecting frame, hot air is sprayed onto the thermal paper to dry it.

[0004] The above-mentioned device has certain shortcomings in its use: the device directly coats the thermal paper with a coating roller, and there is no support for the thermal paper to be coated below the coating roller. During the coating process, there will be unstable contact with the coating roller and uneven coating. Although the device is equipped with a scraper to remove the coating from the thermal paper after coating, the excess coating will remain on the scraper. The machine needs to be stopped and cleaned every once in a while, which greatly affects the work efficiency.

[0005] To address these issues, this invention provides a processing apparatus for thermosensitive medium coating products. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a processing device for thermosensitive medium coating products, which solves the aforementioned problems.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a heat-sensitive medium coating product processing device, including a base, a U-shaped frame installed in the middle of the top wall of the base, a coating component installed on the top wall of the U-shaped frame, a leveling component installed on the left side wall of the coating component, a drying component installed on the right side wall of the coating component, a feeding device installed on the left side of the top wall of the base, and a winding device installed on the right side of the top wall of the base;

[0008] The coating assembly includes a high-precision electric actuator, which is fixedly installed on the top wall of a U-shaped frame. The movable end of the high-precision electric actuator slides through the U-shaped frame and is fixedly installed on a U-shaped seat. A coating roller is rotatably installed on the inner wall of the U-shaped seat. A support roller is rotatably installed on the bottom of the inner wall of the U-shaped frame. Limiting grooves are provided on both the front and rear walls of the U-shaped frame. Limiting sliders are slidably installed on the inner walls of the limiting grooves. Distance sensors are installed on the bottom walls of both limiting sliders.

[0009] The drying assembly includes a hot and cold air blower, which is fixedly installed on the rear of the top wall of the U-shaped frame. An L-shaped seat is fixedly installed on the right side wall of the U-shaped seat. A limiting seat is fixedly installed at the bottom of the L-shaped seat. An air outlet pipe is installed on the inner wall of the limiting seat. Several air outlet hoods are evenly connected to the bottom of the outer wall of the air outlet pipe. The air outlet of the hot and cold air blower is connected to a movable pipe.

[0010] Through the above technical solution, the setting of the coating component can adjust the distance between the coating roller and the support roller according to the thickness of the thermal paper to be processed, so that the coating process is more uniform in the subsequent coating process. The setting of the drying component can dry the coated thermal paper and then roll it up directly.

[0011] Furthermore, the outer walls of both limiting sliders are fixedly connected to the outer wall of the U-shaped seat, the coating roller is connected to the external feeding equipment, and the left side wall of the U-shaped seat is fixedly connected to the leveling assembly.

[0012] With the above technical solution, when the U-shaped seat is moving up and down, it will drive the limit slider to slide along the inner wall of the corresponding limit groove to prevent positional deviation.

[0013] Furthermore, the air inlet of the hot and cold air blower is connected to the outside, the bottom end of the movable pipe is connected to the outer wall of the air outlet pipe, and a transmission roller is installed on the right side of the top wall of the base and below the air outlet pipe.

[0014] Through the above technical solution, the first transmission roller mainly serves to support and transport the coated thermal paper.

[0015] Furthermore, the leveling component includes a connecting plate, which is fixedly connected to the left side wall of the U-shaped seat, and a receiving frame is fixedly installed on the bottom wall of the connecting plate.

[0016] Through the above technical solution, the U-shaped seat will drive the connecting plate to move when it moves up and down.

[0017] Furthermore, a limiting groove is formed in the inner wall of the receiving frame, and several springs are evenly installed in the inner wall of the limiting groove. The bottom end of each spring is fixedly installed with the same limiting plate. The outer wall of the limiting plate is slidably connected to the inner wall of the limiting groove. A connecting block is fixedly installed on the bottom wall of the limiting plate, and a U-shaped frame is fixedly installed on the bottom wall of the connecting block. A leveling roller is rotatably installed on the inner wall of the U-shaped frame.

[0018] The above technical solution allows the leveling roller to level the thermal paper to be coated, preventing bending or curling edges from affecting subsequent coating processes.

[0019] Furthermore, a second transmission roller is installed on the left side of the top wall of the base and below the leveling roller.

[0020] Through the above technical solution, the second transmission roller can mainly provide support and conveying for the thermal paper to be processed.

[0021] Furthermore, a support frame is fixedly installed on the bottom wall of the base.

[0022] Through the above technical solution, the support frame provides support and fixation for the entire device.

[0023] Beneficial effects

[0024] This invention provides a processing apparatus for thermosensitive medium coating products. Compared with the prior art, it has the following advantages:

[0025] (1) The thermal medium coating product processing device pushes the U-shaped seat and coating roller downward through a high-precision electric push rod. The U-shaped seat drives the limiting slider to move downward along the limiting groove, and drives the distance sensor to measure the distance between the limiting groove and the bottom wall of the limiting groove. The external feeding equipment uniformly feeds the coating to the outer wall of the coating roller. The coating roller coats the surface of the thermal paper. When the U-shaped seat descends, it will drive the L-shaped seat and the limiting seat to descend. The limiting seat drives the air outlet pipe and the air outlet hood to descend. The hot and cold air blown out by the hot and cold air blown out enters the air outlet pipe through the movable pipe and blows out from the air outlet hood to dry the thermal paper coated on the outer wall of the transmission roller. It is then wound up by the winding equipment, so that when coating the thermal paper, it can be precisely adjusted and adapted according to the paper of different thicknesses. After the coating is completed, it will continue to dry and then be directly wound up. During the processing, it supports the thermal paper, making the coating more uniform, and there is no need to use a scraper to remove it.

[0026] (2) The thermal medium coating product processing device uses a U-shaped seat to drive the connecting plate and the receiving frame to descend. The receiving frame drives the limiting plate, connecting block, U-shaped frame and leveling roller to descend, so that the leveling roller abuts against the top wall of the thermal paper and the two transmission rollers. The leveling roller pushes the U-shaped frame in the opposite direction to drive the connecting block and the limiting plate to slide and compress the spring in the inner wall of the limiting groove. The spring pushes the leveling roller to apply pressure, so that the leveling roller can level the thermal paper to be processed that passes through the top wall of the two transmission rollers. This leveling roller will level the thermal paper before coating processing, preventing the occurrence of curling and wrinkles that will affect the subsequent coating processing. The setting of the leveling roller can improve the quality of subsequent product processing. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example 1:

[0035] Please see Figure 1-5 A heat-sensitive medium coating product processing device includes a base 8, a U-shaped frame 7 installed in the middle of the top wall of the base 8, a coating component 4 installed on the top wall of the U-shaped frame 7, a leveling component 5 installed on the left side wall of the coating component 4, a drying component 6 installed on the right side wall of the coating component 4, a feeding device 2 installed on the left side of the top wall of the base 8, and a winding device 3 installed on the right side of the top wall of the base 8.

[0036] The coating assembly 4 includes a high-precision electric actuator 41, which is fixedly installed on the top wall of the U-shaped frame 7. The movable end of the high-precision electric actuator 41 slides through the U-shaped frame 7 and is fixedly installed on a U-shaped seat 45. A coating roller 46 is also rotatably installed on the inner wall of the U-shaped seat 45. A support roller 47 is rotatably installed on the bottom of the inner wall of the U-shaped frame 7.

[0037] The drying assembly 6 includes a hot and cold air blower 62, which is fixedly installed on the rear of the top wall of the U-shaped frame 7. An L-shaped seat 64 is fixedly installed on the right side wall of the U-shaped seat 45. A limiting seat 65 is fixedly installed at the bottom of the L-shaped seat 64. An air outlet pipe 66 is installed on the inner wall of the limiting seat 65. Several air outlet hoods 67 are evenly connected to the bottom of the outer wall of the air outlet pipe 66. The air outlet of the hot and cold air blower 62 is connected to a movable pipe 63. The outer walls of the two limiting sliders 43 are fixedly connected to the outer wall of the U-shaped seat 45. The coating roller 46 is connected to the external feeding equipment. The left side wall of the U-shaped seat 45 is fixedly connected to the leveling assembly 5.

A transfer roller 61 is installed on the right side of the top wall of the base 8 and below the air outlet pipe 66.

[0038] In this embodiment of the utility model, the purpose of this arrangement is that the coating component 4 can adjust the distance between the support roller 47 and the coating roller 46 according to the different thicknesses of the thermal paper, and the support roller 47 provides support for the thermal paper. The coating roller 46 distributes the coating more evenly during the coating process, which expands the adaptability and effectiveness of the entire device. After the thermal paper is coated, the drying component 6 can dry the thermal paper that has passed through the transfer roller 61, and then it can be directly rolled up, which expands the functionality of the entire device.

[0039] Example 2:

[0040] Please see Figure 1-5This embodiment provides a technical solution based on embodiment one: the leveling component 5 includes a connecting plate 51, which is fixedly connected to the left side wall of the U-shaped seat 45. A receiving frame 52 is fixedly installed on the bottom wall of the connecting plate 51. A limiting groove 59 is opened in the inner wall of the receiving frame 52. A plurality of springs 53 are evenly installed in the inner wall of the limiting groove 59. The bottom end of the plurality of springs 53 is fixedly installed with the same limiting plate 54. The outer wall of the limiting plate 54 is slidably connected to the inner wall of the limiting groove 59. A connecting block 55 is fixedly installed on the bottom wall of the limiting plate 54.

A second transmission roller 58 is installed on the left side of the top wall of the base 8 and below the leveling roller 57. A support frame 1 is fixedly installed on the bottom wall of the base 8.

[0041] In this embodiment of the utility model, the purpose of this arrangement is that, before coating the thermal paper, the leveling component 5, through the cooperation of the leveling roller 57 and the transfer roller 58, can level any wrinkles or bends that may exist on the surface of the thermal paper, preventing these parts from entering the coating roller 46 for direct coating and affecting the coating quality of the thermal paper. The pretreatment by the leveling component 5 can improve the production quality of the thermal paper.

[0042] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0043] During operation, the feeding device 2, winding device 3, high-precision electric actuator 41, distance sensor 44, and hot / cold air blower 62 are first connected via an external power supply and controller. The thermal paper from the feeding device 2 is fed through transfer roller 2 58, support roller 47, and transfer roller 1 61 and then connected to the winding device 3. When the coating process on the outer surface of the thermal paper begins, the distance between the coating roller 46 and the support roller 47 is adjusted according to the thickness of the thermal paper. The high-precision electric actuator 41 pushes the U-shaped seat 45 and the coating roller 46 downwards, causing the U-shaped seat 45 to move downwards. The corresponding limit slider 43 moves downward along the inner wall of the corresponding limit groove 42. When the limit slider 43 moves downward, the distance sensor 44 measures the distance between the limit slider 43 and the bottom wall of the limit groove 42. The highest point of the outer wall of the support roller 47 is at the same height as the bottom wall of the limit groove 42. The descent height is then monitored in real time by an external controller. When the set height is reached, the high-precision electric push rod 41 stops working and maintains its position. The coating is then uniformly fed to the outer wall of the coating roller 46 by an external feeding device. The coating roller 46 coats the surface of the thermal paper. During processing, when the U-shaped seat 45 descends to its lowering height, it drives the connecting plate 51 and the receiving frame 52 to descend. When the receiving frame 52 descends, it drives the limiting plate 54, connecting block 55, U-shaped frame 56, and leveling roller 57 to descend, ultimately causing the leveling roller 57 to abut against the top wall of the thermal paper and the second transfer roller 58. The leveling roller 57 pushes the U-shaped frame 56 in the opposite direction, causing the connecting block 55 and the limiting plate 54 to slide and compress the spring 53 in the inner wall of the limiting groove 59. Under the elastic action of the spring 53, the leveling roller 57 is pushed to apply pressure, so that the paper... The flat roller 57 can flatten the thermal paper to be processed passing over the top wall of the second transmission roller 58, preventing wrinkles and bending from affecting the coating processing effect. At the same time, when the U-shaped seat 45 descends, it will simultaneously drive the L-shaped seat 64 and the limit seat 65 to descend. The limit seat 65 drives the air outlet pipe 66 and the air outlet hood 67 to descend. The hot and cold air fan 62 is started to blow out hot air through the movable pipe 63 into the air outlet pipe 66 and blown out from the air outlet hood 67 to dry the thermal paper coated on the outer wall of the first transmission roller 61. Then it is wound up by the winding device 3.
