Description

Technical Field

[0001] This utility model relates to a horizontal control air blowing device for a paper calender, and in particular to a horizontal control air blowing device for a paper calender, belonging to the field of papermaking technology. Background Technology

[0002] Calenders can control the uniformity of the paper web's thickness, resulting in smoother paper. However, in actual production, due to the condition of the paper web, localized grooves can easily appear after the calender. Production staff often resort to localized air cooling of the calender to induce slight deformation and compensate for these web differences, thus resolving the groove problem. While this method improves the localized groove issue, it has two main drawbacks: First, the grooves are not fixed in location. To achieve full coverage across the paper web, a large number of air blowers are needed for the calender's web width, requiring constant adjustment as the groove position changes. This adjustment process often necessitates repeated movement and fixing of the air blowers, making it very tedious. Second, the calender's air blowers use the workshop's process air. The use of these blowers often leads to a loss of compressed air in the workshop. Excessive use of blowers can severely affect the stability of the compressed air supply. In situations requiring large amounts of compressed air, such as paper breaks, a sudden drop in compressed air can easily cause misalignment of spare parts.

[0003] Therefore, it is urgent to improve the air blowing device for the horizontal control of the paper calender in order to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a horizontal control air blowing device for a paper calender. Compared with traditional multiple messy air blowing pipes, it is more convenient and quick to adjust. At the same time, it can reduce the compressed air pressure, reduce the air consumption, prevent the high load of the workshop air compressor system from affecting the stability of the compressed air in the workshop, and prevent the occurrence of spare parts deviation accidents due to the instantaneous drop in compressed air.

[0005] To achieve the above objectives, the main technical solution adopted by this utility model includes: a horizontal control air blowing device for a paper calender, comprising a main air supply pipe, a plurality of air blowing mechanisms connected to the main air supply pipe, the main air supply pipe being fixed by a plurality of fixing mechanisms, the air blowing mechanism comprising a stainless steel pipe, a branch pipe switch ball valve, an adjustable pressure reducing valve, a universal adjusting metal air pipe and an air blowing head connected in sequence, the air blowing head having a rotatably connected air direction adjusting plate inside, and the fixing mechanism comprising a base, a pressure plate slidably connected to the base and an elastic pressure plate disposed on the pressure plate.

[0006] Preferably, both the branch switch ball valve and the adjustable pressure reducing valve are stainless steel valves, and the universal adjusting metal air pipe is a bamboo-joint type universal adjusting metal air pipe.

Detailed Implementation

[0021] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0022] like Figures 1-5 As shown, the paper calender horizontal control air blowing device provided in this embodiment includes a main air supply pipe 1, with several air blowing mechanisms 2 connected to the main air supply pipe 1. The main air supply pipe 1 is fixed by several fixing mechanisms 3. The air blowing mechanism 2 includes a stainless steel pipe 201, a branch pipe switch ball valve 202, an adjustable pressure reducing valve 203, a universal adjustable metal air pipe 204, and an air blowing head 205 connected in sequence. The adjustable pressure reducing valve 203 can adjust the gas pressure, reduce the compressed air pressure, reduce air consumption, prevent the high load of the workshop air compressor system from affecting the stability of the workshop compressed air, and prevent the occurrence of spare parts deviation accidents due to the instantaneous drop in compressed air. The universal adjustable metal air pipe 204 can be used for convenient and quick adjustment.

[0023] Furthermore, both the branch pipe switch ball valve 202 and the adjustable pressure reducing valve 203 are stainless steel valves. The stainless steel material can greatly improve the service life of the valves and will not easily rust. The universal adjustment metal air pipe 204 is a bamboo joint universal adjustment metal air pipe, which is convenient for fixing after universal adjustment. The air blowing head 205 is a flat mouthpiece air blowing head. The flat mouthpiece air blowing head can further reduce the air volume while improving the control accuracy.

[0024] An air direction adjustment plate 4 is rotatably connected inside the air blowing head 205. A rotating rod 5 is provided on the upper end surface of the air direction adjustment plate 4, which extends through to the surface of the air blowing head 205. A fixing plate 6 is provided on the upper end surface of the rotating rod 5, and the fixing plate 6 is fixed by a fixing pin 7.

[0025] The upper surface of the air blowing head 205 has several positioning magnetic holes 8 arranged around the rotating rod 5. The fixing pin 7 is slidably connected to the fixing plate 6. The fixing pin 7 is a magnetic pin that is magnetically connected to the positioning magnetic holes 8. When it is necessary to adjust the air direction adjustment plate 4, the fixing pin 7 is taken out from the positioning magnetic holes 8. Then, the fixing plate 6 is rotated, which drives the rotating rod 5 to rotate, thereby driving the air direction adjustment plate 4 to rotate and adjust to the required position. Then, the fixing pin 7 is inserted into the corresponding positioning magnetic holes 8 to fix it. The air direction adjustment plate 4 extends to the outside of the air blowing head 205 to facilitate the adjustment of the air direction.

[0026] The fixing mechanism 3 includes a base 301, a pressure plate 302 slidably connected to the base 301, and an elastic pressure plate 101 disposed on the pressure plate 302; the upper end face of the base 301 is provided with a lower semi-circular groove 9 that is connected to the main gas pipeline 1, and T-shaped sliding grooves 10 are provided on both sides of the upper end face of the base 301; the lower end face of the pressure plate 302 is provided with an upper semi-circular groove 11, and T-shaped sliders 12 that are slidably connected to the T-shaped sliding grooves 10 are provided on both sides of the lower end face of the pressure plate 302.

[0027] Furthermore, a sleeve 13 is provided on the upper end face of the pressure plate 302, and a compression spring 14 is provided on the upper part of the sleeve 13. A slide rod 15 is connected to the compression spring 14. The upper end face of the elastic pressure plate 101 is connected to the slide rod 15. The slide rod 15 and the compression spring 14 make the elastic pressure plate 101 elastic, which facilitates the later fixing of the main gas pipeline 1 and the later disassembly of the pressure plate 302. When fixing the main gas pipeline 1, the main gas pipeline 1 is placed in the lower semi-circular groove 9 of the base 301. Inside, press the main pressure plate 302, and use the elastic pressure plate 101 to contact the upper end face of the main gas pipeline 1. The compression spring 14 is used to make the elastic pressure plate 101 move upward. Then, the T-shaped slider 12 can be directly slidably connected to the T-shaped slide groove 10. When disassembling later, the pressure plate 302 can be directly slidably separated from the base 301. Pull plates 16 are provided on both sides of the pressure plate 302. The pull plates 16 are provided to facilitate the sliding of the pressure plate 302 and realize quick separation from the base 301.
