Description

Technical Field

[0001] This utility model relates to the field of papermaking technology, specifically to a clean papermaking steam circulation device. Background Technology

[0002] The clean papermaking steam circulation device is used to process paper using steam. Papermaking can be done by machine or by hand. Machine papermaking is carried out continuously on a papermaking machine. Pulp suitable for paper quality is diluted with water to a certain concentration, and then initially dewatered on the wire section of the papermaking machine to form a wet sheet. After pressing and dewatering, it is then dried into paper.

[0003] Chinese Patent Publication No. CN215104269U discloses a clean papermaking steam circulation device, including a main frame, a water tank, a third pipe, a suction pump, and a steam engine. A roller is installed inside the main frame, and bearings are fixed at both ends of the roller. A first pipe runs through the roller and bearings, and nozzles are distributed on the first pipe. A valve is located on the left side of the roller, and a second pipe is located to the left of the valve. A perforated plate is installed at the top of the second pipe. A third pipe is installed below the water tank, and a suction pump is located in the middle of the third pipe. The end of the third pipe is fixed... The device includes a steam engine; this clean papermaking steam circulation device is equipped with an electric actuator, a second pipe, a water collector, and a valve. The electric actuator can drive the water collector to move, causing the second pipe on the water collector to retract inward and penetrate into the valve, thus recycling the condensate in the rollers for reuse. This method can reduce environmental damage. However, the distance between the two rollers in the above patent cannot be adjusted, and the rollers cannot be tightly fitted to the paper during drying, resulting in poor paper drying effect and reducing the practicality of the device. Therefore, we propose a clean papermaking steam circulation device. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clean papermaking steam circulation device, comprising a workbench, a steam assembly, a mounting frame, an adjusting mechanism, a first fixing frame, a second fixing frame, and an installation pipe. The steam assembly is fixed to the bottom of the workbench, the mounting frame is fixed to the top of the workbench, the adjusting mechanism is disposed inside the mounting frame, the first fixing frame is fixed to the top of the workbench, the second fixing frame is fixed to the bottom of the adjusting mechanism, and an installation pipe is fixedly inserted through the inner sides of the first fixing frame and the second fixing frame. A drying element is rotatably mounted on the outer side of the installation pipe. The dry roller has a rotating mechanism on one side of the first and second fixed frames. The inside of the mounting tube is connected to a spray pipe through the rotating mechanism. Spray nozzles are uniformly fixed on the outside of the spray pipe. The adjusting mechanism includes a bidirectional screw that rotates through the top between the two sides inside the mounting frame. Turntables are fixed at both ends of the bidirectional screw. A movable seat is symmetrically screwed to the outside of the bidirectional screw. A connecting rod rotates inside the movable seat. Sliding rods are fixed at the four corners of the top of the second fixed frame. Connecting seats are symmetrically fixed at the top of the second fixed frame. A limit rod is fixed between the two sides inside the mounting frame.

[0007] One end of the connecting rod rotates inside the connecting seat, and the movable seat slides outside the limiting rod.

[0008] As a further description of the above technical solution:

[0009] The slide rod slides through the top of the mounting bracket, and a baffle is fixed to the top of the slide rod.

[0010] As a further description of the above technical solution:

[0011] The rotating mechanism includes a drive motor fixed to one side of the first fixed frame and the second fixed frame. A drive gear is fixed to the end of the output shaft of the drive motor. A rotating tube is rotatably connected to one end of the mounting tube via a bearing. A driven gear is fixed to the outside of the rotating tube.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This clean papermaking steam circulation device rotates a turntable, which drives a bidirectional screw to rotate. This causes the moving seats to move away from each other outside the limit rod, thereby driving the connecting rod to deflect vertically, causing the connecting seat to descend, which in turn causes the second fixed frame to descend. This brings the two drying rollers closer together, allowing the two sides of the paper to adhere to the surface of the drying rollers, improving the drying effect of the paper and enhancing the practicality of the device.

[0018] 2. This clean papermaking steam circulation device, by starting the drive motor, drives the active gear to rotate, which in turn drives the driven gear to rotate, causing the rotating pipe to rotate, which in turn drives the nozzle to rotate, thus making the nozzle rotate. This allows the steam to heat the inner wall of the installation pipe evenly, avoiding dead corners, improving the heating effect, preventing uneven drying of the paper, and further improving the drying effect.

[0027] This invention provides a clean papermaking steam circulation device that ensures the two sides of the paper adhere to the surface of the drying roller, improving the drying effect and enhancing the practicality of the device. Please refer to [link / reference needed]. Figure 1-4 It includes a workbench 100, a steam assembly 200, a mounting bracket 300, an adjustment mechanism 400, a first fixing bracket 500, a second fixing bracket 600, and a mounting pipe 700;

[0028] Please refer to it again. Figure 1 The workbench 100 is used to install the steam assembly 200, the mounting bracket 300, the adjustment mechanism 400, the first fixing bracket 500, the second fixing bracket 600, and the mounting pipe 700;

[0029] Please refer to it again. Figure 1The steam assembly 200 is fixed to the bottom of the workbench 100, the mounting bracket 300 is fixed to the top of the workbench 100, the adjustment mechanism 400 is disposed inside the mounting bracket 300, the first fixing bracket 500 is fixed to the top of the workbench 100, and the second fixing bracket 600 is fixed to the bottom of the adjustment mechanism 400.

[0030] Please refer to it again. Figure 1 An installation tube 700 is fixed through the inner side of the first fixed frame 500 and the second fixed frame 600, and a drying roller 710 is rotated on the outer side of the installation tube 700. A rotating mechanism 800 is provided on one side of the first fixed frame 500 and the second fixed frame 600.

[0031] Please refer to it again. Figure 2 The inside of the mounting tube 700 is connected to the nozzle 720 through the rotating mechanism 800. The nozzle 730 is evenly fixed on the outside of the nozzle 720. The adjusting mechanism 400 includes a bidirectional screw 410 that passes through and rotates between the top of the two sides inside the mounting frame 300. Turntables 411 are fixed at both ends of the bidirectional screw 410.

[0032] Please refer to it again. Figure 2 A movable seat 420 is symmetrically screwed to the outer side of the bidirectional screw 410. A connecting rod 430 rotates inside the movable seat 420. Slide rods 440 are fixed at the four corners of the top of the second fixed frame 600. Connecting seats 450 are symmetrically fixed to the top of the second fixed frame 600. A limit rod 460 is fixed between the two sides inside the mounting frame 300.

[0033] In summary, by rotating the turntable 411, the bidirectional screw 410 is driven to rotate, causing the movable seat 420 to move away from each other outside the limit rod 460. This causes the connecting rod 430 to deflect in the vertical direction, which in turn causes the connecting seat 450 to descend, thereby causing the second fixed frame 600 to descend. This brings the two drying rollers 710 closer together, allowing the two sides of the paper to adhere to the surface of the drying rollers 710, thus improving the drying effect of the paper and enhancing the practicality of the device.

[0034] Please refer to it again. Figure 2 One end of the connecting rod 430 rotates inside the connecting seat 450, and the moving seat 420 slides outside the limiting rod 460.

[0035] Please refer to it again. Figure 2 The slide bar 440 slides through the top of the mounting bracket 300, and a baffle is fixed to the top of the slide bar 440.

[0036] Please refer to it again. Figure 3The rotating mechanism 800 includes a drive motor 810 fixed to one side of the first fixed frame 500 and the second fixed frame 600. The output shaft end of the drive motor 810 is fixed with a drive gear 820. One end of the mounting tube 700 is rotatably connected to a rotating tube 830 via a bearing. A driven gear 840 is fixed to the outside of the rotating tube 830. The inlet end of the nozzle 720 is rotatably connected to a connecting tube 850 via a bearing.

[0037] Please refer to it again. Figure 3 The driving gear 820 and the driven gear 840 are meshed together, and the input terminal of the drive motor 810 is electrically connected to the output terminal of the external power supply.

[0038] Please refer to it again. Figure 3 The nozzle 720 is fixed through and in the middle of one side of the rotating tube 830.

[0039] In summary, by starting the drive motor 810, the driving gear 820 is rotated, which in turn drives the driven gear 840 to rotate, causing the rotating tube 830 to rotate, which in turn drives the nozzle 720 to rotate, causing the nozzle 730 to rotate. This allows the steam to heat the inner wall of the mounting tube 700 evenly, avoiding dead zones, improving the heating effect, preventing uneven drying of the paper, and further improving the drying effect.

[0040] Specifically: The structure of the steam assembly 200 has been disclosed in the comparative documents and will not be repeated here.

[0041] In practical use, when drying, those skilled in the art pass the paper between the two drying rollers 710, rotate the turntable 411, which drives the bidirectional screw 410 to rotate, causing the moving seat 420 to move away from each other outside the limit rod 460. This causes the connecting rod 430 to deflect vertically, causing the connecting seat 450 to descend, which in turn causes the second fixed frame 600 to descend, bringing the two drying rollers 710 closer together. This allows the two sides of the paper to adhere to the surface of the drying rollers 710. The steam assembly 200 is activated, allowing steam to enter the nozzle 720 through the connecting pipe 850. The drive motor 810 is activated, driving the drive gear 820 to rotate, which in turn drives the driven gear 840 to rotate, causing the rotating pipe 830 to rotate, which in turn drives the nozzle 720 to rotate, causing the nozzle 730 to rotate. This allows the steam to evenly heat the inner wall of the mounting pipe 700, avoiding dead zones, and evenly heating the drying rollers 710. Afterward, the paper is pulled to rotate the drying rollers 710, thus drying and heating the paper.
