Description

Technical Field

[0001] The invention relates to the technical field of thermal paper production, in particular to a thermal paper production coating heat treatment quick-drying device. Background Art

[0002] Thermal paper is also known as thermal fax paper, thermal recording paper, and thermal copy paper. It is a processed paper. The production principle of thermal paper is to coat ordinary paper base with microparticle powder. The ingredients are colorless dyes such as phenols or other acidic substances, separated by a film. Under heating conditions, the film melts and the powder mixes to produce a color reaction. The colored writing on the thermal paper is unstable and easy to fade, making the document content difficult to recognize. Therefore, in the process of thermal paper production, the coating of the thermal paper needs to be heat-treated and quickly dried, and corresponding processing equipment is required for this purpose.

[0003] When performing heat treatment and quick drying, existing processing equipment mostly transfers heat to the paper from one side, which will cause uneven heating on both sides of the paper during heat treatment, thereby affecting the quality of the heat treatment. At the same time, when transporting the paper, due to the long distance of transportation, the paper itself is soft and has a heat-sensitive color-changing layer, which makes it inconvenient to fix it. This will make the paper prone to drooping under its own gravity, greatly affecting the efficient transportation and drying work.

The auxiliary racks 31 are rotatably connected to the auxiliary cylinders 32, so that with the help of the auxiliary cylinders 32 that can rotate at the bottom, the paper can be auxiliary supported, so that the conveying work can be completed more stably. An airflow structure is also provided in the working box 2, and the airflow structure includes air cavities 8 arranged on both sides of the working box 2. A plurality of air holes 9 are arranged at equal intervals on the inner wall of the two air cavities 8 on the side close to each other. A connecting port 10 is provided on the side walls of both ends of one of the air cavities 8. The two connecting ports 10 are respectively connected to the two working chambers 3. A heat-conducting block 11 is fixedly connected to the two connecting ports 10, and a heat-conducting mesh plate 12 is fixedly connected between the two heat-conducting blocks 11. The heat-conducting mesh plate 12, the two drying plates 7 and the two heat-conducting blocks 11 are all made of copper material. The copper material has good thermal conductivity and can absorb and transfer heat well to complete the heat treatment work.

[0025] The heat-conducting mesh plate 12 is located in the air cavity 8, and the heat-conducting mesh plate 12 is arranged opposite to the multiple air holes 9. An air pump 13 and an air extraction pump 14 are respectively provided on the outer walls of both ends of the working box 2. The air-inflation end of the air pump 13 passes through the working box 2 and is arranged opposite to the heat-conducting mesh plate 12. The air extraction end of the air extraction pump 14 passes through the working box 2. A delivery pipe 15 is provided at the end of the air extraction pump 14 away from the working box 2. In this way, while completing the exhaust gas extraction, the heated air is used to assist in heating the paper, so that the paper can be heated more evenly, and then the heat treatment and quick-drying work can be better completed. A delivery component and an auxiliary component are provided on the base 1. The delivery component and the auxiliary component are respectively located on both sides of the working box 2. The delivery pipe 15 is provided at the end of the air extraction pump 14 away from the working box 2. The assembly includes two support columns 16 fixedly connected to the base 1, and the two support columns 16 are symmetrically arranged. There are two rotating shafts 17 rotatably connected between the two support columns 16. The two rotating shafts 17 are fixedly connected to conveyor rollers 18. The two conveyor rollers 18 are made of heat-conducting materials. In this way, when clamping the material, the heat of the material can be effectively transferred, thereby accelerating the heat dissipation efficiency of the material. The two conveyor rollers 18 are located between the two support columns 16. A rotating motor 19 is fixedly connected to the side wall of one of the support columns 16 away from the two conveyor rollers 18. The output end of the rotating motor 19 is fixedly connected to one of the rotating shafts 17. The two rotating shafts 17 One end away from the rotating motor 19 is fixedly connected to a transmission gear 20, and the two transmission gears 20 are meshed with each other, so that the dried paper can be pulled, and then the paper can be stably transported. The auxiliary component includes two support frames 21 fixedly connected to the base 1, and the two support frames 21 are symmetrically arranged. An auxiliary roller 22 is provided between the two support frames 21, and an auxiliary motor 23 is fixedly connected to the side wall of one of the support frames 21 away from the auxiliary roller 22. The auxiliary end of the auxiliary motor 23 passes through the support frame 21 and is fixedly connected to the auxiliary roller 22. The auxiliary roller 22 is provided with a rotating port 24 at one end away from the auxiliary motor 23. The rotating port 24 is provided at the rotating port 24. 4 is rotatably connected to a rotating seat 25, a plurality of adsorption holes 26 are provided on the inner wall of the rotating mouth 24, and an adsorption port 27 is provided on one side of the rotating seat 25. One end of the rotating seat 25 away from the auxiliary motor 23 is fixedly connected to another support frame 21, and an adsorption pump 28 is provided on the support frame 21. An adsorption pump 28 is provided on the adsorption pump 28. An adsorption pipe 29 is provided on the adsorption pump 28. One end of the adsorption pipe 29 away from the adsorption pump 28 passes through the support frame 21 and the rotating seat 25. The adsorption pipe 29 and the adsorption port 27 are connected to each other, so that the paper that has not been dried can be adsorbed and pulled, and the conveying component is cooperated to make the paper move stably in the working box 2, and then the conveying work is completed safely and the heat treatment work is completed efficiently.

[0026] During the use of the present invention, the base 1 is first placed stably with the help of the foot 30, and then the device can be turned on to work. When the device is working, hot water enters the working chamber 3 through the water pipe 5 and the water port 4, and then flows out through the water port 4 and the water pipe 5 on the other side. When the hot water passes through the working chamber 3, it will heat the drying plate 7, and then the drying plate 7 can be in a high temperature state. In this way, the two drying plates 7 located on the upper and lower sides can dry and heat the paper from both sides, so that the thermochromic layer of the paper can evenly complete the heat treatment and quick-drying work, which greatly guarantees the production and processing quality of the thermal paper. At the same time, the vacuum pump 14 can perform exhaust work through the corresponding air cavity 8 and air hole 9, so that the harmful waste gas generated during the heat treatment can be extracted. The air is then transported to a designated area for processing through a delivery pipe 15, effectively avoiding atmospheric pollution. At the same time, the air pump 13 can inflate another air cavity 8, and then allow the air to enter the working box 2 through a plurality of air holes 9 as a supplement. In this process, since the heat-conducting block 11 contacts the hot water in the working chambers 3 on both sides, the heat-conducting block 11 can be heated and heat the heat-conducting mesh plate 12. In this way, the air entering this air cavity 8 will be heated by the heat-conducting mesh plate 12 and become high-temperature air. In this way, when these air enters the working box 2 again, they can use their own high-temperature state to assist in heating the paper, so that the paper can be heated more evenly, and then better complete the heat treatment and quick-drying work, further improving the quality of thermal paper production and processing;

[0027] During the paper conveying and moving process, the rotating motor 19 can drive the two conveying rollers 18 to rotate in the same and opposite directions through the rotating shaft 17 and the two meshing transmission gears 20, so that the paper can be pulled to complete the moving and conveying work while maintaining the state of clamping the paper. This part of the paper has completed the drying heat treatment work, and the clamping work of the conveying roller 18 on the paper will not damage the thermochromic layer of the paper. The other side of the paper will contact the auxiliary roller 22 during the conveying process. At this time, the adsorption pump 28 evacuates the adsorption port 27 through the adsorption tube 29, and then passes through the corresponding adsorption hole 26. Air is sucked out so that the paper can be adsorbed on the auxiliary roller 22. However, since it is a one-sided adsorption, it will not interfere with the thermochromic layer of the paper. At the same time, since the auxiliary roller 22 is rotating and the adsorption port 27 is only located on one side of the rotating seat 25, the auxiliary roller 22 can only adsorb the paper in a partial area. In this way, the auxiliary roller 22 can adsorb and pull the paper during its rotation, and then release the paper. In this way, by continuously cooperating with the two conveying rollers 18, the paper can stably complete the conveying and moving work, and then the paper can stably complete the conveying work and heat treatment quick-drying work in the working box 2.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
